[0042] Embodiment 2

[0043] Since the filter cloth of the vacuum belt filter has a certain ductility, the filter cloth will have a certain length difference after being used for a long time due to the ductility, and the length difference of the filter cloth cannot be monitored in the calculation process of the integrator, which will affect the change of the measurement accuracy, and it is necessary to re-calibrate after running for a period of time to restore the weighing accuracy. Therefore, the present application provides an improved embodiment 2 as follows.

[0044] As shown in Figure 6 In addition to all the components of embodiment 1, the difference between the present embodiment and embodiment 1 is that the roller support 4 and the weighing mechanism 6 of the present application are connected by fastening bolts, and an adjusting knob 13 is sleeved on the screw rod of the fastening bolt between the roller support 4 and the weighing mechanism 6.

The bubble level 15 includes a long strip-shaped sealed cavity and a filling liquid in the cavity. The filling liquid has a bubble. Whether the bubble is located at the center of the length direction of the bubble level 15 is used to judge whether the roller support 4 is in a horizontal state, so as to adjust and correct, ensure that the roller support 4 is in a horizontal state, and improve the accuracy of the weighing measurement of the present application.

[0051] In order to ensure that the roller support 4 on both sides of the filter cloth 2 in the application is in a horizontal plane state, the application further comprises a light emitter 16 and a light receiver 17, the light emitter 16 and the light receiver 17 are arranged above the roller support 4, and the bottom of the light emitter 16 and the light receiver 17 extends into the roller support 4, and the light emitter 16 and the light receiver 17 can be removed when not in use. The light emitter 16 and the light receiver 17 are correspondingly arranged, the light receiver 17 receives the light emitted by the corresponding light emitter 16, and displays whether the information is received. The light emitter 16 and the light receiver 17 are arranged on one side of the roller support 4, and the corresponding light receiver 17 and the light emitter 16 are arranged on the other side of the roller support 4, through the cooperation of the two groups of light emitter 16 and light receiver 17, it can be seen whether the roller support 4 on both sides of the filter cloth 2 is in a horizontal plane state, so as to adjust and correct, improve the accuracy of the weighing measurement of the application.
