Description

Technical Field

[0001] The present application relates to the field of steel strand manufacturing, and in particular to a surface treatment device for steel strands. Background Art

[0002] Steel strands, made of multiple steel wires, are an important building material widely used in buildings, bridges, roads and other fields. During the manufacturing process, lubricants and other substances are often attached to the surface. At the same time, according to demand, the surface may also be coated with galvanized layers, zinc-aluminum alloy layers, aluminum-clad layers, copper-plated layers or epoxy resins. These attachments and coatings may not only affect the performance and service life of steel strands, but also pose potential threats to the environment and human health.

[0003] Traditional surface treatment methods for steel strands mainly include manual wiping cleaning and chemical immersion cleaning. Although manual wiping cleaning can remove some surface attachments, it is inefficient, consumes a lot of manpower, and the cleaning effect is difficult to guarantee. Although chemical immersion cleaning has a better cleaning effect, it is easy to produce a large amount of wastewater and pollute the environment.

[0004] In recent years, some new types of steel strand surface treatment devices have also emerged, such as the device disclosed in the patent application with announcement number CN217774900U. The device cleans and wipes the steel strands through a brush roller and a rotating wheel assembly, thereby improving the cleaning efficiency. However, the device still has some problems: due to the continuous cleaning method, it is difficult to completely remove the stains on the steel strands after only a single cleaning; at the same time, the degreasing function is combined with the water cleaning function, which easily leads to the rapid accumulation of sewage in the water tank, which is not conducive to the subsequent cleaning of the steel strands and may even cause repeated pollution.

[0005] Therefore, how to provide an efficient surface treatment device for steel strands that can efficiently and thoroughly clean the surface of steel strands while avoiding environmental pollution has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0006] The present application mainly solves the problems of low treatment efficiency and environmental pollution in the traditional steel strand surface treatment method. The present application provides a surface treatment device for steel strand.

[0007] The present application provides a surface treatment device for a steel strand using the following technical solution:

[0008] A surface treatment device for a steel strand, comprising: a wire inlet;

[0009] An electric drive wheel is installed inside the wire inlet, and two groups of electric drive wheels are arranged at upper and lower intervals. The steel strand input end is between adjacent electric drive wheels. A pretreatment box, a cleaning mechanism, and a wire outlet are installed in sequence at the extended end of the wire inlet. Guide wheels are installed at intervals inside the pretreatment box, and a wastewater tank connected to the pretreatment box is installed at the bottom of the pretreatment box. A mounting plate is installed on the right side of the top surface of the pretreatment box, and a pretreatment mechanism is installed on the right side of the mounting plate. The wire outlet is installed on the right side of the cleaning mechanism, and a hot air blower is installed inside the wire outlet.

[0010] By adopting the above technical solution, the steel strands are sprayed with degreasing cleaning agent by using the pretreatment box in conjunction with the pretreatment mechanism. By separating the pretreatment box from the cleaning mechanism, continuous pollution of the water source of the cleaning mechanism is avoided, thereby improving the water resource utilization performance. In addition, the cleanliness of the steel strands is improved by passing through two treatment checkpoints.

[0011] Preferably, support plates are installed at both right end portions of the mounting plate, a rotating shaft is installed inside the support plate, one end of the rotating shaft is connected to the motor, and a first bevel gear is spaced apart on the rotating shaft.

[0012] By adopting the above technical solution, the two groups of first bevel gears are driven to rotate by the motor, thereby synchronously transmitting the two groups of mixing mechanisms in the pretreatment mechanism.

[0013] Preferably, the pretreatment mechanism is composed of a first mixing box, a second mixing box, a water pipe, a liquid infusion pipe, a top cover, a second bevel gear, a mixing blade, a liquid extraction pipe, and a nozzle. The first mixing box and the second mixing box are installed at intervals on the outer side wall of the pretreatment box. The right sides of the first mixing box and the second mixing box are both installed with a water pipe and a liquid infusion pipe, wherein the water pipe is connected to an external water source, and the liquid infusion pipe is connected to an external degreasing cleaning agent tank to continuously supply water and cleaning agent to the first mixing box and the second mixing box. The second bevel gears are horizontally arranged in the first mixing box and the second mixing box, respectively. , and the top of the second mixing box, and is installed and connected with the top covers of the first mixing box and the second mixing box, the second bevel gear is meshed and connected with the first bevel gear, the bottom extending end of the second bevel gear is installed with a mixing blade, the top surface of the top cover is installed with a liquid extraction pipe, the part of the liquid extraction pipe located in the first mixing box and the second mixing box extends to the middle part, the other end of the liquid extraction pipe passes through the side of the mounting plate and the top surface of the pretreatment box and is connected with the nozzle, the nozzle is arranged in a U-shaped structure, the steel strand is located inside the nozzle, and a liquid extraction pump is installed in the connecting end of the liquid extraction pipe and the nozzle.

