Description

Technical Field

[0001] The invention belongs to the field of dryers, in particular to an intelligent through-type vacuum dryer. Background Art

[0002] In the leather manufacturing process, the moisture content of leather needs to be reduced from 60%-75% to 16%-18% after wet processing. At present, tanneries at home and abroad generally use evaporation drying, which is to first turn the moisture or solvent in the leather into steam and then drive away the steam. The vacuum dryer is the main equipment of the evaporation drying method. It forms a negative pressure state around the leather, and a large humidity gradient is formed between the inner and outer layers of the leather and between the surface and the surrounding medium, which accelerates the vaporization speed and achieves the purpose of rapid drying.

[0003] However, it is difficult for existing vacuum dryers to produce leather products with a moisture content of 16%-18%, because wet leather of different materials has different water absorption rates, and the size of the leather may also be different, which further leads to different moisture contents of the leather. Therefore, when using a vacuum dryer for evaporative drying, the moisture content of the leather is difficult to meet the standard. If it is over-dried, the leather will easily shrink. If the drying time is short, the moisture content of the leather will exceed the standard, which will affect the quality of the leather product. Using a more precise vacuum dryer will be very expensive and have a low penetration rate. Summary of the invention

[0015] The beneficial effects of the present invention are as follows: 1. Since the metal chain has its own slot, after the upper plug plate and the lower plug plate are closed, the drying device can form a relatively sealed space to prevent interference from moisture in the external environment and prevent the loss of internal heat.

[0016] 2. After each heating, the upper plug plate and the lower plug plate are separated from each other, so that the internal heat and water vapor can diffuse and the temperature inside the drying device can be quickly restored to its original state. In this way, the drying time is fixed each time, which is conducive to the timely and quantitative production of products.

[0017] 3. Since the device is symmetrical, the metal chain belt can dry the leather regardless of whether it rotates clockwise or counterclockwise. The dried leather will stick to the outer surface of the metal chain belt and cannot automatically detach from the metal chain belt. Manual operation is required to remove the leather, causing unnecessary trouble. With the side modification rod, when the leather moves to the end point of the metal chain belt, the push rod on the side modification rod is accurately inserted into the slot of the metal chain belt to push the leather on the outer surface of the metal chain belt outward. In the process of being pushed up, the leather falls off from the outer surface of the metal chain belt, thereby solving the problem of leather easily sticking to the outer surface of the metal chain belt.

[0018] 4. When the upper plug plate is plugged into the lower plug plate, the plug connector will also be slidably connected to the metal chain belt through the slot, and the leather is located on the upper surface of the metal chain belt, so the leather will be stuck in the slot of the metal chain belt under the thrust of the plug connector. Under the squeezing action of the plug connector, the leather is fixed on the metal chain belt to prevent the leather from dehydrating and curling up in a high temperature environment, which will lead to uneven heating of the leather. At this time, the heater heats up, the temperature inside the drying device rises, and the water vapor evaporated from the leather is discharged to the outside through the exhaust pipe.

[0019] 5. When the lower plug plate slides up and plugs into the upper plug plate, the protrusion of the hollow jet plate slides into the interior of the metal chain belt through the slot, and the compression soft strip is compressed under the extrusion of the metal chain belt. The gas inside the compression soft strip is ejected from the air hole slot of the hollow jet plate and blown into the interior of the drying device, realizing airflow exchange and preventing the air inside the drying device from being too humid.

[0020] 6. When the upper end cover is pressed down, it will be engaged with the bottom shell. At this time, the upper end cover is stationary, and the driving motor is still pushing the hollow rod to continue to press down. At this time, the bottom end of the vertical long tube slides downward along the inner wall of the isolation bottom sleeve, and the fan-shaped baffle is pushed open. If the user continues to inject a specific amount of water vapor through the hollow rod, then when the drying device is working, the water vapor content inside will be the same as the water vapor content introduced by the hollow rod, thereby ensuring that the humidity inside the drying device is a fixed value when it is working, preventing the leather from being over-dried and shrinking.

