Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment softening and hardening device. Background Technology

[0002] In the field of water treatment technology, water softening and hardness removal are key components in industrial circulating water systems, heating systems, and domestic water supply systems. The core purpose is to reduce hardness components such as calcium and magnesium ions in the water, reduce scale formation, and avoid problems such as pipe blockage, reduced equipment efficiency, and increased energy consumption.

[0003] Currently, commonly used water treatment softening and hardening technologies mainly include ion exchange, membrane separation, and chemical additives. Ion exchange softens water by adsorbing calcium and magnesium ions through resin, but it suffers from problems such as frequent resin regeneration, high cost of regenerated solution treatment, and susceptibility to secondary pollution. Membrane separation (such as reverse osmosis) can efficiently remove hardness, but it requires large equipment investment, is prone to membrane clogging, and has high maintenance costs, making it difficult to widely apply in small and medium-sized circulating water systems.

[0004] Chemical additive methods (such as adding scale inhibitors) have become the mainstream choice for industrial circulating water systems due to their ease of operation and low cost. However, existing scale inhibitor addition devices have significant drawbacks: First, most adopt a continuous addition method, which easily leads to the formation of local high-concentration areas of scale inhibitor near the addition point, while the concentration of scale inhibitor in the water further away is insufficient, resulting in uneven hardness removal effect; Second, some devices require system shutdown to complete the addition, affecting the continuity of production; Third, the mixing of the agent and the water depends on natural convection, resulting in low mixing efficiency, which further affects the hardness removal effect.

[0005] Therefore, it is necessary to provide a new water treatment softening and hardening device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a water treatment softening and hardening device.

[0007] The water treatment softening and hardening device provided by this utility model includes a central connecting pipe, an additive pipe is fixedly installed on the central connecting pipe, and a horizontally arranged liquid guide pipe is fixedly installed on the additive pipe. The connection between the additive pipe and the liquid guide pipe forms a liquid outlet, and a piston column for sealing the liquid outlet is installed inside the additive pipe. The additive tube is equipped with an opening and closing component for driving the piston column to open and close the liquid outlet, and the opening and closing component includes a connecting rod, which is fixedly installed on the lower cylindrical surface of the piston column, and a rotatably connected steel ball is installed at the bottom of the connecting rod. The central connecting pipe is equipped with a drive component for raising and lowering the connecting rod.

[0008] Preferably, the opening and closing component further includes a spring, one end of which is fixedly mounted on the lower cylindrical surface of the piston rod, and the other end of which is fixedly mounted on a limiting bracket that is fixedly fitted inside the additive tube.

[0012] Preferably, both ends of the central connecting pipe are fixedly installed with connecting flanges.

[0013] Preferably, a control valve is installed on the liquid guide tube.

[0014] Compared with related technologies, the water treatment softening and hardening removal device provided by this utility model has the following beneficial effects: This invention enables the scale inhibitor to flow dynamically and intermittently into the central pipe through the cooperation of the piston column, opening and closing components, and driving components.

Furthermore, the liquid cooling circulating water system does not need to be shut down when adding scale inhibitor. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 3 This utility model provides a water treatment softening and hardening device, which includes a central connecting pipe 1, an additive pipe 2, a piston column 3, an opening and closing component 4, and a driving component 5.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 3 Both ends of the central connecting pipe 1 are fixedly installed with connecting flanges 11. An additive pipe 2 is fixedly installed on the central connecting pipe 1, and a horizontally arranged liquid guide pipe 21 is fixedly installed on the additive pipe 2. A control valve (not shown in the figure) is installed on the liquid guide pipe 21. The connection between the additive pipe 2 and the liquid guide pipe 21 forms a flow port. A piston rod 3 for sealing the flow port is installed inside the additive pipe 2. An opening / closing component 4 for driving the piston rod 3 to open and close the flow port is installed inside the additive pipe 2. The opening / closing component 4 includes a connecting rod 41, which is fixedly installed on the lower cylindrical surface of the piston rod 3. A valve is installed at the bottom of the connecting rod 41. The rotating connection is made of steel ball 42, and the opening and closing component 4 also includes spring 43. One end of spring 43 is fixedly installed on the lower cylinder surface of piston column 3, and the other end of spring 43 is fixedly installed on the limiting frame 22 fixedly fitted inside the additive tube 2. The central connecting tube 1 is equipped with a drive component 5 for lifting and lowering the connecting rod 41. The drive component 5 includes a rotating shaft 51, which is radially arranged inside the central connecting tube 1 and rotatably connected to the central connecting tube 1. A cam 53 is fixedly sleeved on the rotating shaft 51. Impellers 52 are fixedly sleeved on the rotating shafts 51 on both sides of the cam 53. The outer ring wall of the cam 53 abuts against the steel ball 42.

