Description

Technical Field

[0001] This application relates to the technical field of wire drawing machines for water tanks, and particularly to a device for recycling waste heat from circulating water based on a wire drawing water tank. Background Art

[0002] A wire drawing machine for a water tank is a device used for the drawing process of metal wire rods. Through mechanical force, the metal wire rods are drawn step by step to reduce their diameter and increase their length. The working principle of the wire drawing machine for a water tank is to place multiple drawing heads in the water tank, and through step-by-step drawing, the metal wire rods reach the required specifications. During the multiple drawing processes, due to heat generated by friction, the liquid in the water tank will continuously circulate to cool and lubricate the wire rods to prevent the temperature from being too high during the drawing process and affecting the product quality. The cooling water in the water tank has good value for waste heat recycling.

[0003] By recovering and utilizing the waste heat of the circulating water in the wire drawing water tank, the dependence on external energy can be reduced, and energy consumption and carbon emissions can be lowered. Preheating the metal wire rods with the waste heat of the circulating water in the wire drawing water tank can reduce the thermal stress during the wire drawing process, help the metal wire rods maintain appropriate plasticity and toughness during the wire drawing process, improve the mechanical properties and surface quality of the wire rods, and thus improve production efficiency and product quality.

[0025] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, rather than limiting the application. Additionally, it should be noted that for the sake of description, only the parts related to the application are shown in the accompanying drawings.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figure 1 , an embodiment of the present application provides a circulating water waste heat reuse device based on a wire drawing water tank, including a plate heat exchanger 1, a water tank 2 and a preheating mechanism 3;

[0028] One end of the plate heat exchanger 1 in the length direction is respectively provided with a first water inlet 11, a first water outlet 12, a second water inlet 13 and a second water outlet 14; a first water inlet pipe 21 and a first water outlet pipe 22 are respectively and communicatively arranged at the first water inlet 11 and the first water outlet 12; both the first water inlet pipe 21 and the first water outlet pipe 22 are communicated with the wire drawing water tank;

[0029] A second water inlet pipe 23 is communicatively arranged at the second water inlet 13; the second water outlet 14 is communicatively arranged with the water tank 2 through a pipeline; one end of the water tank 2 far from the second water outlet 14 along the axial direction is communicatively arranged with a second water outlet pipe 24;

[0030] The preheating mechanism 3 includes a spiral pipe 31, a total water inlet pipe 32 and a total water outlet pipe 33.

[0031] In this embodiment, the plate heat exchanger 1 is formed by pressing thin metal plates into corrugated heat exchange plates, and then stacking these plates and fastening them with clamping plates and bolts. In the plate heat exchanger 1, the cold and hot fluids flow relatively through flow channels in different directions, thereby realizing heat transfer and heat exchange.

[0032] The present application connects the high-temperature liquid in the wire drawing water tank to the plate heat exchanger 1 through the first water inlet 11 via the first water inlet pipe 21, and reflows it back to the wire drawing water tank through the first water outlet 12 via the first water outlet pipe 22. The high-temperature liquid in the wire drawing water tank transfers heat through the plate heat exchanger 1, so that the waste heat of the circulating water in the wire drawing water tank is fully utilized, and at the same time, the temperature of the liquid in the wire drawing water tank is reduced, effectively cooling the metal wire during the stretching process.

[0033] In a preferred embodiment, the spiral pipe 31 is arranged as a spiral pipe; both ends of the spiral pipe 31 in the pipe direction are respectively and communicatively provided with a water inlet 34 and a water outlet 35;

[0034] One end of the second water inlet pipe 23 away from the second water inlet 13 in the pipe direction is communicatively provided with a total water outlet pipe 33; one end of the second water outlet pipe 24 away from the water tank 2 in the pipe direction is communicatively provided with a total water inlet pipe 32.

[0035] In a preferred embodiment, the spiral pipe 31, the water inlet 34 and the water outlet 35 are arranged in a matching group, and multiple groups are arranged along the axial direction of the spiral pipe 31;

[0036] Multiple water inlets 34 are fixedly communicated with the total water inlet pipe 32; multiple water outlets 35 are fixedly communicated with the total water outlet pipe 33.

[0037] Please refer to Figure 1 , in this embodiment, the liquid that has absorbed heat through the plate heat exchanger 1 flows into the water tank 2 and is stored. The liquid in the water tank 2 is pumped into the total water inlet pipe 32 when needed, and is divided into multiple spiral pipes 31 through multiple water inlets 34, so that the axial part of the spiral pipe 31 is heated. Then, the liquid in the multiple spiral pipes 31 converges and flows into the total water outlet pipe 3 through multiple water outlets 35, and re-enters the plate heat exchanger 1 through the second water inlet pipe 23 and the second water inlet 13 to absorb heat.

[0038] Multiple spiral pipes 31 are arranged along the axial direction of the spiral pipe 31, jointly forming a cylindrical body. Before the metal wire enters the wire drawing water tank, it first passes through multiple spiral pipes 31 along the axial direction of the cylindrical body. High-temperature liquid flows in the spiral pipes 31, and the metal wire is evenly preheated, which helps the metal wire maintain appropriate plasticity and toughness before wire drawing, thus ensuring the quality and efficiency of wire drawing.

[0039] In a preferred embodiment, water pumps 15 are installed on both the first water inlet pipe 21 and the second water outlet pipe 24.

[0040] Please refer to Figure 1 , in this embodiment, the water pump 15 is used to control the liquid flow in the pipe.

[0041] In a preferred embodiment, valves 116 are installed on the first water inlet 11, the first water outlet 12, the second water inlet 13 and the second water outlet 14.

[0042] Please refer to Figure 1 , in this embodiment, the valve 16 is used to control the opening and closing of the pipe nozzle.

[0043] The working principle of this application:

[0044] The high-temperature liquid in the wire-drawing water tank 1 is pumped into the plate heat exchanger 1 from the first water inlet 11 through the first water inlet pipe 21 by the water pump 15, and then flows back into the wire-drawing water tank from the first water outlet 12 through the first water outlet pipe 22. The high-temperature liquid in the wire-drawing water tank transfers heat through the plate heat exchanger 1. The liquid that absorbs heat through the plate heat exchanger 1 flows into the water tank 2 through the second water outlet 14 and is stored. The liquid in the water tank 2 is pumped into the water inlet main pipe 32 when needed and is divided into multiple spiral pipes 31 through multiple water inlet ports 34, so that the axial part of the spiral pipes 31 is heated. Then, the liquid in the multiple spiral pipes 31 converges and flows into the water outlet main pipe 33 through multiple water outlet ports 35, and then re-enters the plate heat exchanger 1 through the second water inlet pipe 23 from the second water inlet 13 to absorb heat.
