Description

Technical Field

[0001] This utility model relates to the technical field of screening and distributing systems, and in particular to an automatic coke particle size screening and distributing system. Background Technology

[0002] Blast furnace ironmaking has requirements for the particle size composition of coke. Coke entering the plant needs to be tested for its particle size composition using a multi-stage cylindrical screen. The bottom of the multi-stage cylindrical screen is connected to multiple silos, and proportioning is carried out by a reduction weighing method. In traditional coke automatic particle size screening system and proportioning system, the process is too long, the material transfer distance is increased, and the proportioning efficiency is low. When proportioning coke of multiple particle sizes, the material of the previous proportioning process needs to be transported out before the proportioning of other particle sizes of coke can be carried out, which further reduces the proportioning efficiency. In order to address the above defects, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic coke particle size distribution system, which solves the problems of long and inefficient particle size distribution and proportioning processes at present.

[0004] To address the aforementioned problems, this utility model provides an automatic coke particle size distribution system, comprising a feeding conveying mechanism, a multi-stage cylindrical screen, a silo mechanism, a proportioning conveying mechanism, and a rotating sample cylinder disk connected in sequence. The silo mechanism includes a reducing scale and a silo. The rotating sample cylinder disk includes a turntable, a sample barrel, and a rotation drive assembly. The rotation drive assembly drives the turntable to rotate. Several sample barrels are arranged and placed on the turntable. In the proportioning state, the silo mechanism releases material to the proportioning conveying mechanism. The sample barrels are used to receive the proportioned material from the proportioning conveying mechanism. After one proportioning is completed, the rotation drive assembly drives the turntable to rotate and switch the sample barrel connected to the proportioning conveying mechanism for the proportioning of the next sample, thereby improving proportioning efficiency.

[0005] According to one embodiment of the present invention, the rotating sample cylinder further includes a weighing component, which is used to weigh the sample cylinder. Preferably, the weighing component adopts a lifting weighing method.

[0006] According to one embodiment of the present invention, the weighing component is electrically connected to the rotary drive component and the proportioning conveying mechanism. When the sample in the sample barrel reaches the set weight, the proportioning conveying mechanism stops proportioning and conveying, and the rotary drive component drives the turntable to rotate and switch sample barrels.

[0007] According to one embodiment of the present invention, the proportioning conveying mechanism is connected to the waste material conveying mechanism and is used to unload the proportioned waste material.

[0008] According to one embodiment of the present invention, the automatic coke particle size distribution system also includes a dust collector to reduce the amount of dust on site.

[0009] According to one embodiment of the present invention, the multi-stage cylindrical screen and the silo mechanism are connected by a material conveying mechanism.

[0010] According to one embodiment of the present invention, the material conveying mechanism includes a lifting belt to raise the material to a height, facilitating the release of material from the silo mechanism.

[0011] According to one embodiment of the present invention, the feeding conveyor mechanism includes a feeding belt and a feeding port.

[0012] According to one embodiment of the present invention, the turntable is provided with a sample barrel positioning structure, which can be achieved by providing a groove for placing the sample barrel or a protrusion structure for restricting the sample barrel on the turntable.

[0013] According to one embodiment of the present invention, the bottom of the proportioning conveying mechanism is provided with a discharge port, and the rotating sample cylinder is arranged below the proportioning conveying mechanism, thereby saving equipment space.

[0014] The beneficial effects of this utility model are that by setting up a feeding conveyor mechanism, a multi-stage cylindrical screen, a silo mechanism, and a proportioning conveyor mechanism connected in sequence, the entire process of coke screening and proportioning is automated. Compared with the traditional method of completing the process step by step with two sets of equipment, the efficiency is higher. In addition, this solution is equipped with a rotating sample cylinder plate, which can switch the sample cylinder to receive different samples when making multiple sample proportions, eliminating the need for frequent sample handling and further improving the overall proportioning efficiency.

[0019] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0020] Automatic coke particle size distribution system, such as Figure 1It includes a feeding conveyor mechanism, a multi-stage cylindrical screen 07, a silo mechanism 04, a proportioning conveyor mechanism 08, and a rotating sample cylinder 09 connected in sequence.

[0021] The feeding and conveying mechanism includes a feeding belt 05 and a feeding port 03. The multi-stage cylindrical screen 07 is connected to the silo mechanism 04 through a material conveying mechanism, which includes a lifting belt 06 to lift the material to a height to facilitate the release of material from the silo mechanism 04.

[0022] In this embodiment, the multi-stage cylindrical screen 07 is a five-stage cylindrical screen, matched with five sets of hopper mechanisms 04.

[0023] The proportioning conveyor mechanism 08 adopts a belt mechanism. The feeding belt 05, the lifting belt 06, and the conveyor belt of the proportioning conveyor mechanism 08 are all enclosed in the box to reduce dust.

