Description

Technical Field

[0001] This utility model relates to the field of aluminum trichloride production technology, and in particular to a crystallizer for aluminum trichloride production. Background Technology

[0002] Currently, most anhydrous aluminum trichloride production enterprises use metallic aluminum as raw material. After preheating the treated high-purity aluminum, it is added to a closed chlorination reactor. Chlorine gas reacts with metallic aluminum at 800-900℃ to produce anhydrous aluminum trichloride. The generated anhydrous aluminum trichloride enters the condenser and is then manually collected to obtain the product, anhydrous aluminum trichloride. The traditional anhydrous aluminum trichloride process still uses manual tapping of the collector to discharge the material.

[0003] A search revealed that patent CN217411758U discloses a crystallizer for aluminum trichloride production. This device uses a motor to drive a cam, which strikes the inner wall of the collection chamber to cause crystals to fall. However, the continuous striking of the collection chamber by the cam during use can deform the sidewalls, affecting the device's lifespan, and cannot guarantee complete removal of crystals from the inner wall. Patent CN219149285U discloses another crystallizer for production, which uses a rotating rod to drive connecting strips and scrapers to crystallize the inner wall of a tank. However, this device requires manual rotation of the rotating rod for scraping, and wear between the scraper and the tank wall can create gaps, affecting subsequent scraping. Furthermore, severely worn scrapers are difficult to disassemble and replace. Therefore, this invention addresses these shortcomings. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crystallizer for aluminum trichloride production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crystallizer for aluminum trichloride production, comprising a collection tank, a bottom hopper fixedly connected to the bottom of the collection tank, and a discharge pipe fixedly connected to the bottom of the bottom hopper, an inlet pipe fixedly fixed to the top of the side wall of the collection tank, a motor fixedly fixed to the middle of the upper surface of the collection tank, a vertical shaft fixedly connected to the bottom output end of the motor, the vertical shaft extending through the top wall of the collection tank into the interior of the collection tank, a connecting component fixedly fixed to the bottom of the vertical shaft, and a discharge component fixedly fixed to the surface of the connecting component, the discharge component being located inside the bottom hopper and the discharge pipe, and multiple telescopic components fixedly fixed to the top side wall of the vertical shaft, each telescopic component having a detachable scraping component fixedly connected to its movable end.

[0006] Furthermore, the top wall of the collection tank is provided with an opening, and a side cover is rotatably connected to the inside of the opening via a hinge.

[0007] Furthermore, the connecting assembly includes a square rod fixed to the bottom of the vertical shaft, the discharge assembly includes a sleeve, and a spiral blade is fixed to the outer wall of the sleeve. A square groove is provided in the middle of the sleeve, and the sleeve is slidably sleeved onto the surface of the square rod through the square groove. The spiral blade is located inside the discharge pipe.

[0008] Furthermore, a screw is fixed to the bottom end of the square rod, and an internal thread cap is rotatably connected to the surface of the screw. The sleeve is located between the vertical axis and the internal thread cap, and the top of the internal thread cap is in contact with the bottom end of the sleeve.

[0009] Furthermore, the scraping assembly includes a vertical scraper that fits against the inner wall of the collection tank, and an inclined scraper is fixed at the bottom end of the vertical scraper, the inclined scraper fitting against the inner wall of the hopper.

[0010] Furthermore, a connecting sleeve is fixed to the top of the vertical scraper, and two symmetrical locking holes are opened on the side wall of the connecting sleeve. The telescopic component includes a horizontal bar fixedly connected to the vertical axis, and a sleeve is slidably sleeved on the surface of the end of the horizontal bar away from the vertical axis. The end of the sleeve away from the horizontal bar is inserted into the inside of the connecting sleeve, and a second spring is fixedly connected between the inner wall of the sleeve and the horizontal bar.

[0011] Furthermore, the sleeve has two symmetrical grooves on the side wall of one end inside the connecting sleeve.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model is a crystallizer for aluminum trichloride production, which includes a collection tank, a hopper, a discharge pipe, a motor, a vertical shaft, a connecting assembly, a discharge assembly, a scraping assembly, and a telescopic assembly. When the motor drives the vertical shaft and the discharge assembly to rotate, the telescopic assembly at the top of the vertical shaft can drive the scraping assembly to rotate, thereby scraping off the crystals on the inner wall of the collection tank and the hopper without the need for manual knocking and scraping. At the same time, the discharge assembly discharges the crystals from the discharge pipe. If the scraper of the scraping assembly is worn, the telescopic assembly will squeeze the scraper to keep it in close contact with the inner wall of the collection tank to avoid affecting the scraping.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a crystallization trap for aluminum trichloride production is disclosed, comprising a trapping tank 1, a bottom hopper 2 fixedly connected to the bottom end of the trapping tank 1, and a discharge pipe 3 fixedly connected to the bottom end of the bottom hopper 2. An inlet pipe 11 is fixedly fixed to the top of the side wall of the trapping tank 1. A motor 4 is fixedly fixed to the middle of the upper surface of the trapping tank 1. A vertical shaft 5 is fixedly connected to the bottom output end of the motor 4. The vertical shaft 5 extends through the top wall of the trapping tank 1 into the interior of the trapping tank 1. A connecting component 6 is fixedly fixed to the bottom end of the vertical shaft 5, and a discharge component 7 is fixedly fixed to the surface of the connecting component 6. The discharge component 7 is located inside the bottom hopper 2 and the discharge pipe 3. Multiple telescopic components 9 are fixedly fixed to the top side wall of the vertical shaft 5. A detachable scraping component 8 is fixedly connected to the movable end of each telescopic component 9.

