[0002] Sludge treatment is an important issue in the fields of environmental protection and resource utilization. Among the many sludge treatment methods, low-temperature biological drying technology has received widespread attention and application due to its advantages such as low energy consumption and effective preservation of microbial activity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5The present invention provides the following technical solution:
[0026] The sludge low-temperature biological drying control device includes a cabinet 1 and a PLC controller 2. The cabinet 1 is equipped with a placement component 3. The PLC controller 2 is fixedly connected to the front of the placement component 3. The cabinet 1 is equipped with a dust removal component 4, which includes a vacuum cleaner 401.
[0027] The placement component 3 includes a mounting plate 301, which is set inside the cabinet 1 and the PLC controller 2 is fixedly connected to the front side of the mounting plate 301. A movable block 302 is fixedly connected to the right side of the mounting plate 301. A transverse moving groove 5 is opened on the right side inside the cabinet 1. The movable block 302 is slidably connected inside the transverse moving groove 5. A pull rod 303 passes through the inside of the transverse moving groove 5. The rear side of the pull rod 303 is fixedly connected to the front side of the movable block 302. An elastic element 304 is sleeved on the surface of the pull rod 303. The two ends of the elastic element 304 are fixedly connected to the movable block 302 and the transverse moving groove 5, respectively. A plurality of positioning holes 305 are evenly opened on the top of the pull rod 303. A positioning pin 6 is inserted into the inside of the positioning hole 305.
[0028] In this embodiment: By setting the placement component 3, the mounting plate 301 provides a stable mounting platform for the PLC controller 2, ensuring that the PLC controller 2 maintains a fixed position during device operation and avoiding its normal operation due to shaking or displacement. The movable block 302 fixedly connected to the right side of the mounting plate 301 can be slidably connected to the transverse moving slot 5 opened on the right side inside the cabinet 1. This structural design allows the mounting plate 301 to slide along the transverse moving slot 5, providing the possibility of transverse movement for the PLC controller 2. This facilitates moving the PLC controller 2 to a suitable position during debugging, maintenance, or repair, making it easier to operate. By pulling the pull rod 303, the movable block 302 can be moved to slide within the transverse moving slot 5, thereby realizing the connection between the mounting plate 301 and the PLC controller. The lateral movement of device 2 allows the operator to easily pull the PLC controller 2 out or push it back into the cabinet 1 according to actual needs. When the pull rod 303 is pulled to move the mounting plate 301, the elastic element 304 is compressed or stretched, which plays a buffering role, reduces the impact force during the movement, and protects the device structure. When the pull rod 303 is released, the elastic restoring force of the elastic element 304 can return the mounting plate 301 and the PLC controller 2 to the initial position, realizing the automatic reset function. By inserting the positioning pin 6 into the positioning hole 305, the pull rod 303 and the moving block 302 can be fixed in a specific position, so that the mounting plate 301 and the PLC controller 2 can be fixed in the required lateral position, which can ensure that the position of the PLC controller 2 is stable when the operator operates it and will not move arbitrarily.
[0029] Specifically, such as Figure 1 , Figure 5As shown, the vacuum cleaner 401 is fixedly connected to the left side of the cabinet 1. The vacuum cleaner 401 has a corrugated pipe 402 fixedly connected to its suction end. The corrugated pipe 402 passes through the cabinet 1 and is movably connected to it.
[0030] Specifically, such as Figure 5 As shown, the end of the corrugated pipe 402 away from the vacuum cleaner 401 is fixedly connected to a horizontal pipe 403, and the side of the horizontal pipe 403 near the PLC controller 2 is fixedly connected to a suction nozzle 404. The number of suction nozzles 404 is set to multiple and evenly distributed.
[0031] Specifically, such as Figure 3 As shown, an extension box 7 is fixedly connected to the top of the cabinet 1. Both the extension box 7 and the cabinet 1 have through holes 8 on their opposite sides, and the horizontal tube 403 is movably connected inside the through hole 8.
[0032] In this embodiment: With the above configuration, the vacuum cleaner 401 generates powerful suction through the operation of its internal motor. The corrugated pipe 402 acts as a bridge connecting the vacuum cleaner 401 and the horizontal pipe 403, allowing the suction generated by the vacuum cleaner 401 to be transmitted to the horizontal pipe 403 and the suction nozzles 404, ensuring the connectivity of the entire vacuuming assembly. Because the corrugated pipe 402 has good flexibility and extensibility, and penetrates the cabinet 1 and is movably connected to it, the horizontal pipe 403 can move and adjust its position freely within a certain range without being restricted by the fixed position of the vacuum cleaner 401. This facilitates cleaning dust from different locations inside the cabinet 1. The horizontal pipe 403 can evenly distribute the suction power transmitted from the corrugated pipe 402 to each suction nozzle 404, allowing multiple suction nozzles 404 to work simultaneously, expanding the vacuuming range. The suction nozzle 404 is the component that comes into direct contact with dust. Multiple evenly distributed suction nozzles 404 increase the dust coverage area, enabling more comprehensive collection of dust inside the cabinet 1, especially around the PLC controller 2. The dust is then concentrated and sucked into the horizontal tube 403, and then sucked away by the vacuum cleaner 401 through the corrugated tube 402. The extension box 7 provides additional space for the movement of the horizontal tube 403. When the horizontal tube 403 moves vertically, the extension box 7 can accommodate part of the length of the horizontal tube 403, avoiding the limitation of the movement range of the horizontal tube 403 due to insufficient space. This ensures that the horizontal tube 403 can flexibly adjust its position to adapt to different dust collection needs. The through hole 8 provides a channel for the vertical movement of the horizontal tube 403, ensuring that the horizontal tube 403 can move smoothly between the extension box 7 and the cabinet 1, realizing the cleaning of dust at different heights.
