Technical Field

[0001] This utility model relates to the field of water environment monitoring technology, and in particular to a COD analysis and digestion device for water environment monitoring. Background Technology

[0002] A chemical oxygen demand (COD) digester is a specialized COD analysis digestion device for water environment monitoring. Its main function is to determine the COD content in water samples through a digestion reaction. When using this COD analysis digestion device for water environment monitoring, the digestion bottle containing the added reagents is typically placed on the black crystal panel of the device. This panel heats the medium inside the digestion bottle, and the condenser collects the heat, facilitating the analysis of the water environment.

[0003] However, the black crystal panel of common COD analysis digestion devices for water environment monitoring is usually exposed, which poses a risk of burns when placing and removing reaction flasks. Furthermore, as the number of flasks increases, it becomes difficult to align them with the condenser port at the top of the device, and there is also a risk of bumping into other reaction flasks. We propose a COD analysis digestion device for water environment monitoring. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a COD analysis and digestion device for water environment monitoring.

[0005] The technical solution of this utility model is as follows: A COD analysis and digestion device for water environment monitoring includes a frame and a digestion bottle. A heating component is installed on the placement platform of the frame to facilitate the lifting and lowering of the digestion bottle. The heating component includes a cylinder, and the output end of the cylinder is connected to a heat insulation plate. A black crystal panel is installed on the top wall of the heat insulation plate. A protective cover is provided on the placement platform of the frame to provide protection. A positioning component is installed on the top inner wall of the protective cover to facilitate the positioning of the digestion bottle. The positioning component includes positioning clamps. Rubber pads are installed on the side walls of the four positioning clamps. Second I-beam hinges and first I-beam hinges are symmetrically arranged on the four positioning clamps. Torsion springs are sleeved inside the two first I-beam hinges.

[0006] Preferably, a controller is installed on the front wall of the rack, and a condenser bottle is installed on the top wall of the rack, with the inlet end of the digestion bottle corresponding to the inlet position of the condenser bottle.

[0007] Preferably, a positioning port is provided on the bottom wall of the cylinder, and the cylinder is installed in the positioning port.

[0008] Preferably, the heat insulation plate and the black crystal panel are mounted on the placement platform of the frame, and the bottom wall of the heat insulation plate is connected to the output end of the cylinder.

[0009] Preferably, the protective cover has a placement opening, and the plurality of positioning components are respectively installed at the placement opening corresponding to the position.

[0010] Preferably, each of the four positioning clamps is symmetrically provided with a first rotating hole and a second rotating hole, and the two first I-beam hinges are respectively disposed in the first rotating hole corresponding to their positions, and the two second I-beam hinges are respectively disposed in the second rotating hole corresponding to their positions.

[0011] Preferably, the four positioning clamps are divided into two groups, and two torsion springs are respectively disposed at the positioning clamps in each group, with the two ends of the two torsion springs respectively connected to the positioning clamps corresponding to the positions.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention inserts the digestion bottle into the corresponding positioning component, allowing multiple positioning clamps to rotate with the assistance of the second and first I-beam hinges. Rubber pads clamp and position the digestion bottle, preventing it from tipping over during handling. The adjustable rotation of the multiple positioning clamps allows for clamping and positioning digestion bottles of different diameters, improving practicality. The rubber pads prevent damage to the outer wall of the bottle during positioning. A protective cover further protects against accidental burns from the black crystal panel during handling. Simultaneously, the cylinder's push, in conjunction with the heat insulation plate, automatically inserts the digestion bottle into the inlet of the condenser bottle, achieving automatic sealing and reducing the risk of leakage.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0019] like Figures 1 to 3 As shown, the present invention proposes a COD analysis and digestion device for water environment monitoring, comprising a frame 1 and digestion bottles 4. A controller 2 is fixedly installed on the wall of the frame 1 facing forward for easy operation by staff. An opening is provided on the top wall of the frame 1, and multiple condensation bottles 3 are respectively installed at the corresponding openings and fixedly installed on the top wall of the frame 1. Multiple digestion bottles 4 are placed on the frame 1 and located below the multiple condensation bottles 3. The inlet end of the multiple digestion bottles 4 corresponds to the position of the multiple openings, which is convenient for inserting the inlet end of the digestion bottle 4 into the opening to cooperate with the condensation bottles 3. A protective cover 6 is installed on the top wall of the frame 1 platform, and the multiple digestion bottles 4 are respectively placed in the multiple placement openings opened on the top wall of the protective cover 6.

