Abstract

The utility model relates to a self-cleaning dense water tank, which belongs to the technical field of water treatment facilities. The self-cleaning dense water tank comprises a box body; a comb teeth shaped compressed air branch pipe and a C-shaped torrent spray pipe are arranged at the lower part of the box body; air outlet holes are distributed on the compressed air branch pipe at intervals; and torrent spray nozzles are mouthed on the torrent spray pipe at intervals. Periodical unartificial operated cleaning can be performed on the dense water tank only by the control of the compressed air and the water flow; the concentrated and the deposited dirt can be removed in a stirring or torrent rinsing manner; the normal operation of the dense water tank is ensured; and the recovery utilization ratio water can be improved.

Description

The dense water tank of self-stip

Technical field

The utility model relates to a kind of dense water tank, and the dense water tank of especially a kind of self-stip belongs to the water processing establishment technical field.

Background technology

In reverse osmosis desalination water treatment operation, the recovery utilization rate that dense water tank can improve system water is set, realize energy-saving and emission-reduction.In actual use, after certain hour is reclaimed in the operation of dense water tank, can a large amount of dirt of deposition in the dense water tank, so just need stop to use as a servant dense water reclamation system, open in manhole door goes into, carry out manually regular cleaning and descaling work, see Fig. 1.And artificial scale removal work not only influences the reuse of dense water, and the repair and maintenance workload is very big.

The utility model content

The purpose of this utility model is: the problem at existing installation exists, and by texture improvement, propose the dense water tank of a kind of self-stip, thereby reduce hand labor intensity, shorten dense water scavenging period.

In order to reach above purpose, the dense water tank of self-stip of the present utility model comprises casing, described lower box is equipped with broach shape pressurized air arm and C shape torrent jet pipe, is intervally distributed with production well on the described pressurized air arm, and described torrent jet pipe is equipped with the torrent nozzle at interval.

Like this, as long as control feeds pressurized air and current, can carry out regular unartificial operation to the dense water tank of operation and clean, in the mode that stirs and torrent wash, remove concentrated, sedimentary dirt dirt in the dense water tank, guarantee the normal use of dense water tank, improve the recovery utilization rate of water.Its advantage can be summarized as follows:

1, makes dense water tank have the self-stip function, do not need manually to open and inspect cleaning;

2, purge stirring with pressurized air,, slow down dense water tank fouling tendency by regular operation;

3, adopt loosening, the souring of torrent nozzle,, guaranteed the normal use of dense water tank by regular operation.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of original dense water tank.

Among the figure: 1---water intaking valve; 2---compressed air inlet valve; 3---the torrent nozzle; 4---blow-off valve; 5---outlet valve; 6---the pressurized air arm; 7---torrent jet pipe water intaking valve 8---wash water valve 9---casings; 10---the female pipe of pressurized air; 11---the torrent jet pipe.

Embodiment

Embodiment one

The dense water tank of the self-stip of present embodiment as shown in Figure 2, water intaking valve 1 is equipped with on casing 9 tops; The pressurized air arm 6 of compressed air inlet valve 2 is equipped with in the bottom, and through the torrent jet pipe 11 of torrent nozzle water intaking valve 7; Blow-off valve 4 is equipped with at the top; Wash water valve 8 is equipped with in the bottom.

Pressurized air arm 6 is the broach shape as shown in Figure 3, above have at interval production well, by connecing compressed air source behind female pipe 10 of pressurized air and the compressed air inlet valve 2, constitute pressurized air stirring pipe device.Torrent jet pipe 11 as shown in Figure 4, and is c-shaped, by torrent jet pipe water intaking valve 7 water receiving sources, is equipped with towards the torrent nozzle 3 that has a down dip at interval along current are tangential.

During work, control feeds pressurized air, can form effective stirring, the torrent flushing then can be removed sedimentary dirt dirt in the dense water tank, the final compressing air becomes flexible the throw out that gets off, by the torrent nozzle further purge, loosening, discharge by wash water valve, thereby guarantee the normal use of dense water tank, improve the recovery utilization rate of water.
