Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to an AQ liquid level detection and alarm device. Background Art

[0002] The AQ liquid in the steel cord electroplating water bath, also known as the electroplating liquid, is a special liquid used in the electroplating process. This liquid contains metal ions to be plated on the surface of the steel cord, as well as some additives such as buffers, complexing agents, conductive salts, etc., which are used to control the chemical reaction of the electroplating process and the quality of the coating.

[0003] During the electroplating process, the steel cord is immersed in the AQ solution as the cathode, and a direct current is applied between the steel cord and the anode. Under the action of the current, the metal ions in the AQ solution will be reduced and deposited on the surface of the steel cord to form a uniform and dense metal coating. This coating can improve the corrosion resistance, wear resistance, conductivity and other properties of the steel cord.

[0004] The composition and ratio of AQ liquid will be adjusted according to the specific electroplating requirements and process conditions. For example, factors such as the type of plating metal, the thickness of the plating, the current density, and the temperature will affect the formula of AQ liquid. At the same time, in order to ensure the stability of the electroplating process and the quality of the plating, AQ liquid also needs to be replaced or replenished regularly.

[0005] At present, a float level gauge is usually set in the water bath, and the liquid level of AQ liquid in the water bath is judged by manual inspection. However, if the manual inspection is not timely, the electroplating quality defects may be caused by the liquid level being too low. Therefore, it is very necessary to be able to detect the liquid level of AQ liquid in the water bath online. Utility Model Content

[0025] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0026] Combination Figure 1-2 As shown, the first aspect of the utility model proposes an AQ liquid level detection alarm device, including an electroplating water bath 10, a water pump 20, a monitoring circuit 30 and a water pump driving circuit 50. The electroplating water bath 10 is used to contain the electroplating liquid. Since the electroplating liquid reacts with the air and impurities are introduced during the electroplating process of the steel cord, the electroplating water bath is separated so that the steel cord is only in contact with part of the electroplating liquid. As this part of the electroplating liquid is consumed by evaporation and carry-out, its liquid level drops, and it is necessary to replenish new electroplating liquid in time to maintain its liquid level.

[0027] Specifically, the electroplating water bath 10 includes a lower tank body 101 and an upper tank body 102, the lower tank body 101 and the upper tank body 102 are isolated from each other, the upper end of the upper tank body 102 is open, the steel cord is immersed in the electroplating liquid of the upper tank body 102 and is electroplated, and the lowest liquid level in the upper tank body 102 is defined as the first height.

[0028] The water pump 20 is connected to the electroplating water bath 10, and the input end of the water pump 20 is connected to the lower tank body 101, and is used to pump water into the upper tank body 102 to maintain the liquid level in the upper tank body 102. Therefore, how to start the water pump 20 at the right time is an important means to maintain the stability of the liquid level in the upper tank body 102. In this application, timely liquid replenishment of the water pump 20 is achieved through an automated control method with online monitoring.

[0029] Furthermore, the monitoring circuit 30 includes a first electrode 31, a second electrode 32 and an electromagnetic relay 33 connected in series to the circuit; the liquid level detection component includes a metal rod 41, which is insulated and connected to the electroplating water bath 10 and extends to the upper tank body 102, and the water pump drive circuit 50 includes a relay normally open switch 51 connected in series to the circuit.

[0030] The lower end of the metal rod 41 extends to a first height, the first electrode 31 is connected to the electroplating water bath 10 , and the second electrode 32 is connected to the metal rod 41 .

[0031] In this way, when the plating liquid level in the upper tank body 102 is higher than the first height, the metal rod 41 is immersed in the plating liquid. Since the plating liquid is conductive, the monitoring circuit 30 is turned on, the electromagnetic relay 33 is energized, and the water pump drive circuit 50 is disconnected. At this time, the plating liquid level in the upper tank body 102 is in a downward trend due to consumption, until the plating liquid level in the upper tank body 102 is lower than the first height, the monitoring circuit 30 is disconnected, the electromagnetic relay 33 loses power, and the water pump drive circuit 50 is closed, so that the water pump 20 pumps liquid into the upper tank body 102, so that the plating liquid in the upper tank body 102 is maintained at a preset height.

