Description
Technical Field
[0001] The invention relates to the technical field of municipal sewage engineering, and in particular to an anti-clogging rainwater and sewage diversion device. Background Art
[0002] In urban drainage systems, rainwater and sewage diversion is an important environmental protection technology that can effectively reduce the burden of urban sewage treatment and reduce pollution to the environment. However, traditional rainwater and sewage diversion equipment faces some technical challenges in practical applications, such as equipment blockage, low impurity treatment efficiency, and high maintenance costs. Especially when the amount of rainwater is large or there are many impurities, the diversion equipment is prone to blockage of the screen plate, which affects the smooth discharge of rainwater and even causes frequent shutdowns for maintenance of the equipment, causing considerable trouble to the normal operation of the urban drainage system.
[0003] Most of the rainwater and sewage diversion equipment on the market currently uses fixed screens or simple filtering structures to separate rainwater from impurities. Although the diversion purpose can be achieved to a certain extent, due to the fixedness of the screening structure and the limitations of the screening aperture, the screen is easily blocked by impurities. Especially when facing larger particle impurities such as leaves, sand and gravel, the fixed screen has a poor processing effect and often requires manual cleaning and maintenance, which not only increases labor costs, but may also lead to poor rainwater discharge, which in turn has a negative impact on the operating efficiency of the urban drainage system.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] In one embodiment, referring to Figures 1 to 9, an anti-clogging rainwater and sewage diversion device, comprising a diversion shell 1, a water inlet pipe 2 is arranged on the top of the diversion shell 1, a downpipe 6 is arranged on the bottom of the diversion shell 1, a slag discharge port is opened on one side wall of the diversion shell 1, a slag discharge shell 8 is arranged on one side outer wall of the diversion shell 1, and the opening of the slag discharge port is located inside the slag discharge shell 8; a spacing shielding mechanism 10 is arranged on the top of the diversion shell 1, which is used to control the interval of the water flow flowing into the diversion shell 1 from the water inlet pipe 2; a sieving mesh plate 9 arranged obliquely is movably installed on one side wall of the diversion shell 1, and the sieving mesh plate 9 is arranged on the bottom of the diversion shell 1, and the slag discharge port is opened on the one side wall of the diversion shell 1, and the slag discharge port is opened on the inner side of the slag discharge shell 8; a spacing shielding mechanism 10 is arranged on the top of the diversion shell 1, which is used to control the water flow flowing into the diversion shell 1 from the water inlet pipe 2; a sieving mesh plate 9 arranged obliquely is movably installed on one side wall of the diversion shell 1, and the sieving mesh plate 9 is arranged on the bottom of the diversion shell 1, and the sieving mesh plate 9 is arranged on the bottom of the diversion shell 1, and the sieving mesh plate 9 is arranged on the bottom of the diversion shell 1, and the sieving mesh plate 9 is arranged on the bottom of the diversion shell 1, and the shaving ... The bottom of the screening mesh plate 2 9 is connected to the inner wall of the diversion shell 1 through a spring, and an inclined screening mesh plate 5 is movably installed at one end of the screening mesh plate 2 9, and a telescopic mechanism 16 is provided at the bottom of the screening mesh plate 5 for resetting the swing of the screening mesh plate 5 when the screening mesh plate 5 is impacted by the interval water flow and swings; a limiting protrusion 22 of a triangular prism structure is provided on the side where the bottom of the screening mesh plate 2 9 and the screening mesh plate 5 are close to each other; an anti-blocking mechanism 4 is provided at the bottom of the screening mesh plate 5 for preventing the sieve holes on the screening mesh plate 5 from being blocked.
[0027] When in use, the rainwater to be diverted is fed into the diversion shell 1 through the water inlet pipe 2, and the interval shielding mechanism 10 shields the water end of the water inlet pipe 2 at intervals, so that the rainwater falls into the diversion shell 1 at intervals, and the rainwater falling at intervals impacts on the top of one side of the screening mesh plate 5 at intervals, and the screening mesh plate 5 screens the rainwater, and the impurities in the rainwater slide from the screening mesh plate 15 to the top of the screening mesh plate 29. Under the impact of the rainwater, the screening mesh plate 15 turns downward with the connection between the screening mesh plate 15 and the screening mesh plate 29 as the center of the circle, and the rainwater is filtered. When the screen mesh plate 15 falls down, the screen mesh plate 15 is reset under the support of the telescopic mechanism 16, so that the screen mesh plate 15 swings back and forth in the process of screening the rainwater. At this time, the screen mesh plate 15 drives the rainwater and impurities on the screen mesh plate 15 to swing back and forth, so that the rainwater and impurities on the screen mesh plate 15 can be quickly and effectively separated from the solid and liquid under the action of centrifugal force and inertia during the swinging process, thereby improving the efficiency of rainwater screening and impurity removal, ensuring that the rainwater is screened on the screen mesh plate 15, and avoiding part of the rainwater from The top of the screening mesh plate 1 5 flows to the top of the screening mesh plate 2 9, and in the process of screening rainwater, the screening mesh plate 1 5 can be blown to the sieve holes on the screening mesh plate 1 5 through the anti-clogging mechanism 4 to achieve an anti-clogging effect; and in the early stage of the downward swing of the screening mesh plate 1 5, the screening mesh plate 2 9 will not swing. When the screening mesh plate 1 5 swings downward until the sides of the two limiting protrusions 22 are against each other, the screening mesh plate 2 9 swings downward with the screening mesh plate 1 5 under the driving action of the screening mesh plate 1 5, and the spring controls the up and down swinging of the screening mesh plate 2 9. The screen mesh plate 15 and the screen mesh plate 29 are buffered. When the screen mesh plate 15 is reset upward, the swing amplitudes of the screen mesh plate 15 and the screen mesh plate 29 when they are reset upward are also different, so that the screen mesh plate 15 and the screen mesh plate 29 have a sense of jitter and pause during the swinging process, ensuring that the impurities screened out on the screen mesh plate 15 can be effectively shaken to accumulate on the top of the screen mesh plate 29, and the impurities accumulated on the screen mesh plate 29 fall into the slag discharge shell 8 through the slag discharge port, and the rainwater screened by the screen mesh plate 15 and the screen mesh plate 29 is discharged through the sewer pipe 6, thereby realizing the effective diversion of rainwater and sewage.
