Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and more specifically, to a sludge discharge control device. Background Technology

[0002] Most water treatment equipment uses sedimentation to trap pollutants and form sludge before being discharged. Therefore, such equipment requires sludge removal at regular intervals. The timing of sludge removal significantly impacts the equipment's treatment efficiency. Excessive sludge removal can clog internal passages, affecting water output and potentially damaging the equipment's internal structure. Conversely, excessively frequent sludge removal leads to a larger volume of discharged sludge, wasting water resources and negatively impacting subsequent dewatering processes. Therefore, precisely controlling the sludge removal cycle is essential for safe production and green manufacturing, and is also a trend in intelligent operation and maintenance.

[0003] There are two main methods for controlling sludge discharge: The first method is time-based control, which involves selecting a fixed sludge discharge cycle and discharging sludge at regular intervals. This method lacks any monitoring or verification mechanisms, relying entirely on experience, and is a crude control approach. It has the following drawbacks:

[0004] 1. The sludge removal cycle is selected manually and relies on experience to set, which is quite unpredictable;

[0005] 2. The quality of incoming water often fluctuates, and the amount of sludge produced will change accordingly. Fixed-cycle sludge discharge will lead to uneven sludge discharge, which will affect the equipment performance and is not conducive to the operation of the downstream sludge dewatering section.

[0006] Another method is to use a sludge level measuring instrument to measure the sludge level and use the measurement results to guide the setting of the sludge discharge cycle, aiming to achieve automatic adjustment based on operating conditions and discharge sludge on demand. However, this method has the following disadvantages:

[0007] 1. The detection instruments are easily damaged. Most mud level measuring instruments need to be immersed in water, and not clean water, but sewage containing mud. The operating conditions are harsh, and probe clogging or equipment failure is likely to occur. The cleaning and maintenance work is very complicated and tedious.

[0008] 2. Insufficient accuracy: Sludge level measuring instruments are usually measured at points, but sludge distribution is usually not horizontal. Therefore, a single point does not represent the total amount of sludge in the entire water treatment equipment or device. Even with multiple point measurements, this problem still exists.

[0009] 3. Installation is limited. Many water treatment equipment and devices have internal mechanical devices or flow channels, which are limited by space or travel, making it impossible to install mud level measuring instruments. Utility Model Content

[0010] In view of the above problems, the purpose of this utility model is to provide a sludge discharge control device to solve the problems in the prior art, such as the limited installation of sludge level measuring instruments in water equipment, their susceptibility to damage by mud and water, and insufficient measurement accuracy, which leads to inaccurate judgment of sludge discharge timing.

[0011] The sludge discharge control device provided by this utility model includes a weight measuring device, a data processing device, and a sludge discharge prompting device; wherein...

[0012] The weight measuring device is located at the bottom of the main body of the water treatment equipment;

[0013] The data processing device includes a signal transmission mechanism connected to the weight measuring device and a main control device connected to the signal transmission mechanism;

[0014] The main control device includes a data processing module and a control module; wherein, the data processing module is used to calculate the real-time weight of sludge inside the water treatment equipment body based on the real-time weight data of the water treatment equipment body measured by the weight measuring device transmitted by the signal transmission mechanism, and the control module is used to determine whether to generate a sludge discharge signal based on the real-time sludge weight and the preset sludge weight.

[0015] The sludge discharge indicator is connected to the control module.

[0016] Furthermore, in a preferred configuration, the weight measuring device includes an equipment support base and a weight measuring element disposed on top of the equipment support base; the main body of the water treatment equipment is disposed on top of the weight measuring element.

[0017] Furthermore, in a preferred configuration, the equipment support foundation comprises a concrete foundation and an embedded part disposed on top of the concrete foundation; the weight measuring component is disposed on top of the embedded part.

[0018] Furthermore, a preferred configuration is that the weight measuring device is a weighbridge or an industrial platform scale.

[0019] Furthermore, in a preferred configuration, the signal transmission mechanism is a transmitter; the data processing module includes a signal data conversion submodule connected to the transmitter and a data calculation submodule connected to the signal data conversion submodule.

[0020] Furthermore, a preferred configuration is that the main control device is a PLC controller.

[0021] Furthermore, in a preferred configuration, both the main control device and the sludge discharge indicator are located on the same control box; the main control device is located inside the control box; and the sludge discharge indicator is located on the outside of the control box door.

[0022] Furthermore, in a preferred configuration, the data processing device further includes a touchscreen connected to the main control device; the touchscreen is connected to both the parameter setting interface and the data display interface of the main control device; and the touchscreen is located on the outside of the control box door.

