Description

Technical Field

[0001] The utility model relates to the technical field of waste slag treatment, in particular to an iron material crushing device. Background Art

[0002] The waste slag from the municipal solid waste incineration power plant is mainly a solid inhomogeneous mixture of slag, glass, ceramics, sand and a small amount of unburned garbage. The chemical properties of the slag are relatively stable, durable and have high strength. The heavy metal leaching concentration of the slag is lower than the corresponding standards of the Hazardous Waste Leaching Toxicity Program HVEP and TCLP test. The slag is a general waste without toxicity and can be directly landfilled or processed for utilization.

[0003] The slag treatment industry currently uses hammer crushers to crush slag. In order to reduce dust, water needs to be added in the crushing stage and subsequent processing procedures, so the subsequent process is called a wet treatment process. During the treatment process, the ferrous metals that have passed the primary magnetic separation, secondary magnetic separation and tertiary magnetic separation will enter the tertiary crusher, that is, the iron material crushing device, in order to separate the slag and compounds wrapped in the iron material. Since the process is designed in an assembly line style, the conveyor belt will continuously feed a large amount of ferrous metal into the feed port of the crushing device, and the size of the feed channel and the internal crushing chamber space capacity are relatively limited. A large amount of metal influx can easily lead to channel blockage and overload operation of the breaker, which can easily cause equipment damage and affect the safety and stability of equipment operation.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The utility model provides Figure 1-Figure 6 The iron material crushing device shown comprises:

[0032] The crusher 1 comprises a casing 101, a feeding hopper 102 is arranged on one side of the top of the casing 101, and a crushing mechanism is arranged inside the casing 101;

[0033] The lining plate 5 is fixed to the inner bottom end of the housing 101, and a plurality of discharge slots 6 are arranged in an array on the bottom side of the lining plate 5;

[0034] The crushing mechanism includes a roller 20 rotatably mounted in the housing 101 above the liner 5, a plurality of fixed disks 3 are arranged in an array on the outer wall of the roller 20, and a plurality of crushing hammers 4 are arranged in an annular array between two adjacent fixed disks 3, a first driving assembly is arranged on the side wall of the housing 101, and the roller 20 is driven to rotate by the first driving assembly;

[0035] The first driving assembly includes a support plate 7 fixed to one side of the casing 101, a first motor 8 is fixedly connected to the top of the support plate 7, an output end of the first motor 8 is connected to a driving wheel 9, one end of the roller 20 extends to the outside of the casing 101 and is connected to a driven wheel 10, and a transmission belt 11 is sleeved between the driven wheel 10 and the driving wheel 9.

[0036] The first motor 8 drives the driving wheel 9 to rotate, and then the driving wheel 9 can drive the driven wheel 10 to rotate through the transmission belt 11, so that the driven wheel 10 drives the roller 20 to rotate, and then the roller 20 drives the fixed plate 3 to rotate, so that the fixed plate 3 drives the breaker 4 to rotate at high speed in the casing 101. At this time, the ferrous metals that have passed the primary magnetic separation, the secondary magnetic separation and the tertiary magnetic separation can be sent into the feed hopper 102 through the conveyor belt.

[0037] A water inlet pipe 21 is provided on one side of the top of the casing 101 close to the material guiding pipe 2 .

[0038] A large amount of water can be added into the casing 101 through the water inlet pipe 21 during the crushing process to reduce the large amount of heat generated by strong squeezing and friction of components, thereby reducing the temperature of the equipment and reducing damage to the equipment.

[0039] The material guiding pipe 2 is connected between the bottom end of the feed hopper 102 and the casing 101, and a switch assembly is provided in the material guiding pipe 2. The side wall of the feed hopper 102 is provided with a second driving assembly, and the interior of the feed hopper 102 is rotatably connected to a rotating rod 13 through a bearing, and the rotating rod 13 is driven to rotate by the second driving assembly, and three fixed plates 14 are provided in a circular array on the outer wall of the rotating rod 13.

[0040] The second driving assembly includes a second motor 12 fixed to one side of the feed hopper 102 , and one end of the rotating rod 13 extends to the outside of the feed hopper 102 and is connected to the output end of the second motor 12 .

[0041] By arranging three annularly distributed fixed plates 14 in the feed hopper 102, and forming a V-shaped receiving tray between the fixed plates 14, the metal material first falls on the receiving tray, and the second motor 12 drives the rotating rod 13 to rotate, so that the rotating rod 13 can drive the three fixed plates 14 to rotate. With the rotation of the fixed plates 14, the metal material on the first V-shaped receiving tray can be introduced into the material guide pipe 2, and the next V-shaped receiving tray replaces the original position to continue receiving the material. In this way, the material is cyclically received and discharged, so that there is a certain interval time for the metal material continuously entering the material guide pipe 2, thereby effectively preventing a large amount of metal from pouring into the casing 101 at the same time, avoiding channel blockage and overload operation of the breaker 4, greatly improving the safety and stability of the equipment operation, and having a good use effect.

[0042] The switch assembly includes two baffles 15 symmetrically connected to the top opening of the material guide pipe 2 through a rotating shaft, the bottom ends of the two baffles 15 are in contact with each other, and a plurality of springs 16 are connected in an array between the two baffles 15 and the inner wall of the material guide pipe 2.

[0043] In addition, by setting a switch component, when the metal material is introduced into the material guide pipe 2, the metal material can flow between the two baffles 15, so that the baffle 15 is forced to squeeze the spring 16, and then the two baffles 15 open to allow the material to flow smoothly into the casing 101. When the material has flowed out, the two baffles 15 are close to each other again under the rebound of the spring 16, so that the material guide pipe 2 can be closed, and then the material guide pipe 2 can be automatically switched on and off to prevent the material and water from being thrown out of the material guide pipe 2 during the crushing process, thereby further improving the safety of the device when in use.

[0044] The utility model provides Figure 4 , Figure 6 and Figure 7In the iron material crushing device shown, connecting arms 17 are symmetrically connected to both ends of the roller 20 and are located in the casing 101. A scraper 18 is fixed between the bottom ends of the two connecting arms 17. The bottom side of the scraper 18 is in contact with the top side of the lining plate 5, and a retaining bar 19 is fixed to one end of the scraper 18.

[0045] The metal material can be quickly crushed into fine particles by the action of the crushing hammer 4 and the collision of the metal material with the liner 5, and the crushed fine iron material can flow out of the crusher 1 along the discharge chute 6 with the flushing water;

[0046] If some fine iron materials still cannot flow out through the discharge chute 6, as the roller 20 drives the connecting arm 17 to rotate, the connecting arm 17 can drive the scraper 18 to rotate along the inner wall of the casing 101. The scraper 18 can scrape the iron materials on it when passing through the discharge chute 6. With the blocking of the baffle 19, the iron materials can be driven to move upward, so that the iron materials can be thrown to the breaker 4 again, and then they can be further crushed, which greatly ensures the crushing effect of the metal materials.

[0047] The scraper 18 is arc-shaped, and a bevel is provided at one end of the scraper 18 relative to the baffle 19. The bevel is provided to facilitate scraping of the material.
