Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone dust removal technology, specifically to a cyclone dust collector with enhanced cyclone blades. Background Technology
[0002] In industrial production, the treatment of dust-laden gas is crucial, and cyclone dust collectors, as a common gas-solid separation device, are widely used in various fields. Traditional cyclone dust collectors typically consist of a cyclone dust collector cylinder, an inlet duct, an exhaust stack, and a dust collection cylinder. Dust-laden gas enters the cyclone dust collector cylinder through the inlet duct and rotates within the cylinder, generating centrifugal force to achieve gas-solid separation. However, traditional cyclone dust collectors have some shortcomings in practical applications. On the one hand, the limited velocity of the dust-laden gas entering the inlet duct results in insufficient swirling intensity and centrifugal force within the cyclone dust collector cylinder, making it difficult to effectively separate some fine particles from the gas, thus limiting dust removal efficiency. On the other hand, if additional fresh air is introduced to enhance airflow dynamics, the fresh air may carry external dust, which undoubtedly increases the burden on the cyclone dust collector, further reducing the dust removal effect. Furthermore, the introduction of fresh air may increase energy consumption and costs. Therefore, we propose a cyclone dust collector with enhanced cyclone vanes. Utility Model Content
[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a cyclone dust collector with enhanced cyclone blades, which can solve the above problems.
[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0005] A cyclone dust collector with enhanced cyclone blades includes a cyclone dust collector cylinder, an air inlet duct, an exhaust stack, a support frame, a dust collection cylinder, and a dust-laden gas conveying fan. The air inlet end of the air inlet duct is connected to a dual-channel pipe. One air inlet end of the dual-channel pipe is connected to the exhaust end of the fan through duct A, and the air inlet end of the fan is connected to one side of the top of the exhaust stack through duct B. The other air inlet end of the dual-channel pipe is connected to the exhaust end of the dust-laden gas conveying fan through duct C.
[0006] Furthermore, a spiral guide plate is welded and fixed to the top of the inner wall of the cyclone dust collector. The initial end of the spiral guide plate is seamlessly connected to the top of the air inlet duct and the air outlet. One side of the air inlet duct and the air outlet are tangent to the top of the inner wall of the cyclone dust collector, and a side guide plate is welded and fixed to the other side of the air inlet duct and the spiral guide plate is welded and fixedly connected.
[0007] Furthermore, a partition is fixedly installed inside the dual-channel pipe, and valve plates are hinged to the top surface of the inner wall of the dual-channel pipe and the bottom surface of the partition. A baffle is fixedly installed on the top surface of the partition and the bottom surface of the inner wall of the dual-channel pipe.
[0008] Furthermore, the valve plate has a cavity inside for weight reduction, and the baffle has an inclined surface on the side facing the valve plate. When the valve plate and the baffle are in contact, the valve plate has an inclination angle of 45° to 60°.
[0009] Furthermore, a conical baffle is fixed to the top of the exhaust pipe by a support rod.
[0010] Furthermore, the dust-laden gas conveying fan is fixedly installed on the surface of the raised platform, and an L-shaped baffle is fixedly installed on one side of the raised platform.
[0011] The beneficial effects of this utility model are as follows: The device of this application is equipped with a double-channel pipe. With the help of the fan, fresh air is introduced into the double-channel pipe, which can accelerate the entry of dust-containing airflow into the air inlet duct. The dust-containing airflow is guided by the spiral guide plate and generates a downward swirling flow in the cyclone dust collector. Centrifugal force separates the gas and solid. The purified airflow is discharged from the exhaust pipe, and the dust is accumulated in the dust collection cylinder.
[0012] The fresh air from the fan is discharged through the exhaust pipe after the dust has been purified, thus avoiding the fresh air carrying dust and increasing the dust removal pressure of the cyclone dust collector. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0021] like Figure 1-3 As shown, this utility model discloses a cyclone dust collector with enhanced cyclone blades, including a cyclone dust collector 1, an air inlet duct 6, an exhaust stack 2, a support 7, a dust collection cylinder 8, and a dust-laden gas conveying fan 5. The air inlet end of the air inlet duct 6 is connected to a double-channel pipe 4. One air inlet end of the double-channel pipe 4 is connected to the exhaust end of the fan 3 through a duct A301. The air inlet end of the fan 3 is connected to one side of the top of the exhaust stack 2 through a duct B302. The other air inlet end of the double-channel pipe 4 is connected to the exhaust end of the dust-laden gas conveying fan 5 through a duct C501.
