Description

Technical Field

[0001] The invention relates to the technical field of gas separation, and in particular to a method for preparing pig feed fermentation with deodorizing effect. Background Art

[0002] In the production process of pig feed, some fermentation agents or additives are often used to improve the taste and nutritional value of feed. However, these fermentation agents or additives sometimes produce special odors, which affect the appetite and digestion and absorption of animals. In order to solve this problem, fermentation deodorization equipment is used in feed processing to improve the taste of feed by separating the odorous gases produced during the fermentation process. However, the deodorization equipment in the prior art usually uses a static activated carbon device, which has limitations in the contact efficiency between gas and activated carbon particles. When the activated carbon is saturated with adsorption, it usually needs to be replaced manually, and the whole process is cumbersome and time-consuming. In addition, the replacement frequency of activated carbon is high, which invisibly increases the burden of operation and maintenance. Chinese patent application CN117983019A discloses a fermentation deodorization device for feed processing, which includes a filter box shell, one side of which is plugged with multiple activated carbon placement drawers. The device is also equipped with a removal mechanism, including a tooth plate, a connecting frame, a plug, a drive assembly and a locking assembly. Through the cooperation of these components, multiple fixed plates and activated carbon placement drawers can be synchronously detached from the filter box shell. When the drive assembly is started, the tooth plate drives the activated carbon placement drawers out of the filter box shell and moves them to the transport rack. This design avoids the tedious process of manually disassembling and loading the activated carbon placement drawers one by one, making the operation easier and significantly improving the replacement efficiency, thereby accelerating the entire deodorization process. However, in actual applications, due to factors such as the movement of fluids and differences in the performance of activated carbon, the saturation time of activated carbon is inconsistent. Considering that there are multiple activated carbons in the equipment when they are in use, the saturation time of each activated carbon will not occur at the same time due to differences in gas adsorption, so that the simultaneous replacement of activated carbon will lead to the inability to maximize the use of activated carbon. Frequent replacement will increase the burden on staff and production. In addition, the desorption method in the prior art is mostly to uniformly heat and regenerate the entire equipment or a large number of activated carbon cylinders. This method is prone to energy waste and limited regeneration effect, especially when the adsorption effect is significantly different. Summary of the invention

[0003] In view of the above problems, a method for preparing pig feed fermentation with a deodorizing effect is provided, by providing an activated carbon cartridge with a cylindrical structure and a granular filler inside thereof, and coordinating the synchronous rotation of a rotating frame, the contact area and contact frequency between the gas and the activated carbon are significantly increased, and the deodorizing efficiency is improved. By using a receiving frame in coordination with the rotating frame, after the adsorption capacity of the activated carbon decreases, the activated carbon cartridge can be automatically moved from the rotating frame to the top and naturally fall onto the receiving frame by gravity, and the activated carbon cartridge can be replaced without human intervention. In this way, the cumbersome manual disassembly process in the prior art is avoided, the maintenance efficiency of the equipment is significantly improved, and the labor burden of the operators is reduced.

[0004] In order to solve the problems of the prior art, the present invention provides a method for preparing pig feed fermentation with a deodorizing effect.

[0009] S5. After desorption is completed, the rotating frame continues to rotate, and the empty space without the activated carbon cartridge is transferred to the bottom of the filter box. The rotation is stopped, and the receiving frame is rotated to make the activated carbon cartridge lose its support and fall to the bottom of the filter box. The activated carbon cartridge is re-clamped by the clamping assembly on the rotating frame to resume its use.

[0010] S6. If the activated carbon cartridge cannot recover its deodorizing ability after desorption, repeat step S3, and move the activated carbon cartridge out of the filter box along the axis of the filter box by pulling the receiving frame, and replace it with a new activated carbon cartridge.

