Description

SCRAP GRINDING MACHINE

Technological Area:

This invention is about a scrap grinding machine that can be used in grinding high tonnages of scrap metals.

Current Situation of the Technique:

Today waste and scrap products that expired their life are used for recycling or disposed of according to their type. In order to successfully achieve the so said recycling or disposing of process these products must be downsized. To downsize the waste and scrap products, crusher and shredder machines are used.

In the current technique of the machines in use, the waste and scrap products given through a feeding tank are transferred to a section with blades attached on a turning rotor and then crushed. For the feeding tank in these machines are small, the parts can be downsized only after being crushed in an another machine. This brings a necessity to process in separate machines and so causes cost and inefficient process.

One of the other problems in the current technique is that many other materials can also be thrown to the feeding section of the scrap grinding machine along with scrap. Soil and other materials entering together with the scrap stick to the blade surfaces and gaps between the blades so causes the cutting not being able to be performed appropriately. For this reason, the scrap needs to be separated from these foreign materials.

Scrap machines in the current technique contains only the blades that enables shredding and this causes the scrap to be ground nonhomogenously. Applying more than one process (shredding, cutting, grinding etc.) on the scrap inside the machine, enables it to be more utilizable for keeping and using in recycle. In the patent application numbered TR201721790, the "Scrap metal pressing machine" is described. The invention is a scrap metal pressing machine which contains a top pressing lid that presses the main body and a ram that presses inside the body from the sides of the main body in order to press scrap metals within a main body.

In the patent application numbered US5044567A, the "Scrap grinding machine" is described. The purpose of the invention is to offer a scrap crushing machine that has a case constructed in a way to not to need to turn the screen wall anymore to quickly empty the case.

In the inventions mentioned above the scrap is only put to shredding process inside the machine. These machines fall short in grinding high tonnages of materials. There are no additional systems that separates the scrap entering the machine from other materials.

In conclusion, there's a need for a new technology that can overcome the disadvantages mentioned above, has an improved scrap screening system, can make mass grinding, shred high tonnages of load, has conveyor bands which enables the scraps to be transferred, can do not only shredding but also crushing, cutting and grinding processes.

Definition of Invention:

This invention is a new technology that can overcome the disadvantages mentioned above, has an improved scrap screening system, can make mass grinding, shred high tonnages of load, has conveyor bands which enables the scraps to be transferred, can do not only shredding but also crushing, cutting and grinding processes.

Blades in our invention has four different jag forms for four different processes. These blades crush, shred, cut and grind the scraps entering the system. By this means, downsizing the big sized scraps entering system can be made much more efficiently and appropriately. Our system is assembled to grind high tonnages of loads and corresponds to a weight of about 300 tons in total. There's an automatic transmission system and a torque converter which is capable of rotating the flywheel section of a machine of this weight up to 3000 rpm and reduce and raise the rotations of it. The rotation reducing-raising process in this system is enabled by the pneumatic systems in the transmission connected to the air compressor.

The scrap screening system in our invention enables the scraps entering the scrap grinding machine to be separated from other materials such as soil, sand etc. This happens by means of the screen pawls connected to the crank shaft which moves by the engine. While big sized scraps are directly transferred to the conveyor band through the transferring sheet, the small sized metals are separated from the soil by the magnetic field created by the inductive plate.

With the help of the two different cooling systems in our invention, the hot oil circulating through the system can be continuously cooled down. In the air cooling system, the oil passes through the radiator and gives its' heat to the environment and these capillary tubes happen to be cooled by the fan. In the gas cooling system it's the other way, meaning that compressed nitrogen passes through the radiator. Radiators in the gas cooling system are generally located as dipped into the hot oil. Hot oils in here gives heat to the cold nitrogen passing through the radiator and the cooling process of hot oil is finalized.

The engine (1) in the invention is located inside the block body (19). The first oil pump (3) is connected at the engine (1) shaft end. And the lid (2) is located on top of the engine (1). The first hydromotor (4) is connected to the first oil pump (3) outlet shaft. And the first automatic transmission (6) is connected to the first hydromotor (4) outlet shaft. The flywheel (21) is located at the first automatic transmission (6) outlet shaft. The second oil pump (16) is located at the flywheel (21) outlet. The second hydromotor (17) is located at the second oil pump (16) outlet shaft and the second automatic transmission (18) is located at the second hydromotor (17) end. The moving turnplate (20) is connected to the second automatic transmission (18) outlet shaft. There are blades on the moving turnplate (20) and inside the block body (19). The shredding jag

(22.2), the cutting jag (22.3) and the grinding jags (22.4) are placed respectively at the upmost, middle and lowermost parts of the moving tumplate (20). The column (23) is located under the moving tumplate (20) and the material collection plate (24) is located under the column (23). At least one ball (25) is placed at the material collection plate (24) lower shaft. The material inlet (19.1) section is connected with the scrap screen (26) and the material outlet (19.2) is connected with the material collection plate (24).

The operating principle of the system subject to invention is as follows; the engine (1) in the system is powered by the power line. The engine (1) shaft provides motion to the first oil pump (3) and the pump draws oil from the cooled hydraulic tank (8). Then the pressurized oil is sent to the first hydromotor (4). The first hydromotor (4) converts the pressurized oil to mechanical energy and transmits this energy to the first automatic transmission (6). With the compressed air from the compressor the first automatic transmission (6) can perform rotation reducing-raising when desired, the first automatic transmission (6) begins to rotate the 50 tons flywheel (21) connected to the outlet shaft from slow to an average speed until it reaches to 3000 rpm. the second oil pump (16) connected to the flywheel (21) begins to create pressure. The second oil pump (16) sends compressed oil to the second hydromotor (17) and the mechanical energy generated here is transmitted to the second automatic transmission (18). then the moving tumplate (20) and the blades (22) connected to the second automatic transmission begin to rotate. Meanwhile the truck approaching the ascending ramp

(26.1) transfers the scrap pile to the drop site (26.2). The pile is scrabbled by the screen pawls (26.4) and the soil and metal is separated. The soil is transferred to the soil band (26.9) and the metal is transferred to the scrap conveyor band (26.8). Metals that can't be separated from the soil are stuck to the magnetic scrap separating band (26.10) with the inductive plate (26.12). Metal scraps on the scrap conveyor band (26.8) enters by the material inlet (19.1) and fills in the canal gaps in between. The scrap pile is respectively shredded, cut and ground by means of the blades (22). These ground scraps are then dropped on to the material collection plate (24) and sent from here to the material outlet

(19.2).
