Abstract
Description
Technical Field
[0001] The invention relates to the technical field of high-temperature chemical treatment of diseased animals, in particular to a process of high-temperature chemical treatment of diseased animals-acid decomposition-co-production of calcium sulfate whiskers. Background Art
[0002] Regardless of whether they died of natural causes or epidemic diseases, animal carcasses often carry a variety of pathogens. If they are not handled or handled improperly, the carcasses will quickly decompose and emit a foul odor, causing pathogenic microorganisms to pollute the air, water sources and soil, causing the spread and spread of diseases. At the same time, people who have direct or indirect contact with them are likely to be infected. This requires timely harmless treatment of animal carcasses to prevent the growth of bacteria and the spread of diseases. The main methods for handling and disposing of animal carcasses include chemical refining of oils, direct landfill, landfill after high-temperature steaming and disinfection, composting, direct incineration, incineration in incinerators, etc.
[0003] After the existing chemical processing machines have completed the chemical processing of animal carcasses, the animal carcasses need to be discharged from the chemical processing machines through the discharge port and transferred to the filtering equipment for solid-liquid separation, which is a rather cumbersome process.
[0004] For example, a wet oxidation device for treating animal carcasses with announcement number CN212348695U comprises a frame and a treatment tank, both sides of the bottom of the treatment tank are connected with discharge pipes, the top of the storage box is rotatably connected with a box cover, the top of the box cover is connected with a connecting pipe, and a discharge valve is arranged on the surface of the discharge pipe located inside the frame. The utility model is used in conjunction with a storage box, a filter box and a treatment tank. After the animal carcasses are treated in the treatment tank, they are directly discharged into the storage box for solid-liquid separation. The process is simple, which shortens the time for treating the animal carcasses and improves work efficiency.
[0005] Traditionally, diseased animals are mostly treated in a pollution-free manner by chemically extracting oils. However, dead animals still have high economic value. If the purpose is just to treat the animal carcasses, the added value of the product is reduced. During the treatment process, the acid content in the acid hydrolysis product is high, and the utilization rate of the by-product calcium sulfate produced during the treatment process is low.
[0006] Therefore, we proposed a process of high temperature chemical preparation, acid hydrolysis and co-production of calcium sulfate whiskers from diseased animals. Summary of the invention
[0007] The object of the present invention is to provide a process for high-temperature chemical preparation-acid hydrolysis-co-production of calcium sulfate whiskers of diseased animals. In addition to neutralizing sulfuric acid in acid hydrolysis, it is also beneficial to increase the amino acid content in acid hydrolysis. The process can efficiently convert animal raw materials into amino acids, while making up for the defect of high acid content in the acid hydrolysis product. At the same time, the defect of low utilization of the by-product calcium sulfate produced is achieved, and the effective utilization of resources is achieved, so as to solve the above-mentioned problem that the acid content in the acid hydrolysis product is high and the utilization of the by-product calcium sulfate produced in the treatment process is low.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The secondary pressure boost liquefies all the raw materials except the insoluble inorganic salts, which is beneficial to the separation of oil and fat. The pressure in the chemical tank is used to press the material into the cyclone separator, which improves the centrifugal separation efficiency of the cyclone separator. The inner membrane of eggshell powder contains protein, which can not only neutralize sulfuric acid in acid hydrolysis, but also help to increase the amino acid content in acid hydrolysis. This process can efficiently convert animal raw materials into amino acids, while making up for the defect of high acid content in the acid hydrolysis product.

[0018] 2. When the motor is turned on, the rotating shaft and the connecting bearing rotate. The outer periphery of the spiral blade is thinner and has a sharp structure. After rotation, it can crush the animal fragments again, making it easier to heat and separate. The sharp end of the spiral blade is close to the inner wall of the inner cylinder, further improving the cutting efficiency.
[0019] 3. After the motor is turned on, multiple spiral blades can rotate at the same time. Multiple spiral blades are combined into a spiral structure. During the crushing process, not only can the animal fragments be heated evenly, but the spiral blades in the spiral structure can also drive the animal fragments to the position of the discharge pipe. After the animal fragments are heated, they can be directly discharged from the discharge pipe.
