DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] This embodiment is a technical improvement made to address the technical problem that the existing quartz raw material crushing and screening machine cannot simultaneously reduce dust during the process of crushing and screening the quartz raw materials, resulting in a poor environment around the crushing and screening machine and causing harm to the health of the operators.

[0027] See also Figure 1 and Figure 2 In this embodiment, a quartz raw material crushing and screening machine provided in this embodiment includes a driving mechanism 1, a crushing and screening mechanism 2 and a spray dust removal mechanism 3. The crushing and screening mechanism 2 and the spray dust removal mechanism 3 are both connected to the driving mechanism 1. The driving mechanism 1 drives the crushing and screening mechanism 2 and the spray dust removal mechanism 3 to move synchronously. The crushing and screening mechanism 2 is used for crushing and screening the quartz raw materials, and the spray dust removal mechanism 3 is used for spraying and dust reduction during the crushing and screening process.

[0028] During specific use, the driving mechanism 1 drives the crushing and screening mechanism 2 to crush and screen the quartz raw material, while driving the spray dust removal mechanism 3 to perform a spray dust removal action.

[0029] Specifically, see Figure 2 and Figure 3 In this embodiment, the spray dust removal mechanism 3 includes a water storage cylinder 4 and a sliding piston 5. The water storage cylinder 4 is connected to an atomizing nozzle 6, which is used for spraying and dust reduction. The water storage cylinder 4 is connected to an automatic water supply pipe 7, which is connected to an external water source and is used to add water to the water storage cylinder 4. The sliding piston 5 is slidably arranged in the water storage cylinder 4. The sliding piston 5 is connected to the driving mechanism 1. The sliding piston 5 adjusts the pressure in the water storage cylinder 4 by sliding in the water storage cylinder 4. The atomizing nozzle 6 sprays and reduces dust according to the pressure change. The automatic water supply pipe 7 is provided with an automatic water supply mechanism 8. The automatic water supply mechanism 8 is closed or opened as the pressure in the water storage cylinder 4 changes. When the automatic water supply mechanism 8 is turned on, water is supplied to the water storage cylinder 4. The sliding piston 5 moves inward to reduce the volume of the water storage cylinder 4 and sprays water under pressure. The sliding piston 5 moves outward to increase the volume of the water storage cylinder 4 and the automatic water supply pipe 7 supplies water.

[0030] When in use, the driving mechanism 1 drives the sliding piston 5 to slide inside the water storage cylinder 4, thereby controlling the volume inside the water storage cylinder 4. The change in the volume inside the water storage cylinder 4 drives the change in the pressure inside the water storage cylinder 4: See also Figure 3 The spray dust removal mechanism 3 on the right side, when the internal volume of the water storage cylinder 4 decreases, that is, the pressure increases, the water inside the water storage cylinder 4 is pressurized and sprayed out from the atomizing nozzle 6 to spray and reduce dust. At the same time, the automatic water replenishment mechanism 8 is automatically closed under pressure, and the water replenishment to the inside of the water storage cylinder 4 stops at this time; See also Figure 3 The spray dust removal mechanism 3 on the left side, when the internal volume of the water storage cylinder 4 increases, that is, the pressure decreases, the automatic water replenishment mechanism 8 automatically opens, at this time, the automatic water replenishment pipe 7 automatically replenishes water into the water storage cylinder 4, and the spray dust reduction action at the atomizing nozzle 6 is temporarily stopped; By repeating the above-mentioned actions, synchronous spraying and dust reduction can be achieved during the crushing and screening process of the quartz raw materials.

[0031] Specifically, see Figure 3 and Figure 4 In this embodiment, the automatic water replenishment mechanism 8 includes a water replenishment shell 9 and a sealing plate 10. The water replenishment shell 9 is fixedly arranged on the automatic water replenishment pipe 7. A water inlet through hole 11 and a water outlet through hole 12 are opened on the water replenishment shell 9. A sealing spring 13 is fixedly arranged in the water replenishment shell 9. The sealing plate 10 is connected to the sealing spring 13, and the sealing plate 10 is slidably arranged in the water replenishment shell 9. The sealing plate 10 is used to block or open the water inlet through hole 11. The diameter of the sealing plate 10 is larger than the diameter of the water inlet through hole 11, so that the water inlet through hole 11 can be completely blocked, and the diameter of the sealing plate 10 is smaller than the diameter of the water replenishment shell 9, ensuring that the water flow has sufficient flowing water replenishment space.

