Description

mixed reactor

The utility model belongs to the technical field of mixing, and relates to a mixer with a propeller-shaped rotating stirring device in a fixed container, in particular to a mixing reactor (B01F7/00).

In the actual use of existing mixing reactors, it is generally difficult to heat and keep the mixed materials in the container, or to cool down the temperature. When producing and processing products with relatively high temperature requirements, it is often difficult to ensure the quality of the products.

The purpose of the utility model is to provide a mixing reactor, which can conveniently heat, keep and cool the mixed material in the container, so as to overcome the shortcomings of the prior art.

The task of the utility model is accomplished in the following manner. A mixing reactor adopts the basic structure of a traditional mixing reactor as a whole. There is a spiral rotating stirring rod in the fixed container, and a container cover is arranged on the upper part of the fixed container. The bottom of the fixed container wall is provided with a discharge port, and the spiral rotating stirring rod is fixed on a suitable part of the container cover, and a feed port is opened on the container cover. The key is that the fixed container wall of the mixing reactor is double-layered. Structure, a heating jacket is formed between the inner wall and the outer wall of the fixed container wall, and a circulating water inlet and outlet is opened near the edge of the container cover, and the circulating water inlet and outlet are located between the inner wall and the outer wall of the fixed container wall to form a heating jacket top of the set.

The presence of the heating jacket enables the mixing reactor to conveniently heat, keep and cool the mixed material in the container. When heating is required, the circulating hot water is continuously injected into the circulating water inlet, and the circulating hot water enters the inside of the heating jacket, so that it can be heated and kept warm without changing the concentration of the mixed material in the container. The circulating water outlet is discharged outward; when cooling is required, the circulating cold water is continuously injected into the circulating water inlet, and the circulating cold water enters the heating jacket to cool it down without changing the concentration of the mixed material in the container. The circulating cold water will be discharged from the circulating water outlet.

In order to facilitate the control of the viscosity of the product, it is better to open another hot water inlet on the container cover, so that the predetermined hot water or corresponding solvent can be added to the mixed material in the container through the hot water inlet, and at the same time for It is convenient to observe the mixing condition of the mixed materials in the container, and an observation window can be set on the container cover.

Below in conjunction with the accompanying drawings shown in the embodiment the utility model is described in further detail.

It can also be seen from FIG. 1 that a hot water inlet 17 and an observation window 18 are simultaneously provided on the container cover 1 .

Referring to Fig. 3 and Fig. 4, a container cover 1 is arranged on the top of the fixed container 2 of the mixing reactor, and two helical rotating stirring rods 3 are respectively connected with a transmission shaft 32 through respective connecting rods 31, and the transmission shaft 32 passes through a bearing Seat 4 is fixed on the near central part of container cover 1, and transmission shaft 32, connecting pole 31 and spiral rotating stirring rod 3 are powered by motor 5 and motor 6 respectively, and transmission shaft 32, connecting pole 31, spiral rotating stirring The rod 3, the motor 5 and the motor 6 are all connected by a traditional connection method, and the container cover 1 is provided with feeding ports 11, 12, 13, 14, and the fixed container wall is also a double-layer structure, and the inner wall 21 and the outer wall of the fixed container wall A heating jacket 23 is formed between 22, a discharge port 24 is opened at the bottom of the fixed container 2, and a circulating water inlet 15 and a circulating water outlet 16 are respectively opened at the two near edges of the container cover 1.

It can also be seen from FIG. 3 that a hot water inlet 17 and an observation window 18 are simultaneously provided on the container cover 1 .

When the viscosity of the product is low, it is more appropriate to use a single helical cylindrical mixing reactor, because the equipment is relatively simple, the cost is low, and the amount of mixing at one time is also large.

And when the viscosity of the product is high, the part close to the wall of the reactor may be unevenly stirred when the single helical cylindrical mixing reactor is used for mixing, and the phenomenon of reaction dead angle may occur. At this time, it is more appropriate to use a double-helix conical mixing reactor, which is more advanced and will not cause dead ends, precipitation, layered segregation, etc. The cost of the equipment is high, and the amount of mixing at one time is also small.

The viscosity of the product can be determined according to the distance of transportation and the amount of dilution during use. Generally speaking, for local production and local use, it is better for the product to have a lower viscosity, because it only needs to be diluted slightly to apply. However, when the product is to be transported to a distant place for use, the thinner product is obviously not conducive to transportation. First, the transportation volume increases, and second, there are more protection measures during transportation. At this time, it is more suitable to produce products with higher viscosity, but when the product has higher viscosity, the workload of dilution will increase.

Because the utility model adopts a double-layer structure for the fixed container wall, a heating jacket is formed between the inner wall and the outer wall of the fixed container wall. Heating, heat preservation and cooling are performed, so it is beneficial to ensure the quality of the product.

Since there is a hot water inlet on the container cover, the predetermined hot water or corresponding solvent can be added to the mixed material in the container through the hot water inlet, which is convenient for controlling the viscosity of the product. There is an observation window on the top, so it is convenient to observe the mixing status of the mixed materials in the container.
