Description

Technical Field

[0001] This invention relates to the field of air purification and filtration equipment technology, specifically to an air purification and filtration component used in beef processing. Background Technology

[0002] In beef processing, to ensure air freshness and reduce dust and bacteria, air purification and filtration are often necessary. Patent application CN202211185930.X discloses an air purification device for cleanrooms. This device is simple in structure, easy to use, low in cost, and has a low failure rate. During use, the coordinated operation of multiple structures effectively disperses the air entering the purification chamber, increasing the contact area between the air and the purification liquid and improving the purification effect. Furthermore, this device can actively capture airborne dust, further enhancing its purification effect. It is worthy of promotion and use. Patent application CN202411064276.6 discloses a multi-functional workshop air purification device. This device purifies workshop air through a purification mechanism and is equipped with a high-pressure dust removal mechanism. During operation, the device stores high-pressure gas and periodically sprays it into the filter housing. The gas is used to clean the dust that clogs or adheres to the filter cover, preventing clogging from affecting purification efficiency. A dust collection mechanism is linked to a high-pressure cleaning mechanism, both powered by a transmission mechanism. The dust collection mechanism's design allows gas to be ejected from the vent pipe, causing the dust clogging the filter cover's holes to fall off and be collected during the mechanism's rotation, improving ease of processing. This dust collection also enhances the equipment's practicality and functionality. According to the publicly available technical solution, existing air purification and filtration equipment has several drawbacks. First, when introducing outside air into the beef processing workshop, bacteria in the air can easily enter the workshop's interior, compromising the safety of beef processing. Second, when using hydrogen peroxide for air disinfection, the high temperature can cause the hydrogen peroxide to decompose, compromising disinfection effectiveness. Third, exhausting air from the beef processing workshop can lead to energy waste, hindering energy conservation for cooling or heating within the workshop. Summary of the Invention

[0008] Furthermore, a disinfection lamp is installed on the inner side of the sleeve by bolts, and a second disinfection lamp is installed on the inner side of both the upper and lower sleeves by bolts. The inner walls of the upper sleeve, lower sleeve, and sleeve are all coated with a reflective layer.

[0009] Furthermore, the top of one side of the water tank is bolted to the bottom of the lower sleeve, the tank cover is threaded onto the top of the other side of the water tank, the cotton net is adhered to the inner wall of the inlet, the cotton net is located on top of the filter screen, and a guide sleeve is welded to the water tank, one end of the guide sleeve is welded to the inlet.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. During installation of the air purification filter assembly in this beef processing plant, an installation port is opened on one side of the workshop, and the support plate is bolted to the outside of the workshop. The top plate is bolted to the top of the workshop, and the air duct is installed on the other side of the workshop. In use, the fan generates suction through the air duct, causing air to pass through the filter screen and enter the inner side of the inlet. The airflow then pushes the flapper into the inner side of the air box, flowing to the left along the gap in the outlet pipe, then through the gap in the connecting pipe into the inner side of the connecting sleeve, and finally being blown downwards by the fan through the air duct. The flapper then moves towards... Pulling the cable pulls the locking pin, which in turn stretches the spring and moves it out from the inside of the opening. This allows the hydrogen peroxide in the tank to pass through the connecting block and guide sleeve under the adsorption of the cotton thread and enter the inside of the inlet. The cotton mesh is then wetted, and the airflow carries away the hydrogen peroxide through evaporation. The cotton mesh greatly increases the evaporation area of ​​the hydrogen peroxide, ensuring the disinfection effect on the air. After being disinfected, the air carries the hydrogen peroxide into the inside of the connecting sleeve, where a disinfection lamp further sterilizes the air. At the same time, ultraviolet light decomposes the hydrogen peroxide, preventing it from affecting personnel safety and the quality of the beef.

