Description

Technical Field

[0001] The invention relates to the technical field of oil wastewater treatment equipment, in particular to an oil wastewater treatment device for highly antistatic stable spandex spinning oil. Background Art

[0002] Spandex is the abbreviation of polyurethane fiber, which is an elastic fiber. Spandex is generally composed of multiple filaments, generally 10D / filament, and now there are 15D / filament, or even 20D / filament. The fewer the theoretical number of filaments, the better the uniformity of the yarn, because the chance of overlapping morphology is less. The production solution DMAC of dry spinning is harmful to the human liver. Generally, 10D / filament contains 0.5mg / kg, such as 15D / filament, which exceeds the standard. When producing spandex, special attention should be paid to the winding tension, the number of counts on the drum, the breaking strength, the breaking elongation, the degree of formation, the amount of oil adhesion, the elastic recovery rate, etc. These problems directly affect the weaving, especially the knitting production of single-sided fabrics. The oil used in the spandex spinning process will produce wastewater after production. These wastewaters often contain a large amount of oil components, chemical additives and other pollutants, which need to be reasonably treated before they can be discharged or recycled.

[0003] Existing oil wastewater treatment devices usually put oil wastewater and wastewater treatment agents into the device for full reaction, and then remove the flocculated impurities generated by the reaction. However, the filter net of the existing oil wastewater treatment device is difficult to filter the flocculated impurities for a long time. After filtering for a period of time, the filter net needs to be cleaned, which greatly reduces the efficiency of wastewater treatment. Summary of the invention

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The water purification mechanism includes a driving motor fixedly connected to the central axis at the top of the water purification box, the output end of the driving motor is fixedly connected to the output shaft, the middle of the output shaft is fixedly connected to a plurality of fixed blocks, the side walls of the fixed blocks are rotatably connected to a plurality of rotating shafts, and the middle of the rotating shaft is transmission-connected to a screening conveyor belt.

[0008] Furthermore, a screening auxiliary mechanism is arranged inside the water purification tank, and the screening auxiliary mechanism includes a plurality of gear rings fixedly connected to the inner wall of the water purification tank, and a gear is fixedly connected to one end of the rotating shaft away from the fixed block, and the gear is meshed with the gear ring.

[0009] Furthermore, a filtering mechanism is arranged on the side wall of the water purification tank body, and the filtering mechanism includes a plurality of water purification ports opened on the side wall of the water purification tank body, and a clean water cavity is formed between the inner wall of the equipment shell and the outer wall of the water purification tank body.

[0010] Furthermore, the filtering mechanism also includes a sliding screen plate slidably connected in the water purification port, and an inclined chamfer is provided on one side of the sliding screen plate close to the output shaft, and a plurality of screen holes are opened on one side of the sliding screen plate close to the output shaft.

[0011] Furthermore, an auxiliary filtering mechanism is arranged on the rotating shaft, and the auxiliary filtering mechanism includes a fixed plate rotatably connected to one end of the rotating shaft away from the fixed block, the fixed plate is rotatably connected to a rotating column on the side away from the screening conveyor belt, both ends of the rotating column are fixedly connected to extrusion rollers, and the middle part of the rotating column is fixedly connected to a cleaning sponge.

[0012] Furthermore, the auxiliary filtering mechanism also includes a plurality of telescopic rods fixedly connected to the inner wall of the device housing, one end of the telescopic rod away from the inner wall of the device housing is fixedly connected to the sliding screen plate, and one end of the telescopic rod close to the sliding screen plate is sleeved with a return spring.

[0013] Furthermore, a cleaning mechanism is arranged inside the clean water tank, and the cleaning mechanism comprises a plurality of protective covers fixedly connected to the side walls of the fixed blocks, and a scraper is fixedly connected to the bottom of the protective covers, and the scraper is in close contact with the surface of the screening conveyor belt.

[0014] Furthermore, the cleaning mechanism also includes a collecting box fixedly connected to the side of the scraper away from the screening conveyor belt, the end of the collecting box away from the output shaft is in contact with the interior of the clean water tank body, the side wall of the clean water tank body is provided with a discharge outlet, the side wall of the clean water tank body is fixedly connected to a material guide plate, and the side wall of the equipment housing is fixedly connected to a storage box.

[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, when the oily wastewater treatment device is used, the wastewater pipe is first connected to the water inlet, and an appropriate amount of wastewater treatment agent is added into the clean water tank. Then, the drain pipe is connected to the clean water drain outlet, and the drive motor is started. The output end of the drive motor rotates to drive the fixed block on the output shaft to rotate. The fixed block rotates to drive the screening conveyor belt on the rotating shaft to rotate around the output shaft. This arrangement is conducive to the screening conveyor belt to fully stir the oily wastewater and the wastewater treatment agent in the clean water tank so that they fully react and flocculate into blocks. On the other hand, the screening conveyor belt can filter the flocculated blocks in the wastewater and attach them to the surface of the screening conveyor belt.

