Description

A dust collecting device for mixing station blockage production

Technical Field

The utility model relates to the technical field of mixing station production, in particular to a dust collecting device for mixing station blocking production.

Background Art

With the rapid development of industrialization, the building structure has become diversified. The load-bearing capacity of brick walls can no longer adapt to buildings with heavy loads. Today's large buildings usually use concrete frames as load-bearing structures. Concrete mixing stations are a type of equipment used to produce concrete. Due to their high production efficiency, stable quality, and easy operation, they are widely used in engineering construction. Concrete mixing stations use concrete mixers to mix cement, sand, stone and other materials evenly to form concrete, and use a conveying system to transport concrete to the construction site. There are some problems. During the concrete production process, a large amount of dust and other pollutant particles are often generated, which has a huge impact on environmental protection and workers' health. Concrete mixing stations often use pulse bag dust collectors to remove dust and collect pollutants. The dust-laden gas enters the machine body through the air inlet, passes through the dust collector bag, and flows out through the air outlet. The pollutant particles adhere to the dust collector bag. The pulse valve controls the compressed air to blow into the bag cage frame through the injection pipe to shake off the pollutants on the dust collector bag. The pollutant particles accumulate in the ash hopper by their own gravity and slowly enter the collection device. There are some problems. Due to the particularity of the mixing station, a large amount of dust will be generated during the concrete production process. When the traditional dust collector is working, the dust collection efficiency is low. Dust particles will accumulate in the ash hopper in large quantities. It is difficult for all of them to enter the collection device through the discharge port by their own gravity. If this continues for a long time, safety hazards such as blockage will occur. The pollutant particles in the collection device will also affect the equipment. For this reason, we propose a dust collection equipment for mixing station blockage production.

The working principle of the dust collecting equipment for material blocking production in a mixing station provided by the utility model is as follows: when performing dust removal work, the dust-containing gas enters the interior of the shell 1 through the air inlet pipe 4, the single-chip microcomputer 14 controls the operation of the negative pressure fan 13, and the upper end part of the partition 64 forms a negative pressure, and the dust-containing gas can pass through the dust bag 66 more efficiently and be discharged from the air outlet pipe 5. At the same time, more pollutant particles can be captured on the dust bag 66, and the dust removal work can be performed more efficiently. When enough pollutant particles are collected on the dust bag 66, the negative pressure fan 13 stops running, and the single-chip microcomputer 14 controls the electromagnetic pulse valve 62 to spray the compressed gas in the compressed gas tank 61 through the blowing head. The compressed gas passes through the venturi 67 and the flow rate becomes higher, and then enters the bag cage frame 65 to inflate the dust bag 66, so that the pollutant particles on the dust bag 66 fall into the ash hopper 9. At this time, the single-chip microcomputer 14 controls the operation of the motor 81, and the output shaft of the motor 81 drives the central shaft 83 to rotate, and the eccentric wheel 12 also rotates accordingly When the eccentric end of the eccentric wheel 12 contacts the bottom end of the cross frame 11, the cross frame 11 is forced to be lifted up, the spring 1 73 expands, and the push rod 74 moves up accordingly. The upper end of the push rod 74 contacts the side of the ash hopper 9, causing the ash hopper 9 to vibrate, and the pollutant particles accumulated inside the ash hopper 9 will also be shaken off to prevent clogging. Because a spring 2 76 is provided between the lower end of the outer ring 75 and the upper end of the sliding hole 2, and the spring 2 76 is sleeved on the lower end of the outer surface of the push rod 74, when the upper end of the push rod 74 contacts the ash hopper 9, Part of the force will be absorbed by the elastic potential energy of spring 2 76, which plays a buffering role and will not cause damage to the ash hopper 9. When the eccentric end of the eccentric wheel 12 leaves the bottom end of the cross frame 11, the cross frame 11 is not subjected to force, the spring 1 73 contracts, and the cross frame 11 returns to its original position, and so on. At the same time, the spiral feed sheet 82 also rotates with the rotation of the central shaft 83, and all the scattered pollutant particles will be transported to the collection device by the spiral feed sheet 82, completing the dust collection work and reducing the impact of dust on the equipment.

It is worth noting that the single chip microcomputer 14 disclosed in the above embodiment is an S7-200 single chip microcomputer, the electromagnetic pulse valve 62 is a DMF-Z-62S electromagnetic pulse valve, the motor 81 is a 6IK250RGU-CF motor, the negative pressure fan 13 is a FAC15-A negative pressure fan, and the single chip microcomputer 14 controls the operation of the electromagnetic pulse valve 62, the motor 81 and the negative pressure fan 13 using methods commonly used in the prior art.
