Description

Technical Field

[0001] This utility model relates to the technical field of quartz raw material filtration equipment, specifically a rapid grading and screening device for water-washed and purified quartz sand. Background Technology

[0002] With the rapid development of modern science and technology, higher purity requirements have been placed on quartz, a basic raw material. Therefore, grading and screening devices are required when screening quartz sand.

[0003] Most existing screening devices lack an effective drying structure. Before screening quartz sand, it needs to be washed to improve its purity. After washing, the quartz sand is then screened. If the screening device lacks an effective drying structure, the quartz sand may stick together, affecting the screening effect and efficiency. Furthermore, damp quartz sand may adhere to the inner wall of the screening frame, leading to waste and also impacting the screening process.

[0004] Compared with the patent application number CN222766720U, this utility model discloses a rapid grading and screening device for washed and purified quartz sand, including a screening box and a sieve plate. This utility model adopts a push pin, a first sieve hole, a second sieve hole, and a third sieve hole. When grading and screening washed and purified quartz sand, the washed and purified quartz sand can be put into the screening box from the feed inlet. The washed and purified quartz sand slides down along the sieve plate. The electric cylinder pushes the lifting plate to move up and down, which in turn drives the push pin to move up and down. The push pin inserts into the first sieve hole, the second sieve hole, and the third sieve hole, pushing out the blocked washed and purified quartz sand from the first sieve hole, the second sieve hole, and the third sieve hole, thus improving the convenience of use and work efficiency.

[0005] The above solution can effectively clean the sieve holes, but it still does not have an effective drying structure.

[0006] Based on this, a rapid classification and screening device for water-washed and purified quartz sand is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-7 As shown, a rapid grading and screening device for water washing and purification of quartz sand includes a screening box 1, a closed door 2 hinged to the front surface of the screening box 1, multiple movable frames 5 inside the screening box 1, screening frames 6 inside each of the multiple movable frames 5, a feeding frame 4 installed on the right side of the upper surface of the screening box 1, and a collection frame 3 at the bottom of the inside of the screening box 1.

[0036] The screening component is located on the upper left side of the screening box 1 and is used to screen the quartz sand.

[0037] The drying assembly is located at the top inside the screening box 1 and is used to dry the damp quartz sand.

[0038] The dispersing component is located inside the feed frame 4 and is used to disperse and mix the quartz sand.

[0039] In this embodiment, when quartz sand needs to be graded and screened, the screening component starts to operate. At this time, the screening component will drive the moving frame 5 and the screening frame 6 to move back and forth. During the operation of the screening component, the drying component will also start to operate simultaneously. Then, quartz sand is added into the inside of the feed frame 4. When the quartz sand enters the inside of the feed frame 4, the dispersing component starts to operate. At this time, the dispersing component can effectively disperse and stir the quartz sand. During the operation of the dispersing component, the drying component can effectively dry the quartz sand, thereby avoiding the quartz sand from clumping. After the quartz sand is dried, it will naturally fall into the inside of the screening frame 6. At this time, the quartz sand can be graded and screened through multiple screening frames 6 (the sieve hole diameter inside the multiple screening frames 6 decreases from top to bottom). The quartz sand will be divided into large, medium and small sizes and collected in different screening frames 6. The smallest quartz sand will fall into the inside of the collection frame 3 for collection, which effectively improves the overall practicality of the device.

