Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel aggregate production, and in particular to a sand and gravel aggregate production powder removal and water washing system. Background Art

[0002] Aggregate refers to the granular material that is mixed with cement, water and other materials to make concrete or mortar in the construction of buildings, roads and other projects. It is the main component of concrete, and its quality and performance have a key impact on the strength, durability and many other aspects of concrete; Aggregate mainly includes natural sand and gravel and machine-made sand and gravel. Natural sand and gravel mainly include river sand, sea sand and mountain sand, while machine-made sand and gravel are produced through the processing of mountain rocks, tailings, construction waste, etc. Whether it is natural sand and gravel or machine-made sand and gravel, it needs to be cleaned when it is produced.

[0003] Chinese patent publication number CN 207204350 U discloses a sand and gravel aggregate production powder removal and water washing system, comprising a plurality of water spray pipes and a water washing screen, wherein the water washing screen adopts a vibrating water washing screen, which is installed obliquely, with the high end being placed below the discharge end of the feed belt conveyor, and the low end being located above the feed end of the discharge conveyor, and the plurality of water spray pipes being installed side by side above the water washing screen and having water spray holes arranged on the lower side thereof;

[0004] The above-mentioned sand and gravel aggregate production powder removal and water washing system utilizes an inclined water washing screen to generate vibration to transport sand and gravel aggregates, and at the same time, multiple water spray pipes above the water washing screen spray and wash the sand and gravel aggregates on the water washing screen; however, during the mining and processing of sand and gravel aggregates, there are not only easy-to-clean stone powder on the surface of the sand and gravel aggregates, but also hard impurities that are tightly adhered to the surface of the sand and gravel aggregates and cannot be removed by spraying alone; the above-mentioned sand and gravel aggregate production powder removal and water washing system utilizes multiple water spray pipes to spray the sand and gravel aggregates, which can only remove the light stone powder on the sand and gravel aggregates, but cannot remove the hard impurities. In addition, when the batches of sand and gravel aggregates are poured onto the water washing screen, the multiple water spray pipes can only spray the uppermost layer of sand and gravel aggregates, and the sand and gravel aggregates at the bottom cannot be fully cleaned, resulting in incomplete removal of impurities in the sand and gravel aggregates and poor water washing effect. Summary of the invention

[0005] Technical issues to be solved

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, meet the actual needs, and provide a sand and gravel aggregate production powder removal and water washing system. After the sand and gravel aggregate enter the water outlet pipe, the water and the sand and gravel aggregate are mixed and enter the grinding mechanism together. The sand and gravel aggregate moves rapidly in the grinding mechanism and generates friction with the grinding mechanism to remove hard impurities and light stone powder. In addition, the sand and gravel aggregate and water are fully mixed in the grinding mechanism and the cyclone centrifugal mechanism to ensure that the sand and gravel aggregate can be completely cleaned, so as to solve the above technical problems.

[0022] Beneficial effects:

[0023] A. In the present invention, firstly, the water pump 1 pumps the water in the water tank into the water outlet pipe through the water inlet pipe, and at the same time, the sand and gravel aggregates in the sand and gravel aggregate storage device enter the water outlet pipe through the feed pipe and mix with the water, and then the water mixed with the sand and gravel aggregates enters the volute feed bin 1 through the water outlet pipe, and enters the cylinder through the volute feed bin 1; the motor cooperates with the reducer to drive the transmission shaft to rotate, and the transmission shaft synchronously drives the plum blossom seat and the chassis 2 to rotate, and a plurality of inclined knives rotate with the chassis 2, and during the rotation, the sand and gravel aggregates deposited on the top of the chassis 1 are shoveled up, and the water flow is stirred to make the sand and gravel aggregates roll quickly in the water flow, so that the water flow The flow speed on the surface of the sand and gravel aggregate allows the water flow to quickly flush the sand and gravel aggregate; multiple grinding rollers rotate rapidly with the plum blossom seat, and multiple grinding rollers cooperate with the grinding ring to grind the sand and gravel aggregate between the grinding rollers and the grinding ring, and remove the hard impurities on the sand and gravel aggregate through friction. With the flushing of the sand and gravel aggregate by the water flow, all light and hard impurities on the surface of the sand and gravel aggregate can be removed, thereby improving the cleaning effect of the sand and gravel aggregate; after the sand and gravel aggregate cleaning work is completed, the impurities in the volute feed bin and the cylinder can be cleaned up by opening the sealing door, and the grinding rollers and bevel knives can also be easily repaired and replaced through the sealing door;

