Description

Technical Field

[0001] The utility model relates to the technical field of kilns, in particular to a kiln chimney. Background Art

[0002] In order to prevent the gas in the kiln from polluting the atmosphere when it is discharged, it is usually necessary to add a gas filter component in the chimney to achieve the purpose of filtering the gas. However, the existing chimney still has some shortcomings:

[0003] 1. The existing chimney is usually equipped with multiple layers of filters. When the bottom layer of filters needs to be replaced, the multiple layers of filters usually need to be removed and then installed in sequence inside the chimney after replacement. The operation steps are numerous and the efficiency is low.

[0004] 2. Due to the high pressure and temperature of the gas in the kiln, when it is discharged from the chimney for a long time, it may cause the filter to shift and deform, resulting in the gas being discharged from the chimney through the gap between the filter and the inner wall of the chimney without being filtered, thus causing pollution to the atmosphere.

[0008] More preferably, the mounting ring is symmetrically provided with a slide groove along the thickness direction on one side close to the mounting plate, an elastic telescopic rod is fixed in the slide groove, a lifting block sliding along the slide groove is fixed on the top of the elastic telescopic rod, a slide rail is fixed along the thickness direction at the corresponding positions of the limit plate and the lifting block, a slider adapted to the lifting block is slidably connected in the slide rail; the top of the lifting block extends into the inside of the slide rail and abuts against the bottom of the slider.

[0009] More preferably, a guide plate group is fixedly provided on the inner wall of the chimney away from the guide groove and at positions corresponding to several mounting rings. The guide plate group includes two guide plates arranged along the circumferential direction of the inner wall of the chimney. The two guide plates are respectively located on both sides of the mounting ring and are close to each other and abut against the filter screen.

[0022] A kiln chimney comprises a chimney 1 body and a plurality of filter assemblies 2 arranged at intervals inside the chimney 1 along the length direction of the chimney 1; the outer wall of the chimney 1 is provided with guide grooves 11 corresponding to the plurality of filter assemblies 2, and one end of the guide groove 11 is rotatably connected to a rotating shaft 12 fixed to the filter assemblies 2; each group of the filter assemblies 2 comprises a mounting plate 21 fixedly connected to the rotating shaft 12, a limiting plate 22 symmetrically fixed to the upper and lower sides of the inner wall of the mounting plate 21, a mounting ring 23 arranged between the two limiting plates 22 and detachably connected to the limiting plates 22 at both ends, and a filter screen 24 fixed in the mounting ring 23; a limiting groove 13 is provided at one end of the guide groove 11 away from the rotating shaft 12, and an elastic limiting block 211 corresponding to the limiting groove 13 is fixed on the mounting plate 21, and the elastic limiting block 211 is interference fit with the limiting groove 13.

[0023] Through the cooperation of multiple filter components 2 and guide grooves 11, the filter screen 24 in a single filter component 2 can be replaced, avoiding the situation where multiple filter screens 24 need to be taken out before replacement when the bottom filter screen 24 needs to be replaced, simplifying the steps of replacing the filter screen 24 and improving the replacement efficiency; through the cooperation of the mounting plate 21, the limiting plate 22, the mounting ring 23 and the filter screen 24, the filter screen 24 can be quickly disassembled, and at the same time, the limiting plate 22 limits the filter screen 24 to avoid the filter screen 24 from shifting in the chimney 1 due to the impact of gas, etc., thereby improving the firmness of the filter screen 24 and preventing the gas from being discharged from the gap between the chimney 1 and the filter component 2, thereby avoiding air pollution.

[0024] As a possible implementation of the present scheme, preferably, the mounting ring 23 is symmetrically provided with a slide groove 231 along the thickness direction on one side close to the mounting plate 21, an elastic telescopic rod 232 is fixed in the slide groove 231, a lifting block 233 sliding along the slide groove 231 is fixed on the top of the elastic telescopic rod 232, and a slide rail 221 is fixed along the thickness direction at the corresponding positions of the limiting plate 22 and the lifting block 233, and a slider 222 adapted to the lifting block 233 is slidably connected in the slide rail 221; the top of the lifting block 233 extends into the interior of the slide rail 221 and abuts against the bottom of the slider 222; through the cooperation of the slider 222, the lifting block 233, the elastic telescopic rod 232 and the slide rail 221, the mounting ring 23, the filter screen 24 and the limiting plate 22 can be quickly installed and disassembled.

[0026] As a possible implementation of the present solution, preferably, a handle 212 is fixed to the outer wall of the mounting plate 21 ; the filter assembly 2 can be easily rotated by the handle 212 .

[0027] As a possible implementation of the present scheme, preferably, a sealing layer 213 is fixed to the top and bottom of the mounting plate 21; by setting the sealing layer 213, it is possible to prevent some gas from being discharged from the gap between the mounting plate 21 and the guide groove 11 without being filtered, thereby avoiding pollution to the atmosphere.

[0028] The working principle of this device is:

[0029] When replacing the filter 24, the filter assembly 2 is rotated by the handle 212 until the filter 24 completely leaves the inside of the chimney 1, and then the two sliders 222 are pressed so that the lifting block 233 pushes the elastic telescopic rod 232 to slide downward until the top of the lifting block 233 is flush with the mounting ring 23. At this time, the mounting ring 23 can be taken out from between the two limit plates 22 for replacement. After the replacement is completed, the filter assembly 2 is pushed into the inside of the chimney 1 by the handle 212 to complete the installation.
