Enter in the sampler before silo at powders such as a kind of cement of the present utility model, breeze and flyash, described reduction valve and controlled valve are integral type structure.
Enter in the sampler before silo at powders such as a kind of cement of the present utility model, breeze and flyash, the length of described sampling pipe is less than the length that samples flexible pipe, and the connector vertical welding of sampling pipe is on discharging steel pipe, and the main body pipeline fixing with described connector is parallel with described discharging steel pipe.
Enter in the sampler before silo at powders such as a kind of cement of the present utility model, breeze and flyash, described sampling flexible pipe is fixed on described discharging steel pipe by many solid pipe racks bindings.
Enter in the sampler before silo at powders such as a kind of cement of the present utility model, breeze and flyash, between described sampling pipe and sampling flexible pipe, be provided with the pipe clamp of fixing use.
Based on above-mentioned technology contents, there is following technological merit compared with the joint form of rapid-acting coupling of the present utility model and prior art:
1. the sampling method that the powder such as a kind of cement of the present utility model, breeze and flyash enters in the sampler before silo has replaced original sampling method, sampler of the present utility model is arranged on discharging steel pipe, by selecting the sampling flexible pipe of appropriate length to make to sample the mouth of pipe height of flexible pipe suitable, facilitate staff's sampling on the ground of standing.Reduce staff's labor force and work difficulty, saved the step that staff climbs gas and unloads powder tank car, improved the security of work.
2. the installation that the powder such as a kind of cement of the present utility model, breeze and flyash enters reduction valve in the sampler before silo and controlled valve not only can regulate and control the speed that powder flows out, the generation that reduces dust, can also rise and reduce tank body internal pressure, in the time that the pressure in tank body is excessive, can emit portion gas, the pressure suitably reducing in tank body prevents wharf explosion.
Accompanying drawing explanation
Fig. 1 is that the sampler that the powders such as a kind of cement of the utility model, breeze and flyash enter before silo unloads the scheme of installation on powder tank car at gas.
Fig. 2 is that the powders such as a kind of cement of the utility model, breeze and flyash enter the sampler structural representation before silo.
Embodiment
We do further and elaborate rapid sampling attachment of the present utility model with specific embodiment by reference to the accompanying drawings below; in the hope of clearer understanding structure composition of the present utility model and principle of work, but can not limit protection domain of the present utility model with this.
Please see Figure 1, Fig. 1 is that the sampler that the powders such as a kind of cement of the utility model, breeze and flyash enter before silo unloads the scheme of installation on powder tank car at gas.As seen from the figure, the installation of the utility model sampler is the one innovation improvement of gas in prior art being unloaded to powder tank car 1.
Gas unloads on powder tank car 1 and is loaded with a tank body 2, and tank body 2 is used for loading the powders such as cement, breeze and flyash.Tank body 2 is welded with discharging steel pipe 3 and strengthens version with adaptive camber fixing near the position of side bottom, discharging steel pipe 3 is connected with the inside of tank body 2.The other end of discharging steel pipe 3 connects one section of unloading rubber tube 4, and the other end of unloading rubber tube 4 is free ends, and it can be connected and transmit powder with storehouse cylinder on ground.Discharging steel pipe 3 is provided with switch valve 5, and the tank body 2 that gas unloads powder tank car 1 is filled with to be opened switch valve 5 after gas and the powders such as cement, breeze and flyash can be delivered in the cylinder of storehouse.
Before being delivered into silo, the powders such as cement, breeze and flyash need to detect constituent, grain size, the dry quality problems such as degree that wet of powder, as a new breakthrough design, our feeding detects in silo before changing mode, changes at gas and unloads and on powder tank car 1, establish a sampler.
Please see Figure 2, Fig. 2 is that the powders such as a kind of cement of the utility model, breeze and flyash enter the sampler structural representation before silo.On discharging steel pipe 3, be welded with sampling pipe 6 as can be seen from Figure.The residing position of discharging steel pipe 3 of unloading powder tank car 1 due to gas is lower, and staff is easily welded on sampling pipe 6 on discharging steel pipe 3, and facilitates staff to control reduction valve and the controlled valve 7 on sampling pipe 6.Sampling pipe 6 is welded on and on discharging steel pipe 3, neither destroys tank body 2 handled easily again.
The other end of sampling pipe 6 is connected with a sampling flexible pipe 8, can get the sampling flexible pipe 8 of suitable length according to the nozzle position height of sampling flexible pipe 8.Staff can hold sampling flexible pipe 8 and be adjusted to suitable position and sample.
Sampling flexible pipe 8 is provided with reduction valve 7, wharf explosion accident easily occurs in the time that the pressure in tank body 2 is excessive and need to implement decompression.Open reduction valve 7 portion gas in tank body 2 is emitted, close reduction valve 7 after making gaseous tension in tank body 2 reach within safety coefficient.
The connector of sampling pipe 6 is welded on discharging steel pipe 3, and the sampling pipe 6 being welded to connect is connected with discharging steel pipe 3 more firmly closely.The fixing main body pipeline of sampling pipe 6 connectors is parallel with discharging steel pipe 3.Because the main body pipeline gas of sampler unloads the salient position of powder tank car, the main body pipeline of sampler is parallel with discharging steel pipe 3, makes main pipeline be close to discharging steel pipe 3 and distributes, and can reduce and too protrude the collision causing with other things because of sampler.
As seen from Figure 2, there are many solid pipe racks 9 that 8 bindings of sampling flexible pipe are fixed on discharging flexible pipe 4.Make to sample flexible pipe 8 and distribute along discharging steel pipe 3, sampling flexible pipe 8 fixing can be avoided gas to unload and when powder tank car 1 is walked, sample rocking of flexible pipe 8, and then reduces because rocking the destruction that causes sampling flexible pipe 8.Between sampling flexible pipe 8 and sampling pipe 6, be provided with pipe clamp 10, pipe clamp 10 plays the effect of fixing sampling flexible pipe 8, makes to sample flexible pipe 8 and is connected tightr with sampling pipe 6.Pipe clamp can replace with the wire rope of sampling pipe 6 junctions with being tightened on sampling flexible pipe 8.
By said structure form and principle of work can find out a kind of gas unload powder on powder tank car 1 enter sampler sampling device cost before silo low, sample efficient and convenient, produce dust few, reduce working strength, sampler can also play the effect of decompression.
