Description

Technical Field

[0001] This utility model relates to the field of sludge storage and transportation technology, specifically to a sludge storage and transportation device. Background Technology

[0002] Sludge storage and transportation is the process of collecting, storing, and transporting sludge generated during wastewater treatment to treatment or disposal sites. Sludge typically contains moisture and pollutants, requiring appropriate storage and transportation methods to prevent environmental pollution. During storage and transportation, it is essential to ensure sludge does not leak, odor is controlled, and pathogens are protected. This typically involves using sealed equipment and specialized vehicles to ensure a safe and efficient process, ultimately achieving the goal of harmless treatment or resource utilization of the sludge.

[0003] Traditional storage and transportation methods include silo buffering followed by truck transfer and direct transfer via sludge ground loaders. Due to the characteristics of sludge, silos are prone to sticking to the walls, making it difficult for level sensors to accurately measure the amount of sludge loaded. Over time, this leads to a reduction in the effective capacity of the silos. Furthermore, because the operation is outdoors, a large amount of sludge is carried to the area outside the sludge storage room during the sludge loading process. The entire sludge loading site generates a lot of dust on sunny days and a lot of mud on rainy days. Moreover, sludge loading requires specially equipped loaders and operators. The entire process requires manual intervention to instruct the next action and coordinate the various equipment to complete the relevant tasks in sequence. This results in low efficiency in material measurement, equipment operation, and management of the transfer process, and high operating costs. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figures 1-6 As shown, in one embodiment, a sludge storage and transportation device includes: a feeding assembly, a leveling assembly 2, and a sealing assembly 3. The leveling assembly 2 is symmetrically arranged below the feeding assembly 1, while the sealing assembly 3 is arranged below the leveling assembly 2.

[0033] Please continue reading. Figures 1-6 In this embodiment, the feeding assembly 1 includes a feeding hopper 11, a bellows 12, and a shaftless screw conveyor 13, with the shaftless screw conveyor 13 connecting the feeding hopper 11 and the bellows 12.

[0034] Furthermore, the feed hopper 11 is located at the top of one side of the shaftless screw conveyor 13 to receive sludge transported from the upstream equipment. A connecting flange 14 is provided at the top of the feed hopper 11 to connect to the upstream equipment and receive the sludge transported from it. The sludge is then evenly introduced into the shaftless screw conveyor 13 through its internal space. The bellows 12 is located at the bottom of one side of the shaftless screw conveyor 13. The retractable bellows 12 is connected to the sealing assembly 3 to ensure sealing and continuous feeding, preventing sludge leakage during transport. During feeding, the shaftless screw conveyor 13 can rotate in both directions using a drive motor installed on one side. The sludge entering from the top feed hopper 11 is then alternately transported to the bellows 12, and subsequently falls into the lower sludge tank 4 through the sealing assembly 3, ensuring continuous sludge transport. Furthermore, the speed and direction of the motor can be adjusted as needed to achieve quantitative sludge transport.

[0035] Please continue reading. Figures 1-6 In this embodiment, the material leveling component 2 includes a servo motor leveling system 21, a lifting module 22, and a material-distributing paddle 23. The servo motor leveling system 21 is mounted on the lifting module 22, and the servo motor leveling system 21 and the material-distributing paddle 23 are connected. Under the action of the lifting module 22, the servo motor leveling system 21 and the material-distributing paddle 23 can descend into the sludge tank 4 to ensure that the leveling operation can cover the bottom and edge of the entire sludge tank 4. Subsequently, the servo motor leveling system 21 drives the material-distributing paddle 23 to achieve peak reduction and leveling of the sludge inside the sludge tank 4, promoting the uniform distribution of sludge throughout the entire sludge tank 4.

[0036] Furthermore, the servo motor feeding system 21 is equipped with a torque meter, which can provide feedback control to the feeding blade 23, sense the resistance changes of the feeding blade 23 during operation, and adjust the working parameters of the servo motor in a timely manner to ensure that the feeding blade 23 is always in the best working state.

[0037] Please continue reading. Figures 1-6 In this embodiment, the sealing assembly 3 includes a sealing frame 31, a positioning cylinder 32, and a switching cylinder 33. The positioning cylinder 32 and the switching cylinder 33 are disposed on the sealing frame 31 and are used to seal and switch the sludge tank 4.

[0038] Furthermore, positioning cylinders 32 are symmetrically arranged on both sides of the sealing frame 31 for positioning sludge tank 4; switching cylinders 33 are symmetrically arranged in the middle of the sealing frame 31 for switching sludge tank 4.

[0039] Specifically, the steel sealing frame 31 contacts the top of the sludge tank 4, and a sealing strip 34 is provided on the contact surface to ensure the tightness of the seal and prevent sludge from leaking out during the treatment process. In order to ensure the durability and reliability of the sealing effect, the sealing strip 34 is made of polytetrafluoroethylene (PTFE), which has excellent chemical resistance, high temperature resistance and low friction characteristics, and can maintain good sealing performance in various harsh working environments.

[0040] Please continue reading. Figures 1-6 In this embodiment, a connecting block 41 is symmetrically arranged on the top of the sludge tank 4. The connecting block 41 is V-shaped. When the positioning cylinder 32 extends, it will be embedded in the connecting block 41 to achieve a snap-fit ​​fixation.

[0041] Furthermore, symmetrically arranged door modules 42 are provided between the connecting blocks 41 for sealing the sludge tank 4. The door modules 42 are also provided with snap-fit ​​grooves. When the switch cylinder 33 extends out, it connects with the snap-fit ​​grooves and then drives the door modules 42 to open and close, thereby realizing the feeding and sealing of the sludge tank 4.

