Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste incineration slag treatment technology, and in particular to a municipal solid waste incineration slag crushing opening and closing mechanism and crushing device. Background Technology

[0002] After municipal solid waste is incinerated at high temperatures, a certain amount of municipal solid waste incinerator ash is produced. When the incinerator ash is reused, it needs to be crushed by appropriate devices to reduce its particle size in order to meet different usage requirements.

[0003] After the municipal solid waste incinerator ash is crushed, it is transported to other workstations via other conveyor tracks. When the conveyor tracks become blocked or affect normal transport, a gate plate needs to be installed at the discharge point of the crushing process to temporarily prevent incinerator ash from entering the conveyor track surface. To close the conveyor channel with the gate plate, it needs to be manually moved downwards, and then moved upwards again after normal transport is restored to ensure the correctness and smoothness of the entire workflow. However, manually opening or closing the gate plate poses certain operational risks, and there is a possibility that the gate plate cannot be reliably closed due to the excessive weight of the incinerator ash. Therefore, it is essential to optimize the corresponding opening and closing mechanism to improve structural safety and ensure normal operation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model proposes a mechanism for crushing and opening / closing slag from municipal solid waste incineration furnaces.

[0024] Example 1

[0025] Please see Figure 1 The waste incinerator slag crushing and opening / closing mechanism of this utility model includes a conveyor belt 1 disposed above, a receiving hopper 2 disposed below the discharge port of the conveyor belt 1, the bottom of the receiving hopper 2 being connected to the inlet of the crusher 3, and the discharge port of the crusher 3 being connected to the feeding channel 4; the opening / closing mechanism includes a gate plate 5 disposed between the inlet of the crusher 3 and the feeding channel 4 and capable of sliding up and down, the upper part of the gate plate 5 being connected to one end of a support rod 6, the middle part of the support rod 6 being connected to one end of a first steel wire rope 7, the other end of the first steel wire rope 7 being connected to the telescopic end of a telescopic cylinder 8, the middle part of the support rod 6 being connected to the gate plate 5 via a rotational central shaft 9, the support rod 6 being able to rotate around the rotational central shaft 9, the rotation of the support rod 6 pulling the gate plate 5 upward or pushing the gate plate 5 downward.

[0026] Specifically, in this embodiment, the other end of the support rod 6 is provided with a detachable counterweight 10. The counterweight 10 can apply a downward rotational force about the center of the rotation axis 9 to the other end of the support rod 6, so that when the support rod 6 is not subjected to the upward traction force of the first wire rope 7 and the second wire rope 11, the left side of the support rod 6 is downward through the counterweight 10, and correspondingly, the right side of the support rod 6 is upward, that is, the gate plate 5 is lifted upward; the other end of the support rod 6 is rotatably connected to one end of the second wire rope 11, and the other end of the second wire rope 11 is connected to the drive motor 12 to realize the winding or unwinding of the second wire rope 11.

[0027] Preferably, the housing of the telescopic cylinder 8 is fixedly connected to the surface of the crusher 3 via the first bracket 13. The middle part of the first wire rope 7 passes over the first pulley 14, and the included angle of the entire length of the first wire rope 14 is an acute angle. The middle part of the second wire rope 11 passes over the second pulley 15, and the included angle of the entire length of the second wire rope 11 is an obtuse angle. By setting the included angle of the layout shape of the first wire rope 7 to an acute angle and the included angle of the layout shape of the second wire rope 11 to an obtuse angle, a better spatial layout and better force distribution are achieved, and no interference occurs between the operation of the first wire rope 7 and the second wire rope 11.

[0028] Preferably, the support rod 6 of this utility model is provided with a sliding groove hole 61 on the right side, and the gate plate 5 is provided with a slider 51 hinged to the top, and the slider 51 can slide along the sliding groove hole 61.

[0029] Preferably, sliding grooves 52 are provided on both sides of the gate plate 5, and the gate plate 5 can move linearly relative to the sliding grooves 52.

