DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0025] The utility model provides a high-efficiency and energy-saving hydrocyclone, including a hydrocyclone body 1, the top of which is circumferentially distributed with feed pipes 4. By setting a plurality of feed pipes 4, the hydrocyclone can reduce the impact force of the fluid to be separated on the inner wall of the hydrocyclone when in use, thereby extending the service life of the hydrocyclone. In the present application, a wear-resistant plate 23 is fixed to the inner wall of the hydrocyclone body 1. By setting the wear-resistant plate 23, the fluid entering the hydrocyclone is in direct contact with the wear-resistant plate 23, so that when the hydrocyclone is in use, only the wear-resistant plate 23 needs to be replaced, and the hydrocyclone body can be reused, thereby saving resources. An isolation pad is fixed to the outer wall of the wear-resistant plate 23, and the isolation pad can be made of rubber. By setting the isolation pad, the resilience of the isolation pad can buffer the impact force on the wear-resistant plate, thereby reducing the impact of the impact force on the hydrocyclone body 1.

[0026] The inner cavity of the feed pipe 4 is evenly and movably connected with a stirring rod 5. Through the setting of the stirring rod 5, the stirring rod 5 can stir the fluid in the feed pipe 4 when it rotates, so that different components in the fluid can be initially separated, thereby improving the separation efficiency of the hydrocyclone for the fluid.

[0027] A synchronous wheel 6 is fixed to the top of each stirring rod 5 in the feed pipe 4, and two adjacent synchronous wheels 6 are connected by a synchronous belt 16. In this way, when one stirring rod 5 in the feed pipe 4 rotates, the other stirring rods 5 in the feed pipe 4 can also rotate using the synchronous wheel 6 and the synchronous belt 16.

[0028] A connecting rod 7 is fixed to the top of a synchronous wheel 6 in the feed pipe 4, and a synchronous wheel 2 8 is fixed to the top of the connecting rod 7. When the synchronous wheel 2 8 rotates, the synchronous wheel 2 8 can drive the synchronous wheel 6 to rotate through the connecting rod 7, and the synchronous wheel 6 drives the stirring rod 5 fixedly connected thereto to rotate.

[0029] An overflow pipe 2 is fixed to the top of the hydrocyclone body 1, and an underflow pipe 3 is fixed to the bottom of the hydrocyclone body 1. The inner diameter of one end of the overflow pipe 2 away from the hydrocyclone body 1 is smaller than the inner diameter of the other end, and the inner diameter of one end of the underflow pipe 3 away from the hydrocyclone body 1 is smaller than the inner diameter of the other end. With this arrangement, the velocity of the fluid discharged from one end of the hydrocyclone body 1 of the overflow pipe 2 can be increased, and the velocity of the fluid discharged from the end of the underflow pipe 3 away from the hydrocyclone body 1 can be increased.

[0030] The high-efficiency and energy-saving hydrocyclone disclosed in the present application also includes an upper transmission structure 11 and a lower transmission structure 14. The upper transmission structure 11 is fixed on the top of the hydrocyclone body 1, and the lower transmission structure 14 is located on one side of the bottom end of the hydrocyclone body 1. The middle of the inner cavity of the upper transmission structure 11 and the lower transmission structure 14 are both movably connected with a turbine 22, a connecting pipe 12 is fixed on one side of the upper transmission structure 11, and the other end of the connecting pipe 12 is connected to the end of the overflow pipe 2 away from the hydrocyclone body 1, and a discharge pipe 18 is provided on the other side of the upper transmission structure 11; a connecting pipe 2 15 is fixed on one side of the lower transmission structure 14, and the other end of the connecting pipe 2 15 is connected to the end of the bottom flow pipe 3 away from the hydrocyclone body 1, and a discharge pipe 2 19 is provided on the other side of the lower transmission structure 14.