The user places the leather to be dried on the left side of the upper surface of the metal chain belt 12, and after the fixed base 4 is started, the side modification rods 6 on both sides are driven to rotate by rotating the crawler 3. When the side modification rods 6 rotate, the metal chain belt 12 rotates clockwise under the action of friction, and the leather enters the drying device 1 for drying processing. At this time, the metal chain belt 12 stops rotating under the action of the fixed base 4, the upper plug plate 5 slides downward under the action of the pushing motor 2, and the lower plug plate 7 moves forward under the action of the fixed base 4. The upper plug plate 5 and the lower plug plate 7 slide upward, and the ends of the upper plug plate 5 and the lower plug plate 7 are inserted into each other and closed through the slots 11. Then the upper plug plate 5 starts to heat up and the leather is dried. After drying, the metal chain belt 12 continues to rotate to transport the dried leather to the right side of the metal chain belt 12. As the metal chain belt 12 continues to rotate, the leather is separated from the metal chain belt 12 and collected. Since the metal chain belt 12 has its own slot 11, after the upper plug plate 5 and the lower plug plate 7 are closed, the drying device 1 can form a relatively sealed space to prevent interference from water vapor in the external environment and prevent internal heat loss. After each heating is completed, the upper plug plate 5 and the lower plug plate 7 are separated from each other to diffuse the internal heat and water vapor, so that the temperature inside the drying device 1 quickly returns to its original state. In this way, the drying time is fixed each time, which is conducive to the timely and quantitative production of products.

[0026] The upper plug plate 5 includes an upper end cover 51, a circular groove is provided in the middle of the inner cavity of the upper end cover 51, and an exhaust pipe 8 is fixedly connected to the middle of the inner cavity of the upper end cover 51 through the circular groove. The inner cavity of the upper end cover 51 is evenly provided with square grooves, and a heater 52 is fixedly connected to the inner cavity of the upper end cover 51 through the square groove. The lower surface of the upper end cover 51 is symmetrically provided with plug connectors 53. When the upper plug plate 5 is plugged into the lower plug plate 7, the plug connector 53 will also be slidably connected to the metal chain belt 12 through the slot 11, and the leather is located on the upper surface of the metal chain belt 12, so the leather will be stuck in the slot 11 of the metal chain belt 12 under the thrust of the plug connector 53. Under the squeezing action of the plug connector 53, the leather is fixed on the metal chain belt 12 to prevent the leather from dehydrating and curling up in a high temperature environment, thereby causing uneven heating of the leather. At this time, the heater 52 generates heat, the temperature inside the drying device 1 rises, and the water vapor evaporated from the leather is discharged to the outside through the exhaust pipe 8.

[0027] Both ends of the lower surface of the upper plug plate 5 are slidably connected to the inner cavity of the metal chain belt 12 through the slot 11, the upper surface of the heater 52 is clamped with the inner cavity of the upper end cover 51 through the square groove, the upper surface of the plug connector 53 is fixedly connected to the lower surface of the upper end cover 51, and the lower surface of the plug connector 53 is slidably connected to the inner cavity of the metal chain belt 12 through the slot 11.

[0028] The side modification rod 6 includes a transmission roller rod 61, a double-grooved cylinder 62 is sleeved in the middle of the outer surface of the transmission roller rod 61, side guide plates 63 are symmetrically arranged on both sides of the double-grooved cylinder 62, and the inner wall of the side guide plate 63 is slidably connected with a push head rod 64, and hinged rotating plates 65 are symmetrically arranged on both sides of the outer surface of the push head rod 64, and a return spring 66 is fixedly connected to the middle of the outer surface of the hinged rotating plate 65. Since the device has symmetry, the metal chain belt 12 can dry the leather regardless of whether it rotates clockwise or counterclockwise. The dried leather will stick to the outer surface of the metal chain belt 12 and cannot be automatically detached from the metal chain belt 12. Manual operation is required to remove the leather, causing unnecessary trouble. With the side modification rod 6, when the leather moves to the end point of the metal chain belt 12, the push head on the side modification rod 6 The rod 64 is accurately inserted into the slot 11 of the metal chain belt 12, and the leather on the outer surface of the metal chain belt 12 is pushed outward. In the process of being pushed up, the leather falls off the outer surface of the metal chain belt 12, thereby solving the problem that the leather is easily adhered to the outer surface of the metal chain belt 12. Then, the push head rod 64 continues to rotate with the transmission roller rod 61, and is separated from the slot 11 of the metal chain belt 12. The outer surface of the push head rod 64 and the outer surface of the metal chain belt 12 are squeezed against each other, and the push head rod 64 slides down along the inner wall of the side guide plate 63. At this time, the hinged rotating plate 65 rotates with the sliding of the push head rod 64, and the return spring 66 is deformed by the force. When the push head rod 64 is accurately inserted into the slot 11 of the metal chain belt 12 next time, the return spring 66 will give the push head rod 64 an upward thrust through the hinged rotating plate 65, so that the push head rod 64 extends out of the side guide plate 63 to perform the next work.

