Description

Technical Field

[0001] The invention belongs to the technical field of air purification, in particular to a purification device for HVAC ventilation. Background Art

[0002] HVAC is a device with heating, ventilation and air conditioning functions. It adjusts and controls the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. With the advancement of the times, most air conditioners have air purification functions, and the air inlet of the air conditioner is generally equipped with a filter to prevent dust from falling into the air, so as to ensure the quality of the air blown out by the air conditioner.

[0003] When using HVAC for air purification in harsh environments such as factories, the HVAC is working continuously and the amount of dust adsorbed is much greater than that in ordinary homes. A large amount of dust will quickly accumulate on the filter, thereby reducing the filtering effect of the air conditioner and causing the air conditioner's working function to decline. Therefore, the air conditioner working machine needs to be improved. Summary of the invention

The support partition separates the middle part of the filter box shell from the upper and lower sides, providing space for air circulation and preventing the gas inhaled by the left air conditioner from entering parts outside the center of the filter box shell.

[0007] Furthermore, the outer surface of the independent motor is fixedly connected to the inner cavity of the supporting partition through a through-cut groove, the inner wall of the deflection plate is mutually squeezed with the outer surface of the rotary filter belt through a cleaning brush, and the outer surface of the connecting rotating rod is rotationally connected to the inner wall of the supporting partition through a through-cut groove. The inner wall of the rotary filter belt is rotationally connected to the outer surface of the transfer torsion rod, and the number of the transfer torsion rods is four. The outer surface of the torque motor is fixedly connected to the inner wall of the filter box shell, and the outer surface of the rotary filter belt is slidably connected to the inner cavity of the supporting partition through a through-cut groove. The outer surface of the rotary filter belt is slidably connected to the inner wall of the limit clamp, and the outer surface of the limit clamp is fixedly connected to the inner wall of the filter box shell, and the number of the limit clamp is two. Suction plates are symmetrically arranged on the upper and lower sides of the inner cavity of the filter box shell, and an internal cleaning component is arranged at the axis of the inner wall of the filter box shell.

[0008] Furthermore, the shock rod component includes a control plate, the front side of the control plate is fixedly connected with a guide slide rail, and control slide rods are symmetrically arranged on the left and right sides of the guide slide rail, the end of the control slide rod away from the control plate is fixedly connected with a clamping claw, and the inner wall of the clamping claw is fixedly connected with a vertical slide plate, and the top of the vertical slide plate is fixedly connected with a blower shell, and the blower shell can blow impurities on the inner side of the rotating filter belt to the position between the supporting partitions through the nozzle facing the side of the rotating filter belt, and absorb them through the internal cleaning components on the front and rear sides, the number of the control plates is eight, and the outer surface of the control plate is fixedly connected to the inner wall of the filter box shell, the outer surface of the control slide rod is slidably connected to the inner wall of the guide slide rail, the bottom end of the vertical slide plate is slidably connected to the inner wall of the supporting partition, and the inner wall of the blower shell and the outer surface of the transfer torsion bar are squeezed against each other.

[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 upper and lower sides of the inner cavity of the main adsorber are fixedly connected with built-in through pipes through through-holes, and the end of the built-in through pipe away from the main adsorber is fixedly connected to a transfer box, and an elastic sliding shell is fixedly connected to the middle of the inner cavity of the transfer box, and a cleaning rod is rotatably connected to the end of the inner cavity of the elastic sliding shell away from the transfer box.

[0010] Furthermore, a sliding rod shell is fixedly connected to the inner wall of the transfer box, and vertical push rods are evenly arranged on the side of the inner cavity of the sliding rod shell close to the cleaning rotating rod, and a built-in impact plate is fixedly connected to the end of the vertical push rod away from the sliding rod shell. The outer surface of the cleaning rotating rod and the inner wall of the rotating filter belt are squeezed against each other, and the sliding rod shell can drive the built-in impact plate to slide up and down through the vertical push rod, thereby pushing the cleaning rotating rod and the elastic sliding shell to move.