[0031] From the above description of the upper transmission structure 11 and the lower transmission structure 14, it can be seen that the fluid discharged through the overflow pipe 2 is divided into two paths, one path enters the inner cavity of the upper transmission structure 11 along the connecting pipe 1 12, and the fluid entering the upper transmission structure 11 can drive the turbine 22 to rotate and is discharged through the discharge pipe 1 18; the other path of fluid is discharged from the end of the overflow pipe 2 away from the hydrocyclone body 1; the fluid discharged through the underflow pipe 3 is divided into two paths, one path enters the inner cavity of the lower transmission structure 14 along the connecting pipe 2 15, and the fluid entering the lower transmission structure 14 drives the turbine 22 in the lower transmission structure 14 to rotate and is discharged through the discharge pipe 2 19, and the other path is discharged from the end of the underflow pipe 3 away from the hydrocyclone body 1; that is, when the upper transmission structure 11 and the lower transmission structure 14 are in use, they are driven by the separated fluid as a power source.

[0032] The middle part of the top of the turbine 22 in the upper transmission structure 11 is fixedly connected with a synchronous wheel 3 10, and the synchronous wheel 3 10 is connected to the synchronous wheel 2 8 through a synchronous belt 2 9. Through the setting of the synchronous wheel 3 10, the rotation of the turbine 22 can drive the stirring rod 5 to rotate, that is, the power source of the stirring rod 5 in the present application is the separated fluid, so that when the stirring rod 5 is working, there is no need to set up another power source, saving energy.

[0033] The bottom of the turbine 22 in the upper transmission structure 11 is fixedly connected with a connecting rod 2 17, and the connecting rod 2 17 is movably connected to the upper transmission structure 11. The bottom of the connecting rod 2 17 is fixedly connected to the top of a stirring rod 5, and the bottom of the stirring rod 5 is fixedly connected with a connecting rod 3 13, and the bottom of the connecting rod 3 13 is fixedly connected to the top of the turbine 22 in the lower transmission structure 14, and the connecting rod 3 13 is movably connected to the lower transmission structure 14; through the setting of the connecting rod 3 13 and the connecting rod 2 17, the synchronous wheel 3 10 is driven by a dual power source to improve the rotation efficiency of the synchronous wheel 3 10.

[0034] The connecting pipe 1 12 and the connecting pipe 2 15 are both provided with a flow meter 21 and an electric ball valve 20, and the flow meter 21 is located on the side of the electric ball valve 20 close to the turbine 22. By setting the flow meter 21, the flow rate of the fluid entering the upper transmission structure 11 and the flow rate of the fluid entering the lower transmission structure 14 can be the same, so that the rotation speeds of the two turbines 22 are consistent, which is convenient for the rotation of the synchronous wheel 3 10.

The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0036] In summary: when the high-efficiency and energy-saving hydrocyclone is used, the fluid to be diverted enters the inner cavity of the hydrocyclone body 1 through multiple feed pipes 4, reducing the impact force of the fluid on the inner wall of the hydrocyclone body 1; and the fluid discharged through the overflow pipe 2 is divided into two paths, one of which enters the inner cavity of the upper transmission structure 11 along the connecting pipe 12, and the fluid entering the upper transmission structure 11 can drive the turbine 22 to rotate and be discharged through the discharge pipe 18; the other fluid is discharged from the end of the overflow pipe 2 away from the hydrocyclone body 1; the fluid discharged through the underflow pipe 3 is divided into two paths, one of which enters the inner cavity of the lower transmission structure 14 along the connecting pipe 2 15 The fluid entering the lower transmission structure 14 drives the turbine 22 in the lower transmission structure 14 to rotate, and is discharged through the discharge pipe 2 19, and the other way is discharged from the end of the underflow pipe 3 away from the hydrocyclone body 1; the turbine 22 drives the synchronous wheel 3 10 fixedly connected thereto to rotate, the synchronous wheel 3 10 drives the synchronous wheel 2 8 to rotate through the synchronous belt 2 9, the synchronous wheel 2 8 drives the synchronous wheel 1 6 connected thereto to rotate through the connecting rod 1 7, the synchronous wheel 1 6 drives the stirring rod 5 fixedly connected thereto to rotate, the stirring rod 5 stirs the fluid around it, so that the fluid entering the hydrocyclone body 1 is preliminarily separated, thereby improving the operating efficiency of the hydrocyclone.
