Description

Technical Field

[0001] This invention relates to the field of direct contact gas heat exchange technology, specifically to an energy-saving food drying and processing equipment. Background Technology

[0002] Energy-saving food drying and processing equipment is a type of drying equipment that recovers waste heat generated during the drying process through a heat exchange device with a heat exchange medium, converting it into reusable useful heat energy to replace or reduce external primary energy input, thereby achieving the goal of significantly reducing the overall energy consumption of the system.

[0003] Patent publication number CN216845572U relates to a multi-layer tunnel mesh belt dryer for food drying. It solves the problems of low efficiency, high energy consumption, and uneven drying associated with traditional food powder drying methods that often use old-fashioned tunnel kilns. The multi-layer tunnel mesh belt dryer includes a drying chamber and several horizontally arranged drying conveyor belts inside the chamber. A lifting frame is located on one side of the drying chamber, and a discharge conveyor belt is located on the other side. An infeed conveyor belt is located inside the lifting frame, with both sides of the infeed conveyor belt slidably connected to the inside of the lifting frame. This patent has a reasonable structure, is easy to operate, and facilitates the conveying of materials to drying conveyor belts of different heights, greatly improving the convenience of drying. Furthermore, using a multi-layer tunnel mesh belt dryer significantly improves the uniformity and quality of drying.

[0004] The above-mentioned technical solution uses a feeding conveyor belt inside the lifting frame, with both sides of the feeding conveyor belt slidingly connected to the inside of the lifting frame. This facilitates the conveying of materials to drying conveyor belts of different heights, greatly improving the convenience of drying. At the same time, the use of a multi-layer tunnel mesh belt dryer to dry materials can greatly improve the uniformity and quality of drying. However, the equipment has a prominent drawback of high energy consumption during operation. First, the hot air system of the equipment is mostly open or semi-open circulation, and the high-temperature exhaust gas after drying is directly discharged to the outside. A large amount of waste heat carried in the exhaust gas is not recovered and utilized, resulting in serious energy waste and a large amount of unnecessary energy consumption.

[0010] The auxiliary energy-saving device also includes a running trigger device installed on the drying shaft cylinder. The running trigger device includes a running lifting mechanism installed on the drying shaft cylinder and a drain outlet anti-clogging mechanism installed on the running lifting mechanism. The operation triggering device is used to trigger and move the component to the drying area when the equipment is running; The lifting mechanism is used to lower the components to the drying area and process them during equipment operation; The drain outlet anti-clogging mechanism is used to clean the drain outlet and prevent blockage from affecting the drainage function.

[0011] The operating lifting mechanism includes a threaded ring on the drying shaft cylinder, a sliding ring mounted on the threaded ring, a connecting ring mounted on the collar, a spring rod mounted on the connecting ring, and a fixed connecting plate mounted on the fixed rod; The connecting ring is connected to the sliding ring, the spring rod is connected to the heat exchange energy-saving drying cylinder, and the threaded ring is connected to the sliding ring by a thread.

[0012] The drain outlet anti-clogging mechanism includes an anti-clogging rod installed on the fixed connecting plate and a telescopic cleaning rod installed on the anti-clogging rod; The free end surface of the telescopic cleaning rod is configured as an arc surface.

[0013] The auxiliary energy-saving device also includes a filter element maintenance device installed on the fixed connecting plate.

[0014] The filter cleaning mechanism includes a rotating rod mounted on the fixed connecting plate, a cleaning roller mounted on the rotating rod, and a contact wheel mounted on the rotating rod; The surface of the cleaning roller is made of bristles, and the contact wheel is made of a flexible material.

