Description

Technical Field

[0001] The present invention relates to a feed dredging device, in particular to a feed dredging device for processing high-purity quartz sand, which is applied in the technical field of quartz sand processing. Background Art

[0002] Quartz sand plays an indispensable role in numerous key industrial sectors, from basic glassmaking to high-tech semiconductor and photovoltaic industries. As a core raw material in the glass industry, quartz sand ensures the transparency and durability of glass products; in ceramics and refractory materials, it enhances the high-temperature resistance and chemical stability of products; in the metallurgical industry, quartz sand serves as an additive to optimize alloy properties; and it is also a key raw material in various industries, including construction and the chemical industry. In particular, in high-tech fields such as semiconductors and photovoltaics, high-purity quartz sand has become a key material for the manufacture of core components such as integrated circuits and solar panels, driving innovation and development in these industries. Quartz sand requires pulverization during processing.

[0003] The specification of Chinese patent CN206996806U discloses a "feed dredging device for quartz sand production". The material is directly put into the circular feed port, and then falls into the interior through the filter plate. Then, the driving motor drives the stirring rake to rotate accordingly to achieve stirring and dispersion of the material, thereby achieving actual clearing and accelerating feeding. The specification of Chinese patent CN214812456U discloses a "feed dredging device for quartz sand production". This quartz sand production feed dredging device has a simple structure. An anti-blocking device is provided on the feed port of the feed pipe. By using the mutual cooperation between the anti-blocking device and the circular filter, blockage in the feeding process can be effectively avoided. At the same time, the efficiency of material feeding can also be accelerated, thereby fundamentally improving production efficiency, being practical and easy to promote. At present, in order to make the feeding of quartz sand particles more dispersed, most of the quartz sand particles are stirred and dispersed by using a filter screen. However, when a large number of quartz sand particles are accumulated on the filter screen, the feeding dredging effect of the quartz sand particles is easily affected, which is not conducive to the processing of quartz sand. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that a large amount of quartz sand particles accumulated on the traditional filter screen easily affects the feed dredging effect, which is not conducive to the processing of quartz sand.

[0005] In order to solve the above problems, the present invention provides a feeding dredging device for processing high-purity quartz sand, comprising a feeding hopper body, a weighing plate fixedly connected to the interior of the feeding hopper body, a material-passing bulge evenly fixedly connected to the upper surface of the weighing plate, a material-passing bulge having a side surface provided with a material-dropping opening communicated with the lower surface of the weighing plate, a lifting bracket telescopically connected to the top of the feeding hopper body, a rotating shaft module fixedly connected to the middle of the lifting bracket, a pushing rotary frame fixedly connected to the output end of the rotating shaft module, rotating wheels rotatably connected to both ends of the pushing rotary frame, a pushing broom ring movably sleeved between the two rotating wheels, and the pushing broom ring movably connected to the upper surface of the weighing plate; The connecting end of the weighing plate and the feed hopper body is fixedly connected with a temporary storage ring groove, which is lower than the upper surface of the weighing plate, and the bottom of the temporary storage ring groove is lifted and connected with a ring-shaped pad. The upper surface of the ring-shaped pad is arranged in an inclined surface, and the lower end of the inclined surface of the ring-shaped pad is parallel to the upper surface of the weighing plate, and the bottom of the pushing broom ring is movably connected to the upper surface of the ring-shaped pad.

[0006] In the above-mentioned feeding and dredging device for high-purity quartz sand processing, the quartz sand particles entering the feed hopper body are weighed by a weighing plate, and the rotation direction of the pushing broom ring is adjusted according to the weighing result, the excess quartz sand is pushed into the temporary storage ring groove and the quartz sand in the temporary storage ring groove is replenished back to the weighing plate, so that an appropriate amount of quartz sand is maintained on the weighing plate, effectively improving the dredging effect of the quartz sand feeding.