[0023] Furthermore, in a preferred configuration, the sludge discharge indicator is an indicator light.

[0024] Furthermore, in a preferred configuration, the control module is connected to the control system of the sludge discharge valve at the bottom of the main body of the water treatment equipment.

[0025] As can be seen from the above technical solution, the sludge discharge control device provided by this utility model measures the weight of the main body of the water treatment equipment in real time by setting a weight measuring device at the bottom of the main body of the water treatment equipment. The signal transmission mechanism transmits the real-time weight data of the main body of the water treatment equipment to the main control device. The data processing module of the main control device calculates the real-time weight of the sludge inside the main body of the water treatment equipment based on the difference between the real-time weight data of the main body of the water treatment equipment and the initial weight data when the main body of the water treatment equipment is full of water and has no sludge. Then, the control module determines whether to generate a sludge discharge signal based on the relationship between the real-time weight of the sludge and the preset sludge weight. If the real-time weight of the sludge is greater than or equal to the preset sludge weight, the control module generates a sludge discharge signal and sends it to the sludge discharge prompt device to remind the staff to discharge the sludge from the main body of the water treatment equipment. This utility model can accurately determine the best time for sludge discharge based on the changes in the amount of sludge caused by changes in the inflow water volume and water quality, thus avoiding the waste of water resources. The weight measuring device is set on the outside of the main body of the water treatment equipment, which does not affect the internal structure of the water treatment equipment and will not be damaged by long-term immersion in muddy water. The device has a long service life and reduces maintenance costs. Attached Figure Description

[0034] In response to the aforementioned problems in the prior art, such as the limited installation of mud level measuring instruments in water equipment, their susceptibility to damage by mud and water, and insufficient measurement accuracy leading to inaccurate judgment of mud discharge timing, a mud discharge control device is proposed.

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] To illustrate the sludge discharge control device provided by this utility model Figure 1 The structure of the sludge discharge control device according to an embodiment of the present invention is shown; Figure 2 The structure of the equipment support foundation according to an embodiment of the present invention is shown; Figure 3 The principle of the sludge discharge control device according to an embodiment of the present invention is shown; Figure 4 The external structure of the control box according to an embodiment of the present invention is shown; Figure 5 The internal structure of the control box according to an embodiment of the present invention is shown.

[0037] like Figures 1 to 5 As shown in the figure, the sludge discharge control device provided by this utility model includes a weight measuring device 1, a data processing device 2, and a sludge discharge prompting device 3. The weight measuring device 1 is located at the bottom of the water treatment equipment body 4. The data processing device 2 includes a signal transmission mechanism 21 connected to the weight measuring device 1 and a main control device 22 connected to the signal transmission mechanism 21. The main control device 22 includes a data processing module and a control module. The data processing module calculates the real-time weight of the sludge inside the water treatment equipment body 4 based on the real-time weight data of the water treatment equipment body 4 measured by the weight measuring device 1 transmitted by the signal transmission mechanism 21. The control module determines whether to generate a sludge discharge signal based on the real-time sludge weight and a preset sludge weight. The sludge discharge prompting device 3 is connected to the control module.

[0038] Specifically, the weight measuring device 1 and the signal transmission mechanism 21 can be connected via a data cable or a signal connection; the signal transmission mechanism 21 and the main control device 22 can be connected via a data cable or a signal connection; this utility model does not impose any particular limitations on this.

[0039] By installing a weight measuring device 1 at the bottom of the main body 4 of the water treatment equipment, the weight of the main body 4 of the water treatment equipment is measured in real time. The signal transmission mechanism 21 transmits the real-time weight data of the main body 4 of the water treatment equipment to the main control device 22. The data processing module of the main control device 22 calculates the real-time weight of sludge inside the main body 4 of the water treatment equipment based on the difference between the real-time weight data of the main body 4 of the water treatment equipment and the initial weight data when the main body 4 of the water treatment equipment is full of water and has no sludge. Then, the control module determines whether to generate a sludge discharge signal based on the relationship between the real-time weight of the sludge and the preset sludge weight. If the real-time weight of the sludge is greater than or equal to the preset sludge weight, the control module generates a sludge discharge signal and sends it to the sludge discharge prompt device 3 to remind the staff to discharge sludge from the main body 4 of the water treatment equipment. This utility model can accurately determine the best time for sludge discharge based on the changes in the amount of sludge caused by changes in the inflow water volume and water quality, thus avoiding the waste of water resources. The weight measuring device is set on the outside of the main body of the water treatment equipment, which does not affect the internal structure of the water treatment equipment and will not be damaged by long-term immersion in muddy water. The device has a long service life and reduces maintenance costs.

