Utilizing electromagnetic principles, these separators adsorb iron particles from the silica sand during transport, thus achieving iron removal. However, the operation of electromagnetic separators consumes a large amount of electrical energy, leading to energy waste. Furthermore, the electromagnetic separators can only adsorb iron particles on the surface of the silica sand; iron particles remain inside the sand, resulting in low efficiency and quality of iron removal.

[0026] The iron removal assembly of a first aspect embodiment and the silicon sand iron removal device of a second aspect embodiment of the present invention will now be described with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, in the embodiments of the present invention, the up-down direction is indicated as the first direction, and the left-right direction is indicated as the second direction.

[0027] A first aspect of the present invention provides an iron removal component 100 for adsorbing iron substances, see below. Figures 1 to 3 As shown, the iron removal assembly 100 includes a fixed base 110 and multiple adsorption elements 120. The fixed base 110 serves as the mounting carrier for the iron removal assembly 100. The fixed base 110 has a connected support member 111 and a connecting member 112. The connecting member 112 is provided with multiple mounting holes 113, which are spaced apart from each other. The multiple adsorption elements 120 are connected to the connecting member 112 and are installed in different mounting holes 113, also spaced apart from each other. The adsorption elements 120 are magnetic components used to adsorb iron substances in silica sand.

[0028] Specifically, in one example, the purified silica sand is stored in a warehouse awaiting batching. When the silica sand needs to be used, it is transported via conveyor components 300 such as belt conveyors and bucket elevators. During warehouse storage and transportation, the silica sand may be contaminated with iron; therefore, this embodiment selects to perform iron removal on the silica sand during transportation.

[0029] When the iron removal assembly 100 is in use, it is installed downstream of the conveying assembly 300, at the outlet of the silica sand conveying. Adsorption elements 120 are positioned opposite the outlet of the conveying assembly 300 and installed along the silica sand conveying path, ensuring the silica sand comes into contact with them before being used. Because the multiple adsorption elements 120 are spaced apart, when the silica sand and the adsorption elements 120 come into contact, the silica sand is cut by the adsorption elements 120 and passes through the gaps between them to pass through the iron removal assembly 100. This causes iron particles inside and outside the silica sand to be magnetically adsorbed onto the adsorption elements 120, thereby achieving iron removal from the silica sand, increasing the adsorption rate of iron particles, and improving the efficiency and quality of the iron removal operation.

[0030] In related technologies, the operation of electromagnetic separators requires a large amount of electrical energy, resulting in energy waste. Furthermore, since silica sand is stacked during transportation to form a thick structure, when the electromagnetic separator adsorbs iron in the silica sand, it can only adsorb iron on the surface of the silica sand, while iron remains inside the silica sand, resulting in incomplete adsorption of iron.

[0031] Compared to related technologies, the iron removal assembly 100 of this invention is positioned downstream of the conveying assembly 300 that conveys silica sand. This allows the silica sand to fall into the assembly 100 after conveying, where it is cut by the adsorption members 120, causing it to fall through the gaps between the adsorption members 120. As the silica sand passes through the adsorption members 120, magnetic impurities within it are magnetically attracted to the adsorption members 120, thus effectively removing these impurities. Furthermore, the iron removal assembly 100 of this application does not require electricity, saving energy and reducing consumption.

[0032] In some embodiments, see Figure 2 and Figure 3 As shown, the connector 112 also includes a mounting chamber 1121 and a fixing plate 1125. The fixing plate 1125 is connected to the support member 111. The interior of the mounting chamber 1121 defines a mounting cavity 1124. The support member 111 and the fixing plate 1125 jointly support the mounting chamber 1121. A mounting hole 113 is provided on the inner wall of the mounting chamber 1121, and the mounting hole 113 and the mounting cavity 1124 are interconnected. The adsorption member 120 is disposed in the mounting cavity 1124.

