Description

Technical Field

[0001] The present application relates to the field of drying equipment, and in particular to a soybean processing drying equipment. Background Art

[0002] Fresh soybeans usually contain more water. If they are directly peeled, the bean kernels and the bean skins are likely to stick together, affecting the overall peeling effect of the soybeans. Therefore, before the soybeans are peeled, they usually need to be preheated and dried to reduce the overall water content of the soybeans.

[0003] At present, the drying process of soybeans is usually completed in an oven. Specifically, the soybeans to be processed are placed in a tray and spread out, and then the tray with soybeans is sent into the oven, and the oven dries the soybeans in the tray. After the oven completes drying the soybeans, the tray is removed from the oven and the soybeans in the tray are transferred.

[0004] With respect to the above-mentioned related technologies, the process of using an oven to dry soybeans has complicated steps as a whole and is inconvenient to operate. Therefore, there is room for improvement. Summary of the invention

[0005] In order to facilitate the drying process of soybeans, the present application provides a soybean processing and drying equipment.

[0006] The soybean processing and drying equipment provided in this application adopts the following technical solution: A soybean processing and drying equipment comprises a drying box, wherein the bottom and top of the drying box are respectively connected with an air inlet pipe and an air outlet pipe, and the air outlet pipe is connected with a fan; one end of the drying box is vertically connected with a feed pipe upward, and the other end of the drying box is vertically connected with a discharge pipe downward; a conveying assembly and a heating assembly are arranged in the drying box; the conveying assembly comprises a chain conveyor, and the chain conveyor is located between the air inlet pipe and the air outlet pipe; the input end of the chain conveyor extends to below the feed pipe, and the output end of the chain conveyor extends to above the discharge pipe; the chain conveyor comprises an annular conveying chain plate, and a plurality of ventilation holes are evenly distributed on the annular conveying chain plate; the heating assembly is used for heating the inner cavity of the drying box.

[0007] By adopting the above technical solution, after the soybeans to be dried fall into the input end of the chain conveyor through the feed pipe, the chain conveyor transports the soybeans from the input end to the output end. During this period, the soybeans in the drying box are heated by the heating component, and at the same time, the fan at the air outlet draws the external air into the drying box through the air inlet and discharges it through the air outlet to form an upward airflow in the drying box. The upward airflow is used to bring the moisture generated after heating the soybeans out of the air outlet pipe in time to achieve the drying of the soybeans. Compared with the traditional method of drying soybeans in an oven, it is conducive to improving the convenience and overall efficiency of soybean drying. At the same time, small particle impurities carried in the soybeans, such as broken beans, can fall into the bottom of the drying box through the ventilation holes on the annular conveying chain plate during the transportation of the chain conveyor, so as to achieve partial screening of small particle impurities contained in the soybeans.

[0008] Preferably, the heating assembly includes a plurality of heating pipes horizontally arranged in the inner cavity of the drying box, the plurality of heating pipes are all located on the inner periphery of the annular conveying chain plate, and the plurality of heating pipes are evenly distributed along the length direction of the chain conveyor, the heating pipes are radially connected to a plurality of nozzles, and the nozzles are all vertically arranged upward.

[0009] By adopting the above technical solution, after the heat source such as steam or hot air is introduced into the heating pipe, it can be directly sprayed upward through the nozzles on the outer periphery of the heating pipe, and act on the surface of the soybeans through the ventilation holes on the annular conveyor chain plate, so as to achieve direct heating of the soybeans. By setting the nozzles on the outer periphery of the heating pipe vertically upward, it is beneficial to keep the heat source such as steam and the rising airflow in the drying box in the same flow path, so that the rising airflow can better carry the moisture generated by the heated soybeans out of the air outlet pipe in time, and at the same time reduce the airflow turbulence in the drying box, which affects the drying effect of the soybeans, so that the heating component can heat and dry the soybeans transported by the chain conveyor more evenly.

