Description

Technical Field

[0001] The present invention relates to the technical field related to sewage treatment, and in particular to a silicon removal purification device for reclaimed water reuse and a method for using the same. Background Art

[0002] In the process of sewage treatment, silicon removal is a very important link. Silicon is a common pollutant in sewage, which can lead to water quality deterioration and pose a potential threat to the environment and human health. Therefore, the use of efficient silicon removal technology is crucial to the improvement of sewage treatment process.

[0003] The significance of silicon removal technology in sewage treatment cannot be underestimated. First, silicon will precipitate in the water to form solid particles. These particles adhere to pipes, equipment and filters, resulting in blockage of water treatment systems, increased maintenance and replacement frequency. Second, the presence of silicon particles will increase the pressure of the sedimentation tank, reduce the sedimentation effect, and affect the normal operation of subsequent treatment processes. Most importantly, silicon particles will also react chemically with other pollutants to produce organosilicon compounds that are more difficult to degrade, causing further harm to the environment and ecosystem.

[0004] Common silicon removal technologies include chemical precipitation, membrane separation and adsorption. Chemical precipitation can precipitate silicon ions into solid particles such as silicates by adding chemical reagents. Existing silicon removal purification devices generally add magnesium and liquid alkali to sewage. Silicon ions can be effectively removed through the full reaction of sewage and magnesium. However, when a stirring device is used for mixing reaction, the stirring rate cannot be changed according to the amount of magnesium added. In order to ensure the reaction rate, the motor can only be set to run at a high speed, which increases the power consumed during stirring and causes the cost of silicon removal purification work to rise.

The specific implementation method is as follows: See also Figure 1 to Figure 10 In an embodiment of the present invention, a silicon removal and purification device for reclaimed water reuse includes a receiving seat 1, on which a reaction tank 2 and a liquid storage tank 3 are arranged, and the reaction tank 2 is connected to the inner side of the liquid storage tank 3; It also includes a reciprocating drive member disposed on the receiving seat 1, and the reciprocating drive member can control the pumping mechanism installed in the liquid storage tank 3 to perform a pumping action; The adjusting mechanism is installed on the receiving seat 1, and the adjusting mechanism includes a first transmission member and a second transmission member. The second transmission member is connected to the stirring assembly arranged in the reaction tank 2, and the first transmission member is respectively connected to the pushing structure and the second transmission shaft 17 arranged on the receiving seat 1. The pushing structure and the second transmission shaft 17 are respectively connected to the reciprocating driving member to control the transmission ratio between the first transmission member and the second transmission member.

[0032] In detail, after the sewage is poured into the reaction tank 2, the reciprocating drive member is started to control the pumping mechanism to perform reciprocating pumping in the liquid storage tank 3, so that the magnesium agent and liquid alkali in the liquid storage tank 3 are squeezed into the reaction tank 2. While the reciprocating drive member is working, the second transmission shaft 17 and the pushing structure are controlled to move synchronously. Under the action of the first transmission member and the second transmission member, the stirring component is driven to perform the stirring action, and the stirring rate of the stirring component is changed with the addition of the magnesium agent and liquid alkali, so as to complete the desiliconization of the sewage, realize the full reaction of the sewage and the magnesium agent, accelerate the removal of silicon in the sewage, further increase the purification effect of the sewage, and reduce the power consumed by the stirring component.

[0033] As a further solution of the present invention, please refer to the figure, the pumping mechanism includes a piston 5, which is sealed and slidably connected to the inner wall of the liquid storage tank 3, and a movable shaft 4 is arranged along the axial direction of the piston 5. The end of the movable shaft 4 away from the piston 5 passes through the liquid storage tank 3 and is connected to the reciprocating drive member.

[0034] The reciprocating drive member includes a drive shaft 8 rotatably arranged on the receiving seat 1, the drive shaft 8 is driven to rotate by a motor 7 fixedly installed on the receiving seat 1, a first bevel gear 10 is arranged on the drive shaft 8, and a drive disk 9 is arranged on the end of the drive shaft 8 away from the motor 7, and a convex column 901 is formed at the eccentric position of the drive disk 9; It also includes a movable plate 6 slidably arranged on the receiving seat 1 through a guide rod 602, the movable plate 6 is fixedly connected to the movable shaft 4, and a limiting groove 601 is formed at one end of the movable plate 6 away from the movable shaft 4 to slide with the boss 901.

[0035] Preferably, at least one group of second slide grooves 303 are formed on the inner wall of the liquid storage tank 3, and a second slider 501 slidingly connected to the second slide grooves 303 is provided on the outer ring of the piston 5.

The presence of the one-way valve ensures that when the pressure of the liquid storage tank 3 increases, the solution can only flow into the reaction tank 2 from the water outlet pipe 301, and when the pressure of the liquid storage tank 3 decreases, the external solution enters through the water inlet pipe 302.

[0037] To elaborate, after the sewage is poured into the reaction tank 2, the motor 7 is started, and the output shaft of the motor 7 is fixedly connected to the drive shaft 8. When the output shaft rotates, it drives the drive shaft 8 to rotate synchronously. When the drive shaft 8 rotates, it drives the drive disk 9 to rotate accordingly, so that the convex column 901 thereon squeezes the movable plate 6. Under the action of the guide rod 602, the drive disk 9 rotates one circle, and the movable plate 6 completes a set of reciprocating movements. When the movable plate 6 moves, it drives the movable shaft 4 to move synchronously to realize the pumping of the solution in the liquid storage tank 3.

