Description

Technical Field

[0001] The present application relates to the technical field of crystal granulation processing equipment, and in particular to a high-efficiency crushing device for granulating lanthanum titanate crystals. Background Art

[0002] At present, lanthanum titanate crystals have good ferroelectric, photocatalytic and electro-optical properties, and have very broad application prospects in the optical and electrical fields. It has been used in high-temperature electro-optical equipment and information storage, new high-performance microwave dielectric materials, high-temperature sensors and microwave piezoelectrics. In particular, it is used as a coating material with excellent performance in optoelectronic devices, such as display technology, imaging technology, light output and light integrated devices. Lanthanum titanate coating materials have a stable high refractive index, high homogeneity and high transmittance. At present, lanthanum titanate, as a coating material, has been widely used in the manufacture of high-performance optoelectronic devices.

[0003] The existing lanthanum titanate crystal granulating and crushing machine is too simple in function, consisting of only a percussion hammer driven by a cylinder and a screen. When in use, the staff needs to constantly push the crystals to the middle of the screen with a pusher, resulting in poor crushing effect, high dust generation and low work efficiency.

[0004] Our company has previously applied for a Chinese patent with the announcement number CN215878062U, which discloses a lanthanum titanate crystal granulating and crushing machine, including a frame, a crushing mechanism and a granulating mechanism, wherein the crushing mechanism is installed on the upper part of the frame, and the granulating mechanism is installed inside the frame. The utility model has a high degree of automation. When in use, the staff only needs to put the lanthanum titanate crystal to be crushed into the screen inside the groove of the placement table, and drive the knocking hammer to knock the crystal through the lifting cylinder, so that the crystal can be broken into granules and fall into the collection box through the screen. The setting of the trapezoidal screen can prevent the crystal from jumping out when knocking, suppress the generation of dust, and at the same time improve the screening efficiency and reduce labor costs.

[0005] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: although the above-mentioned technologies have solved to a certain extent the problem that the staff need to constantly use a pusher to push the crystals to the middle of the screen, resulting in poor crushing effect, there are still problems of poor crushing effect and high dust production, and there is still inconvenience in unloading.

[0013] Preferably, the dust suction pipe is connected to a trapezoidal funnel section close to a feeding port of the double-roll crusher, and the mouth of the dust suction pipe is tilted downward.

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The present application discloses a highly efficient crushing device for granulating lanthanum titanate crystals, referring to Figure 1 and Figure 2 , including a frame 1 and a double-roll crusher 11 installed on the frame 1. The principle of the double-roll crusher 11 is as follows: after the material enters the crushing chamber of the machine, the material is subjected to the meshing force of the rotating roller shaft, so that the material is forced to pass between the two rollers, and at the same time, it is squeezed and sheared by the roller shaft, and the material begins to break. The broken small particles are thrown to the bottom of the machine along the tangent of the roller rotation, through the gap between the two roller shafts, and the large particles exceeding the gap are further broken into small particles and discharged;

[0022] A sealing cover 2 is installed at the bottom of the frame 1, and a vibrating discharging mechanism and a dust hood 3 are arranged in the sealing cover 2. The vibrating discharging mechanism includes a vibrating screen 4 obliquely arranged at the bottom of the frame 1, springs 5 ​​are fixed at the four corners of the top of the vibrating screen 4, and the top of the spring 5 is fixed on the frame 1. A vibration motor 6 is fixed at the bottom of the vibrating screen 4, and a screen 41 is fixed on the surface of the vibrating screen 4. The setting of the screen 41 can ensure that the size of the particles produced is basically consistent, ensuring a good granulation effect. A discharge port 21 is opened on one side of the sealing cover 2 corresponding to the discharge end of the vibrating screen 4, and the dust hood 3 is arranged on a side away from the discharge port 21, and the dust suction port of the dust hood 3 is arranged toward the vibrating screen 4;

[0023] A feed trough 7 is fixed on the top of the feed inlet of the double-roll crusher 11. The feed trough 7 includes a vertical feed section 71 and two trapezoidal funnel sections 72. The two trapezoidal funnel sections 72 are symmetrically fixed on both sides of the vertical feed section 71. The trapezoidal funnel section 72 on one side is connected to the feed inlet of the double-roll crusher 11.

[0024] The setting of the two trapezoidal funnel sections 72 can prevent crystals from bouncing out. The bottom trapezoidal funnel section 72 can block most of the bouncing crystals, and when a small number of crystals enter the upper trapezoidal funnel section 72 from the vertical feed section 71, the power is very small and they will fall back into the double-roll crusher 11 under the action of gravity.

[0025] In order to reduce dust overflow at the feeding port of the double-roll crusher 11, a dust suction pipe 8 is connected to the side of the feeding trough 7, and the dust suction pipe 8 and the dust suction cover 3 are both externally connected to a dust collector.

[0026] The dust suction pipe 8 is connected to the trapezoidal funnel section 72 on one side of the feeding port of the double-roll crusher 11, and the mouth of the dust suction pipe 8 is tilted downward. This structural setting can reduce the chance of the bouncing crystals falling into the dust suction pipe 8.

[0027] Reference Figure 2 A material receiving box 9 is also provided in the sealing cover 2, and the material receiving box 9 is correspondingly arranged below the screen 41. A sealing door 22 that can be opened and closed for taking and placing the material receiving box 9 is provided on the side of the sealing cover 2, and an observation window (not shown in the figure) is provided on one side of the sealing cover 2.

[0028] By providing the material receiving box 9, slightly larger waste residues that cannot be sucked away by the vacuum cleaner can be collected for recycling.

[0029] The implementation principle of an efficient crushing device for granulating lanthanum titanate crystals in an embodiment of the present application is as follows: a worker puts large lanthanum titanate crystals from a feed trough 7 into a double-roll crusher 11, and the lanthanum titanate crystals begin to break. The broken small particles are thrown out to the bottom of the machine and fall onto the vibrating screen 4 through the gap between the two rollers along the tangent of the roller rotation, while the large particles of lanthanum titanate crystals exceeding the gap continue to be broken into small particles and discharged. During the vibration of the vibrating screen 4, the debris falls from the screen 41 into the receiving box 9, and the finished particles are discharged from the discharge port 21 on one side of the sealing cover 2. The whole process has a high degree of automation and a good crushing effect. In this process, the dust hood 3 and the dust pipe 8 can extract the dust generated by the crushing, thereby greatly reducing dust pollution.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
