[0002] Quartz sand is an important industrial raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemicals, plastics, rubber, abrasives and other industries. In these applications, the particle size requirements of quartz sand vary, so it is necessary to crush and grind to achieve the required particle size range.
[0003] At present, in the process of grinding quartz sand, the conventional practice is to put the quartz sand into the silo and use the high-speed rotating grinding disc and grinding balls to crush the quartz sand. However, the problem is that after the grinding is completed, the discharge of the powder lacks a particle size control mechanism, resulting in a wide distribution of the particle size of the discharged powder, which is difficult to accurately adjust. In this case, the discharged powder often contains particles with larger particle sizes, making it difficult to ensure the overall fineness of the powder, which will have an adverse effect on the subsequent processing technology and reduce the accuracy of the finished product.

DETAILED DESCRIPTION
[0026] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.
[0027] A quartz sand processing crushing and grinding device, such as Figure 1-Figure 4 As shown, it includes a mounting seat 1, a processing chamber 2, an air guide cylinder 3, a discharge frame 4, a driving motor 5, a rotating shaft 6, an isolation plate 7, an air intake ring 71, a feeding mechanism, a crushing mechanism and an air injection pipe 9. The mounting seat 1 is connected to the processing chamber 2, the air guide cylinder 3 is connected to the middle of the top of the processing chamber 2, the discharge frame 4 is connected to the left side of the air guide cylinder 3, the driving motor 5 is installed on the top of the air guide cylinder 3, the rotating shaft 6 is connected to the output shaft of the driving motor 5, the lower part of the processing chamber 2 is connected to the air intake ring 71, the isolation plate 7 is rotatably connected in the air intake ring 71, the rotating shaft 6 is connected to the isolation plate 7, a plurality of air injection holes are evenly spaced along the circumferential direction on the air intake ring 71, the processing chamber 2 is connected to the air injection pipe 9, the space between the isolation plate 7 and the processing chamber 2 constitutes an air injection chamber 21, the air injection pipe 9 is located below the isolation plate 7 and is connected to the air injection chamber 21, and a feeding mechanism for adding quartz sand and a crushing mechanism for crushing quartz sand are provided on the processing chamber 2.
[0028] like Figure 3 As shown, the feeding mechanism includes a feeding pipe 31, a spiral feeding shaft 32, a servo motor 33 and a lower hopper 34. The upper right side of the processing bin 2 is connected to the feeding pipe 31, the upper right side of the feeding pipe 31 is connected to the lower hopper 34, a servo motor 33 is installed on the right side of the feeding pipe 31, and the output shaft of the servo motor 33 is connected to the spiral feeding shaft 32.
[0029] like Figure 2 and Figure 4 As shown, the crushing mechanism includes a partition 81, a material strip 82, an extrusion frame 83, a rolling wheel 84 and an elastic member 85. The partition 81 is connected to the upper part of the processing chamber 2, and the feed pipe 31 passes through the partition 81. The lower part of the rotating shaft 6 is connected to the material strip 82 at uniform intervals along the circumferential direction, and the material strip 82 is connected to the isolation plate 7. Four extrusion frames 83 are slidably connected to the outer side of the partition 81 at uniform intervals along the circumferential direction. An elastic member 85 is connected between the extrusion frame 83 and the partition 81. The elastic member 85 is a pressure spring. The lower part of the extrusion frame 83 is rotatably connected to the rolling wheel 84, and the rolling wheel 84 contacts the isolation plate 7. The edge position of the material strip 82 is located on the inner side of the rolling wheel 84 to prevent the rolling wheel 84 from crushing the material strip 82.
[0030] like Figure 2As shown, a crushing tooth ring 10 is also included. The crushing tooth ring 10 is connected to the lower part of the processing chamber 2. The crushing tooth ring 10 is located above the isolation plate 7. When the quartz sand is thrown out and collides with the crushing tooth ring 10, the crushing tooth ring 10 can crush the quartz sand.
