Description

Waste salt melting furnace capable of removing slag in operation

Technical Field

The invention relates to the technical field of waste salt treatment equipment, in particular to a waste salt melting furnace capable of removing slag in operation.

Background

The waste salt generally refers to various byproduct industrial salts generated in chemical production, the amount of the various byproduct industrial salts is increased along with the rapid development of national economy, the current waste salt treatment mode is generally to convey the waste salt to a solid waste treatment center for treatment, but because the treatment cost of the solid waste treatment center is higher and the medium and small enterprises are difficult to bear, the solid waste treatment center can be stacked, or directly buried, which on the one hand occupies the land and causes great pollution risk to the environment, when the anti-corrosion and anti-seepage treatment layer in the landfill site leaks, impurities such as organic matters in the waste salt and the like leak out, causes pollution to the surrounding soil, underground water, farmlands and the like, and on the other hand, wastes resources greatly, because industrial salt is a basic raw material in the chemical field and is also an important strategic resource in China, how to recover waste salt is an important research direction at present.

Therefore, in view of the above problems, the inventor has studied a melting furnace for recovering waste salt, which melts waste salt at a high temperature, burns and gasifies organic matters therein to be discharged, and precipitates refractory substances, and cools and crystallizes a solution flowing out from a furnace body to obtain recovered industrial salt.

Disclosure of Invention

The invention provides the waste salt melting furnace capable of removing slag in operation, so that the melting furnace does not need to be stopped for slag removal in the working process, and the continuity of the operation is improved.

In order to achieve the purpose, the technical scheme of the invention is as follows:

can be in the waste salt melting furnace of slagging-off in the operation, the induction cooker comprises a cooker bod, the furnace body includes furnace roof, oven and stove bottom, is equipped with a plurality of flame guns on furnace roof and the oven, the stove bottom is slope form, is equipped with the feedstock channel who is located the stove bottom high-end on the furnace roof, is equipped with the leakage fluid dram that is close to the stove bottom low side on the oven, be equipped with in the furnace body and remove sediment frame and actuating mechanism, be equipped with row cinder notch on the oven that the furnace body is close to feedstock channel one side, row cinder notch surpasss the height of liquid level in the furnace body, actuating mechanism drives and removes the sediment frame and removes to row cinder notch removal, removes the bottom and the stove bottom laminating of sediment frame.

The technical principle and the effect of the technical scheme are as follows:

the waste salt particles are sent into the furnace body through the feeding channel and are quickly melted under the ignition of each flame gun in the furnace body to form molten liquid, organic matters contained in the molten liquid are burnt at high temperature and gasified to be discharged, and the molten waste salt liquid flows to a liquid discharge port along the furnace bottom. When the melting furnace begins the operation, the slagging-off frame is located the least significant end at the bottom of the stove, be located the below of leakage fluid dram promptly, when needs slagging-off, actuating mechanism pulls the slagging-off frame and removes to row cinder notch one side, at the slagging-off frame removal in-process, the difficult thing that melts of deposit at the bottom of the stove enters into the slagging-off frame, when the slagging-off frame is close to row cinder notch, the difficult thing that melts in the slagging-off frame is discharged the furnace body through row cinder notch, consequently, this in-process furnace body need not stop work at row sediment, just can accomplish row sediment, and because row cinder notch will be higher than the liquid level of waste salt solution in the furnace body, consequently, the problem of solution seepage can not take place.

Furthermore, the two ends of the deslagging frame are respectively connected with idler wheels in a rotating mode, a guide rail is arranged in the furnace body, the idler wheels are connected to the guide rail in a rolling mode, and the high end of the guide rail is close to the deslagging port.

Has the advantages that: the roller is matched with the guide rail, so that the slag removing frame can ascend and descend and can be kept on the guide rail and cannot move randomly in the furnace body.

Furthermore, the outer wall of the furnace body is provided with a slag discharging door which can be opened and closed and seals the slag discharging port.

Has the advantages that: therefore, the loss of heat in the furnace body can be reduced, and the safety of the external operation environment is also ensured.

Further, actuating mechanism includes motor, reduction gear and two sets of guide pulley mechanisms, the output shaft and the retarder connection of motor, guide pulley structure includes pull wire, fixed pulley and reel, and the fixed pulley among two sets of guide pulley mechanisms sets up respectively in the both sides of row cinder notch, and pull wire one end is fixed on the lateral wall that the frame of removing the cinder notch is close to gyro wheel one side, and the other end is fixed on the reel, and the pull wire leads through the fixed pulley, and coaxial fixed has the winding post on the reel, the output shaft coaxial coupling of winding post and reduction gear.

Has the advantages that: the winding wheel is driven to rotate at a low speed through the motor and the speed reducer so as to realize the winding and unwinding of the traction line on the winding wheel, and further realize the back and forth movement of the deslagging frame in the furnace body.

Further, all be equipped with the fixed pulley on the inside and outside wall of furnace body, set up on the oven and supply the wire hole of pull wire exhaust, motor, reduction gear and reel all are located the outside of furnace body.

Has the advantages that: the fixed pulley is mainly used for guiding the traction line, so that the abrasion between the traction line and the furnace wall is reduced.

Further, the inclination angle of the furnace bottom is 5-8 degrees.

Has the advantages that: the too big angle of stove bottom slope can make waste salt solution flow to the leakage fluid dram fast, and the organic matter that contains in it does not reach to obtain abundant burning, and the angle undersize of slope, and waste salt solution's flow velocity is too slow, can make the efficiency of melting furnace low excessively, therefore the inclination in this scheme of adoption can overcome above-mentioned problem.

Furthermore, the furnace top is also in a slope shape and is arranged in parallel with the furnace bottom.

Has the advantages that: therefore, the distance from the flame gun positioned on the furnace top to the furnace bottom can be reduced, and the combustion of organic matters in the waste salt is more sufficient.
