Description

Technical Field

[0001] This invention relates to the field of pig feed processing technology, and in particular to an integrated equipment for drying and sterilizing pig feed with high efficiency and energy saving. Background Technology

[0002] In the livestock industry, the drying and sterilization of pig feed is a key step in ensuring feed quality and reducing livestock diseases during feed production. Currently, the drying process of pig feed (especially pelleted feed and wet-mixed feed) mainly adopts two processes: belt conveyor drying and drum mixing drying. Among them, belt conveyor drying is widely used in large-scale feed production due to its advantages such as continuous operation and stable material transportation. Its core principle is to uniformly transport the feed to be processed to the drying and sterilization area through a conveyor belt, use hot air and other media to remove moisture from the feed, and can be combined with ultraviolet light, high temperature and other methods to achieve sterilization.

[0003] Current belt conveyor drying methods have some drawbacks in practical applications: pig feed usually contains a certain amount of moisture before drying, and some feeds (such as formula feeds with added oils and molasses) are inherently sticky. During the conveyor belt transport and drying process, they are very easy to stick to the conveyor belt due to oil residue, surface tension after moisture evaporation, or conveying pressure. These stuck feeds not only cannot be fed normally with the conveyor belt, but will also be circulated into the drying area with the conveyor belt, resulting in repeated drying. Over-drying will destroy the nutrients in the feed (such as vitamins and amino acids) and increase energy consumption. Residual feed that has not been completely removed may also mold on the conveyor belt, contaminating the fresh feed to be processed later, posing a food safety hazard.

[0004] To address the issue of feed adhesion, existing technologies primarily employ manual scraping or fixed scraper cleaning. Manual scraping requires periodic shutdowns, disrupting production continuity and increasing labor costs. While fixed scrapers allow for online operation, the rigid contact between the scraper and the conveyor belt easily causes belt wear, shortening equipment lifespan. Furthermore, some equipment attempts to reduce residue by vibrating the conveyor belt, but unidirectional vibration can lead to feed splashing, wasting materials and potentially affecting airflow stability in the drying and sterilization zone, thus reducing drying efficiency. Therefore, this paper proposes a highly efficient and energy-saving integrated drying and sterilization equipment for pig feed. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention provides an integrated equipment for drying and sterilizing pig feed with high efficiency and energy saving. The upper lifting component is designed with a gradual height difference so that the height at which the conveyor belt is lifted changes dynamically.

[0006] To achieve the above objectives, the present invention provides an integrated high-efficiency and energy-saving pig feed drying and sterilization equipment, including a belt conveyor with a drying and sterilization mechanism, and further comprising:

[0007] The upper push assembly is located in the middle gap of the conveyor belt of the belt conveyor and on one side of the unloading end. The upper push assembly includes push rods, pushing members, and deflecting members. At least three push rods are equally spaced along the width direction of the belt conveyor. The pushing members are assembled at the bottom end of the push rods. The pushing members drive the multiple push rods to push the conveyor belt upward in a conical shape. The height of the push rods is distributed in an undulating manner. The deflecting members are connected to the pushing members. During the process of the pushing members pushing the push rods upward, the deflecting members drive the push rods to deflect. The deflection directions of two adjacent push rods are opposite.

[0008] A drive assembly is connected to the frame of the pusher and the belt conveyor, and drives the pusher to move.

[0009] Preferably, the upper top assembly further includes a mounting base, which extends across the middle gap of the conveyor belt of the belt conveyor and is fixed to the frame, and the mounting base has a hollow structure along its length.

[0010] The top rod extends vertically through the upper surface of the mounting base.

[0011] Preferably, the pushing member includes:

[0012] The movable strip is movably disposed within the mounting base;

[0013] Multiple follower blocks, each having a first inclined surface, with one follower block fixed at the bottom end of each push rod, the thickness of adjacent follower blocks being different, and the thickness of alternating follower blocks being the same;

[0014] Multiple push blocks have a second inclined plane that is complementary to the first inclined plane. Each follower block corresponds to one push block. The heights of two adjacent push blocks are different. The push blocks that are distributed alternately have the same height. The push blocks with larger heights are corresponding to the follower blocks with larger thicknesses.

