A circulating grain water molecule evaporation device based on an air source heat pump

Abstract

The present invention relates to the field of drying, and particularly to a circulating grain water molecule evaporation device based on an air source heat pump. In existing grain water molecule evaporation devices, the accumulation of grains easily causes poor hot air circulation, reducing the drying efficiency; when many devices are heating, they only simply convey hot air, lacking a reasonable mechanism for hot air utilization and water vapor discharge, resulting in slow evaporation of water molecules inside the grains and unsatisfactory drying effects. A circulating grain water molecule evaporation device based on an air source heat pump includes a base; an evaporation cylinder is fixedly connected to the base, and a feed hopper is fixedly connected to the outer side of the upper part of the evaporation cylinder. Then the hot air enters the moisture extraction cover, and is then sucked away by the suction ring pipe and the exhaust pipe, thereby realizing the drying process of the grains. Moreover, the suction ring pipe will also penetrate into the interior of the grain pile between the evaporation cage and the moisture extraction cover through the rotating ring, the bent pipe, the fixed pipe and the tooth rake rod to extract the moisture therein and strengthen the drying effect.

Description

Technical Field

[0001] The present invention relates to the field of drying, and in particular to a circulating grain water molecule evaporation device based on an air source heat pump. Background Art

[0002] In the long chain of the grain industry, the drying link always occupies a crucial position. With the acceleration of the process of agricultural modernization, the demand for large-scale production and centralized storage of grains is increasing day by day, and the desire for efficient and high-quality drying technologies is becoming more and more urgent.

[0003] At present, few drying devices can ensure a good spreading state of grains during the drying process. The accumulation of grains is likely to cause poor hot air circulation and reduce the drying efficiency. When many devices are heating, they only simply convey hot air, lacking a reasonable mechanism for hot air utilization and water vapor discharge, resulting in slow evaporation of water molecules inside the grains and unsatisfactory drying effects. Summary of the Invention

[0004] In order to overcome the above-mentioned drawbacks, the present invention provides a circulating grain water molecule evaporation device based on an air source heat pump, which can enable full contact between hot air and grains, improve the drying efficiency, and at the same time can stir and disperse the grains, and can accelerate the extraction of moisture inside the grains to further improve the grain drying efficiency.

[0005] The technical solution is: a circulating grain water molecule evaporation device based on an air source heat pump, comprising a base, an evaporation cylinder fixedly connected to the base, a feed hopper fixedly connected to one side of the evaporation cylinder, a feed groove opened in the upper part of the evaporation cylinder, a blanking groove opened in the lower part of the evaporation cylinder, a rotary lifting assembly provided on the base, an evaporation assembly provided on the rotary lifting assembly, and a closing assembly provided in the upper part of the evaporation cylinder.

[0006] Further, the rotary lifting assembly includes a servo motor, a fixed screw fixedly connected to the output shaft of the servo motor, an octagonal nut threadedly connected to the middle of the fixed screw, a fixed sleeve fixedly connected to the outside of the octagonal nut, a fixed guide rod fixedly connected to the bottom of the fixed sleeve, and a transmission ring sleeved on the outside of the fixed sleeve.

[0007] Furthermore, the evaporation assembly includes an evaporation cage which is rotatably connected to the transmission ring. A hot gas space is formed inside the evaporation cage. A number of through holes are formed in the evaporation cage. A hot air pipe is fixedly connected to the bottom of the evaporation cage and is communicated with the bottom of the evaporation cage. A support ring is rotatably connected to the transmission ring. A moisture extraction cover is fixedly connected to the outside of the support ring. A moisture extraction space is formed inside the moisture extraction cover. A number of air extraction holes are formed in the lower part of the moisture extraction cover. An inclined ring is fixedly connected to the upper side of the moisture extraction cover. A sandwich layer is formed between the moisture extraction cover, the inclined ring and the evaporation cylinder. An air suction ring pipe is fixedly connected to the upper part of the moisture extraction cover and is communicated with the moisture extraction cover. An exhaust pipe is fixedly connected to the air suction ring pipe and passes through the inclined ring and the evaporation cylinder. A fixed pipe is fixedly connected to the middle of the transmission ring. A tooth rake rod is fixedly connected to the fixed pipe. The inside of the tooth rake rod is a cavity. A number of hollow holes are formed on both sides of the middle of the tooth rake rod. The aperture of the hollow holes on the tooth rake rod is smaller than the grain diameter. A rotating ring is slidably connected to one side of the moisture extraction cover close to the transmission ring. A bent pipe is fixedly connected between the fixed pipe and the rotating ring. The two ends of the bent pipe are respectively communicated with the fixed pipe and the rotating ring.

