Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel recycling and anti-overflow briquetting devices, in particular to a scrap steel recycling and anti-overflow briquetting device. Background Art

[0002] Scrap steel is currently widely used in smelting. During the scrap steel recycling process, steel mills compress and bale the scrap steel into briquettes, which are then added to the steelmaking process. A scrap steel baler is a device used to recycle and briquette scrap steel.

[0003] When the main ram of the main hydraulic system of existing scrap balers wears out, it can easily carry thin scrap metal debris with it and overflow from the trough during the return stroke. Once this debris is carried out of the hydraulic cylinder support, it cannot be cleaned, causing the main hydraulic cylinder to return abnormally. This accumulation of thin scrap metal further aggravates wear on the hydraulic ram, and the worn main ram requires complete replacement, increasing production costs. Utility Model Content

[0004] Based on this, it is necessary to provide a scrap steel recycling and anti-overflow briquetting device to address the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a scrap steel recycling and processing anti-overflow briquetting device, including a frame and a protective shell, the top of the frame is provided with a box cover, and linear actuators are installed on both sides of the frame, and pressure plates are slidably clamped on both sides of the frame, the output end of the linear actuator is connected to the pressure plate, and a pressure cylinder is installed in the pressure plate, and a plurality of push rods 1 and a pressure block are slidably and sealedly connected in the pressure cylinder, a linear actuator 2 is installed on the frame, the output end of the linear actuator 2 is connected to the pressure block, a movable plate is installed on the pressure block, and a plurality of push rods 2 are installed on the movable plate, and through holes for push rods 1 and 2 to pass through are provided on the pressure plate and the protective shell is provided with an elastic buckle, and a through groove corresponding to the elastic buckle is provided on the outside of the pressure plate, an inclined block is installed on the pressure plate, an extrusion rod is slidably clamped on the inclined block, and the extrusion rod is slidably and sealedly connected to the pressure cylinder.

[0006] Preferably, the movable plate is connected to the pressure block via a plurality of L-shaped connecting plates.

[0007] Preferably, the number of the linear actuators 2 is two, and the two linear actuators 2 are distributed on both sides of the linear actuator.

[0008] Preferably, the inclined block is provided with an inclined groove, and the bottom of the extrusion rod is slidably engaged in the inclined groove.

[0009] Preferably, the spacing between adjacent push rods is not less than 3 cm.

[0010] Preferably, the distance between adjacent push rods is not less than 3 cm.

[0011] Compared with the existing technology, this technical solution has at least one of the following beneficial effects:

[0012] The pressure block slides in the pressure cylinder, and the increased pressure in the pressure cylinder can push the push rods 1 out of the through holes on the pressure plate, so that the iron scrap adhering to the outer shell of the pressure plate can be pushed away from the surface of the pressure plate. When the pressure plate moves, it drives the push rods 2 on the moving plate to push, so that the iron scrap can also be pushed away from the front of the pressure plate.

[0013] The extrusion rod is driven to move by the inclined block, thereby pushing open the elastic buckle on the protective shell and separating it from the pressure plate, thereby facilitating the replacement of the protective shell. BRIEF DESCRIPTION OF THE DRAWINGS

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figures 1 to 4, the embodiment of the present application provides a scrap steel recycling and anti-overflow briquetting device, including a frame 1 and a protective shell 11, a box cover 2 is provided on the top of the frame 1, and linear actuators 3 are installed on both sides of the frame 1. The linear actuator 3 can be a hydraulic cylinder, and its input end is connected to the hydraulic source. Pressure plates 4 are slidably connected on both sides of the frame 1, and the output end of the linear actuator 3 is connected to the pressure plate 4. The pressure plate 4 and the protective shell 11 are both square structures with a groove on one side, so the pressure cylinder 5 can be installed therein, and a pressure cylinder 5 is installed in the pressure plate 4. The internal pressure source of the pressure cylinder 5 can be a hydraulic source or an air pressure source. Several push rods 6 and pressure blocks 7 are slidably and sealedly connected in the pressure cylinder 5. A linear actuator 2 8 is installed on the frame 1, and the linear actuator 2 8 can be non-self-locking. Electric cylinder, so that its output end can move with the pressure plate 7, the output end of the linear actuator 2 8 is connected to the pressure block 7, the pressure block 7 is installed with a movable plate 9, and the movable plate 9 is installed with several push rods 2 10. The pressure plate 4 and the protective shell 11 are provided with through holes 12 for push rods 1 6 and 2 10 to pass through. The diameters of push rods 1 6, 2 10 and through holes 12 are all small, and can push away the sticking iron sheet. The preferred diameter is 1 cm. An elastic buckle 13 is provided in the protective shell 11. The elastic buckle 13 is a triangular buckle in the prior art. The pressure plate 4 is provided with a through groove 14 corresponding to the elastic buckle 13. An inclined block 15 is installed on the pressure plate 4. An extrusion rod 16 is slidably clamped on the inclined block 15. The extrusion rod 16 is slidably and sealedly connected to the pressure cylinder 5.

[0021] In this embodiment, scrap steel enters through the box cover 2 on the top of the frame 1. After the feeding is completed, the box cover 2 is fixed by an external machine, and then the linear actuator 3 drives the pressure plate 4 to move to press the scrap steel. In order to reduce adhesion and facilitate replacement after wear, the pressure plate 4 can be pulled out from the side by the linear actuator 3, and the protective shell 11 can be put on it and pushed back. When the protective shell 11 is installed on the pressure plate 4, the elastic buckles 13 around the protective shell 11 are stuck in the through grooves 14 on the pressure plate 4, so that the scrap steel is squeezed by the surface of the protective shell 11. When the scrap steel adheres, When on the protective shell 11, the linear actuator 3 can drive the pressure plate 4 and the protective shell 11 to retreat, and the linear actuator 2 8 can push the pressure block 7, so that according to the increase in pressure inside the pressure cylinder 5, several push rods 1 6 can slide out from the through hole 12, pushing away the adhered scrap steel, so that the scrap steel can be separated from the surface of the protective shell 11 through the smaller contact area between the push rod 1 6 and the adhered scrap steel. Similarly, when the pressure block 7 is pushed, several push rods 2 10 on the movable plate 9 are also driven to slide out from the through hole 12, pushing away the scrap steel on the front of the protective shell 11. When the protective shell 11 needs to be replaced, the pressure plate 4 can be taken out from the side of the frame 1, and the linear actuator 2 8 can drive the pressure plate 7 to be pulled outward, so that the extrusion rod 16 is pushed out by the inclined surface of the inclined block 15, so that the extrusion rod 16 can squeeze the elastic buckle 13 through the through slot 14, so that the protective shell 11 can be removed. There should be a certain distance between the pressure plate 4 and the side of the protective shell 11, and the front of the two, that is, the side that squeezes the scrap steel, should be in abutment and fitting state. When the briquetting device, that is, the protective shell 11, and the inner wall of the frame 1 are severely worn and can adhere to the scrap steel, it means that there is also a certain gap between the protective shell 11 and the inner wall of the frame 1, so that the push rod 6 can be extended a certain distance. The front of the protective shell 11 can be made of the same hard metal material as the pressure plate 4, and the side wall of the protective shell 11 can be made of a hard rubber material with a certain elasticity as the elastic buckle 13 for easy installation.
