Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for sewage treatment equipment, specifically an anti-clogging mechanism for sewage treatment equipment. Background Technology

[0002] Wastewater treatment equipment is a key facility used to purify polluted water bodies such as domestic sewage and industrial wastewater. Its core function is to remove impurities, harmful substances and pathogens through physical, chemical and biological technologies, so that the water quality meets the discharge or reuse standards. The main equipment includes: physical treatment equipment (such as bar screens and grit chambers to intercept large particulate impurities), chemical treatment devices (such as dosing systems to adjust pH or flocculation and sedimentation), biological treatment units (such as activated sludge reactors and biofilm reactors to decompose organic matter), and advanced treatment equipment (such as filters and ultraviolet disinfection equipment to improve water quality).

[0003] However, if the screen in the sewage treatment equipment is blocked by debris, the water flow will be obstructed, the load on the subsequent treatment units will be increased, and there is a problem that the screen is prone to clogging, resulting in sewage not being treated in a timely manner. Therefore, it does not meet the existing needs, so an anti-clogging mechanism for sewage treatment equipment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging mechanism for sewage treatment equipment. The internal space of the housing is divided by a grating plate and a guide plate. Sewage enters the housing through the inlet, passes through the grating plate, and is discharged from the outlet along the guide plate. The grating plate traps debris inside the housing. Then, the gate descends to close the outlet, and the grating plate and guide plate move out of the housing. The debris falls naturally under gravity and is discharged from the sludge discharge port, thus preventing clogging of the sewage treatment equipment, improving sewage treatment efficiency, and solving problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging mechanism for sewage treatment equipment, comprising a housing and a U-shaped frame. The U-shaped frame includes a connecting plate, a grid plate, and a guide plate. The connecting plate is located on one side outside the housing. One end of the grid plate and the guide plate are respectively connected to the upper and lower ends of the connecting plate. The other ends of the grid plate and the guide plate extend into the interior of the housing. The housing is a hollow cubic structure with both the upper and lower ends open. The upper and lower ends of the housing are respectively the water inlet and the slag discharge outlet. A water outlet is provided on the side of the housing, a baffle plate is provided on the side of the water outlet, and a gate is provided above the water outlet.

[0006] Preferably, the lower end of the gate is provided with a support plate, the grid plate is composed of a number of grid strips, one end of each grid strip is connected to a connecting plate, and the other end of each grid strip is connected by a crossbar, which is located above the support plate.

[0007] Preferably, the upper end of the gate is provided with a protrusion, and the side of the housing is provided with a first electric telescopic rod, which is fixed to the housing. The piston rod inside the first electric telescopic rod is connected to the protrusion.

[0008] Preferably, limit blocks are provided on both sides of the gate, and fixing plates are provided on the sides of the two baffles. The fixing plates are provided with limit grooves inside, and the limit blocks are located inside the limit grooves.

[0009] Preferably, the connecting plate has an extension plate on both the left and right sides, and the housing has a second electric telescopic rod on both the left and right sides. The second electric telescopic rod is fixed to the housing, and the piston rod inside the second electric telescopic rod is connected to the extension plate.

[0010] Preferably, a scraper is provided above the grid plate. The scraper has a triangular cross-section and is fixed to the inner wall of the housing. The side of the scraper is in contact with the grid plate.

[0011] Preferably, the grating plate and the guide plate divide the interior of the shell into three parts: upper, middle and lower. After the sewage enters the interior of the shell from the inlet, it passes through the grating plate and is discharged from the outlet along the guide plate.

[0012] Preferably, the grating separates waste from sewage, and the waste passes through the shell and is discharged from the slag outlet.

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

[0014] 1. This utility model divides the internal space of the shell by using a grating plate and a guide plate. Sewage enters the shell from the inlet, passes through the grating plate, and is discharged from the outlet along the guide plate. The grating plate traps garbage inside the shell. When there are signs of garbage clogging the grating plate, the gate descends to close the outlet. Then the grating plate and guide plate move out of the shell, and the garbage falls naturally under gravity and is discharged from the sludge discharge port. This achieves the separation of garbage and sewage, thereby avoiding the clogging of sewage treatment equipment and improving sewage treatment efficiency.

