The applicant finds that the reason for causing the false alarm of the photoelectric tube of the material blocking level at present mainly has two aspects: (1) when the materials enter the metering pipe, part of the materials splash on the photoelectric tube, so that the photoelectric tube is shielded to generate false alarm; (2) in the equipment production stage, the photoelectric tube is arranged in the area around the material scattering path, so that the feeding material blocks the photoelectric tube at the material blocking position, the photoelectric tube gives a false alarm, and the current is cut off.
For the above reasons, the applicant provides a method for calculating the installation area of a detection device, wherein the detection device can be used for detecting the height of the material in the installed body, and when the height of the material reaches the height of the detection device, the detection device is triggered to send out a signal. Taking the detecting device as a material blocking position photoelectric tube installed on the metering tube as an example, when the height of the 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 device for conveying the material to the metering tube stops feeding the material.
Specifically, as shown in fig. 2, the method for calculating the installation area of the detection device may include:
s1, according to the initial speed of the material, constructing a motion equation of the material in the installed body, and obtaining the motion trail of the material in the installed body, wherein the motion equation is a relational expression between the vertical displacement and the horizontal displacement of the material in the installed body.
S2, projecting the motion track of the material to the installation side of the installed body to obtain a first projection area; specifically, the projection here is a vertical projection.
And S3, determining the installation area of the detection device according to the first projection area, wherein the installation area is an area except the first projection area on the installation side surface of the installed body.
Through setting up detection device in the region outside the movement track of material, can avoid detection device to take place the erroneous judgement because of the material in the motion shelters from, improve detection device's accuracy nature.

Figure BDA0002893193870000072
wherein, the rated rotating speed r, the rated frequency f, the reduction ratio i and the diameter d of the chain wheel are fixed values, and the circumferential ratio pi is also fixed, therefore, the cabinet-out speed V and the set frequency fsetIs in direct proportion. That is, the determination of the draw-out speed V may be calculated based on the operating parameters of the cabinet.
