Description

Technical Field

[0001] This utility model relates to the field of printing environmental protection technology, specifically a waste cloth drying box based on a printing press. Background Technology

[0002] In order to implement the requirements of green development, promote the formation of green development mode, and increase the protection of the ecological environment, printing press factory equipment will implement a series of environmental protection treatment operations, such as the classified collection of wiping cloths or the degradable and reusable treatment of chemical pigment waste liquid, to promote the reduction of hazardous waste and minimize the generation of hazardous waste.

[0003] Cleaning printing machines requires wiping cloths, which become hazardous waste after being contaminated with alcohol and ink. The increased weight of the cloths after they become wet leads to a large amount of hazardous waste. Furthermore, the high-heat exhaust gases from printing cannot be effectively treated to meet emission standards, resulting in a waste of high-heat energy. This causes the wiping cloths to be continuously soaked in chemical alcohol, ink, solvents, and glue, increasing the weight of the waste cloths and the accumulation of hazardous waste pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waste cloth drying box based on a printing press. This solves the problem that cleaning printing presses requires wiping cloths, which become hazardous waste after being contaminated with alcohol and ink. The increased weight of the wet cloth leads to a large amount of hazardous waste, and the ineffective treatment of high-heat exhaust gases from printing results in a waste of high-heat energy. Furthermore, the continuous contamination of the wiping cloths with chemical alcohol, ink, solvents, and adhesives increases the weight of the waste cloths and the accumulation of hazardous waste pollution.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a waste cloth drying box based on a printing press, comprising a drying box device, a waste exhaust duct, a heating system, a power distribution cabinet, and a printing press body. The waste exhaust duct runs through the interior of the drying box device, and the waste exhaust duct horizontally connects to two heating systems with the drying box device connected in series at its tail end. The power distribution cabinet is electrically connected to the heating system via wires, and the power distribution cabinet is electrically connected to the printing press body via wires.

[0006] The drying oven device includes a partition plate, a bottom layer, a second layer, a third layer, a cylinder, stainless steel plates, and a top cover. The top cover is opened and closed via the cylinder and the third layer. The bottom of the third layer is connected to the second layer, and the bottom of the second layer is connected to the bottom layer. The bottom, second, and third layers are all externally welded with two or more stainless steel plates. The bottom, second, and third layers are internally fitted with two or more partition plates. The bottom layer is connected to the exhaust duct. The printing exhaust gas is the high-temperature exhaust gas emitted by the printing machine and heating system during operation. This printing exhaust gas enters the drying oven device through the exhaust duct and is then discharged to the environmental treatment facility through the exhaust duct.

[0007] The printing exhaust gas enters the drying chamber through the exhaust duct of the heating system and the printing press. The cleaning of the printing press uses wiping cloths, which become hazardous waste after being contaminated with alcohol and ink. The increased weight of the wet cloths leads to a large amount of hazardous waste. The staff can then classify and place these hazardous waste cloths in the drying chamber for drying. The high-temperature exhaust gas flows smoothly in the drying chamber, carrying away the solvents and wastewater from the waste cloths. This achieves a combined environmentally friendly heat recovery drying effect of waste cloths and exhaust gas when the exhaust gas is discharged to the environmental treatment facility.

[0008] Preferably, the bottom of the bottom layer of the box is provided with a tray, and the left and right openings of the bottom layer of the box are connected to the exhaust duct.

[0009] By fully welding the bottom of the cabinet to the tray, a strong weld is achieved, ensuring good sealing and preventing water leakage. This also makes the tray at the bottom of the cabinet provide stable protection against seepage for the drying oven device.

[0010] Preferably, the second layer of the box is provided with eight support blocks, and a rag placement layer is placed on the second layer of the box. The support blocks can serve as support points for the rag placement layer, and a layer of stainless steel mesh is welded to the surface of the rag placement layer.

[0011] By welding a layer of stainless steel mesh to the surface of the rag placement layer, and then installing at least four 304 stainless steel heavy-duty hinges between the partition plate and the stainless steel plate to assemble the entire drying oven, the eight support blocks on the second layer of the oven body can stabilize the rag placement layer, making the placement of rags or waste cloths containing solvents and inks safer and more stable.

[0012] Preferably, the partition plate divides the interior of the bottom layer and the second layer of the box into four compartments, and the stainless steel plate divides the outer frame of the bottom layer and the second layer of the box into four compartments.

[0013] By fully welding the stainless steel plates, the bottom layer and the second layer of the box are firmly welded to the stainless steel plates and the partition panels, ensuring good sealing and preventing water leakage.

