Description

Technical Field

[0001] This utility model relates to the technical field of crushing devices, specifically a reciprocating extrusion crushing device for municipal solid waste incineration slag. Background Technology

[0002] After municipal solid waste is incinerated in an incinerator, ash is produced inside the incinerator. When processing the ash, it needs to be crushed, which requires the use of a crushing device.

[0003] A search revealed a patent, CN212549893U, which discloses a crushing and processing device for large-piece municipal solid waste incineration slag. The device includes a crushing box with a feed inlet at its upper center and a control box fixed to its right end. A first rotating shaft is installed at the upper front side inside the crushing box, and a second rotating shaft is positioned aligned with the rear of the first shaft. Both the first and second rotating shafts are equipped with material-pulling rods, and both have a first gear at their right ends. This invention features a rotating shaft inside the upper part of the crushing box, with material-pulling rods of different lengths on it. These rods can move and feed large pieces of slag onto the crushing shafts for crushing. After crushing, the slag falls between the two crushing shafts for further grinding and is then conveyed by a conveyor shaft. This design not only achieves excellent crushing results but also prevents blockages during transport.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes the crushing of slag from municipal solid waste incinerators using crushing rollers. However, in reality, some slag pieces in the incinerator are quite large and have accumulated hardness over time. Therefore, when crushing larger pieces of slag using crushing rollers, the process is slow and the rollers are prone to jamming or even being damaged. Consequently, there is an urgent need in the art to improve the crushing device in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a reciprocating extrusion and crushing device for municipal solid waste incinerator slag, which improves the efficiency of crushing municipal solid waste incinerator slag.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating extrusion crushing device for municipal solid waste incineration slag, comprising a crushing box, the upper end of which is open and a first conveying device for conveying is provided on its upper side. A fixed crushing plate is fixedly installed on the upper side wall of the crushing box near the first conveying device. A movable crushing plate adapted to the fixed crushing plate is movably connected in the upper horizontal direction of the crushing box. Several crushing ribs are provided on the opposite sides of the fixed crushing plate and the movable crushing plate. A first drive motor is fixedly installed on one side of the crushing box. A first rotating shaft with one end fixedly installed to the output end of the first drive motor is rotatably connected inside the crushing box.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-6 A reciprocating extrusion crushing device for municipal solid waste incineration slag includes a crushing box 1. The upper end of the crushing box 1 is open and a first conveying device 2 is provided on the upper side for conveying. A fixed crushing plate 3 is fixedly installed on the upper side wall of the crushing box 1 near the first conveying device 2. A movable crushing plate 4 adapted to the fixed crushing plate 3 is movably connected in the upper horizontal direction inside the crushing box 1. Several crushing ribs 5 are provided on the opposite sides of the fixed crushing plate 3 and the movable crushing plate 4. A first drive motor 6 is fixedly installed on one side of the crushing box 1. A first rotating shaft 7 is rotatably connected inside the crushing box 1, with one end fixedly installed to the output end of the first drive motor 6. An eccentric rotating shaft 8, which is not concentric with the first rotating shaft 7, is fixedly installed on the side of the first rotating shaft 7 inside the crushing box 1. A hollow column 9 is rotatably connected to the side of the eccentric rotating shaft 8. Several connecting rods 10 are rotatably connected between the side of the hollow column 9 and the side of the movable crushing plate 4. A discharge port 12 is provided on the lower side of the crushing box 1. The movable crushing plate 4 is inclined and a limiting plate 11 penetrating the crushing box 1 is fixedly connected to the side of the movable crushing plate 4.

[0030] Specifically, when it is necessary to crush the ash in the municipal solid waste incinerator, the ash is removed from the incinerator and conveyed to the upper end of the crushing box 1 by the first conveying device 2, which is based on existing known technology. The ash falls between the fixed crushing plate 3 and the movable crushing plate 4. At the same time, the first drive motor 6 is started. The output end of the first drive motor 6 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the eccentric rotating shaft 8 to rotate. The eccentric rotating shaft 8 is not concentric with the first rotating shaft 7. Therefore, when the eccentric rotating shaft 8 drives the hollow column 9 to rotate, it will drive the movable crushing plate 4 to move through the connecting rod 10. When the movable crushing plate 4 moves, it is limited by the limiting plate 11, and the movable crushing plate 4 is inclined. The movable crushing plate 4 moves in a reciprocating manner, squeezing the slag located between the fixed crushing plate 3 and the movable crushing plate 4, and cooperating with the crushing ribs 5 to crush larger pieces of slag. Since the crushing process is a reciprocating squeezing method, and the movable crushing plate 4 is inclined, it can crush larger pieces of slag, and the slag will not get stuck, thereby improving the efficiency of crushing slag from the municipal incinerator, while not easily damaging the crushing components. The crushed slag is discharged through the discharge port 12.