[0016] 2. In the air purification filter component used in this beef processing, when the airflow flows upward in the inlet, hydrogen peroxide evaporates through the cotton mesh, simultaneously cooling the air. The cooled air enters the inner side of the guide shroud through the bottom, and then flows through the duct inside the water tank to cool the hydrogen peroxide in the tank. Finally, it flows back to the inner side of the inlet through the return shroud, effectively reducing the temperature of the hydrogen peroxide in the tank and preventing it from decomposing due to prolonged exposure to ambient temperature. This ensures the concentration of hydrogen peroxide and thus guarantees its disinfection effect.

[0017] 3. In use, the air purification and filtration components in this beef processing plant allow fresh outside air to be filtered and disinfected before being blown by a fan through a duct to the bottom of the opposite side of the workshop. Air from the top of one side of the workshop is filtered by a filter plate and then enters the inner side of the upper and lower sleeves, effectively improving airflow and ventilation within the workshop. As the air flows within the upper and lower sleeves, disinfection lamps disinfect the air in both sleeves, and a reflective layer enhances the intensity of ultraviolet light, ensuring effective disinfection and preventing bacteria from flowing out of the workshop, thus avoiding air pollution. The disinfected air then enters the inner side of the connecting pipe and flows out through the outlet pipe. Outdoor and indoor air undergo thorough heat exchange through the air box, upper and lower sleeves, connecting pipe, and outlet pipe, reducing the temperature difference between the inflowing and outflowing air and thus reducing heating or cooling energy consumption in the beef processing workshop.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1 to 9This invention provides a technical solution: an air purification and filtration assembly for beef processing, comprising a wind box 1 and a support plate 2. A filter assembly, including an inlet 3 and a filter screen 4, is installed on the wind box 1. An exhaust assembly, including a wind duct 6 and a fan 7, is also installed on the wind box 1. An exhaust assembly, including an upper sleeve 9 and a lower sleeve 10, is installed on the wind box 1. A heat exchange assembly, including a connecting pipe 11 and an outlet pipe 12, is installed on the lower sleeve 10. A storage assembly, including a water tank 15 and a tank cover 16, is installed on the inlet 3. A disinfection assembly, including a cotton mesh 17 and cotton thread 18, is installed on the water tank 15. A cooling assembly, including a conduit 20 and a guide cover 21, is installed on the water tank 15. A locking assembly, including a connecting block 24 and a locking pin 25, is installed on the water tank 15. The guide cover 21 is bolted to the inside of the inlet 3. Located at the top of the cotton mesh 17, one end of the conduit 20 is bolted to one side of the guide cover 21. The other end of the conduit 20 passes through the inner wall of the inlet 3 and through the inner side of the water tank 15, extending to the inner side of the inlet 3. The other end of the conduit 20 is welded with a return cover 22, which is located at the top of the guide cover 21 and at the bottom of the flap 27. During use, when the airflow flows upward in the inlet 3, the hydrogen peroxide evaporates through the cotton mesh 17, while simultaneously cooling the heat in the air. The cooled air enters the inner side of the guide cover 21 through the bottom, and then flows through the conduit 20 into the inner side of the water tank 15 to cool the hydrogen peroxide in the water tank 15. The air then flows back to the inner side of the inlet 3 through the return cover 22, effectively reducing the temperature of the hydrogen peroxide in the water tank 15 and preventing it from decomposing due to prolonged exposure to ambient temperature, thus ensuring the concentration of the hydrogen peroxide and its disinfection effect.

