INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a chemical reactor, and in particular to a device for loading a catalyst into a chemical reactor tube. [Prior Art] In the past, many different types of devices have been used to load catalyst into a reactor tube, for example, various sleeves, stencils, and vibrating machines have been used. The catalyst is pelletized and can have a variety of shapes and sizes. Then, once the loading of the catalyst is completed, a rod must be inserted into each tube to measure the distance from the top of the catalyst to the top of the reactor tube (reserved volume) to see if the space or reserved volume is in place. Expected within the scope of the SI. If the reserved volume is too large, additional catalyst can be loaded and the reserved volume measured again. If the reserved volume is too small, then some of the catalyst is typically removed by vacuuming the top of the tube and the reserved volume is measured again. [Invention] The present invention provides a loading sleeve for loading a catalyst into a reactor-reactor tube. The loading sleeve has an upper flange that rests on the upper plate of the reactor and extends downwardly from the flange into the reactor tube. The tube portion of the sleeve has a smaller diameter than the reactor tube, because the carrier sleeve is filled with the catalyst and then moved from the reactor tube leaves a __ space at the top of the far reactor tube or Reserve volume. ^ ~ Dry and m I example, the loading sleeve also has some form of mark. The loading sleeve has been ~. After the catalyst has settled in the reactor tube, the 96017.d〇i 1377091

By examining the markings on the portion of the reactor tube from which the loading sleeve extends, one can see if the official has been loaded to a height within a desired specification range. This eliminates the need for a separate test tool. β X. Also in a preferred embodiment of the invention, the flanges of the loading sleeve can be made sufficiently large to overlap each other. This approach helps to prevent dust and powder from collecting between the loading sleeves. [Embodiment] Fig. 1 is a cross-sectional view showing a part of a 4 drop reactor. The reactor includes an upper tubesheet 10 and a tubesheet (not shown) that is parallel to the lower portion of the upper tubesheet 10. Multiple reactions | § Tube 12 extends from the upper tube plate 1 down to the lower tube plate. The upper and lower tube sheets have an opening 14 that is aligned with the tube 12. In this figure, the loading sleeve 16 has been inserted into the reactor tube 12. Each of the loading sleeves μ includes a flange portion 18 that rests against the upper tube sheet 10 and a tubular sleeve portion 2 that extends downwardly into each of the reactor tubes 12. The flange 丨 8 defines a opening 22 which opens to the inside of the tubular sleeve portion 2 . In the yoke example, the official sleeve 20 has a constant diameter and the opening 22 has a constant diameter that is smaller than the inner diameter of the tubular sleeve 20. The size of the opening 22 depends on the size and shape of the catalyst used, which may be slightly larger than the catalyst to about three times the diameter of the catalyst to minimize the chance of bridging. Figure 2 is a top plan view showing a plurality of loading sleeves 16 inserted into a plurality of adjacent reactor tubes 12. In this figure, it can be seen that the tubular sleeve 2 and the flange 18 have a circular cross-sectional shape which is preferred for use. Of course, 960l7.doc 1377091 can also be used in other shapes. 3 is an enlarged plan view of one of the loading sleeves 16 within each of the tubes 12. The outer diameter of the downwardly projecting tubular sleeve 2 has a sufficiently small size to be easily loaded into the reactor tube 12 and the flange 18 has a size large enough to prevent the loading sleeve from being opened by the opening 4 Sliding into the reactor tube 12. Figure 5 is a schematic view showing the use of a loading sleeve to "load the catalyst into the reactor tube 12". In this figure, the catalyst 3 is shown as a sphere, but it may have a household shape. The catalyst typically has a cylindrical shape. The loading sleeve 16 is inserted into the reactor tube 12 until the flange 18 rests against the upper tube sheet weir. The catalyst 30 is then filled into the flange 18 by the opening 22. Catalyst 30 is typically filled into the flange by hand or broom, but other methods can be used. The catalyst loading sleeve is shouted and "reactor tube 12 is loaded with reactor tube 12 from the bottom up. As shown in this figure, finally, the catalyst also fills the inside of the loading sleeve 16. Once the catalyst 30 in the plurality of loading sleeves 16 is loaded to the top, the loading sleeve