Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, specifically to a spray-based dust removal, deodorization, cooling, and purification device for use in guesthouses. Background Technology

[0002] Generally speaking, in the daily operation of a homestay, the spray function of the spray purification equipment is needed to remove dust, degrade odors, and cool the environment in indoor and outdoor air, while also completing air purification treatment, thereby improving the quality of the homestay's living environment, enhancing the comfort of guests, and meeting the core operational needs of homestays for a clean and comfortable environment.

[0003] In practical applications, the water supply pipeline needs to switch between two modes: chemical dosing and no-dosing, depending on the treatment requirements. Regardless of the mode, the water flow in the pipeline must undergo subsequent impurity filtration. When the water flow velocity in the supply pipeline is high, the high-speed water flow will impact the filter element, causing excessive concentration of water flow in certain areas. This concentrated high-speed water flow will directly act on localized areas of the filter element, resulting in uneven stress on the filter element. Impurities in the water can easily accumulate rapidly in these areas, leading to localized clogging of the filter element. Furthermore, when switching the water supply pipeline to chemical dosing mode... In the flow mode, due to the high water flow rate and the filtering and interception effect of the filter element, undissolved chemical components in the solution are easily intercepted by the filter element and cannot smoothly pass through the filter element into the spray pipe with the water flow. This results in the chemical not being sprayed evenly to the target treatment area, and the chemical cannot fully exert its deodorizing and purifying effects. Based on this, the present invention purposefully provides a spray dust removal, deodorization, cooling and purification device for homestays that can avoid the problem of local clogging of the filter element caused by concentrated water flow, avoid the interception of undissolved chemical components in the solution by the filter screen during chemical dosing, and improve the stability of equipment operation. Summary of the Invention

A third valve is installed on the connecting pipe, and the outlet of the connecting pipe is connected to a buffer pipe. The outlet of the medicine pipe extends into the buffer pipe. The pipe wall has a through hole, and a slider is slidably installed inside the medicine pipe. The slider is connected to the medicine pipe by a spring. The preload of the spring causes the slider to block the through hole. A transmission rod is rotatably installed on the slider. A turbine blade is coaxially fixedly installed on the end of the transmission rod facing the dosing device. The outlet of the buffer pipe is connected in sequence to the pipeline filter, water softener, and UV sterilizer to the water tank. The water pump is connected to the water tank through a pumping pipe. The output end of the water pump is connected to an outlet pipe. The outlet pipe is connected to a branch pipe. The branch pipe is connected to multiple branch pipes, and each branch pipe is connected to multiple nozzles.

[0006] As a further embodiment of the present invention: a microporous plate is fixedly installed inside the buffer tube, and one end of the medicine tube extending into the buffer tube faces the microporous plate, and the microporous plate is provided with a plurality of circumferentially arranged micropores.

[0007] As a further aspect of the present invention: the transmission rod passes through the medicine pipe and is slidably connected to the medicine pipe; a stirring rod is fixedly installed at one end of the transmission rod facing the microporous plate; when the slider blocks the through hole, the stirring rod moves away from the microporous plate; when the slider moves away from the through hole, the stirring rod moves closer to the microporous plate.

[0008] As a further aspect of the present invention: each branch pipe is connected to a pressure relief pipe at the end away from the shunt pipe, and a pressure relief solenoid valve is provided at the connection point between each branch pipe and the pressure relief pipe.

[0009] As a further aspect of the present invention: a drain pipe is connected to the bottom of the water tank, a drain valve is provided on the drain pipe, a pressure relief pipe is connected to the drain pipe, and the connection point between the pressure relief pipe and the drain pipe is located below the drain valve.

[0010] As a further aspect of the present invention: a first solenoid valve is provided on the water outlet pipe, an air inlet pipe is connected between the first solenoid valve and the branch pipe on the water outlet pipe, the air inlet pipe is connected to an external air supply component, an air inlet solenoid valve is provided on the air inlet pipe, and a second solenoid valve is provided at the connection point between each branch pipe and the branch pipe.