[0015] The striking vibration mechanism includes an eccentric wheel mounted on the rotating rod, a force-bearing frame mounted on the fixed connecting plate, a striking frame mounted on the force-bearing frame, a striking plate mounted on the striking frame, a spring rod mounted on the fixed connecting plate, and a collection tray mounted on the drying cylinder. The force-bearing frame has an arc surface three on its surface, the striking frame is connected to the force-bearing frame, and the spring rod three is connected to the striking frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, hot air enters the heat exchange circulating air box through the air inlet duct. At the same time, the heat exchange circulating air box uses its special shape to uniformly guide the hot air, improving the uniformity of drying and the consistency of material drying. This avoids over-drying or under-drying caused by local air volume differences. The exhaust component guides the waste heat airflow to the open heat recovery component, where it flows around the outer surface of the fixed heat exchange duct as a large fluid outside the pipe and washes the outer surface of the fixed heat exchange duct. Meanwhile, fresh air from outside enters the internal flow channel of the fixed heat exchange duct through the air inlet duct. During the flow inside the pipe, it absorbs the heat of the waste heat outside the pipe through the duct wall, thus completing the preheating before entering the heat exchange circulating air box. This process achieves efficient indirect heat exchange between waste heat outside the pipe and fresh air inside the pipe, significantly improving the overall thermal efficiency of the machine. Furthermore, because the drying shaft contains drying particles, these particles adsorb the moisture generated during the dehydration process inside the heat exchange energy-saving drying cylinder, preventing moisture condensation from affecting normal equipment operation. The rotation of the drying shaft also agitates the drying particles, further increasing the contact area with the moisture inside the heat exchange energy-saving drying cylinder, thus improving the drying effect and reducing energy consumption. This lowers long-term energy costs and operating power consumption. The rotating fixed rod drives the shovel plate to rotate, which contacts and scrapes off materials at or attached to the edge, guiding them towards the center. This prevents materials from moving towards the edge under the agitation of the mixing plate until they leave their running trajectory. Simultaneously, continuous pushing prevents dehydrated materials from sticking to the equipment surface, thus affecting subsequent feeding or cleaning.

[0017] 2. In this invention, the connecting ring moves under the action of the sliding ring, causing the collar to move downward. At this time, the filter disc is lifted by the elastic potential energy of the spring rod, making it easy for workers to remove it for thorough cleaning. This effectively reduces the labor intensity and time cost of maintenance. The anti-clogging rod rotates, causing the telescopic cleaning rod to rotate. The telescopic cleaning rod rotates to clean and prevent clogging of the drain outlet on the surface of the discharge disc, avoiding water accumulation due to blockage of the drain outlet, which would affect the quality of the dried product. The telescopic cleaning rod can rotate, thus passing smoothly without rigid jamming and continuing to rotate, ensuring the continuity and smoothness of the cleaning action.

[0018] 3. In this invention, the contact wheel rotates to drive the rotating rod, which in turn drives the cleaning roller to rotate. The cleaning roller then drives the brush to rotate, thoroughly cleaning the bottom of the filter disc. This effectively maintains the filter disc's water filtration and air permeability. The three free ends of the spring rod move upward, which in turn drives the striking plate to move upward through the striking frame, striking the bottom of the filter disc and generating vibration. This further improves the cleaning effect on the bottom of the filter disc, while preventing stubborn impurities from being difficult for the cleaning roller to remove, thus avoiding equipment operation obstruction. It also improves the thoroughness of cleaning, prevents increased air resistance or local blockage caused by the accumulation of impurities, and ensures the equipment's continuous and efficient drying performance and smooth operation.

[0021] 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.

[0022] Please see Figures 1-4 One embodiment of the present invention is as follows: an energy-saving food drying and processing equipment includes a heat exchange energy-saving drying cylinder 1, and the energy-saving food drying and processing equipment further includes: Heat exchange circulating air box 11; An auxiliary energy-saving device for assisting and reducing equipment energy consumption includes a heat exchange energy-saving mechanism installed on the heat exchange energy-saving drying cylinder 1 and a stirring and feeding mechanism installed on the heat exchange energy-saving mechanism. Among them, the heat exchange energy-saving mechanism is used to reduce equipment energy consumption through heat exchange; The mixing and feeding mechanism is used to mix and feed materials. The heat exchange energy-saving mechanism includes a heat exchange circulating air box 11 installed on the heat exchange energy-saving drying cylinder 1 for heat and mass exchange between hot air and wet materials, an air inlet duct 12 installed on the heat exchange circulating air box 11, an open heat recovery component 13 installed on the air inlet duct 12 for performing heat recovery and heating, a fixed heat exchange duct 14 installed on the open heat recovery component 13 for preheating fresh air and whose internal flow channel is only for fresh air to pass through, and an exhaust component 15 installed on the heat exchange energy-saving drying cylinder 1.

