Description

Technical Field

[0001] This utility model relates to the field of dosing device technology, and in particular to a precision dosing device for scale inhibitors in circulating cooling water. Background Technology

[0002] Scale inhibitors are substances used to interfere with the formation of precipitates of sparingly soluble inorganic salts on metal surfaces. They have wide applications in boilers, heating, and pharmaceuticals. When using circulating water to cool objects, scale inhibitors need to be added to the circulating water using a dosing device to reduce the formation of precipitates on the object's surface.

[0003] However, in existing technologies, scale inhibitors are mostly added to circulating cooling water manually. It is not easy to accurately control the dosage during the addition process, which reduces the descaling effect on the circulating cooling water. Too much or too little will affect the treatment effect of the cooling water. Moreover, it is inconvenient to remove too much scale inhibitor, which not only affects the descaling effect of the cooling water, but also wastes the descaling agent. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, the scale inhibitor is mostly added to the circulating cooling water by pouring it in manually. During the pouring process, it is not easy to accurately control the dosage, which reduces the scale removal effect on the circulating cooling water. Too much or too little will affect the treatment effect of the cooling water. Moreover, adding too much scale inhibitor is inconvenient to remove, which not only affects the scale removal effect of the cooling water, but also wastes the scale inhibitor.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a scale inhibitor precision dosing device for circulating cooling water, comprising: a tank and a U-shaped plate, and further comprising:

[0006] A dosing mechanism, disposed on the inner surface of the U-shaped plate, is used to add scale inhibitors. The dosing mechanism includes:

[0007] A measuring cylinder is disposed on one side of the inner surface of the U-shaped plate, and the outer surface of the measuring cylinder is provided with graduation lines;

[0008] An adjustment mechanism, located on the outer surface of the dosing mechanism, is used to adjust the amount of scale inhibitor added.

[0009] A stirring mechanism is located at the center of the top of the tank and can be used to uniformly mix cooling water and scale inhibitor.

[0010] Preferably, the dosing facility also includes:

[0011] A connecting pipe, located at the bottom of the measuring tank, is used for conveying the scale inhibitor;

[0012] The first solenoid valve is located on the outer surface of the connecting pipe and can be used to control the flow of scale inhibitor;

[0013] A storage bucket is positioned at the top center of the U-shaped plate;

[0014] The L-shaped tube is connected at one end to the storage tank and at the other end through the U-shaped plate to the measuring tank, and is used for the transfer of scale inhibitor.

[0015] The technical effect of adopting the above-mentioned further solution is that when adding scale inhibitor, the second solenoid valve is opened, allowing the scale inhibitor to be delivered to the inside of the measuring tank through the L-shaped tube. The appropriate amount of scale inhibitor can be accurately injected through the scale line set on the outer surface of the measuring tank.

[0016] Preferably, the adjustment mechanism includes:

[0017] A recovery pipe is provided on the outer surface of the connecting pipe for the recovery of excess scale inhibitor;

[0018] A transfer tube is disposed at one end of the recycling tube;

[0019] The pump body is located at the top center of the storage tank, and the other end of the transmission pipe is connected to the pump body, which can be used to extract the scale inhibitor.

[0020] The technical effect of adopting the above-mentioned further solution is that: the pump body is turned on to draw the scale inhibitor into the storage tank, the scale inhibitor flows into the transmission pipe through the recovery pipe, and then into the storage tank through the transmission pipe. This allows for precise control of the amount of scale inhibitor in the measuring tank.

[0021] Preferably, the stirring mechanism includes:

[0022] A dual-shaft motor is located at the top center of the barrel, and a stirring rod is fixedly connected to one end of the dual-shaft motor.

[0023] Multiple connectors are disposed on the outer surface of the stirring rod. A connecting plate is movably embedded inside the connector. Multiple stirring blades are fixedly connected to the outer surface of the connecting plate for mixing cooling water and scale inhibitor.

[0024] A connecting rod is located at the other end of the dual-axis motor, and the connecting rod passes through the U-shaped plate and the storage tank;

[0025] Multiple stirring plates are disposed on the outer surface of the connecting rod and can rotate inside the storage tank for stirring the scale inhibitor.

[0026] The technical effect of adopting the above-mentioned further solution is that the centrifugal force generated by the rotation of the connecting plate and the stirring rod drives multiple stirring blades to rotate, which stirs the circulating cooling water and scale inhibitor inside the tank, improving the mixing effect of the scale inhibitor and the cooling water. The connecting rod drives multiple stirring plates to rotate inside the storage tank, stirring the scale inhibitor inside the storage tank, preventing the scale inhibitor from settling or separating, which would affect the concentration of the scale inhibitor.

