Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater pretreatment device with a cyclone separation structure. Background Technology

[0002] Industrial and domestic wastewater often contains particulate matter, which may include suspended solids, colloids, and sediments. These particles may contain various toxic and harmful substances, such as heavy metals and organic matter. The presence of particulate matter not only affects the transparency and aesthetics of wastewater but can also damage aquatic ecosystems, impacting the survival and reproduction of aquatic organisms. Furthermore, particulate matter may carry pathogens and parasites, posing a potential threat to human health.

[0003] Patent document CN207659143U discloses a high-efficiency hydrocyclone sand separator for water treatment, including an outer cylinder, an inner cylinder, an inlet pipe, an outlet pipe, a sand collection hopper, an ash discharge valve, and support legs. An inlet pipe is located on one side of the upper part of the inner cylinder, tangentially connected to the side wall of the inner cylinder. An outer cylinder is located on one side of the inner cylinder. The inner cylinder divides the interior of the hydrocyclone sand separator into a hydrocyclone sand removal zone and a settling zone. The area inside the inner cylinder is the hydrocyclone sand removal zone, and the area between the inner and outer cylinders is the settling zone. An outlet pipe is located on the upper part of the outer cylinder. The top of the outer cylinder is flush with the top of the inner cylinder, and the bottom of the outer cylinder is lower than the bottom of the inner cylinder. A conical sand collection hopper is located on one side of the lower part of the outer cylinder, and an ash discharge valve is located on one side of the lower part of the sand collection hopper. Several support legs are located on one side of the outer cylinder. This invention divides the interior of the hydrocyclone sand separator into a hydrocyclone sand removal zone and a settling zone through the inner cylinder, allowing the wastewater after hydrocyclone sand removal to undergo gravity settling again, thus enhancing the sand removal effect.

[0030] In this embodiment, a valve 6 is further provided at one of the inlet pipes and one of the outlet pipes. The valve controls the flow of water through the inlet pipe and the outlet pipe. The valve is opened and closed periodically to flush the deposited particles in the sedimentation tank, which has a better cleaning effect and avoids affecting the wastewater treatment effect.

[0031] Example 2:

[0032] In this embodiment, as Figure 1-2As shown, the present invention proposes a wastewater pretreatment device with a cyclone separation structure, comprising an upper cylinder 1, an inner pipe 2, a lower cylinder 3, and a sedimentation tank 4. The bottom of the upper cylinder is provided with a flange 11, the middle of the inner pipe is provided with a fixing plate 21, and the top of the lower cylinder is provided with a flange 31. The flange 1, the fixing plate, and the flange 2 are correspondingly arranged and connected by bolts.

Both the inlet pipe 1 and the outlet pipe 1 are connected to a wastewater pool. Water enters from the inlet pipe 1 to flush out the particles deposited in the sedimentation tank.

[0033] In this embodiment, the upper cylinder is further configured to have a second water outlet pipe 12 on its side, and a fifth flange 13 at the end of the second water outlet pipe. The second water outlet pipe is connected to the wastewater post-treatment equipment through a connecting pipe.

[0034] In this embodiment, a gasket 5 is further provided between the fixed plate and flange one and flange two, and the gasket is used to improve the sealing performance.

[0035] In this embodiment, the lower cylinder is further configured to include a coarse-diameter section 33, a tapered section 34, and a fine-diameter section 35, all integrally formed. The top of the tapered section is connected to the bottom of the coarse-diameter section, and the bottom of the tapered section is connected to the top of the fine-diameter section. A spiral flow channel can be provided on the inner wall of the lower cylinder to improve the swirling effect.

[0036] In this embodiment, the water inlet pipe 2 36 is provided on the side of the coarse diameter section, the water inlet pipe 2 is tangent to the connection of the coarse diameter section, the end of the water outlet pipe 2 is provided with flange 6 37, and the water inlet pipe 2 is connected to the wastewater tank through a connecting pipe.

The valve is opened and closed periodically to flush the deposited particles in the sedimentation tank, which has a better cleaning effect and avoids affecting the wastewater treatment effect.

[0038] The working principle of this wastewater pretreatment equipment with a vortex separation structure is as follows: wastewater enters the lower cylinder through the connecting pipe from the inlet pipe 2. Since the connection between the inlet pipe 2 and the lower cylinder is tangential, the wastewater forms a rotating vortex in the lower cylinder. The rotational speed in the vortex generates centrifugal force, causing the particulate matter and liquid to separate under the action of centrifugal force. The particulate matter settles and falls into the sedimentation tank. The water flows from bottom to top along the inner pipe and enters the wastewater post-treatment equipment through the outlet pipe 2 and the connecting pipe. The particulate matter in the sedimentation tank is periodically flushed by the water flow to avoid affecting the wastewater treatment effect.
