DRYING APPARATUS AND SYSTEM FOR PREPARING BATTERIES
The present application relates to a drying apparatus and a system for preparing batteries. The drying apparatus includes a drying tower and a cooling mechanism. The cooling mechanism is disposed on the drying tower, and the cooling mechanism is used for cooling the inner wall of the drying tower, so that the temperature of the inner wall of the drying tower is controlled within the required temperature range. In this way, when the drying tower performs spray drying operation, after the material is in contact with the inner wall of the drying tower, the phenomenon that the material melts because of a high temperature of the inner wall and adheres to the inner wall is avoided. This reduces the probability of the material hanging on the wall, thereby improves the production rate and granulation quality of the material.
1 . A drying apparatus, comprising:
a drying tower; and
a cooling mechanism, disposed on the drying tower, for cooling an inner wall of the drying tower;
wherein the cooling mechanism comprises reinforcing members and a cooling member disposed on an outer wall of the drying tower, and each reinforcing member is at least partially connected between the cooling member and the outer wall of the drying tower.
2 . The drying apparatus according to claim 1 , wherein the cooling mechanism further comprises a power source, the cooling member has a cooling channel, and the power source is used for driving a cooling medium to flow in the cooling channel.
3 . The drying apparatus according to claim 2 , wherein the cooling member is annularly disposed on the periphery of the drying tower, and the cooling channel is formed between the cooling member and the outer wall of the drying tower.
4 . The drying apparatus according to claim 3 , wherein the cooling mechanism further comprises a flow equalizer annularly disposed on the periphery of the drying tower, the inflow end of the cooling channel communicates with the flow equalizer, and the power source is used for driving the cooling medium in the flow equalizer to flow into the cooling channel.
5 . The drying apparatus according to claim 2 , wherein the reinforcing member is annularly disposed on the periphery of the drying tower, and the part of the reinforcing member located in the cooling channel is provided with a circulating port, the circulating port being used for the cooling medium of the cooling channel to circulate.
6 . The drying apparatus according to claim 1 , wherein one end of the reinforcing member away from the drying tower in the radial direction of the drying tower penetrates out of the cooling member.
7 . The drying apparatus according to claim 1 , wherein the drying tower has an air outlet, and the cooling member extends on the outer wall of the drying tower to be adjacent to the air outlet.
8 . The drying apparatus according to claim 7 , wherein the drying tower comprises a first part and a second part, the second part having the air outlet, the cross-sectional area S in the second part gradually decreases from the end of the second part close to the first part to the end of the second part having the air outlet, and the cooling member is disposed on the first part and extends to the second part.
9 . The drying apparatus according to claim 2 , wherein the cooling mechanism further comprises a discharge member disposed on the drying tower, and the discharge member has discharge ports communicating with the cooling channel.
10 . The drying apparatus according to claim 9 , wherein the number of the discharge ports is at least two, and the discharge ports are all disposed at intervals around the periphery of the drying tower.
11 . The drying apparatus according to claim 1 , wherein the drying apparatus further comprises a thermal insulation layer, and the thermal insulation layer is disposed outside the cooling member in a sleeving mode.
12 . The drying apparatus according to claim 1 , wherein the drying apparatus further comprises a heat exchanger, and the heat exchanger communicates with one end of the cooling member for the cooling medium to flow in.
13 . A system for preparing batteries, comprising the drying apparatus according to claim 1 .
