Description

Technical Field

[0001] This utility model relates to the field of thermal insulation brick production technology, specifically a raw material crushing device for thermal insulation brick production. Background Technology

[0002] Thermal insulation bricks, as an important building material, play a crucial role in building energy conservation. With the increasing global emphasis on energy conservation, emission reduction, and green building, the market demand for thermal insulation bricks continues to grow. They are widely used in exterior wall insulation and heat insulation projects for various buildings, effectively reducing building energy consumption, improving energy efficiency, and meeting the requirements of sustainable development.

[0003] According to announcement number CN 221907524 U, a raw material crushing device for permeable brick production includes a grinding box and a support set at the bottom of the grinding box. The grinding box is provided with a grinding groove, a grinding plate is provided above the grinding groove, and a discharge pipe is provided on the grinding box.

[0004] This device uses a limiting mechanism to restrict the rotation of the baffle plate, thereby blocking the discharge pipe and preventing uncrushed raw materials from entering the discharge pipe. This blockage prevents the discharge pipe from conveying the ground raw materials out of the grinding chamber, affecting the production of permeable bricks. By energizing the exhaust fan and electromagnet, the electromagnet attracts an iron block, which in turn compresses the spring of the baffle block, releasing the baffle plate's restriction. The exhaust fan then rotates the baffle plate using airflow, allowing the powder in the grinding chamber to be discharged from the discharge pipe. After power is cut off, the spring returns to its original position, causing the baffle block to continue restricting the baffle plate and preventing subsequent uncrushed raw materials from entering the discharge pipe and causing blockage. However, this device only has a pulverizing function and lacks a screening process for the pulverized raw materials. This allows the pulverized raw materials to directly enter the next production process, making it impossible to guarantee the consistency of raw material quality. Utility Model Content

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-3 This utility model provides a technical solution: a raw material crushing device for the production of thermal insulation bricks, including a box body 1, a feeding cylinder 2 fixedly connected to the top of the box body 1, a discharging cylinder 3 fixedly connected to the bottom of the box body 1, support legs 4 symmetrically fixedly connected to the bottom of the box body 1, a screening mechanism 5 provided at the bottom right side of the box body 1, and a crushing mechanism 6 provided at the top right side of the box body 1.

[0029] The screening mechanism 5 includes a fixed frame 51, which is fixedly connected to the bottom right side of the housing 1. A first motor 52 is fixedly connected to the right side of the fixed frame 51 near the right side. A crankshaft 53 is fixedly connected to the output end of the first motor 52. Cranks 54 are symmetrically connected to the surface of the crankshaft 53. A hinge frame 55 is hinged to the other end of the two cranks 54. A reciprocating rod 56 is fixedly connected to the left side of the hinge frame 55. Fixed rods 57 are symmetrically fixedly connected to the bottom on both sides of the inner wall of the housing 1. Slider 58 is symmetrically connected to the surface of the two fixed rods 57. A screening plate 59 is fixedly connected to one side of the slider 58.

[0030] The other end of the crankshaft 53 is rotatably connected to the back of the inner wall of the fixed frame 51 near the right side, and the other end of the reciprocating rod 56 is fixedly connected to the right side of the screening plate 59.

[0031] The right side of the housing 1 near the bottom has a hole that matches the reciprocating rod 56, and the surface of the reciprocating rod 56 is penetrated and slidably connected to the hole, so that the reciprocating rod 56 can move stably left and right.

[0032] A groove is provided on the left side of the box 1 near the bottom, and the left end of the screening plate 59 is located in the groove, so that the raw materials that fail to pass the screening are discharged from the groove.

[0033] Example 2

[0034] Please see Figure 4-5 Furthermore, based on Example 1, a crushing mechanism 6 was obtained.

