Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sand and gravel washing equipment, specifically to a washing device for washing quartz sand. Background Technology
[0002] Quartz sand is an important industrial raw material, widely used in glass manufacturing, foundry, building materials, water treatment, and electronics industries. Its production process mainly includes mining, crushing, screening, washing, and drying. However, the surface of screened quartz sand still contains a significant amount of mud and sand. Therefore, the conventional quartz sand washing process involves scrubbing to remove mud, acid leaching to remove impurities, and rinsing to remove acid. In actual production, the scrubbed and deslimed quartz sand is directly added to the acid washing tank. However, for coarse sand with a larger particle size, a large amount of water adheres after scrubbing and desliming, causing the concentration of the newly added acidic solution to decrease rapidly, thus affecting the acid washing effect of the quartz sand. Utility Model Content
[0003] To address the technical problem of rapid decrease in the concentration of acid washing solution caused by directly immersing quartz sand after scrubbing and desliming, this invention provides a washing device for cleaning quartz sand. A slope dewatering mechanism is installed between the scrubbing machine and the acid washing tank. The quartz sand is rolled into the acid washing tank along the slope dewatering mechanism to remove most of the water adhering to the quartz sand before it is immersed in the acid washing tank, thereby avoiding a rapid decrease in the concentration of the acid solution in the acid washing tank and ensuring the acid washing effect of the quartz sand.
[0004] This utility model is achieved through the following technical solution:
[0005] This utility model provides a washing device for cleaning quartz sand, comprising: a scrubbing machine for scrubbing quartz sand and having a discharge port for discharging quartz sand from the scrubbing machine after scrubbing; an acid washing tank for holding an acidic solution; and a slope dewatering mechanism disposed between the scrubbing machine and the acid washing tank, inclined from the scrubbing machine toward the acid washing tank, capable of receiving the quartz sand output from the scrubbing machine; wherein the quartz sand output from the scrubbing machine falls onto the upper end of the slope dewatering mechanism and rolls down into the acid washing tank via the slope dewatering mechanism.
[0006] The washing device for cleaning quartz sand provided by this utility model includes a scrubbing machine, an acid washing tank, and a slope dewatering mechanism. The scrubbing machine can scrub the coarse sand after screening and is equipped with a discharge port to discharge the scrubbed quartz sand. The slope dewatering mechanism is located between the scrubbing machine and the acid washing tank, and is inclined towards the acid washing tank to receive the quartz sand output by the scrubbing machine. Thus, the quartz sand output by the scrubbing machine falls onto the upper end of the slope dewatering mechanism and is guided by the slope dewatering mechanism to roll into the acid washing tank for acid washing. When the quartz sand rolls on the slope dewatering mechanism, the quartz sand particles roll rapidly, causing the water attached to the quartz sand particles to be separated from the quartz sand particles under the action of centrifugal force. This removes most of the water attached to the quartz sand before it is put into the acid washing tank, thereby preventing the concentration of the acid solution in the acid washing tank from decreasing rapidly and ensuring the acid washing effect of the quartz sand.
[0007] In an optional embodiment, the scrubbing machine includes: a cleaning cylinder for holding clean water and a drain outlet at the bottom; a scrubbing paddle installed inside the cleaning cylinder to agitate the clean water and quartz sand inside the cleaning cylinder; and a baffle filter plate disposed at the lower end of the cleaning cylinder, dividing the inner cavity of the cleaning cylinder into a cleaning chamber and a sedimentation chamber from top to bottom; wherein the discharge outlet is disposed on the side wall of the cleaning chamber, and the baffle filter plate is inclined toward the discharge outlet.
[0008] Therefore, when the washing cylinder contains clean water and quartz sand, the baffle plate traps the quartz sand within the washing chamber, while the scrubbing paddle agitates the clean water and quartz sand inside the washing cylinder for scrubbing. The resulting muddy water settles in the sedimentation chamber, facilitating rapid separation of wastewater and quartz sand. After washing, the wastewater can be discharged from the drain outlet, while the quartz sand, guided by the baffle plate, is discharged from the discharge outlet, achieving rapid separation of wastewater and quartz sand. This allows the quartz sand to be immediately sent to the pickling tank for pickling after washing, avoiding prolonged settling which would affect production efficiency.
[0009] In an alternative embodiment, the drain outlet is adapted with a drain valve to facilitate control of the opening and closing of the drain outlet.
[0010] In an optional embodiment, the discharge port is adapted with a discharge valve to facilitate control of the opening and closing of the discharge port.
[0011] In an optional embodiment, both the drain valve and the discharge valve are gate valves to ensure that both the drain outlet and the discharge outlet have sufficient material flow capacity.
[0012] In an optional embodiment, the inclined dewatering mechanism includes a roller plate; the roller plate is inclined from the scrubbing machine toward the pickling tank, and the upper end of the roller plate is located below the discharge port and the lower end extends to the pickling tank; the roller plate array is provided with a plurality of filter holes so that the quartz sand particles can roll on the inclined dewatering mechanism and discharge the separated water.
