Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to feeding equipment for quartz sand purification. Background Technology

[0002] Quartz sand purification is a process that removes impurities from quartz sand and increases its silica purity through physical, chemical, or combined physical and chemical methods to meet the demand for high-purity quartz sand in fields such as photovoltaics, electronics, optical glass, and high-end ceramics. In the continuous purification process, conveying equipment is required to continuously transport the quartz sand.

[0003] During the conveyor belt transport of sand and gravel, the sand and gravel are typically fed directly from the output end of other conveying equipment onto the outer surface of the conveyor belt, thus enabling their movement along the belt. However, some sand and gravel may accumulate excessively above the conveyor belt. When this accumulated sand and gravel enters the purification equipment via the conveyor belt, it causes a sharp increase in the feed rate. This situation may lead to blockages or malfunctions at the purification equipment's inlet, affecting the stability of the conveyor belt as a feeding device and resulting in instability during operation. Utility Model Content

[0004] The purpose of this invention is to address the issue of excessive accumulation of sand and gravel above the conveyor belt. When this sand and gravel enter the purification equipment via the conveyor belt, it causes a sharp increase in the feed rate. This situation may lead to blockage at the inlet of the purification equipment or abnormal operation, thereby affecting the stability of the conveyor belt as a feeding device and resulting in low stability during use. Therefore, this invention provides a feeding device for quartz sand purification.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for quartz sand purification, comprising a frame, a plurality of support legs at the bottom of the frame, rotating rollers rotatably connected to both ends of the frame, a conveyor belt sleeved on the outer surface of the rotating rollers, a servo motor at one end of the frame, the output end of the servo motor being connected to one end of a rotating roller via a belt pulley set, a plurality of idler rollers on the outer surface of the frame, and an anti-piling device at one end of the frame to prevent the sand and gravel conveyed on the conveyor belt from accumulating too high.

[0006] The effect achieved by the above components is as follows: when using the feeding equipment, the sand and gravel are poured onto the lower end of the conveyor belt by the sand and gravel transfer equipment. The servo motor at the operating end drives a rotating roller to rotate through the belt pulley set, so that the conveyor belt moves on the outer surface of the rotating roller. The sand and gravel on the surface are transported to the upper end of the conveyor belt through the conveyor belt, so that the sand and gravel enter the quartz sand purification equipment for feeding.

[0007] Preferably, the anti-stacking device includes a frame rod, with both ends of the frame rod fixedly connected to both sides of the machine frame. An electric push rod is provided at the top of the frame rod, and a rectangular rod is installed at the bottom of the output rod of the electric push rod. The two ends of the rectangular rod slide on both sides of the inner wall of the frame rod. Two round rods are slidably connected to the inner wall of the rectangular rod. The diameter of the part of the round rod protruding from the top of the rectangular rod is larger than the diameter inside the rectangular rod. A stop block is fixedly connected to the bottom of the round rod. The stop block is made of rubber and has a hollow interior in the middle. The surface of the stop block facing the conveyor belt is inclined.

[0008] The effect achieved by the above components is as follows: When the feeding equipment is working, if some sand and gravel are moved to the bottom side of the stop during the movement of the conveyor belt, the part of the sand and gravel that is higher than the bottom of the stop will contact the outer surface of the stop and squeeze the stop. The stop blocks the part of the sand and gravel that is too high, so that the sand and gravel move backward, and avoids the sand and gravel accumulating too high on the outer surface of the conveyor belt as much as possible. When outputting through the outer surface of the conveyor belt, too much sand and gravel is output at one time. At the same time, the electric push rod can be operated to control the electric push rod to retract and drive the two ends of the rectangular rod to slide up and down on both sides of the inner wall of the frame, adjust the height position of the stop, and change the blocking height of the stop.

[0009] Preferably, a protruding plate is fixedly connected to each end of the stop block, and the protruding plate protrudes from the edges of both ends of the stop block.

[0010] The effect achieved by the above components is as follows: when the sand and gravel located above the conveyor belt comes into contact with one side of the stop and pushes the middle position of the outer surface of the rubber stop to be recessed inward, the convex plates at both ends of the stop will tilt towards the middle. The convex plates can further restrict the position of the sand and gravel near the two ends of the stop on the conveyor belt, and prevent the sand and gravel from detaching from the outer surface of the conveyor belt when it comes into contact with the stop.

[0011] Preferably, a wear-resistant plate is fixedly connected to the bottom end of the stop block, and the bottom edge of the wear-resistant plate is arc-shaped.

[0012] The effect achieved by the above components is that by setting an arc-shaped wear-resistant plate at the bottom of the block, the wear resistance of the outer surface at the contact point between the bottom of the block and the sand and gravel can be further improved, thereby increasing the service life of the anti-piling device.