[0042] Specifically, sealing surfaces 43 are symmetrically arranged on both sides of the door module 42. The sealing surfaces 43 are used to fit the sealing strip 34 to achieve the sealing of the entire sludge tank 4.

[0043] Please continue reading. Figures 1-6 In this embodiment, a lifting cylinder assembly 5 is also included. The lifting cylinder assembly 5 is symmetrically arranged on both sides of the material equalization assembly 2 and is used to connect the sealing assembly 3 and the sludge tank 4. The entire device can be hoisted and fixed through the cylinder base.

[0044] Please continue reading. Figures 1-6 In this embodiment, the sludge tank 4 is equipped with a weighing block 6, and weighing sensors are symmetrically arranged inside the weighing block 6. Multiple workstations can be set up to cooperate with the transfer trolley 7 (Automated Guided Vehicle, AGV) to transfer empty and full tanks alternately.

[0045] Furthermore, the bottom of the sludge tank 4 is also equipped with movable floor strips. (By controlling the movement of each movable floor strip, the resting angle α of the accumulated material at the feed end can be adjusted to achieve the required bed resting angle. During discharge, the movable floor strips can move forward completely or partially to discharge the material. If all the floor strips move forward, a portion can be set to retract the material. For details, please refer to the authorized patent, patent number CN114521497B, which is prior art and will not be elaborated further.) The resting angle can be adjusted, thereby further improving the volume utilization rate of the sludge tank 4.

[0046] Working principle:

[0047] The entire workstation includes the material receiving station, the empty box station, and the full box station:

[0048] Receiving station: Receiving buffer, mainly connects the materials of the upstream equipment and conveys them to the sludge box 4 through the feeding component 1. The material leveling component 2 is used to reduce the peaks so that the sludge in the sludge box 4 is evenly spread to both sides. During this period, the weighing pier 6 under the sludge box 4 monitors the filling status of the sludge box 4 to ensure the utilization rate of the sludge box 4.

[0049] Empty container station: Empty container buffer, mainly used to buffer empty sludge containers 4, and empty containers are unloaded to this station by hooklift truck 8;

[0050] Full container station: Full container outbound transport, mainly used to buffer full sludge containers 4, and at the same time facilitates the transfer trolley 7 to drag the full sludge containers 4 to the hooklift truck 8 for outbound transport.

[0051] In specific work:

[0052] The sludge transported by the upstream equipment enters the shaftless screw conveyor 13 from the feed hopper 11. The shaftless screw conveyor 13 is then driven by a motor on one side to alternately and bidirectionally transport the sludge. The weight of the material falling and the alternating feeding time are monitored by the weighing sensor built into the load-bearing pier below the sludge tank 4 to ensure the consistency of the amount of sludge at the two falling points entering the sludge tank 4. The lifting cylinder assembly 5 is connected by multiple sets of symmetrically arranged cylinders to realize the lifting of the feeding assembly 1, the equalizing assembly 2 and the sealing assembly 3. This ensures that the sealing frame 31 of the sealing assembly 3 can be tightly fitted with the upper surface of the sludge tank 4 below, ensuring that the entire conveying process is carried out in a closed manner.

[0053] During the bonding process, the positioning cylinder 32 and the connecting block 41 on the sludge tank 4 are first locked together. Then, the switching cylinder 33 in the sealing frame 31 opens the switching door module 42 on the top of the sludge tank 4. Then, the lifting module 22 lowers the servo motor leveling system 21 and the feeding blade 23 to smooth and level the sludge pile during the falling process. At the same time, according to the torque feedback, the leveling blade is slowly moved upward according to the torque gradient, thereby effectively improving the volume utilization rate of the sludge tank 4.

[0054] After the sludge container 4 reaches the preset weight of the first stage, the system will send a prompt signal to the transfer personnel. After reaching the preset value of the second stage, the system will dispatch the AGV transfer vehicle 7 to transfer the full container to the empty container station for transfer. Then the AGV transfer vehicle 7 will transfer the empty container to the receiving station to complete one conveying cycle.

[0055] In addition, the hooklift box is equipped with a hydraulic power unit, which is connected to the hydraulic drive of the hooklift truck 8. The bottom of the hooklift box is equipped with a hydraulic slide, and through the hydraulic drive of the hooklift truck 8, all the sludge in the sludge tank 4 can be poured out without manual intervention.

[0056] In addition, the entire storage and transportation device and AGV transfer trolley 7 are monitored by a PLC controller to regulate the feeding, transfer and unloading processes, and prevent interference in the operating path or empty workstations: AGV transfer trolley 7 will automatically transport empty sludge boxes 4 from the empty box workstation to the receiving workstation. When the sludge boxes 4 at the receiving workstation are full, the system will notify AGV transfer trolley 7 to transport the full boxes at the receiving workstation to the full box workstation, waiting for the hooklift truck 8 to transport the box out; at the same time, AGV transfer trolley 7 continues to go to the empty box workstation to transfer the empty boxes to the receiving workstation, and hooklift truck 8 will place the emptied sludge boxes 4 at the empty box workstation and then go to the full box workstation to load the full boxes out.

[0057] Through the above technical solution, this application analyzes the states of empty, packed, and full containers, and operates in a fully automated manner. The entire operation is divided into process segments, and each process segment has a dedicated component. Different components can be used to complete material receiving and buffering, mud storage and transportation, and dispatching for external transport in sequence without the need for manual intervention. Sensors calculate the time when the material is full and give a signal to the transfer driver in advance to indicate the time when the container is full, thereby achieving precise dispatching and effectively reducing the waiting time for external transport.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
