[0015] Compared with the prior art, the present invention provides an environmentally friendly water conservancy project sludge treatment equipment, which has the following beneficial effects: 1. In life, sludge is divided into two types, one is wet sludge containing water, and the other is dry sludge. The present invention goes through two steps when treating wet sludge or dry sludge. The first step is pretreatment, and the second step is to make biomass pellet fuel, thereby achieving harmless treatment of sludge, being more environmentally friendly, and being able to replace traditional fuels.

[0016] 2. Since there are two groups of ring die holes on each ring die, each adjacent two ring die are connected by threads, and the sizes of the ring die holes on each group of ring die can be the same or different. They can be set according to the needs of the staff, so that biomass pellet fuels of different sizes can be well produced.

[0017] 3. During extrusion granulation, since only one set of ring die hole groups is needed, before opening the valve, the second lifting mechanism is first used to make the height of the heating plate and the grinding disc match the height of a certain set of ring die hole groups to be used. Secondly, the first lifting mechanism is used to drive the movable cover to move so that the inner cylinder of the movable cover covers all other ring die hole groups above the ring die hole group. The purpose of this is to prevent the sludge and sawdust from falling through the ring die holes and splashing to the outside of the ring die after the valve is opened, thereby avoiding the waste of raw materials and the flying of raw materials under the action of the grinding disc during the granulation process, but they will not splash to the outside of the ring die.

[0018] 4. During the extrusion granulation process, if the ring die hole is blocked, the cleaning mechanism can clear the blockage. In addition, if the ring die hole group is damaged, it is necessary to replace other ring die hole groups with the same aperture size, which can be achieved by the cooperation of the second lifting mechanism and the first lifting mechanism. If all the ring die hole groups are damaged and need to be replaced, the second lifting mechanism is used to lower the heating plate into the bottom cylinder for storage, and then all the ring die parts are disassembled. The purpose of this is to prevent the raw materials on the heating plate from falling off the heating plate when there is no ring die "circle", which meets the needs of the staff.

Example 2

[0023] Please refer to Figure 1-Figure 9As shown, two groups of fixed plates 113 are fixedly connected to the top of the movable cover 103, and a second driving motor 115 for driving the processing box 114 to rotate is arranged on the outer side of one group of fixed plates 113, and a first bucket body 119 and a second bucket body 122 are respectively installed on both sides of the bottom of the processing box 114, a filter plate 116 is installed on the top of the first bucket body 119, and a valve 123 is arranged at the bottom of the second bucket body 122, and the bottom of the first bucket body 119 is connected to a water outlet pipe 120, and a pressure plate 118 is slidably connected to the side of one group of partitions 121, and a cylinder 117 is installed on the top of the processing box 114, and the middle part of the top end of the pressure plate 118 is fixedly connected to the output end of the cylinder 117, and a first feed port 124 and a second feed port 125 are also arranged on the top of the processing box 114.

[0024] It can be understood by those skilled in the art that the internal space of the treatment box 114 is divided into three parts by providing two sets of partitions 121. In life, sludge is divided into two types, one is wet sludge containing water, and the other is dry sludge. The present invention requires pretreatment when treating wet sludge or dry sludge. If wet sludge containing water is pretreated, first, the two groups of partitions 121 are completely inserted into the processing box 114, wet sludge is added through the first feed port 124, and then flocculant is added to the first feed port 124. The output end of the second drive motor 115 reciprocates to drive the left end of the processing box 114 to tilt upward and downward, which has a shock effect, so that the wet sludge and the flocculant are fully in contact. Secondly, the partition 121 close to the filter plate 116 moves upward, and then the processing box 114 is driven to be tilted through the output end of the second drive motor 115, so that the sludge treated with the flocculant all enters the top of the filter plate 116. After that, the partition 121 close to the filter plate 116 moves upward. The second bucket 122 is provided with a plurality of partitions 121, which are arranged to move downward to reset, and then the pressure plate 118 is driven downward by the output end of the cylinder 117 to squeeze the sludge, squeeze out the water in the sludge, and discharge it into the external water pool through the outlet pipe 120. Finally, the two groups of partitions 121 all move upward, and the processing box 114 is driven to be tilted by the output end of the second drive motor 115, so that the sludge after the filter press slides into the inside of the second bucket 122. Then, the two groups of partitions 121 all move downward to reset, and the crushed wood chips are introduced into the second feed port 125. Finally, the left end of the processing box 114 is driven to tilt upward and downward by the reciprocating rotation of the output end of the second drive motor 115, so that the sludge and the wood chips are fully mixed. When pre-treating dry sludge, the two sets of partitions 121 are completely inserted into the processing box 114, and the crushed wood chips and dry sludge are respectively put into the second feed port 125. The output end of the second drive motor 115 is directly driven to reciprocate and drive the left end of the processing box 114 to tilt upward and downward, so that the dry sludge and wood chips are fully mixed.

