[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Referring to the accompanying drawings, a feed processing device includes a raw material cleaning and impurity removal mechanism 10, a raw material crushing mechanism 20, a silo part 30, a mixing mechanism 40, and a granulating mechanism 50 which are sequentially arranged from top to bottom. The mixing mechanism 40 includes a mixing bag 41 arranged below each silo opening of the silo part 30. The raw material crushing mechanism 20 includes first and second raw material crushers 21 and 22 which are sequentially arranged. The silo part 30 includes first and second silos 31 and 32. The discharge port of the first raw material crusher 21 is connected to the first The feed port of the silo 31 and the discharge port of the second raw material crusher 22 are connected to the feed port of the second silo 32. The granulating mechanism 50 includes a single-material granulator 51 and a mixing granulator 52. The discharge port of the first silo 31 is connected to the single-material granulator 51. The mixing mechanism 40 also includes a mixing pipe 42 placed horizontally below the mixing bag 41 below the second silo 32. The discharge port of the mixing bag 41 below the second silo 32 is connected to the mixing pipe 42, and the mixing pipe 42 is connected to the hopper of the mixing granulator 52 below.

[0018] The present invention has the multifunctional processing effects of crushing, mixing and granulating a single material and crushing, mixing and granulating a mixed material, and the mixed material is mixed by a large mixing from the second silo 32 to the mixing bag 41 below it, and then the large mixed materials are mixed again by the mixing pipe 42 and collected and concentrated before being transferred to the mixing granulator 52. The use of such a two-stage mixing structure has beneficial effects: first, it avoids the large mixing of multiple materials directly transferred to the hopper of the mixing granulator 52, and the hopper load is too large, resulting in reduced operating efficiency of the mixing granulator 52. (The applicant further explains this point, that is, if the mixing materials below the silos of the second silo 32 are mixed, the mixing materials are mixed again, and the mixing materials are mixed again. The discharge port of the bag 41 directly discharges the material to the hopper of the mixing granulator 52. The input of the mixing granulator 52 may be overloaded, which leads to a decrease in the operating efficiency of the mixing granulator 52. The mixing pipe 42 arranged at the lower level of the mixing bag 41 below the second silo 32 is equivalent to a buffer for the input transferred to the hopper of the mixing granulator 52, thereby ensuring that the input load entering the mixing granulator 52 is slowed down and uniform); secondly, it is also to further mix the mixed materials already in the mixing bags 41 below each second silo 32, that is, to remix the discharge of the mixing bags 41 below each second silo 32, so as to achieve a better mixing effect. The present invention has a clever structure, strong applicability, good processing effect, and is suitable for the processing of single materials and mixed materials.

[0019] Furthermore, the first raw material crusher 21 is only provided with one discharge port, and the first silo 31 is only provided with one feed port and one discharge port, and the discharge port of the raw material crusher 21 is connected to the feed port of the first silo 31 .

[0020] Reference Figure 1 , single material processing only requires a set of corresponding devices from top to bottom, which is simple, convenient, practical and cost-controllable.

[0021] Furthermore, the second raw material crusher 22 is provided with multiple discharge ports, and the second silo 32 is provided with multiple feed ports, the number of the feed ports of the second silo 32 is equal to or less than the number of the discharge ports of the second raw material crusher 22, and each feed port of the second silo 32 is connected to the discharge port of the second raw material crusher 22.

[0022] Reference Figure 1 The mixing process is carried out by cooperating with multiple groups of corresponding devices from top to bottom, which is convenient and practical, cost-controlled, and has a good processing effect. Moreover, the feed port of the second silo 32 can be matched with a single or two discharge ports of the second raw material crusher 22 according to actual needs.