[0029] Both sides of the outer surface of the transmission roller rod 61 are rollingly connected to the inner wall of the metal chain belt 12, both ends of the outer surface of the transmission roller rod 61 are rollingly connected to the inner wall of the rotating track 3, both sides of the outer surface of the side guide plate 63 are fixedly connected to the inner cavity of the double-groove cylinder 62 through long grooves, the bottom of the outer surface of the push head rod 64 is slidingly connected to the inner wall of the side guide plate 63, one end of the articulated rotating plate 65 is fixedly connected to the upper surface of the side guide plate 63, and the other end of the articulated rotating plate 65 is fixedly connected to the outer surface of the push head rod 64.

[0030] The lower plug plate 7 includes a bottom plate shell 71, and a hollow jet plate 72 is fixedly connected to the bottom of the inner wall of the bottom plate shell 71. The top of the inner cavity of the hollow jet plate 72 is evenly provided with air hole grooves, and the top of the inner cavity of the hollow jet plate 72 is fixedly connected with a compression soft strip 73 through the air hole groove. When the lower plug plate 7 slides up and is plugged into the upper plug plate 5, the protrusion of the hollow jet plate 72 slides into the interior of the metal chain belt 12 through the slot 11, and the compression soft strip 73 is compressed under the squeezing action of the metal chain belt 12, and the gas inside the compression soft strip 73 is ejected from the air hole groove of the hollow jet plate 72 and blown into the interior of the drying device 1, so as to realize airflow exchange and prevent the air inside the drying device 1 from being too humid.

[0031] The axis center of the lower surface of the bottom plate shell 71 is slidably connected to the upper surface of the fixed base 4 through a push rod, the lower surface of the hollow jet plate 72 is fixedly connected to the inner wall of the lower plug plate 7, and the number of the compression soft strips 73 is four.

[0032] The exhaust pipe 8 comprises a vertical long tube 81, a baffle ring 83 is fixedly connected to the lower part of the outer surface of the vertical long tube 81, an isolation bottom sleeve 84 is slidably connected to the bottom end of the outer surface of the vertical long tube 81, an advance spring 82 is fixedly connected to the upper surface of the isolation bottom sleeve 84, an outlet is provided at the bottom of the inner cavity of the isolation bottom sleeve 84, an external connecting ring is fixedly connected to the axis of the lower surface of the isolation bottom sleeve 84, and a fan-shaped baffle plate 85 is rotatably connected to the lower surface of the isolation bottom sleeve 84 through the external connecting ring. When the upper end cover 51 is pressed down, it will The bottom plate shells 71 are interlocked with each other. At this time, the upper end cover 51 is stationary, and the driving motor 2 is still pushing the hollow rod downward. At this time, the bottom end of the vertical long cylinder 81 slides downward along the inner wall of the isolation bottom sleeve 84, and the fan-shaped baffle 85 is pushed open. If the user continues to inject a specific amount of water vapor through the hollow rod, then when the drying device 1 is working, the water vapor content inside will be the same as the water vapor content introduced by the hollow rod, thereby ensuring that the humidity inside the drying device 1 is a fixed value when it is working, preventing the leather from being over-dried and shrinking.

[0033] The top end of the vertical cylinder 81 is fixedly connected to the output shaft of the push motor 2 through a hollow rod, the top end of the advance spring 82 is fixedly connected to the lower surface of the retaining ring 83, the bottom end of the advance spring 82 is fixedly connected to the upper surface of the isolation bottom sleeve 84, and the upper part of the outer surface of the isolation bottom sleeve 84 is fixedly connected to the middle part of the inner cavity of the upper end cover 51 through a circular groove.

