Description

Technical Field

[0001] This application relates to the technical field of drying equipment, and in particular to a laminar flow adjustable circulating air drying chamber. Background Technology

[0002] A drying room is a specialized piece of equipment for drying materials. By delivering hot air into the room, the moisture content of the materials is reduced to ensure the accuracy of subsequent processing.

[0003] Currently, existing drying rooms typically include the drying room body, heating module, air supply device, and flatbed cart. During use, the operator places the material to be dried onto the flatbed cart and pushes it to transport the material into the drying room body. Once the material is inside the drying room body, the operator closes the door and simultaneously activates the heating module and air supply device. The heating module heats the air, and the air supply device delivers the heated air into the drying room body. The hot air contacts the surface of the material on the flatbed cart, achieving heat exchange. After a preset drying time, the operator turns off the heating module and air supply device and opens the door to move the flatbed cart out of the drying room body.

[0004] However, in the use of existing drying rooms, the air supply device is mostly a single air outlet or local air supply design. The hot air can only spread in one direction in the room, resulting in significant differences in wind speed and temperature in different areas of the room. This leads to uneven distribution of hot air, which causes the materials at different positions on the flatbed to receive inconsistent heat and air volume. Some materials are over-dried, causing cracks and deformation, while other materials are not thoroughly dried and retain moisture. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, this application provides a laminar flow adjustable circulating air drying room.

[0006] This application provides a laminar flow adjustable circulating air drying chamber, which adopts the following technical solution: A laminar flow adjustable circulating air-guided drying chamber includes a floor, a drying chamber body, a drying air guide assembly, a first adjustment assembly, a second adjustment assembly, and an isolation assembly. The floor is horizontally arranged and has a guide rail embedded at its top. A flatbed cart is mounted on the floor, and the wheels of the flatbed cart are located within the guide rail. The drying chamber body is located on the floor and has an opening on the side near the flatbed cart. A controller is installed on one side of the drying chamber body and is electrically connected to a motor on the flatbed cart. The drying air guide assembly is located within the drying chamber body and is used to blow hot air into the drying chamber body. The first adjustment assembly is located within the drying chamber body and is used to adjust the air outlet position of the drying air guide assembly. The second adjustment assembly is located within the drying chamber body and is used to adjust the air outlet direction of the drying air guide assembly. The isolation assembly is located within the drying chamber body and is used to isolate the drying chamber body.

[0007] By adopting the above technical solution, when materials need to be dried, the operator places the materials on the flatbed cart and drives the motor of the flatbed cart to work through the controller. The flatbed cart moves along the guide rail into the drying chamber. The isolation component closes to seal the drying chamber. The drying air guide component blows hot air into the drying chamber. The first adjustment component adjusts the air outlet position, and the second adjustment component adjusts the air outlet direction, so that the hot air is evenly distributed in the drying chamber. The heat received by the materials in different positions is consistent with the air volume, avoiding the situation of some materials being over-dried or not dried thoroughly.

[0008] Optionally, the drying air guide assembly includes a fan, a heater, a rotating partition, two sets of mounting boxes, and two sets of connecting pipes; a hot air chamber is opened at the top of the drying chamber body, and an air inlet pipe is connected to the top of the hot air chamber. The end of the air inlet pipe away from the hot air chamber is connected to the outside. An exhaust port is opened at the top of the drying chamber body; the fan is installed inside the air inlet pipe and is electrically connected to the controller; the heater is installed inside the air inlet pipe and is electrically connected to the controller; the rotating partition is located inside the exhaust port, and one side rotates with the drying chamber body. The rotating partition is equipped with a torsion spring at its bottom end, and the two ends of the torsion spring are fixedly connected to the rotating partition and the drying chamber body, respectively. Two sets of mounting boxes are fixed on both sides of the drying chamber body. A transfer pipe is connected to one side of each mounting box, and a corrugated pipe is connected to the transfer pipe. The corrugated pipe is vertically arranged, and an air outlet nozzle is connected to the end away from the transfer pipe. Two sets of connecting pipes are located on both sides of the drying chamber body and correspond one-to-one with the two sets of mounting boxes. The two ends of each connecting pipe are connected to the mounting box and the hot air chamber, respectively.