Example 4

[0026] Please refer to Figure 5 As shown, the first lifting mechanism 2 includes a first guide rod 201, the bottom end of the first guide rod 201 is welded to the frame 1, the top of the first guide rod 201 is welded to the connecting plate 202, a first screw rod 203 is rotatably connected between the connecting plate 202 and the frame 1, the bottom end of the outer cylinder of the movable cover 103 is threadedly connected to the first screw rod 203, a first stepper motor 204 is fixedly installed on the top of the connecting plate 202, and the top of the first screw rod 203 is fixedly installed on the output end of the first stepper motor 204.

[0027] It can be understood by those skilled in the art that the reciprocating rotation of the output end of the first stepper motor 204 can drive the first screw rod 203 to rotate reciprocatingly, so that the movable cover 103 slides reciprocatingly up and down along the surface of the first guide rod 201, and the inner tube of the movable cover 103 slides reciprocatingly up and down along the inner wall of the ring mold 105. Example 5

[0028] Please refer to Figure 5 As shown, the second lifting mechanism 3 includes a first sleeve 301 and a telescopic member 313. The first sleeve 301 is fixedly connected to the bottom of the frame 1 through a mounting member. The first sleeve 301 is internally slidably connected to the second sleeve 302. The second sleeve 302 is internally slidably connected to the third sleeve 303. The third sleeve 303 is internally slidably connected to the fourth sleeve 304.

[0031] It can be understood by those skilled in the art that the threaded rod 305 is driven to rotate back and forth by the output end of the servo motor 307, so that the lifting block 308 reciprocates up and down. When the lifting block 308 moves upward, the telescopic member 313 is extended, and then the second sleeve 302, the third sleeve 303 and the fourth sleeve 304 all move upward, thereby driving the heating plate 106 and the rolling disc 107 to move upward; and when the lifting block 308 moves downward, the telescopic member 313 is retracted, and then the second sleeve 302, the third sleeve 303 and the fourth sleeve 304 all move downward, thereby driving the heating plate 106 and the rolling disc 107 to move downward. Example 6

[0032] Please refer to Figure 5 , Figure 6 and Figure 7 As shown, the cleaning mechanism 4 includes a second guide rod 401, which is fixedly connected to the inside of the fixed cylinder 102, and the inside of the fixed cylinder 102 is also rotatably connected to the second screw rod 402, and the second guide rod 401 is slidably connected to a lifting ring 404, and the lifting ring 404 is threadedly connected to the outer surface of the second screw rod 402, and the top of the second screw rod 402 is fixedly installed on the output end of the second stepper motor 403, and the second stepper motor 403 is fixedly installed on the inner wall of the fixed cylinder 102.

[0033] Please refer to Figure 7 As shown, the lifting ring 404 is internally rotatably connected to the second rotating gear ring 405, and the second rotating gear ring 405 is internally fixedly connected to the fixing seat 408, and an electric push rod 409 is installed on the outer side of the fixing seat 408, and the output end of the electric push rod 409 passes through the outer wall of the fixing seat 408 and is fixedly connected to one side of the connecting block 410, and a plurality of groups of cleaning rods 411 are installed on the other side of the connecting block 410, and a third drive motor 406 is installed on the top of the lifting ring 404, and a second drive gear 407 is fixedly installed on the output end of the third drive motor 406, and the second drive gear 407 is meshed with the second rotating gear ring 405.

[0034] People skilled in the art can understand that the second screw rod 402 is driven to rotate by the output end of the second stepper motor 403, so that the lifting circle 404 moves up and down along the outer surface of the second guide rod 401, thereby changing the height of the several groups of cleaning rods 411; and the second driving gear 407 is driven to rotate by the output end of the third driving motor 406, so that the second rotating gear ring 405 rotates, thereby driving the several groups of cleaning rods 411 to rotate. Example 7

[0035] Please refer to Figure 8 and Fig.10 As shown, the third lifting mechanism 5 includes a third screw rod 501, a third guide rod 502 and a third stepper motor 503, two groups of partitions 121 are respectively threadedly connected to the two groups of third screw rods 501, the two groups of third screw rods 501 are both rotatably connected to the outside of the processing box 114, two groups of third stepper motors 503 are installed on the processing box 114, the tops of the two groups of third screw rods 501 are respectively fixedly connected to the output ends of the two groups of third stepper motors 503, and the two groups of partitions 121 are also respectively slidably connected to the third guide rod 502, and the third guide rod 502 is fixedly installed on the outside of the processing box 114.

[0036] It is understandable to those skilled in the art that the reciprocating rotation of the output end of the third stepper motor 503 drives the third screw rod 501 to reciprocate, so that the partition plate 121 slides up and down reciprocatingly along the outer surface of the third guide rod 502 .

