Abstract

The present invention relates to the technical field of conveying equipment, and discloses a conveying equipment and process for feed additive production, including: a bearing seat, on which a cylinder is rotatably installed, and the cylinder is driven by a driving component to rotate at a variable speed; a base, which is fixedly installed on one side of the bearing seat, and on which a feed cylinder and a discharge cylinder are fixedly installed, and the feed cylinder is located below the discharge cylinder. In the present invention, through the variable-speed rotation of the cylinder, the raw materials will move along the inner wall of the cylinder.

Repeating the variable-speed and uniform rotation multiple times like this can make the raw materials pass through the area covered by the air flow multiple times, thereby carrying out the process of impurity removal multiple times, ensuring thorough impurity removal when conveying the raw materials, and avoiding the final mixing of sundries into the basic feed.

Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly relates to a conveying equipment and process for feed additive production. Background Art

[0002] The conveying equipment for feed additive production is a mechanical equipment specifically used to process and move various feed additives in the feed processing industry. They play a crucial role in the entire production chain. The design of these equipment aims to ensure that the additives can be safely, efficiently, and hygienically transferred from one processing link to the next until finally mixed into the basic feed to achieve the purpose of nutritional balance.

[0003] During the production process of feed additives, they often agglomerate and form lumps when piled up due to improper storage conditions or handling, and are often mixed with various impurities such as dust and debris. To ensure the excellent quality of the produced feed, these sundries must be effectively removed when transporting the raw materials. In the existing process, the traditional grain processing method is mainly borrowed, that is, a blower is configured at the end of the electrically controlled conveyor belt. During the process of the raw materials falling, the sundries are blown away by the wind force.

[0004] However, the method in the existing process exposes significant limitations in practical applications. First of all, the single falling impurity removal process is difficult to ensure that the sundries in the raw materials are completely removed, because many dusts and fine impurities will adhere tightly between the raw material particles and are difficult to be separated by the wind force during a single fall. Secondly, the cyclicity and efficiency of this method are low, and multiple repeated operations are often required to barely achieve a certain impurity removal effect, which undoubtedly increases the production cost and time cost. And the dust and impurities that are not effectively removed will eventually be mixed into the basic feed, polluting the feed raw materials and thus affecting the quality and safety of the entire feed product. Based on this, the present invention purposefully provides a conveying equipment and process for feed additive production that can effectively remove impurities in the raw materials when transporting the raw materials. Summary of the Invention

[0005] The purpose of the present invention is to provide a conveying equipment and process for feed additive production in view of the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A conveying equipment for feed additive production, comprising:

[0008] A bearing seat, on which a cylinder is rotatably installed, and the cylinder is driven by a driving component to rotate at a variable speed;

[0009] A base, which is fixedly installed on one side of a carrier seat, and an inlet tube and an outlet tube are fixedly installed thereon. The inlet tube is located below the outlet tube, and one ends of both of them extend into a cylinder. An inlet auger blade is rotatably installed in the inlet tube. The edge of the inlet auger blade is slidably engaged with the inner wall of the inlet tube, and it is driven by a first driving source to rotate. The inlet of the inlet tube is communicated with a feed pipe, and the feed pipe is located outside the cylinder. The outlet of the inlet tube is located inside the cylinder. An outlet auger blade is rotatably installed in the outlet tube. The edge of the outlet auger blade is slidably attached to the inner wall of the outlet tube, and it is driven by a second driving source to rotate. The inlet of the outlet tube is communicated with an outlet hopper. The outlet hopper is located inside the cylinder and is attached to the inner wall of the cylinder. The outlet of the outlet tube is communicated with an outlet pipe, and the outlet pipe is located outside the cylinder;

[0010] A hair dryer, which is fixedly installed on the base, and its air outlet faces inside the cylinder.