[0033] Specifically, the mounting chamber 1121 defines a cavity for mounting the adsorbent 120 and for supplying silica sand. A mounting hole 113 is provided on the cavity of the mounting chamber 1121. When the adsorbent 120 and the connector 112 are assembled, the adsorbent 120 enters the mounting cavity 1124 through the mounting hole 113 and is fixedly connected to the mounting chamber 1121. Multiple adsorbents 120 divide the mounting cavity 1124, forming multiple channels for silica sand flow within the mounting chamber 1121, with the adsorbents 120 forming the walls of these channels. By placing the adsorbents 120 within the mounting cavity 1124, the cavity of the mounting cavity 1124 limits the flow of silica sand after it enters, thus preventing deviation during flow and improving the concentration of the silica sand while reducing spillage. Furthermore, the adsorption element 120 divides the mounting cavity 1124 to form multiple channels, which increases the contact area between the silica sand and the adsorption element 120 when the silica sand enters the mounting cavity 1124 for impurity removal, thereby further improving the adsorption efficiency of the adsorption element 120 and promoting the removal quality of iron impurities.

[0034] Further, see Figure 2 and Figure 3 As shown, the mounting chamber 1121 has a first hole group 1131 and a second hole group 1132 spaced apart along the vertical direction. Both the first hole group 1131 and the second hole group 1132 are formed by multiple mounting holes 113 spaced apart along the horizontal direction. There is a gap between adjacent mounting holes 113 in the first hole group 1131, and there is also a gap between adjacent mounting holes 113 in the second hole group 1132; this gap is defined as the hole spacing. The hole spacing of the first hole group 1131 and the hole spacing of the second hole group 1132 are alternately arranged along the horizontal direction.

[0035] Specifically, the hole spacing of the first hole group 1131 and the hole spacing of the second hole group 1132 do not have corresponding portions in the vertical direction. That is, from the vertical direction, the mounting holes 113 of the first hole group 1131 and the hole spacing of the second hole group 1132 correspond to each other, and the mounting holes 113 of the first hole group 1131 can be inserted into the hole spacing of the second hole group 1132. In this way, by making the hole spacing of the first hole group 1131 and the second hole group 1132 alternate from the left and right direction, after the adsorbent 120 is installed in the mounting hole 113, the adsorbent 120 installed in the first hole group 1131 and the adsorbent 120 installed in the second hole group 1132 are also alternately arranged in the left and right direction. This ensures that the adsorbent 120 at the first hole group 1131 will not block the adsorbent 120 at the second hole group 1132 from the vertical direction. When the silica sand enters the mounting cavity 1124 from the conveying assembly 300 and comes into contact with the adsorption element 120 to perform iron removal, the adsorption element 120 at the first hole group 1131 and the adsorption element 120 at the second hole group 1132 will not block each other, thereby allowing the silica sand to come into contact with multiple adsorption elements 120, which further improves the impurity removal efficiency of the silica sand.

[0036] Further reading Figure 2 and Figure 3 As shown, the fixing plate 1125 and the connector 112 are circumferentially arranged on the outer wall of the mounting chamber 1121. The mounting chamber 1121 has a first part 1122 and a second part 1123. A first hole group 1131 and a second hole group 1132 are provided on both the first part 1122 and the second part 1123. The first part 1122 and the second part 1123 of the mounting chamber 1121 are symmetrically arranged about the fixing plate 1125.

[0037] Specifically, the fixing plate 1125 and the connector 112 are installed on the outer periphery of the installation chamber 1121, so that after the adsorption component 120 is installed in the installation chamber 1121, the fixing plate 1125 and the connector 112 can provide support and fixation for the installation chamber 1121, thereby improving the stability of the adsorption component 120 and the installation chamber 1121 in use. Furthermore, the first part 1122 and the second part 1123 are the upper and lower parts of the installation chamber 1121, and the first part 1122 and the second part 1123 are symmetrically arranged about the fixing plate 1125, that is, the upper and lower parts of the installation chamber 1121 have the same structure, and the fixing plate 1125 separates the installation chamber 1121. When the adsorption element 120 is assembled on the first part 1122 and the second part 1123, the adsorption elements 120 are positioned and numbered identically in both parts. This ensures that after the silica sand enters the mounting cavity 1124 from the conveying assembly 300, it flows vertically along the mounting chamber 1121 and undergoes two impurity removal processes. When the silica sand passes through the first part 1122, the adsorption element 120 in the first part 1122 performs a first impurity removal process to initially adsorb iron substances from the silica sand. Then, the silica sand flows through the section connecting the fixing plate 1125 and the mounting chamber 1121, where no impurity removal is performed to buffer the flow of the silica sand. The silica sand then enters the second part 1123 to contact the adsorption element 120, thereby achieving a second impurity removal process. These two impurity removal processes increase the adsorption rate of iron substances, thus improving the efficiency and quality of iron removal from the silica sand.

