Description

Technical Field

[0001] The invention belongs to the field of feed processing, in particular to a pressure-bearing biomass feed puffing reactor. Background Art

[0002] Biomass feed refers to feed made from biomass as raw material and processed through a specific process. Biomass feed is not only environmentally friendly and sustainable, but also nutritious and easy to digest and absorb, which has a positive impact on the growth and health of livestock. During the preparation process, biomass feed can be improved in taste and digestibility and nutritional value after being puffed. The pressurized biomass feed puffing reactor is a closed container that can withstand a certain pressure and is used to complete the puffing reaction process of biomass feed. The raw materials are puffed through heating, pressurization, stirring and other process conditions. In addition, the reactor body and related components can withstand the working pressure under high temperature and high pressure environment to ensure that the equipment will not leak or rupture during the process of puffing biomass feed.

[0003] The patent with announcement number CN209807111U discloses a reactor for feed processing. In view of the problem that some traditional reactors for processing feed have slow heating speed and slow discharging speed, resulting in low feed processing efficiency, the following scheme is proposed, which includes a box body fixed on a support seat, the inner side wall of the box body is fixed with a mounting cover along the circumferential direction, and a plurality of heat-conducting needles are arranged on the mounting cover, and the outer side wall of the box body is provided with an opening facing the mounting cover, and the opening is connected to the inside of the mounting cover. The patent sets two discharging pipes, both of which can be used for discharging, so that the discharging speed is fast, and the discharging time is reduced to a certain extent, thereby improving the processing efficiency, and the heat-conducting needles have good thermal conductivity, so that the heat transfer efficiency is high, and then the material is heated up quickly, thereby improving the fermentation efficiency of the material.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The feed raw materials are added to the kettle body through a feeding pipe for reaction. When adding materials in this way, the feed raw materials are only concentrated on the same side of the kettle body. When the stirring device stirs the feed raw materials, it is difficult to fully contact with the accumulated raw materials, resulting in too long stirring time, which in turn affects the puffing reaction efficiency.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The pressurized biomass feed puffing reactor described in the present invention utilizes a circulating scattering mechanism. When raw materials are added to the reactor body through a feeding pipe, they will be scattered by a plurality of rotating paddles and scattered inside the reactor body, so that the raw materials are evenly distributed inside the reactor body.

Moreover, when no more raw materials are added to the feeding pipe, a plurality of paddles are driven to retract into the rotating cylinder at the same time, and the raw materials stuck in the gap between adjacent paddles lose support and fall off, thereby avoiding the situation that the raw materials are stuck in the gap between adjacent paddles, affecting the addition amount of the raw materials and the use effect of the subsequent paddles. Moreover, when the raw materials are passed through the adjacent paddles, the raw materials are evenly distributed inside the reactor body. When it falls from the gap between the plates, it will fall into the collecting hopper and move along the inclined surface of the bottom of the collecting hopper to the middle position of the bottom of the collecting hopper, and then drive the collecting hopper to slide upward with the sliding rod until the bottom of the fixed cylinder fits with the bottom of the inner cavity of the collecting hopper. At this time, the raw materials at the bottom of the inner cavity of the collecting hopper will be covered by the fixed cylinder, and then the auger blades will be driven to rotate to move the raw materials upward until the raw materials are discharged from the discharge pipe. At this time, the paddle continues to rotate, which will break up the falling raw materials and scatter them into the kettle body, thereby avoiding the situation where the raw materials at the gap between the paddles fall and fall to the same position inside the kettle body, resulting in uneven distribution of the raw materials inside the kettle body, which affects the stirring effect, and further improves the puffing reaction efficiency.

[0021] 2. The pressurized biomass feed puffing reactor described in the present invention utilizes a motor 5 to drive the stirring shaft to rotate, and utilizes the rotation of the stirring rod to stir and mix the raw materials. At the same time, since the scraper is in contact with the inner wall of the reactor body, the raw materials adhered to the inside of the reactor body will be scraped off, thereby avoiding the situation where the raw materials adhere to the inner wall of the reactor body and thus affect the stirring effect.

