Definitions
- My invention is an improvement in bowls for separating heavy sludges or solids from lighter liquids and discharging them through openings in the bowl wall.
- the object of my invention is to provide, in a bowl with outlets at its maximum diameter for the escape of heavy sludge or slimy solids, simple and reliable means, which may be either automatic 'or under the control of the operator, for opening and for closing such outlets.
- Figure 1 is a vertical section, a little at one side of the center, of a complete bowl.
- Figure 2 is a similar section of a modification.
- Figure 3 is an enlarged cross section of the sludge outlet valve.
- a is a bowl shell having a top b and containing a tubular feed shaft c, a nest of separating discs d and a top disc e.
- the outlet for heavy liquid is at f, for light liquid at g, and for sludge or slimy solids at 1:.
- the bowl is supported and driven by a spindle i turning in a bearing 71.
- the inlet for liquid to be treated is .through a tube It.
- My automatic sludge outlet valve comprises a port at through the bowl wall, a valve seat m at the inner end of the port and an automatically operating floating valve therefor comprising a radially extending hollow body 0 having a pointed head n, the tip of which is adapted to engage the valve seat and through which tip is a small opening 1 throttled by a screw 1'.
- the hollow valve body 0 is slidable radially and may be guided in any suitable manner, as by a tube p extending from near the bowl wall toward the center of rotation.
- the end of tube 2 near the bowl center is closed by a plug s having a stem t that, by entering a hole in the back end wall of the valve body, guides the back end of the' valve body.
- the front end of the valve body may be provided with lugs o to keep it spaced from the enclosing tube.
- the back wall of the valve body is provided with orifices u. There may be any number of these outlets and valve bodies.
- FIG. 2 there is shown, inside the tubular 5 shaft c, a hollow member forming a chamber 1: from the bottom of which lead tubes 10 each adapted to discharge liquid, through the hollow stem t of the plug 3, into the corresponding 1101- r low valve body 0.
- a tube 1/ extending through 10 the center of the feed tube It provides means to feed liquid inside the chamber '0.
- a deflector 2 around the tube 11 near its lower end prevents liquid fed through the tube It entering the chamber 12.
- the radius from the center of the bowl to the inner end of the valve body 0 is less than that of the outlet f for heavy liquid and greater than that of the outlet g for light liquid.
- this bowl is adapted 'for removal of any heavy slimy viscous material from a lighter liquid, such as footsf from the alkali treatment of vegetable oils, dirt from milk, waxes from oils, etc., I will describe its operation when removing from mineral oil the sludge formed by treating 25 such oil with strong acid.
