Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco auxiliary equipment, specifically relating to a high-efficiency and energy-saving ventilation device for the tobacco industry. Background Technology

[0002] In the tobacco industry, heating, ventilation and air conditioning (HVAC) systems are a key component, primarily used to control temperature, humidity and air quality in the production environment to ensure the quality of tobacco products and production efficiency. The tobacco industry's demand for high-efficiency and energy-saving ventilation devices is not only to reduce energy consumption and improve production efficiency, but also to meet increasingly stringent environmental regulations and sustainable development requirements.

[0003] Because traditional ventilation devices may lack partition designs, airflow is prone to turbulence, resulting in low fan efficiency, scattered airflow, and poor ventilation. Single or limited filtration levels cannot perform multi-stage deep filtration of air, making it difficult to provide a clean air environment and thus compromising the quality of tobacco products. Therefore, those skilled in the art provide a high-efficiency and energy-saving ventilation device for the tobacco industry to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and energy-saving ventilation device for the tobacco industry, so as to solve the shortcomings of the above-mentioned background technology.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] This application provides a high-efficiency and energy-saving ventilation device for the tobacco industry. By installing partitions inside the air inlet and outlet frames, airflow is separated, resulting in more orderly airflow and preventing turbulence. This also improves fan efficiency and concentrates airflow through the filter and housing. Bolt-fixed filters facilitate cleaning and replacement, simplifying operation, improving maintenance efficiency, and reducing costs. The device employs a four-box horizontal arrangement, each containing different filter materials, including a sieve, activated carbon, absorbent cotton, and a filter membrane, providing multi-stage filtration for the air. This provides a cleaner air environment for the tobacco industry, helping to ensure the quality of tobacco products. Multiple heaters heat water to generate steam, which adsorbs, dissolves, or reacts with impurities and harmful substances in the air, purifying the air.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high-efficiency and energy-saving ventilation device for the tobacco industry includes a housing. An air inlet frame is located at the lower center of one side wall of the housing, and an air outlet frame is located at the lower center of another side wall of the housing. Both the air inlet frame and the air outlet frame have an air inlet structure inside. A baffle is located at the center of the interior of the housing. A filter structure is located at the center of the upper surface of the baffle on one side of the housing. A purification structure is located at the center of the lower inner wall of the housing on one side. A cavity is located at the lower end of the housing on the other side. Three sets of sterilization lamps are arranged horizontally at the center of the front and rear inner walls of the cavity.

[0009] The above technical solution utilizes internal partitions in the air inlet and outlet frames to separate airflow, making airflow more orderly and preventing turbulence. This also improves fan efficiency, allowing airflow to be more concentrated through the filter and housing. Bolt-fixed filters facilitate cleaning and replacement, simplifying operation, improving maintenance efficiency, and reducing costs. The design employs four horizontally arranged boxes, each containing different filter materials including a sieve, activated carbon, absorbent cotton, and a filter membrane, providing multi-stage filtration for the air. This provides a cleaner air environment for the tobacco industry, helping to ensure the quality of tobacco products. Multiple heaters heat water to generate steam, which adsorbs, dissolves, or reacts with impurities and harmful substances in the air, purifying the air.

[0010] Furthermore, the two air inlet structures include two filters, eight bolts, four fans, and two partition plates. The two filters are respectively located at the center of one side wall of the air inlet frame and the air outlet frame. The eight bolts are arranged in groups of four, and the two groups of bolts are arranged in a rectangular pattern on one side wall of the two filters. The two partition plates are respectively located at the center of the air inlet frame and the air outlet frame. The four fans are respectively located at the front and rear of the center of the air inlet frame and the air outlet frame.

[0011] With the above technical solution, the four fans inside the air inlet and exhaust frames start up and generate airflow. At the air inlet frame, the fans draw outside air into the housing, and at the exhaust frame, the fans expel the air from the housing. The air is initially filtered by the filter screen as it passes through the air inlet and exhaust frames, blocking larger particles such as dust and fibers. The partition plate separates the airflow, making the airflow more orderly and avoiding airflow turbulence. At the same time, the partition plate may also help improve the working efficiency of the fans, making the airflow generated by the fans pass through the filter screen and the inside of the housing more concentratedly. Bolts firmly fix the filter screen to the air inlet and exhaust frames.

