Description

Technical Field

[0001] This utility model relates to the field of scale-water separation boxes, and more specifically, to a scale-water separation box. Background Technology

[0002] In industrial and municipal circulating water or wastewater treatment processes, excessively high levels of hardness components (such as calcium and magnesium ions) in the water can easily lead to scaling problems, causing pipe blockages, reduced equipment efficiency, and even affecting the normal operation of the entire water treatment system. Traditional descaling methods mainly include chemical softening, ion exchange, and membrane separation.

[0003] In recent years, electro-adsorption technology has been increasingly applied in the field of descaling due to its high efficiency and environmental friendliness. This technology adsorbs hardness ions in water using electrodes, causing the adsorbed scale to detach. However, the problem of efficiently collecting and transporting the scale formed after adsorption has not yet been effectively solved. Traditional scale collection methods mostly rely on manual or simple mechanical operations, which are inefficient and prone to causing secondary pollution.

[0004] Therefore, there is an urgent need for a scale-water separation box that can efficiently collect, filter, and transport scale, in order to solve the problems of low descaling efficiency, high risk of secondary pollution, and poor equipment adaptability in existing technologies. Utility Model Content

[0005] This utility model provides a scale-water separation box to at least solve the problem of low scale-water separation efficiency in related technologies.

[0006] According to one embodiment of the present invention, a scale-water separation box is provided, comprising: a box body, wherein a scale-inhibiting and water-permeable component is provided inside the box body, the scale-inhibiting and water-permeable component cooperates with the box body to form a sedimentation zone and a drainage zone, the scale-inhibiting and water-permeable component includes a support plate and a water-permeable cloth fixed on the support plate, wherein the pore size of the water-permeable cloth is smaller than a preset value.

[0007] In one exemplary embodiment, the support plate is made of a non-metallic material with a mesh count greater than 80.

[0009] In one exemplary embodiment, the drainage area is provided with a water outlet, and a filter element is provided at the water outlet.

[0010] In one exemplary embodiment, the bottom level of the sedimentation zone is higher than the bottom level of the drainage zone.

The drive shafts are arranged sequentially along the movement direction of the housing. The drive motor drives the drive shafts to rotate, so that the drive shafts provide a force for movement to the housing, thereby driving the housing to move.

[0013] In one exemplary embodiment, the driving assembly includes a drive motor and a guide wheel. The guide wheel is connected to the drive motor via a transmission assembly, and the drive motor drives the guide wheel to rotate via the transmission assembly.

[0014] In one exemplary embodiment, the housing is lined with a plastic coating having a thickness of 1-4 mm.

[0015] This invention improves filtration efficiency by using a permeable cloth to perform secondary filtration of scale. Simultaneously, it reduces the environmental impact of circulating water or wastewater discharged from the tank. Therefore, it solves the problem of low scale-water separation efficiency and achieves the effect of increasing efficiency while reducing labor intensity. Attached Figure Description

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0020] Furthermore, in this application, directional terms such as "upper," "lower," "left," and "right" may be defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and may change accordingly depending on the orientation of the components in the accompanying drawings.

[0021] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the term "coupled" can refer to an electrical connection that enables signal transmission.

[0022] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0023] This embodiment provides a scale-water separation box, such as Figure 1-2 As shown, the device includes a housing 1, which is typically located below the descaling equipment and serves to collect scale from the equipment. When circulating water or wastewater needs treatment, power is supplied to the electro-adsorption descaling device, creating an electric field within the reaction chamber. Under the influence of this electric field, anions and cations (e.g., calcium ions, magnesium ions) in the circulating water or wastewater are adsorbed onto the electro-adsorption descaling device, forming solid scale (typically composed of calcium carbonate or other solids). When the adsorption time reaches a certain threshold or the amount of scale on the electro-adsorption descaling device reaches a certain level, some components of the device (e.g., a vibrating motor) activate, causing the scale to detach from the device and fall into a scale-water separation tank.

