The lower end of the odor purifier 1 is fixed with a vertical pipe 22, the lower end of the vertical pipe 22 is fixed with a horizontal pipe 21, the middle position of the lower end of the horizontal pipe 21 is fixed with a connecting pipe 24, and the two ends of the horizontal pipe 21 are slidably connected with folded pipes 23.

[0021] By adopting the above technical solution, firstly, the connecting pipe 24 at the lower end of the horizontal pipe 21 is connected to the air outlet of the equipment in the middle section of the sewage treatment. Then, according to the sewage treatment equipment on both sides of the middle section of the sewage treatment, the folded pipe 23 is moved in the horizontal pipe 21 until the folded pipe 23 corresponds to the air outlet of the sewage treatment equipment on both sides. Then, the folded pipe 23 can be connected to the air outlet of the sewage treatment equipment. The sewage treatment odor enters the horizontal pipe 21 through the folded pipe 23 and the connecting pipe 24, and then enters the odor purifier 1 through the vertical pipe 22 for odor treatment. By setting the docking component 2, the distance between the connecting pipe 24 and the folded pipe 23 on the lower side of the odor purifier 1 can be adjusted according to the distance between each process section of the sewage treatment, so as to facilitate the docking of the odor purifier 1 with each process section of the sewage treatment.

[0022] Specifically, the docking assembly 2 also includes a fixing plate 25, a fixing seat 26, a rectangular rod 27, a fixing bolt 28, an auxiliary assembly 29, and a side plate 210.

The sealing gasket 294 is fixed on the inner wall of the annular seat 291 to make the folded tube 23 fit more closely with the horizontal tube 21 and the sealing performance is better. At the same time, when the folded tube 23 retracts into the horizontal tube 21, the conical body 292 can clean the impurities attached to the surface of the folded tube 23. Several support rods 293 are fixed between the conical body 292 and the annular seat 291 to make the connection between the conical body 292 and the annular seat 291 more secure.

[0026] Specifically, connecting flanges are fixed on both the folded pipe 23 and the connecting pipe 24. The side of the folded pipe 23 is tangent to the inner wall of the horizontal pipe 21. The horizontal pipe 21, the vertical pipe 22 and the connecting pipe 24 are a welded integral structure.

[0027] By adopting the above technical solution, the connection flange facilitates the connection of the folded pipe 23 and the connecting pipe 24 to the sewage treatment equipment. The folded pipe 23 fits more closely with the horizontal pipe 21. The horizontal pipe 21, the vertical pipe 22 and the connecting pipe 24 are welded as a whole, making them more robust and durable.

[0029] By adopting the above technical solution, the rectangular rod 27 can slide in the fixed seat 26, and the lower end of the fixing bolt 28 is fixed with an anti-slip pad to play an anti-slip role, thereby making the fixing bolt 28 more effective in limiting the rectangular rod 27.

[0030] Specifically, the inner side of the conical body 292 is in close contact with the outer side of the folded tube 23, the sealing gasket 294 is bonded to the annular seat 291 with glue, and the support rod 293 is spot welded to the annular seat 291.

[0031] By adopting the above technical solution, the inner side of the cone 292 and the outer side of the folded tube 23 are more closely attached, and the adhesive bonding makes the sealing gasket 294 more secure.

[0032] In this embodiment, when using the buried sewage odor treatment equipment, the device is installed in a suitable position. First, the connecting pipe 24 at the lower end of the horizontal pipe 21 is connected to the air outlet of the equipment in the middle section of the sewage treatment. Then, according to the sewage treatment equipment on both sides of the middle section of the sewage treatment, the folded pipe 23 is moved in the horizontal pipe 21 until the folded pipe 23 corresponds to the air outlet of the sewage treatment equipment on both sides. Then, the folded pipe 23 can be connected to the air outlet of the sewage treatment equipment. The sewage odor enters the horizontal pipe 21 through the folded pipe 23 and the connecting pipe 24, and then enters the odor purifier 1 through the vertical pipe 22 for odor treatment. By setting the docking component 2, the distance between the connecting pipe 24 and the folded pipe 23 on the lower side of the odor purifier 1 can be adjusted according to the distance between the various process sections of the sewage treatment, so as to facilitate the docking of the odor purifier 1 with the various process sections of the sewage treatment. When moving the folded pipe 23, the upper side of the folded pipe 23 is fixed. The rectangular rod 27 at one end of the plate 25 slides in the fixed seat 26. After the folded tube 23 moves to the appropriate position, the fixing bolt 28 can be tightened to move downward in the fixed seat 26, thereby making the fixing bolt 28 press against the rectangular rod 27, achieving the effect of limiting and fixing the rectangular rod 27 and the folded tube 23. By setting the rectangular rod 27, the folded tube 23 can be limited and fixed, avoiding displacement and shaking of the folded tube 23 during use. By setting the auxiliary component 29, the folded tube 23 slides in the annular seat 291 when it moves. The sealing gasket 294 is fixed on the inner wall of the annular seat 291 to make the folded tube 23 fit better with the horizontal tube 21 and the sealing performance is better. At the same time, when the folded tube 23 retracts into the horizontal tube 21, the conical body 292 can clean the impurities attached to the surface of the folded tube 23. Several support rods 293 are fixed between the conical body 292 and the annular seat 291 to make the conical body 292 and the annular seat 291 more secure.

