Description

Technical Field

[0001] This invention belongs to the field of straw feed processing technology, specifically relating to an impurity screening device for straw fermented feed and its working method. Background Technology

[0002] Fermented straw becomes liquid feed. In a broad sense, liquid feed can include any form of liquid feed ingredient and product at room temperature, such as waste molasses, liquid oil, liquid methionine analogues, liquid milk replacers, and complete liquid feed for pigs. Typical liquid feed usually refers to a mixture of water and feed, or a mixture of liquid by-products from the food industry and conventional feed ingredients, with a dry matter content of 20%–30%. If water and feed are mixed in a ratio of 1.5:1 to 4:1 and fed immediately, or if the fermentation time is very short, it is called liquid feed or non-fermented liquid feed. However, for liquid feed (non-fermented liquid feed), it needs to be filtered before feeding to remove larger clumps or impurities, preventing animals from consuming large clumps that could impair digestion.

[0003] Therefore, it is necessary to design an impurity screening device for straw fermented feed and its working method to filter out impurities in liquid feed. Summary of the Invention

[0004] The purpose of this invention is to provide an impurity screening device for fermented straw feed and its working method.

[0005] To solve the above-mentioned technical problems, the present invention provides an impurity screening device for straw fermentation feed, comprising: a stirring shaft and two screening mechanisms symmetrically arranged on both sides of the stirring shaft, wherein the screening mechanism comprises: a box body, and the two sides of the box body are respectively provided with a plurality of filter holes and a plurality of feed inlets; wherein

[0006] The box body is provided with several guide plates on one side of the filter hole, and a baffle is provided on the side of the box body located at the feed inlet;

[0007] When the stirring shaft rotates forward, the guide plates are adapted to retract under force to block and clean the corresponding filter holes, and each guide plate is adapted to be stepped when blocking the filter holes to reduce resistance. Simultaneously, the guide plates are adapted to drive baffles to block each feed inlet when retracting; and

[0008] When the stirring shaft reverses, the guide plate resets to open the filter hole and the feed inlet, so that the box receives the fluid feed through the feed inlet and filters out impurities in the fluid feed through the filter hole.

[0009] Secondly, the present invention also provides a method for operating the impurity screening device for straw fermented feed as described above, comprising:

[0010] The stirring shaft drives the two screening mechanisms to rotate forward, causing each guide plate to retract and block the corresponding filter holes. Each guide plate is adapted to be stepped when blocking the filter holes to reduce resistance. Simultaneously, the guide plates are adapted to drive baffles to block each feed inlet during retraction.

[0011] The stirring shaft drives the two screening mechanisms to reverse, causing each guide plate to reset and open the filter holes and feed inlet. The box receives the liquid feed through the feed inlet and filters out the impurities in the liquid feed through the filter holes.

[0012] The beneficial effects of this invention are as follows: This straw fermentation feed impurity screening device is equipped with a box body. A stirring shaft drives the box body to rotate, achieving the stirring function. Simultaneously, a filter hole is opened on one side of the moving box body, and a feed inlet is opened on the other side, allowing the liquid feed to enter the box body. Impurities are filtered out through the filter hole, and the liquid feed flows out from the filter hole. Specifically, during the forward rotation of the box body driven by the stirring shaft, the guide plates located on the filter hole side will be resisted by the liquid feed and thus move backward, forming an inclined shape. This reduces the resistance during box rotation and facilitates the stirring of the liquid feed located below to the top. Furthermore, the guide plates... When retracting, the sealing element on the device blocks the filter holes to prevent liquid feed from entering the chamber through the filter holes. At the same time, the cleaning column at the front end of the sealing element extends into the filter holes to clean the inner wall of the filter holes. Also, when the guide plate retracts, it moves the baffle to block the feed inlet to prevent liquid feed from entering the chamber through the feed inlet. During the process of the stirring shaft driving the chamber to reverse, the guide plate is no longer under force and returns to its original position, thereby opening the filter holes and the feed inlet, allowing the liquid feed to enter the chamber through the feed inlet. Impurities are blocked inside the chamber by the filter holes. At this time, the outside of the chamber is filled with qualified liquid feed, thus achieving the filtration of impurities in the liquid feed.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides an impurity screening device for fermented straw feed, including: a stirring shaft 1 and two screening mechanisms 2 symmetrically arranged on both sides of the stirring shaft 1. The screening mechanism 2 includes: a box body 21, with a plurality of filter holes 211 and a plurality of feed inlets 212 respectively opened on both sides of the box body 21; wherein a plurality of guide plates 22 are arranged on one side of the box body 21 near the filter holes 211, and a baffle 23 is arranged on one side of the box body 21 near the feed inlets 212; when the stirring shaft 1 rotates forward, the guide plates 22 are adapted to bear force. The material guide plate 22 is retracted to block and clean the corresponding filter holes 211, and each of the guide plates 22 is adapted to be stepped when blocking the filter holes 211 to reduce resistance. At the same time, the guide plate 22 is adapted to drive the baffle 23 to block each feed inlet 212 when retracting. When the stirring shaft 1 reverses, the guide plate 22 resets to open the filter holes 211 and the feed inlets 212, so that the box 21 receives the liquid feed through the feed inlet 212 and filters out the impurities in the liquid feed through the filter holes 211 to prevent the impurities from affecting the subsequent use of the liquid feed.

