Description

Technical Field

[0001] This invention relates to the field of straw treatment technology, specifically a straw treatment device for straw fermentation. Background Technology

[0002] Straw, as a common agricultural waste, has always been an important topic in the field of agricultural environmental protection in terms of its treatment and utilization. Straw fermentation is an effective method to convert straw into organic fertilizer or bioenergy, but the straw needs to be thoroughly crushed before fermentation to improve fermentation efficiency and uniformity.

[0003] Existing straw processing devices for straw fermentation suffer from problems such as insufficient crushing precision, inadequate straw tumbling, and low crushing efficiency during the crushing process. This results in straw fragments of varying sizes, affecting the uniformity of subsequent fermentation. Furthermore, existing devices lack intelligent control mechanisms, failing to automatically adjust equipment operation based on the straw crushing status, leading to resource waste or incomplete crushing. In addition, the spraying system has poor coordination with the crushing process, resulting in uneven spraying of the fermenting agent and difficulty in achieving thorough mixing of straw and the fermenting agent. These problems severely restrict the efficiency and quality of straw fermentation. Therefore, there is an urgent need to develop a straw processing device for straw fermentation to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a straw processing device for straw fermentation, so as to solve the problems mentioned in the background art.

[0031] And a feeding rod, which is fixedly connected to the inner wall of the fermentation treatment cylinder and located in the crushed material storage space.

Detailed Implementation

[0058] The technical solutions of the embodiments 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, and 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.

[0059] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0060] Please see Figures 1-10 The present invention provides a straw processing device for straw fermentation, including a straw crushing support 1, a rotating shaft 3 on the straw crushing support 1, and a cross steel frame 4 fixedly installed on the rotating shaft 3;

[0061] The four ends of the cross steel frame 4 are respectively fixedly installed with a crushing cylinder 5, a crushing cylinder 6, a crushing cylinder 7 and a fermentation treatment cylinder 8. The crushing cylinder 5, the crushing cylinder 6, the crushing cylinder 7 and the fermentation treatment cylinder 8 form a square structure and are interconnected through the connecting port 22.

[0062] Among them, crushing equipment is provided on crushing cylinder 5, crushing cylinder 6 and crushing cylinder 7, and the crushing precision of the crushing equipment increases in sequence. Spraying equipment for assisting the subsequent fermentation of straw is provided on fermentation treatment cylinder 8.

[0063] As the self-rotating shaft 3 drives the cross steel frame 4 to slowly rotate on the straw crushing support 1, the straw will be fed into the crushing cylinder 1 5, crushing cylinder 2 6 and crushing cylinder 3 7 in sequence. Under the action of tumbling and the crushing precision increasing in sequence, the straw is fully crushed. Finally, the straw fragments enter the fermentation treatment cylinder 8 in batches and are discharged outside the equipment after being fully sprayed with compound enzyme agent.

[0064] Please see Figure 1 and Figure 2 It also includes: a partition 20, which is fixedly installed inside the crushing cylinder 5;

[0065] The discharge port 9 and the feeding port 10 are fixedly installed on the crushing cylinder 5 and are located on both sides of the partition plate 20, respectively.

