Description

Technical Field

[0001] This utility model belongs to the technical field of emulsion explosive production equipment, specifically a cooling and solidification device for emulsion explosive production. Background Technology

[0002] In the industrial production of emulsion explosives, the cooling and solidification process plays a decisive role in product quality and production efficiency. Traditional cooling systems often rely on manual experience to set cooling times, lacking precise timing and counting devices. This results in uneven cooling levels between different batches of products, making it difficult to meet stringent quality standards.

[0003] In addition, most production processes are segmented, and there is a lack of automated connection in material conveying, cooling, unloading and other links. Frequent manual intervention not only increases labor intensity, but also easily affects production stability due to operational errors, making it difficult to achieve continuous and large-scale production. Moreover, the parameter adjustment flexibility of traditional equipment is insufficient, making it difficult to quickly adapt the cooling process according to different formulas and specifications of emulsion explosives, which limits the versatility of the production line. Summary of the Invention

[0004] To address the problems existing in the background technology, this utility model provides a cooling and solidification device for the production of emulsion explosives.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling and solidification device for the production of emulsion explosives, comprising a belt conveyor, a concave frame, a fixed column, a slider, a flip plate, a bellows, a connecting frame, a rubber roller, a baffle plate, an infrared counter, a control mechanism, a lifting mechanism, and two protective plates;

[0006] The belt conveyor has guard plates on both sides. The concave frame is fixedly connected to two guard plates. One guard plate is fixedly connected to a fixed column. The fixed column is fixedly connected to a lifting mechanism. The lifting mechanism is hinged to a slider. The flip plate has a chute and a placement opening. The slider is slidably connected to the chute. A bellows is fixed inside the placement opening. One end of the flip plate is hinged to the concave frame. The other end of the flip plate is fixedly connected to a connecting frame. The connecting frame is rotatably connected to a rubber roller. The rubber roller is used in conjunction with the belt conveyor. A wind baffle is fixed to the inner wall of the flip plate. The wind baffle is correspondingly arranged with the bellows. An infrared counter is provided on the outer wall of the wind baffle. The infrared counter and the lifting mechanism are both signal-connected to the control mechanism.

[0007] The lifting mechanism includes a cylinder, an air source, a solenoid valve controller, and a floating joint.

[0008] The cylinder body is fixedly connected to the side wall of the fixed column, the cylinder is fixedly connected to the air source, the air source is electrically connected to the solenoid valve controller, the solenoid valve controller is signal connected to the control mechanism, the cylinder extension end is fixedly connected to the floating joint, and the floating joint is hinged to the slider.

[0009] The control mechanism includes a PLC controller and a computer;

[0010] The computer is connected to the PLC controller and the infrared counter signal respectively, and the PLC controller is connected to the solenoid valve controller and the belt conveyor signal respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Precise control of the cooling process: By setting the cooling time and the number of interceptions per batch through a computer, the PLC controller precisely controls the start and stop of the belt conveyor, the action of the cylinder, and the start of the bellows, achieving precise control of the cooling and solidification process of the emulsion explosive. This ensures that each production link is carried out according to the preset parameters, improving product quality and production stability.

[0013] 2. Avoid material damage: The material is intercepted by a gentle contact between the rubber roller and the conveyor belt. The elasticity and rotation characteristics of the rubber roller prevent hard compression of the emulsion explosive during the interception process, effectively preventing the emulsion explosive from deforming or causing danger due to compression, thus ensuring production safety.

[0014] 3. Improved cooling efficiency: The high-pressure airflow generated by the air box forms a locally enclosed cooling space under the guidance of the baffle plate, which restricts the airflow to the area between the inner wall of the flap and the material. This guides the airflow to evenly cover the surface of the accumulated material, preventing airflow diffusion and allowing the cooling airflow to act more effectively on the material, greatly improving cooling efficiency and shortening the production cycle.

[0015] 4. Achieve continuous production: The infrared counter monitors the amount of material passing through in real time. When the set quantity is reached, a series of operations are automatically triggered, including stopping the belt conveyor, starting the cooling timer, opening the cooling area and restarting the belt conveyor after cooling is completed. This realizes a cyclical process of "conveyance → interception counting → cooling timer → unloading", which makes the entire production process continuous and efficient, and improves production efficiency.

[0016] 5. Flexible and adjustable operation: The cooling time and the number of interceptions per burst can be flexibly adjusted according to the characteristics of the emulsion explosive and the requirements of the production process. It can adapt to the production needs of different types and specifications of emulsion explosives and has strong versatility and adaptability.

[0017] 6. High degree of automation: The entire device is automatically controlled through a control mechanism, which reduces manual intervention, lowers labor intensity, reduces the impact of human factors on the production process, and improves the level of automation and convenience of production management.