[0017] (2) The present invention sets a screening auxiliary mechanism. The output end of the driving motor rotates to drive the fixed block on the output shaft to rotate. The fixed block rotates to drive the gear at one end of the rotating shaft to rotate. Since the gear ring is meshed with the gear, the gear drives the rotating shaft to rotate. The rotating shaft rotates to drive the screening conveyor belt to rotate. At this time, the rotation of the screening conveyor belt can make the side of the screening conveyor belt that is not attached to the flocculants rotate to the filtering surface, thereby improving the collection efficiency of the flocculants by the screening conveyor belt.

[0018] (3) The present invention sets a filtering mechanism, and the water inside the clean water tank enters the clean water chamber through the sieve holes on the sliding sieve plate. The clean water inside the clean water chamber is then discharged through the clean water drain port. At the same time, the waste water flocs inside the clean water tank are filtered by the sieve holes and attached to the inner wall of the sliding sieve plate. When the rotating shaft rotates and drives the fixed plate to rotate, the fixed plate drives the extrusion roller on the rotating column to rotate around the output rotating shaft. When the extrusion roller is squeezed by the chamfered surface of one side of the sliding sieve plate, the sliding sieve plate squeezes the telescopic rod. At this time, the sliding sieve plate moves rapidly toward one side of the clean water chamber. At this time, under the impact of the reaction force of the clean water inside the clean water chamber, the clean water flushes the flocs attached to the inner wall of the sliding sieve plate and moves them to the inside of the clean water tank. This arrangement can prevent the sieve holes on the sliding sieve plate from being blocked on the one hand, and is conducive to the rapid collection of flocs inside the clean water tank on the other hand.

[0019] (4) The present invention provides a cleaning mechanism. When the rotating shaft rotates and drives the screening conveyor belt to rotate, the rotation of the screening conveyor belt drives the floccules attached to the surface of the screening conveyor belt to move upward. At this time, the scraper scrapes the floccules on the surface of the screening conveyor belt into the collection box. When the collection box rotates to the vicinity of the discharge outlet, under the action of centrifugal force, the flocculated impurities inside the collection box are thrown out of the clean water tank through the discharge outlet, and the flocculated impurities fall into the storage box through the guide plate. This arrangement is conducive to continuously cleaning the flocculated impurities on the screening conveyor belt, thereby improving the filtering efficiency of the screening conveyor belt. By providing a protective cover, the wastewater falling from the water inlet is prevented from flushing the floccules on the screening conveyor belt into the wastewater inside the clean water tank again.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The function of this component is to set the screening auxiliary mechanism 3 so that the output end of the driving motor 201 rotates to drive the fixed block 203 on the output rotating shaft 202 to rotate. The fixed block 203 rotates to drive the gear 302 at one end of the rotating shaft 204 to rotate. Since the toothed ring 301 is meshed with the gear 302, the gear 302 drives the rotating shaft 204 to rotate. The rotating shaft 204 rotates to drive the screening conveyor belt 205 to rotate. At this time, the rotation of the screening conveyor belt 205 can rotate the side of the screening conveyor belt 205 that is not attached to the flocculants to the filtering surface, thereby improving the collection efficiency of the screening conveyor belt 205 for the flocculants.

[0039] Example 2

[0040] like Figure 1-Figure 9 As shown, the present invention is an oil wastewater treatment device for a highly antistatic and stable spandex spinning oil. On the basis of Example 1, an auxiliary filtering mechanism 5 is arranged on the rotating shaft 204, and the auxiliary filtering mechanism 5 includes a fixed plate 501 rotatably connected to the end of the rotating shaft 204 away from the fixed block 203, and the fixed plate 501 is rotatably connected to a rotating column 502 on the side away from the screening conveyor belt 205, and both ends of the rotating column 502 are fixedly connected to extrusion rollers 503, and the middle part of the rotating column 502 is fixedly connected to a cleaning sponge 504.

[0041] The auxiliary filtering mechanism 5 also includes a plurality of telescopic rods 505 fixedly connected to the inner wall of the device housing 1. The end of the telescopic rod 505 away from the inner wall of the device housing 1 is fixedly connected to the sliding screen plate 403. The end of the telescopic rod 505 close to the sliding screen plate 403 is sleeved with a reset spring 506. The function of this component is that when the rotating shaft 204 rotates to drive the fixed plate 501 to rotate, the fixed plate 501 drives the extruding roller 503 on the rotating column 502 to rotate around the output rotating shaft 202. When the extruding roller 503 is in contact with the sliding screen plate 403, the reset spring 506 is provided. When the chamfers on one side of the movable sieve plate 403 are squeezed, the sliding sieve plate 403 squeezes the telescopic rod 505. At this time, the sliding sieve plate 403 quickly moves to the side of the clean water chamber 401. At this time, under the impact of the reaction force of the clean water inside the clean water chamber 401, the clean water flushes the flocculants attached to the inner wall of the sliding sieve plate 403 and moves them to the inside of the clean water tank 12. This arrangement, on the one hand, avoids the blockage of the sieve holes 404 on the sliding sieve plate 403, and on the other hand, is conducive to the rapid collection of flocculants inside the clean water tank 12.