[0011] Preferably, the rotating frame is provided with channels which are the same in number and correspond one to one to the activated carbon cartridge, and two clamping assemblies are respectively arranged on the two rotating frames in a mirror-symmetrical state, the clamping assembly includes a connecting shaft which can slide along the axial direction of the channel, a limiting plate is provided on the end of the connecting shaft away from the channel, an elastic member is provided between the limiting plate and the channel, and driving assemblies for synchronously driving the two clamping assemblies to clamp or release the activated carbon cartridge are provided on the top and bottom of the filter box.

[0019] Preferably, both the rotating frame and the supporting frame are provided with angle sensors for monitoring their rotation angles.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention significantly increases the contact area and frequency between gas and activated carbon by setting up an activated carbon cartridge with a cylindrical structure and its internal granular filler, in coordination with the synchronous rotation of a rotating frame. Compared with the traditional static structure, the deodorization efficiency is greatly improved. At the same time, the slidable and rotatable receiving frame is used in coordination with the rotating frame. After the adsorption capacity of the activated carbon decreases, the activated carbon cartridge can be automatically moved from the rotating frame to the top and naturally fall onto the receiving frame by gravity. The activated carbon cartridge can be replaced without human intervention. In this way, the cumbersome manual disassembly process in the prior art is avoided, the maintenance efficiency of the equipment is significantly improved, and the labor burden of the operators is reduced.

[0022] 2. The present invention arranges the connecting shaft and the valve core. When the clamping assembly clamps the activated carbon cartridge, the gas can smoothly enter the channel from the first valve port and enter the activated carbon cartridge through the connecting shaft. When the activated carbon cartridge needs to be loosened, the movement of the connecting shaft will drive the valve core to close the first valve port to ensure that the gas will not leak during operation. At the same time, after the power of the driving assembly is lost, the elastic part will move the valve core to the second valve port to further ensure that the gas can only be transmitted through the activated carbon cartridge. This arrangement improves the sealing performance of the equipment, avoids gas leakage due to operating errors or system stagnation, and ensures the operating safety and stability of the equipment.

[0023] 3. The present invention arranges a first guide plate on the limit plate, which cooperates with the second guide plates at the top and bottom of the support frame to ensure that the activated carbon cartridge always maintains a stable posture during the clamping, rotation or desorption process, avoiding tilting or deviation. Through the arrangement of the first guide plate and the second guide plate, the activated carbon cartridge can be accurately guided to the specified position during the replacement or desorption process, which not only reduces the friction and collision with other components, extends the service life of the activated carbon cartridge and the equipment, but also further improves the operating accuracy of the entire device. At the same time, the desorption mechanism is centrally arranged in the interlayer of the equipment, and desorption is carried out by local heating, which makes the activated carbon regeneration process more efficient, effectively extends the service life of the activated carbon, reduces the replacement frequency, and reduces the operating cost of the equipment.

DETAILED DESCRIPTION

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figures 1 to 7 As shown: A method for preparing pig feed fermentation with deodorizing effect, the device used in the preparation method comprises a filter box 1 with a horizontal axis, a support frame 11 is arranged on the axis of the filter box 1, a receiving frame 111 which can slide along the axis of the filter box 1 is arranged on the support frame 11, and the receiving frame 111 is rotatably arranged on the support frame 11; an air inlet cavity 12 and an air outlet cavity 13 are respectively arranged at both ends of the filter box 1, and a rotatable rotating frame 2 is respectively arranged on the air inlet cavity 12 and the air outlet cavity 13; the rotating frame 2 is provided with a plurality of activated carbon cartridges 22 which are equidistantly distributed around its axis, and the two rotating frames 2 are both provided with a clamping assembly 21 which can clamp the two ends of the activated carbon cartridge 22; a desorption mechanism 15 for heating the activated carbon cartridge 22 is arranged in the support frame 11; the preparation method comprises the following steps:

[0041] S1. The gas generated in the fermentation equipment is introduced into the air inlet cavity 12 of the filter box 1, and the gas is guided to flow through the activated carbon cylinder 22 on the rotating frame 2 through the air inlet cavity 12, and the activated carbon cylinder 22 is used to deodorize the gas.