[0015] Preferably, adjacent deflecting elements are installed in opposite directions, and the deflecting elements include:

[0016] A protrusion is fixed to the side wall of the moving strip, with one protrusion corresponding to each follower block;

[0017] The first spring is inclinedly connected between the moving bar and the corresponding follower block.

[0018] Preferably, the upper surface of the mounting base has at least three equally spaced openings, and the top rod passes through the corresponding openings;

[0019] The top assembly also includes a guide, which includes a second spring connected to the inner end of the opening, and the free end of the second spring is connected to an arc-shaped plate.

[0020] Preferably, a guide block is fixed to the outer wall of the arc-shaped plate, and a guide groove is provided on the side wall of the opening, with the guide block and the guide groove forming a sliding fit.

[0021] Preferably, the bottom of the mounting base has a groove along its length, and a slide bar is fixed to the bottom of the moving bar, with the slide bar and the groove forming a sliding fit.

[0022] Preferably, the driving component includes:

[0023] The first telescopic rod is installed on the frame;

[0024] A vertical bar is vertically connected to the output end of the first telescopic rod;

[0025] The first connecting rod connects the vertical bar and the moving bar.

[0026] Preferably, a ball is rotatably mounted on the top end of the top rod.

[0027] Preferably, two upper top components are provided at intervals;

[0028] The driving component includes:

[0029] Second telescopic rod;

[0030] The second connecting rod is connected to the end of the moving bar. A guide wheel is installed on the outer end of the second connecting rod. The guide wheel is connected to the output end of the second telescopic rod through the connecting bar.

[0031] The third connecting rod is fixed to the frame and located between the two upper top components;

[0032] A hinge plate is hinged to the outer end of the third connecting rod, and the hinge plate is provided with symmetrical through holes, and the guide wheel forms a sliding fit with the through holes.

[0033] The technical solution provided by this invention may include the following beneficial effects:

[0034] 1. In this invention, the upper component is designed with a gradual height difference, so that the height at which the conveyor belt is lifted changes dynamically. The dried pig feed can slide and spread naturally due to gravity, avoiding local accumulation, thereby reducing energy consumption and food safety risks.

[0035] With the combination of gradually changing tilt angle and reverse tilt design, adjacent top rods tilt in opposite directions along the conveying direction, so that the feed is subjected to longitudinal tensile force and transverse shear force at the same time, making it easier for the adhering feed particles to detach from the conveyor belt and significantly reducing residue.

[0036] 2. In this invention, all forces (height difference, tilt angle, and jacking force) are adjusted gradually to avoid rigid impact. For example, the height difference gradually forms from the same to different, and the tilt angle of the jacking rod changes slowly with the spring tension. The conveyor belt and the jacking rod are subjected to uniform force, which can reduce the risk of stretching and deformation.

[0037] 3. In this invention, the dynamically deformed conveyor belt surface prevents feed from adhering stably and gradually detaches during gentle shaking, avoiding feed splashing or residue caused by unidirectional force.

[0038] 4. In this invention, the periodic extension and retraction of a single second telescopic rod can drive the two sets of upper jacking components to move alternately without the need for an additional power source, thus reducing equipment costs and energy consumption. Furthermore, the alternating operation of the two sets of upper jacking components avoids excessive wear caused by long-term stress on a single jacking rod, further extending the lifespan of the components.

