Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a high-efficiency separation device for quartz sand impurities. Background Technology

[0002] In the field of quartz sand processing, quartz sand is a core raw material for high-end industries such as glass manufacturing, photovoltaic silicon wafers, electronic components, and precision casting. Its purity directly determines the quality of downstream products. Natural quartz sand ore generally contains various impurities, which need to be removed through processes such as crushing, grinding, separation, and purification. Among these processes, the impurity separation step is the key step that determines the purity of quartz sand.

[0003] In existing technologies, traditional screening devices mostly use fixed flat screens. During the screening process, materials tend to accumulate locally on the screen, causing some quartz sand particles that meet the particle size requirements to be trapped by impurities and unable to pass through the screen. Alternatively, some fine impurities may be mixed into the finished product due to screen blockage, affecting the separation accuracy. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency separation device for quartz sand impurities.

[0005] This utility model is achieved by the following technical solution: a high-efficiency separation device for quartz sand impurities, including a separation device shell, a screening component inside the separation device shell, and an auxiliary component on the left side of the screening component.

[0006] The screening assembly includes a drive motor, with a drive rod fixedly connected to the output end of the drive motor. The outer wall of the drive rod is rotatably connected to the inner wall of the separator housing. A feed inlet is provided at the top of the separator housing, and a feed pipe is connected to the top of the feed inlet. A spiral blade is fixedly connected to the outer wall of the drive rod. A screening barrel is fixedly connected to the end of the drive rod away from the drive motor. A screening plate is fixedly connected to the surface of the screening barrel. A discharge port is provided at the bottom of the separator housing. A spiral blade is fixedly connected to the surface of the screening barrel. A limit support shaft is rotatably connected to the outer wall of the screening barrel.

[0007] As a further improvement to the above solution, the left side of the drive motor is fixedly connected to the right side of the housing of the separation device, and the outer wall of the limiting support shaft is fixedly connected to the inner wall of the housing of the separation device.

[0008] As a further improvement to the above scheme, a plurality of screening plates are provided, and the plurality of screening plates are arranged symmetrically around the center of the screening barrel.

[0009] Using the above technical solution, the drive motor fixed to the right side of the separator housing is activated, and the output end of the drive motor drives the drive rod to rotate along the inner wall of the separator housing. Since the end of the drive rod away from the drive motor is fixedly connected to the screening barrel, and the outer wall of the limiting support shaft rotatably connected to the outer wall of the screening barrel is fixed to the inner wall of the separator housing, the rotation of the drive rod will drive the screening barrel to rotate synchronously, and the limiting support shaft provides stable support for the screening barrel, preventing it from shifting or shaking during rotation.

[0010] As a further improvement to the above solution, the auxiliary component includes a waste discharge trough, which is formed on the inner wall of the separator housing. An adjusting screw is threadedly connected to the inner wall of the separator housing, and an adjusting handle is fixedly connected to the left side of the adjusting screw.

[0011] As a further improvement to the above solution, a sealing disc is rotatably connected to the end of the adjusting screw away from the adjusting handle, and a connecting groove is provided on the surface of the sealing disc.

[0012] As a further improvement to the above solution, the outer wall of the adjusting screw is rotatably connected to the inner wall of the connecting groove, and the end of the sealing disc away from the adjusting screw is positioned on the left side of the screening barrel.

[0013] As a further improvement to the above solution, a receiving groove is provided on the left side of the inner wall of the waste discharge trough, and the outer wall of the sealing plate is slidably connected to the inner wall of the receiving groove.

