Description

Technical Field

[0001] This utility model relates to the field of water washing and impurity removal technology, and in particular to a quartz sand water washing and impurity removal device. Background Technology

[0002] Quartz sand is quartz particles formed by crushing quartz stone. Quartz sand washing and impurity removal equipment is used to wash quartz sand to remove impurities. Currently, quartz sand washing and impurity removal equipment mainly includes spiral sand washing machines, wheel sand washing machines, hydrocyclones, and vibrating screen washing machines.

[0003] However, spiral sand washing machines are relatively ineffective at recovering fine-grained quartz sand, and some fine-grained quartz sand may be lost with the water flow, resulting in resource waste and reduced product recovery rate. Bucket wheel sand washing machines have a relatively small processing capacity and are generally suitable for small to medium-sized quartz sand washing operations. Hydrocyclones have strict requirements for feed pressure and concentration, requiring a dedicated feed pump and concentration regulating device to ensure stable operation. Unstable feed pressure or excessively high or low concentration will affect the grading and impurity removal effects. Vibrating screen washing machines are not effective at removing fine impurities. Utility Model Content

[0004] The purpose of this invention is to provide a quartz sand washing and impurity removal device that can separate mud and sand from quartz sand and improve the ability to remove fine impurities.

[0005] To solve the above-mentioned technical problems, the technical solution of this invention is as follows:

[0011] A spiral roller and a spray pipe are installed in the first slide at a first set angle;

[0012] The first and second draw slots are provided within the separation frame;

[0013] The first chute contains a spiral roller and a spray pipe that rub and rub the quartz sand entering from the feed inlet. The second chute performs hydraulic classification on the quartz sand and mud generated by the friction and collision. The first extraction trough collects the hydraulically classified quartz sand, and the second extraction trough collects the hydraulically classified mud.

[0014] Optionally, the horizontal distance between the first draw groove and the second slide is a second predetermined distance, and the horizontal distance between the second draw groove and the second slide is a third predetermined distance, wherein the third predetermined distance is greater than the second predetermined distance.

[0015] Optionally, the spiral roller includes two sets of rollers, the spiral blades of the two sets of rollers have opposite spiral directions, and the rotation of the two sets of rollers drives the two sets of spiral blades to rub and collide with the quartz sand.

[0016] Optionally, the distance between the two sets of spiral blades is a fourth predetermined distance.

[0017] Optionally, the spray pipe is equipped with multiple sets of nozzles, which are used to rinse the quartz sand.

[0018] Optionally, the first set slope is between 5 and 10 degrees, and the second set slope is between 20 and 35 degrees.

[0022] Optionally, the bottom of the first slide and the second slide are respectively provided with a first support frame, a second support frame and a third support frame.

[0023] The beneficial effects of this utility model are: this water washing and impurity removal device can effectively separate impurities from quartz sand through the friction and collision between the spiral roller in the first slide and the rinsing of the spray pipe. Furthermore, the subsequent hydraulic classification process in the second slide can precisely control the water flow and classification conditions, allowing fine-grained quartz sand to settle more effectively into the first extraction tank, reducing the loss of fine-grained quartz sand and improving resource utilization and product recovery rate.

[0024] The length and width of the first and second slides, as well as the rotation speed of the spiral rollers, can be adjusted to meet the needs of quartz sand washing and impurity removal at different scales. It is suitable for both small-scale production and large-scale industrial production.

[0025] Relying on the friction and collision of the spiral rollers and the rinsing and grading effect of the water flow, it is less affected by fluctuations in feed pressure and concentration, which reduces the difficulty and cost of equipment operation and improves operational stability.

[0026] In the first slide, the friction and collision of the spiral rollers can fully remove fine impurities from the surface of the quartz sand, and the flushing of the spray pipe can promptly wash away the removed fine impurities.

