Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to degreasing water treatment equipment and a treatment method thereof. Background Art

[0002] During the industrial wastewater treatment process, industrial wastewater contains not only some heavy metal elements and particles, but also some oils and industrial chemical residues. Before the water treatment equipment treats the industrial wastewater, it is necessary to first use a filter device to filter the wastewater to intercept the solid particles and other substances inside it, so as to reach the device with the function of separating pure liquid. The wastewater is then treated through biological, physical, and chemical methods to make it recyclable. Common industrial wastewater treatment is generally done by adding chemicals to the sewage treatment pool to precipitate the suspended matter in the water, and then discharging the purified water to achieve the effect of water recycling.

[0003] However, for the current industrial wastewater treatment process, it is difficult to quickly and effectively separate and collect the oil in it, and the subsequent drug addition and mixing process only uses stirring blades for motor rotation and stirring. The stirring blades themselves are mostly fan-blade structures. The fan-blade structure can only meet the drug mixing needs in the center of the water area. The drug mixing is not uniform enough, making it difficult to achieve further improvement in the sewage treatment process.

[0004] Therefore, we propose a degreasing water treatment device and a treatment method thereof to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology. The present invention provides a degreasing water treatment equipment and treatment method. It can perform a series of steps such as solid particle separation, oil removal and degreasing, and drug addition and disinfection on the wastewater in a step-by-step manner. The drug addition process is mixed by an eccentric universally rotating stirring blade, which ensures more complete drug mixing and significantly improves the process effect.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a degreasing water treatment equipment, comprising:

[0007] A water diversion tank is sequentially provided with a mutually independent solid-liquid separation zone, a dosing zone, and a degreasing zone. The dosing zone is connected to a valve at the bottom of the degreasing zone. A filter is horizontally fixed in the solid-liquid separation zone to separate solid particles. An oil scooping mechanism is fixed on the top of the degreasing zone. The oil scooping mechanism includes a servo-driven oil scooping plate, which is vertically placed and maintains its bottom in contact with the upper oil layer in the degreasing zone. Multiple stirring mechanisms are equidistantly fixed in the dosing zone. Each stirring mechanism includes an adjusting member, a driving member, and a stirring blade. The stirring blade is a circular structure. The driving member is used to drive the stirring blade to swing universally about its center of the circle. The adjusting member is used to eccentrically adjust the stirring blade.

[0008] A multi-stage filtration structure is arranged outside the water diversion tank, comprising at least two bag filters, adjacent bag filters are connected by pipelines, and the bag filter at the last stage is connected to the degreasing area pipeline;

[0009] A water pump has one end connected to the solid-liquid separation zone pipeline and the other end connected to the multi-stage filter pipeline.

[0010] Furthermore, the oil skimming mechanism also includes a mounting plate, a reduction motor, an electric control box, an oil scraper and an oil collecting trough. The mounting plate is bolted to the outer edge of the top of the degreasing area, and a motor isolation cover is fixed to its inner end, and the outer end is welded and fixed to the oil collecting trough. The center of the oil skimming plate is connected to the inner wall bearing of the motor isolation cover through a rotating shaft and keeps the bottom end exposed to the motor isolation cover. The reduction motor is fixedly connected to the outer side of the motor isolation cover, and its output end is coaxially fixed to the rotating shaft. The oil scraper includes two symmetrically arranged on both sides of the oil scraper. Each of the oil scrapers has a triangular outer edge protruding from the top of one end close to the oil scraper, and the outer edge is in friction contact with the surface of the oil scraper.

[0011] Furthermore, an angle groove is fixed at the bottom of the oil scraper plate, and the angle groove is fixed at an angle to the inner wall of the motor isolation cover, with an inclination angle of 30° to 60°. One end of the bottom of the angle groove overlaps with the oil receiving groove, and a slot is passed through the center of the top end for the oil skimmer plate to rotate.

[0012] Furthermore, the electric control box is electrically connected to the reduction motor and is integrated with a control panel for adjusting the speed of the reduction motor.

[0013] Furthermore, a plurality of horizontal plates are fixed on the top of the dosing area, and an adjusting piece is fixed on each horizontal plate at equal intervals through a vertical plate.

