Description

Technical Field

[0001] This utility model relates to the field of construction dust treatment technology, and in particular to a dust filtration device for road engineering. Background Technology

[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining and managing roads, as well as the engineering entities involved. During the construction of road projects, a lot of dust is inevitably generated. This dust is easily inhaled by workers, and inhaled dust can have a serious impact on the lungs. Therefore, dust filtration devices are installed at construction sites to filter and treat the dust.

[0003] Application No.: CN202122112939.5 discloses a road engineering dust filtration device, the technical solution of which includes: a box body, a solar panel installed on the top of the box body, an air inlet on one side wall of the box body, a filter plate below the air inlet, a water pump installed on one side inner wall of the box body, a water supply pipe connected to the output end of the water pump, and a fan installed on the inner side of the filter plate. This utility model has a compact and novel structure, reduces the volume of the treatment box, facilitates fixed installation and mobile use, has high flexibility of use, and is suitable for use on construction sites.

[0004] Currently, when dealing with dust in road construction projects, dust filtration devices are used to draw in and filter the dust. However, most of these dust filtration devices have independent intake ports, which results in low dust intake and filtration efficiency. Consequently, a large number of dust filtration devices often need to be deployed at road construction sites. Therefore, we propose a dust filtration device for road construction projects. Utility Model Content

[0005] The main objective of this invention is to provide a road construction dust filtration device. This device uses three sets of side-mounted pipes at the E-shaped through-hole to support three sets of induced draft fans, allowing the filtration device to introduce dust generated during road construction from multiple locations. The dust is then filtered and trapped by the filter bags and filter discs within the device, effectively reducing dust hazards during road construction and eliminating the need for numerous dust filtration devices at construction sites. This effectively solves the problems described in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A road construction dust filtration device includes a base frame, an E-shaped through-type seat, side support plates, an induced draft fan, an L-shaped through-type seat, a cover plate, connecting blocks, and a fork plate. The base frame has rollers installed at its bottom and an E-shaped through-type seat welded to its top. Side support plates are welded to the three sets of side seat tubes of the E-shaped through-type seat, and an induced draft fan for dust extraction is installed on the surface of the side support plates. L-shaped through-type seats are welded to the upper seat openings of the E-shaped through-type seats, and a cover plate is bolted to the top of the vertical seat plate of the L-shaped through-type seat. A top mounting opening is vertically provided at the L-shaped through-type seat below the cover plate, and the lower surface of the cover plate is connected by connecting blocks. A fork plate is welded to the upper vertical seat opening of the L-shaped through seat. The surface of the fork plate has a U-shaped fork for inserting a metal ring. An arc-shaped pressure plate is welded above the metal ring and presses against the fork plate. A magnetic block for magnetically attracting the fork plate is embedded in the lower part of the plate away from the metal ring. A filter bag extending into the vertical seat cavity inside the L-shaped through seat is fixed at the lower ring opening of the metal ring. A concave rake frame is vertically welded to the surface of the fork plate away from the arc-shaped pressure plate and blocks the lateral seat cavity inside the L-shaped through seat. A filter sheet is inserted into the groove of the concave rake frame.

[0008] Furthermore, the seven sets of vertical frames of the concave rake frame are recessed with grooves, and the size of the grooves of the concave rake frame is the same as the size of the filter sheet.

[0009] By adopting the above technical solution, the vertical frame of the concave rake frame is installed with a mesh plate that is inserted into the filter plate through a groove.

[0010] Furthermore, the E-shaped through seat has three sets of rectangular side seat tubes at the seat opening, and the E-shaped through seat has an inner rising wall with an arc rising on the seat wall facing its own upper seat opening.

[0011] By adopting the above technical solution, the three sets of rectangular side seat tubes of the E-shaped through seat can fix the side support plate, and then the side support plate can be used to install the induced draft fan. After the air enters the E-shaped through seat, it can go up along the inner lifting wall and enter the L-shaped through seat.

[0012] Furthermore, the mounting base plate of the induced draft fan and the side support plate are locked together by bolts, and the air outlet of the induced draft fan faces the side seat tube of the E-shaped through seat.

[0013] By adopting the above technical solution, the mounting plate of the induced draft fan is installed by bolting it to the outside of the side support plate, and then the induced draft fan can blow air into the side seat tube of the E-shaped through seat.

[0014] Furthermore, the four corners of the bottom of the base plate of the base frame are bolted with upper wheel frames with rollers, and the four sets of frame rods of the base frame are welded to the bottom of the E-shaped through seat;

[0015] By adopting the above technical solution, rollers can be installed at the bottom of the frame plate to obtain a movable structure, while the top of the frame is supported by four sets of frame rods welded with E-shaped through seats.

[0016] Furthermore, a rectangular groove is recessed below the body of the arc-shaped pressure plate, and a magnetic block is inserted and bonded into the rectangular groove of the arc-shaped pressure plate.

[0017] By adopting the above technical solution, the arc-shaped pressure plate inserts the adhesive magnetic block into the rectangular groove, and then the arc-shaped pressure plate can be magnetically attached to the surface of the fork plate for fixation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a filtration device for filtering road construction dust. The filtration device uses three sets of side seat pipes at the E-shaped through seat to install three sets of exhaust fans with side support plates. This allows the filtration device to introduce dust generated by road construction from multiple points. The dust can then be filtered and trapped by the filter bags and filter sheets inside the filtration device, effectively reducing the dust hazards during road construction.

[0020] Furthermore, the filter bags and filter discs of the filtration device form a double-channel filtration structure at the L-shaped support, and the filter bags and filter discs of the filtration device can be easily removed for cleaning and replacement after the cover plate is removed.
