Description

Technical Field

[0001] The present application relates to the technical field of catalyst production, and in particular to a catalyst production mixing device. Background Art

[0002] In a chemical reaction, a substance that can change the chemical reaction rate of the reactants (increase or decrease) without changing the chemical equilibrium, and whose own quality and chemical properties do not change before and after the chemical reaction, is called a catalyst. According to statistics, catalysts are used in more than 90% of industrial processes, such as chemical, petrochemical, biochemical, environmental protection, etc. Catalysts occupy an extremely important position in the modern chemical industry.

[0003] In the field of catalyst production, manufacturers often need to mix and blend catalyst products according to customer requirements to achieve process goals. In particular, catalytic cracking catalyst (FCC) manufacturers need to supply corresponding catalysts according to the raw materials, product solutions and device characteristics of different refinery customers. Since products and raw materials are often adjusted, different catalysts and additives need to be mixed while changing the process; in addition, when indicators such as the particle size and density of the catalyst fluctuate within a certain range, further blending is required. The common mixing method usually uses a tank mixing device, which requires manual feeding, hydraulic cylinder turning, and manual discharging. The production process is labor-intensive, the operating efficiency is low, and it is easy to mix unevenly.

[0004] The utility model patent with the authorization announcement number CN214439069U disclosed in the Chinese patent literature discloses a "continuous catalyst preparation tank", and specifically discloses a preparation tank body including a cylindrical body, four support columns are welded on the bottom outer wall of the preparation tank body, and a plurality of feeding hoppers are arranged on the top of the preparation tank body. Each feeding hopper is provided with a connecting port at the connection between the bottom of the preparation tank body and the preparation tank body, and the preparation tank body is located at the center of the bottom inner wall and is rotatably connected to a rotating shaft through a bearing, and a rotating disk is coaxially welded on the top of the rotating shaft. The utility model is provided with a feeding device, which can feed the mixed catalyst into the feeding box through the feeding hopper. At this time, the catalyst is transported by the rotating auger blade driven by the motor, so that continuous production can be carried out in the preparation tank, which improves production efficiency. At the same time, the auger blade can further stir and mix the catalyst to improve the quality of the catalyst.

[0005] However, the prior art disclosed in the patent document cannot provide a corresponding number of feeding devices for different types of materials according to the needs of the prepared catalyst, and its scope of use is limited.

[0006] The above information disclosed in the above Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is already known to one of ordinary skill in the art.

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0033] In order to achieve the above purpose, refer to Figure 1 An embodiment of the present application provides a catalyst production mixing device, including a shell 1, a conveying and mixing device 2 and a plurality of feed hoppers 3; the conveying and mixing device 2 is arranged in the shell 1 to mix the materials in the shell 1 and convey the materials to a preset position; a plurality of feed ports 11 are arranged at intervals on the top of the shell 1 along the conveying direction of the conveying and mixing device 2, and the feed hopper 3 is detachably connected to the feed port 11, and the number of the feed port 11 is greater than the number of the feed hopper 3; a first flow meter 31 and a first solenoid valve 32 are arranged at the outlet end of the feed hopper 3.

[0034] The shell 1 of this embodiment is a pipeline structure, and a plurality of feed ports 11 are arranged at intervals along the extension direction of the top of the shell 1. Different amounts of catalysts and additives can be added as needed, and a corresponding number of feed hoppers 3 can be set. Through the detachable connection between the feed hoppers 3 and the shell 1, the distance between different feed hoppers 3 can be adjusted according to the physical properties or chemical properties of different catalysts and additives to achieve a better mixing effect.

[0035] The outlet end of the feed hopper 3 is provided with a first flow meter 31 and a first solenoid valve 32. The amount of the catalyst or auxiliary agent introduced into the shell 1 is obtained through the first flow meter 31, and the opening or closing of the outlet end of the feed hopper 3 can be accurately controlled through the first solenoid valve 32, thereby achieving accurate control of the amount of the catalyst or auxiliary agent introduced into the shell 1.

[0036] The conveying and mixing device 2 is installed inside the shell 1, and the conveying direction of the conveying and mixing device 2 is parallel to the axial direction of the shell 1, so that after the material enters the shell 1 from the feed hopper 3, it can be continuously driven in the same direction by the conveying and mixing device 2 inside the shell 1. In this process, the catalysts and additives entering the shell 1 from different feed hoppers 3 can be mixed.

[0037] In this way, different numbers of feeding devices can be set for the preparation of different catalysts or additives, which can be suitable for more working environments and working requirements.

