Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant fans, in particular to a wear-resistant fan. Background Art

[0002] Wear-resistant fans are high-strength, high-wear-resistant, and high-efficiency fan equipment that is widely used in various industrial environments. Wear-resistant fans are mainly used to transport gas or steam from one place to another and have a wide range of applications, including cement plants, metallurgical plants, mines, power plants, etc. In these industrial productions, wear-resistant fans are usually used to discharge and circulate gas, and their working conditions are often very harsh, such as high temperature, high pressure, corrosion, and wear.

[0003] Wear-resistant fans usually adopt a centrifugal structure. Their working principle is: when the fan is started, the drive device drives the impeller to rotate, the gas is sucked into the impeller and is affected by the centrifugal force, thereby accelerating the movement. As the gas speed increases, the kinetic energy of the airflow also increases, and eventually wind pressure is generated. This wind pressure can be used to transport gas, ventilate or for other purposes in process production.

[0004] At present, the simplest way to prevent wear on the inside of the volute of the casing in the industry is to increase the thickness of the volute plate and directly stick a wear-resistant ceramic lining on the inside of the volute. Ceramic gaskets can be installed in the air duct. Usually, ceramic gaskets can be installed at the flange connection, elbow or other parts of the air duct that require sealing, heat insulation or wear resistance. First of all, ceramic gaskets have excellent properties such as high temperature resistance, corrosion resistance and wear resistance. These properties make ceramic gaskets widely used in occasions that need to withstand harsh environments such as high temperature, high pressure and corrosive media. Inside the air duct, if there is high temperature, high-speed airflow or corrosive media, ceramic gaskets can be used as an effective sealing, heat insulation or wear-resistant material.

[0005] However, in the prior art, the volute tongue part of the fan is most severely worn due to the huge air volume. Once the ceramic lining is replaced, it needs to be removed from the fan, which wastes resources. In addition, it is inconvenient to take and place the lining. Since the ceramic lining is usually fixed to the equipment with bolts or other fasteners, these fasteners need to be removed and installed one by one when taking it out, which increases the complexity of the operation. Utility Model Content

[0006] In view of the problem of inconvenience in replacing the above-mentioned ceramic lining plate, the present utility model is proposed.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a wear-resistant fan, comprising a shell, a fixing box provided on the inner surface of the shell, a ceramic lining plate plugged into the surface of the fixing box, and a clamping assembly for clamping and fixing the ceramic lining plate provided on the surface of the fixing box;

[0010] As a preferred solution of the wear-resistant blower of the utility model, one end of the rotating rod is fixedly connected to an impeller, and a bottom plate is provided at the bottom of the motor.

[0011] As a preferred solution of the wear-resistant blower of the utility model, the surface of the bottom plate is fixedly connected to the inner surface of the shell, and a front observation door and a rear observation door are respectively installed on the outside of the shell.

[0012] As a preferred solution of the wear-resistant blower of the utility model, wherein: the bottom of the shell is fixedly connected to a base, and both sides of the base are fixedly connected to a No. 1 threaded fixing plate.

[0013] As a preferred solution of the wear-resistant fan of the utility model, wherein: No. 2 threaded fixing plates are fixedly connected to both sides of the fixing box, an insert block is fixedly connected to one side of the fixing box, and a socket is opened on the other side of the fixing box.

[0014] Beneficial effects of the utility model:

[0015] 1. This new and practical method uses a fixing box, a ceramic lining plate and a clamping assembly. The staff clamps the ceramic lining plate into the fixing box. When the ceramic lining plate is clamped into the fixing box, the spring is squeezed and deformed, driving the extrusion head to squeeze and contract into the main rod, so that the spring squeezes and contacts the ceramic lining plate to achieve rapid clamping, which has the advantage of high installation efficiency. Compared with the traditional installation method, this installation method is simpler and more convenient, avoiding the need to remove all ceramic lining plates from the casing once they are replaced, which wastes resources.

[0016] 2. At the same time, the traction rope, fixed pulley and pull rod are coordinated, and the traction rope can drive the extrusion head to move. Through the pull rod and the pull rope, several extrusion heads on the same side can be driven to retract toward the inner wall of the fixed box, thereby further facilitating the rapid placement of the ceramic lining into the fixed box and also facilitating the rapid removal of the ceramic lining from the fixed box.

When the liner is worn to a certain extent or damaged, it can be quickly and conveniently replaced, which can greatly reduce equipment downtime and ensure the continuous operation of the production line, thereby improving production efficiency. The easy-to-replace ceramic liner design makes maintenance work simple and quick. When replacement is required, it can be completed in a few simple steps without the need for complicated disassembly and installation processes, thereby reducing the complexity and cost of maintenance. In addition, since downtime and maintenance difficulty are reduced, production losses caused by equipment downtime are also indirectly reduced.
