Description
Technical field
The utility model relates to a kind of precoated sand production equipment, especially relates to a kind of dry type precoated sand coating machine.
Background technology
Traditional Making mold adopts common river sand, and the model made is more open, and intensity is low, and the utilization rate of sand is lower, and discarded sand, with a large amount of harmful substances, effectively cannot reclaim, cause pollution to environment.Cover molding sand or the core of one deck hard resin at sand grain surface before precoated sand refers to moulding, because its intensity is high, gas forming amount is low, production casting dimension accuracy advantages of higher, get a lot of applications in mechanical manufacturing field in recent years, existing precoated sand mostly adopts wet method to make, namely sand grains soaks in the solution, this method speed of production is comparatively slow, and product quality is uncontrollable.
Utility model content
The purpose of this utility model is to provide a kind of dry type precoated sand coating machine, and efficiently solve the problem of existing precoated sand production technology production efficiency underground, the technical scheme of employing is as follows:
A kind of dry type precoated sand coating machine, comprise frame, described frame sets firmly a batch mixing bucket, described batch mixing bucket upper end open is greater than lower ending opening, side, described batch mixing bucket upper end is provided with a sand-feeding tube, described sand-feeding tube is connected with air compressor machine by pressurizing chamber, described pressurizing chamber top is provided with feed hopper, described frame is positioned at directly over batch mixing bucket and is provided with a gantry support, emery wheel penetrated by the described gantry support lower end round platform that is coupling, describedly penetrate emery wheel and sand-feeding tube is just right, described emery wheel of penetrating is connected with alternating current generator by speed changer, described batch mixing bucket one sidewall is also provided with a resin playpipe, described resin playpipe connects heating chamber, described heating chamber is connected with supercharger and feed pipe respectively.
Further, described batch mixing bucket lower openings place is provided with axial flow air inlet fan.
Further, described resin playpipe height is lower than the height of sand-feeding tube.
Further, non-return valve is provided with between described heating chamber and feed pipe.
After adopting this structure, dry type production can be carried out to precoated sand, improve the quality of production and the speed of precoated sand.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of dry type precoated sand coating machine.
Detailed description of the invention
A kind of dry type precoated sand coating machine as shown in Figure 1, comprise frame 1, described frame 1 sets firmly a batch mixing bucket 10, described batch mixing bucket 10 upper end open is greater than lower ending opening, batch mixing bucket 10 lower openings place 12 is provided with axial flow air inlet fan 11, side, described batch mixing bucket 10 upper end is provided with a sand-feeding tube 5, described sand-feeding tube 5 is connected with air compressor machine 4 by pressurizing chamber 3, described pressurizing chamber 3 top is provided with feed hopper 2, described frame 1 is positioned at directly over batch mixing bucket 10 and is provided with a gantry support 7, emery wheel 6 penetrated by the described gantry support 7 lower end round platform that is coupling, it is described that to penetrate emery wheel 6 just right with sand-feeding tube 5, described emery wheel 6 of penetrating is connected with alternating current generator 9 by speed changer 8, described batch mixing bucket 10 1 sidewall is also provided with a resin playpipe 131, resin sprays the height of 3 pipe height lower than sand-feeding tube 5, described resin playpipe 13 connects heating chamber 14, described heating chamber 14 is connected with supercharger 15 and feed pipe 16 respectively, non-return valve 17 is provided with between heating chamber 14 and feed pipe 16.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
