DETAILED DESCRIPTION

[0025] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position. Example 1

[0026] A large-scale cooking waste leachate treatment equipment, such as Figure 1-10 As shown, it includes a frame 1, a percolation barrel 2, a mesh plate 3, a cover plate 4, a first slide rail 5, a block 6 and a pushing component 7. The right part of the frame 1 is rotatably provided with the percolation barrel 2, the bottom of the percolation barrel 2 is provided with a liquid outlet, the lower side of the percolation barrel 2 is provided with an oil outlet, the percolation barrel 2 is slidably provided with a mesh plate 3, the upper part of the percolation barrel 2 is rotatably provided with a cover plate 4, two first slide rails 5 are provided on the front and rear sides of the right part of the frame 1, and a block 6 is slidably provided between the two first slide rails 5 on the same side, and the block 6 cooperates with the percolation barrel 2, and the left part of the frame 1 is provided with a pushing component 7.

[0027] When using the device, the staff connects an external water pipe to the liquid outlet at the bottom of the infiltration barrel 2, pours the kitchen waste into the infiltration barrel 2, then rotates the cover 4 to close it, and then filters the liquid in the kitchen waste through the mesh plate 3. Because the density of oil is lower than that of water, the oil will float on the water and be discharged through the oil outlet hole above, while the water will be discharged through the liquid outlet at the bottom of the infiltration barrel 2. While filtering, the staff can drive the mesh plate 3 to move upward by pushing the component 7 to squeeze the liquid in the kitchen waste. When the filtering is completed, the staff pushes the block 6 to slide upward in the first slide rail 5 and no longer jams the infiltration barrel 2. Then, the cover 4 is opened and the infiltration barrel 2 is pushed to dump and pour out the kitchen waste. In this way, the liquid in the kitchen waste can be separated into oil and water.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the pushing assembly 7 includes a fixed frame 71, a strip plate 72, an electric telescopic rod 73, a clamping sleeve 74, a second slide rail 75 and a clamping rod 76. The mesh plate 3 is provided with a fixed frame 71, the fixed frame 71 is slidably connected to the filtration barrel 2, the fixed frame 71 is provided with a strip plate 72, the strip plate 72 cooperates with the filtration barrel 2, the left part of the frame 1 is symmetrically provided with electric telescopic rods 73, the electric telescopic rods 73 are provided with clamping sleeves 74, the left part of the fixed frame 71 is provided with a second slide rail 75, the second slide rail 75 is slidably provided with a clamping rod 76, and the clamping rod 76 cooperates with the clamping sleeve 74.

[0029] When using the device, after the filtration is completed, the staff controls the electric telescopic rod 73 to extend, and the extension of the electric telescopic rod 73 drives the clamping rod 76 to move upward through the clamping sleeve 74. The clamping rod 76 moves upward and drives the fixing frame 71 to move upward through the second slide rail 75. The fixing frame 71 moves upward and drives the mesh plate 3 to move upward, and then cooperates with the cover plate 4 to squeeze the liquid in the kitchen waste. The fixing frame 71 moves upward and drives the strip plate 72 to move upward, thereby blocking the infiltration bucket 2 to prevent the liquid from flowing out. When the filtration is completed, the staff pushes the clamping rod 76 to slide to the right on the second slide rail 75 to disengage from the clamping sleeve 74, and then pushes the infiltration bucket 2 to dump the kitchen waste. In this way, the mesh plate 3 can be pushed upward to squeeze the liquid in the kitchen waste. Example 2

[0030] On the basis of Example 1, Figure 2 and Figure 5 As shown, it also includes a guide assembly 8, which includes a first fixed rod 81, an inclined frame 82 and a right-angle plate 83. The first fixed rod 81 is provided on the left part of the frame 1, and the inclined frame 82 is provided on the first fixed rod 81. A right-angle plate 83 is provided at an eccentric position at the bottom of the infiltration barrel 2.

[0031] When the device is used, the grease flowing out of the oil outlet drips onto the inclined frame 82 through the right-angle plate 83, and the staff collects it. In this way, it is more convenient for people to collect the grease and prevent the grease from flowing to the bottom of the percolation barrel 2.

[0032] On the basis of Example 1, Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a collecting component 9, which includes a collecting frame 91, a sliding plate 92, a first spring 93, a guide plate 94 and a positioning frame 95. The collecting frame 91 is slidably provided at the lower part of the frame 1, and the collecting frame 91 cooperates with the clamping rod 76. The sliding plate 92 is slidably provided on the left side of the upper part of the collecting frame 91. A first spring 93 is connected between the second slide rail 75 and the clamping rod 76, and the first spring 93 is in a stretched state. There is a guide plate 94 on the right side of the collecting frame 91, and a positioning frame 95 is slidably provided on the guide plate 94, and the positioning frame 95 cooperates with the frame 1.

[0033] When using this device, the grease on the inclined frame 82 flows into the collecting frame 91. When the grease is collected, the staff can pull the positioning frame 95 to slide upward on the guide plate 94 and no longer jam the frame 1, and then pull the collecting frame 91 to slide to the right. The staff collects the grease in the collecting frame 91. The collecting frame 91 slides to the right and no longer jams the card rod 76. Under the action of the first spring 93 resetting, the card rod 76 slides to the right on the second slide rail 75 and disengages from the card sleeve 74. When the staff pushes the collecting frame 91 to slide to the left after collecting the grease, the collecting frame 91 pushes the card rod 76 to slide to the left and jams into the card sleeve 74. The first spring 93 is deformed. In this way, the grease can be collected and the card rod 76 can be automatically disengaged from the card sleeve 74 when the kitchen waste is poured out.

