Feed pressure of sludge filter press, filter press and feed pressure

  After the sludge filter press works normally, it can be stopped
The pressure and temperature during filtration are within the regular range
If it is too high, it will lead to leakage
If the temperature is too high, the plastic filter plate will deform
The concentration of sludge filter press suspension shall be average
Do not mix with sundries
After removing the filter cake, please wash the filter cloth and filter plate
There shall be no residue on the sealing surface or feed channel, otherwise the flatness of the belt filter press and the tightness of the filter plate will be affected
This will cause deformation and damage of the filter plate due to uneven pressure on both sides of the filter plate
The selection of filter cloth meets the filtering technical requirements of filtrate
The new filter cloth shall be shrunk before installation
The diameter of the opening shall be less than the aperture of the filter
When the filter press is equipped with a filter plate, the holes and holes shall be relatively concentric
The feed hole cloth shall be tightly attached to the pipe wall, otherwise the filter screen is not clear, the filtration rate is low, the pipe is broken, and the expected filtration effect cannot be achieved

html After, the feeding operation can be stopped
Sufficient smooth oil shall be added for mechanical tightening of gearbox components and reducer; Check the hydraulic pressure, check the oil storage capacity of the oil tank and the working pressure of the hydraulic station
Please note that under normal circumstances, the hydraulic oil should be changed once a year
If there is less intermediate hydraulic oil, it shall be supplemented in time
When changing hydraulic oil with belt filter press, please pay attention to the overall cleanliness of the hydraulic system
The working pressure of the hydraulic station is less than the working pressure of the hydraulic cylinder, but not lower than the rated value of the filter pressure
Because it is too small, it will cause a lot of leakage, and the components will damage the machine
When the liquid passes through the filter cloth, it will intercept the solid and complete the solid-liquid separation
At this time, the filtrate is cleared and collected through the outlet pipe under the filter plate
Water from different outlet channels moves together, flows out to the drain valve of a single filter plate, and then separates the filter press
Firstly, the filtrate is pumped into the inlet pipe through the inlet pump, and then the inlet pump gradually increases the filtrate in the inlet pipe to make the filtrate enter the two distribution pipes under high pressure The water piping is connected to the two inlet flanges above the sludge filter press, so that the filtrate enters the two distribution pipes above the filter plate of the filter press, and the distribution pipes are pressed one by one by the filter plate
Crimped together, and on one side in the average direction of each filter plate, there is a channel or groove leading to the central notch of the filter plate
In this way, the filtrate from the filter plate distribution pipe is distributed into a filter chamber composed of a filter plate and a plate frame
In practice, the geomembrane manufacturer flows into the plate frame wrapped by two filter cloth
When in contact with the filter cloth, the liquid in the filter will also pass through the filter cloth under the intense pressure trend
The filter cloth only allows the liquid to pass through, while the solid is intercepted and stored in the filter chamber
First of all, what is sludge filter press? It is a solid-liquid separation equipment commonly used in many industries
Any machine that needs to be used for a long time needs maintenance
Cars need to change oil and tires need to be smooth
If the maintenance is not stopped, the frequently used machine will have many problems
Therefore, people will encounter many problems
In the process of using the machine, stop a lot of maintenance of the machine
As the filter press works frequently, more maintenance is required
Sometimes, due to long working time and high temperature and high pressure environment, the filter press will have transitional function
In the transition work, we need to do some work to simplify it so that the filter press can operate better
Therefore, it is necessary to understand the transition work of the filter press
Next, let's talk about some performance of the transition work of the filter press
The poor quality of filter cake after filtration is the main performance of pressure filtration equipment
Once the filter chamber is not good, it is difficult to achieve the solid-liquid separation effect
The moisture content and molding effect of the filter cake may not reach the ideal effect, or the moisture content of the filter cake may be very high, or the filter cake may not be filled
The transition work of filter press such as filter chamber space is first reflected in the power system
The filter pressing power system provides power for the operation of equipment components and provides strong pressure on the filter plate to make the filter plate in a * filtering environment
When the filter press works for a long time, the hydraulic oil of the hydraulic system may overheat, so that the hydraulic oil is no longer under strong pressure, and its volume will change with the pressure, which directly leads to the failure of the hydraulic system
Generate enough strength
In the working process, when the power system of the equipment cannot normally generate pressure, the pressure acting on the filter plate will naturally fall, and the pressure acting on the filter plate will naturally fall
Therefore, the filter chamber is naturally controlled by the filter and it cannot resist the influence of filtrate, and the natural filter chamber will leak
Once the filtrate leaks, it will directly lead to the reduction of the filtration efficiency of the filter press
This is the secondary performance of over working filter press equipment The article comes from: http://www
