Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, and in particular to a water washing filter for polyether ether ketone (PEEK) production. Background Technology
[0002] Polyetheretherketone (PEEK) is a high-performance thermoplastic polymer that is widely used in aerospace, medical devices, electronics and automotive industries due to its excellent high temperature resistance, chemical corrosion resistance, mechanical strength and biocompatibility.
[0003] In its production process, water washing and filtration are key purification steps, directly affecting the purity and performance of the final product. Common filtration equipment can be categorized as follows:
[0004] Plate and frame filter press: It separates solids and liquids by pressure and is suitable for systems with high solid content, but the operation cycle is long and the cleaning is complicated.
[0005] Centrifuges: They use centrifugal force to separate solids and liquids. They are highly efficient, but they consume a lot of energy and are prone to fine powder loss.
[0006] Vacuum drum filter: continuous operation, suitable for large-scale production, but poor adaptability to viscous materials.
[0007] Membrane filtration systems: used for fine filtration, capable of trapping nano-sized particles, but membrane fouling is a prominent problem.
[0008] Traditional equipment struggles to achieve multi-stage countercurrent washing, resulting in high water consumption and wastewater treatment costs. Excessive manual intervention leads to poor batch-to-batch consistency and hinders continuous production, thus impacting product quality stability. Utility Model Content
[0009] To address the problems mentioned in the background section, this invention provides a water washing filter for polyether ether ketone (PEEK) production.
[0010] To achieve the above objectives, the present invention adopts the following technical solution:

The water washing cylinder is located inside the outer vessel body. A feeding component is provided at the upper end of the water washing cylinder. A water washing spray pipe is vertically inserted into the feeding component. An annular spray pipe is provided on the outer wall of the end of the water washing spray pipe that extends into the water washing cylinder. The annular spray pipe is connected to the washing spray pipe through several sets of connecting pipes. Several sets of nozzles are distributed around the upper end face of the annular spray pipe.
[0012] The circumferential sidewall of the washing drum is provided with a filter screen, and the outer walls of the washing spray pipe are fixedly connected to a cleaning scraper and a cleaning brush by support rods. The outer wall of the washing spray pipe is also provided with a spray hole, which is connected to the washing spray pipe.
[0013] The bottom of the outer vessel is connected to a washing water discharge port, and the bottom of the washing drum is connected to a material discharge port, which extends downward through the washing water discharge port.
[0014] Preferably, the feeding component is composed of an upper inlet, a middle inlet and a lower inlet connected sequentially from top to bottom. The outer wall of the water washing spray pipe and located inside the middle inlet is provided with a clearing block. The length of the clearing block is less than the gap between the water washing spray pipe and the inner wall of the middle inlet. By setting the clearing block, the material accumulated in the feeding component can be cleared and scraped away to avoid material blockage.
[0015] The diameters of both the upper and lower inlets are larger than those of the middle inlet. On the one hand, the upper inlet facilitates material feeding, and on the other hand, the material is gathered through the middle inlet and then dispersed through the lower inlet, thus facilitating the dispersion and washing of the material by the annular nozzle.
[0016] Preferably, the water washing spray pipe has a water inlet pipe at the upward extension end through the water washing cylinder, and a bearing is provided at the connection between the water inlet pipe and the water washing spray pipe.
[0017] Preferably, the water washing spray pipe extends through the outer wall of the upward-extending end of the water washing cylinder and is fitted with a first gear. A second gear is meshed with one side of the first gear. The inner wall of the second gear is connected to a first motor via a rotating shaft. The first motor is located on one side of the upper end of the outer vessel body.
[0018] Preferably, the upper and lower ends of the inner wall of the outer vessel are respectively provided with fixed limiting components.
[0019] Preferably, a large gear is sleeved on the upper outer wall of the washing drum. The large gear is limited by a fixed limiting component, and a small gear is meshed with one side of the large gear. The small gear is connected to a second motor through a rotating shaft. The second motor is located on one side of the outer wall of the outer vessel.
[0020] Preferably, an annular limiting slider is sleeved on the lower outer wall of the washing drum, and the annular limiting slider is limited by a fixed limiting component.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. The diameters of the upper and lower inlets of this utility model are larger than those of the middle inlet. On the one hand, the upper inlet facilitates the feeding of materials, and after being gathered by the middle inlet, the materials are dispersed by the lower inlet. This allows the annular spray pipe located directly below the lower inlet to disperse and wash the materials, thereby improving the washing efficiency and quality.
[0023] 2. This utility model is also provided with spray holes, which can spray and wash the material adhering to the inner wall of the washing drum, thereby increasing the washing area. The material adhering to the inner wall of the washing drum is scraped off by the cleaning scraper, and the cleaning brush can clean it.
[0024] 3. This utility model integrates water washing and filtration into a single structure, thereby enabling continuous processing of crude polyether ether ketone (PEEK) products, avoiding the waste of space and time occupied by multiple equipment, and has high social value and application prospects.

