Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a drying equipment with monitoring function. Background Technology

[0002] In the soybean processing industry, soybean drying is a crucial step, and small processing plants and individual farmers face traditional challenges in this area. Traditional soybean drying equipment has revealed numerous problems that urgently need to be addressed in practical applications.

[0003] On the one hand, most existing small-scale drying devices lack effective impurity handling mechanisms. During the soybean drying process, hot airflow can cause impurities in the soybeans to become airborne. If these impurities are directly released into the air, they will not only cause environmental pollution but may also harm the health of operators. Moreover, complex filtration equipment is often required to purify the exhaust gas, which undoubtedly increases equipment costs and processing steps, and reduces overall processing efficiency.

[0004] On the other hand, different processing methods for soybean products require different levels of soybean drying, and the methods for monitoring soybean drying quality are relatively outdated. Typically, the determination of whether soybeans are dried properly relies solely on the operator's experience or simple sampling tests, making it difficult to achieve accurate and real-time monitoring of drying quality. This approach easily leads to over-drying or under-drying of soybeans, affecting their shelf life and the quality of the final product, and failing to ensure product consistency and high quality.

[0005] In conclusion, developing a new type of drying device that can effectively remove impurities generated during the drying process and has precise monitoring capabilities to ensure the quality of soybean drying has become an important issue that needs to be addressed in small factories and household farming. Summary of the Invention

[0015] Preferably, the gravel particle size is larger than the mesh diameter.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention uses the suction of a hot air blower to create negative pressure inside the purification chamber. Gas from the drying chamber enters the purification chamber through a first air pipe, where the gaps between the sand grains filter out flying impurities. The hot air blower then heats the gas and discharges it into the drying chamber through a third air pipe, achieving hot air circulation for drying soybeans. A motor drives the mesh drum to rotate, and a paddle lifts the sand grains. As the sand grains fall, the space increases, allowing impurities mixed in with the sand grains to fall down. The collection bucket collects the impurities, achieving impurity removal and preventing impurities from spreading into the air and polluting the environment. This invention not only dries soybeans but also directly removes impurities generated during the drying process, thus avoiding subsequent filtration operations and improving processing efficiency.

[0018] 2. This invention increases the weight of the bracket, and under the transmission of the rack and pinion and the first gear, the pressure of the piston squeezing the hydraulic oil gradually increases, causing the Bourdon tube to deform more and more. With the cooperation of the connecting rod and the sector gear, the second gear drives the pointer to rotate clockwise. The weight of the soybeans after drying is calculated based on the weight of the soybeans. The slider is moved so that the proximity switch points to the scale of the weight of the soybeans after drying on the dial. Under the push of the spring, the ball is inserted into the corresponding positioning blind hole to position the slider. As the moisture of the soybeans decreases, the weight gradually decreases, the deformation of the Bourdon tube decreases, and the pointer rotates counterclockwise. When the pointer blocks the proximity switch, the alarm light illuminates and sounds an alarm. It has a soybean drying monitoring function, allowing soybeans to be stored in the best drying state, ensuring the consistency and high quality of the final product. It can dry soybeans to different degrees according to different soybean product processing needs.

[0019] 3. This invention can also be applied to the drying of chemical products. When drying materials in small chemical plants, the purification mechanism can filter impurities and avoid pollution. The hot air circulation achieves efficient drying, eliminating the need for subsequent waste gas purification processes and improving production efficiency. Based on the strict requirements of chemical products for material dryness, the drying quality monitoring mechanism can accurately control the drying process, set standards according to product requirements, and alarm when the standards are met, reducing the defect rate and increasing economic benefits. The device has a compact structure, is easy to install and maintain, has low energy consumption, and is highly versatile. It can be adapted to the drying of various chemical materials, improving equipment utilization. Attached Figure Description

The air outlet of the hot air blower 7 is connected to the bottom of the gas diffuser hood 4 through the third air pipe 9. The back of the drying box 1 is equipped with a solar panel 10 through a bracket. The bracket is an adjustable bracket that can adjust the angle and direction of the solar panel 10 to facilitate the absorption of sunlight by the solar panel 10. The solar panel 10 can provide power to the device, making it more convenient for small factories and farmers to use.

