Description

Technical Field

[0001] The invention relates to the technical field of animal carcass processing equipment, in particular to animal carcass sterilization and digestion processing equipment with a storage tank. Background Art

[0002] In biosafety level 3 or 4 large animal laboratories (ABSL-3 or ABSL-4 laboratories), large animals such as cattle, sheep, pigs, and horses are used as experimental subjects. GB 19489-2008 "General Requirements for Laboratory Biosafety" requires that ABSL-3 or ABSL-4 laboratories should have equipment and technology to reliably disinfect and sterilize animal carcasses and waste to prevent the spread of pathogenic microorganisms. In order to strengthen the biosafety management of veterinary vaccine manufacturers, Announcement No. 2573 of the Ministry of Agriculture of China stipulates that the "Biosafety Level 3 Protection Standards for Veterinary Vaccine Manufacturers" will be implemented from August 31, 2017. On October 26, 2018, the Ministry of Agriculture and Rural Affairs issued the "Biosafety Level 3 Protection Inspection and Acceptance Assessment Standards for Veterinary Vaccine Manufacturers" to further standardize the inspection and acceptance of biosafety level 3 protection for veterinary vaccine manufacturers. The above measures of the Ministry of Agriculture and Rural Affairs have enhanced the protection against pathogenic microorganisms during the development and production of veterinary vaccines. It is stipulated that veterinary vaccine manufacturers, especially the testing animal rooms and virus attack areas, should be designed in accordance with the requirements for ABSL-3 laboratories in GB19489-2008, and also require the installation of equipment that can reliably sterilize animal carcasses.

[0003] Technologies that can be applied to the sterilization of large animal carcasses usually include incineration, high-pressure steam, refining, alkaline hydrolysis, etc. Incineration can completely inactivate all pathogenic microorganisms, but my country does not allow laboratories to set up incineration facilities. It was once a common method to set up a double-door autoclave between the protection area and the auxiliary area to sterilize animal carcasses, but there is a risk that uneven heating may lead to incomplete sterilization of the inside of the carcass. Large-scale refining equipment can process animal carcasses into sterile liquids and granular solid substances under heating and high pressure conditions, but it cannot guarantee the killing of prions. Alkaline hydrolysis is a process that decomposes protein (including prions) structures, fats, and nucleic acids under the action of high temperature, high pressure, and strong alkali agents, assisted by stirring, to achieve complete sterilization.

[0004] CN104557156A discloses a device for harmlessly treating infected animal tissues, which uses alkaline hydrolysis technology to sterilize the carcasses of small animals such as chickens and rabbits. However, the products after treatment in this invention include solid residues and liquids, among which the liquid products have high BOD and pH values ​​and need to be biochemically treated in sewage treatment facilities or diluted in large proportions before they can be discharged, resulting in a heavy post-processing burden.

[0005] CN107597818A discloses a biosafety laboratory animal carcass harmless treatment equipment, which also uses alkaline hydrolysis process to treat small animals such as chickens and rabbits or large animals such as pigs, sheep, and cattle that carry pathogenic microorganisms. The treatment process includes: loading, pressure test, adding alkali solution, heating, pressure relief, adding neutralizer, drying, cooling, discharge, and cleaning, a total of 10 steps. The treated product is a dried mud-like substance, which reduces the burden of product post-processing. This invention also has certain problems: only one treatment tank is set, and all process flows are completed in the treatment tank, and the treatment cycle is long; the high-temperature steam heating treatment tank is slow to heat up, and the temperature uniformity and safety are poor; due to the weighing method of the integrated weighing sensor on the tank body, the biological seal through the floor requires a certain flexibility, and the flange plus sealing gasket method is used for sealing, which has the risk of long-term thermal expansion and contraction deformation leading to sealing failure, and does not consider the sealing problems of water, gas, electricity, etc. through the floor in the equipment; the treatment tank is vented out without considering the problems of biosafety and odor removal.

