Description

Technical Field

[0001] The invention relates to the technical field of steaming equipment, in particular to a material steaming device with high thermal efficiency. Background Art

[0002] Steaming (also known as wet heat treatment) is one of the commonly used treatment methods for the harmless treatment of animal carcasses. It is widely used in the treatment of dead livestock and poultry, slaughter residues, etc. It is a method of treating animal carcasses and related animal products under the action of dry heat, pressure or high temperature and pressure by introducing high-temperature saturated steam into the container interlayer or container in a closed high-pressure container. This method uses high-temperature and high-pressure steam to heat, sterilize and degrade the tissue of animal carcasses.

[0003] After searching, the invention patent with publication number CN103431753A discloses a material cooking device and method, which realizes the automation of material cooking, ensures that the gas entering the sealed container meets the preset pressure value, ensures work efficiency, and improves work quality.

[0004] It is mainly aimed at the steaming treatment of ordinary materials, and has failed to effectively solve the problems of incomplete deep sterilization and low thermal efficiency in the steaming of dead animal carcasses. Currently, traditional animal carcass steaming devices are mostly composed of a fixed cylindrical tank and a stirring device arranged inside the tank. During operation, the carcasses in the tank are heated by continuously injecting high-temperature and high-pressure steam. However, due to the large size of animal carcasses and the dense and complex tissue structure, it is difficult for steam to penetrate into the deep tissue area in a short time, resulting in the temperature of some tissue centers failing to meet the sterilization standards. There are risks such as incomplete inactivation of pathogens and residual viruses, which bring hidden dangers to subsequent resource processing and environmental safety. In addition, in the steaming system for harmless treatment of animal carcasses, although the filtering structure at the discharge port can effectively intercept large pieces of unsoftened materials and foreign matter and protect downstream equipment, it is easy to get clogged due to high viscosity, fat, tissue blocks, etc.; blockage will bring problems such as poor discharge, equipment shutdown, and frequent manual cleaning.

[0018] A further technical improvement of the present invention is that a lifting unit is installed on the upper end surface of the blocking seat 1, and the fixed end of the lifting unit is fixed to the surface of the feeding dragon.

[0019] A further technical improvement of the present invention is that two arc-shaped supports are provided at the bottom of the tank body, and the gap length between the two arc-shaped supports is greater than the sum of the lengths of the two sealing seats and the feed port.

[0020] A further technical improvement of the present invention is that support frames are installed on both sides of the tank body, a driving motor 2 for driving the spiral auger to rotate is installed on the support frame on one side, and a driving motor 1 for driving the tank body to rotate is installed on the support frame on the other side.

[0021] A further technical improvement of the present invention is that a filter unit is provided inside the discharge port, and a cleaning unit for blowing away residual filter residue in the filter unit is provided below the filter unit.

When loading, the docking port slides vertically downward and passes through the two opened clamping frames, and then contacts the feed port. The clamping cylinder drives the two clamping frames closer to each other. The clamping frames cover the feed port and the outside of the docking port. The bottom surface of the inner cavity of the clamping frame contacts the lower end surface of the feed port flange. Then, the armature in the electromagnet is energized to push the pressure plate to slide within the clamping frame and contact the upper end surface of the docking port flange, thereby completing the sealing installation of the feed port and the docking port.

When the filter unit is detected to be clogged, the control system drives the tank body to rotate so that the discharge port is at the top, and gravity is used to automatically cause some filter residue to fall off. The moving plate then slides and drives the second abutment into the moving plate to make way for subsequent actions. Immediately afterwards, the first abutment rises and drives the contact piece with several air holes to rub against the surface of the filter unit to scrape off the filter residue. Clean gas is simultaneously introduced to purge the surface of the filter unit through the flow cavity and air holes, completely removing the filter residue that is difficult to scrape off.

[0030] 3. After the loading is completed, the upper and lower blocking plates are closed to prevent odor leakage and cross contamination. At the same time, the interface moves upward under the push of the lifting unit, dynamically avoids interference with the rotation of the tank, and adapts to continuous automatic feeding.