[0010] Preferably, the inner cavity of the drying box is also provided with a material equalizing assembly, which includes a plurality of material equalizing parts, and the plurality of material equalizing parts are located above the chain conveyor and are evenly distributed along the length direction of the chain conveyor; the material equalizing part includes a horizontally arranged support rod, and a material equalizing rod is vertically connected to the bottom of the support rod, and a gap is left between the bottom end of the material equalizing rod and the annular conveying chain of the chain conveyor; the material equalizing rods of adjacent material equalizing parts are staggered.

[0011] By adopting the above technical solution, while the soybeans are being transported on the chain conveyor, the staggered leveling rods of adjacent leveling parts are used to spread and flatten the soybeans on the circular conveyor chain, thereby reducing the accumulation of soybeans on the circular conveyor chain, resulting in uneven heating between the soybeans and affecting the drying effect of the soybeans.

[0012] Preferably, a cleaning assembly is also provided in the drying box, and the cleaning assembly includes a plurality of cleaning air knives, and the plurality of cleaning air knives are located on the inner periphery of the annular conveying chain of the chain conveyor, and the plurality of cleaning air knives are evenly distributed along the length direction of the chain conveyor, and the air outlets of the cleaning air knives are all arranged vertically downward.

[0013] By adopting the above technical solution, during the operation of the chain conveyor, compressed air is continuously blown to the circular conveyor chain plate through a number of cleaning wind knives located on the inner circumference of the circular conveyor chain plate, so as to blow some small particle impurities stuck in the ventilation holes downward to the bottom of the drying box, thereby reducing the clogging of the ventilation holes on the circular conveyor chain plate by small particle impurities and affecting the ventilation effect of the circular conveyor chain plate.

[0014] Preferably, the inner cavity of the drying box is further provided with a scraper air knife, the scraper air knife is located below the output end of the chain conveyor, and the air outlet of the scraper air knife is arranged toward the annular conveying chain of the chain conveyor.

[0015] By adopting the above technical solution, some soybeans are easily stuck in the ventilation holes of the ring conveyor chain due to their volume, which makes it difficult for them to fall off the ring conveyor chain when they move with the ring conveyor chain to the output end of the chain conveyor; by setting the scraper wind knife, during the subsequent operation of the chain conveyor, the scraper wind knife continuously blows compressed air toward the ring conveyor chain at the output end of the chain conveyor to blow the soybeans stuck in the ventilation holes of the ring conveyor chain away from the ring conveyor chain, thereby reducing the situation where the ventilation holes are blocked by the soybeans and affect the air permeability of the ring conveyor chain.

[0016] Preferably, a material guide plate is further supported in the drying box, and the material guide plate is arranged obliquely, the inclined upper end of the material guide plate extends to the bottom of the scraping air knife, and the inclined lower end of the material guide plate extends into the discharge pipe.

[0017] By adopting the above technical solution, the soybeans blown off by the scraping air knife can slide directly into the discharge pipe through the guide plate, which is helpful to limit the soybeans blown off from the annular conveyor chain plate through the scraper plate from falling to the bottom of the drying box.

[0018] Preferably, a screw conveyor is also supported at the bottom of the drying box, and the inner cavity of the drying box is connected to the inner cavity of the screw conveyor.

[0019] By adopting the above technical solution, when the chain conveyor is conveying soybeans, small particles of impurities carried in the soybeans fall into the bottom of the drying box through the ventilation holes on the annular conveying chain of the chain conveyor, and can be discharged in time through the screw conveyor at the bottom of the drying box, which is helpful to reduce the accumulation of small particles of impurities at the bottom of the drying box, causing difficulty in cleaning.

[0020] Preferably, a plurality of impact rods are horizontally arranged in the inner cavity of the air inlet pipe.

