The device includes a feeding pipe installed at the lower end of the feed inlet, a drive shaft installed at the midpoint of the inner cavity of the feeding pipe, feeding blades installed on the surface of the drive shaft, and a motor installed at the left end of the drive shaft. A discharge trough is provided on the lower surface of the right end of the feeding pipe. Connecting plates are evenly installed at the lower end of the feed inlet, and an upper base is installed at the lower end of the connecting plates. An upper fixing block is evenly installed on the left side of the lower surface of the upper base, and an upper support rod is installed on the upper fixing block.

This greatly improves the reaction effect of the catalyst on the material, and the feeding effect is better. It effectively solves the problem that existing catalyst feeding devices cannot screen out catalysts with larger particles, which easily affects the reaction rate of the material when feeding the catalyst.

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] 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.

[0021] This utility model provides a catalyst feeding device, such as... Figure 1-3 As shown, the catalyst feeding device includes: a cylinder 1 with a discharge port, a first rotating shaft 2 rotatably mounted on the cylinder 1, and a spiral blade 4 fixedly sleeved on the first rotating shaft 2; a first motor 3 fixedly mounted on one side of the cylinder 1, the output shaft of the first motor 3 being connected to the first rotating shaft 2 via a first coupling; a feed hopper 5 fixedly mounted on the cylinder 1 for storing catalyst, the feed hopper 5 being connected to the interior of the cylinder 1; and a screening mechanism for screening catalyst assembled on the feed hopper 5.

[0022] In this embodiment, when using this device to feed the catalyst, the catalyst to be used is first poured into the feed hopper 5. After pouring, the discharge port on the cylinder 1 is aligned with the feed port of the existing reaction equipment. After alignment, the first motor 3 is started. The first motor 3 drives the first rotating shaft 2 to rotate through the first coupling. The first rotating shaft 2 can not only drive the spiral blade 4 to rotate, but also drive the screening mechanism to operate, so that the screening mechanism can screen the catalyst. Catalyst with qualified particle size will pass through the screening mechanism and enter the cylinder 1. Then, under the push of the spiral blade 4, it can be discharged from the discharge port, thereby realizing the feeding operation. Catalyst with unqualified particle size will be intercepted inside the feed hopper 5. This can greatly improve the reaction effect of the catalyst on the material, and the feeding effect is better.

[0023] In a further preferred embodiment of this utility model, the screening mechanism includes: a plurality of housings 6 fixedly installed on the inner wall of the feed hopper 5, each of the top inner walls of the plurality of housings 6 being fixedly installed with a spring 7; a plurality of support rods 8 slidably installed on the plurality of housings 6, each of the top ends of the plurality of support rods 8 being fixedly installed with a baffle 9, the plurality of baffles 9 respectively contacting the plurality of springs 7; a screen 10 fixedly installed at the bottom end of the plurality of support rods 8; a second rotating shaft 11 rotatably installed on the feed hopper 5, the second rotating shaft 11 being fixedly fitted with a cam 12, the cam 12 contacting the screen 10; and two sprockets 13 fixedly fitted on the first rotating shaft 2 and the second rotating shaft 11 respectively, the two sprockets 13 being fitted with the same chain 14.

[0024] In this embodiment, the screening mechanism is used to screen the catalyst. During the process of the first motor 3 driving the first rotating shaft 2 to rotate, the first rotating shaft 2 will drive the second rotating shaft 11 to rotate through two sprockets 13 and a chain 14. The second rotating shaft 11 will drive the cam 12 to rotate. The cam 12 will continuously push the screen 10, so that the screen 10 can achieve the screening of the catalyst through reciprocating up and down movement. The catalyst with qualified particle size will pass through the screen 10 and enter the cylinder 1. Then, under the push of the spiral blade 4, it can be discharged from the outlet. The catalyst with unqualified particle size will be intercepted by the screen 10 inside the feed hopper 5. This can greatly improve the reaction effect of the catalyst on the material and the feeding effect is better. When the screen 10 is squeezed by the cam 12, the multiple support rods 8 connected to the screen 10 will drive the multiple baffles 9 to squeeze the multiple springs 7. When the cam 12 does not squeeze the screen 10, the multiple springs 7 will push the multiple baffles 9 downward through their own elasticity. The multiple baffles 9 will drive the multiple support rods 8 to slide on the multiple housings 6. The multiple support rods 8 will push the screen 10 back to its original position, and so on.