[0008] Furthermore, the apertures of the number of through holes on the evaporation cage are all smaller than the grain diameter.

[0009] Furthermore, the apertures of the number of air extraction holes formed in the lower part of the moisture extraction cover are all smaller than the grain diameter.

[0010] Furthermore, the closing assembly includes a vertical rod. Four vertical rods are fixedly connected to the outside of the inclined ring. Four fixed columns are fixedly connected to one side of the evaporation cylinder. A closing ring is supported between the four fixed columns. The closing ring is in contact with the evaporation cylinder. A compression spring is connected between the closing ring and the inner side of the top of the evaporation cylinder.

[0011] Furthermore, a stirring component is further included. The stirring component is arranged on the transmission ring and is used for turning the grains on the evaporation cage. The stirring component includes a fixing plate. Fixing plates are fixedly connected to both sides of the upper part of the transmission ring. An internal gear ring is fixedly connected between the two fixing plates. A rotating shaft is rotatably connected to the fixing kit. A small gear is fixedly connected to the upper part of the rotating shaft. The internal gear ring meshes with the small gear. Four support rods are fixedly connected to the fixing kit. Two limiting rings are fixedly connected between the four support rods. A sector gear ring is rotatably connected between the two limiting rings. The outer teeth of the sector gear ring mesh with the small gear.

[0012] Furthermore, a shaking component is further included. The shaking component is arranged on the fixing plate. An inclined block is fixedly connected to the lower part of the rotating shaft. A fixed ring is also fixedly connected between the two fixing plates. A number of circular columns are fixedly connected to the inner side of the fixed ring.

[0013] The beneficial effects of the present invention are as follows: 1. The thin layer of accommodation space constructed by the evaporation cage and the moisture extraction hood allows the grain to be spread out in an orderly manner, so that the subsequent influx of hot air can more smoothly and efficiently contact the grain, greatly improving the drying efficiency.

[0014] 2. Hot air continuously enters the evaporation cage and heats the grain through the numerous through holes on the evaporation cage, causing the grain temperature to gradually rise. During this process, the water molecules inside the grain continue to evaporate, forming hot air with water vapor. This hot air then enters the moisture extraction hood and is subsequently sucked away by the air intake ring and the exhaust pipe, thereby achieving the drying process of the grain. Not only that, the air intake ring will also penetrate into the grain pile between the evaporation cage and the moisture extraction hood through the rotating ring, curved pipe, fixed pipe and tooth rake rod to extract moisture from it and enhance the drying effect.

[0015] 3. The two fixed plates rotate forward, driving the transmission ring, fixed tube, rotating ring, bending tube and tooth rake rod to rotate forward together. The tooth rake rod rotates forward to stir the grain between the evaporation cage and the moisture extraction hood. The tooth rake rod is set in an inclined shape, and the tooth rake rod rotates forward to shovel the grain, thereby turning the grain, making the grain heated more evenly and significantly improving the heating effect. Not only that, there are tooth grooves at intervals on the tooth rake rod. During the forward rotation of the tooth rake rod, these tooth grooves will stagger and stir the grain, thereby further breaking up the grain pile, so that the grain can be fully exposed to the heat, accelerating the evaporation of internal moisture, and ensuring that the drying process is more efficient and thorough. Combined with the hollow holes on the intake ring tube, exhaust pipe and tooth rake rod, the tooth rake rod can also extract moisture from the grain while turning the grain, thereby greatly improving the drying efficiency of the grain.