[0011] As a further aspect of the present invention: a first water level sensor and a second water level sensor are fixedly installed inside the water tank, wherein the horizontal height of the first water level sensor is lower than the horizontal height of the second water level sensor.

[0012] As a further aspect of the present invention: an ultraviolet sterilizer is fixedly installed inside the water tank, and a breather valve is fixedly installed on the top of the water tank.

[0013] The beneficial effects of this invention are: 1. In this invention, when it is necessary to add medicine, the water flow drives the dosing device to draw medicine from the medicine tank. The water pressure of the mixed water flow overcomes the spring preload, pushes the slider to slide and opens the through hole, so that the mixed medium flows evenly into the buffer pipe. At the same time, the water flow drives the turbine blade to rotate, and drives the slider to rotate synchronously through the transmission rod, disturbing the water flow and slowing down the water speed. In this way, the slider buffers the medicine to avoid impacting the pipeline filter, and the turbine blade strengthens the mixing, which completely solves the problems of medicine sedimentation and clumping, pipeline blockage and poor spraying effect caused by incomplete mixing. 2. In this invention, an innovative linkage structure is formed by fixing a microporous plate with micropores inside the buffer tube and setting a stirring rod at the end of the transmission rod. When water flows through the microporous plate, the micropores play a secondary buffering role, preventing the water flow from directly impacting the filter screen of the pipeline filter, preventing the filter screen from being damaged and the filtration effect from decreasing. The stirring rod moves synchronously with the transmission rod to the vicinity of the microporous plate and rotates at high speed with the turbine blade, which not only further enhances the uniformity of the mixing of medicine and water, but also scrapes the surface of the microporous plate, cleans the residual impurities and clumps of medicine in the micropores, realizes the self-cleaning of the microporous plate, and solves the problems of micropore blockage and poor water flow. 3. In this invention, after the spraying operation is completed, the pressure relief solenoid valve is opened, and the residual liquid in the pipeline is collected through the pressure relief pipe and discharged through the drain pipe. This prevents the residual liquid from deteriorating, breeding bacteria, crystallizing and clogging the pipeline. After the residual liquid is discharged, the first solenoid valve is closed and the air inlet solenoid valve is opened. Nitrogen gas is used to purge the pipeline to thoroughly remove residual moisture and solve the problems of low temperature freezing and bacterial growth. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-5 As shown, this invention is a spray-based dust removal, deodorization, cooling, and purification device for guesthouses, comprising: The machine body 1 contains a water tank 11. The machine body 1 is fixedly equipped with an inlet pipe 2, a dosing device 3, a medicine tank 4, a pipeline filter 8, a water softener 9, a UV sterilizer 10, and a water pump 12. The inlet pipe 2 is connected to the inlet of the dosing device 3 and is also connected to a water passage pipe 7. A first valve 301 is installed at the inlet of the dosing device 3, and a second valve 302 is installed at the outlet of the dosing device 3. The outlet of the dosing device 3 is connected to a medicine pipe 6, and the dosing device 3 is connected to the medicine tank 4. A third valve 701 is installed on the water passage pipe 7, and the outlet of the water passage pipe 7 is connected to a buffer pipe 5. The outlet of the medicine pipe 6 extends into the buffer pipe 5, and the wall of the medicine pipe 6 has openings... A through hole 26 is provided. A slider 27 is slidably installed inside the medicine pipe 6. The slider 27 is connected to the medicine pipe 6 by a spring 30. The preload of the spring 30 causes the slider 27 to block the through hole 26. A transmission rod 31 is rotatably installed on the slider 27. A turbine blade 29 is coaxially fixedly installed on one end of the transmission rod 31 facing the dosing device 3. The outlet of the buffer pipe 5 is connected to the pipeline filter 8, the water softener 9, and the UV sterilizer 10 in sequence to the water tank 11. The water pump 12 is connected to the water tank 11 through the water pump pipe 13. The output end of the water pump 12 is connected to the outlet pipe 14. The outlet pipe 14 is connected to the branch pipe 15. The branch pipe 15 is connected to multiple branch pipes 16. Each branch pipe 16 is connected to multiple nozzles 17.

