TECHNICAL FIELD

[0001] The utility model belongs to the dangerous waste incineration application technical field, concretely relates to a rotor support structure of dry method deslagging cooling machine. BACKGROUND

[0002] With the high speed development of world industrialization and city economy, the generation of dangerous waste also increases sharply, which causes serious harm to human body, soil, water and the like. The treatment of dangerous waste is a process of decomposing the harmful substances to harmless components or transforming into the chemical form with less toxicity through one or more physical and chemical means. The basic principle of the dangerous waste pollution prevention and control technology policy is the reduction, resource utilization and harmlessness of dangerous waste.

[0003] At present, the disposal of dangerous waste often adopts rotary kiln pyrolysis and secondary combustion chamber incineration. In this dangerous waste incineration system, the high-temperature ash after the secondary combustion chamber incineration enters the dry method deslagging cooling machine at the rear end. However, due to the variety of raw materials and the complexity of chemical properties, the large block of gelatinous material is easily formed after incineration. When entering the disc cooler, it will have a great impact on the rotor, even cause equipment failure, and affect the normal operation of the production line.

[0004] Therefore, based on the above problems, the utility model provides a rotor support structure of dry method deslagging cooling machine. SUMMARY

[0005] The utility model discloses a rotor support structure of dry method deslagging cooling machine to solve the problem that the large block of material impacts the rotor and causes equipment failure, and guarantee the normal operation of the production line.

[0006] Technical scheme: the utility model provides a rotor support structure of dry method deslagging cooling machine, which is composed of a bearing, a bearing seat, a rack, a roller support, a plurality of rollers, a rotor, a lining plate, a rotor body and a main shaft. The bearing seat is fixed on the rack, the bearing is installed in the bearing seat, and the rotor is installed on the main shaft and rotates with the main shaft. The lining plate is installed on the bottom surface of the rotor body. The rollers are evenly distributed in the circumferential direction of the rack. The rollers are supported below the lining plate, and the friction force between the rollers and the lining plate is rolling friction.

[0007] In the technical scheme, the rollers respectively include a roller sleeve, a roller bearing and a roller shaft. The roller shaft is fixed on the roller support, and the roller sleeve rotates on the roller shaft through the roller bearing.

[0008] In the technical scheme, the rotor support structure of the dry method deslagging cooling machine further includes a lubrication system for regularly supplementing lubricating medium to the roller bearing in the roller.

[0009] The rotor supporting structure of the dry method slag discharge cooling machine further comprises a bolt pair, and the lining plate is mounted on the outer edge of the bottom surface of the rotor body through the bolt pair.

[0010] Compared with the prior art, the rotor supporting structure of the dry method slag discharge cooling machine has the following beneficial effects: 1. The carrier roller bears the load in the vertical direction of the rotor body, and the stress state of the bearing is better, and the carrier roller is not prone to heating and other conditions during operation; 2. When large pieces of material fall on the rotor body from above, the instantaneous impact force is large, and the carrier roller below can ensure that the rotor body does not tilt to cause deformation of the rotor body, thereby affecting the operation of the equipment.

Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0017] The utility model is further illustrated below in combination with the drawings and specific embodiments.

[0018] As shown in Figure 1 and Figure 2 A rotor supporting structure of a dry method slag discharging cooler, which is composed of a bearing 1, a bearing seat 2, a rack 3, a roller support 4, a lubricating system 5, a roller 6, a roller sleeve 61, a roller bearing 62, a roller shaft 63, a lining plate 71, a bolt pair 72, a rotor body 73, a rotor 7 and a main shaft 8.

[0019] The bearing seat 2 is fixed on the rack 3, the bearing 1 is installed in the bearing seat 2, and the rotor 7 is installed on the main shaft 8 and rotates together with the main shaft 8.

[0020] The lining plate 71 is installed on the outer edge of the bottom surface of the rotor body 73 through the bolt pair 72, and when the lining plate 71 is obviously worn after being used for a period of time, the lining plate 71 can be replaced.

[0021] A plurality of rollers 6 are evenly installed in the circumferential direction of the rack 3, the roller 6 includes the roller sleeve 61, the roller bearing 62 and the roller shaft 63, the roller shaft 63 is fixed on the roller support 4, and the roller sleeve 61 can rotate on the roller shaft 63 through the roller bearing 62.

[0022] The roller 6 is supported below the lining plate 71, and the friction force between the roller 6 and the lining plate 71 is rolling friction force, which has very small resistance to the rotation of the rotor.

[0023] In addition, the lubricating system 5 can periodically supplement the lubricating medium in the roller bearing 62 of the roller 6, so as to ensure the long-term reliable rotation of the roller 6.

[0024] In the operation process of the device (dry slagging cooling machine), the material falls from the upper part to the upper part of the rotor body 73. When the production becomes abnormal, the oversized material falls from the high place to the upper part of the rotor body 73, which will cause a great impact on the rotor body 73, and in severe cases, the rotor body 73 will be deformed, thereby affecting the normal operation of the device.

[0025] The several supporting rollers 6 arranged below the rotor body 73 can reliably support the outer edge of the rotor body 73 when the large block material falls on the rotor body 73, thereby avoiding the deformation of the rotor body 73, and enabling the rotor 7 to operate stably.

[0026] It should be noted that in this document, such as the term "comprise", "include" or any other variant thereof is intended to cover the non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes the elements inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including a" does not exclude the existence of another identical element in the process, method, article or device including the element.

[0027] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
