Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a solid-liquid combined belt drying device. Background Technique

[0002] The belt drying device is a common drying equipment, which is mainly used to dry materials. It can evaporate the moisture in the materials through ventilation or heating, etc. During the drying process, it can reduce the number of microorganisms, lower the enzyme activity, prevent the materials from deteriorating, improve the preservation period and stability of the materials, facilitate storage and transportation, and can also process and treat the dried materials, etc. The belt drying device can be traced back to the early development of industrial drying and has been continuously developed with the progress of technology. In actual applications, the belt drying device is used to process various types of materials, such as food, medicine, chemical products, agricultural products, etc. However, the existing drying devices can only dry pastes during use and cannot use the same device to dry solids again. Therefore, when drying solids, other devices need to be purchased again, which not only occupies a large area but also has extremely high usage costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a solid-liquid combined belt drying device to solve the problem that the device cannot dry solids mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A solid-liquid combined belt drying device includes a drying box. The outer surfaces of both ends of the drying box are rotatably installed with box covers, and the box covers are attached to the outer surface of the drying box. The outer surface of the drying box is fixedly installed with a air supply frame, and the outer surface of the air supply frame is fixedly installed with a volute air blower. The inside of the drying box is fixedly installed with a conveyor belt, and evenly distributed block-shaped pieces are fixedly installed on the outer surfaces of both ends of the conveyor belt, and the outer surfaces of the block-shaped pieces on the outer surface of the conveyor belt are attached to each other. A solid drying structure is arranged inside the drying box, and through the solid drying structure, block-shaped objects can be dried.

[0005] Preferably, the solid drying structure includes: infrared tubes, which are fixedly installed inside the drying box, and heat exchange fins are fixedly installed inside the drying box, and the heat exchange fins are located between the infrared tubes and the air supply frame. Through holes are evenly opened on the outer surface of one end of the air supply frame close to the conveyor belt. An air outlet groove is fixedly installed on the outer surface of one end of the drying box, and heat exchange fins are fixedly arranged inside the air outlet groove. An external movable conveyor belt is arranged at one end of the drying box far from the volute air blower, and the outer surface of the external movable conveyor belt is attached to the outer surface of the drying box.

[0006] With the above technical solution, the solid to be dried can be sent into the interior of the drying box through an external mobile conveyor belt, and the solid can be transported through the transportation and movement of the conveyor belt. During the transportation process, the volute air blower will draw external air into the interior of the air supply frame and disperse it, enabling the air to be evenly ejected and pass through the infrared tubes and heat exchange fins. The solid is baked by the infrared tubes, and the hot air sent out will heat the heat exchange fins through the air outlet groove, enabling the air sent out through the air supply frame to carry away the heat of the heat exchange fins. Cooperating with the infrared tubes to jointly dry the solid materials, the cost problem during use is reduced, and the device can dry solid materials.

[0007] Preferably, a paste conveyor is fixedly arranged at one end of the interior of the drying box away from the volute air blower. An outlet paste pipe is rotatably installed inside the drying box, and the outlet paste pipe inside the drying box is in plug-in connection with the paste conveyor. Moreover, the outer surfaces of the outlet paste pipe and the paste conveyor inside the drying box do not contact the outer surface of the external mobile conveyor belt.

[0008] With the above technical solution, when in use, the outlet paste pipe can be pulled out so that the external mobile conveyor belt will not be affected when transporting solid materials, and the paste can be sent out from the paste conveyor when drying the paste.

[0009] Preferably, a first electromagnetic valve is arranged between the air supply frame and the volute air blower. The drying box is interconnected with the air outlet groove, and a second electromagnetic valve is fixedly installed between the air outlet groove and the drying box.

[0010] With the above technical solution, when creating a vacuum environment for drying the paste, gas is prevented from entering through the volute air blower and the air outlet groove, enabling the drying box to remain in a closed state.

[0011] Preferably, a rotating meshing mechanism is arranged between the conveyor belt and the drying box. Through the rotating meshing mechanism, while the conveyor belt rotates, the dried solid blocks or pastes are discharged.

[0012] With the above technical solution, the conveyor belt and the spiral conveyor blade can work simultaneously, enabling the paste or solid materials to be sent out to the outside through the spiral conveyor blade after drying.

[0013] Preferably, the rotating meshing mechanism includes: a spiral conveyor blade. The spiral conveyor blade is rotatably installed on the outer surface of one end of the drying box, and the outer surface of the drying box is closely attached to the side surface of the spiral conveyor blade. An output motor is fixedly installed on the outer surface of one end of the drying box close to the volute air blower, and the output motor is connected to the rotating shaft of the conveyor belt. A first gear is fixedly installed at the output end of the output motor. A second gear is fixedly installed at one end of the spiral conveyor blade located outside the drying box, and the second gear meshes with the first gear, and the diameter of the first gear is larger than that of the second gear.