[0033] Example 2 The difference between this embodiment and embodiment 1 is that the loading assembly 3 includes a top cover 31, mounting bolts 32, a loading cylinder 33, a honeycomb plate 34, and vent holes 35. The loading cylinder 33 is provided on the upper side inside the odor purifier 1. Activated carbon filler 6 and adsorption filler 7 are both placed in the loading cylinder 33. A honeycomb plate 34 is provided between the activated carbon filler 6 and the adsorption filler 7. Several vent holes 35 are opened at the lower end of the loading cylinder 33. The top cover 31 is provided at the upper end of the odor purifier 1. The top cover 31 is connected to the odor purifier 1 by mounting bolts 32. The end of the discharge pipe 5 away from the drain cap 4 is fixed to the top cover 31.

[0034] By adopting the above technical solution, an appropriate amount of activated carbon filler 6 is put into the loading cylinder 33, and then the honeycomb plate 34 is placed on top of the activated carbon filler 6 inside the loading cylinder 33. Then, an appropriate amount of adsorption filler 7 is put into the top of the honeycomb plate 34. After that, the loading cylinder 33 can be placed into the odor purifier 1. Finally, the top cover 31 is installed and fixed to the odor purifier 1 by the mounting bolts 32. The odor can enter the loading cylinder 33 through the vent 35, and after being filtered by the activated carbon filler 6 and the adsorption filler 7, it is discharged through the discharge pipe 5, thereby achieving the effect of odor treatment. The loading assembly 3 facilitates the replacement of the activated carbon filler 6 and the adsorption filler 7.

[0035] Specifically, the loading assembly 3 also includes an annular plate 36, a lead screw 37, a rotary handle 38, a guide rod 39, and a positioning plate 310. The annular plate 36 is provided inside the odor purifier 1 at a position corresponding to the loading cylinder 33. The lead screw 37 is rotatably connected to one side of the lower end of the annular plate 36, and the rotary handle 38 is fixed to the lower end of the lead screw 37. The guide rod 39 is fixed to the other side of the lower end of the annular plate 36. The positioning plates 310 are fixed at both ends of the odor purifier 1 at positions corresponding to the annular plate 36.

[0036] By adopting the above technical solution, when it is necessary to replace the activated carbon packing 6 and the adsorption packing 7, the top cover 31 is disassembled, and then the screw 37 is rotated by the handle 38. The screw 37 rotates and pushes the annular plate 36 upward. The guide rod 39 slides on one side of the lower end of the odor purifier 1. The upward movement of the annular plate 36 can push the loading cylinder 33 out of the odor purifier 1. Then the loading cylinder 33 can be taken out of the odor purifier 1, so that the activated carbon packing 6 and the adsorption packing 7 in the loading cylinder 33 can be tilted and replaced. The positioning plates 310 at both ends inside the odor purifier 1 can position and fix the annular plate 36. By setting the annular plate 36, the installation of the loading cylinder 33 can be supported, and at the same time, it is convenient to push the loading cylinder 33 out of the odor purifier 1 and take the loading cylinder 33 out of the odor purifier 1.

[0037] Specifically, the lower end of the odor purifier 1 has threaded holes and sliding holes corresponding to the lead screw 37 and guide rod 39 on both sides. After the loading cylinder 33 is installed into the odor purifier 1, the side of the loading cylinder 33 is in close contact with the inner wall of the odor purifier 1.

[0038] By adopting the above technical solution, the lead screw 37 and the guide rod 39 can move on both sides of the lower end of the odor purifier 1, and after the loading cylinder 33 is installed into the odor purifier 1, the side of the loading cylinder 33 fits more closely with the inner wall of the odor purifier 1.