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention. Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0057] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] Example

[0059] See Figures 1-7As shown, this invention proposes an integrated high-efficiency and energy-saving pig feed drying and sterilization equipment, including a belt conveyor 1 that transports pig feed to be dried and sterilized. The running speed of the conveyor belt can be adjusted by a variable frequency energy-saving motor, which can be flexibly adjusted according to parameters such as feed moisture and particle size to ensure that subsequent drying and sterilization processes can be fully carried out. A feeding hopper is provided at the feeding end of the belt conveyor 1. The length of the discharge port at the bottom of the hopper is less than the width of the conveyor belt. A spiral distributor can be installed inside the feeding hopper. When the pig feed to be processed is put into the feeding hopper, the spiral distributor can evenly spread the feed on the conveyor belt. The spreading thickness can be controlled between 2-10 cm, reducing the occurrence of uneven feed thickness on the conveyor belt and providing a stable material base for subsequent drying and sterilization processes. The belt conveyor 1 is equipped with a drying and sterilization mechanism, which includes a baffle 2. The baffle 2 is made of heat-insulating material, which can effectively reduce the internal heat loss. To reduce energy consumption, a hot air blower 3 and a sterilizer 4 are sequentially installed on the baffle 2 along the conveying direction of the belt conveyor 1. The outlet of the hot air blower 3 is equipped with evenly distributed nozzles, which are set at a certain downward angle (such as 45°) to allow the hot air to blow more directly onto the feed on the conveyor belt. The power of the hot air blower 3 can be selected according to the processing volume, and can be 5-15 kilowatts. The temperature of the hot air it produces can be adjusted between 50-80℃. The hot air blower 3 can also be equipped with a temperature sensor and an automatic temperature control device. When the temperature inside the baffle 2 exceeds the set value, the hot air blower 3 will automatically reduce its power. The sterilizer 4 can sterilize the dried pig feed. The sterilizer 4 can use ultraviolet sterilization. When using ultraviolet sterilization, several ultraviolet lamps can be installed inside the top of the baffle 2. The power and number of lamps are determined according to the width of the baffle 2 and the running speed of the conveyor belt to ensure that the ultraviolet rays can more comprehensively cover the feed on the conveyor belt. In addition, the entire equipment is equipped with a controller. Operators can set parameters such as drying temperature, sterilization time, and conveyor belt speed through the touch screen. The equipment will automatically run according to the set parameters. The controller can also monitor the operating status of the equipment in real time. If the hot air blower 3 fails or the sterilizer 4 is abnormal, an alarm signal will be issued in time and the machine will be automatically stopped to avoid equipment damage and the production of unqualified feed.

[0060] In addition, the integrated pig feed drying and sterilization equipment also includes an upper support assembly 5 and a drive assembly 6. The upper support assembly 5 is located in the middle gap of the conveyor belt of the belt conveyor 1 and is located on one side of the feeding end. The upper support assembly 5 includes push rods 52, pushing members 53, and deflecting members 54. At least three push rods 52 are arranged at equal intervals along the width direction of the belt conveyor 1. In the initial stage, the upper end faces of all push rods 52 are flush. The pushing members 53 are assembled at the bottom end of the push rods 52, and the multiple push rods 52 are driven by the pushing members 53. The conveyor belt is pushed upward in a cone shape, and after the push rod 52 is pushed, the height of all the push rods 52 is distributed in an undulating state to remove the pig feed attached to the conveyor belt. The deflector 54 is connected to the pusher 53. During the process of the pusher 53 pushing the push rod 52 upward, the push rod 52 is deflected by the deflector 54, and the deflection directions of two adjacent push rods 52 are opposite. The drive assembly 6 is connected to the frame of the pusher 53 and the belt conveyor 1, and drives the pusher 53 to move through the drive assembly 6.

[0061] Among them, a rolling ball 521 is rolled at the top of the push rod 52. When the push rod 52 pushes the conveyor belt upward, the rolling ball 521 contacts the conveyor belt, converting the original sliding friction into rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, which greatly reduces the frictional loss between the conveyor belt and the top of the push rod 52. Even if the push rod 52 deflects (with or against the conveying direction), the rolling ball 521 can still adapt to the conveyor belt by its own rolling, avoiding additional frictional damage caused by the deflection of the push rod 52.

[0062] participate Figures 4-5 As shown, the upper top component 5 also includes a mounting base 51, which is long and narrow. The mounting base 51 passes through the gap in the middle of the conveyor belt of the belt conveyor 1 and is fixed on the frame of the belt conveyor 1. The mounting base 51 has a hollow structure along its length.