[0011] As a further solution of the present invention: a rotating plate is rotatably installed at the inlet of the outlet hopper. The rotating plate is driven by a first output source to rotate. When one end of the rotating plate rotates to be close to the inner wall of the cylinder, the inlet of the outlet hopper is blocked at this time. When one end of the rotating plate rotates away from the inner wall of the cylinder, the inlet of the outlet hopper is opened at this time.

[0012] As a further solution of the present invention: baffles are installed at both open ends of the cylinder, and the baffles are detachable.

[0013] As a further solution of the present invention: a wide inclined plate is fixedly installed at the inlet of the outlet hopper. The wide inclined plate is located below the rotating plate and is inclined. The horizontal height of the connection end of the wide inclined plate and the outlet hopper is higher than the horizontal height of its other end. When the raw material rolls down from the plate surface of the wide inclined plate, the falling path of the raw material passes through the area covered by the air flow blown by the hair dryer.

[0014] As a further solution of the present invention: a narrow inclined plate is fixedly installed at the discharging end of the wide inclined plate. The width of the narrow inclined plate is half of the width of the wide inclined plate. It is inclined and has the same inclination angle as the wide inclined plate.

[0015] As a further solution of the present invention: a support is fixedly installed on the base. A first round rod and a second round rod are installed on the support. Both the first round rod and the second round rod extend into the cylinder and are located above the hair dryer. There are dispersion components on both the first round rod and the second round rod. The discharging ends of the wide inclined plate and the narrow inclined plate both face the dispersion components.

[0016] As a further solution of the present invention: The dispersion component includes a first long plate and a second long plate. A plurality of first long plates are fixedly installed at equal intervals on the first round rod and the second round rod, and a plurality of second long plates are fixedly installed at equal intervals on both of them. The first long plates and the second long plates are arranged in a staggered manner. Both the first long plate and the second long plate are inclined. The horizontal height of the feeding end of the first long plate is higher than the horizontal height of the discharging end. The horizontal height of the feeding end of the second long plate is higher than the horizontal height of the discharging end. The included angle between the wide inclined plate and the first long plate is an obtuse angle, and the included angle between the wide inclined plate and the second long plate is an acute angle.

[0017] As a further solution of the present invention: Both the first round rod and the second round rod are rotatably installed on the bracket, and the two are respectively driven to rotate by two second output sources.

[0018] A conveying process for the production of feed additives, which is applied to a conveying device for the production of feed additives as described above. The process includes the following steps:

[0019] Step S1: Convey the granular raw materials of feed additives into the feeding cylinder through the feeding pipe. The first driving source drives the feeding auger blade to rotate, and conveys the granular raw materials into the cylinder.

[0020] Step S2: Drive the cylinder to rotate at a constant speed through the driving component, so that the granular raw materials continuously tumble in the cylinder.

[0021] Step S3: Drive the cylinder to rotate at a variable speed through the driving component, and increase the rotation speed in a short time. Under the action of centrifugal force, the granular raw materials cling to the inner wall of the cylinder and are lifted to a high level as the cylinder rotates.

[0022] Step S4: When the horizontal height of the granular raw materials is higher than that of the hair dryer, the driving component drives the cylinder to rotate at a constant speed, and the centrifugal force decreases. Under the action of gravity, the granular raw materials fall, and the air flow blown out by the hair dryer takes away the sundries in the granular raw materials during the falling process.

[0023] Step S5: Repeat steps S3 - S4 multiple times until the granular raw materials become clean. Then the driving component drives the cylinder to rotate at a variable speed, so that the clean granular raw materials move close to the inner wall of the cylinder until they move into the discharge hopper and then enter the discharge cylinder. At this time, the second driving source drives the discharge auger blade to convey the granular raw materials to the discharge pipe for discharge.

