[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of this specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] To solve the above problems, please refer to Figures 1 to 3 , the present utility model provides an aqueous solution flow reduction alarm device for monitoring the flow of the added solution, which includes a flow monitoring structure 1, a collection tank 2, an alarm structure 3 and a control structure 4. The flow monitoring structure 1 is used to monitor the change of the added solution flow. The flow monitoring structure 1 includes a detection component 11 and an overflow tank 12. The detection component 11 is arranged on the periphery of the overflow tank 12 and is perpendicular to the overflow tank 12. A closed loop is formed between the overflow tank 12 and the detection component 11 through an added solution liquid column 5. The overflow tank 12 has an opening 121 and a through hole 122. The added solution enters the overflow tank 12 from the opening 121. The through hole 122 is opened at the bottom of the overflow tank 12, and the opening degree of the through hole 122 is adjusted by an adjusting member 6 to adjust the thickness of the added solution liquid column 5. The collection tank 2 has a receiving cavity 21. The flow monitoring structure 1 is arranged in the receiving cavity 21. The collection tank 2 is used to collect the added solution passing through the through hole 122 and the detection component 11 and is transported to the processing equipment through a pipeline. The alarm structure 3 gives an audible and visual warning according to the connection situation between the overflow tank 12 and the detection component 11. The control structure 4 is electrically connected to the overflow tank 12, the detection component 11 and the alarm structure 3. The control structure 4 receives the electrical signals generated by the closed loop of the overflow tank 12 and the detection component 11 and transmits the electrical signals to the alarm structure 3. Among them, the collection tank 2 is provided with an operation window corresponding to the overflow tank 12, and the staff can adjust, replace or maintain the adjusting member 6, the detection component 11, etc. through this operation window.

[0029] In an alternative embodiment, as Figure 1 shown, the overflow tank 12 is provided with a drainage member 123. The drainage member 123 is communicated with the overflow tank 12 and is arranged lower than the opening 121. The drainage member 123 is used to drain the added solution to form a liquid column 5 and establish a closed loop with the detection component 11. Specifically, the overflow tank 12 is provided with an overflow port 124. The drainage member 123 is welded to the overflow port 124. Part of the added solution overflows from the overflow port 124, and the overflowed added solution is drained to the contact piece 112 through the drainage member 123. Further, the cross section of the drainage member 123 is in a "V" shape, and the size of the drainage member 123 gradually decreases from the overflow port 124 towards the contact piece 112, which is convenient for collecting the overflowed added solution to form the smallest liquid column 5 that can be detected.

[0030] In an alternative embodiment, as Figure 1As shown, the drainage member 123 is inclined towards the lower point of the detection assembly 11. The inclined setting of the drainage member 123 can cause the overflowed additive solution to quickly flow towards the contact piece 112, avoiding the discontinuity of the liquid column 5 and improving the detection accuracy of the flow monitoring structure 1.

[0031] In an alternative embodiment, as Figure 1 shown, an insulating bracket 7 is provided on the peripheral side of the overflow tank 12. One end of the insulating bracket 7 away from one end of the overflow tank 12 is provided with a clamping portion for clamping the detection assembly 11. The setting of the insulating bracket 7 can prevent the detection assembly 11 from directly contacting the overflow tank 12 and affecting the detection effect. Moreover, by providing the clamping portion, the depth of the detection electrode 111 extending into the collection tank 2 can be flexibly adjusted. The insulating bracket 7 can be made of food-grade insulating hard plastic materials such as polypropylene and polystyrene, having good hardness and insulating properties.

[0032] In an alternative embodiment, as Figures 1 to 3 shown, the detection assembly 11 includes a detection electrode 111 and a contact piece 112. The contact piece 112 is disposed at one end of the detection electrode 111 extending into the collection tank 2. The contact piece 112 is inclined towards the pipeline and guides the additive solution to be close to the pipeline. Both the detection electrode 111 and the contact piece 112 are made of metal materials and have good electrical conductivity. The contact piece 112 is connected to the detection electrode 111 by welding. The other end of the detection electrode 111 is connected to a wire and electrically connected to the control structure 4, having good connection stability. Due to the large contact surface of the contact piece 112, it can contact the additive solution liquid column 5 in a large range. At the same time, the inclined setting of the contact piece 112 can guide the overflowed additive solution to the pipeline, facilitating the collection tank 2 to concentrate and transport it into the processing equipment through the pipeline.

