DETAILED DESCRIPTION
[0021] See also Figure 1-Figure 5The utility model provides the following technical solution: comprising a fermentation tank 1, two horizontal guide rails 2 are arranged in parallel on the top of the fermentation tank 1, the horizontal guide rails 2 are vertically slidably connected to the top of the fermentation tank 1 through a vertical lifter 21, a plurality of collecting plates 3 are slidably connected between the two horizontal guide rails 2, the collecting plates 3 are slidably connected to the horizontal guide rails 2 through a sliding sleeve 32, the opposite sides of two adjacent collecting plates 3 are both provided with an extrusion suction filter 31, and the interior of the collecting plates 3 is a hollow cavity;
[0022] A percolate tank 11 is fixedly connected to one side of the fermentation tank 1, and a receiving tank 33 is provided on the side of the collecting plate 3 close to the percolate tank 11, and a rotary discharge pipe 34 is rotated in the receiving tank 33;
[0023] The collecting plate 3 is connected to an external negative pressure mechanism through a negative pressure suction mechanism 4. The negative pressure suction mechanism 4 includes a main pipeline 41 and a branch pipeline 42. The main pipeline 41 is connected to the negative pressure mechanism. The branch pipeline 42 is fixedly connected to the top of the side of the collecting plate 3 away from the leachate tank 11. The branch pipeline 42 is connected to the inner cavity of the collecting plate 3.
[0024] In this embodiment: an insert plate structure is used so that the collecting plate 3 can be inserted into the compost pile. The structure of the collecting plate 3 is improved, and the filtrate can be squeezed and vacuum filtered to collect the longitudinal leachate of the compost pile, thereby ensuring the longitudinal humidity uniformity during the composting process. At the same time, the collected leachate can be recycled, with a simple structure and high application value.
[0025] To achieve the above functions, the horizontal guide rail 2 is first required to horizontally guide the collection plate 3 to meet the extrusion action. However, the collection of leachate is intermittent, so the vertical lifter 21 drives the horizontal guide rail 2 to lift the horizontal guide rail 2 up and down, so that the horizontal guide rail 2 can be inserted into the fermentation tank 1, and then the horizontal guide rail 2 is inserted into the fertilizer pile. The collection plate 3 slides on the horizontal guide rail 2 through the sliding sleeve 32. When the collection plate 3 descends, the extrusion drive member 5 applies a thrust to the push plate 51 at the collection plate 3, and relative extrusion occurs between the two collection plates 3, so that the liquid naturally enters the internal cavity of the collection plate 3 through the extrusion suction filter 31, completing the extrusion leachate collection.
[0026] Vacuum collection will not squeeze the fertilizer. After the collecting plate 3 is inserted, the air on the top of the internal cavity of the collecting plate 3 is discharged through the main pipeline 41, so that a negative pressure environment is gradually formed inside the collecting plate 3, so that the liquid enters the cavity of the collecting plate 3 to complete the collection. After the collection is completed, the horizontal guide rail 2 drives the collecting plate 3 to rise. When the rotary discharge pipe 34 is not affected by the side wall of the leachate tank 11, the rotary discharge pipe 34 is naturally affected by gravity and rotates downward. The liquid level is higher than the rotary discharge pipe 34, and the liquid is discharged into the leachate tank 11 to complete the collection.
[0027] The rotary discharge pipe 34 includes a discharge pipe 341, a rotary support mechanism 342, and a flexible curved hose 343. The flexible curved hose 343 is fixed at the bottom of the storage groove 33. The rotary support mechanism 342 is installed at the connection between the discharge pipe 341 and the flexible curved hose 343. A sealed drainage gravity blocking cone 6 is installed in the discharge pipe 341. When the collecting plate 3 descends, the discharge pipe 341 is rotated and stored in the inside of the storage groove 33 through the rotary support mechanism 342. When the collecting plate 3 rises, the rotary support mechanism 342 drives the discharge pipe 341 to rotate downward, and the flexible curved hose 343 will not affect the rotation process.
[0028] The inner wall of the discharge pipe 341 is fixedly connected with a contraction port 61, the inclined surface of the contraction port 61 is located at the top, the top of the inclined surface of the contraction port 61 is provided with a sealed drainage gravity plugging cone 6, the bottom of the sealed drainage gravity plugging cone 6 is fixedly connected with a connecting rod 62, the side of the connecting rod 62 is fixedly connected with a limiting rod 63, and the contraction port 61 is located between the sealed drainage gravity plugging cone 6 and the limiting rod 63; the above description requires vacuum suction, in order to simplify the structure to ensure sealing and action continuity, a sealed drainage gravity plugging cone 6 is provided, and the rotary discharge pipe 34 is vertically connected to the rotary discharge pipe 34. In this state, the sealed drainage gravity plugging cone 6 is affected by gravity and contacts the contraction port 61. Under the action of vacuum suction, the sealed drainage gravity plugging cone 6 contacts the contraction port 61 to ensure sealing. When descending, the exhaust valve of the negative pressure suction mechanism 4 opens, and the sealed drainage gravity plugging cone 6 is not affected by the negative pressure. After the rotary discharge pipe 34 rotates to the bottom, the sealed drainage gravity plugging cone 6 separates from the contraction port 61 by its own weight, and the limiting rod 63 limits the connecting rod 62, forming a liquid flow gap between the sealed drainage gravity plugging cone 6 and the contraction port 61.
[0029] The width of the collecting plate 3 is consistent with the width of the fermentation tank 1, and a rubber layer is provided on the contact surface between the collecting plate 3 and the side wall of the fermentation tank 1; the rubber layer can ensure the sliding sealing between the collecting plate 3 and the fermentation tank 1, and the inner wall of the fermentation tank 1 can also be provided with a Teflon structure for sealing.
[0030] A push plate 51 is slidably connected inside the fermentation tank 1 , and the push plate 51 is fixedly connected to the output end of the extrusion drive member 5 ; the push plate 51 can disperse the large thrust to avoid elastic deformation of the collecting plate 3 .
[0031] The branch pipe 42 is a hose; the soft branch pipe 42 can ensure that the horizontal guide rail 2 will not interfere with the movement when it moves up and down.