[0033] Specifically, such as Figure 2 , Figure 3As shown, vertical moving slots 9 are provided on both sides of the inner wall of the extension box 7 and the cabinet 1. The inside of the right vertical moving slot 9 is rotatably connected to a screw 10 through a bearing, and a servo motor 11 is fixedly connected to the top of the screw 10. A screw sleeve 12 is threadedly connected to the surface of the screw 10.
[0034] Specifically, such as Figure 3 As shown, a limiting rod 13 is fixedly connected inside the vertical moving groove 9 on the left side. A connecting frame 15 is fixedly connected to the opposite side of the limiting block 14 and the screw sleeve 12, and the two connecting frames 15 are fixedly connected to both sides of the horizontal tube 403 respectively.
[0035] In this embodiment: Through the above settings, the vertical moving groove 9 provides precise guidance for the vertical movement of the horizontal tube 403, constraining the movement trajectory of the horizontal tube 403 so that it can only move in the vertical direction. When the servo motor 11 starts, the screw 10 starts to rotate, which can convert the rotational motion into linear motion, thereby driving the threaded sleeve 12 connected to the screw 10 to move vertically. The servo motor 11 has high-precision control characteristics and can accurately control the moving distance of the threaded sleeve 12 and the horizontal tube 403, realizing precise adjustment of the position of the horizontal tube 403, so that the dust suction nozzle 4... 04 can accurately align with the area that needs vacuuming. The limiting rod 13 and the limiting block 14 that slides on its surface can provide stable guidance for the movement of the horizontal tube 403. The limiting block 14 restricts the lateral swing of the horizontal tube 403 during the movement, ensuring that the horizontal tube 403 can move up and down smoothly and steadily, avoiding the vacuuming effect caused by shaking. The function of the connecting frame 15 is to firmly connect the limiting block 14, the screw sleeve 12 and the horizontal tube 403 together, making them a whole, and ensuring that when the screw 10 rotates, it can synchronously drive the horizontal tube 403 to move up and down.
[0036] Specifically, such as Figure 1 , Figure 4 As shown, a T-shaped groove 16 is provided on the left side of the inner wall of the cabinet 1. A T-shaped block 17 is slidably connected inside the T-shaped groove 16. The T-shaped block 17 is slidably connected inside the T-shaped groove 16 and is fixedly connected to the left side of the mounting plate 301.
[0037] Specifically, such as Figure 2 As shown, a round block 18 is fixedly connected to the outer side of the pull rod 303, and a cabinet door 19 is rotatably connected to the front side of the cabinet body 1. A circular groove 20 that cooperates with the round block 18 is opened on the inner side of the cabinet door 19.
[0038] In this embodiment: Through the above settings, the T-slot 16 provides a precise sliding track for the T-block 17, so that the mounting plate 301 can only move horizontally along the direction of the T-slot 16, ensuring that the movement path of the mounting plate 301 is accurate, thereby ensuring that the PLC controller 2 can accurately reach the preset position and achieve precise installation and positioning. When the cabinet door 19 is closed, the round block 18 on the pull rod 303 will be embedded in the round groove 20 on the inner side of the cabinet door 19, forming a locking mechanism to fix the mounting plate 301 inside the cabinet 1. This can prevent the mounting plate 301 and the PLC controller 2 from moving accidentally due to vibration, collision or other reasons during equipment operation, ensuring that the PLC controller 2 can work stably.
[0039] Working Principle: During the low-temperature biological drying process of sludge, the PLC controller 2 can precisely control the relevant parameters of the drying equipment according to the preset program and the data fed back by the sensors, ensuring that the drying process is stable and efficient. When it is necessary to inspect and maintain the PLC controller 2 inside the cabinet 1, open the cabinet door 19 and pull the pull rod 303 outward. The pull rod 303 will drive the moving block 302 to slide in the transverse moving groove 5. At the same time, the elastic element 304 will be pulled and compressed. When the moving block 302 moves to the appropriate position, insert the positioning pin 6 into the positioning hole 305 at the corresponding position on the top of the pull rod 303, thereby fixing the position of the moving block 302 and realizing the adjustment of the position of the mounting plate 301. Then, the PLC controller 2 can be inspected and maintained. 2. When cleaning the surface dust, start the vacuum cleaner 401. The vacuum cleaner 401 generates suction that enters the horizontal tube 403 through the corrugated pipe 402. The horizontal tube 403 then evenly distributes the suction from the corrugated pipe 402 to each suction nozzle 404. The multiple suction nozzles 404 can suck up the dust inside the cabinet 1, especially the dust around the PLC controller 2, to prevent the dust from damaging the PLC controller 2 and other electronic components. At the same time, start the servo motor 11. The servo motor 11 will drive the screw 10 to rotate. When the screw 10 rotates, it will drive the screw sleeve 12 to move up and down in the vertical moving groove 9 on the right side. The screw sleeve 12 will drive the horizontal tube 403 and the suction nozzles 404 to move up and down together through the connecting bracket 15 to adapt to the dust collection needs at different heights.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
