Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and specifically relates to a rapid treatment device for recycling cutting wastewater from steel plate processing. Background Technology

[0002] Cutting fluid is commonly used in machining processes and is mixed with cutting waste. Some machining equipment or factories will treat the cutting waste and waste fluid in a unified manner, while others will treat them separately according to the machining conditions and equipment to ensure that the cutting wastewater can be recycled.

[0003] The typical treatment process for cutting fluid wastewater includes: bar screen filtration, demulsification reaction, and oil-water separation. These are the pretreatment stages. In addition, there are main treatment stages, advanced treatment stages, and reuse treatment stages. Whether it is simple wastewater treatment or purposeful recycling, the pretreatment stage is essential, especially filtration and demulsification, which are particularly important as the foundation for subsequent treatments.

[0004] A search revealed that the prior art publication number CN113336382A provides a cutting fluid wastewater treatment process; the publication number CN119390286A provides another treatment method for a cutting fluid wastewater treatment system for machine tool accessory processing; both emphasize the use of bar screen filtration technology; furthermore, the publication number CN219964083U provides an easy-to-clean cutting fluid wastewater treatment device, which provides a filtration method and addresses filter blockage by using a pin inserted into the filter hole to easily clean the filter residue blocking the filter hole, thereby improving the cleanliness of the filter screen;

[0005] In response to the aforementioned existing technologies, the applicant analyzed and discovered the technical drawbacks when designing the wastewater pretreatment process based on actual conditions. Firstly, there are many types of processing waste, such as chips, powders, strips, and spiral waste, and different processing wastes will form different combinations with the filter plates. Secondly, simply using the ejector pin method cannot guarantee the removal and cleaning of spiral and strip wastes that are easily stuck to the filter plates.

[0006] Therefore, the applicant proposed a wastewater treatment method based on actual improved technology. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid treatment device for recycling cutting wastewater from steel plate processing. This device can not only clamp and remove spiral processing waste connected to the filter plate through a clamping mechanism, but also add demulsifier and extract and transfer floating oil through a demulsification mechanism with a distribution plate. At the same time, the rotation of the distribution plate can also stir the waste water, thereby accelerating the efficiency of demulsification treatment.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0013] The mounting frame has two sets, respectively located on both sides of the treatment tank. Each mounting frame has a mounting block, which is positioned within an installation opening on the side wall of the treatment tank. A sealing plate is fixedly mounted on each mounting block and positioned on one side of the inner wall of the treatment tank to seal the installation opening.

The fixed plate is fixed on the mounting frame; the second electric push rod drives the mounting frame to move up and down in the mounting port so that the material distribution plate can adapt to the depth of the cutting wastewater. Then, the first electric push rod pushes the rack to slide, which in turn drives the main shaft to rotate, thereby causing the two sides of the material distribution plate to rotate and switch, realizing the switching between the spray nozzle and the suction nozzle; the spray nozzle sprays the demulsifier provided by the first box, and the suction nozzle sucks and transfers the oil floating on the water surface to achieve oil-water separation.

[0015] The treatment tank is equipped with a synchronous solenoid valve on its side wall to control the synchronous movement of the second electric push rods on both sides of the treatment tank.

[0016] The cleaning mechanism includes a movable frame and guide rails. The guide rails are located on both sides of the treatment pool.

Each chain plate has a clamping plate at both ends. The clamping plate is located inside the second support plate and has a fixed shaft. The fixed shaft and the deflector shaft are spaced apart. The rubber belt wraps around the chain plate and is fixedly connected. Two sets of clamping mechanisms are configured as a clamping unit. The clamping mechanisms in the clamping unit are close to each other and clamp and pull out the waste material from the filter plate through the rotation effect of adjacent rubber belts. Several sets of clamping units are mounted on the screw, and there is a gap between the clamping units.

[0020] The second support plate is equipped with a support plate to support the rubber belt and prevent foreign objects from entering the rubber belt and affecting the transmission.

[0021] The treatment tank is equipped with a receiving mechanism at one end, including a seventh electric push rod, an arc-shaped arm, and a cover plate. The base of the seventh electric push rod is rotatably connected to a fixed seat on the side wall of the treatment tank. The top shaft of the seventh electric push rod is hinged to one end of the arc-shaped arm, and the other end of the arc-shaped arm is hinged to the cover plate. The two sides of the cover plate are hinged to the treatment tank. The cover plate is rotated by the seventh electric push rod to cover the filter plate on the treatment tank to form a box. The cover plate is equipped with a first locking plate on both sides.

