Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to a surfactant mixing and dispersing equipment. Background Art

[0002] Surfactants are organic compounds with fixed hydrophilic and lipophilic groups, which can be arranged in a directional manner on the surface of a solution and can significantly reduce the surface tension. Known as "industrial MSG", they are a very important class of chemicals with a wide range of applications and great practical value.

[0003] During the production process of surfactants, mixing equipment is usually required to stir and mix various raw materials.

[0004] A solid-liquid mixing device for preventing caking of surfactants prepared in Chinese patent CN115121176A includes a mixing box, a side wall of which is fixedly connected to a liquid discharge pipe, an upper end surface of the mixing box is provided with a cover plate, a rotating shaft is penetrated through the cover plate, a fixed pipe is sleeved on the side wall of the rotating shaft, and a liquid injection pipe is fixedly penetrated through the side wall of the fixed pipe.

[0005] However, compared with the prior art and the comparative scheme, it can be seen that the mixing device still has the following problems during actual use: In the process of surfactant production, the raw materials are divided into dry powder and liquid. Different types of liquid raw materials have different densities. Different types of liquid raw materials may be stratified during the stirring and dispersion process, resulting in insufficient mixing of the raw materials. When the dry powder raw materials and liquid raw materials are mixed and stirred, due to the "tea leaf paradox" (the phenomenon of tea leaves when stirred in a teacup: the tea leaves will swim to the center of the bottom of the cup, rather than being pushed to the edge of the bottom of the cup as expected under the action of spiral centrifugal force), the dry powder raw materials will gather in the middle of the bottom of the mixing drum, affecting the mixing effect of the dry powder raw materials and the liquid raw materials.

[0023] The working process is as follows: S1. When in use, different raw materials are added into the mixing drum 1 through the feed pipe 105 and the manhole 104 respectively, and the first motor 21 is started. The first motor 21 drives the wall cleaning component 24 and the adaptive component 26 to rotate through the first connecting shaft 22, and the wall cleaning component 24 drives the auxiliary mixing component 25 to rotate, so as to stir and mix the raw materials in the mixing drum 1; S2. At the beginning of mixing, the liquid raw material with higher density is at the bottom of the mixing drum 1, while the liquid raw material with lower density is at the top of the mixing drum 1; S3. As the stirring begins, the solid raw materials in the mixing drum 1 gather in the middle of the bottom of the mixing drum 1 due to the "tea leaf paradox" phenomenon, so that the resistance of the guide plate 254 near the bottom is greater than the resistance of the guide plate 254 near the top, and the guide plate 254 changes from an inclined state to a vertical state (the state of the auxiliary mixing component 25 changes from Figure 7 Convert to Figure 8 ), at which time the first elastic member 246 contracts; S4. Since the guide plate 254 is spiral in shape, the upper and lower parts of the guide plate 254 twist in different directions. When the guide plate 254 rotates around the first connecting shaft 22 along with the wall cleaning assembly 24, the upper part of the guide plate 254 guides the surrounding liquid raw materials to flow toward the first connecting shaft 22, and the lower part of the guide plate 254 guides and pushes the solid raw materials gathered in the middle of the bottom of the mixing drum 1 toward the wall of the mixing drum 1, so that the raw materials inside the mixing drum 1 form a circulation between the inside and outside (such as Figure 5 shown); S5. After the solid raw material in the middle of the bottom of the mixing drum 1 is guided and pushed toward the wall of the mixing drum 1 by the lower part of the guide plate 254, the solid raw material flows to the position near the inner wall of the mixing drum 1. Since the position of the lower part of the guide plate 254 corresponds to the position of the upper part of the contact plate 265, the resistance of the upper part of the contact plate 265 rotating around the first connecting shaft 22 increases, so that the contact plate 265 drives the second rotating shaft 264 to rotate, the second elastic member 267 contracts, and the contact plate 265 changes from an inclined state to a vertical state, so that the raw material near the inner wall of the mixing drum 1 is stirred and mixed (the state of the adaptive component 26 changes from Figure 7 Convert to Figure 8 ); S6. At the same time, the second motor 301 and the third motor 401 are started. The second motor 301 drives the rotor 303 to rotate through the second connecting shaft 302. The third motor 401 drives the stirring disk 404 to rotate through the third connecting shaft 402 to emulsify and disperse the raw materials in the stirring drum 1. S7. After the various raw materials in the mixing drum 1 are preliminarily mixed, the upper and lower parts of the guide plate 254 are subjected to the same resistance, and the upper and lower parts of the contact plate 265 are subjected to the same resistance. Under the elastic action of the first elastic member 246 and the second elastic member 267, the guide plate 254 and the contact plate 265 are driven to change from a vertical state to an inclined state (the state of the auxiliary mixing mechanism 2 is changed from Figure 8 Convert to Figure 7 ); S8. When the guide plates 254 in the inclined state rotate around the first connecting shaft 22, the multiple inclined guide plates 254 will form an effect similar to a spiral auger, driving the raw materials in the middle of the mixing drum 1 to flow upward, while the spiral scraper 244 and the inclined contact plate 265 rotating around the first connecting shaft 22 drive the raw materials near the drum wall in the mixing drum 1 to flow downward, so that the raw materials in the mixing drum 1 form a circulation between the upper and lower parts (such as Figure 3 As shown), the mixing effect between the raw materials in the mixing drum 1 is improved.
