Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, reference numerals 1-12 are respectively shown as: the device comprises a spiral conveyor 1, a centrifugal device 2, a belt conveyor 3, an outer cylinder 4, an inner cylinder 5, a bearing 6, a driving gear 7, a drain pipe 8, a soil inlet 9, a soil outlet 10, a water outlet 11 and spiral blades 12.
Example (b): as shown in fig. 1, the centrifugal type muck separating device in the present embodiment is a centrifugal device 2, and the centrifugal device 2 is attached to a position of a muck discharge port of a screw conveyor 1, and is used for performing solid-liquid separation on muck conveyed by the screw conveyor 1, and a separated solid portion is conveyed by a belt conveyor 3, and muddy water containing small particles is collected and discharged by a muddy water pump.
Specifically, as shown in fig. 2, the centrifugal device 2 includes an outer cylinder 4 and an inner cylinder 5. Wherein, the outer cylinder 4 is fixed at the rear part of the screw conveyor 1 and is fixedly connected with the screw conveyor; the outer cylinder 4 mainly plays a role in fixing and sleeping. The inner cylinder 5 is fixed inside the outer cylinder 4 by two bearings 6 so that the inner cylinder 5 can be placed inside the outer cylinder 4. One side of the inner cylinder 5 is provided with a soil inlet 9, the soil inlet 9 is butted with a soil outlet of the screw conveyor 1, and the residue soil conveyed by the screw conveyor 1 can enter the inner cylinder 5 from the soil inlet 9.
The spiral fan blades 12 are arranged in the inner barrel 5, the spiral fan blades 12 are hollow without shafts, the fan blades are directly fixed on the inner wall of the inner barrel 5 and are provided with wear-resistant welds, and the spiral fan blades are prevented from being worn through after being used for a long time, so that the service life of the spiral fan blades 12 is ensured. In this embodiment, the spiral fan 12 also plays a role of conveying the muck, that is, the muck is subjected to solid-liquid separation under the action of centrifugal force, and at the same time, the separated solid part is gradually spirally propelled from the soil inlet 9 to the soil outlet 10 through the spiral fan 12 until the separated solid part falls on the belt conveyor 3 from the soil outlet 10 for normal transportation.
A water discharge hole is formed on the inner wall of the inner cylinder 5 at a position between the two bearings 6 for discharging water in the soil during rotation. The outer cylinder 4 and the inner cylinder 5 are coaxially arranged, a gap serving as a water collecting tank is reserved between the outer cylinder and the inner cylinder, and the gap is communicated with a drain hole formed in the inner cylinder 5. The outer cylinder 5 is provided with a water outlet 11. The water in the dregs can enter the water collecting tank between the outer cylinder 4 and the inner cylinder 5 from the water discharging hole on the inner cylinder 5 and then flows to the water outlet 11 from the water collecting tank to be discharged.
In this embodiment, since the outer cylinder 4 and the inner cylinder 5 are disposed in an inclined manner in accordance with the screw conveyor 1, the water outlet 11 is formed at the lowest position of the outer cylinder 5, so that the separated muddy water can flow out of the water outlet 11 by its own weight.
In this embodiment, a drain pipe 8 is connected to the water outlet 11, and a dredge pump is connected to the drain pipe 8 to pump the separated muddy water containing small particles into the sewage tank for centralized treatment.
As shown in fig. 2, a drive gear 7 is provided on the soil outlet 10 side of the inner cylinder 5, and the inner cylinder 5 is driven to rotate in the outer cylinder 4 by connecting the drive gear 7 to an externally connected motor. In order to mount the driving gear 7, the wall of the inner cylinder 4 should be properly extended to a part of the wall of the outer cylinder 5 to meet the mounting requirement of the driving gear 7.
In the embodiment, in specific implementation: the outer cylinder 4 and the screw conveyor 1 can be connected through a flange, and the joint should be tightly waterproof, for example, a rubber sealing strip is arranged at the joint of the outer cylinder and the screw conveyor to prevent water leakage, so that muddy water contained in the muck is prevented from flowing into the tunnel from the joint.
The bearing 6 should be a waterproof bearing to cope with the operational needs of the water-containing environment.
The centrifugal device 2 in this embodiment is used in cooperation with the screw conveyor 1 for the rear unearthed part, and when the screw conveyor for the lower unearthed part is used, the centrifugal device 2 can be subjected to adaptive structural modification according to the principle of this embodiment, so as to be applied to the screw conveyor for the lower unearthed part or the screw conveyor for other unearthed parts.
In order to secure the centrifuge 2 and maintain its structural stability during use (when the inner cylinder 5 is rotated), the outer cylinder 4 at the soil outlet 10 of the centrifuge 2 should also be connected in a fixed position.
An observation window can be provided on the wall of the outer cylinder 4 between the two bearings 6, through which the operator can observe the operation inside the centrifugal device 2 for corresponding operation or control.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
