DETAILED DESCRIPTION

[0026] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only as examples, and other obvious modifications can be conceived by those skilled in the art.

[0027] Referring to Figures 1-5 As shown in FIG. 1, a liquid chromatograph with a cooling structure includes a liquid chromatograph body 1, a water tank 3 fixed to a side wall of the liquid chromatograph body 1, and a water pump 4 installed on the inner wall of the bottom end of the water tank 3. A condenser pipe 2 is installed on the inner wall of one side of the liquid chromatograph body 1. The inlet and outlet ends of the condenser pipe 2 penetrate into the water tank 3, and the inlet end of the condenser pipe 2 is fixedly communicated with the output end of the water pump 4.

[0028] When the liquid chromatograph body 1 is cooled, the water pump 4 is turned on in advance. The water suction end of the water pump 4 continuously sucks the condensed water in the inner cavity of the water tank 3, so that the condensed water flows through the condenser pipe 2 and reflows into the condenser pipe 2. In this way, the condensed water can continuously cool the inner cavity of the liquid chromatograph body 1 during the flow process in the condenser pipe 2, preventing the temperature in the liquid chromatograph body 1 from being too high and causing damage to the electrical elements in the liquid chromatograph body 1.

[0029] In addition, the liquid chromatograph body 1 is a conventional instrument for liquid separation and analysis. Its internal structure, electrical element composition, and circuit principle are well known to the public, and will not be described in detail in this case.

[0030] Further, referring to Figure 3 As shown in FIG. 2, it is worth noting that a plurality of heat dissipation holes 5 are formed in the top of the water tank 3.

[0031] Through the arrangement of the heat dissipation holes 5, the hot air generated by the refluxing condensed water in the condenser pipe 2 can be effectively discharged, thereby achieving the effect of cooling the condensed water. This prevents the temperature of the condensed water from rising due to heat absorption during the continuous circulation process in the condenser pipe 2, thereby affecting the cooling effect of the liquid chromatograph body 1.

[0032] Although the above-mentioned embodiment can discharge the hot air in the water tank 3 through the dust removal net 8, it can achieve the effect of cooling the condensed water. However, the heat dissipation holes 5 still allow dust and impurities in the external air to enter the water tank 3, polluting the condensed water. Over a long period of time, the condensed water with dust and impurities flowing in the condenser pipe 2 is easy to cause blockage in the condenser pipe 2, thereby affecting the cooling effect of the condenser pipe 2 on the liquid chromatograph body 1.

[0033] Therefore, referring to Figure 1 and Figure 3 As shown in FIG. 3, it is worth noting that a multi-directional dust blocking part is arranged on the top of the water tank 3. A lifting part is arranged in the water tank 3 and cooperates with the multi-directional dust blocking part.

[0034] The multi-direction dust blocking part comprises a movable frame 7 in the shape of an inverted U slidingly arranged in the inner wall of the top end of the water tank 3, a ventilation window I is formed through the inner wall of the top of the movable frame 7, and a dust removal net I 8 is arranged in the ventilation window I, the dust removal net I 8 is attached to the top surface of the liquid chromatograph main body 1 and corresponds to the heat dissipation hole 5;

[0035] Through the arrangement of the dust removal net I 8, the dust and impurities in the air can be effectively prevented from directly entering the inner cavity of the water tank 3 to pollute the condensed water without affecting the effect of the hot gas being discharged outward through the heat dissipation hole 5, thereby ensuring the use effect of the condensed water.

[0036] However, the surface of the dust removal net I 8 is easily covered with a large amount of dust after long-term use, and if the dust layer on the dust removal net I 8 is not cleaned in time, the discharge rate of the hot gas outward will be reduced, causing the hot gas to accumulate in the water tank 3, thereby seriously reducing the heat dissipation of the condensed water.

[0037] Therefore, as shown in Figure 1 , Figure 3 and Figure 4 , it is worth noting that ventilation windows II are formed through the inner walls on both sides of the movable frame 7, and a dust removal net II 9 is arranged in the ventilation window II;

[0038] Through the arrangement of the lifting part and the dust removal net II 9, if the surface of the dust removal net I 8 is covered with a large amount of dust, causing the hot gas to accumulate in the inner cavity of the water tank 3, the lifting part can quickly act on the movable frame 7 to lift it up, thereby expanding the distance between the dust removal net I 8 and the water tank 3, reducing the blockage of the heat dissipation hole 5 by the dust removal net I 8, so that the hot gas can be normally discharged outward through the dust removal net II 9 on both sides, preventing the hot gas from accumulating in the inner cavity of the water tank 3.

