Description

Technical Field

[0001] The utility model relates to the technical field of rubber production equipment, and more specifically to a rubber antioxidant production and purification device. Background Art

[0002] Rubber antioxidant plays a vital role in the production of rubber products. It can effectively delay rubber aging and extend the service life of rubber products. However, there are many problems in the purification process of the existing rubber antioxidant production process. In the production process of rubber antioxidant, it is necessary to separate the rubber antioxidant from a mixture containing impurities, by-products, etc. to improve its purity and quality so that it can meet specific performance indicators and application requirements. The presence of these impurities will affect the purity and performance of the rubber antioxidant. These impurities with larger particle sizes can be separated by screening to ensure the purity of the product. The ultrasonic circular vibrating screen can achieve efficient screening of rubber antioxidant particles by adjusting the frequency and amplitude of the ultrasonic wave and the vibration parameters of the vibrating screen.

[0003] However, the screen frame and the equipment on the existing vibrating screen are mostly connected by buckles or bolts. Although the installation speed of buckles is slightly faster than that of bolts, it is still necessary to adjust the position of the buckles one by one and perform the buckling operation. Especially for multi-layer screen frames, the installation process of multiple buckles is relatively cumbersome, which increases the installation time cost. When using bolt connections, it is necessary to use tools (such as wrenches) to tighten the bolts one by one. During the installation process, the tightening degree of the bolts must be consistent, otherwise the screen frame may be installed unevenly. When disassembling, it is also necessary to loosen the bolts one by one. The operation process is very time-consuming and will affect production efficiency. This disadvantage is more obvious, especially when the screen needs to be replaced frequently or the screen frame needs to be cleaned and maintained. Utility Model Content

[0021] Figure 1-Figure 5 It is the best embodiment of the utility model, and the following Figure 1-Figure 5 The utility model is further described.

[0022] Specifically, a rubber antioxidant production and purification device includes a screening machine body 1 and a first screen frame 2, a second screen frame 3 and a cover plate 5 placed in sequence from bottom to top. The tops of the first screen frame 2 and the second screen frame 3 are fixedly connected with a positioning ring 6, the interior of the positioning ring 6 is provided with a sealing groove 7, the inner wall of the sealing groove 7 is provided with a clamping groove 8, the inner top of the sealing groove 7 is provided with a guide groove 9, the interior of the positioning ring 6 is provided with a limiting groove 10, the interior of the positioning ring 6 is fixedly connected with a vent pipe 61, and the interior of the limiting groove 10 is sealingly and slidably connected with a rubber sealing disk 11. The bottom of the rubber sealing disk 11 is fixedly connected with an annular pressure plate 12, and the outer surface of the annular pressure plate 12 is sealingly and slidably connected to the interior of the positioning ring 6. A vent pipe 13 is fixedly connected inside the positioning ring 6, a sealing cavity 14 is provided inside the second screen frame 3 and the first screen frame 2, a sealing block 15 is sealingly and slidingly connected inside the sealing cavity 14, a clamping block 16 is fixedly connected to the surface of the sealing block 15, a spring 18 is movably installed inside the sealing cavity 14, and a sealing gasket 19 is fixedly connected to the bottom of the cover plate 5 and the second screen frame 3. The outer edge of the cover plate 5 can be sealed and connected to the clamping groove 8.

[0023] In this embodiment, by setting the card block 16 and the card slot 8, after the first screen frame 2, the second screen frame 3 and the cover plate 5 are stacked in sequence, the first screen frame 2 and the second screen frame 3 can be quickly fixed to each other by pressing the second screen frame 3 downward, and the connection is well sealed after fixing. After the purification is completed, the first screen frame 2 and the second screen frame 3 can also be quickly disassembled from each other, without the need for cumbersome bolt tightening or other complicated connection operations as in the traditional way, which greatly saves installation time, especially when the equipment needs to be assembled quickly for production, it can significantly improve the installation speed of the entire equipment, reduce the preparation time before the equipment is started, and improve production efficiency.

