Heating type asphalt filter

Abstract

The invention discloses a heating type asphalt filter which solves the problem that the existing asphalt filter generally adopts one-time filtration and is poor in filtering effect. According to the invention, three times of filtering are completed through the first filtering basket, the second filtering basket and the third filtering basket, and the filtering effect is greatly improved; parallelogram structures are formed among a first rod, a second rod, a third rod, a fourth rod, a fifth rod, a sixth rod, the first filtering basket, the second filtering basket and the third filtering basket, a transmission gear A and a transmission gear B are meshed to transmit motion, the two groups of parallelogram structures are driven to move, rod pieces rotate, the second filtering basket and the third filtering basket are unfolded, all filter plates on the filtering baskets are exposed, so that asphalt on the filter plates can be conveniently dissolved and cleaned by a spray head, and the problem that filter holes are blocked after the asphalt is cooled in the prior art is solved. A lifting device drives the filter to move, so that the filter completes filtering in a first shell and completes filtering plate cleaning in a second shell.

Description

technical field [0001] The invention specifically relates to a heating type asphalt filter. Background technique [0002] Asphalt is a widely used waterproof material and anti-corrosion material. It is mainly used in the waterproofing of roofs, ground and underground structures, and the anti-corrosion of wood and steel. Bitumen is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide, carbon tetrachloride. Asphalt can be mainly divided into coal tar pitch, petroleum pitch and natural pitch, among which coal tar pitch is a by-product of coking, petroleum pitch is the residue after crude oil distillation, and natural pitch is stored underground, and some form ore layers or accumulate on the surface of the earth's crust . [0003] Before asphalt is...

Problems solved by technology

[0003] Before asphalt is used every time, it needs to be heated and filtered to remove impurities before it can be used. The existing asphalt filter generally completes the filtration and removal of impurities through the filter screen, but because the filter screen is in a static state for a long time, the asphalt will stick to the filter screen, resulting in The filter hole is clogged, which seriously affects the filtering effect. At the same time, the existing asphalt filter is generally one-time filtering, and the filtering effect is not good.
