DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0032] Embodiment 1

[0033] like Figures 1 to 8 As shown, a feed stewing process comprises the following steps:

[0034] S1: The material is sent into the stewing tank 3 through the air lock 1 and the material distributor 2;

[0035] S2: the material is stewed in the stewing tank 3 to a set degree of maturity;

[0036] S3: The materials are sent to the temporary storage bin through the first opening and closing mechanism for temporary storage;

[0037] S4: The material is sent to the next process through the second opening and closing mechanism.

[0038] The next process specifically refers to cooling, that is, the second opening and closing mechanism is arranged between the temporary storage bin and the cooler.

[0039] The air lock 1 preferably adopts an air lock 1 without air vents to prevent heat loss in the stewing pot 3. The sparger 2 is located below the air lock 1. The sparger 2 adopts a rotating chute to evenly distribute the feed in the stewing pot 3. Specifically, the sparger 2 is provided with a chute that can rotate around a vertical axis. The length direction of the chute extends spirally along the vertical axis, and the chute is driven by a motor. The upper end of the chute is located at the output end of the air lock 1, and the lower end is connected to the stewing pot 3.

[0040] A feed stewing process of the present embodiment is connected to the previous process through the air lock 1. The previous process is specifically a granulation process, which can not only realize the feeding of feed, but also avoid the upper end of the stewing tank 3 being connected to the outside to affect the temperature and humidity during the maturation process. In addition, by providing a material distributor 2, the feed can be evenly distributed in the stewing tank 3, ensuring that the feed in each area of ​​the stewing tank 3 is fully matured. The stewing tank 3 and the temporary storage bin are separated by the first opening and closing mechanism, which is convenient for the stewing tank 3 and the temporary storage bin to function independently. Therefore, as a whole, the present invention can ensure uniform feeding, complete maturation and stable quality.

[0041] Specifically, a heating interlayer is provided in the side wall of the stewing pot 3, which can be specifically set as a double-layer stainless steel structure. A steam heat dissipation pipe is provided in the heating interlayer for heating the stewing pot 3. During operation, hot steam is introduced through the steam heat dissipation pipe, and then the side wall of the stewing pot 3 is evenly heated through metal heat conduction and air heat conduction, thereby making the feed in the stewing pot 3 evenly heated. In order to maintain the heat of the stewing pot 3, a heat-insulating surface layer is provided on the surface of the stewing pot 3.

[0042] The specific size (such as inner diameter, height) of the stewing pot 3 can be set as needed, for example, according to the volume required for the hourly output of the granulator, generally set to twice the mass and hourly output.

[0043] The post-stewing process equipment also includes a control device, which includes a number of thermometers, hygrometers, digital pressure gauges, etc. arranged on the stewing pot 3 in the vertical direction, as well as an air inlet valve and an air release valve arranged on the steam heat dissipation pipe, so as to control the steam flow of the steam heat dissipation pipe through the detection values ​​of the thermometer, hygrometer, and pressure value. The thermometer, hygrometer, pressure gauge, and material level meter are preferably set as plug-in dry type digital devices, which are set at the upper, middle, and lower positions of the stewing pot 3 through perforations. During operation, the control device opens the air release valve nozzle to release high-temperature steam and replenish high-temperature steam when the temperature in the stewing pot 3 detected is higher than the control temperature, thereby realizing the control of temperature and humidity.

[0044] The stew pot 3 is provided with a thermometer, a hygrometer, a digital pressure gauge and a material level meter, and the steam heat dissipation pipe is provided with an air inlet valve and an air release valve for controlling its flow rate, so as to control the steam flow rate of the steam heat dissipation pipe through the detection values ​​of the thermometer, the hygrometer and the digital pressure gauge, and detect the distance of the material level from the first opening and closing mechanism through the material level meter. The thermometer, the hygrometer, the digital pressure gauge and the material level meter are preferably set as plug-in dry type digital devices, which are set at the upper, middle and lower positions of the stew pot 3 through perforations. During the working process, when the temperature in the stew pot 3 detected by each device is higher than the control temperature, the air release valve nozzle is opened to release high-temperature steam and replenish high-temperature steam, thereby realizing the control of temperature and humidity.

