Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detectors, and particularly relates to a water quality detector for a clarifier. Background Technique

[0002] A clarifier is a device specifically used for the coagulation treatment of water, aiming to remove suspended solids and colloids in water. It is a structure that integrates the flocculation reaction process and the clarification and separation process, and plays an important role in the purification treatment of water.

[0003] For example, the Chinese patent with the publication number CN220438319U discloses a water quality detector, including a connecting plate. The upper surface of the connecting plate is fixedly connected with a U-shaped plate. An fixing plate is arranged inside the U-shaped plate, and a driving motor is fixedly embedded on the upper surface of the U-shaped plate. Through the cooperation of the driving motor and the external thread screw rod, it is convenient for the external thread screw rod to rotate inside the rolling bearing, while the internal thread moving block rotates with the external thread screw rod to move up and down, and it is convenient to drive the positioning block to move inside the positioning port. At this time, through the cooperation of the positioning block and the positioning port, the rotation of the internal thread moving block can be prevented, and the fixing plate can move smoothly. At the same time, according to the thrust of the fixing plate, it is convenient for the water quality detection rod to be inserted into the sampling bucket for detection work. Then, through the cooperation of the water quality detection rod, the controller and the water quality display, it is convenient to detect the water, and the detection method has high accuracy and is beneficial for current personnel to use.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when the above device detects the water quality, it does not filter the suspended particulate matter in the water. The suspended particulate matter in the water sample will directly enter the detector, and these particulate matters may affect the detection result. At the same time, the water is not stirred during the detection. If there are components in the water sample that are prone to precipitation or stratification, insufficient stirring may cause these components to precipitate or stratify in the detector, further affecting the accuracy of the measurement result. In view of this, we propose a water quality detector for a clarifier. Content of the Utility Model

[0006] The purpose of the utility model is to provide a water quality detector for a clarifier to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a water quality detector for a clarifier, including:

[0008] A detection tank, the top of the detection tank is fixedly installed with a water inlet pipe, the top of the water inlet pipe is fixedly installed with a filter housing, a sliding frame is inserted and installed inside the filter housing, and a filter screen is fixedly installed inside the sliding frame;

[0009] A limiting component, which is located inside the filter housing and is used to fix the position of the sliding frame;

[0010] A power chamber, which is opened in the detection tank. A gear is rotatably installed in the power chamber. A rotating shaft is fixedly installed at the lower end of the gear. The lower end of the rotating shaft penetrates through the power chamber and extends into the inner cavity of the detection tank. The rotating shaft is rotatably connected to the power chamber and the detection tank. A plurality of stirring blades are fixedly installed on the rotating shaft. A water quality detection tube is fixedly installed on one side of the rotating shaft in the inner cavity of the detection tank. A discharge pipe is fixedly installed at the bottom of the detection tank. A valve is fixedly installed on the discharge pipe;

[0011] A driving component, which is located inside the detection tank and is used to drive the gear to rotate reciprocally.

[0012] In this technical solution, when it is necessary to detect the water in the clarifying tank, first pour the water sample into the filter housing. Subsequently, the suspended particulate matter in the water sample will be filtered by the filter net and stay on the filter net. The filtered water sample enters the detection tank through the filter net and the water inlet pipe. By means of the provided driving component, the gear can be driven to rotate reciprocally. The reciprocating rotation of the gear drives the rotating shaft and the stirring blades to rotate reciprocally. The plurality of stirring blades can uniformly stir the water sample in the detection tank, and there will be no precipitation or stratification phenomenon. After the stirring is completed, turn off the motor, and then detect the water sample in the detection tank through the water quality detection tube. Finally, open the valve on the discharge pipe so that the detected water sample in the detection tank can be discharged to the outside through the discharge pipe;

[0013] When it is necessary to clean the suspended particulate matter accumulated on the sliding frame, through the provided limiting component, the operator can pull the sliding frame and the filter net outwards. At this time, the suspended particulate matter on the sliding frame can be cleaned. After the cleaning is completed, insert the sliding frame into the filter housing. Through the provided limiting component, the position of the sliding frame can be fixed, which is convenient for the installation and disassembly of the sliding frame and further convenient for cleaning the suspended particulate matter on the filter net, and the filter net will not be blocked.

[0014] In the above technical solution, further, the limiting component includes:

[0015] A sliding groove, which is opened in the filter housing. Two sliding rods are slidably installed in the sliding groove. The two sliding rods are respectively located on the upper and lower sides of the sliding frame. One side of the two sliding rods close to each other is inserted and matched with the sliding frame. A plurality of springs fixed to the inner wall of the sliding groove are fixedly installed on one side of the two sliding rods away from each other;

[0016] An elliptical cylinder is rotatably installed in the sliding groove and located between two sliding rods. The circumferential side wall of the elliptical cylinder contacts the two sliding rods. One end of the elliptical cylinder is fixedly installed with a rotating column.

Two ends of the torsion spring are respectively fixed to the inner wall of the sliding groove and the elliptical cylinder. The rotating column is rotatably connected to the sliding groove.

[0017] In this technical solution, when it is necessary to clean the suspended particulate matter accumulated on the sliding frame, first rotate the rotating column and the elliptical cylinder forward. At the same time, the torsion spring is twisted. The elliptical cylinder will squeeze the two sliding rods to slide and move away from each other. At the same time, several springs are squeezed and contracted. When both sliding rods are disengaged from the sliding frame, the handle can be pulled to drive the sliding frame and the filter net to be pulled outwards. At this time, the suspended particulate matter on the sliding frame can be cleaned. After the cleaning is completed, the sliding frame is inserted into the filter housing. Then the person releases the rotating column. Under the action of the torsional force of the torsion spring, the elliptical cylinder and the rotating column will rotate in the reverse direction. Then the elliptical cylinder no longer squeezes the two sliding rods. Under the action of the rebounding force of several springs, the two sliding rods slide and approach each other. Then both sliding rods are inserted into the sliding frame, and the position of the sliding frame can be fixed, which is convenient for the installation and disassembly of the sliding frame, further convenient for cleaning the suspended particulate matter on the filter net, and the filter net will not be blocked.

[0020] In this technical solution, when it is necessary to detect the water in the clarifier, first pour the water sample into the filter housing. Subsequently, the suspended particulate matter in the water sample will be filtered by the filter net and stay on the filter net. The filtered water sample enters the detection tank through the filter net and the water inlet pipe. Then, start the motor. The motor is powered on and drives the disc to rotate. The disc drives a number of second toothed blocks, the rotating disc and a number of first toothed blocks to rotate. When a number of first toothed blocks engage with the gear, the gear will rotate forward. When a number of first toothed blocks no longer engage with the gear, a number of second toothed blocks will engage with the gear, and the number of second toothed blocks drives the gear to rotate in the reverse direction. The reciprocating rotation of the gear drives the rotating shaft and the stirring blades to reciprocate. A number of stirring blades can evenly stir the water sample in the detection tank, and there will be no precipitation or stratification phenomenon. After stirring is completed, turn off the motor, and then detect the water sample in the detection tank through the water quality detection pipe.
