The slag loading bucket is detachably connected to the slag collecting hopper, which greatly facilitates the transfer and cleaning of the filter cake pieces placed in the slag loading bucket, achieving a highly efficient cleaning effect of the filter press on the filter cake, greatly saving the time required for manual cleaning, and reducing the labor cost required for cleaning the filter cake.

Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a filter press sludge unloading device. Background Technology

[0002] A filter press is a widely used filtration device for solid-liquid separation. It forces liquid through a filter medium (filter cloth) under high pressure, while solid particles are trapped and form a filter cake. The filter press designed in this scheme is suitable for solid-liquid separation processes in industries such as wastewater treatment, mining, chemical, food, and pharmaceuticals, and features high efficiency, energy saving, and a high degree of automation. In traditional filter presses, when the suspension is pumped into the filter chamber and discharged through the filter cloth under pressure, while solid particles are trapped and form a filter cake, this cake naturally falls off from the bottom of the chamber. Because there is no corresponding unloading structure, these fallen filter cakes often require manual cleaning and transfer, resulting in low cleaning efficiency and high labor costs. Therefore, there is an urgent need for a filter press sludge unloading device to assist in unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a filter press unloading bucket device to solve the problems of low cleaning efficiency and high labor costs of traditional filter press filter cake.

[0004] The present invention provides the following technical solution: a filter press sludge unloading device, comprising a filter press module and a sludge unloading module respectively. The filter press module includes a filter plate mechanism and a clamping mechanism. The filter plate mechanism includes multiple filter plates stacked and arranged in a horizontal direction. The clamping mechanism includes a thrust plate, a clamping plate and a push rod. The thrust plate abuts against the filter plate located on one side of the filter plate mechanism, and the clamping plate abuts against the filter plate on the side away from the thrust plate. The push rod can move axially to drive the clamping plate closer to or away from the thrust plate. The sludge unloading module includes a sludge collecting hopper and a sludge loading bucket. The sludge collecting hopper is provided with a sludge inlet corresponding to the filter plate mechanism and a sludge outlet corresponding to the sludge loading bucket. The sludge loading bucket is provided with a receiving port, and the sludge loading bucket is detachably connected to the sludge collecting hopper, so that the receiving port can be connected to or disconnected from the sludge outlet.

[0005] As described above, a filter press sludge unloading bucket device has multiple casters on the lower side of the sludge loading bucket, which allows the material receiving port to be moved closer to or offset away from the sludge discharge port.

[0006] As described above, the sludge unloading device for a filter press further includes a locking mechanism disposed between the sludge collecting hopper and the sludge loading hopper. The locking mechanism includes a fixed base, a fixed hook, a wrench, and a locking element. One end of the wrench is hinged to the fixed base, and one end of the locking element is hinged to the middle of the wrench. The swinging of the wrench causes the end of the locking element away from the hinge to move closer to or away from the fixed hook.

[0007] As described above, in a filter press sludge unloading bucket device, the fixed base is located on the edge of the sludge loading bucket near the material receiving port, and the fixed hook is located on the edge of the sludge collecting hopper near the sludge discharge port.

[0008] As described above, in a filter press sludge unloading bucket device, the sludge loading bucket is square, so that both the material receiving port and the sludge discharge port are square, and the locking mechanism consists of multiple units located around the sludge loading bucket.

[0009] As described above, in a filter press sludge discharge bucket device, the sludge inlet is square in shape, and the area of ​​the sludge inlet is larger than that of the sludge outlet.

[0010] As described above, in a filter press sludge unloading bucket device, the sludge collecting hopper is further provided with a material discharge inclined surface connected between the sludge inlet and the sludge outlet, the sludge outlet is located below the sludge inlet, and the material discharge inclined surface is inclined toward the sludge outlet.

[0011] As described above, in a filter press sludge unloading device, the sludge inlet is located on the lower side of the filter plate mechanism.

[0012] As described above, in a filter press sludge unloading bucket device, the filter plate mechanism further includes a support rod mounted on the side of the thrust plate and the top clamping plate, with both sides of the filter plate simultaneously mounted on the support rod.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This utility model discloses a filter press unloading hopper device. In addition to the existing filter press module, a slag unloading module is added. The filter press module uses a clamping mechanism to compress the filter plates, causing water to drain from the solid particles between the multiple filter plates, forming filter cakes. These filter cakes fall naturally under gravity after the clamping mechanism releases its pressure. The slag unloading module includes a slag collecting hopper and a slag loading bin. The slag collecting hopper collects and gathers the fallen filter cake pieces, which then fall into the slag loading bin through the slag outlet. The slag loading bin is detachably connected to the slag collecting hopper, greatly facilitating the transfer and cleaning of the filter cake pieces in the slag loading bin. This achieves highly efficient cleaning of the filter cake by the filter press, significantly saving the time required for manual cleaning and reducing the labor costs associated with cleaning the filter cake.
