Description

Technical Field

[0001] This utility model relates to the field of mixed crushing technology, specifically a mixed crushing device for the production of solid waste mineral admixtures. Background Technology

[0002] In the processing of solid waste mineral admixtures, the mixing and crushing device is a key piece of equipment, undertaking the important task of pre-treating various types of solid waste.

[0003] Traditional mixing and crushing devices typically employ a single fixed or integrally open / closed feed inlet. This design lacks the ability to control material feeding in stages, leading to continuous leakage of dust generated during crushing through the open inlet. This not only wastes raw materials but also pollutes the working environment, and the flying fragments pose a health hazard to operators. Therefore, those skilled in the art have developed a mixing and crushing device for producing solid waste mineral admixtures to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing and crushing device for the production of solid waste mineral admixtures. This solves the problem that traditional mixing and crushing devices typically use a single fixed or integral opening and closing structure for the feed inlet. This structure makes it impossible to control the material feeding in stages during the feeding process, resulting in dust generated during the material crushing process continuously leaking out through the open feed inlet. This not only wastes raw materials but also pollutes the working environment, and the splashed fragments can harm the health of operators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and crushing device for producing solid waste mineral admixtures, comprising a feed pipe, a crushing unit connected to the lower part of the feed pipe, a crushing roller assembly disposed within the crushing unit, a stirring unit connected to the lower part of the crushing unit, a first slot provided in the upper end port of the feed pipe, a second slot provided in the lower end port of the feed pipe, a movable groove provided on one side of the feed pipe, an upper cover plate provided in the upper end of the feed pipe, a first connecting rod provided on one side of the upper cover plate, a lower cover plate provided in the lower end of the feed pipe, a second connecting rod provided on one side of the lower cover plate, a limit sleeve provided in the movable groove, and a stepper motor installed on the outer wall of the feed pipe.

[0006] Preferably, the output end of the stepper motor facing the movable slot is driven to be connected to the limiting sleeve.

[0007] Preferably, the upper cover plate is slidably inserted into the first slot, and the lower cover plate is slidably inserted into the second slot.

[0008] Preferably, a first connector is installed on the bottom side of one end of the upper cover plate that is in the movable groove, and the first connector is rotatably connected to the first connecting rod. A second connector is installed on the upper side of one end of the lower cover plate that is in the movable groove, and the second connector is rotatably connected to the second connecting rod.

[0009] Preferably, the two ends of the limiting sleeve are slidably inserted into the first connecting rod and the second connecting rod, respectively. When the stepper motor drives the limiting sleeve to rotate, the limiting sleeve drives the first connecting rod and the second connecting rod to rotate, so that when the upper cover is opened, the lower cover is closed, and when the lower cover is opened, the upper cover is closed.

[0010] Compared with the prior art, this utility model provides a mixing and crushing device for the production of solid waste mineral admixtures, which has the following beneficial effects:

[0011] By designing a first slot and a second slot, along with corresponding upper and lower cover plates, distributed vertically in the feed pipe, and coordinating with the linkage mechanism inside the movable slot and the limit sleeve driven by the stepper motor, the alternating opening and closing function of the upper and lower cover plates is realized. This design allows the material to be temporarily stored in the lower cover plate during the feeding stage. After feeding is completed, the material is accurately fed into the crushing roller group through the opening of the lower cover plate. At the same time, the upper cover plate automatically closes to form a closed space. This structure not only avoids the problem of splashing caused by direct impact of material during crushing, but also effectively blocks dust from escaping, significantly improving the working environment while ensuring crushing efficiency.

[0018] The output end of the stepper motor 6, facing the movable slot 103, is driven and connected to the limiting sleeve 7. The upper cover plate 4 is slidably inserted into the first slot 101, and the lower cover plate 5 is slidably inserted into the second slot 102. A first connector 401 is installed on the bottom side of one end of the upper cover plate 4 within the movable slot 103. The first connector 401 is rotatably connected to the first connecting rod 402. A second connector 501 is installed on the upper side of one end of the lower cover plate 5 within the movable slot 103. The second connector 501 is rotatably connected to the second connecting rod 502. The two ends of the limiting sleeve 7 are slidably inserted into the first connecting rod 402 and the second connecting rod 502, respectively. When the stepper motor 6 drives the limiting sleeve 7 to rotate, the limiting sleeve 7 drives the first connecting rod 402 and the second connecting rod 502 to rotate, so that when the upper cover plate 4 is opened, the lower cover plate 5 is closed, and when the lower cover plate 5 is opened, the upper cover plate 4 is closed.

[0019] The working principle of this device is as follows: The mixing and crushing device for the production of solid waste mineral admixtures consists of a feed pipe 1, a crushing unit 2 and a stirring unit 3. The feed pipe 1 is installed on the upper side of the crushing unit 2, and the stirring unit 3 is installed on the bottom side of the crushing unit 2. A crushing roller group 201 is installed inside the crushing unit 2.

[0020] A first slot 101 is provided in the upper end of the feed pipe 1, and a second slot 102 is provided in the lower end of the feed pipe 1. An upper cover plate 4 is inserted into the first slot 101, and a lower cover plate 5 is inserted into the second slot 102. A movable groove 103 is provided in the side wall of the feed pipe 1, and the movable groove 103 communicates with the first slot 101 and the second slot 102. A first connector 401 is installed on the bottom side of the upper cover plate 4 within the movable groove 103, and a first connecting rod 402 is rotatably connected to the first connector 401. A second connector 501 is installed on the upper side of the lower cover plate 5 within the movable groove 103, and a second connecting rod 502 is rotatably connected to the second connector 501. A second connecting rod 502 is installed on the outer wall of the feed pipe 1. A stepper motor 6 is provided, and the output end of the stepper motor 6 is driven to connect to a limiting sleeve 7 in the movable groove 103. The two ends of the limiting sleeve 7 are slidably connected to the first connecting rod 402 and the second connecting rod 502, respectively. When the stepper motor 6 drives the limiting sleeve 7 to rotate, the limiting sleeve 7 drives the first connecting rod 402 and the second connecting rod 502 to rotate, so that when the upper cover plate 4 is opened, the lower cover plate 5 is closed, and when the lower cover plate 5 is opened, the upper cover plate 4 is closed. This means that when the feed pipe 1 is fed, the material will first fall onto the lower cover plate 5. After the feeding is completed, the lower cover plate 5 is opened, and the material falls onto the crushing roller group 201 for crushing. At this time, the upper cover plate 4 is closed to seal the feed pipe 1, so as to avoid material splashing during crushing and to prevent dust from flying.
