DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] During use of this scheme, the fluidized sludge enters the filter frame 3 through the feed pipe 4, and the filter frame 3 filters the impurities therein to separate the fluidized sludge from the impurities, causing the fluidized sludge to fall and flow to the two sides of the dehydration frame 1, and under the heating of the electric heating plate 12, the detachable fiber filter press plate 5 made of a mixture of synthetic fibers and plates drives the sludge to separate from the water phase and dehydrate and solidify. After the dehydration and solidification is completed, the detachable fiber filter press plate 5 is a detachable threaded connection method, which is common knowledge known in the prior art. Therefore, based on the known basis, it is not described in detail in this scheme, and the detachable fiber filter press plate 5 is removed to discharge the dehydrated and solidified sludge.

[0035] like Figure 1-Figure 2 As shown, the filtering toggle mechanism 7 includes a pair of detachable impurity filtering plates 701, and the pair of detachable impurity filtering plates 701 are respectively fixedly connected to the inner walls of a pair of filter frames 3, a rotating rod 702 is rotatably connected between the pair of filter frames 3 and a pair of mounting plates 6 through a bearing, and the outer walls of the pair of rotating rods 702 are fixedly connected with a plurality of evenly distributed toggle rods 703, one end of the mounting plate 6 located on one side is fixedly connected with a supporting plate 705, and the top of the supporting plate 705 is fixedly connected with a rotating motor 704, the output end of the rotating motor 704 is fixedly connected to the rotating rod 702 located on one side, the outer walls of the pair of rotating rods 702 are sleeved with pulleys 706, and a transmission belt 707 is meshed and connected between the outer walls of the pair of pulleys 706.

[0036] During use of this solution, after the fluid sludge enters the filter frame 3 through the feed pipe 4, it flows downward along the inclined surface of the filter frame 3 and is filtered by the removable impurity filter plate 701 to separate the fluid sludge from the impurities therein. At the same time, the rotating motor 704 drives a pair of rotating rods 702 to rotate through the synchronous transmission action between a pair of pulleys 706 and a transmission belt 707, so that it drives multiple toggle rods 703 to rotate, to toggle the fluid sludge attached to the removable impurity filter plate 701, to reduce the possibility of blockage, and to promote the fluid sludge to flow quickly downward into the dehydration frame 1 to avoid interference with subsequent dehydration and solidification.

[0037] like Figure 1 and Figure 3 as well as Figure 6 As shown, the magnetic repulsion collision mechanism 8 includes a first magnet block 801 fixedly connected to the outer wall of the transmission belt 707, one end of the dehydration frame 1 is fixedly connected to a U-shaped plate 804, and one end of the dehydration frame 1 is provided with a plurality of collision hemispheres 808, and the ends of the plurality of collision hemispheres 808 away from the dehydration frame 1 are all fixedly connected to a movable rod 806, the inner wall of the U-shaped plate 804 is drilled with a plurality of circular holes, and the ends of the plurality of movable rods 806 away from the dehydration frame 1 pass through the circular holes and are fixedly connected to a second magnet block 805, and the first magnet block 801 and the second magnet block 805 repel each other at their adjacent ends. The outer walls of the plurality of movable rods 806 are all sleeved with a first spring 807, and the two ends of the first spring 807 are respectively fixedly connected to the inner wall of the U-shaped plate 804 and one end of the collision hemisphere 808, the first magnet block 801 is fixedly connected to the sliding rod 802 at one end close to the dehydration frame 1, a slide groove 803 is drilled at one end of the dehydration frame 1, and one end of the sliding rod 802 is located in the slide groove 803 and is slidably connected thereto, the first magnet block 801 and the second magnet block 805 are both single-sided magnet blocks, and the ends of the first magnet block 801 and the second magnet block 805 that are close to each other are both magnetic ends.

