Description

Technical Field

[0001] This utility model belongs to the field of iron wire processing technology, and specifically relates to a surface spraying device for galvanizing iron wire. Background Technology

[0002] After the outer surface of the iron wire is galvanized, water is needed to rinse off the galvanizing solution adhering to the outer surface of the iron wire. Therefore, after the iron wire is galvanized in the galvanizing bath, it needs to be sent into the water washing bath.

[0003] The zinc plating solution used in the galvanizing process of iron wire is partly acidic, which has strong volatility. This results in some acidic gas remaining around the zinc plating solution. In order to avoid these acidic gases from contaminating the water in the washing tank, and also to facilitate observation of whether the zinc protective layer formed after the iron wire body is galvanized is uniform, a certain gap is placed between the galvanizing tank and the washing tank. The gap is usually more than one meter.

[0004] However, as the wire moves within this interval, the residual galvanizing solution corrodes the coating, resulting in a yellowish hue. This leads to color variations in the galvanized wire, affecting its appearance and making it unsuitable for sale. Therefore, this application proposes a surface spraying device for galvanizing iron wire. Utility Model Content

[0005] The purpose of this invention is to provide a surface spraying device for galvanizing iron wire, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface spraying device for galvanizing iron wire, comprising a galvanizing tank and a washing tank, wherein the galvanizing tank is provided with a galvanizing solution for forming a zinc protective layer on the outer surface of the iron wire body.

[0007] The washing tank is equipped with a spray unit, which is used to remove the zinc plating solution remaining on the outer surface of the iron wire body after galvanizing. A moisturizing tank is provided in the interval between the galvanizing tank and the washing tank.

[0008] The wire body in the moisturizing tank includes a downward sloping part, a horizontal part, and an upward lifting part, and a moisturizing pipe is installed in the moisturizing tank, which includes a downward sloping pipe, a horizontal pipe, and an upward lifting pipe.

[0009] The moisturizing tube is connected to a moisturizing liquid delivery tube, which is connected to a moisturizing liquid storage tank. The moisturizing liquid storage tank is equipped with a power pump for transporting the moisturizing liquid.

[0010] Preferably, the galvanizing bath is provided with at least two immersion hydraulic rollers, which press against the upper side of the wire body, and the immersion hydraulic rollers are provided with guide grooves, into which the wire body is inserted.

[0011] Preferably, the galvanizing bath is provided with several guiding mechanisms, each including two guide wheels and a guide bracket, with the two guide wheels located on the upper and lower sides of the wire body, respectively.

[0012] Preferably, the guide wheel is inserted into the guide bracket, and the guide bracket is connected to the inner wall of the galvanizing tank.

[0013] Preferably, a liquid guiding pipe is provided between the washing pool and the moisturizing pool, and the moisturizing pool is provided with an inlet and an outlet.

[0014] Preferably, the liquid guiding pipe is connected to the outlet, and the liquid guiding pipe is configured as an inclined pipe structure with an opening only at the top.

[0015] Preferably, one end of the liquid guiding pipe abuts against the outer wall of the moisturizing pool, and the other end of the liquid guiding pipe abuts against the outer wall of the washing pool.

[0016] Preferably, the humidification pool is provided with support wheels, and at least two support wheels are provided.

[0017] Preferably, one of the support wheels is located at the junction of the lower inclined portion and the horizontal section, and the other support wheel is located between the horizontal section and the upper section.

[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] Reference Figures 1-3 A surface spraying device for galvanizing iron wire includes a galvanizing tank 1 and a washing tank 2. The galvanizing tank 1 is provided with a galvanizing solution for forming a zinc protective layer on the outer surface of the iron wire body 7. After galvanizing, the iron wire body 7 can improve its aesthetic performance and also protect the iron wire body 7 to prevent it from rusting.

[0027] After the iron wire body 7 enters the zinc plating solution, it acts as the cathode, and zinc ions will form a uniform zinc protective layer on the outer surface of the iron wire body 7.

[0028] Specifically, in order to make the protective layer formed on the outer surface of the wire body 7 uniform, at least two immersion hydraulic rollers 101 are provided in the galvanizing bath 1. The immersion hydraulic rollers 101 press on the upper side of the wire body 7, and the immersion hydraulic rollers 101 are provided with guide grooves. The wire body 7 is inserted into the guide grooves. The guide grooves are to prevent the wire body 7 from detaching from the immersion hydraulic rollers 101.

[0029] More specifically, the galvanizing tank 1 is equipped with several guiding mechanisms. The guiding mechanisms are used to guide the wire body 7 so that the wire body 7 moves stably along the designed direction. The guiding mechanism includes two guide wheels 102 and a guide bracket 103. The two guide wheels 102 are located on the upper and lower sides of the wire body 7 respectively. The guide wheels 102 are inserted into the guide bracket 103. The guide bracket 103 is connected to the inner wall of the galvanizing tank 1.

