Description

Technical Field

[0001] The utility model relates to a high-temperature Hoffman pipeline reaction mixer. Background Art

[0002] At present, in the high-temperature Hoffman pipeline reaction process, sufficient mixing of materials is a key step to ensure the smooth progress of the reaction and efficient conversion. However, when the mixers configured in the existing technology cope with this task, there is generally a problem of insufficient material mixing, which directly leads to a significant decrease in the reaction yield. The design of traditional pipeline mixers is often based on the principles of fluid dynamics, and promotes the mixing of materials by changing parameters such as fluid velocity, direction and pressure. However, in the high-temperature Hoffman pipeline reaction, since the materials usually have high temperature and pressure and may contain a variety of different physical and chemical properties, such as solid particles and high-viscosity liquids, the effectiveness of these traditional mixing methods is greatly reduced.

[0003] After searching, it was found that the Chinese invention patent with authorization announcement number CN115646423B discloses a high-temperature Hoffman pipe reactor. The patent includes a cavity, a pipe, a stirring mechanism and a driving mechanism. The stirring mechanism is designed through an intermediate shaft, a support frame and a stirring paddle. The stirring paddle has a bending portion and a water hole, so that the heat-conducting medium can impact the pipe in multiple directions, thereby improving the heat exchange efficiency and stability; however, the patent only stirs the materials after they enter the reactor. Since they are not processed by a mixer, multiple materials accumulate inside the reactor, which increases the burden on the reactor and the reaction is not sufficient, resulting in a low yield.

[0053] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0054] Example 1

[0055] like Figure 1-4 As shown, the high temperature Hofman pipeline reaction mixer includes:

[0056] Pipeline reactor body 1;

[0057] Mixer body 2;

[0058] A delivery pipe 3 connecting the pipeline reactor body 1 and the mixer body 2;

[0059] The mixer body 2 includes a feed pipe 4, a processing chamber 1 5 and a processing chamber 2 6 which are connected in sequence and have interconnected internal spaces. The processing chamber 2 6 is connected to the delivery pipe 3.

[0060] The feed pipe 4 is provided with two feed ports 41, and a feed channel 42 is provided in the feed pipe 4 and communicates with the inner space of the processing chamber 1 5;

[0061] Mixing assembly 1 7, which includes a driving assembly 1, a mixing disc 72, and a baffle 74. The baffle 74 is fixedly connected to the processing chamber 1 5. One end of the mixing disc 72 is rotatably mounted on the inner wall of the processing chamber 5 near the feed channel 42, and the other end of the mixing disc 72 is rotatably mounted on one side of the baffle 74.

[0062] The driving assembly 1 is installed on the processing chamber 1 5, and the driving assembly 1 is connected to the mixing disk 72 to drive the mixing disk 72 to rotate in the processing chamber 1 5;

[0063] The mixing disc 72 is provided with a plurality of mixing troughs 73 , which are adapted to rotate to drive the plurality of mixing troughs 73 to communicate with the feed channel 42 in sequence. The baffle 74 is provided with a through slot, which is adapted to rotate to drive the plurality of mixing troughs 73 to communicate with the through slot in sequence.

[0064] like Figure 4 As shown, the driving assembly 1 includes a driving motor 71 and a rotating shaft 75;

[0065] The driving motor 71 is installed on the processing chamber 5, and the driving motor 71 is connected to the rotating shaft 75 to drive the rotating shaft 75 to rotate in the processing chamber 5;

[0066] The rotating shaft 75 passes through the baffle 74 and is connected to the mixing disk 72 .

[0067] like Figure 4 As shown, the outside of the rotating shaft 75 is connected to the auger 8.

[0068] like Figure 5 As shown, a mixing assembly 2 9 is provided on the baffle 74 , and the mixing assembly 2 9 includes a connecting component and a turning roller 94 ;

[0069] The connecting member is adapted to connect the flipping roller 94 and the rotating shaft 75;

[0070] The rotating shaft 75 is suitable for driving the flip roller 94 to rotate around the axis of the rotating shaft 75 .

[0071] like Figure 5 As shown, the connecting parts include a connecting rod 92, an internal gear sleeve 91 and a gear 93;

[0072] One end of the connecting rod 92 is fixedly sleeved on the outer circumference of the rotating shaft 75, the inner gear sleeve 91 is arranged on one side of the baffle 74, and the gear 93 is rotatably mounted on the other end of the connecting rod 92;

[0073] The turning roller 94 is connected to the gear 93 , and the gear 93 is meshed with the inner gear sleeve 91 .

[0074] like Figure 5 As shown, a partition 10 is provided in the feed pipe 4 , and the partition 10 is suitable for dividing the feed channel 42 , and the feed channel 42 is divided into channel 1 and channel 2, and channel 1 and channel 2 correspond to the two feed ports 41 respectively.

[0075] The working principle of this embodiment is as follows:

[0076] When needed, the two materials are respectively put into the feed pipe 4 through the two feed ports 41, enter the processing chamber 1 5 through the feed channel 42, and are mixed by the mixing component 1 7 and the mixing component 2 9 in the processing chamber 1 5. After the mixing is completed in the processing chamber 1 5, the materials continue to flow into the interior of the processing chamber 2 6, and are finally mixed by the mixing component 3 11 in the processing chamber 2 6. After all the processing is completed, they enter the interior of the pipeline reactor body 1 through the delivery pipe 3. The interior of the pipeline reactor body 1 is a tubular, continuously operated reactor with a large aspect ratio, which can be a single tube or multiple tubes in parallel to carry out chemical reactions. This part is a prior art and will not be described in detail here.

