Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a conveying equipment and process for producing feed additives. Background Art

[0002] Feed additive production conveying equipment is a mechanical equipment specially used for handling and moving various feed additives in the feed processing industry. They play a vital role in the entire production chain. These equipment are designed to ensure that additives can be safely, efficiently and hygienically transferred from one processing link to the next until they are finally mixed into the basic feed to achieve nutritional balance.

[0003] During the production process, feed additives often form blocks when they are piled up due to improper storage conditions or handling, and are often mixed with various impurities such as dust and debris. In order to ensure the quality of the produced feed, these impurities must be effectively removed when the raw materials are transported. The existing process mainly draws on the traditional grain processing method, that is, a blower is arranged at the end of the electric control conveyor belt, and the wind is used to blow away the impurities when the raw materials fall;

[0004] However, the methods in the existing process have exposed significant limitations in practical applications. First, a single drop removal process is difficult to ensure that the impurities in the raw materials are completely removed, because many dust and fine impurities will be tightly attached between the raw material particles and are difficult to be separated by wind during a single drop. Secondly, the cyclicity and efficiency of this method are low, and it often requires repeated operations for many times to barely achieve a certain impurity removal effect, which undoubtedly increases production costs and time costs. The dust and impurities that are not effectively removed will eventually be mixed into the basic feed, causing pollution to the feed raw materials, and further affecting the quality and safety of the entire feed product. Based on this, the present invention purposely provides a feed additive production conveying equipment and process that can effectively remove impurities in the raw materials when conveying the raw materials. Summary of the invention

[0010] The hair dryer is fixedly mounted on the base, and its air outlet faces the inside of the cylinder.

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

[0012] As a further solution of the present invention: baffles are installed at the open ends of both 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 entrance of the discharging hopper, the wide inclined plate is located below the rotating plate and is arranged at an angle, the horizontal height of the connecting end of the wide inclined plate and the discharging hopper is higher than the horizontal height of the other end thereof, when the raw materials roll down from the surface of the wide inclined plate, the falling path of the raw materials passes through the area covered by the airflow blown out by the hair dryer.

[0014] As a further solution of the present invention: a narrow inclined plate is fixedly installed at the unloading end of the wide inclined plate, the width of the narrow inclined plate is half of the width of the wide inclined plate, the narrow inclined plate is arranged obliquely, and its inclination angle is consistent with that of the wide inclined plate.

[0015] As a further solution of the present invention: a bracket is fixedly installed on the base, and a first round rod and a second round rod are installed on the bracket. The first round rod and the second round rod both extend into the cylinder and are located above the hair dryer. Dispersion components are provided on the first round rod and the second round rod, and the discharge ends of the wide inclined plate and the narrow inclined plate are both facing the dispersion components.

[0016] As a further solution of the present invention: the dispersed component includes a first long plate and a second long plate, a plurality of first long plates are fixedly installed on the first round rod and the second round rod at equal intervals, and a plurality of second long plates are fixedly installed on both of them at equal intervals, the first long plate and the second long plate are staggered, and the first long plate and the second long plate are both inclined, the horizontal height of the first long plate at the feed end is higher than the horizontal height of the discharge end, the horizontal height of the second long plate at the feed end is higher than the horizontal height of the discharge end, the angle between the wide inclined plate and the first long plate is an obtuse angle, and the angle between the wide inclined plate and the second long plate is an acute angle.

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

[0018] A conveying process for producing feed additives, the process is applied to a conveying device for producing feed additives as described above, the process comprising the following steps:

[0019] Step S1: Feed additive granular raw materials are transported into a feed barrel through a feed pipe, and a first driving source drives the blades of the feed auger to rotate to transport the granular raw materials into the barrel;

[0020] Step S2: driving the cylinder to rotate at a constant speed through the driving assembly, so that the granular raw materials continue to roll in the cylinder;

[0021] Step S3: The driving assembly drives the cylinder to rotate at a variable speed, and the rotation speed is increased in a short period of time. Under the action of centrifugal force, the granular raw materials are closely attached to the inner wall of the cylinder, and are lifted up as the cylinder rotates;

