Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sludge conveying equipment, specifically relating to a viscous sludge anti-adhesion pushing device. Background Technology
[0002] In sludge treatment processes, large quantities of sludge are often transferred from wide-mouth sludge conveying equipment (such as wide belt conveyors and large screw conveyors) to narrow-mouth sludge conveying equipment (such as small screw conveyors and pipeline conveying equipment) for further processing. The connection between the two is usually a chute. However, sludge (especially municipal sludge and chemical sludge) has strong viscosity and easily adheres to the surface of the inclined plate of the chute when transported by chute. As the amount of adhesion increases, the sludge will form a "bridge" in the chute (that is, the sludge accumulates in an arch shape in the chute, blocking the conveying channel).
[0003] The above problems will lead to the following drawbacks:
[0004] 1. Manual unblocking is labor-intensive: It requires frequent deployment of staff to the site to clean the sludge adhering to the chute with tools. This is not only labor-intensive, but also requires pausing the production line during the unblocking process, which affects processing efficiency.
[0005] 2. Unstable operation of the production line: Blockage of the chute will cause sludge to accumulate in the wide-mouth conveyor and interruption of feeding in the narrow-mouth conveyor, resulting in frequent start-ups and shutdowns of the entire production line and reducing processing capacity;
[0006] 3. Odor diffusion: During the unblocking process, the chute or equipment cover needs to be opened, and the odor generated by the sludge (containing harmful gases such as hydrogen sulfide and ammonia) will diffuse into the workshop, polluting the working environment and endangering the health of the staff. Utility Model Content
[0007] The main purpose of this utility model is to provide a viscous sludge anti-adhesion feeding device, which overcomes the defect of viscous sludge adhesion and bridging caused by the use of chutes in the connection section of the wide-mouth and narrow-mouth sludge conveying equipment in the prior art. It solves the problem of adhesion and bridging of viscous sludge in the connection section, reduces the amount of manual cleaning work, ensures stable operation of the production line, and avoids the spread of odor.
[0008] To achieve the above objectives, this utility model provides a viscous sludge anti-adhesion feeding device, comprising a tank, a drive module, and a reversing module, wherein the drive module and the reversing module are both installed in the tank, wherein:
[0009] The trough is installed in the chute connection section between the wide-mouth sludge conveying equipment and the narrow-mouth sludge conveying equipment; the inner wall of the first side of the trough is provided with a first roller guide rail and a first reversing plate hanger, and the inner side of the first roller guide rail (i.e., the direction away from the inner wall of the first side) is provided with a first push plate guide rail; the inner wall of the second side of the trough is provided with a second roller guide rail and a second reversing plate hanger, and the inner side of the second roller guide rail (i.e., the direction away from the inner wall of the second side) is provided with a second push plate guide rail.
[0010] The drive module includes a cylinder, a connecting rod, a first roller, a second roller, and a flip-up push plate. The cylinder is externally mounted on the side of the groove away from the sliding groove connection section. The connecting rod is built into the groove, and the first roller and the second roller are respectively mounted at both ends of the connecting rod. The first roller is located on the first roller guide rail, and the second roller is located on the second roller guide rail. The drive end of the cylinder (through the groove) is connected to the middle of the connecting rod. The back of the push plate is movably mounted on the connecting rod (and located between the first roller and the second roller).
[0011] The reversing module is located on the side of the groove near the sliding groove connection section, and includes a first reversing plate and a second reversing plate. The tail end of the first reversing plate is hinged to one end of the first push plate guide rail and the front end of the first reversing plate is hung on the first reversing plate hanging rod. The tail end of the second reversing plate is hinged to one end of the second push plate guide rail and the front end of the second reversing plate is hung on the second reversing plate hanging rod.
[0012] As a further preferred embodiment of the above technical solution, the first roller guide rail, the second roller guide rail, the first push plate guide rail, and the second push plate guide rail all extend along the length direction of the groove, the first push plate guide rail is shorter than the first roller guide rail, and the second push plate guide rail is shorter than the second roller guide rail.
[0013] As a further preferred embodiment of the above technical solution, a first touch plate and a second touch plate extend from both sides of the push plate, respectively. The height of the first touch plate is lower than that of the first reversing plate hanger, and the height of the second touch plate is lower than that of the second reversing plate hanger.