[0013] Preferably, a baffle is fixedly connected to the side of the outer surface of the block near the wear-resistant sheet, and the baffle and the top of the block form a certain angle.

[0014] The effect achieved by the above components is that when the sand and gravel on the conveyor belt accumulates too high, the baffle can further restrict the position of the blocked sand and gravel by contacting one side of the baffle, thus preventing the sand and gravel from entering above the top of the baffle.

[0015] Preferably, a spring is provided on the outer surface of the round rod, and the upper and lower ends of the spring are fixedly connected to one side of the round rod and one side of the bottom end of the rectangular rod, respectively.

[0016] The effect achieved by the above components is as follows: when the block blocks excessively piled sand and gravel, the force on one side will push the block to slide upward through the round rod on the inner wall of the rectangular rod and compress the spring, so that the block can move up and down within a small range when blocking sand and gravel, thereby improving the buffering effect when blocking sand and gravel.

[0017] Preferably, the two ends of the rectangular rod are fixedly connected to support rods, and the end of the support rod away from the rectangular rod is rotatably connected to a wheel, which rolls on the inner wall of the frame rod.

[0018] The effect achieved by the above components is that when the rectangular rod moves up and down, the rollers at one end of the two support rods will roll on both sides of the inner wall of the frame rod. The support rods further restrict the angle between the rectangular rod and the frame rod, increasing the stability of the rectangular rod when it moves and improving the balance of the left and right ends of the rectangular rod.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by setting up an anti-piling device, a stop block is installed at the higher end of the frame. The height of the stop block above the conveyor belt can be adjusted by operating an electric push rod. The part of the sand and gravel that accumulates too high on the conveyor belt will be blocked by the bottom of the stop block, causing the accumulated sand and gravel to move to the rear of the outer surface of the conveyor belt. This avoids the sand and gravel being discharged too much at once when it passes through the outer surface of the conveyor belt, thus improving the stability of the feeding equipment during use.

[0027] Example 1, such as Figure 1-2 As shown, the feeding equipment for quartz sand purification includes a frame 1. Several support legs are provided at the bottom of the frame 1. Rotary rollers 3 are rotatably connected to both ends of the frame 1. A conveyor belt 4 is fitted on the outer surface of the rotary rollers 3. A servo motor 6 is provided at one end of the frame 1. The output end of the servo motor 6 is connected to one end of a rotary roller 3 through a belt pulley set. Several idler rollers 5 are provided on the outer surface of the frame 1. An anti-piling device 2 is provided at one end of the frame 1 to prevent the sand and gravel conveyed on the conveyor belt 4 from piling up too high. When using the feeding equipment, the sand and gravel are poured onto the lower end of the conveyor belt 4 by the sand and gravel transfer equipment. The servo motor 6 at one end drives a rotary roller 3 to rotate through the belt pulley set, causing the conveyor belt 4 to move on the outer surface of the rotary roller 3. The sand and gravel on the surface are conveyed to the upper end of the conveyor belt 4 through the conveyor belt 4, so that the sand and gravel enter the quartz sand purification equipment for feeding.

[0028] Reference Figure 1-5As shown in this embodiment: the anti-piling device 2 includes a frame rod 21, with both ends of the frame rod 21 fixedly connected to both sides of the frame 1. An electric push rod 22 is installed at the top of the frame rod 21, and a rectangular rod 23 is installed at the bottom of the output rod of the electric push rod 22. The two ends of the rectangular rod 23 slide on both sides of the inner wall of the frame rod 21. Two round rods 24 are slidably connected to the inner wall of the rectangular rod 23. The diameter of the portion of the round rod 24 protruding from the top of the rectangular rod 23 is larger than the diameter inside the rectangular rod 23. A stop block 25 is fixedly connected to the bottom of the round rod 24. The stop block 25 is made of rubber and has a hollow interior. The surface of the stop block 25 facing the conveyor belt 4 is inclined. By setting the stop block 25, when the feeding equipment is working, if some sand and gravel are moved to the bottom side of the stop block 25 during the movement of the conveyor belt 4, the portion of the sand and gravel exceeding the bottom of the stop block 25 will contact the outer surface of the stop block 25 and press against it. 5. The block 25 blocks the excessively high portion of sand and gravel, causing the sand and gravel to move backward. This minimizes the accumulation of sand and gravel on the outer surface of the conveyor belt 4, preventing excessive output of sand and gravel at a time. Simultaneously, the electric push rod 22 can be operated to control its retraction, causing the two ends of the rectangular rod 23 to slide up and down on both sides of the inner wall of the frame rod 21, adjusting the height of the block 25 and changing its blocking height. By setting up the anti-piling device 2, and installing the block 25 at the higher end of the frame 1, the electric push rod 22 can adjust the height of the block 25 above the conveyor belt 4. The excessively high accumulation of sand and gravel on the conveyor belt 4 will be blocked by the bottom of the block 25, causing the accumulated sand and gravel to move backward on the outer surface of the conveyor belt 4. This minimizes the output of sand and gravel at a time, improving the stability of the feeding equipment during use.

