Description

Technical Field

[0001] The utility model belongs to the technical field of extractors, in particular to a low-speed, low-lift and high-efficiency extraction reactor. Background Art

[0002] Extractors, also known as extraction equipment, are a type of mass transfer equipment used for extraction operations. They can achieve perfect separation of components contained in the feed liquid. Extractors are widely used in chemical industry, metallurgy, petroleum, medicine, food, feed, detergents, rubber and plastic polymers, soil analysis and other fields.

[0003] However, there are some problems with the existing technology: in the existing extractor, the feed liquid and organic are added in a three-way form. This method can only feed evenly when the feed pressure of the organic and feed liquid is balanced, which is impossible to achieve in the actual production process. In addition, the existing extractor uses a static mixer for pre-mixing, and when the ratio of organic and feed liquid is different, blockage often occurs, affecting the later extraction rate, which is sometimes high and sometimes low. Therefore, we propose a low-speed, low-head, and high-efficiency extraction reactor. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the utility model is to provide a low-speed, low-lift, and high-efficiency extraction reactor. By setting a first-level inlet shell and a second-level inlet pump body and providing various impellers, the material is actively fed by the suction of the impeller. Before the organic and liquid materials are pre-mixed, they do not come into contact in advance in the extractor, so that the organic and liquid materials do not come into contact in advance in the extractor before being pre-mixed, and the feeding is uniform.

[0005] The utility model is implemented as follows: a low-speed, low-lift, and high-efficiency extraction reactor comprises a base, an upper end of the base is fixedly connected to a bracket, the bracket is fixedly connected to an outer shell, the outer shell comprises a first-stage inlet shell, a second-stage inlet pump body, a third-stage shell and a final-stage shell, the first-stage inlet shell, the second-stage inlet pump body, the third-stage shell and the final-stage shell are fixedly connected in sequence, the upper end of the base is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected in the outer shell, and one end of the outer shell is fixedly connected to a sealed cabin.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model is provided with a primary inlet shell and a secondary inlet pump body. Before the organic and liquid materials are pre-mixed, they do not come into contact in advance in the extractor and have no contact time, which can avoid the formation of the third phase and crystals in the later stage, and over-mixing of the organic and liquid materials. They are respectively cut and crushed by their own impellers in their respective cavities to reach a micro-state of appropriate size, thereby increasing the surface activity of the liquid particles and expanding the interface of mutual contact between the liquids.

[0013] 2. The utility model adopts a dual-inlet feeding method on the same extractor, wherein the first-level inlet shell feeds organic, and the second-level inlet pump body feeds liquid.

[0014] 3.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the low-speed, low-lift, and high-efficiency extraction reactor provided by the embodiment of the utility model includes a base 1. The base 1 is rectangular and made of stainless steel. The main function of the base 1 is to support the entire device.

[0023] Furthermore, a bracket 2 is fixedly connected to the upper end of the base 1, and a shell 3 is fixedly connected to the bracket 2. The shell 3 is cylindrical as a whole and is made of stainless steel. The main function of the shell 3 is to provide a mixing space for organic matter and liquid.

[0024] Furthermore, the housing 3 includes a first-stage inlet casing 301, a second-stage inlet pump body 302, a third-stage inter-stage casing 303 and a final-stage casing 304, and the first-stage inlet casing 301, the second-stage inlet pump body 302, the third-stage inter-stage casing 303 and the final-stage casing 304 are fixedly connected in sequence.

[0025] Furthermore, a support plate 8 is fixedly connected to the first-stage inlet housing 301 , the rotating shaft 5 is rotatably connected to the support plate 8 , and a first cutting and crushing impeller 9 is fixedly connected to the rotating shaft 5 . The first cutting and crushing impeller 9 is disposed in the first-stage inlet housing 301 .

[0026] Specifically, the organic matter enters the outer shell 3 through the primary inlet shell 301. When the motor 4 is started, it drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first cutting and crushing impeller 9 to rotate. When the first cutting and crushing impeller 9 rotates, suction is generated to suck the organic matter into the primary inlet shell 301, thereby achieving uniform feeding and more precise quantity control. At the same time, the first cutting and crushing impeller 9 will cut and stir the organic matter during rotation, so that the organic matter reaches a micro-state of appropriate size, thereby increasing the surface activity of the liquid particles, expanding the interface between the liquids in contact with each other, and facilitating subsequent mixing.

[0027] Furthermore, a discharge chamber is opened on one side of the secondary inlet pump body 302, and a second cutting and crushing impeller 10 is rotatably connected in the discharge chamber. The second cutting and crushing impeller 10 is fixedly connected to the rotating shaft 5. A conveying blade 11 is provided on the outside of the secondary inlet pump body 302, and the conveying blade 11 is fixedly connected to the rotating shaft 5.

[0028] Specifically, the feed liquid enters the housing 3 through the secondary inlet pump body 302. The secondary inlet pump body 302 isolates the feed liquid from the organic matter, so that the organic matter and the feed liquid do not come into contact in advance in the extractor before being pre-mixed. There is no contact time, which can avoid the formation of the third phase and crystals and over-mixing in the later stage.

