Description
Technical field
The utility model relates to a kind of sampler, particularly relates to a kind of robotization vacuum sampling device, belongs to chemical reactant sampling utility appliance field.
Background technology
In polyester resin production process, need constantly to carry out real time sample detection to the vibrin in reactor.When reactor be in vacuumize state time, first release, cooling, then open valve or from other entrance feedings, understand the vacuum tightness that directly affect in reactor like this, affect product quality, and inconvenient operation, waste time and energy.
Therefore, how realizing carrying out sampling when not destroying reactor tightness and vacuum tightness and detect, is the technical matters that this area needs solution badly.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provides a kind of efficient robotization vacuum sampling device easy and simple to handle.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of robotization vacuum sampling device, comprise urceolus and motor, its special character is, charging aperture is provided with above described urceolus, discharging opening is provided with below urceolus, described outer barrel slidably connects piston, and described piston is provided with sampling groove, and described sampling groove is the radial direction through hole be arranged on piston; Described piston side is fixedly connected with screw rod, and described motor internal is provided with tapped rotor, and described rotor is socketed in outside described screw rod, and the internal thread of described rotor is meshed with the external thread of screw rod; Described piston is provided with charging position of rest and discharging position of rest, and described charging position of rest is that sampling groove is corresponding with charging aperture, and described discharging position of rest is that sampling groove is corresponding with discharging opening.
The beneficial effects of the utility model are: vacuum sampling device of the present utility model achieves the on-line monitoring of vibrin, avoid and destroy the product quality problem that in reactor, vacuum tightness and reaction environment cause, and efficiently easy and simple to handle, realize automated production sampling.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described outer barrel is provided with limiting plate, and described piston is provided with the projection matched with limiting plate.
The beneficial effect of above-mentioned further scheme is adopted to be avoid piston arbitrarily to roll in urceolus.
Further, described urceolus outside is provided with heating jacket.
Adopt the beneficial effect of above-mentioned further scheme to be that in reactor, temperature of charge is up to 260 DEG C, if urceolus outside does not have heating jacket, the sample of thickness enters after urceolus can very fast cooled and solidified, thus causes material cannot flow out from discharging opening.

In figure, 1, urceolus; 2, charging aperture; 3, discharging opening; 4, piston; 5, sampling groove; 6, screw rod; 7, rotor; 8, motor; 9, limiting plate; 10, protruding.
Embodiment
Be described principle of the present utility model and feature below in conjunction with example, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of robotization vacuum sampling device, comprise urceolus 1 and motor 8, its special character is, charging aperture 2 is provided with above described urceolus 1, discharging opening 3 is provided with below urceolus 1, described urceolus 1 internal slide is connected with piston 4, and described piston 4 is provided with sampling groove 5, and described sampling groove 5 is for being arranged on the radial direction through hole on piston 4; Described piston 4 side is fixedly connected with screw rod 6, and described motor 8 inside is provided with tapped rotor 7, and described rotor 7 is socketed in outside described screw rod 6, and the internal thread of described rotor 7 is meshed with the external thread of screw rod 6; Described piston 4 is provided with charging position of rest and discharging position of rest, and described charging position of rest is that sampling groove 5 is corresponding with charging aperture 2, and described discharging position of rest is that sampling groove 5 is corresponding with discharging opening 3.
Described urceolus 1 inside is provided with limiting plate 9, and described piston 4 is provided with the projection 10 matched with limiting plate 9.
The utility model uses like this, is arranged on by vacuum sampling device bottom reactor, piston 4 is in discharging position of rest, ensures that material in reactor can not flow out.During sampling, control motor 8 and drive screw rod 6 rotating linear motion to the right, pull piston 4 to charging position of rest, sampling groove 5 corresponding with charging aperture 2 (as shown in Figure 1); After sampling groove 5 fills up by material in reactor, control motor 8 and drive screw rod 6 rotating linear motion left, promote piston 4 to discharging position of rest, sampling groove 5 corresponding with discharging opening 3 (as shown in Figure 2), material is released, thus realizes automatic online sampling.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
