Description

Technical Field

[0001] This utility model relates to the field of solid waste melting treatment, specifically to a feeding system for a solid waste treatment melting furnace. Background Technology

[0002] In the treatment of hazardous waste in furnaces, materials prepared in a specific ratio need to be transported from the batching area to the furnace top and then unloaded into the furnace for processing. This process involves both horizontal and vertical movement of the materials. Therefore, the unloader typically needs to be fed from above and unloaded from below. To prevent material from falling during vertical lifting, the unloader's bottom plate must reliably close; conversely, after the unloader is lifted to the furnace top, the bottom plate must reliably open to allow material to enter the furnace. Therefore, controlling the unloader's bottom plate is a key aspect of its design.

[0003] Traditional unloader base plates are opened and closed by motors or hydraulic devices. The unloader needs to receive materials from the feeder and then transfer them to the furnace top through processes such as translation and hoisting to complete the unloading. Its movement stroke is relatively long. The unloading method driven by motors or hydraulics requires additional hydraulic systems or additional cables, which brings inconvenience to the hoisting of the system and is prone to failure during the unloading process, affecting the production schedule. Summary of the Invention

[0004] To meet the raw material unloading needs of solid waste melting and disposal, ensure the reliability of the unloading process, and save equipment costs, this utility model provides a feeding system for solid waste melting furnaces, realizing a complete set of procedures from loading and transportation, hoisting, and unloading.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A feeding system for a solid waste treatment melting furnace includes a batching device and a discharger. The batching device is supported on a batching rack, and a pair of upper rails are installed on the top surface of the batching rack. Rollers that cooperate with the upper rails are installed on both sides of the batching device in the width direction. The lower half of the batching device is suspended inside the batching rack. A pair of lower rails are installed on the inner bottom surface of the batching rack, and a flat trolley is supported on the lower rails. The bottom rollers of the flat trolley cooperate with the lower rails. The discharger is supported on the flat trolley and is located directly below the batching device. The batching device includes a batching hopper with an opening at the top and a double-leaf gate installed at the bottom. The discharger includes a hopper, which is a rectangular cavity with an opening at the top that corresponds to the gate at the bottom of the batching device. A double-leaf bottom plate is installed at the bottom of the hopper, and the double-leaf bottom plate corresponds to the feed inlet at the top of the melting furnace.

[0007] Furthermore, the gate of the batching device is connected to the two sides of the bottom width direction of the batching hopper through multiple hinges, and the two ends of the gate extend out of the two ends of the batching hopper in the length direction; hydraulic cylinders and hydraulic stations are respectively installed at the two ends of the batching hopper in the length direction, and the hydraulic cylinders are set vertically; each extended end of the gate is equipped with an ear plate, and the telescopic end of the hydraulic cylinder is connected to a triangular connection. The ear plates are respectively connected to the triangular connecting plate through connecting rods, and the telescopic end of the hydraulic cylinder is hinged to the upper corner of the triangular connecting plate. The two connecting rods are respectively hinged to the two lower corners of the triangular connecting plate.

[0008] Furthermore, the bottom plate of the unloader is connected to the two sides of the bottom of the hopper in the width direction via hinges. The two ends of the bottom plate extend along the length direction of the hopper, and lifting lugs are welded to the extended ends of the bottom plate respectively. Lifting rods are installed at the center of the end faces of the two ends of the hopper in the length direction. The bottom of the lifting rods is connected to the lifting lugs of the two bottom plates at the same end via a pair of chains. The lifting rods are limited by guide rings installed on the end faces of the hopper and move vertically along the guide rings. A horizontal connecting rod is welded to one side of the top of the lifting rod. A limit ring is welded to the end face of the connecting rod. The connecting rod cooperates with the hook of the crane.

[0009] Furthermore, support portions extending along the length direction are welded to both sides of the hopper in the width direction, and the support portions are supported by a support at the top feed inlet of the melting furnace.

[0010] Furthermore, a speed reducer is connected to the side of the feeder, and the output end of the speed reducer is connected to the roller.

[0011] Furthermore, the opening width of the split gate corresponds to the width of the top opening of the hopper.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0013] The feeding system consists of a batching device and a discharger. The batching device moves on the batching rack to load the prepared mixture, and the extension and retraction of the hydraulic cylinder opens the bottom gate, transferring the material to the discharger directly below. The discharger is moved horizontally by a flatbed trolley and vertically lifted by a crane. During the trolley's horizontal movement, it supports the split bottom plate of the discharger. During lifting, the tension of the crane hook keeps the bottom plate closed. After the discharger is supported at the top of the melting furnace, the bottom opens freely under gravity, and the material in the hopper enters the melting furnace. The technical solution of this application enables continuous collaborative work of multiple batching devices and dischargers, achieving uninterrupted feeding and improving efficiency. At the same time, the discharger avoids the use of hydraulic or electric drives, has a simple structure, low cost, and better discharge stability. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] As shown in the figure, the feeding system for the solid waste treatment melting furnace consists of a batching device 1, a batching rack 2, a discharger 3, and a crane 4. It is used to receive crushed solid waste and catalysts, and to complete the loading, transportation, hoisting, and finally discharge at the top of the melting furnace.

