Detailed implementation manners

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Embodiment 1:

[0056] Refer to Figure 1 -Figure -8.

[0057] A chicken manure drying device includes: a drying unit 1, and the drying unit 1 has multiple layers of drying chambers 11;

[0058] Wherein, the bottom surface of the drying chamber 11 is a receiving layer 12, the receiving layer 12 has ventilation holes, and the ventilation holes communicate with adjacent drying chambers 11;

[0059] Wherein, one side in the width direction of the drying unit 1 is a blowing side 13, and the opposite side of the blowing side 13 is a material conveying side 14;

[0060] Wherein, one of the adjacent two layers of drying chambers 11 is provided with a fan 131, the fan 131 is arranged on the blowing side 13 and blows towards the material conveying side 14;

[0061] Wherein, the material conveying side 14 of the drying chamber 11 provided with the fan 131 is provided with a closing door 141, and the material conveying sides 14 of the remaining drying chambers 11 are in an open state;

[0062] The feeding unit 2 is arranged inside the conveying and drying chamber 11;

[0063] Among them, the feeding unit 2 includes: a feeding device 21 that conveys materials into the drying chamber 11;

[0064] a discharging device 22 that conveys the dried materials out of the drying chamber 11;

[0065] A transfer unit 3 drives the feeding unit 2 to move along the length direction and height direction of the drying chamber 11.

[0066] Chicken manure contains rich nutrients and trace elements and can be made into organic fertilizer or feed. Before processing chicken manure, it needs to be dried first to avoid fermentation and deterioration. The drying equipment in the prior art is in the form of a drum. After filling the chicken manure into the drum, the drum rotates continuously and dries the chicken manure inside. The rotation of the drum is to make the chicken manure evenly heated, similar to a cement mixer, lifting the chicken manure and then dropping it. However, chicken manure is prone to caking at a certain humidity, especially for a drum with a smaller diameter, the vertical drop is smaller, and there is a large amount of chicken manure at the bottom of the drum as a buffer, which makes it difficult for the caked chicken manure to break when it falls, resulting in the chicken manure blocks getting bigger and bigger. For large chicken manure blocks, hot air is difficult to reach the inside of the chicken manure blocks, resulting in the central area of the chicken manure blocks not being dried. The large chicken manure blocks need to be broken again and dried again, resulting in low drying efficiency.

[0067] Moreover, it is difficult to make a drum with a large diameter for the drying equipment. The reasons are as follows: 1. When the drum diameter is large, it will first cause the center of gravity of the equipment to be unstable and increase the requirement for the matching accuracy of each component; 2. Increasing the drum diameter does not improve the drying efficiency as much as increasing the drum length. The thickness of the chicken manure loaded at the bottom of the drum cannot be too thick, otherwise hot air is difficult to dry the deep-layer chicken manure, and when the thicker chicken manure rotates in the drum, it is difficult to be evenly scattered.

[0068] Another problem is that the energy required for the continuous rotation of the drum is very large. The device itself is for the secondary utilization of resources (chicken manure), but it consumes a large amount of energy during the operation of the equipment.

[0069] Therefore, this application provides a static drying equipment. First, a general drying unit 1 is set up. The drying unit 1 is provided with multiple drying chambers 11. The chicken manure is spread in the drying chambers 11. Among them, the bottom surface of the drying chamber 11 is a receiving layer 12, and the receiving layer 12 is provided with ventilation holes to ensure the gas flow between the upper and lower drying chambers 11.

[0070] One side in the width direction of the drying unit 1 is the air-blowing side 13, and the opposite side of the air-blowing side 13 is the feeding side 14. The air-blowing side 13 is provided with a fan 131 to output hot air to the chicken manure in the drying chamber 11 to achieve the purpose of drying the moisture of the chicken manure.

[0071] Furthermore, not every layer of drying chamber 11 is provided with a fan 131, but the arrangement of each layer of drying chamber 11 is such that the feeding area of ​​a layer of drying chamber 11 provided with a fan 131 is provided with a closed door 141, and the feeding area of ​​a layer of drying chamber 11 not provided with a fan 131 is in an open state. Specifically, when the closed door 141 is closed, the drying chamber 11 provided with the fan 131 is in a closed state. When the fan 131 is started, the airflow is directed toward the feeding area. Due to the blocking of the closed door 141, the airflow cannot flow out of the feeding area, and the internal air pressure of the drying chamber 11 of this layer increases. The feeding area of ​​the adjacent drying chamber 11 is in an open state, and the internal air pressure is the same as the atmospheric pressure. The airflow will flow to the adjacent drying chamber 11 through the vents of the upper and lower receiving layers 12. Since the chicken manure is spread on the receiving layer 12, the gas can evenly dry the chicken manure when it flows through the vents. Furthermore, the drying chamber 11 provided with the fan 131 is in a relatively closed state, and can continuously accumulate heat. Under the premise of not increasing the power of the fan 131, a higher temperature is obtained, and drying can be achieved faster and better.

