[0002] When some materials are produced and processed, the staff need to use drying equipment to dry the materials. The drying equipment used for materials on the market is mainly composed of a drying fan and a collection box. When this drying device is in use, the staff will place the materials inside the collection box in advance, and then turn on the drying fan. The drying fan can transport high-temperature gas to the inside of the collection box. After the high-temperature gas comes into contact with the material inside the collection box, the water vapor inside the material can evaporate quickly.

At the same time, when the air outlet pipe slides along the surface of the collecting pipe, the air outlet pipe can drive the support plate to lift the material.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] See also Figure 1-8 As shown, the present invention is a drying device for materials, comprising an equipment housing 1 and a cleaning structure 6 and a drying device 33 detachably connected to the equipment housing 1. A feed port 4 is provided on the equipment housing 1, a collecting pipe 20 is passed through the middle of the inner cavity of the equipment housing 1, a chain plate conveyor belt 8 is passed through the interior of the feed port 4, a transmission rod 9 and a driven rod 14 are passed through the chain plate conveyor belt 8, both ends of the transmission rod 9 and the driven rod 14 are fixedly connected with a buckle plate 10, and the buckle plate 10 is rotatably connected with a connecting frame 7 on the side away from the chain plate conveyor belt 8, and the connecting frame 7 is fixedly connected to the equipment housing 1, and a transmission structure 3 is detachably connected to one of the connecting frames 7, and the output end of the transmission structure 3 is connected to the buckle plate 10 on the transmission rod 9;

[0033] The cleaning structure 6 and the drying device 33 can be selected as existing structures on the market, wherein the cleaning structure 6 is used to clean the dust on the abutment block 30 and the support plate 12, and the drying device 33 is used to transfer heat to the interior of the equipment housing 1. The transmission structure 3 is a reduction motor currently available on the market. When the transmission structure 3 is in use, it can drive the transmission rod 9 to rotate through the buckle plate 10, and at this time, the chain conveyor belt 8 can realize the transportation of strip or floc-like materials.

[0034] The chain conveyor belt 8 includes a rotating plate 11, and rotating blocks 13 are rotatably connected to both sides of the rotating plate 11 near the end, and a support plate 12 is distributed between the two rotating blocks 13. The lower part of the rotating block 13 near one end of the support plate 12 is fixedly connected to an abutment block 30, and the bottom surface of the support plate 12 is fixedly connected to a sliding rod 29, and the lower part of the sliding rod 29 penetrates the abutment block 30. The bottom surface of the support plate 12 is fixedly connected to an outlet pipe 16, and the lower end of the outlet pipe 16 abuts against the collection pipe 20;

[0035] The rotating plate 11, the rotating block 13 and the support plate 12 are rectangular plate structures. The lower part of the sliding rod 29 penetrates the abutment block 30, so that the use height of the support plate 12 can be adjusted. When the use height of the support plate 12 is higher than the rotating plate 11, the support plate 12 can lift the strip or flocculent material on the rotating plate 11. At this time, the lower part of the material is in an overhead state, which can facilitate the strip or flocculent material to release water vapor downward, realize the two-way release of water vapor from the strip or flocculent material, and realize the rapid separation of water vapor in the material from the material.

[0036] When in use, the output end of the transmission structure 3 drives the transmission rod 9 to rotate through the buckle plate 10. At this time, the buckle plate 10 can drive the chain conveyor belt 8 to rotate in the equipment housing 1, so that the chain conveyor belt 8 can drive the material transportation. At the same time, when the air outlet pipe 16 slides along the surface of the collecting pipe 20, the air outlet pipe 16 can drive the support plate 12 to lift the material.

[0037] Connecting ear blocks 25 are fixedly connected to both sides of the rotating plate 11 near the ends, and rotating ear blocks 27 are fixedly connected to both sides of the rotating block 13. A through rod 28 runs through the rotating ear block 27 and the connecting ear block 25.

[0038] When the penetrating rod 28 penetrates the rotating ear block 27 and the connecting ear block 25 , the rotating block 13 can be rotatably connected to the rotating plate 11 , and the supporting plate 12 can also rotate relative to the rotating plate 11 .

[0039] The bottom surfaces of the rotating plate 11 and the rotating block 13 are fixedly connected with a buckle block 17. The edge of the buckle plate 10 is provided with snap-fit ​​notches 15 at equal intervals. The snap-fit ​​notches 15 provided on the buckle plate 10 can be snap-fitted with the buckle block 17.

