Description

Technical Field

[0001] This application relates to the technical field of sludge treatment, and in particular to a sludge silo unloading and discharge device. Background Technology

[0002] In the sludge treatment industry, with increasingly stringent environmental protection requirements and gradually increasing sludge production, the storage and unloading processes have become crucial. Effective sludge unloading devices can improve sludge treatment efficiency, reduce manual intervention, and minimize environmental impact. A well-designed unloading system ensures smooth sludge transport, preventing blockages during storage and guaranteeing the normal operation of the entire sludge treatment process. Simultaneously, effective treatment of harmful gases generated during sludge storage and loading is key to protecting worker health and meeting environmental requirements. With industrial development and accelerated urbanization, the demands on the performance and intelligence of sludge treatment equipment are also rising.

[0003] In traditional sludge unloading processes, the positioning of transport vehicles under the sludge silo relies primarily on the driver's experience and visual estimation, or requires assistance from ground control personnel. This method is not only inefficient but also poses significant safety hazards. Deviations in the vehicle's parking position can lead to misalignment between the unloading port and the vehicle's inlet, easily causing material spillage accidents. This results in material loss and environmental pollution, as well as increased cleanup costs and safety risks.

[0004] Furthermore, there is a lack of effective coordination between material level management within the waste material silo, the start-up and shutdown of unloading equipment, and the loading and unloading rhythm of transport vehicles. Operators need to perform independent operations and judgments in multiple aspects, such as transport vehicle positioning, material level monitoring, and equipment control. The entire system has a low degree of automation, relies heavily on manual labor, and not only is the workload high, but it is also difficult to ensure the standardization and stability of the work process. Utility Model Content

[0005] In order to improve the efficiency of unloading and discharging sludge from a sludge silo, this application provides a sludge silo unloading and discharging device.

[0006] The sludge silo unloading and discharge device provided in this application adopts the following technical solution: A sludge silo unloading and discharging device includes a workshop, a controller, and at least one sludge silo located above the workshop. The workshop has at least one parking space, and the discharge port of the sludge silo is located corresponding to the parking space. The sludge silo is equipped with a pushing mechanism, a sludge level detector, and a conveying mechanism. Four pressure sensors are pre-embedded below the tire parking point of the transport vehicle at each parking space. The detection area of ​​the pressure sensors matches the wheelbase and track width of the transport vehicle. The sludge level detector, the conveying mechanism, and the pressure sensors are all signal-connected to the controller.

[0007] By adopting the above technical solution and setting up a corresponding layout of multiple waste bins and multiple parking spaces, parallel processing of unloading operations was achieved, improving overall operational efficiency. The matching design of pressure sensors with the wheelbase and track width of the transport vehicles ensured the accuracy of the transport vehicles' parking positions, providing a precise positioning basis for subsequent automated unloading. The centralized control of all components by the controller formed a complete automated unloading and discharging operation system, effectively reducing the intensity of manual operation.

[0008] Preferably, the pushing mechanism includes a hydraulic component, a push plate, and a plurality of push heads disposed on the push plate. The output end of the hydraulic component is connected to the push plate to drive the push plate to reciprocate along the discharge direction of the waste material. The tip of the push head is positioned toward the discharge direction of the waste material hopper.

[0009] By adopting the above technical solution, the material pushing mechanism uses hydraulic drive combined with a pusher plate with multiple push heads, which effectively enhances the arch breaking ability.

[0010] Preferably, the waste bin is provided with an installation plate, and a discharge port is provided on the side of the installation plate away from the pushing mechanism. The length direction of the discharge port is perpendicular to the movement direction of the pushing plate, and the lower end of the discharge port is connected to the inlet of the conveying mechanism.

[0011] By adopting the above technical solutions, the blockage of materials at the transfer point is effectively avoided, ensuring the continuity of material transportation.

[0012] Preferably, a material level detector is installed on the top of the workshop corresponding to each parking space, and the material level detector is connected to the controller via signal.

[0013] By adopting the above technical solution and installing material level detectors above the parking spaces, real-time monitoring of the loading process is achieved. This design can accurately grasp the loading status of transport vehicles and effectively prevent overloading or underloading.

[0014] Preferably, an electric door is installed at the entrance of the workshop, and the electric door is connected to the controller signal.

[0015] By adopting the above technical solution, the signal connection with the controller enables the access control system to automatically open and close according to the work process, which not only ensures the enclosure of the work area, but also improves the operating efficiency.

[0016] Preferably, an infrared sensor is installed at the workshop exit, and the infrared sensor is connected to the controller signal.

[0017] By adopting the above technical solution and monitoring the departure status of transport vehicles in real time, the gate can be closed in a timely manner, effectively maintaining environmental control inside the workshop.