[0210] The processing process of the animal carcass sterilization and digestion processing equipment with a storage tank in this embodiment includes seven stages: preparation for operation, air tightness test, filling of alkali solution, heating and temperature rise, disinfection and dissolution, post-disinfection treatment, and treatment in a storage tank or dryer.

[0211] 1. Prepare for operation. Complete the preparation of alkali solution in the alkali solution preparation and filling unit 200; load the weighed animal carcasses into the main processing tank 905. The weighing method can be selected by installing an electronic hook scale on the overhead crane, and the weight of the loaded animal carcasses is input into the control system through the human-machine interface of the equipment; close the tank cover 901 of the main processing tank 905 and lock it.

[0212] 2. Air tightness test: Perform an air tightness test on the main processing tank 905 to ensure the safety of the subsequent operation process. The third pneumatic ball valve 303 and the fourth pneumatic ball valve 305 are opened, and compressed air U23 is injected into the main processing tank 905. When the pressure value fed back by the seventh pressure sensor 915 reaches the initial value of the air tightness test set by the control system, the third pneumatic ball valve 303 and the fourth pneumatic ball valve 305 are closed, and the injection of compressed air is stopped; within the air tightness test time set by the control system, the pressure value fed back by the seventh pressure sensor 915 is continuously detected; if the pressure value decays to the air tightness test termination pressure value set by the control system within the test time, it is judged that the air tightness test has not passed, and the control system issues an alarm and returns to the preparation for operation stage; if the pressure value is still greater than the air tightness test termination pressure value set by the control system after the test time ends, it is judged that the air tightness test has passed; after the test time ends, the control system controls the opening of the first pneumatic ball valve 801, and the tank body of the main processing tank 905 is exhausted and depressurized through the normal exhaust component of the exhaust processing unit 800 until the pressure value fed back by the seventh pressure sensor 915 returns to normal pressure.

[0213] 3. Add alkali solution. The control system calculates the amount of alkali solution to be added based on the weight of the animal carcasses input during the preparation phase and the ratio set inside the control system; the first pneumatic ball valve 210 and the second pneumatic ball valve 212 are opened, and the second pneumatic diaphragm pump 204 is operated (alkali solution solenoid valve 203), and the alkali solution is added to the main treatment tank 905. The control system measures the amount of alkali solution added through the feedback value of the alkali solution flow sensor 209 until the amount of alkali solution added reaches the calculated value, then stops the second pneumatic diaphragm pump 204, and closes the first pneumatic ball valve 210 and the second pneumatic ball valve 212.

[0214] 4. Heating and temperature increase. The control system heats according to the heating program of the temperature control unit 400, including high-temperature steam 490 until it is injected into the tank body to heat the tank body and its contents, and the first plate heat exchanger 408 heats the heat transfer oil in the heating jacket and then heats the main treatment tank body. The feedback value of the ninth temperature sensor reaches the temperature increase target value set by the control system, and the fifth pneumatic ball valve 404 is closed; during this process, the control system continuously detects the pressure value fed back by the seventh pressure sensor. If it is greater than the exhaust threshold, the control system controls the opening of the first pneumatic ball valve 801, and the main treatment tank 905 tank body is exhausted and depressurized through the normal exhaust component of the exhaust treatment unit until the pressure value fed back by the seventh pressure sensor drops to a certain proportion of the exhaust threshold.

[0215] 5. Disinfection and dissolution. During this process, the control system automatically adjusts the opening of the second steam regulating valve 407 according to the feedback value of the ninth temperature sensor, and then adjusts the heating amount of the heat transfer oil in the heating jacket, and controls the temperature in the main treatment tank to be stable at the target temperature rise value; the control system controls the stirring drive device 500 to drive the stirrer 910 to stir, and the stirring process is divided into four stirring speeds according to the disinfection and dissolution time process, namely, slow trial stirring, slow speed, medium speed, and fast speed. In the initial stage, the stirring is performed intermittently at a slow trial stirring within the set time, and then the stirring is continued at a slow speed within the set time, and then the stirring is continued at a medium speed within the set time, and finally the stirring is continued at a fast speed within the set time; until the accumulated time reaches the disinfection and dissolution set time set by the control system, this stage is completed.

