[0025] like Figure 1 and Figure 2 A dust removal device for the air inlet channel of an air shower includes a vertically arranged air inlet pipe 1. The air inlet pipe 1 is fixed to the outside of the air shower, or a separate chamber can be set inside the air shower shell, and the air inlet pipe 1 is installed in the independent chamber of the air shower.

[0026] A connecting port 101 is fixedly connected to one side of the top of the air inlet pipe 1. The connecting port 101 is used to communicate with the gas channel inside the air shower room, so that air can enter the air shower room during air shower. An air inlet 102 is fixedly connected to one side of the bottom of the air inlet pipe 1. The air inlet 102 is used for the entry of external air. The inner diameter of the connecting port 101 and the air inlet 102 are the same.

[0027] like Figure 1 and Figure 2 A rectangular frame portion 3 is provided on the air intake pipe 1 and located between the connecting pipe port 101 and the air intake pipe port 102. A filter screen 4 is provided inside the rectangular frame portion 3. A spray head 5 is fixedly installed on the top of the inner wall of the air intake pipe 1. The spray head 5 is used to spray clean water to clean the filter screen 4 and the inner wall of the air intake pipe 1. The spray head 5 is a shower head structure in the prior art, which can spray clean water more evenly.

[0028] like Figure 2The air intake pipe 1 is connected to the rectangular frame part 3. One side of the rectangular frame part 3 is designed with an opening, so that the filter screen 4 can be installed and removed from the opening side of the rectangular frame part 3.

[0029] like Figure 2 , Figure 3 and Figure 4 A fixing plate 6 is installed inside the rectangular frame part 3. The fixing plate 6 has a through hole 601. When the fixing plate 6 is installed in the rectangular frame part 3, the through hole 601 and the cavity inside the air intake pipe 1 are aligned in the vertical direction. The filter screen 4 is fixedly installed on the top of the fixing plate 6. The filter screen 4 can be installed on the fixing plate 6 by means of bolt fixing and snap-fit, and the filter screen 4 is set above the through hole 601. A sealing strip 7 is fixedly connected around the fixing plate 6 to ensure that the fixing plate 6 and the rectangular frame part 3 fit tightly.

[0030] like Figure 1 and Figure 3 A concave fixing plate 8 is fixedly connected to one side of the fixing plate 6. Mounting bolts 9 are provided on both sides of the concave fixing plate 8. Mounting screw holes 10 are provided on both sides of the rectangular frame part 3. The mounting bolts 9 pass through the concave fixing plate 8 and are threadedly connected to the mounting screw holes 10, which is used to install the filter screen 4 to the inner side of the rectangular frame part 3. The concave fixing plate 8 has through holes on both sides to facilitate the installation bolts 9 to pass through. The concave fixing plate 8 can fit against the outer side of the rectangular frame part 3, so that the mounting screw holes 10 and the through holes on the concave fixing plate 8 are aligned together, which can facilitate the installation and disassembly of the fixing plate 6 and the filter screen 4.

[0031] like Figure 1 and Figure 2 The top of the spray head 5 is fixedly connected to a clean water inlet pipe 11. The top of the clean water inlet pipe 11 extends to the outside of the air inlet pipe 1 and is used to connect to an external clean water input pipe. The external clean water input pipe has a water pump to boost the pressure, which can boost the water and deliver it to the spray head 5 through the clean water inlet pipe 11, thereby increasing the water pressure sprayed out by the spray head 5 and enabling better spray cleaning of the filter screen 4.

[0032] like Figure 2 The bottom of the air intake pipe 1 is fixedly connected to a receiving sleeve 12, and a sewage drain pipe 13 is fixedly connected to one side of the receiving sleeve 12, which can discharge the sewage that falls into the receiving sleeve 12.

[0033] like Figure 2 An air inlet water seal ring 14 is fixedly connected to the inner wall of the air inlet 102, and a connecting pipe water seal ring 15 is fixedly connected to the inner wall of the connecting pipe 101. The air inlet water seal ring 14 can prevent the water sprayed from the spray head 5 from overflowing into the external environment along the inner wall of the air inlet pipe 1 and the inner wall of the air inlet 102.

[0034] The water-stop ring 15 at the connecting pipe port can prevent water sprayed from the spray head 5 from overflowing into the air shower room along the inner wall of the air inlet pipe 1 and the inner wall of the connecting pipe port 101.

[0035] An air intake protection net 16 is fixedly installed at one end of the air intake port 102. The air intake protection net 16 is a large-diameter filter screen used to prevent debris from entering the interior of the air intake pipe 1 through the air intake port 102.

[0036] The working principle of the dust removal device for the air inlet channel of the air shower provided by this utility model is as follows:

[0037] When air intake is required, outside air enters the air intake pipe 1 through the air intake port 102. After the dust is filtered out by the filter screen 4, it enters the external air shower room through the connecting pipe port 101.

[0038] When it is necessary to remove dust from the filter screen 4, or when it is necessary to disassemble and replace the filter screen 4, the external water pump can be started to input clean water into the spray head 5 through the clean water inlet pipe 11, and then sprayed out from the spray head 5. The sprayed clean water washes away the dust adsorbed on the filter screen 4. At the same time, the sprayed water can also flow along the inner wall of the air inlet pipe 1 to clean the inner wall of the air inlet pipe 1. The pollution formed after the clean water washes away the dust falls into the receiving sleeve 12 and is discharged from the sewage drain pipe 13.

[0039] The water sprayed onto the filter screen 4 can also wet the filter screen 4, causing the residual dust on the surface of the filter screen 4 to adhere to the filter screen 4. At this time, the removal of the filter screen 4 will not cause the dust to escape.

[0040] Compared with related technologies, the dust removal device for the air inlet channel of the air shower provided by this utility model has the following beneficial effects:

[0041] This invention uses a spray head 5 to spray clean water to clean the inner wall of the air intake pipe 1 and the filter screen 4 located inside the air intake pipe 1. This can achieve more thorough cleaning of the dust on the surface of the filter screen 4, reduce the frequency of filter screen disassembly and cleaning, and when disassembling or replacing the filter screen 4, water can be sprayed to wet the filter screen 4 first, so that the residual dust on the surface of the filter screen 4 adheres to the filter screen 4, and prevents the dust from escaping into the interior of the air shower room during the disassembly process.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
