Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a cooling water tank for metal surface treatment. Background Technology

[0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to a certain appropriate temperature and held for a period of time, and then immersed in a quenching medium for rapid cooling. After quenching, the metal can obtain a surface layer with high hardness and favorable internal stress distribution, thereby improving the wear resistance and fatigue resistance of the workpiece. After quenching, the metal is often placed in a cooling water bath for rapid cooling.

[0003] Currently, when medium and low carbon steel is quenched in a cooling water tank, the air bubbles on the surface of the steel are difficult to disperse when they come into contact with water, which affects the quenching effect of this type of metal. Furthermore, when medium and low carbon steel enters a water tank with a higher water level, the edge of the tank is prone to overflowing due to the air bubbles during metal quenching, resulting in water overflowing from the tank opening and being lost. To address this, we propose a cooling water tank for metal surface treatment. Summary of the Invention

[0004] The main objective of this invention is to provide a cooling water tank for metal surface treatment. An improved design involves incorporating a jetting mechanism within the tank. This mechanism, assembled inside the tank, creates a high-pressure water jet. When low-carbon steel is immersed in the tank for quenching, the high-pressure water jet disperses air bubbles on the steel's surface, aiding in effective cooling. Furthermore, water overflowing from the tank is collected by the outer hopper of the jetting mechanism, ensuring optimal immersion cooling of the steel after surface treatment. This effectively addresses the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cooling water tank for metal surface treatment includes a tank and a spraying mechanism. The spraying mechanism includes a support plate, a water pump, a bent pipe, a filter cartridge, a connecting pipe, a straight pipe, a bottom pipe with a fold, an injection pipe, an outer hopper, and a U-shaped baffle frame. A support plate for mounting the water pump is welded to the wide inner wall of the tank. The water pump's inlet and outlet pipes are flanged with the bent pipe and connecting pipe, respectively. A threaded ring for screwing on the filter cartridge is welded to the bottom opening of the bent pipe. Furthermore, the single-port cylinder surface of the filter cartridge is provided with surface filter holes. The bottom pipe port of the bent connecting pipe away from the water pump is connected to a folded bottom pipe by a straight connecting pipe, and the folded bottom pipe is submerged in the water tank. An ejector pipe is installed on the upper pipe wall of the folded bottom pipe, and the outer pipe port of the ejector pipe faces the opening of the water tank. A through hole is provided on the outer wall of the water tank, and an outer hopper is welded upward to the outside of the water tank below the through hole. A U-shaped baffle is welded at the upper seat opening of the outer hopper.

[0007] Furthermore, flanges are welded to the ends of the bent pipe and the connecting pipe, and the bent pipe and the connecting pipe are locked to the inlet and outlet flanges of the water pump respectively with their own flanges, bolts and nuts; the flanges welded to the ends of the bent pipe and the connecting pipe can be flanged to the inlet and outlet flanges of the water pump.

[0008] Furthermore, the tube body of the folded-back bottom tube is a single-port tube body, and the single port of the folded-back bottom tube is heat-fused to the port of the straight connecting tube; after the single port of the folded-back bottom tube is connected to the straight connecting tube, pressurized water can be injected, and the pressurized water can be smoothly injected into the ejection pipe and sprayed outwards within the folded-back bottom tube.

[0009] Furthermore, the injection tube is heat-fused together with the tube body of the fold-back bottom tube after being inserted into it, and the injection tube is arranged along the length of the tube body on the cylindrical tube surface of the fold-back bottom tube; after the injection tube and the fold-back bottom tube are heat-fused together, they can maintain good connectivity and interoperability, ensuring that pressurized water in the fold-back bottom tube can be discharged from the injection tube.

[0010] Furthermore, the base of the water pump is locked with a fastening bolt between it and the support plate, and a gap is reserved between the support plate and the water tank for the passage of a direct connection pipe; after the base of the water pump is bolted to the surface of the support plate, the direct connection pipe can enter the water tank from between the support plate and the water tank.

