Abstract
Description
Technical Field
[0001] This invention relates to the field of decommissioned wind turbine blade recycling technology, and in particular to a sand-water separation system. Background Technology
[0002] The lifespan of wind turbine generators is generally 20-25 years. Abandoned wind turbines can be recycled and reused, with recyclable parts including the base, tower, generator components, and turbine blades. However, when recycling turbine blades, due to their large size, they need to be cut. This cutting process typically uses a bladed cutting machine, generating a large amount of dust and flying debris, requiring significant manpower and resources for cleanup and causing air pollution. While a high-pressure water jet cutting technology is disclosed in related technologies, it has not been applied to wind turbine blade cutting. Furthermore, cutting thick and hard materials like wind turbine blades using only water is very difficult. Currently, there are no publicly available documents on using a water-sand mixture for jet cutting.
[0003] Solid-liquid separation devices are widely used in various fields to separate water and solids from the mixed liquid collected after cutting. Currently, there are no solid-liquid separation devices applied in the field of high-pressure waterjet cutting to separate and collect water and sand separately. Summary of the Invention

[0006] In some embodiments, the cyclone separator is inclined, and the positions of the feed inlet and water outlet of the cyclone separator are higher than the position of the sand outlet.
[0007] In some embodiments, the cyclone separator is detachably fixed to the bracket by clamps.
[0008] In some embodiments, the sand outlet of the cyclone separator is connected to a protective cover.

[0016] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0017] The sand-water separation system of the present invention is described below with reference to the accompanying drawings.
[0018] like Figure 1As shown in the figure, an embodiment of the present invention proposes a sand-water separation system, including: a support frame, a hydrocyclone separator 1, and a sand recovery box 5. The hydrocyclone separator 1 is detachably and fixedly installed on the support frame. The hydrocyclone separator 1 has a feed inlet, a water outlet, and a sand outlet. The feed inlet of the hydrocyclone separator 1 is connected to a feed pipe 15, and a pump body 16 is connected to the feed pipe 15. The water outlet of the hydrocyclone separator 1 is connected to a return water pipe 10, and the return water pipe 10 is connected to a water pump. The sand recovery box 5 is located directly below the sand outlet of the hydrocyclone separator 1.
[0019] This invention embodiment uses a cyclone separator 1, a sand recovery box 5, and a return water pipe 10 to separate the water and sand mixture after high-pressure jet cutting, and collect the sand and water through the sand recovery box 5 and the return water pipe 10 respectively, which facilitates later recycling.
[0020] In some embodiments, the hydrocyclone 1 is inclined, and the positions of the feed inlet and water outlet of the hydrocyclone are higher than the position of the sand outlet.
[0021] After the material enters the cylinder, the larger sand particles are thrown to the outside by centrifugal force, while the water is inside the vortex. Since the return water pipe 10 is connected to the water pump, the separated water will be pumped out through the return water pipe 10. The sand particles slide down the inclined angle due to their own weight and are discharged from the sand outlet into the sand recovery box 5.
[0022] In some embodiments, the cyclone separator 1 is detachably and fixedly connected to the bracket by clamps 3. This facilitates the assembly and disassembly of the cyclone separator 1.
[0023] In some embodiments, the sand outlet of the cyclone separator 1 is connected to a protective cover 4. This prevents sand from splashing onto the outside of the sand recovery box 5 during discharge.
[0024] In some embodiments, the feed end of the feed pipe 15 and the outlet end of the return water pipe 10 are respectively connected to a steel wire hose 13. The steel wire hose 13 can be bent freely, making it easy to connect to the water tank and the collection tank.
[0025] In some embodiments, pressure gauges 17 are connected to the feed pipe 15 and the return water pipe 10, respectively, to facilitate pressure monitoring of the feed pipe 15 and the return water pipe 10.
[0026] In some embodiments, the return water pipe 10 is fixedly connected to the bracket by a pressure ring. This prevents the return water pipe 10 from vibrating or moving.
[0027] In some embodiments, a sand discharge port is provided on one side of the sand recovery box 5 near the bottom, and the sand discharge port is connected to a pipe plug 6. When it is necessary to feed sand into the sand supply device, the pipe plug 6 is opened, and the pipeline and sand pump are connected.
[0028] In some embodiments, the bracket includes a base plate 9, an upright 8, a bracket 2, a fixed frame 12, and a support frame 14. The upright 8 is fixedly connected to the upper end of the base plate 9. The bracket 2 is fixedly connected to the top of the upright 8 and is inclined. The cyclone separator 1 is detachably fixedly connected to the bracket 2 by a clamp 3. The support frame 14 is fixedly connected to the side of the upright 8. The support frame 14 is detachably mounted with an electrical control box 7. The electrical control box 7 is electrically connected to the pump body 16, the water pump, and the pressure gauge 17, respectively. The return water pipe 10 is fixedly connected to the fixed frame 12 by a pressure ring.
[0029] The electrical control box 7 can adjust the flow rate, power and other parameters of the pump body 16 and the water pump according to the pressure value received from the pressure gauge 17.
[0030] In some embodiments, mounting feet 11 are fixedly connected to the four corners of the base plate 9. The bracket can be detachably and fixedly connected to the ground or equipment platform by bolts.
