Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and in particular to a sludge solid waste treatment device, and in particular to a treatment process of the sludge solid waste treatment device. Background Art

[0002] At present, most sludge dewatering and squeezing equipment squeezes and dehydrates the sludge under the action of external force, and cannot achieve centrifugal dehydration of the sludge while squeezing, which makes the sludge dehydration efficiency low and requires a long time for dehydration operation. In addition, when the sludge is squeezed and dehydrated, the sludge cannot be stirred synchronously. This causes the sludge to easily gather at the edge of the equipment during the sludge dehydration centrifugal process, making it difficult for the sewage in the sludge to flow out, which again affects the sludge dehydration efficiency.

[0003] Chinese patent CN115057600B discloses a sludge dewatering and squeezing device for sludge treatment, including a box, the bottom of the box is sealed and rotatably connected with a dewatering ring, the side wall of the dewatering ring is provided with a plurality of filter holes, a separation mechanism is provided on the box, the separation mechanism includes a sleeve ring rotatably connected to the upper end of the box, the side wall of the sleeve ring is fixedly connected to the side wall of the dewatering ring through a plurality of L-shaped plates, the upper end of the box is rotatably connected with a first rod through a bracket I, the first rod is arranged through the sleeve ring, and two stirring plates are fixedly connected below the side wall of the first rod. By setting the separation mechanism, the sludge can be stirred synchronously while the sludge is centrifugally dehydrated, so as to avoid the sludge gathering at the edge of the dewatering ring, which makes it difficult for the sewage in the sludge to flow out, thereby affecting the dewatering efficiency of the sludge, and there is a certain speed difference between the dewatering ring and the two stirring plates, so as to better complete the stirring of the sludge.

[0004] Although the above-mentioned device can dewater the sludge by centrifugal force and extrusion force, the device dewaters the sludge by cooperating with the dewatering ring and the sealing cover to pile up the stored sludge. Under the action of centrifugal force and extrusion force, the piled sludge close to the dewatering ring will be quickly dehydrated. The device stirs the squeezed sludge by a stirring plate. In the actual dewatering process, the stirring method of the stirring plate is single, and it is difficult to make the sludge in the center area evenly close to the dewatering ring.

[0015] A treatment process of a sludge solid waste treatment device comprises the following steps;

[0016] After the S1 device is started, the sludge to be treated is continuously and stably pumped into the multi-stage injection device through a precisely controlled delivery pump. The multi-stage injection device is equipped with a diversion structure to ensure that the sludge can be evenly and equally distributed to each filter chamber of the multi-stage filter below, effectively avoiding excessive accumulation of sludge in local areas and laying the foundation for the uniformity of the subsequent dehydration process.

[0017] S2 When the sludge injection volume reaches the preset value, the system automatically stops sludge input and prepares to enter the centrifugal dehydration stage.

[0018] The S3 rotary drive device starts, driving the multi-stage filter and the matching guide shell to rotate synchronously at high speed. During the rotation process, the sludge is subjected to strong centrifugal force, and the internal water is effectively thrown out and collected by the centrifugal dehydration bucket and then discharged, realizing rapid centrifugal dehydration. At the same time, the rotating guide shell guides the surrounding air flow, forming a continuous air drying effect on the sludge surface, further improving the dehydration efficiency and effect.

[0019] While S4 is rotating and dehydrating, the pressure device applies downward pressure to the multi-stage injection tool, and the pressure is evenly transmitted to the sludge layer. Under the dual effects of centrifugal force and mechanical extrusion, the internal moisture of the sludge is discharged more efficiently, accelerating the dehydration process and ensuring the uniformity of the dehydration effect.

[0020] S5 After the set dehydration treatment time, the moisture content in the sludge reaches the preset standard. At this time, the automatic sealing base responds to the control signal and opens. The dehydrated sludge loses support at the bottom of the multi-stage filter. The sludge falls off the filter and enters the collection device below or directly enters the next step of processing or storage.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This device adopts a multi-stage dehydration device design. By accurately controlling the sludge distribution to each filter chamber, it avoids excessive accumulation of sludge in a single area and ensures uniformity during the dehydration process. At the same time, the dual effects of centrifugal dehydration and mechanical extrusion not only accelerate the discharge of water inside the sludge, but also ensure the comprehensiveness of the dehydration effect, so that the water content in the sludge quickly reaches the preset standard, significantly improving the overall dehydration efficiency.

