Description

Technical Field

[0001] This utility model relates to the field of low-carbon cementitious material production technology, specifically to a high-efficiency grinding equipment for the production of low-carbon cementitious materials. Background Technology

[0002] Low-carbon cementitious materials are a new type of environmentally friendly building material designed to replace traditional silicate cement, thereby reducing energy consumption and carbon emissions. These materials can utilize various industrial solid wastes as raw materials, such as tailings, slag, steel slag, desulfurized gypsum, and fly ash. These raw materials undergo mechanical processing, such as crushing to an average particle size of less than 3 μm, to distort the crystal lattice on the material surface. Then, activators are used to stimulate their chemical activity, thus producing low-carbon cementitious materials.

[0003] Existing equipment cannot accurately achieve the required grinding precision when grinding raw materials, and requires an additional vibration mechanism to assist in screening raw materials to achieve the required precision. The vibration mechanism will affect the grinding equipment and also increase the processing energy consumption.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a high-efficiency grinding equipment for the production of low-carbon cementitious materials, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency grinding equipment for the production of low-carbon cementitious materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency grinding equipment for the production of low-carbon cementitious materials, comprising a grinding box and a side collection box. The grinding box is equipped with a crushing component inside, a gear transmission housing is provided on the top of the grinding box, and a counterweight base is provided on the bottom of the grinding box. Side screening plates are embedded on both sides inside the grinding box, and side collection boxes are provided on both sides outside the grinding box. Arc-shaped slots are provided on the inner side of the side collection boxes. The side collection boxes and the side screening plates are positioned to cooperate with each other. Discharge troughs are provided on the bottom of the outer sides of the side collection boxes on both sides. A discharge port is provided on one side of the bottom wall of the grinding box, and a feed inlet is provided on one side of the top wall of the grinding box.

[0007] The crushing assembly includes a first transmission rod, a second transmission rod, a first crushing wheel, and a second crushing wheel. The first transmission rod is shaft-connected to one side of the bottom of the gear transmission housing, and the second transmission rod is shaft-connected to the other side of the bottom of the gear transmission housing. The first crushing wheel is arranged and sleeved on the outer wall of the first transmission rod, and the second crushing wheel is arranged and sleeved on the outer wall of the second transmission rod. The positions of the multiple sets of first crushing wheels and second crushing wheels are staggered.

[0008] Furthermore, the grinding box and the side screening plate are connected in a detachable structural manner.

[0009] Furthermore, the grinding box and the side screening plate are fixedly connected by bolts.

[0010] Furthermore, the side screening plate is generally arranged in an arc shape, and the dimensions of the side screening plate and the grinding box are matched.

[0011] Furthermore, the gear transmission housing forms a transmission structure with the first transmission rod and the second transmission rod, and the first transmission rod and the second transmission rod are driven to rotate in opposite directions, with the first transmission rod and the second transmission rod arranged vertically parallel.

[0012] Furthermore, the side collection box is connected to the grinding box through an arc-shaped slot, and the side collection box and the side screening plate form a wrapping connection.

[0013] This utility model provides a high-efficiency grinding equipment for the production of low-carbon cementitious materials, which has the following beneficial effects:

[0014] 1. This utility model uses multiple sets of staggered first and second crushing wheels as a grinding component for low-carbon cementitious materials. The relative rotation of the first and second crushing wheels can drive the input low-carbon cementitious material substrate to rotate, thereby breaking down and grinding the raw material in the grinding box.

[0015] The grinding box has side screening plates on both sides of its arc shape. The side screening plates have screening holes, which allow raw materials that have reached the screening accuracy to pass through the side screening plates and enter the side collection box on the outside when grinding is carried out on the inside. This completes the screening and separation operation, and the grinding and screening processes are carried out simultaneously, which can greatly improve the processing efficiency.

[0016] 2. In this utility model, the grinding box and the side screening plate are connected in a detachable manner, which allows for the pre-replacement of side screening plates with different screening apertures as needed, thereby better meeting the screening and separation requirements. The side collection box set on the outside is also installed in a detachable manner, and the screened raw materials can be discharged through the discharge chute set at the bottom of the side collection box.

