Description

A dust removal and washing system for sand and gravel aggregate production Technical Field

[0001] This invention relates to the field of sand and gravel aggregate production technology, specifically to a sand and gravel aggregate production dust removal and washing system. Background Technology

[0002] Sand and gravel aggregates refer to granular materials that are mixed with cement, water, and other materials to make concrete or mortar in construction projects such as buildings and roads. They are a major component of concrete, and their quality and performance have a crucial impact on many aspects of concrete, including strength and durability. Sand and gravel aggregates mainly consist of natural sand and gravel and manufactured sand and gravel. Natural sand and gravel primarily includes river sand, sea sand, and mountain sand, while manufactured sand and gravel are produced through the processing of mountain rocks, tailings, and construction waste. Regardless of whether they are natural or manufactured, sand and gravel must be washed during their production.

[0003] Chinese Patent Publication No. CN 207204350 U discloses a powder removal and washing system for sand and gravel aggregate production, including multiple water spray pipes and a washing screen. The washing screen is a vibrating washing screen, installed at an angle, with the higher end positioned below the discharge end of the feed belt conveyor and the lower end positioned above the feed end of the discharge conveyor. Multiple water spray pipes are installed side by side above the washing screen and have water spray holes on their lower side.

[0004] The aforementioned sand and gravel aggregate production de-dusturing and washing system utilizes an inclined washing screen to generate vibrations and transfer the sand and gravel aggregates. Simultaneously, multiple water spray pipes above the washing screen spray and wash the sand and gravel aggregates on the screen. However, during the mining and processing of sand and gravel aggregates, their surfaces not only contain easily washable stone powder but also hard impurities that are tightly adhered to the surface and cannot be removed by spraying alone. The aforementioned sand and gravel aggregate production de-dusturing and washing system, which uses multiple water spray pipes to spray the sand and gravel aggregates, can only remove the light stone powder on the sand and gravel aggregates and cannot remove the hard impurities. In addition, when a batch of sand and gravel aggregates is poured onto the washing screen, the multiple water spray pipes can only spray the top layer of sand and gravel aggregates, while the sand and gravel aggregates at the bottom cannot be fully washed, resulting in incomplete removal of impurities from the sand and gravel aggregates and poor washing effect. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a sand and gravel aggregate production dust removal and washing system. After the sand and gravel aggregate enters the water outlet pipe, water mixes with the sand and gravel aggregate and enters the grinding mechanism together. The sand and gravel aggregate moves rapidly in the grinding mechanism and generates friction with the grinding mechanism, thereby removing hard impurities and light stone powder. Furthermore, 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, thus solving the above-mentioned technical problems.

[0022] Beneficial effects:

[0023] A. In this invention, firstly, water pump one draws water from the water tank into the water outlet pipe through the inlet pipe. Simultaneously, the sand and gravel aggregate in the sand and gravel aggregate storage device enters the water outlet pipe through the feed pipe and mixes with the water. Then, the water mixed with the sand and gravel aggregate enters the volute feed bin one through the water outlet pipe, and then enters the cylinder through the volute feed bin one. The motor, in conjunction with the reducer, drives the drive shaft to rotate. The drive shaft synchronously drives the plum blossom seat and the second chassis to rotate. Multiple oblique cutters follow the rotation of the second chassis, and during the rotation, they scoop up the sand and gravel aggregate settled on the top of the first chassis, and agitate the water flow, causing the sand and gravel aggregate to roll rapidly in the water flow, thus the water flow... The flow rate of water on the surface of the sand and gravel aggregate allows the water to quickly wash the aggregate. Multiple grinding rollers rotate rapidly following the plum blossom seat. These rollers, in conjunction with the grinding ring, grind the sand and gravel aggregate located between them. The friction removes hard impurities from the aggregate. Combined with the water flow, this effectively removes both light and hard impurities from the surface of the aggregate, improving the cleaning effect. After the cleaning process is complete, opening the sealed door allows for the removal of impurities from the volute feed hopper and the cylinder. The sealed door also facilitates the maintenance and replacement of the grinding rollers and the angled blades.