The annular spray pipe 6 is connected to the water washing spray pipe 5 through several sets of connecting pipes 62. Several sets of nozzles 61 are distributed around the upper end face of the annular spray pipe 6.
[0033] The circumferential sidewall of the washing drum 2 is provided with a filter screen 3, and the outer walls of the washing spray pipe 5 are fixedly connected to the cleaning scraper 7 and the cleaning brush 8 by support rods. The outer wall of the washing spray pipe 5 is also provided with a spray hole 9, which is connected to the washing spray pipe 5.
[0034] The bottom of the outer vessel 1 is connected to a washing water discharge port 16, and the bottom of the washing drum 2 is connected to a feeding port 15, which extends downward through the washing water discharge port 16.
[0035] The feeding component 4 is composed of an upper inlet 41, a middle inlet 42 and a lower inlet 43 connected from top to bottom. The outer wall of the water washing spray pipe 5 and located inside the middle inlet 42 is provided with a clearing block 51. The length of the clearing block 51 is less than the gap between the water washing spray pipe 5 and the inner wall of the middle inlet 42. By setting the clearing block 51, the material accumulated in the feeding component 4 can be cleared and scraped away to avoid material blockage.
[0036] The diameters of the upper inlet 41 and the lower inlet 43 are both larger than those of the middle inlet 42. On the one hand, the upper inlet 41 facilitates the feeding of materials, and after being gathered by the middle inlet 42, the materials are dispersed by the lower inlet 43, thus facilitating the dispersion and washing of the materials by the annular nozzle 6.
[0037] The water washing nozzle 5 extends upward through the water washing cylinder 2 and is provided with a water inlet pipe 52. A bearing is provided at the connection between the water inlet pipe 52 and the water washing nozzle 5.
[0038] The water washing nozzle 5 extends through the outer wall of the water washing cylinder 2 and is fitted with a first gear 53. A second gear 54 is meshed with one side of the first gear 53. A first motor 55 is connected to the inner wall of the second gear 54 through a rotating shaft. The first motor 55 is located on one side of the upper end of the outer vessel body 1.

[0041] The lower outer wall of the washing drum 2 is fitted with an annular limiting slider 14, which is limited by the fixed limiting component 10.
[0042] Working principle: The crude PEEK product to be washed enters the middle inlet 42 through the upper inlet 41, and then enters the washing drum 2 through the lower inlet 43. At this time, the washing water enters the washing spray pipe 5 through the water inlet pipe 52. Since the annular spray pipe 6 is located directly below the lower inlet 43, it can spray water to wash the dispersed crude product. After a period of time, the first motor 55 is started. The first motor 55 drives the washing spray pipe 5 to rotate through the second gear 54 and the first gear 53.
[0043] The water washing nozzle 5 drives the spray holes 9 on the side wall to wash and rinse the coarse product, thereby washing and dissolving its impurities. The cleaning scraper 7 can scrape off the material adhering to the inner wall of the water washing drum 2, while the cleaning brush 8 can clean it.
[0044] The second motor 13 is started. The second motor 13 drives the washing drum 2 to rotate through the small gear 12 and the large gear 11, thereby realizing the centrifugal dehydration of the washing drum 2. The washing wastewater enters the outer vessel 1 through the filter screen 3 and is discharged outward through the washing water outlet 16. The PEEK after washing and filtration is collected through the discharge port 15.
