TECHNICAL FIELD
[0001] The utility model relates to the field of feed production, and specifically relates to a feed production screening device. BACKGROUND
[0002] In today's feed production industry, with the continuous expansion of the breeding scale and the increasing demand for feed quality, the refinement of feed production, the quality of feed is directly related to the growth condition, health level and final breeding benefit of the breeding animal, and screening as an important part of the feed production process aims to accurately remove impurities in the raw materials and ensure that the feed particle size meets the standard, laying a foundation for subsequent processing and use.
[0003] The existing screening device first transports the feed raw materials to the feed inlet of the screening device through the conveying equipment, and the feed inlet is usually equipped with a flow regulating device, which can control the feeding speed according to the actual production demand, and ensure that the material enters the screening area uniformly. After entering the screening area, the feed is spread on the core screening components such as vibrating screen or rotating screen disc, and the power such as mechanical vibration, centrifugal force or airflow is used to make the feed particles meeting the particle size requirements pass through the screen, and the large particle impurities and broken particles not meeting the particle size standard are left on the screen.
[0004] The existing feed production screening device cannot quickly replace the screen with a size corresponding to the feed, and cannot quickly classify the feed of different sizes after screening, so a feed production screening device is proposed to solve the above problems. UTILITY MODEL CONTENT
[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem in the background art.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A feed production screening device of this utility model includes a workbench; a first baffle is fixedly connected above the workbench; a motor is fixedly connected to the outer side of the first baffle; a rotating shaft is fixedly connected to the end of the motor; two motors are grouped together; a screen is rotatably connected around each rotating shaft; multiple sets of screens are provided; each set of screens has first, second, and third screen holes of different sizes opened on its surface; a discharge port is fixedly connected inside the first baffle; a second baffle is fixedly connected to the side of the discharge port; multiple sets of discharge ports are provided; a trough is fixedly connected to the surface of the first baffle; the bottom of the trough... The unit is equipped with a feed inlet; the feed is screened by multiple layers of screens, allowing for multiple grading in a single screening process. This avoids the time waste caused by repeatedly screening the same material with a single screen. Each layer of screens shares the screening pressure of materials of different particle sizes. Compared to a single-layer screen bearing all the impact and friction of the material alone, the wear of each layer of the multi-layer screen is relatively small. The screens can also be replaced with different sizes. The multi-layer discharge outlet allows the material to flow down from the upper screens in sequence, quickly diverting it and classifying the feed particles of different sizes. The second baffle on the side of the discharge outlet prevents the feed from splashing around during the fall, allowing the feed to flow out along the surface of the discharge outlet.
[0007] Preferably, a first fixed seat is fixedly connected inside the first baffle; an electromagnetic vibrator is fixedly connected above the first fixed seat; there are multiple sets of electromagnetic vibrators; the surface of the electromagnetic vibrator is in frictional contact with the screen; the vibration causes the feed to continuously change position and angle on the screen surface, allowing standard small particles to pass through the screen more efficiently, dispersing the piled-up feed, avoiding material blockage in a certain place on the screen, and at the same time loosening and falling off large particles stuck at the edge of the screen holes under the action of vibration, keeping the screen transparent at all times.
[0008] Preferably, a trough is provided in the middle of the trough; a second sliding plate and the trough are slidably connected to the surface of the trough; by sliding the second sliding plate, the feed inlet is appropriately reduced and the feeding speed is slowed down for raw materials that are small and have excellent flowability, so as to prevent the raw materials from accumulating on the screen due to excessive flow and reducing the screening accuracy. If the feed is large, the feed inlet is increased so that it can enter the screening device smoothly and avoid the feed inlet from being blocked.
[0009] Preferably, a first dust-proof cloth, a second dust-proof cloth, a third dust-proof cloth, and a fourth dust-proof cloth are fixedly connected to the side of the workbench; the first dust-proof cloth, the second dust-proof cloth, the third dust-proof cloth, and the fourth dust-proof cloth are respectively arranged around the edge of the first baffle to form a wrapping; by wrapping the first dust-proof cloth around the first baffle, the dust generated during the screening process can be reduced, dust particles can be intercepted, dust can be reduced from drifting around the device, and the air in the working area can be kept relatively fresh.
[0010] Preferably, a dryer is fixedly connected to the inner side of the first baffle; a fan is rotatably connected inside the dryer; the heated air from the dryer comes into full contact with the moist feed, causing the moisture in the feed to evaporate and vaporize quickly, thus reducing the humidity of the feed and drying it. This effectively prevents the feed from becoming moldy and spoiled due to excessive moisture, which is beneficial for subsequent storage, screening, processing and other processes, and ensures the quality of the feed.