[0032] Optionally, the water pump 20 may continue to operate for a predetermined period of time by delaying shutdown to meet the pumping liquid demand.

[0033] Combination Figure 1 As shown, the metal rod 41 includes a stainless steel rod, a thread is provided on the upper end of the stainless steel rod, a pair of nuts are provided on the thread surface, and the second electrode 32 is connected between the pair of nuts and fixed to the metal rod 41 .

[0034] Specifically, the second electrode 32 is a clamp-shaped electrode. The second electrode 32 is inserted between a pair of nuts and the nuts are tightened to ensure that the second electrode 32 is maintained stably and keeps in contact with the metal rod 41. The metal rod 41 can be a stainless steel rod.

[0035] Furthermore, a partition 12 is provided in the electroplating water bath 10, and the partition 12 is used to separate the lower tank body 101 and the upper tank body 102. Optionally, the electroplating water bath 10 is made of corrosion-resistant material, and the partition 12 is integrally formed with the electroplating water bath 10, so that the lower tank body 101 and the upper tank body 102 are isolated from each other.

[0036] Furthermore, the electroplating water bath 10 is provided with a water pump support chamber 11, which is arranged above the partition 12 and connected to the upper tank body 102. The water pump 20 is connected to the water pump support chamber 11, and a sealing tube 13 is provided below the water pump support chamber 11. The water inlet pipe of the water pump 20 extends from the sealing tube 13 to the lower tank body 101.

[0037] In this way, the water pump 20 is separated from the other parts of the water bath by the water pump support chamber 11, which can reduce the entry of heavy impurities in the upper tank body 102 into the vicinity of the water pump 20. A sealing plug is provided at the bottom of the water inlet pipe of the water pump 20, and the sealing plug and the inner wall of the sealing tube 13 are sealed and connected to avoid the lower tank body 101 and the upper tank body 102 from being connected to each other. When the water pump 20 pumps water, the plating liquid in the lower tank body 101 is pumped into the upper tank body 102, and the lower tank body 101 is replenished with liquid by the replenishing device.

[0038] Optionally, the water pump support chamber 11 is set to a conductive material, and the first electrode 31 is connected to the water pump support chamber 11, for example, by using a screw to press the first electrode 31 onto the surface of the water pump support chamber 11, that is, to achieve electrical connection with the electroplating liquid. In order to avoid the first electrode 31 and the second electrode 32 being conductive through the water pump support chamber 11, further, a fixing sleeve 42 is provided on the water pump support chamber 11, and the fixing sleeve 42 is filled with an insulating sleeve 43, and the metal rod 41 is inserted from the insulating sleeve 43 into the upper slot 102.

[0039] In this way, the insulating sleeve 43 can be used to isolate the first electrode 31 and the second electrode 32 from direct conduction, and they must be in contact through the electroplating solution.

[0040] Furthermore, the insulating sleeve 43 is elastic, and the inner diameter of the insulating sleeve 43 is smaller than the diameter of the metal rod 41. Thus, after the metal rod 41 is inserted into the insulating sleeve 43 to a predetermined depth, the height of the bottom end thereof is determined and does not change. Therefore, the user can control the insertion depth of the metal rod 41 according to actual needs, thereby achieving the purpose of adjusting the liquid level in the upper tank 102.

[0041] Preferably, the insulating sleeve 43 is a nylon sleeve.

[0042] In an optional embodiment, the cathode terminal 311 in the monitoring circuit 30 is connected to the first electrode 31 through a wire, and the anode terminal 321 in the monitoring circuit 30 is connected to the second electrode 32 through a wire.

[0043] In combination with the above embodiments, the utility model is provided with a monitoring circuit and a water pump driving circuit. The monitoring circuit uses the liquid level detection component and the conductive property of the rod electroplating liquid to realize the circuit closure, and thereby judges the electroplating liquid level in the water bath. By controlling the depth of the metal rod inserted into the water bath, the alarm liquid level height can be determined. When the liquid level is out of the height of the metal rod, the monitoring circuit is disconnected, the water pump driving circuit is started, and the pumping is completed, so that the electroplating liquid level in the water bath reaches the preset height again. Through this online measurement method, automatic liquid replenishment can be achieved.

[0044] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