[0019] The working principle of this invention is as follows: The core is to achieve water filtration, chemical mixing, and spray purification through the coordinated operation of various components. This solves problems such as poor dust removal, deodorization, and cooling effects in guesthouse environments, as well as incomplete chemical mixing, easy pipe blockage, and easy equipment damage. When preparing the spray medium, water enters the equipment through the inlet pipe 2, and medium delivery is achieved in two working conditions: When no chemicals are needed, the operator closes the first valve 301 and the second valve 302, while simultaneously opening the third valve 701. At this time, the water flow is diverted from the inlet pipe 2 to the flow pipe 7, and then flows directly into the buffer pipe 5. Subsequently, it enters the pipeline filter 8, the water softener 9, and the UV sterilizer 10 in sequence. After the pipeline filter 8 intercepts impurities in the water, the water softener 9 reduces the hardness of the water, and the UV sterilizer 10 kills microorganisms in the water, it finally flows into the water tank 11 for temporary storage. This process can avoid pipeline interference caused by the dosing device 3 being idle when there are no chemicals. At the same time, through multi-stage filtration and sterilization, it solves the problem of impurities, hard water scale, and microorganisms in the water causing nozzle 17 to become clogged and the spray water quality to be poor, thus affecting the dust removal and deodorization effect.

[0020] When adding chemicals is required: The operator opens the first valve 301 and the second valve 302, while simultaneously closing the third valve 701. Water flows from the inlet pipe 2 into the dosing device 3. The dosing device 3 is a Venturi dosing device. Utilizing the Venturi effect, the dosing device 3 draws the deodorizing and disinfecting chemicals from the chemical tank 4 into its interior. After initial mixing with the water, the mixture is delivered through the chemical pipe 6 to the inlet of the buffer pipe 5. At this time, the water pressure of the mixed water acts on the slider 27, overcoming the preload of the spring 30, and pushes the slider 27 to slide along the inner wall of the chemical pipe 6, opening the through hole 26 that was originally blocked by the slider 27. The mixed water then flows through the through hole 26 evenly. The mixed water flows evenly into the buffer pipe 5. At the same time, the flowing mixed water drives the turbine blade 29 to rotate at high speed, thereby disturbing the water flow in the buffer pipe 5 and slowing down the water speed. The sliding of the slider 27 buffers the chemical solution, preventing the chemical solution from impacting the pipeline filter 8 instantly. The water flow disturbance driven by the turbine blade 29 further enhances the uniformity of the mixing of the chemical solution and water, solving the problems of chemical solution sedimentation and clumping, incomplete mixing, which leads to the subsequent interception of the filter screen of the pipeline filter 8, the clogging of the nozzle 17, and the deterioration of the spray disinfection and deodorization effect. The uniformly mixed medium is then processed by the pipeline filter 8, the water softener 9, and the UV sterilizer 10 before being stored in the water tank 11. During the spraying operation: the water pump 12 is started, and the water pump 12 draws the treated spraying medium from the water tank 11 through the water suction pipe 13. After pressurizing the medium, it is delivered to the distribution pipe 15 through the water outlet pipe 14. The distribution pipe 15 evenly distributes the medium to multiple branch pipes 16, and finally atomizes and sprays it out through multiple nozzles 17 on each branch pipe 16. The atomized medium comes into contact with dust and odor molecules in the air of the guesthouse, achieving the effects of dust removal, deodorization and cooling. The arrangement of multiple branch pipes 16 and nozzles 17 can expand the spraying range and solve the problems of incomplete spraying coverage and uneven purification effect when the guesthouse space is large.

[0021] like Figures 1-3 As shown, in a preferred embodiment of the present invention, a microporous plate 25 is fixedly installed inside the buffer tube 5, and one end of the medicine tube 6 extending into the buffer tube 5 faces the microporous plate 25. The microporous plate 25 has a plurality of circumferentially arranged micropores.