[0021] It should be noted that: the central connecting pipe 1 is connected to the pipeline of the circulating cooling water system, and the liquid guide pipe 21 is connected to the drain pipe of the scale inhibitor storage tank. When scale inhibitor needs to be added to the circulating cooling water, the control valve is opened. When the circulating cooling water enters the central connecting pipe 1, the water impacts the drive component 5, thereby the drive component 5 drives the connecting rod 41 to reciprocate up and down. When the water drives the impeller 52 to rotate, the shaft 51 drives the cam 53 to rotate. When the protrusion of the cam 53 abuts against the steel ball 42, the connecting rod 41 pushes the piston 3 upward, causing the piston 3 to slide past the liquid outlet (at this time, the spring 43 is stretched). Therefore, the scale inhibitor flows from the liquid outlet into the additive pipe 2 and is injected into the central connecting pipe 1 from the additive pipe 2. The rotating impeller 52 enhances the mixing effect of the scale inhibitor and this part of the circulating liquid. When the protrusion of the cam 53 rotates away from the steel ball 42, the piston rod 3 returns to its original position and seals the liquid outlet under the action of the spring force of the spring 43, thus suspending the addition of scale inhibitor to the central connecting pipe 1.

[0022] This application enables the scale inhibitor to flow dynamically and intermittently into the central connecting pipe 1 through the cooperation of the piston column 3, the opening and closing component 4, and the driving component 5. This avoids the problem of excessively high local liquid cooling circulating water concentration and insufficient scale inhibitor concentration in the remote liquid cooling circulating water caused by continuous addition of scale inhibitor. Furthermore, the liquid cooling circulating water system does not need to be shut down when adding scale inhibitor.

[0023] An air valve 6 is fixedly installed at the top of the additive tube 2 to prevent negative pressure or excessive air pressure at the top of the additive tube 2.

[0024] To eliminate the potential for spring 43 to rust and lose its elasticity due to contact with coolant, spring 43 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 43 to enhance its rust prevention capability.

[0025] The working principle of the water treatment softening and hardening removal device provided by this utility model is as follows: Connect the central connecting pipe 1 to the pipeline of the circulating cooling water system, and connect the liquid guide pipe 21 to the drain pipe of the scale inhibitor storage tank. When scale inhibitor needs to be added to the circulating cooling water, open the control valve. When the circulating cooling water enters the central connecting pipe 1, the water impacts the drive component 5, thereby driving the connecting rod 41 to reciprocate. When the water drives the impeller 52 to rotate, the rotating shaft 51 drives the cam 53 to rotate. When the protrusion of the cam 53 abuts against the steel ball 42, the connecting rod 41 pushes the piston 3 upward, causing the piston 3 to slide past the liquid outlet (at this time, the spring 43 is stretched). Therefore, the scale inhibitor flows from the liquid outlet into the additive pipe 2 and is added by the additive. The scale inhibitor is injected into the central connecting pipe 1 through pipe 2. The rotating impeller 52 enhances the mixing effect between the scale inhibitor and the circulating fluid in this part. When the protrusion of the cam 53 rotates away from the steel ball 42, the piston column 3 is reset and the flow port is sealed under the action of the spring 43, thus pausing the addition of scale inhibitor to the central connecting pipe 1. This application enables the scale inhibitor to flow into the central connecting pipe 1 dynamically and intermittently through the cooperation of the piston column 3, the opening and closing component 4 and the driving component 5. This avoids the problem of excessively high local liquid cooling circulating water concentration and insufficient scale inhibitor concentration in the far-end liquid cooling circulating water caused by continuous addition of scale inhibitor. Moreover, the liquid cooling circulating water system does not need to be shut down when adding scale inhibitor.
