After a period of use, a large amount of reactants are deposited at the bottom of the reaction tank. The sediment at the bottom of the reaction tank needs to be cleaned frequently. Each time the device is processed, it is necessary to shut down, which is very inconvenient. In addition, when cleaning, the sediment is easy to disperse and float in the water, resulting in turbidity of the sewage after the reaction, and it is necessary to wait for the sediment to settle again.

DETAILED DESCRIPTION

[0029] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 8 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0030] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0031] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0032] Embodiment 1, a silicon removal device for sewage treatment, comprising a reaction tank 1 and a mud outlet 2 opened at the bottom of the reaction tank 1, a fixing frame 3 is fixedly installed inside the reaction tank 1, a plurality of shielding plates 4 are arranged at intervals on the fixing frame 3, one end of the shielding plate 4 is hinged on the fixing frame 3, the shielding plate 4 is hinged on one end of the fixing frame 3 and a pushing plate 5 is fixedly installed, the pushing plate 5 and the shielding plate 4 are arranged vertically, the pushing plate 5 is installed on the lower end surface of the shielding plate 4, a driving frame 6 is slidably connected inside the reaction tank 1, the driving frame 6 is located below the fixing frame 3, slide grooves are installed on both sides of the fixing frame 3, the driving frame 6 is slidably installed inside the slide groove, a plurality of toggle plates 7 arranged at intervals are fixedly connected to the driving frame 6, the toggle plate 7 is used to push the pushing plate 5 so as to control the rotation of the shielding plate 4, so that two adjacent shielding plates 4 are separated from each other, the driving frame 6 is connected with a pushing structure, and the pushing structure is used to push the driving frame 6 to slide inside the reaction tank 1;

[0033] A scraper plate 8 is slidably connected to the bottom of the reaction tank 1 . The scraper plate 8 is connected to a belt transmission structure. The belt transmission structure is used to push the scraper plate 8 to slide on the bottom of the reaction tank 1 .

[0034] The belt drive structure includes a driving wheel and a driven wheel installed on both sides of the reaction tank 1, a driving belt is connected between the driving wheel and the driven wheel, and the scraper 8 is fixedly connected to the driving belt. One of the driving wheels is connected to the driving motor through a belt. The driving motor is installed above the reaction tank to prevent the motor from being damaged by water.

[0035] When in use, the driving frame 6 is pushed to slide under the fixed frame 3, so that the toggle plate 7 and the pushing plate 5 are in contact, and then the toggle plate 7 pushes the pushing plate 5 to rotate, so that the upper end surfaces of the pushing plate 5 and the toggle plate 7 fit together. At this time, the pushing plate 5 pushes the shielding plate 4 to be in a vertical state. At this time, the shielding plates 4 are separated from each other, and the precipitates after the reaction in the sewage fall into the bottom of the reaction tank through the gaps between the shielding plates 4; when it is necessary to clean the bottom of the sedimentation tank, the driving frame 6 is pushed to slide, so that the pushing plate 5 and the toggle plate 7 are separated, and the two adjacent shielding plates 4 fit together, thereby covering the precipitates under the fixed frame 3, preventing the precipitates from being dispersed and mixed into the sewage above the fixed frame 3 when the precipitates at the bottom of the reaction tank 1 are cleaned.

[0036] The push plate 5 is configured to be L-shaped, and is fixedly connected to the shielding plate 4 by bolts, so that it is easy to install and replace.

[0037] One end of the shielding plate 4 away from the pushing plate 5 is fixedly connected to a connecting plate 9, and an isolation column 10 is fixedly connected to the connecting plate 9. The other end of the shielding plate 4 is provided with an isolation groove 11 that cooperates with the isolation column 10. When two adjacent shielding plates 4 are in end-to-end contact and fit together, the isolation column 10 is located inside the isolation groove 11, thereby further preventing the sediment below the fixing frame 3 from drifting into the reacted sewage above the fixing frame 3 during cleaning.

[0038] The cross-sections of the isolation column 10 and the isolation groove 11 are set to be semicircular, so that the isolation column 10 and the isolation groove 11 are easy to match.

[0039] A gravity block 12 is installed at one end of the shielding plate 4 away from the pushing plate 5. During use, when the pushing plate 5 and the toggle plate 7 are separated, the end of the shielding plate 4 away from the pushing plate 5 is pulled downward under the action of the gravity block 12, so that the two adjacent shielding plates 4 are fitted together, and the isolation column 10 and the isolation groove 11 are in contact and fit more closely.