[0042] S2. The rotating frame 2 rotates to drive the multiple activated carbon cylinders 22 to rotate synchronously, so that the granular fillers inside the activated carbon cylinders 22 move accordingly, thereby increasing the contact area between the activated carbon and the gas and improving the deodorization effect;

[0043] S3. When the deodorizing ability of the activated carbon decreases, continue to rotate the rotating frame 2 until the activated carbon cartridge 22 with reduced deodorizing effect moves to the top of the filter box 1, stop the rotation of the rotating frame 2, and the two clamping components 21 release the clamping of the activated carbon cartridge 22, so that the activated carbon cartridge 22 falls into the receiving frame 111 located on the axis of the filter box 1.

[0044] S4, starting the desorption mechanism 15 inside the support frame 11, heating the activated carbon cartridge 22 for desorption, and restoring the deodorization ability of the activated carbon cartridge 22.

[0045] S5. After desorption is completed, the rotating frame 2 continues to rotate, and the empty space where the activated carbon cartridge 22 is lost is transferred to the bottom of the filter box 1. The rotation is stopped, and the activated carbon cartridge 22 loses its support and falls to the bottom of the filter box 1 by rotating the receiving frame 111. The activated carbon cartridge 22 is re-clamped by the clamping assembly 21 on the rotating frame 2 to resume its use.

[0046] S6. If the activated carbon cartridge 22 cannot recover its deodorizing ability after desorption, repeat step S3, and move the activated carbon cartridge 22 out of the filter box 1 along the axial direction of the filter box 1 by pulling the receiving frame 111, and replace it with a new activated carbon cartridge 22.

[0047] The activated carbon cartridge 22 is a cylindrical structure, and the two ends of the activated carbon cartridge 22 are respectively arranged at the connection ports. A plurality of granular fillers are arranged in the activated carbon cartridge 22. By installing a plurality of activated carbon cartridges 22 on the rotating frame 2 and allowing the activated carbon cartridges 22 to rotate synchronously with the rotating frame 2, the granular fillers inside the activated carbon cartridge 22 can move with the rotation, which greatly increases the contact area and contact frequency between the gas and the activated carbon. Compared with the activated carbon device with a traditional static structure, the equipment can improve the odor generated during the preparation of pig feed, and the deodorization efficiency is improved; the design of using a sliding receiving frame 111 and a rotatable rotating frame 2 in combination can automatically move the activated carbon cartridge 22 from the rotating frame to the top and naturally fall to the receiving frame by gravity after the adsorption capacity of the activated carbon decreases. Rack 111, compared with the prior art, this method avoids the tedious process of manually disassembling the activated carbon cartridge 22, and by setting a replacement and desorption point in the filter box 1, the activated carbon cartridge 22 can be concentrated in a single position for maintenance and regeneration. This centralized setting avoids the complexity brought about by decentralized replacement in the prior art, reduces the need for disassembly and assembly at multiple positions, improves the maintenance efficiency of the overall device, makes the replacement of the activated carbon cartridge 22 simpler and faster, thereby reducing the operating burden of the operator, and regenerates the failed activated carbon cartridge 22 by local heating and desorption, thereby avoiding energy waste and local desorption problems caused by inconsistent adsorption effects, thereby effectively extending the service life of the activated carbon cartridge 22, reducing the replacement frequency, and saving operating costs.

[0048] like Figures 2 to 10 As shown: the rotating frame 2 is provided with channels 23 of the same number and one-to-one corresponding to the activated carbon cartridges 22, and two clamping assemblies 21 are respectively arranged on the two rotating frames 2 in a mirror-symmetrical state, the clamping assembly 21 includes a connecting shaft 211 that can slide along the axial direction of the channel 23, and a limiting plate 212 is arranged on the end of the connecting shaft 211 away from the channel 23, and an elastic member 213 is arranged between the limiting plate 212 and the channel 23, and the top and bottom of the filter box 1 are provided with driving assemblies 24 for synchronously driving the two clamping assemblies 21 to clamp or release the activated carbon cartridge 22.

