Abstract
The utility model relates to a horizontal self-discharging centrifugal dehydrator, belonging to the technical field of coal preparation equipment. The technical problem to be solved is to provide a horizontal self-discharging centrifugal dehydrator which is applicable to middling coal dehydration and has simple structure, high reliability and little energy consumption. The scheme thereof is as follows: the horizontal self-discharging centrifugal dehydrator comprises a rack, a shell, a sieve basket, a feeding pipe, a main shaft, a box body and a support, wherein the sieve basket is a cylinder shaped like a cone frustum, the cylinder is transversely and horizontally arranged, the small end of the cylinder shaped like a cone frustum is connected with the main shaft by the sieve basket seat and a cone sleeve; and the semi-cone angle of the cylinder shaped like a cone frustum is 15 degrees to 25 degrees. The horizontal self-discharging centrifugal dehydrator with the structure does not needa vibrating system, also does not discharge materials by utilizing the difference of rotation speed between a scraper and the sieve basket, and completes automatic material discharging by horizontalarrangement of the sieve basket designed with a large coning angle. The horizontal self-discharging centrifugal dehydrator has the advantages of having simple structure, stable running, power conservation for each ton of coal, high reliability, few easily-damaged parts and convenient maintenance and overhaul and reducing use cost of the centrifugal machine and the like, and is applicable to beingused as the centrifugal machine for middling coal dehydration.
Description
Technical field
The utility model relates to a kind of the horizontal from the discharging centrifugal dehydrator of middle coal dewatering that be applicable to, belongs to the cleaning unit technical field.
Background technology
At present, the leading type of the centrifugal dehydrator that a lot of coal preparation plants use is vertical centrifuge with cutter discharge of solid and horizontal vibrating centrifuge, and the centrifuge of these two kinds of types is used for the cleaned coal dehydration mostly, and is all undesirable aspect middle coal dewatering.Obviously shorten the service life of consumable accessorys such as the basket of vertical centrifuge with cutter discharge of solid, scraper, bell cover, and maintenance is frequent, has increased equipment maintenance cost, has improved production cost.Horizontal centrifuge is compared with the vertical helical centrifuge with cutter discharge of solid to have material size and increases to advantages such as the degradation rate of 50mm, few easy workout part, coal is low, the processed in units amount is big, easy to maintenance, simple in structure, floor space is few, can simplify the technological process of coal preparation plant greatly, most coal preparation plants are adopting horizontal vibrating centrifuge aspect the middle coal dewatering more.But the vibrational system more complicated of horizontal vibrating centrifuge is had relatively high expectations to the field service personnel level, as safeguards that more serious fault appears in the untimely centrifuge that just may cause, and what influence was produced carries out smoothly, and the price comparison costliness.
Summary of the invention
Technical problem to be solved in the utility model provide coal dewatering in a kind of being applicable to simple in structure, reliability is high, power consumption is few horizontal from the discharging centrifugal dehydrator.
The technical scheme that solves the problems of the technologies described above is:
A kind of horizontal from the discharging centrifugal dehydrator, comprise frame, casing, basket, feeding pipe, main shaft, casing, bearing, main motor, belt pulley in the composition, its improvement is: basket is the truncated cone cylindrical shell, the cylindrical shell transverse horizontal is placed, the small end of frustum of a cone cylindrical shell is connected with main shaft with tapered sleeve by the basket seat, and the semi-cone angle angle of frustum of a cone cylindrical shell is 15 °～25 °.
Above-mentioned horizontal from the discharging centrifugal dehydrator, the ring-shaped rubber spring is installed on the sleeve of tank ends, the ring-shaped rubber spring is fixed on the bearing, and bearing connects with frame by bolt.
Adopt the horizontal of this structure from the discharging centrifugal dehydrator, need not vibrational system, neither be by the speed discrepancy discharging between scraper and basket, but finish from discharging by the horizontal placement of the basket that is designed to big cone angle, the ring-shaped rubber spring can weaken the percussion of pan feeding to centrifuge.The utlity model has simple in structure, operate steadily, ton coal power consumptive province, reliability height, few easy workout part, Maintenance and Repair are convenient, the advantages such as use cost that reduced centrifuge, suitable as in the centrifuge of coal dewatering use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a basket structure zoomed-in view among Fig. 1.
Number in the figure is respectively: isolation spring 1, frame 2, small belt pulley 3, main shaft 4, big belt pulley 5, bearing 6, casing 7, ring-shaped rubber spring 8, basket seat 9, feeding pipe 10, lid door 11, basket 12, casing 13, delivery port 14
The specific embodiment:
Fig. 1 shows, the utility model with horizontal vibrating centrifuge something in common of the prior art is: organic frame 2, casing 13, basket 12, feeding pipe 10, main shaft 4, casing 7, bearing 6 etc. in the formation, basket 12 by main motor through belt pulley 5 and main shaft 4 driven rotary.
Main improvement of the present utility model is: need not vibrational system, neither be by the speed discrepancy discharging between scraper and basket, but finish from discharging by transmission system and basket design, adopt following structure for this reason.
The utlity model has following characteristics:
1. adopt that horizontal to be designed into the material granularity scope big, it is little to take up room, and treating capacity is big, can greatly simplify coal preparation plant Technological process.
2. realize self-discharging by transmission system and basket design, the friction system, basket only has the rotation around axle not have Axial vibration, ring-shaped rubber spring can weaken pan feeding to the percussion of centrifuge, and is simple in structure, operates steadily the ton coal The reliability of centrifuge has been improved in the power consumptive province, and Maintenance and Repair are convenient.
3. few easy workout part has reduced the use cost of centrifuge, cost performance height.
The centrifuge of coal dewatering uses in the suitable conduct of the utility model.