[0009] By adopting the above technical solution, during use, the operator controls the fan and heater through the controller. The fan draws outside air into the air inlet pipe, and the heater heats the air. The heated air enters the hot air chamber and is then transported to the mounting boxes on both sides through the connecting pipe. The hot air in the mounting box is blown towards the material from the air outlet nozzle through the transfer pipe and corrugated pipe, realizing hot air blowing. When the air pressure inside the drying chamber is too high, the hot air will push open the rotating partition and be discharged from the exhaust port, and the torsion spring is in a stretched state. When the air pressure returns to normal, the torsion spring resets, and the torsion spring drives the rotating partition to reset, and the rotating partition closes the exhaust port, so that the air pressure inside the drying chamber is always in a stable state.

[0010] Optionally, each set of the mounting box has multiple transfer pipes, corrugated pipes, and air outlet nozzles spaced apart along the length of the mounting box.

[0011] By adopting the above technical solution, multiple transfer pipes, corrugated pipes and air outlet nozzles are distributed along the length of the installation box, so that multiple air outlets are formed on both sides of the drying chamber body. Hot air is blown out from multiple air outlet nozzles at the same time, covering different areas inside the drying chamber body, avoiding the problem of hot air concentration caused by a single air outlet, and further improving the uniformity of hot air distribution.

[0012] Optionally, the first adjustment component is provided in two sets, corresponding one-to-one with the two sets of mounting boxes. The first adjustment component includes a mounting plate, a drive motor, a reciprocating screw, a drive block, and a connecting rod. The mounting plate is fixedly disposed on one side of the mounting box. The drive motor is mounted on the mounting plate and electrically connected to the controller. The reciprocating screw is rotatably disposed on the mounting plate and fixedly connected to the output shaft of the drive motor. The drive block is slidably disposed on one side of the mounting box and threadedly connected to the reciprocating screw. The connecting rod is fixedly disposed on the drive block and fixedly connected to the air outlet nozzle.

[0013] By adopting the above technical solution, when the operator drives the fan to start through the controller, the operator drives the drive motor to work synchronously through the controller. The drive motor drives the reciprocating screw to rotate, and the reciprocating screw drives the drive block to slide back and forth in the vertical direction. The drive block drives the air outlet nozzle to move synchronously through the connecting rod. The corrugated pipe extends and retracts to adapt to the change in position, making the air outlet position of the air outlet nozzle easy to adjust, thereby making the air outlet layer height of the equipment easy to adjust.

[0014] Optionally, the second adjustment component is provided in two sets, corresponding one-to-one with the two sets of connecting pipes. The second adjustment component includes a rotating plate and an isolation telescopic rod. The rotating plate is located inside the connecting pipe and is rotatably connected to the connecting pipe on one side. The fixed end of the isolation telescopic rod is fixedly disposed on the connecting pipe and is located on the rotating shaft of the connecting pipe near the rotating plate. The extension and retraction states of the two sets of isolation telescopic rods are opposite, and the movable end of one set of isolation telescopic rods abuts against the side of the rotating plate near the mounting box.

[0015] By adopting the above technical solution, during use, the operator drives the movable ends of the two sets of insulating telescopic rods to extend and retract. When the movable ends of the insulating telescopic rods are in the extended state, they abut against the side wall of the rotating plate, and the connecting pipe is in a unidirectional flow state, making it difficult for hot air in the connecting pipe to flow into the installation box. When the movable ends of the insulating telescopic rods are in the retracted state, they are disconnected from the rotating plate, and the connecting pipe is in a bidirectional flow state, making it easy for hot air in the connecting pipe to flow into the installation box. Because the extension and retraction states of the movable ends of the two sets of insulating telescopic rods are opposite, the air outlet nozzles on the two sets of installation boxes form alternating air outlets, making it easy to adjust the air outlet direction of the drying air guide assembly.

