Description

Technical Field

[0001] This utility model belongs to the field of particle breaking technology for explosive granulation materials. Specifically, it relates to a passive particle breaking mechanism for explosive granulation materials. Background Technology

[0002] In the production process of explosives, granulation is a crucial step, directly affecting the physical properties and final performance of the explosives. After granulation, the material often requires further particle size adjustment through a pelletizing process to meet specific application requirements. However, in current production practice, this pelletizing process generally relies on manual operation. While manual pelletizing can meet production needs to some extent, its inherent limitations are becoming increasingly apparent. First, from a production efficiency perspective, the speed and accuracy of manual operation are often limited by individual physical strength and skill levels, resulting in low overall production efficiency and difficulty in meeting the demands of large-scale production. Especially in high-demand, high-standard production fields like explosives, inefficiency directly impacts product supply capacity and market competitiveness.

[0003] Furthermore, explosive raw materials typically contain various chemical components harmful to the human body, such as nitro compounds and heavy metal ions. During manual pellet cutting, operators inevitably come into contact with these harmful substances, and long-term exposure poses a serious threat to their health. Although certain protective measures can be taken, the health risks inherent in manual operation are difficult to completely eliminate.

[0004] In view of the above problems, there is an urgent need for a mechanical device that can replace manual operation to achieve efficient and safe granulation of explosive granulation materials. While ensuring production efficiency, it can effectively reduce the risk of operators coming into contact with harmful substances, thereby comprehensively improving the safety and sustainability of explosive production. Utility Model Content

This solves the problems of low production efficiency and health risks posed by harmful chemicals present in the granulation materials due to the manual pelletizing process in existing technologies. To achieve the above objective, this utility model provides the following technical solution:

Both the pellet breaking component and the vibration device are mounted on the pellet breaking frame. The vibration device drives the pellet breaking component to complete the pellet breaking of the granulation material.

[0007] Furthermore, the particle breaking assembly includes a plurality of breaking rollers; the plurality of breaking rollers are evenly distributed at intervals on one side of the particle breaking frame and are perpendicular to the connecting surface.

[0008] Furthermore, the vibration device is a turbine vibrator, which is fixedly connected to the lower part of the grain breaking frame and located at the center of the grain breaking frame.

[0009] Furthermore, the air inlet of the turbine vibrator is connected to an external air source device, and a silencer is installed on the air outlet.

[0010] Furthermore, the other side of the grain-breaking frame relative to the hinge side is connected to the structural support via a lifting device; the lifting device drives the grain-breaking frame to rotate along the hinge, completing the mutual conversion of the opening direction of the grain-breaking frame from facing obliquely upward to facing obliquely downward.

[0011] Furthermore, the lifting device includes an electric telescopic cylinder; the base of the electric telescopic cylinder is fixedly connected to the structural support, and the end of the telescopic rod of the electric telescopic cylinder contacts the other side of the opposite hinged side of the particle breaking frame.

[0012] Furthermore, the angle between the opening direction of the electric telescopic cylinder driving the particle breaking frame and the horizontal line ranges from 45 degrees to -45 degrees.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0024] Example:

[0025] See attached Figures 1-4 A passive pellet-breaking mechanism for explosive granulation materials, specifically used for the pellet-breaking process after the explosive granulation process, includes a structural support 1 for overall support. A pellet-breaking frame 2 is located at the upper part of the structural support 1. The pellet-breaking frame 2 has an open end, with its bottom surface positioned at different heights on the structural support 1, so that its opening faces upwards. It is used to receive the granulated material output from the granulator outlet in the previous granulation process. The higher side of the bottom surface of the pellet-breaking frame 2 is hinged to the structural support 1, while the other side of its bottom surface directly contacts the structural support 1 by gravity. A corresponding support frame is provided on the structural support 1 to contact the pellet-breaking frame 2. The pellet-breaking frame 2 can rotate around one side of the hinge, so that its open end faces downwards. That is, when the pellet-breaking frame 2 is in the upward-facing position, it receives the granulated material. After pellet breaking by the pellet-breaking assembly and vibration device, the pellet-breaking frame 2 is adjusted to face downwards for the discharge process. Then, the pellet-breaking frame 2 is adjusted again to continuously complete the pellet-breaking process. The preferred pelletizing frame 2 has its upper bottom opening side and lower bottom opening side arranged alternately to ensure that the opening end area is larger and can better receive the pelletized material.

