Description

Technical Field

[0001] The utility model relates to the technical field of ammonium bicarbonate production, in particular to a crystal removal device for ammonium bicarbonate. Background Art

[0002] Ammonium bicarbonate is a white compound in the form of granular, plate-like or columnar crystals with an ammonia smell. During the production process of ammonium bicarbonate, heated ammonia water is transported to a carbonization tower through a pipeline and reacts with carbon dioxide to eventually generate ammonium bicarbonate. The product enters a cooling tower after instantaneous boiling, is cooled by cold water, and then enters a precipitator, and is then transported to a separator for further separation, and finally soda ash is obtained and transported out. After a long period of use, the sodium bicarbonate carbonization tower in the prior art is prone to accumulation of ammonium salt on the tower wall, causing blockage of the gas outlet channel, thereby reducing the space for the gas-liquid contact channel of the medium in the tower, resulting in a large pressure difference and overpressure in the carbonization system, which seriously affects production safety.

[0003] For example, a Chinese utility model patent disclosed in China with publication number CN213670682U and authorization announcement date July 13, 2021 discloses a device for removing crystals in an ammonium bicarbonate carbonization tower, comprising a carbonization tower body, a support leg fixedly installed on the top of the carbonization tower body, a feed port fixedly installed on both sides of the bottom of the carbonization tower body, a mobile motor fixedly connected to the top of the moving block, a transmission belt wrapped around the outer wall of the output shaft of the mobile motor, a rotating shaft movably connected inside the moving block, a mobile tooth fixedly connected to the outer wall of the rotating shaft, a mobile card slot provided on the outer wall of the slide rail, and a chip removal port provided at the bottom of the carbonization tower body.

[0004] However, in actual use, although the above device cleans the inner wall of the carbonization tower body through the cleaning brush on the outer wall of the cleaning rod, the device is not provided with a mechanism for cleaning the bottom of the inner wall of the carbonization tower body, so that the bottom of the carbonization tower body cannot be cleaned. In addition, the device is not provided with a flushing mechanism, so that the crystals brushed off by the cleaning brush are difficult to be discharged from the chip discharge port. Utility Model Content

[0005] The utility model aims to provide a crystal removing device for ammonium bicarbonate to solve the problem that the existing crystal removing device for ammonium bicarbonate has poor cleaning effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crystal removal device for ammonium bicarbonate, comprising a shell, a water injection pipe is rotatably connected to the center of the top of the shell, four connecting pipes are connected to the bottom of the side wall of the water injection pipe, and the four connecting pipes are commonly connected to a spray pipe, a plurality of nozzles are arranged at the bottom of the spray pipe, a rotating shaft is arranged at the bottom of the water injection pipe, a first scraper is arranged at one end of the top of the rotating shaft, and a second scraper is arranged at one end of the bottom of the rotating shaft, a motor is arranged at the top of the shell adjacent to the water injection pipe, the output end of the motor is meshed and connected with the outer wall of the water injection pipe, and a discharge port is arranged at the bottom of the shell.

[0007] Preferably, the output end of the motor is fixedly connected with a first gear, one end of the outer wall of the water injection pipe is fixedly connected with a second gear, and the first gear is meshingly connected with the second gear.

[0010] Preferably, a feed port is provided at one end of the top of the housing away from the motor.

[0011] Preferably, a valve is provided at one end of the discharge port.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model drives the water injection pipe to rotate by a motor, thereby driving the rotation shaft to rotate, and then driving the first scraper and the second scraper to rotate, so as to scrape off the crystals on the inner wall of the shell, and connect the spray pipe and the water injection pipe together through the connecting pipe. In this way, when people inject water into the water injection pipe, the water will flow into the spray pipe through the connecting pipe, and then be sprayed out from the nozzle on the spray pipe, so as to flush the inner wall of the shell, so that the crystals scraped off by the first scraper and the second scraper will flow out from the discharge port along the water flow, and through this design, when the water injection pipe rotates, the spray pipe can rotate together, thereby driving the nozzle to rotate, so that a better flushing effect can be achieved.

Since the output end of the motor 9 is aligned with the outer wall of the water injection pipe 2, the water will flow into the spray pipe 4 through the connecting pipe 3 and will be sprayed out from the nozzle 5 on the spray pipe 4. They are meshingly connected together, so when the motor 9 is turned on, it will drive the water injection pipe 2 to rotate, thereby driving the spray pipe 4 to rotate together, and then driving the nozzle 5 to rotate, so that the nozzle 5 can achieve a better flushing effect during the rotation process.

[0027] Working principle: During use, when the ammonium bicarbonate crystals on the inner wall of the housing 1 need to be removed, first prepare a water pump, align the output end of the water pump with the opening of the water injection pipe 2, and then turn on the water pump to allow it to deliver water to the water injection pipe 2. At this time, the water will flow into the spray pipe 4 through the connecting pipe 3 and will be sprayed out from the nozzle 5 on the spray pipe 4, wherein the output port of the nozzle 5 is tilted outwardly, so that the water sprayed from the nozzle 5 can rinse the inner wall of the housing 1, and then turn on the motor 9. Under the drive of the motor 9, the first gear 11 will rotate. Since the first gear 11 and the first gear 11 are connected The second gear 12 on the water injection pipe 2 is meshingly connected together, so when the first gear 11 rotates, it will drive the water injection pipe 2 to rotate, thereby driving the spray pipe 4 to rotate together, and then driving the nozzle 5 to rotate, so that the nozzle 5 can achieve a better flushing effect during the rotation process. In addition, when the water injection pipe 2 rotates, it will also drive the rotating shaft 6 to rotate, and then drive the first scraper 7 and the second scraper 8 to rotate. During the rotation of the first scraper 7 and the second scraper 8, the crystals on the inner wall of the outer shell 1 can be scraped off, and these scraped crystals will flow out from the discharge port 10 along with the water sprayed from the nozzle 5.
