Description

Technical Field

[0001] The utility model relates to the technical field of phenol filtering devices, in particular to a filter for phenol production. Background Art

[0002] o-Aminophenol, also known as 2-aminophenol, is a chemical intermediate used to make sulfur dyes, azo dyes, fur dyes and fluorescent whitening agent EB, etc. It can also be used in medicine or pesticides. o-Aminophenol is usually obtained by reducing o-nitrophenol. After the reduction reaction is completed, the catalyst and other solid phases in the obtained reaction solution need to be filtered and recovered before the subsequent product purification process can be carried out.

[0003] Existing filtering devices usually use filter plates, filter cloths, filter membranes, etc. as the retention medium for solid phases. As the filtering process continues, the solid phases continue to accumulate on the retention medium, causing the filtering resistance to gradually increase, while the filtering efficiency decreases accordingly. In order to ensure the sealing of the filter, the filtering structure of most phenol filters is not convenient to disassemble, resulting in a long time-consuming disassembly and replacement, and it is not convenient to use. Therefore, a filter for phenol production is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a filter for phenol production, including a shell 1, a feed hopper 2 is fixedly connected to the top of the shell 1, and the medicine is convenient to enter the middle of the shell 1 through the feed hopper 2. A movable plate 3 is slidably connected to the middle of the shell 1, and a sealing structure is installed between the shell 1 and the movable plate 3 to achieve a sealed connection between the shell 1 and the movable plate 3. This is a prior art and will not be described in detail here. The movable plate 3 is used to place filter screens, filter cloths, etc. A baffle 22 is fixedly connected to the inside of the shell 1, and the movable plate 3 is located below the baffle 22. A handle 21 is fixedly connected to the outside of the movable plate 3. The top of the movable plate 3 is blocked by the baffle 22 to prevent the medicine from flowing along the inner wall of the shell 1 to the joint between the shell 1 and the movable plate 3.

[0032] Reference Figure 2-Figure 4, a placement groove 4 is provided in the middle of the movable plate 3 for placing the filter screen and filter cloth. A protrusion 5 is fixedly connected to the outer side of the shell 1, and a plug rod 7 is slidably connected to the middle of the protrusion 5. A spring 8 is sleeved on the outer periphery of the plug rod 7, and the plug rod 7 is reset by the spring 8. A housing 6 is fixedly connected to the top of the protrusion 5, and the spring 8 is located inside the housing 6. The spring 8 can be stored and the position of the plug rod 7 can be limited by the housing 6. A plug hole 9 is provided on the outer side of the movable plate 3, and the spring 8 and the plug hole 9 are engaged. By engaging the spring 8 and the plug hole 9, the position of the movable plate 3 can be limited, so that the filter screen can be installed, and vice versa, the filter screen or filter cloth can be disassembled. A limiting ring 19 is fixedly connected to the outer side of the plug rod 7, one end of the spring 8 is connected to the limiting ring 19, and the other end is connected to the top of the housing 6. The position of the plug rod 7 is limited by the limiting ring 19 to prevent the plug rod 7 from extending excessively. The top of the plug rod 7 is fixedly connected with a pull ring 20, which is located above the housing 6, so as to facilitate pulling out the plug rod 7, thereby better replacing the filter screen and filter cloth. The bottom of the housing 1 is slidably connected with a support assembly to support the device.

[0033] Reference Figure 1-Figure 2 The support assembly includes a fixed block 10, which is fixedly connected to the bottom of the housing 1. A movable block 11 is slidably connected to the bottom of the fixed block 10. A support leg 13 is fixedly connected to the bottom of the movable block 11. Through the fixed block 10, the movable block 11 and the support leg 13, the housing 1 can slide back and forth while supporting the device. A wedge block 12 is fixedly connected to the top of the movable block 11, and the fixed block 10 is slidably connected to the upper part of the movable block 11 through the wedge block 12. The connection between the movable block 11 and the fixed block 10 is reinforced by the wedge block 12, so that the sliding of the housing 1 is smoother and more stable. A vibration assembly is fixedly connected to the outside of the support assembly. The vibration assembly causes the housing 1 to reciprocate, thereby improving the filtering effect.

[0034] Reference Figure 2 and Figure 5 The vibration assembly includes a mounting plate 14, which is fixedly connected between the two legs 13. A motor 15 is fixedly connected to the outside of the mounting plate 14, and the motor 15 provides power. A rotating rod 16 is fixedly connected to the output end of the motor 15, and a cross bar 17 is fixedly connected to the outside of the housing 1. A hoop 18 is fixedly connected to the other end of the cross bar 17, and the hoop 18 is sleeved on the outer periphery of the rotating rod 16. By driving the motor 15 to work, the rotating rod 16 can be rotated, and under the action of the cross bar 17 and the hoop 18, the housing 1 can slide back and forth on the movable block 11, thereby accelerating the filtration speed of the solution, thereby improving the service life of the filter.

[0035] Working principle: When in use, first set the filter screen or filter cloth in the middle of the movable plate 3, the middle of the filter cloth is located in the middle of the placement groove 4, and the outer edge of the filter cloth is connected to the movable plate 3, and then the movable plate 3 is installed, and then the liquid to be filtered is put into the shell 1 from the feed hopper 2, and then when the liquid passes through the movable plate 3, the filtration is completed. After a period of use, the pull ring 20 can be pulled upward to move the insertion rod 7 upward, so that the insertion rod 7 is disengaged from the middle of the socket 9, and the spring 8 is squeezed. At this time, the movable plate 3 can be pulled out, so as to facilitate the replacement of the filter screen or filter cloth in the middle of the placement groove 4. After the replacement is completed, the movable plate 3 is pushed in. When the insertion rod 7 reaches the position of the socket 9, the position restriction of the movable plate 3 can be completed under the action of the spring 8.

[0036] Secondly, when filtering, the rotating rod 16 can be rotated by driving the motor 15, and the housing 1 can slide back and forth on the movable block 11 under the action of the cross bar 17 and the hoop 18, thereby accelerating the filtration speed of the solution and avoiding the problem of uniform clogging of the filter screen due to the standing of the liquid, thereby extending the service life of the filter screen.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
