Description

Technical Field

[0001] The invention relates to the technical field of veterinary drug extraction and sterilization, in particular to a full-pipeline automatic sterilization process for veterinary drug extraction. Background Art

[0002] The solution after veterinary drug extraction is easily contaminated by bacteria during pipeline transportation, storage, and canning, especially the ubiquitous yeast, mold and Bacillus subtilis, which will cause losses such as bloating, rancidity, shortened shelf life, and unqualified products in the finished products. In order to ensure the quality stability of the product, the veterinary drug solution needs to be sterilized during production. Most of the existing full-pipeline sterilization is to pass high-temperature steam into the pipeline for sterilization. However, for longer conveying pipelines, high-temperature steam will cause energy loss during the sterilization process. Therefore, when sterilizing longer veterinary drug conveying pipelines, the rear conveying pipelines are prone to poor sterilization effects and sterilization failures. After steam sterilization, as the pipeline cools, a negative pressure environment will be generated in the conveying pipeline. At this time, if ventilation is allowed to occur, external bacteria will enter the conveying pipeline. If there is no ventilation, the negative pressure environment will easily affect the conveying pipeline, reducing the service life of the conveying pipeline.

[0003] To this end, the present invention provides a full-pipeline automatic sterilization process for veterinary drug extraction. Summary of the Invention

The present invention can prevent the sterilization effect from being poor at the rear end of the delivery pipe, thereby ensuring a sterile environment for veterinary drug delivery, ensuring the production quality of veterinary drugs, preventing veterinary drugs from being contaminated by miscellaneous bacteria, and ensuring the quality of veterinary drugs. The veterinary drugs can be heated by a steam heating pipe during transportation to sterilize the veterinary drugs; a large negative pressure environment generated after the pipeline is cooled to damage the delivery pipe can be prevented, thereby extending the service life of the delivery pipe.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] See also Figures 1 to 12 The present invention provides a technical solution: a full-pipeline automatic sterilization process for veterinary drug extraction, wherein automatic control valves are provided at the inlet and outlet of the tanks in the full pipeline, and a pressure balancing structure is provided on the pipelines of the full pipeline, comprising the following steps:

[0041] S1. Before extracting and preparing veterinary drugs, high-temperature and high-pressure steam is introduced into the entire pipeline from one side of the extraction tank 1 through the first steam inlet pipe 2 for sterilization;

[0042] S2. High-temperature and high-pressure steam is introduced into the steam heating pipe 6 through the second steam inlet pipe 29 to heat and compensate for the gradually cooling high-temperature steam in the delivery pipe 3.

[0043] S3. After the sterilization is completed, wait for the air temperature and pressure in the delivery pipe 3 to reach normal, detect the air pressure in the delivery pipe 3 through the air pressure detection structure, release the pressure through the pressure balance structure, and then prepare the veterinary drug through the extraction tank 1, centrifuge, concentrator and other structures in the whole pipeline. The sequence of veterinary drug preparation and full pipeline sterilization is the same as the veterinary drug preparation steps and sequence in the full pipeline automatic sterilization system for Chinese veterinary drug extraction disclosed in the patent with announcement number CN221266722U, and the veterinary drug is transported through the delivery pipe 3 in the whole pipeline;

[0044] S4, the veterinary drugs in the delivery pipe 3 are sterilized by high-temperature heating of the steam in the steam heating pipe 6, the steam in the steam heating pipe 6 is discharged through the pressure balance structure, and the heat energy of the steam is recovered by the heat recovery structure;

[0045] S5. The delivery pipe 3 is heated and kept warm by the heat recovery structure, and the condensed water generated by the heat recovery structure is processed by the drainage structure.

[0046] The pressure balancing structure includes a pressure-slowing pipe 9, and an ultraviolet sterilization structure is installed on the top of the pressure-slowing pipe 9. The heat recovery structure in S4 includes a water tank 10 and a water pipe 11. The water tank 10 is connected to the water pipe 11. The pressure-slowing pipe 9 corresponds to the water tank 10, and the water pipe 11 corresponds to the delivery pipe 3. The air pressure detection structure in S3 includes a sliding block 36 elastically fitted in the second steam inlet pipe 29, the sliding block 36 corresponds to the steam heating pipe 6, and the sliding block 36 corresponds to the pressure balancing structure.