[0016] Optionally, the second adjustment assembly further includes a first drive telescopic rod, a first flow tube, a second drive telescopic rod, and a second flow tube; the rod-side cavity of the isolating telescopic rod is filled with liquid; the first drive telescopic rod is vertically arranged, with its fixed end fixedly mounted on the mounting plate, and its movable end inserted into the mounting plate; both the rodless cavity and the rod-side cavity of the first drive telescopic rod are filled with liquid; the two ends of the first flow tube are respectively connected to the rodless cavity of the first drive telescopic rod and the rod-side cavity of the isolating telescopic rod, and an overflow valve is installed on the first flow tube; the second drive telescopic rod is vertically arranged, with its fixed end fixedly mounted on the mounting box, and the rod-side cavity of the second drive telescopic rod is filled with liquid; the two ends of the second flow tube are respectively connected to the rod-side cavity of the first drive telescopic rod and the rod-side cavity of the second drive telescopic rod.

[0017] By adopting the above technical solution, when the drive block slides upward to abut against the movable end of the first drive telescopic rod, the drive block squeezes the movable end of the first drive telescopic rod, causing the movable end of the first drive telescopic rod to contract. The volume of the rodless cavity of the first drive telescopic rod decreases, and the liquid in the rodless cavity flows into the rod cavity of the isolation telescopic rod, increasing the volume of the rod cavity. The movable end of the isolation telescopic rod is in an extended state. Simultaneously, the volume of the rod cavity of the first drive telescopic rod increases, creating a negative pressure within the rod cavity. Liquid from the rod cavity of the second drive telescopic rod flows into the rod cavity of the first drive telescopic rod, and the movable end of the second drive telescopic rod is in an extended state. When the drive block slides downward, the downward force of gravity on the movable end of the first drive telescopic rod is less than the pressure of the overflow valve, causing... The movable end of the first drive telescopic rod is not easily reset; when the drive block slides down to the movable end of the second drive telescopic rod, the drive block squeezes the movable end of the second drive telescopic rod, the movable end of the second drive telescopic rod contracts, the volume of the rod cavity of the second drive telescopic rod increases, a negative pressure is formed in the rod cavity of the second drive telescopic rod, the negative pressure in the rod cavity of the second drive telescopic rod is greater than the pressure of the overflow valve, the liquid in the rod cavity of the telescopic rod is isolated from flowing back to the rodless cavity of the first drive telescopic rod, and the liquid in the rod cavity of the first drive telescopic rod flows back to the rod cavity of the second drive telescopic rod, making the rotating plate in the connecting pipe easy to be unidirectionally limited; at the same time, the first drive telescopic rod, the second drive telescopic rod and the drive block in the second adjustment assembly on the other side slide in opposite directions, so that the extension and retraction states of the movable ends of the two sets of isolated telescopic rods are opposite.

[0018] Optionally, the isolation assembly includes a fixed rod, a first electric telescopic rod, a first isolation door, a second electric telescopic rod, and a second isolation door; the opening of the drying chamber body is provided with a first receiving groove and a second receiving groove; the fixed rod is located inside the drying chamber body and is fixedly connected to the floor, and a touch switch is installed at one end of the fixed rod, the touch switch being electrically connected to the controller; the first electric telescopic rod is horizontally arranged in the first receiving groove, and its fixed end is fixedly connected to the drying chamber body; the first isolation door is located in the first receiving groove and is slidably connected to the drying chamber body, a first storage groove is provided on one side of the first isolation door, the movable end of the first electric telescopic rod is located in the first storage groove, and the movable end is fixedly connected to the first isolation door; the second electric telescopic rod is horizontally arranged in the second receiving groove, and its fixed end is fixedly connected to the drying chamber body; the second isolation door is located in the second receiving groove and is slidably connected to the drying chamber body, a second storage groove is provided on one side of the second isolation door, the movable end of the second electric telescopic rod is located in the second storage groove, and the movable end is fixedly connected to the second isolation door.

