Description

Technical Field

[0001] The utility model belongs to the technical field of waste rubber and plastic pyrolysis, in particular to a device for preparing rubber particles from waste rubber blocks. Background Art

[0002] Pyrolysis of scrap tires is an irreversible thermochemical reaction that uses high temperatures in an oxygen-free or oxygen-deficient atmosphere to decompose the total organic matter in scrap tires, releasing volatile products and forming solid coke. During the incomplete thermal degradation process, gaseous, liquid, and solid products are formed. This method can completely pyrolyze scrap tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases.

[0003] The raw materials used for pyrolysis in continuous pyrolysis equipment are generally waste rubber. However, in order to maintain the sealing of the feeder during feeding, there are also requirements for the raw materials. For example, if the raw materials are cut into a size of about 50mm×80mm, the feeder cannot be sealed during feeding, and the steel wire content in the rubber block is basically not removed. This will accelerate the wear and blockage of the feeder, causing safety accidents. In order to ensure smooth feeding of the feeder and achieve a good sealing effect, a rubber crusher is needed to break the 50mm×80mm large rubber blocks into irregular pieces of rubber less than 20mm to meet the pyrolysis requirements.

The waste rubber block pelletizing equipment uses a cutter head 1014 to tear the waste rubber blocks into pieces, and can completely tear the waste tires into small pellets, greatly reducing the volume of the waste tires and facilitating subsequent processing. By limiting the structural form of the cutter head mounting position 1013 and the installation form of the cutter head 1014, it is ensured that the waste rubber blocks can be quickly rolled into the vicinity of the cutter head 1014 and then the cutter head 1014 is used to cut the waste rubber blocks into pieces.

[0029] In order to improve efficiency and facilitate disassembly and maintenance, a number of cutter head mounting seats 1012 are sleeved outside the roller shaft 1011 and arranged in sequence along the roller shaft 1011. The cutter head mounting seats 1012 are detachably fixedly connected to the roller shaft 1011.

[0030] To ensure the crushing effect of the waste rubber blocks, the crusher includes a housing 102, and at least two sets of rubber crushing roller assemblies 101 are arranged in the inner cavity surrounded by the housing 102, and the rubber crushing roller assemblies 101 are arranged in parallel. Furthermore, adjacent rubber crushing roller assemblies 101 on the same horizontal plane rotate in opposite directions.

[0031] In some embodiments, the cutter head 1014 is fixed in the cutter head mounting position 1013 by a hexagon socket bolt 1015 , and the hexagon socket bolt 1015 is provided on a hexagon socket bolt mounting seat 1016 opened on the outer peripheral side surface of the cutter head mounting seat 1012 .

[0032] Furthermore, the rubber breaking roller assembly 101 further includes a transmission motor 1017 for driving the roller shaft 1011 to rotate. At the same time, each roller shaft 1011 is equipped with an independent transmission motor 1017 so as to independently control the rotation direction of each roller shaft 1011.

[0033] In some of the embodiments, a skid-mounted traveling frame is further included for moving the equipment for making rubber pellets from waste rubber blocks.

[0034] Furthermore, the scrap rubber pelletizing equipment is a skid-mounted four-roller structure for crushing scrap rubber pellets. The crusher is equipped with four sets of crusher rollers 1011: an upper left-side 1# crusher roller assembly 101, an upper right-side 2# crusher roller assembly 101, a lower left-side 1# crusher roller assembly 101, and a lower right-side 2# crusher roller assembly 101. These four crusher rollers 1011 are mounted on the crusher frame. The two upper rollers are mounted side by side, and the two lower rollers are also mounted symmetrically using two rollers 1011. Each of the four crusher roller assemblies 101 is driven independently by a drive motor 1017 on the upper left, a drive motor 1017 on the upper left, a drive motor 1017 on the upper left, a drive motor 1017 on the lower left, and a drive motor 1017 on the lower left. Each of the four rubber-breaking roller assemblies 101 is equipped with a front bearing seat and a rear bearing seat. To prevent displacement during use, tensioning cylinders are installed on the upper left and right bearing seats, as well as on the lower left and right bearing seats. These cylinders automatically monitor the gap.

The blade mounting base 1012 is arranged around the circumference and is equipped with four sets of hexagon socket bolt mounting bases 1016 securing the rubber-breaking blade 1014, and a rubber-breaking blade mounting position 1013. The rubber breaking cutter head 1014 is placed on the rubber breaking cutter head mounting position 1013 and is fixed on the cutter head 1014 fixing hexagon socket bolt mounting seat 1016 using the rubber breaking cutter head 1014 fixing hexagon socket bolt 1015 .

[0035] Some embodiments further include a first conveyor belt 2 connected to the crusher feed port, and a silo 3 connected to the feed port of the first conveyor belt 2. The silo 3 comprises a silo body and a support bracket for supporting the silo body. A vibration spring is positioned between the silo body and the support bracket, and a vibrator is mounted on the silo body. Waste tires and waste rubber are cut into blocks approximately 50 mm x 80 mm using a specialized cutting tool. The pyrolyzed rubber blocks are then loaded into the rubber block raw material silo 3 using a loading tool. The feed port of the rubber block raw material silo 3 is located at the top of the silo. To prevent rubber blocks from bridging within the rubber block raw material silo 3, the silo body and its lower support bracket are designed as separate structures. Vibration springs are positioned between the rubber block raw material silo 3 and the support bracket, one at each of the four corners. Two vibrators are located on each side of the lower portion of the waste rubber block raw material silo 3 to vibrate the silo body and ensure smooth material discharge. The lower portion of the rubber block raw material silo 3 is secured to the left floor of the skid-mounted traveling frame with four columns. The discharge port of the rubber block raw material bin 3 is set at the bottom and docked with the feed port of the first conveyor belt 2 of the waste rubber block. The discharge port of the first conveyor belt 2 of the waste rubber block is set on the right side, and the conveyed 50mm×80mm large rubber blocks enter the feed port of the crusher frame.

[0036] It further includes a second conveyor belt 4 connected to the crusher discharge port. After the colloid particles that meet the pyrolysis requirements are crushed, they are discharged from the crusher frame discharge port below the crusher frame into the iron remover conveyor belt (second conveyor belt 4) for magnetic separation to remove the residual steel wire in the colloid particles. A permanent magnet block for the iron remover is provided at the lower part of the iron remover conveyor belt, which can adsorb the steel wire in the colloid particles onto the iron remover conveyor belt. As the iron remover conveyor belt moves to the right, the right end of the colloid particles falls into the iron remover colloid particle discharge port, and the colloid particles enter the conveyor feed port, move to the right by the conveyor, and are unloaded into ton bags at the discharge port for standby use. The steel wire adsorbed on the iron remover conveyor belt by the permanent magnet block for the iron remover continues to move downward and to the left. The lower part of the iron remover conveyor belt bracket is also provided with a permanent magnet block for the iron remover, which adsorbs the steel wire and unloads it into the iron remover steel wire outlet at the left end. The rubber crusher assembly is fixed to the center of the skid-mounted traveling frame. The rubber pellet discharge port of the lower iron remover is connected to the rubber pellet feed port of the conveyor. Six self-supporting wheels are installed on the left side of the skid-mounted traveling frame. During operation, the skid-mounted traveling frame cylinder supports are extended. The skid-mounted traveling frame cylinder supports are symmetrically arranged left and right, front and back.
