Description

Technical Field

[0001] The present invention relates to a sedimentation tank, and more specifically, to a sedimentation tank for rubber auxiliary production wastewater with a movable scraper. Background Art

[0002] Rubber auxiliaries are an indispensable type of chemical additive in the rubber industry, and they play a key role in the processing and use of rubber. There are many types of rubber auxiliaries, including accelerators, anti-aging agents, vulcanizing agents, plasticizers, reinforcing fillers, foaming agents, softeners, pigment dispersants, etc. Each auxiliary has its specific function to improve the performance or processability of rubber.

[0003] The wastewater generated during the production of rubber auxiliaries needs to go through the sedimentation and purification process before it can be safely discharged. After the sedimentation tank is frequently used or operated for a long time, a large amount of sediment will accumulate inside it, and regular dredging and maintenance operations are urgently needed. However, traditional scraping equipment relies too much on manual operation, or when the equipment runs inside the sedimentation tank, due to the large size of the sedimentation tank, it is easy to get stuck when the equipment scrapes the entire inner wall of the sedimentation tank. The traditional method is not only inefficient, slow to scrape and easy to get stuck, but also exposes the operators directly to the sedimentation tank containing harmful chemical gases and complex physical environments, seriously threatening the physical and mental health and safety of the staff.

[0004] Based on this, the present invention discloses a sedimentation tank for rubber auxiliary production wastewater with a movable scraper. Summary of the Invention

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. In the sedimentation tank for rubber auxiliaries production wastewater with a movable scraper, through the hydraulic rod and the driving assembly, the driving assembly drives the reciprocating assembly to perform a linear reciprocating motion through the threaded lead screw, which is beneficial to realizing the automatic cyclic action of the sludge scraping assembly, reducing the need for manual intervention, and thus improving the cleaning efficiency; cooperating with the second scraper in the first sludge scraping assembly to cyclically impact the inner wall of the sedimentation tank is beneficial to loosening the stubborn sediment attachment layer, and then facilitating the subsequent scraping operation; among them, the third scraper in the second sludge scraping assembly is in fit with the inner wall of the sedimentation tank, combined with the design of the arc-shaped plate and the torsion spring, which is beneficial to automatically adjust when encountering protrusions or stubborn layers, avoiding jamming, ensuring the continuity and smoothness of the sludge scraping process, and thus effectively coping with various complex situations.

[0029] 2. In the sedimentation tank for rubber auxiliaries production wastewater with a movable scraper, multiple second scrapers are arranged to work side by side, which is beneficial to increasing the scraping area and force. Even if an individual scraper encounters an obstacle, it does not affect the overall operation, thus ensuring the efficiency of the entire scraping process. Secondly, the first spring and the second spring in the lifting assembly can absorb impacts, which is beneficial to reducing the direct collision of the first scraper when encountering hard sediment. Moreover, the multi-section sleeve can optimize the space and ensure that the first scraper always fits the bottom wall of the sedimentation tank during both rising and falling. In addition, the airbag is filled with sediment treatment agent and sprayed through a high-pressure nozzle, which is beneficial to softening and decomposing the sediment, facilitating subsequent physical scraping.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] When the existing settling tank scrapes the sediment, it overly relies on manual labor or the equipment solely depends on scraping during operation, and it is prone to jamming. The traditional method not only has low efficiency but also is likely to affect the physical and mental health of the staff.

[0053] Therefore, the present invention provides a settling tank for rubber auxiliary production wastewater with a movable scraper. Refer to Figure 1 As shown, it includes a settling tank 1. Drain pipes 2 are connected to both sides of the settling tank 1. The sediment and wastewater are discharged through the drain pipes 2 on both sides, and the drain pipes 2 are located at the bottom end of the settling tank 1.