[0022] Specifically, the transmission rod 31 passes through the medicine pipe 6 and is slidably connected to the medicine pipe 6. A stirring rod 28 is fixedly installed at one end of the transmission rod 31 facing the microporous plate 25. When the slider 27 blocks the through hole 26, the stirring rod 28 moves away from the microporous plate 25. When the slider 27 moves away from the through hole 26, the stirring rod 28 moves closer to the microporous plate 25.

[0023] In practical application, regardless of whether chemicals are added, the water flowing into the buffer pipe 5 must pass through multiple micropores on the microporous plate 25. The microporous plate 25 can provide secondary buffering for the water flow, slowing down the water flow speed and preventing the water flow from directly impacting the filter screen inside the pipeline filter 8. This solves the problem of excessive water flow impact causing filter screen damage, reduced filtration effect, and frequent filter screen replacement. When chemicals need to be added and the slider 27 is pushed by water pressure, the slider 27 drives the transmission rod 31 to move axially synchronously, thus enabling the transmission... The stirring rod 28 at the end of the rod 31 is close to the microporous plate 25; at the same time, the turbine blade 29 drives the transmission rod 31 to rotate, and the transmission rod 31 drives the stirring rod 28 to rotate at high speed in front of the microporous plate 25. On the one hand, this further disturbs the water flow, enhances the uniformity of mixing of the medicine and water, and avoids the residue and clumping of the medicine. On the other hand, the stirring rod 28 can scrape the surface of the microporous plate 25 during rotation, cleaning the impurities or clumps of medicine remaining in the micropores. This solves the problem of micropore blockage and poor water flow in the microporous plate 25, which in turn affects the efficiency of media treatment.

[0024] like Figures 1-5 As shown, in a preferred embodiment of the present invention, each branch pipe 16 is connected to a pressure relief pipe 18 at the end away from the diversion pipe 15, and a pressure relief solenoid valve 1602 is provided at the connection between each branch pipe 16 and the pressure relief pipe 18.

[0025] Specifically, the bottom of the water tank 11 is connected to a drain pipe 19, a drain valve 1901 is provided on the drain pipe 19, the pressure relief pipe 18 is connected to the drain pipe 19, and the connection between the pressure relief pipe 18 and the drain pipe 19 is located below the drain valve 1901.

[0026] In practical application, after the spraying disinfection or cooling operation is completed, the water pump 12 is turned off, and the pressure relief solenoid valves 1602 on all branch pipes 16 are opened. The water and chemicals remaining in the branch pipes 16, the diversion pipes 15, and the outlet pipes 14 flow into the pressure relief pipes 18 under gravity. After being collected in the pressure relief pipes 18, they are transported to the drain pipes 19 and finally discharged outwards. This process solves the problems of residual media deterioration and bacterial growth in the pipeline, or residual chemicals crystallizing and clogging the pipelines and nozzles 17, which affect the use of subsequent equipment and the spraying effect. When the equipment is not in operation for a long time, the intelligent control system judges the cumulative working time logic and opens the drain valve 1901 periodically. The impurities and aging media settled in the water tank 11 are discharged through the drain pipe 19, realizing the periodic sewage discharge of the water tank 11 and avoiding the accumulation of impurities that affect the quality of the spray water. Since the pressure relief pipe 18 is connected to the drain pipe 19 and the connection point is located below the drain valve 1901, the residual liquid in the pipe and the sewage from the water tank 11 can be discharged through the same drain pipe 19, realizing the unified discharge outlet and solving the problems of scattered discharge outlets, inconvenient cleaning, and easy secondary pollution of the homestay environment.

[0027] like Figures 1-5 As shown, in a preferred embodiment of the present invention, a first solenoid valve 1401 is provided on the water outlet pipe 14, and an air inlet pipe 20 is connected between the first solenoid valve 1401 and the diversion pipe 15 on the water outlet pipe 14. The air inlet pipe 20 is connected to an external air supply component, and an air inlet solenoid valve 2001 is provided on the air inlet pipe 20. A second solenoid valve 1601 is provided at the connection between each branch pipe 16 and the diversion pipe 15.

