Abstract

The utility model discloses a kind of novel pumping machine feed nozzles, frame hinging base plate, discharging elbow, reducer pipe, upper cone and interface including being sequentially connected setting are sealedly connected on the lower cone outside upper cone, pressurized gas interface is welded on the discharging elbow, it is directed toward reducer pipe axially oppositely extending direction in the direction of the pressurized gas interface, it is provided with vortex air interface on the interconnecting piece of the lower cone, cavity is surrounded between the interconnecting piece and the tail portion of upper cone and has the slit air stream outlet by being formed between upper cone tail portion outer wall and lower cone inner wall.The frame hinging base plate, discharging elbow, reducer pipe and upper cone are welding or integral structure.The utility model, which can send to be isolated with high-pressure vortex wind by high voltage direct current wind, to be lubricated, and to reduce the friction between concrete material and feed nozzle inner wall, and is flowed out concrete material with cyclone mode, is reduced the occurrence probability of plugging.

Description

A kind of novel pumping machine feed nozzle

Technical field

The utility model relates to quotient's concrete pumping arrangement technical fields, more particularly to a kind of novel pumping machine feed nozzle.

Background technique

The slump of concrete mix passes through the concrete of pipeline mix not less than 10cm and with concrete pump. It is required that its good fluidity, aggregate size is generally no greater than a quarter of caliber, and need to be added prevents concrete mix from pumping The pumping admixture for isolating and blocking in pipeline, and the additive for enabling concrete batching system smoothly to pass through under pump pressure, water-reducing agent, Plasticiser, air-entrainment and thickener etc. can be employed as pumping admixture.Suitable mixing material is added, can avoid in concrete construction Mix and stir material laminated segregation, bleeding and blocking conveyance conduit.

Current feed nozzle is usually integrated single-stage/multi-stage reducing bend pipe spray head, since the viscosity of quotient's concrete itself is special Point, easily generation is sluggish during transportation, blocks the problems such as bend pipe spray head occurs.

Utility model content

Place in view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of novel pumping machine feedings Spray head solves asking for the blocking feed nozzle in the conveying of quotient's concrete using the conveying of air-flow auxiliary and air-flow bed course lubrication, separation principle Topic.

The purpose of this utility model is achieved through the following technical solutions:

A kind of novel pumping machine feed nozzle, including be sequentially connected setting frame hinging base plate, discharging elbow, reducer pipe, on Cone and interface are sealedly connected on the lower cone outside upper cone, are welded with pressurized gas interface on the discharging elbow, described Reducer pipe axially oppositely extending direction is directed toward in the direction of pressurized gas interface, and it is empty to be provided with vortex on the interconnecting piece of the lower cone Gas interface, surrounded between the interconnecting piece and the tail portion of upper cone cavity and have by upper cone tail portion outer wall and lower cone inner wall it Between the slit air stream outlet that is formed.

In order to be better achieved the utility model, the frame hinging base plate, discharging elbow, reducer pipe and upper cone be welding or Integral structure.

The utility model compared with the prior art, have the following advantages that and the utility model has the advantages that

The utility model, which can send to be isolated with high-pressure vortex wind by high voltage direct current wind, to be lubricated, and is sprayed to reduce concrete material and feeding Friction between head inner wall, and flow out concrete material with cyclone mode, reduce the occurrence probability of plugging.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is not It is limited to this.

Embodiment

As shown in Figure 1, a kind of novel pumping machine feed nozzle, frame hinging base plate 1, discharging elbow including being sequentially connected setting 2, reducer pipe 3, upper cone 4 and interface are sealedly connected on the lower cone 5 outside upper cone 4, are welded with height on the discharging elbow 2 Gas interface 6 is pressed, the axial oppositely extending direction of reducer pipe 3 is directed toward in the direction of the pressurized gas interface 6, the lower cone 5 It is provided with vortex air interface 7 on interconnecting piece, cavity 51 is surrounded between the interconnecting piece and the tail portion of upper cone 4 and has by epicone The slit air stream outlet 52 formed between 4 tail portion outer wall of body and 5 inner wall of lower cone.

In order to which the utility model is better achieved, the frame hinging base plate 1, discharging elbow 2, reducer pipe 3 and upper cone 4 are weldering It connects or integral structure.

When using utility model device, concrete material enters discharging elbow 2 along arrow A, then by high direct voltage wind by B arrow Direction accelerates to blow to reducer pipe 3, concrete material at lower cone 5 by another strand of high-pressure blast by C arrow direction through upper cone 4 and lower cone Cavity 51 between 5 becomes being vortexed wind, is blown into conveying pipeline.

Vortex wind, which is formed by, by the cavity 51 between upper cone 4 and lower cone 5 forms one layer of sky in 5 inner wall of lower cone Air film, reduces the friction of concrete material and inner wall, and flows out concrete material in rotary manner, reduces the occurrence probability of plugging.

In conclusion description through this embodiment, can make those skilled in the art's better implementation this programme.
