Description

Technical Field

[0001] The present invention relates to the technical field of internal mixer feeding, and specifically to an internal mixer feeding device. Background Art

[0002] Internal mixers are increasingly widely used in the chemical industry, and their main function is to knead materials. The feeding device is an important part of the internal mixer, and the overall requirements for it are fast feeding, high precision, and no pollution.

[0003] Traditional internal mixer feeding devices are mainly used in the rubber mixing industry, and their feeding methods mainly use rubber conveyor belts (rubber is in a sheet solid state). The traditional structure mainly has the disadvantages of slow feeding speed of the rubber sheet, inaccurate weighing, inability to open and clean the rear side of the feeding cylinder, and inability of the dust exhaust hood structure to quickly exhaust dust, resulting in environmental pollution.

[0004] Secondly, traditional internal mixer feeding devices transport kneaded powder materials. High-value chemical auxiliary powder materials need to be packaged in low-melting-point plastic bags and then placed on the conveyor belt and fed into the feeding cylinder. This will seriously affect the final quality of the kneaded materials due to the addition of plastic bags. In addition, if it is transported to the feeding cylinder through a pipeline, it will cause pipeline residue and slow feeding speed of the added powder materials, with a time difference. Due to the time difference, the final quality of the kneaded materials is uneven, and there are large differences in the kneading quality of different batches. Traditional internal mixer feeding devices also have the disadvantages of inability to open and clean the rear cover of the feeding cylinder and poor dust removal effect of the dust exhaust hood.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Embodiment 1

[0024] As Figures 1-4As shown in the figure, this embodiment includes a feeding cylinder 10 and a dust exhaust cylinder 20 provided on one side of the feeding cylinder 10. In this embodiment, the feeding cylinder 10 and the dust exhaust cylinder 20 are arranged in parallel; and the feeding cylinder 10 is fixedly connected to the dust exhaust cylinder 20. The feeding cylinder 10 and the dust exhaust cylinder 20 share one side wall, that is, the feeding cylinder 10 and the dust exhaust cylinder 20 are integrally formed.

[0025] A feeding door 11 is provided at the lower part of the side of the feeding cylinder 10 facing the dust exhaust cylinder 20. In this embodiment, the bottom of the feeding door 11 is hinged to the feeding cylinder 10; so that the feeding door 11 can be opened and closed on the feeding cylinder 10.

[0026] An inclined feeding oil cylinder 12 is provided in the dust exhaust cylinder 20, and the output shaft of the feeding oil cylinder 12 is hinged to the feeding door 11. In this embodiment, the output shaft of the feeding oil cylinder 12 is hinged to the upper part of the feeding door 11, so as to control the opening and closing of the feeding door 11 on the feeding cylinder 10 through the telescopic movement of the feeding oil cylinder 12.

[0027] A dust exhaust hood 21 is provided on the dust exhaust cylinder 20, and a wind guiding plate 22 is provided in the dust exhaust hood 21. The bottom of the wind guiding plate 22 is fixedly connected to the side wall of the feeding cylinder 10. In this embodiment, the bottom of the wind guiding plate 22 is fixedly connected to the side wall of the feeding cylinder 10 above the feeding door 11.

[0028] A dust exhaust port 23 is provided on the dust exhaust hood 21, and a dust exhaust flange 24 is provided on the dust exhaust port 23. Thus, the dust exhaust flange 24 is connected to a dust removal system for dust removal. It should be noted that the dust removal device is a dust removal system that can be purchased on the market.

[0029] Thus, when the internal mixer is working, the residual flying powder is discharged into the dust removal system through the inner side of the wind guiding plate 22. When the tipping car pours the chemical additive powder, the wind guiding plate 22 blocks the powder from entering the feeding cylinder 10 through the opening on the front wall, thereby reducing the flying of the chemical additive powder. In addition, all the plates of the dust exhaust hood 21 are made of stainless steel materials, improving the corrosion resistance to the chemical additive powder.