is then completely removed from the reactor tube 12. The loading sleeve 16 can be tapped lightly to ensure that all of the catalyst 30 is poured from the sleeve 16 and retained within its respective reactor tubes 12. Since the internal volume of the loading sleeve 16 is smaller than the volume of the portion around the reactor tube, when the loading sleeve 16 is removed, the catalyst 30 in the _ 16 will fall and fill the reactor button with a larger diameter. This is shown in Figure 7, leaving a 1 or reserved volume 32 from the top of the catalyst 30 to the top of the tubesheet 1 . The loading sleeve and the phase of the reactor tube can be selected to have an internal diameter to achieve the desired product 32 as the loading sleeve is removed from the reactor tube. Order 96017.doc 1377091 After removing the loading sleeve 16 from the reactor tube and the catalyst 30 has settled and formed the reserved volume 32, as shown in Figure 7, 'loading the loading sleeve 16 again into the reaction organ 12 ° at this time' The catalyst 3 prevents the loading sleeve from being fully inserted into the reactor tube 12. Thus, the loading sleeve 16 can only be inserted into the reserved volume 32, i.e., inserted into the point where the catalyst 30 prevents further insertion. The sleeve 16 has a tick mark 34' which is used to determine if the catalyst 3 has been loaded to the correct reserved volume. The indicia 34 is preferably on the outer surface of the sleeve 16. The tag can have multiple types. For example, as shown in FIG. 7, there may be a plurality of tick marks on the different degrees of the sleeve 16, which may indicate the distance marked above the bottom of the sleeve 16, or the bottommost mark may indicate a "〇" And the other mark indicates that it is above the height of the mark. Alternatively, a set of tags called "In spec" can be placed on the set and on top of and below these tags, called "outside specifications (〇ut〇fspec)" Mark 丨 or, apply one part of the sleeve to green or another preferred color to indicate the correct reserved grain range, and the upper and lower parts of the part may be painted with another color, such as red, to indicate that it is in the Outside the reserved volume range. Other similar indicators can also be used so that one can determine the size of the reserved volume 32 when inserting the loading sleeve back into the reactor tube, or determine if the reserved volume 32 is within a predetermined specified range. Thereby, with a single tool, a worker can either load the catalyst or check the catalyst height; the gap 32 above the catalyst is within the desired range. If the gap 32 is too large, the worker can fill in additional catalyst and check again. If the gap 32 is too small, the worker can evacuate the vacuum - and then check again and add the catalyst as needed. Since the single-work β tool has both the loading function 96017.doc and the measuring function, the worker It is not necessary to carry two separate sets of tools for performing both functions. 4 and 6 show an alternative embodiment of a loading sleeve 16 . In this embodiment, the opening 122 through the upper flange is tapered, having a smaller diameter at the top and a larger diameter at the bottom. The top surface of the flange is also concave, gradually decreasing from a higher height of one of its outer edges to a lower height adjacent one of the openings 122 to facilitate the flow of the catalyst to the center during loading. Opening. This embodiment differs from the first embodiment in that: the embodiment has a single broadband rather than having a plurality of graduations on the tube to indicate the position of the loading sleeve 116 (at such locations, the reserved volume 32 is within the desired range). If the entire belt is below the upper tubesheet and is not visible to the person, the worker measuring the reserved volume knows that the reserved volume 32 is too large and more catalyst should be added. If the worker can see that the entire belt 134 (including its bottom edge) extends above the upper tubesheet 1 则, the worker knows that the s-reservation volume 3 2 is too small and some catalyst should be removed. If only a portion of the belt 13 4 projects above the upper tubesheet 10, the worker knows that the reserved volume is within the desired range. 