[0023] 2. The built-in multi-stage filter not only uses centrifugal force to effectively remove the water in the sludge during the rotation process, but also guides the surrounding air flow through the design of the guide shell to form a continuous air drying effect on the sludge surface. Compared with the traditional single dehydration method, this innovative dehydration method combining centrifugal and air drying can more thoroughly remove the water in the sludge, further improve the dehydration effect, and reduce the dependence on external heat sources or energy, reducing energy consumption and costs.

[0024] 3. This device integrates an automated control system to achieve full automation from sludge injection, centrifugal dehydration, mechanical extrusion to discharging. Through intelligent sensing and control technology, the operating parameters and timing of each link are accurately controlled to ensure the stability and reliability of the dehydration process. In addition, the design of the automatic plugging base automatically opens after the dehydration is completed, allowing the dehydrated sludge to be discharged smoothly without manual intervention, reducing labor intensity and improving work efficiency and safety. Overall, the automation and intelligent management characteristics of the device not only improve the efficiency and quality of sludge treatment, but also save a lot of labor costs and maintenance costs for the enterprise.

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 10 As shown, a sludge solid waste treatment device includes a high-efficiency dehydration device for quickly dehydrating sludge, the high-efficiency dehydration device includes a centrifugal dehydration barrel 1, a multi-stage dehydration device 2, a multi-stage injection device 3, a pressure device 4 and an automatic blocking base 5; the centrifugal dehydration barrel 1 is used to collect the separated wastewater; the multi-stage dehydration device 2 is arranged inside the centrifugal dehydration barrel 1, and the multi-stage dehydration device 2 includes a multi-stage filter 22 installed inside the centrifugal dehydration barrel 1, and the multi-stage filter 22 is provided with a plurality of filter chambers inside. 2 is provided with a flow guide shell 23 on the outer side, and the multi-stage dehydration device 2 also includes a rotating drive device 21 for driving the multi-stage filter 22 to rotate; the multi-stage injection tool 3 is installed above the multi-stage filter 22, and the output end of the multi-stage injection tool 3 extends to the inside of the filter chamber; the pressure device 4 is arranged above the multi-stage injection tool 3, and the pushing end of the pressure device 4 is connected to the multi-stage injection tool 3; the automatic blocking base 5 is arranged at the bottom of the multi-stage dehydration device 2, and the automatic blocking base 5 is used to block the bottom of the multi-stage dehydration device 2.

[0039] When the device is started, the sludge to be treated is continuously and stably pumped into the multi-stage injection device 3 through the delivery pump. The multi-stage injection device 3 is designed with a precise diversion structure to ensure that the sludge can be evenly and equally distributed to each filter chamber of the multi-stage filter 22 below. This process effectively avoids excessive accumulation of sludge in a certain area to ensure the uniformity of the subsequent dehydration process. When the sludge injection reaches a preset amount, the rotary drive device 21 starts to drive the multi-stage filter 22 and the guide shell 23 to rotate synchronously at high speed. During the rotation process, the sludge is subjected to the action of centrifugal force, and the water inside it is effectively thrown out and collected and discharged through the centrifugal dehydration barrel 1. This step realizes the rapid centrifugal dehydration of the sludge. At the same time, the rotating guide shell 23 will guide the surrounding air flow, forming a continuous air drying effect on the sludge surface. This dual dehydration mechanism combining centrifugation and air drying significantly improves the dehydration efficiency and effect. While rotating the centrifugal dehydration, the pressure device 4 applies downward pressure to the multi-stage injection device 3. This pressure is evenly transmitted to the sludge layer through the multi-stage injection device 3, so that the sludge is further mechanically squeezed on the basis of centrifugal force. This dual effect greatly accelerates the discharge of water in the sludge, improves the dehydration efficiency, and ensures the uniformity of the dehydration effect. After a period of dehydration treatment, the moisture content in the sludge reaches the preset standard, and the automatic blocking base 5 responds to the control signal to open. If the dehydrated sludge loses support at the bottom of the multi-stage filter 22, it will fall off the multi-stage filter 22 and enter the next step of processing or storage. The entire dehydration process is automatically controlled, from sludge injection, centrifugal dehydration, mechanical extrusion to discharging, each link is closely connected, which greatly improves the processing efficiency. The device effectively solves the problems existing in traditional sludge dehydration devices through its unique multi-layer centrifugal dehydration mechanism, the dehydration method combining diversion air drying and mechanical extrusion, and the automated operation process, and realizes efficient and uniform sludge dehydration treatment. The rotary drive device 21 is a prior art and will not be repeated here. The multi-stage filter 22 and the flow guide housing 23 are fixedly connected by a plurality of connecting screws 24, so as to facilitate later disassembly and maintenance.