[0011] Furthermore, the outer surface of the sliding rod shell is fixedly connected to the middle of the inner wall of the transfer box, the end of the built-in through pipe away from the main adsorber extends to the interior of the transfer box, the end of the built-in through pipe close to the main adsorber extends to the outside of the supporting partition through the through opening, and the outer surface of the main adsorber is plugged into the middle of the inner cavity of the filter box shell.

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

[0013] 1. The device can pre-purify the air entering the air conditioner. Through the filtering effect of the rotary filter belt mesh, the dust and impurities entering the air conditioner can be intercepted in advance, thereby ensuring that the air conditioner is not prone to dust ingress problems. In order to ensure a good air intake effect of the air conditioner and avoid the air inlet being blocked and affecting its function, the device can change the actual filtering position of the rotary filter belt by rotating the rotary filter belt, so that the device maintains a good ventilation effect.

[0014] 2. When the device switches and twists the rotary filter belt, the part where the rotary filter belt enters the filter box shell will be purified, thereby unblocking its mesh holes and restoring the filtering capacity of this part. Therefore, the device has a self-cleaning function and can continuously perform air purification for a long time. Moreover, when cleaning the main adsorber and suction plate that always adsorb impurities, they can be taken out from the outside for replacement, thereby making the actual maintenance operation easier and optimizing the actual use experience.

[0015] 3. Since the transfer torsion bar will certainly rotate in close contact with the rotary filter belt, the air blast housing can blow away the dust facing the transfer torsion bar through its air outlet, thereby cleaning the transfer torsion bar and preventing the transfer torsion bar from slipping. In order to prevent the rotary filter belt from loosening during filtering, the control slide bars on both sides of the same control panel can clamp the air blast housing so that the air blast housing fixes the transfer torsion bar, preventing the transfer torsion bar from deflecting due to the rotary filter belt, causing the rotary filter belt to loosen.

[0016] 4. During operation, the sliding rod shell will reciprocate and push the built-in impact plate to impact the cleaning rotating rod. At this time, the elastic sliding shell will expand and contract accordingly and move adaptively to adjust the distance between the top of the elastic sliding shell and the inner side of the rotary filter belt, thereby changing the actual adsorption effect. When the cleaning rotating rod impacts the stretched rotary filter belt, the rotary filter belt will shake, making it easier to remove the impurities adsorbed inside and reduce the residual amount of impurities inside the rotary filter belt.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a purification device for HVAC ventilation, comprising a purification body 1, both left and right sides of the purification body 1 are fixedly connected with external connection pipes 2, and both front and rear sides of the purification body 1 are fixedly connected to the wall through fixed racks 3, the external connection pipe 2 on the right side is an air intake pipe, and the external connection pipe 2 on the left side is a ventilation pipe for inputting air conditioning;

[0027] The purification body 1 includes a filter box shell 11, and a torque motor 12 is symmetrically arranged on the front and rear sides of the inner wall of the filter box shell 11, and a transfer torsion bar 13 is fixedly connected to the outer surface of the output shaft of the torque motor 12, and a shock rod component 6 is symmetrically arranged on the front and rear sides of the outer surface of the transfer torsion bar 13, and a rotary filter belt 16 is rotatably connected to the middle part of the outer surface of the transfer torsion bar 13, and a support partition 15 is symmetrically arranged on the upper and lower sides of the inner wall of the filter box shell 11, and a limited clamping plate 14 is symmetrically arranged on the front and rear sides of the middle of the inner wall of the filter box shell 11, and an external cleaning component 5 is symmetrically arranged on both sides of the support partition 15, and there are four transfer torsion bars 13, which are arranged around the device to open the rotary filter belt 16 that surrounds the whole circle to form a rectangular structure, and the air is filtered through the filter hole part of the rotary filter belt 16 in the vertical direction;

[0028] The left and right sides of the inner cavity of the support partition 15 are symmetrically provided with through grooves. The external cleaning component 5 includes an independent motor 51. The outer surface of the output shaft of the independent motor 51 is fixedly connected to a connecting rod 52. The lower part of the outer surface of the connecting rod 52 is fixedly connected to a deflection plate 53. Cleaning brushes 54 are evenly arranged on the inner wall of the deflection plate 53 close to the rotating filter belt 16. The support partition 15 separates the middle part of the filter box shell 11 from the upper and lower sides, providing space for air circulation and preventing the gas inhaled by the left air conditioner from entering the part outside the center of the filter box shell 11.