[0040] The pushing structure includes a pushing rod 13 slidably connected inside the reaction pool 1. The pushing rod 13 is vertically installed on one side of the reaction pool 1. One end of the pushing rod 13 is connected to the driving frame 6 through a connecting rod 14. The other end of the pushing rod 13 is fixedly connected to a linear pushing device. The linear pushing device can be a cylinder, a hydraulic cylinder or an electric push rod. The pushing rod 13 is pushed toward or away from the bottom of the reaction pool 1. The driving frame 6 is pushed or pulled to slide by the connecting rod 14, thereby controlling the contact or separation of the toggle plate 7 and the pushing plate 5.

[0041] When there is no need to clean the bottom of the reaction pool 1, push the push rod 13 to slide upward, thereby driving the drive frame 6 to slide through the connecting rod 14, and the toggle plate 7 and the push plate 5 come into contact. Under the action of the push plate 5, the shielding plate 4 is in a vertical state, and the precipitate after the reaction passes through the gap between the two adjacent shielding plates 4 and falls to the bottom of the reactant 1.

[0042] When the bottom of the reaction tank 1 needs to be cleaned, the push rod 13 is pushed to slide downward, thereby driving the drive frame 6 to slide through the connecting rod 14, and the toggle plate 7 and the push plate 5 are separated. At this time, the two adjacent masking plates 4 are fitted end to end to cover the sediment at the bottom of the reaction tank 1, and the scraper plate 8 is pushed to slide on the bottom of the reaction tank 1 through the belt drive structure, pushing the sediment to the mud outlet 2, so that it is pushed out from the direction of the mud outlet 2.

[0043] Embodiment 2, on the basis of embodiment 1, when cleaning the sediment at the bottom of the reaction tank 1, the sediment is easy to drift around along the scraper 8, so this embodiment provides a scraper structure to solve the above problem. Specifically, the mud outlet 2 is set at one end of the reaction tank 1, and the scraper 8 is obliquely set at the bottom of the reaction tank 1, and the scraper 8 is inclined in the direction close to the mud outlet 2, so that when in use, the upper end of the scraper 8 is inclined in the direction close to the mud outlet 2. When cleaning, the scraper 8 pushes the sediment in the direction close to the mud outlet 2. The sediment drifts upward under the action of water force and thrust, and then hits the scraper 8 and drifts in the direction close to the mud outlet 2.

[0044] Mounting plates 15 are slidably connected to both sides of the bottom of the reaction tank 1. Torsion springs are connected between the mounting plates 15 and the scraper plates 8. When in use, the torsion springs push the lower end of the scraper plates 8 to always fit the bottom of the reaction tank 1.

[0045] Embodiment 3, on the basis of embodiment 2, after the scraper pushes the sediment to the mud outlet and returns to its original position, the scraper pushes the sediment that has not been pushed to the mud outlet in a direction away from the mud outlet, so that the sediment is mixed with the sewage again, which is inconvenient for subsequent cleaning. Therefore, this embodiment provides a control structure to solve the above problem. Specifically, a belt transmission structure is installed on both sides of the reaction tank 1, and the belt transmission structure is located below the fixed frame 3. The belt transmission structure is used to drive the mounting plate 15 to slide inside the reaction tank 1. A control slider 17 is slidably connected to the mounting plate 15. A guide block 18 that matches the scraper 8 is fixedly connected to the control slider 17. The cross-section of the guide block 18 is set to be trapezoidal. A scraper control plate 19 and a reset control plate 20 are fixedly connected on both sides of the reaction tank 1. The reset control plate 20 is installed at the end close to the mud outlet 2. The scraper control plate 19 is located at the end of the reaction tank 1 away from the mud outlet 2. The scraper control plate 19 and the reset control plate 20 are used to push the control slider 17 to slide, thereby controlling the angle of the scraper 8.

[0046] When in use, when the belt transmission structure drives the mounting plate 15 to slide toward the mud outlet 2, under the action of the torsion spring, the lower end of the scraper plate 8 is always in contact with the bottom of the reaction tank 1. When the mounting plate 15 slides to the limit position in the direction close to the mud outlet 2, after the control slider 17 contacts the reset control plate 20, the reset control plate 20 pushes the control slider 17 in the direction away from the mud outlet 2, so that the inclined surface of the guide block 18 pushes the scraper plate 8 and compresses the torsion spring until the scraper plate 8 is pushed to be parallel to the toggle plate 7. Then, the horizontal surface of the guide block 18 and the scraper plate 8 are in contact, thereby limiting the scraper plate 8 to a position parallel to the toggle plate 7. Therefore, when the belt transmission structure drives the mounting plate 15 to slide in the direction away from the mud outlet 2, the scraper plate 8 does not push the sediment in the direction away from the mud outlet 2.

