Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving heat exchange, and particularly relates to an energy-saving double-cone drying device. Background Art

[0002] Heat exchange is the process of heat transfer between two objects or different parts of the same object due to temperature difference. Heat exchange is a necessary condition for drying, and its driving force is the temperature difference. The double-cone drying device is a common drying device that is equipped with a condenser, a vacuum pump and a dryer to form a vacuum drying device, which is usually used in the fields of chemical industry, medicine, food, etc. The double-cone drying device is a double-conical rotating tank body. Under vacuum conditions in the tank, steam or hot water is introduced into the jacket for heating, and the heat is in contact with the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the inside of the tank is in a vacuum state and the rotation of the tank body makes the material constantly turn up and down, inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

[0003] For example, in the patent document with the publication number of "CN220103609U" and the name of "A Double-Cone Dryer", the patent document includes a frame, a power device, a vacuum pumping device and a double-cone cylinder body. Among them, a cleaning mechanism is arranged in the double-cone cylinder body. The cleaning mechanism includes a rotating shaft horizontally arranged in the double-cone cylinder body. The two ends of the rotating shaft are rotationally supported on the inner wall of the double-cone cylinder body through bearings. A second motor is arranged at the right power box. The right end of the rotating shaft extends out of the double-cone cylinder body and is connected to the output shaft of the second motor. The cleaning mechanism further includes two groups of cleaning brackets symmetrically arranged in the double-cone cylinder body. Each group of cleaning brackets includes a first fixed ring fixedly connected to the rotating shaft and a movable ring sleeved outside the rotating shaft. A plurality of brush rods are evenly hinged on the outer peripheral surface of the first fixed ring. The middle of the brush rod is connected to the movable ring through a support rod. Brush hairs are arranged on the outer side of the brush rod. By arranging the cleaning mechanism, during the operation of the double-cone dryer, the inner wall of the cylinder is continuously brushed by the brush rod by using centrifugal force.

[0004] However, during the use and processing of the above-mentioned document, although the inner wall of the cylinder can be continuously brushed by the brush rod to improve the drying efficiency of the material, after the drying operation of the low-fluidity material, the discharge pipe is prone to clogging during discharging, resulting in a significant decrease in the discharge speed, which not only lengthens the overall operation time but also reduces the work efficiency of the operator. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and propose an energy-saving double-cone drying device to solve the technical problem that the discharge pipe is prone to clogging during discharging, resulting in a significant decrease in the discharge speed mentioned in the background art.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An energy-saving double-cone drying device includes a frame. A double-cone cylinder is rotatably arranged inside the frame. Feed pipes and discharge pipes are respectively arranged at both ends of the double-cone cylinder. Control valves are arranged on both the feed pipes and the discharge pipes. A discharging device for assisting the discharge pipe to discharge materials is arranged at the bottom of the frame.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 - 2 As shown, an energy-saving double-cone drying device includes a frame 1, and a double-cone cylinder 2 is rotatably installed in the frame 1. The frame 1 and the double-cone cylinder 2 are both prior arts, so the internal details of the frame 1 and the double-cone cylinder 2 are not specifically displayed or repeated in this application. The double-cone cylinder 2 can be turned over under the drive of the internal power source of the frame 1. The rotation of the double-cone cylinder 2 causes the material inside to be constantly turned up and down, inside and outside, so the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved. The two ends of the double-cone cylinder 2 are respectively installed with a feed pipe 3 and a discharge pipe 7 connected to the inside thereof, and a control valve 4 is installed on the feed pipe 3 and the discharge pipe 7 to facilitate the control of feeding and discharging.

[0022] like Figures 1 - 3 As shown, a discharging device for assisting the discharging of the discharging pipe 7 is installed at the bottom of the frame 1. The discharging device includes a moving pipe 8 adapted to the discharging pipe 7. The moving pipe 8 is located directly below the discharging pipe 7. The inner diameter of the moving pipe 8 is the same as the inner diameter of the discharging pipe 7, so that the material can fall from the discharging pipe 7 into the moving pipe 8. The moving pipe 8 is installed by sliding with the frame 1 through the moving frame. The moving frame includes a sleeve ring 15. Two symmetrically arranged mounting plates 16 are fixedly installed on the outer periphery of the sleeve ring 15, and the sleeve ring 15 is fixedly sleeved on the bottom of the moving pipe 8. Guide grooves 5 are vertically opened on the opposite sides of the frame 1, and the two guide grooves 5 are symmetrically arranged. The ends of the two mounting plates 16 that are away from each other are respectively slidably connected to the corresponding guide grooves 5, and a spring 19 is fixedly installed between the mounting plate 16 and the bottom surface of the corresponding guide groove 5. Through the sliding cooperation between the mounting plate 16 and the guide groove 5, it is convenient for the moving pipe 8 to align with the discharging pipe 7 when moving upward. The spring 19 facilitates the reset of the moving tube 8 to prevent the moving tube 8 from hindering the turning of the double-cone cylinder 2.