[0040] See also Figure 2 , Figure 4 and Figure 5 As shown, the multi-stage filter 22 includes a first mounting base 221, on which a plurality of arc-shaped material storage bars 222 are provided, the inner wall of the arc-shaped material storage bars 222 is covered with filter holes 223, a feed port 225 is installed at the upper end of the arc-shaped material storage bars 222, a drop port 224 is provided at the bottom of the arc-shaped material storage bars 222, and a water-absorbing filter layer 226 is provided on the outer side of the arc-shaped material storage bars 222, and a vibration motor 227 is also installed on the first mounting base 221.

[0041] The first mounting base 221 is rotatably connected to the centrifugal dehydration barrel 1 , and the first mounting base 221 is transmission-connected to the rotary drive device 21 .

[0042] The multi-stage injection device 3 is designed with a precise diversion structure to ensure that the sludge can be evenly and equally distributed to each arc-shaped storage bar 222 of the multi-stage filter 22 below. This process effectively avoids excessive accumulation of sludge in a certain area and ensures the uniformity of the subsequent dehydration process. The setting of the multi-stage filter 22 allows the sludge to be carried out layer by layer during the dehydration process, and each layer can be fully centrifuged and squeezed, thereby ensuring the uniformity of the dehydration effect. The rotating guide shell 23 not only enhances the centrifugal effect, but also cleverly guides the flow of surrounding air to form a continuous air-drying effect on the sludge surface. This dual dehydration mechanism combining centrifugation and air drying further improves the dehydration effect. The water-absorbing filter layer 226 sleeved on the outside of the arc-shaped storage bar 222 has good water absorption performance, which can continuously absorb and retain the water separated from the sludge during the rotation process, reduce water reflux, and improve the dehydration quality. The vibration motor 227 installed on the first mounting base 221 is started in time during the dehydration process. The vibration effect can cause the tiny particles inside the sludge layer to be redistributed, reduce the agglomeration phenomenon, and help to discharge the residual water faster. The synergistic effect of vibration, centrifugation and extrusion further enhances the dehydration effect. At the same time, the vibration force of the vibration motor 227 can assist in the sludge removal.

[0043] See also Figure 4 , Figure 5 and Figure 6 As shown, the guide housing 23 includes a second mounting base 231 , on which a plurality of arc-shaped limiting shells 232 are disposed. The arc-shaped limiting shells 232 are provided with interlaced tracks 234 inside, and the outer wall of the arc-shaped limiting shells 232 is covered with air inlet holes 235 .

[0044] A plurality of arc-shaped limiting shells 232 are provided on the second mounting base 231 of the flow guide housing 23. These arc-shaped limiting shells 232 are sleeved on the outer sides of the arc-shaped material storage bar 222 and the water absorption filter layer 226 through the interlaced rails 234. The outer wall of the arc-shaped limiting shell 232 is covered with air inlet holes 235, which facilitate the airflow to contact the water absorption filter layer 226. The rotating flow guide housing 23 can effectively ensure the stability of the installation of the water absorption filter layer 226, and also cleverly guide the surrounding air flow to form a continuous air drying effect on the sludge surface. This dual dehydration mechanism combining centrifugation and air drying further improves the dehydration effect.

