Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an energy-saving air purification exhaust fan. Background Technology

[0002] In some production environments, large amounts of air pollutants such as dust and particulate matter are generated. To maintain air quality in the working environment and protect the health of personnel and the safety of equipment, exhaust fans are usually installed for forced ventilation and dust removal. Currently, one common dust removal method is to install spray equipment in the exhaust duct. By spraying water mist onto the dust-laden airflow, the collision, interception, and agglomeration of water droplets with dust particles cause the dust to be wetted, increased in weight, and then settled with the water flow, thereby achieving the purpose of purifying the air.

[0003] However, this traditional spray dust suppression method has a significant drawback: the water after spraying mixes with the dust to form wastewater, which is usually discharged directly or needs to be collected and purified before it can be reused. In practical applications, due to the large size and high cost of the treatment system or site limitations, the wastewater is often not effectively recycled and is instead discharged directly. This leads to two main problems: first, direct discharge of wastewater may cause secondary pollution to the environment; second, and more critically, in order to maintain continuous spray dust suppression, the system needs to constantly replenish a large amount of clean water from an external water source.

[0004] In water-rich areas, this problem is not as prominent. However, in certain specific application scenarios, such as arid and water-scarce regions, ocean-going vessels, mobile work platforms, or field operations lacking a stable water supply network, the supply of clean water is inherently very tight or extremely costly. The large consumption of clean water by traditional exhaust fans not only significantly increases operating costs, but more seriously, if the external water supply is insufficient, the sprinkler system will malfunction, causing the exhaust fan's dust suppression function to fail. This leads to a rapid deterioration of the air quality in the entire working environment, seriously affecting production and personnel safety. Summary of the Invention

[0005] This invention provides an energy-saving air purification exhaust fan, which can solve the following problems existing in the prior art:

[0006] Existing dust suppression spray systems for exhaust fans require a large amount of clean water, making them unusable in environments with insufficient water resources.

[0013] Preferably, a water collection tray is provided at the bottom of the condenser, and the water collection tray is connected to the processing module through a return water pipe.

[0014] Preferably, the drain pipe and the return pipe are connected to the circulation end via a connecting pipe. The processing module includes a processing box arranged on one side of the air box. The end of the circulation end slides against the top wall of the processing box. The processing box is symmetrically provided with a first processing chamber and a second processing chamber. The first processing chamber is provided with a first water inlet, and the second processing chamber is provided with a second water inlet.

[0015] The bottom of the air box is also fixedly equipped with a translation module, which is used to drive the processing box to reciprocate in the horizontal direction.

[0016] Preferably, the bottom of the first processing chamber is connected to the first processing cylinder, the bottom of the second processing chamber is connected to the second processing cylinder, the first mud discharge roller is rotatably arranged inside the first processing cylinder, the second mud discharge roller is rotatably arranged inside the second processing cylinder, and the roller walls of the two mud discharge rollers are slidably attached to the cylinder wall of the processing cylinder respectively.

[0017] The first mud discharge roller has a first mud storage trough, the second mud discharge roller has a second mud storage trough, and the processing module also includes a rotating part, which is used to drive the first mud discharge roller and the second mud discharge roller to rotate respectively.

[0018] Preferably, the first sludge discharge roller is fixedly connected to a first gear disposed on the outside of the first processing cylinder, and the second sludge discharge roller is fixedly connected to a second gear disposed on the outside of the second processing cylinder;

[0019] The rotating part includes a rack that meshes synchronously with the first gear and the second gear.

[0020] Preferably, water guide grooves are also provided on the roller walls of the first and second mud discharge rollers;

[0021] The end of the water guide channel is connected to a drainage pipe, which extends to the outside of the treatment cylinder.

[0022] Preferably, the bottom of the air box is provided with a water storage tank, and a water inlet groove is opened on the side wall of the water storage tank, and the ends of the two sets of drainage pipes are respectively slidably embedded in the water inlet groove;

[0023] The bottom of both sets of processing cylinders is also equipped with a collection box.

[0024] Preferably, the processing box is provided with a material box for storing flocculant. The bottom of the material box is symmetrically provided with a first discharge cylinder and a second discharge cylinder. A first discharge roller is rotatably arranged in the first discharge cylinder, and a second discharge roller is rotatably arranged in the second discharge cylinder. The discharge rollers on both sides slide against the cylinder wall of the discharge cylinder. A first discharge groove is opened on the first discharge roller, and a second discharge groove is opened on the second discharge roller.