[0038] During use of the present solution, during the movement of the transmission belt 707, the first magnet block 801 is driven to move synchronously along the slide groove 803 with the assistance of the sliding rod 802. During the movement of the first magnet block 801, it corresponds to multiple second magnet blocks 805 in turn, so that the two are in a repulsive state. The second magnet block 805 is driven to move with the help of the magnetic repulsive force, so that it drives the movable rod 806 and the collision hemisphere 808 to separate from the dehydration frame 1, and compresses the first spring 807. After the first magnet block 801 and the second magnet block 805 move away from each other, the magnetic repulsive force gradually weakens to disappear. At this time, under the elastic action of the first spring 807, the movable rod 806, the collision hemisphere 808 and the second magnet block 805 are driven to reset, prompting the collision hemisphere 808 to contact and collide with the dehydration frame 1. This is repeated to generate vibration, thereby achieving the shaking off of the sludge attached to the inner wall of the dehydration frame 1 for subsequent extrusion and dehydration treatment.

[0039] like Figure 1 and Figure 4 As shown, the extrusion and collision mechanism 9 includes a pair of eccentric wheels 901, and the pair of eccentric wheels 901 are respectively sleeved on the outer walls of a pair of rotating rods 702, and the other end of the dehydration frame 1 is fixedly connected with two pairs of auxiliary telescopic rods 904, and a movable straight plate 903 is fixedly connected between one ends of the pair of auxiliary telescopic rods 904, and the outer walls of the pair of auxiliary telescopic rods 904 are sleeved with second springs 905, and the two ends of the second spring 905 are respectively fixedly connected to the auxiliary telescopic rods 904 and one end of the movable straight plate 903, and the end of the movable straight plate 903 close to the auxiliary telescopic rod 904 is respectively fixedly connected with a circular plate 902 and a pair of collision cams 906, the outer wall of the circular plate 902 is in contact with the outer wall of the eccentric wheel 901, and the outer walls of the pair of collision cams 906 are in contact with the outer wall of the dehydration frame 1.

[0040] During use of the present scheme, when a pair of rotating rods 702 rotate, a pair of eccentric wheels 901 are driven to rotate synchronously. During the rotation of the pair of eccentric wheels 901, the eccentric ends thereof contact the circular plate 902, and squeeze the circular plate 902 and the movable straight plate 903 to move with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving a pair of collision protrusions 906 to separate from the dehydration frame 1. After the eccentric ends of the eccentric wheels 901 are separated from the circular plate 902, the circular plate 902 and the movable straight plate 903 that have lost squeezing are reset again with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving a pair of collision protrusions 906 to contact and collide with the dehydration frame 1, and this process is repeated to generate vibration, thereby shaking off the sludge attached to the inner wall of the dehydration frame 1 and the surface of the detachable fiber filter press plate 5, reducing the possibility of blockage, and facilitating the extrusion and dehydration process.

[0041] like Figure 1 and Figure 5 As shown, the auxiliary heating mechanism 10 includes a pair of I-shaped rods 1001, the pair of I-shaped rods 1001 are fixedly connected to the top of the mounting plate 6, the outer walls of the pair of I-shaped rods 1001 are sleeved with a pair of movable sleeve plates 1005, and a telescopic heat reflection film 1003 is fixedly connected between the pair of I-shaped rods 1001 and the two movable sleeve plates 1005 in the vertical direction, and the outer walls of the pair of I-shaped rods 1001 are sleeved with two pairs of deformation memory springs 1004, and the deformation memory springs 1004 The two ends are respectively fixedly connected to the inside of the I-shaped rod 1001 and one end of the movable sleeve 1005, the deformation memory spring 1004 is made of shape memory alloy material, and the initial state of the deformation memory spring 1004 is a contracted state, a pair of I-shaped rods 1001 are fixedly connected between the outer walls with a connecting top plate 1002, and the two ends of the connecting top plate 1002 are fixedly connected with a fixed straight plate 1006, and the outer walls of a pair of fixed straight plates 1006 are fixedly connected with an air blowing fan 1007.

[0042] During use of the present solution, the electric heating plate 12 is heated to release heat, thereby increasing the temperature inside the dehydration frame 1 and dehydrating and drying the fluidized sludge. At the same time, as the heated hot air flows upward, the deformation memory spring 1004 made of shape memory alloy material is deformed when heated and extends, driving the telescopic heat reflective film 1003 made of special heat reflective resin material to extend and reflect heat. A pair of air fans 1007 blow air downward, which can drive the upward-flowing hot air to flow downward under the blowing action, thereby reducing the leakage and loss of heat, and allowing the heat to fully stay inside the dehydration frame 1, driving the heat to be fully utilized in the dehydration and drying process of the fluidized sludge, thereby reducing the waste of resources and enhancing the drying and dehydration effect.

