Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, specifically relating to a device for preparing calcium aluminate steelmaking refining agent. Background Technology

[0002] Calcium aluminate steelmaking refining agent is mainly produced from raw materials such as bauxite and limestone. During production, the bauxite and limestone need to be crushed and mixed. The size and uniformity of the raw material particles directly affect the reaction effect and efficiency, ultimately impacting the quality of the calcium aluminate steelmaking refining agent. Therefore, the crushed raw materials need to be screened to ensure the size and uniformity of the particles. Existing technologies mostly use flat screens for screening, which have poor screening effect and low efficiency, hindering production. Therefore, there is an urgent need for a calcium aluminate steelmaking refining agent preparation device to solve the above technical problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a preparation device for calcium aluminate steelmaking refining agent, including a screening box with an opening at the top and a discharge pipe at the bottom. A V-shaped filter cylinder is provided inside the screening box, with rotating shafts connected to both ends of the filter cylinder. The two rotating shafts are rotatably connected to the inner wall of the screening box through bearings. One of the rotating shafts passes through the screening box and is connected to a motor. The filter cylinder is covered with filter holes, and an inlet and outlet are provided at the center of the filter cylinder. An openable and closable material cover is provided at the inlet and outlet. During feeding, the inlet and outlet face upwards, directly opposite the opening at the top of the screening box. Open the material cover and place the material to be screened into the filter cylinder. After closing the material cover, the motor drives the filter cylinder to rotate and screen the material. Because the filter cylinder is V-shaped, the material can move up and down and left and right in the filter cylinder during rotation, making the screening more efficient and thorough. The screened fine material is discharged from the discharge pipe and transferred to the next process. After screening, open the material cover, and the motor drives the filter cylinder to rotate, so that the inlet and outlet face downwards. The coarse material is discharged from the inlet and outlet and discharged out of the screening box through the discharge pipe.

[0004] Preferably, the material cover is threadedly connected to the inlet and outlet.

[0005] Preferably, a blowing assembly is provided above the filter cartridge. The blowing assembly includes a conduit and nozzles. A liquid pump or air pump is provided on the conduit to introduce high-pressure gas or water into the conduit. Multiple nozzles are evenly arranged along the length of the conduit and are connected to the conduit, with the spray direction of the nozzles facing the filter cartridge. The blowing assembly can perform blowing operations on the filter cartridge to avoid clogging after long-term use. High-pressure air or water can be introduced into the conduit for efficient cleaning of the filter cartridge.

[0006] Preferably, the opening of the screening box is provided with a removable cover, the conduit is fixed to the cover, and the nozzle passes through the cover and faces the filter cartridge. The cover reduces dust overflow from the screening box during screening operations.

[0007] Preferably, the guide tube is disposed inside the screening box, and one end of the guide tube is connected to a horizontal telescopic sleeve. The telescopic sleeve includes an outer tube and an inner tube. The outer tube is fixed to the screening box, and one end of the inner tube is always slidably located inside the outer tube. Specifically, a slider is fixedly connected to one end of the inner tube extending into the outer tube. A groove is provided on the inner wall of the outer tube corresponding to the slider, and the slider is slidably disposed in the groove. The other end of the inner tube extends out of the outer tube and is fixedly connected to one end of the guide tube. The other end of the guide tube is connected to a horizontal telescopic rod, which is an electric push rod or a hydraulic rod. The maximum extension distance of the telescopic rod is not less than the horizontal distance between two adjacent nozzles. The guide tube is connected to a spring tube. The extension and retraction of the telescopic rod pushes the guide tube to move back and forth, making the spraying range of the nozzles more comprehensive and avoiding blind spots in the cleaning of the filter cartridge due to the distance between the nozzles.

[0008] Preferably, the rotating shaft at one end of the filter cartridge is a feed pipe. One end of the feed pipe passes through the screening box and is connected to a feeding auger. The feed pipe and the discharge end of the feeding auger are rotatably connected by a bearing. The feeding auger is fixed by a bracket, and the feed end of the feeding auger is connected to a feed hopper. This configuration allows for the continuous feeding of material to be screened into the filter cartridge, improving the continuity and efficiency of screening.

[0009] This invention also includes other components that enable the preparation device for calcium aluminate steelmaking refining agent to function normally, such as control components for the feeding auger, nozzles, motors, and feed ducts (e.g., air or liquid pumps), control components for electric actuators, and control components for hydraulic rods, all of which are conventional technologies in the field. Furthermore, devices or components not specified in this invention, such as supports, feeding augers, electric actuators, hydraulic rods, and nozzles, all employ conventional technologies and equipment in the field.

[0010] Working principle: The material to be screened is placed in the filter cylinder, and the motor drives the filter cylinder to rotate to screen the material. Since the filter cylinder is V-shaped, the material can move up and down and left and right in the filter cylinder during the rotation, making the screening more efficient and thorough. The screened fine material is discharged from the discharge pipe and transferred to the next process. After screening is completed, the material cover is opened, the motor drives the filter cylinder to rotate, so that the inlet and outlet face downwards, and the coarse material is discharged from the inlet and outlet and discharged out of the screening box through the discharge pipe.

[0011] After a period of use, the filter cartridge can be blown by the blowing assembly to prevent the filter pores from becoming clogged.

[0012] The present invention has the following beneficial effects: during the screening process, the material moves up and down and left and right inside the filter cylinder, which improves the screening effect and screening efficiency; it is convenient to clean the filter cylinder, reduces filter hole clogging, and does not affect the next screening.
