Description

Technical Field

[0001] The utility model relates to the technical field of factory building drainage structures, in particular to a factory building wastewater drainage ditch. Background Art

[0002] When a factory is built, drainage ditches are set up to drain rainwater and production wastewater out of the factory in a timely manner. Existing drainage ditches are basically prefabricated grooves for on-site installation. This method can greatly shorten the construction period and has little pollution to the environment, making it suitable for large-scale promotion.

[0003] However, the existing prefabricated drainage ditch is basically composed of a groove and a grate covering the groove mouth. The function of the grate is to prevent the groove from obstructing the normal passage of pedestrians and vehicles. The holes of the grate are relatively large, and material debris, large particles, etc. in the wastewater will be mixed in the wastewater and enter the drainage pipe. On the one hand, it is easy to cause blockage of the pipe, and on the other hand, it will also increase the workload of the subsequent treatment of the wastewater. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a factory wastewater drainage ditch, including

[0005] A ditch unit, which can be buried underground, is provided with a drainage ditch running through the entire ditch unit along the length direction of the ditch unit, the drainage ditch is U-shaped, and a drainage port is opened at the bottom of at least one group of the ditch units;

[0006] A grate, wherein the grate is integrally sealed at the top opening of the ditch unit, and the grate comprises a grate body, and a water inlet groove for wastewater to flow into is provided on the surface of the grate body; and

[0007] A drainage filter pipe is integrally connected to the drainage port. The drainage filter pipe comprises a drainage pipe in which a filter plate is arranged.

[0008] When the utility model is in use, the ends of the ditch body units are connected to form a complete drainage ditch. Waste water will first enter the ditch body unit through the grate at the mouth of the ditch body unit, flow into the drainage pipe along the drainage ditch, and after being filtered by the filter plate in the drainage pipe, the waste residue will be retained on the upper surface of the filter plate, and the waste water is directly discharged to the outside through the outlet pipe, avoiding the clogging of the outlet pipe by the waste residue.

[0009] Furthermore, a U-shaped connecting groove is provided on the inner wall of the drainage groove at one end of the ditch body unit;

[0010] One end of the groove body unit away from the connecting groove has a convex edge that can be engaged with the connecting groove, and the convex edge is U-shaped.

[0011] The two ditch body units are connected by fitting the U-shaped convex edge into the U-shaped connecting groove. Compared with the end-to-end connection between the ditch body units, this connection method reduces the risk of wastewater leakage from the connection between the ditch body units, and the installation connection is convenient and quick.

[0012] Furthermore, the filter plate can rotate along its own circumference, and a scraper is provided on the upper surface of the filter plate, and the scraper is fixed in the drainage pipe.

[0013] Furthermore, the scraper is S-shaped.

[0014] By rotating the pull rod, the filter plate is driven to rotate. When the filter plate rotates, the fixed scraper will scrape off the waste residue on the upper surface of the filter plate and accumulate it on one side of the scraper, so as to clean up the filter area with no waste residue or a small amount of waste residue on the surface of the filter plate, avoiding the waste residue adhering to the upper surface of the filter plate, causing the filter plate to be blocked and affecting the discharge of wastewater.

[0015] Furthermore, the upper surface of one side of the grate body and the lower surface of the opposite side are provided with an engagement groove. By splicing the grate bodies, it is possible to avoid the grate flipping due to stepping when there is a height difference between the terrain on both sides of the grate adjacent engagement grooves, thereby avoiding injuries to workers.

[0016] Furthermore, a sewage outlet is provided in the drainage pipe corresponding to the position of the scraper, one side of the scraper is connected to the side of the sewage outlet, and the other side extends toward the center of the filter plate and is tangent to the pull rod;

[0017] The drainage ditch also includes

[0018] A sewage discharge unit, which is connected to the sewage outlet, and includes a sewage discharge pipe, a power device and a baffle. The sewage discharge pipe is connected to the sewage outlet, and the baffle is arranged in the sewage discharge pipe. The baffle is driven by the power device to move, so as to realize the opening and closing of the sewage discharge pipe; and

[0019] The sewage collecting tank is arranged under the ground and is connected with the sewage discharge pipe. A sewage collecting tank cover can be sealed at the top of the sewage collecting tank.

[0020] By rotating the pull rod, the filter plate is driven to rotate. When the filter plate rotates, the fixed scraper will scrape off the waste residue on the upper surface of the filter plate, causing it to accumulate on one side of the scraper. As the waste residue continues to accumulate, the accumulated waste residue will squeeze the waste residue pile near the sewage outlet and move toward the sewage pipe. Start the power device, open the baffle, and discharge the waste residue into the sewage collecting tank.