[0026] The pelletizing assembly of this invention specifically includes several crushing rollers 3. The crushing rollers are cylindrical and vertically arranged inside the bottom surface of the pelletizing frame 2. The crushing rollers 3 are evenly spaced and completely cover the inner bottom surface of the pelletizing frame 2. Preferably, to prevent material from sticking to the crushing rollers 3, the materials and surface treatments used in the prior art are preferred in the selection of materials and surface treatment methods for the crushing rollers 3. The pelletizing material enters the pelletizing frame 2 by gravity, and the staggered crushing rollers 3 only initially break up the pelletizing material.

[0027] The vibration device of this invention uses a turbine vibrator 4, preferably positioned at the center of the outer side of the bottom surface of the granulation frame 2. The turbine vibrator 4 comprises a cylinder, turbine blades, a turbine support, and a buffer mechanism. It utilizes compressed air as a power source. When compressed air enters the cylinder, it drives the turbine blades to rotate at high speed. The turbine support transmits the force to the vibrated object, causing it to vibrate. The buffer mechanism mitigates the impact when the turbine blades reach their limit position, protecting the vibrated object from damage. The turbine vibrator 4 is characterized by high power, no lubrication required, and suitability for extreme environments. Its vibration force can be controlled by adjusting the pressure and flow rate of the compressed air. A compressed air source is connected to its inlet 5 to provide power and further reduce noise. A silencer is installed at its outlet 6. The turbine vibrator 4 drives the granulation frame 2 and the internally interlaced crushing rollers 3 to vibrate, thereby achieving a passive granulation effect on the granulated material. In actual operation, the granulation effect under different vibration forces can be repeatedly tested beforehand to adjust the compressed air pressure and flow rate parameters for a more stable granulation effect.

[0028] In a preferred embodiment of this utility model, a lifting device (not shown in the attached drawings) is provided to control the opening orientation of the grain breaking frame 2. The lifting device adopts an electric telescopic cylinder of the prior art, the base of which is fixedly connected to the structural support 1 and located directly below the other side of the bottom surface of the grain breaking frame 2 opposite to the hinge side. The end of the telescopic rod of the electric telescopic cylinder contacts the other side of the bottom surface of the grain breaking frame 2 opposite to the hinge side. By controlling the extension and retraction of the electric telescopic cylinder, the opening of the grain breaking frame 2 is controlled. Preferably, the extension and retraction range of the electric telescopic cylinder is set to ensure that the angle between the opening of the grain breaking frame 2 and the horizontal line is between -45° and 45°, thereby ensuring that the grain breaking frame 2 will not detach from the telescopic rod in the non-fixed connection mode, and can descend with the telescopic rod by its own gravity.

[0029] To reduce wear and noise caused by vibration of the grain breaking frame 2, a rubber pad is provided on the outer side of the bottom surface of the grain breaking frame 2. When it vibrates in contact with the structural support 1 or the telescopic rod of the electric telescopic cylinder, it can reduce noise generation and wear, and effectively extend its service life.

[0030] The structural support 1 of this utility model is provided with four universal wheels at the bottom, which makes it easy for operators to transfer the broken material. The universal wheels are equipped with a self-locking device to prevent slippage when receiving granulated material. The universal wheel structure can be a self-locking structure of existing technology such as snap-on universal wheels.

[0031] The working principle of this utility model is as follows: The operator unlocks the self-locking device of the universal wheel and moves it to the output end of the granulation process, aligning its opening with the opening of the pelletizing frame 2, so that the granulated material is conveyed into the pelletizing frame 2 at an inclined angle. Then, the turbine vibrator 4 is started, and the staggered crushing rollers 3 work together with the vibration force to continuously crush and break the granulated material. After the pelleting is completed, it is moved to the designated position, and the electric telescopic cylinder is started to extend until the opening of the pelletizing frame 2 faces downward. At this time, the turbine vibrator 4 can also be started to assist the discharge of the pelletizing frame 2, making the discharge more thorough.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