[0019] By adopting the above technical solution, when the operator drives the flatbed cart to move through the controller, the flatbed cart enters the drying chamber body along the guide rail and touches the touch switch on the fixed rod. The touch switch sends a signal to the controller, and the controller controls the motor on the flatbed cart to stop working. At the same time, it drives the movable ends of the first electric telescopic rod and the second electric telescopic rod to extend synchronously. The first electric telescopic rod and the second electric telescopic rod respectively drive the first isolation door and the second isolation door to slide out from the first receiving groove and the second receiving groove. The first isolation door and the second isolation door close the opening of the drying chamber body, realizing the sealing and isolation of the drying chamber body.

[0020] Optionally, a first sealing plate is fixedly provided on one side of the first isolation door, and a first rubber pad is fixedly provided on the side of the first sealing plate away from the first isolation door; a second sealing plate is fixedly provided on one side of the second isolation door, and a second rubber pad is fixedly provided on the side of the second sealing plate away from the second isolation door.

[0021] By adopting the above technical solution, when the first isolation door and the second isolation door are closed, the first sealing plate and the second sealing plate are in contact with each other, and the rubber gasket undergoes elastic deformation, which further enhances the sealing performance of the drying chamber body and reduces the leakage of hot air inside the drying chamber body.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up drying air guide components, hot air can be easily blown into the drying room; 2. By setting the first adjustment component and the second adjustment component, the air outlet position and air outlet direction of the drying air guide component can be easily adjusted.

[0027] When materials need to be dried, the operator places the materials on the flatbed cart 12 and drives the motor of the flatbed cart 12 to work through the controller 21. The flatbed cart 12 moves along the guide rail 11 into the drying chamber body 2. The isolation component 6 closes to seal the drying chamber body 2. The drying air guide component 3 blows hot air into the drying chamber body 2. The first adjustment component 4 adjusts the air outlet position and the second adjustment component 5 adjusts the air outlet direction.

The heated air enters the hot air chamber 22 and is then transported to the mounting boxes 34 on both sides through the connecting pipe 35. The hot air in the mounting box 34 is blown towards the material from the air outlet nozzle 343 through the transfer pipe 341 and the corrugated pipe 342, realizing hot air blowing. When the air pressure in the drying chamber body 2 is too high, the hot air will push open the rotating partition 33 and be discharged from the exhaust port 24, and the torsion spring 331 is in a stretched state. When the air pressure returns to normal, the torsion spring 331 returns to its original position, and the torsion spring 331 drives the rotating partition 33 to return to its original position, and the rotating partition 33 closes the exhaust port 24.

[0033] Reference Figure 2 and Figure 5 The first adjustment component 4 has two sets, each corresponding to one of the two mounting boxes 34. The first adjustment component 4 includes a mounting plate 41, a drive motor 42, a reciprocating screw 43, a drive block 44, and a connecting rod 45.

The drive motor 42 is mounted on the mounting plate 41 and electrically connected to the controller 21. The reciprocating screw 43 is vertically positioned below the mounting plate 41 and is rotatably connected to the mounting plate 41. One end of the reciprocating screw 43 is fixedly connected to the output shaft of the drive motor 42. The drive block 44 is located on one side of the mounting box 34 and is rectangular in shape.

The second adjusting assembly 5 includes a rotating plate 51, an isolating telescopic rod 52, a first driving telescopic rod 53, a first flow pipe 54, a second driving telescopic rod 55, and a second flow pipe 56. The rotating plate 51 is located inside the connecting pipe 35 and is rotatably connected to it on one side. The rotating plate 51 is rectangular. The isolating telescopic rod 52 is horizontally positioned below the rotating plate 51, with its fixed end fixed to the connecting pipe 35. The isolating telescopic rod 52 is located on the connecting pipe 35 near the rotation axis of the rotating plate 51. The extension and retraction states of the two sets of isolating telescopic rods 52 are opposite. The movable end of one set of isolating telescopic rods 52 abuts against the side of the rotating plate 51 near the mounting box 34. The rod cavity of the isolating telescopic rod 52 is filled with liquid.

