Description

The invention relates to a drying technique and is intended for drying piece goods, in particular ceramic tubes.

Drying plants are known that contain forms mixed with a help of a vertical-closed conveyor, which are opened (closed) during loading and unloading operations, and heat and ventilation equipment for blowing empty-opened forms.

In order to improve the quality of drying in the proposed drying installation, the forms consist of a hinge on articulated horizontal half-cylinders with moisture absorbing inserts for the inside, and the upper half-cylinder is equipped with a lever that interacts with the roller avker to close the form, disclosed by the effect of its own weight on the site (the transition from the upper branch of the conveyor to the lower.

FIG. 1 shows a schematic installation in longitudinal section; in fig. 2 - saling in the plan; in fig. 3 - a general view of the form in the closed state; in fig. 4 - view along arrow A | fig. 3

The installation contains a vertical conveyor 1, on which forms 2 are mounted for moving and drying the tubes 3, and a drying chamber 4 with convective heating, as well as a positioned conveyor 1.

Form 2 is made in the form of two pivotally connected semi-cylinders: the top 5 and the bottom 6.

The inner part of the semi-cylinders 5 and 6 has liners 7 of moisture-absorbing material.

The upper half-cylinder 5 of form 2 is made with levers 8 overlapping, and the lower 6 - with three-sided prism 9 for fixing the position of semi-cylinders when blowing the forms. A roller anchor 10 is installed under the upper chain of the conveyor. The installation is equipped with a shock absorber of the CPU on another table 11.

Conveyor 1 has a limit switch 12 and is equipped with 1 directional 13 channels for moving the molds 2 in the drying chamber 4. The installation | works as follows.

A clamp on the limit switch 12 stops the conveyor 1 at the time of laying the freshly pressed tube 3.

A freshly shaped perforated ceramic tube 3 is placed in the lower half-cylinder 6 of shape 2.

When the conveyor 1 moves, the lever 8 interacts with the roller anchor 10 and the form 2 is closed by the upper semi-cylinder 5. Upon further movement of the conveyor 1 together with the closed form 2, aiKTHBHoft moisture is taken from the surface of the freshly formed tube 3 with the liner 7.

When switching from the top 1 of the co-flayer 1 to the bottom (Nyu form 2 under the action of its own weight opens, and the tube 3 is placed on the damping table 11 (initial (The position of the tube 3 on the table 11 is shown dotted)).

The empty open forms 2 move inside the drying chamber 4 with a coherent heating, where the top 5 and the bottom occur: 6 half-cylinders of the form 2 and the removal of absorbed moisture from the inserts 7. Then the cycle repeats.

Subject invention

Drying, mainly for piece goods, containing forms moved by means of a vertically closed conveyor, opened (closed) during loading and unloading operations, and heat-blowing equipment for blowing empty forms, which is different from those, in order to improve the quality of drying, the form consists of articulated horizontal semi-cylinders with moisture-absorbing liners inside and the upper semi-cylinder is equipped with a lever that interacts with the roller anchor to close the we, and the bottom - of the triangular prism to fix the half cylinders with blowing polozhe1NIYa forms disclosed under the action of the actual weight "and the transition region from the upper branches of the conveyor bottom.