[0029] Reference Figure 2-5 As shown in this embodiment: The two ends of the stop block 25 are respectively fixedly connected with protruding plates 26. The protruding plates 26 protrude from the edges of the two ends of the stop block 25. When the sand and gravel above the conveyor belt 4 contacts one side of the stop block 25 and pushes the middle position of the outer surface of the rubber stop block 25 inward, the protruding plates 26 at both ends of the stop block 25 will tilt towards the middle. The protruding plates 26 can further restrict the position of the sand and gravel near the two ends of the stop block 25 on the conveyor belt 4, preventing the sand and gravel from detaching from the outer surface of the conveyor belt 4 when in contact with the stop block 25. The bottom end of the stop block 25 is fixedly connected with a wear-resistant plate 27. The bottom edge of the wear-resistant plate 27 is arc-shaped. By setting an arc-shaped wear-resistant plate 27 at the bottom end of the stop block 25, the wear resistance of the outer surface at the contact point between the bottom end of the stop block 25 and the sand and gravel can be further improved, thus increasing the service life of the anti-piling device 2.

[0030] Reference Figure 2-5As shown in this embodiment: a baffle 28 is fixedly connected to the side of the outer surface of the stop block 25 near the wear-resistant plate 27. The baffle 28 and the top of the stop block 25 form a certain angle. When the sand and gravel on the conveyor belt 4 accumulate too high, it contacts one side of the stop block 25. Through the baffle 28, the position of the blocked sand and gravel can be further restricted, preventing the sand and gravel from entering above the top of the baffle 28. A spring 29 is provided on the outer surface of the round rod 24. The upper and lower ends of the spring 29 are fixedly connected to one side of the round rod 24 and one side of the bottom of the rectangular rod 23, respectively. When the stop block 25 blocks the sand and gravel that have accumulated too high, the force on one side will push the stop block 25 through the round rod 24 and onto the rectangular rod 23. The inner wall slides upward a certain distance and compresses the spring 29, so that the stop block 25 can move up and down within a small range when blocking sand and gravel, thereby improving the buffering effect when blocking sand and gravel. The two ends of the rectangular rod 23 are respectively fixedly connected to the support rods 210. The end of the support rod 210 away from the rectangular rod 23 is rotatably connected to the wheel. The wheel rolls on the inner wall of the frame rod 21. When the rectangular rod 23 moves up and down, the wheels at one end of the two support rods 210 will roll on both sides of the inner wall of the frame rod 21. The angle between the rectangular rod 23 and the frame rod 21 is further restricted by the support rods 210, thereby increasing the stability of the rectangular rod 23 when it moves and improving the balance of the left and right ends of the rectangular rod 23.

[0031] Working Principle: When using the feeding equipment, sand and gravel are poured onto the lower end of the conveyor belt 4 via a sand and gravel transfer device. A servo motor 6 at one end drives a rotating roller 3 via a belt pulley set, causing the conveyor belt 4 to move on the outer surface of the roller 3. The conveyor belt 4 transports the sand and gravel towards the upper end, allowing it to enter the quartz sand purification equipment for feeding. During the movement of the conveyor belt 4, if the sand and gravel are moved to the bottom of the stop block 25 and there is excessive accumulation, the portion of the sand and gravel exceeding the bottom of the stop block 25 will contact and press against the outer surface of the stop block 25. The stop block 25 blocks the excessively high portion of the sand and gravel, causing it to move backward, minimizing excessive accumulation on the outer surface of the conveyor belt 4. This ensures that the sand and gravel are output through the outer surface of the conveyor belt 4 in a single pass. When too much sand and gravel comes into contact with one side of the stop block 25 and pushes the middle of the outer surface of the rubber stop block 25 inward, the convex plates 26 at both ends of the stop block 25 will tilt towards the middle. The convex plates 26 can further restrict the position of the sand and gravel near the ends of the stop block 25 on the conveyor belt 4. The operation of the electric push rod 22 can control the electric push rod 22 to retract and drive the two ends of the rectangular rod 23 to slide up and down on both sides of the inner wall of the frame rod 21, adjust the height position of the stop block 25, and change the blocking height of the stop block 25. When the rectangular rod 23 moves up and down, the rollers at one end of the two support rods 210 will roll on both sides of the inner wall of the frame rod 21. The support rods 210 further restrict the angle between the rectangular rod 23 and the frame rod 21, increase the stability of the rectangular rod 23 when it moves, and improve the balance of the left and right ends of the rectangular rod 23.
