Description
Technical Field
[0001] The utility model belongs to the technical field of carbon ring sealing groove cleaning machinery, and in particular relates to a cleaning device for carbon ring sealing grooves. Background Art
[0002] The rotating parts of gas turbine expanders or gas compressors usually use carbon ring sealing technology for mechanical sealing. Due to the presence of various impurities in the gas, such gas equipment will regularly clean the rotor blades. However, the rotor body is generally not hoisted during the maintenance process, so it is difficult to clean the annular sealing groove at the bottom of the rotor. In order to facilitate the maintenance and cleaning of the sealing groove, the sealing groove used to assemble the carbon ring mostly adopts a split structure, that is, the annular sealing groove is assembled from two or more arc-shaped sealing grooves. This structure enables the sealing groove to be easily disassembled and assembled, but due to the structural characteristics of the sealing groove, even if the arc-shaped sealing grooves are disassembled one by one, it is difficult to clean the impurities inside. If it is not cleaned thoroughly, it will have a certain impact on the sealing effect of the replaced carbon ring. In severe cases, it will cause gas leakage, leading to safety hazards. Therefore, a cleaning device that can conveniently and effectively remove impurities from the carbon ring sealing groove is now needed. Utility Model Content
[0003] The utility model aims to provide a cleaning device for a carbon ring sealing groove, which can quickly and effectively remove impurities in the carbon ring sealing groove.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A cleaning device for a carbon ring sealing groove comprises a cleaning table, a cleaning groove arranged on the cleaning table and adapted to the arc-shaped sealing groove to be cleaned, an elastic cleaning strip pressed into the cleaning groove in a detachable manner, and a thrust mechanism slidably arranged on the cleaning groove and capable of pushing the elastic cleaning strip into the arc-shaped sealing groove to be cleaned.
[0006] A further improvement of the technical solution of the utility model is that the cleaning tank comprises a plurality of arc-shaped grooves which are concentrically arranged on the surface of the cleaning table, and at least one end of the arc-shaped grooves passes through to the outside of the cleaning table.
[0007] A further improvement of the technical solution of the utility model is that the cleaning table is a semicircular plate-shaped structure, and a plurality of arc-shaped grooves are concentrically arranged on the cleaning table surface in a semicircular shape.
[0008] A further improvement of the technical solution of the utility model is that the thrust mechanism includes a thrust block slidably arranged in each arc groove and a thrust handle detachably arranged on the thrust block, and the elastic cleaning strip is pressed into the arc groove, and one end of the elastic cleaning strip contacts the thrust block.
[0009] A further improvement of the technical solution of the utility model is that a steel wire is arranged inside the elastic cleaning strip along its length direction.
[0010] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is that the impurities in the carbon ring sealing groove can be quickly and effectively removed, the air tightness of the carbon ring seal can be improved, and potential safety hazards can be effectively eliminated.
[0011] The utility model adopts a cleaning groove provided with a plurality of concentrically arranged arc grooves, that is, the plurality of arc grooves have different sizes. An operator can choose to press the elastic cleaning strip into a suitable arc groove for cleaning operation according to the size of the arc sealing groove to be cleaned, which is more flexible and practical. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural schematic diagram of the cleaning device of the utility model;
[0013] Among them, 1. an arc-shaped sealing groove to be cleaned, 2. a cleaning table, 3. an elastic cleaning strip, 4. an arc-shaped groove, 5. a push block, and 6. a thrust handle. DETAILED DESCRIPTION
[0014] The present invention is further described in detail below in conjunction with the embodiments:
[0015] like Figure 1 As shown, a cleaning device for a carbon ring sealing groove comprises a cleaning table 2, a cleaning groove and a thrust mechanism arranged on the cleaning table 2, wherein the cleaning groove can be adapted to the arc-shaped sealing groove 1 to be cleaned. When cleaning is required, the elastic cleaning strip 3 can be pressed into the cleaning groove in a detachable manner, and the elastic cleaning strip 3 is in a compressed state when pressed into the cleaning groove. A thrust mechanism is slidably arranged on the cleaning groove, and the thrust mechanism contacts the elastic cleaning strip 3 clamped in the cleaning groove and pushes the elastic cleaning strip 3 into the arc-shaped sealing groove 1 to be cleaned. After entering the arc-shaped sealing groove 1 to be cleaned, the elastic cleaning strip 3 expands and pushes out the impurities inside the arc-shaped sealing groove 1 to be cleaned, thereby achieving a better cleaning effect.
[0016] The cleaning groove may be composed of a plurality of arc grooves 4 concentrically arranged on the surface of the cleaning table 2, or may be composed of vertical grooves of different lengths or L-shaped grooves of different sizes, or may be composed of grooves of other shapes that can adapt to arc-shaped sealing grooves 1 of different sizes to be cleaned, at least one end of the above grooves penetrates to the outside of the cleaning table 2, so that the elastic cleaning strip 3 pressed into the groove can enter the arc-shaped sealing groove 1 to be cleaned, and when both ends of the groove penetrate to the outside of the cleaning table 2, a stopper may be provided at one end thereof to stop the thrust mechanism and prevent the thrust mechanism from sliding out of the cleaning table 2. The operator may press the elastic cleaning strip 3 into the groove of the corresponding adapted size according to the size of the arc-shaped sealing groove 1 to be cleaned.
[0017] The cleaning table 2 is a plate-like structure with a certain thickness. Preferably, the cleaning table 2 is set to a semicircular plate-like structure that is adapted to the shape of the arc-shaped sealing groove 1 to be cleaned, and a plurality of arc-shaped grooves 4 are concentrically arranged in a semicircular shape on the semicircular table surface of the cleaning table 2. Of course, the cleaning table 2 can also be set to a rectangular plate-like structure or other shape structures, and the shape setting of the cleaning table 2 does not affect its function.
[0018] The thrust mechanism comprises a push block 5 slidably arranged in each arc groove 4 and a thrust handle 6 detachably arranged on the push block 5. The elastic cleaning strip 3 is pressed into the arc groove 4, and one end thereof contacts the push block 5. A steel wire may be arranged inside the elastic cleaning strip 3 along its length direction to make it have a certain rigidity so as to facilitate pushing by the push block.
