Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the cyclone desander of the utility model; Figure 2 It is a schematic diagram of the cross-sectional structure of the cyclone desander of the utility model.

[0022] In a specific embodiment of the present invention, Figures 1-2 As shown, it includes a desanding tank body 1, an auger 2 and a water diversion pipe 3, the water diversion pipe 3 is fixedly connected to the middle hole of the auger 2, the length of the water diversion pipe 3 is greater than the length of the auger 2, the auger 2 is fixedly connected to the inner wall of the desanding tank body 1, the water inlet pipe 101 of the desanding tank body 1 is connected to the cavity between the blades of the auger 2, and also includes a floating coil 4, a vertical pipe 5 and a first filter plate 6, a plurality of first filter holes 401 are provided on the upper surface of the tube wall at the lower part of the floating coil 4, the floating coil 4 is spirally wrapped around the vertical pipe 5, the top end of the vertical pipe 5 is connected to the top end of the floating coil 4, and the outlet at the bottom end of the floating coil 4 is arranged downward; the bottom end of the vertical pipe 5 is connected to the water outlet at the top end of the water diversion pipe 3; the first filter plate 6 is detachably connected to the inner wall of the desanding tank body 1, and the first filter plate 6 is located above the floating coil 4.

[0023] Specifically, an annular retaining ring is welded inside the sand removal tank body 1, and the first filter plate 6 is bolted to the annular retaining ring. The first filter plate 6 is specifically a quartz sand filter plate, which uses quartz sand as a filter medium. Under a certain pressure, water with high turbidity is filtered through a certain thickness of granular or non-granular quartz sand, effectively intercepting and removing suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water, and finally achieving the effect of reducing water turbidity and purifying water quality. The sand removal tank body 1 belongs to the prior art, such as the support legs and the valve for sand discharge set at the bottom end of the sand removal tank body 1, the water outlet pipe set at the top of the sand removal tank body 1 for discharging filtered water, and the water inlet pipe 101 set along the tangent direction of the inner wall of the sand removal tank body 1, which belong to the prior art and will not be repeated. After the water flows into the floating coil 4 from the water diversion pipe 3, it flows in a spiral in the floating coil 4, and the water flows impact the inner wall of the floating coil 4, so the floating coil 4 can vibrate; in order to enhance the vibration effect of the floating coil 4, the inner diameter of the floating coil 4 is smaller than the inner diameter of the water diversion pipe 3, so the flow rate of the water will be accelerated when it enters the floating coil 4 from the water diversion pipe 3, and the impact of the water flow on the inner wall of the floating coil 4 becomes stronger, so the vibration effect of the floating coil 4 is enhanced. When the water flows in the pipe at the lower part of the floating coil 4, the water passes through the first filter hole 401, and the fine sand is blocked by the first filter hole 401, and finally the fine sand is discharged downward from the bottom outlet of the floating coil 4.

[0024] It also includes a second filter plate 7, which is coaxially arranged in the inner cavity of the desanding tank body 1, and is fixedly connected to the floating coil 4. The second filter plate 7 is located below the floating coil 4, and the second filter plate 7 is located above the auger 2. The bottom outlet of the floating coil 4 passes through the second filter plate 7; there is a movable margin between the second filter plate 7 and the inner wall of the desanding tank body 1, and there is a movable margin between the second filter plate 7 and the outer wall of the water diversion pipe 3.

[0025] Specifically, the bottom outlet of the floating coil 4 is welded to the second filter plate 7 , a connecting rod 701 is welded to the upper surface of the second filter plate 7 , and the top end of the connecting rod 701 is welded to the outer wall of the floating coil 4 .

[0026] A second filter hole 301 is provided at the bottom end of the water diversion pipe 3 .

[0027] Specifically, in the prior art, the bottom end of the water diversion pipe 3 is usually in the form of an opening. The utility model replaces the opening with a second filter hole 301 opened on the pipe wall, and the coarse sand is filtered by the second filter hole 301. The second filter hole 301 is larger than the filter hole of the second filter plate 7, the filter hole of the second filter plate 7 is larger than the first filter hole 401, and the first filter hole 401 is larger than the filter hole of the first filter plate 6; the coarse sand is filtered by the second filter hole 301, the fine sand is blocked by the first filter hole 401, and the finer sand passes through the first filter hole 401, and the finer sand is filtered by the first filter plate 6. The second filter plate 7 has a disturbing effect, which can prevent the water flow below it from driving the water flow above it to rotate, so that the finer sand will not be stirred, which facilitates the finer sand to sink from the filter hole of the second filter plate 7 to the bottom of the second filter plate 7.

[0028] The desanding tank body 1 comprises an upper tank body 102 and a lower tank body 103 , which are sealed and connected via flanges, and sealing rings or sealing gaskets are arranged at the flange joint surfaces; the floating coil 4 is located in the inner cavity of the upper tank body 102 .

[0029] It also includes an auger conveyor 8, which is connected to a sand discharge pipe at the bottom end of the sand removal tank body 1; a discharge port of the auger conveyor 8 is arranged to be inclined downward.

[0030] Specifically, when discharging sand, the auger conveyor 8 is started, the valve on the sand discharge pipe is opened, the sand flows down from the sand discharge pipe and enters the auger conveyor 8, and the auger conveyor 8 discharges the sand from the discharge port. The auger conveyor 8 belongs to the prior art, and its structure is not described in detail in this specification.

[0031] The utility model discloses a cyclone desander with working principle: water containing sand is pumped into the desander tank body 1 through the water inlet pipe 101 at a certain pressure by an externally arranged pump. Since the water inlet pipe 101 is arranged along the tangential direction of the inner wall of the desander tank body 1, when the water enters the inner cavity of the desander tank body 1, the water forms a surrounding fluid obliquely downward along the tangential direction of the inner wall of the desander tank body 1, and the water flow rotates and moves downward. When the water flow reaches the bottom of the desander tank body 1, it turns to rotate upward along the axis of the desander tank body 1. The water flow enters the water guide pipe 3 from the second filter hole 301 of the water guide pipe 3 and then enters the floating coil 4. At the same time, the coarse sand is filtered by the second filter hole 301, and then the water flows in the floating coil 4 in a spiral manner. The water flow impacts the inner wall of the floating coil 4, so that the floating coil 4 can vibrate.

[0032] When the water flows in the pipe at the bottom of the floating coil 4, the water passes through the first filter hole 401, and then is filtered by the first filter plate 6 and discharged from the water outlet pipe at the top of the desanding tank body 1. The fine sand is blocked by the first filter hole 401, and finally the fine sand is discharged downward from the outlet at the bottom end of the floating coil 4 and falls on the blades of the auger 2. The fine sand flows along the auger 2 to the bottom of the desanding tank body 1;

[0033] If the fine sand is stuck in the first filter hole 401 , the floating coil 4 can vibrate the fine sand stuck in the first filter hole 401 to prevent the fine sand from blocking the first filter hole 401 .

[0034] Under the action of fluid inertia centrifugal force and its own gravity, the sand falls to the bottom of the equipment along the inner wall of the sand removal tank body 1. After a certain period of time, a large amount of sand is accumulated in the sand removal tank body 1. At this time, the sand can be discharged. When discharging the sand, the auger conveyor 8 is started, and the valve on the sand discharge pipe is opened. The sand flows down from the sand discharge pipe and enters the auger conveyor 8, and the auger conveyor 8 discharges the sand from the discharge port.

The same or similar parts between the embodiments can be referred to each other, and the embodiments can be combined with each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