[0011] Furthermore, the bottom plate of the outer bucket seat is welded to the water tank to form a seat cavity for containing water; water overflowing from the top of the water tank can enter the seat cavity at the outer bucket box for collection.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention improves upon traditional steel by incorporating a jetting mechanism within the water tank. This mechanism, assembled inside the water tank, creates a high-pressure water jet structure. When low-carbon steel is suspended into the water tank for quenching, the high-pressure water jet disperses air bubbles on the surface of the steel, aiding in effective cooling. Furthermore, water overflowing from the water tank is collected by the outer hopper of the jetting mechanism, ensuring proper immersion cooling of the steel after surface treatment and preventing water loss due to overflow.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-2 As shown, a cooling water tank for metal surface treatment includes a tank 1 and a surrounding spray mechanism 2. The surrounding spray mechanism 2 includes a support plate 3, a water pump 4, a bent pipe 5, a filter cylinder 7, a connecting pipe 9, a straight pipe 10, a bottom pipe 11, an injection pipe 12, an outer hopper 14, and a U-shaped baffle frame 15. The support plate 3 for mounting the water pump 4 is welded to the inner wall of the wide side of the tank 1. The inlet and outlet pipes of the water pump 4 are respectively flanged with the bent pipe 5 and the connecting pipe 9. A threaded ring 6 for screwing on the filter cylinder 7 is welded to the bottom of the bent pipe 5. The filter cylinder 7 has a surface filter hole 8 on its single-port cylinder surface. The bent connecting pipe 9 is connected to the bottom pipe opening away from the water pump 4 by a straight connecting pipe 10 and a folded bottom pipe 11. The folded bottom pipe 11 is submerged in the water tank 1. An ejector pipe 12 is installed on the upper pipe wall of the folded bottom pipe 11. The outer pipe opening of the ejector pipe 12 faces the opening of the water tank 1. The water tank 1 has a through hole 13 on its outer wall. An outer hopper 14 is welded upward to the outside of the water tank 1 below the through hole 13. A U-shaped baffle 15 is welded to the upper seat opening of the outer hopper 14.

[0019] Flanges are welded to the ends of the bent pipe 5 and the bent connecting pipe 9, and the bent pipe 5 and the bent connecting pipe 9 are locked to the inlet and outlet pipe flanges of the water pump 4 by their own flanges in conjunction with bolts and nuts; the flanges welded to the ends of the bent pipe 5 and the bent connecting pipe 9 can be flanged to the inlet and outlet pipe flanges of the water pump 4.

[0020] The folded bottom pipe 11 has a single-port pipe body, and the single port of the folded bottom pipe 11 is heat-fused to the port of the straight connecting pipe 10. After the single port of the folded bottom pipe 11 is connected to the straight connecting pipe 10, pressurized water can be injected, and the pressurized water can be smoothly injected into the ejection pipe 12 and sprayed outwards within the folded bottom pipe 11.

[0021] The ejector tube 12 is heat-fused together with the tube body of the fold-back bottom tube 11 after being inserted into the tube body, and the ejector tube 12 is arranged along the length of the tube body on the cylindrical tube surface of the fold-back bottom tube 11; after the ejector tube 12 and the fold-back bottom tube 11 are heat-fused together, they can maintain good connectivity and interoperability, ensuring that pressurized water in the fold-back bottom tube 11 can be discharged from the ejector tube 12.

[0022] The base of the water pump 4 is locked with a fastening bolt to the support plate 3, and a gap is reserved between the support plate 3 and the water tank 1 for the straight connecting pipe 10 to pass through. After the base of the water pump 4 is locked to the surface of the support plate 3 with bolts, the straight connecting pipe 10 can enter the water tank 1 from between the support plate 3 and the water tank 1.

[0023] The bottom plate of the outer bucket 14 is welded to the water tank 1 to form a seat cavity for holding water; water overflowing from the top of the water tank 1 can enter the seat cavity of the outer bucket 14 for collection.

[0024] It should be noted that this utility model is a cooling water tank for metal surface treatment. After the improvement of the enclosure mechanism 2 at the tank body of the water tank 1, the water pump 4 installed at the support plate 3 can be electrically connected to an external power source for control. Then, the folded bottom pipe 11, which is connected to the water pump 4 outlet pipe by the bend pipe 9 and the straight pipe 10, can be placed into the water tank 1. A heavy object can be used to press part of the folded bottom pipe 11 into the water tank 1, or other clamps can be used to fix the folded bottom pipe 11 to the water tank 1. Then, the bend pipe 4 connected to the water pump 4 inlet pipe is screwed with the filter cylinder 7 by the threaded ring 6 and then extends into the water tank 1. At this time, the water tank 1 can be filled with metal surface treatment water normally. When the low carbon steel is hoisted into the water tank 1 for quenching, the water pump... 4 can be turned on, and then the water pump 4 draws water from the filter cylinder 7 with the surface filter hole 8 and enters the return bottom pipe 11 along the bent suction pipe 5, its own pump chamber, the bent connecting pipe 9 and the straight connecting pipe 10. The pressurized water in the return bottom pipe 11 is ejected from the injection pipe 12 to the medium and low carbon steel with a high pressure water flow. The high pressure water flow disperses the air bubbles on the surface of the medium and low carbon steel when it comes into contact with water, which helps the medium and low carbon steel to be cooled and cooled down better in the water tank 1. The water overflowing from the water tank 1 due to the air bubbles can flow into the outer hopper 14. The outer hopper 14 is surrounded by a U-shaped baffle 15 to raise the water splash barrier. The water in the outer hopper 14 can be kept in communication with the water tank 1 through the through hole 13, so that the medium and low carbon steel can be cooled down better after surface treatment in the water tank 1.
