Description

Technical Field

[0001] This utility model relates to the field of desliming machine technology, and specifically to a desliming machine operating system. Background Technology

[0002] Currently, a large amount of sludge is generated during wastewater treatment. Sludge is a paste-like substance with high water content, high viscosity, loose and porous structure, and accompanied by odorous gases. Wastewater treatment plants dewater the sludge before further processing, which effectively reduces the transportation costs of subsequent treatment. In existing technology, sludge dewatering machines, as a type of continuously operating sludge treatment equipment, are widely used in wastewater treatment due to their low sludge water content, stable operation, low energy consumption, relatively simple control and management, and convenient maintenance.

[0003] Because the filter cloth of the desliming machine is in constant contact with the filter cake and filtrate, and because it operates under high pressure, many solid particles accumulate on it. Excessive accumulation of these particles affects the filter cloth's permeability; therefore, frequent cleaning is necessary. Currently, the cleaning process typically involves inserting flushing pipes with nozzles into both sides of the desliming machine. These pipes are connected to a pressure pump, providing high-pressure water. The high-pressure water is then sprayed through the nozzles to clean the filter cloth. Additionally, the desliming machine usually requires the use of an air compressor. The compressed air from the air compressor drives the pneumatic tensioning device, ensuring the filter belt or filter plate is evenly stressed before dewatering. Insufficient pressure can cause the filter belt to loosen, leading to misalignment or sludge leakage. The desliming machine can only operate once the pressure provided by the air compressor reaches the level required for normal operation.

[0004] In existing technologies, the water used for cleaning filter cloths requires high quality and a large volume of water. To save costs, companies currently use treated wastewater that can be discharged into the river as the water for rinsing the filter cloths. However, wastewater still contains impurities. When rinsing the filter cloths is not required, the booster pump needs to be turned off to stop the water supply. Even after the booster pump is turned off, the water in the pipeline will still flow through the rinsing pipes. Without the high pressure provided by the booster pump, impurities in the wastewater are more likely to accumulate in the nozzles during water flow. Long-term use can accelerate nozzle clogging, requiring frequent nozzle cleaning and increasing labor costs. Furthermore, the existing booster pump's water supply and the air compressor's air supply are not connected to an automatic control system and both require manual start-up, which is cumbersome and increases labor costs. Utility Model Content

[0005] This invention provides a desliming machine operating system, the purpose of which is to reduce the speed at which nozzles become clogged.

[0006] This utility model is achieved through the following technical solution: a desliming machine operating system, including a desliming machine, a pressure pump and a flushing pipe; a nozzle is installed on the flushing pipe, the outlet end of the pressure pump is connected to the flushing pipe through a water pipe, and the inlet end of the pressure pump is connected to a water source; a water valve is installed on the water pipe connecting the flushing pipe and the pressure pump.

[0007] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0008] Because the booster pump is usually installed in a dedicated pump room, which is a certain distance from the sludge dewatering machine, the water pipe between the booster pump and the flushing pipe is relatively long. When the booster pump is turned off, there is still a large amount of water in the water pipe. The water in the water pipe will continue to flow towards the flushing pipe. Since there is no pressure provided by the booster pump at this time, the water flow is slow. The water used to flush the filter cloth is usually treated wastewater from the plant. However, wastewater inevitably contains some impurities and sediments. So when the booster pump is turned off, the water in the water pipe will slowly flow towards the flushing pipe, causing the impurities in the wastewater to gradually accumulate at the nozzles of the flushing pipe. This can easily cause the nozzles to become clogged, resulting in the need for frequent cleaning of the nozzles.

[0009] In this solution, a water valve is installed on the water pipe connecting the flushing pipe and the booster pump. When it is not necessary to flush the filter cloth of the desludge machine, the booster pump is turned off, and then the water valve is turned off. This can effectively reduce the situation where residual water in the water pipe continues to flow into the flushing pipe, thereby reducing the likelihood of nozzle blockage. This reduces the speed at which the nozzles become blocked, avoids the need for frequent nozzle cleaning, and reduces labor costs.

