A spiral sand washing machine for quartz sand processing

Abstract

This invention provides a spiral sand washing machine for quartz sand processing, relating to the technical field of sand washing machines. It includes a support frame with a conveying trough fixedly installed on its upper side and an extension frame fixedly installed on one side. A hopper for storing quartz sand is provided at the upper end of the extension frame. This application utilizes a support spring to support the cleaning scraper, allowing it to automatically adjust its contact pressure with the quartz sand based on its accumulation. When the cleaning scraper encounters a thick or compacted accumulation of quartz sand, the support spring contracts under pressure, applying greater pressure to ensure effective removal of impurities. Conversely, in areas with thinner or looser quartz sand, the support spring extends, reducing the scraper pressure and preventing excessive scraping that could damage the quartz sand. This ensures the scraper maintains good contact with the quartz sand, achieving a uniform cleaning effect and directly breaking down the bond between sticky impurities and the sand grain surface, overcoming the shortcomings of relying solely on water rinsing.

Description

Technical Field

[0001] This invention relates to the field of sand washing machine technology, and more specifically, to a spiral sand washing machine for quartz sand processing. Background Technology

[0002] In the production and processing of quartz sand, sand washing is a crucial step. Its purpose is to remove the mud and impurities adhering to the surface of the sand particles and improve the purity of the product. Generally, a sand washing machine is used to clean the quartz sand. Patent announcement number CN222219875U describes a spiral sand washing machine for slag treatment, which includes a spiral sand washing machine body, reinforcing blocks fixedly installed on the side wall of the spiral sand washing machine body, and processing components disposed on the side wall of the spiral sand washing machine body. The processing components include processing components installed at the bottom of the spiral sand washing machine body. A sand washing mechanism is installed on the inner wall of the spiral sand washing machine body, and the sand washing mechanism is located above the processing components. There are four reinforcing blocks, and the four reinforcing blocks are all of equal shape and size.

[0003] However, when the aforementioned sand washing machine processes quartz sand with highly adhesive mud on its surface, it mainly relies on the water flow impact generated by the agitation of the spiral blades and the basic friction between the materials to remove impurities. This relatively simple cleaning mechanism often fails to completely remove impurities with high adhesion energy, resulting in a small amount of mud remaining on the surface of the quartz sand after subsequent cleaning. To address this, this application designs a spiral sand washing machine for quartz sand processing, which gradually removes the mud from the surface of the quartz sand through segmented cleaning, thereby improving the cleaning effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a spiral sand washing machine for quartz sand processing, which solves the problem that existing sand washing machines leave some mud residue on the surface of quartz sand when cleaning quartz sand with sticky mud, resulting in poor cleaning effect.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A spiral sand washing machine for processing quartz sand includes a support frame, a conveying trough fixedly installed on the upper side of the support frame, an extension frame fixedly installed on one side of the support frame, a hopper for storing quartz sand at the upper end of the extension frame, an auxiliary component for discharging mud and water fixedly installed on one side of the conveying trough, a sand washing component for conveying and cleaning quartz sand installed inside the conveying trough, the auxiliary component including a settling trough fixedly connected to the conveying trough, a drain pipe installed on one side of the settling trough, and a water supply component installed on the upper side of the conveying trough.

[0006] Preferably, the sand washing assembly includes an extension bracket, which is fixedly installed on one side of the conveying trough. A first motor is fixedly installed inside the extension bracket. The output end of the first motor is connected to a drive spindle via a coupling. The drive spindle has helical blades fixedly installed on its shaft. Several connecting buckles are provided on the outer side of the helical blades, and a mating arc plate is installed on the outer side of the connecting buckles.

[0007] Preferably, the mating arc plate has a movable groove inside, a limiting plate is provided in the middle of the movable groove, a movable column is movably arranged inside the limiting plate, and movable seats are respectively provided at both ends of the movable column, with a cleaning scraper provided on the surface of one of the movable seats.

[0008] Preferably, the bottom of the mating arc plate is provided with a connecting bracket, which is connected to the connecting buckle. A support spring is provided on the outside of the movable column. The support spring is located between the limiting insert plate and the movable seat on the other side. A sealing soft sleeve is provided between the movable seat and the movable groove.

[0009] Preferably, the inner wall of the sinking trough is provided with two sealed bearings, one of which is connected to the drive spindle, and the other is internally connected to a passive rotating shaft. The passive rotating shaft is provided with a guide plate and an auxiliary spiral blade. A gearbox is installed on the outside of the sinking trough, with the input end of the gearbox connected to the drive spindle and the output end of the gearbox connected to the passive rotating shaft.

