Description

A kind of coal sample bottle of variable volume

Technical field

The utility model relates to coal sample detection technique fields, in particular to a kind of coal sample bottle of variable volume.

Background technique

The full-automatic sample-preparing system of coal largely uses sample bottle realization to store obtained coal sample at present, in case Subsequent chemical examination, use of filing for reference.The coal sample bottle of existing equipment producer all has the characteristics that body is lesser, the reason is that: (1) bottle body volume It is small, sample bottle parking space is saved, and be conducive to subsequent pneumatic transfer；(2) small and exquisite bottle body advantageously reduces sample bottle conveying, envelope Link volume is filled, and then reduces production cost；(3) small and exquisite bottle body makes air content in bottle few, and coal varitation is small.

However coal sample bottle body is smaller that there are a very big drawbacks --- there are the risks of larger coal qualities test error.Reason Be: coal is a kind of mixture that structure is complicated, composition is inhomogenous, therefore before coal qualities test, need to be sufficiently mixed coal sample, such as The coal sample in sealing container " before weighing coal sample, should be sufficiently mixed by regulation in total moisture determination method in GB/T 211-2007 coal At least 1min ".Lesser spatial volume is unfavorable for coal sample in bottle and is sufficiently mixed, and it is big in turn result in coal qualities test resultant error.Together When to guarantee testing result accuracy and sample to be avoided to pollute, coal sample cannot be transferred in other mixing arrangements or using stirring Stick mixing, and be mixed edge using stirring rod and mix uneven phenomenon.

Utility model content

The purpose of this utility model is to provide a kind of coal sample bottles of variable volume.

In order to achieve the above object, the utility model proposes an a kind of coal sample bottles for variable volume, which is characterized in that including bottle Lid, limitation ring, coal sample bottle top half, coal sample bottle lower half portion and liner；Wherein:

Coal sample bottle top half is cylindrical shape, and the inner wall in the lower part of cylinder is equipped with internal screw thread, coal sample bottle lower half portion It is opening up barrel shape, the outer wall on the top of drum is equipped with external screw thread, coal sample bottle top half and coal sample bottle lower half Part is connected through a screw thread；

The apical lateral of the limitation ring side is equipped with downward opening groove；On axial cross section, the shape of groove is Downward opening " C " font；

Liner is barrel shape, and liner at the bottom is fixed on the bottom surface with coal sample bottle lower half portion；The top of liner open end It is fixed on the inner side wall of groove, and the top of coal sample bottle top half is in groove, and is located at the top of liner open end It is leaned between nonlocal side wall with groove；The side wall of liner is telescopic；

The top outer wall of the stop collar side is equipped with external screw thread, and the inner wall of bottle cap open end is equipped with internal screw thread, bottle cap with Limitation ring outer wall is connected through a screw thread.

Further, wherein the liner is high elastic rubber liner.

In conclusion the existing small coal sample bottle conveying of the coal sample bottle of the utility model, storage advantage, also can effectively reduce coal quality Result of laboratory test error.

It should be appreciated that as long as aforementioned concepts and all combinations additionally conceived described in greater detail below are at this It can be viewed as a part of the utility model theme of the disclosure in the case that the design of sample is not conflicting.In addition, being wanted All combinations of the theme of protection are asked to be considered as a part of the utility model theme of the disclosure.

The foregoing and other side of the utility model introduction can be more fully appreciated from the following description in conjunction with attached drawing Face, embodiment and feature.The features and/or benefits of other additional aspects such as illustrative embodiments of the utility model To be obvious in the following description, or will be learnt in the practice by the specific embodiment instructed according to the utility model.

Detailed description of the invention

Attached drawing is not intended to drawn to scale.In the accompanying drawings, identical or nearly identical group each of is shown in each figure It can be indicated by the same numeral at part.For clarity, in each figure, not each component part is labeled. Now, by by example and be described in reference to the drawings the utility model various aspects embodiment, in which:

Fig. 1 is the structural schematic diagram of the coal sample bottle of the variable volume of the utility model.

Specific embodiment

In order to know more about the technology contents of the utility model, spy lifts specific embodiment and institute's accompanying drawings is cooperated to be described as follows.

It is described with reference to the various aspects of the utility model in the disclosure, shown in the drawings of the implementation of many explanations Example.It is not intended to cover all aspects of the utility model for embodiment of the disclosure.It should be appreciated that a variety of structures presented hereinbefore Think and embodiment, and those of describe in more detail below design and embodiment can in many ways in any one Implement, this is because conception and embodiment disclosed in the utility model are not limited to any embodiment.In addition, this is practical Novel disclosed some aspects can be used alone, or with it is disclosed by the utility model it is otherwise it is any it is appropriately combined come It uses.

As shown in Figure 1, a kind of coal sample bottle of variable volume provided by the utility model, including coal sample bottle cap 1, coal sample bottle Top half 2, high elastic rubber liner 4, is threadedly coupled area 5 and limitation ring 6 at coal sample bottle lower half portion 3.In diagram, label 10 Indicate coal sample.

Coal sample bottle top half 2 is connected through a screw thread area 5 with coal sample bottle lower half portion 3 and connect；Under high elastic rubber liner 4 Portion is fixed with 3 adhesion of coal sample bottle lower half portion；4 top of high elastic rubber liner is fixed with 6 adhesion of limitation ring；The coal sample bottle upper half 2 are divided to be embedded in limitation ring 6, and coal sample bottle top half 2 can be freely rotated in limitation ring 6；Coal sample bottle cap 1 and limitation 6 outer wall of ring is connected through a screw thread.

When prepared by coal sample, the width in connection screw thread area 5 is most narrow, and high elastic rubber liner 4 is in nature relaxed state at this time, Coal sample bottle height degree is minimum, and volume is minimum.After the completion of coal sample preparation, coal sample bottle is sealed using coal sample bottle cap 1, passes through sample Sample bottle is transmitted to laboratory and storage sample cabinet by the pneumatic movement system of product bottle.

When coal qualities test, the rotation opposite with coal sample bottle lower half portion 3 of coal sample bottle top half 2, coal sample bottle top half 2 exists Rotation in limitation ring 6 is threadedly coupled area 5 and constantly widens, until maximum width, high elastic rubber liner 4 is in tension-like at this time State, coal sample bottle height degree reach highest, and volume reaches maximum.Coal sample in sealing container is mixed thoroughly for a minimum 1min, then into Row chemical examination.

After the completion of chemical examination, coal sample bottle top half 2 and 3 opposite direction rotating of coal sample bottle lower half portion, until being threadedly coupled area 5 Width reaches most narrow, and high elastic rubber liner 4 replys relaxation, covers coal sample bottle cap 1, coal bottle is replaced.

Although the utility model has been disclosed with preferred embodiment as above, so it is not intended to limit the utility model.This reality It is without departing from the spirit and scope of the utility model, each when that can make with novel those of ordinary skill in the art Kind changes and retouches.Therefore, the protection scope of the utility model is subject to view those as defined in claim.