[0014] Preferably, the cylinder is provided with a cylinder head and a bracket fixing seat. The cylinder head is axially connected to the piston rod of the cylinder through the bracket fixing seat. The piston rod of the cylinder is mechanically connected to the piston cylinder of the cylinder. Two bracket fixing seats are provided and are respectively horizontally inserted into the left and right sides of the second layer of the housing.

[0015] The cylinder mounting bracket is used to reinforce the second layer of the housing, making the cylinder working frame more stable on both sides of the second layer of the housing.

[0016] Preferably, there are two bracket fixing seats, which are horizontally inserted into the left and right sides of the upper cover respectively, and there are two cylinders, which are installed on the left and right sides of the upper cover respectively.

[0017] The cylinder mounting bracket is used to reinforce the top cover of the housing, making the cylinder operation more stable when pushing and pulling the top cover on both sides.

[0018] Preferably, the left and right ends of the printing press body are fixedly provided with an unwinding seat and a rewinding seat, the right side of the unwinding seat is fixedly provided with an unwinding traction roller, and the left side of the rewinding seat is fixedly provided with a rewinding traction roller.

[0019] By integrating the unwinding seat and unwinding roller on the left side and the take-up seat and take-up roller on the right side of the printing press body, a highly symmetrical production line is formed. The side-mounted exhaust duct and heating system are connected to the series circuit of the power distribution cabinet to ensure stable exhaust gas operation. The heated exhaust gas transportation improves the thermal melt biodegradable operation effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-9 This utility model provides a waste cloth drying box based on a printing press, including a drying box device 1, a waste exhaust duct 2, a heating system 3, a power distribution cabinet 4, and a printing press body 7. The waste exhaust duct 2 runs through the interior of the drying box device 1. The waste exhaust duct 2 is horizontally connected to two heating systems 3 and its tail end is connected in series with the drying box device 1. The power distribution cabinet 4 is electrically connected to the heating system 3 via wires. The power distribution cabinet 4 is also electrically connected to the printing press body 7 via wires.

[0034] Because cleaning printing machines requires wiping cloths, these cloths become hazardous waste after being contaminated with alcohol and ink. The increased weight of the cloths after they become wet leads to a large amount of hazardous waste. Furthermore, the high-heat exhaust gases from printing cannot be effectively treated to meet emission standards, resulting in a waste of high-heat energy. This causes the wiping cloths to be continuously soaked in chemical alcohol, ink, solvents, and glue, increasing the weight of the waste cloths and the accumulation of hazardous waste pollution.

[0035] The drying oven device 1 is equipped with a partition plate 11, a bottom layer 12, a second layer 13, a third layer 14, a cylinder 15, a stainless steel plate 16, and a top cover 17. The top cover 17 is opened and closed via the cylinder 15 and the third layer 14. The bottom of the third layer 14 is connected to the second layer 13, and the bottom of the second layer 13 is connected to the bottom layer 12. The bottom layer 12, the second layer 13, and the third layer 14 are externally welded with two or more stainless steel plates 16. The bottom layer 12, the second layer 13, and the third layer 14 are internally equipped with two or more partition plates 11. The bottom layer 12 is connected to the exhaust duct 2. The printing exhaust gas is the high-temperature exhaust gas discharged when the printing machine body 7 and the heating system 3 are working. The printing exhaust gas enters the drying oven device 1 through the exhaust duct 2 and is then discharged to the environmental protection treatment facility through the exhaust duct 2.

[0036] It should be noted that the printing exhaust gas enters the drying chamber device 1 through the exhaust duct 2 after passing through the heating system 3 and the printing machine body 7. The cleaning machine uses wiping cloths, which become hazardous waste after being soaked with alcohol and ink. The increased weight of the cloths after they get wet leads to a large amount of hazardous waste. The staff can then classify these hazardous waste cloths and place them in the drying chamber device 1 for a wiping cloth drying operation. This allows the high-temperature exhaust gas to flow smoothly in the drying chamber device 1, which can carry away the solvents and wastewater in the waste cloths. This achieves a combined environmentally friendly heat recovery drying effect of waste cloths and exhaust gas when the exhaust gas is discharged to the environmental protection treatment facility.

[0037] The bottom of the box body 12 is provided with a tray, and the left and right openings of the box body 12 are connected to the exhaust duct 2.

[0038] It should be noted that by fully welding the bottom layer 12 of the box to the tray, a firm weld is achieved, the seal is good, and water leakage is prevented, so that the tray of the bottom layer 12 of the box provides stable anti-seepage protection for the drying box device 1.

