Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for environmental protection. Background Art

[0002] In the environmental protection field, screen filters serve as the core equipment for primary treatment of wastewater. They primarily intercept suspended solids and large particles in wastewater through a fixed bar structure. This type of technology generally uses a static grid design, with the gaps between the bars forming a physical filtration barrier. During use, the existing technology's fixed bar gaps are susceptible to fibrous impurities (such as hair and plant roots) or sticky sludge invading and attaching, leading to progressive clogging. To avoid this, mechanical scraping mechanisms (such as rotating scrapers or reciprocating cleaning brushes) are used to remove accumulated debris. The drive system primarily relies on an external motor or hydraulic system to provide power, which drives the cleaning components through periodic motion via a transmission chain or connecting rod mechanism to achieve basic self-cleaning functions. However, this approach not only results in high energy costs, but also interrupts the entire sewage treatment process in the event of a power outage or mechanical failure, severely limiting the reliability of the device in remote areas or scenarios with unstable power supply. Therefore, we propose a sewage treatment device for environmental protection. Summary of the Invention

[0013] Furthermore, a drain outlet is provided at the lower end of the right side of the L-shaped guide frame, and an inclined guide block is fixed at the lower end of the right side inside the L-shaped guide frame. The inclined guide block guides the filtered sewage to flow in a directional manner, avoids sedimentation and blockage of the drain outlet, thereby improving treatment efficiency and reducing hydraulic loss.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the sewage treatment device for environmental protection has the following advantages: 1. The rotating shaft drives the scraper to slide adaptively in the grille gap due to gravity. The scraper bar can penetrate deep into the grille gap to scrape away fiber impurities. At the same time, the scraper frame performs a secondary cleaning of the surface residue of the scraper component. When the device rotates to the low position, the counterweight block triggers the sealing block to seal some air holes. The high-pressure airflow ejected by the energy storage airbag flushes the scraper frame in a targeted manner, forming a dual cleaning mechanism of "mechanical scraping + air purge", which significantly reduces the risk of sticky sludge and hair impurities invasively adhering to the grille. 2. When sewage flows through the connection box and drives the connecting shaft to rotate, the pulley mechanism synchronously drives two independent systems: one drives the rotating shaft to achieve the grille cleaning function, and the other drives the moving component to reciprocate through the pull rod, converting mechanical energy into compressed gas and storing it in the energy storage airbag. This design allows the device to operate completely based on the kinetic energy of sewage flow, without the need for an external power supply or hydraulic system. The energy conversion, storage and release form an autonomous cycle. 3. The limit assembly composed of the ratchet mechanism and the torsion spring ensures the one-way rotation of the connecting shaft, preventing the equipment from reversing and failing due to water flow fluctuations. The pneumatic cleaning system uses an energy storage airbag to achieve energy buffering, ensuring periodic self-cleaning even when the sewage flow is unstable; 4. The dynamic cleaning mechanism significantly reduces the frequency of manual cleaning. The adaptive design of the gap between the scraper and the grid bar avoids overload damage caused by impurity accumulation. The hydraulic drive replaces the motor transmission system, completely eliminating the risk of motor burnout, gear wear and other failures. Airflow cleaning produces less component friction loss than traditional mechanical brushes. Key components such as barrier mesh bars are made of anti-corrosion materials, and the overall structure has a longer maintenance-free cycle. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the grid assembly 2, the large particle residue in the sewage entering the left end of the L-shaped guide frame 1 is filtered.

[0019] Among them: a material taking port is opened on the left side of the L-shaped guide frame 1, and an L-shaped baffle 10 is slidably connected to the inside of the material taking port.

[0020] Among them: a drain port is opened at the lower end of the right side of the L-shaped guide frame 1, and an inclined guide block 13 is fixed at the lower end of the right side inside the L-shaped guide frame 1. The inclined guide block 13 guides the filtered sewage to flow in a directional manner, avoids sedimentation and clogging of the drain port, improves treatment efficiency and reduces hydraulic loss.

[0021] The working principle of the sewage treatment device for environmental protection provided by the present invention is as follows: after the sewage is injected into the left area of ​​the L-shaped guide frame 1 through the sewage inlet pipe 14, it first flows through the grille assembly 2 for filtration treatment. During this process, the densely distributed grille bars 22 on the fixed bar 21 efficiently intercept large particles of impurities, and the filtered sewage continues to flow to the right. After being accurately guided by the guide plate 12, it is injected into the connection box 82 located below the guide plate 12. The impact force of the water flow drives the connection box 82 to drive the connecting shaft 81 to rotate stably counterclockwise. At this time, the ratchet bar 93 in the limit assembly 9 is firmly engaged with the ratchet under the action of the torsion spring 95. The wheel 84 effectively prevents the reverse phenomenon. The mechanical energy generated by the rotation of the connecting shaft 81 is transmitted to the second connecting wheel ring 74 through the second connecting belt 85, thereby driving the rotating shaft 23 to rotate continuously; at the same time, the second connecting wheel 83 at the front end of the connecting shaft 81 drives the first connecting wheel 73 to rotate through the first connecting belt 72. The rotation of the first connecting wheel 73 pulls the pull bar 65, so that the moving block 61 moves back and forth smoothly along the guide rod 63. When the moving block 61 reciprocates, the rubber plate 52 of the gas injection assembly 5 is pushed to move regularly in the gas injection box 51 through the connecting rod 54: when the rubber plate 52 moves to the left, the gas extraction pipe 55 and the first one-way valve 56 are used. Inhale air; when moving right, the compressed gas is injected into the energy storage air bag 44 through the gas injection pipe 57 and the second one-way valve 58 for storage. At the same time, the rotation of the shaft 23 drives all the scraper plates 25 to rotate. Under the combined action of the sewage impact and the gravity of the counterweight block 27, these scraper plates 25 slide downward along the sliding hole, so that the scraper strips 26 penetrate into the gaps between the grid bars 22 and efficiently scrape off the attached impurities. As the scraper plates 25 and scraper strips 26 move downward, the scraper frame 24 simultaneously removes the residual dirt on its surface. When the shaft 23 rotates to the lower left position of the L-shaped guide frame 1, the left counterweight block 27 drives the scraper plates 25 to continue to move downward, so that the right sealing block 28 The corresponding barrier strips 32 are tightly fitted to form a seal, and the rotating shaft 23 is continued to rotate until the air guide hole 34 is precisely aligned with the air guide pipe 42. The compressed gas in the energy storage airbag 44 is injected into the second air guide channel 33 through the air guide pipe 42, and after being diverted to the two first air guide channels 31, it is forcefully sprayed onto the surface of the scraper frame 24 through the unsealed barrier strips 32, and the residue is completely blown to the accumulation area on the left side of the frame. Finally, the filtered sewage is diverted through the oblique guide block 13 and discharged from the drain port, and the impurities accumulated on the left side can be cleaned by removing the sealing plate 11 and the L-shaped baffle 10. The entire process relies entirely on hydraulic drive to achieve self-circulation and efficient cleaning.