[0032] When in use, in the initial state, the water replenishment housing 9 is connected to the automatic water replenishment pipe 7 through the water inlet through hole 11 and the water outlet through hole 12, and water is replenished into the water storage cylinder 4 through the connecting channel; when the sliding piston 5 moves inward along the water storage cylinder 4, the water storage space inside the water storage cylinder 4 is reduced, and the internal pressure of the water storage cylinder 4 is increased, and the sealing plate 10 is exerted with a force close to the water inlet through hole 11 through the pressure, at this time, the sealing spring 13 is extended, and the sealing plate 10 blocks the water inlet through hole 11, stops water injection, and the water in the water storage cylinder 4 is sprayed out through the atomizing nozzle 6 under the pushing action of the sliding piston 5, so as to realize spray dust reduction; It is worth noting that if the circular cross-sections of the water inlet through hole 11, the water outlet through hole 12, the inner cavity of the water replenishment shell 9, and the sealing plate 10 in this embodiment are replaced with other common shapes, they also fall within the protection scope of this solution.

[0033] Specifically, see Figure 8 In this embodiment, the driving mechanism 1 includes a driving motor 14, a transmission shaft 15 and a driving assembly. The crushing and screening mechanism 2 is fixedly arranged on the output shaft of the driving motor 14. The driving motor 14 is used to drive the crushing and screening mechanism 2 to crush and screen the quartz raw material. A set of first pulleys are fixedly arranged on the transmission shaft 15 and the output shaft of the driving motor 14. A set of first driving belts 16 are sleeved on the two sets of first pulleys.

[0034] Specifically, see Figure 8 In this embodiment, the driving assembly also includes a guide plate 40, which is fixed on the crushing and screening mechanism 2, and the sliding push rod 26 is slidably set on the guide plate 40. The lifting and lowering of the sliding push rod 26 is guided and limited by the setting of the guide plate 40, which can further improve the stability of the lifting and sliding of the sliding push rod 26.

[0035] During specific use, when the driving disk 19 is driven to rotate, the driving column is driven to rotate with it. The driving column slides along the driving groove 25 and drives the driving member 20 to move up and down. The driving member 20 drives the sliding piston 5 to slide in the water storage cylinder 4 through the sliding push rod 26. The pressure in the water storage cylinder 4 is regulated by controlling the sliding piston 5.

[0036] It is worth noting that, in the present solution, the belt connection drive method is only a specific embodiment, and a transmission structure such as a gear transmission may also be used as an alternative structure.

[0037] Specifically, see Figure 1 , Figure 2 and Figure 3 In this embodiment, two groups of driving components are symmetrically arranged on the outside of the crushing and screening mechanism 2, and two groups of spray dust removal mechanisms 3 are correspondingly arranged in the driving components, and the two groups of driving components drive the corresponding spray dust removal mechanisms 3 in turn to spray dust removal.

[0038] Specifically, the driving slide posts 24 of the two groups of driving components are arranged at an angle of 180° on their respective driving disks 19. When one group of driving slide posts 24 rotates to the bottom with its driving disk 19, the other group of driving slide posts 24 rotates to the top with its driving disk 19. At this time, when one group of driving components drives its corresponding spray dust removal mechanism 3 to perform a spraying action, the other group of driving components drives its corresponding spray dust removal mechanism 3 to perform a water intake and replenishment action, thereby ensuring that the spray dust removal mechanism 3 is always in working condition.

[0039] Specifically, see Figure 3 and Figure 6 In this embodiment, the crushing and screening mechanism 2 includes a shell 27, a crushing disc 28 and a grinding roller 29.

The crushing disc 28 and the grinding roller 29 are both fixedly provided on the output shaft of the driving motor 14 and rotatably provided in the shell 27. The crushing disc 28 is located above the grinding roller 29. Under the cooperation of the crushing disc 28 and the grinding roller 29, the input quartz raw material is knocked, crushed and ground in turn to ensure the sufficient crushing degree of the quartz raw material.

[0040] Specifically, see Figure 3 and Figure 6 In this embodiment, multiple groups of crushing discs 28 are fixedly provided along the output shaft of the driving motor 14, and the diameter of the crushing discs 28 arranged from top to bottom gradually increases, thereby realizing step-by-step crushing of the quartz. The grinding roller 29 is a truncated cone structure, and the distance between the grinding roller 29 and the inner wall of the shell 27 gradually decreases from top to bottom. The distance between the grinding roller 29 and the inner wall of the shell 27 is smaller than the distance between the crushing disc 28 and the inner wall of the shell 27, thereby grinding the crushed quartz.