[0022] Step S4: When the level of the granular raw material is higher than the blower, the driving assembly drives the cylinder 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 out by the blower takes away the debris in the granular raw material;

[0023] Step S5: Repeat steps S3 and S4 multiple times until the granular raw material becomes clean, and then the driving component drives the cylinder to change speed and rotate, so that the clean granular raw material moves close to the inner wall of the cylinder until it moves into the discharge hopper and enters the discharge barrel. At this time, the second driving source drives the discharge auger blades to transport the granular raw material to the discharge pipe for discharge.

[0024] Beneficial effects of the present invention:

[0025] 1. In the present invention, the cylinder is rotated at a variable speed, so that the raw material moves along the inner wall of the cylinder, and when the height of the airflow blown out by the blower reaches a certain height, the cylinder resumes uniform rotation, and the centrifugal force on the raw material is less than the gravity. Under the action of gravity, the raw material and the sundries begin to fall, and the airflow blown out by the blower during the falling process is repeated for multiple times. The process of removing sundries can be performed multiple times, ensuring that the sundries can be removed thoroughly when the raw material is transported, and preventing the sundries from being mixed into the basic feed;

[0026] 2. In the present invention, when the rotating plate blocks the entrance of the discharge hopper, it ensures that the raw materials and debris will not enter the discharge hopper, avoiding the problem of incomplete impurity removal. Moreover, due to the blocking of the rotating plate, the cylinder can be kept rotating at a variable speed. The rotating plate will naturally block the raw materials and intercept them, causing the raw materials to fall. When the raw materials rebound due to the impact, the raw materials will be distributed more dispersedly, which is conducive to exposing the debris to the airflow blown by the hair dryer, which is conducive to impurity removal.

[0027] 3. In the present invention, when the raw materials are intercepted by the rotating plate, they will fall onto the wide inclined plate and then roll down along the surface of the wide inclined plate. At this time, the falling path of the raw materials passes through the area covered by the airflow blown out by the hair dryer, so that the trajectory of the falling raw materials can be guided to ensure that the airflow blown out by the hair dryer can cover the raw materials every time they fall, thereby achieving the purpose of optimizing the single impurity removal effect.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 8 As shown, the present invention is a conveying device for producing feed additives, comprising:

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

[0041] The base 3 is fixedly mounted on one side of the bearing seat 1, and a feed barrel 4 and a discharge barrel 5 are fixedly mounted thereon, the feed barrel 4 is located below the discharge barrel 5, and one end of both extends into the cylinder 2, a feed auger blade 402 is rotatably mounted in the feed barrel 4, the edge of the feed auger blade 402 is slidably matched with the inner wall of the feed barrel 4, and it is driven to rotate by the first driving source, the feed inlet of the feed barrel 4 is connected to a feed pipe 401, and the feed pipe 401 is located in the cylinder 2 outside, the discharge port of the feed cylinder 4 is located in 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 slidingly fitted with the inner wall of the discharge cylinder 5, and it is driven to rotate by the second driving source, the feed port of the discharge cylinder 5 is connected with a discharge hopper 7, the discharge hopper 7 is located in the cylinder 2, and it is fitted with the inner wall of the cylinder 2, the discharge port of the discharge cylinder 5 is connected with a discharge pipe 501, and the discharge pipe 501 is located outside the cylinder 2;

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

[0043] In one case of the present embodiment, a pulley 202 is fixedly connected to the outer circumferential surface of the cylinder 2, and the driving assembly can be a pulley assembly component driven by a motor. In this case, the pulley 202 is connected to a belt, and other mechanisms that can realize the rotation of 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 that can realize rotational motion can also be selected. This embodiment does not make specific limitations here.

