Sludge contains a large number of harmful substances, such as heavy metals, pathogens, organic matter, etc. If not properly treated, it will not only occupy a large amount of land resources, but also cause serious pollution to the environment, threatening the ecological balance and human health. Therefore, sludge treatment is an indispensable important link in the sewage treatment process and is of great significance for realizing the recycling of water resources and environmental protection.

[0003] The existing sludge dehydration and separation work mainly realizes the treatment and recycling of sludge and waste by putting sludge into a stacked screw machine, separating the sludge from the sewage, and discharging the two outwards respectively, thereby reducing water resource consumption and reducing environmental pollution.

[0004] However, the existing multi-layer stacked screw sludge deep dehydration and separation equipment has the following deficiencies:

[0005] 1) The existing multi-layer stacked screw sludge deep dehydration and separation equipment cannot adjust the distance between the fixed ring and the floating ring, resulting in poor actual sludge dehydration and separation effect, easy to cause blockage, thus affecting the efficiency of sludge treatment work and difficult to meet the actual use requirements.

[0006] 2) The existing multi-layer stacked screw sludge deep dehydration and separation equipment cannot treat the odor gas generated during sludge treatment, resulting in the escape of odor gas and causing large-scale air pollution, affecting the physical and mental health of workers.

[0007] 3) The existing multi-layer stacked screw sludge deep dehydration and separation equipment cannot dry the separated sludge in time, resulting in low efficiency of squeezing the sludge cake and easy to cause secondary pollution to the external environment, increasing the difficulty of subsequent operation and maintenance and cleaning.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to the attached Figure 1 - attached Figure 9 As shown in the figure, the present invention provides a technical solution: a multi-layer stacked screw sludge deep dehydration and separation device, including an equipment body 1,

[0044] A sludge inlet end 2, installed at one end of the equipment body 1;

[0048] The spacing adjustment and cleaning mechanism 4 includes a fixed frame 401. The fixed frame 401 is fixedly installed at one end of the sludge inlet end 2. A first servo motor 402 is installed on one side of the fixed frame 401. The output end of the first servo motor 402 is connected to the spiral dewatering assembly. A first belt drive structure 403 is installed outside the output end of the first servo motor 402. One end of the first belt drive structure 403 is provided with two first connecting shafts 404. One end of each of the two first connecting shafts 404 movably penetrates through the equipment body 1 and is connected to a cleaning brush roller 405. A second belt drive structure 406 is installed outside the output end of the first servo motor 402.

In addition, both the first belt drive structure 403 and the second belt drive structure 406 are composed of three belt pulleys and a drive belt sleeved outside these belt pulleys. The main purpose of this structural design is to use the drive belt to transmit the rotational force generated by the main belt pulley, so as to achieve the effect of reducing the use of the power source and further reducing the usage cost of the equipment.

[0049] According to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, an air purification mechanism 11 is provided at the top of the equipment body 1;

Through the setting of the air purification mechanism 11, it can ensure that during the process of sludge dewatering and separation, the odor gases generated therefrom are effectively concentrated and inhaled, and processed through the filtration and purification system, thereby effectively preventing the escape of these odor gases and avoiding large-scale air pollution problems. This measure not only helps to protect the environment but also ensures the physical and mental health of the staff, providing them with a safer and more comfortable working environment.

[0051] According to Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a heating and drying mechanism 12 is provided at the top of the mud cake discharge end 3;

[0052] The heating and drying mechanism 12 includes a fixed cavity 1201, which is fixedly installed at the top of the mud cake discharge end 3. A metal frame 1202 is inserted into the inner side of the fixed cavity 1201, and a plurality of electric heating wires 1203 are arranged inside the metal frame 1202. A second axial flow fan 1204 is installed at the top of the fixed cavity 1201. Through the setting of the heating and drying mechanism 12, it can effectively realize the rapid drying process of the separated sludge. This process not only significantly reduces the difficulty of squeezing the mud cake but also helps the rapid forming of the mud cake. In this way, it can effectively prevent secondary pollution during the sludge treatment process, thereby further simplifying the difficulty of subsequent cleaning work.