[0014] Through the above technical solution, in the auxiliary component, the waste discharge chute is opened on the inner wall of the outer shell of the separation device, and a collection trough is opened on the left side of its inner wall. The outer wall of the sealing disc is slidably connected to the inner wall of the collection trough. In the initial state, the end of the sealing disc away from the adjusting screw is in contact with the left side of the screening barrel, forming a blockage on the left end of the screening barrel, ensuring that the impurities intercepted in the screening barrel will not fall randomly, but will gather towards the left end of the screening barrel under the propulsion of the spiral blades, preparing for the subsequent discharge of impurities.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a drive motor fixed to the right side of the separator's outer shell. The motor's output drives a drive rod to rotate along the inner wall of the separator's outer shell. Since a screening drum is fixedly connected to the end of the drive rod furthest from the drive motor, and the outer wall of the limiting support shaft, rotatably connected to the outer wall of the screening drum, is fixed to the inner wall of the separator's outer shell, the rotation of the drive rod causes the screening drum to rotate synchronously. The limiting support shaft provides stable support for the screening drum, preventing it from shifting or wobbling during rotation. The raw quartz sand to be separated is fed through the inlet at the top of the separator's outer shell. The feed pipe connected to the top of the inlet guides the material precisely into the device. Simultaneously, the spiral blades fixed to the outer wall of the drive rod rotate synchronously with the drive rod. Through the propulsive force of the spiral structure, the falling raw quartz sand is conveyed towards the screening drum, preventing material accumulation and blockage below the inlet. This ensures that the material continuously and evenly enters the screening process. The raw quartz sand inside the screening drum is moved by the rotation of the drum. Several screening plates are fixedly connected to the surface of the screening barrel, symmetrically arranged around its center. These plates have screening holes of a preset diameter. Quartz sand particles meeting the size requirements pass through these holes under the centrifugal force and gravity generated by the rotating barrel, falling to the bottom of the separator's outer shell. Impurities larger than the screening holes, such as coarse rock fragments and large clay clumps, are retained inside the barrel and cannot pass through the screening plates. Simultaneously, two spiral blades fixed to the surface of the barrel rotate with it, propelling the retained impurities towards the end of the barrel away from the drive rod, preventing accumulation and ensuring continuous screening. The pure quartz sand particles that have passed through the screening plates are finally discharged through the outlet at the bottom of the separator's outer shell, preventing localized material accumulation and ensuring effective screening of every grain of quartz sand. Furthermore, impurities larger than the screening holes are precisely retained.

[0017] In this invention, the waste discharge chute is located on the inner wall of the separator housing in the auxiliary component, and a collection groove is provided on the left side of its inner wall. The outer wall of the sealing disc is slidably connected to the inner wall of the collection groove. In the initial state, the end of the sealing disc away from the adjusting screw is in contact with the left side of the screening barrel, forming a seal on the left end of the screening barrel. This ensures that the impurities trapped in the screening barrel will not fall randomly, but will gather towards the left end of the screening barrel under the propulsion of the second spiral blade, preparing for the subsequent discharge of impurities. When a certain amount of impurities have accumulated in the screening barrel, the adjusting handle fixedly connected to the left side of the adjusting screw is rotated, causing the adjusting screw to rotate along the thread on the inner wall of the separator housing. The outer wall of the adjusting screw is rotatably connected to the inner wall of the connecting groove on the surface of the sealing disc. Because the adjusting screw is threadedly connected to the housing of the separating device, rotating the adjusting handle causes the adjusting screw to move axially, which in turn pulls the sealing disc to slide towards the inner wall of the collection tank. If it is necessary to discharge impurities, rotating the adjusting handle causes the adjusting screw to move the sealing disc away from the screening barrel, creating a gap between the left end of the screening barrel and the sealing disc. Impurities can fall into the waste discharge chute through this gap. After the impurities are discharged, rotating the adjusting handle in the opposite direction causes the adjusting screw to move the sealing disc closer to the screening barrel until the sealing disc re-contacts the left side of the screening barrel, restoring the initial sealing state. This ensures that impurities continue to accumulate in the screening barrel during subsequent screening processes, without affecting the normal screening efficiency of the screening components.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0029] The screening assembly 2 includes a drive motor 201, a drive rod 202 fixedly connected to the output end of the drive motor 201, the outer wall of the drive rod 202 rotatably connected to the inner wall of the separator housing 1, a feed inlet 203 is provided at the top of the separator housing 1, a feed pipe 204 is connected to the top of the feed inlet 203, a spiral blade 205 is fixedly connected to the outer wall of the drive rod 202, a screening barrel 206 is fixedly connected to the end of the drive rod 202 away from the drive motor 201, a screening plate 207 is fixedly connected to the surface of the screening barrel 206, a discharge port 208 is provided at the bottom of the separator housing 1, a spiral blade 209 is fixedly connected to the surface of the screening barrel 206, and a limit support shaft 210 is rotatably connected to the outer wall of the screening barrel 206.