[0007] As a further improvement of the present application, one of the two rotating wheels is fixedly connected to a driving module, which adopts a forward and reverse servo motor. By controlling the forward and reverse rotation of the driving module, the rotation direction of the pusher broom ring is regulated.

[0008] As a further improvement of the present application, a broom ring support is fixedly connected to the bottom of one end of the pusher rotary frame, and the broom ring support is slidingly connected to the bottom of one end of the pusher broom ring. The pusher broom ring is made of wear-resistant plastic fiber. The broom ring support is used to lift one end of the pusher broom ring, so that the pusher broom ring only has a one-way impact on the quartz sand.

[0009] As a further improvement of the present application, the bottom end of the rotating shaft module is rotatably connected to a bracket, and the top of the bracket is evenly fixedly connected to a bulge filling block, the bulge filling block vertically corresponds to the material bulge, and the bulge filling block is plugged into and corresponds to the lower opening of the blanking port. When the lifting bracket drives the rotating shaft module to move upward, it simultaneously drives the bracket to move upward, so that the bulge filling block blocks the blanking port and cuts off the feed supply of quartz sand.

[0010] As another improvement of the present application, both ends of the bottom of the bracket are fixedly connected to limiting columns, and both ends of the bottom of the feed hopper body are provided with limiting holes. The limiting columns and the limiting holes are plugged into each other, and the rotation of the bracket is limited by plugging the limiting columns and the limiting holes, thereby preventing the bracket from rotating with the push-material rotary frame.

[0011] As another improved supplement to the present application, the interior of the bulge filling block is hollow, and the top of the bulge filling block is fixedly connected to a telescopic bag, which is made of elastic rubber material. The elasticity of the telescopic bag is used to achieve buffering during the combination process of the bulge filling block and the blanking port.

[0012] As another improved supplement to the present application, a hard cover is fixedly embedded inside the top of the telescopic bag, and a protruding port is opened at one end of the hard cover. A clearing tongue piece is fixedly connected to the inside of the bulge filling block, and the clearing tongue piece passes through the protruding port, and the clearing tongue piece corresponds to the upper port of the blanking port. After the bulge filling block is combined with the blanking port, the clearing tongue piece extended outward from the protruding port can clear and clean the upper port of the blanking port.

[0013] As another improvement of the present application, the clearing tongue piece is curved in an arc shape, and the curved portion of the clearing tongue piece is slidably connected to the hard cover. The clearing tongue piece is made of spring steel material, and the elasticity of the clearing tongue piece is utilized to realize automatic lifting of the telescopic bag, and the elasticity of the clearing tongue piece is utilized to enhance the buffering capacity of the telescopic bag.

[0014] In summary, the present invention weighs the quartz sand particles entering the feed hopper body through a weighing tray, and adjusts the rotation direction of the pushing broom ring according to the weighing result. When the total amount of quartz sand on the weighing tray is too large, the pushing broom ring pushes the excess quartz sand into the temporary storage ring groove, thereby reducing the total amount of quartz sand particles on the weighing tray without affecting the passage of the quartz sand particles through the drop port, thereby effectively avoiding blockage caused by excessive quartz sand particles. After the total amount of quartz sand on the weighing tray is reduced, the pushing broom ring replenishes the quartz sand in the temporary storage ring groove back to the weighing tray, so that an appropriate amount of quartz sand is maintained on the weighing tray, effectively avoiding affecting the feeding efficiency of the quartz sand.