[0053] According to Figure 4 As shown, the stacked screw dewatering assembly includes a plurality of fixed rings 5, which are all installed inside the equipment body 1. A floating ring 6 is arranged between every two fixed rings 5. A spiral shaft 7 is arranged inside the plurality of fixed rings 5 and floating rings 6. Through the setting of the stacked screw dewatering assembly, it can realize the efficient separation of sludge and sewage, thereby significantly reducing the difficulty of subsequent sludge treatment. This efficient separation technology not only improves the overall work efficiency but also greatly saves labor costs and time costs, making the whole treatment process more economical and efficient.

[0054] According to Figure 4As shown, one end of the spiral shaft 7 is connected to the output end of the first servo motor 402, and the other end of the spiral shaft 7 is connected with a back pressure plate 8. The back pressure plate 8 is arranged inside the mud cake discharge end 3. Through the arrangement of the back pressure plate 8, it can effectively squeeze and compress the separated sludge into the form of a mud cake quickly. This process not only improves the efficiency of sludge treatment, but also greatly facilitates the subsequent collection of these mud cakes. The collected mud cakes can be concentrated and then processed more systematically and standardized. Whether it is used for land improvement, production of building materials, or other environmentally friendly resource recycling, it becomes easier and more feasible.

[0055] According to Figure 1 、 Figure 2 and Figure 6 As shown, a sludge conveying mechanism 9 is arranged outside the sludge inlet end 2, and an accelerating flocculation mechanism 10 is arranged at one end of the sludge conveying mechanism 9;

[0056] The sludge conveying mechanism 9 includes a conveying pipeline 901. One end of the conveying pipeline 901 is connected to the sludge inlet end 2, the other end of the conveying pipeline 901 is connected with a screw pump 902, the output end of the screw pump 902 is connected with a connecting pipeline 903, one end of the connecting pipeline 903 is connected to the accelerating flocculation mechanism 10, and a fixing plate 904 is arranged at the bottom of the screw pump 902. The fixing plate 904 is fixedly installed on one side of the accelerating flocculation mechanism 10. Through the arrangement of the sludge conveying mechanism 9, it can effectively convey the flocculated sludge smoothly. Such a design not only ensures the smooth operation of the whole equipment, reduces the possibility of blockage, but also significantly improves the operation efficiency of the whole system. In addition, this optimized conveying mechanism helps to reduce the difficulty and cost faced by the equipment during the later operation and maintenance, thus bringing a more economical and efficient sludge treatment solution for users.

[0057] According to Figure 1 、 Figure 2 and Figure 6 As shown, the accelerating flocculation mechanism 10 includes a flocculation bin 1001. An anti-slip bracket 1002 is arranged at the bottom of the flocculation bin 1001, a sludge addition port 1003 is arranged at the top of the flocculation bin 1001, a flocculant addition port 1004 is arranged at the top of the flocculation bin 1001, a second servo motor 1005 is installed at the top of the flocculation bin 1001, the output end of the second servo motor 1005 movably penetrates through the flocculation bin 1001 and is connected with a stirring shaft 1006, and a plurality of stirring blades 1007 are evenly distributed on the outer side of the stirring shaft 1006. Through the careful design and configuration of the accelerating flocculation mechanism 10, it can effectively accelerate the sludge flocculation process, significantly shorten the time required for flocculation, and thus further improve the overall working efficiency.

[0058] According to Figure 1 、Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown in Figure 2 , Figure 3 , Figure 4 and Figure 9 , the intelligent locking mechanism 15 includes a mounting bracket 1501. The mounting bracket 1501 is arranged on the outer side of one end of the second belt transmission structure 406. Two fastening bolts 1502 are installed on the top of the mounting bracket 1501, and an intelligent electronic lock shaft device 1503 is installed on the top of the mounting bracket 1501. Through the setting of the intelligent locking mechanism 15, the user can precisely control the linkage relationship between the various components inside the spacing adjustment and cleaning mechanism 4. This delicate adjustment ensures the stability of the equipment during the overall operation process, thereby effectively extending the service life of the equipment. In addition, the high controllability of the intelligent locking mechanism 15 provides great convenience for the operator, making the maintenance and adjustment of the equipment more flexible and efficient.

