Description

Technical Field

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

[0002] Quartz is a non-metallic mineral characterized by its hardness, wear resistance, and chemical stability. Quartz sand is produced by crushing quartz into particles. However, quartz contains iron impurities, and the crushed quartz sand also contains iron impurities. If these iron impurities are not removed, the purity and quality of the quartz sand will be severely reduced. Therefore, iron impurities need to be removed during quartz sand production.

[0003] In the prior art, iron removal devices are usually used to remove iron impurities from quartz sand. For example, the utility model with patent publication number CN220126903U discloses an iron removal device for quartz sand. The device includes a mounting frame and a fixed bucket. Two limiting wheels are provided on the side of the mounting frame near the fixed bucket. A side plate is fixedly connected to the front end of the lower surface of the mounting frame. A servo motor is fixedly connected to the outer wall of the front end of the side plate. The output end of the servo motor passes through the side plate and is fixedly connected to a drive gear.

[0004] The aforementioned iron removal device uses magnets to remove iron from quartz sand. However, the iron impurities attracted by the magnets remain attached to the magnets, occupying their surface and accumulating over time. This increases the magnet's thickness, resulting in the presence of non-magnetic iron impurities during magnet adsorption, thus reducing the magnet's magnetic attraction to iron impurities. Although the device allows workers to remove the magnets from their placement slots by pulling out the mounting plate for cleaning, the magnets' magnetic force is long-lasting, and the iron impurities cannot be separated from the magnets, leading to lengthy cleaning times and extended machine downtime.

[0005] Therefore, it is necessary to design an iron removal device for quartz sand production that can quickly separate iron impurities from magnets in order to shorten machine downtime. Utility Model Content

[0006] This invention provides an iron removal device for quartz sand production 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] An iron removal device for quartz sand production includes: a conveying assembly comprising a belt conveyor and a first housing; the belt conveyor is horizontally positioned; the top of the first housing is open; the first housing is located directly below one end of the belt conveyor; the iron removal assembly includes a support, a linear motion mechanism, an electromagnet, and a controller; the support is located in the middle of the belt conveyor; the top of the support is directly above the belt conveyor; the electromagnet is mounted on the support and located directly above the conveying area of ​​the belt conveyor; the linear motion mechanism is mounted on the support and its orientation is the same as the width direction of the belt conveyor; the movable end of the linear motion mechanism is connected to the electromagnet; the controller is electrically connected to the electromagnet and the linear motion mechanism.

[0009] As a further improvement to the technical solution, the electromagnet is made of soft magnetic material.

[0010] As a further improvement to the technical solution, the bracket includes a gantry frame, a support plate, and a slider; the gantry frame is distributed in parallel at intervals along the length direction of the belt conveyor; the support plate is disposed on the top of the gantry frame; a slot is formed on the support plate along the width direction of the belt conveyor; the linear motion mechanism is connected to the electromagnet through the slider; one end of the electromagnet extends into the slot and is connected to the slider; the linear motion mechanism is disposed on the support plate; the movable end of the linear motion mechanism is connected to the slider.

[0011] As a further improvement to the technical solution, the bracket also includes a pulley; the pulley is rotatably mounted on the bottom surface of the slider; the slider moves along the length direction of the slot.

[0012] As a further improvement to the technical solution, the length of the portal frame is greater than the width of the electromagnet and the belt conveyor.

[0013] As a further improvement to the technical solution, the iron removal assembly also includes a second housing; the second housing is located on one side of the belt conveyor corresponding to the electromagnet; the top of the second housing is an open end; the second housing is located directly below the slot.

[0014] As a further improvement to the technical solution, the conveying assembly also includes a hopper; the hopper is located at the end of the belt conveyor away from the first housing; the discharge end of the hopper faces the conveying area of ​​the belt conveyor.

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

[0016] In this application, the belt conveyor and electromagnet are started. Quartz sand is added to the end of the belt conveyor furthest from the first housing. The quartz sand moves towards the first housing with the belt conveyor. During this movement, the quartz sand passes the electromagnet, which generates a magnetic attraction force, attracting iron impurities in the quartz sand to achieve iron removal. After iron removal, the quartz sand moves towards the first housing and finally falls into it. When the electromagnet is full of iron impurities, quartz sand is temporarily added to the belt conveyor or the belt conveyor is stopped, and a linear conveyor is started via the controller. The linear motion mechanism drives the electromagnet to move towards one side of the belt conveyor, moving it away from the conveying area. Then, the controller de-energizes the electromagnet, eliminating its magnetic force. After the electromagnet is demagnetized, the iron impurities fall off due to gravity and separate from the electromagnet. The linear motion mechanism then drives the electromagnet to reset, and the quartz sand is cleaned again to remove iron, thus completing the separation of iron impurities from the magnet. By utilizing the changing magnetic attraction of the electromagnet and the characteristics of soft magnetic materials that are easy to magnetize and demagnetize, the downtime of the entire device is effectively reduced.

