Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a vertical fine screen. Background Technology

[0002] Bar screens are widely used in petrochemical, power, water supply, sewage treatment, and sanitation engineering fields. They are usually installed in the inlet channel of sewage treatment or at the inlet of the collection pool of booster pump stations. When debris or floating objects accumulate to a certain limit, the garbage is picked up manually with rake teeth or other tools. However, conventional bar screens cannot be moved, which makes maintenance inconvenient.

[0003] The existing patent CN209291993U bar screen floats on the water surface via floats. Because the bar screen can slide on the guide rail, its overall height can be automatically adjusted according to the water surface conditions to intercept suspended solids in the water. During the process of the floats moving the bar screen up or down, a second mesh can be placed below the first mesh to block water or placed on one side of the bottom of the first mesh for later use. When the bar screen needs maintenance, it can be easily and quickly inspected by simply lifting it up.

[0004] However, in the process of using the above method, since the mesh size between the grids in the device cannot be adjusted, the grid cannot effectively intercept floating objects of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a vertical fine grid that solves the problem that the grid mesh cannot effectively intercept floating objects of different sizes because the mesh size between the grid meshes in the aforementioned device cannot be adjusted.

[0006] To achieve the above objectives, this utility model provides a vertical fine grid, including a fixing frame, a mounting plate, a grid frame, and an installation device. The mounting plate is fixedly mounted on the fixing frame, the grid frame is fixedly mounted on the fixing frame, and the installation device is mounted on the fixing frame. It also includes an adjustment device, which comprises a horizontal frame, a vertical frame, an adjustment block, a moving component, and a tensioning component. The horizontal frame is fixedly mounted on the grid frame, and the vertical frame is slidably mounted on the horizontal frame. A through groove is provided on one side of the grid frame. The adjustment block is slidably mounted on the grid frame via the moving component and passes through the through groove. Simultaneously, the adjustment block contacts the vertical frame. The tensioning component is mounted on the vertical frame.

[0007] The tensioning assembly includes a telescopic rod and a tension spring. The telescopic rod is fixedly installed on the vertical frame, and the tension spring is disposed inside the telescopic rod.

[0008] The movable component includes a movable plate, a limiting rod, and a rotating component. The limiting rod is fixedly installed on the grid frame. The movable plate is slidably installed on the limiting rod via the rotating component and is fixedly connected to the adjusting block.

[0009] The rotating component includes a screw and a wheel. The screw is rotatably mounted on the grid frame and threaded through the movable plate. The wheel is fixedly mounted on the screw.

[0010] The installation device includes an installation grille and fastening bolts. The installation grille is rotatably mounted on the fixed frame, and the fastening bolts are disposed on the installation grille.

[0011] This utility model discloses a vertical fine grid. In use, the entire device is installed in a suitable position via the mounting plate. The horizontal and vertical frames within the grid frame work together to intercept floating debris. When the grid size needs adjustment, the screw is rotated via the wheel. Since the screw is threaded into the moving plate, its rotation causes the moving plate to move upwards along the limiting rod. The moving plate then moves the adjusting block upwards. At this time, the tension spring within the telescopic rod decreases, causing the telescopic rod to retract and move adjacent vertical frames closer together along the horizontal frame. This reduces the grid size between the horizontal and vertical frames, allowing the adjusting block to be adjusted horizontally via vertical movement. This adjustment enables effective interception of floating debris of different sizes. Attached Figure Description

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The embodiment of this application is as follows:

[0020] Please see Figure 1-4 , Figure 1 This is a schematic diagram of the overall structure of a vertical fine grid according to this utility model. Figure 2 This is a schematic diagram of the installation device of this utility model. Figure 3 This is a schematic diagram of the adjustment device of this utility model. Figure 4 This is a schematic diagram of the connection between the telescopic rod and the tension spring of this utility model.

[0021] This utility model provides a vertical fine grid: including a fixing frame 101, a mounting plate 102, a grid frame 103, and an installation device, and also includes an adjustment device. The adjustment device includes a horizontal frame 104, a vertical frame 105, an adjustment block 106, a moving component, and a tensioning component. The tensioning component includes a telescopic rod 108 and a tension spring 109. The moving component includes a moving plate 110, a limiting rod 111, and a rotating component. The rotating component includes a screw 112 and a wheel 113. The installation device includes an installation grid 114 and fastening bolts 115. The aforementioned solution solves the problem that the grid mesh cannot effectively intercept floating objects of different sizes because the mesh size cannot be adjusted in the aforementioned device. The aforementioned solution can be used in scenarios where the grid mesh size can be adjusted.

