Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment devices, specifically a wastewater treatment device for producing iron oxide yellow. Background Technology

[0002] Iron oxide yellow's main component is iron oxide, which is a monohydrate of iron oxide. The biggest application of iron oxide is as a pigment.

A gear is fixedly connected to the outer surface of the round shaft, and the outer surface of the gear meshes with the outer surface of the toothed plate.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention, by setting up a first valve, a separation tank, a dewatering tank, and a perforated plate, allows operators to add flocculants and other chemical materials into the wastewater inside the reaction tank through a feeding pipe. After sedimentation and reaction, the iron oxide yellow particles can aggregate together. Then, by starting the drive motor, the rotating shaft drives the rotating rod to rotate, which in turn causes the hinge rod to move the connecting block and the perforated plate to the right. This allows the perforated plate to push the aggregated iron oxide yellow particles into the separation tank. At this point, by activating the first valve, the wastewater inside the reaction tank can be discharged through the first valve. Then, by activating the second valve, the iron oxide yellow and wastewater inside the separation tank can fall into the dewatering tank through the second valve. The wastewater will fall through the filter plate, thus separating the iron oxide yellow from the wastewater, facilitating recycling by the operator.

[0023] 2. This invention, by setting up a lifting plate, stirring blades, a power motor, and a push-pull rod, allows the operator to start the stirring motor after adding flocculant into the reaction tank. This causes the stirring rod to rotate the stirring blades, thus stirring the wastewater and allowing the chemical reaction to proceed more fully. The operator can also start the power motor to move the moving block to the left, which in turn causes the push-pull rod to move the lifting plate upward, which in turn causes the stirring motor to move upward. This allows the stirring blades to move upward to above the partition, thus preventing the stirring blades from interfering with the movement of the perforated plate.

[0024] 3. This invention, by setting up a pressure plate, a toothed plate, a fixed motor, and gears, allows the operator to start the fixed motor, causing the round shaft to drive the gears to rotate. This, in turn, causes the gears to drive the two toothed plates to move in opposite directions, which in turn causes the fixed plate to drive the connecting rod to move in opposite directions. This allows the two pressure plates to move in opposite directions, enabling the pressure plates to squeeze and dehydrate the iron oxide yellow microparticle polymer, thus facilitating collection and subsequent processing by the operator.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, an embodiment of the present invention provides a wastewater treatment device for the production of iron oxide yellow, comprising:

[0035] The reaction chamber 1 has an inlet 2 fixedly sleeved on the back, a feeding pipe 3 fixedly sleeved on the right side, a first valve 4 fixedly sleeved on the bottom, a filter screen 5 fixedly sleeved on the top of the inner surface of the first valve 4, a separation box 6 fixedly installed on the right side of the bottom of the reaction chamber 1, a second valve 7 fixedly sleeved on the inside of the bottom end of the separation box 6, and a dehydration box 8 fixedly sleeved on the bottom of the second valve 7.

[0036] A separation mechanism is located inside reaction chamber 1.

[0037] The drive mechanism is located at the top of the reaction chamber 1;

[0038] The separation mechanism includes two limiting rods 9. The left and right ends of the two limiting rods 9 are fixedly connected to the left and right sides of the inner surface of the reaction chamber 1, respectively. A mesh plate 10 is movably sleeved on the left side of the outer surface of the limiting rod 9. A connecting block 11 is fixedly connected to the rear side of the top of the mesh plate 10. The outer surface of the connecting block 11 is movably connected to the inner wall of the reaction chamber 1. The limiting rods 9 limit the mesh plate 10.

[0039] The operator discharges wastewater into the reaction tank 1 through inlet 2, and then adds flocculant and other chemical materials into the reaction tank 1 through feed pipe 3, so that the iron oxide yellow particles inside the reaction tank 1 can aggregate together. Then, by moving the connecting block 11 to the right, the mesh plate 10 pushes the aggregated iron oxide yellow inside the reaction tank 1 to the top of the separation tank 6. By activating the first valve 4, the wastewater inside the reaction tank 1 can be discharged through the first valve 4.

[0040] The drive mechanism includes:

[0041] Drive motor 12 is fixedly installed on the rear side of the top of reaction chamber 1, and the other end of the output shaft of drive motor 12 is fixedly connected to rotating shaft 13;

[0042] The rotating rod 14 has its right end fixedly sleeved to the outer surface of the rotating shaft 13. The left end of the rotating rod 14 is hinged to a hinge rod 15, and the left end of the hinge rod 15 is hinged to the top of the connecting block 11.

[0043] The operator starts the drive motor 12, which causes the rotating shaft 13 to drive the rotating rod 14 to rotate, thereby causing the hinge rod 15 to pull the connecting block 11 to move to the right.

[0044] The reaction chamber 1 is fixedly installed with a partition 16 inside, and a circular sleeve 17 is fixedly fitted inside the top of the reaction chamber 1.

[0045] By setting up a partition 16, the space inside the reaction chamber 1 can be divided.

[0046] A vertical rod 18 is fixedly installed on the front side of the top of the reaction chamber 1. A lifting plate 19 is movably sleeved on the outer surface of the vertical rod 18. A stirring motor 20 is fixedly installed on the top of the lifting plate 19. A stirring rod 21 is fixedly connected to the other end of the output shaft of the stirring motor 20. The bottom end of the stirring rod 21 passes through the lifting plate 19 and the circular sleeve 17 and extends into the interior of the reaction chamber 1, and is movably sleeved with the inner walls of the lifting plate 19 and the circular sleeve 17 respectively. A stirring blade 22 is fixedly connected to the bottom of the outer surface of the stirring rod 21.

