Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying devices, in particular to a drying device for preparing a modified magnesium hydroxide flame retardant. Background Art
[0002] Modified magnesium hydroxide is usually used as a flame retardant and plays a flame retardant role in polymers and rubber products. Magnesium hydroxide is a water-containing substance with a certain degree of hydration. When preparing modified magnesium hydroxide flame retardants, a drying device is usually required to dry the original magnesium hydroxide particles or powder to remove the moisture therein.
[0003] When using a drying device, the material is generally placed into the drying device through the feed port, and then the dryer on one side is started to continuously increase the heat inside the drying device to achieve the purpose of drying the material. However, in actual operation, the materials are placed into the drying device at the same time. During the process of waiting for drying, the material inside the drying device will have uneven thickness. If the material layer thickness in some areas is too thick or too thin, it will cause uneven heat transfer, resulting in uneven drying. And because the modified magnesium hydroxide flame retardant has some viscosity, if uneven drying occurs during the drying process, it will cause the incompletely dried material to stick to the inside of the drying device.
[0004] In summary, the current drying device for preparing modified magnesium hydroxide flame retardant still has the following defects during use:
[0005] 1. The material is dried unevenly during the drying process;
[0006] 2. Uneven drying will cause the material to stick to the inner wall of the drying device. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them.

Example 1
[0032] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a drying device for preparing a modified magnesium hydroxide flame retardant, the drying device for preparing a modified magnesium hydroxide flame retardant comprises a main body 1, a drying machine 2 installed on one side of the main body 1, a feed port 3 and an exhaust gas outlet 4 installed on the top of the main body 1, a connecting piece 5 is installed at the bottom of the main body 1, a mixing piece 6 is provided inside the main body 1, a discharging piece 7 is installed at the bottom of the connecting piece 5, and a conveyor belt 8 is provided at the bottom of the discharging piece 7;
[0033] The mixing element 6 includes a motor 61 installed on the other side of the main body 1, and the motor 61 is located on the side away from the dryer 2. The main body 1 is internally rotatably connected to a rotating shaft 62, and the output end of the motor 61 extends to the inside of the main body 1 and is fixedly connected to the rotating shaft 62. A rotating plate 63 is fixedly connected to the surface of the rotating shaft 62, and a mixing plate 64 is installed inside the rotating plate 63. A scraper 65 is installed at one end of the mixing plate 64 and away from the end of the rotating plate 63. One side of the scraper 65 is in contact with the inner wall of the main body 1 to prevent the material from sticking to the inner wall of the main body 1. The feed port 3 and the exhaust gas outlet 4 are far away from each other. The setting of the mixing plate 64 can drive the material inside the main body 1 to roll, thereby avoiding the phenomenon of material accumulation, further promoting the consistency of material thickness, and the mixing elements 6 are arranged equidistantly.
[0034] The mixing plate 64 is arranged in a trapezoidal shape, and a trapezoidal groove is provided inside the rotating plate 63. The mixing plate 64 is located inside the trapezoidal groove and is movably connected thereto. The arrangement of the trapezoidal groove enables the mixing plate 64 to be connected to the rotating plate 63 and to perform preliminary positioning.
[0035] A nut 66 is fixedly connected to one side of the rotating plate 63, and a bolt 67 is provided inside the rotating plate 63. The bolt 67 passes through the mixing plate 64 and extends to the outside of the rotating plate 63 to be threadedly connected to the nut 66. The setting of the bolt 67 can make the connection between the rotating plate 63 and the mixing plate 64 more stable, and can achieve the purpose of quickly replacing the mixing plate 64.
[0036] During use, the material to be dried is put into the interior of the main body 1 through the feed port 3, and the dryer 2 is started to gradually increase the temperature inside the main body 1. Then the motor 61 is started to drive the rotating shaft 62 to rotate, and drive the rotating plate 63 to rotate along the inside of the main body 1, and at the same time drive the mixing plate 64 and the scraper 65 to rotate, so that the scraper 65 rotates along the inner wall of the main body 1. As the rotating plate 63 and the mixing plate 64 rotate, the material inside the main body 1 can be driven to roll continuously, thereby avoiding the accumulation of materials inside the main body 1 and the problem of uneven thickness. In the process of rotation, the rotating plate 63 will also drive the scraper 65 to rotate along the inner wall of the main body 1 to prevent the material from sticking to the inner wall of the main body 1, further solving the problem of the material sticking to the inner wall of the main body 1.
[0037] When replacing the mixing plate 64 and the scraper strip 65, it is only necessary to reversely twist the bolt 67 to cancel the connection with the nut 66, and then horizontally move the mixing plate 64 until it is completely separated from the rotating plate 63 to complete the operation. During installation, the operation is reversed, so that the purpose of quickly replacing the mixing plate 64 and the scraper strip 65 can be achieved. Example 2
[0038] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0039] The connecting member 5 includes a connecting pipe 53 located at the bottom of the main body 1 . The connecting pipe 53 is communicated with the interior of the main body 1 . The connecting pipe 53 can transport the dried material to the interior of the discharging member 7 .
[0040] A retaining ring 52 is provided inside the connecting tube 53, and a rotating rod 51 is fixedly connected to one side of the retaining ring 52. The rotating rod 51 extends to the outside of the connecting tube 53, and a connecting block 54 is fixedly connected to the bottom of the connecting tube 53. The setting of the retaining ring 52 can limit the material, and the rotating rod 51 can facilitate the control of the retaining ring 52.
[0041] The discharging member 7 comprises a discharging block 71 installed at the bottom of the connecting block 54 , and a motor 72 is installed on one side of the discharging block 71 .
[0042] The discharging block 71 has a discharging roller 73 movably sleeved inside, and the output end of the motor 72 extends to the inside of the discharging block 71 and is fixedly connected to the discharging roller 73. The discharging roller 73 can transport the dried material evenly on the surface of the conveyor belt 8. The uniform discharging does not require frequent manual adjustment or monitoring, which can reduce the need for manual intervention, improve the degree of automation, and save human resources. The discharging roller is composed of a spiral screw.
[0043] After the drying is completed, the rotating rod 51 is rotated to drive the retaining ring 52 to flip to ninety degrees. At this time, the material flow area is maximized, and the material can fall into the inside of the discharging block 71 through the connecting pipe 53 and the connecting block 54. Then the motor 72 is started to drive the discharging roller 73 to rotate. Since the inside of the discharging roller 73 is composed of a spiral screw, the spiral screw can convey the material along the direction of the spiral line. Due to the rotation of the spiral screw, the material will naturally move forward under the action of the spiral, thereby achieving uniform and continuous discharging. Uniform discharging does not require frequent manual adjustment or monitoring, which can reduce the need for manual intervention, improve the degree of automation, and save human resources.
[0044] The dried material will slowly move to the surface of the conveyor belt 8 according to the rotation of the discharge roller 73, thereby completing the overall operation.
[0045] The remaining structures are the same as those of Example 1.
[0046] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
