Description

Technical Field

[0001] The utility model relates to the technical field of ventilation duct cleaning, and more specifically to a self-cleaning ventilation duct. Background Art

[0002] Flash drying equipment is commonly used in the pharmaceutical field. Its function is to convert substances in liquids or suspensions into powders or dry solids. Flash drying equipment needs to use ventilation ducts to discharge moisture during use. Dirt, residues or scaling in the ventilation ducts may block the flow and affect the normal operation of the flash drying equipment. The ventilation ducts need to be cleaned regularly.

[0003] After searching, a patent document with the existing publication number CN220371832U provides a self-cleaning ventilation duct. The device starts a motor to drive the gear to rotate through a rotating shaft, so that the gear moves inside the gear groove. The two gears above and below the movable frame move inside the gear groove on the fixed bar, thereby driving the movable frame to move on the inner wall of the ventilation duct, and then driving the first cleaning brush and the second cleaning brush to contact the inner wall of the ventilation duct, thereby achieving the effect of automatic cleaning of the ventilation duct.

[0004] When cleaning the pipeline, the above-mentioned prior art only wipes the inner wall of the pipeline with a cleaning brush, which has poor dust adsorption capacity. During the cleaning process, dust will be generated in the pipeline, affecting the quality of pipeline cleaning.

[0005] In view of this, we propose a self-cleaning ventilation duct. Utility Model Content

[0028] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] See also Figure 1 ,The utility model provides a self-cleaning ventilation duct, comprising a connecting pipe section 1, a transmission pipe section 2 and a cleaning component 3;

[0030] The connecting pipe section 1 is hoisted on the top of the plant through a mounting rod, and the transmission pipe section 2 is fixedly installed between the two connecting pipe sections 1.

[0031] See also Figure 2 and Figure 3 The cleaning component 3 includes a water tank 301, an atomizer 302, a cleaning brush 303 and a driving motor 304; when the ventilation duct needs to be cleaned, the atomizer 302 installed inside the connecting pipe section 1 is operated by remote control, and the atomized water generated by the atomizer 302 enters the transmission pipe section 2 under the carrying of the flowing air, wets the inner wall of the transmission pipe section 2, avoids dust during the cleaning process, and increases the dust adsorption effect of the cleaning brush 303.

[0032] Then the driving motor 304 is controlled to rotate, and the output end of the driving motor 304 drives the bevel gear 305 to rotate. The bevel gear 305 engages and drives the bevel gear ring 306 to rotate in the connecting pipe section 1, so that the cleaning brush 303 fixed on one side of the bevel gear ring 306 rotates.

[0033] The cleaning brush 303 is rotatably arranged inside the transmission pipe section 2. The cleaning brush 303 is arranged in a spiral shape and has a length greater than the length of the transmission pipe section 2. The end of the cleaning brush 303 can extend into the connecting pipe section 1. The cleaning brush 303 is made of carbon steel and is sheathed with a polyurethane sponge on the outside. Figure 4 When the driving motor 304 drives the cleaning brush 303 to rotate, the rotation direction of the cleaning brush 303 is opposite to its spiral direction.

[0034] When the cleaning brush 303 is rotating, the polyurethane sponge layer on its outside can absorb the dust inside the transmission pipe section 2 and push the dust toward the air outlet of the transmission pipe section 2 .

[0035] A water storage chamber 101 is provided at the bottom of the connecting pipe section 1, and a filter plate 102 is provided above the water storage chamber 101. The filter plate 102 is plugged into the connecting pipe section 1, and the filter plate 102 is made of antibacterial filter cotton; when the cleaning brush 303 pushes dust or sewage into the connecting pipe section 1, the antibacterial filter cotton on the filter plate 102 can adsorb the dust, and when the antibacterial filter cotton comes into contact with water, it will release antibacterial agents to achieve a sterilization effect, thereby preventing the dust and sewage accumulated in the connecting pipe section 1 from polluting the air in the ventilation duct.

[0036] Moreover, a limit rod is fixedly installed near the air outlet in the transmission pipe section 2, and a roller 201 is rotatably connected to the outer side of the limit rod, and the roller 201 is in frictional contact with the cleaning brush 303; during the rotation of the cleaning brush 303, the roller 201 can squeeze the cleaning brush 303 to cause it to shrink, and when the end of the cleaning brush 303 is separated from the roller 201, the cleaning brush 303 can be quickly extended. By utilizing the extension and retraction of the cleaning brush 303, the cleaning effect of the cleaning brush 303 on the inner wall of the transmission pipe section 2 can be increased. At the same time, inertia can also be utilized to discharge the sewage and dust in the cleaning brush 303 to maintain the cleaning effect of the cleaning brush 303.