[0072] When the drying unit 1 is drying, the conveying unit can be moved to a layer of the drying chamber 11 where the closing door 141 is not provided, so as to avoid interfering with the closing of the closing door 141 .

[0073] In the prior art, it is only necessary to pour the chicken manure into the drum, and the drum can mix the chicken manure evenly when rotating. In the present application, the chicken manure needs to be evenly spread on the receiving layer 12 of each layer, so the drying equipment of the present application is also equipped with a feeding unit 2 and a transfer unit 3. The feeding unit 2 is responsible for continuously outputting the chicken manure, and the transfer unit 3 is responsible for driving the feeding unit 2 to move the position so that the chicken manure is evenly spread on all parts of the receiving layer 12.

[0074] At the same time, the chicken manure that has been dried needs to leave the drying chamber 11 , so the feeding unit 2 is divided into two parts: a feeding device 21 and a discharging device 22 .

[0075] The feeding device 21 is specifically configured as a first screw conveyor 211. A screw conveyor is a machine that uses an electric motor to drive a screw to rotate and push materials to achieve the purpose of conveying. The first screw conveyor 211 is arranged along the width direction of the drying chamber 11, that is, the conveying direction is parallel to the width direction of the drying chamber 11. One end of the first screw conveyor 211 is provided with a first feeding port 2112, which is the same as the screw conveyor in the prior art. However, for the discharge port of the first screw conveyor 211 (it can be understood that if the discharge port is not arranged at the end of the screw conveyor, the discharge port must be downward to rely on gravity for discharging), that is, the first discharge port 2113 is arranged along the conveying direction of the screw conveyor. The length of the first discharge port 2113 is slightly less than the width of the receiving layer 12, so that the first screw conveyor 211 only needs to move along the length direction of the receiving layer 12 to evenly spread the chicken manure.

[0076] The discharging device 22 is specifically configured as a second screw conveyor 221, which is also arranged along the width of the drying chamber 11 and is parallel to the first screw conveyor 211. The end of the second screw conveyor 221 is provided with a second discharge port 2212. The second discharge port 2212 is arranged outside the drying chamber 11 and has a second feeding port 2211 along the conveying direction of the second screw conveyor 221; the length of the second discharge port 2212 is preferably greater than the width of the receiving layer 12 to prevent the chicken manure from spilling during feeding. The second feeding port 2211 faces the top of the chain plate type turning machine 222.

[0077] The discharging device 22 further includes a chain plate type turning machine 222, also known as a chain plate type piling machine. Its structure is similar to that of a chain plate conveyor belt, and the conveying surface has a plurality of turning plates. The conveying direction forms an angle with the plane to be turned (the plane for placing materials, which is the bearing surface in this application). The chain plate type turning machine 222 in the prior art is often fixed and has a large volume, requiring a large vertical drop to ensure that the materials come into full contact with the air when they fall. However, the chain plate type turning machine 222 in this application is not for piling up the materials. In this application, the second screw conveyor 221 is arranged behind the chain plate type turning machine 222, so that the materials just fall into the second feeding port 2211 when they fall, and then the second screw conveyor 221 conveys the materials to the discharge port. The rear of the chain plate type turning machine 222 refers to the side where the materials fall after being turned by the chain plate type turning machine 222.

[0078] It should be noted that the first screw conveyor 211 and the second screw conveyor 221 are both arranged along the width direction of the drying chamber 11, rather than the length direction. This is because of the overall size of the drying chamber 11. The drying chamber 11 needs to have a relatively large area to receive materials, so the length and width dimensions are relatively large. If the first screw conveyor 211, the second screw conveyor 221, and the chain plate type turning and throwing machine 222 are set according to the length, it will result in an overly large conveying unit and increase the difficulty for the transfer unit 3 to drive the conveying unit. As for why the drying chamber 11 must be set to a large size, it is because: the advantage of this application compared to the existing drum type drying equipment lies in the drying effect and drying efficiency. However, this application requires the conveying unit to spread the materials evenly, and spreading materials is a rather troublesome process. Therefore, this application uses a larger drying chamber 11 to dry more chicken manure each time, thereby reducing the number of times of the material spreading process. At the same time, the drying chamber 11 with a larger bottom area has a more stable center of gravity. By setting more layers of drying chambers 11, the total amount of materials dried in a single time is obtained. While increasing the single - time drying amount, it does not affect the floor area of the equipment in the factory, making full use of the high - altitude space. Therefore, this application is more suitable for drying a large amount of chicken manure simultaneously.