[0042] A cleaning mechanism 6 is provided inside the clean water tank 12 , and the cleaning mechanism 6 includes a plurality of protective covers 601 fixedly connected to the side wall of the fixed block 203 , and a scraper 602 is fixedly connected to the bottom of the protective cover 601 , and the scraper 602 is in close contact with the surface of the screening conveyor belt 205 .

[0043] The cleaning mechanism 6 also includes a collecting box 603 fixedly connected to the side of the scraper 602 away from the screening conveyor belt 205. The end of the collecting box 603 away from the output shaft 202 is in contact with the inside of the clean water tank 12. The side wall of the clean water tank 12 is provided with a discharge outlet 604. The side wall of the clean water tank 12 is fixedly connected with a guide plate 605. The side wall of the equipment housing 1 is fixedly connected with a storage box 606. The function of this component is to set the cleaning mechanism 6. When the rotating shaft 204 rotates and drives the screening conveyor belt 205 to rotate, the screening conveyor belt 205 rotates and drives the flocculants attached to the surface of the screening conveyor belt 205 to move upward. At this time, the scraper 602 will The flocculated impurities on the surface of the screening conveyor belt 205 are scraped off into the collecting box 603. When the collecting box 603 rotates to the vicinity of the discharge outlet 604, the flocculated impurities inside the collecting box 603 are thrown out of the clean water tank 12 through the discharge outlet 604 under the action of centrifugal force, and the flocculated impurities fall into the storage box 606 through the guide plate 605. This arrangement is conducive to continuously cleaning the flocculated impurities on the screening conveyor belt 205, thereby improving the filtration efficiency of the screening conveyor belt 205. By setting a protective cover 601, the wastewater falling from the water inlet 13 is prevented from flushing the flocculated impurities on the screening conveyor belt 205 into the wastewater inside the clean water tank 12 again.

[0044] A specific application of this embodiment is:

This arrangement is conducive to the screening conveyor belt 205 to fully stir the oil wastewater and the wastewater treatment agent in the clean water tank 12 to fully react and flocculate into blocks, and on the other hand, the screening conveyor belt 205 can The flocculants in the wastewater are filtered and attached to the surface of the screening conveyor belt 205; by setting the screening auxiliary mechanism 3, the output end of the driving motor 201 rotates to drive the fixed block 203 on the output shaft 202 to rotate, and the fixed block 203 rotates to drive the gear 302 at one end of the rotating shaft 204 to rotate. Since the gear ring 301 is meshed with the gear 302, the gear 302 drives the rotating shaft 204 to rotate, and the rotating shaft 204 rotates to drive the screening conveyor belt 205 to rotate. At this time, the rotation of the screening conveyor belt 205 can make the side of the screening conveyor belt 205 that is not attached to the flocculants rotate to the filtering surface, thereby improving the collection efficiency of the screening conveyor belt 205 for the flocculants.

[0046] By setting the filtering mechanism 4, the water inside the clean water box 12 enters the clean water chamber 401 through the sieve hole 404 on the sliding sieve plate 403, and the clean water inside the clean water chamber 401 is discharged through the clean water drain port 14. At the same time, the waste water flocs inside the clean water box 12 are filtered by the sieve hole 404 and attached to the inner wall of the sliding sieve plate 403. When the rotating shaft 204 rotates to drive the fixed plate 501 to rotate, the fixed plate 501 drives the extrusion roller 503 on the rotating column 502 to rotate around the output shaft 204. When the shaft 202 rotates, when the squeezing roller 503 is squeezed with the chamfered surface of one side of the sliding screen plate 403, the sliding screen plate 403 squeezes the telescopic rod 505, and the sliding screen plate 403 quickly moves to the side of the clean water chamber 401. At this time, under the impact of the reaction force of the clean water inside the clean water chamber 401, the clean water flushes the flocculent blocks attached to the inner wall of the sliding screen plate 403 and moves them to the inside of the clean water tank 12. This arrangement can prevent the sieve holes 404 on the sliding screen plate 403 from being blocked. On the other hand, it is beneficial to quickly collect the flocculated blocks inside the clean water box 12; by setting the cleaning mechanism 6, when the rotating shaft 204 rotates and drives the screening conveyor belt 205 to rotate, the screening conveyor belt 205 rotates and drives the flocculated blocks attached to the surface of the screening conveyor belt 205 to move upward, and at this time, the scraper 602 scrapes the flocculated impurities on the surface of the screening conveyor belt 205 into the collection box 603. When the collection box 603 rotates to the vicinity of the discharge outlet 604, under the action of centrifugal force, the flocculated impurities inside the collection box 603 are thrown out of the clean water box 12 through the discharge outlet 604, and the flocculated impurities fall into the storage box 606 through the guide plate 605. This arrangement is beneficial to continuously cleaning the flocculated impurities on the screening conveyor belt 205, thereby improving the filtration efficiency of the screening conveyor belt 205. By setting the protective cover 601, it is prevented that the wastewater falling from the water inlet 13 will wash the flocculated blocks on the screening conveyor belt 205 into the wastewater inside the clean water box 12 again.