[0054] Specifically, refer to Figure 1 - Figure 2 As shown, a hydraulic rod 3 is arranged at the center of the bottom end of the sedimentation tank 1. A driving assembly 4 is arranged on the hydraulic rod 3, and a number of threaded lead screws 5 are evenly arranged on the driving assembly 4. As Figure 3 can be seen, the driving assembly 4 includes an installation cylinder 41 fixedly connected to the top end of the hydraulic rod 3. A driving motor 42 is fixedly arranged inside the installation cylinder 41. A first bevel gear 43 is arranged at the output end of the driving motor 42. A number of second bevel gears 44 corresponding to the threaded lead screws 5 are meshed with the first bevel gear 43, and the second bevel gears 44 are fixedly connected to one end of the threaded lead screws 5.

[0055] Among them, as Figure 5 and Figure 7 - Figure 8 shown, one end of the threaded lead screw 5 away from the driving assembly 4 is provided with a mounting plate 9. A reciprocating assembly 17 is arranged inside the mounting plate 9. The driving assembly 4 drives the reciprocating assembly 17 to do linear reciprocating motion through the threaded lead screw 5. The reciprocating assembly 17 includes a gear 171 and a moving plate 172. An installation groove 16 is opened at the middle position inside the mounting plate 9. The moving plate 172 is slidably connected inside the installation groove 16. A rectangular through opening 173 is opened in the middle of the moving plate 172. The gear 171 is fixedly connected to the other end of the threaded lead screw 5 away from the second bevel gear 44. The gear 171 is meshed with the top end and the bottom end of the through opening 173, and part of the area of the gear 171 has teeth and part of the area is smooth. In this way, during the rotation of the gear 171, it will cycle and reciprocally mesh with the top end and the bottom end of the rectangular through opening 173 respectively, thereby driving the moving plate 172 to do linear reciprocating motion left and right; it should be added that the entire mechanism includes the threaded lead screw 5, the mounting plate 9 and the reciprocating assembly 17, the first sludge scraping assembly 12, the second sludge scraping assembly 13, etc. The best initial state is to lift to the top of the sedimentation tank 1 to prevent the wastewater from soaking the equipment for a long time. Of course, the equipment can also be placed inside the sedimentation tank 1, but protection work needs to be done well.

[0056] Then a first sliding groove 15 is penetrated and opened at the top end of the installation groove 16 inside the mounting plate 9. As Figure 6 shown, the bottom end of the first sliding groove 15 is of a T-shaped structure. A moving rod 174 adapted to the first sliding groove 15 is slidably connected inside the first sliding groove 15. The moving rod 174 is fixedly connected to the moving plate 172. Figure 8 It can be seen that the center of the moving rod 174 and the center of the gear 171 are on the same vertical line, which can ensure the symmetry of both ends of the moving rod 174 and ensure that both ends move equal distances during linear reciprocating motion; and a number of ejector rods 175 corresponding to the first sludge scraping assembly 12 are fixedly connected to the moving rod 174, and the top end of the ejector rod 175 is of a smooth structure.

[0057] Furthermore, as Figure 2 and Figure 6It can be seen that a number of first sludge scraping components 12 are provided on the mounting plate 9, and a number of second sludge scraping components 13 are provided at the bottom end of the mounting plate 9. The first sludge scraping components 12 are driven by the reciprocating component 17 to repeatedly impact the inner wall of the sedimentation tank 1, so that the stubborn sediment attachment layer loosens, and then the second sludge scraping components 13 are used to scrape the sediment after the impact of the first sludge scraping components 12, so as to achieve the purpose of efficient cleaning.

[0058] Specifically, it can be seen from Figure 9 - Figure 10 As shown, the first sludge scraping component 12 includes a second scraper 121 and a sliding rod 123. A number of second sliding grooves 18 are evenly formed in the mounting plate 9. A sliding cavity 19 is formed in the second sliding groove 18. The sliding cavity 19 is larger than the second sliding groove 18. A sliding rod 123 is slidably connected in the second sliding groove 18. The bottom end of the sliding rod 123 extends outside the second sliding groove 18 and is fixedly connected to a second scraper 121. The second scraper 121 has a wedge-shaped structure, and a number of notches 122 are formed at the narrower end of the second scraper 121. The number of notches 122 can serve the purpose of improving the impact and removing the sediment attachment layer, making it easier to loosen from the inner wall of the sedimentation tank 1.