[0040] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0041] See also Figure 1-Figure 7 As shown, the present invention provides a high thermal efficiency material cooking device, comprising a rotatable tank body 1, wherein a spiral auger 19 rotating in stages is rotatably installed inside the tank body 1;

[0042] During the heating and softening stage, the tank body 1 rotates clockwise while the auger 19 rotates counterclockwise, which strengthens the turning and mixing of the materials, accelerates the heating and softening, and enhances the stirring and mixing;

[0043] During the discharge phase, the tank body 1 and the auger 19 rotate in the same direction to accelerate the discharge;

[0044] A feed port 7 is provided in the middle of the top surface of the tank body 1, and a discharge port 3 is provided in the middle of the bottom surface of the tank body 1;

[0045] The top of the feed port 7 is connected to a docking port 6 that slides vertically along the discharge direction of the loading dragon. A blocking seat 5 is provided on the outside of the docking port 6. An upper blocking plate 17 is provided inside the blocking seat 5 to block the inside of the docking port 6.

[0046] Two blocking seats 8 are symmetrically provided on the outside of the feed port 7, and a lower blocking plate 10 is slidably provided inside the blocking seat 8 to block the feed port 7, and a crimping unit is provided on the top end of the blocking seat 8 to seal the feed port 7 and the docking port 6;

[0047] The crimping unit includes a clamping cylinder 9, the two driving ends of the clamping cylinder 9 are respectively connected to a clamping frame 14 of a semi-annular structure, the internal limit sliding of the clamping frame 14 is provided with a pressure plate 15 in contact with the end surface of the docking port 6, and the top surface of the clamping frame 14 is installed with an electromagnet 16 that pushes the pressure plate 15;

[0048] In the initial state, the semi-annular clamping frames 14 on both sides are in the open state;

[0049] During use, the docking port 6 slides vertically downward and passes through the two opened clamping frames 14 to contact the feed port 7. Then the clamping cylinder 9 drives the two clamping frames 14 to approach each other. The clamping frames 14 cover the outside of the feed port 7 and the docking port 6. In this process, the bottom surface of the inner cavity of the clamping frame 14 contacts the lower end surface of the flange of the feed port 7. Then the armature in the electromagnet 16 is energized to push the pressure plate 15 to slide within the clamping frame 14 and contact the upper end surface of the flange of the docking port 6, thereby completing the sealing installation of the feed port 7 and the docking port 6. The entire sealing action is completed automatically without manual adjustment, and is suitable for high-frequency operation requirements of material crushing and automatic conveying.

[0050] The material is crushed outside the tank body 1, without the need for crushing inside the tank body 1, to avoid large pieces of tissue inside the tank from hindering heat penetration, so that high-temperature steam can penetrate deep tissue areas in a short time, greatly improving sterilization efficiency and uniformity;

[0051] After the material is crushed, it is transported by the feeding auger. Since it is connected to the feed port 7, it ensures smooth entry of the material and continuous feeding. At the same time, there will be no diffusion or leakage of odor.

[0052] When the material enters, the upper blocking plate 17 and the lower blocking plate 10 are both in the open state;

[0053] After the loading is completed, the upper blocking plate 17 and the lower blocking plate 10 are closed, and the docking port 6 moves upward to avoid interference with the feed port 7 following the rotation, thus achieving dynamic protection and sealing double insurance;

[0054] When the tank body 1 and the auger 19 rotate, the tank body 1 rotates clockwise while the auger 19 rotates counterclockwise, thereby strengthening the turning and mixing of the materials, accelerating the heating and softening, and enhancing the stirring and mixing;

[0055] Afterwards, the tank body 1 and the spiral auger 19 rotate in the same direction, quickly and cooperatively promoting the discharge of materials, with less residue and high efficiency.

