Abstract

The invention relates to a vortex air injection and mud absorbing pump. A mud feeding pipe is designed on a mud absorbing pump body. A mud shovel is fixed on the mud feeding pipe, and an air feeding pipe and an air discharging pipe are fixed at the upper end of the mud absorbing pump body. A baffle and a mud discharging pipe are fixed at the position in the mud absorbing pump body corresponding to the mud feeding pipe, and a vortex chamber is designed on the mud discharging pipe. The vortex chamber comprises a closed cavity welded outside the mud discharging pipe and a sprayer fixed at the position of the mud discharging pipe in the cavity. The cavity is connected with one end of the air discharging pipe, and a mud discharging valve is arranged in the mud discharging pipe. The baffle is V-shaped, one end of the baffle is welded on the inner wall of the mud absorbing pump body, the other end of the baffle is inclined, the distance between the lowest end of the baffle and the inner wall of the mud absorbing pump body is 10cm, and the sprayer is arranged inclined in 30 degrees. High pressure air proceeds in vortex shape in the vortex chamber, and the mud discharging pipe generates absorbing force to absorb mud at the bottom of the pump body. The working principle is that injection of the high pressure air is utilized to achieve absorbing and discharging of the mud absorbing pump body. The pump has the advantages of being simple in structure, convenient to maintain, environment-friendly, high in efficiency, energy-saving and low in cost.

Technical field

The invention belongs to dredge pump, the eddy spray aspiration dredge pump that particularly a kind of feature of environmental protection is good, energy-efficient.

Background technique

At present, be used for dredging and dredge and the pump of managing conveying, mostly be greatly the centrifugal pump of wheel rotation, centrifugal pump impeller rotates directly and connects motor, internal-combustion engine or oil hydraulic motor by axle, consumes the energy, serious wear, and the feature of environmental protection is poor, and cost is high.

Summary of the invention

The present invention provides a kind of feature of environmental protection good, energy-efficient eddy spray aspiration dredge pump for solving the problem that exists in the known technology.

The technological scheme that the present invention takes for the problem that exists in the solution known technology is: it comprises the dredge pump pump housing, advance the mud pipe, sludge drainage pipe, mud shovel and turnover, tracheae, it is characterized in that: the bottom of the dredge pump pump housing is designed with is with the valvular mud pipe that advances, an end that advances the mud pipe gos deep in the dredge pump pump housing, the other end is fixed with mud shovel, the upper end of the dredge pump pump housing be fixed with into, steam outlet pipe and steam outlet pipe, in the dredge pump pump housing with enter mud pipe relative position place and be fixed with baffle plate and sludge drainage pipe, be designed with the vortex chamber on the sludge drainage pipe, the vortex chamber comprises the fixing nozzle of box-shaped cavity and the sludge drainage pipe place in the cavity of the sealing of sludge drainage pipe outside welding, cavity is connected with an end of steam outlet pipe, and described sludge drainage pipe is interior with soil discharging valve.

The present invention can also adopt following technological scheme:

Described baffle plate 7 is the V font one end dredge pump pump housing 1 inwall welding, the other end be skewed its be 10cm apart from the dredge pump pump housing 1 inwall bottom;

Described nozzle be arranged on sludge drainage pipe around and be mutually 90 ° and locate, the every row of totally four rows is each 4-6, the inwall of nozzle and sludge drainage pipe is 30 ° of oblique arrangement, simultaneously, the tangent line of nozzle and sludge drainage pipe transverse section also is 30 ° of inclinations.

Advantage and good effect that the present invention has are: simple in structure, be convenient to safeguard, because of the spray and suction mud and the spoil disposal of penetrating to realize the dredge pump pump housing 1 by high-pressure air, so the feature of environmental protection is good, energy-efficient and cost is low.

Embodiment

For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows, see also Fig. 1-Fig. 3.

Such as Fig. 1-shown in Figure 3: the bottom of the dredge pump pump housing 1 is designed with advances mud pipe 3 with valve 2, an end that advances mud pipe 3 gos deep in the dredge pump pump housing 1, the other end is fixed with mud shovel 4, the upper end of the dredge pump pump housing 1 be fixed with into, steam outlet pipe 5 and steam outlet pipe 6, in the dredge pump pump housing 1 with enter mud pipe 3 relative position places and be fixed with baffle plate 7 and sludge drainage pipe 8, be connected with vortex chamber 9 by flange on the sludge drainage pipe 8, vortex chamber 9 comprises the box-shaped cavity 10 of the sealing that weld sludge drainage pipe 8 outsides and the fixing nozzle 11 in sludge drainage pipe 8 places in the cavity 10, described nozzle 11 be arranged on sludge drainage pipe 8 around and be mutually 90 ° and locate, the every row of totally four rows is each 4-6, nozzle 11 is 30 ° of oblique arrangement with the inwall of sludge drainage pipe 8, simultaneously, nozzle 11 also is 30 ° of inclinations with the tangent line of sludge drainage pipe 8 transverse section; Described cavity 10 is connected with an end of steam outlet pipe 6; In the described sludge drainage pipe 8 with soil discharging valve 12; Described baffle plate 7 is the V font one end dredge pump pump housing 1 inwall welding, the other end be skewed its be 10cm apart from the dredge pump pump housing 1 inwall bottom.

During operation, the dredge pump pump housing 1 advances with mud shovel 4,5 venting of turnover tracheae, advance mud pipe 3 inspiration silts, when the dredge pump pump housing 1 is full of 2/3, turnover tracheae 5 ejection high-pressure airs, but it does not reach the bottom of the dredge pump pump housing 1, at this moment, part high-pressure air is by steam outlet pipe 6, cavity 10 and nozzle 11 enter vortex chamber 9, because the installation of nozzle 11 is 30 ° of oblique arrangement, so the high-pressure air that enters 9 is the eddy current shape and advances in the vortex chamber, makes the sludge drainage pipe 8 interior generation suction that are connected with the dredge pump pump housing 1, and with the gap location sucking-off by baffle plate 7 and the dredge pump pump housing 1 inwall of the silt of the dredge pump pump housing 1 lower end, at this moment, silt boosts the valve ball in the soil discharging valve 12 and discharges from the outlet of sludge drainage pipe 8; In a word, its working principle mainly is by the spray of high-pressure air and penetrates, is similar to vein and propels and suction mud and the spoil disposal of drawing blood to realize the dredge pump pump housing 1.

Its advantage is: simple in structure, be convenient to safeguard, because of the spray and suction mud and the spoil disposal of penetrating to realize the dredge pump pump housing 1 by high-pressure air, so the feature of environmental protection is good, energy-efficient and cost is low.

Above-described embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technological scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
