The emergence of adsorption trough chute provides an effective solution to these problems. The adsorption trough chute is mainly used to transport fluid materials from one location to another, realize the directional flow of materials, and improve the material transmission efficiency in the production process. In the carbonation decomposition production of alumina sintering method, a certain amount of carbon dioxide gas is introduced into the sodium aluminate solution in the adsorption tank, that is, the method of producing aluminum hydroxide by carbonation decomposition is adopted; after the carbon dioxide gas is introduced into the adsorption tank, in order to allow the carbon dioxide and the sodium aluminate solution to fully react for a certain time, the adsorption tank is often provided with multiple adsorption tanks, and the multiple adsorption tanks are arranged with a height difference, so that the carbon dioxide and the solution can have sufficient reaction time, and the solution is transported between the various adsorption tanks through the adsorption tank chute; at the current stage, the adsorption tank chute is usually arranged outside the adsorption tank.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-7 The utility model provides a technical solution: a conveying chute device of an adsorption tank for aluminum oxide production, comprising a first tank 1, an end tank 3 and a plurality of intermediate tanks 2 arranged between the first tank 1 and the end tank 3, preferably, three intermediate tanks 2 are arranged; the first tank 1, the end tank 3 and the intermediate tank 2 together constitute the main body of the adsorption tank, providing a reaction space for the production and preparation of aluminum oxide, a feed trough 4 connected to its inner cavity is installed on the upper side of the first tank 1, and the end of the feed trough 4 away from the first tank 1 is fixed to the upper side of the first intermediate tank 2 and connected to the inner cavity of the intermediate tank 2, when in use, raw materials can be injected into the first tank 1, a feed trough 6 is fixed on the upper part of the inner cavity of the intermediate tank 2, and the feed trough 6 in the first intermediate tank 2 is correspondingly connected to the feed trough 4, the material in the first tank 1 is transported to the top of the inner cavity of the intermediate tank 2 through the feed trough 6, and then the material enters the intermediate tank 2 through the feed trough 6, so that the material flows to the next level in the adsorption tank.
[0023] A built-in chute 8 is also fixed at the upper part of the inner cavity of the middle trough 2 near the feed trough 6, and one end of the built-in chute 8 is connected to the inner cavity of the feed trough 6, and the other end of the built-in chute 8 passes through and extends to the outside of the middle trough 2. External troughs often occupy a large external space, and the built-in chute 8 used in the utility model can make full use of the space inside the middle trough 2, making the overall equipment layout more compact, reducing the equipment footprint, and facilitating installation and use in production sites with limited space. The built-in chute 8 can be better integrated with the main structure of the middle trough 2, reducing the cost of external trough road construction, and being constructed inside the middle trough 2 can save the trough wall of the built-in chute 8 close to the side of the middle trough 2 and the trough wall above the built-in chute 8, which is lower in cost. Compared with the external chute, during abnormal operation of the built-in chute 8, excess liquid overflow will only flow into the middle trough 2 and will not flow to the outside to cause unnecessary waste.
[0024] In addition, the built-in chute 8 can better utilize the temperature in the intermediate tank 2 for insulated transportation, greatly increasing the insulation effect of the transportation process, and the built-in chute 8 can be protected by the intermediate tank 2, reducing the impact of external factors on the built-in chute 8, avoiding external impacts, dust and debris intrusion, etc., thereby reducing the maintenance cost of the equipment.
[0025] The inner cavities of two adjacent intermediate troughs 2 are connected by a connecting trough 11. A transfer trough 10 is installed on the side of the material outlet side of the intermediate trough 2. One end of the transfer trough 10 is connected and fixed to one end of the built-in chute 8 that passes through the intermediate trough 2, and the other end of the transfer trough 10 is connected to the inner cavity of the connecting trough 11. The setting of the transfer trough 10 facilitates the material in the built-in chute 8 to flow to the connecting trough 11 so that the material flows to the next level. The other end of the connecting trough 11 is connected to the built-in chute 8 in the next intermediate trough 2. The intermediate trough 2 at the end is also connected to the inner cavity of the final trough 3 through the connecting trough 11, and the connecting trough 11 is located on the upper side of the final trough 3. After the material is transported from the first trough 1 to the first intermediate trough 2 through the feeding trough 4, part of the material is added to the intermediate trough 2 through the feeding trough 6, and the other part of the material is transported to the connecting trough 11 by the built-in chute 8, and flows to the next level for reaction preparation of alumina; in addition, the material in the previous level trough can also flow directly to the next level through the connecting trough 11, which is convenient for the step-by-step flow of the material in the first trough 1, the intermediate trough 2, and the final trough 3.
[0026] Preferably, the other end of the transfer tank 10 is connected to the inner cavity of the connecting tank 11 from above the connecting tank 11 , and one end of the connecting tank 11 passes through the middle tank 2 and is located inside the middle tank 2 .
[0027] The heights of the first trough 1, the middle trough 2, and the last trough 3 are gradually reduced, and the connecting trough 11 and the transfer trough 10 are all inclined. Figure 1 , Figure 3 As shown, this method facilitates the flow and transportation of materials through the chute device.

The open top of the transfer trough 10 and the open top of the connecting trough 11 are both installed with sealing covers 12 to ensure the thermal insulation effect of the transfer trough 10 and the connecting trough 11.
[0029] A first gate 5 is installed in the feed trough 4, and the first gate 5 is arranged close to the first trough 1. The first gate 5 is used to control the material in the first trough 1 to flow to the next level through the feed trough 4. A second gate 7 is installed in the feed trough 6, and a third gate 9 is installed in the built-in chute 8. The arrangement of the second gate 7 and the third gate 9 is convenient for controlling the amount of external material entering the adsorption trough. When one of the adsorption troughs fails, the second gate 7 in the adsorption trough can be closed, and the third gate 9 can be opened to allow the material in the built-in chute 8 to flow directly to the next level, which is convenient for the use of the chute device. A fourth gate 13 is installed in the connecting trough 11, and the fourth gate 13 is arranged close to the previous intermediate trough 2.

The feed pipe 15 facilitates the material in the adsorption trough to enter the connecting trough 11, so as to realize the flow of material in the chute device.
