The working principle and the advantages of the invention are as follows: when the plastic pipe sizing and cooling production device is used, the working process is as follows:

as shown in fig. 1, cooling water is delivered into the cooling cylinder 2 through the water inlet pipe 10, water in the cooling cylinder 2 absorbs heat to the sizing pipe sleeve 1, and the water is discharged through the water outlet pipe 6 after being cooled, so that the plastic pipe is cooled.

In the above-mentioned process, water liquid in the inlet tube 10 drives reciprocating screw rod 15 through the impeller in the pump impeller 9 and rotates when flowing, make reciprocating screw rod 15 drive the ring plate 5 along reciprocating screw rod 15's length trend reciprocating linear motion, thereby make ring plate 5 drive ring brush 8 carry out real-time brushing to the incrustation scale on sizing pipe cover 1 lateral wall, thereby realize guaranteeing that the cooling effect is reliable and stable, avoid leading to the poor consequence that causes the plastic tubing production quality to reduce of cooling effect because of the incrustation scale is thick, and can reduce the requirement to quality of water, reduce the water cost, improve the economic nature, the incrustation scale sediment that is brushed off is discharged along with the rivers from outlet pipe 6 together.

As mentioned above, the cooperation water hole 7 makes the rivers in the cooling cylinder 2 mix at the in-process that the crown plate 5 removed, be convenient for improve the cooling efficiency to sizing pipe box 1, and the crown plate 5 makes gear 36 drive ring brush 8 through a worm 35 and a worm wheel 4 drive ring brush 8 to rotate under the effect of rack two 34 when driving gear 36 through a worm 35, realize that ring brush 8 carries out rotary motion in linear motion, thereby the more thorough incrustation scale to on the sizing pipe box 1 lateral wall brushes except, improve the efficiency and the effect of clean incrustation scale.

As shown in fig. 1, 3 and 4, the water liquid with scale slag discharged from the water outlet pipe 6 enters the filter cylinder 31, and is filtered by the filter plate 32 to separate the scale slag from the water liquid, so that the water liquid can be recycled, thereby improving the water saving and environmental protection effects, and the reciprocating linear motion of the ring plate 5 drives the slide bar 21 to move in a reciprocating linear motion together with the slide plate 18, so that the slide bar 21 drives the rack bar 25 to move in a reciprocating linear motion together with the link 24, and intermittently meshes and contacts with the outer ring of the ratchet 28 during the movement of the rack bar 25, and drives the outer ring of the ratchet 28 to rotate in a reciprocating manner, as shown in fig. 1, when the rack bar 25 moves left to drive the outer ring of the ratchet 28 to rotate clockwise, the outer ring of the ratchet 28 drives the inner ring to rotate, so that the inner ring of the ratchet 28 drives the rotating shaft 29 to rotate through the worm gear 39 and the worm gear 38, and then make pivot 29 drive filter 32 rotate clockwise in figure 4, the relative scraper blade 33 of filter 32 pivoted in-process moves, make the incrustation scale sediment on the filter 32 collect in gathering dirty box 42 through sediment section of thick bamboo 40 under the effect of scraper blade 33, realize the collection to the incrustation scale sediment, avoid the incrustation scale sediment to pile up on filter 32, and the incrustation scale sediment that gathers dirty box 42 that transparent material made is convenient for observe and gathers dirty box 42 is piled up fully, if full, close control valve 41 earlier, then will gather dirty box 42 and take off the incrustation scale sediment of clean inside, again will empty the back gather dirty box 42 and adorn on sediment section of thick bamboo 40, then open control valve 41, thereby realize the clearance to the incrustation scale sediment, easy operation is convenient.

When the first rack 25 moves rightwards to drive the outer ring of the ratchet 28 to rotate anticlockwise in fig. 1, the outer ring of the ratchet 28 cannot drive the inner ring to rotate, so that the inner ring of the ratchet 28 cannot drive the filter plate 32 to rotate anticlockwise in fig. 4, the scale slag is prevented from being accumulated on one side of the scraper 33, which deviates from the interface between the slag discharge barrel 40 and the filter cylinder 31, and the scale slag can be discharged smoothly.

As shown in figure 1, the connecting rod 24 drives the piston plate 19 to move left and right in the pump cylinder 17 in a reciprocating manner through the sliding rod two 20 while the sliding rod one 21 drives the connecting rod 24 to move in a reciprocating manner, so that the piston plate 19 applies a compression force or a suction force to the spaces on both sides of the piston plate in an alternating manner, namely, one side of the piston plate 19 receives the compression force and the other side receives the suction force, because the conduction direction of the check valve one 11 points to the inside of the pump cylinder 17, and the conduction direction of the check valve two 14 points to the nozzle 30, so that the water liquid in the pump cylinder 17 is conveyed to the nozzle 30 through the water pipe two 13 and is sprayed out from the bottom surface of the filter plate 32 through the nozzle 30, thereby the scale slag blocked in the filter holes of the filter plate 32 is flushed out by the water flow, on one hand, the filter plate 32 is ensured to be kept smooth, the filtering efficiency and the effect are improved, on the other hand, the flushing is carried out from the lower surface of the filter plate 32, and the flushed out scale slag is prevented from being discharged from the drainage elbow 27, the separation effect of scale slag and water liquid is improved, and when suction force is applied to one side of the piston plate 19, the water liquid with filter residues removed in the water storage box 23 is sucked into the pump barrel 17 through the first water pipe 12, so that automatic water replenishing is realized.
