Description

Technical Field

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

[0002] Refractory waste screening and dust removal equipment is a device specifically designed to treat waste generated during the production of refractory materials. It is widely used in many industries such as mining, building materials, metallurgy, chemical industry, power, coal, and grain processing. It aims to separate different particle size components in the waste and remove dust to reduce the impact on the environment and recycle reusable materials.

[0003] When using the refractory waste screening and dust removal device, the refractory waste to be screened is usually poured into the screening cylinder. Then, the drive equipment drives the screening cylinder to rotate. The refractory waste is screened by the screening cylinder and falls into the hopper through the screening holes. Finally, it is discharged through the hopper. During the screening process, the dust discharge valve is opened and the external air extraction equipment extracts the dust generated during the screening process through the dust discharge pipe.

[0004] Existing refractory waste screening and dust removal devices, due to the fixed position of the screening cylinder, result in some screen areas not being fully utilized, reducing screening efficiency. Refractory waste tends to accumulate in certain areas of the screening cylinder, causing blockage of the screening holes and affecting screening effect and production efficiency. Therefore, we propose a refractory waste screening and dust removal device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a refractory waste screening and dust removal device, including a mounting frame 1, a feeding hopper 16 is respectively provided at the lower end of the mounting frame 1, a protective cover 3 is provided at the upper end of the mounting frame 1, a dust discharge pipe 8 is respectively provided in the dust discharge port opened on the upper side of the outer arc surface of the protective cover 3, a dust discharge valve is connected in series on the upper side of the dust discharge pipe 8, a screening cylinder 4 is provided inside the protective cover 3, a screening hole 15 is respectively provided inside the screening cylinder 4, a mounting cylinder 5 is provided at the left end of the screening cylinder 4, and a driving mechanism 9 is also included.

[0023] Drive mechanism 9 includes a mounting cover 91, a rotating cylinder 93, and a transmission seat 94. The mounting cover 91 is located in the middle of the left end of the protective cover 3. The rotating cylinder 93 is located on the rear side inside the mounting cover 91. The transmission seat 94 is located in the middle of the outer arc surface of the rotating cylinder 93.

The drive mechanism 9 also includes an output rod 92, a connecting rod 95, a bevel gear 96, a limiting groove 97, and a limiting rod 98. The output rod 92 is rotatably connected to the rear side of the left wall of the mounting cover 91. The rotating cylinder 93 is rotatably connected to the middle of the outer arc surface of the output rod 92. The connecting rod 95 is located on the front side of the outer arc surface of the rotating cylinder 93. The front side of the outer arc surface of the connecting rod 95 and the output rod 96 are connected. 2. A bevel gear 96 is provided on the right side of the outer arc surface. The two bevel gears 96 are meshed and connected. A limit rod 98 is provided on the lower side of the front end of the bevel gear 96. A limit groove 97 is provided on the right side of the inner arc surface of the mounting cylinder 5. The front end of the limit rod 98 is located inside the limit groove 97. The limit rod 98 drives the mounting cylinder 5 to perform a transverse reciprocating motion. Then, the mounting cylinder 5 drives the screening cylinder 4 to perform a transverse reciprocating motion. This can increase the contact frequency between the refractory waste and the screening cylinder 4, thereby improving the screening efficiency, distributing the refractory waste more evenly, avoiding local overload, and the shaking action also helps to break the accumulation and blockage of refractory waste in the screening cylinder 4, maintaining the permeability of the screening holes 15.

[0024] It also includes a control switch 2, which is located at the right end of the mounting bracket 1. The input terminal of the control switch 2 is electrically connected to an external power supply and can control the electrical components inside the equipment.

[0025] Among them: a crossbar 10 is rotatably connected to the front side of the left wall of the mounting cover 91. Gears 11 are provided in the middle of the outer arc surface of the crossbar 10 and on the left side of the outer arc surface of the rotating cylinder 93. The two gears 11 are meshed and connected. The crossbar 10 drives the rotating cylinder 93 to rotate through the meshing connection between the gears 11.

[0026] Wherein: a pulley 12 is provided on the left side of the outer arc surface of the output rod 92, and a drive pulley 13 is provided on the left side of the outer arc surface of the crossbar 10. The pulley 12 and the drive pulley 13 are connected by a conveyor belt. The output rod 92 drives the crossbar 10 to rotate through the transmission connection between the drive pulley 11 and the pulley 12.

[0027] Wherein: a motor 14 is provided on the rear side of the left end of the mounting cover 91. The right end of the output shaft of the motor 14 is fixedly connected to the left end of the output rod 92. The input end of the motor 14 is electrically connected to the output end of the control switch 2. By controlling the control switch 2, the motor 14 starts to run, and the output shaft of the motor 14 drives the output rod 92 to rotate.

[0028] Among them: the upper right side of the protective cover 3 is hinged with a protective door 6, and the right end of the screening cylinder 4 is hinged with a sealing door 7. Before use, the dust discharge pipe 8 is connected to the external pipe, and then the protective door 6 and the sealing door 7 are opened to pour the refractory waste to be screened into the interior of the screening cylinder 4.

[0029] The working principle of the refractory waste screening and dust removal device provided by this utility model is as follows: Before use, connect the dust discharge pipe 8 to the external pipe, and then open the protective door 6 and the sealing door 7 to pour the refractory waste to be screened into the screening cylinder 4. After the refractory waste is added, close the protective door 6 and the sealing door 7 again. At this time, the motor 14 starts to run through the control switch 2. The output shaft of the motor 14 drives the output rod 92 to rotate. The output rod 92 drives the transmission between the drive pulley 11 and the pulley 12. The crossbar 10 rotates, and the crossbar 10 rotates the rotating cylinder 93 through the meshing connection between the gears 11. This rotating cylinder 93 then rotates the mounting cylinder 5 through the transmission seat 94. The mounting cylinder 5 rotates the screening cylinder 4. During the rotation of the screening cylinder 4, the refractory waste is screened by the screening cylinder 4 and falls through the screening holes 15 into the hopper 16, where it is finally discharged. The output rod 92 rotates in the opposite direction to the crossbar 10. During the rotation of the output rod 92, the output rod 92 rotates through the cone... The meshing connection between gears 96 drives the front bevel gear 96 to rotate around the connecting rod 95. Since the rotating cylinder 93 does not change position during this time, and there is an eccentric gap between the connecting rod 95 and the limiting rod 98, the limiting rod 98 revolves around the connecting rod 95 as the front bevel gear 96 rotates. During this revolution, the limiting rod 98 slides within the adjusting groove 97 and rotates relative to it, resulting in a positional change. When the limiting rod 98 is within the adjusting groove 97, the front bevel gear 96 rotates clockwise from left to right. When in motion, the limiting rod 98 drives the mounting cylinder 5 to move to the right through the adjusting groove 97. When the bevel gear 96 on the front side of the limiting rod 98 rotates clockwise from right to left, the limiting rod 98 drives the mounting cylinder 5 to move to the left through the adjusting groove 97, so that the limiting rod 98 can drive the mounting cylinder 5 to perform lateral reciprocating motion through the adjusting groove 97. The mounting cylinder 5 then drives the screening cylinder 4 to perform lateral reciprocating motion. During the screening process, the dust discharge valve is opened, and the external air extraction equipment can extract the dust generated during the screening process through the dust discharge pipe 8.

[0030] It is worth noting that the motor 14 disclosed in the above embodiments can be 5IK200A-AF, and the control switch 2 is provided with a control button corresponding to the motor 14 for controlling its switching.
