Description

Technical Field

[0001] This invention relates to the field of quartz sand desliming technology, and in particular to a multi-stage quartz sand scrubbing device. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent, with a Mohs hardness. It is an important industrial mineral raw material, a non-hazardous chemical, and widely used in glass, casting, ceramics and fireproofing materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, filter media, and other industries.

[0003] In the production process of quartz sand, it is necessary to scrub the quartz sand to remove impurities and iron oxide adhering to the surface of the material, smooth the edges and corners of the material, achieve the effect of material purity, and improve the purity of quartz sand. However, the commonly used stirring scrubbing method has the following defects:

[0004] 1. Conventional multi-stage agitation and scrubbing desliming is an early and widespread desliming process for ores. However, its effectiveness is limited for nanoscale gangue minerals embedded in the crevices and pores of quartz surfaces. The scrubbing principle involves intense agitation of the slurry within a tank by paddles, forcing mineral particles to move at high speed. During this movement, the particles collide and rub against each other, dissociating the clay gangue particles adhering to the surface. Subsequently, based on the differences in particle size and density between the clay gangue and quartz sand, the clay gangue is removed through hydraulic classification. The desliming effect of this scrubbing machine is controlled by two factors: scrubbing time and slurry concentration. A scrubbing concentration between 50% and 60% generally yields good results; while the scrubbing time should, in principle, meet product quality requirements and should not be too long. For quartz sand ore, even under optimal conditions, the scrubbing-desliming process can only remove larger surface gangue particles. It has almost no effect on nanoscale gangue embedded in the crevices and pores of the quartz sand surface. This resulted in nearly half of the clay gangue in the quartz sand being unable to be effectively removed;

[0005] 2. Existing methods for desliming quartz sand involve agitation and scrubbing, or impacting the falling sand with water flow to separate light impurities and fine sand from the sinking large-diameter sand particles. However, the current desliming process for molding sand suffers from turbulent and disordered water flow, leading to agitation, difficulty in stabilizing the water surface, excessive air bubbles, and air content. This air is drawn into the slurry pump, causing unstable operating pressure and intermittent discharge, much like water flowing from a tap. This severely impacts the grading effect, resulting in lower product quality that fails to meet increasingly demanding process requirements. Furthermore, it poses a significant risk of cavitation and flow interruption to the slurry pump.

[0006] 3. The current method of quartz sand washing is complex and cannot achieve the desired washing effect by extending the washing time. Usually, it is simply stirred and washed before being conveyed to the next process. This reduces the effect of washing the smoothness of quartz sand particles and impurities. The washed quartz sand has a serious problem of excessive mud content, poor grading accuracy, few varieties, and unstable product quality.

[0007] Against this background, a multi-stage scrubbing device for quartz sand has practical significance and broad prospects. Summary of the Invention

[0008] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0009] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a multi-stage scrubbing device for quartz sand.

[0010] To achieve the above objectives, the technical solution of the present invention is: a multi-stage scrubbing device for quartz sand, comprising: a support base, a scrubbing and desliming mechanism, a discharge and return mechanism, and a feed pipe. Several scrubbing and desliming mechanisms are provided, each with a support base at its lower end. The several scrubbing and desliming mechanisms are arranged from high to low via the support bases. The discharge and return mechanism is installed on the side of the lowest scrubbing and desliming mechanism. Several feed pipes are provided and respectively placed on the upper end of one side of the scrubbing and desliming mechanism and the discharge and return mechanism. The discharge and return mechanism includes a return slurry pump, a collection box, a transfer pipe, a flushing chamber, a discharge chamber, a mounting plate, and a baffle. The collection box is respectively provided with a flushing chamber and a discharge chamber, which are separated by a baffle. The mounting plate is installed on the collection box, and the baffle is located at the lower end of the mounting plate. One side of the return slurry pump is connected to the flushing chamber on the collection box, and the other side is connected to the transfer pipe, which is connected to the scrubbing and desliming mechanism.

[0011] Preferably, the width of the baffle is smaller than the width of the flushing chamber, and there is a gap between the two sides of the baffle and the flushing chamber.

[0012] Preferably, the flushing chamber is located at the lower end of the feed pipe connected to the lowest scrubbing and desliming mechanism.

[0013] Preferably, the baffle is inclined at the lower end of the mounting plate, and the baffle is provided with several rows of barbed burrs.

