[0002] When CFB boilers are burning, waste is often used for co-combustion. Common waste is sludge. The purpose is to use high temperature to burn out harmful components in the sludge to achieve the standard of reuse. When co-combusting sludge, it is necessary to balance the sludge and fuel, so a proportioning mixing device is needed.

When in use, the sludge and fuel in a predetermined ratio are poured into a mixing barrel, and the stirring blades in the mixing barrel are used to shear and stir the sludge and fuel horizontally to achieve a mixing effect. However, the area that the stirring blades can cover is limited, resulting in some areas in the mixing barrel being unable to be effectively stirred, so that the sludge and fuel in this area cannot be fully mixed, resulting in differences in the amount of fuel adsorbed by the sludge at different depths in the mixing barrel, and pollutants cannot be completely burned during combustion.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0034] See also Figure 1 to Figure 8 In an embodiment of the present invention, a proportioning device for synchronous refinement of sludge feeding for blending and combustion includes: a box body 1, a folding plate group, a traction component, a retardation box 12, a driving component and a blocking structure, which can make a plurality of grooves on the sludge powder layer when the stirring lever 13 moves along the length direction of the loading plate 2, and after the fuel is applied, the fuel is fully absorbed by the sludge near the grooves, and at the same time, when the stirring lever 13 moves in the reverse direction, the number of grooves can be doubled, and the fuel is further absorbed, thereby improving the uniformity of the overall absorption of the fuel by the sludge, thereby ensuring that the pollutants in the sludge are fully removed during combustion, specifically as follows: a guide frame 6 and a loading plate 2 are detachably connected in the box body 1; a crushing mechanism 7 that can move along the length direction of the loading plate 2 is slidably installed on the guide frame 6.

[0035] When in use, the dried sludge is poured into the pulverizing mechanism 7. On the one hand, the pulverizing mechanism 7 can pulverize the hardened sludge to prevent the hardened sludge from being unable to fully absorb the fuel, resulting in incomplete combustion of the sludge and failure to completely remove pollutants. On the other hand, it can reciprocate along the length direction of the loading tray 2, so that the pulverized sludge can be evenly poured into the loading tray 2 and form a sludge powder layer of a certain thickness.

[0036] See also Figure 3 , Figure 5~Figure 6 The stagnation box 12 is arranged on the loading tray 2, and a plurality of stirring levers 13 are equidistantly arranged at the bottom of the stagnation box 12 and are in communication with the stagnation box 12, and discharge ports 1301 are formed on both sides of the stirring levers 13; the driving component is connected to the loading tray 2 and the stagnation box 12, and the driving component can drive the stagnation box 12 to move along the length direction of the loading tray 2, and the driving component can drive the stirring levers 13 to move along the width direction of the loading tray 2; the driving component includes a plurality of stirring levers 13 that are equidistantly arranged at the bottom of the stagnation box 12 and are in communication with the stagnation box 12, and ... Two linear drive modules 8 are set up, and a connecting frame 9 is connected to the linear drive module 8, and the connecting frame 9 is connected to the retardation box 12. Further, the driving assembly also includes a slide groove 901 set on the connecting frame 9, and a sliding connecting block 10 is slidably installed in the slide groove 901, and the sliding connecting block 10 is detachably connected to the retardation box 12; a second electric telescopic rod 11 is also fixedly installed on the connecting frame 9, and the action end of the second electric telescopic rod 11 is connected to the sliding connecting block 10.

[0037] When a sludge powder layer of a certain thickness is formed at the bottom of the loading tray 2, the external oil pumping device is connected to the retention box 12, and the linear drive module 8 and the external oil pumping device are started. At this time, the linear drive module 8 can drive the retention box 12 to move along the length direction of the loading tray 2, and the stirring rod 13 to move along the length direction of the loading tray 2. The stirring rod 13 is used to form several grooves in the sludge powder layer by utilizing the distribution effect. At the same time, the discharge port 1301 at the rear of the movement direction of the stirring rod 13 can release the fuel, so that the fuel can enter the groove and be adsorbed by the two sides and the bottom of the groove, so that the fuel can be fully mixed with the sludge.

[0038] When the stagnation box 12 and the stirring rod 13 move to the end of the stroke, the second electric telescopic rod 11 will drive the sliding connection block 10 to move along the length direction of the slide groove 901, so that the stirring rod 13 can move along the width direction of the loading plate 2. Specifically, the movement distance of the stirring rod 13 is half of the distance between two adjacent stirring rods 13. Then the linear drive module 8 drives the stagnation box 12 and the stirring rod 13 to move in the opposite direction, so that the stirring rod 13 can separate another groove between the two grooves of the sludge powder layer. At the same time, the fuel is absorbed by the sludge through this part of the groove, so that the sludge can fully absorb the fuel.