[0047] When the belt transmission structure drives the mounting plate 15 to slide toward the mud outlet 2, the control slider 17 contacts the scraper control plate 19, so that the scraper control plate 19 pushes the control slider 17 toward the mud outlet 2, so that the guide block 18 and the scraper plate 8 are separated. At this time, under the action of the torsion spring, the lower end of the scraper plate 8 is always in contact with the bottom of the reaction tank 1.

[0048] Embodiment 4, on the basis of embodiment 1, this embodiment provides a discharging structure, a discharging bin 21 is fixedly connected below the mud outlet 2, a discharging box 22 is slidably connected inside the discharging bin 21, a through hole 23 matching the mud outlet is opened on the discharging box, the through hole 23 is opened at one end of the discharging box 22 away from the center of the reaction tank 1, when in use, after the scraper 8 pushes the sediment to the position of the mud outlet 2, the sediment falls into the through hole 23, when cleaning, the discharging box 22 is drawn out from the inside of the discharging bin 21 until the through hole 23 leaks out, so that the sediment falls from the bottom of the through hole 23 for collection and treatment, when the discharging box 22 is drawn out from the inside of the discharging bin 21, the rest of the discharging box 22 blocks the mud outlet 2 to prevent the water inside the reaction tank 1 from flowing out through the through hole 23, and when in specific use, a hydraulic cylinder or a pneumatic cylinder can be used to push the discharging box 22 to slide inside the discharging bin 21.

[0049] When it comes to specific implementation,

[0050] When there is no need to clean the bottom of the sedimentation tank, push the push rod 13 to slide upward, thereby driving the driving frame 6 to slide through the connecting rod 14, and pushing the driving frame 6 to slide under the fixed frame 3, so that the toggle plate 7 and the push plate 5 are in contact, and then the toggle plate 7 pushes the push plate 5 to rotate, so that the upper end surfaces of the push plate 5 and the toggle plate 7 fit together, and at this time, the push plate 5 pushes the shielding plate 4 to be in a vertical state, and at this time, the shielding plates 4 are separated from each other, and the reacted sediment in the sewage falls to the bottom of the reaction tank through the gap between the shielding plates 4;

[0051] When the bottom of the sedimentation tank needs to be cleaned, the push rod 13 is pushed downward to slide, thereby driving the driving frame 6 to slide through the connecting rod 14, pushing the driving frame 6 to slide, separating the push plate 5 and the toggle plate 7, and making the two adjacent shielding plates 4 fit together, thereby covering the sediment under the fixed frame 3, preventing the sediment at the bottom of the reaction tank 1 from being dispersed and mixed into the sewage above the fixed frame 3 when cleaning.

[0052] When in use, when the belt transmission structure drives the mounting plate 15 to slide toward the mud outlet 2, under the action of the torsion spring, the lower end of the scraper plate 8 is always in contact with the bottom of the reaction tank 1. When the mounting plate 15 slides to the limit position in the direction close to the mud outlet 2, after the control slider 17 contacts the reset control plate 20, the reset control plate 20 pushes the control slider 17 in the direction away from the mud outlet 2, so that the inclined surface of the guide block 18 pushes the scraper plate 8 and compresses the torsion spring until the scraper plate 8 is pushed to be parallel to the toggle plate 7. Then, the horizontal surface of the guide block 18 and the scraper plate 8 are in contact, thereby limiting the scraper plate 8 to a position parallel to the toggle plate 7. Therefore, when the belt transmission structure drives the mounting plate 15 to slide in the direction away from the mud outlet 2, the scraper plate 8 does not push the sediment in the direction away from the mud outlet 2.

[0053] When the belt transmission structure drives the mounting plate 15 to slide toward the mud outlet 2, the control slider 17 contacts the scraper control plate 19, so that the scraper control plate 19 pushes the control slider 17 toward the mud outlet 2, so that the guide block 18 and the scraper plate 8 are separated. At this time, under the action of the torsion spring, the lower end of the scraper plate 8 is always in contact with the bottom of the reaction tank 1.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
