Description

Technical Field

[0001] This utility model relates to the field of petroleum coke processing equipment, specifically a petroleum coke calcining kiln. Background Technology

[0002] The black solid coke produced by cracking and coking petroleum vacuum residue at 500-550℃ in a coking unit is generally considered to be an amorphous carbon body, or a highly aromatic polymeric carbide containing needle-like or granular structures of tiny graphite crystals.

[0003] When petroleum coke is calcined, combustion air needs to be introduced and waste gas needs to be discharged. During the discharge of waste gas, a large amount of heat is carried away, resulting in energy waste. At the same time, when new raw materials are injected into the calcining furnace, the internal temperature of the calcining furnace can drop rapidly because the raw materials are at room temperature. It takes time to reach the calcination temperature, which reduces the calcination efficiency. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a petroleum coke calcining kiln to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petroleum coke calcining kiln, comprising a calcining furnace, a preheating box fixedly installed on one side of the calcining furnace, an exhaust pipe fixedly installed at the top of the calcining furnace, a pump body fixedly installed at the top of the preheating box, the input end of the pump body extending into the preheating box through a pipe, a first pipe fixedly installed at the output end of the pump body, a second pipe fixedly installed inside the preheating box, a spiral pipe fixedly installed between the first pipe and the second pipe, a groove formed at the bottom of the inner side of the preheating box, a motor fixedly installed on one side inside the groove, an auger fixedly installed at the output end of the motor, and one side of the groove communicating with the outside of the preheating box. When in use, the raw materials to be calcined are stored inside the preheating box. When the exhaust pipe is venting, the pump is started, pumping the cooling oil inside the preheating box into the first pipe, and then returning it to the preheating box through the spiral pipe and the second pipe. The heat from the exhaust gas is carried into the preheating box to heat the raw materials inside. When the raw materials are taken out, the motor is started, and the motor drives the auger to rotate, so that the raw materials that have entered the tank are discharged to the outside of the preheating box. By preheating the raw materials, the rapid cooling of the calcining furnace when the raw materials enter the furnace is prevented, thus ensuring calcination efficiency. At the same time, the raw materials at the bottom of the preheating box are taken first, because the raw materials at the bottom of the preheating box are preheated more thoroughly.

[0006] Preferably, the calcining furnace further includes a feeding pipe, a control valve, and an injection pipe. The feeding pipe is embedded and fixed at the top of the calcining furnace for easy replenishment of raw materials. The control valve is embedded and fixed on one side of the calcining furnace, and one side of the injection pipe is fixed to the control valve. During use, air is replenished into the calcining furnace through the injection pipe, and the air intake is controlled by the control valve. At the same time, raw materials are replenished into the calcining furnace through the feeding pipe.

[0007] Preferably, a maintenance plate is installed on one side of the calcining furnace to facilitate disassembly and maintenance of the calcining furnace.

[0008] Preferably, the preheating box is filled with cooling oil.

[0009] Preferably, the first pipe is fixedly inserted into the exhaust pipe.

[0010] Preferably, one side of the second pipe is fixedly inserted into the interior of the exhaust pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, the raw materials to be calcined are stored inside the preheating box. When the exhaust pipe is venting, the pump is started, pumping the cooling oil inside the preheating box into the first pipe, and then returning it to the preheating box through the spiral pipe and the second pipe. The heat from the exhaust gas is carried into the preheating box to heat the raw materials inside. When the raw materials are taken out, the motor is started, and the motor drives the auger to rotate, so that the raw materials that have entered the tank are discharged to the outside of the preheating box. By preheating the raw materials, the rapid cooling of the calcining furnace when the raw materials enter the furnace is prevented, thus ensuring calcination efficiency. At the same time, the raw materials at the bottom of the preheating box are taken out first, because the raw materials at the bottom of the preheating box are preheated more thoroughly.

[0020] Working principle: During use, the raw materials to be calcined are stored inside the preheating box 6. When the exhaust pipe 5 exhausts, the pump body 10 is started. The pump body 10 pumps the cooling oil inside the preheating box 6 into the first pipe 9, and then returns it to the preheating box 6 through the spiral pipe 11 and the second pipe 8. It also carries the heat from the exhaust gas into the preheating box 6 to heat the raw materials inside the preheating box 6. When the raw materials are taken out, the motor 12 is started. The motor 12 drives the auger 13 to rotate, so that the raw materials that have entered the tank 14 are discharged to the outside of the preheating box 6. By preheating the raw materials, the rapid cooling of the calcining furnace 1 when the raw materials enter the furnace is prevented, thus ensuring calcination efficiency. At the same time, when taking out the raw materials, the raw materials at the bottom of the preheating box 6 are taken first, because the raw materials at the bottom of the preheating box 6 are preheated more thoroughly.