[0014] As a further preferred embodiment of the above technical solution, the front end height of the first reversing plate is lower than that of the first touch plate, and the front end height of the second reversing plate is lower than that of the second touch plate.
[0015] As a further preferred technical solution to the above technical solution, the interior of the tank and the front part of the pusher plate (i.e. the pusher surface) are both provided with polytetrafluoroethylene lining plates (to reduce the adhesion of sticky sludge).
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. Completely solve the problem of adhesion and bridging: Through the dual design of PTFE lining to prevent adhesion and automatic pushing, on the one hand, the adhesion force between sludge and tank and push plate is greatly reduced, and on the other hand, the sludge in the tank is directly sent into the narrow-mouth equipment through the periodic pushing of the push plate, which fundamentally avoids the adhesion and bridging of sticky sludge in the connection section, eliminating the need for frequent manual cleaning.
[0018] 2. Ensure stable operation of the production line: The device adopts a reliable structure driven by cylinders and guided by guide rails. With the help of the electrical control system, it can realize fully automatic timed pushing (the pushing cycle can be adjusted according to the amount and viscosity of sludge), ensuring that the sludge output from the wide-mouth equipment can be continuously and stably transported to the narrow-mouth equipment, avoiding frequent start-ups and shutdowns of the production line due to blockage, and improving the overall processing efficiency.
[0019] 3. Compact and reliable structural design: The collaborative design of the drive module and the reversing module realizes the state transition of vertical pushing and horizontal retraction of the push plate. During the retraction process, the push plate does not scrape the sludge in the tank, avoiding secondary adhesion. At the same time, the sliding fit between the roller and the guide rail, and the size matching between the touch plate and the reversing plate, ensure that the device operates without jamming or collision and has a long service life.
[0020] 4. Improved working environment: The PTFE lining of the tank and push plate reduces sludge adhesion, eliminating the need for frequent tank cleaning and significantly reducing the diffusion of odorous gases; moreover, the overall operation of the device is highly automated, reducing the contact time between workers and the odorous environment and improving the workshop working environment.

[0031] In the embodiments of this utility model, those skilled in the art will note that the wide-mouth sludge conveying equipment and narrow-mouth sludge conveying equipment involved in this utility model can be regarded as prior art.
[0032] Preferred embodiment.
[0033] like Figure 1-3 As shown, this utility model discloses a viscous sludge anti-adhesion feeding device, including a tank 1, a drive module 2, and a reversing module 3. Both the drive module 2 and the reversing module 3 are installed in the tank 1, wherein:
[0034] The trough 1 is installed in the chute connection section 6 between the wide-mouth sludge conveying device 4 and the narrow-mouth sludge conveying device 5; the inner wall of the first side of the trough 1 is provided with a first roller guide rail 111 and a first reversing plate hanging rod 112, and the inner side of the first roller guide rail 111 (i.e., the direction away from the inner wall of the first side) is provided with a first push plate guide rail 113; the inner wall of the second side of the trough 1 is provided with a second roller guide rail 121 and a second reversing plate hanging rod 122, and the inner side of the second roller guide rail 121 (i.e., the direction away from the inner wall of the second side) is provided with a second push plate guide rail 123.
[0035] The drive module 2 includes a cylinder 21, a connecting rod 22, a first roller 23, a second roller 24, and a flip-up push plate 25. The cylinder 21 is externally mounted on the side of the groove 1 away from the sliding groove connecting section 6. The connecting rod 22 is built into the groove 1, and the first roller 23 and the second roller 24 are respectively mounted at both ends of the connecting rod 22. The first roller 23 is located on the first roller guide rail 111, and the second roller 24 is located on the second roller guide rail 121. The drive end of the cylinder 21 (through the groove) is connected to the middle of the connecting rod 22. The back of the push plate 25 is movably mounted on the connecting rod 22 (and located between the first roller and the second roller).
[0036] The reversing module 3 is disposed on the side of the groove 1 near the slide joint section 6, and includes a first reversing plate 31 and a second reversing plate 32. The tail end of the first reversing plate 31 is hinged to one end of the first push plate guide rail 113 and the front end of the first reversing plate 31 is hung on the first reversing plate hanging rod 112. The tail end of the second reversing plate 32 is hinged to one end of the second push plate guide rail 123 and the front end of the second reversing plate 32 is hung on the second reversing plate hanging rod 122.
