Description
Technical Field
[0001] The utility model relates to the field of concrete, in particular to a dust suction device for concrete additive packaging. Background Art
[0002] Introduction to concrete additives Concrete additives are a type of substance that can significantly improve the physical and chemical properties of concrete, increase the strength and durability of concrete, save cement, and reduce the size of structures, thereby achieving energy conservation and improving environmental and social benefits. Concrete additives are generally in powder form. During the preparation and production process, concrete additives need to be packaged. During packaging, floating dust is easily generated. A dust suction device is needed to adsorb and collect the generated floating dust during the packaging process. However, the existing dust suction device for concrete additive packaging has the following shortcomings when adsorbing the floating dust that is easily generated during packaging: the dust suction device is installed on the concrete additive packaging production line by locking, and the height and position of the dust suction device on the production line are relatively fixed, so that the dust suction inlet position is fixed. When the height between the dust suction inlet position and the dust is large, it is difficult to effectively adsorb and process the dust. After the dust suction work is completed, after the dust suction fan stops working, some of the dust at the dust suction inlet position is very easy to flow back to the production line, reducing the effect of comprehensive dust adsorption.

The dust suction fan 4 includes a connecting bottom plate 11, a supporting leg 12, a cylinder 13, a lifting frame 14, a telescopic plate 15, and a dust suction mechanism 16. The connecting bottom plate 11 is welded to the outer side of the lower end of the supporting leg 12, and the lower end of the cylinder 13 is welded to the lower end inside the supporting leg 12. The top of the cylinder 13 is welded to the bottom surface of the lifting frame 14, the inner side of the upper end of the lifting frame 14 is fixed to the outer end of the telescopic plate 15, and the inner end of the telescopic plate 15 is installed inside the upper end of the outer side of the dust suction mechanism 16 by clearance fit. The middle end of the top of the dust suction mechanism 16 is provided with a connecting tube 2 and is through-connected.
[0023] Among them, there are two connecting bottom plates 11, supporting legs 12, lifting frames 14 and telescopic plates 15, and they are installed symmetrically on the left and right. At the same time, three cylinders 13 are evenly distributed between each supporting leg 12 and the lifting frame 14. By synchronously starting the six cylinders 13 on both sides, the height between the supporting legs 12 and the lifting frame 14 can be smoothly adjusted, so that the installation height of the dust suction mechanism 16 on the concrete additive packaging production line can be adjusted arbitrarily, thereby improving the effect of the dust suction mechanism 16 on adsorbing dust on the production line.
[0024] Among them, the dust collection mechanism 16 includes a chassis 16a, a cloth curtain 16b, an inlet mechanism 16c, a conducting groove 16d, a torsion shaft 16e, and a guide piece 16f. The lower end of the chassis 16a is provided with a cloth curtain 16b, the inlet mechanism 16c is fixedly installed at the middle end of the chassis 16a, the conducting groove 16d runs through the center of the chassis 16a, and the lower end of the conducting groove 16d is connected with the upper end of the inlet mechanism 16c. The chassis 16a is connected with the connecting tube 2 through the conducting groove 16d, the outer end of the guide piece 16f is hinged to the inner part of the upper end of the chassis 16a through the torsion shaft 16e, and the guide piece 16f is located inside the conducting groove 16d, and the inner end of the telescopic plate 15 is installed inside the outer upper end of the chassis 16a with a clearance fit.
[0025] There are two cloth curtains 16b installed at the front and rear ends of the lower end of the chassis 16a. The two cloth curtains 16b can prevent dust from flying out when vacuuming the inside of the chassis 16a.
[0026] Among them, there are six torsion shafts 16e and guide plates 16f, and three are in a group, which are installed symmetrically on the left and right. At the same time, there is a certain height difference between the guide plates 16f on both sides, so that the guide plates 16f on both sides form an upward shrinking structure inside the conducting groove 16d, which is conducive to adsorbing dust upwards and reducing the occurrence of dust backflow downwards.
[0027] The inlet mechanism 16c includes an inlet slot plate c1 and a drop slot c2. The inlet slot plate c1 is fixedly installed at the lower end of the chassis 16a, and a drop slot c2 is provided at the lower end of the inlet slot plate c1. The upper end of the inlet slot plate c1 is connected to the conducting slot 16d.
[0028] Among them, the inlet trough plate c1 is a quadrangular pyramid structure with a wide lower end and a narrow upper end, and five drop grooves c2 are horizontally equidistantly arranged inside the lower end of the inlet trough plate c1. The five drop grooves c2 are horizontally connected to form a structure with a wide lower end and a narrow upper end at the lower end of the inlet trough plate c1, which is beneficial to guiding the dust on the production line upward, and part of the reflux dust can be collected by the drop grooves c2 to prevent the dust from falling on the production line again.
[0029] The specific usage and function of this embodiment are as follows:
[0030] According to the utility model, when the working host 1 is installed on the concrete additive packaging production line, the support legs 12 on both sides are moved and adjusted according to the width of the production line. During the adjustment, the lifting frame 14 and the dust suction mechanism 16 are telescopically connected through the telescopic plate 15. Then, the connecting bottom plate 11 is locked on the production line so that the dust suction mechanism 16 is in the middle position just above the production line to absorb the dust on the production line. During the absorption process, the six synchronous cylinders 13 on both sides are started to be telescopic according to the needs, and the height between the support legs 12 and the lifting frame 14 is smoothly adjusted, so that the installation height of the dust suction mechanism 16 on the concrete additive packaging production line can be arbitrarily adjusted, thereby improving the effect of the dust suction mechanism 16 on absorbing the dust on the production line. During adsorption, the dust is sucked into the conducting groove 16d from the inlet mechanism 16c by starting the dust suction fan 4 and the through conduction of the connecting tube 2 and the conducting tube 3. The guide pieces 16f on both sides and the torsion shaft 16e exert elastic torque to form an upwardly contracted structure inside the conducting groove 16d, which is conducive to adsorbing the dust upward and reducing the occurrence of dust backflow downward. At the same time, the two cloth curtains 16b can prevent the dust from flying out when the dust is sucked inside the chassis 16a. The inlet mechanism 16c is horizontally connected by five drop grooves c2 to form a structure with a wide bottom and a narrow top at the lower end of the inlet groove plate c1, which is conducive to guiding the dust on the production line upward, and part of the refluxed dust can be collected by the drop groove c2 to prevent the dust from falling on the production line again.
