Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a sludge drying and incineration treatment apparatus and method. Background Technology

[0002] Sludge incineration is a sludge treatment process that uses an incinerator to heat and dry dewatered sludge, and then uses high-temperature oxidation to oxidize the organic matter in the sludge, turning the sludge into a small amount of ash. The ash remaining after incineration can be reused as a resource.

[0003] Currently, sludge incineration equipment cannot control the amount of sludge incinerated during operation. If a large amount of sludge needs to be treated, it is commonly practiced to directly feed the dried sludge into the incineration equipment. However, this method suffers from incomplete incineration due to the large volume of sludge, resulting in low incineration efficiency and poor incineration quality. Therefore, we propose a sludge drying and incineration treatment device and method. Summary of the Invention

[0004] The purpose of this invention is to provide a sludge drying and incineration treatment apparatus and method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sludge drying and incineration treatment device, comprising a sludge drying device and an incineration device, wherein the discharge end of the sludge drying device and the feed end of the incineration device are connected through a feed pipe, the incineration device is provided with a burner, and a movably mounted incineration plate is provided above the burner for receiving sludge fed from the feed pipe, the incineration plate is connected to a driving component, which allows the incineration plate to move up and down according to the weight of the sludge, the driving component is located on the incineration device and connected to a sealing assembly, the sealing assembly is located in the inner cavity of the feed pipe, and is driven by the driving component to open the feed pipe when the incineration plate moves upward to a preset position or to close the feed pipe when the incineration plate moves downward to a preset position.

[0006] A further improvement is that the driving component includes a connector connected to the incineration plate. Both ends of the connector are provided with connecting posts. The two sets of connecting posts extend into the two sets of housings and are connected to contact blocks. The two sets of housings are fixed on the incineration equipment and are located on both sides of the feed pipe. The end of the contact block away from the connecting post is connected to the inner wall of the housing through an elastic element. One end of the contact block is connected to a pull rope. The other end of the pull rope movably passes through the top of the inner side of the housing and the feed pipe and is connected to a sealing assembly.

[0007] A further improvement is that the sealing assembly includes rotating shafts respectively rotatably disposed on the inner walls of both sides of the feed pipe. Each of the two sets of rotating shafts has a door body for sealing the feed pipe on its opposite side. Each of the two sets of door bodies is connected to the end of one of two sets of pull ropes away from the contact block. When the incineration plate is downward, the door body is pulled by the pull ropes to flip from an inclined state to a horizontal state. A torsion spring is provided at the connection between the rotating shaft and the inner wall of the feed pipe, which is used to drive the horizontal door body to rotate downward to an inclined state when the incineration plate is upward. Limiting frames are provided on both sides of the inner wall of the feed pipe and above the door body. The end of the limiting frame away from the inner wall of the feed pipe is attached to the top of the door body that has been rotated to the horizontal state.

[0008] A further improvement is that a groove is provided on the outer side of the rotating shaft, and a metal pin is movably provided in the groove through a bracket. The metal pin and the bottom of the groove are connected by an elastic element. A through hole is provided on one side of the inner wall of the housing for inserting the metal pin. An electromagnetic block is fixed in the housing at the position corresponding to the metal pin to attract the metal pin into the through hole. The electromagnetic block is movably sleeved on the outer wall of the connecting column and located below the contact block.

[0009] The upper and lower ends of the contact block are respectively provided with a touch-off button and a touch-on button that are electrically connected to the electromagnetic block. The touch-off button and the touch-on button are both located on the inner wall of the housing. When the contact block contacts the touch-on button, the metal pin is directly aligned with the through hole.

[0010] A further improvement is that the vertical cross-section of the incineration plate is U-shaped, and multiple sets of ash collection holes are provided on the incineration plate;

[0011] The connector includes a rotating shaft rotatably disposed within the incineration plate, the rotating shaft being threaded through two sets of connecting posts.

[0012] A further improvement is that the connector also includes a dispersing blade disposed on the outer wall between the two sets of connecting columns and an elastic element for connecting the connecting columns and the inner wall of the incineration plate.

[0013] A gear is rotatably mounted in one of the housing cavities below the electromagnetic block. A rack meshing with the gear is mounted on a connecting post on one side of the gear. An eccentric wheel is rotatably mounted on the upper side of the incineration plate inside the incineration equipment to drive the incineration plate to move horizontally. The axle of the eccentric wheel and the axle of the gear are connected by a sprocket drive assembly.

