Claims.
Injector jets, as in pickling tanks, ore digestion, sludge acid treating, etc., particularly where steam is the gasiform fluid injected in contact with the liquid, tend to occasion more or less hammering. This is alwaysobjectionable on account of the noise, and is detrimental and in many cases destructive to the piping and tank equipment. In accordance with the present invention, however, a construction may be had which eliminates hammering, and which in general is particularly durable, even with liquids of highly corrosive character.
To the accomplishment of the foregoing and related ends, the invention, comprises the features of construction set out in the following description, the annexed drawing and the accompanying description including but one of the various forms in which the principl of the invention may be employed.
In the said annexed drawing:
Fig. l is a side elevational view showing the apparatus embodying the invention, as set up in the tank indicated in fragmentary section; and
Fig. 2 is an end elevational view.
customarily, devices of this character have been made of castings, particularly lead, and have necessarily from that fact been conformed to proportions and shaping which have been detrimental in respect to efiiciencies of liquid flow distribution, and the tructures have been particularly subject to crystallization and breakage. In the present invention, the device is formed along lines which we have found to especially meet requirements of hydraulic flowage and at the same time the construction may be made especially durable against corrosive action of liquids with which it may be applied. Thus, with a bell member 2 shaped, as by welding, from sheet stock or plate of Monel, stainless steel or other weldable corrosion-resistant metal selected for the particular application, as by welding, there is assembled a center jet member made up of a pipe 3 which terminates in the nozzle i having a choke 5 through which the gasiform fluid or steam has its inlet. The nozzle and bell are connected by equi-spaced webs 6 which are radially arranged, and which extend for a distance axially of the assemblage at the rear or end 1 of the open bell member 2. If the bell be shaped to a flare proportion such that the flare f, i. e., the difference between the outlet diameter 0 of the bell and the internal diameter 2' mm the ratio of 12 to the flaring length of 37, particularly efficient and quiet operation is obtained. The precise dimensions of the bell may be as desired in view of size of equipment, but whether in terms of a selected fraction of an inch or a centimeter or whatever is adopted, the proportion is desirable as stated. The outward flare of the bell is on an external arc whose radius r is ten times the flare f or 12. A further feature making for increased efficiency is the ratio of the diameter of the center fluid inlet 2" to the bell outlet 0, this being about 4:41. It is desirable also generally to set a ratio of the clearance or length 0 in front of the center fluid inlet 2" in relation to the total bell length l as 32:48, the same standards of measurement adopted being maintained throughout all of the various ratios indicated. With such construction, in operation the central jet bodily propels the liquid in the bell forwardly in uninterrupted smooth pumping action, and depending upon where the device is installed such action thus may forward liquid as desired, and when installed in the general manner as the device in Patent No. 2,008,853, it provides a particularly active circulation in a pickling tank, etc.
On the outside of the bell near its smaller end there may be supporting lugs 8 which permit support or attachment on the floor or wall of the tank or'the like which is equipped. Covering the inlet pipe 3, at least a good part of its length, where corrosive or acid liquids are encountered, and especially at the surf-ace of such liquid as where the liquid level is rapidly fluctuated from boiling, etc., a coatin 9 may be provided such as wiped lead, tin, or other material for additional corrosion resistance.
Depending upon the particular conditions of usage, the device may be mounted at the bottom of the tank, as shown, or it may be suspended in the liquid or be positioned against the tank Wall. In any case, the structure, by its relatively thin walled form and preferred ratios of proportioning, allows an especially effective functioning in pickling sheet metal, dissolving lump chemicals, treating ores, etc., and durability and long life has particularly characterized the construction, along with its efficiency and quietness of operation.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims or the equivalent of such be employed.
We therefore particularly point out and distinctly claim as our invention:
