[0039] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a dust removal device for HVAC engineering construction, comprising a main shell 1, a water tank 2, a suction fan body 3, an air suction pipe 4 and an air outlet pipe 5; the water tank 2 and the suction fan body 3 are both fixedly arranged inside the main shell 1, one end of the suction fan body 3 passes through the main shell 1 and is connected to the outside through the air suction pipe 4, and the other end is connected to the water tank 2 through the air outlet pipe 5; the air suction pipe 4 comprises a suction section 4.1 and a filter section 4.2 arranged along the gravity direction, and the suction section 4.1 is connected to the filter section 4.2; a filter assembly 4.3 is installed in the filter section 4.2, and the filter assembly 4.3 comprises an interception net 4.31 and a weighing sensor 4.32, the weighing sensor 4.32 is fixedly arranged in the filter section 4.2, and the interception net 4.31 is arranged above the weighing sensor 4.32 and can slide along the length direction of the filter section 4.2; the interception area of ​​the interception net 4.31 is matched with the cross-sectional area of ​​the filter section 4.2.

[0042] Through the above settings, the suction fan provides suction to suck dust from the external area into the water tank, so that the dust removal operation can be carried out quickly and conveniently. Through the setting of the filter component, larger waste materials can be filtered out and temporarily stored in the suction pipe. After accumulating to a certain extent and reaching the weight detected by the weighing sensor, the operator is promptly reminded to clean the filter component. Such a setting can ensure timely cleaning after filtering out large particles of waste materials, and will not affect the suction force of the suction fan, thereby improving the efficiency and life of the dust removal device.

[0043] refer to Figure 2 and Figure 4 The filter section 4.2 is also provided with a slot 4.5, and the slot 4.5 is provided with a cover plate 4.6 for opening or closing the slot 4.5; the slot 4.5 and the cover plate 4.6 are arranged at the installation position of the filter assembly 4.3. By improving the arrangement of the slot and the cover plate, the filter section of the suction pipe can be quickly opened for cleaning.

[0044] The cover plate 4.6 is an arc-shaped cover plate matching the filter section 4.2, and the arc-shaped cover plate is hinged with the card slot 4.5. The arc-shaped cover plate is matched with the filter section and is used to restore the pipe shape of the filter section after installation, so as to facilitate the interception net to slide smoothly in the filter section.

[0045] In one embodiment, in order to enhance the sealing performance of the connection between the arc-shaped cover plate and the filter section, a sealing member 4.7 is further provided between the clamping groove 4.5 and the arc-shaped cover plate.

[0046] refer to Figure 5 The filter assembly 4.3 further comprises a limit ring 4.33, a spring 4.34 and a guide column 4.35; the limit ring 4.33 is fixedly arranged on the inner wall of the filter section 4.2, and a plurality of weighing sensors 4.32 are evenly arranged on the top of the limit ring 4.33; the limit ring 4.33 is also provided with a guide hole 4.36 along the length direction of the filter section 4.2, and the interception net 4.31 of this embodiment is also provided with a fixing ring 4.38, by which nets of different apertures are fixed, so that interception nets of different specifications can be obtained according to needs. The fixing ring 4.38 of the intercepting net 4.31 is also provided with a guide post 4.35 matching the guide hole 4.36, and the guide post 4.35 is used to slide in the guide hole 4.36; the guide post 4.35 and the guide hole 4.36 are arranged at the interval of the weighing sensor 4.32; the spring 4.34 is sleeved on the guide post 4.35, and its two ends are respectively in contact with the limit ring 4.33 and the intercepting net 4.31. Through the above arrangement, the intercepting net is guided when it slides in the filter section relative to the weighing sensor, so as to avoid getting stuck. At the same time, the fixing ring of the intercepting net will only contact the weighing sensor after reaching the set pressure and breaking through the elastic force of the spring, which can prevent the intercepting net from frequently colliding with the weighing sensor when intercepting debris, thereby protecting the weighing sensor.

[0047] The main housing 1 is also provided with a warning light 6, and the weighing sensor 4.32 is electrically connected to the electric control end of the warning light 6. The warning light and the filter assembly can be used to timely remind the operator to clean the filter assembly and ensure the normal operation of the dust removal device.

[0048] In one embodiment, a retaining ring 4.37 is fixedly connected to the limiting ring 4.33, so as to limit the movable range of the intercepting net.

[0049] In one embodiment, in order to facilitate the inspection and maintenance of the interior of the main housing 1, the main housing 1 is further provided with a protective plate 1.1 for opening and closing the main housing 1. The main housing 1 is hinged to the protective plate 1.1 5, and a handle 1.2 is fixedly connected to the protective plate 1.1 for convenient opening and closing. Through the above arrangement, it is convenient to open the main housing for cleaning and inspection inside.

[0050] refer to Figure 3 The water tank 2 is also connected with a water injection pipe 2.2 and a drainage pipe 2.1, and valves 2.3 are installed on the water injection pipe 2.2 and the drainage pipe 2.1. In this embodiment, the suction fan body provides suction to discharge the dust adsorbed by the suction pipe into the water tank together with the air for dust reduction treatment. One side of the water tank is connected with a water injection pipe and a drainage pipe respectively. The water injection pipe is used to inject clean water into the water tank, and the drainage pipe is used to discharge sewage. Valves are installed on the water injection pipe and the drainage pipe to facilitate and quickly treat sewage.

[0051] A dust collector head 4.4 is installed at one end of the suction section 4.1. The maximum and minimum suction forces and the dust collection area can be adjusted conveniently by setting dust collector heads of different specifications.

[0052] When the present invention is working, the suction fan body 3 is started, and the suction pipe 4 is held to perform adsorption and dust removal treatment on the designated area. The dust enters the suction section 4.1 under the influence of suction force, and enters the filter section 4.2 through the suction section 4.1. Larger debris is intercepted by the interception net 4.31, and other debris passes through the suction fan body 3 with the air flow, and the debris and the air flow are discharged into the water tank 2 through the air outlet pipe 5 through the suction fan body 3. Clean water is pre-injected into the water tank 2 through the water injection pipe 2.2, so that the clean water in the water tank 2 is mixed with dust and debris to reduce dust and remove After cleaning, open the valve 2.3 of the drain pipe 2.1 to discharge the sewage. After the suction fan body 3 stops running, if there are too many large-volume debris on the interception net 4.31, it will drive the interception net 4.31 to fall, drive the fixing ring 4.38 to squeeze the weighing sensor 4.32. When the weighing sensor 4.32 detects that the weight of the debris carried on the interception net 4.31 exceeds the standard, the warning light 6 is started to prompt the user to clean it, open the protective plate 1.1, and remove the arc cover 4.6 to clean the debris and dust on the interception net 4.31.

[0053] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should all be included in the protection scope of the present invention.
