DETAILED DESCRIPTION

[0028] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings and examples, but the following examples are only used to illustrate the embodiments of the present application in detail, and do not limit the scope of the present application in any way.

[0029] Embodiment 1: A selection equipment for zirconium silicate bead production, referring to Figure 1 , comprising a stock bin 1, a discharging disc 2 below the stock bin 1, and a conveying mechanism below the discharging disc 2; the zirconium silicate bead 3 primary product in the stock bin 1 falls into the discharging disc 2 through the discharging port.

[0030] The conveying mechanism comprises a conveying belt 4, which advances to the end away from the discharging disc 2 and gradually inclines; a finished product collecting hopper 5 is arranged at the lower part of the lower end of the conveying belt 4, and a substandard product collecting hopper 6 is arranged at the lower part of the upper end of the conveying belt 4. The conveying belt 4 is installed on the rack and moves circularly under the drive of the rotating roller. The racks on both sides of the conveying belt 4 are respectively provided with baffles 11, which play a protective role and prevent the zirconium silicate beads 3 from rolling off from both sides of the conveying belt 4.

[0031] A vibrator 7 is arranged at the lower part of the discharging disc 2, which is used to vibrate the discharging disc 2 during the discharging process. The vibrator is installed on the rack below the discharging disc 2, which also plays a supporting role for the discharging disc. The side of the discharging disc 2 facing the conveying belt 4 is open, and the edge of the opening is flat. Side plates 12 are arranged at the other three sides. A material arranging rod 8 parallel to the opening of the discharging disc 2 is arranged at the middle of the discharging disc 2, and a gap is left between the material arranging rod 8 and the bottom of the discharging disc 2.

[0032] The zirconium silicate bead primary product falls into the discharging disc 2 from the discharging port at the lower part of the stock bin 1. With the vibration of the discharging disc 2, the zirconium silicate beads 3 slowly move to the side of the opening of the discharging disc 2. After passing through the gap between the material arranging rod 8 and the bottom of the discharging disc 2, the zirconium silicate beads 3 become flat and uniform in thickness, which facilitates the subsequent uniform discharging onto the conveying belt and makes the selection more detailed and comprehensive.

[0033] After the zirconium silicate beads 3 fall into the conveying belt 4 from the opening of the discharging disc 2, the spherical zirconium silicate bead products roll into the finished product collecting hopper 5 at the lower end, and the non-spherical products (strip-shaped, flat-shaped or other shapes) are brought to the front end of the conveying belt 4 and fall into the substandard product collecting hopper 6. In order to avoid the non-spherical products from sliding off the conveying belt, the conveying belt 4 should be made of appropriate materials, such as rubber, plastic or other anti-skid materials with appropriate friction coefficients, which are more conducive to the non-spherical products to stay and adhere to the conveying belt 4 and move upward. The discharging and selection process of the zirconium silicate beads refers to Figures 2-4 , the discharging process and selection of the zirconium silicate beads 3 shown in the figure are only for illustration. In actual work, the discharging process of the discharging disc 2 to the conveying belt 4 is relatively slow, and the zirconium silicate bead products falling on the conveying belt 4 are in a relatively sparse and scattered state, which does not cover the entire surface of the conveying belt 4, and even less likely to be stacked.

[0034] Further, an arc-shaped material blocking plate 9 is arranged outside the finished product collecting hopper 5, which serves as a protective function to prevent the rolling zirconium silicate beads 3 from falling outside the finished product collecting hopper 5.

[0035] A material brush 10 is arranged inside the substandard product collecting hopper 6 near the lower part of the conveying belt 4. The brush head of the material brush 10 is in contact with the lower surface of the conveying belt 4, which is used to brush off the substandard zirconium silicate beads adhered to the surface of the conveying belt 4 and make them fall into the substandard product collecting hopper 6.

[0036] Embodiment 2: A zirconium silicate bead production selection device, which is different from Embodiment 1 in that the discharging disc 2 and the conveying belt 4 are arranged in two groups, as shown in Figure 5 Another set of discharging disc 2 and conveying belt 4 is arranged below the upper conveying belt 4; the finished product collecting hopper 5 and the substandard product collecting hopper 6 are also arranged at both ends of the lower conveying belt 4; two groups of discharging pipes 13 are arranged below the hopper 1, and the lower ends of the discharging pipes 13 extend into the two discharging discs 2, respectively.

[0037] In the above embodiments, the side of the discharging disc 2 facing the conveying mechanism is inclined downward by an angle of 5-10°; the inclination angle of the conveying belt 4 is 10-30°; and the gap between the material straightening rod 8 and the bottom of the discharging disc 2 is 1-5 mm. The specific angle and gap size can be selected and determined according to the size of the produced zirconium silicate beads, and those skilled in the art can understand and implement the above technical solutions.

[0038] In the above embodiments, the device elements involved are all conventional device elements unless otherwise specified.

[0039] The specific working mode of the type selection equipment for zirconium silicate bead production is as follows: the zirconium silicate bead primary product falls from the bin to the discharge tray, and the zirconium silicate bead gradually moves to the open end in the vibration process of the discharge tray, becomes flat and uniform in thickness after passing through the gap between the material arranging roller and the bottom of the discharge tray, and gradually falls from the opening of the discharge tray to the conveying belt below. Since the particle size of the zirconium silicate bead product is extremely small (from tens of microns to several thousand microns) and the weight is also very light, the falling speed of the zirconium silicate bead can be adjusted by the vibration amplitude of the discharge tray, and the discharge speed is usually slow, and the amount of discharge per unit time is also small, so that the type selection of all zirconium silicate bead products can be more accurate and more comprehensive, and the specific discharge speed can be determined by the technical personnel according to the size of the actual product and the type selection requirement. The zirconium silicate bead falling on the conveying belt, wherein the product closer to the spherical shape directly rolls into the finished product collecting hopper at the lower end; other shaped products (such as long strip shape, flat shape) will stay on the conveying belt and be taken to the front end and fall into the defective product collecting hopper. The small particle size and light weight of the zirconium silicate bead determine that the spherical product is more likely to roll on the inclined conveying belt, and the non-spherical product is also easy to stay and adhere to the surface of the conveying belt. Therefore, the type selection equipment in the utility model can more accurately and comprehensively select the zirconium silicate bead product, and the round ball rate and uniformity of the finished zirconium silicate bead are higher, the quality of the finished product is greatly improved, and the utility model can be applied to the field with higher requirement for fine degree and higher precision.

[0040] The embodiments of the utility model are described in detail above in combination with the drawings and examples, but the utility model is not limited to the above-mentioned embodiments, and within the knowledge range of ordinary skilled persons in the art, changes or modifications can be made without departing from the purpose of the utility model.