[0059] Secondly, a limiting ring 125 is fixedly connected to the sliding rod 123. The limiting ring 125 is slidably connected in the sliding cavity 19, and the radius of the limiting ring 125 is larger than the radius of the second sliding groove 18. A third spring 124 is sleeved on the sliding rod 123. One end of the third spring 124 is fixedly connected to the limiting ring 125, and the other end is fixedly connected to a moving ring 126. The moving ring 126 is slidably connected to the sliding rod 123, and the moving ring 126 is fixedly connected to the inner wall of the sliding cavity 19 away from the limiting ring 125. In this way, the sliding rod 123 can slide in the second sliding groove 18, driving the limiting ring 125 to slide in the sliding cavity 19. Under the limiting action of the moving ring 126, the third spring 124 is further compressed. When the third spring 124 is released, the limiting ring 125 restricts the sliding rod 123 to reset to a specified position in contact with the inner wall of the sedimentation tank 1, and then impacts the inner wall of the sedimentation tank 1.

[0060] Then, a third chute 127 is provided at the end of the sliding rod 123 away from the top end of the second scraper 121. The length of the third chute 127 is adapted to the length of the ejector rod 175. A convex block 128 is fixedly provided at the top end of the third chute 127. The convex block 128 has a smooth structure. In this way, both the convex block 128 and the end of the ejector rod 175 have smooth structures, ensuring that when the ejector rod 175 presses against the convex block 128, the sliding rod 123 can slide obliquely upward along the second chute 18. Therefore, both the sliding rod 123 and the corresponding second chute 18 are inclined, so as to drive the narrower end of the second scraper 121 to impact the inner wall of the settling tank 1 in an obliquely downward direction. The oblique impact is more conducive to giving full play to the characteristics of the wedge-shaped structure of the second scraper 121. Coupled with a number of notches 122 provided at the end, it is possible to better shovel off the loosened attached layer, facilitating the subsequent scraping. In addition, it should be noted that several groups of first mud scraping assemblies 12 are provided, and the second scrapers 121 are arranged side by side and fit against the inner wall of the settling tank 1. Firstly, this multi-group side-by-side arrangement can more efficiently remove the loosened attached substances in the reciprocating vibration area. Because if there is only one plate, in practical applications, it is difficult to achieve reciprocating vibration due to its length limitation. With multiple groups, this movement effect can be more easily achieved. Secondly, it is to prevent a certain area of the attached layer from being relatively stubborn or protruding, resulting in the second scraper 121 being stuck or unable to reset. For multiple second scrapers 121, if one of them cannot be reset or is stuck, it does not affect the other second scrapers 121 from impacting and operating on other parallel areas. If it is a single whole piece, a protrusion in a certain place may affect the impact operation in other areas, etc.

[0061] The axial directions of the ejector rod 175 and the sliding rod 123 are parallel, which can ensure that the ejector rod 175 jacks up the sliding rod 123 obliquely. At the same time, there is a clearance between the end of the sliding rod 123 away from the second scraper 121 and the top end of the second chute 18, so as to ensure that the sliding rod 123 has space to slide obliquely upward. In addition, the area of the gear 171 with teeth is adapted to the distance that the moving rod 174 needs to move when the gear 171 drives the ejector rod 175 to jack up the convex block 128 once and then let it fall. In this way, when the gear 171 meshes with the upper and lower ends of the through hole 173 of the moving plate 172 respectively, it can drive the ejector rod 175 to jack up the convex block 128 and let it fall, completing a process of the second scraper 121 impacting the inner wall of the settling tank 1. Through such movement, the reciprocating impact of the second scraper 121 on the inner wall of the settling tank 1 can be realized.