[0020] 4. When the spiral blades cut into bone structures or other harder structures, the spiral blades have a certain buffering force under the action of the scroll spring, which reduces the damage to the spiral blades caused by instantaneous impact and increases the service life of the device to a certain extent.
[0021] 5. When the motor stops rotating, multiple spiral blades droop naturally and are all set at the lower end of the device. After the animal fragments are processed, the hydraulic rod is opened to extend, the spiral blades are deformed and shortened, and the distance between adjacent spiral blades is also shortened, which makes it easier to push the animal fragments adhered to the inner wall of the device into the discharge pipe, greatly improving the discharge efficiency.
[0022] 6. The motor can also extend the hydraulic rod during the rotation process, so the distance between adjacent spiral blades is shortened. When the hydraulic rod is shortened, the adjacent first sleeves and spiral blades are reset, so the gap between the spiral blades can be adjusted, which is convenient for adjusting the size of the animal fragments after cutting, with good use effect and high processing efficiency.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] Example 1: Please refer to Figure 1 , a process for high temperature chemical preparation-acid hydrolysis-co-production of calcium sulfate whiskers from diseased animals, comprising the following steps: S1: The material is crushed into small pieces of 3-5 cm, and the temperature in the chemical tank reaches 160°C, and the pressure reaches 0.5MPa absolute pressure, and the pressure and temperature are maintained for 4 hours, and the pressure in the chemical tank is increased to 1-2.5MPa. The material is pressed into the cyclone separator by the pressure in the chemical tank, and the oil-water-slag three-phase separation is performed to obtain a purified oil and water-slag mixture; S2: The slag is transferred into the acid hydrolysis reactor, and 7%-20% concentrated sulfuric acid of the amount of slag is added to the temperature of 108-115°C and the pressure of 0.05-0.1MPa, and the reaction is carried out for 4-6h to obtain the acid hydrolysis solution; S3: Slowly add eggshell powder to the acid hydrolyzate to a pH of 8.5-10.5, and react at a hydrothermal temperature of 120-140°C for 1-5 hours. After centrifugation, the liquid is an amino acid stock solution and the solid is calcium sulfate whiskers.
[0027] In the above process, the secondary pressure increase liquefies all the raw materials except the insoluble inorganic salts, which is beneficial to the separation of oil and fat. The pressure in the chemical tank is used to press the material into the cyclone separator, which improves the centrifugal separation efficiency of the cyclone separator.
[0028] The purpose of acid hydrolysis is to further decompose the protein and peptide substances in the material into amino acids.
[0029] The inner membrane of eggshell powder contains protein, which not only neutralizes sulfuric acid in acid hydrolysis, but also helps to increase the amino acid content in acid hydrolysis.
[0030] This process can efficiently convert animal raw materials into amino acids, while making up for the defects of high acid content in the acid hydrolysis products and low utilization of the by-product calcium sulfate.
[0031] Example 2: Please refer to Figure 1-Figure 7 In S1, the chemical processing tank for high-temperature chemical processing of diseased animals includes a shell mechanism 1, a heat preservation mechanism 2 installed inside the shell mechanism 1, and a driving mechanism 3 installed inside the shell mechanism 1.
[0032] The outer shell mechanism 1 includes a first side plate 11 and a second side plate 12, an outer cylinder 13 is installed between the first side plate 11 and the second side plate 12, and a clamping piece 18 is fixedly installed on the inner wall of the first side plate 11 and the second side plate 12. The first side plate 11, the second side plate 12 and the outer cylinder 13 are combined into a closed space, and the diseased animals are put into the space for chemical treatment, which is used to treat the crushed diseased animals with high temperature and high pressure to achieve the purpose of pollution-free. Under the high temperature and high pressure environment, the moisture and oil in the carcasses of the dead animals are quickly evaporated and separated, the pathogens are effectively killed, and the stench is eliminated at the same time.
[0033] The insulation mechanism 2 includes an inner cylinder 21 rotatably mounted between two clamping members 18. The inner cylinder 21 is mounted between the first side plate 11 and the second side plate 12 through the clamping members 18. The inner cylinder 21 is arranged inside the outer cylinder 13, so that the device forms a closed insulation chamber for insulation and heat insulation of the device.
