Description

Energy-saving and environmentally friendly wastewater treatment device

Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to an energy-saving and environmentally friendly wastewater treatment device.

Background technique

Existing energy-saving and environmentally friendly wastewater treatment devices need to mix wastewater with chemicals when treating wastewater. The wastewater contains garbage that cannot be decomposed by chemicals. The separation process of the treatment barrel and the mitigation equipment for storing garbage in the existing equipment is relatively cumbersome; the mixing efficiency of some equipment is low. For example, the existing patent (authorization announcement number: CN 219449359 U) is an energy-saving and environmentally friendly wastewater treatment device.

The mixing assembly in the equipment is driven by a motor to stir the wastewater inside the treatment barrel so that the wastewater and the wastewater treatment agent are fully mixed. However, multiple sets of mixing plates rotate in the same direction, so that the water flow rotates in the same direction, resulting in insufficient mixing of the water flow and the wastewater treatment agent. As a result, the wastewater may be discharged from the treatment barrel before it is completely treated, or the mixing time of the wastewater and the wastewater treatment agent needs to be prolonged, resulting in low wastewater treatment efficiency.

A scraping mechanism 6 is provided at the outer end of the stirring frame 53. The scraper 61 in the scraping mechanism 6 can scrape off the attachments on the inner wall of the shell 2 as the stirring frame 53 rotates, and can vibrate up and down during the scraping process to shake the attachments on the scraper 61 off to the bottom of the shell 2.

In this embodiment, the scraping mechanism 6 includes a scraper 61, and the inner sides of the upper and lower ends of the scraper 61 are provided with a slide groove 611, and the slide groove 611 is provided with a limit column 612. The upper and lower ends of the stirring frame 53 are provided with a block 63 that is slidably connected to the slide groove 611 and the limit column 612. The limit column 612 between the top of the slide groove 611 and the block 63 is sleeved with a spring 64. The top of the scraper 61 is rotatably connected to a roller 65, and the bottom surface circumference of the top cover 3 is arranged with a plurality of inclined blocks 66 corresponding to the roller 65. The inclined block 66 can push against the roller 65 to drive the scraper 61 to move downward, and the spring 64 is used to reset the scraper 61 to achieve the up and down shaking of the scraper 61.

In this embodiment, the frame 1 includes a base 11 and a top plate 12, the four corners of the base 11 are fixedly connected with columns 13, the top plate 12 is fixedly connected to the top of the columns 13, and the shell 2 is fixedly connected to the bottom plate.

In this embodiment, the lifting device 4 includes a lifting motor 41 and a screw sleeve 42. The lifting motor 41 is provided with two. The lifting motor 41 is fixedly connected to the top plate 12, and its output shaft is fixedly connected to a screw rod 43. The screw rod 43 is rotatably connected to the bottom plate and the top plate 12. The screw sleeve 42 is threadedly connected to the screw rod 43, and the screw sleeve 42 is fixedly connected to the top cover 3.

In this embodiment, the stirring rod 54 and the rod body on the stirring frame 53 are staggered to avoid interference.

In this embodiment, the bidirectional rotation mechanism 5 also includes a rotating motor 55, which is fixedly connected to the top cover 3, and its output shaft is fixedly connected to a driving bevel gear 56, and the upper and lower sides of the driving bevel gear 56 are respectively meshed with an upper bevel gear 57 and a lower bevel gear 58, the upper bevel gear 57 is fixedly connected to the inner shaft 52, and the lower bevel gear 58 is fixedly connected to the outer tube 51.

In this embodiment, a water inlet pipe 21 is provided on the outer circumference of the shell 2 , and a water outlet pipe 22 is provided at the bottom thereof. A filter frame 7 is provided at the bottom of the shell 2 .

Working process and principle:

When the device is in use, waste water enters the housing 2 from the water inlet pipe 21, and the water outlet pipe 22 is in a closed state. The top cover 3 is sealed on the housing 2.

The rotating motor 55 is started, driving the bevel gear 56 to drive the upper bevel gear 57 and the lower bevel gear 58 to rotate in different directions, and the outer tube 51 and the inner shaft 52 drive the rotating frame and the stirring rod 54 to stir the wastewater in the shell 2 in opposite directions, so that the wastewater and the chemical agent are fully mixed.

During the rotation of the stirring frame 53, since the block 63 on the stirring frame 53 is stuck in the slide groove 611, the scraper 61 can be driven to rotate synchronously. The rotation of the scraper 61 can clean the attachments on the inner wall of the shell 2. Some of the attachments will fall directly into the filter frame 7, and some of the attachments will adhere to the scraper 61. In order to avoid too much attachment on the scraper 61, the block 63 and the slide groove 611 are designed to be slidingly connected, and are reset by a spring 64. When the roller 65 on the scraper 61 contacts the inclined block 66, the inclined block 66 moves downward against the roller 65, and the scraper 61 moves downward with it. Then the roller 65 is separated from the inclined block 66, and the roller 65 and the scraper 61 are reset under the action of the spring 64. This reciprocating process causes the scraper 61 to vibrate up and down during its rotation, so that the attachments on the scraper 61 can be shaken into the filter frame 7.

After the wastewater treatment is completed, the drain pipe is opened and the wastewater is drained away. When the filter frame 7 needs to be cleaned, the lifting motor 41 drives the screw rod 43 to rotate, so that the screw sleeve 42 drives the top cover 3 to rise, and then the filter frame 7 can be taken out.

It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