[0031] When it is necessary to process and crush the quartz sand, the device can be used. When in use, the quartz sand is first added into the feed pipe 31 through the lower hopper 34, and then the servo motor 33 can be controlled to drive the spiral feed shaft 32 to rotate, so that the quartz sand is transported to the processing bin 2 and falls on the top of the isolation plate 7, and then the drive motor 5 can be controlled to drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it can drive the material strip 82 to rotate. When the material strip 82 rotates, it can contact with the quartz sand and move the quartz sand, so that the quartz sand collides with the crushing tooth ring 10, and the quartz sand is crushed. The moved quartz sand is located on the outside of the top of the isolation plate 7 and under the rolling wheel 84. When the rotating shaft 6 rotates, it can drive the isolation plate 7 to rotate. When the isolation plate 7 rotates, it can drive the quartz sand on it to rotate. When the quartz sand rotates, it can contact the bottom of the rolling wheel 84, and the elastic member 85 can apply downward pressure to the extrusion frame 83 and the rolling wheel 84. The grinding wheel 84 is used to crush the quartz sand, thereby crushing and grinding the quartz sand. After grinding, gas can be injected into the lower part of the gas injection chamber 21 through the gas injection pipe 9, and the gas can enter the upper part of the isolation plate 7 through the gas injection hole and be discharged through the processing bin 2, the gas guide cylinder 3 and the discharge frame 4, thereby forming a gas flow channel between the processing bin 2, the gas guide cylinder 3 and the discharge frame 4, and the quartz sand ground to a suitable size will be blown by the gas and discharged along the airway through the discharge frame 4. Previously, a collection structure can be set at the discharge frame 4 to collect and process the quartz sand ground to a suitable size. In this way, the present device can be used to grind quartz sand, and after grinding, the quartz sand ground to a suitable size can be discharged through the airflow, while the quartz sand of unqualified size continues to be ground, which is more convenient to operate. In the actual operation process, the size of the blown quartz sand can be adjusted by controlling the intensity of the airflow.
[0032] like Figure 5 and Figure 6 As shown, a blocking mechanism is also included, which includes an air pipe 111, a sliding ring 112, a blocking ring 113 and an elastic member 114. The air injection holes of the air inlet ring 71 are all connected with the air pipe 111, the sliding ring 112 is slidably connected to the bottom of the isolation plate 7, and an elastic member 114 is connected between the sliding ring 112 and the isolation plate 7. The elastic member 114 is a connecting spring. The sliding ring 112 can block the bottom of the air pipe 111 when it moves upward. The blocking ring 113 is connected to the bottom of the isolation plate 7, and the outer arc surface of the blocking ring 113 is in contact with the inner arc surface of the sliding ring 112. The blocking ring 113 can block the gas to prevent the gas from entering the lower part of the processing chamber 2.
[0033] In the initial state, the barrier ring 113 blocks the bottom of the gas pipe 111 to prevent fine quartz sand powder from falling into the lower part of the processing chamber 2 through the gas pipe 111. When the gas is injected through the gas injection pipe 9, as the air pressure in the barrier ring 113 increases, the barrier ring 113 will be squeezed downward, and the elastic member 114 will be stretched. At this time, the gas pipe 111 is no longer blocked, and the gas can be injected into the upper part of the processing chamber 2 through the gas pipe 111, thereby blowing the quartz sand to move. When the gas supply is stopped, the elastic member 114 pulls the barrier ring 113 to reset, thereby blocking the gas pipe 111. In this way, the gas pipe 111 can be blocked when the gas supply is stopped, thereby preventing fine quartz sand powder from falling into the lower part of the processing chamber 2.
[0034] like Figure 7-Figure 9 As shown, it also includes a lifting mechanism, which includes a connecting ring 121, a turntable 122, a push plate 123 and an arc-shaped extrusion block 124. The turntable 122 is connected to the lower part of the rotating shaft 6, and the connecting ring 121 is rotatably connected to the lower part of the rotating shaft 6. The connecting ring 121 is located below the turntable 122, and four push plates 123 are slidably connected to the connecting ring 121 at uniform intervals along the circumferential direction. The side of the push plate 123 away from the rotating shaft 6 is connected to a convex shaft 125, an inclined groove is provided on the upper part of the extrusion frame 83, and the convex shaft 125 is located in the inclined groove. When the convex shaft 125 moves, it can push the extrusion frame 83 to move through the inclined groove, and four arc-shaped extrusion blocks 124 are connected to the bottom of the turntable 122 at uniform intervals along the circumferential direction, and the inner side of the push plate 123 is located at the moving track of the arc-shaped extrusion block 124.
[0035] When the rotating shaft 6 rotates, it can drive the turntable 122 to rotate. When the turntable 122 rotates, it drives the arc-shaped extrusion block 124 to rotate. When the arc-shaped extrusion block 124 rotates, it can contact the push plate 123, so that the push plate 123 is squeezed and moves horizontally in the radial direction away from the rotating shaft 6. When the push plate 123 moves, it can drive the cam 125 to move. When the cam 125 moves, it can drive the extrusion frame 83 to move upward through the inclined groove. The elastic member 85 is compressed, and the upward movement of the extrusion frame 83 can drive the rolling wheel 84 to move upward. When the arc-shaped extrusion block 124 rotates to disengage from the push plate 123, the extrusion frame 83 and the rolling wheel 84 move downward and reset under the action of the elastic member 85. This can be repeated, which can drive the rolling wheel 84 to move up and down repeatedly, strike the quartz sand, and assist in crushing the quartz sand, thereby improving the crushing effect of the quartz sand.