[0024] The beneficial effects of the present invention:

[0025] 1. In the present invention, through the variable-speed rotation of the cylinder, the raw materials will move along the inner wall of the cylinder. When the height of the air flow blown by the hair dryer is reached, the cylinder then resumes uniform rotation. At this time, the centrifugal force acting on the raw materials is less than the gravitational force. Under the action of gravity, the raw materials and impurities start to fall. During the falling process, they pass through the air flow blown by the hair dryer. By repeating the variable-speed and uniform rotation multiple times, the process of impurity removal can be carried out multiple times, ensuring thorough impurity removal during the transportation of raw materials and preventing impurities from ultimately mixing into the basic feed.

[0026] 2. In the present invention, when the rotating plate blocks the inlet of the discharge hopper, it ensures that the raw materials and impurities do not enter the discharge hopper, avoiding the problem of incomplete impurity removal. Moreover, due to the blocking of the rotating plate, the cylinder can always maintain variable-speed rotation. Naturally, the rotating plate will block the raw materials and intercept them, causing the raw materials to fall. When the raw materials rebound due to the impact, they will be more dispersed, which is conducive to the exposure of impurities in the air flow blown by the hair dryer and facilitates the impurity removal process.

[0027] 3. In the present invention, when the raw materials are intercepted by the rotating plate and fall onto the wide inclined plate, they will roll along the surface of the wide inclined plate. At this time, the falling path of the raw materials passes through the coverage area of the air flow blown by the hair dryer. In this way, the trajectory of the falling raw materials can be guided, ensuring that the air flow blown by the hair dryer can cover the raw materials every time they fall, achieving the best single-time impurity removal effect.

Detailed implementation manner

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] Please refer to Figures 1-8 As shown, the present invention is a conveying device for the production of feed additives, including:

[0040] A bearing seat 1, on which a cylinder 2 is rotatably installed, and the cylinder 2 is driven by a driving component to rotate at a variable speed;

[0041] A base 3, which is fixedly installed on one side of the bearing seat 1, and a feed cylinder 4 and a discharge cylinder 5 are fixedly installed thereon. The feed cylinder 4 is located below the discharge cylinder 5, and one ends of both extend into the cylinder 2. A feed auger blade 402 is rotatably installed in the feed cylinder 4. The edge of the feed auger blade 402 is slidably matched with the inner wall of the feed cylinder 4, and it is driven by a first driving source to rotate. The feed inlet of the feed cylinder 4 is communicated with a feed pipe 401, and the feed pipe 401 is located outside the cylinder 2. The discharge outlet of the feed cylinder 4 is located inside the cylinder 2. A discharge auger blade 502 is rotatably installed in the discharge cylinder 5. The edge of the discharge auger blade 502 is slidably attached to the inner wall of the discharge cylinder 5, and it is driven by a second driving source to rotate. The feed inlet of the discharge cylinder 5 is communicated with a discharge hopper 7. The discharge hopper 7 is located inside the cylinder 2 and is attached to the inner wall of the cylinder 2. The discharge outlet of the discharge cylinder 5 is communicated with a discharge pipe 501, and the discharge pipe 501 is located outside the cylinder 2;

[0042] A hair dryer 6, which is fixedly installed on the base 3, and its air outlet faces the inside of the cylinder 2.

[0043] In one case of this embodiment, a pulley 202 is fixedly connected to the outer circumferential surface of the cylinder 2. The driving assembly can be a pulley assembly driven by a motor. At this time, the pulley 202 is connected to a belt. Other mechanisms capable of rotating the cylinder 2 can also be selected. The first driving source and the second driving source can both be servo motors, servo motors and other components, and other mechanisms capable of realizing rotational motion can also be selected. This embodiment does not make specific limitations here.

