In recent years, mineral sizers have been widely used in coal, mining, construction, chemical and other fields, and have become the main equipment for crushing ore materials. However, in the course of mineral sizers, the temperature of roller bearings increases continuously. In order to ensure the reliability of their operation, it is necessary to cool the bearings. In addition, the crushing operation of materials produces a large amount of dust, which causes pollution to the environment and does not meet the requirements of environmental protection.
A mineral sizers bearing cooling device is designed to cool the roller bearing with cooling water and to pipe the wastewater flowing through the roller bearing seat into the mineral sizers material chute to spray and dust the crushed material, thus ensuring the reliability of the crusher operation. And meet the purpose of environmental protection requirements.
To achieve the above purposes, the following technical solution is adopted: A mineral sizers bearing cooling device with a cooling water flow line and a nozzle, matched by a cooling chamber reserved in the mineral sizers bearing seat: The inlet end of the cooling water flow pipe is connected to the cooling water source. The front part of the cooling water flow pipe goes into the bearing seat cooling chamber of mineral sizers through parallel branch pipes. The rear part of the cooling water flow pipe goes into the material chute of mineral sizers through the bearing seat cooling chamber and is fixed on the side wall of the material chute: The nozzle is installed at the rear of the cooling water circulation pipeline, and the nozzle nozzle points to the inside of the material chute, and the wastewater flowing through the bearing seat is sprayed on the material circulating in the material chute through the nozzle. [0006] The mineral sizers bearing cooling device is provided with a water temperature gauge and a cooling water flow control valve on the cooling water flow pipe; The water temperature gauge is installed in the rear of the cooling water flow pipe: the cooling water flow control valve is installed in the front of the cooling water pipe inlet end. The mineral sizers bearing cooling device forms a three-sided semi-enclosed structure at the rear of the cooling water circulation pipe along the side wall of the material chute. The mineral sizers bearing cooling device has not less than nine groups of nozzles uniformly distributed on the three-sided semi-enclosed structure at the rear of the cooling water circulation pipe.
We provide a mineral sizers bearing cooling device, matching with which a cooling chamber is reserved for the mineral sizers bearing seat at the time of casting. In the utility model, the cooling water flow pipe passes through the cooling chamber of the bearing seat, and the inlet end of the cooling water flow pipe is connected to the cooling water source. The rear part is arranged along the side wall of the material chute in mineral sizers, and several groups of nozzles are arranged at the rear of the cooling water circulation pipe. After the cooling water flows through the cooling chamber of the bearing seat, the broken material in the material chute is sprayed through the nozzles, which makes the dust generated in the crushing process sink, thus reducing the dust pollution. It can be seen that the utility model cools the roller bearing by cooling water, and then uses the wastewater flowing through the roller bearing seat to spray and dust down the crushed materials, achieving the purpose of ensuring the reliability of the crusher and meeting the requirements of environmental protection.