[0018] Preferably, the workshop is also equipped with an exhaust and deodorization mechanism, which includes an activated carbon filter installed on the top of the workshop; the exhaust and deodorization mechanism is controlled and connected to the controller.

[0019] By adopting the above technical solution, the exhaust and deodorization mechanism, combined with the activated carbon filter, effectively solves the odor pollution problem in the sludge treatment process. The installation location at the top of the workshop ensures the timely collection and treatment of harmful gases, while the activated carbon filter provides reliable purification.

[0020] Preferably, the workshop is equipped with a voice prompt device, which is located near the parking space and connected to the controller signal.

[0021] By adopting the above technical solutions, clear operating instructions can be provided for operators, effectively reducing the risk of misoperation.

Through the matching design of the pre-embedded pressure sensor array and the wheelbase of the transport vehicle, the precise positioning during the unloading process was ensured, effectively preventing material spillage. 3. A comprehensive operational support system has been established, which integrates multiple functions such as material level monitoring, voice prompts, and ventilation and deodorization, thereby improving operational safety while effectively controlling environmental impact.

Detailed Implementation

[0025] The following combination Figures 1-2 This application will be described in further detail.

[0026] This application discloses a sludge silo unloading and discharge device.

[0027] Reference Figure 1 and Figure 2 A sludge silo unloading and discharging device includes a workshop 1, a sludge silo 2, a pushing mechanism 3, a sludge level detector 4, a controller, and a conveying mechanism 5. At least two sludge silos 2 are provided, both located above the workshop 1, which has at least one parking space. The pushing mechanism 3 is located inside the sludge silo 2 to assist in sludge unloading. The sludge level detector 4 is located on the inner wall of the sludge silo 2 and can monitor the sludge level in real time. The controller is electrically connected to the sludge level detector 4, the pushing mechanism, and an external feed valve, and can control feeding and pushing actions based on signals provided by the sludge level detector 4. The conveying mechanism 5 is located inside the sludge silo 2 and is used to transport the sludge to a transport vehicle 100 within the workshop 1. The controller can control the operating status of the pushing mechanism 3 and the conveying mechanism 5 based on signals from the sludge level detector 4, achieving automated control of sludge unloading and discharging, improving operational efficiency, and reducing manual intervention.

[0028] The sludge silo 2 is generally rectangular in shape, with an inlet at the top that connects to the outlet 7 of an external material feeding mechanism. The pushing mechanism 3 includes a hydraulic component 31, a pusher plate 32, and multiple pushers 33 mounted on the pusher plate 32. The hydraulic component 31 is located on the outside of the sludge silo 2, with its output end inside the silo silo 2. The pusher plate 32 is generally rectangular, with its longitudinal plane perpendicular to the bottom plate of the sludge silo 2. The pusher plate 32 is located on the side of the sludge silo 2 furthest from the inlet. The pusher plate 32 is typically made of steel plate with sufficient thickness and strength to prevent deformation during the pushing process. Multiple pushers 33 are also mounted on the longitudinal plane of the pusher plate 32. Each pusher 33 can be conical with its tip extending towards the sludge discharge direction, thus more effectively breaking up sludge arches. The hydraulic component 31 is installed on the inner wall of the sludge silo 2, and its output end is fixedly connected to the pushers 33. When the hydraulic assembly 31 is working, its output end pushes the pusher head 33, which in turn moves the pusher plate 32. As the pusher plate 32 moves, the multiple pushers 33 can directly break up the already formed sludge arch bridge and evenly assist in unloading, improving the smoothness of unloading.

[0029] The mud level detector 4 can be configured as a radar wave sensor or an ultrasonic sensor. The radar wave sensor uses the principle of radar wave reflection to measure the material level, offering advantages such as high measurement accuracy and immunity to environmental influences. The ultrasonic sensor determines the material level by emitting ultrasonic waves and receiving reflected waves. The mud level detector 4 is installed at the top opening of the sludge hopper 2 and probes the material level downwards, enabling real-time monitoring of the material level within the sludge hopper 2 and providing accurate level signals. The controller sets the upper limit for the material level in each sludge hopper 2. When the material level in a sludge hopper 2 exceeds the set upper limit, the controller stops feeding into the sludge hopper 2 and simultaneously switches the feeding to another sludge hopper 2 whose internal material level has not reached the upper limit via a valve, preventing overflow and achieving precise control of the feeding. Furthermore, if the material level in a sludge hopper 2 exceeds the maximum loading capacity of a single transport vehicle 100, the transport vehicle 100 is instructed to continue loading; if the material level in a sludge hopper 2 is insufficient, the driver is prompted to proceed to the discharge port 7 of another sludge hopper 2.

