Specific implementation

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of protection of the utility model.

[0021] Embodiment 1: please refer to Figures 1-4 A kind of environment-friendly spiral press sludge machine, including machine body 1, drainage groove 11 is set on machine body 1, press chamber 2 is provided with above drainage groove 11, filter screen 21 is provided on press chamber 2, cleaning assembly 4 is provided on the outside of press chamber 2, rotating shaft 41 in cleaning assembly 4 is connected with the output end of motor 3, gear one 43 is fixedly installed on rotating shaft 41, gear one 43 is rotationally arranged in transmission case 42, gear one 43 is meshed with toothed belt 45, gear one 43 is transmissionally connected with gear two 44 by toothed belt 45, gear two 44 is connected with rotating disc 47 by fixed shaft 46, drive rod 471 is fixedly installed on the edge of rotating disc 47, drive rod 471 is slidingly installed in sliding slot 481, sliding slot 481 is set above handle 48, handle 48 is rotationally installed on rotating shaft 41, handle 48 is connected with cleaning frame 49 by connecting bolt 492 in the bottom, cleaning brush 491 is provided on cleaning frame 49, cleaning brush 491 is attached to filter screen 21.

[0022] Specifically, the motor 3 drives the rotating shaft 41 to rotate, and the gear one 43 fixed on the rotating shaft 41 rotates accordingly, drives the gear two 44 to rotate through the toothed belt 45, and then drives the rotating disc 47 to rotate. When the driving rod 471 at the edge of the rotating disc 47 is in circular motion, it will slide relatively in the sliding groove 481 and push the handle 48 to swing around the rotating shaft 41. Since the bottom of the handle 48 is connected to the cleaning frame 49 through the connecting bolt 492, and the cleaning brush 491 is arranged on the cleaning frame 49, the swinging of the handle 48 will drive the cleaning frame 49 and the cleaning brush 491 to swing around the rotating shaft 41, thereby realizing the reciprocating cleaning action of the cleaning brush 491 on the surface of the filter screen 21 and achieving the purpose of cleaning the filter screen 21.

[0023] The cleaning frame 49 is installed by the connecting bolt 492, which can be conveniently disassembled from the handle 48 when the cleaning brush 491 needs to be replaced, thereby improving the maintainability of the equipment.

[0024] The cleaning brush 491 closely contacts the filter screen 21, and the bristles can penetrate into the mesh holes and surface textures of the filter screen 21 during the swinging process, thereby thoroughly removing the sludge and impurities attached thereto. The close contact design ensures that there is enough friction between the cleaning brush 491 and the filter screen 21, which can effectively sweep away stubborn impurities without missing or failing to remove impurities due to insufficient contact, thereby further ensuring the thoroughness of cleaning. Meanwhile, the gear one 43 fixed on the rotating shaft 41 drives the cleaning brush 491 to realize periodic swinging cleaning. When the sludge is being pressed, the cleaning brush 491 can simultaneously perform cleaning work. Periodic swinging cleaning can timely remove impurities before they form a blockage, thereby keeping the filter screen 21 in a relatively clean state and ensuring the stable operation and complete cleaning effect of the equipment.

[0025] In example 2, to realize the pressing work of the sludge, please refer to Figures 1-4 On the basis of example 1, the rotating shaft 41 is connected to the screw rod 22, the other end of the screw rod 22 is rotatably installed in the discharge box 6, and the pressing cavity 2 is in communication with the discharge box 6.

[0026] The diameter of the screw rod 22 gradually increases from one end of the rotating shaft 41 to the other end of the discharge box 6, and the edge of the screw on the screw rod 22 closely contacts the inner wall of the pressing cavity 2.

[0027] The feeding box 5 is fixedly installed above the end of the pressing cavity 2 away from the discharge box 6, and the bottom of the feeding box 5 is in communication with the pressing cavity 2.

[0028] The inner wall of the drainage groove 11 is arc-shaped, and the bottom of the inner wall of the drainage groove 11 is provided with a slot 12 in communication with the drainage pipe 13.

[0029] Specifically, the motor 3 drives the rotating shaft 41 to rotate, and since the rotating shaft 41 is connected with the screw rod 22, the screw rod 22 also rotates. After the sludge enters the pressing cavity 2 from the feeding box 5, the spiral blades on the screw rod 22 push the sludge to move towards the discharge box 6. As the diameter of the screw rod 22 gradually increases from one end of the rotating shaft 41 to the other end of the discharge box 6, the space between the spiral blades gradually decreases, forming a gradually increasing extrusion effect on the sludge, thereby extruding the water in the sludge and realizing the pressing dewatering of the sludge;

[0030] The edge of the spiral on the screw rod 22 is in close contact with the inner wall of the pressing cavity 2, so that the sludge is subjected to double extrusion from the screw rod 22 and the inner wall of the pressing cavity 2 during the process of being pushed forward by the screw rod 22, further improving the pressing effect. At the same time, the shape and size of the pressing cavity 2 are matched with the screw rod 22, which can effectively limit the flow range of the sludge and ensure that the sludge is subjected to sufficient pressing force in the pressing cavity 2, thereby better realizing the separation of the sludge and water;

[0031] During the pressing process, the extruded water is discharged through the drainage groove 11 below the pressing cavity 2. The inner wall of the drainage groove 11 is arc-shaped, which is conducive to the gathering and flow of water, so that it can flow more smoothly to the slot 12 and be discharged outside the equipment through the drain pipe 13, and the sludge is discharged through the discharge box 6;

[0032] During the process of driving the sludge to be pressed by the rotating shaft 41, the cleaning assembly 4 simultaneously performs cleaning work, without the need for additional arrangement of time for separate cleaning operation, realizing the simultaneous performance of sludge pressing and cleaning of the filter screen 21, improving the energy utilization efficiency, and reducing energy consumption and operating cost.

[0033] Working principle: when the device is in use, the motor 3 drives the rotating shaft 41 to rotate, driving the screw rod 22 to rotate. After the sludge enters the pressing cavity 2 from the feeding box 5, the spiral blades of the screw rod 22 push the sludge to move towards the discharge box 6. Due to the change in diameter of the screw rod 22, the space between the spiral blades decreases, producing a gradually increasing extrusion on the sludge, extruding the water and realizing the pressing dewatering. The water is gathered through the arc-shaped drainage groove 11, discharged through the slot 12 and the drain pipe 13, and the sludge is discharged from the discharge box 6;

[0034] In the process, the gear one 43 on the shaft 41 rotates in the transmission box 42, the gear one 43 is engaged with the toothed belt 45, drives the gear two 44 through the toothed belt 45, the gear two 44 is connected with the rotating disc 47 through the fixed shaft 46. The driving rod 471 on the edge of the rotating disc 47 does the circular motion and slides in the chute 481 above the rotating handle 48, pushes the rotating handle 48 to swing around the rotating shaft 41, the bottom of the rotating handle 48 is connected with the cleaning frame 49 through the connecting bolt 492, the cleaning brush 491 on the cleaning frame 49 is attached to the filter screen 21, swings along with the rotating handle 48 and reciprocates on the surface of the filter screen 21, and the pressing and cleaning are synchronized, so that the energy utilization efficiency is improved, the energy consumption and operating cost are reduced.