[0024] Specifically, a sealing ring 151 is fixedly installed on the outer surface of the sealing block 15, the bottom of the clamping block 16 is arc-shaped, and steel balls 161 are equidistantly and movably installed inside the clamping block 16. The top of the steel ball 161 extends to the upper surface of the clamping block 16, and the top of the steel ball 161 abuts against the inner top of the clamping slot 8.

[0025] In this embodiment, the friction between the block 16 and the inner wall of the slot 8 can be reduced by providing the steel ball 161. When the sealing chamber 14 is under negative pressure, the sealing block 15 can quickly drive the block 16 to slide, thereby improving the response speed and the splitting efficiency.

[0026] Specifically, the clamping groove 8 is annular, the inner wall of the guide groove 9 is arc-shaped, the number of the positioning rings 6 is two, and the outer surface of the sealing gasket 19 is sealed and fitted inside the sealing groove 7 .

[0027] In this embodiment, since the inner wall of the guide groove 9 is arc-shaped, when the second screen frame 3 is pressed downward, the clamping block 16 can be automatically clamped in the clamping groove 8 .

[0028] Specifically, the outer surface of the block 16 is clamped in the slot 8, and the surface of the block 16 away from the sealing block 15 extends to the outside of the second screen frame 3. Under normal conditions, the sealing block 15 drives the block 16 to slide toward the slot 8 due to the elasticity of the spring 18.

[0029] In this embodiment, by providing the spring 18 , when no pressure is applied to the annular pressure plate 12 , the clamping block 16 can be automatically clamped in the clamping groove 8 .

[0030] Specifically, the bottom ends of the outer surfaces of the second screen frame 3 and the cover plate 5 are inserted into the sealing groove 7 , and the inner top end of the limiting groove 10 is connected to the outside of the positioning ring 6 through the air release pipe 61 .

[0031] In this embodiment, by providing an air venting pipe 61 , when the rubber sealing disc 11 slides upward, the air at the top of the inner portion of the limiting groove 10 can be discharged through the air venting pipe 61 , thereby ensuring smooth sliding of the rubber sealing disc 11 .

[0032] Specifically, the inner bottom end of the limiting groove 10 is connected to the inside of the sealing cavity 14 through the ventilation pipe 13 , and the outer surface of the annular pressure plate 12 is sealingly slidably connected to the inside of the positioning ring 6 .

[0033] In this embodiment, since the outer surface of the annular pressure plate 12 is sealingly and slidably connected to the inside of the positioning ring 6, the sealing of the bottom end of the inner part of the limiting groove 10 can be ensured.

[0034] The working principle and use process of this utility model:

[0035] When the second screen frame 3 needs to be disassembled, the annular pressure plate 12 is pressed, and the annular pressure plate 12 drives the rubber sealing disk 11 to slide upward. At this time, the air at the top of the limiting groove 10 is discharged through the vent pipe 61, and the space below the rubber sealing disk 11 inside the limiting groove 10 is in a negative pressure state, and through the vent pipe 13, the inside of the sealing chamber 14 is also in a negative pressure state. Due to the negative pressure, the sealing block 15 drives the block 16 to slide away from the slot 8, and the spring 18 is in a compressed state. The surface of the steel ball 161 is rollingly connected to the inner wall of the slot 8. When the block 16 is completely separated from the inside of the slot 8, the second screen frame 3 drives the sealing pad 19 to separate from the surface of the positioning ring 6.

[0036] When the rubber antioxidant needs to be purified and screened, after the first screen frame 2, the second screen frame 3 and the cover plate 5 are stacked in sequence, the second screen frame 3 is pressed downward so that the block 16 is clamped in the inside of the card slot 8, so that the first screen frame 2 and the second screen frame 3 can be quickly fixed to each other. And the connection is well sealed after fixation. Then pour the material into the second screen frame 3 through the cover plate 5, and start the screening machine body 1 for screening. There is no need to perform cumbersome bolt tightening or other complicated connection operations as in the traditional way, which greatly saves installation time, especially when the equipment needs to be assembled quickly for production, it can significantly improve the installation speed of the entire equipment, reduce the preparation time before the equipment is started, and improve production efficiency.
