Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a vibrating screening device for castable refractory. Background Technology

[0002] Castable refractory is a granular and powdered material made of refractory materials, with the addition of a certain amount of binder and water. It has high fluidity, is suitable for construction by casting, and is an unshaped refractory material that can harden without heating. It is composed of refractory aggregates, powders, binders, additives, water or other liquid materials. During the processing of castable refractory, the crushed materials need to be separated into granules of different particle sizes according to particle size.

[0003] In existing technologies, vibrating screens are commonly used to screen castables. During screening, the mesh size of the vibrating screen needs to be adjusted according to the gradation requirements. Currently, traditional vibrating screens have fixed mesh levels. To meet the screening requirements of multiple gradations, multiple vibrating screen devices need to work together, resulting in a large investment in equipment and low screening efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vibrating screening device for castable refractory.

[0005] The technical solution of this utility model is as follows: a vibrating screen for castable refractory, comprising a shell, a vibrating screen assembly disposed inside the shell, and a drive component disposed on the outer wall of the shell and providing power to the vibrating screen assembly; a feed inlet is provided at the top of the shell, and a first collection hopper is provided at the lower end of the outer wall of the shell;

[0006] The vibrating screen assembly includes arc-shaped brackets symmetrically arranged on both sides inside the housing and an arc-shaped screen that is slidably engaged with the two arc-shaped brackets; the arc-shaped screen is slidably engaged with the arc-shaped brackets by a locking block, and a toothed rack is provided on the outer wall of the arc-shaped screen; a return spring is provided on the arc-shaped bracket to abut against the locking block.

[0007] The driving component includes a linkage shaft that runs through the side wall of the housing and a drive motor that is located on the outer side wall of the housing and provides power to the linkage shaft; an incomplete gear that meshes with a rack is sleeved on the linkage shaft.

[0008] Furthermore, several vibrating screen assemblies are provided, and each vibrating screen assembly is equidistantly distributed inside the shell from top to bottom; the mesh diameter of the arc-shaped screen corresponding to each vibrating screen assembly decreases sequentially; the number of driving components corresponds to the number of vibrating screen assemblies; a second collection hopper is provided on the outer wall of the shell at a position corresponding to each arc-shaped screen.

[0009] Note: By setting up multiple vibrating screen components, this utility model can classify and screen castables according to usage requirements, which helps to improve the ease of use of the equipment.

[0010] Furthermore, a swing shaft is provided inside the shell and above each arc-shaped screen, and a scraper plate is fitted on each swing shaft to abut against the arc-shaped screen at the corresponding position.

[0011] Note: During the vibration of the arc-shaped screen, the scraper is used to turn over the refractory material on the upper surface of the arc-shaped screen, which helps to improve the refractory material discharge efficiency.

[0012] Furthermore, the swing shaft is rotatably engaged with the housing, one end of the swing shaft passes through the housing and is connected to a small gear; a rack frame is slidably engaged on the outer wall of the housing and simultaneously meshes with each small gear; a push ring is connected to the rack frame; an auxiliary motor is provided on the outer wall of the housing, and the output end of the auxiliary motor is connected to a swing cam that is movably engaged with the push ring.

[0013] Explanation: The auxiliary motor drives the oscillating cam to rotate. The engagement between the oscillating cam and the push ring causes the rack frame to move back and forth on the outer wall of the housing. This causes the oscillating shaft to drive the scraper to oscillate back and forth above the corresponding arc-shaped screen, preventing the accumulation of casting material on the arc-shaped screen and improving the working efficiency of the equipment.

[0014] Furthermore, a gearbox is provided on the outer wall of the housing, and the pinion, rack frame and auxiliary motor are all located inside the gearbox; the drive motor is located on the outer wall of the gearbox.

[0015] Note: Utilizing the gearbox to protect the pinion and rack frame during travel improves the safety of the equipment.

[0016] Furthermore, the bottom end of the scraper is provided with actuating teeth, and the scraper is provided with flow grooves;

[0017] Explanation: The collision between the agitator teeth and the castable material can be used to crush the castable material; and the flow channel is set to improve the flowability of the castable material on the arc screen, thereby improving the screening efficiency.

[0018] The working principle of this utility model is as follows:

[0019] In use, the castable material to be screened is fed into the uppermost arc-shaped screen inside the shell through the feed inlet. The drive motor drives the linkage shaft to rotate, and the meshing of the incomplete gear and rack causes the arc-shaped screen to swing back and forth on the arc-shaped bracket. During the swinging of the arc-shaped screen, the castable material passes through each arc-shaped screen in sequence under the action of vibration. Finally, the castable material of different particle sizes is collected through the first collection hopper and the second collection hopper. During the screening of the castable material, the auxiliary motor drives the swing cam to rotate. The engagement between the swing cam and the push ring causes the rack frame to move back and forth on the outer wall of the shell, thereby causing the swing shaft to drive the scraper to swing back and forth above the corresponding arc-shaped screen, thus agitating the castable material.

[0020] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0021] First, the structure of this utility model is reasonably designed. It uses a drive motor to drive the arc screen to swing back and forth inside the shell, so that the castable material vibrates on the arc screen, which significantly improves the screening efficiency of the castable material and reduces the production cost.

[0022] Secondly, by setting up multiple arc-shaped screens with different apertures, this utility model can obtain multiple castables of different particle sizes in one screening, which not only improves the ease of use of the equipment, but also reduces the investment in equipment during the casting screening process.

[0023] Third, this utility model utilizes a reciprocating scraper to move the castable material on the arc-shaped screen, which not only improves the screening efficiency of the castable material, but also prevents the castable material from accumulating on the arc-shaped screen and causing blockage, thus improving the operational stability of the equipment.