[0044] The working principle of the present invention: The originally stacked feed additive granular raw materials are conveyed into the feed cylinder 4 through the feed pipe 401. The first driving source causes the feed pipe 401 to push the raw materials in the feed cylinder 4 into the cylinder 2, and then the driving assembly drives the cylinder 2 to rotate at a constant speed. At this time, the cylinder 2 will drive the raw material particles to continuously tumble inside it. In this process, the originally stacked raw materials will be scattered, so that the raw materials are gradually dispersed, and the sundries mixed in the raw materials are separated. Then the driving assembly drives the cylinder 2 to rotate at a variable speed, that is, to increase the speed. At this time, the centrifugal force will be greater than the gravity of the raw materials. Due to the action of the centrifugal force, the raw materials and sundries will move along the inner wall of the cylinder 2. When the height of the raw materials is higher than the height of the air flow blown by the hair dryer 6, the cylinder 2 resumes uniform rotation. At this time, the centrifugal force received by the raw materials is less than the gravity. Under the action of gravity, the raw materials and sundries begin to fall. During the falling process, they pass through the air flow blown by the hair dryer 6, and the air flow will blow the sundries out of the cylinder 2, thus completing the impurity removal process. After that, the switching between the uniform rotation and variable speed rotation of the cylinder 2 is repeated multiple times, and the raw materials can be subjected to multiple impurity removal processes to ensure that the sundries in the additive raw materials are completely removed. Then, as Figure 4 shown as an example, the cylinder 2 is driven to rotate at a variable speed, driving the raw materials into the discharge hopper 7. Subsequently, the raw materials will enter the discharge cylinder 5. The second driving source drives the discharge auger blade 502 to rotate actively, and discharges the raw materials in the discharge cylinder 5 from the discharge pipe 501, thus completing the thorough cleaning of the sundries in the raw materials when transporting the feed additive granular raw materials, and avoiding the sundries from finally mixing into the basic feed.

[0045] As Figures 1-6 shown, as a preferred embodiment of the present invention, a rotating plate 8 is rotatably installed at the entrance of the discharge hopper 7. The rotating plate 8 is driven by a first output source to rotate. When one end of the rotating plate 8 rotates to be close to the inner wall of the cylinder 2, the entrance of the discharge hopper 7 is blocked. When one end of the rotating plate 8 rotates away from the inner wall of the cylinder 2, the entrance of the discharge hopper 7 is opened.

[0046] In one case of this embodiment, the first output source can be a servo motor, a servo motor and other components, and other mechanisms capable of realizing rotational motion can also be selected. This embodiment does not make specific limitations here.

[0047] In actual application of this embodiment, through the setting of the rotating plate 8, the inlet of the discharge hopper 7 can be actively opened and closed. For example, Figure 3 As shown in the figure, when the rotating plate 8 blocks the inlet of the discharge hopper 7, at this time, the cylinder 2 rotates at a variable speed, driving the raw materials to rise. When it returns to uniform motion, due to inertia, the particles will be thrown forward and may enter the discharge hopper 7. At this time, the rotating plate 8 plays a role of blocking, ensuring that the raw materials and sundries will not enter the discharge hopper 7, avoiding the problem of incomplete impurity removal. Moreover, due to the blocking of the rotating plate 8, the cylinder 2 can always rotate at a variable speed. Naturally, the rotating plate 8 will block the raw materials and intercept them, causing the raw materials to fall. When the raw materials bounce due to the impact, the raw materials will be more dispersed, which is conducive to the sundries being exposed to the airflow blown by the hair dryer 6, facilitating impurity removal.

[0048] For example, Figures 1-5 As shown in the figure, as a preferred embodiment of the present invention, baffles 201 are installed at both open ends of the cylinder 2, and the baffles 201 are detachable.

[0049] In actual application of this embodiment, first, the baffle 201 can block the raw materials in the cylinder 2 from splashing out. Secondly, the detachable design facilitates the cleaning of the sundries remaining on the inner wall of the cylinder 2, and also facilitates the installation of the components on the base 3 into the cylinder 2, especially the installation of the discharge hopper 7.

