Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural waste treatment and feed processing equipment technology, specifically to a straw feed explosion reactor. Background Technology
[0002] Straw is a large amount of waste generated in agricultural production. If it is directly discarded or burned, it will not only waste resources but also pollute the environment. Processing straw into feed is one of the important ways to realize the resource utilization of straw. Straw contains a large amount of cellulose, hemicellulose and other components. Its dense structure makes it difficult for livestock to digest and absorb. Therefore, it is necessary to break its dense structure through pretreatment to improve the palatability and digestibility of the feed.
[0003] Explosion treatment is a commonly used technology for the pretreatment of straw feed. Its principle is to break down the fiber structure of straw through instantaneous pressure changes. However, existing straw feed explosion reactors have several shortcomings: First, the explosion is uneven, often occurring in a single location or direction, resulting in some straw fibers not being effectively destroyed while others are excessively broken, affecting feed quality. Second, the heating efficiency is low and uneven, leading to an unstable pretreatment environment for the straw within the reactor, further impacting the explosion effect. Third, the stirring structure is unreasonable, failing to achieve thorough mixing of the straw and the reaction medium. Therefore, these shortcomings remain.
[0004] In conclusion, it is necessary to invent a straw feed explosion reactor. Summary of the Invention
[0005] To address this issue, the present invention provides a straw feed explosion reactor to solve the problem of uneven explosion, which is often caused by explosions occurring in a single location or direction, resulting in some straw fiber structures not being effectively destroyed while others are excessively crushed, thus affecting feed quality.

[0010] Preferably, each of the outer wall sides of the vessel is provided with a bursting tube, and multiple bursting tubes are evenly arranged on the outer wall sides of the vessel in a ring array, with the upper and lower ends of the bursting tubes on opposite sides connected by a connecting pipe.
[0011] Preferably, each of the inner wall sides of the vessel body is provided with a bursting head at a position corresponding to the bursting tube. The multiple bursting heads are evenly arranged in a ring array. The inner wall sides of the bursting tube are connected to the bursting heads through a connecting pipe. An annular filter frame is fixed on the inner wall side of the vessel body and outside the bursting head. An annular filter screen is embedded on the inner wall side of the annular filter frame.
[0012] Preferably, the outer wall of the vessel is fitted with a heat insulation layer, and the inner wall of the vessel, at a position corresponding to the heat insulation layer, is fitted with a jacketed heating layer for heating the interior of the vessel.
[0013] Preferably, a servo stirring motor is fixed at the center of the top of the outer wall of the vessel lid, and a stirring shaft is fixed at the bottom output end of the servo stirring motor. The bottom end of the stirring shaft passes through the top of the inner wall of the vessel lid and extends into the interior of the vessel body. Spiral stirring rods are fixed at the upper and lower sections of the outer wall of the stirring shaft, and anchor stirring rods are fixed at the outer wall of the stirring shaft and between the upper and lower spiral stirring rods.
[0014] Preferably, a pressure relief pipe is connected to the top of the outer wall of the vessel lid and to the side of the servo stirring motor. An electromagnetic pressure relief valve is fixed to the inner wall of the pressure relief pipe. A pressure relief buffer tank is fixedly connected to the top of the pressure relief pipe. Baffles are fixedly installed on the inner wall of the pressure relief buffer tank and on the side near the pressure relief pipe. The baffles are arranged in an alternating up-and-down manner.

The control system controls the opening and closing of each blasting head, enabling blasting at different locations and in different combinations. This ensures that the straw in each area of the reactor is subjected to uniform blasting force, effectively breaking the fiber structure of the straw and avoiding situations where some straw is not effectively destroyed or some straw is excessively broken, thereby improving feed quality.
[0017] This invention uses a jacketed heating layer to wrap the kettle body, combined with a heat insulation layer, to achieve uniform heating of the kettle body, reduce heat loss, improve heating efficiency, and monitor the heating temperature in real time. The control system precisely adjusts the temperature to ensure that the straw pretreatment is carried out in a suitable temperature environment, further improving the pretreatment effect.
