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

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Existing sedimentation tanks rely too much on manual labor or equipment scraping alone during operation to scrape sediment, and are prone to getting stuck. The traditional method is not only inefficient but also easily affects the physical and mental health of workers.

[0025] To this end, the present invention provides a settling tank for wastewater from rubber additive production with a movable scraper, see Figure 1 As shown, it includes a sedimentation tank 1, and drainage pipes 2 are connected on both sides of the sedimentation tank 1. The sediment and wastewater are discharged through the drainage pipes 2 on both sides, and the drainage pipes 2 are located at the bottom end of the sedimentation tank 1.

[0026] For details, see 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 plurality of threaded screw rods 5 are evenly arranged on the driving assembly 4, such as Figure 3 It can be seen that the drive assembly 4 includes a mounting cylinder 41 fixedly connected to the top end of the hydraulic rod 3, a drive motor 42 is fixedly arranged in the mounting cylinder 41, a first bevel gear 43 is arranged at the output end of the drive motor 42, a plurality of second bevel gears 44 corresponding to the threaded screw 5 are meshed on the first bevel gear 43, and the second bevel gear 44 is fixedly connected to one end of the threaded screw 5.

[0027] Among them, Figure 5 and Figure 7-Figure 8As shown, a mounting plate 9 is provided at one end of the threaded screw 5 away from the driving assembly 4, and a reciprocating assembly 17 is provided in the mounting plate 9. The driving assembly 4 drives the reciprocating assembly 17 to perform linear reciprocating motion through the threaded screw 5, and the reciprocating assembly 17 includes a gear 171 and a moving plate 172. A mounting groove 16 is provided in the middle position of the mounting plate 9, and the moving plate 172 is slidably connected in the mounting groove 16. A rectangular through-hole 173 is provided in the middle of the moving plate 172. The gear 171 is fixedly connected to the other end of the threaded screw 5 away from the second bevel gear 44, and the gear 171 is aligned with the top and bottom ends of the through-hole 173. The gear 171 is meshed, and some areas of the gear 171 contain teeth, while some areas are smooth. In this way, during the rotation of the gear 171, it will reciprocate and mesh with the top and bottom ends of the rectangular opening 173 respectively, thereby driving the movable plate 172 to reciprocate left and right in a straight line. It should be supplemented that the entire mechanism includes a threaded screw 5, a mounting plate 9 and a reciprocating assembly 17, a first sludge scraping assembly 12 and a second sludge scraping assembly 13 arranged thereon. The initial state is preferably raised to the top of the sedimentation tank 1 to prevent wastewater from soaking the equipment for a long time. Of course, the equipment can also be placed in the sedimentation tank 1, but protective work needs to be done.

[0028] Then, a first slide groove 15 is provided in the mounting plate 9 at the top of the mounting groove 16. Figure 6 As shown, the bottom end of the first slide groove 15 is a T-shaped structure, and a moving rod 174 adapted to the first slide groove 15 is slidably connected in the first slide groove 15, and 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 located on the same vertical line, which can ensure the symmetry of the two ends of the moving rod 174 and ensure that the two ends move equal distances when performing linear reciprocating motion; and a number of top rods 175 corresponding to the first mud scraper assembly 12 are fixedly connected to the moving rod 174, and the top of the top rod 175 is a smooth structure.

[0029] Further, such as Figure 2 and Figure 6 It can be seen that a plurality of first scraper assemblies 12 are arranged on the mounting plate 9, and a plurality of second scraper assemblies 13 are arranged at the bottom end of the mounting plate 9. The first scraper assemblies 12 are driven by the reciprocating assembly 17 to cyclically impact the inner wall of the sedimentation tank 1 to loosen the stubborn sediment attachment layer, and then the second scraper assemblies 13 are used to scrape off the sediment after the impact of the first scraper assemblies 12, so as to achieve the purpose of efficient cleaning.

[0030] For details, please refer to Figure 9-10As shown, the first scraper assembly 12 includes a second scraper 121 and a slide rod 123, a plurality of second slide grooves 18 are evenly opened in the mounting plate 9, a slide cavity 19 is opened in the second slide groove 18, the slide cavity 19 is larger than the second slide groove 18, a slide rod 123 is slidably connected in the second slide groove 18, the bottom end of the slide rod 123 extends to the outside of the second slide groove 18 and is fixedly connected to the second scraper 121, the second scraper 121 is a wedge-shaped structure, and a plurality of notches 122 are opened at the narrower end of the second scraper 121, and the plurality of notches 122 can improve the purpose of impacting and removing the sediment attachment layer, making it easier to loosen from the inner wall of the sedimentation tank 1.