[0011] Preferably, a second fixed seat is fixedly connected inside the first baffle; a brush is fixedly connected to the surface of the second fixed seat; multiple sets of the second fixed seats are provided; the brush makes frictional contact with the second sliding plate; the brush can clean the rotating screen surface, remove blockages from the screen surface, and keep the screen in a good permeable state at all times, ensuring that standard feed particles pass through smoothly. If the material blocking the screen holes is not cleaned for a long time, it will also undergo a continuous chemical reaction with the screen, especially under the influence of humidity, temperature and other factors, accelerating the corrosion and wear of the screen.
[0012] The advantages of this utility model are:
[0013] 1. The feed production screening device of this utility model uses multiple layers of screens to screen feed during a falling process, allowing the feed to be graded multiple times in one screening process. This avoids the time waste caused by a single screen repeatedly screening the same material. Each layer of screens shares the screening pressure of materials of different particle sizes. Compared with a single layer of screens bearing all the impact and friction of all materials alone, the wear of each layer of multi-layer screens is relatively small. The screens can also be replaced with different sizes. The multi-layer discharge port allows the material to flow down from the upper screens in sequence, quickly diverting it and classifying particles of different sizes. The second baffle on the side of the discharge port can prevent the feed from splashing around during the falling process, allowing the feed to flow out along the surface of the discharge port.
[0014] 2. The feed production screening device of this utility model can reduce the dust generated during the screening process by wrapping a first dust-proof cloth around the first baffle, intercepting dust particles, reducing the dust from spreading around the device, and ensuring relatively fresh air in the working area.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figs. 1 to 5As shown in the embodiment of this utility model, a feed production screening device includes a workbench 1; a first baffle 11 is fixedly connected above the workbench 1; a motor 12 is fixedly connected to the outer side of the first baffle 11; a rotating shaft 17 is fixedly connected to the end of the motor 12; the motors 12 are grouped in pairs; a screen 13 is rotatably connected around each rotating shaft 17; multiple sets of screens 13 are provided; each set of screens 13 has a first screen hole 14, a second screen hole 15, and a third screen hole 16 of different sizes on its surface; and a discharge port 1 is fixedly connected inside the first baffle 11. 8; A second baffle 19 is fixedly connected to the side of the discharge port 18; The discharge port 18 is provided with multiple sets; A trough 111 is fixedly connected to the surface of the first baffle 11; A feed inlet 110 is opened at the bottom of the trough 111; During operation, the motor 12 is started to rotate the shaft 17, which drives the screen 13 to rotate clockwise, allowing feed of different sizes to enter the device from the feed inlet 110. The feed falls onto the surface of the screen 13 and falls downward through the first screen hole 14. Larger impurities in the feed remain above the first screen hole 14 and fall into the first discharge layer as the screen 13 rotates clockwise. Above the opening 18, feed falling from the first screen hole 14 continues to fall onto the surface of the second screen hole 15. Larger feed particles remain on the surface of the second screen hole 15. As the screen 13 rotates clockwise, the feed falls above the second discharge outlet 18. Particles smaller than those in the second screen hole 15 continue to fall and are screened on the surface of the third screen hole 16. As the screen 13 rotates, the feed falls above the third discharge outlet 18. Smaller particles eventually fall onto the surface of the worktable 1. Through multiple screens 13, the feed is screened as it falls, allowing for multiple grading in a single screening process, avoiding the problems associated with a single screen. 13. The time wasted by repeatedly screening the same material is eliminated. Each layer of screen 13 shares the screening pressure of materials of different particle sizes. Compared with a single layer of screen 13 bearing the impact and friction of all materials alone, the wear of each layer of multi-layer screen 13 is relatively small. Screen 13 can also be replaced with different sizes. Multi-layer discharge port 18 can make the material flow down from the upper screen 13 in sequence, quickly diverting it and allowing different feed particles of different sizes to be classified. The second baffle 19 on the side of the discharge port 18 can prevent the feed from splashing around during the falling process, allowing the feed to flow out along the surface of the discharge port 18.
[0025] like Figs. 1 to 2As shown in the figure, a first fixed seat 2 is fixedly connected inside the first baffle 11; an electromagnetic vibrator 21 is fixedly connected above the first fixed seat 2; there are multiple sets of electromagnetic vibrators 21; the surface of the electromagnetic vibrator 21 is in frictional contact with the screen 13; when working, the electromagnetic vibrator 21 is activated, and it vibrates against the screen 13, vibrating the feed that falls onto the surface of the screen 13. Through vibration, the feed continuously changes position and angle on the surface of the screen 13, allowing small particles that meet the standard to pass through the screen 13 more efficiently, and dispersing the feed that has piled up together, avoiding material clogging in a certain place on the screen 13. At the same time, large particles stuck at the edge of the holes of the screen 13 are loosened and fall off under the action of vibration, keeping the screen 13 transparent at all times.
