Description

Technical Field

[0001] This invention relates to the field of ventilation equipment technology, and more particularly to a hospital ventilation, air conditioning, circulation, and purification device. Background Technology

[0002] Hospitals have a high concentration of germs, and the environment is relatively enclosed. If germs and dust in the air cannot be effectively eliminated, it can easily lead to infection and cross-infection among patients and medical staff. Therefore, most hospital ventilation and air conditioning systems are equipped with purification devices.

[0003] Patent publication number CN114294749A discloses a circulating purification device for ventilation and air conditioning in a hospital building. The device includes a solid air scrubbing device and a filter device connected in series. The input end of the solid air scrubbing device is connected to the exhaust vent of the hospital building's ventilation area, and the output end of the filter device is connected to the air inlet of the same ventilation area. The solid air scrubbing device purifies primary exhaust air through solid particles and outputs secondary exhaust air to the filter device. The filter device filters the secondary exhaust air and then resupply clean air to the hospital building's ventilation area. This technical solution utilizes solid particle adsorption and fluidized bed principles to disinfect and filter the exhaust air from the hospital building before resupplying it for ventilation, reducing energy consumption and preventing the spread of pathogens from inside the hospital building to the outside.

[0004] When using the above-mentioned technical solution for hospital building ventilation, on the one hand, the air filtration device uses multi-layer filter screens and filter cartridges to filter dust, but some fine dust cannot be completely filtered, resulting in low dust removal efficiency; on the other hand, when the above-mentioned technical solution delivers outside air into the wards, there is no corresponding sterilization device, which poses certain safety hazards when ventilating the wards. Therefore, the above-mentioned technical solution needs further improvement. Summary of the Invention

[0005] In order to improve the sterilization and dust removal effects and add a filtration device for ventilation in the ward, this invention provides a hospital ventilation and air conditioning circulation purification device.

[0006] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0007] The hospital ventilation and air conditioning circulation purification device includes an equipment housing. An air intake hood is fixed inside the housing, and the housing has an air intake hole communicating with the hood. A transmission box is fixedly installed at the upper end of the air intake hood. Multiple air extraction components are installed inside the transmission box, with their bottoms extending into the air intake hood and connected to a sterilization component. An air supply component is installed on the inner wall of the transmission box, connected to a filter component. An exhaust pipe is connected to the filter component, with its top extending to the top of the equipment housing. A drive component is connected to the inner wall of the transmission box, connected to the multiple air extraction components, and also connected to the filter component.

[0008] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0009] ① In order to solve the problem of poor dust removal effect of existing purification devices, the present invention designs a filter component. The gas enters the spray box through the connecting box and the support pipe. The spray box disperses and delivers the gas to the dust removal screen. Through the transmission action of the power component, the dust removal screen can be rotated. At this time, multiple deflectors rotate, which can stir the liquid in the water tank, thereby filtering the dust in the gas and improving the dust removal effect of the purification device.

[0010] ② To address the lack of filter components in existing purification devices, this invention designs a sterilization mesh barrel and ultraviolet lamps. The sterilization mesh barrel is energized by the power supply of the support ring. The sterilization mesh barrel electrocutes and destroys the tissues of pathogens, killing them. The sterilization mesh barrel can rotate under the power transmission of the drive shaft, causing multiple ultraviolet lamps to move in a ring, which can perform a secondary electrocution on the gas entering the sterilization mesh barrel. At the same time, the ultraviolet lamps can adsorb pathogens, thus ensuring that the gas delivered to the ward does not contain pathogens.

[0011] ③ The purification device of the present invention, through the cooperation of a drive motor, drive components, linkage components, and power components, can drive the sterilization screen barrel of the sterilization component to rotate, drive the dust removal screen barrel of the filter component to rotate, and drive the suction blades of the extraction component to rotate. This saves the cost of using multiple drive motors, and the use of a single drive motor facilitates the control of the purification device's operation.

[0012] As a preferred embodiment, a further technical solution of the present invention is:

[0013] The air extraction assembly includes a drive shaft and suction blades; an installation plate is fixedly installed on the inner wall of the transmission box, and the drive shaft passes through the installation plate and is rotatably connected to the installation plate. The suction blades are fixedly sleeved on the upper end of the drive shaft. The drive shaft is connected to the drive assembly, and the bottom end of the drive shaft extends into the air intake hood and is connected to the sterilization assembly.

