Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, and more specifically to a cement kiln particle separation device. Background Art

[0002] Cement kiln is an industrial device used for calcining cement clinker. Cement is obtained by adding limestone and clay into cement kiln and calcining at high temperature. Cement clinker calcination is a high-temperature thermodynamic process, which requires burning a large amount of coal powder in the kiln to provide heat. The combustion of coal powder and the clinker calcination process will produce a certain amount of pollutant emissions. If the particulate matter produced by cement clinker calcination and coal powder combustion is directly discharged into the atmosphere without treatment, it is easy to cause severe weather such as haze. Therefore, in order to solve these problems, we proposed a cement kiln particulate matter separation device to solve the problem.

[0003] The prior art patent document with publication number CN217785860U provides a cement kiln particle separation device, which filters the gas generated by calcining cement through a filter, then uses a brush to sweep the particles on the filter into a collection frame, and then takes out the collection frame to process the particles.

[0004] Although the cement kiln particulate separation device has many beneficial effects, the following problems still exist: the cement kiln particulate separation device processes the particulate matter in the collection frame by directly taking out the collection frame. When the device is running, the collection frame of the device is in an open state after the collection frame is removed. It is easy to cause gas leakage if it cannot be sealed in time. The sealing performance of the device is poor and needs to be improved. Secondly, the cement kiln particulate separation device is not easy to take out the filter screen. Therefore, the filter screen cannot be removed in time for cleaning after the device is used, and the convenience of the device needs to be improved. Therefore, a cement kiln particulate separation device is proposed to address the above problems. Utility Model Content

[0032] The sealing component 2 includes a sliding frame 210 installed on the side wall of the box body 110, the side wall of the sliding frame 210 is slidably connected to the slider 220, and the side wall of the sliding frame 210 is provided with a sliding groove 230, and the side wall of the slider 220 is installed with a baffle 240. The sliding frame 210 cooperates with the slider 220 and the sliding groove 230 to slide the baffle 240. When the storage frame 120 is removed, the opening can be quickly closed to reduce gas leakage, and the device has good sealing performance.

[0033] The filter assembly 3 includes a sliding frame 340 installed below the box cover 150, the side wall of the sliding frame 340 is slidably connected to the slider 350, and a connecting plate 360 ​​is installed below the slider 350. The sliding frame 340 cooperates with the slider 350 to slide and connect the plate 360, so that the filter assembly 3 can be taken out, which is convenient for cleaning the removed filter assembly 3 after replacing it with a new one. The device is highly convenient.
