Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a mechanical opening adjustment device for a sludge suction machine. Background Technology

[0002] Traditional sludge suction machines have a fixed opening adjustment, making it impossible for operators to flexibly and accurately control the opening of the suction pipe according to actual working conditions. Furthermore, when adjusted to the desired opening position, the position is typically maintained by friction between components or the self-locking property of the threads, failing to achieve reliable fixation. During equipment operation, vibration, fluid impact, or changes in pipeline pressure can easily cause the adjusted opening to deviate, leading to unstable sludge suction efficiency, increased energy consumption, and the need for frequent adjustments by operators. This not only increases the workload but also makes it difficult to ensure the accuracy and continuity of process control. Utility Model Content

[0003] The purpose of this invention is to provide a mechanical opening adjustment device for a sludge suction machine that is adjustable and can be stably locked.

[0004] To achieve the above-mentioned objectives, the mechanical opening adjustment device for a sludge suction machine adopts the following technical solution:

[0005] A mechanical opening adjustment device for a sludge suction machine includes a drive mechanism, a rotating tube, and a suction tube. The suction tube is vertically arranged, with its lower end extending into a sludge collection trough and having a suction port for sucking sludge from the trough. The upper end of the suction tube extends into a sludge discharge trough and is movably fitted inside the rotating tube. The rotating tube has a sludge discharge port, and the suction tube has a flow port. The rotating tube is rotated to adjust the flow area between the sludge discharge port and the flow port. The drive mechanism includes a drive rod, a drive handwheel, and a support base. The drive rod is rotatably mounted on the support base via a bearing unit. The lower end of the drive rod is connected to the rotating tube, and the upper end of the drive rod is connected to the drive handwheel. The bearing unit has a telescopic locking component. A limiting plate is located above the telescopic locking component on the drive rod. The limiting plate has multiple locking holes for easy insertion of the telescopic locking component, distributed along a portion of the circumference of the limiting plate. A scale plate is located on the upper surface of the limiting plate, with through holes corresponding to the locking holes. The scale plate has graduation marks at the through holes.

[0006] Preferably, the bearing unit includes a bearing housing, a bearing, and a bearing cap. The bearing housing is located at the upper end of the support base, and the telescopic locking component is located on the bearing cap. This structural layout is reasonable, modularly integrating load-bearing rotation and locking functions, ensuring the stability and smoothness of the drive rod rotation, while providing a stable installation foundation for the telescopic locking component.

[0007] Preferably, the telescopic locking element is a spring pin. This structure utilizes a spring to provide automatic reset force, making operation simple and quick. Reliable locking is achieved by inserting it into the lock hole, and unlocking and adjustment are achieved by pulling it out. It has the advantages of simple structure, low cost, and reliable operation.

[0008] Preferably, five through holes are provided, and each through hole has a scale mark, including a fully open mark, a three-quarters open mark, a half open mark, a quarter open mark, and a closed mark. By presetting the working positions, the precise opening requirements of most working conditions can be met, and the operation and identification are more intuitive and convenient, reducing the possibility of misoperation.

[0009] Preferably, the scale plate is a metal plate, and the scale plate is set in an arc shape. The use of a metal plate ensures the wear resistance of the scale markings and the clarity of the markings over long-term use; the arc shape design matches the circumferential movement trajectory of the limiting disc, making it easy to observe and read, and improving the user experience.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through the cooperation of a drive handwheel, drive rod, and rotating tube, can precisely control the overlap area between the flow port on the suction pipe and the discharge port on the rotating tube, thereby achieving adjustment of the opening degree. More importantly, by setting a locking mechanism consisting of a telescopic locking element and a limiting disc with multiple locking holes, the drive rod and rotating tube can be securely locked at any preset opening degree position, effectively solving the problem of opening degree deviation caused by vibration or impact in traditional methods, and ensuring the stability and reliability of equipment operation.