[0014] By adopting the above technical solution, the second bevel gear drives the mixing blades to fully mix the cleaning agent and water in the first mixing box and the second mixing box, which has a better cleaning effect on the subsequent spraying of the steel strands. The cleaning liquid is driven into the nozzle by the liquid pump, and the cleaning liquid is sprayed on both sides of the steel strands through the nozzle.

[0015] Preferably, the volume of the first mixing box is smaller than that of the second mixing box, the first mixing box is located at one end close to the line inlet, the proportion of cleaning agent in the first mixing box is greater than the proportion of water, the proportion of water in the second mixing box is greater than the proportion of cleaning agent, and the second mixing box is equipped with two sets of liquid extraction pipes and nozzles.

[0016] By adopting the above technical solution, a large amount of cleaning agent is continuously attached to the steel strand at the front end, thereby reducing the processing pressure of the subsequent cleaning link. Since the second mixing box is arranged close to the cleaning mechanism, it is necessary to remove the excess cleaning foam attached to the steel strand while spraying and cleaning the steel strand to avoid excessive foam accumulation in the cleaning mechanism and enhance the flushing intensity.

[0017] Preferably, the cross-section of the wastewater tank is a triangular structure, the bottom of the wastewater tank close to the line inlet is the lowest end, and the bottom close to the cleaning mechanism is the highest end, a drain valve is installed at the lowest end of the bottom of the wastewater tank, and a sewage pipe is installed at the bottom of the drain valve, and the sewage pipe is connected to the external wastewater pipe.

[0018] By adopting the above technical solution, when the nozzle cleans the steel strand, the waste water falls into the waste water tank below, flows into the drain valve along the inclined surface, and is discharged into the waste water pipe through the drain pipe.

[0019] Preferably, the cleaning mechanism consists of a water tank, a connecting port, a limiting wheel, a water inlet pipe, a liquid level sensor, and an operating window. A connecting port is provided on the side of the water tank close to the pretreatment tank, and the other side of the water tank is an outlet. Limiting wheels are installed at intervals inside the water tank, and the setting height of the limiting wheels is lower than the opening height of the connecting port. The water level inside the water tank is located below the connecting port, and the water level exceeds half of the height of the limiting wheel. A liquid level sensor is installed on the wall surface of the water tank below the limiting wheel, and a water inlet pipe is installed on the top surface of the water tank close to the outlet, and the water inlet pipe is connected to an external water supply source, and the water inlet pipe is in a normal flow state. An operating window is provided on the top surface of the water tank.

[0020] By adopting the above technical solution, the steel strand below the limiting wheel is passively contacted with the water in the water tank for washing, and the residual impurities on the steel strand are removed. The cleaned steel strand is discharged from the outlet.

[0021] Preferably, the sewage suction mechanism is composed of a sewage tank, a sewage suction pipe, a connecting hose, a pumping head, and a float. The pumping head is installed in the float. The pumping head is a steel structure. The pumping head is always kept at the water surface of the water tank through the cooperation between the float and the buoyancy of the pumping head. The float is arranged between the connecting port and the limiting wheel. The pumping head is connected to the sewage suction pipe through a connecting hose. The other end of the sewage suction pipe is connected to the sewage tank. A pump body is installed at the connection between the sewage suction pipe and the sewage tank.

[0022] By adopting the above technical solution, the pumping head and the float ring are coordinated to always extract the sewage located on the water surface. Since the float ring is arranged between the connection port and the limiting wheel, it is located at the entrance where the steel strand just enters the water surface, and the density of the residual oil stains and cleaning foam is less than the density of water, so they will float on the water surface. Continuous sewage treatment work can maintain the cleanliness of the water source in the water tank and avoid secondary pollution to the steel strand.

