Abstract
The utility model relates to a foundry waste sand dealkalize regeneration treatment device, including taking out sandpipe, horizontal screw conveyer, hopper, perpendicular screw conveyer, support I, support II and adding the acid tube, horizontal screw conveyer fixes in the upper end of support II, and perpendicular screw conveyer fixes in the upper end of support I, and is the setting of 30 -175 contained angle between horizontal screw conveyer and the perpendicular screw conveyer, horizontal screw conveyer's feed end with take out the sandpipe and be connected, horizontal screw conveyer's the discharge end and the access connection of hopper, the export and the perpendicular screw conveyer of hopper are connected, the lateral wall of hopper is provided with the acidification hole, the discharge end that adds the acid tube is connected to the acidification hole of hopper. The utility model has the advantages of simple structure, low in manufacturing cost adds hydrochloric acid through adding the acid tube in to foundry waste sand, improves the na2O clearance greatly, makes the product rate of recovery improve, and the return sand can be used to building material, resources are saved and environmental protection.
Description
Technical field
The utility model relates to recycling cast waste sand reuse field, particularly a kind of cast waste sand dealkalize regenerating treater.
Background technology
Casting industry is the basic activity in manufacturing industry, and the development of all trades and professions all be unable to do without foundry goods.But China's castings production per ton will discharge waste sand about 1 ton, year discharge cast waste sand more than 3,000 ten thousand tons, cast waste sand is alkalescence, not even a blade of grass grows to topple over part, resource consumption and environmental pollution are all very surprising, and therefore the process of cast waste sand and recycling have become current problem in the urgent need to address.But recycling cast waste sand device bulky complex in prior art, cost is high, and Na after cast waste sand dealkalize
2the residual quantity of O is still higher, and product recovery rate is low.
Utility model content
The purpose of this utility model is to provide a kind of cast waste sand dealkalize regenerating treater, and apparatus structure is simple, low cost of manufacture, Na
2o clearance is high, and product recovery rate is high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cast waste sand dealkalize regenerating treater, comprise and take out sandpipe, horizontal conveying worm, hopper, vertical screw type conveyer, support I, support II and add acid tube, described horizontal conveying worm is fixed on the upper end of support II, vertical screw type conveyer is fixed on the upper end of support I, and arrange in 30-175 ° of angle between horizontal conveying worm and vertical screw type conveyer, the feed end of horizontal conveying worm with take out sandpipe and be connected, the discharge end of horizontal conveying worm is connected with the import of hopper, the outlet of hopper is connected with vertical screw type conveyer, the sidewall of hopper is provided with acid adding hole, the described discharge end adding acid tube is connected to the acid adding hole of hopper.Described support I and support II connect to form by channel-section steel.
Compared with prior art, the utility model has following beneficial effect: a kind of cast waste sand dealkalize of the utility model regenerating treater, the structure of device is simple, and low cost of manufacture, adding hydrochloric acid by adding acid tube, greatly improving Na in cast waste sand
2o clearance, product recovery rate is improved, and return sand can be used for construction material, economizes on resources and protection of the environment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of cast waste sand dealkalize regenerating treater;
Mark in figure: 1, take out sandpipe, 2, horizontal conveying worm, 3, hopper, 4, vertical screw type conveyer, 5, support I, 6, support II, 7, add acid tube.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated; the present embodiment is premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in the figure, a kind of cast waste sand dealkalize regenerating treater, comprise and take out sandpipe 1, horizontal conveying worm 2, hopper 3, vertical screw type conveyer 4, support I 5, support II 6 and add acid tube 7, horizontal conveying worm 2 is fixed on the upper end of support II 6, vertical screw type conveyer 4 is fixed on the upper end of support I 5, support I 5 and support II 6 connect to form by channel-section steel, firmly solid.Take out sandpipe 1 is extracted in horizontal conveying worm 2 by the mixture of cast waste sand and hydrochloric acid from fermentation vat, mixture promotes the import department being transported to hopper 3 through horizontal conveying worm 2, the sidewall of described hopper 3 is provided with acid adding hole, the discharge end adding acid tube 7 is connected with acid adding hole, add acid tube 7 in fermentation vat, extract hydrochloric acid and make hydrochloric acid enter in hopper 3 by acid adding hole, mixture again mixes with hydrochloric acid in hopper 3, hopper 3 outlet is connected with vertical screw type conveyer 4, mixture enters vertical screw type conveyer 4 through hopper 3 outlet, cast waste sand mixes in vertical screw type conveyer 4 with the mixture of hydrochloric acid.Na in cast waste sand
2o and hydrochloric acid generation chemical reaction also remove Na
2o, the return sand of regeneration can be used for construction material, economizes on resources and protection of the environment.Arrange in 30-175 ° between horizontal conveying worm 2 and vertical screw type conveyer 4, make cast waste sand and mixed in hydrochloric acid evenly.
A kind of cast waste sand dealkalize of the utility model regenerating treater, the structure of device is simple, and low cost of manufacture, adding hydrochloric acid by adding acid tube 7, greatly improving Na in cast waste sand
2o clearance, product recovery rate is improved, and return sand can be used for construction material, economizes on resources and protection of the environment.