[0024] The enclosure 1 adopts an integrated box-shaped structure, consisting of a bottom plate, front and rear end plates, left and right side plates, and a removable top cover. Notably, the side plates are continuously welded to the bottom plate and additionally sealed with adhesive to ensure no leakage under full load. All welds undergo a three-step process of pickling, passivation, and electropolishing. The exterior of enclosure 1 is coated with a double layer of epoxy zinc primer and an aliphatic polyurethane topcoat, with a total coating thickness ≥260μm. Enclosure 1 is made of rigid materials to extend its service life. These rigid materials can be metals such as stainless steel, iron, tungsten steel, and aluminum alloys, or new materials such as carbon fiber and graphene, or even thickened plastics, as long as they possess sufficient strength and can withstand a certain amount of impact; no specific limitations are imposed here. For example, the tank body 1 is made of 2mm to 4mm thick 304 stainless steel plate, which is integrally bent and welded. This is because circulating water often contains chloride ions (Cl⁻), which are highly corrosive to ordinary carbon steel. 304 stainless steel is rich in chromium (Cr) and nickel (Ni), which can form a dense and stable chromium-rich oxide film (passivation film) on the surface, effectively resisting pitting and crevice corrosion of chloride ions. It is especially suitable for treating neutral or weakly alkaline circulating water environments. In particular, under harsh conditions such as extremely high chloride ion concentration or large fluctuations in water pH, it can be upgraded to 316L stainless steel (which has molybdenum added to its composition) with better corrosion resistance to balance chloride ion corrosion resistance and high strength requirements. When the scale has strong acid and alkali corrosiveness, a 1-4mm plastic coating can be used as an inner lining. For lightweight scenarios (such as rooftop units), the PP injection-molded shell can be reinforced, and a stainless steel keel can be added internally to enhance impact resistance. However, regardless of the material, it must pass a 1m drop test and a 3t concentrated load test without plastic deformation.

[0025] Because the scale detaches from the electrodes carrying some scale water, this scale water gradually accumulates in the tank after falling into it. To remove this scale water and reduce the labor intensity for workers caused by the high water content of the scale, as follows: Figure 1 and Figure 2As shown, one end of the housing 1 is provided with a drain outlet 13, which can be configured as a tubular outlet; a filter element 4 and a drain valve 5 are provided at the drain outlet 13. The filter element 4 can be threaded to the end of the drain outlet 13 located inside the housing 1, or bolted, or fixed by a flange or other means; the drain valve 5 is used to control the opening and closing of the drain outlet 13; at the same time, a scale-inhibiting and water-permeable component 3 is provided inside the housing 1. The scale-inhibiting and water-permeable component 3, together with the side plate of the housing 1, forms a settling zone 11 and a drainage zone 12. The drain outlet 13 and the filter element 4 are both located at the bottom of the drainage zone 12, and the drain valve 5 is located outside the housing 1; when the electro-adsorption descaling device is working, a mixture of flaky, lumpy, or powdery scale containing a large amount of water falls into the settling zone 11 inside the housing, and due to gravity... When the denser solid scale begins to settle naturally, it forms a preliminary solid-liquid stratification. Then, as the liquid level in tank 1 rises, the relatively clear scale water on the upper layer begins to flow towards the drainage area 12 under the action of static pressure difference. During this process, the scale water first needs to pass through the scale-blocking and water-permeable component 3. This component can effectively intercept most of the suspended fine scale particles, causing them to remain in the settling area 11, thus achieving the initial filtration and separation of circulating water or wastewater. Subsequently, the filter element 4 performs secondary filtration of circulating water or wastewater to remove even smaller suspended solids, ensuring that the discharged water quality meets the reuse or discharge standards, and strictly preventing any solid particles from clogging the drain valve and subsequent pipelines. This achieves the secondary filtration of circulating water or wastewater, while also preventing impurities in the circulating water or wastewater from clogging the drain outlet.

[0026] It is easy to understand that, in order to effectively discharge circulating water or wastewater, a support (such as a U-shaped steel) can be installed at the bottom of the settling zone 11 so that the bottom level of the settling zone 11 is higher than the bottom level of the drainage zone 12, so that the circulating water or wastewater can flow into the drainage zone 12. The height difference is in the range of 5-15cm, preferably 8cm. This is because if the height difference is less than 5cm, the static pressure head driving the water flow will be insufficient, which may lead to slow drainage, especially when the surface of the scale-inhibiting permeable part is partially blocked, which is more likely to cause blockage. If it is greater than 15cm, it will unnecessarily increase the total height and volume of the tank, increasing manufacturing costs and equipment space occupation. When draining, the drain valve 5 is opened, and the circulating water or wastewater in the drainage zone 12 enters the drain outlet 13 after being filtered by the filter element 4 and is discharged from the drain outlet 13.

[0027] To improve the filtration efficiency of scale-inhibiting and water-permeable component 3, such as Figure 3As shown, the scale-inhibiting and permeable component 3 includes a support plate 31 and a permeable cloth 32 fixed on the support plate 31. The support plate 31 can be fixed by opening an installation groove on the side wall of the tank 1, or by bolting or welding a mounting bracket to the side wall of the tank 1. The support plate 31 is installed through the installation groove or mounting bracket. The support plate 31 is made of rigid material to provide support and adapt to the impact force of circulating water or wastewater. For example, it can be a perforated plate (porosity must be greater than 50% to reduce water flow resistance), a metal mesh, or a welded steel mesh. Perforated plates are a better choice because their flat surface makes it easy to lay and fix the permeable cloth. The material of the permeable cloth 32 can be 80-150 mesh (i.e. 0.106mm-0.180mm) polyester filter cloth, and its pore size cannot be greater than 0.18mm (preset value). Otherwise, some scale will pass through the scale-blocking permeable part 3. Moreover, most of the scale particles that are worth recovering have a diameter much larger than 0.18mm. Choosing this pore size can effectively intercept the vast majority of scale while maintaining low water flow resistance and avoiding excessive clogging.

