Technical Field

[0001] The present disclosure relates to the technical field of kilns, and particularly to a dust cleaning device for a pressure regulating chimney in the working section of a float glass kiln. Background Art

[0002] The general structure of a float glass kiln consists of a regenerator, a large kiln, a neck, a cooling section, etc.; among them, the cooling section is responsible for further cooling and homogenizing the molten glass that has been melted and clarified in the large kiln, so as to deliver the high-quality molten glass we want to the forming area; that is to say, the cooling section plays a bridging role. The cooling section mainly includes a cooling pond and a pressure regulating chimney device on both sides of the cooling pond. We know that the pressure regulating chimneys on both sides of the cooling pond are used to adjust the internal pressure of the cooling section, and maintaining the stability of the kiln pressure is an important item among the "four small stabilities" in this industry; the regulation of the kiln pressure in the working section of the cover glass kiln is usually manually completed by controlling the opening degree of the pressure regulating chimney covers on both sides of the working pond. When the process requires or the kiln pressure becomes unstable due to fluctuations in process parameters, we need to manually adjust the opening degree of the pressure regulating chimney covers in the cooling section to maintain the kiln pressure stability in the cooling section.

[0003] However, in the existing operation process, dust and impurities may be introduced into the chimney, or the temperature may be unstable, and the kiln pressure may be unstable, etc., all of which may cause dust and debris to fall into the pressure regulating chimney. At the same time, the existing operation method may cause the kiln pressure to be unstable when cleaning the dust, which is not conducive to the process.

[0029] Embodiments

[0030] As Figures 1 to 2 As shown, a dust cleaning device for a pressure regulating chimney in the working section of a float glass furnace provided by a basic embodiment of the present application, the pressure regulating chimney includes a chimney main body 3 and a support platform 7 arranged below the chimney main body 3. The inner cavity of the chimney main body 3 is used to connect the cooling section; a dust cleaning mechanism 5 is arranged at the lower part of the chimney main body 3. The dust cleaning mechanism 5 penetrates through the support platform 7. The dust cleaning mechanism 5 includes a collection port and a discharge port arranged up and down. A dust cleaning channel is formed between the collection port and the discharge port for discharging dust or impurities in the chimney main body 3; and a slide gate valve 6. At least two slide gate valves 6 are arranged in the dust cleaning channel in an up-and-down arrangement.

[0031] To facilitate understanding of the technical solution of the dust cleaning device for the pressure regulating chimney in the working section of the float glass furnace of the present application, the following will specifically illustrate the technical effects of the dust cleaning device for the pressure regulating chimney in the working section of the float glass furnace of the present application in conjunction with the accompanying drawings.

[0032] As Figure 1 As shown, the pressure regulating chimney includes a chimney main body 3 and a support platform 7 arranged at the lower part of the pressure regulating chimney main body 3. The support platform 7 is used to support the pressure regulating chimney. The inner cavity of the chimney main body 3 is used to connect the cooling section. A dust cleaning mechanism 5 is arranged at the lower part of the chimney main body 3. Among them, the dust cleaning mechanism 5 includes a collection port and a discharge port arranged up and down. A dust cleaning channel is formed between the collection port and the discharge port. Dust or impurities in the inner cavity of the chimney main body 3 are discharged through the dust cleaning channel. At least two slide gate valves 6 are arranged in the dust cleaning channel in an up-and-down arrangement. Specifically, two slide gate valves 6 are arranged up and down in the dust cleaning channel. First, the slide gate valve 6 on the upper side of the dust cleaning channel is opened, and the slide gate valve 6 on the lower side is closed. Dust deposits on the slide gate valve 6 on the lower side of the dust cleaning channel. After the dust deposits to a certain extent, the upper side slide gate valve 6 is closed, and the lower side slide gate valve 6 is opened, ensuring that when the dust in the chimney main body 3 is discharged, the kiln pressure in the chimney main body 3 is stable, ensuring the process stability and improving the product quality.