[0039] In this embodiment, a suitable amount of activated carbon filler 6 is added to the loading cylinder 33. Then, the honeycomb plate 34 is placed on top of the activated carbon filler 6 inside the loading cylinder 33. Next, a suitable amount of adsorption filler 7 is added to the top of the honeycomb plate 34. The loading cylinder 33 can then be placed into the odor purifier 1. Finally, the top cover 31 is fixed to the odor purifier 1 using mounting bolts 32. Odors can enter the loading cylinder 33 through the vent 35, and after being filtered by the activated carbon filler 6 and adsorption filler 7, are discharged through the discharge pipe 5, achieving the effect of odor control. The loading assembly 3 facilitates the replacement of the activated carbon filler 6 and adsorption filler 7. 7. When replacing, remove the top cover 31, then rotate the screw 37 by the handle 38. The screw 37 rotates and pushes the annular plate 36 upward. The guide rod 39 slides on one side of the lower end of the odor purifier 1. The upward movement of the annular plate 36 can push the loading cylinder 33 out of the odor purifier 1. Then the loading cylinder 33 can be taken out of the odor purifier 1, so that the activated carbon packing 6 and adsorption packing 7 in the loading cylinder 33 can be tilted and replaced. The positioning plates 310 at both ends inside the odor purifier 1 can position and fix the annular plate 36. By setting the annular plate 36, the installation of the loading cylinder 33 can be supported, and at the same time, it is convenient to push the loading cylinder 33 out of the odor purifier 1 and take the loading cylinder 33 out of the odor purifier 1.

[0040] The structure and working principle of the odor purifier 1, drainage cap 4, discharge pipe 5, activated carbon packing 6 and adsorption packing 7 in this utility model have been disclosed in the buried sewage odor treatment equipment disclosed in Chinese patent application number 2015207888930.

[0041] The working principle and usage process of this utility model: When using the buried sewage odor treatment equipment, install the device in a suitable position. First, connect the connecting pipe 24 at the lower end of the horizontal pipe 21 to the air outlet of the equipment in the middle section of the sewage treatment. Then, according to the sewage treatment equipment on both sides of the middle section of the sewage treatment, pull the folded pipe 23 to move in the horizontal pipe 21 until the folded pipe 23 corresponds to the air outlet of the sewage treatment equipment on both sides. Then, connect the folded pipe 23 to the air outlet of the sewage treatment equipment. The sewage odor enters the horizontal pipe 21 through the folded pipe 23 and the connecting pipe 24, and then enters the odor purifier 1 through the vertical pipe 22 for odor treatment. By setting the docking component 2, the connecting pipe 24 on the lower side of the odor purifier 1 can be adjusted according to the distance between the various process sections of the sewage treatment. The distance between the 4 and the bend tube 23 facilitates the connection between the odor purifier 1 and the various process sections of the sewage treatment. When the bend tube 23 is moved, the rectangular rod 27 at one end of the fixing plate 25 on the upper side of the bend tube 23 slides in the fixing seat 26. After the bend tube 23 is moved to the appropriate position, the fixing bolt 28 can be tightened to move downward in the fixing seat 26, thereby making the fixing bolt 28 press against the rectangular rod 27, achieving the effect of limiting and fixing the rectangular rod 27 and the bend tube 23. By setting the rectangular rod 27, the bend tube 23 can be limited and fixed, avoiding displacement and shaking of the bend tube 23 during use. By setting the auxiliary component 29, the bend tube 23 slides in the annular seat 291 when it moves. The sealing gasket 294 is fixed on the inner wall of the annular seat 291 to prevent the bend tube 23 from moving. The conical body 292 provides a better seal between the conical body 23 and the horizontal tube 21, and when the conical body 23 retracts into the horizontal tube 21, it can clean impurities adhering to the surface of the conical body 23. Several support rods 293 are fixed between the conical body 292 and the annular seat 291 to make the relationship between the conical body 292 and the annular seat 291 more secure. An appropriate amount of activated carbon filler 6 is put into the loading cylinder 33, and then the honeycomb plate 34 is placed on top of the activated carbon filler 6 inside the loading cylinder 33. An appropriate amount of adsorption filler 7 is then put into the top of the honeycomb plate 34. The loading cylinder 33 can then be placed into the odor purifier 1. Finally, the top cover 31 is installed and fixed to the odor purifier 1 with the mounting bolts 32. Odors can enter the loading cylinder 33 through the vent 35, thereby being purified by the activated carbon filler 292. After filtration, the activated carbon packing 6 and adsorption packing 7 are discharged through the discharge pipe 5, achieving the effect of odor control. The loading assembly 3 facilitates the replacement of the activated carbon packing 6 and adsorption packing 7. When replacement is needed, the top cover 31 is removed, and then the screw 37 is rotated via the handle 38. The screw 37 rotates, pushing the annular plate 36 upwards. The guide rod 39 slides on one side of the lower end of the odor purifier 1. The upward movement of the annular plate 36 pushes the loading cylinder 33 out of the odor purifier 1, allowing the loading cylinder 33 to be removed. This allows the activated carbon packing 6 and adsorption packing 7 inside the loading cylinder 33 to be emptied and replaced. The positioning plates 310 at both ends inside the odor purifier 1 can position and fix the annular plate 36.The annular plate 36 and similar components provide support for the loading cylinder 33, and also facilitate the removal of the loading cylinder 33 from the odor purifier 1.
