Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to a device for preventing the cathode wire of an electrostatic precipitator from falling off. Background Technology

[0002] Electrostatic precipitators are essential equipment in thermal power plants. Their function is to remove particulate matter from the flue gas emitted by stoves or oil-fired boilers, thereby significantly reducing the amount of dust emitted into the atmosphere. This is an important environmental protection device for improving environmental pollution and air quality.

[0003] During the operation of an electrostatic precipitator, the cathode wire vibrates when struck, which can easily cause the bolts at both ends of the cathode wire to come loose. Once the bolts come loose, the cathode wire will fall off, causing equipment failure and damage, and rendering the electrostatic precipitator unusable. Therefore, a cathode wire anti-detachment device for electrostatic precipitators is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cathode wire anti-detachment device for electrostatic precipitators, which solves the problems mentioned in the background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cathode wire anti-detachment device for an electrostatic precipitator includes a mounting frame, a fixing sleeve fixedly mounted on the opposite side of the mounting frame, an mounting block overlapping inside the fixing sleeve, an insert plate overlapping on the top of the mounting block, the surface of the insert plate overlapping with the inner wall of the fixing sleeve, a fixing component one on the top of the insert plate, a fixing component two on the left side of the fixing sleeve, and a cathode wire body fixedly mounted on the opposite side of the mounting block.

[0007] Preferably, the fixing component one includes a conical spring one fixedly disposed on the top of the insert plate, and a bolt one fixedly disposed on the top of the conical spring one, the threaded end of the bolt one penetrating the insert plate and the mounting block and being threaded onto the inner wall of the fixing sleeve.

[0008] Preferably, the fixing component two includes a conical spring two fixedly disposed on the surface of the fixing sleeve, a bolt two overlapping the right side of the conical spring two, the threaded end of the bolt two passing through the fixing sleeve and the mounting block and extending to the other side surface of the fixing sleeve where a nut is threadedly disposed, and the right side of the nut is fixedly disposed to the surface of the fixing sleeve.

[0009] Preferably, a limiting plate is fixedly provided on the opposite side of the mounting block, and the surface of the limiting plate overlaps with the inner wall of the fixing sleeve and the inner wall of the insert plate.

[0010] Preferably, a limiting strip is fixedly provided on the top of the insert plate, and the limiting strip is made of metal.

[0011] Preferably, there are two of each of the conical springs and bolts, and the conical springs and bolts are symmetrically distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-detachment device for the cathode wire of the electrostatic precipitator, through the cooperation of a limiting plate, an insert plate, bolt one, bolt two, and a nut, provides multi-directional contact and fixation of the mounting block, preventing the mounting block from falling off from the top and sides of the fixing sleeve. By setting conical spring one and conical spring two between bolt one and the insert plate and between bolt two and the fixing sleeve, the bending and twisting deformation of conical spring one and conical spring two generates clamping pressure acting on the insert plate and the fixing sleeve, increasing the friction between bolt one and the insert plate and between bolt two and the nut, ensuring a reliable connection between them, and preventing the cathode wire from falling off and causing equipment failure and damage, thus preventing the electrostatic precipitator from operating normally.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-4A cathode wire anti-detachment device for an electrostatic precipitator includes a mounting frame 1. A fixing sleeve 2 is fixedly mounted on the opposite side of the mounting frame 1. A mounting block 3 is overlapped inside the fixing sleeve 2. An insert plate 5 is overlapped on the top of the mounting block 3. A limit strip 12, made of metal, is fixedly mounted on the top of the insert plate 5. The limit strip 12 facilitates the removal of the insert plate 5 during disassembly. The surface of the insert plate 5 overlaps with the inner wall of the fixing sleeve 2. A fixing component 1 is provided on the top of the insert plate 5. The fixing component 1 includes a conical spring 6 fixedly mounted on the top of the insert plate 5. A bolt 7 is fixedly installed on the top of the conical spring 6. The threaded end of the bolt 7 passes through the insert plate 5 and the inner wall of the mounting block 3 and the fixing sleeve 2. There are two conical springs 6 and two bolts 7, and they are symmetrically distributed. Through the cooperation of the bolt 7 and the insert plate 5, the top and side of the mounting block 3 are simultaneously limited and fixed to prevent the mounting block 3 from falling out of the fixing sleeve 2. A fixing component 2 is provided on the left side of the fixing sleeve 2. The cathode wire body 11 is fixedly installed on the opposite side of the mounting block 3. The fixing component 2 includes a fixing... A conical spring 8 is installed on the surface of the fixed sleeve 2. A bolt 9 is overlapped on the right side of the conical spring 8. The threaded end of the bolt 9 passes through the fixed sleeve 2 and the mounting block 3 and extends to the other side of the fixed sleeve 2. A nut 10 is threaded thereon. The right side of the nut 10 is fixed to the surface of the fixed sleeve 2. The mounting block 3 is more stable through the cooperation of the conical spring 8, the bolt 9, and the nut 10. This anti-detachment device for the cathode wire of the electrostatic precipitator, through the cooperation of the limiting plate 4, the insert plate 5, the bolt 7, the bolt 9, and the nut 10, provides multi-directional adhesion to the mounting block 3. The mounting block 3 is fixed in place, preventing it from falling off the top and sides of the fixing sleeve 2. Conical springs 6 and 8 are installed between bolt 7 and insert plate 5 and between bolt 9 and fixing sleeve 2. The bending and twisting deformation of conical springs 6 and 8 generates clamping pressure on insert plate 5 and fixing sleeve 2, increasing the friction between bolt 7 and insert plate 5 and between bolt 9 and nut 10. This ensures a reliable connection between them and prevents the cathode wire from falling off, causing equipment failure and damage, and preventing the electrostatic precipitator from operating normally.

[0020] In use: First, place the cathode wire between the two mounting frames 1, so that the mounting block 3 and the limiting plate 4 are inserted into the fixed sleeve 2 from above. Then, screw the second bolt 9 through the second conical spring 8, the fixed sleeve 2 and the mounting block 3 and screw it into the nut 10. Then, insert the insert plate 5 into the fixed sleeve 2 so that it fits against the mounting block 3, the limiting plate 4 and the fixed sleeve 2. Finally, screw the first bolt 7 through the first conical spring 6, the insert plate 5 and the mounting block 3 and screw it into the inner wall of the fixed sleeve 2 to complete the installation.
