Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, and particularly relates to an on-site control cabinet for premix assembly. Background Art

[0002] Premix is the abbreviation of additive premixed feed. It is an intermediate compound feed product made by proportioning one or more trace elements (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs and other additives) with a diluent or carrier as required and uniformly mixing them. Premix needs to be fully mixed with other feeds before feeding. The mixing process is generally automatically stirred by a stirring device. Since there is dust at the premix assembly site and the control cabinet for automatic stirring needs to dissipate heat, dust enters the interior of the cabinet from the heat dissipation inlets and outlets. Content of the Utility Model

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a on-site control cabinet for premix assembly, including a control cabinet body 1. A vertical channel 2 is installed at the middle position of the top of the control cabinet body 1. A fan 3 is installed at the top of the vertical channel 2. A tee pipe 4 is installed below the vertical channel 2. Butterfly check valves 5 are installed at both ends of the tee pipe 4. When the fan 3 is not working, the butterfly check valves 5 are in a closed state to prevent dust from entering the control cabinet body 1 through the vertical channel 2. When the fan 3 works, the butterfly check valves 5 automatically open. Air intake windows 101 are opened on both sides below the control cabinet body 1. A window frame 6 is installed on the inner side surface of the air intake window 101. A filter slot 601 is opened in the middle of the window frame 6. A slide plate slot 602 is opened on one side of the window frame 6. A motor mounting plate 603 is arranged above the window frame 6. An outer filter plate 7 is inserted between the filter slot 601 and the inner side surface of the control cabinet body 1. A filter sponge 8 is arranged inside the slide plate slot 602. A dust scraping motor 9 is installed on one side of the motor mounting plate 603. An eccentric wheel 10 is installed at the rotating shaft of the dust scraping motor 9. An inner filter plate 11 is installed on the inner side surface of the window frame 6. When the fan 3 works, the air inside the control cabinet body 1 is pumped outwards. The outside air enters the control cabinet body 1 after being filtered by the filter sponge 8 through the air intake window 101. Through holes are opened on both the outer filter plate 7 and the inner filter plate 11. The outer filter plate 7 and the inner filter plate 11 respectively cover the inner and outer side surfaces of the filter sponge 8. The filter sponge 8 has good air permeability and can filter dust. A square slot hole 701 is arranged above the outer filter plate 7. The eccentric wheel 10 is inserted into the square slot hole 701. When the dust scraping motor 9 works, it drives the eccentric wheel 10 to rotate in the square slot hole 701, and then drives the outer filter plate 7 to move up and down. The amplitude of the up and down movement of the outer filter plate 7 is greater than the inner diameter of the opening of the outer filter plate 7, so as to scrape off the dust adsorbed on the outer surface of the filter sponge 8. The inner filter plate 11 is fixedly connected to the window frame 6 by screws. Unscrew the screws to remove the inner filter plate 11, and then the old filter sponge 8 can be taken off for replacement.

[0024] During use, only keep the intake window 101 and the vertical channel 2 as the two ventilation openings of the control cabinet 1, and the rest of the places are airtight and airtight. When the control cabinet 1 is in a premixed material assembly site with a lot of dust, there are two states. The first state is that the equipment is in the off state. At this time, the fan 3 is not working. Since the fan 3 is not working, there is no airflow from the inside to the outside in the vertical channel 2 and the tee pipe 4. At this time, the butterfly check valve 5 automatically closes without external force. Furthermore, the butterfly check valve 5 closes the channel connecting the air outlet inside and outside, so that the dust in the environment cannot enter the cabinet body from the heat dissipation air outlet. At this time, the air inlet of the heat dissipation is sealed by the filter sponge 8 and dust will not enter the control cabinet 1 either. The second state is that the equipment is in the on state. At this time, the fan 3 rotates to pump the air inside the control cabinet 1 outwards. The outside air enters the control cabinet 1 after being filtered by the filter sponge 8 through the intake window 101. Since the airflow is discharged from the heat dissipation air outlet from the inside to the outside, dust will not enter the cabinet body from the air outlet. At this time, with the filtering of the filter sponge 8 at the heat dissipation air inlet, dust cannot enter the cabinet body either but is blocked outside by the filter sponge 8. At the same time, the dust scraping motor 9 cooperates with the eccentric wheel 10 to drive the outer filter plate 7 to move up and down continuously to scrape the filter sponge 8, so that the dust adsorbed on the outer surface of the filter sponge 8 is automatically scraped off. Therefore, the filter sponge 8 does not need to be cleaned manually.

[0025] In summary, a butterfly check valve 5 is installed at the end of the pipeline at the heat dissipation air outlet of the on-site control cabinet for premixed material assembly. When the fan 3 is not working, the butterfly check valve 5 automatically closes the channel, thus preventing dust from entering the cabinet body from the heat dissipation air outlet. A filter sponge 8 capable of filtering dust is installed at the heat dissipation air inlet to prevent dust from being adsorbed inside the cabinet body. At the same time, the dust scraping motor 9 cooperates with the eccentric wheel 10 to drive the outer filter plate 7 to move up and down continuously to scrape the filter sponge 8, so that the dust adsorbed on the outer surface of the filter sponge 8 is automatically scraped off. Therefore, the filter sponge 8 does not need to be cleaned manually.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
