Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a vertical lifting grille machine. Background Art
[0002] The influent of the sewage treatment plant contains debris of uneven sizes. A screen machine will be installed at the water inlet to separate the debris. The existing screen machine has an unsatisfactory ability to separate debris. The debris of different sizes cannot be removed, or some debris enters the downstream with the rotation of the screen machine, and only a small part of the debris can be removed by the screen machine. In addition, the existing screen machines use clean water and high-power water pumps for high-pressure backwashing. The backwashing process will consume a lot of water resources, electricity and water pump equipment. In general, the useful efficiency of the existing screen machines is very low and requires a lot of auxiliary resources to support them.
[0003] In view of the above situation, a vertical lifting screen machine was developed based on the technical update of the existing screen machine. The comb mechanism of this vertical lifting screen machine reciprocates up and down to use the comb teeth to fish out the debris blocked by the screen grate plate. Since the comb teeth and the screen grate plate arranged with longitudinal gaps are always in a cross-coordinated state, the comb mechanism can not only fish out the debris but also clean the gaps of the screen grate plate while reciprocating up and down, so the screen grate plate can always remain transparent, and the density of the screen grate plate can be adjusted according to the amount of impurities in the water. Compared with the traditional screen machine, this vertical lifting screen machine does not need backwashing, which can save the cost of supporting ancillary resources and can better clean impurities in sewage.

When the traction chain (3) moves upward, the traction comb mechanism (5) moves upward, and at the same time, the hydraulic oil pipe (104) is synchronously wound around the oil pipe collecting hub (101). A spring is arranged inside the oil pipe collecting hub (101). When the traction chain (3) moves downward, the comb mechanism (5) moves downward under the action of its own weight, thereby realizing the up and down cyclic movement of the comb mechanism (5). A hydraulic system (1) is arranged on the top of the vertical lifting mechanism (2). The hydraulic pump (103) in the hydraulic system (1) provides hydraulic power to pump the hydraulic oil in the hydraulic oil tank (102) into the hydraulic oil tank (102). The power is transmitted to the hydraulic motor (501) in the comb tooth mechanism (5) through the hydraulic oil pipe (104).

[0030] Working principle of this embodiment: After the vertical lifting grille machine is installed in place, the initial state is first set. The comb mechanism is located at the bottom of the grille machine, the comb teeth are in a fully extended state, and the receiving plate in the unloading flap mechanism is in a fully opened state. The above is the initial state setting. From then on, all the incoming water will enter the downstream after being filtered by the grille grate plate. The vertical lifting grille machine is started after setting the intermittent time in the initial state. At this time, the grille machine is in a non-action standby state, and the automatic control system starts an intermittent countdown. After the intermittent countdown ends, the vertical lifting mechanism starts first to pull the comb mechanism upward, and the comb teeth in the fully extended state will pick up all the debris intercepted by the grille grate plate. When the comb The tooth mechanism stops when it moves to the top of the grille plate. At this time, the receiving plate starts to close and stops automatically after it is in place. After the receiving plate is completely closed, the comb teeth automatically retract, and the picked up debris is unloaded under the blocking effect of the grille plate. The unloaded debris naturally falls on the receiving plate. When the comb teeth automatically retract into place, the receiving plate begins to automatically open and pour out the debris salvaged by the comb teeth mechanism. Then the vertical lifting grille machine begins to automatically restore to the initial state under the action of the automatic control system, and waits after entering the initial state. The automatic control system starts the intermittent countdown again. This is an operation cycle of the vertical lifting grille machine. The vertical lifting grille machine plays a role in cleaning water debris by repeating this way. The vertical lifting grille machine can adjust the size of the grille plate gap and the interval operation time as needed, so as to play a role in finely filtering impurities in the water.