[0062] Further, as Figure 2 and Figure 3As shown in the figure, a lifting assembly 7 is provided on the threaded screw rod 5 on the same side of the drain pipe 2. A first scraper 8 that fits against the inner wall of the bottom end of the sedimentation tank 1 is provided at the bottom end of the lifting assembly 7 for scraping the sediment on the bottom wall. The lifting assembly 7 includes an outer cylinder 71 fixedly connected to the bottom end of the first scraper 8. In the initial state, the first scraper 8 is arranged adjacent to the driving assembly 4. An inner cylinder 72 is slidably connected in the outer cylinder 71. The bottom end of the inner cylinder 72 located inside the outer cylinder 71 is fixedly connected to one end of a first spring 73, and the other end of the first spring 73 is fixedly connected to the inner wall of the bottom end of the outer cylinder 71. The other end of the inner cylinder 72 extends outside the outer cylinder 71, and a telescopic rod 74 is slidably connected in the inner cylinder 72. The bottom end of the telescopic rod 74 located inside the inner cylinder 72 is fixedly connected to one end of a second spring 75, and the other end of the second spring 75 is fixedly connected to the inner wall of the bottom end of the inner cylinder 72. The other end of the telescopic rod 74 extends outside the inner cylinder 72 and is fixedly connected to a pressing block 76. The pressing block 76 is threadedly connected to the threaded screw rod 5. By arranging the inner cylinder 72 to be slidably connected in the outer cylinder 71 and the telescopic rod 74 to be slidably connected in the inner cylinder 72, firstly, it can support the threaded screw rod 5. Secondly, through the elastic forces of the first spring 73 and the second spring 75 in the outer cylinder 71 and the inner cylinder 72, it can exert a squeezing effect on the first scraper 8 to make it fit against the bottom wall of the sedimentation tank 1. Additionally, when the first scraper 8 encounters a hard sediment attachment layer, the first spring 73 and the second spring 75 can play an upward buffering role so that the first scraper 8 will not get stuck. Finally, it can reduce the overall telescopic space, enabling the threaded screw rod 5 to be closer to the bottom wall of the sedimentation tank 1 in the initial state, so that the mounting plate 9 can be closer to the bottom wall of the sedimentation tank 1, enabling it to clean more attachments on the inner wall.

[0063] Furthermore, the second sludge scraping assembly 13 includes an arc-shaped plate 131. A material groove 20 is formed on one side of the mounting plate 9. A mounting rod 21 is fixedly connected in the material groove 20. A plurality of arc-shaped plates 131 corresponding to the second scraper 121 are rotatably connected to the mounting rod 21. A third scraper 132 is fixedly provided at the top end of the arc-shaped plate 131. The third scraper 132 fits against the inner wall of the sedimentation tank 1. The third scraper 132 is made of a soft material, such as rubber, etc. A convex rod 133 is fixedly provided directly below the third scraper 132 at the top end of the arc-shaped plate 131. The top end of the convex rod 133 has a smooth structure. The material of the third scraper 132 should be soft, so that when it encounters a protrusion or a stubborn sediment attachment layer, it can be squeezed and deformed, and then come into contact with the convex rod 133 with a smooth structure, thereby lifting the arc-shaped plate 131, and thus temporarily skipping a certain protrusion, etc. And it should also have a certain hardness so that it can play a scraping role when scraping the ordinary attachment layer and the attachment layer after being impacted by the second scraper 121. Therefore, rubber can achieve this, and other related materials can also be used. Here, only rubber is taken as an example.

[0064] A torsion spring 134 is fixedly installed at the connection between the arc-shaped plate 131 and the mounting rod 21. One end of the torsion spring 134 is fixedly connected to the arc-shaped plate 131, and the other end is fixedly connected to the mounting rod 21. The torsion spring 134 always has a tendency to rotate the arc-shaped plate 131 towards the direction of fitting with the inner wall of the settling tank 1. This can ensure that the third scraper 132 always fits the inner wall of the settling tank 1 to scrape the sediment attachment layer loosened by the impact of the second scraper 121. Secondly, when encountering a stubborn layer or a protrusion locally, under the action of the convex rod 133 with a smooth structure, the arc-shaped plate 131 can be rotated away from the inner wall of the settling tank 1, thus not affecting the operation of other arc-shaped plates 131 driving the third scraper 132. And after passing over the protrusion or the stubborn layer, the arc-shaped plate 131 will be reset to fit the inner wall of the settling tank 1 under the action of the torsion spring 134. After multiple up and down movements and scrapings, the stubborn layer or the protrusion can be gradually scraped off; it should be noted here that the reason for setting several groups of arc-shaped plates 131 corresponding to the second scraper 121 and also arranging them side by side is that when working together with the second scraper 121, when encountering a stubborn layer or a protrusion at the same place, synchronous jumping can be achieved, without affecting the operation of other second scrapers 121 and third scrapers 132.