[0021] By adopting the above technical solution, by arranging impact rods in the air inlet pipe, the subsequent soybeans can collide with several impact rods in the inner cavity of the air inlet pipe when falling into the feed pipe, which is conducive to better separating small particle impurities such as broken beans adhering to the surface of the soybeans from the surface of the soybeans, so that after the subsequent soybeans fall onto the chain conveyor, the small particle impurities can better fall into the bottom of the drying box through the ventilation holes on the annular conveying chain on the chain conveyor, thereby reducing the subsequent small particle impurities that are discharged from the discharge pipe along with the soybeans.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. While the soybeans are being transported by the chain conveyor, the soybeans conveyed by the chain conveyor belt are heated by the heating component located in the drying box. During this period, the fan at the outlet duct draws the external air into the drying box through the air inlet duct and draws it out through the outlet duct to form an upward airflow in the drying box. The moisture generated by the heated soybeans is entrained by the upward airflow and discharged from the air outlet at the top of the drying box. After the dried soybeans are transported to the output end by the chain conveyor, they are automatically discharged through the discharge pipe, which is conducive to improving the convenience of soybean drying processing.

[0023] 2. By setting a material leveling component above the chain conveyor, when the soybeans falling through the feed pipe are subsequently transported by the chain conveyor, the soybeans on the annular conveyor chain can be spread and flattened by the material leveling rods staggered in adjacent material leveling parts, so that the soybeans can be evenly heated.

[0024] 3. Several cleaning air knives are arranged on the inner periphery of the ring conveyor chain plate. During the subsequent operation of the chain conveyor belt, compressed air is blown downward through the cleaning air knives to blow small particles of impurities stuck in the ventilation holes of the ring conveyor chain plate downward to the bottom of the drying box, thereby unblocking the ventilation holes of the ring conveyor chain plate and reducing the situation where the ventilation effect of the ring conveyor chain plate is affected by the blockage of the ventilation holes.

[0034] The soybeans transported on the chain conveyor 2 are heated by the heating assembly, and at the same time, the fan at the outlet pipe 12 draws the external air into the drying box 1 through the air inlet pipe 11 at the bottom of the drying box 1, and discharges it through the outlet pipe 12 at the top of the drying box 1, so as to form an upward airflow in the drying box 1; the moisture generated by the heated soybeans is taken out of the outlet pipe 12 by the upward airflow, so as to achieve the drying process of the soybeans, and the dried soybeans are transported to the output end by the chain conveyor 2 and discharged through the discharge pipe 14. At the same time, during the conveyance of the soybeans by the chain conveyor 2, the small particle impurities carried in the soybeans can fall into the bottom of the drying box 1 through the ventilation holes 211 on the annular conveying chain plate 21.

[0035] A collection hopper 15 is also connected to the bottom of the drying box 1, and a screw conveyor 16 is connected to the bottom of the collection hopper 15.

A plurality of impact rods 131 are also horizontally supported in the feed pipe 13. In the present embodiment, the impact rods 131 are all made of stainless steel bars; the upper and lower impact rods 131 are staggered. Through the arrangement of a plurality of impact rods 131, the subsequent soybeans can collide with a plurality of impact rods 131 after falling into the air inlet pipe 11, and the impact rods 131 are used to separate small particles of impurities such as broken beans adhering to the surface of the soybeans, so that the subsequent small particles of impurities can better fall into the bottom of the drying box 1 through the ventilation holes 211 on the annular conveying chain plate 21 during the transportation of the chain conveyor 2, thereby reducing the situation where impurities such as broken beans follow the soybeans out of the discharge pipe 14.

[0038] One end of the impact rod 131 is fixed to the side wall of the feed pipe 13 by bolts. An inspection port is also provided on the outside of the feed pipe 13, and a sealing cover 132 for sealing the inspection port is also provided on the feed pipe 13, and the sealing cover 132 is fixed to the feed pipe 13 by a plurality of bolts.

