Description

Technical Field

[0001] The invention relates to the technical field of biochar production, and in particular to a pretreatment device for raw materials used for improving saline-alkali soil. Background Art

[0002] Due to the high salt or alkalinity, saline-alkali land makes it difficult for crops to grow, forming wasteland, which seriously wastes land resources. In order to promote the transformation of saline-alkali land and turn wasteland into fertile land, saline-alkali land improvers will be used to improve the land;

[0003] Biochar is a porous aromatic substance obtained by pyrolysis of agricultural and forestry wastes such as rice husks, bamboo, straw, etc. under high temperature, anaerobic or oxygen-limited conditions. As a soil conditioner, biochar has a significant effect on the physical, chemical and biological properties of saline-alkali soils. Biochar has a high adsorption capacity. When applied to saline-alkali soils, it can reduce plant sodium absorption by instantaneously combining with Na+, thereby increasing soil moisture content and reducing osmotic stress, and releasing mineral nutrients (especially K+, Ca2+, Mg2+) into the soil solution. When producing biochar, these raw materials will be doped with a large amount of impurities, which will have a certain impact on the properties of the biochar after carbonization. Therefore, the raw materials need to be pretreated before processing.

[0004] In the prior art, a biochar preparation furnace based on intelligent spraying of soil physical and chemical properties is disclosed with publication number CN116855264A. The purpose of cleaning the inside of the carbonization furnace is achieved by providing a scraper, a liquid storage tank and a gathering scraper. The scraper is driven to rotate during the rotation of the support ring, and the liquid medicine is sprayed out through the spray hole and mixed with the biochar. The biochar absorbs the liquid and adheres to the outside of the storage bin and the liquid storage tank. The scraper rotates to clean the biochar attached to the inner wall of the liquid storage tank and the storage bin, thereby preventing the biochar from absorbing the liquid and failing to fall, affecting the full mixing of the biochar and the liquid medicine. At the same time, the manual cleaning of the inside of the storage bin is reduced, and the mixing effect of the biochar and the liquid medicine is improved, thereby achieving the effect of cleaning the inside of the carbonization furnace.

[0005] Although the cleaning mechanism can clean the inner wall of the preparation furnace, there are still some defects in actual use. After the carbonized straw or rice husk is sprayed with liquid medicine and cooling water, the rice husk will become easy to stick together and adhere to the inner wall of the furnace and the scraper. However, the cleaning mechanism can only clean the inner wall of the carbonization furnace. During the cleaning process, the rice husk will adhere to the scraper, so that workers are required to clean the scraper when discharging, which is not only time-consuming and labor-intensive, but also greatly reduces the production efficiency of the device.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1-9A pretreatment device for raw materials for improving saline-alkali soil shown in the figure comprises a carbonization cylinder 1 and a carbonization furnace 2 arranged at the middle position inside the carbonization cylinder 1, a fixed frame 3 is arranged below the carbonization cylinder 1, both sides of the outer wall of the carbonization cylinder 1 are rotatably connected to the inner side of the fixed frame 3 through a rotating shaft, and a round frame 5 is fixedly connected to the top of the carbonization cylinder 1 through three supporting legs 4, a winding roller 6 is rotatably connected to the top of the inner side of the round frame 5, a pull rope 7 is wound around the outer wall of the winding roller 6, one end of the pull rope 7 is fixedly connected to the outer wall of the winding roller 6, and an adjustment frame 8 is fixedly connected to the side wall of the carbonization cylinder 1, a T-shaped plate 9 is slidably connected to the inner side of the adjustment frame 8, and an annular plate 10 is arranged at the bottom end of the carbonization cylinder 1;

[0034] A U-shaped plate 11 is fixedly connected to the top of the annular plate 10, and the other end of the U-shaped plate 11 is slidably connected to the inner side of the adjusting frame 8, and a slide groove 12 is provided on the side wall of the U-shaped plate 11, and a movable plate 13 is slidably connected to the inner side of the slide groove 12, and an upper spring 14 is fixedly connected between the top of the movable plate 13 and the inner top of the slide groove 12, a push block 15 is fixedly connected to the side wall of the T-shaped plate 9, and a side plate 16 is fixedly connected to the side wall of the movable plate 13, and a straight rod 17 is slidably connected to the side wall of the side plate 16 and above the push block 15, and a driving mechanism for driving the T-shaped plate 9 to slide up and down is provided on the adjusting frame 8, a scraper 18 is provided under the winding roller 6, and a top plate is slidably connected to the inner side of the adjusting frame 8 and above the carbonization cylinder 1 19, and the top plate 19 is arranged above the T-shaped plate 9, and a through slot 20 is opened on the side wall of the adjusting frame 8 and the circular frame 5 and at a position corresponding to the top plate 19, the other end of the pull rope 7 passes through the through slot 20 and is fixedly connected to the side wall of the top plate 19, and a reset spring 40 is fixedly connected between the inner side of the adjusting frame 8 and the top of the U-shaped plate 11, and the reset spring 40 facilitates pushing the U-shaped plate 11 to reset. It should be noted that the elastic force of the reset spring 40 is set to be smaller than the elastic force of the upper spring 14, ensuring that the U-shaped plate 11 will not move downward under the pressure of the upper spring 14, and even if it moves downward slightly, it will move upward under the gradual pressure of the upper spring 14, ensuring that the annular plate 10 is completely cleaned;

