Epichlorohydrin production equipment is an equipment system used to manufacture epichlorohydrin. The reactor is an indispensable part of epichlorohydrin production equipment. Certain impurities will be generated in the production process of epichlorohydrin. These impurities adhere to the inner wall of the reactor and need to be cleaned.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figure 1-8 As shown, a cleaning device for epichlorohydrin production equipment according to an embodiment of the present invention comprises a reactor body 1, a feed pipe 2 fixedly connected to one side of the outer peripheral surface of the reactor body 1, a stirring rod 3 rotatably connected to the middle position of the reactor body 1, and a friction cleaning mechanism for cleaning the inner wall of the reactor body 1;

[0032] The friction cleaning mechanism includes a scraping component, a spray component and a driving component;

[0033] During cleaning, the feed pipe 2 and the discharge pipe at the bottom of the reactor body 1 are first sealed. The scraping assembly can be used to clean and detach impurities attached to the inside of the reactor body 1. The spray assembly can evenly spray cleaning liquid on the inner wall of the reactor body 1 during cleaning by the scraping assembly to improve the cleaning effect of the inner wall of the reactor body 1. The driving assembly can drive the stirring rod 3 to rotate, so that the material inside the reactor body 1 can be stirred when it is needed to be mixed. The scraping assembly and the spray assembly can also be driven to work by the stirring rod 3 when the inner wall of the reactor body 1 needs to be cleaned.

[0034] Please refer to Figure 1-7 As shown, the scraping assembly includes a sleeve plate 4 fixedly sleeved on the outer circumference of the stirring rod 3, a tooth seat 5 arranged at the top of the inner cavity surface of the reactor body 1, a slot 6 opened on the surface of one end of the sleeve plate 4, a socket 7 arranged at the top position of the tooth seat 5, a guide component acting on the socket 7, a movable shaft 10 rotatably connected to the bottom position of the socket 7, a first gear 11 fixedly sleeved at the top position of the outer circumference of the movable shaft 10, scraping strips 12 fixed at the bottom position of the outer circumference of the movable shaft 10 in an equidistantly distributed manner, and a scraper 13 fixed at the bottom position of the stirring rod 3;

[0035] One end of the socket 7 extends to the inside of the slot 6 and contacts the inner surface of the slot 6. The first gear 11 is meshed and connected with the middle position of the inner circumference of the gear holder 5. The bottom surface of the scraper 13 is arc-shaped.

[0036] When the stirring rod 3 rotates, it can drive the sleeve plate 4 to rotate so that the socket 7 makes a circular motion under the interference of the slot 6 on the socket 7. The guide component can limit the motion trajectory of the socket 7 and support the socket 7 in this process. In this process, the first gear 11 will mesh with the inner circumferential surface of the gear seat 5, so that the movable shaft 10 can rotate while making a circular motion with the socket 7, so that the scraper 12 can make a circular motion around the movable shaft 10 while moving along the active trajectory of the socket 7, so that it can rub against the inner circumferential surface of the reactor body 1, and under the centrifugal force of the scraper 12, the scraped impurities are separated from the inner circumferential surface of the reactor body 1, thereby improving the cleaning effect of the inner circumferential surface of the reactor body 1. During the rotation of the stirring rod 3, the scraper 13 can be directly driven to rotate, so that the scraper 13 fits the arc surface at the bottom of the reactor body 1 to play a cleaning role.

[0037] Please refer to Figure 1-8 As shown, the guide component includes an annular groove 8 with a T-shaped cross section opened at the top of the gear seat 5 and a positioning block 9 with a T-shaped cross section slidably inserted in the inner cavity of the annular groove 8, and the bottom of the socket 7 is fixed to the surface of the top of the annular groove 8;

[0038] Due to the vertical interference between the inner cavity of the annular groove 8 and the positioning block 9, the positioning block 9 cannot be displaced in the vertical direction, thereby supporting the socket 7. In addition, due to the interference between the circumferential surface of the inner cavity of the annular groove 8 and the contact surface of the positioning block 9, the motion trajectory of the socket 7 when it makes a circular motion can be limited, making its movement more stable.

[0039] Please refer to Figure 1-8As shown, the driving assembly includes a motor 24 fixed to the top of the reactor body 1 near the stirring rod 3 and a second gear 25 fixed to the outer circumference of the stirring rod 3 and the outer circumference of the motor 24, and the two second gears 25 are meshedly connected;

[0040] When the motor 24 is started, one of the second gears 25 can rotate, so that the other second gear 25 can drive the stirring rod 3 to rotate due to the meshing action between the two second gears 25. When the inside of the reactor body 1 needs to be cleaned, the output end of the motor 24 can be controlled to have a lower rotation speed than when it is placed in the inner cavity of the reactor body 1 to stir and mix the materials.

[0041] Please refer to Figure 1-8 As shown, the spray assembly includes a liquid storage tank 17 opened inside the stirring rod 3, a plurality of spray cylinders 14 arranged at both sides of the stirring rod 3, a connecting pipe 15 connected and fixed to the top of the spray cylinder 14 and arranged obliquely, a piston plate 18 slidably inserted in the inner cavity of the spray cylinder 14, a connecting rod 19 fixed to the surface of one side of the piston plate 18 and arranged in an L shape, a movable plate 16 arranged at a middle position between the two groups of spray cylinders 14 and the stirring rod 3, a plurality of sliding rods 20 arranged at one end of the movable plate 16, an abutment seat 21 fixed to the surface of the movable plate 16, a support rod 22 arranged at the bottom position of the gear seat 5 and arranged in an equidistant and surrounding distribution, an abutment block 23 fixed to the surface of one side of the support rod 22, and a spring telescopic rod 30 fixed to the piston plate 18 at a side away from the connecting rod 19, and one side of the connecting pipe 15 is connected and fixed to the inside of the liquid storage tank 17;

