Abstract

The utility model discloses an unpowered sterilizer which comprises a medicine feeding box, a power water source and a Venturi tube, wherein the Venturi tube comprises a lower-pressure end, a high-pressure end and a negative-pressure end which are communicated mutually; the inner end port of the negative end is arranged at the border of inner end ports of the lower-pressure end and the high-pressure end; the lower-pressure end is communicated with the power water source; the negative-pressure end is communicated with the medicine feeding box; the high-pressure end is communicated with a medicine feeding pipeline; water flows to the high-pressure end from the low-pressure end so as to form negative pressure at the negative-pressure end, thus sucking disinfectant in the medicine feeding box into the high-pressure end; and water and the disinfectant are mixed in the medicine feeding pipeline and then discharged to a sterilizing area. In the utility model, by the arrangement of the Venturi tube, the facilities of mechanical medicine feeding are reduced, the cost is reduced, mechanical materials are prevented from being corroded by liquor, a control system has simple operation and low fault rate without maintenance, the measurement is accurate and the operation is convenient and intuitional.

Description

Unpowered sterilizing machine

Technical field

This utility model designs a kind of unpowered sterilizing machine.

Background technology

Along with The development in society and economy, people improve constantly the requirement of water sterilization, liquid disinfection is the most extensive suitable disinfection way, dosing mode adopts mechanical system or physics mode more, dosage can be thrown in by dosing pump or other mechanical systems, take the method for mechanical system dispensing, to the dispensing facility, control system requires and is strict, and mechanical material must have stronger corrosion resistance and good antioxygenic property, otherwise can be corroded at short notice, wear out, it is inaccurate to cause offeing medicine, even can't normally use, and influences Disinfection Effect.

The utility model content

At the problem that existing situation exists, the purpose of this utility model be to provide a kind of simple in structure, can effectively avoid disinfectant solution to the corrosive unpowered sterilizing machine of facility.

For achieving the above object, the unpowered sterilizing machine of this utility model, comprise dispensing kit, power water source and Venturi tube, wherein, Venturi tube comprises the low-pressure end that communicates with each other, high-pressure side and negative pressure end, the inner port of negative pressure end is arranged on the intersection of the inner port of low-pressure end and high-pressure side, low-pressure end is connected with the power water source, the negative pressure end is connected with dispensing kit, be communicated with administration line set on the high-pressure side, water flows to high-pressure side by low-pressure end, forms negative pressure at the negative pressure end, thereby the disinfectant solution in the dispensing kit is sucked high-pressure side, and water and disinfectant solution mix back row to sterilising zone in administration line set.

Further, the hydraulic pressure at described power water source is not less than 0.2Mpa.

Further, to flow to the angle of the fluid passage of high-pressure side and water (flow) direction be 135 degree to described negative pressure end.

Further, the negative pressure end of described Venturi tube is provided with effusion meter.

This utility model reduces the facility of machinery dispensing by Venturi tube is set, and reduces cost, and avoids medicinal liquid etching mechanism material, and makes that control system is simple to operate, non-maintaining, fault rate is low, accurate measurement, easy to operate directly perceived.

The specific embodiment

As shown in Figure 1 and Figure 2, the unpowered sterilizing machine of this utility model, comprise dispensing kit 1, power water source 2 and Venturi tube 3, wherein, Venturi tube 3 comprises low-pressure end 31, high-pressure side 32 and the negative pressure end 33 that communicates with each other, the inner port of negative pressure end 33 is arranged on the intersection of the inner port of low-pressure end 31 and high-pressure side 32, and negative pressure end 33 flows to the fluid passage of high-pressure side 32 and the angle of water (flow) direction is 135 degree.Low-pressure end 31 is connected with power water source 2, and negative pressure end 33 is connected with dispensing kit 1, is communicated with administration line set on the high-pressure side 32, and this administration line set comprises liquid medicine mixing tube 4 and chemical feed pipe 5.

The hydraulic pressure at power water source 2 is not less than 0.2Mpa, water produces directed flow being not less than under the pressure of 0.2Mpa like this, when water flows to high-pressure side 32 by low-pressure end 31, wait the negative pressure of value in the 33 meeting formation of negative pressure end, disinfectant solution in the dispensing kit 1 can under atmospheric pressure be pressed into high-pressure side 32 automatically, thereby the disinfectant solution in the dispensing kit 1 is sucked high-pressure side 32, because negative pressure end 33 flows to the fluid passage of high-pressure side 32 and the angle of water (flow) direction is 135 degree, help the suction of disinfectant solution so more, make liquid flowing resistance little, having made things convenient for adding of disinfectant solution. liquid medicine mixing tube 4 has certain length, after water and disinfectant solution flow into liquid medicine mixing tube 4, water and disinfectant solution fully mix in liquid medicine mixing tube 4, and pass through chemical feed pipe 5 rows to sterilising zone 6, thereby reaching the effect that no mechanical power mixes dispensing automatically. the negative pressure end 33 of Venturi tube is provided with effusion meter, to be convenient to control the flow of disinfectant solution.

This utility model has solved the etching problem of sterilised liq to disinfection apparatus and control system, the dosing mode of sterilised liq is offerd medicine by the mechanical type of existing technology, change Venturi tube constant voltage gravity flow dosing mode into, reduce the cost of manufacture of disinfection apparatus, avoid disinfectant solution that the corrosion of facility is influenced Disinfection Effect.And by adopting mixing naturally of water and disinfectant solution, increase the water solublity of sterilization medicinal liquid, improved the Disinfection Effect of disinfectant solution.