[0024] B. In the present invention, the water in the cylinder rises continuously and enters the discharge pipe, and then the water mixed with sand and gravel aggregate enters the connecting pipe through the discharge pipe, and then enters the volute feed bin 2 through the connecting pipe, and finally enters the centrifugal cylinder through the volute feed bin 2; at the same time, the water pump 2 operates to quickly pump the water in the water tank into the volute feed bin 2, thereby increasing the flow rate and flow velocity of the water in the volute feed bin 2. When the water flow in the volute feed bin 2 and the centrifugal cylinder flows rapidly, vortices will be generated and centrifugal effect will be generated (the cyclone centrifugal mechanism is a prior art, and its working principle will not be repeated here). Under the action of the water, the sand and gravel aggregates move toward the dispersion nozzle, and part of the water flows into the U-shaped tube; the sand and gravel aggregates are sprayed into the screening mechanism through the dispersion nozzle together with part of the water flow. The dispersion nozzle is provided with an inclined trapezoidal plate, which can disperse the water flow concentratedly sprayed from the outlet of the centrifugal cylinder and shorten the spraying distance of the water flow, ensuring that the water flow and the sand and gravel aggregates can accurately fall into the screening mechanism; in addition, the water flow speed in the volute feed bin 2 and the centrifugal cylinder is relatively fast, and the impact force on the surface of the sand and gravel aggregates is relatively large, which can further clean the sand and gravel aggregates, thereby further increasing the cleaning effect of the sand and gravel aggregates;

[0025] C. In the present invention, when the water mixed with sand and gravel aggregates is sprayed onto the sieve plate, multiple vibration motors generate vibrations, and then the sieve bin and the sieve plate generate shaking. Multiple springs can increase the shaking amplitude of the sieve bin and the sieve plate, and the sieve plate can block the sand and gravel aggregates. The water flows into the water tank through the sieve holes of the sieve plate. When the sieve plate shakes rapidly, it can drive the sand and gravel aggregates to move in the direction of the material guide frame plate, thereby moving the sand and gravel aggregates out of the sieve bin; the airflow generated by the fan is blown toward the sieve plate through two air outlet pipes, and the airflow can blow away the water stains on the surface of the sand and gravel aggregates, thereby increasing the drying speed of the sand and gravel aggregates. At the same time, the airflow can also blow out the sand and gravel aggregates stuck in the sieve holes of the sieve plate, thereby preventing the sand and gravel aggregates from clogging the sieve holes.

[0026] D. In the present invention, water flows through the sieve holes of the sieve plate and falls into the water tank and is stored in the water tank. Water from the volute feed bin 2 that enters the U-shaped tube enters the bin body and the water outlet bin for storage. When the water pump 2 and the water pump 1 are in operation, the water in the water tank is pumped away, thereby realizing the reuse of water and reducing the water consumption for sand and gravel aggregate cleaning. When the water volume in the water tank is sufficient, the float rises with the water level in the water tank, and controls the rotating rod to rotate and rise clockwise with the connecting piece 1 as the center, so that the sealing plate fits tightly with the bottom of the water outlet bin, and the sealing plate can block the water outlet bin, so that the water in the bin body and the water outlet bin will not enter. into the water tank; when the water amount in the water tank is insufficient, the float body drops along with the water level in the water tank, and controls the rotating rod to rotate counterclockwise and drop, and at the same time drives the sealing plate to rotate counterclockwise with the connecting piece 2 as the center, so that the water in the warehouse body and the water tank enters the water tank, ensuring that the water in the water tank is sufficient for water pump 2 and water pump 1 to use; in addition, the two water filling ports are both connected to the water source. When the water stored in the warehouse body and the water outlet warehouse all enters the water tank and is still insufficient for use, the water in the external water source can be guided into the warehouse body and the water outlet warehouse through the two water filling ports, ensuring that the warehouse body and the water outlet warehouse can provide sufficient water to the water tank.