[0010] Preferably, a sand discharge guide plate is provided on one side of the conveying trough, and a signal slip ring is provided on one side of the expansion bracket. The rotating part of the signal slip ring is fixedly connected to the drive spindle, and the fixed part of the signal slip ring is fixedly connected to the expansion bracket. A misaligned cavity is opened on one side inside the drive spindle, and several ultrasonic generators are fixedly installed on the outside of the misaligned cavity.

[0011] Preferably, the ultrasonic generator is connected to the rotating part of the signal slip ring via a second wire, and the fixed part of the signal slip ring is equipped with a first wire.

[0012] Preferably, the drive spindle is provided with several connecting seats, and a turbulence wing is installed on the outside of the connecting seats. Several vortex holes are opened on the surface of the helical blade, and the turbulence wing is located on one side of the corresponding vortex hole.

[0013] Preferably, the water supply assembly includes a water storage tank, a water supply pump is installed at the outlet of the water storage tank, a branch pipe is installed at the outlet of the water supply pump, receiving pipes are fixedly installed on both sides of the conveying trough, the receiving pipes on both sides are connected to the branch pipes, and a plurality of spray heads are provided on the pipe body of the receiving pipes on both sides, the spray heads being inclined.

[0014] Preferably, an auxiliary guide rail is provided on the upper inner wall of the settling trough, a rotating seat is slidably installed inside the auxiliary guide rail, a filter cylinder is fixedly installed on one side of the rotating seat, a second motor is fixedly installed on one side of the settling trough, and the output end of the second motor is fixedly connected to the rotating seat. A material control valve is provided at the lower end of the material box, and a discharge conduit is installed at the lower end of the material control valve. One end of the discharge conduit extends into the inside of the filter cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a support spring, the cleaning scraper can be supported and its contact pressure with the quartz sand can be automatically adjusted according to the accumulation of quartz sand. When the cleaning scraper encounters a thick or compacted accumulation of quartz sand, the support spring is compressed and contracts, allowing the cleaning scraper to apply greater pressure to ensure effective removal of impurities. In areas where the quartz sand is thinner or looser, the support spring extends, and the pressure of the cleaning scraper is reduced accordingly to avoid excessive scraping and damage to the quartz sand. At the same time, it ensures that the cleaning scraper always maintains good contact with the quartz sand, achieving a uniform cleaning effect and directly breaking the bond between sticky impurities and the surface of the sand particles, thus solving the shortcomings of simply relying on water flushing.

[0016] 2. Several vortex holes can guide the mud and water washed from the upper layer downwards. During the guiding process, the turbulence wings set at the rear can turbulently operate on the sand material in the middle layer that requires high-intensity cleaning, actively breaking the stable laminar flow conveying state of the material inside the conveying trough, creating intense turbulence, vortices and velocity differences, thereby greatly enhancing the collision and friction between the quartz sand and the cleaning scraper, the peeling between particles and impurities, and the shearing and cleaning effect of the water flow.

[0017] 3. By starting the water supply pump, clean water inside the water storage tank is delivered to the receiving pipe through branch pipes, so that both sides can receive clean water. Then, several spray heads are used to spray the clean water, which can not only wash away the mud remaining on the surface of the spiral blades to prevent mud from adhering, but also further clean the quartz sand in contact with the cleaning scraper, reducing the mud and water remaining on the surface of the quartz sand. Together with the sand washing components, it can achieve a high-intensity sand washing operation.

[0018] 4. The material stored in the hopper can be discharged downwards and through the discharge pipe by the material control valve. The discharge pipe extends into the filter cylinder, which prevents agglomerated material from being discharged into the conveying trough in the first place. If the material is washed directly when it is agglomerated, the material inside will not be cleaned thoroughly, which is not conducive to large-scale quartz sand washing operations. By starting the second motor to drive the rotating seat to rotate, the agglomerated material inside the filter cylinder can be broken by the rotation, which helps to clean the quartz sand in the subsequent process and avoids the formation of mud clumps, which would reduce the overall cleaning effect.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 13 As shown, a spiral sand washing machine for quartz sand processing includes a support frame 1, a conveying trough 2 fixedly installed on the upper side of the support frame 1, an extension frame 101 fixedly installed on one side of the support frame 1, a material box 6 for storing quartz sand at the upper end of the extension frame 101, an auxiliary component 5 for discharging mud and water fixedly installed on one side of the conveying trough 2, a sand washing component 4 for conveying and cleaning quartz sand installed inside the conveying trough 2, the auxiliary component 5 includes a sinking trough 501, the sinking trough 501 is fixedly connected to the conveying trough 2, a sewage pipe 502 is installed on one side of the sinking trough 501, and a water supply component 3 is provided on the upper side of the conveying trough 2.