[0065] There are gaps between both sides of the first scraper 8, the second scraper 121, the third scraper 132 and the convex rod 133 and the inner walls on both sides of the settling tank 1, but close to the inner wall of the settling tank 1. This ensures that when other inner walls around the settling tank 1 are operating simultaneously, the influence is minimized, and as much of the inner wall of the settling tank 1 as possible can be scraped.

[0066] In addition, as shown in Figure 1 - Figure 3 a gas bag 6 is arranged between the extrusion block 76 and the mounting plate 9 on the threaded lead screw 5. The gas bag 6 is sleeved on the threaded lead screw 5, and the gas bag 6 is filled with sediment treatment agent. A chemical addition pipe 10 is arranged above the first sludge scraping assembly 12 on the mounting plate 9. A number of high-pressure nozzles 11 are connected to the chemical addition pipe 10. The chemical addition pipe 10 is connected to the gas bag 6. The sediment treatment agent in the gas bag 6 is sprayed onto the sediment attachment layer on the inner wall of the settling tank 1 through the number of high-pressure nozzles 11.

[0067] In addition, as shown in Figure 4 - Figure 6 a limiting component 14 is fixedly installed on both sides of the mounting plate 9. The limiting component 14 includes limiting plates 141 fixedly connected to both sides of the mounting plate 9. The top ends of the limiting plates 141 are rotatably connected with rollers 142. The rollers 142 are in contact with the inner wall of the settling tank 1. In this way, during the up and down movement of the mounting plate 9, the moving resistance can be reduced, and at the same time, the mounting plate 9 can be limited, so that it cannot rotate and can only move up and down along the inner wall of the settling tank 1.

[0068] Working principle:

[0069] When the sedimentation tank 1 needs to be cleaned, the sediment treatment agent is added into the air bag 6, and the drive motor 42 and the hydraulic rod 3 are started. Then the hydraulic rod 3 rises, and the drive motor 42 drives the movable plate 172 to reciprocate linearly through the threaded screw 5, and then squeezes the protrusion 128 through the top rod 175, so that the slide bar 123 drives the second scraper 121 to cyclically and obliquely hit the inner wall attachment layer of the sedimentation tank 1 downward, causing it to loosen, and then the hydraulic rod 3 continues to rise, and the loose sediment attachment layer is scraped off by the third scraper 132 under the second scraper 121, and the threaded screw 5 rotates to drive the extrusion block 76 to move in the direction of the extrusion air bag 6 to extrude the air bag 6. Because the extrusion block 76 is fixedly connected to the first scraper 8 through the outer cylinder 71, The first scraper 8 limits the extrusion block 76, so that it can only move forward and backward. After the airbag 6 is squeezed, the treatment agent in it is sprayed to the attachment layer through the high-pressure nozzle 11, so that it is separated from the inner wall of the sedimentation tank 1 and loosened, which is convenient for the second scraper 121 and the third scraper 132 to operate. The fallen sediment attachments pass through the arc-shaped arc plate 131, and then slide to the bottom of the sedimentation tank 1 through the material trough 20. The first scraper 8 scrapes the sediment attachments that fall on the bottom into the vicinity of the drain pipe 2 for discharge; thereby achieving the purpose of scraping off the sediment attachment layer on the inner wall of the sedimentation tank 1, and then effectively solving the problem that the existing sedimentation tank 1 relies too much on manual labor when scraping off the sediment, which is inefficient and easy to affect the physical and mental health of the staff.
