Description
Technical Field
[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a zero-gas-consumption drying device for a thermal power boiler. Background Technology
[0002] Products or raw materials often require drying, such as cotton or coated workpieces. To reduce carbon emissions, drying equipment is shifting from using traditional fossil fuels or coal to using clean energy sources such as solar and wind power.
[0003] A thermal electric boiler is a heating device that uses electric energy for heating. It does not consume gas or fuel oil, achieving zero gas consumption and zero emissions, making it environmentally friendly. When used for drying workpieces, it heats thermal oil and then pumps it into a drying chamber to continuously heat the workpiece, thus evaporating excess moisture.
[0004] After the workpiece is coated, it is often placed in a drying oven to dry. The drying oven is divided into several layers, and each layer is heated by heated heat transfer oil. However, the support plate corresponding to each layer of workpieces usually needs to leave an air channel to discharge water vapor in the drying oven. During the drying process, the coating on the workpiece drips and tends to accumulate, causing thickening at the edges and corners. This results in weak protection of the coated workpiece in the heat transfer oil drying chamber. To address this issue, we propose a zero-gas-consumption drying device using a thermal power boiler. Utility Model Content
[0005] The purpose of this invention is to provide a zero-gas-consumption drying device for a thermal power boiler, which can use a bowl-shaped tray to catch the paint dripping from the workpiece, thus facilitating the separation of the workpiece from the dripping paint and improving the protection of the coated workpiece within the heat transfer oil drying chamber.
[0006] The specific technical solution adopted in this utility model is as follows:
[0007] A zero-gas-consumption drying device for a thermal electric boiler includes a housing and a thermal electric boiler connected to the housing. The housing contains a drying chamber and several partitions arranged in a vertical array within the drying chamber. Each partition has a porous square plate structure, and several square pieces of cloth are arranged on the upper surface of each partition. The four corners of each square piece of cloth are folded upwards and fixed with columns. The columns are detachably connected to adjacent partitions. When drying workpieces, the square pieces of cloth and the columns at their four corners form a bowl-shaped tray. The workpiece with the coating layer is placed in the bowl-shaped tray along with a base, with the ventilation holes of the partitions staggered. The partitions are then spaced apart. Stack the parts in the drying chamber, close the door, and start the thermal boiler to pump high-temperature heat transfer oil into the chamber, transferring heat to the drying chamber so that the drying chamber can be heated to the specified range to heat the coated workpiece. If the workpiece drips paint, the bowl-shaped tray can catch the dripping paint on the workpiece. At the same time, these workpieces are supported by the base and suspended on the bowl-shaped tray, which facilitates the separation of the workpiece from the dripping paint and prevents the coating from thickening, thereby improving the protective effect of the heat transfer oil on the coated workpiece in the drying chamber. After the coating hardens, the drying is stopped, the thermal boiler is stopped, and finally the door is opened to remove these workpieces and the partition.
[0008] The lower surface of each partition is threaded with several fastening screws. The upper ends of the fastening screws all face upward and penetrate the adjacent partitions and are threaded with the lower ends of the adjacent columns. Tightening the fastening screws along the threads until they are unscrewed can separate the partitions and the corresponding columns, making it easy to disassemble the bowl-shaped tray. Conversely, tightening the fastening screws along the threads in reverse until the columns on the partitions are tightened can easily fix the bowl-shaped tray.
[0009] Two sets of load-bearing plates are distributed on both sides of the drying chamber. Several load-bearing plates in the two sets are arranged in a vertical array inside the drying chamber. Storage spaces are formed above the two opposing load-bearing plates. In this way, several storage spaces are arranged vertically at equal intervals, which makes it convenient to put the partition into different storage spaces and to easily adjust the distance between the two partitions, so as to support workpieces of different heights.
