Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a dust removal device for the filling port of a styrene reactor. Background Technology

[0002] Styrene production typically involves the use of reaction vessels. In existing reaction vessels, the required powdered material is fed through a filling port during styrene processing. This filling port is equipped with a puncture tube; after puncturing the bottom of the packaging bag, the powdered material enters the reaction vessel through the filling port. However, some of the powdered material is released after puncturing the packaging bag, polluting the workshop environment. Utility Model Content

[0003] The purpose of this invention is to provide a dust removal device for the filling port of a styrene reactor, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a dust collection box, the lower end of which is open and covers the filling port. The bottom of the dust collection box is sealed to the filling port platform. The filling port is installed on the reactor and is hinged to a sealing cover. Multiple ventilation openings are provided on the side of the dust collection box above the filling port, and these openings are connected to a dust collector via suction pipes. A door is provided on the side of the dust collection box at the filling port.

[0005] Furthermore, a funnel is installed at the upper end of the dust collection box, and the funnel is connected to the filling port.

[0006] Furthermore, it also includes a cover-opening mechanism, which is connected to the sealing cover.

[0007] Furthermore, the opening mechanism includes a support frame, a cylinder, a fixed base, and a traction rope. The cylinder is mounted on the support frame, the output end of the cylinder is connected to the fixed base, one end of the traction rope is connected to the fixed base, and the other end of the traction rope is connected to the sealing cover.

[0008] Furthermore, an isolation plate is provided inside the dust collection box and directly above the sealing cover, the isolation plate separating the cover opening mechanism.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention incorporates a dust collection box. When feeding material into a styrene reactor, the box door and sealing cover are opened, and then the box door is closed. The powdery material enters the styrene reactor through the upper opening of the dust collection box and the filling port. Simultaneously, the powdery material floating in the dust collection box enters the dust collector through the suction pipe at the filling port. After feeding is completed, the sealing cover and box door are closed, thus preventing the powdery material from floating out to the outside and polluting the workshop environment.

Support frame; 11. Cylinder; 12. Fixing base; 13. Traction rope; 14. Isolation plate. Detailed Implementation

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0016] Example: Please refer to Figure 1-2 A dust removal device for the filling port of a styrene reactor includes a dust collection box 4, the lower end of which is open and covers the filling port 2. The bottom of the dust collection box 4 is sealed to the platform of the filling port 2. A funnel 8 is installed at the upper end of the dust collection box 4, and the funnel 8 is connected to the filling port 2, allowing powdery materials to be discharged. The filling port 2 is installed on the reactor 1 and is hinged to a sealing cover 3. Multiple ventilation openings 5 ​​are provided on the side of the dust collection box 4 above the filling port 2. The ventilation openings 5 ​​are connected to a dust collector via a suction pipe 6. The dust collector is existing technology and will not be described in detail. When feeding materials into the styrene reactor 1, the sealing cover 3 is opened, and the powdery materials enter the styrene reactor 1 through the dust collection box 4 and the filling port 2. At the same time, the powdery materials floating in the dust collection box 4 above the filling port 2 enter the dust collector through the suction pipe 6. After feeding is completed, the sealing cover 3 is closed, thus preventing the powdery materials from floating out of the environment and polluting the workshop.

[0017] A door 7 is provided on the side of the dust collector 4, located at the filling port 2, for easy closing and opening of the sealing cover 3 of the filling port 2. It also includes a cover opening mechanism 9, which is connected to the sealing cover 3. The cover opening mechanism 9 includes a support frame 10, a cylinder 11, a fixed base 12, and a traction rope 13. The cylinder 11 is mounted on the support frame 10, and its output end is connected to the fixed base 12. One end of the traction rope 13 is connected to the fixed base 12, and the other end is connected to the sealing cover 3. When the sealing cover 3 is closed, the traction rope 13 is slack. When the sealing cover 3 needs to be opened, the cylinder 11 retracts, tightening the traction rope 13, thereby opening the sealing cover 3. This eliminates the need for manual operation, allowing the sealing cover 3 to be quickly closed after feeding, preventing the powdery material in the styrene reactor 1 from escaping. An isolation plate 14 is provided inside the dust collector 4, directly above the sealing cover 3. The isolation plate 14 separates the cover opening mechanism 9, ensuring that feeding does not affect the cover opening mechanism 9.

[0018] The working principle of this embodiment is as follows: When the material is fed into the styrene reactor 1, the cylinder 11 is started. The cylinder 11 retracts and drives the fixed seat 12 to move upward. The traction rope 13 is pulled, thereby opening the sealing cover 3 and then closing the box door 7. Then the feeding begins, and the dust collector is started at the same time. The powdery material floating in the dust collection box 4 enters the dust collector through the dust suction pipe 6. After the feeding is completed, the cylinder 11 is started. The cylinder 11 extends and drives the fixed seat 12 to move downward. The traction rope 13 is in a slack state, thereby closing the sealing cover 3. This is how it works.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "upper," "lower," "left," "right," "front," "back," and similar expressions used in this document are for illustrative purposes only.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
