Description

Technical Field

[0001] This utility model relates to the field of filter press equipment application technology, specifically to an automatic filter cake sampling device for a filter press. Background Technology

[0002] High-efficiency horizontal filter presses are solid-liquid separation equipment used in the mineral processing and dewatering industry. The filtration process involves the solid-liquid mixture being fed into the filter chambers via the inlet. The filter cloth traps solid particles in the chambers, forming a filter cake. Backwash water is injected into the filter cake through the inlet for washing, and the filtrate is discharged through the filtrate holes. The filter cake falls under its own weight onto a belt conveyor, which then transports it to the material silo. For sampling, the high-efficiency horizontal filter press needs to be running at the unloading stage. Sampling personnel then stop the belt conveyor by pulling a rope switch and climb onto the working surface to collect samples. However, manual sampling presents several problems: personnel must pause the operation of the high-efficiency horizontal filter press to complete the sampling, reducing its efficiency; climbing over guardrails and onto the belt conveyor poses safety risks such as falls from heights, being struck by objects, and mechanical injuries; and the high labor intensity for personnel does not meet the requirements of unmanned management in enterprises. Utility Model Content

[0003] This invention provides an automatic filter cake sampling device for a filter press to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic filter cake sampling device for a filter press includes a rotating platform mounting plate, a mounting column rotatably connected to an opening in the rotating platform mounting plate, a sampling box connected to the mounting column, and a limiting block on the side of the rotating platform mounting plate corresponding to the sampling box.

[0006] Furthermore, a rotating platform motor is fixedly installed at the opening of the rotating platform mounting plate, the rotating platform motor is connected to a coupling, the coupling is connected to a cross bearing, and the mounting column and the cross bearing are coaxially connected.

[0007] Furthermore, a bottom brace is also connected between the mounting column and the sampling box.

[0008] This utility model has the following beneficial effects:

[0009] This utility model provides an automatic filter cake sampling device for a filter press, mainly composed of a rotating platform mounting plate, a rotating platform motor, a coupling, a cross bearing, and a sampling box. By adding a rotating platform mounting plate to the moving path of the plate-pulling trolley in a high-efficiency horizontal filter press, and installing a rotating motor on the mounting plate to drive the sampling box to rotate, the sampling box ensures filter cake collection after rotating from the initial position to the sampling position. The operator can then remove the filter cake from the sampling box for further testing. This achieves rapid, safe, and efficient sampling of the filter cake, further improving the overall production efficiency of the filter press. It solves the problem that current filter press filter cake sampling methods, which typically involve operators pulling a rope switch to stop the conveyor belt and then climbing onto the belt's working surface to complete the sampling, often result in time-consuming and labor-intensive downtime sampling and high operational risks for the operators.

[0010] This utility model is designed specifically for the structural characteristics of high-efficiency horizontal filter presses. The use of a rotating sampling platform allows for sampling without stopping the machine, thus improving the hourly efficiency of the high-efficiency horizontal filter press. Testing personnel no longer need to climb over guardrails or ascend the conveyor belt to collect samples, improving the safety of sampling operations and reducing labor intensity. The design is simple in structure, easy to operate, widely adaptable, and highly practical, making it suitable for widespread use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-3 As shown, an automatic filter cake sampling device for a filter press includes a rotating platform fixed mounting plate 1. A mounting column 6 is rotatably connected to the opening of the rotating platform fixed mounting plate 1. A sampling box 5 is connected to the mounting column 6. A limiting block 8 is also provided on the side of the rotating platform fixed mounting plate 1 corresponding to the sampling box 5.

[0018] A rotating platform motor 2 is fixedly installed at the opening of the rotating platform mounting plate 1. The rotating platform motor 2 is connected to a coupling 3, and the coupling 3 is connected to a cross bearing 4. The mounting column 6 and the cross bearing 4 are coaxially connected.

[0019] A bottom brace 7 also connects the mounting column 6 and the sampling box 5.

[0020] In practical applications, when the high-efficiency horizontal filter press performs the unloading procedure, the filter plates are pulled apart one by one by a pull-plate trolley for unloading. When the trolley reaches the position of the rotating platform fixed mounting plate 1, the inspector presses the power switch, and the rotating sampling mechanism fixed on the rotating platform fixed mounting plate 1 begins to perform the sampling action. The rotating platform motor 2 drives the mounting column 6 connected to the sampling box 5 to rotate through the coupling 3 and the cross bearing 4. The sampling box 5 rotates with the mounting column 6, and then through the two limit blocks 8 on the rotating platform fixed mounting plate 1, the sampling box 5 is rotated 90° from the initial position to the sampling position and blocked and limited. After the sampling box 5 has finished sampling from the pull-plate trolley, the inspector can take out the filter cake from the sampling box 5 for further testing. The whole sampling process is safe and efficient. Therefore, the device has good practicality.
