Description

Technical Field

[0001] This utility model belongs to the field of sludge treatment, specifically an automatic sludge collection device. Background Technology

[0002] Among numerous sludge treatment processes, such as aerobic fermentation (composting), solar drying, and thermal drying, a crucial pretreatment or intermediate treatment step is required—sludge spreading. The purpose of spreading is to evenly and uniformly spread the centrally stored sludge onto a designated site or treatment bed. Its uniformity and looseness directly determine the efficiency and effectiveness of subsequent ventilation, sunlight, microbial fermentation, or heat exchange. It is a fundamental operation that affects the success or failure and efficiency of the entire treatment process. After spreading, the dried sludge needs to be collected and processed.

[0003] Currently, in small and medium-sized treatment plants or under specific working conditions, the common methods of sludge collection are still relatively traditional. In some cases, manual collection is carried out using tools such as shovels. This method is not only labor-intensive and extremely inefficient, but if belt conveyor is used, the existing conveyor belts usually have fixed installations for the cleaning scrapers during the conveying process. The height of the cleaning components and the surface of the conveyor belt is difficult to adjust, resulting in the contact pressure between the scraper and the belt being unadjustable. This affects the cleaning effect of the device, and over time, a large amount of sludge will accumulate on the conveyor belt, affecting the belt's operating power and causing great inconvenience.

[0004] To address the problems raised in the background art, those skilled in the art have proposed an automatic sludge collection device. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic sludge collection device, which solves the technical problems of poor cleaning effect and low equipment maintenance efficiency caused by the fixed installation of cleaning scrapers in existing sludge conveying devices, resulting in unadjustable contact pressure and inconvenient replacement after wear.

[0006] An automatic sludge collection device includes a mounting frame and a fixed frame. Movable modules are provided on both sides of the mounting frame. Mounting blocks are fixedly installed on the side walls of the mounting frame. Rotating rods are rotatably arranged between the opposite side walls of the mounting blocks. Spiral collecting plates are fixedly installed on the outer surface of the rotating rods.

[0009] Preferably, the lifting component includes a driving component fixedly installed on the upper side of the lifting frame, a threaded rod fixedly installed at the output end of the driving component, and sliding grooves are provided on both sides of the lifting frame. One end of the lifting plate extends into one side of the sliding groove and is threadedly connected to the threaded rod.

[0010] Preferably, a limit rod is fixedly installed between the inner walls of the other side of the lifting frame, and the other end of the lifting plate extends into the sliding groove on the other side, with the lifting plate passing through the limit rod and sliding therewith.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 3 As shown: This utility model provides an automatic sludge collection device, including a mounting frame 1 and a fixed frame 2. Movable modules are provided on both sides of the mounting frame 1. The mounting frame 1 serves as the main support structure for the entire collection section. The movable modules (such as pulleys or guide rails) on both sides enable the collection device to move, allowing adjustment of the collection position as needed to flexibly adapt to different working scenarios. Mounting blocks 3 are fixedly mounted on the side walls of the mounting frame 1. A rotating rod 4 is rotatably mounted between the opposite side walls of the mounting blocks 3. A spiral collecting plate 5 is fixedly mounted on the outer surface of the rotating rod 4. A power module for driving the spiral collecting plate 5 to rotate is provided on the upper side of the mounting blocks 3. The mounting blocks 3, rotating rod 4, and spiral collecting plate 5 together constitute the core collection mechanism. The mounting blocks 3 are fixed to the mounting frame 1 to support the rotating rod 4. The power module drives the rotating rod 4 to rotate, which in turn drives the spiral collecting plate 5 fixed on it to rotate. The spiral collecting plate 5, through its unique spiral curved surface, can smoothly and continuously push and unload the accumulated sludge onto the conveyor belt 6, realizing automatic and uniform material collection and avoiding material accumulation and blockage.

[0026] A conveyor belt 6 is slidably mounted between the opposite sidewalls of the fixed frame 2. The conveyor belt 6 is located below one end of the spiral receiving plate 5. The conveyor belt 6 is driven by a drive module installed inside the fixed frame 2. A scraper for cleaning the conveyor belt 6 is rotatably mounted on the upper side of the fixed frame 2. The fixed frame 2 is the main support structure for the conveying section. As the core load-bearing and transmission component, the conveyor belt 6 is responsible for receiving the sludge unloaded from the spiral receiving plate 5 and horizontally transporting it to the designated collection point. The drive module provides the power for the belt's operation.

[0027] Furthermore, the scraping component includes a lifting frame 7 rotatably mounted on the upper side of the fixed frame 2. In the initial state, when cleaning is not required, the lifting frame 7 is located on the side of the fixed frame 2. Locking bolts 8 are threaded on both sides of the lifting frame 7. The locking bolts 8 penetrate the side wall of the lifting frame 7 and are threadedly connected to the fixed frame 2. The lifting frame 7 is adjustablely connected to the fixed frame 2 through the locking bolts 8. Loosening the locking bolts 8 allows the entire lifting frame 7 to rotate around its rotation point, thereby macroscopically adjusting the angle and approximate position of the cleaning component 23 relative to the conveyor belt 6. Tightening the bolts fixes the component, achieving initial coarse adjustment and positioning. A lifting plate 9 is slidably mounted between the opposite side walls of the lifting frame 7 through the lifting component. A plug 10 is fixedly installed on the lower side of the lifting plate 9 through a buckle. The cleaning component 23 is fixedly installed at the lower end of the plug 10.

