Abstract
Description
Technical Field
[0001] This utility model relates to the field of meat processing technology, and in particular to an odor adsorption and purification mechanism for meat processing workshops. Background Technology
[0002] Meat processing refers to the production and processing of meat products using specialized equipment and processes. Their work includes marinating, chopping, mixing, tumbling, filling, drying, smoking, steaming, cooling, and packaging. These processing steps must be completed within a meat processing workshop. Due to the characteristics of meat products, a large amount of odor is generated during processing in the workshop. Therefore, adsorption mechanisms are installed in the workshop for air purification. However, current adsorption mechanisms use a single purification method, resulting in low adsorption efficiency. For example, the patent application number CN220648544U uses a fixed activated carbon layer, which is easily saturated and cannot dynamically adjust the airflow distribution, reducing the adsorption effect. Therefore, we propose an odor adsorption and purification mechanism for meat processing workshops to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an odor adsorption and purification mechanism for meat processing workshops.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An odor adsorption and purification mechanism for meat processing workshops includes a conical filter barrel. The lower end of the conical filter barrel is connected to a protective box. The protective box contains a first rotating mechanism and a second rotating mechanism. An activated carbon filter screen is installed on the first rotating mechanism, and a metal-organic frame is installed on the second rotating mechanism. The metal-organic frame is fitted inside the activated carbon filter screen. A silica-alumina molecular sieve is fitted inside the activated carbon filter screen. The upper end of the silica-alumina molecular sieve is connected to a third rotating mechanism. Spiral guide plates are evenly spaced on the circumferential sidewalls inside the conical filter barrel.
[0006] Preferably, the first rotating mechanism includes a second drive motor installed on one side of the bottom inside the protective box. The output shaft of the second drive motor is connected to a first gear. The lower end of the activated carbon filter is connected to a second connecting rod. The lower end of the second connecting rod is rotatably connected to the bottom inside the protective box. A second gear is fixedly fitted on the second connecting rod, and the first gear and the second gear mesh with each other.
[0007] Preferably, the second rotating mechanism includes a third drive motor installed on the other side of the bottom inside the protective box. The output shaft of the third drive motor is connected to a third gear. The bottom of the conical filter barrel is rotatably fitted with an installation shaft. The upper end of the installation shaft is fixed to the lower end of the metal organic frame. The lower end of the installation shaft is fixedly fitted with a fourth gear, and the third gear and the fourth gear mesh. The connecting rod passes through the installation shaft.
[0008] Preferably, the third rotating mechanism includes a first drive motor fixed to the upper end of the conical filter barrel, the output shaft of the first drive motor is connected to a first connecting rod, and the lower end of the first connecting rod passes through the upper side wall of the conical filter barrel and is connected to the upper middle part of the silicon-aluminum molecular sieve.
[0009] Preferably, an air inlet pipe is connected to one side of the upper end of the conical filter barrel, and an air outlet pipe is connected to one side of the lower end of the conical filter barrel.
[0010] Preferably, the pore size of the silica-alumina molecular sieve is 0.5-0.7 nm.
[0011] In this invention, the three filter structures are arranged in a nested rotating manner. The outer layer is made of high specific surface area activated carbon (1200 m² / g), the middle layer is made of ZIF-8 metal-organic framework material, and the inner layer is filled with aluminosilicate molecular sieve (pore size 0.5-0.7 nm). The porosity of the three nested filter structures changes in a gradient (85% for the outer layer and 65% for the inner layer). The first rotating mechanism drives the activated carbon filter to rotate, the second rotating mechanism drives the metal-organic framework to rotate, and the third rotating mechanism drives the aluminosilicate molecular sieve to rotate, adopting an alternating rotating manner.