[0012] Furthermore, the filtration structure includes four collection boxes, a sieve, activated carbon, adsorbent cotton, and a filter membrane. The four collection boxes are arranged horizontally on one side of the upper surface of the baffle, and the sieve, activated carbon, adsorbent cotton, and filter membrane are arranged horizontally at the center of the four collection boxes.

[0013] Through the above technical solution, air flows inside the chamber. When it passes through the filtration structure, it first comes into contact with four horizontally arranged boxes located on one side of the upper surface of the baffle. The air passes through the four boxes in sequence. Inside each box, different filter materials play a role. The air undergoes preliminary filtration through the sieve, intercepting larger particles of impurities. Next, the air enters the activated carbon to adsorb odors and some harmful substances in the air. Then, the absorbent cotton further adsorbs tiny particles. Finally, the filter membrane performs fine filtration, removing even smaller impurities, providing a cleaner air environment for the tobacco industry and helping to ensure the quality of tobacco products.

[0014] Furthermore, the purification structure includes a water tank, multiple heaters, an air inlet pipe, a drain solenoid valve, a water inlet solenoid valve, and two gas flow pipes. The water tank is located at the center of the lower inner wall of the tank body, with the multiple heaters arranged in a front-to-back arrangement at the center of the lower inner wall of the water tank. The air inlet pipe is located at the upper center of one side wall of the water tank, the drain solenoid valve is located at the lower center of the other side wall of the water tank, the water inlet solenoid valve is located at the upper center of the rear end face of the water tank, and the two gas flow pipes are located at the front and rear of the upper center of one side of the water tank. One end of the air inlet pipe passes through the lower end face of a baffle and extends to the upper end face of the baffle.

[0015] Through the above technical solution, after preliminary filtration, the air enters the water tank of the purification structure through the air intake pipe. The air intake pipe ensures that the air can smoothly enter the water tank from the corresponding area of ​​the chamber. Multiple heaters in the water tank start working to heat the water in the tank. The heated water produces water vapor, which comes into full contact with the air entering the water tank. Some impurities and harmful substances in the air are adsorbed, dissolved, or chemically reacted during the contact with the water vapor, thereby purifying the air. When the water in the tank needs to be replaced, the drain solenoid valve is opened to drain the used water. At the same time, new water is injected into the water tank through the water inlet solenoid valve to ensure the continuous and stable purification effect. The purified air is discharged from the water tank through two gas flow pipes and enters the air intake structure of the chamber.

[0016] Furthermore, one end of each of the eight bolts passes through one side wall of the two filters, one side wall of the air inlet frame, and one side wall of the air outlet frame, respectively, and leads to the interior of the air inlet frame and the air outlet frame, and the ends are threaded into the interior of the air inlet frame and the air outlet frame.

[0017] With the above technical solution, when the filter screen needs to be cleaned or replaced, it can be easily removed by simply unscrewing the bolts. The operation is simple and convenient, improving maintenance efficiency and reducing maintenance costs.

[0018] Furthermore, a door is provided at the center of the upper end face of the box.

[0019] The above technical solution connects to the box via hinges or other connection methods, allowing it to be opened and closed.

[0020] Furthermore, a filter rack is provided inside the box at one side of the center of the upper upper surface of the baffle.

[0021] The above technical solutions provide support and fixation.

[0022] This utility model has the following beneficial effects:

In this utility model, the high-efficiency and energy-saving ventilation device for HVAC in the tobacco industry is equipped with partition plates inside the air inlet frame and air outlet frame to separate the airflow, making the airflow more orderly and avoiding airflow turbulence.

