Description

Technical Field

[0001] The present application relates to the technical field of sample bottle buffer devices, and in particular to a sample bottle buffer device. Background Art

[0002] In the coal-fired industry, pneumatic conveying systems are essential for transporting coal samples throughout the collection, preparation, and testing process. Sample bottles are transported at high speed through pneumatic pipelines, following a designated path to a designated workstation. However, upon arrival at the receiving workstation, a sample buffer is required to slow the high-speed movement of the sample bottles and ensure they reach the workstation slowly and smoothly.

[0003] Currently, sample bottle buffering methods in pneumatic conveying systems include spring buffering, interception buffering, curved pipe gravity buffering, backpressure buffering, and high-pressure wind speed adjustment buffering. These buffering methods vary in effectiveness. Interceptor buffering is ineffective; curved pipe gravity buffering is effective but occupies a large space; existing backpressure buffering methods have many limitations and place high demands on coal sample bottles and piping; and high-pressure wind speed adjustment buffering methods are difficult to control. Inadequate buffering can damage coal sample bottles. Therefore, a buffering device with a strong buffering effect and minimal damage to coal sample bottles is needed. Utility Model Content

[0004] In order to improve the buffering effect of the existing buffer device and the problem of minimizing damage to the coal sample bottle, the present application provides a sample bottle buffer device.

[0005] The sample bottle buffer device provided in this application adopts the following technical solution:

[0006] A sample bottle buffer device, comprising:

[0007] The buffer tube is used to carry the coal sample bottle, and the inner wall of the buffer tube is adapted to the outer wall of the coal sample bottle;

[0008] A bottom platform is provided at the bottom of the buffer tube and has a bottle opening therethrough which is in communication with the bottom of the buffer tube;

[0009] A base is slidably disposed in the bottom platform, wherein a first station and a second station are provided in the bottom platform along the radial direction of the buffer tube. When the base slides to the first station, the buffer tube is directly connected to the bottle drop port; when the base slides to the second station, the base blocks the bottle drop port.

[0010] a buffer block, disposed in the base and adapted to slide airtightly with the buffer tube;

[0011] an air supply module, configured to pneumatically lift the buffer block in the base to the top of the buffer tube; and

[0012] A driving module is used to drive the base to switch between the first working position and the second working position.

[0013] Furthermore, the air supply module includes an air supply pipe connected to an external high-pressure air source, a solenoid valve is provided on the air supply pipe, and an accommodating groove for embedding the buffer block is provided on the upper end surface of the base, and the air supply pipe is connected to the accommodating groove.

[0014] Furthermore, the base is fixed with a middle protrusion at the middle of the bottom of the accommodating groove, and the middle of the lower end surface of the buffer block is provided with a middle groove that is plugged and adapted to the middle protrusion.

[0015] Furthermore, an air outlet connected to the air supply pipe is provided on the top of the middle convex block.

[0016] Furthermore, the driving mechanism includes a cylinder installed on the side wall of the base, and the piston rod of the cylinder is fixedly connected to the side wall of the base.

[0017] Furthermore, a bottle dropping sleeve is fixedly connected to one side of the base close to the cylinder, the inner diameter of the bottle dropping sleeve is not less than the diameter of the bottle dropping mouth, and the piston rod of the cylinder is fixedly connected to the bottle dropping sleeve.

[0018] Furthermore, a accommodating cavity for the base to slide is opened in the base platform, and when the base slides to the second working position, the base is airtightly connected to the upper cavity wall of the accommodating cavity.

[0019] Furthermore, when the buffer block is embedded in the accommodating groove, the upper end surface of the buffer block does not protrude from the upper end surface of the base.