[0035] The crushing mechanism 6 includes a housing 61, which is fixedly connected to the right side of the box 1 near the top. A second motor 62 is fixedly connected to the right side of the housing 61 near the front. A first crushing roller 63 is rotatably connected to the left side of the inner wall of the box 1 near the top of the front. A second crushing roller 64 is rotatably connected to the left side of the inner wall of the box 1 near the top of the back. A first gear 65 is fixedly connected to the surface of the first crushing roller 63 near the right end. A second gear 66 is fixedly connected to the surface of the second crushing roller 64 near the right end.

[0036] Holes matching the first crushing roller 63 and the second crushing roller 64 are provided on the front and rear sides of the right side of the housing 1 near the top, and the surfaces of the first crushing roller 63 and the second crushing roller 64 are respectively penetrated and rotatably connected in the holes.

[0037] The first crushing roller 63 and the second crushing roller 64 are symmetrically distributed front and rear. The first gear 65 meshes with the second gear 66. Both the first gear 65 and the second gear 66 are located inside the housing 61.

[0038] In actual operation, when this device is in use, the raw materials for producing thermal insulation bricks are fed into the device through the feed cylinder 2 fixedly connected to the top of the housing 1. The feed cylinder 2 guides the raw materials to accurately enter the housing 1. The second motor 62 starts, and the output end of the second motor 62 rotates, driving the first crushing roller 63 connected to it to rotate. Since the first crushing roller 63 has a first gear 65 fixedly connected to its surface near the right end, and the second crushing roller 64 has a second gear 66 fixedly connected to its surface near the right end, and the first gear 65 and the second gear 66 mesh, the rotation of the first gear 65 will drive the second gear 66 to rotate in the opposite direction, thus... The second crushing roller 64 rotates in the opposite direction to the first crushing roller 63. When the raw material enters the housing 1 from the feed cylinder 2, it will fall between the two relatively rotating first crushing rollers 63 and second crushing rollers 64. The special structure on the surface of the first crushing rollers 63 and second crushing rollers 64 will exert a squeezing, shearing and grinding effect on the raw material, breaking large pieces of raw material into smaller particles. The first gear 65 and the second gear 66 are both located inside the housing 61. The housing 61 protects the gears and prevents dust, impurities and other contaminants from entering the gear meshing parts and affecting the normal transmission of the gears, ensuring that the crushing mechanism 6 can operate continuously and stably.

[0039] The crushed raw material falls onto the screening plate 59 at the bottom of the housing 1. At this time, the first motor 52 in the screening mechanism 5 at the bottom right side of the device starts, and the output end of the first motor 52 drives the crankshaft 53 to rotate. The other end of the crankshaft 53 is rotatably connected to the back of the inner wall of the fixed frame 51 near the right side, ensuring the stability of the crankshaft 53's rotation. The surface of the crankshaft 53 is symmetrically connected to cranks 54, and the rotation of the crankshaft 53 will cause the cranks 54 to make circular motion. The other ends of the two cranks 54 are hinged to a hinge frame 55. The circular motion of the cranks 54 is converted into the left and right reciprocating motion of the hinge frame 55 through the hinge frame 55. The left side of the hinge frame 55 is fixedly connected to a reciprocating rod 56, and the other end of the reciprocating rod 56 is fixedly connected to the right side of the screening plate 59. The right side of the housing 1 near the bottom has a hole that matches the reciprocating rod 56. The surface of the reciprocating rod 56 passes through and slides left and right in the hole, so that the hinge... The reciprocating motion of the receiving frame 55 can be transmitted to the screening plate 59 through the reciprocating rod 56, causing the screening plate 59 to reciprocate left and right. During the reciprocating motion of the screening plate 59, fine raw materials with the required particle size will fall through the holes on the screening plate 59 and finally be discharged from the discharge cylinder 3 fixedly connected to the bottom of the box 1, and enter the next production stage. A groove is opened on the left side of the box 1 near the bottom, and the left end of the screening plate 59 is located in the groove. Larger particles that do not meet the required particle size will gradually move to the left during the reciprocating motion of the screening plate 59 and eventually be discharged from the device from the groove. These unqualified raw materials can be crushed again to improve the utilization rate of raw materials.
