DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a feeding device for a filter press includes a shell body 1, a discharge port 6 and a filter box 9. A discharge port 2 is provided on the top of the shell body 1, and a guide plate 15 is fixedly connected to the bottom of the discharge port 2. The discharge port 6 is provided on one side of the shell body 1, and a fixing plate 7 is fixedly connected to one side of the shell body 1. A vertical plate 18 is fixedly connected to the inside of the shell body 1, and a feeding mechanism is arranged between the vertical plate 18 and the fixing plate 7. The filter box 9 is fixedly connected to the bottom of the shell body 1, and a filter plate 3 is slidably connected to the inside of the filter box 9. An outlet pipe 8 is fixedly connected to one side of the filter box 9, drainage holes 13 are equidistantly provided inside the shell body 1, a pressing mechanism is arranged inside the shell body 1, and a displacement block 16 is slidably connected to the inside of the shell body 1, and a feeding box 11 is fixedly connected to the top of the displacement block 16, and through holes 14 are equidistantly provided at the bottom of the feeding box 11.

[0022] First, filter material is put into the shell 1 through the discharge port 2, and then the filter material enters the feed box 11 through the inclined plate of the guide plate 15, and then the pressing mechanism is started to drive the pressing plate 10 to move downward to squeeze the filter material inside the feed box 11, thereby squeezing the sewage contained in the filter material, and then the squeezed sewage enters the drain hole 13 through the through hole 14, and finally enters the filter box 9, so that the sewage in the filter material can be better discharged, thereby increasing the practicality of the device, and then the sewage enters the top of the filter plate 3 inside the filter box 9, and the sewage is filtered and purified by the filter plate 3, and then the purified sewage is discharged through the outlet pipe 8, and the filter material after the pressing is completed is driven by the feeding mechanism to move out of the feed box 11 through the outlet port 6, so that the filter material can be better processed subsequently, thereby further increasing the practicality of the device.

[0023] like Figure 1-Figure 4As shown, the feeding mechanism includes a first reciprocating screw 12, which is rotatably connected between the vertical plate 18 and the fixed plate 7, and the interior of the displacement block 16 is threadedly connected to the exterior of the first reciprocating screw 12. The feeding mechanism also includes a guide rod 17, which is fixedly connected between the vertical plate 18 and the fixed plate 7, and the exterior of the guide rod 17 is slidably connected to the interior of the displacement block 16. A second motor 24 is fixedly installed on one side of the vertical plate 18, and one end of the output shaft of the second motor 24 is fixedly connected to one end of the first reciprocating screw 12.

[0024] When the filter material is removed, the output shaft of the second motor 24 is started to rotate, driving the first reciprocating screw 12 to rotate and driving the displacement block 16 to slide on the outside of the guide rod 17. The guide rod 17 makes the displacement block 16 move more smoothly, thereby driving the feed box 11 to move out from the discharge port 6. Then the staff can more conveniently perform subsequent processing on the filter material inside the feed box 11, thereby increasing the practicability of the device.

[0025] like Figure 1-Figure 4 As shown, the pressing mechanism includes a second reciprocating screw 21, which is rotatably connected between the guide plate 15 and the inner wall of the shell 1, and a first motor 5 is fixedly installed on one side of the shell 1, and one end of the output shaft of the first motor 5 is fixedly connected to one end of the second reciprocating screw 21. The pressing mechanism also includes a slider 19, which is threadedly connected to the outer side of the second reciprocating screw 21, and a slide rod 20 is fixedly connected between the guide plate 15 and the inner wall of the shell 1. The interior of the slider 19 is slidably connected to the outer side of the slide rod 20, and a displacement plate 4 is slidably connected to the top of the shell 1, and a pressing plate 10 is fixedly connected to the bottom of the displacement plate 4.

[0026] When the filter material is pressed, the output shaft of the first motor 5 is started to rotate, driving the second reciprocating screw 21 to rotate and driving the slider 19 to slide on the outside of the slider 20. The slider 20 guides the moving direction of the slider 19 to avoid the problem of displacement of the slider 19 during movement. Then the slider 19 moves and drives the limit rod 22 to slide inside the limit groove 23, thereby driving the displacement plate 4 to move inside the shell 1, and then drives the pressure plate 10 to approach the inside of the feed box 11, so as to press the filter material, and then better discharge the sewage in the filter material.

[0027] The utility model provides a feeding device for a filter press, and the specific working principle is as follows: first, filter material is put into the interior of the shell 1 through the feed opening 2, and then the filter material enters the interior of the feed box 11 through the inclined plate of the guide plate 15, and then the output shaft of the first motor 5 is started to rotate to drive the second reciprocating screw 21 to rotate and drive the slider 19 to slide on the outside of the slide rod 20, and the sliding bar 20 guides the moving direction of the slider 19 to avoid the problem of the slider 19 being offset when moving, and then the slider 19 moves to drive the limit rod 22 to slide inside the limit groove 23, thereby driving the displacement plate 4 to move inside the shell 1, and then driving the pressing plate 10 to approach the interior of the feed box 11. , thereby pressing the filter material, and thus better discharging the sewage in the filter material. Next, by starting the second motor 24 output shaft to rotate, the first reciprocating screw 12 is driven to rotate and the displacement block 16 is driven to slide on the outside of the guide rod 17. The guide rod 17 makes the displacement block 16 move more smoothly, thereby driving the feeding box 11 to move out of the discharge port 6. Then the staff can more conveniently perform subsequent treatment on the filter material inside the feeding box 11, thereby increasing the practicality of the device. Finally, the sewage enters the top of the filter plate 3 inside the filter box 9, and the sewage is filtered and purified by the filter plate 3, and then the purified sewage is discharged through the outlet pipe 8.