[0017] The side screening plate can also be inserted into the gap between the grinding box and the side collection box by plugging and unplugging. The plug-and-unplug detachable method improves the replacement efficiency of the side screening plate. The limit of the grinding box and the side collection box can also be used to ensure the stable installation of the side screening plate. The control logic is simple and the equipment has high reliability and stability. Attached Figure Description

The grinding box 1 is equipped with a crushing component 8 inside, a gear transmission housing 2 is provided on the top of the grinding box 1, and a counterweight base 4 is provided on the bottom of the grinding box 1. Side screening plates 101 are embedded on both sides inside the grinding box 1, and side collection boxes 3 are provided on both sides outside the grinding box 1. An arc-shaped slot 301 is opened on the inner side of the side collection box 3. The side collection box 3 and the side screening plates 101 are positioned to cooperate with each other. A discharge chute 6 is opened on the bottom of the outer side of the two side collection boxes 3. A discharge port 7 is provided on one side of the bottom wall of the grinding box 1, and a feed inlet 5 is provided on one side of the top wall of the grinding box 1.

[0025] The crushing assembly 8 includes a first transmission rod 801, a second transmission rod 802, a first crushing wheel 803, and a second crushing wheel 804. The first transmission rod 801 is shaft-connected to one side of the bottom of the gear transmission housing 2, and the second transmission rod 802 is shaft-connected to the other side of the bottom of the gear transmission housing 2. The first crushing wheel 803 is arranged and sleeved on the outer wall of the first transmission rod 801, and the second crushing wheel 804 is arranged and sleeved on the outer wall of the second transmission rod 802. The positions of the multiple sets of first crushing wheels 803 and second crushing wheels 804 are staggered. The grinding box 1 and the side screening plate 101 are connected by a detachable structure. The grinding box 1 and the side screening plate 101 are fixedly connected by bolts; the side screening plate 101 is generally arc-shaped, and the side screening plate 101 and the grinding box 1 are sized to match each other; the gear transmission housing 2 forms a transmission structure with the first transmission rod 801 and the second transmission rod 802, and the first transmission rod 801 and the second transmission rod 802 are driven to rotate in opposite directions, and the first transmission rod 801 and the second transmission rod 802 are arranged vertically parallel; the side collection box 3 is connected to the grinding box 1 through the arc-shaped slot 301, and the side collection box 3 and the side screening plate 101 form a wrapping connection.

[0026] Multiple sets of staggered first crushing wheels 803 and second crushing wheels 804 are used as grinding components for low-carbon cementitious materials. The relative rotation of the first crushing wheels 803 and the second crushing wheels 804 can drive the input low-carbon cementitious material substrate to rotate, thereby dispersing and grinding the raw material in the grinding box 1.

[0027] The grinding box 1 has side screening plates 101 on both sides of its arc shape. The side screening plates 101 are equipped with screening holes, which allow the raw materials that have reached the screening accuracy to pass through the side screening plates 101 and enter the side collection box 3 on the outside when grinding is carried out on the inside, so as to complete the screening and separation operation. This allows the grinding and screening processes to be carried out simultaneously, which can greatly improve the processing efficiency.

[0028] The grinding box 1 and the side screening plate 101 are connected in a detachable manner, and the side screening plate 101 with different screening apertures can be replaced in advance as needed to better meet the screening and separation requirements. The side collection box 3 set on the outside is also installed in a detachable manner, and the screened raw materials can be discharged through the discharge chute 6 set at the bottom of the side collection box 3.

[0029] The side screening plate 101 can also be inserted into the gap between the grinding box 1 and the side collection box 3 by means of plugging and unplugging.

The limiting of the grinding box 1 and the side collection box 3 can also be used to ensure the stable installation of the side screening plate 101. The control logic is simple and the equipment has high reliability and stability.

[0030] Working principle: For this type of high-efficiency grinding equipment for the production of low-carbon cementitious materials, the gear transmission housing 2 connected to the top of the grinding chamber 1 first drives the motor and gear assembly inside the gear transmission housing 2, thereby causing the first transmission rod 801 and the second transmission rod 802 at the bottom to rotate relative to each other. Then, the low-carbon cementitious material substrate to be processed is put into the feed inlet 5 at the top. Then, the first crushing wheel 803 and the second crushing wheel 804 inside drive the low-carbon cementitious material substrate to rotate, gradually grinding the low-carbon cementitious material substrate. During the grinding process, the raw material that reaches the screening accuracy passes through the side screening plate 101 and enters the side collection box 3 on the outside to complete the screening and separation operation. At the same time, the screened raw material can be collected through the discharge chute 6 at the bottom of the side collection box 3. After the screening operation is completed, the remaining raw material can be collected through the discharge port 7 at the bottom of the grinding chamber 1.
