Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing equipment, in particular to energy-saving quartz sand processing equipment. Background Art

[0002] Quartz sand is an important industrial raw material, which is widely used in many fields due to its excellent physical and chemical properties. Quartz sand is one of the main raw materials for making glass. Its high purity and stable chemical properties make it an indispensable raw material in the glass industry. Quartz sand is used to make casting molds. Because of its high temperature resistance and good chemical stability, it can ensure the accuracy and quality of castings. It is used to produce cement, concrete, bricks and other building materials to improve the hardness and durability of these materials.

[0003] The existing Chinese patent with publication number CN108435400A discloses a quartz sand processing equipment, including a main seat body and a connecting part installed on the main seat body, a protrusion is fixedly provided on the top of the left end face of the main seat body, a first sliding groove is provided in the bottom end face of the protrusion, a first sliding block is slidably installed in the first sliding groove, a first opening is provided in the bottom end face of the first sliding block, a locking device is symmetrically provided in the inner walls on the left and right sides of the first opening, a first screw rod is threadedly installed in the first sliding block, the left extending end of the first screw rod is rotatably connected with the left inner wall of the first sliding groove, the right extending end of the first screw rod is dynamically connected with a first electric motor, the outer surface of the first electric motor is fixed in the left end face of the main seat body, a second opening is provided in the left end face of the main seat body under the protrusion, and the right inner wall of the second opening is connected to a transfer cavity

[0004] In the design of the above-mentioned quartz sand processing equipment, there are still the following problems:

[0005] 1. The shape and size of the crushing chamber have a great influence on the uniformity of the discharge. If the design of the crushing chamber is unreasonable, the force on the ore in the crushing chamber will be uneven, which may lead to inconsistent particle sizes after crushing. Moreover, as the use time increases, the jaw plate will gradually wear, resulting in poor crushing effect and uneven discharge particle size.

[0006] 2. The existing quartz sand crushing equipment has the problems of low crushing efficiency and high energy consumption when crushing large pieces of quartz ore, which will lead to serious energy waste in the crushing process, affecting production efficiency and cost; at the same time, there is a problem of particle size control accuracy: the crushed ore needs to be classified according to particle size, but the existing equipment cannot meet the high-precision requirements in particle size control, resulting in a wide range of product particle size distribution, affecting subsequent processing procedures and product quality.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] Please refer to Figure 1-Figure 8 , comprising: a first crushing mechanism 100, comprising a mounting frame 102, on which a first crushing assembly for crushing large pieces of quartz sand is fixedly provided, and a driving assembly for driving the first crushing assembly to perform jaw crushing is also provided on the mounting frame 102;

[0041] The third crushing mechanism 300 includes a lower material bin 301, which is fixedly arranged below the mounting frame 102. A lower material hopper 302 for lowering materials is provided at the upper port of the lower material bin 301. A screening plate 305 for screening quartz sand with a larger particle size after the first crushing is provided in the lower material bin 301. An anti-blocking component 303 for preventing the screening plate 305 from being blocked by quartz sand is provided on the lower material bin 301. A third crushing component for crushing small pieces of quartz sand screened off the screening plate 305 is also provided on the lower material bin 301.

[0042] The second crushing mechanism 200 includes a crushing bin 201 arranged on one side of a lower bin 301, and a discharge port and a feed port are respectively opened on one side of the lower bin 301 along the height direction from high to low, and a discharge pipe 203 and a feed pipe 204 are respectively provided on one side of the crushing bin 201. The other end of the discharge pipe 203 is connected to the lower bin 301 through the discharge port, and the other end of the feed pipe 204 is connected to the lower bin 301 through the feed port. A secondary crushing component 202 is provided in the crushing bin 201 for crushing large pieces of quartz sand screened out by the screening plate 305.

[0043] As can be seen from the above, the large pieces of quartz sand are first fed into the first crushing mechanism 100, and the first crushing component performs jaw crushing under the drive of the driving component. This crushing method performs preliminary crushing of the large pieces of quartz sand and reduces its volume through the relative movement of the two crushing surfaces. The quartz sand after preliminary crushing falls into the lower hopper 302 of the lower bin 301 by gravity. Inside the lower bin 301, the screening plate 305 screens the quartz sand. The quartz sand particles with larger particle sizes are blocked at the top by the screening plate 305, while the quartz sand particles with smaller particle sizes fall into the third crushing mechanism 300 below through the sieve holes of the screening plate 305 for further processing. In order to prevent the quartz sand on the screening plate 305 from being blocked, the anti-blocking component 303 will work periodically to ensure the smooth progress of the screening process. The large pieces of quartz sand blocked by the screening plate 305 enter the rolling bin 201 of the second crushing mechanism 200 through the feed port of the lower bin 301 and the feed pipe 204. When the large pieces of quartz sand enter the rolling bin 201, the rolling assembly 202 performs secondary crushing on the large pieces of quartz sand to further reduce its volume. The crushed quartz sand returns to the lower bin 301 through the discharge pipe 203 and the discharge port, and is further refined through the third crushing mechanism 300 together with the small pieces of quartz sand screened by the screening plate 305. The quartz sand processed by the third crushing mechanism 300 eventually reaches the required particle size standard and is then collected.

