Description

Technical Field

[0001] This utility model belongs to the field of pelletizing machine technology, specifically relating to a coke pelletizing machine. Background Technology

[0002] Coke is an important raw material for blast furnace ironmaking. Its reactivity and post-reaction strength are key indicators for evaluating the thermal properties and skeletal function of coke. At present, coke pelletizing machines are widely used in coke reactivity tests to process irregular coke particles into spherical coke to meet the strict requirements of the test on the shape, particle size and uniformity of the sample.

[0003] In patent application CN202322926812.6, a fully automatic coke pelletizing device is proposed. This fully automatic coke pelletizing device sets the vibrator away from the silo and connects it to the pelletizing screen through a bracket, which can reduce the noise generated by vibration.

[0004] However, in the existing technology, the separation effect of spherical coke from debris and dust is not good during the coke crushing and shaping process. This can easily cause debris to be mixed into the finished product or dust to accumulate, affecting the accuracy of subsequent test results. In addition, the existing sieve plates are usually fixed with bolts. This fixing method is prone to loosening or displacement under continuous and strong vibration and impact, thus affecting the screening accuracy and equipment life. Utility Model Content

[0005] Based on the above-mentioned technical problems, the purpose of this utility model is to provide a coke pelletizing machine. This device improves the separation effect of spherical coke from debris and dust through the coordinated action of the screen plate assembly, the discharge screening mechanism and the ash receiving assembly, reducing the problem of debris mixing into the finished product or dust accumulation. The screen plate assembly is fixed by the locking mechanism, which not only ensures the stability of the screen plate assembly under high-frequency vibration, but also avoids structural damage caused by direct rigid contact, thereby extending the service life of the equipment and maintaining the screening accuracy.

[0006] The specific technical solution is as follows:

[0007] A coke briquetting machine includes: a housing, a hammering assembly, a screen plate assembly, a locking mechanism, a discharge screening mechanism, and an ash receiving assembly.

The locking cylinders are located on both sides of the housing, and their extension / retraction ends are connected to the locking heads, which press against the rubber blocks when locking. The discharge screening mechanism is located inside the discharge chamber and below the screen plate assembly. The ash receiving assembly is located inside the ash receiving chamber and below the discharge screening mechanism.

[0008] In addition, the coke briquetting machine provided by this utility model may also have the following additional technical features:

[0030] The following are specific implementation cases and appendices. Figure 1-8 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] A coke pelletizing machine, such as Figure 1-8As shown, the assembly includes: a housing 10, a hammering assembly, a screen plate assembly, a locking mechanism, a discharge screening mechanism, and a dust receiving assembly. The housing 10 contains a ball-forming chamber, a screening chamber, a discharge chamber, and a dust receiving chamber. A liner 11 is provided inside the ball-forming chamber. The hammering assembly is located inside the ball-forming chamber and is connected to the output end of the drive device. Slides 35 are provided on both sides of the screening chamber. The screen plate assembly is located on the slides 35 and below the hammering assembly. The locking mechanism includes a locking cylinder 12, a locking head 13, and rubber blocks 14. The rubber blocks 14 are fixed on both sides of the screen plate assembly. The locking cylinders 12 are respectively located on both sides of the housing 10. The extension and retraction ends of the locking cylinders 12 are connected to the locking head 13, and the locking head 13 presses against the rubber blocks 14 when locking. The discharge screening mechanism is located inside the discharge chamber and below the screen plate assembly. The dust receiving assembly is located inside the dust receiving chamber and below the discharge screening mechanism.

[0032] With the above structure, the housing 10 is divided into a ball-forming chamber, a screening chamber, a discharge chamber, and an ash-receiving chamber. Coke particles enter the ball-forming chamber from the feed inlet. The drive device drives the hammer assembly to operate, so that the hammer assembly cooperates with the liner plate 11 to strike the coke at high speed, gradually grinding it into a ball shape. The spherical coke falls into the screen plate assembly by gravity, and qualified spherical coke passes through the screen holes of the screen plate assembly and falls into the discharge screening mechanism for further screening. This improves the separation effect of spherical coke from debris and dust. The debris and dust fall into the ash-receiving assembly, achieving the purpose of dust recovery and preventing dust from escaping into the atmosphere and causing pollution. The locking cylinder 12 controls the locking head 13 to press against the rubber block 14, thereby fixing the position of the screen plate assembly and preventing the screen plate from loosening or shifting during operation.

[0033] Specifically, the drive device includes a motor 31, a drive pulley 32, a driven pulley 33, and a belt 34. The output end of the motor 31 is connected to the drive pulley 32. The driven pulley 33 is located at the main shaft 15 of the hammer assembly and is simultaneously located on the outside of the drive pulley 32 and the driven pulley 33 via the belt 34, thereby realizing the function of transmitting power to the main shaft 15.

[0034] Specifically, the motor 31 controls its speed through a frequency converter, so that the equipment can select three modes of ball making: high-speed ball making, medium-speed ball making, and low-speed ball making during operation.

[0035] Specifically, this device is also equipped with a dust removal system, which is connected to the dust collection chamber and kept running throughout the entire operation of the device to purify the dust generated during the pelletizing process.

[0036] The dust removal system in this embodiment includes a centrifugal fan and a filter cartridge dust collector, and the dust removal system is connected to the dust collection chamber through a connecting pipe.

