Description

Technical Field

[0001] This application belongs to the field of glass production technology, specifically relating to a cleaning device for the flue gas outlet of a glass kiln. Background Technology

[0002] In the glass manufacturing industry, regular cleaning of furnace flue openings is a crucial maintenance task. Because glass production typically involves high-temperature melting, a large amount of dust, slag, and other residues accumulate in the furnace flue openings. If these deposits are not cleaned promptly, they can not only affect the furnace's thermal efficiency but also cause flue blockages, thus affecting the furnace's normal operation and potentially leading to safety accidents. Therefore, to ensure the quality of glass production and the long-term stable operation of the furnace, regular cleaning of the furnace flue openings is essential.

[0003] In traditional flue cleaning operations, workers need to open the lower cleaning port of the flue to carry out the cleaning work. However, since the inside of the flue is usually under a slight positive pressure, once the cleaning port is opened, outside air will rush into the flue, causing drastic pressure fluctuations inside the furnace. These pressure fluctuations not only adversely affect the temperature control of the furnace but may also lead to defects in glass products during production, thereby reducing product quality. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a cleaning device for the flue gas outlet of a glass kiln, which solves the problem of pressure fluctuation inside the furnace caused by cleaning the flue gas outlet, and reduces the impact on the stability of the production process and product quality.

[0005] This application provides a cleaning device for the flue gas outlet of a glass furnace, comprising:

[0006] The piping assembly includes a pipe body and a first discharge gate valve disposed on the pipe body, the top of the pipe body being connected to the bottom of the kiln flue;

[0007] A flexible telescopic docking assembly is connected to the bottom of the pipe assembly;

[0008] The turnover box, when in use, is transferred to the bottom of the pipe assembly and sealed and connected by the elastic telescopic docking assembly.

[0009] In one possible implementation, the pipe assembly further includes a level gauge disposed on the pipe body for detecting the level of ash and slag collected within the pipe body.

[0010] In one possible implementation, the pipe assembly further includes a first visualization window disposed on the pipe body for observing the ash and slag collection within the pipe body.

[0011] In one possible implementation, the level gauge is located above the first discharge gate valve.

[0013] In one possible implementation, the piping assembly further includes a second discharge gate valve disposed on the pipe body, the second discharge gate valve being located above the level gauge or the first visualization observation window.

[0014] In one possible implementation, the pipe body includes a first vertical pipe and a second vertical pipe, the first discharge gate valve is disposed at the bottom end of the second vertical pipe, and the second discharge gate valve is disposed between the first vertical pipe and the second vertical pipe.

[0015] In one possible implementation, the second discharge gate valve includes a second movable gate plate inserted between the first vertical pipe and the second vertical pipe, and a second linear reciprocating drive connected to one end of the second movable gate plate.

[0016] In one possible implementation, the first discharge gate valve includes a first movable gate plate inserted at the bottom end of the second vertical pipe and a first linear reciprocating drive connected to one end of the first movable gate plate.

[0017] In one possible implementation, the piping assembly further includes a third flue gas inlet valve disposed between the kiln flue and the pipe body.

[0018] In one possible implementation, the third flue gas valve includes a third movable insert plate inserted between the kiln flue and the pipe body, and a third linear reciprocating actuator connected to one end of the third movable insert plate, wherein the third linear reciprocating actuator includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0019] In one possible implementation, the first linear reciprocating drive includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0022] In one possible implementation, the cleaning device further includes a conveyor mechanism and a positioning sensor, wherein the conveyor mechanism is used to move the turnover box and the positioning sensor is used to position the turnover box below the elastic telescopic docking assembly.

[0023] The beneficial effects of this application are as follows: By connecting the bottom of the kiln flue through a pipe assembly, ash and slag naturally fall through the pipe body to the transfer box at the bottom; the flexible telescopic docking assembly ensures a sealed connection between the transfer box and the pipe, preventing external air from entering the flue and maintaining a stable slightly positive pressure inside the furnace. This avoids pressure fluctuations caused by air intrusion during traditional cleaning, ensuring stable kiln temperature and product quality.

Detailed Implementation

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] like Figure 1-3As shown, this application provides a cleaning device for the flue gas outlet of a glass kiln, comprising: a pipe assembly 100, an elastic telescopic docking assembly 200, and a turnover box 300; wherein, the pipe assembly 100 includes a pipe body 110 and a first discharge gate valve 120 disposed on the pipe body 110, and the top of the pipe body 110 is connected to the bottom of the kiln flue 600; the elastic telescopic docking assembly 200 is connected to the bottom of the pipe assembly 100; in use, the turnover box 300 is transferred to the bottom of the pipe assembly 100 and sealed and connected by the elastic telescopic docking assembly 200.

