Description
Technical field
The utility model relates to a kind of testing jig, is specifically related to COD content detection sample testing frame in the sewage of a kind of workshop.
Background technology
Enterprise is in order to protect water surrounding; the monitoring to sewage discharge must be strengthened; water quality detection mainly refers to measure the project of the mensuration such as BOD in water, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, dissolved oxygen; wherein the detection of COD is the most important thing, is most important for Chinese environmental protection industry.
Polyether product all produces a large amount of sewage and recirculated water in the aftertreatment in initial polymerization, later stage and the preparation process of final finished product; especially POP produces a large amount of sewage needs us carrying out promptly and accurately to detect; general facilities workshop adjusts according to these data; the water quality of outer row is up to state standards, protects water resources. Particularly at POP, because viscosity is relatively big, turnout is big, is again without intermittent type production technique, makees sample frequent, it is necessary to supplements a large amount of water, and produces a large amount of externally discharged waste waters. This just needs us can provide the analytical data of COD fast and accurately.
COD constent temperature heater is the well heater that classical way analyzes COD in sewage, and instrument adopts digitizing setting, and display Heating temperature, controls Heating temperature automatically. Heat-up rate is fast, and homo(io)thermism is even, simple to operate, stable and reliable for performance. There is power saving, without water coolant, take up space little, the advantage such as easy to operate. Because of COD need 166 ± 2 DEG C degree reflux after 2 hours under room temperature or frozen water cooling. And COD sample cup temperature height is not easy to fix, the container putting into cooling is often toppled over, and sample is destroyed. Usually once need cooling and titration 7,8 samples, the requirement causing multiple sample all to concentrate in together, defining a firmly temperature field, be unfavorable for cooling fast, do not reach in time, provide data for producing accurately.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide COD content detection sample testing frame in the sewage of a kind of workshop, it is to increase effect when cooling multiple sample, facilitates the titration of analysis personnel, to avoid chaotic and collides the problem toppled over.
COD content detection sample testing frame in the sewage of workshop described in the utility model, comprise the casing of opening upwards, the opening place of casing arranges orthogonal detached strips, the opening of casing is divided into multiple room by orthogonal detached strips, each room arranges fixed frame, being provided with hole in the middle of fixed frame, the bottom of box house arranges collet.
Casing can be rectangular parallelepiped or square, has opening upwards. The opening place of casing arranges orthogonal detached strips, and the opening of casing is divided into multiple room by orthogonal detached strips, it is preferable that be divided into 4-9 room, and detached strips is parallel with the wall of casing or vertical, and in terms of opening, each room is preferably square. Each room arranges fixed frame, it is provided with hole in the middle of fixed frame, when sample is carried out COD test, sample cup is positioned in hole, fixing for each sample, slightly larger than the diameter of sample cup, is solved problem sample cup being toppled over because buoyancy during cooling is big simultaneously, and each sample cup is no longer in close contact by the diameter in hole, respective refrigeration cycle space is defined, it is to increase effect during the multiple sample of cooling around sample cup. During titration, multiple sample cup can be put by sequence number safety is fixing, facilitates the titration of analysis personnel, to avoid chaotic and collide the problem toppled over.
In the bottom of box house, each hole corresponding arranges collet. Collet can be circular or square, is placed in hole by sample cup during test, and the bottom of sample cup is placed on collet, makes sample cup more stable.
Filling it up with heat-eliminating medium in casing, collet has a segment distance bottom casing, defines the constant temperature cooling field of a circulation like this, the time required for shortening cooling, it is to increase cooling performance around sample cup.
As the preferred technical scheme of one, in the middle of below casing, position is provided with support, and frame upper is provided with lift cylinder, and lift cylinder top is provided with rotating machine, and rotating machine top is provided with turning axle, and turning axle top is connected with bottom casing. During use, lift cylinder can regulate the height of casing, and rotating machine and turning axle can realize the rotation of casing, when there being multiple sample, tests convenient.
In sum, the utility model has the following advantages:
The utility model is practical and convenient, when solving COD content detection in the sewage of workshop because when cooling, buoyancy is big problem that sample cup is toppled over, and each sample cup is no longer in close contact, around sample cup, defines respective refrigeration cycle space, it is to increase effect during the multiple sample of cooling. During titration, multiple sample cup can be put by sequence number safety is fixing, is convenient to shifting liquid and the titration of analysis personnel, to avoid chaotic and collide the problem toppled over.
