Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment equipment technology, and in particular to a feeding mechanism for a solid waste incinerator. Background Technology

[0002] For the treatment of solid waste, the solid waste is usually collected and then incinerated. The solid waste is placed in a combustion chamber and burned. The combustion chamber is equipped with an incinerator, a purification device, etc. After the incinerator is completed, the exhaust gas is purified by the purification device and then discharged into the outside air.

[0003] A search revealed a patent document with publication number "CN220669460U" that discloses a solid waste combustion rotary kiln feeding mechanism, including a receiving body and a processing shell connected to the receiving body. The receiving body is provided with a predetermined receiving chamber to receive solid waste to be incinerated, and a pushing component is provided inside to push the solid waste into the processing shell. The bottom of the processing shell is provided with a feeding channel connected to the kiln head of the rotary kiln. The processing shell is provided with a stirring and crushing component, including a rotating shaft rotatably installed between the inner walls of the two sides of the processing shell and a stirring component mounted on the rotating shaft. The side wall of the stirring component forms a cutting edge along its length to perform stirring and crushing operations on the solid waste. The solid waste processed by the stirring and crushing component is fed continuously and incinerated in the rotary kiln with stable calorific value.

[0004] The aforementioned solid waste combustion rotary kiln feeding mechanism can also be used on incinerators; simply connect the feeding channel to the incinerator's feeding channel.

[0005] Based on the above search and combined with existing technology, it was found that the existing feeding mechanism is equipped with a pull-out baffle. The pull-out baffle can control the feeding of solid waste, but it often requires manual operation by the staff or is driven by a power component (such as an electric push rod or hydraulic rod). When using a power component, it is also necessary to be equipped with a corresponding controller or sensor to achieve the purpose of intermittently opening the pull-out baffle so that the solid waste in the processing shell can be crushed more completely. This will undoubtedly lead to an increase in the overall cost and operating cost (energy consumption) of the feeding mechanism. Therefore, a feeding mechanism for solid waste incinerators is needed. Utility Model Content

[0006] The purpose of this application is to provide a feeding mechanism for a solid waste incinerator to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a feeding mechanism for a solid waste incinerator, comprising a base, a lifting column fixed on the base, and a body installed on the upper end of the lifting column. The body includes a receiving hopper fixed to the upper end of the lifting column, a processing box located on one side of the receiving hopper, a connecting pipe for connecting the receiving hopper and the processing box, and a feeding hopper fixed to and connected to the lower end of the processing box. A pushing structure is installed on the receiving hopper, and a crushing and agitating structure is installed on the processing box.

[0008] An opening is provided on one side of the feeding hopper, and a rotating circular plate is rotatably engaged inside the opening. The rotating circular plate has a through hole with the same inner diameter as the feeding hopper.

[0009] The central axis of the rotating disc is parallel to the central axis of the hopper, and the central axis of the rotating disc is located on the side of the hopper closest to the lifting column.

[0010] The rotating shaft of the pusher structure drives the rotating circular plate to rotate synchronously through the transmission mechanism.

[0011] Preferably, the transmission mechanism includes a semi-free drive mechanism and a transmission assembly. The semi-free drive mechanism is mounted on a rotating circular plate, and the transmission assembly is connected to the rotating shaft of the semi-free drive mechanism and the pusher structure.

[0012] Preferably, the semi-free drive mechanism includes a sleeve shaft and a drive rod. The outer side of the sleeve shaft is fixed to a rotating circular plate, and a clearance groove with one side being a straight wall is opened on the inner side of the sleeve shaft. The drive rod moves through the sleeve shaft. The upper end of the drive rod is connected to the output end of the transmission assembly, and the lower end of the drive rod is rotatably connected to the upper surface of the base. A limiting blade plate that fits against the straight wall of the clearance groove is vertically slidably connected to the periphery of the drive rod, and the length of the limiting blade plate is less than the width of the straight wall of the clearance groove.

[0013] The clearance groove forms an arc-shaped wall that intersects with the straight wall, and the arc-shaped wall gradually converges towards the middle shaft of the sleeve.