[0030] Please see Figure 1 The working principle of the slag crushing and opening / closing mechanism for municipal solid waste incinerators of this utility model:

[0031] When it is necessary to close the connection between the feed inlet and the feeding channel 4 of the crusher 3, the telescopic cylinder 8 retracts inward, causing the first wire rope 7 to pull the left side of the support rod 6 upward and rotate clockwise about the rotation center axis 9, which means the right side of the support rod 6 swings downward. At this time, the slider 52 in the sliding groove hole 61 can move to the left along the sliding groove hole 61. As the slider 52 moves to the left, the support rod 6 also applies a downward force to the gate plate 5, and the gate plate 5 also moves downward along the sliding groove 52. Since the actual stroke of the telescopic cylinder 8 is relatively short, the gate plate 5 can only close half of the space between the feed inlet and the feeding channel 4 of the crusher 3, thereby reducing the amount of municipal solid waste incinerator ash being transported. When it is necessary to completely close the connection between the feed inlet of crusher 3 and the feeding channel 4, after the telescopic cylinder 8 is at its maximum retraction stroke, the winding end of the drive motor 12 winds up the second wire rope 11. At this time, the left side of the support rod 6 is also pulled upward, causing it to swing clockwise more significantly about the rotation center axis 9. The gate plate 5 is also further pushed downward, ultimately completely closing the connection between the feed inlet of crusher 3 and the feeding channel 4. Therefore, by pulling the first wire rope 7 with the telescopic cylinder 8 to rotate the support rod 6 clockwise, the gate plate 5 partially closes the material flow path. By winding the second wire rope 11 with the drive motor 12, the support rod 6 is further rotated clockwise, and the gate plate 5 completely closes the material flow path. Therefore, it can be applied to different degrees of closure in different production states, and the closure is completely controlled by the mechanical structure, avoiding direct manual operation and greatly improving the safety of the production process.

[0032] When the gate plate 5 needs to open the material flow path, the second wire rope 11 is loosened by the drive motor 12. Due to the gravity of the counterweight 10 on the left side of the support rod 6, the support rod 6 rotates counterclockwise and resets to a certain extent. At this time, the telescopic cylinder does not extend outward, so the gate plate 5 can move upward halfway. Then, by extending the telescopic cylinder 8 outward, the gate plate 5 can move upward to the highest position of its stroke. The counterweight 10 then maintains pressure and stabilizes the support rod, and the connection between the feed inlet of the crusher 3 and the feeding channel 4 is fully opened.

[0033] Example 2

[0034] Please see Figure 2 The present invention differs from embodiment 1 in the following ways: the right side of the support rod 6 is rotatably connected to one end of the intermediate connecting rod 16, and the other end of the intermediate connecting rod 16 is rotatably connected to the gate plate 5.

[0035] Since the support rod 6 in this embodiment can rotate around the rotation center axis 9, its movement trajectory is circular when the right end of the support rod 6 rotates. In order to avoid the connection point between the gate plate 5 and the support rod 6 getting stuck during the rotation of the support rod 6, this embodiment provides an intermediate connecting rod 16 between the right end of the support rod 6 and the gate plate 5. This allows one end of the intermediate connecting rod 16 connected to the gate plate 5 to rotate relative to the support rod 6, and the other end of the intermediate connecting rod 16 connected to the support rod 6 to rotate relative to the gate plate 5, so as to ensure that the gate plate 5 can move upward normally to open the material flow path, or move downward normally to close the material flow path.

[0036] Example 3

[0037] Please see Figure 3 This utility model discloses a crushing device with an opening and closing mechanism, including two conveyor belts 1 symmetrically arranged at the top, and the shells of crushers 3 symmetrically arranged on the left and right sides welded together. The opening and closing mechanisms on both sides are symmetrically arranged. The telescopic cylinder 8 and the drive motor 12 start or stop according to the working current value of the conveying track 17 below the feeding channel.

[0038] In this embodiment, the crusher shells 3 on the left and right sides are welded together, which can effectively reduce the vibration during the crushing process.
