Description

Technical Field

[0001] The utility model relates to the technical field of catalyst production, in particular to a catalyst spraying device. Background Art

[0002] The impregnation method involves immersing a solid powder or a preformed solid of a certain shape and size (a carrier or a catalyst containing a main body) in a soluble compound solution containing active components (primary and co-catalyst components). After a certain period of contact, the residual liquid is separated, and the active components adhere to the solid in the form of ions or compounds. In the production of activated catalysts using a spray immersion device, a stirring shaft is usually installed within the device to ensure that the catalyst carrier at the bottom of the device can contact the sprayed soaking liquid. This is to enhance the fluidity of the catalyst carrier through stirring. However, when such a device is used, the stirring shaft is prone to excessive stirring, resulting in excessive tumbling force on the catalyst carrier, which can cause the catalyst carrier to break.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-2 4. A catalyst spraying device includes a barrel body 1, which is mounted on a flip module. The flip module is used to flip the barrel body 1; the flip module includes a base 12, a support plate 13, a transverse shaft 14, and a rotating motor 17. Two support plates 13 are fixed to the base 12, and a transverse shaft 14 is rotated on each of the two support plates 13. The two transverse shafts 14 are coaxially arranged, and the barrel body 1 is fixed between the two transverse shafts 14. The transverse shaft 14 is connected to the rotating motor 17. The flip module is provided because the barrel body 1 is in a horizontal state during normal operation, which makes it inconvenient to load the catalyst carrier into the storage cylinder 3 and pour out the stored agent carrier. For this purpose, the flip module is provided. When loading the catalyst carrier, the drum is directly rotated with the open end facing upward. In this way, after opening the barrel cover 6, the catalyst carrier can be loaded into the storage cylinder 3. Conversely, the barrel body 1 is rotated to a state where the open end faces downward. After opening the barrel cover 6, the catalyst in the storage cylinder 3 will pour out by itself. A barrel cover 6 is installed at the open end of the barrel body 1, and a rotating shaft 8 is coaxially installed at the closed end of the barrel body 1. A turntable 2 is coaxially fixed on the rotating shaft 8 in the barrel body 1. Several storage cylinders 3 are arranged around the central axis of the barrel body 1 between the turntable 2 and the barrel cover 6. One end of the storage cylinder 3 is rotatably connected to the turntable 2, and the other end of the storage cylinder 3 is coaxially fixed with an outer gear ring 4. An inner gear ring 5 is coaxially fixed in the barrel body 1, and the outer gear ring 4 is engaged with the inner gear ring 5. The rotating shaft 8 is transmission-connected to the drive motor 9, and a spray module is provided in the barrel body 1.

[0020] The storage cylinder 3 is cylindrical, and a plurality of long through grooves are formed on its surface along the circumference. The long through grooves can obtain more probability of contact with the soaking liquid and obtain better soaking effect.

[0021] The end of the storage barrel 3 away from the turntable 2 is attached to the barrel cover 6. The barrel cover 6 has a plurality of discharge ports corresponding to the storage barrels 3, each of which is mounted with a plug 7. When the plug 7 is installed, the filling port of the storage barrel 3 can be exposed by simply opening the barrel cover 6 without opening the barrel cover 6 directly, making loading and unloading easier.

[0022] Example 2: Reference Figure 3 、 5Another preferred embodiment of the present invention differs from Example 1 in that the spray module includes a main spray pipe 16 and auxiliary spray pipes 15. The main spray pipe 16 is coaxially arranged within the barrel body 1 and is fixedly connected to the barrel cover 6. Several auxiliary spray pipes 15 are arranged between the storage barrel 3 and the barrel body 1, surrounding the central axis of the barrel body 1. The auxiliary spray pipes 15 are fixedly connected to the barrel body 1 and are both connected to the soaking liquid supply device. By providing the main spray pipe 16 and auxiliary spray pipes 15, soaking liquid can be sprayed into the storage barrel 3 from both the inside and outside of the storage barrel 3, thereby achieving a better spraying effect.

[0023] It also includes a collecting box 10, which is fixed to the lower part of the barrel body 1. The collecting box 10 is connected to the interior of the barrel body 1. A liquid outlet pipe 11 is provided at the bottom of the collecting box 10, and the liquid outlet pipe 11 is used to connect to the soaking liquid circulation pool. Part of the soaking liquid after spraying flows into the collecting box 10 under the action of gravity, and is guided to the liquid outlet pipe 11 with the help of a slope, and finally flows to the soaking liquid circulation pool. The soaking liquid supply device extracts the soaking liquid in the soaking liquid circulation pool and sprays it again, so that the circulating spraying of the soaking liquid can be achieved. A slope is provided in the collecting box 10, and the slope is inclined toward the side away from the liquid outlet pipe 11.

[0024] When the utility model is in use, after the catalyst carriers to be impregnated are divided into multiple storage cylinders 3 one by one, the drive motor 9 is started, and the drive motor 9 drives the rotating shaft 8 to drive the turntable 2 to rotate, and the turntable 2 drives the multiple storage cylinders 3 thereon to revolve around the central axis of the barrel body 1. During the revolution, the outer gear ring 4 on the storage cylinder 3 drives the storage cylinder 3 to rotate under the drive of the inner gear ring 5. At this time, the main spray pipe 16 and the auxiliary spray pipe 15 are used to synchronously spray the soaking liquid toward both sides of the storage cylinder 3, so that the catalyst carrier in the storage cylinder 3 can quickly absorb the soaking liquid, and the efficiency is greatly improved. At the same time, it can also prevent the catalyst carrier from being excessively stirred and broken.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