[0031] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figure 1 , 2 As shown in the figure, an embodiment of this utility model provides a quartz sand washing and impurity removal device, comprising:

[0033] The first slide 4 is set with a first predetermined slope;

[0034] A second slide rail 5 is set at the tail end of the first slide rail 4 with a second set slope;

[0035] A separation frame 14 is provided below the tail end of the second slide rail 5, and the vertical distance between the separation frame 14 and the second slide rail 5 is a first predetermined distance;

[0036] The inlet 1 is located at the head end of the first slide rail 4;

[0037] The spiral roller 3 and the spray pipe 2 are set at a first set angle in the first slide rail 4;

[0038] The first drawer 6 and the second drawer 7 are provided in the separation frame 14;

[0039] In this process, the spiral roller 3 and the spray pipe 2 in the first slide 4 respectively rub and collide with and wash the quartz sand entering from the feed port 1. The second slide 5 hydraulically classifies the quartz sand and mud generated by the friction and collision. The first extraction trough 6 collects the quartz sand separated by hydraulic classification, and the second extraction trough 7 collects the mud separated by hydraulic classification.

[0040] In this embodiment, the water washing and impurity removal device can effectively separate impurities from quartz sand through the friction and collision between the spiral roller 3 and the quartz sand in the first slide 4 and the rinsing of the spray pipe 2. Furthermore, the subsequent hydraulic classification process in the second slide 5 can precisely control the water flow and classification conditions, allowing fine quartz sand to settle more effectively into the first extraction tank 6, reducing the loss of fine quartz sand and improving resource utilization and product recovery rate.

[0041] The length and width of the first slide rail 4 and the second slide rail 5, as well as the rotation speed of the spiral roller 3, can be adjusted to meet the needs of quartz sand washing and impurity removal of different scales. It is suitable for both small-scale production and large-scale industrial production.

[0042] Relying on the friction and collision of the spiral roller 3 and the washing and grading effect of the water flow, it is less affected by the fluctuation of feed pressure and concentration, which reduces the difficulty and cost of equipment operation and improves the stability of operation.

[0043] In the first slide 4, the friction and collision of the spiral roller 3 can fully remove the fine impurities on the surface of the quartz sand, and the flushing of the spray pipe 2 can wash away the removed fine impurities in time. In the hydraulic classification process of the second slide 5, the fine impurities can be further separated from the quartz sand, and finally the fine impurities enter the second extraction tank 7 with the water flow, thereby effectively improving the removal capacity of fine impurities.

[0044] In an optional embodiment of this utility model, the horizontal distance between the first draw groove 6 and the second slide rail 5 is a second predetermined distance, and the horizontal distance between the second draw groove 7 and the second slide rail 5 is a third predetermined distance, wherein the third predetermined distance is greater than the second predetermined distance.

[0045] In this embodiment, during hydraulic classification in the second slide 5, quartz sand and silt, due to their different densities and particle sizes, exhibit different settling velocities and trajectories in the water flow. Quartz sand, with its higher density and faster settling, falls quickly from the end of the second slide 5 into the closer first extraction trough 6; while silt, with its lower density and slower settling, travels a greater distance under the influence of the water flow, ultimately falling into the farther second extraction trough 7. This difference in horizontal distance effectively utilizes the settling characteristics of quartz sand and silt during hydraulic classification, achieving efficient separation of the two.

[0046] By precisely setting the second and third set distances, the classification effect can be optimized based on the specific characteristics of quartz sand and silt in actual production, such as density and particle size distribution. This allows quartz sand and silt of different properties to accurately fall into their corresponding extraction tanks, reducing the mixing of quartz sand and silt, improving the accuracy of hydraulic classification, and thus enhancing the impurity removal effect and product quality of quartz sand.

[0047] Quartz sand and silt are collected into the first extraction trough 6 and the second extraction trough 7 at different horizontal distances, respectively, so that they can be processed differently in the future.

[0048] If the first collection tank 6 and the second collection tank 7 are close together, material interference may occur during the collection process. For example, mud and sand may splash into the first collection tank 6, affecting the purity of the quartz sand. By setting different horizontal distances, this mutual interference can be effectively reduced, ensuring the purity of the material in each collection tank and improving production efficiency and product quality.

[0049] In an optional embodiment of this utility model, the spiral roller 3 includes two sets of rollers 31, the spiral blades 32 of the two sets of rollers 31 having opposite spiral directions, and the rotation of the two sets of rollers 31 drives the two sets of spiral blades 32 to rub and collide with the quartz sand. The distance between the two sets of spiral blades 32 is a fourth predetermined distance.