[0018] The mixing assembly of this invention uses three sections of mixing paddles with different structures: an upper, middle and lower section. The propeller-type mixing paddle tumbles the material up and down, while the anchor-type mixing paddle adheres to the reactor wall for mixing. The three work together to achieve thorough mixing of straw and reaction medium, while effectively preventing material from adhering to the reactor wall, thus improving material utilization and equipment cleanliness.

Detailed Implementation
[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] See attached document Figures 1-6 This invention provides a straw feed explosion reactor, comprising a reactor body 100, which is a cylindrical sealed cavity structure made of high-strength stainless steel to ensure it can withstand high-pressure and high-temperature environments (working pressure 0.8-1.2MPa, working temperature 120-150℃). A reactor cover 110 is detachably fixed to the top of the outer wall of the reactor body 100. A feed hopper 130 is installed on one side of the top of the outer wall of the reactor cover 110. Supports are fixed to both sides of the bottom of the outer wall of the feed hopper 130 and to one side of the top of the outer wall of the reactor cover 110. The feed hopper 130 has a funnel-shaped structure and is fixed to one side of the top of the reactor cover 110 by symmetrically arranged supports on both sides. The supports are made of stainless steel. The material is welded and fixed to the top of the vessel lid 110 to ensure that the feed hopper 130 is installed firmly. The bottom of the inner wall of the feed hopper 130 is connected to the top of the vessel lid 110 through the feed pipe. The feed pipe is equipped with a manual or electric control valve to control the feed amount and feed speed. After the feed is completed, the control valve is closed to ensure the sealing performance of the vessel body 100. The feed pipe is equipped with a control valve. A sealing layer 120 is provided between the top of the outer wall of the vessel body 100 and the bottom of the outer wall of the vessel lid 110. The sealing layer 120 is made of high temperature and corrosion resistant rubber material, which is tightly attached to the top end face of the vessel body 100 and the bottom end face of the vessel lid 110 to ensure the airtightness of the vessel body 100 and prevent high pressure steam leakage and material leakage. A discharge mechanism is installed at the bottom of the outer wall of the vessel body 100. The discharge mechanism includes a discharge pipe 140, which is connected to the bottom of the inner wall of the vessel body 100. The discharge pipe 140 is set below the central axis of the vessel body 100, and its top end is sealed to the bottom of the inner wall of the vessel body 100. A valve is provided on the discharge pipe 140 to control the start and stop of discharge. A discharge buffer box 150 is connected to the bottom of the outer wall of the discharge pipe 140. The discharge buffer box 150 is a cuboid or cylindrical cavity structure made of stainless steel. Its function is to buffer the discharge speed of straw after explosion, avoid the instantaneous accumulation of material and the blockage of the pipeline, and reduce dust when the material is discharged. A control discharge pipe is connected to the bottom of the inner wall of the discharge buffer box 150. A valve is provided on the control discharge pipe to finally regulate the discharge of straw feed. The vessel body 100 is equipped with a unique blasting mechanism for detonating straw. This mechanism includes a steam storage tank 300, which is fixed to one side of the outer wall of the vessel body 100 via a bracket. The steam storage tank 300 is a cylindrical pressure vessel, welded to the outer wall of the vessel body 100 by the bracket. The steam storage tank 300 stores high-temperature, high-pressure steam and contains a heating device (such as an electric heating element) that heats water to 150-200℃ to generate high-pressure steam. A booster pump 310 is fixedly connected to the steam outlet at the top of the steam storage tank 300. The booster pump 310 is used to pressurize the steam... The steam in the storage tank 300 is further pressurized to ensure the pressure required for the explosion. The top outlet of the booster pump 310 is connected to a high-pressure gas transmission pipe 320, which is made of high-pressure stainless steel and is used to transport the pressurized steam to the rupture tube 330. Each side of the outer wall of the vessel body 100 is equipped with a rupture tube 330. Multiple rupture tubes 330 are evenly arranged in a ring array on the side of