Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for epoxy resin production. Background Technology

[0002] Epoxy resin is a widely used thermosetting resin material. Its production process generates wastewater, which contains high levels of salt and complex organic matter and requires special treatment.

[0003] The treatment process involves adding flocculants. The traditional method involves mixing the flocculant with the wastewater according to a specified ratio in a mixing tank and stirring to induce flocculation and sedimentation. After stirring, the mixture is allowed to stand for a period of time, during which time flocculants will form in the wastewater. The mixing tank is equipped with a discharge pipe; once flocculation and sedimentation are complete, the treated wastewater can be discharged by opening the discharge pipe. However, during waste discharge, some flocculants adhere to the bottom wall of the mixing tank, gradually accumulating and forming scale, while other flocculants are discharged with the wastewater, affecting subsequent wastewater treatment. Summary of the Invention

[0004] In view of the above problems, the present invention provides a wastewater treatment device for epoxy resin production.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wastewater treatment device for epoxy resin production is provided, including a mixing tank. A first injection pipe for injecting wastewater and a second injection pipe for injecting flocculant are provided on the side wall of the mixing tank. A drain pipe is connected to the side wall of the mixing tank below the first injection pipe. Valves are provided on the first injection pipe, the second injection pipe, and the drain pipe. A first filter screen for filtering flocculants is provided at the inlet end of the drain pipe. An installation plate is vertically slidably mounted inside the mixing tank. A turntable is rotatably mounted on the installation plate. A first stirring paddle is provided on the turntable. A discharge port is provided at the bottom of the mixing tank, and a receiving mechanism for collecting flocculants is provided at the discharge port. Multiple first scraper blades are provided at the bottom of the first stirring paddle for scraping flocculants from the bottom wall of the mixing tank and guiding the flocculants into the discharge port. A first driving component is provided on the mixing tank for moving the installation plate. The turntable is rotatably mounted on the installation plate via a first linkage assembly.

[0006] Furthermore, the first linkage component includes a rotating rod with an irregular cross-section, and a mounting hole with a size adapted to the rotating rod is provided at the axis of the turntable. The rotating rod is rotatably disposed inside the mixing tank, and a second driving component is provided on the top of the mixing tank for driving the rotating rod to rotate.

[0007] Furthermore, each blade of the first stirring paddle is linearly slidably equipped with a second scraper. The second scraper is equipped with an adjusting component for adjusting its own moving distance. The adjusting component includes a screw. One end of the screw is rotatably connected to the blade of the first stirring paddle, and the other end of the screw is threadedly connected to the second scraper. The blade of the first stirring paddle is equipped with a first guide rod parallel to the moving direction of the corresponding second scraper. The side of the second scraper away from the side wall of the mixing tank is provided with a guide groove adapted to the first guide rod. The mixing tank is equipped with a second linkage assembly for driving multiple screws to rotate synchronously.

[0008] Furthermore, the second linkage component includes an annular boss coaxially fixed on the top wall of the mixing tank. A friction pad is provided at the bottom of the annular boss. A transmission wheel for pressing against the friction pad is coaxially fixed on the outer wall of multiple screws. When the mounting plate moves up and the multiple transmission wheels press against the friction pad, the turntable rotates and the multiple transmission wheels can roll circumferentially along the annular boss to drive the multiple screws to rotate synchronously.

[0009] Furthermore, the bottom of at least one second scraper extends into the inner side of the first agitator, so that the scraping range of the plurality of second scrapers and the plurality of first scrapers can cooperate to cover the inner bottom wall of the mixing tank.

[0010] Furthermore, multiple second stirring paddles are spaced apart along the circumference of the mounting plate. Each second stirring paddle is rotatably connected to the side wall of the mounting plate via a transmission assembly. The transmission assembly includes a gear disk and multiple gears. The multiple gears are respectively fixed on the rotating shaft of each second stirring paddle. The gear disk is coaxially fixed on the turntable and meshes with each gear.

[0011] Furthermore, the receiving mechanism includes a receiving box located below the discharge port. The receiving box contains two filtration zones, each containing a second filter screen. A waste discharge port for discharging flocculants is located on the side wall of the filtration zone at the second filter screen, and a cover is provided at the waste discharge port. A baffle for switching between opening and closing the two filtration zones is rotatably installed below the discharge port inside the receiving box. A third driving component for driving the baffle to rotate is provided on the outside of the receiving box. A return pipe is provided at the bottom of the filtration zone, with one end of the return pipe extending into the mixing tank. A circulation pump is provided on the return pipe.

