Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-temperature and high-pressure resource processing of dead poultry, and particularly relates to a high-temperature and high-pressure resource processing device and process method for dead poultry. BACKGROUND

[0002] In the current development of large-scale and intensive livestock breeding industry, harmless treatment and resource utilization of dead poultry have become a key link to protect public health safety, ecological environment safety and sustainable development of livestock industry. Among them, the high-temperature and high-pressure resource processing technology has become one of the core technologies widely used in the current industry because it can achieve the dual goals of sterilization and inactivation and resource recovery of dead poultry.

[0003] The existing high-temperature and high-pressure resource processing technology for dead poultry generally follows the core process of "crushing-high-temperature and high-pressure sterilization-subsequent resource utilization": first, the carcass of dead poultry is broken by professional crushing equipment, which is decomposed into relatively uniform material to facilitate the uniform transmission of heat and pressure in the subsequent process, laying a foundation for efficient processing; then, the crushed material is put into a high-temperature and high-pressure reaction tank, and a high-temperature environment of 121-135 DEG C and a high-pressure environment of 0.1-0.3 MPa are formed in the tank by introducing high-temperature steam, so as to destroy the cell structure and biological activity of pathogenic microorganisms (such as bacteria, viruses, and parasite eggs) that may be carried in the dead poultry by the synergistic effect of high temperature and high pressure, achieving complete sterilization and inactivation. This step is also the key link to ensure the safety of subsequent resource products (such as meat and bone meal and oil).

[0004] However, in the actual application process, this technology faces a key technical bottleneck-the dead poultry itself contains a certain amount of natural moisture (such as free water in muscle tissue and body fluid), which will be fully mixed with the crushed material during the crushing process, resulting in a generally high water content (usually up to 60%-75%) of the crushed material.

[0005] The high water content will have a significant negative impact on the subsequent high-temperature and high-pressure sterilization effect: on the one hand, the high heat capacity of water will increase the difficulty of temperature rise in the high-temperature and high-pressure reaction tank, prolonging the time to reach the target sterilization temperature, and the barrier layer formed by water between the material particles will cause uneven pressure transmission, making it difficult for the core area of some materials to reach the expected sterilization conditions; on the other hand, high water content will also increase the energy consumption and difficulty of subsequent resource processing (such as drying and degreasing), reduce the quality and utilization rate of the final product, and even cause secondary pollution risk due to incomplete sterilization, which seriously restricts the efficiency and safety of the existing high-temperature and high-pressure resource processing technology.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 The present invention provides a technical solution: a high temperature and high pressure resource utilization treatment device for diseased and dead poultry and livestock, which aims to solve the problems of poor sterilization effect and high energy consumption caused by high moisture content of crushed materials in the existing high temperature and high pressure treatment process. Through structural optimization, the device achieves synergistic and efficient material pretreatment and sterilization treatment. The high-temperature and high-pressure resource treatment device for dead poultry in the embodiment comprises a main body 1, a high-temperature and high-pressure reaction mechanism 2, a sealing block 3, a lifting plate 4, a driving rod 5, a pressure receiving block 6, a fixing ring 7, a driving block 8, a lifting and stirring mechanism 9, an elastic sheet 10, a control box 11, a motor 12, a transmission shaft 13 and a feeding rack 14, and the connection relationship and functions of the components are as follows: Assembly of the main body 1 and the high-temperature and high-pressure reaction mechanism 2 The main body 1 serves as a support frame of the device, and the high-temperature and high-pressure reaction mechanism 2 is rotatably installed at the middle position inside the main body 1. The high-temperature and high-pressure reaction mechanism 2 comprises a reaction tank 201, a turnover cover door 202, a hand wheel 203, a signboard 204, a fixed sealing plate 205 and high-temperature and high-pressure pipes 206. The reaction tank 201 is transversely arranged inside the main body 1 and is used for containing the crushed dead poultry materials. Two groups of turnover