Description

Technical Field

[0001] This utility model belongs to the technical field of acid washing equipment, specifically relating to an acid washing device for purifying quartz sand. Background Technology

[0002] Quartz sand is a common mineral used in many industries. However, it often contains impurities such as iron oxides, other oxides, yellow patina, and rust. These impurities severely affect the purity and quality of the quartz sand, necessitating acid washing. Acid washing removes oxides from the quartz sand. The acid reacts with the oxides to form soluble salts, thus removing the oxides from the quartz sand. Furthermore, acid washing removes surface impurities such as yellow patina, rust, and organic pigments from the quartz sand, improving its purity and quality.

[0003] In the prior art, acid washing equipment is commonly used to purify quartz sand. For example, the invention disclosed in patent publication number CN108439416B is a quartz sand acid washing and purification device. This device includes a frame, a cylinder mounted on the upper end of the frame, a feed hopper, an air injection pump, and a stirring motor mounted on the upper end of the cylinder. The feed hopper extends into the interior of the cylinder. An air injection pipe and an air guide pipe are respectively installed at both ends of the air injection pump. A worm gear is installed at the output end of the stirring motor. A stirring shaft is mounted inside the cylinder via bearings, and a worm wheel is installed at the end of the stirring shaft. Stirring blades and air jet pipes are staggered on the outer side of the stirring shaft. A support mesh box is installed on the inner wall of the cylinder.

[0004] The aforementioned patent utilizes a stirring shaft to create a vortex in the acid solution, impacting and pickling the quartz sand. This ensures effective pickling while preventing wear between the sand and the equipment, thus avoiding secondary pollution. High-temperature gas is injected into the cylinder via an air pump, causing the quartz sand to tumble and mix thoroughly with the acid, while also heating the acid solution, improving pickling efficiency and effectiveness. However, this device uses a strainer to evenly feed the quartz sand from the rotating ring into the support cage. This feeding method requires multiple rotations of the ring, making a single feeding insufficient and time-consuming. Furthermore, since quartz sand is a solid, the support cage discharges material solely through the outlet pipe, resulting in lengthy discharge times.

[0005] Therefore, it is necessary to design an acid washing device for quartz sand purification that facilitates feeding and discharging. Utility Model Content

[0006] This invention provides an acid washing device for purifying quartz sand to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A washing device for purifying quartz sand includes: a housing component comprising a box, a mesh basket, a handle, and a valve; the top of the box is open; a protrusion is provided at the top of the box corresponding to the edge of the mesh basket; the mesh basket extends into the box and contacts the protrusion; the mesh basket is detachably connected to the box via the protrusion; the handle is located on the top surface of the mesh basket; the valve is located at the bottom of the box; and a gas supply component comprising an air pump, a first gas supply pipe, and a gas hole; the air pump is located outside the box; one end of the first gas supply pipe is connected to the output end of the air pump, and the other end extends into the box; the first gas supply pipe is located below the mesh basket; the end of the first gas supply pipe away from the air pump is a closed structure; and the gas hole is provided through the side of the first gas supply pipe facing the mesh basket.

[0009] As a further improvement to the technical solution, the first gas supply pipe includes a first pipe and a second pipe; the first pipe is distributed in parallel at intervals along the length direction of the box; both ends of the first pipe are respectively connected to the second pipe; the length direction of the second pipe is consistent with the length direction of the box; the length direction of the first pipe is consistent with the width direction of the box.

[0010] As a further improvement to the technical solution, both the first pipe and the second pipe are provided with through-holes; the vents are distributed in parallel at intervals along the length of the first pipe and the second pipe.

[0011] As a further improvement to the technical solution, the gas delivery assembly also includes a buffer tube; the buffer tube has a U-shaped structure; the first gas delivery tube is connected to the output end of the gas pump through the buffer tube; one end of the buffer tube is connected to one end of the first gas delivery tube, and the other end is connected to the output end of the gas pump.

[0012] As a further improvement to the technical solution, the housing component also includes a cover plate; the cover plate is detachably connected to the basket.

[0013] As a further improvement to the technical solution, the gas supply assembly also includes a second gas supply pipe; one end of the second gas supply pipe is connected to the end of the first gas supply pipe near the gas pump, and the other end passes through the cover plate and is connected to the interior of the basket; the second gas supply pipe is a flexible hose.

