Description

A rotary feeding sealing device

technical field

The utility model relates to a high-temperature-resistant rotary feeding sealing device, which can be used in the kiln chamber feeding field of active lime shaft kiln and other feeding fields.

Background technique

The rotary feeding sealing device of the active lime shaft kiln is generally in the form of single bell feeding, double feeding bell, single layer rotary distributor and so on. These forms of feeding sealing devices need to be improved in terms of feeding uniformity, durability, and sealing performance. The disadvantages are as follows:

1) The hopper relies on multiple travel switches to discharge materials at multiple points, the structure is complex, the cloth distribution effect is not good, and it is easy to cause material segregation;

2) It is very inconvenient and dangerous to enter the kiln chamber to replace the sealing element;

3) The noise of the hopper is very loud, and the wear of the hopper is also serious, which is not conducive to environmental protection;

4) There is a lot of dust leakage and the production environment is poor;

5) Single-layer sealing structure, the sealing effect is not good, and the sealing is not reliable;

6) Sometimes the temperature of the kiln feeding port is high, which damages the sealing ring; air leakage and ash leakage are serious.

In the past ten years, with the development of scale, serialization and industrialization of active lime shaft kilns, the design capability of shaft kilns has been continuously increasing, and a kiln feeding and sealing device with independent intellectual property rights and reasonable comprehensive indicators is required. Meet the needs of serialization and large-scale development of shaft kilns, and meet the needs of the domestic lime industry.

Contents of the invention

The purpose of the utility model is to provide a rotary feeding sealing device, which has good feeding uniformity, good sealing effect, replaceable sealing parts of the kiln mouth, and reliable structure.

In order to achieve the above object, the utility model is realized through the following technical solutions:

A rotary feeding sealing device, including a hopper, a sealing cone, and an oil cylinder, characterized in that the hopper includes two parts: an upper rotating hopper and a lower fixed hopper, the upper rotating hopper is driven to rotate by a transmission mechanism, and its speed is adjustable; The discharge port of the upper rotating hopper is set away from the center of the fixed hopper; the upper rotating hopper is connected with the lower fixed hopper by a telescopic sealing structure.

The contact part between the sealing cone and the lower fixed hopper has an arc-shaped structure and is sealed by a sealing ring; the sealing ring is fixed by a sealing outer frame structure.

Both the sealing cone and the sealing ring are provided with cooling air inlets.

The upper rotating hopper and the lower fixed hopper are provided with rubber liners inside.

Compared with the prior art, the beneficial effects of the utility model are:

1) The speed of the upper rotating hopper can be continuously controlled to ensure uniform feeding process, prevent segregation, and have good manufacturability.

2) The lower hopper is fixed on the top of the kiln chamber and can be stretched, so that it is convenient to disassemble and replace the seals outside the kiln.

3) Rubber liners are added to the upper rotating hopper and the lower fixed hopper to prevent wear and noise caused by materials hitting the side wall of the hopper, which is beneficial to environmental protection.

4) The upper rotary hopper is covered with a cover, and the telescopic seal is used between the upper rotary hopper and the lower fixed hopper. The overall seal is good, and the dust generated during the feeding process does not leak out, which is environmentally friendly.

5) The sealing cone of the kiln chamber adopts multiple seals of arc-shaped cones and sealing rings, and the sealing is more reliable, ensuring that the sealing effect is foolproof.

6) Cooling air is used to cool the sealing cone and sealing ring of the kiln mouth at the feeding port of the kiln to ensure the service life and sealing effect of the sealing device.

Detailed ways

The structure of the rotary feeding sealing device will be described in detail below through specific embodiments.

See Figure 1 and Figure 2, a rotary feeding sealing device, including an upper rotary hopper 1, a lower fixed hopper 2, a sealing cone 5, and an oil cylinder 3. The upper rotary hopper 1 and the lower fixed hopper 2 are connected by a telescopic sealing structure 7 ; The upper rotating hopper is driven to rotate through the transmission mechanism 8, and its speed is adjustable; The upper rotating hopper 1 and the lower fixed hopper 2 are provided with rubber liners.

The contact part of the sealing cone 5 and the lower fixed hopper 2 is an arc-shaped structure (see FIG. 3 ), which has better sealing performance, and uses a sealing ring 9 for double sealing, and the sealing ring 9 is fixed by the sealing outer frame structure 4 . Both the sealing cone 5 and the sealing ring 9 are provided with cooling air inlets. The cooling air can be fed into the cooling air inlet to adjust the pressure of the kiln mouth and also play a cooling role. The overall structure is reliable, the dust sealing effect is good, and the installation and disassembly are convenient.

The working process of this device is: the upper rotating hopper 1 is used to evenly distribute the incoming materials to the lower fixed hopper 2 through rotation, the sealed outer frame 4 and the sealing cone 5 separate the materials from the kiln chamber, and the oil cylinder is lifted when feeding is required 3. Drop and open the bottom of the lower fixed hopper 2, and feed materials into the kiln chamber. After feeding, the lifting cylinder 3 lifts the sealing cone 5 and recloses the discharge port of the fixed hopper. The telescopic sealing structure 7 can ensure that the dust in the feeding process does not leak out, and can be lifted to replace and overhaul the sealing ring.
