Technical Field

[0001] This application relates to the technical field of phenolic resin production, and specifically relates to a filtering device for phenolic resin production. Background Technique

[0002] Phenolic resin is a colorless or yellowish-brown transparent substance, resistant to weak acids and weak bases, decomposes when exposed to strong acids, corrodes when exposed to strong bases, insoluble in water, and soluble in organic solvents such as acetone and alcohol. Phenolic resin is obtained by polycondensation of phenol aldehyde or its derivatives.

The bottom of the gantry crane is connected to a metal mesh cage. A transmission component is arranged inside the metal mesh cage. A drying chamber is installed below the gantry crane. The top of the drive motor inside the drying chamber is connected to a turntable. A fixing component is arranged inside the turntable. In this utility model, by setting the fixing component, when the motor drives the first gear to rotate, the screw can rotate synchronously. Since the thread directions on both ends of the screw are opposite, the two clamping blocks can move towards each other to complete the clamping and fixing of the metal mesh cage, making the stability of the metal mesh cage higher. In this utility model, by setting the transmission component, the drive motor can drive the transmission head to rotate. Under the connection and transmission of the transmission head and the transmission cap, the rotating shaft can rotate, and the rotating shaft will drive the stirring plate to stir the phenolic resin for easy flushing, making the filtering effect better.

It is necessary to disconnect the connection between the gantry crane and the metal mesh cage to make the metal mesh cage rotate normally in the drying pool. At the same time, when placing the metal mesh cage into the filtering pool and the drying pool, it is necessary to continuously adjust the position of the metal mesh cage to make the metal mesh cage work normally in the filtering pool and the drying pool, which consumes a certain amount of time and reduces the working efficiency of filtering phenolic resin.

[0040] Please refer to Figure 2 and Figure 3 , a guide plate 8 is arranged at the bottom of the limiting plate 9. The guide plate 8 is arranged obliquely. The outer surface of one side of the guide plate 8 is slidably connected to the outer surface of one side of the limiting block 22.

The oblique arrangement of the guide plate 8 can guide the limiting block 22, so that the limiting block 22 can accurately move between two adjacent limiting plates 9.

[0041] Please refer to Figure 2 and Figure 3 , the number of the limiting plates 9 is eight. Every two limiting plates 9 form a group. The outer surfaces of one side of each group of two limiting plates 9 are respectively slidably connected to the outer surfaces of both sides of the limiting block 22. By means of the cooperation of the limiting block 22 and two adjacent limiting plates 9, the angle of the connecting ring 2 can be limited, so as to avoid the connection between the connecting ring 2 and the gantry crane 1 from affecting the rotation of the metal mesh cage 4.

[0042] Please refer to Figure 3 and Figure 4 , the number of the limiting rings 3 is two.

[0043] Please refer to Figure 2 , Figure 3 and Figure 5, the top of the second positioning block 21 is provided with a quadrangular pyramid. The areas and inclination angles of the four conical surfaces of the quadrangular pyramid at the top of the second positioning block 21 are all set to be equal. The outer surface of the middle part of the second positioning block 21 is inserted into the inner wall of the positioning groove at the bottom of the metal mesh cage 4. The shape of the second positioning block 21 is adapted to the shape of the inner wall of the positioning groove at the bottom of the metal mesh cage 4. The installation angle of the metal mesh cage 4 can be guided through the quadrangular pyramid provided at the top of the second positioning block 21, so that the metal mesh cage 4 can be conveniently connected to the second positioning block 21. The square setting at the bottom of the second positioning block 21 can stably cooperate with the positioning groove at the bottom of the metal mesh cage 4 to position the metal mesh cage 4.

[0044] In the filtering device for phenolic resin production in this embodiment, the limiting block 22 restricts the rotation of the connecting ring 2 through the limiting plate 9, so that when the metal mesh cage 4 rotates, the connecting ring 2 will rotate between the two limiting rings 3, avoiding the connection between the connecting ring 2 and the gantry crane 1 from affecting the rotation of the metal mesh cage 4, achieving the effect that the metal mesh cage 4 can be driven to rotate in the drying tank 17 without disconnecting the connection between the metal mesh cage 4 and the gantry crane 1, and there is no need to frequently connect and disconnect the connection between the metal mesh cage 4 and the gantry crane 1.

[0045] The working principle of the above embodiment is as follows: The gantry crane 1 drives the metal mesh cage 4 into the filtration tank 13 through the connection ring 2 and the limiting ring 3. When the metal mesh cage 4 moves downward, the inner wall of the positioning groove at the bottom will contact the outer surface of the quadrangular pyramid at the top of the first positioning block 16. The position of the metal mesh cage 4 in the filtration tank 13 is adjusted through the guidance of the outer surface of the quadrangular pyramid at the top of the first positioning block 16, so that the metal mesh cage 4 is connected to the first positioning block 16 through the positioning groove at the bottom. When the metal mesh cage 4 moves downward in the filtration tank 13, the inner wall of the connection groove at the bottom of the connecting sleeve 7 will contact the outer surface of the quadrangular pyramid at the top of the socket 10. The socket 10 will guide the angle of the connecting sleeve 7 through the connection groove at the bottom of the connecting sleeve 7, so that the socket 10 is stably connected to the socket 10 through the connection groove at the bottom. The heating plate 14 works to heat the water in the filtration tank 13, so that the impurities in the phenolic resin dissolve in the water. The first motor 11 works to drive the second stirring plate 12 to work, stirring the water in the filtration tank 13, so that the water in the filtration tank 13 fully contacts the phenolic resin. When the first motor 11 works, it will drive the connecting sleeve 7 to rotate through the socket 10, so that the connecting sleeve 7 drives the first stirring plate 6 to rotate in the metal mesh cage 4 through the rotating shaft 5, so that the first stirring plate 6 stirs the phenolic resin for easy flushing. Then, the metal mesh cage 4 is lifted out of the filtration tank 13 by the gantry crane 1, and the gantry crane 1 drives the metal mesh cage 4 into the drying tank 17. When the metal mesh cage 4 moves downward in the drying tank 17, the outer surface of the quadrangular pyramid at the top of the second positioning block 21 will guide the metal mesh cage 4 through the inner wall of the positioning groove at the bottom of the metal mesh cage 4, adjusting the position of the metal mesh cage 4 in the drying tank 17, so that the positioning groove at the bottom of the metal mesh cage 4 is connected to the second positioning block 21 to fix the position of the metal mesh cage 4. At the same time, when the metal mesh cage 4 moves downward in the drying tank 17, the guide plate 8 will guide the limiting plate 9 through the limiting block 22, so that the limiting block 22 can be accurately inserted between two adjacent limiting plates 9 to fix the angle of the connection ring 2. The second motor 18 works to drive the rotating ring 20 to rotate. The rotating ring 20 drives the metal mesh cage 4 to rotate through the second positioning block 21. When the metal mesh cage 4 rotates, the connection ring 2 will rotate between the two limiting rings 3, so that the metal mesh cage 4 can rotate stably in the drying tank 17, and thus the phenolic resin in the metal mesh cage 4 is evenly dried in the drying tank 17.