[0023] In this embodiment, the sand washing assembly 4 includes an extension bracket 401, which is fixedly installed on one side of the conveying trough 2. A first motor 4012 is fixedly installed inside the extension bracket 401. The output end of the first motor 4012 is connected to a drive spindle 402 via a coupling 406. A spiral blade 4021 is fixedly installed on the shaft of the drive spindle 402. Several connecting buckles 4023 are provided on the outside of the spiral blade 4021. A mating arc plate 403 is installed on the outside of the connecting buckles 4023.

[0024] It should be noted that the arc plate 403 has an internal movable groove 4033, and a limit plate 4038 is provided in the middle of the movable groove 4033. A movable column 4034 is movably provided inside the limit plate 4038. Movable seats 4036 are provided at both ends of the movable column 4034. A cleaning scraper 4032 is provided on the surface of one of the movable seats 4036.

[0025] Among them, the bottom of the arc plate 403 is provided with a connecting card seat 4031, which is connected to the connecting buckle 4023. A support spring 4035 is provided on the outside of the movable column 4034. The support spring 4035 is located between the limiting insert plate 4038 and the movable seat 4036 on the other side. A sealing soft sleeve 4037 is provided between the movable seat 4036 and the movable groove 4033.

[0026] During the rotation of the drive spindle 402, the spiral blades 4021 transport the quartz sand and cause several mating arc plates 403 on the outer ring to contact the quartz sand. A cleaning scraper 4032 is provided on the surface of one of the movable seats 4036, which can contact the quartz sand to actively scrub it. A sealing sleeve 4037 is provided between the movable seat 4036 and the movable groove 4033. The sealing sleeve 4037 can move and seal, ensuring that the support spring 4035 does not come into contact with the cleaning liquid, thereby improving its service life. The distribution of quartz sand inside the conveying trough 2 is not completely uniform. Its thickness and compactness vary at different locations and times. By setting a support spring 4035, the cleaning scraper 4032 can be supported and automatically adjusted according to the accumulation of quartz sand. When the cleaning scraper 4032 encounters a thicker or more compact quartz sand accumulation, the support spring 4035 is compressed and contracts, allowing the cleaning scraper 4032 to apply greater pressure to ensure effective removal of impurities. In areas where the quartz sand is thinner or looser, the support spring 4035 extends, and the pressure of the cleaning scraper 4032 decreases accordingly, avoiding excessive scraping and damage to the quartz sand. At the same time, it ensures that the cleaning scraper 4032 always maintains good contact with the quartz sand, achieving a uniform cleaning effect.

[0027] In this application, two sealed bearings 9 are provided on the inner wall of the settling tank 501. One sealed bearing 9 is connected to the drive spindle 402, and the other sealed bearing 9 is internally connected to a passive rotating shaft 503. The passive rotating shaft 503 is provided with a guide plate 504 and an auxiliary spiral blade 505. A gearbox 8 is installed on the outside of the settling tank 501. The input end of the gearbox 8 is connected to the drive spindle 402, and the output end of the gearbox 8 is connected to the passive rotating shaft 503. The drive spindle 402 is rotated by the first motor 4012. The gearbox 8 can transmit the driving power to the passive rotating shaft 503, so that the guide plate 504 and the auxiliary spiral blade 505 can rotate on the upper layer of sewage inside the settling tank 501. The guide plate 504 can actively guide the upper layer of muddy water to be discharged into the sewage pipe 502, avoiding the accumulation of sludge in the settling tank 501 and affecting the subsequent cleaning effect. The auxiliary spiral blade 505 can perform auxiliary flow guiding operation, so that the upper layer of sewage is close to the guide plate 504.

[0028] In the specific setup, a sand discharge guide plate 4011 is provided on one side of the conveying trough 2, and a signal slip ring 407 is provided on one side of the expansion bracket 401. The rotating part of the signal slip ring 407 is fixedly connected to the drive spindle 402, and the fixed part of the signal slip ring 407 is fixedly connected to the expansion bracket 401. A misaligned cavity 4024 is opened on one side inside the drive spindle 402, and several ultrasonic generators 405 are fixedly installed on the outside of the misaligned cavity 4024. The sand discharge guide plate 4011, in conjunction with the spiral blades 4021, guides the cleaned quartz sand out, realizing automatic sand washing operation.

[0029] The ultrasonic generator 405 is connected to the rotating part of the signal slip ring 407 via the second wire 4051, and the fixed part of the signal slip ring 407 is equipped with the first wire 4013.

