Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment, and particularly relates to a knocking device for solving the blockage of a catalyst circulation system. Background Technique
[0002] The amount of dust generated by the catalyst circulation system will increase with the increase of the operation time of the device. The increase in the amount of catalyst dust leads to frequent situations where the system circulation is not smooth during the operation of the device, unable to ensure the stable operation of the device, and even the system may stop working and cannot operate smoothly. Since April 2023, the catalyst circulation system of a continuous reforming unit of a company in the industry has had the phenomenon of catalyst leg blockage 5 times in total, resulting in abnormalities in the catalyst circulation system and further leading to the interlock shutdown of the catalyst circulation system. Content of the Utility Model
[0003] The purpose of the utility model is to provide a knocking device for solving the blockage of a catalyst circulation system.
[0004] The utility model provides the following technical solutions:
[0005] The utility model provides a knocking device for solving the blockage of a catalyst circulation system, which includes a support frame. A speed reducer driven by a motor is fixed on the support frame. The output end of the speed reducer is a worm shaft. The worm shaft drives a transmission screw rod to move vertically up and down. A sliding plate is arranged at the lower end of the transmission screw rod, and an explosion-proof knocker is arranged horizontally on the sliding plate.
[0006] Further, the worm shaft is a hollow shaft, and a nut is embedded in its inner wall. The transmission screw rod is arranged in the nut.
[0007] Further, the support frame is a doorframe-shaped support frame. Limiting card slots are opened on both support arms of the doorframe-shaped support frame. The sliding plate moves up and down in the limiting card slots depending on the transmission screw rod.
[0008] Further, it also includes a plurality of temperature sensors arranged on the catalyst leg of the reforming reactor. The temperature sensors transmit the collected temperature signals to a central control, and the central control controls the operation of the motor.
[0009] Further, a protection plate is arranged on the catalyst leg.
[0010] Compared with the prior art, the utility model senses the temperature change of the catalyst leg through a temperature sensor (the temperature at the blocked part will decrease), and the central control confirms the blocked part according to the temperature change and starts the motor to transmit power to the reducer to drive the transmission screw to move up and down, until the explosion-proof knocker reaches the blocked part and knocks on the protection plate to effectively shake off the catalyst blocking the catalyst leg. The utility model can timely knock on the blocked position by capturing the temperature, avoiding material blockage; at the same time, the self-knocking can effectively save labor input.

[0014] In the following embodiments, the model of the explosion-proof knocker used is ZH-60TS.
[0015] In an embodiment of the utility model, a knocking device for solving the blockage of the catalyst circulation system includes a support frame 1, on which a reducer 3 driven by a motor 2 is fixed. The output end of the reducer 3 is a worm shaft, and the worm shaft drives a transmission screw 4 to move vertically up and down. A sliding plate 5 is arranged at the lower end of the transmission screw 4, and an explosion-proof knocker 6 is horizontally arranged on the sliding plate 5; the motor 2 drives the worm shaft of the reducer 3 to rotate, and the worm shaft drives the transmission screw 4 to move up and down, and then the transmission screw 4 drives the explosion-proof knocker 6 on the sliding plate to move up and down, and the blocked position is knocked off by the explosion-proof knocker 6.
[0016] In the above embodiment, the transmission screw 4 and the sliding plate 5 are movably connected (such as ball connection, clamping connection, etc.); it is ensured that when the transmission screw 4 rotates, the sliding plate 5 will not rotate along with it.
[0017] In an embodiment of the utility model, the worm shaft is a hollow shaft, and a nut is embedded in its inner wall, and the transmission screw 4 is arranged in the nut; the up and down movement of the transmission screw 4 is realized as the nut rotates.
[0018] In an embodiment of the present utility model, the support frame 1 is a doorframe-shaped support frame. Restricting slots 11 are provided on both support arms of the doorframe-shaped support frame 1. The sliding plate 5 moves up and down in the restricting slots 11 by relying on the transmission screw 4; the sliding plate 5 moves up and down in the restricting slots 11 to ensure that the explosion-proof hammer 6 always faces the reforming reactor 7.
[0019] In an embodiment of the present utility model, it further includes a plurality of temperature sensors 8 provided on the catalyst leg 71 of the reforming reactor 7. The temperature sensors 8 transmit the collected temperature signals to a central control 9, and the central control 9 controls the motor 2 to work; by the temperature sensors 8 sensing the temperature change of the leg (the temperature of the blocked part will decrease), the central control 9 confirms the blocked part according to the temperature change and starts the motor 2 to transmit power to the speed reducer 3 to drive the transmission screw 4 to move up and down.
[0020] In the above embodiment, a protective plate 72 is provided on the catalyst leg 71; to reinforce and protect the catalyst leg 71.
[0021] In practical applications, by the temperature sensors sensing the temperature change of the leg (the temperature of the blocked part will decrease), the central control confirms the blocked part according to the temperature change and starts the motor to transmit power to the speed reducer to drive the transmission screw to move up and down until the explosion-proof hammer reaches the blocked part and knocks on the protective plate to effectively shake off the catalyst blocking the catalyst leg.
