Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a floating object salvaging structure for a primary sedimentation tank. Background Art

[0002] A primary sedimentation tank is a structure that uses sedimentation to remove suspended matter from water and is used as a water purification device. Suspended matter is removed by natural sedimentation or coagulation sedimentation. Primary sedimentation tanks are divided into horizontal and vertical types based on the direction of water flow. There are some floating objects in the primary sedimentation tank, such as plastic paper, leaves, and branches. These floating objects float inside the sewage sedimentation tank and need to be salvaged. Therefore, external salvage equipment is required for cleaning. However, existing salvage structures still have some problems when performing cleaning:

[0003] Low scooping efficiency. During the salvage and cleaning process of floating objects in the existing primary sedimentation tank, the salvage device has a small scooping area and the stuck garbage is not easy to fall off during the scooping process, resulting in a low scooping efficiency of the overall scooping structure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a floating object salvaging structure for a primary sedimentation tank.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] As a further solution of the present invention: a second waterproof motor is fixed to the inner wall of the guide tube by bolts, and the output shaft of the second waterproof motor is connected to the guide blade.

[0008] As a further solution of the present invention: a rotating shaft is rotatably mounted on the top outer wall of the fixed plate, and one end of the rotating shaft is connected to a servo motor through a coupling.

[0009] As a further solution of the present invention: fixed blocks distributed at equal distances are welded to the outer walls of both ends of the rotating shaft, and connecting rods are clamped and installed on the outer walls of the fixed blocks, and a salvage net is welded to the outer walls of the ends of the connecting rods.

Combined with the pushing process of the electric telescopic rod, it can effectively expand the salvage area and improve the cleaning effect. The reversible salvage net can quickly flip the garbage over to make it fall, avoiding garbage sticking.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0021] Example 1:

[0022] A floating object salvage structure for a primary sedimentation tank. This embodiment is based on a plastic product with a density greater than that of water. In order to achieve the cleaning of impurities, such as Figure 1-3 As shown, it includes a floating fishing platform 1, the bottom of the outer walls on both sides of the floating fishing platform 1 are welded with a balancing floating plate 2, and the middle of the balancing floating plate 2 is rotatably installed with a rotating shaft 3, the bottom outer wall of the rotating shaft 3 is welded with a guide tube 4, and the top outer wall of the rotating shaft 3 is welded with a first bevel gear 5, the top of the first bevel gear 5 is vertically engaged and driven with a second bevel gear 6, and the axis of the second bevel gear 6 is connected to a first waterproof motor 7, the outer walls of the top two ends of the floating fishing platform 1 are welded with a limiting guide rail 10, and the inner wall of the limiting guide rail 10 is slidably inserted with a limiting guide block 11, a fixed plate 12 is welded between the limiting guide blocks 11, and an outer wall of one side of the fixed plate 12 is connected to an electric telescopic rod 13;

[0023] By setting balancing floating plates 2 on both sides of the bottom of the floating salvage platform 1, the overall stability of the salvage device can be effectively improved, and the center of gravity shift during the salvage process can be avoided to cause rollover. In addition, a guide tube 4 with a rotatable and adjustable angle is also provided at the bottom. The rotation and propulsion of the guide blades 9 can make the salvage structure conveniently adjust the driving direction and improve maneuverability.

[0024] A second waterproof motor 8 is fixed to the inner wall of the guide tube 4 by bolts, and the output shaft of the second waterproof motor 8 is connected to the guide blade 9. A rotating shaft 14 is rotatably mounted on the top outer wall of the fixing plate 12, and one end of the rotating shaft 14 is connected to a servo motor 15 via a coupling.

[0025] The outer walls of both ends of the rotating shaft 14 are welded with fixed blocks 16 distributed at equal distances, and the outer walls of the fixed blocks 16 are clamped and installed with connecting rods 17, and the outer walls of the ends of the connecting rods 17 are welded with salvage nets 18.

[0026] The first waterproof motor 7, the second waterproof motor 8, the electric telescopic rod 13 and the servo motor 15 are all connected to a PLC controller via signal lines, and the PLC controller is connected to an external power supply via wires;

[0027] In the process of salvaging floating objects, the servo motor 15 is used to drive the salvage net to rotate back and forth, so that the garbage floating on the water surface can be quickly salvaged and cleaned out. In combination with the pushing process of the electric telescopic rod 13, the salvage area can be effectively expanded and the cleaning effect can be improved. The flippable salvage net can quickly flip the garbage to make it fall off, avoiding the garbage sticking.

[0028] When this embodiment is used, the salvage structure is first assembled and connected to an external power supply for power supply. Then, the salvage structure is placed on the top of the primary sedimentation tank that needs to be salvaged and cleaned. Then, the PLC controller is used to control the rotation of the first waterproof motor 7 at the bottom to adjust the position of the bottom guide pipe 4, and at the same time, the second waterproof motor 8 at the bottom is started to drive the guide blade 9 to rotate, thereby realizing bottom thrust and allowing the salvage structure to move. During the movement, the servo motor 15 at the top is started, and the servo motor 15 is used to drive the rotating shaft 14 to rotate continuously and slowly, thereby driving the salvage net 18 to swing back and forth, first insert it into the water, and then rotate it. After the garbage is salvaged, the salvage net 18 is flipped to the top of the floating salvage platform 1. At this time, the garbage falls directly into the floating salvage platform 1 due to gravity, and during the salvage process, the salvage nets 18 on both sides of the top of the floating salvage platform 1 are staggered and salvaged from each other, so that rapid cleaning can be achieved.

[0029] Example 2:

[0030] A floating object salvage structure for a primary sedimentation tank, such as Figure 1-3 As shown, this embodiment makes the following supplements on the basis of embodiment 1: the salvage net 18 can rotate along the direction of the rotating shaft 14, and the rotation angle of the salvage net 18 is 0°-300°.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
