Abstract
The invention relates to a spiral winnowing system and winnowing method for machine-made sand. Through the spiral winnowing system and winnowing method for the machine-made sand, the needed purity degree of the machine-made sand can be obtained through winnowing according to the magnitude of wind pressure, and tiny dust in the machine-made sand can also be completely gathered and used. The spiral winnowing system comprises a dust removing device and a linear vibrating screen. A discharge outlet of the linear vibrating screen is located above a feed inlet of a spiral conveyer. The feed inlet of the spiral conveyer is provided with a dust suction hood. An air blower is arranged on the lower portion of the dust suction hood. The upper end of the dust suction hood communicates with a dust suction pipe of the dust removing device through a dust conveying pipe. The spiral winnowing system and winnowing method have the advantages that winnowing of the purity degree of the surface of the machine-made sand is achieved, and the tiny dust generated by the machine-made sand can also be completely gathered and used, so that the comprehensive additional value of the machine-made sand is greatly improved.
Description
Technical field
The present invention relates to a kind of Machine-made Sand spiral aidr bells blast system and wind selection method that micronic dust in Machine-made Sand according to the degree of purity of Machine-made Sand needed for blast size selecting crude drugs with winnower, can either can be trapped again utilization completely, belong to Machine-made Sand spiral aidr bells blast system and manufacture field.
Background technology
The applicant is at first patent application CN103357577A, title " a kind of machine-made sand wind power aidr bells blast system ", including PLC, it is characterized in that: mixing finished product bucket elevator (01) discharging opening is directly to buffer bin (02) import, buffer bin (02) discharging opening is directly to batcher (03) import, batcher (03) outlet connects with Machine-made sand wind power air separator cabin (06) charging aperture, Machine-made sand wind power air separator cabin (06) multistage discharging opening is respectively through conveying pipeline and respective classification storage tank (09) inlet communication, main air blower (010) air outlet connects with the main air port (21) in Machine-made sand wind power air separator cabin (06), the air outlet paying blower fan (04) connects with a pair air port (22) in Machine-made sand wind power air separator cabin (06), dust removal port (6) in Machine-made sand wind power air separator cabin (06) and cleaner unit (05) inlet communication. see Fig. 3.
Summary of the invention
Purpose of design: on the basis of background technology, design and a kind of adopt the Machine-made Sand after helical feed selecting crude drugs with winnower, adopt wind power direct to give a dinner for a visitor from afar and select Machine-made Sand size, make selecting crude drugs with winnower and helical feed be integrated thus both logical, Machine-made Sand spiral aidr bells blast system and the wind selection method of manufacturing cost and energy consumption can be reduced again.
Design: in order to realize above-mentioned purpose of design. 1, adopt wind-force directly the micronic dust in the Machine-made Sand of linear vibrating screen output to be carried out the design that trapping is reclaimed, be one of the technical characteristic of the present invention. So design purpose be in that: due to linear vibrating screen output Machine-made Sand in substantial amounts of micronic dust, the existence of this micronic dust is the instructions for use of influencing mechanism sand both, causes again the loss with high added value cement additire Machine-made Sand micronic dust. The application adopts wind-force directly Machine-made Sand face to be cleared up, it is possible to effectively blowed floating by the micronic dust on Machine-made Sand surface, negative-pressure air-flow that decoupling mechanism sand is exported by dust arrester siphons away, thus reaching the purpose of dustless recovery. 2, Machine-made Sand surface dust clearance size depends on the design of aerator discharge pressure of fan size, be the present invention technical characteristic two. So the purpose of design is in that: depend on that Machine-made Sand grinds the stress surface in process processed and broken state owing to micronic dust is attached to the adhesive force on Machine-made Sand surface, and when Machine-made Sand belongs to broken state attachment micronic dust, the adhesive force of its micronic dust is little; When Machine-made Sand molding rolls, the adhesive force of its micronic dust is strong, when therefore only having the blast of aerator output big, it is only possible to blow Machine-made Sand and makes to produce between Machine-made Sand and Machine-made Sand collision and make Machine-made Sand surface dust depart from the negative-pressure air-flow that is blown up, kicks up and then exported by dust arrester to siphon away recovery by colliding.
Technical scheme 1: a kind of Machine-made Sand spiral aidr bells blast system, including dust arrester and linear vibrating screen, linear vibrating screen discharging opening is positioned on helical feed machine inlet, helical feed machine inlet is provided with dust shield, dust shield bottom is provided with aerator, and dust shield upper end is connected with dust arrester sweep-up pipe by dust delivering tube.
Technical scheme 2: a kind of Machine-made Sand spiral wind choosing method, the Machine-made Sand of linear vibrating screen discharging opening output is when falling into helical feed machine inlet, being arranged in the wind-force with pressure that the blower outlet below linear vibrating screen discharging opening bloats to be kicked up by the micronic dust of Machine-made Sand and the negative-pressure air-flow that exported by dust arrester by dust excluding hood is siphoned away, own wt then falls in the hopper of conveying worm in gravitational effect more than the Machine-made Sand of wind-force with pressure and is transported on Machine-made Sand conveyer belt by screw auger.
The present invention, compared with background technology, had both achieved the selecting crude drugs with winnower of degree of purity to Machine-made Sand surface, the micronic dust that Machine-made Sand produces can be trapped utilization completely again, make the comprehensive added value of Machine-made Sand be greatly improved.
