Description

Technical Field

[0001] The utility model relates to the field of filtering supporting equipment, in particular to a negative pressure structure for filtering ink. Background Art

[0002] In modern industrial production, ink is often used to print and dye various products. In order to ensure the quality of printing and dyeing during the application process, ink filtering equipment is needed to filter the ink. At the same time, in order to avoid excessive bubbles in the ink, some equipment uses negative pressure extraction to drive the ink flow and complete the filtering task. In this process, a negative pressure structure for filtering the ink is needed;

[0003] When the existing negative pressure structure for filtering ink is used, it generally adopts a vacuum pump and other equipment to directly extract the air in the ink tank. However, in actual operation, the amount of ink used in many production processes is not much, so the volume of the ink tank is not large. Directly using a larger equipment such as a vacuum pump will not only occupy the production space of the workshop, but the vibration and sound generated will also affect the production environment.

[0006] A turbine is arranged inside the airflow passage bin, and an impeller is installed on one side of the turbine;

[0007] The airflow passage bin is connected to an airflow discharge pipe on one side away from the exhaust pipe, and the outer side of the airflow discharge pipe is evenly provided with limited position passing holes, the inner side of the airflow discharge pipe is provided with a threaded connection cylinder, and the outer side of the threaded connection cylinder is evenly provided with limited position grooves, and the outer side of the threaded connection cylinder away from one end of the airflow discharge pipe is sleeved with a cylindrical silencer, and one end of the outer side wall of the cylindrical silencer is provided with an exhaust port;

[0009] As a further solution of the utility model: a mounting angle iron is installed at one end of the airflow passage bin away from the high-pressure airflow passage pipe, and a mounting hole is opened on the mounting angle iron.

[0011] As a further solution of the utility model: the threaded connection tube is threadedly connected to the airflow discharge pipe, and the threaded connection tube is rotationally connected to the cylinder-type silencer.

[0012] As a further solution of the utility model: the elastic mechanism includes a movable block, which is arranged inside the fitting groove, and a spring is connected between the movable block and the cylindrical silencer, and a limiting rod is installed on the side of the movable block close to the air flow through the bin, and the limiting rod passes through the limiting hole and extends to the inside of the limiting groove.

[0013] As a further solution of the utility model: the cross-sectional shape of the movable block is "T"-shaped, and the movable block and the fitting groove form a sliding structure.

[0014] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0015] (1) By directly connecting a small compressed air tank with a high-pressure air flow through a pipe, the compressed air is sprayed toward the impeller to drive the turbine to rotate, so that the turbine can rotate and the air in the tank can be extracted through an exhaust pipe connected to the ink tank, thereby completing the task of ink flow filtration. At the same time, a cylindrical silencer is arranged on the threaded connection cylinder, so that the structure does not need to use a relatively large electrical equipment to complete the air extraction task, which is more suitable for some production processes that do not require too much ink, reducing the excessive workshop operation space occupied at this stage, and reducing the vibration and sound impact of large equipment on the workshop;

[0017] (3) The limiting rod passes through the limiting hole and is inserted into the limiting groove, so that the limiting rod can not only complete the task of limiting and fixing the cylindrical silencer, but also limit the relative rotation between the airflow discharge pipe and the threaded connection cylinder, thereby further ensuring the stability of the installation between the airflow discharge pipe and the threaded connection cylinder, and avoiding the loosening of the cylindrical silencer caused by airflow during use.

[0030] See also Figure 1-Figure 4 As shown, the utility model is a negative pressure structure for filtering ink, comprising an airflow chamber 1, one side of the airflow chamber 1 is connected to an exhaust pipe 3, and one end of the airflow chamber 1 is connected to a high-pressure airflow pipe 4, and an extension pipe can be added to the end of the high-pressure airflow pipe 4 away from the airflow chamber 1, so that it is convenient for the staff to place the small high-pressure gas tank at a suitable position and spray the high-pressure airflow through the extension pipe and the high-pressure airflow pipe 4;

[0031] like Figure 1 As shown, a mounting angle iron 2 is installed at one end of the airflow passage bin 1 away from the high-pressure airflow passage tube 4, and a mounting hole is opened on the mounting angle iron 2. The mounting angle iron 2 and the airflow passage bin 1 can be mounted by welding, and the mounting angle iron 2 can be mounted on the ink tank by means of mounting methods such as bolts;

[0032] like Figure 2 As shown, a turbine 5 is arranged inside the airflow chamber 1, and an impeller 6 is installed on one side of the turbine 5. The turbine 5 is rotatably connected to the airflow chamber 1, and the turbine 5 and the impeller 6 are made in an integrated manner, so as to ensure the connection strength between the turbine 5 and the impeller 6 during use. The air port of the high-pressure airflow pipe 4 close to the airflow chamber 1 is aligned with the blade part of the impeller 6, so that the airflow discharged from the high-pressure airflow pipe 4 can drive the impeller 6 and the turbine 5 to rotate relative to the airflow chamber 1, so that the turbine 5 can extract air from the ink tank through the exhaust pipe 3;