[0034] A feed pipe 22 is provided at the upper end of the inner cylinder 21 and is connected to the outer cylinder 13 through an opening and closing door (not shown in the figure). The crushed diseased animals are put into the device through the feed pipe 22. After the door is closed, the inside of the device can perform heat preservation and high-pressure operation. A discharge pipe 24 is provided at the lower end of the inner cylinder 21 and is connected to the outer cylinder 13 through an opening and closing door. The discharge pipe 24 is also provided with a door that can be opened and closed. After the diseased animals are chemically processed, they can be pressed out through the discharge pipe 24 to enter the cyclone separator for oil-water-slag three-phase separation, so as to obtain a purified mixture of oil, fat and water-slag.
[0035] The driving mechanism 3 includes a motor 31 and a rotating shaft 32 installed at the output end of the motor 31. The motor 31 is fixed on the outside of the device. After being turned on, it can drive the rotating shaft 32 to rotate, and is used to stir the animal fragments inside the device to achieve uniform pressure and heating. Two connecting bearings 33 are fixedly installed on the rotating shaft 32. The two connecting bearings 33 are rotatably connected to the first side plate 11 and the second side plate 12 respectively, thereby ensuring the stability and flexibility of the rotation of the rotating shaft 32.
[0036] Example 3: Please refer to Figure 4-Figure 7 The shell mechanism 1 also includes a support leg 14 fixedly mounted on the lower end of the outer cylinder 13 for supporting the device. A fixing plate 15 is fixedly mounted on one side of the second side plate 12. The motor 31 is fixedly mounted on the upper end of the fixing plate 15 for fixing the motor 31.
[0037] There is a heat preservation chamber between the outer cylinder 13 and the inner cylinder 21. The upper end of the outer cylinder 13 is connected to a water inlet pipe 16, and the lower end of the outer cylinder 13 is connected to a water outlet pipe 17. Both the water inlet pipe 16 and the water outlet pipe 17 are equipped with openable and closable valves (not shown in the figure). Water used to generate steam is discharged into the heat preservation chamber through the water inlet pipe 16. After the chemical process is completed, the hot water is discharged through the water outlet pipe 17.
[0038] The heat preservation mechanism 2 includes a pressure gauge installation port 23 connected to the upper end of the inner cylinder 21. The pressure gauge is installed on the device through the pressure gauge installation port 23 for real-time monitoring of the pressure inside the device. A plurality of equally spaced steam holes 25 are installed on the inner wall of the inner cylinder 21. The steam generated by the hot water is discharged into the interior of the device through the steam holes 25 to ensure a continuous high temperature and high pressure environment inside the device.
[0039] In the pressing tank, the specific process of steam heating is as follows: Water is converted into steam through the existing steam generator, and then the steam is transmitted to the inside of the device through the steam hole 25, so that the animal pieces in the tank are heated, and the steam diffuses in the tank, and uses its convection and conduction characteristics to transfer heat energy to the medium in the tank, thereby achieving the purpose of heating.
[0040] Example 4: Please refer to Figure 4-Figure 10 A connecting mechanism 4 is provided on the periphery of the driving mechanism 3. The connecting mechanism 4 includes a first sleeve 41 rotatably mounted on the periphery of the rotating shaft 32. The first sleeve 41 has engaging grooves 42 on both sides thereof and a sliding groove 43 on the periphery thereof.
[0041] A rotating mechanism 5 is arranged on the periphery of the connecting mechanism 4, and the rotating mechanism 5 includes two second sleeves 51 rotatably mounted on the periphery of the first sleeve 41, and a clamping ring body 52 is fixedly mounted on the inner wall of the two second sleeves 51, and the clamping ring body 52 is rotatably mounted in the clamping groove 42, and a connecting rod 53 is fixedly mounted on both second sleeves 51.
[0042] A first lap rod 34 is fixedly mounted at one end of the connecting bearing 33. The first lap rod 34 is arranged on one side of the connecting rod 53. The connecting rod 53 rotates synchronously with the connecting bearing 33 under the action of the first lap rod 34. After rotation, the animal fragments can be stirred and mixed, thereby increasing the contact area between the fragments and the high temperature, thereby facilitating increasing the uniformity of heating.
