[0024] The multi-level filter tank for phenolic resin production of the utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.
[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0026] See also Figure 1-Figure 4 The multi-level filter tank for phenolic resin production of this embodiment can filter through two filter channels. When the channel is blocked due to excessive impurities, another channel is switched for filtering, so that the blocked filter box 2 can be cleaned without stopping the work. It can also achieve secondary filtration, so that the impurities in the liquid are filtered more cleanly, and the production quality and accuracy of the liquid are guaranteed. In this embodiment, it mainly includes a filter frame 1, and at least two filter boxes 2 are detachably provided on the filter frame 1. The larger impurities in the liquid are filtered through the filter box 2. The filter box 2 is designed to be opened up and down, and the interior of the filter box 2 is horizontally and parallelly provided with multiple groups of filter components 8. A suitable number of filter components 8 can be added according to actual conditions.
[0027] The filter assembly 8 includes a fixed filter plate 81 mounted inside the filter box 2, and a rotating filter plate 82 is coaxially rotated at the bottom of the fixed filter plate 81. The rotating filter plate 82 is embedded in the fixed filter plate 81, and the outer diameter of the rotating filter plate 82 is smaller than the outer diameter of the fixed filter plate 81. It is convenient to rotate the rotating filter plate 82, and avoid the situation where the fixed filter plate 81 is stuck on the rotating filter plate 82. Multi-stage filtration is achieved, and impurities of different sizes are filtered by grouping. A control board 9 is fixedly arranged at one end of the rotating filter plate 82 facing away from the filter frame 1. A control slot 10 for the control board 9 to move is opened on the filter box 2, and the control slot 10 passes through the fixed filter plate 81. A scale group 11 is arranged on the filter box 2 below the control slot 10, and a handle 12 is fixedly arranged at both the front and rear ends of the filter box 2. The control board 9 is slid in the control slot 10 to make the rotating filter plate 82 and the fixed filter plate 81 rotate relative to each other, thereby changing the aperture size of the rotating filter plate 82 and the fixed filter plate 81 that can pass the liquid. In this process, the position of the control plate 9 can be observed through the scale group 11 to achieve the control of different pore sizes of multiple groups of filter components 8. In this way, the pore size in the filter channel can be controlled to ensure the accuracy of filtering.
[0028] In order to switch the filter channel and clean the impurities. Figure 1 and Figure 2In this embodiment, a branch cylinder 3 that matches the position of the filter box 2 is horizontally rotatably provided on the top of the filter frame 1, and the branch cylinder 3 is rotatably provided on the filter frame 1 above the filter box 2 along the front-to-back direction. A liquid separation port 13 corresponding to the number box of the filter box 2 is provided on the branch cylinder 3. A rotating disk 14 is rotatably provided at the front end of the filter frame 1, and the rotating disk 14 is fixedly provided at the front end of the branch cylinder 3. When the filter channel is blocked, the rotating disk 14 is rotated to rotate the branch cylinder 3 to rotate the liquid separation port 13 that is discharging liquid upward, and the other liquid separation port 13 above is rotated downward to another filter box 2, thereby realizing the change of the channel. At this time, the blocked channel can be cleaned. Then, filtering is performed through the two filter channels, and when there are too many impurities and blockage occurs, another channel can be switched for filtering, so that the blocked filter box 2 can be cleaned without stopping work.
[0029] The top of the filter frame 1 is provided with a liquid inlet 4 connected to the branch cylinder 3. The rear end of the liquid inlet 4 is provided with a liquid inlet port 15, and the liquid inlet 4 is connected to the branch cylinder 3 through at least one liquid inlet pipe 16 fixedly provided at the bottom end thereof. Liquid is poured in through multiple liquid inlet pipes 16 to reduce resistance when the branch cylinder 3 rotates.
[0030] In order to achieve secondary filtration. In this embodiment, see Figure 1 , Figure 2 and Figure 4 , the bottom end of the filter frame 1 is connected and fixedly provided with a filter cartridge 5, and the bottom end of the filter cartridge 5 is connected and provided with a liquid outlet 6. The outside of the filter cartridge 5 is fixedly provided with a support base frame 7 for supporting the filter cartridge 5. The filter cartridge 5 is designed to be opened up and down, and a bearing plate 17 is fixedly provided at the bottom end of the filter cartridge 5. A filter cloth 18 is placed on the bearing plate 17 inside the filter cartridge 5, and a cover plate 19 is hingedly provided at the front end of the filter cartridge 5. A handle 12 is also provided on the cover plate 19, and the cover plate 19 is sealed and fixed to the filter cartridge 5 by bolts. The liquid filtered by the filter box 2 enters the filter cartridge 5, and is then filtered again by the filter cloth 18 inside the filter cartridge 5, and the filtered liquid is discharged through the liquid outlet 6. Thus, secondary filtration is achieved through different filtering methods, and the filter cloth 18 can be conveniently removed and replaced by the hinged cover plate 19. The lowest end of the liquid outlet 6 is higher than the lowest end of the support base frame 7. It is convenient to collect the liquid flowing out of the liquid outlet 6.
[0031] The method of using the multi-level filter tank for phenolic resin production of the utility model is as follows: first, the filter assembly 8 is placed in the filter box 2, and then the filter box 2 is embedded in the filter frame 1. According to the actual situation on site, the control plate 9 is slid in the control tank 10 to make the rotating filter plate 82 and the fixed filter plate 81 rotate relative to each other, thereby changing the aperture size of the rotating filter plate 82 and the fixed filter plate 81 that can pass the liquid. In this process, the position of the control plate 9 can be observed through the scale group 11 to realize the control of multiple groups of filter assemblies 8 with different aperture sizes.
[0032] When filtering, the liquid enters the liquid inlet tank 4 from the liquid inlet port 15, and is poured into the branch cylinder 3 from multiple liquid inlet pipes 16. The resistance of the branch cylinder 3 during rotation is reduced by multiple liquid inlet pipes 16. The liquid entering the branch cylinder 3 flows into the corresponding filter box 2 through the liquid separation port 13. At this time, the liquid is filtered for the first time through multiple groups of fixed filter components 8 with different pore sizes. The filtered liquid flows into the filter cylinder 5 and is filtered twice through the filter cloth 18, so that the impurities in the liquid are filtered more cleanly and the production quality of the liquid is guaranteed. The filtered liquid is discharged through the liquid outlet 6.
[0033] When the filter channel is clogged, the rotating disk 14 is rotated to rotate the branch cylinder 3 to rotate the liquid separation port 13 that is discharging upward, and the other liquid separation port 13 above is rotated downward to another filter box 2, and the liquid is filtered through another filter box 2, thereby changing the channel. At this time, the clogged channel can be cleaned. Then, filtering is performed through two filter channels. When there are too many impurities and blockage occurs, another channel is switched for filtering, so that the clogged filter box 2 can be cleaned without stopping work. When the filter cloth 18 needs to be replaced, the cover plate 19 can be opened by the handle 12 to replace the filter cloth 18.
