Description

Technical Field

[0001] The utility model relates to the technical field of feed detoxification, in particular to a feed heavy metal detoxification and purification device based on biochar. Background Technique

[0002] The feed based on biochar is also called carbon-based feed. Carbon-based feed is mainly divided into various types such as carbon-based compound feed, carbon-based premix, and carbon-based feed additive. These types are formulated according to different needs of animals and breeding environments to meet the growth and health needs of animals. However, biochar is a kind of porous solid granular material generated by high-temperature pyrolysis of carbon-rich biomass under anaerobic or anoxic conditions. These biomass raw materials, such as crop straws, woods, fruit shells and other raw materials, may be mildewed, etc., and carry bacteria and viruses inside them. When doped in the feed, it needs to be detoxified and purified to avoid affecting the growth of animals in the later stage.

[0003] At present, the methods for detoxifying feed include chemical detoxification and physical detoxification. Although the chemical detoxification effect is good, it may damage the nutrients in the feed. The physical detoxification effect is worse than that of chemical detoxification, but it has less destructive effect on the nutrients in the feed. If only chemical or physical detoxification is used alone, it may have a good removal effect on specific types of toxins, but for complex feed pollution situations, it is often difficult to comprehensively deal with, and the detoxification effect is relatively poor. Based on the above situation, it is necessary to design a feed heavy metal detoxification and purification device based on biochar to solve the above problems. Content of the Utility Model

[0004] The utility model provides a feed heavy metal detoxification and purification device based on biochar to solve the problems of single detoxification method and poor detoxification effect in the prior art.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] Reference Figures 1 - 4 As shown, a biochar-based feed heavy metal detoxification and purification device includes a processing unit 1, which includes a cooking chamber 2 and a mixing chamber 3. A pipe 4 for outputting high-temperature cooking steam to the cooking chamber 2 is provided inside the cooking chamber 2, and the input end of the steam pipe 4 can be connected to an external steam delivery pipeline. A breathable metal mesh 21 for supporting feed is provided inside the cooking chamber 2, and a vibration component is provided inside the cooking chamber 2. The vibration component is used to vibrate the breathable metal mesh 21 to achieve comprehensive cooking of the feed with high-temperature steam. When in use, first The feed that needs to be detoxified is spread flat on the breathable metal mesh 21, and then steam is output from the bottom of the breathable metal mesh 21 through the steam pipe 4 to perform high-temperature cooking on it, thereby destroying harmful substances in the feed, such as mycotoxins, bacteria, etc., and reducing their biological activity. During the cooking process, the breathable metal mesh 21 is vibrated from time to time by the vibration component, so that the feed above is continuously vibrated to promote the increase of the gap between the feed particles, thereby improving the ventilation efficiency of the breathable metal mesh 21, allowing the high-temperature steam to be more comprehensively and evenly dispersed into the feed, and making the cooking and disinfection more uniform.

[0024] At the same time, in order to purify the residual pathogens and the like in the feed after cooking and disinfection, the cooked feed enters the mixing chamber 3 for further processing. A spray pipe 5 for adding enzyme preparations to the feed in the mixing chamber 3 is also provided inside the mixing chamber 3. The spray pipe 5 can be connected to an external pipeline and transported through a pump body or the like to deliver enzyme preparations or microorganisms. The microorganisms or enzyme preparations can further decompose and transform the toxins remaining in the feed after high-temperature cooking, thereby improving the detoxification efficiency. In addition, since high-temperature cooking may cause the nutrients in the feed to be destroyed or lost, the addition of microorganisms or enzyme preparations can decompose complex components, such as amylase, protease, cellulase, etc., and release nutrients that are more easily absorbed, thereby compensating for the nutritional loss to a certain extent. In addition, in order to improve the contact uniformity between the enzyme preparation and the feed, a mixing component is also provided inside the mixing chamber 3 to fully mix the enzyme preparation and the feed.

[0025] Reference Figure 4 As shown, further, the vibration component includes a rotating shaft 6 rotatably connected to the cooking chamber 2 and at least two elliptical knocking wheels 61 provided on the rotating shaft 6. The processing part 1 is provided with a first motor 62 whose output end is connected to one end of the rotating shaft 6. When the knocking wheel 61 rotates following the rotating shaft 6, the breathable metal mesh 21 can be intermittently knocked at the bottom of the breathable metal mesh 21. The rotating shaft 6 is driven by the first motor 62 to drive the knocking wheel 61 to rotate, so that the knocking wheel 61 continuously shakes the breathable metal steel at the bottom, so that the feed above the breathable metal mesh 21 vibrates during cooking, making it easier for steam to enter the gaps between the feed, thereby improving the uniformity of cooking.

[0026] Reference Figure 2 As shown, further, the mixing component includes a partition tube 7 coaxially arranged with the mixing bin 3 and a spiral conveying blade 71 located inside the partition tube 7, both ends of the partition tube 7 are open and there is a certain gap between the inner wall of the mixing bin 3, and the partition tube 7 is connected to the inside of the mixing bin 3 through a connecting rod, and a second motor 72 is provided at the upper end of the mixing bin 3, and the output shaft of the second motor 72 is connected to the spiral conveying blade 71, and the second motor 72 drives the spiral conveying blade 71 to rotate, and the feed at the bottom of the mixing bin 3 is continuously flipped upward by the spiral conveying blade 71, and falls from the upper end of the partition tube 7 and the inner wall of the mixing bin 3 to the bottom of the mixing bin 3, and the feed is continuously stirred in this cycle, so that the enzyme preparation sprayed by the upper spray pipe 5 can be better mixed with the feed. After the mixing is completed, the discharge port at the bottom of the mixing bin 3 is opened to discharge the feed.

[0027] Among them, reference Figure 3As shown, the interior of the cooking bin 2 is slidably connected to a receiving plate 8 located below the metal filter screen, and one end of the receiving plate 8 extends to the outside of the cooking bin 2. When the breathable metal mesh 21 vibrates, some feed may fall from the mesh holes of the breathable metal mesh 21. At this time, the receiving plate 8 can be used for unified collection, and the receiving plate 8 can be regularly pulled out of the cooking bin 2 for unified processing.

[0028] Further, refer to Figure 3 As shown, a sealing cover 11 is slidably connected to the top of the processing part 1. When cooking, the sealing cover 11 is slid to the top of the breathable metal mesh 21 to seal the cooking bin 2 to reduce steam leakage and improve the cooking effect. After the cooking is completed, the sealing cover 11 is slid to one side, which makes it easier to transport the feed to the mixing bin 3.

[0029] Among them, a telescopic part 9 is provided on one side of the processing part 1. The telescopic part 9 can be an electric telescopic rod or other device. A push plate 91 is connected to the movable end of the telescopic part 9. The telescopic part 9 drives the movement of the push plate 91 to push the feed on the metal filter screen into the mixing bin 3, which is more convenient.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
