Description

Technical Field

[0001] The utility model relates to the technical field of aerogel felt preparation, in particular to a glue coating nozzle with a plate tower structure. Background Art

[0002] Aerogel felt is a lightweight thermal insulation material with a porous structure. It has excellent thermal insulation performance, and is also flexible, hydrophobic, and has a long service life. In the prior art, the process of producing aerogel felt mainly includes introducing the catalytic sol and the substrate for coating into a coating tray, and impregnating the substrate for gelation; wherein, the process of impregnating the substrate is to pump the catalytic sol into the coating tray, and then the substrate passes through the coating tray under the action of a belt to absorb the catalytic sol to form a wet gel felt.

[0003] However, in the existing production process, the sol and the catalyst are directly pumped to the coating tray through a connected pipe, and the mixing of the sol and the catalyst is achieved only by controlling the flow rate of the pump. Since the process is very rapid, the sol and the catalyst are mixed in a short time, resulting in uneven mixing and insufficient reaction, which can easily cause the wet gel felt to be partially gelled or not gelled, resulting in uneven aerogel on the substrate or partial lack of gel, thereby affecting product performance and reducing product yield and output; and if the sol and the catalyst are in contact for a long time, it is easy to cause the sol to directly gel in the coating tray or in the pipe, making the quality of the gel felt unstable, affecting production capacity, and even causing pipeline blockage, resulting in waste of manpower, material resources and resources. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a glue coating nozzle with a plate tower structure to solve the problems that the prior art lacks special equipment, resulting in less contact time between sol and catalyst, and uneven mixing, thereby affecting the gel effect of aerogel felt.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A glue spray nozzle with a plate tower structure comprises a tower body, wherein a liquid inlet hole is arranged at the top of the tower body and a liquid outlet hole is arranged at the bottom; a plurality of tower plates are arranged horizontally and staggeredly in the tower body; one end of the tower plate in the length direction is fixed to the inner wall of the tower body, and the other end is suspended and extends to the middle of the tower body and is slightly larger than the radius or width of the tower body; a liquid guide groove is arranged in the middle of the tower plate along the length direction, and a plurality of liquid passing holes are evenly arranged on both sides of the width direction of the liquid guide groove; the liquid guide grooves on two adjacent tower plates are in the same vertical plane, so that the liquid flows from top to bottom in turn along the direction of the liquid guide grooves of each tower plate, that is, the flow velocity of the liquid is changed and the length of the path through which the liquid flows is increased through the liquid guide grooves and liquid passing holes of each tower plate; the liquid inlet hole is arranged at one end of the top tower plate close to the inner wall.

[0007] Furthermore, the tower body is a cylindrical, quadrilateral or polygonal cylinder.

[0008] Furthermore, the height of the tower body is 30 cm - 60 cm, and the width is 30 cm - 60 cm.

[0009] Furthermore, the tower plate is strip-shaped, oval or semi-circular, with a length of 20 cm - 45 cm and a width of 20 cm - 40 cm.

[0010] Furthermore, the length of the liquid guiding groove runs through the length of the tower plate; the width is 15 cm - 30 cm.

[0011] Furthermore, the diameter of the liquid passing hole is 1 cm - 2 cm.

[0012] Furthermore, there are 3 - 11 layers of tower plates, and the spacing between the tower plates is 3 cm - 6 cm.

[0013] Furthermore, the glue spraying nozzle is detachably connected to the sol discharge pipeline, and a pump is connected to the pipeline.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The present utility model creatively designs a glue spraying nozzle with a novel tray tower structure. By arranging multiple layers of tower plates and providing liquid passing holes on each layer of tower plate, the liquid can be evenly distributed on the tower plate, enhancing the uniformity of the mixture of the catalyst and the sol, thereby enhancing the gel effect. At the same time, by arranging the liquid guiding groove, the liquid flow rate is increased, avoiding premature gelation caused by too long mixing time of the catalyst and the sol and blocking the nozzle.

