Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel preparation technology, and in particular to a mica separation device in manufactured sand. Background Technology
[0002] Natural rocks are hard, and when crushed, the resulting gravel and manufactured sand have poor particle shape, which can easily lead to poor workability in concrete. Furthermore, many types of rocks, especially granite, contain mica to varying degrees. The composition and content of mica often affect the water demand of concrete, making it difficult to control the concrete's condition on-site. If the mica content in the aggregate is too high, the mica will absorb water during concrete mixing, increasing the water consumption and reducing the adhesion between the aggregate and cement. When the mica content in the aggregate reaches 2%, the workability loss of the concrete is almost 50%; when the mica content reaches 10%, the slump of the concrete drops to zero. Concrete at this point is unusable due to its extremely low strength, making it very dangerous for use in building construction. Patent CN202310120063.X discloses a method for wet removal of mica from manufactured sand, including the step of first mixing materials b and a in a mixer to form a slurry. This method is relatively complex and costly. Utility Model Content

[0036] Please see Figure 1 and Figure 2This invention discloses a mica separation device for manufactured sand, comprising a support 100, a mixer 200, a container 300, and an ultrasonic component 400. The mixer 200 includes a mixing drive assembly 210, a mixing rod 220, and mixing blades 230. The mixing drive assembly 210 is mounted on the support 100 and includes a mixing motor. The upper end of the mixing rod 220 is connected to the mixing drive assembly 210, and the mixing blades 230 are connected to the lower end of the mixing rod 220. The mixing drive assembly 210 drives the mixing rod 220 to rotate. The container 300 has an internal receiving cavity 310, with an open upper end. The lower end of the mixing rod 220 extends into the receiving cavity 310, and the mixing blades 230 are located within the receiving cavity 310. The ultrasonic component 400 is mounted on the container 300 and emits ultrasonic waves into the container 300.
[0037] The ultrasonic component 400 is a common ultrasonic device in the prior art, including an ultrasonic transducer and an ultrasonic generator. The ultrasonic transducer and the ultrasonic generator are electrically connected. The ultrasonic frequency electrical oscillation signal generated by the ultrasonic generator is the power source that drives the ultrasonic transducer to work. The ultrasonic transducer converts the electrical signal into mechanical vibration and ultrasonic waves.
[0038] Manufactured sand and water are mixed and placed in the container 310 to form a turbid liquid. The stirring drive component 210 drives the stirring rod 220 to rotate, which in turn drives the stirring blades 230 to rotate. The stirring blades 230 stir the turbid liquid in the container 310, making the turbid liquid reach a high-speed and stable rotation state. Under the centrifugal force generated by the high-speed rotation, the manufactured sand particles and mica flakes can be better dispersed. During the settling process, the irregular manufactured sand particles in the solution sink faster than the flaky mica, which can achieve effective separation of the two. The ultrasonic component 400 releases ultrasonic waves into the container 300, which can further improve the dispersion efficiency of manufactured sand particles and mica flakes in the turbid liquid. After stirring is completed, the stirring drive component 210 is turned off and the mixture is kept still until no more particles continue to sink in the turbid liquid in the container 310. The liquid with mica on the top is then discharged to obtain the manufactured sand after the mica is separated. The manufactured sand mica separation device of this application is simple to operate and has a low cost.
[0039] In some embodiments, see Figure 1 and Figure 2 The container 300 is equipped with a water outlet valve 500, which has a water outlet channel that connects to the receiving cavity 310. After stirring is completed, the stirring drive component 210 is turned off and the container is allowed to stand until no more particles continue to settle in the turbid liquid in the receiving cavity 310. Then, the water outlet valve 500 is opened to discharge the upper layer of liquid containing mica, thus obtaining the machine-made sand after mica separation.
[0040] In some embodiments, see Figure 1 and Figure 2 The inner diameter of the water outlet channel ranges from 8 to 10 mm. The maximum particle size of mica particles is approximately 4.75 mm. Setting the inner diameter of the water outlet channel to 8-10 mm ensures that the mica can be discharged more quickly when the water outlet valve 500 is opened.
[0041] In some embodiments, see Figure 1 and Figure 2 Multiple outlet valves 500 are provided, spaced apart along the height. Multiple outlet valves 500 are installed on the container 300, corresponding to different heights, allowing staff to select the appropriate valve based on their needs. Depending on the amount of manufactured sand to be separated from the mica, different outlet valves 500 at different heights can be selected for drainage, making the system more versatile.
[0042] In some embodiments, see Figure 1 and Figure 2 The container 300 has a circular cross-section, and multiple water outlet valves 500 are spaced apart along the circumference of the container 300. This arrangement of multiple water outlet valves 500 along the circumference of the container 300 facilitates operation and prevents water from the upper water outlet valve 500 from splashing onto the lower water outlet valve 500. A container 300 is provided with a capacity greater than 1500ml, a graduation mark 320 ranging from 200-1000ml, and a water outlet valve 500 at the 200ml, 400ml, and 600ml positions.
