Advantages and disadvantages of belt filter press

Advantages and disadvantages of belt filter press

Advantages

1. Belt filter press can process special sludge,

Some sludge, for example: railway, oil and sludge produced by treating wastewater with diatomite. Other types of filter presses cannot process well, and belt filter press can achieve good results.

2. Low energy costs

Under the same circumstances, the belt filter press has the same treatment effect as other filter presses, but the water consumption and power consumption is only 1/3 of other equipment.

3. Small space occupation

Due to the special structure, the belt filter press occupies only 1/2 of the equipment. Buit achieves the same treatment effect as other filter presses.

4.Stable operation and long service life

The filter belt with machine has high strength and short length. Because of the special adjustment structure, it is not easy to damage. The filter belt has long service life and stable operation. High-strength stainless steel bearings are used instead of conventional carbon steel bearings. The corrosion resistance is greatly improved and the service life of the equipment can reach 10 years.

5.Easy operation

Due to the simple structure and reasonable design, the operation of the belt filter press is not as complicated as other filter presses, even ordinary workers can operate it.

6.Continuous operation

The belt filter press does not operate intermittently like other filter presses. The belt filter press guarantees continuous operation for 24 hours.

Disadvantages:

1.It&#;s suitable for high sludge moisture content

2.Maintenance is difficult.

After many customers have purchased the filter press, because they do not understand professional knowledge and are easy to operate errors, various errors will occur in the filter press equipment. How to operate the filter press safely? What are the precautions? Today, the editor will introduce to you.

Precautions for the use of filter press:

1. Only the normal filter press can be used for feeding work, and the whole machine must be inspected comprehensively before each shift. The mechanical compression transmission components and the reduction box must be filled with enough lubricating oil; the hydraulic compression review the oil tank storage and hydraulic station working pressure, the hydraulic oil is generally replaced once a year, and the hydraulic system should be thoroughly cleaned once during the replacement, and the hydraulic station working pressure It is less than the maximum working pressure of the oil cylinder, but the minimum can not be lower than the allowable value of the filter pressure.

2. It is forbidden to start working in the factory when the number of filter plates is less than the specified number, so as to avoid damage to the machine parts. Check the arrangement of the filter plates before feeding. The filter cloth should not be folded to prevent large leakage; after unloading the cake, the filter plates must be tightly compressed and arranged neatly.

3. After everything is normal, the filter plate can be compressed and filtered. The filter pressure and temperature must be within the specified range. Excessive filtration pressure will cause leakage. If the filtration temperature is too high, the plastic filter plate is easy to deform and the suspension is added. To be evenly concentrated. There must be no impurities; the filter cloth and filter plate must be rinsed after unloading the cake, and residues are not allowed to stick to the sealing surface or the feeding channel, otherwise, it will affect the smooth flow of the feed and the tightness of the filter plate, which will cause the two sides of the filter plate. Unbalanced pressure causes deformation and damage to the filter plate.

4. The filter cloth selection of the filter press must meet the technical requirements of the filter paddle. The new filter cloth should be shrunk before production, and the opening diameter should be smaller than the filter plate aperture. When the filter plate is matched, the cloth hole and the plate hole should be relatively concentric. The feed hole cloth should be close to the wall of the cylinder, otherwise, it will cause unclear filtration, low filtration rate, rupture of the cloth cylinder, and failure to achieve the expected filtering purpose.

5. In the initial stage of filter press, the filter is turbid. When a layer of the filter cake is formed on the filter cloth, the filtrate will become clear. If the filtrate has been turbid or mixed, it may be that the filter cloth is damaged or the cloth holes are different from the plate holes. At this time, close the valve or stop feeding to replace the filter cloth. A small amount of leakage caused by the capillary phenomenon of the filter cloth is allowed between the filter plates.

6. When moving the filter plate, the force should be even and appropriate, and no collision or beating is allowed, so as not to damage the sealing surface and the filter handle. After a period of use, the filter cloth will harden and its performance will decrease. For this reason, regular inspections are required. If changes are found to affect the filtration rate, the corresponding low-concentration weak acid, and weak alkali can be used to neutralize and clean the filter cloth to restore its function. If it cannot be restored, replace it in time.

7. Slurry, lotion, or compressed air valves must be activated in accordance with the operating procedures and cannot be activated at the same time. The compressed air pressure during diaphragm squeezing cannot exceed the filtration pressure.
