Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an intelligent heating reflux digestion instrument. Background Art

[0002] The automatic digestion reflux instrument is mainly composed of four parts. It uses microcomputer technology to perform timed control of the heating electric furnace plate and fan, and can heat six conical flask reflux devices at the same time. A glass burr reflux tube is used instead of a spherical reflux tube, and air cooling technology is used instead of tap water cooling. The cooling part is mainly completed by a burr condenser and a fan. The upper part of the condenser is spherical, and the catalyst is added here to prevent the instantaneous volatilization of light components in the sample. The lower part is "burr" shaped. The three opposing "burrs" extending from the condenser wall on a plane increase the cooling area compared to a simple spherical condenser, and can block the passage of volatile substances and vapors. In addition, the dual functions of cooling water in the upper spherical reflux tube and the fan inside the machine ensure the reflux cooling of the sample, which also plays an important role in water quality testing.

[0003] A Chinese utility model patent with authorization publication number CN209027896U discloses an intelligent heating digestion and reflux instrument, comprising a control body, a bracket symmetrically arranged around the lower surface of the control body, a base at the bottom of the bracket, a heating plate on the upper surface of the base, a light wave tube within the heating plate, fans symmetrically arranged on both inner walls of the control body, a power switch on one outer wall of the control body, a clamping frame symmetrically arranged on the upper surface of the control body, a water cooling chamber within the clamping frame, a condenser connected to the bottom of the water cooling chamber, and the condenser pipe passing through the elastic mesh at the horizontal end of the clamping frame and the interior of the control body, and extending to the inner cavity of the digestion bottle on the surface of the heating plate. The digestion and reflux instrument of this utility model has a simple and reasonable overall structural design, achieving the convection cooling effect of the condenser pipe while achieving high heating efficiency and avoiding burns, thus having strong practicality.

[0004] Although the prior art solution mentioned above uses two symmetrical fans to generate convective cooling air, this can result in uneven cooling of the condenser tube. The contact angle and distance between the cooling airflow and the condenser tube may vary, resulting in good cooling in some areas and insufficient cooling in others. Therefore, a smart heating reflux digester is urgently needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent heating reflux digestion instrument to address the problem in the prior art described above, where, despite the provision of two symmetrical fans to generate convective cooling air, the cooling of the condenser tube may be uneven. Different locations on the condenser tube may have different contact angles and distances with the cooling airflow, resulting in better cooling in some areas and insufficient cooling in others.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent heating reflux digestion instrument, comprising: a body, a control panel provided on the outer surface of the body, a clamping frame fixedly connected to the outer surface of the body, a digestion bottle movably connected to the internal part of the clamping frame, a fixing plate fixedly connected to the side surface of the body, a support frame fixedly connected to the outer surface of the fixing plate, a water-cooling assembly movably connected to the internal part of the fixing plate, a fan unit movably connected to the side surface of the water-cooling assembly, a fixing bolt movably connected to the outer surface of the fan unit, a condensing pipe fixedly connected to the internal part of the water-cooling assembly, a condenser fixedly connected to the upper surface of the water-cooling assembly, a sliding groove provided on the side surface of the fixing plate, and an air hole provided on the side of the fixing plate away from the sliding groove.

[0007] Preferably, a guide groove is provided at the inner bottom end of the fixing plate, and a rotating wheel is movably connected to the upper surface of the guide groove.

[0008] Preferably, a fixing ring is fixedly connected to the bottom of the water cooling assembly, and a connecting rod is movably connected inside the fixing ring.

[0009] Preferably, the outer surface of the connecting rod is fixedly connected to a rotating wheel, and the outer surface of the connecting rod is movably connected to a ring.

[0010] Preferably, a support rod is fixedly connected to the outer surface of the collar, and one end of the support rod away from the collar is fixedly connected to the bottom of the water cooling assembly.

[0011] Preferably, the sliding groove is provided on the side surface of the fixing plate, and the fan unit is slidably connected inside the sliding groove.

[0012] Preferably, the condenser is fixedly connected above the water-cooling assembly, the condensing pipe is fixedly connected inside the water-cooling assembly, and the water-cooling assembly is fixedly connected together in three groups.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up a water-cooling component and a condenser, the water-cooling component is installed on the outside of the side of the body. Under the action of the water-cooling component, the condenser can be cooled more evenly through the uniform flow of circulating water, making the temperature of the entire condenser more uniform. At the same time, the water-cooling device can utilize the high specific heat capacity of water to more effectively absorb and take away heat, quickly reduce the temperature of the condenser and related components, ensure that the experiment is carried out under appropriate temperature conditions, and improve the overall cooling efficiency.

