Description
Technical Field
The invention belongs to the field of cement production and municipal waste treatment, and particularly relates to an anti-backfire rotary cement kiln device.
Background
The method for utilizing the cement kiln to dispose the municipal solid waste in coordination in the cement production process accords with the concept of sustainable development and is an effective way for improving the traditional cement industry. The rotary kiln is a main device of a cement clinker production line, when the rotary kiln system has operation faults, positive pressure of a decomposing furnace can be caused to cause tempering, garbage combustible matters are disposed after urban domestic garbage is cooperatively disposed, and serious potential safety hazards exist; the process flow at the upper part of the preheater of the prior combustible material system is as follows: the material is carried to flat belt to a square three-way airlock valve again through oblique belt, then get into the sealed reamer of single tube, carry into inside the preheater dore furnace, if the outage of whole factory can lead to the valve plate to close when air feed pressure is not enough or the unable valve plate that promotes of cylinder, can't keep apart burning things and combustible substance completely, the intensity of a fire can be scurried single tube reamer along combustible substance, the unloading chute, until oblique belt, burn out the oblique belt of combustible substance, cause the equipment accident, seriously influence combustible substance system safe operation.
Disclosure of Invention
The invention provides an anti-backfire rotary cement kiln device, which can effectively avoid accidents caused by the fault backfire of a rotary kiln system by modifying an air locking valve.
In order to achieve the purpose, the invention adopts the following technical scheme:
an anti-backfire rotary cement kiln device, comprising: the inclined belt head is connected with flat belt scale one end, the flat belt scale other end is connected with single tube sealing reamer one end through the scraper-trough conveyer, the single tube sealing reamer other end is connected the airlock valve, the dore is connected to the airlock valve other end one section is cut off and two section mounting flange dish about at the scraper-trough conveyer middle part, the flange dish is connected with pneumatic valve plate respectively, near pneumatic valve plate increase a gas holder, the gas holder through give vent to anger the pipeline with pneumatic valve plate connects, connect the check valve on the admission line of gas holder.
In the structure, the single-tube sealing reamer is connected with the air locking valve through the flange plate bolt, the air locking valve is a single-plate air locking device, an air locking valve plate is arranged inside the single-plate air locking device, two valve arms are arranged outside the single-plate air locking device, the counter weight is added on the valve arms according to the internal air locking effect, when combustible garbage is conveyed to the air locking valve plate, the air locking valve plate opens the discharge, and the air locking valve and the decomposing furnace shell are welded into a whole.
Has the advantages that: the invention provides an anti-backfire cement rotary kiln device, which is characterized in that three square air locking valves in the original device are disassembled to be changed into a slide carriage, two square pneumatic valve plates are arranged on the slide carriage, once a rotary kiln process accident happens, a central control operator closes the two valve plates immediately to isolate combustible materials from a fire source, and a company adds an air storage tank near the pneumatic valve plates and adds a one-way valve on an air inlet pipeline to ensure that compressed air can only not enter out in consideration of the situation that the valve plates cannot be closed in place or an air cylinder cannot push the valve plates to completely isolate the fire source from the combustible materials when the air supply pressure is insufficient due to the power failure of the whole plant. Therefore, even if the gas is cut off or the gas is tripped, the two valve plates can be closed in time through the compressed air in the gas storage tank to ensure that complete combustible materials are completely isolated from a fire source, and in addition, in order to reduce the air leakage rate of the system and prevent backfire, a set of air locking valve is additionally arranged at the joint of the combustible single-tube sealing reamer head and the decomposing furnace. The accident caused by the fault tempering of the rotary kiln system is effectively controlled through the transformation, and the air leakage of the system is reduced.

FIG. 2 is a schematic view of the apparatus of the present invention.
Detailed Description
The invention is described in detail below with reference to the following figures and specific examples:
an anti-backfire rotary cement kiln device, comprising: the inclined belt head is connected with flat belt scale one end, the flat belt scale other end is connected with single tube sealing reamer one end through the scraper-trough conveyer, the single tube sealing reamer other end is connected the airlock valve, the dore is connected to the airlock valve other end one section is cut off and two section mounting flange dish about at the scraper-trough conveyer middle part, the flange dish is connected with pneumatic valve plate respectively, near pneumatic valve plate increase a gas holder, the gas holder through give vent to anger the pipeline with pneumatic valve plate connects, connect the check valve on the admission line of gas holder.
In the structure, a single-tube sealing reamer is connected with an air locking valve through a flange plate bolt, the air locking valve is a single-plate air locking device, an air locking valve plate is arranged inside the single-plate air locking device, two valve arms are arranged outside the single-plate air locking device, a counter weight is added on the valve arms according to the internal air locking effect, the air locking effect is guaranteed, the single-plate air locking device is in a closed state under the normal condition, combustible garbage is conveyed to the air locking valve plate through the sealing reamer, the material overcomes the resistance of the valve plate self weight and the external valve arms and the counter weight through the thrust of the sealing reamer to push the valve plate open, and the air locking valve is welded with a decomposition furnace shell into.
Through improving traditional device, demolish three square air-lock valves and become the swift current son, and install two square pneumatic valve plates on the swift current son, in case take place rotary kiln technology accident and close twice valve plate by well accuse operator immediately, isolated combustible substance and burning things, can lead to leading to the valve plate to close not in place or the cylinder can't promote the valve plate when considering that the whole factory outage leads to air supply pressure not enough, can't keep apart burning things and combustible substance completely, the company increases a gas holder near pneumatic valve plate, and increase a check valve on the admission line and ensure that compressed air can only not advance. Therefore, even if the gas is cut off or the gas is tripped, the two valve plates can be closed in time through the compressed air in the gas storage tank to ensure that complete combustible materials are completely isolated from a fire source, and in addition, in order to reduce the air leakage rate of the system and prevent backfire, a set of air locking valve is additionally arranged at the joint of the combustible single-tube sealing reamer head and the decomposing furnace. The accident caused by the fault tempering of the rotary kiln system is effectively controlled through the transformation, and the air leakage of the system is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
