Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to an energy-saving drying equipment for a painting workshop. Background Technology

[0002] The coating workshop is an important part of product manufacturing. Its main function is to coat the product surface to achieve purposes such as corrosion protection, decoration, and marking. After the coating process is completed in the coating workshop, the product surface needs to be dried using drying equipment, mostly through hot air drying.

[0003] Existing drying equipment uses blown hot air to achieve drying. During production line operation, there may be periods when there are no workpieces or production is suspended. If the drying equipment stops operating, the furnace temperature will drop. After production resumes, the temperature cannot be reached immediately, and the equipment needs to be manually turned on in advance to raise the temperature again. This process takes a long time. If the drying equipment runs continuously, it will cause energy waste, leading to increased energy consumption and thus increased operating costs. Utility Model Content

[0004] The main objective of this invention is to provide an energy-saving drying device for painting workshops, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An energy-saving drying device for a painting workshop includes a conveyor frame, a drying box on the conveyor frame, a hot air blower on the top of the drying box, an air inlet pipe connected to the hot air blower, an air outlet hood at the top of the interior of the drying box, a fixed plate at the lower end of the conveyor frame, a three-way connector connected to the air inlet pipe inside the fixed plate, a heat reflector plate at the bottom of the fixed plate, a preheating structure connected to the three-way connector, and a support structure in contact with the preheating structure on the heat reflector plate.

[0007] Preferably, the inner side of the conveyor frame is provided with a conveyor roller, and the end position of the conveyor frame is equipped with a support leg.

[0008] Preferably, the hot air blower is equipped with a conveying pipe, which passes through the top of the drying box and is connected to the air outlet hood.

[0009] Preferably, a controller is installed on the outer wall of the drying oven, and the end of the preheating structure passes through the fixed plate.

[0010] Preferably, the preheating structure includes a preheating bend, a threaded joint, an end cap, and a filter screen. One end of the preheating bend is connected to a tee joint, and the other end passes through a fixed plate. The threaded joint is located at the end of the preheating bend. The end cap and the filter screen are fixedly connected, and the end cap is threadedly connected to the threaded joint.

[0011] Preferably, the support structure includes a support rod, a suction cup, and a bidirectional screw. The support rod is fixedly connected to the suction cup, and the suction cup is adsorbed onto the heat reflector plate. The bidirectional screw is threadedly connected to the support rod.

[0012] Preferably, the support structure further includes a support base, a spring, a connecting rod, and an adjusting knob. The support base and the spring are fixedly connected, and the support base is connected to the connecting rod. The connecting rod is threaded onto a bidirectional screw, and the adjusting knob is fixed onto the bidirectional screw.

[0013] Compared with existing technologies, this utility model has the following beneficial effects: The energy-saving drying device in this painting workshop, through its three-way connector, heat reflector, and preheating structure, preheats the gas inside the preheating structure after passing through the product during hot air drying. The preheated gas then enters the hot air blower through the air inlet pipe and is finally blown out, achieving preheating of the incoming air and reducing the energy consumption required for subsequent heating. The heat reflector reflects heat, further enhancing the drying effect on the product and achieving energy savings. Furthermore, when the device is restarted after a pause, the preheating structure, in conjunction with the heat reflector, shortens the time it takes for the temperature inside the drying chamber to rise, facilitating rapid attainment of the process temperature for continued drying. The use of a support structure and suction cups for installation prevents damage to the heat reflector. The connection between the support rod and connecting rod using a bidirectional screw allows for quick adjustment of the support position, improving operational flexibility.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, an energy-saving drying device for a painting workshop includes a conveyor frame 1, a drying box 2 on the conveyor frame 1, a hot air blower 3 on the top of the drying box 2, an air inlet pipe 4 connected to the hot air blower 3, an air outlet hood 5 at the top inside the drying box 2, a fixing plate 7 at the lower end of the conveyor frame 1, a three-way connector 6 connected to the air inlet pipe 4 inside the fixing plate 7, a heat reflector plate 8 at the bottom of the fixing plate 7, a preheating structure 9 connected to the three-way connector 6, and a support structure 10 in contact with the preheating structure 9 on the heat reflector plate 8.

[0021] The inner side of the conveyor frame 1 is equipped with a conveyor roller, and a support leg 12 is installed at the end of the conveyor frame 1. The hot air blower 3 is equipped with a conveyor pipe 11, which passes through the top of the drying chamber 2 and connects to the air outlet hood 5. A controller 13 is installed on the outer wall of the drying chamber 2, and the end of the preheating structure 9 passes through the fixed plate 7.

