Description

Technical Field

[0001] This utility model relates to the field of rapid hardening self-flowing material processing, and in particular to a drum screen for removing impurities in rapid hardening self-flowing material production. Background Technology

[0002] Rapid-hardening self-leveling material is a building material with self-leveling, rapid hardening and early strength characteristics. It is widely used in engineering fields such as floor repair, precast component grouting, and rapid construction. During its production process, the raw materials are often mixed with impurities of different particle sizes. If these impurities cannot be effectively removed, they will directly affect the material's fluidity and hardening performance, reducing the quality stability of the final product.

[0003] Therefore, the screening and impurity removal process has become one of the key links to ensure the performance of fast-hardening self-flowing materials. At present, the industry mostly uses drum-type screening devices to complete this process. The drum rotates to make the raw material move inside the drum, and the filter holes in the drum wall are used to separate impurities from qualified raw materials. With the advantages of continuous operation and large processing capacity, it has become the mainstream equipment in the production of fast-hardening self-flowing materials.

[0004] However, conventional drum screen impurity removal devices still have shortcomings in practical applications. Traditional devices are mostly single-layer screening structures, which can only separate impurities of a single particle size. If it is necessary to remove large particles larger than the raw material and small particles smaller than the raw material at the same time, two independent screenings are required, which is troublesome, time-consuming and labor-intensive, resulting in low production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drum screen for removing impurities in the production of fast-hardening self-flowing materials. It aims to improve the problems of conventional drum screens in the prior art, which require two independent screenings to remove impurities of different particle sizes due to their single-layer screening structure, resulting in troublesome operation, time and labor costs, and low production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drum screen for removing impurities in the production of fast-hardening self-flowing materials, comprising a support frame, a motor disposed on the rear surface of the support frame, a rotating shaft fixedly connected to the output shaft of the motor, a support rod fixedly connected to the outer wall of the rotating shaft, a screening component disposed on the outer wall of the support rod, a cleaning component disposed on the inner surface of the support frame, and a feeding bin fixedly connected to the front end of the inner surface of the support frame;

A cleaning roller is fixedly connected to the outer wall of the rotating rod, and a first pulley is fixedly connected to the front end of the outer wall of the rotating rod. A second pulley is connected to the outer wall of the first pulley via a belt drive.

[0010] As a further description of the above technical solution:

[0011] The rotating shaft passes through and is rotatably connected to the inner surface of the support frame.

[0012] As a further description of the above technical solution:

The output shaft of the motor 2 is fixedly connected to a rotating shaft 5. A support rod 6 is fixedly connected to the outer wall of the rotating shaft 5. The rotating shaft 5 and the support rod 6 rotate synchronously. Multiple sets of support rods 6 are arranged in a circular array with the center of the rotating shaft 5 as the origin. A screening component 3 is mounted on the outer wall of the support rod 6.

A cleaning component 4 is mounted on the inner surface of the support frame 1. A feeding bin 7 is fixedly connected to the front end of the inner surface of the support frame 1, and the fast-hardening self-flowing material is added from the feeding bin 7.

[0033] Reference Figure 1 , Figure 2 , Figure 4 The screening assembly 3 includes a second screening cylinder 37, which can screen out impurities larger than the raw material. The inner surface of the second screening cylinder 37 is fixedly connected to the end of the support rod 6 away from the rotating shaft 5. A fixing block 33 is fixedly connected to the outer wall of the second screening cylinder 37. A first screening cylinder 32 is fixedly connected to the end of the fixing block 33 away from the second screening cylinder 37. The fixing block 33 is used to connect the second screening cylinder 37 and the first screening cylinder 32. A fixing ring 31 is fixedly connected to the front end of the inner surface of the first screening cylinder 32. A rotating ring 34 is rotatably connected to the rear surface of the first screening cylinder 32. The centers of the fixing ring 31, the rotating ring 34, the rotating shaft 5, the second screening cylinder 37, and the first screening cylinder 32 are on the same axis. A feeding bin 35 is fixedly connected to the inner surface of the rotating ring 34. A feeding port 36 is opened through the lower surface of the feeding bin 35. A collecting device can be installed at the feeding port 36 to collect the screened raw material.