[0012] 2. Operators can easily adjust and fix the opening by simply rotating and locking the pins; the process is intuitive, simple, and labor-saving. The scale plate with through holes on the upper surface of the limit plate provides a clear, visual mark for each lock hole position, making opening control more precise and intuitive. This greatly reduces the difficulty of operation and reliance on operator experience, and improves adjustment efficiency.

[0013] 3. Because the opening can be precisely controlled and reliably maintained, the sludge suction machine can always operate under optimal conditions, avoiding low suction efficiency or energy waste caused by improper opening, thereby significantly improving the sludge extraction efficiency and reducing the overall energy consumption of the system.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] like Figure 1-5As shown, a mechanical opening adjustment device for a sludge suction machine includes a drive mechanism, a rotating tube 11, and a suction pipe 2. The suction pipe 2 is arranged vertically, with its lower end extending into a sludge collection trough 1 and having a suction port 201 for sucking sludge from the sludge collection trough 1. The upper end of the suction pipe 2 extends into a sludge discharge trough 3 and is movably fitted inside the rotating tube 11. The rotating tube 11 has a sludge discharge port 11a, and the suction pipe 2 has a flow port 202. The rotating tube 11 is rotated to adjust the flow area between the sludge discharge port 11a and the flow port 202. The drive mechanism includes a drive rod 4, a drive handwheel 5, and a support base 6. The drive rod 4 is rotatably mounted on the support base 6 via a bearing unit. The lower end of the drive rod 4 is connected to the rotating tube 11, and the upper end of the drive rod 4 is connected to the drive handwheel 5. The bearing unit has a telescopic locking element 12 and includes a bearing seat 10, a bearing 9, and a bearing cap 8. The bearing seat 10 is located at the upper end of the support seat 6, and the telescopic locking member 12 is located on the bearing cover 8. The telescopic locking member 12 is a spring pin, which can be directly purchased from the market. The drive rod 4 is located above the telescopic locking member 12 and is provided with a limiting plate 7. The limiting plate 7 is provided with multiple locking holes 701 for easy insertion of the telescopic locking member 12. The multiple locking holes 701 are distributed in a partial circumferential direction of the limiting plate 7. The upper surface of the limiting plate 7 is provided with a scale plate 13. The scale plate 13 is a metal plate and is set in an arc shape. The scale plate 13 is provided with through holes 14 corresponding to the locking holes 701. The scale plate 13 is provided with scale marks 15 at the through holes 14. There are five through holes 14, and each through hole 14 is provided with a scale mark 15. The scale marks 15 include a fully open mark, a three-quarters open mark, a half open mark, a quarter open mark, and a closed mark.

[0022] The specific working process and principle of this utility model are as follows: The operator drives the drive rod 4 to rotate by rotating the drive handwheel 5, and the rotating tube 11 connected to the lower end of the drive rod 4 rotates synchronously. Since the sludge suction pipe 2 is fixed, the rotation of the rotating tube 11 changes the relative position and overlap area between the sludge discharge port 11a on its side wall and the flow port 202 on the side wall of the sludge suction pipe 2, thereby adjusting the sludge flow cross-sectional area, that is, adjusting the opening. When the required opening is reached, the limiting plate 7 rotates to the corresponding angle with the drive rod 4. The operator inserts the telescopic locking piece 12 on the bearing unit into the corresponding locking hole 701 on the limiting plate 7, thereby connecting the drive rod 4 and the rotating tube. 11. Reliable locking effectively prevents opening deviation caused by equipment vibration or fluid impact; at the same time, the arc-shaped scale plate 13 on the upper surface of the limit plate 7 is aligned with the lock hole 701 through its through hole 14. The operator can intuitively and accurately read and set the current opening by observing the scale marks 15 such as "fully open" and "half open" at the through hole 14; when fully open, the sludge discharge port 11a and the flow port 202 are completely connected; when closed, the sludge discharge port 11a and the flow port 202 are completely offset and not connected; when half open, one-quarter open, or three-quarters open, the sludge discharge port 11a and the flow port 202 partially overlap; ultimately, the opening of the sludge suction machine can be stably, accurately, and conveniently adjusted and controlled.
