Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] The purification equipment provided by this utility model will be described in detail below with reference to the embodiments.

[0027] Please see Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a first partial schematic diagram of the first embodiment of the purification device of this application; Figure 2 This is a first partial cross-sectional schematic diagram of the purification device of the first embodiment of this application; Figure 3 yes Figure 2The structural schematic diagram of A is shown. The application provides a purification device. The purification device 10 comprises an outer cylinder 11, an inner cylinder 12, an adsorption part 13, a connecting part 14 and a connecting cover 15. The inner cylinder 12 is arranged in the outer cylinder 11. The inner cylinder 12 can store a process medium (not shown in the figure). The process medium can be but is not limited to helium, etc. The adsorption part 13 is arranged in the inner cylinder 12. The adsorption part 13 can be provided with an active substance (not shown in the figure). The active substance can be but is not limited to activated carbon, etc. The connecting part 14 connects the inner cylinder 12 to fix the inner cylinder 12. The connecting part 14 can be detachably connected or fixedly connected to the inner cylinder 12. In this embodiment, the connecting part 14 is welded to the inner cylinder 12.

[0028] The connecting part 14 comprises a first end 14a and a second end 14b arranged oppositely. The first end 14a is connected to the adsorption part 13. The first end 14a and the adsorption part 13 can be detachably connected or fixedly connected. In this embodiment, the first end 14a and the adsorption part 13 are welded. The first end 14a and the adsorption part 13 are connected in communication. The second end 14b extends out of the outer cylinder 11. The second end 14b is provided with an active substance filling port 14c. The active substance filling port 14c can be used as an inlet for filling the active substance. The connecting cover 15 can be detachably connected to the second end 14b. The detachable connection can be but is not limited to clamping, plug-in and screwing, etc. When the connecting cover 15 is connected to the second end 14b, the connecting cover 15 can be arranged on the active substance filling port 14c. When the connecting cover 15 is disconnected from the second end 14b, the connecting cover 15 can open the active substance filling port 14c.

[0029] Through the connection and communication between the connecting part 14 and the adsorption part 13, the active substance filling port 14c is located outside the outer cylinder 11, which can be directly operated when filling the active substance, without the need to use a special wrench (not shown in the figure) and a special filling funnel (not shown in the figure), so as to facilitate the filling of the active substance and improve the use experience. In addition, the connecting part 14 is connected to the inner cylinder 12 to fix the inner cylinder 12, etc. At the same time, the active substance filling port 14c is located outside the outer cylinder 11, which can be directly connected to hot nitrogen gas. The hot nitrogen gas can directly blow the active substance to realize the rapid activation of the active substance, etc.

[0030] The connecting portion 14 can have at least two configurations. The first configuration of the connecting portion 14 is as follows. The connecting portion 14 comprises a first connecting portion 141 and a second connecting portion 142. The second connecting portion 142 is connected and communicated between the first connecting portion 141 and the adsorption portion 13. The second connecting portion 142 is detachably or fixedly connected to the first connecting portion 141, or the second connecting portion 142 is detachably or fixedly connected to the adsorption portion 13. In the present embodiment, the second connecting portion 142 is welded between the first connecting portion 141 and the adsorption portion 13. When the second connecting portion 142 is connected between the first connecting portion 141 and the adsorption portion 13, the second connecting portion 142 is respectively communicated with the first connecting portion 141 and the adsorption portion 13.

[0031] The first connecting portion 141 is connected to the inner cylinder 12. The first connecting portion 141 penetrates the inner cylinder 12, and the outer periphery of the first connecting portion 141 is connected to the inner cylinder 12. The first connecting portion 141 is used to fix the inner cylinder 12. The inner cylinder 12 can be welded to the outer periphery of the first connecting portion 141. The first connecting portion 141 comprises a second end 14b. The second connecting portion 142 is located in the inner cylinder 12.

[0032] The first connecting portion 141 not only allows the active substance filling port 14c to be arranged outside the outer cylinder 11, so that the first connecting portion 141, the second connecting portion 142 and the adsorption portion 13 are communicated, thereby facilitating the replacement of the active substance and the like; but also the first connecting portion 141 can serve as a neck pipe of the inner cylinder 12, and can also fix the inner cylinder 12.