[0037] Working principle and use process of the device: In life, sludge is divided into two types, one is wet sludge containing water, and the other is dry sludge. The present invention goes through two steps when treating wet sludge or dry sludge. The first step is pretreatment, and the second step is to make biomass pellet fuel. Next, we take wet sludge as an example to explain in detail: When pre-treating wet sludge containing moisture, first, the two groups of partitions 121 are completely inserted into the interior of the treatment box 114, wet sludge is added through the first feed port 124, and then flocculant is added to the first feed port 124. The output end of the second drive motor 115 reciprocates to drive the left end of the treatment box 114 to tilt upward and downward, which has a shaking effect, so that the wet sludge and the flocculant are fully in contact. Secondly, the partition 121 close to the filter plate 116 moves upward, and then the output end of the second drive motor 115 drives the treatment box 114 to be tilted, so that the sludge treated with the flocculant all enters the top of the filter plate 116. After that, the partition 121 close to the filter plate 116 moves upward. The second bucket 122 is provided with a plurality of partitions 121, which are arranged to move downward to reset, and then the pressure plate 118 is driven downward by the output end of the cylinder 117 to squeeze the sludge, squeeze out the water in the sludge, and discharge it into the external water pool through the outlet pipe 120. Finally, the two groups of partitions 121 all move upward, and the processing box 114 is driven to be tilted by the output end of the second drive motor 115, so that the sludge after the filter press slides into the inside of the second bucket 122. Then, the two groups of partitions 121 all move downward to reset, and the crushed wood chips are introduced into the second feed port 125. Finally, the left end of the processing box 114 is driven to tilt upward and downward by the reciprocating rotation of the output end of the second drive motor 115, so that the sludge and the wood chips are fully mixed. Since there are two groups of ring die hole groups on each ring die 105, each two adjacent ring die 105 are threadedly connected, and the size of the ring die holes on each group of ring die 105 can be the same or different, and can be set according to the needs of the staff, so that biomass pellet fuels of different sizes can be well produced. The staff adjusts the height of the heating plate 106 and the grinding disc 107 through the second lifting mechanism 3, so that the height of the heating plate 106 and the grinding disc 107 is adapted to the height of a certain group of ring die hole groups to be used. After the sludge and sawdust are mixed, the valve 123 is opened to make the mixed raw materials fall on the heating plate 106, and the heating plate 106 heats the sludge and sawdust, and the grinding disc 107 rotates to extrude them, and cooperates with the ring die hole group to generate biomass pellet fuel, thereby realizing harmless treatment of sludge, being more environmentally friendly, and being able to replace traditional fuels; The generated biomass pellet fuel falls between the fixed cylinder 102 and the bottom cylinder 104, and the output end of the first driving motor 110 drives the first driving gear 111 to rotate, so that the first rotating gear ring 108 rotates, and then drives the unloading plate 109 to rotate, and the fallen biomass pellet fuel is swept out through the unloading port 112 and collected by the collecting box 126; The above description is the entire treatment process of wet sludge containing water. When treating dry sludge, first, the two sets of partitions 121 are completely inserted into the inside of the treatment box 114, and the crushed wood chips and dry sludge are respectively put into the second feed port 125. The output end of the second drive motor 115 is directly driven to reciprocate and drive the left end of the treatment box 114 to tilt upward and downward, so that the dry sludge and the wood chips are fully mixed. The steps after mixing can refer to the wet sludge; It is worth noting here that, during extrusion granulation, since only one set of ring die hole groups need to be used, before opening the valve 123, firstly, the height of the heating plate 106 and the grinding disc 107 is adapted to the height of a certain set of ring die hole groups to be used through the second lifting mechanism 3, and then the movable cover 103 is driven to move through the first lifting mechanism 2, so that the inner cylinder of the movable cover 103 covers all other ring die hole groups above the ring die hole group. The purpose of this is to prevent the falling sludge and wood chips from penetrating the ring die holes and splashing to the outside of the ring die 105 after the valve 123 is opened, thereby avoiding the waste of raw materials and the flying of the raw materials under the action of the grinding disc 107 during the granulation process, but they will not splash to the outside of the ring die 105; In addition, during the extrusion granulation process, if the ring die hole is blocked, the second screw rod 402 is driven to rotate by the output end of the second stepping motor 403, so that the height of the plurality of cleaning rods 411 matches the height of the ring die hole group, and the second driving gear 407 is driven to rotate by the output end of the third driving motor 406, so that the second rotating gear ring 405 rotates, thereby driving the plurality of cleaning rods 411 to rotate to the blocked ring die hole, and finally the output end of the electric push rod 409 is extended so that the cleaning rod 411 extends into the ring die hole to clear the blockage; It is also worth mentioning that if the ring die hole group is damaged during the extrusion granulation process, it is necessary to replace other ring die hole groups with the same aperture size, which can be achieved through the cooperation of the second lifting mechanism 3 and the first lifting mechanism 2. If all the ring die hole groups are damaged and need to be replaced, the heating plate 106 is first lowered into the bottom cylinder 104 for storage through the second lifting mechanism 3, and then all the ring mold parts 105 are disassembled. The purpose of this is to prevent the raw materials on the heating plate 106 from falling off the heating plate 106 when there is no ring mold part 105 "circling" it, thereby meeting the needs of the staff.