[0013] In an optional embodiment, baffles are provided on both sides of the rolling plate along its length to prevent the sides of the long rolling plate from falling off when the quartz sand particles roll on the rolling plate.
[0014] In an optional embodiment, the rolling plate is provided with a plurality of arc-shaped protrusions; the arc-shaped protrusions are arranged along the width direction of the rolling plate, and the plurality of arc-shaped protrusions are spaced apart along the length direction of the rolling plate, so as to force the quartz sand to roll under the action of gravity through the blocking effect of the arc-shaped protrusions, thereby preventing the quartz sand particles from sliding directly relative to each other on the rolling plate and thus failing to dehydrate quickly.
[0015] In an optional embodiment, the inclined dewatering mechanism further includes a deceleration plate, one side of which is connected to the lower end of the rolling plate and the other side is higher than the lower end of the rolling plate. The deceleration plate is located above the pickling tank so that the quartz sand particles rolling off the rolling plate roll upward along the deceleration plate before entering the pickling tank, thus avoiding excessive kinetic energy of the quartz sand that could cause the pickling solution in the pickling tank to splash.
[0016] In an optional embodiment, the deceleration plate and the rolling plate are connected by an arc-shaped transition plate to ensure that the quartz sand can roll from the rolling plate to the deceleration plate and avoid the quartz sand accumulating between the deceleration plate and the rolling plate.
[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0018] The washing device for cleaning quartz sand provided by this utility model includes a scrubbing machine, an acid washing tank, and a slope dewatering mechanism. The scrubbing machine can scrub the coarse sand after screening and is equipped with a discharge port to discharge the scrubbed quartz sand. The slope dewatering mechanism is located between the scrubbing machine and the acid washing tank, and is inclined towards the acid washing tank to receive the quartz sand output by the scrubbing machine. Thus, the quartz sand output by the scrubbing machine falls onto the upper end of the slope dewatering mechanism and is guided by the slope dewatering mechanism to roll into the acid washing tank for acid washing. When the quartz sand rolls on the slope dewatering mechanism, the quartz sand particles roll rapidly, causing the water attached to the quartz sand particles to be separated from the quartz sand particles under the action of centrifugal force. This removes most of the water attached to the quartz sand before it is put into the acid washing tank, thereby preventing the concentration of the acid solution in the acid washing tank from decreasing rapidly and ensuring the acid washing effect of the quartz sand.

[0033] Example
[0034] Combination Figure 1 and Figure 2 This embodiment provides a washing device for cleaning quartz sand, including: a scrubbing machine 10 for scrubbing quartz sand and having a discharge port 11, which can discharge the quartz sand in the scrubbing machine 10 after scrubbing; an acid washing tank 20 for holding an acidic solution; and a slope dewatering mechanism 30 disposed between the scrubbing machine 10 and the acid washing tank 20, and inclined from the scrubbing machine 10 toward the acid washing tank 20, capable of receiving the quartz sand output by the scrubbing machine 10; wherein the quartz sand output by the scrubbing machine 10 falls onto the upper end of the slope dewatering mechanism 30, and rolls down into the acid washing tank 20 through the slope dewatering mechanism 30.
[0035] Recombined Figure 1 The scrubbing machine 10 includes: a cleaning cylinder 12 for holding clean water, with a drain outlet 13 at the bottom; a scrubbing paddle 14 installed inside the cleaning cylinder 12, capable of agitating the clean water and quartz sand inside the cleaning cylinder 12; and a baffle filter plate 15 disposed at the lower end of the cleaning cylinder 12, dividing the inner cavity of the cleaning cylinder 12 from top to bottom into a cleaning chamber 16 and a sedimentation chamber 17; wherein, the discharge port 11 is disposed on the side wall of the cleaning chamber 16, and the baffle filter plate 15 is inclined toward the discharge port 11.
[0036] Therefore, when the cleaning cylinder 12 contains clean water and quartz sand, the baffle plate 15 traps the quartz sand in the cleaning chamber 16, while the scrubbing paddle 14 agitates the clean water and quartz sand in the cleaning cylinder 12 for scrubbing. The muddy water generated during scrubbing settles in the sedimentation chamber 17, facilitating the rapid separation of wastewater and quartz sand. After cleaning, the wastewater can be discharged from the drain outlet 13, while the quartz sand, guided by the baffle plate 15, is discharged from the discharge outlet 11, achieving rapid separation of wastewater and quartz sand. This allows the quartz sand to be immediately sent to the pickling tank 20 for pickling after cleaning, avoiding prolonged settling which would affect production efficiency.
[0037] The scrubbing paddles 14 are mounted on top of the cleaning cylinder 12 via mounting brackets, and multiple paddles are arranged in descending order along the inclined direction of the baffle filter plate 15. The depth to which the multiple scrubbing paddles 14 extend into the cleaning cylinder 12 increases sequentially along the inclined direction of the baffle filter plate 15. Simultaneously, the blades of the scrubbing paddles 14 are arranged parallel to the baffle filter plate 15 to avoid motion interference between the multiple scrubbing paddles 14. In this embodiment, three scrubbing paddles 14 are provided, and the diameter of the scrubbing paddle 14 located in the middle is larger than the diameter of the scrubbing paddles 14 located on both sides, so as to effectively clean the quartz sand that falls onto the baffle filter plate 15 while ensuring scrubbing effect and efficiency.
