Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, and particularly relates to a discharging structure of an adsorber. Background Art

[0002] In the design of existing adsorbers, in order to replace the packing bed layer in a pressure vessel with packing, a special discharging port is usually provided at the lower part of the bed layer. However, the design of these discharging ports often has the following deficiencies:

[0003] 1. No discharging baffle design: Some discharging ports do not have discharging baffles, which results in that during the discharging process, some packing will stay in the discharging pipe and cannot play the adsorption role, thus wasting the adsorbent. At the same time, since the packing directly contacts the blind plate of the discharging port, when opening the blind plate flange cover during daily maintenance, it may cause the leakage of the adsorbent and it is not easy to replace the sealing gasket of the discharging port.

[0004] 2. Defects in the design of conventional discharging baffles: Although some other discharging ports are provided with conventional discharging baffles, the gap (usually 1.5 - 2 mm) reserved between the baffle and the stop block, although facilitating loading and unloading, also causes new problems. For example, during transportation, the discharging baffle is prone to rotate due to vibration, resulting in poor sealing of the packing and the packing is likely to leak from the discharging baffle into the discharging pipe. More seriously, the discharging baffle may rotate to the gap where it cooperates with the stop block, causing the baffle to fall off and losing its due function.

[0005] In summary, there are many deficiencies in the design of the discharging ports in the prior art, and there is an urgent need for a discharging structure that is more stable, has better sealing performance and is convenient for installation and maintenance to solve these problems. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a discharging structure of an adsorber, aiming to solve the problem that the discharging baffle in the prior art is prone to rotate due to vibration, resulting in poor sealing of the packing.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] A discharging structure of an adsorber includes: a discharging pipe arranged on a container, a retaining ring, a discharging baffle and a stop block are sequentially arranged inside the discharging pipe in a direction away from the container, the retaining ring, the discharging baffle and the stop block are all located on the side of the discharging pipe close to the container, the retaining ring and the stop block are fixedly arranged on the inner wall of the discharging baffle, the discharging baffle is detachably arranged between the retaining ring and the stop block, and a locking mechanism is arranged on the stop block, and the locking mechanism is used to lock the discharging baffle.

[0009] Furthermore, the number of the stop blocks is more than two, and a through groove for the stop block to pass through is formed by the inward depression of the circumferential side wall of the discharging baffle.

[0010] Furthermore, the locking mechanism includes a threaded through-hole formed in the stopper, and a fastening bolt threadedly connected to the stopper through the threaded through-hole.

[0011] Furthermore, the locking mechanism includes a through-hole formed in the stopper, a clamping rod slidably disposed on the stopper through the through-hole, a jack formed on the side of the discharge baffle close to the stopper corresponding to the clamping rod, and a magnet disposed in the jack for attracting the clamping rod.

[0012] Furthermore, the gap between the discharge baffle and the stopper is 10 - 20 mm.

[0013] Furthermore, a shallow groove extending outward is formed on the side wall of the discharge baffle close to the retaining ring, so as to maintain pressure balance between the discharge pipe and the container cylinder.

[0014] Furthermore, a discharge port flange is fixedly provided at one end of the discharge pipe far from the container, the discharge pipe communicates with the outside through the discharge port flange, and a flange cover for closing the discharge port is detachably provided on the discharge port flange.

[0015] Furthermore, a gasket is provided between the discharge port flange and the flange cover.

[0021] Typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not intended to limit the present utility model.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0023] In order to further illustrate the principle and structure of the present utility model, the preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

[0024] As Figure 1-2 shown, the embodiment of the present utility model provides a discharging structure of an adsorber, including: a retaining ring 11, a discharging baffle 12, and a retaining block 13 that are sequentially arranged in the discharging pipe 1 of the container in a direction away from the container. The retaining ring 11 and the retaining block 13 are fixedly arranged on the inner wall of the discharging pipe 1, and the discharging baffle 12 is detachably arranged between the retaining ring 11 and the retaining block 13. A locking mechanism is arranged on the retaining block 13, and the locking mechanism can lock the discharging baffle 12.

[0025] Specifically, the above-mentioned retaining ring 11, discharging baffle 12, and retaining block 13 are all located on the side of the discharging pipe 1 close to the container. As shown in the figure, the discharging baffle 12 is close to the leftmost end of the discharging pipe 1. Such a design can prevent the packing from entering the discharging pipe 1 and avoid the waste of the adsorbing parts.

[0026] Furthermore, the number of the above-mentioned retaining blocks 13 is more than two. A plurality of baffles can be distributed around the discharging baffle 12 to form a more uniform support for the discharging baffle 12, thereby enhancing the stability of the discharging baffle 12. And a plurality of retaining blocks 13 can disperse the force, reduce the load of a single retaining block 13, and contribute to improving the reliability of the entire discharging port.