[0024] B. In this invention, the water in the cylinder continuously rises and enters the discharge pipe. Then, the water mixed with sand and gravel aggregate enters the connecting pipe through the discharge pipe, then enters the volute feed bin II through the connecting pipe, and finally enters the centrifuge cylinder through the volute feed bin II. Simultaneously, the second water pump operates to rapidly pump water from the water tank into the volute feed bin II, thereby increasing the flow rate and velocity of the water in the volute feed bin II. The rapid flow of water in the volute feed bin II and the centrifuge cylinder generates vortices and a centrifugal effect (the cyclone centrifuge mechanism is existing technology, and its working principle will not be elaborated here). During the centrifugal effect... Under the action of the system, the sand and gravel aggregates move towards the dispersing nozzle, while some of the water flows into the U-shaped pipe. The sand and gravel aggregates, along with some of the water, are sprayed into the screening mechanism through the dispersing nozzle. The dispersing nozzle is equipped with an inclined trapezoidal plate, which can disperse the water flow concentrated at the centrifuge outlet and shorten the spray distance, ensuring that the water and sand and gravel aggregates can accurately fall into the screening mechanism. In addition, the water flow speed in the volute feed bin and the centrifuge is relatively fast, resulting in a greater impact force on the surface of the sand and gravel aggregates, which can further clean the sand and gravel aggregates, thereby further increasing the cleaning effect of the sand and gravel aggregates.

[0025] C. In this invention, while water mixed with sand and gravel aggregate is sprayed onto the screen plate, multiple vibrating motors generate vibration, causing the screen bin and screen plate to shake. Multiple springs can increase the shaking amplitude of the screen bin and screen plate. The screen plate can block the sand and gravel aggregate, while the water flows through the screen holes of the screen plate into the water tank. When the screen plate shakes rapidly, it can drive the sand and gravel aggregate to move in the direction of the guide frame plate, thereby removing the sand and gravel aggregate from the screen bin. The airflow generated by the blower blows towards the screen plate through two air outlet pipes. The airflow can blow away the water stains on the surface of the sand and gravel aggregate, increasing the drying speed of the sand and gravel aggregate. At the same time, the airflow can also blow out the sand and gravel aggregate stuck in the screen holes of the screen plate, preventing the sand and gravel aggregate from clogging the screen holes.

[0026] D. In this invention, water flowing through the sieve holes of the sieve plate falls into the water tank for storage, while water entering the U-shaped pipe from the volute feed bin II enters the silo body and the outlet chamber for storage. During operation, water pumps II and I pump water out of the tank, thus achieving water reuse and reducing water consumption in sand and gravel aggregate washing. When the water tank is full, the float rises with the water level and controls the rotating rod to rotate clockwise around the connecting piece I, causing the sealing plate to fit tightly against the bottom of the outlet chamber. The sealing plate blocks the outlet chamber, preventing water from entering the silo body and the outlet chamber. In the water tank; when the water level in the tank is insufficient, the float descends with the water level in the tank and controls the rotating rod to rotate counterclockwise and descend, while simultaneously driving the sealing plate to rotate counterclockwise around the connecting piece two, thereby allowing water from the tank body and water chamber to enter the water tank, ensuring that there is enough water in the tank for water pump two and water pump one; in addition, both water inlets two are connected to a water source, and when all the water stored in the tank body and water outlet chamber is still insufficient, water from an external water source can be guided into the tank body and water outlet chamber through the two water inlets two, ensuring that the tank body and water outlet chamber can provide sufficient water to the water tank.

