Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an adjustable grid assembly for wastewater treatment. Background Technology

[0002] Wastewater treatment is an important part of modern environmental protection and resource recycling. Wastewater treatment grids, as key pretreatment equipment in the wastewater treatment process, mainly function to intercept and remove larger floating objects, suspended solids and other solid debris carried in the wastewater, so as to prevent these debris from entering subsequent treatment units, causing equipment blockage, damage and affecting the efficiency and quality of wastewater treatment.

[0003] Existing wastewater treatment grids typically consist of a set of parallel metal or plastic bars, fixedly installed in wastewater treatment channels or collection wells at certain intervals. Depending on the application scenario and treatment requirements, the material, shape, and spacing of the bars vary. These grids have played a certain role in the long-term wastewater treatment process, providing effective protection for subsequent wastewater treatment processes.

[0004] However, with the continuous expansion of sewage treatment scale and the increasing complexity of water quality, existing sewage treatment grids have gradually revealed some technical problems in actual operation. Among them, a more prominent problem is that debris is easily stuck in the gaps between the grid bars, making it difficult to clean quickly. Since the gaps between the grid bars are fixed, when the sewage contains irregularly shaped or nearly sized debris, these debris can easily become embedded or stuck in the gaps. Traditional cleaning methods often require stopping the machine and manually cleaning with tools, or using complex mechanical devices for auxiliary cleaning. This is not only time-consuming and labor-intensive, but may also damage the grid bars themselves during the cleaning process, reducing the service life and interception efficiency of the grid, and increasing the cost and maintenance difficulty of sewage treatment. Utility Model Content

The adjusting roller is positioned above the upper port of the grid groove, and its surface has a plurality of guide grooves continuously distributed on its surface with a gradually changing arc. Each drive rod has an upper end connected to a guide groove and a lower end connected to a longitudinal grid bar. The drive member drives the adjusting roller to rotate, thereby driving the drive rod connected to each guide groove to move laterally, thus causing each longitudinal grid bar to move laterally and changing the distance between adjacent longitudinal grid bars.

[0006] Furthermore, the adjustment device also includes a sliding frame assembly, which includes two mounting seats, multiple sliding frames, and sliding rods. The two mounting seats are symmetrically arranged on the upper end of the grid member, the sliding rods are connected between the two mounting seats, the sliding frames are slidably disposed outside the sliding rods, and the sliding frames are connected to the lower end of the drive rod.

[0007] Furthermore, the driving component includes a motor, two drive pulleys, and a drive belt. The drive belt is tensioned on the two drive pulleys. One drive pulley is connected to the output shaft of the motor, and the other drive pulley is connected to the axis of the adjusting roller. The drive pulley is used to change the output transmission position to facilitate the setting of the motor.

[0008] Furthermore, a screw frame is provided at the lower end of the sliding frame, and the longitudinal grid bar is connected to the screw frame by bolts screwed to its upper end.

[0009] Furthermore, the grid component includes a grid frame, horizontal grid bars, and vertical grid bars, with the vertical grid bars slidably connected to the horizontal grid bars.

[0010] Furthermore, the transverse grid bar includes front and rear parts, and the two parts are respectively flush with the front and rear surfaces of the grid member. A sliding gap is reserved between the two parts of the transverse grid bar for the longitudinal grid bar to slide and connect.

[0014] Furthermore, a mounting plate is provided on one of the bearing housings, and the motor is mounted on the mounting plate.

[0015] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: Through the spiral-shaped, gradually changing arc grid groove design on the surface of the adjusting roller, combined with the synergistic effect of the sliding frame assembly and the driving component, stepless and precise adjustment of the longitudinal grid bar spacing is achieved, which can flexibly adapt to the interception requirements of different sewage impurity sizes; the symmetrically distributed sliding frame assembly and transmission pulley structure ensures the uniformity of power transmission and the stability of the adjustment process; at the same time, the optimized transmission layout of the motor and adjusting roller optimizes the installation space and facilitates maintenance; the sliding connection structure of the longitudinal grid bars and grid grooves, and the transverse grid bars, as well as the bolt-type detachable connection design, not only ensure the guiding accuracy and operational reliability of the grid bar movement, but also simplify the disassembly and maintenance process, effectively improving sewage treatment efficiency and equipment service life.

The content protected by this utility model does not involve any improvement to the internal structure and method.

[0025] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please refer to Figures 1 to 3 An embodiment of this utility model provides an adjustable grid assembly for sewage treatment, including a grid component 100 and an adjustment device 200.

[0027] In this embodiment, the grid member 100 includes a grid frame 11, a horizontal grid bar 12 and a vertical grid bar 14. The vertical grid bar 14 is slidably connected to the horizontal grid bar 12. The horizontal grid bar 12 includes front and rear parts, and the two parts are respectively flush with the front and rear surfaces of the grid member 100. A sliding gap is reserved between the two parts of the horizontal grid bar 12 for the vertical grid bar 14 to slide.

[0028] This structural design ensures stable sliding of the longitudinal grid bars 14 within the grid component 100. Meanwhile, the split design of the transverse grid bars 12 and the reserved sliding gap make the sliding of the longitudinal grid bars 14 smoother, improving the reliability and service life of the entire grid assembly.

