Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, and more specifically, the utility model relates to a ventilation duct anti-blocking and dust-removing mechanism. Background Technique

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. When the central air-conditioning is in use, ventilation ducts need to be arranged for ventilation guidance. In order to filter and remove dust from the ventilation ducts, generally, filter plates need to be installed inside the ventilation ducts for dust removal and filtration.

[0003] In the existing dust-removing ducts, the dust-removing net often needs to be cleaned and maintained to ensure the cleaning effect, so it is more troublesome in daily use;

[0004] The Chinese patent with the patent application number CN202220300240.3 discloses a ventilation duct with good dust-removing effect, including a ventilation duct body, a connection port, an installation box and a dust-removing net. In the utility model, a slide rail is installed on the top of the fixed plate, and the dust-removing net is slidably connected with the slide rail in an embedded manner. A handle is arranged below the fixed plate at the bottom of the dust-removing net, and the handle is fixedly connected with the fixed plate through bolts, so as to facilitate removing the dust-removing net for maintenance and replacement; a threaded rod is arranged on one side of the top of the fixed plate, and a cleaning box is installed on the surface of the threaded rod through a moving block and a connecting frame. The sliding block is threadedly connected with the threaded rod, and the sliding block is sleeved with the sliding rod. Moreover, gears are installed on the surface of the transmission shaft in the cleaning box, and a gear is connected to the bottom end of the connecting shaft inside the cleaning box, and the two gears are meshed with each other. Then, by starting the first motor and the second motor, the cleaning brush regularly cleans the surface of the dust-removing net, so as to ensure the dust-removing effect of the dust-removing net and reduce the number of maintenance times;

[0005] Then, it can be seen from the accompanying drawings of its specification that by controlling the rotation and up-and-down movement of the cleaning brush to clean and remove dust from the filter net, blockage is avoided. However, after the cleaning is completed, it is inconvenient to collect and clean the dust generated during cleaning, which easily causes the dust to adhere to the filter net repeatedly, affecting the use effect of filtering and dust removal. Moreover, through rotational cleaning, there are easily cleaning dead corners, affecting the cleaning effect. Content of the Utility Model

One end of the filter plate 2 is fixedly connected with a sealing plate 3 to facilitate the disassembly and cleaning of the filter plate 2. The bottom of the ventilation pipe 1 is fixedly connected with a machine box 7, and a dust suction pump 5 and an air pump 6 are respectively arranged on both sides of the machine box 7;

[0028] On the top of both sides of the filter plate 2, a dust suction box 10 and a jet box 11 are respectively arranged. Two sealing blocks 8 are fixedly connected to the bottom of the inner cavity of the ventilation pipe 1. On both sides of the ventilation pipe 1, stable bars 9 are symmetrically fixedly connected at positions corresponding to the dust suction box 10 and the jet box 11. On the opposite sides of the dust suction box 10 and the jet box 11, a first communication pipe 14 and a second communication pipe 15 are respectively arranged. By driving the dust suction pump 5 to control the first communication pipe 14, suction is generated inside the dust suction box 10, and the dust on the surface of the filter plate 2 can be sucked away. By starting the air pump 6 to inject gas into the jet box 11, the surface of the filter plate 2 can be blown and cleaned, improving the use effect. The stability of the up and down movement of the dust suction box 10 and the jet box 11 can be improved through the stable bars 9;

[0029] A fixing bar 16 is fixedly connected to the middle of the dust suction box 10, and a brush 17 is fixedly connected to one side of the fixing bar 16. A plurality of air jet holes 12 are provided on one side of the jet box 11. Driving mechanisms are arranged at the bottoms of the dust suction box 10 and the jet box 11. Through the driving mechanisms, the jet box 11 and the dust suction box 10 can be controlled to move up and down simultaneously, playing a driving role. And the surface of the filter plate 2 can be cleaned by the brush 17 when the dust suction box 10 moves up and down, improving the cleaning effect.

[0030] As shown in the attached Figure 2 As shown, the input end of the dust suction pump 5 is communicated with one end of the first communication pipe 14, one end of the first communication pipe 14 is communicated with the inner cavity of the dust suction box 10, the output end of the air pump 6 is communicated with one end of the second communication pipe 15, and one end of the second communication pipe 15 is communicated with the inner cavity of the jet box 11. Starting the dust suction pump 5 generates suction inside the dust suction box 10 to facilitate dust suction.

[0037] Specifically, starting the dust suction pump 5 can generate suction force inside the dust suction box 10. Starting the air pump 6 enables the air jet box 11 to eject gas through the air jet holes 12, so that the gas ejected from the air jet holes 12 can blow and clean one side of the filter plate 2, and the generated dust is absorbed and discharged through the dust suction box 10, realizing the function of dust cleaning and preventing blockage;

[0038] Meanwhile, the motor 21 is used to control the simultaneous up-and-down movement of the air jet box 11 and the dust suction box 10, so as to clean the surface of the filter plate 2, improve the cleaning effect, and thus enhance the anti-blocking effect.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
