Abstract

The utility model discloses an energy-saving type freezing pipe used for underwater congelation and belongs to the technical filed of underwater vertical congelation equipment. The energy-saving type freezing pipe comprises a freezing pipe, a liquid supply pipe and a liquid return pipe, wherein a sealing cover plate is fixed to the top end of the freezing pipe; a clapboard is arranged at the local freezing elevation of the freezing pipe; a thermal insulation material fills a gap between the sealing cover plate and the clapboard; the liquid supply pipe penetrates through the sealing cover pipe and the clapboard to stretch to the bottom of the freezing pipe; the liquid return pipe penetrates through the sealing cover plate and the clapboard and forms an in-pipe loop with the liquid supply pipe; an outer sleeve is arranged outside the freezing pipe; the upper end of the outer sleeve is higher than a water surface; the lower end of the outer sleeve is pressed into river bottom boil; a thermal insulation plate is arranged between the outer sleeve and the freezing pipe. During construction, the outer sleeve is striken into an about 1-meter position under the river bottom, drilling construction is carried out under the guide effect of the outer sleeve, the energy-saving type freezing pipe which is processed and completed is placed in a drill hole after the drill hole is completed, a freezing structure can be connected, and congelation starts. The energy-saving type freezing pipe for underwater congelation has the beneficial effects that the manufacturing and processing are simple and convenient, the cost is low, the use is convenient, and the loss of a cooling capacity in a non-frozen region is prevented.

Description

A kind of energy-saving freezing pipe for freezing under water

Technical field

The utility model relates to one vertical frozen equipment under water, specifically a kind of energy-saving freezing pipe for freezing under water.

Background technology

Under water when frozen construction, Wei Dong district is due in water, while freezing, mobilely take away a large amount of colds due to what cold caused the turbulent flow of water and river, river, make to freeze the loss in a large number in vain of institute's chilling requirement, waste obviously, the calculating of freezing chilling requirement is caused to interference simultaneously, make calculating and actual deviation larger, when serious, can cause the failure of consolidation by freezing construction due to the uncertainty of freeze design.

Utility model content

In order to address the above problem, the utility model provides a kind of energy-saving freezing pipe for freezing under water, utilizes this device can stop the loss of Wei Dong district cold, in saving cold, guarantees freezing efficiency.

The utility model is realized with following technical scheme: a kind of energy-saving freezing pipe for freezing under water, comprises freezing pipe, feed pipe and liquid back pipe; Described freezing pipe top is fixed with closed cover, and absolute altitude place of freezing pipe partial freezing establishes dividing plate; Between described closed cover and dividing plate, be filled with heat insulating material; Described feed pipe extends freezing pipe bottom through closed cover and dividing plate; Described liquid back pipe is through closed cover and dividing plate and form pipe inner looping with feed pipe; Described freezing pipe is provided with outer tube outward; Described outer sleeve upper is higher than the water surface, and lower end is pressed in the soil of river bed; Between described outer tube and freezing pipe, be provided with warming plate.

It is further: described heat insulating material is the granular heat insulating material of perlite.

Described warming plate is PFF warming plate.

Good effect of the present utility model is:

1, the application of outer tube, for drilling construction provides guide effect, makes borehole accuracy higher;

2, in freezing pipe, completely fill out the granular heat insulating material of perlite, the outer closely wrapping of pipe PEF warming plate, simple and convenient in operation, take full advantage of the performance of different materials;

3, the application of the granular heat insulating material of perlite and PEF warming plate can stop the not loss of freezing zone cold in freezing process, avoids waste and has guaranteed freezing efficiency;

4, compact conformation, processing and fabricating is convenient, with low cost, is extremely easy to promote the use of.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

In figure: 1, feed pipe; 2, liquid back pipe; 3, closed cover; 4, freezing pipe; 5, heat insulating material; 6, outer tube; 7, warming plate; 8, dividing plate.

Detailed description of the invention

Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.

As shown in Figure 1, a kind of energy-saving freezing pipe for freezing under water, comprises freezing pipe 4, feed pipe 1 and liquid back pipe 2; Freezing pipe 4 tops are fixed with closed cover 3, and freezing pipe 4 absolute altitude places of partial freezing establish dividing plate 8; Between freezing pipe 4 inner sealing cover plates 3 and dividing plate 8, be filled with the granular heat insulating material 5 of perlite; Feed pipe 1 extends freezing pipe 4 bottoms through closed cover 3 and dividing plate 8; Liquid back pipe 2 is through closed cover 3 and dividing plate 8 and form pipe inner looping with feed pipe 1; The outer outer tube 6 that is provided with of freezing pipe 4; The size of the size of outer tube 6 freezing pipe 4 when freezing under water determines, outer tube 6 upper ends are higher than the water surface, and lower end is pressed in the soil of river bed approximately 1 meter; By the void size between freezing pipe 4 and outer tube 6, freezing pipe 4 Wei Dong districts are closely wrapped up with PFF warming plate 7.

After machining, outer tube 6 is pressed in the soil of river bed by design position, hole with pile compacting equipment, utilizes outer tube 6 to do guide effect, in overcoat 6, complete drilling construction, the energy-saving freezing pipe of machine-shaping is lowered to and in boring, can connects freezing system start and freezed.
