Description

Technical Field

[0001] This application relates to the field of glass processing equipment technology, and in particular to glass production equipment. Background Technology

[0002] During the production of glass, including screen printing and coating processes, the heating furnace of glass production equipment is prone to accumulating white powder and toxic gases. Typically, an exhaust system is installed at the top of the heating furnace, utilizing the pressure difference created by the temperature difference between the inside and outside of the furnace to expel the white powder and toxic gases generated inside.

[0003] However, when the exhaust system is continuously running, a temperature drop will occur inside the heating furnace. This drop is further exacerbated by the continuous introduction of low-temperature compressed air from the convection system. Excessive cooling inside the furnace can affect the flatness of the glass, causing waviness, edge curling, and other defects. This necessitates continuous heating of the furnace to maintain the required production temperature, leading to excessively high production costs. Utility Model Content

[0004] Therefore, it is necessary to provide a glass production equipment to address the problem of large temperature drops inside the heating furnace caused by the exhaust device.

[0005] This application provides a glass production equipment, the glass production equipment comprising:

[0006] A heating furnace body, wherein the heating furnace body is provided with a furnace body exhaust port;

[0007] A hot gas filtration and recovery device includes a filtration chamber and a filtration assembly; the filtration chamber is provided with a filtration inlet and a filtration outlet, the filtration inlet being connected to the furnace body exhaust outlet; the filtration assembly is disposed in the filtration chamber and is used to filter the hot gas entering from the filtration inlet, and the filtration outlet is used to discharge the filtered hot gas.

[0008] A compressed gas supply device includes a delivery pipeline connected to the interior of the heating furnace body for delivering compressed gas into the heating furnace body;

[0009] At least a portion of the conveying pipe is disposed within the filter chamber.

[0010] In one embodiment, the delivery pipe disposed within the filter chamber is defined as a preheating pipe; the preheating pipe is bent within the filter chamber.

[0011] In one embodiment, the filtering component includes:

[0012] Multiple filters are spaced apart between the air inlet and the exhaust outlet; the preheating pipe passes around the multiple filters.

[0013] In one embodiment, the plurality of filters divide the filter chamber into a plurality of sequentially arranged filter areas, with the two outermost filter areas respectively connected to the filter inlet and the filter outlet.

[0014] In one embodiment, the filter inlet and the filter outlet are disposed on the inner wall surface of the filter chamber adjacent to the filter screen.

[0015] In one embodiment, the preheating pipe passes through each of the filter areas and abuts against the inner wall of the filter chamber within the filter area.

[0016] In one embodiment, the filtering component further includes:

[0017] A fastener for securing the preheating pipe and / or the filter screen to the inner wall surface of the filter chamber.

[0018] In one embodiment, the preheating pipe has a preheating inlet and a preheating outlet, which are respectively disposed on two opposite side walls of the filter chamber.

[0019] In one embodiment, the hot gas filtration and recovery device further includes:

[0020] An insulation layer is provided on the outer surface of the filter chamber.

[0021] In one embodiment, the hot gas filtration and recovery device further includes:

[0022] A negative pressure device is provided at the filter exhaust port; the negative pressure device is used to create negative pressure at the filter exhaust port.

[0023] The aforementioned glass production equipment incorporates a hot gas filtration and recovery device to filter hot gases containing powder or toxic gases generated within the heating furnace. This device comprises a filtration chamber and filtration components, with a filtration inlet and an exhaust outlet on the filtration chamber. The filtration inlet connects to the heating furnace body, allowing hot gases from the furnace to be discharged into the filtration chamber for filtration before exiting through the exhaust outlet. A compressed gas supply device supplies compressed gas to the heating furnace to meet the process requirements of glass production. By partially locating the compressed gas delivery pipeline within the filtration chamber, the hot gas temperature within the filtration chamber heats the pipeline, increasing the temperature of the compressed gas delivered to the furnace. This mitigates the temperature drop caused by injecting compressed gas into the furnace and reduces the heating costs required to maintain the production temperature within the furnace.