[0023] Furthermore, the lower tube wall of the mixing pipe 42 is an arc-shaped wall 42a, and the arc-shaped wall 42a has a downwardly convex arc. The two ends of the arc-shaped wall 42a extend from one end of the mixing pipe 42 to the other end. The bottom of the arc-shaped wall 42a is provided with a discharge port of the mixing pipe 42. The axial direction of the discharge port of the mixing pipe 42 is along the radial direction of the mixing pipe 42. The discharge port is connected to the feed port of the hopper of the mixing granulator 52. The upper tube wall of the mixing pipe 42 is provided with a feed port 42b which is connected to the multiple discharge ports of the mixing bag 41 below the second silo 32 in a one-to-one correspondence. Negative pressure prevention pipes 42c are provided at both ends of the mixing pipe 42. The outer ends of the negative pressure prevention pipes 42c are connected to the dust-proof pipe 42d, and the pipe mouth of the dust-proof pipe 42d is arranged downward.

[0024] Further preferably, the upper feed openings 42 b are symmetrically arranged on both sides of the outlet of the mixing pipe 42 , and the diameter of the upper feed openings 42 b gradually decreases from the end of the mixing pipe 42 toward the outlet of the mixing pipe 42 .

[0025] Still more preferably, an upper feed port 42b is provided directly above the discharge port of the mixing pipe 42, and the diameter of the upper feed port 42b is smaller than the diameters of the upper feed ports 42b on both sides thereof.

[0026] Reference Figure 1 , 2 The present invention adopts a horizontally placed mixing pipe 42 of a secondary mixing structure, an upper feed port 42b corresponding to the discharge port of the mixing bag 41 below the second silo 32 is arranged on the upper pipe wall of the mixing pipe 42, and the discharge port of the mixing pipe 42 is arranged on the lower pipe wall of the mixing pipe 42, and the lower pipe wall is arranged in an arc-shaped structure with a low middle and high sides, so that the mixed materials entering the mixing pipe 42 are evenly gathered to the discharge port of the mixing pipe 42 due to the effect of the arc-shaped structure, and the diameter of the upper feed port 42b gradually decreases from both sides to the middle, further ensuring that the feed of the mixing pipe 42 is evenly discharged from the discharge port of the mixing pipe 42, and due to the multiple mixing bags 41 The amount of material discharged from the discharge port is large and the concentration speed is fast, and negative pressure will appear in the mixing pipe 42, resulting in slow discharge of the material from the discharge port of the mixing bag 41 and slow discharge of the material from the mixing pipe 42 with a small amount, thereby affecting the production efficiency. The present invention provides negative pressure prevention pipes 42c at both ends of the mixing pipe 42. The negative pressure prevention pipe 42c is connected to the outside through a dustproof pipe 42d to avoid the aforementioned problem of negative pressure formation, and this negative pressure prevention pipe 42c is arranged at the highest position of the lower pipe wall, and there will be no leakage problem, and a dustproof pipe 42d with the pipe mouth facing downward is arranged at the outer end of the negative pressure prevention pipe 42c to prevent dust from falling from the outside or machine oil and water from falling or dripping into the mixing pipe 42.

[0027] Furthermore, the upper tube wall of the mixing pipe 42 is located at the avoidance position of the upper feed port 42b and is arranged with a plurality of negative pressure prevention ports 42e. The negative pressure prevention ports 42e are funnel-shaped with a large upper opening and a lower lower opening. The axial direction of the negative pressure prevention ports 42e is along the radial direction of the mixing pipe 42, and a dust prevention unit is provided on the negative pressure prevention ports 42e.

[0028] Furthermore, the dustproof unit is a dustproof cover arranged above the negative pressure prevention port 42e.

[0029] The double negative pressure prevention structure thus set further ensures the efficiency of feeding and discharging of the mixing pipe 42, mainly for the feeding of the mixing bag 41 under the second silo 32 with the largest amount, thereby ensuring the smooth and efficient operation of the equipment. The negative pressure prevention port 42e is formed into a funnel shape with a large upper opening and a low lower opening, and the air inlet and outlet directions of the pressure port on the upper pipe wall of the mixing pipe 42 are changed, and the air pressure is controlled to ensure the overall negative pressure prevention effect.
