Description

Technical Field

[0001] The utility model relates to the technical field of slag processing devices, in particular to a horizontal axis hammer crusher. Background Art

[0002] Slag powder is a new type of admixture for high-performance concrete. It can greatly improve the strength of cement concrete and formulate ultra-high-strength cement concrete. It can effectively inhibit the alkali-aggregate reaction of cement concrete and significantly improve the alkali-aggregate reaction resistance and durability of cement concrete. At the same time, it can also improve various properties of concrete, such as resistance to seawater erosion, workability, density and impermeability. Before mixing the concrete, the slag needs to be ground into powder to facilitate more thorough mixing with the concrete.

[0003] In the process of processing slag into slag powder, a crusher is required to process large-sized waste into small-sized granular materials. The horizontal-axis hammer crusher is a practical slag crushing machine. The existing horizontal-axis hammer crusher includes a crushing chamber, which is enclosed in a basically cylindrical shell, wherein there is a horizontal rotating shaft, on which a plurality of hammers are mounted. The hammers are arranged radially relative to the rotating shaft, usually in a row parallel to each other. The slag waste is introduced into the crushing chamber through a loading chute, and the rotating shaft is connected to the motor through a transmission device. The power provided by the motor drives the hammers thereon to strike the slag waste, and the impact force generated by the impact crushes the slag waste. In order to facilitate the discharge of the crushed material from the crushing chamber, a suction device is provided below the outlet, which is fluidly connected to the outlet pipe, for sucking the crushed material out of the crushing chamber. However, the slag waste entering the crushing chamber is easily stuck and blocked in the lower space between the entrance of the crushing chamber and the first set of hammers at the entrance under the action of gravity. Since some of the slag waste is stuck and not crushed, the resistance of the crushing operation is increased, resulting in high energy consumption; in addition, the blockage of the slag waste causes significant wear of the first set of hammers as they continuously impact increasingly bulky and thick materials, and the resulting significant overheating; and the blockage of the slag waste may cause blockage of the entrance, which in turn leads to interruption and failure of the crusher's operation. Utility Model Content

DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will further describe the embodiments of the present invention with reference to the accompanying drawings. The following describes a preferred embodiment of the present invention among multiple possible embodiments, which is intended to provide a basic understanding of the present invention, but is not intended to identify the key or decisive elements of the present invention or to limit the scope of protection to be provided.

[0020] refer to Figures 1 to 2 As shown, the utility model provides a horizontal axis hammer mill 10, including a shell 11, the shell 11 is basically cylindrical, and its internal cavity forms a crushing chamber 12. A rotating shaft 13 coaxial with the shell 11 is provided in the crushing chamber 12, and a plurality of hammers 14 are installed on the rotating shaft 13.

[0021] The housing 11 is provided with a material inlet 15 at a first axial end 16 thereof, and a material outlet 17 at a second axial end 18 thereof. The first axial end 16 and the second axial end 18 are opposite ends of the housing 11 .

[0022] In a preferred embodiment, the material inlet 15 and the material outlet 17 are arranged in an area below the rotating shaft 13 .

[0023] The horizontal axis hammer mill 10 includes a drive unit 23 for driving the rotating shaft 13. In a preferred embodiment, the drive unit 23 includes an electric motor (not shown) that is mechanically connected to a drive belt 24, which is mechanically connected to a drive pulley 25 mounted on the rotating shaft 13.

[0024] The horizontal axis hammer mill 10 includes a loading chute 20 connected to the material inlet 15 via an inlet conduit 21 .

[0025] In an embodiment variant not shown in the drawings, the inlet duct 21 is inclined at 40°-45° to promote the rolling of the material toward the comminution chamber 12 .

[0026] The horizontal axis hammer mill 10 further includes a blower 19 for applying a driving force to the material from the material inlet 15 to the material outlet 17. The blower 19 is fluidically connected to the inlet pipe 21 and is located upstream of the loading chute 20. Figure 1 and 2 During operation, the blower 19 generates airflow through the fan, exerting a driving force on the materials entering the pulverizing chamber 12.

[0027] In an embodiment variant not shown in the figures, the blower 19 is arranged directly at the material inlet 15 .

[0028] The horizontal axis hammer mill 10 includes an outlet pipe 22 connected to the material outlet 17 .

[0030] The working principle of the horizontal axis hammer mill 10 is as follows: the slag waste to be processed is fed from the loading chute 20 through the inlet pipe 21 and the material inlet 15 into the crushing chamber 12. Because the blower 19 applies a propulsion force from the material inlet 15 to the material outlet 17, the material entering the crushing chamber 12 will not be blocked in the space below the crushing chamber inlet and the first set of hammers at the inlet, but will be discharged in the direction of the material outlet 17. Then, the material passes through the crushing chamber 12 and is crushed by the hammers 14 driven by the rotating shaft 13. Then, under the action of the suction device, the crushed material is discharged from the crushing chamber 12 through the material outlet 17 and the outlet pipe 22.
