Description

Technical Field

[0001] The utility model relates to the technical field of plastic track raw material processing, in particular to a plastic track raw material stirring device with an exhaust gas treatment mechanism. Background Art

[0002] The plastic track is also called the track and field sports track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The raw materials of the plastic track need to be stirred during processing. The existing plastic track raw material stirring device is generally open. Not only during the stirring process, but also during the unloading process, there will be volatilization of waste gas. However, since waste gas will be emitted during the stirring process of the plastic runway raw materials, as the stirring proceeds, the emission of waste gas will be accelerated, thereby polluting the air and damaging the health of nearby construction workers. For this reason, a plastic runway raw material stirring device with a waste gas treatment mechanism is designed to facilitate the treatment of waste gas during the stirring and unloading process, avoid the overflow of waste gas in the mixing tank during stirring or unloading, and ensure the construction environment of the construction workers.

[0013] Compared with the prior art, the present invention provides a plastic track raw material stirring device with an exhaust gas treatment mechanism, which has the following beneficial effects:

[0014] The plastic runway raw material stirring device with an exhaust gas treatment mechanism can be used as a feeding port through the feeding port, which is convenient for pouring the plastic runway raw material into the stirring tank, and the feeding port is conveniently sealed by the sealing sliding cover. When stirring through the stirring structure, the air outlet can be connected to the exhaust pipe by adjusting the three-way valve, and then the exhaust structure is started to suck the exhaust gas in the stirring tank into the exhaust gas filter box through the connecting pipe. After being filtered by the exhaust gas filter box, the exhaust gas is discharged through the air outlet and the exhaust pipe and the exhaust structure. After a period of time, when the air pressure in the stirring tank drops to a certain value, the exhaust structure can be closed and adjusted. Adjust the three-way valve to connect the natural exhaust pipe with the air outlet, so that under the action of internal and external atmospheric pressure, the outdoor air can be drawn into the exhaust gas filter box through the natural exhaust pipe and the air outlet and poured into the mixing tank through the connecting pipe to adjust the pressure difference between the inside and outside of the mixing tank. Then the above operation can be repeated to ensure that the exhaust gas in the mixing tank does not overflow. During the process, the material can be unloaded through the unloading structure. The plastic runway raw material mixing device with an exhaust gas treatment mechanism is convenient for treating the exhaust gas during the mixing and unloading process, avoiding the overflow of the exhaust gas in the mixing tank during the mixing or unloading process, and ensuring the construction environment of the construction personnel.
