Description

Technical Field

[0001] This utility model relates to the field of centrifugal filter technology, specifically to a multi-chamber centrifugal filter. Background Technology

[0002] Currently, there is a centrifugal filter on the market that is driven by water flow to rotate, which does not require additional electricity and is easy to use.

[0003] For example, among numerous existing technologies, Chinese patent application CN102120198B discloses a flushing centrifugal filter, which includes a base fixedly connected to front and rear supports and a housing. The front and rear supports are rotatably connected to a rotating shaft and a circular screen. The hollow rotating shaft is divided into two sections. The first section is connected to a feed pipe, and a feed nozzle is mounted on this section of the shaft. The second section is connected to a cleaning pump, and an internal cleaning nozzle is mounted on this section of the shaft. This invention injects pressurized suspension into the inner wall of the circular screen through the feed nozzle, providing both filtration pressure and flushing the screen. The rapidly rotating circular screen provides continuous centrifugal force to the wastewater or filtrate. Movable centrifugal scrapers, closely attached to the inner wall of the screen, obliquely scrape the solid material, automatically and continuously pushing it forward, thus achieving solid-liquid separation. The internal and external cleaning nozzles can perform manual or automatic cleaning of the circular screen during normal operation.

[0004] However, the rinsing water in this patent application mixes with the filtered water, making it impossible to separate the two levels of clean water for discharge.

[0005] Based on this, the present invention designs a multi-chamber centrifugal filter to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] The terms "left," "right," "front," "back," "up," and "down" used in the following description are oriented from the perspective of a top-down view.

[0039] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A multi-chamber centrifugal filter includes a filter body 1, which includes a housing 11, a first partition 12, a second partition 13, a first liquid outlet 14, a second liquid outlet 15, a third liquid outlet 16, an inlet pipe 17, and a high-pressure nozzle 18.

[0040] Partition 12 and partition 23 are fixedly installed in the inner end of the box 11 from left to right. The inner end of the box 11 is provided with a first cavity located at the left end of partition 12, a second cavity located between partition 12 and partition 23, and a third cavity located at the right end of partition 23, from left to right.

[0041] Both liquid outlet 14 and liquid outlet 2 15 are fixedly installed on the lower side of the front end face of the housing 11, and liquid outlet 14 and liquid outlet 2 15 are respectively connected to the first cavity and the second cavity;

[0042] There are two liquid outlets 16, which are fixedly installed on the lower side of the front and rear end faces of the housing 11, and the liquid outlets 16 are connected to the third cavity.

[0046] It also includes a cleaning component 3, which is connected to the rotating water injection filter component 2. The cleaning component 3 is used to clean the bottom of the second chamber.

[0047] In use, this invention divides the inner end of the housing 11 into three independent chambers, thus preventing the liquids in the three chambers from mixing. The rotating drive end of the rotating water injection filter assembly 2 in the first chamber rotates under the action of the high-pressure water jet from the high-pressure nozzle 18, while water is injected into the first chamber and flows out from the outlet 14. The wastewater to be filtered is injected into the filter end of the rotating water injection filter assembly 2 through the inlet pipe 17. The filter end of the rotating water injection filter assembly 2 discharges the filtered wastewater into the second chamber and flows out from the outlet 15. The pollutants filtered by the filter end of the rotating water injection filter assembly 2 flow into the third chamber. At the same time, the rotation of the rotating water injection filter assembly 2 drives the cleaning assembly 3 to operate, and the cleaning assembly 3 cleans the pollutants in the third chamber.

[0048] By separating the wastewater filtered by the rotating water injection filter assembly 2 with the water sprayed from the high-pressure nozzle 18 through the separate discharge of the three chambers, the problem of pollution of clean water caused by the mixing of two types of water in the prior art is solved.

[0054] When this utility model is in use, the water flow sprayed from the high-pressure nozzle 18 drives the blade 212 to rotate, the blade 212 drives the rotating sleeve 211 to rotate, the rotating sleeve 211 drives the water injection ring 221 to rotate, the water injection ring 221 drives the rotating sleeve 225 to rotate, and the rotating sleeve 225 drives the conical filter cylinder 23 to rotate. At this time, the sewage in the liquid inlet pipe 17 flows into the ring groove 222 from the water injection hole 224 and is sprayed out from the spray hole 223. The sewage is sprayed into the inner end of the conical filter cylinder 23, and the sewage is thrown into the second chamber under the action of centrifugal force.

[0055] The cleaning assembly 3 includes a transmission ring 31, a belt 32, a timing pulley 33, a second rotating shaft 34, a first connecting rod 35, a second connecting rod 36, a mounting rod 37, and a scraper 38;

[0056] The transmission ring 31 is fixedly installed on the outer wall of the rotating sleeve 225. The rotating shaft 24 is rotatably connected to the inner wall of the third cavity.

[0058] There are two scraper blades 38, which are fixedly installed on the front and rear side walls of the mounting rod 37 respectively.

[0059] When this utility model is in use, the rotating sleeve 225 rotates while driving the transmission ring 31 to rotate. The transmission ring 31 drives the synchronous pulley 33 to rotate through the belt 32. The synchronous pulley 33 drives the rotating shaft 2 34 to rotate. The rotating shaft 2 34 drives the connecting rod 1 35 to rotate. The connecting rod 1 35 drives the connecting rod 2 36 to move. The connecting rod 2 36 drives the mounting rod 37 to slide back and forth on the inner wall of the third cavity. The scrapers 38 on both sides of the mounting rod 37 push the pollutants at the bottom of the third cavity to the liquid outlets 3 16 on the front and rear sides, thereby accelerating the discharge of pollutants from the liquid outlets 3 16.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
