Description

Technical Field

[0001] This utility model relates to the technical fields of geological drilling, building construction, and sewage treatment, and more specifically to an integrated skid-mounted one-button intelligent and efficient waste slurry treatment device. Background Technology

[0002] In industrial production processes, especially in fields such as geological drilling, construction, and wastewater treatment, the treatment of waste slurry has always been a critical step. Traditional waste slurry treatment equipment typically suffers from the following problems:

[0003] Large and dispersed equipment: Traditional waste slurry treatment equipment often consists of multiple independent parts, occupying a large area, and is complex to install and debug, making it difficult to adapt to the needs of on-site miniaturization and modularization.

[0004] Manual operation relies on experienced operators: Many devices rely on operators' experience to manually adjust the feed pressure, which can easily lead to excessively fast feed speed and instantaneous pressure increase, resulting in "spraying" phenomenon. This not only affects processing efficiency but may also pose safety hazards.

[0005] Low level of automation: Traditional equipment has a limited level of automation, making it impossible to achieve remote monitoring and intelligent control. This results in high on-site labor intensity, unstable processing, and difficulty in meeting the waste slurry treatment needs under different geological conditions.

[0006] High maintenance costs: Due to the dispersed nature of the equipment and the complex connections between the components, maintenance and repair are difficult, increasing the operating costs of the equipment.

[0007] To address the aforementioned issues, there is an urgent market need for an integrated skid-mounted, one-button intelligent and efficient waste slurry treatment device that can achieve a high degree of integration, automation, and intelligence, reduce on-site labor intensity, improve processing efficiency and safety, and simultaneously reduce equipment footprint and maintenance costs. Utility Model Content

[0008] In view of this, the present invention provides an integrated skid-mounted one-button intelligent and efficient waste slurry treatment device, which aims to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An integrated skid-mounted, one-button intelligent and efficient waste slurry treatment device includes:

[0011] Skid-mounted base;

[0012] The press body has a mounting bracket fixed on the skid base and located in the center of the skid base. One end of the press body has a pressing inlet and a water outlet, and the other end has a hydraulic cylinder for applying pressure.

[0013] A screw feeding mechanism is installed on the skid-mounted base and located on one side of the press body. The screw feeding mechanism is powered by a variable frequency feed pump and realizes screw conveying feeding. The feed pipe of the screw feeding mechanism is connected to the press feed port.

[0014] A variable frequency pressing mechanism is installed on the skid-mounted base and located on the side of the press body relative to the screw feeding mechanism. The variable frequency pressing pump of the variable frequency pressing mechanism is connected to the diaphragm filter plate of the press body through a pipeline and is used to deliver pressing medium to the pressing chamber of the diaphragm filter plate.

[0015] The hydraulic station and the PLC automatic control cabinet are both mounted on the skid-mounted base and are located at one end of the hydraulic cylinder near the body of the press, respectively arranged on both sides of the hydraulic cylinder.

[0016] Through the above technical solution, this utility model integrates core components such as the press body, screw feeding mechanism, variable frequency pressing mechanism, hydraulic station, and PLC automatic control cabinet onto a skid-mounted base, greatly reducing the equipment's footprint and facilitating transportation, installation, and commissioning. It can quickly respond to the waste slurry treatment needs of different sites, and is particularly suitable for on-site miniaturized and modular applications. The screw feeding mechanism, powered by a variable frequency feed pump, enables screw conveying of material, while the variable frequency pressing mechanism's pump delivers pressing media to the diaphragm filter plate pressing chamber. Combined with the PLC automatic control cabinet, this achieves automated control of the waste slurry treatment process, reducing manual operation intensity and error risks, and improving processing efficiency and stability.

[0017] Preferably, in the aforementioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, a screw conveyor shaft is installed inside the feed pipeline. The screw conveyor shaft is powered by a variable frequency feed pump, which is connected to one end of the feed pipeline. A feed pipeline check valve, a feed pipeline electric vent valve, and a feed pipeline pressure transmitter are sequentially installed between the other end of the feed pipeline and the pressing inlet. The screw conveyor shaft inside the feed pipeline, powered by a variable frequency feed pump, enables precise control of the waste slurry feed speed and flow rate, preventing excessively fast feed speeds from causing a sudden pressure increase and resulting in "spraying" phenomena, thus improving the stability and safety of the feeding process. The sequential installation of the feed pipeline check valve, feed pipeline electric vent valve, and feed pipeline pressure transmitter allows for real-time monitoring of the feed pressure and feedback to the control system. PLC control technology enables intelligent adjustment of the feeding process, further optimizing the feeding operation and enhancing the automation and intelligence level of the equipment.

