Technical Field

[0001] The invention relates to the technical field of straw biological pretreatment equipment, and in particular to a straw biological pretreatment mixer and a use method thereof. Background Art

[0002] With the advancement of science and technology and research, in the face of the difficult problem of straw treatment, biological enzymes can be used to degrade the straw's large molecular crude protein and fiber, catalytically decompose them into small molecules until they are degraded into amino acids and glucose, which are convenient for animals to directly absorb. The straw can be recycled for a second time to support the form of feed. Generally, the straw is broken up by a crusher and introduced into a mixing tank. Then a mixture of biological enzyme catalytic solution and water is introduced and stirred to facilitate mixing, decomposition and catalysis.

[0003] The existing pretreatment method breaks up the straw, introduces the broken straw into a mixing tank, and mixes it with a mixture of biological enzymes and aqueous solution. The crushing accuracy and mixing time of the entire treatment process directly affect the pretreatment effect, so the whole process takes a lot of time, affecting work efficiency and gradually increasing costs. Nowadays, it is particularly important to design a mixer with high crushing efficiency and high mixing efficiency. Summary of the invention

[0004] The invention discloses a straw biological pretreatment mixer and a use method thereof, aiming to solve the technical problem that the mixing efficiency of straw, biological enzyme and aqueous solution needs to be improved during the actual operation of the existing straw biological pretreatment mixer.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A straw biological pretreatment mixer comprises a reaction tank, a machine platform installed on one side of the top of the reaction tank, and a processing mechanism for cutting and grinding straw is arranged inside the machine platform; An auxiliary mechanism for facilitating straw feeding is arranged on the outside of the processing mechanism; The processing mechanism is also provided with a liquid adding mechanism for introducing biological enzymes and aqueous solutions; The processing mechanism cuts and grinds the straw, and the biological enzyme derived from the liquid adding mechanism is mixed with the crushed straw for pretreatment. Meanwhile, the intermittently operated auxiliary mechanism can assist the processing mechanism in feeding the slurry-like straw.

[0006] By arranging a processing mechanism inside the machine, the straw is processed by cutting and crushing, and the long-rod straw is processed into a powder. At the same time, the liquid adding mechanism adds the biological enzyme and the aqueous solution into the inside of the straw powder, so that the straw and the biological enzyme are pre-mixed. The additional auxiliary mechanism can intermittently expand the feeding section of the processing mechanism and change the direction of the liquid adding mechanism spraying the biological enzyme, so that the straw mixture is better lowered from the machine to the inside of the reaction tank, so that the straw can be pre-mixed for the second time, thereby greatly improving the pretreatment efficiency of traditional equipment for straw.

[0007] In a preferred embodiment, the processing mechanism includes a knife roller rotatably installed at one end of the machine platform, and a plurality of evenly distributed grinding discs are rotatably installed inside the machine platform, the top of each grinding disc passes through the interior of the machine platform, and the plurality of grinding discs are distributed in decreasing heights in the vertical direction, a first belt is transmission-sleeved on the outer side of the top of the plurality of grinding discs, a motor is distributed at one end of the first belt, the motor is vertically fixed on the top of the machine platform, and the output end of the motor is transmission-connected to the first belt, the auxiliary mechanism is sleeved on the outer side of the grinding disc, and the liquid adding mechanism is arranged on the top of the grinding disc.

[0008] By providing a knife roller and grinding disc structure driven by a motor, the knife roller is used to perform preliminary cutting of the straw, and the long rod-shaped straw is cut into segmented particles. Then, a large amount of granular straw is ground into powder at the same time with a number of grinding disc structures of different heights, thereby increasing the contact area between the straw and the biological enzyme, thereby greatly improving the pretreatment efficiency of the traditional equipment for the straw.

[0009] In a preferred embodiment, the auxiliary mechanism includes a top sleeve sleeved on the outer side of the top of each grinding disc, a bottom sleeve is distributed on the bottom of each top sleeve, and several bottom sleeves are connected to the interior of the reaction tank, and several evenly distributed folding leather sleeves are fixedly connected between the top sleeve and the bottom sleeve. A feeding port is vertically opened on the inner periphery of each bottom sleeve, and the tops of several top sleeves are commonly connected to a pressure rod, and an electric push rod is vertically fixed to the top of the machine, and the output end of the electric push rod vertically penetrates into the interior of the machine and is connected and fixed to the top of the pressure rod.