Detailed Implementation

[0052] Please refer to Figures 1-5 and 14-15. A sand and gravel aggregate production dust removal and washing system includes a grinding mechanism 1, whose inlet end is fixedly connected to a water pump assembly 3 and whose outlet end is fixedly connected to a cyclone centrifugal mechanism 2; the cyclone centrifugal mechanism 2 is fixedly connected to a water pump 4, and a screening mechanism 5 is provided below the end of the cyclone centrifugal mechanism 2 away from the grinding mechanism 1; a water tank mechanism 6 is provided below the screening mechanism 5, and a water replenishment mechanism 8 is provided below the cyclone centrifugal mechanism 2;

[0053] The water pump assembly 3 includes a water pump 31, the inlet end of which is fixedly connected to an inlet pipe 32 and the outlet end of which is fixedly connected to an outlet pipe 33; the end of the inlet pipe 32 away from the water pump 31 is fixedly connected to a water tank mechanism 6, the end of the outlet pipe 33 away from the water pump 31 is fixedly connected to a grinding mechanism 1, and the top of the middle section of the outlet pipe 33 is fixedly connected to a feed pipe 34, the end of the feed pipe 34 away from the outlet pipe 33 is fixedly connected to a sand and gravel aggregate storage device.

[0054] The cyclone centrifuge mechanism 2 includes a spiral feed bin 21, one end of which is provided with a connecting pipe 24, and the connecting pipe 24 is fixedly connected to the grinding mechanism 1; the end of the spiral feed bin 21 away from the connecting pipe 24 is provided with a water inlet 26, which is fixedly connected to the outlet end of the water pump 4 through a pipe, and the inlet end of the water pump 4 is fixedly connected to the water tank mechanism 6 through a pipe; the middle of the side of the spiral feed bin 21 near the grinding mechanism 1 is fixedly connected to the end of the U-shaped tube 25, and the side of the spiral feed bin 21 away from the U-shaped tube 25 is fixedly connected to the centrifuge cylinder 22, and the end of the centrifuge cylinder 22 away from the spiral feed bin 21 is fixedly connected with a dispersing nozzle 23;

[0055] By adopting the above technical solution, the water in the cylinder 12 continuously rises and enters the discharge pipe 13. Then, the water mixed with sand and gravel aggregate enters the connecting pipe 24 through the discharge pipe 13, and then enters the volute feed bin 21 through the connecting pipe 24. Finally, it enters the centrifuge cylinder 22 through the volute feed bin 21. At the same time, the water pump 24 operates to quickly pump the water in the water tank 61 into the volute feed bin 21, thereby increasing the flow rate and velocity of the water in the volute feed bin 21. When the water flows rapidly in the volute feed bin 21 and the centrifuge cylinder 22, it will generate vortices and produce a centrifugal effect. The cyclone centrifuge mechanism is existing technology, and its working principle will not be described in detail here. Under the centrifugal effect, the sand and gravel aggregates move towards the dispersing nozzle 23, while some of the water flows into the U-shaped pipe 25. The sand and gravel aggregates, along with some water, are sprayed into the screening mechanism 5 through the dispersing nozzle 23. The dispersing nozzle 23 is equipped with an inclined trapezoidal plate, which disperses the concentrated water flow from the centrifuge cylinder 22 outlet, while shortening the water spray distance, ensuring that the water and sand and gravel aggregates accurately fall into the screening mechanism 5. Furthermore, the water flow velocity in the volute feed bin 21 and the centrifuge cylinder 22 is relatively high, resulting in a greater impact on the surface of the sand and gravel aggregates, further cleaning them and thus increasing the cleaning effect.

[0056] Please refer to Figures 1-2, 8, and 14-22.

[0058] The grinding assembly 18 includes a chassis 181, which is coaxially arranged with the volute feed chamber 11 and sealed and fixedly connected to the bottom of the volute feed chamber 11; a drive shaft 184 is rotatably connected to the middle of the chassis 181, the bottom of the drive shaft 184 is located below the chassis 181 and fixedly connected to the output end of the reducer 16, and a perforated seat 185 is fixedly connected to the top of the drive shaft 184;

[0059] Multiple fixing members 186 are evenly fixedly connected to the plum blossom seat 185, and the multiple fixing members 186 are arranged in a ring. The multiple fixing members 186 are respectively fixedly connected to the top of multiple connecting rollers 187, and the lower end of each of the multiple connecting rollers 187 is rotatably connected to a grinding roller 188. A grinding ring 182 is coaxially provided above the chassis 181. The top of the grinding ring 182 is fixedly connected to the top inner wall of the volute feed hopper 11, and the multiple grinding rollers 188 are all located inside the grinding ring 182.