[0010] Furthermore, it also includes a control component, wherein the water valve is a solenoid valve, and the desliming machine, the booster pump, and the water valve are all electrically connected to the control component; the control component is used to control the automatic opening and closing of the desliming machine, the booster pump, and the water valve.

[0011] The control components in this solution are electrically connected to the desliming machine, the booster pump, and the water valve. By pre-setting the start and stop sequence of the desliming machine, the booster pump, and the water valve, the control components can automatically control the opening and closing of the desliming machine, the booster pump, and the water valve, thereby achieving automatic control and greater automation. This eliminates the need for manual operation and effectively improves work efficiency.

[0012] Furthermore, it also includes an air compressor, which is connected to the desludge dewatering machine via an air pipe, and the air compressor is electrically connected to the control component.

[0013] The air compressor in this solution provides additional pressure to the sludge dewatering machine, driving the filter cloth or filter plate with compressed air to apply higher pressure to the sludge, significantly improving solid-liquid separation efficiency. Similarly, this solution uses control components to automatically control the air compressor's start-up time smoothly, resulting in greater automation.

[0014] Furthermore, a pressure sensor is installed on the air pipe connecting the air compressor and the desludge machine, and the pressure sensor is electrically connected to the control component.

[0015] In this solution, a pressure sensor is installed on the air pipe connecting the air compressor and the desludge dewatering machine. This pressure sensor can detect the pressure generated by the air compressor. When the pressure reaches the specified value, the control component will start the desludge dewatering machine. This ensures that the desludge dewatering machine starts only after the air compressor has reached a certain pressure, thereby guaranteeing the desludge dewatering machine's sludge compression effect.

[0016] Furthermore, a pressure gauge is installed on the air pipe connecting the air compressor and the desludge machine.

[0017] The pressure gauge allows personnel on-site to more intuitively observe the pressure of the desliming machine.

[0018] Furthermore, a U-shaped pipe is connected to the water pipe between the water valve and the flushing pipe.

[0019] In this design, the U-shaped pipe forms a local low-level water storage area. When the booster pump and water valve are both closed, the water flow inertia pushes the residual water into the bottom of the U-shaped pipe for temporary storage, which can then be further flowed to the nozzle.

[0020] Furthermore, a drain pipe is connected to the bottom of the U-shaped tube, and a drain valve is installed on the drain pipe.

[0021] The drain pipe and drain valve in this solution facilitate the regular cleaning of sediment and impurities inside the U-shaped pipe. At the same time, it allows the drain valve to be opened after the pump is stopped to drain the water in the pipe, avoiding static pressure residue that causes water to continuously impact the nozzle. Furthermore, it prevents water from continuing to flow into the nozzle after the pump is stopped, thus avoiding nozzle clogging.

[0022] Furthermore, the water pipe between the U-shaped pipe and the flushing pipe is inclined downwards towards the U-shaped pipe.

[0023] This solution can further utilize gravity to direct the water near the flushing pipe into the U-shaped pipe along the inclined water pipe, further blocking the water flow to the flushing pipe and further reducing nozzle clogging.

[0024] Furthermore, a filter is connected to the water pipe between the water valve and the flushing pipe. The filter is Y-shaped and includes an outlet pipe, an inlet pipe, and a vertical pipe. A filter screen is installed in the outlet pipe of the filter. The inlet pipe and the outlet pipe of the filter are respectively connected to the water pipe between the water valve and the flushing pipe. The vertical pipe is arranged vertically.

[0025] The filter in this solution can filter impurities in the greywater, further preventing nozzle clogging. In addition, the filter in this solution is Y-shaped, so the filtered impurities will settle in the vertical pipe under gravity, enhancing the interception effect.

[0026] Furthermore, a slag discharge cover is detachably connected to the bottom of the vertical pipeline.