[0024] The top wall of the collection tank 1 has an opening, and a side cover 10 is connected to the inside of the opening by a hinge.

[0025] The scraping assembly 8 inside the collection tank 1 can be disassembled and replaced by opening the side cover 10.

[0026] The connecting component 6 includes a square rod 61 fixed to the bottom of the vertical shaft 5. The discharge component 7 includes a sleeve 71, and a spiral blade 73 is fixed on the outer wall of the sleeve 71. A square groove 72 is provided in the middle of the sleeve 71. The sleeve 71 is slidably sleeved on the surface of the square rod 61 through the square groove 72. The spiral blade 73 is located inside the discharge pipe 3.

[0027] By engaging the square rod 61 with the square groove 72, the vertical shaft 5 can drive the sleeve 71 and the spiral blade 73 to rotate synchronously. When the spiral blade 73 rotates inside the discharge pipe 3, it can push the crystals out along the discharge pipe 3.

[0028] A screw 62 is fixed to the bottom end of the square rod 61. An internal thread cap 63 is rotatably connected to the surface of the screw 62. The sleeve 71 is located between the vertical shaft 5 and the internal thread cap 63, and the top of the internal thread cap 63 is in contact with the bottom end of the sleeve 71.

[0029] The sleeve 71 is fixed by compression between the internal thread cap 63 and the vertical shaft 5. Therefore, when disassembling the sleeve 71, first unscrew the internal thread cap 63 from the surface of the screw 62, and then pull the sleeve 71 downward from the surface of the square rod 61. This allows the sleeve 71 and the spiral blade 73 to be pulled out from the discharge pipe 3, facilitating the replacement of the sleeve 71 and the spiral blade 73 as a whole.

[0030] The scraping assembly 8 includes a vertical scraper 81 that is attached to the inner wall of the collection tank 1, and an inclined scraper 82 is fixed at the bottom end of the vertical scraper 81. The inclined scraper 82 is attached to the inner wall of the hopper 2.

[0031] The vertical scraper 81 and the inclined scraper 82 can scrape the material from the inner walls of the collection tank 1 and the bottom hopper 2, respectively.

[0032] A connecting sleeve 83 is fixed to the top of the vertical scraper 81. Two symmetrical locking holes 84 are opened on the side wall of the connecting sleeve 83. The telescopic component 9 includes a horizontal bar 91 fixedly connected to the vertical shaft 5. A sleeve 92 is slidably sleeved on the surface of the horizontal bar 91 away from the vertical shaft 5. The end of the sleeve 92 away from the horizontal bar 91 is inserted into the inside of the connecting sleeve 83. A second spring 96 is fixedly connected between the inner wall of the sleeve 92 and the horizontal bar 91.

[0033] Under the extrusion force of the second spring 96, the vertical scraper 81 and the inclined scraper 82 can always be in contact with the inner wall of the collection tank 1 and the bottom hopper 2, and the scraping assembly 8 can be driven to rotate inside the collection tank 1 by the telescopic assembly 9.

[0034] The sleeve 92 has two symmetrical grooves 93 on the side wall of one end inside the connecting sleeve 83. A first spring 94 is fixedly connected to the inner side wall of the groove 93, and a locking tooth 95 is fixedly connected to the other end of the first spring 94. The end of the locking tooth 95 away from the first spring 94 is inserted into the locking hole 84.

[0035] After the retaining teeth 95 are engaged with the retaining holes 84, the vertical scraper 81 and the sleeve 92 are fixedly connected. When it is necessary to disassemble the vertical scraper 81, first squeeze the retaining teeth 95 to disengage from the retaining holes 84, and then pull the sleeve 92 out of the connecting sleeve 83. When replacing the vertical scraper 81, similarly, first squeeze the retaining teeth 95, then press the vertical scraper 81 against the inner wall of the collection tank 1, and then insert the sleeve 92 into the connecting sleeve 83. Under the elastic force of the first spring 94, the retaining teeth 95 engage with the retaining holes 84, thus fixing the vertical scraper 81 in place.

[0036] Working principle: Raw materials enter the collecting tank 1 through the feed pipe 11. After crystallization is completed, the motor 4 is started to drive the telescopic component 9, the scraping component 8, and the discharge component 7 to rotate. The vertical scraper 81 and the inclined scraper 82 can scrape off the crystals on the inner wall of the collecting tank 1 and the inner wall of the bottom hopper 2. The crystals then slide into the discharge pipe 3, and the rotating spiral blade 73 can push the crystals out of the discharge pipe 3. If it is necessary to replace the scraping component 8, open the side cover 10, then rotate the scraping component 8 to the side cover 10, and disassemble and replace the scraping component 8 from the opening. When replacing the discharge component 7, it can be disassembled and replaced from the bottom of the discharge pipe 3.