[0077] When the materials enter the feed channel 42, they are separated by the partition 10 in the feed channel 42, so that the two different materials will not be mixed before entering the corresponding mixing tank 73. The two materials have different qualities. If they are mixed before entering the mixing tank 73, the amount of the two materials may differ too much. Mixing in the mixing tank 73 can minimize the difference, thereby improving the uniformity of mixing.

[0078] After the drive motor 71 is started, it drives the rotating shaft 75 to rotate, and the rotating shaft 75 drives the mixing disk 72 to rotate. When the mixing disk 72 rotates, the mixing grooves 73 on it dock with the feeding channel 42 one by one. The two materials are stably mixed in each mixing groove 73 and enter the interior of the processing chamber 5. This arrangement ensures that the two materials are quantitatively and stably fed into the processing chamber 5 when the difference in the mixing amount is not large, thus avoiding accumulation and improving the mixing effect.

[0079] It should be noted that the two surfaces of the mixing disk 72 are respectively attached to the inner wall of the processing chamber 5 and one side of the baffle 74, so that all the mixing troughs 73 are in a closed state and can only be connected to the feed channel 42 one by one. There is only one place for material to be dropped into the processing chamber 5. This arrangement ensures that the material entering the mixing trough 73 can only enter the processing chamber 5 through the rotation of the mixing disk 72, thereby preventing premature leakage.

[0080] After entering the processing chamber 1 5 , the material passes through the through slot on the baffle 74 . After passing through the through slot, the mixing assembly 2 9 further mixes the material. The principle of the mixing assembly 2 9 is that the rotating shaft 75 drives the connecting rod 92 to rotate, and the connecting rod 92 further drives the turning roller 94 to revolve around the axis of the rotating shaft 75 . The material is stirred during the revolution. On this basis, the gear 93 meshes with the inner gear disc to realize the self-rotation of the turning roller 94, further improving the effect of the turning roller 94 in turning the material and promoting mixing.

[0081] After the mixing process of mixing component 1 7 and mixing component 2 9, the material is transported to the interior of processing chamber 2 6 through the continuously rotating auger 8 for the next mixing work. In addition to the function of transporting materials, the auger 8 also has the ability of stirring, which can help the mixing. At the same time, the auger 8 has the effect of crushing the fixed particle material, and the mixing after crushing will be more comprehensive.

[0082] Example 2

[0083] like Figure 6 As shown, this embodiment further includes the following structures based on the embodiment 1: a mixing assembly 3 11 is provided in the processing chamber 2 6, and the mixing assembly 3 11 includes a driving assembly 2 and a stirring blade assembly;

[0084] The second driving component is installed on the second processing chamber 6 , and the second driving component is connected to the stirring blade group to drive the stirring blade group to rotate in the second processing chamber 6 .

[0085] like Figure 6 As shown, the second driving assembly includes a second driving motor 1101 and a rotating rod 1104;

[0086] The second driving motor 1101 is installed on the second processing chamber 6, and the second driving motor 1101 is connected to the rotating rod 1104 to drive the rotating rod 1104 to rotate.

[0087] like Figure 6 As shown, the stirring blade group includes an outer spiral stirring blade 1102 and an inner spiral stirring blade 1103, and the outer spiral stirring blade 1102 and the inner spiral stirring blade 1103 are fixedly sleeved on the outer circumference of the rotating rod 1104;

[0088] The outer spiral ribbon stirring blade 1102 and the inner spiral ribbon stirring blade 1103 are both inclined, and the inclination directions are opposite.

[0089] like Figure 6 As shown, the outer spiral ribbon stirring blade 1102 is provided with scrapers 12 arranged at intervals, and the side of the scraper 12 away from the rotating rod 1104 is in contact with the inner wall of the processing chamber 2 6.

[0090] The working principle of this embodiment is as follows:

[0091] After the material enters the processing chamber 2 6, the final mixing work is completed under the processing of the mixing component 3 11. The driving motor 2 1101 in the mixing component 3 11 is started, driving the rotating rod 1104 to rotate, thereby driving the outer spiral stirring blade 1102 and the inner spiral stirring blade 1103 to rotate. The outer spiral stirring blade 1102 and the inner spiral stirring blade 1103 are inclined, and the inclination direction is opposite. Therefore, during the rotation process, the material is divided into two parts. The two parts move in opposite directions and reverse the direction of movement again after moving to the extreme position. In this way, a better mixing effect is achieved under reciprocating motion. This part is a prior art and will not be described in detail here.

[0092] In addition, during the rotation of the outer spiral stirring blade 1102, the scraper 12 is driven to continuously scrape the inner wall of the processing chamber 2 6 to prevent the material from sticking, playing a self-cleaning role, reducing material waste and avoiding contamination when other materials are subsequently added for reaction;

[0093] After all the materials have been processed, the electrically controlled valve at the bottom of the second processing chamber 6 is opened, and the materials are fed into the interior of the pipeline reactor body 1 through the delivery pipe 3 for high-temperature reaction.

[0094] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