[0045] Further, the first opening and closing mechanism includes a first driving cylinder 4, a linkage assembly and a leak opening and closing assembly, the leak opening and closing assembly includes a plurality of closing units 5, the plurality of closing units 5 are arranged in a straight line to form a closing surface, the closing unit 5 includes a horizontally arranged rotating shaft 6 and a sealing plate 8, the two ends of the rotating shaft 6 are installed on the side walls of the stewing pot 3, the sealing plate 8 has a root end and a tip end in relative positions, the root end is connected to the rotating shaft 6, the linkage assembly includes a connecting rod 12, a driving rod 13 and a plurality of swing arms 14, one end of the connecting rod 12 is rotatably connected to the piston rod of the first driving cylinder 4, and the other end is rotatably connected to the driving rod 13, the plurality of swing arms 14 are arranged one-to-one with the plurality of closing units 5, one end of the swing arm 14 is connected to the rotating shaft 6, and the other end is rotatably connected to the driving rod 13. During use, when the multiple sealing plates 8 are in a horizontal posture, the passage between the stewing tank 3 and the temporary storage bin is closed. When the sealing plates 8 are in a non-horizontal posture, a gap is generated between two adjacent closed units 5 in the multiple closed units 5, and the material can enter the temporary storage bin from the stewing tank 3 through the gap, so that the passage between the stewing tank 3 and the temporary storage bin can be opened and closed by controlling the posture of the sealing plates 8. The posture of the sealing plates 8 is achieved by the rotation of the rotating shaft 6, and the rotation of the rotating shaft 6 is achieved by the driving of the first driving cylinder 4. When the first driving cylinder 4 is actuated, it drives the rotating shaft 6 to rotate, thereby achieving the adjustment of the posture of the sealing plates 8. Under such a structural setting, multiple closed units 5 move synchronously, so that the tank and the temporary storage bin can be quickly opened and closed, which can effectively save time and achieve quick opening and closing when it is suitable for a larger passage between the stewing tank 3 and the temporary storage bin. At the same time, the swing arm 14 and the driving rod 13 can be arranged on the outside of the stewing tank 3, which will not affect the airtightness of the stewing tank 3 and has strong practicality. When the driving rod 13 and the swing arm 14 are arranged on the outside of the stewing tank 3, the rotating shaft 6 is required to pass through the side wall of the stewing tank 3 and be connected with the swing arm 14.

[0046] The closed unit 5 also includes a vibration generating assembly, which includes a driving belt 15, a return spring 16, a fixed block 17 and a plurality of vibration members 18, wherein the vibration member 18 includes a fixed rod 19, a pulley 20 and an eccentric weight 21. A vibration generating chamber 9 is provided inside the tip of the sealing plate 8, wherein the plurality of vibration members 18 are arranged in a straight line in the generating chamber, the fixed rod 19 is fixed on the wall of the vibration generating chamber 9, the pulley 20 is rotatably arranged on the fixed rod 19, the eccentric weight 21 is fixedly connected to the pulley 20, the return spring 16 is fixedly installed in the vibration generating chamber 9, one end of the driving belt 15 is connected to the return spring 16, and the other end passes through the pulley 20 of the plurality of vibration members 18 and then passes through the top of the vibration generating chamber 9, and is connected to the fixed block 17, and the fixed block 17 is fixed on the inner wall of the stew pot 3. Under such a structural setting, since one end of the driving belt 15 is fixedly connected to the fixed block 17, when the sealing plate 8 moves, the driving belt 15 will move relative to the pulley 20. During such movement, the pulley 20 is driven to rotate, thereby driving the eccentric hammer 21 to rotate. During the rotation, the eccentric hammer 21 generates vibration due to the action of its eccentric force, that is, the sealing plate 8 will generate vibration during the upward or downward movement, thereby being able to shake off the material adhered to the sealing plate 8 or the material blocking the stewing tank 3 and the temporary storage bin, so that the material can smoothly enter the temporary storage bin from the stewing tank 3. Furthermore, when the sealing plate 8 continues to reciprocate, the vibration it generates is continuous, thereby being able to continuously generate vibration and shaking-off effects, thereby achieving rapid transfer of materials and improving work efficiency.

