Description

Technical Field

[0001] The utility model relates to the field of pipeline blocking, in particular to a reverse air blocking device. Background Art

[0002] The iron outlet of the iron remover on the dry purification production line is affected by the operation process of the iron remover. During operation, there is negative pressure in the entire iron remover and the iron outlet pipeline, and the iron outlet is facing the air. On-site observation at the iron outlet shows that many smaller particles of iron powder fall to the iron outlet along with the large particles and are sucked back again, resulting in the presence of many fine iron particles in the finished product. Utility Model Content

[0003] In view of the above technical problems in the related art, the utility model provides a reverse wind blocking device, which can solve the above problems.

[0004] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:

[0005] A reverse wind blocking device, characterized in that it includes a sleeve, a support frame is extended outside one end of the sleeve, a clamping ring is connected to the end of the support frame, a connecting rod is matched inside the clamping ring, an wind blocking plate is provided at the lower end of the connecting rod, and a counterweight block is provided at the upper end of the connecting rod.

[0006] Furthermore, the other end of the sleeve is matched with an iron outlet, and a hoop is arranged on the outer side of the junction between the sleeve and the iron outlet.

[0007] Furthermore, the diameter of the air blocking plate matches the diameter of the sleeve.

[0008] Furthermore, the material of the wind blocking plate includes aluminum and iron.

[0009] Furthermore, the diameter of the sleeve is slightly larger than the diameter of the tap hole.

[0010] The beneficial effects of the utility model are as follows: an air blocking device is added to the iron outlet of the iron remover, and the air blocking device will block the iron outlet during normal operation. When there is a lot of iron slag inside, the air blocking device will be pushed open due to gravity, and when the iron slag falls, the air blocking plate will automatically close, thereby improving the iron removal efficiency.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0018] like Figure 1-2 As shown, according to the utility model, a reverse wind blocking device is disclosed, including a sleeve 2, a support frame 3 is extended outside one end of the sleeve 3, a clamping ring 4 is connected to the end of the support frame 3, a connecting rod 6 is matched inside the clamping ring 4, a wind blocking plate 7 is provided at the lower end of the connecting rod 6, and a counterweight block 5 is provided at the upper end of the connecting rod 6.

[0019] In one embodiment of the utility model, the other end of the sleeve 2 is matched with the iron outlet 1, and a hoop is arranged outside the junction of the sleeve 2 and the iron outlet 1; the diameter of the air blocking plate 7 matches the diameter of the sleeve 2. The material of the air blocking plate 7 includes aluminum and iron; the diameter of the sleeve 2 is slightly larger than the diameter of the iron outlet 1;

[0020] This device is mainly aimed at the iron outlet of the iron remover on the dry purification production line. Affected by the operation process of the iron remover, there is negative pressure in the entire iron remover and the iron outlet pipeline during operation, and the iron outlet is facing the air. On-site observation of the iron outlet shows that many smaller iron powder particles fall to the iron outlet with large particles and are sucked back again, resulting in a large number of fine iron particles in the finished product. Therefore, a wind blocking device is added to the slag outlet of the iron remover. During normal operation, the wind blocking device will block the iron outlet. When there is a lot of iron slag inside, it will be pushed open by gravity. When the iron slag falls, the wind blocking plate will automatically close.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