[0066] When refining a small amount of straw to ensure a smoother and more thorough subsequent fermentation process, firstly, driven by the rotating shaft 3, the cross steel frame 4 drives the first crushing cylinder 5, the second crushing cylinder 6, the third crushing cylinder 7, and the fermentation treatment cylinder 8 to rotate synchronously clockwise. The rotating shaft 3 can employ a structure combining a shaft and a motor, allowing the first crushing cylinder 5, the second crushing cylinder 6, the third crushing cylinder 7, and the fermentation treatment cylinder 8 to form a square structure, remaining stationary or rotating slowly in a designated position. The operating mode can be selected according to actual needs. When the first crushing cylinder 5 reaches a vertical position and the feeding port 10 opens upwards, a small amount of straw to be crushed can be added into the first crushing cylinder 5. The crushing equipment on crushing cylinder 5 is started to initially crush the straw entering crushing cylinder 5. Since the crushing precision of the crushing equipment on crushing cylinder 5, crushing cylinder 6, and crushing cylinder 7 increases sequentially, only the straw is pre-crushed in crushing cylinder 5 to cut the long strips of straw. The pre-cut straw will enter crushing cylinder 6 through the connecting port 22 between crushing cylinder 5 and crushing cylinder 6. During the crushing process, the overall square structure is always in a slow rotation state, so crushing cylinder 5 and crushing cylinder 6 will gradually tilt. Under the tumbling action of the cylinder, the straw in the cylinder will also tumble while being crushed (in subsequent crushing operations). In the process, both crushing cylinders 6 and 7 undergo a crushing process of tilting-verticaling-re-tilting. Through these two tilting processes, the straw inside the cylinders tumbles during crushing, which further improves the crushing effect. This ensures thorough crushing of the straw. The crushing equipment on crushing cylinder 6 only starts working when it is tilted, which helps save resources (the crushing equipment on crushing cylinder 5 automatically stops when it moves from a vertical to a horizontal position). The optimal crushing effect is achieved through the successive increases in tumbling and crushing precision. The thoroughly crushed straw finally enters the fermentation chamber through the connection port 22 between crushing cylinder 7 and fermentation cylinder 8. Inside the processing cylinder 8, as straw fragments are sequentially discharged into the fermentation processing cylinder 8, the fermentation processing cylinder 8 gradually tilts from the lowest end of the cross steel frame 4 (when the spraying equipment is activated). The fragments will slide in batches to the bottom of the fermentation processing cylinder 8. As the fragments in the crushing cylinder 3 7 flow into the bottom of the fermentation processing cylinder 8, the spraying equipment sprays the compound enzyme solution onto the flowing fragments. Finally, the processed fragments will enter the crushing cylinder 1 5 through the connecting port 22 between the fermentation processing cylinder 8 and the crushing cylinder 1 5, and be discharged from the outside of the equipment through the discharge port 9. This achieves thorough crushing of the straw, improves the crushing accuracy, and is fully automated, providing convenience for the staff.

[0067] In one embodiment of the present invention, please refer to Figures 1-10It also includes: a drive device 13, the number of which is four, and the four drive devices 13 are respectively located on the first crushing cylinder 5, the second crushing cylinder 6, the third crushing cylinder 7 and the fermentation treatment cylinder 8;

[0068] The control system 12 is fixedly installed on the straw crushing support 1 and electrically connected to the drive device 13;

[0069] And a timing control component, which is connected to the rotation axis 3 and electrically connected to the control system 12.

[0070] The timing control component includes:

[0071] The orientation detection controller 2, there are four orientation detection controllers 2, which are evenly distributed around the rotation axis 3 and electrically connected to the control system 12, and are used to control the start and stop time and sequence of the four drive devices 13 respectively.

[0072] Placement slot 35, which is formed on the orientation detection controller 2;

[0073] And an elastic support rod 34 and a detection plate 36, both of which are fixedly installed in the placement groove 35. A gravity ball 37 is also fixedly installed on the elastic support rod 34.

[0074] As the spin shaft 3 rotates, when the gravity ball 37 is in an inclined state, the gravity ball 37 will overcome the elasticity of the elastic support rod 34 and press the gravity ball 37 onto the detection plate 36, thereby controlling the corresponding drive device 13 to start.

[0075] The four drive devices 13 can drive the crushing equipment and other components inside the cylinder to rotate, thereby coordinating to fully crush the straw. During the slow rotation of the cross steel frame 4 driven by the rotating shaft 3, the position of the orientation detection controller 2 on the rotating shaft 3 changes constantly. When the gravity ball 37 generates a component force towards the detection plate 36, the elastic support rod 34 bends under the influence of the gravity component of the gravity ball 37, ultimately pressing the gravity ball 37 firmly onto the detection plate 36. When the detection plate 36 detects gravity, the operating system 12 controls the corresponding drive device 13 to start (at this time, the cylinder is in a certain tilt state; the specific tilt state at which the drive device 13 starts can be determined by setting the trigger value of the pressure sensor on the detection plate 36; alternatively, the rotation of the drive device 13 can be gradually increased based on the pressure value detected by the detection plate 36). The speed is such that, in the initial stage of the drive device 13's rotation, the drive device 13 rotates slowly to achieve auxiliary feeding (this will not be elaborated on here). After the drive device 13 starts, it will drive the corresponding crushing equipment or other equipment in the cylinder to start, thereby completing the crushing operation of straw. Under the continuous rotation of the spin shaft 3, the gravity ball 37 will eventually separate from the detection plate 36. For example, when the gravity ball 37 is in the vertical quadrant position, or when the gravity ball 37 generates a component force in the direction away from the detection plate 36, the gravity ball 37 will not contact the detection plate 36. At this time, the detection plate 36 controls the corresponding drive device 13 to stop through the operating system 12, thereby realizing the change of position state of the orientation detection controller 2 as it rotates with the spin shaft 3, thereby changing the contact state between the detection plate 36 and the liquid detector 27, ultimately achieving the purpose of controlling the start and stop of the drive device 13, thereby saving resources while fully crushing the straw.