[0060] The grinding ring 182 is provided with a plurality of baffles 183 evenly on its outer side and the plurality of baffles 183 are arranged in a ring.

[0061] By adopting the above technical solution, firstly, water pump 31 pumps water from water tank 61 into water outlet pipe 33 through inlet pipe 32. At the same time, sand and gravel aggregate in the sand and gravel aggregate storage equipment enters water outlet pipe 33 through feed pipe 34 and mixes with water. Then, the water mixed with sand and gravel aggregate enters volute feed bin 11 through water outlet pipe 33, and then enters cylinder 12 through volute feed bin 11. Motor 17, in conjunction with reducer 16, drives drive shaft 184 to rotate. Drive shaft 184 synchronously drives plum blossom seat 185 and chassis 189 to rotate. Multiple inclined blades 180 follow chassis 189 to rotate, and during the rotation, they scoop up the sand and gravel aggregate settled on top of chassis 181 and agitate the water flow, allowing the sand and gravel aggregate to move in the water flow. The rapid rolling motion increases the flow speed of water on the surface of the sand and gravel aggregate, allowing the water to quickly wash the aggregate. Multiple grinding rollers 188 rotate rapidly following the plum blossom seat 185. The multiple grinding rollers 188, in conjunction with the grinding ring 182, can grind the sand and gravel aggregate located between the grinding rollers 188 and the grinding ring 182. Through friction, hard impurities on the sand and gravel aggregate are removed. Combined with the washing of the sand and gravel aggregate by the water flow, both light and hard impurities on the surface of the sand and gravel aggregate can be removed, improving the cleaning effect. After the sand and gravel aggregate cleaning work is completed, opening the sealing door 15 allows the impurities in the volute feed bin 11 and the cylinder 12 to be cleaned. The sealing door 15 also facilitates the maintenance and replacement of the grinding rollers 188 and the oblique blades 180.

[0062] Please refer to Figures 6-9. In this embodiment, the screening mechanism 5 includes a screening chamber 51. A screen plate 52 is fixedly connected to the bottom inner side of the screening chamber 51. The screen plate 52 is evenly provided with a plurality of screen holes.

One end of each of the multiple connecting seats 55 is fixedly connected to the outer ends of both ends of the screen chamber 51, and the bottoms of the multiple connecting seats 56 are fixedly connected to the tops of the two bridge frames 58. Two air outlet pipes 59 are symmetrically provided at the end of the screen chamber 51 away from the vibrating motor 54.

A guide frame plate 50 is fixedly connected to the end of the screen chamber 51 away from the air outlet pipes 59 by bolts.

[0064] By adopting the above technical solution, while water mixed with sand and gravel aggregate is sprayed onto the screen plate 52, multiple vibrating motors 54 generate vibration, and then the screen bin 51 and the screen plate 52 shake. Multiple springs 57 can increase the shaking amplitude of the screen bin 51 and the screen plate 52. The screen plate 52 can block the sand and gravel aggregate, while the water flows through the screen holes of the screen plate 52 and falls into the water tank 61. When the screen plate 52 shakes rapidly, it can drive the sand and gravel aggregate to move in the direction of the guide frame plate 50, thereby moving the sand and gravel aggregate out of the screen bin 51. The airflow generated by the blower blows towards the screen plate 52 through two air outlet pipes 59. The airflow can blow away the water stains on the surface of the sand and gravel aggregate, increasing the drying speed of the sand and gravel aggregate. At the same time, the airflow can also blow out the sand and gravel aggregate stuck in the screen holes of the screen plate 52, preventing the sand and gravel aggregate from clogging the screen holes.

