Description

Technical Field

[0001] The invention belongs to the field of feed processing, and in particular relates to a secondary mixing mechanism of feed processing equipment. Background Art

[0002] Traditional feed processing is that each processing device (such as grinder, mixer, granulator) in the processing workshop is operated separately and in sections. The processing is not systematic, and transportation, integration and adjustment require a lot of time and labor costs. In particular, the processing of single materials and mixed materials in various ways, the processing effect and efficiency need to be improved.

[0003] For the aforementioned modified feed processing equipment, the feed mixing structure adopts the traditional mixing bag discharge bag outlet to discharge the feed directly into the mixing pelletizing machine hopper, which has the problems of too rapid discharge, large amount of feed and instability, and even causes the mixing pelletizing machine to have excessive feed load and too rapid feed, resulting in blockage, unstable operation and even shutdown. Summary of the invention

[0004] The purpose of the present invention is to provide a secondary mixing mechanism for feed processing equipment, which has an ingenious structure and can discharge mixed feed smoothly and evenly without leakage. It cooperates with the hopper of a mixing granulator of the feed processing equipment to improve the production efficiency of the entire feed processing equipment and is suitable for processing mixed feed.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is: a secondary mixing mechanism of a feed processing equipment, comprising a mixing pipe horizontally placed below a mixing bag below a second silo of the feed processing equipment, the lower pipe wall of the mixing pipe is an arc wall, the arc wall has a downward convex arc, the two ends of the arc wall are from one end of the mixing pipe to the other end, the bottom of the arc wall is provided with a discharge port of the mixing pipe, the axial direction of the discharge port of the mixing pipe is along the radial direction of the mixing pipe, and the mixing pipe The discharge port of the mixing pipe is connected with the feed port of the hopper of the mixing granulator of the feed processing equipment, the upper pipe wall of the mixing pipe is provided with the upper feed port which corresponds to the multiple discharge ports of the mixing bag below the second silo, and negative pressure-proof through pipes are provided at both ends of the mixing pipe, the outer ends of the negative pressure-proof through pipes are connected with the dust-proof pipe, and the pipe opening of the dust-proof pipe is arranged downward; the upper feed ports are symmetrically arranged on both sides of the discharge port of the mixing pipe, and the diameter of the upper feed port gradually decreases from the end of the mixing pipe to the discharge port of the mixing pipe.

[0006] Furthermore, an upper feed port is arranged directly above the discharge port of the mixing pipe, and the diameter of the upper feed port is smaller than the diameters of the upper feed ports on both sides thereof.

[0007] Furthermore, a plurality of negative pressure prevention openings are arranged at intervals on the upper tube wall of the mixing pipe at the avoidance position of the upper feed port. The negative pressure prevention openings are funnel-shaped with a large upper opening and a lower lower opening. The axial direction of the negative pressure prevention openings is along the radial direction of the mixing pipe, and a dust prevention unit is provided at the negative pressure prevention openings.

[0008] Furthermore, the dustproof unit is a dustproof cover arranged above the negative pressure prevention port.

[0009] Furthermore, a diamond mesh is provided at the pipe opening of the dust-proof pipe.

[0010] The technical effect of the present invention is that the two-stage mixing mechanism adopted by the present invention comprises a mixing pipe horizontally placed below the mixing bag below the second silo of the feed processing equipment, an upper feed port corresponding to the discharge port of the mixing bag below the second silo is arranged on the upper pipe wall of the mixing pipe, and the discharge port of the mixing pipe is arranged on the lower pipe wall of the mixing pipe, and the lower pipe wall is arranged in an arc structure with a low middle and high sides, so that the mixed materials entering the mixing pipe are evenly gathered to the discharge port of the mixing pipe due to the effect of the arc structure, and the diameter of the upper feed port gradually decreases from both sides to the middle, further ensuring that the feeding of the mixing pipe is evenly discharged from the mixing bag. The material is discharged from the discharge port of the pipe. Since the material discharge volume of the discharge ports of multiple mixing bags is large and the concentration speed is fast, negative pressure will appear in the mixing pipe, resulting in slow discharge of the material from the discharge port of the mixing bag and slow discharge of the mixing pipe with a small amount, thereby affecting the production efficiency. The present invention arranges anti-negative pressure pipes at both ends of the mixing pipe. The anti-negative pressure pipe is connected to the outside through a dust-proof pipe to avoid the aforementioned problem of negative pressure formation. The anti-negative pressure pipe is arranged at the highest position of the lower pipe wall, and the problem of leakage will not occur. A dust-proof pipe with the pipe mouth facing downward is arranged at the outer end of the anti-negative pressure pipe to prevent external dust or machine oil and water from falling or dripping into the mixing pipe.

