Description

Technical Field

[0001] The utility model relates to the technical field of plastic runway construction, in particular to a drying machine for plastic runway construction. Background Art

[0002] The plastic track, also known as the track and field sports track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. It has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. After the construction of the plastic track is completed, in order to put it into use as soon as possible, the moisture on its surface needs to be dried by a dryer.

[0003] The current dryers for plastic track construction usually use hot air to blow directly onto the plastic track to dry out moisture, but the hot air is easily dissipated into the atmosphere, resulting in serious heat waste, high energy consumption, and poor drying effect. For this reason, we propose a dryer for plastic track construction. Utility Model Content

[0004] The utility model aims to provide a dryer for plastic runway construction, which has the advantages of being able to recycle drying hot air in the process of drying the moisture on the plastic runway surface, thereby reducing heat waste and energy consumption and improving the drying effect. It solves the problem that the current dryer for plastic runway construction usually uses hot air to blow directly onto the plastic runway to dry the moisture, but the hot air is easily dissipated in the atmosphere, resulting in serious heat waste, high energy consumption and poor drying effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dryer for plastic track construction, comprising a movable cover, a water collecting tank is fixedly installed on the upper surface of the movable cover, a condensing box is fixedly installed on the upper surface of the water collecting box, an air duct is fixedly connected to one side of the upper surface of the condensing box, and the end of the air duct is fixedly connected to one side of the outer surface of the movable cover, an air duct fan is fixedly installed inside the air duct, an electric heating network is fixedly installed on the side of the movable cover close to the air duct, a connecting air duct is fixedly connected to the side of the upper surface of the movable cover facing away from the air duct, and the end of the connecting air duct is fixedly connected to the side of the upper surface of the condensing box facing away from the air duct, a connecting pipe is fixedly connected to the lower surface of the condensing box, and the end of the connecting pipe is fixedly connected to the upper surface of the water collecting box.

[0006] Preferably, movable wheels are rotatably mounted at both sides of the front surface and the rear surface of the movable cover.

[0007] Preferably, the second heat sink and the first heat sink are equidistantly fixedly installed on the inner wall of the condensing box near the front surface and the rear surface, and the first heat sink and the second heat sink are spaced apart from each other, and the first heat sink and the second heat sink run through the condensing box.

[0008] Preferably, a fan frame is fixedly mounted on the upper surface of the condensing box at a position above the first heat sink and the second heat sink, and a ventilation fan is fixedly mounted inside the fan frame.

[0009] Preferably, a protective net is fixedly installed inside the fan frame at a position above the ventilation fan.

[0010] Preferably, a sealing strip is provided on the lower surface of the movable cover, a clamping protrusion is provided on the upper surface of the sealing strip, a clamping groove is provided on the lower surface of the movable cover, and the clamping protrusion is located inside the clamping groove.

[0011] Preferably, a handle is fixedly mounted on one side of the outer surface of the condensation box close to the air duct, and a start-stop switch is fixedly mounted on the upper surface of the handle.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model achieves the goal of recycling the drying hot air in the process of drying the moisture on the plastic runway pavement by arranging a movable hood, an electric heating network, an induced draft duct, an induced draft fan, a condensing box, a water collecting box and a connecting air duct. In the process of drying the moisture on the plastic runway pavement, the utility model can achieve the goal of recycling the drying hot air in the process of drying the moisture on the plastic runway pavement, reducing heat waste and energy consumption, and also improving the drying effect. In the process of the movable hood moving, the electric heating network is energized for heating, and the induced draft fan conveys air to the inside of the movable hood. The air is heated after passing through the electric heating network from top to bottom, and the hot air is blown to the plastic runway pavement and flows toward the connecting air duct. The hot air dries the moisture on the plastic runway pavement, and after the moisture evaporates, it forms humid hot air together with the hot air. The humid hot air enters the condensing box through the connecting air duct, and the water vapor in the humid hot air is cooled and liquefied inside the condensing box and discharged into the water collecting box. The hot air after the water vapor is removed is heated again by the electric heating network under the guidance of the induced draft fan and then blown to the plastic runway pavement. The hot air is recycled, reducing heat waste and energy consumption, and also improving the drying effect.

[0014] 2. The utility model increases the flow of humid hot air inside the condensation box by arranging the first heat sink and the second heat sink, which is beneficial to the condensation and liquefaction of water vapor in the humid hot air. The first heat sink and the second heat sink distributed at intervals inside the condensation box make the humid hot air flow in a wave shape inside the condensation box, extending the flow of the humid hot air inside the condensation box. After the first heat sink and the second heat sink come into contact with the water vapor in the humid hot air, the water vapor is liquefied.

[0015] 3. The utility model achieves the effect of accelerating the flow of air near the first heat sink and the second heat sink above the condensation box by arranging a fan frame and a ventilation fan, which is beneficial to the condensation and liquefaction of water vapor in the humid hot air inside the condensation box. After the ventilation fan inside the fan frame works, the external cold air blows to the first heat sink and the second heat sink above the condensation box, and the fast-flowing air takes away the heat of the first heat sink and the second heat sink, reducing the temperature of the first heat sink and the second heat sink. After the first heat sink and the second heat sink come into contact with the humid hot air inside the condensation box, the water vapor in the humid hot air is cooled and liquefied.

[0016] 4. The utility model achieves the effect of sealing the gap between the movable cover and the plastic runway surface by arranging a sealing strip, a clamping protrusion and a clamping groove. The sealing strip contacts the plastic runway surface to seal and reduce the circulation of hot and cold air inside and outside the movable cover, thereby reducing heat loss. At the same time, the sealing strip and the movable cover are clamped and fixed by the clamping protrusion and the clamping groove, which facilitates the replacement of the sealing strip after wear.