The fifth electric push rod is fixed to the fixed platform, and the top shaft of the fifth electric push rod is provided with a limiting plate. The limiting plate is located in the retaining ring, and the inner diameter of the retaining ring is larger than the outer diameter of the limiting plate, which can provide a certain wobbling gap for the shaft. The fifth electric push rod pushes the shaft to insert into the first and second locking plates.

[0023] The treatment tank is equipped with an observation window at one end, which allows observation of the liquid level inside the tank.

[0024] Preferably, one end of the treatment pool is provided with a support arm to assist in supporting the cover after it is opened.

[0025] A treatment process for recycling cutting wastewater from steel plate processing includes the following steps:

[0026] S1. Wastewater filtration: Preliminary filtration is carried out by using a bar screen and filter plate;

[0027] S2. Demulsification treatment: Additives are added to break down the surfactant layer that encapsulates the oil droplets, causing the tiny oil droplets to aggregate into larger droplets, thereby achieving oil-water separation, facilitating the aggregation of oil, and making subsequent oil suction treatment easier.

[0028] S3, Oil-water separation: The filtered wastewater is separated again by aeration flotation. A large number of microbubbles are generated and attached to the oil droplets, causing them to float to the surface and form a pile of floating oil which is then scraped off.

[0029] S4. Deep filtration: Employs multi-media filters (quartz sand, anthracite, etc.), activated carbon filters, etc.

[0030] S5. Disinfection treatment: Disinfection and odor removal are carried out using conventional water treatment methods to meet discharge standards.

[0031] The advantages of this invention compared to existing technologies are as follows:

[0032] 1) During the cleaning process of the filter plate, the accumulated waste material is first pushed out of the filter plate by the push plate in the top pushing mechanism. When residual processing waste material, such as spiral or strip-shaped material, is stuck to the filter holes on the filter plate, the clamping mechanism in the cleaning mechanism can clamp the waste material and pull it out of the filter holes during the movement. The rubber belt clamps the waste material first during the rotation, and then moves along the filter plate under the drive of the third electric push rod to achieve the pulling effect. After the clamping mechanism moves to the end of the filter plate, the second motor drives the lead screw to rotate and move the clamping unit. During the reset of the top shaft of the third electric push rod, the clamping unit works at the same time. This reciprocating motion completes the processing of residual waste material. Finally, the push plate pushes out the pulled-out waste material. This greatly improves the cleaning effect of the filter plate.

[0033] 2) In the demulsification mechanism, the demulsifier is evenly added through the spray nozzles set on the distribution plate, and the floating oil is sucked and transferred through the suction port that contacts the liquid surface. Furthermore, the mounting frame and the distribution plate can be controlled to move up and down in the mounting port to adapt to the wastewater liquid surface. At the same time, the first electric actuator, in conjunction with gears and racks, drives the main shaft and the distribution plate to rotate, which not only realizes the switching between the spray nozzle and the suction port, but also agitates the wastewater to a certain extent, accelerating the mixing reaction between the demulsifier and the wastewater, providing a basis for other subsequent treatment processes, such as further oil-water separation.

[0080] A treatment process for recycling cutting wastewater from steel plate processing includes the following steps:

[0081] S1. Wastewater filtration: Preliminary filtration is carried out by using a bar screen and filter plate;

[0082] S2. Demulsification treatment: Additives are added to break down the surfactant layer that encapsulates the oil droplets, causing the tiny oil droplets to aggregate into larger droplets, thereby achieving oil-water separation, facilitating the aggregation of oil, and making subsequent oil suction treatment easier.

[0083] S3, Oil-water separation: The filtered wastewater is separated again by aeration flotation. A large number of microbubbles are generated and attached to the oil droplets, causing them to float to the surface and form a pile of floating oil which is then scraped off.

[0084] S4. Deep filtration: Employs multi-media filters (quartz sand, anthracite, etc.), activated carbon filters, etc.

[0085] S5. Disinfection treatment: Disinfection and odor removal are carried out using conventional water treatment methods to meet discharge standards;

[0086] A rapid treatment device for recycling cutting wastewater from steel plate processing, the working process of which is as follows:

[0087] First, the cover plate 53 is rotated and opened by the seventh electric push rod 51 in the receiving mechanism 5. Then, the first motor 308 in the cleaning mechanism 3 drives the moving frame to move along the guide rail 301 to avoid the filter plate 14 being covered, so that the cutting wastewater containing mixed impurities can enter the treatment tank after being filtered by the filter plate 14.

