Abstract
The invention belongs to filling technique fields, more particularly to a kind of antifreeze filling pipeline, including pipeline body, a nozzle directed downwardly is provided in the low spot of pipeline body, vertical liquid discharging tube is welded on nozzle, the lower end surface of liquid discharging tube is welded with ring flange, and companion flange disk setting one, which blocks, uses blind plate, and ring flange and blind plate are fixed by fastening bolt.The present invention traditional filling pipeline low spot open pipe mouth and weld liquid discharging tube, the liquid that low spot stockpiles in this way can flow into liquid discharging tube, will not there be liquid inside pipeline body, therefore it will not freeze or block pipeline, so as to ensure being normally carried out for filling operation in cold weather conditions.In actual application, it needs periodically to remove blind plate when not carrying out goaf filling, the liquid storage in the liquid discharging tube of pipeline body low spot is thoroughly released, freezed in winter is avoided to block filling pipeline.
Description
Technical field
The present invention relates to a kind of antifreeze filling pipelines, belong to filling technique field.
Background technique
After mining, the fillers such as sand, stone and water are generally mixed into mortar using hydraulic pressure, and pass through filling pipeline
Mortar is transported to goaf, goaf is filled, obturation roof supporting, country rock is formed, prevents and reduce top plate and collapse
It falls and deforms, mitigate the pressure of working face.
The winter in the north is relatively cold, and low temperature is up to subzero ten several years, in winter, filling pipeline is antifreeze be one very
Important work, but be not easy to be discharged since filling pipeline low spot is easy liquid storage and liquid, it is easy to appear filling pipeline knots
The case where ice, will cause filling pipeline blocking, influence normally to fill when serious.
Currently, there are no good modes to solve the problems, such as this.
Summary of the invention
The technical problem to be solved by the present invention is overcoming deficiency in the prior art, one kind is provided in cold weather conditions
It can guarantee that water does not freeze, ensures the antifreeze filling pipeline that filling operation is normally carried out filling pipeline down.
Antifreeze filling pipeline of the present invention, including pipeline body are provided with a pipe directed downwardly in the low spot of pipeline body
Mouthful, vertical liquid discharging tube is welded on nozzle, the lower end surface of liquid discharging tube is welded with ring flange, and companion flange disk setting one blocks
With blind plate, ring flange and blind plate are fixed by fastening bolt.
The present invention traditional filling pipeline low spot open pipe mouth and weld liquid discharging tube, the liquid that such low spot stockpiles can flow into
In liquid discharging tube, will not have liquid inside pipeline body, therefore will not freeze or block pipeline, so as to
Ensure being normally carried out for filling operation under cold weather conditions.
In actual application, it needs periodically to remove blind plate when not carrying out goaf filling, by pipeline body low spot
Liquid discharging tube in liquid storage thoroughly release, avoid freezed in winter block filling pipeline.
Preferably, the periphery of the pipeline body is coated with insulating layer, and insulating layer is coated with erosion resistant coating, passes through heat preservation
Layer can be improved the antifreezing effect of pipeline body, while carry out effective protection to insulating layer by erosion resistant coating.Similarly, in liquid discharging tube
Periphery be also coated with insulating layer, insulating layer is coated with erosion resistant coating.
Preferably, the nozzle diameter is 100mm.
Preferably, the length of the liquid discharging tube is 50mm.
Compared with the prior art, the invention has the beneficial effects that:
The present invention traditional filling pipeline low spot open pipe mouth and weld liquid discharging tube, the liquid that such low spot stockpiles can flow into
In liquid discharging tube, will not have liquid inside pipeline body, therefore will not freeze or block pipeline, so as to
Ensure being normally carried out for filling operation under cold weather conditions.In actual application, it needs do not carrying out goaf filling
When, blind plate is periodically removed, the liquid storage in the liquid discharging tube of pipeline body low spot is thoroughly released, freezed in winter is avoided to block filling pipe
Road.

Specific embodiment
The embodiment of the present invention is described further with reference to the accompanying drawing:
As shown in Figure 1, antifreeze filling pipeline of the present invention includes pipeline body 3, it is provided in the low spot of pipeline body 3
One nozzle directed downwardly, nozzle diameter 100mm are welded with vertical liquid discharging tube 4 on nozzle, and the length of liquid discharging tube 4 is 50mm,
And it is welded with ring flange 6 in the lower end surface of liquid discharging tube 4, the setting of companion flange disk 6 one, which blocks, uses blind plate 7, ring flange 6 and blind plate 7
It is fixed by fastening bolt 5.
In the present embodiment:
The periphery of pipeline body 3 is coated with insulating layer 2, and insulating layer 2 is coated with erosion resistant coating 1, can be mentioned by insulating layer 2
The antifreezing effect of high pipeline body 3, while effective protection is carried out to insulating layer 2 by erosion resistant coating 1.Similarly, in the outer of liquid discharging tube 4
Week is also coated with insulating layer 2, and insulating layer 2 is coated with erosion resistant coating 1.Wherein, polyurethane foam material can be directly used in insulating layer 2
Material.
The present invention traditional filling pipeline low spot open pipe mouth and weld liquid discharging tube 4, the liquid that such low spot stockpiles can flow
Enter in liquid discharging tube 4, will not have liquid inside pipeline body 3, therefore will not freeze or block pipeline, so as to
It is enough to ensure being normally carried out for filling operation in cold weather conditions.
In actual application, it needs when not carrying out goaf filling, periodically removes blind plate 7, pipeline body 3 is low
Liquid storage in the liquid discharging tube 4 of point is thoroughly released, and freezed in winter is avoided to block filling pipeline.
