Abstract
The utility model discloses an automatic drying device, and belongs to the technical field of drying devices. The automatic drying device comprises a drying passageway, and an air inlet pipe is arranged above the drying passageway. The automatic drying device further comprises a valve and a pressure sensor, the valve is arranged in the air inlet pipe, the pressure sensor is arranged in the drying passageway, the valve is in electric connection with the pressure sensor, and the pressure sensor is in electric connection with a controller. The automatic drying device has the advantages that the pressure sensor is used for detecting air pressure inside the drying passageway, the controller controls the on-off status of the valve in the air inlet pipe according to the air pressure detected by the pressure sensor, and therefore the purpose of automatic drying is achieved.
Description
Technical field
The utility model relates to a kind of automatic drier, belongs to the drying plant technical field.
Background technology
Drying unit is to come material is dried by thermal current mostly, traditional drying unit all was constantly to pour thermal current in drying channel before oven dry is finished, because drying channel has not been hermetic, so too much thermal current is rushed in the drying channel, have unavoidably the phenomenon that thermal current overflows, this will certainly cause the wasting of resources, has increased production cost to enterprise virtually.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of automatic drier, automatically controls pouring of thermal current, economizes on resources.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automatic drier, comprise drying channel, the top of drying channel is provided with air inlet pipe, also comprise valve and pressure sensor, valve is arranged on air inlet pipe inside, and pressure sensor is arranged on drying channel inside, valve is electrically connected with pressure sensor, and pressure sensor is electrically connected with controller.
Controller is the PLC controller.
The beneficial effects of the utility model are: detect air pressure in the drying channel by pressure sensor, with this switch by controller control air inlet pipe internal valves, realize the purpose of auto-drying.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, drying channel, 2, air inlet pipe, 3, valve, 4, pressure sensor.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, this automatic drier, comprise drying channel 1, the top of drying channel 1 is provided with air inlet pipe 2, also comprise valve 3 and pressure sensor 4, valve 3 is arranged on air inlet pipe 2 inside, and pressure sensor 4 is arranged on drying channel 1 inside, valve 3 is electrically connected with pressure sensor 4, and pressure sensor 4 is electrically connected with controller.The air pressure that the pressure sensor 4 of drying channel 1 inside detects in the drying channel 1, when the atmospheric pressure value that detects during less than predefined atmospheric pressure value, pressure sensor 4 can be to signal of controller, controller can by-pass valve control 3 be opened, and air inlet pipe can be rushed thermal current to drying channel 12 this moments, when the atmospheric pressure value that detects during greater than predefined atmospheric pressure value, controller can cut out by by-pass valve control 3, with this purpose that realizes auto-drying, saved resource, reduced production cost.
Stability when working in order to satisfy controller, controller is the PLC controller.