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

[0021] 1. Before each coal sample bottle is transferred to the buffer tube via the pneumatic conveying pipeline, the drive module drives the base to the second station. The buffer block rises to the top of the buffer tube under the action of the air supply module, waiting for the arrival of the coal sample bottle. The coal sample bottle is transported at high speed in the pneumatic conveying pipeline. When the coal sample bottle is transferred to the buffer block, the buffer block moves downward along the buffer tube under the impact of the coal sample bottle. At this time, a very small back pressure space is formed between the buffer block, the buffer tube, and the base at the exhaust outlet. The existence of the back pressure space reduces the speed of the coal sample bottle, which can achieve a good buffering effect and minimize damage to the coal sample bottle.

[0022] 2. After the coal sample bottle and the buffer block fall into the base, the base switches positions under the control of the drive module, switching from the second position to the first position. After the switch, a passage is formed between the buffer tube and the base, ensuring an unobstructed drop opening. Gravity then allows the coal sample bottle to fall directly to the receiving station or other receiving platform below, ensuring smooth receipt. When the coal sample bottle is removed, the base switches to the second position again under the control of the drive module. The air supply module then lifts the buffer block again, awaiting the arrival of the next coal sample bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 , the embodiment of the present application discloses a sample bottle buffer device, which includes:

[0038] The buffer tube 1 is used to carry the coal sample bottle 7, and the inner wall thereof is adapted to the gap between the outer wall of the coal sample bottle 7. The top of the buffer tube 1 is connected to the pneumatic conveying pipe of the coal sample bottle 7;

[0039] The base 2 is provided at the bottom of the buffer tube 1 and has a bottle drop opening 21 extending therethrough and corresponding to the bottom of the buffer tube 1. The diameter of the bottle drop opening is larger than the maximum outer diameter of the coal sample bottle 7.

[0040] The base 3 is slidably disposed in the bottom platform 2. A first station 22 and a second station 23 are provided in the bottom platform 2 along the radial direction of the buffer tube 1. When the base 3 slides to the first station 22, the buffer tube 1 is directly connected to the bottle drop port; when the base 3 slides to the second station 23, the base 3 blocks the bottle drop port.

[0041] The buffer block 4 is provided in the base 3 and is airtightly slidably adapted to the buffer tube 1. When the base 3 slides to the second station 23, the buffer block 4 is aligned with the tube punch;

[0042] An air supply module, used to pneumatically lift the buffer block 4 in the base 3 to the top of the buffer tube 1; and

[0043] The driving module is used to drive the base 3 to switch between the first station 22 and the second station 23.

[0044] With this setup, before each coal sample bottle is transported through the pneumatic conveying pipeline to the buffer tube 1, the drive module drives the base 3 into the second station 23. The buffer block 4, under the action of the air supply module, rises to the top of the buffer tube 1, awaiting the arrival of the coal sample bottle. The coal sample bottle is transported at high speed in the pneumatic conveying pipeline. When the coal sample bottle 7 is transferred to the buffer block 4, the buffer block 4 moves downward along the buffer tube 1 under the impact of the coal sample bottle. At this time, a minimal backpressure space is formed between the buffer block 4, the buffer tube 1, and the base 3, creating a backpressure space at the exhaust outlet. This backpressure space reduces the speed of the coal sample bottle, providing a good buffering effect and minimizing damage to the coal sample bottle 7.

[0045] After the coal sample bottle falls into the base 3 along with the buffer block 4, the base 3 switches its position under the action of the drive module, switching from the second position 23 to the first position 22. After the position switch, a passage is formed between the buffer tube 1 and the base 3, leaving the bottle drop port unobstructed. Gravity now allows the coal sample bottle to fall directly to the receiving station or other receiving platform below, ensuring smooth receipt. When the coal sample bottle is removed, the base 3 again switches to the second position 23 under the action of the drive module; the air supply module repeatedly lifts the buffer block 4, awaiting the arrival of the next coal sample bottle.

