Description

Technical Field

[0001] The invention relates to the technical field of industrial equipment, and in particular to a rotary automatic unloading and air outlet device. Background Art

[0002] Oily sludge is an oily solid waste generated during the oil extraction, transportation, refining and oily wastewater treatment. The oil content in the sludge is generally 10-15% and the water content is 40-90%. Oily sludge contains a large amount of odorous toxic substances such as benzene, phenols, anthracene, pyrene, etc. If it is discharged directly without treatment, it will not only occupy a large amount of arable land, but also pollute the surrounding soil, water and air. The sludge also contains a large amount of pathogens, parasites (eggs), heavy metals such as copper, zinc, chromium, mercury, salts, and toxic and harmful substances that are difficult to degrade, such as polychlorinated biphenyls, dioxins, and radionuclides. At present, oily sludge sand has been listed as hazardous waste by the state.

[0003] In the HSEF-400A oil sludge environmental treatment system, a large amount of combustible gas will be continuously generated during the treatment of the oil sludge in the rotating furnace chamber. These gases must be transported to the outside of the furnace chamber for liquefaction and storage in a timely manner, while ensuring the airtight state of the furnace chamber; after the oil sludge is treated, the remaining solid phase materials need to be quickly unloaded in a short time. Both gas exhaust and unloading are achieved under the condition that the furnace chamber is constantly rotating and requires sealing, so how to ensure that the two do not interfere with each other is the problem to be solved. Summary of the invention

[0004] In view of the above-mentioned defect of interference between gas outlet and discharge, the object of the present invention is to provide a rotary automatic unloading and gas outlet device. While ensuring the airtightness of the interior of the rotary furnace chamber, the unloading and gas outlet are centrally arranged, and the gas outlet pipe is forked and bypasses the automatic unloader and then intersects, so that the unloading and gas outlet do not interfere with each other.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a rotary automatic unloading and gas outlet device, comprising a rotary furnace, a discharge port is arranged at one end of the rotary furnace, an automatic discharger is detachably and movably connected to the discharge port, the rotary furnace is connected to a forked gas outlet pipe assembly, the forked gas outlet pipe assembly comprises at least two gas outlet pipes located in the rotary furnace, one end of each gas outlet pipe is connected to the rotary furnace, and the other end passes through the rotary furnace and bypasses the automatic discharger before intersecting with a gas outlet intersection pipe, a sealed exhaust pipe is movably sleeved on the gas outlet intersection pipe, a sealing ring is arranged at the connection between the gas outlet intersection pipe and the sealed exhaust pipe, the gas outlet intersection pipe is connected to the sealed exhaust pipe, and the rotary furnace, the automatic discharger and the gas outlet intersection pipe are coaxially arranged.

[0006] Working principle: When the sludge is processed in the rotary furnace, the rotary furnace rotates continuously, the automatic discharger and the gas outlet intersection pipe rotate with the rotary furnace, and the material rolls continuously with the rotary furnace. After reaching the cracking temperature, a large amount of combustible gas is released. The combustible gas enters the gas outlet intersection pipe from the gas outlet pipe, and is sent to the cooling device through the gas outlet intersection pipe and the sealed exhaust pipe to be cooled and liquefied for storage. After the sludge is processed, no more combustible gas is generated, and the remaining solid material comes out of the discharge port and is automatically discharged under the action of the automatic discharger; the sealed exhaust pipe remains relatively still. Under the condition of ensuring that the interior of the rotary furnace cavity is airtight, the discharge and gas outlet are both set in the center, and the gas outlet pipe is forked to bypass the automatic discharger and then intersect, so that the discharge and gas outlet do not interfere with each other, which solves the defect of the above-mentioned interference between gas outlet and discharge.

[0007] Furthermore, the automatic unloader includes a support cover located outside the discharge port, a telescopic mechanism located on and passing through the support cover, and a sealing disk located at the end of the telescopic mechanism and close to one side of the discharge port, the telescopic mechanism is fixed on the support cover, and a plurality of discharge ports are arranged on the side wall of the support cover. During the sludge treatment process, the sealing disk is located at the discharge port to isolate the rotary furnace from the outside, prevent the outside air from entering the rotary furnace, and effectively reduce the heat loss in the rotary furnace. After the sludge treatment is completed, the telescopic mechanism drives the sealing disk to move, the discharge port is opened, the material falls from the discharge port, and flows out from the discharge port. After the discharge is completed, the telescopic mechanism drives the sealing disk to the discharge port, and the rotary furnace is in a closed state; the rotary furnace rotates, driving the support cover to rotate, and the rotation of the support cover drives the telescopic mechanism and the sealing disk to rotate; through the arrangement of the support cover, the sealing disk and the driving mechanism, the automatic unloading device has good heat insulation and sealing performance, and at the same time, the sealing requirements under high temperature environment are achieved, so that the inside of the rotary furnace is effectively isolated from the outside world, and the loss of heat energy is reduced.

[0008] Furthermore, the telescopic mechanism includes a push-pull rod fixed to the side of the sealing disk away from the discharge port and a driving mechanism connected to the push-pull rod, a bearing seat is provided on one side of the support cover, the push-pull rod passes through the bearing seat, a bearing is provided on the outer periphery of the push-pull rod, the bearing is fixed in the bearing seat, and the driving mechanism is fixed on the bearing seat. The driving mechanism drives the push rod to drive the sealing disk to telescope back and forth to close or open the discharge port.

[0009] Furthermore, the driving mechanism includes a hydraulic cylinder or a pneumatic cylinder, which is easy to control and has a high degree of automation.

[0010] Furthermore, the hydraulic cylinder or the pneumatic cylinder is controlled by a PLC. The PLC controls the extension and retraction of the hydraulic cylinder or the pneumatic cylinder, thereby driving the telescopic rod and the sealing disk to extend and retract back and forth, realizing opening or closing of the discharge port, so that the discharge is automatically controlled.

[0011] Furthermore, the rotary furnace, the discharge port and the sealing disk are coaxially arranged, so that the sealing disk and the discharge port rotate together, and the sealing disk retracts back and forth, thereby closing or opening the discharge port.

[0012] Furthermore, the sealing disk is made of high temperature resistant and heat insulating material, and has good heat insulating and sealing effects.

[0013] Based on the above description, compared with the prior art, the present invention has the following beneficial effects: (1) Under the condition of ensuring that the interior of the rotary furnace is airtight, the unloading and the gas outlet are both arranged in the center, and the gas outlet pipe is bifurcated and then intersected after bypassing the automatic unloader, so that the unloading and the gas outlet do not interfere with each other; (2) The rotary furnace, the automatic unloader and the gas outlet intersection pipe are coaxially arranged to ensure that the automatic unloader and the gas outlet intersection pipe rotate with the rotary furnace, and the sealed exhaust pipe is relatively stationary; (3) Through the arrangement of the support cover, the sealing disk and the driving mechanism, the automatic unloading device has good thermal insulation and sealing performance, and at the same time, the sealing requirements under high temperature environment are met, so that the interior of the rotary furnace is effectively isolated from the outside world, and the loss of heat energy is reduced; (4) PLC controls the extension and contraction of the hydraulic cylinder or the pneumatic cylinder, thereby driving the extension rod and the sealing disk to extend and retract back and forth to realize the opening or closing of the discharge port, so that the discharge is automatically controlled; (5) The rotary furnace, the discharge port and the sealing disk are coaxially arranged, so that the sealing disk rotates together with the discharge port, and the sealing disk extends and retracts back and forth to realize the closing or opening of the discharge port.