[0038] Optionally, refer to Figure 2 In this embodiment, any feed port 11 is detachably provided with a sealing cover 12, and a filling block 13 is provided inside the sealing cover 12. The part of the filling block 13 entering the shell 1 cooperates with the shape of the inner wall of the shell 1, so that the shape of the inner wall of the shell 1 is complete.

[0039] When in use, the feed port 11 without the feed hopper 3 is sealed by setting a sealing cover 12 to prevent the catalyst or auxiliary agent in the shell 1 from partially exposing the shell 1; by setting a filling block 13 that matches the shape of the feed port 11 on the side of the sealing cover 12 close to the shell 1, part of the catalyst or auxiliary agent can be prevented from entering the gap between the sealing cover 12 and the feed port 11, resulting in deviations in the composition ratios between the various materials, resulting in poor quality of the final catalyst product.

[0040] By setting the bottom of the part where the filling block 13 enters the shell 1 to be an arc surface that matches the shape of the inner wall of the shell 1, when the installation between the sealing cover 12 and the shell 1 is completed, the bottom of the filling block 13 is flush with the inner wall of the shell 1, so that the shape of the inner wall of the shell 1 is complete.

[0041] Furthermore, the sealing cover 12 of the present embodiment is detachably connected to the shell 1 by means of threads. At the same time, a pointer or scale can be provided on the outside of the sealing cover 12 so that the angle between the filling block 13 and the inner wall of the shell 1 can be accurately adjusted so that after the sealing cover 12 and the shell 1 are installed, the bottom of the filling block 13 is flush with the inner wall of the shell 1, so that the shape of the inner wall of the shell 1 is complete.

[0042] At the same time, a rubber ring 14 can be arranged between the sealing cover 12 and the shell 1 to further enhance the sealing effect between the sealing cover 12 and the feed port 11. At the same time, a rubber ring 14 can be arranged on the side of the filling block 13 to further enhance the sealing effect between the filling block 13 and the feed port 11.

[0043] Optionally, the conveying and mixing device 2 of this embodiment includes a driving motor 22 and an auger 21 drivingly connected to the driving motor 22 , the shell 1 is a tubular structure, the auger 21 is arranged along the axis of the shell 1 , and the auger 21 abuts against the inner wall of the shell 1 .

[0044] The driving motor 22 of this embodiment is installed on the outside of the shell 1, and is used to drive the auger 21 to rotate. The auger is arranged in the shell 1, and the auger 21 is coaxially arranged with the shell 1. The edge of the auger 21 abuts against the inner wall of the shell 1, so that the catalyst and auxiliary agent inside the shell 1 can be driven to stir and displace at the same time by rotating the auger 21 until it moves to the discharge position connected to one end of the shell 1.

[0045] Among them, in actual use, the rotation direction of the auger 21 can be adjusted. When mixing is required, the auger 21 can be rotated in the reverse direction to move the catalyst raw materials and auxiliary agents to the end away from the outlet, which mainly plays a role in mixing the catalyst raw materials and auxiliary agents inside the shell 1. When the mixing is completed, the auger 21 is rotated forward to move the mixed catalyst raw materials and auxiliary agents to the end close to the outlet until the production mixing of the catalyst is completed.

[0046] Optionally, the edge of the auger 21 of the present embodiment is a frosted layer to enhance the friction between the auger 21 and the inside of the housing 1 .

[0047] The outside of the auger 21 may be provided with a wear-resistant soft material layer, and the inner wall of the shell 1 may be provided with a wear-resistant soft material layer, which may specifically be rubber or hard resin or other materials.

[0048] Optionally, a discharge hopper 4 is provided at the bottom of one end of the housing 1 of this embodiment; a second flow meter 41 and a second solenoid valve 42 are provided at the discharge end of the discharge hopper 4 .

[0049] By controlling the second solenoid valve 42 disposed on the discharge hopper 4, the two mixing modes can be adjusted.

[0050] Among them, the first mixing mode is: setting the discharge hopper 4 to be normally open, and controlling the opening degree of the first solenoid valve 32 of the feed hopper 3 to control different catalysts or auxiliary agents to enter the shell 1 at a certain speed. At this time, it is monitored by the first flow meter 31, and mixed and transported to the discharge hopper 4 at the same time through the auger 21, and can directly leave the shell 1 through the discharge hopper 4 to complete the mixing step.

[0051] The second mixing mode is: setting the discharge hopper 4 to be normally closed, controlling the first flow meter 31 and the first solenoid valve 32 of the feed hopper 3 to be used in conjunction, controlling a preset amount of catalyst or auxiliary agent to enter the shell 1, and mixing them in the shell 1, opening the discharge hopper 4 after the mixing is completed, and driving the mixed catalyst to leave the shell 1 through the auger 21.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