[0033] Specifically, along the connecting portion 14 towards the adsorption portion 13, the longitudinal section of the second connecting portion 142 is isosceles trapezoidal. The longitudinal section of the second connecting portion 142 gradually increases from the connecting portion 14 towards the adsorption portion 13, which facilitates the filling of the active substance and improves the user experience. Further, the second connecting portion 142 as a whole can be but not limited to a circular truncated cone.

[0034] Please refer to Figure 4 , Figure 4 is a partial cross-sectional view of the second embodiment of the purification device. In combination with Figures 1 to 3The second arrangement of the connecting part 14 is as follows. The connecting part 14 comprises a third connecting part 143 and a fourth connecting part 144. The fourth connecting part 144 is connected and communicated between the third connecting part 143 and the adsorption part 13. The fourth connecting part 144 is detachably or fixedly connected to the third connecting part 143 or the adsorption part 13. In this embodiment, the fourth connecting part 144 is welded between the third connecting part 143 and the adsorption part 13. When the fourth connecting part 144 is connected between the third connecting part 143 and the adsorption part 13, the fourth connecting part 144 is communicated with the third connecting part 143 and the adsorption part 13.

[0035] The third connecting part 143 is connected and communicated with the top end of the inner cylinder 12. The third connecting part 143 is connected with the top end of the inner cylinder 12, and the third connecting part 143 is used to fix the inner cylinder 12. The top end of the inner cylinder 12 can be welded to one end of the third connecting part 143 away from the second end 14b. When the lower end of the third connecting part 143 is connected with the top end of the inner cylinder 12, the third connecting part 143 and the inner cylinder 12 are communicated. The end of the fourth connecting part 144 away from the adsorption part 13 is connected with the top end of the inner cylinder 12. The fourth connecting part 144 is detachably or fixedly connected to the top end of the inner cylinder 12. In this embodiment, the fourth connecting part 144 is welded to the top end of the inner cylinder 12. The purification device 10 comprises a neck tube (not shown in the figure). The neck tube is the third connecting part 143 described above.

[0036] The neck tube not only enables the active material filling port 14c to be arranged outside the outer cylinder 11, so that the neck tube, the fourth connecting part 144 and the adsorption part 13 are communicated, thereby facilitating the replacement of the active material and the like, but also is a structure of the purification device 10 itself, which can reduce the use of parts and save costs, and can also play the role of the inner cylinder 12. The longitudinal section of the fourth connecting part 144 can be, but is not limited to, a square and the like.

[0037] The connecting part 14 can also have other arrangements, which are not limited here.

[0038] In some embodiments, the purification device 10 comprises a heating element 16. The heating element 16 is connected to the connecting cover 15. The heating element 16 is detachably or fixedly connected to the connecting cover 15. During the connection of the heating element 16 to the connecting cover 15, the heating element 16 extends into the connecting part 14 and the adsorption part 13 in sequence. The heating element 16 plays a heating role and can heat the active material in the adsorption part 13.

[0039] Since the connecting cover 15 and the active material filling port 14c are located outside the outer cylinder 11, the power line of the heating element 16 can be at room temperature, and the power line does not need to meet the low-temperature resistance requirement, thereby reducing the cost and the like. The heating element 16 can be, but is not limited to, a heating rod and the like.

[0040] Specifically, the heating member 16 can be sleeved and fixedly connected to the connecting cover 15. Since the connecting cover 15 is located outside the outer cylinder 11, the heating member 16 can be directly fixed to the connecting cover 15, so that the dismounting frequency of the heating member 16 can be reduced, the damage risk of the heating member 16 can be reduced, and the cost can be saved.

[0041] In some embodiments, the purification device 10 comprises a sealing member 17. The sealing member 17 is arranged between the connecting cover 15 and the second end 14b. The sealing member 17 plays a sealing role, so that the sealing property between the connecting cover 15 and the second end 14b can be improved. Since the connecting cover 15 and the second end 14b are both located outside the outer cylinder 11, the above sealing member 17 only needs to be sealed at room temperature, and does not need to be sealed at low temperature. Therefore, the sealing member 17 can be made of a conventional material, and does not need to be made of a low-temperature-resistant material, so that the cost can be reduced, and the sealing reliability can be improved.

[0042] In a specific embodiment, a side surface of the connecting cover 15 facing the second end 14b is provided with a first connecting groove (not shown in the figure). An end surface of the second end 14b facing the connecting cover 15 is provided with a second connecting groove (not shown in the figure). The sealing member 17 can be at least partially embedded in the first connecting groove and / or the second connecting groove. The above sealing member 17 can be, but is not limited to, a sealing ring (not shown in the figure).