[0038] A gear ring 1 29 is fixedly connected to the upper end of the rotating cylinder 14, and a gear 28 is rotatably provided on one side of the fixed ring 17. The gear 28 is meshed with the tooth blocks on the outer ring of the gear ring 1 29. A motor 3 21 is fixedly connected to one side of the fixed ring 17, and the output end of the motor 3 21 is fixedly connected to the gear 2 28.

[0039] A sliding rod 20 is fixedly connected to one side of the lower end of the lifting rod 13, and the sliding rod 20 is slidably connected to the collecting hopper 16. A threaded rod 19 is rotatably provided on one side of the lower end of the lifting rod 13, and the threaded rod 19 is threadedly connected to one side of the collecting hopper 16. A motor 2 18 is fixedly connected to one side of the lower end of the lifting rod 13, and the output end of the motor 2 18 is fixedly connected to one end of the threaded rod 19.

[0040] A fixed cylinder 23 is fixedly connected to the middle of the lifting rod 13, and the fixed cylinder 23 penetrates the middle of the rotating cylinder 14 and is rotatably connected. A rotating shaft 24 is rotatably provided on the upper end of the inner cavity wall of the fixed cylinder 23, and an auger blade 25 is sleeved and fixedly connected to the rotating shaft 24.

[0041] The upper end surface of the fixed cylinder 23 is fixedly connected to the motor 4 22, and the output end of the motor 4 22 is fixedly connected to the upper end of the rotating shaft 24.

[0042] A discharge pipe 26 is provided on the left side of the upper end of the fixed cylinder 23 .

[0043] Specifically, when the existing reactor is in use, the feed raw materials are added into the reactor body 1 through the feeding pipe for reaction. When the feed raw materials are added in this way, the feed raw materials are only concentrated on the same side of the reactor body 1. When the stirring device stirs the feed raw materials, it is difficult to fully contact with the accumulated raw materials, resulting in a long stirring time, which further affects the puffing reaction efficiency.

[0044] Therefore, in order to solve the above problems, when the present embodiment is used, the kettle cover 3 is opened, the motor 10 is used to drive the gear 11 to rotate, so that the rack rod 12 is lowered, and the rotating cylinder 14 is extended into the kettle body 1 until the rotating cylinder 14 is lower than the discharge end of the feeding tube 2, and then the raw materials are added through the feeding tube 2. At the same time, the motor 3 21 is used to drive the gear 2 28 to rotate, so that the gear ring 1 29 and the rotating cylinder 14 can rotate at the same time. When the rotating cylinder 14 rotates, the multiple paddles 15 will also rotate. When the raw materials fall through the feeding tube 2, they will be scattered by the paddles 15 and thrown into the kettle body 1, so that the raw materials are evenly distributed in the kettle body 1. When the stirring rod 9 rotates, it can be in uniform contact with the raw materials, thereby reducing the subsequent stirring time and improving the puffing reaction efficiency.

[0045] In order to improve the continuous breaking effect of the raw materials, a plurality of paddles 15 are provided, and the plurality of paddles 15 are cyclically and alternately used to break up the raw materials. Moreover, since the gaps between the plurality of paddles 15 are small and some raw materials may have a certain viscosity, when the raw materials are impacted, some raw materials may be squeezed and stuck in the gaps between adjacent paddles 15, thereby affecting the amount of raw materials added and the effect of subsequent use of the paddles 15. Therefore, in order to avoid this situation, when no more raw materials are added to the feeding pipe 2, the motor 6 33 is used to drive the gear 3 34 to rotate, so that the gear ring 2 31 and the rotating ring 3 0 rotates simultaneously. When the multiple connecting rods 32 rotate simultaneously, the multiple paddles 15 will slide on the rotating cylinder 14 simultaneously until the ends of the paddles 15 are retracted into the rotating cylinder 14. Moreover, when the paddles 15 are retracted into the rotating cylinder 14, they will not be completely separated from the rotating cylinder 14. The ends of the paddles 15 will only be embedded into the edge of the rotating cylinder 14. When all the paddles 15 are retracted into the rotating cylinder 14, the raw materials stuck in the gaps between the adjacent paddles 15 will fall off, thereby avoiding the situation that the raw materials are stuck in the gaps between the adjacent paddles 15, thereby affecting the amount of raw materials added and the subsequent use effect of the paddles 15;

