Description

Container, molecular sieve tank and refrigerator

Technical Field

Background

Molecular sieves are increasingly widely used in daily industrial applications, and are gradually expanded into daily life applications, so that the molecular sieves have good selectivity and availability. For example, molecular sieve is applied to refrigerator, gas is introduced from the air inlet channel of refrigerator, then enters the tank body from the air inlet of molecular sieve tank, and molecular sieve material selectively adsorbs components in the gas to purify the gas with certain purity, which is beneficial to the fresh-keeping function of refrigerator.

When gas flows through the molecular sieve material, the generated reaction can cause the particles of the molecular sieve material to be loose and pulverized, sedimentation can occur in the molecular sieve tank, the compactness is affected, and the adsorption effect and the purity of produced gas are further affected. In order to maintain effective adsorption and gas purity, the molecular sieve material needs to be tightly compacted. However, since the molecular sieve needs to be tightly compacted in use, in the prior art, an elastic member such as a spring is often provided between the filter cover plate and the top cover. The spring is required to be filled into the molecular sieve filling tank under the pre-compression state, so that the risk of slipping and popping out easily occurs when a common user performs maintenance operation, and accidents or excessive exposure, splashing or scattering of the molecular sieve are caused. Under non-professional operation, the common user of spring travel and tension cannot judge the situation that the excessive filling and the insufficient filling are easy to cause, so that the molecular sieve after maintenance is invalid or insufficient in efficacy, and normal use cannot be met. Thus, the prior art has the following drawbacks:

1. can lids that use a general elastic means to provide a compression force are inconvenient to install;

2. the compaction force of the elastic material changes along with the travel, so that the compaction is possibly not real, and partial or complete failure is caused;

Detailed Description

The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown.

Example 1

The embodiment provides a container 1, in particular a molecular sieve tank 2, granular molecular sieve materials are filled in the tank, and the molecular sieve materials are tightly compacted, so that the container has an adsorption function, and can be used in a refrigerator and a filter drier.

As shown in fig. 1-4, the container 1 includes a body 10, an outer cover 20 and an attaching structure 30, wherein a molecular sieve material (not shown in the drawings) is filled in the body 10, the outer cover 20 is connected with the body 10, and an air inlet 21 is provided on the outer cover 20, in this embodiment, the air inlet 21 is processed into a pagoda head structure, and in other embodiments, the air inlet 21 can also be processed into a screw or bayonet or a quick-joint structure as shown in fig. 4 according to connection requirements, and various modes such as integral processing, split combination, welding and the like can also be adopted.

The attaching structure 30 is disposed in the container 1, and in this embodiment, the attaching structure 30 is specifically an airbag 31 made of a soft material, the airbag 31 includes an air inlet end 32, the air inlet end 32 communicates with the air inlet 21, and the state of the airbag 31 includes an initial state and a deployed state.

When the airbag 31 is in the initial state, the gas is not introduced into the gas inlet 21, the airbag 31 is in the undeployed state without air pressure support, and part of the airbag 31 can be attached to the surface of the molecular sieve material.

When the airbag 31 is in the deployment state, the air inlet 21 is filled with air, the air pressure deploys the airbag 31, and one end of the airbag 31 is pressed against the surface of the molecular sieve material along the deployment direction a, in this embodiment, the deployment direction a is a direction in which the airbag 31 is driven to approach and contact the surface of the molecular sieve material by the air pressure acting force.

In other application embodiments, a spring can be used in the molecular sieve tank 2 to realize the pressing force to the surface of the molecular sieve material, but when the body 10 and the outer cover 20 are connected, the elastic force of the spring can generate resistance, and slipping is easy to occur, so that the molecular sieve tank 2 is difficult to install; after the installation, as the gas flows through the molecular sieve material, the molecular sieve material will be settled in the container 1, and the spring with a fixed length is difficult to ensure enough pressing force in the settling process, unlike the container 1 adopting the air bag 31, when the air bag 31 is in the initial state, the air inlet 21 is not filled with the gas, the air bag 31 is not supported by air pressure and is in the undeployed state, so that when the outer cover 20 is connected with the body 10, the undeployed air bag 31 has no acting force on the outer cover 20, and no resistance is generated on the outer cover 20 when the outer cover 20 is screwed, thereby the outer cover 20 and the body 10 are easy to install. When the airbag 31 is in the unfolding state, that is, the air inlet 21 is filled with air pressure to unfold the airbag 31, so that the air pressure drives one end of the airbag 31 to be pressed against the surface of the molecular sieve material along the unfolding direction A, the molecular sieve material is tightly compacted, the internal clearance of the tightly compacted molecular sieve material is small, and the effective adsorption effect and the gas production purity can be generated. And when the pressure is released, the gas is stopped from being introduced, the molecular sieve materials are mutually recovered to a loose state, the waste discharge is convenient, and the ventilation efficiency is improved.

