Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, specifically a distillers' grains feed screening machine. Background Technology

[0002] Byproducts such as distiller's grains are produced during the brewing process. These can be used as a high-quality feed ingredient because they contain high levels of protein and energy. After proper processing, they can be used to feed livestock and poultry such as cattle, sheep, pigs, and chickens.

[0003] However, before being processed into feed or fertilizer, the distillers' grains need to be screened to separate grains of different sizes and then processed separately. Because the distillers' grains contain a certain proportion of liquid, they are prone to clumping and are difficult to disperse and screen. At the same time, the conventional method of sorting is manual, which is inefficient, easily contaminates materials, and can also lead to incomplete sorting, thus affecting the quality of the distillers' grains.

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0041] Example 1

[0042] To fully utilize and enhance the value of distiller's grains, this embodiment provides a distiller's grains feed screening machine, see below. Figures 1-4 It includes a screening body 1, a screening box 2, and a power component 3;

[0043] The screening box 2 is movably connected to the screening body 1. The power component 3 is located on the screening body 1 and drives the screening box 2 to vibrate to screen feed. That is, the screening box 2 vibrates to screen the distillers' grains, for example, to screen out impurities such as rice husks and bone fragments. The screening efficiency is high and it is not easy to contaminate the feed.

[0044] The screening box 2 includes a box body 21 and a screen 22;

[0045] The feed inlet of the box body 21 is connected to the discharge outlet (not labeled in the figure) of the screening body 1. The screen 22 is arranged parallel inside the box body 21. The feed on the screening body 1 enters the screen 22 and is discharged through the discharge outlet on the box body 21.

[0046] The power component 3 is connected to the box body 21, and the box body 21 is driven to vibrate through the power component 3.

[0047] It should be noted that the box body 21 can be a hexahedral structure with an opening at the top, and the feed inlet of the box body 21 is one side of the opening. The screen 22 is located inside the hexahedral structure and has a gap with the top surface of the box body 21 to prevent feed from overflowing.

[0048] Furthermore, the screen 22 is provided with at least two sheets, which are arranged in parallel and spaced apart inside the box body 21 to divide the box body 21 into at least three layers in the longitudinal direction, and each layer corresponds to a discharge port;

[0049] The particle size of each layer of screen 22 gradually decreases from top to bottom to achieve layered screening, resulting in an impurity removal rate of greater than 92%.

[0050] For example, if there are two screens 22, and they are arranged in parallel and spaced apart inside the box body 21, then the box body 21 can be divided into three layers from top to bottom. Of course, the number of screens 22 can be set as needed.

[0051] To facilitate the replacement of screens 22 with different particle sizes, a screen 22 support frame 12 is provided inside the box body 21. The corresponding screen 22 can be placed on the screen 22 support frame 12 of the corresponding layer, and one screen 22 is provided on each layer of screen 22 support frame 12.

[0052] Furthermore, to prevent feed from sticking to the screen 22 and causing blockage, the surface of the screen 22 is provided with a Teflon coating or an elastic silicone layer, which extends the service life of the screen 22.

[0053] In the specific implementation process, see Figures 1-4 The screening body 1 has a first connecting shaft 11 on its inner side wall and a second connecting shaft 23 on its outer side wall. The first connecting shaft 11 and the second connecting shaft 23 are connected by a hanger 4 to support the vibration of the box body 21 under the action of the power component 3. This structural design also facilitates maintenance and replacement.

[0054] Both ends of the suspension rod 4 are sleeved on the connecting shaft on the corresponding side, so that when the box body 21 vibrates, the suspension rod 4 rotates along the connecting shaft.

[0055] In the specific implementation process, the power component 3 includes a drive component 31, a first pulley 32, a first belt 33, a vibrating wheel 34, a transmission shaft 35, an eccentric wheel 36, and a connecting rod 37;

[0056] The output end of the drive component 31 is connected to the first pulley 32. The first pulley 32, the vibrating wheel 34, the transmission shaft 35, the eccentric wheel 36, the connecting rod 37, and the box body 21 are connected in sequence. After being driven by the drive component 31, the box body 21 vibrates to screen the feed that enters the box body 21.

