[0039] Embodiment 1

[0040] During the production process of the enameling machine, smoke and paint powder will be brought out at the outlet of the drying furnace along with the transportation of the enameled wire, causing pollution to the production environment and affecting the health of the production personnel. Therefore, as the country's requirements for production environmental protection continue to increase, and in order to ensure the production safety of production personnel, it is necessary to recycle and treat the smoke, paint powder and other waste gases of the enameling machine. The existing technology is unable to fully cover the upper port of the barreled material, resulting in the harmful gas easily overflowing into the environment during the process of sucking out, causing environmental pollution. Therefore, this application needs to solve the problem of how to fully cover the outlet of the drying furnace to recover smoke, paint powder and other waste gases, so as to avoid causing pollution to the production environment.

[0041] In response to the above problems, an embodiment of the present application provides a waste gas recovery device at the outlet of an enameling machine furnace, which can recycle and treat waste gases such as smoke and paint powder at the outlet of the enameling machine furnace, avoid causing pollution to the production environment, and ensure the production safety of production personnel.

[0042] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1 and Figure 2 The embodiment of the present application shows an embodiment of the exhaust gas recovery device at the outlet of the enameling machine oven, which includes:

[0044] An exhaust gas collecting cover 1 and a dust collecting base 2, wherein an exhaust gas transmission pipe 3 is provided on the exhaust gas collecting cover 1, and the exhaust gas transmission pipe 3 is connected to the exhaust gas treatment device 4 of the enameling machine, and a negative pressure exhaust fan 5 is provided at the exhaust port 41 of the exhaust gas treatment device 4. In the embodiment of the present application, the exhaust gas treatment device 4 and the negative pressure exhaust fan 5 can utilize the original exhaust gas treatment device and negative pressure fan of the enameling machine, or a new exhaust gas treatment device and negative pressure fan can be provided, which needs to be determined according to the actual application situation, and is not the only limitation here. It can be understood that the negative pressure exhaust fan 5 will generate negative pressure when working, and the negative pressure is a gas pressure state lower than the normal pressure, so that the exhaust gas generated by the enameling machine is sucked from the exhaust gas collecting cover 1, and transmitted to the exhaust gas treatment device 4 through the exhaust gas transmission pipe 3 for treatment.

[0045] like Figure 2 As shown, the dust collecting base 2 is provided with a first notch 21 and a second notch 22 on both sides in the width direction. When the exhaust gas collecting cover 1 and the dust collecting base 2 are assembled, the exhaust gas collecting cover 1 and the first notch 21 form a first opening, and the exhaust gas collecting cover 1 and the second notch 22 form a second opening. Figure 1As shown, taking the second notch 22 as an example, when the exhaust gas collection cover 1 and the dust collection base 2 are assembled, the wide side of the exhaust gas collection cover 1 and the wide side of the dust collection base 2 are fitted one by one, and the long side of the exhaust gas collection cover 1 forms an opening with the second notch 22, namely, the second opening. It is understandable that the other long side of the exhaust gas collection cover 1 and the first notch 21 also form an opening, namely, the first opening.

[0046] The first opening matches the size of the oven outlet of the enameling machine, so that the oven outlet can be covered within the first opening. It is understandable that in actual applications, the size of the oven outlet is diverse, and the size of the first opening can be adjusted according to the size of different oven outlets to ensure that the oven outlet can be covered within the first opening, ensuring air tightness, and the exhaust gas generated by the enameling machine cannot overflow. The second opening is the output port of the enameled wire produced by the enameling machine, and the enameled wire produced from the oven outlet is output from the second opening, ensuring that the enameled wire is first passed through the exhaust gas collection cover 1 to absorb the exhaust gas before being output.

[0047] The following beneficial effects can be seen from the above embodiment 1:

[0048] The exhaust gas recovery device at the outlet of the enameling machine baking furnace of the present application is provided with an exhaust gas collecting cover and a dust collecting bottom support, the exhaust gas collecting cover is provided with an exhaust gas transmission pipe, the exhaust gas transmission pipe is connected with the exhaust gas treatment device of the enameling machine, and a negative pressure exhaust fan is provided at the exhaust port of the exhaust gas treatment device. The original negative pressure exhaust fan of the enameling machine is used to form a negative pressure on the exhaust gas, so that the exhaust gas can be sucked into the exhaust gas treatment device, and the exhaust gas is treated by the original exhaust gas treatment device of the enameling machine, thereby reducing production costs and improving production efficiency; a first notch and a second notch are respectively provided on both sides of the width direction of the dust collecting bottom support. When the exhaust gas When the exhaust gas collection cover and the dust collection base are assembled, the exhaust gas collection cover and the first notch form a first opening, and the exhaust gas collection cover and the second notch form a second opening, wherein the first opening matches the size of the drying furnace outlet of the enameling machine, and the second opening is the output port of the enameled wire produced by the enameling machine, so that the drying furnace outlet can be covered within the first opening, so that the drying furnace outlet can be fully covered to prevent the overflow of exhaust gas, avoid pollution of the production environment, and ensure the production safety of production personnel. At the same time, it has no impact on the production and transportation of the enameled wire, thereby ensuring the production efficiency of the enameled wire.