[0018] Preferably, in the above-mentioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the feed pipeline has a waste slurry inlet. The presence of a waste slurry inlet on the feed pipeline facilitates the input and delivery of waste slurry, allowing it to smoothly enter the feed pipeline and be transported to the press body for processing. This ensures the smooth operation of the waste slurry treatment process and improves the practicality and convenience of the equipment.

[0019] Preferably, in the above-mentioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the pump outlet of the variable frequency pressing pump is connected to a pressing pipeline check valve. Connecting the pump outlet of the variable frequency pressing pump to the pressing pipeline check valve effectively prevents backflow of the pressing medium during transportation, ensuring that the pressing medium can be stably and unidirectionally transported to the pressing chamber of the diaphragm filter plate, improving the stability and reliability of the pressing process, and extending the service life of the equipment.

[0020] Preferably, in the aforementioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the variable frequency pressing mechanism further includes a main media pipeline connected to the pump outlet of the variable frequency pressing pump, and multiple branch media pipelines connected in parallel between the main media pipeline and the multiple diaphragm filter plates. This structural design enables uniform distribution and efficient delivery of the pressing media, ensuring that each diaphragm filter plate receives a sufficient and stable supply of pressing media, thereby improving the uniformity and consistency of the pressing effect and enhancing the quality of waste slurry treatment.

[0021] Preferably, in the aforementioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, an electric press return valve is installed at one end of the main media pipeline, and a press pressure transmitter is installed at the other end of the main media pipeline. This allows for real-time monitoring of pressure changes during the pressing process and enables precise pressure control through the control system. At the end of the pressing process, the electric press return valve automatically opens to release the remaining pressing medium, preventing damage to the equipment and pipelines due to excessive pressure and facilitating the start of the next work cycle.

[0022] Preferably, in the above-mentioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the branch media pipeline is a high-pressure pressing hose. The branch media pipeline uses a high-pressure pressing hose, which has good high-pressure resistance and flexibility, can withstand high pressure during the pressing process, ensures stable delivery of the pressing media, and is convenient for installation, disassembly, and maintenance. It adapts to different working environments and equipment layout requirements, improving the reliability and maintainability of the equipment.

[0023] Preferably, in the aforementioned integrated skid-mounted, one-button intelligent high-efficiency waste slurry treatment device, an intelligent pressure switch is installed on the hydraulic cylinder. The intelligent pressure switch on the hydraulic cylinder can monitor the working pressure of the hydraulic cylinder in real time and feed the pressure signal back to the control system. The system can automatically adjust the pressure of the hydraulic cylinder according to the set working pressure range, preventing equipment failure or damage due to excessively high or low pressure, improving the stability and safety of equipment operation, and extending the service life of the equipment.

[0024] Preferably, in the aforementioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the PLC automatic control cabinet is equipped with an intelligent IoT touch screen and a mouse controller. The PLC automatic control cabinet provides operators with an intuitive and convenient human-machine interface. Operators can use the touch screen and mouse controller to start, stop, set parameters, and monitor the status of the equipment, and can view the equipment's operating data and working status in real time. This achieves intelligent control and remote monitoring of the waste slurry treatment process, improving the automation level and ease of operation of the equipment.

[0025] Preferably, in the aforementioned integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, the variable frequency feed pump and the variable frequency pressing pump are sequentially controlled by the same frequency converter. This sequential control of the feed pump and pressing pump by the same frequency converter enables synchronized and coordinated operation of the feeding and pressing processes, ensuring that the feeding speed and pressing pressure are matched during waste slurry treatment. This improves the continuity and synergy of the entire treatment process, further optimizes the waste slurry treatment effect, and also reduces the equipment's energy consumption and operating costs.

[0026] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated skid-mounted one-button intelligent high-efficiency waste slurry treatment device, which has the following beneficial effects:

[0027] 1. High integration and convenience: The equipment is highly integrated on the skid-mounted base, which reduces the floor space, facilitates transportation, installation and commissioning, and adapts to the needs of miniaturization and modularization on site.

