Description

Technical Field

[0001] This utility model belongs to the field of exhaust pipes for heating furnaces, and relates to an auxiliary device for exhaust pipes for heating furnaces. Background Technology

[0002] The main function of auxiliary devices for heating furnace exhaust pipes is to purify waste gas, reduce the emission of harmful substances, and protect the environment and human health. During the operation of the heating furnace, a large amount of waste gas is generated. This waste gas may contain pollutants such as particulate matter and harmful gases. If it is directly discharged into the atmosphere, it will cause serious harm to the environment and human health. Therefore, auxiliary purification devices for heating furnace exhaust pipes have emerged.

[0003] A heating furnace piping structure, disclosed in publication number CN221075684U, relates to the field of heating furnace piping technology. This application includes a piping body, and further includes: a pre-installed plate connected to the heating furnace; a connector installed on the piping body for connecting to the pre-installed plate; and a support member installed on the connector, which supports the piping body and connector after the connector connects the piping body to the heating furnace. This application first installs the pre-installed plate on the heating furnace, then connects the piping body to the furnace via the connector, and finally connects the piping body to the pre-installed plate via the connector, supporting the piping body with the support member. This increases the stability of the piping body during use, thereby reducing the potential danger of detachment due to aging.

[0004] While the above technical solution increases the stability of the pipeline body during use and reduces the possibility of danger when the pipeline body ages and falls off, it is not convenient to cool and filter the exhaust pipeline. Since most of the flue gas discharged from the heating furnace is at high temperature, the service life of the exhaust pipeline is easily reduced if it is not cooled in time. Utility Model Content

[0005] The technical problem to be solved by this utility model is that it is not convenient to cool and filter the flue gas discharged from the exhaust pipe. Since most of the flue gas discharged from the heating furnace is at high temperature, the service life of the exhaust pipe is easily reduced if it is not cooled in time. To overcome the shortcomings of the prior art, an auxiliary device for the exhaust pipe of the heating furnace is provided.

[0006] This utility model includes a heating furnace, an exhaust pipe is provided on the upper part of the heating furnace, a heat dissipation component is fixedly connected to the surface of the exhaust pipe, and a filter component is connected to the upper part of the exhaust pipe.

[0007] The heat dissipation assembly includes two positioning rings. Connecting rods are fixedly connected to both sides of the inner cavity of the positioning rings. Heat dissipation fins are fixedly connected to the surface of the connecting rods. The heat dissipation fins are fixedly connected to the surface of the exhaust pipe. The lower part of one of the positioning rings is fixedly connected to the upper part of the heating furnace.

[0008] The filter assembly includes a conveying pipe, a filter box connected to the lower right side of the conveying pipe, a filter screen and ceramic fiber inside the filter box, a positioning plate movably connected to the upper part of the filter box, the upper part of the filter screen being fixedly connected to the lower part of the positioning plate, the ceramic fiber being fixedly connected to the lower right side of the positioning plate, and the conveying pipe being connected to the upper part of the exhaust pipe.

[0009] The filter box is connected to a filter barrel on the right side, and a motor is fixedly connected to the right side of the filter barrel. A first gear is fixedly connected to the output shaft of the motor, and a second gear is meshed with the front side of the first gear. A rotating shaft is fixedly connected to the inner cavity of the second gear, and the rotating shaft passes through the second gear. The inner cavity of the rotating shaft is hollow.

[0010] A rotary joint is movably connected to the right side of the rotating shaft, and a connecting pipe is movably connected to the inner cavity of the rotary joint. The connecting pipe passes through the filter barrel, and a connecting flange is fixedly connected to the front side of the connecting pipe. A spray head is fixedly connected to the surface of the rotating shaft.

[0011] The rotating shaft surface is movably connected to a limiting frame via a bearing. The upper part of the limiting frame is fixedly connected to the inner wall of the filter barrel. An air outlet pipe is connected to the upper part of the filter barrel. A limiting plate is fixedly connected to the surface of the air outlet pipe. The lower part of the limiting plate is fixedly connected to the upper part of the filter barrel. A cleaning plate is fixedly connected to the rotating shaft surface. The cleaning plate slides in contact with the inner wall of the filter barrel. A water trough is provided at the lower part of the filter barrel.

[0012] The lower part of the heating furnace is fixedly connected to a support frame, and the lower part of the filter box is fixedly connected to a support base. The upper right side of the support base is fixedly connected to the lower part of the filter barrel.

[0013] Working process or principle: When the heating furnace discharges gas, the flue gas inside the furnace is transported to the exhaust pipe. Because the flue gas contains high temperatures, this heat is transferred to the exhaust pipe. The heat dissipation fins on the surface of the exhaust pipe dissipate this heat, preventing damage to the exhaust pipe from continuous high temperatures. When it is necessary to filter harmful substances from the flue gas, the motor is started. The motor drives the first gear to rotate, which in turn drives the second gear. When the second gear rotates, it drives the shaft to rotate, thus filtering the flue gas. The flue gas is transported through a pipeline to the inside of the filter box, where the filter screen and ceramic fibers filter out harmful substances. The filtered flue gas is then transported from the filter box to the inside of the filter barrel, where it is connected to a water pipe using existing technology via a connecting flange. Water is then transported from the water pipe to the inside of the connecting pipe, and from the connecting pipe to the inside of the rotating shaft. The rotating shaft then transports the water to the inside of the spray head, where it sprays water to filter out water-soluble harmful substances in the flue gas. Finally, the filtered flue gas is discharged to the outside of the equipment through the exhaust pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the above-mentioned structure in combination, this utility model has the following beneficial effects: when this device is in use, it can cool down the exhaust pipe body to avoid damage to the exhaust pipe body caused by continuous high temperature, and this device can also filter harmful substances in the flue gas.