[0023] As shown Figures 1 - 3 in the figure, a lifting device for driving the moving frame to lift is installed on the rack 1. The lifting device includes two second electric push rods 23 symmetrically and fixedly installed at the bottom of the rack 1. A placement groove 6 is opened at the bottom of the rack 1, and a bearing frame 20 is placed in the placement groove 6. Connecting ears 24 are fixedly installed on both sides of the bearing frame 20, and the output ends of the two second electric push rods 23 are respectively fixedly connected to the connecting ears 24 on both sides of the bearing frame 20. A collection box 21 is slidably installed in the bearing frame 20, and both sides of the collection box 21 are slidably matched with the inner side of the bearing frame 20, facilitating the pulling out of the collection box 21 from the bearing frame 20. A communication pipe 22 communicating with the inside of the collection box 21 is installed on the top of the collection box 21. The communication pipe 22 is adapted to the moving pipe 8, and the inner diameters of the communication pipe 22 and the moving pipe 8 are the same, facilitating the material to fall into the collection box 21 through the moving pipe 8 and the communication pipe 22 after the communication pipe 22 is connected to the moving pipe 8, and reducing the outward diffusion of the dust of the material. The top end of the communication pipe 22 is in abutting fit with the bottom end of the moving pipe 8. When the second electric push rod 23 drives the bearing frame 20 to move upward, and the bearing frame 20 drives the collection box 21 to move upward, the collection box 21 drives the communication pipe 22 to move upward to be in abutting fit with the moving pipe 8. Thus, when the communication pipe 22 continues to move upward, it will drive the moving pipe 8 to move upward, facilitating the connection of the moving pipe 8 with the discharge pipe 7.

[0024] As shown Figures 1 - 5 in the figure, a fixing ring 9 is fixedly installed on the outer periphery of the moving pipe 8. Fixing rods are fixedly welded along the circumferential direction of the inner side of the fixing ring 9, and the other ends of the fixing rods are welded and fixed to the outer periphery of the moving pipe 8. A plurality of knocking rods 10 are hinged along the circumferential direction of the fixing ring 9. The knocking rods 10 are in an "L" shape, and a driving device for driving the plurality of knocking rods 10 to knock on the discharge pipe 7 is installed on the moving pipe 8. The driving device includes a moving ring 11 and a reciprocating component. The moving ring 11 is installed around the outer periphery of the moving pipe 8. A plurality of first hinged rods 12 are hinged along the circumferential direction of the moving ring 11, and the ends of the first hinged rods 12 far from the moving ring 11 are hinged to the corresponding knocking rods 10. The reciprocating component is installed on the moving frame and is used to drive the moving ring 11 to reciprocate up and down. During the process of the moving ring 11 reciprocating up and down, the knocking rods 10 are driven by the first hinged rods 12 to knock on the discharge pipe 7. The knocking rods 10 knock on the discharge pipe 7, causing the discharge pipe 7 to vibrate, avoiding the clogging of the material in the discharge pipe 7, and thus promoting the rapid discharge of the material.

[0025] As shown Figure 2 and Figure 3As shown in the figure, the reciprocating assembly includes two first electric push rods 18 fixedly installed on the top of the moving frame and arranged symmetrically. The two first electric push rods 18 are respectively located on the corresponding mounting plates 16. The output end of the first electric push rod 18 is fixedly installed with a slider 14. Two symmetrically arranged sliding grooves 17 are formed on the top of the moving frame. The two sliding grooves 17 are respectively located on the corresponding mounting plates 16, and the sliding groove 17 is slidably connected to the corresponding slider 14. The top of the slider 14 is hingedly installed with a second hinge rod 13 through a hinge shaft. The other end of the second hinge rod 13 is hinged to the moving ring 11. The first electric push rod 18 drives the corresponding slider 14 to reciprocate left and right along the sliding groove 17, and the slider 14 drives the moving ring 11 to reciprocate up and down through the second hinge rod 13.