[0065] Please refer to Figure 3-14. In this embodiment, the water replenishment mechanism 8 includes a water replenishment chamber 81, and a floating component 82 is provided below the water replenishment chamber 81. The water replenishment chamber 81 includes a chamber body 811. The end of the U-shaped tube 25 away from the volute feed chamber 21 is fixedly connected to the chamber body 811. The bottom of the chamber body 811 is fixedly connected to the water outlet chamber 813. Two connectors 814 are symmetrically provided at one end of the water outlet chamber 813, and two connectors 815 are symmetrically provided at the other end. Water inlets 812 are provided at both ends of the chamber body 811.

[0066] The floating assembly 82 includes a float body 821, with rotating rods 822 fixedly connected to both ends of the float body 821. The ends of the two rotating rods 822 away from the float body 821 are rotatably connected to two connecting parts 814. A spring 824 is provided between the float body 821 and the tank body 811. One end of the spring 824 is fixedly connected to a connecting rod 823, and the other end is fixedly connected to a connecting part 825. The connecting part 825 is fixedly connected to the tank body 811. The two ends of the connecting rod 823 are... The connecting rod 823 is fixedly connected to the two rotating rods 822; a connecting rod 826 is provided on the side of the connecting rod 823 away from the float body 821. The two ends of the connecting rod 826 are fixedly connected to the two rotating rods 822 respectively, and auxiliary parts 827 are fixedly connected to both ends of the connecting rod 826; the ends of the two auxiliary parts 827 away from the connecting rod 826 are fixedly connected to the two sides of the sealing plate 828 respectively, and the two sides of the ends of the sealing plate 828 away from the auxiliary parts 827 are rotatably connected to the two connecting parts 815 respectively.

[0067] The water tank mechanism 6 includes a water tank 61, with support legs 62 fixedly connected to the four outer corners of the water tank 61. The bottoms of the support legs 62 are fixedly connected to the top of the base frame 7. Platforms 63 are fixedly connected to the outer sides of the middle section of the water tank 61. Water outlets 64 are provided on both sides of the lower end of the water tank 61. The end of the inlet pipe 32 away from the first water pump 31 and the end of the inlet pipe of the second water pump 4 away from the second water pump 4 are fixedly connected to the two water outlets 64 respectively. The second water pump 4 is fixedly connected to the top of one of the platforms 63. The water outlet chamber 813 and the float body 821 are both located inside the water tank 61.

[0068] By adopting the above technical solution, water flowing through the sieve holes of the sieve plate 52 falls into the water tank 61 and is stored in the water tank 61. Water entering the U-shaped pipe 25 from the spiral feed bin 21 enters the bin body 811 and the outlet bin 813 for storage. When the water pump 2 4 and the water pump 1 31 are operating, they draw water out of the water tank 61, thereby realizing water reuse and reducing the water consumption for sand and gravel aggregate washing. When the water tank 61 is full, the float 821 rises with the water level in the water tank 61 and controls the rotating rod 822 to rotate clockwise around the connector 1 814, thereby making the sealing plate 828 fit tightly against the bottom of the outlet bin 813. The sealing plate 828 can block the outlet bin 813, preventing water from entering the water tank from the bin body 811 and the outlet bin 813. In tank 61, when the water level in tank 61 is insufficient, the float 821 descends with the water level in tank 61 and controls the rotating rod 822 to rotate counterclockwise and descend. At the same time, it drives the sealing plate 828 to rotate counterclockwise around the connecting piece 815, thereby allowing water from the tank body 811 and the water tank 813 to enter the water tank 61, ensuring that the water in the water tank 61 is sufficient for the use of water pump 4 and water pump 31. In addition, both water inlets 812 are connected to a water source. When all the water stored in the tank body 811 and the outlet tank 813 enters the water tank 61 and is still insufficient, water from an external water source can be guided into the tank body 811 and the outlet tank 813 through the two water inlets 812, ensuring that the tank body 811 and the outlet tank 813 can provide sufficient water to the water tank 61.
