Description

Technical Field

[0001] The utility model relates to a dust collector, in particular to a cyclone dust collector with adjustable inlet and outlet. Background Art

[0002] The dust removal mechanism of the cyclone dust collector is to make the dust-laden airflow rotate, separate the dust particles from the airflow and capture them on the wall of the device with the help of centrifugal force, and then use gravity to make the dust particles fall into the ash hopper. The cyclone dust collector is composed of an air inlet pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. It is suitable for the removal of non-sticky and non-fibrous dust, and is mostly used to remove particles larger than 5μm. The various components of the cyclone dust collector have a certain size ratio. Every change in the proportional relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the inlet and outlet dimensions, and the exhaust pipe diameter are the main influencing factors. The inlet and outlet wind speeds of existing cyclone dust collectors are not easy to adjust, and the precise separation of dust particles of different particle sizes is difficult to accurately control, which affects the dust removal effect. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cyclone dust collector with adjustable inlet and outlet, and to more accurately control the separation of dust particles of different particle sizes by adjusting the sizes of the inlet and outlet.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cyclone dust collector with adjustable inlet and outlet, including a cylindrical body, a cone connected to the bottom of the cylindrical body, an air inlet arranged on one side of the cylindrical body and an air outlet arranged above the cylindrical body, and a conical pipe mouth arranged at the lower end of the cone, a wind plate is arranged at the air inlet, the angle of the wind plate can be adjusted to thereby change the wind speed at the air inlet, and a throat is arranged at the air outlet, and the telescopic distance of the throat into the cylindrical body can be adjusted to thereby change the wind speed at the air outlet.

[0005] An arc-shaped positioning plate is arranged on the cylinder at the air inlet, and an air plate adjustment handle is connected to one end of the air plate and is hinged on the cylinder, and a positioning knob on the air plate adjustment handle is passed through the arc-shaped positioning plate, and the position of the air plate adjustment handle can be fixed by the positioning knob to achieve the adjustment of the air plate angle.

[0006] A throat arc-shaped positioning plate is provided on the cylinder at the air outlet, the upper end of the throat is connected to a throat adjustment handle, one end of the throat adjustment handle is hinged on the cylinder, and a throat positioning knob on the throat adjustment handle is passed through the throat arc-shaped positioning plate. The throat positioning knob can be used to fix the position of the throat adjustment handle to achieve adjustment of the telescopic distance of the throat into the cylinder.

[0007] The utility model adopts the above technical solution to design a cyclone dust collector with adjustable inlet and outlet. Through two sets of adjustment handles, the adjustment handles are fixed at different positions of the corresponding arc positioning plate, so as to adjust the wind plate angle and the throat distance firmly, and ensure the state after adjustment under different working conditions. The utility model has the functions of adjusting the wind speed of the air inlet and the outlet air duct (adjustment throat), realizing the two-position adjustment of centrifugal force, and is an experimental cartridge dust collector.

DETAILED DESCRIPTION

[0012] The following is a detailed description of a cyclone dust collector with adjustable inlet and outlet according to the utility model in conjunction with the accompanying drawings.

[0013] The utility model is a cyclone dust collector with adjustable inlet and outlet, see Figures 1 to 3 , comprising a cylinder 2, a cone 3 connected to the bottom of the cylinder 2, an air inlet 1 arranged on one side of the cylinder 2, an air outlet arranged above the cylinder 2, and a cone pipe mouth 10 arranged at the lower end of the cone 3. A wind plate 4 is arranged at the air inlet 1, and an arc-shaped positioning plate 6 is arranged on the cylinder 2 at the air inlet 1. One end of the wind plate 4 is connected to a wind plate adjustment handle 5 and is hinged on the cylinder 2. The positioning knob (such as a bolt, etc., not shown in the figure) on the wind plate adjustment handle 5 is passed through the arc-shaped positioning plate 6. The wind plate adjustment handle 5 can be fixed by the positioning knob, thereby changing the angle of the wind plate 4 (d2 is the adjustable range of the wind plate angle), realizing the adjustment of the wind plate angle, and thus changing the wind speed of the air inlet. A throat 7 is provided at the air outlet, and a throat arc-shaped positioning plate 8 is provided on the cylinder 2 at the air outlet. The upper end of the throat 8 is connected to a throat adjustment handle 9, and one end of the throat adjustment handle 9 is hinged on the cylinder 2. A throat positioning knob (such as a bolt, etc., not shown in the figure) on the throat adjustment handle 9 is passed through the throat arc-shaped positioning plate 8. The throat positioning knob can fix the position of the throat adjustment handle 9 to achieve adjustment of the extension and retraction distance of the throat into the cylinder 2 (d1 is the adjustable range of the throat), thereby changing the wind speed at the air outlet.

[0014] In the utility model, when the gas (dry medium) containing dust enters the cyclone dust collector from the air inlet 1, the wind plate adjustment handle 5 drives the wind plate 4 to adjust the air inlet speed, thereby changing the dust particles under the action of adjustable (different) centrifugal force, and separating the dust particles that do not meet the specification particle size and discharging them from the lower cone pipe mouth 10. The upper air outlet of the cylinder 2 drives the internal adjustable throat 8 through the throat adjustment handle 9 on the side to adjust the telescopic distance of the throat 8 to the lower part, thereby changing the wind speed entering the air outlet, and also changing the dust particles under different centrifugal forces to separate dust particles of different particle sizes, and cooperates with the angle adjustment of the air inlet 1 to achieve a wider adjustment range and more accurate control of the precise separation of dust particles of different particle sizes.