[0056] See Figure 2 and Figure 3 As shown, a sliding groove 13 is installed on the same outer side of the blocking seat 2 8 and the blocking seat 1 5, and two sets of drive units are installed on the docking port 6 and the feed port 7. Each set of drive units includes two screws 11 driven by a dual-axis motor to improve the synchronization and thrust of motion control. The outer side of each screw 11 is threadedly sleeved with a push block 12 that slides along the sliding groove 13. The two sets of push blocks 12 are respectively connected to the upper blocking plate 17 and the lower blocking plate 10;

[0057] The upper end surface of the blocking seat 5 is installed with a lifting unit 4, and the fixed end of the lifting unit 4 is fixed to the surface of the feeding dragon;

[0058] The upper blocking plate 17 and the lower blocking plate 10 are both semicircular structures;

[0059] When driving the corresponding upper blocking plate 17 and lower blocking plate 10 to move, the upper blocking plate 17 and lower blocking plate 10 drive the push block 12 to move in the corresponding sliding groove 13 in a limited and guided manner, ensuring that the blocking plate slides linearly, smoothly and accurately to the sealing position.

[0060] See Figure 1 and Figure 2 As shown, two arc-shaped supports 2 are provided at the bottom of the tank body 1, and the gap length between the two arc-shaped supports 2 is greater than the sum of the lengths of the two blocking seats 8 and the feed port 7;

[0061] It ensures that during the rotation or loading and unloading process of the tank body 1, the feed port 7 and the blocking seat 2 8 can avoid smoothly and will not interfere with or collide with the arc support 2, which is beneficial to the overall structural safety and maintenance operation of the equipment.

[0062] See Figure 1 and Figure 5 As shown, support frames are installed on both sides of the tank body 1. A driving motor 20 for driving the spiral auger 19 to rotate is installed on the support frame on one side, and a driving motor 18 for driving the tank body 1 to rotate is installed on the support frame on the other side.

[0063] See Figure 6 As shown, a filter unit 22 is provided inside the discharge port 3 for intercepting large particles, insufficiently softened residues, foreign matter, etc. during the material discharge process to prevent downstream equipment from being blocked or process abnormalities. A cleaning unit for blowing away residual filter residues in the filter unit 22 is provided below the filter unit 22; ensuring the smooth flow of the filter unit 22, reducing the frequency of manual maintenance, and improving system stability and operating efficiency.

[0064] See Figure 7 As shown, the cleaning unit includes a cleaning chamber 23 communicating with the discharge port 3, a moving plate 32 is slidably provided inside the cleaning chamber 23, a notch is provided at the bottom of the moving plate 32, and an automatically rebounding abutment member 2 30 and an abutment member 1 27 are sequentially provided in the notch;

[0065] The upper surface of the moving plate 32 is provided with a reset cavity 25, the outer portion of the abutment member 27 is sleeved with a spring 26, and the upper end surface of the abutment member 27 is provided with a contact member 24 that is in sliding contact with the surface of the filter unit 22;

[0066] A fixing member 31 with an inclined end is provided inside the discharge port 3 below the filter unit 22. The fixing member 31 abuts against the second abutment member 30 and the first abutment member 27 in sequence. Both sides of the fixing member 31 and the inner wall of the discharge port 3 are provided with downwardly inclined openings for guiding the filter residue to be discharged smoothly.

[0067] The upper surface of the contact member 24 is provided with a plurality of air holes, and the interior of the abutting member 27 is provided with a flow cavity 28 communicating with the plurality of air holes, and one side of the abutting member 27 is softly connected to an air pipe 29 connected to an external air source;

[0068] In the initial state, the moving plate 32 is located inside the cleaning chamber 23, and the second abutment member 30 is in contact with the end surface of the fixing member 31. At this time, the moving plate 32 is relatively sealed. When the filter unit 22 is blocked, the tank body 1 rotates to the top. At this time, the discharge port 3 is located at the top. Under the action of gravity, a part of it will fall down, realizing the first step of physical unloading.

[0069] Then the moving plate 32 slides, driving the second abutting member 30 to abut against the fixed member 31. At this time, the second abutting member 30 is hidden in the moving plate 32, making room for the subsequent scraping action.

