Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, specifically a vortex multi-stage filtration device for wastewater treatment. Background Technology

[0002] Hydrocyclones are currently widely used and relatively effective impurity classification devices, mainly used to separate impurities from turbid water. Their working principle is relatively simple. Structurally, a hydrocyclone consists of a feed pipe, a cylindrical outer shell, an overflow pipe, a conical container, and a sand settling nozzle. Turbid water, under pressure, enters the shell along the tangential direction of the cylinder through the feed pipe, where it rotates. Impurities in the turbid water are drawn to the periphery of the rotating flow due to the significant centrifugal force and flow downwards with the water, eventually being discharged from the sand settling nozzle at the bottom. Water at the center of the rotation flows out through the overflow pipe. Through multiple hydrocyclones connected in series, wastewater treatment is achieved.

[0003] However, when the water flows in a vortex-like swirling motion within the conical container, its velocity decreases significantly when it reaches the middle of the container compared to when it first enters. Consequently, when cleaning water containing viscous impurities, these impurities tend to adhere to the side walls of the conical container. When a certain amount of these impurities adhere, they affect the vortex-like flow, thus impacting the filtration effect. Existing hydrocyclones do not effectively address this issue.

[0004] Therefore, it is necessary to propose a vortex multi-stage filtration device based on wastewater treatment to solve the above-mentioned technical problems. Summary of the Invention

Beneficial effects

[0020] (1) The present invention uses a diverter impeller to drive a side wall cleaning device to clean the side wall of the middle part of the conical container, preventing impurities from easily adhering to the side wall of the conical container.

[0021] (2) In this invention, the shaking roller will roll into contact with the scraping wall sliding groove to generate rolling. At this time, the protrusion on the shaking roller will slide into the second reciprocating groove, thereby driving the shaking rod and the shaking slider to reciprocate. The shaking slider will drive the scraping mechanism on it to generate a shaking state, thereby improving the cleaning efficiency of the side wall of the cone-shaped device.

[0022] (3) The present invention utilizes a scraping strip made of elastic metal to press the scraping strip onto the side wall of the cone-shaped device. At the same time, it can bend according to the change of the diameter of the cross-section of the cone-shaped device, thereby improving the adhesion between the scraping strip and the side of the cone-shaped device, and further improving the cleaning effect on the side wall of the cone-shaped device.

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] A conical container 3 is fixedly installed at the lower end of the cylindrical outer shell 1, and the conical container 3 communicates with the cylindrical outer shell 1;

[0037] A sand settling outlet 4 is fixedly installed at the lower end of the conical container 3 and communicates with the conical container 3.

[0038] Overflow pipe 5, which is fixedly installed in the middle of the cylindrical outer shell 1 and extends into the conical container 3, with the outer end of the lower end of the overflow pipe 5 having an inclined surface;

[0039] The flow divider impeller 6 is rotatably connected to the overflow pipe 5. Flow divider blades 61 are fixedly connected to the flow divider impeller 6. Multiple flow divider blades 61 are evenly distributed along the circumference of the flow divider impeller 6.

[0040] Side wall cleaning device 7, which is disposed on the side wall of the conical container 3 and driven by the diverter impeller 6, and a plurality of side wall cleaning devices 7 are evenly distributed along the circumference of the conical container 3.

[0041] During the wastewater filtration process, turbid water, under external pressure, enters the shell along the tangent of the column through the feed pipe 2. It rotates within the shell, and impurities in the turbid water are drawn to the periphery of the rotating flow due to the significant centrifugal force. The impurities then flow downwards with the water and are eventually discharged from the bottom sand drain. The water at the center of the rotation flows out through the overflow pipe 5. During this process, the water impacts the diverting blades 61, causing the diverting impeller 6 to rotate. The diverting impeller 6 then drives the sidewall cleaning device 7 to clean the sidewall of the middle section of the conical container 3.

[0042] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sidewall cleaning device 7 includes a primary drive mechanism 71, a secondary drive mechanism 72, and a cleaning mechanism 73. The cleaning mechanism 73 includes a wall-scraping slider 731 and a wall-scraping mechanism 732. A wall-scraping sliding groove 31 is provided on the sidewall of the conical container 3. The wall-scraping slider 731 is slidably connected in the wall-scraping sliding groove 31. A shaking mechanism 74 is provided on the wall-scraping slider 731. The wall-scraping mechanism 732 is installed on the shaking mechanism 74. The wall-scraping slider 731 is driven by the secondary drive mechanism 72, which is driven by the primary drive mechanism 71. The primary drive mechanism 71 is connected to the diverter impeller 6.

[0043] During the process of the side wall cleaning device 7 cleaning the side wall of the conical container 3, the diverter impeller 6 drives the primary drive mechanism 71 to operate, the primary drive mechanism 71 drives the secondary drive mechanism 72 to operate, and the secondary drive mechanism 72 drives the scraping slider 731 to reciprocate along the side wall of the conical container 3. The scraping mechanism 732 on the scraping slider 731 will clean the side wall of the conical container 3.

