Description

Technical Field

[0001] This utility model relates to the field of quartz sand technology, and in particular to a quartz sand particle size classifier. Background Technology

[0002] Quartz sand is a siliceous granular material made from natural quartz ore through processes such as crushing, washing, screening, and drying. Its main component is SiO2 (silicon dioxide), and it features high hardness (Mohs 7), corrosion resistance, and good chemical stability. It is widely used in industries such as glass, ceramics, casting, water treatment, and photovoltaics. After crushing, quartz sand needs to be screened using a particle size analyzer to facilitate subsequent processing and use.

[0003] The existing quartz sand particle size classifier has the following shortcomings when in use: When the quartz sand particle size classifier uses a vibrating motor to shake the screen to classify quartz sand, the quartz sand that does not pass through the screen is not easy to discharge quickly. As the usage time increases, the quartz sand that does not pass through the screen will clog the screen, thus affecting the classification effect of the quartz sand particle size classifier.

[0004] Therefore, those skilled in the art have proposed a quartz sand particle size classifier to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned quartz sand particle size classifier, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a quartz sand particle size classifier, which solves the problem that quartz sand that has not passed through the screen is inconvenient to discharge quickly.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quartz sand particle size classifier, comprising:

[0009] A grading mechanism, comprising a grading box, wherein two sets of mounting frames are installed on the inner wall of the grading box, and each set of mounting frames is connected to a screening screen, wherein the aperture of the upper screening screen is larger than that of the lower screening screen, for grading and screening of quartz sand.

[0010] The feeding assembly includes a driving structure, which includes two sets of fixed plates disposed in the inner cavity of the grading box, and each set of fixed plates is slidably connected to a telescopic pusher plate.

[0011] The drive structure, in conjunction with the fixed plate and the telescopic pusher plate, moves on the screening screen to clean the quartz sand on the screen.

[0012] In a preferred embodiment of the quartz sand particle size classifier of this utility model, the driving structure includes a fixed plate fixed to the outer wall of the classifier box, a reduction motor is mounted on the fixed plate, and the output end of the reduction motor is connected to a worm gear through a rotating shaft.

[0013] In a preferred embodiment of the quartz sand particle size classifier of this utility model, the outer wall of the classifier box is rotatably connected to a drive gear via a bearing, and the drive gear is connected to a worm gear transmission.

[0014] In a preferred embodiment of the quartz sand particle size classifier of this utility model, the inner wall of the classifier is connected to two sets of rotating lead screws, both sets of lead screws penetrate the classifier, and meshing wheels are fixedly connected to both sets of lead screws, and both sets of meshing wheels are meshed with the drive gear.

[0015] As a preferred embodiment of the quartz sand particle size classifier of this utility model, the inner wall of the classifier box is provided with two sets of guide grooves, and a slider is slidably connected in each set of guide grooves.

[0016] In a preferred embodiment of the quartz sand particle size classifier of this utility model, a threaded sleeve is threadedly connected to the lead screw, and the two ends of the threaded sleeve are respectively fixedly connected to the slider and the fixed plate.

[0017] As a preferred embodiment of the quartz sand particle size classifier of this utility model, the classification mechanism further includes a feed hopper connected to the top of the classification box, and multiple sets of vibration motors are installed on the inner wall of the classification box, with the output end of the vibration motor connected to the mounting frame.

[0018] As a preferred embodiment of the quartz sand particle size classifier of this utility model, the side wall of the classifier is provided with two sets of discharge ports, and a collection box is installed on the outside of each set of discharge ports. The bottom of the inner cavity of the classifier is provided with a collection box that is slidably through it.

[0019] The beneficial effects of this utility model are as follows: The reduction motor of the drive structure on the feeding assembly drives the worm to rotate. Since the worm is connected to the drive gear, and the drive gear is meshed with two sets of meshing wheels, the rotation of the worm drives the lead screw fixed to the meshing wheels to rotate. After the threaded sleeve connected to the lead screw is limited by the sliding limit of the guide groove and the slider, the threaded sleeve drives the fixed plate and the telescopic pusher plate to move on the two sets of screening screens, which can quickly discharge the screened quartz sand from the discharge port without the need for regular manual cleaning, effectively preventing the screening screen from clogging and effectively improving the efficiency of quartz sand particle size classification.

[0030] Example 1

[0031] Reference Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a quartz sand particle size classifier that can quickly discharge quartz sand that has not passed through the screen, including:

[0032] The grading mechanism 100 includes a grading box 101. Two sets of mounting frames 106 are installed on the inner wall of the grading box 101. Each set of mounting frames 106 is connected to a screening screen 107, and the aperture of the upper screening screen 107 is larger than that of the lower screening screen 107, for the grading and screening of quartz sand.

