Technical Field

[0001] The utility model relates to the technical field of emulsified asphalt storage, in particular to a storage device for emulsified asphalt production with good sealing performance. Background Art

[0002] Emulsified asphalt is an oil-in-water (O / W) asphalt emulsion made by dispersing viscous asphalt into droplets through heat and mechanical action in water containing an emulsifier and stabilizer. This emulsion can be used at room temperature or with cold, damp stone. It exhibits strong adhesion, aging resistance, and water resistance. However, specialized storage facilities are required to ensure its quality and stability.

[0003] For example, the Chinese authorized patent "An Emulsified Asphalt Storage Device" with announcement number CN215624224U includes a storage tank; a stirring device is provided inside the storage tank, and an asphalt inlet and an asphalt outlet are provided on the top of the storage tank; a double-layer tube is provided around the outer wall of the storage tank, and a vent hole connected to the outer layer of the double-layer tube is provided near the upper end of the storage tank, and the inner layer of the double-layer tube is connected to the heat transfer oil pipe; an insulation layer covering the double-layer tube is provided on the outer wall of the storage tank, and a temperature sensor and a liquid level sensor are provided on the outer wall of the storage tank; and a through hole is provided on the fan blade of the stirring device.

[0004] Although the above-mentioned existing technology can realize the storage of emulsified asphalt, the overall sealing performance is poor, which is not conducive to the long-term preservation of emulsified asphalt. Although there are completely sealed storage devices for emulsified asphalt on the market, due to changes in the temperature environment, the moisture in the device is prone to evaporation and swelling, causing certain hidden dangers. Therefore, it does not meet the existing needs. In this regard, we propose a storage device for emulsified asphalt production with good sealing performance. Utility Model Content

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a storage device for emulsified asphalt production with good sealing performance, comprising a cylinder, a top cover being provided above the cylinder for locking engagement, and further comprising:

[0007] A pressure ring is provided above the upper cover, the lower end of the inner wall of the pressure ring is wrapped around the outer edge of the upper end of the upper cover, the upper end of the pressure ring is provided with a cross-shaped fixing frame, an adjusting bolt is installed at the center position of the fixing frame, and the adjusting bolt is threadedly connected to the fixing frame, a pressure plate is installed at the lower end of the adjusting bolt, the bottom surface of the pressure plate is in contact with the top end of the upper cover, and the pressure plate and the adjusting bolt are connected through a bearing;

[0008] An exhaust mechanism is provided at the upper end of one side of the cylinder body. An exhaust hole communicating with the inside of the cylinder body is provided inside the exhaust mechanism. A sealing groove is provided on one side inside the exhaust hole, and a movable sealing plug is installed on one side of the sealing groove.

[0009] Preferably, a rotating seat is provided on one side of the opening of the cylinder body, and one side of the pressing ring is connected to the rotating seat through a rotating shaft. A fixed ear is provided on the other side of the opening of the cylinder body, and a mounting ear is provided on the other side of the pressing ring. The mounting ear and the fixed ear are connected by a locking bolt.

[0010] Preferably, a fixed seat is fixedly provided at the middle position of the exhaust hole. A movable rod is fixedly provided on one side of the sealing plug. The movable rod passes through the fixed seat and is slidably connected to the fixed seat. Limiting sliders for sliding limit with the fixed seat are provided on both sides of the end of the movable rod located inside the fixed seat. Springs are installed between the limiting sliders and the sliding grooves of the fixed seat. A through hole communicating with the exhaust hole is provided on the outer ring inside the fixed seat.

[0011] Preferably, a sealing cap is installed outside the exhaust mechanism, and the sealing cap is threadedly connected to the exhaust mechanism. A hole is provided at the central position of the sealing cap, and the movable rod is slidably matched with the hole of the sealing cap.

[0012] Preferably, a first sealing ring is provided on the outer ring at the bottom of the upper cover. There are at least three first sealing rings, and the first sealing rings are in snap-fit with the clamping grooves on the upper end surface of the cylinder body.

[0013] Preferably, a sealing ring is provided at the bottom of the upper cover. A plurality of second sealing rings are provided on the outer wall of the sealing ring, and the second sealing rings are in close contact with the inner wall of the cylinder body after being extruded.

[0014] Preferably, a sealing retaining ring is provided at the end of the movable rod located outside the fixed seat.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By providing a pressing ring, the pressing ring is separated from the upper opening of the cylinder body during the injection process of emulsified asphalt, avoiding obstruction to the injection of emulsified asphalt. After the staff seals the upper cover on the upper end of the cylinder body, the pressing ring is flipped so that its inner wall wraps around the outer edge of the upper end of the upper cover. At the same time, the locking bolt is screwed into the fixed ear to ensure the fixing effect of the pressing ring and the cylinder body. Subsequently, by rotating the adjusting bolt, the rotational motion is converted into linear motion under the thread friction between the adjusting bolt and the fixed frame, thereby driving the lower pressing plate to move upward to the top of the upper cover until it forms a press fit, so as to ensure the tight fit between the upper cover and the cylinder body, effectively ensuring the storage sealing performance of emulsified asphalt.

[0017] 2. The utility model is provided with an exhaust mechanism. Affected by the storage environment, if the internal moisture evaporates due to the increase in temperature, resulting in flatulence, the air pressure inside the cylinder will increase, squeezing the sealing plug, causing the sealing plug to drive the movable rod to move outward, forming an open space between the sealing groove and the sealing plug. At the same time, the movable rod will extend to the outside of the sealing cap. When the staff finds that the movable rod protrudes outside the sealing cap, the sealing cap can be rotated and separated from the exhaust mechanism under the thread fit, opening the exhaust hole. At this time, the expanded gas is discharged under the pressure difference. After the pressure difference decreases, the sealing plug blocks the sealing groove again under the reset action of the spring to prevent the entry of external air. Then, the sealing cap is tightened to further improve the overall sealing performance and avoid internal flatulence while ensuring the sealing performance.

[0018] 3. The utility model provides a basic sealing guarantee by arranging a plurality of first sealing rings on the outer ring of the bottom surface of the upper cover, and the first sealing rings are engaged with the annular grooves on the upper edge of the cylinder body. At the same time, a sealing ring is arranged on the bottom surface of the upper cover, and a plurality of second sealing rings are arranged on the outer wall of the sealing ring. During the closing process of the upper cover and the cylinder body, the second sealing rings are squeezed, so that they are closely attached to the inner wall of the cylinder body, further improving the sealing performance between the upper cover and the cylinder body and providing good conditions for the long-term storage of emulsified asphalt.
