Problems solved by technology

[0003] During road maintenance, the asphalt in the tank is pumped out with a pump. In order to avoid asphalt pollution, the pump and pipeline are installed outside the asphalt tank. Since the asphalt solidifies at low temperature and loses fluidity, an additional heating device is required to heat and keep the asphalt warm. To maintain its fluidity, the heating device not only greatly increases the manufacturing cost and use cost of the asphalt pavement maintenance vehicle, but also increases the weight of the asphalt pavement maintenance vehicle

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, and the content of the present invention is not limited to the following embodiments.

[0021] The self-heating type top-mounted pump valve system in the tank provided by the present invention has a structure such as figure 1 As shown, the motor 2, the pump 19 driven by the motor 2 and the asphalt pipe communicated with the pump 19 are included. The motor 2, the pump 19 and the asphalt pipe are all installed on the top of the asphalt tank 11, and the motor 2 passes through the support pipe 9 and the support pipe. The flange 14 is installed on the top of the asphalt tank 11 and is located outside the asphalt tank 11, and the support pipe 9 and the support flange 14 are connected by a threaded fastener 6;

[0022] Both the pump 19 and the asphalt pipe are installed on the top of the inner cavity of the asphalt tank 11 through the supporting cavity 12. The...

Abstract

The invention relates to a self-heating overhead in-tank pump valve system which comprises a motor, a pump and an asphalt pipe. The motor is mounted at the top of an asphalt tank through a supportingtube and a supporting flange and located outside the asphalt tank, and the supporting tube and the supporting flange are connected through a threaded fastener. The pump and the asphalt tube are mounted at the top of an inner cavity of the asphalt tank through a bearing cavity. The bearing cavity is provided with a flange edge and is fixed on the top inner wall of the asphalt tank through a bolt. An output shaft of the motor is connected with an input shaft of the pump through a coupling. An inner cavity of the supporting tube is filled with a heat insulation material and is internally providedwith fan blades, and the heat insulation material covers the coupling. According to the self-heating overhead in-tank pump valve system, the motor, the pump and the asphalt tube are all mounted at the top of the asphalt tank, and the pump and the asphalt tube are arranged in a built-in mode; the asphalt tank is usually not fully filled, and the pump and the asphalt tube are packed in the bearingcavity and located at the top of the inner cavity of the asphalt tank, so that the pump and the asphalt tube are prevented from being contaminated by asphalt; the rising hot gas of the asphalt can heat the pump and the asphalt tube, so that self heating is achieved, and extra energy sources are not wasted.

Description

technical field [0001] The invention relates to an asphalt pavement maintenance vehicle, in particular to a pump valve system of an asphalt tank of the asphalt pavement maintenance vehicle, and belongs to the technical field of pavement maintenance devices. Background technique [0002] The maintenance of the existing asphalt pavement and cement concrete pavement is an important part of road construction. Due to the wear and impact of the wheels, the erosion and weathering of natural forces such as heavy rain, flood, sandstorm, ice and snow, sun exposure, ice melting or man-made damage will Many diseases such as potholes, mud pumping, cracks, wrapping, network cracks, and subgrade subsidence have occurred. Regular maintenance of the road surface is required, and asphalt and aggregates are added to the defects. [0003] During road maintenance, the asphalt in the tank is pumped out with a pump. In order to avoid asphalt pollution, the pump and pipeline are installed outside t...