cover doors 202 are symmetrically hinged to the top of the reaction tank 201. When closed, the ends of the two groups of turnover cover doors 202 that are close to each other are in a staggered superimposed state, so as to ensure the sealing performance of the top of the reaction tank 201 and facilitate the feeding and taking out of the materials after treatment. The hand wheel 203 is in transmission connection with the turnover cover door 202, and the staff can control the opening and closing of the turnover cover door 202 by rotating the hand wheel 203. The signboard 204 is fixed to the outer wall of the reaction tank 201 and is marked with the opening sequence number and the rotation angle of the turnover cover door 202, so as to guide the staff to operate in a standard manner and avoid affecting the sealing effect due to the wrong opening and closing sequence. The fixed sealing plate 205 is fixed to one end of the main body 1 and forms a movable sealing cooperation with one end of the reaction tank 201, so as to ensure that the high-pressure gas in the tank does not leak when the reaction tank 201 rotates. The two groups of high-temperature and high-pressure pipes 206 are all penetrated through the fixed sealing plate 205 and are in communication with the inside of the reaction tank 201. One group is used for feeding high-temperature steam into the reaction tank 201, and the other group is used for feeding high-pressure gas, which together create the environment required for sterilization in the reaction tank 201. Cooperation of the sealing block 3, the lifting plate 4 and the elastic sheet 10 The two groups of sealing blocks 3 are fixed to the inside of the main body 1 on both sides and are closely attached to the outer wall of the reaction tank 201, which is used to prevent the leakage of the materials to be treated from the gap between the reaction tank 201 and the main body 1. A vertical sliding groove is formed in each group of sealing blocks 3, and the two sides of the lifting plate 4 are embedded in the sliding grooves, so as to realize the lifting and sliding connection between the lifting plate 4 and the sealing block 3. The outside of the lifting plate 4 and the inside of the main body 1 are elastically connected through the elastic sheet 10. When the lifting plate 4 is lifted, the elastic sheet 10 is stretched and deformed and stores elastic potential energy. After the lifting force disappears, the elastic sheet 10 releases the elastic potential energy and drives the lifting plate 4 to fall back, so as to realize the reciprocating lifting movement of the lifting plate 4. Structure and installation of the lifting and stirring mechanism 9 One of the groups of lifting plates 4 is provided with a lifting stirring mechanism 9, which comprises a support 901, a rotating shaft 902, a gear 903, a toothed plate 904, a connecting plate 905, a guide rod 906, a spring 907, a top frame 908, a stirring cylinder 909, an inclined stirring blade 910 and a vertical stirring blade 911. The support 901 is fixed to the lifting plate 4 and is used to rotate and support the rotating shaft 902, so as to ensure the stability of the rotating shaft 902 during rotation. The rotating shaft 902 penetrates through the support 901 and is rotationally connected with the support 901. One end of the rotating shaft 902 extends to the inside of the main body 1, and the outside of the end is sleeved with the stirring cylinder 909. The inclined stirring blade 910 is fixed to the middle position outside the stirring cylinder 909, and the vertical stirring blade 911 is fixed to both sides of the stirring cylinder 909. The two blades work together to achieve the full dispersion of the material. The gear 903 is fixedly sleeved on the middle outside of the rotating shaft 902, and the toothed plate 904 is fixed to the top of the main body 1 and is engaged with the gear 903. When the lifting plate 4 drives the rotating shaft 902 to lift, the gear 903 slides along the toothed plate 904 and rotates, thereby driving the rotating shaft 902 to rotate synchronously, so that the inclined stirring blade 910 and the vertical stirring blade 911 have lifting and rotating actions. The connecting plate 905 is movably arranged on one side of the rotating shaft 902. The guide rod 906 is vertically fixed to the top of the connecting plate 905 and is used to guide the lifting movement of the lifting stirring mechanism 9 to avoid deviation during lifting. The top frame 908 is fixed to the top of the guide rod 906 and is provided with a sliding hole matched with the guide rod 906, which further limits the sliding track of the guide rod 906 and ensures the sliding stability. The spring 907 is sleeved outside the guide rod 906, and the two ends of the spring 907 are respectively in contact with the top of the connecting plate 905 and the bottom of the top frame 908. The spring 907 can buffer the impact force during the lifting of the lifting stirring mechanism 9 and assist in maintaining the stability of the whole mechanism. Transmission cooperation of the fixed ring 7, the driving block 8, the driving rod 5 and