Abstract

An impeller-less powerful sludge pump, comprising a pump body, an air distribution pack, air inlet/outlet flanges, upper and lower fixing boards, and a plurality of tapered air pipes between the upper and lower fixing boards; wherein, the upper and lower fixing boards are in circular shape, a plurality of tapered air pipes are arranged between a plurality of through holes near the outer circumference of the fixing board, and a plurality of cylindrical powerful pressurization rings separated into heterotypic air ducts by a plurality of inclined plates on the inner circumference of the upper and lower circular fixing boards; the air inlets of the powerful pressurization rings and air pipes communicate with the sealed air distribution pack on the pump wall; since the air pipes on the bottom of the sludge pump are in tapered structure, a plurality of heterotypic air ducts are arranged in the powerful pressurization rings, and no impeller is employed in the pump body, the air blasted by an external blast fan can form strong swirling eddy similar to cyclone in the sludge pump, and the airflow also has powerful suction force; therefore, slurry obstruction substances can be sucked into the sludge pump and blasted out with the swirling eddy. The pump is suitable for dredging underground sewage pipelines, river courses, and trenches, etc.

Description

A kind of impeller-less powerful sludge pump

[technical field]

The present invention relates to the equipment of a kind of city underground sewer and river dredging, blowdown, is a kind of impeller-less powerful sludge pump specifically.

[background technique]

Irrigation river course around the cities and towns, the underground sewer in the cities and towns often because of silt and insoluble substance deposition, stop up, and cause the riverbed to raise, and sewage outflow brings many troubles for the cities and towns environmental sanitation department of various places.Original in order to overcome existing waste removal equipment, the present situation that falls behind, and the dirt-absorbing ability of some antiblocking wind-force waste removal equipment is little, the defective that blowdown is of poor benefits, the applicant was on August 12nd, 2003, once applied for that an application number was 03124743.1, name is called a kind of patent of vortex type dirt sucking device, it is to form at the distribution bag that is equipped with on the dirt inlet of conical dirt sucking tube bottom by on many airducts that weld between two circular fixed plates and two fixed plates up and down and the airduct intake grill, external blower on distribution bag intake grill, make the air that blasts behind many taper airducts, form strong whirlwind, blow out from the airduct mouth, all backward, corrupt and reactionary things in the sewerage and high speed rotating air-flow are ejected into specified position together.In practice, find that the ejecting force of this dirt sucking device is also not really strong, the rotation wind-force of formation is not ideal enough, and it is motionless that some insoluble substance in all backward, corrupt and reactionary things such as brick, heavier object etc. are inhaled, and influences the working efficiency of this dirt sucking device.

[summary of the invention]

In order to overcome the above-mentioned defective of existing vortex type jet dirt sucking device, the invention provides a kind of impeller-less powerful sludge pump, to strengthen the rotation wind-force of dirt sucking device, improve pollution discharge capability and filth-discharging effect.

For solving its technical problem, the technical solution adopted in the present invention is: design includes the pump housing, the distribution bag, the exhaust outlet flange, the intake grill flange, on, on bottom plate reaches, many tapered airducts between bottom plate, it is characterized in that: the described bottom plate of going up is circular shape, last, be provided with many tapered airducts near between a plurality of through holes of excircle on the bottom plate, last, the inner circumference of following circular shape fixed plate is provided with the powerful compression ring of cylinder type that is separated into many special-shaped air channels by the polylith swash plate, the intake grill of this brute force compression ring and each airduct all be located at soil pick-up pump housing wall on the airproof gas distribution bag communicate.

The powerful compression ring of described cylinder type is the cylindrical body that inside and outside double-deck body wall is arranged, and is provided with polylith and the swash plate that angle is radially arranged between cylindrical inside and outside double-deck body wall, and the length of swash plate and cylindrical equal in length make and form many special-shaped air channels between the double-deck body wall.

The central through bore of described powerful compression ring is a sewage routeway, and the dirt inlet of sewage routeway and intake grill are isolated, and be not connected, and the water outlet of limber communicates with the front end of air outlet in the soil pick-up pump of each airduct and powerful compression ring.

During work, blower and ajutage thereof that intake grill flanged joint and other of distribution bag join link to each other, the wind that blower is sent, behind distribution bag and many tapered airducts and special-shaped air channel, in the soil pick-up pump, form powerful swirling eddy, obturator in the underground limber is washed away, breaks up, is washed into sposh and suck, be ejected into specified position, such as on the refuse collection vehicle or contain in the dirty pond through the air-out dirt-discherging outlet of soil pick-up pump upper end and external blowdown flexible pipe from the horn mouth of soil pick-up pump lower end.

The invention has the beneficial effects as follows: 1. because the tapered structure of many airducts of soil pick-up pump bottom, add many special-shaped air channels in the powerful compression ring, and this structure is by designing in advance, the shape of bottom plate and airduct thereof and determining positions, both be convenient to manufacturing, can guarantee the required precision that designs again, therefore the air of compressing into when blower can form the powerful swirling eddy of similar hurricane at the soil pick-up pump, this air-flow has powerful impact force to the obturator in the underground sewage pipe, no matter be brick, hard thing can both wash away, break up, and be washed into sposh, this air-flow also has powerful adsorption force, the obturator that can will be washed into the sposh shape sucks the soil pick-up pump, and is ejected into specified position together with swirling eddy.2. because of the soil pick-up pump does not have impeller, water channel is cavity entirely, does not have obstacle, so insoluble substance in drainage pipeline and the river course, can not be tangled as clothes, plastic bag, braided bag etc., fault can not taken place to twine and block, therefore can be remained filth-discharging effect efficiently.3. simple, the processing ease of this soil pick-up pump structure, user cost is low, and is of many uses; can not only dredge the cities and towns underground sewer, but also dredging river, irrigation canals and ditches, one-object-many-purposes; labor intensity in the time of can alleviating cities and towns sanitationman's dredging sewer helps again preserving the ecological environment.

[description of drawings]

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a form structure schematic isometric of the present invention.