[0010] By arranging a structure consisting of a top sleeve and a bottom sleeve on the outer side of the grinding disc, and utilizing the extrusion relationship between the grinding disc and the bottom sleeve, granular straw can be ground into powder, and at the same time, the top sleeve is driven to move vertically by an electric push rod and a pressure rod, and the folding leather cover structure arranged between the top sleeve and the bottom sleeve is driven by extrusion, causing the folding leather cover to fold outward, thereby changing the size of the side of the feed port, so that the straw and the bio-enzyme mixture have more space to fall down, thereby ensuring the perfection and rationality of the cycle operation of this equipment.

[0011] In a preferred embodiment, the liquid adding mechanism includes a connecting groove vertically opened inside each of the grinding discs, a rubber ring is rotatably sleeved on the outer side of the top of the grinding disc, the rubber ring is through-connected to the inside of the connecting groove, a plurality of evenly distributed nozzles are fixedly installed on the outer side of the rubber ring, the nozzles are through-connected to the inside of the rubber ring, a pressure plate is slidably sleeved on the outer side of the top of each grinding disc, the pressure plate is in compression contact with the top of the nozzle, and each of the pressure plates is fixedly connected to the side of the pressure rod.

[0012] By providing a connecting groove structure that is connected to the inside of the grinding disc, while the grinding disc rotates, the rubber sleeve ring structure and the nozzle structure connected to the outside of the connecting groove are used to introduce the biological enzyme and the aqueous solution into the bottom of the grinding disc while the grinding disc rotates, so as to better mix them with the powdered straw, thereby improving the efficiency of straw pre-mixing. At the same time, the electric push rod drives the extrusion of the pressure plate, and the nozzle with a changed spray angle will directly face the discharge port structure inside the bottom sleeve, thereby improving the discharge efficiency of the straw mixture.

[0013] In a preferred solution, a plurality of evenly distributed spring connectors are vertically fixed between the top sleeve and the bottom sleeve, and the spring connectors and the folding leather case are interspersed and distributed.

[0014] By providing a spring structure connected between the top sleeve and the bottom sleeve, on the one hand, the spring can enhance the stability between the top sleeve and the bottom sleeve, and on the other hand, the resetting spring can drive the folding holster to reset and stretch, ensuring stability, thereby improving the perfection of the operation of the device.

[0015] In a preferred solution, an arc ring piece is sleeved and fixed on the top of the inner wall of each top sleeve, and an arc portion is arranged on the outer side of each grinding disc.

[0016] The arc ring part and the arc surface structure are provided to guide the straw falling into the sleeve, so that the straw can be better squeezed by the grinding disc, thereby ensuring the working stability of the grinding disc.

[0017] A method for using a straw biological pretreatment mixer comprises the following steps: S1: The user uses a transmission device to insert the whole straw from the side of the machine; S2: The processing mechanism will chop the straw inserted into the machine into long sections and grind it twice, turning the original whole straw into powder; S3: At the same time as step S2, the liquid adding mechanism sprays the biological enzyme and the aqueous solution on the grinding straw synchronously to pre-mix the straw and the biological enzyme; S4: At the same time as step S3, the auxiliary mechanism intermittently changes the diameter of the feeding end of the processing mechanism for the premixture, and at the same time drives the liquid adding mechanism to change the spraying direction of the biological enzyme and the aqueous solution, so as to better achieve the feeding of the premixture; S5: The premix removed from the inside of the machine will enter the reaction tank filled with biological enzymes and aqueous solution, so as to undergo a mixing reaction again until the reaction is completed and discharged from the inside of the reaction tank.

[0018] As can be seen from the above, the straw biological pretreatment mixer and the use method provided by the present invention have the following improvements and advantages compared with the prior art: First, by providing a knife roller and a grinding disc, the knife roller is used to perform preliminary cutting on the straw, and then a large amount of granular straw is ground at the same time with a number of grinding discs of different heights, and the straw is directly ground into powder, thereby increasing the contact area between the straw and the biological enzyme. A connecting groove structure is provided inside the grinding disc. When the grinding disc rotates, a rubber sleeve ring and a nozzle connected to the outside of the connecting groove are used to introduce the biological enzyme and the aqueous solution into the bottom of the grinding disc while the grinding disc rotates to produce the powdered straw, thereby better mixing the biological enzyme and the powdered straw, and greatly improving the efficiency of straw premixing.