[0023] Preferably, the water outlet point of the water inlet pipe is located between the limiting wheel and the wire outlet, and the water inlet pipe intersects the steel strand vertically.

[0024] By adopting the above technical solution, the water inlet pipe can flush the steel strands again when taking in water, thereby improving the cleanliness and replenishing water in the water tank. When the liquid level sensor detects that the water level drops too quickly, the water inlet amount of the water inlet pipe is controlled to ensure that there is always enough cleaning water in the water tank.

[0025] The present application includes at least one of the following beneficial technical effects:

[0026] 1. The pretreatment box and the pretreatment mechanism are used together to spray the steel strand with degreasing cleaning agent. By separating the pretreatment box and the cleaning mechanism, continuous pollution of the water source of the cleaning mechanism is avoided, the utilization performance of water resources is improved, and the cleanliness of the steel strand is improved through two treatment levels;

[0027] 2. A large amount of cleaning agent is continuously attached to the steel strand at the front end, thereby reducing the processing pressure of the subsequent cleaning link. Since the second mixing box is close to the cleaning mechanism, it is necessary to spray and clean the steel strand while removing the excess cleaning foam attached to the steel strand to avoid excessive foam accumulation in the cleaning mechanism and increase the flushing intensity. The wastewater falls into the wastewater tank below and flows into the drain valve along the inclined surface, and is discharged into the wastewater pipe through the sewage pipe;

[0028] 3. The pumping head cooperates with the float ring to always extract the sewage on the water surface. Since the float ring is set between the connection port and the limiting wheel, it is at the entrance where the steel strand just enters the water surface, and the density of the residual oil stains and cleaning foam is lower than the density of water, so they will float on the water surface. Continuous sewage treatment work can maintain the cleanliness of the water source in the water tank and avoid secondary pollution to the steel strand. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a surface treatment device for a steel strand.

[0037] Reference Figure 1-Figure 2 A surface treatment device for a steel strand comprises: a wire inlet 1, a pretreatment box 2, a wastewater tank 3, a pretreatment mechanism 4, a cleaning mechanism 5, a sewage suction mechanism 6, and a wire outlet 7.

[0038] like Figure 1-Figure 2As shown, an electric drive wheel 101 is installed inside the inlet 1, and two groups of electric drive wheels 101 are arranged at intervals above and below. The input end of the steel strand is between adjacent electric drive wheels 101. The right end of the inlet 1 is sequentially installed with a pretreatment box 2, a cleaning mechanism 5, and an outlet 7. A guide wheel 22 is installed at the inner interval of the pretreatment box 2. A wastewater tank 3 connected to the pretreatment box 2 is installed at the bottom of the pretreatment box 2. A mounting plate 21 is installed on the right side of the top surface of the pretreatment box 2. A pretreatment mechanism 4 is installed on the right side of the mounting plate 21. The pretreatment box 2 and the pretreatment box 2 are connected to the pretreatment box 2. The mechanism 4 is used in conjunction with the steel strand to spray the degreasing cleaning agent on the steel strand. By separating the pretreatment box 2 and the cleaning mechanism 5, continuous pollution of the water source of the cleaning mechanism 5 is avoided, the water resource utilization performance is improved, and the cleanliness of the steel strand is improved through two processing checkpoints. An outlet 7 is installed on the right side of the cleaning mechanism 5, and a hot air blower 71 is installed inside the outlet 7. After the steel strand is degreasingly cleaned by the pretreatment box 2 and the pretreatment mechanism 4, it is washed with water in the cleaning mechanism 5. After cleaning, the water attached to the steel strand is dried and blown away by the hot air blower 71.

[0039] In one embodiment, Figure 3 As shown, support plates 23 are installed at both ends of the right side of the mounting plate 21, and a rotating shaft 24 is installed in the support plate 23. One end of the rotating shaft 24 is connected to the motor 25. The rotating shaft 24 is sleeved with a first bevel gear 26 at intervals. The two groups of first bevel gears 26 are driven by the motor 25 to rotate, thereby synchronously transmitting the two groups of mixing mechanisms in the pretreatment mechanism 4.