[0014] The drive shaft drives the air intake blades as an air extraction device. The drive shaft rotates under the drive component, which in turn drives the air intake blades to rotate, thereby pressurizing the gas in the air intake hood and delivering it to the filter component.

[0015] The sterilization assembly includes a support ring, a sterilization mesh barrel, and multiple ultraviolet lamps. The support ring is fixedly installed on the top inner wall of the air intake hood, and the sterilization mesh barrel is rotatably connected to the inner wall of the support ring. The bottom of the sterilization mesh barrel is rotatably connected to the bottom inner wall of the air intake hood. Multiple ultraviolet lamps are fixedly installed at equal intervals on the bottom inner wall of the sterilization mesh barrel. A battery is fixedly installed on the bottom inner wall of the sterilization mesh barrel. The battery is electrically connected to the multiple ultraviolet lamps, and the ultraviolet lamps are fixedly connected to the sterilization mesh barrel. The bottom end of the drive shaft extends into the sterilization mesh barrel and is fixedly connected to the bottom inner wall of the sterilization mesh barrel.

[0016] The sterilization mesh can be powered by the support ring. When the sterilization mesh is powered, it can kill the bacteria in the gas when it comes into contact with them. It can also kill any remaining bacteria that have entered the sterilization mesh using the ultraviolet light.

[0017] The gas delivery assembly includes multiple delivery pipes, a manifold, a conical pipe, and a gas delivery pipe. The multiple delivery pipes are fixedly installed at equal intervals on the top inner wall of the transmission box, and the top ends of the multiple delivery pipes extend to the top of the transmission box and are fixedly connected to the manifold. The manifold is connected to the conical pipe, the gas delivery pipe is fixedly connected to the conical pipe, and the gas delivery pipe is connected to the filter assembly.

[0018] Gas is delivered to the filter assembly through a delivery pipe, a collection box, a conical pipe, and a gas transmission pipe, improving gas transmission efficiency and facilitating gas collection and transmission.

[0019] Multiple fixing rods are fixedly installed at equal intervals on the bottom inner wall of the air intake hood. Scrapers are fixedly installed on the sides of the fixing rods, and the scrapers are in contact with the side wall of the corresponding sterilization mesh barrel.

[0020] The scraper removes pathogens from the side wall of the sterilization mesh barrel, causing them to fall to the bottom of the air intake hood, facilitating subsequent cleaning of the air intake hood and sterilization mesh barrel. At the same time, it ensures the normal operation of the sterilization mesh barrel, preventing an excessive amount of pathogens on the side wall of the sterilization mesh barrel from affecting the sterilization effect.

[0021] The drive assembly includes a drive motor, a fixed plate, a driving bevel gear, a driven bevel gear, a transmission rod, and a linkage component. The fixed plate is fixedly mounted on the side wall of the air intake shroud and is used to fix the drive motor. The output shaft of the drive motor passes through the fixed plate and is fixedly connected to the driving bevel gear. The driving bevel gear meshes with the driven bevel gear, and the driven bevel gear is fixedly sleeved on the transmission rod. One end of the transmission rod extends into the transmission box and is connected to the linkage component, and the other end of the transmission rod is connected to the filter assembly. The linkage component is connected to the inner wall of the transmission box and is connected to multiple transmission shafts.

[0022] By starting the drive motor to rotate the active bevel gear, the driven bevel gear can be driven to rotate under the meshing transmission action. When the drive rod rotates, it can drive the filter assembly and the linkage components to operate, thereby causing multiple drive shafts to rotate so as to perform air extraction.

[0023] The linkage component includes a drive shaft, two connecting blocks, a connecting bevel gear, a rotating bevel gear, and multiple worm gear components. The two connecting blocks are respectively fixedly installed on the front inner wall and the rear inner wall of the transmission box, and the drive shaft is rotatably connected to the two connecting blocks respectively. The rotating bevel gear is fixedly sleeved on the drive shaft and meshes with the connecting bevel gear. The connecting bevel gear is fixedly installed at one end of the transmission rod. Multiple worm gear components are all connected to the drive shaft and the worm gear components are connected to the corresponding transmission shafts.

[0024] When the connecting bevel gear rotates with the transmission rod, the drive shaft rotates under the meshing transmission action of the rotating bevel gear, and multiple transmission shafts rotate synchronously under the transmission action of multiple worm gear components.

