background
Melting, blowing and refining, which are carried out separately, are the basic steps and procedures for the industrial production of copper. After the smelting furnace, the converting furnace and the refining furnace complete respective reaction processes, molten high-temperature copper matte needs to be transported and injected into the next-stage smelting furnace for further reaction and purification, and anode copper matte obtained by the refining furnace needs to be transported to a casting trough for casting into a copper ingot. In the prior art, copper matte transportation is finished through copper-clad bearing transportation. In order to shorten the smelting process, reduce heat loss and reduce the influence of open copper cladding on the surrounding environment, part of enterprises adopt the closed diversion trench to finish copper matte conveying, and a good production effect is obtained. The following problems and deficiencies remain, mainly: first, the transport pipeline is a long and thin uninterrupted chute, and has large overall heat dissipation area, long exposure time and large heat loss. Secondly, the viscosity of the copper matte is increased due to the loss of heat energy until the flow rate is reduced or even blocked. And thirdly, the smelting furnace, the converting furnace and the refining furnace are not linearly arranged one to one, and the refining furnace needs to feed quantitatively the reaction process in a stable state, so that the converting furnace needs to alternately and discontinuously convey two to two through the Y-shaped diversion trenches, and the diversion trenches in the intermittent period are naturally cooled. Aiming at the problems, the diversion trench is subjected to heat insulation and preservation and is covered to reduce heat loss, and a burner is arranged on the trench cover to heat and preheat the flow path and cool the diversion trench. But still the people are hard to feel at will, the heat energy and the energy are wasted, and the dissipated heat energy pollutes the working environment. The selection and operation of the heating process increases the labor intensity of the operator.
Disclosure of Invention
The invention aims to provide a heat-radiation-reflecting copper matte closed heat-insulating diversion trench which is simple in structure, easy to manufacture and more excellent in heat-insulating effect, aiming at the problems and the defects existing in the way of transporting copper matte through the diversion trench.
The purpose of the invention is realized by the following technical scheme:
The utility model provides a copper matte of anti-heat radiation seals heat preservation guiding gutter, including the cell holder chassis, the capping, the arc lining lid, two slotted shafts, U type resistant firebrick, support protruding leg, the chute, nozzle and anti-heat radiation coating, characterized by scribbles at the inner face of cell holder chassis, capping and arc lining lid and hangs and use fire-resistant fritting material as the masterbatch, use the anti-heat radiation coating of filling fast grain as additive combination, utilize the spacious space that forms between the protruding leg of support of U type resistant firebrick and cell holder chassis, utilize the spacious space between capping and arc lining lid and chute, form anti-heat radiation isolation region, utilize the physical characteristic of superstrong anti-radiation, low thermal conductivity and high temperature resistance of filling fast grain, prevent high temperature copper matte in the chute to lose in the heat energy of transportation process.
The heat-radiation-reflecting copper matte closed heat-insulating diversion trench is characterized in that a burner arranged on the longitudinal central line of a trench cover is reserved and used for starting the diversion trench, converting the copper matte conveying direction and preheating before intermittent reuse.
The heat-radiation-reflecting copper matte closed heat-insulation diversion trench is characterized in that two sides of a trench cover are respectively provided with a double-slotted shaft, so that the trench cover can be conveniently lifted or moved away from the two sides, the operation condition of the copper matte can be observed, and the diversion trench can be maintained.
Compared with the prior art, the invention has the characteristics of simple structure, easy manufacture and excellent heat preservation effect, and simultaneously has the following advantages:
1. The engorgement particles are used as the heat-insulation and heat-preservation external coating additive for the spacecraft to re-enter the atmosphere and safely pass the black barrier period in the United states space administration, and are widely noticed and utilized once being opened, and space is created for the heat radiation reflecting performance of the engorgement particles by improving the morphological structure of the U-shaped refractory bricks. The arc-shaped lining cover is additionally arranged on the groove cover, and the upper part of the guide groove, which is weak in heat preservation, is provided with double heat insulation insurance, so that the relative constant-temperature transportation of copper matte in the guide groove is ensured.
2. two sides of the groove cover are provided with double slotted shafts, so that the two sides of the groove cover can be conveniently lifted and observed, and the guide groove can be conveniently moved away for maintenance. The work is convenient, and the labor intensity is reduced.
3. And the heat preservation and heat insulation performance of the diversion trench is enhanced. The smoothness of the copper matte transportation process is ensured. And the second is to keep the temperature of the copper matte input into the converting furnace or the refining furnace, so that the heating process and the heat energy input required by further reaction are reduced, the smelting period is shortened, and the energy is saved.
4. The heat energy loss in the copper matte transportation process is reduced, the heat pollution of the surrounding environment is reduced, and the working environment of operators is improved.
