Level switch mounting structure for confirmation raw material inputs of a liquid or minute three-dimensional state

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level switch installation structure for managing the storage state of a raw material stored in a solution storage tank or a powder storage tank, The present invention relates to a level switch installation structure for confirming a feed amount of a raw material in a liquid or particulate state in which a reaction according to the presence or absence of a raw material is accurately performed using a contact type switch that is turned off.In the present invention, the switch mounting hole 102 is formed on one side of the main body 10 constituting the tank or hopper in which the raw material is contained. The rear surface 204 is concave at the ce and has a front surface 202, And a rubber plate 20 having a coupling surface 206 formed on its periphery so that the front surface 202 is inserted into the switch installation hole 102 from outside to inside, And a fixing bracket 30 having the switch mounting portion 302 is attached to the rear surface 204 of the rubber plate 20. The mounting bracket 30 is mou on the rear surface 204 of the rubber plate 20, And the limit switch 40 is constituted so that the end portion of the operation arm 402 is fixed to the switch mounting portion 302 so as to be positioned near the ce of the rear surface 204 of the rubber plate, The switch case 50 is coupled and fixed to the rear side of the battery 30, It is configured to fetch a signal line to the outside of the switch case 50.