By adopting such an airbag 31 having a collapsible (expanded state and unexpanded initial state), the container 1 reduces the number of components, satisfies the requirement of easy installation, reduces the difficulty of controlling the filling amount of the molecular sieve, and avoids the potential safety hazard caused by slipping of the elastic member. Meanwhile, the molecular sieve material is propped against the surface of the molecular sieve material after being unfolded, and the propping force can be flexibly adjusted by adjusting the air pressure, so that the molecular sieve material is always kept in a tightly compacted state, namely the molecular sieve material is always kept with an effective adsorption effect. The airbag 31 capable of maintaining a stable pressure in this way is also called a pressure maintaining airbag. In other embodiments, according to different filling materials, the length of the airbag 31 deployed can be changed by adjusting the air pressure, so that different deployment strokes can be flexibly adjusted to adapt to different filling materials.

Wherein, when the airbag 31 is in the unfolded state, the airbag 31 is always in contact with the filled molecular sieve material, namely, the airbag 31 with proper size is selected or the height of the filling material in the body 10 is adjusted, so that the filling height does not exceed the maximum unfolding formation of the airbag 31. Therefore, the air bag 31 can always contact the surface of the molecular sieve material in the unfolding process of gradually unfolding to the maximum stroke, the necessary pressing force is maintained, and the effective adsorption effect is ensured.

Wherein, the ratio of the flow rate of the gas introduced from the gas inlet 21 to the air permeability of the air bag 31 is not less than a first coefficient, so that the air bag 31 maintains the pressing force against the molecular sieve material. In this embodiment, the first coefficient is preferably 20. By adopting the air bag 31 and the introduced gas flow rate conforming to the above proportional relationship, the sufficient pressing force on the surface of the molecular sieve material is ensured, the loosening is avoided, and the effective adsorption effect is ensured. Moreover, the relation between the compaction degree of the molecular sieve and the design flow is stable, the compaction degree is not influenced even if the molecular sieve is partially pulverized, and the purity of produced gas is more stable. In other embodiments, the first coefficient may be adjusted accordingly, depending on the material being filled or the need for compaction effects.

As shown in fig. 2, the air bag 31 specifically further includes a circumferential wall 33 and a bottom 34, where the circumferential wall 33 and the bottom 34 are connected and enclose an inner cavity 35, and the air inlet end 32 is an opening of the inner cavity 35. The annular wall 33 presents a corrugated shape, with one end at the inlet end 32 being the fixed end and the bottom 34 at the other end of the annular wall 33 being the movable end. The fixed end adopts a certain hardness and shapable material to prop up the corrugated annular wall 33 circumferentially to form a corrugated tubular structure with a certain diameter, the fixed end can be fixed in the outer cover 20 in a clamping connection mode, and when gas is introduced, the bottom 34 is driven to be unfolded by air pressure, and the multi-layer corrugated structure of the whole body of the annular wall 33 is driven to be gradually unfolded. Such a ring wall 33 is also called a stationary ring wall 33, whereas the soft bottom 34 is blown by the gas into a bulge shape.

The airbag 31 thus constructed, when the airbag 31 is in an initial state, the gas is not poured into the inner cavity 35, and the soft bottom 34 can be attached to the surface of the molecular sieve material; when the airbag 31 is in the deployed state, air is introduced into the inner chamber 35, the air pressure acts on the bottom 34 to drive the annular wall 33 to deploy along the deployment direction a, and the air pressure presses the annular wall 33 against the circumferential inner wall of the container 1 in the radial direction of the container 1, so that the force of fixing the airbag 31 on the inner wall of the container 1 is increased, and the sliding is placed. The bottom 34 presses against the surface of the molecular sieve material in the direction of deployment a.

