[0033] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0034] The utility model provides a 2-chloro-5-chloromethylpyridine transfer device. Figure 1 To Attachment Figure 4 It can be seen that the vehicle frame 10, the tank body 11, the connecting pipe 15, the hook 18 and the driving assembly 20 are included. The tank body 11 for holding materials is horizontally arranged on the vehicle frame 10, the top of the tank body 11 is provided with a liquid inlet pipe 12, the bottom of the tank body 11 is provided with a liquid outlet pipe 13, and a fixing ring 14 is arranged inside the liquid inlet pipe 12; the connecting pipe 15 is coaxially arranged with the liquid inlet pipe 12, the upper end of the connecting pipe 15 extends out of the upper end of the liquid inlet pipe 12 and is connected to the discharge port of the production material device, the lower end of the connecting pipe 15 extends into the fixing ring 14, and an annular groove 16 is arranged on the outer side of the connecting pipe 15; a plurality of fixing seats 17 are arranged on the upper surface of the fixing ring 14, and are evenly spaced along the circumference thereof. The tank body 11 is evenly distributed, and each fixing seat 17 is rotatably provided with a hook 18, and the hook 18 is adapted to the slot provided on the bottom surface of the annular groove 16; a plurality of driving components 20 are respectively corresponding to and connected with the plurality of hooks 18, and the driving components 20 are used to drive the hooks 18 to engage or disengage with the slot; the nozzle 31 is horizontally arranged in the tank body 11, and a plurality of nozzles 32 are arranged in the length direction of the nozzle 31, and the nozzles 32 face the bottom of the tank body 11, and one end of the nozzle 31 is connected to the liquid storage tank 33 provided on the outside of the tank body 11 through a water pipe. The inner surface of the tank body 11 is coated with a corrosion-resistant coating. The outer surface of the tank body 11 is provided with a jacket 34, and an electric heating wire is provided in the jacket 34. Four casters 35 with braking function are respectively provided at the four corners below the frame 10. A one-way valve 37 is provided in the liquid outlet pipe 13. A sealing cover 38 is also provided at the top of the liquid inlet pipe 12. The inner wall of the sealing cover 38 is threadedly connected to the outer surface of the top of the liquid inlet pipe 12. The sealing cover 38 is connected to one side of the liquid inlet pipe 12 through a connecting line.

[0035] In order to facilitate the transfer of 2-chloro-5-chloromethylpyridine, the tank 11 containing the material is set on the frame 10, and four casters 35 with braking functions are respectively installed at the four corners of the bottom of the frame 10. When receiving the material, the braking function of the casters 35 is turned on and the transfer device will not move. When the material needs to be transferred, the braking function of the casters 35 is turned off, and the operator can easily push the frame 10 to push the transfer device to the required location. When receiving the material, the upper end of the connecting pipe 15 is connected to the discharge port of the device for producing the material, and the lower end of the connecting pipe 15 extends into the liquid inlet pipe 12. The driving component 20 drives the hook 18 to rotate, and the hook 18 is clamped with the clamping groove set on the outer side of the connecting pipe 15. The connecting pipe 15 is fixed in the liquid inlet pipe 12. The switch at the discharge port is turned on, and the material in the production device flows into the tank 11 through the connecting pipe 15 and the liquid inlet pipe 12 in turn. When the material fills the tank 11, the switch of the discharge port is closed, and the driving component 20 is operated to drive the hook 18 to rotate. The hook 18 rotates in the opposite direction until the hook 18 is disengaged from the slot, and the connecting pipe 15 is pulled out of the liquid inlet pipe 12. The snap-on design can ensure the firmness and convenience of the connection. The sealing cover 38 is screwed on the top of the liquid inlet pipe 12. On the one hand, it can maintain the sealing of the top of the liquid inlet pipe 12 to prevent external impurities from entering the tank body 11. On the other hand, it can prevent the toxicity of the material from volatilizing. By applying a corrosion-resistant coating inside the tank body 11, the inner wall of the tank body 11 can be protected from erosion by the material contained therein, thereby improving the service life and durability of the tank body 11. The one-way valve 37 is set in the liquid outlet pipe 13 to effectively prevent the backflow of the material, ensuring that the liquid material can only flow in one direction, thereby ensuring the normal operation and safety of the transfer device.