[0027] In this embodiment, the fluid feed ground by the grinding device is thrown into the mixing tank. Mixing allows the fluid feed to be mixed more evenly. During the mixing process, to filter out impurities, this solution includes a housing 21. The mixing shaft 1 drives the housing 21 to rotate, achieving the mixing function. Simultaneously, a filter hole 211 is opened on one side of the moving housing 21, and a feed inlet 212 is opened on the other side, allowing the fluid feed to enter the housing 21 and filter out impurities through the filter hole 211. The fluid feed then flows out from the filter hole 211. Specifically, during the forward rotation of the housing 21 driven by the mixing shaft 1, the guide plates 22 located on the filter hole 211 side will be resisted by the fluid feed and will retract, forming an inclined shape. This reduces the resistance during the rotation of the housing 21 and facilitates the stirring of the fluid feed located at the bottom to the top. When the guide plate 22 retracts, it drives the sealing component 221 on it to block the filter hole 211, preventing the fluid feed from entering the box 21 through the filter hole 211. At the same time, the cleaning column 222 at the front end of the sealing component 221 extends into the filter hole 211 to clean the inner wall of the filter hole 211. When the guide plate 22 retracts, it drives the baffle 23 to block the feed inlet 212, preventing the fluid feed from entering the box 21 through the feed inlet 212. During the process of the stirring shaft 1 driving the box 21 to reverse, the guide plate 22 is not subjected to force and returns to its original position, thereby opening the filter hole 211 and the feed inlet 212, allowing the fluid feed to enter the box 21 through the feed inlet 212, and blocking impurities in the box 21 through the filter hole 211. At this time, the outside of the box 21 is all qualified fluid feed, thus achieving the filtration of impurities in the fluid feed.

[0030] like Figure 6 As shown, in this embodiment, each of the guide plates 22 is provided with a plurality of sealing members 221 on the side facing the box 21; the position of each sealing member 221 corresponds to each filter hole 211; the length of the sealing member 221 on each guide plate 22 increases sequentially from top to bottom, so that each guide plate 22 is in a stepped shape when blocking the filter hole 211.

[0031] In this embodiment, the length of the sealing member 221 increases sequentially from top to bottom to form a stepped inclined surface.

[0032] In this embodiment, the end of the sealing member 221 is provided with a cleaning column 222; the diameter of the sealing member 221 is larger than the diameter of the filter hole 211, and the diameter of the cleaning column 222 is smaller than the diameter of the filter hole 211; when the sealing member 221 blocks the filter hole 211, the cleaning column 222 extends into the filter hole 211 to clean the residue on its inner wall.

[0033] In this embodiment, when the filter hole 211 is reversed, qualified fluid feed will flow out, resulting in residue on the inner wall of the filter hole 211. The cleaning column 222 can be inserted into the filter hole 211 to clean the residue.