[0030] Compared with existing technologies, the cleaning device for the glass kiln flue 600 provided in this application connects to the bottom of the kiln flue 600 via a pipe assembly 100. Ash and slag fall naturally through the pipe body 110 to the bottom transfer box 300. The elastic telescopic docking assembly 200 ensures a sealed connection between the transfer box 300 and the pipe, preventing external air from entering the flue and maintaining a stable slightly positive pressure inside the furnace. This avoids pressure fluctuations caused by air intrusion during traditional cleaning, ensuring stable kiln temperature and product quality. The detachable design of the transfer box 300 facilitates centralized cleaning and transportation of ash and slag, improving operational efficiency.

[0031] In one possible implementation, the pipeline assembly 100 further includes a level gauge 150 disposed on the pipe body 110 for detecting the level of ash and slag collected within the pipe body 110. The level gauge 150 monitors the ash and slag accumulation height within the pipe body 110 in real time, assisting in determining whether material discharge is necessary. The level gauge 150 enables automated monitoring, reducing manual intervention and improving safety.

[0032] In one possible implementation, the pipe assembly 100 further includes a first visual observation window 160 disposed on the pipe body 110 for observing the ash and slag collection within the pipe body 110. Manual observation of the ash and slag condition through the first visual observation window 160 assists in determining whether material discharge is necessary. The first visual observation window 160 provides dual protection and is suitable for flexible operation under complex working conditions.

[0033] In one possible implementation, the first visualization window 160 comprises high-temperature tempered glass.

[0034] In one possible implementation, the level gauge 150 is located above the first discharge gate valve 120. Positioning the level gauge 150 above the first discharge gate valve 120 ensures accurate measurement of the ash and slag quantity before discharge, preventing blockage due to excessive ash and slag during discharge. Optimizing the monitoring position improves the accuracy of discharge control and avoids wear caused by frequent opening and closing of the first discharge gate valve 120.

[0035] In one possible implementation, the first visualization window 160 is located above the first discharge gate valve 120. Positioning the first window above the first discharge gate valve 120 ensures accurate measurement of the ash and slag quantity before discharge, preventing blockage due to excessive ash and slag during discharge. This optimizes the monitoring position and improves the accuracy of discharge control. It also avoids wear caused by frequent opening and closing of the first discharge gate valve 120.

[0036] In one possible implementation, the piping assembly 100 further includes a second discharge gate valve 130 disposed on the pipe body 110, the second discharge gate valve 130 being located above the level gauge 150 or the first visual observation window 160. Adding the second discharge gate valve 130 above the level gauge 150 or the observation window creates a two-stage discharge control system. When the ash and slag reach a certain amount, the second discharge valve is first closed to isolate the upper ash and slag, and then the lower ash and slag are discharged through the first discharge valve. Segmented discharge reduces the impact on the micro-positive pressure of the flue gas duct, enhancing system stability. It also prevents excessive ash and slag accumulation from causing monitoring failure or pipe blockage.

[0037] In one possible implementation, the pipe body 110 includes a first vertical pipe 111 and a second vertical pipe 112. A first discharge gate valve 120 is located at the bottom end of the second vertical pipe 112, and a second discharge gate valve 130 is located between the first vertical pipe 111 and the second vertical pipe 112. The pipe body 110 is divided into a first vertical pipe 111 (connecting to the flue) and a second vertical pipe 112 (connecting to the turnover box 300). The second discharge gate valve 130 is located between the two vertical pipes, and the first discharge gate valve 120 is located at the bottom of the second vertical pipe 112. The flow of ash and slag is controlled in stages by two-stage valves. The segmented structure reduces the ash and slag falling speed, minimizes dust and pressure fluctuations, facilitates staged cleaning and maintenance, and extends equipment life.

[0038] In one possible implementation, the second discharge gate valve 130 includes a second movable gate plate 131 inserted between the first vertical pipe 111 and the second vertical pipe 112, and a second linear reciprocating actuator 132 connected to one end of the second movable gate plate 131. The second linear reciprocating actuator 132 drives the opening and closing of the second movable gate plate 131, enabling remote or automatic control of the valve's opening and closing. Automated operation reduces manual intervention and lowers the risk of operation in high-temperature environments. The second linear reciprocating actuator 132 provides stable thrust, ensuring valve sealing and reliability.

[0039] In one possible implementation, the first discharge gate valve 120 includes a first movable gate plate 121 inserted at the bottom end of the second vertical pipe 112 and a first linear reciprocating actuator 122 connected to one end of the first movable gate plate 121. The first linear reciprocating actuator 122 drives the opening and closing of the first movable gate plate 121, enabling remote or automatic control of the valve's opening and closing. Automated operation reduces manual intervention and lowers the risk of operation in high-temperature environments. The first linear reciprocating actuator 122 provides stable thrust, ensuring valve sealing and reliability.

