Description

Technical Field

[0001] This utility model relates to a dust-free discharge device for a double-cone rotary vacuum reactor, belonging to the field of chlorosulfonated polyethylene manufacturing technology. Background Technology

[0002] The manufacturing process of chlorosulfonated polyethylene typically employs a gas-solid phase reaction method. This method involves adding chlorinated polyethylene powder, an initiator, and an anti-adhesion agent into a double-cone rotary vacuum reactor. Stirring is then initiated, and the reactor is evacuated. Hot nitrogen is then introduced, followed by depressurization. This process is repeated several times. Finally, a mixture of chlorine and sulfur dioxide is introduced into the reactor. Under a certain pressure, the mixture is forced to penetrate deep into the chlorinated polyethylene to react, resulting in a uniform distribution of chlorosulfonyl groups in the product. This yields chlorosulfonated polyethylene with suitable basic and performance indicators.

[0003] Currently, the discharge method of the double-cone rotary vacuum reactor is as follows: a discharge valve is installed at the opposite end of the feed port of the double-cone rotary vacuum reactor. During discharge, the reactor is controlled to be suspended so that the discharge valve is vertically downward, and a ton bag is placed below the discharge port. During discharge, nitrogen gas is first used to pressurize the reactor to 0.02~0.08MPa, and then the discharge valve is opened. The material is then expelled into the ton bag by gravity and the internal pressure of the reactor.

[0004] The above-mentioned discharge method, based on practical experience, still has the following technical problems: During the discharge process, the material is easily dispersed into the air of the work area in the form of dust from the connection between the ton bag and the discharge port, and secondary dust is easily generated during the cleaning process, causing serious air pollution. There is also a risk of material leakage and loss during the discharge process, and it is also easy to cause material contamination problems.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a dust-free discharge device for a double-cone rotary vacuum reactor, ensuring that no dust or particulate matter is generated during discharge, while also reducing material loss and contamination.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A dust-free discharge device for a double-cone rotary vacuum reactor includes a dust removal hood, which is installed at the top of a rigid connecting pipe. The rigid connecting pipe is arranged vertically, and its side is connected to a lifting assembly. The lifting assembly can fasten the dust removal hood to the outlet end of the discharge valve at the bottom of the double-cone reactor. The dust removal hood has a conical hole inside, and an annular clamping cavity is provided around the conical hole. The annular clamping cavity and the conical hole are connected by a plurality of evenly distributed suction holes. A negative pressure connector connected to the annular clamping cavity is installed on the side of the annular clamping cavity.

[0009] Furthermore, the dust removal hood has stepped holes inside, and the dust removal hood is fastened to the top of the rigid connecting pipe through the stepped holes.

[0010] Furthermore, the negative pressure connector is externally connected to the dust collector via a pipeline.

[0011] Furthermore, the bottom discharge valve of the double cone reactor is provided with a feeding hole at the opposite end, and the double cone reactor is rotatably installed in the frame.

[0012] Furthermore, the lifting assembly includes two connecting rods arranged parallel to each other, one end of which is hinged to the outer wall of the rigid connecting pipe, and the other end of which is hinged to the inner side of the frame.

[0013] Furthermore, there is an inclined telescopic cylinder between the two connecting rods. The head of the telescopic cylinder is hinged to the lower connecting rod, and the tail of the telescopic cylinder is hinged to the inner side of the frame.

[0014] Furthermore, the bottom end of the rigid connecting pipe is connected to the top end of the flexible connecting pipe, and the bottom end of the flexible connecting pipe is fixedly installed on the sealing cover at the top of the hopper.

[0015] Furthermore, the bottom of the collecting hopper is connected to the input end of the conveying screw cylinder, and a waiting hopper is installed below the output end of the conveying screw cylinder, with a discharge port at the bottom of the waiting hopper.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] During discharge, the telescopic cylinder retracts, and under the stable support of the two connecting rods, it drives the rigid connecting pipe and the dust collector to rise steadily, so that the dust collector is fastened to the outlet end of the discharge valve. The chlorosulfonated polyethylene powder in the double cone reactor enters the waiting silo after passing through the rigid connecting pipe, the flexible connecting pipe, the collection hopper, and the conveying screw. The entire conveying process is fully enclosed, eliminating the generation of dust and reducing material loss and contamination.

[0018] This utility model has an air suction hole and an annular clamping cavity inside the dust removal hood. The annular clamping cavity is connected to the dust collector through a pipeline, which facilitates the extraction and absorption of dust and particulate matter that may be scattered from the connection gap, thereby further preventing the generation of dust and particulate matter.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
