Description

Technical Field

[0001] This utility model relates to the field of waste incineration pretreatment technology, specifically to a waste receiving, storage and pretreatment channel structure. Background Technology

[0002] In the waste management industry, due to the large volume of waste, it is stored in a waste storage area near the incinerator before entering the furnace. During this storage process, due to factors such as storage time, material type, and stacking condition, leachate cannot be completely separated from the waste in the storage area and is thus grabbed by a grab bucket and transported to the feed inlet of the grate incinerator. This excessive leachate remaining in the waste reduces the combustion efficiency of the incinerator, increases pollutant emissions, increases the pressure on subsequent processing equipment, and increases energy costs.

[0003] Therefore, if the waste can be pre-treated before entering the incinerator, more leachate can be discharged, and the waste can be dried and preheated, the subsequent waste incineration effect will be significantly improved. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a waste receiving, storage, and pre-processing channel structure.

[0005] The technical solution of this utility model is as follows: a waste receiving, storage and pre-treatment channel structure, the channel structure includes a feed inlet, a drying ramp, a discharge inlet, an air inlet, an air outlet and a recycling chamber. The drying ramp includes a high point end connected to the feed inlet and a low point end connected to the discharge inlet. The recycling chamber is located vertically below the drying ramp. Both the feed inlet and the discharge inlet are equipped with electrically controlled doors that can be opened, closed and sealed. The air inlet is located in the drying ramp and the air outlet is located in the recycling chamber. The drying ramp is provided with several installation grooves and several first seepage through holes that penetrate to the recovery chamber along the direction from the high point to the low point. Each of the installation grooves is provided with an arching mechanism. The side of the installation groove near the high point is provided with a hinge shaft and the side near the low point is provided with a transition slope. The two ends of the transition slope connect the bottom of the installation groove and the slope of the drying ramp. The arching mechanism includes a first flap, a second flap, a drive piston rod, and a hydraulic drive assembly. The first flap is provided with a first end that is hinged to the hinge shaft and a second end that is hinged to the second flap. The second flap is provided with a third end that is hinged to the drive piston rod. The surfaces of the first flap and the second flap are both provided with second seepage holes. The hydraulic drive assembly is located on one side of the transition slope of the installation groove and is linked with the drive piston rod. The hydraulic drive assembly drives the second flap to approach the first flap and causes the second end to arch away from the installation groove, forming a stepped barrier to prevent garbage from sliding down the drying slope. The hydraulic drive assemblies are linked by signals to drive each installation groove of the drying slope to arch or flatten. The air inlet receives air heated by the waste heat of the incineration flue gas, and the exhaust outlet is equipped with an induced draft fan. The waste-heated air passes through the garbage on the drying slope and enters the recovery chamber together with the leachate through the first leachate passage and the second leachate passage. The recovery chamber is equipped with a centralized drainage pipeline.

[0006] Using the above technical solution, the hydraulic drive component is a conventional hydraulic element, which typically consists of components such as hydraulic cylinders, hydraulic pumps, control valves, and pipeline joints.

[0007] A further feature of this invention is as follows: A hinge shaft and a long circular hole are provided on the side wall of the channel corresponding to each mounting slot. The long circular hole is parallel to the bottom surface of the mounting slot and located at the third end of the second flap. The drive piston rod is L-shaped, with one end connected to the hydraulic drive assembly and the other end passing through to form a long circular hole, which is hinged to the third end. A blocking part is provided at the third end, which arches up with the second end and always blocks the long circular hole.

[0008] A further feature of this invention is that the channel structure has a material discharge chamber at the inlet, a partition is provided between the material discharge chamber and the air inlet, and an opening is provided between the material discharge chamber and the drying ramp.

[0009] A further feature of this invention is that a material pushing mechanism is provided at the opening.

[0010] The above technical solution, with its drop chamber design, allows the garbage in the grab bucket to fall from a height, breaking up the garbage structure. It generally slides directly down the drying ramp; if necessary, a propulsion mechanism can be installed to assist in pushing the garbage down.

[0011] A further feature of this invention is that the bottom of the recovery chamber is shaped like a bucket, a filter screen is provided at the opening of the bucket, and the recovery chamber is equipped with a slag removal door.

[0012] The beneficial effects of this utility model are as follows: Through the independent or linked arching mechanism of each installation slot, a stepped structural change is formed, so that the garbage sliding down the drying slope can be stopped by the arched first flap and second flap. During the process of the garbage being stopped, piling up, overturning the stop, or sliding down again after the arching mechanism returns to flat, the movement posture of the garbage remains dynamically changing, thereby breaking up the garbage and further separating the leachate in the garbage, which drips from the leachate through hole into the recycling chamber.

