Description

Technical Field

[0001] This utility model relates to the field of carbide slag composite material mixing technology, specifically a carbide slag composite material mixing and blending device. Background Technology

[0002] Calcium carbide slag is the waste residue mainly composed of calcium hydroxide after the hydrolysis of calcium carbide to obtain acetylene gas. Acetylene is one of the important raw materials in basic organic synthesis industries. The process of producing acetylene from calcium carbide by adding water is simple and mature, and accounts for a large proportion in my country. 1 ton of calcium carbide can produce more than 300 kg of acetylene gas by adding water, and at the same time generate 10 tons of industrial waste liquid with a solid content of about 12%, commonly known as calcium carbide slag slurry. Calcium carbide slag can be used to replace limestone in cement production, produce quicklime for use as a raw material for calcium carbide, produce chemical products, produce building materials, and for environmental remediation, etc.

[0003] For example, patent application number 202322184361.3 discloses a mixing and blending device for calcium carbide slag composite materials. This utility model discloses a mixing and blending device for calcium carbide slag composite materials, including an outer shell. The upper end of the inner wall of the mixing tank is inlaid with water spray holes, and water pumps are connected to both sides of the water spray holes. A water pump is installed on the water pumps. This mixing and blending device for calcium carbide slag composite materials can crush the raw materials through crushing gears and a first rotating motor, and can also perform rolling grinding through rotating counterweights and grinding wheels. It can efficiently crush the raw materials and facilitate more uniform mixing. Moreover, it can perform uniform ring spraying through water pumps and water spray holes, which is more efficient and more convenient to use. However, this mixing and blending device for calcium carbide slag composite materials generates a lot of dust when mixing the crushed materials. Even if water is used to suppress the dust, dust will still overflow from the feed inlet.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a mixing device for calcium carbide slag composite materials. Utility Model Content

[0014] 1. This utility model, through the arrangement of a mixing device body, feeding hopper, crushing gear, PLC controller, air suction box, air suction fan, exhaust pipe, exhaust box, exhaust port, servo motor, rotating rod, and guide vanes, utilizes the air suction fan to adsorb dust generated during material mixing via the air suction box. After filtering the dust, the air is discharged through the exhaust port of the exhaust box, forming an air wall above the feeding hopper.

Detailed Implementation

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

[0023] like Figures 1-3 As shown, a mixing and blending device for carbide slag composite materials includes a mixing device body 1. A PLC controller 103 is provided on the front surface of the mixing device body 1, and a feed hopper 101 is provided on the upper surface of the mixing device body 1. A crushing gear 102 is rotatably installed on the inner surface of the feed hopper 101. The advantage of this arrangement is that the crushing gear 102 can mesh and crush the carbide slag raw material.

[0024] Furthermore, air suction boxes 2 are provided on both sides of the feed hopper 101, and air suction fans 201 are provided on the surface of the air suction boxes 2. The advantage of this arrangement is that, through the air suction fans 201, the dust generated when the mixing device is mixing materials can be adsorbed by the air suction boxes 2. After the dust is filtered, the air is discharged through the exhaust port 204 of the exhaust box 203, forming an air wall above the feed hopper 101. This prevents the dust generated when the raw materials are fed from overflowing from the inside of the feed hopper 101, reduces dust pollution to the working environment, protects the health of operators, and also helps to improve the overall environmental performance of the device.

[0025] Furthermore, an exhaust pipe 202 is provided on the end surface of the intake fan 201, and an exhaust box 203 is provided on the upper outer surface of the exhaust pipe 202. The advantage of this arrangement is that the filtered air can be guided and transported through the exhaust pipe 202.

[0026] Furthermore, an exhaust port 204 is provided on the inner surface of the exhaust box 203, and a servo motor 205 is provided on the front surface of the exhaust box 203. A rotating rod 206 is installed at the output end of the servo motor 205, and a guide vane 207 is provided on the outer surface of the rotating rod 206. The advantage of this setting is that by adjusting the angle of the air wall through the setting of the guide vane 207, it can better adapt to the shape of the feed hopper 101 and the angle of material falling, more effectively blocking dust from spreading outward, improving the dustproof effect, and reducing dust pollution in the working environment.

[0027] like Figures 4-5 As shown, a sliding frame 303 is slidably installed on the inner surface of the air intake box 2, and a magnetic strip 305 is provided on the inner surface of the sliding frame 303. The advantage of this setting is that the sliding frame 303 can be pulled out from the inside of the air intake box 2 by directly pulling it out, and the dust filter plate 304 can be pushed out from the inside of the sliding frame 303 for quick replacement, thus improving the replacement efficiency.

[0028] Furthermore, a dust filter plate 304 is slidably installed on the inner surface of the sliding frame 303, and the dust filter plate 304 and the magnetic strip 305 are magnetically connected. The dust filter plate 304 has a double-layer structure of coarse and fine mesh. The advantage of this setting is that by setting the dust filter plate 304, it can be divided into two layers of coarse filtration and fine filtration, which can improve the air filtration quality, improve the filtration efficiency, and reduce the replacement frequency of the dust filter plate 304.

[0029] Furthermore, the front surface of the sliding frame 303 is provided with a connecting plate 3, and the front surface of the connecting plate 3 is provided with a handle 301. The advantage of this setting is that the dust filter plate 304 can be easily pulled out and replaced by the handle 301.

[0030] Furthermore, a magnetic suction plate 302 is provided on one side surface of the connecting plate 3, and the magnetic suction plate 302 and the air suction box 2 are magnetically connected. The advantage of this setting is that the connection stability between the sliding frame 303 and the air suction box 2 can be improved by setting the magnetic suction plate 302.

[0031] Working principle: When using the carbide slag composite material mixing and blending device, the material first enters the inside of the feed hopper 101 during the mixing and blending operation of the carbide slag composite material. Then, the PLC controller 103 precisely controls the meshing motion of the crushing gear 102 to perform the initial crushing treatment on the material. Subsequently, the crushed material falls smoothly into the main body 1 of the mixing device, and the mixing and blending process is started.

[0032] Dust generated during the mixing process can be controlled by activating the suction fan 201. The negative pressure generated by the suction fan 201 drives the airflow through the suction box 2 to draw in dust-laden air. Dust particles in the air are effectively trapped when passing through the dust filter plate 304. The purified air is then transported to the exhaust box 203 along the exhaust pipe 202. At this time, the servo motor 205 drives the rotating rod 206 to rotate, which can flexibly adjust the deflection angle of the guide vane 207, thereby precisely controlling the direction of airflow. The adjusted airflow forms a directional wind wall around the feed hopper 101. This wind wall interacts with the natural airflow in the feeding area to build an efficient airflow circulation system, significantly enhancing the dust prevention and suppression effect.

[0033] To address the need for replacing the dust filter plate 304 after it becomes saturated with dust, a convenient and quick replacement structure was designed. The operator only needs to pull the handle 301 to move the connecting plate 3 forward. Once the magnetic suction plate 302 disengages from the magnetic attraction of the suction box 2, the sliding frame 303 can be easily pulled out of the suction box 2. At this point, the dust filter plate 304 can be directly pushed out of the sliding frame 303, completing the filter plate replacement operation. This greatly improves the convenience and efficiency of equipment maintenance. This is the working principle of the carbide slag composite material mixing and blending device.
