Problems solved by technology

The noise of the bulldozer is loud and the mud cake needs to have a certain strength to withstand the pressure of the bulldozer. Projects that are conveyed by belt conveyors will have belt deviation, slippage, and mud accumulation, and the labor intensity of inspection workers is relatively high.
These two conventional conveying methods have great requirements on the quality of the mud cake fed to the plate and frame filter press, and are not suitable for conveying the mud cake fed to the plate and frame filter press under complex working conditions.

Embodiment 1

[0035] Such as Figure 1-2 As shown in the figure, a conveying device for feeding mud cake of a plate and frame filter press, including a mud hopper 1, a conveyor 2 located directly below the mud hopper 1, and a grille is provided at the lower part of the mud hopper 1 1.1; the grid 1.1 can be a toothed grid, and the toothed grid has a toothed cutting edge for accelerating the division of the mud cake.

[0036] The conveyor 2 includes two main rotating shafts 2.1 and a first rotating motor electrically connected to the main rotating shaft 2.1 on either side thereof, the two main rotating shafts 2.1 are arranged in parallel and spaced apart, and both ends of the main rotating shaft 2.1 are fixed A sprocket is connected, and the sprockets on the same side of the two main shafts 2.1 are located on the same plane and are meshed and connected by a chain 2.2. A plurality of central shafts 2.3 parallel to the main shaft are arranged between the two chains 2.2. The two ends of the cen...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the conveying device further includes a processor, the second rotating motor communicates with the cylindrical roller 2.31 through the processor, and the pressure sensor communicates with the third rotating motor through the processor. Motor communication connection; when the value measured by the pressure sensor exceeds the predetermined value, the processor receives the signal of the pressure sensor, and sends control signals to the second rotating motor and the third rotating motor in sequence to realize automatic control.

Embodiment 3

[0041] A method for conveying mud cake for plate and frame filter press, comprising the following steps:

[0042] S1, the plate and frame filter press discharges the mud cake into the mud hopper 1, and after being destroyed by the lower grille 1.1 of the mud hopper 1, several mud clods with smaller particle sizes fall to the cylindrical drum 2.31 of the conveyor 2 below. upper surface;

[0043] S2, the cylindrical drum 2.31 transports the mud block to the mud outlet gentle slope 3, and the mud block falls from the cylindrical drum 2.31 due to gravity;

[0044] S3, when the cylindrical drum 2.31 moves to directly above the mud discharge gentle slope 3, it is determined whether there is mud left on the current cylindrical drum 2.31;

[0045] S4, if mud material remains on the current cylindrical drum 2.31, then clean the surface of the cylindrical drum 2.31; otherwise, continue to transport the mud.

[0046] Wherein, the specific determination steps in the step S3 include:

Abstract

The invention relates to a device for conveying discharged mud cakes of a plate-and-frame filter press. The device comprises a mud hopper and a conveyor under the mud hopper, and the lower portion ofthe mud hopper is provided with gratings. By additional arrangement of the gratings, with large mud cake breaking power, on the lower portion of the mud hopper, the mud cakes are cut into small-size blocks by the gratings under the action of gravity so as to achieve convenience in transporting. The conveyor conveys cylindrical rollers through a chain-sprocket structure and is less prone to slipping or deflecting and low in operating noise. The multiple cylindrical rollers are arrayed to form an uneven transporting surface which is capable of withstanding direct impact of mud blocks with certain weights, and the concave-convex surface enables increasing of a contact area, so that convenience in mud block conveying is achieved. By arrangement of a roller brush and a cleaning procedure, the whole device for conveying is low in requirement on intrinsic weights of the mud cakes, the conveyor is slightly affected by the moisture content or viscoplasticity of the mud cakes, and the device forconveying is less prone to failure caused by mud accumulation.

Description

technical field [0001] The invention relates to a conveying device for discharging mud cake of a plate and frame filter press. Background technique [0002] At present, there are many dehydration projects using the plate and frame filter press process, and the dewatered cake is mostly transported by bulldozers or belt conveyors. The noise of the bulldozer is loud and the mud cake needs to have a certain strength to withstand the pressure of the bulldozer. The project that is conveyed by the belt conveyor will have the situation of belt deviation, slippage, and mud accumulation, and the labor intensity of the inspection workers is relatively high. These two conventional conveying methods have great requirements on the quality of the mud cake fed to the plate and frame filter press, and are not suitable for conveying the mud cake fed to the plate and frame filter press under complex working conditions. Contents of the invention [0003] Aiming at the technical problems exis...
