The invention will be described in further detail with reference to the drawings and specific examples.
As shown in fig. 1 to 4, the kiln exhaust chimney of the embodiment includes a chimney main pipe 1 vertically arranged, the chimney main pipe 1 is laterally connected with an air outlet of a fan 3 through a chimney auxiliary pipe 2, and an air inlet of the fan 3 is connected with a kiln 5 through a tail gas conveying assembly 4; tail gas in the kiln 5 sequentially passes through the tail gas conveying assembly 4, the fan 3 and the chimney secondary pipe 2, enters the chimney main pipe 1 and is discharged from the top opening. In the prior art, the fan 3 is arranged at the bottom side of the chimney main pipe 1, the air outlet is connected with the chimney main pipe 1, the air inlet is connected with the tail gas conveying component 4, and the tail gas in the kiln 5 input by the tail gas conveying component 4 is discharged from the top end opening of the chimney main pipe 1 through blowing. The tail gas in the kiln 5 contains dust, and in the process that the tail gas passes through the chimney main pipe 1, part of the dust collides with the inner wall of the chimney main pipe 1 to form adhesion, and after the dust is accumulated for a long time, a large amount of dust is collected into an integrated block, and under the action of self gravity and wind disturbance, the dust block possibly falls off from the inner wall of the chimney main pipe 1 and is directly hit to the fan 3 located right below, so that the normal operation of the fan 3 is influenced, and even the fan is damaged. Moreover, the gas temperature change under the start/stop state of the kiln 3 is strong, and when the gas inside the chimney main pipe 1 is cooled and condensed and is gathered on the inner wall, the gas drips under the action of gravity to enter the fan 3, or the external rainwater drifts into the chimney main pipe 1 to drip into the fan 3, so that the service life of the fan 3 is influenced. The secondary chimney pipe 2 communicated with the primary chimney pipe 1 is arranged in the lateral direction of the primary chimney pipe 1, the air inlet end of the secondary chimney pipe 2 is connected with the fan 3, tail gas blown out by the fan 3 can be sent into the primary chimney pipe 1 through the secondary chimney pipe 2, the mounting position of the fan 3 is shifted to the lateral direction from the position right below the primary chimney pipe 1 under the condition that exhaust is not affected, and then dust blocks and liquid in the primary chimney pipe 1 can be effectively prevented from falling into the fan 3. Compared with the prior art, the utility model provides a technical scheme can be through the mounted position who changes fan 3 avoid the chimney to be responsible for the solid or the liquid junk in 1 to form the protection to fan 3.
In this embodiment, a discharge opening 11 is formed at the bottom end of the chimney main pipe 1, and an opening and closing mechanism 12 is installed at the discharge opening 11. The dust block that the chimney main pipe 1 inner wall drops to and the liquid that condenses or wafts into pile up in the chimney main pipe 1 bottom, in order to can discharge it in order to avoid influencing the normal use of chimney main pipe 1, be equipped with bin outlet 11 in chimney main pipe 1 bottom. Simultaneously, in order to make things convenient for opening and shutting of bin outlet 11, can be in the mechanism that can open and shut of 11 departments of bin outlet installation, for example valve, blind plate or pipe cap, when the dregs of a decoction of needs discharge, only need adjust to open and shut the mechanism to the open mode, treat to arrange the sediment completion after, adjust to open and shut the mechanism to the closed mode can.
In this embodiment, the top opening of the chimney main pipe 1 is provided with a rain-proof cap 13. When the kiln 5 is installed in an indoor environment, the top end of the chimney main pipe 1 needs to extend out of a roof to discharge tail gas to the outside. The rain-proof cap 13 is arranged at the opening at the top end of the chimney main pipe 1, so that rainwater can be effectively prevented from dripping into the chimney main pipe 1, and therefore water vapor in the pipe is reduced, and corrosion is reduced.
In this embodiment, the chimney sub-pipe 2 is disposed obliquely, and the upper end is connected to the chimney main pipe 1, and the lower end is connected to the air outlet of the fan 3. The exhaust gas is discharged from the opening at the top end of the main pipe 1 of the chimney, and after the secondary pipe 2 of the chimney is obliquely arranged, the exhaust gas enters from the lower end and flows out from the upper end, and enters the main pipe 1 of the chimney in an obliquely upward manner, so that the exhaust gas can flow in the main pipe 1 of the chimney in a rising state until being discharged from the opening at the top end.
In this embodiment, the tail gas conveying assembly 4 includes an induced air pipe 41, a tail gas main pipe 42 and a tail gas branch pipe 43 which are sequentially communicated; the air outlet end of the induced draft pipe 41 is connected with the fan 3, and the air inlet end of the tail gas branch pipe 43 is connected with the kiln 5. The main tail gas pipe 42 is arranged along the length direction of the kiln 5, a plurality of branch tail gas pipes 43 are connected to the main tail gas pipe in a lateral direction at intervals, and the air inlet end of each branch tail gas pipe 43 is connected with the kiln 5. The kiln 5 may be provided with a plurality of hearths arranged in a row according to functional requirements, and tail gas generated in different hearths needs to be discharged, so that a plurality of tail gas branch pipes 43 are arranged, and each tail gas branch pipe 43 is communicated with one hearth to discharge tail gas therein. And through the arrangement of the tail gas main pipe 42 arranged along the length direction of the kiln 5, each tail gas branch pipe 43 is connected with the tail gas main pipe 42, so that tail gas exhausted from each hearth can be collected to the tail gas main pipe 42 and sent to the fan 3 through the air guiding pipe 41.