[0050] In this embodiment, the two sets of spiral blades 32 rotate in opposite directions, generating forces on the quartz sand in different directions during rotation. When the quartz sand enters between the two sets of spiral blades 32, it is simultaneously subjected to friction and propulsion in two opposite directions. This complex force allows for more thorough friction and collision between quartz sand particles and between the quartz sand and the spiral blades 32. Compared to a single set of spiral rollers 3, this method can more effectively remove impurities adhering to the surface of the quartz sand, improving the impurity removal efficiency.

[0051] The spiral blades 32, positioned in different directions, continuously alter the trajectory of the quartz sand, causing it to repeatedly shuttle between the two sets of blades. This significantly increases the chances of the quartz sand colliding with the spiral blades 32 and other quartz sand particles. Quartz sand that might otherwise not have received sufficient friction due to its single movement path can now be effectively processed under this structure, thereby further improving the impurity removal effect.

[0052] The opposing rotation of the two sets of spiral blades 32 effectively prevents the agglomeration of quartz sand during the washing process. If a single set of spiral rollers 3 is used, the quartz sand may aggregate under the same direction, forming large particle clusters, preventing the internal quartz sand from being adequately cleaned and impurities removed. The opposing spiral blades 32, however, break up the aggregated quartz sand clusters, ensuring that each quartz sand particle is fully exposed to the water flow and the action of the spiral blades 32, improving the dispersion of the quartz sand and facilitating the separation of impurities.

[0053] With the counter-rotating helical blades 32, the quartz sand can be distributed more evenly within the first slide 4. This helps ensure the uniformity of the entire washing and impurity removal process, ensuring that each portion of the quartz sand receives the same level of treatment, avoiding localized poor impurity removal, and thus improving the stability of product quality.

[0054] The counter-rotation of the two sets of spiral blades 32 creates a complex flow pattern in the surrounding water, promoting water mixing. This mixed water flow effectively removes impurities washed away, preventing their accumulation in localized areas and improving the washing effect. Simultaneously, the thorough mixing of the water flow ensures that all the quartz sand within the first slide 4 comes into contact with fresh rinsing water, guaranteeing the quality of the cleaning process.

[0055] The fourth set distance can adjust the water flow speed to a certain extent. A suitable distance allows the water to form an appropriate flow velocity between the two sets of spiral blades 32, which can ensure that the quartz sand has enough time to stay between the blades for friction and collision, and also allows the impurities washed off to be carried away by the water flow in time, preventing the impurities from re-adhering to the surface of the quartz sand.

[0056] In an optional embodiment of this utility model, the spray pipe 2 is provided with multiple sets of nozzles, which wash the quartz sand.

[0057] In this embodiment, the multiple sets of nozzles can simultaneously wash the quartz sand at different positions on the first slide 4. Compared to a single nozzle, this covers a larger area, allowing more quartz sand to be washed at the same time, thus greatly improving washing efficiency. This means that more quartz sand can be processed per unit time, increasing the overall production capacity of the water washing and impurity removal device.

[0058] The nozzles can wash the quartz sand from different angles, thus acting on the quartz sand particles from all directions and avoiding any blind spots in the washing process. Some impurities attached to the surface depressions of the quartz sand or between the particles may not be washed away by a water flow from a single angle, but with the multi-angle nozzles, these impurities can be effectively washed away, improving the impurity removal rate.

[0059] The water jets from the nozzles have a certain impact force, which loosens impurities adhering to the surface of the quartz sand when the water flows onto it. Continuous rinsing from multiple nozzles gradually weakens the bond between impurities and the quartz sand, eventually washing them away. This rinsing method is particularly effective at separating highly viscous impurities from the quartz sand surface.

[0060] The simultaneous operation of multiple nozzles allows for the timely removal of impurities washed away, preventing them from re-depositing onto the quartz sand within the first slide 4. With only a single nozzle, some impurities might re-adhere to other quartz sand particles after washing. The water flow generated by multiple nozzles quickly removes impurities, maintaining the cleanliness of the quartz sand surface and improving the effectiveness of water washing and impurity removal.