[0027] Preferably, a positioning plate is fixedly embedded in the center of the barrel, and the stirring rod is movably embedded inside the positioning plate.

[0028] The technical effect of adopting the above-mentioned further solution is that the positioning plate can improve the stability of the stirring rod.

[0029] Preferably, a second solenoid valve is provided on the outer surface of the L-shaped tube.

[0030] The technical effect of adopting the above-mentioned further solution is that opening the second solenoid valve allows the scale inhibitor to be delivered to the inside of the measuring tank through the L-shaped tube.

[0031] Preferably, a feed pipe is provided at the top of the storage tank.

[0032] The technical advantage of adopting the above-mentioned further solution is that the scale inhibitor can be injected into the interior of the storage tank through the feed pipe.

[0033] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0034] 1. In this utility model, when adding scale inhibitor, the second solenoid valve is opened, allowing the scale inhibitor to be transported into the volumetric tank through the L-shaped tube. The appropriate amount of scale inhibitor can be accurately injected through the scale lines set on the outer surface of the volumetric tank. The appropriate amount of scale inhibitor is first stored inside the volumetric tank. The second solenoid valve is closed, and the first solenoid valve is opened to transport the scale inhibitor inside the volumetric tank through the connecting pipe to the inside of the tank body to mix with the circulating cooling water. When the amount of scale inhibitor injected into the volumetric tank is large, the pump body is turned on to draw the scale inhibitor into the storage tank. The scale inhibitor flows into the transmission pipe through the recovery pipe, and then into the storage tank through the transmission pipe. This allows for precise control of the amount of scale inhibitor inside the volumetric tank and convenient and quick adjustment of the scale inhibitor.

[0035] 2. In this utility model, the dual-shaft motor drives the stirring rod and connecting rod to rotate simultaneously. Multiple connectors are fixedly installed on the outer surface of the stirring rod, and connecting plates are rotatably installed inside the connectors. The centrifugal force generated by the rotation of the stirring rod drives multiple stirring blades to rotate, stirring the circulating cooling water and scale inhibitor inside the tank, thereby improving the mixing effect of the scale inhibitor and cooling water. The stirring rod is movably embedded inside the positioning plate, which can improve the stability of the stirring rod. The connecting rod passes through the U-shaped plate and the storage tank, driving multiple stirring plates to rotate inside the storage tank, stirring the scale inhibitor inside the storage tank, preventing the scale inhibitor from settling or stratifying, which would affect the concentration of the scale inhibitor.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, as Figures 1 to 4 As shown, this utility model provides a precision dosing device for scale inhibitors in circulating cooling water, comprising: a tank body 1, a U-shaped plate 101, a dosing mechanism, an adjusting mechanism, and a stirring mechanism. The dosing mechanism includes: a measuring tank 113 disposed on one side of the inner surface of the U-shaped plate 101, with graduation lines 114 on its outer surface, allowing precise control of the amount of scale inhibitor added. A connecting pipe 110 for conveying the scale inhibitor is located at the bottom of the measuring tank 113, and a first solenoid valve 112 is located on the outer surface of the connecting pipe 110 for controlling the flow of the scale inhibitor. A storage tank 103 is located at the top center of the U-shaped plate 101, with one end of an L-shaped pipe 107 connected to the storage tank 103 and the other end passing through the U-shaped plate 101 and connected to the measuring tank 113 for conveying the scale inhibitor.

[0045] In practical applications, when scale inhibitor needs to be added, the second solenoid valve 108 is opened, allowing the scale inhibitor to be delivered to the inside of the measuring tank 113 through the L-shaped tube 107. The appropriate amount of scale inhibitor can be accurately injected through the scale line 114 set on the outer surface of the measuring tank 113. The appropriate amount of scale inhibitor is first stored inside the measuring tank 113. The second solenoid valve 108 is closed, and the first solenoid valve 112 is opened to deliver the scale inhibitor inside the measuring tank 113 to the inside of the tank body 1 through the connecting pipe 110 to mix with the circulating cooling water.

[0046] Example 2, as Figures 1 to 4 As shown, the regulating mechanism includes: a transmission pipe 106 is fixedly connected to the input end of the pump body 105, the other end of the transmission pipe 106 is connected to the recovery pipe 111, the upper end of the connecting pipe 110 is fixedly connected to the recovery pipe 111, the pump body 105 can draw the scale inhibitor through the recovery pipe 111 into the inside of the transmission pipe 106, and then recover it into the inside of the storage tank 103 through the transmission pipe 106. A feed pipe 104 is fixedly installed on the top of the storage tank 103, and the scale inhibitor can be injected into the inside of the storage tank 103 through the feed pipe 104.

