Description
Technical Field
The utility model relates to a horizontal spiral sedimentation centrifuge field especially relates to a rotary drum for horizontal spiral sedimentation centrifuge.
Background
The horizontal spiral sedimentation centrifuge is a machine which makes a solid-liquid mixture enter a rotary drum through a feeding pipe and a spiral discharge port, under the action of centrifugal force generated by high-speed rotation of a host, solid-phase particles with large specific gravity are deposited on the inner wall of the rotary drum, spiral blades which move relative to the rotary drum continuously scrape the solid-phase particles deposited on the inner wall of the rotary drum and push the solid-phase particles out of a slag discharge port at one end of the rotary drum, and separated clear liquid flows out of a liquid outlet at the other end of the rotary drum. However, in practical application, the solid-phase particles discharged from the slag discharge port flow out to a position between the rotary drum and the shell of the centrifuge, so that friction exists between the rotary drum and the shell of the centrifuge, and potential safety hazards are caused (the rotary drum has high rotating speed, and the potential explosion hazards are caused due to excessive friction).
As shown in fig. 1, which is a schematic partial cross-sectional view of a horizontal spiral sedimentation centrifuge in the prior art, in order to reduce outflow of solid phase particles, two outer baffles are additionally arranged on the inner wall of a centrifuge housing, the outer sides of the outer baffles are respectively located at two sides of a slag discharge port, the outer sides of the outer baffles are connected with the inner wall of the centrifuge housing, and a gap (which is a necessary space for the operation of a rotary drum) is left between the inner sides and the outer wall of the rotary drum. After the solid particles are discharged from the slag discharge hole, the solid particles can be thrown to the shell of the centrifuge between the two outer baffles under the action of centrifugal force, finally fall down and are discharged from the slag discharge hole of the centrifuge, but cannot flow out of the outer baffles.
Therefore, the increase of the outer baffle reduces the outflow of the solid-phase particles to a certain extent, but the effect does not reach the expected target because a gap still exists between the outer baffle and the rotary drum.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a rotary drum for horizontal spiral sedimentation centrifuge to prevent solid phase particle outflow.
In order to achieve the above purpose, the technical solution of the present invention is as follows:

Detailed Description
The present invention will be described in further detail with reference to examples.
The present embodiment provides a drum for a horizontal spiral sedimentation centrifuge, as shown in fig. 2 to 4, a drum 2 is installed in a centrifuge housing 1, the inner wall of the centrifuge housing 1 is provided with two outer baffles 4 respectively located at two sides of a slag discharge port 3 of the drum 2, the outer periphery of each outer baffle 4 is connected to the centrifuge housing 1, a gap 8 (the gap 8 is a necessary space for the operation of the drum 2) is left between the inner periphery and the outer wall of the drum 2, the drum 2 is provided with an inner annular baffle 5 located at the inner side of each outer baffle 4, the two inner annular baffles 5 are respectively located at two sides of the slag discharge port 3 of the drum 2, one end of each inner annular baffle 5 is connected to the outer wall of the drum 2, and the other end of each inner annular baffle 5 is provided with a gap 8 (the gap 8 is also a necessary space for the operation of the.
Through the cooperation of interior outer baffle, further to the solid particle outflow production block, for the outflow of further stopping solid particle, ring baffle 5 is equipped with blade 6 on the face that leans on one side of outer baffle 4 including this embodiment, and when rotary drum 2 was rotatory, blade 6 on the one hand can block the solid particle outflow, and on the other hand can produce the air current that makes progress, further blocks the solid particle outflow, has promoted horizontal spiral sedimentation centrifuge's security greatly.
Although the slag discharge port 3 of the rotary drum 2 is used for discharging the solid particles after phase separation, the slag drying rate of the solid particles is still high, in the embodiment, the side wall of the rotary drum 2 close to the slag discharge port 3 is provided with the mounting hole communicated with the inner cavity of the rotary drum 2, the mounting hole is provided with the filter screen 7, liquid can pass through the filter screen 7, but the solid particles can be blocked by the filter screen 7. When the centrifuge is running, the solid particles are pushed to the slag discharge port 3 by the screw conveyor (at this time, because the liquid in the solid particles is also separated by centrifugal force during the rotation process), when the solid particles pass through the filter screen 7, the separated liquid is thrown out of the filter screen 7, and the solid particles are blocked by the filter screen 7. It can be seen that the provision of the sieve 7 improves the slag drying rate of the discharged solid particles.
The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