With the above arrangement, the annular wall 33 achieves contraction and expansion in two states (initial state and expanded state); in the deployed state, the bottom 34 of the airbag 31 is forced by the gas pressure to maintain the pressure against the molecular sieve material by the bottom 34 to control the necessary deployment depth and gas volume within the container 1. The airbag 31 in this state has a fully opened opening, is easy to be inflated, and an adsorbent material or the like may be added to the bottom 34 for prefiltering moisture or a part of non-target gas.

In other embodiments, the attachment structure 30 may be other devices or products capable of achieving a telescopic state and a pressing effect, and is not limited to an airbag structure. Alternatively, the balloon may take other configurations to achieve the telescoping state and the pressing material function. For example, the air bag may take a form similar to a bicycle inner tube in which the air inlet end of the air bag is sealingly connected to the air inlet opening by a valve or other air tube, and the air bag further includes an air bag body (i.e., attachment body) having a partial region attached to the surface of the molecular sieve material as an abutment end. The air inlet end and the inner cavity of the air bag body are communicated, when air is introduced, the air enters from the air inlet end and is poured into the inner cavity of the air bag body to expand the air bag body, so that the air pressure drives the air bag body with the abutting end to abut against the surface of the molecular sieve material.

As shown in fig. 1, the body 10 includes a connecting portion 11 connected to the outer cap 20, and the container 1 further includes a sealing member 40, in this embodiment, the sealing member 40 is an O-ring, and is made of rubber. The O-shaped sleeve is sleeved on the connecting part 11 and is arranged between the body 10 and the outer cover 20, so that the sealing between the body 10 and the outer cover 20 is realized, the gas introduced into the outer cover 20 cannot leak from a gap between the body 10 and the outer cover 20, and the pressure of the air bag 31 on the molecular sieve material is ensured.

In other embodiments, other devices or products capable of achieving a seal may be used, and other materials having a sealing effect may be used for the sealing member 40. Alternatively, since the airbag 31 is soft, a part of the airbag 31 may be wrapped around the connecting portion 11, and since the airbag 31 is soft, a part of the airbag 31 attached to the connecting portion 11 is elastic, sealing between the body 10 and the outer cover 20 can be achieved, thereby ensuring the pressing force of the airbag 31 against the molecular sieve material.

Wherein the coupling portion 11 of the body 10 is an external thread, and the outer cap 20 has an internal thread on an inner surface thereof coupled with the body 10, so that the body 10 is screw-coupled with the outer cap 20.

In other embodiments, the body 10 and the outer cover 20 may be connected together by bayonet fastening or externally hung clamping. For example, as shown in fig. 3, the body 10 is provided with a plurality of protruding structures 12 along the circumferential surface of the body 10, the outer cover 20 is provided with clamping grooves along the circumferential surface of the outer cover 20 and at corresponding positions of the protruding structures 12, and the protruding structures 12 are in clamping connection with the grooves. The installation of the body 10 and the outer cover 20 can be realized by adopting threaded connection or clamping connection, and the operation is simple.

In other embodiments, the container 1 of the present embodiment may also be used in products filled with other particulate materials, and is not limited to the molecular sieve tank 2.

Example 2

The present embodiment provides a refrigerator including a molecular sieve tank 2 as in embodiment 1, a filter in the refrigerator, an air inlet 21 of the molecular sieve tank 2 communicating with an air inlet passage of the refrigerator leading to the filter, directly utilizing the pressure of air leading to the filter as a power for pressing the molecular sieve material without requiring an additional pressing structure (e.g., a spring) to generate pressing force. When the spring is used, the spring is disposed in the body 10 or the outer cover 20 of the molecular sieve tank 2, and the spring is pressed against the surface of the molecular sieve material through a cover plate, but when the body 10 and the outer cover 20 are connected, the molecular sieve tank 2 of this type is difficult to install due to easy slipping caused by the elastic force of the spring, and meanwhile, the proper structure is required to be designed to fix the spring, so that the structure is complex, while the structure is simplified by adopting the airbag 31 which can be expanded and contracted in the embodiment 1, so that the requirement of easy installation can be met, and the pressing force can be flexibly adjusted to keep the tightly compacted state on the surface of the molecular sieve material after the expansion, so that the effective adsorption effect and the gas generating purity can be generated.
