Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, in particular to an industrial wastewater treatment flocculant adding device. Background Art

[0002] Industrial wastewater contains a large amount of pollutants such as heavy metals, organic matter, viruses and bacteria, which are extremely harmful to the environment and organisms. Wastewater treatment can effectively remove these pollutants, reduce the harm to the environment and organisms, and thus protect the environment and human health.

[0003] Flocculant is a chemical agent widely used in the process of industrial wastewater treatment. It is added to the reaction tank to remove suspended matter, suspended solids and colloidal substances in the wastewater. The flocculant generally needs to be prepared into a liquid of a certain concentration and then added to the reaction tank. It also needs to be stirred in time after the addition of the flocculant to ensure that the flocculant is evenly distributed in the sewage. The stirring rate is also directly related to the intensity of the flocculant spraying. In the initial stage after the addition of the flocculant, it is usually necessary to stir quickly first to allow the flocculant to disperse quickly and contact with the colloid particles in the water sample, so that the colloid particles flocculate and produce micro-flocculation. The larger the amount of flocculant sprayed, the higher the stirring speed should be to ensure that the flocculant can be quickly dispersed and contact with the colloid particles after being sprayed into the reaction tank.

[0004] Although the existing adding device is provided with a spraying component and a stirring component, the positions of the spraying component and the stirring component are fixed, and the spraying intensity and the stirring rate need to be adjusted separately, and the spraying intensity and the stirring rate of the flocculant cannot be adjusted synchronously and synergistically at the same time. Based on this, an industrial wastewater treatment flocculant adding equipment is proposed. Summary of the Invention

[0009] Preferably, the second driving mechanism includes a rotating column rotatably connected to both sides of the bottom of the supporting plate, and transmission wheels are sleeved on the bottom of the rotating column and the rotating rod. The two transmission wheels are connected by a transmission belt. The two ends of the turbine are fixedly connected to a rotating shaft, and the rotating shaft extends through and extends to the outside of the pump water tank and is fixedly sleeved with a first bevel gear, the first bevel gear is meshed and connected with a second bevel gear, and the second bevel gear is fixedly sleeved on the top of the rotating column.

[0016] Beneficial effects of the industrial wastewater treatment flocculant addition equipment of the present invention:

[0017] (1) The present invention drives the threaded rod to rotate by rotating the motor. The rotation of the threaded rod causes the moving seat to drive the horizontal plate of the side wall and the rotating rod at the bottom to move, and then drives the spraying assembly under the horizontal plate and the stirring piece at the bottom of the rotating rod to move, so as to continuously change the spraying and stirring position of the flocculant in the reaction tank. When the rotating rod moves with the moving seat, the gear on the rotating rod meshes with the rack, so that the gear drives the rotating rod and the stirring piece at the bottom to rotate, spraying and stirring at the same time, and drives the transmission wheel at the bottom to rotate when the rotating rod rotates. Under the transmission action of the transmission belt, the rotating column rotates synchronously, and the rotating column is rotated. The second bevel gear engages with the first bevel gear and rotates, so that the rotating shaft drives the turbine to rotate rapidly, the contact area between the liquid and the turbine blades increases, and the ability to suck and discharge the liquid is increased, thereby increasing the flow rate of the flocculant, thereby increasing the amount of flocculant sprayed by the spray assembly. The moving speed of the spray assembly and the stirring member on the cross bar is proportional to the stirring rate of the stirring member and the rotation speed of the turbine. When the spray assembly and the stirring member move faster on the cross plate, the rotation rate of the stirring member is also faster, and the amount of flocculant sprayed by the spray assembly also increases accordingly. The three automatically adjust and cooperate to achieve the effect of uniform spraying and mixing of the flocculant.

[0018] (2) The present invention arranges a connecting rod, a spiral blade and a rotatable nozzle in the liquid outlet pipe. The liquid after the flow rate is increased by the turbine enters the liquid outlet pipe and drives the spiral blade to rotate, thereby driving the connecting rod and the nozzle fixedly connected to the connecting rod to rotate, so that the nozzle sprays the flocculant into the reaction tank more evenly. Moreover, the greater the flow rate and flow rate of the liquid flowing into the liquid outlet pipe, the faster the rotation speed of the nozzle. Therefore, the rotation rate of the nozzle and the spraying amount of the nozzle also work together to further improve the uniformity of flocculant addition. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figure 1-7As shown, an industrial wastewater treatment flocculant addition equipment comprises a liquid storage tank 1, and legs are fixedly provided on both sides of the bottom of the liquid storage tank 1, and cross plates 2 are fixedly provided on both sides of the bottom of the liquid storage tank 1, and the bottom of the cross plate 2 is movably connected to a rotating rod 3, and a stirring member 4 is fixedly provided at the bottom of the rotating rod 3, and a supporting plate 5 is movably connected between the two cross plates 2. A moving mechanism for synchronous movement of the rotating rod 3 and the supporting plate 5 and a first driving mechanism for driving the rotating rod 3 to rotate are provided in the cross plate 2, and a pump water tank 6 is fixedly provided in the middle of the bottom of the supporting plate 5, and the top of the pump water tank 6 is connected to the liquid storage tank 1 through an infusion hose 7, and a spray assembly is fixedly provided at the bottom of the pump water tank 6, and a turbine 8 is rotatably connected in the pump water tank 6, and a second driving mechanism for rotating the turbine 8 is provided on both sides of the bottom of the supporting plate 5, and the moving mechanism, the first driving mechanism and the second driving mechanism act in linkage.

