Description

Jet flow cooling device with adjustable liquid level

Technical Field

The utility model relates to a modified production field of fine reinforcing thermoplastic of long glass especially relates to a liquid height adjustable jet cooling device.

Background

In the modified production of long glass fiber reinforced thermoplastic at present, the basin that length was about 3 ~ 6 meters is all adopted in most coolings to cool off, but the demand of the product of different glass fiber content to the cooling is very different, the not enough or excessive poor consequence that all causes of cooling, the not enough phenomenon of hanging that can cause the resin to drip of cooling, probably several lines in near place glue together, product appearance quality is very poor, the too high damage to cutting the grain sword is great to cutting the grain simultaneously, too much also bring the difficulty to follow-up cutting the grain of cooling, the moisture content of product can't be controlled simultaneously, simultaneously because the cooling is not enough, often can satisfy the technological requirement through reduction of production. Because the glass fiber content span is large and ranges from 20% to 60%, if a water tank with a fixed size and a fixed cooling process are adopted to produce products with all glass fiber contents, the difficulty is very high, and the process is difficult to control. Thus, a special cooling device is needed to meet the production process of the ultra-long glass fiber reinforced thermoplastic modification with different glass fiber contents.

The length of the existing water tank is 3-6 meters, and although the water inlet depth and the length can be adjusted, the problems of inconvenient adjustment, poor reliability and the like still exist. More importantly, when the content of the produced glass fiber is less than 40%, the plastic attached to the surface of the glass fiber is large, if the glass fiber is not cooled in time, the dripping and hanging phenomenon is caused immediately, and a distance is reserved between the foremost end of a common water tank and a plastic line outlet of a mold, so that the dripping and hanging phenomenon is avoided, and the product particle type cannot meet the requirements of customers. Or, in order to ensure the qualified product surface quality, the production speed is reduced, so that the equipment cannot reach the designed capacity, and the production efficiency of the equipment is greatly reduced.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, an embodiment of the present invention includes:

a spray cooling device with adjustable liquid level, comprising: cooling bath 4 and return water tank 5, return water tank 5 sets up in cooling bath 4 both sides the bottom of cooling bath 4 evenly is connected with five spray pipes 3, and these five spray pipes 3 are connected in bottom water knockout drum 2, water knockout drum 2 is connected to the system water tank through total water inlet 1 the 3 mouth of pipe of every spray pipe correspond the department and be provided with breakwater 41 respectively in cooling bath 4, breakwater 41 is fixed to be set up in cooling bath 4. A water baffle 41 is arranged at the upper end of the nozzle of each spray pipe 3, so that the water column at the position of the spray pipe 3 is prevented from being sprayed too high, and the water column at the position far away from the spray pipe 3 is prevented from being low.

Further, each spray pipe 3 is provided with a flow control valve 31, and the flow control valve 31 is a ball valve. By adjusting the flow regulating valve 31 of the five water spraying pipes and under the combined action of the water baffle 41, the whole liquid level is uniform and flat, and one high position and one low position cannot occur, so that each long glass fiber modified plastic brace can be soaked in water.

Further, a filter screen 51 is arranged in the water return tank 5, the filter screen 51 covers the cross section of the whole water return tank 5, water in the water return tank 5 can be filtered, and the filtered water flows back to the system water tank through a water return port 52 at the bottom of the water return tank.

Further, the height of the side wall of the water return tank 5 is slightly lower than that of the side wall of the cooling tank 4. The water column overflows from two sides, water is discharged into a water tank of a cooling system through a water return tank 5, water in the water tank is subjected to the action of a water pump to establish certain pressure and flow, the water is cooled through a heat exchanger, the other loop is connected with a water cooler (the process is not in the content of the invention), cooling water with reduced temperature is continuously supplied to a jet flow cooling water tank to cool 100 long glass fiber modified plastic braces, and the operation is repeated.

The utility model discloses being close to the export of mould plastics lines, arrange a subminiature, the liquid level longitudinal length only 200 millimeters, liquid level height-adjustable's jet cooling device, this device lets the fine thermoplastic modified plastics brace of overlength glass come out and just begin to cool off, make and drip and hang the phenomenon and stop completely, according to the difference of the fine content of glass, the height of adjustable liquid level and the temperature of cooling water, both realize the fine thermoplastic modified plastics brace of overlength glass completely reliably and do not appear dripping and hang the phenomenon, fine outward appearance cladding thickness all around of glass is even, can not appear again because the cooling excessively causes the condition that the moisture content is on the high side. The glass fiber thermoplastic reinforced plastic composite material can be suitable for producing products with different glass fiber contents and ultra-long glass fiber thermoplastic reinforced plastic modification, various difficulties and inconvenience encountered by product switching are avoided, the flexibility of a production line is greatly improved, a designed cooling device is exquisite and small, adjustment and maintenance are convenient, the cooling of braces is further conveniently controlled, and the production efficiency and the product quality are improved.
