Fuel filling and filtering system of paving machine

Abstract

The invention discloses a fuel filling and filtering system of a paving machine. The fuel filling and filtering system comprises a container. A cover is arranged on the upper portion of the container, a cylindrical filter element is vertically arranged in the container, an output port in the lower end of the filter element is connected with a fuel tank of the paving machine by a first connecting pipe, a three-way connector is mounted on the fuel tank of the paving machine, a first port of the three-way connector is communicated with the fuel tank of the paving machine, a second port of the three-way connector is communicated with the upper portion of the container via a second connecting pipe, and a third port of the three-way connector is connected with an air breathing apparatus; the air breathing apparatus comprises an air breathing apparatus body, a partition plate is arranged on the inner wall of the air breathing apparatus body, a threaded pipe which is connected with the three-way connector in a threaded manner is connected to the bottom of the partition plate, a plurality of first air holes are formed in the partition plate, and a plurality of second air holes are formed in the partition plate and are positioned on the outer side of the threaded pipe; a drain valve for draining water in the container is connected to the bottom of the container. The fuel filling and filtering system of the paving machine has the advantages that the fuel filling and filtering system is high in fuel filling speed, the water can be drained conveniently, air can be exhausted smoothly, and the quality of fuel which flows into an engine can be guaranteed.

Description

technical field [0001] The invention relates to a filter system, in particular to a paver fuel filling filter system. Background technique [0002] In recent years, the mixture paver has gradually developed in the direction of large width, high productivity, high operation quality and multi-function. One of the key technologies to ensure high operating quality under large width and high productivity is the fuel refueling filter system. [0003] At present, the design of the fuel refueling filter system of various domestic paver is to simply purchase the filter element, and the fuel enters the fuel tank through the filter element, which cannot effectively exhaust and filter. Under the premise of low productivity, this A design scheme can meet its requirements. In order to meet the new demands of the market for various performance indicators of the paver, the previous simple design scheme of the fuel refueling filter system cannot meet the requirements. According to the pri...
