In the filtering apparatus provided in this embodiment, the inlet 111 of the main pipeline 110 is provided with an external medium supply device, specifically, the inlet 111 of the main pipeline 110 is connected with an air source supply device, an external air source is provided with compressed air by an air compressor, the compressed air flows from the inlet 111 to the first outlet 112 in the main pipeline 110, during the flowing process, due to the arrangement of the filter screen 200, the compressed air is subjected to the filtering action of the filter screen 200, so that the filtered matters such as dust, impurities, and condensed water carried in the compressed air are blocked and intercepted by the filter screen 200, when a certain amount of filtered matters such as dust, impurities, and condensed water are accumulated on the filter screen 200, the filtered matters can fall down to the lower end of the filter screen 200 under the action of gravity, due to the communication between the branch pipeline 120 and the main pipeline 110, the filtered matters such as dust, impurities, and condensed water enter the branch pipeline 120, because the branch pipeline 120 has the second outlet 121, therefore, the filtered matters such as dust, impurities and condensed water in the branch pipeline 120 can be discharged from the second outlet 121 through the second outlet 121, and then the problem that the filtered matters such as dust, impurities and condensed water are accumulated on the filter screen 200 to block the filter screen 200 can be effectively relieved, so that the smoothness of the filter screen 200 is ensured to a certain extent, the normal use of the filter device is ensured, and the normal operation of the whole ash conveying system is further ensured.

It should be noted here that, firstly, considering that the filtered matters such as dust, impurities, condensed water and the like fall down under the gravity, in the present embodiment, it is preferable to provide the branch pipeline 120 at the lower portion of the main pipeline 110, may be a straight lower portion, or an oblique lower portion that is rotated by a certain angle around the axis of main pipe 110, so that the filtered matters such as dust, impurities, condensed water, etc. intercepted by the filter screen 200 can fall into the branch pipeline 120, in the embodiment, preferably, the branch pipeline 120 is located right below the main pipeline 110, that is, the plane where the axis of the main pipeline 110 and the axis of the branch pipeline 120 are located is a vertical plane, of course, branch line 120 may be located at the same level as main line 110, and in this case, the filtered matter intercepted by the filter screen 200 falls and is deposited at the lower end of the filter screen 200, and gradually moves into the branch pipeline 120 along with the accumulation of the filtered matter; secondly, the axis of the branch pipeline 120 and the axis of the main pipeline 110 form a certain included angle and are approximately Y-shaped, so that a Y-shaped filtering device is formed; thirdly, when the second outlet 121 is not provided with a container for holding the filtered substance, in order to ensure that the compressed gas does not leak from the second outlet 121, in this embodiment, an openable or closable sealing cover may be further provided at the second outlet 121, and after the filtering apparatus works for a period of time, the sealing cover is manually opened, so that the filtered substance accumulated in the branch pipeline 120 can be discharged from the second outlet 121, and the filtering net 200 is ensured not to be blocked by the filtered substance such as dust, impurities, condensed water, and the like.

The specific structure of the filter device will be described in detail below with reference to fig. 1 and 2, specifically as follows:

in this embodiment, preferably, the branch pipeline 120 is disposed right below the main pipeline 110, and an included angle α is formed between the axis of the branch pipeline 120 and the flowing direction of the medium in the main pipeline 110, where α is an acute angle; specifically, the branch pipe 120 is formed by extending downward from the lower sidewall of the main pipe 110, and since the compressed gas flows from the inlet 111 of the main pipe 110 to the first outlet 112, the filtered substances such as dust, impurities, and condensed water intercepted by the filter screen 200 are more likely to fall into the branch pipe; on this basis, the second outlet 121 end of the branch pipeline 120 is offset along the flow direction of the compressed air relative to the intersection position of the branch pipeline 120 and the main pipeline 110, that is, the branch pipeline 120 is inclined from top to bottom towards the flow direction of the compressed air to conform to the flow of the compressed air, and a part of the large-particle filtered substance falls into the branch pipeline 120 under the action of gravity when flowing along with the compressed air, so that the part of the large-particle filtered substance is easier to enter into the branch pipeline 120 due to the inclined arrangement of the branch pipeline 120 relative to the main pipeline 110.

Preferably, the included angle α ranges from 30 ° to 80 °, and includes 30 °, 40 °, 45 °, 50 °, 60 °, 70 ° and 80 °, and of course, in other embodiments, other angles may be provided, and the specific degree of the included angle is not limited as long as the actual requirement can be met.

In some embodiments, the branch pipe 120 is fixed to the side wall of the main pipe 110 by welding so as to seal the connection between the branch pipe 120 and the main pipe 110, but in other embodiments, the branch pipe 120 and the main pipe 110 may be integrally formed so as to form the delivery pipe 100 in a Y shape.

