Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, an air inlet pipe in a kettle for a vertical wet-process water glass reaction kettle comprises an air inlet pipe 1, a plurality of flow guide rings 2 and a sealing sheet 3, wherein the air inlet pipe 1 is a round pipe structure with an open top and a closed bottom, a plurality of air outlets 101 are arranged on the side wall of the air inlet pipe 1 along the length direction of the air inlet pipe 1 and are layered and communicated around the axis of the air inlet pipe, the heights of the air outlets 101 on the same layer are consistent, and two symmetrically arranged sliding grooves 102 are arranged at the lower part of the inner wall of the air; the guide ring 2 is a circular truncated cone structure with openings at the top and the bottom and communicated with each other, the bottom of the side wall of the guide ring 2 is cast on the inner wall of the air inlet pipe 1, the guide rings 2 are arranged in layers, one guide ring 2 is correspondingly arranged at the position of each layer of air outlet 101, and the air outlets 101 of the same layer are flush with the bottoms of the guide rings 2; the sealing plate 3 is the bowl form structure, and the both sides of sealing plate 3 are casted the lug of shape size and spout 102 looks adaptation, and sealing plate 3 is through these two lug sliding connection in the inside of two spout 102, and sealing plate 3 sets up with intake pipe 1 is coaxial, fixedly connected with buffer spring 4 between the bottom surface of sealing plate 3 and intake pipe 1.

Through the technical scheme, high-temperature steam is injected into the air inlet pipe 1 at a high flow speed, in the process that the steam is injected towards the bottom direction of the air inlet pipe 1, part of the high-temperature steam is blocked by the flow guide ring 2, the flow direction of the part of the high-temperature steam is changed after the part of the high-temperature steam is guided by the circular truncated cone-shaped flow guide ring 2, so that the part of the high-temperature steam can directly flow to the air outlet 101 along the side wall of the flow guide ring 2, the part of the high-temperature steam can be more quickly and directly sprayed out from the air outlet 101, the impact force is greatly reduced when the high-temperature steam flows to the bottom of the air inlet pipe 1 after being guided by the flow guide ring 2, the air inlet pipe 1 forms a double-layer sealing structure by the bottom surface and the sealing sheet 3, when the bottom of the air inlet pipe 1 is impacted, the buffer spring 4 is compressed and generates reverse elasticity, so that the impact force is further buffered, and the bottom of the device is effectively prevented from being damaged and perforated due to long-term impact of high-temperature steam; this device adopts a plurality of distributed gas outlets 101, and steam no longer concentrates on a position to spray, but spouts in to reation kettle along these gas outlets 101 dispersions, and the resistance that receives in reation kettle's reaction raw materials after steam jet goes out in addition also comparatively disperses, therefore the impact of air current to reation kettle is little to reation kettle's vibrations is also little, the utility model discloses long-term the use can not cause damage, safe and reliable to reation kettle yet.

Further, as shown in fig. 1-3, an isolation net 1011 is arranged inside the gas outlet 101, so that solid reactants in the reaction kettle can be prevented from entering the gas inlet pipe 1 along the gas outlet 101, and blocking and accumulation are formed at the bottom of the gas inlet pipe 1 and on the flow guide ring 2.

Further, as shown in fig. 1-3, high-temperature steam cannot penetrate through the sealing sheet 3, so that the air outlets 101 are all arranged above the position of the sealing sheet 3, and the air outlets 101 are uniformly arranged at equal intervals, so that the steam flow ejected from each part of the side wall of the air inlet pipe 1 is the same, and the air inlet pipe 1 is ensured to uniformly eject high-temperature steam into the reaction kettle.

Further, as shown in fig. 3 and 5, the bottom portions of the seal fin 3 and the intake pipe 1 are both arc-shaped, and this shape can reduce the impact force caused by the high flow rate steam, and further cushion the impact force.

Further, intake pipe 1 and its internals are 316L stainless steel, and this kind of material has corrosion-resistant, antifriction's advantage, has effectively prolonged the utility model discloses a life.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
