Abstract
The utility model discloses a feeding and discharging device for a biogas digester. The feeding and discharging device comprises a feeding port, a discharging port and a motor. A cavity of a volute body is provided with a vortex generator capable of rotating. The vortex generator is installed on a shaft and connected with the motor through a coupler and is sealed with a stuffing box body. The front end of the volute body is provided with a feeding end cap. The utility model provides the device for pump drainage of biogas slurry and biogas residue and with reasonable structure; vortex is formed in the volute body during rotation of the vortex generator disposed in the vortex generation cavity in the rear portion of the volute body and comprises run-through flow and circulating flow, and the liquid flow mode is greatly different from that of a conventional sewage pump; accordingly, with the vortex generator and through damage of substances, the device is capable of pumping solid particles with the diameters less than 65mm and the biogas slurry and the biogas residue containing fibrous materials and pumping the biogas slurry and the biogas residue with the gas content not greater than 15%; and the equipment can run smoothly without blockage, so that the maintenance frequency is furthest reduced and working efficiency for feeding and discharging of the biogas slurry and the biogas residue is improved.
Description
Technical field:
The utility model relates to the feeder in a kind of biomass pool, and the nothing that is specially adapted to liquid natural pond, the natural pond slag in big-and-middle-sized engineering is stopped up pump drainage.
Background technique:
At present when the cleaning biomass pool, mostly use centrifugal sewage pump to carry out pump drainage, because of after the natural pond slag in biomass pool fermented, need to extract out and add virgin material in biomass pool, fermentation material mostly is animal wastes (as: Swine, bovine, chicken class etc.) various straws (as: wheat straw, corn stalk etc.) and rubbish mud etc., therefore after above fermentation material has fermented, it contains a large amount of long fibre things, and a small amount of not fermentation material of fermentation finished thoroughly1, can continue to produce a small amount of biogas.In existing technology, fiber can produce the centrifugal sewage pump impeller in work and be wound around and stop up runner, and pump drainage is had some setbacks, and because liquid natural pond, natural pond slag still can continue to produce a small amount of biogas, centrifugal sewage pump can lose pumping capacity because of air-pocket obstruction.
Summary of the invention:
Task of the present utility model is to propose a kind of natural pond slag that not only can inhale the fibre-bearing thing, and can also aspirate concentration and be not more than 15% liquid natural pond, natural pond slag, equipment is run well, can not lose charging/discharging device in a kind of biomass pool of pumping capacity because of air-pocket obstruction.
Task of the present utility model is completed like this, feeder in a kind of biomass pool, it comprises charging and discharging mouth and motor, it is characterized in that: a rotatable eddy generator is housed in the cavity of volute body, described eddy generator is arranged on axle and is connected with motor by coupling, with the stuffing box body sealing, described volute body front end is equipped with the charging end cap.The spindle nose of described axle is fixed with nut, and the other end of axle is connected with motor by coupling, described axle by axle sleeve by bearing and bearing bracket and compress with bearing (ball) cover.Described charging end cap is disc, and the center is circular material feeding mouth, and described charging end cap one end is connected with supply pipe by flange, and its other end is connected with volute body by flange, and bolt connecting hole is arranged on flange.Described volute body is spirality, and inside is hollow cavity, and it is disc that eddy generator is housed in it, and blade is housed on it, and spiral outlet is provided with rising pipe.Described stuffing box body is disc, along the flange hole that is connected with bearing bracket with volute body is arranged on the disk circumference face.
the utlity model has following effect: the utility model provides the device of liquid natural pond, a pump drainage natural pond slag rational in infrastructure, it is by the eddy generator of the whirlpool generation intracavitary unit at volute body rear, form whirlpool during the eddy generator rotation in volute body, the stream of perforation and circular flow are arranged in whirlpool, flow of fluid form and traditional wastewater pump have very big difference, by the destruction to material, not only can aspirate the following solid particle of φ 65mm and liquid natural pond, the natural pond slag of fibre-bearing thing, and can also aspirate air content and be not more than 15% liquid natural pond, natural pond slag, do not stop up because of unobstructed in equipment operation, so can reduce to greatest extent the maintenance number of times, thereby improve the working efficiency of liquid natural pond, natural pond slag feeding and discharging.
Description of drawings:
Fig. 1 is structure cut-away view of the present utility model.
Drawing explanation: 1, charging end cap, 2, volute body, 3, eddy generator, 4, stuffing box body, 5, rubber hose coupling, 6, axle sleeve, 7, bearing (ball) cover, 8, axle, 9, bearing bracket, 10, bearing, 11, pump nozzle, 12, water retaining ring, 13, stuffing hole, 14, nut, 15, coupling.
Embodiment:
describe embodiment in detail in conjunction with above accompanying drawing, as shown in Figure 1, a rotatable eddy generator 3 is housed in the cavity of volute body 2, on described eddy generator installation shaft 8, spindle nose is fixing with nut 14, the other end of axle is connected with motor by coupling 15, take motor as the power High Rotation Speed, be sealed into filler or mechanical seal, therefore install stuffing box body 4 additional, described axle 8 passes through bearing 10 and bearing bracket 9 by axle sleeve 6, and compress with bearing (ball) cover 7, make the bearing can't play, for guaranteeing that bearing 10 runs well for a long time, be equipped with pump nozzle 11 on bearing bracket, can regularly inject maintenance to bearing by pump nozzle, bearing bracket 9 is the base angle design of whole band, structural strength is high, good stability, vibratory output is little, described bearing bracket 9, stuffing box body 4 and volute body pass through flange connect, the volute body front end is equipped with charging end cap 1, this design is for the ease of checking the volute body internal state and being convenient for changing eddy generator, described charging end cap is disc, the center is circular material feeding mouth, described charging end cap one end is connected with supply pipe by flange, its the other end is connected with volute body by flange, bolt connecting hole is arranged on flange.Described volute body is spirality, inside is hollow cavity, spiral outlet is provided with rising pipe, it is disc that eddy generator is housed in it, blade is housed on it, described stuffing box body is disc, along the flange hole that is connected with bearing bracket with volute body is arranged on the disk circumference face, the center is to fill out charging hole 13, and there is small through hole the stuffing hole back, is used for axle and passes through, stuffing hole one side had the water aperture, rubber hose coupling 5 is housed on it, and substantially horizontal arrow shown in Figure 1 is material feeding mouth, is depicted as discharge port with material feeding mouth Vertical direction arrow.
During work, by 8 rotations of motor drives axle, the eddy generator 3 that drives 2 li of volute bodies when axle rotates runs up, drive liquid natural pond, natural pond slag by the blade on it and form whirlpool in volute body, entering the discharge port collision by material feeding mouth throws away, not directly by eddy generator, volute body in do not stop up gentle block up therefore do not exist due to taking out material, form real without stopping up pump drainage.Can produce pressure during due to the inherent work of volute body, sewage can along between axle sleeve and stuffing hole to outward leakage wearing and tearing axle sleeve, in order to prevent that the problems referred to above from producing, be processed with on stuffing box body 4 and expose the water hole, and rubber hose coupling 5 is housed, have clear water to inject the generation that effectively solves leakage, wear problem, between axle sleeve 6 and bearing (ball) cover 7, water retaining ring 12 is housed, effectively anti-sealing enters infringement bearing in bearing chamber.
