AI Technical Summary
[0003]目前市面上常见的均化装置在对弹性体进行搅拌处理时，多通过均化装置顶部开设的入料口直接将弹性体输入到搅拌装置的内部，而后利用搅拌叶的旋转来对弹性体进行搅拌处理，然而这样直接将弹性体输入到搅拌装置内部的方式会导致后续颗粒直接落入搅拌筒时，易在投料口正下方形成局部高密度堆积，而由于搅拌叶的搅拌范围存在固定“死角”，所以堆积的颗粒难以被快速打散，导致混合时间大幅延长
本实用新型，通过设置的分流座、螺旋导流座、扰流柱和导流板等结构，即可方便后续对输入到搅拌筒内部的弹性体进行有效的分流处理，以此来防止弹性体被直接输入到搅拌筒的内侧，导致弹性体在投料口正下方形成局部高密度堆积，影响后续对弹性体的均化效率，整体实用性更高，能够充分的实现对弹性体的分散处理。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of elastomer production technology, specifically to an elastomer production homogenization device with temperature control function. Background Technology
[0002] Elastomers are a class of polymer materials that can quickly return to their original shape after the removal of external force. They combine the processability of plastics with the high elasticity of rubber and are widely used in automobiles, medical, electronics and other fields. When processing elastomers, production homogenization equipment is used.
[0003] Currently, most homogenization devices on the market directly input the elastomer into the mixing device through the feed port at the top of the homogenization device, and then use the rotation of the mixing blades to mix the elastomer. However, this method of directly inputting the elastomer into the mixing device will cause the particles to fall directly into the mixing drum and easily form a local high-density accumulation directly below the feed port. Since there are fixed "dead zones" in the mixing range of the mixing blades, the accumulated particles are difficult to be quickly dispersed, resulting in a significant extension of the mixing time.
[0004] Therefore, we propose an elastomer production homogenization device with temperature control function to solve the above problems. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a homogenization device for elastomer production with temperature control function. This solves the problem mentioned in the background section where common homogenization devices on the market directly input the elastomer into the mixing device through an inlet at the top, then use the rotation of the mixing blades to agitate the elastomer. However, this direct input method leads to a high-density accumulation of particles directly below the inlet when they fall into the mixing drum. Because the mixing range of the blades has fixed "dead zones," the accumulated particles are difficult to disperse quickly, resulting in a significant extension of the mixing time.
[0006] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: An elastomer production homogenization device with temperature control function includes a stirring drum, a pretreatment drum detachably connected to the top of the stirring drum, and a drive motor fixed in the middle of the top of the pretreatment drum. A feed pipe is installed on one side of the top of the pretreatment cylinder. The output end of the drive motor is connected to a rotating shaft. A flow divider is fitted on the outer ring of the top of the rotating shaft. A flow divider groove is opened on the upper surface of the flow divider. A spiral guide seat is connected to the bottom of the rotating shaft. A turbulence column is fixed on the inner wall of the pretreatment cylinder. A guide plate is distributed below the turbulence column. A guide groove is opened on the upper surface of the guide plate. A through groove is opened on the bottom periphery of the pretreatment cylinder.
[0007] Furthermore, a linkage shaft is fixedly connected to the bottom of the rotating shaft, and a stirring blade is installed on the outer ring surface of the linkage shaft. A scraper is installed on the bottom outer surface of the linkage shaft, and a discharge pipe is installed in the middle of the bottom end of the stirring cylinder.
[0008] Furthermore, a support is connected to the periphery of the mixing drum, and a protective railing is installed at the top of the support, with a ladder fixedly installed on one side of the support.
[0009] Furthermore, one end of the conveying pipe extends through the top of the pretreatment cylinder and into the inner side of the pretreatment cylinder, and the conveying pipe is symmetrically distributed along the vertical center line of the pretreatment cylinder.
[0010] Furthermore, the diversion channels are equidistantly distributed along the center point of the diversion seat, and the diversion channels and the diversion seat form an integrated structure.
[0011] Furthermore, the turbulence columns are equidistantly distributed along the center point of the pretreatment cylinder, and the turbulence columns are staggered.