[0030] The signal slip ring 407 is electrically connected to several ultrasonic generators 405, which are mounted on the upper drive spindle 402. This allows for further ultrasonic cleaning of the sand that has already undergone high-intensity cleaning, further removing surface mud and improving cleaning performance. The layered cleaning design employed in this application ensures sufficient cleaning intensity for the quartz sand and reduces the amount of mud adhering during cleaning, effectively improving the sand washing effect. The lower drive spindle 402, in conjunction with the spiral blades 4021, conveys the quartz sand at the bottom upwards.

[0031] It should be noted that the drive spindle 402 has several connecting seats 4041, and a turbulence wing 404 is installed on the outside of the connecting seats 4041. The surface of the spiral blade 4021 has several vortex holes 4022, and the turbulence wing 404 is located on one side of the corresponding vortex hole 4022. The vortex holes 4022 can guide the mud and water washed from the upper layer downwards. During the guiding process, the turbulence wing 404 on the rear side can perform turbulence operation on the sand material in the middle layer that requires high-intensity cleaning, actively breaking the stable laminar flow conveying state of the material in the conveying tank 2, creating intense turbulence, vortices and velocity differences, thereby greatly enhancing the collision friction between the quartz sand and the cleaning scraper 4032, the peeling between particles and impurities, and the shearing and cleaning effect of the water flow.

[0032] In this application, the water supply component 3 includes a water storage tank 301, a water supply pump 302 is installed at the outlet of the water storage tank 301, a branch pipe 303 is installed at the outlet of the water supply pump 302, receiving pipes 304 are fixedly installed on both sides of the conveying trough 2, the receiving pipes 304 on both sides are connected to the branch pipes 303, and a plurality of spray heads 305 are provided on the pipe body of the receiving pipes 304 on both sides, and the spray heads 305 are inclined.

[0033] By starting the water supply pump 302, clean water inside the water storage tank 301 is delivered to the receiving pipe 304 through the branch pipe 303, so that both sides can receive clean water. Then, the clean water is sprayed out by several spray heads 305. This not only washes away the dirt remaining on the surface of the spiral blade 4021 to prevent dirt from adhering, but also further cleans the quartz sand in contact with the cleaning scraper 4032, reducing the amount of mud and water remaining on the surface of the quartz sand. Together with the sand washing component 4, a high-intensity sand washing operation is achieved.

[0034] In this application, an auxiliary guide rail 701 is provided on the upper inner wall of the sinking trough 501, a rotating seat 702 is slidably installed inside the auxiliary guide rail 701, a filter cylinder 703 is fixedly installed on one side of the rotating seat 702, a second motor 7 is fixedly installed on one side of the sinking trough 501, and the output end of the second motor 7 is fixedly connected to the rotating seat 702. A material control valve 601 is provided at the lower end of the material box 6, and a discharge conduit 602 is installed at the lower end of the material control valve 601. One end of the discharge conduit 602 extends into the inside of the filter cylinder 703.

[0035] The material stored inside the material box 6 can be discharged downwards and through the discharge pipe 602 by the material control valve 601. The discharge pipe 602 extends into the filter cylinder 703, which prevents the agglomerated material from being discharged into the conveying trough 2 in the first place. If the material is washed directly when it is agglomerated, the material inside will not be cleaned sufficiently, which is not conducive to large-scale quartz sand washing operations. By starting the second motor 7 to drive the rotating seat 702 to rotate, the agglomerated material inside the filter cylinder 703 can be broken by the rotation, which helps to clean the quartz sand in the subsequent process and avoids the formation of mud clumps, which would reduce the overall cleaning effect.

[0036] The working principle of this spiral sand washing machine for quartz sand processing: In use, the material inside the material box 6 is first discharged into the filter cylinder 703 through the material control valve 601 for feeding. During the feeding process, the first motor 4012 is started to drive the main shaft 402 to rotate, which in turn causes the spiral blades 4021 to transport the current material to the middle layer of the conveying trough 2. During the movement, the rotation of the spiral blades 4021 causes several cleaning scrapers 4032 to contact the quartz sand and perform friction cleaning. The baffle 404 is used to enhance the cleaning intensity in the middle layer. Then the material moves to the upper layer of the conveying trough 2. During the upper cleaning process, the water supply pump 302 is activated to deliver clean water from the water storage tank 301 to the receiving pipe 304 through the branch pipe 303. Then, several spray heads 305 are used to spray clean water to remove the dirt from the surface of the quartz sand. Several ultrasonic generators 405 assist in the cleaning process. During the cleaning process, the water flows continuously downward, causing the muddy water to flow down into the settling tank 501. The muddy water is guided by the guide plate 504 to be discharged from the drain pipe 502. After cleaning, the quartz sand is discharged from the sand discharge guide plate 4011 under the action of the spiral blades 4021.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
