Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a wastewater separation device. Background Art

[0002] In the printing and dyeing process, a large amount of high-alkalinity wastewater is discharged. By recycling and reusing the alkali solution in the wastewater, production costs can be reduced and energy conservation and emission reduction can be achieved. At present, the device used to separate the alkali solution from the wastewater usually adopts a nanofiltration membrane. The water in the wastewater can pass through the nanofiltration membrane, while the alkali solution cannot pass through the nanofiltration membrane, thereby achieving separation. The separation rate of water and liquid can reach about 50%. In actual applications, the nanofiltration membrane is wrapped around the outer periphery of the tube, and wastewater is passed into the tube. The water can seep out from the nanofiltration membrane on the outer periphery of the tube. When the wastewater flow in the tube is insufficient, resulting in a low internal water pressure, the wastewater does not exert enough pressure on the nanofiltration membrane on the outer periphery of the tube, resulting in low water penetration efficiency and affecting the alkali solution recovery efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, a wastewater separation device is used for separating alkali liquid from water in high-alkalinity industrial wastewater. The wastewater separation device includes a cylinder 1 and a damping assembly 4. The cylinder 1 includes a connecting cylinder 11. The connecting cylinder 11 is a cylindrical cylinder structure. A top cover is provided at the upper end of the connecting cylinder 11, and a bottom cover 13 is provided at the lower end. The top cover at the upper end of the connecting cylinder 11, the connecting cylinder 11, and the bottom cover 13 are coaxially arranged and integrally formed. The outer diameter of the top cover at the upper end of the connecting cylinder 11 and the outer diameter of the bottom cover 13 are both larger than the outer diameter of the connecting cylinder 11. A filter membrane 3 is wound on the outer wall of the connecting tube 11. The filter membrane 3 is wound with multiple layers along the axis of the connecting tube 11 and is sealed with glue on the outermost side to form a cylindrical structure. The upper and lower ends of the filter membrane 3 are respectively connected with the top cover and the bottom cover 13 at the upper end of the connecting tube 11 to form a connection. The filter membrane 3 is a nanofiltration membrane. When industrial wastewater flows through the filter membrane 3, the water in the wastewater can pass through the filter membrane 3 to be filtered out, while the alkali liquid in the wastewater cannot penetrate the filter membrane 3, so that the filter membrane 3 separates the alkali liquid from the water, and the concentration of the alkali liquid in the wastewater increases. The alkali liquid can be recycled and reused to reduce the cost of using the alkali liquid and reduce emission pollution.

[0024] like Figure 1 As shown, the cylinder 1 is axially provided with a main channel 14, the connecting cylinder 11 is coaxial with the main channel 14, the main channel 14 passes through the cylinder 1 up and down and passes through the connecting cylinder 11, the top cover at the upper end of the connecting cylinder 11 and the bottom cover 13 at the lower end of the connecting cylinder 11 are both connected with a connecting pipe 2, and the connecting pipe 2 connected to the top cover at the upper end of the connecting cylinder 11 passes high-alkalinity wastewater, and the high-alkalinity wastewater passes through the main channel 14 and then passes out from the connecting pipe 2 connected to the bottom cover 13.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, a first channel 12 is provided on the outer wall of the connecting cylinder 11, and the first channel 12 penetrates the outer wall of the connecting cylinder 11, and multiple channels are provided along the circumference of the outer wall of the connecting cylinder 11. The length direction of the first channel 12 extends downward along the top cover at the upper end of the connecting cylinder 11 to near the upper end of the bottom cover 13. One end of the first channel 12 is connected to the radial outer side of the main channel 14, and the other end is abutted against the radial inner side of the filter membrane 3. The industrial waste water passing through the main channel 14 can enter the filter membrane 3 along the first channel 12, thereby separating the alkali solution from the water, wherein the alkali solution continues to flow along the main channel 14, and part of the water passes through the filter membrane 3.

[0026] like Figure 2 As shown, the damping assembly 4 is inserted into the bottom of the cylinder 1. Specifically, the damping assembly 4 includes an insert 41 at the bottom, which is threadedly connected and inserted into the bottom of the bottom cover 13. The insert 41 is provided with a third flow channel 411, which axially passes through the insert 41 and is connected to the bottom of the main channel 14, so that the wastewater in the main channel 14 can flow into the connecting pipe 2 below. Figure 4 A plurality of third flow channels 411 are provided along the circumference of the insert tube 41 to increase the flow area.

