Background technique

Horizontal centrifuge, using the high-speed rotating drum to generate centrifugal force to trap the solid particles in the suspension in the drum and automatically discharge them outside the machine under the action of force; at the same time, under the action of centrifugal force, the liquid in the suspension It is thrown out through the filter medium and the small holes of the drum, so as to achieve the purpose of liquid-solid separation and filtration.

The horizontal centrifuge on the market is just as the Chinese patent that notification number is CN203448190U discloses a kind of horizontal screw unloading settling centrifuge, and it comprises casing, drum, screw pushing device, and this drum is powered by drum. The device is driven to rotate, and the drum is provided with a liquid discharge port and a solid discharge port; the screw pushing device includes a hollow mandrel, the outer wall of the mandrel is provided with helical pusher blades, and the inner cavity of the mandrel is set There is a distribution accelerator, the distribution accelerator communicates with the outer space of the screw through the distribution hole, the distribution accelerator includes a connecting body arranged in the middle of the mandrel, the connecting body is provided with a distribution chamber, and the front end of the distribution chamber is provided with a feed port, the The side wall of the connecting body is provided with at least two distributing holes communicating with the distributing cavity, and the hole on the rotating downstream side of each distributing hole extends along an arc from inside to outside toward the rotating downstream side.

When the above-mentioned horizontal spiral unloading decanter centrifuge is applied to the existing market, the distance between the two ends of the casing is constant, and the length of the frustum of the cone is often longer, which makes the solid phase in the conical cylinder It is easy to cause blockage when the body position is too long, and when the blockage section is longer, the friction force will increase, which will cause the differential gauge to stop working.

Utility model content

The purpose of this utility model is to provide a special horizontal centrifuge for fermented liquid, which has the advantage of not changing the length of the original drum, so that the cone body is not easy to be blocked and stop working.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a special horizontal centrifuge for fermented liquid, including a drum and a mandrel, the drum includes a cylindrical cylinder and a conical cylinder connected to each other, the The mandrel includes a hollow cylinder and a round table pushing head, and a material distribution chamber communicated with the cylinder body is arranged inside the circular table pushing head, and a feed pipe is arranged on the said material distribution chamber, and the hollow cylinder and the round table pusher Spiral blades are arranged on the outside of the material head, and the two ends of the drum are respectively provided with a small end cap and a large end cap.

Further, a distributing cone for uniformly dispersing the liquid is provided at a position corresponding to the feeding pipe on the side away from the feeding pipe in the material distribution chamber.

By adopting the above technical scheme, the setting of the liquid separation cone can evenly disperse the liquid that is flushed in when the liquid in the feed pipe is quickly rushed in. On the one hand, it can quickly disperse the liquid into the material distribution chamber and flow into the cylinder. Inside the barrel; on the other hand, it can slow down the impact of the liquid on the inner wall of the material distribution chamber, so that the inner wall of the material distribution chamber is not easily deformed during long-term use.

Further, the side of the material distribution chamber connected to the liquid distribution cone is recessed away from the feed pipe to form a rectification groove, and the two sides of the rectification groove respectively overlap with the liquid separation cone and the side wall arc of the material distribution chamber.

By adopting the above-mentioned technical scheme, the rectifying groove set in the material distribution chamber can guide the liquid to the side wall of the material distribution chamber through the arc transition part after the liquid distribution cone disperses the liquid, so that the liquid flow direction in the material distribution chamber Not too messy, so it can flow more comfortably into the cylindrical barrel.

Further, the material distribution chamber communicates with the cylinder through a material distribution port, and there are at least two material distribution ports, and each of the material distribution ports is misaligned along the axis of the hollow cylinder.

By adopting the above-mentioned technical scheme, the material distributing port is dislocated in the material distributing chamber along the axial direction of the hollow cylinder, so that there is a position for liquid outlet on the side wall of the material distributing chamber, so that during the rotation process, the liquid in the material distributing chamber Liquid can be discharged at any position, which improves the efficiency of liquid discharge.

In summary, the utility model has the following beneficial effects:

The angle between the side of the circular table pushing head and the axis of the circular table pushing head is 35°, which reduces the stacking section of the circular table pushing head, thereby reducing the resistance to the rotation of the conical cylinder, making the conical cylinder less susceptible to blockage and stop working;

The setting of the splitter cone can slow down the impact force of the liquid and cooperate with the rectification groove to guide the water flow;

The dislocation setting of the material distribution port improves the liquid discharge efficiency.