[0079] Embodiment 2

[0080] Refer to Figure 4 -Figure - 8.

[0081] The transfer unit 3 includes: an X - guiding driving part 31, which forms an X - guiding stroke along the length direction of the drying chamber 11 and drives the conveying unit to move along the length direction of the drying chamber 11. The widths of the first discharge port 2113, the second feed port 2211, and the chain plate type turning and throwing machine 222 (in the chain plate type turning and throwing machine 222, the direction perpendicular to the conveying direction in the conveying surface is the width, and the conveying direction is the length of the chain plate type turning and throwing machine 222, rather than determining the length and width of the chain plate type turning and throwing machine 222 based on the size of the distance) are all arranged along the width of the drying chamber 11. Therefore, each time the first discharge port 2113 discharges materials, it can spread a layer of materials with a length similar to the width of the drying chamber 11, and the material taking coverage area of the chain plate type turning and throwing machine 222 each time is also an area with a length similar to the width of the drying chamber 11. The X - guiding driving part 31 drives the conveying unit to act along the X - guiding stroke, so that the spreading area and the material taking area can cover the receiving layer 12.

[0082] A Z - guiding driving part 32 forms a Z - guiding stroke along the height direction of the drying unit 1. When the conveying unit completes the material spreading or material taking on one layer of the drying chamber 11, it is necessary to perform material spreading or material taking on the next layer of the drying chamber 11.

[0083] Specifically, the Z - guiding driving part 32 is provided with a loading rack 33, the conveying unit is arranged on the loading rack 33, and the Z - guiding driving part 32 drives the loading rack 33 to move along the Z - guiding stroke.

[0084] More specifically, both the X - guiding drive unit 31 and the Z - guiding drive unit 32 are actually linear drive mechanisms with a relatively long movement distance. It is most suitable to adopt ball screw drive or rack - and - pinion drive. These are two of the most basic mechanical drive methods, and their principles and structures will not be introduced in detail in this application.

[0085] Furthermore, the X - guiding drive unit 31 has an upper guide rail 311 and a lower guide rail 312, which are respectively arranged at the upper and lower ends of the drying unit 1.

[0086] The Z - guiding drive unit 32 is provided with an upper connecting plate 321, a lower connecting plate 322 and a guiding column 323.

[0087] Among them, the upper connecting plate 321 is slidably connected to the upper guide rail 311, and the lower connecting plate 322 is slidably connected to the lower guide rail 312.

[0088] The upper connecting plate 321 is provided with a driving turntable mechanism 324, the lower connecting plate 322 is provided with a driven turntable mechanism 325, and both ends of the guiding column 323 are respectively connected to the driving turntable mechanism 324 and the driven turntable mechanism 325.

[0089] The driving turntable mechanism 324 drives the guiding column 323 to rotate, so that the feeding unit 2 is in a working state or an avoidance state.

[0090] The working state is that the conveying direction of the first screw conveyor 211 is parallel to the width direction of the drying chamber 11.

[0091] In the avoidance state, the included angle b between the conveying direction of the first screw conveyor 211 and the width direction of the drying chamber 11 is greater than 90 degrees.

[0092] It is very easy to achieve linear motion. However, it should be noted that the conveying unit must be located inside the drying chamber 11 when feeding and taking materials. Therefore, if the conveying unit directly moves along the Z-guide stroke, it will inevitably cause interference between the unit and the receiving layer 12 of the drying chamber 11. Therefore, when moving to the adjacent drying chamber 11, it needs to be in an avoidance state to bypass the receiving layer 12. In this embodiment, the Z-guide driving part 32 is provided with an upper connecting plate 321, a lower connecting plate 322 and a guide column 323. The upper connecting plate 321 is slidably connected to the upper guide rail 311 of the X-guide driving part 31, and the lower connecting plate 322 is slidably connected to the lower guide rail 312 of the X-guide driving part 31. The guide column 323 is arranged between the upper connecting plate 321 and the lower connecting plate 322 and serves as the guide rail for the Z-guide stroke. Among them, the upper connecting plate 321 is provided with a driving turntable mechanism 324, the lower connecting plate 322 is provided with a driven turntable mechanism 325, and both ends of the guide column 323 are fixedly connected to the driving turntable mechanism 324 and the driven turntable mechanism 325 respectively. The driving turntable mechanism 324 drives the guide column 323 to rotate. When the driving turntable mechanism 324 rotates 90 degrees, the conveying direction of the first screw conveyor 211 (the conveying direction of the second screw conveyor 221 and the width direction of the chain plate type turning and throwing machine 222 are parallel to the first screw conveying direction) is parallel to the length of the drying chamber 11, so that the conveying unit leaves the drying chamber 11.