[0014] Preferably, the scrubbing and desliming mechanism includes a jetting device and a flow stabilizing device, with several symmetrical jetting devices arranged on both sides of the upper end of the flow stabilizing device.

[0015] Preferably, the jetting device includes a jetting slurry pump, a discharge pipe, a jetting bend, and a suction pipe. The jetting slurry pump is connected to the discharge pipe, the jetting bend is connected to the discharge pipe and bends into the flow stabilizing device, and the jetting slurry pump is connected to the flow stabilizing device through the suction pipe.

[0016] Preferably, jet slurry pumps are installed on both sides of the outside of the flow stabilizing device.

[0017] Preferably, the flow stabilizing device includes a desliming box, a flow stabilizing inner frame, a material chamber, and a horizontal plate. The desliming box contains a material chamber, and the flow stabilizing inner frame is fitted into the bottom of the material chamber. The flow stabilizing inner frame is smaller than the material chamber. The material flows into the material chamber through the side wall of the flow stabilizing inner frame. One side of the material chamber is connected to the horizontal plate, and the two sides of the horizontal plate are set on the side wall of the material chamber. Several symmetrical jet bends are set on the upper two sides of the flow stabilizing inner frame. The side of the material chamber away from the flow stabilizing inner frame is connected to a discharge port, which is connected to the inlet pipe of the next scrubbing and desliming mechanism.

[0018] Preferably, a nylon layer or a PPR wear-resistant layer is provided on the side walls of both the material chamber and the flow-stabilizing inner frame.

[0019] Preferably, the device also includes a slot, through which the cross plate is detachably inserted into the material chamber, and the slot is located on the side wall of the material chamber.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are:

[0021] 1. This invention starts working with an impinging slurry pump. Under the action of the suction pipe, the impinging slurry pump draws the sand and water in the inner frame of the stable flow box out of the box, then into the discharge pipe, and finally into the scrubbing chamber from top to bottom through the impinging bend pipe. This process is repeated, so that the flow direction of the water in the chamber is not fixed. This allows the sand in the chamber to roll and rub in the water on its own, and is repeatedly impinged by the sand and water, thereby washing away the mud in the gaps or cavities on the surface of the sand. Compared with the desliming method of stirring, the friction generated by stirring can only remove surface impurities. This method can impinge all surfaces of the sand, thereby achieving efficient scrubbing and desliming of silica sand.

[0022] 2. When the sand and water in the inner frame of the present invention fill the frame, the sand and water will flow from top to bottom along the outer wall of the inner frame into the material cavity. During the flow, the activity of the sand and water in the inner frame of the stabilizing flow will be smoothed, making the flow into the material cavity more stable and playing a stabilizing role. This reduces the number of air bubbles in the sand and water in the material cavity, reduces the turbulence phenomenon, and makes the sand and water pumped by the mortar pump more even and more stable when sprayed. It effectively prevents the slurry pump from cavitation and the inability to pump out the slurry.

[0023] 3. In this invention, quartz sand and sand-water are washed by a scrubbing and desliming mechanism and then introduced into a collection box. The sand and water fall into the flushing chamber through an impact baffle, which shakes and dissipates the sludge. This process converts some of the impact force into scrubbing force between the quartz sand particles, resulting in a more thorough scrubbing. Then, the slurry pump is started to pump the material and sand-water in the flushing chamber back into the scrubbing and desliming mechanism through a transfer pipe for re-scrubbing. This achieves high-precision cyclic scrubbing. Through multiple processes and repeated cycles, the sludge in the crevices and pores on the surface of the quartz sand is kept clean. This extends the scrubbing time to achieve the desired scrubbing effect, improving the scrubbing accuracy of the grade and the quality of the scrubbing products.

Detailed Implementation

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that, as long as there is no conflict, the various embodiments and features in the various embodiments of the present invention can be combined with each other, and the resulting technical solutions are all within the protection scope of the present invention.

[0038] Furthermore, numerous specific details are set forth in the following description for illustrative purposes to provide a thorough understanding of the embodiments of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without the specific details or particular methods described herein.

