Description

A remote control scum grab

technical field

The invention relates to the technical field of cleaning devices for sewage treatment plants, in particular to a remote-controlled scum grab.

Background technique

In the sewage treatment project, the sewage enters the factory area through the pipe network, first passes through the interception well, then passes through the coarse screen to salvage the larger scum, then passes through the sewage pump in turn to raise the height of the sewage, and then enters the fine screen to salvage the larger scum. The small scum enters the grit chamber to precipitate and remove the inorganic particles with a relatively large proportion in the sewage, and then passes through the biochemical tank to remove nitrogen and phosphorus in the sewage, and finally enters the final sedimentation tank and filter tank to make the effluent reach the national level. Level 1 standard. When the sewage passes through the coarse grid, on the one hand, a large amount of scum in front of the coarse grid may block the grid, which needs to be cleaned by external force; on the other hand, the scum stuck on the coarse grid will enter the pump chamber, affecting The water pump is working and needs to be cleaned in time. Generally, the cleaning of these scum is mainly manual cleaning, but the underground working space is narrow, the working environment is poor, the operability is poor, muddy, slippery, dirty and smelly, manual cleaning is time-consuming and laborious, and the cleaning cost is high and the efficiency is low. Therefore, there is an urgent need for a scum grabbing device to solve this problem and improve the efficiency of sewage scum treatment.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in accompanying drawing 1-3, the present invention comprises frame 1, left grab bucket 2, right grab bucket 3, hydraulic system 4, control system 5. The through hole in the frame 1 crossbeam is hingedly matched with the bearing pin 6, and the length of the bearing pin 6 is greater than the length of the through hole, and the two ends of the bearing pin 6 stretch out to a certain length outside the through hole of the frame 1 crossbeam; The inside of the grab bucket 3 has a hollow fan-shaped structure. The mounting holes on the fan-shaped straight plate of the left grab bucket 2 and the mounting holes on the fan-shaped straight plate of the right grab bucket 3 are hinged with the pin shaft 6 respectively. The hydraulic system and the control system are installed on the machine. On the frame 1, the control system uses remote control to make the left grab bucket 2 and the right grab bucket 3 swing around the pin shaft 6 under the action of the hydraulic system 4, thereby realizing the opening and closing of the left and right grab buckets.

The hydraulic system includes a motor 401 , an oil pump 402 , an oil tank 403 , a forward oil circuit 404 , a reverse oil circuit 405 , a left oil cylinder 406 and a right oil cylinder 407 . The oil tank 403 is fixed on the frame 1, the motor 401 and the oil pump 402 are installed on the oil tank 403; one end of the left oil cylinder 406 is hinged with the vertical beam of the frame 1, and the other end of the left oil cylinder 406 is installed with the longitudinal reinforcement rib of the left grab bucket 2 The holes are hinged; one end of the right oil cylinder 407 is hinged with the mounting hole on the frame 1 vertical beam, and the other end of the right oil cylinder 407 is hinged with the longitudinal reinforcing ribs of the right grab bucket 3.

The control system includes a battery 501 installed on the frame 1 and an electronic control device connected to the battery; the battery 501 provides electric energy for the motor 401 to drive the entire hydraulic system to work. The electric control device is used to control the work of the motor 401 . There are a lot of records on the electric control device in existing patents, and those skilled in the art can know the structure of the electric control device according to the description of the present invention, which belongs to common knowledge and will not be repeated here.

The bottom plate of the left grab bucket 2 and the bottom plate of the right grab bucket 3 both have rake teeth. After closing, the rake teeth of the left grab bucket 2 and the right grab bucket 3 realize intersecting, and there is a certain distance between the rake teeth and the rake teeth. Clearance, during the grabbing process, the water in the left grab bucket 2 and right grab bucket 3 can flow out from between the rake teeth, and the scum stays in the grab bucket, which plays a certain filtering role and leaves the scum in the grab bucket .

The width of the left grab bucket 2 and the right grab bucket 3 is different. The width of the left grab bucket 2 is slightly larger than the width of the right grab bucket 3. After the left and right grab buckets are installed with the pin shaft, the two sides of the left grab bucket 2 The fan-shaped straight board is on the outside of the fan-shaped straight board on both sides of the right grab bucket 3.

The inside of the left grab bucket 2 and the inside of the right grab bucket 3 are provided with transverse reinforcement bars and longitudinal reinforcement ribs to improve the strength of the grab bucket. Mounting holes for connecting the lower end of the oil cylinder are provided on the plate.

The frame 1 is in an inverted "T" shape, and is welded by two square beams, one horizontal and one vertical. The frame 1 beam is provided with a through hole for installing the pin shaft 6, and the through hole is along the frame beam. The longitudinal direction is set; the two sides of the vertical beam of the frame 1 are provided with mounting holes for connecting with the left oil cylinder 406 and the right oil cylinder 407.

One end of the forward oil circuit 404 is connected to the oil pump, and the other end of the forward oil circuit 404 is respectively connected to the lower end of the left oil cylinder 406 and the lower end of the right oil cylinder 407. The left oil cylinder 406 and the right oil cylinder 407 are controlled by the forward oil circuit 404 Can extend out at the same time; one end of the reverse oil circuit 405 is connected to the oil pump, and the other end of the reverse oil circuit 405 is respectively connected to the upper ends of the left oil cylinder 406 and the right oil cylinder 407, and the left oil cylinder and the right oil cylinder can be controlled by the reverse oil circuit. Retract at the same time.

As shown in Figure 1-3, the remote control scum grab is lifted to the working position by controlling the crane, the battery 501 supplies power to the motor 401 and the electronic control device, the motor 401 drives the oil pump 402, and through the positive oil circuit 404, the The left oil cylinder 406 and the right oil cylinder 407 elongate simultaneously. When the oil cylinders reached the maximum elongation length, the left grab bucket 2 and the right grab bucket 3 were fully closed, and the scum in the water was grabbed during the closing process. The water in the grab bucket 3 leaks from the gap between the rake teeth, and the remote control scum grab bucket is moved to the designated position by controlling the crane, the motor 401 drives the oil pump 402, and through the reverse oil circuit 405, the left oil cylinder 406 and the right oil cylinder 407 Contraction, when the left oil cylinder 406 and the right oil cylinder 407 are fully contracted, the left grab bucket 2 and the right grab bucket 3 are opened, and the scum captured is unloaded at a designated place.

The invention works with its own storage battery, which can not only solve the problems of narrow working space, bad environment, and unsuitability for manual cleaning, but also reduce manpower and material resources, improve sewage treatment efficiency, and greatly save sewage treatment costs.
