Background

The low-temperature storage tank comprises an outer tank, an inner tank and a heat insulation layer, wherein an interlayer space is formed between the inner tank and the outer tank at intervals, and the heat insulation layer is positioned in the interlayer space. The heat insulating layer is made of pearlite sand (also called as expanded perlite), the pearlite sand is filled into the interlayer space, the low heat conducting performance of the pearlite sand is utilized to play a role in heat insulation of the interlayer space, and the storage tank is maintained to have a low evaporation rate.

The pearlite sand is a white granular loose material with porous structure made up by using acidic volcano vitreous lava through the processes of breaking, preheating, roasting and expansion, and has the characteristics of small capacity, low heat conductivity, good chemical stability, non-combustion, non-toxic, tasteless and sound-absorbing. When the pearlife is filled, the pearlife is firstly baked and expanded by on-site foaming equipment to form a fine particle state, and then is blown to the interlayer space by an air supply device, and the whole pearlife is in a loose state after entering the interlayer space. Because the granularity is different in size, the quality is smaller, and the particles have a rest angle, the particles can not be compacted by the self weight in a short time, so that gaps exist among the pearlife particles, and the heat insulation performance of the low-temperature storage tank is influenced. Therefore, the vibrating hammer drives the pearlife to shake in the filling process of the pearlife, so that the repose angle of the pearlife is stabilized, pearlife particles are in close contact, gaps among the particles are reduced or completely avoided, and the heat insulation performance of the low-temperature storage tank is improved.

When the preset height is 2m, namely when the height of the pearl sand filling is 2m, the lifting mechanism is controlled to ascend.

The control of the lifting mechanism is controlled by the control mechanism positioned in the outer tank, so that the situation that an operator is in a pearlized sand powder environment is effectively avoided.

And S5, continuously filling the pearlife, controlling the ring moving mechanism to move to drive the vibration hammer 25 to move, and driving the pearlife to shake through the vibration of the vibration hammer 25.

The step is the same as S3, and is not repeated herein.

And S6, continuing to control the lifting mechanism to ascend.

The step is the same as S4, and is not repeated herein.

S7, and S3 and S4 are repeated until the height of the pearl sand filling is consistent with that of the inner tank 12.

S8, after filling the pearlite, the nut between the two mounting plates 232 is unscrewed, the bolt is removed, the connection between the two pulleys 231 and the suspension member 22 is released, and the loop moving mechanism, the lifting mechanism, and the hammer 25 are removed.

That is, the ring moving mechanism, the lifting mechanism and the vibration hammer 25 of the auxiliary device 2 for filling pearlife are not in the outer tank 11 after the filling of pearlife is completed, and the normal use of the low-temperature storage tank 1 is not affected.

According to the pearly-lustre filling method, the height of the vibration hammer 25 in the interlayer space is controlled by controlling the lifting of the lifting mechanism, so that the operation of moving the vibration hammer 25 at high altitude is avoided, the safety of operators is ensured, and the operation safety is improved. The vibration hammer 25 moves by controlling the ring moving mechanism to move around the whole circle of the periphery of the inner tank 12, so that the operation without dead angles is realized, and the vibration effect is ensured.

According to the technical scheme, the invention has the advantages and positive effects that:

the auxiliary device for filling the pearlife comprises a suspension piece, a ring moving mechanism, a lifting mechanism and a vibration hammer. Through the flying piece, ring moves mechanism and elevating system and hangs the plummet in the intermediate layer space, realize the vibration effect, the low temperature storage tank for the outer jar of non-magnetism nature provides the pearlite sand filling scheme, vibration drive pearlite sand shake through the plummet, thereby the angle of repose pearlite sand's repose, make pearlite sand granule in close contact with, reduce or avoid forming the clearance between the granule completely, guarantee the closely knit packing of pearlite sand between outer jar and inner tank, improve low temperature storage tank's thermal insulation performance. And the suspension part is suspended in the outer tank and suspended at the top of the outer tank, the ring moving mechanism is in sliding connection with the suspension part, the lifting mechanism is connected with the ring moving mechanism, and the vibration hammer is connected with the lifting mechanism, so that the vibration hammer moves along with the lifting of the lifting mechanism and the ring movement of the ring moving mechanism, the operation of moving the vibration hammer at high altitude is avoided, the safety of operators is ensured, the operation safety is improved, the dead-angle-free operation is realized, and the vibration effect is ensured.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, as follows: it is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of the claims and equivalents thereof.
