Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, and in particular to a kind of forage feed deep processing equipment. Background Art

[0002] Forage feed is an important food resource in animal husbandry. Deep processing of feed is of great significance in feed production. In order to improve the storage performance, nutritional value and palatability of feed for livestock, feed is usually processed in a high-temperature and high-pressure supersaturated steam environment, and then the pressure is released instantly to discharge the nutrients that cannot be digested and released in the feed. At the same time, feed treated with high temperature and high pressure has better palatability, and feed storage performance is also better after high-temperature sterilization.

[0003] At present, a blasting container is mainly used to buffer and collect the instantly released high-temperature steam mixture of feed. However, the pressure released at the moment of blasting is relatively large. Although the blasting container is provided with a corresponding gas outlet, a large amount of feed will be entrained out of the gas outlet along with the gas, resulting in feed waste. If a filter is directly provided on the gas outlet, the high-speed flying feed will easily clog the filter on the one hand, and on the other hand, the impact on the filter will easily damage the filter. At the same time, after the blasting, it is difficult to collect the feed in the container. Summary of the invention

[0028] like Figure 1 As shown, combined Figure 2-4 The forage feed deep processing equipment of the present invention comprises:

[0029] The blasting chamber 1 is cylindrical, and has a cylindrical inner cavity 11 inside the blasting chamber 1. The axis of the cylindrical inner cavity 11 is arranged horizontally. A feed port 12, a discharge port 13 and an air outlet 14 are provided on the surface of the blasting chamber 1. The feed port 12 is interconnected with the middle of the cylindrical inner cavity 11. There are two air outlets 14. The two air outlets 14 are respectively interconnected with the side surfaces of both ends of the cylindrical inner cavity 11. A filter screen is arranged inside the air outlet 14. The discharge port 13 is interconnected with the side surfaces of one end of the cylindrical inner cavity 11. Preferably, the air outlet 14 is arranged vertically upward, and the discharge port 13 is arranged vertically downward;

[0030] The feeding dragon 2 is coaxially arranged in the cylindrical inner cavity 11, and the circumferential surface of the feeding dragon 2 is slidably matched with the inner wall of the cylindrical inner cavity 11, and the rotating shaft of the feeding dragon 2 passes through the blasting chamber 1 and protrudes from the outer surface of the blasting chamber 1;

[0031] The driving motor 4 is arranged outside the blasting chamber 1, and the driving end of the driving motor 4 is drivingly connected to the rotating shaft of the feeding dragon 2;

[0032] Preferably, the output end of the driving motor 4 is connected to the rotating shaft of the feeding dragon 2 through a transmission belt;

[0033] The filter screen is arranged inside the gas outlet 14 to filter the gas discharged from the cylindrical inner cavity 11 .

[0034] In the above embodiments, saturated water vapor containing feed from the autoclave enters the blasting chamber 1 from the feed port, and the gas is quickly discharged to the gas outlet 14 in the feeding spiral channel of the feeding dragon 2. However, due to its greater density, the feed cannot perform multiple lifting and lowering spiral movements in the spiral channel, and is eventually blocked by the feeding dragon 2 and settled in the cylindrical inner cavity 11. Some feed debris entrained in the high-pressure water vapor is blocked by the filter 3 in the process of being discharged from the gas outlet 14. After the steam explosion unloading is completed, almost all the feed is settled in the cylindrical inner cavity 11, and the driving motor 4 drives the feeding dragon 2 to rotate and drives the feed to be discharged from the discharge port 13, so that the deep-processed feed can be efficiently and centrally collected.

[0035] In the above embodiment, the feeding dragon 2 is arranged in the blasting chamber 1, which can not only be used to separate the feed and water vapor, but also can be directly used to transport the feed after the steam explosion, thereby solving the problem that the blasting chamber 1 cannot completely collect the water vapor entrained with the feed released by the steam explosion, and also solves the problem that the feed in the blasting chamber 1 is difficult to collect.

[0036] In some embodiments, a feed pipe 5 is also included, and the feed pipe 5 is connected to the feed port 12 , and one end of the feed pipe 5 close to the feed port 12 is expanded.

