Description

Technical Field

[0001] This utility model relates to the field of boiler technology, specifically a device for quickly removing the sealing material of the inner and outer tubes of a sootblower. Background Technology

[0002] Sealing packing is installed between the inner and outer tubes of the steam sootblower on the heating surface of the boiler in a thermal power plant. The sealing packing is an important sealing component in the sootblower system, used to prevent steam leakage and ensure the safe operation of the equipment. The packing is graphite packing, which has good high temperature resistance and self-lubricating properties, and can maintain a good sealing effect under high temperature and high pressure. There are a total of 6 packings between the inner and outer tubes of one sootblower, which are installed sequentially at the gap of the outer tube and fixed by pressure plate.

[0003] However, long-term operation can cause steam leakage between the inner and outer pipes due to packing wear, which can damage the equipment. When the outer pipe is worn and corroded and needs to be replaced, the packing also needs to be removed. Traditionally, packing removal is done manually and destructively, using a hammer and screwdriver to break the packing into pieces and remove the packing chamber. This affects the efficiency of replacement and may cause damage and deformation to the inner and outer pipes during the knocking process. Utility Model Content

[0004] The purpose of this invention is to solve the problem that long-term operation of packing wear leads to steam leakage between the inner and outer tubes, causing equipment damage. When the outer tube is worn and corroded and needs to be replaced, the packing also needs to be removed. Traditional packing removal only uses manual destructive removal, that is, using a hammer and screwdriver to break the packing bit by bit and then remove it from the packing chamber, which affects the replacement efficiency and may cause damage and deformation to the inner and outer tubes during the knocking process. This invention provides a device for quickly removing the sealing material of the inner and outer tubes of a sootblower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] The present invention relates to a quick removal device for sealing materials of inner and outer tubes of a sootblower, comprising a tube segment; one end of the tube segment is provided with multiple toothed grooves; and straight tube handles are symmetrically fixed to the outer surface of the tube segment.

[0007] Furthermore, a first nut is fixed to the outer surface of the tube segment; a second nut is fixed to the first nut.

[0008] Furthermore, the right angle of the tube segment is provided with a safety rounded corner.

[0009] This utility model provides a quick removal device for the sealing material of the inner and outer tubes of a sootblower, which has the following features:

[0010] Beneficial effects:

[0011] 1. This utility model involves attaching the tube segment to the outer surface of the outer tube, then holding the two straight tube handles with both hands and forcefully inserting the sealing packing along the outer tube, or using a tool to push the tube segment into the sealing packing, so that the toothed groove at the end of the tube segment is inserted into the sealing packing, and then holding the straight tube handles and rotating the tube segment to destroy the sealing packing, easily removing the sealing packing without damaging the structure of the soot blower.

[0012] 2. This utility model has a first nut and a second nut welded to the outer surface of the tube segment, which protrude a certain distance from the outer surface of the tube segment. This allows for hammering without damaging the outer tube of the soot blower during the hammering process. It also allows the toothed groove at the end of the tube segment to be inserted into the sealing material, thereby easily destroying the sealing material by rotating the tube segment.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-3 As shown, a quick removal device for the sealing material of the inner and outer tubes of a sootblower includes a tube 1 that fits into the outer tube of the sootblower; one end of the tube 1 has multiple toothed grooves 2; straight tube handles 3 are symmetrically fixed to the outer surface of the tube 1. By fitting the tube 1 into the outer surface of the outer tube, the user holds the two straight tube handles 3 with both hands and forcefully inserts them into the sealing material along the outer tube, or by using a tool to push the tube 1 into the sealing material, so that the toothed grooves 2 at the end of the tube 1 are inserted into the sealing material. Then, by holding the straight tube handles 3 and rotating the tube 1, the sealing material is destroyed, and the sealing material can be easily removed without damaging the structure of the sootblower.

[0023] A first nut 4 is fixed to the outer surface of the tube segment 1; a second nut 5 is fixed to the first nut 4. The first nut 4 and the second nut 5, which are welded to the outer surface of the tube segment 1, protrude a certain distance from the outer surface of the tube segment 1, so that a hammer can be used to strike it. This prevents damage to the outer tube of the soot blower during the striking process, and allows the toothed groove 2 at the end of the tube segment 1 to be inserted into the sealing material. Thus, the sealing material can be easily destroyed by rotating the tube segment 1.

[0024] The right angle of the tube segment 1 is provided with a safety rounded corner 6. The safety rounded corner 6 makes it safer to hold the straight tube handle 3, and it can also maintain safety during long-term use without scratching the area between the thumb and forefinger.

[0025] A curved handle 7 is fitted onto the straight handle 3. The curved handle 7 allows for one-handed gripping and rotation of the tube 1, enabling one-handed use and stable single-handed movement, and preventing the toothed groove 2 from easily moving and injuring the body.

[0026] The tube segment 1, straight tube handle 3, first nut 4 and second nut 5 are fixedly connected by welding. The welding method ensures high overall structural strength, preventing deformation under stress when cleaning sealant and allowing for long-term use in cleaning sealant.

[0027] The tube segment 1, straight tube handle 3, first nut 4 and second nut 5 are made of metal, which makes the structure strong and can withstand stress without deformation when cleaning sealant, and can be used for cleaning sealant for a long time.
