Description

Technical Field

[0001] The utility model relates to the technical field of wet electric demisters, in particular to a maintenance tool for an anode tube of a wet electric demister. Background Art

[0002] At present, wet electrostatic demister is usually used for dust control of flue gas acid production, which is mainly used to reduce dust and acid mist in the exhaust gas. Since hydrogen peroxide absorption desulfurization process is used in the exhaust gas desulfurization treatment process, long-term use will lead to corrosion of fiberglass on the surface of the anode tube and fuzzing on the inner surface of the anode tube. Conductive resin is generally used to repair the fiberglass corrosion on the surface of the anode tube.

[0003] The wet electrostatic demister itself is a small confined space. The anode tube is installed in the electrostatic demister. The anode tube is a parallelepiped tubular structure with a small space. After the glass fiber reinforced plastic on the surface of the anode tube is corroded, conductive resin is usually applied to the upper or lower part of the anode tube for protective maintenance. However, due to the long length of the anode tube and the parallelepiped tubular structure in a small space, it is inconvenient to apply the conductive resin to the inner surface of the anode tube, and the middle part of the anode tube cannot be applied with conductive resin due to its long length. After the anode tube has been corroded for a long time, it can only be replaced as a whole, which is costly. Summary of the invention

[0004] The utility model aims to solve the problem that it is inconvenient to apply conductive resin to the inner surface of the anode tube and the conductive resin cannot be applied to the middle part of the anode tube in the prior art, and provides a maintenance tool for the anode tube of a wet electric demister. The tool is convenient for applying conductive resin to the inner surface of the anode tube and can apply conductive resin to the middle part of the anode tube, thereby achieving the effect of maintaining the anode tube and extending the service life of the anode tube.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a maintenance tool for anode tubes of wet electric demisters, including a handle tube and a fixed column, the lower end of the handle tube is connected to the fixed column, two maintenance components are symmetrically arranged on the fixed column, the maintenance components include a movable support rod, a spring and a roller brush, the upper end of the movable support rod is hinged to the bottom of the fixed column, the lower end of the movable support rod is fixedly provided with a roller brush shaft, the roller brush shaft is vertically arranged at the end of the movable support rod, and the roller brush is rotatably sleeved on the roller brush shaft. The roller brush is used to adhere to the conductive resin and apply the conductive resin to the inner surface of the anode tube. Under the action of the handle tube, the inner surface of the anode tube can be coated with the conductive resin, thereby achieving the effect of maintaining the heat-insulating anode tube.

[0006] The spring is located outside the movable support rod, and both ends of the spring are fixedly connected with spring hooks, and the two spring hooks are respectively connected to the fixed column and the movable support rod. The two maintenance components are symmetrically installed on the fixed column, and under the action of the spring, when the roller brushes of the two maintenance components enter the anode tube to apply the conductive resin, the movable support rod drives the roller brush to automatically receive force outward, and the roller brush can fully contact the inner surface of the anode tube, thereby improving the maintenance effect of the anode tube.

[0007] Furthermore, the upper end of the handle tube is provided with a handle, and the lower end is provided with a threaded column. The handle is convenient for the staff to apply the conductive resin to the inner surface of the anode tube.

[0008] Furthermore, a threaded hole matching the threaded column is formed on the top of the fixing column, and the threaded column is detachably connected to the fixing column by threads.

[0009] Furthermore, two U-shaped seats are arranged at intervals at the bottom of the fixed column, a pin is fixedly arranged on the U-shaped seat, and a connecting plate is arranged at the upper end of the movable support rod, and the connecting plate is rotatably sleeved on the pin. The purpose is to tighten the movable support rod outward under the action of the spring, and at the same time change the angle between the two movable support rods to adapt to anode tubes with different aperture sizes.

[0010] Furthermore, a first hanging ear is symmetrically arranged on the outer side of the fixed column, a second hanging ear is fixedly arranged on the lower part of the movable support rod, and the two spring hooks are hung on the first hanging ear and the second hanging ear respectively.

