[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Example:

[0032] A dust-free feeding device for silicone rubber filler, such as Figure 1 As shown, it includes a reactor 1, and a feed port 11 and a return port 12 are provided on the top of the reactor 1, and the silicone filler enters the reactor body from these two ports. A feed funnel 2 is fixedly connected to the top of the feed port 11, and the outer wall of the bottom of the feed funnel 2 abuts against the inner wall of the feed port 11, so that the feed funnel 2 is connected to the inner cavity of the feed port 11, which is convenient for adding fillers into the reactor 1. In order to absorb the dust generated in the feed funnel 2 when adding fillers, a dust collecting component 3 is installed above the feed funnel 2. The dust collecting component 3 is also connected to the return port 12 so that the collected filler dust can be added back to the reactor 1. In addition, a support frame 4 is provided on the outside of the reactor 1 for stably mounting the dust collecting component 3. When the filler is added into the reactor 1 through the feed funnel 2, the dust collecting component 3 starts to absorb the generated dust and collect the dust. Then the filler dust returns to the reactor 1 through the return port 12 to achieve dust-free feeding, so as to reduce the impact of dust on the environment and personnel health.

[0033] Specifically, Figure 1-2As shown, the dust collection assembly 3 includes a dust hood 31, a guide pipe 32, a dust box 33 and a fan 34. The dust hood 31 is placed above the feed hopper 2, and the guide pipe 32 connects the dust hood 31 and the dust box 33, and the bottom of the guide pipe 32 is effectively supported by a support seat 41 fixed on the support frame 4 to ensure the stability of the support pipe, so that the dust absorbed from the dust hood 31 can pass into the dust box 33. The fan 34 is connected to one side of the dust box 33 to provide power for dust collection. In addition, a flexible connecting pipe 36 is fixedly connected between the dust hood 31 and the guide pipe 32 through a fixing member, which is used to increase the flexibility of the dust hood 31, so that the dust hood 31 can be moved or adjusted in position and direction within a certain range, further improving the dust collection effect. Among them, in this embodiment, the flexible connecting pipe 36 is a corrugated pipe, and the fixing member is a clamp.

[0034] like Figure 1-3 As shown, in this embodiment, the diameter of the top of the feed hopper 2 is larger than the diameter of the feed port 11, so that when adding fillers, the fillers can enter the reactor 1 more smoothly from the feed hopper 2. At the same time, the diameter of the dust hood 31 close to the side of the feed hopper 2 is larger than the diameter of the top of the feed hopper 2, and the dust hood 31 can cover the feed hopper 2 more comprehensively, improve the collection efficiency of dust, and reduce the impact of dust on the environment.

[0035] like Figure 1-2 As shown, in this embodiment, a return pipe 35 is also provided at the bottom of the dust box 33, and one end of the return pipe 35 away from the dust box 33 is connected to the return port 12. The dust filler collected in the dust box 33 can be re-added into the reactor 1 from the return port 12 to reduce the error of the added amount caused by dust and more accurately control the added amount of filler.

[0036] In addition, if Figure 2 As shown, in order to ensure the normal operation of the fan 34, a filter 37 is installed at the connection between the dust box 33 and the fan 34. When the fan 34 is started, the filter 37 can effectively block the filler dust in the dust box 33, reduce the phenomenon that the dust enters the fan 34 and causes damage to the fan 34, and extend the service life of the fan 34.

[0037] like Figure 3 As shown, a first valve 111 is provided in the feed port 11, and a second valve 121 is provided in the return port 12. When adding fillers, the first valve 111 and the second valve 121 are opened so that the fillers can enter the reactor 1 from the feed port 11 and the return port 12. After the fillers are added, the first valve 111 and the second valve 121 need to be closed to maintain the sealing of the reactor 1.

[0038] Working principle: When adding fillers, open the first valve 111, and add the fillers to the reactor 1 through the feed hopper 2. At this time, due to the addition of fillers, dust will be generated in the feed hopper 2. Start the fan 34, and suck the generated dust into the dust box 33 through the dust hood 31 and the guide pipe 32. The filter 37 will prevent the dust from entering the fan 34 to protect the normal operation of the fan 34. When the dust in the dust box 33 accumulates to a certain amount, open the second valve 121, and add the dust back to the reactor 1 through the return pipe 35. When the fillers are added, close the first valve 111 and the second valve 121, stop the fan 34, and complete a filler addition operation. The dust generated during the feeding process is effectively absorbed and processed by the dust collection component 3, which protects the health of the staff and improves the cleanliness of the production environment. At the same time, the collected dust is added back to the reactor 1 through the return pipe 35, which reduces the waste of fillers and improves production efficiency.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