[0019] Secondly, a structure consisting of a top sleeve, a bottom sleeve and a folding leather cover is arranged on the outer side of the grinding disc, and an electric push rod and a pressure rod are used to drive the top sleeve to move vertically, and the folding leather cover arranged between the top sleeve and the bottom sleeve is driven in an extrusion manner, so that the folding leather cover is folded outward, thereby changing the size of the side of the discharge port, so that the straw and biological enzyme mixture can have more space to fall down, and while the pressure rod moves, the synchronously driven pressure plate can change the spray angle of the nozzle, so that the biological enzyme is directly sprayed toward the discharge port structure arranged inside the bottom sleeve, thereby further improving the discharge efficiency of the straw mixture and ensuring the perfect and reasonable operation of the equipment.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The invention discloses a straw biological pretreatment mixer and a use method thereof, which are mainly applied to the scenario of straw biological pretreatment.

[0035] Reference Figures 1 to 12 A straw biological pretreatment mixer comprises a reaction tank 1, a machine platform 2 installed on one side of the top of the reaction tank 1, and a processing mechanism 3 for cutting and grinding straw is arranged inside the machine platform 2; An auxiliary mechanism 4 is provided on the outside of the processing mechanism 3 to facilitate the feeding of straw; The processing mechanism 3 is also provided with a liquid adding mechanism 5 for introducing biological enzymes and aqueous solutions; The processing mechanism 3 cuts and grinds the straw, and the biological enzyme extracted by the liquid adding mechanism 5 is mixed with the crushed straw for pretreatment. At the same time, the intermittently operated auxiliary mechanism 4 can assist the processing mechanism 3 in feeding the slurry-like straw.

[0036] In this embodiment: the user uses the transmission equipment to insert the whole straw from the side end of the machine 2, and starts the whole equipment at the same time. The processing mechanism 3 will chop and re-grind the straw inserted into the machine 2 into whole sections, and process the original whole straw into powder. At the same time, the liquid adding mechanism 5 will spray the grinding straw with biological enzymes and aqueous solutions to pre-mix the straw and the biological enzymes. At the same time, the auxiliary mechanism 4 intermittently changes the discharge end diameter of the premixture by the processing mechanism 3, and drives the liquid adding mechanism 5 to change the spraying direction of the biological enzymes and aqueous solutions, so as to better discharge the premixture. The premixture removed from the inside of the machine 2 will enter the reaction tank 1 filled with biological enzymes and aqueous solutions, so as to perform a mixing reaction again until the reaction is completed and discharged from the inside of the reaction tank 1.

[0037] In the above scheme, in order to allow the long-rod straw to better mix and react with the biological enzyme and the aqueous solution, the specific operation is as follows.

[0038] Reference Figures 1 to 7In a preferred embodiment, the processing mechanism 3 includes a knife roller 301 rotatably installed at one end of the machine table 2, and a plurality of evenly distributed grinding discs 302 are rotatably installed inside the machine table 2, and the top of each grinding disc 302 passes through the inside of the machine table 2, and the heights of the plurality of grinding discs 302 are successively decreased along the vertical direction, and a first belt 303 is transmission-sleeved on the outer side of the top of the plurality of grinding discs 302, and a motor 304 is distributed at one end of the first belt 303, the motor 304 is vertically fixed on the top of the machine table 2, and the output end of the motor 304 is transmission-connected to the first belt 303, the auxiliary mechanism 4 is sleeved on the outer side of the grinding disc 302, and the liquid adding mechanism 5 is arranged on the top of the grinding disc 302.

[0039] In this embodiment: the user uses the transmission equipment to insert the whole straw from the side end of the machine 2, and starts the motor 304 at the same time. The motor 304 rotates and drives all the grinding discs 302 to rotate synchronously through the first belt 303. The rotating grinding disc 302 will drive the knife roller 301 to rotate. The rotating knife roller 301 will perform preliminary cutting on the straw sent into the machine 2, while continuing to push the straw into the machine 2, while cutting the long rod-shaped straw into straw fragments. At the same time, the fragments of straw will be stacked on the top of each grinding disc 302 in turn as the number increases. The rotating grinding disc 302 will grind the fragments of straw, thereby performing secondary processing on the straw and grinding the fragments of straw into powder.

[0040] It should be additionally explained that a second belt 305 is connected between the knife roller 301 and a grinding disc 302 to drive the knife roller 301 to rotate.

