Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand washing, and particularly relates to a quartz sand washing system. Background Art

[0002] As an important industrial raw material, quartz sand has a wide range of applications in multiple industries, including but not limited to construction, glass manufacturing, chemical industry, and water treatment. To ensure that the quality of quartz sand meets the requirements of different industries, it is usually necessary to clean and classify it to remove dirt, dust, and other impurities adhering to the surface. This process is usually completed by a dedicated quartz sand washing system process.

[0003] The entire quartz sand washing system process mainly consists of several key parts: a feeding device, a cleaning device, a grading device, and the collection of the final product; among them, a common feeding device is a conveyor belt. The conveyor belt is the primary component for feeding the raw quartz sand into the cleaning system. Since the raw quartz sand usually contains a large amount of soil, dust, and other debris, these substances will adhere to the conveyor belt during the conveying process and gradually accumulate over time, thus affecting the conveying efficiency and the overall performance of the machine. To solve this problem, a scraper is usually used to remove the debris on the conveyor belt. During the operation of the conveyor belt, the fixed-mounted scraper contacts the conveyor belt, and the debris adhering to it is scraped off by the pressure of the scraper. Although this method can solve the problem of debris accumulation to a certain extent, it also has some obvious deficiencies. Due to the continuous friction between the scraper and the conveyor belt, long-term operation will cause the conveyor belt to wear more severely, shortening its service life. At the same time, frequently replacing the worn conveyor belt will increase the equipment maintenance cost. If the scraper is improperly assembled or severely worn, it may also be unable to effectively remove all the debris, thus affecting the subsequent cleaning effect.

[0004] Therefore, in combination with the above problems, a quartz sand washing system that can effectively clean the conveyor belt and reduce the wear of the conveyor belt is proposed. Summary of the Utility Model

Detailed implementation manners

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] Embodiment: A quartz sand washing system, as Figures 1-4As shown in the figure, it includes an installation bracket 1, a sand supply conveyor 2, a sand washing frame 3, a drain pipe 31, a rotating frame 4, a driving motor 5, a sand collection frame 6, a flushing spray pipe 7, a discharge frame 8, a sand discharge conveyor 9, a surplus material collection frame 10, an electric push rod 11, a sliding frame 12, a slider 13 and an electric roller brush 14. On the installation bracket 1, a sand supply conveyor 2 for transporting quartz sand for feeding is inclined. The sand supply conveyor 2 is in a state of being lower on the left and higher on the right, and forms an inclined channel for impurities to slide down in cooperation with the surplus material collection frame 10 adapted to its inclination angle. On the right side of the installation bracket 1, there is a sand washing frame 3 for connecting the discharge part of the sand supply conveyor 2. At the front of the sand washing frame 3, a drain pipe 31 is fixedly arranged. The drain pipe 31 is located at the upper side position of the sand washing frame 3, which can limit the water level inside the sand washing frame 3 to ensure a certain water level for cleaning the quartz sand. Inside the sand washing frame 3, a rotating frame 4 is rotatably arranged. At the front of the sand washing frame 3, a driving motor 5 is fixedly installed. The output shaft of the driving motor 5 is connected to the rotating shaft of the rotating frame 4, which can provide power for the rotation of the rotating frame 4, thereby promoting the overall sand washing operation. On the outer surface of the rotating frame 4, two circles of sand collection frames 6 for collecting quartz sand are circumferentially arranged. A plurality of sand collection frames 6 are arranged in a circumferential direction for each circle. The two circles of sand collection frames 6 are arranged in a staggered manner, and each sand collection frame 6 in the same circle is in a close contact state. Moreover, the side of the sand collection frame 6 suitable for shoveling quartz sand is an inclined surface. This adjacent and closely connected state can facilitate the feeding of quartz sand through the inclined surface. Arranged holes for filtering are opened on both the upper and lower sides of the sand collection frame 6. The arranged holes can further separate the quartz sand and impurities to a certain extent, and at the same time, the quartz sand can be blocked to drain the water. On the left side of the sand washing frame 3, there is a flushing spray pipe 7. The spray port of the flushing spray pipe 7 is inclined to the right, which is convenient for injecting the water column into the sand collection frame 6 to clean the quartz sand for the second time. On the right side of the sand washing frame 3, a discharge frame 8 for discharging the washed quartz sand is inclined. The right end of the discharge frame 8 is connected to a sand discharge conveyor 9 for transporting the discharged quartz sand; at the bottom of the sand supply conveyor 2, there is a surplus material collection frame 10. In the middle position at the bottom of the surplus material collection frame 10, an electric push rod 11 is fixedly arranged. The telescopic end of the electric push rod 11 is connected to a sliding frame 12. At the top of the sliding rods at the left and right ends of the sliding frame 12, sliders 13 are arranged. The sliders 13 pass through the surplus material collection frame 10 and form a sliding fit with it. An electric roller brush 14 is arranged between the two sliders 13. The electric roller brush 14 contacts the sand supply conveyor 2 to scrape off impurities. By controlling the electric roller brush 14 with the electric push rod 11, the effect of controlling the scraping operation can be achieved, and the situation of unnecessary loss caused by uncontrollable contact time can be avoided.