[0023] The heat exchange energy-saving mechanism also includes a drying shaft cylinder 21 installed on the heat exchange energy-saving drying cylinder 1, a feeding tray 22 installed on the drying shaft cylinder 21, a filter tray 23 installed on the feeding tray 22, a gear 1 24 installed on the drying shaft cylinder 21, a gear 25 installed on the heat exchange energy-saving drying cylinder 1, and a drive motor 26 installed on the heat exchange energy-saving drying cylinder 1.

[0024] The mixing and feeding mechanism includes a collar 31 mounted on the drying shaft cylinder 21, a fixing rod 32 mounted on the collar 31, a mixing plate 33 mounted on the fixing rod 32, a scraper plate 34 mounted on the fixing rod 32, a fixing frame 35 mounted on the feeding tray 22, and a spring rod 36 mounted on the fixing frame 35.

[0025] The surface of the heat exchange circulating air box 11 is provided with circulation holes. Gear 1 24 and gear 2 25 mesh with each other. The output end of the drive motor 26 is connected to gear 2 25. The angle of the stirring plate 33 is set to an inclined angle. The shovel plate 34 contacts the discharge plate 22. The surface of the shovel plate 34 is set to an arc surface. The spring rod 1 36 is connected to the filter plate 23. The surface of the filter plate 23 is provided with water filtering holes. The surface of the discharge plate 22 is provided with a drain outlet. The interior of the drying shaft cylinder 21 is provided with a hollow chamber. The surface of the hollow chamber is provided with a drying circulation hole. The hollow chamber is provided with dried particles. The hollow chamber, the drying circulation hole and the drying shaft cylinder 21 are interconnected. The circulation hole is used to guide the hot air flow. The angle of the stirring plate 33 is set to an inclined angle to guide the direction of material stirring and pushing. The arc surface is used to assist in scraping the edge material. The water filter hole is used to filter out the dewatering material during the drying process. The drain outlet is used to discharge the dewatering material during the drying process.

[0026] In this embodiment, during operation: the operator places the material to be dried on the feeding tray 22, starts the equipment, and draws in outside natural air through the air inlet duct 12, heats it through the open heat recovery component 13, and then delivers it through the air inlet duct 12 to the heat exchange energy-saving drying cylinder 1. At this time, the hot air enters the heat exchange circulating air box 11 through the air inlet duct 12. Simultaneously, the heat exchange circulating air box 11 uses its special shape to uniformly guide the hot air, improving the uniformity of drying and the consistency of material drying, avoiding over-drying or under-drying caused by local air volume differences. When the hot air passes through the material placement area, it is discharged through the exhaust component 15 at the other end. The exhaust component 15 guides the drying waste heat airflow into the open heat recovery component 13, where it flows around the pipe as a large fluid outside the pipe and washes the outer surface of the fixed heat exchange duct 14. At the same time, outside fresh air enters the internal flow channel of the fixed heat exchange duct 14 through the air inlet duct 12. During the flow inside the pipe, it absorbs the heat of the waste heat outside the pipe through the duct wall, thus completing the preheating before entering the heat exchange circulating air box 11. This process achieves efficient indirect heat exchange between waste heat outside the pipe and fresh air inside the pipe, significantly improving the overall thermal efficiency. At this point, the exhaust component 15 enables efficient recovery and reuse of waste heat, further improving the overall thermal efficiency and reducing long-term energy costs and operating power consumption. Before drying the material, the drive motor 26 needs to be started. The output of the drive motor 26 rotates, driving gear 25 to rotate. Because gear 25 meshes with gear 1 24, the rotation of gear 25 contacts and meshes with gear 1 24, causing gear 1 24 to rotate. This rotation of gear 1 24 then drives the drying shaft cylinder 21 to rotate, which in turn drives the collar 31 to rotate. The collar 31 then drives the fixed rod 32 to rotate, which in turn drives the stirring plate 33 to rotate, uniformly pushing and stirring the material. Furthermore, because the drying shaft cylinder 21 contains drying particles, the drying shaft cylinder 21... The dried particles adsorb the moisture generated during the dehydration process inside the heat exchange energy-saving drying cylinder 1, preventing the internal moisture from condensing and affecting the normal operation of the equipment. The rotation of the drying shaft cylinder 21 agitates the dried particles inside, further increasing the contact area with the moisture inside the heat exchange energy-saving drying cylinder 1, thereby improving the drying effect and reducing the energy consumption of the equipment. At the same time, the stirring plates 33 at the other end are set in opposite directions and are evenly distributed. The rotation of the stirring plates 33 continuously pushes and stirs the material. Meanwhile, the rotation of the fixed rod 32 drives the shovel plate 34 to rotate. The shovel plate 34 rotates and contacts and scrapes off the material at or attached to the edge and guides it inward, preventing the material from moving to the edge under the stirring action of the stirring plate 33 until it leaves its running trajectory. At the same time, the continuous pushing prevents the dehydrated material from sticking to the surface of the equipment, thus affecting subsequent feeding or cleaning.

