A descaling device for water supply in an ultrafiltration system

Abstract

This utility model proposes a descaling device for ultrafiltration equipment, relating to the field of ultrafiltration equipment. It includes a water supply pipe with a manifold rotatably connected to its top end. This addresses the problem that calcium and magnesium ions in the existing water supply easily form scale, adhering to the surface of the ultrafiltration membrane and the inner wall of the ultrafiltration equipment's pipes. This scale increases water flow resistance, reduces the filtration efficiency of the ultrafiltration equipment, shortens the lifespan of the ultrafiltration membrane, and increases equipment maintenance costs. Through the rotating spray structure of the manifold and nozzles, and the inclined surface design, the liquid flow generates centrifugal force and a spiral scouring effect. Compared to traditional static spraying or unidirectional rinsing, this significantly improves the coverage area and scouring intensity of the inner wall of the pipe, more efficiently destroying scale crystal nuclei and peeling off existing scale, fundamentally solving the problems of increased water flow resistance and shortened ultrafiltration membrane lifespan.

However, in actual use, calcium and magnesium ions in the water supply can easily form scale, which adheres to the surface of the ultrafiltration membrane and the inner wall of the pipes of the ultrafiltration equipment. This scale increases water flow resistance, reduces the filtration efficiency of the ultrafiltration equipment, and also shortens the service life of the ultrafiltration membrane, increasing the maintenance cost of the equipment.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a descaling device for water supply in ultrafiltration equipment to solve the problem that calcium and magnesium ions in the existing water supply easily form scale, which adheres to the surface of the ultrafiltration membrane and the inner wall of the pipes of the ultrafiltration equipment. This scale increases water flow resistance, reduces the filtration efficiency of the ultrafiltration equipment, and also shortens the service life of the ultrafiltration membrane, increasing the maintenance cost of the equipment.

This scale increases water flow resistance, reduces the filtration efficiency of the ultrafiltration equipment, shortens the service life of the ultrafiltration membrane, and increases the maintenance cost of the equipment.

[0005] The technical solution of this utility model is implemented as follows: an ultrafiltration equipment water supply and descaling device includes: a water supply pipe, the top end of which is rotatably connected to a collector seat, an inclined surface is provided on the outer circumferential surface of the collector seat, and spray holes are provided in a ring array on the inclined surface for liquid discharge.

[0006] A connecting pipe assembly is fixedly connected to the top surface of the collector, and a bearing seat is installed on the top opening of the connecting pipe assembly.

[0009] In a preferred embodiment, a bevel gear disk is fixedly connected to the top surface of the collector, and the bevel gear disk meshes with a drive gear located on the right output end of the servo motor B for transmission.

[0010] In a preferred embodiment, an inlet pipe is fixedly connected to the right side of the outer periphery of the water supply pipe. The inlet pipe is connected to the water supply pipe, and an inlet check valve is fixedly connected to the outside of the inlet pipe.

Detailed Implementation

[0024] 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.

[0025] like Figures 1-6As shown, an ultrafiltration equipment water supply descaling device includes: a water supply pipe 1, the top end of the water supply pipe 1 is rotatably connected to a collector 3013, an inclined surface is provided on the outer peripheral surface of the collector 3013, and spray holes 3014 are provided in a ring array on the inclined surface for liquid discharge.

[0026] A connecting pipe assembly 3015 is fixedly connected to the top surface of the manifold 3013 and communicates with it. A bearing seat 3016 is installed on the top opening of the connecting pipe assembly 3015. A flushing pipe 3018 is installed inside the bearing seat 3016. A guide plate assembly 3017 is fixedly connected to the bottom end of the flushing pipe 3018.

[0027] The guide plate assembly 3017 is rotatably connected to the pipe assembly 3015, and the guide plate assembly 3017 is in communication with the flushing pipe 3018. Both are used to supply liquid to the inside of the manifold 3013. A support mechanism 3 is fixedly connected to the outer circumference of the water supply pipe 1. The main body of the support mechanism 3 is an L-shaped structure, and a servo motor B301 is installed on the left end face of the support mechanism 3. A drive gear 3011 is installed on the right output shaft of the servo motor B301.

[0028] Among them, a bevel gear disk 3012 is fixedly connected to the top surface of the collector 3013. The bevel gear disk 3012 meshes with the drive gear 3011 set on the right output end of the servo motor B301. An inlet pipe 101 is fixedly connected to the right side of the outer peripheral surface of the water supply pipe 1. The inlet pipe 101 is connected to the water supply pipe 1, and an inlet check valve 1011 is fixedly connected to the outside of the inlet pipe 101. The inlet pipe 101 and the water supply pipe 1 together form the water supply structure for the ultrafiltration equipment.

[0029] Among them, a cleaning pipe 1012 is fixedly connected to the left side of the outer periphery of the water supply pipe 1. The cleaning pipe 1012 is used to overflow water from the inside of the water supply pipe 1. The cleaning pipe 1012 is located below the liquid inlet pipe 101 and is arranged opposite to the liquid inlet pipe 101. A flange 1013 is fixedly connected to the bottom end face of the water supply pipe 1. The flange 1013 is in communication with the water supply pipe 1. A support mechanism 2 is fixedly connected to the rear side of the outer periphery of the water supply pipe 1. A servo motor A201 is fixedly connected to the rear side of the support mechanism 2. An output shaft is provided at the front end of the servo motor A201. A sealing valve plate 2011 for sealing the bottom opening of the water supply pipe 1 is installed on the output shaft.

[0030] In use, firstly, external water source enters water supply pipe 1 through inlet pipe 101 and inlet check valve 1011, forming the water supply path of ultrafiltration equipment; at the same time, descaling liquid can be injected through flushing pipe 3018 and guided to the inside of manifold 3013 through guide plate assembly 3017, to store liquid for descaling operation.

[0031] After the servo motor B301 is started, its output shaft drives the drive gear 3011 to rotate. Through the meshing transmission with the bevel gear disk 3012, the collector seat 3013 rotates around the top of the water supply pipe 1. The nozzles 3014 on the outer inclined surface of the collector seat 3013 form an annular spray area as it rotates.

[0032] Under centrifugal force, the water or descaling solution in the manifold 3013 is sprayed out at high speed from the nozzle 3014 along the inclined surface, forming a spiral liquid flow that covers the inner wall of the water supply pipe 1 and the connection of the ultrafiltration equipment pipe. The direction of the spraying liquid forms an angle with the direction of the water flow, which enhances the scouring force on the inner wall, destroys the calcium and magnesium ion crystal structure, and prevents scale from adhering. At the same time, the scale that has already formed gradually falls off under the impact of the liquid flow.

[0033] When cleaning is required, the servo motor A201 drives the closed valve plate 2011 to rotate, opening the bottom opening of the water supply pipe 1. The residual liquid and detached scale are discharged through the flange 1013. The cleaning pipe 1012 is used to overflow the excess liquid in the water supply pipe 1, maintain the internal pressure stability, and prevent the liquid from flowing back to the inlet pipe 101.

[0034] The guide plate assembly 3017 is rotatably connected to the pipe assembly 3015 via the bearing seat 3016, ensuring that the collector seat 3013 can rotate independently when the flushing pipe 3018 is fixed, while ensuring the sealing of the liquid transmission path; the L-shaped structure of the support mechanism 3 provides a stable support for the servo motor B301, ensuring the stability of the gear transmission.
