Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, more particularly to a sewage treatment grating machine. BACKGROUND

[0002] In today's society, with the acceleration of industrialization process and the continuous expansion of city scale, sewage discharge continues to rise, and sewage treatment has become a key link in the field of environmental protection. As the front-end pretreatment equipment in the sewage treatment system, the sewage treatment grating machine undertakes the important mission of intercepting various solid impurities in sewage, and its performance has a crucial influence on the efficiency and quality of the whole sewage treatment process.

[0003] The patent document with the application number CN202222756058.1 proposes a sewage treatment grating machine, which cooperates between the collection frame, sealing plate, collection net frame, inlet channel, push plate, push block, connecting rod, reciprocating plate, motor, reciprocating screw rod and stop button. Only by starting the motor can the reciprocating screw rod drive the reciprocating plate to move, and then the push plate moves on the upper end of the grating plate, so that the impurities on the upper end of the grating plate are pushed into the collection net frame inside the collection frame for collection. The worker only needs to pull out the collection net frame to clean the impurities, which is very convenient and improves the work efficiency.

[0004] However, the sewage treatment grating machine proposed in the above document has a single design, limited filtering area, and is difficult to cope with the increasing amount of sewage and complex composition of sewage. The solid impurities in the sewage cannot be fully intercepted, resulting in intensified equipment wear and tear and greatly discounted treatment effect in the subsequent treatment process. The structure is complex, and the assembly is difficult to install and disassemble. When cleaning the intercepted impurities on the grating, a lot of manpower and time are consumed, and when maintaining the internal components, the operation space is limited, which greatly affects the normal operation time and maintenance cost of the equipment.

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a wastewater treatment bar screen, comprising:

[0028] The support assembly 100 includes a bracket 101, a support plate 102 fixedly connected to the end of the bracket 101, a box 103 rotatably mounted on the upper end of the support plate 102, and a baffle 104 hinged to the side wall of the box 103.

[0029] The grille assembly 200 includes a crossbeam 201 fixedly connected inside the housing 103, a slider 202 slidably connected to the side wall of the crossbeam 201, a housing 203 inserted into the side wall of the slider 202, and a grille plate 204 fixedly connected to the inner wall of the housing 203, the grille plate 204 operating inside the housing 103.

[0030] The bracket 101 serves as the basic support structure for the entire wastewater treatment bar screen. The support plate 102 is fixedly connected to the end of the bracket 101, providing an installation support platform for the housing 103. The housing 103 can be flexibly adjusted within a certain angle range to adapt to different wastewater treatment needs. The baffle 104 is rotatable, used to control the communication between the inside and outside of the housing 103. The sliding member 202 is slidably connected to the side wall of the crossbeam 201, allowing it to slide horizontally along the crossbeam 201. This allows wastewater to enter from the bottom of the housing 203 and be filtered by the bar screen 204. Alternatively, impurities that need to be filtered can be stored inside the housing 203 and the bar screen 204 for filtrate treatment.

[0031] Specifically, the grating plate 204 is symmetrically installed on both sides of the housing 203, and the bottom side wall of the housing 203 is provided with a through hole structure that works in conjunction with the grating plate 204.

[0032] The grating plates 204 symmetrically installed on both sides of the housing 203 can increase the filtration area and improve the filtration efficiency.

[0033] Furthermore, the grille assembly 200 also includes a handle bolt 205 threaded to the side wall of the slider 202, the end of the handle bolt 205 passing through the slider 202 and inserted into the middle of the through hole in the side wall of the crossbeam 201.

[0034] The sliding member 202 can be fixed or moved on the crossbeam 201 by tightening or loosening the handle bolt 205.

[0035] Furthermore, the grille assembly 200 is snapped onto the frame 206 on the side wall of the crossbeam 201, and the frame 206 has a mesh structure at equal intervals in the middle that works in conjunction with the grille plate 204.

[0036] The frame 206 serves as an auxiliary filter for the grid plate 204, blocking larger debris.

[0037] Preferably, the frame 206 is symmetrically installed on both sides of the housing 203, and the frame 206 and the housing 203 have the same height.

[0038] The frame 206 can serve as an auxiliary filter for the grating plate 204, and can further block larger debris while providing some protection for the grating plate 204.

[0039] It should be noted that the support assembly 100 also includes a storage box 105 inserted into the inner side of the bottom of the housing 103, and the storage box 105 is installed below the housing 203.

[0040] The storage box 105 is used to collect debris intercepted by the bar screen assembly 200 and can be cleaned separately, reducing the cleaning difficulty of the bar screen machine.

[0041] Preferably, the support assembly 100 further includes a pin 106 threaded to the bottom of the support plate 102, with the end of the pin 106 inserted into the bottom of the housing 103.

[0042] The pin 106 is inserted into the bottom of the housing 103, which can further position and stabilize the housing 103.

[0043] During use, wastewater first flows into the tank 103. During this flow, the wastewater enters through the through-hole at the bottom of the housing 203 and is filtered by the grating plate 204. The grating plate 204 intercepts solid debris in the wastewater, while the clean wastewater continues to flow within the tank 103 through the mesh of the grating plate 204 and the frame 206. When it is necessary to clean the debris intercepted on the grating plate 204, loosen the handle bolt 205 and manually pull the sliding member 202 to slide it along the crossbeam 201, thereby moving the grating plate 204 to a position easy to clean. After cleaning, push the sliding member 202 back to its original position and tighten the handle bolt 205 to secure it. As wastewater treatment progresses, the intercepted debris accumulates on the grating plate 204, and some of the falling debris falls into the storage box 105 below. When the storage box 105 is full, it can be pulled out from the bottom inside of the tank 103 for cleaning. In addition, if it is necessary to perform maintenance or other operations on the components inside the housing 103, the housing 103 can be rotated to adjust its angle, and then the baffle 104 can be opened to facilitate the operator to enter the interior of the housing 103.

[0044] In summary, the grating plates 204 are symmetrically installed on both sides of the housing 203, increasing the filtration area. Combined with the auxiliary filtration function of the frame 206, they can more efficiently intercept solid debris in sewage, improving sewage treatment efficiency and quality. The sliding part 202 is connected to the crossbeam 201 via the handle bolt 205, facilitating the movement and positioning of the grating assembly 200, making it easy and convenient to clean debris from the grating plates 204. The pluggable design of the storage box 105 facilitates the periodic cleaning of intercepted debris. The rotatable design of the housing 103 and the openable design of the baffle 104 provide convenience for internal inspection and maintenance. The cooperation of components such as the bracket 101, support plate 102, and pin rod 106 ensures the stability of the overall structure of the equipment. The grating assembly 200 is connected to the crossbeam 201 through snap-fit ​​and bolt fixing, ensuring the stable operation of the grating assembly during sewage treatment.
