Problems solved by technology

[0003] 1. On-line analysis instruments (COD, ammonia nitrogen, TOC, etc.) need to be equipped with water sample pretreatment devices. Most of the pretreatment devices currently on the market only have filtering functions, but not water sample homogenization functions, which cannot guarantee that the on-line analysis instruments ( COD, ammonia nitrogen, TOC, etc.) No large particles of impurities enter into the water samples, resulting in large data spikes, which damage the interests of sewage enterprises, and are installed and used separately from online analysis instruments (COD, ammonia nitrogen, TOC, etc.), occupying limited monitoring The space of the station room increases the cost input
[0004] 2. Most of the reagents consumed by online analysis in

Example Embodiment

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0024] Such as Figure 1-4 As shown, a new type of over-standard sample retention instrument in this embodiment includes an instrument body 1, which includes a skeleton 11 and a shell. The shell includes a front door panel 12, a rear back panel 13 and two side door panels 14. The front door panel 12 is provided with There is a door lock 15 and the front door panel 12 is connected to the frame 11 by a hinge. The i...

Abstract

The present invention discloses a novel overstandard sample retention instrument, which comprises an instrument body, wherein a water sample circulation pipeline is arranged on the right-rear side inside the instrument body and is connected to a water sample pre-treatment device, the water sample pre-treatment device is arranged on one side inside the instrument body, comprises a buffer cup, a filter, a homogenizing stirrer, a washing valve and a water discharge valve, and is connected to an overstandard sample retention device, the overstandard sample retention device comprises a peristaltic pump, a sampling bottle, a distribution arm and a water discharge funnel, the peristaltic pump is arranged on a peristaltic pump bracket positioned above the right side inside the instrument body, the sampling bottle, the distribution arm and the water discharge funnel are arranged inside a refrigeration box, the sampling bottle is arranged on a sampling bottle installation seat, the distribution arm is arranged above the sampling bottle, and the upper end of the instrument body is provided with a power supple and a control circuit board. The novel overstandard sample retention instrument of the present invention has characteristics of high integration degree, body miniaturization, and low cost.

Description

technical field [0001] The invention relates to an instrument for retaining samples exceeding the standard, in particular to a novel instrument for retaining samples exceeding the standard with three functions of water sample pretreatment, retaining samples exceeding the standard and refrigerating reagents. Background technique [0002] At present, the solution for online detection of pollution sources is generally online analysis instruments (COD, ammonia nitrogen, TOC, etc.) However, the existing technology and equipment will find the following two shortcomings in engineering practice: [0003] 1. On-line analysis instruments (COD, ammonia nitrogen, TOC, etc.) need to be equipped with water sample pretreatment devices. Most of the pretreatment devices currently on the market only have filtering functions, but not water sample homogenization functions, which cannot guarantee that the on-line analysis instruments ( COD, ammonia nitrogen, TOC, etc.) No large particles of imp...
