no. 1 example

[0036] In the following description of the water treatment tank, only the structure closely related to the present invention will be described. For other structures in the water treatment system, such as the dosing device, the sedimentation device placed in the sedimentation tank, etc., those skilled in the art can refer to the current There is technology to implement it. In the water treatment system, at least the flocculation tank and the sedimentation tank need to be discharged. The level control system of the present invention can be used in the flocculation tank and / or the sedimentation tank, and can also be used in other tanks that need to be discharged. The sludge discharge of the sedimentation tank is taken as an example to illustrate.

[0037] see figure 1 , the water treatment tank has a sedimentation area 1 and a level control system, the level control system has a control unit 2, a lifting device 3, a detection unit 4, a mud valve 5 and an air valve 6, and the lif...

no. 2 example

[0045] see Figure 4 and Figure 5 , Figure 5 yes Figure 4 , and the detection unit 4 is omitted. The difference between this example and the previous example is the structure of the lifting device 3 in the level control system. The upper section of the lifting rod 31 is a rack 313, and a stepper The motor 36 drives the reduction box 33.

no. 3 example

[0047] see Figure 6 and Figure 7 , Figure 7 yes Figure 6 The left side view of , and omit the detection unit 4 and the stepping motor 36, the difference between this example and the first example is also the structure of the lifting device 3 in the level control system, the upper section of the lifting rod 31 is a worm 314, which adopts A stepping motor 36 drives the worm gear 37, and the lifting rod 31 is driven by the worm gear 37 to lift.

Abstract

The invention discloses a material level control system, a control method and a water treatment tank, and relates to the technical field of water purification treatment. The material level control system comprises a control unit and a detection unit, the control unit receives signals of the detection unit, a lifting device comprises a lifting rod, and the detection unit is fixed to the lower end of the lifting rod. The control unit is used for controlling the lifting device according to a sludge level signal sent by the detection unit, so that the detection unit is lifted. The method comprisesa setting step, a tracking ascending step and a tracking descending step. A water treatment tank adopts the material level control system. The system has the advantages of accurate monitoring, waterquality improvement and cost reduction.

Description

technical field [0001] The invention relates to water treatment and purification equipment and a control system, in particular to a material level control system, a control method and a water treatment pool. Background technique [0002] Water treatment is a process of removing impurities, ammonia nitrogen, COD, total phosphorus, total nitrogen, and ammonia nitrogen in raw water through physical, chemical, and microbial methods. During water treatment, impurities in raw water are formed through flocculation, precipitation, and other treatment steps. The impurity clusters will settle to the bottom of the water treatment tanks such as the flocculation area and the sedimentation area to form sludge. When the sludge accumulates to a certain thickness, the sludge must be discharged through the sludge discharge device connected to the bottom of the tank to prevent sludge Leading to excessive water turbidity. [0003] In order to ensure that the sludge level is within an appropria...