the pressure receiving block 6 The fixed ring 7 is fixed outside the two ends of the reaction tank 201, and a plurality of groups of driving blocks 8 are uniformly fixed outside the fixed ring 7 in the circumferential direction. One of the groups of lifting plates 4 is fixed to the bottom of the lifting plate 4 and below the lifting stirring mechanism 9. The driving rod 5 extends to the outside of the main body 1 at both ends, and the end is fixed with the pressure receiving block 6. The pressure receiving block 6 is matched with the driving block 8. When the fixed ring 7 rotates with the reaction tank 201, the driving block 8 intermittently contacts the pressure receiving block 6, thereby driving the lifting plate 4 to rise through the driving rod 5. Power transmission of the control box 11, the motor 12 and the transmission shaft 13 The control box 11 is fixed outside the main body 1, and the motor 12 is installed inside the control box 11. The control box 11 can protect the motor 12 and provide circuit protection. The output end of the motor 12 is connected with the transmission shaft 13 through the transmission belt. The end of the transmission shaft 13 away from the motor 12 is fixedly connected with the shaft center of the end of the reaction tank 201 away from the fixed sealing plate 205. When the motor 12 works, the transmission shaft 13 is driven to rotate through the transmission belt, and then the reaction tank 201 is driven to rotate relative to the main body 1, so that the material in the reaction tank 201 is tumbled, and local heating and uneven pressure are avoided; The setting of the feeding rack 14 The feeding rack 14 is fixed on the top of the main body 1 and covers the upper part of the reaction tank 201. The feeding rack 14 is used for receiving the to-be-processed dead poultry and livestock materials and guiding the materials to accurately fall into the reaction tank 201, and preventing the materials from scattering during the feeding process. In addition, the internal space of the feeding rack 14 and the outer wall of the reaction tank 201 form a preheating area. When the reaction tank 201 is in a high-temperature working state, the heat emitted by the reaction tank 201 can preheat the second batch of materials to be fed in the feeding rack 14, laying a foundation for subsequent sterilization treatment. Specific steps of the dead poultry and livestock high-temperature and high-pressure resource treatment process: The dead poultry and livestock are treated by using the dead poultry and livestock high-temperature and high-pressure resource treatment device. The specific steps are as follows: S1: material feeding operation The worker first checks the prompt information on the identification plate 204, opens the two groups of turnover cover doors 202 in sequence according to the opening sequence number and rotation angle marked on the identification plate 204, and then opens the two groups of turnover cover doors 202 by rotating the hand wheel 203, so that the turnover cover doors 202 are in the state of being turned up and inward. Then the first batch of crushed dead poultry and livestock materials are fed into the reaction tank 201 through the feeding rack 14. After the first batch of materials are fed, the hand wheel 203 is reversely rotated to close the two groups of turnover cover doors 202. At this time, the ends of the two groups of turnover cover doors 202 close to each other are in a staggered and superimposed state, so as to ensure the sealing effect of the reaction tank 201. Finally, the second batch of to-be-processed materials are fed into the feeding rack 14. A part of the bottom of the second batch of materials is in contact with the outer wall of the reaction tank 201, and is limited by the two groups of sealing blocks 3 to avoid leakage from the gaps on both sides of the reaction tank 201. S2: high-temperature and high-pressure sterilization treatment The motor 12 inside the start control box 11 is started, and the output end of the motor 12 drives the transmission shaft 13 to rotate through the transmission belt. Since the transmission shaft 13 is fixedly connected with the shaft center of the reaction tank 201 away from the fixed blocking plate 205, the reaction tank 201 is driven to rotate relative to the main body 1, so that the first batch of materials in the reaction tank 201 is tumbled. At the same time, the two groups of high-temperature and high-pressure pipes 206 penetrating through the fixed blocking plate 205 are used to introduce media into the reaction tank 201, one group of the high-temperature and high-pressure pipes 206 is used to introduce high-temperature steam, and the other group is used to introduce high-pressure gas, so that an environment meeting the sterilization requirements is formed in the reaction tank 201, and the first batch of materials is subjected to sterilization treatment. In this process, the fixed blocking plate 205 and the end of the reaction tank 201 are kept in active sealing, so as to ensure that the pressure in the reaction tank 201 is not leaked when the reaction tank 201 rotates.

