Description

Technical Field

[0002] When the setting machine is working, high-temperature exhaust gas flows through the exhaust pipe and is discharged synchronously. Theoretically, the discharge amount of high-temperature exhaust gas discharged from the exhaust pipe per unit time is generally the set value.

[0003] However, in actual work, the actual emission of high-temperature exhaust gas discharged through the exhaust duct may be higher or lower than the set value. If the actual emission of high-temperature exhaust gas discharged through the exhaust duct is higher than the set value, it will lead to excessive exhaust gas emission and waste of heat energy. If the actual emission of high-temperature exhaust gas discharged through the exhaust duct is lower than the set value, it may be due to partial blockage of the ventilation channel of the printing and dyeing equipment, resulting in emission lower than the set value, which will cause the temperature inside the smoke duct of the setting machine to be too high or smoke to come out of the cloth inlet and outlet of the setting machine.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses an exhaust gas flow emission monitoring device, which is used to facilitate staff to inspect and repair an exhaust pipe according to the actual exhaust volume of the exhaust pipe.

[0033] refer to Figure 1 , Figure 2 A waste gas flow emission monitoring device includes a monitoring pipe 110, which is used to be integrated in an exhaust pipe and connected to the exhaust pipe. A negative pressure sensor 111 is arranged on the monitoring pipe 110, and the negative pressure sensor 111 is partially embedded in the monitoring pipe 110. In this embodiment, the monitoring pipe 110 and the negative pressure sensor 111 correspond to each other one by one and are provided in plurality. The plurality of monitoring pipes 110 are respectively integrated at the outlet of the exhaust main pipe 11 and the plurality of exhaust branch pipes 12. The bottom of one side of the printing and dyeing equipment 10 is connected to the plurality of exhaust branch pipes 12, and one end of the exhaust branch pipe 12 away from the printing and dyeing equipment 10 is connected to the exhaust main pipe 11. The negative pressure sensor 111 is partially embedded in the monitoring pipe 110, which can monitor the actual displacement in the exhaust pipe in real time, so that the staff can inspect and repair the exhaust pipe according to the actual displacement of the exhaust pipe.

[0034] Further, refer to Figure 2 , Figure 3 Each monitoring pipe 110 is provided with an alarm 112 and an alarm light 113, which are electrically connected to the negative pressure sensor 111. When the negative pressure sensor 111 detects that the actual discharge volume in the exhaust pipe is too high or too low, the alarm 112 and the alarm light 113 will work.

[0035] The negative pressure sensor 111 is divided into a monitoring end 1111 and a display end 1112. The monitoring end 1111 is embedded in the monitoring pipe 110 and is used to monitor the actual displacement in the exhaust pipe. The display end 1112 is exposed to the monitoring pipe 110 and is used to display the actual displacement in the exhaust pipe. The display end 1112 is coaxially sleeved with a mounting ring 120 at one end close to the monitoring end 1111. The end face of the mounting ring 120 close to the monitoring end 1111 is used to contact the outer wall of the monitoring pipe 110. The mounting ring 120 is provided on the outer wall of the monitoring pipe 110. A plurality of mounting bolts 121 are axially penetrated along the mounting ring 120. In the present embodiment, a total of four mounting bolts 121 are penetrated. The four mounting bolts 121 are penetrated in the mounting ring 120 at equal angles along the circumference of the mounting ring 120. The mounting bolts 121 penetrate the mounting ring 120 radially and then penetrate into the wall of the monitoring pipe 110 and are threadedly connected to the monitoring pipe 110, thereby realizing a detachable connection between the mounting ring 120 and the negative pressure sensor 111 and the monitoring pipe 110.

[0036] refer to Figure 4 , Figure 5 In order to facilitate the operator to determine whether the negative pressure sensor 111 is installed in place, a positioning piece 130 is provided on the side wall of the monitoring end 1111, and a monitoring hole 131 for the monitoring end 1111 to be embedded is penetrated on the monitoring pipe 110. A positioning hole 132 for the positioning piece 130 to be embedded is opened on the monitoring pipe 110, and the positioning hole 132 is located on the hole wall of the monitoring hole 131. In this embodiment, a total of four positioning pieces 130 are provided, and the four positioning pieces 130 are arranged on the side wall of the monitoring end 1111 at equal angles along the circumference of the mounting ring 120. The positioning holes 132 correspond to the positioning pieces 130 one by one, and the four positioning holes 132 are opened on the hole wall of the monitoring hole 131 at equal angles along the circumference of the mounting ring 120.

[0037] Specifically, the positioning member 130 includes a positioning hemisphere 1301 and a return spring 1302. An embedding groove 133 for embedding the positioning member 130 is radially opened along the mounting ring 120 on the side wall of the monitoring end 1111.

The positioning hemisphere 1301 is partially embedded in the embedding groove 133. The positioning hemisphere 1301 is used to slide and embed into the positioning hole 132. During the process of embedding the negative pressure sensor 111 into the monitoring pipeline 110, the return spring 1302 is compressed and the positioning hemisphere 1301 is completely embedded in the embedding groove 133. When the positioning hemisphere 1301 is aligned with the positioning hole 132, the rebound force of the return spring 1302 causes the positioning hemisphere 1301 to be embedded in the positioning hole 132, which is convenient for the operator to judge whether the negative pressure sensor 111 is installed in place.

[0038] refer to Figure 3 , Figure 4 and Figure 5In order to improve the connection sealing between the negative pressure sensor 111 and the monitoring pipe 110, a rubber ring 122 is sleeved on one end of the display end 1112 close to the monitoring end 1111, and one end face of the rubber ring 122 is connected to one end face of the mounting ring 120, and the other end face of the rubber ring 122 is used to contact the outer wall of the monitoring pipe 110. A rubber ring 134 is coaxially sleeved on the monitoring end 1111, and the inner wall of the rubber ring 134 is tightly attached to the outer wall of the monitoring end 1111, and the outer wall of the rubber ring 134 is tightly attached to the outer wall of the monitoring end 1111. The wall is used to fit tightly against the hole wall of the monitoring hole 131. In the present embodiment, four through holes 135 are radially penetrated on the rubber ring 134. The four through holes 135 correspond one to one with the four positioning holes 132. The four through holes 135 penetrate the rubber ring 134 at equal angles along the circumference of the rubber ring 134. The rubber ring 122 is sleeved on the display end 1112, and the rubber ring 134 is sleeved on the monitoring end 1111 to increase the connection sealing between the negative pressure sensor 111 and the monitoring pipeline 110.
