Description
Technical field
The invention belongs to tailings recovery technology fields, and in particular to a kind of tailings collects transporter and core shooter tailings returns
Receiving method.
Background technology
At present, China is castings production country maximum in the world, and China's casting total output has just reached 3960 within 2010
Ten thousand tons, the output value is more than 400,000,000,000, and wherein more than 80% using sand casting, and sand casting still accounts in the production of casting
Leading position.With being surging forward for modernization industry, more and more Foundry Works replace making by hand using core shooter and core box
Core.It, can be next time if the tailings remained in core shooter cannot exclude in time but since resin sand itself easily cures
The performance of core shooter is seriously affected during production；Therefore, after core shooting action is completed, it is necessary to which the tailings in core shooter is clear
It removes.Meanwhile for the normal use for ensureing regenerating used system, resin sand is avoided to be bonded in regenerating used system, therefore is needed
Wait tailings that the recycling for losing and just sending into regenerating used system after viscosity and carrying out old sand is fully cured.
Since workshop coremaking region and knockout recovery zone are often apart from each other, the collection transportational process of tailings generally requires
Worker collects antiquated sand using small handcart, and is manually transported to specified region, to complete the regeneration cycle process of tailings.It is existing to penetrate
Core tail sand recovery method is the regeneration for being collected into old sand of core shooter tailings, this process specifically includes：It is collected using cart
--- worker's mobile handcart to knockout region --- treats that tailings cures --- manually tapping cured big sand lump --- and receives to tailings
Small sand lump is delivered in regenerating used system by broken small sand lump --- small sand lump is carried to vibrations band --- the vibrations band of collection
Complete the regeneration of old sand.
In order to ensure being smoothed out for the above process, first, factory has to specially worker to be arranged to be collected tailings,
Transport and hammer action, the labor intensity of worker are big；Secondly as small handcart useful load is limited, collects tailings and generally require
Several workers are generally required when transporting 2-3 times back and forth, and tapping sand lump and coordinate completion, the labor intensity of worker further increases；
Further, since Manual operation link is more during transporting, easily so that tailings drops from cart, so as to cause Foundry Works's work
Make the deterioration of environment；Furthermore when the tailings that need to be handled is more, the storage of trolley will occupy the substantial amounts of area of factory.
With being surging forward for modernization foundary industry, productive temp is also significantly promoted, and production efficiency, manpower are consumed
Take, the requirement of labor intensity it is higher and higher, above-mentioned traditional antiquated sand collects transporter and method does not adapt to make at present
Make the development of industry.
The content of the invention
The present invention provides a kind of tailings to collect transporter, it is intended to which solving cannot be direct after the tailings that cart transports cures
For carrying out the problem of sand regeneration treatment in regenerating used system.
The technical solution adopted by the present invention to solve the technical problems is：Tailings collects transporter, is collected including tailings
