Description

Technical Field

[0001] The utility model belongs to the technical field of equipment lubrication and cooling, and specifically discloses a steam calcining furnace support wheel lubrication and cooling device. Background Art

[0002] Steam calcining furnace is a type of drum-type reaction equipment that uses steam to indirectly heat the material in the production of soda ash to cause a decomposition reaction. It consists of a furnace body, alkali inlet, alkali outlet, heating and transmission devices. The furnace body is a cylinder made of steel plates rolled and welded. There are two rollers in front and behind the furnace body, which are mounted on two supporting wheels. The furnace body is tilted backward by 1.5% to 2%. A gear ring is installed near the roller ring at the tail of the furnace. The furnace body is driven to rotate by an electric motor through a reducer, a floating coupling, and a gear ring. Screw conveyors are used for both the alkali inlet and alkali outlet. Heavy alkali (sodium bicarbonate) and return alkali are added to the furnace by a feeder. As the furnace body rotates, they are indirectly heated by the steam in the heating tube. The heavy alkali is decomposed into soda ash. The generated soda ash is discharged by a screw conveyor, and a part of it is returned to the furnace as return alkali.

[0003] The supporting wheel plays a supporting role in the summary of all accessories of the steam calciner. During the operation of the supporting wheel, good lubrication is the key to ensure the safe operation of the steam calciner. Due to the characteristics of high load, continuous operation and high temperature environment of the supporting wheel, pitting is prone to appear on the surface of the supporting wheel, that is, pitting. When the pitting area is small, it will not greatly hinder the operation of the steam calciner. If it develops, there will be slag and block falling, cracks, serious uneven wear, polygons or small ripples, etc., causing the steam calciner to vibrate and fail to maintain the normal operation of the steam calciner. In order to solve this problem, lubricants and some cooling measures are generally used to protect it. When lubricating, it is generally necessary to stop or disassemble the device for lubrication protection. However, due to the high cost of the supporting wheel and the wheel tyre, it is not easy to replace. If replacement is required, the entire device needs to be stopped, affecting the production progress. In view of the above problems, we propose a steam calciner supporting wheel lubrication and cooling device. Utility Model Content
