[0001] This utility model relates to the field of air purification, and more specifically, to an air purification device for a beef and mutton processing workshop. Background Technology

[0002] In the current food processing industry, beef and mutton processing workshops often suffer from poor air quality due to the large amounts of meat scraps and grease particles generated during meat processing, along with irritating gases such as ammonia and hydrogen sulfide produced by protein decomposition, and the proliferation of microorganisms. These pollutants not only affect the health of operators but also threaten the quality and safety of beef and mutton products, easily leading to food spoilage and excessive bacterial levels.

[0003] Traditional air purification equipment, such as simple filter devices or single activated carbon adsorption devices, is difficult to effectively remove a variety of complex pollutants. On the other hand, some equipment that uses chemical purification has problems such as waste of purification liquid and environmental pollution from waste liquid discharge. Moreover, the equipment is inconvenient to maintain, and frequent disassembly and cleaning can easily affect normal production in the workshop, making it difficult to meet the strict requirements of the food processing industry for hygiene and safety.

[0004] How to invent an air purification device for beef and mutton processing workshops to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example, refer to Figures 1-3 An air purification device for a beef and mutton processing workshop includes a workshop body 1, an installation pipe 2, and a connecting pipe 3. One end of the installation pipe 2 is fixed to the outside of the workshop body 1, and the other end is fixedly connected to the connecting pipe 3. The lower end of the connecting pipe 3 is connected to the side wall of the workshop body 1 to form an air circulation channel. An installation hole 11 is opened on the side wall of the workshop body 1 corresponding to the installation pipe 2. A water baffle 5 and a mounting frame 6 are fixedly installed inside the installation pipe 2. A motor 61 is installed on the mounting frame 6, and the output shaft of the motor 61... The fan blade 62 and cleaning plate 63 are installed on the top. When the motor 61 rotates, the fan blade 62 and cleaning plate 63 rotate synchronously. The rotation of the fan blade 62 generates negative pressure suction, which can draw the gas inside the workshop body 1 into the installation pipe 2 and connecting pipe 3 through the guide hood 4 to complete the purification cycle. The installation hole 11 has a positioning cavity 12 inside, and the positioning cavity 12 has a limiting groove 13 inside. The guide hood 4 is movably inserted into the installation hole 11. A filter area 41 is opened on the side of the guide hood 4 facing the fan blade 62 to filter... Zone 41 is used for preliminary filtration of the incoming gas. Two positioning blocks 42 are symmetrically arranged on the outer side of the flow guide 4. A limit plate 43 is rotatably connected to the positioning blocks 42. The flow guide 4 is limited by the positioning blocks 42 and the limit plate 43. A purification nozzle 7 is threadedly connected to the inner top wall of the flow guide 4. A liquid inlet pipe 71 corresponding to the purification nozzle 7 is opened on the side wall of the workshop body 1. The liquid inlet pipe 71 sprays purification liquid downward through the purification nozzle 7, which mixes with the inhaled gas to achieve absorption and purification of the gas. The bottom of the flow guide hood 4 has an opening, and the side wall of the workshop body 1 corresponding to the opening has a liquid storage chamber 8. The liquid storage chamber 8 is used to store the liquid sprayed by the purification nozzle 7. The top of the liquid storage chamber 8 penetrates the side wall of the mounting hole 11, and the bottom of the liquid storage chamber 8 has a drain pipe 81. The drain pipe 81 is used to discharge the waste liquid in the liquid storage chamber 8. An insert plate 9 is inserted into the inside of the mounting pipe 2. An activated carbon plate 92 is snapped into the inside of the insert plate 9. The activated carbon plate 92 can further absorb and filter the gas purified by the purification liquid.

[0024] It should be noted that the positioning block 42 is matched with the positioning cavity 12. When one end of the positioning block 42 abuts against the inner end of the positioning cavity 12, the position of the limiting plate 43 corresponds to the position of the limiting groove 13, ensuring the accurate position of the guide shield 4.

[0025] Reference Figures 3-5 The top of the insert plate 9 is provided with a handle 91, which makes it easy to pull out the insert plate 9 to replace the activated carbon plate 92. The lower end of the connecting pipe 3 is equipped with a filter plate 31. The end of the installation pipe 2 is flush with the end of the water baffle 5. The side wall of the filtration area 41 abuts against one end of the water baffle 5. The water baffle 5 is set in a conical shape to ensure that the gas can flow smoothly and at the same time prevent the purified liquid from entering the installation pipe 2.

[0026] It should be noted that: the inlet pipe 71 is connected to the external purification pump through a pipeline, and the end of the outlet pipe 81 is connected to the external circulation pipeline, which can discharge the waste liquid and perform circulation treatment. The cleaning plate 63 facing the filter area 41 is provided with soft bristles, and the ends of the soft bristles abut against the side wall of the filter area 41. When the cleaning plate 63 rotates, the soft bristles can effectively clean the filter area 41.

[0027] The working principle of the air purification device in the beef and mutton processing workshop is as follows: After the motor 61 starts, it drives the fan blades 62 on the output shaft to rotate at high speed, generating negative pressure suction. Under the action of negative pressure, the air in the workshop body 1 enters the mounting hole 11 through the filter area 41 of the guide hood 4, and flows into the mounting pipe 2 after being guided by the water baffle 5. After being purified in the mounting pipe 2, the air flows back to the workshop body 1 through the connecting pipe 3, forming an air circulation path.

[0028] When air passes through the filtration zone 41, the mesh structure intercepts suspended particles in the air, such as fine meat scraps and dust generated during meat cutting, achieving preliminary purification. An external purification pump delivers purification liquid, such as alkaline solution or deodorant, to the purification nozzle 7 inside the flow hood 4 through the liquid inlet pipe 71. The nozzle atomizes the liquid and sprays it out. The atomized purification liquid comes into full contact with the air and removes harmful gases such as ammonia, hydrogen sulfide, and other odor gases and microorganisms generated during meat cutting through neutralization, adsorption, and decomposition. The atomized droplets flow downward under gravity and flow into the liquid storage chamber 8 through the opening of the flow hood 4. The waste liquid is connected to the external circulation pipeline through the drain pipe 81 and can be reused in the purification nozzle 7 after sedimentation, filtration, and regeneration, reducing consumable costs and pollution emissions. After chemical purification, the air enters the installation pipe 2 and passes through the activated carbon plate 92 inside the insert plate 9. The porous structure of the activated carbon adsorbs and traps residual small molecule organic matter and odor gases such as volatile fatty acids, achieving deep purification.

[0029] At the same time, the motor 61 drives the cleaning plate 63 to rotate synchronously, and its soft bristles continuously wipe the surface of the filter area 41 to prevent the intercepted impurities from clogging the filter area 41 and ensure stable filtration efficiency. The insert plate 9 can be quickly pulled out through the handle 91 to replace the saturated activated carbon plate 92 without disassembling the entire device, thus improving maintenance efficiency.

[0030] The positioning block 42 matches the positioning cavity 12 in the mounting hole 11. After inserting the guide cover 4 into the mounting hole 11, rotate the limiting plate 43 to make it snap into the limiting groove 13 to achieve quick fixation. When disassembling, rotate the limiting plate 43 in the opposite direction to remove the guide cover 4, which is convenient for regular cleaning of the filter area 41 and the nozzle, making maintenance convenient and efficient.

[0031] This device forms a three-stage purification chain of "physical interception + chemical decomposition + activated carbon adsorption" to ensure that air quality meets standards. It can efficiently purify the air in beef and mutton processing workshops and meet the hygiene standards for food processing environments.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "join," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] It should be noted that the specific model and specifications of motor 61 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