[0040] When the output shaft of the transmission structure 3 drives the buckle plate 10 on the transmission rod 9 to rotate, the buckle plate 10 can be engaged with the buckle block 17 on the rotating plate 11 and the rotating block 13 through the engaging notch 15, so that the buckle plate 10 can drive the chain conveyor belt 8 to rotate.

[0041] The lower end of the sliding rod 29 is fixedly connected to the limit block 31, the support plate 12 is a hollow structure, the inner cavity of the air outlet pipe 16 is connected to the inner cavity of the support plate 12, and the connection portion between the air outlet pipe 16 and the support plate 12 is fixedly connected with a sealing ring 34;

[0042] When the lower end of the air outlet pipe 16 slides along the edge of the collecting pipe 20, the movement state of the support plate 12 is gradually rising and falling. At the same time, the strip and flocculent materials on the rotating plate 11 and the rotating block 13 can be shaken, so that the strip and flocculent materials can be evenly laid on the rotating plate 11 and the rotating block 13. When the support plate 12 is raised, the strip or flocculent materials on the rotating plate 11 are in an overhead state. At this time, part of the water vapor of the strip or flocculent materials will enter between the support plate 12 and the abutment block 30.

[0043] A receiving hole 32 is provided on the bottom surface of the support plate 12 near the sliding rod 29. The inner cavity of the receiving hole 32 is connected to the inner cavity of the support plate 12. The abutment block 30 can shield the receiving hole 32.

[0044] When the support plate 12 is suspended over the strip-shaped or floc-shaped materials, the lower end of the air outlet pipe 16 can abut against the metal mesh plate 19. When the staff connects the storage end of the water pump to the external pipe 18, the interior of the collecting pipe 20 is in a negative pressure state. At this time, the interior of the support plate 12 is also in a negative pressure state. The water vapor between the support plate 12 and the abutment block 30 will pass through the storage hole 32 and enter the interior of the support plate 12, which can avoid the need for water vapor to pass through the material to flow to the exhaust pipe 2, thereby improving the water vapor storage efficiency of the device. Subsequently, the water vapor inside the support plate 12 will enter the interior of the collecting pipe 20 through the air outlet pipe 16.

[0045] The height of the top surface of the collecting pipe 20 at both sides is lower than the height of the middle part. A rectangular hole is opened on the top surface of the collecting pipe 20. A metal mesh plate 19 is embedded in the rectangular hole on the top surface of the collecting pipe 20. The top surface of the metal mesh plate 19 can abut against the outlet pipe 16.

[0046] When in use, the metal mesh plate 19 can filter the water vapor transported by the air outlet pipe 16 , and the water vapor transported by the air outlet pipe 16 can pass through the metal mesh plate 19 and enter the interior of the collecting pipe 20 .

[0047] The end of the collecting pipe 20 penetrating the device housing 1 is fixedly connected with a sealing cover 5, the inner side of the sealing cover 5 is fixedly connected with the device housing 1, the end of the collecting pipe 20 away from the sealing cover 5 is fixedly connected with a sealing plate 22, the side of the sealing plate 22 away from the sealing cover 5 is fixedly connected with the inner wall of the device housing 1, the outer side of the sealing cover 5 is fixedly connected with an external pipe 18, the inner cavity of the external pipe 18 is connected with the inner cavity of the collecting pipe 20, and the side of the device housing 1 close to the sealing cover 5 is fixedly connected with a distance sensor 26;

[0048] The sealing cover body 5 can drive the collecting tube 20 to be fixed on the equipment housing 1, the inner cavity of the external tube 18 is connected with the inner cavity of the collecting tube 20, and the end of the external tube 18 facing away from the sealing cover body 5 is connected to the water pump. The detection end of the ranging sensor 26 can detect the position of the support plate 12, so that the staff can infer whether the support plate 12 is working normally.

[0049] The interior of the collecting pipe 20 is fixedly connected with a condenser pipe 21 through a fixing frame 24, and the end of the condenser pipe 21 passes through the sealing plate 22 and the device housing 1 and extends to the outside. The device housing 1 is fixedly connected with an exhaust pipe 2 just above the metal mesh plate 19, and the inner cavity of the exhaust pipe 2 is connected with the inner cavity of the device housing 1. The end of the condenser pipe 21 and the penetration portion of the sealing plate 22 are fixedly connected with a sealing ring 23;

[0050] The receiving end of the condenser 21 is connected to the coolant delivery device, and the output end of the condenser 21 is connected to the coolant receiving device. When the coolant delivery device delivers coolant to the inside of the condenser 21, the temperature of the condenser 21 can be reduced. When the water vapor delivered by the outlet pipe 16 enters the inside of the collecting pipe 20, the water vapor inside the collecting pipe 20 can meet the condenser 21 and liquefy. Finally, the liquefied water vapor can form water liquid. The water pump connected to the external pipe 18 can pump out the water vapor inside the collecting pipe 20.