[0018] In summary, this utility model possesses the advantages of precise control of the cooling process, ensuring the quality and production stability of emulsion explosives; gentle interception of materials by rubber rollers to avoid damage and ensure production safety; improved cooling efficiency and shortened cycle time through the combination of bellows and baffles; continuous production and increased efficiency through infrared counters; flexible and adjustable cooling parameters to adapt to different production needs; and high degree of automation, reducing manual intervention, lowering labor intensity, and improving production automation and management convenience.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] This embodiment describes a cooling and solidification device for the production of emulsion explosives, including a belt conveyor 1, a concave frame 3, a fixed column 4, a slider 9, a flip plate 10, a bellows 11, a connecting frame 12, a rubber roller 13, a wind deflector 14, an infrared counter 15, a control mechanism, a lifting mechanism, and two guard plates 2.

[0024] The belt conveyor 1 has guard plates 2 on both sides. The concave frame 3 is fixedly connected to the two guard plates 2. One guard plate 2 is fixedly connected to the fixed column 4. The fixed column 4 is fixedly connected to the lifting mechanism. The lifting mechanism is hinged to the slider 9. The flip plate 10 has a sliding groove and a placement opening. The slider 9 is slidably connected to the sliding groove. A bellows 11 is fixed in the placement opening. One end of the flip plate 10 is hinged to the concave frame 3. The other end of the flip plate 10 is fixedly connected to the connecting frame 12. The connecting frame 12 is rotatably connected to the rubber roller 13. The rubber roller 13 is used in conjunction with the belt conveyor 1. A wind baffle 14 is fixed on the inner wall of the flip plate 10. The wind baffle 14 is correspondingly set to the bellows 11. An infrared counter 15 is provided on the outer wall of the wind baffle 14. The infrared counter 15 and the lifting mechanism are both signal connected to the control mechanism.

[0025] The lifting mechanism includes a cylinder 5, an air source 6, a solenoid valve controller 7, and a floating joint 8.

[0026] The cylinder body of the cylinder 5 is fixedly connected to the side wall of the fixed column 4. The cylinder 5 is connected and fixedly connected to the air source 6. The air source 6 is electrically connected to the solenoid valve controller 7. The solenoid valve controller 7 is signal connected to the control mechanism. The telescopic end of the cylinder 5 is fixedly connected to the floating joint 8. The floating joint 8 is hinged to the slider 9.

[0027] The control mechanism includes a PLC controller and a computer;

[0028] The computer is connected to the PLC controller and the infrared counter 15 respectively. The PLC controller is connected to the solenoid valve controller 7 and the belt conveyor 1 respectively.

[0029] When using this invention, the emulsion explosive is placed on the conveyor belt of the belt conveyor 1 (existing technology) at equal intervals and in batches, either manually or using a front-end conveying device. The spacing must be set to ensure that the infrared counter 15 can accurately identify the passage of individual materials. The operator sets the cooling time (e.g., preset to T minutes, the T value can be flexibly adjusted according to the characteristics of the emulsion explosive and production process requirements) and the number of materials intercepted at one time (e.g., 5 materials) via computer, and sends a start command. The PLC controller triggers two actions: starting the belt conveyor 1, the material moves with the conveyor belt towards the flip plate 10; and controlling the solenoid valve. When device 7 turns on air source 6, it supplies air to cylinder 5. The cylinder's telescopic end pushes slider 9 down the slide groove of flap 10 through floating joint 8, causing flap 10 to rotate downward around the hinge point of concave frame 3 until rubber roller 13 gently contacts the conveyor belt. Utilizing the elastic material and rotational characteristics of rubber roller 13, it avoids hard compression that could deform or endanger the emulsion explosive when intercepting materials, forming a physical barrier to the materials. This causes the materials to accumulate between flap 10 and the conveyor belt to a set number (e.g., 5). The bellows 11 is then activated by an external power supply, and high-pressure airflow is sprayed through the bellows outlet towards the baffle 14. The baffle 14 guides the airflow. The function is to confine the airflow to the area between the inner wall of the flap 10 and the material, forming a locally enclosed cooling space to prevent airflow diffusion and guide the airflow to evenly cover the surface of the accumulated material, thereby improving cooling efficiency. The infrared counter 15 monitors the number of materials passing through its sensing area in real time. When the fifth piece of material is detected to reach the vicinity of the baffle 14, a signal is sent to the computer. The computer responds by sending an instruction to the PLC controller to stop the belt conveyor 1, preventing subsequent materials from entering the cooling area, and starting an internal countdown (preset time T minutes) to begin timing the cooling cycle. When the computer countdown reaches the preset time... At time T minutes, the following operations are triggered by the PLC controller: the solenoid valve controller 7 switches the air source 6 to retract the cylinder 5, causing the floating joint 8 and slider 9 to move upward, the flap 10 to rotate upward around the hinge point, the rubber roller 13 moves away from the conveyor belt, the cooling area is opened, and the belt conveyor 1 is restarted. The cooled and solidified material continues to be conveyed forward with the conveyor belt to enter the next process (such as packaging or storage). When the subsequent material passes through the infrared counter 15, the counter sends a signal to the computer again. The computer repeats the cycle of "conveyance → interception counting → cooling timing → unloading" to achieve continuous production.