[0028] 2. Automation and intelligence: Through PLC automatic control cabinet and frequency conversion technology, the automated operation and intelligent control of waste slurry treatment are realized, which reduces the intensity of manual operation and the risk of error, and improves the processing efficiency and stability.

[0029] 3. High-efficiency pressing and optimized control: The use of variable frequency feed pumps and variable frequency pressing pumps, combined with precise pressure monitoring and feedback adjustment, ensures that the pressing process is efficient and stable. Parameters can be flexibly adjusted according to different waste pulp properties and needs to meet diverse treatment requirements.

[0030] 4. Safety and Reliability: Intelligent pressure switches are installed on the hydraulic cylinders to prevent damage to the equipment due to abnormal pressure; high-pressure pressing hoses and check valves are used to improve the safety and reliability of the equipment under high-pressure working conditions.

[0031] 5. Reduced operating costs: Integrated design reduces equipment maintenance workload; the application of frequency conversion technology optimizes energy consumption and reduces long-term operating costs of the equipment. Attached Figure Description

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] See appendix Figure 1 To be continued Figure 3 This utility model discloses an integrated skid-mounted, one-button intelligent and efficient waste slurry treatment device, comprising:

[0050] Skid-mounted base 1;

[0051] The press body 2 has a mounting bracket 21 fixed on the skid base 1 and located in the center of the skid base 1. One end of the press body 2 has a pressing inlet 22 and a water outlet 23, and the other end has a hydraulic cylinder 24 for applying pressure.

[0052] The screw feeding mechanism 3 is installed on the skid-mounted base 1 and located on one side of the press body 2. The screw feeding mechanism 3 is powered by the variable frequency feed pump 31 and realizes screw conveying feeding. The feed pipe 32 of the screw feeding mechanism 3 is connected to the press feed port 22.

[0053] The variable frequency pressing mechanism 4 is installed on the skid-mounted base 1 and is located on the side of the press body 2 relative to the screw feeding mechanism 3. The variable frequency pressing pump 41 of the variable frequency pressing mechanism 4 is connected to the diaphragm filter plate of the press body 2 through a pipeline and is used to deliver pressing medium to the pressing chamber of the diaphragm filter plate.

[0054] Hydraulic station 5 and PLC automatic control cabinet 6 are both installed on skid-mounted base 1 and are located at one end of hydraulic cylinder 24 near the body of press 2, and are respectively arranged on both sides of hydraulic cylinder 24.

[0055] To further optimize the above technical solution, a screw conveyor shaft is provided in the feed pipe 32. The screw conveyor shaft is powered by a variable frequency feed pump 31. The variable frequency feed pump 31 is connected to one end of the feed pipe 32. A feed pipe check valve 33, a feed pipe electric vent valve 34, and a feed pipe pressure transmitter 35 are installed sequentially between the other end of the feed pipe 32 and the pressing inlet 22.

[0056] The electric vent valve 34 in the feed pipeline serves two purposes: first, to release air from the feed system; second, to discharge residual waste slurry from the feed pipeline 32 after waste slurry treatment; and third, to flush the pipeline.

[0057] To further optimize the above technical solution, the feed pipeline 32 has a waste slurry inlet 36.

[0058] In this embodiment, electric power is preferred for feeding, which can solve the problems of insufficient power and low efficiency of pneumatic diaphragm pumps, and the need for a matching air compressor; the variable frequency feed pump 31 is preferably equipped with a reducer screw pump to reduce screw pump wear; the screw pump adopts PID variable frequency control, and the feeding working pressure is 0.6-0.8MPa. The PID controls the speed of the variable frequency feed pump 31 by real-time monitoring of the feeding pressure feedback.

[0059] To further optimize the above technical solution, a check valve 42 for the pressing pipeline is connected to the pump outlet of the variable frequency pressing pump 41. The pressing working pressure is 0.8-1.2MPa. The speed of the variable frequency pressing pump 41 is controlled by PID variable frequency feedback. According to the site requirements, the pressure and time of feeding and pressing can be set to adjust the solid liquid content after pressing and dewatering, so as to meet the needs of waste slurry treatment effect and capacity in different geological drilling sites.