[0216] 6. Post-disinfection treatment. This stage includes four steps: cooling and decompression, discharge, and cleaning. In the cooling and decompression step: the control system controls the stirring drive device 500 to drive the stirrer 910 to stir at a medium speed, and cools the main treatment tank 905 according to the cooling program of the temperature control unit 400; the control system detects the pressure value fed back by the seventh pressure sensor 915. When the pressure value is less than the cooling and decompression setting value, the fourteenth pneumatic ball valve 781 opens to release the remaining pressure in the main treatment tank 905, and the steam condensation unit 700 works at the same time; when the pressure value fed back by the seventh pressure sensor 915 is less than the discharge pressure setting value, the discharge step is entered.

[0217] The user selects whether to discharge to the dryer unit 600 or the storage tank unit A00.

[0218] When the material is discharged to the dryer unit 600, the main bottom valve 913 and the seventeenth solenoid valve 917 are opened, the third pneumatic ball valve 303 and the fourth pneumatic ball valve 305 are opened, and the material in the main treatment tank 905 is discharged into the dryer unit 600 through the main bottom valve 913 under the action of the compressed air U23. The user can observe the discharge situation in the main treatment tank 905 through the camera 904, and enter the cleaning step after the discharge is completed. In the cleaning step: the acid cleaning and neutralization unit 100 works, firstly, the main treatment tank is acid-washed by the spray ball 117, and then the main treatment tank 905 is water-washed by the spray ball 117; then the discharge procedure is repeated to discharge the material produced by acid washing and water washing into the dryer unit 600; the agitator 910 stops working.

[0219] When the material is discharged to the storage tank unit A00, the main bottom valve 913 and the eighteenth solenoid valve 918 are opened, the third pneumatic ball valve 303 and the fourth pneumatic ball valve 305 are opened, and the material in the main treatment tank 905 is discharged into the storage tank unit A00 through the main bottom valve 913 under the action of the compressed air U23. The user can observe the discharge situation in the main treatment tank 905 through the camera 904, and enter the cleaning step after the discharge is completed. In the cleaning step: the acid cleaning and neutralization unit 100 works, firstly, the main treatment tank is acid-washed by the spray ball 117, and then the main treatment tank is water-washed by the spray ball 117; then the discharge procedure is repeated to discharge the materials produced by acid washing and water washing into the storage tank unit A00; the agitator 910 stops working.

[0220] 7. After the processing flow in the main processing tank is completed, the processing flow of the next batch can be started, and at the same time, the dryer unit 600 or the storage tank unit A00 starts working.

[0221] 8. Processing in the dryer. It includes three steps: heating and drying, cooling and discharge. In the heating and drying step: first, the control system obtains the weight of the processed material in the drying tank 601 through the weighing sensor 632; the dryer unit starts the heating program until the fifth temperature sensor 609 reaches the drying temperature value set by the control system, and at the same time, the stirring motor 604 drives the stirring ring 605 to stir the processed material in the drying tank 601 and reverse the stirring at regular intervals. The steam condensation unit 700 works to capture evaporated water vapor, and the weighing sensor 632 continuously detects weight changes. When the weight is reduced to the drying weight loss ratio value set by the control system, the heating and drying is stopped. In the cooling step, the dryer unit starts the cooling program until the fifth temperature sensor 609 reaches the dryer discharge temperature value set by the control system. In the discharge step, under the action of compressed air U24, the material in the drying tank 601 is discharged outward through the drying main bottom valve 913.

[0222] If you choose to discharge to storage tank unit A00, pH neutralization will be performed first in storage tank unit A00 (circulating stirring promotes uniform neutralization). After neutralization, the user can choose to temporarily store it in storage tank A01 and then discharge it at an appropriate time or discharge it directly. When discharging, it will be directly discharged to the sewage treatment system.
