Connecting device capable of reducing stress of heating pipes of roasting furnace

Abstract

The invention discloses a connecting device capable of reducing stress of heating pipes of a roasting furnace. The device comprises an outer furnace barrel in which an inner furnace barrel is arranged, wherein a first heating pipe, a second heating pipe, a third heating pipe and a fourth heating pipe are correspondingly arranged around the inner furnace barrel and are all connected through arc-shaped bends; one end of the first heating pipe and one end of the third heating pipe are provided with positioning plates; a damping device is arranged at one end of each positioning plate; two fixing rods are fixed to the sidewall of one inner end of the outer furnace barrel; and a mounting plate is fixed to the lower end of each fixing rod. According to the device, the problem that two sections ofexisting heating pipes at each layer are connected through an annular pipe which leads to high stress can be solved; the arc-shaped bends are used for connecting, so that the stress applied to the heating pipes of the roasting furnace is reduced, and welding seams of the heating pipes are prevented from tearing, and as a result, the running time of the heating pipes of the roasting furnace can beincreased; and the convenience of use is ensured.

Description

technical field [0001] The invention relates to the technical field of combined soda ash, in particular to a connection device for reducing the stress of a heating tube of a calciner. Background technique [0002] The steam calciner is an important equipment for the production of soda ash. The steam calciner is composed of a feed screw, a furnace head part, a furnace body part, a steam inlet shaft and a transmission device. High-temperature steam is introduced into the furnace body through the steam inlet shaft. Let the materials entering the furnace head and furnace body from the feed port react to produce soda ash, and then the finished product of soda ash is discharged through the furnace head, and the transmission device plays the role of rotating the furnace body, but the current calciner is unstable and may vibrate It will affect the heating tube and cause problems with the heating tube. [0003] There is a problem in the existing heating tube connection method of the...

[0002] The steam calciner is an important equipment for the production of soda ash. The steam calciner is composed of a feed screw, a furnace head part, a furnace body part, a steam inlet shaft and a transmission device. High-temperature steam is introduced into the furnace body through the steam inlet shaft. Let the materials entering the furnace head and furnace body from the feed port react to produce soda ash, and then the finished product of soda ash is discharged through the furnace head, and the transmission device plays the role of rotating the furnace body, but the current calciner is unstable and may vibrate It will affect the heating tube and cause problems with the heating tube

[0003] There is a problem in the existing heating tube connection method of the calciner. The two sections of the heating tube in each layer are connected by an annular tube. At the same time, a horseshoe-shaped joint is separated from the lower layer to connect the annular tube of the heating tube in the upper layer. The stress at the horseshoe-shaped interface of the heating tube is large. , often cause the welding seam of the heating tube to tear, burst the tube, and affect the operation of the calciner. Therefore, we propose a connection device that reduces the stress of the heating tube of the calciner to solve the above problems