[0016] 4. The inclined block intermittently drives the evaporation cage, moisture extraction hood, tooth rake rod and the grain between the evaporation cage and moisture extraction hood to rise and fall together, so that the grain is fully shaken out, the grain is heated more evenly, and the potential moisture inside is also accelerated to be discharged. The evaporation efficiency of water molecules in the grain is significantly improved, and the drying effect is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with the drawings and embodiments.

[0032] The rotary lifting assembly includes a servo motor 41, a fixed screw 42 is fixedly connected to the output shaft of the servo motor 41, two vertical slots are opened on the fixed screw 42, an octagonal nut 43 is threadedly connected to the middle of the fixed screw 42, a fixed sleeve 44 is welded outside the octagonal nut 43, a fixed guide rod 45 is fixedly connected to the bottom of the fixed sleeve 44, and the two ends of the bottom of the fixed guide rod 45 are respectively slidably connected to two of the protrusions inside the evaporation cylinder 2, and a transmission ring 46 is sleeved outside the fixed sleeve 44.

[0033] The evaporation assembly includes an evaporation cage 51, the evaporation cage 51 is rotatably connected to the transmission ring 46, a hot air space is formed inside the evaporation cage 51, a plurality of through holes are opened on the evaporation cage 51, the outside of the evaporation cage 51 is slidably connected to four protrusions inside the evaporation cylinder 2, a hot air pipe 511 is fixedly connected to the bottom of the evaporation cage 51, the hot air pipe 511 communicates with the bottom of the evaporation cage 51, a support ring 52 is rotatably connected to the transmission ring 46, a moisture extraction cover 521 is fixedly connected to the outside of the support ring 52, a moisture extraction space is formed inside the moisture extraction cover 521, a plurality of air extraction holes are opened in the lower part of the moisture extraction cover 521, an inclined ring 53 is fixedly connected to the upper side of the moisture extraction cover 521, and the outside of the moisture extraction cover 521 and the inclined ring 53 are both slidably connected to four protrusions inside the evaporation cylinder 2. A sandwich layer is formed between the moisture extraction cover 521, the inclined ring 53 and the evaporation cylinder 2. An air suction ring pipe 531 is fixedly connected to the upper part of the moisture extraction cover 521, the air suction ring pipe 531 communicates with the moisture extraction cover 521, the air suction ring pipe 531 is located in the sandwich layer formed between the moisture extraction cover 521, the inclined ring 53 and the evaporation cylinder 2, an exhaust pipe 532 is fixedly connected to the air suction ring pipe 531, and the exhaust pipe 532 passes through the inclined ring 53 and the evaporation cylinder 2. A fixed pipe 54 is fixedly connected to the middle of the transmission ring 46, a tooth rake rod 55 is fixedly connected to the fixed pipe 54, the inside of the tooth rake rod 55 is a cavity, a plurality of hollow holes are opened on both sides of the middle of the tooth rake rod 55, the aperture of the hollow holes on the tooth rake rod 55 is smaller than the grain diameter, a rotating ring 56 is slidably connected to the side of the moisture extraction cover 521 close to the transmission ring 46, and a bent pipe 57 is fixedly connected between the fixed pipe 54 and the rotating ring 56, and the two ends of the bent pipe 57 are respectively communicated with the fixed pipe 54 and the rotating ring 56.

[0034] The apertures of the plurality of through holes on the evaporation cage 51 are all smaller than the grain diameter.

[0035] The apertures of the plurality of air extraction holes opened in the lower part of the moisture extraction cover 521 are all smaller than the grain diameter.

[0036] The closing assembly includes a vertical rod 61. Four vertical rods 61 are fixedly connected to the outside of the inclined ring 53. Four fixed columns 62 are fixedly connected to the inner side of the upper part of the evaporation cylinder 2. A closing ring 63 is supported between the four fixed columns 62. The closing ring 63 is in contact with the evaporation cylinder 2, and a compression spring 64 is connected between the closing ring 63 and the inner side of the top of the evaporation cylinder 2.