[0013] Meanwhile, air heated by the waste heat of the incineration flue gas is introduced into the air inlet of the channel. While the hot air pre-dries the garbage, it also carries the leachate into the recycling chamber. The exhaust vent of the recycling chamber draws out the gas in the channel and introduces it into the grate along with the garbage odor as primary air.

[0014] After being dried in the drying ramp, the waste enters the incinerator through the discharge port.

[0015] In a further design, the oblique part of the path is structurally coordinated with the oblique part to ensure that the oblique part always blocks the oblique part of the path when the arched posture of the second flap changes, thus preventing garbage from rolling in and optimizing the transmission design.

Both the inlet 1 and the outlet 3 are equipped with electrically controlled doors 31 that can be opened, closed, and sealed. The air inlet 4 is located in the drying ramp 2, and the exhaust outlet 5 is located in the recycling chamber 6. The drying ramp 2 is provided with a number of installation grooves 21 and a number of first seepage through holes 22 that penetrate into the recovery chamber 6 along the direction from the high point end to the low point end. Each of the installation grooves 21 is provided with an arching mechanism. A hinge shaft 23 is provided on the side of the installation groove 21 near the high point end and a transition slope 24 is provided on the side near the low point end. The two ends of the transition slope 24 connect the bottom of the installation groove 21 and the slope surface of the drying ramp 2. The arching mechanism includes a first flap 25, a second flap 26, a drive piston rod 27, and a hydraulic drive assembly 28. The first flap 25 is provided with a first end 251 that is hinged to the hinge shaft 23 and a second end 252 that is hinged to the second flap 26. The second flap 26 is provided with a third end 261 that is hinged to the drive piston rod 27. The surfaces of the first flap 25 and the second flap 26 are both provided with second seepage holes 29. The hydraulic drive assembly 28 is located on one side of the transition slope of the mounting groove 21 and is linked with the drive piston rod 27. The hydraulic drive assembly 28 drives the second flap 26 to approach the first flap 25 and causes the second end 252 to arch away from the mounting groove 21, forming a stepped barrier to prevent garbage from sliding down the drying slope 2. The hydraulic drive assemblies 28 are linked by signals to drive each mounting groove 21 of the drying slope 2 to arch or flatten. The air inlet 4 receives air heated by the waste heat of the incineration flue gas, and the exhaust outlet is equipped with an induced draft fan. The waste heat-heated air passes through the garbage on the drying ramp 2 and enters the recovery chamber 6 together with the leachate through the first leachate passage 22 and the second leachate passage 29. The recovery chamber 6 is equipped with a centralized drainage pipeline.

[0022] On the side wall of the channel, a hinge shaft 23 and a long circular hole 231 are provided corresponding to each mounting slot 21. The long circular hole 231 is parallel to the bottom end face of the mounting slot 21 and is located at the third end 261 of the second flap 26. The drive piston rod 27 is L-shaped, with one end connected to the hydraulic drive assembly 28 and the other end passing through to form a long circular hole and hinged to the third end 261. A blocking part 232 is provided at the third end 261. The blocking part 232 arches up with the second end 252 and always blocks the long circular hole 231.

[0023] The channel structure has a discharge chamber 11 at the feed inlet 1. The discharge chamber 11 is separated from the air inlet 4 by a partition and has an opening between it and the drying ramp 2.

[0024] A material pushing mechanism is provided at the opening.

[0025] The design of the discharge chamber 11 allows the garbage from the grab bucket to fall from a height, breaking up the garbage structure. Generally, it slides directly down the drying ramp 2. If necessary, a propulsion mechanism can be installed to assist in pushing the garbage down.

[0026] The bottom of the recycling chamber 6 is shaped like a bucket, and a filter screen is installed at the opening of the bucket. The recycling chamber 6 is also equipped with a slag removal door.

[0027] Through the independent or linked arching mechanisms of each installation slot 21, a stepped structural change is formed, so that the garbage sliding down the drying slope 2 can be stopped by the arched first flap 25 and second flap 26. During the process of the garbage being stopped, piling up, overturning the stop, or sliding down again after the arching mechanism returns to flat, the movement posture of the garbage remains dynamically changing, thereby breaking up the garbage and further separating the leachate in the garbage, which drips from the leachate through hole into the recycling chamber 6.

[0028] At the same time, air heated by the waste heat of the incineration flue gas is introduced into the air inlet 4 in the channel. While the hot air pre-dries the garbage, it also carries the leachate into the recycling chamber 6. The exhaust vent 5 of the recycling chamber 6 exhausts the gas in the channel and introduces it into the grate along with the garbage odor as primary air.

[0029] After being dried in the drying ramp 2, the waste enters the incinerator through the discharge port 3.

[0030] In a further design, the obstruction mechanism, through the structural cooperation of the path elongated hole and the shielding part, ensures that the shielding part 232 always blocks the path elongated hole when the arched posture of the second flap changes, thus preventing garbage from rolling in and optimizing the transmission design.

Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