[0040] In one embodiment, Figure 3As shown, the pretreatment mechanism 4 is composed of a first mixing box 41, a second mixing box 42, a water pipe 43, a liquid infusion pipe 44, a top cover 45, a second bevel gear 46, a mixing blade 47, a liquid extraction pipe 48, and a nozzle 49. The first mixing box 41 and the second mixing box 42 are installed at intervals on the outer wall of the pretreatment box 2. The right sides of the first mixing box 41 and the second mixing box 42 are both installed with a water pipe 43 and a liquid infusion pipe 44, wherein the water pipe 43 is connected to an external water source, and the liquid infusion pipe 44 is connected to an external degreasing cleaning agent tank, so as to continuously supply water and cleaning agent to the first mixing box 41 and the second mixing box 42. The second bevel gear 46 is horizontally arranged on the top of the first mixing box 41 and the second mixing box 42, and is installed and connected with the top covers 45 of the first mixing box 41 and the second mixing box 42. The second bevel gear 46 is meshed and connected with the first bevel gear 26. A mixing blade 47 is installed at the bottom extension end of the second bevel gear 46, and the rotating shaft 24 and the first bevel gear 26 are driven to rotate by the motor 25, so that the second bevel gear 46 drives the mixing blade 47 to fully mix the cleaning agent and water in the first mixing box 41 and the second mixing box 42, so as to achieve a better cleaning effect for the subsequent spraying of the steel strands. A liquid extraction pipe 48 is installed on the top surface of the top cover 45. The part of the liquid extraction pipe 48 located in the first mixing box 41 and the second mixing box 42 extends to the middle part, and the other end of the liquid extraction pipe 48 passes through the side surface of the mounting plate 21 and the top surface of the pretreatment box 2 and is connected to the nozzle 49. The nozzle 49 is arranged in a U-shaped structure, and the steel strand is located inside the nozzle 49. A liquid extraction pump is installed in the connecting end of the liquid extraction pipe 48 and the nozzle 49, and the cleaning liquid is driven into the nozzle 49 by the liquid extraction pump, and the cleaning liquid is sprayed on both sides of the steel strand through the nozzle 49.

[0041] In one embodiment, Figure 3 As shown, the volume of the first mixing box 41 is smaller than that of the second mixing box 42. The first mixing box 41 is located at one end close to the line inlet 1. The ratio of the cleaning agent in the first mixing box 41 is greater than the ratio of water. A large amount of cleaning agent is continuously attached to the steel strand at the front end, thereby reducing the processing pressure of the subsequent cleaning link. The proportion of water in the second mixing box 42 is greater than the proportion of the cleaning agent. Since the second mixing box 42 is arranged close to the cleaning mechanism 5, it is necessary to remove the excess cleaning foam attached to the steel strand while spraying and cleaning the steel strand to avoid excessive foam accumulation in the cleaning mechanism 5. The second mixing box 42 is equipped with two sets of liquid extraction pipes 48 and nozzles 49 to enhance the flushing intensity.

[0042] In one embodiment, Figure 4As shown, the cross-section of the wastewater tank 3 is a triangular structure, the bottom of the wastewater tank 3 is close to the line inlet 1 as the lowest end, and the bottom close to the cleaning mechanism 5 is the highest end, so that the flushed wastewater can converge along the inclined bottom of the wastewater tank 3, and a drain valve 31 is installed at the lowest end of the bottom of the wastewater tank 3, and a sewage pipe 32 is installed at the bottom of the drain valve 31. The sewage pipe 32 is connected to the external wastewater pipe. When the nozzle 49 cleans the steel strand, the wastewater falls into the wastewater tank 3 below, and converges into the drain valve 31 along the inclined surface, and is discharged into the wastewater pipe through the sewage pipe 32.

[0043] In one embodiment, Figure 5 As shown, the cleaning mechanism 5 is composed of a water tank 51, a connection port 52, a limiting wheel 53, a water inlet pipe 54, a liquid level sensor 55, and an operation window 56. The water tank 51 is provided with a connection port 52 on the side close to the pretreatment tank 2, and the connection port 52 is used to provide a channel for the steel strand. The other side of the water tank 51 is the outlet 7. The limiting wheels 53 are installed at intervals inside the water tank 51. The setting height of the limiting wheels 53 is lower than the opening height of the connection port 52. The water level inside the water tank 51 is located below the connection port 52, and the water level overflows half the height of the limiting wheel 53. The liquid level sensor 55 is installed on the wall of the water tank 51 below the limiting wheel 53. The top of the water tank 51 close to the outlet 7 A water inlet pipe 54 is installed on the surface, and the water inlet pipe 54 is connected to an external water supply source. The water inlet pipe 54 is in a constant flow state. An operation window 56 is opened on the top surface of the water tank 51. The operation window 56 is used to observe the cleaning pollution situation in the water tank 51, and provide an operation guide space for the initial end of the steel strand in the initial stage of cleaning the steel strand. During operation, the steel strand enters the water tank 51 from the connecting port 52, and is restricted by the limiting wheel 53, so that the steel strand forms a V-shaped structure between the connecting port 52, the limiting wheel 53, and the outlet 7, so that the steel strand under the limiting wheel 53 is passively contacted with the water in the water tank 51 for washing, and the residual impurities on the steel strand are removed, and the cleaned steel strand is discharged from the outlet 7.