[0037] At first, under the action of the extrusion spring 64 and the fixed column 62, the closing ring 63 blocks the feeding groove at the upper part of the evaporation cylinder 2. When it is necessary to evaporate and dry the grains, the staff leads the hot air generated by the air source heat pump into the hot air pipe 511. At the same time, the external device is started to intermittently pour the grains onto the feeding hopper 3, and the servo motor 41 is started. The output shaft of the servo motor 41 rotates forward to drive the fixed screw 42 to rotate forward. Due to the guiding action of the four protrusions on the inner side of the evaporation cylinder 2 on the octagonal nut 43, the fixed kit 44 and the fixed guide rod 45, the forward rotation of the fixed screw 42 causes the octagonal nut 43, the fixed kit 44 and the fixed guide rod 45 to move upward along the four protrusions on the inner side of the evaporation cylinder 2. The fixed kit 44 drives the support ring 52, the inclined ring 53, the moisture extraction cover 521, the evaporation cage 51 and the fixed pipe 54 to move upward together. The upward movement of the inclined ring 53 drives the four vertical rods 61 to move upward together. The upward movement of the moisture extraction cover 521 and the inclined ring 53 drives the suction ring pipe 531 and the exhaust pipe 532 to move upward together. The exhaust pipe 532 moves upward along the top of the evaporation cylinder 2. The four vertical rods 61 move upward to push the closing ring 63. The closing ring 63 moves upward and disengages from the four fixed columns 62. The closing ring 63 moves upward to squeeze the extrusion spring 64. The closing ring 63 no longer blocks the feeding groove at the upper part of the evaporation cylinder 2. The grains on the feeding hopper 3 fall along the feeding groove on the evaporation cylinder 2 onto the inclined ring 53, and then slide along the inclined surface of the inclined ring 53 into the accommodation space formed by the evaporation cage 51 and the moisture extraction cover 521. With the help of the thin-layer accommodation space constructed by the evaporation cage 51 and the moisture extraction cover 521, the grains are spread orderly, so that the subsequent incoming hot air can contact the grains more smoothly and efficiently, greatly improving the drying efficiency. Then the staff starts the servo motor 41 to rotate in reverse. The reverse rotation of the servo motor 41 drives the fixed screw 42 to rotate in reverse. The reverse rotation of the fixed screw 42 drives the octagonal nut 43, the fixed kit 44 and the fixed guide rod 45 to reset. The fixed kit 44 drives the support ring 52, the inclined ring 53, the moisture extraction cover 521, the evaporation cage 51 and the fixed pipe 54 to reset together. The reset of the inclined ring 53 drives the four vertical rods 61 to reset. The four vertical rods 61 no longer squeeze the closing ring 63 and the extrusion spring 64. The reset of the extrusion spring 64 drives the closing ring 63 to contact the four fixed columns 62 again. The closing ring 63 blocks the feeding groove at the upper part of the evaporation cylinder 2 again. During the reset process, the hot air continuously enters the evaporation cage 51, and heats the grains through the numerous through holes on the evaporation cage 51, causing the temperature of the grains to gradually rise. During this process, the water molecules inside the grains continuously evaporate to form hot air with water vapor. These hot air then enter the moisture extraction cover 521 and are then sucked away by the suction ring pipe 531 and the exhaust pipe 532, thus realizing the drying treatment of the grains. Moreover, the suction ring pipe 531 will also penetrate into the interior of the grain pile between the evaporation cage 51 and the moisture extraction cover 521 through the rotating ring 56, the bent pipe 57, the fixed pipe 54 and the tooth rake rod 55 to extract the moisture therein and strengthen the drying effect.

[0038] Example 2: On the basis of Example 1, as Figure 5 , Figure 7 , Figure 10 and Figure 11 shown, it further includes a stirring assembly. The stirring assembly is arranged on the transmission ring 46 and is used for turning the grains on the evaporation cage 51. The stirring assembly includes a fixing plate 71. Both sides of the upper part of the transmission ring 46 are fixedly connected with the fixing plate 71. An internal gear ring 72 is fixedly connected between the two fixing plates 71. A rotating shaft 73 is rotatably connected to the fixing kit 44. A small gear 74 is fixedly connected to the upper part of the rotating shaft 73. The internal gear ring 72 meshes with the small gear 74. Four support rods 75 are fixedly connected to the fixing kit 44. Two limiting rings 76 are fixedly connected between the four support rods 75. A sector gear ring 77 is rotatably connected between the two limiting rings 76. The outer tooth blocks of the sector gear ring 77 mesh with the small gear 74. The inner side of the sector gear ring 77 is clamped into two vertical grooves on the fixing screw 42.

