Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, specifically a wastewater purification hydrocyclone. Background Technology

[0002] A hydrocyclone is a device used for wastewater treatment. It separates solid particles and sediments from wastewater by rotating a stream of water. A hydrocyclone is typically a conical container with the inlet tangential to the container. Wastewater flows in through the inlet and rotates inside the container. Under the influence of centrifugal force and gravity, solid particles and sediments settle at the bottom of the container, while clean water flows out from the top. Hydrocyclones can be used in industrial wastewater treatment, municipal sewage treatment, food processing wastewater treatment, and other fields.

[0003] Chinese Utility Model Publication No. CN221191614U discloses a hydrocyclone for wastewater purification, comprising: a shell, an inlet pipe, and a sand reservoir; the shell is a shell structure with a cylindrical upper part and a conical lower part; the upper cover is fixed to the top surface of the shell by bolts; the outlet pipe is fixed to the upper cover by bolts, and a flushing pipe is welded and fixed to one side of the outlet pipe; the bracket is welded and fixed to the lower part of the upper cover around the filter screen; the rotating shaft is inserted and installed in the middle of the bracket as a rotating device, and the brush is fixed to the upper end of the rotating shaft by screws, and the rotating blades are welded and fixed to the outer wall of the lower end of the rotating shaft.

[0004] This device uses water-driven rotating blades to rotate the brush and bristles to clean the filter. However, due to the continuous rotation caused by the water flow, the brush and bristles remain constantly rotating, while the filter is far from being properly cleaned. The bristles experience excessive wear and tear from prolonged friction with the filter. Furthermore, the rotating bristles exert radial tangential force against the water discharged from the filter, and because they rotate in one direction, the bristles become misaligned, reducing their contact with the filter and even causing them to deviate from the filter, thus failing to clean it. Therefore, its practicality is not very good, and there is room for improvement. Utility Model Content

A filter screen is installed at the bottom of the top cover, and a support frame is provided at the bottom of the top cover. A drive rod is rotatably installed in the middle of the support frame, and a motor for driving the drive rod to rotate is installed at the lower part of the drive rod. A cleaning brush for cleaning the filter screen is provided at the upper part of the drive rod. The cleaning brush includes a brush and bristles, with one end of the bristles abutting against the side wall of the filter screen. When rotating left and right, it cleans away impurities on the filter screen.

[0009] Furthermore, the motor is externally fitted with a waterproof housing, and a cover is sealed on the upper part of the waterproof housing. The cover and the drive rod are rotatably mounted together by a mechanical seal.

[0010] Furthermore, the side wall of the waterproof shell is provided with a connecting plate, the upper part of the connecting plate is provided with a through hole, and a bolt is installed through the through hole.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a hydrocyclone for wastewater purification, which has the following beneficial effects:

[0016] This wastewater purification hydrocyclone allows the motor to be started at a specified time via a manual control panel, driving the brush to rotate and clean the filter screen. This avoids excessive wear and tear caused by the brush constantly rotating to clean the filter screen. Furthermore, by controlling the motor's forward and reverse rotation, the brush can be rotated in either direction, preventing it from rotating in one direction for an extended period and causing it to tilt due to tangential force with the water flow. This improves the contact effect between the brush and the filter screen, thereby enhancing its practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the prior art, a sewage purification hydrocyclone includes a shell 1, an inlet pipe 2, a sand reservoir, a drain valve, support legs, a top cover 3, an outlet pipe, and a flushing pipe 4. This is the prior art and will not be elaborated on here.

[0023] Please see Figure 1-3 This utility model discloses a wastewater purification hydrocyclone. A filter screen 5 is installed at the bottom of the upper cover 3. Water from the inlet pipe 2 enters the filter screen 5 for filtration. A support frame 6 is provided at the bottom of the upper cover 3, positioned outside the filter screen 5. A drive rod 7 is rotatably mounted in the middle of the support frame 6 via a rotating shaft, bearing, or bushing. A motor 8 is installed at the lower part of the drive rod 7 to drive its rotation. Starting the motor 8 causes it to rotate, driving the drive rod 7 to rotate. A cleaning brush is provided at the upper part of the drive rod 7 for cleaning the filter screen 5. The rotation of the drive rod 7... The cleaning brush rotates and rubs against the filter screen 5, cleaning away impurities on the filter screen 5. The cleaning brush includes a brush 9 and bristles 10. The drive rod 7 is located at the bottom of the brush 9. When the brush 9 rotates, it drives the bristles 10 to rotate. One end of the bristles 10 abuts against the side wall of the filter screen 5, making it easy to clean away impurities on the filter screen 5. When rotating left and right, it cleans away impurities on the filter screen 5. When the bristles 10 rotate in one direction, the bristles 10 are tangentially forced by the water and become skewed. Then, when rotating in the opposite direction, the skewed bristles 10 are subjected to a reverse tangential force and return to their original state.

[0024] The motor 8 is equipped with a waterproof shell 11 to isolate the motor 8 from external water. The upper part of the waterproof shell 11 is sealed with a cover, and the cover and the drive rod 7 are rotatably mounted together by a mechanical seal. When the motor 8 rotates, the drive rod 7 rotates on the cover.

[0025] The side wall of the waterproof shell 11 is provided with a connecting plate 12. The upper part of the connecting plate 12 is provided with a through hole, and a bolt is installed through the through hole. The lower part of the support frame 6 is provided with a threaded hole corresponding to the bolt, and the threaded hole and the bolt are threaded together. The bolt is passed through the through hole on the connecting plate 12 and then screwed into the threaded hole at the lower part of the support frame 6, thereby installing the waterproof shell 11 at the lower part of the support frame 6.

[0026] A protective cover 13 is installed on the lower part of the top cover 3. A battery 14 is installed inside the protective cover 13 and is electrically connected to the motor 8. The battery 14 is used to provide power to the motor 8.

[0027] A control panel 15 is installed on the outer wall of the housing 1, and the control panel 15 and the battery 14 are electrically connected to the motor 8. The operator can start the motor 8 at a specified time through the control panel 15, rotating it forward or backward to drive the cleaning brush to clean the filter screen 5.

[0028] In this technical solution, the control panel 15, motor 8 and battery 14 are all existing technologies. This technical solution only uses them without improving their connection methods and components. Their connection methods and working methods are all existing technologies and will not be elaborated on here.

[0029] In summary, when using this wastewater purification hydrocyclone, the operator sets the cleaning program via the control panel 15 on the outer wall of the housing 1: the start time, forward and reverse rotation cycle, and running time of the motor 8 can be set (for example, setting it to start once every 30 minutes, rotating forward for 30 seconds and then reverse for 30 seconds). After the set time is reached, the control panel 15 triggers the motor 8 to start, the battery 14 supplies power to the motor 8, the motor 8 drives the drive rod 7 to rotate, and the cleaning brush (brush 9 and bristles 10) on the upper part of the drive rod 7 rotates synchronously with it. When the motor 8 rotates forward, the bristles 10 are tilted due to the tangential force generated by the water flow, and perform preliminary cleaning of the impurities on the side wall of the filter screen 5. When the motor 8 rotates in reverse, the tilted bristles 10 are restored to their original shape by the reverse tangential force, and further clean the remaining impurities on the filter screen 5 through friction, ensuring smooth filtration.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
