Description
Technical Field
[0001] This utility model relates to the field of air supply equipment technology, and in particular to an air supply purification device for food processing. Background Technology
[0002] In the food processing industry, food safety and the quality of the production environment are of paramount importance. With consumers' increasing demands for food safety and the increasingly stringent standards in the food processing industry, the need for air purification in food processing environments is becoming more and more urgent. Air purification equipment used in food processing is a key device to ensure air quality during food production. Food processing workshops often generate various pollutants such as dust, microorganisms, and odors. If these are not effectively purified, they will not only affect food quality but may also lead to food contamination and endanger consumer health. Therefore, the development of efficient, easy-to-maintain, and effective air purification equipment has become an inevitable requirement for the development of the food processing industry.
[0003] Existing food processing air purification equipment comes in various forms in terms of structure and principle. Common equipment typically uses simple filters for preliminary filtration at the air inlet. These filters are mostly fixed in place by screws or slots, and their purification principle mainly relies on the physical barrier effect of the filter to intercept large particles of impurities in the air. At the air outlet, some equipment simply has an air outlet for air supply without precise airflow adjustment or efficient purification measures. For equipment with purification functions, multiple layers of filters or a single purifying agent adsorption method are often used to purify the air. For example, some equipment uses activated carbon filters to adsorb odors, but as the usage time increases, the activated carbon becomes saturated and cannot be replaced or regenerated in time, affecting the purification effect. Moreover, the internal mechanical structure of the equipment is often quite complex, requiring professional disassembly for maintenance, which consumes a lot of time and labor costs.
[0004] Existing air purification equipment for food processing suffers from serious problems in the maintenance of the purification layer. Because the purification layer is mostly fixedly installed, it accumulates a large amount of dust, impurities, bacteria, and other contaminants after prolonged use. Replacing or maintaining it is extremely difficult. The fixed installation requires specialized tools and cumbersome steps to disassemble the purification layer, such as first removing parts of the equipment casing and then gradually loosening the screws or clips securing the filter. This process is not only complex but also prone to damaging the equipment. Furthermore, the inconvenience of disassembly prevents timely maintenance and replacement of the purification layer according to the prescribed time intervals, leading to a gradual decline in the equipment's purification effect, affecting the air quality of the food processing environment, and increasing the risk of food contamination. Therefore, this paper proposes an air purification device for food processing to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an air purification device for food processing, aiming to improve the problem that the purification plate cannot be easily fixed or removed for maintenance in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A locking plate is slidably connected inside the limiting groove. A locking block is fixedly connected to one side of the limiting plate. The locking block is slidably connected inside the fixing shell.
[0009] As a further description of the above technical solution:
[0010] The starting assembly includes a pull rod and a push rod. The bottom of the pull rod is fixedly connected to the top of the card plate, and one end of the push rod is fixedly connected to the outer wall of the push plate.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1 - Figure 3This utility model provides an embodiment of an air purification device for food processing, comprising a switch 1. The switch 1 is made of a sturdy and durable metal shell, with good sealing and anti-interference capabilities. An air inlet 2 is provided inside the switch 1, and a primary dust filter is installed at the air inlet 2. The filter surface is made of finely woven metal wire, which can initially block larger dust particles from entering the device. An air outlet 3 is provided inside the switch 1. Two pipes 4 are provided inside the switch 1. Both pipes 4 are made of 1 mm thick stainless steel air ducts. This material is not only lightweight, but also has good thermal conductivity and strength, which can effectively guide airflow. An air outlet 5 is fixedly connected to one end of one pipe 4. A spherical air outlet 6 is fixedly connected inside the air outlet 5. The spherical air outlet 6 is composed of a flexibly rotatable plastic joint and a metal nozzle. The plastic joint has good flexibility and can rotate freely at multiple angles, making it easy to accurately blow the purified air to the required location. The air outlet 5 is slidably connected to the purification plate 10. The outer wall of the air outlet 5 is provided with a fixing component, which is used to fix the purification plate 10. The purification plate 10 is provided with a starting component, which is used to start the purification plate 10. One end of the other pipe 4 is fixedly connected to the exhaust port 8. A mosquito and fly filter 7 is provided on one side of the exhaust port 8. The mosquito and fly filter 7 is made of fine metal wire and the mesh size is smaller than the size of common mosquitoes and flies, which can effectively prevent mosquitoes and flies from entering the pipe 4. The exhaust port 8 is provided with a disassembly component, which is used to easily disassemble the mosquito and fly filter 7.
