The feeding structure includes a distributor 6-3 which is arranged between the upper cylinder 6-1 and the lower cylinder 6-2 of the evaporator cylinder 1 and is sealed and fixed.

Specifically, the first connection flange 6-11 at the bottom of the upper cylinder 6-1 and the second connection flange 6-21 at the top of the lower cylinder 6-2 are used for the upper and lower limit fixing of the distributor 6-3, while The edge of the distributor 6-3 is equally divided with connecting holes 6-38, and the connecting bolts 6-5 pass through the connecting holes 6-38 to connect the distributor 6-3 with the first connecting flange 6-11 and the second connecting flange 6-21 fixed.

In the discharge setting, in order to ensure that the discharge can directly act on the cylinder wall, the edge of the discharge port 6-36 is flush with the inner walls of the upper cylinder body 6-1 and the lower cylinder body 6-2, that is, the outer side of the overflow weir set in the ring The end is flush with the inner wall of the cylinder.

The feeding port 6-31 is connected with the feeding inner outlet 6-37 arranged in the feeding groove 6-33, so that the feeding material can enter the feeding groove and then discharge through the overflow weir.

It is worth noting that there are overflow gaps evenly distributed on the overflow weir, and the overflow gaps are tooth-shaped overflow holes.

In terms of its working mechanism, the distributor is independent of the evaporator cylinder and is assembled on the upper part of the evaporator cylinder. The material enters the internal feed tank through the feed port, and then flows out slowly on the overflow weir, and is mounted on the inner wall to flow to the Cylinder, the scraper in the evaporator cylinder is thinned.

In the setting of the driving structure, the driving structure 2 includes a motor 21 , a driving cavity 22 , a coupling 23 and a single-end mechanical seal 24 .

The motor flange is fixed on the top of the drive cavity 22 and acts on the coupling 23 . The bottom of the drive cavity 22 is fixed with the upper flange of the evaporator cylinder 1 , and the coupling 23 is fixed with the scraper cage structure 3 .

In the setting of the scraper cage, the scraper cage structure includes a central rotating shaft 3-1 and an upper chuck 3-11 and a lower chuck 3-12 fixed on the upper and lower sides of the central rotating shaft 3-1.

The upper chuck 3-11 and the lower chuck 3-12 are hollow disc structures, and at least three scraper fixing shafts 3-3 are arranged between them, in this embodiment, there are four, and at the periphery Divide the upper chuck 3-11 and the lower chuck 3-12 equally.

The scraper fixing shaft 3-3 is overlapped with a plurality of hollow cylindrical scrapers 3-4, and there is an offset between the cylindrical scraper 3-4 and the scraper fixing shaft 3-3. The distance between the cylindrical scraper 3-4 and the upper chuck 3-11 is 2-5mm, so that the scraper can self-adjust during the working process.

In addition, the edge position of the cylindrical scraper 3-4 protrudes from the upper chuck 3-11 and the lower chuck 3-12.

At the same time, a defoamer 3-5 is also provided on the upper side of the upper chuck 3-11 on the central rotating shaft.

Specifically, the defoamer 3-5 is a symmetrical paddle structure, and the paddles are uniformly distributed with conical through holes 3-51.

The central rotating shaft rotates under the action of the motor, that is, the motor drives the coupling, thereby driving the central rotating shaft to rotate. Specifically, the central rotating shaft is limited by the bearing on the lower head on the lower side, so the cylindrical scraper can move up and down in series. Centrifugal shaking, the material flows into the evaporator cylinder from the feed structure by means of overflow, and is diluted, and at the same time, under the action of the water cavity, heat exchange and evaporation.

Specifically, the material enters the cylinder of the evaporator from between the scraper on the lower side of the defoamer and the cylinder wall. When the evaporator is working, the cylinder is in a vacuum state due to the action of the vacuum pump. After heating in a vacuum environment, the solvent is prone to surface tension expansion, which is similar to blowing soap bubbles to generate foam.

The foam will carry a part of the raw material and escape from the vacuum pipe, causing waste. At the same time, the foam will accumulate in the cylinder, causing the material to fall slowly. At this time, under the action of the defoamer, the foam will be removed from the large hole side of the conical hole. Scraped into the conical hole, and then extruded from the small hole of the conical bottom, the foam is circulated and dispersed here, and it will be broken and fall.

In this scheme, the diameter, length and weight of the cylindrical scraper are determined according to the specifications of the evaporator, the evaporation area, and the diameter of the cylinder. Generally, it is determined according to the material. The more viscous the material, the longer the scraper and the heavier the weight.

The scraper changes the weight of the scraper by changing the wall thickness and length. In order not to affect the efficiency of the scraper, if the wall thickness and length change, the rotating diameter of the scraper shaft should also be changed.

Generally speaking, the scraper is heavier and longer, and the effect will be better.

Moreover, the advantage of the segmented scraper is that the distance between the scraper of each section and the interior of the cylinder can be adjusted by itself.

For example, the material on the inner wall of a certain section of the cylinder is thicker due to the residence time and viscosity, so when the scraper in this section is working, the natural distance from the cylinder wall is larger.

In the same way, if the material in other parts of the cylinder wall is very thin, then because of the centrifugal force, the scraper will naturally be pressed against the cylinder wall, and the spacing will shrink by itself, so that each section of the scraper can be adjusted according to the thickness of the material. Adjust the distance between itself and the cylinder wall, as much as possible to press the centrifugal force generated by the rotation of the material through the central axis to the cylinder wall thinner to increase the evaporation efficiency.

To sum up, this scheme adopts the mechanism of cyclic bacterial preparation to overcome the problem of insufficient bacterial preparation leading to larger particle size. It also adopts a new type of evaporation, with buffer preheating to ensure the evaporation effect, and at the same time, multiple filtration before the finished product. process, product safety is high.

Through the setting of the distributor, the evaporator uses the overflow method to realize the uniform feeding of the entire cylinder wall, and the feeding is continuous and uniform, which is convenient for the subsequent thinning of the scraper, and ensures that the separation effect of the evaporator is stable and efficient.

At the same time, the connection of the distributor is convenient and fast, with high stability and good sealing performance, which can ensure that the vacuum state in the evaporation cylinder is not affected.

The scraper cage structure adopts a segmented scraper structure, which moves up and down and centrifugally swings, so that each section of scraper can self-adjust the distance from the cylinder wall according to the thickness of the material. On the cylinder wall, the evaporation efficiency is increased.

What's more, the defoamer breaks the foam, avoids the slow decline of the material due to the accumulation of the foam, and avoids the waste of raw materials.