[0031] As a preferred embodiment, the drying quality monitoring mechanism 3 further includes a monitoring box 31 fixedly connected to the left end of the upper surface of the drying chamber 1. An alarm light 32 is installed on the front of the monitoring box 31, illuminating when powered on to alert workers that the soybean drying is complete. A first rotating shaft 33, capable of rotating around its own axis, is mounted at the center of the inner cavity of the monitoring box 31 via a bearing. A first gear 34 is mounted on the outer wall of the first rotating shaft 33. A weight detection component 35 is installed at the left end of the upper surface of the monitoring box 31, and a weight detection component 35 is vertically mounted at the right end of the lower surface of the monitoring box 31. The limiting cylinder 36 has a limiting rod 37 that can slide up and down inserted into its inner cavity. A bracket 38 is installed at the bottom of the limiting rod 37. The inner side of the bracket 38 is used to store and place a tray for soybeans. A rack 39 is installed at the top of the limiting rod 37 and the bottom of the weight detection component 35. The rack 39 is meshed with the first gear 34. The outer wall of the limiting rod 37 is rectangular to prevent the rack 39 from rotating. The two racks 39 are distributed on both sides of the first gear 34, and under the transmission of the first gear 34, the two racks 39 can move in opposite directions.

[0032] As a preferred embodiment, the weight detection assembly 35 further includes a piston cylinder 351 vertically mounted on the left end of the upper surface of the monitoring box 31. A piston 352 capable of sliding up and down is inserted into the inner cavity of the piston cylinder 351. The bottom of the piston 352 is connected to a rack 39. The inner cavity of the piston cylinder 351 is filled with hydraulic oil 353. Under the gravity of the bracket 38 and the limiting rod 37, the right rack 39 descends, causing the left rack 39 to drive the piston 352 to squeeze the hydraulic oil 353 upward, increasing the pressure of the hydraulic oil 353. A dial indicator 354 is installed on the top of the outer wall of the piston cylinder 351. A slide rail 355 is provided. Positioning blind holes 356 are equidistantly spaced along the outer edge of the front of the watch case 354. A dial 357 is installed at the front end of the inner cavity of the watch case 354, and a weight unit is set on the dial 357. A second rotating shaft 358, capable of rotating around its own axis, is installed at the center of the inner cavity of the watch case 354 via a bearing. A pointer 359 and a second gear 3510 are respectively installed at the front and rear ends of the second rotating shaft 358. When the right rack 39 only bears the weight of the bracket 38 and the limiting rod 37, the pointer 359 points to the zero point on the dial 357, achieving the purpose of zeroing. The piston cylinder 351 has a top edge on the left side wall. One end of the Bourdon tube 3511 is connected to a sector gear 3512, which meshes with the second gear 3510, via a pin to the rear side of the inner cavity of the dial 357. The other end of the Bourdon tube 3511 is connected to one end of a connecting rod 3513 via a pin. The other end of the connecting rod 3513 is connected to the right end of the sector gear 3512 via a pin. The Bourdon tube 3511 gradually deforms due to the increased pressure of the hydraulic oil 353, which in turn causes the connecting rod 3513 to pull the sector gear 3512 to rotate counterclockwise. This causes the second gear 3510 to drive the pointer 359 to rotate clockwise. The pointer 359 points to the dial 357. The scale on 57 indicates the current weight of the soybeans on the bracket 38. A slider 3514 is slidably connected to the inner cavity of the slide rail 355. A proximity switch 3515, which is electrically connected to the alarm light 32, is installed at the center of the slider 3514. A spring 3516 and a ball bearing 3517 are inserted from the inside to the outside of the inner side of the inner cavity of the slider 3514. Under the elastic force of the spring 3516, the ball bearing 3517 is inserted into the inner cavity of the positioning blind hole 356 to position the slider 3514. The positioning blind hole 356 corresponds one-to-one with the scale on the dial 357, and the position of the proximity switch 3515 can be adjusted according to the scale on the dial 357.

