Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a phosphogypsum recycled aggregate crusher. Background Art

[0002] Phosphogypsum recycled aggregate is an aggregate made from phosphogypsum solid waste through a specific process. It is mainly used to replace natural aggregate as a construction material. In the processing of phosphogypsum recycled aggregate, phosphogypsum and other raw materials need to be dehydrated, crushed, ground, mixed and granulated, and a crusher is needed in the crushing stage.

[0003] The utility model patent with authorization announcement number CN112973867A discloses a construction aggregate crushing device, which includes a workbench, a plurality of supporting legs are fixedly connected to the bottom of the workbench, a fixed base is fixedly connected to the bottom of the supporting legs, a crushing barrel is fixedly connected to the workbench, a feed port is provided at the upper end of the crushing barrel, a discharge port is provided at the bottom of the crushing barrel, a driving motor is fixedly installed on the side wall of the crushing barrel, a crushing shaft is fixedly installed on the output end of the driving motor, a plurality of crushing teeth are fixedly connected to the crushing shaft, and construction aggregates to be crushed are poured into the feed port, and the crushing shaft can be driven to rotate by the driving motor, and the construction aggregates can be driven to rotate in the crushing barrel, and a plurality of transmission mechanisms are fixedly provided on the side wall of the crushing barrel. The building aggregates inside the crushing cylinder can squeeze the elastic plate, drive the elastic plate to move inward, drive the movable rod to contract, cause the reset frame to deform, squeeze the elastic wall, and transport the gas inside the extrusion chamber to the air pressure chamber through the connecting pipe. The air pressure inside the air pressure chamber increases, which can drive the telescopic rod to move outward. In the process of the telescopic rod moving outward, the piston rod can compress the gas inside the piston chamber, so that the limit block is stuck in the card, which can limit the reset of the telescopic rod. While the crushing shaft squeezes the building aggregate, the limit rod can limit the position of the building aggregate, which can prevent the building aggregate from splashing during the crushing process and improve the crushing efficiency.

[0004] Although the construction aggregate crushing device can improve the crushing efficiency of aggregates, the device still has the following problems in actual use: when crushing aggregates, due to the particularity of the raw materials, a large amount of dust particles will be generated in the crushing process, and the feed port and the discharge port of the device are both open during crushing, and are not designed to be closed or dust removed. Therefore, the dust particles generated by the crushing will inevitably spread to the outside through the feed port and the discharge port. Dust and other pollutants are very harmful to the human body and the working environment. In view of this, we propose a phosphogypsum recycled aggregate crusher. Utility Model Content

[0042] It is worth noting that the first motor 15 and the second motor 23 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0043] Before specific use, the user first turns on the power of the first motor 15, and the first motor 15 starts to work. The output shaft of the first motor 15 drives the screw rod 13 to rotate. As the screw rod 13 rotates, the connecting plate 16 and the connecting seat 17 move upward, and the connecting plate 16 drives the support plates 18 on both sides to move upward at the same time. At the same time, the support plate 18 drives the cover plate 19 to flip upward, and the feed port 10 is exposed. Then the user puts the raw materials into the feed hopper 1. Next, the user turns on the power of the first motor 15 again, and the first motor 15 starts to work. The output shaft of the first motor 15 drives the screw rod 13 to rotate in the opposite direction, and the connecting plate 16 and the connecting seat 17 move downward. The connecting plate 16 drives the support plates 18 on both sides to move downward at the same time. At the same time, the support plate 18 drives the cover plate 19 to flip downward. When the cover plate 19 covers the feed port 10, the user stops the power of the first motor 15.

[0044] During specific use, the user first turns on the power of the second motor 23 and the exhaust fan 33, and the second motor 23 and the exhaust fan 33 start working. The output shaft of the second motor 23 drives the crushing roller 20 to rotate. Because the two gears 22 are meshed, the two crushing rollers 20 rotate synchronously relative to each other. Under the rotation of the crushing rollers 20, the raw materials can be crushed. The crushed raw materials fall into the box body 30 and fall into the collection frame 34. At the same time, under the action of the exhaust fan 33, the dust in the box body 30 enters the filter chamber 302 through the connecting grooves 304 on both sides. The dust passes through the filter screen 311 at the same time and is intercepted and filtered by the filter screen 311, and the filtered gas is discharged to the outside.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
