Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, specifically referring to a concentrated feed processing and screening device. Background Technology

[0002] The raw materials for concentrated feed typically include various grains, protein feeds, and fat feeds. Since livestock at different growth stages require feeds of different particle sizes, screening is necessary during the processing of concentrated feed.

[0003] During the screening process of concentrated feed, equipment such as vibrating screens or vibrating cleaners can be used to separate large particles of impurities.

[0004] However, it is inconvenient to separate fine powder particles and cannot perform multi-stage screening. Utility Model Content

[0005] The technical problem to be solved by this utility model is:

[0006] Screening with a vibrating screen is not convenient for separating fine powdery particles, and has limitations.

[0007] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a concentrated feed processing and screening device, including a vibrating screen, wherein the vibrating screen is mounted on a support base;

[0008] A powder recovery assembly is installed on the upper side of the vibrating screen;

[0009] The powder recovery assembly includes a powder recovery box that is detachably installed on top of the vibrating screen and a dust collector that is fixedly installed on the vibrating screen. The dust collector is equipped with an air duct that communicates with the top of the powder recovery box, and the powder recovery box is equipped with a feed pipe that communicates with the inside of the vibrating screen.

[0010] Furthermore, a filter is installed at the connection point between the powder recovery box and the air duct.

[0011] Furthermore, the vibrating screen includes a housing mounted on a support base via a damping shock absorber, a screen mesh bolted and fixed inside the housing, a guide plate at the bottom of the screen mesh, the housing being inclined with the higher side being open and the lower side being closed at the top and forming a discharge port between the lower side and the guide plate, and a vibrator is also provided on the housing.

[0012] Furthermore, an anti-clogging component is provided on the support base and extends into the housing, located on the underside of the screen.

[0013] Furthermore, the anti-clogging component includes a transmission component, a bracket, and a brush head. The transmission component is fixedly mounted on the side of the support base near the opening of the housing. The bracket is mounted on the transmission component and extends into the housing in an L-shape. The brush head is mounted on the bracket and located below the screen.

[0014] Furthermore, the transmission assembly includes a lead screw mounting bracket fixed on the support base. A transmission motor is fixed on one side of the lead screw mounting bracket, and a screw is rotatably mounted on the other side. The transmission motor and the lead screw mounting bracket are fixedly connected. A nut-mounted slider is threaded onto the screw. The nut-mounted slider and the lead screw mounting bracket slide relative to each other. The bracket is fixed on the nut-mounted slider.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] By setting up a dust collector to collect finer powdery particles from the shell during the screening process into the powder recovery component, and then using a screen to separate particles of different sizes, a multi-stage screening effect can be achieved. Attached Figure Description

[0022] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, the present invention proposes a concentrated feed processing and screening device, which includes a vibrating screen 2, which is mounted on a support base 1.

[0025] Powder recovery assembly 4 is installed on the upper side of vibrating screen 2;

[0026] like Figure 1-2 As shown, the powder recovery assembly 4 includes a powder recovery box 5 detachably installed on top of the vibrating screen 2 and a dust collector 6 fixedly installed on the vibrating screen 2. The dust collector 6 is equipped with an air duct 7 that communicates with the top of the powder recovery box 5. The powder recovery box 5 is equipped with a feed pipe 8 that communicates with the inside of the vibrating screen 2. The concentrated feed that needs to be screened is added into the vibrating screen 2. When the vibrating screen 2 is running, the lighter powder in the feed will fly away during the vibration process. The dust collector 6 runs and sucks in the powder. The powder enters the powder recovery box 5 through the feed pipe 8.

[0027] like Figure 4 As shown, a filter 9 is installed at the connection point between the powder recovery box 5 and the air duct 7. This can prevent powder from entering the dust collector 6 and improve the service life of the dust collector 6. A discharge door is also hinged on the powder recovery box 5 to facilitate the recovery of powder after the machine stops operating.

[0028] like Figure 1 , 3 As shown, the vibrating screen 2 includes a housing 10 mounted on a support base 1 via damping shock absorbers 14. There are four damping shock absorbers 14, which are located at the four corners of the housing 10. A screen 11 is bolted and fixed inside the housing 10. The bottom of the screen 11 is a guide plate 12. The housing 10 is inclined, with the higher side being open and the lower side closed at the top and forming a discharge port 13 between the lower side and the guide plate 12. A vibrator is also provided on the housing 10. After the vibrator is running, the feed is screened on the screen 11. Small particles move along the guide plate 12 to the discharge port 13, leave the housing 10, and are recycled. Large particles remain on the screen 11. After the bolts are removed, the screen 11 is moved so that the large particles fall onto the guide plate 12 and are also recycled from the discharge port 13.

[0029] Example 2

[0030] like Figure 1 , 4As shown, if the screen 11 is not cleaned for a long time during use, it is easy to be clogged by feed, reducing the screening efficiency. Therefore, an anti-clogging component 3 is set on the support base 1 and extends into the housing 10 and is set on the lower side of the screen 11.

[0031] The anti-clogging component 3 includes a transmission component 15, a bracket 16, and a brush head 17. The transmission component 15 is fixedly installed on the side of the support base 1 near the open end of the housing 10. The bracket 16 is installed on the transmission component 15 and extends into the housing 10 in an L-shape. The brush head 17 is installed on the bracket 16 and located below the screen 11. During the vibration of the housing 10, the screen 11 will intermittently touch the brush head 17, so the brush head 17 will penetrate the holes of the screen 11 and achieve the puncturing effect.

[0032] The transmission assembly 15 includes a lead screw mounting bracket 18 fixed on the support base 1. A transmission motor 19 is fixed on one side of the lead screw mounting bracket 18, and a screw 20 is rotatably mounted on the other side. The transmission motor 19 and the lead screw mounting bracket 18 are fixedly connected. A nut-loaded slider 21 is threadedly connected to the screw 20. The nut-loaded slider 21 and the lead screw mounting bracket 18 slide relative to each other. The bracket 16 is fixed on the nut-loaded slider 21. The operation of the transmission motor 19 drives the nut-loaded slider 21 to reciprocate, thus enabling full penetration of the screen 11 and improving screening efficiency.
