Description

Technical Field

[0001] This utility model relates to the field of high-density sedimentation tank technology, specifically to an algae suppression device for high-density sedimentation tanks. Background Technology

[0002] In my country, especially in power plants, high-density sedimentation tanks are often used for raw water purification when space is limited. The purified water is then used for the plant's production and domestic water needs. The main process flow of a high-density sedimentation tank is as follows: Raw water enters the coagulation zone, where a coagulant is added and the mixture is rapidly stirred by an agitator, resulting in a coagulation reaction that produces small flocs. Then, it enters the flocculation zone, where a coagulant aid and activated sludge are added, and under the action of the impeller, large, high-density flocs are generated. Finally, it enters the sedimentation / concentration zone, where sludge and water are separated. The sludge is concentrated in the concentration zone, and the clear water is collected from the sedimentation zone by a collection trough at the top of the tank. The collected clarified water is then used for the plant's production and domestic water needs.

[0003] Chinese utility model patent CN215195547U discloses a device for improving the effluent quality of high-density sedimentation tanks, belonging to the field of water treatment technology. To address the problem of algae and other organic matter growing in the sedimentation / concentration zones of high-density sedimentation tanks, leading to poor effluent quality, the device mainly consists of support columns, a grid, a light-blocking cloth, and hooks. Support columns are installed on top of the sedimentation / concentration zones of the high-density sedimentation tank, providing support. A grid is laid on the support columns, and a light-blocking cloth is covered on the grid to block light. The light-blocking cloth is fixed around its perimeter with hooks to ensure that the sedimentation / concentration zones of the high-density sedimentation tank are free of light. This utility model is used to improve the effluent quality of high-density sedimentation tanks.

[0004] However, during the use of this utility model, staff need to manually cover the sedimentation tank, and the area of ​​the covering cannot be adjusted, which affects the actual use effect and cannot meet the usage requirements. Therefore, a high-density sedimentation tank algae suppression device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an algae suppression device for high-density sedimentation tanks, which has the advantage of automatically shielding the sedimentation tank. This solves the problem that existing suppression devices require manual shielding of the sedimentation tank by staff, and the shielding area cannot be adjusted, thus affecting the actual use effect and failing to meet the usage requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an algae suppression device for high-density sedimentation tanks, comprising a sedimentation tank body and a drive box fixedly connected to the front of the sedimentation tank body, wherein the sedimentation tank body is provided with an automatic shielding mechanism capable of suppressing algae.

[0007] The automatic shielding mechanism includes two fixed plates fixedly connected to the inner wall of the sedimentation tank body, a winding drum rotatably connected between the two fixed plates, a cable connected to the outside of the winding drum, a fixed seat fixedly connected to the side of the sedimentation tank body near the fixed plates, a first crossbar and a second crossbar respectively provided inside the sedimentation tank body, a shielding cloth fixedly connected between the fixed seat, the first crossbar and the second crossbar, and one end of the cable fixedly connected to the second crossbar.

[0008] Furthermore, the first crossbar is located between the fixed base and the second crossbar, and a limiting plate that can limit the cable is fixedly connected to the outside of the winding drum.

[0009] Furthermore, there are two cables and four limiting plates, with each cable distributed between two limiting plates.

[0010] Furthermore, a positioning guide rod is fixedly connected inside the sedimentation tank body, and a positioning sleeve is slidably connected to the outside of the positioning guide rod. A connecting rod is fixedly connected between the positioning sleeve and the first crossbar and the second crossbar.

[0011] Furthermore, there are two positioning guide rods, which are symmetrically distributed on the front and back sides of the sedimentation tank body.

[0012] Furthermore, a first pulley is rotatably connected inside the drive box, and a second pulley capable of rotating the winding drum is rotatably connected inside the drive box. A drive belt is connected between the first pulley and the second pulley.

[0013] Furthermore, a drive motor capable of driving the first pulley is fixedly connected to the front of the drive box, and the diameter of the first pulley is larger than the diameter of the second pulley.

[0014] Compared with the prior art, this utility model provides an algae suppression device for high-density sedimentation tanks, which has the following beneficial effects:

[0015] 1. This high-density sedimentation tank uses an algae suppression device. By setting a first crossbar and a second crossbar, the shielding cloth can be folded. A fixing seat is set to fix one side of the shielding cloth inside the sedimentation tank body. A winding drum is set to wind up and unwind the cable, which in turn drives the second crossbar to move left and right, thus facilitating the unfolding and folding of the shielding cloth. This allows workers to easily shield the sedimentation tank body and can shield different areas as needed.

[0016] 2. This high-density sedimentation tank algae suppression device uses a drive motor to rotate the first pulley, and a transmission belt and a second pulley to drive the winding drum, thereby achieving an automatic blocking effect. This further improves work efficiency and solves the problem that existing suppression devices require manual blocking of the sedimentation tank and cannot adjust the blocking area, thus affecting the actual use effect and failing to meet the usage requirements.

[0025] It should be noted that a positioning guide rod 11 is fixedly connected inside the sedimentation tank body 1, and a positioning sleeve 13 is slidably connected to the outside of the positioning guide rod 11. A connecting rod 12 is fixedly connected between the positioning sleeve 13 and the first crossbar 7 and the second crossbar 8. There are two positioning guide rods 11, which are symmetrically distributed on the front and back sides inside the sedimentation tank body 1.

[0026] It should be noted that the material of the covering cloth 9 is waterproof, which can prevent rainwater from seeping in. By setting the first crossbar 7 and the second crossbar 8, the covering cloth 9 can be folded. By setting the fixing seat 6, it is easy to fix one side of the covering cloth 9 inside the sedimentation tank body 1. By setting the winding drum 4, the cable 5 is wound up and unwound, which allows the cable 5 to drive the second crossbar 8 to move left and right, so as to facilitate the unfolding and folding of the covering cloth 9, making it convenient for staff to cover the sedimentation tank body 1.

[0029] The working principle of the above embodiments is as follows:

[0030] First, when the staff needs to cover the sedimentation tank body 1, they start the drive motor 17 to drive the winding drum 4 to rotate counterclockwise. At this time, the winding drum 4 will unwind the cable 5, and the second crossbar 8 will move to the right. At this time, the entire covering cloth 9 is in the unfolded state. When it is necessary to fold the covering cloth 9, the drive motor 17 is started to drive the winding drum 4 to rotate clockwise. At this time, the cable 5 is wound up, and the second crossbar 8 moves to the left, thereby folding the covering cloth 9.