[0030] In this embodiment, the inlet 3 is welded to the bottom of one end of the air box 1. The filter screen 4 is bolted to the inner wall of the bottom of the inlet 3. The inlet 3 is connected to one end of the air box 1. A connecting sleeve 5 is welded to the bottom of the other end of the air box 1. The top of the air duct 6 is welded to the bottom of the connecting sleeve 5. The fan 7 is bolted to the inner side of the air duct 6. The upper sleeve 9 is bolted to the top of the air box 1. The lower sleeve 10 is bolted to the bottom of the air box 1. Filter plates 14 are bolted to one end of both the upper sleeve 9 and the lower sleeve 10. The support plate 2... Welded to the outer side of the bellows 1, the upper sleeve 9 has top plates 13 welded to both sides. The connecting pipe 11 is installed on the inner side of the other end of the bellows 1. Both ends of the connecting pipe 11 pass through the inner wall of the bellows 1 and are connected to the other ends of the upper sleeve 9 and the lower sleeve 10, respectively. One end of the outlet pipe 12 is welded to the connecting pipe 11, and the other end of the outlet pipe 12 passes through the bellows 1 and extends to the outer side of one end of the bellows 1. The connecting pipe 11 is connected to the outer side of the outlet pipe 12 through the outlet pipe 12. The connecting pipe 11 and the outlet pipe 12 are evenly distributed on the inner side of the bellows 1. The inner side of the connecting sleeve 5 is connected to the outer side of the bellows 1. Disinfection lamp 8 is installed via bolts. Disinfection lamp 29 is also installed via bolts on the inner sides of the upper sleeve 9 and lower sleeve 10. The inner walls of the upper sleeve 9, lower sleeve 10, and connecting sleeve 5 are coated with a reflective layer. During use, fresh outside air, after being filtered and disinfected, is blown by the fan 7 through the air duct 6 to the bottom of the other side of the workshop. Air from the top of one side of the workshop, after being filtered by the filter plate 14, enters the inner sides of the upper sleeve 9 and lower sleeve 10, effectively improving the airflow and ventilation within the workshop. The air in the workshop is cooled by the air passing through the upper sleeve 9 and lower sleeve 10. When the air flows inside, the disinfection lamp 29 disinfects the air inside the upper sleeve 9 and the lower sleeve 10 respectively, and uses the reflective layer to increase the intensity of ultraviolet rays to ensure the disinfection effect of the air, preventing the air in the workshop from carrying bacteria outward and thus avoiding air pollution. The disinfected air enters the inside of the connecting pipe 11 and then flows outward through the outlet pipe 12. The outdoor air and the indoor air exchange heat fully through the air box 1, upper sleeve 9, lower sleeve 10, connecting pipe 11 and outlet pipe 12, reducing the temperature difference between the inflowing and outflowing air, thereby reducing the heating or cooling energy consumption in the beef processing workshop.

[0031] In this embodiment, the top of one side of the water tank 15 is bolted to the bottom of the lower sleeve 10. The tank cover 16 is threaded onto the top of the other side of the water tank 15. The cotton mesh 17 is adhered to the inner wall of the inlet 3 and is located on top of the filter screen 4. A guide sleeve 19 is welded to the water tank 15, with one end of the guide sleeve 19 welded to the inlet 3. The connecting block 24 is welded to the inner walls of the water tank 15 and the inlet 3, respectively. Both the connecting block 24 and the guide sleeve 19 have through holes. One end of the cotton thread 18 is adhered to the inner wall of the water tank 15, and the other end of the cotton thread 18 passes through the through hole and connects to the inner wall of the water tank 15. A lever 23 is bolted to the top of the water tank 15, which is attached to the cotton mesh 17. One end of the lever 23 is secured to the bottom of the tank cover 16. A hinged plate 27 is installed on the inner wall of the inlet 3 via a pivot. Pull wires 28 are connected to the other end of the lever 23 and the bottom of the hinged plate 27. A locking pin 25 is installed on the top of the connecting block 24. The top of the locking pin 25 is connected to the top of the connecting block 24 via a spring 26. The bottom of the locking pin 25 passes through the connecting block 24 and extends to the top of the opening. The bottom of the pull wire 28 is connected to the top of the locking pin 25. During installation, an installation opening is made on one side of the workshop, and the support plate 2 is bolted to the outside of the workshop. The top plate 13 is bolted to the top of the workshop. The air duct 6 is installed on the other side of the workshop. In use, the fan 7 generates suction on the connecting sleeve 5 through the air duct 6, causing air to enter the inside of the inlet 3 after being filtered by the filter screen 4. The airflow then pushes the flap 27 into the inside of the air box 1. Inside the air box 1, the air flows to the left along the gap of the outlet pipe 12, then passes through the gap of the connecting pipe 11 into the inside of the connecting sleeve 5, and is then blown downwards by the fan 7 through the air duct 6. The flap 27 pulls the pull cable 28 upwards. Pulling pin 25 causes it to stretch spring 26 and move out from the inside of the opening. This allows the hydrogen peroxide in water tank 15 to pass through connecting block 24 and guide sleeve 19 under the adsorption of cotton thread 18 and enter the inside of inlet 3. The cotton net 17 is then wetted, and the airflow carries away the hydrogen peroxide through evaporation. The cotton net 17 greatly increases the evaporation area of ​​hydrogen peroxide, ensuring the disinfection effect on the air. After being disinfected, the air carries the hydrogen peroxide into the inside of connecting sleeve 5, where the disinfection lamp 8 disinfects the air again. At the same time, ultraviolet light decomposes the hydrogen peroxide, preventing it from affecting personnel safety and beef quality.

