Description

Technical Field

[0001] The utility model relates to the technical field of duct machines, in particular to an oil and gas filter screen for duct machines with dustproof function. Background Art

[0002] The full name of the duct air conditioner is a duct-type air conditioner. It uses air conditioners to connect air ducts to supply air to the room, solving the problem of wall-mounted and cabinet units being exposed to the outside and affecting the appearance. It is also low-cost, so it is widely popular. Air conditioning is an indispensable part of people's modern life. In hotel lobbies, private rooms, and especially hot pot restaurants, when diners are dining, the steam emitted from hot food contains a large number of oil molecules and water molecules floating in the air and is sucked in by the circulating air conditioner. When the water molecules are cooled, they will be condensed into condensed water and discharged. When the oil molecules encounter objects with a temperature lower than that of the oil molecules, they will be quickly adsorbed, and condense with the dust in the air to form hard putty, which will cover the heat exchanger to form a blockage. At this time, the air output of the air conditioner is reduced, bacteria will be deposited, odor will be generated, the air conditioner efficiency will decrease, energy consumption will increase, and the life of the air conditioner will be shortened. Therefore, the air conditioners used in restaurants and hot pot restaurants will be installed with multiple layers of overlapping interactive filters on the air inlet side of the air conditioner. When they encounter a metal filter with a temperature lower than that of the oil and gas, they will be adsorbed, and the dust in the air will also be adsorbed, which can ensure that the air conditioner fins are not blocked by oil.

[0003] The oil and gas adsorption filter of the existing duct air conditioner is usually directly installed on the outside of the air inlet. Figure 1 As shown), and the air outlet is open, so when the duct machine is not in use, external dust is easy to fall and adsorb on the filter surface, which can easily cause the filter to be blocked when the duct machine is in use, requiring frequent cleaning, increasing manual labor, and the oil and gas adsorption filter is installed by means of clips and screws, which is cumbersome to disassemble and assemble, resulting in low practicality.

[0028] A small servo electric cylinder 91 is fixedly installed on the inner bottom wall of the installation cavity 6, and one end of the piston rod of the small servo electric cylinder 91 is fixedly connected to a connecting block 92, and one end of the connecting block 92 is fixedly connected to a rack 93. The small servo electric cylinder 91 drives the rack 93 to move up and down through the cooperation of the connecting block 92. The tooth surfaces of the rack 93 are meshed with the tooth surfaces of multiple gears 9. The back of the dustproof frame 2 is fixedly connected to a symmetrically distributed plug plate 94, and a positioning hole 95 is provided on one side surface of the plug plate 94. The two side surfaces of the duct machine body 1 are fixedly connected to symmetrically distributed mounting blocks 96, and a slot 97 is provided on the front of the mounting block 96. The inner wall of the slot 97 is movably plugged with the outer surface of the plug plate 94, and the inner wall of the mounting block 96 is movably sleeved with a movable block 98. The plug plate 94 is limited by the plug-in connection with the slot 97, so as to perform a preliminary positioning of the dustproof frame 2.

[0029] A return spring 99 is fixedly connected to the surface of one side of the movable block 98, and one end of the return spring 99 is fixedly connected to the inner wall of one side of the mounting block 96. The return elastic force of the return spring 99 drives the movable block 98 to reset and move.

[0030] By setting up the flip device, when the duct machine body 1 is not in use, dust can be prevented from being adsorbed on the surface of the oil and gas filter 5 by flipping the rotating baffle 8, thereby extending the use time and reducing the number of cleaning times. The dustproof frame 2 and the oil and gas filter 5 are easy to disassemble and clean later, thereby improving the practicality.

[0031] Working principle: Step 1, when the air duct machine body 1 is working, the piston rod of the small servo electric cylinder 91 is started to extend, thereby driving the rack 93 to move upward through the connecting block 92, and the movement of the rack 93 drives the rotating rod 7 to rotate through the meshing gear 9, and the rotation of the rotating rod 7 drives the rotating baffle 8 to flip 90 degrees to open, thereby ensuring the circulation of the intake air, and the oil and gas in the air are adsorbed and filtered through the oil and gas filter 5;

[0032] Step 2: When the duct machine body 1 stops working, the piston rod of the small servo electric cylinder 91 retracts, and drives the rack 93 to move in the opposite direction through the connecting block 92, thereby driving the rotating rod 7 to rotate in the opposite direction through the meshing gear 9, so that the multiple rotating baffles 8 rotate in the opposite direction by 90 degrees, thereby cooperating with the air intake seal to prevent the falling dust from being adsorbed on the surface of the oil and gas filter 5;

[0033] Step three, when it is necessary to clean the dustproof frame 2 and the oil and gas filter 5, press the U-shaped pressure plate 913 to drive the movable block 98 to move through the travel block 911. The movement of the movable block 98 squeezes the return spring 99 and drives the positioning rod 912 to move to disengage from the positioning hole 95. At this time, the dustproof frame 2 can be pulled out of the slot 97 through the plug plate 94 to complete the disassembly. Due to the disassembly of the dustproof frame 2, the restriction of the filter frame 4 disappears. At this time, the filter frame 4 can be taken out from the installation slot 3 to complete the disassembly and cleaning of the oil and gas filter.
