Description

The defeated pressure slow-released system of mortar pipe

Technical field

The present invention relates to a kind of pipeline pressure to discharge system, more particularly to a kind of defeated pressure slow-released system of mortar pipe, belongs to Mining machinery.

Background technology

It is well known that using pipeline filling mortar during, usually can because mortar flow velocity is too fast and caused by pipeline Wear, cause mortar to leak, influence subsurface environment and safety in production；Pipe explosion accident is also occurred that during serious wear, influences to produce It is normally carried out.In order to reduce the flow velocity of mortar in pipeline, some mines are using open arrangement.Although which is convenient, Slurry local leakage, trouble point can be caused more, it is necessary to keep maintenance in open parts-layout special messenger negative value, human cost is higher.

The content of the invention

In view of the above defects of the prior art, the present invention is intended to provide one kind can reduce particle slurry flow velocity, protect Demonstrate,prove the slurry defeated pressure slow-released system of mortar pipe that continuous uniform flows in pipeline.

To achieve these goals, the present invention uses following technical scheme：It includes stretching into funnel-shaped container from top Sand-feeding tube；Container is closed structure, and there is buffer unit in the position inside the container close to upper position；The buffer unit is by extremely Few two pieces be in tilted layout formed every sieve, the adjacent incline direction every sieve is opposite；Vomit pipe with baiting valve is arranged at the bottom of container, There is the exhaust pipe with check valve at the top of container.

Respectively every the angle of inclination of sieve be 15~45 °；Injection direction is fixedly arranged above along container in the buffer unit Multiple nozzles that wall tangential direction tilts down, each nozzle are connected by flush pipe with high-pressure water pipe respectively；In the buffering dress The lower section put is fixed with other multiple nozzles that injection direction is tilted down along container inner wall tangential direction, and each nozzle leads to respectively Other flush pipe is crossed to connect with high-pressure water pipe；On the exhaust pipe of check valve front end and it is connected to and is connected in addition with high-pressure water pipe A piece flush pipe；On the vomit pipe of baiting valve front end and it is connected to the evacuated tube with exhaust-valve.

Compared with the prior art, the present invention by adopting the above-described technical solution, there is an advantage in that：

1）The pressure in sand-feeding tube is discharged using closed container, therefore can prevent mortar from outwards splashing.

2）Mortar is trickled down when on sieve, multistage every sieve buffer stop, its flow velocity and kinetic energy due to what is be in tilted layout Significantly abatement, pipeline pressure are sufficiently sustained, so as to avoid out sandpipe Fast Wearing.

3）It can not only cut down the flow velocity and kinetic energy of mortar every sieve, and mortar, release bubble therein can also be disperseed, and Can by the bubble that is mingled with the outside pressure release of check valve, purging line course of conveying, so as to ensure slurry it is continuous, uniformly, it is full Pipe conveys；Not only the vibration produced in slurry course of conveying by entrained air bubbles and the sound had been eliminated, has improved conveying stability, but also It can guarantee that slurry accurate measurement.

Brief description of the drawings

Fig. 1 is the structure diagram of the present invention.

In figure：Into sand valve 1, sand-feeding tube 2, check valve 3, exhaust pipe 4, flush pipe 5, flushing valve 6, high-pressure water pipe 7, nozzle 8, Total water valve 9, exhaust-valve 10, evacuated tube 11, vomit pipe 12, baiting valve 13, container 14, every sieve 15.

Embodiment

The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1：Closed container 14 is in funnel-shaped structure, and there is buffering in the position close to upper position inside the container Device；The buffer unit is in tilted layout by two pieces and what incline direction was opposite is formed every sieve 15, is every the angle of inclination of sieve 15 respectively 15~45 °.Have above the buffer unit from top and stretch into the sand-feeding tube 2 in container 14 and the exhaust with check valve 3 Pipe 4；There is the vomit pipe 12 with baiting valve 13 in the bottom of container 14.

In the above-mentioned technical solutions, the flow velocity and kinetic energy of mortar can not only be cut down every sieve 15, and mortar can also be discharged In bubble.

In order to avoid mortar adheres to and freezes solidly on the inner wall of container 14, injection side is fixedly arranged above in the buffer unit To the multiple nozzles 8 tilted down along 14 inner wall tangential direction of container, each nozzle 8 is connected by flush pipe 5 and high-pressure water pipe 7 respectively It is logical.Similarly, in order to avoid mortar adheres to and freezes solidly on the inner wall of container 14, injection side is fixed with below the buffer unit To the other multiple nozzles 8 tilted down along 14 inner wall tangential direction of container, each nozzle 8 passes through other flush pipe 5 respectively Connected with high-pressure water pipe 7.

In the above-mentioned technical solutions, the nozzle 8 of setting is tilted down, eddy flow can be formed along 14 inner wall tangential direction of container, Inner wall efficiency is rinsed to improve.

Similarly, in order to avoid mortar adheres to and blocks exhaust pipe 4, on the exhaust pipe 4 of 3 front end of check valve and it is connected to and height The other flush pipe 5 that pressure pipe 7 connects.

In order to avoid mortar blocks vomit pipe 12, on the vomit pipe 12 of 13 front end of baiting valve and it is connected to exhaust-valve 10 Evacuated tube 11.Having served as material container 14, to deposit material more or when blocking, and exhaust-valve 10 plus water flushing is opened, by the thing of deposition Material is discharged into sedimentation basin along evacuated tube 11（Not shown in figure）Among.

In order to easy to use, it is provided with the sand-feeding tube 2 in above-described embodiment into being mounted in sand valve 1, each flush pipe 5 Total water valve 9 is installed in flushing valve 6, high-pressure water pipe 7.
