Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more specifically to a high-efficiency vortex flow filter. Background Art

[0002] Fluids (oil, water, etc.) used in industrial cleaning, degreasing and machining processes are recycled. The recycled oil contains particulate matter generated during the production process, as well as other industrial and environmental waste liquid treatment systems, which all need to filter out the particulate matter. These particulate matter components are very complex, some are mainly metal particles, some are mainly non-metal particles, or a mixture of metal and non-metal particles.

[0003] The commonly used filtering methods in the industry are mechanical filter filtration or magnetic filter. The characteristic of the mechanical filter is that the mesh size of the filter needs to be designed according to the size of the particles, and often multiple layers of filters with different mesh sizes are required; magnetic filters are suitable for filtering metal particles that can be magnetized, but have almost no effect on filtering metal and non-metal particles that cannot be magnetized. It is obviously necessary to provide a high-efficiency filter with wide applicability.

[0004] The patent with publication number CN111204891A provides a centrifugal vortex ballast water filtration device, which is composed of a cascaded two-stage conical vertical filter cartridge. The inner surface of the conical vertical filter cartridge is provided with an internal spiral thread, and a water pump is provided at the front end of the inlet of the first-stage conical vertical filter cartridge. The sewage outlet of the two-stage conical vertical filter cartridge is connected to a sewage pipeline, a sewage valve, and a sewage suction pump and a sewage collector arranged on the sewage pipeline. The design adopts physical centrifugation, which can effectively separate large particles of impurities, and the overall structure is relatively complex, requires more components, and has a high production cost.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] Example

[0030] Combination Figure 1As shown, a high-efficiency vortex flow filter of this embodiment includes a vortex chamber 2, and a nozzle 1 for raw liquid to enter is provided on the outer wall of the vortex chamber 2 along the tangential direction. The bottom of the vortex chamber 2 is connected to a collecting chamber 4, and a reflux chamber 6 is provided in the collecting chamber 4. The reflux chamber 6 is connected to the inner cavity of the collecting chamber 4, and the reflux chamber 6 extends upward from the bottom of the collecting chamber 4. A reflux pipe 7 is provided on the reflux chamber 6 and connected to a discharge pipe 8 at the top of the vortex chamber 2; an emptying port is provided at the bottom of the collecting chamber 4. The raw liquid enters in the tangential direction to generate a vortex so as to separate the solid particles from the liquid. The solid particles are concentrated in the collecting chamber 4 and can be discharged in a centralized manner, while the liquid can flow back to the outside of the vortex chamber 2 through the reflux chamber 6.

[0031] In practice, the cyclone bin 2, the collection bin 4 and the reflux bin 6 can all adopt a cylindrical structure with the same size of opening downward in the height direction. More preferably, in order to improve the separation effect, the bottom of the cyclone bin 2 has a tapered cyclone throat 3 with a gradually narrowing opening downward in the height direction, the top opening of the cyclone throat 3 is smaller than the inner cavity width of the cyclone bin 2, the collection bin 4 is located below the cyclone throat 3 and is connected to the inner cavity of the cyclone bin 2, and the inner cavity width of the collection bin 4 is significantly larger than the bottom opening of the cyclone throat 3. A better design is that there is also a tapered cavity 5 between the cyclone throat 3 and the collection bin 4, the top opening of the tapered cavity 5 is consistent with the bottom opening of the cyclone throat 3, and the opening of the tapered cavity 5 gradually expands downward in the height direction, and the inner cavity width of the collection bin 4 is larger than the bottom opening width of the tapered cavity 5.

[0032] When the above design is used, the raw liquid with a certain flow rate is input from the nozzle 1 at the upper part of the cyclone chamber 2 and in the tangential direction into the closed cyclone chamber 2. The liquid forms a cyclone along the inner wall of the cylinder and moves toward the lower part of the cylinder. The conical design of the cyclone throat 3 increases the speed of the vortex. Due to the action of centrifugal force, the solid particles in the liquid will be thrown to the cylinder wall, and the particles collected on the cylinder wall will flow through the cyclone throat 3 at the bottom of the cyclone chamber 2 to the collection chamber 4 at the bottom. The lower part of the cyclone throat 3 is a conical cavity 5. The function of the collection chamber 4 is to reduce the flow rate of the liquid so that the solid particles can settle. The conical cavity 5 can guide the vortex liquid flowing out of the cyclone throat 3. Since the circumferential side wall of the reflux chamber 6 is provided with a connecting channel to maintain communication with the collection chamber 4, the clean liquid separated in the collection chamber 4 will enter the reflux chamber 6 under the action of the vortex pressure and gradually move upward, and then be transported back to the middle part of the upper cyclone chamber 2 through the reflux pipe 7, and then flow out through the discharge pipe 8 at the top. In order to prevent the filtered particles from entering the reflux bin 6 along with the liquid, a filter is provided on the communication channel of the circumferential side wall of the reflux bin 6 to prevent the solid particles from entering and achieve efficient separation.

[0033] In order to optimize the spatial layout of each component, in this embodiment, the reflux bin 6 is arranged at the center of the collecting bin 4, and the reflux bin 6, the reflux pipe 7 and the discharge pipe 8 are coaxially arranged and coaxial with the axis of the swirl throat 3. In order to facilitate the connection and coordination of each component, the discharge pipe 8 is located at the top center of the swirl bin 2 and is detachably mounted with the swirl bin 2; the reflux bin 6 is arranged at the center of the collecting bin 4 and is detachably mounted with the bottom of the collecting bin 4; the reflux pipe 7 is arranged at the top center of the reflux bin 6 and is detachably mounted with the reflux bin 6, and can be specifically installed in the form of threaded mounting. And the emptying port at the bottom of the collecting bin 4 is provided with an emptying flange 9 and an emptying valve 10, which are used to control the uniform discharge of the separated particles.

[0034] In this embodiment, the design of the reflux bin 6 and the reflux pipe 7 can not only prevent the liquid in the collection bin 4 from flowing back into the vortex bin 2 through the vortex throat 3 at the bottom of the vortex bin 2 to destroy the vortex in the vortex bin 2, but also provide a channel for the clean liquid to be discharged after separation, thereby realizing the independent filtration separation, clean water reflux and particle discharge. In addition, the overall structure is compact, simple, and low in cost, and is very suitable for promotion and application.

[0035] The above is a schematic description of the present invention and its implementation methods, which is not restrictive and is only one of the implementation methods of the present invention, and is not actually limited to this. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