[0025] The bottom of the discharge cylinders on both sides is connected to the processing chamber through the feeding port opened on the processing box, and the discharge rollers on both sides are respectively connected to the gear transmission through the synchronous belt mechanism.

[0026] This invention provides an energy-saving air purification exhaust fan, which has the following beneficial effects:

[0027] 1) After spraying the air, the wastewater from the spraying can be temporarily collected in a water storage box. Then, the wastewater in the water storage box can be purified by the processing module so that it can be used directly in the future, thus achieving the effect of water recycling. Compared with the existing technology that directly discharges wastewater, the present invention improves water utilization, is more environmentally friendly, and can still achieve normal air purification even when applied in water-scarce environments.

[0028] 2) This invention sets up two sets of treatment chambers. The treatment tank can be driven to move horizontally by a translation module, so that the inlet of any one set of treatment chambers is connected to the circulation end. This allows sewage in the drain pipe and return pipe to be discharged from the circulation end to the inlet and finally transported into the treatment chamber. When the amount of sewage in the treatment chamber reaches a preset amount, this embodiment can drive the treatment tank to move to one side by a translation module and perform purification treatment. During this process, the inlet of the other set of treatment chambers can be switched to connect with the circulation end to store water again. The purified water and sludge in the treatment chamber are discharged independently. The treatment chambers are then switched again by the translation module. This process is repeated to achieve continuous water collection and water purification treatment. The two sets of treatment chambers are independent of each other to ensure the efficiency of water treatment.

[0029] 3) In this invention, when the second inlet is connected to the circulation end, the second sludge storage tank is in a state away from the second treatment chamber, and the first sludge storage tank is facing the first treatment chamber. At this time, the mud and water in the first treatment chamber are separated, and the sludge accumulates in the first sludge storage tank. When the amount of sewage in the second treatment chamber reaches a preset value, the translation module drives the treatment box to translate so that the second inlet is separated from the circulation end. At this time, the rotating part can drive the second sludge discharge roller to rotate so that the second sludge storage tank rotates to communicate with the second treatment chamber for subsequent sludge storage. At the same time, the first inlet moves towards the circulation end. During this process, the rotating part drives the first sludge discharge roller to rotate so that the first sludge storage tank rotates to a state away from the first treatment chamber. The sludge accumulated in the first sludge storage tank can be discharged from the bottom opening of the first treatment cylinder under the action of gravity. This process is repeated to achieve the effect of mud and water separation. Attached Figure Description

[0042] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0043] Example 1

[0044] like Figures 1 to 4 As shown in the figure, an energy-saving air purifying exhaust fan provided by this embodiment of the invention includes a wind box 1. The wind box 1 has an air inlet 101 on one side and an air outlet 105 on the other side. Specifically, in this embodiment, when purifying the air, the wind box 1 is placed in the corresponding position, and the air can enter the wind box 1 through the air inlet 101 and then be discharged through the air outlet 105. In addition, this embodiment does not limit the specific setting position of the air inlet 101 and the air outlet 105 on the wind box 1. They can be set on the top wall of the wind box 1 or on the side wall of the wind box 1, depending on the actual application scenario.

[0045] In this embodiment, a fan 701 is provided inside the air box 1. An air inlet 704 is opened on one side of the fan 701, and the other side is connected to the air outlet 105 through the exhaust channel 703. It should be noted that after the outside air enters the air box 1 through the air inlet 101, it can be transported to the air outlet 105 and discharged to the outside of the air box 1 through the air inlet 704 and the exhaust channel 703 under the action of the fan 701, thereby achieving the effect of air supply.

[0046] The fan 701 has an impeller 702 rotatably mounted inside it. The impeller 702 is fixed to the output end of the servo motor 7, which is fixed inside the wind box 1, through a transmission mechanism. It can be explained that when the fan 701 is turned on, the servo motor 7 can be started, and the servo motor 7 can drive the impeller 702 inside the fan 701 to rotate through the transmission mechanism.