[0014] By adopting the above technical solution, the diameter difference between the first gear and the second gear is used to increase the rotation speed of the second gear, so that the second gear can drive the spiral conveying blade to rotate faster, thereby increasing the rotation speed of the spiral conveying blade, so that the items transported from the conveyor belt after drying can be quickly discharged from the drying box.

[0015] Preferably, a vacuum pump is fixedly installed on the outer surface of one end of the air supply frame away from the volute blower, and the vacuum pump is connected to the air supply frame. A discharge port is provided at one end of the drying box close to the spiral conveying blade, and the drying box is connected to the receiving container.

[0016] By adopting the above technical solution, the discharge port of the drying box is connected to the receiving container when drying the paste material, and the air in the drying box is extracted by a vacuum pump, so that the paste can automatically expand when it is placed on the conveyor belt, thereby accelerating the drying of the infrared tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the solid-liquid two-in-one belt drying device:

[0018] 1. When drying fixed materials, you only need to open the box cover on one side and fix the external mobile conveyor belt on the side surface of the drying box. The solid material can be sent into the drying box through the external mobile conveyor belt. The external air is drawn into the air supply frame by the volute blower and evenly dispersed and sprayed out. The sprayed air can pass through the infrared tube and heat exchange fins and blow toward the solid to be dried. The hot air discharged through the air outlet slot will heat the heat exchange fins, so that the air blown out of the air supply frame can be heated, so that the solid material can be dried faster, and the discharged hot air can be reused.

[0019] 2. With the start of the output motor, the conveyor belt will rotate accordingly, causing the first gear to rotate along with the conveyor belt, and at the same time driving the second gear meshing with the first gear to rotate along with it. Due to the diameter difference between the first gear and the second gear, the rotation speed of the spiral conveying blade is higher than the rotation speed of the conveyor belt, so that the material entering the spiral conveying blade will not accumulate in the drying box and can be discharged smoothly, so that the spiral conveying blade can work together with the conveyor belt;

[0020] 3. When drying paste materials, it is necessary to close and fix the box covers on both sides of the drying box, and at the same time close the first solenoid valve and the second solenoid valve so that the drying box can be kept in a vacuum state after the vacuum pump is started. The vacuum state of the drying box allows the paste discharged from the paste conveyor and the paste outlet pipe to automatically expand and be dried by the infrared tube. When drying solids, the first solenoid valve and the second solenoid valve remain open so that air can circulate in the drying box, allowing the drying box to dry both pastes and solids.

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: a solid-liquid two-in-one belt drying device, including a drying box 1, box covers 2 are rotatably installed on the outer surfaces of both ends of the drying box 1, and the box covers 2 are attached to the outer surface of the drying box 1. An air supply frame 11 is fixedly installed on the outer surface of the drying box 1, and a volute blower 3 is fixedly installed on the outer surface of the air supply frame 11. A conveyor belt 5 is fixedly installed inside the drying box 1, and block-shaped pieces are evenly fixedly installed on the outer surfaces of both ends of the conveyor belt 5, and the outer surfaces of the block-shaped pieces on the outer surface of the conveyor belt 5 are attached to each other. A solid drying structure is provided inside the drying box 1, and the block-shaped objects can be dried through the solid drying structure.

[0030] When cleaning or maintaining the drying oven 1, the cabinet covers 2 on both sides of the drying oven 1 can be opened, which facilitates the disassembly of the internal parts of the drying oven 1 or the cleaning of the residual material residues inside the drying oven 1 during drying. The block-shaped pieces fixed on both sides of the conveyor belt 5 can move together with the conveyor belt 5 when the conveyor belt 5 rotates, preventing the material from running outside during the drying and movement process and reducing the loss of materials during drying.

[0031] The solid drying structure includes: an infrared tube 12, which is fixedly installed inside the drying oven 1. A heat exchange fin 13 is fixedly installed inside the drying oven 1, and the heat exchange fin 13 is located between the infrared tube 12 and the air supply frame 11. The outer surface of one end of the air supply frame 11 close to the conveyor belt 5 is evenly provided with through holes. An air outlet groove 14 is fixedly installed on the outer surface of one end of the drying oven 1, and heat exchange fins 13 are fixedly arranged inside the air outlet groove 14. An external movable conveyor belt 16 is arranged at one end of the drying oven 1 far from the volute blower 3, and the outer surface of the external movable conveyor belt 16 is attached to the outer surface of the drying oven 1.