[0034] Reference Figure 1 , Figure 2 , Figure 4The rotating shaft 5 is rotatably connected to the inner surface of the support frame 1, which provides support for the rotating shaft 5. The front surface of the second screening cylinder 37 is fixedly connected to the rear surface of the fixed ring 31. The rear surface of the second screening cylinder 37 and the front surface of the rotating ring 34 are in contact to ensure a seal and prevent leakage. The inner diameters of the fixed ring 31, the rotating ring 34, and the second screening cylinder 37 are aligned to avoid obstructing impurities and allow the screened impurities to be discharged smoothly. The rear surface of the feeding bin 35 is fixedly connected to the rear end of the inner surface of the support frame 1. The feeding bin 35 and the rotating ring 34 can remain stable, ensuring that the feeding port 36 always faces downward. The outer wall of the second screening cylinder 37 is provided with multiple sets of filter holes, and the outer wall of the first screening cylinder 32 is provided with multiple sets of filter holes. The first filter hole is larger than the second filter hole. Small particles of impurities and raw materials can pass through the first filter hole, while small particles of impurities can pass through the second filter hole. The feeding bin 7 is set in an inclined shape with a higher front and a lower rear.

[0035] Reference Figures 1-3 The cleaning component 4 includes a rotating rod 41, which is rotatably connected to the inner surface of the support frame 1. A cleaning roller 42 is fixedly connected to the outer wall of the rotating rod 41. The cleaning roller 42 and the rotating rod 41 rotate synchronously. The outer wall of the cleaning roller 42 is provided with bristles. When rotating, the bristles will strike the first screening cylinder 32, thereby causing the second screening cylinder 37 and the first screening cylinder 32 to vibrate, thus preventing clogging. A first pulley 43 is fixedly connected to the front end of the outer wall of the rotating rod 41. A second pulley 45 is connected to the outer wall of the first pulley 43 via a belt 44. The second pulley 45 is fixedly connected to the front end of the outer wall of the rotating shaft 5.

[0036] Working principle: When using the device, first install the collection device at the discharge port 36, then start the motor 2 to drive the rotating shaft 5 to rotate. The rotating shaft 5 will drive the support rod 6, the second screening cylinder 37, the fixed block 33, the fixed ring 31, the first screening cylinder 32, and the second pulley 45 to rotate synchronously.

[0037] Then, the fast-hardening self-flowing material is poured in from the feeding hopper 7. The fast-hardening self-flowing material will enter the second screening cylinder 37 along the trajectory of the feeding hopper 7. The rotating second screening cylinder 37 will drive the fast-hardening self-flowing material, and qualified raw materials and small particulate impurities in the fast-hardening self-flowing material will pass through the filter hole one. Qualified raw materials and small particulate impurities will fall onto the first screening cylinder 32. The rotating first screening cylinder 32 will cause small particulate impurities to pass through the filter hole two. Under the guidance of the first screening cylinder 32 and the second screening cylinder 37, large particulate impurities will be discharged from the rear opening of the second screening cylinder 37, and small particulate impurities will be discharged from the filter hole two. Qualified raw materials will be collected through the discharge port 36.

[0038] Furthermore, during screening, the rotation of the second pulley 45 will drive the belt 44 to drive the first pulley 43 to rotate synchronously. The first pulley 43 will drive the rotating rod 41 and the cleaning roller 42 to rotate. The rotating cleaning roller 42 will cause the bristles to hit the outer wall of the first screening cylinder 32, thereby causing the first screening cylinder 32 and the second screening cylinder 37 to vibrate slightly. This can prevent impurities from clogging the first and second meshes, ensuring screening quality and stability.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