[0029] The moving mechanism includes a groove 9 formed at the bottom of the horizontal plate 2, a threaded rod 10 being rotatably connected in the groove 9, one side of the threaded rod 10 passing through the horizontal plate 2 and being fixedly connected to a rotating motor 11, a moving seat 12 being threadedly connected to the threaded rod 10, and the rotating rod 3 being rotatably connected to the bottom of the moving seat 12. A through groove 13 is formed on one side of the horizontal plates 2 on both sides close to each other, and both ends of the supporting plate 5 pass through the through groove 13 and are fixedly connected to the side walls of the moving seat 12. The rotating motor 11 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 causes the moving seat 12 to drive the horizontal plate 2 on the side wall and the rotating rod 3 at the bottom to move, thereby driving the spraying assembly below the horizontal plate 2 and the stirring member 4 at the bottom of the rotating rod 3 to move, thereby changing the position of spraying and stirring the flocculant in the reaction tank.

[0030] The first drive mechanism includes a gear 14 fixedly mounted on the rotating rod 3. A rack 15 is fixedly mounted on the inner wall of one side of the groove 9. The gear 14 is meshed with the rack 15. As the rotating rod 3 moves with the movable base 12, the gear 14 on the rotating rod 3 meshes with the rack 15, causing the gear 14 to drive the rotating rod 3 and the stirring element at its bottom to rotate, thereby spraying and stirring the mixture as it moves, thereby improving the uniformity of the flocculant spraying and mixing.

[0031] The second driving mechanism includes a rotating column 16 rotatably connected to both sides of the bottom of the supporting plate 5, and a transmission wheel 17 is sleeved on the bottom of the rotating column 16 and the rotating rod 3. The two transmission wheels 17 are connected by a transmission belt 18. The two ends of the turbine 8 are fixedly connected to a rotating shaft 19, and the rotating shaft 19 extends through the outside of the pump water tank 6 and is fixedly sleeved with a first bevel gear 20. The first bevel gear 20 is meshed with a second bevel gear 21, and the second bevel gear 21 is fixedly sleeved on the top of the rotating column 16.

[0032] When the rotating rod 3 rotates, the transmission wheel 17 at the bottom is driven to rotate. Under the transmission action of the transmission belt 18, the rotating column 16 rotates synchronously, and the second bevel gear 21 on the rotating column 16 engages the first bevel gear 20 to rotate, so that the rotating shaft 19 drives the turbine 8 to rotate rapidly, thereby increasing the contact area between the liquid and the blades of the turbine 8, thereby increasing the ability to absorb and discharge the liquid, increasing the flow rate of the liquid, and thus increasing the amount of flocculant sprayed by the spray assembly. The moving speed of the spray assembly and the stirring member on the cross bar is proportional to the stirring rate of the stirring member and the turbine rotation speed. Therefore, the faster the spray assembly and the stirring member 4 move on the cross plate 2, the faster the stirring member 4 rotates, and the amount of flocculant sprayed by the spray assembly also increases. The three automatically adjust to achieve the effect of uniform spraying and mixing of the flocculant.

[0033] The diameter of the second bevel gear 21 is larger than the diameter of the first bevel gear 20. When the second bevel gear 21 engages with the first bevel gear 20 and rotates, the first bevel gear 20 can quickly drive the rotating shaft 19 and the turbine 8 to rotate, thereby increasing the flow rate and flow of the liquid flowing into the spray assembly below.

[0034] The spray assembly includes a liquid outlet pipe 22 fixedly arranged at the bottom of the pump water tank 6, a rotating seat 23 fixedly arranged inside the liquid outlet pipe 22, a connecting rod 24 rotatably connected to the middle of the rotating seat 23 through a bearing, a spiral blade 25 fixedly provided around the outer side of the connecting rod 24, and a nozzle 26 rotatably connected to the end of the liquid outlet pipe 22, and the connecting rod 24 is fixedly connected to the inner wall of the nozzle 26. The liquid with a flow rate increased by the rotation of the turbine 8 enters the liquid outlet pipe 22 and drives the spiral blade 25 to rotate, thereby driving the connecting rod 24 and the nozzle 26 fixedly connected to the connecting rod 24 to rotate, so that the nozzle 26 sprays the flocculant into the reaction tank more evenly.

