Description

Technical Field

[0001] This utility model belongs to the field of cyclone separator technology, and specifically relates to a dual cyclone separator. Background Technology

[0002] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. Its working principle relies on the rotational motion caused by the tangential introduction of airflow, which throws solid particles or liquid droplets with significant inertial centrifugal force against the outer wall surface, separating them. Dual cyclone separators can achieve secondary separation, resulting in superior separation performance. However, most dual cyclone separators currently on the market are composed of two individual units connected in parallel, leading to a relatively large size and hindering the miniaturization and portability of cyclone separators. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a dual cyclone separator that cleverly combines two cyclone mechanisms, thereby reducing the size of the entire device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual cyclone separator includes a first cyclone separation mechanism and a second cyclone separation mechanism. The first cyclone separation mechanism includes a first cyclone generating component disposed on a collection tank. The first cyclone generating component is provided with a first air inlet and a first air outlet.

[0006] The second cyclone separation mechanism includes a second cyclone generating component and a second separation barrel. The second cyclone generating component is disposed on the second separation barrel, and the second cyclone generating component is provided with a second air inlet and a second air outlet.

[0007] The first air outlet is located at the center of the bottom of the first cyclone generator, and the first air outlet is connected to the second air inlet;

[0008] The second separation barrel is mounted on the first cyclone generator and its bottom extends below the first cyclone generator. The bottom of the second separation barrel has a discharge port with an openable cover.

[0014] To better realize this utility model, the above structure is further optimized by setting the second air outlet at the top center of the second cyclone generator component.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The dual cyclone separator provided by this utility model connects the first cyclone separation mechanism and the second cyclone separation mechanism together, and hides part of the connecting pipeline of the two separation mechanisms inside the device, reducing the overall volume and reducing power loss in the transmission pipeline, thus improving working efficiency.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1-4 The dual cyclone separator provided by this utility model includes a first cyclone separation mechanism and a second cyclone separation mechanism. The first cyclone separation mechanism includes a first cyclone generating component 1 disposed on a collection bucket (the collection bucket is prior art and is not shown in the accompanying drawings to highlight the key differences between this application and the prior art). The first cyclone generating component 1 is provided with a first air inlet 101 and a first air outlet 102. The first air inlet 101 is located on the side of the first cyclone generating component 2. The first air outlet 102 is located at the bottom center of the first cyclone generating component 1. A guide pipe 5 is vertically disposed at the bottom center of the first cyclone generating component 1, and the first air outlet 102 is disposed inside the guide pipe 5, which guides the airflow direction so that the airflow moving upward in the center of the collection bucket can smoothly and quickly reach the first air outlet 102. The airflow enters from the first air inlet 101, spirally separates dust in the collection bucket, and finally moves upward from the bottom center and is discharged from the first air outlet 102.

[0028] The second cyclone separator includes a second cyclone generating component 2 and a second separating tank 3. The second cyclone generating component 2 is mounted on the second separating tank 3, and has a second air inlet 201 and a second air outlet 202. The second air inlet 201 is located on the side of the second cyclone generating component 2. The second air outlet 202 is located at the top center of the second cyclone generating component 2. Similar to the working principle of the first cyclone separator, airflow enters through the second air inlet 201, undergoes gas-solid separation, and then exits through the second air outlet 202.

[0029] The first air outlet 102 is connected to the second air inlet 201 through the guide pipe 6, thereby realizing the docking of the first cyclone separator and the second cyclone separator. The airflow separated by the first cyclone separator enters the second cyclone separator through the guide pipe 6 for secondary separation, separating small dust particles in the airflow and improving the separation effect.

[0030] This application is mainly used in conjunction with a vacuum cleaner to perform secondary separation of dust. The first cyclone separation mechanism is used to separate large dust particles, and the second cyclone separation mechanism is used to separate small dust particles, which improves the dust separation effect. Moreover, compared with the parallel structure in the prior art, this application has a smaller volume and higher separation efficiency, and has a wider range of application prospects.

[0031] Since dust also accumulates inside the second separation tank 3, the device requires a special design; see details below. Figure 2 The second separating bucket 3 is mounted on the first cyclone generator 1 and its bottom extends below the first cyclone generator 1. A discharge port 301 is located at the bottom of the second separating bucket 3, and an openable cover 4 is provided at the discharge port 301. Dust is cleaned by opening and closing the cover 4. During operation, the cover 4 must be closed, allowing small dust particles inside the second separating bucket 3 to accumulate at the bottom. When operation stops, the cover 4 must be opened, allowing the small dust particles inside to fall into the collection bucket below. To improve automation, in this embodiment, the opening end face of the discharge port 301 is inclined downwards, and the cover 4 is hinged to the top of the discharge port 301. Gravity is used to automatically open the cover 4, and suction is used to automatically close the cover 4.

[0032] The working principle is as follows:

[0033] In use, the first cyclone generator 1 of this device needs to be covered on the collection bucket. Then, under the suction of the vacuum cleaner, the airflow carrying dust enters from the first air inlet 101 for primary separation, separating large dust particles from the airflow, which fall and accumulate at the bottom of the collection bucket. Then, the separated airflow moves upward from the bottom center to the first air outlet 102, and then enters the second air inlet 201 through the guide pipe 6 to begin secondary separation, separating small dust particles from the airflow. At the same time, under the action of suction, the cover 4 at the bottom of the second separation bucket 3 automatically closes, and the small dust particles separated in the second separation bucket 3 fall and accumulate at the bottom of the bucket. Finally, the separated airflow is discharged from the second air outlet 202, completing the separation. At this time, there is no suction, the cover 4 automatically opens, and the small dust particles accumulated at the bottom of the second separation bucket 3 fall into the collection bucket below for centralized processing.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
