Description

Technical Field

[0001] The invention relates to the technical field of drying rooms, in particular to a paper roll drying room. Background Art

[0002] Fireworks paper tube drying room is a device specially used for drying fireworks paper tubes. It can provide a uniform and suitable temperature and humidity environment for the paper tubes to ensure that the paper tubes reach the ideal degree of dryness during the drying process. The drying room is usually equipped with a heating system, air circulation system, temperature control system, etc. These systems work together to evaporate the moisture inside and on the surface of the paper tube by delivering hot air or dry air, thereby achieving a drying effect.

DETAILED DESCRIPTION

[0049] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] Embodiment 1, as Figures 1 to 19As shown, the paper tube drying room proposed by the present invention includes a frame 1, on which a heat pump system 2 and a paper tube placement system 3 are installed. The heat pump system includes two high-speed fans 201, an evaporator 202, a dehumidifier 203 and a condenser 204 fixedly installed on the frame 1, and also includes a liquid storage tank 205, a gas-liquid separator 206 and a compressor 207 fixedly installed on the frame 1. Two exhaust ducts 208 are fixedly installed on the frame 1, the outlet of the compressor 207 is connected to the condenser 204, the outlet of the condenser 204 is connected to the expansion valve or the capillary tube, the other end of the expansion valve or the capillary tube is connected to the evaporator 202 and the dehumidifier 203, and the outlets of the evaporator 202 and the dehumidifier 203 are connected back to the compressor 207 to form a closed circulation system.

[0051] The compressor 207 sucks in low-temperature and low-pressure refrigerant gas, and the compressor 207 compresses the refrigerant gas into high-temperature and high-pressure gas, and then transports it to the condenser 204. The high-temperature and high-pressure refrigerant gas releases heat in the condenser 204, and the gas passing through the condenser 204 will be heated. The heated gas will enter the paper tube placement system 3 to dry the paper tube 9. The refrigerant gas is cooled and condensed into liquid in the condenser 204. The liquid refrigerant flows to the evaporator 202 and the dehumidifier 203 through the expansion valve or the capillary tube. The refrigerant absorbs heat in the evaporator 202 and the dehumidifier 203, and then the gas passing through the evaporator 202 and the dehumidifier 203 can be cooled, and then the water vapor in the gas can be condensed to discharge the water in the gas, so that the gas after contacting the paper tube 9 can be dehumidified. The liquid storage tank 205 is used to store the refrigerant liquid to balance the refrigerant pressure in the system. Before the refrigerant enters the compressor 207 , the liquid refrigerant and the gaseous refrigerant are separated by the gas-liquid separator 206 to ensure that the compressor 207 sucks in the liquid refrigerant.

[0052] Furthermore, the paper tube placement system includes a drying box 301 fixedly mounted on a frame, and a plurality of drying chambers 302 are separated in the drying box 301. The paper tube placement system 3 also includes a scaling fastening component installed in the drying chamber 302, and a plurality of support rods 5 are installed on the scaling fastening component. The support rods 5 are used to insert into the paper tube 9 and position the paper tube 9. Two groups of fastening components for fixing the paper tube 9 are installed on the support rods 5, and paper tubes with different inner diameters can be fixed by the fastening components. The scaling fastening component equidistantly and synchronously adjusts the distance between two adjacent support rods 5, and the paper tubes stacked together can be quickly dispersed by the scaling fastening component. The scaling fastening component also includes a fastening drive mechanism, and the fastening drive mechanism controls the two groups of fastening components to periodically fix the paper tube 9. When the fastening assembly fixes the paper tube 9, it needs to contact the paper tube 9, so that the position where the paper tube 9 and the fastening assembly contact cannot directly contact the gas, thereby reducing the dehumidification effect of this position. By using two groups of fastening assemblies to fix the paper tube 9 alternately, each position of the paper tube 9 can effectively be in direct contact with the gas, which can effectively improve the overall drying effect and efficiency of the paper tube 9.

[0053] In this embodiment, a gas path system for conveying gas is also installed in the drying chamber 302. The gas path system includes a door 303 rotatably installed on the drying chamber 302, and an air inlet joint 304 is fixedly installed on the door 303. The heated gas after passing through the condenser 204 will enter the inside of the air inlet joint 304. A gas plate 305 is fixedly installed on the door 303, and a plurality of exhaust holes 306 are provided on the gas plate 305. The heated gas will enter the inside of the drying chamber 302 through the exhaust holes 306, so that the hot gas can contact the paper tube 9, thereby drying the paper tube 9. A valve should be provided on the air inlet joint 304. By controlling the opening and closing of the valve, it is possible to control whether the drying chamber 302 is used, and then the number of drying chambers 302 used can be effectively controlled according to production needs. A guide plate 307 is fixedly installed in the drying chamber 302, and a plurality of air suction holes 308 are provided on the guide plate 307. The zoom fastening component is located between the gas plate 305 and the guide plate 307. The gas that contacts the paper tube 9 will take away the moisture on the paper tube 9 and re-enter the heat pump system 2 through the guide plate 307. The heat pump system 2 can dehumidify and heat the gas.