[0049] Embodiment 2

[0050] For ease of understanding, an embodiment of the exhaust gas recovery device at the outlet of the enameling machine oven is provided below for illustration. In actual applications, in order to avoid the uneven distribution of the negative pressure suction force generated by the negative pressure exhaust fan, the exhaust gas can be fully absorbed and the exhaust gas can be collected and transported after being absorbed, and the exhaust gas collection cover will be further designed.

[0051] See also Figure 3 and Figure 4 The second embodiment of the waste gas recovery device at the outlet of the enameling machine oven shown in the embodiment of the present application includes:

[0052] The exhaust gas collecting cover 1 includes a docking cover 11 and an exhaust gas collecting hood 12, wherein the exhaust gas collecting hood 12 is a trapezoidal structure, and a plurality of exhaust gas absorption holes 13 are provided on the lower bottom surface of the exhaust gas collecting hood 12 and the connecting surface of the docking cover 11. The length of the lower bottom surface is equal to the length of the docking cover 11, and the width of the lower bottom surface is less than or equal to the width of the docking cover 11, so that the connecting surface can cover a sufficiently large area of ​​the docking cover 11, and the plurality of exhaust gas absorption holes 13 can be densely distributed on the connecting surface, so that the negative pressure suction force generated by the negative pressure exhaust fan 5 is evenly distributed on the connecting surface, avoiding the negative pressure suction force being concentrated only on the connection between the exhaust gas transmission pipeline 3 and the exhaust gas collecting cover 1, resulting in the exhaust gas not being fully absorbed. The exhaust gas collecting hood 12 is a trapezoidal structure. When the exhaust gas passes through a number of exhaust gas absorption holes 13 and enters the exhaust gas collecting hood 12, it can be understood that since the four side surfaces of the exhaust gas collecting hood 12 are inclined surfaces and are gathered from the lower bottom surface to the upper bottom surface, the exhaust gas inside the exhaust gas collecting hood 12 can be gathered to the upper bottom surface along the four side surfaces of the exhaust gas collecting hood 12, and the exhaust gas transmission pipe 3 is connected to the upper bottom surface of the exhaust gas collecting hood 12, so the exhaust gas transmission pipe 3 can fully absorb the exhaust gas.

[0053] The following beneficial effects can be seen from the above-mentioned embodiment 2:

[0054] By setting the exhaust gas collecting hood as a trapezoidal structure, the exhaust gas inside the exhaust gas collecting hood can be concentrated and absorbed by the exhaust gas transmission pipe; a number of exhaust gas absorption holes are set on the connecting mating surface between the lower bottom surface of the exhaust gas collecting hood and the docking cover, so that the negative pressure suction force generated by the negative pressure exhaust fan is evenly distributed on the connecting mating surface, and the exhaust gas is fully absorbed, avoiding the negative pressure suction force being concentrated only at the connection between the exhaust gas transmission pipe and the exhaust gas collecting cover, resulting in the exhaust gas cannot be fully absorbed, avoiding pollution of the production environment, and ensuring the production safety of production personnel.

[0055] Embodiment 3

[0056] For ease of understanding, an embodiment of the exhaust gas recovery device at the outlet of the enameling machine furnace is provided below for illustration. In actual applications, in order to further prevent the exhaust gas from overflowing, the opening width of the second opening will be further reduced, and the exhaust gas collecting cover and the dust collecting base will be locked together by buckles. The material of the exhaust gas collecting cover, the dust collecting base and the exhaust gas transmission pipeline will also be set to anti-corrosion material to prevent the exhaust gas from corroding and causing exhaust gas leakage, thereby polluting the production environment.

[0057] See also Figure 1 The third embodiment of the waste gas recovery device at the outlet of the enameling machine oven shown in the embodiment of the present application includes:

[0058] The opening width of the second opening is greater than the wire diameter of the enameled wire and smaller than the opening width of the first opening. The opening width refers to the distance between the exhaust gas collection cover 1 and the bottom line of the first notch 21 or the second notch 22. In the embodiment of the present application, the opening width of the second opening is as small as possible, but the width for the enameled wire to pass through needs to be retained to ensure that the enameled wire can be output from the enameling machine. It can be understood that the shape of the second notch 22 forming the second opening with the exhaust gas collection cover 1 can be rectangular or other shapes. For example, if the output trajectory of the enameled wire is fixed, the second notch 22 can be set only at the position where the output trajectory of the enameled wire intersects with the dust collection base 2. At this time, the second notch 22 can be multiple, and its shape can be arc-shaped or rectangular. The size of the second opening formed with the exhaust gas collection cover 1 only needs to be sufficient for the enameled wire to pass through, and the sealing is better.

