Description

Technical Field

[0001] This invention relates to the field of meat processing workshop technology, specifically to a negative ion purification and disinfection device for meat processing. Background Technology

[0002] Meat processing workshops include: a pre-cooling workshop (where meat is pre-cooled, and the temperature depends on the specific processing technology); a cold storage workshop (where meat is processed, typically requiring a low-temperature environment, making its design essential); a quick-freezing workshop (to rapidly lower the core temperature of meat to the required level to meet processing standards and improve texture); and an aging workshop (where, after slaughter and natural cooling to room temperature, the meat carcasses are placed in a cooling room under specific temperature, humidity, and humidity conditions to break down lactic acid into carbon dioxide, water, and alcohol, which then evaporates). Simultaneously, the large-molecule adenosine triphosphate (ATP) enzyme within the cells breaks down the lactic acid into umami-rich glycosides (IMP, the main component of monosodium glutamate). After aging, the meat's texture and flavor are greatly improved, its pH is altered, and metabolic byproducts are decomposed and eliminated to the maximum extent, achieving harmlessness. This process also changes the meat's molecular structure, making it easier for the body to absorb and digest.

[0003] According to Chinese Patent CN213526644U, a disinfection device with negative ion purification effect for meat processing workshops is disclosed. This device includes a vehicle chassis panel. A mixing tank is fixedly mounted on the top left side of the chassis panel. A motor is fixedly mounted on the top center of the mixing tank. An agitator is fixedly mounted on the output end of the motor, extending into the mixing tank. A water inlet is located on the top left side of the mixing tank, and a funnel is located on the top right side. A water pipe is located at the bottom right side of the mixing tank, and a solenoid valve is mounted on the water pipe. A four-way connector is fixedly connected to the other end of the water pipe. The remaining three ports of the four-way connector are respectively fixedly connected to water pipe No. 2 and two sets of water pipe No. 3. A support block is installed on water pipe No. 2, and a spiral nozzle is fixedly connected to its other end. The spiral nozzle is fixedly mounted to the right end of the vehicle's floor panel via a mounting bracket. The two sets of water pipe No. 3 are distributed on the front and rear sides of the vehicle's floor panel, and an atomizing nozzle is fixedly mounted to the other end of each set of water pipe No. 3. Hydraulic cylinders are symmetrically arranged at the top center, slightly to the right, of the top of the vehicle's floor panel. Support plates are fixedly mounted to the top of the two sets of hydraulic cylinders, and a No. 2 motor is fixedly mounted to the top of the support plates. A rotating shaft is fixedly mounted to the output end of the No. 2 motor, and a brush disc is fixedly mounted to the bottom end of the rotating shaft, passing through the support plate and the vehicle's floor panel. A battery pack is located on the right side of the mixing tank, and a control panel is located at the top left side of the mixing tank. A push rod is located at the right end of the vehicle's floor, and casters are located at the four corners of the bottom of the floor. The mixing tank contains tourmaline powder and water. A motor drives a mixer to stir the tourmaline powder and water, ensuring a uniform mixture and more effectively generating negative ions to quickly produce a negative ion liquid. A misting nozzle sprays the negative ion liquid into the air. The negative ions not only adsorb impurities but also have an antibacterial effect. The antibacterial mechanism lies in the fact that when negative ions combine with bacteria, they cause structural changes or energy transfer, leading to bacterial death. This achieves the effect of disinfecting the vehicle. The device effectively disinfects the air in the room. By incorporating a spiral nozzle, the negative ion liquid flows into the nozzle and, under gravity, applies an impetus to the spiral blades, causing them to rotate. This, in turn, rotates the spiral nozzle, allowing the negative ion liquid to be evenly sprayed onto the ground. This design features a slow flow rate, conserving water and preventing splashing. It effectively removes impurities and inhibits bacterial growth on the ground. A brush disc, driven by a second motor, rotates and a hydraulic cylinder extends and retracts, lowering the brush disc to scrub the sprayed area, ensuring thorough disinfection. A control panel facilitates operation. Through these design optimizations, this invention boasts a simple structure, convenient operation, excellent disinfection effect, and strong practicality.