[0012] Furthermore, the cover plate is rotatably installed at the waste discharge port, with the pivot of the cover plate located at the top of the waste discharge port. The side of the cover plate used to close the waste discharge port is provided with a sealing gasket for pressing against the outer wall of the receiving box opening. The cover plate is also provided with a door lock for connecting the receiving box.

[0013] Furthermore, it also includes a cleaning mechanism for cleaning the inside of the mixing tank. The cleaning mechanism includes multiple nozzles, which are spaced apart on the top of the mixing tank. One end of each nozzle extends into the mixing tank and is provided with multiple discharge ports. The other end of each nozzle is connected to a supply device for supplying cleaning fluid.

[0014] Furthermore, an ultrasonic cleaner is installed on the side wall of the mixing tank.

[0015] The beneficial effects of this invention are as follows: the vertical reciprocating movement of the mounting plate and the rotation of the turntable allow the first stirring paddle to move vertically and stir the wastewater and flocculant; after stirring is completed, the mounting plate and the turntable stop moving, and the wastewater in the mixing tank can be allowed to settle and produce flocculants. Then, the mounting plate moves vertically downward and the first scraper blade can contact the bottom wall of the mixing tank. The rotation of the turntable scrapes the settled flocculants into the discharge port and into the receiving mechanism; after the flocculants are treated, the wastewater in the mixing tank can be discharged through the drain pipe for the next batch of wastewater treatment; during the discharge process, the first filter screen can prevent residual flocculants from entering the drain pipe. This not only prevents flocculants from accumulating and forming scale on the bottom wall of the mixing tank, but also prevents flocculants from being discharged through the drain pipe, thus improving the wastewater treatment effect.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This application discloses a wastewater treatment device for epoxy resin production, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mixing tank 1. A first injection pipe 11 for injecting wastewater and a second injection pipe 12 for injecting flocculant are installed on the side wall of the mixing tank 1. A drain pipe 13 is connected to the side wall of the mixing tank 1 below the first injection pipe 11. Valves (not shown in the figure) are installed on the first injection pipe 11, the second injection pipe 12, and the drain pipe 13. A first filter screen 131 for filtering flocculants is installed at the inlet end of the drain pipe 13. A mounting plate 2 is vertically slidably installed inside the mixing tank 1. A turntable 3 is rotatably installed on the mounting plate 2, and a first stirring paddle 4 is installed on the turntable 3. A discharge port 14 is provided at the bottom of the mixing tank 1, and a receiving mechanism 5 for collecting flocculants is provided at the discharge port 14. Multiple first scraper blades 6 are provided at the bottom of the first stirring paddle 4 for scraping flocculants on the bottom wall of the mixing tank 1 and guiding the flocculants into the discharge port 14. The mixing tank 1 is provided with a first driving component 7 for driving the mounting plate 2 to move, and the turntable 3 is rotatably mounted on the mounting plate 2 through the first linkage component.

[0025] In this embodiment, wastewater to be treated can be injected into the mixing tank 1 through the first injection pipe 11, and flocculant can be injected into the mixing tank 1 through the second injection pipe 12. Then, the mounting plate 2 moves vertically back and forth, and the turntable 3 rotates, allowing the first stirring paddle 4 to move vertically and stir the wastewater and flocculant. After stirring is complete, the mounting plate 2 and the turntable 3 stop moving, and the wastewater in the mixing tank 1 can be allowed to settle and produce flocculants. Then, the mounting plate 2 moves vertically downwards, allowing the first scraper 6 to contact the bottom wall of the mixing tank 1. The turntable 3 rotates, scraping the settled flocculants into the discharge port 14 and into the receiving mechanism 5. After the flocculants are treated, the wastewater in the mixing tank 1 can be discharged through the drain pipe 13 for the next batch of wastewater to be treated. During the discharge process, the first filter screen 131 prevents residual flocculants from entering the drain pipe 13. This wastewater treatment device for epoxy resin production can be used to collect flocculants from wastewater. This not only prevents flocculents from accumulating and forming scale on the bottom wall of the mixing tank 1, but also prevents flocculents from being discharged through the drain pipe 13, thus improving the wastewater treatment effect.

[0026] The first driving component 7 includes two driving cylinders, which are vertically mounted on the top of the mixing tank 1. The piston rods of the driving cylinders extend into the mixing tank 1 and are bolted to the mounting plate 2. The mounting plate 2 is also provided with a second guide rod 21 parallel to the moving direction of the mounting plate 2, and one end of the second guide rod 21 moves through the top of the mixing tank 1.