[0051] It should be added that the transmission rod 9 and the driven rod 14 do not support the rotating plate 11 and the rotating block 13, and the exhaust pipe 16 will not contact the transmission rod 9 and the driven rod 14. When the rotating plate 11 and the rotating block 13 are moving, the rotating plate 11 and the rotating block 13 may drive part of the steam to move. The transmission rod 9 and the driven rod 14 are not supported by the rotating plate 11 and the rotating block 13, so that the steam around the rotating plate 11 and the rotating block 13 can flow to the exhaust pipe 2 through the gap between the rotating plate 11 and the rotating block 13. When the rotating plate 11 and the rotating block 13 move, the support plate 12 located below will move downward under the action of gravity. At this time, the support plate 12 will be separated from the abutment block 30, which can facilitate the cleaning structure 6 to clean up the debris between the support plate 12 and the abutment block 30. When the support plate 12 is separated from the abutment block 30, the distance sensor 26 can detect the lowest position of the support plate 12, so that it is convenient for the staff to timely inspect the support plate 12.

[0052] When the drying device is actually used, the staff connects the upper end of the exhaust pipe 2 to the steam receiving device, the water pump to the external pipe 18, the coolant delivery device to the receiving end of the condenser 21, and the coolant receiving device to the output end of the condenser 21. At the same time, when the staff connects the distance sensor 26 to the external device, the staff starts the transmission structure 3 to work, and the output end of the transmission structure 3 can drive the buckle plate 10 on the transmission rod 9 to rotate. At this time, the material conveying equipment can transport the material to the chain conveyor belt 8. When the lower end of the exhaust pipe 16 slides along the edge of the collecting pipe 20, the movement state of the support plate 12 is gradually rising and gradually falling. At the same time, the strip and flocculent materials on the rotating plate 11 and the rotating block 13 can shake and vibrate. In order to achieve uniform laying of strip and flocculent materials on the rotating plate 11 and the rotating block 13, when the support plate 12 is raised, the strip or flocculent materials on the rotating plate 11 are in an overhead state, and at this time, part of the water vapor of the strip or flocculent materials will enter between the support plate 12 and the abutment block 30. When the support plate 12 is overhead for the strip or flocculent materials, the lower end of the air outlet pipe 16 can abut against the metal mesh plate 19. When the staff connects the storage end of the water pump to the external pipe 18, the interior of the collecting pipe 20 is in a negative pressure state. At this time, the interior of the support plate 12 is also in a negative pressure state. The water vapor between the support plate 12 and the abutment block 30 will penetrate the storage hole 32 and enter the interior of the support plate 12, which can avoid the need for water vapor to penetrate the material to flow to the exhaust pipe 2, and can improve the device The water vapor collection efficiency of the support plate 12 is improved. Then, the water vapor inside the support plate 12 will enter the interior of the collecting tube 20 through the air outlet pipe 16. When the metal mesh plate 19 is in use, it can filter the water vapor transported by the air outlet pipe 16 to prevent debris from contacting the condenser tube 21. The receiving end of the condenser tube 21 is connected to the coolant delivery device. When the coolant delivery device delivers coolant to the interior of the condenser tube 21, the temperature of the condenser tube 21 can be reduced. When the water vapor transported by the air outlet pipe 16 enters the interior of the collecting tube 20, the water vapor inside the collecting tube 20 can meet the condenser tube 21 and liquefy. Finally, the liquefied water vapor can form water liquid. The water pump connected to the external pipe 18 can pump out the water vapor inside the collecting tube 20. Since the chain plate conveyor belt 8 includes a plurality of continuously spliced ​​rotating plates 11 and the rotating block 13, the steam around the rotating plate 11 and the rotating block 13 can flow to the exhaust pipe 2 through the gap between the rotating plate 11 and the rotating block 13, which can facilitate the exhaust pipe 2 to collect water vapor for drying materials. When the rotating plate 11 and the rotating block 13 move, the support plate 12 located below will move downward under the action of gravity. At this time, the support plate 12 will be separated from the abutment block 30, which can facilitate the cleaning structure 6 to clean up the debris between the support plate 12 and the abutment block 30. When the support plate 12 is separated from the abutment block 30, the ranging sensor 26 can detect the lowest position of the support plate 12. The ranging sensor 26 can transmit the information detected by the support plate 12 to the external equipment, which can facilitate the staff to timely inspect the support plate 12 through the external equipment.
