As shown in fig. 1 to 3, the present embodiment provides an anti-blocking device, which includes a main pipeline 1, a main air supply 2 and a blowing-assisting assembly. The main pipeline 1 is used for discharging materials along a first direction, and the main pipeline 1 is sequentially provided with a first flowmeter 11, a second flowmeter 12 and a third flowmeter 13 along the first direction. The blowing-aid assembly comprises a main gas source 2, a first blowing-aid pipe 3, a second blowing-aid pipe 4, a third blowing-aid pipe 5, a first valve body 31, a second valve body 41 and a third valve body 51.

Alternatively, the first valve body 31, the second valve body 41 and the third valve body 51 are all ball valves.

In the implementation, the anti-blocking device is provided with the plurality of flowmeters on the main pipeline 1, and then the blowing-assisted pipes are respectively arranged at the upstream of each flowmeter, so that when the reading of one flowmeter is small, the corresponding valve body can be opened to allow the airflow to ventilate through the blowing-assisted pipes, the downstream impulsive force is improved, and the blockage of the section is eliminated; divide into the multistage with main line 1, every section all sets up the mode of helping the blowpipe, has reduced the degree that the material blockked up, has improved clear stifled efficiency and effect.

After the operation workman sees the count of flowmeter, the count of finding the flowmeter is less than the default, then goes the operation valve body, eliminates the jam through the air current, and this process reaction cycle is long, and easy reading mistake or judge the error, probably leads to blockking up further aggravation, leads to the clearance effect variation.

In order to avoid the above situation, in this embodiment, preferably, the anti-blocking device further includes a controller (not shown in the figure) and a first electromagnetic valve (not shown in the figure), and the controller is electrically connected to the first electromagnetic valve and the first flowmeter 11 respectively; the first electromagnetic valve is arranged on the first auxiliary blowing pipe 3 and used for controlling the opening and closing of the first valve body 31, the controller is used for detecting the counting of the first flowmeter 11 and controlling the first electromagnetic valve to act when the counting of the first flowmeter 11 is smaller than a preset value, the first valve body 31 is opened, and airflow enters the main pipeline 1 through the first auxiliary blowing pipe 3. When the reading of the first flowmeter 11 is smaller than the preset value through the arrangement, the first electromagnetic valve is controlled to act through the controller, the first valve body 31 is further controlled to be opened, at the moment, the airflow enters the main pipeline 1 through the first blow-assisting pipe 3, the blocking objects in the main pipeline 1 are cleaned, and when the counting of the first flowmeter 11 is larger than the preset value, the first valve body 31 is closed through the first electromagnetic valve by the controller. This setting has realized the automatic clear stifled of pipeline between first flowmeter 11 and the entry of main pipeline 1 through the automatic switching of first valve body 31, avoids the condition of data misreading or erroneous judgement, has shortened the reflection cycle, has improved cleaning efficiency. It should be noted that the control principle of the controller reading the data of the first flow meter 11 to control the first electromagnetic valve to open or close the first valve body 31 is conventional in the art, and therefore, the operation principle thereof is not described herein again.