[0028] To facilitate moving the enclosure, a drive assembly can be installed at the bottom of enclosure 1, such as... Figure 1 and Figure 2 As shown, the drive assembly includes guide wheels 25 located at the bottom of the housing, a drive motor 23, and transmission components such as a chain (not shown) and drive gears (not shown). There are two pairs of guide wheels 25, each pair mounted on both ends of a mounting shaft. The drive gears are mounted on the mounting shaft and driven by the chain. The drive motor 23 drives at least one pair of guide wheels 25 to rotate, and then drives the other pair of guide wheels 25 to rotate via the chain, thus realizing the movement of the housing 1. The drive motor 23 is controlled by an external controller; that is, the drive motor 23 drives the guide wheels 25 to rotate only after receiving a drive command from the external controller. The drive command can be transmitted via a wireless network or bus, etc., which is not limited here. To accommodate as much scale as possible, the guide wheels 25 can be made of metal and equipped with guide rails 24, along which the guide wheels 25 slide; or as... Figure 3As shown, the drive assembly is configured as a transmission motor and a transmission shaft 21. Multiple transmission shafts 21 are provided, their length direction perpendicular to the movement direction of the housing 1, and the transmission shafts 21 are arranged sequentially along the movement direction of the housing 1. Specifically, a transmission motor can be provided at one end of each transmission shaft 21, or a transmission motor can be provided at one end of one or more transmission shafts 21, and transmission can be achieved through a chain or other transmission assembly. The transmission motor drives the transmission shaft 21 to rotate. Since the housing 1 presses against the transmission shaft 21, there is friction between the bottom of the housing 1 and the transmission shaft 21. When the transmission shaft 21 rotates, under the action of friction, the transmission shaft 21 provides a force for movement to the housing 1, thereby driving the housing 1 to move. The drive assembly can also be in other forms; no limitation is made here. It is easy to understand that regardless of how the drive assembly is configured, its drive motor 23 / transmission motor and the aforementioned vibration motor are all uniformly controlled by an external controller to achieve precise control of the electro-adsorption descaling and vibration descaling processes.

[0029] Example 2

[0030] The difference from Example 1 is that, as Figure 3 As shown, the scale-inhibiting and water-permeable component 3 includes a scale-inhibiting plate 33 and a water-permeable cloth 32. The scale-inhibiting plate 33 has a scale-water separation hole 34 and a second scale-inhibiting hole 35. The scale-water separation hole 34 is located in the upper half of the scale-inhibiting plate 33, and the second scale-inhibiting hole 35 is located in the lower half of the scale-inhibiting plate 33. The diameter of the second scale-inhibiting hole 35 is smaller than the diameter of the scale-water separation hole 34.

[0031] When circulating water or wastewater flows through the scale inhibitor plate 33, the resistance to water flow is much greater than that of the scale-water separation holes in the upper part due to the smaller diameter of the second scale inhibitor hole 35. This causes most of the water flow to tend to pass through the upper part, while the lower layer of water flow slows down and increases in pressure due to the obstruction of the small diameter holes. At this time, some of the water flow is forced to turn upward, causing the lower layer of circulating water or wastewater to form a backflow and collide and shear with the upper layer of circulating water or wastewater, forming a local backflow and vortex zone in front of the scale inhibitor plate 33. This turbulent zone is like a "miniature reactor". The fine scale particles that were originally carried by the water flow and stably suspended become chaotic in this area, and the probability of collision with each other is greatly increased. This collision helps to break the particles. The hydration film on the surface promotes the aggregation of particles into larger particles (i.e., hydraulic flocculation). Once larger particles are formed, their settling velocity increases dramatically (the settling velocity is proportional to the square of the particle diameter). These larger particles are more likely to overcome the influence of the upflow, thus causing the particles that were originally carried to the upper layer to settle to the lower layer of the water flow. Even if some particles do not settle completely, when they reach the scale inhibitor plate with the water flow, they will be intercepted and filtered by the smaller second scale inhibitor pores 35 due to their increased size, thereby achieving full filtration of scale water and improving scale water separation efficiency.
