DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As shown in the figure: Figures 1 to 4

[0024] Embodiment one: the utility model provides a natural gas separation impurity separation device, include: separation tank mechanism 1, including separation tank assembly 11, install on separation tank assembly 11 and preliminary filter assembly 13 of settling assembly 12 of separation tank assembly 11,

[0025] Exhaust mechanism 2, including installation on separation tank assembly 11 exhaust assembly 21, fixedly installed on exhaust assembly 21 fine filter screen 22,

[0026] Settling assembly 12 includes settling box 121, the bottom of the settling box 121 is obliquely fixedly connected with discharge pipe 122, a plurality of baffles 123 are fixedly connected in the inside of the settling box 121 in an up-down staggered manner, and the air outlet 124 is fixedly connected to one side of the settling box 121 away from the discharge pipe 122.

[0027] Specifically, the separation tank assembly 11 includes a tank body 111, the settling box 121 is fixedly connected to the inside of the tank body 111, and one end of the discharge pipe 122 extends to the outside of the tank body 111.

[0028] Specifically, the tank body 111 is fixedly connected with a communication pipe 112, the communication pipe 112 is fixedly connected with an air inlet 113, the settling box 121 and the communication pipe 112 are communicated, and a plurality of support legs 114 are further fixedly connected to the position close to the lower end of the outside of the tank body 111.

[0029] ​Specifically, the preliminary filtering assembly 13 includes a sealing cover 131 threadedly connected outside the communication pipe 112, a plurality of connecting rods 132 fixedly connected to the sealing cover 131, and a filter screen 133 fixedly connected to the plurality of connecting rods 132.

[0030] As can be seen from the above, in use, natural gas is first introduced into the communication pipe 112 through the gas inlet 113, then the natural gas passes through the filter screen 133 in the preliminary filtering assembly 13, and after effectively intercepting part of the impurities, enters the settling tank 121. The up-and-down staggered baffles 123 in the settling tank 121 slow down the flow rate of the gas, providing sufficient settling time for the impurity particles. Under the action of gravity, these particles are finally deposited into the discharge pipe 122, removing most of the larger impurity particles and reducing the burden on the subsequent filter, thereby prolonging the service life of the filter. The user can periodically open the cover on the discharge pipe 122 to clean the settled material. The gas treated by the settling process smoothly enters the inside of the tank body 111 through the gas outlet 124 on the settling tank 121 and continues to be further filtered by the fine filter screen 22 to remove small impurity particles, ensuring the purity of the output gas, and finally being discharged from the exhaust assembly 21. In order to maintain the continuous and efficient operation of the filter screen 133, the user can simply rotate the sealing cover 131 to remove it from the inside of the gas inlet 112 to clean the filter screen 133 as needed, effectively avoiding the occurrence of clogging problems.

[0032] Embodiment Two: This embodiment is basically the same as the previous embodiment, except that the exhaust assembly 21 includes a gas collecting bucket 211 threadedly connected to the bottom of the tank body 111, the bottom of the gas collecting bucket 211 is fixedly communicated with a gas discharge pipe 212, and a handle 213 is fixedly connected to the outside of the gas collecting bucket 211.

[0033] Specifically, the fine filter screen 22 is fixedly connected to the inside of the gas collecting bucket 211.

[0034] As can be seen from the above, through the design of the gas collecting bucket 211, the gas in the tank body 111 is effectively collected and filtered in detail by the fine filter screen 22, and finally discharged from the gas discharge pipe 212. In order to facilitate regular impurity cleaning of the fine filter screen 22, the user can hold the handle 213 and easily rotate it to detach the entire exhaust assembly 21 from the tank body 111, thereby not only improving the efficiency of gas filtration but also greatly simplifying the maintenance process of the fine filter screen.
