Embodiment Construction

[0020] Such as Figure 1-5 As shown, the present invention includes a controller, a fixed door 5, a movable door 1 and a lifting device 3 for the movable door 1, the fixed door 5 and the movable door 1 are liquid-tightly bonded to each other, and the fixed door 5 and the movable door 1 are A number of panes are respectively provided, which are fixed door panes 6 and movable door panes 2. The panes 6 on the fixed door and the panes 2 on the movable door are mutually staggered in height. The above-mentioned dodge door 1 is connected. When the fixed door pane 6 and the movable door pane 2 do not match each other, the movable door 1 and the fixed door 5 of the present invention work together to cut off the liquid in the channel 4 . After the dodge door 1 is lifted, the panes between the two doors engage with each other (full engagement, partial engagement), such as figure 2 As shown, channel 4 is turned on.

[0021] The lower opening of the movable door pane 2 towards the fixe...

Abstract

The invention relates to a high-precision control gate for waste water backflow. The high-precision control gate for waste water backflow comprises a controller, a fixing gate, a movable gate and an elevating device of the movable gate. The fixing gate is attached to the movable gate in a mutual liquid-sealing manner. A plurality of panes are arranged on the fixing gate and the movable gate respectively. The panes on the fixing gate and the panes on the movable gate are staggered to each other in height. The elevating device is connected with the movable gate. The high-precision control gate for the waste water backflow is characterized in that the control gate further comprises a flow quantity sensor, a concentration sensor and an arithmetic unit, wherein the flow quantity sensor, the concentration sensor and the arithmetic unit are connected with the controller. According to the high-precision control gate for the waste water backflow, according to a result of arithmetic product of information value provided by the flow quantity sensor and the concentration sensor, inner backflow ratio of waste water treatment and opening degree of the control gate are adjusted.

Description

technical field [0001] The invention relates to a sewage treatment control gate, in particular to a large flow sewage treatment internal reflux ratio control gate capable of precisely controlling flow. Background technique [0002] In some sewage treatment processes, part of the sewage or sludge after the process is often refluxed to reduce the amount of flocculation agents and improve the mud-water separation effect. However, the return flow rate, that is, the reflux ratio control valve in sewage treatment often does not cooperate well. At the same time, there are still some large-sized debris in the fluid, which will block the above-mentioned valve. Contents of the invention [0003] In view of the above problems, the present invention provides a sewage treatment internal reflux ratio control gate with high control precision for adjusting the opening degree of the sewage treatment internal reflux ratio control gate according to the result of the product of the informatio...
