Abstract
Abstract Apparatus for producing various construct materials and comprises a vertical container converging from the top down and a vibrator. The container has pipes for feeding a suspension thereinto and discharging a thickened suspension, respectively, and filtering side walls for the passage of filtrate. The vibrator is mounted outside the container and has vibration transmitting planes extending substantially along the filtering side walls of the container in such a manner that they cooperate, during operation of the vibrator, with the filtering side walls to impart vibrations thereto. This facilitates continuous dehydration of the suspension without formation of cake on the filtering surface, whereby a high degree of filtration and a greater filtering rate are ensured.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
An apparatus for dehydration of a continuously fed flow of suspension comprising: a vertical container made converging from top down; a pipe for continuously feeding a suspension to said container; an outlet of said container for discharging thickened suspension therefrom; filtering porous, frusto-conical sidewall means on said container for draining filtrate released from the suspension during its dehydration for obtaining thickened suspension; a vibrator mounted outside said container, frusto-conical vibration transmitting plane means connected to said vibrator contiguous to, parallel to, and spaced apart from said sidewall means for transmitting vibration to said filtering sidewall means during operation of the vibrator; vacuum producing means for continuously draining filtrate from between said sidewall means and said plane means.
Claim 2
Independent Claim
117 words
An apparatus for dehydration of a continuously fed flow of suspension comprising: a vertical container made converging from top down; a pipe for continuously feeding a suspension to said container; an outlet of said container for discharging thickened suspension therefrom; filtering porous, frusto-conical sidewall means on said container for draining filtrate released from the suspension during its dehydration for obtaining thickened suspension; a vibrator mounted outside said container, frusto-conical vibration transmitting plane means connected to said vibrator contiguous to, parallel to, and spaced apart from said sidewall means for transmitting vibration to said filtering sidewall means during operation of the vibrator; vacuum producing means for continuously draining filtrate from between said sidewall means and said plane means.
Claim 3
Dependent Claim
33 words
An apparatus according to claim 1, wherein the vibration transmitting plane means of the vibrator are disposed directly adjacent to the filtering side wall means of the container in close parallel relationship therewith.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 2, wherein the vibration transmitting plane means of the vibrator have longitudinally extending grooves opposite the filtering side wall means.
Claim 5
Dependent Claim
21 words
An apparatus according to claim 1, wherein the filtering side wall means of the container are made of a woven material.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 4, wherein the filtering side wall means of the container are inclined at an angle from 1 to 7.5° to a vertical axis of the container.
Claim 7
Dependent Claim
131 words
Apparatus for dehydrating a continuously flowing suspension comprising, a vertical tubular container for filtering a continuous flow of a suspension, said container having a frusto-conical filtering sidewall means for removing filtrate from the suspension during flow thereof, a vibrator disposed externally of said container, a frusto-conical vibrating plane means connected to the vibrator for continuous vibration thereof disposed parallel to, contiguous to, and spaced apart from said filtering sidewall means for intermittently contacting the filtering sidewall means and imparting vibrations thereto to preclude clogging thereof to insure filtering of filtrate therethrough, means comprising said vertical container for receiving said continuous flow of a suspension, and means for continuously removing a thickened suspension upon removal of filtrate therefrom, and vacuum producing means for continuously draining the filtrate separately from the thickened suspension.
Claim 8
Dependent Claim
131 words
Apparatus for dehydrating a continuously flowing suspension comprising, a vertical tubular container for filtering a continuous flow of a suspension, said container having a frusto-conical filtering sidewall means for removing filtrate from the suspension during flow thereof, a vibrator disposed externally of said container, a frusto-conical vibrating plane means connected to the vibrator for continuous vibration thereof disposed parallel to, contiguous to, and spaced apart from said filtering sidewall means for intermittently contacting the filtering sidewall means and imparting vibrations thereto to preclude clogging thereof to insure filtering of filtrate therethrough, means comprising said vertical container for receiving said continuous flow of a suspension, and means for continuously removing a thickened suspension upon removal of filtrate therefrom, and vacuum producing means for continuously draining the filtrate separately from the thickened suspension.
Claim 9
Dependent Claim
44 words
Apparatus for dehydrating a continuously flowing suspension according to claim 6, in which said container is disposed internally of said means for receiving said flow of a suspension, said vibrating plane means being disposed internally of said sidewall, and said sidewall means diverge downwardly.
Claim 10
Dependent Claim
41 words
Apparatus for dehydrating a continuously flowing suspension according to claim 6, in which said means for receiving said flow of a suspension is said container, and said means for continuously removing the thickened suspension is disposed circumferentially of said sidewall means.
Claim 11
Dependent Claim
36 words
Apparatus for dehydrating a continuously flowing suspension according to claim 6, in which said frusto-conical sidewall means are inclined relative to a vertical axis of said tubular container within a range of from 1° to 7.5°.
