Specific implementation mode

[0024] The following uses specific embodiments to illustrate the present invention, but it is not a limitation of the invention.

[0025] Embodiment 1 As Figures 1-7 shown, in this embodiment, a water pollution centrifugal treatment equipment is provided, including a tank body 1 and a centrifugal cylinder 2.

[0026] An inner cavity 10 is provided inside the tank body 1. The inner cavity 10 is cylindrical. The cylindrical design of the inner cavity 10 is beneficial to the subsequent centrifugation and other operations, and ensures the uniformity of the fluid flow and treatment inside.

[0027] The centrifugal cylinder 2 divides the inner cavity 10 into a liquid inlet cavity 8 and a liquid discharge cavity 9. A liquid inlet pipe 11 is installed inside the liquid discharge cavity 9. The centrifugal cylinder 2 generates centrifugal force through rotation, so that the pollutants in the sewage entering the liquid inlet cavity 8 move towards the wall of the centrifugal cylinder 2 under the action of centrifugal force. The liquid inlet pipe 11 introduces the sewage into the liquid discharge cavity 9, and then flows into the liquid inlet cavity 8 to start centrifugal treatment, dividing the inner cavity 10 into different functional areas, making the sewage entry, treatment and discharge paths clear.

[0028] Among them, the bottom of the centrifuge tube is an arc surface. A plurality of air blowing heads 6 are installed at the top of the inner cavity 10. The air outlet channels of the air blowing heads 6 are attached to the inner wall of the centrifuge cylinder 2, and the air outlet direction is towards the bottom of the inner cavity 10. The arc surface design at the bottom of the centrifuge tube helps the sewage to move towards the tube wall under the action of centrifugal force and converge at the bottom. The air blown out by the air blowing heads 6 flows downward along the inner wall of the centrifuge cylinder 2, which can assist in blowing the pollutants attached to the inner wall of the centrifuge cylinder 2 towards the bottom. At the same time, it can also update the air flow inside the centrifuge cylinder 2 to avoid problems such as peculiar smells. The arc surface bottom is conducive to the collection of pollutants. The design of the air blowing heads 6 enhances the collection effect of pollutants. A waste outlet is provided at the bottom of the centrifuge cylinder 2, and a sealing structure is installed at the waste outlet. The waste outlet is communicated with the negative pressure chamber 31 outside the tank body 1. The gas discharged by the air blowing heads 6 can flow along the tube wall of the centrifuge cylinder 2 towards the negative pressure chamber 31. After centrifugal treatment, the pollutants gather at the bottom of the centrifuge cylinder 2. When the sealing structure is opened, under the action of the negative pressure chamber 31, the waste is discharged from the waste outlet. The gas blown out by the air blowing heads 6 flowing towards the negative pressure chamber 31 can further drive the pollutants towards the waste outlet. The method of discharging waste by negative pressure is efficient and clean, reducing the trouble of manual cleaning. The air flow circulation helps to improve the efficiency of pollutant discharge.

[0029] A liquid inlet pipe 11 is fixed in the middle of the tank body 1. The liquid inlet pipe 11 extends into the interior of the liquid inlet cavity 8. A plurality of liquid inlets are provided on the side wall of the liquid inlet pipe 11. The liquid inlet pipe 11 in the middle of the tank body 1 introduces sewage into the liquid inlet cavity 8. The plurality of liquid inlets on the side wall of the liquid inlet pipe 11 enable the sewage to enter the liquid inlet cavity 8 evenly, preparing for the subsequent centrifugal treatment. The even liquid inlet ensures that the sewage is evenly distributed in the liquid inlet cavity 8 during centrifugal treatment, improving the centrifugal treatment effect, and at the same time reducing the damage to the equipment caused by uneven local pressure.

[0030] Embodiment 2 As Figures 1-7 shown, on the basis of Embodiment 1, this embodiment provides the internal structure of the negative pressure chamber 3, which is specifically as follows: A negative pressure chamber 3 is fixed at the bottom of the tank body 1. The negative pressure chamber 31 is arranged inside the negative pressure chamber 3. A connecting pipe 4 is fixed at the bottom of the centrifuge cylinder 2. The connecting pipe 4 extends into the interior of the negative pressure chamber 3. The negative pressure chamber 3 at the bottom of the tank body 1 provides the negative pressure chamber 31. The connecting pipe 4 at the bottom of the centrifuge cylinder 2 communicates the waste outlet with the negative pressure chamber 31. The negative pressure generated by the negative pressure chamber 3 is used to extract the waste from the bottom of the centrifuge cylinder 2. The independent design of the negative pressure chamber 3 is convenient for centralized generation and control of negative pressure.

[0031] A circular pipe 5 is fixed on the top wall of the tank body 1. A plurality of air blowing heads 6 are connected to the circular pipe 5, and the lower ends of the air blowing heads 6 penetrate through the top wall of the tank body 1 and extend into the inner cavity 10. The circular pipe 5 on the top wall of the tank body 1 provides air source for the plurality of air blowing heads 6. The lower ends of the air blowing heads 6 penetrate through the top wall of the tank body 1 and extend into the inner cavity 10 to ensure that the blown air can accurately act on the inner wall of the centrifugal cylinder 2. The installation mode of the air blowing heads 6 enables the air flow to accurately act on the target position, improving the effect of assisting in cleaning pollutants.

