Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a fixed bed reactor. Background Art

[0002] A fixed bed reactor is a common chemical reaction device. Its working principle is based on the design of the fixed bed and the chemical changes produced by the reactants in the fixed bed. In a fixed bed reactor, the reactants flow through a catalyst bed fixed in the reactor. The catalyst bed is usually composed of uniformly dispersed catalyst particles. When the reactants pass through the bed, the catalyst interacts with the reactants, triggering a chemical reaction.

[0003] In the prior art, a fixed bed reactor is proposed in a Chinese patent document with publication number CN219377074U. When it is necessary to clean impurities on the filter plate, the application pulls the insertion rod to move it and separate it from the filter plate. At this time, the filter plate loses its limit, making it easy for the operator to pull the filter plate out from the inside of the reactor body, and then to clean the impurities on the filter plate. Therefore, the filter plate is more convenient to clean. The above patent document is consistent with the prior art in that: when cleaning impurities on the filter plate, the filter plate needs to be pulled out from the device body and then inserted into the device body after cleaning. This cleaning method takes a long time to operate, and the filter plate cannot filter impurities in the input material during cleaning, thereby reducing the working efficiency of the reactor. Furthermore, we disclose a fixed bed reactor to meet the actual demand for the traditional fixed bed reactor that takes a long time to clean impurities on the filter plate and reduces the working efficiency. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a fixed bed reactor to solve the problem that the cleaning of impurities on the filter plate of the traditional fixed bed reactor takes a long time and reduces the working efficiency.

A capture and cleaning assembly for intercepting impurities in the material entering the body 1 is arranged at the lower end of the feed cylinder 2 inside the body 1. The capture and cleaning assembly comprises four filter cylinders 4, and a cross 7 is fixedly connected between the four filter cylinders 4.

When the impurities on the rotating plate 13 need to be cleaned, a structure for quickly cleaning the impurities is provided. The filter cartridge 4 is driven to rotate by the cross 7 by rotating the rotating rod 6. The filter cartridge 4 at the lower end of the feed cylinder 2 rotates. When the filter cartridge 4 rotates to the upper end of the rectangular design of the special-shaped groove 9, the rotating plate 13 rotates. The impurities on the rotating plate 13 fall into the discharge pipe 18 due to the influence of gravity to complete the cleaning of the impurities. After the rotating rod 6 rotates ninety degrees, another filter cartridge 4 will replace the previous filter cartridge 4 to capture the impurities in the material. Through this structural design, the impact on the operation of the reactor during impurity cleaning is minimized, the impurity cleaning time is reduced, and the working efficiency of the fixed bed reactor is improved.

The lower end of the discharge pipe 18 is rotatably connected to a door panel 20, and a handle for facilitating the rotation of the door panel 20 is fixedly connected to the middle of one end surface of the door panel 20. The middle of the inner wall of the door panel 20 is fixed A third telescopic spring 19 is fixedly connected, and one end of the third telescopic spring 19 away from the door panel 20 is fixedly connected to the discharge pipe 18.

When it is necessary to clean the impurities on the rotating plate 13, a structure for quickly cleaning the impurities is provided. The rotating rod 6 is rotated by the handle to drive the four filter cartridges 4 to rotate using the cross 7. When the filter cartridge 4 rotates to the upper end of the rectangular design of the special-shaped groove 9, the rotating plate 13 is caused to rotate along one side of the filter cartridge 4 by the action of the first telescopic spring 10. The impurities on the rotating plate 13 are affected by gravity and fall from the circular hole at one end of the special-shaped groove 9 to the discharge pipe 18 to complete the cleaning of the impurities. The tail end of the discharge pipe 18 is rotatably connected to the door panel 20 through the third telescopic spring 19. When in use, the door panel 20 is in a closed state, which improves the The sealing of the reactor, when the cross 7 continues to rotate, one end of the rotating plate 13 contacts the guide plate 8 on the special-shaped groove 9. Since the guide plate 8 is inclined, the continuous rotation will drive the rotating plate 13 to complete the closing, which is convenient for the next filtering work. Every time the rotating rod 6 rotates ninety degrees, another filter cartridge 4 will replace the previous filter cartridge 4 to capture impurities in the material. The upper end of the lower plate 16 is slidably connected with the ball head rod 15 through the second telescopic spring 17.