[0015] By providing the connecting rod and the rotating wheel, the friction force can be reduced when the water cooling component is installed, so that the water cooling component can be installed more conveniently and quickly inside the fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Specifically, through the setting of the control panel 2, the internal temperature of the body 1 can be effectively displayed in real time, and the control panel 2 is connected to the air cooling system inside the body 1. When the control panel 2 detects that the local temperature is too high, the control unit can automatically adjust the fan speed or the flow rate of the water cooling system to ensure that the condenser 11 can operate within the appropriate temperature range, further optimizing the uniformity of cooling.

[0024] See also Figure 1-4 The inner bottom end of the fixing plate 5 is provided with a guide groove 19. The guide groove 19

[0025] The upper surface of the frame is movably connected with a rotating wheel 16.

[0026] Specifically, by providing the guide groove 19 , the guide groove 19 can effectively play a guiding role during the sliding process of the rotating wheel 16 , thereby ensuring the smoothness of the device.

[0027] See also Figure 1-4 A fixing ring 14 is fixedly connected to the bottom of the water cooling assembly 7 , and a connecting rod 15 is movably connected inside the fixing ring 14 .

[0028] Specifically, by providing the fixing ring 14 , when the connecting rod 15 rotates, the fixing ring 14 can support the connecting rod 15 , thereby preventing the connecting rod 15 from being disjointed when driving the rotating wheel 16 .

[0029] See also Figure 1-4 The outer surface of the connecting rod 15 is fixedly connected to a rotating wheel 16 , and the outer surface of the connecting rod 15 is movably connected to a ring 17 .

[0030] Specifically, by setting the rotating wheel 16, when the water cooling component 7 is pushed into the interior of the fixed plate 5, the friction between the water cooling component 7 and the fixed plate 5 can be reduced, so that the water cooling component 7 can be smoother during operation, and the inner side material of the fixed plate 5 is magnetic, and when the water cooling component 7 is slid into the interior of the fixed plate 5, the water cooling component 7 can be adsorbed on the inside of the fixed plate 5.

[0031] See also Figure 1-4 The outer surface of the collar 17 is fixedly connected to a support rod 18 , and one end of the support rod 18 away from the collar 17 is fixedly connected to the bottom of the water cooling assembly 7 .

[0032] Specifically, the support rod 18 can be provided to pull the connecting rod 15, thereby effectively preventing the connecting rod 15 from being deformed or falling off during long-term use.

[0033] See also Figure 1-4 The sliding groove 9 is opened on the side surface of the fixed plate 5, and the fan unit 8 is slidably connected to the inside of the sliding groove 9.

[0035] See also Figure 1-4 The condenser 13 is fixedly connected to the top of the water-cooling assembly 7, the condenser pipe 11 is fixedly connected to the inside of the water-cooling assembly 7, and the water-cooling assembly 7 is fixedly connected together in three groups.

[0036] Specifically, by setting up the water cooling assembly 7, the modularization of the water cooling device can be achieved. When one of the groups is damaged or under repair, it can be replaced in time, thereby avoiding delaying work efficiency.

[0037] Working principle: When in use, the digestion bottle 4 is placed into the interior of the body 1 along the clamping frame 3, and the fixing plate 5 is fixedly connected to the side surface of the body 1 through the support frame 6, and then the water-cooling component 7 is moved along the side of the fixing plate 5 so that the fan group 8 can slide along the sliding groove 9 into the interior of the water-cooling component 7. During the sliding process of the water-cooling component 7, the rotating wheel 16 at the bottom of the water-cooling component 7 will contact the inner bottom end of the fixing plate 5, thereby reducing the friction between the fixing plate 5 and the water-cooling component 7, making the water-cooling component 7 smoother during operation, and then align the side of the water-cooling component 7 away from the fan group 8 at the air hole 12. When the control panel 2 detects that the internal temperature is too high, the sliding groove 9 can be effectively started, thereby realizing a dual cooling mechanism. At the same time, the water cooling system can play a key role in conditions where the temperature is high or the cooling speed is extremely high, thereby improving the cooling efficiency and helping to maintain the stability of the cooling effect.