[0004] The aforementioned disinfection device requires vehicle-mounted propulsion during use, and when encountering large spaces, it also needs to be pushed to cover a limited distance. This requires continuous pushing to move it to the appropriate distance. In addition, the existing spraying mechanism requires a separate electrical drive, which will lead to resource waste over time. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] This invention provides a negative ion purification and disinfection device for meat processing. Compared with the prior art, it has the following advantages:

[0018] 1. This negative ion purification and disinfection device for meat processing uses a negative pressure spraying mechanism. Through the conveying pipe b and the drive box, the drawn-in air is discharged from the side pipe fixedly installed inside the exhaust pipe. This creates an internal circulation, allowing the internal air to continuously enter the conveying pipe a and mix with the negative ion disinfectant before flowing out. This saves time, expands the disinfection range, avoids the need to move and adjust the position, and can also filter particulate impurities mixed in the air.

[0019] 2. This negative ion purification and disinfection device for meat processing uses a combination of a drive box and a squeezing cylinder. Utilizing air pressure greater than the supporting force of a spring on a movable plate, the movable plate moves downwards. During this movement, it pushes a piston fixedly connected to the bottom of a push rod downwards. This movement squeezes the negative ion disinfectant stored inside the bearing chamber, causing it to be transported into the infusion tube a. From there, it is transported into the connecting block and sprayed out through a spray nozzle. During spraying, it mixes with the inhaled gas, facilitating the addition of disinfectant during internal circulation, thereby expanding the disinfection range. Furthermore, the physical squeezing method saves resources and improves efficiency.

[0020] 3. This negative ion purification and disinfection device for meat processing uses an infusion tube b. Suction causes a baffle plate to flip, and during this flipping process, a movable shaft fixed to the outer wall of the mounting rod rotates. This opens the side of the infusion tube b, allowing suction to draw the liquid accumulated inside the negative ion disinfectant container into the container cavity for easy replenishment. When the movable shaft flips to a suitable distance, it is stopped by a stop rod. As the piston moves downwards, the suction disappears, and the pushing force and the weight of the baffle plate allow it to adhere to the side of the infusion tube b, preventing backflow of liquid from the container cavity. This facilitates automatic liquid replenishment and improves efficiency. Attached Figure Description

[0030] Please see Figure 1-7This invention provides a technical solution: a negative ion purification and disinfection device for meat processing, comprising a workshop wall 1, with a negative pressure spraying mechanism fixedly installed on the outer wall of the workshop wall 1; the negative pressure spraying mechanism includes a circulation box 7, a conveying pipe a4, a gas collecting pipe a2, a suction pipe 3, and a cover plate 5; the gas collecting pipe a2 is fixedly installed at the bottom of the outer wall of the workshop wall 1, the suction pipe 3 is fixedly installed inside the gas collecting pipe a2, the cover plate 5 is snapped into the inside of the gas collecting pipe a2, the conveying pipe a4 is fixedly installed at the top of the gas collecting pipe a2, and the top of the conveying pipe a4 is fixedly installed with... A circulation box 7 is installed, with a conveying pipe b8 fixedly connected to its side. A drive box 9 is snapped onto the side of the conveying pipe b8, and the outer wall of the drive box 9 is fixedly connected to the surface of the workshop wall 1. An exhaust pipe 13 is snapped onto the side of the drive box 9. A cover plate 5 includes a circular filter screen 501 and an inlet 502. The circular filter screen 501 is fixedly installed at the bottom of the cover plate 5, and an inlet 502 is provided on the side of the circular filter screen 501. The inlet 502 and the suction pipe 3 fixedly connected to the outer wall of the air collecting pipe a2 are flush with each other. The interior of the circulation box 7 includes... The following components are included: outlet pipe 701, drive cylinder 702, exhaust fan 703, negative pressure pipe 704. The drive cylinder 702 is fixedly installed inside the circulation box 7. The exhaust fan 703 is fixedly installed inside the drive cylinder 702. The outlet pipe 701 is fixedly installed on the top of the exhaust fan 703. The negative pressure pipe 704 is fixedly installed on the bottom of the drive cylinder 702. The side of the outlet pipe 701 is fixedly connected to the outer wall of the delivery pipe b8. The top of the delivery pipe a4 is fixedly connected to the bottom of the negative pressure pipe 704. The inside of the bearing chamber 121 is fixedly connected to the side of the infusion tube b18. The interior of tube b18 includes a flow baffle 181, a mounting block 182, a baffle 183, a movable shaft 184, and a mounting rod 185. The mounting block 182 is fixedly mounted on the top side of the infusion tube b18. The baffle 183 is fixedly mounted on the top side of one side of the mounting block 182. The movable shaft 184 is movably mounted inside the other side of the mounting block 182. The mounting rod 185 is fixedly mounted on the top of the movable shaft 184. The bottom of the mounting rod 185 is fixedly connected to the flow baffle 181. The outer wall of the flow baffle 181 and the outer wall of one side of the infusion tube b18 are in contact with each other.

