Abstract
The invention discloses a pneumatic conveying device which comprises a delivery tank, wherein the lower end of the delivery tank is provided with a conveying pipe; the top of the delivery tank is provided with a lifting air valve connected with an air suction device; and the lifting air valve is communicated with the inner cavity of the delivery tank and provided with a butterfly valve connected with a sand hopper. When the pneumatic conveying device is used, the conveying pipe is mounted in a sand bin firstly, the butterfly valve is connected with the sand hopper, and then the air suction device is started; and as the lifting air valve is communicated with the inner cavity of the delivery tank, the air pressure in the delivery tank is reduced, and under the effect of external air pressure, the molding sand can enter the delivery tank through the conveying pipe and then enter the butterfly valve through the delivery tank so as to finish conveying the molding sand from the sand bin into the sand hopper. By using the pneumatic conveying device, automatic conveying of the molding sand from the sand bin to the sand hopper can be realized, thus the labor intensity of workers can be effectively reduced, the conveying efficiency of the molding sand can be improved, and the need for automatic production can be met.
Description
Technical field
The present invention relates to casting field, particularly a kind of Pneumatic conveyer that transports molding sand from husky storehouse to Sha Douzhong.
Background technology
In modern foundry production, in order to improve the efficient of casting, satisfy the requirement of modern production, employed core uses the hot box shoot core machine manufacturing mostly in the casting process, core shooter is widely used in the foundry machinery industry, it is accurate to have size with the core of hot box shoot core machine manufacturing, and therefore advantages such as any surface finish are obtained using very widely at a lot of foundry enterprises.
Adopting the hot box core shooter to carry out in the foundry production, molding sand need be transported to from sand storage in the sand hopper of hot box core shooter top, could from the sand bucket, in the hot box core shooter, add molding sand then, and then finish manufacturing the loam core by the hot box core shooter.At present send sand mainly to adopt artificial mode to carry out from husky storehouse to Sha Douzhong in molding sand, but because the distance from husky storehouse to the sand bucket is longer, the workload of therefore to the sand bucket, carrying molding sand from husky storehouse very greatly, carry molding sand if adopt artificial mode merely, not only working strength of workers is very big, and production efficiency is very low, carries the speed of molding sand often not satisfy the needs of producing, and then production is impacted.
Summary of the invention
At above-mentioned the deficiencies in the prior art, but the technical problem to be solved in the present invention provides a kind of Pneumatic conveyer of automatic transport molding sand.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Pneumatic conveyer, it comprises that one sends jar, the described lower end that sends jar is provided with carrier pipe, the described top that sends jar is provided with a lifting air valve that is connected with getter device, described lifting air valve is communicated with the described inner chamber that sends jar, and described lifting air valve is provided with a butterfly valve that can be connected with the sand bucket.
Preferably, it also comprises a gas pipeline, and an end of described gas pipeline is communicated with the described top that sends jar, and the other end of described gas pipeline is communicated with described carrier pipe.
Preferably, described transmission jar is provided with observation window.
Technique scheme has following beneficial effect: this Pneumatic conveyer in use, at first carrier pipe is installed in Sha Kunei, butterfly valve is connected with husky bucket, start getter device then, be communicated with a transmission jar inner chamber owing to promote air valve, therefore send a jar internal gas pressure and diminish, externally molding sand can enter in the transmission jar by carrier pipe under the effect of atmospheric pressure, enter in the butterfly valve by sending jar again, thereby finish molding sand from the conveying of sand storage in sand hopper.Use this Pneumatic conveyer can realize molding sand, thereby can effectively reduce working strength of workers, improve the transfer efficiency of molding sand, satisfy the needs of automated production from the automation of sand storage to sand hopper conveying molding sand.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this Pneumatic conveyer comprises a transmission jar 1, and the lower end that sends jar 1 is provided with carrier pipe 5, and the top that sends jar 1 is provided with a lifting air valve 2 that is connected with getter device, promote air valve 2 and be communicated with, promote air valve 2 and be provided with a butterfly valve 3 that can be connected with the sand bucket with the inner chamber that sends jar 1.
This Pneumatic conveyer in use, at first carrier pipe 5 is installed in Sha Kunei, butterfly valve 3 is connected with husky bucket, start getter device then, be communicated with a transmission jar inner chamber owing to promote air valve 2, therefore sending jar 1 internal gas pressure will diminish, and externally molding sand can enter in the transmission jar 1 by carrier pipe 5 under the effect of atmospheric pressure, enter in the butterfly valve 3 by sending jar 1 again, thereby finish molding sand from the conveying of sand storage in sand hopper.
Because it is far away apart from the distance of carrier pipe 5 to promote air valve 2, therefore suction not enough problem in carrier pipe place might appear, also be provided with a gas pipeline 4 on this device for this reason, one end of gas pipeline 4 is communicated with the top that sends jar 1, the other end of gas pipeline 4 is communicated with carrier pipe 5, so just can make carrier pipe 5 identical, thereby can effectively increase the suction at carrier pipe 5 places with the pressure that sends jar 1 top.For the ease of observing the situation that sends the sand in the jar 1, also be provided with an observation window 6 on this transmission jar.
Use this Pneumatic conveyer can realize molding sand, thereby can effectively reduce working strength of workers, improve the transfer efficiency of molding sand, satisfy the needs of automated production from the automation of sand storage to sand hopper conveying molding sand.
More than a kind of Pneumatic conveyer that the embodiment of the invention provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
