Problems solved by technology

[0003] Most of the current molding sand recycling processes are manual operations, which are labor-intensive, generate large amounts of dust, and work in a harsh environment; moreover, the recycling quality of molding sand will be affected by manual operations, especially for the orbs used in precision casting. Sand, the price is relatively expensive, and the recycling quality of molding sand will directly affect the molding quality of castings. Therefore, it is necessary to improve the recycling efficiency and quality of molding sand, and reduce the labor intensity

Embodiment 1

[0023] see Figure 1-4 , a molding sand recycling and screening device, comprising a treatment box 1, the top of the treatment box 1 is fixedly connected to the feed hopper 2, and both ends of the top in the treatment box 1 are fixedly connected to a fixing seat 3, and the fixing seat 3 is provided with an extrusion crushing device, the bottom between the two fixed seats 3 is provided with a feeding port, both sides below the feeding port are provided with crushing wheels 4, one end of the crushing wheel 4 is connected to the processing box 1 in rotation, and the bottom of the crushing wheel 4 There is a screening box 12, the top opening of the screening box 12 is set, the bottom of the screening box 12 is provided with a screening installation port, and the screening installation port is fixedly connected to the screen, and the inner wall of the processing box 1 on both sides of the screening box 12 is fixed. The seat 10 and the side seat 10 are provided with a guiding mechan...

Embodiment 2

[0031] see Figure 1-4 , the other content of this embodiment is the same as that of Embodiment 1, the difference is that: the bottom end of the first moving seat 6 is fixedly connected to the bottom bar 17, the bottom end of the bottom bar 17 is fixedly connected to the bottom plate 18, and the bottom end of the bottom plate 18 It is fixedly provided with dense bristles 19 .

[0032] In the implementation process of the present invention, first pour large pieces of molding sand waste from the feed hopper 2 into the treatment box 1, and then start the drive motor to drive the crushing wheel 4 to move, and the crushing wheel 4 drives the first moving seat 6 to reciprocate when moving , so that the extrusion block 7 moves to squeeze the molding sand waste, and at the same time, it can also drive the screening box 12 to move in a horizontal and vertical direction to screen the molding sand particles.

[0033] In the present invention, large pieces of molding sand can be squeezed...

Abstract

The invention discloses a molding sand recycling and screening device, and relates to the technical field of molding sand recycling treatment. The molding sand recycling and screening device comprisesa treatment box, an extrusion crushing device is arranged in a fixing base, crushing wheels are arranged on the two sides below a material falling opening, one ends of the crushing wheels are rotationally connected with the treatment box, a screening box is arranged below the crushing wheels, an opening is formed in the top of the screening box, a screening installing opening is formed in the bottom of the screening box, a screen is fixedly connected into the screening installing opening, side bases are fixedly connected to the positions, on the two sides of the screening box, of the inner wall of the treatment box correspondingly, guide mechanisms are arranged in the side bases, and connecting blocks are fixedly connected between the guide mechanisms and the screening box. According to the molding sand recycling and screening device, massive molding sand fragments can be extruded and crushed by arranging the extrusion crushing device, the molding sand fragments can be further crushedby arranging crushing wheels, crushed molding sand particles can be screened by arranging the screening box, the screening box can move in a reciprocating mode by arranging the guide mechanisms so that the screening efficiency can be effectively improved, and the screening effect is improved.

Description

technical field [0001] The invention relates to the technical field of molding sand recycling and processing, in particular to a molding sand recycling and screening device. Background technique [0002] In the field of mechanical casting, molding sand is often used for molding and casting. In order to reduce production costs, molding sand needs to be reused. However, after casting, the molding sand contains various impurities, so it needs to be recycled by machinery. During the casting process, the molding sand will inevitably form lumps, and there will be a lot of steel slag in the molding sand near the cavity. When recycling the molding sand, it is necessary to break the molding sand and then screen it to remove impurities. Recycling. [0003] Most of the current molding sand recycling processes are manual operations, which are labor-intensive, generate large amounts of dust, and work in a harsh environment; moreover, the recycling quality of molding sand will be affecte...
