Description

A sedimentation tank outlet tank cleaning device

technical field

The utility model relates to a cleaning device, in particular to a cleaning device for a water outlet tank of a sedimentation tank.

Background technique

The side wall of the outlet tank of the sedimentation tank of the sewage treatment plant is easy to breed algae, which affects the quality of the outlet water, especially in the season when the temperature is high, this phenomenon is particularly prominent. Conventional cleaning methods are mostly manual cleaning or mechanical cleaning devices.

Manual cleaning needs to be done with a long-handled brush. Since the cross-section of the water outlet is U-shaped, manual cleaning is acceptable for the parts that can be touched by the brush, such as the top of the water outlet. The parts that are easy to reach are very difficult to manually operate. Especially when the outlet tank is far away from the edge of the pool, it is necessary to hold a brush several meters long for operation. At this time, the effect of manual cleaning is very limited, and there are safety hazards such as falling into the water.

The mechanical cleaning device is mostly a dragging structure. The cleaning device is installed at the bottom of the rotating beam of the sedimentation tank, and a brush is installed on the cleaning device. When the rotating beam rotates slowly, the cleaning device is driven to clean all parts of the outlet tank. Because the brush is dragged forward at a very slow speed, most of the current mechanical cleaning devices have poor cleaning effects, such as poor cleaning effect at corners, algae hanging on the bristles and dragging, and algae growing in the bristles.

After careful analysis of the reasons, since the walls of the water tank are mostly cement or tile structures, the surface is smooth and flat, and the adhesion between algae or microorganisms and the wall of the water tank is not very strong. In theory, the brush is completely capable of cleaning. However, since the mechanical cleaning device is dragged by the rotating beam above the sedimentation tank, and the beam runs very slowly, the relative speed between the brush and the outlet tank is very low during the operation, forming a Although the brush is in good contact with the outlet tank, it only has the effect of "dragging" on the wall; moreover, due to the slow speed, it is easy to breed debris inside the brush.

Utility model content

Aiming at the actual situation of the sewage treatment plant, the utility model provides a cleaning device for the outlet tank of the sedimentation tank.

The technical solution of the utility model is: a sedimentation tank outlet tank cleaning device, including a traction chain, a stainless steel frame, positioning rollers, walking wheels, a horizontal rotating brush, a vertical rotating brush, and two geared motors. Traction chains, positioning rollers, walking wheels, horizontal rotating brushes, vertical rotating brushes, and geared motors are set on the stainless steel frame, and two geared motors drive the vertical rotating brushes and horizontal rotating brushes to rotate respectively.

The stainless steel frame is the main part of the cleaning device. The stainless steel frame is pulled forward by the traction chain. The positioning roller ensures that the distance between the cleaning device and the wall of the tank is maintained. The walking wheel makes the cleaning device move forward along the bottom of the tank. The positioning roller and the walking wheel Ensure that the main body of the cleaning device is stable and operates smoothly during the process of traveling and cleaning, and also ensure the flow area of the sink as much as possible, and ensure that the cleaning device does not deform due to the huge pressure difference between the inner and outer sides when it passes through the drain. All metal parts are It is made of stainless steel to avoid water pollution.

The utility model is dragged forward in the water outlet, and at the same time, the horizontal rotating brush and the vertical rotating brush are rotated under the drive of the deceleration motor, so the sides and bottom corners of the water outlet can be rotated and scrubbed, And by adjusting the speed of the motor, etc., different degrees of scrubbing can be carried out. This will make the cleaning work of the sewage tank of the sedimentation tank simple and easy, and achieve the purpose of reducing labor intensity, improving labor efficiency and improving cleaning effect.

Detailed ways

The details and working conditions of the specific equipment proposed according to the utility model will be described in detail below in conjunction with the accompanying drawings.

A sedimentation tank outlet tank cleaning device, including a traction chain 1, a stainless steel frame 5, a positioning roller 2, a traveling wheel 6, a horizontal rotating brush 8, a vertical rotating brush 3, a vertical gear motor 4, and a horizontal gear motor 9. Traction chain 1, positioning roller 2, walking wheel 6, horizontal rotating brush 8, vertical rotating brush 3, vertical gear motor 4, horizontal gear motor 9 are set on the stainless steel frame 5, and vertical gear motor 4 drives The vertical rotating brush 3 rotates, and the horizontal gear motor 9 drives the horizontal rotating brush 8 to rotate.

The stainless steel frame is the main part of the cleaning device, the stainless steel frame is pulled forward by the traction chain, the positioning roller 2 ensures that the distance between the cleaning device and the wall of the tank 7 is maintained, and the walking wheels 6 make the cleaning device move forward along the bottom of the tank. The positioning roller 2 and the walking wheel 6 ensure that the main body of the cleaning device is stable and runs smoothly during the process of traveling and cleaning, and can also ensure the flow area of the water tank as much as possible, and ensure that the cleaning device will not be damaged due to the huge pressure difference between the inner and outer water pressure when passing through the drain port. Deformation occurs, and all metal parts are made of stainless steel to avoid water pollution.

Before the cleaning device is used, it is connected to the bottom of the rotating beam of the sedimentation tank with a traction chain and connected to the power supply.

When in use, the rotating beam will drive the cleaning device forward. At this time, the horizontal rotating brush and the vertical rotating brush rotate respectively under the drive of the reduction motor, so as to achieve the purpose of scrubbing the water tank. In actual use, the motor speed can be determined according to the site conditions, so as to ensure that the equipment can run stably, and the debris on the corners, sides and other parts can be removed.

Since the brush is rotating, it will have the effect of "throwing away" during work, which will further increase the cleaning ability of the corners and seams of the sink.

Due to the different water flow directions in different parts of the tank, in order to ensure that the tangential direction of the brush rotation is the same as the water flow direction, the motor rotation direction can be set to automatically reverse the time according to the needs or the operation cycle, for example, the motor automatically reverses every 20 minutes.

Considering that the growth cycle of the algae in the water tank is not very long, and the growth cycle is different in different seasons, the operating time of the device can be set according to the needs of the season. For example, algae multiply quickly in summer, work 1.5 hours every other day, and the beam rotates about two times; work 1.5 hours every two days in winter, etc., to save electricity, save brushes, and prolong the service life of brushes.