[0037] In the above embodiments, since the material from the autoclave mainly relies on instantaneous pressure changes during the steam explosion treatment, the high-pressure environment inside the feed is instantly released, thereby destroying the difficult-to-digest or difficult-to-destroy structure on the surface of the feed and releasing the internal nutrients. Therefore, in this process, the pressure release speed and the pressure difference before and after the release will directly affect the effect of the deep processing of the feed. In the above embodiments, the end of the feed pipe 5 is expanded to form a larger opening space at the end of the feed pipe 5. Compared with the feed pipe without expansion, the volume change of the material at the opening position is large, the pressure difference before and after is large, and the steam explosion effect is good. At the same time, the larger opening is conducive to preventing the feed from clogging the feed port 12.

[0038] In some embodiments, a plurality of cutting blades 6 are also included. The cutting blades 6 are disposed on the inner side of the feed tube 5 . The plurality of cutting blades 6 are arranged in a circular array along the axial direction of the feed tube 5 . The cutting edges of the cutting blades 6 face the incoming direction of the feed tube 5 .

[0039] In the above embodiments, the feed from the autoclave may be clumped at the moment of being discharged. Due to the clumping, the crushing and destruction effects of the feed inside the clumping and the feed on the surface at the moment of steam explosion are different, which ultimately affects the quality uniformity of the feed steam explosion treatment. In order to solve this problem, a cutting blade 6 is arranged in the feed pipe 5. The high-speed kinetic energy of the feed discharged instantly is combined with the cutting blade 6 to chop the clumped feed, so that the feed is looser and more uniform at the moment of discharge, and the steam explosion effect is better.

[0040] In some embodiments, a buffer tube 7, a piston 8 and a buffer spring 9 are also included, wherein the buffer tube 7 is communicated with the cylindrical inner cavity 11 inside the blasting chamber 1, a piston 8 is slidably arranged in the buffer tube 7, the piston 8 and the inner wall of the buffer tube 7 are slidably matched and fit closely with each other, the buffer spring 9 is arranged on the inner side of the end of the buffer tube 7 away from the blasting chamber 1, and the piston 8 selectively abuts against the surface of the buffer spring 9 during the movement of the buffer tube 7, and the expansion and contraction direction of the buffer spring is parallel to the conveying direction of the piston 8.

[0041] In the above embodiments, the internal volume of the blasting chamber 1 is fixed, and the spiral channel formed by the feeding dragon 2 and the cylindrical inner cavity 11 has a large resistance to the instantly released water vapor and feed. Therefore, the instantaneous pressure release effect of the high-pressure mixture released from the autoclave into the blasting chamber 1 will be suppressed, and the corresponding steam explosion deep processing effect of the feed will also be affected. In order to reduce this effect, the above embodiments adopt an additional connection buffer tube 7 to instantly release the volume in the blasting chamber 1. The specific method includes: the piston 8 is driven by the instantaneous release of the high-pressure mixed material, and will move rapidly in the direction away from the blasting chamber 1. At this time, the volume in the buffer tube 7 is connected with the blasting chamber 1, thereby increasing the volume of the blasting chamber and improving the blasting effect of the instantaneous pressure release of the feed. The buffer spring 9 is used to block and buffer the piston 8.

[0042] In the above embodiment, after the explosion chamber 1 is subjected to a steam explosion treatment, the piston 8 is reset manually to a state where the surface of the piston 8 is flush with the cylindrical inner cavity, so that the feed exploded into the buffer tube 7 can be pushed into the cylindrical inner cavity 11 for discharge processing.

[0043] In some embodiments, the side of the piston 8 close to the blasting chamber 1 has the same curvature as the cylindrical inner cavity 11. At the same time, in order to enable the piston 8 to maintain the surface curvature of the side close to the blasting chamber 1 corresponding to the inner surface curvature of the cylindrical inner cavity 11 during the reciprocating motion, a guide structure can also be provided in the buffer tube 7, such as a guide groove or a positioning guide rail, and the piston 8 is dynamically sealed with the guide structure.

[0044] In some embodiments, the piston 8 also includes a connecting rod 81, which is coaxially fixed on the side of the piston 8 away from the blasting chamber 1. The length of the connecting rod 81 is not shorter than the length of the buffer tube 7. A first limiting protrusion 71 is protruded from the middle part of the inner wall of the buffer tube 7, and a second limiting protrusion 811 is provided on the side of the connecting rod 81. When the side of the piston 8 close to the blasting chamber 1 is flush with the inner wall surface of the cylindrical inner cavity 11, the side of the second limiting protrusion 811 close to the blasting chamber 1 and the side of the first limiting protrusion 71 away from the blasting chamber 1 are abutted against each other. During the sliding process of the piston in the buffer tube 7, the second limiting protrusion selectively abuts against the buffer spring.

