[0002] Aquaculture is a production activity of artificially controlling the reproduction, cultivation and harvesting of aquatic animals and plants. Generally, it includes the whole process of cultivating aquatic products from fry under artificial feeding management. Aquaculture feed refers to special feed supplied to aquatic animals during aquaculture, which is provided as their daily food for the cultured aquatic animals. During the production process of aquaculture feed, it is necessary to mix various nutrient feeds, make various raw materials into granules, and then feed them. However, in the prior art, when making various raw materials into granules, there are often feed powders. When filtering the powders, vibrating screens and other filters are often used, which will cause the feed granules to be shattered and generate powders again. When feeding the feed, the feed powders will form a thin oil layer on the water surface to wrap the water body, causing water pollution, oxygen deficiency, etc., affecting aquaculture. Content of the Utility Model

[0003] Aiming at the above-mentioned prior art, the utility model aims to provide an aquaculture feed processing device, which can mainly filter and remove feed powders to avoid the formation of a thin layer on the water surface after feeding, resulting in water body oxygen deficiency.

[0023] Embodiment 1

[0024] Refer to the attached Figures 1-4, this application provides an aquaculture feed processing device, including a mixing and stirring device 1, a granulator 2, and a filtering and screening device 3. The discharge port of the mixing and stirring device 1 is connected to the feed inlet of the granulator 2, and the discharge port of the granulator 2 is connected to the feed inlet of the filtering and screening device 3. The mixing and stirring device 1 is used to mix and stir various raw materials evenly. The granulator 2 is used to make the raw materials stirred evenly by the mixing and stirring device 1 into granules. The mixing and stirring device 1 and the mixer are both prior arts and will not be explained in detail here. The filtering and screening device 3 includes a fixing plate 4, a sieve plate 5, an electrostatic generator 6, an electrostatic eliminator bar 7, a first electrostatic adsorption wheel 8, and a second electrostatic adsorption wheel 9. The electrostatic generator 6 is used to generate static electricity, and the electrostatic eliminator bar 7 is used to eliminate static electricity. Both sides of the sieve plate 5 are fixedly connected with the fixing plate 4. The sieve plate 5 is provided with an avoidance groove, and the avoidance groove is used to avoid the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9. The first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 pass through the avoidance groove and there is a gap left by the edge of the avoidance groove, and are rotatably connected to the fixing plate 4. Obviously, the parts of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 passing through the avoidance groove are higher than the upper surface of the sieve plate 5. The first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 both include an electrostatic partition plate 10 and an electrostatic adsorption plate 11. The electrostatic partition plate 10 is divided into several chambers around the circular axis, preferably 4 chambers. The electrostatic adsorption plate 11 is embedded in the chambers of the electrostatic partition plate 10 to form the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9. The electrostatic generator 6 is installed on the fixing plate 4 and is respectively connected to the electrostatic adsorption plates 11 of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 close to the fixing plate 4. One side of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 is provided with the electrostatic eliminator bar 7. The electrostatic eliminator bar 7 and the electrostatic generator 6 are electrically connected to a control board. The electrostatic eliminator bar 7 is also connected to an air pump through an air pipe. During operation, the electrostatic generator 6 is powered on to generate static electricity and contacts and conveys the static electricity to the uppermost electrostatic adsorption plate 11. The electrostatic adsorption plate 11 adsorbs feed powder through static electricity. Then, the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 are rotated to switch the electrostatic adsorption plates 11, so that the lower electrostatic adsorption plate 11 rotates and rotates to the upper part to contact the electrostatic generator 6 to receive static electricity and adsorb feed powder, while the electrostatic adsorption plate 11 adsorbing feed powder rotates to the lower part and separates from the electrostatic generator 6, and then passes through the electrostatic eliminator bar 7 to eliminate static electricity, so that the adsorbed feed powder drops. More preferably, the feed powder can be blown off by blowing air through the electrostatic eliminator bar 7, realizing the removal of feed powder, and the vibration during the operation of the equipment is small and does not cause the feed granules to be shattered into powder. The feed granules are driven by the rotation of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 to roll to the lower part, increasing the contact area and improving the adsorption efficiency. The structure is ingenious and the use is convenient.

One end of each of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 is fixedly connected to the driven pulley 15. The driving pulley 14 is connected to the driven pulley through the belt 18. The idler pulley 17 is rotatably connected to the mounting plate 13 and cooperates with the belt 18. The belt 18 is adjusted and pre-tightened by the idler pulley 17 on both sides of the belt 18.

The motor 16 has high power efficiency, precise control and low maintenance cost.

[0026] Preferably, the sieve device 3 further includes a rotary brush 19, a driving gear 20 and a driven gear 21.

The feed powder adsorbed by the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 is brushed off by rotating the rotary brush 19, avoiding the re-contact of the feed powder with the feed particles, and at the same time, it can also be used for the daily cleaning of the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9. The rotary brush 19 is connected to the driven gear 21 meshing with the driving gear 20. The rotary brush 19 is provided with elastic bristles 22 to improve the contact with the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9. Utilizing the power of the motor 16, the rotary brush 19 and the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 are driven to rotate in the reverse direction through the meshing transmission of the driving gear 20 and the driven gear 21, improving the cleaning efficiency, saving energy consumption, having a compact structure and being convenient for maintenance.

[0027] Preferably, the sieve device 3 further includes a vertical plate 23, a smooth rod 24, a first connecting rod 25, a second connecting rod 26, and a connecting block 27.

By loosening the screw 28, the rotation of the fixed plate 4 can be adjusted, so as to adjust the distance between the first electrostatic adsorption wheel 8 and the second electrostatic adsorption wheel 9 passing through the sieve plate 5 surface. The structure is simple and convenient to use.

The transition plate 29 is provided with a waist-shaped hole 30. Through the waist-shaped hole 30, it is convenient to adjust the locking of the fixed plate 4. The transition plate 29 is installed on both sides of the clearance groove, and is used to adjust and control the size of the gap between the first electrostatic adsorption wheel 8 (the second electrostatic adsorption wheel 9), so as to avoid the falling of feed particles due to too large a gap, and too small a gap will prevent some larger feed powders from passing through. The structure is simple and convenient to adjust.

[0030] Furthermore, the sieve device 3 further includes an adjusting seat 31 and an adjusting bolt 32. The adjusting seat 31 is installed on the fixed plate 4.
