Abstract

The utility model discloses an ejector used for diluting the chemical solvent with high consistence such as hydrochloric acid or alkali, etc. The utility model consists of a body and a nozzle, wherein, an upper section of the body takes the shape of a cylinder; a lower section of the body is a taper pipe with large upper part and small lower part; the internal chambers of the upper and the lower sections are communicated; the side wall of the upper section is provided with a solution inlet. The nozzle is a reverse taper pipe with large upper part and small lower part; the lower end of the nozzle is inserted into an upper section of the body and is provided with a clearance between the connection points of the upper and the lower sections; the upper end of the nozzle is connected with the upper end of the body in a sealing way. When the ejector of the utility model is used for diluting the hydrochloric acid or alkali solution, the work procedure is little, the operation is easy, and the production efficiency is improved.

Description

Injector

(1) technical field

The utility model relates to a kind of injector that chemical solvents such as the hydrochloric acid of higher concentration or alkali are diluted of being used for.Be applicable to industries such as chemical industry, medicine, generating, printing and dyeing and environmental protection.

(2) background technology

In industries such as chemical industry, medicine, generating, printing and dyeing and environmental protection, for avoiding the service life of boiler inner wall fouling, the prevention bursting of boilers, prolonged boiler, need the running water that enter in the boiler be filtered, with elimination calcium ion, sodium ion and magnesium ion etc. wherein.For this reason, just need filter be installed in the water inlet of boiler.This filter contains a container, is filled with the resin particle as filtering material in the container.During to boiler fills, running water at first enters filter, and calcium ion wherein, sodium ion and magnesium ion etc. add in the boiler after resin particle absorbs again.

Though adopt calcium ion, sodium ion and the magnesium ion of said method in can the elimination running water, the time one is long, after the resin in the filter adsorbs calcium ion, sodium ion and magnesium ion too much, can variable color and lose filtration.At this time, just need clean resin particle.Method commonly used is to be that 2.5～5% hydrochloric acid or aqueous slkali clean resin particle with concentration.And hydrochloric acid on the market or alkaline concentration can use after must diluting mostly more than 30%.

If adopt with hydrochloric acid or aqueous slkali and water according to certain ratio add mix in the container after, add the traditional dilution process in the filter again, not only operation many, be difficult to operate, and production efficiency is not high.

(3) summary of the invention

The purpose of this utility model is to provide a kind of injector.Use this injector that hydrochloric acid or aqueous slkali are diluted, not only operation is few, easy to operate, also can enhance productivity.

Above-mentioned purpose of the present utility model is realized by following technical solution:

Injector of the present utility model is characterized in being made of body and shower nozzle.Wherein, the epimere of body is cylindric, and hypomere is up big and down small conical pipe, and upper and lower section intracavity inter-connection has solution inlet port on the sidewall of epimere.Said shower nozzle is up big and down small back taper pipe, its lower end insert in body epimere and and upper and lower section contact of body between leave the gap, be between its upper end and body upper end and seal shape and be connected.

Adopt such scheme, have the following advantages:

Because injector of the present utility model is made of body and shower nozzle, body epimere wherein is cylindric, and hypomere is up big and down small conical pipe, upper and lower section intracavity inter-connection.The soup import is arranged on the sidewall of epimere.Said shower nozzle is up big and down small back taper pipe, its lower end insert in body epimere and and upper and lower section contact of body between leave the gap, be between its upper end and body upper end and seal shape and be connected.As long as the high pressure running water is squeezed into body from the upper end of shower nozzle, the hydrochloric acid of higher concentration or aqueous slkali will be inhaled into body automatically and mix with running water automatically, thereby come at body lower end outlet ejection uniform low concentration hydrochloric acid of dilution or aqueous slkali.If the lower end of body is communicated with the solution inlet port of filter, just can the resin particle in the filter be cleaned.Not only operation is few, easy to operate, also can enhance productivity greatly.

Fig. 2 is an injector of the present utility model when work and connection status schematic diagram such as filter.

(5) specific embodiment

As shown in Figure 1, injector of the present utility model is made up of body 2 and shower nozzle 1.Body 2 epimeres wherein are cylindric, and hypomere is up big and down small conical pipe, and upper and lower section intracavity inter-connection is processed with a solution inlet port on the sidewall of epimere.Said shower nozzle 1 is up big and down small back taper pipe, its lower end insert in body 2 epimeres and and upper and lower section contact of body 2 between leave the gap.The solution inlet port place of the upper end of body 2, lower end, epimere and the upper end of shower nozzle 1 all are processed with flange, are connected with pipeline 4 being used for.Wherein, be sealing shape Joint by securing member and sealing ring between the flange of the flange of shower nozzle 1 upper end and body 2 upper ends.

See Fig. 2, injector of the present utility model in working order down, its lower end is connected with the filter 3 that anion-cation exchange resin is housed by the solution inlet port on pipeline 4 and filter 3 upper portion side wall, and the upper end joins with water tank (or running water pipe) 7 by water pump 6 and pipeline 4.Solution inlet port on the body 2 epimere sidewalls is communicated with the hydrochloric acid that fills higher (30%) concentration or the container 5 of aqueous slkali by pipeline 4.Upper and lower end at filter 3 also is respectively arranged with water inlet and delivery port.When need clean the anion-cation exchange resin in the filter 3, at first open water pump 6, become water under high pressure from the running water in the water tank (or running water pipe) 7 through water pump 6, this water under high pressure enters shower nozzle 1 and can produce negative pressure after shower nozzle 1 ejection, suck in the body 2 and mix thereby will be in the hydrochloric acid of higher (30%) concentration in the cubitainer on the injector of the present utility model 5 or aqueous slkali, be diluted to the hydrochloric acid or the aqueous slkali of lower (2.5～5%) concentration with running water.The hydrochloric acid of low concentration or aqueous slkali are discharged from body 2 lower ends and are admitted in the filter 3 by pipeline 4, after the anion-cation exchange resin in the filter 3 is cleaned, discharge from the delivery port of filter 3 lower ends at last.