[0035] Reference Figure 5 and Figure 6The first drive telescopic rod 53 is vertically arranged, with its fixed end fixedly mounted on the mounting plate 41. The movable end of the first drive telescopic rod 53 is inserted into the mounting plate 41. Both the rodless cavity and the rod cavity of the first drive telescopic rod 53 are filled with liquid. The first flow tube 54 is circular, with its two ends communicating with the rodless cavity of the first drive telescopic rod 53 and the rod cavity of the isolating telescopic rod 52, respectively. An overflow valve 541 is installed on the first flow tube 54. The second drive telescopic rod 55 is vertically arranged, with its fixed end fixedly mounted on the mounting box 34. The rod cavity of the second drive telescopic rod 55 is filled with liquid. The second flow tube 56 is circular, with its two ends communicating with the rod cavity of the first drive telescopic rod 53 and the rod cavity of the second drive telescopic rod 55, respectively.

[0036] When the operator starts the fan 31 through the controller 21, the operator also drives the drive motor 42 to work synchronously through the controller 21. The drive motor 42 drives the reciprocating screw 43 to rotate, and the reciprocating screw 43 drives the drive block 44 to slide back and forth in the vertical direction. The drive block 44 drives the air outlet nozzle 343 to move synchronously through the connecting rod 45.

[0037] When the drive block 44 slides upward to abut against the movable end of the first drive telescopic rod 53, the drive block 44 squeezes the movable end of the first drive telescopic rod 53, the movable end of the first drive telescopic rod 53 contracts, the volume of the rodless cavity of the first drive telescopic rod 53 decreases, the liquid in the rodless cavity of the first drive telescopic rod 53 flows into the rod cavity of the isolation telescopic rod 52, the volume of the rod cavity of the isolation telescopic rod 52 increases, the movable end of the isolation telescopic rod 52 is in an extended state, at the same time the volume of the rod cavity of the first drive telescopic rod 53 increases, a negative pressure is generated in the rod cavity of the first drive telescopic rod 53, the liquid in the rod cavity of the second drive telescopic rod 55 flows into the rod cavity of the first drive telescopic rod 53, and the movable end of the second drive telescopic rod 55 is in an extended state.

[0038] When the drive block 44 slides downward, the downward force of gravity on the movable end of the first drive telescopic rod 53 is less than the pressure of the overflow valve 541. When the drive block 44 slides downward to the movable end of the second drive telescopic rod 55, the drive block 44 presses against the movable end of the second drive telescopic rod 55, causing the movable end of the second drive telescopic rod 55 to contract. The volume of the rod cavity of the second drive telescopic rod 55 increases, creating a negative pressure inside the rod cavity. This negative pressure is greater than the pressure of the overflow valve 541, preventing the liquid in the rod cavity of the isolation telescopic rod 52 from flowing back to the rodless cavity of the first drive telescopic rod 53. The liquid in the rod cavity of the first drive telescopic rod 53 flows back to the rod cavity of the second drive telescopic rod 55, and the rotating plate 51 in the connecting pipe 35 is unidirectionally limited. Simultaneously, the first drive telescopic rod 53, the second drive telescopic rod 55, and the drive block 44 in the second adjusting assembly 5 on the other side slide in opposite directions, and the extension and retraction states of the movable ends of the two sets of isolation telescopic rods 52 are opposite.

The movable end of the first electric telescopic rod 62 is located in the first storage groove 631 and is fixedly connected to the first isolation door 63.

A first rubber pad 633 is fixedly provided on the side of the first sealing plate 632 away from the first isolation door 63.

[0041] Reference Figure 4 and Figure 7 The second electric telescopic rod 64 is horizontally positioned within the second receiving groove 26, and its fixed end is fixedly connected to the drying chamber body 2. The second isolation door 65 is vertically positioned within the second receiving groove 26 and is slidably connected to the drying chamber body 2 along the length of the second isolation door 65.

