Description

Technical Field

[0001] The invention relates to the technical field of screening, in particular to a quartz sand screening device. Background Art

[0002] Quartz sand is a kind of sandstone mainly composed of silicon dioxide, which is commonly used in the fields of construction, glass manufacturing, cement and ceramic industries. After the quartz sand is crushed, in order to remove impurities and particles that do not meet the specifications, it needs to be screened to ensure the quality and specifications of the quartz sand. In the screening process, a vibrating screen is usually used to screen it. The quartz sand contains some fine particles or sticky substances, which are easy to cause the sieve holes to be blocked, affecting the screening effect. When the screen is blocked, the efficiency of the quartz sand on the top of the screen falling down will be reduced. When the vibrating screen in the prior art is screening the quartz sand, it is impossible to adjust the amount of quartz sand feeding in real time. When the screen is blocked, if the rear continues to feed the quartz sand with the same amount, it will cause too much quartz sand to accumulate on the top of the screen, which will lead to a decrease in screening efficiency. Since the screen cannot pass the quartz sand smoothly, it will affect the screening quality of the product. If the screen cannot be cleared in time, it will cause the screen to be seriously blocked, and even need to be shut down for maintenance, thereby affecting the screening efficiency of quartz sand.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a quartz sand screening device, which includes a screening component 100, a quantitative component 200 and a dredging component 300, the cooperation of which can improve the screening efficiency of quartz sand.

[0032] The screening assembly 100 includes a support frame 101 , a vibration frame 102 , a screen 103 and a loading plate 104 . The vibration frame 102 is disposed in the support frame 101 , the screen 103 is fixed in the vibration frame 102 , and the loading plate 104 is located on the top of the support frame 101 .

[0033] One side of the vibration frame 102 is rotatably connected to a support rod, and the other end of the support rod is rotatably connected to the support frame 101. The vibration frame 102 and the support frame 101 are connected by four support rod connecting rods. A vibration motor is arranged at the bottom of the vibration frame 102. The vibration frame 102 and the loading plate 104 are both inclined. Stabilizing plates are fixed on both sides of the top of the support frame 101, and the loading plate 104 is rotatably connected to the stabilizing plate through a rotating shaft.

[0034] The crushed quartz sand is transported to the top of the loading plate 104 through the conveyor belt, and the quartz sand is transported to the top of the screen 103 through the loading plate 104. At this time, the vibration frame 102 is driven to vibrate by the vibration motor, so that the quartz sand can be screened. This is the existing technology and will not be elaborated in this solution.

[0035] The quantitative component 200 is arranged on the support frame 101, and includes an adjusting member 201, a pushing member 202 and a sensing member 203. The adjusting member 201 is located at the top of the support frame 101, the pushing member 202 is arranged on one side of the adjusting member 201, and the sensing member 203 is located above the vibration frame 102.

[0036] When the screen 103 is blocked, the amount of quartz sand on the top of the screen 103 that falls down will decrease. When a large amount of quartz sand cannot fall down, the quartz sand on the top of the screen 103 will continue to increase, and the height of the quartz sand accumulation will continue to increase. At this time, the quartz sand that is accumulated too high will push the sensing member 203 to move upward, and the sensing member 203 will drive the pushing member 202 to move, and the pushing member 202 will drive the adjusting member 201 to rotate, and the adjusting member 201 will drive the feeding plate 104 to rotate to a horizontal angle, and at the same time, the quartz sand on the top of the feeding plate 104 will be intercepted, so as to reduce the amount of quartz sand fed, and avoid the quartz sand on the top of the screen 103 from continuing to accumulate, resulting in a more serious blockage of the screen 103.

[0037] The dredging component 300 is arranged in the support frame 101, and includes an impact member 301, a rotating member 302 and a moving member 303. The impact member 301 is arranged above the screen 103, the rotating member 302 is located on the impact member 301, and the moving member 303 is arranged on one side of the vibration frame 102.

