[0030] A feed hopper 105 is fixedly connected to one side of the top of the sealing cover 104. A fixing frame 106 is fixedly connected to the center of the top of the sealing cover 104. One side of the fixing frame 106 is fixedly connected to the first drive motor 107.

One side of the drive wheel 108 is meshed with the first driven wheel 109. The bottom end of the first driven wheel 109 is fixedly connected to the stirring frame 110. The drive wheel 108 is driven to rotate by the first drive motor 107.

[0031] A bearing 111 is fixedly connected to the outer side of the top of the stirring frame 110. The outer side of the bearing 111 is fixedly connected to the sealing cover 104. Several stirring blades 112 are symmetrically fixedly connected to the left and right sides of the stirring frame 110. There are four sets of stirring blades 112, and the stirring blades 112 are evenly distributed on both sides of the stirring frame 110. The stability of the stirring frame 110 is improved by setting the bearing 111.

[0032] Threaded rods 113 are fixedly connected to the upper and lower ends of both sides of the mixing frame 110. A cleaning brush 114 is threadedly connected to the outer side of one end of the threaded rod 113. One side of the cleaning brush 114 is in close contact with the mixing chamber 102. A second driven wheel 115 is meshed with the other side of the driving wheel 108. The top end of the second driven wheel 115 is rotatably connected to the fixed frame 106. A roller 116 is fixedly connected to the bottom end of the second driven wheel 115. One end of the roller 116 passes through the mixing frame 110 and is fixedly connected to a threaded rod. The propeller 117, through the meshing between the drive wheel 108 and the first driven wheel 109, drives the mixing frame 110 and the mixing blades 112 to rotate, which can evenly mix the leachate chemical reagents. At the same time, through the meshing between the drive wheel 108 and the second driven wheel 115, the propeller 117 is driven to rotate, which can transport the leachate chemical reagents at the bottom of the mixing chamber 102 to the top, which facilitates repeated mixing of the liquid and makes the leachate chemical reagents more evenly mixed.

[0033] The feeding mechanism 2 includes a base 201. The bottom of the base 201 is fixedly connected to the base plate 101. One side of the base 201 is fixedly connected to the second drive motor 202. The output end of the second drive motor 202 passes through the base 201 and is fixedly connected to a worm gear 203. One end of the worm gear 203 is rotatably connected to the base 201. One side of the worm gear 203 is meshed with a worm wheel 204. A support column 205 is fixedly connected to the center position inside the worm wheel 204. The position of the second drive motor 202 can be limited by setting the base 201.

[0034] The bottom end of the support column 205 is rotatably connected to the base 201, and the top end of the support column 205 passes through the base 201 and is fixedly connected to the filter box 206. A filter screen frame 207 is snapped into one side inside the filter box 206, and a filter screen 208 is snapped into the inside of the filter screen frame 207. A box cover 209 is rotatably connected to the side of the filter box 206 near the filter screen frame 207. A hopper 210 is fixedly connected to both the upper and lower sides of the filter box 206 near the filter screen frame 207. The hopper 210 facilitates the addition of chemical reagents to the leachate.

[0035] A limiting bracket 211 is fixedly connected to the side of the filter box 206 near the cover 209. A limiting cylinder 212 is fixedly connected to one side inside the limiting bracket 211. A spring 213 is installed inside the limiting cylinder 212. A cylinder 214 is fixedly connected to one end of the spring 213. The top of the cylinder 214 passes through the limiting cylinder 212 and is fixedly connected to a button 215. A stop bar 216 is fixedly connected to one side of the cylinder 214. The top of the stop bar 216 is engaged with the cover 209. Pressing the button 215 causes the cylinder 214 to compress the spring 213 and simultaneously causes the stop bar 216 to move downward, thereby releasing the stop bar 216 from limiting the cover 209. This allows the cover 209 to be opened, allowing the filter screen frame 207 inside the filter box 206 to be removed and the filter screen 208 inside to be cleaned.

[0036] Working principle: Before using this type of mixing and stirring device for landfill leachate, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5 As shown, the leachate chemical reagent is first poured into the filter box 206 through the hopper 210. The filter screen 208 removes some particulate matter from the leachate. The filtered leachate chemical reagent then falls into the mixing chamber 102. The first drive motor 107 is then started to drive the drive wheel 108 to rotate. The meshing between the drive wheel 108 and the first driven wheel 109 drives the mixing frame 110 and the mixing blades 112 to rotate, which can mix the leachate chemical reagent evenly. At the same time, the meshing between the drive wheel 108 and the second driven wheel 115 drives the propeller 117 to rotate, which can transport the leachate chemical reagent at the bottom of the mixing chamber 102 to the top, which facilitates repeated mixing of the liquid and makes the leachate chemical reagent more evenly mixed.

[0037] Secondly, when it is necessary to clean the inner wall of the mixing chamber 102, first start the second drive motor 202 to drive the worm 203 to rotate. Utilize the meshing between the worm 203 and the worm wheel 204 to drive the support column 205 and the filter box 206 to rotate, thereby changing the position of the filter box 206, which facilitates the opening of the sealing cover 104. Then, install the cleaning brush at the end of the threaded rod 113, and then close the sealing cover 104. Start the first drive motor 107 to drive the mixing frame and the cleaning brush 114 to rotate, thus completing the cleaning of the inner wall of the mixing chamber 102.

[0038] Finally, when it is necessary to clean the filter screen 208, press the button 215 to compress the cylinder 214 and the spring 213, and at the same time move the stop bar 216 downward. This will release the stop bar 216 from limiting the cover 209, making it easier to open the cover 209 and take out the filter screen frame 207 inside the filter box 206 for cleaning.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
