[0041] Example:

[0042] This embodiment provides a dust collector for an inert gas protection system, which is used to solve the technical problem that a filter cartridge in an inert gas protection system in the prior art is prone to safety accidents when being replaced. The dust collector for an inert gas protection system includes a housing 1, a filter cartridge 2, a main pipe 3, and a branch pipe 4, wherein:

[0043] The shell 1 includes a top cover, a cylinder and a dust storage chamber. The top cover is detachably mounted on the top end of the cylinder, and the dust storage chamber is fixedly mounted on the bottom end of the shell 1.

[0044] There are multiple filter cartridges 2, and the multiple filter cartridges 2 are all installed in the housing 1. Specifically, the multiple filter cartridges 2 can be detachably installed in the cylinder body. In this way, the filter cartridge 2 can be more easily replaced through the detachable filter cartridge 2.

[0045] The main pipe 3 is installed at the top of the shell 1 and is connected to the water source. Optionally, the main pipe 3 is detachably installed at the top of the shell 1. The detachably installed main pipe 3 makes it easier to replace and clean the main pipe 3.

[0046] One end of the branch pipe 4 is installed on the main pipe 3 and connected with the main pipe 3, and the other end extends into the shell 1. The branch pipe 4 is used to spray liquid onto multiple filter cartridges 2. In this way, through the cooperation of the main pipe 3 and the branch pipe 4, the water flow is sprayed onto multiple filter cartridges 2, thereby soaking the filter cartridges 2 and the residual materials on the surface of the filter cartridges 2, so as to avoid the residual materials on the filter cartridges 2 from contacting with oxygen and burning when the filter cartridges 2 are replaced.

[0047] Through the above structure, when the dust collector for the inert gas protection system provided by the utility model is used, when the filter cartridge 2 needs to be replaced, the equipment connected to the front and rear of the dust collector for the inert gas protection system provided by the utility model is first cut off, and then the main pipe 3 and the water source are connected, and the water flow is transported into the branch pipe 4 through the main pipe 3, and then sprayed onto each filter cartridge 2 through the branch pipe 4, so that the filter cartridge 2 and the residual material on its surface are soaked. After soaking the filter cartridge 2 and the residual material on its surface, the shell 1 is opened again, so that the material is prevented from contacting with oxygen and burning. Finally, the filter cartridge 2 in the shell 1 is taken out, and the shell 1 can be closed after replacing the new filter cartridge 2. Therefore, through the setting of the main pipe 3 and the branch pipe 4, the water flow is sprayed onto each filter cartridge 2 to soak it and protect it, so that the dust collector for the inert gas protection system provided by the utility model is not prone to safety accidents when replacing the filter cartridge 2, and the safety is higher.

[0048] An optional implementation of this embodiment is as follows: the main pipe 3 is an annular pipe, which is coaxially arranged with the shell 1, that is, the axis of the annular pipe and the axis of the cylinder are located on the same straight line. The arrangement of the annular pipe makes it easier to adjust the position of the branch pipe 4.

[0049] An optional implementation of this embodiment is as follows: it also includes an atomizing nozzle 5 installed at one end of the branch pipe 4 extending into the shell 1. Through the arrangement of the atomizing nozzle 5, it is more convenient to spray water onto each filter cartridge 2.

In this way, through the multiple evenly arranged branch pipes 4 and atomizing nozzles 5, not only can the water flow be sprayed more evenly onto the multiple filter cartridges 2, but also the spraying efficiency is improved.

[0051] An optional implementation of this embodiment is as follows: it also includes a pneumatic ball valve 6, which is installed on the shell 1 and connected to the ring pipe. The pneumatic ball valve 6 is used to control the on-off of the ring pipe. In this way, the setting of the pneumatic ball valve 6 makes it easier to control the on-off of the water flow.

[0052] An optional implementation of this embodiment is as follows: it also includes an air bag 7 and a blowing pipe 8, wherein:

[0053] The air bag 7 is installed on the housing 1, and the air bag 7 is used to provide an air source.