[0043] A spiral blade 54 is installed between the two connecting rods 53. One end of the spiral blade 54 is slidably installed in the sliding groove 43. In the initial state, multiple spiral blades 54 naturally droop and are all arranged at the lower end inside the device. When the motor 31 is turned on, the rotating shaft 32 and the connecting bearing 33 rotate. When the first lap rod 34 on the connecting bearing 33 rotates to one side of the connecting rod 53, the first lap rod 34 drives the connecting rod 53, the spiral blade 54, the connecting rod 53, and the second sleeve 51 to rotate. The spiral blade 54 rotates along the sliding groove 43 until the spiral blade 54 rotates to the end of the sliding groove 43, and the corresponding first sleeve 41 rotates synchronously. The outer periphery of the spiral blade 54 is thin and has a sharp structure. After rotation, it can crush the animal fragments again to facilitate heating and separation. The sharp end of the spiral blade 54 is close to the inner wall of the inner cylinder 21, which further improves the cutting efficiency.
[0044] A second overlapping rod 55 is fixedly installed at one end of one of the connecting rods 53, and the second overlapping rod 55 is overlapped on one side of the adjacent connecting rod 53. The first spiral blade 54 is swung up and rotated under the action of the first overlapping rod 34, and the adjacent spiral blades 54 and the connecting rod 53 are swung up and rotated under the action of the second overlapping rod 55. Therefore, multiple spiral blades 54 can rotate at the same time. Multiple spiral blades 54 are combined into a spiral structure. During the crushing process, not only can the animal fragments be heated evenly, but the spiral blades 54 with a spiral structure can also drive the animal fragments to the position of the discharge pipe 24. After the animal fragments are heated, they can be directly discharged from the discharge pipe 24.
[0045] Example 5: Please refer to Figure 4-Figure 10 A spiral spring 56 is fixedly installed at one end of the clamping ring body 52. The spiral spring 56 is arranged in the clamping groove 42 and is also fixedly connected to the groove wall of the clamping groove 42.
[0046] During the rotation of the spiral blade 54 along the sliding groove 43, the clamping ring body 52 fixedly connected to the spiral blade 54 through the second sleeve 51 rotates in the clamping groove 42, and the corresponding volute spring 56 adaptively expands and contracts. When the spiral blade 54 cuts into the bone structure or other harder structure, the spiral blade 54 has a certain buffering force under the action of the volute spring 56, which reduces the damage to the spiral blade 54 caused by instantaneous impact, and increases the service life of the device to a certain extent.
[0047] A cut-off portion 44 is provided in the middle of the first sleeve 41 . A telescopic rod 45 is installed inside the cut-off portion 44 . The telescopic rod 45 is used to connect two inner walls of the first sleeve 41 . An elastic member 46 is installed on the first sleeve 41 .
[0048] A rotating disk 35 is rotatably mounted on one end of the connecting bearing 33 away from the discharge pipe 24 , and a hydraulic rod 36 is fixedly mounted on one end of the rotating disk 35 .
[0049] When the motor 31 stops rotating, the multiple second sleeves 51, the clamping ring body 52, the connecting rod 53, and the spiral blades 54 stop rotating, and the multiple spiral blades 54 droop naturally and are all arranged at the lower end inside the device. After the animal fragments are processed, the hydraulic rod 36 is turned on to extend, and one end of the hydraulic rod 36 squeezes the first sleeve 41. The length of the cut-off portion 44 between the first sleeves 41 is shortened, and the corresponding telescopic rod 45 and elastic member 46 are shortened. The spiral blades 54 are deformed and shortened, and the distance between adjacent spiral blades 54 is also shortened, which makes it easy to push the animal fragments adhered to the inner wall of the device into the discharge pipe 24, thereby greatly improving the discharge efficiency.
[0050] The motor 31 can also extend the hydraulic rod 36 during the rotation process, so the distance between adjacent spiral blades 54 is shortened. When the hydraulic rod 36 is shortened, the adjacent first sleeve 41 and spiral blades 54 are reset, so the gap between the spiral blades 54 is adjustable, which is convenient for adjusting the size of the animal fragments after cutting, with good use effect and high processing efficiency.