[0026] Example 1:

[0027] like Figures 1 to 4As shown, an iron removal device for quartz sand production includes a conveying assembly 1 and an iron removal assembly 2. The conveying assembly 1 includes a belt conveyor 11 and a first housing 12. The belt conveyor 11 is horizontally positioned. The top of the first housing 12 is open. The first housing 12 is located directly below one end of the belt conveyor 11 to receive the quartz sand conveyed by the belt conveyor 11. The iron removal assembly 2 includes a support 21, a linear motion mechanism 22, an electromagnet 23, and a controller. The support 21 is located in the middle of the belt conveyor 11. The top of the support 21 is directly above the belt conveyor 11. The electromagnet 23 is mounted on the support 21 and is located directly above the conveying area of ​​the belt conveyor 11. The linear motion mechanism 22... Mechanism 22 is mounted on support 21, with its orientation aligned with the width direction of belt conveyor 11. Mechanism 22 can be a hydraulic rod, cylinder, electric push rod, or lead screw slide, etc. The movable end of mechanism 22 is connected to electromagnet 23, causing electromagnet 23 to move towards one side of belt conveyor 11. A controller is electrically connected to electromagnet 23 and mechanism 22, controlling both. The controller can be mounted on support 21, and its position is not limited. Preferably, electromagnet 23 is made of soft magnetic material, such as iron-silicon alloy or iron-aluminum alloy. Soft magnetic materials are easily magnetized and demagnetized, quickly acquiring and quickly eliminating magnetic attraction. It should be noted that the connection between the controller and the electromagnet and linear movement mechanism is a conventional connection; the specific models of the controller and linear movement mechanism are not improvements of this application and will not be elaborated upon here.

[0028] Work style:

[0029] In operation, the belt conveyor 11 and electromagnet 23 are started. Quartz sand is added to the end of the belt conveyor 11 furthest from the first housing 12. The quartz sand moves towards the first housing 12 along with the belt conveyor 11. During this movement, the quartz sand passes the electromagnet 23, which generates a magnetic attraction force, attracting iron impurities in the quartz sand to achieve iron removal. After iron removal, the quartz sand moves towards the first housing 12 and finally falls into it. When the electromagnet 23 is full of iron impurities, quartz sand is temporarily added to the belt conveyor 11 or the belt conveyor 11 is stopped, and the linear moving machine is started via the controller. Mechanism 22, the linear motion mechanism 22 drives the electromagnet 23 to move towards one side of the belt conveyor 11, so that the electromagnet 23 is away from the conveying area of ​​the belt conveyor 11. Then, the controller cuts off the power to the electromagnet 23 to eliminate the magnetic force of the electromagnet 23. After the electromagnet 23 is demagnetized, the iron impurities fall off due to gravity and separate from the electromagnet 23. The linear motion mechanism 22 then drives the electromagnet 23 to reset. After resetting, the quartz sand is demagnetized again, and the separation of iron impurities from the magnet is completed. By utilizing the changing magnetic attraction of the electromagnet 23 and the characteristics of soft magnetic materials that are easy to magnetize and easy to demagnetize, the downtime of the whole device is effectively reduced.

[0030] like Figures 1 to 4 As shown, preferably, the conveying assembly 1 further includes a hopper 13; the hopper 13 is located at the end of the belt conveyor 11 away from the first housing 12; the discharge end of the hopper 13 faces the conveying area of ​​the belt conveyor 11. Preferably, the discharge end of the hopper 13 is a rectangular structure, the length of which corresponds to the width of the belt conveyor 11, so as to evenly distribute the quartz sand. In addition, a baffle can be set between the electromagnet 23 and the hopper. The baffle is set on the top surface of the belt conveyor 11, located on the conveying area of ​​the belt conveyor 11, and is spaced from the conveyor belt of the belt conveyor 11. The length of the baffle is consistent with the width of the belt conveyor 11. The baffle spreads the quartz sand conveyed by the belt conveyor 11 evenly, avoiding the accumulation of quartz sand and resulting in excessive thickness.

[0031] Example 2.

[0032] like Figures 1 to 4 As shown, compared with Embodiment 1, the difference lies in the following: a structural form of the support 21 is provided, which includes a portal frame 211, a support plate 212, and a slider 213; the portal frame 211 is distributed in parallel at intervals along the length direction of the belt conveyor 11, and the length direction of the portal frame 211 is consistent with the width direction of the belt conveyor 11, with the belt conveyor 11 located between two columns of the portal frame 211; the support plate 212 is disposed on the top of the portal frame 211, and the portal frame 211 supports the support plate 212; a slot is formed on the support plate 212 along the width direction of the belt conveyor 11; the linear motion mechanism 22 is connected to the electromagnet via the slider 213. 23 connection; one end of electromagnet 23 extends into the slot and connects to slider 213, slider 213 is slidably mounted on support plate 212; linear motion mechanism 22 is mounted on support plate 212; the movable end of linear motion mechanism 22 is connected to slider 213. Preferably, linear motion mechanism 22 is a lead screw slide, with a large adjustment range; the length of gantry frame 211 is greater than the width of electromagnet 23 and belt conveyor 11, expanding the movement range of electromagnet 23; when moving electromagnet 23, the movable end of linear motion mechanism 22 drives slider 213 to move, and electromagnet 23 moves with slider 213, thereby changing the position of electromagnet 23. The overall structure is simple and the design is reasonable.

[0033] like Figure 3 As shown, preferably, the bracket 21 also includes a pulley 214; the pulley 214 is rotatably disposed on the bottom surface of the slider 213; the pulley 214 drives the slider 213 to move along the length direction of the groove, increasing the moving speed of the slider 213 and shortening the downtime.

[0034] like Figures 2 to 4As shown, preferably, the iron removal component 2 also includes a second housing 24; the second housing 24 is located on one side of the belt conveyor 11, corresponding to the electromagnet 23; the top of the second housing 24 is an open end; the second housing 24 is located directly below the slot opening, and the second housing 24 collects the iron impurities that fall from the electromagnet 23, preventing the iron impurities from spilling.

[0035] 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.
