Description

Technical Field

[0001] The utility model relates to the technical field of mold casting, and more specifically, to a molding sand iron removal device for mold casting. Background Art

[0002] After the casting is poured, the molding sand will undergo great changes in composition and performance due to the strong thermal effect of the metal. The organic matter in the molding sand will sinter into porous fine coke powder and ash. Some of these substances are contained in the sand, and most of them are wrapped on the surface of the sand particles under high temperature to form a layer of strong resin shell and carbon film, and the sand particles will form a larger sand head. The used molding sand cannot be simply reused, otherwise the performance of the molding sand will deteriorate, the quality of the casting will not meet the requirements, and even normal sand making operations cannot be carried out; if the molding sand cannot be regenerated and is discarded after only one use, it will not only pollute the environment, but also waste resources. Therefore, the recycling of molding sand has become increasingly necessary.

[0003] Molding sand usually contains metals such as iron. Before the molding sand is regenerated, the metallic iron needs to be filtered out to prevent the iron from damaging the molding sand and affecting the quality of the molding process. Common sand removal methods include ultrasonic iron removal, magnetic separation and flotation iron removal. Although these methods can effectively remove iron from the molding sand, they are only limited to iron that has already fallen off or is easy to fall off from the molding sand. For molding sand with tightly adhered iron and not easy to fall off, the removal efficiency is low and the removal effect is poor. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a molding sand iron removal device for mold casting, which has the advantage of being able to effectively separate molding sand to which iron substances are tightly adhered and not easy to fall off.

[0005] To achieve the above object, the utility model provides the following technical solution: a sand iron removal device for mold casting, comprising an iron removal body, a mating component installed on one side of the iron removal body, and a material receiving component detachably installed on the bottom of the iron removal body;

[0006] The iron removal body includes an iron removal box, a crushing roller is rotatably connected to the inside of the iron removal box, a placement cavity is provided on one side of the iron removal box, a receiving cavity is provided at the bottom of the iron removal box, a guide chute is provided on one of the opposite inner walls of the receiving cavity, and a limited position recess is provided inside the guide chute;

[0007] The mating component includes a supporting plate, which is fixedly installed inside the placement cavity. An adjusting bolt passes through the inside of the supporting plate. An I-shaped rotating shaft is fixedly installed on one end of the adjusting bolt. The outer side of the I-shaped rotating shaft is rotatably connected to a U-shaped frame, and an arc-shaped mating plate is fixedly installed on the U-shaped frame.

[0008] As an optimal technical solution of the present invention, the crushing roller is driven by a driving motor, a motor support is fixedly installed on the front side of the iron removal box, the driving motor is fixedly installed on the motor support, and a material guide plate is fixedly installed inside the iron removal box and above the crushing roller, and the bottom of the material guide plate is in contact with the outer surface of the crushing roller.

[0009] As a preferred technical solution of the present invention, four movable rollers distributed in a rectangular shape are fixedly installed on the bottom of the iron removal box.

[0010] As a preferred technical solution of the present invention, the arc-shaped matching plate is located inside the placement cavity, and the arc-shaped matching plate is slidably matched with the placement cavity.

[0011] As a preferred technical solution of the present invention, the material receiving assembly includes a material receiving box corresponding to the accommodating cavity. The material receiving box is located inside the accommodating cavity, and the material receiving box is used in conjunction with the accommodating cavity.

[0012] As an optimal technical solution of the present invention, a guide slide adapted to the guide groove is fixedly installed on both side surfaces of the receiving box, the guide slide is slidably connected to the inside of the guide groove, and a rubber protrusion engaged with the limiting recess is fixedly installed on the guide slide.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model pours the molding sand into the interior of the iron removal box as a whole, and the molding sand will fall along the guide plate between the crushing roller and the arc-shaped matching plate. Since the driving motor can drive the crushing roller to rotate, the molding sand between the crushing roller and the arc-shaped matching plate is separated, and the molding sand with iron substances adhering more tightly and not easy to fall off is separated. The molding sand after separation will fall into the interior of the receiving box and be collected by the receiving box. Finally, the molding sand inside the receiving box is poured into the magnetic separator, and the magnetic separator can effectively separate the iron substances from the molding sand. The pretreatment device effectively completes the separation of the iron substances and the molding sand before the magnetic separator is used for processing. After cooperating with the magnetic separator, the removal efficiency of the iron substances is effectively improved, and the technical problems of low iron removal efficiency and poor iron removal effect of molding sand in the prior art are effectively solved.

[0015] 2. The utility model can adjust the distance between the arc-shaped matching plate and the crushing roller, so that the scope of application of the utility model is wider and it is easy to be introduced to the market. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the molding sand will fall along the guide plate 105 to between the crushing roller 102 and the arc-shaped matching plate 205. Since the driving motor 103 can drive the crushing roller 102 to rotate, the molding sand between the crushing roller 102 and the arc-shaped matching plate 205 is separated, so that the molding sand with iron substances adhering more tightly and not easy to fall off is separated. The separated molding sand will fall into the interior of the receiving box 301 and be collected by the receiving box 301. Finally, The molding sand inside the receiving box 301 is poured into the magnetic separator, which can effectively separate the iron material and the molding sand.