[0047] In this embodiment, the ultraviolet sterilization structure includes a purification box 14 fixed on the pressure-reducing tube 9, an ultraviolet lamp 18 is fixed in the purification box 14, an air inlet 15 and an air outlet 16 are respectively provided on the upper and lower sides of the purification box 14, an activated carbon filter plate 17 is fixed in the air inlet 15, and the air outlet 16 is connected to the pressure-reducing tube 9.

[0048] Specifically, when a negative pressure environment is generated in the delivery pipe 3, air can be introduced into the delivery pipe 3 through the pressure-relief pipe 9. During the air intake, the external gas can pass through the air inlet 15 and be filtered through the activated carbon filter plate 17 before entering the purification box 14. The air is then sterilized by the ultraviolet lamp 18, thereby preventing external bacteria from entering the delivery pipe 3. The sterilized air then enters the pressure-relief pipe 9 and then enters the delivery pipe 3 through the first connecting cavity 7, thereby preventing a large negative pressure environment from being generated in the delivery pipe 3 and causing damage to the structure of the delivery pipe 3, thereby extending the service life of the delivery pipe 3.

[0049] The water tank 10 is located on the peripheral side of the pressure-reducing pipe 9, and a water inlet 42 is provided on one side of the water tank 10. A connecting pipe 12 is installed between the water tank 10 and the water pipe 11. The water pipe 11 is a spiral structure. The water pipe 11 is located on the peripheral side of the pipe wall of the delivery pipe 3. A water outlet 13 is provided at the end of the water pipe 11, and the water outlet 13 is located on the relatively outside of the delivery pipe 3. The inner cavity of the water tank 10 can be relatively thin, so as to ensure that the water can be heated to a higher temperature by steam.

[0050] Specifically, water can be added to the water tank 10 through the water inlet 42, and after heat exchange with the steam, it enters the water pipe 11 through the connecting pipe 12, so that the heat of the steam can be recovered. The water heated by the steam flows out through the water pipe 11 and the water outlet 13, and the hot water can be recovered, thereby realizing energy recovery, and the delivery pipe 3 can be heated by the hot water in the water pipe 11, which can achieve a certain pressure relief and heat preservation effect.

[0051] A first electric valve 4 and a second electric valve 5 are respectively installed at both ends of the delivery pipe 3, a third electric valve 24 is installed in the pressure-relief pipe 9, a first communicating cavity 7 and a second communicating cavity 8 are opened in the pipe wall of the delivery pipe 3, a first communicating port 23 is opened between the first communicating cavity 7 and the delivery pipe 3, a fourth electric valve 25 is installed in the first communicating port 23, a second communicating port 27 is opened between the second communicating cavity 8 and the delivery pipe 3, a fifth electric valve 26 is installed in the second communicating port 27, and a sixth electric valve 30 is installed in the second steam intake pipe 29.

[0052] Specifically, by starting the first electric valve 4 and the second electric valve 5, the veterinary drugs can be transported through the delivery pipe 3. When sterilization is performed, the first electric valve 4 and the second electric valve 5 are opened at this time, and the steam introduced through the first steam inlet pipe 2 can enter the delivery pipe 3, thereby sterilizing the delivery pipe 3. Then the sixth electric valve 30 is opened, so that steam can be introduced into the steam heating pipe 6 through the second steam inlet pipe 29, so that the steam that gradually cools down in the delivery pipe 3 can be heated to compensate, and the veterinary drugs can be heated when being transported, thereby realizing heating and sterilization of the veterinary drugs, ensuring a sterile environment for veterinary drug transportation, preventing the presence of bacteria in the veterinary drugs, and ensuring the production quality of the veterinary drugs.

