Description

Technical Field

[0001] The invention relates to the technical field of compressed air source processing, in particular to a cyclone high efficiency filter. Background Art

[0002] A filter is a device used to separate, remove or screen substances. It plays a key role in many fields. In terms of working principle, it mainly separates substances through physical, chemical or biological methods. For example, physical filtration uses the pores of materials such as filter screens and filter elements to block particles larger than the pore size from passing through, just like our common sieves, which only allow substances smaller than the sieve size to pass through. In air filtration, fiber filters can intercept dust particles; in water filtration, sand filters intercept impurities suspended in water through sand layers of different particle sizes. In terms of structure, there are many types of filters. A simple filter may consist of only a filter medium (such as filter paper) and a shell, like a funnel-type filter paper filter used to filter solutions in the laboratory. The solution is poured from the top of the filter paper, the solid remains on the filter paper, and the liquid flows through the filter paper into the container below. Complex filters may contain multiple layers of filter media, as well as special water inlets and outlets, sewage outlets, and even backwashing devices. For example, large industrial water filters have a complex internal structure in order to cope with the continuous filtration of large amounts of water and ensure the filtration effect and equipment life.

[0003] At present, most compressed air filters at home and abroad use filter elements as filter materials. Filter elements are usually composed of multiple layers of materials with different densities to effectively filter impurities such as solid particles, oil mist, and water vapor in the air.

[0004] However, in actual application, we found that there is a significant problem with the filter element, that is, it is easy to get clogged, which leads to increased internal pressure. This phenomenon will directly shorten the service life of the filter and make the filtration efficiency unsatisfactory. The high-efficiency filters on the market currently lack the ability to adjust the ventilation efficiency, which makes them unable to flexibly adapt to various different usage environments, but the filters using filter elements need to frequently clean or replace their internal filter elements, which undoubtedly increases the inconvenience of users. In view of this, we proposed a new type of cyclone high-efficiency filter. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cyclone high efficiency filter, which solves the problem that the filter element in the prior art is easily clogged and has high back pressure, resulting in a shortened filter service life and low filtration efficiency.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cyclone high efficiency filter, comprising a valve body, the upper part of the valve body is sleeved with a labyrinth core, the lower part of the labyrinth core is threadedly connected with a labyrinth shaft, the lower part of the valve body is sleeved with a connecting sleeve, the lower part of the connecting sleeve is fixedly connected with a gasket, the lower part of the connecting sleeve is fixedly connected with an O-ring four, the lower part of the connecting sleeve is sleeved with a cup, the interior of the cup is fixedly connected with an automatic drain valve, and the lower part of the automatic drain valve is fixedly connected with an automatic drain valve connector.

[0007] Preferably, the lower part of the valve body is provided with multiple groups of arc-shaped grooves, and the grooves in the lower part of the valve body are respectively located on the outer side, the middle part and the inner side thereof. The lower part of the valve body is fixedly connected with O-type sleeve 1, the lower part of the valve body is fixedly connected with O-type sleeve 2, and the lower part of the valve body is fixedly connected with O-type sleeve 3. The three groups of O-type sleeves arranged here are made of the same material, and the sealing between the valve body and the lower connecting sleeve and the labyrinth core is ensured by the arranged O-type sleeve 1, O-type sleeve 2 and O-type sleeve 3.

[0008] Preferably, a through thread groove is provided at the lower portion of the labyrinth core, and a mounting mechanism is provided at the lower portion of the labyrinth core.

[0009] Preferably, the mounting mechanism comprises a hexagon socket screw, the threaded surface of the hexagon socket screw is threadedly connected to the mounting bracket, and the inner surface of the mounting bracket is provided with a threaded through hole.

[0010] Preferably, a flat washer is provided between the hexagon socket screw and the mounting frame, and two groups of mounting mechanisms are provided, and the two groups are symmetrically distributed with the center line of the connecting sleeve as the symmetry axis. Therefore, the device is fixed by the mounting mechanisms on both sides to maintain its stability during filtering. At the same time, the high-efficiency filter is designed with an installation bracket, which can be installed according to user requirements. The overall structure is simple and flexible, and can be easily applied in a variety of scenarios.

[0011] Preferably, a through hole is provided at the bottom of the cup, and the inner diameter of the through hole at the bottom of the cup is the same as the outer diameter of the automatic drain valve joint.

[0012] Preferably, the cup and the connecting sleeve have the same outer diameter, and the connection between the two is connected to each other through an insert slot.

[0013] Preferably, a through hole is provided at the upper portion of the labyrinth core, a threaded protrusion is provided at the lower portion of the labyrinth core, and a threaded groove is provided at the upper portion of the labyrinth shaft.

[0014] Preferably, the valve body, the labyrinth core and the labyrinth shaft are all porous structures.

[0015] Preferably, a plurality of holes with different angles are provided in the inner cavity formed by the labyrinth core and the labyrinth axis.

[0016] Working principle: After the compressed air enters the new structure high efficiency filter, it first starts the first swirl in the labyrinth core, because the labyrinth core is provided with several holes at different angles arranged in a specific direction. Then the airflow enters the labyrinth axis, and the labyrinth holes at different angles on the labyrinth axis cause the compressed air to swirl for the second and third time. Finally, the compressed air is in the cup, and the swirl teeth on the cup are used to realize the fourth swirl. In this series of swirl processes, due to the high-speed rotation of the compressed air, the centrifugal effect is used to efficiently separate the moisture and particles in the compressed air. The separated moisture is at the bottom of the cup and is automatically discharged through the automatic drain valve installed in the cup, realizing the maintenance-free function.

[0017] The present invention provides a cyclone high efficiency filter having the following beneficial effects: 1. The present invention adopts a filter-free design, which avoids the problems of short filter service life and low filtration efficiency caused by easy clogging of the filter element and high back pressure. Through the unique internal maze centrifugal structure design, multiple swirls are achieved, which has a significant effect on separating moisture and particles in compressed air. The water filtration efficiency reaches 99.9%, and the oil filtration efficiency reaches more than 97%. There is no need to frequently replace the filter components, which reduces the cost of use.

[0018] 2. In the present invention, the valve body is connected to the connecting sleeve and the cup by threads and sealed by an O-ring. The valve body is also connected to the labyrinth core and the labyrinth shaft by threads. This connection method ensures reliable connection and convenient disassembly, and is convenient for installation, use and maintenance. At the same time, the high-efficiency filter is designed with an installation bracket, which can be installed according to user requirements. The overall structure is simple and flexible, and is easy to use in a variety of scenarios.

[0019] 3. The device in the present invention does not need to be plugged in, and relies on the flow of compressed air in the maze structure to achieve filtration and separation. It does not require additional power drive, saving energy consumption. Although its ventilation efficiency cannot be adjusted, the internal maze centrifugal structure can enable the compressed air to perform relatively stable and efficient cyclone separation under different working conditions. It can adapt to a variety of complex compressed air source processing environments, ensure stable operation under different working conditions, and improve the reliability and adaptability of the overall air source processing system.