[0070] Then, the abutting member 27 comes into contact with the fixing member 31 again, causing the abutting member 27 to drive the contact member 24 upward. At this time, the spring 26 elastically stretches in the reset chamber 25. Due to the frictional contact between the contact member 24 and the filter unit 22, the filter residue adhering to the filter unit 22 is scraped off. Then, the clean gas enters through the air pipe 29, passes through the circulation chamber 28, and is blown out from the multiple air holes, performing multi-point synchronous cleaning on the surface and gaps of the filter unit 22 to remove residual and difficult-to-scrape fine filter residue.

[0071] After the action is completed, the moving plate 32 is reset, and each component automatically returns to its original position under the action of the spring 26 and the reset chamber 25, and the cleaning unit 22 automatically returns to its initial sealing state, ensuring long-term and efficient operation of the equipment;

[0072] The use of gravity, mechanical and pneumatic multi-stage coordination can improve the shedding and thoroughness of filter residue removal, reduce the frequency of shutdown and manual cleaning, and scraping and air blowing are carried out in steps to take into account the cleaning of large particles and fine impurities.

[0073] See Figure 6 As shown, a steam jacket 21 is provided inside the tank body 1, and a passage for steam entry is provided on the inner wall of the tank body 1 controlled by a pneumatic valve. The steam jacket 21 is arranged around the inner wall of the tank body 1 to indirectly heat the material in the tank body 1, thereby achieving efficient and uniform heating and heat preservation.

[0074] The pneumatic valve is linked to the automatic control system and can automatically adjust according to the feedback signal from the temperature sensor. The steam flow rate is intelligently controlled by the pneumatic valve to achieve precise heating and insulation in different process stages, reduce ineffective energy consumption and improve thermal efficiency.

[0075] When the present invention is in use, the material is crushed outside the tank body 1 to ensure uniform particle size, facilitate steam penetration and rapid temperature rise, avoid large pieces of tissue in the tank body 1 from hindering heat penetration, and allow high-temperature steam to penetrate into deep tissue areas in a short time, greatly improving sterilization efficiency and uniformity. When loading, the docking port 6 slides vertically downward, and after passing through the two opened clamping frames 14, it comes into contact with the feed port 7. The clamping cylinder 9 drives the two clamping frames 14 to approach each other. The clamping frame 14 covers the feed port 7 and the outside of the docking port 6. The bottom surface of the inner cavity of the clamping frame 14 contacts the lower end surface of the flange of the feed port 7. Then, the armature in the electromagnet 16 is energized to push the pressure plate 15 to slide within the clamping frame 14 to limit the upper end surface of the flange of the docking port 6, thereby completing the sealing installation of the feed port 7 and the docking port 6. The entire sealing action is automatically completed, and the rotation direction of the tank body 1 and the spiral auger 19 is staged;

[0076] By setting up the cleaning unit, in the initial state, the moving plate 32 is located inside the cleaning chamber 23, and a seal is achieved by the contact between the second abutment member 30 and the end face of the fixing member 31; when it is detected that the filter unit 22 is blocked, the control system drives the tank body 1 to rotate so that the discharge port 3 is located at the top, and gravity is used to automatically cause some filter residue to fall off; then the moving plate 32 slides and drives the second abutment member 30 to enter the moving plate 32 to make way for subsequent actions; then the first abutment member 27 rises and drives the contact member 24 with a plurality of air holes to rub against the surface of the filter unit to scrape off the filter residue, and clean gas is simultaneously introduced to purge the surface of the filter unit 22 through the flow cavity 28 and the air holes, and the filter residue that is difficult to scrape off is completely removed;

[0077] After the loading is completed, the upper blocking plate 17 and the lower blocking plate 10 are closed to prevent odor leakage and cross contamination. At the same time, the docking port 6 moves upward under the push of the lifting unit 4, dynamically avoiding interference with the rotation of the tank body 1 to adapt to continuous automatic feeding.

[0078] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