[0026] As Figure 3 and Figure 4 As shown in the figure, two through grooves 27 are symmetrically arranged along the axial direction of the moving pipe 8, and the through grooves 27 penetrate the outside and inside of the moving pipe 8. Two fixing blocks 26 are fixedly installed on the moving ring 11. One side of the fixing block 26 close to the moving pipe 8 is rotatably installed with a connecting rod 28, and the connecting rod 28 is horizontally arranged. One end of the connecting rod 28 passes through the through groove 27 and extends into the inside of the moving pipe 8. The connecting rod 28 can not only slide along the corresponding through groove 27, but also rotate relative to the corresponding through groove 27. A dredging rod 25 is installed along the axial direction inside the moving pipe 8. One end of the connecting rod 28 located inside the moving pipe 8 is fixedly connected to the dredging rod 25, and the connecting rod 28 is perpendicular to the dredging rod 25. The dredging rod 25 is used to dredge the materials in the discharge pipe 7. The top end of the dredging rod 25 is a conical structure, which is convenient for the dredging rod 25 to insert into the inside of the materials.

[0027] As Figure 4 As shown in the figure, two strip plates 31 are symmetrically arranged on both sides of the outside of the moving pipe 8. The two strip plates 31 are fixedly connected to the outer circumference of the moving pipe 8, and the two strip plates 31 are both arranged along the axial direction of the moving pipe 8. The two strip plates 31 are symmetrically arranged with respect to the corresponding through groove 27. A plurality of dial plates 32 are arranged along the length direction on the opposite sides of the two strip plates 31. The plurality of dial plates 32 are arranged at equal intervals, and the plurality of dial plates 32 on the two strip plates 31 are arranged relatively staggered. A connecting plate 29 is fixedly installed on the connecting rod 28. A torsion spring 30 is sleeved on the outer circumference of the connecting rod 28. One end of the torsion spring 30 is fixedly connected to the connecting plate 29, and the other end of the torsion spring 30 is fixedly connected to the fixing block 26. Two dial rods 33 are fixedly installed on the connecting plate 29, and the dial rods 33 are in sliding fit when contacting the corresponding plurality of dial plates 32 respectively.

[0028] Working principle: As Figure 6As shown, in the initial state, the spring 19 is in its natural state, the moving tube 8 is separated from the discharge tube 7 to prevent the moving tube 8 from obstructing the flipping of the double-cone cylinder 2. Also, the connecting tube 22 is separated from the moving rod, facilitating the sliding installation of the collection box 21 within the carrying frame 20.

[0029] During use, the material to be dried is added into the interior of the double-cone cylinder 2 through the feed tube 3. Then, the double-cone cylinder 2 can be flipped under the drive of the power source within the frame 1, thereby drying the material inside it.

[0030] When it is necessary to discharge the material inside the double-cone cylinder 2, the double-cone cylinder 2 is rotated to a vertical state by the power source installed within the frame 1, so as to keep the discharge tube 7 at the bottom and in a vertical state. Then, the second electric push rod 23 is activated to drive the carrying frame 20 to move upward. The carrying frame 20 drives the collection box 21 to move upward, and the collection box 21 drives the connecting tube 22 to move upward. During the upward movement of the connecting tube 22, it abuts and cooperates with the moving tube 8. Thus, the connecting tube 22 drives the moving tube 8 to move upward. At the same time, the moving tube 8 drives the moving frame and the knocking rod 10 to move upward. When the top end of the moving tube 8 contacts the bottom end of the discharge tube 7, at this time, the moving tube 8 is respectively connected to the discharge tube 7 and the connecting tube 22, facilitating the material to fall into the collection box 21, reducing the diffusion of material dust, and at the same time stopping the second electric push rod 23 from working.

