Description
Technical field
The present invention relates to low-temperature storage tank field, and in particular to a kind of mounting structure of low temperature horizontal tank detection means.
Background technology
Low temperature horizontal tank（There are inner bag and shell, inner bag fills medium for deep cooling medium）The structure of level gauging and temperature-detecting device is installed,
At present, the situation that level gauging and temperature-detecting device are used on individual layer storage tank is more, is generally equipped with the individual layer storage tank of deep cooling medium, just level gauging and temperature-detecting device can be inserted directly into storage tank by welding a joint in tank top；After installing, one layer of insulating foam layer of storage tank outer wall bag, whole installation process is simple, and measurement accuracy is high, will not also cause other monkey wrench when level gauging and temperature-detecting device contraction are driven when being filled with liquid after-contraction in storage tank.
But, the low temperature horizontal tank equipped with deep cooling medium, it has inner bag（Inner bag material S30408）And shell（Enclosure material can be Q345R, Q245R and S30408 etc.）, inner bag fills deep cooling medium, at the two ends of storage tank provided with two saddles, one saddle is in fixing end, another saddle is in sliding end, after storage tank inner bag is filled with deep cooling medium, because sheet material has the situation of shrinkage afterwards to the cold, therefore the inner bag in sliding end can shrink toward fixing end, shell is to be constantly in motionless state, now because level gauging and temperature-detecting device can only right angle settings, and waveguide pipe must be inserted perpendicularly into inner bag, therefore when storage tank inner bag is shrinking toward fixing end level gauging and temperature-detecting device can be driven to move together, and interlayer interior conduit right angle setting, there is no any flexible compensation, weld seam between level gauging and temperature-detecting device and shell often causes weld cracking because of shrinking, even cause inner bag joint problems of crack.Therefore, double-deck low temperature horizontal tank because the factors such as installation question never have any use experience；For common low temperature horizontal tank, the differential pressure type level gauge all used in the past, but differential pressure type level gauge sampling system is complicated, connecting line is long, and valve is more, easily block or reveal, and due to transmitter sense be differential pressure, any slight leakage will all have a strong impact on measurement, and for vacuum system, slight leakage is often difficult to be noticeable；The composition error of measurement is big, and transmitter measures the limited precision of differential pressure, along with the factor such as unstable of fluid column in sampling line causes the composition error of actual measurement larger.
The content of the invention
In order to solve the above-mentioned technical problem, the invention reside in a kind of low temperature horizontal tank is provided, to solve to easily cause the problems such as detection means is damaged because inner bag shrinks in the prior art.
For above-mentioned technical problem, the present invention proposes a kind of low temperature horizontal tank, including tank body, the tank body includes shell and loaded on the inner bag in the shell, the inner bag is connected by support with the shell, wherein, one end of the inner bag is the fixing end fixed relative to the shell, the other end is the sliding end that can be slided relative to the shell, the top of the tank body and close to the inner bag fixing end position be provided with to installation detecting device mounting seat, the inner bag opens up the first perforate close to the position of fixing end, the shell just opens up the second perforate to the position of first perforate；The mounting seat includes：Straight tube, flange and bit shift compensation structure.One end of the straight tube is fixed on first position of opening and connects the inner bag, and the other end is through the protruding shell of second perforate；Flange is fixed on one end that the straight tube stretches out the shell；Bit shift compensation structure is set in the outside of the straight tube, and one end of the bit shift compensation structure is fixedly connected with the outer wall of the shell, and the other end is fixedly connected with the flange.

Embodiment
Embodying the exemplary embodiment of feature of present invention and advantage will describe in detail in the following description.It should be understood that the present invention can have various changes in different embodiments, it is neither departed from the scope of the present invention, and explanation therein and diagram are treated as purposes of discussion in itself, and is not used to the limitation present invention.
Structure, function and the principle of the low temperature horizontal tank of the present invention are described in detail below in conjunction with a preferred embodiment.
Embodiment one
Refering to Fig. 1, the low temperature horizontal tank of the present embodiment, including tank body and mounting seat, mounting seat are used for installation detecting device 1.
It should be noted that detection means 1 can be liquid level detection device, temperature-detecting device or its detection means combined etc..
Tank body includes：Shell 2 and loaded on the inner bag 3 in shell 2, inner bag 3 is connected by support with shell 2, wherein, one end of inner bag 3 is the fixing end fixed relative to shell 2, the other end is the sliding end that can be slided relative to shell 2, mounting seat is arranged on the top of tank body and close to the position of the fixing end of inner bag 3, and inner bag 3 opens up the first perforate 31 close to the position of fixing end, and shell 2 just opens up the second perforate 21 to the position of the first perforate 31.First tapping 31 of inner bag 3 sets joint 32.
In the present embodiment, mounting seat, which should try one's best, is located on the position of inner bag 3 fixing end, and it is to after deep cooling medium is filled with inner bag 3, reduce the displacement during contraction of inner bag 3 on the position to the full extent so to install.
Mounting seat includes：Displacement collocation structure is bellows 43 in straight tube 41, flange 42 and bit shift compensation structure, the present embodiment.One end of straight tube 41 is fixed on the position of the first perforate 31 and connects inner bag 3, and straight tube 41 is fixedly connected by joint 32 with inner bag 3；The other end is through the protruding shell 2 of the second perforate 21.Flange 42 is fixed on one end that straight tube 41 stretches out shell 2.Bellows 43 is set in the outside of straight tube 41, and one end of bellows 43 is fixedly connected with the outer wall of shell 2, and the other end is fixedly connected with flange 42.
The aperture of second perforate 21 is more than the external diameter of straight tube 41 and causes there is gap between the perforate 21 of straight tube 41 and second.
In the outer wall parcel flexibly thermal insulation material of straight tube 41, the present embodiment, the flexibly thermal insulation material is aluminium-foil paper and all-glass paper.More preferably, aluminium-foil paper and all-glass paper are wrapped in the outer wall of straight tube 41, effectively reduce the leakage heat of straight tube 41.
Detection means 1 includes waveguide pipe 11.The waveguide pipe 11 of detection means 1 is stretched into inner bag 3 by the perforate of flange 42 through straight tube 41, and flange is provided with detection means 1 and is connected by the flange with the flange 42 in mounting seat.
After the inner bag of low temperature horizontal tank is filled with deep cooling medium, inner bag is gradually shunk from sliding end toward fixing end, so as to be shunk together with motion detection device, but the fixing end for being located proximate to inner bag installed due to the detection means of the present embodiment, thus shrink displacement smaller, the bellows in the mounting seat of detection means can carry out bit shift compensation to straight tube in addition, the detection means because caused by shrinking inner bag is thus effectively prevent to ftracture, and inner bag joint cracking causes inner bag to be revealed, the problems such as interlayer between inner bag and shell loses vacuum, ensure the liquid level and temperature conditions in accurate measurement tank, it ensure that the security of low temperature horizontal tank.