[0044] Third embodiment: as follows Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the primary drive mechanism 71 includes a main drive bevel gear 711, a secondary drive bevel gear 712, a first drive roller 713, a first drive belt 714, and a driven roller 715. The main drive bevel gear 711 is coaxially arranged with the overflow pipe 5. The main drive bevel gear 711 wraps around the outside of the diverter blade 61 and is fixedly connected to the diverter blade 61. A gear meshing groove 32 is provided on the side of the conical container 3. The toothed end of the main drive bevel gear 711 extends into the gear meshing groove 32. The edge of the main drive bevel gear 711... A secondary drive bevel gear 712 is engaged with the conical container 3. The secondary drive bevel gear 712 is rotatably connected to the side wall of the conical container 3. A first drive roller 713 is coaxially fixedly connected to the secondary drive bevel gear 712. A receiving groove 33 is provided on the side wall of the conical container 3 in a direction parallel to the side wall of the conical container 3, corresponding to the secondary drive bevel gear 712. The receiving groove 33 communicates with the wall scraping sliding groove 31. A driven roller 715 is also provided at the lower end of the secondary drive bevel gear 712 in the receiving groove 33. The first drive roller 713 and the driven roller 715 are connected by a first drive belt 714.

[0045] During the operation of the first drive device, the diverter impeller 6 drives the main drive bevel gear 711 to rotate, the main drive bevel gear 711 drives the secondary drive bevel gear 712 to rotate, and the secondary drive bevel gear drives the first drive roller 713 fixedly connected to it to rotate. The first drive roller 713 drives the driven roller 715 to rotate through the first drive belt 714.

[0046] Fourth embodiment: as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the secondary drive mechanism 72 includes a second drive roller 721 and a second drive belt 722. The second drive roller 721 is disposed in the receiving groove 33. Two second drive rollers 721 are arranged vertically. The upper second drive roller 721 is coaxially and fixedly connected to the driven roller 715, and the two second drive rollers 721 are rotatably connected to the side wall of the conical container 3. The two second drive rollers 721 are connected by the second drive belt 722. The second drive belt 722 is provided with a cylindrical protrusion. A reciprocating rod 7311 is fixedly connected to the wall scraping slider 731. The reciprocating rod 7311 is provided with a first reciprocating groove 7312. The first reciprocating groove 7312 is slidably connected to the cylindrical protrusion on the second drive belt 722.

[0047] The first drive roller 713 located below will drive the second drive roller 721 fixedly connected to it to rotate. The second drive roller 721 will drive the second drive belt 722 to rotate. The cylindrical protrusion on the second drive belt 722 will slide to connect with the first reciprocating groove 7312, thereby causing the reciprocating rod 7311 to drive the scraping slider 731 to reciprocate. In this way, the scraping mechanism 732 on the scraping slider 731 will repeatedly clean the side wall of the conical container 3.

[0048] Fifth embodiment: as follows Figure 7 , Figure 8 and Figure 9 As shown, the shaking mechanism 74 includes a shaking roller 741, a shaking slider 742, and a shaking rod 743. The wall-scraping slider 742 has a roller mounting groove 7313 opened laterally. The shaking roller 741 is rotatably connected to both sides of the roller mounting groove 7313. A shaking groove 7314 is opened on one end of the wall-scraping slider 731 near the central axis of the conical container 3, perpendicular to the roller mounting groove 7313. The shaking groove 7314 communicates with the roller mounting groove 7313. The shaking slider 742 is slidably connected in the shaking groove 7314. The shaking rod 743 is fixedly installed on the shaking slider 742 through the shaking groove 7314. A second reciprocating groove 7431 is opened on the shaking rod 743. A protrusion is installed on the shaking roller 741 near the edge. The second reciprocating groove 7431 is slidably connected to the protrusion on the shaking roller 741.

[0049] As the scraping slider 731 slides along the scraping sliding groove 31, the vibrating roller 741 will roll into contact with the scraping sliding groove 31, thus generating rolling. At this time, the protrusion on the vibrating roller 741 will slide into connection with the second reciprocating groove 7431, thereby driving the vibrating rod 743 and the vibrating slider 742 to reciprocate. The vibrating slider 742 will drive the scraping mechanism 732 on it to vibrate, thereby improving the cleaning effect on the side wall of the conical container 3.

[0050] Sixth embodiment: as follows Figure 7 , Figure 8 and Figure 9 As shown, the wall scraping mechanism 732 includes a wall scraping spring 7321, a wall scraping rubber strip 7322, and a locking block 7323. The locking block 7323 is fixedly installed on the shaking slider 742. The wall scraping spring 7321 is fixedly installed on both sides of the shaking slider 742 in the horizontal opposite direction. The wall scraping rubber strip 7322 is fixedly installed at one end of the wall scraping spring 7321 near the side wall of the conical container 3.