[0044] The working principle of the present invention is as follows: the originally accumulated feed additive granular raw materials are transported into the feed barrel 4 through the feed pipe 401, and the feed pipe 401 pushes the raw materials in the feed barrel 4 into the cylinder 2 through the first driving source, and then the cylinder 2 is driven by the driving component to rotate at a constant speed. At this time, the cylinder 2 will drive the raw material particles to continuously roll inside it. In this process, the originally accumulated raw materials will be broken up, so that the raw materials are gradually dispersed, and the sundries mixed in the raw materials are separated. Then the driving component 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 exerted on the raw materials. Due to the effect of centrifugal force, the raw materials and debris will move along the inner wall of the cylinder 2. When the height of the raw materials is higher than the height of the airflow blown by the blower 6, the cylinder 2 resumes uniform rotation. At this time, the centrifugal force on the raw materials is less than gravity. Under the action of gravity, the raw materials and debris begin to fall. During the falling process, the airflow blown by the blower 6 will blow the debris out of the cylinder 2, thereby completing the impurity removal process. After that, the switching between uniform speed rotation and variable speed rotation of the cylinder 2 is repeated many times, and the raw materials can be subjected to multiple impurity removal processes to ensure that the debris in the additive raw materials is completely removed. Then, as shown in FIG. Figure 4 As shown in the example, the cylinder 2 is rotated at a variable speed to drive the raw materials into the discharge hopper 7, and then the raw materials enter the discharge barrel 5. The discharge auger blades 502 are driven actively by the second driving source to discharge the raw materials in the discharge barrel 5 from the discharge pipe 501, thereby completing the thorough cleaning of the debris in the raw materials when conveying the feed additive granular raw materials, and preventing the debris from eventually mixing into the basic feed.

[0045] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, a rotating plate 8 is rotatably installed at the entrance of the discharge hopper 7, and the rotating plate 8 is driven to rotate by the first output source. 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, and when one end of the rotating plate 8 rotates to be 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 may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0047] In actual application of this embodiment, the inlet of the discharge hopper 7 can be actively opened and closed by setting the rotating plate 8. Figure 3 As shown in the example, when the rotating plate 8 blocks the entrance of the discharge hopper 7, the cylinder 2 changes speed and rotates to drive the raw material to rise. When it returns to uniform motion, due to inertia, the particles will be thrown forward and may enter the discharge hopper 7. The rotating plate 8 plays a barrier role at this time to ensure that the raw material and debris will not enter the discharge hopper 7, avoiding the problem of incomplete impurity removal. In addition, due to the obstruction of the rotating plate 8, the cylinder 2 can be kept in variable speed rotation. The rotating plate 8 will naturally block the raw material and intercept it, causing the raw material to fall. When the impact causes the raw material to rebound, the raw material will be distributed more dispersedly, which is conducive to exposing the debris to the airflow blown by the blower 6, which is conducive to impurity removal.

[0048] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, baffles 201 are installed at the open ends of the cylinder 2, and the baffles 201 are detachable.

[0049] In actual application of this embodiment, firstly, the baffle 201 can prevent the raw materials in the cylinder 2 from splashing out, and secondly, the detachable design is convenient for cleaning the debris retained on the inner wall of the cylinder 2, and convenient for installing the components on the base 3 into the cylinder 2, especially the installation of the discharge hopper 7.

[0050] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, a wide inclined plate 9 is fixedly installed at the entrance of the discharging hopper 7, and the wide inclined plate 9 is located below the rotating plate 8 and is arranged obliquely. The horizontal height of the connecting end of the wide inclined plate 9 and the discharging hopper 7 is higher than the horizontal height of the other end. When the raw materials roll down from the surface of the wide inclined plate 9, the falling path of the raw materials passes through the area covered by the airflow blown out by the blower 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 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, so that 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, thereby achieving the purpose of optimizing the single-time impurity removal effect.

[0052] like Figure 5-Figure 6 As shown, as a preferred embodiment of the present invention, a narrow inclined plate 10 is fixedly installed at the unloading end of the wide inclined plate 9, and the width of the narrow inclined plate 10 is half the width of the wide inclined plate 9. The narrow inclined plate 10 is arranged obliquely, and its inclination angle is consistent with that of the wide inclined plate 9.