[0045] See also Figure 6 As shown, a plurality of guide vanes 236 are installed on the outer side of the arc-shaped limiting shell 232 , and the guide vanes 236 are distributed in a stepped manner.

[0046] During the rotation process, the guide vanes 236 not only enhance the overall stability of the guide housing 23, but also further promote the flow and distribution of the airflow. The stepped distribution enables the airflow to form a more complex and effective flow pattern when it flows through the guide vanes 236 at different levels, thereby improving the air drying effect on the sludge surface.

[0047] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the multi-stage injection tool 3 includes a third mounting base 31, on which a plurality of push plates 32 are mounted, the push plates 32 matching the number of the arc-shaped material storage bars 222, the push plates 32 being used to extend into the interior of the arc-shaped material storage bars 222, the push plates 32 being provided with injection holes 321, the injection holes 321 being connected to the injection pipe 33, the injection pipe 33 being provided with a solenoid valve 34, and the bottom of the push plate 32 being provided with a first pressure sensor 35 and a moisture detector 36.

[0048] When the device is started, the sludge to be treated is continuously and stably pumped into the multi-stage injection device 3 through the delivery pump. The multi-stage injection device 3 includes a third mounting base 31, on which a plurality of push plates 32 matching the number of arc-shaped storage bars 222 are mounted. Each push plate 32 is provided with an injection hole 321, which is connected to the injection pipe 33, and a solenoid valve 34 is installed on the injection pipe 33 to control the injection speed and amount of the sludge. The design of the push plate 32 enables the sludge to be directly and accurately injected into each arc-shaped storage bar 222 of the multi-stage filter 22 below. At the same time, the first pressure sensor 35 installed on the push plate 32 monitors the injection pressure of the sludge in real time to ensure that the sludge can be evenly and equally distributed to each arc-shaped storage bar 222, and the moisture detector 36 installed on the push plate 32 is used to monitor the moisture in the sludge in real time. When the sludge injection reaches a preset amount, the rotary drive device 21 starts, driving the multi-stage filter 22 and the guide shell 23 to rotate synchronously at high speed. During the rotation process, the sludge is subjected to the action of centrifugal force, and the water inside it is effectively thrown out and collected and discharged through the centrifugal dehydration barrel 1. At the same time, the rotating guide shell 23 not only enhances the centrifugal effect, but also cleverly guides the flow of surrounding air to form a continuous air-drying effect on the sludge surface. This dual dehydration mechanism combining centrifugation and air drying significantly improves the dehydration efficiency and effect. While rotating the centrifugal dehydration, the pressure device 4 applies downward pressure to the multi-stage injection device 3. This pressure is evenly transmitted to the sludge layer through the push plate 32, so that the sludge is further mechanically squeezed on the basis of centrifugal force. This dual action greatly accelerates the discharge of water from the sludge, improves the dehydration efficiency, and ensures the uniformity of the dehydration effect.

[0049] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the pressure-applying device 4 includes a mounting rail 41 mounted on the third mounting base 31, a connecting bracket 42 is mounted on the mounting rail 41, the connecting bracket 42 is slidably connected to the mounting rail 41, a pressure push plate 43 is mounted on the connecting bracket 42, a buffer spring 44 is installed between the pressure push plate 43 and the connecting bracket 42, and the pressure-applying device 4 also includes a first ball screw slide 45 mounted on the centrifugal dehydration barrel 1, and the first ball screw slide 45 is connected to the pressure push plate 43.

