Description

Technical Field

[0001] The utility model relates to the technical field of sodium sulfide processing equipment, in particular to sodium sulfide cooling and drying equipment. Background Art

[0002] Sodium sulfide, also known as stinky alkali, stinky soda, and alkali sulfide, is an inorganic compound with a chemical formula of Na2S. It is a colorless crystalline powder, easily soluble in water, insoluble in ether, and slightly soluble in ethanol. It can cause burns when it comes into contact with the skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to the air, sodium sulfide will emit toxic hydrogen sulfide gas with the smell of rotten eggs. Industrial sodium sulfide contains impurities and its color is pink, brownish red, and khaki.

[0003] When processing sodium sulfide, a cooling device is needed to cool and dry the product. The existing cooling device only has one cooling process, resulting in poor cooling effect on the product and failure to quickly cool the product, which not only affects production efficiency but also affects product quality, and is not conducive to promotion and use.

[0004] Therefore, how to provide a sodium sulfide cooling and drying equipment with good cooling effect has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide a sodium sulfide cooling and drying device with good cooling effect.

[0006] To achieve the above-mentioned purpose, the utility model provides a sodium sulfide cooling and drying device, including: a cold rotary kiln, on which a logistics channel for sodium sulfide to enter and exit is preset, and also includes a cooling mechanism, which includes an air cooling component and a liquid cooling component to form a double cooling process.

[0007] The sodium sulfide products to be cooled and dried and those that have been cooled and dried enter and exit the cold rotary kiln through the corresponding material channel. This method is common knowledge known in the art and will not be described in detail. The cooling mechanism is used to cool the sodium sulfide product. The design of the air cooling component and the liquid cooling component forms a double cooling process for the sodium sulfide product, thereby achieving the purpose of rapidly cooling the sodium sulfide product.

[0008] Preferably, the specification of the cold rotary kiln is φ900*180000mm and the material is stainless steel.

[0009] The cold rotary kiln adopts the existing structure on the market, and is connected to an external driving device (not shown in the figure) when actually used. This method is common knowledge in the field, so it will not be repeated.

[0010] Preferably, the logistics channel comprises a sodium sulfide feed port and a sodium sulfide discharge port, the sodium sulfide feed port is preset at one end of the cold rotary kiln, and the sodium sulfide discharge port is preset at the other end of the cold rotary kiln.

[0011] The sodium sulfide product to be processed enters the cold rotary kiln through the sodium sulfide feed port, and the processed sodium sulfide product is discharged to the outside through the sodium sulfide discharge port for the next process.

[0012] Preferably, the sodium sulfide feed port and the sodium sulfide discharge port are arranged in an inclined shape.

[0013] The inclined design prevents the sodium sulfide product from remaining in the sodium sulfide feed port and the sodium sulfide discharge port, thereby preventing blockage, and further demonstrating the practicability of the device.

[0014] Preferably, the air-cooling component is an air-conditioning air inlet, and the air-conditioning air inlet is arranged at the sodium sulfide feed inlet.

[0015] The other end of the air inlet of the air conditioner is connected to the external air conditioning cooling system, so that the refrigerant generated when the air conditioning cooling system is working is blown to the sodium sulfide product at the sodium sulfide feed inlet through the air inlet of the air conditioner, and the sodium sulfide product is subjected to a preliminary cooling and drying process.

[0016] Preferably, the liquid cooling component includes a cooling water pipeline and cooling water nozzles. The cooling water pipeline is arranged above the cold rotary kiln, and at least one cooling water nozzle is arranged at equal intervals on the cooling water pipeline.

[0017] The other end of the cooling water pipeline is connected to an external cooling water storage device, so that the cooling water is evenly sprayed on the surface of the cold rotary kiln through the cooling water nozzle, and the kiln body is fully cooled, thereby performing a second cooling and drying process on the sodium sulfide product in the kiln body.

[0018] Preferably, the inner feeding screw is preset inside the cold rotary kiln.

[0019] The design of the internal feeding screw makes it take 2 minutes for the sodium sulfide product to go from the feed to the discharge port, and the slow discharge ensures the cooling effect of the product.

[0020] Preferably, the dust collecting air duct is arranged at the sodium sulfide discharge port.

[0021] The dust collecting duct is connected to the external dust collecting system, so as to collect dust and other impurities generated when the sodium sulfide product is discharged, thus reflecting the environmental protection of the device.

[0022] The beneficial effects of the utility model are:

[0023] When the utility model is in use, the design of the air cooling component and the liquid cooling component forms a double cooling process for the sodium sulfide product, thereby achieving the purpose of rapidly cooling the sodium sulfide product, not only improving the production efficiency, but also improving the product quality, which is then conducive to promotion and use.
