Description

Technical Field

[0001] This utility model relates to the field of feed technology, specifically to a feed impurity removal machine. Background Technology

[0002] During feed production, animal protein raw materials such as fishmeal and meat and bone meal are often mixed with poultry and livestock feathers due to defects in processing technology. When this type of feed is fed, the keratin structure contained in the feathers is special and difficult for livestock such as chickens and ducks to digest and absorb, resulting in a significant reduction in the utilization rate of effective nutrients in the feed. In addition, the feathers may carry pathogens such as avian influenza virus and Salmonella, which may cause the spread of diseases in the breeding industry and increase the risk of breeding. Therefore, feed impurity removal machines are generally used to separate the feathers.

[0003] However, in actual operation, especially in hot and humid areas, feathers become more flexible after absorbing moisture and are easily tangled into fluff. At the same time, feed pellets become stickier due to moisture absorption, making them easy to form sticky clumps with feathers that are difficult to separate. Utility Model Content

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 This utility model provides a technical solution: a feed impurity removal machine, including a body 1, a feeding cylinder 2, a conveyor belt 3, and a debris collection box 4. The feeding cylinder 2 is located at the top of the body 1, the conveyor belt 3 is located at the bottom of the body 1, and the debris collection box 4 is located on the side of the body 1. A sieve box 5 is obliquely arranged inside the body 1. Connecting ropes 6 are installed between the four corners of the sieve box 5 and the inner wall of the body 1. A rotating rod 7 is rotatably installed at one end of the sieve box 5 near the lower half of the body 1. A turntable 8 is rotatably installed inside the body 1. The end of the rotating rod 7 away from the sieve box 5 is movably installed at the edge of the turntable 8. A fly guard 9 is detachably installed on the top of the sieve box 5 near the rotating rod 7. A wind sieve assembly is provided between the body 1 and the sieve box 5 to blow feathers off the surface of the feed inside the sieve box 5.

[0026] It also includes a guide pipe 10 that is obliquely fixedly installed below the machine body 1. The opening of the guide pipe 10 is located obliquely above the sieve box 5. A heating ring 11 is fixedly installed on the outer periphery of one end of the guide pipe 10 near the sieve box 5. The machine body 1 is equipped with a separation component for breaking up agglomerated feed.

[0027] Furthermore, the separation assembly includes a rotating rod 12 rotatably installed inside the machine body 1. Multiple separation blades 13 are fixedly installed on the rotating rod 12 near the top of the machine body 1. A collection hose 14 is provided on the surface of the machine body 1 below the feeding cylinder 2.

[0028] Furthermore, multiple separation blades 13 are arranged in an array around the rotating rod 12 as the axis, and each of the multiple separation blades 13 is provided with an electrostatic brush.

[0029] In this embodiment, controlling the rotation of the rotating rod 12 drives the separation blades 13 to rotate, which in turn contact with the agglomerated feed to generate mechanical energy such as shearing, squeezing, and friction, breaking up the agglomerates and dispersing the feed particles evenly. In addition, the electrostatic brushes on the surface of the separation blades 13 can specifically adsorb and peel off the feathers on the surface of the feed. Then, the dispersed feed is guided through the guide pipe 10 and heated and dried by the heating ring 11. At the same time, it falls obliquely into the sieve box 5. Since the sieve box 5 is designed at an angle inside the machine body 1, when the feed falls into the sieve box 5, the rotation of the turntable 8 drives the sieve box 5 on the rotating rod 7 to move back and forth. The feed will make a projectile motion on the sieve box 5, thereby further dispersing the agglomerated feed. The dispersed feed will fall onto the surface of the conveyor belt 3 through the sieve holes on the sieve box 5 for sieving.

[0030] Please see Figure 4 and Figure 5 The present invention provides a technical solution: further, the air screening assembly includes a collection hose 14 connecting the screening box 5 and the debris collection box 4. The collection hose 14 is located below the anti-flying plate 9. A separation nozzle 15 is fixedly installed on the side of the screening box 5 away from the collection hose 14. An inlet and outlet are opened on the surface of the machine body 1 corresponding to the moving part of the conveyor belt 3. A secondary air screening component is provided at the outlet of the machine body 1 corresponding to the moving part of the conveyor belt 3 for secondary separation of fine feathers on the surface of the conveyor belt 3.

[0031] Furthermore, the nozzle of the separating nozzle 15 forms an angle with the feed surface inside the sieve box 5, and the nozzle direction of the separating nozzle 15 is directly opposite the opening of the collecting hose 14.

[0032] Furthermore, the secondary air screening component includes a support block 16 fixedly installed above the conveyor belt 3, an adsorption plate 17 slidably installed inside the support block 16, and a gentle air nozzle 18 fixedly installed on the surface of the machine body 1 corresponding to the outlet of the conveyor belt 3.

[0033] Furthermore, the adsorption plate 17 is composed of two parts: a fluff adsorption layer 171 and a smoothing layer 172. The fluff adsorption layer 171 and the smoothing layer 172 are closely attached to each other. The fluff adsorption layer 171 is located on the side closer to the body 1. The fluff adsorption layer 171 is made of a flexible material with adhesive properties.

[0034] This embodiment uses the design of a gentle air nozzle 18 and a fluff adsorption layer 171. By designing a gentle air nozzle 18 at the outlet of the feed transported by the conveyor belt 3, and using the fluff adsorption layer 171, fine fiber feathers are blown up and then adsorbed by the surface of the fluff adsorption layer 171, thus performing a secondary air sieving of the feed.

[0035] Working Principle: When using this feed impurity remover in hot and humid areas, the feed can be first put into the feeding cylinder 2. At this time, by controlling the rotation of the rotating rod 12, the separating blades 13 can be rotated, which contact the agglomerated feed and generate mechanical energy such as shearing, squeezing and friction, breaking up the agglomerates and making the feed particles evenly dispersed. In addition, the electrostatic brushes on the surface of the separating blades 13 can specifically adsorb and peel off the feathers on the surface of the feed. Then, the dispersed feed is guided through the guide pipe 10 and heated and dried by the heating ring 11. It falls obliquely into the screening box 5. At the same time, the screening box 5 is in the machine. The body 1 is designed at an angle, so when the feed falls into the screening box 5, the rotation of the turntable 8 drives the screening box 5 on the rotating rod 7 to move back and forth. The feed will be projected on the screening box 5, and the cohesive feed will be further dispersed. The dispersed feed will fall onto the surface of the conveyor belt 3 through the screen holes on the screening box 5, while the feathers will move to the lower side of the screening box 5 under the influence of vibration. Then the separation nozzle 15 is activated to blow the feathers here into the collection hose 14 for collection. This can achieve efficient separation and collection of feather impurities, and initially ensure the purity of the feed.

[0036] In addition, considering that this method is good at screening large debris feathers, but inevitably misses fine fiber feathers adsorbed on the surface of the feed, the design of the gentle air nozzle 18 and the down adsorption layer 171 is adopted. By designing the gentle air nozzle 18 at the outlet of the feed transported by the conveyor belt 3, and using the down adsorption layer 171, the fine fiber feathers are blown up and then adsorbed by the surface of the down adsorption layer 171, and the feed is subjected to secondary air screening. This method can capture the residual fine fiber feathers, and the whole system forms a multi-stage impurity removal system of "mechanical dispersing - vibrating screening + air screening - air secondary adsorption screening", which further improves the purity of the feed and effectively reduces the decrease in feed utilization and the risk of aquaculture diseases caused by feather residue.

[0037] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
