Description

Technical Field

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

[0002] Wastewater treatment bar structures are an important component of wastewater treatment systems. They are mainly used to intercept and remove large particulate matter from wastewater, such as branches, plastics, paper, and grease. By removing large particulate matter, these substances are prevented from entering subsequent wastewater treatment equipment, reducing equipment wear and clogging. This reduces the solid matter content in the water, which is beneficial for subsequent sedimentation and filtration processes. The bar is made of stainless steel, which has strong corrosion resistance.

[0003] The patent with publication number CN207581389U discloses a height-adjustable grating for sewage treatment, including a first grating and a second grating. There are two second gratings, which are respectively arranged on the front and rear sides of the first grating. The bottom of the first grating extends into the gap between the upper and lower parts of the second grating. The first grating is provided with first support rods on both the left and right sides. The first support rods are fixedly connected to the first grating by connecting blocks. Limiting plates are connected to the outer side of the top of the first support rods. The second grating is provided with second support rods at both the left and right ends.

[0004] The aforementioned technology uses pins to connect the first and second support rods, which can effectively adjust the overall height of the grating. Connecting the connecting through holes of different heights on the first support rod with the limiting through holes on the second support rod using pins can achieve overall height adjustment. However, when frequently adjusting the height of the grating, it is necessary to repeatedly disassemble and insert the pins, which is a cumbersome process. The pin connection may be affected by external vibrations and impacts, causing the pins to fall off or change position, thus affecting the overall height adjustment effect of the structure. Therefore, an innovation is needed in this technology. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable sewage treatment bar structure to solve the problems mentioned in the background art, such as the need to constantly disassemble and insert pins, which makes the operation process cumbersome, and the possibility that the pin connection may be affected by external vibration and impact, causing the pin to fall off or change position, thereby affecting the height adjustment effect of the overall structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sewage treatment bar structure, comprising a first bar frame and a first filter screen, the first filter screen being fixedly disposed inside the first bar frame, an L-shaped seat being disposed on one side of the first bar frame, a hydraulic cylinder being disposed on the top of the L-shaped seat, a piston rod being drivenly connected to the output shaft of the hydraulic cylinder, a second bar frame being fixedly installed at one end of the piston rod, a plurality of reinforcing blocks being fixedly installed on one side of the second bar frame, a third bar frame being disposed between the inner walls of the plurality of reinforcing blocks, a reinforcing groove being opened on one side of the first bar frame, a reinforcing rod being disposed inside the reinforcing groove, and a limit block being fixedly installed on one side of the second bar frame.

[0007] As a preferred embodiment of this utility model, a reinforcing block is movably sleeved on one end of the reinforcing rod, and one side of the limiting block is fixedly connected to one side of the reinforcing block.

[0008] As a preferred embodiment of this utility model, the two sides of the third grid frame are respectively fixedly connected to one side of a plurality of reinforcing blocks, and a third filter screen is fixedly installed inside the third grid frame.

[0009] As a preferred embodiment of this utility model, the positions of the two adjacent reinforcing blocks are corresponding, and a second filter screen is fixedly installed inside the second grid frame.

[0010] As a preferred embodiment of this utility model, the reinforcing rod is fixedly installed inside the reinforcing groove, and the aperture of the second filter screen is equal to the aperture of the third filter screen.

[0011] As a preferred technical solution of this utility model, one side of the L-shaped seat is fixedly connected to one side of the first grid frame, and the aperture of the first filter screen surface is smaller than the aperture of the third filter screen surface.

[0012] In a preferred embodiment of this invention, both the second and third grid frames are movable on one side of the first grid frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model incorporates a hydraulic cylinder, piston rod, second grid frame, reinforcing rod, reinforcing block, and limiting block. Upon activation of the hydraulic cylinder, the piston rod, connected to its output shaft, moves up and down, thereby moving the second filter screen up and down. This allows adjustment of the height between the first and second grid frames. As the second grid frame moves, it transmits force to the limiting block, enabling the reinforcing block to move up and down at one end of the reinforcing rod, enhancing the stability of the second grid frame's vertical movement. By adjusting the overall height of the first and second grid frames through hydraulic transmission, the problem of pins easily falling off under external vibration is solved, enhancing the stability of both after height adjustment.

[0015] 2. This utility model incorporates reinforcing blocks, a third grid frame, a third filter screen, and a second filter screen. The pore sizes of both the second and third filter screens are larger than those of the first filter screen. Therefore, when used together, these three components can perform secondary filtration of impurities in wastewater. The second and third grid frames are connected by multiple reinforcing blocks, ensuring their secure installation. The second and third filter screens have the same pore size. The assembly of the second and third grid frames combines the strength and stability of the two grids, forming a robust overall structure and extending the service life of the grid structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an adjustable wastewater treatment bar structure:

[0023] Example 1:

[0024] like Figure 1-3 As shown, an adjustable wastewater treatment bar structure includes a first bar frame 1 and a first filter screen 2. The first filter screen 2 is fixedly installed inside the first bar frame 1. An L-shaped seat 3 is provided on one side of the first bar frame 1, and a hydraulic cylinder 4 is provided on the top of the L-shaped seat 3. The output shaft of the hydraulic cylinder 4 is drivenly connected to a piston rod 5. A second bar frame 6 is fixedly installed at one end of the piston rod 5. A plurality of reinforcing blocks 8 are fixedly installed on one side of the second bar frame 6. A third bar frame 9 is provided between the inner walls of the plurality of reinforcing blocks 8. A reinforcing groove 15 is opened on one side of the first bar frame 1, and a reinforcing rod 10 is provided inside the reinforcing groove 15. A limiting block 12 is fixedly installed on one side of the second bar frame 6. A reinforcing block 11 is movably sleeved on one end of the reinforcing rod 10. One side of the limiting block 12 is fixedly connected to one side of the reinforcing block 11. The third bar frame 9 has reinforcing bars 10 on both sides of the first bar frame 11. The third grid frame 9 is fixedly connected to one side of multiple reinforcing blocks 8. The third filter screen 13 is fixedly installed inside the third grid frame 9. By setting up a hydraulic cylinder 4, piston rod 5, second grid frame 6, reinforcing rod 10, reinforcing block 11 and limiting block 12, after the hydraulic cylinder 4 is started, it first drives the piston rod 5, which is connected to its output shaft, to move up and down, which in turn drives the second filter screen 7 to move up and down. This allows the height between the first grid frame 1 and the second grid frame 6 to be adjusted. When the second grid frame 6 moves, it transmits force to the limiting block 12, and the reinforcing block 11 can move up and down at one end of the reinforcing rod 10, which enhances the stability of the second grid frame 6 moving up and down. The overall height of the first grid frame 1 and the second grid frame 6 is adjusted by hydraulic transmission, which solves the problem that the pin is easy to fall off when subjected to external vibration, and enhances the stability of the two after the height is adjusted.

[0025] Example 2:

[0026] Based on Example 1, such as Figure 1 and Figure 4As shown, the positions of the two adjacent reinforcing blocks 8 are corresponding. The second filter screen 7 is fixedly installed inside the second grid frame 6. The reinforcing rod 10 is fixedly installed inside the reinforcing groove 15. The aperture of the second filter screen 7 is equal to the aperture of the third filter screen 13. One side of the L-shaped seat 3 is fixedly connected to one side of the first grid frame 1. The aperture of the first filter screen 2 is smaller than the aperture of the third filter screen 13. The second grid frame 6 and the third grid frame 9 are both movable on one side of the first grid frame 1. The reinforcement blocks 8, the third grid frame 9, and the third filter screen 1 are all installed. The apertures of the second filter screen 7 and the third filter screen 13 are all larger than those of the first filter screen 2. Therefore, when used together, they can perform secondary filtration of pollutants in sewage. The second grid frame 6 and the third grid frame 9 are connected by multiple reinforcing blocks 8 to ensure the firmness of the installation of the second grid frame 6 and the third grid frame 9. The apertures of the second filter screen 7 and the third filter screen 13 are the same. The assembly of the second grid frame 6 and the third grid frame 9 can combine the strength and stability of the two grids, thereby forming a solid overall structure and extending the service life of the grid structure.

[0027] Working Principle: The wastewater treatment bar structure is an important component of the wastewater treatment system, mainly used to intercept and remove large particulate matter in wastewater, such as branches, plastics, paper, and grease. By removing large particulate matter, these substances are prevented from entering subsequent wastewater treatment equipment, reducing equipment wear and clogging. This reduces the solid content in the water, which is beneficial for subsequent sedimentation and filtration processes. The bar is made of stainless steel, which has strong corrosion resistance. In the above technology, the height of the overall bar can be adjusted well using pins. However, when frequently adjusting the height of the bar, it is necessary to repeatedly disassemble and insert the pins, which is a cumbersome operation. The pin connection may be affected by external vibration and impact, causing the pins to fall off or change position, thus affecting the height adjustment effect of the overall structure. Therefore, this technology is innovated. After the hydraulic cylinder 4 is started, it first drives the piston rod 5, which is connected to its output shaft, to move up and down, which in turn drives the second filter screen 7 to move up and down, thereby adjusting the height between the first bar frame 1 and the second bar frame 6. When the second grid frame 6 moves, it transmits force to the limiting block 12, allowing the reinforcing block 11 to move up and down at one end of the reinforcing rod 10, thus enhancing the stability of the second grid frame 6's up-and-down movement. The overall height of the first grid frame 1 and the second grid frame 6 is adjusted via hydraulic transmission, solving the problem of the pin easily falling off under external vibration, enhancing the stability after height adjustment, and eliminating the need for frequent disassembly and insertion of the pin, saving workers' time. The apertures of the second filter screen 7 and the third filter screen 13 are both larger than the aperture of the first filter screen 2; therefore, when used together, they can perform secondary filtration of pollutants in sewage. The second grid frame 6 and the third grid frame 9 are connected by multiple reinforcing blocks 8, ensuring the firmness of their installation. The second filter screen 7 and the third filter screen 13 have the same aperture; the assembly of the second grid frame 6 and the third grid frame 9 combines the strength and stability of the two grids, forming a robust overall structure and extending the service life of the grid structure.
