DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe in detail the specific embodiments of the present invention with reference to the drawings.

[0025] Refer to Figure 1 and Figure 2, the present utility model provides a dust removal mechanism for mixing raw materials for deoxidizer production, including a fixing plate 1, a feeding pipe cabin 2, a main dust suction pipe 3, a plurality of dust suction branch pipes 4, a filtering and collecting mechanism 5, and a centrifugal fan 6. The fixing plate 1 is fixedly installed at the opening top of the mixing container a. The feeding pipe cabin 2 is fixedly connected to the top of the fixing plate 1 and penetrates through the fixing plate 1 into the interior of the mixing container a. A plurality of dust suction branch pipes 4 are arranged at the bottom of the main dust suction pipe 3 and communicate with the main dust suction pipe 3. The bottom ends of a plurality of dust suction branch pipes 4 penetrate to the bottom of the fixing plate 1. One end of the main dust suction pipe 3 communicates with the interior of the feeding pipe cabin 2, and the other end of the main dust suction pipe 3 is docked with the filtering and collecting mechanism 5. The suction port of the centrifugal fan 6 communicates with the interior of the filtering and collecting mechanism 5. The filtering and collecting mechanism 5 is placed on the top of the fixing plate 1;

[0026] The air outlet of the centrifugal fan 6 is connected to a blowing end 8 through a connecting pipe 7, and the output end of the blowing end 8 penetrates into the interior of the feeding pipe cabin 2.

[0027] Refer to Figure 3 , the filtering and collecting mechanism 5 includes an outer cylinder cabin 51, an inner cylinder cabin 52, and a dust inlet connecting pipe 54. The dust inlet connecting pipe 54 penetrates through the outer cylinder cabin 51 and is connected to the interior of the inner cylinder cabin 52. The dust inlet connecting pipe 54 is docked with the main dust suction pipe 3. A plurality of mesh holes are provided on the side wall of the inner cylinder cabin 52, and a filter element 53 is fixedly sleeved on the side wall of the inner cylinder cabin 52 at the position of the mesh holes. A cover one 55 is fixedly installed on the top of the inner cylinder cabin 52, and a cover two 56 is fixedly installed on the top of the outer cylinder cabin 51. An exhaust through hole is provided on the top of the cover two 56. By operating the centrifugal fan 6, the air inside the outer cylinder cabin 51 is discharged through the exhaust through hole to form a negative pressure. The dust inside the main dust suction pipe 3 enters the interior of the inner cylinder cabin 52 through the dust inlet connecting pipe 54 under the influence of the negative pressure. The dust is blocked by the filter element 53, and the dust is collected and stored inside the inner cylinder cabin 52, while the gas passes through the filter element 53 and is discharged through the centrifugal fan 6.

[0028] Refer to Figure 4, the dust inlet connecting pipe 54 includes a first end pipe 541 and a second end pipe 542. The first end pipe 541 and the second end pipe 542 penetrate through the outer cylinder chamber 51 from both sides of the outer cylinder chamber 51 and are internally connected to the inner cylinder chamber 52. A fixed column 543 is fixedly connected to the inner wall of the second end pipe 542. One end of the fixed column 543 is provided with a polygonal column hole, and a moving column 544 is slidably sleeved in the polygonal column hole. One end of the moving column 544 extends to the inner wall of the first end pipe 541. A moving pipe 548 is fixedly connected to the side wall of the moving column 544 through a plurality of connecting plates 547. The moving pipe 548 is slidably sleeved on the inner wall of the first end pipe 541. The other end of the fixed column 543 is provided with a rotating hole communicating with the polygonal column hole, and a knob 545 is arranged in the rotating hole. One end of the knob 545 is fixedly connected to a threaded column 546. The moving column 544 is threadedly sleeved on the side wall of the threaded column 546. When in use, by rotating the knob 545 to drive the threaded column 546 to rotate, under the influence of the threaded structure, the moving column 544 can be displaced, so as to drive the moving pipe 548 to slide outwards from the inside of the first end pipe 541 until the moving pipe 548 is inserted into the dust suction main pipe 3, then the docking of the dust inlet connecting pipe 54 and the dust suction main pipe 3 is completed, and the operation is simple and fast.

[0029] Refer to Figure 4 , rubber sealing rings 549 are fixedly connected to both ends of the moving pipe 548. By arranging the two rubber sealing rings 549, the sealing performance between the moving pipe 548 and the first end pipe 541, and the sealing performance between the moving pipe 548 and the dust suction main pipe 3 can be improved.

[0030] Refer to Figure 2 , a concave embedding groove is arranged at the top of the fixing plate 1. The filtering and collecting mechanism 5 is embedded in the concave embedding groove, and the filtering and collecting mechanism 5 is adapted in the concave embedding groove. By arranging the concave embedding groove, on the one hand, it can prevent the filtering and collecting mechanism 5 from accidentally displacing and damaging the dust suction main pipe 3, improving the structural stability. On the other hand, it can position the placement position of the filtering and collecting mechanism 5, facilitating the connection with the dust suction main pipe 3.

[0031] Refer to Figure 5 , the blowing end head 8 includes an annular air duct 81. The annular air duct 81 is sleeved on the side wall of the feeding pipe chamber 2. A plurality of air outlet nozzles 82 distributed in a ring shape are arranged on the inner ring wall of the annular air duct 81. One end of the plurality of air outlet nozzles 82 is communicated with the inside of the annular air duct 81, and the other end is communicated with the inside of the feeding pipe chamber 2. The connecting pipe 7 is communicated with the inside of the annular air duct 81. When the gas is blown into the inside of the annular air duct 81 through the connecting pipe 7, it can be shunted and blown out into the feeding pipe chamber 2 through the plurality of air outlet nozzles 82. Through the annular distribution position of the plurality of air outlet nozzles 82, the effect of forming an air wall inside the feeding pipe chamber 2 can be achieved. Through the inclined effect of the air outlet nozzles 82, the air outlet nozzles 82 can blow obliquely downwards, so as to achieve a downward guiding effect when the feeding pipe chamber 2 is feeding.

[0032] Refer to Figure 6, the dust suction branch pipe 4 includes a main branch pipe 41, and a horn-shaped end 42 is fixedly connected to the bottom end of the main branch pipe 41. Due to the shape characteristics of the horn-shaped end 42, it is more conducive to the floating dust in the mixing container a to enter.

[0033] The working principle of the present utility model: By operating the centrifugal fan 6, suction force is generated in the dust suction main pipe 3 and several dust suction branch pipes 4. During use, feeding is carried out into the mixing container a through the feeding pipe cabin 2. Under the action of the centrifugal fan 6, the dust generated during the feeding process can be absorbed. Through the connection effect of the dust suction main pipe 3 and the dust suction branch pipes 4, when the raw materials in the mixing container a are mixed, the floating dust generated can be absorbed into the dust suction main pipe 3 through several dust suction branch pipes 4. In addition, the air blown out during the operation of the centrifugal fan 6 is blown into the feeding pipe cabin 2 through the blowing end 8 under the connection effect of the connecting pipe 7, forming an air wall inside the feeding pipe cabin 2 to prevent some of the floating dust that has not been absorbed by the dust suction main pipe 3 from passing through, thereby avoiding the generation of floating dust in the process of mixing the deoxidizer raw materials, which affects the working environment and physical and mental health;

[0034] The floating dust absorbed by the dust suction main pipe 3 flows into the filter collection mechanism 5 and is uniformly collected and stored to avoid waste of raw materials.

[0035] The above shows and describes the basic principle, main features and advantages of the present utility model. The present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