[0042] The two sides of the sliding rod 20 are fixed to the surfaces of the adjacent spray barrel 14 and the stirring rod 3, the connecting rod 19 is slidably connected to the adjacent spray barrel 14, the surface of the connecting rod 19 extending out of the outer part of the spray barrel 14 is fixed to the surface of the movable plate 16, a one-way valve is installed at the water outlet of the spray barrel 14 and the position of the connecting pipe 15 close to the inner cavity of the spray barrel 14, the surface of one end of the resistance seat 21 is inclined, the surface of one end of the resistance block 23 is inclined, and the side of the spring telescopic rod 30 away from the piston plate 18 is fixed to the inner cavity surface of the spray barrel 14;

[0043] By connecting a pipe to the outlet pipe of the pump body to extend it to the inside of the liquid storage tank 17, a storage device storing cleaning liquid is connected to the water inlet end of the pump body, so that the cleaning liquid can be added to the inside of the liquid storage tank 17, and the pump body is intermittently controlled so that the cleaning liquid is placed in the inner cavity of the liquid storage tank 17. The height position is always higher than the spray barrel 14 at the top position. When the stirring rod 3 rotates, the movable plate 16 and the spray barrel 14 will perform a circular motion synchronously under the connection between the sliding rod 20 and the connecting rod 19. The piston plate 18 in the inner cavity of the spray barrel 14 is not in contact with the seat 21. When the agitator 3 drives the agitator 21 to make a circular motion, each time the agitator 3 drives the agitator 21 to make a circular motion and agitates a fixed agitator 23, the movable plate 16 moves away from the adjacent spray barrel 14 under the connecting action of the connecting rod 19, so that the piston plate 18 moves towards the agitator 3 under the connecting action of the connecting rod 19, so that the air pressure in the inner cavity of the spray barrel 14 changes, so that the cleaning liquid in the inner cavity of the liquid storage tank 17 can pass through the connecting pipe. 15 enters the inner cavity position of each spray cylinder 14. During this process, the spring telescopic rod 30 will be in a stretched state, so that when the abutment seat 21 is away from each abutment block 23, the piston plate 18 can be driven to reset under the action of the spring telescopic rod 30, so that the air pressure in the inner cavity of the spray cylinder 14 changes again, so that the liquid in the inner cavity of the spray cylinder 14 can be sprayed from the spray cylinder 14 to the inner wall of the reactor body 1. In this process, the setting of the one-way valve at the water outlet of the connecting pipe 15 and the spray cylinder 14 makes the water outlet of the spray cylinder 14 The opening can only spray liquid to the outside, and the liquid in the inner cavity of the spray barrel 14 is difficult to enter the interior of the connecting pipe 15, so that while the scraping component is cleaning, the cleaning liquid can be sprayed to the inner wall of the reactor body 1 to improve the cleaning effect of the inner wall of the reactor body 1, and the cleaning liquid can be evenly sprayed to the inner wall of the reactor body 1 without using too much cleaning liquid, thereby reducing the use of cleaning liquid and saving costs. After the cleaning is completed, the sealing state of the discharge pipe at the bottom of the reactor body 1 is cancelled, so that the cleaning liquid is discharged through the discharge pipe along with the impurities under the action of gravity.

[0044] Embodiment 2

[0045] Please refer to Figure 1-8 As shown, when the stirring rod 3 needs to stir and mix the raw materials required for the production of epichlorohydrin entering the reactor body 1, the friction between the scraping component and the inner cavity of the reactor body 1 and the influence of the spray component will reduce the rotation speed of the stirring rod 3, and when the rotation speed of the stirring rod 3 is too fast, the scraping component and the spray component are easily damaged.

[0046] To this end, the friction cleaning mechanism also includes a vertical adjustment assembly, which includes a threaded rod 26 threadedly connected to one side of the top of the reactor body 1, a limiting rod 27 inserted and slidably inserted on the other side of the top of the reactor body 1, a connecting ring 28 fixed at the middle position of the plurality of support rods 22, and support columns 29 evenly fixed to the top of the connecting ring 28 and arranged in an equidistant and surrounding manner;

[0047] The bottom of the threaded rod 26 is rotatably connected to the surface of one side of the top of the gear holder 5, the bottom of the limiting rod 27 is fixed to the other side of the top surface of the gear holder 5, the top of the support column 29 is fixed to the surface of the bottom of the gear holder 5, and the top of the reactor body 1 is a transparent material component;

[0048] When the inside of the reactor body 1 needs to react again after cleaning, the threaded rod 26 is rotated to make the tooth seat 5 move in the vertical direction under the cooperation of the threaded structure between the inner wall of the reactor body 1 and the guiding action of the limiting rod 27, so that the socket 7 is separated from the sleeve plate 4, and the tooth seat 5 will drive the multiple support rods 22 and the interference block 23 to move vertically upward for a certain distance, so that the stirring rod 3 will not affect the stirring effect of the stirring rod 3 when rotating and stirring, and because the top of the reactor body 1 is a transparent material component, the inside of the reactor body 1 can be observed. When it is necessary to clean the inner wall of the reactor body 1 here, the sleeve plate 4 is adjusted to the bottom position of the socket 7 by the driving component, so that when the threaded rod 26 is rotated in the opposite direction, the socket 7 can move vertically upward and re-insert with the sleeve plate 4 and the interference block 23 can return to the height position that can interfere with the interference seat 21.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