[0044] Embodiment 2

[0045] Please refer to Figure 1-Figure 8 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0046] As a further technical solution of this embodiment, the first crushing assembly includes a first jaw plate 103 fixed on a mounting frame 102, and the mounting frame 102 is also movably provided with a second jaw plate 106 for cooperating with the first jaw plate 103 to perform jaw crushing. A shock-absorbing member 107 is provided on one side of the second jaw plate 106, and the other end of the shock-absorbing member 107 is connected to a fixed block 108, and both ends of the fixed block 108 are connected to the inner wall of the mounting frame 102.

[0047] Furthermore, the driving assembly includes a first pulley 104 and an auxiliary wheel 105 symmetrically arranged on both sides of the mounting frame 102, and the two ends of the second jaw 106 are eccentrically connected to the first pulley 104 and the auxiliary wheel 105 through a rotating shaft. A motor 101 is also provided at the upper end of the mounting frame 102, and the driving end of the motor 101 is connected to the first pulley 104 through a belt drive.

[0048] Further, the second crushing assembly includes a rolling assembly 202 rotatably arranged in the rolling bin 201, the rolling assembly 202 includes a rotating shaft 2021 rotatably arranged on the center of one side of the rolling bin 201, a plurality of fixed frames 2022 are arranged on the circumference of the rotating shaft 2021, and the plurality of fixed frames 2022 are evenly distributed along the circumference of the center of the rotating shaft 2021, and a rolling cylinder 2023 is rotatably arranged at the non-fixed end of each of the fixed frames 2022, and a gap is left between the rolling cylinder 2023 and the inner wall of the rolling bin 201, and a sieve plate is arranged at the connection between the rolling bin 201 and the discharge pipe 203;

[0049] One end of the rotating shaft 2021 passes through the rolling bin 201 and a second pulley 205 is provided at the end of the rotating shaft 2021 passing through. The first pulley 104 is connected to the second pulley 205 through a belt transmission.

[0050] Furthermore, the anti-blocking component 303 includes a mounting plate 3031 fixed on the inner wall of the mounting frame 102, the center of the mounting plate 3031 is rotatably connected to a rotating plate 3032 through a rotating shaft 2021, positioning blocks 3033 are symmetrically arranged at both ends of the horizontal diameter of the mounting plate 3031, a clamping block is arranged on the rotating plate 3032, and a movable ring 3035 is arranged on one side of the rotating plate 3032 to slide in cooperation with the clamping block, and sliding rods 3034 are respectively arranged at both ends of the movable ring 3035, and the two sliding rods 3034 respectively penetrate and slidably connect the positioning blocks 3033 on both sides, one end of one of the sliding rods 3034 is provided with a push plate 3037, and one end of the other sliding rod 3034 is rotatably provided with a connecting rod 3036, and the other end of the connecting rod 3036 is provided with a push plate 3037;

[0051] One end of the rotating shaft 2021 passes through the side wall of the mounting plate 3031 and the mounting frame 102, and a third pulley 3030 is provided at one end of the rotating shaft 2021, and the second pulley 205 is connected to the third pulley 3030 through a belt transmission mechanism.

[0052] Furthermore, the third crushing assembly includes a plurality of rolling rollers 306 rotatably arranged at the bottom end of the mounting frame 102, the plurality of rolling rollers 306 are distributed side by side, and a sprocket wheel 304 is provided at one end of each rolling roller 306 passing through the mounting frame 102, the plurality of sprocket wheels 304 are connected by chain transmission, a fourth pulley is provided on any sprocket wheel 304, and the second pulley 205 is connected to the fourth pulley by belt transmission.

[0053] As can be seen from the above, when the motor 101 is started, its driving end drives the first pulley 104 to rotate through the belt transmission. Since the first pulley 104 is connected with the second pulley 205 and the fourth pulley through the belt transmission, the whole system starts to move in tandem.

