Abstract
The utility model relates to a safe and rapid sampling device. The device comprises a lifting device, a glass tube sight glass and a first ball valve sequentially from top to bottom, wherein the lifting device comprises a tubular case as well as a spindle and a crank which are arranged in the case, one end of the case is sealed, one end of the spindle is fixed on the inner wall of the case through a spindle sleeve, and the other end of the spindle extends out of the case to be connected with the crank. The device is simple in structure and convenient to operate, and sampling can be performed without a series of operations such as cooling, emptying and the like during sampling, so that the operation time in the chemical production is saved greatly; steps of cooling, heating and the like are omitted, so that a large amount of energy is saved, technological parameters of reactions cannot be changed due to sampling processes, and reaction processes can be controlled more easily.
Description
Technical field
The utility model relates to a kind of Chemical Manufacture instrument, is specifically related to one sampler safely and fast.
Background technology
At present in the chemical industry workshop such as organic synthesis, all adopt reactor prepare burden and react, in course of reaction, conventionally need to constantly sample, then detect by the means such as gas chromatographic analysis, liquid-phase chromatographic analysis, determine whether reactant liquor meets standard, according to testing result, reactant liquor is carried out next step processing.
But, in organic synthesis, conventionally adopt organic solvent, if toluene, ethylene dichloride, tetrahydrofuran, dimethyl sulfoxide (DMSO) etc. are as solvent, and reaction is carried out under uniform temperature, pressure, when sampling, in order to ensure safety, need to first lower the temperature, adjust the operations such as still internal pressure, then open sample tap to sample, this sampling mode is wasted a large amount of time and the energy, and in the time of sampling, organic solvent high volatility, inevitably can be evaporated by sample tap, and workman is caused to injury to a certain degree.
Utility model content
The utility model provides a kind of sampler safely and fast simple in structure, simple to operate, convenient to use.
The utility model adopts following technical scheme:
The utility model from top to bottom comprises successively draws together lifting gear, glass tube visor and the first ball valve, described lifting gear is fixedly connected with glass tube visor one end by connecing soon clip, and the described glass tube visor other end is fixedly connected with by connecing soon clip with one end of the first ball valve;
Described lifting gear comprise one end sealing tubular shell, be arranged on rotating shaft and crank in housing, described rotating shaft one end is fixed on by axle sleeve on the inwall of housing, the other end stretches out housing and is connected with crank.
As further improvement of the utility model, between described rotating shaft and housing, be provided with O-ring seal.
As further improvement of the utility model, the first described ball valve lower end is provided with the second ball valve, and described the first ball valve is fixedly connected with by connecing soon clip with the second ball valve.
Good effect of the present utility model is as follows:
The utility model is simple in structure, easy to operate, in the time of sampling, do not need first can sample by a series of operations such as cooling, emptying, greatly save the running time in Chemical Manufacture, the steps such as cooling intensification are cancelled, save a large amount of energy, can, because of the technological parameter of the process change reaction of sampling, course of reaction more easily not controlled.
The utility model is provided with O-ring seal and two valves, and the leakproofness of assurance device is safe and reliable when sampling, greatly reduces the injury that in sampling process, organic volatilization causes workman.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model lifting gear.
In the accompanying drawings: 1 lifting gear, 11 housings, 12 cranks, 13 O-ring seals, 14 axle sleeves, 15 rotating shafts, 2 glass tube visors, 3 first ball valves, 4 second ball valves, 5 connect clip, 6 messenger wires, 7 sampling jars soon.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The sampler safely and fast of one as shown in Figure 1, it comprises lifting gear 1, glass tube visor 2, the first ball valve 3 and the second ball valve 4 from top to bottom successively, described lifting gear 1 is fixedly connected with glass tube visor 2 one end by connecing soon clip 5, described glass tube visor 2 other ends are fixedly connected with by connecing soon clip 5 with one end of the first ball valve 3, and the other end of described the first ball valve 3 is fixedly connected with by connecing soon clip 5 with one end of the second ball valve 4.
As shown in Figure 2, described lifting gear 1 comprises the tubular shell 11 of one end sealing and is arranged on the rotating shaft 15 in housing 11, described rotating shaft 15 one end are fixed on by axle sleeve 14 on the inwall of housing 11, the other end stretches out housing 11 and is connected with crank 12, between described rotating shaft 15 and housing 11, be provided with O-ring seal 13, be used for making device airtight, and can bear certain pressure.
On the kettle cover of reactor, conventionally have many mouthful, for charging, emptying etc., in use use less than hole use blind plate sealing.While using this device, be fixedly connected with hole for subsequent use or thief hole on reactor by the lower end of the second ball valve 4 in advance, in not sampling, make the first ball valve 3 and the second ball valve 4 in closed condition, in safety and still, seal ensureing.
When sampling, as shown in Figure 2, one end of messenger wire for sampling 6 is fixed on to rotating shaft 15, a sampling jar 7 is tied up in one end, rotating crank 12 is wrapped in rotating shaft 15 messenger wire 6, then by connecing soon clip 5, lifting gear 1 is fixed on glass tube visor 2, open the first ball valve 3 and the second ball valve 4, by rotating crank 12, decontrol messenger wire 6, that sampling jar 7 enters in reactor, stop a moment, then by rotating crank 12, sampling jar 7 is mentioned, then close the first ball valve 3 and the second ball valve 4, observe in sampling jar 7, whether to get appropriate sample by glass tube visor 2, if need to resample, repeat aforesaid operations, if got appropriate sample in sampling jar 7, the clip 5 that connects soon between the first ball valve 3 and the second ball valve 4 is opened, the partial devices of taking off is taken to ventilation, slowly open the first ball valve 3, inner gas is discharged, then take out sampling jar 7, complete the process of primary sample.
