Abstract
Description
Technical Field
[0001] This utility model relates to the field of modifier mixing technology, and more specifically, to a corrosion-resistant reclaimed rubber production equipment that uniformly disperses composite modifiers. Background Technology
[0002] Reclaimed rubber, a rubber material made by reprocessing waste rubber products, is widely used in the rubber industry due to its advantages such as resource reuse and reduced production costs. To improve the performance of reclaimed rubber, composite modifiers are usually added to change the molecular structure of rubber through physical or chemical actions, giving reclaimed rubber excellent properties such as corrosion resistance, wear resistance, and aging resistance.
[0003] However, in existing reclaimed rubber production processes, the uniform dispersion of compound modifiers has always been a key factor restricting product quality improvement. Traditional production equipment mostly uses simple stirring or mixing methods to mix the rubber matrix, making it difficult to achieve a uniform distribution of various modifiers with different properties in the rubber matrix. This results in uneven performance of the reclaimed rubber, seriously affecting its performance in practical applications. Furthermore, the relatively fixed inlet for adding modifiers is not conducive to the full dispersion of modifiers. Only by extending the stirring time can uniformity be increased, which reduces the dispersion efficiency of compound modifiers. Utility Model Content
[0004] The main objective of this invention is to provide a corrosion-resistant reclaimed rubber production equipment with uniform dispersion of composite modifiers, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A corrosion-resistant recycled rubber production equipment with uniform dispersion of composite modifiers includes a stirring device, and a crushing device is fixedly installed on the top of the stirring device.
[0007] The crushing device includes a dispersing box, with a feed inlet fixedly connected to the top of the dispersing box and a discharge nozzle fixedly connected to the bottom of the dispersing box. A crushing motor is fixedly installed on the side of the dispersing box, and a crushing shaft is fixedly installed at the output end of the crushing motor. Multiple pushing blocks are fixedly sleeved on the outer surface of the crushing shaft. The crushing shaft and pushing blocks are rotatably installed inside the dispersing box. A crushing chamber is fixedly connected to the left side of the dispersing box, and crushing blocks are fixedly installed on the left side of the crushing chamber. An arc-shaped filter screen is fixedly installed at the bottom of the dispersing box above the discharge nozzle, and multiple material distribution plates are fixedly installed inside the discharge nozzle.
[0008] Preferably, the material distribution plate is inverted V-shaped, and the material distribution plate has two layers, with the two layers of material distribution plates interleaved.
[0009] Preferably, the mixing device includes a mixing chamber, the bottom of which is fixedly connected to a discharge port, and the discharge port is equipped with a switch valve inside. The top of the mixing chamber is fixedly connected to the bottom of the discharge nozzle.
[0010] Preferably, a stirring motor is fixedly installed on the side of the mixing tank, a stirring shaft is fixedly installed at the output end of the stirring motor, a plurality of first stirring blades are fixedly sleeved on the outer surface of the stirring shaft, a second stirring blade is rotatably installed on the outer surface of the stirring shaft, scrapers are fixedly installed on both sides of the second stirring blade, a fixed box is fixedly installed on the inner wall of the mixing tank near the stirring motor, a first bevel gear is rotatably installed at the upper end of the fixed box, a second bevel gear is fixedly sleeved at the end of the stirring shaft near the stirring motor, the outer surface of the second bevel gear meshes with the first bevel gear, and a third bevel gear is fixedly connected to one end of the second stirring blade.
[0011] Preferably, the third bevel gear is movably sleeved on the outer surface of the stirring shaft, and the outer surface of the third bevel gear meshes with the outer surface of the first bevel gear.
[0012] Preferably, the paddles inside the second stirring paddle are staggered with the first stirring paddle, and the scraper is rotatably mounted on the inner wall of the mixing tank.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By setting up crushing blocks and crushing chambers, the pushing block pushes the agglomerated composite modifier to the side of the crushing block, causing the agglomerated composite modifier to be impacted and broken. The agglomerated composite modifier then slides down the inclined surface of the dispersing box to the top of the arc-shaped filter screen for filtration. This process breaks up the agglomerated composite modifier and prevents it from affecting the mixing effect.
[0015] 2. The material distribution plate has two layers, and the two layers are staggered to disperse the incoming composite modifier. The composite modifier is then fed into the mixing box through the discharge nozzle, resulting in more uniform dispersion and reduced mixing time.
[0016] 3. Through the action of the first bevel gear, the first stirring paddle stirs the composite modifier clockwise, while the second stirring paddle stirs the composite modifier counterclockwise, thereby improving the mixing effect of the composite modifier. Furthermore, the scraping of the inner wall of the mixing chamber by the scraper improves the mixing efficiency and prevents the composite modifier from adhering to the inner wall of the mixing chamber, which would affect the mixing effect between the composite modifier and the rubber matrix.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] As attached Figure 1 To be continued Figure 3 As shown, an embodiment of this utility model provides a corrosion-resistant recycled rubber production equipment with uniform dispersion of composite modifier, including a stirring device 1, and a crushing device 2 fixedly installed on the top of the stirring device 1.