[0046] However, when the raw materials at the gaps between the paddles 15 fall, they will still fall to the same position inside the kettle body 1, causing the raw materials to be unevenly distributed inside the kettle body 1, thereby affecting the stirring effect. Therefore, in order to avoid this problem, when the raw materials fall through the gaps between the adjacent paddles 15, they will fall into the collecting hopper 16 and move along the inclined surface at the bottom of the collecting hopper 16 to the middle position of the bottom of the collecting hopper 16, and then the motor 18 drives the threaded rod 19 to rotate, so that the collecting hopper 16 slides upward along the sliding rod 20 until the bottom of the fixed cylinder 23 is aligned with the collecting hopper 16. The bottom of the inner cavity of the hopper 16 is fitted, and at this time, the raw materials at the bottom of the inner cavity of the collecting hopper 16 will be covered by the fixed cylinder 23, and then the motor 22 is used to drive the auger blade 25 to rotate, so that the raw materials can be moved upward until the raw materials are discharged from the discharge pipe 26. At this time, the paddle 15 continues to rotate, and the falling raw materials will be scattered and thrown into the kettle body 1, thereby avoiding the situation that when the raw materials at the gap of the paddle 15 fall, the raw materials fall to the same position inside the kettle body 1, which affects the stirring effect, and further improves the puffing reaction efficiency;

[0047] After the raw materials are evenly distributed inside the kettle body 1, the rotating cylinder 14 is driven to move out of the kettle body 1, and then the kettle cover 3 is closed, and the liquid catalyst is added to the kettle body 1 through the liquid adding pipe 4, and then the stirring shaft 8 is driven to rotate, and the stirring rod 9 is used to stir and mix the raw materials. At the same time, the electric heating tube 35 can be used to heat the inside of the kettle body 1 to provide temperature conditions for the reaction. At the same time, the inert gas required for the reaction inside the kettle body 1 is used to be fed into the pressure port 36, and the pressure inside the kettle body 1 is detected in real time. By increasing the pressure inside the kettle body 1, the rapid evaporation of moisture and other volatile components in the biomass raw materials is promoted, thereby facilitating the expansion of the biomass raw materials;

[0048] After the reaction is finished, open the valve at the discharge port 6 to discharge the raw materials from the kettle body 1.

[0049] In this embodiment, Figure 2 and Figure 8 As shown, a motor 5 27 is fixedly connected to the middle of the lower end surface of the kettle body 1, and the output end of the motor 5 27 is fixedly connected to the bottom of the stirring shaft 8. A scraper 7 is fixedly connected to one end of the stirring rod 9, and the scraper 7 is in contact with the inner wall of the kettle body 1.

[0050] Specifically, the motor 5 27 can be used to drive the stirring shaft 8 to rotate, and the stirring rod 9 can be used to rotate to stir and mix the raw materials. At the same time, since the scraper 7 is in contact with the inner wall of the kettle body 1, the raw materials adhering to the inside of the kettle body 1 will be scraped off, thereby avoiding the situation where the raw materials adhere to the inner wall of the kettle body 1 and thus affect the stirring effect.

