The sampler comprises a circulating pipe, a circulating pump and a sampler body, wherein the circulating pipe is connected to a diallyl phthalate synthesis kettle, the circulating pump is arranged on the circulating pipe, and the sampler body is arranged on the circulating pipe; the sampler body comprises a sampling container; and a sampling hole is formed on the sampling container. The sampler disclosed by the utility model ensures the sampling randomness, prevents material leakage, improves the working environment of the operators, is convenient to mount and overhaul, and has high safety in operation.
Description
Technical field
The utility model relates to a kind of chemical plant, is specifically related to a kind of ST that in the diallyl phthalate production run, is used for inspection by sampling.
Background technology
Diallyl phthalate can prepare the DAP plastics, and these plastics are the excellent thermosetting plasticses of a kind of electric property, and its characteristics: electrical property is excellent, and under the condition of high temperature, changes less; During moulding mobile better, be prone to make complex-shaped small-sized and have a making of tiny inserts; Dimensional stability is good; To the metal insert non-corrosiveness.Therefore the DAP plastics are to make electrical equipment and the indispensable a kind of material of electronic component, and diallyl phthalate has crucial status especially.
The general working method that adopts of diallyl phthalate is: phthalic anhydride generates the phthalic acid sodium salt with the liquid caustic soda reaction, again with chloropropene esterification and get bullion under 40-60 ℃, negative pressure.In actual production process, the staff need carry out sample detecting to product in order to grasp the degree of reaction.Traditional method of sampling generally is a directly collected specimens in the agitated reactor of staff.This method of sampling not only can not guarantee the randomness of gained sample, but also causes the reaction gas reactor to leak easily, has reduced product quality, also is unfavorable for that the staff's is healthy simultaneously.
The utility model content
The utility model technical matters to be solved provides the ST that is used for the diallyl phthalate production run; It is simple in structure; Convenient grab sample from agitated reactor in the diallyl phthalate production run, thus defective in the above-mentioned background technology eliminated.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
The ST that is used for the diallyl phthalate production run; It is characterized in that; Comprise the circulation pipe that is connected on the diallyl phthalate synthesis reactor, be arranged at the ebullator on the circulation pipe and be arranged at the ST body on the said circulation pipe; Said ST body comprises sampling container, and said sampling container is provided with sample tap.
As a kind of improvement, said sample tap is provided with capping.
As a kind of improvement, said sampling container is a cylinder, and said cylinder lower end has the transition part of taper.
As a kind of further improvement, said sampling container utilizes flange to be connected with valve.
As a kind of improvement, said circulation pipe is provided with tensimeter.
As a kind of improvement, said circulation pipe is provided with the head tank that is used to cushion.
The course of work of the utility model is following: before the sampling; At first open the valve of sampling container; And the ON cycle pump, make material and the interior material realization of synthesis reactor circulation in the circulation pipe, after circulation a period of time; The interior material of material and synthesis reactor reaches consistance in the circulation pipe, has just guaranteed the randomness of sampling; Then, open capping, utilize clamper clamping sampling jar to stretch into collected specimens in the said sampling container, collection is closed capping after accomplishing.
Because this reaction is a negative reaction; Therefore the pressure of synthesis reactor is lower than atmosphere outside and presses, and it is shorter to open capping time of sampling container, and material can not be leaked in the air yet; Thereby avoided environmental pollution, also reduced the contamination of products that causes in the sampling process to greatest extent.
Owing to adopted technique scheme, the beneficial effect of the utility model is:
The ST that the utility model provides; Be applicable to collected specimens in the diallyl phthalate production run; Circulation pipe is installed on synthesis reactor, on circulation pipe, is installed sampling container simultaneously, utilize ebullator to make material between synthesis reactor and circulation pipe, realize circulation; Thereby guaranteed the consistance of material between synthesis reactor and the circulation pipe, guaranteed the randomness of collected specimens.
The sample tap of the sampling container of the utility model is provided with capping, can when not taking a sample, sample tap be sealed, and prevents material from leakage, has improved operating personnel's working environment.
In addition, sampling container is a cylinder, and the cylinder lower end has the transition part of taper, and utilizes flange to be connected with valve, and the sampling container of this structure can directly be connected on the circulation pipe, maintenance is installed conveniently.
Simultaneously, for the security that guarantees to operate, circulation pipe is provided with tensimeter.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing; The ST that is used for the diallyl phthalate production run; Comprise the circulation pipe 2 that is connected on the diallyl phthalate synthesis reactor 1, be arranged at the ebullator 3 on the circulation pipe 2 and be arranged at the ST body 4 on the said circulation pipe 2; Said ST body 4 comprises sampling container 5, and said sampling container 5 is provided with sample tap 6.
In the present embodiment, said sample tap 6 is provided with capping 7, can prevent material from leakage with sample tap 6 sealings when not taking a sample, and has improved operating personnel's working environment.In addition, said sampling container 5 is a cylinder, and said cylinder lower end has the transition part of taper.Said sampling container 5 utilizes flange to be connected with valve 8.Sampling container 5 directly is connected on the circulation pipe 2, maintenance is installed conveniently.For the security that guarantees to operate, said circulation pipe 2 is provided with tensimeter 9.
Describe the course of work of the utility model in detail below in conjunction with accompanying drawing.
Before the sampling, at first open the valve 8 of sampling container 5, and ON cycle pump 3; Make material and synthesis reactor 1 interior material realization circulation in the circulation pipe 2; After circulation a period of time, material and synthesis reactor 1 interior material reach consistance in the circulation pipe 2, have just guaranteed the randomness of sampling; Then, open capping 7, utilize clamper clamping sampling jar to stretch into collected specimens in the said sampling container 5, collection is closed capping after accomplishing.
