[0003] In the transportation of chemical materials via tank trucks and storage tanks, it is generally necessary to sample and test the materials in the tanks. The existing sampling method involves operators manually filling 20L buckets with the material, removing them for testing, and then pouring the material back into the tank through a manhole on the top. However, this method carries risks of VOC emissions when the manhole is open, potentially polluting the environment. Furthermore, the pouring process may generate static electricity, which could cause a fire, posing safety concerns. Additionally, there is a risk of the buckets being accidentally dropped during the operation, leading to significant losses.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

[0005] The purpose of this invention is to provide a sealed sampling container that can prevent material leakage through the combination of a sealed container body and a lid, while achieving safe and rapid material recovery through the combination of a drain valve and an exhaust valve.

[0006] To achieve the above objectives, this utility model discloses a sealed sampling container, which includes:

[0007] A barrel body having an opening, the opening forming a cavity for holding material;

[0008] A lid, the size of which matches the opening of the barrel, is used to cover the opening of the barrel so as to seal the cavity;

[0009] An exhaust valve is disposed on the cover body. The exhaust valve has a first end and a second end disposed opposite to each other.

The first end of the drain valve is connected to the cavity, and the second end of the drain valve is connected to the pump body. The pump body is connected to the storage tank. The drain valve is used to recover the material in the cavity into the storage tank under the drive of the pump body.

[0011] As a further description of the above technical solution, the sealed sampling bucket also includes a locking cap buckle, which includes a locking cap and a locking buckle. The locking cap is located on the edge of the cover body, and the locking buckle is located on the edge of the opening of the bucket body. The positions of the locking cap and the locking buckle are matched. The locking buckle is rotatable and hooked on the locking cap. The locking cap buckle is used to press the cover body tightly and fix it on the bucket body.

[0012] As a further description of the above technical solution, the number of the locking buckles is four, and the four locking buckles are spaced apart at the quadrant points of the barrel body and the lid body.

[0013] As a further description of the above technical solution, the exhaust valve is disposed on the top surface of the cover, and the exhaust valve is disposed near the edge of the cover, and the exhaust valve is configured as a U-shaped bend with the second end bent downward.

[0032] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0033] Please see Figure 1 This embodiment provides a sealed sampling container, which includes:

[0034] The barrel 1 has an opening, and a cavity is formed inside the opening for holding the material.

[0035] The lid 2 is sized to match the opening of the barrel 1. The lid 2 is used to cover the opening of the barrel 1 so that the cavity is sealed.

[0036] The exhaust valve 3 is disposed on the cover 2. The exhaust valve 3 has a first end and a second end that are arranged opposite to each other. The first end of the exhaust valve 3 is connected to the cavity, and the second end of the exhaust valve 3 leads to the outside. The exhaust valve 3 is used to exhaust or allow air to enter the cavity.

[0037] The drain valve 4 is installed on the barrel 1. The drain valve 4 has a first end and a second end that are arranged opposite to each other. The first end of the drain valve 4 is connected to the cavity, and the second end of the drain valve 4 is connected to the pump body. The pump body is connected to the storage tank. The drain valve 4 is used to recover the material in the cavity to the storage tank under the drive of the pump body.

[0038] For the above structure, during installation, the exhaust valve 3 is placed at the top of the cover 2, the drain valve 4 is oriented towards the pump body, and the second end of the drain valve 4 is detachably connected to the inlet of the pump body.

[0039] In practical use, the operator separates the barrel 1 from the cover 2 and fills the cavity of the barrel 1 with the material to be tested from the storage tank. Then, the cover 2 is placed on the barrel 1, making the cavity of the barrel 1 relatively sealed. Specifically, the material to be tested from the storage tank can be filled into the cavity of the barrel 1 by inserting a pipe into the opening at the top of the barrel 1. After the test is completed, the operator places the sealed sampling barrel containing the material on one side of the pump body and connects the exhaust valve 4 to the input end of the pump body. The pump body is then started. During operation, the pump body uses turbine pressure to extract the tested material from the cavity of the barrel 1. During the above process, the exhaust valve 3 is used for air intake to maintain the pressure balance inside the barrel 1 until all the material in the cavity of the barrel 1 is extracted. The operator then turns off the pump body and locks the exhaust valve 3 and the exhaust valve 4.

[0040] In the above process, since the material is in a sealed state for most of the transportation of the material in the barrel 1, the safety is significantly improved and the problem of VOC emission is avoided. Especially in the subsequent process of recycling the material in the barrel 1 to the storage tank, in this embodiment, it is only necessary to connect the drain valve 4 to the pump body and use pipeline transportation to achieve the complete recycling of the material, avoiding the need for manual handling in the prior art, thus avoiding the potential safety problems and solving the material recycling problem at a relatively low cost.

[0041] Furthermore, the sealed sampling container also includes a locking cap 5, which comprises a locking cap 51 and a locking buckle 52. The locking cap 51 is located on the edge of the cover 2, and the locking buckle 52 is located on the edge of the opening of the container 1. The locking cap 51 and the locking buckle 52 are positioned to match each other. The locking buckle 52 can be rotated and hooked onto the locking cap 51. The locking cap 5 is used to press and fix the cover 2 onto the container 1. In this embodiment, by means of the mechanical connection between the locking cap 51 and the locking buckle 52, the sealing problem between the container 1 and the cover 2 can be solved quickly, conveniently, and stably.

[0042] In the above embodiment, there are four locking buckles 5, which are spaced apart at quadrant points on the barrel 1 and the lid 2. This embodiment takes into account the general dimensions of the lid 2, as well as operational efficiency and structural cost, and represents a better solution while meeting sealing performance requirements.

[0043] Furthermore, the vent valve 3 is located on the top surface of the cover 2, and is positioned near the edge of the cover 2. The vent valve 3 is configured as a U-shaped bend with its second end bent downwards. Specifically, the downward-bent U-shaped bend prevents external debris from entering the cavity of the container 1, and especially prevents liquid from dripping into the container 1 along the edge.

[0044] Furthermore, the drain valve 4 is installed on the vertical side wall of the barrel 1 and is located near the bottom of the barrel 1. The drain valve 4 is mainly used to drain the fluid in the cavity of the barrel 1. Therefore, setting a lower liquid level can help avoid the sedimentation of the material at the bottom.

[0045] Specifically, in this embodiment, the size of the exhaust valve 3 is set to 0.5 inches, and the size of the exhaust valve 4 is set to 1 inch. The larger size of the exhaust valve 4 takes into account the fluid resistance of the material, while the smaller size of the exhaust valve 4 prevents external foreign objects from falling in.

[0046] In another embodiment, the sealed sampling container also includes a handle 6, which is disposed on the vertical side wall of the container body 1 and located near the top of the container body 1. Specifically, the main function of the handle 6 is to facilitate the operator to quickly move the entire sealed sampling container, thereby improving operational efficiency.

[0047] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0048] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0049] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
