In addition, the embodiments of the present invention provide examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0035] The present invention aims to solve the shortcomings existing in the background technology and provides a quartz rod raw material crushing and screening device and a use method. Through the setting of the transmission component, the crushed raw material can be transported to the screening plate for screening processing as soon as possible, thereby reducing the process flow and improving production efficiency. At the same time, it can avoid blockage of the discharge pipe and shaking of the screening plate, thereby increasing the screening speed of the screening plate.

[0036] The embodiment of the present invention provides a quartz rod raw material crushing and screening device and a method for using the same. The quartz rod raw material crushing and screening device and the method for using the same are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example 1 See also Figure 1-Figure 16 In this embodiment, a quartz rod raw material crushing and screening device is provided, including: a box body 1, a device block 2 is installed inside the box body 1, a conveying block 3 is installed on one side of the device block 2, three screening plates 7 are rotatably connected to the box body 1 through bearings, a dust removal box 8 is installed on the top of the box body 1, two crushing rollers 103 are rotatably connected to the box body 1 through bearings, and a grinding disc 205 is provided inside the box body 1; a transmission component arranged inside the conveying block 3 is used to transport the crushed material and drive the screening plate 7 to vibrate; and an adjustment component arranged inside the screening plate 7 is used to adjust the screening aperture of the screening plate 7.

[0039] Among them, through the setting of the transmission component, the crushed raw material can be transported to the screening plate 7 for screening processing as soon as possible, thereby reducing the process flow and improving production efficiency. At the same time, through the setting of the extrusion wheel 603 and the extrusion belt 307, the raw material at the bottom of the discharge pipe 303 can be brought to the outlet of the discharge pipe 303 to avoid blockage of the discharge pipe 303, and can drive the screening plate 7 to shake, thereby increasing the screening speed of the screening plate 7 and avoiding the accumulation of raw materials on the screening plate 7, resulting in blockage of the screening holes 702. Secondly, through the setting of the adjustment component, the screening aperture of the screening plate 7 can be quickly adjusted according to the required quartz powder particle size, thereby improving the adaptability of the device.

[0040] Example 2 On the basis of Example 1, a feed pipe 101 is connected to the top of the box body 1, two drive motors 102 are installed on one side of the box body 1, two crushing rollers 103 are respectively connected to the two drive motors 102, a plurality of evenly arranged crushing blocks 104 are connected to the crushing rollers 103, and the crushing blocks 104 on the two crushing rollers 103 are staggered, a crushing groove 201 is opened on the top of the equipment block 2, a fixing plate 202 is installed inside the crushing groove 201, and a fixing plate 202 is installed at the bottom of the fixing plate 202. A rotating motor 204 is installed, which is rotatably connected to a grinding disc 205. The axis of the grinding disc 205 is staggered with the transmission shaft on the rotating motor 204. A plurality of evenly distributed protrusions 206 are connected to the surface of the grinding disc 205. A plurality of evenly distributed crushing blocks 207 are connected to the inner wall of the crushing groove 201. Two discharge holes 203 are provided on the fixed plate 202. A plurality of rollers 208 are installed at the bottom of the grinding disc 205, and a brush 209 is connected to one side of the roller 208.

[0041] During the production process of the quartz rod, the raw material needs to be crushed to form small particles for the convenience of the subsequent production process. At this time, the raw material can be poured into the box body 1 through the feed pipe 101, and at the same time, the two crushing rollers 103 are driven to rotate by two driving motors 102, and the two crushing rollers 103 rotate in opposite directions. At this time, the raw material is initially crushed by the multiple crushing blocks 104 on the crushing rollers 103, and the crushed raw material falls into the grinding trough 201 and slides along the grinding disc 205 to between the grinding disc 205 and the grinding trough 201. At this time, the raw material is crushed by the multiple crushing blocks 104 on the grinding rollers 103. The rotating motor 204 drives the grinding disc 205 to rotate, so that the grinding disc 205 grinds the crushed raw materials through a plurality of protrusions 206 and crushing blocks 207 to form smaller particles for later processing. During the rotation of the grinding disc 205, due to the eccentric setting of the grinding disc 205, the space between the peripheral side of the grinding disc 205 and the crushing groove 201 will continue to increase and decrease. On the one hand, when the space increases, the larger raw materials above can fall downward, and on the other hand, when the space decreases, the raw materials can be squeezed and crushed, thereby further improving the grinding efficiency. Then, during the rotation of the grinding disc 205, the setting of multiple rollers 208 can share the weight of the grinding disc 205 and allow the grinding disc 205 to rotate smoothly. At the same time, the rotation of the rollers 208 drives the brush 209 to rotate, sweeping the raw materials remaining on the fixed plate 202 after grinding to the discharge hole 203, and discharged through the discharge hole 203. The discharged raw materials can be discharged into the conveying pipe 302 through the conduit 301.

