Abstract
Description
Technical Field
[0001] This utility model relates to the field of acetylene production technology, and in particular to an intermittent feeding device for an acetylene generator. Background Technology
[0002] Currently, the calcium carbide acetylene process is the main method for acetylene production, which is mainly divided into two categories: wet acetylene and dry acetylene. The wet acetylene production process has problems such as high industrial water consumption, high cost of calcium carbide slag slurry treatment, difficulty in comprehensive utilization of wet calcium carbide slag, and the generation of new waste gas pollution from the reuse of calcium carbide slag clear liquid. Therefore, some acetylene producers have begun to adopt the dry acetylene process, which greatly reduces water consumption and produces dry powdery calcium carbide slag that can be directly and widely used in cement production and flue gas desulfurization.
[0003] Whether using wet or dry methods for acetylene production, traditional feeding devices generally suffer from poor sealing during the process of calcium carbide entering the acetylene generator. This can easily lead to acetylene and water vapor backflow into the calcium carbide buffer silo, potentially causing safety accidents in the feeding system. Existing methods introduce nitrogen as an inert gas into the sealed cavity and silo of the feeding device to create a positive pressure environment, preventing acetylene gas from seeping in and diluting leaked flammable gases to reduce the risk of explosion. However, this cannot guarantee a continuous and uniform supply of calcium carbide, which can make the reaction within the acetylene generator unstable, reduce the reaction efficiency of calcium carbide, and affect the yield of acetylene. Furthermore, the instability of the reaction leads to fluctuations in product quality, which is detrimental to subsequent production and processing. Utility Model Content

A threaded transport disc is fixedly connected to the outer wall of the rotating column, and a conical discharge port is fixedly connected to the right edge of the pipe.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, after the calcium carbide raw material enters the pipeline, the motor is started so that the output shaft drives the rotating disk on the outer wall to rotate. The rotating disk and the four open wheel at the bottom are engaged and connected. When the rotating disk rotates one revolution, the four open wheel rotates one-quarter revolution. It is used in conjunction with the threaded conveyor disk on the right side to feed the material, so as to achieve the effect of intermittent feeding. This allows the user to control the feeding time and amount according to the reaction situation in the acetylene generator, so as to avoid over-supply or under-supply of calcium carbide.
[0022] 2. In this utility model, calcium carbide is placed in the trapezoidal outer shell at the top. The second motor is started, which drives the meshing bevel gear one to rotate, causing the rotating column two to rotate as well. The half gear on the outer wall causes the meshing toothed frame to move up and down, which in turn drives the bottom screen to move up and down, achieving a vibration effect. This screens out large particles from the calcium carbide, while small particles fall into the bottom device, making the reaction with acetylene more uniform. Attached Figure Description

[0039] Working principle: After the calcium carbide raw material enters the pipe 201, the motor 203 is started, which causes the output shaft 204 to drive the rotating disk 2051 on the outer wall to rotate. The rotating disk 2051 and the four-open wheel 2052 at the bottom are engaged and connected. When the rotating disk 2051 rotates one revolution, the four-open wheel 2052 rotates one-quarter revolution. It works in conjunction with the threaded conveyor disk 2072 on the right side to feed the material, achieving the effect of intermittent feeding. This allows the user to control the feeding time and amount according to the reaction situation in the acetylene generator, avoiding over-supply or under-supply of calcium carbide.
[0040] Calcium carbide is placed in the trapezoidal outer shell 301 at the top. The motor 302 is started, which drives the meshing bevel gear 303 to rotate, causing the rotating column 305 to rotate as well. The half gear 3061 on the outer wall causes the meshing toothed frame 3062 to move up and down, which in turn drives the bottom screen 3071 to move up and down, achieving a vibration effect. This screens out large particles from the calcium carbide, while small particles fall into the bottom device, making the reaction with acetylene more uniform.