[0030] The drive motor 201 is fixedly connected to the right side of the separator housing 1 on the left side, and the limit support shaft 210 is fixedly connected to the inner wall of the separator housing 1 on the outer wall.

[0031] Several screening plates 207 are provided, and the screening plates 207 are symmetrically arranged around the center of the screening barrel 206. The spiral blades 205 fixed on the outer wall of the drive rod 202 rotate synchronously with the drive rod 202. Through the propulsive force of the spiral structure, the falling quartz sand ore is conveyed towards the screening barrel 206, avoiding the accumulation and blockage of material below the feed inlet 203, and ensuring that the material continuously and evenly enters the screening process. The quartz sand ore inside the screening barrel 206 is driven to move with the rotation of the screening barrel 206. Several screening plates 207 are fixedly connected to the surface of the screening barrel 206 and are symmetrically arranged around the center of the screening barrel 206. Screening plates 207 are provided with screening holes of preset diameter. Quartz sand particles that meet the particle size requirements pass through the screening holes of the screening plates 207 under the action of centrifugal force and gravity generated by the rotation of the screening barrel 206 and fall into the bottom of the outer shell 1 of the separation device. Impurities with a particle size larger than the screening holes, such as coarse rock fragments and large clay clumps, are trapped inside the screening barrel 206 and cannot pass through the screening plates 207.

[0032] The auxiliary component 3 includes a waste discharge trough 301, which is located on the inner wall of the separator housing 1. An adjusting screw 302 is threadedly connected to the inner wall of the separator housing 1, and an adjusting handle 303 is fixedly connected to the left side of the adjusting screw 302.

[0033] The end of the adjusting screw 302 away from the adjusting handle 303 is rotatably connected to a sealing disc 304, and a connecting groove 305 is provided on the surface of the sealing disc 304.

[0034] The outer wall of the adjusting screw 302 is rotatably connected to the inner wall of the connecting groove 305, and the end of the sealing disc 304 away from the adjusting screw 302 is positioned on the left side of the screening barrel 206.

[0035] A receiving groove 306 is provided on the left side of the inner wall of the waste discharge trough 301. The outer wall of the sealing disc 304 is slidably connected to the inner wall of the receiving groove 306. By rotating the adjusting handle 303 fixedly connected to the left side of the adjusting screw 302, the adjusting screw 302 is driven to rotate along the thread on the inner wall of the separator housing 1. The outer wall of the adjusting screw 302 is rotatably connected to the inner wall of the connecting groove 305 opened on the surface of the sealing disc 304. Since the adjusting screw 302 is threadedly connected to the separator housing 1, when the adjusting handle 303 is rotated, the adjusting screw 302 will move axially, thereby pulling the sealing disc 304 to slide towards the inner wall of the receiving groove 306.