[0034] like Figure 7 As shown, in this embodiment, the inner wall of the housing 21 is provided with a transmission gear 213; one of the guide plates 22 meshes with the transmission gear 213 through a threaded post 223, and the transmission gear 213 meshes with one end of the baffle 23. That is, the guide plate 22 is adapted to drive the transmission gear 213 to rotate through the threaded post 223 when retracting, and the transmission gear 213 is adapted to drive the baffle 23 to move by rotating to close each feed port 212.

[0035] In this embodiment, specifically, a rack is provided at one end of the baffle 23. The rack meshes with the transmission gear 213. When the transmission gear 213 rotates, the rack will drive the baffle 23 to move up and down, thereby realizing the opening and closing of the feed port 212.

[0036] This embodiment also provides a working method for the straw fermentation feed impurity screening device as described above, which includes: driving the two screening mechanisms 2 to rotate forward by the stirring shaft 1, causing each guide plate 22 to retract to block the corresponding filter hole 211, and each guide plate 22 is adapted to be stepped when blocking the filter hole 211 to reduce resistance, and the guide plate 22 is adapted to drive the baffle 23 to block each feed inlet 212 when retracting; and driving the two screening mechanisms 2 to rotate in reverse by the stirring shaft 1, causing each guide plate 22 to reset to open the filter hole 211 and the feed inlet 212, the box 21 receiving the liquid feed through the feed inlet 212 and filtering out the impurities in the liquid feed through the filter hole 211.

[0037] In this embodiment, the two ends of the guide plate 22 are respectively connected to the box body 21 through the telescopic assembly 24; the telescopic assembly 24 includes: a mounting cylinder 241 and a telescopic column 242; wherein the mounting cylinder 241 is disposed on the box body 21, and the telescopic column 242 is disposed on the guide plate 22 and extends into the mounting cylinder 241; a return spring is disposed on the telescopic column 242, and the guide plate 22 is adapted to be driven by force to push the telescopic column 242 down to press the return spring.

[0038] In this embodiment, each of the guide plates 22 is provided with a plurality of sealing members 221 on the side facing the box 21; the position of each sealing member 221 corresponds to each filter hole 211; the length of the sealing members 221 on each guide plate 22 increases sequentially from top to bottom, so that each guide plate 22 is in a stepped shape when blocking the filter hole 211.

[0039] In this embodiment, the end of the sealing member 221 is provided with a cleaning column 222; the diameter of the sealing member 221 is larger than the diameter of the filter hole 211, and the diameter of the cleaning column 222 is smaller than the diameter of the filter hole 211; when the sealing member 221 blocks the filter hole 211, the cleaning column 222 extends into the filter hole 211 to clean the residue on its inner wall.

[0041] In summary, this straw fermentation feed impurity screening device, during the stirring process, incorporates a housing 21 to filter out impurities. The housing 21 is rotated by a stirring shaft 1 to achieve the stirring function. Simultaneously, a filter hole 211 is provided on one side of the housing 21 as it moves, and a feed inlet 212 is provided on the other side, allowing the liquid feed to enter the housing 21 and filter out impurities through the filter hole 211, while the liquid feed flows out through the filter hole 211. Specifically, during the forward rotation of the housing 21 by the stirring shaft 1, the guide plates 22 located on the side of the filter hole 211 will be resisted by the liquid feed and will retract, forming an inclined shape. This reduces the resistance during the rotation of the housing 21 and facilitates the stirring of the liquid feed at the bottom to the top. Furthermore, the guide plates 22, when retracting, will... The sealing component 221 on the device blocks the filter hole 211 to prevent the fluid feed from entering the box 21 through the filter hole 211. At the same time, the cleaning column 222 at the front end of the sealing component 221 extends into the filter hole 211 to clean the inner wall of the filter hole 211. When the guide plate 22 moves backward, it drives the baffle 23 to block the feed inlet 212 to prevent the fluid feed from entering the box 21 through the feed inlet 212. During the process of the stirring shaft 1 driving the box 21 to reverse, the guide plate 22 is not subjected to force and returns to its original position, thereby opening the filter hole 211 and the feed inlet 212, allowing the fluid feed to enter the box 21 through the feed inlet 212, and blocking impurities in the box 21 through the filter hole 211. At this time, the outside of the box 21 is all qualified fluid feed, thus achieving the filtration of impurities in the fluid feed.
