Description

Technical Field

[0001] The utility model relates to the technical field of dispersion devices, in particular to a dispersion device for magnesium oxide used in epoxy resin. Background Art

[0002] Epoxy resin, also known as artificial resin, is a type of organic high molecular polymer containing two or more epoxy groups in its molecular structure. It is a thermosetting plastic. Magnesium oxide is needed in the preparation process of epoxy resin. Conventional magnesium oxide is block-shaped. Since the contact area between block-shaped magnesium oxide and other liquids is smaller than the contact area between powdered magnesium oxide and other liquids, the reaction rate is reduced and it is not suitable for the preparation of epoxy resin. In order to increase the reaction rate, the block-shaped magnesium oxide is usually dispersed in the preparation of epoxy resin.

[0003] Chinese patent CN 219559837U discloses a magnesium oxide dispersion device, which can crush and grind magnesium oxide through a grinding device, and the grinding can improve the uniformity of the particle size. At the same time, the particle size of the material can be further subdivided through a screening device, and the material can be stored separately, which can facilitate the preparation operation and maintain the precision of the magnesium oxide dispersion device; however, the device cannot collect the magnesium oxide dust generated during the crushing process, thereby causing a waste of magnesium oxide.

[0004] Therefore, we proposed a dispersing device for epoxy resin using magnesium oxide to solve the problem. Utility Model Content

A driving wheel 312 is fixedly connected to the end, and the driving wheel 312 is rotatably connected to the transmission belt 313. A processing box 314 is fixedly installed on the right side of the fuselage 1. The outer side of the processing box 314 is rotatably connected to the third rotating shaft 315 through a bearing. The outer end of the third rotating shaft 315 is fixedly connected to a driven wheel 316, and the inner end of the third rotating shaft 315 is fixedly connected to a rotating fan 317. A baffle 318 is fixedly installed on the inner side of the processing box 314. A ventilation hole is provided on the outer side of the processing box 314. A filter frame 319 is inserted into the processing box 314. A first sliding groove 3110 is provided on the upper part of the processing box 314. A first sliding rod 3111 is fixedly connected to the inner wall of the first sliding groove 3110. A first sliding block 3112 is slidably connected to the outer wall of the first sliding rod 3111. A first spring 3113 is fixedly connected to the inner wall of the first sliding groove 3110, and a limiting plate 3114 is fixedly connected to the upper part of the first sliding block 3112.

[0032] In this embodiment, the output end of the motor 311 is fixedly connected to the first rotating shaft 4, and the driven wheel 316 is rotatably connected to the transmission belt 313. Through the cooperation of the motor 311, the first rotating shaft 4, the second rotating shaft 5, the first gear, and the second gear, the first crushing roller 6 and the second crushing roller 7 can rotate in opposite directions, so that the magnesium oxide can be crushed and processed, so that the magnesium oxide can be dispersed, which is convenient for subsequent use. At the same time, through the cooperation of the driving wheel 312, the transmission belt 313, the driven wheel 316, the third rotating shaft 315, the rotating fan 317, and the filter frame 319, the smoke generated during the crushing process of magnesium oxide can be collected, thereby preventing the waste of resources.

[0033] Furthermore, one end of the first spring 3113 is fixedly connected to the first slider 3112, and the bottom of the limiting plate 3114 is fitted with the outside of the filter frame 319.

[0034] Furthermore, the aperture of the baffle 318 is larger than the aperture of the filter frame 319 , and the baffle 318 can prevent larger particles of magnesium oxide from entering the processing box 314 , thereby preventing the mesh of the filter frame 319 from being blocked.

[0035] When the device is in use, the motor 311 is first turned on manually, and then the blocky magnesium oxide is manually added into the body 1 from the feed port, and the first rotating shaft 4 is driven to rotate by the motor 311, so that the first gear fixedly connected to the left end of the first rotating shaft 4 can be rotated. Since the first gear is meshed with the second gear, the first rotating shaft 4 can rotate, so that the first crushing roller 6 and the second crushing roller 7 can rotate in opposite directions, so that the magnesium oxide can be crushed and processed, so that the magnesium oxide can be dispersed, which is convenient for subsequent use. At the same time, under the action of the driving wheel 312, the transmission belt 313, and the driven wheel 316, the third rotating shaft 315 can be rotated by rotating the first rotating shaft 4, so that The rotating fan 317 fixedly connected to the inner end of the third rotating shaft 315 can be rotated. By rotating the rotating fan 317, the smoke and dust generated during the magnesium oxide processing can be absorbed into the processing box 314, and then the smoke and dust can be collected through the filter frame 319. Furthermore, when it is necessary to remove the filter frame 319, it is only necessary to manually push the limit plate 3114 to separate the limit plate 3114 from the outer side of the filter frame 319, and then the filter frame 319 can be manually taken out upward, so as to facilitate manual removal of the collected magnesium oxide powder and manual cleaning of the filter frame 319, thereby preventing the mesh of the filter frame 319 from being blocked, thereby affecting the collection effect of the magnesium oxide.

[0036] Example 2

[0037] On the basis of Example 1, a preferred embodiment of a dispersing device for epoxy resin magnesium oxide provided by the utility model is as follows Figures 1 to 5 As shown: the screening mechanism 32 includes a rotating rod 321 fixedly mounted on the outer wall of the first rotating shaft 4, a second sliding groove 322 is opened on the inner wall of the fuselage 1, a second sliding rod 323 is fixedly connected to the inner wall of the second sliding groove 322, a second sliding block 324 is slidably connected to the outer wall of the second sliding rod 323, a second spring 325 is fixedly connected to the inner wall of the second sliding groove 322, a screening frame 326 is fixedly connected to the outer side of the second sliding block 324, and a pressing rod 327 is fixedly connected to the upper part of the screening frame 326 through a connecting rod.

[0038] In this embodiment, one end of the second spring 325 is fixedly connected to the second slider 324. Through the cooperation of the pressure rod 327, the rotating rod 321, the second slide rod 323, the second slider 324, the second spring 325, and the screening frame 326, the crushed magnesium oxide can be screened, and the magnesium oxide can be further dispersed, so that magnesium oxide of different particle sizes can be screened out, which is more convenient for subsequent use.

[0039] Furthermore, there are two second sliders 324 symmetrically distributed in the fuselage 1 . By providing two second sliders 324 , the connection between the filter frame 326 and the fuselage 1 can be more stable, thereby making the filter frame 326 more stable when in use.

[0040] When the first rotating shaft 4 rotates, the rotating rod 321 fixedly connected to the outer wall of the first rotating shaft 4 can be rotated. Through the rotation of the rotating rod 321, the rotating rod 321 and the pressing rod 327 can be pressed against each other. Since the pressing rod 327 is fixedly connected to the screening frame 326 through the connecting rod, and under the action of the second sliding rod 323 and the second sliding block 324, the screening frame 326 can be moved downward, and then the screening frame 326 can be reciprocated up and down in the fuselage 1 by the elastic force of the second spring 325, so that the screening frame 326 can achieve a vibration effect, and then the crushed magnesium oxide can be vibrated and screened, and at the same time, the magnesium oxide can be further dispersed, and then magnesium oxide of different particle sizes can be screened out, which is more convenient for subsequent use.