[0025] The worm gear assembly includes a drive worm and a drive worm wheel; the drive worm is fixedly sleeved on the drive shaft, and the drive worm wheel is fixedly sleeved on the transmission shaft corresponding to the drive worm, and the drive worm and the drive worm wheel mesh with each other.

[0026] By coordinating the drive worm and the drive worm wheel, the drive worm wheel drives the corresponding transmission shaft to rotate, thereby enabling the intake blades to smoothly draw in air.

[0027] The filter assembly includes a water tank, power unit, connection box, support pipe, dust collection screen, spray box, and multiple baffles;

[0028] The water tank is fixed to the bottom inner wall of the equipment box. The lower end of the exhaust pipe is fixed through the top inner wall of the water tank and extends into the water tank. The transmission rod is rotatably connected to the front side of the water tank. The connecting box is fixed to the bottom inner wall of the water tank. The air supply pipe extends into the connecting box. The support pipe is fixedly installed on the top inner wall of the connecting box. The top end of the support pipe extends into the dust collector barrel and is rotatably connected to the bottom inner wall of the dust collector barrel. Multiple levers are installed on the inner wall of the dust collector barrel. The top end of the support pipe extends into the spray box and is fixedly connected to the bottom inner wall of the spray box. The spray box is located inside the dust collector barrel.

[0029] The power component is installed on the side wall of the water tank, the transmission rod is connected to the power component, and the rear side of the power component extends into the water tank. The power component is connected to the bottom of the dust removal screen barrel.

[0030] After the gas is transported to the connecting box through the gas transmission pipe, it can be transported to the spray box through the support pipe. The spray box then disperses the gas into the dust collection screen bucket, and the water in the water tank will soak into the dust collection screen bucket, thus dissolving the dust in the gas, washing the gas, and filtering the dust in the gas to achieve dust removal. The clean gas after dust removal is output through the exhaust pipe fixed on the water tank.

[0031] The power components include a rotating shaft, a transmission worm gear, a transmission worm, a transmission belt, a rotating rod, and a gear ring.

[0032] A rotating shaft is rotatably connected to the top front side of the water tank, with a transmission worm gear fixedly sleeved on the shaft and a transmission worm fixedly sleeved on the transmission rod. The transmission worm gear meshes with the transmission worm. A rotating rod is rotatably connected to the bottom front side of the water tank, with a transmission belt connected to both the rotating shaft and the rotating rod. The rear end of the rotating rod extends into the water tank and connects to a gear ring. The transmission belt includes two transmission wheels and a transmission belt. The two transmission wheels are fixedly sleeved on the rotating shaft and the rotating rod, respectively, and the transmission belt is sleeved on the two transmission wheels and connected to them. The gear ring includes a drive bevel gear and a bevel ring. The drive bevel gear is fixedly installed at the rear end of the rotating rod, and the bevel ring is fixedly installed at the bottom of the dust collector screen. The drive bevel gear meshes with the bevel ring.

[0033] The power components, through the meshing of the transmission worm and worm wheel, allow the shaft to rotate. The transmission belt then causes the rotating rod to rotate, and the meshing of the drive bevel gear and bevel ring causes the dust collector to rotate. This, in turn, causes multiple plates to move in a circular motion, stirring the liquid in the water tank, thereby reducing the liquid volume and completely filtering dust from the gas.

[0057] In this embodiment, the linkage component includes a drive shaft 18, two connecting blocks 17, a connecting bevel gear 20, a rotating bevel gear 21, and multiple worm gear components.

After the gas is transported to the connecting box 34 through the gas delivery pipe 7, it can be transported to the spray box 36 through the support pipe 35. The spray box 36 disperses the gas into the dust collector filter 40, and the water in the water tank 8 will soak into the dust collector filter 40, thus dissolving the dust in the gas, washing the gas, and filtering the dust in the gas to achieve dust removal. Specifically, cleaning fluid can be placed in the water tank 8 to facilitate better cleaning of dust impurities in the gas.

