Description

Technical Field

[0001] The present invention belongs to the technical field of polyetheretherketone processing, and particularly relates to a washing kettle for preparing polyetheretherketone. Background Art

[0002] Polyetheretherketone is a high polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure. It belongs to semi-crystalline polymer materials and has physical and chemical properties such as high temperature resistance and chemical resistance. The long-term use temperature of PEEK can reach 260 °C, and the instantaneous use temperature can even reach 300 °C. Its melting point is as high as 343 °C, and the glass transition temperature is 143 °C, which is widely used in many fields.

[0003] In the process of preparing polyetheretherketone, many processing steps are required, and washing is a very important step. In the process of washing polyetheretherketone, a corresponding washing kettle needs to be used. Through the washing kettle, acetone washing and deionized water washing of polyetheretherketone can be carried out. However, some current washing kettles still have certain deficiencies in actual use. After acetone washing and deionized water washing of polyetheretherketone, different filter media are often needed to filter polyetheretherketone. However, some existing washing kettles often cannot conveniently carry out continuous acetone washing, deionized water washing, filtering, and drying treatment of polyetheretherketone, thereby increasing the overall processing complexity of polyetheretherketone, reducing the overall operation efficiency, and also increasing the overall operation burden of the staff. After retrieval, the patent document with the authorization announcement number CN213803587U discloses a washing kettle for preparing polyetheretherketone, which filters the polyetheretherketone after acetone washing and deionized water washing through different filters. However, it does not clearly state how to reset the filtered polyetheretherketone into the kettle body for subsequent operations, so there are still certain problems in its actual use.

[0004] In addition, when polyetheretherketone is filtered and washed, due to impurities such as unreacted monomers and oligomers, these impurity particles may block the pores of the sieve mesh, resulting in reduced filtration efficiency. Pure polyetheretherketone is relatively brittle, and there are problems such as easy blockage of the sieve mesh, complex operation, and short sieve mesh life due to the brittleness of polyetheretherketone.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present invention provides a washing kettle for preparing polyetheretherketone, as Figures 1-10 shown, the washing kettle for preparing polyetheretherketone includes: a washing box 1, the bottom of the washing box is provided with an outlet; a first washing chamber 2 and a second washing chamber 3 opened in the washing box 1 for washing polyetheretherketone with acetone and deionized water; two filtering chambers 4 opened on the washing box 1, one of the filtering chambers is located between the first washing chamber and the second washing chamber, and the other filtering chamber is opened between the second washing chamber and the outlet, and a first filter screen 5 and a second filter screen 6 for filtering the polyetheretherketone after acetone washing and deionized water washing are respectively arranged in the two filtering chambers 4; a drying box 7 fixedly installed at the bottom of the washing box 1 and communicated with the outlet for drying the washed polyetheretherketone, and a drying mechanism for drying the washed polyetheretherketone in the drying box 7 is arranged on the drying box 7; a stirring mechanism arranged on the washing box 1 for stirring the polyetheretherketone washed in the first washing chamber 2 and the second washing chamber 3.