[0013] The utility model adopts a roller brush to adhere the conductive resin, and the conductive resin can be applied to the inner surface of the anode tube by the roller brush; the conductive resin can be applied to the inner surface of the anode tube by the handle tube.

[0014] The two maintenance components of the utility model are relatively installed, and can simultaneously apply resin to the inner surface of the anode tube.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] like Figure 1 to Figure 4 As shown, a maintenance tool for anode tubes of wet electric demisters includes a handle tube 3 and a fixed column 1. The lower end of the handle tube 3 is connected to the fixed column 1. Two maintenance components are symmetrically arranged on the fixed column 1. The maintenance components include a movable support rod 9, a spring 12 and a roller brush 15. The upper end of the movable support rod 9 is hinged to the bottom of the fixed column 1. The lower end of the movable support rod 9 is fixedly provided with a roller brush shaft 14. The roller brush shaft 14 is vertically arranged at the end of the movable support rod 9. The roller brush 15 is rotatably sleeved on the roller brush shaft 14. In this embodiment, the handle tube 3 is used to increase the handle when applying conductive resin to ensure that the inner surface of the anode tube can be coated with conductive resin. The movable support rods 9 of the two maintenance components form an "eight"-shaped movable bracket. The roller brush 15 is used to adhere the conductive resin so as to apply the conductive resin to the inner surface of the anode tube.

[0022] The spring 12 is located outside the movable support rod 9, and both ends of the spring 12 are fixedly connected with spring hooks 13, and the two spring hooks 13 are respectively connected to the fixed column 1 and the movable support rod 9. In this embodiment, the spring 12 can make the roller brush 15 fully contact with the inner surface of the anode tube to achieve the effect of applying the conductive resin to the inner surface of the anode tube, and the spring 12 can change the angle between the two maintenance component movable support rods 9, so as to apply the conductive resin to the anode tubes with different aperture sizes.

[0023] The handle tube 3 is provided with a handle 4 at the upper end and a threaded column 5 at the lower end. In this embodiment, the handle 4 is welded and fixed to the upper end of the handle tube 3 so that the staff can apply conductive resin to the anode tube, and the threaded column 5 is used to connect the fixing column 1.

[0024] A threaded hole 2 matching the threaded column 5 is formed on the top of the fixing column 1 , and the threaded column 5 is detachably connected to the fixing column 1 by threads.

[0025] Two U-shaped seats 7 are arranged at intervals at the bottom of the fixed column 1, and a pin shaft 8 is fixedly arranged on the U-shaped seat 7. A connecting plate 10 is arranged at the upper end of the movable support rod 9, and the connecting plate 10 is rotatably sleeved on the pin shaft 8. In this embodiment, an axial hole matching the pin shaft 8 is opened on the connecting plate 10, and the connecting plate 10 is sleeved on the pin shaft 8 through the axial hole.

[0027] The working principle of the utility model is as follows: first, the roller brushes 15 of the two maintenance components are adhered with conductive resin, and then the staff can hold the handle 4 to put the roller brushes 15 of the two maintenance components into the parallel hexagonal anode tube. After the roller brushes 15 are put into the anode tube, under the action of the spring 12, the movable support rod 9 drives the roller brush 15 to automatically be forced outward, and the two roller brushes 15 are in full contact with the inner surfaces of both sides of the anode tube. Then the staff can push the maintenance component downward, and the roller brush 15 rolls downward on the inner surfaces of both sides of the anode tube to achieve the purpose of applying the conductive resin to the inner surface of the anode tube. After the work of applying the conductive resin to the inner surfaces of both sides of the anode tube is completed, the above operation is repeated twice, and the conductive resin is applied to the inner surfaces of the other four sides of the anode tube. Then the work of applying the conductive resin to the anode tube can be completed, so as to achieve the effect of maintaining the anode tube and extend the service life of the anode tube.
