Abstract
Description
[Technical field]
[0001] The utility model belongs to the technical field of environmental protection, and particularly relates to a cyclone water quality filter used in front of a sprayer. [Background technology]
[0002] The water filter is an essential equipment to ensure the normal use of the dust suppression sprayer in the mine. Regularly cleaning the particles and impurities on the filter net is the daily maintenance content of the water filter. The common practice of cleaning the slag of the pre-filter of the known mine dust suppression sprayer is to open the slag discharge port of the filter and drain water directly to the particles on the filter net. If the particles on the filter net are firmly attached, the filter element must be manually removed and scrubbed, which greatly wastes the workers' time and energy. [Utility Model Content]
[0003] In order to solve the above problems, the utility model proposes a cyclone water filter used in front of a dust suppression sprayer in a mine.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A swirl water filter is used for pre-water filtration of a dust suppression sprayer in a mine, comprising a water distribution plate, a guide pipe, a swirl sleeve, a filter element, a steel sleeve, and a chassis. The guide pipe is inserted at the top of the filter element, the filter element is inserted into the swirl sleeve from the top, the swirl sleeve is embedded in the steel sleeve from the top, the chassis is connected to the bottom of the steel sleeve, the water distribution plate is connected to the top of the steel sleeve, the water distribution plate is provided with a water inlet, a water outlet and a central guide port, so that pressurized water enters from the water inlet of the water distribution plate, generates a swirl through the swirl sleeve, enters the filter element, returns to the water distribution plate through the guide pipe, and flows out from the water outlet of the water distribution plate.
[0006] The water distribution plate is processed with internal and external threads, connected to the swirl sleeve through the internal threads, installed on the steel sleeve through the external threads, the central guide port is inserted into the guide pipe, connected to the filtered water of the filter element, and led out from the water outlet.
[0007] Among them, the shape of the swirl sleeve is convex on the outside and concave on the inside, with a hole in the middle. The thin end of the boss is processed with an external thread connecting to the water distribution plate, and the thick end of the boss is processed with a flow hole and a swirl groove. The middle hole is used to assemble the filter element, so that the water from the water distribution plate enters the swirl groove through the flow hole of the swirl sleeve, and the generated swirl water then enters the filter element.
[0008] Among them, the guide pipe has a shoulder in the middle, and the tubes on both sides are of different thicknesses. The thick end is inserted into the filter element, and the thin end is inserted into the central guide port of the water distribution tray. Both are sealed to guide the filtered water to the outlet of the water distribution tray through the guide hole of the guide pipe, while isolating the water flow before and after filtration.
[0009] Wherein, a positioning spring is also arranged between the bottom end of the filter element and the chassis.
[0010] Among them, a slag discharge port is provided in the center of the chassis, and the slag discharge port is used to connect the slag discharge valve. Under normal circumstances, the slag discharge port is in a closed state. When the slag needs to be cleaned, the slag discharge port is opened to allow the swirling water to be discharged through the slag discharge port after cleaning the particles on the filter element forward and reverse.
[0011] The beneficial effect of the utility model is that the cyclone water quality filter causes the water flowing through the filter to produce a cyclone through the internal cyclone sleeve, which does not affect the normal water flow, but keeps the particles on the filter screen in a state of motion at all times and will not be firmly attached to one location for a long time. In this way, when the filter screen is cleaned, the attached particles can be easily discharged by the cyclone with backwashing function, which can reduce the cost of manual maintenance of the filter element and has a simple structure.

[0018] In this embodiment, the water distribution plate 1 is processed with internal and external threads, connected to the swirl sleeve 3 through the internal threads, and installed on the steel sleeve 5 through the external threads. The central guide port e is inserted into the guide pipe 2, connected to the filtered water of the filter element 4, and led out from the outlet b.
[0019] In this embodiment, the swirl sleeve 3 is convex on the outside and concave on the inside, with a hole in the middle. The thin end of the boss is processed with an external thread connected to the water distribution plate 1, and the thick end of the boss is processed with a flow hole and a swirl groove. The middle hole is used to assemble the filter element 4, so that the water entering the water distribution plate 1 enters the swirl groove through the flow hole of the swirl sleeve 3, and the generated swirl water then enters the filter element 4.
[0020] In this embodiment, the guide tube 2 has a shoulder in the middle, and the tubes on both sides are of different thicknesses. The thick end is inserted into the filter element 4, and the thin end is inserted into the central guide port e of the water distribution tray 1. Both are sealed. The guide hole c of the guide tube 2 is used to guide the filtered water to the outlet of the water distribution tray 1, and at the same time isolate the water flow before and after filtration.