[0014] Preferably, a second magnetic block is fixedly embedded in the rotating circular plate. The second magnetic block is located on the side of the forward direction of the through hole rotation and is located at the edge of the rotating circular plate.

[0015] A first magnetic block is fixed at the bottom of the processing box. The first magnetic block and the second magnetic block are magnetically attracted to each other. When the first magnetic block and the second magnetic block attract each other, the through hole coincides with the position of the feeding hopper.

[0016] Preferably, an inclined ring is formed around the through hole, the inner diameter of the upper end of the inclined ring is larger than the inner diameter of the lower end of the inclined ring, and the angle between the inclined ring and the bottom surface of the rotating circular plate is less than 45°.

[0017] Preferably, a lifting bracket is also fixed at the upper end of the base, and a ring frame is fixed on one side of the movable part of the lifting bracket. The ring body of the ring frame is fixedly sleeved on the feeding hopper, and the ring frame is located below the rotating circular plate.

[0018] The movable part of the ring frame has integrated reinforcing side frames on both the front and rear sides, which are fixed to the front and rear sides of the processing box.

[0019] Preferably, the base is also provided with mounting holes for the feed end of the incinerator to pass through, and the mounting holes correspond to the position of the feeding hopper.

[0020] In summary, the technical effects and advantages of this utility model are as follows:

[0021] 1. In this utility model, through the setting of the transmission mechanism and the rotating circular plate, when the pushing structure rotates, its rotating shaft drives the rotating circular plate to rotate synchronously through the transmission mechanism. When the rotating circular plate rotates, its other areas except the through hole are located in the feeding hopper, the feeding hopper is in a closed state. When the through hole coincides with the position of the feeding hopper, the feeding hopper is in an open state, so that the crushed and mixed solid waste in the processing box falls from the feeding hopper and enters the incinerator, thus completing the feeding of solid waste.

[0022] Because the overlap time between other areas of the rotating disc and the feeding hopper is relatively long, the crushing and agitation structure has sufficient time to crush and agitate the solid waste located in the processing box, thereby achieving the purpose of intermittent feeding to the incinerator. The use of a transmission mechanism and a rotating disc not only achieves the purpose of intermittent feeding, but also avoids the need for additional power components, controllers, sensors, etc., thereby reducing the overall cost and operating cost of the feeding mechanism for solid waste incinerators.

[0023] 2. In this utility model, the arrangement of the first magnetic block, the second magnetic block, the sleeve shaft, and the drive rod can provide sufficient unloading time for solid waste in the processing box and meet the intermittent opening and closing requirements of the feeding hopper, thus achieving a better usage effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example: Reference Figures 1-5 The feeding mechanism for a solid waste incinerator shown includes a base 1, a lifting column 2 fixed on the base 1, and a body 3 installed on the upper end of the lifting column 2. The body 3 includes a receiving hopper 31 fixed to the upper end of the lifting column 2, a processing box 32 located on one side of the receiving hopper 31, a connecting pipe 33 for connecting the receiving hopper 31 and the processing box 32, and a feeding hopper 34 fixed to and connected to the lower end of the processing box 32. A pushing structure 4 is installed on the receiving hopper 31, and a crushing and agitating structure 5 is installed on the processing box 32. Both the pushing structure 4 and the crushing and agitating structure 5 are driven by a motor.

[0033] An opening 341 is provided on one side of the feeding hopper 34. A rotating circular plate 6 is rotatably engaged in the opening 341. A through hole 61 with the same inner diameter as the feeding hopper 34 is provided on the rotating circular plate 6.

[0034] The central axis of the rotating circular plate 6 is parallel to the central axis of the feeding hopper 34, and the central axis of the rotating circular plate 6 is located on the side of the feeding hopper 34 closer to the lifting column 2.

[0035] The rotating shaft of the pusher structure 4 drives the rotating circular plate 6 to rotate synchronously through the transmission mechanism.