[0093] The structure of the driven turntable mechanism 325 is at least divided into two layers. The lower-layer driven turntable is fixedly connected to the lower connecting plate 322, and the upper-layer driven turntable is fixedly connected to the guide column 323. The upper and lower layers of driven turntables are rotatably connected. For the driving turntable mechanism 324, additional driving components need to be set. For example: the upper-layer driving turntable of the driving turntable mechanism 324 is fixedly connected to the guide column 323, the lower-layer driving turntable is fixedly connected to the upper connecting plate 321, a turbine is arranged on the lower driving turntable, the driving component is set as a motor, the main shaft of the motor is connected to a worm, and the driving component can be fixedly arranged on the upper connecting plate 321 or the upper-layer driving turntable. The worm drives the turbine to rotate the lower driving turntable, and then makes the guide column 323, the loading rack 33 and the conveying unit rotate. The driving component can also be connected to a gear, and the outer contour of the lower driving turntable is set as a gear to realize rotation through gear cooperation.

[0094] Embodiment 3

[0095] Refer to Figure 5 。

[0096] It further includes a centralized feeding unit 4. The centralized feeding unit 4 is set as a conveyor belt arranged along the length direction of the drying chamber 11, and the centralized feeding unit 4 is arranged on the top of the drying unit 1;

[0097] A centralized feeding port 41 is provided at the top of the guiding vertical column 323, and the centralized feeding port 41 is lower than the upper surface of the centralized feeding unit 4; the centralized feeding port 41 is communicated with the first feeding port 2112 through a pipeline;

[0098] A scraper 42 is provided on the upper connecting plate 321. The orthogonal projection of the scraper 42 on the top surface of the drying unit 1 forms an angle a with the conveying direction of the centralized feeding unit 4, and the opening of the angle a faces the starting end of the centralized feeding unit 4.

[0099] In this embodiment, a centralized feeding unit 4 is further provided to continuously convey the materials to be dried to the first feeding port 2112.

[0100] The centralized feeding unit 4 is arranged in the form of a conveyor belt and is located at the top of the drying unit 1 (the materials on the ground are transported to the upper centralized feeding unit 4 by means of an inclined conveyor belt or hoisting). The conveying direction is parallel to the length direction of the drying chamber 11.

[0101] A centralized feeding port 41 is provided at the upper end of the guiding vertical column 323. The centralized feeding port 41 is communicated with the first feeding port 2112 through a pipeline. Specifically, the pipeline can be arranged as a corrugated pipe or a telescopic sleeve structure. When the conveying unit moves along the Z guiding stroke, the pipeline can adaptively extend or shorten, and the pipeline can rotate with the guiding vertical column 323 to avoid the pipeline being distorted after the first feeding port 2112 rotates.

[0102] A scraper 42 is provided on the upper connecting plate 321. The materials on the centralized feeding unit 4 are scraped off to the centralized feeding port 41 through the scraper 42. Specifically, the centralized feeding port 41 is lower than the upper surface of the centralized feeding unit 4. The orthogonal projection of the scraper 42 on the top surface of the drying unit 1 forms an angle a with the conveying direction of the centralized feeding unit 4, and the opening of the angle a faces the starting end of the centralized feeding unit 4. That is, the scraper 42 is inclined relative to the conveying direction of the centralized feeding unit 4. The conveying direction of the centralized feeding unit 4 is the same as the direction of the X guiding stroke. When the materials on the centralized feeding unit 4 come into contact with the scraper 42, a force parallel to the above direction will be generated. And we need to generate a force perpendicular to the conveying direction of the centralized feeding unit 4 and towards the centralized feeding port 41 to make the materials fall into the centralized feeding port 41. Part of the force in the conveying direction is decomposed into a force towards the centralized feeding port 41 through the inclined surface of the scraper 42. During the conveying process of the centralized feeding unit 4, the scraper 42 continuously scrapes the materials to the centralized feeding port 41.

[0103] Embodiment 4

[0104] Refer to Figure 7 。

[0105] A centralized discharge port 5 is provided at the lower end of the guiding upright column 323, and the centralized discharge port 5 is communicated with the second discharge port 2212 through a pipeline.

