Description

Technical Field

[0001] This invention relates to the field of technology, and more specifically, to an industrial soft water preparation apparatus. Background Technology

[0002] In industrial production, water is used extensively in parts processing, such as cooling water and cleaning water for crankshafts. However, hard water cannot be used for cooling or cleaning operations. This is mainly because hard water will form scale on the surface of metal parts when used for cooling or cleaning, which will affect the cooling effect on the parts and the operation and service life of the processing equipment.

[0003] Soft water preparation methods include ion exchange: using ion exchange resins to remove hardness ions from water, thereby reducing the ion concentration in the water. This method is suitable for large-scale soft water production in pharmaceutical, chemical, and other industries.

[0004] Currently, the most common method for preparing industrial soft water is ion exchange. However, ion exchange requires the use of ion exchange resins for water treatment. Ion exchange resins have limited treatment capacity, and after reaching a critical value, they need to be regenerated by adding brine to restore their working capacity. In other words, the water softening process requires a period of downtime to allow the ion exchange resins to recover, and using two sets of treatment devices would be too space-consuming. Summary of the Invention

[0005] This invention provides an industrial soft water preparation device, the purpose of which is to place two sets of ion exchange resin particles in different treatment zones, the size of which can be adjusted, and the two sets of ion exchange resin particles can be used alternately without occupying too much space.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] An industrial soft water preparation device includes a housing 1 with an opening at its upper end for receiving treated water. A partition 4 is installed inside the housing 1, dividing the interior into a first preparation zone 5 and a second preparation zone 6. Two sets of sealing grooves 15 are installed at the bottom of the housing 1 to house the partition 4. The space occupied by the first preparation zone 5 and the second preparation zone 6 differs depending on where the partition 4 is placed. Two sets of water outlets 2 are installed at the bottom of the housing 1, each located between the sealing groove 15 and the side wall of the housing 1. The partition 4, when placed in either sealing groove 15, can connect to both the first preparation zone 5 and the second preparation zone 6. A control valve 3 is installed on each water outlet 2.

[0029] Equal amounts of exchange resin particles are placed in the first preparation zone 5 and the second preparation zone 6. The first preparation zone 5 and the second preparation zone 6 are used separately. When the partition 4 is in the sealing groove 15, making the space in the first preparation zone 5 too large, the exchange resin particles in the first preparation zone 5 are used for soft water preparation. The space in the second preparation zone 6, which has a smaller space, is used for the reduction and restoration of the exchange resin particles. After working for a period of time, they are used alternately.

[0030] A transverse moving assembly is installed on the partition 4 to allow the partition 4 to be switched and placed within the housing 1. The transverse moving assembly includes a screw 10 that penetrates the housing 1. Threaded sleeves 11 are respectively installed at both ends of the partition 4. Two sets of screws 10 pass through and are threadedly connected to the threaded sleeves 11. One end of the screw 10 is mounted on a base 12, and another end of the screw 10 is connected to a drive motor 13. The drive motor 13 is mounted on another base 12. The base 12 is connected to the housing 1 via a vertically arranged electric cylinder 14. During the adjustment process, the electric cylinder 14 is first used to lift the two sets of screws 10 and the partition 4 supported by the screws 10 and threaded sleeves 11, removing the bottom of the partition 4 from the sealing groove 15. After removal, it is no longer engaged with the sealing groove 15. Using two sets of synchronous drive motors 13, which rotate in the same direction, the partition 4 is moved horizontally under the rotation of the screws 10. The horizontal movement distance of the partition 4 is determined according to the pre-set motor speed and rotation time, moving the partition 4 above the other sealing groove 15. Then, with the retraction of the electric cylinder 14, the lower end of the partition 4 is engaged into the other sealing groove 15, completing the spatial adjustment of the first preparation area 5 and the second preparation area 6. A U-shaped sealing rubber 16 is provided in the sealing groove 15 to engage the bottom of the partition 4, improving the sealing performance after engagement.

