Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a quartz powder screening machine. Background Technology

[0002] Quartz powder is a fine powder made from quartz ore through crushing, grinding and other processes. Quartz is a common mineral whose main component is silicon dioxide, and it has good chemical stability and high temperature resistance.

[0003] Quartz powder is not the same as quartz sand. Quartz sand has a particle size of less than 120 mesh, while quartz powder has a particle size of more than 120 mesh. Common specifications for quartz powder include 120 mesh, 200 mesh, 260 mesh, 325 mesh, 600 mesh, 800 mesh, 1000 mesh, and 2000 mesh. A quartz powder screening machine is an instrument used to screen quartz powder and separate it into different mesh sizes.

[0004] Current quartz screening machines include vibrating screens, ultrasonic screens, and air classifiers. Standard stainless steel vibrating screens are generally used for screening. However, conventional vibrating screens rely solely on vibration to separate quartz powder of different mesh sizes. Since quartz powder contains a certain amount of iron powder after crushing and processing, it needs to be treated. This results in a secondary iron removal process for the quartz powder of different mesh sizes after screening with a vibrating screen. The specific method is to use a magnet to remove the iron. This additional process increases the complexity of the sorting process. Therefore, this application designs a quartz powder screening machine to solve this technical defect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a quartz powder screening machine, which has the advantages of simultaneously completing the screening and iron removal steps of quartz powder, thereby improving processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quartz powder screening machine, comprising a screening machine body, wherein a baffle frame is fixedly installed at the top outer edge of the screening machine body, and an iron removal mechanism is provided on the baffle frame;

[0007] The iron removal mechanism includes two mounting frames mounted on the baffle frame, a main shaft rotatably connected between the two mounting frames, an iron removal fan disposed outside the main shaft, and a geared motor for driving the main shaft to rotate relative to the mounting frames.

[0008] A bushing is also fixedly installed on the outside of the main shaft. The iron removal fan includes a U-shaped frame fixedly installed on the outside of the bushing, a sliding plate slidably connected to the U-shaped frame, and a magnetic block fixed to the end of the sliding plate.

[0009] By adopting the above technical solution, the main shaft can be rotated by controlling the reduction motor, so that the iron removal fan located outside the main shaft sweeps across the surface of the screening machine body as the main shaft rotates and removes the iron powder contained in the quartz powder located above the screening machine body.

[0010] As a preferred technical solution of this utility model, the iron removal fan is continuously distributed in several units on the outer surface of the bushing.

[0011] The U-shaped frame has an overall U-shaped structure, and the inner wall of the U-shaped frame has grooves extending toward both ends of the U-shaped frame. The two sides of the slide plate are slidably connected to the grooves.

[0012] The above technical solution improves the sliding stability of the skateboard relative to the U-shaped frame.

[0013] As a preferred embodiment of this utility model, a waste frame is fixedly installed on one side of the two mounting brackets, and the waste frame transitions into an arc shape at one edge near the main shaft.

[0014] By adopting the above technical solution, motion interference caused by the hard contact of the sliding plate against the surface of the waste box can be avoided.

[0015] As a preferred embodiment of this utility model, a spring is connected between the skateboard and the U-shaped frame, with one end of the spring fixedly connected to the U-shaped frame and the other end fixedly connected to the skateboard.

[0016] By adopting the above technical solution, the slide plate can easily contact the edge of the waste box under the push of the spring, scraping off most of the iron powder and letting it fall into the waste box.

[0017] As a preferred embodiment of this utility model, a limiting groove is provided on the side of the skateboard, and a limiting key is raised on the inner top of the U-shaped frame, and the limiting key is slidably connected relative to the limiting groove.

[0018] The above technical solution restricts the sliding of the skateboard relative to the U-shaped frame to prevent it from falling off.

[0019] As a preferred embodiment of this invention, the magnetic block is inserted into the interior of the slide plate from the end of the slide plate away from the bushing.

[0020] By adopting the above technical solution, the slide plate can pass through the quartz powder near the top of the screening machine body and draw out the iron powder contained in the quartz powder.

[0021] As a preferred embodiment of this utility model, the geared motor drives the main shaft to rotate clockwise in relation to the waste frame.

[0022] The above technical solution is adopted to facilitate the scraping of iron powder into the waste frame through a top-down contact method.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This quartz powder screening machine is suspended above the existing screening machine body via an iron removal fan connected by a mounting frame. By installing magnetic blocks at the end of the sliding plate of the iron removal fan structure, a rotating wheel can be formed to adsorb and separate iron powder contained in the quartz powder, thus simultaneously completing the sorting and iron removal processes. In addition, by setting the sliding plate to slide relative to the U-shaped frame and fixing a waste frame to one side of the mounting frame, it is also possible to facilitate the separation of some adsorbed iron powder during the rotation of the iron removal fan structure, thereby ensuring the effectiveness of multiple iron removal processes. The iron powder is collected uniformly in the waste frame, which facilitates subsequent cleaning and improves the practicality of the device. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 4The quartz powder screening machine in this embodiment includes a screening machine body 1, which is composed of a conventional linear chamber connecting support and a vibration motor. A baffle frame 2 is fixedly installed on the top outer edge of the screening machine body 1, and an iron removal mechanism is provided on the baffle frame 2 for removing iron powder contained in the quartz powder in the screening machine body 1.

[0032] The iron removal mechanism includes a mounting frame 3 that is fixed to the baffle frame 2 by bolts. There are two mounting frames 3 symmetrically distributed above the baffle frame 2. The mounting frames 3 provide installation positions for the remaining components of the iron removal mechanism to be suspended above the screening machine body 1 for installation.