[0022] As Figure 5 shown, it further includes a vibration motor 15. A vibration motor 15 for jittering the discharge of quartz sand is arranged on the discharge frame 8. The setting of the vibration motor 15 enables the quartz sand accumulated due to excessive moisture to be discharged more quickly.

[0023] As shown Figure 5 in the figure, it further includes an installation frame 16 and a dryer 17. An installation frame 16 is provided on the top of the sand discharge conveyor 9, and a dryer 17 is fixedly installed on the top of the installation frame 16. The dryer 17 can dry the wet quartz sand.

[0024] When the sand washing process of quartz sand is required, first, the staff ensures that the whole device is placed on a flat ground, and then the quartz sand to be cleaned is put on the sand supply conveyor 2. With the transportation of the sand supply conveyor 2, when the impurities and quartz sand reach the end, they will fall into the sand washing frame 3. During this process, since the impurities and quartz sand are in a mixed state, some impurities will adhere to the surface of the sand supply conveyor 2 during transportation. Then, the electric push rod 11 is started, and the sliding frame 12 is driven by the electric push rod 11 to move upward, driving the slider 13 to move upward on the surplus material collection frame 10, and then driving the electric roller brush 14 to contact the surface of the sand supply conveyor 2. Then, the electric roller brush 14 is started, and the attached impurities are scraped off by the continuous rolling of the electric roller brush 14. The fallen impurities will fall along the inclined surface of the surplus material collection frame 10. By controlling the contact between the electric roller brush 14 and the sand supply conveyor 2 by the electric push rod 11, the distance and time between the two can be more effectively controlled, thus avoiding the situation that the electric roller brush 14 is affected by long-term contact; then the transported quartz sand and impurities will enter the sand washing frame 3. At the same time, the flushing nozzle 7 fills water into the inside, and the drain pipe 31 controls the water level inside the sand washing frame 3. Then, the driving motor 5 is started, and the driving motor 5 drives the rotating frame 4 to rotate clockwise, so that the sand collecting frame 6 rotates circumferentially and continuously shovels the quartz sand at the bottom. When it rotates to the flushing nozzle 7, it will be flushed again. Then, along with the rotation of the rotating frame 4, the sand collecting frame 6 will cooperate with the inclined surface of the former and fall into the discharge frame 8. Then, the vibration motor 15 vibrates the discharge frame 8 to speed up the discharging operation of the quartz sand by shaking. When the quartz sand falls onto the sand discharge conveyor 9, it will finally be dried by the dryer 17. In summary, the overall operation process is completed.

[0025] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
