Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing equipment, in particular to a sorting device for quartz sand production. Background Art

[0002] During the production and processing of quartz sand, the quartz stone needs to be crushed, scrubbed, washed, graded, dusted, dried, stored, bagged and other steps. During crushing, the quartz stone ore is initially crushed by the coarse crusher, and then the coarse material is conveyed by the belt conveyor to the fine crusher for further crushing. The finely crushed stone enters the vibrating screen to screen out two kinds of stone. The stone that meets the feed particle size of the sand making machine enters the sand making machine to make sand, and the other part of the return material enters the fine crusher for secondary fine crushing, so as to match the subsequent water quenching, flotation and other processes;

[0003] Authorized patent number CN115228548B discloses a sorting device for quartz sand production. The device can crush quartz sand by setting a crushing component in the main body of the device, crushing large pieces of quartz sand into medium-sized particles of quartz sand, and then selecting smaller particles of quartz sand through screening by the screening component and filtering by the filtering component. At the same time, the manually adjusted lifting component can control the crushing space of the crushing component, and the pre-treated quartz sand can be crushed again to obtain more quartz sand with smaller particles. This device can not only process quartz sand quickly, but also process quartz sand particles of different sizes very finely, thereby improving the efficiency of the quartz sand sorting device. However, when the device is actually used, it still has the following defects:

[0004] The above patent mainly uses a crushing component to crush large pieces of quartz sand into medium-sized particles of quartz sand for screening. However, when crushing quartz sand, it often requires multiple stages of crushing before screening, and the crushed particle size of quartz sand is prone to be too large in some places, which not only easily leads to blockage of the material after crushing, but also affects the subsequent screening accuracy. At the same time, it is necessary to collect and feed the excessive quartz sand for a second time and re-crush it, which greatly prolongs the processing flow of quartz sand and reduces the crushing accuracy and efficiency of quartz sand fine crushing. In addition, when screening quartz sand, it is often necessary to collect and transport quartz sand of different particle sizes, and quartz sand is easy to adhere to the inner wall of the conveying channel when feeding, and it is not easy to classify and discharge and transport quartz sand of different particle sizes, which increases the difficulty of material collection for staff and reduces the work efficiency of subsequent processing.

[0054] Embodiment 1, as Figure 1-3As shown, when the quartz sand is crushed by the crushing device 6, the driver 7 is started to drive the second rotating shaft 83 to rotate, and synchronously drive the belt transmission mechanism to make the second rotating shaft 83 and the first rotating shaft 82 rotate synchronously. At this time, the first rotating shaft 82 can drive the impeller 81 to rotate at the discharge port of the feed trough 61 to avoid blockage of the discharge port by excessive quartz sand, thereby promoting the discharge of quartz sand. The rotation of the second rotating shaft 83 drives the cam 84 to rotate and contact the inclined guide plate 87, so that the inclined guide plate 87 moves back and forth under the elastic guidance of the guide rod seat 85 and the spring 86, so that the quartz sand placed in the inclined guide plate 87 can be quickly introduced into the filter screen cylinder 910 for fine crushing, thereby increasing the structural discharge guidance and improving the working efficiency of quartz sand crushing and guiding.

[0055] Embodiment 2, as Figure 1-3 and Figure 7-8 As shown in the figure, when the quartz sand particles are screened into three kinds of particles through the first oblique screening groove 34, the second oblique screening groove 35 and the movable rod 36 and placed into the channels inside the three groups of annular guide grooves 22, the motor base 24 can be started to drive the rotating plate 23 to rotate continuously, so that the rotating plate 23 drives the three groups of scrapers 21 to move in the channels of the annular guide grooves 22, so as to scrape and transport the quartz sand particles to the three discharge ports 29 in different directions for discharge. At this time, a conveyor belt can be set under the device so as to separate the three groups of conveyor belts to discharge the three kinds of screened quartz sand particles. The sand particles are received and transported so as to quickly carry out subsequent processing operations, and the rotation of the rotating plate 23 can drive the three groups of rotating rods 27 and the toothed disc 26 to engage with the fixed toothed disc 25 structure, prompting one group of toothed discs 26 to rotate along the meshing position around the fixed toothed disc 25, and at the same time, the three groups of toothed discs 26 drive the rotating rods 27 and the scraper plate 28 to rotate to scrape and brush the inner wall of the annular guide trough 22. This structure not only scrapes off the quartz sand adhering to the wall of the annular guide trough 22, but also greatly improves the cleaning effect of the inner side of the annular guide trough 22 during subsequent cleaning operations by using the scraper structure.

[0056] Working principle: In the sorting device for quartz sand production;

[0057] When sorting quartz sand, firstly, the quartz sand to be sorted is placed in the crushing device 6, and the input quartz sand is preliminarily crushed with the cooperation of the feed trough 61 and the double-roll crushing device 62, so that the quartz sand can enter the filter screen cylinder 910 through the guide of the inclined guide plate 87 after being crushed. At this time, the rotating rod 95 can be driven to rotate by starting the driving motor 91, so that the rotating rod 95 drives the bevel gear set 94 to mesh, and the sleeve 96 drives the filter screen cylinder 910 to centrifugally rotate under the guidance of the guide block 98 and the annular guide groove 97, and the outer gear ring 93 is synchronously driven to mesh with the gear 92 structure with the rotation of the filter screen cylinder 910, so as to promote The filter screen cylinder 910 and the brush stick 912 are rotated downward so that the filter screen cylinder 910 can filter the quartz sand and scrape and clean it with the brush stick 912 at the same time, so as to maintain the filtering effect of the filter screen cylinder 910. As the filter screen cylinder 910 rotates, the crushing mechanism 911 is started to cause the quartz sand entering the filter screen cylinder 910 to be thrown upward under the action of centrifugal rotation and then fall into the crushing part of the crushing mechanism 911, so that the quartz sand that cannot be filtered is repeatedly crushed under the cooperation of the filter screen cylinder 910 and the crushing mechanism 911, so that the processing technology of the fine crushing structure can be used to screen the quartz sand within the specified force range, thereby improving the screening accuracy and the qualified rate;

[0058] After the quartz sand is filtered through the filter cylinder 910 and the particle size is within the specified range, it can directly fall into the screening bin 31. During this period, as the rotating rod 95 rotates, the gear set 33 structure can be synchronously driven to engage, causing the crankshaft 38 to rotate and drive the three sets of movable rods 36 to synchronously pull the first oblique screening slot 34, the second oblique screening slot 35 and the oblique material guide slot 37 to reciprocate under the limit guidance of the guide rail 32, so that the quartz sand particles falling into the first oblique screening slot 34 are screened once and fall into the inner side of the second oblique screening slot 35 for secondary screening. Finally, the quartz sand particles falling from the second oblique screening slot 35 are regarded as the minimized particle size.
