Description

Technical Field

[0001] The invention relates to the technical field of rotary kiln feed port equipment, in particular to a rotary kiln feed port. Background Art

[0002] In the metallurgical, chemical, coal, environmental protection and other industrial fields, solid furnace materials need to be heated, cooled or reacted in a closed space such as a rotating kiln. For example, a ring kiln for drying, a rotary hearth furnace for iron ore reduction or waste treatment, etc. Whether it is a ring kiln or a rotary hearth furnace, the chassis rotates, and the side walls and top of the kiln are fixed, so that the material can be fed from the top. A spiral discharger is installed at the bottom of the kiln and above the chassis to achieve fixed feeding and fixed discharge while the chassis rotates. However, the spiral discharger can only be used to discharge thin-layer paved materials. For thick layers of up to one meter or even several meters, the performance of the spiral discharger cannot meet the requirements.

[0003] The application number is CN201910958282.9, which discloses a rotary kiln, including a kiln body and a chassis, wherein a top cover is flexibly connected to the upper part of the kiln body, and a feed port is fixedly processed on the top cover; the kiln body and the chassis rotate simultaneously under the drive of the driving device, and the top cover is fixed and does not rotate; the side wall of the kiln body and the chassis are not completely in contact to form a discharge port; a discharge baffle is arranged outside the chassis, and the discharge baffle is independent of the chassis and fixed. The material falling from the feed port is discharged from the discharge port under the action of gravity and accumulated on the chassis. The discharge baffle scrapes the material accumulated on the periphery of the chassis from the chassis to achieve the purpose of discharge. The rotary kiln structure of the present invention can carry a material layer of up to several meters on the one hand, and can rotate the kiln on the other hand, which not only realizes fixed feeding and fixed discharge, but also solves the high material layer scene that the conventional spiral discharger cannot solve, and improves the efficiency of heating, cooling and reaction through rotation.

[0004] Although this setting solves the high material layer scenario that conventional spiral discharge machines cannot solve, and improves the efficiency of heating, cooling and reaction through rotation, when the staff feeds through the rotating kiln port of this setting, the temperature in the kiln rises when the raw materials are added for reaction, forming a heat wave that sprays out to the outside of the kiln port. If the staff moves away from the kiln port slowly, they may be burned by the heat wave. Summary of the invention

[0005] The object of the present invention is to provide a rotary kiln feed port to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a rotary kiln feed port, comprising a first shell, a second shell and a third shell, wherein the first shell, the second shell and the third shell are connected to each other and communicate with each other, the second shell is located between the first shell and the third shell, the third shell is located on the top of the second shell, and the first shell is located at the bottom of the second shell; An iris assembly is installed at the bottom port of the first housing, and a turntable assembly is installed inside the second housing; A guide rail is installed on the outer wall of the first housing, a transmission assembly is connected between the turntable assembly and the iris assembly, and the guide rail provides movement guidance for the operation of the transmission assembly; The turntable assembly includes a first turntable for transmission, a second push rod, a third connecting rod, a second turntable and a rotating shaft, and the turntable assembly also includes a rotating baffle for preventing heat waves from rising; The turning baffle and the iris assembly are in opposite states in terms of opening and closing the housing port; The purpose of this arrangement is that when the rotating baffle is opened, the iris assembly is closed, and the raw materials on the upper surface of the rotating baffle enter the tube body between the rotating baffle and the iris assembly; when the iris assembly opens and the rotating baffle is closed, the raw materials enter the interior of the furnace, and the rotating baffle seals and blocks the rising heat waves.
