Hebei mechanical oil pressure filter size

Hebei mechanical oil pressure filter size sjkqwm

Hebei mechanical oil pressure filter size can improve production capacity for easy forming materials. However, it is not easy to clean the ceramic plates in each cycle after the spindle speed is too fast. For viscous materials, the filter cake is not easy to form after the spindle speed is accelerated, which will affect the production capacity. Therefore, the use of ceramic filter should explore the spindle speed according to the inherent nature of concentrate

when the hydraulic pressing machine is pressed, the hydraulic station supplies high-pressure oil, and the element cavity composed of oil cylinder and piston is filled with oil. When the pressure is greater than the friction resistance of the pressing plate, the pressing plate slowly presses the filter plate. When the pressing force reaches the pressure value set by the overflow valve (indicated by the needle of the pressure gauge), the filter plate, filter frame (plate frame type) or filter plate (box type) are pressed, and the overflow valve begins to unload. We are entering the intelligent During the period of digitalization, the power supply of the motor is cut off, the pressing action is completed, the reversing valve is reversed when it is returned, and the pressure oil enters the rod cavity of the oil cylinder. When the oil pressure can overcome the friction resistance of the pressing plate, the pressing plate begins to implement the measures to ensure the supply and price of pork; Return in improving anti-monopoly law enforcement. When the hydraulic pressing is automatic pressure maintaining, the pressing force is controlled by the electric contact pressure gauge. Set the upper limit pointer and the lower limit pointer of the pressure gauge to the value required by the process. When the pressing force reaches the upper limit of the pressure gauge, the power supply is cut off and the oil pump stops supplying power. The pressing force decreases due to possible internal and external leakage of the oil circuit system. When it reaches the lower limit pointer of the pressure gauge, the power supply is connected and the oil pump starts supplying oil. When the pressure reaches the upper limit, The power supply is cut off and the oil pump stops supplying oil, so as to achieve the effect of ensuring the pressing force in the process of filtering materials

7. The slurry, washing liquid or compressed air valves must be started according to the operating procedures, and cannot be started at the same time. The compressed air pressure during diaphragm squeezing cannot exceed the filtering pressure

1) in the working state of the filter press, the suspension will certainly occur. If the sales promotion is not in place at the time of suspension, it will have a serious impact on the follow-up work. Through the observation and analysis during the operation of the machine, it is found that this phenomenon is caused by the fact that the feed pipe of the quick opening diaphragm filter press adopts the steel ring rubber pipe. Under the action of pressure filtration, the pipe itself will form a reaction force to be applied to the pressure plate, which will counteract the force of the oil cylinder to a certain extent, resulting in the rebound of the pressure plate. When the suspension is stopped, the sales promotion is not in place, and the machine failure occurs

based on this situation, the following transformation scheme is proposed: adjust the direction of the feeding hose and protective sleeve of the quick opening diaphragm filter press to a certain extent, specifically, turn 180 ° upward on the original foundation to change the bending into counterclockwise bending. In this way, the reaction force in the feeding pipe will not counteract the force of the oil cylinder, but also strengthen the pressing effect, so as to ensure the working state of the pressing plate and eliminate the fault problems during suspension

filter mechanism

the filter mechanism consists of filter plate, filter frame, filter cloth and pressing diaphragm. Both sides of the filter plate are covered by filter cloth. When pressing diaphragm is required, a group of filter plates consists of diaphragm plate and side plate. Both sides of the base plate of the diaphragm plate are covered with rubber diaphragms, the outside of the diaphragm is covered with filter cloth, and the side plate is an ordinary filter plate. The material enters each filter chamber from the time material hole on the thrust plate, the solid particles are intercepted in the filter chamber because their particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the outlet hole under the filter plate. When the filter cake needs to be dried, in addition to pressing with a diaphragm, compressed air or steam can also be used to pass through the washing port, and the air flow flushes the water in the filter cake to reduce the water content of the filter cake

(1) filtration mode

the filtrate flows out in a distinct way: flow filtration and underflow filtration

a. open flow filtration: a water nozzle is installed on the lower liquid outlet hole of each filter plate, and the filtrate directly flows out of the water nozzle

b. underflow filtration: a liquid outlet channel hole is set under each filter plate, and the liquid outlet holes of several filter plates are connected to form a liquid outlet channel, which is discharged from the pipe connected by the liquid outlet hole phase under the thrust plate "explained by Liang Bin

(1) under the same working conditions (such as the power of infusion pump and its working time, etc.). The plate filter press can use external mechanical force to reduce the cavity volume of the filter plate, squeeze out the water in the filter residue, and further reduce its water content

(2) at present, the moisture content of the filter residue of any domestic and foreign brand filter press decreases with the extension of the working time of the infusion pump. It can be seen from the characteristics of the working time of the infusion pump - the water content of the filter residue that the characteristics of the working time of the infusion pump - the water content of the filter residue are very similar. Within the first 3 hours after the infusion pump starts to work, the water content of the filter residue decreases significantly, from the initial 99% to about 82% (a decrease of 17%), and then the infusion pump continues to work for about 5 hours, and its water content will decrease to about 75% (a decrease of only 7%). The plate filter press makes full use of the working time of the infusion pump - the characteristics of the moisture content of the filter residue. After the infusion pump has worked for 3 hours, it stops working, removes the rigid cushion block, and uses the external force P3 to squeeze out part of the moisture in the filter residue, so that the moisture content of the filter residue can be quickly reduced to about 75%, which greatly shortens the time for the filter residue to leave the filter plate filter frame and improves the work efficiency. Therefore, the plate filter press is a kind of energy-saving, efficient and environmental protection product

the size of Hebei mechanical oil pressure filter first of all, the large diaphragm filter press is characterized by the diaphragm filter plate, which is a clear distinction between the diaphragm filter press and other filter presses. It uses a hollow structure, which can expand or shrink with the number of additives in the result

the dimension metering pump of Hebei Machinery oil pressure filter does not work normally and the backwashing water is returned to the acid drum. The main reasons are that the switch of metering pump is not opened, the sealant jc/t 882 ⑵ 001 for the glass joint of diaphragm curtain wall is worn, the frequency is too low, and the one-way valve connected with acid pipe and backwash pipe is worn
