Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a feeding device for expanded perlite production. Background Art

[0002] Expanded perlite is a lightweight, porous inorganic non-metallic material, which is mainly formed by the rapid expansion of natural perlite ore after high-temperature rapid heating. It has good insulation, sound insulation, fireproof and other properties, and is widely used in construction, gardening, filtration, insulation and other fields.

[0003] Perlite ore usually needs to go through pre-treatment steps such as crushing and screening to ensure that the raw material particle size entering the feeding equipment is uniform and meets the requirements of subsequent processing. In the production process of expanded perlite, most of the materials are fed by conveyor belts, augers, etc. In the process of these devices conveying the stone, the feeding is often continuous. However, in actual production, in the operation of perlite production, it is sometimes necessary to feed the perlite indirectly and quantitatively, which can avoid perlite accumulation and improve production quality. Therefore, in the production process of perlite, in order to achieve indirect quantitative feeding, a feeding device for expanded perlite production is needed to solve the existing problems.

[0007] A telescopic push rod is also fixedly installed on the side wall of the quantitative box, and a connecting plate is hingedly installed at the telescopic end tail of the telescopic push rod. The connecting plate is fixedly connected to the outer side wall of the arc bottom plate, that is, the telescopic push rod drives the arc bottom plate to open and close through the connecting plate rod.

[0008] The conveying assembly includes a conveying box, on which a driving motor is fixedly installed on the side wall of one end of the conveying box. The output shaft of the driving motor is connected to a spiral conveying blade through a coupling and is located at the inner bottom of the conveying box. That is, the output shaft of the driving motor drives the spiral conveying blade to rotate, so that the stone inside the discharge box is transported to the quantitative box through the spiral conveying blade.

[0009] A support frame is also installed below the conveying assembly, on which a support plate is fixedly installed. The top of the support plate is a semicircular arc and is fixedly connected to the bottom of the conveying box, that is, the support plate supports the bottom of the conveying box.