[0041] In the above scheme, considering that as the powdered straw is stacked, in order to prevent a large amount of straw from causing blockage, thereby affecting the normal operation of the device, the specific operation is as follows.

[0042] Reference Figures 1 to 6 , Figures 8 to 10 In a preferred embodiment, the auxiliary mechanism 4 includes a top sleeve 401 which is sleeved on the outer side of the top of each grinding disc 302, and a bottom sleeve 402 is distributed at the bottom of each top sleeve 401, and several bottom sleeves 402 are connected to the interior of the reaction tank 1, and several evenly distributed folding leather sleeves 404 are fixedly connected between the top sleeve 401 and the bottom sleeve 402, and a discharge port 405 is vertically opened on the inner periphery of each bottom sleeve 402, and the tops of several top sleeves 401 are commonly connected to a pressure rod 406, and an electric push rod 407 is vertically fixed to the top of the machine 2, and the output end of the electric push rod 407 vertically penetrates into the interior of the machine 2 and is connected and fixed to the top of the pressure rod 406.

[0043] In this embodiment, when the grinding disc 302 rotates, the rotating grinding disc 302 and the bottom sleeve 402 generate extrusion friction, as well as extrusion shear force between the grinding discs 302, thereby grinding the broken pieces of straw into powder, and dropping them downward from the discharge port 405. As the grinding progresses, more and more powdered straw is located inside the bottom sleeve 402, and the discharge port 405 may be blocked. At this time, the electric push rod 407 starts to work, extends the output shaft outward, and drives the pressure rod 406 through the output shaft, causing the pressure rod 406 to squeeze and push the top The upper sleeve 401 causes the top sleeve 401 to move vertically and cooperate with the fixed bottom sleeve 402 to squeeze the folding leather cover 404 between the top sleeve 401 and the bottom sleeve 402, causing the folding leather cover 404 to fold outward, thereby providing more feeding space for the pulverized straw accumulated on the top of the feeding port 405, and the electric push rod 407 performs a reciprocating output end telescopic action, thereby driving the folding leather cover 404 to fold regularly outward, allowing the straw to better fall through the feeding port 405 and enter the interior of the reaction tank 1.

[0044] Among them, it should be additionally explained that: a number of evenly distributed spring connectors 403 are vertically fixed between the top sleeve 401 and the bottom sleeve 402, and the spring connectors 403 and the folding leather case 404 are interspersed. The spring connectors 403 provide a resetting force to drive the folding leather case 404 to stretch, while ensuring the stability of the folding leather case 404.

[0045] Further, it is supplemented that: the inner wall top of each top sleeve 401 is sleeved with an arc ring member 408, the outer side of each grinding disc 302 is provided with an arc portion 6, and the outer side of the grinding disc 302 is installed with a grinding member 7, such as Fig.11 and Fig.12 As shown, a lever 8 is installed on the top outer side of each grinding disc 302. Figure 2 As shown; the straw entering the top sleeve 401 will slide along the surface of the arc ring member 408 and the arc surface portion 6, so as to fall better to the grinding part of the grinding disc 302, and the additionally assembled grinding member 7 can cooperate with the rotation of the grinding disc 302 to better grind the straw particles. At the same time, the lever 8 that rotates with the grinding disc 302 will continuously move the straw particles accumulated on the top of the grinding disc 302, so that the straw is evenly distributed on the top of each grinding disc 302 to prevent blockage.

[0046] Specifically, the grinding piece 7 is in a triangular shape, which facilitates the material to fall downward to between the grinding piece 7 and the grinding disc 302 for grinding.

[0047] In the above scheme, in order to allow straw and biological enzymes to have better contact space, the specific operations are as follows.

[0048] Reference Figures 1 to 7 , Fig.10 In a preferred embodiment, the liquid adding mechanism 5 includes a connecting groove 501 vertically opened inside each grinding disc 302, and a rubber ring 502 is rotatably sleeved on the outer side of the top of the grinding disc 302. The rubber ring 502 is connected to the inside of the connecting groove 501 through a through connection, and a plurality of evenly distributed nozzles 503 are fixedly installed on the outer side of the rubber ring 502, and the nozzles 503 are connected to the inside of the rubber ring 502 through a through connection. A pressure plate 505 is slidably sleeved on the outer side of the top of each grinding disc 302, and the pressure plate 505 is pressed and contacted with the top of the nozzle 503, and each pressure plate 505 is fixedly connected to the side of the pressure rod 406.

