[0025] like Figure 1As shown, in an embodiment of the present invention, the filter screen blowing device includes: an air intake duct 10 and a plurality of nozzles 30. The air intake duct 10 is used to be arranged in a hot air chamber 100 of a tunnel-type shredded stem drying machine. The plurality of nozzles 30 are arranged in sequence along the extension direction of the length of the air intake duct 10. Each nozzle 30 is connected to the air intake duct 10. The nozzle 30 faces the filter screen 101 of the hot air chamber 100 to blow dust out of the filter screen 101.

[0026] Specifically, the tunnel-type shredded stem drying machine includes a drying zone 1 and a drying zone 2, both of which are frame structures, and each drying zone is provided with a hot air chamber 100, which is used to dry the shredded stems, and the shredded stems are vibrated and turned in the hot air chamber 100 to use hot air to dry the shredded stems. A plurality of filters 101 are provided on opposite sides of the hot air chamber 100, and the filters 101 are used to filter dust during the turning process of the shredded stems. Since the shredded stems have a certain amount of moisture, water vapor entering the filters 101 during the drying process will cause dust to condense on the filters 101, thereby affecting the discharge of moisture.

[0027] In this embodiment, an air intake duct 10 is provided in the hot air chamber 100, and the air intake duct 10 is used to introduce compressed air into the hot air chamber 100. A plurality of nozzles 30 are provided on the air intake duct 10, so that the compressed air can be ejected from the nozzles 30. The nozzles 30 are directed toward the filter 101, so that dust on the filter 101 can be blown off, so as to prevent the dust from condensing on the mesh of the filter 101 under the action of water vapor, thereby clogging the mesh of the filter 101.

[0028] The filter screen blowing device provided in the embodiment of the utility model can introduce compressed air into the hot air chamber by setting an air intake duct and multiple nozzles. After the compressed air is sprayed out from the nozzles, it can blow off the dust on the filter screen, preventing the dust from condensing on the mesh of the filter screen under the action of water vapor, avoiding clogging of the mesh, and ensuring that the moisture discharge channel is unobstructed.

[0029] Further, in the embodiment of the present invention, the air intake duct 10 is arranged in parallel with the filter 101. Specifically, in the embodiment of the present invention, the filter 101 is arranged on opposite sides of the hot air chamber 100, so in the present embodiment, the number of the air intake ducts 10 is also two, and each air intake duct 10 is arranged adjacent to a row of filter 101 to blow off the dust on the filter 101 on one side.

When the nozzle 30 cannot swing, its sweeping area is limited and only the dust at the position opposite to it can be blown off. After the driving member is set, the driving member can drive the multiple nozzles 30 to swing up and down when rotating, so that the nozzles 30 can sweep the filter screen 101 from top to bottom in sequence, thereby increasing the sweeping area and improving the sweeping effect.

[0032] Furthermore, in an embodiment of the present invention, the driving member is a rotary cylinder.

[0033] The filter screen blowing device provided in the embodiment of the utility model can drive the nozzle to rotate by providing a driving member, thereby increasing the blowing area of ​​the nozzle, improving the blowing capacity, and ensuring the blowing effect.

[0036] Furthermore, each first swing arm 20 may also be rotatably connected to the air intake duct 10 to adjust the air outlet direction of each nozzle 30 .

[0037] Specifically, in this embodiment, the filter 101 has a certain arc shape. When the filter 101 filters dust, some parts are prone to dust accumulation, while some parts are not. In view of this situation, the direction of each nozzle 30 can be adjusted so that the air outlet direction of the nozzle 30 is opposite to the part prone to dust accumulation, thereby improving the purging effect of the part prone to dust accumulation and ensuring that the moisture discharge channel is unobstructed.

[0038] like Figure 2 As shown, in an embodiment of the utility model, the filter purge device also includes a second swing arm 40, the air intake duct 10 is vertically arranged and connected to the second swing arm 40, and a plurality of nozzles 30 are provided on the second swing arm 40, and each nozzle 30 is connected to the second swing arm 40, wherein the air intake duct 10 is rotatably connected to the top of the hot air chamber 100.

When the air intake pipe 10 swings, it can drive the second swing rod 40 to swing. A plurality of nozzles 30 are arranged on the rod body of the second swing rod 40 opposite to the filter 101. When the air intake pipe 10 rotates, it drives the second swing rod 40 to swing like a pendulum. When the nozzle 30 on one side is close to the filter 101, the filter 101 can be purged.

[0042] In the embodiment of the utility model, the filter screen purging device further comprises an air storage mechanism and a valve. The air storage mechanism is connected to the air intake pipeline 10 through a pipeline, and the valve is arranged on the pipeline.
