Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device with an easy-to-disassemble and install filter screen. Background Technology

[0002] With the development of urbanization in my country, the requirements for environmental pollution control are increasing, and strict standards have been formulated for exhaust gas emissions. At present, the common method of exhaust gas purification is to directly filter industrial exhaust gas generated by industrial sites. Large particles in the flue gas are intercepted or adsorbed by the filter screen, or the reactants on the filter screen react with the chemical substances in the flue gas, thereby achieving flue gas purification.

[0003] Existing exhaust gas treatment devices are inconvenient for staff to replace internal filters, resulting in low work efficiency and difficulty in maintaining components. This utility model device facilitates the disassembly and replacement of internal filters and the maintenance and replacement of component parts. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas treatment device that facilitates the disassembly and assembly of the filter screen, thereby solving the problems of inconvenience in replacing the filter screen and inconvenience in maintaining the component parts.

[0005] To achieve the above objectives, a waste gas treatment device with an easy-to-install and remove filter screen is provided, comprising: a treatment box, a second mounting plate fitted onto the upper surface of the treatment box, an installation groove formed on the upper surface of the second mounting plate, two limiting plates slidably connected inside the installation groove, one end of each of the two limiting plates being inserted into the treatment box, two limiting sliding grooves formed on the inner wall of the installation groove, a pushing block slidably connected between the opposite sides of the two limiting plates, limiting rods fixedly connected to both sides of the pushing block, the end of each limiting rod away from the pushing block being slidably connected to the inside of the limiting sliding groove, a pushing bolt rotatably connected inside the pushing block, the lower end of the pushing bolt being threadedly connected to the inside of the second mounting plate, and a filter screen connected to the lower surface of the second mounting plate by screws, facilitating the disassembly and replacement of the filter screen by operators and reducing the difficulty of disassembly;

[0006] Both of the aforementioned limiting slides have limiting blocks fitted into their upper ends, and four second screws are inserted into the upper ends of both of the aforementioned limiting blocks. The lower ends of the second screws are connected to the internal threads of the second mounting plate, making it convenient for workers to remove the pushing block and the pushing bolt for maintenance or replacement.

[0007] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, the longitudinal section of the limiting block is T-shaped and the longitudinal section of the pushing block is an isosceles trapezoid, which facilitates the downward movement of the pushing block and simultaneously pushes the limiting plate to move.

[0008] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, the side surface of the filter screen is fitted to the inside of the treatment box to ensure the installation is airtight.

[0009] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, the discharge pipe is fixedly connected to one side of the treatment box, and the inlet box is fixedly connected to the other side of the treatment box. A connecting pipe is fixedly connected to the side of the inlet box to facilitate the entry of exhaust gas and its discharge after filtration.

[0010] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, the upper surface of the inlet box is fitted with a first mounting plate, the lower surface of the first mounting plate is fixedly connected to an air intake fan, and the side surface of the air intake fan is in close contact with the inner wall of the inlet box to facilitate the guidance of exhaust gas into the box.

[0011] According to the exhaust gas treatment device with easy-to-disassemble filter screen, two first screws are inserted into the upper surface of the first mounting plate, and the lower end of the first screws is threaded into the inside of the box, which facilitates the fixing of the first mounting plate and makes it convenient for the staff to replace the internal air intake fan.

[0012] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, the two limiting plates are symmetrically arranged, and the two limiting rods are symmetrically arranged, so as to conveniently limit the second mounting plate through the limiting rods.

[0013] According to the exhaust gas treatment device that facilitates the disassembly and assembly of the filter screen, a connecting flange is fixedly connected to the end of the connecting pipe away from the inlet box.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. By rotating the push bolt, the push block can be moved down synchronously. The limit rod and the limit slide groove prevent the push block from rotating synchronously with the push bolt. The inclined surface of the push block cooperates with the inclined surface at one end of the limit plate, which facilitates the push block to push the limit plate to move, making it easier for staff to disassemble and replace the filter screen and reducing the difficulty of disassembly.

[0016] 2. By removing the second screw, it is easy to release the second screw from the limit block. The limit block is used to release the blockage of the limit slide, making it easy for staff to remove the push block and push bolt for maintenance or replacement.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