[0014] A further improvement is that the incineration equipment has a discharge port at the bottom, and guide rods are horizontally provided at the bottom of the inner walls on both sides of the incineration equipment. A cleaning component for cleaning the inner wall of the bottom of the incineration equipment is slidably provided inside the guide rod. An elastic component four is provided on the outer wall of the guide rod to limit the movement of the cleaning component. Guide roller two and guide roller one are arranged sequentially from the outside to the inside of the inner cavity of the incineration equipment between the inner wall of the side of the incineration equipment and the discharge port. Guide roller two is located above guide roller one. One end of pull rope two is connected to the inner side of the cleaning component. Pull rope two passes around guide roller one and guide roller two and is connected to the fixed section of the telescopic rod. The fixed section of the telescopic rod away from the movable section is slidably connected to the inner wall of the incineration equipment. The movable section of the telescopic rod away from the fixed section is connected to the outer wall of the incineration plate.

[0015] The second pull rope pulls the cleaning component to the discharge port when the incineration plate moves upward.

[0016] A further improvement is that the incineration equipment is equipped with a flue gas discharge pipe, and both the flue gas discharge pipe and the discharge port are equipped with control valves.

[0017] A sludge drying and incineration treatment method, utilizing the above-mentioned treatment device, includes the following steps:

[0018] S1: The sludge is put into the sludge drying equipment for drying treatment. After the sludge is dried, it enters the feed pipe through the discharge end of the sludge drying equipment and falls onto the incineration plate, causing the incineration plate to move downward. When the incineration plate moves downward to the preset position, the driving component drives the sealing assembly to close the feed pipe.

[0019] S2: Turn on the burner to burn the sludge on the incineration plate inside the incineration equipment. As the sludge on the incineration plate burns, the incineration plate gradually rises under the action of the drive component. When the incineration plate rises to the preset position, the drive component drives the sealing door assembly to open the feed pipe, so that the sludge continues to fall onto the incineration plate through the feed pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In this invention, sludge falls onto the incineration plate through a feed pipe, causing the incineration plate to move downwards. When the incineration plate moves downwards to a preset position, a driving component drives a sealing assembly to close the feed pipe. As the sludge on the incineration plate burns, the incineration plate gradually moves upwards under the action of the driving component. When the incineration plate moves upwards to a preset position, the driving component drives the sealing assembly to open the feed pipe, allowing sludge to continue falling onto the incineration plate through the feed pipe. This method controls the amount of sludge fed into the incineration plate, reducing the incineration load on the incineration equipment and avoiding incomplete incineration due to a large amount of sludge, thus improving the incineration effect. On the other hand, it also prevents excessive sludge buildup and blockage inside the incineration equipment. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see the appendix Figure 1

[0029] A sludge drying and incineration treatment device includes a sludge drying device 1 and an incineration device 3. The sludge drying device 1 is a prior art device. When in use, sludge enters from its feed end and is used to dry the sludge.

[0030] The discharge end of the sludge drying equipment 1 and the feed end of the incineration equipment 3 are connected through the feed pipe 2. The incineration equipment 3 is equipped with a burner 4, and a movable incineration plate 5 is provided above the burner 4 to receive the sludge discharged from the feed pipe 2. The burner 4 and the incineration plate 5 are both conventional structures in the existing incineration equipment 3, and will not be described in detail here.

[0031] The incineration plate 5 is connected to a driving component, which allows the incineration plate 5 to move up and down according to the weight of the sludge. Specifically, when the sludge falls onto the incineration plate 5, the incineration plate 5 moves downward under the action of gravity. As the sludge on the incineration plate 5 is gradually burned, the incineration plate 5 gradually moves upward and resets. The driving component is located on the incineration equipment 3 and is connected to a sealing assembly. The sealing assembly is located in the inner cavity of the feed pipe 2. Driven by the driving component, the feed pipe 2 is opened when the incineration plate 5 moves upward to a preset position or closed when the incineration plate 5 moves downward to a preset position. This achieves equal control of sludge feeding and incineration, which on the one hand reduces the incineration load of the incineration equipment and improves the incineration effect of the sludge, and on the other hand prevents sludge accumulation inside the incineration equipment.