[0027] Reference Figure 4 The first linkage component includes a rotating rod 8 with an irregular cross-section. The rotating disk 3 has a mounting hole 31 with a size that matches the rotating rod 8 at its axis. The rotating rod 8 is rotatably installed inside the mixing tank 1. The top of the mixing tank 1 is provided with a second driving component 81 for driving the rotating rod 8 to rotate.

[0028] In this embodiment, the second driving member 81 drives the rotating rod 8 to rotate, thereby enabling the turntable 3 to rotate synchronously. During the vertical movement of the mounting plate 2, the turntable 3 can also move along the axial direction of the rotating rod 8.

[0029] The second driving component 81 includes a first driving motor, which is disposed on the top of the mixing tank 1, and the output shaft of the first driving motor is connected to the rotating rod 8 for transmission.

[0030] Reference Figure 5Each blade of the first stirring paddle 4 is linearly slidably equipped with a second scraper 9, and each second scraper 9 is equipped with an adjusting component 10 for adjusting its own moving distance. The adjusting component 10 includes a screw 101, one end of which is rotatably connected to the blade of the first stirring paddle 4, and the other end of which is threadedly connected to the second scraper 9. The blade of the first stirring paddle 4 is equipped with a first guide rod 102 parallel to the moving direction of the corresponding second scraper 9. The side of the second scraper 9 away from the side wall of the mixing tank 1 has a guide groove adapted to the first guide rod 102. The mixing tank 1 is equipped with a second linkage assembly for driving the multiple screws 101 to rotate synchronously.

[0031] In this embodiment, some of the flocculants generated in the wastewater easily adhere to the inner wall of the mixing tank 1. Multiple screws 101 can be rotated simultaneously via the second linkage assembly to drive multiple second scraper blades 9 to move synchronously. After flocculants are generated, the multiple second scraper blades 9 can move and contact the inner wall of the mixing tank 1. The rotation of the first stirring paddle 4 allows the second scraper blades 9 to scrape off the flocculants on the inner wall of the mixing tank 1, thereby improving the treatment effect on the flocculants. After scraping is completed, the multiple second scraper blades 9 need to move away from the inner wall of the mixing tank 1.

[0032] Specifically, the second linkage component includes an annular boss 20 coaxially welded to the top wall of the mixing tank 1. A friction pad 201 is bolted to the bottom of the annular boss 20, and multiple screws 101 have drive wheels 1011 coaxially welded to their outer walls for pressing against the friction pad 201. When the mounting plate 2 moves upward and the multiple drive wheels 1011 press against the friction pad 201, the turntable 3 rotates, causing the multiple drive wheels 1011 to roll circumferentially along the annular boss 20 to drive the multiple screws 101 to rotate synchronously.

[0033] In this embodiment, the mounting plate 2 moves upward and the transmission wheels 1011 on the multiple screws 101 can press against the contact friction pad 201. Then the turntable 3 rotates, so that the multiple screws 101 can rotate synchronously to drive the multiple second scraper blades 9 to move synchronously.

[0034] In order to improve the scraping effect on the flocculent material on the inner bottom wall of the mixing tank 1, at least one second scraper 9 extends to the inner side of the first agitator 4, so that the scraping range of the multiple second scraper 9 and the multiple first scraper 6 can cover the inner bottom wall of the mixing tank 1.

[0035] Furthermore, a plurality of second stirring paddles 30 are spaced apart along their circumference on the mounting plate 2, and each second stirring paddle 30 is rotatably connected to the side wall of the mounting plate 2 via a transmission assembly 40. The transmission assembly 40 includes a gear disk 401 and a plurality of gears 402, which are respectively welded and fixed to the rotating shaft of each second stirring paddle 30, and the gear disk 401 is coaxially fixed on the turntable 3 and meshes with each gear 402.

[0036] As the turntable 3 rotates and causes the first stirring paddle 4 to rotate, stirring the wastewater, the gear disc 401 rotates synchronously to drive each gear 402 to rotate synchronously. By coordinating the rotation of the first stirring paddle and multiple second stirring paddles 30, the stirring effect on the wastewater can be improved.

