Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, in particular to a device for preventing dust from emitting when adding materials to a mixing box. Background Art

[0002] Mixing equipment is a device used to mix and stir different substances. Common mixing equipment includes mixing barrels, blenders, mixing tanks, etc. Mixing equipment is widely used in the fields of machinery, metallurgy, etc. In mixing equipment, a motor is usually used to drive the agitator for mixing, so as to achieve uniform mixing of materials. For example: rolling oil is used for cooling, lubrication, and cleaning in the rolling of aluminum sheets, strips, and foils. After use, the rolling oil carries a large amount of impurities back to the dirty oil tank and needs to be filtered before use. Plate filters are generally used for filtering. When diatomaceous earth, activated clay, and other filter aids are added to the mixing box, they are mixed evenly with the rolling oil in the mixing box and then enter the plate filter through the oil pipeline to establish a filter layer constructed by diatomaceous earth, activated clay, and filter paper.

[0003] Since filter aids such as diatomaceous earth and kaolin are all powder particles, the materials will float on the surface due to height difference and interfacial force when adding materials. At the same time, a large amount of dust dispersion will be generated during the adding process, causing harm to the operators.

[0004] However, when adding materials to the current filtration equipment, since filter aids such as diatomaceous earth and kaolin are all powdered particles, the materials will float on the surface due to the height difference and interfacial force. When the materials are put into the mixing box, dust will easily come out from the feed port when they are added to the inside of the box. A large amount of dust will be dispersed during the feeding process, which will cause harm to the operators and seriously affect the environmental protection of the mixing equipment.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] like Figures 1 to 5As shown, a device for preventing dust from emitting when adding materials to a mixing box comprises a box body 2, a cover body 4 and a mixing device, wherein a pressure ring 22 is integrally extended from the upper end of the box body 2, and a cover body 4 is detachably provided on the pressure ring 22. The cover body 4 and the pressure ring 22 can be fixedly connected by bolts or the like. The mixing device is arranged on the cover body 4, and a mixing claw assembly 91 of the mixing device extends into the interior of the box body 2. It also comprises an ash baffle 8, which is obliquely arranged inside the box body 2, and the outer wall of the ash baffle 8 is arranged close to the inner wall of the box body 2, and one side of the ash baffle 8 is provided with an opening 81 for dropping materials; the position of the opening 81 is located at the lower end of the box body 2, and a feed port 41 is provided on the cover body 4, and the feed port 41 is butted with the upper end of the ash baffle 8. That is, the ash baffle 8 is obliquely arranged inside the box body 2, and one side of the opening 81 of the ash baffle 8 is arranged at a low position. In this way, when the material falls through the feed port 41, it will fall onto the ash baffle plate 8 and be buffered by the ash baffle plate 8, and then it will slide downward on the ash baffle plate 8 and fall into the box body 2 through the opening 81. A siphon 21 is provided on the cover body 4, and the siphon 21 extends into the box body 2. After the material is stirred, it is extracted through the siphon 21.

[0027] The ash baffle 8 is arranged in a sloped manner, and its bottom end can be partially immersed in the rolling oil, which can reduce the dust generated by the height difference of the material and accelerate the mixing of the material and the rolling oil; a relatively closed space is formed by the ash baffle 8 and the box body 2, and the dust circulates in the box body 2 to reduce overflow.

[0028] Such a design is equivalent to the ash baffle 8 serving as an intermediate buffer device, which reduces the impact force of materials falling from a height through the ash baffle 8, thereby reducing the feeding height, making it less likely to generate dust and emit ash; and, after the material falls from the opening 81 of the ash baffle 8 into the interior of the box body 2, there is a certain angle between the inclined ash baffle 8 and the box body 2, and the narrow space can block most of the ash emission, making it difficult for dust to emerge upward through the opening 81. Even if a small amount of material emerges from the opening 81, it will be blocked by the cover body 4 and fall onto the ash baffle 8 again, thereby greatly reducing the ash emission from the feeding port 41.

