Problems solved by technology

[0009] Siphon type: After the liquid level drops, it will cause a great disturbance to the layered interface, which will affect the pipetting effect of the pipette
[0010] Sleeve type: The inner and outer cylinders of the sleeve connecting the discharge pipe are sealed by an "L"-shaped rubber sealing ring, which requires a large-power motor and a reducer, and it is difficult to keep in sync with the liquid level, so that the pipetting process cannot be carried out stably
The sealing friction resistance of the rubber sealing ring between the inner and outer cylinders of the sleeve is large, and it is particularly prone to the phenomenon that it cannot normally fall and rise due to the large resistance

Embodiment 1

[0043] Such as Figure 5-9The gravity separation removal device shown is mainly composed of a buoy actuator 1, a weir plate 2, and a linear self-supporting telescopic cylinder 3. The weir plate 2 is fixedly set on the outer wall surface of the upper end of the linear self-supporting telescopic cylinder 3, and forms an opening and closing water inlet weir with the bottom surface of the buoy actuator 1. Cylinder 3 consists of three sections of cylinders 3.1, 3.2 and 3.4 with different diameters to form a sliding sleeve type telescopic cylinder, adjacent cylinders can be slid relative to each other in sequence, such as the bottom end of the inner cylinder is equipped with a limit block 3.4, and the outer cylinder is equipped with a slider 3.3, Sealing element 3.5 is set on the outer wall of the joint of the inner and outer cylinders. The length and number of segments of the telescopic cylinder need to be designed according to the drop height of the liquid level. The weir plate ...

Embodiment 2

[0045] The device described in Embodiment 1 is adopted to carry out the gravity separation to take, and the specific technological process is as follows Figure 10 Shown: Settling, stratification - weir plate open - device and liquid level fall synchronously - minimum liquid level weir plate closed.

[0046] The first step of sedimentation or clarification: the solution undergoes physical and chemical reactions or biological activities in the sedimentation or clarification structure, and the inlet weir of the pipetting device is closed and kept at the upper limit of the liquid level (such as Figure 11 );

[0047] The second step is to stratify and open the pipetting device: the solution undergoes physical and chemical reactions or biological activities in the sedimentation or clarification structure, and after a certain period of stratification, the pipetting device moves downward and the water inlet weir is opened (such as Figure 12 ), the stratified supernatant slowly ent...

Abstract

The invention relates to a method and a device for water treatment. A device for transferring gravity separation substances mainly comprises a buoy execution mechanism, a weir plate and a linear self-operated telescopic cylinder, wherein the weir plate is fixedly sleeved on the outer wall surface at the upper end of the linear self-operated telescopic cylinder and forms a retractable water inlet weir crest with the bottom surface of the buoy execution mechanism, the upper end face of the linear self-operated telescopic cylinder is connected with the buoy execution mechanism, the linear self-operated telescopic cylinder is a sliding bush type telescopic cylinder with more than two sections, and a buoyancy generated by a floater equals to the gravity generated by the buoy execution mechanism, the weir plate and the linear self-operated telescopic cylinder in liquid. The execution mechanism of the device is simple, has low energy consumption, and is convenient to mount and repair. The weir plate adopts double-sealing precedence order, reliably prevents the disturbance of irregular fluid state entering the weir crest on the layered solution at the working initial stage of the device, and ensures the transfer of the layered supernatant. On the premise of ensuring sealing, the linear self-operated telescopic cylinder realizes synchronous rising or falling without an external force along with the liquid level, and ensures the stability and synchronous falling state of a layered level of the layered solution.

Description

1. Technical field: [0001] The invention relates to the field of environmental protection, in particular to a water treatment method, and also to water treatment equipment. 2. Background technology: [0002] Sedimentation or clarification process equipment is often used in the fields of water supply and sewage treatment, and oil-water separation. These process equipment are mainly used: the specific gravity of the polymer formed by adding physical and chemical agents and impurities in the water is greater than that of water; in the process of sedimentation or clarification, the stratification of the polymer or activated sludge and water is realized, and the purified water is in the upper layer. The polymer or activated sludge is in the lower layer, and then the upper layer water after stratification is removed by the pipetting device, so that the purified water can be discharged. In the same way, after the floating oil is separated, use a pipetting device to pipette and rec...
