Description

Technical Field

[0001] This utility model relates to the field of cooling pool technology, and more specifically to a cooling pool for rapid cooling of galvanized parts. Background Technology

[0002] The cooling bath for galvanized parts is an important component of the hot-dip galvanizing process. During hot-dip galvanizing, steel products undergo pickling, cleaning, fluxing, and drying before entering the zinc bath for galvanizing. They then need to be rapidly cooled to fix the zinc layer and reduce zinc oxidation.

[0003] Chinese patent application number 201921706501.6 discloses a galvanizing liquid circulation cooling device. The device includes a cooling tank with an opening at the bottom left side. An impurity collection hopper is sealed to the opening, and a control valve is installed at the outlet end of the hopper. Double rows of S-shaped heat exchange tubes are arranged in the cooling tank to the right of a partition, with the coolant flowing from the lower part of the tubes to the upper part. A drain pipe is located on the lower part of the right outer wall of the cooling tank. While this patent effectively cools the liquid in the cooling tank, the following problems exist in its use:

[0004] 1. The internal liquid is in a static state, and the cooling device can only effectively cool the surrounding liquid, with limited overall cooling effect. This results in uneven internal water temperature and increases the cooling time for parts.

[0005] 2. Zinc dross and oxides on the surface of the molten zinc bath will adhere to the surface of the parts. When the parts are cooled, they will enter the cooling pool along with the workpieces. During the cooling process, they will peel off and fall into the cooling pool, affecting the normal use of the cooling pool and reducing the cooling efficiency.

[0006] Therefore, it is necessary to propose a cooling pool for rapid cooling of galvanized parts to solve the above problems. Utility Model Content

[0007] To address the above problems, this utility model provides a cooling pool for rapid cooling of galvanized parts. It improves the fluidity of the coolant, thereby rapidly cooling the galvanized parts and preventing uneven cooling of the coolant. At the same time, it can capture and collect impurities so that they can be discharged when the acid solution is replaced.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 A cooling tank for rapid cooling of galvanized parts includes a tank body (101) filled with coolant. A bottom plate (102) is connected to the bottom of the tank body (101), and side plates (103) are connected to both sides of the tank body (101). The coolant flows between the inner and outer sides of the side plates (103). The bottom of the side plates (103) is connected to the bottom plate (102). Centrifugal fan blades (104) are rotatably connected between the bottom plate (102) and the bottom of the tank body (101). When the centrifugal fan blades (104) rotate, they draw water from the area between the two side plates (103) and throw it towards the edge area inside the tank body (101). At this time, the coolant flows between the side plates (103) and the tank body (101). The liquid level between the two side plates 103 will rise. When the liquid level exceeds a certain height, it will pass over the side plate 103 and enter the middle area. The bottom plate (102) is provided with through holes corresponding to the inlet of the centrifugal fan blade (104). The liquid in the area between the two side plates 103 will enter the centrifugal fan blade 104 through the through holes on the bottom plate 102. Cooling pipes (105) are connected to both sides of the pool body (101). The two ends of the cooling pipes (105) are connected to external cold water circulation devices. The external cooling devices are used to cool the coolant in the pool body 101. A first baffle plate (106) is connected between the two side plates (103). When the internal coolant flows, the first baffle plate 106 is used to intercept impurities.

[0027] In use, the liquid in the area between the two side plates 103 is drawn in by the centrifugal fan blades 104 and pushed to a position close to the edge of the pool body 101. During the flow, it comes into contact with the cooling pipes 105, which cools the liquid. When the liquid between the side plates 103 and the pool body 101 exceeds the side plates 103, it will flow back to the area between the two side plates 103. This cycle improves the circulation capacity of the liquid and enhances the cooling effect on the liquid.

[0028] During use, it is necessary to clean the debris trapped on the first baffle plate 106 to avoid excessive accumulation of impurities that could affect the flow of the liquid. The following provides a structure for scraping impurities off the first baffle plate 106: A slag storage chamber (107) is provided at one end of the pool body (101). A first one-way plate (201) is rotatably connected between the slag storage chamber (107) and the pool body (101). The first one-way plate 201 is rotatably connected to the opening connecting the pool body 101 and the slag storage chamber 107, used to... The connection between the two is blocked, and the first one-way plate 201 can only rotate towards the inside of the slag storage chamber 107. A torsion spring connects the first one-way plate 201 and the side wall of the slag storage chamber 107, allowing the first one-way plate 201 to cover the connection between the pool body 101 and the slag storage chamber 107, blocking the communication between the pool body 101 and the slag storage chamber 107. That is, the first one-way plate 201 is in a vertical state, and it is only when it comes into contact with the protrusion 204 on the scraper 203 that it is pushed aside by the scraper 203, at which point it is cleaned. The collected impurities can enter the slag storage chamber 107. The top of the pool body 101 and the slag storage chamber 107 are interconnected and have through holes for maintaining the balance of coolant on both sides. The slag storage chamber (107) is connected to a second baffle plate (202) located on top of the first one-way plate (201). When there is coolant in the slag storage chamber 107, the impurities collected in the slag storage chamber 107 will move upward and flow back into the pool body 101. The second baffle plate 202 can intercept the captured impurities. The scraper (203) is confined to the bottom of the slag storage chamber 107 and will not move upward. The pool body (101) is equipped with an axially movable scraper (203). The bottom of the scraper (203) contacts the first baffle plate (106). The scraper (203) moves back and forth on the first baffle plate 106 to push the impurities intercepted on the first baffle plate 106 into the slag storage chamber 107. Both ends of the scraper (203) are connected to protrusions (204) corresponding to the first one-way plate (201). (See reference...) Figure 4 , Figure 4 The image shows a cross-sectional view of the scraper 203 and the second one-way plate 208. The protrusion 204 can guide the impurities on both sides toward the middle position during scraping. At the same time, it can contact the first one-way plate 201 before the impurities, thereby pushing the first one-way plate 201 inward. At this time, the scraped impurities can enter the slag storage chamber 107.