[0030] An installation plate 6 is also installed inside the waste material bin 2, with its longitudinal plane parallel to the bottom surface of the waste material bin 2. The installation plate 6 is typically made of sheet metal and possesses a certain strength and rigidity. An elongated discharge port 7 is provided on the installation plate 6 along a direction perpendicular to the movement direction of the pusher plate 32, and the width of the discharge port 7 covers the effective pushing width of the pusher plate 32. Through the reciprocating motion of the pushing mechanism 3, the material can be horizontally pushed above the discharge port 7.

[0031] The conveying mechanism 5 is installed on the mounting plate 6 near the bottom of the workshop 1, and the inlet and outlet 7 of the conveying mechanism 5 are sealed together. The inlet of the conveying mechanism 5 is connected to the lowest end of the outlet 7 to receive materials falling from the outlet 7. The outlet of the conveying mechanism 5 faces the parking space in the workshop 1 to realize the loading of the transport vehicle 100. In this embodiment, the clinker mechanism is set as a screw conveyor, including a screw shaft, screw blades and a shell. The screw shaft rotates under the drive of the motor, driving the screw blades to transport the material to the outlet.

[0032] A non-contact level sensor 10 is installed on the top of workshop 1 for each parking space. In this embodiment, the non-contact level sensor 10 is configured as a multi-point radar wave sensor or an ultrasonic sensor. The level sensor 10 is electrically connected to the controller and is used to monitor the loading amount of the corresponding transport vehicle 100. The radar wave level sensor 10 above each parking space measures the height of the sludge loaded in the transport vehicle 100. When the height of the sludge loaded in the transport vehicle 100 reaches the maximum loading height of the transport vehicle 100, the controller closes the conveying mechanism 5 near that transport vehicle 100.

[0033] Four pressure sensors 8 are pre-embedded beneath the intended parking points of the transport vehicle 100 in each parking space. The detection area formed by these four sensors matches the wheelbase and track width of the target transport vehicle 100. When the transport vehicle 100 enters the parking space, the controller monitors the pressure data from the four sensors in real time. By setting a load threshold through the controller, the controller determines that the transport vehicle 100 is in place only when the readings of all four sensors simultaneously exceed the preset load threshold, thus eliminating interference such as people stepping on it. When it is detected that the transport vehicle 100 has been loaded and all the pressure sensor 8 signals in the same parking space have disappeared (i.e., the transport vehicle 100 has left), the controller will issue a command to automatically open the retractable door of workshop 1 to facilitate the exit of the transport vehicle 100.

[0034] Preferably, an infrared sensor 11 connected to the controller signal is also provided on the outside of workshop 1. When the controller detects that the transport vehicle 100 has completely left workshop 1, it immediately drives the retractable gate to close automatically, thereby ensuring the safe passage of the transport vehicle 100 and timely closing the space of workshop 1, effectively maintaining internal environmental control and saving energy.

[0035] To effectively control the odor and toxic gases emitted during sludge storage and loading, protect the health of workers, and meet environmental protection requirements, a ventilation and deodorization system 12 is installed in workshop 1. This system continuously removes toxic, harmful, and odorous gases emitted from the sludge. The system is equipped with a high-efficiency activated carbon air filter to adsorb and purify the collected exhaust gases, thereby effectively preventing pollution to the interior and surrounding environment of workshop 1.

[0036] Workshop 1 is also equipped with multiple voice prompt devices 13 connected to the controller signals, with each device positioned near a parking space. These voice prompt devices 13 provide full-process voice guidance and status alerts, including: notifying the driver to prepare after the pressure sensor 8 confirms the transport vehicle 100 is in place; guiding the transport vehicle 100 to move during the switching of the waste material hopper 2; and immediately issuing alarms in case of system malfunctions or safety risks. By replacing manual commands with clear voice instructions, operational efficiency and safety are effectively improved.

[0037] The implementation principle of the sludge silo unloading and discharging device in this embodiment is as follows: First, based on the monitoring data of the sludge level detector 4 inside the sludge silo 2, a silo 2 with sufficient material level is selected for operation. Then, the transport vehicle 100 is positioned by the pressure sensor 8. After the transport vehicle 100 is in position, the pushing mechanism 3 starts working under hydraulic drive. The push plate 32 drives multiple push heads 33 to reciprocate, pushing the sludge towards the elongated discharge port 7 at the bottom of the silo. The sludge falls through the discharge port 7 into the conveying mechanism 5 and is transported to the waiting transport vehicle 100 below. During the loading process, the radar wave level detector 10 arranged above the vehicle position monitors the material level height inside the vehicle in real time. When the preset loading amount is reached, the system automatically stops the pushing and conveying operation and provides a voice prompt to the driver indicating that the operation is complete. Throughout the process, the exhaust and deodorization mechanism 12 runs continuously to collect and purify the generated harmful gases, ensuring that the working environment meets environmental protection requirements. This system realizes fully automated operation from guiding the transport vehicle 100, precise positioning, automatic loading to environmental treatment.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