[0010] The box body is also equipped with a concave hot oil chamber surrounding the drying chamber. Two oil guide pipes connected to the hot oil chamber are fixed on the outside of the box body. The two oil guide pipes are respectively connected to the oil outlet and oil inlet of the thermal electric boiler. High temperature heat transfer oil is pumped along the hot oil chamber and the two oil guide pipes to form a closed circulation oil circuit so as to continuously heat the hot oil chamber and the drying chamber.
[0011] An exhaust pipe connected to the drying chamber is fixed on the upper surface of the box. Moisture on the workpiece is evaporated by the high temperature environment, forming water vapor which is sent into the air conditioning system along the exhaust pipe and discharged into the air, or sent into the waste heat recovery device to use its heat for preheating of the heat transfer oil.
[0012] An air inlet pipe connected to the drying chamber is fixed on the lower surface of the housing. The internal pressure in the drying chamber can be monitored in real time by a pressure gauge. When the internal pressure is low, the air inlet pipe can be opened and fresh air can be supplied by the air conditioning system to balance the internal pressure of the drying chamber.
[0013] The technical effects achieved by this utility model are as follows:
[0014] This utility model relates to a zero-gas-consumption drying device using a thermal power boiler. When drying workpieces, a square cloth and its four corner posts form a bowl-shaped tray. The workpiece with the sprayed coating is placed in the bowl-shaped tray along with a base, with the ventilation holes of the partitions staggered. These partitions are then stacked one by one in the drying chamber. The chamber door is closed, and the thermal power boiler is started to pump high-temperature heat transfer oil into the chamber, transferring heat to the drying chamber to raise its temperature to a specified range to heat the sprayed coating workpiece. If coating drips from the workpiece, the bowl-shaped tray can catch the dripping paint. Simultaneously, the workpiece is supported by the base and suspended on the bowl-shaped tray, facilitating separation between the workpiece and the dripping paint, preventing the coating from thickening, and improving the protective effect of the heat transfer oil on the coated workpiece within the drying chamber. After the coating hardens, drying is completed, the thermal power boiler is stopped, and finally, the chamber door is opened to remove the workpiece and partitions. Attached Figure Description

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figure 1-6 As shown, a zero-gas-consumption drying device using a thermal electric boiler includes a housing 1 and a thermal electric boiler 2 connected to the housing 1. The thermal electric boiler 2 can be a commercially available WY-YL21060303 model thermal oil electric boiler, which adopts PID microcomputer control, is made of carbon steel and 304 stainless steel, has a power of 30-800KW, and a working voltage of 380W. The housing 1 contains a drying chamber 3 and several partitions 4 arranged in a vertical array inside the drying chamber 3. The partitions 4 are all perforated square plate structures. Several square cloth blocks 5 are provided on the upper surface of each partition 4. The square cloth blocks 5 can be made of high-temperature aluminum foil fiberglass cloth, which can withstand 400-500℃ for a long time. The four corners of the square cloth blocks 5 are folded upwards and fixed with columns 6. The columns 6 can be made of high-temperature resistant alloy materials, such as high manganese alloy. The columns 6 and adjacent partitions 4 are detachably connected. 1. Equipped with a door that can be opened or closed, when drying workpieces, a bowl-shaped tray is formed using square cloth 5 and its four corner posts 6. The workpiece with the sprayed coating is placed in the bowl-shaped tray along with the base, staggered from the ventilation holes of the partition 4. Then, these partitions 4 are stacked one by one in the drying chamber 3. The door is closed, and the thermal boiler 2 is started to pump high-temperature heat transfer oil into the interior of the chamber 1, transferring heat to the drying chamber 3 so that the drying chamber 3 can be heated to the specified range to heat the workpiece with the sprayed coating. If the workpiece drips paint, the bowl-shaped tray can catch the dripping paint on the workpiece. At the same time, these workpieces are supported by the base and suspended on the bowl-shaped tray, which facilitates the separation of the workpiece from the dripping paint, prevents the coating workpiece from thickening, and improves the protective effect of the heat transfer oil drying chamber 3 on the coated workpiece. After the coating hardens, the drying ends, the thermal boiler 2 is controlled to stop heating, and finally the door is opened to take out these workpieces and partitions 4.
