Description

Technical Field

[0001] The utility model relates to the technical field of water quality treatment devices, in particular to a water quality treatment device for a clarifier in a water plant. Background Technique

[0002] The clarifier is a technology widely used in the field of water treatment. The clarifier is a water purification structure that uses the sludge accumulated in the pool to contact and adsorb the impurity particles in the raw water to achieve rapid separation from clear water. It can give full play to the role of the coagulant and improve the clarification efficiency. In current sewage treatment, the flocculation process and the sedimentation process are often integrated. The flocculation process includes three processes: 1. Coagulation stage, 2. Flocculation stage, and 3. Sedimentation stage. After these three stages, the flocs and clarified water can be clearly stratified. However, during the sinking process of the flocs, they are likely to adhere to the stirring device. A large amount of flocs accumulated on the stirring device for a long time affects the normal operation of the stirring device, causing the motor to operate overload, and even causing the phenomenon of motor burnout.

[0003] To solve the above technical problems, Chinese Patent No. CN106823495A in the prior art discloses a high-density mechanical stirring clarifier, which includes a clarifier body. A sludge scraping plate is provided inside the clarifier body. An outlet for discharging sludge is provided at the bottom of the clarifier body. The clarifier body is connected to a water storage tank through a connecting pipe. It also includes a power supply, a control unit, a sensor circuit, a lifting circuit, a driving circuit, and a pumping circuit. The control unit is electrically connected to the power supply.

[0004] Although the above prior art solution can prevent the sediment from adhering to the stirring device, when adding polyaluminum chloride reagent to improve water quality, it still requires the staff to take out and weigh the required reagent batch by batch according to the actual water volume to be treated each time, and then manually sprinkle it into the clarifier, which increases the labor intensity of the staff and affects the work efficiency.

At this time, the angle of the pulling ring is deflected and hooked on the hanging rod 22 for temporary positioning. Then the positioning frame 20 can be removed together with the first motor 7 and the discharge cover 6. Subsequently, the inside of the discharge cylinder 5 and the circulation holes are cleaned.

[0029] The implementation principle of a water treatment device for a clarifier tank in a water plant according to an embodiment of the present application is as follows: a bag of medicine is poured into the inner side of a feed hopper for storage in advance, and then the first motor 7 is started to drive the fixed plate and the scraper 8 to rotate forward or reversely. When the scraper 8 is offset from the upper flow hole, the medicine particles leak down, and the medicine particles on the inner side of the chamber composed of the two groups of scrapers 8 and the discharge barrel 5 seep out through the gaps generated when the scraper 8 is offset from the lower through holes and fall through the discharge pipe. The size of the gap can be adjusted by the staff by controlling the rotation angle of the first motor 7. The falling medicine particles fall to the top surface of the rubber pad 13 and the impact force is initially absorbed. The buffer plate 12 also slides on the inner side of the buffer groove, and cooperates with the limit block 14 to compress the airbag 11 and the first spring to retract and unload the force again. After the falling medicine particles increase to a certain weight, the torsion spring 10 is squeezed and retracted, and the rotating plate 9 is synchronously The rotation makes the inclination angle larger, and the pharmaceutical particles will slowly slide onto the guide plate to prevent a large number of pharmaceutical particles from falling too fast and directly hitting the pressure sensor 23. The pressure sensor 23 can detect the total weight of the pharmaceutical on its top surface. If the weight meets the standard, the material is stopped, and then the second motor starts to drive the reciprocating screw 15 to rotate, and cooperates with the adjustment groove and the adjustment plate 16 to drive the brush on the sweeping plate 17 to sweep the pharmaceutical particles to the port of the discharge pipe 18, and finally discharge them into the clarification tank body 1. The pull ring is buckled to drive the sliding column to move, so that the second spring is stretched, and the sliding column gradually disengages from the sliding hole inside the positioning frame 20. At this time, the pull ring is deflected at an angle and hung on the hanging rod 22 for temporary positioning. Then the positioning frame 20 can be connected to the first motor and the discharge cover 6 7 and removed together, and then the inner side and the flow hole of the discharge barrel 5 are cleaned.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
