Abstract
The utility model discloses a tunnel drying oven with a PLC control device, which includes a tunnel drying oven, wherein the PLC control device is mounted on the tunnel drying oven; a plurality of temperature sensors are mounted in the tunnel at intervals and connected with the PLC control device; and the PLC control device is connected with a hot blast valve. By connecting the temperature sensors with the PLC control device, the temperature detected at different positions in the tunnel are fed back to the PLC control device for monitoring the temperature of the tunnel drying oven; and by connecting the PLC control device with the hot blast valve, the opening degree of the hot blast valve is adjusted by comparing the detected temperature with the set temperature, as a result the temperature in the tunnel drying oven is kept constant, and the drying quality of a workpiece is ensured.
Description
Technical field
The utility model relates to a kind of tunnel baking oven, relates in particular to a kind of tunnel baking oven of the PLC of having control device.
Background technology
As everyone knows, the tunnel baking oven is to adopt long casing hot air circulation and far-infrared ray drying mode to carry out dry a kind of baking oven, mainly is in order to dry processing to a large amount of and the demanding workpiece of drying efficiency.The tunnel baking oven is the continous way drying plant, sustainable baking incessantly.Generally, workpiece is dried processing in import department gets into baking oven, and through the chain type track workpiece is transported from outlet, during continual baking of hot blast that be blown into through Hot-blast valve.In order to make the oven interior temperature constant, guarantee the dries quantity of workpiece, just must effectively regulate, but the air quantity of at present common tunnel baking oven to be regulated the Artificial Control that adopt more the hot blast rate that is blown into, its accuracy is relatively poor.
The utility model content
The purpose of the utility model is to provide a kind of tunnel baking oven of the PLC of having control device; It has solved the hot blast rate that the existing tunnel baking oven is blown into and has regulated inaccurate problem; Realized the hot blast rate that the tunnel baking oven is blown into is accurately regulated; Make the temperature constant of tunnel oven interior, guaranteed the dries quantity of workpiece.
The purpose of the utility model is to realize through following technical scheme:
A kind of tunnel baking oven with PLC control device; Comprise the tunnel baking oven, on the said tunnel baking oven PLC control device is installed, some temperature sensors are installed in the said tunnel at interval; And be connected with the PLC control device, said PLC control device is connected with Hot-blast valve.
Further, said PLC control device is installed in tunnel baking oven import department.
The beneficial effect of the utility model does; Said tunnel baking oven with PLC control device; It links to each other with the PLC control device through temperature sensor, and the detected temperature of diverse location in the tunnel is fed back to the PLC control device, has realized the tunnel temperature of oven is monitored; The PLC control device links to each other with Hot-blast valve, compares with design temperature according to detected temperature, the aperture of Hot-blast valve is regulated, thereby realized the constant of tunnel oven interior temperature, has guaranteed the dries quantity of workpiece.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the said structural representation with tunnel baking oven of PLC control device of the utility model;
Fig. 2 is the said principle schematic with PLC control device of the utility model.
Among the figure:
1, tunnel baking oven, 2, the PLC control device, 3, temperature sensor, 4, Hot-blast valve, 5, the tunnel.
The specific embodiment
As shown in Figure 1; In present embodiment, said tunnel baking oven with PLC control device comprises tunnel baking oven 1; On the said tunnel baking oven 1 PLC control device 2 is installed; At interval some temperature sensors 3 are installed in the said tunnel 5, and are connected with PLC control device 2, said PLC control device 2 is connected with Hot-blast valve 4.And said PLC control device 2 is installed in tunnel baking oven 1 import department.
During work; As shown in Figure 2, temperature sensor 3 is detected temperature inversion that the signal of telecommunication is transferred to PLC control device 2, and PLC control device 2 asks average to a plurality of temperature that receive; Compare temperature-averaging value that draws and desired temperature; And comparative result is converted into current signal, in order to the aperture of control Hot-blast valve 4, thereby reach thermostatically controlled purpose.
Said tunnel baking oven with PLC control device; It has solved the hot blast rate that the existing tunnel baking oven is blown into and has regulated inaccurate problem; Realized the hot blast rate that the tunnel baking oven is blown into is accurately regulated, made the temperature constant of tunnel oven interior, guaranteed the dries quantity of workpiece.
Claims (2)
