Where is the difference between van filter and plate frame f

　　What is the difference between van filter and plate frame filter?First, let's know what is a press filter?This is a special filter medium that puts a certain pressure on the object for the fluid to seep out.Mechanical equipment is a commonly used solid-liquid separation equipment.The filter plate is stable, convenient operation, safe and labor saving; the metal pressure pipe is made of seamless steel pipe and plastic steel filter plate, high temperature resistance, high pressure and durable.There are two types of van filter and two.What's the difference?This is a brief introduction.

　　First, structural composition

　　Plate frame filter is a filter device for intermittent filter pressure.It consists of a pressing part, a stop plate, a pressing plate, a beam and a frame.All the filter plates and the filter boxes are stacked alternately.It is placed on two equal support beams.All filter plates and the corresponding portions of the filter frame have liquid channels for introducing suspension or discharging liquid.All filter plates have the same sealing surfaces on both sides of the filter box.The filter cloth is sandwiched between the plate and the frame sealing surface. The sealing pad is located inside the filter plate and the frame sealing surface, the filter sealing surface supporting the filter cloth has grooves, and all grooves and filter fluid are discharged.The channel is connected.A press filter consists of multiple parallel filter chambers.Each filter chamber has a filter layer on both sides of the filter chamber to prevent solid phase particles in the suspension from passing through and allowing the filter to penetrate.The total filter area of the filter plate indicates the full production capacity of the press.

　　The plate frame press consists of a filter plate and a filter frame that can withstand low filtration pressure (usually less than 0.6Mpa).Each filter has a different plate frame depending on the size of the area.Filters are usually used for material filtration with fewer particles.Usually used for the filtering of fine products.It can be filtered with the filter paper on the back of the filter cloth.

　　Second, filtering methods

　　The single filter of the van filter is thicker than the plate filter, that is, the van filter is formed by combining two identical filters and the two filters are formed as filter chambers upon compaction.When storing particulate matter separated by the filter cloth, the feed hole is located in the center of the filter plate and is usually used for materials with large particulate matter, such as sewage treatment, mining mining, coal washing, etc.The characteristics of the box filter are not appropriate.The filter room has deflection, does not damage the filter plate, fast filter speed, convenient slag discharge, large filter pressure, filter cake liquid content is low, can withstand up to 3.0 filter pressure Mpa, and automatic pull plate unloading is easy.It has a wider adaptability and can make large presses.

　　Both plate box and van press filter can realize bright current and dark current.According to the washing method of the filter cake, it can be divided into washable type and non-washing type.The type of cleaning is a replacement between the cleaning solution and the filter cake.After the diffusion process, the washing liquid can further wash out the desired products and unnecessary waste liquid contained in the filter cake, and the washing method of the filter cake is obviously mobile and washable., The undercurrent is hable and washable (also known as two-way cross cleaning type).If you choose not to clean, you can only be filtered, can not clean。

　　Third, the comparative advantages and disadvantages

　　Advantages of van press filter:

　　1.Box pressure filter price is low, generally about 5,000 yuan lower than the plate frame filter. 

　　2.Box filter performance is stable, hard, wear resistant, generally than the box filter more than one year.

　　3.The improved automatic filter is more unified and uses the future intelligent development.

　　4.More effective protection filter cloth, make it longer service life, automatic cleaning more convenient.However, it is worth mentioning that the box filter replacement of filter cloth is more complicated.

　　5.When replacing the filter plate, the standard are uniform and no special arrangements are required.

　　Advantages of plate frame filter:

　　1.The plate frame filter has a high filter quality, and the filter cake can be washed back twice, so the filter cake has a high purity.

　　2.It is more efficient and faster, due to the greater filter space than the paradigm press.

　　3.Replacement of the filter cloth is more convenient and fast, effectively improving the utilization rate and improving the filter efficiency.

　　4.The cycle time is long, the same size of the filter plate, the plate filter press has greater storage filter cake space, the gap cycle time is longer.If the same volume of mixture is filtered, the cycle ratio of the box filter is 4:3. This is the characteristic of the box filter.That's why it's more expensive.

　　5.Weight is lighter than a box filter for easy transport and movement.

　　The above is about the difference between van filter and plate frame press.By knowing if you already know how to choose it?Whatever device you choose, we should care for safety.