[0040] The working principle of this invention is as follows: The amount of sludge inside the water treatment equipment is calculated by utilizing the change in its operating weight. The operating weight of the water treatment equipment consists of two parts: the weight of the main body 4 of the water treatment equipment + the weight of the internal medium. The weight of the main body 4 is considered a fixed value. The weight of the medium includes the weight of water and the weight of sludge. The total volume inside the main body 4 remains constant, but the specific gravities of water and sludge are different. Therefore, as the amount of sludge increases during operation, the weight of the medium will change due to the change in the ratio of water to sludge, and this weight change is directly proportional to the amount of sludge. Therefore, by measuring the weight, the change in weight can be converted into a change in the amount of sludge, thereby accurately controlling the sludge discharge time. A weight measuring device 1 is installed below the main body 4 of the water treatment equipment to detect its operating weight. The initial value is a full water, sludge-free state, marked as W1. The real-time operating weight is W2. The difference between W2 and W1 is the amount of sludge retained inside the equipment. The weight measuring device 1 can detect the weight data of the equipment in real time or periodically. The data processing device 2 converts the weight data into sludge volume. By setting a preset sludge weight value, when the preset value is reached, the sludge discharge prompt device 3 will provide a prompt or upload it to the control room for display. When the sludge volume, i.e. the weight, reaches a certain value, the equipment will be notified to perform sludge discharge and other operations.

[0041] As a preferred embodiment of the present invention, the weight measuring device 1 includes an equipment support base 11 and a weight measuring component 12 disposed on top of the equipment support base 11; the water treatment equipment body 4 is disposed on top of the weight measuring component 12.

[0042] The weight measuring component 12 is mounted on top of the equipment support base 11 for easy installation and cable connection. The equipment support base 11 serves to support the weight measuring component 12 and the main body 4 of the water treatment equipment.

[0043] As a preferred embodiment of the present invention, the equipment support foundation 11 includes a concrete foundation 111 and an embedded part 112 disposed on the top of the concrete foundation 111; the weight measuring part 12 is disposed on the top of the embedded part 112.

[0044] The number of embedded parts 112 is preferably, but not limited to, four, used for horizontal support of the weight measuring component 12, and can be determined according to the specific shape and volume of the weight measuring component 12. During the pouring of the concrete foundation 111, the foundation strength should be sufficient to support the operating weight of the water treatment equipment and the weight of the weight measuring component 12. At the same time, the levelness, position, and other dimensions of the embedded parts 12 on the top surface of the concrete foundation must also be guaranteed.

[0047] As a preferred embodiment of this utility model, the signal transmission mechanism 21 is a transmitter; the data processing module includes a signal data conversion submodule connected to the transmitter and a data calculation submodule connected to the signal data conversion submodule.

[0048] The transmitter is used to convert the measurement data in the weight measuring element 12 into a 4-20mA signal, and then transmit it to the signal data conversion submodule. The signal data conversion submodule then converts the signal back into the measured weight data, and then transmits it to the data calculation submodule to calculate the weight of sludge retained in the main body 4 of the water treatment equipment.

[0049] As a preferred embodiment of this utility model, the main control device 22 is a PLC controller.

[0052] By setting up control box 5, the main control device 22 and the sludge discharge indicator device 3 are integrated together, which facilitates operation.

[0054] The parameter setting interface of the main control device 22 can be used to set data parameters, such as the initial weight data and preset sludge weight when the main body 4 of the water treatment equipment is full of water and free of sludge. These settings are input via the touchscreen 23. The data display interface is connected to the touchscreen 23 and can display the sludge volume in real time for easy viewing by staff. The preset sludge weight can be set with one or more sludge discharge design values, or selected based on operational experience. When the real-time sludge volume (i.e., weight) reaches the preset sludge weight, a cascading sludge discharge or audible and visual alarm can be triggered to alert the operator for manual handling.

[0055] As a preferred embodiment of this utility model, the mud discharge indicator 3 is an indicator light.

[0056] It should be noted that the mud discharge indicator device 3 is preferably, but not limited to, an indicator light, and may also be an audible and visual alarm, etc.

[0058] Automatic sludge discharge can be achieved by connecting the control module to the control system 6 of the sludge discharge valve at the bottom of the main body 4 of the water treatment equipment.
