Description

Technical Field

[0001] The utility model relates to the technical field of mine filling, in particular to a horizontal stirring barrel with a material discharge dredging structure. Background Art

[0002] In the mine filling industry, the mixing barrel plays an important role in the entire process as a mixing and stirring equipment for filling materials such as coagulants, ore tailings, and water. As a horizontal mixing barrel before the slurry pumping or slurry self-flowing process, the filling raw materials can be fully stirred to prepare a slurry that meets the filling concentration standard requirements.

[0003] For mines with relatively high strength requirements after filling, the concentration of the filling slurry is generally high. In order to prevent large particles of sand and gravel from clogging the pipe, a filter is generally installed at the discharge end of the horizontal mixing barrel. When the slurry flows out of the horizontal mixing barrel, the slurry flow rate is slow. The continuous input of raw materials from the previous process will cause the liquid level in the horizontal mixing barrel to gradually rise, and there may even be a risk of overflow, affecting filling safety and production progress.

[0004] At present, surveillance cameras are usually installed at this process, and special personnel need to be arranged for monitoring. When the filling concentration is high, material discharge is not smooth, and there is a risk of overflow, personnel need to be transferred in time to clear the problem, which is time-consuming and labor-intensive and affects production safety.

[0005] To this end, the present application designs a horizontal mixing barrel with a material discharge and dredging structure to solve the above-mentioned problems. Summary of the invention

[0007] A horizontal mixing barrel with a material discharge dredging structure comprises a horizontal mixing barrel, characterized in that:

[0008] The unloading end of the horizontal mixing barrel is equipped with a material level detection device and a water spray stirring device that can reciprocate and lift; the material level detection device is installed on a base frame, and a vertical guide rail is provided on the base frame, and the base frame is installed at the unloading end of the horizontal mixing barrel; the water spray stirring device is installed on a lifting frame, and a groove wheel is installed on the lifting frame, which can be lifted up and down along the guide rail on the base frame.

[0009] Furthermore, in order to better realize the utility model, a screw elevator is installed on the lifting frame, the screw flange end of the screw elevator is fixed on the horizontal mixing barrel, and the lifting of the lifting frame is controlled by the screw elevator.

[0010] Furthermore, in order to better realize the utility model, the water spray stirring device includes a mounting plate fixedly connected to the lifting frame, a motor is installed on one side of the mounting plate, the motor is connected to the reducer, the output shaft of the reducer is connected to the first connecting rod arranged on the other side of the mounting plate, the first connecting rod is connected to the second connecting rod, the second connecting rod is connected to the stirring rod, the stirring rod is inserted into a guide seat fixed on the mounting plate, and the stirring rod reciprocates up and down along the guide seat driven by the motor.

[0012] The beneficial effects of the utility model are:

[0013] The utility model uses a material level detection device to determine whether intervention is needed in the discharge of slurry in the horizontal mixing barrel. When the material level is too high, the material discharge and dredging operation is started in time to prevent the slurry from overflowing the barrel and causing production safety accidents. It can replace manual operation, improve the degree of automation, facilitate remote centralized control, improve production efficiency, and ensure production safety.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0022] Figure 1-Figure 4 This is a specific embodiment of the present invention, which is a horizontal mixing barrel with a material discharge dredging structure. The base frame 2 and the water spray stirring device 3 are located above the material discharge port 101 of the horizontal mixing barrel 1 and are fixedly installed on the mixing barrel. The water spray stirring device 3 is fixed on the lifting frame 7. The four corners of the lifting frame 7 are equipped with groove wheels 5. The inner side of the base frame 2 is equipped with a guide rail 8. The screw flange end of the screw elevator 4 is installed on the barrel body of the horizontal mixing barrel 1, and the body is installed on the lifting frame 7. When the screw elevator 4 is started, the lifting frame 7 and the water spray stirring device 3 can be lifted up and down along the guide rail 8 in the support of the groove wheel 5.

[0023] The stirring rod 305 of the water-spraying stirring device 3 can reciprocate up and down along the guide seat 306 under the drive of the motor 302 and the connecting rod 303 / 304, and is connected to the water pipe through the water inlet of the side branch 3051, and the water outlet 3052 injects water into the ore slurry to dilute the ore slurry.

[0024] Under normal conditions, the stirring rod 305 of the water-spraying stirring device 3 is parked above the slurry surface to prevent the slurry from hardening at the water outlet 3052 in the slurry and affecting normal use. The stirring impeller 102 of the horizontal stirring barrel 1 spirally transports the slurry to the discharge port 101 to enter the next process.

[0025] When the material level detection device 6 detects that the liquid level in the horizontal mixing barrel 1 exceeds the set height, it is judged that the slurry concentration is too high and the material discharge is not smooth. The screw elevator 4 is controlled to start, driving the lifting frame 7 and the water spray stirring device 3 to descend to the working height, and the side branch 3051 of the stirring rod 305 is filled with water. The motor 302 drives the stirring rod 305 to reciprocate up and down at the discharge port 101, and the slurry is diluted by water injection, so as to achieve the purpose of unblocking the discharge port and quickly discharge the material.

[0026] When the liquid level drops to the set safety height, the screw elevator 4 raises the water spray stirring device 3 and the lifting frame 7 along the guide rail 8 to the parking position, and the water inlet of the side branch 3051 of the stirring rod 305 is closed to complete the unloading and dredging work of the horizontal stirring barrel 1.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