[0031] Secondly, a limit ring 125 is fixedly connected to the slide bar 123, and the limit ring 125 is slidably connected in the slide cavity 19, and the radius of the limit ring 125 is greater than the radius of the second slide groove 18. A third spring 124 is sleeved on the slide bar 123, one end of the third spring 124 is fixedly connected to the limit ring 125, and the other end is fixedly connected to the moving ring 126. The moving ring 126 is slidably connected to the slide bar 123, and the moving ring 126 is fixedly connected to the inner wall of the slide cavity 19 away from the limit ring 125. In this way, the slide bar 123 can slide in the second slide groove 18, driving the limit ring 125 to slide in the slide cavity 19, and under the limiting action of the moving ring 126, the third spring 124 is squeezed. In this way, when the third spring 124 is released, the limit ring 125 limits the slide bar 123 to reset it to the specified position where it fits the inner wall of the sedimentation tank 1, and then hits the inner wall of the sedimentation tank 1.

[0032] Then, the top of the slide bar 123 away from the second scraper 121 is provided with a third slide groove 127, and the third slide groove 127 is adapted to the length of the push rod 175. The top of the third slide groove 127 is fixedly provided with a protrusion 128, and the protrusion 128 is of a smooth structure. In this way, the protrusion 128 and the end of the push rod 175 are both of smooth structure, ensuring that when the push rod 175 squeezes the protrusion 128, the slide bar 123 can slide obliquely upward along the second slide groove 18; therefore, the slide bar 123 and the corresponding second slide groove 18 are both inclinedly arranged to drive the narrower end of the second scraper 121 to hit the inner wall of the sedimentation tank 1 in an oblique 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, and the several notches 122 opened at the end can better shovel off the loose attachment layer, which is convenient for the next step. Scraping. It should also be noted that the reason why several groups of first scraper assemblies 12 are set up, and the second scrapers 121 are arranged side by side and fit against the inner wall of the sedimentation tank 1, is that, firstly, such multiple groups arranged side by side can more efficiently realize the reciprocating vibration zone to remove loose attachments, because if it is a single plate, in actual application, it is not easy to achieve reciprocating vibration due to its length problem, and multiple groups can more easily achieve this movement effect; secondly, it is to avoid the second scraper 121 being stuck or unable to reset due to the stubborn or raised attachment layer in a certain place. For multiple groups of second scrapers 121, if one of them cannot be reset or stuck, it will not affect the other second scrapers 121 to impact and operate on other parallel places. If it is a whole piece, a raised place may affect the impact operation of other areas.

[0033] The push rod 175 is parallel to the axial direction of the slide bar 123, which can ensure that the push rod 175 obliquely lifts the slide bar 123; at the same time, there is a movable space between the end of the slide bar 123 away from the second scraper 121 and the top of the second slide groove 18, which can ensure that the slide bar 123 has space to slide obliquely upward; in addition, the area of ​​the gear 171 containing teeth is adapted to the distance that the moving rod 174 needs to move to complete the lifting of the protrusion 128 and fall, which can ensure that when the gear 171 and the upper and lower ends of the opening 173 of the moving plate 172 are respectively engaged, the push rod 175 can be driven to lift the protrusion 128 and make it fall, completing the process of the second scraper 121 hitting the inner wall of the sedimentation tank 1 once. With this movement, the second scraper 121 can realize the reciprocating movement of hitting the inner wall of the sedimentation tank 1.

[0034] Further, such as Figure 2 and Figure 3As shown, a lifting assembly 7 is arranged on the threaded screw 5 located on the same side of the drain pipe 2, and a first scraper 8 is arranged at the bottom end of the lifting assembly 7, which is in contact with the inner wall of the bottom end of the sedimentation tank 1, so as to scrape off the sediment on the bottom wall; the lifting assembly 7 includes an outer cylinder 71 with a bottom end fixedly connected to the first scraper 8. In the initial state, the first scraper 8 is arranged adjacent to the driving assembly 4, and an inner cylinder 72 is slidably connected inside 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 to the outside of the outer cylinder 71, and a telescopic rod 74 is slidably connected inside 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 outer wall of the inner cylinder 72 is provided with an extrusion block 76 which is fixedly connected to the outer wall of the inner cylinder 72 and is threadedly connected to the threaded screw 5. By arranging the outer cylinder 71 to be slidably connected to the inner cylinder 72 and the inner cylinder 72 to be slidably connected to the telescopic rod 74, the threaded screw 5 can be supported. Secondly, the elastic force of the first spring 73 and the second spring 75 in the outer cylinder 71 and the inner cylinder 72 can be used to squeeze the first scraper 8 so that it fits the bottom wall of the sedimentation tank 1. In addition, 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 to prevent the first scraper 8 from getting stuck. Finally, the overall telescopic space can be reduced, so that the threaded screw 5 can fit the bottom wall of the sedimentation tank 1 more closely in the initial state. In this way, the mounting plate 9 can be closer to the bottom wall of the sedimentation tank 1, so that it can clean more inner wall attachments.