[0032] The air purification and filtration assembly in this beef processing plant provides power to all electrical equipment via an external power source. During installation, an installation port is opened on one side of the workshop, and the support plate 2 is bolted to the outside of the workshop. The top plate 13 is bolted to the top of the workshop, and the air duct 6 is installed on the other side of the workshop. In use, the fan 7 generates suction on the connecting sleeve 5 through the air duct 6, causing air to pass through the filter screen 4 and enter the inside of the inlet 3. The airflow then pushes the flap 27 into the inside of the air box 1. Inside the air box 1, the air flows to the left along the gap in the outlet pipe 12, then through the gap in the connecting pipe 11 into the inside of the connecting sleeve 5, and is then blown downwards by the fan 7 through the air duct 6. The flap 27 pulls the pull cable 28 upwards. Pulling pin 25 stretches spring 26, causing it to move out from the inside of the opening. This allows hydrogen peroxide in water tank 15 to pass through connecting block 24 and conduit 19 under the adsorption of cotton thread 18, entering the inside of inlet 3. The cotton mesh 17 is then wetted, and the airflow carries away the hydrogen peroxide through evaporation. The cotton mesh 17 significantly increases the evaporation area of ​​the hydrogen peroxide, ensuring effective air disinfection. After disinfection, the air carrying hydrogen peroxide enters the inside of connecting sleeve 5, where disinfection lamp 8 further sterilizes the air. Simultaneously, ultraviolet light decomposes the hydrogen peroxide, preventing it from affecting personnel safety and beef quality. As the airflow rises within inlet 3, the hydrogen peroxide evaporates through the cotton mesh 17, simultaneously disinfecting the air... The system cools the hydrogen peroxide in the air by passing through the bottom of the guide shroud 21 and then through the duct 20 inside the water tank 15. This cooling process further cools the hydrogen peroxide in the tank, and the air then flows back through the return shroud 22 to the inside of the inlet 3. This effectively lowers the temperature of the hydrogen peroxide in the tank 15, preventing it from decomposing due to prolonged exposure to ambient temperature and ensuring its concentration and disinfection effectiveness. During operation, fresh outside air, after filtration and disinfection, is blown by the fan 7 through the duct 6 to the bottom of the other side of the workshop. Air from the top of one side of the workshop, after being filtered by the filter plate 14, enters the upper sleeve 9 and the lower sleeve 10 respectively. The inner side effectively improves the airflow and ventilation effect in the workshop. When the air in the workshop flows inside the upper sleeve 9 and the lower sleeve 10, the disinfection lamp 29 disinfects the air in the upper sleeve 9 and the lower sleeve 10 respectively, and uses the reflective layer to increase the intensity of ultraviolet rays to ensure the disinfection effect of the air, prevent the air in the workshop from carrying bacteria outward, and thus avoid air pollution. The disinfected air enters the inner side of the connecting pipe 11 and then flows outward through the outlet pipe 12. The outdoor air and the indoor air fully exchange heat through the air box 1, upper sleeve 9, lower sleeve 10 and connecting pipe 11 and outlet pipe 12, reducing the temperature difference between the inflowing and outflowing air, thereby reducing the heating or cooling energy consumption in the beef processing workshop.
