[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Example 1 of the auxiliary tool for loading catalyst in a tubular reactor provided by the utility model:

[0033] like Figures 1 to 5 As shown, the auxiliary tool for loading catalyst in the tubular reactor of the utility model comprises a tower-shaped spring plug 1 and a fixing rod. Figure 5As shown, a positioning rod 8 extending radially along the bottom surface of the spring plug 1 is integrally formed on the bottom surface.

[0034] The fixed rod includes a fixed rod section 3 and an extended rod section 15. An extended hole 18 is provided at one end of the fixed rod section 3 away from the extended rod section 15, and the extended hole 18 is a threaded hole; an extended joint 19 is provided at one end of the extended rod section 15 facing the extended hole 18, which is threadedly matched with the extended hole 18, and the extended joint 19 is threadedly connected in the extended hole 18.

[0035] In order to reduce the risk of workers pushing the catalyst into the tubular reactor 2, the end of the extended rod section 15 away from the fixed rod section 3 is connected to a connecting rod 16, and the end of the extended rod section 15 away from the fixed rod section 3 is provided with an auxiliary hole 20, which is a threaded hole; the end of the connecting rod 16 facing the extended rod section 15 is provided with an auxiliary joint 21 threadably matched with the auxiliary hole 20, and the auxiliary joint 21 is threadedly connected in the auxiliary hole 20. The end of the connecting rod 16 away from the extended rod section 15 is integrally connected with an operating rod 17 perpendicular to the connecting rod 16.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, a fixing head 9 is provided at one end of the fixing rod section 3 facing the spring plug 1, and a positioning groove 10 adapted to the positioning rod 8 is opened on the fixing head 9. The positioning groove 10 is used to clamp the positioning rod 8 to avoid rotational displacement or falling off of the fixing head 9 due to uneven lateral and radial forces during the filling process. At the same time, it can also avoid assembly failure of the spring plug 1 or depth (height) accuracy error caused by rotational displacement or falling off of the fixing head 9 during the filling process.

[0037] An assembly hole 11 adapted to the fixed rod segment 3 is formed at one end of the fixed head 9 close to the fixed rod segment 3, a fixing hole 12 is formed on the fixed head 9 and extends radially into the assembly hole 11, a positioning hole 13 corresponding to the fixing hole 12 is formed on the fixed rod segment 3, the positioning hole 13 is a threaded hole, a positioning pin 14 is passed through the fixing hole 12, the positioning pin 14 passes through the fixing hole 12 and is threadedly connected in the positioning hole 13.

[0038] A positioning plane 5 extending along the length direction of the fixed rod section 3 is provided, and a circular positioning plate 4 is coaxially provided on the fixed rod section 3. The positioning plate 4 is provided with a locking hole 6 perpendicular to the positioning plane 5 and extending to the positioning plane 5. A locking rod 7 is provided in the locking hole 6. The locking rod 7 is used to abut against the positioning plane 5 to fix the positioning plate 4.

[0039] In this embodiment, in order to improve the stability of the positioning plate 4 , the locking hole 6 is a threaded hole, and the locking rod 7 is a threaded rod threadably matched with the locking hole 6 .

[0040] The auxiliary tool for loading catalyst in the tubular reactor of the utility model is used, such as Figure 2 As shown, first adjust the positioning plate 4 to a suitable position on the fixed rod segment 3, then thread the locking rod 7 into the locking hole 6 and abut against the positioning plane 5. At this time, add the catalyst into the tube reactor 2, and then insert the spring plug 1 into the tube reactor 2. At this time, the staff can rotate the operating rod 17 to extend the fixed rod and the spring plug 1 into the tube reactor 2 until the positioning plate 4 is stopped by the end face of the feed end of the tube reactor 2, and the catalyst is pushed to the set depth.

[0041] When the auxiliary tool for filling catalyst in the tubular reactor of the utility model is in use, the positioning plate and the tubular reactor stop cooperate with each other, so that the catalyst can be pushed to the set depth in the tubular reactor every time, thereby facilitating the control of the filling depth of the catalyst, and the structure is simple and the operation is convenient.

[0042] Example 2 of the auxiliary tool for loading catalyst in a tubular reactor provided by the utility model:

[0043] The main difference between it and Example 1 is that: in Example 1, a positioning plane extending along its length direction is provided on the fixed rod section; a locking hole perpendicular to the positioning plane and extending to the positioning plane is provided on the positioning plate, and a locking rod is provided in the locking hole, and the locking rod is used to abut against the positioning plane to fix the positioning plate.

[0044] In this embodiment, the fixed rod segment is a threaded rod, and a threaded hole that matches the thread of the fixed rod segment is opened on the positioning plate. At this time, the staff can adjust the positioning plate to any position on the fixed rod segment by rotating the positioning plate to fill catalysts of different depths into the shell-and-tube reactor.

[0045] Example 3 of the auxiliary tool for loading catalyst in the tubular reactor provided by the utility model:

[0046] The main difference between it and Example 1 is that in Example 1, the locking hole is a threaded hole, and the locking rod is a threaded rod that is threadably matched with the locking hole.

[0047] In this embodiment, the locking hole is a pin hole, and the locking rod is a pin rod matched with the locking hole. At this time, the locking rod is inserted into the locking hole and abuts against the positioning plane.