[0038] When the screen 103 is clogged, the impact member 301 will start and impact the top of the screen 103. The impact will generate a vibration force, which will be transmitted to the blockage through the screen 103, helping to shake the blockage off the screen 103, thereby effectively removing impurities or particles on the screen 103 and restoring the normal screening function of the screen 103. The rotating member 302 is set to push the impact member 301 to move upward, so that the impact member 301 can move downward and impact the screen 103. The moving member 303 is set to push the rotating member 302 to rotate, so that the rotating member 302 can drive the impact member 301 to move upward.

[0039] Example 2

[0040] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the adjusting member 201 includes a fixed frame 201a, a force block 201b, an extrusion block 201c, a movable block 201d, a rotating column 201e, a fixed shaft 201f and a baffle 201g. The fixed frame 201a is fixed to the top of the support frame 101, one side of the force block 201b is fixed to the loading plate 104, the extrusion block 201c is located at the top of the fixed frame 201a, the movable block 201d is fixed to the bottom of the extrusion block 201c, the rotating column 201e is rotatably connected to the fixed frame 201a, the fixed shaft 201f is fixed in the movable block 201d, and the baffle 201g is located on one side of the loading plate 104.

[0042] One side of the squeezing block 201c is inclined, and the movable block 201d is located outside the rotating column 201e. The rotating column 201e is provided with a spiral groove, and the fixed shaft 201f slides in the spiral groove.

[0043] When the rotating column 201e rotates, it will drive the fixed shaft 201f to slide in the spiral groove, and the cooperation between the two will drive the movable block 201d to move, and the movable block 201d will drive the extrusion block 201c to move, so that the extrusion block 201c will squeeze the force block 201b on the inclined surface, thereby pushing the force block 201b to move upward, and the force block 201b will drive one side of the loading plate 104 to rotate upward, and then the loading plate 104 can be adjusted to a horizontal angle, thereby reducing the speed at which the loading plate 104 loads the top of the screen 103, thereby avoiding excessive accumulation of quartz sand on the top of the screen 103.

[0044] The baffle 201g is fixed to one side of the fixed frame 201a through the mounting block. When the loading plate 104 is in the initial state, there is a certain space between the bottom of the baffle 201g and the loading plate 104, so that the quartz sand can flow downward through the space between the two. When the loading plate 104 rotates to a horizontal state, the space between the two will be reduced, which can slow down the falling of the quartz sand and intercept part of the quartz sand at the same time.

[0045] Both ends of the rotating column 201e extend to the outside of the fixed frame 201a. A torsion spring is fixed to one side of the fixed frame 201a. One end of the torsion spring is fixed to the rotating column 201e. The torsion spring applies a rotational force to the rotating column 201e, so that the rotating column 201e can be reset after rotation.

[0046] There are two force blocks 201b, two squeeze blocks 201c, two movable blocks 201d and two fixed shafts 201f, which are respectively located on both sides of the loading plate 104, and the spiral grooves at both ends of the rotating column 201e are in opposite directions.

[0047] Specifically, the pushing member 202 includes a rotating rod 202a, a movable frame 202b, a push rod 202c and a push block 202d. The rotating rod 202a is fixed to one side of the rotating column 201e, the movable frame 202b is located outside the rotating rod 202a, the push rod 202c is arranged on one side of the movable frame 202b, and the push block 202d is located at one end of the push rod 202c.

[0048] The movable frame 202b is movably connected to the outer side of the rotating rod 202a, one end of the push rod 202c is connected to the hinge plate and hinged to the movable frame 202b, a plurality of stable frames are fixed on the top of the support frame 101, the push rod 202c is movably connected to the inside of the stable frame, one side of the push block 202d is inclined, and the inclined surface of the push block 202d contacts the end of the push rod 202c.

