DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figures 1-8 As shown, a municipal sludge dewatering and solidification method and device thereof include a dewatering frame 1, the bottom end of the dewatering frame 1 is fixedly connected to two pairs of support rods 2, and the top of the dewatering frame 1 is fixedly connected to a pair of filter frames 3, the ends of the pair of filter frames 3 away from each other are fixedly connected to a feed pipe 4, both ends of the dewatering frame 1 are embedded with detachable fiber filter plates 5, and the top of the dewatering frame 1 is fixedly connected to a pair of mounting plates 6, a filter toggle mechanism 7 is provided between the interior of the filter frame 3 and the outer wall of the mounting plate 6, and a magnetic repulsion collision mechanism 8 and an extrusion collision mechanism 9 are respectively provided between the outer walls of the pair of mounting plates 6 and the two ends of the dewatering frame 1, a pair of electric heating plates 12 are provided inside the dewatering frame 1, and an extrusion dewatering mechanism 11 is provided inside the dewatering frame 1, and an auxiliary heating mechanism 10 is provided between the tops of the pair of mounting plates 6.

[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 be diverted to both sides of the dehydration frame 1. 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 be dehydrated and solidified. 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 filter plates 701, and the pair of detachable impurity filter plates 701 are respectively fixedly connected to the inner walls of a pair of filter frames 3, and a rotating rod 702 is rotatably connected between the pair of filter frames 3 and the pair of mounting plates 6 through a bearing. The outer walls of the pair of rotating rods 702 are fixedly connected with a plurality of evenly distributed toggle rods 703, and 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, and the output end of the rotating motor 704 is fixedly connected to the rotating rod 702 located on one side, and the outer walls of the pair of rotating rods 702 are both sleeved with pulleys 706, and the outer walls of the pair of pulleys 706 are meshed with a transmission belt 707.

[0036] During use of this solution, after the fluidized 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 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 multiple toggle rods 703 to rotate, to toggle the fluidized sludge attached to the detachable impurity filter plate 701, thereby reducing the possibility of blockage and prompting the fluidized 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, a U-shaped plate 804 fixedly connected to one end of the dehydration frame 1, and a plurality of collision hemispheres 808 are provided at one end of the dehydration frame 1, and the ends of the plurality of collision hemispheres 808 away from the dehydration frame 1 are fixedly connected to a movable rod 806, the inner wall of the U-shaped plate 804 is bored 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 the second magnet block 805, and the first magnet block 801 and the second magnet block 805 repel each other at their respective ends. The outer walls of multiple movable rods 806 are all sleeved with first springs 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 sliding groove 803 is carved at one end of the dehydration frame 1, and one end of the sliding rod 802 is located in the sliding groove 803 and is slidably connected to it. 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 this solution, when the transmission belt 707 moves, it drives the first magnet block 801 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 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 away from each other, 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. This is repeated to generate vibration, thereby shaking off the sludge attached to the inner wall of the dehydration frame 1 for subsequent extrusion and dehydration processing.

[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. 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 end of a pair of auxiliary telescopic rods 904. The outer walls of the pair of auxiliary telescopic rods 904 are sleeved with a second spring 905, and the two ends of the second spring 905 are respectively fixedly connected to the auxiliary telescopic rod 904 and one end of the movable straight plate 903. 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 protrusions 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 protrusions 906 are in contact with the outer wall of the dehydration frame 1.

[0040] During use of this solution, when a pair of rotating rods 702 rotate, the pair of eccentric wheels 901 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 the 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 their squeezing are reset again with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving the pair of collision protrusions 906 to contact and collide with the dehydration frame 1, and so on. Vibration is generated, which shakes off the silt 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, so as to facilitate the extrusion dehydration process.

[0041] like Figure 1 and Figure 5 As shown, the auxiliary heating mechanism 10 includes a pair of I-shaped rods 1001, each of which is fixedly connected to the top of the mounting plate 6, and the outer walls of the pair of I-shaped rods 1001 are each sleeved with a pair of movable sleeves 1005, and a telescopic heat reflecting film 1003 is fixedly connected between the pair of I-shaped rods 1001 and the two movable sleeves 1005 in the vertical direction, and the outer walls of the pair of I-shaped rods 1001 are each 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 connecting top plate 1002 is fixedly connected between the outer walls of a pair of I-shaped rods 1001, and both ends of the connecting top plate 1002 are fixedly connected to a fixed straight plate 1006, and the outer walls of a pair of fixed straight plates 1006 are fixedly connected to an air blowing fan 1007.

[0042] During use of this solution, the electric heating plate 12 heats up and releases 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 and extended when heated, driving the telescopic heat reflective film 1003 made of special heat reflective resin material to extend and reflect heat. A pair of air blowing fans 1007 blow air downward, which can drive the upward-flowing hot air to flow downward under the blowing action, reducing heat leakage and loss, and prompting the heat to fully stay inside the dehydration frame 1, driving the heat to be fully utilized in the dehydration and drying treatment of the fluidized sludge, reducing resource waste, 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 fixedly connected to the bottom ends of a pair of air blowing fans 1007 respectively, 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 the 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 away from each other are fixedly connected to a plurality of evenly distributed knocking hammer rods 1104, 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, and the inner walls of the pair of built-in straight cylinders 1105 are slidably connected to a pair of T-shaped slides 1106, and the inner walls of the pair of built-in straight cylinders 1105 are drilled with through holes, and the outer walls of the pair of T-shaped slides 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 1106, and the ends of the pair of T-shaped slides 1106 that are away from each other pass through the through holes and are respectively fixedly connected to the end close to the heat-conducting extrusion plate 1103.

[0044] During use of this solution, a pair of air blowing fans 1007 rotate, driving a pair of cams 1101 to rotate, so that during the rotation, 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 hammer rods 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 facilitate vibration-assisted filtration of the detachable impurity filter plate 701, so that the sludge attached to the filtration of the detachable impurity filter plate 701 is loosened under the action of vibration, which facilitates the falling and discharge of the sludge.

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

[0046] S1. First, the fluidized sludge enters the filter frame 3 through the feed pipe 4. The impurities in the fluidized sludge are filtered and separated by the detachable impurity filter plate 701 in the filter toggle mechanism 7, and the fluidized 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, heating and dehydrating it;

[0048] S3. During the heating and dehydration process of the fluidized sludge, the extrusion and dehydration mechanism 11, with the assistance of the vibration of the magnetic repulsion and collision mechanism 8 and the extrusion and collision mechanism 9, repeatedly squeezes the fluidized sludge on both sides to perform extrusion and 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 multiple 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 both sides of the dehydration frame 1. At this time, the electric heating plate 12 is heated and releases heat, so that the temperature inside the dehydration frame 1 is increased, and the fluidized sludge is dehydrated and dried. The hot air flows upward, and at the same time, as the heated hot air flows upward, the deformation memory spring 1004 is deformed by the heat and extends, driving the telescopic heat reflecting film 1003 to extend, which can reflect the heat, and the 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 convex 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 knocking hammers 1104 move synchronously with the heat-conducting extrusion 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 falls off from the detachable impurity filter plate 701. 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 contacts with multiple second magnet blocks 801 in turn. 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 away from each other, 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 so on and so forth, generating vibration, and shaking off the silt attached to the inner wall of the dehydration frame 1. 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 the pair of collision protrusions 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, which have lost their squeezing, are reset again with the assistance of the auxiliary telescopic rod 904 and the second spring 905, driving the pair of collision protrusions 906 to contact and collide with the dewatering frame 1. This process is repeated, generating vibration, which further shakes off the sludge adhering 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 ensuring that the sludge is fully squeezed and dehydrated.
