[0002] Zirconium dioxide is an important inorganic compound. It is usually white, odorless and tasteless crystals. It is insoluble in water, hydrochloric acid and dilute sulfuric acid. It has a relative density of 5.85, a melting point of 2680℃, a boiling point of 4300℃, and a hardness second only to diamond. Zirconium dioxide is an important high-temperature resistant material, ceramic insulation material and ceramic sunscreen. It is used in the manufacture of advanced ceramics, enamel, refractory materials, etc.

[0003] Before using zirconium dioxide for processing, it is necessary to select its particles so that zirconium dioxide particles of different sizes can be screened and collected to facilitate the next step of processing;

[0004] However, when traditional zirconium dioxide particle selection devices are used to screen zirconium dioxide, most of them will use the slope screening method, which uses the weight of the zirconium dioxide particles to perform falling screening. This method has a poor effect on the classification of screened particles, and a small part of the particles will be mixed into the large particle classification, so multiple screening and particle selection are required to complete. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a secondary particle classifier for the preparation of zirconium dioxide, which can perform a more convenient triple particle selection and grouping function on zirconium dioxide particles, and at the same time can perform reciprocating shaking and screening on zirconium dioxide particles, so that the zirconium dioxide particles can be screened and selected more fully.

[0008] Furthermore, a feed pipe is fixed to one end of the outer protective shell, and a support frame is fixed to one end of the inner part of the outer protective shell close to the feed pipe, and the support frame is rotatably connected to the containing tank through a rotating shaft.

[0009] Furthermore, a storage bin is fixed at the bottom of the containing groove, and three groups of storage drawers are slidingly arranged inside the storage bin, and the three groups of storage drawers are arranged in a master-slave relationship with the first screen, the second screen and the third screen above, and a second handle is fixed on the front surface of the storage drawer.

[0010] Furthermore, blocking grooves are provided on the inner side of the containing groove and between the first screen and the second screen and between the second screen and the third screen, and blocking plates are clamped on the inner side of the blocking grooves.

[0011] Furthermore, a first handle is fixed to the top of the baffle plate, and the contact surfaces between the baffle plate and the baffle groove are smooth.

[0012] Furthermore, an electric telescopic rod is fixed to the top of the slider, and the output end of the electric telescopic rod is fixedly connected to the end of the storage bin away from the feeding pipe.

[0013] In summary, the present invention has the following beneficial effects:

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] In this example, see Figure 1 and Figure 2 A technical solution includes an outer protective shell 1 and a holding tank 4, wherein a feed pipe 2 is fixed to one end of the outer protective shell 1, and a support frame 3 is fixed to one end of the inner portion of the outer protective shell 1 close to the feed pipe 2, and the support frame 3 is rotatably connected to the holding tank 4 via a rotating shaft;

[0027] Among them, the outer protective shell 1 is the outer shell of the existing particle classifier, which is used to provide protection for the internal components and a warning range during operation. The feed pipe 2 is used to connect with the external feed pipe, and is used to input zirconium dioxide particles that need to be selected into the interior of the holding tank 4, and is fixedly connected to the outer protective shell 1 using the existing installation method. The support frame 3 is connected to the holding tank 4 through the existing rotating shaft, and is used to provide support function and stability for one end of the holding tank 4 connected to the support frame 3. The support frame 3 is fixedly installed with the outer protective shell 1 using the existing installation method. The holding tank 4 is used to hold zirconium dioxide particles that need to be screened and provide them with multiple particle selection functions.

[0028] For further information, see Figure 1 、 Figure 2 and Figure 3 The interior of the holding tank 4 is provided with a first screen 41, a second screen 42 and a third screen 43 in sequence. At the same time, a blocking groove 5 is provided on the inner side of the holding tank 4 and between the first screen 41 and the second screen 42 and the second screen 42 and the third screen 43. A blocking plate 6 is clamped on the inner side of the blocking groove 5. In addition, a first handle 7 is fixed to the top of the blocking plate 6, and the contact surface between the blocking plate 6 and the blocking groove 5 is smooth.

[0029] Among them, the first screen 41, the second screen 42 and the third screen 43 inside the holding tank 4 are all sub-screens of the same texture, and the sub-screen mesh numbers of the first screen 41, the second screen 42 and the third screen 43 are arranged in increasing order, among which the first screen 41 is the smallest and the third screen 43 is the largest. In addition, the interior of the holding tank 4 is located between the first screen 41 and the second screen 42 and between the second screen 42 and the third screen 43. Two groups of blocking grooves 5 are opened, and the blocking grooves 5 are polished and engaged with the contact surfaces with the baffle plate 6. The interior of the holding tank 4 can be divided into different screening and particle selection areas based on the first screen 41, the second screen 42 and the third screen 43. The first handle 7 on the top of the baffle plate 6 makes it convenient for the operator to extract the baffle plate 6, thereby improving the convenience and efficiency of the user during actual operation.

