Description
TECHNICAL FIELD
[0001] The utility model belongs to rubber refining technical field especially relates to a rubber refining air draft dust collector. BACKGROUND
[0002] The rubber refining mainly includes the open mixing and the banburying, unlike the banburying working in the closed environment, the open mixing of the rubber is exposed in the air process. Through the banburying or the open mixing of the rubber, the rubber material is continuously rolled and extended by the rubber mixing roller, and after repeatedly rolling and extending the rubber material, the rubber molecules are pulled up to improve the performance of the rubber.
[0003] In the rubber open mixing process, various auxiliary materials such as vulcanizing agent are often added to the rubber to increase the performance of the rubber. In the process of rolling and extending the rubber material, the temperature of the rubber mixing roller is high, so the auxiliary materials and the rubber are easy to escape into the workshop. Because the auxiliary materials such as vulcanizing agent and resin are mixed with the rubber molecules, not only the dust is formed, but also the dust has a certain viscosity in the high temperature environment, and after cooling, it is easy to adhere to the attachments such as the walls and equipment of the workshop, which is difficult to clean in the later period and has a great impact on the health of the workers.
[0004] Therefore, in the prior art, an air draft cover and an air draft pipe are installed at the upper end of the open mill to draft air. During the air draft process, because the airflow continuously enters the cover and continuously reduces the temperature of the cover body, the dust with a certain viscosity adheres to the inner wall of the cover body, and the temperature of the cover body decreases rapidly, and the dust is quickly solidified on the cover body. After the dust is completely cooled and solidified, a layer of agglomerate layer is attached to the inner wall of the cover body. Not only is it difficult to clean in the later period, but also the thickness of the agglomerate layer increases year after year, which reduces the air volume and the dust removal effect in the later period, and it is very difficult to clean up later.
[0005] The specific factor is that the dust generated by the rubber open mixing has viscosity (mainly high temperature rubber molecules and resin molecules) and is easy to adhere to the cover body, and the existing air draft cover is difficult to remove the adhering objects, which affects the air draft and dust removal effect after a long time.

[0041] Embodiment 1
[0042] As Figures 1-6 As shown, a rubber refining exhaust dust removal device, comprising an exhaust dust removal cover, the exhaust dust removal cover comprises a cover body, the shape of the cover body is that: the cover body comprises a conical part 11 and a cover barrel part 12 integrally formed at the bottom position of the conical part 11, and the transverse interface shape of the cover barrel part 12 is rectangular. At the same time, the top of the cover body is communicated with an exhaust pipe 13, and according to the existing exhaust dust removal mode, the exhaust pipe 13 is communicated to an external exhaust dust removal pipeline (not shown in the figure) (the external exhaust dust removal pipeline is provided with dust removal equipment such as an axial flow fan).
[0043] In order to realize the exhaust dust removal process, when high-temperature rubber is refined, the high-temperature rubber particles and auxiliary material particles are easily attached to the inner side wall of the cover body due to high viscosity during the exhaust dust removal process, and after cooling, they are scaled on the cover body. The cover body is improved as follows:
[0044] A plurality of scale removal mechanisms 4 are installed on the side wall of the cover body; specifically, the width of the front and rear side of the cover barrel part 12 is less than the width of the left and right side of the cover barrel part 12; a scale removal mechanism 4 is installed on the front and rear side wall of the cover barrel part 12 at the center position, and one scale removal mechanism 4 is installed on the left and right side walls of the cover barrel part 12 respectively (the width of the left and right side of the cover barrel part 12 is large, and a pair of scale removal mechanisms 4 are used to achieve sufficient scale removal).
[0045] That is, a scale removal mechanism 4 is installed on each side wall of the cover barrel part 12 to achieve sufficient cleaning of the cover barrel part 12.
[0046] Specifically, the scale removal mechanism 4 comprises a pair of scale removal plates 43 abutting against the inner side wall of the cover body (spaced apart on both sides), and a plurality of slide arms 42 are respectively installed on the scale removal plates 43 and slidably connected to the cover body.