[0049] When the push block 202d rotates downward, its inclined surface will squeeze the end of the push rod 202c, thereby pushing the push rod 202c to move, and driving the movable frame 202b and the rotating rod 202a to rotate through the push rod 202c, so that the rotating column 201e can be driven to rotate through the rotating rod 202a.

[0050] Specifically, the sensing element 203 includes a rotating plate 203a, a connecting block 203b, a fixed column 203c, a fixed plate 203d and a first spring 203e. The rotating plate 203a is located above the screen 103, the connecting block 203b is fixed to the top of the rotating plate 203a, the fixed column 203c is rotatably connected to the outside of the connecting block 203b, the fixed plate 203d is located above the rotating plate 203a, and both ends of the first spring 203e are respectively fixed to the fixed plate 203d and the rotating plate 203a.

[0051] One side of the push block 202d is fixed to the rotating plate 203a, and positioning blocks are fixed on both sides of the top of the support frame 101. The two ends of the fixed column 203c are respectively fixed to the two positioning blocks. The rotating plate 203a is inclined in the initial state, and its downward inclined side is close to the screen 103. When the quartz sand on the top of the screen 103 is normally screened downward, the quartz sand on the top of the screen 103 will not contact the rotating plate 203a, and the fixed plate 203d is fixed to the fixed column 203c through the connecting frame.

[0052] When the screen 103 is blocked, the amount of quartz sand on the top of the screen 103 that falls down will decrease. When a large amount of quartz sand cannot fall down, the quartz sand on the top of the screen 103 will continue to increase, and the height of the quartz sand accumulation will continue to increase. At this time, the quartz sand that is accumulated too high will contact the rotating plate 203a when moving, and push one side of the rotating plate 203a to move upward. At this time, the other side of the rotating plate 203a will move downward, and drive the push block 202d to move downward, so that the push block 202d can squeeze the end of the push rod 202c.

[0053] When the screen 103 is unblocked and the amount of quartz sand on the top thereof returns to normal, the first spring 203e applies a thrust to the rotating plate 203a, so that the rotating plate 203a can be reset.

[0054] Specifically, the impact member 301 includes a support plate 301a, a movable rod 301b, an impact plate 301c, a mounting plate 301d and a second spring 301e. The support plate 301a is located on the inner side of the support frame 101, the movable rod 301b is inserted into the support plate 301a, the impact plate 301c is fixed to the bottom of the movable rod 301b, the mounting plate 301d is fixed to the top of the movable rod 301b, and the two ends of the second spring 301e are respectively fixed to the mounting plate 301d and the support plate 301a.

[0055] There are two groups of impact members 301, which are respectively located at two sides of the top of the screen 103. The movable rod 301b is movably connected to the support plate 301a, and the impact plate 301c is made of rubber.

[0056] When the supporting plate 301a moves downward, it will drive the movable rod 301b and the impact plate 301c to move downward, so that the bottom of the impact plate 301c can contact the screen 103; when the mounting plate 301d moves upward, it will drive the impact plate 301c to separate from the screen 103 and stretch the second spring 301e at the same time. At this time, the second spring 301e applies a downward pulling force to the mounting plate 301d, so that the mounting plate 301d drives the movable rod 301b and the impact plate 301c to move downward quickly, so that the top of the screen 103 can be impacted by the impact plate 301c. The impact will generate a vibration force, which will be transmitted to the blockage through the screen 103, which will help to shake the blockage off the screen 103, and then effectively remove the impurities or particles on the screen 103, and restore the normal screening function of the screen 103.

[0057] Specifically, the impact member 301 also includes a support column 301f, a support block 301g and a third spring 301h. The support column 301f is inserted into the support plate 301a, the support block 301g is fixed to the bottom end of the support column 301f, and both ends of the third spring 301h are respectively fixed to the support block 301g and the support plate 301a.

