Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger accessories, and in particular to a sacrificial anode structure. Background Art

[0002] Existing heat exchangers usually use the method of setting sacrificial anodes to prevent the metal liner from being corroded, that is, a metal with stronger activity than the metal liner to be protected is connected to prevent the electrolyte from corroding the liner and pipelines. According to the principle of electrochemistry, because the anode material has a relatively negative body potential, it will provide cathode current to the protected steel structure through the electrolyte in the liquid, so that the protected steel structure is cathodized and does not rust. As the current continues to flow, while preventing the liner from rusting, the anode material itself is also continuously consumed. When the anode material is exhausted, the steel (not limited to steel, such as copper, etc.) liner loses protection and then quietly begins to corrode. It can be seen that timely replacement and replenishment of anode materials and anodes are crucial.

[0003] The prior art has the following deficiencies: Regarding the replacement of sacrificial anodes in existing heat exchangers, the replacement time of the sacrificial anodes is usually stated in the instructions of the heat exchanger. However, when the sacrificial anodes of the heat exchanger reach the replacement time, since the sacrificial anodes themselves have no reminder function, users often forget to replace the severely corroded sacrificial anodes, which causes the inner tank of the heat exchanger to begin to corrode, thereby causing serious losses.

[0004] Therefore, there is an urgent need for a sacrificial anode structure with a prompting function to solve the above problems. Summary of the invention

[0005] The present invention aims at solving the deficiencies of the prior art and provides a sacrificial anode structure.

[0006] The present invention solves the above technical problems through the following technical means: a sacrificial anode structure, including an anode body, a sleeve is arranged on the outside of the anode body, a base is fixedly arranged on the top of the sleeve, and the anode body is threadedly connected to the base and then inserted into the sleeve, a first switch is embedded in the inner wall of the sleeve, a button battery and an LED lamp are detachably arranged on one side of the top of the base, and the anode body is abutted against the first switch, the first switch, the button battery and the LED lamp are connected in series, the anode body is corroded and does not contact the first switch, the first switch connects the current between the button battery and the LED lamp, and the LED lamp lights up for prompting.

[0007] Preferably, a buzzer is provided on one side of the LED lamp, and the buzzer is connected in series with the first switch and the button battery, and the buzzer is connected in parallel with the LED lamp. When the first switch is not pressed, the buzzer and the LED lamp operate simultaneously to emit sound and light prompts. When either the buzzer or the LED lamp is damaged, the normal use of the other is not affected.

[0008] Preferably, a second switch is further provided on the side of the inner wall of the sleeve away from the first switch, the second switch corresponds to the position of the first switch, and the first switch and the second switch are connected in series. In order to avoid local corrosion of the anode body causing the first switch to be unpressed and issue a prompt, providing a second switch corresponding to the position of the first switch can effectively solve this problem. When the corrosion length of the anode body exceeds a threshold, the second switch and the first switch are not pressurized at the same time, and the button battery supplies power to the buzzer and the LED lamp. When either the second switch or the first switch continues to be pressurized, the button battery does not supply power to the buzzer and the LED lamp, thereby avoiding false prompts.

[0009] Preferably, in the actual practical process, the length threshold of the anode body being corroded is different according to the inner tank material of the heat exchanger and the actual length of the anode body. Therefore, in order to facilitate the adjustment of the prompt threshold, we make the following scheme:

[0010] Preferably, an adjustment component is provided in the sleeve, the adjustment component includes a circular ring frame, a slide rod, a spring and a limit plate, and the two slide rods are fixedly arranged on the top of the first switch and the second switch respectively, the circular ring frame is fixed to the top of the slide rod, and the circular ring frame is slidably embedded in the base, the spring is embedded in the first slide groove of the inner wall of the sleeve, the limit plate is fixed to the outer side of the middle part of the slide rod, and the top of the spring abuts against the limit plate;

[0011] Preferably, a screw is further provided on the side of the top of the base away from the LED lamp, and the screw is threadedly connected to the base, and the bottom end of the screw is in contact with the circular frame;

[0012] Preferably, the screw rotates clockwise and downward, thereby pushing the circular ring frame downward, and the circular ring frame drives the first switch and the second switch to move downward in the second slide groove of the inner wall of the sleeve through the sliding rod. At this time, the corrosion length threshold of the anode body is reduced, and the screw rotates counterclockwise and upward, the circular ring frame is not restricted, and the spring drives the sliding rod to move upward through the limit plate, and the sliding rod drives the first switch and the second switch to move upward in the second slide groove of the inner wall of the sleeve. At this time, the corrosion length threshold of the anode body increases; the present application can adjust the corrosion length threshold, so that the structure can adapt to different types of heat exchangers.

[0013] Beneficial effects of the present invention:

[0014] 1. When the anode body of the present invention is inserted into the sleeve, the first switch is pressed. When the first switch is pressed, the button battery stops supplying power to the LED lamp. When the corrosion length of the anode body exceeds the first switch, the first switch is not pressed, the button battery supplies power to the LED lamp, and the LED lamp is powered on to light up to prompt replacement. This structure can prompt the user to replace the anode body after the corrosion of the anode body exceeds a certain length, thereby effectively protecting the inner tank of the heat exchanger.

[0015] 2. The present invention pushes the circular ring frame downward by rotating the screw clockwise, and the circular ring frame drives the first switch and the second switch to move downward in the second slide groove of the inner wall of the sleeve through the slide rod. At this time, the corrosion length threshold of the anode body is reduced, and the screw rotates counterclockwise and upward, the circular ring frame is not restricted, and the spring drives the slide rod upward through the limit plate, and the slide rod drives the first switch and the second switch to move upward in the second slide groove of the inner wall of the sleeve. At this time, the corrosion length threshold of the anode body increases. The present application can adjust the corrosion length threshold, so that the structure can adapt to different types of heat exchangers. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In actual practical application, the length threshold of the anode body 1 being corroded is different according to the inner tank material of the heat exchanger and the actual length of the anode body 1. Therefore, in order to facilitate the adjustment of the prompt threshold, we make the following plan:

[0034] An adjustment assembly 8 is provided in the sleeve 2, and the adjustment assembly 8 includes a circular ring frame 81, a slide bar 82, a spring 83 and a limit plate 84, and the two slide bars 82 are fixedly arranged on the top of the first switch 3 and the second switch 7 respectively, the circular ring frame 81 is fixed to the top of the slide bar 82, and the circular ring frame 81 is slidably embedded in the base 21, the spring 83 is embedded in the first slide groove 22 of the inner wall of the sleeve 2, the limit plate 84 is fixed to the outer middle part of the slide bar 82, and the top of the spring 83 is in contact with the limit plate 84;

[0036] The screw rod 9 rotates clockwise and downward, thereby pushing the circular frame 81 downward, and the circular frame 81 drives the first switch 3 and the second switch 7 to move downward in the second slide groove 23 on the inner wall of the sleeve 2 through the slide rod 82. At this time, the corrosion length threshold of the anode body 1 decreases, and the screw rod 9 rotates counterclockwise and upward, the circular frame 81 is not restricted, and the spring 83 drives the slide rod 82 upward through the limit plate 84. The slide rod 82 drives the first switch 3 and the second switch 7 to move upward in the second slide groove 23 on the inner wall of the sleeve 2. At this time, the corrosion length threshold of the anode body 1 increases;

[0037] The present application can adjust the corrosion length threshold, thereby facilitating the structure to adapt to different models of heat exchangers.