[0060] To further optimize the above technical solution, the variable frequency pressing mechanism 4 also includes a main medium pipeline 43 connected to the pump outlet of the variable frequency pressing pump 41, and multiple branch medium pipelines 44 connected in parallel between the main medium pipeline 43 and multiple diaphragm filter plates.

[0061] To further optimize the above technical solution, a pressing electric return water valve 45 is installed at one end of the main medium pipeline 43, and a pressing pressure transmitter 46 is installed at the other end of the main medium pipeline 43. After pressing, the pressing electric return water valve 45 automatically opens; however, during feeding, the pressing electric return water valve 45 automatically remains closed.

[0062] To further optimize the above technical solution, the branch medium pipeline 44 is a high-pressure pressing hose.

[0063] To further optimize the above technical solution, an intelligent pressure switch 25 is installed on the hydraulic cylinder 24. In this embodiment, the system working pressure is set, that is, the working pressure of the intelligent pressure switch 25 is set to 10-13 MPa, and the system automatically adjusts the pressure according to the feeding and cylinder working status.

[0064] To further optimize the above technical solution, the PLC automatic control cabinet 6 is equipped with an intelligent IoT touch screen 61 and a mouse controller 62.

[0065] To further optimize the above technical solution, the variable frequency feed pump 31 and the variable frequency pressing pump 41 are controlled sequentially by the same frequency converter, controlling the variable frequency feed pump 31 and the variable frequency pressing pump 41 one after the other.

[0066] The variable frequency press pump 41 adopts a vertical structure, which improves integration and reduces size. In this embodiment, the variable frequency press pump 41 is a stainless steel multi-stage centrifugal pump. The core component of this pump is a multi-stage centrifugal impeller. Through the progressive pressurization of the multi-stage impeller, higher pressure can be generated to meet the high-pressure delivery requirements of the pressing medium in the pressing process. The use of stainless steel not only gives the pump good corrosion resistance, enabling it to resist corrosive substances that may be present in the waste slurry, extending the pump's service life and reducing equipment maintenance costs, but also provides a smooth surface that is not prone to bacterial and dirt growth, meeting environmental and hygiene requirements. Furthermore, the multi-stage centrifugal pump has a compact structure and occupies little space, making it suitable for integration into a skid-mounted base. When used with a frequency converter, it can achieve precise adjustment of the pressing medium delivery rate, ensuring the stability and consistency of the pressing process, high efficiency, and energy saving, reducing equipment energy consumption. In addition, the pump has no complex vulnerable parts inside, making maintenance relatively simple, and the standardized design makes repair and replacement of parts more convenient.

[0067] In this embodiment, a water collection tank 11 is also installed on the skid-mounted base 1, located below the press body 2, to collect the liquid that leaks from the filter cloth during the pressing and dewatering process, so as to avoid polluting the ground.

[0068] The press body 2 provided in this embodiment is a conventional press structure, consisting of a fixed plate, a tail plate, a filter plate, a diaphragm filter plate, a head plate, and a movable pressure plate, etc., which will not be described in detail here.

[0069] In this embodiment, the PLC automatic control cabinet 6 can be a conventional control cabinet or an explosion-proof control cabinet. Correspondingly, other structural components in this embodiment are all explosion-proof products to meet the usage requirements.

[0070] In this embodiment, the pressure of the feed pipeline 32 is collected in real time, and the operating frequency of the variable frequency feed pump 31 is adjusted by PID control technology to ensure that the feed speed is stable when processing different waste slurry properties. This can effectively avoid the phenomenon of material spraying caused by manual adjustment based on experience, which can lead to instantaneous pressure increase.

[0071] By combining PLC control technology and HMI configuration technology, the automatic control of processes such as filter plate clamping, pressure holding, primary feeding filtration, secondary diaphragm pressing, and filter plate loosening is realized, further improving the automation and intelligence level of the waste slurry treatment device and reducing on-site labor intensity.

[0072] The process parameters are monitored in real time. By adjusting the pressure and time of the primary filtration and secondary diaphragm pressing dewatering, combined with PID feedback frequency conversion control technology and one-button start, the entire process of waste slurry treatment can be automated. This meets the needs of different geological drilling sites for waste slurry treatment effects and capabilities. It also has two control modes, manual and automatic, which can be switched freely, and supports online remote control and maintenance.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
