The fixed sleeve is arranged on the leg of the liquid receiving flap, close to the bearing seat where the long axis of the liquid receiving flap is located. A movable fixed shaft is arranged in the middle of the fixed sleeve. The support plate is arranged at the end of the long axis of the liquid receiving flap, and the outer diameter of the rotation of the support plate exceeds the fixed sleeve. However, the above device does not have a mechanism for lubricating the rotating shaft, and it is necessary for the staff to manually lubricate the rotating shaft, which is not conducive to reducing the workload of the staff. Moreover, the above device needs to limit the rotating shaft by manually tightening the bolt by the staff, and the operation is relatively cumbersome.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] As Figures 1 to 4 shown, this embodiment proposes a liquid-receiving flap anti-opening device for a filter press, including two groups of support blocks 5. Two groups of mounting blocks 6 are rotatably connected in the middle of the two groups of support blocks 5. The top of one group of mounting blocks 6 is fixedly connected with a left flap 1, and the top of the mounting block 6 is fixedly connected with a right flap 2. Rotating shafts 18 are installed inside the two groups of mounting blocks 6. Both ends of the rotating shaft 18 are rotatably connected inside the support block 5. A number of balls 19 are arranged outside the rotating shaft 18. The balls 19 are rotatably connected inside the mounting groove 17. Driving the balls 19 to rotate inside the mounting groove 17 by rotating the rotating shaft 18 is beneficial to reducing the friction of the rotating shaft 18. A sponge pad 16 is fixedly connected outside the mounting groove 17; lubricating oil inside the sponge pad 16 is rubbed onto the surface of the rotating shaft 18 by the rotation of the balls 19 to lubricate the rotating shaft 18, without the need for staff to manually apply lubricating oil, which is beneficial to reducing the workload of the staff. Through grooves are opened at both ends of the two groups of support blocks 5. A connecting pipe 4 is fixedly connected to the top of the through groove. The top of the connecting pipe 4 is threadedly connected with an oil storage tank 3; it is convenient to disassemble the oil storage tank 3. By providing the oil storage tank 3, the lubricating oil flows into the sponge pad 16 through the connecting pipe 4. The sponge pad 16 is fixedly connected inside the through groove. The bottom end of the sponge pad 16 is closely connected with the balls 19, and the top end of the sponge pad 16 is fixedly connected with the connecting pipe 4.

[0026] In this embodiment, the lubricating oil is stored in the storage oil tank 3, so that the lubricating oil wets the sponge pad 16 through the connecting pipe 4. The rotation of the rotating shaft 18 drives the rotation of the ball 19, so that the lubricating oil inside the sponge pad 16 rubs against the surface of the rotating shaft 18 to lubricate the rotating shaft 18, which is beneficial to reducing the workload of the staff. By providing a storage oil tank 3 threadedly connected to the connecting pipe 4, it is convenient to disassemble the storage oil tank 3 to replenish the lubricating oil inside and keep the sponge pad 16 moist.

[0027] Embodiment 2

[0028] As Figures 3 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the top of a set of the support blocks 5 is fixedly connected with a mounting seat 10. One side of the mounting seat 10 is rotatably connected with a hydraulic rod 9, and the output end of the hydraulic rod 9 is fixedly connected with a connecting rod 8; by driving the hydraulic rod 9 to drive the connecting rod 8 to contract, the fixed block 7 is driven to move horizontally, driving the mounting block 6 to rotate and driving the right flap 2 to flip. The connecting rod 8 is rotatably connected with a fixed block 7 on the side far from the hydraulic rod 9, and the bottom end of the fixed block 7 is fixedly connected with a set of mounting blocks 6; the top of one set of the mounting blocks 6 is rotatably connected with a connecting rod 11, and one side of the other set of mounting blocks 6 is rotatably connected with a connecting rod 11; by the rotation of the mounting block 6 driving the connecting rod 11 to rotate, the other mounting block 6 is driven to rotate to drive the left flap 1 to flip. A chute 15 is formed on the surface of the other set of support blocks 5, a cylinder 13 is fixedly connected inside the chute 15, and a clamping block 14 is fixedly connected to the top end of the cylinder 13. The clamping block 14 is slidably connected inside the chute 15; by driving the cylinder 13 to drive the clamping block 14 to slide along the chute 15, the top end of the clamping block 14 is inserted into the card slot 12, which is beneficial to preventing the mounting block 6 from flipping. Card slots 12 are formed at the bottom ends of the two sets of mounting blocks 6, and the guiding grooves inside the card slots 12 are the same as the guiding grooves at the top end of the clamping block 14.

[0029] In this embodiment, by driving the cylinder 13 to drive the clamping block 14 to slide along the chute 15 so that the top end of the clamping block 14 is inserted into the card slot 12, the mounting block 6 is prevented from flipping. When it is not necessary to flip, the clamping block 14 is inserted into the card slot 12, which is beneficial to preventing the left flap 1 and the right flap 2 from flipping due to the misoperation of the staff. When the clamping block 14 moves to the bottom end of the chute 15, the distance between the clamping block 14 and the mounting block 6 is greater than the widths of the left flap 1 and the right flap 3, and the left flap 1 and the right flap 3 can be completely flipped. By driving the hydraulic rod 9 to contract, a set of mounting blocks 6 are driven to rotate, a set of mounting blocks 6 rotating drives the connecting rod 11 to rotate, and the connecting rod 11 rotating drives the other set of mounting blocks 6 to rotate, thereby driving the left flap 1 and the right flap 3 to flip for blanking or being tightly connected.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