[0057] For example, the driving component 31 is a motor with a power of 2.2 kW and an adjustable frequency range of 0-50 Hz. The first pulley 32 is fixed on the output shaft of the motor. Therefore, the first pulley 32 rotates under the drive of the motor, and the first belt 33 drives the vibrating wheel 34 to rotate, which in turn drives the transmission shaft 35 to rotate. When the transmission shaft 35 drives the eccentric wheel 36 to rotate, the shaft on the eccentric wheel 36 drives the connecting rod 37 to reciprocate. At this time, the box body 21 connected to the connecting rod 37 also moves accordingly.

[0058] In the specific implementation process, see Figures 1-4 The lower part of the screening body 1 is provided with a support frame 12. Bearings (not labeled in the figure) and bearing seats 38 are provided on both sides of the drive shaft 35 along its axis. The bottom end of the bearing seats 38 is fixed to the support frame 12 to support the drive shaft 35. It should be noted that the two bearing seats 38 are located between the eccentric wheel 36 and the vibrating wheel 34; that is, the eccentric wheel 36 and the vibrating wheel 34 are suspended outside the support frame 12.

[0059] Furthermore, a fan 5 is provided at the lower part of the support frame 12, and a fan shaft 51 is provided on one side of the fan 5. A second pulley 6 is provided on the fan shaft 51 at the end opposite to the fan 5. The second pulley 6 is connected to the first pulley 32 through a second belt 7. The driving member 31 drives the connecting rod 37 and the fan 5 to work simultaneously. The same driving member 31 drives the movement of two structures simultaneously, which simplifies the overall structure, saves energy, and achieves synchronous operation. It can be noted that the fan shaft 51 drives the impeller inside the fan 5 to rotate synchronously to achieve the purpose of air delivery.

[0060] The air outlet of the blower 5 is connected to the air blowing channel 13 on the screening body 1 through the pipe 8, and the feed on the screening body 1 enters the box body 21 after passing through the air blowing channel 13.

[0061] In the specific implementation process, see Figures 1-4The screening body 1 also includes a support body 14 and a feeding hopper 15; the feeding hopper 15 and the box body 21 are sequentially installed on the upper part of the support body 14 along its length direction, and the feeding hopper 15 and the box body 21 are both inclined.

[0062] The discharge port of the feeding hopper 15 is located above the air blowing channel 13, and the box body 21 is located below the air blowing channel 13. The feed in the feeding hopper 15 enters the box body 21 after passing through the air blowing channel 13. For example, the discharge end of the feeding hopper 15 is higher than the inlet end of the box body 21, so that the feed flows at an angle to the lower end under the action of gravity.

[0063] To improve stability, a bearing seat 38 is provided on one of the vertical legs of the support body 14 to connect with the bearing on the fan shaft 51. The fan 5 and the drive component 31 are both located on the support rod at the lower part of the support body 14 (not labeled in the figure).

[0064] For example, the support body 14 includes two frame structures with trapezoidal longitudinal sections (including vertical support legs), which are arranged in parallel on both sides of the length direction of the feeding hopper 15, and the box body 21 is located between the two frames and is connected to the frame structure through the hanging rod 4; the lower parts of the two frame structures are connected by crossbars, which can at least support the drive component 31 and the fan 5.

[0065] The air trough 13 is opened at the lower part of the feeding hopper 15 near the box body 21. The air inlet of the air trough 13 is located at the lower part of the bottom plate of the feeding hopper 15, and the air outlet of the air trough 13 extends into the upper part of the box body 21, so that the feed is discharged from the outlet of the feeding hopper 15 and falls onto the side of the air trough 13 near the box body 21, and then enters the box body 21 for screening.

[0066] The screening machine in this embodiment can process at least 2 tons of distiller's grains with a moisture content of 65% per hour.

[0067] This utility model is implemented as follows:

[0068] Feed is added to the feeding hopper 15, and the motor is turned on at the same time, so that the blower 5 and the box body 21 work simultaneously, that is, the box body 21 vibrates while blowing air to screen the feed.

[0069] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0071] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