By using bolts to fix the filter screen, it is easy to clean and replace the filter screen. The operation is simple and convenient, improving maintenance efficiency and reducing maintenance costs.

In this utility model, by adopting a design of four horizontally arranged boxes, each box is equipped with different filter materials, including a sieve, activated carbon, adsorption cotton and filter membrane, to perform multi-stage filtration of air in sequence, providing a cleaner air environment for the tobacco industry and helping to ensure the quality of tobacco products.

[0034] The air intake structure 5 inside the air intake frame 3 performs preliminary treatment on the incoming air, filtering larger particulate impurities and regulating airflow speed. The air treated by the air intake structure 5 enters the housing 1. Inside the housing 1, the air first comes into contact with the filter structure 6 located on one side of the center of the upper surface of the baffle 11. The various filter materials in the filter structure 6 perform multi-stage filtration, removing impurities of different sizes and properties. The filtered air continues to flow to the purification structure 8, where harmful substances in the air are adsorbed, dissolved, or reacted, further purifying the air. During its flow within the housing 1, the air enters the housing 1... The cavity 9 at the lower end near the other side has three sterilization lamps 10 arranged horizontally at the center of the front and rear inner walls to sterilize the air, killing bacteria, viruses and other microorganisms in the air. The air after filtration, purification and sterilization is discharged from the ventilation device through the exhaust frame 4 at the upper center of one side wall of the box 1. The air intake structure 5 inside the exhaust frame 4 may make final adjustments and optimizations to the discharged air. The box 1 has a door 2 at the center of the upper end face, which is connected to the box 1 by hinges and other connection methods, and can be opened and closed.

[0036] The four fans 503 inside the air inlet frame 3 and the air outlet frame 4 start, generating airflow. At the air inlet frame 3, the fans 503 draw outside air into the housing 1, and at the air outlet frame 4, the fans 503 expel the air from the housing 1. The air is initially filtered by the filter screen 501 as it passes through the air inlet frame 3 and the air outlet frame 4, blocking larger particles such as dust and fibers. The partition plate 504 separates the airflow, making the airflow more orderly and preventing turbulence. At the same time, the partition plate 504 may also help improve the working efficiency of the fans 503. This design allows the airflow generated by the fan 503 to pass more concentratedly through the filter screen 501 and the inside of the housing 1. Bolts 502 firmly fix the filter screen 501 to the air inlet frame 3 and the air outlet frame 4. One end of each of the eight bolts 502 passes through one side wall of each of the two filters 501, one side wall of the air inlet frame 3, and one side wall of the air outlet frame 4, respectively, and leads to the inside of the air inlet frame 3 and the air outlet frame 4. The ends are threaded into the inside of the air inlet frame 3 and the air outlet frame 4.

The operation is simple and convenient, improving maintenance efficiency and reducing maintenance costs.

[0037] The filter structure 6 includes four trays 601, a sieve 602, activated carbon 603, absorbent cotton 604, and a filter membrane 605. The four trays 601 are arranged horizontally on one side of the center of the upper surface of the baffle 11. The sieve 602, activated carbon 603, absorbent cotton 604, and filter membrane 605 are arranged horizontally at the center of the four trays 601. When air flows in the housing 1 and passes through the filter structure 6, it first comes into contact with the four trays 601 arranged horizontally on one side of the center of the upper surface of the baffle 11. The air passes through the four trays 601 in sequence. Inside each tray 601, different filter materials play their roles. The sieve 602 performs preliminary filtration of the air, intercepting larger particles of impurities. Then, the air enters the activated carbon 603 to adsorb odors and some harmful substances in the air. Next, the absorbent cotton 604 further adsorbs small particles. Finally, the filter membrane 605 performs fine filtration to remove even smaller impurities, providing a cleaner air environment for the tobacco industry and helping to ensure the quality of tobacco products.

[0038] The purification structure 8 includes a water tank 801, multiple heaters 802, an air inlet pipe 803, a drain solenoid valve 804, a water inlet solenoid valve 805, and two gas flow pipes 806.