[0040] In one possible implementation, the piping assembly 100 further includes a third flue gas inlet valve 140 disposed between the kiln flue 600 and the pipe body 110. The valve is closed during cleaning to isolate the flue from the cleaning device, preventing damage from slight positive pressure. This further isolates the device from external air, ensuring stable furnace pressure during cleaning and protecting the cleaning device from direct impact by high-temperature flue gas.

[0041] In one possible implementation, the third flue gas slide gate valve 140 includes a third movable slide gate 141 inserted between the kiln flue 600 and the pipe body 110, and a third linear reciprocating actuator 142 connected to one end of the third movable slide gate 141. The third linear reciprocating actuator 142 includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The opening and closing of the valve is achieved by driving the third movable slide gate 141 through the third linear reciprocating actuator 142, realizing remote or automatic control of the valve opening and closing. Automated operation reduces manual intervention and lowers the operational risks in high-temperature environments. The third linear reciprocating actuator 142 provides stable thrust, ensuring valve sealing and reliability. The third linear reciprocating actuator 142 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, flexibly configured according to the on-site power source conditions to adapt to the power environment (electric / pneumatic / hydraulic) of different factories, improving the applicability of the lifting device. Multiple types of actuators can be selected to meet different working conditions (such as explosion-proof and high-temperature resistant).

[0042] In one possible implementation, the first linear reciprocating drive 122 includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The first linear reciprocating drive 122 can be selected from an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and can be flexibly configured according to the on-site power source conditions to adapt to the power environment (electric / pneumatic / hydraulic) of different factories, improve the applicability of lifting devices, and allow for the selection of multiple types of drives to meet the needs of different working conditions (such as explosion-proof and high-temperature resistant).

[0043] In one possible implementation, the second linear reciprocating drive 132 includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The second linear reciprocating drive 132 can be selected from an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and can be flexibly configured according to the on-site power source conditions to adapt to the power environment (electric / pneumatic / hydraulic) of different factories, improve the applicability of lifting devices, and allow for the selection of multiple types of drives to meet the needs of different working conditions (such as explosion-proof and high-temperature resistant).

[0044] In one possible implementation, the elastic telescopic docking assembly 200 includes an elastic corrugated pipe 210 connected to the bottom end of the pipe body 110 and a hollow cover plate 220 connected to the bottom end of the elastic corrugated pipe 210. The hollow cover plate 220 is used to cover the top of the turnover box 300. The elastic corrugated pipe 210 and the hollow cover plate 220 form a telescopic docking structure that automatically adapts to the positional deviation of the turnover box 300, ensuring a sealed connection. This solves the positioning error problem of the turnover box 300, improves the docking success rate, and the elastic buffer of the corrugated pipe reduces mechanical wear and extends its service life.

[0045] In one possible implementation, the cleaning device further includes a conveyor-type transfer mechanism 400 and a positioning sensor 500. The conveyor-type transfer mechanism 400 is used to transfer the turnover box 300, and the positioning sensor 500 is used to position the turnover box 300 below the elastic telescopic docking assembly 200. The conveyor-type transfer mechanism 400 automatically transports the turnover box 300 to the area below the cleaning device, and the positioning sensor 500 ensures that the turnover box 300 accurately docks with the elastic telescopic assembly. Fully automated transfer reduces manual handling and improves operational efficiency, while precise sensor positioning prevents docking failure and ensures sealing.

[0046] This cleaning device, through its multi-stage valve control, flexible sealing connection, automated monitoring and transfer design, solves the problems of large furnace pressure fluctuations, low efficiency and many safety hazards during traditional flue cleaning, and significantly improves the production stability and maintenance convenience of glass kilns.

[0047] In one possible implementation, the hollow cover plate 220 has upward-sloping edges on both sides, so that when the transfer box is moved horizontally, the top of the transfer box contacts the sloped edges, causing the elastic bellows 210 to be compressed upward. Thus, after the transfer box is positioned, the hollow cover plate 220 is pressed more tightly against the top of the transfer box under the elastic restoring force of the elastic bellows 210, improving the sealing performance.

[0048] In one possible implementation, the bottom of the bend in the kiln flue 600 is connected to the top of the pipe body 110 via a flange. A large, closable cover plate 610 is provided on one side of the bend in the kiln flue 600, and a small, closable cover plate 630 is provided on the large cover plate 610. A second observation window 620 is provided on the small cover plate 630. By observing the flue blockage through the second observation window 620, the cleaning of the flue door or observation hole can be effectively selected, avoiding fluctuations in the kiln process and glass quality caused by frequent flue cleaning.
