DETAILED DESCRIPTION

[0014] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0015] Example:

[0016] This embodiment is a pH value detection mechanism for a dyeing machine reduction box, such as Figure 1 and Figure 2As shown, it includes a control box 1, a display screen 2, a detection probe 3, a lifting mechanism 4, a first temperature sensor 5, a cooling water circulation mechanism 6 and a detection bucket 7. The detection bucket 7 includes a cooling water area 71 and a detection liquid area 72. The detection probe 3 is arranged in the detection liquid area 72 through the lifting mechanism 4. The liquid inlet pipe 76 of the detection liquid area passes through the cooling water area 71 and is connected to the dyeing machine reduction box. The liquid outlet pipe 75 of the detection liquid area 72 is connected to the dyeing machine reduction box. The cooling water area 71 is connected to the cooling water circulation mechanism 6, and the first temperature sensor 5 is arranged in the detection liquid area. The control box is electrically connected to the display screen, the detection probe, the lifting mechanism, the first temperature sensor and the cooling water circulation mechanism respectively.

[0017] The detection bucket 7 is a container with an opening at the upper end. A partition 73 is welded in the container. The partition divides the internal space of the container into a cooling water area 71 and a detection liquid area 72. A cooling pipe 74 is provided on the partition. The cooling pipe is in a bolted rising shape. Both ends of the cooling pipe are connected to the cooling water area. A water inlet pipe 77 and a water outlet pipe 78 are provided on the cooling water area. The water inlet pipe is arranged near the lower end of the cooling pipe 74. The cooling water circulation mechanism includes a cooling water tank, a water pump, a second temperature sensor, a first solenoid valve and a second solenoid valve. The water pump is arranged in the cooling water tank. The water pump is connected to the water inlet pipe 77 of the cooling water area. The water outlet pipe of the cooling water area is connected to the cooling water tank. The first solenoid valve and the second solenoid valve are respectively arranged in the water inlet pipe and the water outlet pipe. The second temperature sensor is arranged in the cooling water area. The first solenoid valve, the second solenoid valve, the water pump and the second temperature sensor are all electrically connected to the control box. In this embodiment, the side walls of the cooling water tank and the cooling water area are provided with heat dissipation blocks.

[0018] The lifting mechanism comprises a Z-axis slide and a carrier plate arranged on the movable end of the Z-axis slide, the detection probe is arranged on the carrier plate, and the Z-axis slide is electrically connected to the control box.

[0019] The working principle of the pH value detection mechanism of the dyeing machine reduction box in this example is as follows: the liquid in the dyeing machine reduction box flows between the reduction box and the detection liquid area through the liquid inlet pipe 76 and the liquid outlet pipe 75. The high-temperature liquid in the detection liquid area will heat the cooling water in the cooling pipe. After the cooling water in the cooling pipe is heated, it rises along the cooling pipe, so that the cooling water in the cooling water area and the cooling pipe circulates to ensure the cooling effect of the cooling pipe. The detection probe is used to detect the pH value of the liquid in the detection liquid area. During the detection, the temperature of the liquid in the detection liquid area is detected by the first temperature sensor. When the liquid temperature is lower than the threshold value, the control box controls the lifting mechanism to drive the detection probe into the area in the middle of the cooling pipe to detect the pH value and display the pH value on the display screen. At the same time, if the first temperature sensor detects that the temperature is too high, the lifting mechanism causes the detection probe to leave the detection liquid area. At the same time, the control box controls the operation of the cooling water circulation mechanism. When the cooling water circulation mechanism is running, the cooling water in the cooling water tank is discharged into the cooling water area under the action of the water pump. Because the water inlet pipe is close to the lower end of the cooling pipe, when the cooling water is discharged, a water flow will be formed to accelerate the speed at which the cooling water in the cooling water area enters the cooling pipe, thereby improving the cooling efficiency of the cooling pipe. In addition, the cooling water circulation mechanism will also operate when the second temperature sensor detects that the temperature in the cooling water is higher than the threshold value to prevent the cooling water temperature in the cooling water area from being too high.

[0020] In this example, the control box obtains the data of the first temperature sensor, the second temperature sensor and the detection probe, and controls the first solenoid valve, the second solenoid valve, the lifting mechanism, the water pump and the display screen, all of which are existing technologies.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
