Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical grilles, in particular to a novel mechanical grille. Background Art
[0002] Mechanical screen is a kind of equipment used in water bodies, sewage treatment, industrial wastewater and other fields. It is mainly used to intercept solid particles, debris and floating objects in the water flow. It is mainly installed at an angle at the inlet of sewage channels, pump house collection wells or at the front end of sewage treatment plants. It is mainly used to intercept coarser floating objects and suspended matter in sewage.
[0003] Mechanical screens are usually composed of a series of parallel metal or plastic grille bars that form a screen structure. The existing Chinese patent with authorization announcement number CN218774379U discloses a mechanical screen that is easy to replace. It is operated by rotating the knob, which drives the threaded rod to rotate, so that the drive block moves away from the knob on the outer wall of the threaded rod. The drive block drives the adjustment block to move synchronously, so that the sealing plate can block the gap between the mechanical screen body and the water channel. However, mechanical screens usually pass water through the grille bars, while solid debris is intercepted between the grille bars. The debris on the screen is grabbed and removed by a grab installed on the material bars. However, the grab of the existing device is often directly fixed to the chain by welding. When the grab is damaged, it is difficult to replace it. In addition, since there is a gap between the mechanical screen and the inner wall of the sewage channel during installation, impurities in the sewage can easily pass through the gap and pass through the screen, affecting the sewage treatment effect.
[0004] In summary, the current new mechanical grilles still have the following defects during installation and use at the user end:
[0005] (1) The grab bucket of existing devices is often directly fixed to the chain using welding technology. When the grab bucket is damaged, it is difficult to replace it;
[0006] (2) When the mechanical screen is installed, there is a gap between it and the inner wall of the sewage channel, which makes it easy for impurities in the sewage to pass through the gap and pass through the screen, affecting the sewage treatment effect. Utility Model Content
[0007] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0033] like Figures 1 to 5As shown together, this embodiment provides a new type of mechanical grille, including a grille body 1 and a chain 2, the chain 2 is symmetrically distributed on both sides of the grille body 1, the grille body 1 is further provided with a water treatment component 3 and a driving component 4, the water treatment component 3 is arranged on the inner side of the grille body 1 through the chain 2, the water treatment component 3 includes a cleaning component 31, the cleaning component 31 includes a grab 311, and welding points 312 are symmetrically provided at both ends of the grab 311, the welding points 312 are fixedly welded on the chain 2, and the welding points 312 correspond to the chain 2 one by one, and the two sides of the grab 311 are also fixedly installed with side blocks 313, and the inner sides of the side blocks 313 are The movable connection is provided with a push rod 314, one end of which extends to the welding point 312. A spring 315 is provided on the outside of the push rod 314, and the spring 315 is located in the grab 311. The welding point 312 is fixed to the corresponding chain 2 by a welding process and can move synchronously with the chain 2. The side block 313 ensures that the grab 311 installed on the inner side of the chain 2 always remains horizontal when following the movement of the chain 2. The push rod 314 can be pushed toward one end of the chain 2 by the extended spring 315, so that the protrusion in the side block 313 is connected with the welding point 312, thereby installing the grab 311 on the inner side of the chain 2.
[0034] A limit block 316 is fixedly installed at one end of the spring 315 near the chain 2. The limit block 316 and the welding point 312 are adapted to each other, and the angle between the limit block 316 and the welding point 312 is ninety degrees. After the push rod 314 and the welding point 312 are completed, the limit block 316 corresponds to the groove in the welding point 312, thereby cooperating with the push rod 314 to complete the clamping connection with the welding point 312, so that the angle of the grab bucket 311 is not easy to change when it moves with the chain 2.
[0035] A protrusion 317 is fixedly installed on the outer side of the top rod 314, and one end of the protrusion 317 protrudes from the top of the side block 313.

[0036] The water treatment component 3 also includes an expansion piece 32, which includes a protective cover 321. The protective cover 321 is symmetrically arranged on both sides of the grille body 1. The inner side of the protective cover 321 is movably connected with an outer baffle 322. The outer baffle 322 is threadedly connected to the protective cover 321 through an adjusting screw 323.

The motor 43 provides power to the transmission wheel 41 through the transmission belt 42 connected to the pulley. The transmission member is completely isolated from the sewage, so that the device runs smoothly.
[0039] When in use, by rotating the adjusting screw 323, the threaded outer baffle 322 moves in the groove opened in the shield 321, and the outer baffle 322 is restricted by the shield 321, and the length of the protruding grille body 1 increases to adapt to the width of the sewage ditch. At the same time, the outer baffle 322 in the inner baffle 324 protrudes in the outer baffle 322 due to gravity, and the length of the outer baffle 322 is extended to adapt to the depth of the sewage ditch, thereby filling the gap between the outer side of the grille body 1 and the sewage ditch, making it difficult for sewage to leak. The transmission belt 42 connected to the pulley is powered by the motor 43 to provide power to the transmission wheel 41, so that the transmission part is completely isolated from the sewage, so that the chain 2 is driven by rotating the transmission wheel 41, so that the welding point 312 connected to the chain 2 moves in the grille body 1, thereby adjusting the grille body. The impurities separated in the body 1 are scraped off, thereby completing the cleaning of impurities in the sewage ditch.