[0038] As a further solution of the present invention, please refer to the figure, the stirring assembly includes a stirring shaft 19, one end of the stirring shaft 19 is rotatably connected to the filtering mechanism arranged at the bottom of the reaction tank 2, and the other end is rotatably connected to the top of the reaction tank 2. A plurality of stirring blades 21 are radially arranged on the stirring shaft 19.

[0039] The second transmission member includes symmetrically arranged second transmission wheels 20 . The second transmission wheels 20 are arranged along the axial direction of the stirring shaft 19 , and a transmission belt 18 is sleeved between two second transmission wheels 20 .

[0040] The first transmission member includes a symmetrically arranged first transmission wheel 16, which is arranged along the axial direction of the second transmission shaft 17, and at least one group of strip blocks 1601 is arranged on the inner ring of the first transmission wheel 16, and the strip blocks 1601 can be inserted into the strip grooves 1701 formed by the second transmission shaft 17 and are slidably connected to the strip grooves 1701, and the transmission belt 18 is arranged between the two first transmission wheels 16 at one end away from the first transmission wheel 16.

[0041] The pushing structure includes a bidirectional screw rod 13 rotatably arranged on the receiving seat 1, and the end of the bidirectional screw rod 13 is provided with a third bevel gear 15 meshing with the first bevel gear 10, and the bidirectional screw rod 13 is threadedly connected with a first threaded sleeve 14, and a limit block 1401 is formed on the first threaded sleeve 14, and the limit block 1401 can be inserted into the arc groove formed by the first transmission wheel 16 and is rotatably connected to the arc groove.

[0042] A first transmission shaft 11 is rotatably disposed on the receiving seat 1 , a second bevel gear 12 meshing with the first bevel gear 10 is disposed on the first transmission shaft 11 , and the first transmission shaft 11 is rotatably connected to the second transmission shaft 17 via a belt 22 .

[0043] Specifically, when the driving shaft 8 rotates, the first transmission shaft 11 is driven to rotate through the transmission of the first bevel gear 10 and the second bevel gear 12, and the second transmission shaft 17 is driven to rotate under the transmission of the belt 22, and the first bevel gear 10 is meshed with the third bevel gear 15 at the same time to drive the bidirectional screw rod 13 to rotate, so as to realize the requirement of synchronous rotation of the bidirectional screw rod 13 and the second transmission shaft 17, and the rotation speeds of the bidirectional screw rod 13 and the second transmission shaft 17 are different.

[0044] When the bidirectional screw 13 rotates, the two first threaded sleeves 14 are driven to make linear motion along the axial direction of the bidirectional screw 13, and the moving directions of the two first threaded sleeves 14 are opposite. When the distance between the two first threaded sleeves 14 is controlled to decrease, the two first transmission wheels 16 are driven to make linear motion along the axial direction of the second transmission shaft 17. At this time, the gap between the two first transmission wheels 16 is reduced, so that the position of the transmission belt 18 sleeved between the two first transmission wheels 16 is changed. When the two first transmission wheels 16 move, they squeeze the transmission belt 18, so that the transmission belt 18 moves along the radial direction of the first transmission wheel 16, and the first transmission wheel 16 and the second transmission wheel 20 always keep rotating to change the transmission ratio of the second transmission shaft 17 and the stirring shaft 19, and adjust the stirring rate of the stirring shaft 19.

[0045] In the initial state, the axial length of the position where the transmission belt 18 is sleeved on the two first transmission wheels 16 from the second transmission shaft 17 is at a minimum value. When the gap between the two first transmission wheels 16 decreases, the axial length of the position where the transmission belt 18 is sleeved on the two first transmission wheels 16 from the second transmission shaft 17 gradually increases, while the axial length of the position where the transmission belt 18 is sleeved on the two second transmission wheels 20 from the stirring shaft 19 gradually decreases, so as to achieve the adjustment of the rotation speed of the stirring shaft 19.

[0047] Preferably, a gap is formed between the sealing plate 23 and the inner wall of the reaction tank 2. The existence of this gap facilitates the separation of the filter plate 26 from the sealing plate 23. The purified water in the reaction tank 2 is discharged from the drain port 202 at the bottom of the reaction tank 2 through the filter plate 26, while the solids remain on the filter plate 26, so as to achieve solid-liquid separation in the reaction tank 2.

[0048] Preferably, at least one group of first slide grooves 201 is formed on the inner wall of the reaction tank 2 , and a first sliding block 2301 slidably matched with the first slide grooves 201 is provided on the blocking plate 23 .

Under the action of the stirring component, the magnesium agent and the liquid alkali fully react and neutralize with the sewage; Step 3: The reciprocating drive member works by controlling the pushing structure and the adjusting mechanism to act simultaneously, and controlling the stirring assembly to stir the solution in the reaction tank 2. At the same time, the transmission ratio between the first transmission member and the second transmission member is adjusted according to the amount of magnesium agent and liquid alkali added to change the stirring rate of the stirring assembly.
