[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5In this embodiment of the present invention, a closed feeding device for mesitylene includes a feeding assembly 1 consisting of a feeding bin 101, a top cover 102, and a feeding port 103. The top cover 102 is fixed to the top of the feeding bin 101 by a flange, and the feeding port 103 is fixed to the top of the top cover 102 and communicates with the inner cavity of the feeding bin 101. A moisture-proof air pressure balance assembly 2 is provided inside and outside the feeding bin 101 and on the top of the top cover 102.

[0032] The moisture-proof air pressure balance component 2 includes an air intake unit, a wall scraping unit, and an air outlet unit;

[0033] The air intake unit is used to deliver inert gas into the feeding hopper 101 during feeding;

[0034] The wall scraping unit operates using the impact force of inert gas to scrape the inner wall of the feeding hopper 101.

[0035] The venting unit is used to vent excess inert gas inside the feeding bin 101 when feeding material into the feeding bin 101.

[0036] The exhaust unit includes an exhaust port 201 and a filter 202;

[0037] The exhaust port 201 is fixed to the top of the top cover 102 and extends through to the bottom of the top cover 102. The filter 202 is distributed inside the feeding bin 101 and is fixed to the bottom of the exhaust port 201 through a flange structure. The top of the exhaust port 201 is connected to the external pipeline through a pressure relief valve.

[0038] The exhaust port 201 is used to discharge the inert gas inside the feeding bin 101 to the outside, and the filter 202 is used to filter the output inert gas.

[0039] The intake unit includes a transmission box 203, a mounting bracket 204, an intake pipe 209, an exhaust pipe 210, a connecting pipe 211, and a one-way valve 212;

[0040] The transmission box 203 is fixedly installed inside the feeding bin 101 near the bottom by the fixing frame 204. The air inlet pipe 209 and the air outlet pipe 210 pass through the feeding bin 101 from the outside and are connected and fixed to the transmission box 203. The air inlet pipe 209 and the air outlet pipe 210 are in communication with the inner cavity of the transmission box 203.

[0041] The connecting pipe 211 is distributed outside the feeding bin 101, and one end of the connecting pipe 211 is fixedly connected to the air outlet pipe 210 through a flange structure. The other end of the connecting pipe 211 extends to the inside of the feeding bin 101 and is fixedly connected to the one-way valve 212. The one-way valve 212 penetrates from the bottom of the filter 202 into the inner cavity of the filter 202.

[0042] The channel consisting of the inlet pipe 209, the inner cavity of the transmission box 203, the outlet pipe 210, the connecting pipe 211, and the one-way valve 212 is used to deliver inert gas into the feeding bin 101, and at the same time realize the backflushing operation of the filter 202.

[0043] The wall scraping unit includes a rotating shaft 205, a scraper 206, a wind turbine blade 207, and a reduction gear set 208;

[0044] The rotating shaft 205 is rotatably connected to the top of the fixed frame 204. The scraper 206 is symmetrically fixed to the outside of the rotating shaft 205 and fits against the bottom inner wall side of the feeding bin 101. The scraper 206 is used to scrape the bottom inner wall of the feeding bin 101 by rotating in a circle.

[0045] The wind turbine blade 207 is rotatably connected to the inner cavity of the transmission box 203. The bottom of the scraper 206 extends through the inner cavity of the transmission box 203. The output shaft of the wind turbine blade 207 is connected to the rotating shaft 205 through a reduction gear set 208. The rotation of the wind turbine blade 207 is used to realize the low-speed rotation of the rotating shaft 205.

[0046] In this embodiment, it should be noted that the bottom of the feeding hopper 101 is open and is connected to the unloading valve and screw conveyor through a flange structure to realize the controllable solid material conveying. The inlet 103 is connected to the valve and material conveying pipeline through a flange structure to realize the feeding operation of the feeding hopper 101.

[0047] When adding mesitylene into the feeding hopper 101, the inert gas (such as nitrogen or argon) inside the feeding hopper 101 is filtered through the filter 202 and discharged from the exhaust port 201. In this way, while maintaining the pressure balance inside the feeding hopper 101, oxygen and moisture can be effectively isolated, and the raw materials inside the feeding hopper 101 can be prevented from clumping or deteriorating. (It should be noted that the maximum height of the material inside the feeding hopper 101 is lower than the bottom horizontal height of the filter 202).

[0048] When the discharge valve at the bottom of the feeding hopper 101 is opened for feeding, the connection between the air inlet pipe 209 and the external pipeline is simultaneously connected (it should be noted that the air inlet pipe 209 of the exhaust port 201 is connected to the circulation pipeline of the inert gas). The inert gas is then transported to the transmission box 203 through the air inlet pipe 209 and blows the impeller blades 207. After that, it is output to the inside of the connecting pipe 211 through the air outlet pipe 210, and finally transported to the inside of the filter 202 through the one-way valve 212. At this time, some of the inert gas can pass through the filter element of the filter 202 and enter the inside of the feeding hopper 101, thereby maintaining the internal air pressure balance of the feeding hopper 101. At the same time, the filter 202 is back-blown, so that the raw materials adhering to the filter 202 are blown off. In this way, the filter 202 maintains a long-term high-efficiency filtration effect. The other part of the inert gas can be directly connected to the exhaust pipe 201 for discharge.

[0049] Meanwhile, the impeller blades 207 are driven to rotate by inert gas. The rotating impeller blades 207 drive the shaft 205 to rotate at low speed through the reduction gear set 208. The shaft 205 drives the scraper 206 to run in a circle. The scraper 206 scrapes the inner wall of the bottom of the feeding bin 101. This can effectively prevent the raw materials from adhering to the inner wall of the bottom of the feeding bin 101 and causing blockage, thus ensuring smooth and stable feeding.

[0050] Please refer to this carefully. Figures 3-4 The transmission box 203 is equipped with an air chamber and a transmission chamber. The scraper 206 is distributed inside the air chamber, and the air inlet pipe 209 and the air outlet pipe 210 are connected to the air chamber.

[0051] The bottom end of the rotating shaft 205 and the output shafts of the reduction gear set 208 and the wind turbine blades 207 are located inside the transmission compartment.

[0052] In this embodiment: the connection of the inert gas pipeline is ensured by setting up the gas chamber and the transmission chamber, and at the same time, a good rotation environment is provided for the wind turbine blades 207.

[0053] It should also be noted that the reduction gear set 208 can be a planetary reduction gear set. This structure is commonly used in existing mechanical transmissions, so it will not be described in detail here.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
