Description

Technical Field

[0001] This utility model relates to the field of ion exchange backwashing resin collection technology, specifically a resin collection device for ion exchanger backwashing. Background Technology

[0002] An ion exchanger is a device used for water treatment, chemical separation, and purification. It utilizes the principle of ion exchange to remove specific ions from water or solutions. It is widely used in water softening, wastewater treatment, and chemical purification. Its basic working principle involves the exchange of ions in water with a specific resin (ion exchange resin), thereby removing or replacing certain unwanted ions in the water.

[0003] The cross-shaped water distribution device at the top of the ion exchanger is mostly made of stainless steel or ABS engineering plastic. The holes on the branch pipe should be uniform (the hole diameter is Φ10-Φ12mm), while the resin diameter is about 0.4~0.7mm. During the large backwash, the broken resin is discharged from the hole of the branch pipe. However, since the hole diameter is much larger than the resin diameter, and the flow rate required for the resin to loosen during each backwash will fluctuate, it is very easy for intact resin to be discharged from the hole of the cross-shaped water distribution device, resulting in waste and reducing the cycle water production.

[0004] Therefore, we propose a resin collection device for backwashing ion exchangers to solve the problems mentioned above. Utility Model Content

An external threaded groove is provided on the outer surface of the branch pipe and on the side close to the cross-shaped water distributor. An installation component is threadedly connected to the outer side of the external threaded groove. A connecting component is installed at the lower end of the installation component and on the outer surface of the branch pipe. A collection component is installed at the lower end of the connecting component and at the bottom end of the branch pipe.

A groove is provided on the outer surface of the connecting pipe, and a threaded hole B is provided at the bottom end of the groove. The threaded hole B communicates with the interior of the insertion hole. An insert is installed on one side of the limiting ring B, and one end of the insert has a threaded hole A through it.

[0025] The connecting component 4 includes a nylon filter screen A42, which is cylindrical. Limiting rings A41 and B43 are respectively installed at both ends of the nylon filter screen A42. After long-term use of the device, when the sealing ring 64 ages and is not replaced in time, the nylon filter screen A42 is used to block the resin.

[0026] In this embodiment: the mounting components 5 and 6 are installed on the outer surface of the branch pipe 2. During the large backwashing process, the nylon filter screens A42 and B63 will block and collect the broken resin. The structure composed of the connecting component 4, mounting components 5 and 6 can be processed and manufactured according to the set water volume and pipe diameter data or the original water distribution device size. The nylon filter screens A42 and B63 are made of nylon material. Nylon has good toughness and corrosion resistance and can withstand repeated impacts from water flow in both inlet and outlet directions without damage, so as to maintain the resin collection effect of the structure.

[0027] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The mounting component 5 includes a connecting pipe 51 and an internally threaded pipe 52 that penetrates and is installed inside one end of the connecting pipe 51.

At this time, the bottom end of the limiting ring A41 is on one side of the tail end of the branch pipe 2. The external threaded connector 62 is sleeved on one end of the branch pipe 2 until the external threaded connector 62 is inserted into the bottom ring groove 46. The external threaded connector 62 is rotated to make it rotate inside the bottom ring groove 46 with the internal threaded groove 47 until one end of the branch pipe 2 squeezes the sealing ring 64, completing the installation of 6. Conversely, when the external connector 61 and the connecting pipe 51 are rotated in the opposite direction, the mounting components 5 and 6 can be disassembled for replacement or maintenance, which is convenient for arrangement.
