Technical Field
The invention relates to a device for removing solid particles in a container, in particular to a device for removing the solid particles in the container in the pretreatment process of a sample in a laboratory, and especially for removing the sample in an extraction tank after rapid solvent extraction.
Background
During pre-processing, the container is typically filled with solid particles, the type of which includes various adsorbents or solid, semi-solid samples. When the container needs to be reused, the original sample in the container needs to be removed, and the type of the container comprises various materials such as metal, plastic, glass and the like.
The conventional method is to make the solid flow out by knocking and other methods, and the process is time-consuming and labor-consuming, and can also damage the original appearance or precision of the container, and in serious cases, the container can be damaged and cannot be used again.
Taking the container used in the high-efficiency pressure solvent extractor (or called fast solvent extractor) as an example, the container is generally called an extraction tank or an extraction cell, and the container is made of 316L metal and needs to be reused. In practical application, the container is used for containing a solid or semisolid sample, the container is placed into a high-efficiency pressure solvent extraction instrument, then the container is heated at high temperature and injected with high-pressure solvent to extract organic matters in the sample, and the sample in the extraction tank needs to be removed after an experiment is finished.
When sample particles in a container are removed by a traditional method, the sample is required to be knocked to enable the sample to have fluidity, the appearance, the sealing surface, the connecting structure (usually threads) and the like of the container are easily damaged in the knocking process, so that the container cannot be reused (the container is usually sold in thousands of RMB bills, and the like), and meanwhile, the problem that the treatment process is slightly long (about 2-3 minutes is needed) exists.
Disclosure of Invention
The object of the invention is to provide a device for removing solid particles from a container, i.e. to press out the solid particles from the container by means of compressed air according to the principle of air resistance, without damaging the container and with a reduced processing time.
In order to achieve the purpose, the invention adopts the technical scheme that:
an apparatus for removing solid particles from a container, the container having openings at opposite ends, the apparatus comprising: the device is provided with a body, an air passage is arranged in the body, the head end of the body is a gas inlet joint and used for providing pressure gas for the air passage, and the tail end of the body is provided with a spray hole and used for guiding and spraying the pressure gas in the air passage outwards; and a sealing ring is arranged on the outer ring side of the tail end of the body and can form sealing connection with the inner wall of the opening at one end of the container.
The apparatus for removing solid particles from a vessel, wherein: and a retaining ring is arranged on the outer ring side of the tail end of the body and used for protecting the sealing ring.
The apparatus for removing solid particles from a vessel, wherein: a nut is threadably connected to the body end for securing the retaining ring and the seal ring.
The apparatus for removing solid particles from a vessel, wherein: the gas inlet joint is connected with the body in a threaded, welded, clamped, glued or tight-fit connection mode.
The apparatus for removing solid particles from a vessel, wherein: the gas pressure control device is characterized by further comprising a control valve capable of controlling the on-off of pressure gas, wherein the control valve is arranged on the body or the gas inlet joint, or on an inlet pipeline connected with the gas inlet joint, or on a pressure gas source for providing pressure gas for the gas inlet joint.
The apparatus for removing solid particles from a vessel, wherein: the vessel is an extraction tank.
Compared with the prior mode of removing solid particles in the container, the invention has the following advantages:
(1) the device for removing solid particles in the container solves the problem of long time consumption in the original mode.
(2) The invention solves the problem that the original mode is easy to damage the container.
(3) The invention can save the experiment time and reduce the personnel cost in the experiment.

Detailed Description
As shown in fig. 1, the present invention provides an apparatus for removing solid particles from a container, which comprises a body 1, a gas channel 10 is provided in the body 1, a gas inlet joint 5 is provided at the head end of the body 1 for providing pressure gas to the gas channel 10, and a nozzle 11 is provided at the tail end of the body 1 for guiding the pressure gas in the gas channel 10 outwards; the outer ring side of the tail end of the body 1 is also provided with a retaining ring 2 and a sealing ring 3, and a nut 4 is connected to the tail end of the body 1 through threads and used for fixing the retaining ring 2 and the sealing ring 3 without falling off.
The gas inlet joint 5 is preferably connected with the body 1 by threads, and can be connected with the body 1 by other connection modes such as welding, clamping, gluing and tight fit connection.
In order to control the on-off of the pressure gas, a control valve 6 can be arranged on the body 1, and the pressure gas can be blocked or released from entering the spray hole 11 by operating the control valve 6; of course, the control valve 6 may also be provided on the gas inlet connection 5, on an inlet line connected to the gas inlet connection 5, or even on a pressurized gas source providing pressurized gas to the gas inlet connection 5. The specific form and model of the control valve 6 are not limited herein, and commercially available products can be selected, and the installation and adjustment of the control valve 6 are not important in the present invention, and therefore, the drawings are also simplified, and should not affect the implementation of the technical solution by those skilled in the art.
Referring to fig. 2, the working status of the present invention is schematically illustrated, when the present invention is used, the tail end of the apparatus 100 is directly plugged into an opening at one end of the extraction tank 200, the sealing ring 3 is tightly connected to the inner wall of the opening of the extraction tank 200, and then the supply of the pressure gas (including opening the control valve 6) is opened, so that the pressure gas is ejected into the extraction tank 200 at a high speed through the nozzle 11 of the gas channel 10, and the sample 204 in the extraction tank 200 is blown out of the extraction tank 200.
The present invention uses pneumatic force to remove the sample 204 (fixed particles) in the extraction tank 200, so that the solid particles in the container can be removed quickly (several seconds, tens of seconds) without damaging the container.
In addition, the retaining ring 2 of the present invention functions as: in the long-time use process, the damage or the service life reduction of the sealing ring 3 caused by improper operation is prevented, namely the sealing ring 3 is protected, and the invention can still normally work and use under the condition that the retaining ring 2 is removed.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