[0035] The rotating seat 23 is provided with swirl grooves 27 inside. There are eight swirl grooves 27 evenly distributed on the rotating seat 23. The fast water flow generates vortexes after passing through the swirl grooves 27, which can better drive the spiral blades 25 to rotate.

[0036] Nozzles 28 are fixedly provided at the bottom and around the nozzle 26, and the nozzles 28 around the nozzle 26 are set to be tilted downward by 30°. As the nozzle 26 rotates, the nozzles 28 can spray flocculant into the reaction tank 360° without dead angles, thereby improving the uniformity of flocculant addition and facilitating full contact between the flocculant and the colloid particles in the wastewater.

[0037] Hydraulic rods 29 are fixedly connected to both sides of the bottom of the liquid storage tank 1, and the hydraulic rods 29 are fixedly connected to the top of the cross plate 2. The cross plate 2 is moved up and down by the lifting of the hydraulic rods 29, and then the stirring member 4 and the spraying assembly are driven to move downward, so that the stirring member 4 moves into the reaction tank and the spraying assembly is close to the reaction tank, thereby improving the uniformity of spraying and stirring of the flocculant.

[0038] The rotating shaft 19 includes a fixedly connected transverse shaft 30 and an electric telescopic rod 31. The transverse shaft 30 is fixedly connected to the turbine 8. The end of the electric telescopic rod 31 is fixedly connected to the first bevel gear 20. When the flocculant is sprayed from one end of the transverse plate 2 to the other end, the rotating motor 11 is reversed to make the stirring member 4 and the spraying assembly return to their original positions. The electric telescopic rod 31 is started to drive the first bevel gear 20 to move away from the second bevel gear 21, so that the first bevel gear 20 is separated from the second bevel gear 21, thereby avoiding the turbine 8 from reversing during the movement and affecting the flow path and speed of the water.

[0039] The infusion hose 7 is fixedly provided with an electromagnetic valve 32 to facilitate controlling the flocculant mixture in the liquid storage tank 1 to flow into the infusion hose 7 .

[0040] A dosing box is fixedly provided on one side of the top of the liquid storage tank 1, a dosing pipe connected to the liquid storage tank 1 is fixedly provided on the bottom of the dosing box, and a solenoid valve is provided on the dosing pipe. A liquid adding pipe is fixedly provided on one side of the liquid storage tank 1, and the liquid adding pipe is connected to an external water source. A mixing rod is rotatably connected inside the liquid storage tank 1, and mixing blades are evenly fixed on the side walls of the mixing rod. One end of the mixing rod passes through the liquid storage tank 1 and is fixedly connected to a stirring motor, which facilitates the configuration of the flocculant and uniform mixing.

[0041] During use, the liquid storage tank 1 is placed above the reaction tank, and flocculant and water in appropriate proportions are added into the liquid storage tank 1 and mixed evenly. When adding flocculant, first open the solenoid valve 32 on the infusion hose 7 so that the mixed liquid in the liquid storage tank 1 can enter the spray assembly, start the hydraulic rod 29 to drive the cross plate 2 to move downward, and then drive the stirring member 4 and the spray assembly to move downward, so that the stirring member 4 moves into the reaction tank and the spray assembly is close to the reaction tank, start the rotating motor 11 to drive the threaded rod 10 to rotate, and the rotation of the threaded rod 10 causes the moving seat 12 to drive the cross plate 2 of the side wall and the rotating rod 3 at the bottom to move, thereby driving the spray assembly below the cross plate 2 and the stirring member 4 at the bottom of the rotating rod 3 to move above the reaction tank, and at the same time, the gear 14 on the rotating rod 3 is meshed with the rack 15. Under the cooperative action, the gear 14 drives the rotating rod 3 and the stirring member at the bottom thereof to rotate, and under the transmission action of the transmission wheel 17 and the transmission belt 18, the rotating column 16 and the second bevel gear 21 rotate synchronously, and the second bevel gear 21 engages with the first bevel gear 20 to rotate, so that the rotating shaft 19 drives the turbine 8 to rotate rapidly, thereby increasing the ability to absorb and discharge the liquid, and increasing the amount of flocculant sprayed by the spray assembly, so that the moving speed of the spray assembly and the stirring member on the cross bar is proportional to the stirring rate of the stirring member and the rotation speed of the turbine. When the spray assembly and the stirring member 4 move faster on the cross plate 2, the rotation rate of the stirring member 4 is also faster, and the amount of flocculant sprayed by the spray assembly also increases accordingly. The three automatically adjust to achieve the effect of uniform spraying and mixing of the flocculant.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