[0039] Through the above arrangement, when the stirring rod 13 moves along the length direction of the loading plate 2, multiple grooves can be distributed on the sludge powder layer, and after the fuel is applied, the fuel can be fully absorbed by the sludge near the grooves. At the same time, when the stirring rod 13 moves in the reverse direction, the number of grooves can be doubled and the fuel can be further absorbed, thereby improving the uniformity of the overall sludge absorbing the fuel, thereby ensuring that the pollutants in the sludge are fully removed during combustion.

[0040] See also Figure 5~Figure 8 The blocking structure is arranged on the stagnation box 12 and is adapted to the discharge port 1301. A trigger shaft is connected to the blocking structure, and the trigger shaft cooperates with the trigger sleeve connected to the drive assembly to enable the discharge port 1301 located at the rear of the movement direction of the stagnation box 12 to be conductive.

[0041] The blocking structure includes two lifting plates 14 that are sealed and slidably fitted with the side of the stirring lever 13, and a blocking portion 1401 for blocking the discharge port 1301 is formed on the lifting plate 14. A plurality of guide sleeves 16 are also equidistantly arranged on the lifting plate 14, and the guide sleeves 16 are slidably fitted with a vertical shaft 15 arranged on the retardation box 12; the blocking structure also includes a staggered kit connecting the two groups of the lifting plates 14, and the staggered kit can drive the two groups of the lifting plates 14 to move in opposite directions, and the staggered kit includes a rotating rod 18 rotatably mounted on the retardation box 12, and the rotating rod 18 has two symmetrically arranged straight rods arranged along its direction. Groove 1801, the straight groove 1801 is rollingly matched with the second convex shaft 17 rotatably mounted on the end of the lifting plate 14; the trigger shaft includes an insertion shaft 19 coaxially fixedly connected to the rotating shaft of the rotating rod 18, and the side of the insertion shaft 19 is provided with a third convex shaft 1901 adapted to the trigger sleeve, and the trigger sleeve includes a fixed sleeve 20 connected to the connecting frame 9, and the fixed sleeve 20 is provided with a spiral groove 2002, and one end of the spiral groove 2002 is provided with a horizontal groove 2001 extending to the opening of the fixed sleeve 20, and the end of the horizontal groove 2001 away from the spiral groove 2002 is connected with two inclined guide surfaces 2003.

[0042] In the initial state, the stirring lever 13 is at one end of its stroke end, and the rotating rod 18 is in a horizontal state, so that the lifting plates 14 on both sides of the stirring lever 13 are at the same height, so that the blocking portion 1401 is used to block the discharge ports 1301 on both sides of the stirring lever 13. After the sludge powder layer at the bottom of the loading tray 2 is formed, the second electric telescopic rod 11 will move to drive the retardation box 12 to move to the stroke end along the width direction of the loading tray 2. During this process, the insertion shaft 19 on one side of the stirring lever 13 can be inserted into the fixed sleeve 20. At this time, the third convex shaft 1901 can enter the horizontal groove 200 through the guidance of the inclined guide surface 2003. 1, and after moving to the end of the horizontal groove 2001, it enters the spiral groove 2002. At this time, the third convex shaft 1901 cooperates with the spiral groove 2002 to rotate the insertion shaft 19, thereby driving the rotating rod 18 to rotate. The rotating rod 18 cooperates with the second convex shaft 17 through the straight grooves 1801 on both sides thereof, thereby driving the lifting plates 14 on both sides of the stirring lever 13 to rise and fall one by one. Specifically, the lifting plate 14 located at the rear part of the stirring lever 13 in the opposite direction of movement rises. At this time, the discharge port 1301 located at the rear part of the stirring lever 13 in the moving direction is connected to release the fuel, and when the stirring lever 13 moves, the fuel is released into the groove.

[0043] As the stirring lever 13 moves, when it moves to the end of the other end of its stroke, the second electric telescopic rod 11 will move in the reverse direction. At this time, the insertion shaft 19 will be separated from the original fixed sleeve 20, and the two lifting plates 14 will be reset during the separation process to avoid excessive release of fuel in this state. As the second electric telescopic rod 11 moves in the reverse direction, the insertion shaft 19 on the other side of the stirring lever 13 will be inserted into the other fixed sleeve 20, and the rotating rod 18 will continue to rotate, so that the discharge ports 1301 on both sides of the stirring lever 13 can be switched on, so that the discharge ports 1301 located at the rear of the stirring lever 13 moving along the length direction of the loading tray 2 are always in a conducting state.

[0044] The significance of the above arrangement is that if the fuel is released in front of the moving direction of the stirring lever 13, the groove has not yet been formed, and then it will gather in an area of ​​sludge dust, with poor diffusion effect, and it cannot be guaranteed that the sludge can fully and evenly absorb the fuel.