[0106] When discharging materials from the high-level drying chamber 11, the distance between the second feeding port 2211 and the ground is relatively large. Direct discharging will generate a large amount of dust, and the materials will scatter over a large area and are difficult to gather, which affects the factory environment. Moreover, the dust is easily inhaled by workers, affecting their health. The distance between the lower end of the guiding upright column 323 and the ground is relatively close, and the vertical position will not change. Therefore, in this application, a centralized discharge port 5 is provided at the lower connecting plate 322, and the centralized discharge port 5 is communicated with the second discharge port 2212 through a pipeline. The pipeline can be specifically set as a corrugated pipe or a telescopic sleeve structure. When the second discharge port 2212 is raised or lowered, the pipeline will adaptively extend or contract. When the second screw conveyor 221 is conveying materials in the high-level drying chamber 11, the dust generated by the falling materials will be largely wrapped by the pipeline, avoiding the generation of dust by the materials and the scattering of the materials.

[0108] Refer to Figure 6 。

[0109] The loading rack 33 is provided with a switching guiding part 61 to form a switching stroke; the switching stroke is parallel to the length direction of the drying chamber 11;

[0110] The second screw conveyor 221 and / or the chain plate type turning and throwing machine 222 slide along the switching stroke;

[0111] A switching driving part 62 is used to increase or decrease the distance between the second screw conveyor 221 and the chain plate type turning and throwing machine 222.

[0112] A switching guide 61 is provided in the loading frame 33. The switching guide 61 is specifically provided as a guide rail and a switching drive 62. The guide rail is arranged along the length direction of the drying chamber 11 to form a switching stroke parallel to the length direction of the drying chamber 11. The switching drive 62 can be provided as a driving component such as an electric push rod and a lead screw to drive the second screw conveyor 221 and / or the chain plate type flipping machine 222 to move along the switching stroke. For example, the end of the electric push rod is fixedly connected to the second screw conveyor 221, the motor part of the electric push rod is fixedly connected to the loading frame 33, the second screw conveyor 221 is slidably connected to the guide rail, and the chain plate type turning machine 222 is fixedly set on the loading frame 33. The electric push rod is retracted to make the second screw conveyor 221 approach or move away from the chain plate type turning machine 222. When the distance between the two is reduced, the chain plate type turning machine 222 turns the material into the second feeding port 2211 of the second screw conveyor 221; when the distance between the two is increased, the material turned by the chain plate type turning machine 222 falls back on the receiving layer 12 to loosen the material. Loosening the material can avoid material agglomeration, and can increase the gap of the material itself so that the airflow can pass through the inside of the material more easily, increase the airflow velocity, and achieve faster drying.

[0113] Example 6

[0114] Reference Figure 5 , Figure 8 .

[0115] The end of the feeding unit 2 is provided with a support frame 7, which is fixedly connected to the first screw conveyor 211, the second screw conveyor 221, and the chain plate type turner 222, and a fixed pulley 71 is provided on the support frame 7. The end of the feeding unit 2 is: the end of the feeding unit 2 away from the loading frame 33;

[0116] The drying chamber 11 is provided with a supporting guide rail 72 , and the supporting guide rail 72 is parallel to the X-guide stroke; when the feeding unit 2 is in a working state, the orthographic projections formed by the fixed pulley 71 and the supporting guide rail 72 on the receiving layer 12 overlap with each other.

[0117] The conveying unit is large in volume and heavy in mass, and has support only at one end (the connection position with the loading rack 33). Therefore, the conveying unit is prone to tilting. This has little impact on the first screw conveyor 211 and the second screw conveyor 221, but for the chain plate type turning machine 222, it will cause one end connected to the loading rack 33 to be higher and the other end to be lower, resulting in interference between the turning plates at the lower part of the chain plate type turning machine 222 and the receiving layer 12, causing the turning plates at the higher position to be unable to contact the material. In this embodiment, a support frame 7 is provided at the end of the conveying unit, and a fixed pulley 71 is provided. The fixed pulley 71 abuts against the support guide rail 72. When the X driving and guiding part drives the driving unit to move along the X guiding stroke, the fixed pulley 71 rolls on the support guide rail 72, playing a supporting role for the conveying unit. When the conveying unit enters the avoidance state, it first raises a certain distance to separate the fixed pulley 71 from the support guide rail 72, then rotates, and then raises or lowers to other drying chambers 11, and then rotates the conveying unit back into the drying chamber 11, and finally lowers a certain distance to make the fixed pulley 71 abut against the support guide rail 72.

[0118] At the same time, when the conveying unit enters the drying chamber 11 without the closing door 141, the support guide rail 72 can provide support for the conveying unit to avoid the loading rack 33 being subjected to large stress for a long time.
