Description

Temperature control circulating cooling and controlling water tank for cable extrusion coating

Technical Field

The utility model belongs to the technical field of cable manufacturing, and particularly relates to a temperature-controlled circulating cooling and controlling water tank for a cable extrusion coating.

Background

The cable has very wide application in modern industrial systems, the center of the cable is provided with a guide core made of metal materials such as copper and aluminum, and the outside of the cable is provided with a wrapping layer, so that the cable plays roles of insulation and wear resistance. In the production process of the cable, the wrapping layer is mainly solidified outside the guide core by adopting an extrusion process at present. One of the technical cores of the process is that the wrapping layer on the guide core is gradually cooled through the water tank until the wrapping layer is solidified and molded along with the forward traction of the cable. However, this process currently has some drawbacks, such as: the wrapping layer is easy to scratch when passing through the water tank; the curing strength of the wrapping layer is influenced by overlarge temperature difference at the initial cooling stage; the water consumption of the water tank is large, and the waste is serious.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a temperature-control circulating cooling and controlling water tank for a cable extrusion coating layer.

The technical scheme of the utility model is that the temperature-control circulating cooling and temperature-control water tank for the cable extrusion coating layer comprises a tank body, an atomization spraying frame and a water circulating device; the whole tank body is in a long strip shape, one end of the tank body is provided with an inlet for leading in a cable, and the other end of the tank body is provided with an outlet for leading out the cable; the bottom plate of the tank body is a smooth curved surface, the two ends are high, the middle is low, water can be conveniently contained, and the cable is prevented from being scratched when passing through the tank body; an atomization spraying frame is arranged in the groove body and close to the inlet; a water outlet is arranged on the bottom plate of the tank body near the outlet; the water circulating device is connected between the water outlet and the atomization spraying frame, and the water flowing out of the water outlet is cooled and then conveyed to the atomization spraying frame to be sprayed out.

For convenience of description, the following are defined as the directions to which the present invention relates: the direction from the inlet to the outlet is denoted forward and the opposite direction is denoted backward.

The utility model is arranged at the extrusion outlet of the extruder during operation. After being led out from an extrusion port of the extruder, the cable enters the groove body through the inlet and moves forwards along the groove body to the outlet to be led out. In the process that the cable advances in the cell body, carry out primary cooling through atomizing spray frame earlier, then move along the cell body bottom plate forward, draw from the export after further cooling under the soaking of cooling water. The water mist sprayed by the atomization spraying frame is collected at the bottom of the groove body after contacting the cable for the first time, a cooling water body with a fixed depth is formed at the bottom of the groove body, and along with continuous spraying of the water mist, the cooling water body is accumulated continuously, finally overflows from the water outlet and enters the water circulation device to be recycled after cooling. Therefore, the cable is cooled step by step through water mist cooling and water body cooling, the cable is prevented from directly entering the water body to be rapidly cooled to influence strength, and in addition, water can be greatly saved through a cooling water circulation mode.

Further, the water circulation device comprises a water tank, a water collecting port, a water supply port, a water delivery pump and a coolant pipe; the top of the water tank is provided with a water collecting port connected with a water outlet, the bottom of the water tank is provided with a water supply port connected with a suction inlet of a water delivery pump, and an output port of the water delivery pump is connected with an atomizing spray frame; the coolant pipe is arranged in the water tank and is positioned at the lower part of the water tank. Preferably, the water circulation device adopts a sinking type arrangement mode or the water tank adopts a heightening type arrangement mode, so that cooling water overflowing from the water outlet naturally flows into the water collecting opening, and an additional lifting pump is avoided. The coolant, such as chilled brine, flows through the coolant pipe to cool the water in the water tank, and the cooling water is recycled.

Further, a temperature sensor is also arranged in the water tank. The temperature sensor monitors the temperature of the water body in the water tank, provides basis for regulating the flow of the coolant, increases the flow of the coolant when the temperature is too high, and reduces the flow of the coolant when the temperature is too low.

Furthermore, a water replenishing port is also arranged at the top of the water tank. As the cable continuously advances forwards, a small amount of water drops attached to the surface of the cable are continuously taken away, so that the total amount of cooling water is slowly reduced. The cooling water can be supplemented to the water tank through the water supplementing opening to maintain the basic stability of the cooling water quantity, and the cooling water can be supplemented in an intermittent mode or a continuous mode.

Furthermore, the atomization spray frame comprises a main pipe positioned above the tank body, a group of branch pipes which are distributed at intervals along the main pipe and extend downwards to enter the tank body, and an atomization spray head connected to the tail ends of the branch pipes; the main pipe is connected with the output port of the water delivery pump.

Furthermore, the atomizing spray head comprises a spray cap covering the tail end of the branch pipe, a first spray nozzle fixed on the spray cap and a group of second spray nozzles; the first nozzle is located in the center of the bottom surface of the spray cap and sprays water mist to the right lower direction, and the group of second nozzles are distributed around the first nozzle and spray water mist downwards in an inclined mode, so that dispersed water mist is formed in a space range close to an inlet in the tank body, and the cable is cooled more softly.

Further, spout the cap inner wall and be equipped with the internal thread, the branch pipe end is equipped with the external screw thread, spouts cap screw thread ground connection at the branch pipe end. The threaded fit connection is convenient to detach, so that the atomizing nozzle can be replaced when the nozzle is blocked.

Further, a section of the groove body bottom plate positioned at the outlet is marked as an outlet guide section; the outlet guide section is smoothly lifted upwards and then is arc-shaped and turned downwards from back to front. The guide section has two main functions: firstly, the guide cable is gradually lifted and completely separated from the cooling water body, so that the loss of the cooling water is reduced; and secondly, the cable is guided to leave the groove body, so that the cable is prevented from contacting a sharp part of the groove body to cause scratch when leaving.

Has the advantages that: compared with the prior art, the temperature control circulating cooling temperature control water tank for the cable extrusion coating layer is reasonable in structure, simple to operate and economical in cost, can cool the cable extrusion coating layer step by step in a softer mode, can effectively avoid cable scratches, and can effectively save cooling water.