[0049] By setting the same number of channels 23 as the activated carbon cartridge 22 and corresponding one to one, and cooperating with two mirror-symmetrical clamping components 21, the clamping and releasing operations of the activated carbon cartridge 22 are made more precise and synchronous, ensuring that the activated carbon cartridge 22 can operate stably when rotating or needs to be desorbed and replaced, avoiding misoperation or unstable clamping. The elastic member 213 provided on the connecting shaft 211 allows the clamping component 21 to automatically adjust the clamping force according to the slight changes of the activated carbon cartridge 22 during the clamping process, avoiding clamping too tight or too loose, extending the service life of the activated carbon cartridge 22, and improving the stability of equipment operation. The two clamping components 21 are driven to operate synchronously by the driving component 24 on the top, which not only improves the operating efficiency and reduces the frequency of manual intervention, but also realizes automatic clamping and releasing operations through the control system, greatly reducing the cost of manual maintenance. The design of the elastic member 213 between the limit plate 212 and the channel 23 ensures that the activated carbon cartridge 22 will not loosen or fall off due to rotation, vibration or other mechanical factors during the rotation process, ensuring the safety and stability of the equipment during operation.

[0050] like Figures 2 to 10 As shown: a first valve port 231 and a second valve port 232 are respectively provided at both ends of the channel 23, the connecting shaft 211 is a hollow structure, a valve core 2111 is provided on the connecting shaft 211 in the channel 23, and a plurality of vents 2112 are provided on one end of the connecting shaft 211 close to the valve core 2111.

[0051] When the clamping assembly 21 clamps the activated carbon cartridge 22, the valve core 2111 is located between the first valve port 231 and the second valve port 232. At this time, the gas can enter the channel 23 from the first valve port 231, and then enter the connecting shaft 2112 through the vent port 2111, so that the gas is passed into the activated carbon cartridge 22 through the connecting shaft 211. When the activated carbon cartridge 22 needs to be relaxed, the connecting shaft 211 moves along the channel 23 to drive the valve core 2111 to abut against the first valve port 231. At this time, the gas cannot enter the activated carbon cartridge 22, ensuring that the gas will not leak during the process of loosening the activated carbon cartridge 22. When the driving assembly 24 releases the control of the connecting shaft 211, the connecting shaft 211 will be moved under the action of the elastic member 213. The valve core 2111 is driven to move to the second valve port 232. At this time, the second valve port 232 can block the vent 2112, so that the gas can only enter the channel 23, but cannot enter the connecting shaft 211 through the vent 2112. As a result, after the connecting shaft 211 loses the power of the driving component 24, the gas will not leak when the clamping component 21 moves the rotating frame 2, ensuring that the gas can only pass through the activated carbon cartridge 22 as a transmission path. In the above manner, when the connecting shaft 211 moves along the channel 23, the abutment between the valve core 2111 and the first valve port 231 ensures that the gas will not be lost, thereby ensuring the sealing of the equipment, avoiding gas leakage due to power loss or system stagnation, and improving the safety and stability of the system.

[0052] like Figures 2 to 9 As shown: the two driving components 24 are arranged at the top and bottom of the filter box 1 in a mirror-symmetrical state, and the two driving components 24 each include two sliders 241 and two swing rods 242. The two sliders 241 can slide relatively along the axial direction of the filter box 1, and the two swing rods 242 are rotatably arranged on the two ends of the filter box 1 respectively. A driving rod 2422 for driving the limit plate 212 to move is arranged at the bottom of the swing rod 242, and a slide groove 2421 extending along the length direction thereof is arranged at the top of the swing rod 242. A sliding rod 2411 matching the slide groove 2421 is arranged on the slider 241, and the sliding rod 2411 can be slidably arranged on the slide groove 2421, and the movement of the slider 241 can drive the rotation of the swing rod 242.