[0014] Furthermore, each of the adjusting parts includes a rotating platform, a screw rod, a nut seat, a limit plate, a push plate and a swing plate. The rotating platform includes two and is symmetrically fixed to the upper and lower ends of the vertical plate. The screw rod is rotatably connected to the two rotating platforms. A limit slot is provided in the center of the limit plate. The top of the nut seat is slidably connected to the limit slot, and its bottom is threadedly engaged with the screw rod. One end of the push plate is hinged to the top of the nut seat through a first hinge leaf, and the other end is hinged to the back of the swing plate through a second hinge leaf. The bottom end of the swing plate is hinged to the bottom end of the limit plate through a third hinge leaf. The vertical plate is exposed on the top shaft section of the screw rod and an adjustment handle is coaxially fixed thereto.

[0015] Furthermore, the driving member includes a swing shaft, a motor fixing platform, an eccentric plate, a roller, a support rod and a limit platform. The swing shaft is rotatably connected to the motor fixing platform, one end of which is driven to rotate by the motor, and the other end is connected and fixed to the eccentric plate. The end of the eccentric plate away from the swing shaft is bent and set and vertically fixed to the support rod. The roller is rollingly connected to the other end of the support rod, and the stirring blade is rotatably connected to the outer wall of the roller and limited by the limit platform.

[0016] Furthermore, the limit platform includes two conical panels symmetrical with the center of the roller, and the two conical panels are connected as a whole through a connecting plate. The top center of each conical panel is hollowed out and is rollingly connected to the roller. The stirring blade is grooved and inserted at the corresponding connecting plate to limit the position. The outer side of the conical panel close to the eccentric plate is connected and fixed to the motor fixing platform through an extension plate. The stirring blade is exposed outside the conical panel and is always kept apart from the dosing area during the swinging process.

[0017] Furthermore, the bag filter is of WS model series and is a single bag type with a single bag size of ф219x410mm and a flow rate of 10-20m 3 / h, working pressure is 1.5bar.

[0018] The water treatment method for the above-mentioned degreasing water treatment equipment comprises the following steps:

[0019] S1. Sewage enters the pool and is first separated by a static separation in the solid-liquid separation area to achieve solid-liquid separation. A filter is installed simultaneously to prevent floating particles from rising again. After the stratification is completed, the upper layer of liquid is pumped by a water pump and sequentially passed through multiple bag filters for adsorption filtration. The flow rate in the pipeline is controlled at 10-20m 3 / h, working pressure is 1.5bar;

[0020] S2. After the bag filter is finished filtering, it is sent to the degreasing area for a second static period until the oil floats up and separates. The speed of the oil skimmer is adjusted by the electric control box to correspond to the height of the separation layer. The oil skimmer then absorbs the upper layer of oil and simultaneously scrapes it off through the scraper and drops it tiltedly into the oil receiving tank.

[0021] S3. After degreasing, the valve is opened to allow the lower layer of water in the degreasing area to enter the dosing area, and inorganic flocculants and disinfectants are added simultaneously. Then, multiple stirring mechanisms are used to stir and mix. During the stirring process, the stirring blades can be eccentrically adjusted by the driving parts and the adjusting parts to ensure sufficient mixing.

[0022] Compared with the prior art, the beneficial effects of the present invention include: the sewage after solid-liquid separation can be adsorbed and filtered through two bag filters and sent to the degreasing area for standing, and then adsorbed, scraped and sent out by the oil skimming plate when it rotates, and finally the medicine is added in the dosing area, and universal stirring is performed simultaneously through multiple stirring mechanisms, and the stirring position can be eccentrically adjusted by the corresponding adjusting parts, avoiding the problems of insufficient stirring and insufficient drug mixing uniformity caused by conventional fan-type stirring blades.

[0037] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0038] According to one embodiment of the present invention, Figures 1-6 Shown.