[0033] In some embodiments, as Figure 1As shown in the figure, an internal chimney 9 is provided above the chimney main body 3. The internal chimney 9 is used to connect the inner cavity of the chimney main body 3 with the external air. One end of the internal chimney 9 connecting to the external air is provided with an external chimney 1 connecting to an environmental protection desulfurization and denitration device. Optionally, the internal chimney 9 and the external chimney 1 are made of steel. Connecting the external chimney 1 to the environmental protection desulfurization and denitration device can purify the discharged smoke before it is released into the air, which is safe and environmentally friendly. At the same time, the internal chimney 9 is provided with an adjustable mechanism for adjusting the opening degree of the port connecting to the external air. By controlling the opening degree of the port of the internal chimney 9 through the adjustable mechanism, the kiln pressure in the chimney main body 3 can be controlled, ensuring the stability of the kiln pressure, guaranteeing the stability of the process, and improving the product quality.

[0034] In some embodiments, the adjustable mechanism is a pressure regulating cover 2 provided on the port of the internal chimney 9 connecting to the external air. The operator can adjust the opening degree of the port of the internal chimney 9 connecting to the external air by adjusting the pressure regulating cover 2, thereby independently adjusting the kiln pressure, guaranteeing the stability of the process, and improving the product quality.

[0035] In some embodiments, the dust cleaning mechanism 5 includes a collecting funnel. The upper and lower openings of the collecting funnel are a collecting port and a discharging port respectively. The collecting port collects the dust in the chimney main body 3 and discharges it through the discharging port. At the same time, the dust cleaning mechanism is funnel-shaped, which is convenient for the collection and discharge of dust, improves the dust cleaning efficiency, guarantees the stability of the process, and improves the product quality.

[0036] In some embodiments, the collecting funnel is arranged directly below the inner port of the internal chimney 9 located in the inner cavity of the chimney main body 3, so that when the pressure regulating cover 2 is adjusted, the external dust can directly fall into the collecting funnel, preventing the dust from entering the cooling part and polluting the glass liquid, guaranteeing the stability of the process, and improving the product quality.

[0037] In some embodiments, the collecting port of the collecting funnel is higher than the bottom of the inner cavity of the chimney main body 3, so that the soot in the chimney main body 3 can more easily fall into the collecting funnel, preventing the dust from entering the cooling part and polluting the glass liquid, guaranteeing the stability of the process, and improving the product quality.

[0038] In some embodiments, the bottom of the inner cavity of the chimney main body 3 is a horizontal plane, so that the collecting port of the collecting funnel is higher than the bottom of the inner cavity of the chimney main body 3, ensuring that when the pressure regulating cover 2 is adjusted, the dust entering the chimney main body 3 can fall into the collecting funnel, preventing the dust from entering the cooling part and polluting the glass liquid, guaranteeing the stability of the process, and improving the product quality.

[0039] In some embodiments, the central axes of the inner chimney 9, the outer chimney 1, and the collection funnel are collinear. When the operator adjusts the pressure regulating cover 2 on the external air port connected to the inner chimney 9, dust will enter the chimney main body 3 through the inner chimney 9. The collinearity of the central axes of the inner chimney 9, the outer chimney 1, and the collection funnel allows the dust to directly fall into the collection funnel, preventing the dust from entering the cooling section through the chimney main body 3 and contaminating the glass liquid, ensuring the process stability and improving the product quality.

[0040] In some embodiments, the collection funnel is in an inverted conical shape. The upper opening of the collection funnel, i.e., the collection port, is the opening with a larger diameter, and the lower opening of the collection funnel, i.e., the discharge port, is the opening with a smaller diameter. This can make it easier for the dust to fall into the collection funnel, prevent the dust from entering the cooling section through the chimney main body 3 and contaminating the glass liquid, ensure the process stability and improve the product quality.

[0041] In some embodiments, the chimney main body 3 includes the main chimney railing 8 located in the upper part. The inner chimney 9 is installed on the main chimney railing 8, and the inner chimney 9 communicates with the chimney main body 3. The main chimney railing 8 can be used to protect the chimney main body 3 from cracking due to thermal expansion, improve the stability of the pressure regulating chimney, ensure the process stability and improve the product quality.

[0042] In some embodiments, an observation hole 4 is provided on the chimney main body 3. By observing the deposition degree of dust in the chimney main body 3 through the observation hole 4, it is convenient for the staff to operate.

