Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

The solid waste incinerator feeding platform shown in the attached drawing is divided into a plurality of units (four units are shown in the drawing, namely four rows are arranged side by side) which are arranged in parallel and side by side, each unit comprises a sliding platform 2 (the sliding platform is positioned outside the incinerator and is ready to push garbage along a guide rail fixed at the top end of a feeding frame, and fig. 2 shows that the sliding platform pushes the garbage into the incinerator, so that the garbage passes through a casting 4 at the front end of the feeding platform and then slides down to a fire grate to be incinerated) and a hydraulic device (positioned at the left side of fig. 1) for driving the sliding platform; wherein: a percolate collecting hopper is arranged below the hydraulic device; a front-end casting 4 (capable of bearing high temperature in the furnace) of the feeding platform for bearing garbage is arranged below the sliding platform, and a guide groove 5 of the feeding platform communicated with a percolate collecting hopper is arranged below the front-end casting; as can be seen from the figure, the guiding gutter of the feeding platform is relatively flat, and if there is deposit, the percolate is easy to be retained.

The structure is similar to the structure of the feeding platform of the conventional solid waste incinerator.

In the actual operation process, fine garbage or incombustible components on the feeding platform often leak downwards through a gap of a casting at the front end of the feeding platform and are accumulated in a diversion trench of the feeding platform, so that percolate is retained in the diversion trench; if the leachate is not cleaned in time, the leachate cannot be normally discharged and overflows, so that the environment is greatly influenced.

The utility model is an improvement, firstly, a pipeline 3d for guiding and discharging the percolate is added; the pipeline intercommunication is between filtration liquid collection fill and feed platform guiding gutter (can set up one or more than two pipelines as required between filtration liquid collection fill and feed platform guiding gutter) for filtration liquid can be arranged outward at any time, thereby solves because of the excessive problem that influences the environment of filtration liquid. Secondly, a spraying component 3c externally connected with a water source (preferably tap water) is arranged on the feeding platform.

Further, the pipeline is provided with an inclination (the inclination is set according to requirements) so that the percolate can smoothly flow into the percolate collecting hopper.

The spraying component 3c comprises a plurality of nozzles 3f communicated with a water source; the nozzles are distributed around the percolate collecting hopper, and the nozzle openings are aligned to the inner wall of the percolate collecting hopper and can be opened periodically (or according to requirements) to wash away accumulated liquid and slag in the percolate collecting hopper, so that the blockage phenomenon is prevented; the flushing water can flow into the percolate collecting hopper through a pipeline.

In addition, a quick access door 3b is also provided on one side of the percolate collecting hopper (visible on the left in fig. 3) and can be used for cleaning up refuse and for regular maintenance. As can be seen from fig. 6: the access door is of a quick opening and closing structure and comprises a door cover 3b1 with a handle 3b4 and wedges 3b3 (the wedges are arranged on the outer edge of the door cover), a plurality of bolts for fixing the door cover on an access door hole and pressing blocks 3b2 (the bolts with the pressing blocks are arranged on the edges of door frames in one-to-one correspondence with the wedges) which are rotatably positioned on the bolts, wherein the opening and closing of the access door can be quickly realized through the cooperation of the rotary pressing blocks and the corresponding wedges. During the production of the test cases in the factory, the individual components of the percolate discharge apparatus can be mounted on a feed platform and adjusted for calibration. Then transporting the sliding platform to a construction site; after the device is on site, the device can be simply constructed and installed according to the requirements of the drawing so as to ensure the quality and the precision of the device.
