Abstract

The utility model discloses a separating screen used for foundry casting production, and belongs to the technical field of separation mechanical devices. The separating screen comprises a support, a screen body and a hopper, the screen body is arranged on the support in an inclined mode, and the hopper is arranged at one end of the high side of the screen body. The screen body comprises a chute and a screen, the screen is hung in the chute, one end of the low side of the screen is provided with an end plate arranged in an inclined mode, a coarse material outlet is formed in the side, provided with the low side of the end plate, of the screen, a material baffle is arranged on the middle section of the screen, and a screen vibration device is further arranged on the screen. The separating screen used for foundry casting production is simple in design, reliable in structure, and capable of effectively separating massive materials or metal pieces from molds through quartz sand and discharging the massive materials or the metal pieces through the coarse material outlet in time, and has the advantage of being high in removing efficiency. The potential hazard problems that the mechanical strength of the casting molds is lowered or even the casing quality is affected due to addition of the massive materials or the metal pieces are effectively solved.

Description

The separating sieve of producing for foundry casting

Technical field

The utility model relates to a kind of automatic sorting sieve, and particularly a kind of automatic sorting sieve of producing for foundry casting, belongs to sorting machine equipment technical field.

Background technology

In foundry casting is produced, the recycling of mould quartz sand need to be made to mould, but in production or transport process, in quartz sand, can sneak into unavoidably larger other block materials or metalwork, if block material or metalwork are sneaked in Mold Making, affect the mechanical strength of mould, if be positioned at the inner surface of mould, also can cause serious quality influence to foundry goods.

Summary of the invention

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, a kind of automatic sorting sieve of producing for foundry casting is provided, can isolate fast block material or metalwork in Mold Making raw material quartz sand, improve the mechanical strength of mould, avoid block material or sneaking into of metalwork and affect casting quality.

The technical solution adopted in the utility model is as follows:

A kind of separating sieve of producing for foundry casting, comprise support, sieve nest and hopper, described sieve nest is obliquely installed on support, hopper is arranged at the end of the high point of sieve nest, and described sieve nest comprises chute and screen cloth, and described screen cloth hangs and is arranged in chute, the end of screen cloth low spot is provided with the end plate of inclination, the sidepiece of end plate low spot place screen cloth offers coarse fodder outlet, and the stage casing of described screen cloth is provided with striker plate, is also provided with screen vibrator on screen cloth.

Further, described screen vibrator is Pneumatic vibration stick.

The inclination angle of described sieve nest is 50-60 °.

The separating sieve of producing for foundry casting of the present utility model, when casting enters after sieve nest by hopper with quartz sand, under the screen vibrator vibrations of sieve nest, make separating of fines and coarse fodder, fines skids off from chute, the end plate that coarse fodder is arranged by the sloped-end of screen cloth downside automatically slips into coarse fodder outlet and discharges, and the design of striker plate makes can carry out in the stage casing of screen cloth certain keeping out and stopping at the raw material that enters screen cloth, extends the time of staying of sub-sieve material at sieve nest; The quartz sand of using due to founding has certain humidity simultaneously, need to guarantee that sieve nest has more precipitous angle of inclination, through evidence, in the time that the inclination angle of sieve nest is 50-60 °, when can meeting fine sand material after screening and automatically fall along chute, effectively avoided only guaranteeing that by extending sieve nest length screening material has the drawback of suitable stop sieving time on sieve nest, the Pneumatic vibration stick adopting has advantages of that volume is little, easy for installation.

In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: the described separating sieve of producing for foundry casting, simplicity of design, reliable in structure, can be effectively by block material or metalwork from mould with separating quartz sand, and export in time and discharge by coarse fodder, have advantages of that separating sieve removal efficiency is high, effectively solve that block material or metalwork are sneaked into and the casting die mechanical strength that causes reduces, even affected the potential risk problem of casting quality.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment

The separating sieve of producing for foundry casting of the present utility model, its structure as shown in Figure 1, comprise support 1, sieve nest and hopper 4, described sieve nest ° is arranged on support 1 take inclination angle as 50-60, 50-60 ° angle is set can guarantees that quartz sand has in certain humidity situation, the fine sand material meeting after screening falls automatically along chute, simultaneously in the time of staying at sub-sieve material, in the length of sieve nest, make optimum balance, guarantee the effect of sub-sieve, described hopper 4 is arranged at the end of the high side of sieve nest, described sieve nest comprises chute 2 and screen cloth 3, described screen cloth 3 is hung and is arranged in chute 2 by the spring 9 arranging, the distance that the wire side of screen cloth 3 and chute 2 bottom surfaces are reserved with 10-15cm can slide (as shown in Figure 3) by chute 2 smoothly with the quartz sand that guarantees screening, the end of screen cloth 2 downsides is provided with the end plate 7 being in tilted layout, the sidepiece of end plate 7 downside place screen clothes 3 offers coarse fodder outlet 5, the end plate 7 being in tilted layout is conducive to point coarse fodder sifting out automatically and exports 5 by coarse fodder timely discharge (as shown in Figure 2).

On the sidewall of screen cloth 3 of the present utility model, be also provided with Pneumatic vibration stick 8 to improve a point screen capacity as screen vibrator, the stage casing of screen cloth 3 is also provided with striker plate 6 simultaneously, striker plate 6 is 45-80 ° of inclination angle with screen cloth 3 wire side place planes, and between striker plate 6 and screen cloth 3 wire sides, remain with the gap of 5-10cm, to guarantee at hopper 4 loads too much in the situation that, striker plate 6 can do certain keeping out and distribute to sub-sieve material, to improve the effect of sub-sieve.

The separating sieve of producing for foundry casting of the present utility model, frame 1 side is also provided with for observing hopper 4 helpers.

The separating sieve of producing for foundry casting of the present utility model, simplicity of design, reliable in structure, can be effectively by block material or metalwork from mould with separating quartz sand, and export in time and discharge by coarse fodder, have advantages of that separating sieve removal efficiency is high, effectively solve that block material or metalwork are sneaked into and the casting die mechanical strength that causes reduces, even affected the potential risk problem of casting quality.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