[0032] Please see the appendix Figure 2

[0033] Preferably, the driving component in this embodiment includes a connector connected to the incineration plate 5. Both ends of the connector are provided with connecting posts 6. The two sets of connecting posts 6 extend into the two sets of housings 7 and are connected to contact blocks. The two sets of housings 7 are fixed on the incineration equipment 3 and are located on both sides of the feed pipe 2. The end of the contact block away from the connecting post 6 is connected to the inner wall of the housing 7 through an elastic element 8, such as a spring. One end of the contact block is connected to a pull rope 14. The other end of the pull rope 14 passes through the top of the inner side of the housing 7 and the feed pipe 2 and is connected to a sealing assembly. With this arrangement, when the connecting post 6 drives the contact block to move up or down, the sealing assembly can be driven to work through the pull rope 14. In practice, a guide wheel for guiding the pull rope 14 can be embedded in the top of the inner side of the housing 7.

[0034] Preferably, the sealing assembly of this embodiment includes rotating shafts 12 respectively rotatably disposed on the inner walls of both sides of the feed pipe 2. Each of the two sets of rotating shafts 12 has a door body 13 for sealing the feed pipe 2 on its opposite side. When the two sets of door bodies 13 are in a horizontal state, the sludge cannot enter the incineration equipment 3 from the feed pipe 2. The two sets of door bodies 13 are respectively connected to the ends of two sets of pull ropes 14 away from the contact block. When the incineration plate 5 is downward, the door body 13 is pulled by the pull ropes 14 to flip from the inclined state to the horizontal state. A torsion spring is provided at the connection between the rotating shaft 12 and the inner wall of the feed pipe 2 to drive the horizontal door body 13 to rotate downward to the inclined state. Limiting frames 15 are provided on both sides of the inner wall of the feed pipe 2 and above the door body 13. The limiting frames 15 are L-shaped. The end of the limiting frame 15 away from the inner wall of the feed pipe 2 is attached to the top of the door body 13 when it is rotated to the horizontal state to prevent the door body 13 from over-flipping.

[0035] Preferably, the outer side of the rotating shaft 12 in this embodiment has a groove, and a metal pin 16 is movably mounted in the groove via a bracket. The metal pin 16 and the bottom of the groove are connected by an elastic element 17, such as a spring. One inner wall of the housing 7 has a through hole for inserting the metal pin 16. Inserting the metal pin 16 into the through hole keeps the door 13 in a stable horizontal state, preventing the door 13 from being flipped downwards due to the sludge in the sludge drying equipment 1. An electromagnetic block 11 is fixedly mounted in the housing 7 at the position corresponding to the metal pin 16, which is electrically attracted to the metal pin 16 into the through hole. The electromagnetic block 11 is movably sleeved on the outer wall of the connecting column 6 and located below the contact block. When the door 13 is rotated to a horizontal state, the metal pin 16 corresponds to the through hole, and the electromagnetic block 11 is electrically attracted to the metal pin 16 into the through hole, thereby fixing the state of the door 13.

[0036] The upper and lower ends of the contact block are respectively provided with a touch-off button 9 and a touch-on button 10 that are electrically connected to the electromagnetic block 11. The touch-off button 9 and the touch-on button 10 are both located on the inner wall of the housing 7. When the contact block contacts the touch-on button 10, the metal pin 16 corresponds to the through hole, that is, the door 13 is in a horizontal state at this time.

[0037] Preferably, the incineration plate 5 in this embodiment has a U-shaped vertical cross section, and multiple sets of ash dropping holes are provided on the incineration plate 5 so that the products formed by the incineration of sludge on the incineration plate 5 fall downwards.

[0038] The connecting component includes a rotating shaft 18 rotatably disposed within the incineration plate 5. The rotating shaft 18 is threaded through two sets of connecting posts 6. With this arrangement, the rotating shaft 18 moves when the incineration plate 5 moves, and the rotating shaft 18 also rotates under the action of the thread when it moves.

[0039] Preferably, the connector in this embodiment also includes a dispersing blade 19 disposed on the outer wall between the two sets of connecting columns 6 and an elastic element 20 for connecting the connecting column 6 and the inner wall of the incineration plate 5. The elastic element 20, such as a spring, is used to drive the incineration plate 5 to move. By moving through the rotating shaft 18 and driving the dispersing blade 19 to rotate, the sludge falling onto the incineration plate 5 can be dispersed to improve the incineration effect of the sludge.