[0029] In this embodiment, a grid groove 15 is provided inside the grid frame 11, and the longitudinal grid strip 14 is slidably connected to the grid groove 15. The grid groove 15 in the grid frame 11 is connected to the opening of the grid frame 11 through an opening 13. The longitudinal grid strip 14 extends into the opening 13, so that the longitudinal grid strip 14 can move laterally inside the grid member 100, thereby changing the spacing between the grid strips and providing a basis for adjusting the grid gap.

[0030] Furthermore, the adjusting device 200 is used to adjust the grid gap, and includes an adjusting roller 23, a drive rod 28 and a drive member. The drive member is connected to the adjusting roller 23, which is located above the upper port of the grid groove 15. The surface of the adjusting roller 23 is provided with a plurality of guide grooves 24, which are continuously distributed on the surface of the adjusting roller 23 with a gradually changing arc.

[0031] It should be further explained that the guide grooves 24 are spirally distributed on the surface of the pitch roller 23, and the inclination of adjacent guide grooves 24 is different. Therefore, the sliding distance of adjacent sliding frame groups connected to the guide grooves 24 is different, thus the spacing between adjacent longitudinal grid bars 14 can be changed.

[0032] Specifically, when the drive unit is started, the drive unit drives the adjusting roller 23 to rotate, which causes the guide groove 24 outside the adjusting roller 23 to be pulled. Since the drive rod 28 is connected to the guide groove 24, the gradual arc distribution of the guide groove 24 allows the drive rod 28 to slide along the guide groove 24 during the rotation of the adjusting roller 23, thereby pulling the longitudinal grid bar 14 to move laterally within the grid member 100, and realizing the adjustment of the grid bar gap.

[0033] In this embodiment, the adjustment device 200 further includes a sliding frame assembly, which includes two mounting seats 21, multiple sliding frames 26 and sliding rods 25. The two mounting seats 21 are symmetrically arranged on the upper end of the grid member 100, the sliding rods 25 are connected between the two mounting seats 21, the sliding frames 26 are slidably disposed outside the sliding rods 25, and the sliding frames 26 are connected to the lower end of the drive rod 28.

[0034] This design allows the slide frame 26 to slide smoothly on the slide rod 25, while the cooperation between the drive rod 28 and the guide groove 24 ensures that the movement of the slide frame 26 can accurately follow the rotation of the pitch roller 23, thereby achieving precise traction and spacing adjustment of the longitudinal grid bars 14.

[0035] In order to realize the function of the drive component, the drive component in this embodiment includes a motor 32, two drive wheels 33 and a drive belt 34. The drive belt 34 is tensioned on the two drive wheels 33. One drive wheel 33 is connected to the output shaft of the motor 32, and the other drive wheel 33 is connected to the shaft of the adjusting roller 23. The design of the drive wheel 33 is used to change the output transmission position, which facilitates the setting of the motor 32.

[0036] When the motor 32 starts, its output shaft drives one drive wheel 33 to rotate. Through the transmission belt 34, the other drive wheel 33 rotates accordingly, which in turn drives the shaft of the adjusting roller 23 to rotate. This transmission method can not only effectively transmit power, but also flexibly adjust the installation position of the motor 32 according to the actual installation space and layout requirements, thus improving the adaptability and maintainability of the entire device.

[0037] In this embodiment, a screw frame 27 is provided at the lower end of the sliding frame 26, and the longitudinal grid 14 is connected to the screw frame 27 by bolts screwed to its upper end. This connection method is not only simple in structure, but also easy to disassemble and install, so that when the longitudinal grid 14 needs to be maintained or replaced, it can be operated quickly, thereby improving the maintenance efficiency of the equipment.

[0038] In this embodiment, the guide groove 24 is divided into two symmetrically arranged groups along the length of the adjusting roller 23, and the arc direction of both groups is towards the middle section of the adjusting roller 23.

[0039] Understandably, this symmetrical distribution design allows the adjusting roller 23 to transmit power evenly during rotation, ensuring the smooth movement of the sliding frame assembly and thus achieving precise adjustment of the spacing of the longitudinal grid bars 14.

[0040] Furthermore, a bearing seat 22 is provided on the mounting base 21, and the adjusting roller 23 is rotatably mounted above the sliding frame assembly via the bearing seat 22. A mounting plate 31 is provided on one bearing seat 22, and the motor 32 is mounted on the mounting plate 31. This installation method not only improves the stability of the adjusting roller 23, but also makes the installation and maintenance of the motor 32 more convenient, further enhancing the practicality and reliability of the entire device.

[0041] In practical applications, when it is necessary to adjust the spacing of the grid bars to adapt to different sewage treatment needs, the motor 32 is started. The motor 32 drives the adjusting roller 23 to rotate through the transmission belt 34 and the transmission wheel 33. The rotation of the adjusting roller 23 causes the guide groove 24 on its surface to change displacement, which in turn pulls the sliding frame group connected to the guide groove 24 to slide on the slide rod 25. The sliding of the sliding frame group drives the longitudinal grid bars 14 to move laterally within the grid component 100 through the screw frame 27 and bolts, thereby changing the spacing between adjacent longitudinal grid bars 14. By controlling the rotation angle and direction of the motor 32, stepless adjustment of the grid bar spacing can be achieved, so that the adjustable grid component can flexibly cope with the size and shape of impurities in various sewage, improve interception efficiency and sewage treatment effect.

[0042] In this document, the directional terms such as front, back, top, and bottom are defined according to the positions of the components in the accompanying drawings and the positions between the components, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary accordingly depending on different methods of use and placement. The use of these directional terms should not limit the scope of protection claimed by this utility model.

[0043] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