[0020] The batching rack 2 can be formed by two vertical walls or a concrete structure instead of two walls to create a passage. Each wall has an upper rail 5 installed at its top, and the batching device 1 slides on the upper rail. The main structure of the batching device is a batching hopper 11. The top of the batching hopper 11 is open to receive materials. The bottom of the batching hopper 11 is fitted with a hinged double-leaf gate 12. The opening of the double-leaf gate 12 is driven by hydraulic cylinders 13 installed on the end faces of both ends of the batching hopper along its length. The hydraulic stations corresponding to the hydraulic cylinders 13 are also fixedly installed at the ends of the batching hopper 11 or on the vertical wall. Each gate 12 extends beyond the length of the batching hopper 11. Each extended end of the gate 12 is fitted with an ear plate 15, and each ear plate 15 is hinged to a connecting rod 16 or a chain. The telescopic ends of the hydraulic cylinders 13 and the two connecting rods 16 are hinged to the three corners of a triangular connecting piece 17. When the hydraulic cylinder 13 extends, the gate 12 opens under the action of gravity and internal material pressure, and the connecting rod 16 or chain limits the opening angle; when the hydraulic cylinder 13 retracts, the connecting rod 16 pulls the gate 12 to close, sealing the bottom of the batching hopper 11.

[0021] Multiple sets of rollers 18, which cooperate with the upper rail 5, are installed on the upper middle part of both sides of the batching hopper 11 in the width direction to realize the horizontal movement of the batching hopper 11. The lower half of the batching hopper 11 is suspended between two vertical walls to prevent dust from being generated during material feeding. In order to improve the degree of automation, drive devices 14 are installed on both sides of the batching hopper in the width direction. The drive devices 14 are selected as reducer devices, and the motor drives the rotating shaft of the rollers 18 to rotate after being reduced in speed by the reducer.

[0022] The unloader 3 is located in a passage between two vertical walls. A pair of lower rails 6 are installed on the floor of the passage, with the upper and lower rails parallel to each other. A flatbed trolley 7 is supported on the lower rails 6, and the bottom rollers of the flatbed trolley 7 cooperate with the lower rails 6. The unloader 3 is supported on the flatbed trolley 7 and is located directly below the batching device 1. When the bottom gate 12 of the batching device 1 is opened, the material is transferred to the unloader 3, and the movement of the flatbed trolley 7 causes the unloader 3 to move horizontally.

[0023] The main structure of the unloader 3 is a hopper 31, which is a rectangular cavity. The top opening of the hopper 31 corresponds vertically to the gate 12 at the bottom of the feeder 1, and the opening width of the gate 12 corresponds to the opening width of the top of the hopper 31. A split bottom plate 32 is installed at the bottom of the hopper 31, and the opening degree of the split bottom plate 32 corresponds to the feed inlet at the top of the melting furnace.

[0024] The bottom plate 32 of the unloader 3 is connected to the two sides of the bottom width direction of the hopper via hinges or a rotating shaft. The two ends of the bottom plate 32 extend along the length direction of the hopper 31. The extended ends of the bottom plate 32 are respectively welded with lifting lugs 33. The center of the end face of the two ends of the hopper 31 along the length direction is respectively installed with lifting rods 34. The bottom of the lifting rods 34 is connected to the lifting lugs 33 of the two bottom plates 32 at the same end via a pair of chains 35. The lifting rods 34 are limited by the guide rings 38 installed on the end face of the hopper 31 and can move vertically along the guide rings 3 and 8. A horizontal connecting rod 36 is welded to one side of the top of the lifting rod 34. The end face of the connecting rod 36 is welded with a limit ring. The connecting rod 36 cooperates with the hook of the crane 4.

[0025] After the unloader 3 is filled with material, the flatbed trolley 7 moves the unloader 3 horizontally under the traveling crane 4. During this process, the bottom plate of the unloader 3 is supported by the flatbed trolley 7 and is in a closed state. The hook of the traveling crane 4 connects to the lifting rods 34 on both sides of the unloader 3 hopper and lifts it. During this process, the bottom plate 32 remains closed due to the tension of the chain. After being lifted to the top feed inlet of the melting furnace, the support parts 37 welded on both sides of the width direction of the hopper 31 are supported by the supports at the top feed inlet of the melting furnace. At this time, the hook of the traveling crane 4 is released from the load, and the bottom plate 32 of the hopper 31 opens at the top feed inlet of the melting furnace under the action of gravity and the pressure of the internal material, and the internal material enters the furnace, completing the unloading. After the unloading is complete, the traveling crane 4 lifts the empty unloader 3 back and places it on the flatbed trolley 7, and begins the next cycle.