[0039] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the glass production equipment provided in one embodiment of the present application from one perspective. Figure 2 This shows a schematic diagram of the structure of the hot gas filtration and recovery device 2 provided in one embodiment of the present application from one perspective; Figure 3 A cross-sectional view of the hot gas filtration and recovery device 2 provided in one embodiment of this application is shown.

[0040] This application provides a glass production equipment, which includes a heating furnace body 1, a hot gas filtration and recovery device 2, and a compressed gas supply device. The heating furnace body 1 is provided with a furnace exhaust port. The hot gas filtration and recovery device 2 includes a filtration chamber 21 and a filtration assembly 22. The filtration chamber 21 is provided with a filtration inlet 211 and a filtration exhaust port 212. The filtration inlet 211 is connected to the furnace exhaust port. The filtration assembly 22 is disposed in the filtration chamber 21 and is used to filter the hot gas entering from the filtration inlet 211. The filtration exhaust port 212 is used to discharge the filtered hot gas. The compressed gas supply device includes a conveying pipe that communicates with the interior of the heating furnace body 1 and is used to convey compressed gas into the heating furnace body 1. At least a portion of the conveying pipe is disposed within the filtration chamber 21.

[0041] The glass production equipment provided in this application embodiment filters the hot gas containing powder or toxic gas generated in the heating furnace 1 by setting a hot gas filtration and recovery device 2. The hot gas filtration and recovery device 2 is configured to include a filtration chamber 21 and a filtration assembly 22. A filtration inlet 211 and a filtration outlet 212 are provided on the filtration chamber 21. The filtration inlet 211 is connected to the heating furnace 1 so that the hot gas in the heating furnace 1 is discharged into the filtration chamber 21 for filtration and then discharged through the filtration outlet 212. A compressed gas supply device is provided to supply compressed gas into the heating furnace 1 to meet the process requirements of glass preparation. By at least partially locating the compressed gas supply pipeline within the filtration chamber 21, the hot gas temperature within the filtration chamber 21 is used to heat the supply pipeline, thereby increasing the temperature of the compressed gas supplied to the heating furnace 1. This alleviates the temperature drop problem caused by injecting compressed gas into the heating furnace 1 and helps reduce the heating cost required to maintain the production temperature within the heating furnace 1.

[0042] Specifically, the filter chamber 21 is located at the top of the heating furnace body 1 along the Z direction. The filter inlet 211 and the filter outlet 212 are respectively located on two opposite side walls of the filter chamber 21 along the Y direction. The filter outlet 212 is positioned higher than the filter inlet 211, allowing hot air to rise naturally after entering the filter chamber 21 through the filter inlet 211 and then exit through the filter outlet 212.

[0043] Combination Figure 1 and Figure 4 As shown, Figure 4 The diagram shows a schematic structural view of the glass production equipment provided in one embodiment of this application from another perspective. In some embodiments, the glass production equipment further includes an exhaust pipe 10, one end of which is connected to the furnace exhaust port of the heating furnace body 1, and the other end is connected to the filter inlet 211, so as to realize the communication between the heating furnace body 1 and the filter chamber 21 through the exhaust pipe 10, so that the hot air generated in the heating furnace body 1 enters the filter chamber 21 for filtration through the exhaust pipe 10.

[0044] In some embodiments, please refer to Figure 3 The conveying pipe set inside the filter chamber 21 is defined as the preheating pipe 3; the preheating pipe 3 is bent and set inside the filter chamber 21. By bending the preheating pipe 3 inside the filter chamber 21, the preheating pipe 3 and the hot gas inside the filter chamber 21 can have a larger contact area, thereby improving the heating effect on the compressed gas inside the preheating pipe 3.

[0045] Specifically, the preheating pipe 3 has a preheating air inlet 31 and a preheating air outlet 32, which are respectively located on two opposite side walls of the filter chamber 21. Optionally, the preheating air inlet 31 and the preheating air outlet 32 ​​are respectively located on two opposite side walls of the filter chamber 21 along the X direction, and the preheating pipe 3 is arranged in an S-shape between the two opposite side walls of the filter chamber 21 along the X direction, so that the preheating pipe 3 has a large length in the filter chamber 21 to maintain a large contact area with the hot air in the filter chamber 21.