A scraper 35 is fixedly provided on the outer side of the guide pipe 33, and the scraper 35 slides in contact with the guide pipe 33. It is arranged on the inner bottom wall of the shell 27, and the quartz after crushing and grinding is screened under the action of the screening net 32. The quartz particles that meet the use size are screened by the screening net 32 ​​and fall onto the bottom wall of the shell 27, and the quartz particles that do not meet the use size are discharged through the guide pipe 33 to be crushed again, and the guide pipe 33 drives the scraper 35 to rotate when it rotates. Under the action of the scraper 35, the quartz particles that meet the use size after screening are scraped to the discharge pipe 31 for discharge; the screening net 32 ​​is a funnel-shaped structure, which can further improve the screening efficiency.

The bottom wall of the material guide shell 37 is inclined. The height of the end of the material guide shell 37 close to the discharge port 38 is lower than the height of the end away from the discharge port 38. Through the setting of the material guide shell 37, the discharge position can be led outward from the bottom of the shell body 27 to facilitate the operation of the discharge position point.

[0043] Specifically, see Figure 1 and Figure 2 A conveyor belt 39 is provided below the discharge pipe 31 and the discharge port 38. The conveyor belt 39 can be used to output or transport the screened quartz raw material to the next process.

[0044] Specifically, see Figure 1 and Figure 2 A plurality of atomizing nozzles 6 are connected to the water storage cylinder 4, and atomizing nozzles 6 are correspondingly arranged at the positions of the feeding hopper 30, the discharge pipe 31 and the discharge port 38, so as to better realize the spraying and dust reduction at the above-mentioned positions.

[0045] The working principle of a quartz raw material crushing and screening machine provided in this embodiment is as follows: 1. Add the quartz raw material from the feeding hopper 30 into the housing 27, start the driving motor 14, and the driving motor 14 drives the crushing wheel 28 and the grinding roller 29 to rotate, thereby crushing and grinding the quartz raw material in turn. The crushed and ground quartz raw material is screened through the screening net 32; The quartz particles meeting the use size are screened by the screening net 32 ​​and fall onto the bottom wall of the housing 27. The scraper 35 is driven by the guide pipe 33 to rotate, and the screened quartz particles meeting the use size are scraped to the discharge pipe 31 for discharge. The quartz particles that do not meet the use size are guided to the guide shell 37 through the guide tube 33, and are discharged through the discharge port 38 of the guide shell 37 to be crushed again; 2. The driving motor 14 drives the crushing wheel disc 28 and the grinding roller 29 to crush and grind the quartz raw material, and drives the transmission shaft 15 to rotate through the action of the first driving belt 16. Under the action of the second driving belt 21, the transmission shaft 15 drives the driving shaft 17 to rotate. Through the meshing of the driving conical wheel 22 and the driven conical wheel 23, the driving shaft 17 drives the driven shaft 18 to rotate, and the driven shaft 18 drives the driving disc 19 to rotate. The driving disc 19 drives the driving slide column 24 fixed thereon to rotate, and the driving slide column 24 slides in the driving slide groove 25 to apply force to the driving member 20, and the driving member 20 drives the sliding piston 5 to slide in the water storage cylinder 4 through the sliding push rod 26; Specifically, when the sliding push rod 26 is driven upward by the driving member 20 to drive the sliding piston 5 to move into the water storage cylinder 4, the internal volume of the water storage cylinder 4 becomes smaller, the internal pressure of the water storage cylinder 4 increases, and the water inside the water storage cylinder 4 is sprayed out from the atomizing nozzle 6 under pressure to perform a spraying and dust reduction action; at the same time, the sealing plate 10 is moved toward the water inlet through hole 11 under the action of the pushing pressure, the sealing spring 13 is stretched, and the sealing plate 10 blocks the water inlet through hole 11 to stop water injection; When the sliding push rod 26 is driven down by the driving member 20 and drives the sliding piston 5 to move outward along the inside of the water storage cylinder 4, the internal volume of the water storage cylinder 4 increases and the internal pressure of the water storage cylinder 4 decreases. At this time, no water is sprayed out from the atomizing nozzle 6, and the pressure applied to the sealing plate 10 is removed, the sealing spring 13 is reset, the sealing plate 10 is moved away from the water inlet hole 11, and the automatic water replenishment pipe 7 is in a unobstructed state, and water is replenished into the water storage cylinder 4, waiting for the next squeezing spray.

[0046] The above actions are repeated in a cycle, thereby spraying and reducing the dust generated during the crushing and screening process.
