Description

Technical Field

[0001] The utility model relates to the technical field of white carbon black production, in particular to a vacuum pumping device for white carbon black finished products. Background Art

[0002] Silica is a general term for white powdered, X-ray-dispersed amorphous silicic acid and silicate products, primarily precipitated silica, fumed silica, and ultrafine silica gel. It also includes powdered synthetic aluminum silicate and calcium silicate. Silica is a porous substance whose composition can be expressed as SiO₂·nH₂O, where nH₂O exists as surface hydroxyl groups. It is soluble in caustic soda and hydrofluoric acid but insoluble in water, solvents, and acids (except hydrofluoric acid). It is heat-resistant, non-flammable, tasteless, and odorless, and possesses excellent electrical insulation properties. During production, silica requires vacuum packaging.

[0003] However, the existing vacuum packaging machines have the following shortcomings when in use: vacuum packaging machines generally perform vacuuming, weighing, and packaging in their vacuum chambers. After the vacuum packaging is completed, the packaged silica needs to be manually lifted out of the vacuum chamber. Silica is usually packaged in large bags, which makes the overall weight large. It is very laborious to manually lift it out of the vacuum chamber. In this regard, we have proposed a vacuuming device for silica finished products to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a vacuum pumping device for silica finished products to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a vacuum pumping device for silica finished product, comprising:

[0006] The vacuum packaging machine body is provided with a vacuum chamber, a feed hopper is fixedly installed on the top of the vacuum packaging machine body, a box door is provided on the vacuum chamber, a packaging feeding mechanism is provided on the inner wall of the top side of the vacuum chamber, a weighing device is fixedly installed on the bottom side wall of the vacuum chamber, and an export mechanism is provided on the weighing device. The export mechanism includes two first conveying racks, and a plurality of equidistantly distributed first rollers are rotatably installed between the two first conveying racks. The front ends of the two first conveying racks are fixedly welded with rotating shafts, and second conveying racks are rotatably installed on the two rotating shafts, and a plurality of equidistantly distributed second rollers are rotatably installed on the second conveying rack.

[0007] Preferably, each of the two first conveying racks is provided with a pair of mounting blocks, and both pairs of mounting blocks are fixedly welded to the top wall of the weighing device.

[0008] Preferably, the mounting block is fixedly connected to the first conveying rack via set fastening bolts.

[0009] Preferably, a sliding rod is fixedly welded on the outer side wall of the first conveying frame near the outer end, a moving rod is slidably connected to the sliding rod, a tension spring is sleeved on the sliding rod, and the two ends of the tension spring are respectively fixedly connected to the first conveying frame and the moving rod, and a limiting sleeve is fixedly welded on the end of the moving rod away from the sliding rod.

[0010] Preferably, a limiting column is fixedly welded on the side wall of the second conveying rack, and the limiting sleeve is movably mounted on the limiting column.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model discloses that when the white carbon black is vacuum-packed in the vacuum chamber and needs to be taken out from the vacuum chamber, the moving rod can be pulled to make the moving rod slide outward on the slide rod, driving the limit sleeve to separate from the limit column, releasing the limit on the second conveyor frame, and then the second conveyor frame is flipped to the outer end and placed on the ground, so that the first conveyor frame and the second conveyor frame are in a slope shape. After that, the white carbon black packaging bag can be pulled to slide on the first roller to the second roller, and then slide to the ground, so that the white carbon black packaging bag can be easily taken out of the vacuum chamber. The operation is simple and convenient, making it easier and more labor-saving for workers to take out the packaged white carbon black packaging bags. BRIEF DESCRIPTION OF THE DRAWINGS
