Description

Technical Field

[0001] This utility model relates to the field of anhydrous aluminum trichloride technology, and in particular to a batch feeding device that avoids the generation of large amounts of hydrogen chloride gas. Background Technology

[0002] In actual production, anhydrous aluminum trichloride will deliquesce with moisture in the air during the feeding process, thereby producing a large amount of hydrogen chloride gas. Hydrogen chloride is corrosive and will not only corrode the equipment unit, but also strongly irritate the eyes and respiratory mucous membranes, thus affecting human health.

[0003] A search revealed a public disclosure (announcement) number: CN217101361U, which discloses a batch feeding device for anhydrous aluminum trichloride solid, belonging to the field of fine chemical technology. The device includes a housing with an inlet. A guide rod and a pressure sensor are fixedly connected to the inner wall of the housing. A storage tank is slidably connected to the guide rod, and a spring connects the storage tank to the guide rod. A partition plate is fixedly connected to the storage tank, and a discharge port is provided on the partition plate. A sealing plate is rotatably connected inside the partition plate, and a discharge port corresponding to the discharge port is provided on the sealing plate. A motor is fixedly connected to the bottom of the sealing plate. This invention achieves precise batch feeding by using the storage tank, pressure sensor, controller, motor, partition plate, and sealing plate, avoiding the generation of large amounts of hydrogen chloride gas from adding too much anhydrous aluminum trichloride solid at once.

[0004] While the above solution achieves precise batch feeding and avoids generating a large amount of hydrogen chloride gas from adding too much anhydrous aluminum trichloride solid at once, some incompletely crushed large particles of anhydrous aluminum trichloride can easily clog the material outlet on the partition, resulting in an unsmooth feeding process. Therefore, we propose a batch feeding device to avoid generating a large amount of hydrogen chloride gas. Utility Model Content

[0005] The main purpose of this utility model is to provide a batch feeding device that avoids the generation of large amounts of hydrogen chloride gas. By setting up a filtration unit and a feeding unit, it solves the problem that some incompletely crushed large anhydrous aluminum trichloride particles can easily clog the material outlet on the partition, resulting in an unsmooth feeding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A batch feeding device for avoiding the generation of large amounts of hydrogen chloride gas includes a main unit, a filter unit and a feeding unit disposed inside the main unit, a crushing unit disposed above the main unit, and a metering unit disposed inside the crushing unit.

[0008] The filter unit includes a filter element movably disposed inside the main unit, a support seat installed at the bottom of the filter element, a rotating shaft movably disposed below the filter element, a cam installed on the side wall of the rotating shaft, and a first drive motor installed at the input end of the rotating shaft.

[0009] The feeding unit includes a first feeding plate installed on the inner side wall of the main unit, a receiving groove opened on the inner side wall of the main unit, a hydraulic telescopic cylinder installed on the side wall of the receiving groove, and a second feeding plate installed on the telescopic end of the hydraulic telescopic cylinder.

[0010] Preferably, the main unit includes a box body, support feet installed at the bottom of the box body, and a discharge component disposed at the bottom of the box body.

[0011] Preferably, the discharge component includes a discharge pipe located at the bottom of the housing and a regulating valve movably installed inside the discharge pipe.

[0012] Preferably, the filter element includes a mounting base installed on the inner side wall of the housing, a connecting spring installed on the top of the mounting base, and a filter plate installed at the end of the connecting spring.

[0013] Preferably, the crushing unit includes a feeding hopper installed on the top of the housing, a crushing roller movably disposed in the feeding hopper, a second drive motor installed at the input end of one of the crushing rollers, and a transmission gear installed at the output end of the crushing roller.

[0014] Preferably, the metering unit includes a feeding roller movably installed inside the feeding hopper and located below the crushing roller, a third drive motor installed at the input end of the feeding roller, a storage trough opened on the side wall of the feeding roller, and a material collection plate installed on the inner wall of the feeding hopper and located between the crushing roller and the feeding roller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, through the configured filtration and feeding units, when anhydrous aluminum trichloride solid needs to be added in batches, after the anhydrous aluminum trichloride solid is placed into the feeding hopper, the second drive motor drives one of the crushing rollers to rotate, and through the transmission gear, drives the other crushing roller to rotate synchronously, thereby crushing the anhydrous aluminum trichloride solid and sending it into the storage tank on the side wall of the feeding roller. At this time, the third drive motor can drive the feeding roller to rotate one-quarter revolution each time, quantitatively adding anhydrous aluminum trichloride powder from one storage tank. When the anhydrous aluminum trichloride powder falls from the feeding hopper onto the filter plate, the filter plate can filter the anhydrous aluminum trichloride powder. During the filtration process, when the first drive motor drives the rotating shaft to rotate, the cam can vibrate the filter element up and down, thereby shaking off the large, incompletely crushed anhydrous aluminum trichloride particles located in the filter holes of the filter plate, avoiding blockage and ensuring a smooth feeding process.

There are two collection plates 502, which are stacked about the intersection of the two crushing rollers 402, so that the crushed anhydrous aluminum trichloride is added into the storage trough on the side wall of the feeding roller 501.

[0036] When anhydrous aluminum trichloride solid needs to be added in batches, after the anhydrous aluminum trichloride solid is placed into the feeding hopper 401, the second drive motor 403 drives one of the crushing rollers 402 to rotate, and drives the other crushing roller 402 to rotate synchronously through the transmission gear 404, thereby crushing the anhydrous aluminum trichloride solid and entering the storage tank on the side wall of the feeding roller 501. At this time, the third drive motor 503 can drive the feeding roller 501 to rotate one-quarter turn each time, so that the anhydrous aluminum trichloride powder in one storage tank is quantitatively added.

There are two collection plates 502, which are stacked about the intersection of the two crushing rollers 402, so that the crushed anhydrous aluminum trichloride is added into the storage trough on the side wall of the feeding roller 501.

[0044] When anhydrous aluminum trichloride powder falls from the feed hopper 401 onto the filter plate 2013, the filter plate 2013 can filter the anhydrous aluminum trichloride powder. During the filtration process, when the first drive motor 205 drives the rotating shaft 203 to rotate, the cam 204 can vibrate the filter element 201 up and down, thereby shaking off the large, incompletely broken anhydrous aluminum trichloride particles located in the filter holes of the filter plate 2013, avoiding blockage and ensuring a smooth feeding process.