[0042] When the operator drives the flatbed trolley 12 to move via the controller 21, the flatbed trolley 12 enters the drying chamber body 2 along the guide rail 11 and touches the touch switch 611 on the fixed rod 61. The touch switch 611 sends a signal to the controller 21, and the controller 21 controls the motor on the flatbed trolley 12 to stop working. At the same time, it drives the movable ends of the first electric telescopic rod 62 and the second electric telescopic rod 64 to extend synchronously. The first electric telescopic rod 62 and the second electric telescopic rod 64 respectively drive the first isolation door 63 and the second isolation door 65 to slide out from the first receiving groove 25 and the second receiving groove 26. The first isolation door 63 and the second isolation door 65 close the opening of the drying chamber body 2.

[0043] The implementation principle of a laminar flow adjustable circulating air drying room according to an embodiment of this application is as follows: When materials need to be dried, the operator places the materials on the flatbed cart 12 and simultaneously drives the motor of the flatbed cart 12 to work through the controller 21. The flatbed cart 12 enters the drying chamber body 2 along the guide rail 11 and touches the touch switch 611 on the fixed rod 61. The touch switch 611 sends a signal to the controller 21, and the controller 21 controls the motor on the flatbed cart 12 to stop working. At the same time, it drives the movable ends of the first electric telescopic rod 62 and the second electric telescopic rod 64 to extend synchronously. The first electric telescopic rod 62 and the second electric telescopic rod 64 respectively drive the first isolation door 63 and the second isolation door 65 to slide out from the first receiving groove 25 and the second receiving groove 26. The first isolation door 63 and the second isolation door 65 close the opening of the drying chamber body 2.

[0044] When the first isolation door 63 and the second isolation door 65 close the opening of the drying chamber body 2, the operator controls the fan 31 and the heater 32 to work through the controller 21. The fan 31 draws outside air into the air inlet pipe 23, and the heater 32 heats the air. The heated air enters the hot air chamber 22 and is then transported to the mounting boxes 34 on both sides through the connecting pipe 35. The hot air in the mounting box 34 is blown towards the material from the air outlet nozzle 343 through the transfer pipe 341 and the corrugated pipe 342, thus realizing hot air blowing.

[0045] When the operator starts the fan 31 through the controller 21, the operator also drives the drive motor 42 to work synchronously through the controller 21. The drive motor 42 drives the reciprocating screw 43 to rotate, and the reciprocating screw 43 drives the drive block 44 to slide back and forth in the vertical direction. The drive block 44 drives the air outlet nozzle 343 to move synchronously through the connecting rod 45.

[0046] When the drive block 44 slides upward to abut against the movable end of the first drive telescopic rod 53, the drive block 44 squeezes the movable end of the first drive telescopic rod 53, and the liquid in the rodless cavity of the first drive telescopic rod 53 flows into the rod cavity of the isolation telescopic rod 52, and the movable end of the isolation telescopic rod 52 extends. At the same time, the liquid in the rod cavity of the second drive telescopic rod 55 flows into the rod cavity of the first drive telescopic rod 53, and the movable end of the second drive telescopic rod 55 extends.

[0047] When the drive block 44 slides downward, the downward force of gravity on the movable end of the first drive telescopic rod 53 is less than the pressure of the overflow valve 541. When the drive block 44 slides downward to the movable end of the second drive telescopic rod 55, the drive block 44 presses against the movable end of the second drive telescopic rod 55. The negative pressure in the rod chamber of the second drive telescopic rod 55 is greater than the pressure of the overflow valve 541, preventing the liquid in the rod chamber of the telescopic rod 52 from flowing back to the rodless chamber of the first drive telescopic rod 53. The liquid in the rod chamber of the first drive telescopic rod 53 flows back to the rod chamber of the second drive telescopic rod 55, and the rotating plate 51 in the connecting pipe 35 is unidirectionally limited. At the same time, the first drive telescopic rod 53, the second drive telescopic rod 55, and the drive block 44 in the second adjusting assembly 5 on the other side slide in opposite directions, and the extension and retraction states of the movable ends of the two sets of telescopic rods 52 are opposite.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