[0076] In one embodiment of the present invention, please refer to Figures 1-10 The pulverizing equipment includes:

[0077] The first crushing shaft 17 and the second crushing shaft 24 are rotatably installed inside the first crushing cylinder 5. There are two second crushing shafts 24, which are located inside the second crushing cylinder 6 and the third crushing cylinder 7, respectively.

[0078] Among them, multiple crushing blades 18 are provided on both the first crushing shaft 17 and the second crushing shaft 24, and the number of crushing blades 18 distributed on the first crushing shaft 17 and the two second crushing shafts 24 increases sequentially.

[0079] And screening brackets 19, there are three screening brackets 19, the three screening brackets 19 are respectively installed in the first crushing cylinder 5, the second crushing cylinder 6 and the third crushing cylinder 7, and are set near the communication port 22, and the screening brackets 19 are also rotatably connected to the first crushing shaft 17 and the second crushing shaft 24 respectively.

[0080] It also includes: a feeding chamber 23, there are two feeding chambers 23, the two feeding chambers 23 are located in the second crushing cylinder 6 and the third crushing cylinder 7 respectively, and both are connected to the communication port 22;

[0081] Each of the feeding chambers 23 is provided with a spiral blade 25, and two spiral blades 25 are respectively fixedly installed on two crushing shafts 24.

[0082] It also includes: a feeding tooth 21, which is fixedly installed on the crushing shaft 17 and located on the upper side of the partition plate 20;

[0083] And a side positioning device 11, which is fixedly installed on the straw crushing support 1 and is detachably connected to the cross steel frame 4.

[0084] When the straw is being crushed, the crushing shaft 17 drives the crushing blades 18 to rotate, achieving initial crushing of the straw. The crushing shaft 24 drives more crushing blades 18 to rotate, achieving further fine processing of the straw fragments. In addition, the screening support 19 ensures that the straw is discharged into the next cylinder only when it reaches a certain degree of crushing. This increases the crushing effect and avoids damage to the next stage of crushing equipment. When the cylinder returns to a horizontal state from its tilted position (i.e., when it reaches the highest point of the cross steel frame 4 and is in a horizontal state, this stage of crushing is completed), if a large amount of straw fragments remain in the cylinder, the sensor can detect this and cause the rotating shaft 3 to drive the cross steel frame 4 to reverse, continuing to crush the straw remaining in the previous cylinder until it is all discharged into the next cylinder.

[0085] When straw fragments are discharged into the next cylinder through the connecting port 22, they first enter the feeding chamber 23. In the initial stage, the drive device 13 drives the second crushing shaft 24 to rotate slowly, thereby driving the spiral blades 25 to rotate synchronously, so that the raw materials in the feeding chamber 23 are gradually discharged into the second crushing cylinder 6 (or the third crushing cylinder 7), avoiding blockage. In addition, the side positioning device 11 is provided. The side positioning device 11 can be in the form of a hydraulic device and can have an arc-shaped structure, so that when the entire equipment needs to be stopped or fixed in a certain position according to the actual operation needs, the side positioning device can be positioned to allow the equipment to be stopped or fixed in a certain position. When the positioning device 11 is activated, it can clamp the cross steel frame 4 to further improve the stability of the overall equipment. During the final discharge, the crushing shaft 17 will drive the feeding teeth 21 to rotate slowly, so that the crushed material that enters the crushing cylinder 5 through the connecting port 22 will be discharged to the outside of the equipment through the discharge port 9 (under the blocking effect of the partition 20, the crushed material will not re-enter the crushing area in the crushing cylinder 5, wherein the crushing shaft 17 passes through the partition 20 and is rotatably connected to the partition 20). Under the continuous rotation of the feeding teeth 21, the crushed material at the discharge port 9 is prevented from being blocked, and the discharge of the crushed material can be accelerated.