[0031] A connecting assembly is installed on the partition 4. The connecting assembly includes a connecting groove 17 on the partition 4, and a plurality of connecting holes 18 are provided in the connecting groove 17, penetrating both sides of the partition 4. An electric valve stem 19 is installed on the partition 4, and a sealing plate 20 is installed on the output end of the electric valve stem 19. The sealing plate 20 is used to seal the connecting groove 17 under the control of the electric valve stem 19. The electric valve stem 19 is a waterproof electric valve stem. Most electric valve stems 19 on the market are waterproof. The electric valve stem 19 is used to open and close the connecting groove 17 by the sealing plate 20, so as to achieve the effect of water flow in the first preparation zone 5 and the second preparation zone 6. A filter screen is provided at the connecting hole 18. The pore size of the filter screen is smaller than the particle size of the ion exchange resin particles to prevent the ion exchange resin particles from flowing through during water flow.

[0032] An adsorption assembly is installed in both the first preparation zone 5 and the second preparation zone 6. Each adsorption assembly includes an adsorption rod 23, which is cylindrical. A porous mesh is provided on the outside of the adsorption rod 23, with pores smaller than the particle size of the ion exchange resin. The two sets of adsorption rods 23 are connected back to the bottom of the first preparation zone 5 and the second preparation zone 6 via circulation pipes 24. A first suction pump 25 is installed on the circulation pipes 24. The adsorption assembly works in conjunction with the connecting assembly.

[0033] The specific workflow is as follows: Typically, the first preparation zone 5 is undergoing water softening, while the second preparation zone 6 is recovering the exchange resin particles. However, the recovery time for the exchange resin particles is relatively short. After the process is complete, the brine is removed, leaving the exchange resin particles. The first preparation zone 5 continues operating until the exchange resin particles in the first preparation zone 5 lose their working capacity. First, the electric valve stem 19 is controlled to open the sealing plate 20, connecting the first preparation zone 5 and the second preparation zone 6 through the connecting hole 18. Water flows from the first preparation zone 5 to the second preparation zone 6, during which time the exchange resin particles are not allowed to flow due to the filter screen. Then, the position of the baffle 4 needs to be adjusted to change the partition size of the first preparation zone 5 and the second preparation zone 6. During this process, raising the baffle 4 will inevitably connect the first preparation zone 5 and the second preparation zone 6, and the exchange resin particles will easily flow through the gaps, resulting in uneven distribution of exchange resin particles between the two zones. Prioritizing the flow of water through the connecting hole 18 is to keep the exchange resin particles submerged in water, facilitating adsorption by the adsorption component. Under the adsorption of the adsorption component, the water flow fluctuations generated by the baffle 4 and the connecting gaps will prevent the loss of exchange resin particles. The adsorption component draws water into the circulation pipe 24 by the first suction pump 25, and then circulates it back to the first preparation zone 5 or the second preparation zone 6 after reaching the highest point of the circulation pipe 24. However, since the pore size of the porous adsorption mesh is smaller than the particle size of the exchange resin particles, the exchange resin particles will be continuously adsorbed on the porous adsorption mesh during the operation of the first suction pump 25, thus avoiding the loss of exchange resin particles during the adjustment of the partition 4.

[0034] A sealing rubber ring 21 is installed on the sealing side of the sealing plate 20 to increase the sealing performance of the sealing plate 20.

[0035] The first preparation area 5 and the second preparation area 6 are connected to a brine storage tank 8 via a connecting pipe 7. The brine storage tank 8 is connected back to the first preparation area 5 and the second preparation area 6 via a return pipe 9. One end of the connecting pipe 7 is connected to the first preparation area 5 and the second preparation area 6, and the other end is suspended above the brine storage tank 8 and connected to the brine storage tank 8. A second suction pump 26 is installed at the suspension point of the connecting pipe 7. The brine is recyclable and ideally does not mix with the prepared soft water. The brine is transported by opening the return pipe 9 and is pumped back using the second suction pump 26 after use. The brine will absorb softening salt during use but will not consume water. Softening salt is added to the brine storage tank 8 periodically to maintain its consistency.

[0036] Filter screens are installed at both the connecting pipe 7 and the return pipe 9. The pore size of the filter screens is smaller than the particle size of the ion exchange resin particles. This prevents the second suction pump 26 from accidentally aspirating ion exchange resin particles.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
