Title:
OVALITY MEASUREMENT SENSOR AND METHOD FOR PRODUCING CEMENT
Document Type and Number:
Japanese Patent JP2020169762
Kind Code:
A
Abstract:
To provide an ovality measurement sensor capable of securely measuring the deformation volume of a rotary furnace, and a method for producing cement.SOLUTION: An ovality measurement sensor comprises: a pair of first magnets fixable at intervals in the circumferential direction of the cylindrical outer circumferential face of a rotary furnace; a deformation plate suspended between both the first magnets and elastically deformable; a first support member fixed to the deformation plate between both the first magnets, and fixed to the rotary furnace and supporting the deformation plate when both the first magnets are fixed to the rotary furnace; a strain gauge provided at the surface of the deformation plate and detecting the strain value of the deformation plate; a control part measuring the strain value of the strain gauge and further performing communication with external apparatus; an elastically deformable accessory plate arranged so as to be confronted with the deformation plate and also fixed to both the first magnets and the first support member; and a pair of second support members fixed at positions confronted with the first magnets in the accessory plate, capable of moving the deformation plate in the suspension direction of the deformation plate and also regulating the deformation other than elastic deformation in a direction orthogonal to the surface of the deformation plate following the cylindrical outer circumferential face of the rotary furnace so as to be supported.SELECTED DRAWING: Figure 1