[0015] As a further improvement to the technical solution, the net baskets are distributed in parallel at intervals along the length of the box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] During the pickling process in this application, quartz sand is poured into a mesh basket, then the air pump is started, and acid solution is injected into the mesh basket or box until the acid solution covers the quartz sand. The output of the air pump delivers gas to the first gas delivery pipe. The gas flows out from the vents in the first gas delivery pipe, forming a large number of bubbles in the acid solution. The bubbles rise from the bottom of the mesh basket, move towards the basket, and burst upon contact with the basket. The bursting bubbles generate impact force, causing the acid solution to fluctuate and enhancing its flow. At the same time, a large number of bubbles rise to the top. The rising water level creates fluctuations in the water flow, resulting in greater fluctuations and stronger flow of the acid solution inside the tank. The flowing acid solution impacts the quartz sand in the basket, causing the quartz sand to tumble and ensuring full contact between the acid solution and the quartz sand for pickling. After pickling, the valve is opened to drain the acid solution, and the basket is lifted out to empty the quartz sand. The operation is convenient, allowing the quartz sand to be discharged in one go, saving time. It is also possible to pour the quartz sand into the basket in one go, effectively shortening the time required for feeding and discharging. Attached Figure Description

[0028] Example 1:

[0029] like Figures 1 to 5As shown, an acid washing device for quartz sand purification includes: a housing component 1 and a gas conveying component 2; the housing component 11 includes a box 11, a mesh basket 12, a handle 13, and a valve 14; the top of the box 11 is an open structure; a protrusion is provided at the top of the inside of the box 11 corresponding to the edge of the mesh basket 12; the mesh basket 12 extends into the inside of the box 11 and contacts the protrusion, the protrusion supports the mesh basket 12, so that the mesh basket 12 is detachably connected to the box 11; the handle 13 is provided on the top surface of the mesh basket 12 for the operator to hold the mesh basket 12; the valve 14 is provided at the bottom of the box 11. The control unit 11 controls the discharge of liquid from the housing 11; the air supply assembly 2 includes an air pump 21, a first air supply pipe 22, and an air hole 23; the air pump 21 is located outside the housing 11, preferably on the outer wall of the housing 11; one end of the first air supply pipe 22 is connected to the output end of the air pump 21, and the other end extends into the housing 11; the first air supply pipe 22 is located below the mesh basket 12; the end of the first air supply pipe 22 away from the air pump 21 is a sealed structure; the side of the first air supply pipe 22 facing the mesh basket 12 has a through air hole 23, and the air hole 23 faces the mesh basket 12. It should also be noted that the specific model of the air pump is not an improvement of this application and will not be described in detail here.

[0030] like Figure 4 and Figure 5 As shown, preferably, the first air supply pipe 22 includes a first pipe 221 and a second pipe 222; the first pipe 221 is distributed in parallel at intervals along the length direction of the box 11; both ends of the first pipe 221 are connected to the second pipe 222 respectively; the length direction of the second pipe 222 is consistent with the length direction of the box 11; the length direction of the first pipe 221 is consistent with the width direction of the box 11, so that the first air supply pipes 22 are distributed all below the basket 12; air holes 23 are opened on both the first pipe 221 and the second pipe 222; the air holes are distributed in parallel at intervals along the length direction of the first pipe 221 and the second pipe 222.

[0031] Work style:

[0032] During pickling, quartz sand is poured into the mesh basket 12, and then the air pump 21 is started. Acid solution is then injected into the mesh basket 12 or the tank 11 until the acid solution covers the quartz sand. The output of the air pump 21 supplies gas to the first gas supply pipe 22. The gas flows through the first gas supply pipe 22 and exits from the air holes 23, forming a large number of bubbles in the acid solution. These bubbles rise from the bottom of the mesh basket 12, move towards the basket, and burst upon contact with it. The bursting bubbles generate impact force, causing fluctuations in the acid solution and enhancing its flow. Simultaneously, the rising bubbles also generate water flow fluctuations, further increasing the fluctuations and flow of the acid solution within the tank 11. The flowing acid solution impacts the quartz sand inside the mesh basket 12, causing the quartz sand inside the mesh basket 12 to tumble, so that the acid solution fully contacts the quartz sand to achieve pickling. After pickling is completed, the valve 14 is opened to discharge the acid solution, and the mesh basket 12 is lifted out. Then the quartz sand inside the mesh basket 12 can be poured out. The operation is convenient, and the quartz sand can be discharged in one go, which is short. At the same time, the quartz sand can also be poured into the mesh basket 12 in one go, which effectively shortens the time spent on feeding and discharging. In addition, it should be noted that the top of the box 11 is an open end, and the mesh basket 12 does not completely cover the open end of the box 11. The gas inside the box 11 can be discharged from the open end, or an exhaust hole or other exhaust can be opened at the top of the box 11.

