The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
Referring to fig. 1 to 3, the present embodiment provides a sand setting system, which mainly includes a sand suction mechanism, and a water inlet well 1, a grid channel 2, a sand setting tank 3, and a pump room 4, which are connected in sequence.
The grating ditch 2 is internally provided with a device for intercepting large garbage such as wooden sticks, bottles and plastic bags.
A water collecting chamber 41 and water pumps 42 are arranged in the pump room 4, the water collecting chamber 41 is communicated with the grit chamber 3, and a plurality of water pumps 42 connected in parallel are used for pumping water in the water collecting chamber 41. The water collecting chamber 41 can further precipitate the silt in the sewage, and reduce the content of the silt in the sewage entering the water pump 42.
The grit chamber 3 has a groove 31 for settling sand, and the sand and mud in the sewage can settle to the bottom of the groove 31.
The sand suction mechanism is used for extracting and discharging the settled sand in the groove 31, so that the groove 31 of the sand setting tank 3 can continuously play a sand setting role.
After entering the water inlet well 1, the sewage flows through the grid channel 2, the groove 31 of the grit chamber 3 and the water collecting chamber 41 in sequence, and the sewage enters the water collecting chamber 41 of the pump room 4 and is then pumped by the water pump 42. The sludge in the sewage can be settled to the bottom of the groove 31 and the water collecting chamber 41 to reduce the content of the sludge entering the sewage.
The main components and the functioning principle of the sand settling system have been described above in general and will be elucidated in more detail below.
The sand suction mechanism may mainly include a sand sucker 51 having a sand suction pump 511, and preferably, in the present embodiment, the sand sucker 51 is a traveling type sand sucker that can reciprocate along a predetermined track to well suck the muddy sand settled into the trench 31.
The sand setting system may further include a sand discharge pipe 61 and a sand-water separator 62, one end of the sand discharge pipe 61 being communicated with an outlet of the sand suction pump 511, and the other end being communicated with an inlet 621 of the sand-water separator. The sand-water separator 62 can separate the sand and the water pumped by the sand suction pump 511, so as to respectively treat and utilize the sand and the water.
The grit system may further comprise a launder 63, the launder 63 being located below the outlet of the sand discharge pipe 61, the bottom of the launder 63 being in communication with the inlet 621 of the grit-water separator. The reason why the gutter 63 is additionally provided between the outlet of the sand discharge pipe 61 and the inlet 621 of the sand-water separator is that, if the sludge and water pumped by the sand suction pump 511 are ejected from the sand discharge pipe 61 and then directly impact the internal mechanism of the sand-water separator 62, the internal mechanism of the sand-water separator 62 is easily rapidly worn or even deformed by a large impact force over a long period of time, and therefore, the gutter 63 can be additionally provided between the outlet of the sand discharge pipe 61 and the inlet 621 of the sand-water separator so as not to directly impact the sand and water in the sand discharge pipe 61 on the internal mechanism of the sand-water separator 62.
The water outlet 622 of the sand-water separator may flow back into the nearby sump pit or the water collection chamber 41 of the pump house 4 in order to recover this water.
In this embodiment, it is preferable that the trench 31 is plural, and each trench 31 may be provided therein with a sand suction pump 511. The width of the lower portion of the groove 31 (the dimension of the groove 31 in the left-right direction in the state shown in fig. 3) is gradually reduced from top to bottom to better precipitate the sludge in the sewage.
In order to facilitate the transportation of heavy objects such as the water pump 42 in the pump room 4, a travelling crane 43 can be arranged in the pump room 4.
Finally, it should be noted that: the present invention is not limited to the above embodiments, and various modifications and changes can be made to the present invention by those skilled in the art, and the embodiments and features of the embodiments can be combined with each other at will without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
