Description

TECHNICAL FIELD

[0001] The utility model belongs to rubber processing technical field, especially relate to a rubber processing powder air draft dust collector. BACKGROUND

[0002] Rubber material is a kind of high polymer material including such as artificial synthesis or natural collection. The rubber product obtained by rubber processing includes such as vehicle tire and has very wide application in industry. In actual production process, to modify the performance of rubber, currently, the powder additive including such as active agent magnesium oxide is added to rubber in rubber processing process, to modify rubber product.

[0003] In order to avoid that magnesium oxide is not enough uniform in granularity and is easy to produce "white spot" on rubber, magnesium oxide powder needs to be treated, including such as screening, mixing and processing into pre-dispersion masterbatch. In production process, bagged magnesium oxide powder is added to processing equipment, such as screening equipment, and the operator pours bag material into the equipment, and opens the air draught fan at the position above the equipment.

[0004] But in actual working process, due to the different angles and heights of pouring material, the positions of dust concentration and diffusion are different in the pouring process, such as the operator tilts bag material at the edge position of the screen of screening machine to save labor, which causes dust to diffuse outward, and magnesium oxide is high in fineness, so a large amount of dust diffuses outward in the pouring process, although the fan can air draft, but the fan in the inverted state cannot aim the air hood to the dust concentration and diffusion area, and once dust diffuses widely, the air hood cannot fully suck dust. It causes dust to diffuse to workshop.

[0005] Therefore, in actual working process, the amount of dust generated and the position of concentration in the pouring process of bagged bag material are often related to the position of the operator's pouring operation, especially the pouring of wide-mouthed shaking screen, if the air hood cannot be aimed at the pouring position, a large amount of dust is difficult to be quickly concentrated and sucked and removed after pouring, which causes part of dust to diffuse to workshop.

[0042] Embodiment 1

[0043] As Figures 1-5 ​​As shown, a rubber processing powder suction device, comprising an upper suction hood 1, the bottom of the upper suction hood 1 is provided with a lower suction hood 4. In order to adjust the height of the lower suction hood 4 according to the amount of dust, when the height of the pouring is too high during the pouring process, the amount of dust escaping is very large, at this time, by adjusting the height of the lower suction hood 4 to the dust pouring position, the escaping (not yet diffused) dust is quickly concentrated and sucked.

[0044] Specifically, the upper suction hood 1 and the lower suction hood 4 are installed through the spring telescopic structure, and the height of the lower suction hood 4 can be adjusted through the spring telescopic structure. Specifically, the spring telescopic structure comprises a lower spring air pipe 3 fixedly installed between the upper suction hood 1 and the lower suction hood 4; the spring telescopic structure further comprises a plurality of cylinder structures for lifting the lower suction hood 4.

[0045] Specifically, the bottom of the upper suction hood 1 and the lower spring air pipe 3 are assembled and connected through the flange connection structure; specifically, the flange connection structure comprises an upper flange plate 11 fixedly connected to the bottom of the upper suction hood 1, and the top of the lower spring air pipe 3 is fixedly connected with a lower flange plate 31, and the upper flange plate 11 and the lower flange plate 31 are assembled and connected through a plurality of bolts.

[0046] Among them, the lower spring air pipe 3 is a conventional spring pipe disclosed in the prior art, which can be stretched and lengthened within a certain height range due to the spring structure.

[0047] At the same time, the cylinder structure comprises a push cylinder 5 arranged at the front and rear positions of the lower spring air pipe 3 respectively, and the piston rod of the push cylinder 5 is installed at the top of the lower suction hood 4.

[0048] Specifically, the installation method of the cylinder is that the cylinder barrel of the push cylinder 5 is fixedly installed on the outer side wall of the lower flange plate 31, specifically, the outer side wall of the lower flange plate 31 is welded and fixedly connected with an upper cylinder barrel seat 51, and the cylinder barrel of the push cylinder 5 is fixedly installed at the bottom of the upper cylinder barrel seat 51.

[0049] The top of the lower suction hood 4 is integrally formed with an annular boss 41, the outer side wall of the annular boss 41 is fixedly connected with a lower piston rod seat 52, and the piston rod of the push cylinder 5 is fixedly connected to the top of the piston rod seat 52.