[0047] In this embodiment, when the amount of scale inhibitor injected into the measuring tank 113 is large, the pump body 105 is turned on to draw the scale inhibitor into the storage tank 103. The scale inhibitor flows into the transmission pipe 106 through the recovery pipe 111, and then into the storage tank 103 through the transmission pipe 106. This allows for precise control of the amount of scale inhibitor in the measuring tank 113, and makes it convenient and quick to adjust the scale inhibitor.

[0048] Example 3, as Figures 1 to 4 As shown, the stirring mechanism includes: multiple stirring plates 120 fixedly installed on the outer surface of the connecting rod 109, the stirring plates 120 being movably embedded inside the storage tank 103, which can stir the scale inhibitor inside the storage tank 103; a stirring rod 115 being movably embedded inside the tank body 1, multiple connectors 119 fixedly installed on the outer surface of the stirring rod 115, and connecting plates 116 being movably embedded inside each of the multiple connectors 119; multiple stirring blades 117 fixedly installed on the outer surface of the connecting plates 116; the stirring rod 115 drives the multiple connecting plates 116 to rotate through the connectors 119; under the action of centrifugal force, the connecting plates 116 drive the stirring blades 117 to stir the circulating cooling water and scale inhibitor inside the tank body 1, thereby improving the mixing effect of the scale inhibitor and the cooling water; and the stirring rod 115 being movably embedded inside the positioning plate 118, which can improve the stability of the stirring rod 115.

[0049] In this embodiment, the dual-axis motor 102 is turned on to drive the stirring rod 115 and the connecting rod 109 to rotate simultaneously. Multiple connectors 119 are fixedly installed on the outer surface of the stirring rod 115. A connecting plate 116 is rotatably installed inside the connector 119. The centrifugal force generated by the rotation of the stirring rod 115 drives multiple stirring blades 117 to rotate, stirring the circulating cooling water and scale inhibitor inside the tank 1, improving the mixing effect of the scale inhibitor and the cooling water. The stirring rod 115 is movably embedded inside the positioning plate 118, which can improve the stability of the stirring rod 115. The connecting rod 109 passes through the U-shaped plate 101 and the storage tank 103, driving multiple stirring plates 120 to rotate inside the storage tank 103, stirring the scale inhibitor inside the storage tank 103, preventing the scale inhibitor from precipitating or stratifying, which would affect the concentration of the scale inhibitor.

[0050] Working principle: When adding scale inhibitor, the second solenoid valve 108 is opened, allowing the scale inhibitor to be delivered to the inside of the measuring tank 113 through the L-shaped tube 107. The appropriate amount of scale inhibitor can be accurately injected through the scale line 114 set on the outer surface of the measuring tank 113. The appropriate amount of scale inhibitor is first stored inside the measuring tank 113. The second solenoid valve 108 is closed, and the first solenoid valve 112 is opened to deliver the scale inhibitor inside the measuring tank 113 to the inside of the tank body 1 through the connecting pipe 110 to mix with the circulating cooling water.

[0051] When the amount of scale inhibitor injected into the measuring tank 113 is large, the pump body 105 is turned on to draw the scale inhibitor into the storage tank 103. The scale inhibitor flows into the transmission pipe 106 through the recovery pipe 111, and then into the storage tank 103 through the transmission pipe 106. This allows for precise control of the amount of scale inhibitor in the measuring tank 113 and convenient and quick adjustment of the scale inhibitor.

[0052] The dual-shaft motor 102 is turned on, driving the stirring rod 115 and the connecting rod 109 to rotate simultaneously. Multiple connectors 119 are fixedly installed on the outer surface of the stirring rod 115. A connecting plate 116 is rotatably installed inside the connector 119. The centrifugal force generated by the rotation of the stirring rod 115 drives multiple stirring blades 117 to rotate, stirring the circulating cooling water and scale inhibitor inside the tank 1, improving the mixing effect of the scale inhibitor and cooling water. The stirring rod 115 is movably embedded inside the positioning plate 118, which can improve the stability of the stirring rod 115. The connecting rod 109 passes through the U-shaped plate 101 and the storage tank 103, driving multiple stirring plates 120 to rotate inside the storage tank 103, stirring the scale inhibitor inside the storage tank 103, preventing the scale inhibitor from settling or stratifying, which would affect the concentration of the scale inhibitor.