[0054] Furthermore, the zoom fastening component includes a base block 4 fixedly installed in the drying chamber 302 and a plurality of sliders 401 sliding in the drying chamber 302, the plurality of sliders 401 are arranged in a linear array and are spread out in the transverse and longitudinal directions of the base block 4, the plurality of sliders 401 and the base block 4 form a rectangle, a plurality of first connecting rods 402 are fixedly installed on the base block 4 and the sliders 401, two adjacent first connecting rods 402 are slidably connected by a first connecting sleeve 403, and two of the adjacent first connecting rods 402 are located in the rectangle formed by the sliders 401 and the base block 4. Two first connecting rods 404 are rotatably installed on multiple sliders 401 on adjacent sides and the base block 4, and connecting blocks 405 are rotatably installed on two adjacent first connecting rods 404. Two adjustment plates 406 are slidably installed in the drying chamber 302, and the connecting blocks 405 are rotatably connected to the adjustment plates 406. Two first push rod motors 407 are fixedly installed in the drying chamber 302, and the two first push rod motors 407 correspond one-to-one to the adjustment plates 406, and the output shafts of the first push rod motors 407 are fixedly connected to the adjustment plates 406. The first push rod motor 407 can be used to drive the adjustment plate 406 to move up and down, thereby driving the connecting block 405 to slide on the adjustment plate 406 and driving the first connecting rod 404 to rotate. The first push rod motor 407 can be used to drive the adjustment plate 406 to rise or fall and drive the multiple sliders 401 to shrink or expand toward the base block 4. When installing the paper tube 9, it is necessary to shrink the multiple sliders 401. After the installation of the paper tube 9, the multiple sliders 401 can be expanded outward to drive the paper tube 9 to expand, thereby quickly dispersing the paper tube 9 to prevent two adjacent paper tubes 9 from contacting each other, thereby effectively increasing the contact area between the paper tube 9 and the gas, thereby effectively improving the drying efficiency and quality of the paper tube 9.

[0055] The support rod 5 is fixedly mounted on the base block 4 and the slider 401, a first push rod 501 is slidably mounted in the support rod 5, a second push rod 502 is slidably mounted in the first push rod 501, a plurality of second connecting rods 503 are fixedly mounted on the first push rod 501, two adjacent second connecting rods 503 are slidably connected via a second sliding sleeve 504, a plurality of third connecting rods 505 are fixedly mounted on the second push rod 502, two adjacent third connecting rods 505 are slidably connected via a third sliding sleeve 506. By inserting the support rod 5 into the paper tube 9, the paper tube 9 can be fixed, so that the paper tube 9 can be approached and expanded.

[0056] In this embodiment, a group of fastening components includes a connecting column 507 fixedly mounted on the support rod 5, and multiple groups of transmission rods are rotatably mounted on the connecting column 507. One group of transmission rods includes two rotating rods 508, and a support plate 509 is rotatably mounted on one group of transmission rods. A driving sleeve 510 is slidably mounted on both ends of the support rod 5, and multiple driving strips 511 are rotatably mounted on the driving sleeve 510. The multiple driving strips 511 are rotatably connected with the transmission rods one by one. Two driving sleeves 510 in one group of fastening components are fixedly connected with the first push rod 501, and two driving sleeves 510 in another group of fastening components are fixedly connected with the second push rod 502. When the first push rod 501 or the second push rod 502 drives the driving sleeve 510 to move, it will drive the driving strip 511 to rotate, and the rotating driving strip 511 will drive the two rotating rods 508 to rotate synchronously, and the rotating rotating rod 508 will drive the support plate 509 to expand or contract, so that the multiple expanded support plates 509 can fix the paper tube 9. By periodically driving the first push rod 501 and the second push rod 502 to move, the two sets of fastening components can periodically fix the paper tube 9, thereby ensuring that each position of the paper tube 9 can contact with the gas.

