Description

Technical Field

[0001] This utility model belongs to the technical field of PEM hydrogen production system, specifically relating to a modular resin tank that can be quickly replaced. Background Technology

[0002] In a PEM hydrogen production system, the resin tank is an important component, used to remove anions and cations from the water entering the system, thereby purifying the water and ensuring the smooth operation of the system.

[0003] Currently, traditional resin tanks have a single-cavity design, with water flowing unidirectionally through the resin layer from the top (or bottom), causing the upper (or bottom) resin to be preferentially saturated with adsorption, while the middle and lower (or upper) resin layers still retain a certain adsorption capacity.

[0004] Due to its single-chamber design, it is impossible to replace the failed resin individually. The entire tank of resin must be emptied and replaced. Each replacement wastes 50%-60%. For example, with a 200L resin tank, each replacement will result in the waste of 100-120L of resin, increasing production costs.

[0005] In view of this, the present invention provides a modular resin tank that can be quickly replaced to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular resin tank that can be quickly replaced, comprising: a resin purification component for purifying water, and a first tank and a second tank connected in a sealed and detachable manner at both ends of the resin purification component for connecting pipelines, wherein water enters the resin purification component from the first tank and is purified and discharged from the second tank.

[0007] Preferably, the interior of the first tank and / or the second tank is filled with filter material.

[0008] Preferably, the resin purification component is threadedly connected to the first tank and the second tank.

[0009] Preferably, the resin purification assembly includes at least one set of resin modules that can be connected to each other in a sealed and detachable manner.

[0010] Preferably, the resin modules can be threaded together.

[0011] Preferably, the resin module includes a shell filled with resin and connected at both ends, and a partition plate fixedly connected to both ends of the shell to form an enclosure to block the resin.

[0012] Preferably, the surface of the partition has at least one through hole with a size smaller than that of the resin, so as to allow communication between the inside and outside of the housing.

[0013] Preferably, the partition at one end of the housing is a filter element that is detachably connected to the housing.

[0014] Preferably, the filter element and the housing are connected by a thread.

[0015] Preferably, the surface of the first tank and / or the second tank is further provided with a water outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a modular design for the resin tank, allowing for individual replacement of failed resin modules during resin replacement, thereby effectively saving production costs. Furthermore, the threaded connection between modules facilitates disassembly, improving resin replacement efficiency and reducing system downtime.

[0018] This invention connects a detachable filter element to one end of the resin module, allowing the inside of the resin module housing to be easily opened. This facilitates the replacement of only the resin filling inside, enabling secondary filling and reducing usage costs. Attached Figure Description

[0026] 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.

[0027] Example 1:

[0028] This utility model relates to a modular resin tank that can be quickly replaced, such as... Figures 1-3 As shown, it includes a resin purification assembly for purifying water, and a first tank 2 and a second tank 3 connected at both ends of the resin purification assembly in a sealed and detachable manner.

[0029] The first tank 2 and the second tank 3 are hollow hemispherical structures. The hollow interior of these hemispherical structures can be filled with filter material, such as PP cotton, to filter the incoming water and remove impurities. A pipe connector 5 is axially connected to the surface of each of the first tank 2 and the second tank 3 for connecting to the water pipes of the PEM hydrogen production system. In this embodiment, the pipe connector 5 is a threaded joint, connecting an inlet pipe 6 and an outlet pipe 7.

[0030] like Figure 3 As shown, the resin purification assembly includes at least one set of resin modules 1 that can be connected to each other in a sealed and detachable manner. Specifically, the resin module 1 includes a cylindrical shell 11 with both ends axially connected. A partition 12 is fixedly connected to both ends of the shell 11 to form an enclosure therewith. The internal cavity enclosed by the partition 12 is filled with resin particles for purifying the incoming water. At the same time, a number of through holes smaller than the resin particles are uniformly opened on the surface of the partition 12. On the one hand, the resin particles can be confined within the shell 11, and on the other hand, the inside and outside of the shell 11 can be connected to facilitate the inflow and outflow of the incoming water in the system.

[0031] Preferred, such as Figure 4 As shown, the two ends of the housing 11 are respectively provided with external threads 13 and internal threads 14. The first tank 2 and the second tank 3, which are connected to each other, are provided with threaded structures that can cooperate with the external threads 13 and internal threads 14 to realize the threaded connection between the three for easy assembly and disassembly.

[0032] Preferably, the thread specifications of the external thread 13 and the internal thread 14 can be unified, that is, the internal and external threads can also be threaded together, so that the resin modules 1 can also be threaded together to form a multi-layer purification of the incoming water, thereby improving the purification effect.

[0033] It should be noted that for the threaded connections between the above components, a sealing ring or PTFE tape should be installed at the connection point to form an effective seal.

[0034] In another preferred embodiment, the surface of the first tank 2 and / or the second tank 3 is further provided with a water outlet 4, which can be sealed by a cap threadedly connected to it, similar to the common connection method between the mouth and cap of a mineral water bottle. This allows for convenient drainage of water from inside the tank before resin replacement.

[0035] Example 2:

[0036] Figures 4-5 The second embodiment of the present invention is shown, which differs from the first embodiment above in that: in this embodiment, the partition 12 at one end of the housing 11 is set as a filter element 15 that is detachably connected to the housing 11, so as to open the inside of the housing 11 and replace the resin separately, thereby realizing the secondary filling of the resin in the resin module 1.

[0037] The filter element 15 is threadedly connected to the housing 11. Specifically, the filter element 15 includes an annular skeleton 151. The outer periphery of the skeleton 151 is provided with a thread structure that matches the specification of the internal thread 14 provided at the end of the housing 11. A filter screen 152 for blocking resin and achieving communication is connected inside the skeleton 151.

[0038] It should be noted that, in order to ensure that the housing 11 is connected to the filter element 15 while also satisfying the connection between it and the adjacent housing 11 or the second tank 3, the internal thread 14 should be deepened and its total width should be at least equal to the width of the perimeter of the skeleton 151 plus the width of the external thread 13.

[0039] 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.