[0028] In practical application, after the residual liquid in the pipeline is discharged, the first solenoid valve 1401 is closed, followed by the pressure relief solenoid valve 1602. The air intake solenoid valve 2001 and the second solenoid valves 1601 on all branch pipes 16 are opened. The external air supply component delivers nitrogen gas to the water outlet pipe 14 through the air intake pipe 20. The nitrogen gas flows through the diversion pipe 15 and each branch pipe 16 in sequence, and finally exits from the nozzle 17 and the pressure relief pipe 18. The pressure relief solenoid valve 1602 can be opened again to discharge the nitrogen gas. The purging effect of nitrogen gas can thoroughly remove the residual water and residual liquid in the pipeline, solving the problems of residual water in the pipeline breeding bacteria and causing spray medium contamination, as well as residual water freezing and clogging the pipeline and damaging the equipment in low-temperature environments. This further improves the cleanliness of the pipeline and extends the service life of the equipment.

[0029] like Figures 1-5 As shown, in a preferred embodiment of the present invention, a first water level sensor 21 and a second water level sensor 22 are fixedly installed inside the water tank 11, and the horizontal height of the first water level sensor 21 is lower than the horizontal height of the second water level sensor 22.

[0030] In practical application, the first water level sensor 21 serves as a low water level warning. When the water level in the water tank 11 drops below the horizontal height of the first water level sensor 21, the first water level sensor 21 sends a signal to the intelligent control system. The intelligent control system immediately issues a water shortage alarm and shuts down the water pump 12 to stop the spraying operation. This solves the problem of the water pump 12 running dry and burning when there is a water shortage in the water tank 11, which leads to damage to the water pump 12 motor and equipment failure. It also protects the water pump 12.

[0031] The second water level sensor 22 plays a role in water level monitoring and automatic water replenishment control. When the water level in the water tank 11 drops below the horizontal height of the second water level sensor 22, the second water level sensor 22 sends a signal to the intelligent control system. The intelligent control system opens the control valve of the water inlet pipe 2 to replenish water into the water tank 11 through the water inlet pipe 2. When the water level in the water tank 11 rises above the horizontal height of the second water level sensor 22, the intelligent control system closes the control valve of the water inlet pipe 2 and stops water replenishment. This process realizes automatic control of the water level in the water tank 11, which solves the problems of interruption of sprinkler operation due to untimely manual water replenishment, or water tank 11 overflowing due to excessive water replenishment, resulting in water waste and damage to the homestay environment.

[0032] like Figures 1-5 As shown, in a preferred embodiment of the present invention, an ultraviolet sterilizer 23 is fixedly installed inside the water tank 11, and a breather valve 24 is fixedly installed on the top of the water tank 11.

[0033] In practical application, the ultraviolet sterilizer 23 works continuously, releasing high-energy photons to kill microorganisms in the spray medium inside the water tank 11. This solves the problem that microorganisms grow in the spray medium when it is stored in the water tank 11 for a long time, which leads to poor water quality, reduced deodorization and sterilization effect, and even pollution of the guesthouse environment. This further improves the safety and effectiveness of spray purification.

[0034] The water tank 11 is a closed structure. When the water inlet pipe 2 replenishes water into the water tank 11, the air inside the water tank 11 is compressed, the pressure increases, and the breather valve 24 automatically opens to expel the excess air. When the water pump 12 draws the medium from the water tank 11, a negative pressure is formed inside the water tank 11, and the breather valve 24 automatically opens to draw in external air, maintaining the atmospheric pressure balance inside and outside the water tank 11. This process solves the problems of poor water replenishment caused by the closed water tank 11, increased suction resistance of the water pump 12, and even damage to the water tank 11 due to abnormal pressure, ensuring the stable operation of the equipment.

[0035] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