[0050] During operation, when it is necessary to lower the lower suction hood 4 to increase the suction of the concentrated escaping dust by the lower suction hood 4, the operator opens the push cylinder 5, and under the pushing of the push cylinder 5, at this time, the push cylinder 5 pushes the lower suction hood 4 downward, and in the process of pushing downward, the lower spring air pipe 3 is stretched, and the lower suction hood 4 moves downward to approach the dust pouring area, at this time, a large amount of escaping dust is sucked by the lower suction hood 4 before it is diffused in a large range. By this way, the large amount of dust escaping is prevented, and the height of the suction hood is adjusted according to the escaping condition of the dust during the pouring process.

[0051] Example 2

[0052] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, an upper spring duct 2 (with a diameter larger than that of the lower spring duct 3) is installed on the top of the upper exhaust hood 1. The upper spring duct 2 is connected to an external exhaust structure (not shown in the figure). Specifically, the principle and structure of dust extraction and removal are the same as those of existing exhaust hoods. The external exhaust structure includes an exhaust pipe (the exhaust pipe is installed on the top of the upper spring duct 2 via a flange 21). A dust extraction fan is installed at the outlet of the exhaust pipe, such as an axial flow fan installed inside the exhaust pipe, as is common in existing systems.

[0053] The above method achieves the same principle as existing dust extraction and removal, using a fan inside the extraction duct to drive the dust extraction process.

[0054] Example 3

[0055] like Figures 1-5 As shown, this embodiment is based on the structure of embodiment 2. In the process of exhaust dust removal, in order to align the exhaust hood with the material pouring area, such as when the material is poured onto the edge of the screen of the screening machine (normally, the exhaust hood is aligned with the center of the screen of the screening machine, but it is often inconvenient to pour the bag material into the center of the screen, so in actual operation, the bag material is often poured onto the edge of the screen).

[0056] Therefore, a pushing structure is hinged to the upper exhaust hood 1. This pushing structure drives the upper exhaust hood 1 and the lower exhaust hood 4 to rotate and adjust the exhaust angle. When the lower exhaust hood 4 rotates and adjusts its angle, the opening of the lower exhaust hood 4 faces the material dumping area, thereby achieving rapid and concentrated extraction and removal of dust that has not yet fully diffused into the workshop.

[0057] The pushing structure includes pushing cylinders 6 (which are conventional hydraulic cylinders disclosed in the prior art) that are hinged to the front and rear side walls of the upper exhaust hood 1 respectively; the pushing directions of the pushing cylinders 6 are opposite (i.e., the rear pushing cylinder 6 is located at the left end of the rear side of the upper exhaust hood 1, and the front cylinder is located at the right end of the front side of the upper exhaust hood 1); the cylinder barrels of the pushing cylinders 6 are respectively hinged to brackets 7. The brackets support the entire hood structure above the working equipment, such as a screening machine.

[0058] Specifically, pins are fixedly connected to the center of the front and rear side walls of the upper exhaust hood 1, and a hinge seat 61 hinged to the pins is fixedly connected to the plunger rod of the push cylinder 6; an ear seat is fixedly connected to the cylinder barrel of the push cylinder 6, and a hinge bracket 62 is hinged to the ear seat. The hinge bracket 62 is fixedly installed at the top of the bracket 7.

[0059] In the working process, when it is needed to turn the whole exhaust hood structure to the left side, at this time, the front pushing oil cylinder 6 pushes the whole hood structure to the left side, and the rear pushing oil cylinder 6 pulls the whole hood structure to the left side.

[0060] Conversely, in the process, because the top of the whole exhaust hood structure is designed through the upper spring air pipe 2, the upper spring air pipe 2 has a certain elastic freedom, and the whole exhaust hood structure is realized to swing left and right. In the working process, it is convenient to turn the exhaust hood structure to the material dumping position, because the whole exhaust hood structure is turned to the material dumping area, so that the dust can be sucked with stronger wind power in the working process. In this way, further solve the problem that the dust is fully exhausted in a short time during the dumping of the magnesium oxide powder, and the dust is avoided to escape.

[0061] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. The changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