[0027] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the auxiliary energy-saving device further includes a running trigger device installed on the drying shaft cylinder 21. The running trigger device includes a running lifting mechanism installed on the drying shaft cylinder 21 and a drain outlet anti-blocking mechanism installed on the running lifting mechanism. Among them, the operation triggering device is used to trigger and drive the component to move to the drying area when the equipment is running; The lifting mechanism is used to lower components to the drying area and process them during equipment operation; The drain outlet anti-clogging mechanism is used to clean the drain outlet and prevent blockage from affecting the drainage function.

[0028] The operating lifting mechanism includes a threaded ring 41 on the drying shaft cylinder 21, a sliding ring 42 mounted on the threaded ring 41, a connecting ring 43 mounted on the collar 31, a spring rod 44 mounted on the connecting ring 43, and a fixed connecting plate 45 mounted on the fixed rod 32. Among them, the connecting ring 43 is connected to the sliding ring 42, the spring rod 44 is connected to the heat exchange energy-saving drying cylinder 1, and the threaded ring 41 and the sliding ring 42 are connected by threads.

[0029] The drain outlet anti-clogging mechanism includes an anti-clogging rod 51 installed on the fixed connecting plate 45 and a telescopic cleaning rod 52 installed on the anti-clogging rod 51; Among them, the free end surface of the telescopic cleaning rod 52 is set as arc surface II; The second curved surface is used to avoid operational stagnation.

[0030] In this embodiment, when the drying shaft cylinder 21 rotates under the action of the drive motor 26, the rotation of the drying shaft cylinder 21 drives the threaded ring 41 to rotate. Since the threaded ring 41 and the sliding ring 42 are connected by threads, the rotation of the threaded ring 41 drives the sliding ring 42 to move downward. The downward movement of the sliding ring 42 drives the connecting ring 43 to move. The movement of the connecting ring 43 under the action of the sliding ring 42 drives the collar 31 to move downward. At this time, the filter disc 23 is lifted up under the elastic potential energy of the spring rod 36, making it easy for the staff to remove it for detailed cleaning, effectively reducing the labor intensity and time cost of maintenance. The downward movement of the collar 31 drives the fixed rod 32 to move, and at the same time, the movement of the fixed rod 32 drives the shovel plate. 34. Move the downward pressing filter disc 23 until it locks. When the fixed rod 32 rotates, it drives the fixed connecting plate 45 to rotate. The fixed connecting plate 45 rotates, which drives the anti-blocking rod 51 to rotate. The anti-blocking rod 51 rotates, which drives the telescopic cleaning rod 52 to rotate. At this time, the telescopic cleaning rod 52 rotates to clean and prevent blockage of the drain outlet on the surface of the discharge disc 22, thus avoiding water accumulation due to blockage of the drain outlet and affecting the quality of the dried product. When the telescopic cleaning rod 52 continues to rotate, the free end surface of the telescopic cleaning rod 52 contacts and retracts under the action of the discharge disc 22. At this time, the telescopic cleaning rod 52 can rotate, so as to pass smoothly without rigid jamming and continue to rotate, ensuring the continuity and smoothness of the cleaning action.