[0039] A baffle plate 17 is also obliquely supported at one end of the inner cavity of the drying box 1 close to the feed pipe 13. The baffle plate 17 is located on one side of the connection between the feed pipe 13 and the drying box 1. The oblique upper end of the baffle plate 17 is connected to the cavity wall at the end of the drying box 1, and the oblique lower end of the baffle plate 17 extends to above the input end of the chain conveyor 2. The baffle plate 17 is used to block the space between the input end of the chain conveyor 2 and the cavity wall at the end of the drying box 1 to reduce the subsequent soybeans that fall through the feed pipe 13 and fall directly into the bottom of the drying box 1 through the gap between the input end of the chain conveyor and the end of the drying box 1.

[0040] Reference Figure 2and Figure 4 The discharge pipe 14 is arranged vertically downward, and the output end of the chain conveyor 2 extends to the top of the discharge pipe 14, so as to realize the connection between the output end of the chain conveyor 2 and the discharge pipe 14; so that the soybeans subsequently transported to the output end via the chain conveyor 2 can be directly discharged through the discharge pipe 14.

[0041] The inner cavity of the drying box 1 is also provided with a scraper air knife 18, which is located at the bottom of the input end of the chain conveyor 2; the scraper air knife 18 is fixed in the drying box 1 through a bracket; the air outlet of the scraper air knife 18 is arranged toward the annular conveying chain plate 21 of the chain conveyor 2; the scraper air knife 18 is connected to the air source; through the above arrangement, during the subsequent operation of the chain conveyor 2, the scraper air knife 18 continuously blows compressed air toward the annular conveying chain plate 21 at the output end of the chain conveyor 2, so as to blow off the soybeans stuck on the ventilation holes 211 of the annular conveying chain plate 21 due to their volume, thereby reducing the situation in which the air permeability of the annular conveying chain plate 21 is affected due to the soybeans being stuck at the ventilation holes 211.

[0042] A guide plate 19 is also supported at one end of the inner cavity of the drying box 1 near the discharge pipe 14. The guide plate 19 is connected to the inner side wall of the drying box 1. The guide plate 19 is tilted, and the tilted upper end of the guide plate 19 extends to the bottom of the scraping air knife 18, and the tilted lower end of the guide plate 19 extends into the discharge pipe 14.

By arranging the nozzle 31 on the heating pipe 3 vertically upward, on the one hand, it is beneficial for the subsequent hot air and steam to directly contact the soybeans on the annular conveying chain plate 21, and on the other hand, it is beneficial for the hot air or steam to flow in the same direction as the air in the drying box 1, thereby reducing the collision between the hot air or steam and the air flowing from bottom to top in the drying box 1, resulting in air flow turbulence and affecting the soybean drying effect.

Through the above arrangement, during the subsequent operation of the chain plate conveyor 2, the cleaning air knives 5 continuously blow compressed air downward, and the compressed air blown by the cleaning air knives 5 is used to blow small particles of impurities such as broken beans that are blocked in the ventilation holes 211 of the annular conveying chain plate 21 downward from the ventilation holes 211, so as to achieve the dredging of the ventilation holes 211 and reduce the situation where the ventilation holes 211 of the chain plate conveyor 2 are blocked and affect the ventilation effect.

[0046] The working principle of the embodiment of the present application is that after the soybeans to be dried are conveyed to the chain conveyor 2 through the feed pipe 13, the chain conveyor 2 conveys the soybeans from the input end to the conveying end. During this period, hot air is continuously introduced into the heating pipe 3 by the hot air source through the connecting pipe 30, and the hot air is sprayed upward through the nozzle 31 on the heating pipe 3 and contacts with the soybeans through the ventilation holes 211 on the annular conveying chain plate 21 of the chain conveyor 2 to heat the soybeans; at the same time, the outside air is drawn into the drying box 1 through the air inlet pipe 11 by the fan at the air outlet pipe 12 and discharged through the air outlet pipe 12 to form an ascending airflow in the drying box 1, and the moisture generated by the heated soybeans is entrained and brought out to the air outlet pipe 12 by the ascending airflow, so as to realize the drying of the soybeans. After the dried soybeans are conveyed to the output end via the chain conveyor 2, they are automatically discharged through the discharge pipe 14, effectively improving the convenience of soybean drying processing.