[0042] Then, an exhaust fan 801 is installed inside the dust removal box 8, a detachable filter 802 is installed inside the dust removal box 8, a first exhaust pipe 803 is connected to one side of the dust removal box 8, and one end of the first exhaust pipe 803 extends above the grinding disc 205, and a second exhaust pipe 804 is connected to the bottom of the dust removal box 8, and the second exhaust pipe 804 is located above the screening plate 7.

[0043] A large amount of dust will be generated in the process of crushing, grinding and screening the raw materials. At this time, the gas in the dust removal box 8 is extracted to the outside through the exhaust fan 801, so that the air pressure inside the dust removal box 8 drops, and the gas inside the box body 1 enters the dust removal box 8 through the first exhaust pipe 803 and the second exhaust pipe 804, and the dust particles in the gas are filtered through the filter net 802 to avoid a large amount of floating particles or dust from being directly discharged, causing pollution to the working environment.

[0044] Example 3 On the basis of Example 1, the transmission assembly includes: a cavity opened inside the conveying block 3, in which a servo motor 304 is installed; a conveying pipe 302 opened inside the conveying block 3, a discharge pipe 303 is connected to one side of the top of the conveying pipe 302, and a guide tube 301 is connected to the other side of the bottom of the conveying pipe 302; a first rotating rod 4 rotatably connected to the inside of the cavity through a bearing, and a second rotating rod 403, a third rotating rod 404 and a driving rod 405 are rotatably connected to the inside of the cavity through bearings, and the second rotating rod 403, the third rotating rod 404 and the driving rod 405 are arranged from top to bottom; a cam 5 connected to the second rotating rod 403, the third rotating rod 404 and the driving rod 405; a movable plate 706 connected to one side of the screening plate 7, and one end of the movable plate 706 extends into the cavity and is located above the cam 5.

[0045] After the raw materials enter the conveying pipe 302, the servo motor 304 drives the auger 305 to rotate, so that the auger 305 conveys the materials in the conveying pipe 302 to the discharge pipe 303, and discharges the materials to the top screening plate 7 through the discharge pipe 303. The raw materials are screened by the multiple screening plates 7, and the screened raw materials slide along the surface of the screening plate 7 into the collection frame 9. On the basis of Example 3, further, the top drive of the servo motor 304 is connected to an auger 305, and the auger 305 is located in the conveying pipe 302, a crawler is provided between the auger 305 and the first rotating rod 4, the first rotating rod 4 is connected to a driving wheel 401, the second rotating rod 403 is connected to a driven wheel 402 which meshes oppositely with the driving wheel 401, the second rotating rod 403 is connected to a rotating wheel 4031, the third rotating rod 404 is connected to a transmission wheel 4041, the driving rod 405 is connected to a driving wheel 4051, the rotating wheel 4031, the transmission wheel 4041 and the driving wheel 4051 are all connected by a chain, a plurality of mounting plates 707 are connected to one side of the conveying block 3, and a plurality of return springs 708 are connected between the mounting plate 707 and the screening plate 7.