[0057] Among them, the fastening drive mechanism includes a transmission tube 6 fixedly installed on one of the second sliding sleeves 504 and the third sliding sleeve 506, a push plate 602 is fixedly installed on the transmission tube 6, a vertical plate 603 is fixedly installed in the drying chamber 302, two round rods 604 are slidably installed on the vertical plate 603, and the round rods 604 are slidably connected with the push plates 602 in a one-to-one correspondence, two bases 601 are fixedly installed in the drying chamber 302, an eccentric block 605 is rotatably installed on the base 601, an adjusting block 606 is slidably installed on the eccentric block 605, a driving plate 607 is rotatably installed on the adjusting block 606, the two driving plates 607 are rotatably connected with the round rods 604 in a one-to-one correspondence, a first motor 608 is fixedly installed on the eccentric block 605, a screw rod 609 is rotatably installed in the eccentric block 605, the screw rod 609 is threadedly connected to the adjusting block 606, and the output shaft of the first motor 608 is fixedly connected to the screw rod 609. When the eccentric block 605 rotates, it will drive the driving plate 607 to rotate, and the rotating driving plate 607 will be able to push the round rod 604 to move, and then through the transmission tube 6 and the transmission tube 6, the first push rod 501 and the second push rod 502 can be driven to move. For paper tubes 9 with different inner diameters, the first motor 608 can be used to drive the screw rod 609 to rotate, and the stroke of the round rod 604 can be adjusted by adjusting the position of the adjustment block 606, so that the expanded diameters of the multiple support plates 509 can adapt to paper tubes 9 with different inner diameters.

[0058] Further, a gear 610 is fixedly mounted on the eccentric block 605, a sector tooth 611 is rotatably mounted on the base 601, the sector tooth 611 meshes with the gear 610, a transmission belt 612 is fixedly mounted on the sector tooth 611, one of the pulleys of the two transmission belts 612 is fixedly connected via a transmission shaft 613, a second motor 614 is fixedly mounted in the drying chamber 302, and the output shaft of the second motor 614 is coaxially fixedly connected with the transmission shaft 613. The transmission shaft 613 is driven to rotate by the second motor 614, and then the two transmission belts 612 can be driven to rotate synchronously, and then the two sector teeth 611 can be made to rotate synchronously, when one sector tooth 611 meshes with the gear 610 for transmission, the other sector tooth 611 will not be able to mesh with the gear 610 for transmission, and then the two gears 610 can be rotated alternately, and then the two round rods 604 can move alternately, and then the first push rod 501 and the second push rod can move alternately, so that the two sets of fastening components can alternately fix the paper tube 9.

[0059] The working principle of this embodiment is: the first push rod motor 407 can drive the adjustment plate 406 to move up and down, and then drive the connecting block 405 to slide on the adjustment plate 406 and drive the first connecting rod 404 to rotate. The first push rod motor 407 can drive the adjustment plate 406 to rise or fall and drive multiple sliders 401 to shrink or expand in the direction of the base block 4. When installing the paper tube 9, it is necessary to shrink the multiple sliders 401. After the installation of the paper tube 9 is completed, the multiple sliders 401 can be expanded outward to drive the paper tube 9 to expand, and then the paper tube 9 can be quickly dispersed to prevent two adjacent paper tubes 9 from contacting each other, thereby effectively increasing the contact area between the paper tube 9 and the gas, and thereby effectively improving the drying efficiency and drying quality of the paper tube 9.

[0060] The second motor 614 drives the transmission shaft 613 to rotate, which in turn drives the two transmission belts 612 to rotate synchronously, which in turn makes the two sector teeth 611 rotate synchronously, when one sector tooth 611 meshes with the gear 610 for transmission, the other sector tooth 611 will not mesh with the gear 610 for transmission, which makes the two gears 610 rotate alternately, which makes the two round rods 604 move alternately, which makes the first push rod 501 and the second push rod move alternately, and makes the two sets of fastening components alternately fix the paper tube 9. This ensures that each position of the paper tube 9 can contact with the gas.

[0061] Embodiment 2, as Figure 1 and Figure 20 to Figure 25As shown, based on the first embodiment, an air flow distribution system is also installed on the frame 1, and the air flow distribution system is installed on the frame and located between the heat pump system 2 and the paper tube placement system 3. The air flow distribution system controls the gas flow rate inside different drying chambers 302 according to the moisture content inside different drying chambers 302. Since multiple drying chambers 302 are set, the specifications and moisture content of the paper tube 9 inside each drying chamber 302 may be different. At this time, it is necessary to increase the gas flow inside the drying chamber 302 with a high moisture content.

The air that contacts the paper tube 9 will enter the control room 704 through the air inlet connection port 705, and then enter the heat pump system 2 again through the control room 704.

[0063] The exhaust valve 702 includes a connecting pipe 7021 fixedly mounted on the air box 7, a tapered hole 7022 is provided in the connecting pipe 7021, a blocking plate 7023 is slidably mounted in the tapered hole 7022, a transmission rod 7024 is fixedly mounted on the blocking plate 7023, and a connecting head 7025 is provided on the connecting pipe 7021, and the connecting head 7025 is connected to the air inlet connector 304 in a one-to-one correspondence through the connecting pipe. The gas dehumidified and heated by the heat pump system 2 will enter the air box 7 and enter the air inlet connector 304 through the exhaust valve 702, and then by changing the effective flow area inside the multiple exhaust valves 702, that is, changing the ratio of the flow area of ​​the multiple exhaust valves 702, the amount of gas passing through the exhaust valve 702 can be controlled, and then the amount of gas entering different drying chambers 302 can be controlled. When the blocking plate 7023 moves downward, the flow area inside the connecting pipe 7021 will be increased, that is, the effective flow area of ​​the exhaust valve 702 will be increased.

