Description

Technical Field

[0001] The utility model relates to the technical field of rotary unloading valves, in particular to a novel rotary unloading device. Background Art

[0002] The rotary valve unloading device is a device used to control the flow and unloading of materials. It is usually used in material conveying systems or containers in industrial production processes. It is usually composed of rotary valves, rotating parts, seals, etc. Its main function is to achieve the flow and unloading of materials by controlling the opening and closing of the valve, or by the rotation of the rotating parts. The design and operation of the rotary valve unloading device can be adjusted according to the specific application scenario and material characteristics to ensure that the material can be unloaded or flowed smoothly and efficiently. This device is widely used in chemical, grain processing, building materials and other fields, and is one of the important material handling equipment in the industrial production process.

[0003] At present, the existing rotary valve unloading device (such as patent announcement number: CN215827903U) discloses a rotary unloading valve with a leakage and wear-proof structure, including: a rotary unloading valve body, a feed port is fixedly connected to the upper part of the rotary unloading valve body, a connecting plate is fixedly provided above the feed port, and a sealing gasket is fixedly pasted on the upper surface of the connecting plate; a rotating column, which is movably installed on the outer side of the connecting plate, and a leak-proof plate is movably provided on the outer side of the rotating column; a sealing protective pad, which is fixedly pasted on the inner wall of the leak-proof plate. The utility model can make the leak-proof plate rotate upward through the rotating column, so that the leak-proof plate can be used to clamp and fix the connecting plate and other discharge devices, thereby preventing leakage through the sealing protective pad; the wear-resistant paint can reduce the wear of the material on the inner wall of the rotary unloading valve body when it is lowered, thereby increasing the service life of the device, thereby reducing wear, and the manual connecting shaft can be stirred through the card slot and the matching crank.

[0004] However, in the process of implementing the above technical scheme, it was found that there were at least the following technical problems: the rotary valve of the discharge bin is located below the discharge bin of the dryer, and transports the copper concentrate after being processed by the dryer. It is the throat equipment connecting the drying of the concentrate and the transportation of the concentrate. Since the new drying system was connected and put into use in 2013, there are many equipment failures such as the stuck rotor of the rotary valve due to the presence of foreign matter inside the copper concentrate that cannot be completely cleaned. The failure is unpredictable and there is no pattern to be found. It takes a long time to handle the failure and is very dangerous. Therefore, after the failure occurs, it has a great impact on the continuous production of the flash furnace at full load. Utility Model Content

The two motors are both located at the front end of the device main body, and the two motors correspond to the positions of the two rotating devices. A baffle is provided between the two rotating devices, and the baffle is fixedly connected to the inner wall of the device main body. Two holes are penetrated through the rear surface of the device main body, and the front surfaces of the two fixed frames are fixedly connected to the rear surface of the device main body.

[0010] Preferably, threaded rods are provided at both left and right ends inside the device body, and both front and rear ends of the two threaded rods are rotatably connected to the inner wall of the device body.

[0011] Preferably: long rods are provided at the upper and lower ends of the two threaded rods, and the front and rear ends of each long rod are fixedly connected to the inner wall of the device body, two movable columns are provided inside the device body, and each movable column is fixedly connected to a rubber eraser at one end away from the rotating device.

[0012] Preferably: the front surfaces of the two movable columns are penetrated with two holes corresponding to the position of the long rod, and each long rod is movably connected to the movable column through the second hole, and the front surfaces of the two movable columns are penetrated with a threaded groove, and each threaded rod is threadedly connected to the movable column through the threaded groove.

[0015] (III) Beneficial effects

[0016] 1. The assembly form of a single rotary valve body and a single rotating device is changed to a single body and two rotating devices. The two rotating devices rotate in different directions in an independent body through a baffle to transport materials. The principle is to reduce the space for copper concentrate to enter the rotor while ensuring the unchanged transport capacity.

[0017] 2. Rotate the rocker, which drives the driving sprocket and the short rod to rotate. Since the driving sprocket and the driven sprocket are engaged with the synchronous chain, the two short rods drive the threaded rod to rotate synchronously. Since the moving column does not rotate, the two moving columns will drive the rubber wiper to move along the direction of the long rod. The rubber wiper will clean the material attached to the inner wall of the device body when moving, avoiding the rotating device from re-conveyance of the material, thereby improving the conveying efficiency.

[0024] The embodiment of the present application provides a new type of rotary unloading device, which effectively solves the problem that the rotary valve of the discharge bin is located below the discharge bin of the dryer, and transports the copper concentrate processed by the dryer. It is the throat equipment connecting the concentrate drying and the concentrate transportation. Since the new drying system was docked and put into use in 2013, there are many equipment failures caused by the stuck rotor of the rotary valve due to the presence of foreign matter that cannot be completely cleaned inside the copper concentrate. The failure cannot be predicted, there is no pattern to be found, the fault handling time is long, and the risk is relatively high. Therefore, after the failure occurs, it has a great impact on the full-load continuous production of the flash furnace. The technical problem is that the assembly form of a single device body and a single rotating device of the rotary valve is changed to an equipment form of a single device body and two rotating devices. The two rotating devices rotate in different directions in an independent device body through a baffle to transport materials. The principle is to ensure that the conveying capacity remains unchanged while reducing the space for the copper concentrate to enter the rotor. Some large-sized debris in the material is not conducive to forming an unfavorable position for the rotary valve rotor to be stuck due to the squeezing effect of the material, thereby reducing the failure rate of the rotary valve getting stuck.