[0040] A gear 21 is rotatably mounted inside the housing 7 and below the electromagnetic block 11. A rack meshing with the gear 21 is mounted on the connecting column 6 on one side of the gear 21. An eccentric wheel 22 is eccentrically mounted on the upper side of the incineration plate 5 inside the incineration device 3 to drive the incineration plate 5 to move horizontally. The axle of the eccentric wheel 22 and the axle of the gear 21 are connected by a sprocket drive assembly, which includes a sprocket and a chain. When the connecting column 6 moves, the gear 21 is driven by the rack. The gear 21 drives the eccentric wheel 22 to rotate through the sprocket drive assembly. The eccentric rotation of the eccentric wheel 22 intermittently pushes the incineration plate 5 to move horizontally, causing the incineration plate 5 to vibrate. This makes the sludge falling on the incineration plate 5 evenly distributed on the incineration plate 5, improving the sludge incineration effect and also facilitating the downward fall of the products obtained after sludge incineration.

[0041] It should be noted that when the incineration plate 5 is moved up and down to any position, the eccentric wheel 22 can contact the side wall of the incineration plate 5.

[0042] Please see the appendix Figure 3

[0043] Preferably, the incineration device 3 in this embodiment has a discharge port at its bottom. Guide rods 24 are horizontally arranged at the bottom of the inner walls on both sides of the incineration device 3. A cleaning component 25 for cleaning the inner wall of the bottom of the incineration device 3 is slidably arranged inside the guide rods 24. The guide rods 24 have a T-shaped vertical section, which moves and guides the cleaning component 25. The cleaning component 25 is, for example, a cleaning brush. An elastic element four, for example, a spring, is provided on the outer wall of the guide rods 24 to limit the movement of the cleaning component 25, thereby driving the moving cleaning brush to reset. Guide rollers 27 and 26 are arranged sequentially from the outside to the inside of the inner cavity of the incineration device 3 between the inner wall of the side and the discharge port. Both guide roller 27 and guide roller 26 are existing technologies, including shafts and guide rollers. Guide roller 27 is located above guide roller 26. One end of pull rope 28 is connected to the inner side of cleaning component 25. Pull rope 28 passes around guide roller 26 and guide roller 27 and is connected to the fixed section of telescopic rod 29. The fixed section of telescopic rod 29 is slidably connected to the inner wall of incineration equipment 3 at the end away from the movable section. Telescopic rod 29 includes a fixed section and a movable section inserted into one end of the fixed section, which is existing technology. The movable section of telescopic rod 29 is connected to the outer wall of incineration plate 5 at the end away from the fixed section. Pull rope 28 pulls cleaning component 25 to the discharge port when incineration plate 5 moves upward. With this setup, when the incineration plate 5 moves upward, the fixed section of the telescopic rod 29 pulls the second pull rope 28, causing the second pull rope 28 to pull the cleaning component 25 along the guide rod 24, cleaning the sludge incineration products that fall on the inner wall of the incineration equipment 3 to the discharge port. The fixed section connecting the second pull rope 28 ensures that the second pull rope 28 is not affected by the horizontal movement of the incineration plate 5.

[0044] Preferably, the incineration equipment 3 in this embodiment is provided with a flue gas discharge pipe 30, and both the flue gas discharge pipe 30 and the discharge port are provided with control valves 23 to control the opening and closing of flue gas discharge or the opening and closing of sludge incineration product discharge.

[0045] A sludge drying and incineration treatment method, utilizing the above-mentioned treatment device, includes the following steps:

[0046] S1: The sludge is put into the sludge drying equipment 1 for drying treatment. After the sludge is dried, it enters the feed pipe 2 through the discharge end of the sludge drying equipment 1 and falls onto the incineration plate 5, causing the incineration plate 5 to move downward. When the incineration plate 5 moves downward to the preset position, the driving component drives the sealing assembly to close the feed pipe 2.

[0047] S2: Turn on the burner 4 to burn the sludge on the incineration plate 5 in the incineration equipment 3. As the sludge on the incineration plate 5 burns, the incineration plate 5 gradually moves upward under the action of the drive component. When the incineration plate 5 moves upward to the preset position, the drive component drives the sealing door assembly to open the feed pipe 2, so that the sludge continues to fall onto the incineration plate 5 through the feed pipe 2.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
