Description

Technical Field

[0001] The utility model relates to the technical field of gas chromatographs, in particular to an air cooling structure of a gas chromatograph. Background Art

[0002] Gas chromatograph is an instrument that uses chromatographic separation and detection technology to perform qualitative and quantitative analysis on complex multi-component mixtures. It can usually be used to analyze organic matter in the soil that is thermally stable and has a boiling point not exceeding 500°C. During the operation of the gas chromatograph, auxiliary heat dissipation is required.

[0003] After searching, a Chinese patent (application number is "202320704496.5") discloses "a wind-cooling structure for a gas chromatograph". The wind-cooling structure includes a protective cover, a chromatograph is arranged on the inner side of the protective cover, a door panel is rotatably connected to the front side of the protective cover, fans are fixedly installed on the left and right sides of the protective cover, and the top of the protective cover is slidably connected to symmetrically arranged sliding racks. There are two sliding racks, and fixtures are fixedly installed on the inner sides of the two sliding racks. The fixtures cooperate with the protective cover and the gas chromatograph respectively. The control mechanism includes two sliding blocks, a connecting rod and a fixed rack. However, the wind-cooling structure has the following problems during use:

[0004] 1. When assisting the heat dissipation of the gas chromatograph, the moisture in the outside air is not separated, causing humid air to enter the gas chromatograph and causing the electrical components to become damp, resulting in low practicality;

[0005] 2. When auxiliary heat dissipation of the gas chromatograph is performed only through fans, hot air will gather around the gas chromatograph. When the internal heat dissipation structure of the gas chromatograph dissipates heat, the difference between the outside air temperature and the internal heat temperature is small, resulting in low heat dissipation efficiency of the gas chromatograph and poor auxiliary heat dissipation effect. Utility Model Content

[0006] The utility model provides an air cooling structure for a gas chromatograph, which solves the problem that the comparative document fails to separate the moisture in the outside air, causing humid air to enter the gas chromatograph and causing the electrical components to become damp, the practicability is low, the difference between the outside air temperature and the internal heat temperature is small, and the auxiliary heat dissipation effect is poor.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A wind cooling structure of a gas chromatograph comprises a gas-liquid separation mechanism arranged on one side of a gas chromatograph body, the gas-liquid separation mechanism comprises a mounting frame connected to the lower outer wall of one side of the gas chromatograph body by bolts, a filter plate fixedly arranged on the middle inner wall of the mounting frame and a plurality of baffles fixedly arranged on the top inner wall of the mounting frame, a plurality of drying components are arranged in the mounting frame, the drying components comprise a drying pipe whose upper portion passes through and is plugged into the top outer wall of the mounting frame, a wiper component is arranged in the mounting frame, the wiper component comprises a motor connected to the outer wall of one side of the mounting frame by bolts, a screw connected to the outer wall of one end of the motor output shaft by a coupling and a scraper slidably arranged in the mounting frame, a heat exchange mechanism is arranged on one side of the gas chromatograph body, the heat exchange mechanism comprises a water tank connected to the outer wall of one side of the gas chromatograph body by bolts, a circulating pump arranged in the water tank and a heat exchange pipe fixedly arranged on the outer wall of the water outlet end of the circulating pump, and two cooling fans are arranged on the outer wall of one side of the gas chromatograph body.

[0009] Preferably, a guide plate with an arc structure is fixedly provided on the lower inner wall of the installation frame, and air inlets distributed equally are opened on the outer wall of one side of the installation frame, and the bottoms of several baffles are respectively connected to the top outer wall of the filter plate by bolts, and a drain pipe is fixedly provided on the inner wall of one side of the installation frame.

[0010] Preferably, the outer wall of the drying tube is provided with equidistantly distributed ventilation holes, and the drying tube is filled with silica gel desiccant, a sealing plug is inserted into the upper inner wall of the drying tube, and a connecting block is fixedly provided on the outer wall at the top of the sealing plug.

[0011] Through the above scheme, the outside air is blocked by the baffle, and the moisture of the outside humid air adheres to the baffle under the action of inertia and is separated from the outside air, thereby performing the initial gas-liquid separation on the outside air, and then passes through the silica gel desiccant in multiple drying tubes again, so that relatively dry outside air enters the gas chromatograph.

[0012] Preferably, one end of the screw is connected to an inner wall of one side of the mounting frame through a bearing, and the scraper is screwed to an outer wall of the screw.

[0013] Through the above scheme, the motor output shaft drives the screw to rotate, and the screw drives the scraper to move along the inner wall of the installation frame, thereby transporting the water collected inside the installation frame to the water tank through the drain pipe.

[0014] Preferably, a top cover is connected to the top outer wall of the water tank by bolts, and the heat exchange tube passes through and is inserted into the bottom outer wall of the top cover. A connecting pipe is fixedly provided on the inner wall of one side of the water tank, and the connecting pipe is connected to the drain pipe through a connecting hose. A one-way valve is clamped on the outer wall at one end of the connecting pipe.

[0015] Preferably, the two heat dissipation fans are respectively connected to the outer wall of one side of the gas chromatograph body by bolts, and two air outlets are opened on the outer wall of one side of the gas chromatograph body close to the two heat dissipation fans.

[0016] Through the above scheme, two cooling fans are used to assist the internal fan of the gas chromatograph to transport hot air to the outside of the gas chromatograph body. During the flow of hot air, heat is exchanged with cold water in the heat exchange tube. Then the warm water in the heat exchange tube enters the water tank, and the air with lower temperature is transported to the outside of the gas chromatograph, increasing the temperature difference between the outside air and the hot air inside the gas chromatograph.

[0017] The beneficial effects of the utility model are:

[0018] 1. A gas-liquid separation mechanism and a drying component are provided. The baffle blocks the outside air. Under the action of inertia, the moisture of the outside humid air adheres to the baffle and is separated from the outside air, thereby performing the initial gas-liquid separation on the outside air. Subsequently, the outside air passes through the silica gel desiccant in multiple drying tubes again, so that the relatively dry outside air enters the gas chromatograph. The outside air can be dried to prevent the humid air from directly entering the gas chromatograph and causing the electrical components to be damp, thereby improving the practicality.

[0019] 2. A heat exchange mechanism and a cooling fan are provided. The two cooling fans assist the internal fan of the gas chromatograph to transport the hot air to the outside of the gas chromatograph body. During the flow of the hot air, it exchanges heat with the cold water in the heat exchange tube. Then the warm water in the heat exchange tube enters the water tank, and the air with a lower temperature is transported to the outside of the gas chromatograph, increasing the temperature difference between the outside air and the hot air inside the gas chromatograph. This can cool the hot air, prevent the hot air from gathering around the gas chromatograph, and improve the auxiliary heat dissipation effect.

[0020] In summary, the utility model can dry the outside air and prevent moist air from directly entering the gas chromatograph to cause electrical components to get damp, thereby improving practicality; it can cool the hot air and prevent the hot air from gathering around the gas chromatograph, thereby improving the auxiliary heat dissipation effect.