[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figures 1 to 4 The figure shows a feeding and dredging device for processing high-purity quartz sand, comprising a feeding hopper body 1, the interior of the feeding hopper body 1 is fixedly connected with a weighing pan 101, the upper surface of the weighing pan 101 is evenly fixedly connected with a feeding bulge 102, and the side of the feeding bulge 102 is provided with a feeding port 103 which is communicated with the lower surface of the weighing pan 101, so as to realize an L-shaped feeding port 103, and the quartz sand particles cannot fall directly like a traditional filter screen, thereby realizing the control of the feeding rate of the quartz sand particles, and the top of the feeding hopper body 1 is telescopically connected with a lifting bracket 104, the middle part of the lifting bracket 104 is fixedly connected with a rotating shaft module 105, the output end of the rotating shaft module 105 is fixedly connected with a pushing rotary frame 106, and both ends of the pushing rotary frame 106 are rotatably connected with rotating wheels 107, and a pushing broom ring 108 is movably sleeved between the two rotating wheels 107, and the pushing broom ring 108 is movably connected to the upper surface of the weighing pan 101; When feeding in the quartz sand processing process, the quartz sand added to the feed hopper body 1 first falls on the weighing plate 101, and the rotating shaft module 105 drives the pushing rotary frame 106 to rotate on the top of the weighing plate 101, and the pushing broom ring 108 is used to push the quartz sand through the drop port 103 on the side of the material bulge 102 to disperse and fall. When the rotation of the pushing rotary frame 106 is stopped or reversed, the quartz sand discharge operation is cut off in time.

[0019] Figures 3 to 7As shown, the connecting end of the weighing plate 101 and the feed hopper body 1 is fixedly connected with a temporary storage ring groove 2, which is lower than the upper surface of the weighing plate 101, and the bottom of the temporary storage ring groove 2 is lifted and connected with an annular pad 201, the upper surface of the annular pad 201 is inclined, and the lower end of the inclined surface of the annular pad 201 is parallel to the upper surface of the weighing plate 101, the bottom of the push broom ring 108 is movably connected to the upper surface of the annular pad 201, and one of the two rotating wheels 107 is fixedly connected to the drive module 2 02, the driving module 202 adopts a forward and reverse servo motor. By controlling the forward and reverse rotation of the driving module 202, the rotation direction of the pusher broom ring 108 is regulated. The bottom of one end of the pusher rotary frame 106 is fixedly connected to a broom ring supporting piece 203. The broom ring supporting piece 203 is slidably connected to the bottom of one end of the pusher broom ring 108. The pusher broom ring 108 is made of wear-resistant plastic fiber. The broom ring supporting piece 203 is used to lift one end of the pusher broom ring 108, so that the pusher broom ring 108 has only a one-way impact on the quartz sand. When the total amount of quartz sand on the weighing plate 101 is too large, the rotation direction of the pusher broom ring 108 is adjusted to rotate toward the temporary storage ring groove 2, so that the pusher broom ring 108 pushes the excess quartz sand into the temporary storage ring groove 2. At the same time, the annular pad 201 in the temporary storage ring groove 2 is adjusted up and down according to the rotation direction of the pusher broom ring 108. At this time, the annular pad 201 is in a state of downward movement, so that the internal space of the temporary storage ring groove 2 is increased, thereby accommodating more quartz sand particles. At this time, the pusher broom ring 108 still maintains the pushing effect on the quartz sand particles, so that the quartz sand is dropped through the drop port 103, thereby reducing the weighing plate 1 01, thereby effectively avoiding blockage caused by excessive quartz sand particles. After the total amount of quartz sand on the weighing tray 101 is reduced, the rotation direction of the pushing broom ring 108 is adjusted to rotate toward the center of the weighing tray 101, so that the pushing broom ring 108 replenishes the quartz sand in the temporary storage ring groove 2 back to the weighing tray 101. At this time, the annular pad 201 is in a descending state and in an ascending state, and the quartz sand is pushed out of the temporary storage ring groove 2 in an orderly manner, so that the quartz sand can return to the top of the weighing tray 101, so that an appropriate amount of quartz sand is maintained on the weighing tray 101, which effectively avoids affecting the feeding efficiency of the quartz sand.

[0020] Second implementation method: Compared with the first embodiment, the main new addition is a bulge filling block 301. The specific new structure is as follows, and the remaining structures are consistent with the first embodiment.

[0021] Figure 2 、 Figure 8 and Figure 9As shown, the bottom end of the rotating shaft module 105 is rotatably connected to the bracket 3, and the top of the bracket 3 is evenly fixedly connected to the bulge filling block 301, the bulge filling block 301 vertically corresponds to the material-passing bulge 102, and the bulge filling block 301 is plugged and corresponding to the lower opening of the blanking port 103. When the lifting bracket 104 drives the rotating shaft module 105 to move upward, it simultaneously drives the bracket 3 to move upward, so that the bulge filling block 301 blocks the blanking port 103 and cuts off the feeding supply of quartz sand. The two ends of the bottom of the bracket 3 are fixedly connected to the limiting posts 302, and the two ends of the bottom of the feed hopper body 1 are provided with limiting holes 303, and the limiting posts 302 are plugged and corresponding to the limiting holes 303. The rotation limitation of the bracket 3 is realized by plugging the limiting posts 302 and the limiting holes 303, thereby preventing the bracket 3 from rotating with the pushing and rotating rack 106. When the quartz sand processing equipment is stopped, the lifting bracket 104 drives the rotating shaft module 105 to rise, and the pushing rotary frame 106 leaves the upper surface of the weighing plate 101. The rotating shaft module 105 simultaneously drives the bracket 3 to rise. The bulge filling block 301 on the bracket 3 corresponds to the material bulge 102, so that the bulge filling block 301 blocks the lower opening of the drop port 103, thereby cutting off the falling of the remaining quartz sand on the weighing plate 101, thereby effectively improving the stability of the feed hopper body 1.

[0022] Figures 8 to 10 As shown, the interior of the bulge filling block 301 is hollow, and the top of the bulge filling block 301 is fixedly connected with a telescopic bag 4, which is made of elastic rubber material. The elasticity of the telescopic bag 4 is used to achieve buffering during the combination of the bulge filling block 301 and the blanking port 103. A hard cover 401 is fixedly embedded in the top of the telescopic bag 4, and a protruding port 402 is opened at one end of the hard cover 401. A clearing tongue piece 403 is fixedly connected to the interior of the bulge filling block 301, and the clearing tongue piece 403 passes through the protruding port 402, and the clearing tongue piece 403 Corresponding to the upper opening of the blanking opening 103, after the bulge filling block 301 is combined with the blanking opening 103, a clearing tongue piece 403 is extended outward from the extension opening 402 to clear the upper opening of the blanking opening 103. The clearing tongue piece 403 is curved in an arc shape, and the curved portion of the clearing tongue piece 403 is slidably connected to the hard cover 401. The clearing tongue piece 403 is made of spring steel material. The elasticity of the clearing tongue piece 403 is used to realize the automatic lifting of the telescopic bag 4, and the elasticity of the clearing tongue piece 403 is used to enhance the buffering capacity of the telescopic bag 4. When the bulge filling block 301 on the bracket 3 corresponds to the material bulge 102 to block the lower opening of the blanking port 103, the telescopic bag 4 on the top of the bulge filling block 301 enters and contacts the top of the blanking port 103 first, and at the same time uses the elasticity of the telescopic bag 4 to perform contact buffering, thereby effectively improving the stability of the combination of the bulge filling block 301 and the blanking port 103, and in the process of the telescopic bag 4 being flattened and deformed, the bending part of the clearing tongue piece 403 is restricted by the hard cover 401, so that the clearing tongue piece 403 is Elastic bending is performed, and the elasticity of the clearing tongue piece 403 is used to further improve the buffering capacity of the telescopic bag 4. After the bending amplitude of the clearing tongue piece 403 increases, the clearing tongue piece 403 extends outward from the extension port 402, and finally the clearing tongue piece 403 is inserted into the upper port of the blanking port 103 to achieve the unblocking of the blanking port 103. That is, when the blanking port 103 is blocked, the above operation can be performed to automatically unblock the blanking port 103, thereby effectively improving the automatic obstacle removal capability of the blanking port 103.

[0023] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
