A liquid outlet pipe 110 is installed at the bottom of the frame 100. The filter press assembly 200 comprises a liquid inlet pipe 210, a thrust plate 220, a plurality of filter press elements 230 and a push member 240 arranged in sequence along the length direction of the frame 100. The output end of the push member 240 is used to push the plurality of filter press elements 230 to be stacked on each other and attached to the thrust plate 220. Through holes 250 are formed in the plurality of filter press elements 230. The plurality of through holes 250 can be interconnected to form a filter press channel. The liquid inlet pipe 210 is connected to the filter press channel. The metal detector 300 is installed on the liquid outlet pipe 110 to detect the metal concentration of the liquid phase in the liquid outlet pipe 110.

[0024] During implementation, the output end of the push member 240 pushes multiple filter presses 230 to stack on each other and stick to the thrust plate 220, the liquid inlet pipe 210 introduces the slurry into the filter press channel, the solid phase is intercepted on the filter press 230, the liquid phase flows out from the filter press 230 to the bottom of the frame 100, and is discharged from the liquid outlet pipe 110, and the liquid discharged from the liquid outlet pipe 110 is detected by the set metal detector 300. If the metal concentration exceeds the standard, it indicates that material leakage has occurred, which is convenient for reminding the operator to replace the damaged filter cloth 232 in time, reduce the impact on production, and reduce losses.

[0025] The frame 100 in this embodiment is a structure for supporting the filter press assembly 200 , and a liquid outlet pipe 110 is installed at the bottom thereof.

[0026] The filter press assembly 200 in this embodiment can realize the solid-liquid separation function for the slurry, and includes a liquid inlet pipe 210, a thrust plate 220, a plurality of filter press elements 230 and a push member 240 arranged in sequence along the length direction of the frame 100. The output end of the push member 240 is used to push the plurality of filter press elements 230 to be stacked on each other and attached to the thrust plate 220. Through holes 250 are formed in the plurality of filter press elements 230. The plurality of through holes 250 can be interconnected to form a filter press channel. The liquid inlet pipe 210 is connected to the filter press channel.

[0027] The liquid inlet pipe 210 is a structure for introducing the slurry to be separated into solid and liquid into the filter press channel formed by a plurality of filter press elements 230 .

[0028] The thrust plate 220 has the function of limiting the position of the filter press 230 .

[0029] Among them, the filter press 230 includes a plate frame 231 and two filter cloths 232, the two filter cloths 232 are fixed on both sides of the plate frame 231, and through holes 250 are formed at the center of the plate frame 231 and the filter cloth 232. When multiple plate frames 231 are stacked together, the multiple through holes 250 in the center form a filter press channel. During the process of the slurry introduced through the liquid inlet pipe 210 flowing through the filter press channel, it will diffuse to the surroundings, and the solid phase will be intercepted by the filter cloth 232, and the liquid phase will penetrate the filter cloth 232 and flow into the bottom of the frame 100, thereby realizing the solid-liquid separation process.

[0030] The push member 240 may use a hydraulic push rod to push the plurality of filter press elements 230 to be stacked on the thrust plate 220 in a horizontal direction.

[0032] The metal detector 300 in this embodiment is used to detect the structure of the metal content in the liquid phase. When the filter cloth 232 is damaged, it loses at least part of its function of intercepting the solid phase, so that part of the solid phase flows into the bottom of the frame 100 along with the liquid phase and is discharged from the liquid outlet pipe 110. Therefore, the working status of the filter press 230 can be known based on the detection result of the metal detector 300.

[0033] It is understandable that the metal detector 300 is used to detect the metal concentration in the liquid phase, which is a structure that can be thought of by those skilled in the art, and no further elaboration and explanation will be given for this.

[0037] By setting the guide assembly 400, the slurry in the filter press channel can avoid the section corresponding to the damaged filter press element 230. Specifically, the slurry diversion process is achieved by setting the guide plate 410.

[0038] In one embodiment, the side wall of the guide plate 410 is formed with a first guide port 412 of the guide channel 411, and the top of the guide plate 410 is formed with a second guide port 413 of the guide channel 411. The first guide port 412 can be connected to the through hole 250, and the second guide port 413 can be connected to the guide pipe 420.

[0039] The first guide ports 412 of two guide plates 410 are disposed opposite to each other and are in a first position, and the remaining guide plates 410 are in a second position. A material running area M is formed between the two guide plates 410 in the first position.

[0040] To prevent the slurry from flowing into the material running area M, in one embodiment, a sealing strip is provided on the bottom wall of the guide plate 410 , and when the guide plate 410 is located at the first position, the sealing strip abuts against the inner wall of the through hole 250 .

[0041] To prevent slurry from flowing into the chute during normal operation, in one embodiment, a sealing ring is provided on the outer wall of the guide plate 410 and below the first guide port 412 , and when the guide plate 410 is located at the second position, the sealing ring abuts against the inner wall of the chute.

[0043] To facilitate the control of the guide plate 410 so that it can stay firmly in the first position or the second position, in one embodiment, the guide assembly 400 also includes a plurality of locking members corresponding to the plurality of guide plates 410, the locking members are connected to the frame 100, and the output end of the locking member can be connected to the corresponding guide plate 410 to fix the guide plate 410 at the current position.

[0044] It is understandable that the locking member can be implemented by a locking screw, which is threadedly connected to a threaded hole provided on the frame 100 , and the free end of the locking screw can be moved to a position where it abuts against the guide plate 410 .

[0045] Compared with the prior art: the output end of the push member 240 pushes multiple filter presses 230 to be stacked on each other and attached to the thrust plate 220, the liquid inlet pipe 210 introduces the slurry into the filter press channel, the solid phase is intercepted on the filter press 230, the liquid phase flows out from the filter press 230 to the bottom of the frame 100, and is discharged from the liquid outlet pipe 110, and the liquid discharged from the liquid outlet pipe 110 is detected by the set metal detector 300.