[0046] Specifically, refer to Figure 1 、 Figure 2 and Figure 4 The air supply module includes an air supply pipe 51 connected to an external high-pressure air source, and an electromagnetic valve 52 is provided on the air supply pipe 51. A receiving groove 31 for the buffer block 4 to be embedded is provided on the upper end surface of the base 3, and the air supply pipe 51 is connected to the receiving groove 31; and a middle protrusion 32 is fixedly connected to the middle part of the bottom wall of the receiving groove 31 of the base 3, and a middle groove 41 is provided in the middle part of the lower end surface of the buffer block 4, which is plugged and adapted to the gap of the middle protrusion 32, and an air outlet 321 connected to the air supply pipe 51 is provided on the top of the middle protrusion 32.

[0047] After this setting, when the base 3 moves to the second workstation 23, the buffer block 4 in the base 3 is aligned with the buffer tube 1. At this time, the solenoid valve 52 opens, and the external compressed air is transported to the middle protrusion 32 in the accommodating groove 31 through the air supply pipe 51 and ejected through the air outlet 321, which can steadily lift the buffer block 4 to the top of the buffer tube 1.

[0048] In addition, refer to Figure 1 and Figure 3 The driving mechanism includes a cylinder 61 installed on the side wall of the base 2. The piston rod of the cylinder 61 is arranged along the arrangement direction of the first workstation 22 and the second workstation 23. The piston rod of the cylinder 61 is fixedly connected to the side wall of the base 3. A bottle-dropping sleeve 62 is fixedly connected to the side of the base 3 close to the cylinder 61. The inner diameter of the bottle-dropping sleeve 62 is not less than the diameter of the bottle-dropping mouth. The piston rod of the cylinder 61 is fixedly connected to the bottle-dropping sleeve 62.

[0049] In this way, when the cylinder 61 pushes the bottle-dropping sleeve 62 to drive the base 3 to move horizontally, the base 3 enters the first station 22 from the second station 23. At this time, the bottle-dropping sleeve 62 is aligned with the bottle-dropping mouth, and the buffered coal sample bottle 7 in the buffer tube 1 can fall freely through the bottle-dropping mouth and the bottle-dropping sleeve 62 without interfering with the normal falling of the coal sample bottle 7; when the cylinder 61 pulls the bottle-dropping sleeve 62 to drive the base 3 to move horizontally, the base 3 enters the second station 23 from the first station 22. At this time, the base 3 blocks the bottle-dropping mouth, and the buffer block 4 can enter the ready state.

[0050] In addition, a accommodating cavity 24 for the base 3 to slide is opened in the base 2. When the base 3 slides to the second workstation 23, the base 3 is airtightly connected to the upper cavity wall of the accommodating cavity 24. When the buffer block 4 is embedded in the accommodating groove 31, the upper end surface of the buffer block 4 does not protrude from the upper end surface of the base 3.

[0051] The implementation principle of a sample bottle buffer device in the embodiment of the present application is as follows:

[0052] Before each coal sample bottle is transported through the pneumatic conveying pipeline to the buffer tube 1, the drive module drives the base 3 into the second station 23. The buffer block 4, under the action of the air supply module, rises to the top of the buffer tube 1, awaiting the arrival of the coal sample bottle. The coal sample bottle is transported at high speed in the pneumatic conveying pipeline. When the coal sample bottle 7 is transferred to the buffer block 4, the buffer block 4 moves downward along the buffer tube 1 under the impact of the coal sample bottle. At this time, a minimal backpressure space is formed between the buffer block 4, the buffer tube 1, and the base 3, which reduces the speed of the coal sample bottle, providing a good buffering effect and minimizing damage to the coal sample bottle 7.

[0053] After the coal sample bottle falls into the base 3 along with the buffer block 4, the base 3 switches its position under the action of the drive module, switching from the second position 23 to the first position 22. After the position switch, a passage is formed between the buffer tube 1 and the base 3, leaving the bottle drop port unobstructed. Gravity now allows the coal sample bottle to fall directly to the receiving station or other receiving platform below, ensuring smooth receipt. When the coal sample bottle is removed, the base 3 again switches to the second position 23 under the action of the drive module; the air supply module repeatedly lifts the buffer block 4, awaiting the arrival of the next coal sample bottle.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