[0029] The outer surface of the independent motor 51 is fixedly connected to the inner cavity of the support partition 15 through the through-cut groove, the inner wall of the deflection plate 53 is mutually squeezed with the outer surface of the rotary filter belt 16 through the cleaning brush 54, and the outer surface of the connecting rod 52 is rotationally connected to the inner wall of the support partition 15 through the through-cut groove. The inner wall of the rotary filter belt 16 is rotationally connected to the outer surface of the transfer torsion bar 13, and the number of the transfer torsion bars 13 is four. The outer surface of the torque motor 12 is fixedly connected to the inner wall of the filter box shell 11, and the outer surface of the rotary filter belt 16 is slidably connected to the inner cavity of the support partition 15 through the through-cut groove. The outer surface of the rotary filter belt 16 is slidably connected to the inner wall of the limit clamp 14, and the outer surface of the limit clamp 14 is fixedly connected to the inner wall of the filter box shell 11, and the number of the limit clamp 14 is two. Suction plates 17 are symmetrically arranged on the upper and lower sides of the inner cavity of the filter box shell 11, and an inner cleaning component 4 is arranged at the axis of the inner wall of the filter box shell 11.

[0030] When using the device, the right side external connection pipe 2 is directly connected to the suction head on the outer surface, the left side external connection pipe 2 is directly connected to the air inlet of the air conditioner, and then the device is fixed to the wall through the fixing frame rod 3 to complete the preparation work.

[0031] When the air conditioner is working, the gas flows from right to left, and then the air flows through the middle of the filter box shell 11. The air will perform simple air filtering through the mesh in the middle of the rotary filter belt 16, thereby filtering out dust and impurities in the air. After working for a period of time, the torque motor 12 located on the inner wall of the filter box shell 11 begins to twist the transfer torsion bar 13, so that the transfer torsion bar 13 drives the rotary filter belt 16 to rotate through rolling friction, thereby switching the actual filtering position of the rotary filter belt 16, and then performing filtering work.

[0032] During the sliding process of the rotary filter belt 16, the rotary filter belt 16 enters the position of the side groove of the supporting partition 15 and performs preliminary filtering through the external cleaning component 5. At this time, the independent motor 51 rotates the deflection plate 53 through the connecting rotating rod 52, so that the deflection plate 53 deflects close to one side of the rotary filter belt 16, and the dust and impurities on the outer surface of the rotary filter belt 16 are swept away by the relative friction between the cleaning brush 54 and the outer surface of the rotary filter belt 16.

[0033] After the rotary filter belt 16 has filtered for a period of time, the part switched to the inside of the filter box shell 11 will rotate to the upper and lower positions. At this time, the outer side of the rotary filter belt 16 is reversely attracted by the suction plates 17 on the upper and lower sides, and the inner side of the rotary filter belt 16 is adsorbed by the internal cleaning component 4 in the middle, thereby realizing the cleaning of the rotary filter belt 16.

[0034] Example 2, please refer to Figure 1-Figure 7The present invention provides a technical solution: on the basis of the first embodiment, the shock rod component 6 includes a control plate 61, the front of the control plate 61 is fixedly connected with a guide rail 62, and the left and right sides of the guide rail 62 are symmetrically provided with control slide bars 63, and the end of the control slide bar 63 away from the control plate 61 is fixedly connected with a clamping claw 64, and the inner wall of the clamping claw 64 is fixedly connected with a vertical slide plate 65, and the top of the vertical slide plate 65 is fixedly connected with a blast shell 66, and the blast shell 66 can blow the impurities on the inner side of the rotary filter belt 16 to the position between the supporting partitions 15 through the nozzle on the side facing the rotary filter belt 16, and absorb them through the internal cleaning components 4 on the front and rear sides.