the outer wall of the vessel body 100. The upper and lower ends of the rupture tubes 330 on opposite sides are connected by a connecting pipe. The rupture tube 330 has a circular tubular structure and is arranged parallel to the outer wall of the vessel body 100. The upper and lower ends of each rupture tube 330 on opposite sides are connected by a connecting pipe. The connecting pipes are sealed and welded to the rupture tubes 330 to ensure uniform distribution of steam within each rupture tube 330. A rupture head 332 is installed on the inner wall side of the vessel body 100 at a position corresponding to the rupture tube 330. Multiple rupture heads 332 are evenly arranged in a ring array. The rupture heads 332 can inject high-temperature, high-pressure steam into the interior of the vessel body 100. The injection direction of the rupture heads 332 is towards the center of the vessel body 100 at an angle of 30-45°, ensuring that the steam injection covers the interior of the vessel body 100 without any dead zones. The inner wall side of each rupture tube 330 is connected to the rupture head 332 via a connecting pipe 331. The connecting pipe 331 passes through... The filter is welded to the side wall of the vessel body 100 to ensure no leakage of high-pressure steam. An annular filter frame 333 is fixed to the inner wall side of the vessel body 100 and to the outside of the blasting head 332. An annular filter screen plate is embedded in the inner wall side of the annular filter frame 333. The annular filter frame 333 is an annular frame structure and is welded to the inner wall of the vessel body 100. The filter screen plate is made of stainless steel and has a hole diameter of 1-3mm. It can ensure that the high-pressure steam passes through smoothly and prevent straw debris from entering the blasting head 332, thus avoiding blockage of the blasting head 332 and ensuring stable operation of the blasting mechanism. A heat insulation layer 400 is fitted onto the outer wall side of the vessel body 100. This heat insulation layer 400 has a ring-shaped structure and is made of rock wool or polyurethane insulation material. It tightly wraps the outer wall of the vessel body 100 to reduce heat loss from the interior of the vessel body 100, improve energy efficiency, and prevent operators from being burned by touching the outer wall. A jacketed heating layer 410 is embedded on the inner wall side of the vessel body 100 at a position corresponding to the heat insulation layer 400 to heat the interior of the vessel body 100. This jacketed heating layer 410 has a ring-shaped structure and can be equipped with electric heating wires or through which heating steam is introduced to achieve uniform heating of the interior of the vessel body 100. Uniform heating is achieved by inserting the probe end of a temperature sensor into the vessel body 100 to monitor the internal temperature of the vessel body 100 in real time and transmit the temperature signal to an external controller. The controller automatically adjusts the heating power of the jacketed heating layer 410 according to the preset temperature to ensure that the internal temperature of the vessel body 100 remains stable within the set range. A servo stirring motor 500 is fixed at the center of the top of the outer wall of the vessel lid 110. A stirring shaft 510 is fixed to the bottom output end of the servo stirring motor 500. The bottom end of the stirring shaft 510 passes through the top of the inner wall of the vessel lid 110 and extends into the interior of the vessel body 100. The stirring shaft 510 is a cylindrical stainless steel shaft. Inside the vessel body 100, a sealed bearing is installed at the connection between the stirring shaft 510 and the vessel cover 110. This ensures both the flexible rotation of the stirring shaft 510 and the sealing performance of the vessel body 100. Spiral stirring rods 520 are fixed to both the upper and lower sections of the outer wall of the stirring shaft 510. The upper spiral stirring rod 520 rotates clockwise to push the material in the upper part of the vessel body 100 downwards, while the lower spiral stirring rod 520 rotates counterclockwise to push the material in the lower part of the vessel body 100 upwards. This counterclockwise spiral stirring achieves material tumbling and improves mixing uniformity. Anchor stirring rods 530 are fixed to the outer wall of the stirring shaft 510 between the upper and lower spiral stirring rods 520. The rod 530 has an arc-shaped structure and is set to fit the inner wall of the vessel body 100, with a gap of no more than 5mm between it and the inner wall of the vessel body 100. It is used to stir the material