[0021] Furthermore, a sewage collecting box is movably arranged in the sewage collecting trough, and the sewage collecting box is connected to a hoisting device on the ground through a suspension rope.

[0022] The sewage collecting box is below the connection point between the sewage discharge pipe and the sewage collecting trough. The waste residue discharged from the sewage discharge pipe is collected by the sewage collecting box. When the sewage collecting box is full, the winch equipment is started to lift the sewage collecting box out of the sewage collecting trough to process the waste residue in the sewage collecting box.

[0023] The utility model has the following advantages:

[0024] When the utility model is in use, the ends of the ditch body units are connected to form a complete drainage ditch. Waste water will first enter the ditch body unit through the grate at the mouth of the ditch body unit, flow into the drainage pipe along the drainage ditch, and after being filtered by the filter plate in the drainage pipe, the waste residue will be retained on the upper surface of the filter plate, and the waste water is directly discharged to the outside through the outlet pipe, avoiding the clogging of the outlet pipe by the waste residue.

[0025] The two ditch body units are connected by fitting the U-shaped convex edge into the U-shaped connecting groove. Compared with the end-to-end connection between the ditch body units, this connection method reduces the risk of wastewater leakage from the connection between the ditch body units, and the installation connection is convenient and quick.

[0026] By rotating the pull rod, the filter plate is driven to rotate. When the filter plate rotates, the fixed scraper will scrape off the waste residue on the upper surface of the filter plate and accumulate it on one side of the scraper, so as to clean up the filter area with no waste residue or a small amount of waste residue on the surface of the filter plate, avoiding the waste residue adhering to the upper surface of the filter plate, causing the filter plate to be blocked and affecting the discharge of wastewater.

[0027] By splicing the grate bodies, it is possible to avoid the grate flipping due to stepping when there is a height difference between the terrains on both sides of the adjacent interlocking grooves of the grate, thereby avoiding injuries to workers.

[0028] By rotating the pull rod, the filter plate is driven to rotate. When the filter plate rotates, the fixed scraper will scrape off the waste residue on the upper surface of the filter plate, causing it to accumulate on one side of the scraper. As the waste residue continues to accumulate, the accumulated waste residue will squeeze the waste residue pile near the sewage outlet and move toward the sewage pipe. Start the power device, open the baffle, and discharge the waste residue into the sewage collecting tank.

[0029] The sewage collecting box is below the connection point between the sewage discharge pipe and the sewage collecting trough. The waste residue discharged from the sewage discharge pipe is collected by the sewage collecting box. When the sewage collecting box is full, the winch equipment is started to lift the sewage collecting box out of the sewage collecting trough to process the waste residue in the sewage collecting box.

[0047] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0048] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0049] As described in the background technology, the existing prefabricated drainage ditch is basically composed of a groove and a grate covering the groove mouth. The function of the grate is to prevent the groove from obstructing the normal passage of pedestrians and vehicles. The holes of the grate are relatively large, and material debris, large particles, etc. in the wastewater will be mixed in the wastewater and enter the drainage pipe. On the one hand, it is easy to cause blockage of the pipe, and on the other hand, it will also increase the workload of the subsequent treatment of the wastewater.

[0050] Embodiment 1:

[0051] Therefore, in order to solve the above technical problems, this embodiment proposes a factory wastewater drainage ditch, such as Figure 1 As shown, the drainage ditch includes

[0052] A ditch unit 100, which can be buried underground, is provided with a drainage ditch 102 running through the entire ditch unit 100 along the length direction of the ditch unit, the drainage ditch is U-shaped, and a drainage port 103 is opened at the bottom of at least one group of the ditch units;

[0053] The grate 200 is integrally sealed at the top opening of the trench unit 100. Fig. 9 As shown, the grate 200 comprises a grate body 201, and a water inlet trough 202 for waste water to flow into is provided on the surface of the grate body 201; and

[0054] The drainage filter pipe 400 is integrally connected to the drainage port 103. Figure 7 As shown, the drainage filter pipe 400 includes a drainage pipe 401 , and a filter plate 403 is provided in the drainage pipe 401 .

[0055] The filter plate can rotate along its own circumference, and a scraper 402 is provided on the upper surface of the filter plate. The scraper 402 is fixed in the drainage pipe.

