Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, specifically to an adjustable coarse and fine particle separation device for quartz sand processing. Background Technology

[0002] Quartz sand is widely used in many industrial fields such as glass manufacturing, casting, ceramics, and refractory materials. These applications have strict requirements on the particle size of quartz sand. In glass manufacturing, different particle sizes of quartz sand affect properties such as transparency and strength. With continuous industrial development, the demand for quartz sand is increasing daily, prompting quartz sand processing enterprises to improve production efficiency and product quality to meet market demands.

[0003] The utility model patent application with publication number "CN221908174U" discloses a coarse and fine particle separation device for quartz sand processing, including a conveying cylinder and a support. A screen is installed at the lower end of the conveying cylinder, and a spiral conveying rod is rotatably installed inside the conveying cylinder. The outer wall of the spiral conveying rod is provided with uniformly distributed scrapers for scraping the conveyed quartz sand. A motor is installed on the outer wall of the conveying cylinder to drive the spiral conveying rod. A receiving hopper is installed on the support and is located at the lower end of the screen. The motor drives the spiral conveying rod to rotate inside the conveying cylinder to convey quartz sand of different particle sizes. When conveyed to the screen, the smaller particle size quartz sand falls into the receiving hopper through the screen. During the conveying process, the quartz sand is agitated by the scrapers and slides down the inclined surface of the scrapers. The smaller particle size quartz sand is screened out through the screen, increasing the screening efficiency.

[0004] The aforementioned document discloses a primary particle separation device for quartz sand processing, which has the following defects: the screening device lacks an effective adjustment mechanism for the feed flow rate. Under different production conditions, such as when different production orders have different requirements for the amount of quartz sand to be processed, the screening device with a fixed feed flow rate is difficult to adjust flexibly. If it is necessary to control the feed flow rate, it may require manual intervention or adjustment of the power of other equipment, which may lead to low production efficiency and relatively low flexibility of use.

[0005] Therefore, it can be seen that the existing coarse and fine particle separation device for quartz sand processing does not have a structure that can adjust the feed flow rate. It is necessary to improve the existing shortcomings and provide an adjustable coarse and fine particle separation device for quartz sand processing. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable primary separation device for coarse and fine particles in quartz sand processing, which solves the problem that existing screening devices lack an effective adjustment mechanism for feed flow rate, making it difficult to flexibly adjust the feed flow rate under different production conditions.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an adjustable coarse and fine particle separation device for quartz sand processing, comprising a feeding cylinder, a first screening plate fixedly installed on the inner wall of the feeding cylinder, two sets of support frames fixedly installed on the outer surface of the feeding cylinder, a discharge pipe fixedly installed on the outer surface of one end of the feeding cylinder, a feeding hopper fixedly installed on the outer surface of the end of the feeding cylinder away from the discharge pipe, a motor fixedly installed on one end of the feeding cylinder, an auger conveying rod rotatably connected to the inner wall of the feeding cylinder, one end of the auger conveying rod being connected to the output end of the motor, a fine material guide box fixedly installed between the two sets of support frames, the fine material guide box being located below the first screening plate, an adjustment mechanism installed inside the feeding hopper, the adjustment mechanism comprising an electric push rod and a first connecting shell, an electric push rod fixedly installed on one side of the feeding hopper, the output end of the electric push rod extending into the interior of the feeding hopper, and the first connecting shell fixedly installed at the output end of the electric push rod.

[0009] Furthermore, the adjustment mechanism also includes a guide plate and a second connecting shell. The guide plate is rotatably connected to the inner wall of the feed hopper, and the second connecting shell is fixedly installed on one side of the guide plate.

[0010] Furthermore, the adjustment mechanism also includes a rotating connecting plate, and the second connecting shell and the first connecting shell are rotatably connected by the rotating connecting plate.

[0011] Furthermore, a second screening plate is fixedly installed on the inner wall of the inclined surface inside the fine material guide box.

[0012] Furthermore, a vibration motor is fixedly installed on one side of the fine material guide box.

[0013] Furthermore, a guide pipe is fixedly installed on the outer surface of the fine material guide box, and the guide pipe is installed below the second screening plate.

[0014] This utility model has the following beneficial effects:

[0015] (1) The present invention can adjust the flow rate of quartz sand into the conveying cylinder through the adjustment mechanism in the feeding hopper. The electric push rod extends and retracts, and drives the guide plate to rotate through the first connecting shell, the rotating connecting plate and the second connecting shell. The rotation of the guide plate changes the size of the inlet of the feeding hopper, thereby changing the flow rate of quartz sand in the feeding hopper, adapting to different production conditions and improving the flexibility of use.

[0016] (2) The present invention allows the quartz sand to fall into the fine material guide box below through the first screening plate. The inner wall of the inclined surface of the fine material guide box is equipped with a second screening plate. When the vibration motor on one side of the fine material guide box is started, it generates vibration, which causes the quartz sand in the fine material guide box to move on the inclined second screening plate under vibration. The finer quartz sand particles will pass through the second screening plate and then be discharged through the guide pipe, while the relatively coarser fine particles that do not pass through the second screening plate will remain in the fine material guide box and be discharged from the outlet of the fine material guide box. Through the first screening plate in the conveying cylinder and the second screening plate in the fine material guide box, the coarse and fine particles of quartz sand can be effectively distinguished, which improves the accuracy and efficiency of screening.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this utility model is an adjustable coarse and fine particle separation device for quartz sand processing, including a feeding cylinder 1, a first screening plate 101 fixedly installed on the inner wall of the feeding cylinder 1, two sets of support frames 2 fixedly installed on the outer surface of the feeding cylinder 1, a discharge pipe 3 fixedly installed on the outer surface of one end of the feeding cylinder 1, a feeding hopper 4 fixedly installed on the outer surface of the end of the feeding cylinder 1 away from the discharge pipe 3, a motor 5 fixedly installed on one end of the feeding cylinder 1, an auger conveying rod 6 rotatably connected to the inner wall of the feeding cylinder 1, one end of the auger conveying rod 6 being connected to the output end of the motor 5, a fine material guide box 8 fixedly installed between the two sets of support frames 2, the fine material guide box 8 being located below the first screening plate 101, and an adjustment mechanism 7 installed inside the feeding hopper 4;

