Problems solved by technology

With the progress of industries in various countries in the world, furnaces are also developing towards large-scale, high-efficiency and long-life. Lining refractory materials have also undergone major changes. Long-life new, high-efficiency refractory materials, and better lining protection and energy-saving coatings have gradually been applied, and the energy efficiency and service life of furnaces have gradually improved. Many low-level conditions, and the large-section drying chamber is a brick-concrete structure, it is very difficult to upgrade and increase production, and the cost is extremely high. In view of this situation, an old kiln raising device and its raising method are proposed

Embodiment 1

[0039] A method for raising an old furnace raising device includes the following steps:

[0040] Step 1: Use a single 50t mechanical jack to fix on the jack platform plate 13, use the walking wheel 2 to push the device into the kiln room, and connect multiple devices to reach the length of the kiln room.

[0041] Step 2: Cut and separate the reinforced concrete structural column of the kiln body from the ring beam and the roof, and chisel out the ends of the steel bars. Jacks 3 and 4 will lift the kiln roof as a whole.

[0042] Step 3: After the kiln roof is fully jacked up and re-welded, high-grade concrete is poured, and the cast-in-situ beams and slabs of the kiln roof are cut in sections at intervals to leave the ends of the steel bars, and the ends of the steel bars are raised to the required sections by lifting mechanical devices. height.

[0043] Step 4: Masonry walls, welding steel bars, pouring high-grade concrete, and repairing the main and branch pipelines after all the kil...

Embodiment 2

[0045] Using a single 50t mechanical jack, 20 sets of synchronous work to make a jacking mechanism, cut the kiln body reinforced concrete structural column, ring beam and roof, cut apart, chisel out the end of the steel bar, re-weld after jacking, and cast high Marked concrete. The cast-in-situ beams and slabs of the kiln roof are cut into sections at intervals of 7 meters to leave the ends of the steel bars, and the ends are raised to the required height by lifting mechanical devices. The walls are built, steel bars are welded, and high-grade concrete is poured. After all the kiln body has been raised, repair the main and branch pipelines.

Abstract

The invention discloses an old furnace rising device and a rising method thereof. The device comprises an equipment platform, steel structure vertical plates which are distributed in an array manner are arranged on the equipment platform, the steel structure vertical plates directly form an open groove, jack platform plates are arranged on the inner sides of the steel structure vertical plates, the lower end of the jack platform plate on one side is provided with a first inclined supporting plate, the lower end of the jack platform plate on the other side is provided with a second inclined supporting plate, walking wheels distributed in an array manner are arranged on the lower end of the equipment platform, jacks distributed in an array manner are arranged on each jack platform plate, theupper ends of the jacks are jointly provided with jacking platforms, buffers distributed in an array manner are arranged on the jacking platforms, the buffers are arranged over the jacks, wing platesdistributed in an array manner are arranged on two sides of the jacking platforms, and the wing plates are arranged in the open groove. The device is easy to manufacture, mounting and dismounting areconvenient, the technical need is low in difficulty, manufacturing cost is low, operation of a worker is facilitated, production efficiency of an old furnace is improved, the yielding capacity of theold furnace can be improved, and use of facilities can be improved.

Description

Technical field [0001] The invention relates to the field of building materials production facilities, in particular to an old furnace raising device and a raising method thereof. Background technique [0002] Kilns can be divided into ceramic kilns, cement kilns, glass kilns, enamel kilns, etc. according to the types of calcined materials. The former can be divided into continuous kiln (tunnel kiln), semi-continuous kiln and intermittent kiln according to the operation method. Generally, the fuel of large-scale kilns is mostly heavy oil, light diesel or coal gas, and natural gas. The kiln usually consists of kiln room, combustion equipment and ventilation equipment. Conveying equipment and other four parts, the electric kiln mostly uses electric furnace wire, silicon carbide rod or molybdenum disilicide as heating elements. Its structure is relatively simple and easy to operate. In addition, there are a variety of atmosphere kilns, electric porcelain kilns, etc. Due to the spec...
