Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, specifically to a device for removing impurities from high-purity quartz sand. Background Technology

[0002] High-purity silica sand is the material foundation for the development of high-tech industries, with applications in fields such as optical fiber, military, and aerospace. These fields have extremely stringent requirements for the purity of silica sand raw materials, demanding very low impurity content.

[0003] The existing technical solution has at least the following drawbacks: Existing quartz sand impurity removal equipment can typically screen out impurities in quartz sand and then use a magnetic field to remove weakly magnetic impurity minerals. However, it is inconvenient to intermittently discharge the screened quartz sand, resulting in a large amount of quartz sand being discharged, which in turn affects the efficiency of magnetic removal of weakly magnetic impurity minerals from the quartz sand. Therefore, improvements are urgently needed. Thus, we propose a high-purity quartz sand impurity removal device. Utility Model Content

[0004] The purpose of this invention is to provide a high-purity quartz sand impurity removal device, which solves the problem mentioned in the background technology that it is inconvenient to intermittently discharge the sieved quartz sand, resulting in a large amount of sieved quartz sand being discharged, which in turn affects the magnetic adsorption removal efficiency of weak magnetic impurity minerals in quartz sand.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-purity quartz sand impurity removal device, including an impurity removal box, a slag discharge door is rotatably installed on one side of the lower end of the impurity removal box via a hinge, a screening screen is detachably installed on the upper end of the inner cavity of the impurity removal box, a discharge channel is welded inside the impurity removal box, and a multi-stage electric cylinder is fixedly installed on the other side of the impurity removal box.

[0006] The upper end of the multi-stage electric cylinder is fixedly connected to a fixing frame, and the lower end of the fixing frame is fixedly installed with multiple fixing strips. Multiple fixing rings are detachably installed in the middle of the discharge channel. A baffle is provided through the upper end of the discharge channel, and a connecting rod is welded to the lower end of the baffle. The other end of the connecting rod passes through the lower end of the other side of the impurity removal box and is fixedly connected to the multi-stage electric cylinder.

[0007] By adopting the above technical solution, the fixed frame can move the fixed bar back and forth at the top of the screening screen, thereby agitating the quartz sand accumulated on the screening screen and improving the screening efficiency of the quartz sand. In addition, during the left and right movement of the connecting rod, the connecting rod will drive the baffle to move left and right, thereby changing the discharge port on the baffle in the discharge channel. This achieves intermittent discharge of the screened quartz sand, avoiding the large-scale discharge of screened quartz sand, which would affect the magnetic adsorption removal efficiency of weak magnetic impurities in the quartz sand.

[0008] Optionally, the lower end of the fixing strip is attached to the upper end of the screening screen, and the fixing strips are evenly distributed.

[0009] By adopting the above technical solution, the fixing strip can be moved along with the fixing frame during the movement of the fixing frame, so that the fixing strip can move the quartz sand on the screening screen back and forth.

[0010] Optionally, multiple electromagnets are fixedly installed on the inner side of the fixing ring, and the electromagnets are arranged in a ring.

[0011] By adopting the above technical solution and setting up an electromagnet, weakly magnetic impurity minerals can be magnetically removed from the quartz sand passing through the discharge channel.

[0012] Optionally, the baffle is positioned above the fixed ring and is movably connected to the discharge channel.

[0013] By adopting the above technical solution and setting up baffles, the discharge port can be controlled, thereby controlling the feeding of quartz sand.

[0014] Optionally, the baffle has multiple discharge ports inside, and the discharge ports are equidistant from each other.

[0015] By adopting the above technical solution and setting the discharge port, the screened quartz sand can be conveniently discharged from the discharge port into the fixed ring for magnetic attraction.

[0016] Optionally, the front end of the impurity removal box is sealed with an observation window.

[0017] By adopting the above technical solution and setting up an observation window, it is convenient for staff to observe the screening process of the screening mesh.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the setting of an impurity removal box, a slag discharge door, a screening screen, a multi-stage electric cylinder, a fixing ring, an electromagnet, a connecting rod, a baffle, and a discharge port, can both enable the fixing frame to drive the fixing bar to move back and forth at the upper end of the screening screen, thereby agitating the quartz sand accumulated on the screening screen and improving the screening efficiency of quartz sand. Furthermore, during the left and right movement of the connecting rod, the connecting rod will drive the baffle to move left and right, thereby changing the discharge port on the baffle within the discharge channel. This achieves intermittent discharge of the screened quartz sand, avoiding the large-scale discharge of screened quartz sand, which would affect the magnetic adsorption removal efficiency of weakly magnetic impurities in the quartz sand.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a high-purity quartz sand impurity removal device, including an impurity removal box 1, a slag discharge door 12 is rotatably installed on one side of the lower end of the impurity removal box 1 via a hinge, a screening screen 13 is detachably installed on the upper end of the inner cavity of the impurity removal box 1, a discharge channel 14 is welded inside the impurity removal box 1, and a multi-stage electric cylinder 2 is fixedly installed on the other side of the impurity removal box 1.

[0026] A fixed frame 21 is fixedly connected to the upper end of the multi-stage electric cylinder 2. Multiple fixing strips 22 are fixedly installed at the lower end of the fixed frame 21. Multiple fixing rings 23 are detachably installed in the middle of the discharge channel 14. A baffle 4 is provided through the upper end of the discharge channel 14. A connecting rod 3 is welded to the lower end of the baffle 4. The other end of the connecting rod 3 passes through the lower end of the other side of the impurity removal box 1 and is fixedly connected to the multi-stage electric cylinder 2. The baffle 4 is located above the fixing rings 23 and is movably connected to the discharge channel 14. Next, the discharge port 5 can be controlled by the baffle 4, thereby controlling the feeding of quartz sand. Multiple discharge ports 5 are opened inside the baffle 4 and are evenly distributed between the discharge ports 5. The discharge ports 5 facilitate the discharge of the screened quartz sand from the discharge port 5 into the fixed ring 23 for magnetic attraction. The front end of the impurity removal box 1 is sealed with an observation window 11. The observation window 11 facilitates the staff to observe the screening of the screening screen 13.

[0027] The lower end of the fixing strip 22 is attached to the upper end of the screening screen 13, and the fixing strips 22 are evenly distributed. By setting the fixing strips 22, the fixing strips 22 can be driven to move along with the fixing frame 21 during the movement, so that the fixing strips 22 can move the quartz sand on the screening screen 13 back and forth.

[0028] Multiple electromagnets 24 are fixedly installed on the inner side of the fixing ring 23, and the electromagnets 24 are arranged in a ring. By setting the electromagnets 24, weak magnetic impurity minerals can be magnetically removed from the quartz sand passing through the discharge channel 14.

[0029] During the removal process, the quartz sand is first screened for impurities through the screening screen 13. At the same time, the multi-stage electric cylinder 2 is activated, which drives the fixed frame 21 and the connecting rod 3 to move left and right simultaneously. This causes the fixed frame 21 to move the fixed bar 22 back and forth at the upper end of the screening screen 13, thereby agitating the quartz sand accumulated on the screening screen 13 and improving the screening efficiency. Meanwhile, as the connecting rod 3 moves left and right, it also drives the baffle 4 to move left and right, causing the discharge port 5 on the baffle 4 to change within the discharge channel 14. This allows for intermittent discharge of the screened quartz sand, preventing a large amount of screened quartz sand from being discharged, which would affect the magnetic removal efficiency of weakly magnetic impurities in the quartz sand.
