Description

Technical Field

[0001] This utility model relates to the field of seed crystal dosing devices, specifically a non-powered seed crystal dosing device for a softened water treatment system. Background Technology

[0002] In industrial boilers, circulating cooling water systems, a "softening treatment with seed crystals as carriers" process is often used. This involves adding tiny seed crystals (such as calcium carbonate crystals) to the reactor to provide crystallization nuclei for supersaturated scale-forming substances (such as calcium carbonate) in the water. This causes the scale to precipitate on the surface of the seed crystals instead of forming scale on the pipes and equipment walls, thereby achieving the purpose of softening the water.

[0003] In existing technologies, seed crystal addition is mostly achieved through power delivery methods, such as using small delivery pumps or pneumatic delivery devices. These methods have drawbacks, such as requiring additional power supplies and control units, increasing system complexity and manufacturing costs; high failure rates of electrical equipment and inconvenient maintenance in humid or corrosive environments; and difficulty in consistently controlling the addition rate, with pump start-ups and shutdowns easily causing interruptions or overdosing. Therefore, there is an urgent need for a device with a simple structure, requiring no external power, and capable of continuous and stable seed crystal addition. Utility Model Content

[0004] The purpose of this invention is to provide a non-powered seed crystal dosing device for a softened water treatment system, which has the advantages of simple structure, no power required, reliable operation, and convenient maintenance, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-powered seed crystal dosing device for a softened water treatment system, comprising a discharge shell, a buoyancy cavity formed on the discharge shell, and a discharge chamber formed on the other side of the buoyancy cavity. The buoyancy cavity and the discharge chamber are separated by a baffle. It also includes a support column, which is disposed at the bottom of the inner wall of the buoyancy cavity. A lever is installed on the end of the support column away from the buoyancy cavity, one end of the lever extends into the discharge chamber, and a sealing plug is installed on the end of the lever extending into the discharge chamber. A clamp is installed on the end of the lever near the sealing plug, and a float is adhered to the clamp. The float is suspended in the buoyancy cavity. The float, as the water level in the buoyancy cavity rises and falls, pries the lever, causing the sealing plug to rise and fall, controlling the discharge of the discharge chamber.

[0006] Furthermore, a discharge port is provided at the bottom of the inner wall of the discharge chamber at the corresponding position of the sealing plug. The discharge port is integrally formed with the inner wall of the discharge chamber. When the sealing plug rises, the material accumulated in the discharge chamber can flow into the reactor from the discharge port.

[0007] Furthermore, a flange is installed between the sealing plug and the lever, and the sealing plug is connected to the lever through the flange.

[0008] Furthermore, a counterweight is installed on the end of the lever away from the flange. The counterweight is bolted to the lever. The counterweight can adjust the balance of weight at both ends of the lever. Since the counterweight is bolted to the lever, it can be removed and replaced with counterweights of different weights.

[0009] Furthermore, an overflow trough is provided at the bottom of the inner wall of the buoyancy cavity. The overflow trough penetrates the inner wall of the buoyancy cavity. The overflow trough is provided so that when the discharge shell is installed at the upper inlet position of the reactor, the water level in the reactor rises, and the water enters the buoyancy cavity through the overflow trough, so that the float rises with the liquid level.

[0010] Furthermore, the outer surface of the lever is provided with multiple bolt holes, which can be used to adjust the length of the lever arm at one end.

[0011] Furthermore, connecting blocks are installed around the outer surface of the material feeding shell.