[0033] Furthermore, the iron removal mechanism also includes a main shaft 4 rotatably connected between two mounting brackets 3, an iron removal fan 7 disposed outside the main shaft 4, and a geared motor 5 for driving the main shaft 4 to rotate relative to the mounting brackets 3.

[0034] With the above-mentioned mechanism, the main shaft 4 can be rotated by controlling the reduction motor 5, so that the iron removal fan 7 located outside the main shaft 4 sweeps across the surface of the screening machine body 1 as the main shaft 4 rotates and removes the iron powder contained in the quartz powder located above the screening machine body 1.

[0035] In this embodiment, a bushing 6 is also fixedly installed on the outside of the main shaft 4. The iron fan 7 includes a U-shaped frame 701 fixedly installed on the outside of the bushing 6, a sliding plate 703 slidably connected to the U-shaped frame 701, and a magnetic block 704 fixed to the end of the sliding plate 703.

[0036] As can be further explained, the magnetic block 704 is embedded into the slide plate 703 from the end of the slide plate 703 away from the bushing 6, so that the slide plate 703 can pass through the quartz powder close to the top of the screening machine body 1 when it swings, and then pull out the iron powder contained in the quartz powder.

[0037] It is understandable that there are several iron removal fans 7 continuously distributed on the outside of the bushing 6, and therefore there are also several sliding plates 703 on the outside of the bushing 6. As the main shaft 4 rotates, the iron removal process of the continuously fed quartz powder can be completed by the alternating swing of several sliding plates 703.

[0038] In this embodiment, the U-shaped frame 701 has an overall U-shaped structure. The inner wall of the U-shaped frame 701 is provided with a sliding groove 702 extending toward both ends of the U-shaped frame 701. The two sides of the sliding plate 703 are slidably connected to the sliding groove 702.

[0039] This design improves the sliding stability of the skateboard 703 compared to the U-shaped frame 701.

[0040] Furthermore, a spring 8 is connected between the slide plate 703 and the U-shaped frame 701. One end of the spring 8 is fixedly connected to the U-shaped frame 701, and the other end is fixedly connected to the slide plate 703. The spring 8 pushes the slide plate 703 to slide away from the bushing 6.

[0041] Furthermore, a scrap frame 11 is fixedly installed on one side of each of the two mounting brackets 3. The scrap frame 11 transitions into an arc shape at one edge near the main shaft 4.

[0042] This design allows the slide plate 703 to easily contact the edge of the waste box 11 under the push of the spring 8, scraping off most of the iron powder and letting it fall into the waste box 11. At the same time, due to the rounded transition design at the edge of the waste box 11, it can also prevent the slide plate 703 from hard contacting the surface of the waste box 11 and causing motion interference.

[0043] To prevent the slide plate 703 from sliding relative to the U-shaped frame 701 and falling off, a limiting groove 10 is provided on the side of the slide plate 703, and a limiting key 9 is raised on the inner top of the U-shaped frame 701. The limiting key 9 is slidably connected relative to the limiting groove 10.

[0044] During the specific sliding engagement process, as the limit key 9 slides along the limit groove 10, it can slide and abut against the edge of the limit groove 10, thereby completing the limit position restriction of the sliding limit position of the slide plate 703 relative to the U-shaped frame 701.

[0045] It should be noted that the length of the limiting groove 10 should be selected according to the actual distance between the main shaft 4 and the screen of the screening machine body 1, so as to avoid the slide plate 703 contacting the screen of the screening machine body 1 during rotation. At the same time, the reduction motor 5 pulls the main shaft 4 to rotate clockwise in relation to the waste frame 11, so as to scrape the iron powder into the waste frame 11 through a top-down contact method.

[0046] The working principle of the above embodiment is as follows: the iron removal fan 7 and the main shaft 4 in the iron removal mechanism are pre-assembled, and the main shaft 4 is connected between two mounting frames 3 and controlled by the geared motor 5. Then, the mounting frame 3 is fixed to the baffle frame 2 above the existing screening machine body 1 by bolts to complete the loading. When the screening machine body 1 is running, the geared motor 5 is turned on at the same time.

[0047] Quartz powder is fed from one side of the screen of the screening machine body 1 to the top of the screening machine body 1 for sorting. The quartz powder is distributed along the straight direction of the screen of the vibrating screen. At this time, the reduction motor 5 rotates between the two mounting brackets 3 by traction of the main shaft 4, so that several iron removal fans 7 fixed to the outside of the main shaft 4 by the bushing 6 rotate with the main shaft 4. The slide plate 703 structure in the iron removal fan 7 continuously sweeps across the screen surface of the screening machine body 1 through the magnetic block 704 embedded at its end during the rotation, so that the iron powder contained in the quartz powder passing through the iron removal fan 7 is adsorbed and separated from the quartz powder by several magnetic blocks 704, thus completing the iron removal of the quartz powder.

[0048] As the main shaft 4 rotates, the slide plate 703 of the iron removal fan 7 located outside the main shaft 4 is pushed by the spring 8 and rotates to one side of the waste box 11. When the slide plate 703 contacts the outer edge of the waste box 11, it can scrape off most of the iron powder adsorbed by the magnetic block 704. The iron powder falls into the waste box 11 and is collected. Several iron removal fans 7 repeat the above process, which can facilitate subsequent cleaning.

[0049] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