[0033] like Figure 2 and Figure 3As shown, the side of the airflow passage chamber 1 away from the exhaust pipe 3 is connected with an airflow discharge pipe 7, and the outer side of the airflow discharge pipe 7 is evenly provided with limited through holes 8, the inner side of the airflow discharge pipe 7 is provided with a threaded connection tube 9, and the outer side of the threaded connection tube 9 is evenly provided with limited grooves 10, and the outer side of the threaded connection tube 9 away from the end of the airflow discharge pipe 7 is sleeved with a cylindrical silencer 11, and one end of the outer wall of the cylindrical silencer 11 is provided with an exhaust port 12, so that during use, the air discharged from the high-pressure airflow through the pipe 4 in the airflow passage chamber 1 and the air extracted from the ink tank through the exhaust pipe 3 are finally discharged from the exhaust port 12 on the cylindrical silencer 11 through the airflow discharge pipe 7 and the threaded connection tube 9. In this process, the exhaust port 12 can reduce the sound of the airflow discharge, thereby further reducing the impact on the surrounding environment of the workshop;

[0034] Example 2

[0035] like Figure 2 As shown, the threaded connection tube 9 is threadedly connected to the airflow discharge pipe 7, and the threaded connection tube 9 is rotatably connected to the cylindrical silencer 11, so that the staff can install the threaded connection tube 9 and the cylindrical silencer 11 on the airflow discharge pipe 7 by twisting. At the same time, after the installation is completed, the direction of the exhaust port 12 can be adjusted by rotating the cylindrical silencer 11 relative to the threaded connection tube 9, so that the direction of the exhaust port 12 is more suitable for the direction of the exhaust gas, further reducing the impact on the workshop;

[0036] like Figure 2 and Figure 3 As shown, a fitting groove 13 is provided at one end of the cylindrical silencer 11 near the threaded connection cylinder 9, and an elastic mechanism for fixing the cylindrical silencer 11 is provided inside the fitting groove 13, and the elastic mechanism includes a movable block 14, which is arranged inside the fitting groove 13, and a spring 15 is connected between the movable block 14 and the cylindrical silencer 11, and a limiting rod 16 is installed on the side of the movable block 14 near the airflow through the bin 1, and the limiting rod 16 extends through the limiting through hole 8 to the inside of the limiting groove 10, and the cross-sectional shape of the movable block 14 is "T"-shaped, and the movable block 14 and the fitting groove 13 form a sliding structure, so that Before the staff rotates the cylindrical silencer 11 relative to the threaded connection tube 9 to adjust the direction of the exhaust port 12, they can release the limiting fixation of the threaded connection tube 9 and the exhaust port 12 by pulling the limiting rod 16 out of the corresponding limiting hole 8 and the limiting groove 10. After the adjustment is completed, the spring 15 drives the limiting rod 16 to be reinserted into the corresponding limiting hole 8 and the limiting groove 10, which can simultaneously limit the rotation between the airflow discharge pipe 7, the threaded connection tube 9 and the cylindrical silencer 11, so that the cylindrical silencer 11 can be fixed at the adjusted angle, and at the same time, the threaded connection tube 9 and the airflow discharge pipe 7 are prone to loosening.

[0037] The working principle of the utility model is as follows: the end of the air extraction pipe 3 away from the air flow through the bin 1 is connected to the ink tank, and a valve can be provided on the air extraction pipe 3 to facilitate sealing the ink tank after the air extraction is completed or when not in use, and the high-pressure air flow through the pipe 4 is connected to the small high-pressure gas tank through the extension pipe, and the threaded connection tube 9 and the limiting rod 16 are respectively held and the limiting rod 16 is pulled in the direction away from the threaded connection tube 9, and the above state is maintained by screwing the threaded connection tube 9 into the air flow discharge pipe 7. After being fully tightened, the limiting hole 8 and the corresponding limiting groove 10 are The cylinder type silencer 11 is in the mutually aligned rotation, and the above state is maintained to rotate on the threaded connection cylinder 9 until the exhaust port 12 is aligned with a more suitable direction for exhaust, and then the limiting rod 16 is loosened, and the spring 15 drives the limiting rod 16 to be inserted into the corresponding limiting through hole 8 and the limiting groove 10, so that the rotation between the airflow discharge pipe 7, the threaded connection cylinder 9 and the cylinder type silencer 11 is completely restricted, thereby preventing the airflow discharge pipe 7 and the threaded connection cylinder 9 from loosening, and at the same time fixing the cylinder type silencer 11 at the adjusted angle;

[0038] When it is necessary to evacuate the ink tank to filter the ink, open the small high-pressure gas tank so that the high-pressure airflow is ejected toward the impeller 6 through the tube 4, thereby driving the turbine 5 and the impeller 6 to rotate. The turbine 5 can drive the air to be extracted from the ink tank through the exhaust pipe 3, so that a negative pressure is generated in the ink tank. At this time, the ink in the ink storage device connected to the ink tank can enter the ink tank under the action of air pressure, and the filtering part between the ink tank and the ink storage device can complete the filtering task for the ink. The air entering the airflow passes through the internal air of the bin 1 and then enters the exhaust port 12 through the airflow discharge pipe 7 and the threaded connection tube 9, and is finally discharged through the exhaust port 12. In this process, the cylindrical silencer 11 can slow down and reduce the noise of the airflow, thereby further reducing the impact on the workshop.