[0040] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the screening assembly includes a first motor 7 fixedly connected to the left side of the upper surface of the screening box 1. The output shaft of the first motor 7 is fixedly connected to a rotating rod 8 via a coupling. A support plate 19 is fixedly connected to the inner left side wall of the screening box 1. The other end of the rotating rod 8 is rotatably connected to the upper surface of the support plate 19. Multiple cams 21 are fixedly connected to the outside of the rotating rod 8. A movable groove for the cams 21 to move is opened on the left side surface of the screening box 1. Multiple telescopic rods 22 are fixedly connected to the inner right side wall of the screening box 1. The telescopic ends of every two telescopic rods 22 are fixedly connected to the right side surface of multiple moving frames 5. A connecting plate 20 is fixedly connected to the left side surface of each of the multiple moving frames 5. A sliding groove for the cams 21 to move is opened on the left side surface of each of the multiple connecting plates 20. A return spring is sleeved on the outside of each of the multiple telescopic rods 22. Spring 23, and multiple return springs 23, all abut against the moving frame 5 and the screening box 1. When the quartz sand needs to be screened, the first motor 7 starts to run. At this time, the first motor 7 will drive the rotating rod 8 to rotate synchronously. The rotating rod 8 will then drive the cam 21 to rotate synchronously. During the rotation of the cam 21, it will squeeze the connecting plate 20. The connecting plate 20 will then drive the moving frame 5 to move synchronously. The moving frame 5 will then squeeze the telescopic rod 22 and the return springs 23 synchronously. When the cam 21 continues to rotate, the return springs 23 will reset, thereby driving the moving frame 5 to reset synchronously. This cycle repeats, which can effectively move the moving frame 5 and the screening frame 6 back and forth, thereby effectively screening the quartz sand through the screening frame 6.

[0041] In one embodiment, such as Figures 1-3As shown, each of the multiple telescopic rods 22 is fitted with a bellows cover 24. The two ends of the bellows cover 24 are fixedly connected to the opposite side of the moving frame 5 and the screening box 1, respectively. By setting the bellows cover 24, the telescopic rods 22 and the return spring 23 can be effectively protected from dust and water, thereby effectively extending the service life of the telescopic rods 22 and the return spring 23, without affecting the normal use of the telescopic rods 22 and the return spring 23.

[0042] In one embodiment, such as Figures 1-3 As shown, multiple guide rods 9 are fixedly connected inside the screening box 1, and guide plates 10 are slidably connected to the outside of each guide rod 9. The opposite sides of each pair of guide plates 10 are fixedly connected to the front and rear surfaces of multiple moving frames 5, respectively. During the movement of the moving frames 5, the guide plates 10 will also move synchronously outside the guide rods 9. At this time, the guide plates 10 and guide rods 9 can effectively play a limiting and guiding role, thereby effectively improving the stability of the moving frames 5 and screening frames 6 during the movement, and thus effectively improving the screening efficiency and effect of quartz sand.

[0043] In one embodiment, such as Figure 3 and Figure 7 As shown, the drying assembly includes a connecting rod 25 rotatably connected to the top of the inside of the screening box 1. A rotating rod 8 and the connecting rod 25 are connected by a synchronous belt 27 and a pulley 28. An inlet fan 26 is fixedly connected to the bottom of the connecting rod 25. Ventilation holes are provided on the upper surface of the screening box 1. A heating cylinder 13 is fitted around the outside of the inlet fan 26. The outside of the heating cylinder 13 is fixedly connected to the top of the inside of the screening box 1. An electric heating tube 14 is fixedly installed on the inner wall of the heating cylinder 13. The bottom of the heating cylinder 13 is connected to the left side surface of the feed frame 4 via a connecting frame 15. During the rotation of the rotating rod 8, the heating cylinder 25 is connected by a synchronous belt 27 and a pulley 28. The stepping belt 27 and pulley 28 drive the connecting rod 25 to rotate synchronously. The connecting rod 25 then drives the inlet fan 26 to rotate synchronously. During the rotation of the inlet fan 26, the electric heating tube 14 starts to operate. At this time, the inlet fan 26 blows gas into the interior of the heating cylinder 13. When the gas enters the interior of the heating cylinder 13, the electric heating tube 14 heats the gas. The heated gas then enters the interior of the feed frame 4 through the connecting frame 15. At this time, the quartz sand can be effectively dried, thereby avoiding the quartz sand from clumping and further improving the screening efficiency and effect of the quartz sand.