[0036] The implementation principle of the high-efficiency quartz sand impurity separation device in this application embodiment is as follows: By starting the drive motor 201 fixed on the right side of the separator housing 1, the output end of the drive motor 201 drives the drive rod 202 to rotate along the inner wall of the separator housing 1. Since the end of the drive rod 202 away from the drive motor 201 is fixedly connected to the screening barrel 206, and the outer wall of the limiting support shaft 210 rotatably connected to the outer wall of the screening barrel 206 is fixed to the inner wall of the separator housing 1, the rotation of the drive rod 201 will drive the screening barrel 206 to rotate synchronously. The limiting support shaft 210 provides stable support for the screening barrel 206, preventing it from deviating or shaking during rotation. The raw quartz sand ore to be separated is fed into the feed port 203 opened at the top of the separator housing 1. The feed pipe 204 connected to the top of the feed port 203 can guide the material to fall accurately into the device. Simultaneously, the spiral blades 205 fixed to the outer wall of the drive rod 202 rotate synchronously with the drive rod 202. Through the propulsive force of the spiral structure, the falling quartz sand ore is conveyed towards the screening barrel 206, preventing material from accumulating and clogging below the feed inlet 203, ensuring that the material continuously and evenly enters the screening process. The quartz sand ore inside the screening barrel 206 is driven to move with the rotation of the screening barrel 206. Several screening plates 207 are fixedly connected to the surface of the screening barrel 206, symmetrically arranged around the center of the screening barrel 206. Screening plates 207 have screening holes with a preset aperture. Quartz sand particles that meet the particle size requirements pass through the screening holes of the screening plates 207 under the action of centrifugal force and gravity generated by the rotation of the screening barrel 206 and fall into the bottom of the outer shell 1 of the separation device. Impurities larger than the screening holes, such as coarse rock fragments and large clay lumps, are trapped inside the screening barrel 206 and cannot pass through the screening plates. 207. Simultaneously, the spiral blades 209 fixed on the surface of the screening barrel 206 rotate with the screening barrel 206, generating a propulsive force on the trapped impurities, conveying them to the end of the screening barrel 206 away from the drive rod 202, preventing impurities from accumulating inside the screening barrel 206, ensuring continuous screening. Pure quartz sand particles passing through the screening plate 207 are finally discharged through the discharge port 208 opened at the bottom of the separator housing 1, avoiding local accumulation of materials and ensuring that each grain of quartz sand is effectively screened. At the same time, impurities larger than the screening holes will be accurately trapped.Furthermore, in auxiliary component 3, waste discharge trough 301 is opened on the inner wall of the outer shell 1 of the separation device, and a collection trough 306 is opened on the left side of its inner wall. The outer wall of the sealing plate 304 is slidably connected to the inner wall of the collection trough 306. In the initial state, the end of the sealing plate 304 away from the adjusting screw 302 is in contact with the left side of the screening barrel 206, forming a blockage on the left end of the screening barrel 206, ensuring that the impurities trapped in the screening barrel 206 will not fall randomly, but will gather towards the left end of the screening barrel 206 under the propulsion of the spiral blade 209, preparing for the subsequent discharge of impurities. When a certain amount of impurities accumulate in the screening barrel 206, the adjusting handle 303 fixedly connected to the left side of the adjusting screw 302 is rotated, which drives the adjusting screw 302 to rotate along the thread of the inner wall of the outer shell 1 of the separation device. The outer wall of the adjusting screw 302 is rotatably connected to the inner wall of the connecting groove 305 opened on the surface of the sealing plate 304. Since the adjusting screw 302 is threadedly connected to the outer shell 1 of the separating device, when the adjusting handle 303 is rotated, the adjusting screw 302 will move axially, thereby pulling the sealing plate 304 to slide towards the inner wall of the receiving trough 306. If it is necessary to discharge impurities, by rotating the adjusting handle 303, the adjusting screw 302 will drive the sealing plate 304 to move away from the screening barrel 206, so that a gap is formed between the left end of the screening barrel 206 and the sealing plate 304. Impurities can fall into the waste discharge trough 301 through this gap. After the impurities are discharged, the adjusting handle 303 is rotated in the opposite direction, and the adjusting screw 302 will drive the sealing plate 304 to move closer to the screening barrel 206 until the sealing plate 304 re-contacts the left side of the screening barrel 206, restoring the initial sealing state, ensuring that impurities continue to accumulate in the screening barrel 206 during subsequent screening processes, without affecting the normal screening efficiency of the screening component 2.
