Abstract

The utility model relates to a water level control device for the ultraviolet disinfection system, comprising a disinfection canal, an overflow tank and an erection hole of the overflow tank. The overflow tank is arranged in the back of the lamp bracket of the ultraviolet disinfection system near the tail end, meanwhile works as the water outlet of the ultraviolet disinfection system; when the increase of the system flow enables the water surface inside the canal higher than the upper surface of the tank, the water above the top surface of the overflow tank flows into the tank across the upper surface of the tank, then is dispersed into the outflow canal of the system through the water outlet of the canal; so the water level inside the canal is maintained between the highest limiting water level of the system and the lowest limiting water level of the system so as to maintain the liquid level. The utility model also can be used in other system needing to control the liquid level.

Description

The UV disinfection system water-level control apparatus

Background technology:

As everyone knows, water channel formula ultraviolet ray disinfecting system need keep certain water level to guarantee Disinfection Effect, surpasses effective sterilization water level if discharge increases, and part water non-sterile is directly discharged, influence general effect, therefore need control water level to make it remain on certain height.In the water channel of existing ultraviolet water disinfection systems, water-level control apparatus commonly used has two kinds of forms, a kind of is installing Single Chip Microcomputer (SCM) system control liquid level, as shown in Figure 1, comprise installing liquid level sensor 4 and level control valve door 5, the normal operation of system is a water level when being no more than level sensing and answering device 4 preset values, and level control valve door 5 is closed; When the water yield increased above preset value, liquid level sensor 4 transmitted signals to single-chip computer control system, and control system is sent instruction, and level control valve door 5 is opened and discharged water, and after the water level recovery was normal, level control valve door 5 was closed.

Another kind is the water delivering orifice that mill weir 14 conduct sterilization channels were set at the end of the water channel of sterilizing, and is crossing installing hydraulic controlled valve 6 maintenance water levels on the mill weir 14, as shown in Figure 2.The normal operation of system is a hydraulic pressure in range of normal value the time, and hydraulic controlled valve (6) is closed, and the water after the sterilization is discharged by crossing the mill weir top.When discharge increased, hydraulic pressure increased, and hydraulic controlled valve 6 is opened and discharged water, and hydraulic pressure recovers normal back hydraulic controlled valve 6 and closes.In above-mentioned two kinds of schemes, need add valve in addition, by pressure control or the liquid level sensor and the Single Chip Microcomputer (SCM) system control of water, system equipment is many, install and the maintenance inconvenience, and reliability is not high.

The utility model content

The purpose of this utility model provides a kind of water-level control apparatus, comprises sterilization water channel, overflow groove and sets up hole and overflow groove.Overflow groove is embedded in the position of the lamp bracket rear of ultraviolet ray disinfecting system near the water channel end.The overflow groove main body is the shape of cuboid groove or other non-rectangular parallelepipeds.The lateral opening of overflow groove links to each other with the water channel that goes out of decontamination system as water delivering orifice.The minimum spacing water level of the end face of overflow groove and ultraviolet ray disinfecting system is at same surface level or a little less than the minimum spacing water level of system, utilize the hydro science principle that the water level in the water channel is remained between the highest spacing water level and minimum spacing water level of system, reach the purpose that keeps liquid level.

The size of overflow groove, number and exhaust position are determined according to the geometrical length of the spacing height of system's peak level, flow system flow variation range and water channel.When flow increases the water surface make in the water channel and is higher than the upper surface of groove, the water that is higher than the overflow groove end face is crossed in the upper surface inflow groove of groove, enter the water channel that of system through the water delivering orifice of groove, when discharge is changed in the design discharge scope, water level in the water channel remain at the highest spacing water level H2 of system and lowest water level spacing between, reach satisfied bactericidal effect.

This device with above-mentioned existing ultraviolet ray disinfecting system in fluid level control device mutually specific energy reliably keep liquid level and need not any electric power and optional equipment, simple in structure, easy care, reliable, safe, energy-conservation.

Embodiment:

The utility model has two kinds of embodiment.

Embodiment is just like Fig. 4.Perforate is set up hole 12 as overflow groove on two sidewalls of sterilization water channel 2, the perforate of one or both sides is split into through hole as water delivering orifice, several overflow grooves 7 are set up along water (flow) direction in rear at ultraviolet disinfection lamp bracket 3, the water delivering orifice 8 of overflow groove 7 extends to the outer wall that overflow groove sets up hole 12, and the water outlet of overflow groove 7 drains into out water channel 9 backs and discharges.

Among the embodiment two as shown in Figure 7 and Figure 8, overflow groove 7 is erected in the water channel, set up hole 12 at two sidewalls of water channel and the terminal perforate of water channel as overflow groove, the overflow groove that overflow groove supporting plate 13 is erected at sterilization canal sidewall sets up on the hole 12, is used to support overflow groove 7.Overflow groove 7 is erected on the overflow groove supporting plate 13 along the water channel direction at the rear of ultraviolet lamp bracket 3, and the overflow groove that the end of overflow groove 7 is erected at sterilization canal end sets up in the hole 12, and the overflow groove of sterilization canal end sets up hole 12 and is split into through hole and is used for water outlet.