[0058] There are two support columns 301f, which are located on both sides of the support plate 301a. The support columns 301f are movably connected to the support plate 301a. The support columns 301f are used to support and position the support plate 301a to prevent it from shifting when moving. The third spring 301h applies an upward supporting force to the support plate 301a to prevent the support plate 301a from moving downward during normal use of the screen 103, causing the impact plate 301c to continuously impact the screen 103, which will not only affect the normal screening of the screen 103, but also cause damage to the screen 103.

[0059] Example 3

[0060] Reference Figure 1-Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0061] Specifically, the impact member 301 also includes a fixed sleeve 301i, a force column 301j and a fourth spring 301k. The fixed sleeve 301i is fixed to the top of the support plate 301a, the force column 301j is located in the fixed sleeve 301i, and both ends of the fourth spring 301k are respectively fixed to the force column 301j and the inner wall of the fixed sleeve 301i.

[0062] The top of the force-bearing column 301j is in contact with the rotating plate 203a. When one side of the rotating plate 203a rotates downward, it will simultaneously push the force-bearing column 301j to move downward. When the force-bearing column 301j moves downward, it will drive the fixing sleeve 301i to move downward through the fourth spring 301k, so that the fixing sleeve 301i can drive the supporting plate 301a to move downward, and make the bottom of the impact plate 301c contact with the screen 103.

[0063] The elastic force of the fourth spring 301k is greater than that of the third spring 301h.

[0064] Specifically, the rotating member 302 includes a rotating rod 302a, a fixed block 302b and a force rod 302c. The rotating rod 302a is located in the supporting plate 301a, the fixed block 302b is fixed to the top of the rotating rod 302a, and the force rod 302c is fixed to one side of the mounting plate 301d.

[0065] The number of rotating parts 302 corresponds to the impact part 301. A groove is provided on the support plate 301a. The rotating rod 302a is rotatably connected to the groove through a rotating shaft. The outer side of the fixed block 302b is annular, and the rotating rod 302a is L-shaped. When the rotating rod 302a rotates, it will drive the fixed block 302b to squeeze the force-bearing rod 302c, thereby pushing the force-bearing rod 302c to move upward, and driving the mounting plate 301d to move upward through the force-bearing rod 302c, so that the impact plate 301c can be separated from the screen 103 through the mounting plate 301d.

[0066] Specifically, the moving part 303 includes a supporting sleeve 303a, a sensing ball 303b, a push post 303c and a positioning plate 303d. One side of the supporting sleeve 303a is fixed to the vibration frame 102, the sensing ball 303b is located in the supporting sleeve 303a, the push post 303c is inserted in the supporting sleeve 303a, and the positioning plate 303d is fixed to one end of the push post 303c.

[0067] The number of movable parts 303 corresponds to that of rotating parts 302. The sensing ball 303b is movably connected to the support sleeve 303a, and the sensing ball 303b itself has a certain weight. One side of the positioning plate 303d contacts the sensing ball 303b. One end of the push column 303c penetrates to the outside of the support sleeve 303a and is movably connected to the support sleeve 303a.

[0068] When the support plate 301a moves downward, it will also drive the rotating rod 302a to move downward, and move the rotating rod 302a to a height where it can contact the push column 303c. When the vibration frame 102 swings to screen the quartz sand, it will cause the sensing ball 303b to swing simultaneously in the support sleeve 303a, so that the sensing ball 303b can reciprocate in the support sleeve 303a. When the sensing ball 303b moves toward the outside of the support sleeve 303a, it will push the positioning plate 303d to move, so that the positioning plate 303d drives the push column 303c to move, and the end of the push column 303c squeezes the bottom of the rotating rod 302a, thereby pushing the rotating rod 302a to rotate, and then the fixed block 302b can be driven by the top of the rotating rod 302a to squeeze the force-bearing rod 302c.

