[0017] Reference Figures 1 to 4 As shown, the utility model provides a solid-liquid separation device for wastewater treatment that can prevent clogging, including: a box body 1 and a temporary storage box 11, the middle part of the inner cavity of the box body 1 is fixedly connected to the interception rod 3 through a fixed plate 4, and the side of the interception rod 3 is fixedly connected to the auxiliary rod 2 through a through hole, and the electric rod 6 fixedly connected in the box body 1 is located above the interception rod 3, and the telescopic rod of the electric rod 6 is fixedly connected to the moving plate 5, and the lower surface of the moving plate 5 is respectively fixedly connected to the main cleaning plate 8 and the auxiliary cleaning plate 7, and the main cleaning plate 8 and the auxiliary cleaning plate 7 are fixedly connected to the auxiliary cleaning plate 7. The plate 7 is slidably connected to the surface of the intercepting rod 3, and the inner cavity of the box body 1 is symmetrically connected to the limit plate 9, and the lower surface of the limit plate 9 is slidably connected to the upper surface of the movable plate 5. The temporary storage box 11 is fixedly connected to the side of the box body 1, and the discharge port 10 and the return port 14 opened at the upper and lower ends of the temporary storage box 11 are connected to the inner cavity of the box body 1, and the temporary storage box 11 is movably connected to the temporary storage frame 12, and the lower end of the side of the temporary storage frame 12 is fixedly connected to the filter plate 13 relative to the position of the return port 14, and the bottom of the temporary storage frame 12 is symmetrically connected to the auxiliary frame 16.
[0018] In this embodiment, the wastewater to be treated is injected into the interior of the box body 1 through the injection port on the upper surface of the box body 1. Most of the wastewater can quickly pass through the intercepting rod 3 and the auxiliary rod 2, and the remaining wastewater will flow into the temporary storage frame 12 through the discharge port 10, and flow into the interior of the box body 1 from the reflux port 14 through the filter plate 13. The drain pipe valve set at the lower end of the box body 1 is opened, and the wastewater after solid-liquid separation can be input to the next treatment link, and the solid waste in the wastewater to be treated will be intercepted by the intercepting rod 3 and the auxiliary rod 2. Part of the solid waste will automatically slide into the temporary storage frame 12 under the impact of the water flow, and the remaining solid waste will be retained. On the upper surface of the intercepting rod 3 and the auxiliary rod 2, the switch of the electric rod 6 is started, and the telescopic rod of the electric rod 6 pushes the movable plate 5 to move, and the movable plate 5 drives the main cleaning plate 8 and the auxiliary cleaning plate 7 to move synchronously, so that the main cleaning plate 8 and the auxiliary cleaning plate 7 can double clean the interception retained on the upper surface of the intercepting rod 3 and the auxiliary rod 2, so that the solid waste can fall into the temporary storage frame 12, and then open the sealing cover on the upper surface of the temporary storage box 11, and the temporary storage frame 12 containing solid waste can be taken out for corresponding cleaning, thereby effectively reducing the probability of blockage of the device when separating wastewater into solids and liquids, and improving the solid-liquid separation efficiency of wastewater treatment.
[0019] As a preferred embodiment, there are two sets of fixing plates 4. Both sets of fixing plates 4 are in a strip-shaped structure, and the cross-section of the fixing plate 4 is in a right trapezoidal structure, while the upper surface of the fixing plate 4 is in an inclined surface structure. At the same time, a plurality of fixing grooves are arranged on the upper surface of the fixing plate 4 at equal intervals in parallel along the length direction, and the fixing grooves are in an arc-shaped structure.
[0020] In this embodiment, as Figure 1 and Figure 2 , the setting of the fixing plate 4 enables the interception rod 3 to be quickly and fixedly connected in the box body 1, and the opening of the fixing groove can enhance the stability of the fixed connection between the fixing plate 4 and the interception rod 3. At the same time, the inclined surface structure of the fixing plate 4 facilitates the inclined placement of the interception rod 3 in the box body 1.
[0021] As a preferred embodiment, the interception rod 3 is in a cylindrical structure, and the fixing plate 4 fixedly connects a plurality of interception rods 3 at equal intervals in parallel through the fixing grooves. The interception rod 3 is located on the upper surface of the fixing plate 4, and the interception rod 3 and the fixing plate 4 are combined together to form a square structure with a hole in the middle. At the same time, the inclined downward end of the interception rod 3 faces the discharge port 10.
[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the combination of the interception rod 3 and the fixing plate 4 can perform corresponding solid-liquid separation on the wastewater to be treated. Moreover, the inclined interception rod 3 enables the intercepted solid waste to slide towards the discharge port 10 under the dual action of subsequent water flow impact and gravity, ensuring that the solid waste can fall into the temporary storage frame 12, which is convenient for the subsequent unified removal by workers during cleaning.
