Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection equipment, in particular to a COD digester with a cooling function. Background Art

[0002] A COD digester is an instrument specifically designed to measure the chemical oxygen demand (COD) in water samples. COD is a key indicator of the degree of organic contamination in water. By measuring the COD value, we can understand the organic content in the water and assess the water's contamination status. The main function of a COD digester is to oxidize and decompose the organic matter in the water sample, converting it into a measurable form for subsequent COD determination.

[0003] The existing authorization announcement number is CN218481303U, which relates to a COD digester with a cooling function, belonging to the technical field of environmental testing equipment. It includes a rack and a digestion bottle. One end of the rack is connected to a placement box, and the other end of the rack is connected to an air cooling box. The placement box is provided with a number of placement countersunk holes for placing the digestion bottles. The end walls on both sides of the placement box are connected to cooling fans for cooling the digestion bottles. The placement box is provided with a mounting assembly for mounting the cooling fan. This application has the effect of improving the experimental efficiency of COD reflux digestion experiments performed using a COD digester.

[0004] With the above technical solution, although the digestion bottle is cooled by a cooling fan and the cooling fan is protected by a protective cover when not in operation, the cooling fan has no external protective function when cooling the digestion bottle. Therefore, workers may accidentally touch the cooling fan during operation, causing safety accidents. In addition, it is inconvenient to adjust the position of the cooling fan and disassemble and repair it. Therefore, we provide a COD digester with a cooling function. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figures 1-4As shown, in this embodiment, a COD digester with a cooling function includes: a cooling mechanism 1, the cooling mechanism 1 includes a placement box 11, a heat dissipation groove 12 is opened on one side of the placement box 11, fixed plates 13 are provided on both sides of the placement box 11, screws 14 are provided in the threaded grooves opened at the bottom of the two fixed plates 13, and knobs 15 are provided at the bottom ends of the two screws 14. The placement box 11 is fixedly connected to the fixed plates 13 on both sides, the outer side of the screw 14 is threadedly connected to the inner wall of the threaded groove opened at the bottom of the fixed plate 13, and the bottom end of the screw 14 is fixedly connected to the selection knob 15. A movable plate 16 is provided inside the two fixed plates 13, and a protective shell 18 is provided on the top of the two movable plates 16. Slide grooves 17 are opened on both sides of the inner walls of the two fixed plates 13, and sliders 19 are provided on both sides of the two protective shells 18. The top of the screw 14 is rotatably connected to the bottom of the movable plate 16, the top of the movable plate 16 is fixedly connected to the bottom of the protective shell 18, and the two sides of the protective shell 18 are fixedly connected to the sliders 1 9. A dust screen 110 is provided on the opposite side of the two fixed plates 13. The outer side of the slider 19 is slidably connected to the inner wall of the slide groove 17. The outer side of the protective shell 18 is docked in the slot opened at the top of the fixed plate 13. The inner wall of the protective shell 18 is fixedly connected to the dust screen 110 on the side close to the digestion bottle 34. Three mounting shells 111 are provided inside the two protective shells 18. A cooling fan 112 is provided in each of the six mounting shells 111. The outer side of the mounting shell 111 is fixedly installed with the inner wall of the protective shell 18. A cooling fan 112 is fixedly installed inside the shell 111, and a support frame 31 is fixedly connected to one side of the top of the placement box 11. Digestion bottles 34 are docked in multiple slots opened on the top of the placement box 11. Multiple cooling bottles 32 are fixedly installed on the top of the above-mentioned support frame 31. The bottom of the cooling bottle 32 is docked with the top of the return pipe 33, and the bottom end of the return pipe 33 passes through the slot opened on the top of the support frame 31 and is docked at the top of the digestion bottle 34. A disassembly mechanism 2 is provided on the opposite side of the two fixed plates 13.

[0025] In this embodiment, when the COD digester performs a COD reflux digestion experiment, since the surface temperature of the digestion bottle 34 is high after being heated, in order to avoid burns to the operator, it is necessary to use the cooling mechanism 1 to cool the digestion bottle 34. Therefore, the staff can rotate the screw 14 counterclockwise. When the screw 14 rotates counterclockwise, the movable plate 16 and the protective shell 18 will be pushed upward, and the sliders 19 provided on both sides of the protective shell 18 will slide upward in the chute 17 during the upward movement of the protective shell 18. The sliders 19 and the chute 17 can make the protective shell 18 move up more smoothly, reducing the gap between the outside of the protective shell 18 and the fixed plate 13. Due to the friction of the inner wall of the card slot, when the screw is rotated to the limit, the protective shell 18 will be almost exposed on the top side of the fixed plate 13, thereby ensuring that the heat dissipation fan 112 can cool the digestion bottle 34 when working. By starting the heat dissipation fan 112 inside the protective shell 18, the digestion bottle 34 is cooled and the heat is dissipated, so that the substance in the digestion bottle 34 reaches the required temperature more quickly, thereby shortening the experimental time and improving the efficiency of the experiment. In addition, the protective shell 18 can not only protect the heat dissipation fan 112, but also prevent the staff from accidentally touching the heat dissipation fan 112 in the working state.

[0026] like Figure 2-Figure 4 As shown, the disassembly mechanism 2 includes a breathable plate 21, and the top and bottom of the breathable plate 21 close to the protective shell 18 are fixedly connected to multiple locking balls 22. The top and bottom of the protective shell 18 away from the dustproof net 110 are provided with multiple fixing grooves 23, and the outside of the locking balls 22 are clamped in the fixing grooves 23.

[0027] In this embodiment, the air permeable plate 21 is provided to ensure that the airflow generated by the cooling fan 112 can flow smoothly, while avoiding damage to the cooling fan 112 caused by external factors. The staff can slightly pull the air permeable plate 21 to make the ball 22 disengage from the fixing groove 23, thereby facilitating the staff to clean and repair the cooling fan 112 in the protective shell 18.

[0028] The utility model provides a COD digester with a cooling function. The specific working principle is as follows:

[0029] When the COD digester performs a COD reflux digestion experiment, since the surface temperature of the digestion bottle 34 is high after being heated, in order to avoid burns to the operator, the staff can rotate the screw 14 counterclockwise. When the screw 14 rotates counterclockwise, it will generate an upward lifting force on the movable plate 16 and the protective shell 18. As the protective shell 18 moves upward, the sliders 19 on both sides thereof will also slide upward in the chute 17. When the screw 14 is rotated to the limit, the protective shell 18 will be almost completely exposed on the top side of the fixed plate 13, so that Ensure that the heat dissipation fan 112 can cool the digestion bottle 34 when working. By starting the heat dissipation fan 112 provided inside the protective shell 18, the digestion bottle 34 can be effectively cooled and dissipated, so that the substance in the digestion bottle 34 can reach the required temperature faster. In order to facilitate the staff to clean and maintain the heat dissipation fan 112 in the protective shell 18, the air permeable plate 21 can also be slightly pulled to disengage the card ball 22 from the fixing groove 23, thereby facilitating the staff to clean and maintain the heat dissipation fan 112 in the protective shell 18.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
