Abstract
Description
Technical Field
[0001] The utility model relates to a separation mechanism, in particular to a high-efficiency separation mechanism for a horizontal scroll centrifuge. Background Art
[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. With the continuous development of industry, centrifuges are widely used in chemical industry, petroleum, food, pharmaceutical, mineral processing, coal, water treatment, shipbuilding and other fields.
[0003] When the horizontal scroll centrifuge is working, it will generate a high-intensity rotational speed. Through the differential, the drum and the screw installed inside the drum rotate in the same direction at different speeds. The screw drives the screw blades to rotate and take away the solid phase deposited on the inner wall of the drum, so as to achieve the state of solid-liquid separation. There are the following defects in the existing ones. Since the residence time of the material in the drum of the horizontal scroll centrifuge is not long, the solid phase and the liquid phase cannot be completely separated during rotation, so that the final liquid phase will still contain solid phase impurity components, and the effective separation effect cannot be achieved. Summary of the Utility Model
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a high-efficiency separation mechanism for a horizontal scroll centrifuge, which effectively solves the problem that in the existing horizontal scroll centrifuge, due to the short residence time of the material in the drum, the solid phase and the liquid phase cannot be completely separated during rotation, so that the final liquid phase still contains solid phase impurity components and the effective separation effect cannot be achieved.
[0005] To achieve the above object, the utility model provides the following technical solutions: The utility model includes a housing arranged outside, legs arranged at the bottom of the housing, a drum arranged inside the housing, a squirrel-cage rotating cylinder installed inside the housing, a differential installed on one side of the squirrel-cage rotating cylinder, a conical-section screw installed on the other side of the squirrel-cage rotating cylinder, and a straight-section screw installed at one end of the conical-section screw. It also includes screw blades, fan-shaped inclined plates, a feed pipe, auxiliary components, a discharge port, a liquid discharge port, a support, a pneumatic hammer and rubber balls. The middle of the straight-section screw is provided with a feed pipe, an auxiliary component is installed on one side of the housing, a discharge port is arranged at the bottom of one end of the housing corresponding to the position of the squirrel-cage rotating cylinder, and a liquid discharge port is arranged at the bottom of the other end of the housing;
[0006] The auxiliary component includes a storage tank, a liquid extraction pipe, a delivery pump, a delivery pipe, a drain pipe and a drain valve. The storage tank is connected to the liquid discharge port. A liquid extraction pipe is installed inside the storage tank. The top of the liquid extraction pipe penetrates through the storage tank and installs a delivery pump. The liquid outlet of the delivery pump is connected to a delivery pipe communicated with the feed pipe. A drain pipe is arranged at the bottom end of one side of the storage tank.
[0007] Preferably, a number of helical blades are provided on the surfaces of the conical-section helix and the straight-section helix, and a sector-shaped inclined plate is provided on one side of the helical blades on the straight-section helix.

[0012] Beneficial effects: When the present utility model is in use, the separated liquid discharged through the liquid discharge port enters the interior of the storage tank. After storing a certain amount, the transfer pump operates. The transfer pump operates to transport the separated liquid back to the feed pipe through the liquid extraction pipe and the transfer pipe, and then enters the horizontal screw centrifuge again through the feed pipe for centrifugal separation, improving the separation degree of the horizontal screw centrifuge. When the material is separated more thoroughly, the drain valve installed on the drain pipe is opened, and the liquid can be discharged through the drain pipe. The pneumatic hammer extends out at intervals, and the rubber ball at one end of the pneumatic hammer knocks on the discharge port, improving the discharging efficiency of the discharge port. The structure of the present utility model is novel and ingeniously conceived, facilitating a more thorough separation operation of the material, being beneficial to the separation and use of the horizontal screw centrifuge, and being simple and convenient to operate.
