Description

Technical Field

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

[0002] The production of water-reducing agents generates a large amount of wastewater containing complex chemical components. If discharged directly without effective treatment, this will not only cause serious pollution to the ecological environment but may also affect the physicochemical properties of surrounding water bodies and soil, as well as biodiversity. Therefore, efficient treatment of wastewater from water-reducing agent production is a crucial step in achieving green production and environmental protection. Currently, flocculation and sedimentation is one of the commonly used methods for treating this type of wastewater due to its simple operation and relatively low cost.

[0003] However, existing technologies have significant drawbacks in practical applications. Traditional flocculant application methods often involve directly sprinkling the flocculant into wastewater ditches or treatment ponds. Due to the complex flow patterns of wastewater, the flocculant struggles to diffuse rapidly and evenly, easily leading to excessively high floc concentrations in some areas, forming large, difficult-to-settle flocs; while in other areas, the concentration is too low, failing to achieve the desired flocculation effect, resulting in poor overall flocculation uniformity. Furthermore, flocculants that have not been pre-dissolved need to gradually dissolve and react in the wastewater, resulting in slow floc formation and poor settling performance, severely impacting wastewater treatment efficiency and quality.

[0004] Based on this, a wastewater treatment device for water-reducing agent production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater treatment device for the production of water-reducing agents in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wastewater treatment device for water-reducing agent production includes a fixed bar, a motor frame connected to the fixed bar, a rotary motor connected to the motor frame, a pinion gear connected to the output end of the rotary motor, a vertical bar connected to the lower end of the fixed bar, a fixed frame connected to the outer side of the vertical bar, a feeding bin connected to one end of the fixed frame, a lower rod and an upper rod slidably connected to one side of the vertical bar, a lifting frame connected to the upper rod and the lower rod, a gate plate connected to one end of the lower rod, a water storage tank connected to the lower end of the lifting frame, a connecting frame connected to the fixed bar, a stirring frame rotatably connected to the connecting frame, and a transmission mechanism connected to the vertical bar for raising the height of the water storage tank.

[0008] Preferably, a groove is provided on the vertical bar, and the upper rod and the lower rod are slidably connected on the groove.

[0009] Preferably, the feeding bin has a gate slot, and the gate is slidably connected to the gate slot.

[0010] Preferably, a deflector plate is rotatably connected to the lower end of the water storage tank, a float is connected to the lower end of the deflector plate, and a sealing strip is connected to the lower end of the water storage tank.

[0011] Preferably, the lower end of the water storage tank is provided with a bottom groove, a deflection rod is connected to the bottom groove, the deflection plate is rotatably connected to the deflection rod, and the sealing strip is disposed between the deflection rods.

[0012] Preferably, the transmission mechanism includes a cam, which is rotatably connected below the fixed bar. A rotating shaft is connected to the cam, and a large gear and a conical wheel are connected to the rotating shaft. The large gear and the small gear mesh with each other. The outer side of the cam is in rolling contact with the lower rod. A vertical rod is rotatably connected to the upper rod and the lower rod. A second conical wheel is connected to the upper end of the vertical rod, and a first conical wheel is connected to the upper end of the stirring frame.

[0013] Preferably, the cam has a groove, and one end of the upper rod is rotatably connected to a limiting wheel, with the limiting wheel in rolling contact with the groove.

[0014] Preferably, a roller is sleeved on the lower rod, and the roller makes rolling contact with the outer surface of the cam.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. This application introduces a portion of the wastewater into a storage tank structure, where flocculants are added and thoroughly mixed within a relatively enclosed and controllable small space. This ensures that the flocculants and wastewater come into full contact, disperse evenly, and complete a relatively thorough flocculation reaction, forming flocs with good settling properties. This mixture is then returned to the ditch, where the water flow helps to evenly distribute the flocculants throughout the wastewater. This effectively avoids the problem of excessively high or low local concentrations of flocculants in the ditch caused by traditional direct addition methods, allowing the flocculation reaction to occur under more uniform conditions, significantly improving the flocculation effect, and more efficiently removing pollutants from the wastewater.