[0023] As a preferred embodiment, a plurality of through holes are arranged on the side surface of the interception rod 3 at equal intervals in parallel along the length direction. The through holes are in a cylindrical structure, and the auxiliary rod 2 fixedly connected to the interception rod 3 through the through holes is in a cylindrical structure. The diameter of the auxiliary rod 2 is smaller than the diameter of the interception rod 3. At the same time, the interception rod 3 and the auxiliary rod 2 are combined together to form a grid structure.
[0024] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the setting of the auxiliary rod 2 can not only further enhance the effect of the interception rod 3 on solid-liquid separation of wastewater, but also assist in enhancing the structural strength between adjacent interception rods 3. At the same time, the arc-shaped structure and size settings of the auxiliary rod 2 and the interception rod 3 can reduce the difficulty of subsequent solid waste cleaning.
[0025] As a preferred embodiment, the moving plate 5 is rectangular in structure. On one side of the lower surface of the moving plate 5 close to the electric rod 6, a secondary cleaning plate 7 is fixedly connected. On the other side of the lower surface of the moving plate 5, a main cleaning plate 8 is fixedly connected. A main groove is correspondingly opened on the lower surface of the main cleaning plate 8 at a position corresponding to the intercepting rod 3. The main groove fits the upper surface of the intercepting rod 3, and the depth of the main groove is less than the radius of the intercepting rod 3. At the same time, the main cleaning plate 8 and the main groove together form an E-shaped structure.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the setting of the moving plate 5 enables the main cleaning plate 8 and the secondary cleaning plate 7 to move synchronously. Moreover, the main cleaning plate 8 can be made of a hard material, which can enhance the cleaning effect of the main cleaning plate 8 in pushing the intercepted garbage and can also assist in reducing the probability of deformation and damage of the main cleaning plate 8. At the same time, the setting of the limiting plate 9 can enhance the stability of the moving plate 5 during movement.
[0027] As a preferred embodiment, both the secondary cleaning plate 7 and the main cleaning plate 8 are strip-shaped in structure. A secondary groove is correspondingly opened on the lower surface of the secondary cleaning plate 7 at a position corresponding to the intercepting rod 3. The depth of the secondary groove is greater than the radius of the intercepting rod 3. The lower end of the cross-section of the secondary cleaning plate 7 is an isosceles trapezoid structure. At the same time, the secondary cleaning plate 7 and the secondary groove together form an E-shaped structure.
[0028] In this embodiment, as Figure 1 and Figure 4 , the secondary cleaning plate 7 can be made of an elastic material such as soft rubber, which facilitates the bending of the lower end of the secondary cleaning plate 7 when it contacts the auxiliary rod 2, enabling the lower end of the secondary cleaning plate 7 to slide along the upper surface of the auxiliary rod 2, improving the cleaning effect of the garbage retained on the upper surfaces of the intercepting rod 3 and the auxiliary rod 2.
[0029] As a preferred embodiment, the bottoms of both the temporary storage box 11 and the temporary storage frame 12 are inclined structures. Multiple groups of guiding grooves are equidistantly opened on the inner side surface of the temporary storage frame 12. The guiding grooves are semi-cylindrical in structure. Multiple groups of auxiliary frames 16 are fixedly connected to the bottom of the temporary storage frame 12 in parallel and equidistantly. The cross-section of the auxiliary frame 16 is a U-shaped structure. Multiple groups of reinforcing rods 15 are fixedly connected to the inside of the return port 14 in parallel and equidistantly. The reinforcing rods 15 are cylindrical in structure.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3The filter plate 13 provided in the temporary storage frame 12 allows the wastewater flowing into the temporary storage frame 12 to flow back into the box body 1 smoothly, thereby preventing the solid waste in the temporary storage frame 12 from flowing into the box body 1 again. The setting of the auxiliary frame 16 and the guide groove can ensure that the wastewater can flow smoothly to the reflux port 14, thereby preventing the solid waste in the temporary storage frame 12 from blocking the flow path of the wastewater, thereby reducing the content of the wastewater in the temporary storage frame 12.
[0031] The anti-clogging solid-liquid separation device for wastewater treatment of the utility model cooperates with the fixed plate 4, the intercepting rod 3, the auxiliary rod 2, the temporary storage box 11, the temporary storage frame 12, the electric rod 6 and the movable plate 5, so that the main cleaning plate 8 and the auxiliary cleaning plate 7 can slide over the upper surfaces of the intercepting rod 3 and the auxiliary rod 2 in sequence, and then can effectively clean the intercepted solid waste accordingly, reduce the probability of the device being blocked, and can also reduce the difficulty of garbage cleaning and reduce the cleaning burden of workers.
