Problems solved by technology

The staff needs to design the material to be transported according to the size of the pipeline, or design the pipeline according to the size of the sample bottle. There are problems such as difficult processing of pipes and sample bottles, high cost of use, and very inconvenient operation.
[0006] (2) This transportation method has low safety and poor compatibility
Due to the high matching requirements of sample bottles and pipelines, the operator cannot realize the delivery of various specifications of sample bottles in the same delivery pipeline.
At the same time, this method has no protection for the sample bottle, and the high air pressure directly acts on the sample bottle to push the sample bottle forward, which may easily cause serious consequences such as sample bottle rupture or even sample bottle explosion.
[0007] (3) Vials are prone to stuck during transportation in this way
Because this method uses the sample bottle and the pipeline to match, when the sample bottle is deformed or damaged, it is easy to cause the sample bottle to be stuck during the transmission process, which affects the transmission efficiency and high maintenance costs
At the same time, due to the long-term contact and friction between the sample bottle and the pipeline, it is easy to cause wear and tear on the pipeline, and the pipeline needs to be replaced irregularly, resulting in high usage costs.
[0008] (4) In this mode of transportation, the sample bottle directly rubs against the pipeline, and the frictional heat during high-speed transmission (10 meters per second) will cause the sample water in the sample bottle to be analyzed or oxidized, affecting the physical characteristics and accuracy of the sample

specific Embodiment 1

[0050] Specific embodiment 1: as image 3 As shown, in a preferred embodiment, the axial end surface of the piston sheath 4 is provided with a fixing portion 41 for fixing the object 3 to be conveyed. By arranging the fixing part 41, the piston sheath 4 can be arranged behind the object 3 to be conveyed for pushing the object 3 to be conveyed, and the piston sheath 4 can be arranged in front of the object 3 for conveying. Pulling the object to be conveyed 3 realizes the conveyance; by cooperating with the driving air source unit 2 capable of generating positive / negative air pressure in the conveying pipeline unit 1, the pneumatic conveying methods of the present invention are varied and flexible. In this preferred embodiment, the fixing part 41 includes a concave bracket arranged on the end surface of the piston sheath 4, and the object to be transported 3 such as figure 1 As shown, one end of it is clamped and fixed in the concave bracket.

[0051] Such a special design has...

specific Embodiment 2

[0052] Specific embodiment 2: as Figure 4 As shown, the fixed portion 41 includes a recessed protection cavity 44 arranged on one end of the piston sheath 4, the protection cavity 44 is used to carry the object to be conveyed 3 so that the object to be conveyed 3 does not contact the transmission pipeline unit 1, and the opening of the protection cavity 44 A matching guide part 45 is provided at the end. When the piston sheath 4 pushes the object 3 to be conveyed, the guide part 45 first contacts the object 3 to be conveyed and guides the object 3 to be conveyed into the protection cavity 44 under the action of thrust.

[0053] Through such an arrangement, there are the following advantages: First, because the object 3 to be conveyed is carried on the protection cavity 44 and does not contact the transmission pipeline unit 1, the piston sheath 4 forms a more comprehensive protection for the object 3 to be conveyed, further ensuring that the air pressure does not It will direc...

specific Embodiment 3

[0059] Specific embodiment 3: as Figure 5As shown, in this preferred embodiment, the axial ends of the piston sheath 4 are symmetrically tapered, so that the overall shape of the piston sheath 4 is a drum shape with thin ends and a thick middle, so that when the piston sheath 4 is stationary, Contact with the transfer pipe unit 1 is maintained only through the axial middle. Through such a special scientific design, first, the contact surface between the piston sheath 4 and the transmission pipeline unit 1 is small, reducing the friction between the piston sheath 4 and the transmission pipeline, and the transmission resistance is small; second, this special structure makes the piston sheath 4 4. During the high-speed pneumatic conveying in the conveying pipe unit 1, it can flexibly adapt to the direction of the pipe, and effectively prevent the piston sheath 4 from turning over and being stuck.

Abstract

The invention discloses a pneumatic material conveying system capable of driving by utilizing a single piston sheath. The pneumatic material conveying system comprises a transmission pipeline unit and a driving air source unit, wherein the transmission pipeline unit is internally provided with a material to be conveyed; the driving air source unit is communicated with the transmission pipeline unit, so that positive / negative air pressure is generated in the transmission pipeline unit; the transmission pipeline unit is also internally provided with the piston sheath matched with a transmission pipeline; the axial end of the piston sheath is in contact with the material to be conveyed; the piston sheath makes movement in the transmission pipeline unit under the action of the driving air source unit so as to complete the pneumatic conveying of the material to be conveyed. The pneumatic material conveying system has the advantages of being good in compatibility, low in use cost, convenient and fast in delivery and high in safety, and being capable of guaranteeing the physical properties and accuracy of a sample.

Description

technical field [0001] The invention mainly relates to the field of equipment for collecting and processing material samples, in particular to a material pneumatic conveying system driven by a single-piston sheath. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis ...
