Description

Technical Field

[0001] This application relates to the field of sample delivery technology, and in particular to a coal sample bottle gas delivery chamber. Background Technology

[0002] Coal sample bottles are containers used to store coal samples. They are typically made of chemically resistant materials to maintain the purity and integrity of the samples. As the container for the coal samples, they are transported in pipelines using pneumatic transfer at the sample preparation and testing receiving points. Pneumatic transfer is widely used in fields such as hospital drug delivery and coal quality analysis due to its advantages of high efficiency, energy saving, and unmanned operation.

[0003] In a pneumatic transfer system, the pipeline serves as the track for the pneumatic transport of coal sample bottles, making it the most crucial component of the entire system. Pneumatic transfer pipelines typically range from tens to hundreds of meters in length. Such long transport distances demand high precision in pipeline manufacturing and installation. Pipeline misalignment is unavoidable, but it is a major cause of bottle cap detachment and coal sample loss. Furthermore, despite national standards, the dimensions of coal sample bottles vary between manufacturers. Integrating equipment from different manufacturers not only requires laying new pneumatic delivery pipelines but also incurs relatively high costs for modifying and constructing supporting equipment.

[0004] Furthermore, the screw-on cap structure of the coal sample loading bottle in the existing pneumatic transmission system makes it easy for the cap to be scraped off by the misalignment of the pipeline in the air delivery pipeline, resulting in the loss of coal sample. Utility Model Content

[0005] In order to improve the problem that coal sample bottles are prone to loss during gas delivery and that different sizes affect the delivery efficiency of gas delivery pipelines, this application provides a coal sample bottle gas delivery carrier.

[0006] The technical solution for the gas delivery chamber for coal sample cylinders provided in this application is as follows:

[0007] A coal sample cylinder gas delivery chamber includes:

[0008] The upper cabin has an opening at one end;

[0009] The lower compartment has an opening at one end, and the opening end of the upper compartment is detachably connected to the opening end of the lower compartment.

[0010] Two sealing strips are provided and fixed to the outer peripheral walls of the upper and lower compartments respectively, and their outer diameters are larger than the outer diameter of the upper compartment; and

[0011] A support frame is installed on the bottom wall of the lower compartment to support coal sample bottles of different sizes.

[0012] Furthermore, the support frame includes multiple annular support platforms parallel to the bottom wall of the lower compartment and connecting pieces for connecting two adjacent support platforms. The multiple support platforms are spaced apart along the axial direction of the lower compartment, and the outer diameter of the support platform closer to the central axis of the lower compartment is smaller than the inner diameter of the other support platform.

[0013] After the upper compartment and the lower compartment are fully connected, the distance between the support platform and the inner top wall of the upper compartment is adapted to the length of the specified coal sample bottle.

[0014] Furthermore, the end of the connecting piece near the lower compartment opening is configured to flare outwards.

[0015] Furthermore, a sealing gasket is provided on the top wall of the upper compartment.

[0016] Furthermore, both the upper and lower compartments have protrusions on their outer peripheral walls at the ends furthest from their respective openings, and the sealing strip is fixed to the protrusions.

[0017] Furthermore, the top of the upper compartment or the bottom of the lower compartment is provided with a chip or data identifier for reading and writing codes.

[0018] Furthermore, the outer perimeter wall of the upper compartment and / or the lower compartment is provided with anti-slip texture.

[0019] Furthermore, the sealing strip is any one of felt, ribbon, wool strip, or high-slip fabric.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When transporting coal samples, the coal sample bottle is placed in the lower compartment. Depending on the size of the coal sample bottle, it can be placed on the corresponding support platform. Then, the upper compartment is screwed onto the lower compartment. At this time, the coal sample bottle is locked between the support platform and the top wall of the upper compartment, which can fix the coal sample bottle. This allows the carrying compartment to be well adapted to the carrying and fixing of coal sample bottles of various specifications. It can realize the pneumatic transport of coal sample bottles from different manufacturers, with strong applicability and can greatly reduce the modification and construction costs of pneumatic pipelines.