[0025] like Figures 2-3 As shown, the crushing device 2 includes a dispersing box 21. The top of the dispersing box 21 is fixedly connected to a feed inlet 22, and the bottom of the dispersing box 21 is fixedly connected to a discharge nozzle 23. A crushing motor 29 is fixedly installed on the side of the dispersing box 21. A crushing shaft 26 is fixedly installed at the output end of the crushing motor 29. Multiple pushing blocks 27 are fixedly sleeved on the outer surface of the crushing shaft 26. The crushing shaft 26 and the pushing blocks 27 are rotatably installed inside the dispersing box 21. A crushing chamber is fixedly connected to the left side of the dispersing box 21, and a crushing block 25 is fixedly installed on the left side of the crushing chamber. An arc-shaped filter screen 24 is fixedly installed above the discharge nozzle 23 at the bottom of the dispersing box 21. Multiple material distribution plates 28 are fixedly installed inside the discharge nozzle 23.
[0026] In this system, by setting up crushing blocks 25 and a crushing chamber, when the agglomerated composite modifier is fed into the dispersing box 21 through the feed inlet 22, the crushing motor 29 controls the drive block 27 to rotate through the crushing shaft 26, crushing the agglomerated composite modifier. This causes the agglomerated composite modifier to be pushed to the side of the crushing blocks 25, impacting the agglomerated composite modifier. The crushed composite modifier then slides through the inclined surface of the dispersing box 21 to the top of the arc-shaped filter screen 24, further crushing the agglomerated composite modifier and improving the mixing effect of the composite modifier.
[0027] like Figure 3 As shown, the material distribution plate 28 is inverted V-shaped and consists of two layers. The two layers of material distribution plate 28 are staggered to disperse the incoming composite modifier. The composite modifier is then fed into the mixing box 11 through the discharge nozzle 23, resulting in more uniform dispersion of the composite modifier and reducing the mixing time of the composite modifier.
[0028] like Figure 4 As shown, the mixing device 1 includes a mixing tank 11, the bottom of which is fixedly connected to a discharge port 12, and a switch valve 13 is provided inside the discharge port 12. The top of the mixing tank 11 is fixedly connected to the bottom of the discharge nozzle 23.
[0029] like Figure 5 As shown, a stirring motor 14 is fixedly installed on the side of the mixing tank 11. A stirring shaft 15 is fixedly installed at the output end of the stirring motor 14. Multiple first stirring paddles 16 are fixedly sleeved on the outer surface of the stirring shaft 15. A second stirring paddle 17 is rotatably installed on the outer surface of the stirring shaft 15. Scrapers 18 are fixedly installed on both sides of the second stirring paddle 17. A fixed box 19 is fixedly installed on the inner wall of the mixing tank 11 near the stirring motor 14. A first bevel gear 110 is rotatably installed on the upper end of the fixed box 19. A second bevel gear 111 is fixedly sleeved on the end of the stirring shaft 15 near the stirring motor 14. The outer surface of the second bevel gear 111 meshes with the first bevel gear 110. A third bevel gear 112 is fixedly connected to one end of the second stirring paddle 17.
[0030] The third bevel gear 112 is movably sleeved on the outer surface of the stirring shaft 15, and the outer surface of the third bevel gear 112 meshes with the outer surface of the first bevel gear 110.
[0031] The paddles inside the second stirring paddle 17 are staggered with those inside the first stirring paddle 16, and the scraper 18 is rotatably mounted on the inner wall of the mixing tank 11.
[0032] Through the action of the first bevel gear 110, when the stirring motor 14 controls the stirring shaft 15 to rotate, the second bevel gear 111, through the rotation of the first bevel gear 110, causes the third bevel gear 112 and the second stirring paddle 17 to rotate in opposite directions inside the mixing chamber 11. This causes the first stirring paddle 16 to stir the composite modifier clockwise, while the second stirring paddle 17 stirs the composite modifier counterclockwise, improving the mixing effect of the composite modifier. Furthermore, the scraper 18 scrapes the inner wall of the mixing chamber 11 to prevent the composite modifier from adhering to the inner wall of the mixing chamber 11, thus affecting the mixing effect of the composite modifier and the rubber matrix.
[0033] The working process of this utility model is as follows:
[0034] In use, the rubber matrix is first placed into the mixing box 11. Then, the composite modifier is put into the dispersing box 21 through the feed inlet 22. The crushing motor 29 controls the drive block 27 to rotate through the crushing shaft 26. The drive block 27 pushes the agglomerated composite modifier to the side of the crushing block 25, causing impact to the agglomerated composite modifier, breaking it up. The agglomerated composite modifier slides through the inclined surface of the dispersing box 21 to the top of the arc-shaped filter screen 24 for filtration. The broken agglomerated composite modifier enters the discharge nozzle 23 through the arc-shaped filter screen 24. The composite modifier entering the discharge nozzle 23 is dispersed by the guidance of two interlaced distribution plates 28 and is then put into the mixing box 11 through the discharge nozzle 23, making the composite modifier more evenly dispersed.
[0035] Subsequently, when the stirring motor 14 controls the stirring shaft 15 to rotate, the second bevel gear 111 rotates, and through the action of the first bevel gear 110, the third bevel gear 112 drives the second stirring paddle 17 to rotate in the opposite direction inside the mixing chamber 11. When the first stirring paddle 16 stirs the composite modifier clockwise, the second stirring paddle 17 stirs the composite modifier counterclockwise, improving the mixing effect of the composite modifier. The scraper 18 scrapes the inner wall of the mixing chamber 11 to prevent the composite modifier from adhering to the inner wall of the mixing chamber 11.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