[0031] Open the control valve 4 on the discharge tube 7 to discharge the material from the discharge tube 7. During the discharge of the material, in order to prevent the material from getting stuck in the discharge tube 7 and causing poor feeding, at this time, activate the first electric push rod 18 to drive the corresponding slider 14 to reciprocate left and right along the sliding groove 17. The slider 14 drives the moving ring 11 to reciprocate up and down through the second hinge rod 13. The reciprocating up and down movement of the moving ring 11 drives the corresponding knocking rods 10 to knock on the discharge tube 7 through a plurality of first hinge rods 12 respectively, so as to vibrate the discharge tube 7, prompting the low-fluidity material to be discharged from the discharge tube 7, preventing the material from getting stuck in the discharge tube 7, and increasing the speed of material discharge.

[0032] During the up and down movement of the moving ring 11, it also drives the fixed block 26 to move up and down at the same time. The fixed block 26 drives the connecting rod 28 to move up and down along the corresponding through groove 27. The connecting rod 28 drives the dredging rod 25 to move up and down. When the dredging rod 25 moves up and down, it continuously dredges the material in the discharge tube 7, further increasing the speed of the material being discharged from the discharge tube 7.

[0033] When the connecting rod 28 moves up and down, it drives the connecting plate 29 to move up and down. The connecting plate 29 drives the toggle rods 33 on both sides of it to move up and down. During the process of the toggle rods 33 moving up and down, they are in sliding fit when contacting the corresponding multiple toggle plates 32 respectively. Since the connecting rod 28 is rotatably connected to the fixed block 26, during the process of the toggle rods 33 moving up and down, when the toggle rods 33 contact the toggle plates 32, they are in sliding fit and drive the connecting plate 29 to rotate. And because a torsion spring 30 is fixedly installed between the connecting plate 29 and the fixed block 26, after the toggle rods 33 are separated from the toggle plates 32, the torsion spring 30 will drive the connecting plate 29 to reset. At the same time, since the multiple toggle plates 32 on the two strip plates 31 are arranged vertically in a staggered manner, during the process of the toggle rods 33 on both sides of the connecting plate 29 moving up and down, they will drive the connecting plate 29 to rotate clockwise and counterclockwise respectively. Thus, the connecting plate 29 drives the connecting rod 28 to rotate clockwise and counterclockwise. When the connecting rod 28 drives the dredging rod 25 to move up and down, it simultaneously drives the dredging rod 25 to swing left and right, further improving the dredging effect of the dredging rod 25 on the discharge pipe 7 and accelerating the discharge of materials from the discharge pipe 7.

[0034] After the materials are discharged from the discharge pipe 7, they enter the connecting pipe 22 through the moving pipe 8 and then enter the collection box 21 from the connecting pipe 22. When the materials are completely discharged, the second electric push rod 23 is started to drive the bearing frame 20 to move downward. The bearing frame 20 drives the collection box 21 to move downward. The restoring force of the spring 19 drives the moving frame to reset, so that the moving pipe 8 is separated from the discharge pipe 7, avoiding the moving pipe 8 from hindering the discharge pipe 7 from flipping with the double-cone cylinder body 2. When the bearing frame 20 moves downward into the placement groove 6, at this time the connecting pipe 22 is also separated from the moving pipe 8, and then the collection box 21 is pulled out of the bearing frame 20 through the handle, facilitating the transfer of the materials in the collection box 21.

[0035] When the materials of the present invention are discharged, the moving ring 11 moves up and down to drive the knocking rod 10 to knock on the discharge pipe 7, improving the discharging speed of the materials. And when the moving ring 11 moves up and down, it drives the dredging rod 25 to dredge the materials in the discharge pipe 7 through the connecting rod 28, further improving the discharging speed of the materials from the discharge pipe 7. At the same time, during the process of the connecting rod 28 moving up and down, it drives the toggle rods 33 on both sides of it to move up and down through the connecting plate 29. During the process of the toggle rods 33 moving up and down, they are in sliding fit when contacting the corresponding multiple toggle plates 32 respectively, thus driving the connecting plate 29 to rotate clockwise and counterclockwise. The connecting plate 29 drives the dredging rod 25 to swing left and right through the connecting rod 28, realizing that the dredging rod 25 can swing left and right while moving up and down, further improving the dredging effect on the discharge pipe 7 and accelerating the discharge of materials from the discharge pipe 7. Thus, after the drying operation of the low-fluidity materials, the phenomenon of blockage of the discharge pipe 7 during discharging is avoided, the discharging speed is improved, not only the overall operation time is reduced, but also the work efficiency of the operator is improved.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