[0043] like Figure 1 and Figure 7-Figure 8 As shown, the extrusion dehydration mechanism 11 includes a pair of cams 1101, the top ends of the pair of cams 1101 are respectively fixedly connected to the bottom ends of a pair of air blowing fans 1007, the inner wall of the dehydration frame 1 is provided with a pair of heat-conducting extrusion plates 1103 in close contact therewith, and the electric heating plate 12 is fixedly connected to one end of the heat-conducting extrusion plate 1103, the ends of the pair of heat-conducting extrusion plates 1103 that are close to each other are fixedly connected to a connecting side plate 1102, and one end of the connecting side plate 1102 is in contact with one end of the cam 1101, and the ends of the pair of heat-conducting extrusion plates 1103 that are far away from each other are fixedly connected to a plurality of evenly distributed knocking hammer rods 1104, and the dehydration frame 1 Two pairs of built-in straight cylinders 1105 are provided inside, and a pair of built-in straight cylinders 1105 are fixedly connected to the inner bottom end of the dehydration frame 1 through vertical rods, the inner walls of the pair of built-in straight cylinders 1105 are slidably connected with a pair of T-shaped slide bars 1106, and the inner walls of the pair of built-in straight cylinders 1105 are drilled with through holes, the outer walls of the pair of T-shaped slide bars 1106 are sleeved with spring tubes 1107, and the two ends of the spring tubes 1107 are respectively fixedly connected to the inner walls of the built-in straight cylinders 1105 and one end of the T-shaped slide bars 1106, the ends of the pair of T-shaped slide bars 1106 that are far away from each other pass through the through holes and are respectively fixedly connected to the ends close to the heat-conducting extrusion plate 1103.

[0044] During use of the present solution, a pair of air blowing fans 1007 rotate, driving a pair of cams 1101 to rotate, so that during the rotation process, the pair of cams 1101 drive their raised ends to squeeze repeatedly. A pair of heat-conducting extrusion plates 1103 move apart with the assistance of the T-shaped slide bar 1106 and the spring tube 1107, so that the pair of heat-conducting extrusion plates 1103 squeeze the fluid sludge on both sides, so that the residual water in the fluid sludge can be separated under the extrusion action, thereby accelerating the dehydration and solidification efficiency of the fluid sludge. At the same time, multiple knocking hammers 1104 move synchronously with the heat-conducting extrusion plates 1103, and repeatedly contact and collide with one end of the filter frame 3 to generate vibration, so as to assist the filtration of the detachable impurity filter plate 701 with vibration, so that the sludge attached to the filtration of the detachable impurity filter plate 701 is loosened under the action of vibration, which is convenient for the sludge to fall and be discharged.

[0045] A municipal sludge dehydration and solidification method comprises the following steps:

[0046] S1. First, the fluid sludge enters the filter frame 3 through the feed pipe 4, and the impurities in the fluid sludge are filtered and separated by the detachable impurity filter plate 701 in the filter toggle mechanism 7, so that the fluid sludge falls into the dewatering frame 1;

[0047] S2, after the fluidized sludge falls into the dehydration frame 1, a pair of electric heating plates 12 work to release heat, and the auxiliary heating mechanism 10 drives the heat to flow to the fluidized sludge to heat and dehydrate it;

[0048] S3. During the heating and dehydration process of the fluidized sludge, the extrusion dehydration mechanism 11, with the assistance of the vibration of the magnetic repulsion collision mechanism 8 and the extrusion collision mechanism 9, repeatedly separates and squeezes the fluidized sludge on both sides to perform extrusion dehydration, so that water flows out through the detachable fiber filter press plate 5, driving the fluidized sludge to be dehydrated and solidified under the heating and extrusion treatment, and converted into semi-solid or solid mud blocks. Then, the detachable fiber filter press plate 5 is disassembled, driving the semi-solid or solid mud blocks to be discharged, and at the same time, the detachable impurity filter plate 701 is disassembled, driving the impurities to be discharged.