[0036] The electric heating wire in the jacket 34 keeps the 2-chloro-5-chloromethylpyridine in the tank body 11 warm, so that the 2-chloro-5-chloromethylpyridine is always in liquid state during the transfer process. During the entire transfer process, the 2-chloro-5-chloromethylpyridine will not come into contact with the workers, thereby avoiding harm to the workers by the 2-chloro-5-chloromethylpyridine during the transfer process.

[0037] When the inner wall of the tank 11 needs to be cleaned, the liquid storage tank 33 provides cleaning liquid to the nozzle 31, and the cleaning liquid is sprayed from the nozzle 32. Under the impact of the cleaning liquid, the inner wall of the tank 11 is cleaned, and the cleaning liquid after washing is discharged through the liquid outlet pipe 13. This cleaning method is simple and fast, and has great promotion value.

[0038] As an embodiment, according to the attached Figure 2 To Attachment Figure 3It can be seen that the driving assembly 20 includes a rotating shaft 21, a gear 22, a rack 23 and a translation mechanism 24. The rotating shaft 21 is horizontally and rotatably arranged on the fixed seat 17 of the hollow structure, and the end of the rotating shaft 21 is connected to the lower end of the hook 18; the rotating shaft 21 in the fixed seat 17 is provided with a gear 22; the rack 23 is vertically arranged in the fixed seat 17 and meshes with the gear 22; the translation mechanism 24 is connected to the rack 23, and is used to drive the rack 23 to move back and forth.

[0039] When the translation mechanism 24 drives the rack 23 to rise, it drives the gear 22 and the rotating shaft 21 to rotate counterclockwise, and the rotating shaft 21 drives the hook 18 connected thereto to rotate counterclockwise. When the hook 18 is embedded in the slot, the translation mechanism 24 stops moving, and the connecting tube 15 is fixed in the liquid inlet tube 12 by the action of multiple hooks 18 and the slots. When the translation mechanism 24 drives the rack 23 to descend, it drives the gear 22 and the rotating shaft 21 to rotate clockwise, and the rotating shaft 21 drives the hook 18 to rotate clockwise until the hook 18 is separated from the slot. The translation mechanism 24 stops moving, and the connecting tube 15 is pulled out upward, and the connecting tube 15 is easily taken out. The connection and removal of the connecting tube 15 are realized through the cooperation of the driving component 20 and the slot of the hook 18, thereby improving the safety and convenience of operation.

[0040] In this embodiment, according to the specification Figure 2 To Attachment Figure 3 It can be seen that the translation mechanism 24 includes: a first slider 241 and a second slider 242, which are respectively arranged at the upper and lower ends of the rack 23, and the two sliders are slidably connected and adapted to the inner wall of the fixed seat 17. An air outlet 243 is arranged on the fixed seat 17 above the first slider 241, and an air inlet 244 arranged on the fixed seat 17 below the second slider 242 is connected to the air pump. When the air pump inflates or inhales air into the fixed seat 17, the rack 23 therebetween can be driven to rise or fall through the first slider 241 and the second slider 242.

[0041] Because the air pump is connected to the fixed seat 17 below the second slider 242 through the air inlet hole 244, when the air pump inflates the fixed seat 17, the gas enters the fixed seat 17 through the air inlet hole 244 below the second slider 242, thereby causing the second slider 242 to rise. When the second slider 242 rises, it can drive the rack 23 and the first slider 241 to rise together. The rise of the rack 23 drives the gear 22 meshing with it to rotate, and when the gear 22 rotates, it drives the hook 18 to rotate through the rotating shaft 21. When the air pump inhales, the second slider 242 descends, thereby driving the rack 23 and the first slider 241 to descend. When the rack 23 descends, it will drive the hook 18 to rotate in the opposite direction through the gear 22 and the rotating shaft 21, thereby realizing the clamping and disengagement of the hook 18 and the slot. The translation mechanism 24 controls the up and down movement of the rack 23 through the cooperation of the first slider 241 and the second slider 242 through the air pump, and has a simple structure and precise control.
