Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to a visual flow rate adjustment device for nitrogen gas inlet in adhesive production. Background Technology

[0002] The adhesive preparation technology primarily involves the processing of raw materials in the manufacture of medical tubing. Nitrogen gas is introduced during the tubing preparation process primarily because nitrogen is inert and can create an oxygen-free or low-oxygen environment, thus providing protection. The materials used in medical tubing are easily oxidized during high temperatures or chemical reactions, leading to performance degradation. Nitrogen, as an inert gas, effectively isolates oxygen and prevents material oxidation. Furthermore, nitrogen can displace oxygen and other gases that may contain microorganisms from the air, reducing the likelihood of microbial growth and maintaining a sterile environment during the preparation process. Therefore, introducing nitrogen into the adhesive preparation tank is essential.

[0003] Currently, existing technologies include a nitrogen connection pipe installed on the glue-making tank, through which nitrogen gas is introduced. However, the flow rate of the nitrogen cannot be reliably observed visually. If the nitrogen flow rate is too high, it can easily carry raw materials out of the glue-making tank; if the nitrogen flow rate is too low, it cannot effectively prevent oxidation or maintain a sterile environment.

[0004] Therefore, there is an urgent need to propose a visual flow adjustment device for nitrogen gas in the glue-making process that is simple in structure, intuitive, and reliable. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a visual flow rate adjustment device for nitrogen gas in the glue-making process. The technical solution adopted by this utility model is as follows:

[0006] A visible flow rate adjustment device for nitrogen gas supply in adhesive preparation is connected to an adhesive preparation tank and supplies nitrogen gas to the tank. It includes, from top to bottom, a sealingly connected adhesive preparation tank inlet pipe, a transparent outer support pipe, a lower connecting flange pipe, and an inlet valve; a notch groove on one side of the transparent outer support pipe; a transparent inner pipe embedded within the transparent outer support pipe and positioned at the notch groove; a mesh plate positioned between the adhesive preparation tank inlet pipe and the transparent outer support pipe; a lower mesh plate positioned between the transparent outer support pipe and the lower connecting flange pipe; and a flow ball positioned within the transparent inner pipe and between the mesh plate and the lower mesh plate. The mesh plate and the lower mesh plate have several mesh openings. The inlet valve is connected to external nitrogen gas. The transparent inner pipe and the transparent outer support pipe are sealed together.

[0007] Furthermore, the notch groove is arranged along the periphery of the outer support tube of the transparent tube.

[0008] Furthermore, the arc circumference of the notch is less than half the circumference of the outer support tube of the transparent tube.

[0009] Furthermore, an inner tube mounting groove is provided on the inner side of the outer support tube of the transparent tube; the transparent inner tube is placed in the inner tube mounting groove; the inner tube mounting groove is connected to the notch groove.

[0010] Furthermore, a first sealing ring is provided between the upper part of the inner wall of the inner tube mounting groove and the transparent inner tube, and between the lower part of the inner wall of the inner tube mounting groove and the transparent inner tube.

[0011] Furthermore, the outer support tube of the transparent tube is provided with an upper flange and a lower flange; the mesh plate is placed between the upper flange and the air inlet pipe of the glue-making tank; the lower mesh plate is placed between the lower flange and the lower connecting flange tube.

[0012] Furthermore, a second sealing ring is provided between the upper flange and the air inlet pipe of the glue-making tank, and between the lower flange and the lower connecting flange pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model has a notch and an inner tube mounting groove on the outer support tube of the transparent tube, and the transparent inner tube is installed in the inner tube mounting groove. When the air inlet pipe of the glue tank, the outer support tube of the transparent tube and the lower connecting flange pipe are connected, it is not subjected to the extrusion force of the flange connection, thus ensuring reliable installation. In addition, this utility model allows for visual observation of the flow rate through the transparent inner tube and the flow ball.

[0015] (2) In this utility model, the mesh plate is placed between the upper flange and the air inlet pipe of the glue tank, and the lower mesh plate is placed between the lower flange and the lower connecting flange pipe, so as to facilitate the convenient installation of the mesh plate and the lower mesh plate.

[0016] (3) The present invention achieves a reliable sealing connection by setting a first sealing ring and a second sealing ring.

[0017] (4) This utility model supports the transparent inner tube by using an outer support tube (the part without the notch or groove) to ensure that it is reliable under pressure.

[0018] In summary, this utility model has the advantages of simple structure, intuitiveness and reliability, and has high practical and promotional value in the field of adhesive technology. Attached Figure Description