[0053] When the temperature in the delivery pipe 3 drops, the third electric valve 24 can be opened, so that air can be introduced into the delivery pipe 3 through the pressure-relief pipe 9, thereby preventing the structure of the delivery pipe 3 from being damaged due to a large negative pressure and extending the service life of the delivery pipe 3; the fifth electric valve 26 can be opened to introduce steam into the delivery pipe 3 and the steam heating pipe 6 at the same time, so that the delivery pipe 3 can be sterilized separately, thereby achieving separate sterilization of a certain section of the entire pipeline and improving the flexibility of the device.

[0054] A first electrode sheet 38 is fixed on the sliding block 36, a fixed rod 39 is fixed in the second steam intake pipe 29, a second electrode sheet is fixed on the fixed rod 39, the second electrode sheet corresponds to the first electrode sheet 38, the first electrode sheet 38 is connected to the fourth electric valve 25 through a data line, a relay is installed between the first electrode sheet 38 and the fourth electric valve 25, a fixed block 32 is fixed in the second steam intake pipe 29, a plurality of second springs 37 are fixed between the fixed block 32 and the sliding block 36, a sixth connecting port 35 is opened in the fixed block 32, the sixth connecting port 35 is connected to the second steam intake pipe 29, a plurality of electromagnets 40 are fixed in the fixed block 32, a plurality of adsorption blocks 43 are fixed on the sliding block 36, the adsorption blocks 43 correspond to the electromagnets 40.

[0055] Specifically, when the temperature in the delivery pipe 3 gradually drops and negative pressure is generated, the larger negative pressure at this time will attract the sliding block 36 to slide downward, thereby driving the first electrode sheet 38 to move downward, so that the second electrode sheet is separated from the first electrode sheet 38, and the second spring 37 is stretched. At this time, the fourth electric valve 25 opens, and the external gas can be sucked into the delivery pipe 3, thereby having a pressure relief effect, preventing a large negative pressure from being generated in the delivery pipe 3, and extending the service life of the delivery pipe 3.

[0056] When the pressure in the delivery pipe 3 is balanced with the external pressure, the second spring 37 rebounds, which can drive the sliding block 36 to reset. The electromagnet 40 is energized, and the adsorption block 43 can be adsorbed and fixed by the electromagnet 40 to ensure the stability of the sliding block 36; when negative pressure is generated, and the suction force of the negative pressure is greater than the suction force of the electromagnet 40, the sliding block 36 can be driven down by the negative pressure. When the negative pressure is balanced, the suction force of the negative pressure is less than the suction force of the electromagnet 40, so that the sliding block 36 is reset by the electromagnet 40, and steam can be introduced. At this time, steam can be introduced into the steam heating pipe 6 to achieve thermal compensation, heating of veterinary drugs, etc.; the electromagnet 40 can also be de-energized and steam can be introduced into the second steam inlet pipe 29. At this time, the sliding block 36 can be pushed downward by the thrust of the steam, so that the fifth connecting port 34 is connected to the delivery pipe 3, so that the delivery pipe 3 can be sterilized separately, thereby improving the flexibility of sterilization of the entire pipeline and expanding the scope of application of the device.

[0057] The first connecting chamber 7 and the second connecting chamber 8 are both connected to the steam heating pipe 6, the second steam inlet pipe 29 is connected to the second connecting chamber 8, a blocking plate 21 is installed in the first connecting chamber 7, a plurality of first springs 22 are fixed between the blocking plate 21 and the cavity wall of the first connecting chamber 7, a plurality of blocking blocks 20 are fixed on the blocking plate 21, the blocking blocks 20 correspond to the steam heating pipe 6, and a plurality of eighth connecting ports 44 are opened in the blocking plate 21.

[0058] Specifically, when steam is passed into the steam heating pipe 6, the steam can push the blocking block 20 and the blocking plate 21 to slide, and the first spring 22 is compressed. At this time, the steam can be sent into the first connecting cavity 7 through the eighth connecting port 44, and then discharged from the pressure relief pipe 9. When steam is passed into the delivery pipe 3 through the second steam inlet pipe 29 or air enters the delivery pipe 3 for pressure relief, the first spring 22 can push the blocking plate 21 to drive the blocking block 20 to block the steam heating pipe 6, thereby preventing steam or air from entering the steam heating pipe 6 and affecting the pressure relief and sterilization, ensuring the pressure relief and sterilization effects, thereby extending the service life of the device and ensuring the production quality of veterinary drugs; when negative pressure is generated in the steam heating pipe 6, a certain amount of steam can enter through the second steam inlet pipe 29. At this time, not only can a large negative pressure be prevented from being generated in the steam heating pipe 6, but the delivery pipe 3 can also be heated to prevent the rapid cooling in the delivery pipe 3 from causing negative pressure to be generated faster, thereby protecting the delivery pipe 3.

