Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment. More specifically, this utility model relates to a wire drawing circulating cooling water tank, which is particularly suitable for solving the problem of mold blockage caused by the deposition of impurities in the cooling water. Background Technology

[0002] In the metal wire drawing process, cooling water, as a key process medium, is required to forcibly cool the high-speed drawn wire as it flows through the wire drawing die. During the wire drawing process, the drawing powder used as lubricant for the metal wire inevitably enters the cooling water die, forming the following complex contaminants: suspended impurities and a foam layer, mainly composed of stable foam formed by the mixture of drawing powder and its grease with microbubbles; and scale deposits, mainly calcium and magnesium ions precipitating and forming scale at high temperatures.

[0003] Traditional cooling water treatment methods have significant drawbacks. Direct discharge systems discharge unpurified water directly, which contradicts the principles of environmental protection and water conservation. Single-stage sedimentation tanks rely solely on gravity settling, resulting in insufficient removal of many particles. These particles circulate with the water flow, clogging the cooling water channels of the die, leading to decreased heat exchange efficiency and localized overheating and oxidation on the wire surface. Therefore, there is an urgent need to develop a low-energy-consumption wire drawing circulating cooling water tank that can separate micron-level impurities, enabling the recycling of cooling water. Utility Model Content

[0004] The purpose of this invention is to provide a wire drawing circulating cooling water tank that solves the problem of mold blockage caused by wire drawing powder and scale in the cooling water through a stepped physical purification structure and closed-loop water circulation design; at the same time, it achieves zero chemical additives and low energy consumption operation, thereby improving the wire drawing cooling efficiency from the root.

[0005] The technical solution adopted by this utility model to solve this technical problem is: a wire drawing circulating cooling water tank, comprising four water tanks connected in sequence: a water storage tank, a primary sedimentation tank, a secondary sedimentation tank, and a tertiary filtration tank;

[0006] The side wall of the water storage tank is equipped with an overflow outlet that connects to the primary sedimentation tank. The primary sedimentation tank and the secondary sedimentation tank are separated by an overflow baffle. The outlet of the secondary sedimentation tank is connected to the tertiary filtration tank through a pipe.

[0007] The first-stage sedimentation tank has a 10-20° sloping bottom and a sewage outlet is located on the lower side of the slope. The second-stage sedimentation tank is equipped with an inclined plate assembly with an angle of 55-65° to the horizontal plane. The third-stage filtration tank has a multi-layer filter screen frame and is connected to the inlet of the wire drawing machine mold box via a water supply pipe equipped with a clean water pump. The drain pipe of the mold box is connected to the water storage tank.

[0008] As a further embodiment of this utility model, the inclined plate group includes three sets of inclined plates, which are arranged at intervals along the horizontal direction with a plate spacing of 40-60mm. The inclined plates on both sides are connected to the top of the secondary sedimentation tank, and the inclined plate in the middle is connected to the bottom of the secondary sedimentation tank.

[0009] As a further embodiment of this utility model, the multi-layer filter frame comprises a double-layer structure of an 80-100 mesh primary filter and a 120-150 mesh fine filter.

[0010] As a further embodiment of this utility model, the sewage outlet of the primary sedimentation tank is provided with a sewage guide trough, the sewage guide trough having a longitudinal downward inclination angle of 3-5°, and the sewage guide trough being connected to the sewage valve flange.

[0011] As a further embodiment of this utility model, an oil skimmer is provided on the liquid surface of the water storage tank.

[0012] As a further aspect of this utility model, a liquid level sensor is installed in the three-stage filtration tank, and the signal output terminal of the liquid level sensor is connected to a control terminal, which controls the start and stop of the clean water pump.

[0013] As a further embodiment of this utility model, a water quality monitoring instrument is provided on the water supply pipe.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. The wire drawing circulating cooling water pool of this application effectively removes wire drawing powder impurities and foam from the cooling water through a three-stage synergistic purification mechanism of gravity sedimentation, inclined plate interception, and gradient filtration.

[0016] 2. The cooling water circulation after impurity removal in the wire drawing circulating cooling water tank of this application effectively reduces the cleaning cycle of the mold box, reduces the downtime of a single machine, and increases production capacity. In addition, the closed-loop cooling water circulation reduces the amount of cooling water replenished.

[0020] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0021] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific implementation process is as follows:

[0023] like Figure 1 As shown, this utility model provides a wire drawing circulating cooling water tank, which includes four water tanks connected in sequence: a water storage tank 1, a primary sedimentation tank 2, a secondary sedimentation tank 3, and a tertiary filtration tank 4.

[0024] The side wall of the water storage tank 1 is provided with an overflow outlet, which is connected to the primary sedimentation tank 2 through a pipe. The primary sedimentation tank 2 and the secondary sedimentation tank 3 are an integrated tank body. The primary sedimentation tank 2 and the secondary sedimentation tank 3 are separated by an overflow baffle. The outlet of the secondary sedimentation tank is connected to the tertiary filtration tank 4 through a pipe.