[0017] 2. This application treats a small amount of wastewater extracted within a water storage tank structure, precisely adding flocculant and controlling the reaction time and intensity through stirring and other operations, thus achieving precise control of the flocculation reaction. Compared to the difficulty in accurately controlling the dosage and reaction conditions when directly adding flocculant to large-flow ditch wastewater, this invention effectively ensures the stability and reliability of wastewater treatment results, minimizes interference with the overall water flow in the ditch, reduces floc breakage caused by water flow disturbance, and further improves wastewater treatment efficiency.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a technical solution:

[0027] A wastewater treatment device for water-reducing agent production includes a fixed bar 1, a motor frame 2 connected to the fixed bar 1, a rotary motor 4 connected to the motor frame 2, and the rotary motor 4 fixedly connected to one side of the fixed bar 1 via the motor frame 2. The fixed bar 1 needs to be fixedly connected above a wastewater conveying ditch. A pinion 16 is connected to the output end of the rotary motor 4. A vertical bar 22 is connected to the lower end of the fixed bar 1, and the vertical bar 22 is vertically connected below the fixed bar 1. A fixing frame 11 is connected to the outer side of the vertical bar 22, and a feeding bin 12 is connected to one end of the fixing frame 11. The feeding port of the feeding bin 12 needs to be compatible with the feeding requirements, that is, during the opening time, the feeding amount fluctuates around a certain value. This feeding amount is related to the wastewater volume in the water storage tank 14. The components are matched to achieve proportional mixing of the flocculant liquid. A lower rod 24 and an upper rod 29 are slidably connected to one side of the vertical bar 22. The lower rod 24 is a complete rod structure, while the upper rod 29 is a two-section rod structure. The upper rod 29 and the lower rod 24 are parallel to each other. A lifting frame 13 is connected to the upper rod 29 and the lower rod 24. A gate 23 is connected to one end of the lower rod 24. The gate 23 is vertical. A water storage tank 14 is connected to the lower end of the lifting frame 13. During the lifting and lowering of the water storage tank 14, a certain amount of wastewater can be collected into the water storage tank 14. A connecting frame 3 is connected to the fixed bar 1. A stirring frame 6 is rotatably connected to the connecting frame 3. A transmission mechanism for driving the water storage tank 14 to rise is connected to the vertical bar 22.

[0028] Specifically, such as Figure 3 As shown, a groove 28 is provided on the vertical bar 22, and the upper rod 29 and the lower rod 24 are slidably connected on the groove 28. The upper rod 29 and the lower rod 24 are limited by the groove 28 structure.

[0029] Specifically, such as Figure 3 and Figure 5 As shown, a gate slot 31 is provided on the feeding bin 12, and a gate plate 23 is slidably connected to the gate slot 31. When the gate plate 23 is raised, the discharge port at the lower end of the feeding bin 12 opens, and when the gate plate 23 falls, the discharge port at the lower end of the feeding bin 12 closes.

[0030] Specifically, such as Figure 4 As shown, a deflector plate 18 is rotatably connected to the lower end of the water storage tank 14, and a float 19 is connected to the lower end of the deflector plate 18. A sealing strip 20 is connected to the lower end of the water storage tank 14. When the height of the water storage tank 14 decreases and comes into contact with the wastewater, the wastewater can cooperate with the float 19 to deflect the deflector plate 18. At this time, the wastewater inside the water storage tank 14 can be carried away from the water storage tank 14 by the action of the flowing wastewater, and a new batch of wastewater enters the water storage tank 14. When the height of the water storage tank 14 increases, the deflector plate 18 can close again under the action of gravity. At this time, the joint of the two deflector plates 18 is sealed by the sealing strip 20, so that the lower end of the water storage tank 14 is sealed to prevent the wastewater in the water storage tank 14 from leaking.

[0031] Specifically, such as Figure 4 As shown, a bottom groove 17 is provided at the lower end of the water storage tank 14. A deflection rod 30 is connected to the bottom groove 17. A deflection plate 18 is rotatably connected to the deflection rod 30. A sealing strip 20 is set between the deflection rods 30. A float 19 is connected to one end of the deflection plate 18 near the sealing strip 20, while the other end of the deflection plate 18 is rotatably connected to the deflection rod 30.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the transmission mechanism includes a cam 5, which consists of three parts: one part with a constant radius, one part with an increased radius, and one part with a decreased radius. The increased and decreased radii are collectively referred to as the radius change region, which corresponds to the lifting and lowering process of the water storage tank 14. The cam 5 is rotatably connected to the bottom of the fixed bar 1. A rotating shaft 9 is connected to the cam 5, and a large gear 15 and a conical wheel 10 are connected to the rotating shaft 9. The large gear 15 and the small gear 16 have a certain transmission ratio, so that the rapidly rotating small gear 16 can only drive the large gear 15 to rotate at a low speed. The large gear 15 and the small gear 16 mesh with each other. The outer side of the cam 5 is in rolling contact with the lower rod 24. A vertical rod 25 is rotatably connected to the upper rod 29 and the lower rod 24. A conical wheel 8 is connected to the upper end of the vertical rod 25, and a conical wheel 7 is connected to the upper end of the stirring rack 6. The conical wheel 7, the conical wheel 8, and the conical wheel 10 are transmitted through inclined surface contact. This structure can achieve stable docking and has good transmission stability.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the cam 5 has a wheel groove 21, and one end of the upper rod 29 is rotatably connected to a limiting wheel 27. The limiting wheel 27 and the wheel groove 21 are in rolling contact. Through the contact between the limiting wheel 27 and the wheel groove 21, the cam 5 and the upper rod 29 are kept in a synchronous operating state, ensuring that the roller 26 can rise and fall with the rotation of the cam 5.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a roller 26 is sleeved on the lower rod 24. The roller 26 makes rolling contact with the outer surface of the cam 5. By setting the roller 26, the wear between the lower rod 24 and the cam 5 is reduced, the stability of the transmission is improved, and the rotation of the cam 5 can smoothly drive the water storage tank 14 to move vertically up and down.