[0086] In one embodiment of the present invention, please refer to Figures 1-10 It also includes: a rotating shaft 30, which is rotatably installed inside the fermentation treatment cylinder 8 and located near the communication port 22;

[0087] The blocking plate 32 is fixedly installed on the rotating shaft 30 and rotatably connected to the fermentation treatment cylinder 8. The blocking plate 32 is also provided with a feeding notch 33.

[0088] The blockage plate 32 and the end of the fermentation treatment cylinder 8 form a material storage space, which is connected to the communication port 22, and the rotating shaft 30 is located in the material storage space.

[0089] And a feeding rod 31, which is fixedly connected to the inner wall of the fermentation treatment cylinder 8 and located in the crushed material storage space.

[0090] The spraying equipment includes:

[0091] The liquid storage tank 14 is fixedly installed on the fermentation treatment cylinder 8, and the liquid storage tank 14 is also provided with a liquid injection port 15.

[0092] Liquid detector 27, there are multiple liquid detectors 27, and the multiple liquid detectors 27 are evenly distributed on the inner bottom wall of the liquid storage tank 14;

[0093] And a spray control component, which is connected to the liquid storage tank 14 and electrically connected to the liquid detector 27.

[0094] The spray control component includes:

[0095] A jet pump 16 is fixedly installed on the liquid storage tank 14, and the suction port of the jet pump 16 is located inside the liquid storage tank 14.

[0096] An annular spray plate 28 is located inside the storage tank 14 and extends into the fermentation treatment cylinder 8. The annular spray plate 28 is provided with a plurality of spray holes 26, all of which are located inside the fermentation treatment cylinder 8.

[0097] And a delivery pipe 29, the two ends of which are connected to the outlet of the jet pump 16 and the nozzle 26, respectively.

[0098] During the process of the crushed material entering the fermentation treatment cylinder 8 through the connection port 22 between the crushing cylinder 7 and the fermentation treatment cylinder 8, the crushed material first enters the crushed material storage space. At this time, due to the blocking effect of the blocking plate 32, the crushed material will not enter the spraying space in large quantities (when the fermentation treatment cylinder 8 is in a vertical state, the spraying space in the fermentation treatment cylinder 8 corresponding to the spraying equipment is located below the blocking plate 32). As the fermentation treatment cylinder 8 tilts from a horizontal state (at this time, the fermentation treatment cylinder 8 is located at the lowest end of the cross steel frame 4), the corresponding orientation detection controller 2 controls the spraying equipment and the corresponding drive equipment 13 to be powered on (at this time, the spraying equipment and the drive equipment 13 are not started). As the fermentation treatment cylinder 8 continues to rotate, when the liquid in the storage tank 14 completely covers the multiple liquid detectors 27 (that is, when all liquid detectors 27 detect liquid), when the fermentation treatment cylinder 8 is in other positions, because the storage tank 14 cannot be completely filled through the liquid injection port 15, such as... Figure 2As shown, at this time, a portion of the upper space of the storage tank 14 is empty of liquid. Therefore, the liquid detector 27 located at the top of the storage tank 14 is not submerged in the liquid, and the corresponding orientation detection controller 2 has not reached the designated position. The spraying equipment is not powered on and does not start spraying. As the fermentation treatment cylinder 8 continues to rotate, at least one liquid detector 27 will always be unsubmerged in the liquid. At this time, the spraying equipment is powered on and started, and the corresponding drive device 13 is also started. Thus, under the action of the material feeding rod 31 and the material spreading notch 33, the crushed material in the crushing cylinder 7 and the crushed material temporary storage space gradually falls to the bottom of the fermentation treatment cylinder 8. During the flow of the crushed material falling in batches, a compound enzyme solution (the compound enzyme can be in the form of a compound solution of cellulase, hemicellulase, ligninase and pectinase, etc.) is sprayed into the fermentation treatment cylinder 8 through multiple spray holes 26, thereby realizing the processing of the crushed material, so as to facilitate better subsequent fermentation and provide convenience for the staff.