[0045] In the above embodiments, the connecting rod 81 is used to more conveniently adjust the position of the piston 8, for example, to perform a reset operation. The first limiting protrusion 71 cooperates with the second limiting protrusion 811 to quickly locate the reset position of the piston 8.

[0046] In some embodiments, a slider 82 is further included. The slider 82 is adjustably disposed on the inner side of one end of the buffer tube 7 away from the blasting chamber 1 , and the buffer spring 9 is fixedly disposed on a side of the slider 82 close to the blasting chamber 1 .

[0047] In the above embodiment, the installation position of the buffer spring 9 can be adjusted by the slider 82, thereby limiting the maximum stroke of the piston 8, and further limiting the maximum value of the internal space change of the blasting chamber 1 when performing steam explosion treatment. By adjusting the maximum value, it can adapt to different feed processing requirements.

[0048] In some embodiments, at least two oblong holes 72 are opened on the side surface of the end of the buffer tube 7 away from the blasting chamber 1 along the length direction of the buffer tube 7, and at least two limiting rods 821 are provided on the side surface of the slider 82. The positions of the limiting rods 821 and the oblong holes 72 correspond to each other. The limiting rods 821 pass through the oblong holes 72 and protrude from the outer surface of the buffer tube 7. A nut 83 is threadedly connected to each limiting rod 821, and the nut 83 selectively abuts against the outer surface of the buffer tube 7.

[0049] In the above embodiments, the distance between the nut 83 and the outer surface of the buffer tube 7 can be changed during the rotation of the nut 83 on the limiting rod 821. When the nut 83 is tightly pressed against the surface of the buffer tube 7, the position of the slider 82 relative to the buffer tube 7 is fixed. When the nut 83 is spaced apart from the buffer tube 7, the slider 82 can slide in the buffer tube 7, thereby changing the position of the slider 82.

[0050] In the above embodiments, the oblong hole 72 is preferably arranged at a side opening away from the blasting chamber 1. With this structure, the slider 82 can be disassembled and replaced.

[0051] The above adjustment method is simple. As a preferred embodiment, the two limit rods 821 are located on two opposite sides of the slider 82 .

[0052] In some embodiments, the axial direction of the buffer tube 7 and the axial direction of the feed port 12 are in the same radial plane of the cylindrical inner cavity 11 .

[0053] In the above embodiments, in order to allow the high-pressure material discharged from the feed port 12 to release the pressure quickly and avoid the material being affected by the resistance of the feeding dragon 2, the buffer tube 7 is arranged at a position close to the feed port 12. This can reduce the gas flow resistance between the feed port 12 and the inlet of the buffer tube 7, thereby increasing the speed of instantaneous pressure release of the feed explosion and the steam explosion effect.

[0054] In some embodiments, there may be multiple buffer tubes 7 , and the multiple buffer tubes 7 may be disposed at different positions of the blasting chamber 1 .

[0055] In some embodiments, an air outlet pipe 15 and a flange 18 are further included. The air outlet pipe 15 is communicated with the air outlet 14 . The flange 16 is coaxially arranged on the air outlet pipe 15 , and the filter screen 3 is clamped and arranged in the flange 16 .

[0056] In the above embodiments, the flange 18 is provided to enable the filter screen to be disassembled and replaced, thereby preventing the filter screen from being clogged with feed.

[0057] In some embodiments, there are two discharge ports 13 , and the two discharge ports 13 are respectively connected to the side surfaces at both ends of the cylindrical inner cavity 11 in the axial direction.

[0058] In the above embodiments, two discharge ports 13 are provided to enable discharge of materials in different directions of the blasting chamber 1 .

[0059] In some embodiments, as a preference, the spiral directions of the two ends of the feeding dragon 2 along the axial direction are opposite, and with the two discharge ports 13 , simultaneous discharge of materials from the discharge ports 13 at both ends can be achieved.

[0060] The steam explosion described in the above embodiments is steam explosion, which specifically refers to the operation of releasing the pressure of the feed instantly after being treated with water vapor at high temperature and high pressure.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