[0029] Furthermore, a discharge cavity is opened on one side of the secondary inlet pump body 302 and a second cutting and crushing impeller 10 is provided. Driven by the motor 4 and the rotating shaft 5, it also generates suction to suck the organic matter into the primary inlet shell 301, thereby achieving uniform feeding and more precise quantity control. At the same time, the first cutting and crushing impeller 9 will cut and stir the organic matter during rotation, so that the organic matter reaches a micro-state of appropriate size, thereby increasing the surface activity of the liquid particles, expanding the interface between the liquids, and facilitating subsequent mixing.

[0030] Furthermore, a conveying blade 11 is provided on the outside of the secondary inlet pump body 302 and rotates synchronously under the drive of the motor 4 and the rotating shaft 5, so that the organic matter and the feed liquid are mixed and forced to be mixed under the action of the conveying blade 11.

[0031] Furthermore, the three-stage intershell 303 includes a first intershell 3031 and a second intershell 3032, the first intershell 3031 and the second intershell 3032 are fixedly connected, the inner wall of the first intershell 3031 is fixedly connected to the partition 12, and the first intershell 3031 and the second intershell 3032 are rotatably connected to the guide vanes 13, and the guide vanes 13 are fixedly connected to the rotating shaft 5.

[0032] Specifically, the organic and feed liquids are mixed and flow into the first shell 3031, achieving the first collision and mixing of multiple streams between the liquids. Then, the mixed liquid flows into the second shell 3032 through the guide vanes 13 in the first shell 3031 driven by the motor 4 and the rotating shaft 5, completing the secondary collision and mixing.

[0033] Furthermore, the outlet pump body 305 is fixedly connected to the upper end of the final stage casing 304 , and the sealed cabin 7 is fixedly connected to the final stage casing 304 .

[0034] Specifically, the mixed liquid that has completed the secondary collision mixing flows into the outlet pump body 305 and the final stage casing 304 through the guide vanes 13 in the second intermediate shell 3032 driven by the motor 4 and the rotating shaft 5, undergoes the third collision mixing, and is then transported out through the outlet pump body 305.

[0035] Furthermore, a motor 4 is fixedly connected to the upper end of the base 1 , and a rotating shaft 5 is fixedly connected to the output end of the motor 4 . The rotating shaft 5 is rotatably connected in the housing 3 .

[0036] Specifically, the motor 4 adopts a low speed of about 500r / min and a low lift design, which avoids the emulsification of the oil due to the high-speed operation of the impeller and reduces the failure rate of the reactor.

[0037] Furthermore, one end of the shell 3 is fixedly connected to a sealed cabin 7, a mechanical seal 14 is provided in the sealed cabin 7, the upper end of the sealed cabin 7 is connected to a water inlet pipe 15, and the lower end of the sealed cabin 7 is connected to a water outlet pipe 16. The sealed cabin 7 ensures the sealing of the shell 3, making the device safer.

[0038] Specifically, the mechanical seal 14 consists of a dynamic ring, a static ring, a spring, a sealing ring, and other components. It relies on the pressure of the fluid medium and the elastic force of the elastic fluid to generate appropriate compressive force on the contact surface, thereby achieving a sealing effect. The water inlet pipe 15 and the water outlet pipe 16 are used to introduce and discharge cooling water into and out of the sealed chamber 7. The water inlet pipe 15 is connected to the water tank to provide cooling water to the sealed chamber 7, while the water outlet pipe 16 discharges the used cooling water, forming a circulation system. The above is a conventional double-end external circulation water cooling mechanical seal structure, which is believed to be well understood by those skilled in the art and will not be further described here.

[0039] The working principle of this utility model is as follows:

[0040] The utility model is provided with a primary inlet housing 301 and a secondary inlet pump body 302. Before the organic and liquid materials are pre-mixed, they do not come into contact in advance in the extractor and have no contact time, which can avoid the formation of a third phase and crystals in the later stage and excessive mixing of the organic and liquid materials. Under the action of the first cutting and crushing impeller 9 and the second cutting and crushing impeller 10, they reach a micro-state of appropriate size in their respective cavities, thereby increasing the surface activity of the liquid particles and expanding the interface between the liquids in contact with each other.

[0041] The utility model adopts a dual-inlet feeding method on the same extractor, wherein the first-level inlet shell 301 feeds organic matter, and the second-level inlet pump body 302 feeds liquid. The feeding power of the two does not rely on their own pressure, but on the suction force generated by the operation of the first cutting and crushing impeller 9 and the second cutting and crushing impeller 10 to actively feed the material, so that the feeding is more uniform and the amount control is more accurate.

[0042] The utility model achieves uniform mixing of the liquid feed and the organic matter by collision mixing the mixed liquid multiple times, and at the same time reasonably controls the rotation speed of the motor 4, that is, the stirring intensity, so that the use of the extractant is more reasonable and sufficient, thereby greatly reducing the amount of organic matter stored in the tank, thereby improving the extraction rate and avoiding the safety hazards caused by the storage of a large amount of organic matter.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
