Description

Technical Field

[0001] This utility model belongs to the field of water purification technology, specifically relating to a novel resin purification device. Background Technology

[0002] In the water purification system of existing small hydrogen production equipment, resin tanks and filters are often required as two separate devices, which occupy a large space in a limited area. Furthermore, the installation process is difficult, resulting in long installation times and a high risk of injury.

[0003] Traditional water purification devices often use a single filter layer or a fixed resin bed, which lacks the ability to intercept the filter medium (such as resin). This makes the pipes prone to blockage due to resin migration. In view of this, the present invention provides a novel resin purification device to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel resin purification device, comprising a tank and a partition disposed inside the tank to divide the interior of the tank into an upper cavity and a lower cavity, wherein the tank is further provided with an inlet pipe and an outlet pipe respectively connecting the lower cavity and the upper cavity;

[0005] The upper cavity is provided with a filter element, and the partition is provided with a double-screen filter assembly for connecting the upper cavity and the lower cavity. The end of the double-screen filter assembly extends into the filter element.

[0006] As a preferred embodiment of the novel resin purification device of this utility model, the tank body includes a cylindrical body and a detachable cap connected to the top of the cylindrical body.

[0007] As a preferred embodiment of the novel resin purification device of this utility model, the periphery of the tank is also provided with a transparent part that allows the interior of the upper cavity to be seen.

[0008] As a preferred embodiment of the novel resin purification device of this utility model, the transparent part is a viewing window or a tank shell made of transparent material.

[0009] As a preferred embodiment of the novel resin purification device of this utility model, the dual-screen filtration assembly includes a tube body and a screen mesh disposed at the beginning and end of the tube body.

[0010] As a preferred embodiment of the novel resin purification device of this utility model, the aperture of the screen at the end of the tube is smaller than the aperture of the screen at the beginning of the tube.

[0011] As a preferred embodiment of the novel resin purification device of this utility model, the beginning end of the tube is provided with threaded ribs, and the partition plate is provided with threaded through holes, and the beginning end of the tube is threadedly connected to the partition plate through the threaded through holes.

[0012] As a preferred embodiment of the novel resin purification device of this utility model, a screen is provided at the connection between the end of the water inlet pipe and the lower cavity to intercept resin from entering the interior of the water inlet pipe.

[0013] As a preferred embodiment of the novel resin purification device of this utility model, it further includes a support frame fitted around the periphery of the tank body. The support frame includes a frame for accommodating the tank body and frame ears connected to both sides of the frame.

[0014] As a preferred embodiment of this novel resin purification device, the surface of the bracket ear is provided with several positioning holes that can cooperate with fasteners.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model effectively reduces the overall volume of the device by integrating the resin tank and the filter together, thereby reducing the space it occupies;

[0017] 2. This utility model achieves a three-stage filtration system by using two sets of screens in the dual-screen filtration assembly and in conjunction with the filter element, thereby improving the retention rate of impurities and resins and completing the gradient purification of fluids. It is particularly effective in removing particulate pollutants such as colloids and suspended solids.

[0018] 3. By setting the second screen at the end of the water inlet pipe, this utility model can further prevent the resin located in the lower cavity from entering the water inlet pipe, thereby achieving backflow prevention. This reduces the risk of pipe blockage during the start-up and shutdown of the device to near zero and improves the stability of operation. Attached Figure Description

[0027] 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.

[0028] This utility model relates to a novel resin purification device, such as... Figures 3-4 As shown, the device includes a tank 1 and a support frame 8 for fixing the tank 1, as well as a partition 2 disposed inside the tank 1 to divide the interior of the tank 1 into an upper cavity and a lower cavity. The lower cavity is used to hold resin. The tank 1 is also provided with an inlet pipe 3 and an outlet pipe 4 that connect the lower cavity and the upper cavity, respectively. In this embodiment, the end of the inlet pipe 3 extends into the lower cavity after passing through the partition 2 from the top of the tank 1. At the same time, in order to prevent resin in the lower cavity from entering the inlet pipe 3, a screen 2 is provided at the end of the inlet pipe 3 to intercept the resin from entering the interior of the inlet pipe 3. The upper cavity is also provided with a filter element 7, and the partition 2 is provided with a double-screen filter assembly 6 for connecting the upper cavity and the lower cavity. The end of the double-screen filter assembly 6 extends into the interior of the filter element 7.

[0029] During use, water flows into the lower chamber through the inlet pipe 3. The functional groups of the ion exchange resin react with the ions in the water to remove dissolved inorganic salts such as calcium, magnesium, sodium, iron ions, heavy metals, and acid radicals, thereby softening or desalinizing the water to meet the purity requirements of the hydrogen production process. As the water is continuously forced in, the water level rises in the lower chamber. Eventually, the softened water passes through the double-screen filter assembly 6 to filter out the resin, and then is further filtered by the filter element 7 before entering the upper chamber. Finally, it is discharged from the outlet pipe 4 to complete the entire purification process.

[0030] Among them, such as Figure 4 As shown, the tank 1 includes a cylindrical body 11 and a detachable cap 12 connected to the top of the cylindrical body 11. In this embodiment, the cap 12 and the cylindrical body 11 are connected by a snap-fit ​​connection, such as a latch lock, to facilitate its removal.

[0031] Furthermore, to facilitate observation of the internal filtration status of the device and meet the needs of visual operation and maintenance, a transparent section 13 that allows visibility into the upper cavity is provided on the periphery of the tank body 1. Specifically, the transparent section 13 can be a viewing window installed on the periphery of the cylinder body 11, through which the internal filtration status can be easily viewed; of course, in addition to the viewing window, the outer shell of the tank body 1 can also be made directly from transparent material, with the transparent outer shell provided at least on the periphery of the cylinder body 11 located in the upper cavity.

[0032] like Figure 5 As shown, the dual-screen filter assembly 6 includes a tube 61 and a screen 62 disposed at the beginning and end of the tube 61. The screen 62 intercepts resin inside the lower chamber as softened water enters the upper chamber, preventing resin from entering the upper chamber or the outlet pipe 4 and causing resin consumption. To further intercept the resin, the aperture of the screen 62 at the beginning of the tube 61 is set to be larger than that of the screen 62 at the end of the tube 61, thereby forming a two-stage interception of resin between the lower and upper chambers, intercepting resin particles of different sizes respectively to prevent resin loss.

[0033] Furthermore, threaded ribs are provided around the beginning of the tube 61, and threaded through holes are provided on the partition 2. The beginning of the tube 61 is threadedly connected to the partition 2 through the threaded through holes to achieve a detachable connection between the double-screen filter assembly 6 and the partition 2. By disassembling the double-screen filter assembly 6, the resin in the lower cavity can be easily removed or filled through the threaded through holes on the surface of the partition 2, which is beneficial for later maintenance.

[0034] like Figures 1-2 , Figure 6 As shown, the support frame 8 includes a cylindrical frame 81 for accommodating the tank 1, and bracket ears 82 connected to both sides of the frame 81. The surface of the bracket ears 82 has several positioning holes that can mate with fasteners. The number and position of the positioning holes are not limited and can be determined according to actual needs. In use, the tank 1 is installed inside the frame 81, and fasteners, such as bolts, are inserted into the positioning holes. It can be fixed to a wall or other desired location using impact screws to secure the tank 1.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
