Pump circulation device for intelligently homogenizing temperature of asphalt heating tank

Abstract

The invention belongs to the technical field of asphalt heating tanks, particularly relates to a pump circulation device for intelligently homogenizing the temperature of an asphalt heating tank, and aims at solving the problems that an asphalt pump nozzle of an existing asphalt heating tank pump circulation device is fixedly arranged, asphalt is difficult to uniformly spray out, the activity of the asphalt in a tank body is poor, and the asphalt cannot be uniformly sprayed out. According to the scheme, the asphalt heating device comprises an asphalt heating tank, the top of the asphalt heating tank communicates with a feeding pipe, communicating holes are formed in the two sides of the asphalt heating tank correspondingly, the same heat conduction oil pipe is fixedly installed in the two communicating holes, and flange plates are fixedly installed at the two ends of the heat conduction oil pipe correspondingly; and an asphalt circulating pump is fixedly mounted at the bottom of one side of the asphalt heating tank. The asphalt spraying pipe can be driven to rotate so as to improve the distribution uniformity of sprayed asphalt, the stirring rod can be driven to reciprocate up and down, meanwhile, the asphalt is uniformly and efficiently stirred through reciprocating rotation, and the heating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt heating tanks, in particular to a pump circulation device used for intelligent temperature homogenization of asphalt heating tanks. Background technique [0002] Asphalt or semi-finished asphalt is generally a highly viscous liquid, and the fluidity in the heating tank is insufficient. The asphalt in the tank often has problems such as heating dead corners, local overheating and long heating time, which cannot effectively achieve the temperature homogenization of the heated asphalt. , thereby affecting the quality and heating efficiency of asphalt finished products. After searching, the Chinese patent with the authorization announcement number CN105273736B discloses a pump circulation device for the temperature homogenization of the asphalt heating tank, including the asphalt heating tank body, which is provided with an asphalt inlet, an asphalt outlet, and an exhaust port. A heating device is ar...