[0031] In this embodiment, when a negative pressure spraying mechanism is required, it can be laid according to the length of the workshop wall 1. Then, the circular filter screen 501, which is fixedly installed on the outer wall of the cover plate 5, is inserted into the inside of the air collection pipe a2. Then, the exhaust pipe 13 is installed on the side of the drive box 9. The exhaust pipe 13 can be laid along the top length of the workshop wall 1. At this time, it is only necessary to start the circulation box 7. Then, the exhaust fan 703, which is fixedly installed inside the drive cylinder 702, will draw air, causing the delivery pipe a4, which is fixedly connected to the bottom of the negative pressure pipe 704, and the suction pipe 3, which is fixedly installed on the outer wall of the air collection pipe a2, to enter the negative pressure pipe 704. During the suction process, the air at the bottom of the workshop wall 1 is drawn into the air collection pipe a2. As the gas flows, it is transported into the circular filter 501, which filters out impurities and particles mixed in the gas. The air is then discharged from the side pipe 14 fixedly installed inside the exhaust pipe 13 through the delivery pipe b8 and the drive box 9. This process creates an internal circulation, allowing the internal air to continuously enter the delivery pipe a4 and mix with the negative ion disinfectant before flowing out. This saves time and expands the disinfection range.

[0032] Specifically, a squeezing spray mechanism is internally connected to the delivery pipe a4; the squeezing spray mechanism includes a connecting block 6, an infusion pipe a11, a squeezing cylinder 12, a fixing ring 10, an infusion pipe b18, a negative ion disinfectant carrier box 16, an injection pipe 17, and a sealing cap 15. The connecting block 6 is internally connected to the delivery pipe a4, and the infusion pipe a11 is internally connected to the connecting block 6. The squeezing cylinder 12 is fixedly connected to the top of the infusion pipe a11, and the fixing ring 10 is fixedly installed on the outer wall of the squeezing cylinder 12. The top of the squeezing cylinder 12 and the bottom of the drive box 9 are movably connected, and an infusion spray mechanism is fixedly installed on one side of the bottom of the squeezing cylinder 12. A negative ion disinfectant carrier box 16 is fixedly installed on the side of the infusion tube b18. An injection tube 17 is fixedly installed on the outer wall of one side of the negative ion disinfectant carrier box 16. A sealing cap 15 is threaded onto the outer wall of the injection tube 17. The interior of the drive box 9 includes a baffle 901, a side opening 902, a threaded rod 904, a movable plate 905, a push rod 906, a spring 907, and a piston 908. Side openings 902 are opened on both sides of the drive box 9. A baffle 901 is fixedly installed on the top of the inner cavity of the drive box 9. The bottom of the baffle 901 is fitted and connected to the movable plate 905. The bottom sides of the connecting plate 903 are movably connected to the inside of the connecting plate 903. Threaded rods 904 are threadedly installed around the circumference of the connecting plate 903. The threaded rods 904 are threadedly connected to the bottom of the drive box 9. A push rod 906 is fixedly installed at the bottom of the movable plate 905. A spring 907 is movably sleeved on the top of the push rod 906. The spring 907 is located at the bottom of the movable plate 905. A piston 908 is fixedly installed at the bottom of the push rod 906. A bearing cavity 121 is opened inside the squeezing cylinder 12. The inside of the bearing cavity 121 and the outer wall of the piston 908 are sleeved together. The inside of the bearing cavity 121 and the infusion... The side of tube b18 is fixedly connected. The inside of infusion tube b18 includes a flow baffle 181, a mounting block 182, a stop bar 183, a movable shaft 184, and a mounting rod 185. The mounting block 182 is fixedly installed on the top side of the infusion tube b18. The stop bar 183 is fixedly installed on the top side of one side of the mounting block 182. The movable shaft 184 is movably installed inside the other side of the mounting block 182. The mounting rod 185 is fixedly installed on the top of the movable shaft 184. The flow baffle 181 is fixedly connected to the bottom of the mounting rod 185. The outer wall of the flow baffle 181 and the outer wall of one side of the infusion tube b18 are in contact with each other.