[0054] There are multiple blow pipes 8, one end of each of which is connected to the air bag 7, and the other end extends into the shell 1 and is located above the multiple filter cartridges 2. Each blow pipe 8 is provided with multiple air holes, and the multiple air holes are arranged in a one-to-one correspondence with the multiple filter cartridges 2 to spray gas into each filter cartridge 2. Through the setting of the blow pipe 8, the airflow is guided to the corresponding filter cartridge 2, and it is sprayed and cleaned. The setting of multiple blow pipes 8 and multiple air holes improves the cleaning efficiency.

[0055] An optional implementation of this embodiment is as follows: it also includes a pressure gauge 9 and a dust concentration detector 10, wherein:

[0056] The pressure gauge 9 is installed on the housing 1 and is used to detect the pressure in the housing 1 . Thus, by setting the pressure gauge 9 , it is convenient to detect the pressure in the housing 1 , thereby detecting whether the filter cartridge 2 is damaged.

[0057] The dust concentration detector 10 is installed on the shell 1. The dust concentration detector 10 is used to detect the dust concentration in the shell 1. In this way, through the setting of the dust concentration detector 10, it is convenient to detect the dust concentration in the shell 1, so as to detect whether the filter cartridge 2 is damaged, thereby further improving the safety of the dust collector for the inert gas protection system provided in the embodiment of the utility model.

[0058] Optionally, a controller is also included, and the pressure gauge 9, the dust concentration detector 10 and the pneumatic ball valve 6 are all electrically connected to the controller through lines. Through the setting of the controller, it is easier to open and close the pneumatic ball valve 6. When the values ​​of the pressure gauge 9 and the dust concentration detection increase significantly, the control component issues an alarm to remind the staff to inspect and replace the filter cartridge 2.

[0059] An optional implementation of this embodiment is as follows: it also includes a liquid level display component 20, which is installed on the shell 1. The liquid level display component 20 is used to display the height of the liquid level in the shell 1. By observing the height of the liquid level in the shell 1, it is determined whether the filter cartridge 2 is completely soaked.

[0060] Optionally, the liquid level display assembly 20 includes a first tube 201, a second tube 202 and a third tube 203, wherein:

[0061] One end of the first tube 201 is connected to the shell 1, specifically, one end of the first tube 201 is connected to the dust storage chamber, and the axis of the first tube 201 is perpendicular to the axis of the shell 1, that is, the first tube 201 is horizontally arranged.

[0062] One end of the second tube 202 is connected to the other end of the first tube 201 , and the axis of the first tube 201 and the axis of the second tube 202 are perpendicular to each other, that is, the second tube 202 is vertically arranged.

[0064] Through the above structure, when the water source is sprayed onto the filter cartridge 2 through the atomizing nozzle 5, the water flow mixed with the material drips along the filter cartridge 2 to the bottom of the shell 1, that is, the dust accumulation chamber. Since the first tube 201 is connected to the dust accumulation chamber, and the second tube 202 is connected to the first tube 201, the liquid enters the second tube 202 through the first tube 201. When it is observed that the liquid level in the second tube 202 reaches a certain height, it means that the filter cartridge 2 in the shell 1 has been completely soaked, and the pneumatic ball valve 6 can be closed to open the top cover to replace the filter cartridge 2.

[0065] An optional implementation of this embodiment is as follows: it also includes a discharge assembly 30, which is used to discharge the material in the shell 1 out of the shell 1 to prevent the material from accumulating in the shell 1 and affecting the use of the liquid level display assembly 20.

[0070] Through the above structure, after all the filter cartridges 2 are disassembled, when the material needs to be discharged from the shell 1, the first valve 301 is first opened and the second valve 303 is closed, so that the material enters the receiving hopper 302 from the dust storage chamber, and then the first valve 301 is closed and the second valve 303 is opened to discharge the material from the receiving hopper 302.

[0071] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