[0063] The push rod 52 extends vertically through the upper end face of the mounting base 51, and the lower end of the push rod 52 is located in the hollow cavity of the mounting base 51.

[0064] participate Figures 5-7As shown, the pusher 53 includes a moving strip 531, multiple follower blocks 532, and multiple push blocks 533. The moving strip 531 is slidably mounted to the interior of the mounting base 51. Specifically, a groove 512 is formed along the length direction at the bottom of the interior of the mounting base 51. A slide bar 56 is fixed to the bottom end of the moving strip 531, and the slide bar 56 forms a sliding fit with the groove 512. A ball bearing can be set at the bottom end of the groove 512. The ball bearing can convert the sliding friction between the moving strip 531 and the mounting base 51 into rolling friction, improving the response speed and smoothness of the moving strip 531, and ensuring a stable working state even in high-frequency reciprocating motion. Each follower block 532 has a first inclined surface, and a follower block 532 is fixed to the bottom end of each push rod 52. The thickness of two adjacent follower blocks 532 is different, and the thickness of the alternately distributed follower blocks 532 is the same. Each push block 533 has a first inclined surface. The complementary second inclined surface, each follower block 532 corresponds to a push block 533, the height of two adjacent push blocks 533 is different, the push blocks 533 distributed alternately are of the same height, the push block 533 with a larger height is set to correspond to the follower block 532 with a larger thickness to form a matched transmission unit, and the push block 533 with a smaller height is set to correspond to the follower block 532 with a smaller thickness to form another transmission unit, and the inclination of the second inclined surface on the push block 533 with a larger height is greater than the inclination of the second inclined surface on the push block 533 with a smaller height. When the moving bar 531 drives the push block 533 to move, the second inclined surface of the push block 533 contacts the first inclined surface of the follower block 532 and generates relative sliding. Since the inclination and size of the inclined surfaces of different sets of transmission units are different, the horizontal displacement of the moving bar 531 can be converted into the vertical lifting and lowering of the follower block 532 with different amplitudes, thereby driving the top rod 52 to achieve differentiated pushing operation.

[0065] participate Figure 4 As shown, the drive assembly 6 includes a first telescopic rod 61, a vertical bar 62, and a first connecting rod 63. The first telescopic rod 61 is mounted on the frame. The first telescopic rod 61 is preferably an electric telescopic rod and is electrically connected to the controller. The vertical bar 62 is vertically connected to the output end of the first telescopic rod 61. The first connecting rod 63 is connected between the vertical bar 62 and the moving bar 531. The first telescopic rod 61 can drive the vertical bar 62 to extend and retract, so that the first connecting rod 63 can pull and push the moving bar 531. When the moving bar 531 is pushed inward, the moving bar 531 drives the push block 533 to move and push the follower block 532 with a first inclined surface, so that the top rod 52 moves upward to push the conveyor belt.

[0066] participate Figures 5-7 As shown, adjacent deflector elements 54 are installed in opposite directions, and each deflector element 54 includes:

[0067] A protrusion 542 is fixed to the side wall of the moving strip 531, and each follower block 532 corresponds to a protrusion 542;

[0068] The first spring 541 is obliquely connected between the moving bar 531 and the corresponding follower block 532. When the moving bar 531 is pushed inward, the push block 533 pushes the corresponding follower block 532 upward. At this time, the first spring 541 on one side is stretched. The first spring 541 connected to the follower block 532 is gradually stretched due to the upward movement of the follower block 532. During the stretching process of the first spring 541, a pulling force is generated towards its mounting side. This pulling force is not vertical but has a lateral component. As the follower block 532 continues to move upward, the stretching amount of the first spring 541 gradually increases, and its lateral component force also increases accordingly, causing the push rod to... During the upward process, the push rod 52 is gradually subjected to a pulling force towards the side where the first spring 541 is installed. Under the action of the pulling force, the push rod 52 no longer maintains a vertical upward state, but will gradually tilt towards the side of the first spring 541 along with the follower block 532. As the tilt angle of the push rod 52 gradually increases, the position of its top end will also gradually shift away from the original vertical state towards the end where the first spring 541 is installed. When the top end of the push rod 52 contacts the conveyor belt, the tilt state will change the way the top end of the push rod 52 squeezes the conveyor belt. It is no longer a direct squeeze in the vertical direction, but presents a gradually tilting squeeze effect from one side to the other.

