Description

The utility model relates to devices for the continuous dehydration of various materials, for example, peat, requiring the extraction of excess moisture from them and can be used in various industries.

Known continuous belt filter press (SU No. 1045900, class B01D 33/4, publ. 07.10.83, bull. No. 37), containing a frame with mounted drive and tension drums, between which filter belts are stretched, and squeezing rollers sequentially installed along the movement of the tapes. In this case, the filter belts are installed at an angle to one another with the formation of a wedge gap.

The disadvantage of this filter press is the inability to adjust the angle between the upper and lower filter belts.

A continuous belt filter press is known (Peat Handbook. M., Nedra, 1982, 760 pp.), Which consists of a frame with a loading device installed on it, filter belts, rollers, hydraulic cylinders and a drive. In this case, the filter belts are installed at an angle to one another, so that they form a wedge gap.

However, it is not possible to adjust the angle between the upper and lower filter belts.

Closest to the proposed utility model is a press for continuous dewatering of material, mainly peat (SU No. 578198, class B30B 9/24, publ. 10/30/1977, bull. No. 40), containing a frame with a loading hopper, two drive moisture-permeable top sheets and lower, approaching in the direction of movement of the squeezed material, which are held in this position by pressure and support rollers.

The disadvantage of this filter press is that it is not possible to adjust the angle between the upper and lower filter sheets.

The problem of the utility model is the development of a continuous belt filter press with the ability to control the angle between the filter sheets.

The technical result of the utility model is to improve the quality of the squeezed material according to the humidity obtained by setting the optimal angle between the filter sheets, which corresponds to the physico-mechanical characteristics of the squeezed material.

The problem posed and the technical result are achieved in that the continuous belt press filter consists of a frame with a loading hopper, upper and lower filter belts, which are pulled together in the direction of movement of the squeezed material, mounted on parallel horizontal drive shafts, and also of tension shafts, pressure and support rollers, according to the utility model, over the tension shaft of the upper filter cloth, an additional device for turning the upper filter cloth from relative to the axis of the drive shaft of the upper filter cloth.

As a device for turning the upper filter cloth using a hydraulic cylinder.

The installation of a device for rotating the upper filter cloth relative to the axis of the drive shaft of the upper filter drive shaft over the tension shaft of the upper filter cloth allows you to adjust the angle a between the upper and lower filter cloths in accordance with the physicomechanical characteristics of the squeezed material, which improves the quality of the pressed material in terms of the moisture content.

The utility model is illustrated by drawings, where in FIG. 1 is a perspective view of a belt filter press, and FIG. 2 is a transverse section aa of the filter press.

The continuous belt filter press consists of a frame 1 with a loading hopper 2. On the frame 1 there are drive shafts upper 3 and lower 4 (drive not shown conventionally), as well as tension shafts 5 and 6, on which filter belts upper 7 and lower are installed 8, while the upper filter cloth 7 is installed at an angle a to the lower filter cloth 8. On the upper filter cloth there are pressure rollers 9 with hydraulic cylinders 10 and a support roller 11. Support rollers 11 are also installed on the lower filter cloth 11. Above The upper tensioning shaft 5 on the frame 1 has a hydraulic cylinder 12, which is pivotally connected to the axis of the tensioning shaft 5. To remove the squeezed water from the upper filter cloth 7, a pan 13 is installed, and the bottom of the filter cloth 8 has a pallet 14. Cleaning rollers 3 and 4 knives 15. The inner space of the filter press is filled with squeezed material 16.

The filter press is as follows. First, depending on the physicomechanical characteristics of the material to be pressed out, the hydraulic cylinder 12 sets the required angle a of the inclination of the upper filter cloth 7 to the lower cloth 8. Then, the filter material 16 is loaded into the hopper 2, after which the drive shafts 3 and 4 are turned on. The incoming material 16 is continuously enters the extraction zone, from which filtered water from the upper filter cloth 7 flows into the pan 13, and from the lower filter cloth 8 flows into the pan 14, and then is discharged into the sewer.

The pressed material 16 after filtration is cleaned from the surface of the filter sheets 7 and 8 with knives 15, after which it is sent for further processing.

The utility model is available for manufacture in engineering plants and may find application for filtering various materials, such as peat.

The utility model is currently at the technical proposal stage.