[0043] In some embodiments, see Figure 1 and Figure 2 The container 300 is made of transparent material, and graduation lines 320 are set along its height. Multiple water outlet valves 500 are located near the graduation lines 320. The transparent material of the container 300 facilitates observation of changes in the turbid liquid inside. The graduation lines 320 on the container 300 facilitate the quantitative addition of the manufactured sand and water to be separated from the mica into the container 300.
[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Multiple stirring blades 230 are provided, arranged in a circular array. The stirring drive assembly 210 drives the stirring rod 220 to rotate, which in turn drives the stirring blades 230 to rotate, stirring the turbid liquid after the mixture of manufactured sand and water. The multiple stirring blades 230 improve the stirring efficiency of the mixer 200. The circular array of stirring blades 230 ensures that the centrifugal forces generated by the rotation of each stirring blade 230 can cancel each other out, preventing the stirring rod 220 from shaking during the stirring process and ensuring the stirring stability of the mixer 200.
[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The stirring blades 230 are in the shape of a propeller or a leaf. Setting the stirring blades 230 to be in the shape of a propeller or a leaf can increase the contact area between the stirring blades 230 and the turbid liquid after the mixture of manufactured sand and water, while ensuring the stirring force of the stirring blades 230, thereby improving the stirring efficiency.
[0046] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The support frame 100 includes a base 110, a support rod 120, a connecting rod 130, and a connecting clamp 140. The lower end of the support rod 120 is mounted on the base 110. One end of the connecting rod 130 is connected to the stirring drive assembly 210, and the middle part of the connecting rod 130 is movably connected to the middle part of the support rod 120 via the connecting clamp 140. When separating mica from manufactured sand, the container 300 is placed on the base 110. The base 110, support rod 120, connecting rod 130, and connecting clamp 140 are all detachable, making assembly and disassembly convenient.
[0047] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting clamp 140 includes a clamp base 141, a first clamping screw 142, and a second clamping screw 143. The clamp base 141 is provided with a first slot 1411, a second slot 1412, a first threaded hole 1413, and a second threaded hole 1414. The first threaded hole 1413 connects to the first slot 1411, and the second threaded hole 1414 connects to the second slot 1412. The support rod 120 is located within the first slot 1411. The first clamping screw 142 passes through the first threaded hole 1413 and extends into the first slot 1411. The first clamping screw 142 is threadedly connected to the first threaded hole 1413 and abuts against the support rod 120. The connecting rod 130 is located within the second slot 1412. The second clamping screw 143 passes through the second threaded hole 1414 and extends into the second slot 1412. The second clamping screw 143 is threadedly connected to the second threaded hole 1414 and abuts against the connecting rod 130. By adjusting the first clamping screw 142, the connecting clamp 140 can be easily adjusted to different positions on the support rod 120, thereby adjusting the height of the connecting rod 130 and thus adjusting the height of the mixer 200. By adjusting the second clamping screw 143, the distance between the stirring drive assembly 210 and the support rod 120 can be easily adjusted to different positions on the connecting rod 130.
[0048] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 Multiple positioning grooves 121 are provided at intervals along the length of the support rod 120, and the first clamping screw 142 extends into the positioning groove 121. The multiple positioning grooves 121 facilitate the positioning and connection of the connecting clamp 140 to the support rod 120. The groove walls of the positioning grooves 121 also provide support for the connecting clamp 140, ensuring the stable mixing of the mixer 200.
[0049] The working principle of the mica separation device in manufactured sand according to this application embodiment:
[0050] Weigh 200g of the manufactured sand containing mica to be separated and place it in container 300. Pour water into container 300 to 1000mL. Transfer container 300 to base 110. Adjust the position of mixer 200 fixed on support rod 120 using connecting clamp 140 so that the height of stirring blade 230 is at the 200mL mark. Tighten the first adjusting screw to fix mixer 200. Start the mixer 200 and ultrasonic component 400, and set the stirring speed to 600±60 r / min to make the turbid liquid (the liquid after mixing manufactured sand and water) reach a high-speed and stable rotation state. Under the centrifugal effect generated by the high-speed rotation and the ultrasonic impact of the ultrasonic component 400, the manufactured sand particles and mica flakes can be better dispersed. The stirring time is 10 min. After turning off the mixer 200 and ultrasonic component 400, let it stand for 5-10 min until no more particles continue to sink in the turbid liquid in container 300. At this time, open the water outlet valve 500 at 200 ml, so that the liquid in container 300 flows out slowly from the water outlet channel in the water outlet valve 500 until the liquid level in container 300 is level with the water outlet valve 500 at 200 ml. Then close the water outlet valve 500 at 200 ml.
[0051] Transfer container 300 to a horizontal table, transfer all the remaining liquid and manufactured sand in container 300 to a stainless steel tray, then place the stainless steel tray in an oven, adjust the temperature to 102℃, dry for 2 hours, and then weigh it to obtain the manufactured sand after separating the mica.