[0026] like Figs. 1 to 5 As shown in the figure, a trough 32 is provided in the middle of the trough 111; a second sliding plate 31 and a first sliding plate 3 are slidably connected to the surface of the trough 32; during operation, the second sliding plate 31 can be slid to adjust the feed entry speed. By sliding the second sliding plate 31, for raw materials with fine and highly fluid feed, the feed inlet 110 can be appropriately reduced to slow down the feeding speed and prevent the raw materials from accumulating on the screen 13 due to excessive flow rate, thus reducing the screening accuracy. If the feed is large, the feed inlet 110 can be enlarged to allow it to enter the screening device smoothly and avoid clogging of the feed inlet 110.
[0027] like Figs. 1 to 5 As shown, a first dust-proof cloth 4, a second dust-proof cloth 41, a third dust-proof cloth 42, and a fourth dust-proof cloth 43 are fixedly connected to the side of the workbench 1. The first dust-proof cloth 4, the second dust-proof cloth 41, the third dust-proof cloth 42, and the fourth dust-proof cloth 43 are respectively set at the edge of the first baffle 11 to form a wrap. During operation, because the feed itself contains dust and other impurities, the dust generated during the screening process can be reduced by the first dust-proof cloth 4 wrapped around the first baffle 11, which can intercept dust particles, reduce the dust from spreading around the device, and ensure that the air in the working area is relatively fresh.
[0028] like Fig. 5 As shown, a dryer 5 is fixedly connected to the inside side of the first baffle 11; a fan 51 is rotatably connected inside the dryer 5; during operation, the dryer 5 is started, the fan 51 is rotated, and hot air is discharged, causing the internal temperature of the equipment to rise. The heated air through the dryer 5 comes into full contact with the moist feed, promoting the rapid evaporation and vaporization of moisture in the feed and the discharge of moisture from the feed, thereby achieving the purpose of reducing feed humidity and drying it, effectively preventing the feed from becoming moldy and deteriorating due to excessive moisture, which is beneficial for subsequent storage, screening, processing and other processes, and ensures feed quality.
[0029] like Figs. 1 to 5As shown in the figure, a second fixed seat 6 is fixedly connected inside the first baffle 11; a brush 61 is fixedly connected to the surface of the second fixed seat 6; multiple sets of the second fixed seat 6 are provided; the brush 61 is in frictional contact with the second sliding plate 31; during operation, due to the different sizes of feed, it may get stuck in the middle of the first screen hole 14 and the second screen hole 15 during screening. The brush 61 can clean the surface of the rotating screen 13, sweep away the blockage on the surface of the screen 13, and keep the screen 13 in a good state of permeability at all times, so that the feed particles that meet the standards can pass through smoothly. If the material blocking the holes of the screen 13 is not cleaned for a long time, it will also have a continuous chemical reaction with the screen 13, especially under the influence of humidity, temperature and other factors, which will accelerate the corrosion and wear of the screen 13.
[0030] Working principle: The motor 12 rotates the shaft 17, causing the screen 13 to rotate clockwise. Feed of different sizes enters the device through the inlet 110. The feed falls onto the surface of the screen 13 and falls downwards through the first screen hole 14. Larger impurities in the feed remain above the first screen hole 14 and fall above the first discharge outlet 18 as the screen 13 rotates clockwise. Feed falling from the first screen hole 14 continues to fall onto the surface of the second screen hole 15. Larger particles remain on the surface of the second screen hole 15 and fall above the second discharge outlet 18 as the screen 13 rotates clockwise. Particles smaller than those in the second screen hole 15 continue to fall and are screened on the surface of the third screen hole 16. As the screen 13 rotates, the feed falls above the third discharge outlet 18. Smaller particles eventually fall onto the surface of the worktable 1. The electromagnetic vibrator 21 is activated, vibrating against the screen 13 to agitate the feed particles falling onto the screen 13. The feed vibrates, causing it to continuously change position and angle on the surface of the screen 13. The second sliding plate 31 can be slidable to adjust the feed entry speed. For feeds that are small and have excellent flowability, the feed inlet 110 can be appropriately reduced by sliding the second sliding plate 31 to slow down the feeding speed. During the screening process, since the feed itself contains dust and other impurities, the first dust-proof cloth 4 wrapped around the first baffle 11 can reduce the dust generated during the screening process, intercept dust particles, and reduce the dust from spreading around the device. The dryer 5 is started, and the fan 51 is rotated to exhaust hot air, raising the internal temperature of the equipment. The heated air in the dryer 5 can fully contact the moist feed. Since the feed is of different sizes, it may get stuck in the middle of the first screen hole 14 and the second screen hole 15 during screening. The brush 61 can be used to clean the surface of the rotating screen 13 and remove the blockage.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
