Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

A construction water classifying, filtering and collecting system as shown in figures 1 and 2 comprises a collecting bucket 1, a filtering bucket 5 and a clarifying tank 11.

The upper end of the collecting barrel 1 is provided with an opening; in this embodiment, the material collecting barrel 1 is preferably a barrel body with an open upper end, and of course, the material collecting barrel 1 in this embodiment may also be a material collecting tank, and the filtering barrel 5 may also be a filtering tank. In order to facilitate the management of a construction site and the utilization of a site area, as shown in fig. 1, a collecting bucket 1 and a filtering bucket 5 are arranged below the construction ground; the clarification tank 11 is arranged above the construction ground.

The bottom of the filter vat 5 is provided with a stirring device 8, in the embodiment, the stirring device 8 is preferably a stirring motor and a propeller, and a filter assembly is arranged above the stirring device 8 in the filter vat 5; the filtering component comprises a filtering net 6, a discharging door 4, a pressure sensor 3 and a chute 2; the filter screen 6 is obliquely arranged in the filter vat 5, the discharge door 4 is electrically connected with the pressure sensor 3 and is arranged on the inner wall of the filter vat 5 opposite to the lower end of the filter screen 6, and a discharge opening communicated with the chute 2 and the upper layer area of the filter screen 6 is arranged at the position of the filter vat 5 corresponding to the discharge door 4; the chute 2 is obliquely arranged on the outer wall of the filter vat 5 corresponding to the discharge door 4; the lower end of the chute 2 is located above the opening of the collecting bucket 1. The discharge door 4 of the present embodiment is an electrically driven door body.

The clarifying tank 11 is communicated with the bottom of the filtering barrel 5 through a water pumping pipe 9, and the water pumping pipe 9 is communicated with a water pumping pump 10; the lower end of the clarifying tank 11 is provided with a sand discharge port 14 and a sand discharge valve, and the side wall of the clarifying tank 11 is provided with a water outlet 13 and a water level sensor 12; the water outlet 13 is provided with a water outlet valve which is electrically connected with the water level sensor 12.

It should be noted that the system of this embodiment further includes a PLC unit electrically connected to the electronic components such as the pressure sensor 3, the discharge door 4, the sand discharge valve, the water level sensor 12, etc., and the PLC unit implements control over each electronic component.

In this embodiment, filter assembly has two, and in practice, filter assembly can be a plurality of, and on filter vat 5 was located to two filter assembly intervals in proper order from top to bottom in this embodiment, two filter assembly's two filter screens 6's sieve mesh number increased from top to bottom in proper order. The inclination angles of the two filter screens 6 are consistent. The filter screen 6 and the horizontal plane form an included angle of 20-30 degrees. I.e. the upper layer of the filter screen 6 is coarse, and can filter larger particles, such as large crushed stones. While the lower layer of filter screen 6 is a fine filter for filtering smaller particles such as sand.

Construction water can be directly discharged into the filter barrel 5 from the upper part of the filter barrel 5, when water flow mixed with particles such as sand, mud and the like passes through the filter screen 6, the particles which cannot pass through are stopped above the filter screen 6 and accumulated at the lower end of the filter screen 6 under the action of gravity, and along with the gradual increase of the filtered particles, the pressure sensor 3 senses corresponding pressure signals and then transmits the pressure signals to a driving part such as a motor of a PLC unit and a discharge door 4, the driving part opens the discharge door 4, the particles corresponding to the filter screen 6 slide into a corresponding chute 2 through a discharge opening and slide into the material collecting barrel 1 from the lower end of the chute 2, and the primary filtration of the construction water and the recovery and cleaning of the sand and the particles are realized; the sand and stone part does not occupy the space in the filter vat 5, the filter vat 5 does not need to be cleaned, the continuity of water inlet in the filter vat 5 is ensured, and the continuity and the efficiency of water treatment are ensured.

The inner wall of the lower end of the chute 2 is provided with a fan-shaped notch 7. The particles can directly fall into the collecting bucket 1 through the fan-shaped notch 7. And traditional chute 2 is because the low end is in complete cambered surface, and the particulate matter is easily piled up in low end department, and along with the increase of the volume that chute 2 high-end got into the particulate matter, the particulate matter of piling up the department increases gradually, seriously influences the unobstructed of chute 2. The fan-shaped breach 7 of this embodiment makes the low side of chute 2 cut apart, and partial particulate matter directly drops from fan-shaped breach 7, and remaining partial particulate matter realizes the reposition of redundant personnel of particulate matter in chute 2 low side landing to collecting vessel 1 behind fan-shaped breach 7 both sides, guarantees the unobstructed of chute 2.

After the water that gets into in the filter vat 5 is filtered out the particulate matter, in the filter vat 5 is together got into along with water to a small part mud, in order to avoid mud to deposit at filter vat 5 bottom, agitating unit 8 of this embodiment can regularly stir (agitating unit 8 includes the clock module of being connected with the PLC unit electricity), thereby take out the mixed liquid of silt and water to in clarification tank 11 through drinking-water pipe 9, clarification tank 11 is used for deposiing this mixed liquid, when the water level of the clear water of upper strata reached level sensor 12's height, level sensor 12 transmits the signal to the PLC unit, the outlet valve of PLC unit control delivery port 13 department is opened, discharge the clear water, realize the cyclic utilization of water. And the settled slurry is discharged through the sand discharge port 14 after the sand discharge valve is opened, so that the automatic cleaning of the clarification tank 11 is realized. Clarification tank 11 is at the drainage in-process, and agitating unit 8 in the filter vat 5 is in quiescent condition, and the water in the filter vat 5 of being convenient for tentatively deposits to when the water in clarification tank 11 is not enough, for its water that supplyes tentatively deposits fast. Compare in current sedimentation tank, the system of this embodiment can realize the automatic subregion of water and particulate matter, has solved the problem that traditional sedimentation tank needs regularly to clear up the cell body bottom.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that a person skilled in the art should also recognize that several modifications and decorations can be made without departing from the principle of the present invention, and the protection scope of the present invention is also covered.