[0027] In this design, the slag discharge cover is detachably connected to the bottom of the vertical pipeline, making it easy to open the slag discharge cover to discharge impurities from the vertical pipeline. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0037] Example 1

[0038] like Figures 1-2 As shown, this embodiment 1 provides a desliming machine operating system, including a desliming machine 1, a pressurizing pump 5, and flushing pipes 2. The flushing pipes 2 are equipped with nozzles, and each flushing pipe 2 has multiple nozzles spaced apart. Furthermore, the flushing pipes 2 on the desliming machine 1 can be configured in two or more ways according to actual needs (such as the size of the desliming machine 1), increasing the flushing area by spacing the flushing pipes 2 apart. Multiple flushing pipes 2 are connected to the same main water pipe via branch water pipes, facilitating simultaneous water supply to multiple flushing pipes 2.

[0039] In this embodiment, the outlet end of the booster pump 5 is connected to the flushing pipe 2 via a water pipe, and the inlet end of the booster pump 5 is connected to the water source; a water valve 7 is installed on the water pipe connecting the flushing pipe 2 and the booster pump 5. The water valve 7 is installed on the main water pipe or on each branch water pipe. In this embodiment, the water valve 7 is installed on the main water pipe as an example.

[0040] This embodiment also includes an air compressor 4, which is connected to the desliming machine 1 via an air pipe. Before the desliming machine 1 is run, the air compressor 4 is started so that the pressure provided by the air compressor 4 reaches the pressure value that allows the desliming machine 1 to run normally, and then the desliming machine 1 is started to run.

[0041] By opening the pressure pump 5 and the water valve 7, the pressure pump 5 supplies high-pressure water to the flushing pipe 2, and the high-pressure water is then sprayed out through the nozzle to flush the filter cloth or filter plate on the desludge machine 1 under high pressure.

[0042] When high-pressure rinsing of the filter cloth or filter plate is not required, the water path between the pressure pump 5 and the water valve 7 is cut off by first turning off the pressure pump 5 and then turning off the water valve 7. This reduces the risk of a large amount of water slowly flowing towards the nozzle after the pressure pump 5 is turned off, which could cause impurities in the water to clog the nozzle.

[0043] Example 2

[0044] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, a U-shaped pipe 8 is connected to the water pipe between the water valve 7 and the flushing pipe 2. The connection between the U-shaped pipe 8 and the water pipe can be fixed by welding or by threaded connection. The threaded connection method is used to facilitate the installation and disassembly of the U-shaped pipe 8.

[0045] In this embodiment, a drain pipe 9 is connected to the bottom of the U-shaped tube 8, and a drain valve 10 is installed on the drain pipe 9. By opening the drain valve 10, the impurities that have settled in the U-shaped tube 8 can be discharged periodically to avoid blockage in the U-shaped tube 8.

[0046] In this embodiment, by setting up a U-shaped pipe 8, a local low-level water storage area is formed. When the booster pump 5 is turned off, the water flow inertia pushes the residual water into the bottom of the U-shaped bend for temporary storage. The residual water is then collected at the bottom of the U-shaped bend by gravity. After the pump stops, the water in the pipe is drained quickly by opening the drain valve 10, thus avoiding static pressure residue that causes the water flow to continuously impact the nozzle.

[0047] Example 3

[0048] like Figure 3 As shown, the difference between this embodiment and embodiment 2 is that in this embodiment, the water pipe between the U-shaped pipe 8 and the flushing pipe 2 is inclined downwards towards the U-shaped pipe 8. That is, there is an inclined pipe 11 connecting the flushing pipe 2 and the U-shaped pipe 8. The inclined pipe 11 is inclined downwards from the flushing pipe 2 towards the U-shaped pipe 8, so that the water path between the flushing pipe 2 and the U-shaped pipe 8 has a slope. In this way, when the pressure pump 5 is turned off, the water remaining in the flushing pipe 2 and the water in the pipe connected to the flushing pipe 2 can be introduced into the U-shaped pipe 8, reducing the residual water flow and further alleviating the situation of impurities clogging the nozzle.