[0035] Furthermore, the second scraper assembly 13 includes an arc-shaped plate 131, a material trough 20 is opened on one side of the mounting plate 9, a mounting rod 21 is fixedly connected in the material trough 20, and 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 on the top of the arc-shaped plate 131. The third scraper 132 fits the inner wall of the sedimentation tank 1. The third scraper 132 is made of a soft material, such as rubber. A convex rod 133 is fixedly provided on the top of the arc-shaped plate 131 adjacent to the third scraper 132 just below the convex rod 133. The top of the rod 133 is a smooth structure, and the material of the third scraper 132 should be soft so that it can be squeezed and deformed when encountering a protrusion or a stubborn sediment attachment layer, and then contact the convex rod 133 with a smooth structure, thereby lifting the arc plate 131 and temporarily skipping over a certain protrusion, etc., and it should have a certain hardness so that it can play a scraping role when scraping off the ordinary attachment layer and the attachment layer after the second scraper 121 hits it. Therefore, rubber can be realized, and other related materials can also be used. Here, only rubber is taken as an example.

[0036] A torsion spring 134 is fixedly arranged at the connection between the arc plate 131 and the mounting rod 21, one end of the torsion spring 134 is fixedly connected to the arc plate 131, and the other end is fixedly connected to the mounting rod 21, and the torsion spring 134 always has a tendency to rotate the arc plate 131 in the direction of fitting with the inner wall of the sedimentation tank 1, so that the third scraper 132 can always fit the inner wall of the sedimentation tank 1 to scrape off the sediment attachment layer loosened by the impact of the second scraper 121, and secondly, when encountering a stubborn layer or protrusion locally, under the action of the convex rod 133 with a smooth structure, the arc plate 131 can be rotated in the direction away from the inner wall of the sedimentation tank 1, thereby not affecting The other arc plates 131 drive the third scraper 132 to work, and after passing over the protrusion or stubborn layer, the arc plate 131 will be reset to the position in contact with the inner wall of the sedimentation tank 1 under the action of the torsion spring 134, and then the stubborn layer or protrusion can be gradually scraped off through multiple up and down movements. It should be noted that the reason why several groups of arc plates 131 corresponding to the second scraper 121 are arranged and also arranged side by side is that when working together with the second scraper 121, when encountering the stubborn layer or protrusion at the same place, they can achieve synchronous jumping and passing without affecting the operation of other second scrapers 121 and the third scraper 132.

[0037] Both sides of the first scraper 8, the second scraper 121, the third scraper 132 and the protruding rod 133 leave gaps with the inner walls on both sides of the sedimentation tank 1, but are close to the inner wall of the sedimentation tank 1, so as to minimize the impact on other inner walls around the sedimentation tank 1 when working at the same time, and most of the inner walls of the sedimentation tank 1 can be scraped as much as possible.

[0038] In addition, see Figure 1-Figure 3 As shown, an airbag 6 is arranged on the threaded screw 5 between the extrusion block 76 and the mounting plate 9, the airbag 6 is sleeved on the threaded screw 5, and the airbag 6 is filled with a sediment treatment agent, and a dosing pipe 10 is arranged on the mounting plate 9 above the first scraper assembly 12, the dosing pipe 10 is connected to a plurality of high-pressure nozzles 11, the dosing pipe 10 is connected to the airbag 6, and the sediment treatment agent in the airbag 6 is sprayed toward the sediment attachment layer on the inner wall of the sedimentation tank 1 through the plurality of high-pressure nozzles 11.

[0039] In addition, Figure 4-Figure 6 As shown, limiting components 14 are fixedly installed on both sides of the mounting plate 9, and the limiting components 14 include limiting plates 141 fixedly connected to both sides of the mounting plate 9. The top of the limiting plate 141 is rotatably connected to a roller 142, and the roller 142 fits against the inner wall of the sedimentation tank 1. In this way, the mounting plate 9 can reduce the resistance to movement during the up and down movement, and at the same time, it can limit the mounting plate 9 so that it will not rotate and can only move up and down along the inner wall of the sedimentation tank 1.

[0040] Working principle: 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 extrusion airbag 6 is squeezed, the treatment agent therein is sprayed toward the attachment layer through the high-pressure nozzle 11, so that it is separated from the inner wall of the sedimentation tank 1 and falls off or loosens, which is convenient for the operation of the second scraper 121 and the third scraper 132 mentioned above. 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 sediment attachments that fall on the bottom are scraped into the vicinity of the drain pipe 2 by the first scraper 8 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 easily affects the physical and mental health of the staff.
