Technical Field

[0001] This utility model relates to the field of plastic pipe technology, and in particular to a filtration and impurity removal device for plastic pipe production. Background Technology

[0002] During the production of plastic pipes, the raw materials are melted into a molten state and then injected into an extruder for molding. However, the raw materials may contain impurities, which need to be filtered and removed before entering the extruder. Due to the nature of the molten raw materials, the filter screen is easily clogged when impurities are attached to it. Therefore, the filter screen needs to be cleaned frequently to ensure filtration efficiency. This will cause repetitive and ineffective work and seriously affect the production schedule.

A filtration mechanism is provided on the machine body near the discharge outlet. The filtration mechanism includes a slide groove perpendicular to the axis of the machine body. A filter plate is slidably arranged in the slide groove. The filter plate has an oblong structure and two filter screens are respectively provided at both ends. When the filter plate slides to one end in the slide groove, the filter screen on the other side of the filter plate is aligned with the machine body.

[0005] Preferably, the filter plate slides and seals within the groove, and there is no leakage after the filter screen is aligned with the machine body.

[0006] Preferably, the slide groove has through holes at both ends, and the through holes are matched with the size of the filter screen. When one filter screen is aligned with the machine body, the other filter screen is aligned with the through hole.

[0007] Preferably, the slide groove is provided with hydraulic cylinders at both ends, and the extension rods of the two hydraulic cylinders are respectively connected to the two ends of the filter plate.

[0008] Preferably, the filter screen has a baffle in the middle, which divides the filter screen into two semi-circular structures.

[0009] This utility model has a simple and ingenious structure and is easy to use. When the filter efficiency decreases, it can quickly switch to replace the working filter, maintain the filter efficiency, and ensure the smooth operation of production. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 5 It is known that a filtration and impurity removal device for plastic pipe production includes a body 1, which is in the shape of a circular pipe. A feed inlet 2 is provided at one end of the body 1, and a discharge outlet 3 is provided at the other end of the body 1. A filtration mechanism is provided on the body 1 near the discharge outlet 3. The filtration mechanism includes a slide groove 4 perpendicular to the axis of the body 1. A filter plate 5 is slidably arranged in the slide groove 4. The filter plate 5 has an oblong structure and two filter screens 6 are respectively provided at both ends. When the filter plate 5 slides to one end in the slide groove 4, the filter screen 6 on the other side of the filter plate 5 is aligned with the body 1.

[0017] In practical use, this utility model Connect the discharge port 3 of this device to the extruder inlet and the feed port 2 to the material tank. Molten material enters the machine body 1 and then enters the extruder after passing through the filter screen 6. The filter screen 6 filters and removes impurities from the material. When there are many impurities on the filter screen 6 and it needs to be cleaned, quickly switch the working filter screen 6, move the used filter screen 6 to the outside, and replace it with a new filter screen 6. The filter screen 6 is switched quickly without affecting the production progress. Then, clean the used filter screen 6 from the outside without affecting the smooth operation of production.

[0018] The filter plate 5 slides and seals within the groove 4, and the filter screen 6 is aligned with the machine body 1 without leakage, thus avoiding material loss.

[0019] The slide 4 has through holes 7 at both ends, and the through holes 7 are matched with the size of the filter screen 6. When one filter screen 6 is aligned with the machine body 1, the other filter screen 6 is aligned with the through hole 7. The slide 4 has hydraulic cylinders 8 at both ends, and the extension rods of the two hydraulic cylinders 8 are respectively connected to the two ends of the filter plate 5. The filter screen 6 has a baffle 9 in the middle, which divides the filter screen 6 into two semi-circular structures.

[0020] When switching the filter screen 6, the hydraulic cylinder 8 pushes the filter plate 5 to move in the slide groove 4, and the filter screen 6 is offset from the machine body 1. At this time, the baffle 9 plays a blocking role to prevent the machine body 1, the filter screen 6 and the discharge port 3 from forming a sealed state, and will not connect to the through hole 7, thus preventing material leakage and external impurities from entering the machine body 1 and contaminating the material.

[0021] The baffle 9 can both block the filter screen 6 and increase its strength, preventing damage and extending the service life of the equipment.

[0022] The filter screen 6 and the filter plate 5 are detachably connected. When the filter screen 6 can no longer meet the filtration requirements after cleaning, the filter screen 6 can be removed and replaced with a new filter screen 6. The filter screen 6 and the filter plate 5 can be connected by screws. The screws should not protrude beyond the surface of the filter plate 5 and should not affect the seal between the filter plate 5 and the slide groove 4.

[0023] A conveying power device, such as a fluid pump, needs to be installed between the machine body 1 and the material tank to apply pressure to the material and make it enter the extruder quickly.

[0024] When the filter screen 6 is removed from the machine body 1, it will bring out a certain amount of material. Two collection boxes can be set on both sides of the through hole 7 to collect the filtered material and the unfiltered material respectively. Since the unfiltered material contains a lot of impurities, it can be disposed of as waste. The filtered material can be protected and put into the extruder for use to avoid waste.

[0025] Compared with the prior art, this utility model has the following advantages: it can quickly replace the filter screen, shorten downtime, and thus improve filtration efficiency.
