Vibrating cake unloading device of filter press with filter cloth provided with falling rod

Abstract

According to the vibration cake discharging device of the filter press with the filter cloth and the falling rod, the length of the bottom of the filter cloth exceeds that of a filter plate, the falling rod is arranged at the bottom of the filter cloth, a cross beam is arranged at the bottom of the filter press and is parallel to a rack, a row of continuous triangular teeth are arranged on the cross beam, and the height of the falling rod is lower than the tooth tops of the triangular teeth; when the filter plate is pulled open to discharge a cake, the falling rod can be dragged to move among the triangular teeth, so that the falling rod can drive the filter cloth to continuously fluctuate and vibrate, and the filter cake adhered to the filter cloth can be vibrated down; the device is simple in structure, convenient to install, low in production cost, reliable in operation, low in failure rate and wide in applicable machine type.

Description

Technical Field

[0001] The utility model belongs to the field of filter presses in the solid-liquid separation industry, and more particularly relates to a vibrating cake unloading device for a filter press with a filter cloth and a sinker rod. Background Art

[0002] The filter press is an important solid-liquid separation equipment. The filter plate is closed to form a closed filter chamber. The filtered material enters the various chambers of the filter plate through the pressure of the feed pump. The solid particles in the material are trapped by the filter medium filter cloth, forming a filter cake in the filter chamber. The filtrate is discharged through the drainage holes of the filter plate. The filter plate is pulled apart by the plate puller, and the filter cake falls off the surface of the filter cloth to complete the cake unloading. In the filtration industry, due to the different properties of materials, especially in some chemical industries where the material viscosity is relatively high, the filter cake sticks to the filter cloth and is not easy to separate and fall off. It is necessary to use tools to manually peel the filter cake from the surface of the filter cloth, which has low production efficiency and the filter cloth is easily damaged. Utility Model Content

[0003] The utility model aims to solve the shortcomings of the above-mentioned background technology and provide a vibrating cake unloading device for a filter cloth belt sinker filter press.

[0004] The vibrating cake unloading device of the filter cloth filter press with a sinker bar comprises: a sinker bar, a crossbeam, and triangular teeth. The length of the bottom of the filter cloth exceeds the filter plate. The sinker bar is arranged at the bottom of the filter cloth. The crossbeam is arranged at the bottom of the filter press and is parallel to the frame. A row of continuous triangular teeth is arranged on the crossbeam. The height of the sinker bar is lower than the tooth top of the triangular teeth. When the filter plate is pulled open to unload the cake, the sinker bar will be dragged to move between the triangular teeth, so that the sinker bar will drive the filter cloth to vibrate continuously, and the filter cake adhered to the filter cloth will be vibrated off.

[0005] Preferably, the two sides of the sinker rod extend beyond the filter cloth, there are two cross beams, the distance between the two cross beams exceeds the filter cloth, and the distance between the two cross beams is smaller than the sinker rod; in this way, when the filter plate is pulled, the sinker rod will scratch the triangular teeth without damaging the filter cloth, and when the filter plate is pulled open to unload the filter cake, the filter cake will not fall on the cross beam.

[0006] The utility model discloses a vibrating cake unloading device for a filter press with a filter cloth and a sinker rod. When the filter plate is pulled open to unload the cake, the sinker rod will be dragged to move between the triangular teeth, so that the sinker rod will drive the filter cloth to vibrate continuously, and the filter cake stuck on the filter cloth will be vibrated off. The utility model has the advantages of simple structure, convenient installation, low production cost, reliable operation, low failure rate and wide application range. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 The utility model is a schematic diagram of a vibrating cake unloading device of a filter cloth belt sinker filter press.

[0008] Figure 2 The utility model is a side view of the vibrating cake unloading device of the filter cloth with sinker filter press.

[0009] In the figure: 1. filter plate; 2. filter cloth; 3. sinker rod; 4. crossbeam; 5. triangular gear; 6. frame. DETAILED DESCRIPTION

[0010] In order to have a further understanding and recognition of the structural features and the effects achieved by the present invention, a preferred embodiment and accompanying drawings are used for detailed description as follows:

[0011] like Figure 1 , Figure 2 As shown, the bottom length of the filter cloth 2 exceeds the filter plate 1, and the sinker 3 is arranged at the bottom of the filter cloth 2, and the two sides of the sinker 3 exceed the filter cloth 2; two crossbeams 5 are arranged at the bottom of the filter press and are parallel to the frame 6, the distance between the two crossbeams 4 exceeds the filter cloth 3, and the distance between the two crossbeams 4 is smaller than the sinker 3; a row of continuous triangular teeth 5 is arranged on the crossbeam 4, and the height of the sinker 3 is lower than the tooth top of the triangular teeth 5; when the filter plate 1 is pulled open to unload the filter cake, the sinker 3 will be dragged to move between the triangular teeth 5, so that the sinker 3 will drive the filter cloth 2 to vibrate continuously, and the filter cake stuck on the filter cloth 2 will be vibrated off.
