Description

Technical Field

[0001] The utility model relates to asphalt production equipment, in particular to a defoaming and filtering device for asphalt production. Background Art

[0002] Asphalt 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 is used in industries such as coatings, plastics, rubber, and road paving. With the development of asphalt production technology, asphalt is mainly used in the form of hot asphalt, diluted asphalt, and emulsified asphalt. During the asphalt production process, the dilution of emulsifiers and modifiers and their miscibility with asphalt will produce a large amount of foam in the tank. In order to avoid excessive foam overflowing from the top of the tank, causing waste of raw materials and environmental pollution, the asphalt needs to be defoamed and filtered through corresponding equipment.

[0003] In the prior art, some devices have a relatively simple structure, and are prone to stirring and shearing dead corners during operation, which makes it difficult to completely remove bubbles in the asphalt and may require rework, resulting in low work efficiency and poor defoaming quality, leading to waste of asphalt raw materials and increased production costs. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a defoaming and filtering device for asphalt production.

[0005] According to the technical solution provided in the embodiment of the present application, a defoaming and filtering equipment for asphalt production is provided, wherein a removable cover plate is installed on the top of the box body, supporting bottom columns are installed at the corners of the bottom end of the box body, a material trough is dug at the bottom end of the box body, a rotating shaft is placed vertically in the middle part of the box body, a group of material transfer inclined plates are installed on the left and right inner sides of the box body and close to the bottom end, a feed pipe is inserted through the left side of the cover plate, a reagent pipe is inserted through the right side of the cover plate, a groove is dug in the middle part of the cover plate and a bearing is embedded, a speed regulating motor is installed on the upper middle end of the cover plate, a servo motor is installed at the bottom right outer side of the box body, guide plates are staggered on both sides of the feed pipe, the upper end of the rotating shaft extends in the opposite direction and inserts the bearing and is connected to the speed regulating motor through electric rotation, a plurality of groups of equidistantly distributed mixing blades are installed on the left and right sides of the middle part of the rotating shaft, an inverted U-shaped bracket is mounted on the upper end of the rotating shaft, a plurality of evenly distributed first defoaming nets are embedded on each mixing blade, scrapers are installed on both outer sides of the inverted U-shaped bracket, and a plurality of evenly distributed second defoaming nets are embedded on the inverted U-shaped bracket.

[0006] Furthermore, the material transfer inclined plates are placed opposite to each other on the left and right, and a conduit is commonly arranged in the middle between adjacent plates. A valve is arranged on the conduit, and the bottom end is connected to the material trough.

[0007] Furthermore, a propeller rod is suspended horizontally in the trough, and a discharge port is opened on the left side of the trough.

[0008] Furthermore, a control valve is installed on the discharge port, and the bearing and the rotating shaft are adapted to be rotatably connected.

[0009] In summary, the beneficial effects of this application are:

[0010] 1. By setting a mixing fan blade and a defoaming net, a plurality of evenly distributed first defoaming nets and a second defoaming net are respectively embedded on the mixing fan blade and the inverted U-shaped bracket, and the first defoaming net and the second defoaming net are both stainless steel metal nets with the same specifications. The speed regulating motor drives the rotating shaft to rotate, and the mixing fan blade mixes the asphalt, and the bubbles in the asphalt can be stirred and separated, and then the first defoaming net and the second defoaming net are used to achieve defoaming and filtering of the bubbles in the asphalt in the box. The scope is comprehensive, the defoaming and filtering effect is good, the work efficiency is improved, the asphalt production quality is further improved, the loss of raw materials is effectively avoided, and the production cost is reduced; a groove is dug in the middle of the cover plate and a bearing is embedded, and the upper end of the rotating shaft is reversely extended and interspersed with the bearing, which is conducive to the auxiliary rotating shaft driving the mixing fan blade and the inverted U-shaped bracket to rotate smoothly in the box; a scraper is installed on the outside of the inverted U-shaped bracket, and when the asphalt is mixed and defoamed in the box, the asphalt attached to the inner wall of the box can be scraped, further avoiding the loss of raw materials and improving practical performance.

[0011] Second, by setting up a feed pipe and a material trough, guide plates are inserted alternately on both sides of the feed pipe. When the asphalt is input into the box through the feed pipe, the asphalt is guided by the guide plates, which can buffer the impact caused by the gravity of the feed asphalt itself and reduce the foam generated when the asphalt is fed. After the asphalt is mixed and defoamed, the valve is opened and the asphalt is output to the material trough through the material transfer ramp and the conduit. The servo motor is started, and the propeller rod rotates forward or reversely to output the asphalt to the discharge port to avoid the accumulation of asphalt in the trough and the generation of bubbles again.