[0061] The water jets from the nozzles not only rinse the quartz sand but also propel it, resulting in a more even distribution of the sand within the first slide rail 4. This helps prevent the quartz sand from accumulating or clustering within the slide rail, ensuring the uniformity of the subsequent friction and collision treatment by the spiral rollers 3, and further improving the effectiveness and stability of the entire washing and impurity removal process.

[0062] The spray nozzle's parameters, such as water pressure, flow rate, and angle, can be flexibly adjusted according to the impurity content and particle size of the quartz sand. For quartz sand with high impurity content or large particle size, the spray pressure and flow rate can be appropriately increased to enhance the rinsing effect. For situations where high damage to quartz sand particles is required, the nozzle angle and water flow intensity can be adjusted to reduce damage to the quartz sand while ensuring the impurity removal effect.

[0063] In an optional embodiment of this utility model, the first set slope is between 5 degrees and 10 degrees, and the second set slope is between 20 degrees and 35 degrees.

[0064] In this embodiment, the slope of the first slide 4 is between 5 and 10 degrees. The smaller slope causes the quartz sand to slide down the first slide 4 at a relatively slow speed, thereby prolonging the residence time of the quartz sand in the first slide 4. This provides more time for the spiral roller 3 to fully rub and collide with the quartz sand and for the spray pipe 2 to wash it, which helps to remove impurities from the surface of the quartz sand more effectively and improves the impurity removal effect.

[0065] This slope range ensures that the quartz sand slides smoothly downwards under gravity, preventing excessively large slopes from causing the sand to slide too quickly, resulting in material accumulation or difficulty in control; it also prevents the quartz sand from failing to slide smoothly due to insufficient slope. Stable material conveying helps ensure the continuity and stability of the entire washing and impurity removal process.

[0066] A moderate slope helps the water flow to form a stable flow state within the first slide 4, allowing the rinsing water to fully contact the quartz sand and better remove impurities. Moreover, this slope setting allows the water flow to generate appropriate scouring force on the quartz sand, enhancing the rinsing effect without causing excessive impact on the quartz sand and resulting in unnecessary wear.

[0067] The second chute 5 has an incline (between 20 and 35 degrees). A larger incline allows the quartz sand and silt to experience greater gravitational force during their descent, accelerating their movement in the water flow. Due to the differences in density and particle size between the quartz sand and silt, their settling velocities differ more significantly during this accelerated movement, thus facilitating hydraulic classification. The heavier quartz sand settles faster and falls into the first suction trough 6, while the lighter silt is carried further by the water flow and falls into the second suction trough 7, improving the accuracy and efficiency of the classification.

[0068] The relatively large incline allows quartz sand and silt to pass through the second chute 5 quickly, increasing the throughput per unit time. This is crucial for large-scale quartz sand washing and impurity removal operations, effectively improving production efficiency and meeting industrial production needs.

[0069] A steeper incline helps prevent impurities and silica sand from accumulating in the second chute 5, reducing the risk of chute blockage. Even when handling silica sand containing many impurities or with high viscosity, it ensures smooth material flow, reducing equipment malfunctions and improving operational stability and reliability.

[0070] In an optional embodiment of the present invention, a placement plate 12 is provided on the outer side of the first end of the first slide rail 4, and a stepper motor 13 for driving the spiral roller 3 is provided on the placement plate 12.

[0071] In this embodiment, the stepper motor 13 has high-precision control performance, enabling precise control of the rotational speed and direction of the spiral roller 3. By controlling the stepper motor 13, the operating parameters of the spiral roller 3 can be flexibly adjusted according to different quartz sand characteristics and impurity removal requirements, thereby achieving precise control of the degree of friction and collision of the quartz sand. For example, for quartz sand with a high impurity content, the rotational speed of the spiral roller 3 can be appropriately increased to enhance the friction and collision effect and better remove impurities; for finer-grained quartz sand, the rotational speed can be reduced to avoid excessive wear.

[0072] The placement plate 12 provides stable support for the stepper motor 13, reducing vibration and swaying during motor operation. Stable motor operation helps ensure the smooth rotation of the spiral roller 3, thereby allowing the quartz sand to undergo uniform friction, collision, and rinsing within the first slide rail 4, improving the washing and impurity removal effect and the stability of product quality. Simultaneously, reducing motor vibration also helps extend the service life of the motor and other related components, lowering equipment maintenance costs.