[0031] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the auxiliary energy-saving device further includes a filter element maintenance device installed on the fixed connecting plate 45. The filter element maintenance device includes a filter element cleaning mechanism installed on the fixed connecting plate 45 and a knocking vibration mechanism installed on the filter element cleaning mechanism. Among them, the filter element maintenance device is used to maintain the filter element and assist its normal operation; The filter element cleaning mechanism is used to clean the filter elements and prevent clogging; The tapping and vibration mechanism is used to tap and vibrate the water filter components to improve the cleaning effect.

[0032] The filter cleaning mechanism includes a rotating rod 61 mounted on a fixed connecting plate 45, a cleaning roller 62 mounted on the rotating rod 61, and a contact wheel 63 mounted on the rotating rod 61. The surface of the cleaning roller 62 is made of bristles, and the material of the contact wheel 63 is made of a flexible material. The brush bristles are used to brush and clean the bottom of the filter disc 23. The contact wheel 63 is made of a flexible material to avoid directly squeezing the filter disc 23 and causing it to float, thus affecting the normal operation of the equipment.

[0033] The striking vibration mechanism includes an eccentric wheel 71 mounted on a rotating rod 61, a force-bearing frame 72 mounted on a fixed connecting plate 45, a striking frame 73 mounted on the force-bearing frame 72, a striking plate 74 mounted on the striking frame 73, a spring rod 75 mounted on the fixed connecting plate 45, and a collection tray 76 mounted on the drying shaft cylinder 21. Among them, the surface of the force-bearing frame 72 is provided with an arc surface three, the striking frame 73 is connected to the force-bearing frame 72, and the spring rod three 75 is connected to the striking frame 73; The arc surface 3 is used to assist the eccentric wheel 71 in bearing force.

[0034] In this embodiment, during operation: when the fixed connecting plate 45 rotates under the action of the fixed rod 32, the fixed connecting plate 45 rotates around the drying shaft cylinder 21, driving the rotating rod 61 to rotate. The rotating rod 61 rotates, driving the cleaning roller 62 to rotate. The cleaning roller 62 performs preliminary cleaning on the bottom of the filter disc 23. At the same time, the rotating rod 61 drives the contact wheel 63 to rotate. At this time, because the filter disc 23 moves downward under the action of the scraper plate 34 and contacts the contact wheel 63, the contact wheel 63 rotates under the contact action on the surface of the filter disc 23. The rotation of the contact wheel 63 drives the rotating rod 61 to rotate, which in turn drives the cleaning roller 62 to rotate. The rotation of the cleaning roller 62 drives the bristles to rotate, performing a thorough cleaning on the bottom of the filter disc 23, effectively maintaining the water filtration and air permeability of the filter disc 23. At the same time, the rotation of the rotating rod 61 drives the eccentric wheel 71 to rotate, and the eccentric wheel 71 rotates to contact and squeeze the force frame 72. As the filter disc 23 moves downwards, the force-bearing frame 72 moves, causing the striking frame 73 to move downwards. The striking frame 73 then compresses the spring rod 75, causing it to move. Subsequently, the eccentric wheel 71 continues to rotate under the action of the rotating rod 61. When the spring rod 75 loses its compressive restraint, its deformation returns to its original state, and its free end moves upwards. This upward movement of the free end of the spring rod 75 drives the striking plate 74 to move upwards via the striking frame 73, striking and vibrating the bottom of the filter disc 23. This further improves the cleaning effect on the bottom of the filter disc 23, while preventing stubborn impurities from being difficult for the cleaning roller 62 to remove, thus avoiding equipment obstruction. It also improves the thoroughness of cleaning, preventing increased air resistance or local blockage caused by impurity accumulation, ensuring the continuous and efficient drying performance and smooth operation of the equipment. The cleaned impurities then fall into the collection tray 76 for centralized processing by the staff.