[0030] For further information, see Figure 1 、 Figure 2 and Figure 4 A storage bin 8 is fixed at the bottom of the storage tank 4, and three groups of storage drawers 9 are slidably arranged inside the storage bin 8. The three groups of storage drawers 9 are arranged in a master-slave relationship with the first screen 41, the second screen 42 and the third screen 43 above. In addition, a second handle 91 is fixed to the front surface of the storage drawer 9;

[0031] Among them, the storage bin 8 is fixedly connected to the holding tank 4 to form an integrated structure, and the storage drawer 9 slidingly arranged inside the storage bin 8 is used to collect the zirconium dioxide particles screened by the first screen 41, the second screen 42 and the third screen 43 inside the holding tank 4. The storage drawer 9 adopts the existing guide rails, card slots or other matching structures to slide smoothly inside the storage bin 8. At the same time, the second handle 91 on the front surface of the storage drawer 9 facilitates the operator to extract the storage drawer 9 from the inside of the storage bin 8, thereby improving the efficiency of the operator in uniformly collecting the screened particles.

[0032] For further information, see Figure 2 、 Figure 4 and Figure 5 , two sets of slide rails 101 are provided at the bottom of the outer protective shell 1, and the inside of the two sets of slide rails 101 is provided with a slide groove 102, and a slider 111 is slidably provided on the inner side of the slide groove 102, and auxiliary plates 112 are fixed at both ends of the slider 111 and are slidably provided with the slide rails 101, and several sets of auxiliary wheels 113 are provided at the bottom of the slider 111 and are slidably connected with the slide groove 102;

[0033] Among them, the slide rail 101 provides a smooth sliding state for the slider 111 through the internal slide groove 102, and the slider 111 forms a sliding structure inside the slide rail 101 through the auxiliary plate 112, so that the auxiliary plate 112 provides a limiting function and an auxiliary sliding function for the slider 111 when sliding inside the slide rail 101. The auxiliary wheel 113 is an existing moving wheel, which improves the sliding efficiency of the slider 111 in the slide groove 102 inside the slide rail 101.

[0034] For further information, see Figure 2 and Figure 4 , an electric telescopic rod 12 is fixed to the top of the slider 111, and the output end of the electric telescopic rod 12 is fixedly connected to the end of the storage bin 8 away from the feed pipe 2;

[0035] Among them, the electric telescopic rod 12 is an existing electric telescopic rod, and is electrically connected to the existing controller using the existing electrical connection method. At the same time, the electric telescopic rod 12 plays the role of a connecting support rod, fixing the slider 111 to the end of the storage bin 8 away from the feed pipe 2 to form an integrated structure.

[0036] The implementation principle of this embodiment is as follows: first, the outer protective shell 1 is stably placed in the designated position, and then the feed pipe 2 is connected to the external feed pipe, so that the zirconium dioxide particles that need to be screened are discharged into the interior of the holding tank 4. Before discharging the zirconium dioxide particles, the operator is required to pick up the baffle plate 6 through the first handle 7, and slide and plug it into the baffle groove 5 between the first screen 41 and the second screen 42 inside the holding tank 4, and ensure that the lateral position of the holding tank 4 is horizontal. Then, when an appropriate amount of zirconium dioxide particles enters the interior of the holding tank 4 and is located above the first screen 41, the electric telescopic rod 12 on the top of the slider 111 is opened, so that it drives the storage bin 8 away from one end of the feed pipe 2 to enter. When the hopper 10 is lifted up, the storage bin 8 will synchronously drive the holding tank 4 above it to rise synchronously by the rise of one end. Then, the holding tank 4 will rotate in a circle around the center point connected to the rotating shaft of the support frame 3. At the same time, the slider 111 under the electric telescopic rod 12 will move toward one end of the feeding pipe 2 in the slide groove 102 opened inside the slide rail 101. The horizontal direction of the holding tank 4 is controlled by the lifting and lowering of the electric telescopic rod 12, and the zirconium dioxide particles inside the holding tank 4 are shaken and screened, so that the screening of the zirconium dioxide particles becomes more sufficient. Finally, the storage drawer 9 under the first screen 41 is pulled out by pulling the second handle 91, and the zirconium dioxide particles that meet the size are collected and taken out.

[0037] When multiple screenings are required, after the screening of the first screen 41 is completed, the holding tank 4 is moved away from one end of the feed pipe 2 and higher than the other end, and the zirconium dioxide particles inside the holding tank 4 are moved away from the baffle plate 6, the electric telescopic rod 12 stops, and then the baffle plate 6 is pulled out through the first handle 7 and placed inside the baffle tank 5 between the second screen 42 and the third screen 43, and then the electric telescopic rod 12 is started again, so that the zirconium dioxide inside the holding tank 4 can be screened and selected above the second screen 42, and then the zirconium dioxide can be screened and selected on the third screen 43 in the same manner as the above steps, and finally all the storage drawers 9 under the storage bin 8 are pulled out through the second handle 91 to collect the zirconium dioxide particles screened and selected by the first screen 41, the second screen 42 and the third screen 43 respectively, and all the zirconium dioxide particles that have not passed through the holding tank 4 can be distinguished and collected.