[0069] Secondly, see Figures 4-5 as well as Figure 11 As shown, the upper surface of the mounting base 51 has at least three openings 511 at equal intervals, and the top rod 52 passes through the corresponding openings 511.

[0070] The top assembly 5 also includes a guide member 55, which includes a second spring 552 connected to the inner end of the through-hole 511. The free end of the second spring 552 is connected to an arc-shaped plate 551. The side of the arc-shaped plate 551 facing the top rod 52 is smooth and can be equipped with balls to reduce friction. A guide block 553 is fixed on the outer wall of the arc-shaped plate 551. A guide groove 554 is provided on the side wall of the through-hole 511. The guide block 553 and the guide groove 554 form a sliding fit. By moving the guide block 553 in the guide groove 554, the movement of the arc-shaped plate 551 along the length direction of the three through-holes 511 can be restricted, and the arc-shaped plate 551 and the second spring 552 can be prevented from twisting.

[0071] The second spring 552 works in conjunction with the first spring 541 to facilitate the rapid reset of the push rod 52 after descent.

[0072] As described above, in specific use, the controller controls the movement of the first telescopic rod 61. When the first telescopic rod 61 retracts, the vertical bar 62 drives the first connecting rod 63 to retract inward, so as to squeeze the moving bar 531. The moving bar 531 moves and drives the push block 533 with the second inclined surface on it to push the follower block 532 with the first inclined surface, which in turn pushes the top rod 52 with the rolling ball 521 to move upward, so as to use the top rod 52 to push the conveyor belt. When the conveyor belt is lifted, local deformation occurs, and the adhered pig feed will detach from the surface due to the tensile force.

[0073] In this process, because the adjacent push blocks 533 push the follower blocks 532 to different heights, the adjacent push rods 52 have different upward lifting heights relative to the unloading end of the conveyor belt. The conveyor belt is lifted to different heights in some areas (e.g., 4cm in some places and 2cm in others), which will create a height difference in the pig feed on the conveyor belt. The pig feed at the higher convex points will slide and spread to the lower areas due to gravity, which is conducive to the spread of pig feed. Moreover, during the upward process of the adjacent push rods 52, the height difference is gradually formed during the upward process. Compared with the upward lifting at a fixed height interval, when the height difference is gradually formed from the same height, the conveyor belt will be lifted into irregular, dynamically changing folds or inclined surfaces. As the height difference of the push rods 52 gradually increases, the surface of the conveyor belt will produce slight shaking and changes in the tilt angle. The adhering pig feed can be better separated from the conveyor belt, and sudden upward lifting can avoid the pig feed splashing. In addition, when the height difference is gradually formed, the force at the contact point changes locally, reducing the stretching of the conveyor belt or the deformation of the push rods 52 caused by sudden force.

[0074] Secondly, during the upward pushing process of the push rod 52, the first spring 541 is stretched, causing the pulling follower block 532 to tilt towards one side of the first spring 541. This causes the upper end of the push rod 52 to gradually tilt towards the other side during the upward pushing of the conveyor belt. This transforms the upward pushing force, which originally only acted on a fixed point of the conveyor belt, into a pushing force covering a certain lateral range, effectively expanding the upward pushing range of the conveyor belt. Furthermore, the tilting directions of the tops of two adjacent push rods 52 are different. For example, one push rod 52 tilts along the conveying direction, while the adjacent push rod 52 tilts against the conveying direction. This reverse tilting creates a lateral twisting shape in the area where the conveyor belt is pushed up. The pig feed on the surface of the conveyor belt is subjected not only to longitudinal tensile force but also to lateral shear force. Under the combined action of these two forces, the feed particles adhering to the surface are more easily detached from the surface of the conveyor belt, further facilitating more thorough feeding and reducing pig feed residue.