[0034] The specific workflow is as follows: The user places the leather to be dried on the left side of the upper surface of the metal chain belt 12. After the fixed base 4 is started, the side modified rods 6 on both sides are driven to rotate by rotating the crawler 3. When the side modified rods 6 rotate, the metal chain belt 12 rotates clockwise under the action of friction, and the leather enters the drying device 1 for drying processing. At this time, the metal chain belt 12 stops rotating under the action of the fixed base 4, and the upper plug plate 5 slides downward under the action of the pushing motor 2, and the lower plug plate 7 slides upward under the action of the fixed base 4. The ends of the upper plug plate 5 and the lower plug plate 7 are both inserted into each other through the slot 11 and tightly closed. Then the upper plug plate 5 starts to heat up, and the leather is dried. After the leather is tied, the metal chain belt 12 continues to rotate and transports the dried leather to the right side of the metal chain belt 12. As the metal chain belt 12 continues to rotate, the leather is separated from the metal chain belt 12 and collected. Since the metal chain belt 12 has its own slot 11, after the upper plug plate 5 and the lower plug plate 7 are closed, the drying device 1 can form a relatively sealed space to prevent interference from moisture in the external environment and prevent internal heat loss. After each heating is completed, the upper plug plate 5 and the lower plug plate 7 are separated from each other to diffuse the internal heat and moisture, so that the temperature inside the drying device 1 quickly returns to its original state. In this way, the drying time is fixed each time, which is conducive to the timely and quantitative production of products.

[0035] When the upper plug plate 5 is plugged into the lower plug plate 7, the plug connector 53 will also be slidably connected to the metal chain belt 12 through the slot 11, and the leather is located on the upper surface of the metal chain belt 12, so the leather will be stuck in the slot 11 of the metal chain belt 12 under the thrust of the plug connector 53. Under the squeezing action of the plug connector 53, the leather is fixed on the metal chain belt 12 to prevent the leather from dehydrating and curling up in a high temperature environment, thereby causing uneven heating of the leather. At this time, the heater 52 generates heat, the temperature inside the drying device 1 rises, and the water vapor evaporated from the leather is discharged to the outside through the exhaust pipe 8.

[0036] Since the device is symmetrical, the metal chain belt 12 can dry the leather regardless of whether it rotates clockwise or counterclockwise. The dried leather will stick to the outer surface of the metal chain belt 12 and cannot automatically detach from the metal chain belt 12. Manual operation is required to remove the leather, causing unnecessary trouble. With the side modification rod 6, when the leather moves to the end point of the metal chain belt 12, the push rod 64 on the side modification rod 6 is accurately inserted into the slot 11 of the metal chain belt 12, pushing the leather on the outer surface of the metal chain belt 12 outward. In the process of being pushed up, the leather falls off from the outer surface of the metal chain belt 12, thereby solving the problem of leather susceptibility. The problem of easy sticking to the outer surface of the metal chain belt 12, then the push head rod 64 continues to rotate with the transmission roller rod 61, and is separated from the slot 11 of the metal chain belt 12. The outer surface of the push head rod 64 and the outer surface of the metal chain belt 12 are squeezed against each other, and the push head rod 64 slides down along the inner wall of the side guide plate 63. At this time, the hinged rotating plate 65 rotates with the sliding of the push head rod 64, and the return spring 66 is deformed by the force. When the push head rod 64 is accurately inserted into the slot 11 of the metal chain belt 12 next time, the return spring 66 will give the push head rod 64 an upward thrust through the hinged rotating plate 65, so that the push head rod 64 extends out of the side guide plate 63 to perform the next work.

[0037] When the lower plug plate 7 slides up and is plugged into the upper plug plate 5, the protrusion of the hollow jet plate 72 slides into the interior of the metal chain belt 12 through the slot 11, and the compression soft strip 73 is compressed under the squeezing action of the metal chain belt 12, and the gas inside the compression soft strip 73 is ejected from the air hole groove of the hollow jet plate 72 and blown into the interior of the drying device 1, realizing airflow exchange and preventing the air inside the drying device 1 from being too humid.

[0038] When the upper end cover 51 is pressed down, it will be engaged with the bottom plate shell 71. At this time, the upper end cover 51 is stationary, and the driving motor 2 is still pushing the hollow rod to continue to press down. At this time, the bottom end of the vertical long cylinder 81 slides downward along the inner wall of the isolation bottom sleeve 84, and the fan-shaped baffle 85 is pushed open. If the user continues to inject a specific amount of water vapor through the hollow rod, then when the drying device 1 is working, the water vapor content inside will be the same as the water vapor content introduced by the hollow rod, thereby ensuring that the humidity inside the drying device 1 is a fixed value when it is working, preventing the leather from being over-dried and shrinking.
