It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, and decoration construction. The place where construction work is carried out is called the "construction site" or "construction site". Construction is a production activity carried out by people using various building materials and machinery and equipment in a certain space and time according to specific design blueprints to build various building products. Construction sites are often filled with a lot of dust, which affects the health of workers. Generally, dust removal devices can be used to reduce the health threats posed by dust.

[0003] Currently, in the process of using existing dust removal equipment for building construction, wire mesh is usually installed at one end of the air inlet pipe to protect it. However, since the wire mesh is installed and fixed with screws, it is very inconvenient to disassemble. As the equipment is used for a long time, a lot of dust will enter the air inlet pipe, causing a lot of dust to adhere to the wire mesh. However, since the wire mesh is difficult to disassemble, cleaning becomes very troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for building construction, which aims to solve the problem that existing dust removal devices for building construction usually install wire mesh at one end of the air inlet pipe to protect it. However, since the wire mesh is fixed by screws, it is very inconvenient to disassemble. With long-term use of the device, a large amount of dust will enter the air inlet pipe, causing a lot of dust to adhere to the wire mesh. However, since the wire mesh is difficult to disassemble, it is very troublesome to clean.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust removal device for building construction, comprising a housing, an air inlet pipe connected to one end of the housing, an air outlet pipe connected to one end of the housing, a fan installed inside the air outlet pipe, a base connected to the bottom of the housing, and a filter plate extending laterally through its outer wall.

A fixing block is connected to the top of the protective mesh plate, and a slot is provided at the end of the fixing block. A mounting base is connected to the top of the air inlet pipe, and a bidirectional lead screw passes through one end of the mounting base. Two threaded sleeves are threaded to the outer wall of the bidirectional lead screw, and L-shaped inserts are connected to the outer walls of the two threaded sleeves. A guide rod is connected inside the mounting base.

[0007] As a preferred embodiment of the dust removal device for building construction according to this utility model, the slot is adapted to the size of one end of the L-shaped plug.

[0008] As a preferred embodiment of the dust removal device for building construction according to this utility model, one end of the L-shaped insert is sleeved on the outer wall of the guide rod.

[0009] As a preferred embodiment of the dust removal device for building construction according to this utility model, one end of the bidirectional lead screw is connected to the mounting base through a bearing to form a rotating connection structure.

[0010] As a preferred embodiment of the dust removal device for building construction according to this utility model, a slide rail is provided on the inner side of the outer shell, a handle is installed on one end of the filter plate, a connecting seat is connected to the outer wall of the outer shell, a spring is provided inside the connecting seat, a movable block is connected to one end of the spring, and a limit pin is connected to one end of the movable block.

[0011] As a preferred embodiment of the dust removal device for building construction according to this utility model, the filter plate can be slidably connected to the outer shell via a slide rail.

[0012] As a preferred embodiment of the dust removal device for building construction according to this utility model, the limiting pin can form an elastic structure with the connecting seat through a spring and a movable block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By rotating the double-ended screw counterclockwise, the two threaded sleeves on its outer wall can drive the L-shaped inserts to move in opposite directions along the guide rod. As the two L-shaped inserts move, one end will disengage from the slot at the end of the fixed block, thus enabling the protective mesh to be easily disassembled for cleaning by staff.

[0015] By moving the movable block with the lever, the limiting pin retracts. At this time, one end of the limiting pin will move away from the end of the filter plate. Then, by pulling the filter plate with the handle, the filter plate will move outward along the slide rail, thus making it easy to disassemble the filter plate. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-6 The present invention provides the following technical solution: a dust removal device for building construction, including a shell 1, an air inlet pipe 2 connected to one end of the shell 1, an air outlet pipe 3 connected to one end of the shell 1, a fan 4 installed inside the air outlet pipe 3, a base 5 connected to the bottom of the shell 1, and a filter plate 6 penetrating through the outer wall of the shell 1.

[0026] One end of the air inlet pipe 2 is provided with a positioning notch 7. A protective mesh plate 8 is provided on the inner side of the air inlet pipe 2. A fixing block 9 is connected to the top of the protective mesh plate 8. A slot 10 is provided at the end of the fixing block 9. A mounting base 11 is connected to the top of the air inlet pipe 2. A two-way screw rod 12 passes through one end of the mounting base 11. Two threaded sleeves 13 are threadedly connected to the outer wall of the two-way screw rod 12. An L-shaped insert 14 is connected to the outer wall of the two threaded sleeves 13. A guide rod 15 is connected inside the mounting base 11.

[0027] It should be noted that fan 4 has an external power supply and control switch connected.

[0028] Preferably, the slot 10 is adapted to the size of one end of the L-shaped plug 14, one end of the L-shaped plug 14 is sleeved on the outer wall of the guide rod 15, and one end of the bidirectional lead screw 12 is connected to the mounting base 11 through a bearing to form a rotating connection structure.

[0029] In practical use, by rotating the double-acting screw 12 counterclockwise, the two threaded sleeves 13 on its outer wall can drive the L-shaped insert 14 to move in opposite directions along the guide rod 15. As the two L-shaped inserts 14 move, one end of them will disengage from the slot 10 at the end of the fixing block 9, thereby enabling the protective mesh plate 8 to be easily disassembled for cleaning by staff.

[0030] During installation, the protective mesh plate 8 is first embedded inside the air inlet pipe 2 so that the fixing block 9 can enter the positioning notch 7. Then, by rotating the double-acting screw 12 clockwise, the two threaded sleeves 13 on its outer wall can drive the L-shaped insert 14 to move towards each other along the guide rod 15. As the two L-shaped inserts 14 move, one end of them will be inserted into the slot 10 at the end of the fixing block 9.

[0031] Preferably, a slide rail 16 is provided on the inner side of the outer shell 1, a handle 17 is installed on one end of the filter plate 6, a connecting seat 18 is connected to the outer wall of the outer shell 1, a spring 19 is provided inside the connecting seat 18, a movable block 20 is connected to one end of the spring 19, and a limit pin 21 is connected to one end of the movable block 20. The filter plate 6 can form a sliding connection structure with the outer shell 1 through the slide rail 16, and the limit pin 21 can form an elastic structure with the connecting seat 18 through the spring 19 and the movable block 20.

[0032] In practical use, the movable block 20 is moved by the lever to retract the limiting pin 21. At this time, one end of the limiting pin 21 will move away from the end of the filter plate 6. Then, the filter plate 6 is pulled by the handle 17, and the filter plate 6 will move outward along the slide rail 16, so that the filter plate 6 can be easily disassembled.

[0033] Working principle: First, by starting the fan 4, dust generated during building construction enters the interior through the air inlet duct 2. After being filtered by the filter plate 6, it is discharged through the air outlet duct 3. By rotating the double-acting screw 12 counterclockwise, the two threaded sleeves 13 on its outer wall can drive the L-shaped inserts 14 to move in opposite directions along the guide rod 15. As the two L-shaped inserts 14 move, one end of them will disengage from the slot 10 at the end of the fixing block 9, thus enabling the protective mesh plate 8 to be easily disassembled for cleaning by workers. At the same time, by using the lever to move the movable block 20, the limiting pin 21 will retract. At this time, one end of the limiting pin 21 will move away from the end of the filter plate 6. Then, by pulling the handle 17, the filter plate 6 will move outward along the slide rail 16, thus enabling the filter plate 6 to be easily disassembled.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