[0075] In summary, this composite motion of "gradual height difference + gradual tilt angle + reverse tilt" keeps the conveyor belt surface in a state of dynamic adjustment. Its deformation shape, tilt direction, and the distribution of the top protrusions are constantly changing. Pig feed cannot be stably attached to a certain position in the feeding section of the conveyor belt, nor will it be concentrated and splashed due to a force in one direction. Instead, it gradually detaches from the conveyor belt through slow stretching, shaking, and tilting. At the same time, all force changes (height difference, tilt angle, and thrust) are gradually adjusted. The force on the conveyor belt and the top rod 52 is always in a state of gradual loading, which fundamentally avoids equipment damage caused by rigid impact and makes the feed detachment process gentler and more efficient.

[0076] Additionally, it should be noted that the retracted length of the first telescopic rod 61 after extension does not exceed the length of the follower block 532, so as to ensure that after the push block 533 pushes the follower block 532 to rise to the maximum height, the push block 533 does not disengage from the follower block 532. This design can effectively prevent transmission interruption caused by the two disengaging.

[0077] The controller can also control the periodic extension and retraction speed of the first telescopic rod 61. The periodic extension and retraction speed of the first telescopic rod 61 is adapted to the conveying speed of the conveyor belt. When the conveyor belt increases its conveying speed, the controller will synchronously adjust the periodic extension and retraction frequency of the first telescopic rod 61, so that its extension and retraction speed increases accordingly. Conversely, if the conveyor belt decreases its conveying speed, the periodic extension and retraction rhythm of the first telescopic rod 61 will also slow down accordingly.

[0078] Example 2: See Figure 3 as well as Figures 9-10 As shown, two upper top components 5 are spaced apart and arranged in parallel. The drive component 6 includes a second telescopic rod 64, a second connecting rod 65, a third connecting rod 67, and a hinge plate 66. The second telescopic rod 64 can be an electric telescopic rod. The second connecting rod 65 is connected to the end of the moving bar 531. A guide wheel 68 is installed on the outer end of the second connecting rod 65. The guide wheel 68 is connected to the output end of the second telescopic rod 64 through a connecting bar. The third connecting rod 67 is fixed on the frame and is located between the two upper top components 5. The hinge plate 66 is hinged to the outer end of the third connecting rod 67. Symmetrical through holes 661 are provided on the hinge plate 66. The guide wheel 68 and the through holes 661 form a sliding fit to realize the dynamic adjustment of the hinge plate 66 around the guide wheel 68.

[0079] As described above, in the initial operating state of the equipment, the top rods 52 of the two sets of upper lifting components 5 are kept at the same horizontal height. At this time, the second telescopic rod 64 is in the middle retracted position. In use, the second telescopic rod 64 drives the second connecting rod 65 on one side to retract inward through the connecting strip. At this time, the second connecting rod 65 pushes the moving strip 531 inward to realize the action of the top rod 52 of the upper lifting component 5 (similar to Embodiment 1, which will not be described again here). When the second telescopic rod 64 extends outward, the original top rod 52 falls back to the initial position. As the second telescopic rod 64 continues to extend outward, the hinge plate 66 can be used to squeeze the other second connecting rod 65 to make the corresponding moving strip 531 move inward, and then make the top rod 52 of the corresponding upper lifting component 5 act. In this way, the second telescopic rod 64 extends and retracts periodically, and the two sets of upper lifting components 5 can be used periodically to lift the conveyor belt unloading section. The contact and force between the top rod 52 and the conveyor belt are alternated to avoid the top rod 52 being subjected to force for a long time and causing premature damage.

[0080] Secondly, the movement of the two sets of upper lifting components 5 is achieved by only one power source, namely the periodic extension and retraction of the second telescopic rod 64, eliminating the need to equip the two sets of upper lifting components 5 with separate drive devices, thus reducing equipment costs.
