Description
Technical field
The utility model relates to a kind of bosh of plastic extruder.
Background technology
In the production of modified plastics, about 200 ℃, must just can enter pelletizing in the pelleter afterwards through the cooling hardening by the plastics material bar quality flexure temperature of extruding after the plastic extruder high-temperature fusion.And the tank that recirculated cooling water is housed a kind of cooling device that makes high-temperature fusion material bar cooling hardening that comes to this.
Existing plastic extruder bosh is the individual layer rectangular structure, and two ends, cell body bottom are offered water inlet and delivery port respectively, and water-in and water-out flow size is regulated by the water-in and water-out valve.The shortcoming of this tank is that water-in and water-out are separately control, is difficult to water-in and water-out speed is transferred in full accord, so liquid level is constantly to change in the tank, liquid level rising water can overflow tank, flows to the workshop; Liquid level reduces water and can drain off, and does not only have the effect to material bar cooling cooling, also can cause high temperature material bar to be wrapped on the conveying roller because of cooling off, a large amount of material bar bondings are deposited in the tank, the cleaning trouble not only hinders and produces, and brings very big loss, so someone keeps a close watch on level change constantly, utilize valve regulated Inlet and outlet water flow, complex operation not only, waste of manpower, also can influence ordinary production when serious, cause damage.
In actual production; cooling water flow has a significant impact cooling effect; inflow aniseed bar good cooling results, flow of inlet water small powder bar cooling effect is poor, if cool off insufficient; the material bar is not easy to be cut off in pelleter; the material bar that these can't cut not only can not use, and also can cause waste; stop up pelleter when serious, influence is produced.Cooling fully expects that bar is harder, is cut into granular easily.Existing plastic extruder bosh is regulated Inlet and outlet water flow size by valve, but Inlet and outlet water flow size can't be monitored during actual production.
The utility model content
The utility model is unstable and the material bar cooled off inadequate problem for solving existing plastic extruder bosh liquid level, provides that a kind of liquid level is constant, the water channel of plastic extrusion machine of good cooling results.
The utility model provides a kind of bosh of plastic extruder, and this tank comprises: tank body, water inlet and delivery port; Described tank body is a double-decker, comprises inner and outer wall, and inside and outside wall is in the end face connection and leave the uniform space of thickness between bottom surface and side, forms airtight interlayer; One end of inwall bottom surface offers water inlet; Two circular holes are offered at two ends, outer wall bottom surface, and one of them circular hole is corresponding with the inwall water inlet, and as the passage that leads to water inlet, the circular hole of the other end is as the delivery port of tank; On inwall, also offer some ostium excurrenses.
The plastic extruder bosh that the utility model provides, after cooling water flows into tank by water inlet pipe, at first be full of the inboard wall of cistern bottom, along with the inflow liquid level of cooling water constantly raises, when reaching bottom ostium excurrens place, cooling water just flows in the interlayer between the inside and outside wall, flows out tank from the delivery port that is arranged on the outer wall bottom again.When flow of inlet water big, the displacement of bottom ostium excurrens is during less than inflow, liquid level will rise and cover second layer ostium excurrens, thereby increase displacement, if the displacement of the first two layer ostium excurrens is still less than inflow, liquid level will rise and reach the 3rd layer of ostium excurrens place, three layers of ostium excurrens is set can guarantees that not the displacement deficiency causes cooling water to overflow tank when can be because of inflow very big, displacement up to ostium excurrens equates that with inflow it is constant that liquid level just keeps.If inflow reduces, liquid level will descend in the tank, and the displacement of ostium excurrens also can correspondingly reduce, and no longer descends just liquid level drops to bottom aperture place, equates with inflow up to displacement, and it is constant that liquid level keeps.Above-mentioned ostium excurrens rises or descends along with liquid level in the tank according to the size of inflow, and the size that can regulate displacement voluntarily makes liquid level keep constant to reach the purpose that equates with inflow.In actual production, can just can not produce overflow phenomena, and can not produce the problem that cooling water drains off in the tank yet smoothly by the delivery port outflow tank of outer wall bottom surface as long as guarantee the water that flows into interlayer between the inside and outside wall by ostium excurrens.The tank of this structure has solved existing plastic extruder bosh because the unequal liquid level that makes of Inlet and outlet water flow constantly changes the problem that causes overflow or cooling water to drain off, and has saved personal monitoring's process, has avoided the waste of manpower.Ostium excurrens has also played the filtration of the cooling water of convection current effluent trough simultaneously, has avoided impurity obstruction delivery port in the tank.
Under the preferable case, described ostium excurrens 5 is arranged on the top of inwall away from water inlet one end.Can guarantee that like this cooling water flows out from ostium excurrens after the whole tank of flowing through, improve the utilization rate of cooling water, make the cooling of material bar fully.
Under the preferable case, described ostium excurrens 5 is diameter equal-sized circular hole between 5-10mm.
Under the preferable case, described ostium excurrens divides three layers of setting, and interfloor distance is 1-2cm, and the quantity of every layer of aperture is 5-10.
Under the preferable case, the ostium excurrens of lowest part is 15-20cm apart from the distance of inboard wall of cistern bottom surface.
Under the preferable case, described tank is a rectangular structure, the long 4-4.5m of outer wall, and the wide 45-50cm of inwall, the inwall degree of depth is 30-35cm, outer wall and the inwall distance between side and bottom surface is 5cm.The too short meeting of the length of bosh makes the cooling of material bar insufficient, and excessive can taking again than large space reduced production efficiency.
Under the preferable case, circular hole 8 diameters of the water inlet 3 of described tank, delivery port 4 and outer wall bottom surface are 40mm.
Under the preferable case, the entery and delivery port of described tank is respectively equipped with flow of inlet water meter 6 and the water flow meter 7 that detects the discharge size.Can detect the flow situation of Inlet and outlet water at any time.Different plastic product experimental verifications is gone out best cooling water flow, can set different inflows to different plastic products in the actual production, product is cooled fully, can not cause the waste of water resource again.By the monitoring of flowmeter, equal inflow as long as guarantee water yield simultaneously, water just can not overflow tank.