[0029] The scraper 203 needs to move back and forth within the pool body 101. The following provides a structure for driving the scraper 203 to move back and forth: Specifically, refer to... Figure 3The pool body (101) is rotatably connected to a reciprocating screw (205) that is threadedly connected to the scraper (203). All connections are sealed and waterproof. One end of the pool body (101) is connected to a first motor (206). The output end of the first motor (206) is connected to the reciprocating screw (205). The first motor 206 drives the scraper 203 to perform a back-and-forth scraping action on the first slag baffle 106.

[0030] The following provides a structure for stabilizing the back-and-forth movement of the scraper 203: Specifically, refer to... Figure 3 The top two sides of the first slag baffle (106) are connected to guide bosses (207). The scraper (203) is slidably connected to the guide bosses (207). The guide bosses 207 are used to stabilize the back-and-forth movement of the scraper 203. The bottom of the scraper (203) is rotatably connected to a second one-way plate (208). When the scraper 203 moves toward the slag storage chamber 107, the second one-way plate 208 will be in a vertical state. At this time, it can scrape off the impurities on the first slag baffle 106. When the scraper 203 moves toward the end away from the slag storage chamber 107, the second one-way plate 208 will become tilted. At this time, it loses the pushing effect on the impurities on the first slag baffle 106. Therefore, it has the function of pushing impurities in one direction.

[0031] When the liquid flows between the pool body 101 and the side plate 103, it will splash because it is thrown by the centrifugal fan blades 104. The following is a structure to prevent splashing: Specifically, refer to Figure 3 The top of the pool body (101) is connected to a protective plate (108), which can prevent impurities from entering the area between the side plate 103 and the wall of the pool body 101. The bottom of the protective plate (108) is connected to a water-passing plate (109), which is connected to the top of the side plate (103). The water-passing plate 109 supports the side plate 103 and the protective plate 108, and at the same time prevents foreign objects from entering. The water-passing plate (109) has through holes for liquid to pass through.

[0032] In use, multiple centrifugal fan blades 104 need to rotate synchronously to improve the liquid conveying capacity. The following provides a structure for driving the rotation of multiple centrifugal fan blades 104: Specifically, refer to... Figures 1 to 3A second motor (111) is connected to one side of the pool body (101). The second motor (111) and the first motor (206) are preferably servo motors, used to drive multiple centrifugal fan blades 104 to rotate. The output end of the second motor (111) and the rotating shaft of the centrifugal fan blades (104) are connected by a chain drive structure (112). The chain drive structure 112 consists of a chain and a sprocket. The chain drives multiple sprockets to rotate, thereby driving multiple centrifugal fan blades 104 to rotate synchronously. One sprocket is installed at the output end of the second motor (111).

[0033] When the cleaning fluid in tank 101 needs to be replaced, the collected impurities also need to be cleaned, resulting in a huge workload. The following is a structure that can clean up impurities along with the waste cleaning fluid: Specifically, refer to... Figure 3 The bottom of the slag storage chamber (107) is connected to a drain pipe (110), which is located at the lowest position of the slag storage chamber 107. When the waste liquid in the slag storage chamber 107 is discharged, the flowing waste liquid will carry the impurities in the slag storage chamber 107 out together. One end of the pool body (101) is connected to a water supply pipe (113). When the liquid in the pool body 101 decreases, new coolant can be supplied to the pool body 101 through the water supply pipe 113.

[0034] In this embodiment, the pool 101 stores coolant. Parts requiring cooling are placed into the pool 101 using a hoist, thereby cooling the parts. Centrifugal fan blades 104 push the water in the middle area towards the edge of the pool 101. The water at the edge flows back to the middle area through the through holes on the water-passing plate 109, thus circulating the water. During the flow, it comes into contact with the cooling pipes 105 on both sides. Through the circulation of the liquid, the coolant is rapidly cooled, preventing uneven temperature distribution and improving the cooling efficiency for the galvanized parts. The first motor 206 drives the scraper 203 to move back and forth on the first slag baffle 106 via the reciprocating screw 205. This pushes impurities through the first one-way plate 201 into the slag storage chamber 107, collecting the impurities and preventing their accumulation, which could affect normal use.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
