Description

Technical Field

[0001] The utility model relates to the technical field of preparation devices, and specifically relates to a preparation device for coal gangue - blended cement. Background Art

[0002] Coal gangue is a solid waste discharged during the coal mining process and coal washing process. It is a dark - gray rock with a lower carbon content and harder than coal, which is associated with the coal seam during the coal - forming process. By heating coal gangue to a high temperature to transform it into clinker, and adding appropriate amounts of lime, aluminate, and other substances to the clinker, and then through processes such as cooling and grinding, cement is obtained.

[0003] During the preparation of coal gangue - blended cement, the crushed coal gangue needs to be stirred and mixed with other materials. Since the crushed coal gangue contains uneven large particles, the entry of large particles into the mixing device will reduce the production quality of the cement. If the amount of large particles reaches a certain level, the quality of the cement will not meet the standard, resulting in waste of raw materials. Therefore, a preparation device for coal gangue - blended cement is proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a preparation device for coal gangue - blended cement to solve the problem of coal gangue particles.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A preparation device for coal gangue - blended cement includes a stirring device for mixing various materials evenly, a stirring motor for driving the stirring blades to rotate, a discharge port, and a feed port. The stirring motor is arranged at the top of the stirring device, the discharge port with a trapezoidal cross - section is arranged at the bottom of the stirring device, the feed port in the shape of a cylindrical pipe is fixedly connected to the top of the stirring device. A second baffle with a T - shaped cross - section is closely attached to one side of the feed port. A rubber ring is fixedly connected to the bottom of the second baffle, and a first baffle is fixedly connected to the other side of the rubber ring. A sieve composed of a sieve frame and a filter screen is fixedly connected inside the first baffle. A vibration motor is fixedly connected to the other side of the first baffle. Positioning strips are fixedly connected to the front and rear sides of the second baffle, and a fixing rod is fixedly connected to the other side of the second baffle. A first groove in the shape of a cylinder and a second groove in the shape of a long strip are opened on one side of the feed port.

[0007] Preferably, a handle with a spherical upper end is fixedly connected to the top of the second baffle, and a wire mesh composed of multiple groups of iron wires is arranged inside the rubber ring.

[0008] Preferably, a reinforcing rod for increasing its hardness is arranged inside the fixing rod, and a rubber layer is fixedly connected to the outside of the fixing rod, and the rubber layer is closely attached to the first groove opened at the top of the feed port.

[0009] Preferably, the second groove opened at the inner wall edge of the feed inlet fits closely with the positioning strip, and the fixing rod is in the first groove which is cylindrically arranged at the top of the feed inlet.

[0010] Preferably, the number of the first grooves and the second grooves opened in the feed inlet is two each, and the vibration motor is arranged between the first baffle and the inner wall of the feed inlet.

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

[0012] In the present utility model, through the arranged stirring device, stirring motor, discharge port, feed inlet, rubber ring, first baffle, vibration motor and screen, the crushed coal gangue is poured into the stirring device from the feed inlet of the stirring device, and the coal gangue passes through the screen composed of a screen frame and a filter mesh. The vibration motor is started to drive the screen and the first baffle to vibrate simultaneously, and the coal gangue is vibrated and screened. The qualified coal gangue falls from the screen into the stirring device, and the coal gangue with larger particles remains on the surface of the screen. By arranging the wire mesh composed of multiple groups of iron wires in the rubber ring, the overall strength of the rubber ring is increased. At the same time, when the first baffle vibrates, since the first baffle and the second baffle are connected by the rubber ring, the vibration received at the second baffle is reduced. Through the arranged second baffle, positioning strip, fixing rod, first groove and second groove, after all the coal gangue is screened, the user can move the second baffle upward as a whole. It is convenient to move it through the handle arranged above the second baffle, driving the first baffle and the screen plate to move upward simultaneously until it is taken out. Then, the coal gangue with larger particles at the screen plate is subjected to secondary crushing treatment, increasing the utilization rate of the raw materials and preventing waste. By arranging the rubber layer on the outer side of the fixing rod, the friction between the fixing rod and the first groove is increased, making it not easy to move after insertion. By arranging the reinforcing rod in the fixing rod, the strength of the fixing rod is increased. By arranging the removable screening device at the feeding place, the coal gangue can be screened out of the coal gangue with larger particles before being stirred with other materials, so that the coal gangue-containing cement is not likely to have its quality reduced or not meet the standard due to the larger particles of the coal gangue.