The air inlet pipe 803 is located on the upper side of one side wall of the water tank 801. The drain solenoid valve 804 is located on the lower side of the other side wall of the water tank 801. The water inlet solenoid valve 805 is located on the upper rear side of the water tank 801. The two gas flow pipes 806 are located on the upper side of one side of the water tank 801, one at the front and one at the rear. One end of the air inlet pipe 803 passes through the lower end face of the baffle 11 and extends to the upper end face of the baffle 11. After preliminary filtration, the air enters the purification structure through the air inlet pipe 803. In the water tank 801 of the structure 8, the air inlet pipe 803 ensures that air can smoothly enter the water tank 801 from the corresponding area of ​​the box body 1. Multiple heaters 802 in the water tank 801 start working to heat the water in the water tank 801. The heated water will generate water vapor, which will come into full contact with the air entering the water tank 801. Some impurities and harmful substances in the air will be adsorbed, dissolved or reacted during the contact with the water vapor, thereby purifying the air. When the water in the water tank 801 needs to be replaced, the drain solenoid valve 804 is opened to drain the used water. At the same time, new water is injected into the water tank 801 through the water inlet solenoid valve 805 to ensure the continuous and stable purification effect. The purified air is discharged from the water tank 801 through two gas flow pipes 806 and enters the air intake structure 5 of the box body 1.

[0039] Working Principle: Air enters the ventilation device through the air inlet frame 3. The fan 503 is activated, generating airflow. At the air inlet frame 3, the fan 503 draws outside air into the housing 1. Inside the housing 1, the air first undergoes preliminary filtration through the filter screen 501, blocking larger particles such as dust and fibers. The partition plate 504 separates the airflow, ensuring more orderly airflow and preventing turbulence. Simultaneously, the partition plate 504 may also improve the working efficiency of the fan 503, allowing the airflow generated by the fan 503 to pass more concentratedly through the filter screen 501 and inside the housing 1. Bolts 502 securely fix the filter screen 501 to the air inlet frame. 3. Air flows within housing 1. When it passes through filter structure 6, it first comes into contact with four horizontally arranged boxes 601 positioned on one side of the center of the upper surface of baffle 11. The air passes through the four boxes 601 in sequence. Inside each box 601, different filter materials play a role. The air undergoes preliminary filtration through screen 602, intercepting larger particles of impurities. Next, the air enters activated carbon 603 to adsorb odors and some harmful substances in the air. Then, absorbent cotton 604 further adsorbs tiny particles. Finally, filter membrane 605 performs fine filtration, removing even smaller impurities, providing a cleaner air environment for the tobacco industry and helping to ensure the quality of tobacco products.

[0040] After initial filtration, air enters the water tank 801 of the purification structure 8 through the air inlet pipe 803. The air inlet pipe 803 ensures that air can smoothly enter the water tank 801 from the corresponding area of ​​the housing 1. Multiple heaters 802 in the water tank 801 start working to heat the water in the water tank 801. The heated water produces water vapor, which comes into full contact with the air entering the water tank 801. Some impurities and harmful substances in the air are adsorbed, dissolved, or reacted during the contact with the water vapor, thereby purifying the air. When the water in the water tank 801 needs to be replaced, the drain solenoid valve 804 is opened to drain the used water. At the same time, the water is replenished through the inlet pipe. Solenoid valve 805 injects new water into water tank 801 to ensure continuous and stable purification effect. The purified air is discharged from water tank 801 through two gas flow pipes 806 and enters the air intake structure 5 of box 1. The air enters the cavity 9 at the lower end of the box 1 on the other side. Three sterilization lamps 10 arranged horizontally at the center of the front and rear inner walls of cavity 9 sterilize the air and kill bacteria, viruses and other microorganisms in the air. The air after filtration, purification and sterilization is discharged from the ventilation device through the exhaust frame 4 at the upper center of one side wall of box 1. The air intake structure 5 inside the exhaust frame 4 may make final adjustments and optimizations to the discharged air.
