Description

Technical Field

[0001] This utility model relates to the field of meat product processing technology, and in particular to a gas-liquid dual-circulation ozone sterilization device. Background Technology

[0002] Meat products often have a fishy smell, and ozone is frequently used to remove this odor. Ozone has strong oxidizing properties and can destroy the cell walls and cell membranes of bacteria, viruses, and other microorganisms, causing protein denaturation and thus achieving sterilization. Therefore, ozone is often used to sterilize and remove the fishy smell from meat products.

[0003] Current ozone deodorization technologies for meat products mostly employ an air compressor to generate gas, which is then combined with an ozone generator to produce ozone. The ozone is then directly injected into a water tank to remove the odor from the meat products submerged in the tank. For example, an ozone disinfection device for removing odors from aquatic products, disclosed in application number 202510455131.7, includes an ozone generating component for generating ozone and delivering it to a water treatment tank via a delivery pipe; an aquatic product treatment component for sterilizing and deodorizing the aquatic products with ozone water; an auxiliary dissolving component for optimizing the ozone dissolution efficiency and ensuring the formation of high-concentration ozone water; and a water cooling component for filtering, cooling, and recycling the treated water.

[0004] However, the following problems were found when using this ozone deodorization technology for meat products: after ozone gas enters the water tank, it will create an air explosion, and a large amount of ozone will escape from the water surface and enter the air. This not only leads to a large amount of ozone waste and low ozone utilization efficiency, but also causes a strong odor in the air in the production workshop. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: A gas-liquid dual-circulation ozone sterilization device, such as Figure 1 As shown, it includes a box 1 and a washing pool 18. The box 1 is a box with a front door that can be opened and closed.

[0031] like Figure 2 As shown, the housing 1 is equipped with an air supply device, an air purification device 9, an air dryer 10, an ozone generator 11, a gas-liquid mixing pump 14, a filter 20, and a power distribution cabinet 26.

[0032] The air supply device in this embodiment includes an air compressor 5, an air purifier 9, and an air dryer 10 connected in sequence by pipes. The air outlet of the air dryer 10 is connected to the air inlet of the ozone generator 11 by pipes.

[0033] The air compressor 5, air purification device 9, air dryer 10, ozone generator 11, gas-liquid mixing pump 14, filter 20, and power distribution cabinet 26 used in this embodiment are all existing technology equipment, and their specific structures will not be described in detail in this embodiment.

[0034] like Figure 1 and Figure 2 As shown, the enclosure 1 has a vertically arranged second partition 3, the power distribution cabinet 26 is located between the second partition 3 and the right side panel of the enclosure 1, and the second partition 3 and the left side panel of the enclosure 1 are connected by a horizontally arranged first partition 2.

[0035] Air compressor 5, air purification device 9, and air dryer 10 are located in the box 1 below the first partition 2, while ozone generator 11, gas-liquid mixing pump 14, and filter 20 are located in the box 1 above the first partition 2.

[0036] The installation positions of the air compressor 5, air purifier 9, air dryer 10, ozone generator 11, gas-liquid mixing pump 14, filter 20, and power distribution cabinet 26 are not fixed. Their positions can be adjusted according to the internal space layout of the enclosure 1. This embodiment only provides one layout method.

[0037] An air inlet window 4 is provided on the side wall of the housing 1. A filter screen is provided at the air inlet window 4. The air inlet of the air compressor 5 faces the air inlet window 4. A filter cover 6 is provided at the air inlet of the air compressor 5.

[0038] A first flow meter 7 and a first regulating valve 8 are installed on the connecting pipe between the air compressor 5 and the air purification device 9.

[0039] The outlet of the ozone generator 11 is connected to the inlet pipe of the Venturi high-efficiency mixer 27. A second pressure valve 12 and a second regulating valve 13 are provided on the connecting pipe between the ozone generator 11 and the Venturi high-efficiency mixer 27.

[0040] The outlet of the gas-liquid mixing pump 14 is connected to the first liquid outlet 15 through a pipe. The first liquid outlet 15 is fixedly installed on the side wall of the housing 1.

[0041] To ensure that the ozone and the cleaning liquid (mostly water) stored in the cleaning tank 18 are mixed by the gas-liquid mixing pump 14 and then evenly injected into the bottom of the cleaning tank 18, such as... Figure 1 and Figure 3 As shown, a water distributor 17 is provided at the bottom of the cleaning tank 18. The inlet of the water distributor 17 is fixedly installed outside the side wall of the cleaning tank 18, and the inlet of the water distributor 17 is connected to the outlet pipe of the first outlet 15. In this embodiment, the outlet of the water distributor 17 faces upward.

[0042] In order to allow for the circulation and replenishment of ozone in the low-concentration ozone water after reaction with materials (compared to the high-concentration ozone water after mixing via gas-liquid mixing pump 14) and the filtration of impurities in the ozone water, such as... Figure 1 and Figure 2 As shown, the upper side wall of the cleaning tank 18 is provided with an overflow port 1801.