[0043] To facilitate a more profound understanding of the technical concept and advantages of the dust cleaning device for the pressure regulating chimney in the working section of the float glass furnace of the present application, the following combines Figures 1 to 2 to describe the structural form of the dust cleaning device for the pressure regulating chimney in the working section of the float glass furnace with relatively comprehensive preferred features of the present application.

[0044] The pressure-regulating chimney includes a chimney main body 3 and a support platform 7 provided below the pressure-regulating chimney main body 3. The support platform 7 is used to support the chimney main body 3. The inner cavity of the chimney main body 3 is used to connect the cooling part, and the bottom of the inner cavity of the chimney main body 3 is a horizontal plane. A dust cleaning mechanism 5 is provided at the lower part of the chimney main body 3. Among them, the dust cleaning mechanism 5 includes a collection port and a discharge port arranged vertically. The collection port is higher than the bottom of the inner cavity of the chimney main body 3. A dust cleaning channel is formed between the collection port and the discharge port. The dust cleaning mechanism 5 includes a collection funnel. The upper and lower openings of the collection funnel are respectively the collection port and the discharge port, and the shape is an inverted cone. The collection port collects the dust in the chimney main body 3 and discharges it through the discharge port. At the same time, the dust cleaning mechanism is funnel-shaped. The collection funnel is arranged directly below the inner port of the inner connecting chimney 9 located in the inner cavity of the chimney main body 3. At least two slide gate valves 6 are arranged vertically in the dust cleaning channel. Specifically, two slide gate valves 6 are arranged vertically in the dust cleaning channel. First, open the slide gate valve 6 on the upper side of the dust cleaning channel and close the slide gate valve 6 on the lower side. The dust deposits on the slide gate valve 6 on the lower side of the dust cleaning channel. After the dust deposits to a certain extent, close the upper slide gate valve 6 and open the lower slide gate valve 6 to ensure that the kiln pressure in the chimney main body 3 is stable when discharging the dust in the chimney main body 3. An inner connecting chimney 9 is provided above the chimney main body 3. The inner connecting chimney 9 is used to connect the inner cavity of the chimney main body 3 with the external air. One end of the inner connecting chimney 9 connecting the external air is provided with an external connecting chimney 1 connecting an environmental protection desulfurization and denitration device. The inner connecting chimney 9 and the external connecting chimney 1 are made of steel. Connecting the external connecting chimney 1 to the environmental protection desulfurization and denitration device can purify the discharged smoke before it is released into the air. At the same time, the adjustable mechanism is a pressure-regulating cover 2 arranged at the port of the inner connecting chimney 9 connecting the external air. The operator adjusts the pressure-regulating cover 2 to adjust the opening degree of the port of the inner connecting chimney 9 connecting the external air, thereby independently adjusting the kiln pressure. The central axes of the inner connecting chimney 9, the external connecting chimney 1 and the collection funnel are collinear. The chimney main body 3 includes a main chimney railing 8 located in the upper part. The inner connecting chimney 9 is installed on the main chimney railing 8, and the inner connecting chimney 9 communicates with the chimney main body 3. The main chimney railing 8 can be used to protect the chimney main body 3 from cracking due to thermal expansion, improving the stability of the pressure-regulating chimney. An observation hole 4 is provided on the chimney main body 3 to observe the deposition degree of the dust in the chimney main body 3 through the observation hole 4, which is convenient for the staff to operate.

[0045] It can be seen from the above description of the present disclosure that a dust cleaning mechanism 5 is provided at the lower part of the chimney main body 3. Two slide gate valves 6 are arranged vertically in the dust cleaning mechanism 5. At the same time, an inner connecting chimney 9 is provided on the chimney main body 3, and a pressure-regulating cover 2 is provided on the inner connecting chimney 9 to adjust the internal kiln pressure of the chimney main body 3. After the dust deposits to a certain extent, close the upper slide gate valve 6 and open the lower slide gate valve 6 to ensure that the kiln pressure in the chimney main body 3 is stable when discharging the dust in the chimney main body 3, ensuring the process stability and improving the product quality.