[0022] 2. During the process of transporting coal samples in the pneumatic pipeline, the connection between the upper and lower compartments is located in the middle of the coal sample delivery bin. This prevents the coal sample delivery bin from falling off or being lost when passing through the misaligned section of the pneumatic pipeline, thus ensuring the quality and quantity of coal sample delivery.

[0023] 3. Both the upper and lower compartments have protruding parts on their outer walls, which can create a waist-like structure in the middle of the delivery compartment, thus ensuring that the delivery compartment can pass through the bends in the gas delivery pipeline.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] Reference Figure 1 and Figure 2 This application discloses a coal sample bottle gas delivery chamber, which includes a detachably connected upper chamber 1 and lower chamber 2. When the upper chamber 1 and lower chamber 2 are closed together, they form a delivery chamber, creating a sealed cavity inside for placing coal samples or coal sample bottles. Specifically, both the upper chamber 1 and lower chamber 2 have an open end, and the open ends of the upper chamber 1 and lower chamber 2 are detachably connected. The connection method can be a threaded connection, a rotary snap-fit ​​connection, or a snap-fit ​​connection, as long as it achieves a tight connection between the two cylindrical bodies. In this embodiment, a simple and easy-to-implement threaded connection method is chosen.

[0032] Furthermore, sealing strips 3 are provided on the outer perimeter walls of both the upper compartment 1 and the lower compartment 2. The outer diameter of the sealing strip 3 is larger than that of the upper compartment 1. The sealing strip 3 can be any one of felt, ribbon, wool strip or high-slip fabric, in order to minimize the sliding resistance of the delivery bin in the air delivery channel and ensure the sealing of the delivery bin in the air delivery pipeline, so as to ensure the delivery pressure difference of the delivery bin in the air delivery pipeline.

[0033] Additionally, refer to Figure 2 The lower compartment 2 is also provided with a support frame 4 for supporting coal sample bottles of different sizes in the inner bottom wall. The support frame 4 includes multiple annular support platforms 41 parallel to the inner bottom wall of the lower compartment 2 and a connecting piece 42 for connecting two adjacent support platforms 41. The multiple support platforms 41 are arranged at intervals along the axial direction of the lower compartment 2. The outer diameter of the support platform 41 closer to the central axis of the lower compartment 2 is smaller than the inner diameter of the other support platform 41.

[0034] Furthermore, once the upper compartment 1 and the lower compartment 2 are fully connected, the distance between the support platform 41 and the inner top wall of the upper compartment 1 is adapted to the length of the specified coal sample bottle.

[0035] Thus, when transporting coal samples, the coal samples can be directly placed into the transport chamber consisting of the lower chamber 2 and the upper chamber 1, or the coal samples can be placed in coal sample bottles and then placed in the lower chamber 2. Depending on the size of the coal sample bottle, the coal sample bottle can be placed on the corresponding support platform 41, and then the upper chamber 1 can be screwed onto the lower chamber 2. At this time, the coal sample bottle is locked between the support platform 41 and the inner top wall of the upper chamber 1, which can form a fixation of the coal sample bottle. The connecting piece 42 can be used to connect the support platform 41 and strengthen the rigidity of the support platform 41, and can also limit the coal sample bottle to a certain extent in the circumferential direction, so as to reduce the probability of the coal sample bottle shaking in the transport chamber during the pneumatic transport process.

[0036] Specifically, such as Figure 3 As shown, when the loading chamber carries coal sample bottles of certain standard specifications, such as coal sample bottle 71 with a specification of φ100×300mm, coal sample bottle 72 with a specification of φ125×280mm, and coal sample bottle 73 with a specification of φ150×200mm, the upper ends of the coal sample bottles of different sizes are flush with the inner top wall of the upper chamber 1, and the lower ends abut against different bearing platforms. This allows the loading chamber to be well adapted to the carrying and fixing of coal sample bottles of various specifications, and can realize the pneumatic conveying of coal sample bottles from different manufacturers. It has strong applicability and can greatly reduce the modification and construction costs of pneumatic conveying pipelines.

