Description

The door offered for confectionery and baking ovens consists of several sections hinged on a horizontal axis. Each section is made with the possibility of mixing it along the axis of the hinge and is provided with a pin that fits into the recess of the ring, which is fastened to the axis of the hinge and is intended to fix the section in the open position.

In order to be able to change the size of the opening of each individual section by simulating a recess of the retaining ring, the latter is made pivoting and locking on the hinge axis.

FIG. 1 shows a cross-section of the proposed dvsr |; n; in fig. 2 is a front view of it.

The proposed door refers to the type of visor, i.e., turning on a horizontal hinge.

The door consists of a series of sections, i.e., individual doors 4, 5, 6, 7 and 8, which open separately and shut off; the front opening of the baking chamber for the full width of the hearth.

The height of the door is 200 mm and is selected depending on the angle of elevation of the slide and the hearth, so that working on planting and dredging the bread, having opened the door to the desired angle, can see the corresponding part of the hearth.

The width of each section is selected depending on the total width of the hearth and the number of sections. Based on practical working conditions, the width of an individual section can vary from J75 to 425 mm.

Each door section is loosely seated on a common horizontal axis for all sections and can rotate around this axis so that it can move along it. On the hinge of each section there is a pin}. A locking ring 2 is fitted on the horizontal axis with a notch for pin 1.

No. 62706-2-Setting the ring 2 to any position with the help of the bolt 3, you can set the door angle to the desired value, which is a very important condition for operation. ..

Owing to such a device, the one working in the furnace for opening the door takes the left hand by the handle 9 of one of the sections and raises the section up, slightly pressing it to the left. The section will be raised until the pin 7 reaches the notch in the ring 2. In this section, the pressure will be moved 10 lsh to the left under the action of the pin, the pin / zastet into the notch of the ring 2 and the section will lock in the open position. The door is closed in the reverse order:. T .-- in order to achieve the necessary and sufficient heat tightness, the joints of each section are covered with overlays rotating freely on the same horizontal axis. Each pad for a snug fit to the surface of the section is seated on its arm with a tolerance enabling it to freely overlap the section.

When lifting any section of the lining, the sections available on both sides also lift to open the necessary part of the hearth.

Across the width of the baking chamber opening, a scallop is welded to the door frame, sealing the gaps between the frame and the sections.

The sections are made of 2.5 mm thick sheet steel with flanging edges for rigidity. The linings are made of iron, J, 5 mm thick, also flared.

Sections, as well as overlays should be made on one pattern and processed exactly in size.

Claims (2)

1. A door for pastry and bakery ovens composed of several sections pivotally mounted on a horizontal axis, wherein each section is movable along the axis of the hinge and provided with a tongue that fits into the cutout of the ring fixed on the axis of the hinge open position. 2. The form of the door according to item I, is from the fact that, in order to allow the cut to move to change the size of the opening sections, the ring is made rotatable and locks on the hinge axis.