[0021] In this embodiment, when washing polyetheretherketone, the corresponding raw materials are placed into the first washing chamber 2, and at the same time, a certain amount of acetone solution is placed into the first washing chamber 2. Meanwhile, the stirring mechanism is started, so that the polyetheretherketone and the acetone solution in the first washing chamber 2 can be fully contacted and mixed, thereby the polyetheretherketone can be washed with acetone. After the first batch of polyetheretherketone is washed with acetone, the washed polyetheretherketone together with the acetone is discharged into the filtering chamber 4 provided with a first filter screen 5 above the washing tank 1. Through the first filter screen 5, the polyetheretherketone and the acetone solution can be separated. At the same time, two collecting pipes are arranged on the washing tank 1, and the two collecting pipes are respectively communicated with the two filtering chambers 4. When filtering the washed polyetheretherketone, the corresponding collecting pipe needs to be opened. The collecting pipe is used for discharging and recycling the acetone and deionized water used for washing the polyetheretherketone. The polyetheretherketone remains on the first filter screen 5, and the acetone solution is discharged through the collecting pipe. Then the polyetheretherketone washed with acetone is discharged into the second washing chamber 3, and then a certain amount of deionized water is added into the second washing chamber 3. At the same time, the second batch of polyetheretherketone is placed into the first washing chamber 2 to wash the second batch of polyetheretherketone in the first washing chamber 2 with acetone. At this time, the stirring mechanism is started to respectively perform acetone washing and deionized water washing operations on the polyetheretherketone in the first washing chamber 2 and the polyetheretherketone in the second washing chamber 3. After the acetone washing and deionized water washing operations are respectively performed on the polyetheretherketone in the first washing chamber 2 and the polyetheretherketone in the second washing chamber 3, first, the polyetheretherketone washed with deionized water in the second washing chamber 3 is discharged into the filtering chamber 4 provided with a second filter screen 6. Through the second filter screen 6, the polyetheretherketone washed with deionized water can be filtered. The polyetheretherketone remains on the second filter screen 6, and the deionized water is discharged through the collecting pipe. Subsequently, the polyetheretherketone filtered on the second filter screen 6 is discharged into the drying box 7, and the washed polyetheretherketone is dried by the drying mechanism, and then the dried polyetheretherketone is discharged from the drying box 7. At the same time, the polyetheretherketone washed with acetone in the second batch in the first washing chamber 2 is discharged into the second washing chamber 3 for deionized water washing, and at the same time, the third batch of polyetheretherketone is continuously added into the first washing chamber for acetone washing, and so on. Thus, the polyetheretherketone of different batches can be continuously washed, and thus the acetone, deionized water washing, filtering and drying operations of the polyetheretherketone can be continuously performed, effectively reducing the complexity of washing the polyetheretherketone and improving the overall processing efficiency. Through the whole device, the acetone, deionized water washing, filtering and drying integrated operations of the polyetheretherketone can be carried out, effectively reducing the complexity of washing the polyetheretherketone and improving the overall processing efficiency.

[0023] Under normal conditions, several fan-shaped filters are placed at an angle, and the fan-shaped filters form a filter surface whose aperture is larger than that of the first filter. When polyetheretherketone falls in, the fan-shaped filter is pressed downward to apply pressure to the elastic connector, and the elastic connector rebounds under pressure, causing the fan-shaped filter to swing up and down periodically. After passing through the fan-shaped filter, it is filtered by the first filter, and the double-layer filtration prevents polyetheretherketone from clogging the filter. The process of the fan-shaped filter swinging downward is also a combing process for the polyetheretherketone gathered on the first filter, changing the aggregation state of the polyetheretherketone, and preventing the polyetheretherketone from clogging the first filter or damaging the first filter.

[0024] A dynamic screen assembly may also be provided on the second filter.

By starting the driving motor 9 through the controller to drive the mounting shaft 10 to rotate, under the mutual cooperation of the first bevel gears 11, synchronous pulleys 12 and synchronous belt 13, the two stirring frames 8 can be driven to rotate. The rotating stirring frames 8 respectively stir the polyether ether ketone in the first washing chamber 2 and the second washing chamber 3, so that the polyether ether ketone can be fully mixed and contacted with acetone solution and deionized water respectively, so as to fully wash the polyether ether ketone with acetone and deionized water and improve the washing effect of the polyether ether ketone.

[0029] In a further preferred embodiment of the present invention, two servo motors 14 are fixedly installed on an outer wall of the washing tank 1, and two placing shafts 15 are rotatably installed on the washing tank 1. The two placing shafts 15 are respectively fixedly connected to the first filter screen 5 and the second filter screen 6, and one ends of the two placing shafts 15 are respectively fixedly connected to output shafts of the two servo motors 14.