[0037] Furthermore, during the process of transporting coal samples through the pneumatic pipeline, the connection between the upper compartment 1 and the lower compartment 2 is located in the middle of the coal sample transport compartment. This prevents the coal sample transport compartment from falling off or being lost when passing through the misaligned section of the pneumatic pipeline, thus ensuring the quality and quantity of coal sample transport.

[0038] Furthermore, referring to Figure 2 and Figure 3The upper compartment 1 has a sealing gasket 11 on its inner top wall. The sealing gasket 11 is made of rubber and can deform under pressure to ensure that coal sample bottles of various sizes can be tightly fixed. Even if the coal sample bottle is not tightened or has certain processing errors, the delivery compartment can still fit perfectly. The end of the connecting piece 42 near the opening of the lower compartment 2 is designed to flare outward to facilitate the insertion of the coal sample bottle into the smaller support platform 41.

[0039] Furthermore, refer to Figure 1 and Figure 2 Both the upper compartment 1 and the lower compartment 2 have an outwardly protruding part 51 on the outer peripheral wall of the end away from their respective openings, and a sealing strip 3 is fixed to the outer arc side of the outwardly protruding part 51. In this way, the two outwardly protruding parts 51 can form a waist-shaped structure in the middle of the delivery compartment, thereby ensuring that the delivery compartment can pass through the bend in the air delivery pipeline better; and when specifically setting up the upper compartment 1 and the lower compartment 2, it is only necessary to keep the outer diameter of the two outwardly protruding parts 51 consistent, and there is no requirement for the outer diameter of the upper compartment 1 and the lower compartment 2 to be consistent, which makes the structural design of the upper compartment 1 and the lower compartment 2 more flexible.

[0040] And as some adaptive settings, refer to Figure 1 and Figure 2 Anti-slip texture 52 is provided on the outer perimeter wall of the upper compartment 1 and / or the lower compartment 2 to facilitate the disassembly and assembly of the upper compartment 1 and the lower compartment 2.

[0041] Additionally, refer to Figure 1 and Figure 2 A chip 6 or data identifier for reading and writing codes is provided on the top of the upper compartment 1 or the bottom of the lower compartment 2. The chip 6 can be an NFC chip 6, a positioning chip 6, etc., and the data identifier can be a QR code, a barcode, etc. In this way, when the delivery compartment passes through the gas delivery pipeline, or after passing through, the delivered coal sample can be located or calibrated, which facilitates the numbering and collection of the coal sample during sampling.

[0042] The implementation principle of a coal sample bottle gas delivery chamber in this application embodiment is as follows:

[0043] When transporting coal samples, the coal samples can be directly placed into the transport chamber consisting of the lower chamber 2 and the upper chamber 1, or the coal samples can be placed in coal sample bottles and then placed in the lower chamber 2. Depending on the size of the coal sample bottle, the coal sample bottle can be placed on the corresponding support platform 41, and then the upper chamber 1 can be screwed onto the lower chamber 2. At this time, the coal sample bottle is locked between the support platform 41 and the inner top wall of the upper chamber 1, which can form a fixation of the coal sample bottle. This allows the transport chamber to be well adapted to the bearing and fixing of coal sample bottles of various specifications. It can realize the pneumatic transport of coal sample bottles from different manufacturers, with strong applicability and can greatly reduce the modification and construction costs of pneumatic transport pipelines.

[0044] Furthermore, during the process of transporting coal samples through the pneumatic pipeline, the connection between the upper compartment 1 and the lower compartment 2 is located in the middle of the coal sample transport compartment. This prevents the coal sample transport compartment from falling off or being lost when passing through the misaligned section of the pneumatic pipeline, thus ensuring the quality and quantity of coal sample transport.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
