Description

Technical Field

[0001] This utility model relates to the field of calcium oxide production technology, and in particular to a cooling device for calcium oxide. Background Technology

[0002] Calcium oxide is widely used in the manufacture of calcium carbide, soda ash, bleaching powder, refractory materials, and calcium fertilizer; as a desiccant and soil conditioner; as an analytical reagent and a flux in the manufacture of fluorescent powders; in leather making and wastewater purification; as a building material and a metallurgical flux; and is the main raw material for the production of calcium hydroxide and various calcium compounds. Traditional calcium oxide production methods mainly use limestone as raw material, and the calcination process adopts a vertical kiln, where limestone is mixed with solid fuel or layered and loaded into the kiln for calcination, and the remainder is the calcium oxide product.

[0003] In the prior art, Chinese Patent Publication No. CN210374654U discloses a cooling device for calcium oxide, which includes a furnace body with a feed inlet at the upper end and a discharge outlet at the lower end. A cooling box is connected to the lower end of the discharge outlet. A cold water tank is located on one side of the cooling box, and a cooling chamber is located at the upper end of the cooling box, connected to the cold water tank. At least four cooling baffles, which are hollow plates, are fixedly connected to the inner wall of the cooling box and communicate with the cooling chamber. In this invention, cooling water from the cold water tank enters the cooling chamber, and cooling water from the cooling chamber enters the cooling baffles. The cooling baffles cool the calcium oxide in the cooling box. The cooling baffles on the four side walls of the cooling box cool the calcium oxide during the feeding process, allowing for rapid cooling. Rapidly cooled calcium oxide prevents overheating, thus maintaining its stable properties and ensuring its quality.

[0004] However, in actual use, the cooling box of this utility model is relatively closed. When calcium oxide enters, during air cooling, most of the hot air remains inside the cooling box after the cold air enters, which makes it difficult for the heat to dissipate outward and the heat dissipation efficiency is slow. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for calcium oxide, which improves the cooling effect of calcium oxide and facilitates the dissipation of heat.

[0018] A further feature of this invention is that the output end of the second water pump is fixedly connected to a second water supply pipe, which passes through the cooling tank and extends into the interior of the first water tank.

[0019] By adopting the above technical solution, the second water pipe transports water back to the first water tank, and the top of the water tank is open.

[0020] A further feature of this invention is that the support plate has a perforation inside, and the heat exchange box passes through the inside of the perforation.

[0021] By adopting the above technical solution, the heat dissipation conveyor belt contacts the surface of the heat exchange box for cooling during transport.

[0022] A further feature of this invention is that a feed inlet is provided at one end of the cooling box, and an inclined groove is fixedly connected to the inner wall of the feed inlet.
