Description

Technical Field

[0001] The utility model relates to the technical field of pH detection, in particular to a stirrable pH detector. Background Art

[0002] pH testing is to detect the acidity and alkalinity of solutions and objects. pH meter is an important tool for measuring and reacting the acidity and alkalinity of solutions. There are various models and products of pH meters, and the display mode also has two options: pointer display and digital display. However, no matter how the type of pH meter changes, its working principle is the same, and its main body is a precision potentiometer. The current pH detection head is not convenient for detecting test tube solutions at different depths. It is necessary to sample the solution in the test tube first, which is cumbersome to operate. In the prior art, when the pH detector is used for detection, it is first fully mixed by a stirring device before detection. In the prior detection method, it is first stirred and then the detector is inserted into the solution to be tested. It takes a long time to detect accurate data, which makes the operation more difficult. Even many solutions need to be stirred while inserting electrodes during detection. For example, when the acidometer measures the pH of the solution, it is necessary to insert the detection electrode into the solution to be tested while stirring. When a person is operating, he needs to stir and insert the detection meter into the test liquid at the same time. In the prior pH detection, one hand is required to stir and the other hand is required to insert the detection electrode into the solution to be tested. The operation is cumbersome, resulting in inaccurate data detection and the like. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem solved by the utility model is a stirrable pH detector, which solves the problem of cumbersome operation when the prior art stirs and detects at the same time.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a stirrable pH detector, characterized in that: it includes a workbench, a lifting device is fixedly arranged on the workbench, and a support column with a hollow structure is fixedly arranged on the lifting device; a lifting rod is arranged inside the support column, and the lifting rod is drivingly connected to the lifting device; an adjusting device is arranged on the support column, and a fixing seat is fixedly arranged at one end of the adjusting device away from the adjusting rod; a fixing ring is fixedly arranged on the fixing seat; a receiver is arranged at the upper end of the fixing ring; a detection electrode is arranged at the lower end of the fixing seat, and the detection electrode is fixedly connected to the receiver; a gear bearing is arranged at the connection between the detection electrode and the fixing seat, and a driving device is arranged on one side of the gear bearing, and the driving device is meshingly connected with the gear bearing; a stirring rod is arranged at the lower end of the gear bearing, and there are multiple stirring rods, and the stirring rods are arranged at the lower end edge position of the gear bearing; a controller is arranged on one side of the receiver, and the controller is fixedly connected to the base, and the controller is connected to the receiver line.

[0005] The technical principle of this solution is: the controller supports the device to control the lifting and lowering of the lifting rod, so that the detection electrode and the stirring rod set on the fixed seat can be extended and retracted into the solution to be tested. During the detection, the driving device rotates to control the rotation of the gear bearing, thereby driving the rotation of the stirring rod on the gear bearing. After that, the lifting rod is lowered to extend the detection electrode and the stirring rod into the solution to be tested for stirring and detection at the same time. The stable data obtained from the detection is transmitted to the receiver and then to the controller through the receiver. The operation is convenient, the detection and stirring are carried out at the same time, the detection data is accurate, and the detection time can also be shortened.

[0006] The beneficial effects of this solution are: by setting a rotatable stirring rod around the detection electrode, the detection electrode and the stirring rod can be simultaneously extended into the solution to be tested when testing the solution, which is simple to operate. At the same time, the lifting and lowering of the lifting rod is controlled by the supporting device, making the lifting and lowering more intelligent and the lifting position more accurate; at the same time, the adjustment device can also be adjusted horizontally, so that the device can be adjusted horizontally up and down, with a wide adjustment range, and multiple solutions to be tested on the workbench can be tested at the same time without moving the solutions to be tested. The detection efficiency is high.

[0007] Furthermore, a supporting ring is provided at the connection between the adjusting device and the support column. The supporting ring is fixedly connected to the lifting rod through a limiting groove arranged on the support column. The supporting ring is slidably connected to the support column. The supporting ring can ensure good stability when the adjusting device slides up and down during lifting, and will not cause the adjusting device to tilt due to uneven force on the side where the adjusting device contacts the support column, thereby causing the adjusting device and the support column to be tilted and locked.

[0008] Furthermore, a locking device is provided on one side of the adjusting device, and the locking device is cooperatively connected with the adjusting device. The adjusting device is locked by the locking device, so that the adjusting device has good stability after extension and retraction.

[0009] Furthermore, a sensor is arranged on the workbench, and a sensor is arranged at the bottom of the fixed seat directly above the sensor. The sensor is electrically connected to the sensor, and the sensor and the sensor are both electrically connected to the controller. The sensor and the sensor are arranged correspondingly, and the distance between the fixed seat and the workbench is monitored by the sensor and the sensor, so as to ensure that when the solution is detected, the detection electrode can extend to the bottom without touching the bottom, and the safety is good.

[0010] Furthermore, a rolling bearing is provided at the connection between the detection electrode and the fixed seat, and the rolling bearing is connected with the gear bearing. The roller bearing can ensure that when the gear bearing rotates to drive the stirring rod to rotate for stirring, the gear bearing and the rolling bearing are connected in a rolling manner, thereby reducing the jitter of the detection electrode.

[0011] Furthermore, the driving device is electrically connected to the controller, and the controller can control the rotation speed of the driving device to adjust the stirring speed of the rotating rod. The stirring speed can be adjusted for different solutions to be tested, and the practicability is good. BRIEF DESCRIPTION OF THE DRAWINGS
