Description

Technical Field

[0001] The utility model relates to the technical field of material level detection, in particular to an asphalt tank inventory material level detection device. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive.

[0003] In the prior art, for example, Chinese patent CN218381173U discloses a material level detection device for storing building mortar raw materials, including a base plate, a support frame, a frame, a controller and a silo, wherein the support frame is fixedly connected to the top of the base plate, the frame is fixedly connected to the top of the support frame, the controller is fixedly connected to the outer wall of the support frame, the silo is fixedly connected to the inside of the frame, a weighing assembly is arranged at the bottom of the silo, and a material level detection assembly is arranged at the top of the silo, wherein the material level detection assembly includes a material level rod, a pressure plate, abutment plate and an observation window, and the material level rod is installed at the top of the silo. In this utility model, after the raw material is injected, the material level rod is pulled and then released, so that the material level rod automatically slides down in a natural state, and the bottom of the pressure plate abuts against the top of the raw material, thereby completing the detection of the raw material level inside the silo, and the material level height inside the silo can be further observed through the observation window, further reducing the detection error.

[0004] However, in actual use, the material level rod is completely placed above the raw materials when the silo is full, which makes the device too high and is dangerous when encountering a height-limited door during transportation. On the other hand, the raw materials cannot be effectively cleaned in time after use, which makes subsequent cleaning difficult.

[0005] Therefore, an asphalt tank inventory level detection device is proposed to solve the above problems. Utility Model Content
