[0030] The dust collector is a device for separating dust in dust-containing airflow. In order to avoid the damage of the dust collector caused by the spark entering the dust collector, even the fire, the spark catcher is usually installed in front of the dust collector. But in the actual production process, researchers found that the traditional spark catcher will cause the spark to break through the interception mechanism of the spark catcher due to inertia when the flow rate of the dust-containing airflow is too fast, resulting in the leakage of the spark into the dust collector; that is, the traditional spark catcher has the technical problem of poor interception effect.

[0031] The utility model provides a spark catcher, aims at solving the technical problem of poor interception effect of the spark catcher.

[0032] Please refer to Figs. 1 to 3 In an embodiment of the utility model, the spark catcher comprises a shell 100, a first baffle 200 and an interception assembly 300, the shell 100 is provided with a containing cavity 110, an air inlet 120 and an air outlet 130, the first baffle 200 is arranged in the containing cavity 110, the air inlet 120 is arranged towards the first baffle 200, the interception assembly 300 is arranged in the containing cavity 110 and is connected with the first baffle 200, and the interception assembly 300 and the first baffle 200 separate the containing cavity 110 to form an air inlet cavity 111 and an air outlet cavity 112, the air inlet 120 is communicated with the air inlet cavity 111, and the air outlet 130 is communicated with the air outlet cavity 112.

[0033] The technical scheme of the utility model discloses first baffle 200 is arranged in accommodating cavity 110, and air inlet 120 is arranged towards first baffle 200, and interception assembly 300 is intercepted, can improve the interception effect of spark trap, and then reduce the risk of spark leakage in dust-containing airflow to dust catcher.In this embodiment, first baffle 200 is arranged in accommodating cavity 110, and air inlet 120 is arranged towards first baffle 200, which can intercept sparks and dust in dust-containing airflow when dust-containing airflow enters accommodating cavity 110 through air inlet 120, and also can change the flow direction of dust-containing airflow, reduce the risk of sparks in dust-containing airflow directly breaking through the interception mechanism and leaking to the dust catcher through air outlet 130.Interception assembly 300 plays an interception role.And interception assembly 300 and first baffle 200 can also divide accommodating cavity 110 into air inlet cavity 111 and air outlet cavity 112 in structure, that is, interception assembly 300 and first baffle 200 can cut off the communication channel between air inlet 120 and air outlet 130 to avoid sparks leaking to the dust catcher directly through air inlet 120 and air outlet 130 with dust-containing airflow.Specifically, when dust-containing airflow enters accommodating cavity 110 from air inlet 120, dust-containing airflow will first collide with first baffle 200 and change the flow direction under the blocking action of first baffle 200, and then dust-containing airflow will pass through interception assembly 300 and enter the dust catcher through air outlet 130;During this process, the sparks in dust-containing airflow are intercepted twice by first baffle 200 and interception assembly 300, which can improve the interception effect of the spark trap and reduce the risk of spark leakage to the dust catcher.The spark trap is applied to the technical field of dust catcher auxiliary equipment.

[0034] In this embodiment, air inlet 120 and air outlet 130 are arranged on the two sides of shell 100, and first baffle 200 is arranged between air inlet 120 and air outlet 130.By arranging first baffle 200 between air inlet 120 and air outlet 130, sparks in dust-containing airflow can be intercepted, and the risk of sparks in dust-containing airflow directly breaking through the interception mechanism and leaking to the dust catcher through air outlet 130 can be reduced.

