Description

Technical Field

[0001] This utility model relates to the field of flocculation and sedimentation technology, and in particular to a flocculation and sedimentation device for wastewater treatment. Background Technology

[0002] Flocculation and sedimentation is the process by which particulate matter flocculates and settles in water. After adding a coagulant to water, the colloidal and dispersed particles of suspended solids form flocs under the interaction of molecular forces. During sedimentation, these flocs collide and aggregate, continuously increasing in size and mass, and their settling velocity. Flocculation and sedimentation occur in surface water after adding coagulants, in domestic sewage, in activated sludge, and in other sedimentation processes.

[0003] When flocculating and settling wastewater, the settled flocs need to be removed. This is usually done at the bottom of the settling device. Most flocculation and settling devices are equipped with a stirring mechanism at the bottom. The purpose of this mechanism is to prevent the flocs from clogging the settling device by stirring. However, during stirring, the flocs will inevitably be dispersed to the upper part of the flocculation and settling device, causing the water in the upper part of the flocculation and settling device to become turbid again.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a flocculation and sedimentation device for wastewater treatment, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flocculation and sedimentation device for wastewater treatment, comprising a connecting base plate, a support column fixedly installed on the upper end of the outer wall of the connecting base plate, a sedimentation frame fixedly installed on the upper end of the outer wall of the support column, an annular locking block fixedly installed in the middle of the inner side wall of the sedimentation frame, rotating seats symmetrically fixedly installed on the upper end of the outer wall of the annular locking block, a semi-circular closed door rotatably connected to each of the two rotating seats, a discharge frame fixedly installed on the lower end of the outer wall of the sedimentation frame, a discharge port fixedly connected to the front end of the outer wall of the discharge frame, and a valve fixedly installed on the discharge port.

[0007] As a further technical solution of this utility model, an arc-shaped rubber retainer is fixedly installed at the lower end of the outer wall of each of the two semi-circular closed doors, and a semi-circular rubber sealing strip is fixedly installed on the opposite side of the outer wall of each of the two semi-circular closed doors.

[0008] As a further technical solution of this utility model, rotating connecting sleeves are symmetrically fixedly installed on the front end of the side wall of the sedimentation frame. Rotating rods are rotatably connected inside the two rotating connecting sleeves. The front ends of the outer walls of the two rotating rods pass through the rotating seat and are fixedly connected to the semi-circular closed door. Gear 1 is fixedly installed on the rear end of the outer wall of the rotating rod on the right. A connecting column is fixedly installed on the upper end of the outer wall of the connecting base plate. Rotating shaft 1 is rotatably connected to the rear end of the outer wall of the connecting column. Gear 2 is fixedly connected to the rotating shaft 1. Gear 2 meshes with gear 1. Pulley 1 is fixedly installed on one side wall of the rotating shaft and at the front end of the outer wall of gear 1. Pulley 2 is fixedly installed on the side wall of the rotating rod on the left. A transmission belt is connected between pulley 2 and pulley 1.

[0009] As a further technical solution of this utility model, a connecting plate is fixedly installed on the connecting column, and a rotating motor is fixedly installed on the upper end of the outer wall of the connecting plate. The output end of the rotating motor is fixedly connected to the rear end of the outer wall of the rotating shaft.

[0010] As a further technical solution of this utility model, a support plate is fixedly installed on the support column, a drive motor is fixedly installed on the upper end of the outer wall of the support plate, a rotating shaft two that passes through the inside of the discharge frame is fixedly connected to the output end of the drive motor, a cross-shaped connecting frame is fixedly installed on the upper end of the outer wall of the rotating shaft two, and scraper rods are fixedly installed in a circumferential arrangement on the cross-shaped connecting frame.

[0011] As a further technical solution of this utility model, reinforcing rings are fixedly installed on the side wall of the cross-shaped connecting frame and on all the side walls of the scraper.

[0012] This utility model provides a flocculation and sedimentation device for wastewater treatment, which has the following advantages compared with the prior art:

[0013] 1. When using this utility model, if it is necessary to remove the flocculent sediment in the sedimentation frame, the rotation of the motor drives the rotating shaft to rotate. The rotation of the rotating shaft causes the two rotating rods on the left and right sides to rotate in opposite directions, thereby closing the two semi-circular closed doors simultaneously. By closing the two semi-circular closed doors, the upper and lower parts of the sedimentation frame can be separated, preventing the flocculent sediment at the bottom of the sedimentation frame from being dispersed back to the top of the sedimentation frame due to agitation when it is discharged, thus avoiding secondary pollution of the water above the sedimentation frame.