[0047] As one embodiment of this invention, a spray chamber 503 is provided inside the air box 1 on the side facing the air inlet 101. A spray box 5 is fixedly arranged on the top of the spray chamber 503, and several sets of spray nozzles 502 are evenly arranged at the bottom of the spray box 5. The spray box 5 is connected to the water supply module. Specifically, when outside air is delivered into the air box 1 through the air inlet 101, outside pure water can be delivered into the spray box 5 through the water supply module and finally sprayed out through the spray nozzles 502 to perform dust suppression treatment on the air entering the air box 1.

[0048] The spray chamber 503 has a water storage box 504 at its bottom for receiving spray water. The bottom of the water storage box 504 is connected to the processing module through a drain pipe 505. The processing module is used to purify the wastewater in the water storage box 504. It can be noted that in this embodiment, after spraying the air, the spray wastewater can be temporarily collected in the water storage box 504. Then, the wastewater in the water storage box 504 can be purified by the processing module so that it can be used directly afterward, achieving the effect of water recycling. Compared with the prior art where wastewater is directly discharged, this embodiment improves water utilization, is more environmentally friendly, and can still achieve normal air purification even when applied in water-scarce environments.

[0049] In addition, to facilitate maintenance inside the air box 1, in this embodiment, a first maintenance port 102 is opened on the side of the air box 1 facing the spray chamber 503, and a second maintenance port 103 is opened on the side facing the fan 701. Both the first maintenance port 102 and the second maintenance port 103 are rotatably equipped with sealing doors 104. Specifically, in the initial state, the sealing doors 104 on both sides are closed to the first maintenance port 102 and the second maintenance port 103, respectively. When it is necessary to inspect or maintain the spray chamber 503 or the fan 701, the sealing doors 104 can be opened.

[0050] Example 2

[0051] Based on Example 1, please refer to Figures 1-3 To further improve the air purification effect, an electret filter 604 is also provided inside the air box 1. Specifically, electret filtration is a technology that uses a persistent electrostatic charge to efficiently adsorb particulate matter by giving the filter material fibers a permanent electrostatic charge. It utilizes the principle of electrostatic adsorption, which greatly improves the filtration efficiency while maintaining low air resistance. Based on this, in this embodiment, after removing large dust impurities from the air through spraying technology, small air impurities are then treated by the electret filter 604 to fully improve the air purification effect.

[0052] It should also be noted that after the air passes through the spray device to reduce dust, the air humidity is relatively high. In actual application, water molecules in the air can affect the charge of the electret filter 604. In order to avoid the air humidity being too high and affecting the normal filtration of the electret filter 604, in this embodiment, a condenser 6 is also provided on the side of the electret filter 604 facing the air inlet 101. Specifically, by setting the condenser 6, the moisture in the air can be condensed and liquefied in advance, thereby improving the dryness of the air. In this embodiment, the specific model and structure of the condenser 6 are not limited, as long as they meet the actual application requirements.

[0053] To collect the liquid water condensed by condenser 6, a water collection tray 601 is installed at the bottom of condenser 6. The water collection tray 601 is connected to the processing module through a return water pipe 602. It can be explained that after the air is sprayed, some small dust particles are wrapped by water molecules. Therefore, they can be condensed and liquefied during the process of passing through condenser 6, so that the condensed liquid water contains dust impurities. The condensate is first discharged into the water collection tray 601 for temporary storage, and then discharged into the processing module through the return water pipe 602 for water purification treatment, so as to facilitate subsequent recycling.

[0054] As one implementation method of this embodiment, please refer to Figures 2-5 as well as Figures 7-9The drain pipe 505 and the return pipe 602 are connected to the circulation end 603 via connecting pipes. The processing module includes a processing box 2 disposed on one side of the air box 1. The end of the circulation end 603 slides against the top wall of the processing box 2. The processing box 2 is symmetrically provided with a first processing chamber 310 and a second processing chamber 311. The first processing chamber 310 is provided with a first water inlet 303, and the second processing chamber 311 is provided with a second water inlet 304. A translation module 401 is also fixedly disposed at the bottom of the air box 1. The translation module 401 is used to drive the processing box 2 to reciprocate in the horizontal direction. It can be noted that, in this embodiment, by setting two sets of processing chambers, the processing box 2 can be driven to move horizontally by the translation module 401, so that either The inlet of the treatment chamber is connected to the circulation end 603, so that the sewage in the drain pipe 505 and the return pipe 602 can be discharged from the circulation end 603 to the inlet and finally transported into the treatment chamber. When the amount of sewage in the treatment chamber reaches the preset amount, this embodiment can drive the treatment box 2 to move to one side through the translation module 401 and perform purification treatment. During this process, the inlet of the other treatment chamber can be switched to be connected to the circulation end 603 at the same time to store water again. The purified water and sludge in the treatment chamber are discharged independently. The treatment chamber is switched again through the translation module 401. This process is repeated to achieve continuous water collection and water purification treatment. The two treatment chambers are independent of each other to ensure the efficiency of water treatment.

