Embodiment Construction
[0030] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0031] see figure 1 , figure 2 and image 3 , the present embodiment provides a limestone multi-stage sieving device, comprising a first sieving mechanism 10, a second sieving mechanism 20, a feed hopper 30, a discharge pipe 40 and a frame 50, the first sieving mechanism and the second sieving mechanism The second screening mechanism is installed on the frame from top to bottom. The first screening mechanism includes a screening cavity 11, a blowing unit 12 and a conveying pipe 13, and the blowing unit is a Roots blower, a side flow fan or a multi-stage centrifugal blower. The second screening mechanism is configured with the same structure as the first screening mechanism. The feed hopper is installed on the top surface of the s...

The invention provides a limestone multi-stage sieving device, which comprises a first sieving mechanism, a second sieving mechanism, a feeding hopper, a discharge pipe and a machine frame. The first sieving mechanism includes a sieving cavity, a blowing unit and a conveying pipe. The limestone to be sieved is transported into the sieving cavity through the feed hopper, and the blowing unit is turned on to blow air toward the sieving cavity through the blowing pipe, so that The limestone in the sieving chamber is driven by the airflow to flow towards the direction of the conveying pipe. There is a sieve net in the sieving chamber, so the fine-grained limestone is output through the conveying pipe through the sieving, while the coarse-grained limestone is heavy due to its heavy weight. It falls into the guide tube and is transported to the second screening mechanism through the guide tube for re-screening. Then, the coarse-grained limestone is output through the discharge pipe, and the fine-grained limestone is communicated with the conveying pipe of the first sieving mechanism to be transported, and the purpose of fully sieving the limestone is achieved.
Description
technical field [0001] The invention relates to the field of limestone sieving equipment, in particular to a limestone multistage sieving equipment. Background technique [0002] Currently, dry desulfurization is one of the main processes for flue gas desulfurization. In the dry desulfurization process, the flue gas is desulfurized by adding slaked lime as an absorbent in the absorbent bin. However, the existing slaked lime will be mixed with more coarse particles of impurities. If the low-quality slaked lime is directly used, the service life of the absorption tower will be reduced, and the operation and maintenance management costs of the entire desulfurization will increase. Contents of the invention [0003] For this reason, it is necessary to provide a limestone multi-stage sieving equipment to solve the problem that the limestone is doped with coarse-grained limestone impurities. [0004] In order to achieve the above object, the inventor provides a limestone multi...