[0035] The driving mechanism includes a driving motor 25, which is fixedly connected to the bottom end of the adjusting frame 8. A bidirectional screw rod 26 is rotatably connected to the inner side of the adjusting frame 8, and the bidirectional screw rod 26 is threadedly connected to the inner side wall of the T-shaped plate 9. The output of the driving motor 25 passes through the bottom end of the adjusting frame 8 and is fixedly connected to the bottom of the bidirectional screw rod 26. An inward groove 21 is provided at the top of the winding roller 6, and a vortex spring 22 is provided inside the groove 21. One end of the vortex spring 22 is fixedly connected to the inner side of the groove 21, and the other end of the vortex spring 22 is fixedly connected to the inner top of the circular frame 5. Through the arrangement of the groove 21 and the vortex spring 22, it is convenient to pull the pull rope 7 back, thereby driving the scraper 18 to reset.

[0036] When the raw materials in the carbonization cylinder 1 are initially carbonized, the rotating motor 39 can be controlled to start and turn the carbonization cylinder 1 over to pour out the raw materials. Then, the driving motor 25 can be controlled to start and drive the bidirectional screw rod 26 to rotate, thereby driving the threaded T-plate 9 to slide, and then the straight rod 17, the upper block 30, the lower block 29 and the U-plate 11 are driven by the push block 15 to slide upward at the same time, thereby driving the annular plate 10 to slide on the inside of the carbonization cylinder 1, and gradually compressing the return spring 40, so that the raw materials adhered to the inside of the carbonization cylinder 1 are scraped off by the sliding of the annular plate 10, and the right-angle block 37 is driven to move to push out the scraper 18, and then the annular plate 10 moves with the end of the carbonization cylinder 1;

[0037] At this time, the straight rod 17 moves to the side of the slot 31, and the elastic force of the lower spring 28 pushes the straight rod 17 to slide into the slot 31, and at the same time drives the lower block 29 to move out of the side of the upper block 30, and then the T-shaped plate 9 pushes the straight rod 17 to drive the movable plate 13 to slide upward, gradually compressing the upper spring 14. At this time, the annular plate 10 is restricted by the scraper 18, and the U-shaped plate 11 cannot move upward. At the same time, the T-shaped plate 9 moves to the bottom of the top plate 19, and then pushes the top plate 19 to slide upward, thereby pulling the pull rope 7 to gradually rotate out of the winding roller 6. Since the other end of the pull rope 7 is fixed on the winding roller 6, it will drive the winding roller 6 to rotate;

[0038] This drives the scraper 18 below to rotate on the annular plate 10 to scrape off the cleaned biochar raw materials. At the same time, since one end of the spiral spring 22 is fixed in the groove 21 and the other end is fixed to the top of the circular frame 5, the spiral spring 22 will be gradually compressed by the rotation of the winding roller 6, and then the T-plate 9 moves to the top of the bidirectional screw rod 26, and is driven downward by the bidirectional screw rod 26, so that the above operation is repeated in reverse to reset, thereby achieving a comprehensive cleaning of the inner wall of the carbonization cylinder 1, and at the same time cleaning the biochar raw materials adhered to the surface of the scraper 18, so that after use, only the biochar raw materials adhered to the surface of the blocking frame 38 need to be cleaned.

[0039] In order to improve the smoothness during the operation of the device, an upper guide roller 23 is longitudinally rotatably connected to the inner side of the through groove 20 and close to the round frame 5, and a lower guide roller 24 is transversely rotatably connected to the top of the inner side of the through groove 20 and close to the top plate 19, and the pull rope 7 passes through the outer walls of the upper guide roller 23 and the lower guide roller 24 respectively;

[0040] The upper guide roller 23 and the lower guide roller 24 can play a guiding role in the pulling process of the pull rope 7 and guide the moving direction of the pull rope 7, thereby avoiding friction between the pull rope 7 and the corner of the through groove 20, causing damage to the pull rope 7 and affecting the service life of the device.

[0041] In order to improve the stability of the device during operation, a guide rod 27 is fixedly connected to the inner side of the adjustment frame 8, and the guide rod 27 is arranged through the bottom end of the T-shaped plate 9. Through the setting of the guide rod 27, it can play a guiding role in the process of the T-shaped plate 9 moving when the two-way screw rod 26 rotates, avoiding the T-shaped plate 9 from rotating with the two-way screw rod 26, thereby improving the stability of the device during operation.