[0022] S3: Preheating and dispersion treatment of the second batch of materials In the process of high-temperature and high-pressure sterilization of the reaction tank 201, the heat inside the reaction tank 201 is dissipated to the inside of the feeding rack 14 through the tank wall and the turnover cover door 202 of the reaction tank 201, so as to preheat the second batch of materials in the feeding rack 14, and reduce the heating energy consumption and time in the subsequent sterilization treatment. At the same time, the fixed ring 7 at the two ends of the outside of the reaction tank 201 is rotated synchronously when the reaction tank 201 rotates, the driving block 8 outside the fixed ring 7 rotates together with the fixed ring 7, and when the driving block 8 rotates to contact the pressure receiving block 6, the pressure receiving block 6 is intermittently lifted, the pressure receiving block 6 drives the lifting plate 4 to rise relative to the blocking block 3 through the driving rod 5, and the elastic sheet 10 is stretched and stores elastic potential energy; When the lifting plate 4 rises, the lifting and stirring mechanism 9 installed thereon rises synchronously, the stirring cylinder 909, the inclined stirring blade 910 and the vertical stirring blade 911 in the lifting and stirring mechanism 9 are located in the second batch of materials, and the second batch of materials is lifted and dispersed in the rising process. At the same time, when the shaft 902 rises with the lifting plate 4, the gear 903 fixed on the shaft 902 meshes with the fixedly installed tooth plate 904, the gear 903 slides along the tooth plate 904 and rotates, thereby driving the shaft 902 to rotate, so that the inclined stirring blade 910 and the vertical stirring blade 911 rotate at the same time of rising, and the dispersion effect on the second batch of materials is enhanced; When a group of driving blocks 8 extrude the pressure receiving block 6 to the top end, the driving block 8 continues to rotate and is separated from the pressure receiving block 6, the lifting plate 4 descends relative to the blocking block 3 and the main body 1 under the action of the elastic potential energy released by the elastic sheet 10, driving the lifting and stirring mechanism 9 to descend synchronously. In this process, the gear 903 slides reversely along the tooth plate 904, driving the shaft 902 to reverse, and the inclined stirring blade 910 and the vertical stirring blade 911 reversely rotate at the same time of descending, further dispersing the second batch of materials, realizing the reciprocating lifting of the lifting and stirring mechanism 9 and the forward and reverse rotation of the shaft 902, and ensuring that the second batch of materials is fully dispersed; S4: Alternating treatment operation of materials After the first batch of materials is completed in the reaction tank 201, the motor 12 is controlled to continue to work, driving the reaction tank 201 to rotate, so that the turnover cover door 202 at the top of the reaction tank 201 faces downward; then the turnover cover door 202 is opened by rotating the hand wheel 203, and the first batch of materials in the reaction tank 201 is discharged under the action of its own gravity; after the first batch of materials is completely discharged, the reaction tank 201 is reversely rotated, so that the turnover cover door 202 faces upward again, the turnover cover door 202 is opened, and the second batch of materials in the feeding rack 14 that have been preheated and dispersed fall into the reaction tank 201 under the action of gravity, and then the turnover cover door 202 is closed; S5: Continuous processing operation The steps of S2 to S4 are repeated, that is, the second batch of materials in the reaction tank 201 is subjected to high-temperature and high-pressure sterilization treatment, and the third batch of materials to be treated is put into the feeding rack 14 and preheated and dispersed, after the second batch of materials is treated, the second batch of materials is discharged and the third batch of materials is put in, and so on, to realize continuous high-temperature and high-pressure resourceful treatment of the dead and diseased poultry materials; Through the above device and process method, the problems of poor sterilization effect and high energy consumption caused by high moisture content of the materials in the existing treatment process can be effectively solved, the pretreatment and sterilization of the materials are cooperated, the treatment efficiency and safety are improved, and the continuous treatment is realized, which meets the treatment demand of the dead and diseased poultry in the large-scale breeding scene.