[0059] The drainage structure includes a drainage pipe 19 fixed to the lower side of the delivery pipe 3 , a seventh electric valve 31 is installed in the drainage pipe 19 , and a third communication port 28 is opened at the bottom of the first communication chamber 7 , which is connected to the drainage pipe 19 .

[0060] Specifically, the pressure-relief tube 9 is cooled by the water tank 10, so that the heat of the steam blown out of the pressure-relief tube 9 is recovered, and the steam is condensed to form condensed water which enters the first connecting chamber 7, and the condensed water can be discharged through the drain pipe 19. It can also be set as two seventh electric valves 31. By opening the two seventh electric valves 31 in sequence, the condensed water can be discharged without stopping the steam flow, thereby improving work efficiency.

[0061] A plurality of fourth communicating ports 33 are provided on the side of the second steam intake pipe 29, which are communicated with the second communicating cavity 8. A cavity 41 is provided in the sliding block 36, and a plurality of fifth communicating ports 34 are provided on both sides of the cavity 41, which correspond to the fourth communicating ports 33. The sliding block 36 is slidably connected to the second steam intake pipe 29.

[0062] Specifically, steam enters the cavity 41 through the second steam inlet pipe 29, and then enters the steam heating pipe 6 through the fifth connecting port 34 and the fourth connecting port 33, and is heated by the steam heating pipe 6, thereby ensuring the sterilization effect of the device.

[0063] Working process: When the entire pipeline needs to be sterilized, steam is introduced through the first steam inlet pipe 2, and high-temperature and high-pressure steam is introduced into the entire pipeline from the side of the extraction tank 1 in turn for sterilization. After the steam enters the delivery pipe 3, steam is introduced into the steam heating pipe 6 through the second steam inlet pipe 29. The steam enters the cavity 41 through the second steam inlet pipe 29, and then enters the steam heating pipe 6 through the fifth connecting port 34 and the fourth connecting port 33. The steam can push the blocking block 20 and the blocking plate 21 to slide, and the first spring 22 is compressed. At this time, the steam can be sent into the first connecting cavity 7 through the eighth connecting port 44, and then discharged from the pressure-reducing pipe 9. At this time, the steam in the delivery pipe 3 can be heated by the steam in the steam heating pipe 6 to ensure the temperature of the steam in the delivery pipe 3, thereby ensuring the sterilization effect.

[0064] When negative pressure is generated in the delivery pipe 3, the larger negative pressure at this time will suck the sliding block 36 to slide downward, thereby driving the first electrode sheet 38 to move downward, so that the second electrode sheet is separated from the first electrode sheet 38, and the second spring 37 is stretched. At this time, the fourth electric valve 25 is opened, and the external gas can be sucked into the delivery pipe 3. The external gas can pass through the air inlet 15 and pass through the activated carbon filter plate 17 to enter the purification box 14, and then pass through the ultraviolet lamp 18 to sterilize the air, thereby preventing external bacteria from entering the delivery pipe 3, and then the sterilized air enters the pressure-relief tube 9, and then enters the delivery pipe 3 through the first connecting cavity 7, which can prevent the generation of a large negative pressure environment in the delivery pipe 3 from damaging the structure of the delivery pipe 3.

[0065] When the delivery pipe 3 is sterilized alone, the electromagnet 40 is powered off and steam is introduced into the second steam inlet pipe 29. At this time, the sliding block 36 can be pushed downward by the thrust of the steam, so that the fifth connecting port 34 is connected to the delivery pipe 3, and the steam can sterilize the delivery pipe 3. At this time, the steam can be discharged through the pressure-relief pipe 9 to ensure the flow of steam.

[0066] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