[0039] Please see Figure 1 and Figure 2This invention provides a multi-stage scrubbing device for quartz sand, comprising: a support base 1, a scrubbing and desliming mechanism 2, a discharge return mechanism 3, and a feed pipe 4. Several scrubbing and desliming mechanisms 2 are provided, each with a support base 1 at its lower end. The several scrubbing and desliming mechanisms 2 are arranged from high to low via the support bases 1. The discharge return mechanism 3 is installed on one side of the lowest scrubbing and desliming mechanism 2. Several feed pipes 4 are provided and respectively placed on the upper end of one side of the scrubbing and desliming mechanism 2 and the discharge return mechanism 3. The discharge return mechanism 3 includes a return slurry pump 301 and a collection box 302. The system includes a transfer pipe 303, a flushing chamber 304, a discharge chamber 305, a mounting plate 306, and a baffle 307. The collection box 302 is provided with a flushing chamber 304 and a discharge chamber 305, which are separated by a baffle 307. The mounting plate 306 is installed on the collection box 302, and the baffle 307 is installed at the lower end of the mounting plate 306. One side of the return slurry pump 301 is connected to the flushing chamber 304 on the collection box 302, and the other side is connected to the transfer pipe 303. The transfer pipe 303 is connected to the scrubbing and desliming mechanism 2. After being stirred and scrubbed, the quartz sand material enters the scrubbing and desliming mechanism 2 through the feed pipe 4. The scrubbing and desliming mechanism 2 repeatedly jets and scrubs the material, and then guides it into the collection box 302. It falls into the flushing chamber 304 through the impact baffle 307, which has the function of converting part of the impact force into the scrubbing force between the quartz sand, making the scrubbing more thorough. Then, the return slurry pump 301 is started to pump the material and sand water in the flushing chamber 304 back into the scrubbing and desliming mechanism 2 through the transfer pipe 303 for re-jetting and scrubbing, thereby realizing high-precision cyclic scrubbing.

[0040] According to some embodiments of this application, optionally, the width of the baffle 307 is smaller than the width of the flushing chamber 304, and there is a gap between the two sides of the baffle 307 and the flushing chamber 304. The material is introduced into the flushing chamber 304 through the feed pipe 4. The return slurry pump 301 pumps back a portion of the material in the flushing chamber 304 for circulation and scrubbing. The remainder flows through the gap between the baffle 307 and the flushing chamber 304 to the discharge chamber 305 to wait for discharge. If the material carried by the return circulation and scrubbing has a lot of sludge, the material in the discharge chamber 305 is also pumped back.

[0041] According to some embodiments of this application, optionally, the flushing chamber 304 is located at the lower end of the feed pipe 4 connected to the lowest scrubbing and desliming mechanism 2. This effectively ensures that the material falling into the flushing chamber 304 has been scrubbed by multiple scrubbing and desliming mechanisms 2, resulting in more orderly scrubbing and grading and more thorough scrubbing.

[0042] Please see Figure 3The baffle 307 is inclinedly installed at the lower end of the mounting plate 306, and has several rows of reverse burrs on it. The inclination angle of the baffle 307 is 10 to 15 degrees. When the material rushes onto the baffle 307, it first collides with the baffle 307, shaking off the sludge. The material will roll from the upper end of the inclined baffle 307 to the lower end. During the rolling process, it will penetrate into the cavities of the quartz sand material in different directions through the numerous reverse burrs, thus playing a digging role and making the cavities cleaner.

[0043] Please see Figure 4 The scrubbing and desliming mechanism 2 includes a jetting device 201 and a flow stabilizing device 202. Several symmetrical jetting devices 201 are arranged on both sides of the upper end of the flow stabilizing device 202. Each jetting device 201 includes a jetting slurry pump 2011, a discharge pipe 2012, a jetting bend 2013, and a suction pipe 2014. The discharge pipe 2012 is connected to the jetting slurry pump 2011. The jetting bend 2013 is connected to the discharge pipe 2012 and bends into the flow stabilizing device 202. The jetting slurry pump 2011 is connected to the flow stabilizing device 202 through the suction pipe 2014. Sand and sand-water are introduced into the flow stabilizing device 202 through the feed pipe 4. The jet slurry pump 2011 then starts working. Under the action of the extraction pipe 2014, the jet slurry pump 2011 draws the sand and water in the flow stabilizing device 202 out of the box through the extraction pipe 2014, then into the discharge pipe 2012, and finally into the flow stabilizing device 202 from top to bottom through the jet bend pipe 2013. This process is repeated, so that the flow direction of the water in the cavity is not fixed, which can make the sand in the cavity roll in the water on its own and be repeatedly jetted by the sand and water, thereby washing away the mud in the gaps or cavities on the surface of the sand.

[0044] According to some embodiments of this application, optionally, jet slurry pumps 2011 are provided on both sides of the outer side of the flow stabilizing device 202, and the jet bends 2013 are all pointed near the center inside the flow stabilizing device 202. This serves to prevent the jetted sand and water from splashing out from the edge of the flow stabilizing device 202.