[0033] In an alternative embodiment, as Figure 1 shown, the adjusting member 6 includes an adjusting valve piece 61 and a screw 62. The adjusting valve piece 61 is disposed at the bottom of the overflow tank 12 and is sequentially passed through the overflow tank 12 and the adjusting valve piece 61 by the screw 62 and locked by a nut. The adjusting valve piece 61 protrudes from the bottom of the overflow tank 12 and rotates along the central axis of the screw 62 for adjusting the opening degree of the through hole 122. By manually adjusting the way to rotate the adjusting valve piece 61, partially covering the through hole 122, further adjusting the thickness of the additive solution liquid column 5 flowing from the guiding member to the detection assembly 11, so that the liquid column 5 is in a continuously flowing and detectable minimum liquid column 5 state, and the overflow tank 12 and the detection assembly 11 are always in a closed circuit state.

[0034] In an alternative embodiment, as Figure 1As shown, the collecting box 2 is provided with a mounting bracket 22 for mounting the flow monitoring structure 1. The mounting bracket 22 is made of metal, and one end of the mounting bracket 22 is connected to the inner wall of the collecting box 2 by welding, and the other end is connected to the outer wall of the overflow tank 12, which has good connection strength, can prevent the overflow tank 12 from shaking, and improve the connection stability.

[0035] In an alternative embodiment, as Figure 2 and Figure 3 shown, the alarm structure 3 includes an indicator light 31 and an audible and visual alarm 32. The indicator light 31 is used for flashing lights, and the audible and visual alarm 32 is used for emitting alarm sounds.

[0036] In an alternative embodiment, as Figure 2 and Figure 3 shown, the control structure 4 includes a liquid level relay 41 and an intermediate relay 42. The liquid level relay 41 is electrically connected to the flow monitoring structure 1 for receiving flow change information, and the intermediate relay 42 is electrically connected to the liquid level relay 41 for controlling the alarm structure 3. Specifically, when a closed circuit state is formed between the overflow tank 12 and the detection component 11, the signal of the closed circuit is transmitted to the signal input end of the liquid level relay 41 through a wire, triggering the liquid level relay 41 to be in an initial state, and its normally open contact is in an open state. When the flow rate of the added solution decreases, the drainage member 123 will have a discontinuous liquid column 5 or a complete interruption of the flow, resulting in the disconnection of the circuit loop between the detection component 11 and the overflow tank 12, triggering the normally open contact of the liquid level relay 41 to close, further driving the intermediate relay 42 to operate, so that the multiple normally open contacts of the intermediate relay 42 close, driving the indicator light 31 and the audible and visual alarm 32 to respectively emit audible and visual prompts to remind the operator to check and handle the problem of reduced flow.

[0037] In a specific embodiment, each adding device is provided with a flow monitoring structure, a collecting box 2, an alarm structure 3 and an intermediate relay 42. Each flow monitoring structure is connected in parallel and is connected to the corresponding signal input end of the liquid level relay 41, and the alarm structure 3 is controlled by the corresponding intermediate relay 42 to emit an alarm when the added solution decreases, so that the staff can quickly identify which adding device is abnormal and then go to deal with it.

[0038] In summary, by monitoring the on-off of the circuit between the detection component 11 and the overflow tank 12, it is judged whether the liquid column 5 between the detection component 11 and the overflow tank 12 is continuous. When the liquid column 5 has a discontinuous liquid column 5 or a complete interruption of the flow, the control structure 4 controls the alarm structure 3 to emit audible and visual prompts, reminding the staff to go to the adding device corresponding to the alarm structure 3 to check and handle the problem of reduced flow, eliminating the need for the staff to constantly monitor the flow rate of the adding device and improving work efficiency.
