Technical Field

The utility model relates to the technical field of concrete processing, in particular to a separation device for concrete aggregates.

Background technique

Concrete aggregates include concrete blocks and dust. When screening them, the concrete blocks and dust need to be screened and separated. Then, after a period of screening, the conventional separation device needs to clean the filter plate regularly, otherwise the problem of concrete block accumulation will easily occur.

Summary of the invention

The technical problem to be solved by the utility model is that the aggregate of concrete includes concrete blocks and dust, etc. When screening the aggregate, the concrete blocks and the dust need to be screened and separated, and then the conventional separation device needs to regularly clean the filter plate after screening for a period of time, otherwise the problem of concrete block accumulation will easily occur.

In order to solve the above problems, the technical solution adopted by the utility model is: a separation device for concrete aggregates, including a screening bin, a feed hopper is installed at the upper end of the screening bin, a screening plate for screening aggregates is provided inside the screening bin, and a discharge port for convenient aggregate discharge is opened on the side wall of the screening bin, and a driving component for controlling vibration screening of aggregates is provided inside the screening bin, and the driving component includes a mounting rod fixedly mounted on the inner wall of the screening bin, the screening plate is sleeved on the surface of the mounting rod and is inclined, and a reset component for resetting the screening plate is also provided between the screening plate and the screening bin.

The beneficial effect of the utility model is as follows: through the provided screening bin and screening plate, when aggregate needs to be screened, material is fed into the screening bin through the feed hopper, the aggregate falls onto the screening plate, and the screening plate is used to screen the aggregate, wherein large particles of aggregate remain on the surface of the screening plate, while fine dust falls to the bottom of the screening bin; since the screening plate is inclined, the large particles of aggregate after screening roll along the screening plate until they are discharged from the discharge port.

As a further improvement of the present invention, the technical problem to be solved is: although the filter screen can achieve a real-time discharge effect, after a period of time, the filter screen is prone to accumulate dust, resulting in the problem of mesh becoming plain.

In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the reset assembly includes a fixed plate fixedly installed on the inner wall of the screening bin, a guide rod is fixedly installed on the bottom of the fixed plate, the bottom of the guide rod slides through the surface of the screening plate, and a spring is also sleeved on the surface of the guide rod.

The beneficial effect of the above improvement is as follows: through the setting of the fixed plate and the guide rod and the spring sleeved on the surface of the guide rod, after a certain amount of large-particle aggregate is gathered on the surface of the screening plate, the screening plate can be rotated from the state of left low and right high to the state of left high and right low, thereby facilitating the large-particle aggregate on the surface of the screening plate to roll down and be discharged from the discharge port; after the large-particle aggregate is discharged, the screening plate is reset under the action of the spring, and the screening plate is vibrated, thereby preventing the problem of blockage of the screening plate mesh.

As a further improvement of the utility model, the technical problem to be solved is: the problem that the screening plate is prone to interfere with the guide rod during the rotation process.

In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: a through groove is further provided on the surface of the screening plate at a position corresponding to the guide rod, and the through groove is in a long strip shape.

The beneficial effect of the above improvement is that, by means of the through grooves provided on the surface of the screen plate, when the screen plate rotates, the problem of jamming and interference between the screen plate and the guide rod can be avoided.

As a further improvement of the utility model, the technical problem to be solved is: the concrete block is easy to roll down to the left side of the screening plate during the screening process.

In order to solve the above technical problems, the utility model further improves and adopts a technical solution as follows: a partition plate is fixedly installed on the upper end surface of the screening plate near the guide rod.

The beneficial effect of the above improvement is that the partition plate provided on the upper end surface of the screening plate can prevent large aggregate particles from rolling down to the left end of the screening plate, thereby ensuring that the large aggregate particles can be discharged from the discharge port.

As a further improvement of the utility model, the technical problem to be solved is that the dust dropped after screening is easy to float out from the discharge port, causing dust pollution.

In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: a baffle is also installed at the bottom of the end of the screening plate away from the guide rod, the baffle is hinged to the bottom of the screening plate through a pin shaft, and the side wall of the baffle is provided with a protrusion, and the side wall of the screening bin is provided with a sliding groove for facilitating the up and down sliding of the protrusion.

The beneficial effect of the above improvement is: through the setting of the baffle and the cooperation of the protrusion and the slide groove, when the screening plate is in a state of low on the left and high on the right, the baffle at this time can block the discharge port to prevent dust from escaping from the discharge port, and when the screening plate rotates, the baffle at this time descends with the screening plate, thereby not affecting the discharge of aggregate.