[0039] like Figure 1 As shown, in terms of the overall structure, in this embodiment, a degreasing water treatment device includes:

[0040] A water diversion tank 1 is provided with a mutually independent solid-liquid separation zone 12, a dosing zone 13, and a degreasing zone 14, the dosing zone 13 being connected to a valve at the bottom of the degreasing zone 14. A filter is fixed horizontally in the solid-liquid separation zone 12 to separate solid particles. An oil scooping mechanism 2 is fixed on the top of the degreasing zone 14. The oil scooping mechanism 2 includes a servo-driven rotating oil scooping plate 201. The oil scooping plate 201 is placed vertically and maintains its bottom in contact with the upper oil layer in the degreasing zone 14. A plurality of stirring mechanisms 3 are fixed equidistantly in the dosing zone 13. Each stirring mechanism 3 includes an adjusting member 31, a driving member 32, and a stirring blade 33. The stirring blade 33 is a circular structure. The driving member 32 is used to drive the stirring blade 33 to swing universally about its center of the circle. The adjusting member 31 is used to eccentrically adjust the stirring blade 33.

[0041] A multi-stage filtration structure 4 is provided outside the water diversion tank 1 and includes at least two bag filters 41. Adjacent bag filters 41 are connected by pipes, and the bag filter 41 at the last stage is connected by a pipe to the degreasing area 14.

[0042] The water pump 5 has one end connected to the pipeline of the solid-liquid separation zone 12 and the other end connected to the pipeline of the multi-stage filter.

[0043] Through the above structure, the filter can be made of stainless steel to prevent the suspended particles in the solid-liquid separation area 12 from floating up again. The sewage is then adsorbed and filtered through two bag filters 41 and sent to the degreasing area 14 for standing. It is then adsorbed, scraped and sent out by the oil skimming plate 201 during rotation. Finally, drugs are added in the dosing area 13, and universal stirring is performed simultaneously through multiple stirring mechanisms 3. The stirring position can be eccentrically adjusted by the corresponding adjustment member 31, avoiding the problems of insufficient stirring and insufficient drug mixing uniformity caused by the conventional fan-type stirring blades 33.

[0044] like Figure 4 As shown, the oil scooping mechanism 2 also includes a mounting plate 202, a reduction motor 203, an electric control box 204, an oil scraper 205 and an oil collecting trough 206. The mounting plate 202 is bolted to the outer edge 208 of the top of the degreasing area 14, and a motor isolation cover is fixed to its inner end, and the outer end is welded and fixed to the oil collecting trough 206. The center of the oil scooping plate 201 is connected to the inner wall bearing of the motor isolation cover through a rotating shaft 207 and keeps the bottom end exposed to the motor isolation cover. The reduction motor 203 is fixedly connected to the outside of the motor isolation cover, and its output end is coaxially fixed with the rotating shaft 207. The oil scraper 205 includes two and symmetrically arranged on both sides of the oil scraper 201. Each of the oil scrapers 205 has a triangular outer edge 208 protruding from the top of one end close to the oil scraper 201, and the outer edge 208 is in friction contact with the surface of the oil scraper 205.

[0045] Furthermore, an angled slot 209 is fixed to the bottom of the oil scraper 205. The angled slot 209 is fixed to the inner wall of the motor isolation cover at an angle of 30° to 60°. One end of the bottom of the angled slot 209 overlaps the oil receiving groove 206, and a slot 210 is formed through the center of the top end to allow the oil skimmer 201 to rotate. The electrical control box 204 is electrically connected to the reduction motor 203 and is integrated with a control panel to adjust the speed of the reduction motor 203.

[0046] The inclined scraper plate 205 can firstly allow the scraped grease to fall by gravity for collection, and secondly, can maximize the contact length between the scraper plate 205 and the oil collecting plate 201 to improve the degreasing efficiency.

[0047] like Figure 1-Figure 3 As shown, a plurality of horizontal plates 34 are fixed on the top of the dosing area 13, and an adjusting member 31 is fixed to each horizontal plate 34 at equal intervals through a vertical plate 35. There are many options for the adjusting member 31 and the driving member 32. In this embodiment, the specific structure is as follows.

[0048] like Figure 5 When the cam 330 is in the unlocked position, the locking cam 330 is locked and the locking cam 331 is in the unlocked position, and the winch 330 is locked.

