Description

Technical Field

[0001] The utility model relates to a horizontal continuous cooler for anode paste. Background Art

[0002] Carbon paste made of petroleum coke and asphalt coke as aggregate and coal tar as binder. It is used as anode material for continuous self-baking aluminum electrolytic cells. Because of its high binder content (over 24%), it is in a paste state before being sintered on the upper part of the electrolytic cell, so it is called anode paste.

[0003] Currently in the industry, the continuous high-power cooler for anode paste is vertical, mainly through cold water spraying, with a temperature reduction range of 30-50 degrees Celsius. The anode paste is 200°C and the maximum temperature reduction is 150°C. Therefore, the adjustability of the temperature reduction range is limited and the cooling effect is not good. Utility Model Content

[0004] The utility model aims to overcome the existing defects and provide a horizontal continuous cooler for anode paste, which can greatly reduce the temperature of the anode paste and improve the cooling effect.

[0005] The technical solution to achieve the above-mentioned purpose is: a horizontal continuous cooler for anode paste, comprising a mounting bracket, a hollow box body is provided on the mounting bracket, a first hollow cavity is opened inside the hollow box body, a plurality of arc grooves are evenly opened on the bottom of the hollow box body, a plurality of stirring shafts are rotatably connected in the hollow box body, each stirring shaft is located in the corresponding arc groove, each stirring shaft is provided with a spiral blade, a second hollow cavity and a third hollow cavity are respectively opened inside the stirring shaft and the spiral blade, the second hollow cavity and the third hollow cavity are connected to each other, a plurality of rotary joints are connected on both sides of each stirring shaft, each stirring shaft is connected to the output end of a planetary reducer, each rotary joint is connected to a first refrigeration component, and the first hollow cavity is connected to a second refrigeration component.

[0006] Preferably, the first refrigeration component includes a plurality of first pipes, a plurality of second pipes and a first circulating thermal oil refrigerator, each of the rotary joints located at one end of the stirring shaft is connected to a corresponding first pipe, and each of the rotary joints located at the other end of the stirring shaft is connected to a corresponding second pipe, a plurality of the first pipes are connected to an output end of the first circulating thermal oil refrigerator, and a plurality of the second pipes are connected to an input end of the first circulating thermal oil refrigerator.

[0007] Preferably, the second refrigeration component includes a third pipe, a fourth pipe and a second circulating thermal oil refrigerator, the hollow box is respectively connected to the third pipe and the fourth pipe, the third pipe and the fourth pipe are respectively connected to the starting end and the end of the first hollow cavity, the third pipe is connected to the output end of the second circulating thermal oil refrigerator, and the fourth pipe is connected to the input end of the second circulating thermal oil refrigerator.

[0008] Preferably, each of the spiral blades is threadedly connected with a plurality of corresponding paddles.

[0009] Preferably, the input end of each planetary reducer is connected to a rotating shaft, the other end of each rotating shaft is connected to a gear box, the gear box is connected to the output end of the drive motor, and the gear box and the drive motor are both mounted on the mounting bracket.

[0010] Preferably, a feed inlet and a discharge outlet are respectively provided at the front and rear ends of the hollow box body.

[0011] Preferably, a temperature sensor is provided at the discharge port.

[0012] Preferably, the angle between the hollow box and the ground is 10°.

[0013] The beneficial effect of the utility model is that the anode paste contacts the outer surface of the spiral blades, the stirring shaft and the hollow box body. Since a refrigerant medium flows inside the spiral blades, the stirring shaft and the hollow box body, the anode paste will exchange heat with the outer surface of the spiral blades, the stirring shaft and the hollow box body, thereby achieving a refrigeration effect. The anode paste can contact a large heat transfer area per unit effective volume. In this indirect conduction heating method, no air is carried away to take away heat. The heat is used to heat the material. The only heat loss is the heat dissipation to the environment through the thermal insulation layer of the device body. In this way, the temperature of the anode paste can be greatly reduced, thereby improving the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