[0037] Specifically, the first roller guide rail 111, the second roller guide rail 121, the first push plate guide rail 113, and the second push plate guide rail 123 all extend along the length direction of the groove 1. The first push plate guide rail 113 is shorter than the first roller guide rail 111, and the second push plate guide rail 123 is shorter than the second roller guide rail 121.
[0038] More specifically, a first touch plate 251 and a second touch plate 252 extend from both sides of the push plate 25, respectively. The height of the first touch plate 251 is lower than that of the first reversing plate hanger 112, and the height of the second touch plate 252 is lower than that of the second reversing plate hanger 122.
[0039] Furthermore, the front end height of the first reversing plate 31 is lower than that of the first touch plate 251, and the front end height of the second reversing plate 32 is lower than that of the second touch plate 252.
[0040] Furthermore, the interior of the tank 1 and the front part (i.e. the pushing surface) of the pusher plate 25 are both provided with polytetrafluoroethylene lining plates 13 (to reduce the adhesion of sticky sludge).
[0041] Regarding this utility model:
[0042] This device, through the coordinated operation of the drive module and the reversing module, completes a cyclical workflow of "pushing sludge - pushing plate retracting - resetting and waiting," with the specific steps as follows:
[0043] (1) Initial state (standby state), such as Figure 4As shown:
[0044] At this time, the cylinder is in a retracted state, and the drive module is located at the end of the tank away from the chute connection section; the push plate is in a vertical state under its own gravity (the pushing surface faces the chute connection section); the front end of the first reversing plate is hung on the first reversing plate hanging rod, the front end of the second reversing plate is hung on the second reversing plate hanging rod, and the reversing module is in an initial standby state; the sludge output from the wide-mouth sludge conveying equipment enters the tank and accumulates in front of the push plate.
[0045] (2) Sludge pushing stage (advance process), such as Figure 5 As shown:
[0046] When the electronic control system (configurable with timers and limit switches for automatic timed pushing) sends a forward signal, the cylinder piston rod extends, pushing the connecting rod to slide along the first and second roller guides towards the chute connection section. The connecting rod drives the push plate forward synchronously. During the forward movement of the push plate, the first and second contact plates on both sides contact the front ends of the first and second reversing plates respectively, applying a forward thrust. Under the action of the thrust, the front end of the first reversing plate disengages from the first reversing plate hanging rod and flips upward around the tail hinge. The second reversing plate flips synchronously, making way for the push plate to advance. The push plate continues to advance, and its pushing surface pushes the viscous sludge in the tank towards the narrow-mouth sludge conveying equipment until the cylinder piston rod extends to its maximum stroke (which can be limited by a limit switch). At this point, the sludge is completely pushed to the feed inlet of the narrow-mouth equipment, and the pushing stage is completed. At this time, the first / second contact plates disengage from the first / second reversing plates, allowing the front ends of the first / second reversing plates to reattach to the first / second reversing plate hanging rod.
[0047] (3) Push plate retraction stage (reverse retraction process), such as Figure 6-7 As shown:
[0048] After the push is completed, the electronic control system sends a retraction signal, the cylinder piston rod retracts, and the connecting rod retracts along the guide rail to the initial position; the push plate retracts synchronously with the connecting rod. When the first and second contact plates on both sides of the push plate contact the front ends of the first and second reversing plates respectively, since the front ends of the reversing plates are hooked on the hanging rod and cannot move backward, the push plate, under the combined action of the retraction force and the reversing plate's blocking force, rotates upward around the back hinge axis; as the connecting rod continues to retract, the push plate gradually changes from a vertical state to a near-water position. In the flat state, the pushing surface faces upward to prevent the push plate from scraping the sludge at the bottom of the tank during the retraction process. At the same time, the contact plates on both sides of the push plate slide along the surface of the reversing plate, driving the push plate into the first push plate guide rail and the second push plate guide rail. The guide rail guides the push plate to maintain a horizontal state and continue to retract. When the push plate retracts to the initial position (the cylinder piston rod is fully retracted), the push plate disengages from the push plate guide rail and, under its own gravity, flips around the hinge axis to reset to a vertical state, waiting for the next push command. This completes one work cycle.
