Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to a nitrogen blowing component applied to a nitrogen blowing concentration device. Background Technology

[0002] Nitrogen blowing concentration devices are commonly used laboratory equipment that accelerates solvent evaporation by blowing nitrogen gas to concentrate or bring samples to a fixed volume. They are widely used in environmental monitoring, drug analysis, food testing and other fields.

[0003] A search of Chinese patent CN 220289175 U reveals a nitrogen blowing assembly, comprising a mounting frame with a circular plate inside. Four storage frames are fixedly connected to the top of the circular plate, and a rotating structure is located at the bottom of the plate. A nitrogen blowing structure is mounted on the mounting frame, comprising a gas storage tank, a first rigid pipe, an air pump, a second rigid pipe, a flexible hose, and a nozzle. The gas storage tank is fixedly mounted on one side of the mounting frame, and the bottom end of the first rigid pipe is fixedly connected to the gas storage tank. This invention uses a motor to drive a rotating shaft, which in turn rotates the four storage frames, positioning multiple test tubes at the bottom of the nozzle. The air pump draws nitrogen from the gas storage tank through the first rigid pipe, and the nozzle discharges the nitrogen downwards. Similarly, the circular plate moves one storage frame away from the nozzle and another closer to it, removing multiple test tubes from one of the frames. This cycle repeats, resulting in high nitrogen blowing efficiency and good performance.

[0004] In existing technology, a hydraulic cylinder extends to move one of the side plates downward, thereby moving the nozzle downward. Similarly, the hydraulic cylinder retracts to move the nozzle upward, allowing the nozzle height to be adjusted as needed. However, this technology can only adjust the vertical height of the nozzle and cannot adjust its tilt accordingly. As a result, it is difficult to adapt to tilted or irregularly shaped containers, reducing the adaptability of the device. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a nitrogen blowing assembly for use in a nitrogen blowing concentration device, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution: This utility model relates to a nitrogen blowing assembly used in a nitrogen blowing concentration device, comprising: Acceptance plate; A multi-angle adjustment assembly includes a first circular groove, a sphere, a gas guide tube, a nitrogen blowing needle, a hose, a limiting plate, and a second circular groove. The first circular groove is formed through the receiving plate, and the sphere is movably connected in the first circular groove. The gas guide tube is fixedly inserted into the middle of the sphere, and the nitrogen blowing needle is fixedly connected to the bottom of the gas guide tube. One end of the hose is fixedly connected to the top of the gas guide tube. A limiting plate is provided on the top of the receiving plate, and the second circular groove is formed through the limiting plate, in which the sphere is movably connected.

[0006] Furthermore, the multi-angle adjustment component also includes a rectangular block, a slot, a locking block, and a small hydraulic telescopic device. The rectangular block is fixedly connected to the side of the limiting plate, and the slot is opened vertically through the rectangular block. The small hydraulic telescopic device is fixedly connected to the top of the receiving plate, and the locking block is fixedly connected to the top of the small hydraulic telescopic device. The locking block is movably engaged in the slot.

[0007] Furthermore, the multi-angle adjustment assembly also includes a guide groove and a guide rod. The guide groove is formed through the receiving plate, and the guide rod is fixedly connected to the four corners of the bottom of the limiting plate. The guide rod is movably connected in the guide groove.

[0008] Furthermore, the multi-angle adjustment assembly also includes a receiving plate and a large hydraulic expansion joint, with the receiving plate fixedly connected to the side of the receiving plate and the large hydraulic expansion joint fixedly connected to the top of the receiving plate.

[0009] Furthermore, the number of the first circular groove and the sphere are both four.

[0010] Furthermore, it also includes a convenient cleaning component, which includes a first locking groove, a second locking groove, and a T-shaped locking rod. The rectangular block has a first locking groove extending through it in the horizontal direction, and the locking block has a second locking groove extending through it in the horizontal direction. The T-shaped locking rod is movably connected between the first locking groove and the second locking groove.

[0011] Furthermore, the easy-cleaning component also includes an anti-detachment groove and an L-shaped anti-detachment rod. The T-shaped locking rod has an anti-detachment groove, and the L-shaped anti-detachment rod is movably connected in the anti-detachment groove.

[0012] This utility model has the following beneficial effects: This invention allows the opening of a small hydraulic telescopic device to push the limiting plate upwards and disengage it from the sphere. At this time, rotating the air guide needle tube causes the sphere to rotate in the first circular groove, thereby achieving the tilt adjustment of the nitrogen blowing needle angle. Subsequently, closing the small hydraulic telescopic device causes the limiting plate to move downwards and cooperate with the receiving plate to clamp and limit the sphere, thus achieving the fixation of the nitrogen blowing needle after tilt adjustment. This enables oblique blowing on tilted or irregularly shaped containers, improving the overall adaptability of the device.

[0013] Based on the aforementioned beneficial effects, by removing the L-shaped anti-detachment rod from the anti-detachment groove, and then removing the T-shaped locking rod from the first locking groove and the second locking groove, the guide rod and the limiting plate can be separated from the receiving plate. This allows the sphere, along with the air guide tube and the nitrogen blowing needle, to be removed from the receiving plate, facilitating deep cleaning, maintenance, and replacement of the air guide tube and the nitrogen blowing needle.