[0049] The present invention provides a municipal sludge dehydration and solidification method and device thereof. The working principle is as follows: the fluidized sludge enters the filter frame 3 through the feed pipe 4, flows downward along the inclined surface of the filter frame 3, and is filtered by the detachable impurity filter plate 701, so that the fluidized sludge is separated from the impurities therein. At the same time, the rotating motor 704 drives a pair of rotating rods 702 to rotate through the synchronous transmission action between a pair of pulleys 706 and a transmission belt 707, so that it drives a plurality of toggle rods 703 to rotate, to toggle the fluidized sludge attached to the detachable impurity filter plate 701, and promote the fluidized sludge to flow downward quickly and be diverted to the two sides inside the dehydration frame 1. At this time, the electric heating plate 12 is heated to release heat, so that the temperature inside the dehydration frame 1 is increased, and the fluidized sludge is dehydrated and dried. At the same time, as the heated hot air flows upward, the deformation memory spring 1004 is deformed by heat and extends, driving the telescopic heat reflection film 1003 to extend, which can reflect the heat, and a pair of air blowing fans 1007 blow air downward, which can drive the hot air flowing upward to flow downward under the blowing action, so that the heat is fully retained in the dehydration frame 1, and the heat is fully utilized in the dehydration and drying process of the fluidized sludge. The corresponding pair of air blowing fans 1007 rotate, driving the pair of cams 1101 to rotate, so that the pair of cams 1101 drive their raised ends to squeeze repeatedly during the rotation process. A pair of heat-conducting extrusion plates 1103 move apart with the assistance of the T-shaped slide bar 1106 and the spring tube 1107, so that a pair of heat-conducting extrusion plates 1103 are pressed against the two The fluid sludge on the side is squeezed so that the residual water in the fluid sludge can be separated under the squeezing action and discharged outward through the detachable fiber filter press plate 5. At the same time, multiple hammer rods 1104 move synchronously with the heat-conducting squeezing plate 1103, and repeatedly contact and collide with one end of the filter frame 3 to generate vibration, so as to assist the filtration of the detachable impurity filter plate 701 with vibration, so that the sludge attached to the filtration of the detachable impurity filter plate 701 is loosened under the action of vibration, and is separated from the detachable impurity filter plate 701 and falls off. In addition, during the movement of the transmission belt 707, the first magnet block 801 is driven to move synchronously along the slide groove 803 with the assistance of the sliding rod 802. During the movement of the first magnet block 801, it sequentially contacts with multiple second magnet blocks 801. 05 corresponds to each other, so that the two are in a repulsive state, and the second magnet block 805 is driven to move by means of the magnetic repulsive force, so that it drives the movable rod 806 and the collision hemisphere 808 to separate from the dehydration frame 1, and compresses the first spring 807. After the first magnet block 801 and the second magnet block 805 are separated, the magnetic repulsive force gradually weakens and disappears. At this time, under the elastic action of the first spring 807, the movable rod 806, the collision hemisphere 808 and the second magnet block 805 are driven to reset, causing the collision hemisphere 808 to contact and collide with the dehydration frame 1, and this is repeated to generate vibration, and the silt attached to the inner wall of the dehydration frame 1 is shaken off. Correspondingly, when the pair of rotating rods 702 rotate, the pair of eccentric wheels 901 are driven to rotate synchronously. During the rotation of the pair of eccentric wheels 901,Its eccentric end contacts the circular plate 902, and squeezes the circular plate 902 and the movable straight plate 903 to move with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving a pair of collision convex rods 906 to separate from the dewatering frame 1. After the eccentric end of the eccentric wheel 901 separates from the circular plate 902, the circular plate 902 and the movable straight plate 903 that lose squeezing are reset again with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving a pair of collision convex rods 906 to contact and collide with the dewatering frame 1, and this is repeated to generate vibration, further shaking off the sludge attached to the inner wall of the dewatering frame 1 and the surface of the detachable fiber filter press plate 5, reducing the possibility of blockage, and promoting the sludge to be fully squeezed and dehydrated.