[0035] In summary, the wastewater treatment device for water-reducing agent production provided in this embodiment can be installed above the wastewater conveying ditch when it is necessary to treat the wastewater generated during the production process of water-reducing agent. Then, a sufficient amount of flocculant for treating the wastewater is added to the feeding bin 12, and then the rotary motor 4 is started.

[0036] When the rotary motor 4 rotates, it drives the small gear 16 to rotate. Since the small gear 16 meshes with the large gear 15, it drives the large gear 15 to rotate synchronously. Since the large gear 15 is connected to the cam 5 through the rotating shaft 9, the cam 5 can rotate synchronously. When the cam 5 rotates, it relies on the limit wheel 27 to roll on the wheel groove 21, thereby driving the upper rod 29 and the lower rod 24 to perform reciprocating lifting and lowering movements. When the upper rod 29 rises, it can synchronously drive the vertical rod 25 rotatably connected to the upper rod 29 to move upward. At this time, the conical wheel 28 connected to the upper end of the vertical rod 25 moves upward and simultaneously abuts against the conical wheel 3 10 and the conical wheel 1 7. At this time, the cam 5 rotates, which can synchronously drive the conical wheel 3 10, the conical wheel 2 8 and the conical wheel 1 7 to rotate. The stirring rack 6 connected to the lower end of the conical wheel 1 7 begins to rotate.

[0037] When conical wheel 28 contacts conical wheel 17 and conical wheel 30 simultaneously, cam 5 continues to rotate, and upper rod 29 stops moving upward. That is, when conical wheel 28 contacts conical wheel 17, upper rod 29 rises to its maximum height, and limit wheel 27 enters the radius-unchanged region of cam 5. At this time, cam 5 continues to rotate, and conical wheel 28, conical wheel 17 and conical wheel 30 can be in a continuous transmission state.

[0038] When the lower rod 24 rises, it can drive the gate plate 23 to rise, thereby opening the lower end of the feeding bin 12. The flocculant and coagulant inside can fall into the water storage tank 14 below under the action of gravity. At this time, a certain amount of wastewater is placed in the water storage tank 14. With the help of the rotating stirring frame 6, the wastewater treatment material and wastewater can be fully mixed, forming flocs with certain settling properties in the water storage tank 14.

[0039] When the cam 5 rotates to the point where the limit wheel 27 contacts the radius change area of ​​the cam 5, the water storage tank 14 drops in height and sinks into the sewage. The lower end of the feeding bin 12 is closed, and the stirring frame 6 stops rotating. At this time, the float 19 is deflected by the wastewater, causing the deflection plate 18 to deflect, which forces the bottom tank 17 to open. The wastewater that has previously completed the flocculant mixing reaction enters the ditch, and the formed flocs can quickly diffuse in the wastewater, effectively ensuring that the flocculation reaction proceeds evenly and improving the flocculation effect. Since the wastewater in the ditch is in a flowing state, the flocs are put into the wastewater, and at the same time, a new batch of wastewater can rise with the height of the water storage tank 14 and be collected in the water storage tank 14, waiting to react with the flocculant.

[0040] Since the wastewater treatment device is driven by the rotary motor 4, the time for a single lifting and lowering of the water storage tank 14 remains constant, the internal wastewater storage capacity remains constant, and the mass of flocculant added to the feeding bin 12 remains constant. This allows for precise control of the flocculant dosage and reaction conditions. The rotation speed of the rotary motor 4 can be adjusted reasonably according to the wastewater quality, avoiding the direct addition of flocculant to large-flow ditch wastewater. This prevents the difficulty in precisely controlling the water flow rate and the amount of flocculant added, which could result in excessively high or low local concentrations of flocculant at different locations in the wastewater.

[0041] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
