Description

Technical Field

[0001] The invention relates to a material transport device, in particular to a peristaltic material displacement aerator. Background Art

[0002] The air lock, also known as the air lock fan, is a commonly used transmission machine. Before and after the main equipment of various environmental protection, metallurgy, chemical industry, grain, food and other industrial departments, the material shape change is inseparable from the feeding and unloading material devices. In order to ensure the chemical reaction of the materials in the generator is sufficient, the generator feed port and discharge port need to be effectively sealed for the continuous operation of the generator.

[0003] The existing solid material generator feed and discharge ports generally use air shutoffs or air locks, which functionally separate the material and the gas carried by the material. However, the common air shutoffs and air locks are all cylindrical casings. The center of the casing cylinder is designed with a central axis and an air lock. The central axis is designed with multiple blades perpendicular to the central axis. The central axis drives the blades to rotate under the action of the driving force. The material intermittently enters the adjacent blade grooves from top to bottom to form a closed-door seal. On the basis of affirming the closed-door closure, two fatal defects are exposed: First, the newly put in material causes jamming at the outer edge of the blade and the edge of the casing opening, which increases the power consumption of the driving force by several times. Second, there are always gaps in the uniform distribution of the blades around the circumference. When the blades implement the closing action, the gas carried by the material takes the opportunity to enter, and the ideal sealing effect cannot be achieved. Summary of the invention

[0004] The object of the present invention is to provide a peristaltic material displacement aerator to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] As a further solution of the present invention: a support plate is fixedly installed at the bottom of the feed plate, and the support plate is an L-shaped plate extending toward one side of the roller frame.

DETAILED DESCRIPTION

[0016] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0017] See also Figures 1-2In this embodiment, a peristaltic material displacement aerator comprises a base plate 1, a drum disc 6, a roller 12 and a material bag 10, wherein a main bracket 4, a sub-bracket 5 and a vertical plate 2 are fixedly mounted on the base plate 1, a roller frame is rotatably mounted on the vertical plate 2, a plurality of rollers 12 are rotatably mounted on the roller frame in a circular distribution, a feed plate 9 whose height is higher than the roller frame is fixedly mounted on the main bracket 4 and the sub-bracket 5, the material bag 10 is respectively attached to the roller 12 in a curved state, one end of the material bag 10 is connected to the feed plate 9, and the other end of the material bag 10 is connected to the discharge plate 3, a support plate 8 is fixedly mounted on the bottom of the feed plate 9, the support plate 8 is an L-shaped plate body extending toward one side of the roller frame, an inclined plate 7 is installed between the horizontal plate and the vertical plate of the support plate 8, and the front end of the material bag 10 is overlapped on the support plate 8 and the inclined plate 7. The peristaltic material displacement aeration machine realizes the material-gas separation of the solid fluid by coordinating the material discharge between the material bag 10 and the roller frame and the roller 12 .

[0018] Combination Figure 3 Specifically, the roller frame includes two wheel drum discs 6 and a wheel drum 11 coaxially fixedly installed between the two wheel drum discs 6. In order to facilitate the installation and disassembly of the roller 12, a roller shaft installation opening 13 is opened on the wheel drum disc 6 for radial insertion of the connecting shaft of the roller 12.

[0019] The material bag 10 of the peristaltic material displacement aerator is distributed into four areas by the rollers 12, namely, the material storage area A located between the feed plate 9 and the first roller 12a adjacent to it; the material lifting area B located between the first roller 12a and the second roller 12b at the highest point and adjacent to the material storage area A; the material discharge area C located between the second roller 12b and the third roller 12c adjacent to it and adjacent to the material lifting area B; and the material discharge area D located between the third roller 12c and the fourth roller 12d adjacent to it and adjacent to the material discharge area C.

[0020] Among them, in the material storage area A, the material falls from the feed plate 9 into the material bag 10 and is pressed on the inclined plate 7 and the support plate 8. After the material is put into the material bag 10, it is accumulated at an angle of about 40° in the material bag 10 due to its weight. The material in the material bag 10 at the end of the material storage area A squeezes the material bag 10 and falls between the first roller 12a and the support plate 8, waiting to be rolled and lifted by the roller frame.

[0021] As the roller frame rotates forward and under the friction of the material bag 10, the roller 12 reverses and pushes the material in the material bag 10 to increase its mass and volume at the same time, so that the material enters the material lifting area B, and pushes the material in the material bag 10 to increase its mass and volume at the same time. When the material is pushed to the end of the material lifting area B, that is, the inflection point of the second roller 12b, the top of the material bag 10 collapses and deflates, and the material is freely compacted, and the air is exhausted in the opposite direction of the material flow, so that the air in the material is discharged toward the feed plate 9.

[0022] After the material in the bag 10 is rolled and lifted to the turning point of the second roller 12b, as the roller frame continues to rotate, the material in the bag 10 hangs down between the second roller 12b and the third roller 12c, that is, enters the material drop area C. The bag 10 in the material drop area C is lifted up by the rollers 12 that slide freely at both ends, namely the second roller 12b and the third roller 12c, due to the weight of the material in the bag, and the bag 10 lifted up by the rollers 12 at both ends is in a sealed state.

[0023] As the roller frame rotates, the material in the bag 10 passes over the third roller 12c and falls on the top of the fourth roller 12d for instant accumulation. At this time, the material enters the unloading area D, then passes over the fourth roller 12d and squeezes the bag 10 and is discharged from the discharge plate 3.

[0024] The peristaltic material displacement aeration machine is suitable for the front and rear assembly of the main equipment of the environmental protection, metallurgy, chemical industry, grain, food and other industrial departments, and is suitable for the flow and aeration of various irregular materials. It has low production cost, power consumption is less than 20% of the fan or air lock equipped with the running equipment, and it runs smoothly continuously. According to user requirements, the peristaltic material displacement aeration machine can be designed to be equipped with gasifiers, boilers, dryers and other equipment in different specifications to control the material carrying gas in the fluid displacement of solid materials.
