Abstract
Description

[0002] Water is the source of life. The final process of water treatment in water plants and sewage treatment plants involves sludge dewatering treatment technology. In this process, the sludge buffer bucket is an important sludge buffer device. This equipment can store 60%~90% of the sludge and then transport the sludge out through the sludge discharge pump. In this process, the sludge buffer bucket is used to ensure the buffering and temporary storage of the sludge.
[0003] At present, most of the sludge buffering devices on the market use a combination of high and low resistance rotary level meters and a disintegrator. Since the sludge water content of the sludge from the sludge treatment equipment is high and the sludge has high adhesion, some of the sludge will adhere to the disintegrator and the side wall of the buffer bucket during operation, resulting in the phenomenon of sludge accumulation at the upper end and empty sludge at the lower end of the equipment, as well as material level detection errors, which can easily burn the sludge pump and cause large economic losses. At the same time, the manufacturing cost of this solution is high, and the later maintenance is difficult, which brings great difficulty to the operation and maintenance personnel.

[0031] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.
[0032] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.
[0033] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0034] See also Figure 1 and Figure 2 The embodiment of the present application discloses a sludge buffer bucket with liquid level detection, including: a box body 10, an electrode liquid level meter 20 and a rotary paddle level meter 30. The box body 10 is also the sludge buffer bucket, which is used to temporarily store sludge. The electrode liquid level meter 20 and the rotary paddle level meter 30 are both arranged above the box body 10.
[0035] See also Figure 3 One end of the electrode liquid level meter 20 is provided with a first material level electrode rod 21 and a second material level electrode rod 22 located in the box body 10. The first material level electrode rod 21 and the second material level electrode rod 22 are electrode rods, and the lengths of the two are different, and the corresponding detection material level heights are different. During the monitoring process, once the first material level electrode rod 21 and / or the second material level electrode rod 22 contacts the liquid, an electric current will be generated and a signal will be detected to determine the material level, that is, the height position of the sludge.
[0036] In this description, see Figure 3 The first material level electrode rod 21 is higher than the second material level electrode rod 22. When the first material level electrode rod 21 detects a signal but the second material level electrode rod 22 does not detect a signal (that is, there is mud accumulation at the upper end of the corresponding box body 10 and no mud at the lower end), a judgment can be made based on the two signals to control the operation of the mud pump so that the mud pump stops running to avoid burning the mud pump.
[0037] See also Figure 1 and Figure 3The paddle-rotor level meter 30 and the electrode-type liquid level meter 20 are fixed on the same side of the box body 10, that is, above the box body 10. The height of the paddle-rotor level meter 30 in the box body 10 is slightly higher than the first material level electrode rod 21, and is used to detect a higher material level. When the material level signal is detected, the centrifuge can be controlled to discharge mud to prevent sludge overflow.
[0038] The working principle of the rotary resistance material level meter 30 is to use a permanent magnet motor to drive the blade to rotate. When the material to be detected rises to the blade position, the rotation of the blade is blocked, and the resistance is transmitted to the detection device. The detection device then outputs a switch signal, cuts off the power supply to stop the blade from rotating, and sends a signal to control the centrifuge to discharge mud. Here, the rotary resistance material level meter 30 is an existing related technology and will not be described in detail here.
[0039] See also Figure 2 and Figure 4 A sludge buffer bucket with liquid level detection also includes a mounting frame 40, which is located in the box body 10, and one end of the mounting frame 40 is fixed to the side wall of the box body 10, and the other end abuts and is perpendicular to the electrode type liquid level meter 20.
[0040] Among them, threaded holes (not marked in the figure) are provided on the side of the box body 10, and screws are connected to the mounting frame 40 through the threaded holes on the outside of the box body. The mounting frame 40 abuts against the electrode level meter 20, that is, abuts against the first material level electrode rod 21 and the second material level electrode rod 22 respectively, and plays a supporting role for both. In addition, the installation position of the electrode level meter 20 can be adjusted based on the length of the mounting frame 40, that is, the distance between the first material level electrode rod 21 and the second material level electrode rod 22 and the side wall of the box body 10 is adjusted, so as to reduce the risk of sludge bridging and adhering to the side wall of the box body 10 based on the electrode level meter 20.
[0041] Specifically, the first material level electrode rod 21 and the second material level electrode rod 22 are parallel to each other, and two support frames are provided, which are respectively perpendicular to the first material level electrode rod 21 and the second material level electrode rod 22. This structure can ensure the stability of the first material level electrode rod 21 and the second material level electrode rod 22 in the box body 10, so as to further ensure the accuracy of material level detection.
[0042] See also Figure 2 An upper cover 11 is disposed above the box body 10 , and a first material level electrode rod 21 and a second material level electrode rod 22 are fixed on the upper cover 11 .
[0043] Among them, the upper cover 11 and the box body 10 are detachably connected, and multiple screw holes are set on the upper cover 11 and the box body 10, which can be connected by screws to facilitate the assembly, maintenance and disassembly of the sludge buffer, and to facilitate the installation and fixation of the electrode level meter 20 and the rotary level meter 30.
[0044] See also Figure 1 A feed port 111 is provided on the upper cover 11, and a flexible connection such as a hose is connected to the front end to feed the sludge into the box 10. In this embodiment, the shape of the feed port 111 can be rectangular, circular, etc., as long as the same effect can be achieved.
[0045] See also Figure 3 In order to facilitate the operator to observe the state of the sludge in the box body 10 in real time, an observation port 12 is also provided on the side of the box body 10 .
[0046] A light-transmitting material is provided on the observation port 12, and the light-transmitting material is, for example, an acrylic plate with good light transmittance and hardness. In this embodiment, the shape of the feed port 111 can be rectangular, circular, etc., as long as the same effect can be achieved.
[0047] In summary, the embodiment of the present application discloses a sludge buffer capable of liquid level detection, which can transmit signals of different material levels in real time based on the difference in length between the first material level electrode rod 21 and the second material level electrode rod 22, and control the start and stop of the mud pump based on the signals, thereby ensuring the safe and stable operation of the mud pump; and a rotary paddle level meter 30 is provided at one end of the box body 10, and is higher than the first material level electrode rod 21, for detecting a higher material level, so that when the material level signal is detected, the centrifuge is controlled to discharge mud, so as to prevent sludge overflow. In this way, the embodiment of the present application can ensure the safe and stable operation of the mud pump through the combination of the electrode liquid level meter 20 and the rotary paddle level meter 30, and at the same time can reduce costs and simplify the structure, facilitating subsequent maintenance.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