[0030] A tipping car 30 is provided on one side of the dust exhaust cylinder 20. In this embodiment, the tipping car 30 includes a trolley and a box body 5 provided on the trolley. In this embodiment, during the working process of the internal mixer, all the mixing materials (mainly various granular powders) are accurately weighed and loaded into the box body 5.

[0031] A tipping assembly 40 capable of tipping the tipping car 30 is provided in the dust exhaust cylinder 20; that is, a tipping assembly 40 capable of tipping the box body 5.

[0032] The flipping assembly 40 includes an oil cylinder 41 disposed within the dust exhaust cylinder 20, a box shaft 42 rotatably disposed within the dust exhaust cylinder 20, and an axle rod 43 connected to the box shaft 42. The output of the oil cylinder 41 is hinged to the axle rod 43, such that the axle rod 43 can be flipped on the box shaft 42 by the telescopic movement of the oil cylinder 41.

[0033] In this embodiment, the box body 5 and the axle rod 43 have a hook-type structure; as Figure 2 shown, two hook slots 44 are provided on the axle rod 43, and a fixing rod is provided on the flipping vehicle 30. A hanging block matching the hook slot 44 is provided at the lower end of the fixing rod; thus, through the matching of the hook slot 44 and the hanging block, the axle rod 43 drives the same to flip.

[0034] Accordingly, during the operation of the internal mixer, all the mixing materials (mainly various granular powders) are accurately weighed and loaded into the box body 5. When the flipping vehicle 30 is in front of the feeding cylinder 10, the feeding door 11 is opened, and the feeding oil cylinder 12 acts to flip the box body 5, and the powder additive is poured into the feeding cylinder 10 of the internal mixer. When the flipping vehicle 30 reaches the maximum flipping angle position, the oil cylinder 41 needs to act with a small stroke three times to ensure that the powder additive completely falls into the feeding cylinder 10. Among them, the box body 5 and the axle rod 43 adopt a hook-type structure and can be separated when loading materials. Therefore, three box bodies 5 of the flipping vehicle are required in a set of flipping vehicle 30 structures. This configuration can achieve continuous mixing of the internal mixer. The material of the box body 5 needs to be stainless steel to improve the corrosion resistance of the box body to the chemical additive powder. The connecting hooks of the box body 5 and the axle rod 43 are made of copper material and can be replaced after wear.

[0035] In this embodiment, the feeding cylinder 10 includes a rear cover plate 51. One end of the rear cover plate 51 is hinged to the feeding cylinder 10 through a hinge shaft and a hinge, and the other end is hinged to the feeding cylinder 10. Moreover, a cover plate handle 52 is further provided on the rear cover plate 51; thus, during the mixing process of the chemical additive powder, the rear cover plate 51 ensures that the powder does not leak during the mixing process. When the mixing is completed, the rear cover plate can be opened by pulling the cover plate handle 52 to clean the residual powder inside the feeding cylinder and ensure the cleanliness of the inner wall of the feeding cylinder 10. The rear cover plate 51 is fixed to the side wall plate through a hinge-type structure, and the hinge shaft can be lubricated by injecting grease. All components on the inner wall of the feeding cylinder 10 are chrome-plated to improve the corrosion resistance. Oblique holes are opened inside the front wall plate to facilitate the dust exhaust of the residual powder and reduce environmental pollution.

[0036] Thus, the internal mixer feeding device of the present invention completely overcomes the disadvantages of the traditional internal mixer feeding device in the chemical industry. The present invention adopts the setting of the tipping car 30 and the tipping assembly 40, which ensures the rapid addition of the mixing materials and improves the production efficiency. The rear cover plate 51 of the feeding cylinder 10 can be opened to clean the powder inside the feeding cylinder, ultimately improving the quality uniformity and unity of the mixing materials. The dust exhaust hood 21 and the air guide plate 22 overcome the advantages of incomplete dust exhaust and ensure that the powder completely enters the feeding cylinder when the tipping car 30 is feeding.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