[0045] Through the above-mentioned arrangement, the conduction of the discharge port 1301 can match the movement direction of the stirring rod 13, so that the discharge port 1301 located at the rear of the movement direction of the stirring rod 13 is in a conduction state, thereby releasing fuel into the formed groove, improving the diffusion effect inside the sludge, and further ensuring that the pollutants in the sludge can be fully burned.

[0046] See also Figure 2~Figure 4, the folding plate group is provided with multiple groups and is installed at the bottom of the loading tray 2, the folding plate group has a first posture and a second posture switched by being pulled, when the folding plate group is in the first posture, the multiple groups of folding plate groups can form a supporting plane, when the folding plate group is in the second posture, the bottom of the loading tray 2 can be made conductive, wherein a stop plate 21 is provided at the bottom of the loading tray 2; the folding plate group includes two supporting plates 5 symmetrically rotated and installed at the bottom of the loading tray 2, and one end of the two supporting plates 5 away from the rotation center thereof is connected to the traction assembly; The traction assembly is arranged on the loading tray 2 and connected to the supporting plate 5. The traction assembly includes a plurality of groups of first electric telescopic rods 3 fixedly mounted on the side of the loading tray 2. The action end of the first electric telescopic rod 3 is connected to a driving frame 4, and a transverse groove 401 is arranged on the driving frame 4. A first convex shaft 501 is rotatably mounted on one end of the supporting plate 5 away from its rotation center, and the first convex shaft 501 can roll in the transverse groove 401. When the driving frame 4 moves downward in the vertical direction of the space, the two supporting plates 5 in the same group will be deflected downward.

[0047] Among them, the first posture of the above-mentioned folding plate group is: all the supporting plates 5 remain in a horizontal state to form a supporting plane, so that the sludge powder layer can be highly consistent in the loading plate 2, and when the stirring rod 13 divides the groove, the depth of the groove is consistent, thereby improving the uniformity of the sludge adsorbing the fuel.

[0048] The second posture of the above-mentioned folding plate group is: the two supporting plates 5 in the same group are in a tilted downward state, and at this time, the two corresponding supporting plates 5 of the two adjacent groups can form a funnel-shaped space, so that the sludge and dust after adsorbing the fuel can be separated from the loading plate 2 through the funnel-shaped space. In this process, since the area of ​​the upper part of the funnel-shaped space is larger than the area of ​​the lower part, the sludge and dust have an effect of being gathered when they slide and collapse, thereby having the effect of re-mixing the sludge after adsorbing the fuel.

[0049] It should also be noted that the length direction of the grooves allocated by the stirring rod 13 is perpendicular to the rotation axis of the support plate 5, that is, when the sludge collapses, the sludge adsorbed with the fuel is evenly distributed in the entire collapsed sludge area, so that after secondary mixing in the funnel-shaped space, the fuel can be further mixed with the sludge fully and evenly.

[0050] When the action end of the first electric telescopic rod 3 moves, the driving frame 4 can be driven to perform a lifting action. When the driving frame 4 moves downward, the supporting plate 5 can be deflected downward through the cooperation between the transverse groove 401 and the first protruding shaft 501.

[0051] Through the above arrangement, the supporting plate 5 can have two position states, so that on the one hand, a supporting plane can be formed at the bottom of the loading tray 2, so that the sludge powder layer can be highly consistent in the loading tray 2, and when the stirring rod 13 is used to divide the groove, the depth of the groove is consistent, thereby improving the uniformity of the sludge adsorbing the fuel. On the other hand, the funnel-shaped space formed has the effect of re-mixing the sludge after adsorbing the fuel, thereby further improving the mixing effect of the fuel and the sludge.

[0052] As an embodiment of the present invention, a method for treating sludge using the sludge feeding synchronous refinement type blending and combustion proportioning device is also proposed, comprising the following steps:

[0053] Step 1: pouring the dried sludge into the crushing mechanism 7, which crushes the sludge and evenly pours it into the loading tray 2;

[0054] Step 2: Connect the external oil pumping device to the retardation tank 12 through a pipeline, start the external oil pumping device and start the driving assembly at the same time, the driving assembly can drive the retardation tank 12 to move along the length direction of the loading tray 2 and dump the fuel;

[0055] Step 3: When the retardation box 12 moves to the end of the stroke, the driving assembly controls the retardation box 12 to move along the width direction of the loading plate 2, and the cooperation between the trigger shaft and the trigger sleeve can activate the blocking structure, thereby switching the discharge ports 1301 on both sides of the stirring lever 13;

[0056] Step 4: The driving assembly drives the retardation box 12 to move in the reverse direction, and repeats step 2;

[0057] Step 5: Control the external oil pump device and the driving component to stop working;

[0058] Step 6: The folding plate assembly is driven by the traction assembly to separate the sludge and fuel mixture from the loading tray 2.
