Abstract
Disclosed is a temperature measuring device of a vacuum dampening machine for tobacco. The temperature measuring device of the vacuum dampening machine for the tobacco comprises a connecting pipe, an internal flange and an external flange, wherein the internal flange and the external flange are respectively arranged at two ends of the connecting pipe. A water leakage hole is formed at the bottom of the connecting pipe. A water storage pipe is arranged between the internal flange and the external flange, and the water storage pipe is corresponding to the water leakage hole. A through hole, corresponding to the water storage pipe, is formed at the bottom of the external flange. The outside of the through hole is connected with a sleeve which is horizontally arranged. A temperature sensor is installed in the sleeve, wherein one end of the temperature sensor extends to the through hole and the water storage pipe. The temperature sensor is connected with the end portion of the sleeve in a closed mode. A transparent observing window is arranged on the outer side of external flange by a gland method. The temperature measuring device of the vacuum dampening machine for the tobacco is simple in structure. Due to the fact that the temperature sensor is horizontally arranged, the temperature sensor can be completely soaked so long as a micro amount of water exists at the bottom of the water storage pipe, and detecting accuracy of temperature inside the vacuum dampening machine can be effectively improved. After the temperature measuring device of the vacuum dampening machine for the tobacco is used, by comparison, vacuum-pumping time of a vacuum pump is reduced from original duration of maximum 10 minutes to 4 minutes, and a dampening effect of tobacco leaves is stable.

Technical field
The invention belongs to vacuum pre-conditioner for tobacco temperature testing equipment technical field, particularly a kind of vacuum pre-conditioner for tobacco temperature-detecting device.
Background technology
At cigarette industry, tobacco is an airtight space with the injecting type vacuum conditioner when working, the vacuum pump that links to each other with it utilizes the Venturi tube principle by water vapour the air in the vacuum conditioner to be released, when the vacuum tightness of vacuum conditioner inside reaches 1066Pa, vacuum pump quits work, this moment, steam humidification system was from the inner humidification water that adds of trend vacuum conditioner, for the tobacco leaf of inside provides the humidification water.
At present, vacuum degree of vessel checkout equipment or apparatus expensive or detect inaccurately because vacuum degree of vessel becomes certain proportionate relationship with the temperature of internal tank, can become the temperature conversion in the container operation of vacuum tightness opertaing device in actual use.But in the very low situation of vacuum degree of vessel, inner transmitter also seldom can not detect the temperature of internal tank well with present conventional temperature testing equipment.
For this reason, vacuum conditioner is by the vacuum tightness that converts of the water temperature in the inspection instrument.Under normal circumstances, water is arranged in the snubber assembly of vacuum conditioner all the time, this part water stays when being last working cycle, temperature sensor is immersed in the water, so that the normal conduction of temperature, in the very low situation of the vacuum tightness of vacuum conditioner inside, this part water enters in the vacuum conditioning box body by the connected entrance evaporation, even all evaporations, only remain the end that seldom a part of water soaking temperature sensor, the temperature of vacuum conditioner inside can accurately not be detected, and has affected normal production.
In addition, in above-mentioned use procedure, owing to temperature detection inaccurate (higher) often occurs, although the practical vacuum degree of vacuum conditioner inside has reached designing requirement, but vacuum pump can not in time stop, and can't carry out further work, has affected normal production.
Summary of the invention
But the invention provides a kind of simple in structure, humidification effect stability of tobacco leaf and the vacuum pre-conditioner for tobacco temperature-detecting device of Effective Raise accuracy in detection.
For achieving the above object, technical scheme of the present invention is: a kind of vacuum pre-conditioner for tobacco temperature-detecting device, the inner flange and the outside flange dish that comprise connecting pipe and connecting pipe two ends, the connecting pipe bottom is provided with leaking hole, is provided with the standpipe corresponding with leaking hole between inner flange and the outside flange dish; The outside flange tray bottom is provided with the through hole corresponding with standpipe, and through hole is externally connected to horizontally disposed sleeve pipe, and the temperature sensor that an end stretches into through hole and standpipe is installed in the sleeve pipe, and temperature sensor is connected with cannula tip is airtight; The outside flange dish outside is provided with transparent windows by gland flange.
Described gland flange bottom is provided with bushing slot, and sleeve pipe passes bushing slot.
Described cannula tip is provided with threeway, and threeway is connected by end cap with temperature sensor; The threeway other end is provided with plug.
Be respectively equipped with O-ring seal between described transparent windows and outside flange dish, transparent windows and the gland flange.
Compared with prior art, advantage of the present invention is:
1, the present invention includes inner flange and the outside flange dish at connecting pipe and connecting pipe two ends, the connecting pipe bottom is provided with leaking hole, is provided with the standpipe corresponding with leaking hole between inner flange and the outside flange dish; The outside flange tray bottom is provided with the through hole corresponding with standpipe, and through hole is externally connected to horizontally disposed sleeve pipe, and the temperature sensor that an end stretches into through hole and standpipe is installed in the sleeve pipe, and temperature sensor is connected with cannula tip is airtight; The outside flange dish outside is provided with transparent windows by gland flange, it is simple in structure, because temperature sensor is for being horizontally disposed with, have just complete soaking temperature sensor of Trace water bottom the standpipe, but the accuracy in detection of Effective Raise vacuum conditioner internal temperature; After the present invention used, through relatively learning, the vacuum pump pumpdown time reduced to 4 minutes by the longest 10 minutes originally, the humidification effect stability of tobacco leaf.
2, the outside of ring flange is provided with transparent windows by gland flange outside, and transparent windows is tempered glass, is used for observing the water level situation in connecting pipe and the standpipe; Be respectively equipped with O-ring seal between transparent windows and outside flange dish, transparent windows and the gland flange, to improve the sealing structure performance, reduce the moisture evaporation.
3, cannula tip is provided with threeway, and threeway is connected by end cap with temperature sensor; The threeway other end is provided with plug, because connecting pipe, standpipe and inside pipe casing are hermetically-sealed construction, need to unload plug periodic cleaning is carried out in inside, again load onto plug after having cleaned, can effectively prevent connecting pipe, standpipe and sleeve scaling, obstruction, assurance equipment can use continuously.
