Background technology
Be used for preparing a kind of Modeling Material of molding sand and core sand in Foundry Production.When with clay as moulding sand binder, often produce 1 ton of castings, approximately need supplementary 1 ton of fresh sand, therefore in sand casting is produced, the consumption of casting model powder is maximum.The shape of casting model powder generally divides 3 kinds.1. circular sand: particle is spherical or close to spherical, any surface finish, does not have outstanding corner angle.2. angular sand: particle becomes polygonal, and mostly be obtuse angle.3. pointed shape sand: particle becomes pointed shape, and acute angle is more.
Existing casting model powder needs first could apply after a series of process with casting technique, the means of transportation that present casting model powder adopts is all the mode of belt-conveying, the shortcoming of this means of transportation is: belt utilize itself and casting model powder pile between the frictional force that produces drive casting model powder to move, the travelling speed of belt is determined by electric machine rotation, the travelling speed improving belt must change high-speed electric expreess locomotive, but because high-speed electric expreess locomotive is expensive, the equipment cost of producer can be increased like this; Easily there is the situation of airborne dust in casting model powder, cause plant area to pollute in transportation.
Utility model content
The utility model is intended to provide the casting model powder conveyer that a kind of travelling speed is higher, cost is cheaper.
Casting model powder conveyer in this programme, comprises conveying pot, and the top of this conveying pot has material inlet, and the bottom of conveying pot is connected with discharge nozzle; The tank body of conveying pot has air inlet, and this air inlet place is provided with air filter, and air filter is connected by tracheae with the air compressor outside conveying pot; Be provided with level-sensing device, lower level-sensing device successively in the tank body upper and lower of conveying pot, the bottom of conveying pot is also provided with blast pipe, and this blast pipe is provided with air bleeding valve.
Beneficial effect: by arranging air inlet on the tank body of conveying pot, compressed air is pressed in conveying pot by the air compressor be connected with air inlet, casting model powder is mixed with compressed air, compressed air sweeps along casting model powder to pour in discharge nozzle, is transported at a high speed by casting model powder, compares traditional belt-conveying, the utility model adopts compressed air as transport agent, utilize the swiftly flowing feature of compressed air, transport casting model powder, travelling speed is higher; And all transportations all complete in the tank body closed and pipeline, dust raising phenomenon can not occur, protection worker respiratory safety, avoids plant area and air pollution occurs.
Further, described conveying pot top is provided with extra quality pipe, the V angle place of this extra quality pipe has the sand-falling port communicated with material inlet, the inside, V angle place of extra quality pipe is provided with vertical dividing plate, this dividing plate can move up and down at V angle place, extra quality pipe is divided into two independently chambers by dividing plate, make material from both direction charging, charging rate is faster.
Further, the upper end of described dividing plate is connected with the piston rod of the gate cylinder of extra quality pipe outside, and it is leg-of-mutton valve body that dividing plate lower end is welded with cross section, and the corresponding position of sand-falling port can be blocked in two inclined-planes of valve body.
Further, described blast pipe is provided with muffler, meeting nidus noise during discharge Compressed Gas, noise volume can reduce, in case cause noise pollution by muffler.
Further, discharge nozzle transverse horizontal is stretched out outside conveying pot, and discharge nozzle is fixedly connected with by flange with the conveyance conduit outside conveying pot, connects more firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment casting model powder conveyer.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: gate cylinder 1; Gate 2; Air filter 3; Air bleeding valve 4; Blast pipe 5; Muffler 6; Conveying pot 7; Discharge nozzle 8; Lower level-sensing device 9; Upper level-sensing device 10; Extra quality pipe 11; Air compressor 12.
Embodiment is substantially as shown in Figure 1: casting model powder conveyer, comprises conveying pot 7, and this conveying pot 7 comprises the tank body of cone tubular, and this tank body top is domed end socket.This end socket top has material inlet, and end socket has air inlet on the right side of material inlet, and the left side of end socket material outlet is provided with level-sensing device 10, the detecting head of upper level-sensing device 10 is positioned at conveying pot 7, and this detecting head is fixed with pressure sensing chip, the top of end socket is bolted the extra quality pipe 11 of V-arrangement, the V angle place of this extra quality pipe 11 has the sand-falling port communicated with material inlet, the V angle place sliding fit inside of extra quality pipe 11 has vertical dividing plate, extra quality pipe 11 is divided into two independently feed cavity along V angle center line by this dividing plate, dividing plate upper end is connected by shaft coupling with gate 2 cylinder 1 piston rod of extra quality pipe 11 outside, it is leg-of-mutton valve body that the lower end of dividing plate is welded with cross section, when two inclined-planes of valve body and sand-falling port are close to, can prevent the material in extra quality pipe 11 from falling, when two of valve body have gap between inclined-plane and sand-falling port, material in extra quality pipe 11 just falls into in conveying pot 7 along valve body two inclined-planes.
The air inlet place of end socket is provided with air filter 3, and this air filter 3 is connected with tracheae, and this tracheae is connected with the air compressor 12 outside conveying pot 7.The cone bottom of conveying pot 7 is provided with lower level-sensing device 9; The detecting head of lower level-sensing device 9 is positioned at conveying pot 7, and this detecting head is fixed with pressure sensing chip.The middle part of this cone is connected with blast pipe 5, and this blast pipe 5 is connected with the muffler 6 outside conveying pot 7, air bleeding valve 4 successively.The bottom of conveying pot 7 is connected with discharge nozzle 8, and this discharge nozzle 8 transverse horizontal is stretched out outside conveying pot 7, and discharge nozzle 8 is fixedly connected with by flange with the conveyance conduit outside conveying pot 7.Upper level-sensing device 10, gate 2 cylinder 1, lower level-sensing device 9, air compressor 12, air bleeding valve 4 are all electrically connected with central processing unit.
