Description

Technical Field

[0001] This utility model relates to the field of distillation and purification technology of chloroethane, specifically a filtration device for distillation and purification of chloroethane. Background Technology

[0002] Ethyl chloride, also known as ethyl chloride, is an organic compound with the chemical formula C₂H₅Cl. It is a colorless gas at room temperature and pressure, with an ether-like odor. It is slightly soluble in water and miscible with most organic solvents. It is mainly used as a raw material for tetramethyllead, ethyl cellulose, etc., and can also be used as a refrigerant, anesthetic, bacterium, smoke agent, ethylating agent, etc. Furthermore, it can be used as a catalyst for polypropylene and as a solvent for phosphorus, sulfur, oils, resins, waxes, etc. A chloroethane distillation column is a device used to separate mixtures of chloroethane. Before distillation purification, the liquid chloroethane mixture can be pretreated by filtration.

[0003] In response, Chinese utility model patent CN222454614U discloses a distillation and purification device for NMP waste liquid recovery, belonging to the field of waste liquid treatment technology. The device includes a purification tower, a transfer pump fixedly connected to one side of the purification tower, a fixed tank fixedly connected to one end of the transfer pump, a sealing cover centrally located on the top surface of the fixed tank, a connecting pipe fixedly connected to one side of the top surface of the sealing cover, a liquid delivery pipe fixedly connected to the upper end of the connecting pipe, and a filter cylinder located on the side of the bottom surface of the sealing cover. The filter cylinder contains a cleaning mechanism. This design uses a filter assembly to effectively filter the waste liquid, and the filter assembly is easy to remove, facilitating the centralized cleaning of filtered impurities. Furthermore, a cleaning component is included to clean impurities from the inner surface of the filter element, reducing filter clogging and ensuring smooth recovery operations.

[0004] When in use, this distillation and purification device filters the liquid through a filter cylinder. The sealing cap is connected to the top of the fixed barrel by a threaded connection, which facilitates the separation of the sealing cap from the fixed barrel. However, the operator needs to rotate the entire sealing cap, as well as the filter cylinder and the stirring mechanism, back and forth significantly. The process of separating the sealing cap is quite laborious.

[0005] Therefore, we propose a filtration device for the distillation and purification of chloroethane to solve the above problems. Utility Model Content

A rubber gasket 8 is fixedly provided on the bottom surface of the sealing cover 7, and the bottom surface of the rubber gasket 8 contacts the bottom surface of the groove 6. A threaded groove 71 is formed on the bottom surface of the sealing cover 7. A mounting ring 10 is fixedly connected to the top surface of the filter cylinder 9, and the threaded groove 71 is threaded at the external thread of the mounting ring 10. After the sealing cover 7 is removed, the mounting ring 10 can be unscrewed from the threaded groove 71 at the bottom of the sealing cover 7 by rotating the filter cylinder 9, so that the filter cylinder 9 can be disassembled for cleaning. Connecting blocks 15 are fixedly connected to both ends of the top surface of the sealing cover 7. A sliding groove 151 is provided inside the block 15. One end of a spring 16 is fixedly connected to one side of the sliding groove 151, and the other end of the spring 16 is fixedly connected to one side of the slider 17. A limiting block 18 is fixedly connected to the other side of the slider 17. The slider 17 is slidably connected to the sliding groove 151. A toggle block 19 is fixedly connected to the top surface of the slider 17. Fixed blocks 14 are fixedly connected to both ends of the top surface of the fixed barrel 1. Limiting slots 141 are provided on the sides of the two fixed blocks 14 that are close to each other. The limiting block 18 engages with the limiting slots 141. A handle 20 is fixedly connected to the top surface of the connecting block 15. The handle 20 is provided to facilitate the disassembly and assembly of the sealing cover 7.

[0024] Example 2:

[0025] Please see Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The liquid inlet pipe 13 is fixedly installed inside the top of the sealing cover 7. The liquid inlet pipe 13 can be connected to other pipes. The liquid inlet pipe 13 and the filter cylinder 9 are internally connected.

[0026] Positioning blocks 11 are fixed to both ends of the top surface of the sealing cover 7, and limiting frames 12 are fixed to both ends of the top surface of the fixing bucket 1. The positioning blocks 11 are snapped into the limiting frames 12, which can be used for positioning and limiting when installing the sealing cover 7, making the installation of the sealing cover 7 convenient.

[0027] A toggle opening 152 is provided on the inner top surface of the slide groove 151. The toggle block 19 is slidably connected to the toggle opening 152, which can limit the range of movement of the toggle block 19.

[0028] Limiting blocks 171 are fixedly connected to both sides of the slider 17. Limiting grooves 1511 are opened on both sides of the slide groove 151. The limiting blocks 171 are slidably connected to the limiting grooves 1511, which can limit the range of movement of the slider 17 and improve the stability of the movement of the slider 17.

[0029] The limiting block 18 can slide within the connecting block 15 via the slider 17.

[0030] Example 3:

[0031] Please see Figure 1-3This is the third embodiment of the present invention. This embodiment is based on the above two embodiments. In actual use, the liquid mixture containing chloroethane enters the fixed tank 1 through the inlet pipe 13. After being filtered by the filter cylinder 9, the filtered liquid mixture is transported to the purification tower 5 through the delivery pump 2 and connecting pipe 3 via the delivery pipe 4 for purification and distillation. When it is necessary to disassemble the sealing cap 7, one person can operate it. The worker holds the handle 20 with both hands. Since the handle 20 is close to the actuating block 19, one finger is pulled out from each hand to actuate the actuating block 19 to move the slider 17 and the limiting block 18. This causes the slider 17 to compress the spring 16, causing the limiting blocks 18 at both ends to disengage from the limiting slot 141, thus releasing the limitation on the sealing cap 7. Then, by lifting the handle 20, the sealing cap 7 can be pulled up for disassembly. This makes it easier to disassemble and reassemble the sealing cap 7, and the operation is more labor-saving than twisting the sealing cap 7.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