[0039] The second layer 13 of the box is provided with eight support blocks 131. A rag placement layer is placed on the second layer 13 of the box. The support blocks 131 can serve as support points for the rag placement layer. A layer of stainless steel mesh is welded to the surface of the rag placement layer.

[0040] It should be noted that by welding a layer of stainless steel mesh to the surface of the rag placement layer, and then installing at least four 304 stainless steel heavy-duty hinges between the partition plate 11 and the stainless steel plate 16 to assemble the entire interior of the drying oven device 1, the eight support blocks 131 of the second layer 13 of the oven body are stabilized to protect the rag placement layer, making the placement of rags or scraps containing solvents and inks safer and more stable.

[0041] The partition plate 11 divides the interior of the bottom layer 12 and the second layer 13 of the box into four compartments, and the stainless steel plate 16 divides the outer frame of the bottom layer 12 and the second layer 13 of the box into four compartments.

[0042] It should be noted that by fully welding the stainless steel plate 16, the bottom layer 12 and the second layer 13 of the box between the stainless steel plate 16 and the partition plate 11 are firmly welded, with good sealing and no water leakage.

[0043] The cylinder 15 is provided with a cylinder head 151 and a bracket fixing seat 152. The cylinder head 151 is axially connected to the piston rod of the cylinder 15 through the bracket fixing seat 152. The piston rod of the cylinder 15 is mechanically connected to the piston cylinder of the cylinder 15. There are two bracket fixing seats 152, which are horizontally inserted into the left and right sides of the second layer 13 of the housing respectively.

[0044] It should be noted that the cylinder 15 mounting bracket 152 is used to reinforce the second layer 13 of the housing separately, making the cylinder 15 working frame more stable on both sides of the second layer 13 of the housing.

[0045] Two bracket fixing seats 152 are provided and are horizontally inserted into the left and right sides of the upper cover 17 respectively. Two cylinders 15 are provided and are installed on the left and right sides of the upper cover 17 respectively.

[0046] It should be noted that the upper cover 17 of the housing is reinforced separately by the bracket fixing seat 152 at the mounting point of the cylinder 15, which makes the operation of the cylinder 15 pushing and pulling to open and close both sides of the upper cover 17 more stable.

[0047] The printing press body 7 is fixedly provided with an unwinding seat 5 and a rewinding seat 9 at its left and right ends. An unwinding traction roller 6 is fixedly provided on the right side of the unwinding seat 5, and a rewinding traction roller 8 is fixedly provided on the left side of the rewinding seat 9.

[0048] It should be noted that by integrating the unwinding seat 5 and unwinding traction roller 6 on the left side and the take-up seat 9 and take-up traction roller 8 on the right side through the printing machine body 7, a highly symmetrical production line is formed. The exhaust duct 2 is installed on the side, the heating system 3 is connected to the power distribution cabinet 4 in series circuit, the exhaust gas is stable, and the heated exhaust gas transportation improves the thermal melt biodegradable operation effect.

[0049] It should be noted that the airflow inside the drying chamber device 1 must cover the waste cloth inside the chamber; the volume of the drying chamber device 1 should be designed according to the installation space of the site so that the exhaust gas passes through the waste cloth four times, and the heat in the exhaust gas discharged by the printing press body 7 should be utilized as much as possible to achieve the purpose of energy saving.

[0050] It should be noted that the internal structure of the drying box device 1 must ensure that the exhaust airflow is unobstructed and can carry away the solvent and wastewater in the waste cloth. Therefore, the box body is arranged in layers: bottom layer 12, second layer 13, and third layer 14. Then, the space on the top cover 17 of the box body needs to be reserved at 300mm to prevent the airflow from being obstructed when the waste cloth is piled up too high. The middle part uses stainless steel wire mesh to ensure that hot air can enter the waste cloth.

[0051] It should be noted that the body structure of the drying oven device 1 is made of hot-dip galvanized pipe and is sealed with stainless steel plate 16 on all sides; the bottom of the bottom layer 12 of the body has a leak-proof tray to collect the solvent and ink dripped from the waste cloth for easy cleaning.

[0052] It should be noted that the opening and closing of the drying oven 1 shall be achieved by using a pneumatic cylinder 15, with a locking device cylinder head 151 and bracket fixing seat 152 to prevent personnel injury due to misoperation; the bottom layer 12, the second layer 13, and the third layer 14 of the oven body, together with the top cover 17, have good sealing performance to reduce the leakage of exhaust gas and cause fugitive emissions; the bottom layer 12 of the oven body must be grounded to reduce the risk of fire caused by static electricity.