[0035] In the embodiment of the utility model, the first baffle 200 is inclined from the side close to the air inlet 120 to the side away from the air inlet 120 along the extension direction thereof, the intercepting assembly 300 is inclined from the side close to the air inlet 120 to the side away from the air inlet 120 along the extension direction of the first baffle 200, and the intercepting assembly 300 is connected to the side away from the air inlet 120 of the first baffle 200. In the embodiment, the first baffle 200 is inclined from the side close to the air inlet 120 to the side away from the air inlet 120 along the extension direction thereof, which can ensure the intercepting effect of the first baffle 200 and reduce the influence of the first baffle 200 on the flow rate of the dust-containing airflow. The intercepting assembly 300 is inclined from the side close to the air inlet 120 to the side away from the air inlet 120 along the extension direction of the first baffle 200, so that the lower end surface of the intercepting assembly 300 can intercept sparks, and the risk of clogging of the intercepting assembly 300 can be reduced. Specifically, when the dust-containing airflow passes through the intercepting assembly 300, the intercepting assembly 300 can intercept dust and sparks in the dust-containing airflow at the same time. As the spark catcher operates, dust accumulated on the surface of the intercepting assembly 300 will increase, which will inevitably clog the intercepting assembly 300 to some extent. However, in the spark catcher, the intercepting assembly 300 intercepts sparks with the lower end surface thereof. When the spark catcher stops operating or the intercepted dust accumulates too much, the dust will fall downward under the action of gravity and separate from the intercepting assembly 300.

[0036] In the embodiment of the utility model, the air inlet cavity 111 is provided with a second baffle 400, the second baffle 400 is located below the first baffle 200, and a communication port 410 for the dust-containing airflow to pass through is arranged between the first baffle 200 and the second baffle 400. The second baffle 400 arranged below the first baffle 200 can intercept sparks and dust in the dust-containing airflow and reduce the risk of spark leakage in the dust-containing airflow into the dust collector. Specifically, when the dust-containing airflow enters the containing cavity 110 from the air inlet 120, the dust-containing airflow will first collide with the first baffle 200 and change the flow direction under the blocking action of the first baffle 200, then the dust-containing airflow will collide with the second baffle 400 and change the flow direction again under the blocking action of the second baffle 400, then the dust-containing airflow will pass through the communication port 410 and the intercepting assembly 300 in turn, and finally enter the dust collector through the air outlet 130.

[0037] In an embodiment of the utility model, the spark catcher further includes a blocking plate 500, the blocking plate 500 is rotatably arranged on one side of the air inlet 120, and the blocking plate 500 can close the air inlet 120. Specifically, when the dust catcher catches fire, the sparks in the containing cavity 110 often backflow through the air outlet 130 and the air inlet 120, causing more serious accidents. The spark catcher can close the air inlet 120 when catching fire by arranging the blocking plate 500 at the air inlet 120, so as to reduce the risk of spark backflow. When the spark catcher is normally running, the dust-containing airflow drives the blocking plate 500 to rotate to open the air inlet 120.

[0038] In an embodiment of the utility model, the blocking plate 500 is rotatably arranged above the air inlet 120. When the spark catcher is normally running, the dust-containing airflow drives the blocking plate 500 to rotate to open the air inlet 120. When the spark catcher stops running, the blocking plate 500 will rotate under the action of its own gravity to close the air inlet 120. The spark catcher rotatably arranges the blocking plate 500 above the air inlet 120, so that the blocking plate 500 can close the air inlet 120 only under the action of its own gravity, which has the characteristics of simple structure and can reduce the manufacturing difficulty of the spark catcher. In addition, the blocking plate 500 can also be installed on both sides or the lower side of the air inlet 120. In order to ensure that the blocking plate 500 can close the air inlet 120, a spring or a torsional spring is also needed to be arranged to drive the blocking plate 500 to rotate and close the air inlet 120 when the spark catcher stops running.

[0039] In an embodiment of the utility model, the intercepting assembly 300 includes a first filter screen, a second filter screen and a third filter screen arranged in a stack, the first filter screen has the same intercepting aperture as the third filter screen, the first filter screen has a smaller filtering space than the second filter screen, and the first filter screen, the second filter screen and the third filter screen are arranged in a staggered manner. The three-layer filter screen with small-large-small intercepting apertures can increase the disengagement area of the intercepting assembly 300 and the dust-containing airflow when the dust-containing airflow passes through the intercepting assembly 300, and can better intercept small particles in the dust-containing airflow, improving the interception effect. In a specific embodiment, the first filter screen and the third filter screen can be 2*3mm wire mesh, and the third filter screen can be 5*5mm wire mesh.
