Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air purification, and particularly relates to a purification device for heating ventilation air conditioning ventilation. BACKGROUND

[0002] Heating ventilation air conditioning is a device with the functions of heating, ventilation and air conditioning, which adjusts and controls the parameters such as temperature, humidity and flow rate of the ambient air in a building or structure. With the progress of the times, most air conditioners have air purification function. In order to prevent dust from falling into the air inlet of the indoor unit of the air conditioner, a filter screen is generally arranged to ensure the air quality blown out by the air conditioner.

[0003] When the heating ventilation air conditioning is used for air purification in harsh environments such as workshops, since the heating ventilation air conditioning works continuously and the amount of dust adsorbed is much larger than that in general household places, a large amount of dust is quickly accumulated in the filter screen part, thereby reducing the filtering effect of the air conditioner and causing the working function of the air conditioner to decrease. Therefore, the working machine of the air conditioner needs to be improved. SUMMARY

Suction plates are symmetrically provided on the upper and lower sides of the inner cavity of the filter box shell, and an internal cleaning component is provided at the axis of the inner wall of the filter box shell.

[0008] The top end of the vertical slide is fixedly connected to the air filter housing, and the air filter housing is fixedly provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip.

[0009] Furthermore, the internal cleaning component includes a main adsorber, and adsorption grooves are evenly opened in the middle of the outer surface of the main adsorber.

The main adsorber has two through-holes for adsorbing impurities, one is the adsorption grooves evenly opened in the middle, which is used to clean impurities between the supporting partitions, and the other is a straight through-hole on the upper and lower sides, which performs adsorption and drainage through the built-in through pipes.

[0010] Further, the inner wall of the adapter box is fixedly connected with a slide rod shell, vertical push rods are uniformly arranged on the inner cavity of the slide rod shell close to the side of the cleaning rotating rod, and an inner built-in baffle is fixedly connected to the end of the vertical push rod away from the slide rod shell, the outer surface of the cleaning rotating rod is in mutual extrusion with the inner wall of the rotary filter belt, and the slide rod shell can drive the built-in baffle to slide up and down, so as to push the cleaning rotating rod and the elastic slide shell to move.

[0012] The beneficial effects of the present application are as follows:

[0013] 1.

[0014] 2. When the device switches and twists the rotary filter belt, the part of the rotary filter belt entering the filter box shell will be cleaned, so as to dredge the mesh holes and restore the filtering capacity of this part, so that the device has a self-cleaning function and can continuously perform long-time air purification work, and the main adsorber and the suction plate for adsorbing impurities can be taken out from the outside for replacement work, so that the actual maintenance operation is more convenient and the actual use experience is optimized.

[0015] 3.

In order to prevent the rotary filter belt from loosening during the filtering work, the control slide rods on both sides of the same control board can clamp the air blowing sleeve shell, so that the air blowing sleeve shell fixes the adapter twist rod, prevents the adapter twist rod from being deflected due to the rotary filter belt, and causes the problem of loosening of the rotary filter belt.

[0016] 4. In operation, the slide rod shell reciprocally pushes the built-in impact plate to impact the cleaning rotating rod, at this time the elastic slide shell will make corresponding expansion and contraction changes, adaptively move, so as to adjust the distance between the top of the elastic slide shell and the inner side of the rotary filter belt, change the actual adsorption effect, when the cleaning rotating rod impacts the expanded rotary filter belt, the rotary filter belt will vibrate, so that it is easier to remove the impurities adsorbed inside, and the residual amount of impurities inside the rotary filter belt is reduced.

The adapter torsion rod 13 is four, arranged around the device, and the whole rotary filter belt 16 is expanded to form a structure similar to a rectangle, and the air is filtered through the vertical filter hole part of the rotary filter belt 16;

[0028] Through holes are symmetrically arranged on the left and right sides of the inner cavity of the support partition 15, the outer cleaning part 5 comprises an independent motor 51, a connecting rotating rod 52 is fixedly connected to the outer surface of the output shaft of the independent motor 51, a deflection rotating plate 53 is fixedly connected to the lower part of the outer surface of the connecting rotating rod 52, cleaning brushes 54 are uniformly arranged on the inner wall of the deflection rotating plate 53 close to the rotary filter belt 16, the support partition 15 separates the middle part and the upper and lower sides of the filter box shell 11, provides a space for the flow of air, and prevents the gas sucked by the air conditioner on the left side from entering the parts outside the center of the filter box shell 11.

[0031] When the air conditioner works, the gas flows from right to left, then the air flows through the position in the middle of the filter box shell 11, the air is simply filtered through the mesh holes in the middle of the rotary filter belt 16, so that the dust impurities in the air are filtered out, after working for a period of time, the torque motor 12 on the inner wall of the filter box shell 11 starts to twist the rotating connecting torsion rod 13, so that the rotating connecting torsion rod 13 drives the rotary filter belt 16 to rotate through the rolling friction, so as to switch the actual filtering position of the rotary filter belt 16, and then the filtering work is performed.

[0034] Example 2, please refer to Figures 1-7The application provides a technical scheme: on the basis of example one, the shock rod part 6 comprises a control plate 61, the front surface of the control plate 61 is fixedly connected with a guide sliding rail 62, the left side and the right side of the guide sliding rail 62 are symmetrically provided with control sliding rods 63, one end of the control sliding rod 63 away from the control plate 61 is fixedly connected with a clamping jaw 64, and the inner wall of the clamping jaw 64 is fixedly connected with a vertical sliding plate 65, the top end of the vertical sliding plate 65 is fixedly connected with a blowing sleeve 66, and the blowing sleeve 66 can blow the impurities on the inner side of the rotary filter belt 16 to the position between the support partition plates 15 through the nozzle opposite to one side of the rotary filter belt 16, and the impurities are adsorbed and removed by the front and rear inner cleaning parts 4.

[0035] The number of the control plates 61 is eight, and the outer surfaces of the control plates 61 are fixedly connected with the inner wall of the filter box shell 11, the outer surfaces of the control sliding rods 63 are slidably connected with the inner wall of the guide sliding rail 62, the bottom end of the vertical sliding plate 65 is slidably connected with the inner wall of the support partition plate 15, and the inner wall of the blowing sleeve 66 is in mutual extrusion with the outer surface of the adapter torsion rod 13.

[0036] The inner cleaning part 4 comprises a main adsorber 41, the outer surface of the main adsorber 41 is uniformly provided with an adsorption slot 42 in the middle, the upper side and the lower side of the inner cavity of the main adsorber 41 are fixedly connected with built-in through pipes 43 through penetrating holes, one end of the built-in through pipe 43 away from the main adsorber 41 is fixedly connected with an adapter box 44, the middle of the inner cavity of the adapter box 44 is fixedly connected with an elastic sliding shell 45, the inner cavity of the elastic sliding shell 45 is rotatably connected with a cleaning rotary rod 46 at one end away from the adapter box 44, the main adsorber 41 has two adsorption impurity through ports, one is the adsorption slot 42 uniformly provided in the middle, for cleaning the impurities between the support partition plates 15, and the other is the straight through port on the upper side and the lower side, for adsorbing and draining through the built-in through pipe 43.