[0025] Among them, the bowl-shaped tray is easy to remove and replace. Even if it is covered with paint, it can be easily removed for cleaning without having to be scrapped, which can save costs.
[0026] like Figure 5 and Figure 6 As shown, several fastening screws 7 are threaded on the lower surface of the partition 4. The upper ends of the fastening screws 7 all face upward and penetrate the adjacent partition 4 and are threaded with the lower ends of the adjacent columns 6. Tightening the fastening screws 7 in the forward direction along the thread until they are unscrewed can separate the partition 4 and the corresponding column 6, making it easy to disassemble the bowl-shaped tray. Conversely, tightening the fastening screws 7 in the reverse direction along the thread until the column 6 on the partition 4 is tightened can easily fix the bowl-shaped tray.
[0027] like Figure 3 and Figure 4 As shown, two sets of load plates 8 are distributed on both sides of the drying chamber 3. Several load plates 8 are arranged in a vertical array inside the drying chamber 3. Storage spaces are formed above the two opposing load plates 8. In this way, several storage spaces are arranged vertically at equal intervals, which makes it convenient to put the partition 4 into different storage spaces and to easily adjust the distance between the two partitions 4, so as to support workpieces of different heights.
[0028] like Figure 1 and Figure 3 As shown, the box body 1 is also provided with a hot oil chamber 9 that is concave and surrounds the drying chamber 3. Two oil guide pipes 10 that are connected to the hot oil chamber 9 are fixed on the outside of the box body 1. The two oil guide pipes 10 are respectively connected to the oil outlet and oil inlet of the thermal electric boiler 2. High temperature heat transfer oil is pumped between the hot oil chamber 9 and the two oil guide pipes 10 to form a closed circulation oil circuit so as to continuously heat the hot oil chamber 9 and the drying chamber 3.
[0029] like Figure 2 and Figure 3 As shown, an exhaust pipe 11 connected to the drying chamber 3 is fixed on the upper surface of the box 1. The moisture on the workpiece is evaporated by the high temperature environment, forming water vapor which is sent into the air conditioning system along the exhaust pipe 11 and discharged into the air, or sent into the waste heat recovery device to use its heat for the preheating of the heat transfer oil.
[0030] like Figure 2 and Figure 3 As shown, an air inlet pipe 12 connected to the drying chamber 3 is fixed on the lower surface of the housing 1. The air inlet pipe 12 is connected to the air conditioning system. The internal pressure in the drying chamber 3 can be monitored in real time by a pressure gauge. When the internal pressure is low, the air inlet pipe 12 can be opened to supply fresh air through the air conditioning system in order to balance the internal pressure of the drying chamber 3.
[0031] The working principle of this utility is as follows: When drying the workpiece, the square cloth 5 and the four corner posts 6 form a bowl-shaped tray. The workpiece with the spray coating is placed in the bowl-shaped tray along with the base, staggered from the ventilation holes of the partition 4. Then, these partitions 4 are stacked one by one in the drying chamber 3, and the door is closed.
[0032] Then, the thermal boiler 2 is started to pump high-temperature heat transfer oil into the housing 1, transferring heat to the drying chamber 3 so that the drying chamber 3 can be heated to the specified range to heat the workpiece with the coating. Once the workpiece drips paint, the dripping paint can be caught by the bowl-shaped tray. At the same time, these workpieces are supported by the base and suspended on the bowl-shaped tray, which facilitates the separation of the workpiece from the dripping paint, prevents the coating workpiece from thickening, and improves the protective effect of the heat transfer oil drying chamber 3 on the coated workpiece.
[0033] After the coating has hardened, the drying process ends. The control boiler 2 is then stopped heating. Finally, the box door is opened to remove the workpieces and partition 4.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