[0012] In this invention, during purification, odorous gas enters the conical filter barrel through the inlet pipe. Spiral guide plates evenly spaced along the inner sidewall of the conical filter barrel guide the gas in a spiral upward or downward flow path, allowing the gas to fully diffuse within the barrel and increasing the contact area and time with the filter structure. The second drive motor rotates the filter barrel via a first rotating mechanism composed of a first gear and a second gear. Activated carbon has a high specific surface area (1200 m² / g) and a high porosity (85%), enabling it to initially adsorb large organic molecules and particulate matter in the odorous gas through physical adsorption. The rotation ensures that all parts of the activated carbon are in full contact with the gas, avoiding local saturation. A third drive motor drives the mounting shaft to rotate via a second rotating mechanism composed of a third gear and a fourth gear, thereby rotating the metal-organic framework. The metal-organic framework material has a unique pore structure and a large specific surface area, exhibiting good adsorption selectivity for specific small-molecule odor substances, further removing odor components not fully adsorbed by the activated carbon. The rotation method improves its adsorption efficiency. The first drive motor drives the silicon-aluminum molecular sieve to rotate via a first connecting rod. The pore size of silica-alumina molecular sieve is 0.5-0.7nm, with a small porosity (65%), which enables it to screen and adsorb smaller molecules, especially some polar molecules and small odor substances, playing a role in fine filtration.
[0013] This utility model has the following advantages:
[0014] 1. It adopts a three-layer filter structure with a gradient change in porosity, which can adsorb odor molecules of different sizes and properties in stages, greatly improving the adsorption efficiency and making it more effective than single-purification adsorption mechanisms.
[0015] 2. The activated carbon filter, metal-organic frame and silicon-aluminum molecular sieve are rotated alternately by three rotating mechanisms, so that each part of each filter layer can fully contact the odor gas, avoiding the problem of local saturation in traditional fixed filter structures, extending the service life of filter materials and improving the overall adsorption effect.
[0016] 3. The spiral guide plate creates a spiral flow of gas within the conical filter barrel, optimizing the airflow distribution, ensuring sufficient contact between the gas and the filter structure, and further improving purification efficiency.
[0017] In summary, this invention uses different filter materials to adsorb different types of odor substances. Through the combination of multi-layer filter structures, it can achieve comprehensive and targeted purification of complex odor components in meat processing workshops, which is more effective than adsorption mechanisms with single purification methods. At the same time, the optimized airflow distribution ensures full contact between the gas and the filter structure, further improving the purification efficiency. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-6 Odor adsorption and purification mechanism for meat processing workshops, including a conical filter barrel 18, the conical design helps the gas to form a special flow pattern inside the barrel;
[0027] The lower end of the conical filter barrel 18 is connected to a protective box 17. The protective box 17 is equipped with a first rotating mechanism and a second rotating mechanism. An activated carbon filter screen 10 is installed on the first rotating mechanism, and a metal organic frame 4 is installed on the second rotating mechanism. The metal organic frame 4 is fitted inside the activated carbon filter screen 10. A silicon-aluminum molecular sieve 3 is fitted inside the activated carbon filter screen 10. The upper end of the silicon-aluminum molecular sieve 3 is connected to a third rotating mechanism. The purpose of multiple rotating mechanisms is to allow different filter structures to fully contact the odor gas, improve purification efficiency, break the limitations of traditional fixed filter structures, and make the purification process more comprehensive and efficient.
[0028] Spiral guide plates 14 are evenly spaced on the circumferential sidewall inside the conical filter barrel 18. The spiral guide plates 14 are designed to create a regular spiral upward or downward flow path for odorous gases in the barrel according to the principle of gas dynamics, thereby increasing the residence time and diffusion range of the gas in the barrel, allowing the gas to come into more full contact with the filter structure, and greatly improving the purification efficiency.
[0029] The first rotating mechanism includes a second drive motor 6 installed on one side of the bottom inside the protective box 17. The output shaft of the second drive motor 6 is connected to a first gear 5. The lower end of the activated carbon filter 10 is connected to a second connecting rod 7. The lower end of the second connecting rod 7 is rotatably connected to the bottom inside the protective box 17. A second gear 13 is fixedly mounted on the second connecting rod 7. The first gear 5 and the second gear 13 mesh with each other. The rotation of the activated carbon filter 10 can prevent local saturation due to prolonged contact with odorous gases, ensuring that all parts of the activated carbon can fully perform adsorption, thus improving the utilization rate and adsorption effect of the activated carbon.