[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides an elastomer production homogenization device with temperature control function, which has the following beneficial effects: This invention, through the design of a diversion seat, a spiral guide seat, a turbulence column, and a guide plate, facilitates the effective diversion of the elastomer input into the mixing drum. This prevents the elastomer from being directly input into the inner side of the mixing drum, which would cause a localized high-density accumulation of the elastomer directly below the feeding port, affecting the subsequent homogenization efficiency of the elastomer. Overall, this invention is more practical and can fully achieve the dispersion of the elastomer. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention proposes an elastomer production homogenization device with temperature control function, including a stirring drum 1, a temperature control structure provided in the inner wall of the stirring drum 1 to facilitate subsequent temperature adjustment according to actual stirring requirements, and the temperature control structure can be adjusted by a controller, a pretreatment drum 2 detachably connected to the top of the stirring drum 1, and a drive motor 3 fixed in the middle of the top of the pretreatment drum 2. The drive motor 3 is electrically connected to an external controller through wires, and the drive motor 3 is controlled to work by the electrical signal issued by the controller. A feed pipe 4 is installed on one side of the top of the pretreatment cylinder 2. The end of the feed pipe 4 away from the pretreatment cylinder 2 is connected to a pump. The output end of the drive motor 3 is connected to a rotating shaft 5. A flow divider 6 is fitted on the outer ring of the top of the rotating shaft 5. The top of the flow divider 6 is provided with an inclined surface. A flow divider groove 7 is opened on the upper surface of the flow divider 6. A spiral guide seat 8 is connected to the bottom of the rotating shaft 5. A spiral groove is opened in the inner cavity of the spiral guide seat 8. The bottom of the spiral groove penetrates the bottom of the pretreatment cylinder 2 and connects to the inner cavity of the stirring cylinder 1. The spiral groove is arrayed along the center point of the spiral guide seat 8. The pretreatment cylinder 2 has a turbulence column 9 fixedly installed on its inner side wall, and a guide plate 10 is distributed below the turbulence column 9. The top of the guide plate 10 is provided with an inwardly recessed inclined surface, and the guide grooves 11 are equidistantly distributed along the center point of the guide plate 10. The bottom of the guide grooves 11 is provided with multiple through holes at equal intervals. The upper surface of the guide plate 10 is provided with the guide grooves 11. The bottom periphery of the pretreatment cylinder 2 is provided with through grooves 12, which are equidistantly distributed along the bottom center point of the pretreatment cylinder 2. The opening of the through grooves 12 connects the pretreatment cylinder 2 with the stirring cylinder 1. During use, under the action of an external pump, the elastomer to be homogenized is drawn into the inner side of the conveying pipe 4. Under the conveying action of the conveying pipe 4, the elastomer is fed into the inner side of the pretreatment cylinder 2. At this time, the drive motor 3 operates, causing the output shaft 5 to rotate. Since the diverter seat 6 is fixedly connected to the shaft 5, the rotation of the shaft 5 facilitates the subsequent rotation of the diverter seat 6. The rotation of the diverter seat 6 then diverts the elastomer fed to its upper surface. After diversion, the elastomer moves along the diverter groove 7 and the inclined surface of the diverter seat 6, undergoing further diversion. Under the rotation of the diverter seat 6, the diverted elastomer moves along the inner wall of the pretreatment cylinder 2 and passes through multiple turbulence columns 9. Since multiple turbulence columns 9 are arranged in a staggered array, the diverter further diverts the elastomer. Multiple turbulence columns 9 facilitate further dispersion of the elastomer input into the pretreatment cylinder 2. After dispersion, the elastomer falls along the inner wall of the pretreatment cylinder 2 onto the upper surface of the guide plate 10. Some of the elastomer moves along the guide groove 11 on the upper surface of the guide plate 10 and seeps out through the through hole at the bottom of the guide groove 11. Then, it is input into the inner side of the mixing cylinder 1 through the through groove 12. Another part of the elastomer moves along the concave surface of the guide plate 10 and falls onto the upper surface of the spiral guide seat 8. Then, the elastomer is diverted along the spiral groove on the inner side of the spiral guide seat 8 and transported to the inner side of the mixing cylinder 1 through the spiral groove. This achieves effective diversion of the elastomer, which facilitates better homogenization and mixing of the elastomer in the subsequent process, resulting in higher overall practicality.