[0038] In some embodiments, see Figure 4 As shown, the iron removal assembly 100 also includes a chute 130, which is connected to the mounting chamber 1121 and is positioned on the side of the mounting chamber 1121 facing the conveying assembly 300 along the conveying direction of the silica sand. The chute 130 is inclined relative to the mounting chamber 1121, creating an angle between the chute 130 and the mounting chamber 1121. Specifically, the chute 130 is positioned between the mounting chamber 1121 and the conveying assembly 300 along the conveying direction of the silica sand. When the silica sand is conveyed to the iron removal assembly 100 by the conveying assembly 300, the chute 130 receives the silica sand. The silica sand moves onto the chute 130 and is guided by the chute 130 into the mounting cavity 1124 of the mounting chamber 1121. Furthermore, in this embodiment, since the chute 130 is inclined, the silica sand will slide along the inclined path of the chute 130 after it moves to the chute 130, thereby improving the conveying efficiency of the silica sand and promoting the iron removal efficiency of the iron removal component 100.

[0039] In some embodiments, see Figure 3As shown, the adsorption members 120 are spaced apart in the mounting holes 113 of the connector 112 along the length direction of the connector 112. However, the adsorption members 120 are not completely contained within the mounting holes 113; at least a portion of the adsorption members 120 extends out of the mounting holes 113. That is, after the adsorption members 120 are installed in the mounting holes 113, the ends of the adsorption members 120 extend out of the mounting holes 113.

[0040] Specifically, in one example, the adsorption element 120 is a cylindrical or rod-shaped permanent magnet (such as a neodymium iron boron magnet). When the adsorption element 120 and the connector 112 are assembled, the adsorption element 120 is inserted into the corresponding mounting hole 113 from one side of the connector 112 and protrudes from the other side of the connector 112. Multiple adsorption elements 120 are arranged parallel and spaced apart. When silica sand falls from the end of the conveying assembly 300, the silica sand passes through the gaps between the adsorption elements 120, causing the iron in the silica sand to be adsorbed. Extending a portion of the adsorption element 120 out of the mounting hole 113 prevents the adsorption element 120 from being buried by a large amount of silica sand after it enters the iron removal assembly 100 and comes into contact with it, thus preventing a weakening of its magnetism. This ensures the adsorption performance of the adsorption element 120. Furthermore, when the silica sand enters the iron removal component 100, it will have a certain initial velocity driven by the conveying component 300. By exposing part of the adsorption element 120 outside the mounting hole 113, the adsorption element 120 can adsorb the silica sand that deviates during the falling process, thus preventing iron from entering the batching process from the outside of the iron removal component 100, thereby improving the iron removal efficiency of the silica sand.

[0041] A second aspect of the present invention provides a silica sand iron removal device 10, see reference. Figures 1 to 4 As shown, the silica sand iron removal device 10 includes a base 200, a conveying assembly 300, and an iron removal assembly 100 as described in any of the above embodiments. The base 200 is used to assemble the conveying assembly 300 and the iron removal assembly 100. The conveying assembly 300 is connected to the base 200 and can be a belt conveyor, bucket elevator, screw conveyor, or other equipment suitable for conveying silica sand. In actual production, purified silica sand is usually stored in a warehouse. When it needs to be used for batching, the silica sand is conveyed from the warehouse through the conveying assembly 300 for batching.