[0033] In this embodiment, when the gas is ejected from the inside of the delivery pipe b8, it enters the inside of the drive box 9. Because the baffle 901 and the movable plate 905 form a closed loop during the fitting process, when there is airflow inside the drive box 9, it will contact the movable plate 905 immediately. During the contact process, the air pressure in the drive box 9 is greater than the supporting force of the spring 907 on the movable plate 905, which causes the movable plate 905 to move downward. During the movement, it will push the piston 908 fixedly connected to the bottom of the push rod 906 to move downward. During the movement, it will squeeze the negative ion disinfectant stored in the bearing cavity 121, so that it is delivered into the inside of the infusion pipe a11. Then, it is delivered into the inside of the connecting block 6 through the infusion pipe a11 and sprayed out through the spray head 602. When sprayed, it will mix with the inhaled gas and can flow with the gas flow, which can facilitate the diffusion of the disinfection range. During the downward movement of the movable plate 905, it will squeeze the outer wall of the spring 907. When the spring 907 is squeezed to a certain extent, A rebound force will be generated, and the reset force will be greater than the air pressure of the airflow, causing the movable plate 905 to be lifted by the spring 907. When it is lifted, the push rod 906 will drive the piston 908 to move upward. During the movement, the piston 908 will generate suction, causing the liquid stored inside the infusion tube a11 to be drawn back into the bearing chamber 121. The suction will cause the flow-blocking plate 181 to flip. During the flipping process, the movable shaft 184 fixedly connected to the outer wall of the mounting rod 185 will rotate, which will open the side of the infusion tube b18. The suction will draw the liquid accumulated inside the negative ion disinfectant carrier box 16 into the bearing chamber 121, making it convenient to replenish the liquid. When the movable shaft 184 flips to the appropriate distance, it will be blocked by the stop rod 183. When the piston 908 moves downward, the suction will disappear. The pushing force and the gravity of the flow-blocking plate 181 can adhere to the side of the infusion tube b18, which can prevent the liquid inside the bearing chamber 121 from flowing back, thus facilitating automatic liquid replenishment and improving the efficiency of use.

[0034] Specifically, the interior of the connecting block 6 includes a side bayonet 601, a spray head 602, and a fixing pin 603. The side bayonet 601 is located on the side of the connecting block 6, and the interior of the side bayonet 601 is inserted into the outer wall of the infusion tube a11. The bottom of the fixing pin 603 and the side bayonet 601 are threadedly connected to the top of the infusion tube a11. The spray head 602 is fixedly installed on the back side of the connecting block 6, and the spray head 602 is located inside the delivery tube a4.

[0035] In this embodiment, when the connecting block 6 needs to be cleaned internally during continuous operation, the fixing pin 603 is removed from the inside of the connecting block 6 to remove the limit, and then the infusion tube a11 is removed from the inside of the connecting block 6. At this time, the connecting block 6 can be removed from the inside of the delivery tube a4, and the inside of the spray head 602 can be cleaned and used.