[0030] The second rotating mechanism includes a third drive motor 8 installed on the other side of the bottom inside the protective box 17. The output shaft of the third drive motor 8 is connected to a third gear 9. The bottom of the conical filter barrel 18 is rotatably fitted with a mounting shaft 11. The upper end of the mounting shaft 11 is fixed to the lower end of the metal organic frame 4. The lower end of the mounting shaft 11 is fixedly fitted with a fourth gear 12, and the third gear 9 and the fourth gear 12 mesh. The connecting rod 7 passes through the mounting shaft 11. The metal organic frame material has a unique pore structure and a large specific surface area, which can selectively adsorb specific small molecule odor substances. The rotating setting allows the metal organic frame 4 to come into more full contact with the odor gas, improves its adsorption efficiency for specific odor components, and further optimizes the purification effect.
[0031] The third rotating mechanism includes a first drive motor 1 fixed to the upper end of the conical filter barrel 18. The output shaft of the first drive motor 1 is connected to a first connecting rod 2. The lower end of the first connecting rod 2 passes through the upper side wall of the conical filter barrel 18 and is connected to the upper middle part of the silicon-aluminum molecular sieve 3. An air inlet pipe 15 is connected to one side of the upper end of the conical filter barrel 18, and an air outlet pipe 16 is connected to one side of the lower end of the conical filter barrel 18. The pore size of the silicon-aluminum molecular sieve 3 is 0.5-0.7nm. The pore size of the silicon-aluminum molecular sieve 3 is 0.5-0.7nm, and it has a small porosity of 65%, which can screen and adsorb smaller molecules, especially some polar molecules and small molecule odor substances. The rotating silicon-aluminum molecular sieve 3 can come into more comprehensive contact with odor gases, achieve fine filtration, and ensure that the purified gas meets higher standards.
[0032] In this invention, the three filter structures are arranged in a nested rotating manner. The outer layer is made of high specific surface area activated carbon (1200 m² / g), the middle layer is made of ZIF-8 metal-organic framework material, and the inner layer is filled with aluminosilicate molecular sieve 3 with a pore size of 0.5-0.7 nm. The porosity of the three nested filter structures varies in a gradient from 85% in the outer layer to 65% in the inner layer. The first rotating mechanism drives the activated carbon filter screen 10 to rotate, the second rotating mechanism drives the metal-organic framework 4 to rotate, and the third rotating mechanism drives the aluminosilicate molecular sieve 3 to rotate, adopting an alternating rotating manner.
[0033] In this invention, during purification, odorous gas enters the conical filter barrel 18 through the inlet pipe 15. Spiral guide plates 14, evenly spaced on the inner sidewall of the conical filter barrel 18, guide the gas to form a spiral upward or downward flow path, allowing the gas to fully diffuse within the barrel and increasing the contact area and time with the filter structure. The second drive motor 6 rotates the filter barrel via a first rotating mechanism composed of a first gear 5 and a second gear 13. The activated carbon, with a high specific surface area of 1200 m² / g and a high porosity of 85%, can initially adsorb large molecular organic matter and particulate matter in the odorous gas through physical adsorption. The rotating mechanism ensures that all parts of the activated carbon can fully contact the gas, avoiding localized saturation. The third drive motor 8 drives the mounting shaft 11 to rotate via the second rotating mechanism composed of the third gear 9 and the fourth gear 12, thereby causing the metal-organic framework 4 to rotate. The metal-organic framework material has a unique pore structure and a large specific surface area, and has good adsorption selectivity for specific small molecule odor substances. It can further remove odor components that are not completely adsorbed by activated carbon. The rotation mode can improve its adsorption efficiency. The first drive motor 1 drives the silicon-aluminum molecular sieve 3 to rotate via the first connecting rod 2. The pore size of the silicon-aluminum molecular sieve is 0.5-0.7nm, with a small porosity of 65%, which can screen and adsorb smaller molecules, especially some polar molecules and small molecule odor substances, playing a fine filtration role.