[0046] Combination Figure 5 As shown, Figure 5 The diagram shows a schematic view of the hot gas filtration and recovery device 2 provided in one embodiment of this application from another perspective. Optionally, the filtration chamber 21 is configured as a cuboid structure, with the filtration inlet 211, filtration exhaust outlet 212, preheating inlet 31, and preheating outlet 32 ​​respectively disposed on the four side walls of the filtration chamber 21.

[0047] In some embodiments, please refer back to the documentation. Figure 3 The filter assembly 22 includes multiple filter screens 221, which are spaced apart between the filter inlet 211 and the filter outlet 212. This allows hot air entering the filter chamber 21 through the filter inlet 211 to be filtered by the multiple filter screens 221 and then discharged through the filter outlet 212. The preheating pipe 3 is routed around the multiple filter screens 221 to achieve a bent configuration of the preheating pipe 3 and to avoid interference between the preheating pipe 3 and the filter screens 221.

[0048] Specifically, multiple filters 221 divide the interior of the filter chamber 21 into multiple sequentially arranged filter areas 210. The two outermost filter areas 210 are connected to the filter inlet 211 and the filter outlet 212, respectively, so that the hot air entering through the filter inlet 211 flows through each filter area 210 in sequence and is discharged from the filter outlet 212.

[0049] In this embodiment, the filter inlet 211 and filter outlet 212 are disposed on the inner wall surface of the filter chamber 21 adjacent to the filter screen 221. Exemplarily, each filter screen 221 is arranged parallel to the YZ plane, and the filter inlet 211 and filter outlet 212 are respectively disposed on two opposite side walls of the filter chamber 21 along the Y direction. The air intake direction of the filter inlet 211 is parallel to the filter screen 221, so the hot air entering the filter chamber 21 will not directly impact the filter screen 221, and the flow through the filter screen 221 is relatively gentle, which is beneficial to achieving a better filtration effect.

[0050] In other embodiments, the filter inlet 211 and the filter outlet 212 may be disposed on the inner wall surface of the filter chamber 21 opposite to the filter screen 221, which can also achieve the purpose of discharging hot air into or out of the filter chamber 21.

[0051] In some embodiments, the preheating pipe 3 passes through each filtration zone 210 and abuts against the inner wall of the filtration chamber 21 within the filtration zone 210. This arrangement facilitates fixing the preheating pipe 3 to the inner wall of the filtration chamber 21, and when the preheating pipe 3 abuts against the filtration chamber 21, it also makes the installation of the preheating pipe 3 more secure.

[0052] Specifically, the filter assembly 22 also includes a fastener 222 for fixing the preheating pipe 3 and / or the filter screen 221 to the inner wall of the filter chamber 21.

[0053] Optionally, the fixing member 222 includes a U-shaped fixing clip, which fixes the preheating pipe 3 to the inner wall of the filter chamber 21 until it abuts against the inner wall. The fixing member 222 also includes a limiting plate, which is disposed on the bottom plate of the filter chamber 21 along the Z direction for fixing the filter screen 221. Specifically, a limiting groove is provided on the side of the limiting plate facing the filter screen 221, and the filter screen 221 is inserted into the limiting groove for fixing.

[0054] In some embodiments, please refer to... Figure 3 The hot gas filtration and recovery device 2 also includes an insulation layer 23, which is disposed on the outer side of the filter chamber 21. By setting the insulation layer 23 to insulate the filter chamber 21, the heat loss of the hot gas in the filter chamber 21 is reduced, thereby maintaining a good heating effect on the preheating pipe 3.

[0055] In some embodiments, the hot gas filtration and recovery device 2 further includes a negative pressure device (not shown in the figure), which is disposed at the filter exhaust port 212 to create a negative pressure in the filter exhaust port 212 to accelerate the airflow in the filter chamber 21, thereby improving the filtration efficiency.

[0056] Specifically, the negative pressure device can be a fan or other vacuum device that can create negative pressure at the filter exhaust port 212. No restrictions are placed on the specific structural form.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