[0059] According to Figure 1 , Figure 2 , Figure 3 , and Figure 4 As shown in ,

[0059] , Figure 1 , Figure 2 , Figure 3 and Figure 4 , a diversion block 13 is installed on the inner bottom side of the equipment body 1, and a drain pipe 14 is installed at the bottom of one side of the equipment body 1. Through the setting of the diversion block 13 and the drain pipe 14, the diversion of the sewage after separation treatment can be effectively realized. This process not only ensures that the sewage can smoothly pass through the drain pipe 14 and be quickly discharged, but also significantly improves the efficiency of the entire treatment process. In addition, this efficient drainage system can also greatly save labor and time costs, thereby bringing higher economic benefits to the relevant operations.

[0060] According to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in ,

[0060] , Figure 1 , Figure 2 , Figure 3 and Figure 4 , support frames 16 are installed at the four corners of the bottom of the equipment body 1, and an anti-slip pad 17 is fixedly installed at the bottom of each support frame 16. Through the setting of the support frames 16 and the anti-slip pads 17, stable support can be provided for the equipment body 1, and at the same time, the anti-slip pads 17 are used to increase the friction force to prevent the equipment from shaking significantly and improve its stability.

[0061] Working principle: First, move and transport the equipment body 1 to the designated position so that the support frames 16 and the anti-slip pads 17 are in contact with the ground to provide stable support for the equipment body 1. Then, connect the external power supply to the electrical equipment in the equipment body 1 to ensure its normal operation. Next, form a closed information interaction and collaborative operation between the external control system and the intelligent electronic lock shaft device 1503 to achieve an efficient control scheme.

[0062] In the flocculation treatment stage, first, the sludge is added into the flocculation bin 1001 from the sludge addition port 1003, and then a flocculant is put into the flocculation bin 1001 from the flocculant addition port 1004. Next, the second servo motor 1005 is started, and the second servo motor 1005 drives the stirring shaft 1006 to drive the stirring blades 1007 to rotate, stirring the sludge and the flocculant to make them quickly mix and react.

[0063] In the conveying treatment stage, the screw pump 902 is started. The screw pump 902 pumps the sludge after flocculation treatment out of the flocculation bin 1001 through the connecting pipe 903 and transports it to the sludge inlet end 2 through the conveying pipe 901. At this time, the first servo motor 402 is started, and the first servo motor 402 drives the spiral shaft 7 to rotate to convey the sludge. During the conveying process, the spiral shaft 7 squeezes the floating ring 6, making it slide between the fixed rings 5, prompting the water in the sludge to be separated. The separated sewage falls, and under the guidance of the diversion block 13, it is discharged to the outside through the drain pipe 14. During this process, the first belt drive structure 403 can transmit the rotational force generated by the operation of the first servo motor 402 to the first connecting shaft 404, and the first connecting shaft 404 drives the cleaning brush roller 405 to rotate to clean the fixed rings 5 and the floating ring 6 to prevent blockage. At the same time, according to the actual treatment requirements, the external control system controls the intelligent electronic lock shaft device 1503 to start, making the second connecting shaft 407 interlock and operate with the second belt drive structure 406. Furthermore, the second connecting shaft 407 drives the threaded rod 408 to rotate to adjust the distance between the fixed rings 5 and the floating ring 6 so that it can meet diverse treatment requirements.

[0064] In the odor treatment stage, during the process of sludge dehydration and separation, the first axial flow fan 1105 is started. The first axial flow fan 1105 sucks the odor gas generated by sludge treatment into the filtration bin 1101 through the intake pipe 1102, and the activated carbon filter plate 1104 is used to adsorb and filter the odor molecules in the gas, thereby purifying the gas and preventing large-scale air pollution.

[0065] In the sludge cake discharge stage, after the sludge undergoes dehydration and separation treatment, the spiral shaft 7 transports it to the sludge cake discharge end 3. At this time, the heating wire 1203 is started, and after the heating wire 1203 is powered on, the temperature gradually rises. Then, the second axial flow fan 1204 is started to blow the heat towards the sludge, making the sludge dry under the heat. At the same time, the back pressure plate 8 exerts pressure on the dried sludge, prompting the sludge to be extruded into a sludge cake, and the sludge cake falls and is discharged from the bottom of the sludge cake discharge end 3.

[0066] Operating according to the above content can complete the use of the multi-layer stacked screw sludge deep dehydration and separation equipment.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