[0050] For example, Figures 1-6 As shown in the figure, as a preferred embodiment of the present invention, a wide inclined plate 9 is fixedly installed at the inlet of the discharge hopper 7. The wide inclined plate 9 is located below the rotating plate 8 and is inclined. The horizontal height of the connection end of the wide inclined plate 9 with the discharge hopper 7 is higher than the horizontal height of its other end. When the raw materials roll down from the plate surface of the wide inclined plate 9, the falling path of the raw materials passes through the area covered by the airflow blown by the hair dryer 6.

[0051] In actual application of this embodiment, when the raw materials are intercepted by the rotating plate 8, they will fall onto the wide inclined plate 9 and then roll down along the plate surface of the wide inclined plate 9. At this time, the falling path of the raw materials passes through the area covered by the airflow blown by the hair dryer 6. In this way, the trajectory of the falling raw materials can be guided to ensure that the airflow blown by the hair dryer 6 can cover the raw materials every time they fall, achieving the purpose of the best single impurity removal effect.

[0052] For example, Figures 5-6 As shown in the figure, as a preferred embodiment of the present invention, a narrow inclined plate 10 is fixedly installed at the discharging end of the wide inclined plate 9. The width of the narrow inclined plate 10 is half of the width of the wide inclined plate 9. It is inclined and has the same inclination angle as the wide inclined plate 9.

[0053] In actual application of this embodiment, after the raw materials roll off the wide inclined plate 9, the raw materials will roughly tend to be distributed in a straight line. In this way, for the raw materials close to the hair dryer 6, even if the sundries in the raw materials are blown away, they will be blocked by the subsequent raw materials. And due to the blockage of the previous raw materials, the wind force is greatly weakened when the air flow reaches the subsequent raw materials. Therefore, through the setting of the narrow inclined plate 10, the raw materials on the wide inclined plate 9 are further guided and fall from the narrow inclined plate 10, so that the positions of the raw materials falling from the wide inclined plate 9 and the raw materials falling from the narrow inclined plate 10 are staggered, so that both can be subjected to the impurity removal effect of strong wind force.

[0054] As Figures 1-8 shown, as a preferred embodiment of the present invention, a bracket 11 is fixedly installed on the base 3, a first round rod 12 and a second round rod 13 are installed on the bracket 11, both the first round rod 12 and the second round rod 13 extend into the cylinder 2, and they are located above the hair dryer 6. There are dispersion components on both the first round rod 12 and the second round rod 13, and the feeding ends of the wide inclined plate 9 and the narrow inclined plate 10 both face the dispersion components.

[0055] In actual application of this embodiment, through the dispersion component, the falling raw material particles can be made more dispersed, so that it is more conducive for the air flow blown by the hair dryer 6 to take away the sundries.

[0056] As Figures 5-7 shown, as a preferred embodiment of the present invention, the dispersion component includes a first long plate 14 and a second long plate 15. A plurality of first long plates 14 are equally spaced and fixedly installed on both the first round rod 12 and the second round rod 13, and a plurality of second long plates 15 are equally spaced and fixedly installed on both of them. The first long plate 14 and the second long plate 15 are staggeredly distributed. Both the first long plate 14 and the second long plate 15 are inclined. The horizontal height of the feeding end of the first long plate 14 is higher than the horizontal height of the discharging end. The horizontal height of the feeding end of the second long plate 15 is higher than the horizontal height of the discharging end. The included angle between the wide inclined plate 9 and the first long plate 14 is an obtuse angle, and the included angle between the wide inclined plate 9 and the second long plate 15 is an acute angle.

[0057] In actual application of this embodiment, through the arrangement of the first long plate 14 and the second long plate 15, the raw materials falling from the wide inclined plate 9 and the narrow inclined plate 10 will hit the first long plate 14 and the second long plate 15. The first long plate 14 and the second long plate 15 are staggeredly arranged, and the angles of the first long plate 14 and the second long plate 15 are different, and the rebounding directions of the raw materials hitting the first long plate 14 and the raw materials hitting the second long plate 15 are different. In this way, the randomness of the raw material distribution is increased, specifically as Figure 7 indicated by the small arrows in

[0058] As Figures 5-8As shown, as a preferred embodiment of the present invention, the first round rod 12 and the second round rod 13 are both rotatably mounted on the bracket 11, and the two are respectively driven by two second output sources to rotate.