[0022] In this embodiment, by moving the adjustment block 106 vertically, the adjustment block 106 can be adjusted horizontally accordingly, thereby adjusting the size of the grid formed by the horizontal frame 104 and the vertical frame 105, which can effectively intercept floating objects of different sizes.

[0023] The horizontal frame 104 is fixedly installed on the grid frame 103, and the vertical frame 105 is slidably installed on the horizontal frame 104. A through groove 107 is provided on one side of the grid frame 103. The adjusting block 106 is slidably installed on the grid frame 103 via the moving assembly and passes through the through groove 107. Simultaneously, the adjusting block 106 contacts the vertical frame 105. The tensioning assembly is installed on the vertical frame 105. Multiple sets of both the horizontal frame 104 and the vertical frame 105 are used, forming a mesh structure. The horizontal frame 104 is provided with a sliding groove, and the adjusting block 106 has a wedge-shaped structure. The moving component can drive the adjusting block 106 to move vertically, and the tensioning component pulls the adjacent vertical frame 105. In use, the moving component drives the adjusting block 106 to move vertically, so that the adjacent vertical frame 105 can be adjusted horizontally with the cooperation of the tensioning component. This allows the size of the grid formed by the horizontal frame 104 and the vertical frame 105 to be adjusted, which can effectively intercept floating objects of different sizes.

[0024] Secondly, the telescopic rod 108 is fixedly installed on the vertical frame 105; the tension spring 109 is disposed inside the telescopic rod 108, and the telescopic rod 108 is composed of two cylindrical structures that can extend and retract with each other. The tension spring 109 is aligned with the axis of the telescopic rod 108. Through the elastic force of the tension spring 109, the telescopic rod 108 causes the two adjacent sets of vertical frames 105 to tend to move closer to each other.

[0025] Furthermore, the limiting rod 111 is fixedly installed on the grid frame 103; the movable plate 110 is slidably installed on the limiting rod 111 through the rotating component and is fixedly connected to the adjusting block 106. The movable plate 110 is provided with threaded holes, and the limiting rod 111 is located on both sides of the movable plate 110. The rotating component can drive the movable plate 110 to move. In use, the movable plate 110 is driven to move vertically along the limiting rod 111 through the rotating component, thereby causing the movable plate 110 to drive the adjusting block 106 to move vertically.

[0026] Furthermore, the screw 112 is rotatably mounted on the grid frame 103 and threaded through the movable plate 110; the wheel 113 is fixedly mounted on the screw 112, the screw 112 is located at the top of the grid frame 103, and the wheel 113 is welded to the end of the screw 112. By rotating the wheel 113, the screw 112 is rotated, and the rotation of the screw 112 will drive the movable plate 110 to move vertically, thereby realizing the movement drive of the movable plate 110.

[0027] Finally, the added grid 114 is rotatably mounted on the fixed frame 101; the fastening bolt 115 is provided on the added grid 114, and the added grid 114 is rotatably engaged with the fixed frame 101 through a hinge. When the floating objects rise with the water level, the added grid 114 is rotated upward so that the added grid 114 abuts against the fixed frame 101, and the upper end of the added grid 114 is locked on the fixed frame 101 by the fastening bolt 115, thereby facilitating the interception of floating objects at different water levels.

[0028] In this embodiment, during use, the entire device is installed in a suitable position using the mounting plate 102. The horizontal frame 104 and the vertical frame 105 within the grid frame 103 work together to intercept floating objects. When the mesh size within the grid frame 103 needs adjustment, the screw 112 is rotated via the wheel 113. Since the screw 112 is threadedly engaged with the moving plate 110, the rotation of the screw 112 causes the moving plate 110 to move upwards along the limiting rod 111. The moving plate 110 then causes the adjusting block 106 to move upwards. At this time, the tension of the tension spring 109 inside the telescopic rod 108 decreases, causing the telescopic rod 108 to retract and drive the two adjacent sets of vertical frames 105 to move closer to each other along the horizontal frame 104. This reduces the mesh size between the horizontal frame 104 and the vertical frame 105. As a result, the vertical movement of the adjusting block 106 allows the adjusting block 106 to be adjusted horizontally accordingly, thereby adjusting the mesh size formed by the horizontal frame 104 and the vertical frame 105 to effectively intercept floating objects of different sizes.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
