Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:
[0015] A cement tank as shown in the figure includes a tank body 3 and two groups of photoelectric detection units, that is, a first photoelectric detection unit 1 and a second photoelectric detection unit 2. The photoelectric detection unit includes a light-emitting tube and a light-receiving tube. The light-emitting tube and the light-receiving tube of the first photodetection unit are arranged horizontally and oppositely on the upper inner wall of the tank body; the light-emitting tube of the second photodetection unit is arranged above the light-emitting tube of the first photodetection unit, and the first photodetection unit The light receiving tube of the second photoelectric detection unit is at the same height as the light receiving tube of the first photoelectric detection unit, and the light emitting tube of the second photoelectric de...

The invention relates to a cement tank. Two groups of photoelectric detection units are used to correspond to different material level heights, so that before the light signal received by the light receiving tube of the first photoelectric detection unit is completely blocked, the cement tank can be inspected at a relatively fast speed. When adding cement, when the light receiving tube of the first photoelectric detection unit cannot receive the light signal at all, it indicates that the material level has reached a certain height. At this time, the filling speed is slowed down, and the material level is detected by the second photoelectric detection unit. When the light receiving tube of the second photoelectric detection unit cannot receive the light signal at all, stop filling the cement; in order to avoid the dust in the tank from adhering to the photoelectric tube and the light receiving tube and making them unusable, set them in the dustproof In the barrel, while using the gas to drive the shutter of the dustproof barrel to move, the gas washes the photoelectric tube and the luminous tube to prevent dust from accumulating on the two surfaces, so that the photoelectric detection unit can be used in the tank.
Description
technical field [0001] The invention relates to the field of cement storage and transportation equipment, in particular to a cement tank. Background technique [0002] In the process of transferring cement from the warehouse to the cement tanker, it is necessary to know the degree to which the cement fills the tanker. However, the method adopted in some enterprises is human observation or the use of weighbridges. Human observation is obviously inaccurate, and the weighbridge must be used when the weighbridge is laid in advance; if the radar level gauge is used, it is easy to be inaccurate for dusty cement, and the use and maintenance costs of the radar level gauge higher. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a cement tank using a photoelectric cell for material level detection, which is specifically realized by the following technical solutions: [0004] A cement tank, comprising a tank body ...