[0043] The overflow port 1801 is connected to the inlet of the filter 20 via a return pipe. Specifically, as shown... Figure 1 As shown, the return water pipe includes a first return water pipe 21, a metal corrugated pipe 22, and a second return water pipe 23 connected in sequence. The end of the first return water pipe 21 away from the metal corrugated pipe 22 is connected to the inlet of the filter 20. The first return water pipe 21 is pre-fixed on the side wall of the housing 1. The end of the second return water pipe 23 away from the metal corrugated pipe 22 is connected to the overflow port 1801.

[0044] The metal corrugated pipe 22 can not only compensate for pipeline displacement caused by factors such as temperature changes and pressure fluctuations, ensuring the normal operation of the pipeline system, but also reduce vibration and noise, effectively absorbing vibration and noise in the pipeline system, thereby protecting pipeline equipment and improving the stability of system operation.

[0045] The outlet of filter 20 is connected to the inlet pipe of Venturi high-efficiency mixer 27, and the inlet of gas-liquid mixing pump 14 is connected to the outlet pipe of Venturi high-efficiency mixer 27. A third regulating valve 24 and a third flow meter 25 are provided on the connecting pipe between the outlet of filter 20 and Venturi high-efficiency mixer 27.

[0046] Multiple ultrasonic generators 19 are provided on the side wall of the cleaning tank 18, which are equidistantly arranged around its perimeter.

[0047] Air compressor 5, air purifier 9, air dryer 10, ozone generator 11, gas-liquid mixing pump 14, ultrasonic generator 19, and filter 20 are all electrically connected to distribution box 26.

[0048] Working principle: When in use, first inject clean water into the cleaning tank 18 as cleaning solution, ensuring that the liquid level is higher than the overflow port 1801, and put the materials to be cleaned (such as aquatic products, poultry or other meat products) into the cleaning tank 18.

[0049] Then, through the power distribution cabinet 26, start the air compressor 5, air purifier 9, air dryer 10, ozone generator 11, and gas-liquid mixing pump 14.

[0050] Air compressor 5 draws in air filtered through the filter screen and filter cover 6 at the air intake window 4 and compresses it. The compressed air is then purified and dried by air purification device 9 and air dryer 10 before being input into ozone generator 11 to generate ozone. During this process, the ozone generation rate of ozone generator 11 can be observed by the first flow meter 7 and adjusted by the first regulating valve 8 to regulate the rate at which compressed air is input into ozone generator 11.

[0051] Then, the ozone generated by the ozone generator 11 is piped into the Venturi high-efficiency mixer 27.

[0052] The gas-liquid mixing pump 14 simultaneously draws clean water from the cleaning tank 18 through the overflow port 1801 and the return water pipe into the filter 20 for filtration, and then into the Venturi high-efficiency mixer 27 for preliminary mixing with ozone. The ozone water after preliminary mixing enters the gas-liquid mixing pump 14 for further mixing to form high-concentration ozone water. During this process, the flow rate of ozone entering the gas-liquid mixing pump 14 can be adjusted by observing the second flow meter 13 and cooperating with the second regulating valve 12. The flow rate of filtered clean water entering the gas-liquid mixing pump 14 can be adjusted by observing the third flow meter 25 and cooperating with the third regulating valve 24 to control the ozone concentration in the formed high-concentration ozone water.

[0053] Then, the ozone generator 11 pumps high-concentration ozone water into the water distributor 17 located at the bottom of the cleaning tank 18. The water distributor 17 evenly injects the high-concentration ozone water upward into the cleaning tank 18, so that the high-concentration ozone water can fully contact the materials in the cleaning tank 18. During this process, the ultrasonic generator 19 arranged around the cleaning tank 18 generates ultrasonic waves, which fully mixes the high-concentration ozone water with the clean water and reacts fully with the materials. The upper layer of low-concentration ozone water after the reaction re-enters the filter 20 through the overflow port 1801 and the return water pipe. After the filter 20 filters out the impurities in the low-concentration ozone water, it enters the gas-liquid circulation pump 14 to replenish ozone and form high-concentration ozone water again for circulation.

[0054] Example 2: A gas-liquid dual-circulation ozone sterilization device. The difference between this example and Example 1 is that only one ultrasonic generator 19 is installed on the side wall of the cleaning tank 18, and the water distributor 17 is no longer installed. The outlet of the gas-liquid mixing pump 14 is directly connected to the bottom of the cleaning tank 18 via a pipe. Other structures are the same as in Example 1.

[0055] Example 3: A gas-liquid dual-circulation ozone sterilization device. The difference between this example and Example 1 is that the Venturi high-efficiency mixer 27 is no longer included. The outlet of the ozone generator 11 and the outlet of the filter 20 are directly connected to the inlet pipe of the gas-liquid mixing pump 14. Other structures are the same as in Example 1.

[0056] Example 4: A gas-liquid dual-circulation ozone sterilization device. The difference between this example and Example 1 is that the gas supply device in this example uses a gas storage tank, and the outlet of the gas storage tank is connected to the inlet pipe of the ozone generator 11. Other structures are the same as in Example 1.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
