Description

Technical Field

[0001] This utility model relates to the technical field of surface drying chamber exhaust devices, specifically an energy-saving and consumption-reducing automatic exhaust device for surface drying chambers. Background Technology

[0002] A surface drying chamber, also known as a coating drying chamber, is a dedicated space for implementing the "surface drying" process. By controlling conditions such as temperature, humidity, or ventilation, the surface layer of materials such as coatings and adhesives is allowed to complete preliminary curing within a set time, forming a solid film layer that does not adhere to particles. During the use of the surface drying chamber, an automatic exhaust device is usually installed to regulate the internal air pressure and improve air quality.

[0003] In real life, when using an automatic exhaust device to exhaust the surface drying chamber, the emitted flue gas is usually recycled through heat exchange. However, because the high temperature environment reduces the fluid's solubility, some dissolved oxygen, hydrogen and other gases are released as free bubbles and accumulate in the pipes. This can easily cause air blockage, thereby reducing heat exchange efficiency and increasing energy loss. Therefore, an energy-saving and consumption-reducing automatic exhaust device for the surface drying chamber is needed. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving and consumption-reducing automatic exhaust device for surface drying chambers, thereby solving the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an energy-saving and consumption-reducing automatic exhaust device for surface drying chambers, comprising:

[0006] A first exhaust pipe is provided, one end of which is fixedly equipped with a heat exchange box, a second exhaust pipe is fixedly provided on one side of the heat exchange box, a heat exchange tube is fixedly provided inside the heat exchange box, and a connecting seat is fixedly provided at the top end of the second exhaust pipe.

[0007] An exhaust component includes a motor. The output end of the motor is fixedly provided with a rotating shaft. The bottom end of the rotating shaft is fixedly provided with an exhaust fan blade. The outer wall of the rotating shaft is fixedly provided with a first pulley. The outer wall of the first pulley is fitted with a transmission belt, and a second pulley is connected to it via the transmission belt. The inner wall of the second pulley is fixedly provided with a connecting shaft, and the bottom end of the connecting shaft is fixedly provided with an auxiliary fan blade.

[0008] Furthermore, the two sides of the outer wall of the rotating shaft respectively penetrate the top of the connecting seat and the top of the second exhaust pipe.

[0009] Furthermore, the top end of the connecting shaft is connected to the inner top end bearing of the connecting seat, and the outer wall of the connecting shaft penetrates the top end of the first exhaust pipe.

[0010] Furthermore, a water inlet pipe is connected to one side of the top of the heat exchange box, a drain pipe is connected to one side of the bottom of the heat exchange box, and four support columns are fixedly installed on the other side of the heat exchange box.

[0011] Furthermore, reinforcing seats are fixedly provided on both sides of the second exhaust pipe, and one side of each of the two reinforcing seats is fixedly connected to one side of the heat exchange box.

[0012] Furthermore, one end of the heat exchange tube is connected to the inside of the first exhaust pipe, and the other end of the heat exchange tube is connected to the inside of the second exhaust pipe.

[0013] Furthermore, the heat exchange tube is S-shaped overall.

[0014] This utility model has the following beneficial effects:

[0015] This invention, by incorporating an exhaust fan blade and an auxiliary fan blade, utilizes a motor that drives the exhaust fan blade to rotate via a rotating shaft. Simultaneously, the rotating shaft, through two pulleys, drives a connecting shaft to rotate, which in turn drives the auxiliary fan blade to rotate. This achieves automatic exhaust from both the first and second exhaust pipes. By using a motor to drive both the exhaust fan blade and the auxiliary fan blade, the overall exhaust efficiency of the exhaust system is improved. This prevents dissolved oxygen, hydrogen, and other gases from precipitating as free bubbles and accumulating in the pipes, thus avoiding air resistance and improving heat exchange efficiency while reducing energy loss. Furthermore, by using a single motor to drive two fan blades, exhaust costs are reduced, thereby lowering energy consumption. Attached Figure Description

[0027] The first exhaust pipe 11 is connected to the wall of the surface drying chamber. The heat exchange box 12 is used to hold the heat exchange water. The heat exchange tube 13 is used to exchange the high-temperature exhaust gas inside with the water in the heat exchange box 12. The second exhaust pipe 14 is used to discharge the gas after heat exchange to the outside. The connecting seat 21 is L-shaped.