[0015] 2. This utility model features a scraper installed above the grating plate. After the first electric telescopic rod drives the gate to descend along the limiting groove to the outlet and enter a closed state, the second electric telescopic rod drives the U-shaped seat to move, causing the grating plate and guide plate to move to the outside of the shell. As the grating plate moves, the scraper scrapes off the garbage attached to the grating plate, improving the garbage collection rate. At the same time, after the garbage inside the shell is cleaned, the gate and U-shaped frame are reset, and the crossbar at the front end of the grating plate is located on the support plate, which improves the grating plate's ability to resist sewage impact and enhances its stability.

[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] To address the issue of easily clogged screens leading to delayed wastewater treatment, please refer to [link / reference needed]. Figure 1-4 The present invention provides an embodiment of an anti-clogging mechanism for a sewage treatment equipment, comprising a housing 1 and a U-shaped frame 5. The U-shaped frame 5 includes a connecting plate 501, a grid plate 502, and a guide plate 503. The connecting plate 501 is located on one side outside the housing 1. One end of the grid plate 502 and the guide plate 503 are respectively connected to the upper and lower ends of the connecting plate 501. The other ends of the grid plate 502 and the guide plate 503 extend into the interior of the housing 1. The housing 1 is a hollow cubic structure with both the upper and lower ends open. The upper and lower ends of the housing 1 are respectively the inlet 101 and the slag outlet 102. An outlet 6 is provided on the side of the housing 1. A baffle plate 601 is provided on the side of the outlet 6. A gate 3 is provided above the outlet 6.

[0023] A support plate 301 is provided at the lower end of the gate 3. The grid plate 502 is composed of several grid strips. One end of each grid strip is connected to the connecting plate 501, and the other end of each grid strip is connected by a crossbar 505. The crossbar 505 is located above the support plate 301. A protrusion 302 is provided at the upper end of the gate 3. A first electric telescopic rod 2 is provided on the side of the housing 1. The first electric telescopic rod 2 is fixed to the housing 1. The piston rod inside the first electric telescopic rod 2 is connected to the protrusion 302. Limiting blocks 303 are provided on both sides of the gate 3. Fixing plates 7 are provided on the sides of the two baffle plates 601. A limiting groove 701 is provided inside the fixing plate 7. The limiting block 303 is located inside the limiting groove 701.

[0024] Extended plates 504 are provided on both the left and right sides of the connecting plate 501. Second electric telescopic rods 4 are provided on both the left and right sides of the housing 1. The second electric telescopic rods 4 are fixed on the housing 1. The piston rod inside the second electric telescopic rods 4 is connected to the extended plates 504. A scraper 103 is provided above the grid plate 502. The cross-section of the scraper 103 is triangular. The scraper 103 is fixed on the inner wall of the housing 1. The side of the scraper 103 is in contact with the grid plate 502. The grid plate 502 and the guide plate 503 divide the interior of the housing 1 into three parts: upper, middle and lower. After the sewage enters the interior of the housing 1 from the inlet 101, it passes through the grid plate 502 and is discharged from the outlet 6 along the guide plate 503. The grid plate 502 separates the garbage from the sewage.

[0025] When the amount of waste retained affects the efficiency of subsequent sewage passing through the grating plate 502, the first electric telescopic rod 2 drives the gate 3 to descend along the limiting groove 701 to the outlet 6 and enter a closed state. Then, the second electric telescopic rod 4 drives the U-shaped frame 5 to move, causing the grating plate 502 and the guide plate 503 to move to the outside of the shell 1. The waste then falls naturally under gravity and is discharged from the slag discharge port 102. As the grating plate 502 moves, the scraper 103 scrapes off the waste attached to the grating plate 502, improving the waste collection rate and achieving the separation of waste and sewage. This avoids the clogging of the sewage treatment equipment and improves the sewage treatment efficiency. At the same time, after the waste inside the shell 1 is cleaned, the gate 3 and the U-shaped frame 5 are reset in sequence. At this time, the crossbar 505 at the front end of the grating plate 502 is located on the support plate 301, which improves the ability of the grating plate 502 to resist sewage impact and improves stability.

[0026] Working principle: Sewage enters the interior of the shell 1 through the inlet 101, passes through the grating plate 502, and is discharged from the outlet 6 along the guide plate 503. The grating plate 502 traps garbage inside the shell 1. When the amount of garbage trapped affects the efficiency of subsequent sewage passing through the grating plate 502, the gate 3 descends to close the outlet 6. After that, the grating plate 502 and the guide plate 503 are moved out of the shell 1, and the garbage falls naturally with gravity and is discharged from the sludge discharge port 102, thus achieving the separation of garbage and sewage and avoiding the blockage of sewage treatment equipment.
