Description
Technical field
The utility model relates to the screening plant in a kind of evaporative pattern field, is specifically related to a kind of lost pattern sand-lime dust separating device.
Background technology
Molding sand is production material necessary in lost foam forming process, in order to cost-saving, molding sand normally needs to recycle, molding sand in use easily mixes dust, dust in molding sand directly can affect the quality of foundry goods, so molding sand needs the dust in molding sand to remove before use.Have the dust separating equipment of some molding sand in prior art, the filter screen wherein used is plane, molding sand can be caused like this to be detained at screen cloth two ends, affect filter effect, and after being separated, molding sand is easily left in separator casing.
Utility model content
The utility model is intended to provide a kind of filter effect better, casing easily clear up lost pattern sand-lime dust separating device.
Lost pattern sand-lime dust separating device in this programme, comprises main box, and main box crown center position is provided with feeding mouth, and bottom main box, centre position is provided with discharging opening, connects collecting box below feeding mouth by tube connector, and feeding mouth is relative with discharging opening position; In main box, centre position is provided with screen cloth, and the cross section of described screen cloth is V-arrangement; Both sides, main box top above described screen cloth are all connected with negative tube, and the both sides, main box bottom below described screen cloth are equipped with window.
The utility model has the advantages that: need the feeding mouth of molding sand to be processed above casing to pour into, in molding sand dropping process, part dust can be separated with molding sand, negative tube connects negative pressure device and produces negative pressure, by the dust sucking-off in main box air, molding sand contact screen cloth, thickness molding sand is separated by screen cloth, also the dust in molding sand can be upspring simultaneously, cross section due to screen cloth is V-arrangement, and molding sand can be constantly mobile in the middle of screen cloth, makes the both sides of screen cloth not easily be detained molding sand; The bottom of having filtered rear box is certain to legacy part molding sand, and workman can open the window of main box both sides, uses cleaning device to advance feeding mouth to enter collecting box in the molding sand left over by window.
Further, described window is strip window.Increase working region.
Further, described screen cloth is supported by bracing frame, and support frame as described above two ends are fixed on the inwall of main box.Structure is simple, supporting & stablizing.
Further, be the lower inclined plane of edge to middle discharging opening at the bottom of the case of described main box.Molding sand is not easily trapped at the bottom of case.
Further, described feeding mouth reduces gradually from top to low side diameter.Make charging more smooth.
Further, described tube connector is reduced to collecting box end diameter gradually by feeding mouth end.Pan feeding is more smooth.
Further, described negative tube has 6, and the every side of main box has 3.Make the absorption property of negative tube better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lost pattern sand-lime dust separating device embodiment;
Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
According to Fig. 1,2, the lost pattern sand-lime dust separating device in this programme, comprises main box 1, feeding mouth 2, discharging opening 3, collecting box 4, screen cloth 5, negative tube 6, window 7, bracing frame 8, tube connector 9.
Concrete, the bottom of main box 1 is that feeding mouth 2 is opened in the centre position at main box 1 top by the inclined sliding face of two ends to centre, and feeding mouth 2 is bottom to top enlarging shape, and namely feeding mouth 2 reduces gradually from top to low side diameter.The position of discharging opening 3 and feeding mouth 2 is at same vertical position, and namely discharging opening 3 is opened in centre position bottom main box 1.Be collecting box 4 below discharging opening 3, discharging opening 3 and collecting box 4 are by enlarging shape tube connector 9 UNICOM, and communicating pipe is reduced to collecting box 4 end diameter gradually by feeding mouth 2 end.
Bracing frame 8 comprises crossbeam and is welded on the many root posts on crossbeam, crossbeam two ends are across main box 1 and by screw at main box 1 inwall, many root posts length is different, divides ladder to distribute from low to high in the middle of column to two ends, and the screen cloth 5 of V-arrangement to be just in time placed on bracing frame 8 and to be screwed.Main box 1 both sides above screen cloth 5 are respectively connected with 3 negative tubes, 6,6 negative tubes 6 and are located at same level height and position, and during use, negative tube 6 needs to connect depression generator, and the main box below screen cloth 51 two also has the window 7 of strip.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