[0016] In addition, the glue spraying nozzle is detachably connected to the sol discharge pipeline, which can avoid the blockage problem caused by the residual sol during continuous production. When the flow rate is unstable, it can be replaced and cleaned in time, improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment:

[0023] A glue spray nozzle with a plate tower structure comprises a tower body 1, wherein a liquid inlet hole 2 is provided on the top of the tower body 1, and a liquid outlet hole 6 is provided on the bottom; a plurality of tower plates 3 are horizontally and staggeredly arranged in the tower body 1; one end of the tower plate 3 in the length direction is fixed to the inner wall of the tower body 1, and the other end is suspended and extends to the middle of the tower body 1 and is slightly larger than the radius or width of the tower body 1; a liquid guide groove 4 is provided in the middle of the tower plate 3 along the length direction, and a plurality of liquid passing holes 5 are evenly provided on both sides of the liquid guide groove 4 in the width direction; the liquid guide grooves 4 on two adjacent tower plates 3 are in the same vertical plane, so that the liquid flows from top to bottom in turn along the direction of the liquid guide grooves 4 of each tower plate 3, that is, the flow velocity of the liquid is changed and the length of the path through which the liquid flows is increased through the liquid guide grooves 4 and the liquid passing holes 5 of each tower plate 3; the liquid inlet hole 2 is provided at one end of the top tower plate 3 close to the inner wall.

[0024] The utility model glue coating nozzle, by arranging liquid holes 5 on the tower plate 3, allows the liquid to be evenly distributed on the tower plate 3, thereby enhancing the uniformity of the mixing of the catalyst and the sol, thereby enhancing the gelling effect. The provision of the liquid guide groove 4 can increase the liquid flow rate, thereby avoiding premature gelling caused by the catalyst and the sol mixing time being too long. In addition, the parallel and staggered arrangement of the tower plates 3 allows the direction of the liquid flow to alternately change in different areas of the tower plate 3, while changing the flow rate of the liquid and increasing the length of the path through which the liquid flows. The change in the direction of the liquid helps the liquid cover more surfaces, thereby improving the uniformity of its distribution; the change in speed helps to break up the droplets, increase the surface area of ​​the liquid, thereby improving the uniformity; and the increase in the path length increases the residence time of the liquid on the tower plate 3, thereby improving the mixing effect of the sol and the catalyst.

[0025] In specific implementation, the tower body 1 is cylindrical, with a height of 40 cm and a diameter of 30 cm. The use of a cylindrical glue spray nozzle helps to reduce internal dead corners, thereby reducing the residue of sol, and is easy to clean and maintain. The size design of 40 cm in height and 30 cm in width makes it easy to control the sol flow rate inside the nozzle, avoiding the clogging of the nozzle due to the contact between the sol and the catalyst for too long. Different sizes of tower bodies are selected based on different flow rates and supporting equipment requirements. Too small affects the output, and too large is difficult to clean.

[0026] In specific implementation, the tower plate 3 is oval, with a length of 30 cm and a width of 25 cm. In some embodiments, the length or width of each tower plate 3 is not necessarily required to be consistent, and the size of the tower plate 3 can be customized according to different glue coating requirements. This flexibility can optimize the glue coating process and improve the gel quality and production efficiency. The tower plate can also be tilted to make the flow smoother.

[0027] In specific implementation, the length of the liquid guiding groove 4 runs through the length of the tray 3; the width is 20 cm. The liquid guiding groove with a length running through helps to improve the flow characteristics of the liquid on the tray, ensuring that the liquid can flow along the entire tray instead of just concentrating in a certain area, thereby increasing the contact area between the sol and the tray, ensuring sufficient mixing of the catalyst and the sol, and at the same time reducing sol residue, which is convenient for cleaning and maintenance.

[0028] In specific implementation, the diameter of the liquid passing hole 5 is 1 cm. A diameter of 1 cm helps to ensure that the liquid can be evenly distributed on the tray, avoiding blockage problems caused by local accumulation or uneven distribution.

[0029] In specific implementation, the tray 3 has 5 layers, and the distance between the trays 3 is 3 cm. The design of multiple trays can achieve multi-layer alternating flow of the sol, thereby changing the speed and direction of the sol, helping to break droplets, increasing the surface area of the liquid, effectively improving the liquid distribution, and enhancing the mixing uniformity.

[0030] In specific implementation, the glue spraying nozzle is detachably connected to the sol discharging pipeline, and a pump is connected to the pipeline. The pump on the pipeline can transport the sol into the glue spraying nozzle to apply glue to the substrate. And the glue spraying nozzle and the pipeline are detachably connected. In this way, if the glue spraying nozzle is blocked, it can be removed, cleaned, and replaced with a new one, which does not affect continuous production and has a high production efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the technical solutions. Those of ordinary skill in the art should understand that any modifications or equivalent replacements made to the technical solutions of the present invention without departing from the purpose and scope of the present technical solution shall be covered by the scope of the claims of the present invention.
