Abstract

A spraying device comprises a sequence connection of a high pressure pump, a high pressure pipe, and a pulverization nozzle. The pulverization nozzle comprises a base body, a diamond spout provided with a spraying hole arranged on the middle hole of the head part, and a pulverization needle arranged on the head part of the base body with the needle head coaxial with the spraying hole. The pulverization efficiency of the utility model is high, the pulverization water amount is commonly larger than 200ml/wh, and the pulverization amount is stable.

Description

Sprayer unit

The utility model is a kind of sprayer unit that view is made every profession and trades such as scape, industry, agricultural, animal husbandry that is widely used in.

Sprayer unit be a kind of with liquid by certain method, make its device that is separated into superfine little droplet, at present what use, the reasonable device of atomizing effect mainly is divided into following a few class: 1. supersonic atomizer; 2. centrifugal spraying device; 3. twin fluid atomization device.Below explain with regard to the principle and the existing problems of three kinds of devices:

1. supersonic atomizer: be a kind of ultrasonic wave that produces by electro coupled oscillator, act on the transducing sheet that the empty pressure that its resonance produces spray water, produce the device of atomizing in the instantaneous generation cavitation on every side of having sprayed water.Shortcoming: (1) since operation principle institute extremely, incrustation very easily on the transducing sheet, thus the atomization quantity instability is not even worked: (2) nebulization efficiency is low, and the water yield of atomizing only is 6～10ml/wh; (3) the transducing sheet must be worked under water, and the limitation that is caused is bigger, and some occasion can't be used.

2. centrifugal spraying device: be that a kind of driven by motor water aspirator and atomizing disk of utilizing rotates at a high speed, with water sucking-off from the water storage dish, under action of centrifugal force, water is fractured into granule, and granule high velocity impact atomizing lattice form the device of atomizing through second-time breakage.Shortcoming: (1) nebulization efficiency is low, and the water yield of atomizing is 20～30ml/wh; (2) water owing to not atomizing recycles, and causes the damage ratio of water quality more serious.

3. twin fluid atomization device: be a kind ofly with high-pressure pump compressed air to be produced high-speed friction with the liquid of liquid outlet when high-voltage tube sprays (more than gas speed 200 meter per seconds) at a high speed from atomizer compression ring mouth, frictional force that is produced and shearing force make liquid decompose a kind of device that atomizes.Shortcoming: (1) nebulization efficiency is low, and the water yield of atomizing is 10～20ml/wh; (2) because liquid viscosity is different, atomization quantity can produce respective change along with viscosity-modifying.

In sum, as can be seen, existing atomising device ubiquity nebulization efficiency is low, the unsettled shortcoming of atomization quantity.At the problems referred to above, the utility model provides a kind of nebulization efficiency high, the sprayer unit that atomization quantity is stable.

The scheme that the above-mentioned existing problems that solve the utility model adopt is: connect and compose successively with high-pressure pump, high-voltage tube and atomizer.Described atomizer is made up of matrix, jewel spout and atomization needle.The jewel spout is fixed in the interstitial hole of matrix head, and it is the mist hole of 0.05～0.5mm that the jewel spout has diameter.Atomization needle is at the head of matrix, and its tail end is connected on the matrix, and syringe needle and mist hole concentric are positioned at the front in mist hole, is 1/3～3 times of mist bore dia to the distance in mist hole.

One of layout keeps pipe support below the jewel spout in described interstitial hole, and the jewel spout is had protection support effect.At the jewel spout, keep having between pipe support and the matrix one to fixedly connected pipe, make the jewel spout, keep pipe support to be in it, make processing more convenient.

The nebulization efficiency of this atomising device is higher, and the water yield of atomizing is generally greater than 200ml/wh, and atomizer can reach 500ml/wh for a long time.Atomization quantity is also very stable.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional structure schematic diagram of atomizer.

With reference to Fig. 1, Fig. 2, ZS type high-pressure pump 1 has water inlet, and high-pressure outlet is connected with high-voltage tube 2, and the other end of high-voltage tube 2 is atomizers 3.Atomizer 3 is made up of matrix 4, fixedly connected pipe 10, jewel spout 6, maintenance pipe support 5, atomization needle 9.The hypomere of brass base 4 has external screw thread, and interstitial hole 11 is arranged, and its aperture hypomere is big, and epimere is little.10 1 of fixedly connected pipes have flanging and interior bevelling, and the interstitial hole 11 of its peripheral and matrix 4 epimeres is close-fitting mutually, and flanging is in matrix 4 outsides, with behind matrix 4 close-fittings again with fixedlying connected the outside bevelling in lower end of pipe 10, make 4 one-tenth of itself and matrixes fixedly connected.Patty jewel spout 6 is a ruby, and there is mist hole 7 in the center of circle, and its aperture is 0.15mm, be disposed in bevelling in the pore of fixedly connected pipe 10 below, its circumference with fixedly connected pipe 10 close-fittings.Brass keep pipe support 5 be positioned at jewel spout 6 below, jewel spout 6 is played protection support effect, its peripheral with fixedly connected the pore close-fitting of pipe 10.∩ shape atomization needle 9 afterbodys are fixedly connected on above the matrix 4, syringe needle 8 is facing to the mist hole 7 of jewel spout 6, and with its concentric, the diameter of syringe needle 8 is 0.2mm, syringe needle 8 is 0.05mm to the distance in mist hole 7, arranges screen pack 12 in the interstitial hole 11 of matrix 4 hypomeres.Below 4 μ m, its atomization quantity is very stable at the particle diameter of the water smoke grain 70% that gushes out under the pressure of 80kg, can not change, and when using 1,80 atomizer of high-pressure pump of 1.1KW, its nebulization efficiency can reach 500ml/wh.
