Abstract

The utility model discloses a kind of culture medium bubble detection devices, for detecting bubble in culture medium pouring process, it includes laser emitter, laser pickoff, signal projector, lumen, loaded in filling piping line, when there are when bubble in the culture base-material of injection, laser pickoff can receive the illumination of laser emitter, then electric signal or other signals are issued to outside by signal projector, manually or automatically to exclude bubble, compared to pervious artificial range estimation, to exclude the substandard products of bubbles, not only accuracy is high, it is high-efficient, it also can be reduced the waste of culture medium, save cost, there is apparent progress.

Description

Culture medium bubble detection device

Technical field

The present invention relates to biological detection equipment field more particularly to a kind of it can detect bubble in culture medium shot process Device.

Background technique

Pre- filling agar medium is mainly used for the microorganism detection of clean environment, will appear gas once in a while in pouring process Bubble, cause product unqualified, need manually to visually inspect, time-consuming and laborious and result is inaccurate, underproof product abandon and Result in waste.

Summary of the invention

The utility model is directed to the problem of above-mentioned production process, joined bubble inspection in culture medium filling piping line Device is surveyed, whether with the presence of bubble, and after detecting bubble, to issue electric signal or wireless communication to outside in signal piping Number, the utility model structure includes: lumen, laser emitter, laser pickoff, signal generator；The laser emitter Transmitting terminal is loaded on the lumen wall, and lumen side on the other side is equipped with the receiving end of the laser pickoff；The laser Transmitter connects the laser pickoff, is fixed on the lumen outer wall；There is connection structure at the lumen both ends；The laser hair The transmitting terminal of emitter has several in parallel laser heads side by side, the diameter of laser head and the interior caliber equal to the lumen；Here It is described several the line of in parallel laser head side by side is perpendicular with lumen direction of both ends side by side.

Preferably, the connection structure is external screw thread or internal screw thread；

Preferably, the laser emitter is provided with battery；

Preferably, the laser pickoff includes photo resistance；

Preferably, there are several in parallel receiving ports opposite with the laser head in the receiving end；

Preferably, the signal generator issues wired electric signal or wireless signal to external system；

Preferably, the wired electric signal is transmitted to the opening and closing that relay controls production line or the wireless signal transmission extremely PLC controller.

The utility model main body is lumen, and there is screw thread at both ends, convenient for being loaded and unloaded in filling pipeline, using several laser Head is in parallel and corresponding with several receiving ports side by side, can more accurately detect the bubble being likely to occur in filling piping line, when there is bubble When appearance, laser pickoff receives optical signal, is converted into electric signal transmission to the signal generator, You Qixiang external system hair Perhaps wireless signal takes the open circuit perhaps device of starting exclusion bubble or artificial row to whole system to wired electric signal out Bubble removing, so that production efficiency improves, defect rate is reduced, and has saved cost, in the art, have apparent technology into Step.

Fig. 2 is the second visual angle of the utility model schematic diagram.

Specific embodiment

Embodiment one

As shown in Figure 1 and Figure 2, the utility model structure includes: lumen 1, laser emitter 2, laser pickoff 3, signal hair Raw device 4；The transmitting terminal of the laser emitter is loaded on 1 inner wall of lumen, and 1 side of lumen on the other side is equipped with the laser The receiving end of receiver 3；The laser emitter 3 connects the laser pickoff 4, is fixed on 1 outer wall of lumen；The pipe There is connection structure at 1 both ends of chamber；The transmitting terminal of the laser emitter 2 has 8 in parallel laser heads 5 side by side, the diameter of laser head 5 With the interior caliber for being equal to the lumen 1；Described 8 side by side the line of in parallel laser head 5 side by side be mutually to hang down with 1 direction of both ends of lumen Straight.

Preferably, the connection structure is external screw thread；

Preferably, the laser emitter 2 is provided with battery 6；

Preferably, the laser pickoff 3 includes photo resistance；

Preferably, there are 8 in parallel receiving ports opposite with the laser head in the receiving end.

Preferably, the signal generator is to external system wireless signal, the wireless signal transmission to PLC controller, After the signal receiving end of PLC controller receives the information for detecting bubble, by control terminal control material feeding rifle exhaust apparatus into Row exhaust, to exclude the influence that bubble generates product quality, material feeding rifle exhaust apparatus refers to the correlation function of orifice and rectal intestine endoscope, Prior art, there is no technical solution it is imperfect, the defect of insufficient disclosure.

The above is only the ranges that preferred embodiments of the present invention, the present invention that therefore, it cannot be limited according to are implemented, i.e., according to the present invention Equivalence changes made by description and decoration, all should belong to the present invention covering in the range of.
