Nowadays, when using adhesive storage tanks to store adhesives, nitrogen gas can be introduced into the tank to balance the internal pressure and expel the oxygen in the tank, which is convenient for the preservation of adhesives. However, the oxygen is unevenly distributed inside the tank, and when nitrogen gas is introduced, the fumes cannot be quickly discharged through the fixed gas inlet, and a large amount of nitrogen is consumed. Utility Model Content

[0022] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0023] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a pressure-balanced adhesive storage tank.

[0024] Example 1

[0025] For easier understanding, please refer to Figures 1 to 4 This utility model provides an embodiment of a pressure-balanced adhesive storage tank, comprising a tank body 1, a cap 101 welded and fixed to the top of the tank body 1, and an air inlet mechanism provided at the bottom of the cap 101; the air inlet mechanism includes a connecting pipe 7, several branch pipes 8, a bracket 9, several first mounting shells 10, a solenoid valve 11, a nozzle 12, several second mounting shells 13, and an oxygen concentration sensor 14; the connecting pipe 7 is fixedly installed at the center of the bottom of the cap 101, the bracket 9 is fixedly installed on the inner ring of the bottom of the cap 101, several branch pipes 8 are fixedly installed at the bottom of the connecting pipe 7, several first mounting shells 10 and second mounting shells 13 are fixedly installed on the bracket 9, the solenoid valve 11 is fixedly installed on the inner wall of the first mounting shell 10, the nozzle 12 is fixedly installed at the bottom of the first mounting shell 10, the nozzle 12 is connected to one end of the outlet of the solenoid valve 11, the branch pipes 8 are connected to one end of the inlet of the corresponding solenoid valve 11, and the oxygen concentration sensor 14 is fixedly installed on the inner wall of the second mounting shell 13.

[0026] It should be noted that by setting up an air intake mechanism, nitrogen enters several branch pipes 8 through connecting pipe 7 and is sprayed out through nozzle 12, inputting nitrogen into the tank 1. By setting multiple oxygen concentration sensors 14 at the bottom of the support 9, oxygen at various locations above the tank 1 can be detected. The solenoid valve 11 controls the flow rate of each nozzle 12. The flow rate of nitrogen output from each nozzle 12 is adjusted according to the oxygen concentration, which can quickly discharge oxygen and reduce nitrogen consumption. The solenoid valve 11 can be an adjustable solenoid valve, which controls the channel area by changing the valve core position and adjusts the airflow.

[0027] In this example, the oxygen concentration sensor 14 can be an InPro 6800G / 12 / 120 / Ka electrochemical oxygen sensor, which uses the chemical reaction of oxygen to generate a current proportional to the oxygen concentration to detect the oxygen concentration inside the tank 1.

[0028] In some embodiments, such as Figure 2As shown, an installation frame 2 is fixedly installed on the top of the end cap 101, and a nitrogen sealing valve 3 is fixedly installed on the inner wall of the installation frame 2. The top of the connecting pipe 7 extends to the top of the end cap 101, and the top of the connecting pipe 7 is connected to one end of the outlet of the nitrogen sealing valve 3. One end of the inlet of the nitrogen sealing valve 3 extends to the outside of one side of the installation frame 2, and a gas supply pipe 4 is fixedly installed on one end of the inlet of the nitrogen sealing valve 3.

[0029] It should be noted that the nitrogen sealing valve 3 can be a nitrogen self-regulating valve of model ZZDQ-16B DN40, which consists of two main parts: a quick-release valve and a self-regulating micro-pressure regulating valve, and can control the delivery of nitrogen.

[0030] In this example, one end of the gas supply pipe 4 is connected to an external gas cylinder containing nitrogen.

[0031] In some embodiments, such as Figure 2 As shown, a pressure transmitter 6 and a breather valve 5 are fixedly installed on the top of the end cap 101, and a discharge port 15 is fixedly installed on one side of the outer wall of the tank body 1.

[0032] It should be noted that the pressure transmitter 6 is used to detect the gas pressure inside the tank 1. The breather valve 5 can be a one-way breather valve from the prior art. When the pressure of the medium inside the tank 1 is within the control operating pressure range of the breather valve 5, the breather valve 5 does not work, maintaining the airtightness of the tank 1. When nitrogen is added to the tank 1, the pressure in the upper gas space of the tank 1 increases. When the pressure reaches the positive operating pressure of the breather valve 5, the pressure valve in the breather valve 5 is opened, and oxygen escapes from the exhalation outlet of the breather valve 5, balancing the gas pressure inside the tank 1.

[0033] In this example, the outlet 15 is sealed when storing adhesive, and an electric valve can be installed to seal it.

[0034] In this example, a feed inlet 17 is welded and fixed on the end cap 101. The feed inlet 17 is used to fill the adhesive into the tank 1. The feed inlet 17 is sealed by a ball valve as in the prior art.

[0035] Example 2

[0036] In some embodiments, such as Figure 4 As shown, several baffles 16 are fixedly installed at the bottom of the bracket 9 by screws, and the nozzles 12 are located inside the corresponding baffles 16.

[0037] It should be noted that the baffle 16 is provided with several holes, which can block the nitrogen gas sprayed from the nozzle 12, so that the nitrogen gas can be sprayed out more gently. In addition, by setting several branch pipes 8 to increase the nitrogen gas addition range, it is easier to fill the tank 1 with nitrogen gas.

[0038] The pressure transmitter 6 in this utility model is a known component and will not be described in detail here.

[0039] Working principle: When balancing the internal pressure of tank 1, nitrogen sealing valve 3 is opened to allow nitrogen from the nitrogen tank to enter tank 1, increasing the internal pressure of tank 1. Pressure transmitter 6 monitors the internal pressure of tank 1 in real time. When the pressure reaches the set value, breather valve 5 is opened to discharge oxygen. After a period of time, nitrogen sealing valve 3 is closed to stop the gas supply, thereby maintaining the internal pressure balance of tank 1.

[0040] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