[0056] like Figure 8 As shown, the scraper is S-shaped. It can also be designed as a rectangular plate.

[0057] A sewage outlet is provided in the drainage pipe at a position corresponding to the scraper 402, one side of the scraper is connected to the side of the sewage outlet, and the other side extends toward the center of the filter plate and is tangent to the pull rod 404;

[0058] like Figure 1 As shown, the drainage ditch in this embodiment also includes

[0059] The sewage discharge unit 500 is connected to the sewage discharge port. Figure 5 , 6 As shown, the sewage discharge unit 500 includes a sewage discharge pipe 501, a power device 502 and a baffle 503. The sewage discharge pipe 501 is connected to the sewage discharge port. The baffle 503 is arranged in the sewage discharge pipe. The baffle is driven by the power device 502 to move, so as to realize the opening and closing of the sewage discharge pipe 501; and

[0060] The sewage collecting tank 300 is arranged under the ground and is connected with the sewage discharge pipe. A sewage collecting tank cover can be sealed at the top of the sewage collecting tank.

[0061] When the utility model is in use, the ends of each ditch unit are connected to form a complete drainage ditch. The wastewater will first enter the ditch unit through the grate at the mouth of the ditch unit, and flow into the drainage pipe 401 along the drainage ditch. After being filtered by the filter plate 403 in the drainage pipe, the waste residue will be retained on the upper surface of the filter plate, and the wastewater will be directly discharged outward through the outlet pipe, avoiding the waste residue from clogging the outlet pipe. By rotating the pull rod, the filter plate is driven to rotate. When the filter plate rotates, the fixed scraper 402 will scrape off the waste residue on the upper surface of the filter plate, so that it accumulates on one side of the scraper. As the waste residue continues to accumulate, the accumulated waste residue will squeeze the waste residue pile near the sewage outlet to move toward the sewage pipe 501. Start the power device 502, open the baffle, and the waste residue will be discharged into the sewage collection tank 300 through the sewage pipe.

[0062] The baffle can be connected to the sewage pipe through a connecting shaft, and the power device can be a motor, which drives the connecting shaft to rotate and drives the baffle to rotate, so as to open and close the sewage pipe. The power device can also be a cylinder, an electric cylinder or a hydraulic cylinder, which is connected to the connecting shaft through a connecting rod structure, and the connecting shaft is driven to rotate by the extension and contraction of the power device, and then the baffle is driven to rotate, so as to open and close the sewage pipe.

[0063] In addition, if Fig.10As shown, a dirt collecting box 600 may be movably arranged in the dirt collecting tank 300 , and the dirt collecting box 600 is connected to a hoisting device on the ground via a suspension rope 700 .

[0064] The waste collecting box 600 is below the connection point between the sewage discharge pipe and the sewage collecting tank. The waste residue discharged from the sewage discharge pipe is collected by the waste collecting box 600. When the waste collecting box is full, the hoisting device is started to lift the waste collecting box out of the sewage collecting tank to process the waste residue in the waste collecting box.

[0065] Embodiment 2:

[0066] like Figure 3 , 4 As shown, the inner wall of the drainage groove 102 at one end of the ditch body unit 100 in this embodiment is provided with a U-shaped connecting groove 104;

[0067] The end of the groove body unit 100 away from the connecting groove 104 has a convex edge 101 that can be engaged with the connecting groove, and the convex edge is U-shaped.

[0068] The two ditch body units are connected by fitting the U-shaped convex edge into the U-shaped connecting groove. Compared with the end-to-end connection between the ditch body units, this connection method reduces the risk of wastewater leakage from the connection between the ditch body units, and the installation connection is convenient and quick.

[0069] Embodiment 3:

[0070] When the terrain on both sides of adjacent interlocking grooves is uneven (the ground on both sides of the grate is uneven due to human damage, wastewater erosion or vehicle backlog), when workers step on the grate, it may cause the grate to lift up or even flip over, injuring their toes.

[0071] Therefore, if Fig. 9 As shown, the upper surface of one side of the grate body 201 and the lower surface of the opposite side are provided with an engaging groove 203. Through the splicing between the grate bodies, when a grate is stepped on, the grate on the adjacent side will press down the stepped grate under the action of its own gravity. If the stepped grate is to be lifted, the subsequent grate must be lifted together, which increases the stepping force required to lift the grate, thereby reducing the probability of the grate flipping caused by stepping when there is a height difference between the terrain on both sides of the adjacent engaging grooves of the grate, effectively avoiding injuries to workers and improving safety.

[0072] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