near the vessel wall to prevent the material from adhering to the vessel wall, and at the same time further improve the mixing effect of the material and steam. The top of the outer wall of the vessel lid 110, located on one side of the servo stirring motor 500, is connected to a pressure relief pipe 200. An electromagnetic pressure relief valve is fixed to the inner wall of the pressure relief pipe 200. The pressure relief pipe 200 is a stainless steel pipe, connected to the top side of the vessel lid 110 (located next to the servo stirring motor 500), and sealed and welded to the vessel lid 110. The electromagnetic pressure relief valve is fixed to the inner wall of the pressure relief pipe 200. The electromagnetic pressure relief valve is electrically connected to an external controller and has a fast response speed (≤0).(5 seconds) to achieve rapid pressure relief and ensure the explosive effect. The top of the pressure relief pipe 200 is fixedly connected to the pressure relief buffer tank 210. The pressure relief buffer tank 210 is a cylindrical cavity structure made of stainless steel, used to buffer the high-pressure steam during pressure relief and prevent the steam from directly impacting and damaging the pipeline and valves. Baffles 211 are fixedly installed on the inner wall of the pressure relief buffer tank 210 and on the side close to the pressure relief pipe 200. The baffles 211 are arranged in an alternating manner, and the baffles 211 are rectangular stainless steel plates, arranged in an alternating manner (odd-numbered layers of baffles 211 extend to the left to 1 / 2 of the inner wall of the pressure relief buffer tank 210, even-numbered layers of baffles 211 extend to the right). Extending to half the inner wall of the pressure relief buffer tank 210, forming a labyrinthine channel, the baffle 211 near the pressure relief pipe 200 has an arc-shaped plate 212 fixed to one end. The arc-shaped plate 212 bends inward into the pressure relief buffer tank 210 to guide the steam flow, change the direction of steam movement, and reduce the impact of steam on the baffle 211. The baffle 211 near the pressure relief pipe 200 also has an arc-shaped plate 212 fixed to one end. Multiple flow-slowing plates 213 are installed on the inner wall of the pressure relief buffer tank 210, away from the baffle 211. The flow-slowing plates 213 are rectangular stainless steel plates, arranged at an inclination of 30-60 degrees, with adjacent flow-slowing plates 213 staggered to further decelerate the steam flow. To ensure rapid and stable steam discharge, and to trap any small amount of straw fragments carried in the steam, preventing pipe blockage, an annular water storage tank 620 is provided on the inner wall of the vessel body 100 above the anchor-type stirring rod 530. The annular water storage tank 620 is continuously arranged along the circumference of the inner wall of the vessel body 100, forming an annular groove structure. A flushing nozzle 630 is fixedly connected to the inner wall side of the vessel body 100 at a position corresponding to the annular water storage tank 620. The liquid inlet end of each flushing nozzle 630 is connected to the inner wall side of the annular water storage tank 620, and the flushing nozzles 630 are evenly spaced along the circumference of the annular water storage tank 620. The spray direction covers the inner wall of the vessel body 100, the inner side of the vessel lid 110, and the surface of the stirring mechanism, ensuring thorough rinsing. A cleaning water tank 600, a rectangular or cylindrical tank, is installed on one side of the outer wall of the vessel body 100 to store cleaning water. The tank can be made of stainless steel or food-grade plastic. The drain end of the cleaning water tank 600 is connected to an annular water storage tank 620 via a water pump 610. The water pump 610 delivers water from the cleaning water tank 600 to the annular water storage tank 620, where it is then sprayed through the rinsing nozzles 630 to form a high-pressure water flow. Combined with the low-speed rotation of the stirring mechanism, this achieves comprehensive rinsing of the interior of the vessel body 100.
[0023] The usage process of this invention is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited in advance by the production personnel before production. This invention does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel. First, open the control valve on the feed pipe and slowly feed the straw raw material into the reactor body 100 through the feed hopper 130. The feed amount shall not exceed 70% of the volume of the reactor body 100, leaving enough space for steam circulation and stirring.