[0033] like Figures 2 to 5 As shown, preferably, the gas delivery assembly 2 further includes a buffer pipe 24; the buffer pipe 23 has a U-shaped structure; the first gas delivery pipe 22 is connected to the output end of the gas pump 21 through the buffer pipe 23; one end of the buffer pipe 23 is connected to one end of the first gas delivery pipe 22, and the other end is connected to the output end of the gas pump 21; the end of the buffer pipe 23 away from the gas pump 21 is connected to the second pipe 222. The buffer pipe 23 has a U-shaped structure, which can effectively prevent the acid solution in the housing 11 from flowing back into the gas pump 21 and protect the gas pump 21.

[0034] Example 2

[0035] like Figures 1 to 5As shown, compared with Embodiment 1, the difference is that: the containing component 1 also includes a cover plate 15; the cover plate 15 is detachably connected to the mesh basket 12; the gas supply component 2 also includes a second gas supply pipe 25; one end of the second gas supply pipe 25 is connected to the end of the first gas supply pipe 22 near the air pump 21, and the other end passes through the cover plate 15 and is connected to the interior of the mesh basket 12. Optionally, the second gas supply pipe 25 can be connected to the first gas supply pipe 22 through a buffer pipe 23, that is, the end of the second gas supply pipe 25 away from the cover plate 15 is connected to the buffer pipe 23; the second gas supply pipe 25 is a flexible hose to facilitate the removal and placement of the cover plate 15; after the quartz sand is acid-washed, the acid solution in the box 11 is discharged, and the air pump 21 can continue to work. The air pump 21 delivers gas to the first gas supply pipe 22 and the second gas supply pipe 25 through the buffer pipe 23 to increase the gas flow in the box 11, and at the same time sprays air into the mesh basket 12 to accelerate the drying of the quartz sand in the mesh basket 12.

[0036] like Figure 5 As shown, preferably, the gas supply assembly 2 further includes a third gas supply pipe 26; the third gas supply pipe 26 is a rigid pipe; one end of the third gas supply pipe 26 is connected to one end of the second gas supply pipe 25, and the other end extends to the bottom of the basket 12; the end of the third gas supply pipe 26 away from the cover plate 15 is a sealed structure; through-holes 23 are provided on the side of the third gas supply pipe 26, and the holes on the third gas supply pipe 26 are distributed in parallel and at intervals along the circumferential direction of the center line of the third gas supply pipe 26; during the pickling process, the cover plate 15 is pre-covered to cover the basket 12. At the open end, the third air supply pipe 26 is inserted into the mesh basket 12. The outer wall of the third air supply pipe 26 is in contact with the quartz sand. The air pump 21 also supplies air to the second air supply pipe 25 and the third air supply pipe 26. Some of the gas passes through the second air supply pipe 25 and the third air supply pipe 26 and is finally discharged from the air hole 23 of the third air supply pipe 26. The discharged gas contacts and collides with the quartz sand in the mesh basket 12, causing the quartz sand to vibrate and float, increasing the gap between the quartz sand and enhancing the fluctuation of the acid solution, expanding the contact between the quartz sand and the acid solution, and improving the pickling effect.

[0037] like Figures 1 to 5 As shown, preferably, the mesh baskets 12 are distributed in parallel at intervals along the length of the box body 11, that is, multiple mesh baskets 12 are provided, and the quartz sand is poured into multiple mesh baskets 12 respectively to evenly distribute the weight of the quartz sand, reduce the weight of the mesh baskets 12, and make it easier for operators to lift the mesh baskets 12 containing quartz sand.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
