Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-4 A filter press includes a frame 1, a mounting base 6 on one side of the frame 1, a feeding pipe fixedly connected inside the frame 1, a fixing groove 7 at the top of the mounting base 6, a screw 8 rotatably connected inside the fixing groove 7, a support base 9 threadedly connected to the outside of the screw 8, a conveying pipe 10 fixedly installed inside the support base 9, a mounting box 16 fixedly connected to the top of the mounting base 6, a conveyor belt 17 inside the mounting box 16, a filter screen 19 fixedly connected to the middle of the conveyor belt 17, and a dust collection box 18 slidably connected inside the mounting box 16 and below the filter screen 19. The conveying pipe 10 is inspected by the operator. During repair or maintenance, the rotation of screw 8 can drive support 9 to slide in fixed groove 7, thereby disengaging conveying pipe 10 from feeding pipe. This allows workers to inspect and maintain conveying pipe 10. During the disengagement process, concrete and liquid at the connection between conveying pipe 10 and feeding pipe will fall into installation box 16. The rotation of filter screen 19 will then facilitate the conveying of concrete, while concrete slurry will fall through filter screen 19 into dust collection box 18. This structure solves the problem of difficult-to-clean-up concrete and liquid, ensuring a cleaner production environment.

[0030] Specifically, both sides of the frame 1 are equipped with vibration components. Each vibration component includes a worm gear 15 rotatably mounted on the outside of the frame 1. A rotating shaft 12 is equidistantly rotatably connected to the outside of the frame 1, and worm wheels 14 are fixedly connected to the outside of each rotating shaft 12. When the slurry inside the filter plate 4 is fully compressed, the operator can activate the drive source at the worm gear 15 to drive it to rotate. This, in turn, drives the rotation of multiple worm wheels 14, which in turn drives the rotation of the rotating shaft 12. This, in turn, causes the corresponding cam 13 to move eccentrically and strike the sliding member 5, causing the filter plate 4 to vibrate slightly. This dislodges the concrete slurry adhering to the filter cloth, facilitating subsequent processing. A cam 13 is fixedly connected to the outside of 12 and to one side of the worm gear 14. The worm gear 14 is meshed with the worm 15. A pressure plate 3 is slidably installed at both ends inside the machine frame 1. Multiple filter plates 4 are provided between the two pressure plates 3. Sliding parts 5 are fixedly connected to both sides of the filter plates 4. The sliding parts 5 overlap the upper part of the machine frame 1. The cam 13 abuts against the corresponding sliding parts 5. A hydraulic cylinder 2 is fixedly installed inside the machine frame 1. By extending and retracting the piston rod of the hydraulic cylinder 2, the multiple filter plates 4 and filter cloth can be squeezed by the pressure plate 3 to achieve the purpose of pressing and filtering concrete. The feeding pipe is fixedly connected to one of the pressure plates 3, and the piston rod of the hydraulic cylinder 2 is fixedly connected to the other pressure plate 3.

[0031] Specifically, a corrugated pipe 11 is fixedly connected to the end of the conveying pipe 10 away from the feeding pipe. The support base 9 is slidably connected to the inner wall of the fixing groove 7. The use of the corrugated pipe 11 facilitates the movement of the conveying pipe 10. A sealing ring is fixedly connected to the end of the conveying pipe 10 away from the corrugated pipe 11. A sealing groove is opened on the side of the feeding pipe near the conveying pipe 10 to cooperate with the sealing ring. The cooperation between the sealing ring and the sealing groove can enhance the sealing performance between the conveying pipe 10 and the feeding pipe, thereby reducing the leakage of concrete slurry. Drive motors b21 are fixedly installed on both sides of the frame 1. The output shafts of drive motors b21 are fixedly connected to the corresponding worm gears 15. Transmission rollers are rotatably installed on both sides of the inner wall of the mounting box 16. The rotation of the two transmission rollers can drive the conveyor belt 17 to run. The conveyor belt 17 is connected between the two transmission rollers. A drive motor a20 is fixedly installed on the outside of the mounting box 16. The output shaft of drive motor a20 is fixedly connected to one of the transmission rollers.

[0032] Working principle: First, the operator can control the hydraulic cylinder 2 to start via an external controller, and then transport concrete to each filter plate 4 through the conveying pipe 10 and the feeding pipe. The squeezing force of the hydraulic cylinder 2 causes adjacent filter plates 4 to squeeze against each other, thereby separating the mud and wastewater. After the mud in the filter plate 4 is compressed, the operator can control the drive motor b21 to start, driving the worm gear 15 to rotate, which in turn drives the rotation of multiple worm wheels 14, and simultaneously drives the rotation of the rotating shaft 12. This causes the corresponding cam 13 to move eccentrically, striking the sliding part 5, causing the filter plate 4 to vibrate slightly, thus shaking off the concrete mud adhering to the filter cloth. When the operator is inspecting or maintaining the conveying pipe 10... The screw 8 can be manually rotated to drive the support base 9 to slide in the fixed groove 7, thereby disengaging the conveying pipe 10 from the feeding pipe. This allows workers to inspect and maintain the conveying pipe 10. The use of the sealing ring and sealing groove enhances the sealing performance between the conveying pipe 10 and the feeding pipe, reducing concrete slurry leakage. During the disengagement process, the concrete and its liquid at the connection between the conveying pipe 10 and the feeding pipe fall into the installation box 16. The rotation of the filter screen 19 facilitates the conveying of concrete, while the concrete slurry falls through the filter screen 19 into the dust collection box 18. This structure solves the problem of cleaning up fallen concrete and its liquid, ensuring a cleaner production environment.