[0035] The fixing assembly includes a limiting plate 14, the outer wall of which is slidably connected to the interior of the purification plate 10. A fixing shell 9 is fixedly connected to the outer wall of the purification plate 10. A push plate 17 is slidably connected inside the fixing shell 9. The push plate 17 is made of rubber and has a sealing strip on its edge to maintain good sealing during sliding and prevent dust from entering the interior of the fixing shell 9. A limiting groove 11 is provided inside the purification plate 10. A spring 12 is provided inside the limiting groove 11. One end of the spring 12 is fixedly connected to the inner wall of the limiting groove 11, and the other end of the spring 12 is fixedly connected to the interior of the limiting plate 14. A locking plate 18 is slidably connected inside the limiting groove 11. A locking block 13 is fixedly connected to one side of the limiting plate 14 and slidably connected inside the fixing shell 9, thereby quickly fixing the purification plate 10 and facilitating its maintenance and replacement.
[0036] Specifically, in the daily operation of the processing plant, when air blowing is required in the factory, the operator can precisely push the purification plate 10 along a specific track into the air outlet 5, and then manually pull the clamping plate 18 to raise it. At this time, the spring 12 begins to rebound, causing the limiting plate 14 to move smoothly inside the limiting groove 11. As the limiting plate 14 moves, the connected clamping block 13 also moves synchronously until it slides into the fixed housing 9. The movement of the clamping block 13 will push the push plate 17, after which the operator can start the process. Switch 1, the livestock fan inside switch 1 starts operating efficiently, drawing air in through inlet 2. The air is then precisely guided through duct 4 to outlet 5. The air entering outlet 5 is filtered and purified by purification plates 10 to remove impurities and dust. The air is then evenly distributed into the factory through spherical vents 6 with adjustable angles, precisely blowing air onto workers and improving the working environment. After use, for easy maintenance, the operator can move push plate 17, which in turn moves the limiting plate. 14. Applying pressure to move it compresses spring 12. Since the contact surface between push plate 17 and clamping plate 18 is inclined, push plate 17 will push clamping plate 18 upward when it moves. When push plate 17 moves to the back of clamping plate 18, clamping plate 18 will fall naturally due to gravity, firmly fixing limiting plate 14. At this time, the operator can easily remove purification plate 10 for maintenance and other work, making equipment maintenance more convenient. After a period of use, purification plate 10 may accumulate dust, bacteria and other pollutants, affecting the purification effect. At this time, simply pull out purification plate 10 for cleaning or replacement. Compared with the traditional fixed installation of purification plate 10, this pull-out design greatly saves maintenance time and labor costs. In addition, different food processing scenarios may have different requirements for air purification. By replacing different types of purification plates 10, the purification efficiency of the equipment can be flexibly adjusted. In the sterile processing environment with extremely high air quality requirements, a high-efficiency filter purification layer can be replaced to ensure that the delivered air reaches a higher cleanliness standard.
[0037] Reference Figure 1 - Figure 3 The starting assembly includes a pull rod 15 and a push rod 16. The bottom of the pull rod 15 is fixedly connected to the top of the card plate 18, and one end of the push rod 16 is fixedly connected to the outer wall of the push plate 17.
[0038] Specifically, the lever 15 is used to lift the clamping plate 18, and the push rod 16 is used to move the push plate 17 horizontally, making the whole process easier. After the clamping plate 18 is lifted by the lever 15, the push rod 16 is used to push the push plate 17 to release the fixation of the purification plate 10, and the staff can easily pull the purification plate 10 out of the air outlet 5.
[0039] Reference Figure 1 , Figure 4and Figure 5 The exhaust vent 8 has a rotating groove 20, a locking groove 22, and a sliding groove 23 inside. The disassembly assembly includes a limiting ring 24 made of stainless steel with a polished, smooth, and rust-resistant outer surface, allowing it to slide stably inside the mosquito and fly filter 7. The outer wall of the limiting ring 24 is slidably connected to the inside of the mosquito and fly filter 7. A knob 19 is rotatably connected inside the limiting ring 24. The main body of the knob 19 is made of plastic with a non-slip texture for easy rotation and pressing by the operator. The outer wall of the knob 19 is slidably connected to the inside of the mosquito and fly filter 7. The mosquito and fly filter 7 has a spring 25 inside. One end of the spring 25 is fixedly connected to the outer wall of the limiting ring 24, and the other end of the spring 25 is fixedly connected to the inside of the mosquito and fly filter 7. One end of the knob 19 is fixedly connected to a locking post 21. The locking post 21 is made of metal and is cylindrical. Its end is rounded to facilitate sliding between the locking groove 22 and the sliding groove 23. The outer wall of the locking post 21 is slidably connected to the inside of the locking groove 22, the outer wall of the locking groove 22 is slidably connected to the inside of the rotating groove 20, and the outer wall of the locking groove 22 is slidably connected to the inside of the sliding groove 23, so as to facilitate its disassembly and cleaning, keep it clean and prevent debris from clogging it.