[0028] As a preferred embodiment of the present invention, both sides of the screening mesh plate 5 are installed with mounting shells 25 through mounting blocks 24, and the anti-blocking mechanism 4 includes a plurality of air outlet pipes 44 arranged between the two mounting shells 25, and the air outlet pipe 44 is provided with spaced air outlet holes 45 on one side close to the screening mesh plate 5, and both ends of the air outlet pipe 44 are provided with mounting pipes 46, which are penetrated through the mounting shell 25, and the side of the mounting pipe 46 located in the mounting shell 25 is provided with an air inlet hole 47, and the interior of the mounting shell 25 is connected with the interior of the air outlet pipe 44 and the interior of the mounting pipe 46 through the air inlet hole 47.
[0029] As a preferred embodiment of the present invention, the sides of the two mounting shells 25 are each provided with an extension hose 43, a transition shell 42 is installed on the outer wall of the diversion shell 1, and one end of the extension hose 43 away from the mounting shell 25 extends to the interior of the transition shell 42; an air pump 41 is installed on the outside of the diversion shell 1, and the air outlet end of the air pump 41 is connected with the interior of the transition shell 42. When the screening mesh plate 5 filters rainwater, the air pump 41 injects air into the transition shell 42, and the air flow is injected into the mounting shell 25 through the extension hose 43. The air in the mounting shell 25 is injected into the mounting pipe 46 and the air outlet pipe 44 through the air inlet hole 47, and the air in the air outlet pipe 44 is sprayed out through the air outlet hole 45 to exhaust the sieve holes on the screening mesh plate 5 to prevent the impurities filtered out by the screening mesh plate 5 from clogging the sieve holes.
[0030] As a preferred embodiment of the present invention, a fixed rack 23 is installed on the inner wall of one side of the diversion housing 1, and the fixed rack 23 is arranged in an arc shape. A driven tooth 26 is arranged at the circumference of one end of the mounting tube 46 close to the fixed rack 23, and the driven tooth 26 is meshed with the side of the fixed rack 23. The air outlet pipe 44 is a cylindrical structure. When the screening mesh plate 5 swings up and down reciprocatingly, the air outlet pipe 44 and the mounting pipe 46 swing with the swing of the screening mesh plate 5. When the water inlet flow rate of the water inlet pipe 2 is consistent, the swing amplitude and swing trajectory of the screening mesh plate 5 and the screening mesh plate 29 are also fixed. When the mounting tube 46 swings with the screening mesh plate 5, due to the meshing of the driven tooth 26 and the fixed rack 23, the air outlet pipe 44 reciprocates during the swinging of the screening mesh plate 5. During the reciprocating rotation of the air outlet pipe 44, the direction of the air flow ejected from the air outlet 45 changes, and the sieve holes on the screening mesh plate 5 can be blown comprehensively and at multiple angles to effectively prevent the sieve holes from being blocked, and the impurities screened out from the screening mesh plate 5 can be effectively blown away to avoid the impurities being adsorbed on the top of the screening mesh plate 5 and unable to effectively slide onto the screening mesh plate 29.
[0031] As a preferred embodiment of the present invention, a protective cover 21 is provided on one side of the screening mesh plate 5 close to the fixed rack 23, and the protective cover 21 protects the fixed rack 23 to prevent rainwater fed by the water inlet pipe 2 from flowing directly from the gap between adjacent fixed racks 23 to the bottom of the screening mesh plate 5.
[0032] As a preferred embodiment of the present invention, a mounting groove 20 is provided at one end of the screening mesh plate 5 away from the screening mesh plate 29, and an extension plate 19 is installed inside the mounting groove 20 through a spring. During the reciprocating up and down swinging of the screening mesh plate 5, the end of the extension plate 19 extending to the outside of the mounting groove 20 is always against the inner side wall of the diversion shell 1, preventing rainwater from flowing directly from the side of the screening mesh plate 5 away from the screening mesh plate 29 to the bottom of the screening mesh plate 5.

The outer diameter of the shielding component 103 is larger than the inner diameter of the bottom opening of the transition pipe 3, and the shielding component 103 can be pushed to move reciprocally horizontally by the telescopic component 102, and the shielding component 103 reciprocates to shield the bottom opening of the transition pipe 3. When the shielding component 103 blocks the bottom opening of the transition pipe 3, rainwater is retained in the transition pipe 3, and the transition pipe 3 transitions and disperses the rainwater, so that the rainwater is dispersed and falls on the top of the screening mesh plate 5.