[0036] Based on the above structure, when the pusher structure 4 rotates, its rotating shaft drives the rotating circular plate 6 to rotate synchronously through the transmission mechanism. When the rotating circular plate 6 rotates, its other areas except for the through hole 61 are located in the feeding hopper 34, and the feeding hopper 34 is in a closed state. When the through hole 61 coincides with the position of the feeding hopper 34, the feeding hopper 34 is in an open state, so that the solid waste that has been crushed and mixed in the processing box 32 falls from the feeding hopper 34 and enters the incinerator, thus completing the feeding of solid waste.

[0037] Since the overlap time between other areas of the rotating disc 6 and the feeding hopper 34 is relatively long, the crushing and agitation structure 5 has sufficient time to crush and agitate the solid waste located in the processing box 32, thereby achieving the purpose of intermittent feeding to the incinerator. The use of the transmission mechanism and the rotating disc 6 not only achieves the purpose of intermittent feeding, but also avoids the need to set up additional power components, controllers, sensors, etc., thereby reducing the overall cost and operating cost of the feeding mechanism for solid waste incinerator.

[0038] In addition, in order to ensure that the solid waste is fully crushed and to prevent the solid waste from falling as soon as it enters the processing box 32, the overlapping posture of the through hole 61 and the feeding hopper 34 should be separated from the posture of the pushing structure 4 pushing the solid waste into the connecting pipe 33. Preferably, when the pushing structure 4 pushes the solid waste into the connecting pipe 33, the through hole 61 and the feeding hopper 34 are completely separated after overlapping.

[0039] Furthermore, the transmission mechanism includes a semi-free drive mechanism 7 and a transmission assembly 8. The semi-free drive mechanism 7 is mounted on the rotating circular plate 6, and the transmission assembly 8 is connected between the semi-free drive mechanism 7 and the rotating shaft of the pusher structure 4. The transmission assembly 8 adopts a transmission structure commonly used in the prior art, such as a transmission wheel and transmission belt, a transmission sprocket and transmission chain, a transmission shaft, etc., in order to achieve a stable transmission effect.

[0040] Specifically, the semi-free drive mechanism 7 includes a sleeve shaft 71 and a drive rod 72. The outer side of the sleeve shaft 71 is fixed to the rotating circular plate 6. A clearance groove 711 with one side being a straight wall is opened on the inner side of the sleeve shaft 71. The drive rod 72 movably passes through the sleeve shaft 71. The upper end of the drive rod 72 is connected to the output end of the transmission assembly 8. The lower end of the drive rod 72 is rotatably connected to the upper surface of the base 1. A limiting blade 721 that fits against the straight wall of the clearance groove 711 is vertically slidably connected to the periphery of the drive rod 72. The length of the limiting blade 721 is less than the width of the straight wall of the clearance groove 711.

[0041] Among them, the relief groove 711 forms an arc-shaped wall that intersects with the straight wall, and the arc-shaped wall gradually converges towards the intermediate axis of the sleeve shaft 71.

[0042] Furthermore, a second magnetic block 62 is fixedly embedded on the rotating circular plate 6. The second magnetic block 62 is located on the side of the forward direction of the rotation of the through hole 61, and the second magnetic block 62 is located at the edge of the rotating circular plate 6.

[0043] The bottom of the processing box 32 is fixed with a first magnetic block 321. The first magnetic block 321 and the second magnetic block 62 are magnetically attracted to each other. When the first magnetic block 321 and the second magnetic block 62 attract each other, the through hole 61 coincides with the position of the feeding hopper 34.