[0053] It should be noted that connecting the exhaust duct 2 of the printing press body 7 to the drying chamber device 1 should not affect the exhaust air volume of the printing press body 7, so as to avoid causing the finished product to exceed the VOC standard.

[0054] Please see Figures 1-9 This utility model provides a waste cloth drying box based on a printing press, including a drying box device 1, a waste exhaust duct 2, a heating system 3, a power distribution cabinet 4, and a printing press body 7. The waste exhaust duct 2 runs through the interior of the drying box device 1. The waste exhaust duct 2 is horizontally connected to two heating systems 3 and its tail end is connected in series with the drying box device 1. The power distribution cabinet 4 is electrically connected to the heating system 3 via wires. The power distribution cabinet 4 is also electrically connected to the printing press body 7 via wires.

[0055] The drying oven device 1 is equipped with a partition plate 11, a bottom layer 12, a second layer 13, a third layer 14, a cylinder 15, a stainless steel plate 16, and a top cover 17. The top cover 17 is opened and closed via the cylinder 15 and the third layer 14. The bottom of the third layer 14 is connected to the second layer 13, and the bottom of the second layer 13 is connected to the bottom layer 12. The bottom layer 12, the second layer 13, and the third layer 14 are externally welded with two or more stainless steel plates 16. The bottom layer 12, the second layer 13, and the third layer 14 are internally equipped with two or more partition plates 11. The bottom layer 12 is connected to the exhaust duct 2. The printing exhaust gas is the high-temperature exhaust gas discharged when the printing machine body 7 and the heating system 3 are working. The printing exhaust gas enters the drying oven device 1 through the exhaust duct 2 and is then discharged to the environmental protection treatment facility through the exhaust duct 2.

[0056] It should be noted that the printing exhaust gas enters the drying chamber device 1 through the exhaust duct 2 after passing through the heating system 3 and the printing machine body 7. The cleaning machine uses wiping cloths, which become hazardous waste after being soaked with alcohol and ink. The increased weight of the cloths after wetting leads to a large amount of hazardous waste. The staff can then classify these hazardous waste cloths and place them in the drying chamber device 1 for a wiping cloth drying operation. This allows the high-temperature exhaust gas to flow smoothly in the drying chamber device 1, carrying away the solvents and wastewater from the waste cloths. This achieves a combined environmental pretreatment and degradation effect of waste cloths and exhaust gas when the exhaust gas is discharged to the environmental protection treatment facility.

[0057] The bottom of the box body 12 is provided with a tray, and the left and right openings of the box body 12 are connected to the exhaust duct 2.

[0058] It should be noted that by fully welding the bottom layer 12 of the box to the tray, a firm weld is achieved, the seal is good, and water leakage is prevented, so that the tray of the bottom layer 12 of the box provides stable anti-seepage protection for the drying box device 1.

[0059] The second layer 13 of the box is provided with eight support blocks 131. A rag placement layer is placed on the second layer 13 of the box. The support blocks 131 can serve as support points for the rag placement layer. A layer of stainless steel mesh is welded to the surface of the rag placement layer.

[0060] It should be noted that by welding a layer of stainless steel mesh to the surface of the rag placement layer, and then installing at least four 304 stainless steel heavy-duty hinges between the partition plate 11 and the stainless steel plate 16 to assemble the entire interior of the drying oven device 1, the eight support blocks 131 of the second layer 13 of the oven body are stabilized to protect the rag placement layer, making the placement of rags or scraps containing solvents and inks safer and more stable.

[0061] The partition plate 11 divides the interior of the bottom layer 12 and the second layer 13 of the box into four compartments, and the stainless steel plate 16 divides the outer frame of the bottom layer 12 and the second layer 13 of the box into four compartments.

[0062] It should be noted that by fully welding the stainless steel plate 16, the bottom layer 12 and the second layer 13 of the box between the stainless steel plate 16 and the partition plate 11 are firmly welded, with good sealing and no water leakage.

[0063] It should be noted that the machine operators of each printing press 7 promptly pour the waste cloth from wiping the machine into the drying box device 1; the cleaners promptly collect, weigh, and store the dried waste cloth, thereby achieving an energy-saving operation effect of orderly waste cloth drying for the heat recovery and feedback utilization of the printing press 7. In addition, the waste cloth drying itself flows smoothly through the high-temperature exhaust gas drying box device 1, which can remove solvents and wastewater from the waste cloth, effectively purifying the hazardous waste concentration of the waste cloth and reducing the weight of the waste cloth itself.

Furthermore, the use of the printing press body 7 to dry the wiping cloths reduces the amount of hazardous waste and achieves the goal of reducing the weight of the waste cloths.