[0028] The exhaust component includes a motor 31. The output end of the motor 31 is fixedly provided with a rotating shaft 32. The bottom end of the rotating shaft 32 is fixedly provided with an exhaust fan blade 33. The outer wall of the rotating shaft 32 is fixedly provided with a first pulley 34. The outer wall of the first pulley 34 is fitted with a transmission belt 35, and a second pulley 36 is connected to it through the transmission belt 35. The inner wall of the second pulley 36 is fixedly provided with a connecting shaft 37. The bottom end of the connecting shaft 37 is fixedly provided with an auxiliary fan blade 38.

[0029] The motor 31 is used to provide the driving force required for the exhaust fan blades 33 and auxiliary fan blades 38 to rotate and exhaust. The motor 31 is fixed to the top of the connecting seat 21. The exhaust fan blades 33 and auxiliary fan blades 38 are respectively installed in the second exhaust pipe 14 and the first exhaust pipe 11, and do not contact the inner walls of the two. A control panel is installed on one side of the heat exchange box 12, and the motor 31 is electrically connected to the external power supply through the control panel.

[0030] The top ends of the connecting seat 21 and the top ends of the second exhaust pipe 14 are respectively penetrated on both sides of the outer wall of the rotating shaft 32.

[0031] The rotating shaft 32 is rotatably engaged with the connecting seat 21 and the second exhaust pipe 14.

[0032] The top end of the connecting shaft 37 is connected to the inner top end bearing of the connecting seat 21, and the outer wall of the connecting shaft 37 penetrates the top end of the first exhaust pipe 11;

[0033] The connecting shaft 37 is connected to the connecting seat 21 for rotation, and the connecting shaft 32 is rotatably engaged with the first exhaust pipe 11.

[0034] A water inlet pipe 121 is connected to one side of the top of the heat exchange box 12, a drain pipe 122 is connected to one side of the bottom of the heat exchange box 12, and four support columns 23 are fixedly provided on the other side of the heat exchange box 12.

[0035] The inlet pipe 121 is used to deliver water to be exchanged in the heat exchange box 12, and the drain pipe 122 is used to discharge the water after heat exchange in the heat exchange box 12 to the outside. One end of the support column 23 is fixedly connected to the wall of the surface drying chamber, and is further supported by the overall exhaust device of the support column 23, thereby improving the overall stability.

[0036] The second exhaust pipe 14 is fixedly provided with reinforcing seats 22 on both sides, and one side of the two reinforcing seats 22 is fixedly connected to one side of the heat exchange box 12 respectively.

[0037] The reinforcing seat 22 is used to increase the stability of the connection between the second exhaust pipe 14 and the heat exchange box 12.

[0038] Working principle: When motor 31 is turned on, it drives shaft 32 to rotate, which in turn drives exhaust fan blade 33 to rotate. Simultaneously, shaft 32 drives first pulley 34 to rotate, which in turn drives second pulley 36 via transmission belt 35. Second pulley 36, in turn, drives auxiliary fan blade 38 via connecting shaft 37. Under the action of exhaust fan blade 33 and auxiliary fan blade 38, the high-temperature gas in the surface drying chamber is discharged outwards. The high-temperature gas enters heat exchange tube 13 through first exhaust pipe 11 and then... The heat exchange tube 13 exchanges heat with the water in the heat exchange box 12. The gas after heat exchange is discharged to the outside through the second exhaust pipe 14. The exhaust fan blades 33 and auxiliary fan blades 38 driven by the motor 31 can increase the overall exhaust effect of the exhaust device and prevent some dissolved oxygen, hydrogen and other gases from precipitating into free bubbles and accumulating in the pipe. This avoids air resistance and improves heat exchange efficiency, reduces energy loss. At the same time, the exhaust cost can be reduced by using one motor to drive two fan blades, thereby reducing energy consumption.

[0040] One end of the heat exchange tube 13 is connected to the inside of the first exhaust pipe 11, and the other end of the heat exchange tube 13 is connected to the inside of the second exhaust pipe 14.

[0041] The heat exchange tube 13 is made of copper, which can increase the overall thermal conductivity of the heat exchange tube 13.

[0042] The heat exchange tube 13 is S-shaped.

[0043] Working principle: When the high-temperature gas is discharged into the heat exchange tube 13 and exchanges heat with the heat exchange box 12, the overall heat exchange efficiency of the high-temperature gas can be improved through the copper heat exchange tube 13. At the same time, the heat exchange tube 13 adopts an S-shaped tube, which can increase the transport time of the high-temperature gas in the heat exchange tube 13, thereby further increasing the heat exchange efficiency of the high-temperature gas.
