[0037] On the basis of the above-mentioned embodiment, in particular, the sizing tank detection device can remove the sensor component C, the mounting tube 6, and the rubber ring 8 and set a scale on the observation mirror, so that the operator can judge whether the sizing liquid needs to be replenished through observation.

[0038] The above implementation modes are only several typical combinations of the present solution. The implementation modes described in the implementation modes can be combined arbitrarily without departing from the protection scope of the present solution.

[0039] Working method:

[0040] 1) Setting a sizing liquid concentration detection device;

[0041] 2) The standard buoy 3 moves between the upper filter screen 2 and the lower filter screen 4 in the buoy guide cylinder 1;

[0042] 3) When starting the measurement, set the standard buoy 3 and add a standard mass block to it so that its density is 1g / cm higher than the density of the sizing solution. 3, placing the sizing tank concentration detection device in the sizing tank, the sizing liquid always does not pass through the upper filter screen 2;

[0043] 4) The standard buoy 3 is always completely immersed in the sizing liquid. According to the buoyancy principle F 浮 =ρgV 排 It can be seen that the volume of liquid displaced by the standard buoy 3 is always equal to its own volume; the concentration of the sizing liquid in the sizing pool is higher than the set sizing concentration by 1g / cm 3 When the buoyancy of the standard buoy 3 is greater than its own gravity, the standard buoy 3 floats below the upper filter screen 2; when the sizing liquid concentration in the sizing pool is less than or equal to the set slurry replenishment concentration, the buoyancy of the standard buoy 3 is less than its own gravity, and the standard buoy 3 descends until it is above the lower filter screen 4.

[0044] The detection principle of this embodiment will be explained below from the operation situation during actual use:

[0045] Specifically, the device is installed inside the sizing tank, and the sizing liquid never passes through the upper filter screen 2;

[0046] The volume V of the liquid displaced by the standard buoy 3 in the sizing liquid 排 Always remain the same;

[0047] Before use, the concentration of the sizing solution to be tested must be determined. The interior of the standard buoy 3 is a hollow structure. According to the concentration of the replenishment solution, standard mass blocks can be added or removed from the interior. Each block increases or decreases 0.5g / cm for the standard buoy 3. 3 ; Set the standard float density to be 1-2g / cm greater than the slurry concentration required for slurry replenishment 3 ;

[0048] When the device is running in the sizing tank, when the concentration in the sizing liquid is greater than the concentration of the standard buoy 3 (set sizing concentration), the standard buoy 3 floats below the upper filter 2 due to the buoyancy; when the concentration in the sizing tank is less than the standard buoy concentration 3 (set sizing concentration), the standard buoy 3 sinks above the lower filter 4 due to gravity;

[0049] During the sinking process of the standard buoy 3, the sensor 9 will be triggered, and the sensor 9 will transmit the signal to the controller, that is, the sizing tank will start to be replenished. When the concentration in the sizing tank is greater than the standard buoy 3, the standard buoy 3 will float up, and the system will delay the replenishment closing time for 2 minutes;

[0050] The device can make the lifting rod 10 with scale rise or fall by rotating the rotating rod 11 in the sensor assembly C, and further make the sensor 9 rise or fall, so as to adjust the detection sensitivity of the device.

[0051] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