[0032] A filter screen 17 is fixed on the outer side of the top of the negative pressure chamber 3. The filter screen 17 is attached to the outer circular part of the top in an inclined plane. An exhaust pipe 13 is connected to the negative pressure chamber 3, and the exhaust pipe 13 is connected to the outer side of the filter screen 17. The filter screen 17 on the outer side of the top of the negative pressure chamber 3 filters the gas discharged from the negative pressure chamber 3 to prevent impurities, etc. from being discharged. The exhaust pipe 13 is connected to the outer side of the filter screen 17 to extract the filtered gas, maintaining the negative pressure state of the negative pressure chamber 3. The filter screen 17 prevents the emission of polluted gas and protects the external environment. The design of the exhaust pipe 13 ensures that the negative pressure of the negative pressure chamber 3 can be continuously generated, ensuring the normal progress of the waste discharge work.

[0033] Embodiment III As Figures 1-7 shown, on the basis of Embodiment I and Embodiment II, this embodiment provides a sealing structure and a liquid discharge chamber 9, which are specifically as follows: The sealing structure includes a linear oil cylinder fixed at the bottom of the negative pressure chamber 3. The output end of the linear oil cylinder penetrates through the negative pressure chamber 3 and is connected with a plug column. The plug column can extend from the negative pressure chamber 3 into the waste outlet. The linear oil cylinder at the bottom of the negative pressure chamber 3 realizes the sealing and opening of the waste outlet by controlling the telescopic movement of the plug column. When it is necessary to discharge waste, the linear oil cylinder pushes the plug column out of the waste outlet to open the waste outlet; after the treatment is completed, the plug column is inserted into the waste outlet for sealing.

[0034] The plug column is rotatably connected to the output end of the linear oil cylinder, and a bearing 7 is installed at the rotating part. The rotational connection between the plug column and the output end of the linear oil cylinder and the installation of the bearing 7 reduce the friction with the waste outlet and ensure the sealing effect at the same time.

[0035] The bottom of the liquid discharge chamber 9 is a curved surface with the inner ring higher than the outer ring. A liquid outlet pipe 12 is fixed on the tank body 1, and the liquid outlet pipe 12 extends to the outer ring part, enabling the clean liquid after centrifugal treatment to flow naturally to the outside. The liquid outlet pipe 12 on the tank body 1 extends to the outer ring part to discharge the clean liquid, realizing the natural flow of the liquid by using the gravity effect, without additional power equipment, saving energy, and improving the liquid discharge efficiency and the stability of the equipment operation at the same time.

[0036] A bearing 7 is fixed to the outside of the upper end of the centrifugal cylinder 2. The outer wall of the bearing 7 is fixed to the inner wall of the tank body 1. The bearing 7 outside the upper end of the centrifugal cylinder 2 is fixed to the inner wall of the tank body 1, providing support for the rotation of the centrifugal cylinder 2 and ensuring the stability of the centrifugal cylinder 2 during high-speed rotation. The use of the bearing 7 reduces the frictional resistance during the rotation of the centrifugal cylinder 2 and improves the operating efficiency of the equipment.

[0037] A toothed ring 14 is fixed to the outside of the connecting pipe 4. A gear 15 is rotatably installed in the bottom sandwich layer of the tank body 1. The gear 15 is meshed and connected with the teeth on the toothed ring 14. A motor 16 for driving the gear 15 to rotate is fixed to the tank body 1. The toothed ring 14 outside the connecting pipe 4 is meshed and connected with the gear 15 rotatably installed in the bottom sandwich layer of the tank body 1. The motor 16 on the tank body 1 drives the gear 15 to rotate, thereby driving the toothed ring 14, the connecting pipe 4 and the centrifugal cylinder 2 to rotate together. The transmission ratio of the gear 15 transmission method is accurate, and it can stably provide rotational power for the centrifugal cylinder 2. The motor 16 drive is convenient for controlling the rotation speed of the centrifugal cylinder 2 to meet the treatment requirements of different sewage.

[0038] Working principle: Sewage enters the liquid inlet cavity 8 through the liquid inlet pipe 11 in the middle of the tank body 1. Multiple liquid inlets on the side wall of the liquid inlet pipe 11 ensure the uniform distribution of sewage. The rotation of the centrifugal cylinder 2 generates a strong centrifugal force, causing the pollutants in the sewage to move towards the wall of the centrifugal cylinder 2, achieving preliminary separation.

[0039] The air blown out by the air blowing head 6 at the top of the inner cavity 10 flows downward along the inner wall of the centrifugal cylinder 2, assisting in blowing the pollutants attached to the cylinder wall towards the bottom. The bottom of the centrifugal cylinder 2 is an arc surface, which is conducive to the convergence of pollutants. The waste material outlet is communicated with the negative pressure cavity 31 outside the tank body 1. When the sealing structure is opened, under the action of negative pressure, the waste material is discharged from the waste material outlet. At the same time, the gas discharged from the air blowing head 6 flows towards the negative pressure cavity 31, further driving the pollutants to be discharged.

[0040] The clean liquid after centrifugal treatment naturally flows outward under the action of gravity due to the fact that the bottom of the liquid discharge cavity 9 is a curved surface with a higher inner ring and a lower outer ring, and is discharged through the liquid discharge pipe 12 located at the outer ring part of the tank body 1.

[0041] The motor 16 drives the gear 15 in the bottom sandwich layer of the tank body 1 to rotate. The gear 15 is meshed with the toothed ring 14 outside the connecting pipe 4, thereby driving the connecting pipe 4 and the centrifugal cylinder 2 to rotate. By controlling the rotation speed of the motor 16, the rotation speed of the centrifugal cylinder 2 can be adjusted to adapt to the treatment requirements of different sewage.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