[0088] The filtered waste impurities remain on the filter plate 14, and are then pushed by the sixth electric push rod 42 in the push mechanism 4, and pushed by the push plate 43 to the open cover plate 53, and then transferred by other conventional means. When the push mechanism 4 pushes the impurities, the cover plate 53 is first placed over the filter plate 14, and then the locking mechanism 7 is used to lock the treatment tank 1 and the cover plate 53. Then, the sixth electric push rod 42 pushes the push plate 43 to work with the cover plate 53 to squeeze the waste impurities to achieve solid-liquid separation again. After the squeezing is completed, the cover plate 53 is opened. After the cover plate 53 is opened, the push plate 43 is pushed again to clean the filter plate 14.

[0089] Furthermore, the cutting waste remaining on the filter plate 14, such as waste generated from lathe and drilling machine processing, is relatively long and curved, and can easily get stuck in the filter holes on the filter plate 14. Simply using the push plate 43 to push the material is not easy to clean it. Even the conventional method of using the push rod to push the filter holes is difficult to achieve the desired effect. Therefore, using the clamping mechanism 6 to pull out the processing waste stuck in the filter holes can greatly improve the cleaning effect.

[0090] During cleaning by cleaning mechanism 3, the first motor 308 pushes the moving frame to the top of the filter plate 14; then the fourth electric push rod 315 pushes the fixed frame 314 and the clamping mechanism 6 down to the top of the filter plate 14 and touches the surface of the filter plate 14. Before this, the clamping mechanism 6 is moved to one end of the screw 67, so that the clamping mechanism 6 can move from one side of the filter plate 14 to the other side in turn, avoiding missed areas during cleaning; the third motor 69 is started to drive the roller frame 65 to rotate, and then the deflector 654 on the roller frame 65 deflects the fixed shaft 661 on the chain plate 66, so that the chain plate 66 rotates along the second support plate 64. The cooperation between the clamping plate 662 and the second support plate 64 enables the chain plate 66 to rotate stably, thereby driving the rubber belt 63 to rotate, thus utilizing... Two closely fitting rubber strips 63 clamp the remaining large iron filings, such as the bent cutting material hooked onto the filter plate 14; then, in conjunction with the push of the third electric push rod 310, the clamping mechanism 6 can move forward on the filter plate 14; when the clamping mechanism 6 moves to one end of the filter plate 14, the second motor 62 drives the lead screw 67 to move, so that the clamping unit can move as a whole to the area of ​​the filter plate 14 that has not been clamped and cleaned. Then, the top shaft of the third electric push rod 310 resets, driving the clamping mechanism 6 to move and reset. Correspondingly, the third motor 69 reverses to ensure that the rubber strips 63 can achieve the effect of rotational clamping and continuously clamping and cleaning the waste; according to the above steps, the clamping unit can move back and forth, finally achieving the second cleaning of the filter plate 14. After cleaning is completed, the cleaning mechanism resets.

[0091] For the treatment of the cutting wastewater after filtration in treatment tank 1, demulsification is first performed, and then the floating oil is sucked up to achieve oil-water separation.

[0092] The first electric actuator 25 drives the rack 251 to rotate in conjunction with the gear 2211, which in turn causes the main shaft 221 on the distribution plate 22 to rotate. This allows the spray nozzle 225 to face the liquid surface, and the demulsifier supplied by the water pump in the first housing 27 is sprayed out through the feed pipe 227, connecting pipe 23, hose 201, inlet 224, and spray nozzle 225. Conversely, the retraction of the top shaft of the first electric actuator 25 will cause the distribution plate 22 to rotate, completing the switching and making the suction port 229 face the liquid surface. Then, the liquid can be observed through the observation window 9. The liquid surface is then controlled by the second electric actuator 26 to move the mounting frame 21 and the distribution plate 22 so that the suction port 229 is in contact with the liquid surface. Finally, the water pump in the second tank 28 is used to draw the oil accumulated on the surface of the cutting wastewater to the second tank 28. Before this, the mounting frame 21 can be lowered and the first electric actuator 25 can be used to repeatedly push the rack 251 to move back and forth so that the distribution plate 22 can swing back and forth around the main shaft 221, thereby mixing the demulsifier and wastewater and accelerating the demulsification effect of the demulsifier.

[0093] After the wastewater is treated, it is pumped out through the pumping pipe 12 and the externally connected suction mechanism. Then, the remaining sediment in the treatment tank 1 is opened through the sealing door 11 and cleaned. Conventional cleaning and suction methods are used here, so they will not be described in detail.
