Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a COD pre-installed reagent tube box for wastewater detection. Background Art

[0002] COD (Chemical Oxygen Demand) prefabricated reagents are mainly used to detect the COD (Chemical Oxygen Demand) values ​​in surface water, groundwater, drinking water, boiler water, aquaculture water, wastewater, municipal sewage, etc. COD prefabricated reagents are usually contained in COD pre-installed reagent tubes, which are positioned and placed in the test kit box for easy transportation and use.

[0003] The existing test kit for placing COD pre-installed reagent tubes adopts a foam board of foam material for positioning and placement. The COD pre-installed reagent tubes are extremely inconvenient to use and can only be taken out one by one for use. In the actual COD detection process of wastewater, due to the need for simultaneous batch detection, the COD pre-installed reagent tubes for testing need to have a fixed bracket similar to a test tube rack as a temporary fixed placement, and the existing test kit is not convenient for placing the COD pre-installed reagent tubes during the test. Therefore, it is necessary to provide additional auxiliary equipment such as test tube racks during the detection process to achieve temporary fixed placement of the reagent tubes. Therefore, it is particularly inconvenient for occasions where sewage needs to be measured on site. For this reason, it is necessary to design a reagent tube box that is convenient for positioning and placing COD pre-installed reagent tubes, convenient for the transportation and placement of COD pre-installed reagent tubes, and can also achieve a test kit similar to a test tube rack to ensure that the reagent tubes can be temporarily placed during the measurement process on site.

The utility model has a plug-in foam which is plugged in between two placement units so that the two placement units can be well fixed inside the box body. When on-site sewage detection is required, the box cover can be opened to take out the plug-in foam and then take out the placement unit. The COD pre-installed reagent tube positioned in the placement unit can be conveniently taken out for use by using the placement unit. At the same time, the placement rack arranged in an L shape can be used as a positioning rack in the test process during the determination of the COD pre-installed reagent tube, which greatly facilitates the use of the test kit in on-site detection. Moreover, the fixed foam is fixed by magnetic adsorption, so that the fixed foam can be conveniently removed from the placement rack.

[0006] Furthermore, an upper foam plate is provided on the upper part of the two placement units. The upper foam plate provides a buffer between the two placement units and the box cover, realizes upper protection of the COD pre-installed reagent tube, further fixes the two placement units in the box body, and thus improves the safety of the COD pre-installed reagent tube during transportation.

[0007] Furthermore, the first magnetic strip is flush with the back panel surface, and the second magnetic strip is flush with the side wall surface of the fixed foam. The first magnetic strip is built into the back panel, and the second magnetic strip is built into the fixed foam, so that the fixed foam surface can be better attached to the back panel surface by magnetic adsorption.

[0008] Furthermore, two first magnetic strips are arranged on the back plate, and the two first magnetic strips are evenly arranged on the back plate, and correspondingly, two second magnetic strips are arranged on the fixed foam. By setting the magnetic force adsorption between the two first magnetic strips and the two second magnetic strips, the magnetic adhesion of the fixed foam is firm and even.

[0009] Furthermore, the upper foam plate has a plug-in groove at its bottom, and the plug-in foam has its upper part sleeved in the plug-in groove. The plug-in groove can enhance the positioning effect between the upper foam plate and the plug-in foam.

[0010] Furthermore, the upper foam plate has a second fixing groove corresponding to the first fixing groove at its bottom. The second fixing groove can position the COD pre-installed reagent tubes one by one from the top, thereby preventing multiple COD pre-installed reagent tubes plugged into the first fixing groove from colliding with each other due to shaking.

[0011] Furthermore, the upper foam board has two pairs of hand holes on its upper part. By providing the hand holes, when taking out the upper foam board, fingers can be inserted into the hand holes to take out the upper foam board.

[0012] The utility model adopts a placement unit to position the COD pre-installed reagent tube inside the box body, and the COD pre-installed reagent tube can be easily taken out by taking out the placement unit. The placement rack and fixed foam of the placement unit are used to solve the placement problem of the COD pre-installed reagent tube during sewage testing.

[0013] The utility model can well realize the positioning and placement of two placement units inside the box body by plugging in the foam of the placement unit, and at the same time utilizes the upper foam plate to position the plugged in foam at the upper part, so that the upper foam protects the upper part of the COD pre-installed reagent tube placed in the placement unit, thereby improving the safety of the COD pre-installed reagent tube during transportation.

[0024] Reference Figure 4 Each placement unit 3 includes a placement frame 31 and a fixed foam 32, wherein, with reference to Figure 5 , the placement rack 31 is set in an L shape, wherein the long side of the L shape is the back plate 311, and one or more horizontally arranged first magnetic strips 314 are arranged on the inner side of the back plate 311. In a more preferred manner, the back plate 311 is provided with two first magnetic strips 314, and the two first magnetic strips 314 are evenly arranged on the back plate 311. In order to better achieve magnetic plane adsorption, the first magnetic strip 314 is built into the back plate 311 so that the first magnetic strip 314 is flush with the surface of the back plate 311. wherein, the short side of the L shape is the bottom plate 313, and the two sides of the L shape have two side plates 312, and a positioning space for positioning the fixed foam 32 is formed between the two side plates 312, the back plate 311 and the bottom plate 313 of the placement rack 31. Since the positioning space is a semi-enclosed structure, the fixed foam 32 is convenient for moving, adsorbing and fixing. Moreover, the COD pre-installed reagent tube 4 fixed in the fixed foam 32 has more operating space, which facilitates the removal of the COD pre-installed reagent tube 4.