[0043] Since the sealing member 17 is connected between the connecting cover 15 and the second end 14b, and the second end 14b is located outside the outer cylinder 11, when the purification device 10 activates the active substance, since the sealing member 17 is far enough from the active substance, the heating member 16 generates heat when inserted into the adsorption part 13. The heating member 16 does not generate heat near the position of the second end 14b. When the temperature of the active substance rises, it is difficult to affect the sealing member 17, so that the risk of failure of the sealing member 17 caused by high-temperature burning of the sealing member 17 can be avoided.

[0044] Please refer to Figure 5 and Figure 6 , Figure 5 is a second partial cross-sectional view of the first embodiment of the purification device of the present application; Figure 6 is Figure 5 the structure of B shown in FIG. 2B. In combination with Figures 1 to 4In some embodiments, the second end 14b is provided with a fixing cover 145. The second end 14b is detachably or fixedly connected to the fixing cover 145. In the present embodiment, the fixing cover 145 is integrally formed on the outer periphery of the second end 14b. The fixing cover 145 has a transverse cross-sectional dimension greater than that of the second end 14b in a direction perpendicular to the connecting portion 14 towards the adsorption portion 13. That is, the fixing cover 145 has a size greater than that of the second end 14b. The connecting cover 15 is detachably connected to the fixing cover 145. The detachable connection can be, but is not limited to, clamping, insertion, and bolting. In the present embodiment, the connecting cover 15 is connected to the fixing cover 145 by means of a plurality of bolts.

[0045] By increasing the size of the fixing cover 145, and simultaneously detachably connecting the fixing cover 145 and the connecting cover 15, the connecting area between the fixing cover 145 and the connecting cover 15 can be increased, thereby improving the stability of the connecting cover 15. In the present embodiment, the sealing member 17 is connected between the connecting cover 15 and the fixing cover 145.

[0046] The connecting cover 15 described above can be, but is not limited to, a flange cover (not shown in the figure). The inner cylinder 12 can be, but is not limited to, a liquid nitrogen Dewar inner cylinder. The adsorption portion 13 can be, but is not limited to, an activated carbon adsorber.

[0047] In some embodiments, the purification device 10 comprises a guide assembly 18 and a float level assembly 19. The guide assembly 18 is connected to the float 191 of the float level assembly 19. The guide assembly 18 is detachably connected to the float 191. The guide assembly 18 is used to limit the movement direction of the float 191. By connecting the guide assembly 18 to the float 191, the float 191 can be limited and guided, without consuming the buoyancy of the float level assembly 19.

[0048] The float level assembly 19 comprises a float rod 192 and a float 191. The float 191 is connected to the lower end of the float rod 192. Due to the guiding effect of the guide assembly 18, the float rod 192 is not easy to bend, the float rod 192 can be thinner, and the buoyancy is greater. When the float level assembly 19 is in use, the float 191 will not fail to float up due to a little resistance.

[0049] Specifically, the guide assembly 18 comprises a guide rod 181 and a guide sleeve 182. The guide rod 181 is vertically arranged in the inner cylinder 12. The guide rod 181 is detachably or fixedly connected to the inner cylinder 12. In the present embodiment, the bottom of the guide rod 181 is welded to the bottom of the inner cylinder 12. The guide sleeve 182 is sleeved on the guide rod 181. The guide sleeve 182 is connected to the float 191. The guide sleeve 182 is detachably or fixedly connected to the float 191. In the present embodiment, the guide sleeve 182 can be welded to the outer periphery of the float 191.

[0050] Through the cooperation of the guide rod 181, the guide sleeve 182 and the floating ball 191, the floating ball 191 can be limited and guided, and the risk of bending of the floating rod 192 can be reduced. Meanwhile, the guide rod 181 of the purification equipment 10 can limit the shaking of the floating ball 191 in the front, back, left and right directions, so as to avoid the damage of the floating ball 191 and the bending of the floating rod 192 caused by the collision.

[0051] The terms "first", "second", "third" in the present application are only for descriptive purpose, and cannot be understood as indicating the number of the technical features. Therefore, the features with "first", "second", "third" can explicitly or implicitly include at least one of the features. All directional indications (such as upper, lower, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship between the components, the movement condition, etc. in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.
