Description

Technical Field

[0001] This utility model relates to the field of tunnel kiln technology, specifically to a high-temperature tunnel kiln flue gas extraction structure. Background Technology

[0002] A tunnel kiln is a modern, continuous firing thermal equipment constructed from refractory, insulation, and building materials. Its shape resembles a tunnel, and it contains kiln cars and other transport vehicles. During operation, tunnel kilns typically generate a large amount of high-temperature flue gas. If this flue gas is not extracted and purified, it can easily cause serious environmental pollution. Therefore, developing a high-temperature tunnel kiln flue gas extraction structure is of significant practical importance in order to improve this situation.

[0003] A high-temperature tunnel kiln flue gas extraction structure, referenced in announcement number CN221099385U, includes a recovery mechanism. The inlet of the recovery mechanism is connected to a filter mechanism. The filter mechanism contains a cleaning mechanism, which includes a rotating shaft and vertical rods. The rotating shaft is rotatably mounted on the rear side of the inner wall of the filter mechanism. A wind turbine blade assembly is fixedly mounted on the outside of the rotating shaft. A turntable is fixedly mounted on the front of the rotating shaft. Two vertical rods are fixedly mounted on the bottom wall of the filter mechanism. This high-temperature tunnel kiln flue gas extraction structure, through the arrangement of the cleaning and filtering mechanisms, allows the flue gas to... Solid particulate matter is intercepted to minimize its adhesion to the interior of the waste heat recovery unit, ensuring its effectiveness. Simultaneously, the cleaning mechanism can remove dust from the filter screen during flue gas filtration, maintaining the filtration efficiency and further guaranteeing the flue gas heat exchange effect. However, while this flue gas extraction structure can be effectively used to extract and purify high-temperature flue gas generated by tunnel kilns, it is often difficult to clean the filter screen by brushing. This allows particulate matter in the flue gas to easily adhere to the filter screen surface, causing blockage and frequently troubling users. Utility Model Content

[0004] The purpose of this utility model is to provide a high-temperature tunnel kiln flue gas extraction structure to solve the problem that although the flue gas extraction structure proposed in the background art can be well applied to extract and purify the high-temperature flue gas generated by the tunnel kiln, it is usually not convenient to brush and clean the filter screen components, which makes the particulate matter in the flue gas easily adhere to the surface of the filter screen and cause the filter screen to become clogged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature tunnel kiln flue gas extraction structure, comprising a base, a waste heat recovery device on one side of the top of the base, a purification box on the top of the base on one side of the waste heat recovery device, an exhaust pipe on the outer wall of one side of the purification box, the end of the exhaust pipe away from the purification box being connected to the outer wall of the waste heat recovery device, a filter screen installed at the upper end of the interior of the purification box, a strip plate on the upper end of the surface of the purification box, a telescopic drive component mounted on one side of the top of the strip plate via a bracket, a bearing seat at one end of the telescopic drive component, a brush plate at the top of the bearing seat, one end of the brush plate extending into the interior of the purification box and contacting the bottom end of the filter screen, an air inlet pipe on the outer wall of the waste heat recovery device away from the exhaust pipe, two extraction mechanisms on the top of the base on one side of the air inlet pipe, a support frame on one side of the top of the base, an electrical control box at the top of the support frame, and an output terminal of a single-chip microcomputer inside the electrical control box being electrically connected to the input terminal of the telescopic drive component.

[0006] Preferably, a limiting rail is provided at the center of the top of the strip plate, and a rail seat is slidably connected to one side of the top of the limiting rail. The top of the rail seat is fixedly connected to the bottom of the bearing seat. The setting of the rail seat and the limiting rail is used to limit the movement range of the bearing seat.

[0007] Preferably, the air extraction mechanism includes a mounting base, and two mounting bases are provided at the top of the base on one side of the air inlet pipe. The mounting bases are provided to accommodate the exhaust fan and the rotary drive component.

[0008] Preferably, the exhaust mechanism includes an exhaust fan and a rotary drive. An exhaust fan is provided on one side of the top of the component seat, and a rotary drive is installed on the top of the component seat on the side of the exhaust fan via a bracket. One end of the rotary drive is connected to the outer wall of the exhaust fan. The rotary drive drives the exhaust fan to operate so as to extract and process the flue gas in the tunnel kiln.

[0009] Preferably, the air extraction mechanism includes a first air extraction pipe and a first valve fitting. The top of the exhaust fan is provided with the first air extraction pipe, and the end of the first air extraction pipe away from the exhaust fan is equipped with the first valve fitting. The first valve fitting is provided so that the first air extraction pipe can be opened and closed.

[0010] Preferably, the air extraction mechanism includes a second air extraction pipe and a second valve fitting. The second air extraction pipe is provided on the outer wall of the exhaust fan away from the rotating drive component.

The end of the second valve fitting away from the second air extraction pipe is connected to the outer wall of the air inlet pipe. The second valve fitting is provided to allow the second air extraction pipe to be opened and closed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the high-temperature tunnel kiln flue gas extraction structure not only reduces the phenomenon of filter screen clogging, but also ensures the continuity of high-temperature flue gas extraction in the tunnel kiln when the flue gas extraction structure is used, and improves the energy saving and environmental protection of the flue gas extraction structure when it is used.

[0012] (1) The carrier seat is moved horizontally by the telescopic drive component, so that the carrier seat moves the rail seat to the top of the limit rail and slides, so that the carrier seat moves the brush plate smoothly into the purification box. The brush plate can then brush and clean the lower surface of the filter screen to clean the particulate matter attached to the lower surface of the filter screen, thereby reducing the phenomenon of filter screen clogging.

[0013] (2) By setting up two extraction mechanisms, one of the extraction mechanisms can extract and process the high-temperature flue gas in the tunnel kiln. When the first extraction mechanism stops extracting flue gas due to a malfunction, the second extraction mechanism can be immediately switched to extract the flue gas in the tunnel kiln, thereby ensuring the continuity of the extraction of high-temperature flue gas in the tunnel kiln when the flue gas extraction structure is in use.

[0014] (3) The high-temperature flue gas in the tunnel kiln is extracted into the air inlet pipe by the air extraction mechanism so that the high-temperature flue gas first flows into the waste heat recovery unit for heat exchange and recovery. After heat exchange and recovery, the flue gas flows into the purification box through the exhaust pipe. The flue gas is filtered and purified by the filter screen and then discharged from the air outlet at the top of the purification box, thereby achieving the purpose of heat exchange, recovery and purification of high-temperature flue gas, thus improving the energy saving and environmental protection of the flue gas extraction structure.