[0032] When drying solid materials, it is necessary to open the cabinet cover 2 on one side of the drying oven 1, insert and fix the external movable conveyor belt 16 on the side surface of the drying oven 1, and then start the volute blower 3, so that the volute blower 3 sucks air into the air supply frame 11, enabling the air to be evenly dispersed through the through holes on the outer surface of the air supply frame 11, passing through the infrared tube 12 and blowing towards the solid materials to be dried. Then the hot air is discharged to the outside through the air outlet groove 14. The discharged hot air heats the heat exchange fins 13, enabling the incoming air to be heated by passing through the heat exchange fins 13. The connection between the drying oven 1 and the external movable conveyor belt 16 can reduce the probability of hot air leakage during drying, and the heat exchange fins 13 can recover the heat of the discharged hot air, accelerating the drying efficiency of the materials.

[0033] A paste conveyor is fixedly arranged at one end of the drying oven 1 far from the volute blower 3. An outlet paste pipe is rotatably installed inside the drying oven 1, and the outlet paste pipe inside the drying oven 1 is in plug-in connection with the paste conveyor, and the outer surfaces of the outlet paste pipe and the paste conveyor inside the drying oven 1 do not contact the outer surface of the external movable conveyor belt 16.

[0034] When drying paste materials, the paste materials can be evenly coated on the conveyor belt 5 through the conveying of the paste conveyor and the swinging of the outlet paste pipe, enabling the device to dry paste-like materials. When drying solid materials, the outlet paste pipe can be removed so that the external movable conveyor belt 16 will not be affected during feeding.

[0035] A first electromagnetic valve 4 is provided between the air supply frame 11 and the volute blower 3 , the drying box 1 and the air outlet slot 14 are connected to each other, and a second electromagnetic valve 15 is fixedly installed between the air outlet slot 14 and the drying box 1 .

[0036] When the paste material is dried through the first solenoid valve 4 and the second solenoid valve 15 , gas will not enter the interior of the drying box 1 through the volute blower 3 and the air outlet slot 14 to cause the vacuum state to be unable to be maintained.

[0037] A rotating meshing mechanism is provided between the conveyor belt 5 and the drying box 1 , and the conveyor belt 5 is rotated by the rotating meshing mechanism while the dried solid blocks or paste are discharged.

[0038] The spiral conveying blades 7 can rotate together with the conveyor belt 5 so that the spiral conveying blades 7 can discharge the dried material from the drying box 1 to the outside.

[0039] The rotating engagement mechanism includes: a spiral conveying blade 7, which is rotatably mounted on the outer surface of one end of the drying box 1, and the outer surface of the drying box 1 is tightly fitted with the side surface of the spiral conveying blade 7. An output motor 6 is fixedly mounted on the outer surface of one end of the drying box 1 close to the volute blower 3, and the output motor 6 is connected to the rotating shaft of the conveyor belt 5. A first gear 8 is fixedly mounted on the output end of the output motor 6, and a second gear 9 is fixedly mounted on the end of the spiral conveying blade 7 located outside the drying box 1, and the second gear 9 is meshed with the first gear 8, and the diameter of the first gear 8 is larger than the diameter of the second gear 9.

[0040] When the output motor 6 rotates, it will drive the conveyor belt 5 to rotate, and at the same time drive the first gear 8 to rotate, so that the second gear 9 meshing with the first gear 8 will rotate accordingly. The rotation of the second gear 9 allows the spiral conveying blade 7 to rotate accordingly and deliver the dried material. Due to the diameter difference between the first gear 8 and the second gear 9, the rotation speed of the second gear 9 can be faster than the rotation speed of the first gear 8, so that the rotation speed of the spiral conveying blade 7 can be faster than the conveyor belt 5, so that the dried material discharged from the conveyor belt 5 will not accumulate inside the spiral conveying blade 7.

[0041] A vacuum pump 10 is fixedly installed on the outer surface of the air supply frame 11 away from the volute blower 3, and the vacuum pump 10 is connected to the air supply frame 11. A discharge port is provided at one end of the drying box 1 close to the spiral conveying blade 7, and the drying box 1 is connected to the receiving container.

[0042] When drying paste materials, the box covers 2 on both sides of the drying box 1 need to be closed and locked, and then the vacuum pump 10 can be started to extract the air in the drying box 1, so that the paste object can automatically expand and be dried along with the baking of the infrared tube 12. The drying box 1 is connected to the container in a sealed vacuum state when drying the paste. When drying solids, it is only necessary to place the conveying device at the discharge port of the drying box 1.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
