Sandblasting cleaning device inside a kind of pipeline
The pipe installation technology such as thermoelectricity, nuclear power, water power, industry field is the utility model is related to, particularly in conventional pipelines
Portion's sandblasting cleaning device.
At present, with the stabilization of China's electric power, fast development, cleaning inside degree during pipe laying system is to whole pipeline
System or even a whole set of unit normal operation play decisive role.In Pipe installing, domestic application is more generally using a large amount of
Manually plus simple abrasive blast equipment operation carry out inner-walls of duct cleaning.And conventional pipelines clean during need by
Pipeline prestores to specified sandblasting place, needs lifting appliance to coordinate in operation process.
, problems be present in above-mentioned conventional pipeline cleaning inside scheme：
1st, cargo handling operation is more builds a larger assignment place, it is necessary to face before pipeline sandblasting operation, pipeline spray
In sand operation process, 2 personnel are at least needed to carry out the operation at scene, the bad crane gear cooperation that also to borrow in position is changed
Position, the place of occupancy is larger, faces and builds up that this is higher.Therefore economy is not strong, and sandblasting is inefficient, and advantage is failed to understand in terms of progress
It is aobvious.
2nd, because the profile of nozzle can not when traditional pipeline abrasive blast equipment is directed to the line treatment less than below DN80
In deep pipe, it is substantially and takes nozzle simple to operate, the ability for dispelling dirt has against inner-walls of duct direct injection cleaning mode
Limit, and operate cumbersome.
To sum up, the place of traditional sandblast technology shortcoming.Because the equipment purchased is more cheap, overall cost is not high, causes each
Individual electric construction unit is all still carrying out the cleaning operation of inner-walls of duct with this scheme now.In the premise that current safety is weightier than Mount Tai
Under, traditional pipeline abrasive blast equipment is also gradually impracticable.
How a kind of device is designed, and the structure of itself is simple, and cost is low, easy to operate, and it can be before safety be ensured
Put, but it is also advantageous in terms of economic and installation progress, it is the technical problem for being badly in need of solving.
Utility model content
Technical problem to be solved in the utility model is, for problem present in existing sand blasting unit, there is provided a kind of
Sandblasting cleaning device inside pipeline, it can guarantee that pipeline cleaning inside reaches code requirement, and the structure of its own is simple, cost
It is low, operation is efficient, easy to operate and safety economy, be highly suitable for the live sandblasting operation of the middle-size and small-size pipeline in scene.
Sandblasting cleaning device inside a kind of pipeline, including nozzle fixing device, bearing assembly, nozzle, rubber fittings, institute
It is in seven fonts to state nozzle fixing device, and one end is bolted on pipeline outer wall, and the other end is provided with bearing assembly, and and rubber
Rubber hose coupling welds, and the nozzle is weldingly fixed on the interior steel ring of bearing assembly and stretched into inside pipeline, the nozzle and pipe
Road inwall horizontal sextant angle is 20 ° -50 °, and rubber fittings connection rubber tube provides compressed air.
Further, nozzle is provided with 2-4, and uniform welding is in the bearing assembly of bearing assembly on steel ring, the bearing
Stationary barrier is provided with component on steel ring, the perforate of corresponding nozzle quantity is provided with the stationary barrier.
Further, pipeline cleaning inside device nozzle fixing device is adjusted according to various pipeline models and fixed.
Further, nozzle and rubber fittings are alloy wear-resisting material, and rubber tube is wear-resisting pressure leather hose.
Further, cleaning device nozzle changes swivel nozzle according to the size of caliber.
Further, cleaning device nozzle can be rotated freely by the recoil strength of compressed air and fine sand, can be in pipeline
Form spiral air-flow.
The utility model is simple in construction, easy installation, maintenance is simple, cost is cheap, is effectively carried using and can easy to operate
High operating efficiency, the labor intensity of operating personnel is reduced, in power station erecting bed strong adaptability, dirty effect of dispelling is good, particularly suitable
In the cleaning inside of small-sized caliber pipe, can at utmost improve the problem of pipeline cleaning inside is spent, and be inherently eliminated because
Caused by rust inside pipeline the problems such as line clogging, the risk of the safety and economic operation of unit is reduced.
Brief description of the drawings
Fig. 1 is the structural representation of sandblasting cleaning device inside the utility model pipeline.

Wall, the other end is provided with bearing assembly 3, and is fixedly connected with rubber fittings 4, and the nozzle 1 is weldingly fixed on bearing assembly 3
Interior steel ring on and stretch into inside pipeline 6, the nozzle 1 and the inwall horizontal sextant angle of pipeline 6 are 20 ° -50 °, and the rubber tube connects
First 4 connection rubber tube provides compressed air.Institute's nozzle 1 and rubber fittings are alloy wear-resisting material, and rubber tube is wear-resisting pressure
Specific embodiment 2
It is with the difference of specific embodiment 1：Nozzle 1 is provided with 2, bearing assembly of the uniform welding in bearing assembly
In 3 on steel ring, stationary barrier is provided with steel ring in the bearing assembly 3,2 perforates, perforate and spray are provided with stationary barrier
Mouth is corresponding.
In use, the utility model pipeline cleaning inside device nozzle fixing device 2 and bearing assembly 3 are first passed through into bearing
Component tabletting 5 is assembled, and rubber fittings 4 and nozzle 1 are tightly connected, and after assembling, is debugged inside the utility model pipeline
Whether cleaning device can normal work.The utility model pipeline cleaning inside device is adjusted according to the size of pipeline when starting operation
