Abstract
A sieve, comprising outer bars and inner bars and sieving areas with sieving fabric being formed between the outer bars and the inner bars, wherein at least a portion of the outer bars is provided as elastomeric part and at least a portion of the inner bars is provided as elastomeric part, wherein said elastomeric parts can be transferred from a first untensioned state into a second tensioned state. The present invention is furthermore related to a sieve frame to which the sieve can be fixed in a tensioned state, as well as to a sieving device such as a plansifter comprising said sieve and/or sieve frame.
Claims14
A sieve detachably securable to a sieve frame, the sieve comprising:
- at least one outer bar;
- at least one inner bar;
- and,
- a sieving fabric,
- wherein, a portion of the sieving fabric is disposed between the at least one outer bar and the at least one inner bar to form at least one sieving area;
- wherein at least a portion of the at least one outer bar comprises an elastomeric part and at least a portion of the at least one inner bar comprises an elastomeric part;
- and,
- wherein the elastomeric parts are transitionable between a first untensioned state and a second tensioned state.
A sieve frame configured to detachably receive a sieve:
- the sieve frame comprising a side outlet area and a bottom plate, at least one outer profile, and at least one inner profile, wherein the at least one outer profile and at least one inner profile each comprise a respective groove proximate respective upper surfaces thereof,
- the sieve comprising at least one outer bar, at least one inner bar, and a sieving fabric, wherein, a portion of the sieving fabric is disposed between the at least one outer bar and the at least one inner bar to form at least one sieving area, wherein at least a portion of the at least one outer bar comprises an elastomeric part and at least a portion of the at least one inner bar comprises an elastomeric part, and wherein the elastomeric parts are transitionable between a first untensioned state and a second tensioned state,
- wherein, the sieve is detachably securable to the sieve frame by inserting the elastomeric parts of the sieve into the respective grooves of the at least one outer profile and the at least one inner profile of the sieve frame.
A sieving device, comprising:
- a sieve frame comprising a side outlet area and a bottom plate, at least one outer profile, and at least one inner profile, wherein the at least one outer profile and at least one inner profile each comprise a respective groove proximate respective upper surfaces thereof,
- the sieve comprising at least one outer bar, at least one inner bar, and a sieving fabric, wherein, a portion of the sieving fabric is disposed between the at least one outer bar and the at least one inner bar to form at least one sieving area, wherein at least a portion of the at least one outer bar comprises an elastomeric part and at least a portion of the at least one inner bar comprises an elastomeric part, and wherein the elastomeric parts are transitionable between a first untensioned state and a second tensioned state,
- wherein, the sieve is detachably securable to the sieve frame by inserting the elastomeric parts of the sieve into the respective grooves of the at least one outer profile and the at least one inner profile of the sieve frame.