[0039] When the fixing screw 42 rotates reversely, it drives the sector gear ring 77 to rotate reversely through the two vertical grooves on the fixing screw 42. The reverse rotation of the sector gear ring 77 drives the small gear 74 and the rotating shaft 73 to rotate forward through the tooth blocks on the outer side of the sector gear ring 77. The forward rotation of the small gear 74 drives the internal gear ring 72 and the two fixing plates 71 to rotate forward. The forward rotation of the two fixing plates 71 drives the transmission ring 46, the fixed pipe 54, the rotating ring 56, the bent pipe 57 and the tooth rake rod 55 to rotate forward together. The forward rotation of the tooth rake rod 55 stirs the grains between the evaporation cage 51 and the moisture extraction cover 521. Since the tooth rake rod 55 is arranged in an inclined shape, the forward rotation of the tooth rake rod 55 shovels the grains, thereby turning the grains up, making the grains heat more evenly and significantly improving the heating effect. Moreover, tooth grooves are distributed at intervals on the tooth rake rod 55. During the forward rotation of the tooth rake rod 55, these tooth grooves will also stagger and stir the grains, thereby further dispersing the grain pile, making the grains fully exposed to the hot air, accelerating the evaporation of internal moisture and ensuring that the drying process is more efficient and thorough. Together with the suction ring pipe 531, the exhaust pipe 532 and the hollow holes on the tooth rake rod 55, when the tooth rake rod 55 turns the grains, it can also synchronously extract the moisture inside the grains, thereby greatly improving the drying efficiency of the grains. When the fixing screw 42 rotates forward, the fixing screw 42 drives the sector gear ring 77 to rotate forward. The forward rotation of the sector gear ring 77 drives the small gear 74 and the rotating shaft 73 to rotate reversely. The reverse rotation of the small gear 74 drives the internal gear ring 72, the two fixing plates 71 and the transmission ring 46 to rotate reversely. The reverse rotation of the transmission ring 46 drives the fixed pipe 54 and the tooth rake rod 55 to rotate reversely. When the servo motor 41 stops rotating, the transmission ring 46 and the tooth rake rod 55 also stop rotating.

[0040] Example 3: On the basis of Example 2, as Figure 12As shown, it further includes a jitter component. The jitter component is arranged on the fixed plate 71. A bevel block 81 is fixedly connected to the lower part of the rotating shaft 73. The edge of the bevel block 81 is bevel-shaped. A fixed ring 82 is also fixedly connected between the two fixed plates 71. A number of circular columns 83 are fixedly connected to the inner side of the fixed ring 82.

[0041] When the rotating shaft 73 rotates forward, it drives the bevel block 81 to rotate forward. The forward rotation of the bevel block 81 pushes one of the circular columns 83 upward through the bevel of the bevel block 81. The upward lifting of one of the circular columns 83 drives the fixed ring 82 and the two fixed plates 71 to lift together. The lifting of the two fixed plates 71 drives the transmission ring 46 to lift. The lifting of the transmission ring 46 drives the evaporation cage 51, the support ring 52, the moisture extraction cover 521, the inclined ring 53, the fixed pipe 54 and the rake rod 55 to lift upward together. When the bevel block 81 continues to rotate forward and no longer squeezes one of the circular columns 83 upward, under the action of gravity, the two fixed plates 71 and the transmission ring 46 reset downward. By intermittently driving the evaporation cage 51, the moisture extraction cover 521, the rake rod 55 and the grains between the evaporation cage 51 and the moisture extraction cover 521 to reciprocate up and down through the bevel block 81, the grains are fully shaken and scattered, the grains are heated more evenly, and the latent moisture inside is also accelerated to be discharged. The evaporation efficiency of the grain water molecules is significantly improved, and the drying effect is further enhanced. When the servo motor 41 stops rotating, the bevel block 81 no longer pushes the circular column 83 upward.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