[0023] Working principle: when in use, first put the first batch of crushed materials to be treated into the reaction tank 201, wherein the two groups of turnover cover doors 202 of the reaction tank 201 face upward and are inwardly turned and opened, so as to facilitate the materials to enter the reaction tank 201 through the feeding rack 14; Specifically, the two groups of turnover cover doors 202 need to be opened in sequence by the hand wheel 203, and the opening sequence number and opening rotation angle information on the signboard 204 can be used by the workers to open the two groups of turnover cover doors 202 in sequence, and when the two groups of turnover cover doors 202 are closed to each other, the ends of the two groups of turnover cover doors 202 that are close to each other are in a staggered and superimposed state, which better guarantees the sealing effect of the reaction tank 201; When the first batch of materials enters the reaction tank 201 and the two groups of turnover cover doors 202 are closed, the second batch of materials to be treated is continuously put into the feeding rack 14, and a part of the bottom of the second batch of materials to be treated is in contact with the outer wall of the reaction tank 201 and is limited by the two groups of sealing blocks 3, so as to avoid the problem of leakage of the materials from the gaps on both sides of the reaction tank 201; At this time, the motor 12 inside the control box 11 is started, and the output end of the motor 12 drives the transmission shaft 13 to rotate through the transmission belt. Since the transmission shaft 13 is fixed to the shaft center position of one end of the reaction tank 201, the motor 12 can drive the reaction tank 201 to rotate relative to the main body 1. At the same time, high-temperature and high-pressure gas is introduced into the reaction tank 201 through the two groups of high-temperature and high-pressure pipes 206 of the fixed blocking plate 205 at the other end of the reaction tank 201. Specifically, one group of high-temperature and high-pressure pipes 206 introduces high-temperature steam, and the other group of high-temperature and high-pressure pipes 206 performs high-pressure treatment on the inside of the reaction tank 201. The fixed blocking plate 205 and one end of the reaction tank 201 are movably sealed, that is, the fixed blocking plate 205 does not rotate with the reaction tank 201 at this time. As can be seen from the above, the motor 12, the transmission belt, and the transmission shaft 13 are combined to drive the reaction tank 201 to rotate relative to the main body 1, breaking the static accumulation state of the material. At the same time, high-temperature steam and high-pressure gas are introduced into the reaction tank 201 through the two groups of high-temperature and high-pressure pipes 206, directly delivering the key medium required for sterilization. The rotation of the reaction tank 201 drives the internal material to tumble, avoiding uneven heating and pressure of local material, and ensuring that each part of the material can be exposed to a high-temperature and high-pressure environment. The high-temperature steam provides the high-temperature conditions required for sterilization, and the high-pressure gas maintains the high-pressure environment in the reaction tank 201. The combination of the two meets the core process requirements for killing pathogenic microorganisms and provides a safe material basis for subsequent resource processing. At this time, since the inside of the reaction tank 201 is in a high-temperature state, the heat inside the reaction tank 201 will to some extent penetrate the reaction tank 201 and the turnover cover door 202. The heat emitted can preheat the second batch of materials inside the feeding rack 14 at the top of the reaction tank 201. At the same time, when the reaction tank 201 rotates, the fixed ring 7 and the driving block 8 at both ends of the reaction tank 201 are also driven to rotate. When the driving block 8 rotates, it can intermittently drive the pressure block 6 to lift. When the two groups of pressure blocks 6 are lifted under pressure, they simultaneously drive the lifting plate 4 to rise relative to the blocking plate 3. When the lifting plate 4 rises, the lifting and stirring mechanism 9 installed on the lifting plate 4 will rise synchronously. Since the rotating shaft 902, the stirring cylinder 909, the inclined stirring blade 910, and the vertical stirring blade 911 of the lifting and stirring mechanism 9 are located in the second batch of materials inside the feeding rack 14, the lifting process can lift and disperse the second batch of materials. Meanwhile, when the rotating shaft 902 rises, the gear 903 fixed on the rotating shaft 902 meshes with the toothed plate 904 fixedly installed, and in the meshing state of the gear 903 and the toothed plate 904 and when rising, the gear 903 can drive the rotating shaft 902 to rotate, that is, the rotating shaft 902 can rotate while rising at this time, so that the inclined stirring blade 910 and the vertical stirring blade 911 can better fully disperse the second batch of materials in the feeding rack 14; When one group of the driving blocks 8 extrude the pressure-receiving blocks 6 to the topmost position, the driving blocks 8 are separated from the pressure-receiving blocks 6 at this time, and the lifting plate 4 is lowered relative to the closing block 3 and the main body 1 under the action of the elastic sheet 10, that is, at this time, the lifting stirring mechanism 9 is lowered and the rotating shaft 902 is reversely rotated simultaneously; As known from the above, the reaction tank 201 is rotated to synchronously drive the fixed ring 7 and the driving blocks 8 to rotate, the driving blocks 8 are intermittently contacted with the pressure-receiving blocks 6, the elastic sheet 10 is reset, the lifting plate 4 and the lifting stirring mechanism 9 are reciprocatingly lifted and lowered, the lifting stirring mechanism 9 is synchronously reversely rotated through the meshing of the gear 903 and the toothed plate 904 during the lifting and lowering, and the inclined stirring blade 910 and the vertical stirring blade 911 are driven to perform a composite action on the materials; The lifting action lifts and lowers the second batch of materials to disperse, the rotating action cooperatively stirs the materials through the two kinds of blades, breaks the material agglomeration, makes the material particles more uniformly distributed, avoids local accumulation, and through the reciprocating lifting and rotating composite processing, preheats the materials entering the reaction tank 201, helps to improve the efficiency and effect of subsequent high-temperature and high-pressure sterilization processes, and reduces the problem of incomplete local processing due to uneven materials.
