All crank unloading device for press filter

Abstract

The invention relates to an all crank unloading device for press filter. At present, there is no all crank unloading device for press filter with reasonable structural design and reliable performance. The device comprises plural all crank unloading mechanisms. The all crank unloading mechanism includes two lower-corner feeding filter plates, two outer crank arms, two inner crank arms, two long cloth supporting swing plates, two short cloth supporting swing plates, a long cloth supporting roll, a short cloth supporting roll, two crank arm connection shafts, two pieces of lower-corner feeding filter cloth, two filter cloth sinker rods, two balance blocks, a sinker rod locking unit, and a suspension vibrating mechanism. One outer crank arm and one inner crank arm on the same side of the lower-corner feeding filter plate are connected via one crank arm connection shaft, the two filter cloth sinker rods are connected at the lower parts of the two pieces of lower-corner feeding filter cloth in a penetrating manner, and adjacent two filter cloth sinker rods in adjacent two all crank unloading mechanisms are fixed through the sinker rod locking unit. The device provided by the invention has unloading assisting effects on both upper and lower half parts of a filter cake during crank unloading.

Description

technical field [0001] The invention relates to a discharge device, in particular to a full varicose discharge device for a filter press, which is a filter cake processing device on the filter cloth of the filter press and belongs to the field of filter press manufacturing. Background technique [0002] In the filter press, the feeding method of the conventional varicose unloading system is intermediate feeding. When unloading the varicose, the varicose only stretches the filter cloth on the half of the filter plate, that is, it only helps to unload the upper half of the filter cake. function, and the opening range of the filter cloth is small, and the shaking effect is poor. Usually, the filter cake in the lower part of the filter cloth of the filter plate still needs to be unloaded manually, which is labor-intensive and low-efficiency. [0003] When the conventional varicose cake is unloaded, because the lower part has no unloading function, the filter cake in the lower pa...

Another example is that the publication date is January 07, 2009, and the publication number is CN 201175603 Chinese patent, which discloses an automatic cleaning device for a filter press with varicose filter cloth, which mainly modifies the Chinese patent publication number CN201676575U The suspension method of the filter cloth suspender in the paper uses two pairs of springs to separate the two filter cloth suspenders on the same filter plate to realize the automatic water flushing filter cloth device. However, the device is generally carried out in the middle in actual application. way of feeding

[0007] To sum up, there is currently no varicose unloading device for a filter press that has a reasonable structure design, reliable performance, and can help unload the upper and lower half of the filter cake during varicose unloading.
