Technical Field

[0001] The utility model belongs to the technical field of cyclones, and particularly relates to a preheater cyclone structure with low wind resistance. Background Art

[0003] Related technicians in the field found that the current cyclone is only a simple combination of an inner cylinder, a conical cylinder and an outer cylinder, and the diameter size of its inner cylinder and the length size extending into the outer cylinder cannot be changed. Therefore, the wind resistance cannot be changed according to actual needs, and then the separation efficiency and heat exchange efficiency cannot be changed. Summary of the Utility Model

[0006] A preheater cyclone structure with low wind resistance, including an outer cylinder, a rectangular cylinder is connected to the input end of the outer cylinder, the width dimension of the rectangular cylinder is the radius dimension of the outer cylinder, the side surface of the rectangular cylinder is tangent to the outer cylinder, a conical cylinder is installed below the outer cylinder, and a dust discharge port is provided at the output end of the conical cylinder;

[0007] An inner cylinder is slidably installed at the central position of the outer cylinder, the inner cylinder is connected with a bracket, the bracket is connected with an air inlet cylinder, an empty slot is formed between the inner cylinder and the air inlet cylinder, elastic ribs are installed in the empty slot, and a windproof cloth is installed outside the elastic ribs;

[0008] The outer cylinder is threadedly installed with a lead screw, and the end of the lead screw is rotatably installed on the air inlet cylinder.

[0009] Further limited, an inclined port is provided at the output port of the rectangular cylinder. With such a design, the aperture of the output end of the rectangular cylinder is enlarged, and thus the ventilation area is enlarged.

[0010] Further limited, a ratchet handle is installed at the end of the lead screw. With such a design, it is convenient to rotate the lead screw.

[0011] Further limited, a sealed rolling bearing is installed between the outer cylinder and the inner cylinder. With such a design, while ensuring the sealing effect, the movable effect of the inner cylinder is ensured.

[0012] Further defined, a guide rod is rotatably installed on the air inlet cylinder, and the guide rod is slidably installed on the outer cylinder. With such a design, the lifting of the air inlet cylinder is stable.

[0013] Beneficial effects of adopting the present utility model:

[0014] With the structural design of the present utility model, when the windproof cloth is subjected to excessive wind pressure, it will deform and then shrink inward, changing the overall diameter of the inner cylinder, expanding the gap between the outer cylinder and the inner cylinder, increasing the flow rate, and achieving the purpose of reducing wind resistance.

[0015] With the structural design of the present utility model, after impurities impact on the windproof cloth, the windproof cloth can unload the force, thereby reducing the damage and noise caused by hard impact.

[0016] With the structural design of the present utility model, rotating the screw rod can change the length dimension of the inner cylinder extending into the outer cylinder, thereby changing the suspension and heat exchange efficiency of the raw material and reducing the pressure loss.