[0064] In this embodiment, two rectangular plates 707 are slidably installed in the control chamber 704, and the two rectangular plates 707 are fixedly connected by a column 708. Moisture-absorbing cotton 709 is filled between the two rectangular plates 707. The transmission rod 7024 is fixedly connected to one of the rectangular plates 707. A spring 710 is fixedly installed in the control chamber 704, and the other end of the spring 710 is fixedly connected to the rectangular plate 707 at the bottom. The gas entering the control chamber 704 through the drying chamber 302 will come into contact with the hygroscopic cotton 709, and the hygroscopic cotton 709 will initially absorb the moisture inside the gas. At this time, the gravity of the hygroscopic cotton 709 will increase, thereby driving the rectangular plate 707 to descend. The descending rectangular plate 707 will drive the blocking plate 7023 to move downward, thereby increasing the effective flow area of ​​the exhaust valve 702. When the initial wind speed of the drying chamber 302 with more moisture remains the same, more moisture will be discharged per unit time, and the effective flow area of ​​different exhaust valves 702 can be adjusted according to the weight change inside different control chambers 704, so as to ensure that the air volume inside different drying chambers 302 is reasonably distributed when the output power of the high-speed fan 201 remains unchanged.

A third motor 701 is fixedly installed on the control box 703, and the output shaft of the third motor 701 is fixedly connected to the rotating shaft 711. The rotating shaft 711 can be driven to rotate by the third motor 701, and the rotating rotating shaft 711 can drive the top block 712 to rotate. When the top block 712 rotates to a vertical position, it will abut against the rectangular plate 707, so that the rectangular plate 707 cannot move downward, and the effective flow area of ​​the exhaust valve 702 cannot be adjusted, so that the gas volume inside the multiple drying chambers 302 can be kept equal.

[0066] Further, the control box 703 is fixedly mounted with a second push rod motor 8, the control box 703 is slidably mounted with a synchronous plate 801, the synchronous plate 801 is fixedly mounted with a plurality of squeezing rods 802, a squeezing plate 803 is slidably mounted between the two rectangular plates 707, the squeezing plate 803 is slidably connected with the squeezing rods 802, a drainage hole 804 is provided on the rectangular plate 707 at the bottom, a drainage pipe 805 is fixedly mounted on the control chamber 704, and the drainage hole 804 is connected with the drainage pipe 805. When the paper roll 9 inside the drying chamber 302 is replaced, it is necessary to drain the moisture inside the hygroscopic cotton so that the rectangular plate 707 returns to the initial position. At this time, the squeezing plate 803 can be driven by the second push rod motor 8 to squeeze the hygroscopic cotton 709, so that the moisture inside the hygroscopic cotton 709 can be discharged and uniformly discharged through the drainage pipe 805. It should be noted that a valve should be installed on the drainage pipe 805, which is opened when draining and closed at other times.

[0067] The working principle of this embodiment is as follows: the gas dehumidified and heated by the heat pump system 2 will enter the interior of the air box 7, and enter the interior of the air inlet joint 304 through the exhaust valve 702, and then by changing the effective flow area inside the multiple exhaust valves 702, that is, changing the ratio of the flow areas of the multiple exhaust valves 702, the amount of gas passing through the exhaust valve 702 can be controlled, and then the amount of gas entering different drying chambers 302 can be controlled. When the sealing plate 7023 moves downward, the flow area inside the connecting pipe 7021 will be increased, that is, the effective flow area of ​​the exhaust valve 702 will be increased. The gas entering the control chamber 704 through the drying chamber 302 will come into contact with the hygroscopic cotton 709, and the hygroscopic cotton 709 will initially absorb the moisture inside the gas. At this time, the gravity of the hygroscopic cotton 709 will increase, thereby driving the rectangular plate 707 to descend. The descending rectangular plate 707 will drive the blocking plate 7023 to move downward, thereby increasing the effective flow area of ​​the exhaust valve 702. When the initial wind speed of the drying chamber 302 with more moisture remains the same, more moisture will be discharged per unit time, and the effective flow area of ​​different exhaust valves 702 can be adjusted according to the weight change inside different control chambers 704, so as to ensure that the air volume inside different drying chambers 302 is reasonably distributed when the output power of the high-speed fan 201 remains unchanged.