[0027] Furthermore, in order to detachably install the discharging baffle 12 between the retaining ring 11 and the retaining block 13, a through groove 122 that is recessed inward is designed on the circumferential side wall of the discharging baffle 12. The through groove 122 is customized for the retaining block 13 to facilitate the smooth passing of the retaining block 13. During installation, as Figure 1In the shown direction, the operator first starts from the right side, smoothly pushes the discharge baffle 12 to the left, and rotates it appropriately to ensure that the through groove 122 precisely aligns with the stop block 13. Once the through groove 122 is accurately aligned with the stop block 13, continue to push the discharge baffle 12 to smoothly embed the stop block 13 into the through groove 122. Subsequently, continue to move the discharge baffle 12 until it is firmly placed between the retaining ring 11 and the stop block 13. At this time, rotate the discharge baffle 12 to stagger the through groove 122 and the stop block 13 to ensure the stable installation of the discharge baffle 12. The disassembly process is the opposite. By rotating the discharge baffle 12 to realign the through groove 122 with the stop block 13, and then smoothly pulling out the discharge baffle 12 to the right, the quick and convenient disassembly operation can be completed.

[0028] Furthermore, as an embodiment of the locking mechanism, the locking mechanism includes a threaded through hole opened on the stop block 13, a fastening bolt 131 threadedly connected to the stop block 13 through the threaded through hole. The number of bolts and threaded holes corresponds to the number of stop blocks 13. After installing the discharge baffle 12, rotate the fastening bolt 131 to make the bolts on multiple stop blocks 13 press against the discharge baffle 12, thereby completing the locking of the discharge baffle 12. After the discharge baffle 12 of this embodiment is pressed tightly, it is closely attached to the retaining ring 11, fixing the discharge baffle 12 axially. The way of the bolt pressing also increases the friction force acting on the discharge baffle 12, preventing the circumferential rotation of the discharge baffle 12 and fixing the discharge baffle 12 circumferentially. By fixing the discharge baffle 12 axially and circumferentially, it can prevent the discharge baffle 12 from rotating during transportation or the operation of the adsorber, avoiding the leakage of the packing.

[0029] In this embodiment, the gap between the discharge baffle 12 and the stop block 13 can be larger, which is convenient for the installation and welding of the stop block 13. The gap between the discharge plate stop block 13 and the discharge baffle 12 can be reserved 10 - 20 mm or even larger according to needs.

[0030] Furthermore, as another embodiment of the locking mechanism, the locking mechanism includes a through hole (not shown in the figure) opened on the stop block 13, a clamping rod (not shown in the figure) slidably arranged on the stop block 13 through the through hole, a jack (not shown in the figure) corresponding to the clamping rod on the side of the discharge baffle 12 close to the stop block 13, and a magnet arranged in the jack to generate an adsorption effect with the clamping rod. After the operator places the discharge baffle 12 between the retaining ring 11 and the stop block 13, rotate the discharge baffle 12 to align the clamping rod with the jack. Under the adsorption effect of the magnet, the clamping rod enters the jack to complete the circumferential locking of the discharge baffle 12. If the gap between the discharge baffle 12 and the stop block 13 is very small, the axial locking of the discharge baffle 12 can also be completed simultaneously. The specific size of this very small gap can be simply obtained by those skilled in the art through experiments and will not be elaborated here.

[0031] Furthermore, a shallow groove 121 extending outward is formed on the side wall of the discharge baffle 12 close to the retaining ring 11, so as to keep the pressure balance between the discharge pipe 1 and the container cylinder.

[0032] Furthermore, a discharge port flange 14 is fixedly arranged at one end of the discharge pipe 1 away from the container, and the discharge pipe 1 is communicated with the outside through the discharge port flange 14. A flange cover 141 for closing the discharge port is detachably arranged on the discharge port flange 14, and the discharge port flange 14 and the flange cover 141 are fixed by bolts.

[0033] Furthermore, a gasket 142 is arranged between the discharge port flange 14 and the flange cover 141, and its main function is to increase the sealing performance at the connection. Through the pre-tightening force of the bolts, sufficient pressure is generated between the gasket 142 and the flange sealing surface, and the gasket 142 undergoes plastic deformation to fill the tiny gaps existing between the flange sealing surfaces, thereby blocking the medium leakage channels and achieving the sealing effect.

[0034] Furthermore, handles are arranged on both the discharge baffle 12 and the flange cover 141 to facilitate the operation of the operator on the discharge baffle 12 and the flange cover 141.

[0035] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
