Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a rapid alkali discharge device for carbonization towers. Background Technology

[0002] The soda ash carbonation tower is a key piece of equipment in the soda ash production process. It introduces ammonia brine and carbon dioxide gas into the tower for reaction, followed by cooling, to generate sodium bicarbonate crystals in the reaction solution. These crystals are then discharged through the discharge port to proceed to subsequent filtration and washing processes, achieving the separation of sodium bicarbonate from the mother liquor. However, traditional soda ash carbonation towers typically discharge using only one set of discharge valves, which reduces the discharge rate. To address this, technological innovations are implemented based on existing soda ash discharge equipment from the carbonation tower. Utility Model Content

[0003] The purpose of this invention is to provide a rapid alkali discharge device for carbonation towers to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid alkali discharge device for a carbonization tower, comprising:

[0005] A soda ash carbonization tower has discharge ports evenly distributed on its outer wall. These discharge ports are connected to the reaction tank inside the tower. A connecting pipe is evenly distributed on the outer wall of the tower, and this connecting pipe is connected to the discharge port. The outlet of the connecting pipe is connected to a discharge pipe. A chute is formed through the bottom of the discharge port. A sealing plate is installed inside the discharge port and the chute. A sealing sleeve is fixedly fitted onto the outer wall of the sealing plate. A connecting plate is installed at the bottom of the sealing plate, and a hydraulic rod is installed at the bottom of the connecting plate.

[0006] Preferably, the outer wall of the sealing jacket fits into the inner wall of the discharge port and the chute, and the connecting plate is located at the bottom of the soda ash carbonation tower.

[0007] Preferably, the bottom of the hydraulic rod is provided with a base, and the top of the base is uniformly provided with first support columns.

[0008] Preferably, the first support columns are arranged in a circular array evenly on the outer wall of the soda ash carbonation tower, and the diameter of the connecting plate is the same as the bottom diameter of the soda ash carbonation tower.

[0009] Preferably, the top of the connecting plate is attached to the bottom of the soda ash carbonation tower, and the outer wall of the connecting plate is attached to the side of the first support column near the connecting plate.

[0010] Preferably, the top of the base is uniformly provided with second support columns, and the second support columns are uniformly provided at the bottom of the discharge pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention supports the soda ash carbonation tower with a first support column and limits the outer wall of the connecting plate, thereby assisting the connecting plate to move up and down stably and ensuring the stability of the device. When the reaction tank in the soda ash carbonation tower needs to be discharged, the connecting plate is moved downward by the hydraulic rod, thereby moving the sealing plate and sealing jacket downward out of the discharge port. At this time, the alkali liquid in the reaction tank will flow into the discharge pipe quickly through multiple sets of connecting pipes and be discharged through the discharge pipe, thereby achieving a rapid discharge effect.

[0017] 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.

[0018] Please see Figs. 1-3The carbonation tower alkali discharge rapid discharge equipment includes a soda ash carbonation tower 1. Discharge ports are evenly distributed on the outer wall of the soda ash carbonation tower 1, and these ports are connected to the reaction tank inside the tower. Connecting pipes 16 are evenly fixedly installed on the outer wall of the tower, and these pipes are connected to the discharge ports. A discharge pipe 11 is connected to the outlet of the connecting pipe 16. A chute is formed through the bottom of the discharge port. A sealing plate 17 is slidably installed within the discharge port and the chute. A sealing jacket 18 is fixedly fitted onto the outer wall of the sealing plate 17. The outer jacket 18 is made of polytetrafluoroethylene, which has good resistance to acid and alkali corrosion and wear. A connecting plate 19 is fixedly installed at the bottom of the sealing plate 17, and a hydraulic rod 15 is fixedly installed at the bottom of the connecting plate 19. The sealing outer jacket 18 seals the connection gap between the sealing plate 17 and the discharge port and chute, thereby improving the cooperation between the sealing plate 17 and the sealing outer jacket 18 in closing the discharge port. When the reaction tank in the soda ash carbonization tower 1 needs to discharge material, the hydraulic rod 15 drives the connecting plate 19 downwards. The connecting plate 19 moves the sealing plate 17 and the sealing jacket 18 downwards out of the discharge port. At this time, the alkaline solution in the reaction tank will flow rapidly into the discharge pipe 11 through multiple sets of connecting pipes 16 and be discharged through the discharge pipe 11. A base 12 is fixedly installed at the bottom of the hydraulic rod 15, and first support columns 13 are uniformly fixedly installed at the top of the base 12. The first support columns 13 are uniformly fixedly installed in a ring array on the outer side wall of the soda ash carbonization tower 1. The diameter of the connecting plate 19 is the same as the bottom diameter of the soda ash carbonization tower 1. The top of the connecting plate 19 is attached to the bottom of the soda ash carbonation tower 1. The outer wall of the connecting plate 19 is attached to the side of the first support column 13 near the connecting plate 19. The first support column 13 supports the soda ash carbonation tower 1 and limits the outer wall of the connecting plate 19, thereby assisting the connecting plate 19 to move up and down stably. The top of the base 12 is uniformly fixed with second support columns 14. The second support columns 14 are uniformly fixed at the bottom of the discharge pipe 11, and the discharge pipe 11 is supported by the second support columns 14.

[0019] Working principle: The first support column 13 supports the soda ash carbonization tower 1 and limits the outer wall of the connecting plate 19, thereby assisting the connecting plate 19 to move up and down stably. The second support column 14 supports the discharge pipe 11. The sealing jacket 18 seals the connection gap between the sealing plate 17 and the discharge port and the chute, thereby improving the cooperation between the sealing plate 17 and the sealing jacket 18 to close the discharge port. When the reaction tank in the soda ash carbonization tower 1 needs to be discharged, the hydraulic rod 15 drives the connecting plate 19 to move downward. The connecting plate 19 drives the sealing plate 17 and the sealing jacket 18 to move downward out of the discharge port. At this time, the alkali liquid in the reaction tank will flow into the discharge pipe 11 quickly through multiple sets of connecting pipes 16 and be discharged through the discharge pipe 11.