[0030] In this embodiment, when it is necessary to discharge the polyether ether ketone filtered on the first filter screen 5 and the second filter screen 6, the servo motor 14 is started through the controller to drive the placing shaft 15 to rotate, so that the first filter screen 5 and the second filter screen 6 can be turned over, and then the filtered polyether ether ketone can be unloaded, which is convenient for subsequent processing operations.

[0031] In a further preferred embodiment of the present invention, heating plates 16 are provided on both the washing tank 1 and the drying box 7, and the heating plates 16 are used to heat the polyether ether ketone in the first washing chamber 2, the second washing chamber 3 and the drying box 7.

[0034] In this embodiment, when drying the polyether ether ketone in the drying oven 7, the power motor 19 is started by the controller to drive the horizontal shaft 20 to rotate. Under the action of the second bevel gear 21, a plurality of stirring barrel rods 18 on the shaft tube 17 can be driven to rotate, so as to turn and stir the polyether ether ketone in the drying oven 7, thereby accelerating the drying efficiency of the polyether ether ketone. The protective shell can prevent the two second bevel gears from contacting the polyether ether ketone.

[0035] In a further preferred embodiment of the present invention, the drying mechanism includes: a blower 22 fixedly installed on an outer wall of one side of the drying oven 7; an air inlet pipe 23 fixedly installed on the outer wall of the drying oven 7, one end of the air inlet pipe 23 is communicated with the air outlet end of the blower 22, and the other end of the air inlet pipe 23 is hermetically and rotatably connected to the shaft tube 17; a plurality of air outlet openings 24 opened on the stirring barrel rods 18.

[0036] In this embodiment, when using the drying mechanism, the blower 22 is started by the controller. The air diverted by the blower 22 enters the shaft tube 17 through the air inlet pipe 23, and then is discharged into the drying oven 7 through the air outlet openings 24 on the stirring barrel rods 18, so as to dry the polyether ether ketone in the drying oven 7.

[0039] In a further preferred embodiment of the present invention, a feeding mechanism for feeding the polyether ether ketone in the drying box 7 is provided in the drying box 7. The feeding mechanism includes: a rectangular mounting frame 27 provided in the drying box 7 and surrounding the shaft tube 17 and a plurality of stirring barrel rods.

When the power motor 19 is started through the controller to drive the horizontal shaft 20 to rotate, the horizontal shaft 20 drives the convex block 29 to rotate. The continuously rotating convex block 29 periodically squeezes the mounting frame 27. When the mounting frame 27 is squeezed, the mounting frame 27 drives the feeding frame 28 to move downward, and the mounting frame 27 drives the slider 34 to move along the sliding rod 31. The slider 34 compresses the spring 32. When the convex block 29 does not squeeze the mounting frame 27, the spring 32 resets, so that the mounting frame 27 and the feeding frame 28 reset. Repeating this process, the feeding frame 28 continuously moves up and down, thereby further stirring the polyether ether ketone in the drying box 7, thereby improving the drying efficiency and uniformity of the polyether ether ketone.

[0042] In this embodiment, when discharging and filtering the polyether ether ketone after acetone washing in the first washing chamber 2, the collecting pipe on the filtering chamber 4 provided with the first filter screen 5 is opened, and at the same time, the elbow pipe 40 communicated with the filtering chamber 4 is opened, and the booster pump 38 is started. With the cooperation of the vertical pipe 39, the pressure in the first washing chamber 2 can be increased, so as to accelerate the filtering of the washed polyether ether ketone. Similarly, according to the above operation, when discharging and filtering the polyether ether ketone after deionized water washing in the second washing chamber 3, the filtering speed of the polyether ether ketone can be accelerated.

[0043] To sum up, compared with the related art, through the mutual cooperation of the first washing chamber 2, the second washing chamber 3, the first filter screen 5 and the second filter screen 6, the polyether ether ketone can be washed with acetone, then the polyether ether ketone after acetone washing can be filtered, then the polyether ether ketone can be washed with deionized water, and then the polyether ether ketone after deionized water washing can be filtered again.