[0047] Specifically, two slide arms 42 are installed on the outer side wall of the scale removal plate 43, and the side wall of the cover body is provided with a long slide opening 2 matched with the slide arm 42, specifically, the side wall of the cover barrel part 12 is provided with a long slide opening 2 spaced apart upward and downward, and the slide arm 42 penetrates from the position of the long slide opening 2. The slide arm 42 slides in the long slide opening 2.
[0048] The above-mentioned scale removal mechanism 4 further comprises two upward and downward spaced apart air cylinders 41, the air cylinder 41 adopts a double piston rod air cylinder 41, and the piston rods on both sides of the double piston air cylinder 41 are respectively fixedly connected with a connecting seat 411, and the connecting seat 411 is fixedly installed on the slide arm 42 through a mounting rod 412.
[0049] In the working process, under the action of the cylinder 41, at this time, the two sides of the scraping plate 43 reciprocate on the side wall of the cover body. In the moving process, the adhered dirt layer on the inner wall of the cover body after cooling is removed. Specifically, the dirt layer after cooling and drying not only has greatly reduced viscosity, but also has increased hardness, so it is easy to be scraped off by the scraping plate 43. In this process, the sliding arm 42 is limited to slide in the long sliding port 2, so the stability of the scraping movement is high.
[0050] By the above-mentioned mode, the technical defect that the adhered dirt hidden on the inner wall of the cover body is difficult to clean is solved. After cleaning in a simple and convenient way, the maintenance efficiency of the air extraction equipment is greatly improved, and the technical problem that the air volume is reduced in the air extraction and dust extraction process due to the accumulation of the dirt layer which is difficult to clean is effectively solved.
[0051] Embodiment 2
[0052] As shown in Figures 1-6 the structure of embodiment 1, the two sides of the scraping plate 43 are respectively provided with curved scrapers 44. In the scraping wall process of the scraping plate 43, the curved scrapers 44 are elastically contacted on the inner side wall of the cover body and elastically scrape dirt. By the curved scrapers 44 made of elastic material, the curved scrapers 44 are always closely attached to the inner side wall of the cover body, and the scraping of the scraping plate 43 is easy to be incomplete after the increase of abrasion.
[0053] The shape of the curved scraper 44 is that the curved scraper 44 includes a curved portion 441, and the curved portion 441 is integrally formed with a scraper portion 442. The length of the curved scraper 44 is the same as the length of the scraping plate 43.
[0054] In the reciprocating movement process of the curved scraper 44 following the scraping plate 43 on the inner side wall of the cover body, the curved scraper 44 elastically contacted on the inner side wall of the cover body continuously scrapes off dirt. In this process, since the curved scraper 44 is made of elastic material (the curved scraper 44 is a thin silicon steel sheet), it is always in contact with the cover wall.
[0055] The structure design of the curved portion 441 of the curved scraper 44 ensures that the curved scraper 44 can form a deformation buffer space in the process of elastic deformation, reduce stress, and thus maintain long-term elastic performance, so as to ensure that it is closely contacted with the inner side wall of the cover body for a long time.
[0056] Embodiment 3
[0057] As shown in Figures 1-6 the structure of embodiment 2, under normal conditions, the distance between the cover body and the equipment is fixed. When the amount of dust is very large, if the dust is not extracted in time, a large amount of dust will escape from the workshop. At this time, after the extension cover 3 connected to the bottom of the cover body is lowered, the distance between the extension cover 3 and the dust is reduced, and the dust extraction effect is improved.
[0058] Specifically, the bottom of the cover is provided with a rectangular slot (the rectangular slot has a certain depth, and the top of the slot is lower than the height of the long sliding opening 2) matched with the extension cover 3, and the extension cover 3 is limited to slide in the rectangular slot. Moreover, the lower end of the outer side wall of the cover is threadedly connected with a plurality of locking bolts 31 locked on the extension cover 3. The locking bolts 31 penetrate into the rectangular slot and press the extension cover 3. After the locking bolts 31 are loosened, the height is lowered through the extension cover 3, so that the dust removal effect is increased.
[0059] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the present application should also be within the protection scope of the present application.
