Description

Technical Field

[0001] This utility model relates to the field of coal gangue broken brick processing technology, and more specifically, it relates to an environmentally friendly coal gangue broken brick recycling crushing device. Background Technology

[0002] Coal gangue sintered bricks are building materials produced using a sintering process that uses coal gangue as a binder. Coal gangue bricks exhibit superior compressive strength, flexural strength, acid resistance, and alkali resistance compared to clay bricks. From a cost perspective, no watering is required before bricklaying and plastering, saving on water and labor costs. Furthermore, due to their higher hardness, the bricks experience less damage during transportation compared to clay bricks.

[0003] Currently, in the building materials production market, the crushing of raw materials such as coal gangue is typically carried out using two motor-driven crushing rollers fixed at the output end. This production method is characterized by high efficiency and stability, and can quickly crush raw materials such as coal gangue into the required particle size to meet the requirements of subsequent production processes.

[0004] However, since it is inconvenient to replace the fixed crushing rollers, after a long period of use, the surface of the crushing rollers will inevitably wear down, making the surface rough and uneven. This wear affects the uniformity of subsequent crushing and the overall service life of the device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an environmentally friendly coal gangue crushing device for recycling broken bricks.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0026] Please see Figure 1-5 Structural diagram; the present invention provides the following technical solution:

[0027] Specifically, this refers to an environmentally friendly coal gangue broken brick recycling crushing device, including a bottom silo 1. The bottom silo 1 has a spacious interior, capable of holding a certain amount of coal gangue broken bricks, providing sufficient material storage space for subsequent crushing operations. A feed frame 2 is fixedly installed through the top of the bottom silo 1. Operators only need to place the coal gangue broken bricks directly on top of the feed frame 2, and the material will naturally slide into the device. A pick-up and drop-off door 3 is movably connected to the front of the feed frame 2 via a hinge, which facilitates the picking and dropping of the crushing roller 6. A pair of cross shafts 4 are rotatably connected to the vertical inner wall of the feed frame 2. A motor 5 is fixedly connected to the feed frame 2 to drive the cross shafts 4 to rotate. The crushing roller 6 is slidably sleeved on the outer wall end face of the cross shafts 4. In actual operation, when the motor 5 drives the cross shafts 4 to rotate, it drives the crushing roller 6 to rotate and crush the material.

[0028] Also includes:

[0029] Limiting component, the limiting component is used to limit and fix the crushing roller 6.

[0030] The limiting component includes a mounting groove 41 on the front of the cross shaft 4. A cross plate 42 is fixedly connected in the mounting groove 41. The cross plate 42 has four sliding openings 43. The sliding openings 43 are designed to ensure the smooth sliding of the T-shaped plate 44, and the T-shape of the T-shaped plate 44 is designed to prevent it from falling out of the sliding openings 43 to a certain extent. The T-shaped plate 44 is slidably connected in the sliding openings 43. A spring 45 is fixedly connected in the sliding openings 43, and one end of the spring 45 is fixedly connected to the T-shaped plate 44. An insert plate 46 is fixedly connected to the T-shaped plate 44.

[0031] The four sliding ports 43 are arranged in a circular array, and the insertion plate 46 is located at the end of the spring 45 near the crushing roller 6. This arrangement is to make the insertion force of the insertion plate 46 more even.

[0032] The cross shaft 4 has an insertion port 47 for easy insertion of the insertion plate 46, the crushing roller 6 has a slot 62 for easy insertion of the insertion plate 46, and the crushing roller 6 has a cross opening 61 for easy sliding on the cross shaft 4.

[0033] A pair of inclined plates 9 are fixedly connected to the vertical inner wall of the top of the feed frame 2, and the inclined plates 9 are positioned above the crushing roller 6. The inclined plates 9 are designed to ensure that the material falls stably vertically and is crushed by the crushing roller 6.

[0034] A transparent observation window 8 is embedded and fixedly installed on the front of the bottom silo 1, allowing operators to easily observe the storage status of materials inside the bottom silo 1. A side door 7 is movably connected to the vertical side wall of the bottom silo 1 via hinges. The side door 7 allows operators to easily remove the crushed material.

[0035] The working principle of the environmentally friendly coal gangue crushing device for recycling broken bricks provided by this utility model is as follows:

[0036] When replacing the crushing roller 6, the operator first opens the pick-up and drop-off door 3, pulls the four T-shaped plates 44 to move the insert plate 46 out of the slot 62 and the insertion port 47 in sequence, and at this time the spring 45 is compressed.

[0037] Then, the crushing roller 6 is removed horizontally from the cross shaft 4, and the removed crushing roller 6 is taken out from the inside of the feed frame 2 for replacement.

[0038] When the crushing roller 6 is installed, the crushing roller 6 is slidably sleeved on the cross shaft 4. Press the insert plate 46 that has passed through the insertion port 47 (because of the elastic force of the spring 45, the insert plate 46 is initially in the insertion port 47). After pressing, the spring 45 is compressed. At this time, the crushing roller 6 can be smoothly installed horizontally. When the crushing roller 6 moves to the slot 62 and corresponds to the insert plate 46, the insert plate 46 is inserted into the slot 62 under the elastic force of the spring 45, thereby realizing the locking installation of the crushing roller 6.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