[0054] When the first crushing assembly is working, the rotation of the first pulley 104 connects the second jaw 106 and the auxiliary wheel 105 through the eccentric rotation shaft, so that the second jaw 106 performs a reciprocating jaw crushing action. In this process, the first jaw 103 remains fixed, while the second jaw 106, under the constraints of the shock-absorbing member 107 and the fixed block 108, performs preliminary crushing of the material at a certain frequency and force. The shock-absorbing member 107 can absorb part of the impact and reduce noise and vibration. At this time, the quartz sand is crushed from the initial state into quartz sand of different sizes, and the crushed quartz sand falls into the lower hopper 302 into the lower hopper 301. At this time, the anti-blocking assembly on the screening plate 305 works, and the third pulley 3030 is driven by one end of the rotating shaft 2021 and is connected to the second pulley 205 through a belt transmission. When the second pulley 205 rotates, the third pulley 3030 also rotates synchronously, thereby driving the turntable 3032 to rotate on the mounting plate 3031. The block on the rotating disk 3032 cooperates with the movable sleeve 3035, so that the two slide bars 3034 slide in the positioning block 3033, thereby pushing the push plate 3037 to reciprocate. Prevent the material from being blocked in the first crushing assembly or the second crushing assembly, and ensure the continuity and smoothness of the crushing process. When the large pieces of quartz sand that are not screened by the screening plate 305 enter the second crushing assembly through the anti-blocking assembly, the second crushing assembly starts to work. At this time, the rotation of the first pulley 104 is transmitted to the second pulley 205 through the belt, thereby driving the rotating shaft 2021 to rotate in the rolling bin 201. The multiple fixed frames 2022 on the rotating shaft 2021 and the rolling cylinder 2023 thereon rotate accordingly, and further crush the preliminarily crushed materials. The rolling cylinder 2023 maintains a certain gap with the inner wall of the rolling bin 201 to ensure that the materials can be crushed evenly and effectively. The crushed materials enter the discharge pipe 203 through the screen plate for collection or further processing. When the small pieces of quartz sand processed by the second crushing assembly and the quartz sand screened by the screening plate 305 enter the third crushing assembly, similar to the second pulley 205, the fourth pulley is connected to the chain wheel 304 through a belt drive, thereby driving a plurality of parallelly distributed rolling rollers 306 to rotate. These rolling rollers 306 perform the final fine crushing on the materials that have passed the first two crushing processes to ensure that the materials meet the required particle size requirements.

[0055] Embodiment 3

[0056] Please refer to Figure 1-Figure 8 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0057] As a further technical solution of this embodiment, further, the aperture size of the sieve holes on the screening plate 305 is the same as the aperture size of the sieve holes on the sieve plate on the rolling bin 201. The teeth on the rolling cylinder 2023 are evenly distributed in an array, and the inner wall of the rolling bin 201 is provided with tooth grooves for meshing with the teeth of the rolling cylinder 2023. The larger particles of quartz sand after preliminary screening enter the rolling bin 201 through the feed port of the lower bin 301 and the feed pipe 204. In the rolling bin 201, the rotating shaft 2021 drives the multiple fixed frames 2022 and the rolling cylinder 2023 thereon to rotate. The teeth on the rolling cylinder 2023 are evenly distributed in an array, meshing with the tooth grooves on the inner wall of the rolling bin 201, and further crushing the material through mutual extrusion and shearing. The crushed material is screened again by the screen plate, and only the quartz sand that meets the smaller particle size requirements can pass through the screen plate into the discharge pipe 203 for collection or further processing.

[0058] Furthermore, the teeth on the rolling roller 306 are arranged in a spiral array, and two adjacent rolling rollers 306 mesh with each other. After being processed by the second crushing assembly, the still large quartz sand particles or the materials that are not completely crushed may fall into the third crushing assembly for processing. A plurality of rolling rollers 306 arranged side by side are connected by a chain transmission, and the teeth on each rolling roller 306 are arranged in a spiral array, and two adjacent rolling rollers 306 mesh with each other. When the rolling roller 306 rotates, the materials are finely crushed by the meshing and shearing action of the teeth until the required particle size requirements are reached.

[0059] Furthermore, the screening plate 305 is divided into an inclined portion and a straight portion, and one end of the inclined portion maintains an angle of 30 degrees with one side of the lower silo 301. Large pieces of quartz sand are first fed into the first crushing assembly for preliminary crushing. The motor 101 drives the first pulley 104 to rotate, and the second jaw plate 106 connected eccentrically and the first jaw plate 103 are used for jaw crushing to initially crush the large pieces of quartz sand into smaller particles. The crushed material falls into the lower silo 301 and is initially screened by the screening plate 305. The size of the sieve holes on the screening plate 305 is the same as the size of the sieve holes on the sieve plate on the subsequent rolling bin 201, ensuring that only quartz sand that meets certain particle size requirements can continue to flow downward. The screening plate 305 is divided into an inclined portion and a straight portion, and the design of the inclined portion helps the material to slide more smoothly into the screening area and reduce the risk of blockage.

[0060] As can be seen from the above, the large pieces of quartz sand are first crushed by the jaw crusher of the first crushing component to reduce the particle size, and then fall into the screening plate 305 of the lower hopper 301 for preliminary screening. The design of the screening plate 305 ensures that only quartz sand that meets the particle size requirements enters the rolling bin 201. In the rolling bin 201, multiple rolling cylinders 2023 with teeth are engaged with the inner wall tooth grooves, and the material is further crushed by rotation. The crushed material is screened again through the screen plate, and the quartz sand that meets the smaller particle size requirements enters the discharge pipe 203. For particles that still do not meet the standards, the spiral toothed rolling roller 306 in the third crushing component is finely crushed until the particle size requirements are met. During the whole process, the inclined design of the screening plate 305 and the anti-blocking component 303 promote the smooth flow of materials and reduce blockages.

[0061] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiments.