As a more preferable embodiment, the filter screen 200 includes a first filter portion 210, the first filter portion 210 is disposed at the connection position of the branch pipeline 120 and the main pipeline 110, the first filter portion 210 is located downstream of the third outlet 113 along the flowing direction of the medium, specifically, as shown in fig. 1 and 2, the top end of the first filter portion 210 is connected to the top inner side wall of the main pipeline 110, and the bottom end of the first filter portion 210 is located at the bottom of the main pipeline 110 and is located at a side position of the third outlet 113 close to the first outlet 112. By providing the first filtering portion 210, the main pipeline 110 is divided into a feeding section (the left side of the first filtering portion 210 in fig. 1 and 2) and a discharging section (the right side of the first filtering portion 210 in fig. 1 and 2), so that when the compressed air passes through the first filtering portion 210, filtered matters such as dust, impurities, condensed water and the like in the compressed air are intercepted by the first filtering portion 210, fall into the branch pipeline 120 under the action of gravity, and are discharged through the second outlet 121. Therefore, the filtering effect can be ensured, and the filtered substances such as dust, impurities, condensed water and the like can not be accumulated at the first filtering part 210 in a large amount, so that the smoothness of the first filtering part 210 is ensured, and the normal use of the filtering device is further ensured.

Further, in consideration of the specific shape of the conveying pipeline 100, that is, the arrangement form between the branch pipeline 120 and the main pipeline 110, in this embodiment, the second filtering portion 220 is connected to or integrally formed at the lower end of the first filtering portion 210, specifically, the second filtering portion 220 is concave and embedded into the branch pipeline 120, and the concave opening 421 faces the third outlet 113, so that the first filtering portion 210 and the second filtering portion 220 together form the angular filtering net 200, the compressed air can be filtered through the first filtering portion 210, and the stability of installation of the filtering net 200 is ensured by embedding the second filtering portion 220 in the branch pipeline 120, so that the filtering net 200 is not displaced or deformed when bearing the pressure of the compressed air, and the normal use of the filtering apparatus is ensured.

It should be noted that, since the filtered substances intercepted by the first filtering portion 210 fall into the second filtering portion 220, in order to ensure that the filtered substances can be discharged from the second outlet 121, in this embodiment, the aperture of the mesh of the second filtering portion 220 at the position opposite to the second outlet 121 may be set relatively large, so that the filtered substances falling into the branch pipe 120 can pass through the second filtering portion 220 and be discharged from the second outlet 121.

As a more preferable embodiment, a pneumatic valve 300 is provided at the first outlet 112 of the main pipeline 110, the pneumatic valve 300 having an input end inserted into the end of the first outlet 112 of the main pipeline 110 and an output end for connection with a next-stage device, so that the compressed gas filtered by the filter net 200 enters through the input end of the pneumatic valve 300 and flows into the next-stage device through the output end.

Considering that the filtered materials such as dust, impurities and condensed water discharged from the second outlet 121 out of the filtering apparatus will have a certain influence on the external environment to some extent, in this embodiment, a collecting container 400 is disposed at the second outlet 121, the collecting container 400 has a collecting port, and the collecting port is communicated with the second outlet 121, so that the filtered materials discharged through the second outlet 121 enter the collecting container 400 through the collecting port to be collected, thereby effectively alleviating the problem that the filtered materials are discharged to have influence on the external environment.

Further, the collecting container 400 includes a collecting ball 410, and a ball float valve 430 of the output pipeline 420, and specifically, the top of the collecting ball 410 is communicated with the second outlet 121, so that filtered materials such as dust, impurities, condensed water and the like in the branch pipeline 120 enter the collecting ball 410 through the second outlet 121; one end of the output line 420 is connected to a region of the collection ball 410 near the lower portion, and a float valve 430 is provided in the collection ball 410, the float valve 430 being located at an opening 421 of the output line 420, the output line 420 being able to be opened or closed by the float valve 430. Specifically, the ball float valve 430 may be disposed at the opening 421 of the output pipeline 420 through some limiting structures or suspension structures, when the amount of condensed water accumulated in the collection ball 410 is large, the ball float valve 430 is lifted up under the action of buoyancy, so that the ball float valve 430 is separated from the opening 421 to open the opening 421, and at this time, some filtered matters in the collection ball 410 can be discharged to a designated position through the output pipeline 420 along with the condensed water; when the condensed water in the collection ball 410 is partially discharged and the buoyancy generated by the condensed water is not enough to support the ball float valve 430, the ball float valve 430 moves down to the opening 421 again and seals the opening 421 under the combined action of gravity and a limiting structure or a suspension structure, and at this time, the filtered substances in the collection ball 410 cannot be discharged to the outside through the output pipeline 420; along with the normal use of the filtering device, the filtered matters such as dust, impurities, condensed water and the like are continuously collected by the collecting ball 410, when the condensed water reaches a certain amount, the ball float valve 430 is lifted up again to open the opening 421, and the process is circulated, so that the automatic collection and discharge of the filtered matters such as dust, impurities, condensed water and the like are realized, the filtering device is not easy to block, the normal use of the filtering device is ensured, the convenience of the collection and the discharge of the filtered matters is improved, and two purposes are achieved at one stroke.