[0059] In one case of this embodiment, the second output source can be selected from components such as servo motors and servo motors, and other mechanisms capable of realizing rotational motion can also be selected. This embodiment does not make specific limitations here.

[0060] In the actual application of this embodiment, when the raw materials fall, through the rotation of the first round rod 12 and the second round rod 13, the positions of the first long plate 14 and the second long plate 15 can be further changed, which makes the particulate raw materials hitting the two more irregularly distributed, and is more conducive to removing impurities in the raw materials during the process of transporting the raw materials.

[0061] Please refer to Figures 1-8 As shown, the present invention is a conveying process for the production of feed additives. The process is applied to a conveying device for the production of feed additives as described in the above embodiment. The process includes the following steps:

[0062] Step S1: Convey the particulate raw materials of the feed additive into the feed cylinder 4 through the feed pipe 401, and the first drive source drives the feed auger blade 402 to rotate to convey the particulate raw materials into the cylinder 2;

[0063] Step S2: Drive the cylinder 2 to rotate at a constant speed through the drive assembly, so that the particulate raw materials continuously tumble in the cylinder 2;

[0064] Step S3: Drive the cylinder 2 to rotate at a variable speed through the drive assembly, increase the rotation speed in a short time. Under the action of centrifugal force, the particulate raw materials are close to the inner wall of the cylinder 2 and are lifted to a high level as the cylinder 2 rotates;

[0065] Step S4: When the horizontal height of the particulate raw materials is higher than the blower 6, the drive assembly drives the cylinder 2 to rotate at a constant speed, the centrifugal force decreases, and under the action of gravity, the particulate raw materials fall. During the falling process, the airflow blown out by the blower 6 takes away the impurities in the particulate raw materials;

[0066] Step S5: Repeat steps S3 - step S4 multiple times until the particulate raw materials become clean. Then, the drive assembly drives the cylinder 2 to rotate at a variable speed, so that the clean particulate raw materials move close to the inner wall of the cylinder 2 until they move into the discharge hopper 7 and then into the discharge cylinder 5. At this time, the second drive source drives the discharge auger blade 502 to convey the particulate raw materials to the discharge pipe 501 for discharge.

[0067] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made in accordance with the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.

A conveying process for the production of feed additives, characterized in that: The process is applied to a conveying device for producing feed additives as described in any one of claims 1 to 5, and the process comprises the following steps: Step S1: Feed additive granular raw materials are conveyed into the feed barrel (4) through the feed pipe (401), and the first driving source drives the feed auger blades (402) to rotate to convey the granular raw materials into the cylinder (2); Step S2: driving the cylinder (2) to rotate at a constant speed by means of a driving component, so that the granular raw material continues to roll inside the cylinder (2); Step S3: driving the cylinder (2) to rotate at a variable speed through the driving assembly, increasing the rotation speed in a short period of time, so that under the action of centrifugal force, the granular raw material clings to the inner wall of the cylinder (2) and is lifted up as the cylinder (2) rotates; Step S4: when the level of the granular raw material is higher than the blower (6), the drive assembly drives the cylinder (2) to rotate at a constant speed, the centrifugal force decreases, and the granular raw material falls under the action of gravity. During the falling process, the airflow blown by the blower (6) takes away the debris in the granular raw material; Step S5: Repeat steps S3 and S4 multiple times until the granular raw material becomes clean, then the drive assembly drives the cylinder (2) to rotate at a variable speed, so that the clean granular raw material moves closely against the inner wall of the cylinder (2) until it moves into the discharge hopper (7) and enters the discharge barrel (5). At this time, the second drive source drives the discharge auger blades (502) to transport the granular raw material to the discharge pipe (501) for discharge.