[0022] When using the drying device, the device is placed on the support leg 12 at the end of the conveyor frame 1. After the device is started, the conveyor roller rotates, and the hot air fan 3 runs and draws air through the air inlet pipe 4. Outside air enters the air inlet pipe 4 through the preheating structure 9 and finally enters the hot air fan 3 for heating. After the gas is heated, it is conveyed from the conveyor pipe 11 to the air outlet hood 5 and finally blown out through the air outlet hood 5 to act on the drying chamber 2. The coated product is placed on the conveyor roller, and the conveyor roller conveys the product. The product enters the drying chamber 2 for drying. During the drying process, the heat reflector plate 8 on the inner side of the fixed plate 7 can reflect heat, which can increase the drying effect of the product. At the same time, the heat also acts on the preheating structure 9 to preheat the gas entering the preheating structure 9, which can reduce the energy consumption required for subsequent heating of the gas and achieve the effect of energy saving.

[0023] If there are no products on the production line, the hot air blower 3 can be stopped and the drying device can be stopped. When it is necessary to dry the products again, the device can be started by the controller 13 and the air can be blown according to the above process. The blown hot air acts on the preheating structure 9 for preheating, which can shorten the time for the temperature inside the drying box 2 to rise. The process temperature can be reached in a shorter time, which can also save energy.

[0024] According to the above implementation scheme, the preheating structure 9 includes a preheating bend 901, a threaded joint 902, an end cap 903, and a filter screen 904. One end of the preheating bend 901 is connected to the tee joint 6, and the other end passes through the fixing plate 7. The threaded joint 902 is located at the end of the preheating bend 901. The end cap 903 and the filter screen 904 are fixedly connected, and the end cap 903 is threadedly connected to the threaded joint 902.

[0025] When installing the preheating structure 9, one end of the preheating bend 901 is connected to the tee connector 6, and the other end passes through the fixing plate 7. The end cap 903 with the filter screen 904 is installed onto the threaded connector 902, completing the installation of the preheating structure 9. A support structure 10 is set on the heat reflector plate 8 to support the preheating bend 901 and ensure its stability during use. During use, external air enters the preheating bend 901 after primary filtration by the filter screen 904, then enters the air inlet pipe 4 through the tee connector 6, and is finally heated and blown out by the hot air blower 3. The blown hot air not only dries the product but also preheats the gas flowing inside the preheating bend 901, reducing energy consumption.

[0026] According to the above implementation scheme, the support structure 10 includes a support rod 1001, a suction cup 1002, and a bidirectional screw 1006. The support rod 1001 is fixedly connected to the suction cup 1002, and the suction cup 1002 is attached to the heat reflector plate 8. The bidirectional screw 1006 is threadedly connected to the support rod 1001. The support structure 10 also includes a support base 1003, a spring piece 1004, a connecting rod 1005, and an adjusting knob 1007. The support base 1003 and the spring piece 1004 are fixedly connected, and the support base 1003 is connected to the connecting rod 1005. The connecting rod 1005 is threadedly connected to the bidirectional screw 1006, and the adjusting knob 1007 is fixed to the bidirectional screw 1006.

[0027] When installing the support structure 10, the suction cup 1002 at the lower end of the support rod 1001 is attached to the heat reflector plate 8 to ensure that the support base 1003 is located below the preheating bend 901. The support base 1003 is kept relatively fixed. The bidirectional screw 1006 is rotated by the adjusting knob 1007. The rotation of the bidirectional screw 1006 generates a force on the connecting rod 1005 and the support rod 1001, causing the connecting rod 1005 to rise relatively. The support base 1003 then carries the spring piece 1004 up until the spring piece 1004 contacts the preheating bend 901 and deforms. Under the action of the support base 1003 and the spring piece 1004, the preheating bend 901 is effectively supported, ensuring stability during use.

[0028] It should be noted that, through the three-way connector 6, heat reflector 8, and preheating structure 9, during hot air drying, the hot air blown out preheats the gas inside the preheating structure 9 after passing through the product. The preheated gas then enters the hot air blower 3 through the air inlet pipe 4 and is finally blown out, thus achieving preheating of the incoming air and reducing the energy consumption required for subsequent heating. The heat reflector 8 can reflect heat, further enhancing the drying effect on the product and achieving energy saving. At the same time, when the device is paused and restarted, the preheating structure 9, together with the heat reflector 8, can shorten the time for the temperature inside the drying chamber 2 to rise, making it easier to quickly reach the process temperature and continue the drying operation. The support structure 10 is used, and the entire structure is installed using suction cups 1002, which will not damage the heat reflector 8. The support rod 1001 and the connecting rod 1005 are connected using a bidirectional screw 1006, which can quickly adjust the position of the support base 1003 and improve the flexibility of use.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