[0050] After the sludge is evenly distributed to each arc-shaped storage bar 222 through the multi-stage injection device 3 and the rotating centrifugal dehydration process is started, the pressure device 4 immediately enters the working state. The pressure device 4 is mainly composed of a mounting rail 41 installed on the third mounting base 31, a connecting bracket 42 slidably connected to the mounting rail 41, a pressure push plate 43 installed on the connecting bracket 42, a buffer spring 44, and a first ball screw slide 45 connected to the centrifugal dehydration barrel 1. With the start of the centrifugal dehydration process, the first ball screw slide 45 receives a control signal and drives the pressure push plate 43 to slide downward along the mounting rail 41. In this process, the buffer spring 44 plays a key buffering and shock absorbing role, ensuring that the pressure push plate 43 can steadily and evenly apply pressure to the sludge layer, avoiding damage to the device or affecting the dehydration effect due to excessive instantaneous impact force. As the pressure push plate 43 moves downward, the downward mechanical pressure is evenly transmitted to the sludge layer in each arc-shaped storage bar 222 through the push plate 32. At this time, the sludge layer is subjected to centrifugal force and mechanical pressure from above. This dual effect greatly enhances the ability to discharge water from the sludge. The centrifugal force causes the water in the sludge to be thrown out and collected and discharged through the centrifugal dewatering barrel 1, while the mechanical pressure further compresses the sludge and accelerates the release of remaining water.

[0051] See also Figure 2 , Figure 3 and Figure 7 As shown, the automatic blocking base 5 includes an upper limit mounting rail 51 installed on the multi-section injection mold 3, a rotating blocking plate 54 is installed inside the limiting mounting rail 51, a plurality of sealing surfaces 541 and blanking holes 542 are provided on the rotating blocking plate 54, a return spring 52 is installed between the rotating blocking plate 54 and the limiting mounting rail 51, a second pressure sensor is also provided inside the limiting mounting rail 51, a rotating handle 53 is installed on the outer side of the rotating blocking plate 54, and the automatic blocking base 5 also includes a limiting blocking device 55 for automatically blocking the rotating handle 53 from rotating.

[0052] The automatic blocking base 5 blocks and unblocks the discharge port 224 at the bottom of the multi-stage filter 22 by rotating the blocking plate 54. When the sludge dehydration reaches the preset standard, the multi-stage dehydration device 2 drives the multi-stage filter 22 to rotate at a low speed. At this time, the limit blocking device 55 blocks the rotating handle 53, so that the rotating blocking plate 54 stops rotating. The multi-stage filter 22 continues to drive the limit mounting rail 51 to rotate until the discharge hole 542 on the rotating blocking plate 54 docks with the discharge port 224 of the arc-shaped storage bar 222, so that the sludge loses its supporting force. At the same time, the sludge is quickly discharged from the discharge port 224 under the influence of the vibration motor 227 of the multi-stage filter 22.

[0053] The return spring 52 in the limit mounting rail 51 is used to push the rotating sealing plate 54 to maintain the specified position to ensure the sealing effect. The second pressure sensor detects the pressure of the return spring 52 to determine the position state of the rotating sealing plate 54 to ensure accurate control of the dehydration and stripping process.

[0054] See also Figure 2 , Figure 3 and Figure 8 As shown, the position limiting blocking device 55 includes a guide rail 551 installed at the bottom of the centrifugal dehydration barrel 1, a blocking block 553 is installed inside the guide rail 551, and a linear driver 552 for driving the blocking block 553 to move is also installed on the guide rail 551.

[0055] During the sludge dehydration process, the sealing surface 541 on the rotating sealing plate 54 is in close contact with the blanking opening 224 of the arc-shaped storage bar 222, forming an effective blockage to prevent the sludge from falling off prematurely. At this time, the second pressure sensor monitors the pressure value of the reset spring 52 to ensure the reliability of the blockage. When the sludge dehydration reaches the preset standard, the system sends a signal to prepare for the dehydration operation. The multi-stage dehydration device 2 drives the multi-stage filter 22 and the limit mounting rail 51 to rotate at a low speed. At the same time, the linear drive 552 starts, pushing the blocking block 553 to move to the specified position along the guide rail 551, blocking the further rotation of the rotating handle 53. At this time, the rotating sealing plate 54 stops rotating due to being blocked, but the limit mounting rail 51 and the multi-stage filter 22 continue to rotate. As the limit mounting rail 51 continues to rotate, the blanking hole 542 on the rotating sealing plate 54 gradually docks with the blanking opening 224 of the arc-shaped storage bar 222. The reset spring 52 is further compressed, and the second pressure sensor detects the pressure change. After the material stripping is completed, the linear drive 552 withdraws the blocking block 553, and the reset spring 52 pushes the rotating sealing plate 54 back to the initial position to prepare for the next sealing operation.