[0014] 2. In use, the drive motor drives the rotating shaft to rotate, thereby rotating the cross-shaped connecting frame and the scraper. The rotation of the scraper removes the flocculent precipitate adhering to the lower part of the inner wall of the sedimentation frame, thus preventing the flocculent precipitate from accumulating and clogging the lower part of the inner wall of the sedimentation frame because it cannot fall off naturally.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution for a flocculation and sedimentation device for wastewater treatment: It includes a connecting base plate 100, a support column 200 fixedly installed on the upper part of the outer wall of the connecting base plate 100, a sedimentation frame 300 fixedly installed on the upper part of the outer wall of the support column 200, an annular locking block 400 fixedly installed in the middle of the inner side wall of the sedimentation frame 300, rotating seats 410 symmetrically fixedly installed on the upper part of the outer wall of the annular locking block 400, and semi-circular closed doors 420 rotatably connected to each of the two rotating seats 410. A discharge frame 500 is fixedly installed on the lower part of the outer wall of the sedimentation frame 300, and a discharge port 510 is fixedly connected to the front end of the outer wall of the discharge frame 500. A valve 52 is fixedly installed on the discharge port 510. 0. Valve 520 is used to open and close the discharge port 510. After the sewage is discharged into the sedimentation frame 300, the staff adds flocculant to the sedimentation frame 300 to cause the sewage in the sedimentation frame 300 to flocculate and settle. The resulting flocculent sediment will settle at the conical bottom of the sedimentation frame 300. When it is necessary to remove the flocculent sediment in the sedimentation frame 300, the upper and lower parts of the sedimentation frame 300 can be separated by closing the two semi-circular sealing doors 420. This prevents the flocculent sediment at the bottom of the sedimentation frame 300 from being dispersed again to the top of the sedimentation frame 300 due to agitation when it is discharged, which would cause the water above the sedimentation frame 300 to become turbid again.

[0023] Both semi-circular closed doors 420 are fixedly installed with arc-shaped rubber retaining rings 430 at the lower ends of their outer walls, and semi-circular rubber sealing strips 440 are fixedly installed on opposite sides of their outer walls. The sealing performance of the two semi-circular closed doors 420 can be increased by the interlocking of the arc-shaped rubber retaining rings 430 and the ring-shaped retaining block 400 and the mutual compression of the two semi-circular rubber sealing strips 440. A rotating connecting sleeve 600 is symmetrically fixedly installed on the front side wall of the sedimentation frame 300. A rotating rod 610 is rotatably connected inside each of the two rotating connecting sleeves 600. The front ends of the outer walls of both rotating rods 610 pass through the rotating seat 410 and are fixedly connected to the semi-circular closed door 420. A gear 700 is fixedly installed at the rear end of the outer wall of the right rotating rod 610. A connecting column 710 is fixedly installed at the upper end of the outer wall of the connecting base plate 100. A rotating shaft 740 is rotatably connected to the rear end of the outer wall of the connecting column 710. A gear 750 is fixedly connected to the rotating shaft 740, meshing with the gear 700. A leather belt is fixedly installed on the side wall of the rotating shaft 740, located at the front end of the outer wall of the gear 700. A pulley 760 is attached to the left side of the rotating rod 610, and a belt 780 is connected between the pulley 770 and the pulley 760. The rotation of the rotating shaft 740 drives the gear 750, which in turn rotates the gear 700 and the right rotating rod 610. Simultaneously, the left rotating rod 610 rotates via the pulley 760, belt 780, and pulley 770. The two rotating rods 610 rotate in opposite directions, allowing the two semi-circular closed doors 420 to open or close simultaneously. A connecting plate 720 is fixedly mounted on the connecting column 710. A rotating motor 730 is fixedly mounted on the upper outer wall of the connecting plate 720. The output end of the rotating motor 730 is fixedly connected to the rear end of the outer wall of the rotating shaft 740. The rotation of the motor 730 drives the rotating shaft 740 to rotate.

[0024] like Figure 1-5 As shown, a support plate 800 is fixedly installed on the support column 200. A drive motor 810 is fixedly installed on the upper end of the outer wall of the support plate 800. The output end of the drive motor 810 is fixedly connected to a rotating shaft 820 that penetrates the inside of the discharge frame 500. A cross-shaped connecting frame 830 is fixedly installed on the upper end of the outer wall of the rotating shaft 820. Scraper rods 840 are fixedly installed circumferentially on the cross-shaped connecting frame 830. When the drive motor 810 is started, the rotating shaft 820 is rotated, thereby causing the cross-shaped connecting frame 830 and the scraper rods 840 to rotate. The rotation of the scraper rods 840 scrapes off the flocculent sediment adhering to the lower part of the inner side wall of the sedimentation frame 300. Reinforcing rings 850 are fixedly installed on the side wall of the cross-shaped connecting frame 830 and the side wall of all the scraper rods 840. The reinforcing rings 850 can strengthen the connection strength of all the scraper rods 840.

[0025] The working principle of this utility model is as follows: After sewage is discharged into the sedimentation frame 300, the operator adds flocculant to the sedimentation frame 300 to cause flocculation and sedimentation of the sewage. The resulting flocculent precipitate will settle at the conical bottom of the sedimentation frame 300. When it is necessary to remove the flocculent precipitate settled in the sedimentation frame 300, the rotation of the motor 730 drives the rotation shaft 740 to rotate. The rotation of the rotation shaft 740 drives the gear 750 to rotate, thereby causing the gear 700 and the right-side rotating rod 610 to rotate. At the same time, the left-side rotating rod 610 is rotated through the pulley 760, the transmission belt 780 and the pulley 770. The two rotating rods 610 on the left and right sides rotate in opposite directions, so that the rotation of the rotating shaft 740 causes the two rotating rods 610 to rotate in opposite directions, thereby closing the two semi-circular closed doors 420 at the same time. This prevents the flocculent sediment below the sedimentation frame 300 from being dispersed back to the top of the sedimentation frame 300 due to agitation when it is discharged, which would cause the water above the sedimentation frame 300 to become turbid again. At the same time, the starting of the drive motor 810 drives the rotating shaft 820 to rotate, thereby causing the cross-shaped connecting frame 830 and the scraper 840 to rotate. The rotation of the scraper 840 scrapes off the flocculent sediment adhering to the lower inner wall of the sedimentation frame 300.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