The setting of the sphere 202 provides a guarantee for the rotation of the gas guide needle tube 203 and the nitrogen blowing needle 204. The end of the hose 205 is connected to the nitrogen generator to supply nitrogen. The limiting plate 206 provides a guarantee for the pressing limit of the sphere 202 after adjustment. The setting of the second circular groove 207 can ensure that the limiting plate 206 and the sphere 202 have sufficient contact area.

[0020] The multi-angle adjustment assembly also includes a rectangular block 208, a slot 209, a locking block 2010, and a small hydraulic expansion joint 2011. The rectangular block 208 is fixedly connected to the side of the limiting plate 206. The slot 209 is opened through the rectangular block 208 in the vertical direction. The small hydraulic expansion joint 2011 is fixedly connected to the top of the receiving plate 101. The locking block 2010 is fixedly connected to the top of the small hydraulic expansion joint 2011. The locking block 2010 is movably engaged in the slot 209. The rectangular block 208 provides a guarantee for the opening of the slot 209. The slot 209 and the block 2010 work together to ensure the initial connection of the small hydraulic expansion joint 2011 to the rectangular block 208. The small hydraulic expansion joint 2011 is model HSG10, which provides kinetic energy for the up and down movement of the limit plate 206.

[0021] The multi-angle adjustment assembly also includes a guide groove 2012 and a guide rod 2013. The guide groove 2012 is opened through the receiving plate 101. The guide rod 2013 is fixedly connected to the four corners of the bottom of the limiting plate 206. The guide rod 2013 is movably connected in the guide groove 2012.

[0022] The multi-angle adjustment assembly also includes a receiving plate 2014 and a large hydraulic expansion joint 2015. The receiving plate 2014 is fixedly connected to the side of the receiving plate 101, and the large hydraulic expansion joint 2015 is fixedly connected to the top of the receiving plate 2014. The installation of the receiving plate 2014 ensures the installation of the large hydraulic expansion joint 2015, model XG-275, and provides a guarantee for the vertical height adjustment of the nitrogen blowing needle 204.

[0023] The number of the first circular groove 201 and the sphere 202 are both four; The quantity of the above-mentioned components ensures the connection of an equal number of gas delivery needles 203, nitrogen blowing needles 204, and hoses 205, thereby enabling simultaneous operation on multiple groups of reagents.

[0024] Working principle: When the test tube containing the sample liquid is a standard straight test tube, it is placed on the mounting rack. Then, the large hydraulic expansion joint 2015 is opened. Under the action of the receiving plate 2014, the receiving plate 101 is driven to adjust its height, thereby adjusting the height of the nitrogen blowing needle 204. When the nitrogen blowing needle 204 moves to the appropriate height, the large hydraulic expansion joint 2015 is closed, and the nitrogen generator connected to the hose 205 is opened. Then, nitrogen gas is applied to the sample liquid through the hose 205, the gas guide needle 203, and the nitrogen blowing needle 204. If the test tube containing the sample liquid is an inclined or irregularly shaped container, it is first fixed on the mounting rack, and then the small hydraulic expansion joint is opened. Device 2011, under the action of rectangular block 208, drives the limiting plate 206 upward to disengage from the sphere 202. At this time, guide rod 2013 moves in guide groove 2012, and then rotates air needle tube 203, driving sphere 202 to rotate in first circular groove 201, driving nitrogen blowing needle 204 to rotate. When the angle of nitrogen blowing needle 204 is adjusted to be consistent with the angle of the inlet end of the inclined or irregularly shaped container, then the small hydraulic expansion joint 2011 is closed, driving the limiting plate 206 downward to achieve clamping and limiting fixation of sphere 202. Then the large hydraulic expansion joint 2015 is opened, driving nitrogen blowing needle 204 to move to a suitable height, and the above nitrogen blowing process is repeated.

[0025] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The easy-to-clean component includes a first locking groove 301, a second locking groove 302, and a T-shaped locking rod 303.

The T-shaped locking rod 303 is movably connected between the first locking groove 301 and the second locking groove 302. The first locking groove 301, the second locking groove 302, and the T-shaped locking rod 303 work together to ensure the initial locking connection between the rectangular block 208 and the locking block 2010.

[0026] The easy-to-clean components also include an anti-detachment groove 304 and an L-shaped anti-detachment rod 305. The T-shaped locking rod 303 has an anti-detachment groove 304, and the L-shaped anti-detachment rod 305 is movably connected in the anti-detachment groove 304. The anti-detachment groove 304 and the L-shaped anti-detachment rod 305 are used together to further increase the firmness of the connection between the rectangular block 208 and the locking block 2010, preventing the parts from detaching during operation.

[0027] Working principle: Remove the L-shaped anti-detachment rod 305 from the anti-detachment groove 304, then remove the T-shaped locking rod 303 from the first locking groove 301 and the second locking groove 302, then lift the limiting plate 206 together with the guide rod 2013 to detach from the receiving plate 101, and then remove the sphere 202 from the first circular groove 201, so that the air guide needle tube 203 and nitrogen blowing needle 204 can be separated from the receiving plate 101, which is convenient for deep cleaning and maintenance replacement.