[0056] See also Figure 1 and Figure 2As shown, a second ball screw slide 14 is provided inside the centrifugal dehydration barrel 1, a disengagement port 11 and a drainage port 12 are provided at the bottom of the centrifugal dehydration barrel 1, and a lifting mounting plate 13 is also installed inside the centrifugal dehydration barrel 1, which is transmission-connected to the second ball screw slide 14.

[0057] The second ball screw slide 14 is installed inside the centrifugal dehydration barrel 1. As a key component for power transmission and position control, its high precision and stability ensure the accurate movement of the lifting mounting plate 13. The lifting mounting plate 13 is firmly mounted on the second ball screw slide 14 and closely cooperates with it through a transmission connection. A multi-stage dehydration device 2 is installed on the lifting mounting plate 13. The disengagement port 11 is located at the bottom of the centrifugal dehydration barrel 1. When the lifting mounting plate 13 descends, the multi-stage filter 22 and the guide shell 23 will exit the centrifugal dehydration barrel 1 through this port, which is convenient for daily maintenance. The drain port 12 is also located at the bottom of the centrifugal dehydration barrel 1, which is used to guide the discharge of wastewater generated during the dehydration process to maintain the cleanliness and dehydration efficiency of the inside of the centrifugal dehydration barrel 1.

[0058] When routine maintenance is required, the control system starts the second ball screw slide 14. The second ball screw slide 14 drives the lifting mounting plate 13 to descend smoothly in the specified direction. As the lifting mounting plate 13 descends, the multi-segment filter 22 and the flow guide shell 23 installed thereon gradually detach from the working environment inside the centrifugal dehydration barrel 1 until they are completely exited through the disengagement port 11. The staff can easily access the multi-segment filter 22 and the flow guide shell 23 to perform maintenance work such as cleaning, inspection or replacement without having to enter the centrifugal dehydration barrel 1 or perform complicated disassembly operations. Effectively improve maintenance efficiency.

[0059] A treatment process of a sludge solid waste treatment device comprises the following steps;

[0060] After S1 starts the device, the sludge to be treated is continuously and stably pumped into the multi-stage injection device 3 through a precisely controlled delivery pump. The multi-stage injection device 3 is provided with a diversion structure to ensure that the sludge can be evenly and equally distributed to each filter chamber of the multi-stage filter 22 below, effectively avoiding excessive accumulation of sludge in local areas, and laying the foundation for the uniformity of the subsequent dehydration process.

[0061] S2 When the sludge injection volume reaches the preset value, the system automatically stops sludge input and prepares to enter the centrifugal dehydration stage.

[0062] S3 The rotary drive device 21 is started, driving the multi-stage filter 22 and the matching guide shell 23 to rotate synchronously at high speed. During the rotation process, the sludge is subjected to strong centrifugal force, and the internal water is effectively thrown out and collected by the centrifugal dehydration barrel 1 and then discharged, realizing rapid centrifugal dehydration. At the same time, the rotating guide shell 23 guides the surrounding air flow, forming a continuous air drying effect on the sludge surface, further improving the dehydration efficiency and effect.

[0063] While S4 is rotating for centrifugal dehydration, the pressure device 4 applies downward pressure to the multi-stage injection device 3, and the pressure is evenly transmitted to the sludge layer. Under the dual effects of centrifugal force and mechanical extrusion, the internal moisture of the sludge is discharged more efficiently, accelerating the dehydration process and ensuring the uniformity of the dehydration effect.

[0064] S5 After the set dehydration treatment time, the moisture content in the sludge reaches the preset standard. At this time, the automatic blocking base 5 responds to the control signal to open, and the dehydrated sludge loses support at the bottom of the multi-stage filter 22. The sludge falls off the filter and enters the collection device below or directly enters the next step of processing or storage.

[0065] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
