Description

The device for relieving blasting at the bottom of the tank furnace

technical field

The invention relates to a device for solving common faults in the production process, in particular to a device for relieving blasting at the bottom of a tank furnace for the production of aluminum anodes, cathodes, electrodes and carbon graphitized materials in the carbon industry.

Background technique

Due to the volatile matter carried by the combustion material itself in the fire channel, the tank type calciner indirectly heats the material in the material tank, which not only saves energy, has less carbon loss, and is stable in production, so it is chosen by the majority of owners as the product calciner equipment. use.

However, in the production process of the tank furnace, there is a big disadvantage-the blasting at the bottom of the furnace. Furnace bottom blasting mainly refers to the explosion reaction after the escaping volatile matter contacts with the air in the lower part of the crusher. The main reason for the explosion is that the concentration of combustibles gradually increases to the limit of explosive concentration and the air in the receiving hopper is not circulated. Since the receiving hopper cannot be completely sealed, it is filled with air. The volatile matter of the reaction here mainly comes from two aspects: first, the material escapes a large amount of volatile matter after being heated on the upper part of the material tank, and a small part of the volatile matter will be wrapped by petroleum coke dust particles until the bottom of the furnace body; Second, part of the volatile matter is only precipitated at the calcination zone of the furnace body, and will also be brought to the bottom position as the material moves downward. the

When the blasting phenomenon is more serious, it mainly damages the equipment such as the furnace body and the crushing machine, causing the equipment to be shut down for maintenance. Therefore, inventing a device for solving the blasting of the furnace body can effectively prevent the above-mentioned production drawbacks.

Contents of the invention

The present invention proposes a device for alleviating blasting at the bottom of a tank furnace to solve the above problems, with the purpose of avoiding blasting in the actual production process, ensuring stable operation of equipment, and improving production efficiency.

In order to achieve the above-mentioned purpose, the device for alleviating blasting at the bottom of the pot furnace according to the present invention is composed of the following structures: a horizontal horizontal circular tube connected with the receiving hopper, a vertical collection circular tube connected with the horizontal horizontal circular tube, and the vertical collection circular tube passes through The vertical circular pipe is connected with the horizontal collecting circular pipe, and the horizontal collecting circular pipe is connected with the main pipe of the dust collector.

Each receiving hopper is connected with a horizontal horizontal circular pipe, and the horizontal horizontal circular pipes connected to the adjacent receiving hoppers are connected with the vertical circular pipes through the vertical collecting circular pipes.

The horizontal horizontal circular pipe is arranged at the side middle and lower part of the vertical ground of the receiving hopper.

Flanges are arranged on the vertical round pipes on both sides of the horizontal collection round pipe.

There is a dust removal point on the vibrating conveyor, and the dust removal pipe is connected with the dust removal main pipe.

Advantageous effect of the present invention:

The invention can incorporate the air in the receiving hopper into the dust collection system of the vibrating conveyor to make the air circulate, effectively alleviate the phenomenon of blasting at the bottom of the pot furnace during the calcination production process, ensure the safe and continuous operation of the equipment, and improve the operation rate and efficiency of the equipment. product productivity.

Detailed ways

The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.

As shown in Figure 1, the device for alleviating blasting at the bottom of the pot furnace of the present invention is composed of the following structures: a horizontal horizontal circular tube 3 communicated with the receiving hopper 1, a vertical collection circular tube 4 connected with the horizontal horizontal circular tube 3, a vertical The straight collection round pipe 4 is connected with the horizontal collection round pipe 7 through the vertical round pipe 6, and the horizontal collection round pipe 7 is connected with the dust removal main pipe 8.

Each receiving hopper 1 is connected with a horizontal horizontal circular tube 3 , and the horizontal horizontal circular tubes 3 connected to adjacent receiving hoppers 1 are connected with the vertical circular tube 6 through the vertical collection circular tube 4 .

The horizontal horizontal circular pipe 3 is arranged at the middle and lower part of the side of the receiving hopper 1 in the direction of the vertical vibrating conveyor 2 .

The vertical tubes 6 on both sides of the horizontal collection tube 7 are provided with flanges 5 .

The vibrating conveyor 2 is provided with a dust removal point, and the dust removal pipe is connected with the main pipe 8 .

The air entering from the bottom of the receiving hopper 1 forms a flow path under the negative pressure generated by the induced draft fan after the dust collector, and enters the dust removal main pipe 8 through the horizontal horizontal circular pipe 3, the vertical circular pipe 6, and the horizontal collecting circular pipe 7 successively. The dust collection system is discharged into the atmosphere. Two adjacent groups of retort furnaces use a set of pipes, and one set corresponds to one or more receiving hoppers. One receiving hopper only needs one horizontal and horizontal circular tube. The present embodiment is two adjacent receiving hoppers.