[0055] Furthermore, the translation module 401 in this embodiment can adopt a synchronous belt drive mechanism or a screw and nut drive mechanism. This embodiment does not limit this to any particular type, as long as it meets the actual application requirements.

[0056] It should also be noted that when the translation module 401 moves the processing chamber that has reached the predetermined storage capacity to one side, the sewage in the processing chamber that has been moved to one side will achieve mud-water stratification under the action of settling, so as to facilitate subsequent mud-water separation.

[0057] In this embodiment, the bottom of the first processing chamber 310 is connected to the first processing cylinder 207, and the bottom of the second processing chamber 311 is connected to the second processing cylinder 202. A first sludge discharge roller 210 is rotatably arranged inside the first processing cylinder 207, and a second sludge discharge roller 211 is rotatably arranged inside the second processing cylinder 202. The roller walls of the two sludge discharge rollers slide against the cylinder wall of the processing cylinder, respectively. A first sludge storage groove 212 is provided on the first sludge discharge roller 210, and a second sludge storage groove 213 is provided on the second sludge discharge roller 211. The processing module also includes a rotating part, which is used to drive the first sludge discharge roller 210 and the second sludge discharge roller 211 to rotate, respectively. For example, when the second water inlet 304 is connected to the circulation end 603, the second sludge storage groove 213 is in a state away from the second processing chamber 311, while the first sludge storage groove 212 is in a state facing the first processing chamber 310. At this time, the mud and water in the first treatment chamber 310 are separated, and the sludge accumulates in the first sludge storage tank 212. When the amount of sewage in the second treatment chamber 311 reaches the preset value, the translation module 401 drives the treatment box 2 to translate so that the second inlet 304 is separated from the circulation end 603. At this time, the second sludge discharge roller 211 can be driven to rotate by the rotating part so that the second sludge storage tank 213 rotates to communicate with the second treatment chamber 311 for subsequent sludge storage. At the same time, the first inlet 303 moves towards the circulation end 603. During this process, the rotating part drives the first sludge discharge roller 210 to rotate so that the first sludge storage tank 212 rotates to a state away from the first treatment chamber 310. The sludge accumulated in the first sludge storage tank 212 can be discharged from the bottom opening of the first treatment cylinder 207 under the action of gravity. By repeating this process, the mud and water separation effect can be achieved.

[0058] Please refer to Figures 1-2 as well as Figures 4-6 The first mud-discharging roller 210 is fixedly connected to the first gear 203 disposed on the outside of the first processing cylinder 207, and the second mud-discharging roller 211 is fixedly connected to the second gear 206 disposed on the outside of the second processing cylinder 202. The rotating part includes a rack 205 that meshes synchronously with the first gear 203 and the second gear 206. It can be explained that when the translation module 401 drives the processing box 2 to translate, it can synchronously drive the first gear 203 and the second gear 206 to translate. During the movement, the first gear 203 and the second gear 206 can drive the mud-discharging roller to rotate by meshing with the rack 205. In this embodiment, there is no need to set up other servo drive devices to adjust the rotation of the first gear 203 and the second gear 206 separately. Based on the translation of the processing box 2, the effect of adjusting the rotation of the first gear 203 and the second gear 206 can be automatically realized, thereby realizing the effect of adjusting the mud-discharging rollers on both sides for mud storage and mud discharge. This not only improves the synchronization and stability, but also reduces control and lowers costs.