[0017] like Figure 3 and Figure 4 As shown, in some embodiments, a linkage shaft 13 is fixedly connected to the bottom of the rotating shaft 5, and a stirring blade 14 is installed on the outer ring surface of the linkage shaft 13. A scraper 15 is installed on the bottom outer surface of the linkage shaft 13. The scraper 15 is equidistantly distributed along the center point of the linkage shaft 13, and the outer surface of the scraper 15 is an arc-shaped surface. The outer arc surface of the scraper 15 is in contact with the inner wall of the mixing drum 1. A discharge pipe 16 is installed in the middle of the bottom end of the mixing drum 1. The discharge pipe 16 passes through the bottom of the mixing drum 1 and connects to the inner side of the mixing drum 1. In use, since the linkage shaft 13 is fixedly connected to the bottom of the rotating shaft 5, the linkage shaft 13 fixedly connected to its bottom will rotate along with the rotating shaft 5. The rotation of the linkage shaft 13 will drive the stirring blades 14 fixed on its outer surface to rotate as well. The rotation of multiple stirring blades 14 can facilitate the subsequent homogenization and stirring of the elastomer. As the linkage shaft 13 rotates, the scraper 15 connected to its bottom outer ring surface will move along the inner wall of the mixing drum 1, which facilitates the subsequent cleaning of the inner wall of the mixing drum 1 and prevents too much elastomer from adhering to the inner wall of the mixing drum 1, which would affect the temperature transmission of the temperature control structure in the inner wall of the mixing drum 1. After the elastomer is homogenized, the discharge pipe 16 can be used to achieve the purpose of discharge.
[0018] like Figure 1 As shown, in some embodiments, a support 17 is connected to the periphery of the stirring drum 1, and a guardrail 18 is installed at the top of the support 17, and a ladder 19 is fixedly installed on one side of the support 17. When in use, the ladder 19 can be used to facilitate the climb of operators, while the guardrail 18 is used for protection.
[0019] like Figure 3 and Figure 5 As shown, in some embodiments, one end of the conveying pipe 4 extends through the top of the pretreatment cylinder 2 and into the inner side of the pretreatment cylinder 2, and the conveying pipe 4 is symmetrically distributed along the vertical center line of the pretreatment cylinder 2. When in use, since the conveying pipe 4 is connected to the external storage structure through the pump, the elastic body will be fed into the inside of the pretreatment cylinder 2 through the conveying pipe 4 when the subsequent pump is working.
[0020] like Figure 3 and Figure 5 As shown, in some embodiments, the diversion grooves 7 are equidistantly distributed along the center point of the diversion seat 6, and the diversion grooves 7 and the diversion seat 6 form an integrated structure. In use, when the elastomer is conveyed to the upper surface of the diversion seat 6, the multiple diversion grooves 7 can be used to facilitate the initial diversion process of the elastomer.
[0021] like Figure 3 and Figure 5 As shown, in some embodiments, the turbulence columns 9 are equidistantly distributed along the center point of the pretreatment cylinder 2, and the turbulence columns 9 are staggered. In use, since the baffle columns 9 are equidistantly distributed along the inner side of the pretreatment cylinder 2 and are staggered, when the elastomer is input into the inner side of the pretreatment cylinder 2, the multiple baffle columns 9 can be used to facilitate the subsequent effective diversion treatment of the elastomer.
[0022] In summary, under the action of the external pump, the elastomer to be homogenized is fed into the inner side of the pretreatment cylinder 2 through the feed pipe 4. At this time, the drive motor 3 works to rotate the shaft 5. The rotation of the shaft 5 drives the diverter seat 6 to rotate, thereby diverting the elastomer. After diversion, the elastomer is further diverted by the diverter trough 7 and the inclined surface of the diverter seat 6. The diverted elastomer passes through multiple turbulence columns 9 for further dispersion. After dispersion, the elastomer falls along the inner wall of the pretreatment cylinder 2 onto the upper surface of the guide plate 10. Some of the elastomer moves along the guide groove 11 on the upper surface of the guide plate 10 and seeps out through the through hole at the bottom of the guide groove 11. Then, the elastomer is fed into the inner side of the mixing drum 1 through the through groove 12. Another part of the elastomer moves along the concave surface of the guide plate 10 and falls onto the upper surface of the spiral guide seat 8. The elastomer is then diverted along the spiral groove opened on the inner side of the spiral guide seat 8 and transported to the inner side of the mixing drum 1 through the spiral groove. Then, as the rotating shaft 5 rotates, the linkage shaft 13 drives the stirring blades 14 to rotate. The rotation of multiple stirring blades 14 can facilitate the subsequent homogenization and stirring of the elastomer. As the linkage shaft 13 rotates, the scraper 15 moves along the inner wall of the mixing drum 1, which facilitates the subsequent cleaning of the inner wall of the mixing drum 1. After the elastomer is homogenized, the discharge pipe 16 can be used to achieve the purpose of discharge.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
