Technical Field

[0001] The utility model belongs to the technical field of exhaust gas of a foam board beating machine, and in particular relates to a silencing device for exhaust gas of a foam board beating machine. Background Art

[0002] The foam board making machine is a briquetting machine equipment used for compressing EPS foam plastics. In the production process of foam, water vapor is needed, and the used water vapor is directly discharged into the air through a pipe. Due to the high steam pressure and the fast steam discharge speed in the pipe, considerable air noise will be generated. Working in this environment for a long time will cause impact on the workers' eardrums and affect their health. In the prior art, in order to reduce the noise during steam discharge, the pipe is generally extended, but extending the pipe will reduce the steam discharge speed and affect production efficiency; and because the steam in the pipe is liquefied, liquefied water will flow out of the pipe, causing pollution to the environment. Therefore, in the prior art, when the foam board making machine discharges high-temperature steam, the noise is large and the sewage cannot be effectively collected, polluting the environment. Utility Model Content

[0003] In order to solve the technical problem that the existing foam board machine has a large noise when releasing steam and the sewage cannot be effectively collected, the utility model provides a silencing device for exhausting the foam board machine, including an exhaust mechanism, a supporting mechanism for supporting is provided at the bottom of the exhaust mechanism, the supporting mechanism includes a plurality of vertically arranged legs, a supporting plate for supporting the exhaust mechanism is fixed at the top of the legs, and a base is fixed at the bottom of the legs. The exhaust mechanism includes a first exhaust pipe, a second exhaust pipe, a third exhaust pipe and a fourth exhaust pipe which are connected and arranged in sequence from left to right, and the inner diameters of the first exhaust pipe, the second exhaust pipe, the third exhaust pipe and the fourth exhaust pipe are increased in sequence, so that the cross-sectional area of ​​the pipeline through which the high-temperature steam flows is gradually increased, and the flow rate of the high-temperature steam is gradually reduced, so as to achieve the purpose of reducing noise, the left end of the first exhaust pipe is detachably fixedly connected to the exhaust port of the foam board machine, the right end of the fourth exhaust pipe is sealed, and the top of the fourth exhaust pipe is provided with a plurality of exhaust holes arranged at intervals from left to right, and the diameters of each exhaust hole are increased in sequence from left to right, so that the high-temperature steam entering the fourth exhaust pipe is effectively discharged. A drainage hole is provided at the bottom end of the fourth exhaust pipe, and a water storage mechanism for collecting water is provided at the drainage hole. The water storage mechanism includes a water tank. The top end of the water tank is connected to the drainage hole. A vertical drainage pipe is fixed to the bottom end of the water tank. A sealing cover is detachably provided at the lower end of the drainage pipe. Water droplets liquefied by pre-cooling of high-temperature water vapor fall down and flow into the water tank through the drainage hole after being gathered. After being used for a period of time, the sealing cover is removed, and the water in the water tank is discharged through the drainage pipe and centrally treated, which can reduce pollution to the environment and avoid sewage flowing everywhere and affecting operations.

A supporting mechanism 2 is provided at the bottom end of the exhaust mechanism 1 for supporting the exhaust mechanism. The supporting mechanism 2 includes a plurality of vertically arranged legs 21. A supporting plate 22 for supporting the exhaust mechanism 1 is fixed to the top end of the legs 21, and a base 23 is fixed to the bottom end of the legs 21. The exhaust mechanism 1 includes a first exhaust pipe 11, a second exhaust pipe 12, a third exhaust pipe 13 and a fourth exhaust pipe 14 which are sequentially connected from left to right, and the inner diameters of the first exhaust pipe 11, the second exhaust pipe 12, the third exhaust pipe 13 and the fourth exhaust pipe 4 increase sequentially, which can gradually increase the cross-sectional area of ​​the pipe through which the high-temperature steam flows, and gradually reduce the flow rate of the high-temperature steam, thereby achieving the purpose of reducing noise. The left end of the first exhaust pipe 11 is detachably fixedly connected to the exhaust port of the foam board making machine, the right end of the fourth exhaust pipe 14 is sealed, and the top end of the fourth exhaust pipe 14 is provided with a plurality of exhaust holes 15 arranged at intervals from left to right, and the diameters of each exhaust hole 15 increase sequentially from left to right, so that the high-temperature steam entering the fourth exhaust pipe 14 can be effectively discharged. A drainage hole 16 is provided at the bottom end of the fourth exhaust pipe 14, and a water storage mechanism 3 for collecting water is provided at the drainage hole 16. The water storage mechanism 3 includes a water tank 31. The top of the water tank 31 is connected to the drainage hole 16. A vertical drainage pipe 32 is fixed to the bottom end of the water tank 31. A sealing cover 33 is detachably provided at the lower end of the drainage pipe 32. Water droplets pre-cooled and liquefied by high-temperature water vapor fall down and flow into the water tank 31 through the drainage hole 16 after being gathered. After being used for a period of time, the sealing cover 33 is removed, and the water in the water tank 31 is discharged through the drainage pipe 32 and centrally treated, which can reduce pollution to the environment and avoid sewage flowing everywhere and affecting operations.

When the high-temperature steam is discharged, the high-temperature steam flows through the first exhaust pipe 11, the second exhaust pipe 12, the third exhaust pipe 13 and the fourth exhaust pipe 14 from left to right at a time. The inner diameter area of ​​the high-temperature steam flowing through the pipeline increases successively, and the flow rate of the high-temperature steam decreases successively, and finally flows out from the exhaust hole 15 at the top of the fourth exhaust pipe 14. Part of the water vapor is pre-cooled and liquefied into small water droplets, and converges and flows into the water tank 31. When the liquefied water in the water tank 31 needs to be discharged, the sealing cover 33 is removed, and the liquefied water is discharged from the water tank 31 through the drain pipe 32.