[0040] Specifically, when ventilation is required in the processing plant, the staff first adjusts the operating mode of the entire device through the exchange 1. Then, the livestock fan starts working, filtering the air inside the plant through the mosquito and fly filter 7 to block any mosquitoes, flies, or other debris that may be mixed in with the air. The filtered air is then guided through the exhaust vent 8 and pipe 4 and discharged outdoors through the outlet 3. After use, to maintain the good performance of the equipment and the air filtration effect, the mosquito and fly filter 7 needs to be cleaned. At this time, the staff... The operator presses knob 19. With the applied pressure, knob 19 moves the limiting ring 24 and compresses spring 25. Simultaneously, knob 19 causes the locking pin 21 to slide within the slot 22. Rotating knob 19 then causes the locking pin 21 to rotate 90 degrees within the rotating groove 20. Releasing knob 19 causes spring 25 to return, returning knob 19 to its original position. The locking pin 21 then slides out of the sliding groove 23, thus releasing the mosquito and fly filter 7. The operator can then easily remove it from the outer wall of the exhaust vent 8. Thorough cleaning is performed, allowing operators to quickly remove the bag-type mosquito and fly filter 7 from the exhaust vent 8 when cleaning or replacement is needed. For example, after daily work in the food processing workshop, staff can easily open the clips and remove the filter for cleaning. Compared to some methods that require tools or complicated steps for disassembly, this saves a lot of time and effort, improves maintenance efficiency, and the filter installation is equally convenient. Simply align the filter with the exhaust vent 8 and secure it with the clips to complete the installation. New filters can be quickly installed, reducing equipment downtime and ensuring that the air purification equipment can operate continuously and stably during food processing, thus protecting the air quality in the workshop. The convenient disassembly and installation method allows for more frequent cleaning of the filter. Mosquitoes, flies, and dust easily adhere to the bag-type filter. If not cleaned in time, they will gradually clog the filter pores, affecting the ventilation of the exhaust vent 8. The clip structure facilitates disassembly, ensuring that the filter is always in a good ventilation state, maintaining a stable air output effect, and creating a suitable air environment for food processing.
[0041] Working principle: When blowing air into the processing plant, the purification plate 10 can be pushed into the air outlet 5, and then the pull rod 15 can be pulled. The pull rod 15 drives the clamping plate 18 to rise. Then, the spring 12 rebounds and drives the limiting plate 14 to move inside the limiting groove 11. Subsequently, the limiting plate 14 drives the clamping block 13 to move and slide into the fixed housing 9, pushing the push plate 17. Then, the exchanger 1 can be started, and the livestock fan inside the exchanger 1 takes in air through the air inlet 2, and then guides the air to the air outlet 5 through the pipe 4. The purification plate 10 filters and purifies the incoming air, and then sends it into the factory through the spherical air outlet 6. At the same time, the angle of the spherical air outlet 6 can be adjusted to accurately blow air onto the workers. When exhaust is required, the adjustment device of the exchanger 1 is used, and then the livestock fan guides the internal air filtered by the mosquito and fly filter 7 through the exhaust outlet 8 and the pipe 4, and then discharges it through the air outlet 3. After use, Then, push rod 16 can be pushed, which drives push plate 17 to move. Push plate 17 then moves limiting plate 14 to compress spring 12, facilitating installation. Simultaneously, because the contact surface with clamping plate 18 is inclined, clamping plate 18 is pushed upwards. When it moves to the back of clamping plate 18, gravity causes clamping plate 18 to fall, fixing limiting plate 14, allowing it to be removed for maintenance. Furthermore, button 19 can be pressed, which drives limiting ring 24. The device moves, and then the limiting ring 24 compresses the second spring 25. At the same time, the knob 19 drives the locking post 21 to slide inside the locking groove 22. Then, the knob 19 is rotated, which drives the locking post 21 to rotate inside the rotating groove 20, making it rotate 90 degrees. Then, the second spring 25 rebounds and drives the knob 19 back to its original position, so that the locking post 21 can slide out of the sliding groove 23, thereby removing the mosquito and fly filter 7 from the outer wall of the exhaust vent 8 for cleaning.
