Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand production technology, and in particular to a multi-stage crushing and grading equipment for quartz sand. Background Technology
[0002] Quartz sand, as an important industrial raw material, has wide applications in glass manufacturing, ceramics production, building materials, and the electronics industry. In existing technologies, to improve the utilization rate and product purity of quartz sand, it is usually necessary to crush it. To ensure that the crushing meets requirements, the crushed quartz sand also needs to be screened and graded. Those that fail to meet the crushing standards require secondary crushing. However, most existing quartz sand crushing and screening devices are static screens, which easily lead to the accumulation and blockage of quartz sand on the screen surface, affecting the screening accuracy and consequently the crushing quality and efficiency.
[0003] Quartz sand, as an indispensable industrial raw material, is widely used in many key fields such as glass manufacturing, ceramic production, building materials, and the electronics industry. To improve the utilization rate and purity of quartz sand, current technologies generally employ crushing followed by screening and grading to ensure effective crushing. However, most current quartz sand crushing and screening devices rely on static screening technology. In this process, quartz sand easily accumulates on the screen surface and clogs the screen holes, affecting not only the screening accuracy but also directly restricting the crushing quality and overall crushing efficiency. To obtain the required particle size distribution, substandard quartz sand must undergo tedious multiple crushing processes, which undoubtedly increases production costs and time consumption.

[0020] Reference Figure 1-2 A multi-stage crushing and grading device for quartz sand includes a frame 1, which serves as the supporting structure for the entire device, ensuring the stable installation and operation of each component. At least two crushing and grading mechanisms for crushing quartz sand are installed on the frame 1, serving as the core part of the device. Each crushing and grading mechanism includes a vertically installed crushing box 2 and a horizontally arranged screening cylinder 7 for crushing and grading quartz sand. Preferably, there are 2-4 crushing and grading mechanisms to facilitate adjustment according to actual needs and meet the requirements of different quartz sand scales and processing capacities.
[0021] A feed hopper 3 is installed at the top of the crushing box 2 to facilitate the input of quartz sand. A crushing roller 4 is installed inside the crushing box 2. Specifically, there are two crushing rollers 4, and a crushing gap is left between the two crushing rollers 4 for crushing the quartz sand. A discharge pipe 6 is installed at the bottom of the crushing box 2 to facilitate the output of the crushed quartz sand.
[0022] The screening cylinder 7 is rotatably mounted on the frame 1. A screening hole 12 is provided in the middle of the screening cylinder 7 for classifying the crushed quartz sand. In order to achieve the cooperation between the screening cylinder 7 and the crushing box 2, one end of the screening cylinder 7 is set as the feed end, and the other end of the discharge pipe 6 extends into the interior of the feed end of the screening cylinder 7, and the discharge pipe 6 does not contact the screening cylinder 7 to avoid affecting the rotation of the screening cylinder 7. The other end of the screening cylinder 7 is set as the discharge end, which ensures that the crushed quartz sand can smoothly enter the screening cylinder 7 for classification. In two adjacent crushing and classification mechanisms, the discharge end of the screening cylinder 7 of the previous crushing and classification mechanism is set directly above the feed hopper 3 of the crushing box 2 of the next crushing and classification mechanism to achieve the continuity of multi-stage crushing and classification.
[0023] In order to collect the graded quartz sand, a collection cylinder 8 is also fitted on the outside of the screening cylinder 7. In order to achieve uniform distribution and collection of quartz sand, the collection cylinder 8 is rotatably mounted on the frame 1. Preferably, the rotation direction of the screening cylinder 7 is opposite to the rotation direction of the collection cylinder 8. In order to facilitate the collection of graded quartz sand, a collection trough 11 is provided directly below the end of the collection cylinder 8 on the discharge end side of each screening cylinder 7.
[0024] In actual use, both the dividing cylinder and the collecting cylinder 8 are set at an angle, and the end of the screening cylinder 7 with a higher height is set as the feed end. This design helps the material flow smoothly and classify the material. Preferably, the dividing cylinder and the collecting cylinder 8 have the same tilt direction and tilt angle, which ensures the stability and coordination of the equipment.
[0025] A drive device I5 for driving the crushing roller 4 to rotate is installed on the crushing box 2. A drive device II9 for driving the screening cylinder 7 to rotate and a drive device III10 for driving the collecting cylinder 8 to rotate are installed on the frame 1. Preferably, the drive devices I5, II9, and III10 are all geared motors. A drive wheel is installed on the motor shaft of each geared motor. Transmission wheels that cooperate with the drive wheels are fitted on the support shaft of the crushing roller 4, the screening cylinder 7, and the collecting cylinder 8, so as to facilitate rotation under the drive of the geared motor.
[0026] The specific working process for this application is as follows:
[0027] Quartz sand raw material is fed into crushing box 2 through feed hopper 3;
[0028] Inside the crushing box 2, there is an appropriate crushing gap between the two crushing rollers 4. The crushing rollers 4 are driven to rotate by the drive device I5 (reduction motor) to perform preliminary crushing of the quartz sand.
[0029] The rotation speed and spacing of the crushing roller 4 can be adjusted according to the hardness and particle size of the quartz sand to achieve the best crushing effect.
[0030] The initially crushed quartz sand enters the screening cylinder 7 through the discharge pipe 6 at the bottom of the crushing box 2;
[0031] The screening cylinder 7 rotates under the drive of the drive device II9 (reduction motor) and classifies the quartz sand using the screening holes 12;
[0032] Qualified particles (i.e., quartz sand with the required particle size) fall into the collection cylinder 8 through the sieve hole 12;
[0033] The unqualified particles processed by the first crushing and grading mechanism enter the crushing box 2 of the next crushing and grading mechanism through the discharge end of the screening cylinder 7 for secondary crushing.
[0034] The same process is repeated in the subsequent crushing and grading mechanism until all the quartz sand meets the required particle size.
[0035] At the discharge end of each screening cylinder 7, qualified particles will fall into the corresponding collection cylinder 8;
[0036] The collecting cylinder 8 rotates under the drive of the drive device III10 (gear motor) to ensure that the particles are evenly distributed and eventually fall into the collecting tank 11;
[0037] Operators can periodically remove the graded quartz sand from collection tank 11 for further processing or packaging.
[0038] During operation, operators should wear appropriate protective equipment, such as dust masks and earplugs.
[0039] Maintenance and adjustment work must not be performed while the equipment is running to avoid accidents.
[0040] The equipment should be installed in a well-ventilated, dry environment free of corrosive gases to ensure its normal operation and service life.
[0041] In summary, the multi-stage crushing and grading equipment for quartz sand provided in this application can achieve efficient and precise grading of quartz sand through multi-stage crushing and screening. At the same time, through reasonable equipment maintenance and safe operation measures, the stable operation and long service life of the equipment can be ensured.