[0059] It is understandable that, in actual applications, the shape and arrangement of the second notch 22 forming the second opening with the exhaust gas collecting cover 1 are various and need to be determined according to the actual application situation, and are not limited here.

[0060] A buckle 6 is provided at the assembly connection position between the docking cover 11 and the dust collection base 2, and the buckle 6 includes a fixed hook buckle 61, a fixed bracket 62 and a locking handle 63. The fixed hook buckle 61 is installed on the side walls on both sides of the length direction of the docking cover 11, and the fixed bracket 62 is installed on the side walls on both sides of the length direction of the dust collection base 2. When the docking cover 11 and the dust collection base 2 are assembled, one end of the locking handle 63 is locked on the fixed hook buckle 61, and the other end is fixed on the fixed bracket 62, which effectively improves the stability between the exhaust gas collection cover 1 and the dust collection base 2 and enhances the sealing. It is understandable that the exhaust gas may contain paint powder and other substances in solid form. If these substances cannot be absorbed, they will fall into the dust collection base 2 for collection. The buckle 6 can also flexibly separate the exhaust gas collection cover 1 and the dust collection base 2 when the enameling machine is shut down, so as to clean the dust and other solid substances collected inside the dust collection base 2.

[0061] Since the exhaust gas generated by the enameling machine is corrosive, in order to prevent the exhaust gas from causing corrosion damage to the exhaust gas collecting cover 1, the dust collection base 2 and the exhaust gas transmission pipe 3, resulting in the exhaust gas overflowing from the damaged position and polluting the production environment, the exhaust gas collecting cover 1, the dust collection base 2 and the exhaust gas transmission pipe 3 are all made of anti-corrosion materials. Exemplarily, the anti-corrosion material can be 304 stainless steel. It can be understood that in actual applications, there are various anti-corrosion materials, and the appropriate anti-corrosion material needs to be determined according to the actual application situation. This is not the only limitation here.

[0062] The following beneficial effects can be seen from the above embodiment 3:

[0063] By further reducing the opening width of the second opening, the exhaust gas collection cover and the dust collection base are locked together by a buckle, and the materials of the exhaust gas collection cover, the dust collection base and the exhaust gas transmission pipeline are set to be anti-corrosion materials, the air tightness of the exhaust gas recovery device at the outlet of the enameling machine furnace of the present application is enhanced, exhaust gas overflow is avoided, the production environment is optimized, and the production safety of production personnel is ensured.

[0064] Embodiment 4

[0065] For ease of understanding, an embodiment of a waste gas recovery device at the outlet of an enameling machine oven is provided below for illustration. In actual applications, the absorbed waste gas will be subjected to combustion catalytic treatment through a waste gas treatment device to fully degrade the waste gas and avoid environmental pollution.

[0066] See also Figure 1 The fourth embodiment of the waste gas recovery device at the outlet of the enameling machine oven shown in the embodiment of the present application includes:

[0067] In the embodiment of the present application, the original waste gas treatment device 4 of the enameling machine can be used to treat the waste gas, and a flange opening 421 can be set at the air inlet 42 of the waste gas treatment device 4, and the waste gas transmission pipeline 3 is connected to the flange opening 421, so that the waste gas is passed into the waste gas treatment device 4. A suction regulating valve 31 is provided on the waste gas transmission pipeline 3, and the suction can be adjusted by the suction regulating valve 31. The suction can be set according to the output speed of the enameled wire. Assuming that the output speed of the enameled wire is faster, the enameled wire stays in the waste gas recovery device at the outlet of the enameling machine furnace for a short time, so it is necessary to increase the suction to absorb the waste gas brought out by the enameled wire at a faster rate. It can be understood that there are various ways to adjust the suction. In actual applications, the adjustment method needs to be determined according to the actual application situation, and it is not limited here.

[0068] The exhaust gas treatment device has a catalytic inner tank 43 and an auxiliary electric heating tube 44. The catalytic inner tank 43 has a ceramic catalyst block, which can treat volatile organic compounds such as benzene, ethers, phenols, etc. contained in the exhaust gas. When the ceramic catalyst block reaches the catalytic temperature, the ceramic catalyst block performs combustion catalytic treatment on the exhaust gas; when the ceramic catalyst block does not reach the catalytic temperature, the auxiliary electric heating tube 44 is started to heat the ceramic catalyst block, so that the ceramic catalyst block reaches the catalytic temperature and performs combustion catalytic treatment on the exhaust gas, thereby achieving the effect of degrading the exhaust gas.

[0069] From the above-mentioned fourth embodiment, the following beneficial effects can be seen:

[0070] The original waste gas treatment device of the enameling machine is used to treat the waste gas, which can reduce production costs, improve production efficiency, achieve the effect of degrading waste gas, meet environmental protection requirements, optimize the production environment, and ensure the production safety of production personnel.
