DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0026] like Figures 1-9 As shown, the utility model provides a methyl methacrylate polymerization inhibitor adding structure, which includes a material storage component 1, a metering pump 3 and a material discharge component 4.

[0027] A metering pump 3 is installed on the side of the storage assembly 1. The feed port of metering pump 3 is connected to the storage assembly 1 via a conduit 1 30. The storage assembly 1 includes an inner barrel 10. A charging pipe 11 is installed on the top of the inner barrel 10. The charging pipe 11 is equipped with a sealing cap 13 to ensure sealing during the feeding process. A discharge valve pipe 12 is installed at the bottom of the inner barrel 10, which is connected to the conduit 1 30. It is worth mentioning that an outer barrel 16 is also installed on the outside of the inner barrel 10. A vacuum chamber 17 is formed between the inner barrel 10 and the outer barrel 16. This design helps to maintain the temperature of the material in the inner barrel 10.

[0028] The discharge port of the metering pump 3 is connected to the discharge component 4 through the second conduit 31. The discharge component 4 includes a buffer shell 40. A first feed port 41 is provided on one side of the buffer shell 40. The other end of the second conduit 31 is accurately set on the first feed port 41. A temperature guide tube 42 is provided at the bottom of the buffer shell 40. A spiral discharge trough 43 is provided in the temperature guide tube 42. In order to better control the temperature, a jacketed heat exchanger 45 is provided at the bottom of the buffer shell 40, and the jacketed heat exchanger 45 is sleeved on the outside of the temperature guide tube 42. Limiting slots 44 are provided on several inner walls of the buffer shell 40 for installing a detachable filter shell 46. Several plug blocks 47 are provided on the outer wall of the filter shell 46. The plug blocks 47 are inserted in the limiting slots 44 to achieve stable installation of the filter shell 46. A second feed inlet 48 is provided on the side wall of the filter housing 46 at a position corresponding to the first feed inlet 41. A guide plate 49 is provided on one inner wall of the filter housing 46. The guide plate 49 is located below the second feed inlet 48 to help guide the flow of materials.

[0029] The top of the buffer shell 40 is provided with several magnetic blocks 410. The top of the buffer shell 40 is connected to the iron plate cover 411 through magnetism. The top of the iron plate cover 411 is provided with a handle 412 for easy operation.

[0030] A mounting plate 15 is provided on one side of the outer tub 16, on which the water level sensor 2 is mounted. The probe of the water level sensor 2 is located on the inner wall of the inner tub 10. To ensure a tight seal, the probe is covered with a sealing sleeve 21, which is located within the wall of the inner tub 10. A sealing ring 20 is installed on the connecting line of the water level sensor 2, which is located within the wall of the outer tub 16, thus ensuring the tightness and stability of the entire device.

[0031] Before use, the feed port of the mixing reaction device is accurately placed below the temperature conducting pipe 42. Next, the methyl methacrylate polymerization inhibitor is loaded into the inner barrel 10 through the charging pipe 11. Then, the jacketed heat exchanger 45 is started to heat according to the preset temperature.

[0032] When adding material, the discharge valve 12 is first opened. The metering pump 3 is then adjusted to pump out a set amount of methyl methacrylate polymerization inhibitor. The inhibitor then flows into the buffer housing 40 via the second conduit 31. As the inhibitor flows into the buffer housing 40, it passes through the filter housing 46, where impurities are filtered out. The inhibitor then flows into the spiral discharge chute 43 of the thermal conduit 42. During its flow within the spiral discharge chute 43, due to its increased travel distance, it is fully affected by the temperature of the thermal conduit 42, allowing the inhibitor to reach a suitable temperature before being added to the mixing reaction equipment for mixing.

[0033] When the filter housing 46 needs to be cleaned, the handle 412 is simply pulled, and the iron plate cover 411 is pulled out of the filter housing 46 under the action of the magnetic block 410 for cleaning.

[0034] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