[0051] Working principle: open the kettle cover 3, use the motor 10 to drive the gear 11 to rotate, so that the rack rod 12 descends, and the rotating cylinder 14 extends into the kettle body 1 until the rotating cylinder 14 is lower than the discharge end of the feeding tube 2, and then the raw materials are added through the feeding tube 2. At the same time, the motor 3 21 drives the gear 2 28 to rotate, so that the gear ring 1 29 and the rotating cylinder 14 can rotate at the same time. When the rotating cylinder 14 rotates, multiple paddles 15 will also rotate. When the raw materials fall through the feeding tube 2, they will be scattered by the paddles 15 and thrown into the kettle body 1, so that the raw materials are evenly distributed in the kettle body 1. When the stirring rod 9 rotates, it can be evenly contacted with the raw materials, thereby reducing the subsequent stirring time and improving the puffing reaction efficiency; and in order to improve the continuous stirring of the raw materials In order to achieve a dispersing effect, a plurality of paddles 15 are provided, and the plurality of paddles 15 are cyclically and alternately used to disperse the raw materials. Moreover, since the gaps between the plurality of paddles 15 are small and some of the raw materials may have a certain viscosity, when the raw materials are impacted, some of the raw materials may be squeezed and stuck in the gaps between adjacent paddles 15, thereby affecting the amount of raw materials added and the subsequent use effect of the paddles 15. Therefore, in order to avoid this situation, when no more raw materials are added to the feeding tube 2, the motor 6 33 is used to drive the gear 3 34 to rotate, so that the gear ring 2 31 and the rotating ring 30 rotate at the same time. When the plurality of connecting rods 32 rotate at the same time, the plurality of paddles 15 will slide on the rotating cylinder 14 at the same time until the end of the paddle 15 is retracted into the rotating cylinder 14, and the paddle 15 When the paddles 15 are retracted into the rotating cylinder 14, they will not be completely separated from the rotating cylinder 14, and their ends will only be embedded in the edge of the rotating cylinder 14. When all the paddles 15 are retracted into the rotating cylinder 14, the raw materials stuck in the gaps between adjacent paddles 15 will fall off, thereby avoiding the situation where the raw materials are stuck in the gaps between adjacent paddles 15, thereby affecting the amount of raw materials added and the subsequent use effect of the paddles 15; and since the raw materials in the gaps between the paddles 15 will fall off and still fall to the same position inside the kettle body 1, the raw materials will be unevenly distributed inside the kettle body 1, thereby affecting the stirring effect. Therefore, in order to avoid this problem, when the raw materials fall off through the gaps between adjacent paddles 15, they will fall into the collecting hopper 16 and be mixed with the raw materials at the bottom of the collecting hopper 16. The inclined plane moves to the middle position of the bottom of the collecting hopper 16, and then the motor 2 18 is used to drive the threaded rod 19 to rotate, so that the collecting hopper 16 slides upward along with the sliding rod 20 until the bottom of the fixed cylinder 23 fits with the bottom of the inner cavity of the collecting hopper 16. At this time, the raw materials at the bottom of the inner cavity of the collecting hopper 16 will be covered by the fixed cylinder 23, and then the motor 4 22 is used to drive the auger blade 25 to rotate, so that the raw materials can be moved upward until the raw materials are discharged from the discharge pipe 26. At this time, the paddle 15 continues to rotate, and the falling raw materials will be scattered and thrown into the kettle body 1, thereby avoiding the situation that when the raw materials at the gap of the paddle 15 fall, the raw materials fall to the same position inside the kettle body 1, which affects the stirring effect, and further improves the puffing reaction efficiency;When the raw materials are evenly distributed inside the kettle 1, the rotating cylinder 14 is driven to move out of the kettle 1, and then the kettle cover 3 is closed, and the liquid catalyst is added to the kettle 1 through the liquid adding pipe 4. The motor 5 27 can drive the stirring shaft 8 to rotate, and the stirring rod 9 is used to stir and mix the raw materials. At the same time, since the scraper 7 is in contact with the inner wall of the kettle 1, the raw materials adhering to the inside of the kettle 1 will be scraped off, thereby avoiding the situation where the raw materials adhere to the inner wall of the kettle 1 and affect the stirring effect. At the same time, the electric heating tube 35 can be used to heat the inside of the kettle 1 to provide temperature conditions for the reaction. At the same time, the pressure port 36 is used to inject the inert gas required for the reaction into the inside of the kettle 1, and the pressure in the kettle 1 is detected in real time. By increasing the pressure in the kettle 1, the water and other volatile components in the biomass raw materials are rapidly evaporated, thereby facilitating the expansion of the biomass raw materials. After the reaction is completed, the valve at the discharge port 6 is opened to discharge the raw materials out of the kettle 1. ;