[0051] Because the radius of the conical container 3's cross-section changes during the movement of the scraping mechanism 732 along the side wall of the conical container 3, the scraping spring strip 7321, made of elastic metal, presses the scraping rubber strip 7322 against the side wall of the conical container 3. Simultaneously, it can bend accordingly based on the change in the diameter of the conical container 3's cross-section, thereby improving the adhesion between the scraping rubber strip 7322 and the side of the conical container 3, thus enhancing the cleaning effect on the side wall of the conical container 3. Figure 7 As shown, the scraping strip 7322 has multiple grooves opened horizontally along its upper edge, which can further increase the friction between the scraping strip 7322 and the side wall of the conical container 3, thereby improving the cleaning effect.

[0052] Seventh embodiment: as follows Figure 7 and Figure 8 As shown, the snap-fit ​​block 7323 is installed on the vibrating slider 742 by snap-fit. The vibrating slider 742 has a snap-fit ​​groove 7421. The snap-fit ​​block 7323 has a spring mounting groove 7324 in the middle. A snap-fit ​​rod 7325 is slidably connected to both the upper and lower ends of the spring mounting groove 7324. A snap-fit ​​spring 7326 is fixedly connected between the two snap-fit ​​rods 7325. The vibrating slider 742 has a slot corresponding to the snap-fit ​​rod 7325. The snap-fit ​​rod 7325 is snapped into the slot.

[0053] When the scraping rubber strip 7322 ages, the locking rod 7325 can be pressed down, so that the scraping mechanism 732 can be quickly removed for easy inspection and replacement.

[0054] Eighth embodiment: as follows Figure 5 and Figure 6 As shown, the upper and lower sides of the wall scraping sliding groove 31 on the conical container 3 are provided with sealing grooves 34, and the upper and lower sides of the wall scraping slider 731 are fixedly installed with sealing strips 35, which are slidably connected in the sealing grooves 34.

[0055] This prevents mud and sand from entering the receiving trough 33 and affecting the operation of the mechanism during the cleaning of the side wall of the conical container 3.

[0056] The working principle of this invention is as follows: During the wastewater filtration process, turbid water, under external pressure, enters the shell along the tangent of the column through the feed pipe 2. It rotates within the shell, and impurities in the turbid water are drawn to the periphery of the rotating flow due to the significant centrifugal force. The water then flows downwards and is eventually discharged from the bottom sand drain. The water at the center of the rotation flows out through the overflow pipe 5. During this process, the water impacts the diverting blades 61, causing the diverting impeller 6 to rotate. The diverting impeller 6 drives the sidewall cleaning device 7 to clean the sidewall of the middle section of the conical container 3. While the sidewall cleaning device 7 is cleaning the sidewall of the conical container 3, the diverting impeller 6 drives the primary drive mechanism 71, which in turn drives the secondary drive mechanism 72. The secondary drive mechanism 72 then drives the scraping slider 731 to reciprocate along the sidewall of the conical container 3, scraping... The wall-scraping mechanism 732 on the wall slider 731 cleans the sidewall of the conical container 3. During the operation of the first drive device, the diverter impeller 6 drives the main drive bevel gear 711 to rotate. The main drive bevel gear 711 drives the driven bevel gear to rotate, which in turn drives the first drive roller 713 fixedly connected to it to rotate. This first drive roller 713 drives another first drive roller 713 to rotate via the first drive belt 714. The lower first drive roller 713 drives the second drive roller 721 fixedly connected to it to rotate, and the second drive roller 721 drives the second drive belt 714 to rotate. 22 rotates, and the cylindrical protrusion on the second drive belt 722 slides into the first reciprocating groove 7312, causing the reciprocating rod 7311 to drive the scraping slider 731 to reciprocate. This causes the scraping mechanism 732 on the scraping slider 731 to repeatedly clean the sidewall of the conical container 3. As the scraping slider 731 slides along the scraping groove 31, the vibrating roller 741 rolls into contact with the scraping groove 31, causing it to roll. At this time, the protrusion on the vibrating roller 741 slides into the second reciprocating groove 7431, causing the vibrating rod 743 and the vibrating slider 742 to reciprocate, vibrating... The slider 742 causes the scraping mechanism 732 on it to vibrate, thereby improving the cleaning effect on the side wall of the conical container 3. Because the radius of the conical container 3's cross-section changes as the scraping mechanism 732 moves along the side wall, the scraping spring 7321, made of elastic metal, presses the scraping strip 7322 against the side wall of the conical container 3. Simultaneously, it bends according to the change in the diameter of the conical container 3's cross-section, thereby improving the adhesion between the scraping strip 7322 and the side of the conical container 3, thus enhancing the cleaning effect on the side wall of the conical container 3. Figure 7As shown, the scraping strip 7322 has multiple grooves opened horizontally along its upper edge, which can further increase the friction between the scraping strip 7322 and the side wall of the conical container 3, thereby improving the cleaning effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