[0020] Furthermore, a heating assembly 5 is installed on the placement platform of the frame 1 to facilitate the lifting and lowering of the digestion bottle 4. The heating assembly 5 includes a cylinder 51, a heat insulation plate 52, and a black crystal panel 53. The cylinder 51 is located in a positioning port opened on the bottom wall of the frame 1, and part of the outer wall of the cylinder 51 is fixedly connected to the inner wall of the positioning port. The heat insulation plate 52 and the black crystal panel 53 are both placed on the placement platform of the frame 1. The black crystal panel 53 is fixedly installed on the top wall of the heat insulation plate 52, and the bottom wall of the heat insulation plate 52 is connected to the output end of the cylinder 51. The digestion bottle 4 is placed on the black crystal panel 53. This design facilitates heating of the digestion bottle 4 under the action of the black crystal panel 53. Simultaneously, the black crystal panel 53 is also located inside the protective cover 6, which helps prevent accidental burns from contact with the black crystal panel 53 during the placement and handling of the digestion bottle 4, thus improving safety. Furthermore, driven by the cylinder 51, the heat insulation plate 52, in conjunction with the black crystal panel 53, can lift the digestion bottle 4 placed on its top wall, allowing the inlet end of the digestion bottle 4 to automatically insert into the corresponding opening, achieving automatic sealing and reducing the risk of leakage during use.

[0021] Furthermore, a positioning component 7 is installed on the top inner wall of the protective cover 6 to facilitate the positioning of the digestion bottle 4. The positioning component 7 includes positioning clamps 71, rubber pads 72, first I-beam hinges 73, second I-beam hinges 74, and torsion springs 75. The four positioning clamps 71 are evenly divided into two groups, with the two positioning clamps 71 in each group arranged one above the other. Each of the four positioning clamps 71 has a first rotating hole and a second rotating hole symmetrically opened. The two first I-beam hinges 73 are respectively set in the first and second holes at their corresponding positions. The two torsion springs 75 are sleeved on the two first I-beam hinges 73 and are located between the two positioning clamps 71 in each group. The ends of the two torsion springs 75 are fixedly connected to the opposite wall of the two positioning clamps 71 in each group, which is beneficial for the two positioning clamps in each group to be driven by the torsion springs 75 after the two positioning clamps 71 in each group have rotated. The rod 71 is reset, and two second I-beam hinges 74 are set in two second rotating holes and are symmetrically arranged, so that the two sets of positioning clamping rods 71 ​​can rotate with the assistance of the first I-beam hinge 73 and the second I-beam hinge 74, thereby completing the purpose of clamping and positioning the digestion bottle 4 placed therein. This helps to maintain the stability of the digestion bottle 4 during use and reduces the risk of it tipping over when it is picked up or placed down. Due to the setting of multiple sets of positioning components 7, it is easier to reduce the risk of tipping over when it is bumped into other digestion bottles 4. Furthermore, with the movable adjustment of the positioning clamping rods 71, it is convenient to use digestion bottles 4 of different diameters, improving practicality. Four rubber pads 72 are respectively installed on the side wall of the positioning clamping rods 71 ​​and are located at the clamping surface of the positioning clamping rods 71. This facilitates contact with the outer surface wall of the digestion bottle 4 during the clamping and positioning process, reducing the risk of clamping the outer surface of the digestion bottle 4 during the positioning process.

[0022] The above specific embodiments are merely several preferred embodiments of this utility model.
