[0039] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[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 utility model provides a dust removal device for HVAC engineering construction, including 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 is connected to the outside through the air suction pipe 4 passing through the main shell 1, and the other end is connected to the water tank 2 through the air outlet pipe 5; the suction pipe 4 includes a suction section 4.1 and a filter section 4.2 arranged along the gravity direction, and the suction section 4.1 and the filter section 4.2 are connected; a filter assembly 4.3 is installed in the filter section 4.2, and the filter assembly 4.3 includes an intercepting net 4.31 and a weighing sensor 4.32, and the weighing sensor 4.32 is fixedly arranged in the filter section 4.2, and the intercepting 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 intercepting area of ​​the intercepting 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 the 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 further provided with a slot 4.5, which is provided with a cover 4.6 for opening or closing the slot 4.5. The slot 4.5 and cover 4.6 are located at the installation location of the filter assembly 4.3. The improved arrangement of the slot and cover allows for quick opening of the filter section of the suction pipe for cleaning.

[0044] The cover plate 4.6 is a curved cover plate that matches the filter section 4.2 and is hinged to the slot 4.5. The curved cover plate matches the filter section and is used to restore the pipe shape of the filter section after installation, thereby facilitating the smooth sliding of the interception net within 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 includes a limiting ring 4.33, a spring 4.34 and a guide column 4.35; the limiting ring 4.33 is fixedly arranged on the inner wall of the filter section 4.2, and the weighing sensors 4.32 are evenly arranged in multiple groups on the top of the limiting ring 4.33; the limiting ring 4.33 is also provided with guide holes 4.36 along the length direction of the filter section 4.2. The interception net 4.31 of this embodiment is also provided with a fixing ring 4.38, which fixes nets of different apertures through the fixing ring, 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 that matches the guide hole 4.36. The guide post 4.35 is used to slide within the guide hole 4.36. The guide post 4.35 and the guide hole 4.36 are arranged at the interval between the weighing sensor 4.32. The spring 4.34 is mounted on the guide post 4.35, and its two ends respectively abut against the limit ring 4.33 and the intercepting net 4.31. Through the above arrangement, the intercepting net is guided relative to the weighing sensor as it slides within the filter section, thereby preventing it from 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. This 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 terminal of the warning light 6. The warning light cooperates with the setting of the filter assembly to promptly 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 to limit the movable range of the intercepting net.

[0049] In one embodiment, to facilitate 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 and the protective plate 1.1 are hingedly connected 5, and a handle 1.2 is fixedly connected to the protective plate 1.1 for convenient opening and closing. This arrangement facilitates opening the main housing for cleaning and inspection of the interior.

[0050] refer to Figure 3 The water tank 2 is also connected to an inlet pipe 2.2 and a drain pipe 2.1, both of which are equipped with valves 2.3. In this embodiment, the suction fan body provides suction to discharge dust adsorbed by the suction pipe along with the air into the water tank for dust reduction treatment. An inlet pipe and a drain pipe are connected to one side of the water tank. The inlet pipe is used to inject clean water into the water tank, and the drain pipe is used to discharge wastewater. Both the inlet pipe and the drain pipe are equipped with valves to facilitate and quickly dispose of wastewater.

[0051] A dust collecting head 4.4 is installed at one end of the suction section 4.1. By setting dust collecting heads of different specifications, it is convenient to adjust the maximum and minimum suction forces and the dust collecting area.

[0052] When the utility model is working: the suction fan body 3 is started, and the suction pipe 4 is held by hand to perform adsorption and dust removal processing 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. The larger debris is intercepted by the interception net 4.31, and the other debris passes through the suction fan body 3 with the air flow, and the debris and 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 the dust and debris to reduce dust. After dust removal, 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, driving 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 activated to prompt the user to clean it, open the protective plate 1.1, and remove the curved cover 4.6 to clean the debris and dust on the interception net 4.31.

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