[0024] After feeding is completed, close the feed pipe control valve and reconfirm the sealing status of the reactor body 100 through the controller to ensure that there is no air or material leakage.
[0025] Heating and stirring pretreatment The jacketed heating layer 410 is activated, and the heating temperature is set by the controller (adjusted according to the type of straw: 130-135℃ for corn straw, 140-145℃ for wheat straw, and 135-140℃ for rice straw). The heat insulation layer 400 simultaneously plays a heat preservation role, reducing heat loss.
[0026] Start the servo stirring motor 500, set the speed to 30-40 r / min, drive the stirring shaft 510 to rotate, the upper and lower spiral stirring rods 520 drive the straw to circulate and turn up and down, and the anchor stirring rods 530 are in contact with the vessel wall to stir, avoiding material adhesion.
[0027] Temperature sensors monitor the internal temperature of the reactor body 100 in real time. When the temperature reaches the set value, the controller automatically adjusts the output power of the jacketed heating layer 410 to maintain a stable internal temperature. The pretreatment time is 15-20 minutes, which allows the lignin in the straw to soften fully and the hemicellulose to degrade, preparing for subsequent blasting.
[0028] Explosives After pretreatment, the booster pump 310 is started by the controller to transport the high-temperature and high-pressure steam in the steam storage tank 300 to each rupture tube 330 through the high-pressure gas transmission pipe 320. The steam is evenly sprayed into the reactor body 100 from the rupture head 332 of the ring array through the connecting pipe 331, and fully contacts the straw. The pressure inside the reactor rises rapidly to the preset pressure (0.8-1.2MPa).
[0029] Maintain high pressure for 5-10 minutes. During this period, the servo stirring motor 500 can be adjusted to 40-50 r / min to ensure that the steam fully penetrates into the straw fiber.
[0030] The controller quickly opens the electromagnetic pressure relief valve according to the preset program. The high-pressure steam in the reactor enters the pressure relief buffer tank 210 through the pressure relief pipe 200. It is initially buffered by the labyrinth channel formed by the baffle plate 211 and the arc plate 212, and then further decelerated by the slow flow plate 213 before being discharged smoothly. The pressure in the reactor drops to normal pressure within 10-15 seconds. The straw bursts under the action of pressure difference, and the fiber structure is torn.
[0031] (v) Material discharge operation After the blasting is completed, turn off the booster pump 310 and the servo stirring motor 500. After the pressure inside the vessel has completely dropped to atmospheric pressure, open the valve on the discharge pipe 140.
[0032] After blasting, the straw feed enters the discharge buffer box 150 through the discharge pipe 140. After buffering for 5-10 minutes, the valve on the control discharge pipe is opened to discharge and collect the straw feed for subsequent processing steps such as crushing, mixing, and pelleting.
[0033] (vi) Equipment cleaning After the material is discharged, close the discharge pipe 140 and the valve on the control discharge pipe, start the water pump 610, and transport the clean water in the clean water tank 600 to the annular water storage tank 620 through the water pipe.
[0034] Cleaning water is distributed to each rinsing nozzle 630 through the annular water storage tank 620. The nozzles spray high-pressure water flow onto the inner wall of the vessel body 100, the stirring mechanism, and the inner side of the vessel cover 110. At the same time, the servo stirring motor 500 is started and the speed is set to 10-20 r / min to drive the stirring rod to rotate, which helps to rinse the residual material on the inner wall.
[0035] After rinsing for 5-10 minutes, turn off the water pump 610 and the servo stirring motor 500, open the discharge pipe valve 140 to discharge the rinsing wastewater. The wastewater can be collected and treated centrally to avoid environmental pollution.
[0036] After cleaning, the inside of the vessel body 100 can be dried by low-temperature heating (temperature set at 60-80℃) through the jacketed heating layer 410 or by introducing hot air to prevent residual moisture from causing equipment corrosion.
[0037] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