[0031] As a technical optimization of this utility model, two symmetrical crushing rollers 13 are rotatably connected between opposite sides of the lower part of the crushing box 1. The side of the crushing box 1 is provided with a drive unit for driving the two crushing rollers 13 to rotate in opposite directions. The drive unit includes a second drive motor 14 fixedly installed on one side of the crushing box 1. A second rotating shaft 15 extending to the outside is fixedly installed at one end of each of the two crushing rollers 13. A first gear 16 and a second gear 17 that mesh with each other are fixedly installed on the outer side of the two second rotating shafts 15 respectively. The second drive motor 14 drives one of the second rotating shafts 15 to rotate.

[0032] Specifically, larger pieces of slag are crushed by the fixed crushing plate 3 and the movable crushing plate 4 and fall between the two crushing rollers 13. At this time, the second drive motor 14 is started, and the output end of the second drive motor 14 drives one of the second rotating shafts 15 to rotate. The second rotating shaft 15 drives the second gear 17 to rotate, and the second gear 17 drives the first gear 16 to rotate. Both the first gear 16 and the second gear 17 drive the crushing rollers 13 to rotate, and the two crushing rollers 13 rotate in opposite directions, further refining and crushing the slag, improving the quality of the crushed slag. Since the large pieces of slag have been crushed by the fixed crushing plate 3 and the movable crushing plate 4, the crushing rollers 13 are not affected by the large pieces of slag, thereby improving the service life of the crushing rollers 13.

[0033] As a technical optimization of this utility model, the conveyor belt on the first conveying device 2 is hollow, and a second conveying device 18 is provided on one side of the crushing box 1 below the first conveying device 2. The conveying tail end of the second conveying device 18 extends into the crushing box 1 and is located between the fixed crushing plate 3 and the crushing roller 13. Two symmetrical and inverted V-shaped guide plates 25 are fixedly installed between the opposite side walls inside the crushing box 1. The guide plates 25 are adapted to the crushing roller 13 and are located above the crushing roller 13.

[0034] Specifically, the slag is conveyed by the first conveying device 2. Smaller pieces of slag fall through the holes in the conveyor belt of the first conveying device 2 onto the second conveying device 18. The second conveying device 18 directly conveys the smaller pieces of slag between the two crushing rollers 13, and guides them between the two crushing rollers 13 through two inverted V-shaped guide plates 25. Larger pieces of slag are conveyed by the first conveying device 2 to the positions of the fixed crushing plate 3 and the movable crushing plate 4 for crushing, thereby improving the crushing efficiency of the overall crushing device.

[0035] As a technical optimization of this utility model, the side of the crushing rib 5 is fixedly connected with a plug strip 19. Both the fixed crushing plate 3 and the movable crushing plate 4 have several plug grooves 20 that are adapted to the plug strip 19 on one side. The bottom of the plug groove 20 is fixedly connected with an installation rod 21 that passes through the plug strip 19. The upper end of the plug strip 19 is provided with a countersunk groove 24. The upper side of the installation rod 21 is threaded with a limiting nut 22 located in the countersunk groove 24. The opening end of the countersunk groove 24 is threaded with a sealing plate 23.

[0036] Specifically, when the crushing prism 5 is damaged and needs to be replaced, the insertion strip 19 on one side of the new crushing prism 5 is inserted into the insertion groove 20. The insertion strip 19 is sleeved on the side of the mounting rod 21. The limiting nut 22 is threaded to the upper end of the mounting rod 21 to limit the insertion strip 19. The limiting nut 22 is located in the countersunk groove 24. The sealing plate 23 is threaded to the countersunk groove 24 to prevent the slag from causing deformation of the upper end of the mounting rod 21, which would affect the later replacement. This facilitates the replacement of the crushing prism 5, and each crushing prism 5 can be replaced individually. Only the damaged crushing prism 5 is replaced, reducing the overall maintenance cost of the crushing device.