[0047] Furthermore, the fixing rod 19 is provided with a first thread, the pulley 20 is provided with a second thread matching the first thread, a distance sensor 10 is provided at the bottom of the vibration generating chamber 9, and the distance sensor 10 is arranged corresponding to the position of an eccentric hammer 21, and has two states of being blocked and not blocked during the movement of the corresponding eccentric hammer 21, a plurality of positioning blocks 11 are provided at the tip of the sealing plate 8, and a plurality of positioning grooves 7 corresponding to the plurality of positioning blocks 11 are provided on the rotating shaft 6, the closing unit 5 also includes a movable plate 22, an electromagnet 23 and a holding spring 24, the movable plate 22 is slidably arranged at the bottom of the rotating shaft 6, the movable plate 22 is provided with a plurality of through openings 28 corresponding to the plurality of positioning grooves 7, the holding spring 24 and the electromagnet 23 are arranged at the bottom of the rotating shaft 6, the holding spring 24 is connected to one end of the movable plate 22, and the electromagnet 23 acts on the other end of the movable plate 22. Due to the cooperation between the first thread and the second thread, when the driving belt 15 drives the belt 15 wheel to rotate, the eccentric weight 21 will move relative to the fixed rod 19, specifically, along the axial direction of the fixed rod 19. Therefore, during the movement of the eccentric weight 21, the distance sensor 10 has two states: blocked and unblocked. By judging the blocking state of the distance sensor 10, the real-time position of the sealing plate 8 can be analyzed. Under such a premise, the control of the movable plate 22 can be achieved. Specifically, in this embodiment, when the distance sensor 10 switches from the unblocked state to the blocked state, the posture of the sealing plate 8 is judged to be in the horizontal state, and the positioning block 11 on the sealing plate 8 enters the positioning groove 7 of the adjacent closing unit 5 to control the electromagnet 23 is energized, so that the movable plate 22 is close to the electromagnet 23, thereby causing the position between the through hole 28 and the positioning slot 7 to be misaligned, and the movable plate 22 closes the positioning slot 7. In this state, if there is no control signal, the movable plate 22 will not be able to move downward due to the obstruction of the movable plate 22, thereby locking the posture of the closing plate 8. When it is necessary to move the closing plate 8 downward, an electrical signal is sent to cut off the power to the electromagnet 23. Under the action of the holding spring 24, the movable plate 22 moves in the direction close to the holding spring 24, so that the positions of the through hole 28 and the positioning slot 7 correspond to each other, and then the first driving cylinder 4 is started to rotate the rotating shaft 6. At this time, the positioning block 11 can pass through the positioning slot 7 through the through hole 28, and the closing plate 8 can move downward.

[0048] The second opening and closing mechanism includes a second driving cylinder 26 and a sealing door 25. The sealing door 25 is arranged between the temporary storage bin and the cooler and is connected to the second driving cylinder 26. The sealing door 25 is driven by the second driving cylinder 26 to move, so as to realize the opening and closing of the passage between the temporary storage bin and the cooler. The temporary storage bin is arranged in a funnel shape. Since the passage between the temporary storage bin and the cooler is small, the cooperation of the second driving cylinder 26 and the damper can realize rapid opening and closing, which saves the action time and effectively ensures the stability of the structure.

[0049] It is not difficult to understand that to realize the above-mentioned control process, a control device is required. The control device has various electronic components electrically connected to realize the control process. Such a control device is a commonly used control device in the prior art. Its working process is realized through a set specific program. Those skilled in the art can implement such a solution based on their technical reserves.