[0047] The operator can start the stirring motor 20, which causes the stirring rod 21 to drive the stirring blade 22 to rotate, thereby stirring the wastewater and allowing the chemical reaction to proceed more fully.

[0048] Among them, a fixing block 23 is fixedly installed on the right side of the top of the reaction box 1, and a power motor 24 located below the lifting plate 19 is fixedly installed on the top of the reaction box 1. The other end of the output shaft of the power motor 24 is fixedly connected to a threaded rod 25, and the outer surface of the threaded rod 25 is movably sleeved with the inner wall of the fixing block 23.

[0049] The operator can start the power motor 24 to make the threaded rod 25 rotate.

[0050] Among them, a movable block 26 is threadedly sleeved on the right side of the outer surface of the threaded rod 25. The bottom of the movable block 26 is movably connected to the top of the reaction chamber 1. A push-pull rod 27 is hinged inside the top of the movable block 26. The top of the push-pull rod 27 is hinged to the bottom of the lifting plate 19.

[0051] When the moving block 26 moves to the left, it will cause the push-pull rod 27 to push the lifting plate 19 upward.

[0052] The bottom of the inner cavity of the dehydration tank 8 is fixedly installed with a filter plate 28, and a sealing door 29 is hinged to the right side of the dehydration tank 8.

[0053] By setting up a filter plate 28, the liquid can fall through the filter plate 28, while the iron oxide yellow particles can remain on the upper surface of the filter plate 28.

[0054] The bottom of the dehydration tank 8 is fixedly fitted with a first water pipe 30, and the outer surface of the first water pipe 30 is fixedly connected with a second water pipe 31. The top end of the second water pipe 31 is fixedly connected to the bottom of the first valve 4.

[0055] By setting up the first water pipe 30, the wastewater from which iron oxide has been separated can be collected together for further treatment.

[0056] The dehydration tank 8 has pressure plates 32 installed on both the front and rear sides. The bottom of the pressure plates 32 is movably connected to the top of the filter plate 28. A connecting rod 33 is fixedly connected to the outside of the pressure plates 32. The other end of the connecting rod 33 passes through the dehydration tank 8 and extends to the outside of the dehydration tank 8 and is movably connected to the inner wall of the dehydration tank 8. A fixing plate 34 is fixedly connected to the outer end of the connecting rod 33. A toothed plate 35 is fixedly connected to the outer surface of the fixing plate 34.

[0057] When the two toothed plates 35 move toward each other, the fixed plate 34 will drive the two connecting rods 33 to move toward each other, thereby enabling the two pressure plates 32 to move toward each other, thus squeezing and dehydrating the iron oxide precipitate.

[0058] Among them, a fixed motor 36 is fixedly installed on the left side of the dehydration tank 8, and a round shaft 37 is fixedly connected to the other end of the output shaft of the fixed motor 36. A gear 38 is fixedly connected to the outer surface of the round shaft 37, and the outer surface of the gear 38 meshes with the outer surface of the toothed plate 35.

[0059] When gear 38 rotates, it will cause the two tooth plates 35 to move in opposite directions.

[0060] Working principle and usage process:

[0061] The operator discharges wastewater into the reaction tank 1 through inlet 2, and then feeds flocculant and other chemical materials into the wastewater through feed pipe 3. Then, by starting the stirring motor 20, the stirring rod 21 drives the stirring blade 22 to rotate, thereby stirring the wastewater and making the wastewater react more fully with the flocculant and chemical materials. Then, by starting the power motor 24, the threaded rod 25 drives the moving block 26 to move to the left, and the push-pull rod 27 pushes the lifting plate 19 to rise along the outer surface of the vertical rod 18, so that the stirring blade 22 can move upward to above the partition 16.

[0062] After the chemical reaction inside the reaction chamber 1 is completed, the operator can start the drive motor 12, which causes the rotating shaft 13 to drive the rotating rod 14 to rotate. This causes the hinge rod 15 to drive the connecting block 11 and the mesh plate 10 to move to the right. As a result, the mesh plate 10 can push the aggregated iron oxide yellow particles to the right into the separation chamber 6. Then, by starting the first valve 4, the wastewater inside the reaction chamber 1 can be discharged through the first valve 4. Then, by starting the second valve 7, the wastewater and iron oxide yellow particles inside the separation chamber 6 can fall into the dehydration chamber 8, thereby completing the separation of iron oxide yellow from the wastewater.

[0063] After the wastewater and iron oxide yellow fall into the dewatering tank 8, the wastewater will enter the first water pipe 30 through the filter plate 28. At this time, the operator can start the fixed motor 36, so that the round shaft 37 drives the gear 38 to rotate, which in turn drives the two toothed plates 35 to move in opposite directions. This causes the toothed plates 35 to drive the connecting rod 33 to move in opposite directions through the fixed plate 34, so that the two pressure plates 32 can squeeze and dewater the iron oxide yellow microparticle polymer on the upper surface of the filter plate 28, which facilitates the operator's collection and treatment.
