Description

Technical Field

[0001] The utility model belongs to the technical field of substrate glass, and in particular relates to a cleaning device for condensate in a kiln flue. Background Art

[0002] In the production of substrate glass, the kiln is responsible for providing glass liquid with stable temperature, uniform composition and good melting quality for the subsequent processes.

[0003] The substrate glass is alkali-free glass. A certain proportion of boric acid / boric anhydride is introduced into the formula as a flux. The introduction of boric acid / boric anhydride is beneficial to improve the melting efficiency and ensure the melting quality. At the same time, it reduces the melting temperature and achieves the effect of extending the service life of the kiln. However, boric acid / boric anhydride has a certain degree of volatilization under high temperature conditions in the furnace, resulting in a high concentration of boron in the kiln flue gas, and condensates are easily formed in areas with lower temperatures, which block the flue, thereby affecting the stability of the process. To ensure process stability, the flue cleaning door needs to be opened regularly to manually clean the boron condensate in the flue. Opening and closing the flue cleaning door during each manual cleaning operation will cause certain fluctuations in the kiln pressure. The fluctuation of kiln pressure leads to an increase in bad bubbles, which has a greater impact on the yield of the production line. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a device for cleaning condensate in the flue of a kiln, which can solve the problem that the kiln pressure fluctuates due to the need to regularly open the flue cleaning door to manually clean the boron condensate in the flue, resulting in an increase in bad bubbles and a significant impact on the production line yield.

[0006] A flue body, the flue body comprising an upper extension section, a connecting section and a lower extension section arranged in sequence, the connecting section being laterally connected to the kiln, and the lower extension section being provided with a gate valve 1 and a gate valve 2 distributed up and down; and

[0007] At least one striking hammer arranged on the outside of the flue body is used to strike the flue body at a set frequency.

[0011] Optionally, an inspection door is provided on the outer side wall of the connecting section.

[0015] Optionally, the percussion hammer is a pneumatic hammer or an electric hammer.

[0016] Optionally, a plurality of striking hammers are distributed from top to bottom and symmetrically arranged on both sides of the flue body.

[0017] The beneficial effect of the utility model is that the percussion hammer on the outside of the flue of the kiln vibrates the flue by percussion, and the condensate attached to the flue is shaken off. Under normal circumstances, the gate plate 1 is in the open state and the gate plate 2 is in the closed state. When the flue gas condensate accumulates to a certain amount in the vertical flue, the percussion hammer is opened to start the flue gas condensate cleaning operation. After that, the gate plate 1 is slowly closed to isolate the connecting section from the lower extension section to prevent the external cold air from entering the kiln from the connecting section, greatly reducing the fluctuation of the kiln pressure and ensuring that the product is not affected. Then the gate plate 2 is slowly opened to allow the scattered flue gas condensate to fall through the lower extension section. After the flue gas condensate is discharged, the gate plate 2 is slowly closed, and the gate plate 1 is slowly opened to complete the flue gas condensate cleaning operation. It should be noted that the flue gas condensate contains boron condensate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1 and Figure 2As shown, the utility model provides a device for cleaning condensate in a kiln flue, comprising: a flue body 10 and at least one striking hammer 20 arranged on the outside of the flue body 10, the flue body 10 comprises an upper extension section 101, a connecting section 102 and a lower extension section 103 arranged in sequence, the connecting section 102 is laterally connected to the kiln, and the lower extension section 103 is provided with a gate valve 104 and a gate valve 2 105 distributed up and down; the striking hammer 20 is used to strike the flue body 10 at a set frequency.

[0022] Compared with the prior art, the utility model provides a device for cleaning condensate in the flue of the kiln. The hammer 20 on the outside of the flue of the kiln vibrates the flue by knocking the hammer 20, and the condensate attached to the flue is shaken off. Under normal circumstances, the gate 1 is in the open state and the gate 2 is in the closed state. When the flue gas condensate accumulates to a certain amount in the vertical flue, the hammer 20 is opened to start the cleaning of the flue gas condensate. After that, the gate 1 is slowly closed to isolate the connecting section 102 from the lower extension section 103, so as to prevent the external cold air from entering the kiln from the connecting section 102, greatly reducing the fluctuation of the kiln pressure and ensuring that the product is not affected. Then, the gate 2 is slowly opened to make the scattered flue gas condensate fall through the lower extension section 103. After the flue gas condensate is discharged, the gate 2 is slowly closed, and the gate 1 is slowly opened to complete the cleaning of the flue gas condensate. It should be noted that the flue gas condensate contains boron condensate.

