[0006] Preferably, the surface of the compression plate is rotatably connected to a rotating shaft, and a plurality of elimination blades are annularly distributed on the outer wall surface of the rotating shaft. The arrangement of the elimination blades has the effect of breaking up and eliminating water bubbles.

[0007] Preferably, a cylinder is fixedly mounted on the top surface of the processing barrel, a first motor is fixedly mounted on the output end of the cylinder, and the output end of the first motor is fixedly connected to the rotating shaft. The cylinder is provided to drive the first motor to move, and the first motor is provided to drive the rotating shaft to rotate.

[0008] Preferably, a filter device is provided on the side of the filter box, the filter device comprising a U-shaped bracket fixedly mounted on the side of the filter box, a threaded rod rotatably connected between the inner walls of both ends of the U-shaped bracket, a second motor fixedly mounted on the top surface of the U-shaped bracket, an output end of the second motor being fixedly connected to the threaded rod. The second motor serves to drive the threaded rod to rotate.

[0009] Preferably, a groove is formed on the inner wall surface of the vertical end of the U-shaped bracket, and a movable plate is threadedly connected to the surface of the threaded rod. The arrangement of the threaded rod drives the movable plate to move inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, by providing an elimination device, when it is necessary to defoam the water sample inside the processing barrel, the cylinder is first started, and the cylinder starts to drive the first motor to move downward. The downward movement of the first motor drives the rotating shaft to move downward. The downward movement of the rotating shaft drives the compression plate to move downward. The downward movement of the compression plate drives the L-shaped plate to move downward inside the vertical groove. When the compression plate drops to above the liquid surface, the cylinder is closed. At this time, the foam passes through the compression hole on the compression plate. The diameter of the compression hole is smaller than the diameter of the foam, thereby squeezing the foam or dispersing it into foam with a smaller diameter, thereby facilitating defoaming. Then, the first motor is started, and the first motor starts to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the defoaming blade to rotate above the compression plate, directly contacting the foam passing through the compression hole. The shear force generated by the rotation directly breaks the foam, completing complete defoaming. The defoamed water flows back into the liquid in the processing barrel through the compression hole. Through the cooperation of the above structure, the device can use the combination of two defoaming methods to quickly eliminate the foam inside the processing barrel, thereby improving the accuracy of the detection of water samples inside the processing box.

[0013] 2. In the utility model, by setting a filtering device, when it is necessary to filter the water sample input into the processing box, the second motor is started first, and the second motor starts to drive the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move downward inside the vertical slot. The movable plate moves downward inside the vertical slot, driving the connecting rod to move downward. The connecting rod moves downward and drives the filter screen to move downward. The filter screen moves downward so that it can enter the interior of the filter box through the through slot. When the filter screen is located inside the filter box, the second motor can be turned off. Through the cooperation of the above structure, the filter screen can enter the interior of the filter box, so that the filter screen can be used to filter the water sample input into the processing barrel in advance, thereby further enhancing the accuracy of subsequent water sample testing.