[0028] As can be seen from the above, when the power module is started, the drive rod 4 and the spiral collecting plate 5 rotate. The rotating spiral collecting plate 5 gathers the sludge in front and pushes it backward, so that the sludge falls evenly onto the continuously running conveyor belt 6 below. The drive module drives the conveyor belt 6 to run, carrying the sludge to move towards its end, and finally transports the sludge to the designated collection point. When it is necessary to clean the conveyor belt 6, the lifting frame 7 is rotated to raise it, and the cleaning component 23 (scraper) keeps in contact with the belt surface to scrape off the residual sludge, ensuring that the belt returns clean and reducing the impact of excessive sludge accumulation on the belt on its movement.

[0029] Example 2: Figure 1 - Figure 5 As shown, based on Embodiment 1, the lifting component includes a drive component 11 fixedly installed on the upper side of the lifting frame 7. The drive component 11 can be a drive motor for driving the threaded rod 12 to rotate. The output end of the drive component 11 is fixedly installed with the threaded rod 12. Slide grooves 13 are provided on both sides of the lifting frame 7. One end of the lifting plate 9 extends into one side slide groove 13 and is threadedly connected to the threaded rod 12. The rotation of the threaded rod 12 drives the lifting plate 9 to rise or fall.

[0030] Furthermore, a limit rod 14 is fixedly installed between the inner walls of the other side of the lifting frame 7, and the other end of the lifting plate 9 extends into the sliding groove 13 on the other side. The lifting plate 9 passes through the limit rod 14 and is slidably set therewith.

[0031] Preferably, the fastener includes mounting grooves 15 on both sides of the insert post 10 and wedge-shaped blocks 16 slidably disposed within the mounting grooves 15. A slot 17 is provided on the lower surface of the lifting plate 9. The insert post 10 is inserted into the slot 17 and slidably disposed therewith. A pressure plate 18 is slidably disposed on the upper side of the lifting plate 9. A push rod 19 is fixedly disposed at the lower end of the pressure plate 18. One end of the push rod 19 extends into the slot 17 and slidably disposed therewith. The push rod 19 contacts the inclined surface of the wedge-shaped block 16. A compression spring 20 is disposed within the mounting groove 15. Both ends of the compression spring 20 are respectively connected to the wedge-shaped block. The side wall of 16 is connected to the inner side wall of the mounting groove 15. When inserted and locked, under the elastic force of the compression spring 20, the wedge-shaped block 16 pops out and locks into the inner wall of the slot 17 of the lifting plate 9, thereby firmly locking the insert 10 and the cleaning part 23 at its lower end. When the cleaning part 23 needs to be replaced, the pressure plate 18 is pressed down, and the top rod 19 descends accordingly. Using its inclined surface to overcome the force of the compression spring 20, the wedge-shaped block 16 is pressed back into the mounting groove 15, releasing the buckle. At this time, the insert 10 can be pulled out from the slot 17 to complete the disassembly. The whole process does not require tools and is simple and quick.

[0032] Specifically, a return spring 21 is sleeved on the outer surface of the push rod 19. The two ends of the return spring 21 are connected to the side wall of the pressure plate 18 and the upper surface of the lifting plate 9, respectively. The return spring 21 is used to drive the push rod 19 to reset.

[0033] Preferably, a plurality of evenly distributed support rollers 22 are rotatably arranged between the opposite sidewalls of the fixed frame 2. The support rollers 22 are in contact with the conveyor belt 6 and are used to support the conveyor belt 6 to improve its stability.

[0034] As can be seen from the above, if the cleaning effect is found to be poor (too low pressure) or the belt wears too quickly (too high pressure), the drive component 11 of the lifting component can be activated. The drive component 11 drives the threaded rod 12 to rotate, so that the lifting plate 9 rises or falls precisely, thereby moving the entire cleaning component 23 assembly closer to or away from the conveyor belt 6 until the optimal cleaning contact pressure is obtained. After adjustment, the lifting frame 7 can be fixed as a whole by locking bolts 8.

[0035] When the cleaning part 23 wears down to the point of needing replacement, the operator simply needs to manually press down the pressure plate 18. The pressure plate 18 pushes the push rod 19, and the inclined surface of the push rod 19 presses back the wedge-shaped locking block 16, releasing the lock on the insertion post 10. At this point, the insertion post 10 with the old cleaning part 23 can be pulled out of the slot 17 of the lifting plate 9. Then, the insertion post 10 with the new cleaning part 23 is inserted into the slot 17, the pressure plate 18 is released, and under the action of the compression spring 20, the wedge-shaped locking block 16 automatically pops out and locks in place, completing the replacement. The entire process takes very little time, greatly reducing equipment maintenance downtime.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