[0039] Further, as shown in Figure 1 , it is worth noting that two shielding plates 6 are symmetrically fixed on the top surface of the water tank 3, and the movable frame 7 is slidingly attached between the two shielding plates 6;

[0040] Through the arrangement of the two symmetrically distributed shielding plates 6, when the movable frame 7 is pushed up by the lifting assembly to move the dust removal net I 8 upward, the two shielding plates 6 can shield the two open sides of the inverted U-shaped movable frame 7, respectively, thereby ensuring that the hot gas can only be discharged outward through the dust removal net II 9.

[0041] Further, as shown in Figure 3 and Figure 4 , it is worth noting that the lifting part comprises a bearing frame 10 which is detachably arranged at the bottom end of the movable frame 7, a driven gear plate I 12 which is vertically fixed to the bottom surface of the bearing frame 10, and a transmission rod 13 which is transversely arranged beside the driven gear plate I 12, and a transmission gear 14 which is tightly sleeved on the rod body of the transmission rod 13 and is in meshing engagement with the driven gear plate I 12;

[0042] The lifting part further comprises a driving motor 15 installed on the front side of the water tank 3 through a support, and an output shaft of the driving motor 15 penetrates into the water tank 3 and is fixedly connected with one end of the transmission rod 13;

[0043] A temperature alarm 17 is installed on the side wall of the water tank 3, a detection end of the temperature alarm 17 extends above the inner cavity of the water tank 3, and the temperature alarm 17 is electrically connected with the driving motor 15;

[0044] Through the temperature alarm 17 and the driving motor 15, the detection end can monitor the temperature of the inner cavity of the water tank 3 in real time. Once the temperature rises due to the heat accumulation in the water tank 3, the temperature alarm 17 sends an alarm to remind personnel, and the driving motor 15 is connected to the power supply, so that the output shaft of the driving motor 15 drives the transmission rod 13 to rotate, and the transmission gear 14 continuously engages with the driven gear plate one 12, thereby forming an upward pushing force on the bearing frame 10 and the movable frame 7 as a whole.

[0045] Further, referring to Figure 4 It is worth noting that the bearing frame 10 is fixed with an extension rod 11 between the bottom surface and the inner wall of the bottom end of the water tank 3.

[0046] Through the extension rod 11, the extension rod 11 can synchronously perform extension and contraction during the movement of the bearing frame 10, thereby effectively limiting the movement track of the bearing frame 10 and the movable frame 7 as a whole.

[0047] Further, referring to Figure 4 It is worth noting that the water tank 3 is further provided with an efficiency part for enhancing the refrigeration effect of the condensed water.

[0048] The efficiency part comprises a water cooling plate 18 slidably arranged on the inner wall of one side of the water tank 3 through a sliding block and groove, and a driven gear plate two 20 fixedly arranged at the bottom end of the water cooling plate 18, and the driven gear plate two 20 is engaged with the transmission gear 14.

[0049] The top surface of the water tank 3 is further fixedly provided with two connectors 19, and the two connectors 19 are respectively fixedly connected with the inlet and outlet ends of the water cooling plate 18 through spring hoses.

[0050] Through the efficiency part, the two connectors 19 are respectively connected with the cooling liquid inlet and outlet pipes, so that the cooling liquid is introduced into the inlet pipe, and the cooling liquid flows through the water cooling plate 18 and is discharged outwardly through the outlet pipe. The continuous flow of the cooling liquid in the inner cavity of the water cooling plate 18 can effectively cool the water cooling plate 18, and when the driving motor 15 is turned on to make the transmission gear 14 engage with the driven gear plate one 12 to lift the bearing frame 10 and the movable frame 7 as a whole, the transmission gear 14 can synchronously engage with the driven gear plate two 20 to make the water cooling plate 18 slide reversely and insert into the condensed water in the water tank 3, so as to quickly cool the condensed water and improve the heat dissipation of the condensed water.

[0051] Supplement, water-cooled plate 18 is liquid-cooled plate, is formed on the base plate using buried pipe, drilling, micro water channel processing, double layer welding and other ways to form flow channel, through liquid flow to take away heat, it is conventional refrigeration components of prior art, the internal structure of the case is not described.

[0052] Further, referring to Figure 3 And Figure 5 It is worth mentioning that the corners of the top surface of the movable frame 7 are penetrated by locking screws 16 fixed to the top surface of the bearing frame 10, and the ends of the locking screws 16 are threadedly connected with nuts abutting against the movable frame 7.

[0053] The knob nut makes the nut exit the locking screw 16 under the threaded structure, that is, the fixation of the movable frame 7 is released, so that the movable frame 7 can be simply pulled up, and the movable frame 7, the dust removal net one 8 and the dust removal net two 9 can be quickly removed as a whole, and then the dust and impurities on the dust removal net two 9 and the dust removal net one 8 can be conveniently cleaned.