[0038] It is understood that the drain outlet 13 is equipped with a drain valve 18 to control the opening and closing of the drain outlet 13. Correspondingly, the discharge outlet 11 is equipped with a discharge valve 19 to control the opening and closing of the discharge outlet 11. In this embodiment, both the drain valve 18 and the discharge valve 19 are gate valves to ensure that both the drain outlet 13 and the discharge outlet 11 have sufficient material flow capacity. Of course, valves of other structural forms can also be used as the drain valve 18 and the discharge valve 19.
[0039] Combination Figure 2 and Figure 3 The inclined dewatering mechanism 30 includes a roller plate 31; the roller plate 31 is inclined from the scrubbing machine 10 toward the pickling tank 20, and the upper end of the roller plate 31 is located below the discharge port 11 and the lower end extends to the pickling tank 20; the roller plate 31 is arrayed with a plurality of filter holes 32 so that the quartz sand particles can roll on the inclined dewatering mechanism 30 and discharge the separated water.
[0040] Typically, baffles 34 are provided on both sides of the rolling plate 31 along its length to prevent the sides of the long rolling plate 31 from falling off when the quartz sand particles roll on it.
[0041] Based on this, the rolling plate 31 is provided with a plurality of arc-shaped protrusions 33 (the protrusion height is less than half the diameter of the quartz sand particles, such as 0.5 mm); the arc-shaped protrusions 33 are arranged along the width direction of the rolling plate 31, and the plurality of arc-shaped protrusions 33 are spaced apart along the length direction of the rolling plate 31, so that the quartz sand is forced to roll under the action of gravity through the blocking effect of the arc-shaped protrusions 33, so as to prevent the quartz sand particles from sliding relative to each other on the rolling plate 31 and thus failing to dehydrate quickly.
[0042] Recombined Figure 2 The inclined dewatering mechanism 30 also includes a deceleration plate 35. One side of the deceleration plate 35 is connected to the lower end of the rolling plate 31, and the other side is higher than the lower end of the rolling plate 31. The deceleration plate 35 is located above the pickling tank 20 so that the quartz sand particles rolling off the rolling plate 31 roll upward along the deceleration plate 35 before entering the pickling tank 20, thus avoiding excessive kinetic energy of the quartz sand and splashing of the pickling solution in the pickling tank 20.
[0043] It should be understood that the deceleration plate 35 and the rolling plate 31 are connected by an arc-shaped transition plate 36 to ensure that the quartz sand can roll from the rolling plate 31 to the deceleration plate 35, and to prevent the quartz sand from accumulating between the deceleration plate 35 and the rolling plate 31.
[0044] In summary, the washing device for cleaning quartz sand provided in this embodiment includes a scrubbing machine 10, an acid washing tank 20, and an inclined dewatering mechanism 30. The scrubbing machine 10 can scrub the coarse sand after screening, and the scrubbing machine is provided with a discharge port 11 to discharge the scrubbed quartz sand. The inclined dewatering mechanism 30 is located between the scrubbing machine 10 and the acid washing tank 20, and is inclined from the scrubbing machine 10 toward the acid washing tank 20, so as to receive the quartz sand output by the scrubbing machine 10.
[0045] In operation, first close the discharge valve 19 and drain valve 18, then feed the quartz sand to be cleaned into the cleaning cylinder 12, inject the pickling solution into the pickling tank 20, and inject clean water into the cleaning cylinder 12. Then, drive the scrubbing paddle to rotate, using the scrubbing paddle 14 to agitate the clean water and quartz sand within the cleaning cylinder 12 for scrubbing. The resulting muddy water settles in the sedimentation chamber 17, and the cleaned quartz sand is retained in the cleaning chamber 16 by the baffle filter plate 15. After cleaning, open the drain valve 18 and discharge valve 19. At this time, wastewater is discharged from the drain outlet 13, and the quartz sand rolls towards the discharge outlet 11 to be discharged, thus achieving rapid separation of wastewater and quartz sand.
[0046] The quartz sand discharged from the discharge port 11 falls onto the upper end of the roller groove formed by the roller plate and the baffle plate 34, and rolls down along the roller plate 31 into the pickling tank 20 for pickling. When the quartz sand rolls on the inclined dewatering mechanism 30, the quartz sand particles roll rapidly, causing the water attached to the quartz sand particles to detach from the quartz sand particles under the action of centrifugal force. This removes most of the water attached to the quartz sand before it is put into the pickling tank 20, thereby preventing the concentration of the acidic solution in the pickling tank 20 from decreasing rapidly and ensuring the pickling effect of the quartz sand.
[0047] In summary, the washing device for cleaning quartz sand provided in this embodiment can remove most of the water adhering to the quartz sand before it is put into the acid washing tank 20, thereby avoiding a rapid decrease in the concentration of the acid solution in the acid washing tank 20 and ensuring the acid washing effect of the quartz sand.
[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