[0044] In one embodiment, Figure 5As shown, the sewage suction mechanism 6 is composed of a sewage tank 61, a sewage suction pipe 62, a connecting hose 63, a pumping head 64, and a float 65. The pumping head 64 is installed in the float 65. The pumping head 64 is a steel structure. The pumping head 64 is always kept at the water surface of the water tank 51 through the cooperation between the float 65 and the buoyancy of the pumping head 64. The float 65 is arranged between the connecting port 52 and the limiting wheel 53. The pumping head 64 is connected to the sewage suction pipe 62 through the connecting hose 63. The other end of the sewage suction pipe 62 is connected to the sewage tank 61. A pump body is installed at the connection between the sewage suction pipe 62 and the sewage tank 61, and the sewage suction pipe 62, the connecting hose 63, and the pumping head 64 are driven by the pump body to work, so that the pumping head 64 cooperates with the floating ring 65 to always extract the sewage located on the water surface. Since the floating ring 65 is arranged between the connecting port 52 and the limiting wheel 53, it is located at the entrance where the steel strand just enters the water surface, and the density of the residual oil stains and cleaning foam is less than the density of water, so they will float on the water surface. Continuous sewage operation can maintain the cleanliness of the water source in the water tank 51 and avoid secondary pollution to the steel strand.

[0045] In one embodiment, Figure 5 As shown, the water outlet point of the water inlet pipe 54 is located between the limiting wheel 53 and the outlet port 7, and the water inlet pipe 54 intersects the steel strand vertically, so that the water inlet pipe 54 can flush the steel strand again when taking in water, thereby improving the cleanliness and replenishing water in the water tank 51. When the liquid level sensor 55 detects that the water level drops too fast, the water inlet amount of the water inlet pipe 54 is controlled to ensure that there is always enough cleaning water in the water tank 51.

[0046] Working principle: During operation, the steel strand is driven by the electric drive wheel 101 through the wire inlet 1 and enters the pretreatment box 2. The motor 25 drives the rotating shaft 24 and the first bevel gear 26 to rotate, and then the second bevel gear 46 drives the mixing blade 47 to fully mix the cleaning agent and water in the first mixing box 41 and the second mixing box 42. The cleaning liquid is driven into the nozzle 49 through the liquid pump, and the cleaning liquid is sprayed on both sides of the steel strand through the nozzle 49. When the nozzle 49 cleans the steel strand, the waste water falls into the wastewater tank 3 below, and flows into the drain valve 31 along the inclined surface, and is discharged into the wastewater pipeline through the sewage pipe 32. The strand enters the water tank 51 from the connecting port 52, and is restricted in its direction by the limiting wheel 53, so that the steel strand moves in the connecting port 52. The V-shaped structure is formed between the interface 52, the limiting wheel 53, and the outlet 7, so that the steel strand below the limiting wheel 53 is passively contacted with the water in the water tank 51 for washing, and the residual impurities on the steel strand are removed. The cleaned steel strand is discharged from the outlet 7, and the sewage extraction pipe 62, the connecting hose 63, and the pumping head 64 are driven by the pump body to work, so that the pumping head 64 cooperates with the floating ring 65 to always extract the sewage located at the water surface. Since the floating ring 65 is set between the connecting port 52 and the limiting wheel 53, it is at the entrance where the steel strand just enters the water surface, and the residual oil stains and cleaning foam have a density less than the density of water, so they will float on the water surface. Continuous sewage work can maintain the cleanliness of the water source in the water tank 51 and avoid secondary pollution to the steel strand.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