8-10 illustrate a second alternative embodiment of a loading sleeve 216. In this embodiment, the downwardly projecting tubular sleeve portion 22 has a constant diameter. However, the upper portion has a funnel-like taper having a larger diameter at the top and gradually decreasing to a smaller diameter. In addition, the remainder of the tubular portion 220 has a constant diameter that is slightly larger than the smaller straightness of the tapered portion. The loader 216 has a plurality of scales 2 3 4 for indicating the height of the scale above the bottom of the official sleeve 216. With this arrangement, one can obtain an actual reading of one of the reserved volume sizes 32 of 96017.doc •10·1377091, rather than just an indication of whether the reserved volume size 32 is at or beyond a predetermined range. Figures 11 and 12 show another alternate embodiment of a loading sleeve 316 made in accordance with the present invention. The loading sleeve 316 is identical to the sleeve 16 shown in Figures 1-3 except that the flange portion 318 has a larger diameter so that the flange portions 318 adjacent the loading sleeve 316 can overlap each other. The flange portion 318 has a diameter that is large enough to ensure complete overlap of the adjacent flanges so that the upper tubesheet 10 between the loading sleeves 316 is not exposed, but small enough that the flanges 3 are not The adjacent opening 322 is covered. Figure 11 shows an arrangement of such a large flange type loading sleeve 316 in which one begins to insert a sleeve 316 at one end of the reactor and then, similar to the scales on the fish, superimposes the subsequent columns of the flange 318 on the previous column. . It should be noted that the sleeve 316 is made of a slightly flexible material such as plastic so that all of the flanges 318 are adjacent to the surface of the upper tubesheet. Figure 12 shows the same large flange type loading sleeve 316 as shown in Figure 11, except that the sleeve is inserted into the sleeve in a different order, with the flange of the first column set (referred to as the odd number 歹J) being downwardly The upper panel i 〇 contacts, while the flange of the second column group (referred to as the even column) rests on the flange 3 i 8 of the first column group. Not only in the arrangement of Figure U but also in the arrangement of Figure 12, the overlap of the flanges 318 prevents dust from sinking at the location on the upper tubesheet 10 between the loading sleeves. With these arrangements, dust can be easily removed or vacuumed. Fortunately, the loading sleeve 16 is made of a hard material such as ABS plastic, rather than a soft material such as polyethylene to prevent the material from rubbing and contaminating the reactor tube 12. Although metal can be used, hard plastic is preferred. Moreover, more than 96017.doc 1377091, the flange portion _ tubular portion, the knife m is transported to operate as a single component, whereby the tubular portion 2 () will not separate and fall into the stalker tube during use. 12 in. This object can be achieved by: the flange-like portion 2G being fabricated or molded to form a single-piece; glued or welded together to form a single component; or by other known methods Preferably, a single component comprising the flange 18 and the tubular portion 20 is injection molded. If welding or gluing is used, the assembly should be inspected and tested to ensure that the flange 18 is secured to the tubular portion 20. Other secure attachments such as pin or riveting can also be used. Another desirable method uses a threaded portion 20 to be threaded into the flange head 18, wherein the two members are mated together using a plurality of turns of the tubular portion. If one of the tubular portion 20 or one of the tubular portions 20 falls into the reactor tube and cannot be removed prior to activation of the reactor, the portion melts and fuses with the catalyst, preventing airflow through the tube 12, This prevents the reactor from functioning properly and may even permanently damage the tube. This is not what we are looking for and should be avoided as much as possible. Although forming each sleeve 16 as a single component or permanently securing the flange portion 18 and the tubular portion 20 together by, for example, welding or bonding, may help alleviate the problem of the tubular portion 20 falling into the reactor tube 12, This also brings more difficulties to the storage of products. The advantage of retaining the flange portion 18 and the tubular portion 2〇 as separate components is that the product is easier to store and allows one flange portion U to be used for tubular portions 20 of various lengths and is suitable for a variety of desired reserved volumes. For example, if the flange portion 18 and the tubular portion 2〇 cannot be permanently fixed at 96017.d〇i • 12· 2 = unique barcode or other mark for each-flange portion (four) for a temporary 77 m' and registered in and out of the work area All of the flanges 18 and tubular portions 20 of each of the components are recorded so that one:: = inside the reactor tube 12. It can also be indicated in the tube TM that it is known that the above-described actual gas can be modified without departing from the scope of the invention.