[0045] Please see Figure 5 and Figure 6Optionally, the flow stabilizing device 202 includes a desliming box 2021, a flow stabilizing inner frame 2022, a material chamber 2023, and a horizontal plate 2024. The desliming box 2021 is provided with a material chamber 2023. The flow stabilizing inner frame 2022 is fitted into the bottom of the material chamber 2023. The flow stabilizing inner frame 2022 is smaller than the material chamber 2023. The material flows into the material chamber 2023 through the side wall of the flow stabilizing inner frame 2022. One side of the material chamber 2023 is connected to the horizontal plate 2024. The two sides of the horizontal plate 2024 are provided on the side wall of the material chamber 2023. Several symmetrical jet bends 2013 are provided on the upper two sides of the flow stabilizing inner frame 2022. The side of the material chamber 2023 away from the flow stabilizing inner frame 2022 is connected to a discharge port. The discharge port is connected to the inlet pipe 4 on the next scrubbing and desliming mechanism 2. The sand and sand-water mixture is introduced into the flow stabilizing inner frame 2022 through the feed pipe 4. When the sand and water mixture fills the flow stabilizing inner frame 2022, the sand and water mixture will flow from top to bottom along the outer wall of the flow stabilizing inner frame 2023. During the flow process, the activity of the sand and water mixture in the flow stabilizing inner frame 2022 will be smoothed, making the flow into the material cavity 2023 more stable and playing a role in stabilizing the flow. This will reduce the number of air bubbles in the sand and water mixture in the material cavity 2023, reduce the phenomenon of turbulence, and thus reduce the risk of cavitation and flow interruption when the slurry pump 2011 is pumping.

[0046] According to some embodiments of this application, optionally, a nylon layer or a PPR wear-resistant layer is provided on the side walls of both the material chamber 2023 and the flow-stabilizing inner frame 2022. This provides wear resistance after contact with materials such as quartz sand and foundry sand.

[0047] According to some embodiments of this application, optionally, a slot 2025 is also included. The horizontal plate 2024 is detachably inserted into the material cavity 2023 through the slot 2025, and the slot 2025 is disposed on the side wall of the material cavity 2023. Several slots 2025 are provided on the side wall of the material cavity 2023. The horizontal plate 2024 is inserted into the slot 2025 as needed, so that the flow-stabilizing inner frame 2022 is effectively fixed inside the material cavity 2023. When removal is required, it can simply be lifted out of the slot 2025. This increases the number of installation positions for the horizontal plate 2024, increasing selectivity and applicability.

[0048] During operation, the quartz sand material first enters the mixing and scrubbing machine for initial mixing and desliming. Then, the sand and sand-water are introduced together into the stabilizing inner frame 2022 through the feed pipe 4. When the sand-water fills the stabilizing inner frame 2022, the sand-water will flow from top to bottom along the outer wall of the stabilizing inner frame 2 into the material chamber 2023. During the flow, the activity of the sand-water in the stabilizing inner frame 2022 will be smoothed, making the flow into the material chamber 2023 more stable, thus playing a stabilizing role. This reduces the number of air bubbles in the sand-water in the material chamber 2023, reducing the turbulence phenomenon, thereby reducing the risk of cavitation and flow interruption when the slurry pump 2011 is used for extraction. Then the jet slurry pump 2011 starts working. Under the action of the extraction pipe 2014, the slurry is drawn out of the box and then transferred to the discharge pipe 2012. Finally, it is jetted from top to bottom into the flow stabilizing inner frame 2022 through the jet bend pipe 2013. This process is repeated, so that the flow direction of the water in the cavity is not fixed. This allows the sand in the cavity to roll on its own in the water and be repeatedly jetted by the sand and water, thereby removing the mud from the gaps or cavities on the surface of the sand. After repeated scrubbing and desliming of the desliming mechanism 2, the material is introduced into the collection box 302 through the feed pipe 4 and falls into the flushing chamber 304 through the impact baffle 307. This process converts some of the impact force into the scrubbing force between the quartz sands, resulting in a more thorough scrubbing. Then, the return slurry pump 301 is started to pump the material and sand water in the flushing chamber 304 back into the scrubbing and desliming mechanism 2 through the transfer pipe 303 for re-flushing and scrubbing, thereby achieving high-precision cyclic scrubbing.