[0035] There are eight control panels 61, and the outer surface of the control panel 61 is fixedly connected to the inner wall of the filter box shell 11, the outer surface of the control slide rod 63 is slidably connected to the inner wall of the guide slide rail 62, the bottom end of the vertical slide plate 65 is slidably connected to the inner wall of the support partition 15, and the inner wall of the blower housing 66 and the outer surface of the transfer torsion bar 13 are squeezed against each other.

[0036] The internal cleaning component 4 includes a main adsorber 41, and adsorption grooves 42 are evenly opened in the middle of the outer surface of the main adsorber 41. The upper and lower sides of the inner cavity of the main adsorber 41 are fixedly connected with built-in through pipes 43 through through-holes. The end of the built-in through pipe 43 away from the main adsorber 41 is fixedly connected to a transfer box 44, and an elastic sliding shell 45 is fixedly connected to the middle of the inner cavity of the transfer box 44. The end of the inner cavity of the elastic sliding shell 45 away from the transfer box 44 is rotatably connected to a cleaning rotating rod 46. The main adsorber 41 has two through-holes for adsorbing impurities, one is the adsorption grooves 42 evenly opened in the middle, which are used to clean impurities between the supporting partitions 15, and the other is a straight through-hole on the upper and lower sides, and adsorption and drainage work is performed through the built-in through pipe 43.

[0037] The inner wall of the transfer box 44 is fixedly connected to a slide rod shell 47, and vertical push rods are evenly arranged on one side of the inner cavity of the slide rod shell 47 close to the cleaning rotating rod 46, and a built-in impact plate 48 is fixedly connected to the end of the vertical push rod away from the slide rod shell 47. The outer surface of the cleaning rotating rod 46 and the inner wall of the rotating filter belt 16 are squeezed against each other, and the slide rod shell 47 can drive the built-in impact plate 48 to slide up and down through the vertical push rod, thereby pushing the cleaning rotating rod 46 and the elastic sliding shell 45 to move.

[0038] The outer surface of the slide rod shell 47 is fixedly connected to the middle of the inner wall of the adapter box 44, and the end of the built-in through pipe 43 away from the main adsorber 41 extends to the interior of the adapter box 44, and the end of the built-in through pipe 43 close to the main adsorber 41 extends to the outside of the supporting partition 15 through the through opening, and the outer surface of the main adsorber 41 is plugged into the middle of the inner cavity of the filter box shell 11.

[0039] Since the transfer torsion bar 13 will definitely rotate in contact with the rotary filter belt 16, when the shock rod component 6 is working, its control plate 61 synchronously pulls the control slide bars 63 on both sides to move in the direction of contact with the transfer torsion bar 13 and then resets. At this time, the vertical slide plate 65 drives the air blowing sleeve 66 to reciprocate and hit the outer surface of the transfer torsion bar 13, so that the transfer torsion bar 13 continues to twist the rotary filter belt 16 while keeping rotating, and then the air blowing sleeve 66 blows away the dust facing the transfer torsion bar 13 through its blowing port, thereby completing the cleaning of the transfer torsion bar 13 and preventing the transfer torsion bar 13 from slipping.

[0040] The main adsorber 41 absorbs the dust blown off by the blowing sleeve 66 and the dust swept off by the cleaning brush 54 through the adsorption groove 42 in the middle. At the same time, the main adsorber 41 also adsorbs the mesh on the inner side of the rotary filter belt 16 that needs to be cleaned through the built-in through-tube 43. At this time, the cleaning rotating rod 46 sweeps away the impurities on the inner side of the rotary filter belt 16, and then the adsorption effect of the elastic sliding shell 45 can clean the rotary filter belt 16 and the cleaning rotating rod 46.

[0041] During operation, the sliding rod shell 47 will reciprocate and push the built-in impact plate 48 to impact the cleaning rotating rod 46. At this time, the elastic sliding shell 45 will expand and contract accordingly and move adaptively, thereby adjusting the distance between the top of the elastic sliding shell 45 and the inner side of the rotary filter belt 16, changing the actual adsorption effect. When the cleaning rotating rod 46 impacts the stretched rotary filter belt 16, the rotary filter belt 16 will shake, making it easier to remove impurities adsorbed inside.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