[0044] In one embodiment, such as Figure 4As shown, the dispersing component includes a stirring rod 17 located inside the feed frame 4. A second motor 16 is fixedly connected to the front surface of the feed frame 4. The output shaft of the second motor 16 is fixedly connected to one end of the stirring rod 17 via a coupling. The other end of the stirring rod 17 is rotatably connected to the rear inner wall of the feed frame 4. Dispersing rods 18 are provided at equal intervals on the outer wall of the stirring rod 17. When it is necessary to disperse and stir the quartz sand, the second motor 16 starts to run. At this time, the second motor 16 will drive the stirring rod 17 to rotate synchronously. The stirring rod 17 will then drive the dispersing rods 18 to rotate synchronously. At this time, the quartz sand can be effectively stirred and dispersed by the dispersing rods 18, thereby further improving the drying efficiency and effect of the drying component on the quartz sand.

[0045] In one embodiment, such as Figures 1-3 As shown, an installation sleeve 11 is fixedly connected to the left side of the upper surface of the screening box 1. The installation sleeve 11 is equipped with a dustproof mesh cover 12. By setting the dustproof mesh cover 12, impurities in the external environment can be effectively prevented from being drawn into the feed frame 4 by the fan 26, thereby effectively improving the purity of the quartz sand.

[0046] In one embodiment, such as Figure 3 and Figure 7 As shown, the outer wall of the mounting sleeve 11 is symmetrically provided with fixing sleeves 29. Inside the fixing sleeves 29 is a fixing rod 30. One end of the fixing rod 30 is fixedly connected to a pull plate. An abutment plate 31 is fixedly connected to the outside of the fixing rod 30. An abutment spring 32 is sleeved on the outside of the fixing rod 30, abutting between the abutment plate 31 and the fixing sleeve 29. Guide grooves for the movement of the fixing rod 30 are provided on the contact surfaces of the fixing sleeve 29 and the mounting sleeve 11. The outer wall of the dustproof mesh cover 12 has slots for the movement of the fixing rod 30. When the dustproof mesh cover 12 needs to be fixed, simply pull the pull plate, which will then move the fixing... The rod 30 moves synchronously, and the fixed rod 30 then drives the contact plate 31 to move synchronously. During the movement of the contact plate 31, the contact spring 32 is squeezed. At this time, the dust cover 12 is inserted into the inside of the mounting sleeve 11, and then the pull plate is released. At this time, the contact spring 32 returns to its original position, driving the contact plate 31 and the fixed rod 30 to move synchronously. When the fixed rod 30 is inserted into the slot on the outer wall of the dust cover 12, the dust cover 12 and the mounting sleeve 11 can be fixed. At this time, the dust cover 12 can be fixed and installed, and it is convenient for the staff to disassemble, replace and clean the dust cover 12.

[0047] The above embodiment discloses a rapid grading and screening device for water-washed and purified quartz sand. When grading and screening of quartz sand is required, the first motor 7 starts operating. At this time, the first motor 7 drives the rotating rod 8 and the cam 21 to rotate synchronously. The cam 21 then drives the moving frame 5 and the screening frame 6 to move back and forth. During the rotation of the rotating rod 8, the connecting rod 25 also starts rotating synchronously, which in turn drives the inlet fan 26 to rotate synchronously. Quartz sand is then added into the feed frame 4. When the quartz sand enters the feed frame 4, the second motor 16 starts operating. At this time, the second motor 16 drives the stirring rod 17 and the dispersing rod 18 to rotate synchronously, thereby enabling the dispersing rod 18 to disperse the quartz sand. The quartz sand is dispersed and stirred. During the dispersion and stirring process, the electric heating tube 14 also starts to operate simultaneously. At this time, the electric heating tube 14 heats the air drawn in by the fan 26 and then transmits it to the inside of the feed frame 4. This effectively dries the quartz sand, thus preventing it from clumping. After the quartz sand is dried, it will naturally fall into the inside of the screening frame 6. At this time, the quartz sand can be graded and screened by multiple screening frames 6 (the sieve aperture inside the multiple screening frames 6 decreases from top to bottom). The quartz sand will be divided into large, medium and small sizes and collected in different screening frames 6. The smallest quartz sand will fall into the inside of the collection frame 3 for collection, which effectively improves the overall practicality of the device.

[0048] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
