[0002] An internal mixer, also known as a kneader, rubber mixing machine, or high-speed mixer, is a piece of equipment specifically designed for the plasticizing and mixing of rubber. Internal mixers are mainly used for kneading, dispersing, mixing, and plasticizing various rubber, plastic raw materials, engineering modifiers, metal powders, ceramic powders, and other raw materials. They are widely used in the production of raw materials for rubber and plastic products such as EVA, PVC, TPR, PE, PP, PC, metal powders, ceramic powders, functional masterbatches, rubber additives, shoe materials, rubber tires, sealing components, electronic products, wires and cables, and automotive products.

[0003] In the existing technology, the surface of the existing internal mixer has some pores. When processing some dusty materials, the dust will overflow to the outside of the internal mixer through the pores, which will degrade the surrounding environment. At the same time, the loss of materials will cause waste and affect the material ratio. Utility Model Content

[0042] like Figure 1-3 As shown, the device for negative pressure dust removal and feeding of the internal mixer includes:

[0043] Negative pressure component 1, wherein a dust suction pipe 7 is fixedly connected to the inner cavity of the internal mixer on the side surface of the negative pressure component 1;

[0044] Feeding shell 2, the feeding shell 2 is fixedly connected to the bottom side of negative pressure component 1, and the end of the feeding shell 2 is fixedly connected to a connecting shell 3, which is connected to the inner cavity of the internal mixer;

[0045] A filtration mechanism 8 is installed inside the negative pressure assembly 1 and is used for filtering dust gas inside the negative pressure assembly 1.

[0046] A feeding assembly is installed on the side surface of the feeding shell 2. The feeding assembly is used to assist the material in the feeding shell 2 in being fed into the internal mixer.

[0047] Under the action of the negative pressure component 1, the dust suction pipe 7 connected to the internal mixer draws in the dust gas, effectively absorbing the dust gas and reducing the overflow of dust through the internal mixer. At the same time, the drawn dust gas enters the negative pressure component 1 and is filtered by the filtration mechanism 8, effectively intercepting the dust in the dust gas. The intercepted dust falls into the inner cavity of the feeding shell 2 for storage. By opening the sealing mechanism 5, the powder in the feeding shell 2 enters the internal mixer for processing. The pushing component assists in pushing the powder, avoiding adhesion in the feeding shell 2 and causing waste. The easily processed powder can be reused, avoiding waste and ensuring the material ratio.

The cover 12 is installed on the top side of the housing 11, and the vacuum pump 13, which communicates with the inner cavity of the housing 11, is installed on the top side of the cover 12. The exhaust pipe 14 is fixedly connected to the output end of the vacuum pump 13.

[0049] The vacuum pump 13 creates a negative pressure vacuum in the sealed housing 11, which facilitates the extraction of dust from the mixer by the dust suction pipe 7.

[0050] The connecting shell 3 is connected to the inner cavity of the feeding shell 2. A flange 4 is installed on the side surface of the connecting shell 3. The connecting shell 3 is connected to the internal mixer by bolts.

[0051] The feeding assembly includes an electric push rod 61, a placement shell 62, and a feeding head 63. The placement shell 62 is connected to the side surface of the feeding shell 2. The electric push rod 61 is fixedly installed on the side surface of the placement shell 62. The output end of the electric push rod 61 is fixedly connected to the feeding head 63. The feeding head 63 can slide in the inner cavity of the placement shell 62 and the inner cavity of the feeding shell 2.

[0052] Start the electric push rod 61, which pushes the pusher head 63 placed in the placement shell 62 out, so that the pusher head 63 can push the material in the feeding shell 2 into the internal mixer, making the material easy to reuse and ensuring the stability of the material ratio.

[0053] A sealing mechanism 5 is installed on the side surface of the connecting shell 3. The sealing mechanism 5 includes a fixing frame 51, a hydraulic cylinder 54 and a sealing plate 55. The fixing frame 51 is fixedly installed on the side surface of the connecting shell 3. The hydraulic cylinder 54 is fixedly installed on the front side of the fixing frame 51. A push plate 52 is fixedly connected to the output end of the hydraulic cylinder 54. The sealing plate 55 is fixedly connected to the side surface of the push plate 52.

[0054] Start the hydraulic cylinder 54, which pushes the fixedly connected push plate 52 to move. The push plate 52 drives the connected sealing plate 55 to slide, realizing the automatic opening and closing of the connecting shell 3, which facilitates material feeding control.

[0055] The sealing plate 55 is slidably connected to the side surface of the communicating shell 3, and the sealing plate 55 is used to seal the inner cavity of the communicating shell 3.

[0057] The filtration mechanism 8 includes a filter housing 85, a filter screen 86, and a cleaning component. The filter housing 85 is fixedly connected to the bottom surface of the cover 12. The filter screen 86 is installed on the surface of the filter housing 85, and the brush surface of the cleaning component is provided on the outer side of the filter screen 86.

[0058] The cleaning assembly includes a servo motor 81, a stirring shaft 82, and a cleaning brush 84. The servo motor 81 is fixedly mounted on the top side surface of the housing cover 12. The output end of the servo motor 81 is connected to the stirring shaft 82. The bottom end of the stirring shaft 82 penetrates the bottom side surface of the filter housing 85. A connecting frame 83 is fixedly connected to the bottom side surface of the stirring shaft 82. The cleaning brush 84 is fixedly connected to the end of the connecting frame 83.

[0059] When dusty gas enters the housing 11, it is filtered by the filter screen 86, which intercepts the dust material on the outside of the filter screen 86. The servo motor 81 drives the stirring shaft 82 to rotate, which in turn drives the connecting frame 83 fixedly connected to the bottom to rotate. The connecting frame 83 drives the fixedly connected cleaning brush 84 to rotate, so that the cleaning brush 84 can clean the dust material on the surface of the filter screen 86. The dust material that is cleaned off is collected in the feeding shell 2 for subsequent feeding.

[0060] The length of the cleaning brush 84 is greater than the height of the filter screen 86, and the bristles of the cleaning brush 84 are in contact with the outer surface of the filter screen 86.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