[0029] like Figure 3-5 As shown, the opening 81 is set to be an elliptical shape, and the opening 81 extends to the inner wall of the box body 2. With this design, the material falling on the ash baffle 8 can fall completely from the opening 81 to the inside of the box body 2, and the material will not accumulate on the ash baffle 8. Of course, in addition to being set to an elliptical shape, the opening 81 can also be set to other shapes such as a circle, a long strip, etc.

[0030] like Figure 5 As shown, the center of the box body 2 is set inside the opening 81. Such a design ensures that the stirring shaft 9 of the stirring device can penetrate into the box body 2 through the opening 81 to achieve the stirring operation.

[0031] like Figure 1-5As shown, a plurality of connecting screws 82 are arranged on the circumference of the ash baffle 8, and a plurality of locking nuts 83 are arranged on the connecting screws 82. The connecting screws 82 are passed through the cover body 4 and fixed by the locking nuts 83. Such a design can achieve the detachable connection of the ash baffle 8. The ash baffle 8 is connected to the cover body 4. When the cover body 4 is removed, the ash baffle 8 can also be removed, which is convenient for disassembly and assembly. At the same time, when the box body 2 is stirred for a long time, a large amount of material may adhere to the inner wall of the ash baffle 8. Because the ash baffle 8 needs to be flushed, the ash baffle 8 is connected to the cover body 4, which is convenient for disassembly and cleaning. Secondly, the height of the ash baffle 8 can be adjusted, that is, the falling height of the material can be adjusted, so that the height of the ash baffle 8 can be adaptively adjusted according to the feed flow rate of the material. Of course, the ash baffle 8 can also be directly welded to the inner wall of the box body 2, so that the height of the ash baffle 8 cannot be adjusted and it is not convenient for disassembly and assembly.

[0032] In the utility model, the stirring device includes a driving motor 5, a primary reduction box 51, and a secondary reduction box 7. The side wall of the box body 2 is provided with a fixing seat 3, and the driving motor 5 is arranged on the fixing seat 3. The primary reduction box 51 is arranged at the upper end of the cover body 4, and the secondary reduction box 7 is arranged on the inner wall of the cover body 4. A plurality of mutually meshing gears are arranged in the secondary reduction box 7. In the utility model, three gears are arranged, namely, gear 1 71, gear 2 72 and gear 3 73. Gear 1 71 is meshed with gear 2 72, and gear 2 72 is meshed with gear 3 73. The driving motor 5 is connected to the input shaft of the primary reduction box 51 for transmission, the output shaft of the primary reduction box 51 is connected to gear 1 71 for transmission, and gear 3 73 is connected to the stirring shaft 9 for transmission. Gear 1 71, gear 2 72 and gear 3 73 are all rotatably arranged inside the secondary reduction box 7, and the stirring shaft 9 is arranged on the axis of the box body 2, and a plurality of stirring claw assemblies 91 are connected to the stirring shaft 9. The structural design of the stirring equipment is optimized by means of the primary reduction gearbox 51 and the secondary reduction gearbox 7. The secondary reduction gearbox 7 is arranged inside the cover body 4. In order to avoid the problem of insufficient space caused by the secondary reduction gearbox 7 being arranged outside the box body 2 and interfering with the feed port 41, the secondary reduction gearbox 7 is optimized to be arranged in the space inside the box body 2, so that the feed port 41 and the secondary reduction gearbox 7 can be avoided.

[0033] Further, the secondary reduction box 7 is arranged between the dust shield 8 and the cover 4. Due to the existence of the dust shield 8, there is extra space between the dust shield 8 and the cover 4, which can be used to accommodate the secondary reduction box 7, thereby reasonably utilizing the space of the box 2.

[0034] In the utility model, the angle between the dust baffle plate 8 and the cover body 4 can be 30-45°. At this angle, the falling speed of the material is relatively slow, which can avoid the dust problem. At the same time, at this angle, the space between the dust baffle plate 8 and the cover body 4 is sufficient to accommodate the secondary reduction box 7.

[0035] Furthermore, the inner wall of the feed port 41 is provided with a filter assembly 6. Through the filter assembly 6, the material can be filtered when it is discharged, and unqualified materials can be removed. At the same time, when the material falls into the box body 2, the existence of the filter assembly 6, combined with the dust baffle 8, can suppress dust to a certain extent.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