[0027] Quartz sand enters the conveying cylinder 1 from the feed hopper 4. The motor 5 starts and drives the auger conveyor 6 to rotate. The auger conveyor 6 conveys the quartz sand from the feed hopper 4 into the conveying cylinder 1 towards the discharge pipe 3. Inside the conveying cylinder 1, the first screening plate 101 on the inner wall performs preliminary screening of the quartz sand. Larger particles of quartz sand cannot pass through the first screening plate 101 and will continue to move towards the discharge pipe 3 as the auger conveyor 6 rotates, and will eventually be discharged from the discharge pipe 3, becoming the coarse particles.

[0028] The adjustment mechanism 7 includes an electric push rod 701 and a first connecting shell 702. An electric push rod 701 is fixedly installed on one side of the feed hopper 4. The output end of the electric push rod 701 extends into the interior of the feed hopper 4. The output end of the electric push rod 701 is fixedly installed with the first connecting shell 702.

[0029] The adjustment mechanism 7 also includes a guide plate 703 and a second connecting shell 704. The guide plate 703 is rotatably connected to the inner wall of the feed hopper 4, and the second connecting shell 704 is fixedly installed on one side of the guide plate 703.

[0030] The adjusting mechanism 7 also includes a rotating connecting plate 705, and the rotating connecting plate 705 is rotatably connected between the second connecting shell 704 and the first connecting shell 702;

[0031] The adjusting mechanism 7 in the feed hopper 4 can adjust the flow rate of quartz sand entering the conveying cylinder 1. The electric push rod 701 extends and retracts, and drives the guide plate 703 to rotate through the first connecting shell 702, the rotating connecting plate 705 and the second connecting shell 704. The rotation of the guide plate 703 changes the size of the inlet of the feed hopper 4, thereby changing the flow rate of quartz sand in the feed hopper 4, adapting to different production conditions and improving the flexibility of use.

[0032] A second screening plate 9 is fixedly installed on the inner wall of the inclined surface inside the fine material guide box 8;

[0033] A vibration motor 10 is fixedly installed on one side of the fine material guide box 8;

[0034] A guide pipe 11 is fixedly installed on the outer surface of the fine material guide box 8, and the guide pipe 11 is installed below the second screening plate 9;

[0035] Smaller particles of quartz sand fall through the first screening plate 101 into the fine material guide box 8 below. A second screening plate 9 is installed on the inner wall of the inclined surface inside the fine material guide box 8. The vibration motor 10 on one side of the fine material guide box 8 is started, generating vibration, which causes the quartz sand in the fine material guide box 8 to move on the inclined second screening plate 9 under vibration. Finer quartz sand particles will pass through the second screening plate 9 and then be discharged through the guide pipe 11, while relatively coarser fine particles that do not pass through the second screening plate 9 remain in the fine material guide box 8 and are discharged from the outlet of the fine material guide box 8. Through two screenings, the coarse and fine particles of quartz sand can be effectively distinguished by the first screening plate 101 in the conveying cylinder 1 and the second screening plate 9 in the fine material guide box 8, improving the accuracy and efficiency of screening.

[0036] In use, firstly, quartz sand enters the conveying cylinder 1 from the feed hopper 4. The motor 5 starts and drives the auger conveyor rod 6 to rotate. The auger conveyor rod 6 conveys the quartz sand from the feed hopper 4 into the conveying cylinder 1 towards the discharge pipe 3. Inside the conveying cylinder 1, the first screening plate 101 on the inner wall performs preliminary screening of the quartz sand. Larger particles of quartz sand cannot pass through the first screening plate 101 and will continue to move towards the discharge pipe 3 as the auger conveyor rod 6 rotates, eventually being discharged from the discharge pipe 3 as the coarse particles.

[0037] Smaller particles of quartz sand fall through the first screening plate 101 into the fine material guide box 8 below. A second screening plate 9 is installed on the inner wall of the inclined surface inside the fine material guide box 8. The vibration motor 10 on one side of the fine material guide box 8 is started to generate vibration, which causes the quartz sand in the fine material guide box 8 to move on the inclined second screening plate 9 under vibration. The finer quartz sand particles will pass through the second screening plate 9 and then be discharged through the guide pipe 11, while the relatively coarser fine particles that do not pass through the second screening plate 9 remain in the fine material guide box 8 and are discharged from the outlet of the fine material guide box 8. The coarse and fine particles of quartz sand can be effectively distinguished by the two screenings: the first screening plate 101 in the conveying cylinder 1 and the second screening plate 9 in the fine material guide box 8, which improves the accuracy and efficiency of screening.

[0038] The adjusting mechanism 7 in the feed hopper 4 can adjust the flow rate of quartz sand entering the conveying cylinder 1. The electric push rod 701 extends and retracts, driving the guide plate 703 to rotate through the first connecting shell 702, the rotating connecting plate 705, and the second connecting shell 704. The rotation of the guide plate 703 changes the inlet diameter of the feed hopper 4, thereby changing the flow rate of quartz sand in the feed hopper 4, adapting to different production conditions, and improving the flexibility of use.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