[0046] During the rotation of the auger 305, the first rotating rod 4 is driven to rotate by the crawler, and at this time, the first rotating rod 4 drives the second rotating rod 403 to rotate through the driving wheel 401 and the driven wheel 402, and then because the rotating wheel 4031 on the second rotating rod 403 is connected with the transmission wheel 4041 on the third rotating rod 404 and the driving wheel 4051 on the driving rod 405 through a chain, when the second rotating rod 403 rotates, the third rotating rod 404 and the driving rod 405 are driven by the rotating wheel 4031, the transmission wheel 4041 and the driving wheel 4051 405 rotates synchronously, so that the cam 5 on the third rotating rod 404 and the driving rod 405 rotates, and because the movable plate 706 at one end of the screening plate 7 is located above the cam 5 and is in close contact with the surface of the cam 5, during the rotation of the cam 5, the protruding part of the cam 5 is constantly in contact with the movable plate 706, thereby driving the movable plate 706 and one end of the screening plate 7 to continuously rise and fall, realizing the continuous shaking of the screening plate 7, accelerating the screening efficiency of the screening plate 7 for the raw materials, and then through the setting of the reset spring 708, the movable plate 706 can always be in close contact with the surface of the cam 5.

[0047] Example 4 On the basis of Example 1 and Example 3, further, an extrusion chamber 306 communicating with the discharge pipe 303 is opened inside the conveying block 3, an extrusion belt 307 is connected inside the extrusion chamber 306, three second rotating rods 602 are rotatably connected to the extrusion chamber 306 through bearings, the three second rotating rods 602 are connected by tracks, each of the second rotating rods 602 is connected to an extrusion wheel 603, and the protruding parts of the extrusion wheels 603 on the three second rotating rods 602 face different directions, a first rotating rod 6 is rotatably connected to the cavity through a bearing, a transmission belt is provided between the first rotating rod 6 and the second rotating rod 602, a rotating gear 601 is connected to one end of the first rotating rod 6, a driving gear 4052 meshing with the rotating gear 601 is connected to the driving rod 405, and the rotating gear 601 and the driving gear 4052 are both bevel gears.

[0048] Then, during the rotation of the driving rod 405, the driving rod 405 drives the driving gear 4052 to rotate, and the driving gear 4052 drives the first rotating rod 6 to rotate through the rotating gear 601, and the first rotating rod 6 drives the second rotating rod 602 to rotate through the transmission belt. Then, since the three second rotating rods 602 are connected by tracks, the three second rotating rods 602 rotate synchronously. At this time, the extrusion wheels 603 on the three second rotating rods 602 squeeze the extrusion belt 307, so that the extrusion belt 307 protrudes at one end close to the conveying pipe 302, and the protruding part moves toward the screening plate 7, so that the extrusion belt 307 drives the raw material in the discharge pipe 303 to be conveyed, further ensuring that the raw material passes through the discharge pipe 303 quickly and avoids blockage of the discharge pipe 303.

[0049] Example 5 On the basis of Example 1, the adjustment component includes: a plurality of screening holes 702 opened on the screening plate 7, and the plurality of screening holes 702 are evenly arranged and distributed; a screening slot 701 opened inside the screening plate 7, and the screening slot 701 is communicated with the plurality of screening holes 702; an adjustment plate 703 slidably connected to the inside of the screening slot 701, and a plurality of adjustment holes 704 are opened on the adjustment plate 703, and the number and position of the adjustment holes 704 correspond to the number and position of the plurality of screening holes 702; two threaded holes opened on one side of the screening plate 7, a threaded rod 705 is threadedly connected inside the threaded hole, one end of the threaded rod 705 is connected to the adjustment plate 703 through a bearing, and a scale is provided on the threaded rod 705, a plurality of collecting frames 9 are provided inside the box body 1, and the plurality of screening plates 7 are inclined toward the direction of the collecting frame 9.

[0050] Then, when screening the raw materials, the screening aperture of the screening plate 7 can be adjusted according to the production of different types of quartz rods, so that raw materials suitable for different types of quartz rods can be screened out. When adjusting the screening aperture of the screening plate 7, the threaded rod 705 can be rotated. At this time, the threaded rod 705 drives the adjustment plate 703 to move under the action of the threaded hole, so that the adjustment plate 703 slides in the screening groove 701. At this time, the overlapping space between the adjustment hole 704 on the adjustment plate 703 and the screening hole 702 changes, thereby realizing the adjustment of the screening aperture of the screening plate 7.