[0053] In actual application of this embodiment, after the raw materials roll down from the wide inclined plate 9, the raw materials will tend to be distributed roughly in a straight line. In this way, for the raw materials close to the hair dryer 6, even if the debris in the raw materials is blown away, it will be blocked by the raw materials behind. The rear raw materials are blocked by the front raw materials, and the wind force is greatly weakened when the airflow reaches the rear raw materials. Therefore, through the setting of the narrow inclined plate 10, the general raw materials of the wide inclined plate 9 are continuously 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 affected by the impurity removal effect of the strong wind.

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

[0055] In actual application of this embodiment, the dispersion component can make the falling raw material particles more dispersed, so that it is more conducive to the blower 6 to blow out the airflow to take away the debris.

[0056] like Figure 5-Figure 7 As shown, as a preferred embodiment of the present invention, the dispersed component includes a first long plate 14 and a second long plate 15, a plurality of first long plates 14 are fixedly installed on the first round rod 12 and the second round rod 13 at equal intervals, and a plurality of second long plates 15 are fixedly installed on both of them at equal intervals, the first long plates 14 and the second long plates 15 are staggered, and the first long plates 14 and the second long plates 15 are both 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 angle between the wide inclined plate 9 and the first long plate 14 is an obtuse angle, and the angle between the wide inclined plate 9 and the second long plate 15 is an acute angle.

[0057] In actual application of this embodiment, by arranging 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, and the first long plate 14 and the second long plate 15 are staggered, and the angles of the first long plate 14 and the second long plate 15 are different, and the raw materials hitting the first long plate 14 and the raw materials hitting the second long plate 15 rebound in different directions, thereby increasing the randomness of the raw material distribution. Figure 7 Instructions for small and medium arrows.

[0058] like Figure 5-Figure 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 both are driven to rotate by two second output sources respectively.

[0059] In one case of this embodiment, the second output source can be selected from components such as a servo motor, a servo motor, etc., and can also be selected from other mechanisms capable of achieving rotational motion. This embodiment does not specifically limit this.

[0060] In actual application, when the raw materials fall, the positions of the first long plate 14 and the second long plate 15 can be further changed by rotating the first round rod 12 and the second round rod 13, which makes the distribution of the granular raw materials hitting the two more irregular, which is more conducive to the removal of debris in the raw materials during the conveying process.

[0061] See also Figure 1-Figure 8 As shown, the present invention is a conveying process for producing feed additives, and the process is applied to a conveying device for producing feed additives as described in the above embodiment, and the process includes the following steps:

[0062] Step S1: Feed additive granular raw materials are transported into the feed barrel 4 through the feed pipe 401, and the first driving source drives the feed auger blade 402 to rotate to transport the granular raw materials into the cylinder 2;

[0063] Step S2: driving the cylinder 2 to rotate at a constant speed through the driving assembly, so that the granular raw materials continue to roll in the cylinder 2;

[0064] Step S3: The cylinder 2 is driven to rotate at a variable speed by the driving assembly, and the rotation speed is increased in a short time. Under the action of centrifugal force, the granular raw materials are closely attached to the inner wall of the cylinder 2, and are lifted up as the cylinder 2 rotates;

[0065] Step S4: When the level of the granular raw material is higher than the blower 6, the driving 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;

[0066] Step S5: Repeat steps S3-S4 multiple times until the granular raw material becomes clean, then the driving component drives the cylinder 2 to change speed and rotate, so that the clean granular raw material moves close to the inner wall of the cylinder 2 until it moves into the discharge hopper 7 and then enters the discharge barrel 5. At this time, the second driving source drives the discharge auger blades 502 to transport the granular raw material to the discharge pipe 501 for discharge.

[0067] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.

Under the action of centrifugal force, the granular raw materials are closely attached to the inner wall of the cylinder (2) and are 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-S4 multiple times until the granular raw material becomes clean, and then the driving component drives the cylinder (2) to change the speed of rotation, so that the clean granular raw material moves close to 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 driving source drives the discharge auger blades (502) to transport the granular raw material to the discharge pipe (501) for discharge.