[0022] Example 1: The dust-laden gas conveying fan 5 is connected to the lower channel of the double-channel pipe 4 through the duct C501, and the fan 3 is connected to the upper channel of the double-channel pipe 4 through the duct A301. The fan 3 reintroduces the purified airflow from the exhaust stack 2 into the double-channel pipe 4, which then passes through the air inlet duct 6 and the spiral guide plate 9 and enters the cyclone dust collector 1 to generate a swirling flow. The dust-laden gas conveying fan 5 introduces the dust-laden airflow into the lower channel of the double-channel pipe 4 through the duct C501. The airflow in the upper channel of the double-channel pipe 4 can carry the dust-laden airflow into the air inlet duct 6, which can increase the speed of the dust-laden airflow. The dust-laden airflow is guided by the spiral guide plate 9 to generate a downward swirling flow in the cyclone dust collector 1. Centrifugal force separates the gas and solid. The purified airflow is discharged from the exhaust stack 2, and the dust is accumulated in the dust collection cylinder 8. Part of the purified airflow is discharged from the top of the exhaust stack 2, and part of it is used as fresh air for the fan 3.
[0023] In the preferred technical solution, a spiral guide plate 9 is welded and fixed to the top of the inner wall of the cyclone dust collector 1. The initial end of the spiral guide plate 9 is seamlessly connected to the top of the exhaust end of the air inlet duct 6. One side of the exhaust end of the air inlet duct 6 is tangent to the top of the inner wall of the cyclone dust collector 1, and a side guide plate 10 is welded and fixed to the other side of the exhaust end of the air inlet duct 6. The side guide plate 10 is welded and fixedly connected to the spiral guide plate 9. The spiral guide plate is seamlessly welded to the air inlet duct and the side guide plate, so that the dust-laden airflow rotates downward along the spiral trajectory, which enhances the centrifugal dust removal effect. The side guide plate can guide the gas to be evenly distributed. The two work together to improve the gas-solid separation efficiency and reduce the equipment pressure drop and wear risk.
[0024] In the preferred technical solution, a baffle 401 is fixedly installed inside the dual-channel pipe 4. A valve plate 11 is hinged to the top surface of the inner wall of the dual-channel pipe 4 and the bottom surface of the baffle 401. A baffle 12 is fixedly installed to the top surface of the baffle 401 and the bottom surface of the inner wall of the dual-channel pipe 4. The baffle and the hinged valve plate inside the dual-channel pipe, together with the baffle, form a unidirectional flow structure: when the airflow flows in the forward direction, the valve plate is opened by pressure to realize dual-channel flow; when the airflow flows in the reverse direction, the valve plate and the baffle are fitted together to close the channel, effectively preventing gas backflow and improving the system's sealing performance and operational stability.
[0025] In the preferred technical solution, the valve plate 11 has a cavity inside for weight reduction, and the baffle 12 has an inclined surface on the side facing the valve plate 11. When the valve plate 11 and the baffle 12 are in contact, the valve plate 11 is at an angle of 45° to 60°. The cavity in the valve plate reduces weight, lowers opening and closing resistance, and improves response speed. The inclined surface of the baffle and the inclination of the valve plate cooperate to form a guiding sealing structure, making the fit tighter, enhancing the anti-backflow effect, reducing impact wear, extending the service life of the valve plate and the baffle, and ensuring stable operation of the system.
[0026] In the preferred technical solution, a conical baffle 201 is fixedly installed on the top of the exhaust pipe 2 by a support rod. The conical baffle on the top of the exhaust pipe can effectively prevent rainwater and debris from falling into the pipe, avoiding equipment corrosion or blockage. Its conical structure is conducive to guiding the airflow to diffuse smoothly, reducing exhaust resistance and noise. At the same time, the support rod fixing method is stable and reliable, reducing baffle vibration and ensuring long-term stable operation of the exhaust system.
[0027] In the preferred technical solution, the dust-laden gas conveying fan 5 is fixedly installed on the surface of the raised platform, and an L-shaped baffle is fixedly installed on one side of the raised platform. The L-shaped baffle can protect the dust-laden gas conveying fan 5 from rain.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
