Description

Technical Field

[0001] The utility model belongs to the field of dust removal devices, and in particular relates to a track cleaning and dust collection device for a coking coal loading car. Background Art

[0002] During the coking process in the coke oven, a large amount of coal powder, coke powder and dust are often scattered on the coking coal loading car tracks due to various reasons such as the coal loading gate not being closed tightly, insufficient negative pressure in the dust removal pipeline, and untimely coal leveling. If they are not cleaned in time, it is easy to cause dust flying, dust accumulation and other serious environmental pollution. Therefore, the coking plant needs to clean the coking coal loading car tracks regularly.

[0003] At present, when cleaning and dusting the coking coal loading car track, most coking plants use manual cleaning due to the irregular structure of the coking coal loading car track and the special location of the coking coal loading car track. However, this cleaning method has problems such as high labor intensity, poor cleaning effect, low efficiency, and is likely to bring great safety hazards to the cleaning workers.

[0004] In addition, some coking plants will install a purge device on the coal loading car to clean the furnace roof track. For example, Chinese patent CN216837812U once provided a coke oven door and coking machinery vehicle track purge device used on a coal loading car. However, since the purge device provided by it only has a blowing function, it not only cannot effectively clean the track and the root of the track foundation during actual application, but also easily causes powder overflow, thereby causing the entire cleaning environment to become worse. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a coking coal loading car track cleaning and dust collection device which can thoroughly blow up the coke powder inside the coking coal loading car track and at the bottom of the foundation and absorb it into the coal box for recycling and reuse, and makes the entire cleaning process both economical and environmentally friendly.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a coking coal loading car track cleaning and dust collection device, which includes an air compressor that can be installed on the coal loading car, and the output end of the air compressor is connected to a left blowing pipe and a right blowing pipe through a purge pipeline; it also includes a dust suction fan that can be installed on the coal loading car, and the input end of the dust suction fan is connected to a dust suction hood through a dust suction pipeline, and the left and right sides of the dust suction hood are sequentially provided with a track suction part and a track foundation suction part from the inside to the outside, and a suction channel 1 is provided inside the track foundation suction part, and a suction channel One is connected to the dust suction pipeline; a track foundation suction port is provided on one side and / or the bottom of the track foundation suction part facing the track foundation, and the track foundation suction port is connected to suction channel one; a suction channel two is provided inside the track suction part, and a track suction port is provided at the bottom of the suction channel two; the left blowing pipe is arranged between the track foundation suction part and the track suction part on the left side of the dust hood, and the right blowing pipe is arranged between the track foundation suction part and the track suction part on the right side of the dust hood, and both the left blowing pipe and the right blowing pipe have a lower blowing port and a track foundation table blowing port. At this time, when the utility model is used to clean the coking coal loading car track, the utility model can wrap the coking coal loading car track and the track foundation through the dust hood, and under the combined action of blowing and suction, the purpose of blowing without overflow and timely sucking away dust is achieved, thereby improving the overall cleaning effect and making the entire cleaning process both economical and environmentally friendly.

[0007] Furthermore, the rail suction port is arranged to be inclined inwardly so as to absorb coal powder and the like accumulated at the web position of the rail of the coking coal charging car.

[0008] Furthermore, the air blowing port of the track foundation table is arranged to be inclined downward, and in actual application, it is higher than the table of the track foundation to ensure that the coal powder and the like dropped from above the track foundation can be blown up.

[0009] Furthermore, a flexible protective strip is provided at the bottom of the rail foundation suction part so that the dust hood can fit tightly against the coking coal loading car rail and the rail foundation part, so that the compressed air generated by the air compressor can fully blow up the dust in the gap. At the same time, due to the effective sealing of the flexible protective strip, the dust is difficult to overflow, thereby ensuring that it can be fully absorbed into the coal box for recycling and reuse.

[0010] Furthermore, the coking coal loading car track cleaning and dust collection device also includes a lifting drive mechanism that can be installed on the coal loading car, and a connecting frame is installed at the power output end of the lifting drive mechanism. The connecting frame and the dust hood are installed together through fasteners. At this time, the utility model can drive the dust hood to move up and down through the lifting drive mechanism to separate the dust hood from the coking coal loading car track.

[0011] Furthermore, the dust suction pipeline is a soft pipe to ensure that the dust suction hood can move up and down.

[0012] Furthermore, the coking coal loading car track cleaning and dust collection device also includes a sensor that can be installed on the coal loading car and a sensing probe that can be installed on the coking coal loading car track. The sensing probe and the sensor are connected in communication, so that when the coal loading car moves to a specified position, the sensor is connected in communication with the sensing probe installed on the coking coal loading car track, and can receive signals to control the lifting drive mechanism to perform corresponding actions to separate the dust collection hood from the coking coal loading car track. In addition, it should be noted that the inductive coordination between the sensing probe and the sensor, as well as the receiving of signals by the sensor and the control of the lifting drive mechanism to perform corresponding direction actions are both relatively mature sensor technologies on the market. The utility model here directly applies the existing technology and does not involve its modification.

[0013] Furthermore, the output end of the dust suction fan is connected to a filter separator through a pipeline, a scraper is provided below the output end of the filter separator, and a coal box is provided at the output end of the scraper. At this time, the powder such as coke powder sucked by the dust suction fan can be first transported to the filter separator through a pipeline, and then the powder discharged after cyclone separation in the filter separator can directly fall into the scraper, and under the action of the scraper, it can be transported to the coal box for recovery.

[0014] It can be seen from the above technical scheme that the utility model has the following advantages: First, when the utility model is used to clean the coking coal loading car track, the utility model can wrap the coking coal loading car track and the track foundation through the dust hood, and under the combined action of blowing and suction, the purpose of blowing without overflow and timely sucking away dust can be achieved, thereby improving the overall cleaning effect and making the entire cleaning process economical and environmentally friendly; secondly, the utility model can also lift the dust hood in time when the coal loading car walks to the specified position, so as to avoid the problem of incorrect coal weight on the coal loading car.
