Description

Technical Field

[0001] The utility model relates to the technical field of cooling water tanks, in particular to a cooling water tank for an outer coating extruder. Background Art

[0002] During the processing of the plastic extruder, the pipe extruded from the extruder die needs to be cooled by cooling water. At present, the cooling of the pipe is carried out by tap water cooling. The tap water enters the cooling water tank through the water inlet valve from the water inlet of the cooling water tank. After the pipe cooling cycle, it flows out from the overflow port of the cooling water tank and is discharged through the outlet.

[0003] However, the existing outer coating extruder pipe is cooled by a mobile pre-cooling box (6 meters) and two spray cooling boxes (9 meters each), which has the disadvantages of insufficient cooling of large-diameter pipes with thick outer coatings, rough pipe surfaces, a large number of cooling boxes and a long production line distance. Utility Model Content

[0004] The utility model aims to provide a cooling water tank for an outer coating extruder to solve one or more of the above-mentioned prior art problems.

[0005] The utility model provides a cooling water tank for an outer coating extruder, comprising:

[0006] The water tank body is a rectangular open structure, including a bottom plate and four side walls: front, rear, left and right;

[0013] In certain embodiments, the water stop gate plate includes a central perforation of the gate plate, and the material of the central perforation of the gate plate is silicone, which can form a seal with the pipe.

[0014] In certain embodiments, one side of the two circulating overflow water collection tanks away from the water stop gate plate is U-shaped.

[0015] In some embodiments, the sink body further includes a base support.

[0016] In certain embodiments, the base support is provided with a height-adjustable foot cup.

[0017] Beneficial effects: The utility model has a simple structure. By setting a water tray, it can collect the pre-spray water of the pipe and the splashing water at the water tank entrance; by setting a water inlet at the bottom of the water tank and configuring a guide cover plate at the water inlet, it can form a fast water flow, and the water flow baffle can block the fast water flow, so that the cooling water forms sufficient convection during the flow of the water tank, thereby realizing rapid cooling of large-diameter pipes.

[0022] like Figure 1-2 As shown, a cooling water tank for an outer coating extruder includes: a water tank body 1, a hand-cranked spiral lifting nylon roller 2, a water tray 3, a water stop gate 4, a circulating overflow water collection tank 5 and a base bracket 6.

[0023] Specifically, the water tank body 1 is a rectangular open structure, including a bottom plate 11 and four side walls at the front, rear, left and right sides; a hand-cranked spiral lifting nylon roller 2 is arranged inside the water tank body 1, and the number of hand-cranked spiral lifting nylon rollers 2 is multiple, and the multiple hand-cranked spiral lifting nylon rollers 2 are arranged along the length direction of the water tank body 1; a water tray 3 is provided on the left side of the water tank body 1, and the height of the water tray 3 is set lower than the bottom surface of the water tank body 1; a water stop gate 4 is provided at the left and right ends of the water tank body 1.

[0025] The water-stop gate plate 4 includes a gate plate central through hole 41 , and the material of the gate plate central through hole 41 is silicone, thereby being able to form a seal with the pipe.

[0026] The two circulating overflow water collecting tanks 5 have one side away from the water stop gate plate 4 in a U-shape, which is consistent with the shape of the pipe and can just accommodate the pipe.

[0027] The sink body 1 further includes a base bracket 6 , on which a height-adjustable foot cup 61 is provided.

[0028] like Figure 2 As shown, a cooling water trough of an outer coating extruder is shown, wherein a bottom plate 11 thereof is provided with a plurality of water inlets 111 , and the water inlets 111 are provided with guide covers 112 .

[0029] Specifically, the water tank body 1 is a rectangular open structure, including a bottom plate 11 and four side walls at the front, rear, left and right sides; a hand-cranked spiral lifting nylon roller 2 is arranged inside the water tank body 1, and the number of hand-cranked spiral lifting nylon rollers 2 is multiple, and the multiple hand-cranked spiral lifting nylon rollers 2 are arranged along the length direction of the water tank body 1; a water tray 3 is provided on the left side of the water tank body 1, and the height of the water tray 3 is set lower than the bottom surface of the water tank body 1; a water stop gate 4 is provided at the left and right ends of the water tank body 1.

[0030] Working principle: When the outer sheathed pipe is produced by the extruder, a large amount of pressure-free water is poured directly on the surface of the pipe, which is then collected in the water tray and sent to the return water main line. After the pipe passes through the water stop gate and the water tank body, the water inlet valve is opened, the water tank is quickly filled and the rollers are adjusted to make the pipes on the same horizontal plane. After the liquid level is higher than the water stop gate, it overflows to the water tanks at both ends. The entire pipe is completely immersed in the circulating cooling water. Cooling water with a lower temperature is continuously injected into the bottom of the water tank, and water with a higher temperature at the top of the water tank overflows into the return water cooling system to maintain the water temperature of the water tank within a certain range.

[0031] In summary: the utility model has a simple structure. By setting a water tray, it can collect the pre-spray water of the pipe and the splashing water at the water tank entrance; by setting a water inlet at the bottom of the water tank and configuring a guide cover plate at the water inlet, it can form a fast water flow, and the water flow baffle can block the fast water flow, so that the cooling water forms sufficient convection during the flow of the water tank, thereby realizing rapid cooling of large-diameter pipes. The cooling water tank of the outer coating extruder can shorten the length of the production line and reduce the equipment cost.
