Description

Technical Field

[0001] The utility model relates to the technical field of hydrocyclone separation devices, in particular to a multi-stage hydrocyclone separation device. Background Art

[0002] The hydrocyclone separator is a water-based dirty coolant that enters the vortex separator at a certain speed from the inlet. Usually, multiple hydrocyclones are connected to separate the dirty water.

[0003] The bottom drain pipe of the existing hydrocyclone separator is generally not equipped with an anti-clogging mechanism, and its bottom outlet is easily blocked by impurities in the sewage such as dust. When the bottom outlet of the hydrocyclone separator is blocked, the water flow will immediately flow back, causing the water in the hydrocyclone separator to flow to the clean water outlet at the upper end, causing the separated clean water to be contaminated again, requiring the clean water to be separated again, and increasing the water separation time. Utility Model Content

[0004] In view of the above problems, the utility model provides a multi-stage hydrocyclone separation device for solving the problem that the separated clean water is contaminated again when the bottom outlet of the hydrocyclone separator is blocked.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A multi-stage hydrocyclone separation device comprises a plurality of cyclone tubes, wherein the upper part of the cyclone tubes is a water inlet pipe and a clean water pipe, and the lower part is a sewage pipe. Two adjacent cyclone tubes are connected to the water inlet pipe through the sewage pipe. The device is characterized in that it also comprises a connecting pipe, wherein the top of the connecting pipe is connected to the sewage pipe of the upper cyclone tube, and the bottom is connected to the water inlet pipe of the lower cyclone tube. A debris clearing mechanism is arranged in the connecting pipe, and the debris clearing mechanism comprises two symmetrically distributed fixing rods, the tops of the two fixing rods are fixed on the inner wall of the connecting pipe, a fixing ring is horizontally installed at the bottom, a rotating shaft is vertically installed on the fixing ring, a spiral fan blade is arranged on the rotating shaft, a chain is arranged on the top of the rotating shaft, a plurality of scraping rods are vertically arranged on the chain, and the scraping rods are in contact with the inner wall of the sewage pipe of the upper cyclone tube.

[0007] There is a top cone on the top of the shaft

[0008] The bottoms of the fixing rod and the connecting rod are both provided with a plurality of through holes.

[0009] A semicircular groove is provided on the inner wall of the fixing rod, a rotating rod is installed on the semicircular groove through a limiting block, the rotating rod can rotate in the semicircular groove, and the limiting block is in a U-shape.

[0010] The maximum distance between the two fixing rods is greater than the bottom end diameter of the cyclone tube.

[0011] The beneficial effects of the utility model are:

[0012] (1) When the utility model is in use, two adjacent cyclone tubes are connected to the water inlet pipe through a sewage pipe, and a debris clearing mechanism in the pipe is connected to prevent the separated clean water from being polluted again, thereby realizing efficient and high-quality separation of dirty water and impurities. When the water flow impacts the spiral blades on the rotating shaft, the spiral blades drive the rotating shaft, and the rotating shaft drives the scraper rod to rotate. The scraper rod contacts the inner wall of the sewage pipe of the upper cyclone tube to remove the debris attached to the inner wall of the sewage pipe.

[0013] (2) When the utility model is in use, the top cone at the top of the rotating shaft prevents water flow from directly impacting the rotating shaft, thereby reducing the impact force of water on the debris clearing mechanism and protecting the internal structure of the device.

[0014] (3) When the utility model is in use, a plurality of through holes are provided at the bottom of the fixed rod and the connecting rod, and part of the water flows out through the through holes, thereby reducing the impact of the water flow on the fixed rod and the connecting rod.

[0015] (4) When the utility model is in use, a semicircular groove is provided on the inner wall of the fixed rod, and the rotating rod can rotate in the semicircular groove. The inner wall of the limit block is rotatably connected to the rotating rod. The limit block is in a U-shape. When water impacts the fixed rod, the water will first impact the rotating rod to rotate. The rotation of the rotating rod changes the direction of the impact force of the water directly on the fixed rod, thereby reducing the impact force of the water on the fixed rod.

[0016] (5) The maximum distance between the two fixing rods of the utility model is greater than the bottom diameter of the vortex tube, thereby avoiding the influence on the running stability of the spiral blades and the scraper rod. BRIEF DESCRIPTION OF THE DRAWINGS