[0073] In an optional embodiment of the present invention, a third drawer 8 is provided inside the separating frame 14 below the first drawer 6 and the second drawer 7. The bottom of the first drawer 6 and the second drawer 7 are provided with water leakage holes, and the third drawer 8 collects the water that leaks out from the first drawer 6 and the second drawer 7.

[0074] In this embodiment, a third extraction tank 8 is used to collect water leaking from the bottom of the first extraction tank 6 and the second extraction tank 7. Although this water contains certain impurities, it can be reused in the quartz sand washing process after simple treatment (such as sedimentation and filtration), thus realizing the recycling of water resources. This not only reduces the consumption of fresh water resources and lowers production costs, but also reduces wastewater discharge.

[0075] The drainage holes at the bottom of the first extraction trough 6 and the second extraction trough 7 can promptly drain excess water from the troughs, preventing water accumulation. Water accumulation can cause the quartz sand to be soaked in water for extended periods, affecting its quality and potentially causing impurities such as mud and sand to re-mix into the quartz sand, reducing the impurity removal effect. Timely drainage ensures the dryness of the quartz sand and mud in the extraction troughs, facilitating subsequent collection and processing.

[0076] In an optional embodiment of this utility model, the feed inlet 1 is funnel-shaped. The bottoms of the first slide rail 4 and the second slide rail 5 are respectively provided with a first support frame 9, a second support frame 10, and a third support frame 11.

[0077] In this embodiment, the funnel-shaped inlet 1, wider at the top and narrower at the bottom, effectively guides the quartz sand to flow smoothly into the first chute 4 from a larger space. This prevents the quartz sand from accumulating or spilling at the inlet 1, ensuring that the material can accurately and efficiently enter the processing flow of the water washing and impurity removal device, thus improving the stability and continuity of the feeding process.

[0078] The multiple support frames provide reliable support for the first slide rail 4 and the second slide rail 5, distributing the weight and pressure borne by the slide rails. This helps maintain the shape and position stability of the slide rails, preventing them from deforming, tilting, or sinking under the weight of the quartz sand and the action of water flow, thus ensuring the long-term stable operation of the water washing and impurity removal device.

[0079] This invention achieves effective separation of impurities from quartz sand through multiple stages, including the friction and collision between the spiral roller 3 and the quartz sand, the rinsing effect of the spray pipe 2, and the hydraulic classification of the second slide 5. It not only removes surface impurities but also provides precise classification, reducing the loss of fine-grained quartz sand, improving resource utilization and product recovery rates. Furthermore, it has a strong ability to remove fine-grained impurities, thus enhancing the purity of the quartz sand and the overall product quality.

[0080] The slide length, width, and spiral roller speed can be adjusted to meet the needs of quartz sand washing and impurity removal at different scales. It is applicable to both small-scale and large-scale industrial production, increasing the versatility and flexibility of the device.

[0081] Relying on its own friction and collision, water flow washing and grading, it is less affected by the fluctuation of feed pressure and concentration, which reduces the difficulty and cost of operation. Moreover, the structural design of each part is reasonable. For example, the support frame enhances the stability of the slide, and the stepper motor 13 on the placement plate 12 ensures the stable operation of the spiral roller 3, which improves the overall operation stability and reliability of the equipment.

[0082] From the funnel-shaped design of the feed inlet 1 to ensure smooth feeding, to the setting of the extraction trough to achieve effective separation and collection of quartz sand and silt, avoiding mutual interference and facilitating subsequent different treatments, and the drainage hole and the third extraction trough 8 to achieve water resource recycling and prevent water accumulation from affecting quality, the entire material handling process is more efficient, orderly and environmentally friendly.

[0083] The stepper motor 13 can precisely control the speed and direction of the spiral roller 3. The nozzle can flexibly adjust the water spray pressure, flow rate and angle, as well as the horizontal distance between the extraction troughs and the slope of the slide, which can be set according to the actual situation. This allows the device to be precisely controlled and optimized according to the different characteristics of quartz sand and production requirements, so as to achieve the best impurity removal and grading effect.

[0084] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