[0015] 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.

[0016] Refer to the attached Figure 1 The present invention relates to a feed processing equipment, comprising 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 arranged in sequence 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 arranged in sequence. 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 discharge port of the second raw material crusher 21. The feed port of the first 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.

[0017] The mixing pipe 42 is a secondary mixing mechanism of the feed processing equipment of the present invention.

[0018] The feed processing equipment of the present invention has the multifunctional processing effects of crushing, mixing and granulating single materials and crushing, mixing and granulating mixed materials, and the mixing of mixed materials adopts the large mixing from the second silo 32 to the mixing bag 41 below it, and then the large mixed materials are remixed and collected by the mixing pipe 42 and then transferred to the mixing granulator 52. The use of such a two-stage mixing mechanism 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 hoppers below the second silo 32 are filled with the large mixed materials, the mixing granulator 52 will be filled with the large mixed materials. The discharge port of each mixing bag 41 directly discharges the material to the mixing granulator 52 hopper. 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 mixing granulator 52 hopper, 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] Reference Figure 1 Furthermore, the second raw material crusher 22 is provided with a plurality of discharge ports, and the second silo 32 is provided with a plurality of 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.

[0020] The mixing process is convenient and practical, with controllable costs and good processing effects, and 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.

[0021] Reference Figure 2 , the first embodiment of the present invention:

[0022] The lower tube wall of the mixing pipe 42 is an arcuate wall 42a, and the arcuate wall 42a has a downward convex arc shape. The two ends of the arcuate wall 42a extend from one end of the mixing pipe 42 to the other end. The bottom of the arcuate 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 of the mixing pipe (42) is connected to the feed port of the hopper of the mixing granulator 52 of the feed processing equipment. The upper tube wall of the mixing pipe 42 An upper feed port 42b is arranged to be connected to the multiple discharge ports of the mixing bag 41 below the second silo 32 in one-to-one correspondence, and negative pressure prevention pipes 42c are arranged at both ends of the mixing pipe 42. The outer end of the negative pressure prevention pipe 42c is connected to the dust-proof pipe 42d, and the pipe mouth of the dust-proof pipe 42d is arranged downward; the upper feed port 42b is symmetrically arranged on both sides of the discharge port of the mixing pipe 42, and the diameter of the upper feed port 42b gradually decreases from the end of the mixing pipe 42 to the discharge port of the mixing pipe 42.

[0023] Reference Figure 2 The embodiment of the present invention adopts a horizontally placed mixing pipe 42 of the secondary mixing mechanism, and 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 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 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 because a plurality of mixing bags 41 are arranged, the mixing pipe 42 is evenly discharged from the discharge port of the mixing pipe 42. 1 has a large amount of material discharged from the discharge port and a fast concentration speed, 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, and 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 a downward pipe opening 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.

[0024] 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.

[0025] Reference Figure 2 ,certainly Figure 3The corresponding structure is also given. In this way, the upper pipe wall of the entire mixing pipe 42 is arranged with an upper feed port 42b, and the diameter of the upper feed port 42b gradually decreases from both sides to the middle, so that the feed end of the entire mixing pipe 42 far away from the discharge port of the mixing pipe 42 has a large flow rate and a long path; the feed end close to the discharge port of the mixing pipe 42 has a small flow rate and a short path, so that the discharge to the discharge port of the mixing pipe 42 is uniform and stable.

[0026] Furthermore, a diamond mesh is provided at the mouth of the dustproof duct 42d. The diamond mesh does not affect the ventilation of the dustproof duct 42d, and can prevent foreign objects such as small animals from entering the dustproof duct 42d. Of course, when the dustproof duct 42d is actually designed, the smoothness design of the inner wall of the dustproof duct 42d is required to be high.

[0027] Reference Figure 3 , 4 , the second embodiment of the present invention:

[0028] 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.

[0029] Furthermore, the dustproof unit is a dustproof cover arranged above the negative pressure prevention port 42e.

[0030] 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.

[0031] Reference Figure 1 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.

[0032] Single material processing only requires one set of corresponding devices from top to bottom, which is simple, convenient, practical and cost-controllable.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