[0027] like Figure 1 , Figure 2 As shown, the upper end of the insert tube 41 is fixedly connected to a support rod 42, and the support rod 42 includes a main rod 421, a first extension rod 422 located above the main rod 421, and a second extension rod 423 located above the first extension rod 422. The main rod 421, the first extension rod 422, and the second extension rod 423 are all cylindrical structures, and the main rod 421, the first extension rod 422, and the second extension rod 423 are coaxially arranged. The outer diameter of the main rod 421 is smaller than that of the first extension rod 422, and the outer diameter of the first extension rod 422 is smaller than that of the second extension rod 423.

[0028] like Figure 2 As shown, the damping assembly 4 includes a sliding plate 43, which is a disc structure, combined with Figure 3 The sliding plate 43 is provided with a through hole portion 432, and the through hole portion 432 axially penetrates the sliding plate 43 up and down to serve as a circulation channel.

[0029] The sliding plate 43 is slidably connected to the inner wall of the connecting tube 11, and the sliding plate 43 can move up and down along the inner wall of the connecting tube 11. Specifically, an extension portion 431 is provided on the outer wall of the sliding plate 43, and the extension portion 431 extends radially outward along the outer wall of the sliding plate 43. A plurality of extension portions 431 are evenly distributed along the circumferential direction of the outer wall of the sliding plate 43. The extension portions 431 are arranged one-to-one correspondingly to the first channels 12, and the extension portions 431 are inserted into the first channels 12. The outer wall of the sliding plate 43 abuts against the connecting tube 11. The sliding plate 43 divides the main channel 14 into the first main channel 141 and the second main channel 142 located below the first main channel 141. The sliding plate 43 is located above the insert tube 41, so the third flow channel 411 is actually connected to the second main channel 142.

[0030] like Figure 2 As shown, the bottom of the sliding plate 43 abuts against a spring 44 , and the bottom of the spring 44 abuts against the upper end of the insert tube 41 .

[0031] like Figure 2 As shown, the damping assembly 4 also includes a support rod 42, which passes through the through hole portion 432. The outer diameter of the first extension rod 422 matches the aperture of the through hole portion 432. In the initial state, the sliding plate 43 is located at the upper limit position, and the upper end surface of the sliding plate 43 abuts against the lower end surface of the second extension rod 423, so that the first main channel 141 and the second main channel 142 are separated from each other up and down. The wastewater in the first main channel 141 cannot directly flow downward into the second main channel 142 along the axial direction. At this time, the wastewater flow in the first main channel 141 is small, and the sliding plate 43, the support rod 42 and the connecting tube 11 form a barrier to the wastewater in the first main channel 141, so that the wastewater in the first main channel 141 gradually gathers, thereby increasing the pressure of the wastewater in the first main channel 141 on the filter membrane 3, which is beneficial for the water in the wastewater to pass through the filter membrane 3, thereby improving the separation effect of the alkali solution and the water solution.

[0032] When the amount of wastewater in the first main channel 141 increases and the water pressure increases, the sliding plate 43 moves downward under the action of the water pressure and leaves the bottom of the first extension rod 422. Figure 5 , Figure 6 At this time, the main rod 421 passes through the through hole 432. Since the outer diameter of the main rod 421 is smaller than the through hole 432, the wastewater in the first main channel 141 flows into the second main channel 142 along the through hole 432, and the first main channel 141 and the second main channel 142 are connected. When the wastewater pressure in the first main channel 141 is insufficient, the sliding plate 43 moves upward and blocks the wastewater in the first main channel 141 again.

[0033] like Figure 1 , Figure 2 As shown, after the water in the wastewater passes through the filter membrane 3, it flows downward and is discharged from the second channel 131 of the bottom cover 13. The second channel 131 is not connected to the connecting pipe 2 connected to the bottom cover 13. The wastewater flowing out from the connecting pipe 2 connected to the bottom cover 13 contains a large amount of alkali solution for recovery.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