[0012] Furthermore, a rubber anti-slip strip is installed on the outer surface of the float. The rubber anti-slip strip can make the rubber anti-slip strip contact the inner wall of the tight band when the float is stuck in the tight band, thereby increasing the firmness of the connection between the float and the tight band.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a discharge assembly housed within the discharge shell. The entire assembly consists of only three mechanical parts, requiring no external power or control circuitry. It is driven purely by buoyancy changes caused by liquid level variations, resulting in extremely high reliability. The addition of seed crystals is directly linked to the reactor liquid level. Addition only occurs when the water level reaches the required working level; it automatically stops when the water level drops, perfectly matching the system's operating conditions. All components are common mechanical parts, making them inexpensive. In case of malfunction, the cause is immediately apparent, and the corresponding component can be directly replaced.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To address the shortcomings of existing technologies that primarily rely on power-driven delivery methods, such as small pumps or pneumatic conveying devices, for seed crystal addition, which have drawbacks such as requiring additional power supplies and control units, increasing system complexity and manufacturing costs; high electrical equipment failure rates and inconvenient maintenance in humid or corrosive environments; and difficulty in consistently controlling the addition rate, with pump start-stop operations easily causing interruptions or over-addition, this embodiment provides the following technical solution: Example 1: As Figures 1-5 As shown, the device includes a discharge housing 1, which is made of UPVC or stainless steel and has good corrosion resistance. Inside the discharge housing 1, a partition separates a buoyancy chamber 2 and a discharge chamber 3. A support column 6 is located at the bottom of the buoyancy chamber 2, and a lever 7, made of 304 stainless steel, is mounted on the support column 6. One end of the lever 7 is fixedly connected to a float 11 via a clamp 10. The float 11 is a hollow polypropylene float or a hollow stainless steel float, and its outer surface is provided with rubber anti-slip strips 15 to increase the connection strength with the clamp 10. The other end of the lever 7 extends into the discharge chamber 3 and is connected to a sealing plug 13 via a flange 12. The sealing plug 13 is made of silicone rubber or fluororubber and has good sealing performance and corrosion resistance. A discharge port 14 is located at the bottom of the discharge chamber 3, directly opposite the sealing plug 13.

[0018] During operation, the device is installed above the reactor inlet via connecting blocks 4 around its perimeter. As the water level in the reactor rises, water flows into the buoyancy chamber 2 through the overflow trough 5 at the bottom. With the rising water level in the buoyancy chamber 2, the float 11 rises due to buoyancy, causing the lever 7 to rotate around the fulcrum of the support column 6 via the clamping band 10. The other end of the lever 7 causes the sealing plug 13 to rise, thus opening the discharge port 14. The pre-filled seed crystal material in the discharge chamber 3 falls into the reactor through the discharge port 14 under gravity, achieving the addition of the seed crystals. When the water level in the reactor drops, the water level in the buoyancy chamber 2 also drops through the overflow trough 5. The buoyancy of the float 11 decreases, and under the action of the counterweight 8 at the other end of the lever 7, the lever 7 rotates in the opposite direction, pushing the sealing plug 13 down and resealing the discharge port 14, stopping the addition.

[0019] Example 2: Please refer to Figure 1 - Figure 5 Based on Embodiment 1, an adjustable mechanism is added. Specifically, multiple bolt holes 9 are formed on the surface of the lever 7, and the counterweight 8 is bolted to different positions of the bolt holes 9, thereby adjusting the lever arm ratio and changing the buoyancy required to trigger the addition, thus achieving precise control of the addition point. Simultaneously, the size and number of overflow troughs 5 at the bottom of the buoyancy chamber 2 can be designed to be replaceable. By replacing the overflow trough baffles of different specifications, the speed at which water flows into the buoyancy chamber can be adjusted, thereby fine-tuning the device's response sensitivity to water level changes.

[0020] During operation, the operator can first set the basic liquid level by adjusting the position of the counterweight 8 on the lever 7 according to process requirements. Then, by observing the actual dosing, if the device's response speed needs adjustment, the overflow tank baffle with different opening sizes can be replaced. For example, to speed up the response, a baffle with a larger opening can be used; to slow down the response, a baffle with a smaller opening can be used. This allows the device to adapt to different operating conditions and water quality changes through simple mechanical adjustments.

[0021] The working principle described above can be summarized as follows: This device utilizes the buoyancy generated by changes in the liquid level within the reactor body as the driving source. Through a lever amplification principle, it controls the opening and closing of the discharge port, achieving automatic linkage between the seed crystal dosage and the reactor liquid level. Its entirely mechanical structure requires no external power, ensures reliable operation, and allows for multi-dimensional adjustment via mechanical means.