[0053] The movement of the two relatively sliding sliders 241 drives the movement of the sliding rod 2411, and the sliding rod 2411 slides along the slide groove 2421, so that the swing rod 242 can swing relatively, thereby driving the movement of the limit plate 212 through the driving rod 2422 at the bottom of the swing rod 242, so that the limit plate 212 can loosen the clamping of the activated carbon cartridge 22. After the slider 241 is reset, the limit plate 212 can drive the connecting shaft 211 to move in the opposite direction under the reset of the elastic member 213 until the valve core 2111 abuts against the second valve port 232. The driving of the slider 241 can be realized by the screw rod 243, and the screw rod 243 can be rotatably arranged at the top or bottom of the filter box 1, and the screw rod 243 The threads at both ends are in opposite directions, and the two sliders 241 are sleeved on the screw rod 243 and cooperate with its threads. The rotation of the screw rod 243 can drive the relative movement of the two sliders 241, thereby realizing the control of the clamping assembly 21. Through the precise driving of the slider 241 along the screw rod 243, the relative sliding of the slider 241 can drive the rotation of the swing rod 242, and then control the movement of the limit plate 212, so as to realize the precise clamping and release of the activated carbon cartridge 22. This arrangement improves the accuracy and control of the operation, and makes the equipment more stable in the deodorization treatment. The arrangement of driving the connecting shaft 211 to reset by the elastic member 213 reduces the need for manual intervention and improves the continuity and working efficiency of the equipment.

[0054] like Figures 2 to 9 As shown: the limiting plate 212 is provided with a first guide plate 2121 capable of supporting the activated carbon cartridge 22 , and the first guide plate 2121 is located at one end of the limiting plate 212 away from the axis of the filter box 1 .

[0055] The first guide plate 2121 is located at the end of the limit plate 212 away from the axis of the filter box 1, so that when the clamping mechanism moves to the bottom of the filter box 1 with the rotating assembly, the activated carbon cartridge 22 can be supported by the guide plate. This arrangement effectively prevents the activated carbon cartridge 22 from tilting or deflecting during the clamping or loosening process, ensuring that the activated carbon cartridge 22 always maintains a stable posture, thereby improving the reliability of system operation. The arrangement of the first guide plate 2121 also plays a guiding role, which can better control the path of the activated carbon cartridge 22 during its movement and prevent the activated carbon cartridge 22 from deviating from the predetermined track, which is helpful for the activated carbon cartridge 22 to be moved. It can achieve more precise docking with the equipment, reduce errors, and improve the accuracy of the overall operation of the deodorization device, so that the activated carbon cartridge 22 can interact more smoothly with the clamping assembly 21, rotating frame 2 and other components, reducing the friction and collision between the activated carbon cartridge 22 and other components, thereby reducing the wear of the equipment and extending the service life of the activated carbon cartridge 22 and the equipment. The presence of the first guide plate 2121 helps to complete the assembly or disassembly operation more smoothly when replacing or desorbing the activated carbon cartridge 22, reducing the workload of manual adjustment and improving the operating efficiency of the entire device, especially when the activated carbon is frequently replaced.

[0056] The first guide plates 2121 of the two clamping assemblies 21 are slidably matched with each other, thereby matching the sliding of the clamping assemblies 21 to produce a distance change between the two.

[0057] like Figure 2 and Fig.10 As shown: the end of the connecting shaft 211 close to the activated carbon cartridge 22 is a conical structure.

[0058] The conical structure allows the clamping structure to drive the connecting shaft 211 to insert into the activated carbon cartridge 22 with less resistance, which helps the two to connect and prevents the position of the activated carbon cartridge 22 from shifting, resulting in a poor connection between the two.

[0059] like Figures 2 to 8 , Fig.11 and Fig.12 As shown: a first gear ring 25 fixedly connected to one of the rotating frames 2 is arranged on the side thereof, a rotating shaft 141 is arranged on the side of the first gear ring 25 in the filter box 1, a first gear 14 meshingly connected to the first gear ring 25 is arranged on the rotating shaft 141, and a first rotating drive motor 142 for driving the rotating shaft 141 to rotate is arranged on the side thereof.