[0049] After manually turning the adjustment handle 330, the screw rod 312 can be positioned and rotated in the rotating table 311, and then the nut seat 313 that is threadedly matched with it can be shifted up and down under the limiting action of the limiting groove 317, synchronously driving the hinged push plate 315 to shift. Due to the hinged action of the second hinge leaf 319 and the third hinge leaf 320, the displacement of the push plate 315 can be converted into a support for the back of the swing plate 316, thereby realizing the adjustment effect of the swing plate within a certain angle range, which is convenient for the subsequent eccentric adjustment of the stirring blade 33.

[0050] Furthermore, the driving member 32 includes a swing shaft 321, a motor fixing platform 322, an eccentric plate 323, a roller 324, a support rod 325 and a limit platform 326. The swing shaft 321 is rotatably connected to the motor fixing platform 322, one end of which is driven to rotate by the motor, and the other end is connected and fixed to the eccentric plate 323. The end of the eccentric plate away from the swing shaft 321 is bent and set and vertically fixed to the support rod 325. The roller 324 is rollingly connected to the other end of the support rod 325. The stirring blade 33 is rotatably connected to the outer wall of the roller 324 and is limited by the limit platform 326.

[0051] After the swing shaft 321 is driven to rotate by an external motor (not shown in the figure), it can drive the roller 324 to rotate under the action of the eccentric plate 323, and the upper and lower ends of the roller 324 are limited by the limiting platform 326, and can swing in all directions in the water. The swing amplitude is more sufficient than that of the existing fan-type stirring blade 33, which can ensure the drug mixing effect of every sewage in the dosing area 13.

[0052] like Figure 6 As shown, the limiting platform 326 includes two conical panels 327 symmetrical with the center of the roller 324, and the two conical panels 327 are connected as a whole through a connecting plate 328. The top center of each conical panel 327 is hollowed out and is rollingly connected to the roller 324. The stirring blade 33 is grooved 210 at the corresponding connecting plate 328 and inserted to limit the position. The outer side of the conical panel 327 close to the eccentric plate 323 is connected and fixed to the motor fixing platform 322 through an extension plate 329. The stirring blade 33 is exposed outside the conical panel 327 and is always kept at a distance from the dosing area 13 during the swinging process.

[0053] Through the above structure, after the roller 324 rotates, it is clamped and limited by the top of the two conical panels 327, and can swing along the connecting plate 328. During the swinging process, the stirring blade 33360° rotates up and down, and after the subsequent adjustment part 31 is adjusted synchronously, the mixing effect is better.

[0054] Furthermore, the bag filter 41 is of WS model series and is a single bag type, with a single bag size of ф219x410mm and a flow rate of 10-20m 3 / h, working pressure is 1.5bar.

[0055] Similarly, the water treatment method applied to the above-mentioned degreasing water treatment equipment is also within the scope of protection of the present invention, and the corresponding treatment steps are as follows:

[0056] S1, sewage enters the pool, first in the solid-liquid separation area 12 static separation to achieve solid-liquid separation, the simultaneous installation of the filter to prevent floating particles from rising again, after the stratification is completed, the upper layer of liquid is pumped by the water pump 5, and then passed through multiple bag filters 41 for adsorption filtration, the pipeline flow rate is controlled at 10-20m 3 / h, working pressure is 1.5bar;

[0057] S2: After the bag filter 41 has finished filtering, the oil is sent to the degreasing area 14 for a second static period until the oil floats up and separates. The electric control box 204 adjusts the speed of the oil skimmer 201 to correspond to the height of the separation layer. The oil skimmer 201 then absorbs the upper layer of oil, which is simultaneously scraped off by the scraper and tilted down into the oil receiving tank 206.

[0058] S3. After degreasing is completed, the valve is opened to allow the lower layer of water in the degreasing area 14 to enter the dosing area 13, and inorganic flocculants and disinfectants are added simultaneously. Then, multiple stirring mechanisms 3 are used to stir and mix. During the stirring process, the driving member 32 and the adjusting member 31 can eccentrically adjust the stirring blade 33 to ensure sufficient mixing.

[0059] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
