The applicant finds that the reasons for causing the false alarm of the photoelectric tube at the blocking position mainly exist in two aspects: (1) During the process that the material enters the metering tube, part of the material splashes on the photoelectric tube, so that the photoelectric tube is shielded to generate false alarm; (2) In the production stage of the equipment, the photoelectric tube is arranged in the area around the material scattering path, so that the material to be fed blocks the photoelectric tube at the blocking position, and the photoelectric tube is in false alarm, so that current interruption occurs.
For the above reasons, the applicant has provided in the present invention a method of calculating the installation area of a detection device, wherein the detection device can be used to detect the height of a material in an installation body, and when the height of the material reaches the height of the detection device, the detection device is triggered to emit a signal. Taking a detection device as an example of a material blocking position photoelectric tube arranged on the metering tube, when the height of a material reaches the height position of the material blocking position photoelectric tube, the material blocking position photoelectric tube is blocked by the material to generate a signal, so that the material feeding device for feeding the metering tube stops feeding.