[0037] In embodiments of this utility model, such as Figure 1-4 As shown, the hammering assembly includes: a main shaft 15, a fixed plate 16, a hammer shaft 17, and a hammer head 18; the main shaft 15 is disposed in the ball-making cavity and connected to the output end of the drive device, the main shaft 15 is provided with two fixed plates 16, the two ends of the hammer shaft 17 are respectively fixed on the two fixed plates 16, and the hammer head 18 is mounted on the hammer shaft 17.

[0038] Driven by the drive device, the main shaft 15 rotates. During the high-speed rotation of the hammer head 18, the coke particles are thrown towards the liner plate 11 on the inner wall of the ball-making chamber by centrifugal force. The combined action of impact force, friction force and grinding force makes the coke particles gradually flattened and form spheres.

[0039] In embodiments of this utility model, such as Figure 1-5 As shown, the sieve plate assembly includes a sieve box 19 and a shaping sieve plate 20. The side wall of the sieve box 19 is provided with a through groove 21. The shaping sieve plate 20 is disposed on the top surface of the sieve box 19 and is arc-shaped.

[0040] Coke particles, debris, and dust, ground into spherical shapes, fall through the sieve holes of the shaping sieve plate 20, thereby achieving the purpose of preliminary screening of coke. Furthermore, the design of providing through grooves 21 on the side wall of the screening box 19 can reduce dust accumulation.

[0041] Specifically, the screening box 19 is a hollow cavity with openings on both the upper and lower sides.

[0042] In an embodiment of this utility model, a first slag discharge trough 22 is provided on the slide 35.

[0043] By providing a through groove 21 on the side wall of the screening box 19 and a first slag discharge groove 22 on the slide 35, most of the dust accumulated in the screening box 19 and the slide 35 can fall off, thereby reducing the occurrence of sedimentation.

[0044] In embodiments of this utility model, such as Figure 1-6 As shown, the discharge screening mechanism includes: a receiving box 23, a guide rod 24 and a receiving plate 25. The guide rod 24 is inclinedly arranged in the receiving box 23, the receiving plate 25 is located on one side of the guide rod 24, and a second slag discharge trough 26 is provided on the receiving plate 25.

[0045] Coke particles passing through the shaping screen plate 20 move along the guide rod 24 to the receiving plate 25. Debris and dust fall through the gaps between the guide rods 24, achieving a second separation. Dust mixed in with the coke particles accumulated on the receiving plate 25 can also fall through the second slag discharge trough 26, thereby improving the separation effect.

[0046] Specifically, the receiving box 23 is a hollow cavity with openings on both the top and bottom sides.

[0047] In embodiments of this utility model, such as Figure 1 As shown, the ash receiving assembly includes: an ash receiving box 27, an ash guide plate 28, and an ash receiving groove 29. The ash receiving box 27 is provided with ash guide plates 28 on both sides, and the ash receiving groove 29 is located inside the ash receiving box 27, with the ash guide plates 28 and the ash receiving groove 29 being positioned opposite each other.

[0048] The dust and debris are guided by the dust guide plate 28 so that they fall into the dust collection trough 29 for collection.

[0049] In an embodiment of this utility model, guide plates 30 are provided on both sides of the screening chamber, and the guide plates 30 are located below the slide 35.

[0050] The spherical coke passing through the shaping screen plate 20 smoothly enters the receiving box 23 under the action of the guide plate 30, which serves as a guide.

[0051] In an embodiment of this utility model, an auxiliary cylinder 36 is also included; the auxiliary cylinder 36 is disposed behind the screening box 19, and the telescopic end of the auxiliary cylinder 36 is connected to the screening box 19.

[0052] First, the locking cylinder 12 is released, causing the locking head 13 to move away from the screening box 19. Then, the auxiliary cylinder 36 is operated to push out the screening box 19, so that the operator can check for any residue.

[0053] Implementation process:

[0054] S1: When in use, connect the power supply, turn on the control cabinet, and the touch screen will light up. The touch screen has three ball-making types: high-speed ball making, medium-speed ball making, and low-speed ball making. The operator selects the appropriate mode according to the needs. In addition, the touch screen also has functions such as time and speed.

[0055] S2: After selecting the ball-making mode, start the equipment. The locking cylinder 12 controls the locking head 13 to press against the rubber block 14, thereby fixing the position of the screen plate assembly and preventing the screen plate assembly from vibrating or shifting. The main shaft 15 is rotated by the combination of the motor 31, the drive wheel 32, the driven wheel 33, and the belt 34, which in turn drives the hammer head 18 to rotate.

[0056] S3: Coke is fed into the feed port and falls into the pelletizing chamber. After being crushed and ground by the hammer 18 and the liner 11, the spherical coke that meets the specifications falls into the receiving box 23 through the screen holes of the shaping screen plate 20. Fine dust and debris fall into the ash receiving trough 29.

[0057] S4: After ball making is completed, locking cylinder 12 is opened and auxiliary cylinder 36 pushes out shaping screen plate 20 so that operators can check for any residue.

[0058] S5: Open the receiving box 23 and take out the qualified coke ball.

[0059] The dust removal system is connected to the ash receiving chamber and is kept running throughout the entire operation of the equipment to purify the smoke and dust generated during the pelletizing process.