[0033] The feeding assembly 200 includes a drive structure 201, which includes two sets of fixed plates 202 disposed in the inner cavity of the grading box 101. Each set of fixed plates 202 is slidably connected to a telescopic pusher plate 203.

[0034] It should be noted that when the screening screen 107 vibrates, the telescopic pusher plate 203 can move up and down within the fixed plate 202, and the telescopic pusher plate 203 will never detach from the fixed plate 202.

[0035] The drive structure 201, together with the fixed plate 202 and the telescopic pusher plate 203, moves on the screening screen 107 to clean the quartz sand on the screening screen 107.

[0036] In use, the quartz sand to be graded is poured into the grading box 101. The quartz sand particles are graded by two sets of sieves 107 with different aperture sizes. The quartz sand that does not pass through the two sets of sieves 107 will remain on top. Through the action of the drive structure 201 on the feeding component 200, the fixed plate 202 and the telescopic pusher plate 203 can move to the right on the two sets of sieves 107, which can quickly discharge the quartz sand that does not pass through the two sets of sieves 107. There is no need for manual cleaning at regular intervals, which can effectively prevent the sieves 107 from clogging and effectively improve the efficiency of quartz sand particle size grading.

[0037] Example 2

[0038] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the drive structure 200 includes a fixing plate 201a fixed to the outer wall of the grading box 101. A geared motor 201b is mounted on the fixing plate 201a, and the output end of the geared motor 201b is connected to a worm gear 201c through a rotating shaft. The electrical end of the geared motor 201b is electrically connected to the electrical end of an external power supply and a controller (installed at the front end of the grading box 101) through wires, and can control the forward and reverse rotation of the geared motor 201b.

[0039] Among them, the outer wall of the grading box 101 is rotatably connected to the drive gear 201d through the bearing, and the drive gear 201d is connected to the worm gear 201c for transmission.

[0040] The inner wall of the grading box 101 is connected to two sets of rotatably mounted lead screws 201f, and both sets of lead screws 201f penetrate the grading box 101. Both sets of lead screws 201f are fixed with meshing wheels 201e, and both sets of meshing wheels 201e are meshed with the drive gear 201d. The end of the lead screw 201f near the discharge port 103 is rotatably connected to the inner wall of the grading box 101 through a bearing.

[0041] The grading box 101 has two sets of guide grooves 201h on its inner wall, and each set of guide grooves 201h is slidably connected to a slider 201i.

[0042] Among them, the lead screw 201f is threadedly connected to a threaded sleeve 201g, and the two ends of the threaded sleeve 201g are respectively fixedly connected to the slider 201i and the fixing plate 202.

[0043] The grading mechanism 100 also includes a feed hopper 102 connected to the top of the grading box 101. Multiple sets of vibrating motors 108 are installed on the inner wall of the grading box 101, and the output end of the vibrating motor 108 is connected to the mounting frame 106. The vibration of the vibrating motor 108 causes the two sets of screening screens 107 to vibrate, thereby realizing the grading of quartz sand.

[0044] The grading box 101 has two sets of discharge ports 103 on its side wall. Each set of discharge ports 103 is equipped with a collection box 104 on its outer side. The bottom of the inner cavity of the grading box 101 is provided with a collection box 105 that is slidably through it.

[0045] When in use, the quartz sand is poured into the grading box 101 through the feed hopper 102, and the vibration motor 108 is started. The vibration of the vibration motor 108 causes the two sets of screening screens 107 to vibrate, thereby achieving the grading of the quartz sand. The quartz sand that falls through the lower screening screen 107 is collected into the collection box 105.

[0046] When it is necessary to clean the quartz sand that has not passed through the two sets of screening screens 107, the controller controls the reduction motor 201b on the feeding assembly 200 to work. The reduction motor 201b drives the worm 201c to rotate. Since the worm 201c is connected to the drive gear 201d, and the drive gear 201d is meshed with the two sets of meshing wheels 201e, the rotation of the worm 201c drives the lead screw 201f, which is fixed to the meshing wheel 201e, to rotate. After the threaded sleeve 201g, which is threaded to the lead screw 201f, slides and is limited by the guide groove 201h and the slider 201i, the threaded sleeve 201g drives the fixed plate 202 and the telescopic pusher plate 203 to move to the right on the two sets of screening screens 207. The screened quartz sand can be quickly discharged from the discharge port 103 and collected into the collection box 104.

[0047] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