[0034] On the basis of Example 1, Figure 2 , Figure 8 and Fig.10 As shown, the tilting assembly 10 is also included, and the tilting assembly 10 includes a third slide rail 101, a first slider 102, a connecting plate 103, a vertical rod 104, a special-shaped rod 105, a second spring 106, a swing plate 107, a second slider 108, a cross bar 109 and a connecting rod 1010. The third slide rail 101 is provided on both the front and rear sides of the frame 1, and the first slider 102 is slidably provided on the third slide rail 101. The first slider 102 is provided with a connecting plate 103, and the left part of the connecting plate 103 is provided with a vertical rod 104. The vertical rod 101 is provided with a vertical rod 104. 04, a special-shaped rod 105 is slidably provided at the lower part, and the special-shaped rod 105 is matched with the collecting frame 91, and a second spring 106 is wound around the vertical rod 104 and the special-shaped rod 105, and the second spring 106 is in a stretched state, and a swing plate 107 is provided on the front and rear sides of the filtration barrel 2, and a second slider 108 is slidably provided on the swing plate 107, and a cross bar 109 is rotatably provided on the second slider 108, and the cross bar 109 is slidably connected to the frame 1, and a connecting rod 1010 is rotatably provided between the cross bar 109 and the vertical rod 104.

[0035] When the device is used, the collecting frame 91 slides to the right and no longer blocks the special-shaped rod 105. Under the action of the second spring 106 returning to its original position, the special-shaped rod 105 slides to the right on the vertical rod 104 and is clamped into the clamping sleeve 74. At this time, the electric telescopic rod 73 extends to drive the special-shaped rod 105 to move upward. The special-shaped rod 105 moves upward and drives the first slider 102 to slide upward in the third slide rail 101 through the connecting plate 103. The special-shaped rod 105 moves upward and drives the vertical rod 104 to move upward. The vertical rod 104 moves upward and drives the cross bar 109 to slide leftward through the connecting rod 1010. The cross bar 109 moves to the left. The left sliding movement drives the swing plate 107 to swing to the left through the second slider 108, and the swing plate 107 swings to the left and drives the infiltration bucket 2 to tilt to the right to pour out the kitchen waste. After completion, the staff controls the electric telescopic rod 73 to shorten, and the shortening of the electric telescopic rod 73 drives the special-shaped rod 105 to move downward, thereby driving the infiltration bucket 2 to rotate left and reset. When the staff pushes the collection frame 91 to slide to the left after collecting the grease, the collection frame 91 pushes the special-shaped rod 105 to slide to the left and disengage from the sleeve 74, and the second spring 106 is deformed. In this way, the kitchen waste in the infiltration bucket 2 can be automatically poured out.

[0036] On the basis of Example 1, Figure 2 and Fig. 9 As shown, a shielding assembly 11 is also included, and the shielding assembly 11 includes a fixed plate 111, a baffle 112, a third spring 113 and a straight rod 114. The fixed plate 111 is provided on the left part of the frame 1, and a baffle 112 is slidably provided on the left side of the filtration barrel 2. Two third springs 113 are connected between the baffle 112 and the filtration barrel 2, and the third spring 113 is in a stretched state. A straight rod 114 is provided on the baffle 112, and the straight rod 114 cooperates with the fixed plate 111.

[0037] When using the device, the percolation barrel 2 tilts to the right, and drives the straight rod 114 to rotate upward and disengage from the fixed plate 111 through the baffle 112. At this time, under the action of the third spring 113 resetting, the baffle 112 slides downward to block the oil outlet. When the percolation barrel 2 rotates to the left and resets, the baffle 112 drives the straight rod 114 to rotate downward. When the straight rod 114 rotates downward to contact with the fixed plate 111, the fixed plate 111 pushes the straight rod 114 to move upward, and the baffle 112 slides upward to block the oil outlet. The third spring 113 is deformed, so that the oil outlet can be blocked when pouring out kitchen waste to prevent residual grease from flowing out.

[0038] On the basis of Example 1, Figure 2 and Fig.10As shown, it also includes a spreading component 12, which includes a fourth spring 121, a right-angle rod 122, a second fixed rod 123, a special-shaped plate 124 and a fifth spring 125. The fourth spring 121 is connected between the first slide rail 5 and the block 6. The right-angle rod 122 is provided on the block 6. The upper and lower parts of the third slide rail 101 are provided with a second fixed rod 123. A special-shaped plate 124 is slidably provided between the upper and lower second fixed rods 123. The special-shaped plates 124 are matched with the right-angle rod 122, the special-shaped plates 124 are matched with the special-shaped rod 105, and the fifth spring 125 is wound around the special-shaped plate 124 and the second fixed rod 123.

[0039] When using the device, the special-shaped rod 105 slides to the right and pushes the special-shaped plate 124 to slide to the right on the second fixed rod 123, and the fifth spring 125 is deformed. When the special-shaped plate 124 slides to the right and contacts the right-angle rod 122, the special-shaped plate 124 slides to the right and pushes the right-angle rod 122 to move upward. The upward movement of the right-angle rod 122 drives the block 6 to slide upward in the first slide rail 5 and no longer jams the infiltration bucket 2. The fourth spring 121 is deformed. When the special-shaped rod 105 slides to the left and resets to disengage from the special-shaped plate 124, under the action of the fifth spring 125 resetting, the special-shaped plate 124 slides to the left and resets to disengage from the right-angle rod 122. Under the action of the fourth spring 121 resetting, the block 6 slides downward and jams the infiltration bucket 2. In this way, the block 6 can be automatically opened when the kitchen waste needs to be poured out.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