[0049] Example 4

[0050] like Figure 4 As shown, the difference between this embodiment and the above embodiment is that: in this embodiment, a filter 12 is connected to the water pipe between the water valve 7 and the flushing pipe 2. The filter 12 in this embodiment is Y-shaped and includes an outlet pipe, an inlet pipe and a vertical pipe. The outlet pipe, inlet pipe and vertical pipe are interconnected and integrally formed, forming a Y-shaped structure. A filter screen 13 is installed in the outlet pipe of the filter 12. In this embodiment, the filter screen 13 is installed on the side of the outlet pipe of the filter 12 close to the vertical pipe, which facilitates the entry of filtered impurities into the vertical pipe.

[0051] In this embodiment, the inlet and outlet pipes of the filter 12 are connected to the water pipe between the water valve 7 and the flushing pipe 2, respectively. The vertical pipes are arranged vertically, which facilitates the use of gravity to guide the filtered impurities into the vertical pipes for collection and reduces the impact on the water flow. In this embodiment, the inlet and outlet pipes of the filter 12 are connected to the water pipe by welding, threading, or other means, and no specific limitation is made here.

[0052] In this embodiment, a slag discharge cover 14 is detachably connected to the bottom of the vertical pipe. Specifically, in this embodiment, the slag discharge cover 14 is threadedly connected to the bottom of the vertical pipe. When it is necessary to discharge impurities in the vertical pipe, the impurities can be discharged by opening the slag discharge cover 14.

[0053] The filter 12 in this embodiment can filter greywater, reducing impurities carried in the greywater, thereby further alleviating nozzle clogging.

[0054] Example 5

[0055] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that: the desliming machine operating system in this embodiment also includes a control component 3, the water valve 7 in this embodiment is a solenoid valve, and the desliming machine 1, the booster pump 5, the air compressor 4 and the water valve 7 are all electrically connected to the control component 3; the control component 3 is used to control the automatic opening and closing of the desliming machine 1, the booster pump 5, the water valve 7 and the air compressor 4.

[0056] In this embodiment, a pressure sensor 6 is installed on the air pipe connecting the air compressor 4 and the desliming machine 1. The pressure sensor 6 is electrically connected to the control component 3.

[0057] In this embodiment, the control component 3 includes a PLC controller, an HMI interface, and relays. The PLC controller controls the start and stop of the air compressor 4 and the pressurizing pump 5. Based on the pressure value detected in real time by the pressure sensor 6, the PLC controller automatically controls the start of the desludge dewatering machine 1. Specifically, the PLC controller starts the air compressor 4 by sending a command to generate compressed air to supply the filter belt tensioning cylinder of the desludge dewatering machine 1. The pressure sensor 6 detects the system pressure. When the pressure sensor 6 detects that the system pressure meets the standard, it triggers the desludge dewatering machine 1 to start and begin compressing and filtering the sludge.

[0058] The PLC controller is pre-set to control the opening time of the pressurizing pump 5 and the water valve 7, such as opening for 5 minutes every 20 minutes, so that the flushing pipe 2 can flush the filter cloth and prevent clogging. The control circuit of the water valve 7 is linked to the power supply of the pressurizing pump 5. The PLC controller implements the trigger logic of "the water valve 7 closes after the pump is powered off", ensuring that the water valve 7 receives the closing command after the pressurizing pump 5 stops.

[0059] In practice, the closing priority of water valve 7 can be set on the PLC controller, forcing the pressure pump 5 to stop before closing water valve 7. A delayed closing function can also be added by adding a time relay, such as delaying the closing of water valve 7 by 0.5 seconds after the pressure pump 5 stops. PLC controller control of the start and stop of various devices is existing technology and will not be elaborated upon further here.

[0060] In this embodiment, each device is connected to the automatic control system, eliminating the need for manual start-up and shutdown, resulting in higher efficiency and greater automation.

[0061] Example 6

[0062] The difference between this embodiment and Embodiment 1 is that, in this embodiment, a pressure gauge is also installed on the air pipe connecting the air compressor 4 and the desliming machine 1. The pressure gauge in this embodiment allows personnel to visually observe the operating pressure status of the desliming machine 1 on-site.

[0063] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. 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 scope of this application. Therefore, this application 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.