[0030] The washing tank 2 is equipped with a spray unit to remove residual zinc plating solution from the outer surface of the iron wire body 7 after galvanizing. The zinc plating solution can be either an acidic or alkaline solution. If the zinc plating solution is acidic, some acidic gas will evaporate around the zinc plating solution. In order to avoid these acidic gases or zinc plating solution splashing directly into the washing tank 2, and also to facilitate observation of whether the zinc protective layer formed after galvanizing the iron wire body 7 is uniform, there is a certain gap between the galvanizing tank 1 and the washing tank 2. The gap is usually more than one meter. Within this gap, during the movement of the iron wire body 7, the residual zinc plating solution on it will corrode the coating. The corroded coating will be yellow, which will result in color difference after galvanizing the iron wire body 7, affecting the appearance of the iron wire body 7 and making it inconvenient for subsequent sales. Therefore, a moisturizing tank 3 is set in the gap between the galvanizing tank 1 and the washing tank 2.

[0031] Specifically, the wire body 7 in the moisturizing pool 3 includes a downward sloping part 301, a horizontal line part 302, and an upward lifting part 303, and a moisturizing tube 4 is provided in the moisturizing pool 3. The moisturizing tube 4 includes a downward sloping tube 401, a horizontal tube 402, and an upward lifting tube 403. The downward sloping tube 401, the horizontal tube 402, and the upward lifting tube 403 correspond one-to-one with the downward sloping part 301, the horizontal line part 302, and the upward lifting tube 303.

[0032] More specifically, there are at least two support wheels. One support wheel is located at the junction of the lower inclined part 301 and the horizontal part 302, and the other support wheel is located between the horizontal part 302 and the upper part 303. The support wheels are connected to a support frame, and the support frame is connected to the inner wall of the humidification pool 3.

[0033] After the wire body 7 enters the moisturizing tank 3, it forms a downward sloping part 301, a horizontal part 302, and an upward lifting part 303 under the action of the support wheel. The moisturizing pipe 4 includes a downward sloping pipe 401, a horizontal pipe 402, and an upward lifting pipe 403. The moisturizing liquid sprayed from the moisturizing pipe 4 is aimed at the wire body 7, which can keep the wire body 7 moist and prevent the zinc plating liquid adhering to the wire body 7 from corroding the protective layer. The height of the wire body 7 in the area aimed at by the moisturizing pipe 4 is lower than that in the zinc plating tank 1 (height here refers to the height of the section from the right side of the zinc plating tank 1 into the moisturizing tank 3) and the water washing tank 2. In this way, the liquid sprayed from the moisturizing pipe 4 can be prevented from flowing into the zinc plating tank 1 and the water washing tank 2, which facilitates the subsequent classification and treatment of the liquid.

[0034] More specifically, the moisturizing tube 4 is connected to a moisturizing liquid delivery tube 5, which in turn is connected to a moisturizing liquid storage tank 6. The moisturizing liquid storage tank 6 contains a power pump for transporting the moisturizing liquid. The power pump delivers the moisturizing liquid through the moisturizing liquid delivery tube 5 into the moisturizing tube 4, keeping the wire body 7 below the moisturizing tube 4 moist by dripping, thus preventing the zinc plating solution adhering to the wire body 7 from corroding the protective layer.

[0035] Furthermore, to prevent the liquid from falling directly onto the ground, a liquid guiding pipe 8 is installed between the washing pool 2 and the moisturizing pool 3. The moisturizing pool 3 is equipped with an inlet 304 and an outlet 305. The liquid guiding pipe 8 is connected to the outlet 305, and the liquid guiding pipe 8 is designed as an inclined pipe structure with only the top opening. The two ends of the liquid guiding pipe 8 are respectively abutted against the outer wall of the moisturizing pool 3 and the outer wall of the washing pool 2.

[0036] The liquid guiding pipe 8 can prevent the liquid on the wire body 7 from falling directly to the ground through the gap between the washing pool 2 and the moisturizing pool 3, keeping the ground dry and reducing the amount of subsequent cleaning work.

[0037] Working principle:

[0038] After the wire body 7 enters the moisturizing pool 3, it forms a downward inclined part 301, a horizontal part 302, and an upward part 303 under the action of the support wheel. The moisturizing tube 4 includes a downward inclined tube 401, a horizontal tube 402, and an upward tube 403.

[0039] The power pump delivers the moisturizing liquid into the moisturizing pipe 4 through the moisturizing liquid delivery pipe 5, and drips it onto the iron wire body 7, which keeps the iron wire body 7 moist and prevents the zinc plating liquid adhering to the iron wire body 7 from corroding the protective layer.

[0040] The height of the wire body 7 at the area aligned with the moisturizing tube 4 is lower than that of the wire body 7 inside the galvanizing tank 1 and the washing tank 2. This prevents the liquid sprayed from the moisturizing tube 4 from flowing into the galvanizing tank 1 and the washing tank 2, facilitating subsequent liquid classification and treatment.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
