Problems solved by technology
[0003] The inventors found that there are at least the following problems in the prior art: the centrifugal dedusting device of the existing asphalt mixing plant often has a poor effect of recovering large particles, and the universal compatibility is poor. When the production capacity of the mixing plant changes, The centrifugal dust removal device cannot be effectively matched or adjusted adaptively, which affects the first-level dust removal effect and the utilization rate of recovered coarse powder, which in turn affects the dust emission of the mixing station and causes air pollution in the surrounding environment

Embodiment Construction
[0047] Combine below Figure 1 to Figure 4 The technical solution provided by the present invention is described in more detail.
[0048] see figure 1 , the embodiment of the present invention provides a centrifugal dust removal device, including a cavity 1 and a guide assembly 2, the cavity 1 has an inlet 11, a chamber 12 and an outlet 13, see figure 2 . The flow guide assembly 2 is arranged in the chamber 12, and the flow guide assembly 2 and the inner wall of the cavity 1 jointly form a fluid circulation channel; the fluid flowing in through the inlet 11 is centrifugally removed in the fluid flow channel and then flows out through the outlet 13; wherein, At least some regions of the fluid communication channel can vary in size so that the fluid communication channel allows a variable flow rate of fluid therethrough.
[0049] The fluid flows into the chamber 1 through the inlet 11 , then enters the fluid communication channel regions M1 and M2 , and then flows out throug...

Abstract
The invention discloses a centrifugal dust removal device, a dust removal system and a mixing plant and relates to the field of road building machines. The centrifugal dust removal device, the dust removal system and the mixing plant are used for achieving adjustment of the dust removal capacity of the centrifugal dust removal device. The centrifugal dust removal device comprises a cavity and a flow guide assembly. The cavity is provided with an inflow opening, a chamber and an outflow opening, the flow guide assembly is arranged in the chamber, and a fluid circulation channel is formed by the flow guide assembly and the inner wall of the cavity together; and after fluid flowing in through the inflow opening is subjected to centrifugal dust removal in the fluid circulation channel, the fluid flows out through the outflow opening, wherein the size of at least part of the region of the fluid circulation channel can be changed, so that the flow of the fluid allowed to pass through the fluid circulation channel is changed. By the adoption of the centrifugal dust removal device provided by the above technical scheme, the size of part of the region of the fluid circulation channel can be changed, so that the flow of the fluid flowing through the region is changed, and therefore the dust removal capacity of the centrifugal dust removal device is changed.
Description
technical field [0001] The invention relates to the field of road construction machinery, in particular to a centrifugal dust removal device, a dust removal system and a mixing station. Background technique [0002] With the establishment of a large number of infrastructure construction projects and the renovation of old roads, the demand for asphalt mixture is increasing. Based on the needs of energy saving, emission reduction and environmental protection, the industry has higher and higher requirements for the technical performance indicators of asphalt mixing equipment. Centrifugal dust removal device is used as the primary dust removal device of the mixing plant, and its dust removal performance will have a great impact on the next-level dust removal system. [0003] The inventors found that there are at least the following problems in the prior art: the centrifugal dedusting device of the existing asphalt mixing plant often has a poor effect of recovering large particle...