[0042] Specifically, in one example, a magnetic stripe assembly 100 is installed downstream of the conveying assembly 300, at the outlet end of the silica sand conveying path. The support member 111 of the magnetic stripe assembly 100 is fixedly connected to the base 200, thus installing the entire magnetic stripe assembly 100 downstream of the conveying outlet. Multiple adsorbents 120 in the magnetic stripe assembly 100 are arranged at intervals along the silica sand falling path, and the adsorbents 120 face the discharge port of the conveying assembly 300. When the silica sand falls from the conveying assembly 300, it passes through the gaps between the adsorbents 120. Because the adsorbents 120 are magnetic, during the process of the silica sand being cut and passing through the gaps between the adsorbents 120, the ferromagnetic impurities contained in the silica sand are adsorbed onto the surface of the adsorbents 120 by the magnetic force, while the pure silica sand is unaffected by the magnetic force and thus passes through the gaps into the downstream batching process.

[0043] In related technologies, electromagnetic separators need to be installed on belt conveyors, which causes the belt conveyor to be under pressure from the battery separator, thus affecting the conveying efficiency of silica sand. Compared with related technologies, the silica sand iron removal device 10 of this invention uses an iron removal component 100 located downstream of the conveying component 300 to cut and adsorb the conveyed silica sand, thereby increasing the adsorption rate of iron and improving the efficiency and quality of iron removal.

[0044] In some embodiments, see Figure 4 As shown, the iron removal assembly 100 and the conveying assembly 300 are spaced apart along the conveying direction of the silica sand. Specifically, since the silica sand moves under the drive of the conveying assembly 300, after the silica sand separates from the conveying assembly 300, it will continue to move forward under inertia. By maintaining a gap between the iron removal assembly 100 and the conveying assembly 300, the accuracy of the silica sand entering the iron removal assembly 100 can be improved. Simultaneously, the spaced arrangement of the iron removal assembly 100 and the conveying assembly 300 provides the silica sand with sufficient falling space before entering the iron removal assembly 100, thereby promoting uniform dispersion of the silica sand. Furthermore, the spaced arrangement of the iron removal assembly 100 and the conveying assembly 300 can prevent equipment vibration, material impact, or structural interference during the silica sand conveying process from affecting the iron removal assembly 100 and causing a decrease in iron removal efficiency.

[0045] In another embodiment, see Figure 4 As shown, the base 200 has an opening 210, which is spaced apart from the iron removal component 100 along the vertical direction. Specifically, the bottom of the base 200 has an opening 210 for conducting silica sand, which is spaced apart from the iron removal component 100 along the vertical direction. After the silica sand is cut by the adsorption member 120 to adsorb the iron in the silica sand, the silica sand will flow out from the bottom of the fixed seat 110 and be guided through the opening 210 to enter the next process.

[0046] The opening 210 and the iron removal component 100 are spaced apart, allowing the silica sand to be continuously discharged after impurity removal, thus preventing silica sand from accumulating between the outlet of the iron removal component 100 and the opening 210 of the base 200. Furthermore, since the silica sand is accompanied by dust during its descent, the silica sand passes through the spaced section between the iron removal component 100 and the opening 210, preventing dust accumulation inside the iron removal component 100 and thus avoiding dust adhering to the surface of the adsorption element 120, thereby improving the adsorption effect of the adsorption element 120.

[0047] Furthermore, in one example, see [link to example]. Figure 4 As shown, the connector 112 defines a receiving cavity, which is the cavity formed by the mounting chamber 1121. A mounting hole 113 is provided on the cavity wall of the mounting cavity 1124, and the mounting hole 113 communicates with the mounting cavity 1124. The adsorption member 120 is housed in the mounting cavity 1124. The mounting cavity 1124 and the opening 210 correspond vertically, and the connector 112 partially blocks the opening 210 vertically. Specifically, the mounting cavity 1124 connects the upper and lower sides of the connector 112, making the connector 112 a hollow structure, and the adsorption member 120 is disposed inside the connector 112. When the silica sand moves to the iron removal assembly 100, the silica sand enters the mounting cavity 1124 from the upper end of the connector 112 to contact the adsorption member 120. After the silica sand completes its adsorption operation, it is discharged from the lower end of the connector 112. This vertical correspondence between the mounting cavity 1124 and the opening 210 improves the accuracy of silica sand discharge and reduces the possibility of silica sand spillage. Furthermore, the size of the opening 210 is larger than the size of the mounting cavity 1124, which causes the connector 112 to partially block the opening 210, thereby further improving the stability of the silica sand being introduced from the mounting cavity 1124 into the opening 210.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