[0025] The primary sedimentation tank 2 has a 10-20° inclined slope 5 at its bottom, and a sewage outlet is provided on the lower side of the slope of the primary sedimentation tank 2, preferably on the side that is far away from the secondary sedimentation tank 3. The secondary sedimentation tank 3 is equipped with an inclined plate group with an angle of 55-65° to the horizontal plane. The angle between the secondary sedimentation tank 3 and the horizontal plane is set so that the particles can slide down the inclined plate 6 quickly and maximize the effective sedimentation area of ​​the inclined plate 6. For particles of 20-100μm, this angle can balance the particle sedimentation speed with the water flow upward speed, ensuring that the particles complete sedimentation when passing through the inclined plate 6. The tertiary filter tank 4 has a built-in detachable multi-layer filter screen frame. The tertiary filter tank 4 is connected to the inlet of the wire drawing machine mold box through a water supply pipe 10 equipped with a clean water pump, and the mold box drain pipe is connected to the water storage tank 1.

[0026] In the above technical solution, the cooling water circulation process of the wire drawing circulating cooling water tank mainly includes: opening the overflow valve of the water storage tank 1, and the water flows into the primary sedimentation tank 2 by gravity through the pipeline. Large particles (≥100μm) are initially settled using the 10-20° inclined surface. Then, the cooling water flows into the secondary sedimentation tank 3 through the overflow baffle. When the water flows through the inclined plate group, 20-100μm particles settle on the surface of the inclined plate 6. The clean water flows into the tertiary filtration tank 4 through the outlet of the secondary sedimentation tank 3. In the tertiary filtration tank 4, the water flows through the primary filter screen 7 and the fine filter screen 8 for double filtration to remove particles ≤20μm. The clean water pump is started to deliver the clean water to the wire drawing machine die box through the water supply pipe 10.

[0027] This technical solution may also include the following technical details to better achieve the technical effect: The inclined plate group includes three sets of inclined plates 6, which are arranged at intervals along the horizontal direction with a plate spacing of 40-60mm. The inclined plates 6 on both sides are connected to the top of the secondary sedimentation tank 3, and the inclined plate 6 in the middle is connected to the bottom of the secondary sedimentation tank 3, so that the water flows through the secondary sedimentation tank 3 in a serpentine manner. The inclined plate group is preferably made of corrosion-resistant plastic. The inclined plates 6 can be connected to the top or bottom of the secondary sedimentation tank 3 by plugging, which is convenient for disassembly, cleaning, maintenance and replacement. Preferably, the plate spacing is 50mm.

[0028] This technical solution may further include the following technical details to better achieve the technical effect: the multi-layer filter frame comprises a double-layer structure of an 80-100 mesh stainless steel primary filter 7 and a 120-150 mesh nylon fine filter 8, with the primary filter 7 positioned above the fine filter 8. More preferably, the fine filter 8 can be independently replaced. In a more preferred embodiment, the multi-layer filter frame is positioned above the body of the three-stage filtration tank 4, and the outlet of the three-stage filtration tank 4 is located in the middle or lower-middle part of the tank wall, thereby avoiding the upper foam layer and sedimentation zone and ensuring water quality stability.

[0029] This technical solution may also include the following technical details to better achieve the technical effect: the sewage outlet of the primary sedimentation tank 2 is provided with a sewage guide trough 9, the sewage guide trough has a longitudinal downward inclination angle of 3-5°, and the sewage guide trough is connected to the sewage valve flange.

[0030] This technical solution may also include the following technical details to better achieve the technical effect: the liquid surface of the water storage tank 1 is equipped with an oil skimmer, and in a more preferred embodiment, the width of the oil skimmer's suction band covers more than 80% of the width of the tank body.

[0031] This technical solution may also include the following technical details to better achieve the technical effect: A liquid level sensor is installed inside the three-stage filtration tank 4. The signal output terminal of the liquid level sensor is connected to a control terminal, which controls the start and stop of the clean water pump. In actual use, a minimum water level H1 is set. The liquid level sensor detects the water level in the three-stage filtration tank 4. When the water level is lower than the set minimum water level, the control terminal controls the clean water pump to stop. An opening water level H2 can also be set. When the water level is higher than the set opening water level, the control terminal controls the clean water pump to start. The liquid level sensor is installed below the multi-layer filter screen frame and above the center line of the outlet hole of the three-stage filtration tank 4.

[0032] This technical solution may also include the following technical details to better achieve the technical effect: a water quality monitor is installed on the water supply pipe 10, which detects the concentration of suspended solids in the water in real time and transmits the data to the control terminal.

[0033] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