[0069] When the sensing ball 303b moves back and forth in the support sleeve 303a, when it moves in the direction of the positioning plate 303d, it will push the positioning plate 303d to move. When it moves in the direction away from the positioning plate 303d, the fifth spring 303e can apply a thrust to the positioning plate 303d, so that the positioning plate 303d will follow the sensing ball 303b to reset. Then, when the sensing ball 303b moves in the direction of the positioning plate 303d again, it can push the positioning plate 303d to move again, so that the impact plate 301c can repeatedly impact the screen 103 until the screen 103 recovers its normal screening effect.

[0070] Specifically, the moving member 303 further includes a fifth spring 303e, and two ends of the fifth spring 303e are respectively fixed to the positioning plate 303d and the inner wall of the supporting sleeve 303a.

[0071] When in use, when the screen 103 is blocked, the amount of quartz sand on the top of the screen 103 that falls downward will decrease. When a large amount of quartz sand cannot fall downward, the quartz sand on the top of the screen 103 will continue to increase, and the height of the quartz sand accumulation will continue to increase. At this time, the quartz sand that is accumulated too high will contact the rotating plate 203a when moving, and push one side of the rotating plate 203a to move upward. At this time, the other side of the rotating plate 203a will move downward and drive the push block 202d to move downward. When the push block 202d rotates downward, its inclined surface will squeeze the end of the push rod 202c, thereby pushing the push rod 202c to move, and the movable frame 202b and the rotating rod 202a are driven to rotate through the push rod 202c, so that the rotating column 201e can be driven to rotate through the rotating rod 202a.

[0072] When the rotating column 201e rotates, it will drive the fixed shaft 201f to slide in the spiral groove, and the cooperation between the two will drive the movable block 201d to move, and the movable block 201d will drive the extrusion block 201c to move, so that the extrusion block 201c will squeeze the force block 201b on the inclined surface, thereby pushing the force block 201b to move upward, and the force block 201b will drive one side of the loading plate 104 to rotate upward, and then the loading plate 104 can be adjusted to a horizontal angle, thereby reducing the speed at which the loading plate 104 loads the top of the screen 103, thereby avoiding excessive accumulation of quartz sand on the top of the screen 103.

[0073] At the same time, when one side of the rotating plate 203a rotates downward, it will push the force-bearing column 301j to move downward at the same time. When the force-bearing column 301j moves downward, it will drive the fixed sleeve 301i to move downward through the fourth spring 301k, so that the fixed sleeve 301i can drive the support plate 301a to move downward. When the support plate 301a moves downward, it will drive the movable rod 301b and the impact plate 301c to move downward, so that the bottom of the impact plate 301c can contact the screen 103.

[0074] When the support plate 301a moves downward, it will also drive the rotating rod 302a to move downward, and move the rotating rod 302a to a height where it can contact the push pin 303c. When the vibration frame 102 swings in the direction of discharging, it will drive the sensing ball 303b to move in the support sleeve 303a, and push the positioning plate 303d to move through the sensing ball 303b, so that the positioning plate 303d drives the push pin 303c to move, and the end of the push pin 303c squeezes the bottom of the rotating rod 302a, thereby pushing the rotating rod 302a to rotate.

[0075] When the rotating rod 302a rotates, it will drive the fixed block 302b to squeeze the force-bearing rod 302c, thereby pushing the force-bearing rod 302c to move upward, and driving the mounting plate 301d to move upward through the force-bearing rod 302c, so that the mounting plate 301d can drive the impact plate 301c to separate from the screen 103, and at the same time stretch the second spring 301e. At this time, the second spring 301e applies a downward pulling force to the mounting plate 301d, so that the mounting plate 301d drives the movable rod 301b and the impact plate 301c to move downward quickly, so that the top of the screen 103 can be impacted by the impact plate 301c. The impact will generate a vibration force, which will be transmitted to the blockage through the screen 103, which will help to shake the blockage off the screen 103, and then the impurities or particles on the screen 103 can be effectively removed, and the normal screening function of the screen 103 can be restored.