[0044] With the arrangement of the first magnetic block 321, the second magnetic block 62, the sleeve shaft 71, and the drive rod 72, during use, when the rotating shaft of the pushing structure 4 rotates, the drive rod 72 is driven to rotate through the transmission assembly 8. When the drive rod 72 rotates, it abuts against the straight wall of the relief groove 711 through the limiting blade 721, thereby driving the sleeve shaft 71 to rotate. When the sleeve shaft 71 rotates, it drives the rotating circular plate 6 to rotate. During the rotation, when the second magnetic block 62 approaches the first magnetic block 321 (at this time, the through hole 61 and the feeding hopper 34 are about to overlap), the second magnetic block 62 quickly approaches the first magnetic block 321 under the magnetic attraction, and drives the rotating circular plate 6 to rotate faster. Due to the existence of the relief groove 711, This allows the sleeve shaft 71 to rotate at a relatively fast speed, thereby causing the straight wall of the relief groove 711 to disengage from the limiting blade 721, thus achieving the purpose of quickly aligning the through hole 61 with the feeding hopper 34. After alignment, the limiting blade 721 continues to rotate with the drive rod 72 at a relatively slow speed and gradually approaches the straight wall of the relief groove 711. During this process, the solid waste in the processing box 32 has sufficient time to complete the feeding into the incinerator. Only when the limiting blade 721 abuts against the straight wall of the relief groove 711 again can the drive rod 72 continue to drive the sleeve shaft 71 to rotate, thereby causing the rotating circular plate 6 to rotate and driving the through hole 61 to gradually separate from the feeding hopper 34.

[0045] The above settings provide sufficient time for the solid waste in the treatment box 32 to be discharged and meet the intermittent opening and closing requirements of the feeding hopper 34, thus achieving better performance.

[0046] Furthermore, an inclined ring 611 is formed around the through hole 61. The inner diameter of the upper end of the inclined ring 611 is larger than the inner diameter of the lower end of the inclined ring 611, and the included angle between the inclined ring 611 and the bottom surface of the rotating circular plate 6 is less than 45°. This facilitates the smooth passage of solid waste through the through hole 61 and makes it less likely to cause obstruction when the through hole 61 separates from the feeding hopper 34, thus ensuring the smooth rotation of the rotating circular plate 6.

[0047] Furthermore, a lifting bracket 9 is fixed to the upper end of the base 1. A ring frame 91 is fixed to one side of the movable part of the lifting bracket 9. The ring body of the ring frame 91 is fixedly sleeved on the feeding hopper 34, and the ring frame 91 is located below the rotating circular plate 6.

[0048] The front and rear sides of the movable part of the ring frame 91 are integrally formed with reinforcing side frames 92. The reinforcing side frames 92 are fixed to the front and rear sides of the processing box 32. The stability of the processing box 32 and the feeding hopper 34 can be further enhanced by setting up the lifting bracket 9, the ring frame 91 and the reinforcing side frames 92.

[0049] Furthermore, the base 1 is also provided with an installation hole 11 for the feed end of the incinerator to pass through. The installation hole 11 corresponds to the position of the feeding hopper 34 so as to connect the feeding hopper 34 with the feed end of the incinerator.

[0050] The working principle of this utility model is as follows: During daily use, when the rotating shaft of the pusher structure 4 rotates, it drives the drive rod 72 to rotate through the transmission assembly 8. When the drive rod 72 rotates, it abuts against the straight wall of the relief groove 711 through the limiting blade 721, thereby driving the sleeve shaft 71 to rotate. When the sleeve shaft 71 rotates, it drives the rotating circular plate 6 to rotate. During the rotation, when the second magnetic block 62 approaches the first magnetic block 321, the second magnetic block 62 quickly approaches the first magnetic block 321 under the magnetic attraction, and drives the rotating circular plate 6 to rotate faster. Due to the existence of the relief groove 711, the sleeve shaft 71 can rotate at a relatively fast speed, thereby making the straight wall of the relief groove 711 and the limiting blade 721 abut against the straight wall of the relief groove 711. The limiting blade 721 disengages, thereby achieving the purpose of quickly aligning the through hole 61 with the feeding hopper 34. After alignment, the limiting blade 721 continues to rotate with the drive rod 72 at a relatively slow speed and gradually approaches the straight wall of the relief groove 711. During this process, the solid waste in the processing box 32 has sufficient time to complete the feeding into the incinerator. Only when the limiting blade 721 abuts against the straight wall of the relief groove 711 again can the drive rod 72 continue to drive the sleeve shaft 71 to rotate, thereby causing the rotating circular plate 6 to rotate and driving the through hole 61 to gradually separate from the feeding hopper 34, completing one feeding operation into the incinerator. Repeating the above actions can complete intermittent continuous feeding.

[0051] It should be further noted that the technical features such as the feeding structure, crushing disturbance structure, transmission components, and motor involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
