Abstract

The utility model discloses a spraying box, in particular to a spraying box which sends the mist by wind, which is used in the spraying of the auxiliary agents of a paper machine, a dyeing machine, etc, and of other liquid; the spraying box comprises a box body and a mist inlet. The spraying box is characterized in that the utility model also comprises an air inlet; the box body is in the multilayer structure, comprising an outer casing and an inner casing; the inner casing is sleeved in the outer casing; the inner casing is provided with an oillet; the outlet of the air inlet is connected with the opening of the outer casing, and the outlet of the mist inlet is connected with the opening of the inner casing. The spraying box of the utility model has reasonable structure; the droplets are effectively prevented from condensing on the inner wall of the box body, and the droplets sprayed outside the spraying area can be absorbed. When the spraying box is used in the technology of spraying, the existing defects in the prior art can be overcome; so, the effect of spraying is improved, the condensation of the atomized auxiliary agents is reduced, the efficiency is improved, and the energy is saved; the droplets is convenient to recycle, which saves the materials, and keeps the manufacturing environment clean.

Description

A kind of spray tank

Technical field

The utility model relates to a kind of spray tank, particularly a kind ofly is used for the spray tank that wind send spray painting mist method, is used in the auxiliary agent of paper machine, dyeing machine etc. or the spraying of other liquid.

Background technology

Auxiliary agent is all arranged in paper industry and the dyeing and/or return wet spray technology,, spray to the carrier of need spraying liquid with spray nozzle or spray tank then earlier with the auxiliary agent atomizing.Existing spray tank comprises casing 11, fog inlet 12, as shown in Figure 3.Because the droplet particle is little, in light weight, the spray tank of this structure droplet in use directly contacts the inwall of casing, very easily condense at cabinet wall, and droplet can be trickled down outside spraying area; When directly spraying with nozzle, droplet drift phenomenon is just more serious.So not only influenced spraying effect, but also waste material, waste energy, and be unfavorable for cleaner production.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of rational in infrastructure, spray tank that spray effect is good is provided.

The technical scheme in the invention for solving the above technical problem is: this spray tank, comprise casing, fog inlet, its design feature is: also comprise air inlet, described casing is a sandwich construction, contain shell and inner casing, inner casing is enclosed within the shell, inner casing eye with holes, and the outlet of air inlet links to each other with opening on the shell, the outlet of fog inlet links to each other with opening on the inner casing.

Be equipped with around the shell described in the utility model and inhale the mist layer, its upper shed connects bleeding point.

Inner casing described in the utility model adopts the eyelet material, also can adopt Web materials.

The utility model compared with prior art has the following advantages and useful benefit: this spray tank is rational in infrastructure, and at first, its casing adopts inner casing and shell double-decker, and shell is repeatedly kicked into the air port.During use, air inlet connects wind regime, supplies gas between inner casing and shell, causes to form the malleation air cushion between inner casing and the shell, and droplet can't contact the inwall of casing during spraying, can prevent droplet condensing at cabinet wall effectively.Secondly, around shell, be close to the suction mist layer of all attaching bleeding points, during use, make the casing edge form negative pressure, draw the droplet of trickling down outside spraying area by bleeding point.Spray art uses this spray tank can overcome the defective that prior art exists, and improves the effect of spraying, the auxiliary agent that reduces atomizing condenses, and has not only improved efficient, but also has saved the energy.And the absorption of trickling down the droplet outside spraying area, be beneficial to droplet recovery, economical with materials, also be beneficial to the cleaning that keeps production environment.

The specific embodiment

Example structure is referring to Fig. 1,2.This spray tank, its casing 1 adopts sandwich construction, constitutes by inhaling mist layer 2, shell 3, inner casing 4, inhales that mist layer 2 is contained in around the shell 3, shell 3 is enclosed within inner casing 4 outsides; Inhale opening on the mist layer 1 and connect the opening that the opening on bleeding point 8, the shell 3 taps on air port 5, the inner casing 4 and connect fog inlet 6, the top that bleeding point 8 is contained on the limit of casing 1, air inlet 5 and fog inlet 6 all are positioned at casing 1.Bleeding point 8 is generally 1-2, according to casing 1 size, forms the quantity that uniform, enough negative pressure decide bleeding point 8 to guarantee shell 3 edges, and present embodiment is two.The quantity of air inlet 5 to guarantee between the inside and outside shell air intake evenly, can form the malleation air cushion, present embodiment is provided with two.The quantity of fog inlet 6 is according to the width configuration of spray tank, under the situation of subregion control spray amount, the quantity of fog inlet 6 equals the quantity of institute's subregion, adopt the narrowest subregion of the utility model can reach 25 millimeters, subregion is narrow more, casing will design flatly more, to reduce the mixed flow of droplet between each district.Present embodiment is provided with two spraying areas.

The inner casing 4 of embodiment has eyelet 7, adopts the eyelet material, also can adopt Web materials.Casing 1 adopts materials antirust, anticorrosion, stable performance such as stainless steel, plastics to make.Bleeding point 8, air inlet 5, fog inlet 6 are fixed by fixtures such as screw, nuts respectively, or directly are welded on suction mist layer 2, shell 3, the inner casing 4.

During use, bleeding point 8 connect induced-draught fan, air inlet 5 connect air blast, fog inlet 6 connects the atomizing source of the gas.

Claims

1, a kind of spray tank, comprise casing, fog inlet, it is characterized in that: also comprise air inlet, described casing is a sandwich construction, contain shell and inner casing, inner casing is enclosed within the shell, inner casing eye with holes, and the outlet of air inlet links to each other with opening on the shell, the outlet of fog inlet links to each other with opening on the inner casing.