[0033] As a preferred embodiment, the purification mechanism 5 further includes a purification box 51 fixedly connected to the top of the right side wall of the drying box 1. The bottom of the right side wall of the purification box 51 is connected to the end of the second air pipe 8. A first gas collecting hood 52 and a second gas collecting hood 53 are respectively installed at the top and bottom of the purification box 51. The top of the first gas collecting hood 52 is connected to the end of the first air pipe 6. A collection bucket 54 is screwed to the bottom of the second gas collecting hood 53. Impurities are collected through the collection bucket 54. A filter assembly 55 is horizontally installed on the top of the right side wall of the purification box 51.

[0034] As a preferred embodiment, the filter assembly 55 further includes a motor 551 installed on the top of the right side wall of the purification box 51. One end of the mesh cylinder 552 is installed at the output end of the motor 551. The other end of the mesh cylinder 552 is installed on the left inner wall of the purification box 51 via a bearing. The outer wall of the mesh cylinder 552 is infinitely close to the front and rear inner walls of the purification box 51. Several paddles 553 are installed equidistantly along the circumference from left to right on the inner wall of the mesh cylinder 552. The inner cavity of the mesh cylinder 552 is filled with gravel 554, which filters impurities through the gaps between the gravel 554. The particle size of the gravel 554 is larger than the aperture of the mesh cylinder 552 to prevent the gravel 554 from escaping from the mesh cylinder 552.

[0035] Working principle:

[0036] Step 1: Place the tray containing soybeans on the rack 38, close the door 2, and the gas in the purification box 51 is absorbed by the suction of the hot air blower 7 and heated. The gas is discharged from bottom to top into the drying box 1 through the gas diffuser 4. The hot air flows in the drying box 1 to dry the soybeans and remove the moisture from the soybeans.

[0037] Step two: Gas enters the purification chamber 51 through the first gas pipe 6. Impurities raised in the drying chamber 1 pass through the mesh of the screen cylinder 552 and the gaps between the sand and gravel 554 to filter the impurities. The impurities are blocked by the sand and gravel 554. After purification, the gas is heated by the hot air blower 7 to remove impurities and prevent them from spreading into the air and polluting the environment. This not only dries soybeans but also removes impurities generated during the drying process, thus avoiding subsequent filtration operations and improving processing efficiency.

[0038] When it is necessary to remove impurities from the gravel 554, the motor 551 drives the screen cylinder 552 to rotate. Under the action of the paddle 553, the gravel 554 rises a certain distance and then falls, causing the gravel 554 to roll in the screen cylinder 552, widening the gap between the gravel 554 in the screen cylinder 552. Impurities can fall out from the gaps in the screen cylinder 552 and important impurities are collected through the collection bucket 54.

[0039] Step 3: Before drying, the weight of the soybeans causes the limit rod 37 to drive the rack 39 to descend. Under the transmission of the rack 39 and the first gear 34, the piston 352 moves upward and squeezes the hydraulic oil 353. The pressure of the Bourdon tube 3511 increases, causing the cross-section to become rounded and undergo elastic deformation. As a result, the bending degree of the Bourdon tube 3511 decreases. The Bourdon tube 3511 pulls the sector gear 3512 to rotate counterclockwise through the connecting rod 3513, which in turn causes the second gear 3510 to drive the pointer 359 to rotate clockwise. The scale on the dial 357 pointed to by the pointer 359 is the weight of the soybeans. The weight of the soybeans after drying is calculated based on the soybean water content. The sliding slider 3514 moves on the slide rail 355 until it approaches the switch 3515 at the soybean drying scale on the dial 357. Under the elastic force of the spring 3516, the ball 3517 is pushed to insert into the corresponding positioning blind hole 356 to position the slider 3514 after moving.

[0040] As the moisture content of the soybeans decreases, their weight gradually decreases. The pressure of the rack 39 pressing the piston 352 also gradually decreases, which in turn causes the hydraulic oil 353 pressure to gradually decrease. The Bourdon tube 3511 gradually returns to its original state. At the same time, the sector gear 3512 and the second gear 3510 drive the pointer 359 to rotate counterclockwise. When the pointer 359 blocks the proximity switch 3515, the proximity switch 3515 energizes the alarm light 32 to illuminate, reminding the staff that the soybeans have been dried and improving the quality of soybean drying.