[0024] The proportioning conveying mechanism 08 is connected to the waste material conveying mechanism 01 to unload the proportioned waste material. The waste material conveying mechanism 01 also adopts a belt conveying mechanism. The unloaded material is finally transported out by the transport vehicle 12.

[0025] The bottom of the proportioning conveying mechanism 08 is provided with a discharge port, and the rotating sample cylinder 09 is located below the proportioning conveying mechanism 08, so as to save the equipment space.

[0026] The hopper mechanism 04 includes a reducing scale and a hopper. The rotating sample cylinder disk 09 includes a turntable 92, a sample cylinder 91, and a rotating drive assembly 94. The rotating drive assembly 94 is used to drive the turntable 92 to rotate. Several sample cylinders 91 are provided, preferably six groups, and placed on the turntable 92. The rotating sample cylinder disk 09 also includes a weighing assembly 93, which is used to weigh the sample cylinders 91. Preferably, the weighing assembly 93 adopts a lifting weighing method, which specifically includes a lifting screw and a weighing sensor. A through hole 96 is provided on the turntable 92 at the placement position of each sample cylinder 91 to assist in the completion of weighing. A sample cylinder positioning structure is provided at the position of the sample cylinder 91 on the turntable 92. The sample cylinder positioning structure is a groove or a protrusion on the turntable 92 for positioning the sample cylinder 91 or for limiting the position of the sample cylinder 91.

[0027] In the mixing state, the hopper mechanism 04 releases the material to the mixing conveyor mechanism 08. The sample barrel 91 is used to receive the mixed material on the mixing conveyor mechanism 08. After one mixing is completed, the rotary drive component 94 drives the turntable 92 to rotate and switch the sample barrel 91 that is connected to the mixing conveyor mechanism 08 to carry out the mixing of the next sample, thereby improving the mixing efficiency.

[0028] The weighing component 93 is electrically connected to the rotary drive component 94 and the proportioning conveying mechanism 08. When the sample in the sample barrel 91 reaches the set weight, the proportioning conveying mechanism 08 stops the proportioning conveying, and the rotary drive component 94 drives the turntable 92 to rotate and switch the sample barrel 91.

[0029] The rotary drive assembly 94 preferably includes a motor and gear transmission mechanism to drive the turntable 92, and works with an angle encoder to control the position of the sample barrel. The turntable 92, the rotary drive assembly 94 and the weighing assembly 93 are mounted on the base frame 95. When the sample weight meets the formula requirements, it automatically rotates to the next station.

[0030] Preferably, such as Figure 2 The coke automatic particle size distribution system also includes a dust collector 11 to reduce the amount of dust on site.

[0031] Working steps: After manually unpacking the coke sample, pour it into the feed inlet 03. The sample enters the multi-stage cylindrical sieve 07 for sieving. Samples of different particle sizes fall into the hopper via the conveyor belt 06. After sieving, the samples of each particle size are automatically weighed and recorded. The moisture and industrial analysis common sample, drum sample and thermal reaction sample are proportioned according to the weight of each grade. Excess samples are transported to the designated location via the waste conveyor belt.

[0032] The specific procedure is as follows: Turn on the power to the equipment in control cabinet 02.

[0033] Particle size sieving: After manually unpacking the small sample bags, the samples are poured sequentially into inlet 03. The total feed volume should be controlled within 1300 kg, and the sample particle size should be ≤100 mm. A conveyor belt transports the samples to the inlet of a multi-stage cylindrical sieve 07. A vibrating feeder is installed at the inlet to evenly feed the samples into the multi-stage cylindrical sieve 07. After sieving, the undersize material falls onto the corresponding conveyor belt at the outlet of the cylindrical sieve, separating the samples into five particle sizes: less than 25 mm, 25-40 mm, 40-60 mm, 60-80 mm, and greater than 80 mm. The conveyor belt 06 then transfers the samples to their respective hoppers. After sieving, the system automatically calculates the composition of each particle size using a reducing scale under the hopper. Simultaneously, based on the obtained data, the system automatically sets the sample mixing ratio, moisture content, and total weight of the sample mix. This data can be uploaded to the testing system and stored long-term.

[0034] Particle size distribution: The reducing scale under the hopper starts working. Each particle size bin is set to be dispensed in three batches. The dispensing conveyor belt rotates forward for the first time, and one-third of a 50kg sample from the drum falls into sample container 91. After one batch of drum dispensing is completed, the turntable 92 moves, rotating another sample container 91 under the dispensing conveyor belt. The dispensing of the drum sample, thermal reaction sample, moisture sample, and industrial analysis sample is carried out sequentially. The conveyor belt reverses, and one-third of the remaining material in the bin is unloaded into the waste conveyor mechanism 01. This process is repeated until all samples meet the weight requirements, at which point they are manually removed.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