[0042] In order to ensure that the U-shaped plate 11 can be driven to move upward when the T-shaped plate 9 moves upward, a lower spring 28 is fixedly connected between the side wall of the side plate 16 and the outer wall of the straight rod 17, and the side wall of the straight rod 17 abuts against the inner side of the adjustment frame 8. The end of the straight rod 17 is set to a smooth arc surface, and a lower block 29 is fixedly connected to the side wall of the straight rod 17. An upper block 30 is fixedly connected to the side wall of the U-shaped plate 11 and located above the lower block 29. A card slot 31 is opened on the inner side of the adjustment frame 8 and located above the carbonization cylinder 1. The card slot 31 is set above the straight rod 17, and the bottom of the card slot 31 is tilted. The tilted setting facilitates the straight rod 17 to slide out when it is reset;

[0043] When the device is in the initial position, the lower block 29 is located below the upper block 30, so that when the T-plate 9 pushes the straight rod 17 to move, the U-plate 11 will be driven to move. Then, when the annular plate 10 moves to the top of the carbonization cylinder 1, the straight rod 17 will move to the side of the slot 31 under the elastic force of the lower spring 28, thereby moving the lower block 29 out from under the upper block 30, thereby losing the thrust on the U-plate 11.

[0044] In order to avoid affecting the normal operation of the device, a movable groove 32 is opened at the top of the circular frame 5 and corresponds to the U-shaped plate 11. The setting of the movable groove 32 can avoid blocking the upward sliding of the U-shaped plate 11, thereby affecting the normal cleaning of the carbonization cylinder 1, and a top groove 33 adapted to the annular plate 10 is opened at the bottom of the circular frame 5. The top groove 33 can avoid hindering the sliding of the scraper 18 on the annular plate 10, thereby affecting the normal cleaning of the annular plate 10.

[0045] In order to be able to clean up the biochar raw materials adhered to the surface of the scraper 18 after the scraper 18 has cleaned the carbonization cylinder 1, an inward telescopic groove 34 is opened at the bottom of the winding roller 6, and a bottom plate 35 is fixedly connected to the top of the scraper 18. A compression spring 36 is fixedly connected between the side wall of the bottom plate 35 and the inner side of the telescopic groove 34, and a right-angle block 37 is fixedly connected to the top of the U-shaped plate 11. It should be noted here that the side of the U-shaped plate 11 that squeezes the scraper 18 is an arc surface, so as to ensure that the scraper 18 still maintains squeezing during rotation, so that the position of the scraper 18 does not change. A blocking frame 38 is fixedly connected to the bottom of the winding roller 6 and located on the outer wall of the scraper 18. The blocking frame 38 is convenient for scraping off the biochar raw materials adhered to the outer side of the scraper 18. When cleaning, it is only necessary to clean the biochar raw materials adhered to the side wall of the blocking frame 38, thereby reducing the scope of manual cleaning and improving the convenience of the device. The inner side of the blocking frame 38 fits the outer side of the scraper 18.

[0046] When the driving mechanism is running to clean the inner wall of the carbonizing cylinder 1, the upward movement of the U-shaped plate 11 drives the right-angle block 37 to slide upward, thereby squeezing the side wall of the scraper 18 through the inclined surface of the right-angle block 37, and then pushing the scraper 18 to slide on the blocking frame 38, and at the same time driving the bottom plate 35 to move, thereby gradually compressing the compression spring 36, and then pushing the scraper 18 out of the top of the inverted annular plate 10, and then the U-shaped plate 11 continues to move upward, and the side wall of the scraper 18 is squeezed by the side wall of the U-shaped plate 11 to limit its position, and then the driving mechanism moves the annular plate 10 to the bottom of the scraper 18;

[0047] Subsequently, the scraper 18 is driven to rotate along with the winding roller 6 by the continued operation of the driving mechanism. At this time, the scraper 18 moves to the top groove 33, so that the scraper 18 is driven by the winding roller 6 to move out of the side wall of the U-shaped plate 11 to the side wall of the top groove 33, and then continues to rotate under the extrusion of the top groove 33, ensuring the scraping of the biochar raw materials adhered to the top of the annular plate 10. Subsequently, during the resetting process after the cleaning is completed, the U-shaped plate 11 drives the right-angle block 37 to be reset, which will gradually release the extrusion of the scraper 18, and then the scraper 18 is pushed to reset under the thrust of the compression spring 36. At the same time, the biochar raw materials adhered to the side wall of the scraper 18 can be scraped off through the blocking frame 38, so that the side wall of the blocking frame 38 can be cleaned after the production is completed.

[0048] In order to automatically pour out the carbonized raw materials, a rotating motor 39 is fixedly connected to the side wall of the fixed frame 3, and the output end of the rotating motor 39 passes through the side wall of the fixed frame 3 and is fixedly connected to the rotating shaft of the side wall of the carbonization cylinder 1;

[0049] When the carbonization of the biochar raw material is completed, the rotating motor 39 can be controlled to start, thereby driving the carbonization cylinder 1 to rotate between the fixed frames 3, so as to pour out the carbonized raw materials in the carbonization cylinder 1. After the pouring is completed, the rotating motor 39 can be controlled to rotate in the reverse direction to drive the carbonization cylinder 1 to rotate back, thereby further improving the production efficiency of the device.

[0050] The basic principles, main features and advantages of the present invention are shown and described above.

[0051] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