[0025] In a further preferred embodiment of the present invention, the catalyst feeding device further includes a lifting mechanism installed on the cylinder 1 for adjusting the height of the discharge port.

[0026] In this embodiment, the height of the discharge port can be adjusted according to the feed inlet of different reaction equipment by using a lifting mechanism.

[0027] In a further preferred embodiment of this utility model, the lifting mechanism includes: a bottom shell 15 disposed below the cylinder 1, on which a screw 16 is rotatably mounted; a second motor 17 fixedly mounted on one side of the bottom shell 15, the output shaft of the second motor 17 being connected to the screw 16 via a second coupling; a slider 18 threadedly mounted on the screw 16, the slider 18 being slidably connected to the inner wall of the bottom shell 15; and a hinge rod 19 hinged to the slider 18, one end of the hinge rod 19 being hinged to the bottom of the cylinder 1.

[0028] In this embodiment, when the lifting mechanism is in use, the second motor 17 is started, and the second motor 17 drives the screw 16 to rotate through the second coupling. The screw 16 drives the slider 18 to slide horizontally on the inner wall of the bottom shell 15. The slider 18 drives the hinge rod 19 to rotate at the bottom of the cylinder 1, thereby adjusting the height of the cylinder 1 so that the discharge port on the cylinder 1 can be used at a suitable height to meet the needs of different reaction equipment.

[0029] In a further preferred embodiment of the present invention, a base plate is fixedly installed at the bottom of the bottom shell 15, a caster wheel is fixedly installed at the bottom of the base plate, and a handrail is fixedly installed at the top of the base plate.

[0030] In this embodiment, the combined use of multiple casters and multiple handrails allows personnel to easily push the device by hand to move it to a suitable position for use.

[0031] In a further preferred embodiment of the present invention, a plurality of telescopic rods 20 are fixedly installed on the top of the bottom shell 15, and the top ends of the plurality of telescopic rods 20 are all fixedly connected to the bottom of the cylinder 1.

[0032] In this embodiment, the use of multiple telescopic rods 20 can improve the stability of the cylinder 1 during vertical lifting. When the cylinder 1 is vertically lifted, the multiple telescopic rods 20 connected between the cylinder 1 and the bottom shell 15 will also extend and retract simultaneously, which can prevent the cylinder 1 from tilting.

[0033] In a further preferred embodiment of the present invention, the screen 10 is made of stainless steel, and the spiral blade 4 is in contact with the inner wall of the cylinder 1.

[0034] In this embodiment, the stainless steel screen 10 has good corrosion resistance and durability, and a good service life.

[0035] In summary, compared with related technologies, this solution, through the use of the feed hopper 5, can store a large amount of catalyst. The first motor 3 not only drives the first rotating shaft 2 to rotate the spiral blades 4, but also drives the screening mechanism. This allows the screening mechanism to screen the catalyst, allowing catalysts of suitable particle size to pass through the screening mechanism and enter the cylinder 1. Then, driven by the spiral blades 4, they can be discharged from the outlet, thus achieving the feeding process. Catalysts of unsuitable particle size are intercepted inside the feed hopper 5, which greatly improves the reaction effect of the catalyst on the material. The feeding effect is better, effectively solving the problem that existing catalyst feeding devices cannot screen out larger catalyst particles, thus easily affecting the reaction rate of the material during catalyst feeding.

[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