[0049] In this embodiment: the user can introduce the biological enzyme and the aqueous solution into the interior of the connecting groove 501 through an external device, and the biological enzyme and the aqueous solution located inside the connecting groove 501 will be sprayed out through the rubber ring 502 and the nozzle 503, and sprayed to the top of the grinding disc 302, so as to be evenly mixed with the powdered straw; under normal circumstances, the injection port of the nozzle 503 is directed toward the grinding disc 302, and when the electric push rod 407 pushes the pressure rod 406, the moving pressure rod 406 will synchronously drive the pressure plate 505, causing the pressure plate 505 to move synchronously, and while moving, it will squeeze the top of the nozzle 503, thereby causing the nozzle 503 to rotate slightly, and the injection port of the nozzle 503 is changed to face the discharge port 405, thereby exerting a downward external force on the accumulated straw, so that the accumulated powdered straw and the biological enzyme mixture can be better discharged through the discharge port 405.

[0050] It should be noted that the rubber sleeve ring 502 is soft and can be slightly deformed. The heights of the plurality of pressure plates 505 decrease in sequence and match the heights of the nozzles 503 distributed on the top of each grinding disc 302 .

[0051] Furthermore, the tops of several grinding discs 302 rotate together and are connected to the same liquid guide tube 504. The liquid guide tube 504 is distributed on the top of the machine 2, and each connecting groove 501 is connected to the inside of the liquid guide tube 504. The liquid guide tube 504 is connected to an external liquid preparation device, and the biological enzyme and aqueous solution are introduced into the inside of the connecting groove 501 through the liquid guide tube 504. The top sleeve 401 is distributed in a stepped manner, so that the material can fall to the lower grinding disc 302, and the straw material can also be moved during the rotation of the nozzle 503 to further prevent blockage and improve the uniformity of the distribution of the straw material. At the same time, it can also push the broken straw accumulated on the top of each grinding disc 302, so that the straw is evenly distributed on the top of each grinding disc 302.

[0052] Working principle: When in use, the user uses the transmission equipment to insert the whole straw from the side end of the machine 2, and starts the motor 304 at the same time. The motor 304 rotates and drives all the grinding discs 302 to rotate synchronously through the first belt 303. The rotating grinding disc 302 will drive the knife roller 301 to rotate. The rotating knife roller 301 will perform preliminary cutting on the straw sent into the machine 2, while continuing to push the straw into the machine 2, while cutting the long rod-shaped straw into pieces of straw. At the same time, the pieces of straw will be stacked on the top of each grinding disc 302 in turn as the number increases. The rotating grinding disc 302 The broken pieces of straw will be ground again, so as to perform secondary processing on the straw, and the broken pieces of straw will be ground into powder. At the same time, the user introduces the biological enzyme and the aqueous solution into the interior of the connecting groove 501 through an external device. The biological enzyme and the aqueous solution in the connecting groove 501 will be sprayed out through the rubber sleeve ring 502 and the nozzle 503, and sprayed to the top of the grinding disc 302, so as to be evenly mixed with the powdered straw. As time goes by, the powdered straw in the bottom sleeve 402 becomes more and more. At this time, the electric push rod 407 starts to work, extends the output shaft outward, and drives the pressure rod 406 through the output shaft, so that the pressure rod 4 06 squeezes and pushes the top sleeve 401, causing the top sleeve 401 to move vertically and cooperate with the fixed bottom sleeve 402, squeezing the folding leather cover 404 between the top sleeve 401 and the bottom sleeve 402, so that the folding leather cover 404 is folded outward, thereby providing more feeding space for the shredded straw accumulated on the top of the feeding port 405, and the electric push rod 407 performs a reciprocating output end telescopic action, thereby driving the folding leather cover 404 to fold regularly outward, shaking to allow the straw to better fall through the feeding port 405 and enter the interior of the reaction tank 1, and the electric push rod 407 pushes the pressure rod At the same time as the folding holster 404 is folded, the accumulated straw powder and the bio-enzyme mixture can be better discharged through the discharge port 405, and the premix removed from the inside of the machine 2 will enter the reaction tank 1 filled with the bio-enzyme and the aqueous solution, so as to perform a mixing reaction again until the reaction is completed and discharged from the inside of the reaction tank 1.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