[0037] Reference Figure 6 The receiving mechanism 5 includes a receiving box 51 located below the discharge port 14, and two filtration zones are provided inside the receiving box 51. A second filter screen 52 is provided in each filtration zone, and a waste discharge port 511 for discharging flocculants is provided on the side wall of the filtration zone at the second filter screen 52, with a cover plate 53 provided at the waste discharge port 511. A baffle 54 for switching the opening and closing of the two filtration zones is rotatably installed inside the receiving box 51 below the discharge port 14, and a third driving component for driving the baffle 54 to rotate is provided on the outside of the receiving box 51. A return pipe 55 is provided at the bottom of the filtration zones, one end of which extends into the mixing tank 1, and a circulation pump 56 is installed on the return pipe 55.

[0038] In this embodiment, a third driving component can drive a baffle 54 to rotate and block one of the filtration zones, while a second filter screen 52 in the other filtration zone is used to filter and collect flocculants falling into the discharge port 14. Through a corresponding circulating pump 56 and return pipe 55, wastewater at the bottom of the mixing tank 1 can be pumped out and discharged back into the mixing tank 1, further improving the mixing efficiency of the wastewater.

[0039] After a period of time, when flocculent material accumulates in one of the filtration zones, the baffle 54 can be rotated to switch to the other filtration zone. At this time, the corresponding circulation pump 56 can pump the wastewater in the blocked filtration zone into the mixing tank 1. Then, the corresponding cover 53 can be opened to discharge the flocculent material accumulated on the second filter screen 52. By switching between the two filtration zones in this way, the device can discharge some of the accumulated flocculent material without stopping the wastewater treatment process, thus improving the wastewater treatment efficiency.

[0040] The third driving component includes a second driving motor, which is mounted on the outer wall of the receiving box 51, and the output shaft of the second driving motor is connected to the rotating shaft of the baffle 54.

[0041] Specifically, the cover plate 53 is rotatably installed at the waste discharge port 511, the pivot of the cover plate 53 is located at the top of the waste discharge port 511, and a sealing gasket 57 is provided on one side of the cover plate 53 for sealing the waste discharge port 511 for pressing against the outer wall of the opening of the receiving box 51. A door lock 58 for connecting the receiving box 51 is provided on the cover plate 53.

[0042] In this embodiment, the sealing gasket 57 is made of rubber. The door lock 58 includes a knob and a latch. The inner wall of the receiving box 51 has a slot that matches the latch. Rotating the knob will drive the latch to rotate and move in and out of the slot, thereby allowing the cover plate 53 to open and close the waste discharge port 511.

[0043] Furthermore, it also includes a cleaning mechanism 50 for cleaning the inside of the mixing tank 1. The cleaning mechanism 50 includes a plurality of nozzles 501, which are spaced apart on the top of the mixing tank 1. One end of each nozzle 501 extends into the mixing tank 1 and is provided with a plurality of discharge ports. The other end of each nozzle 501 is externally connected to a supply device for supplying cleaning fluid.

[0044] In this embodiment of the application, cleaning fluid can be sprayed into the mixing tank 1 through multiple nozzles 501 to rinse the inner wall of the mixing tank 1 and the various components inside the mixing tank 1.

[0045] During the rinsing process, the cleaning fluid can be drawn out by the circulation pump 56 and injected back into the mixing tank 1, which in turn helps to flush the various components inside the mixing tank 1, further improving the cleaning effect on the inside of the mixing tank 1. After the level of the cleaning fluid has submerged the first stirring paddle 4 and the multiple second stirring paddles 30, the first stirring paddle 4 and the multiple second stirring paddles 30 can work together to stir and clean the inside of the mixing tank 1.

[0046] To improve the cleaning effect inside the mixing tank 1, an ultrasonic cleaner 60 is installed on the side wall of the mixing tank 1.

[0047] The implementation principle of a wastewater treatment device for epoxy resin production according to an embodiment of this application is as follows: The mounting plate 2 moves vertically back and forth, and the turntable 3 rotates, allowing the first stirring paddle 4 to move vertically and mix the wastewater and flocculant. After mixing, the mounting plate 2 and turntable 3 stop moving, allowing the wastewater in the mixing tank 1 to settle and produce flocculants. Then, the mounting plate 2 moves vertically downwards, allowing the first scraper 6 to contact the bottom wall of the mixing tank 1. The turntable 3 rotates, scraping the settled flocculants into the discharge port 14 and into the receiving mechanism 5. After the flocculants are treated, the wastewater in the mixing tank 1 can be discharged through the drain pipe 13 for the next batch of wastewater treatment. During the discharge process, the first filter screen 131 prevents residual flocculants from entering the drain pipe 13. This not only prevents flocculants from accumulating and forming scale on the bottom wall of the mixing tank 1 but also prevents flocculants from being discharged through the drain pipe 13, thus improving the wastewater treatment effect.