[0059] In this embodiment, during the process of discharging sludge, the sludge discharge roller simultaneously discharges the stratified water from the treatment chamber; see reference [link to relevant documentation]. Figures 7-10 Water guide grooves 209 are also provided on the roller walls of the first row of mud rollers 210 and the second row of mud rollers 211. The end of the water guide groove 209 is connected to the drainage pipe 208, which extends to the outside of the treatment cylinder. It can be explained that when the mud storage tank is in a state of communication with the treatment chamber, the water guide groove 209 is in a state of close and closed with the cylinder wall of the treatment cylinder. During the process of the mud discharge roller driving the mud storage tank to rotate from the side of the treatment chamber to the side away from the treatment chamber, the water guide groove 209 rotates to connect with the treatment chamber. The water in the treatment chamber can be discharged along the water guide groove 209 and the drainage pipe 208 for subsequent collection and recycling.

[0060] To collect the treated water and sludge separately, please refer to [link / reference]. Figures 1-2 , Figure 5 as well as Figure 10 The bottom of the air box 1 is equipped with a water storage tank 4, and a water inlet groove 402 is opened on the side wall of the water storage tank 4. The ends of two sets of drainage pipes 208 are slidably embedded in the water inlet groove 402. The bottom of the two sets of treatment cylinders is also equipped with a collection box 201. It can be explained that when the purified water is discharged from the drainage pipe 208, it can be discharged into the water storage tank 4 through the water inlet groove 402 for collection. The sludge in the sludge storage tank can be discharged into the collection box 201 for collection at the same time.

[0061] It should also be noted that the rack 205 is fixed to one side of the water storage tank 4. The water delivery module includes a circulation pump. In this embodiment, the water storage tank 4 can be connected to the circulation pipe 501 through the circulation pump. The circulation pipe 501 is connected to the spray box 5. After the purified water is discharged to the water storage tank 4, it is then transported to the spray box 5 for spraying through the circulation pump and the circulation pipe 501, so as to achieve the effect of recycling.

[0062] Furthermore, since the water in the sludge is also discharged into the collection tank 201 during the sewage separation process, the total water volume is reduced. In this embodiment, a monitor can be installed in the water storage tank 4. When the water volume in the water storage tank 4 is lower than the preset value, the water pump will replenish it accordingly. The water content in the sludge discharged in this embodiment is relatively low. Compared with the prior art, this embodiment still greatly reduces water consumption and achieves the effect of water saving.

[0063] To improve the purification effect, the treatment box 2 is equipped with a material box 3 for storing flocculant. A first discharge cylinder 301 and a second discharge cylinder 302 are symmetrically fixed at the bottom of the material box 3. A first discharge roller 305 is rotatably arranged inside the first discharge cylinder 301, and a second discharge roller 306 is rotatably arranged inside the second discharge cylinder 302. The two discharge rollers slide against the cylinder walls. A first discharge groove 307 is formed on the first discharge roller 305, and a second discharge groove 308 is formed on the second discharge roller 306. The bottom is connected to the treatment chamber through the feeding port 309 opened on the treatment box 2. The discharge rollers on both sides are respectively connected to the gear transmission through the synchronous belt mechanism 204. It can be explained that when the discharge chute faces the material box 3, the flocculant in the material box 3 can be discharged into the discharge chute. In this embodiment, when the gear drives the sludge discharge roller to rotate, it can synchronously drive the discharge roller to rotate through the synchronous belt mechanism 204, thereby discharging the flocculant into the treatment chamber, further improving the subsequent flocculation and sedimentation effect and efficiency of sewage, and improving the sewage purification quality.

[0064] In this embodiment, during the process of adding flocculant into the treatment chamber, it is also important to note that before the discharge trough rotates to connect with the feeding port 309, the water guide trough 209 has already rotated to a state of sealing and fitting with the treatment cylinder, so as to avoid the phenomenon that the flocculant is directly discharged from the water guide trough 209 after being added to the treatment chamber.

[0065] A method for operating an energy-saving air purification exhaust fan includes the following steps:

[0066] Please see Figures 1-3 S1, outside air is delivered to the air box 1 through the air inlet 101;

[0067] S2. The water supply module delivers pure water from the outside to the spray box 5, and finally sprays it out through the spray end 502 to treat the dust in the air entering the air box 1.

[0068] S3. After the spraying treatment, the wastewater from the spraying can be temporarily collected in the water storage box 504.

[0069] S4. The processing module purifies the wastewater in the water storage box 504.

[0070] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