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0024] A preparation device for coal gangue-doped cement, comprising a stirring device 1 for evenly mixing a variety of materials, a stirring motor 2 for driving the stirring blades to rotate, a discharge port 3 and a feed port 4. The stirring motor 2 is provided at the top of the stirring device 1. The discharge port 3 with a trapezoidal cross-section is provided at the bottom of the stirring device 1. The feed port 4 in the shape of a cylindrical pipe is fixedly connected to the top of the stirring device 1. A second baffle 10 with a T-shaped cross-section is closely attached to one side of the feed port 4. A rubber ring 5 is fixedly connected to the bottom of the second baffle 10. A first baffle 7 is fixedly connected to the other side of the rubber ring 5. A sieve 9 composed of a sieve frame and a filter screen is fixedly connected inside the first baffle 7. A vibration motor 8 is fixedly connected to the other side of the first baffle 7. Positioning bars 11 are fixedly connected to the front and rear sides of the second baffle 10. A fixing rod 13 is fixedly connected to the other side of the second baffle 10. A first groove 16 in the shape of a cylinder and a second groove 17 in the shape of a long strip are provided on one side of the feed port 4. By providing a removable screening device at the feed inlet, larger particles of coal gangue can be screened out before the coal gangue is stirred with other materials, so that the coal gangue-doped cement is not easily reduced in quality or fails to meet the standards due to the large size of the coal gangue particles.

[0025] A handle 12 with a spherical upper end is fixedly connected to the top of the second baffle 10. A wire mesh 6 composed of multiple groups of iron wires is provided inside the rubber ring 5, which facilitates the movement of the second baffle 10 and increases the strength of the rubber ring 5. A reinforcing rod 14 for increasing its hardness is provided inside the fixing rod 13. A rubber layer 15 is fixedly connected to the outside of the fixing rod 13. The rubber layer 15 is closely attached to the first groove 16 provided at the top of the feed port 4, which increases the strength of the reinforcing rod 14 and at the same time increases the friction between the fixing rod 13 and the first groove 16, making it not easy to move after being inserted. The second groove 17 provided at the inner wall edge of the feed port 4 is closely attached to the positioning bar 11. The fixing rod 13 is in the first groove 16 in the shape of a cylinder provided at the top of the feed port 4, so that the second baffle 10 has a positioning effect during installation. The number of the first grooves 16 and the second grooves 17 provided in the feed port 4 is two each. The vibration motor 8 is provided between the inner walls of the first baffle 7 and the feed port 4, which facilitates the vibration of the first baffle 7.

[0026] Workflow: When the device is in operation, it is powered by an external power supply. When the coal gangue-doped cement preparation device is in use, first place the stirring device 1 in a suitable position, and place the screening device composed of the first baffle 7, the second baffle 10, the screen 9 and the vibration motor 8 at the feed inlet 4, that is, the positioning strip 11 on one side of the second baffle 10 is aligned with the second groove 17 opened at the feed inlet 4, and the fixing rod 13 on the other side of the second baffle 10 is aligned with the first groove 16. Move the whole screening device downward until the surfaces of the second baffle 10 and the top of the feed inlet 4 are closely attached. By setting the rubber layer 15 on the outside of the fixing rod 13, the friction between the fixing rod 13 and the first groove 16 is increased, making it not easy to move after insertion. By setting the reinforcing rod 14 in the fixing rod 13, the strength of the fixing rod 13 is increased. Put the crushed coal gangue into the feed inlet 4 of the stirring device 1 in proportion. The coal gangue falls from the feed inlet 4 onto the surface of the screen 9 composed of the screen frame and the filter screen. At this time, start the vibration motor 8 to drive the first baffle 7 and the screen 9 to vibrate simultaneously. At this time, the qualified coal gangue falls from the screen 9 into the stirring device 1. Since the first baffle 7 and the second baffle 10 are connected by the rubber ring 5, when the first baffle 7 vibrates, the rubber ring 5 has a shock-absorbing effect on the second baffle 10. By setting the wire mesh 6 composed of iron wires in the rubber ring 5, the strength of the rubber ring 5 is increased. After all the coal gangue is put into the stirring device 1, the user holds the handle 12 and moves the whole screening device upward until it is taken out. The unqualified coal gangue remains in the space composed of the screen 9 and the first baffle 7. After the whole is taken out, the coal gangue with larger particles is subjected to secondary crushing treatment, increasing the utilization rate of raw materials so that it will not be wasted. Then, put the remaining materials into the stirring device 1 in proportion and stir evenly. By setting the removable screening device at the feeding place, the coal gangue can be screened out of the larger particle coal gangue before being stirred with other materials, so that the coal gangue-doped cement is not easy to have its quality reduced or not meet the standard due to the larger particle size of the coal gangue.