[0061] In this embodiment, the power component includes a rotating shaft 22, a transmission worm gear 23, a transmission worm 24, a transmission belt, a rotating rod 27, and a gear ring. The rotating shaft 22 is rotatably connected to the top front side of the water tank 8, and the transmission worm gear 23 is fixedly sleeved on the rotating shaft 22. The transmission worm 24 is fixedly sleeved on the transmission rod 10, and the transmission worm gear 23 meshes with the transmission worm 24. The rotating rod 27 is rotatably connected to the bottom front side of the water tank 8, and the transmission belt is connected to the rotating shaft 22 and the rotating rod 27 respectively. The rear end of the rotating rod 27 extends into the water tank 8 and is connected to the gear ring. The transmission belt includes two transmission pulleys 25 and a transmission belt 26. The two transmission pulleys 25 are fixedly sleeved on the rotating shaft 22 and the rotating rod 27 respectively, and the transmission belt 26 is sleeved on the two transmission pulleys 25 respectively, and is distributed between them. The transmission is not connected to the two transmission wheels 25; the gear ring includes a drive bevel gear 38 and a bevel ring 39; the drive bevel gear 38 is fixedly installed at the rear end of the rotating rod 27, and the bevel ring 39 is fixedly installed at the bottom of the dust collector 40, with the drive bevel gear 38 meshing with the bevel ring 39; under the meshing transmission action of the transmission worm 24 and the transmission worm wheel 23, the rotating shaft 22 rotates, and under the transmission action of the transmission belt 26, the rotating rod 27 rotates, and under the meshing transmission action of the drive bevel gear 38 and the bevel ring 39, the dust collector 40 rotates, thereby enabling multiple baffles 37 to perform circular motion, stirring the liquid in the water tank, thereby reducing the volume of liquid bubbles in the water tank, and completely filtering the dust in the gas.

[0062] The working principle of this embodiment is as follows: The air supply pipe of the air conditioning system is connected to the exhaust pipe 9 so that the gas can be delivered to the air conditioning system after processing. When it is necessary to supply gas to the air conditioning system, the drive motor 11 can be started to drive the active bevel gear 12 to rotate. At this time, under the meshing transmission action of the driven bevel gear 14, the transmission rod 10 can be driven to rotate. When the transmission rod 10 rotates, under the meshing transmission action of the connecting bevel gear 20 and the rotating bevel gear 21, the drive shaft 18 can be driven to rotate. When the drive shaft 18 rotates, the meshing of multiple drive worm gears 19 and multiple drive worm wheels 33... Under the action of transmission, multiple drive shafts 16 can be driven to rotate synchronously, which in turn drives multiple suction blades 28 to rotate, thus transporting the gas in the intake hood 2 to the transmission box 3; then the gas is transported to the collection box 5, and the conical pipe 6 and the gas delivery pipe 7 transport the gas to the connecting box 34, and the gas is distributed and transported to the dust removal screen 40 through the support pipe 35 and the spray box 36; when in use, cleaning fluid can be placed in the water tank 8, and the gas is washed with the cleaning fluid; the dust in the gas can be filtered, and the filtered gas can be transported upward and delivered to the air supply pipeline of the air conditioning system through the exhaust pipe 9, thus realizing gas purification.

[0063] After the gas inside the intake hood is drawn out by the intake blades, outside gas can enter the intake hood. When the gas passes through the sterilization mesh barrel, the sterilization mesh barrel itself can kill viruses in the air by utilizing its sterilization properties. Furthermore, the sterilization mesh barrel can rotate under the power transmission of the drive shaft, which causes multiple ultraviolet lamps to move in a ring. Under the action of the ultraviolet lamps moving in a ring, the gas entering the sterilization mesh barrel can be sterilized a second time, which can completely kill any remaining viruses in the gas. This ensures that the gas delivered to the ward does not contain viruses.

[0064] When the transmission rod 10 rotates, the meshing transmission action of the transmission worm 24 and the transmission worm wheel 23 drives the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, the transmission belt 26, under the transmission action of the transmission wheel 25, causes the rotating rod 27 to rotate. Under the meshing transmission action of the drive bevel gear 38 and the bevel ring 39, the dust removal screen 40 rotates. At this time, multiple baffles 37 can rotate, which can stir the liquid in the water tank, thereby filtering the dust in the gas. Stirring the liquid in motion can reduce the generation of bubbles, thereby thoroughly cleaning the gas and ensuring that the dust in the gas does not enter the ward, thus achieving the functions of sterilization and dust removal.

[0065] In summary, both the sterilization mesh and the dust removal mesh in this embodiment are driven by a drive assembly and a transmission assembly, which reduces the use of a drive motor and saves costs. The drive motor 11 pressurizes and delivers external gas to the air intake pipe of the air conditioning system in the ward. During the gas delivery, it can sterilize and remove dust, ensuring that the gas delivered to the ward does not contain germs or dust, thus providing a good air environment in the ward.