[0060] By starting the first rotary drive motor 142, the output shaft of the first rotary drive motor 142 can drive the rotation of the rotary shaft 141 connected thereto, and the rotation of the rotary shaft 141 drives the rotation of the first gear 14, and the rotation of the first gear 14 drives the rotation of the first ring gear 25, and the rotation of the first ring gear 25 drives the rotation of the rotating frame 2, thereby enabling the rotating frame 2 to drive the activated carbon cartridge 22 to rotate, so that the granular filler inside the activated carbon cartridge 22 can move with the rotation, greatly increasing the contact area and contact frequency between the gas and the activated carbon, and compared with the activated carbon device with a traditional static structure, the equipment can improve the odor generated during the preparation of pig feed, and the deodorization efficiency is improved.

[0061] like Figures 2 to 8 As shown: the support frame 11 is horizontally arranged between the two rotating frames 2, the two sides of the support frame 11 are arranged in the interlayer 112, the desorption mechanism 15 is arranged in the interlayer 112, and the top and bottom of the support frame 11 are provided with a second guide plate 113 for guiding the activated carbon cartridge 22.

[0062] By setting the second guide plate 113 at the top and bottom of the support frame 11, the activated carbon cartridge 22 can be guided to the correct position more smoothly during the desorption or transmission process, reducing the possible tilting or deviation of the activated carbon cartridge 22, further improving the stability and operation accuracy of the device. During the movement of the activated carbon cartridge 22, the second guide plates 113 at the top and bottom provide guidance, support and buffering, so that the activated carbon cartridge 22 can accurately fall on the bottom of the support frame and the filter box 1, reducing the friction and collision between the activated carbon cartridge 22 and other components, thereby reducing the loss of the activated carbon cartridge 22 and extending its service life. The desorption mechanism 15 is arranged in the interlayer 112, making the desorption heating process more concentrated and efficient. With the setting of the second guide plate 113, it is ensured that each activated carbon cartridge 22 can accurately reach the heating area and fully complete the desorption process, thereby improving the regeneration effect of the activated carbon, optimizing the space utilization of the equipment, reducing the volume of the equipment, and also making the coordination between the various functional components inside the equipment smoother.

[0063] like Figures 2 to 6 and Fig.13 As shown: the cross-section of the receiving frame 111 is a U-shaped structure, a second gear ring 1111 is provided on one end of the receiving frame 111, a second gear 1112 for driving the second gear ring 1111 is provided on the outer wall of the filter box 1, and the second gear 1112 is driven by a second rotary drive motor 1113.

[0064] Through the U-shaped structure of the receiving frame 111, it can be rotatably set on the support frame 11, and at the same time can play the role of receiving the activated carbon cartridge 22. After it rotates 180 degrees, it can throw the activated carbon cartridge 22 from the support frame 11, so that it falls on the bottom of the filter box 1 and is received by the clamping mechanism. When the receiving frame 111 needs to be rotated, the second rotary drive motor 1113 is started, and the second gear 1112 connected to it is driven by the output shaft of the second rotary drive motor 1113. The rotation of the second gear 1112 drives the second gear ring 1111 to rotate, and the rotation of the second gear ring 1111 drives the rotation of the supporting frame, so that the activated carbon cartridge 22 can accurately fall on the bottom of the supporting frame and the filter box 1.

[0065] like Figures 2 to 8 As shown: Angle sensors for monitoring the rotation angles are provided on both the rotating frame 2 and the supporting frame.

[0066] Through the angle sensor (not shown in the figure), the rotation angle of the rotating frame 2 and the carrier frame can be monitored in real time to achieve precise control of the equipment movement. Through the signal feedback from the angle sensor, the system can ensure that the position of the activated carbon cartridge 22 and the carrier frame in each step is accurate and correct, avoiding inaccurate positioning or operation failure caused by rotation angle deviation. The application of the angle sensor enables the system to have the ability of automatic adjustment and monitoring. Through the feedback of sensor data, the system can intelligently adjust the position of the rotating frame 2 and the carrier frame to ensure that in each process, the equipment is in the most optimized working state, reduce manual intervention, and improve work efficiency.

[0067] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