[0023] In one embodiment, a collection box 30 is provided below the lower extension 103. Specifically, when the flue gas condensate scattered by knocking accumulates to a certain amount in the lower extension 103, the gate 1 is slowly closed, and then the gate 1 is slowly opened, so that the flue gas condensate passes through the lower extension 103 and falls into the collection box 30. When the collection box 30 is full of flue gas condensate, the worker moves the collection box 30 and pours the flue gas condensate into a designated location for storage, so as to prevent the flue gas condensate from falling randomly beside the kiln and improve the cleaning efficiency.

[0024] In one embodiment, an air cooling component 40 is provided on the outside of the flue body 10, and the gas blown out by the air cooling component 40 is directed to the striking hammer 20, so that the striking hammer 20 is cooled by air to ensure the normal operation of the air hammer. The cooling air can be taken from the low-temperature cooling air system of the production line air-conditioning system, or the air cooling component 40 includes a blower 401 and an air duct 402, and the outlet of the air duct 402 is located directly above the striking hammer 20.

[0025] In other embodiments, a condenser tube spirally surrounding the striking hammer 20 may be used, and cooling water may be passed through the condenser tube to provide a low-temperature operating environment for the striking hammer 20 , in place of the air cooling component 40 .

[0026] In one embodiment, an inspection door 106 is provided on the outer wall of the connecting section 102. Specifically, the connecting section 102 includes a rectangular tube and a transverse connecting pipe made of steel, the upper extension section 101 and the lower extension section 103 are respectively connected to the two ends of the rectangular tube by flanges or welding, the transverse connecting pipe is connected to the kiln, and the inspection door 106 is hinged or inserted on the outer side of the rectangular tube. The connecting section 102 is the part where the most flue gas condensate is gathered. Most of the time, the hammer 20 can remove the condensate on the flue body 10. In some special cases, it may be difficult to remove the residue, which can be completely removed by opening the inspection door 106.

[0027] Furthermore, a transparent observation port 107 is provided on the inspection door 106 . Specifically, a circular hole is opened on the inspection door 106 , and a high temperature resistant glass is fixedly provided in the circular hole, so that the accumulation of smoke condensate in the flue body 10 can be observed.

[0028] In one embodiment, the portion where the upper extension 101 is connected to the connecting section 102 is in the shape of an inverted funnel, and the portion where the lower extension 103 is connected to the connecting section 102 is in the shape of a funnel. Specifically, the upper extension 101 is a closed structure from bottom to top, which can reduce contact with the outside air and ensure that the temperature in the kiln is sufficiently stable. The lower extension 103 is a closed structure from top to bottom, which makes it easier for the smoke condensate to fall into the collection box 30 and reduces the probability of spilling. In other embodiments, the upper extension 101 is a straight cylinder.

[0029] In one embodiment, the distance between the lower extension section 103 and the kiln is no more than 30 cm. Preferably, the distance between the lower extension section 103 and the kiln is no more than 10-20 cm.

[0030] In this embodiment, the striking hammer 20 is a pneumatic hammer or an electric hammer.

[0031] In one embodiment, a plurality of percussion hammers 20 are distributed from top to bottom and symmetrically arranged on both sides of the flue body 10. Specifically, one or more percussion hammers 20 are designed on the left and right sides and at different heights above and below the flue body 10, and the percussion hammers 20 symmetrically percuss and vibrate the side wall of the flue body 10 to make the condensate attached to the flue fall off, which not only improves the efficiency of removing the flue gas condensate, but also reduces the probability of the flue body 10 being offset relative to the kiln due to the percussion vibration.
