Description

Technical Field

[0001] This utility model relates to the field of titanium-iron powder raw material conveying and feeding technology, and more specifically, to a metering device for titanium-iron powder raw material conveying and feeding. Background Technology

[0002] The ferrotitanium powder raw material conveying and feeding device is a complete set of equipment used to transport ferrotitanium powder from the raw material silo to the subsequent stages. The material in the raw material silo is connected to the top of the hopper through the conveying pipe. A conveyor belt is set at the bottom opening of the hopper. In order to adapt to the continuous feeding of the conveyor belt, a box-shaped hopper is generally used as the feeding hopper. In order to ensure that a certain amount of raw material is fed each time, the material is usually weighed quantitatively in the feeding hopper by a level gauge. The level gauge cannot be installed vertically below the outlet of the conveying pipe, and the material needs to be weighed quantitatively before the weighed hopper is discharged. Finally, the material is transported to the subsequent stages by the bottom conveyor belt.

[0003] Existing metering devices for conveying and feeding titanium iron powder raw materials cannot perform metering and weighing and material transfer simultaneously. They require metering and weighing first and then transferring the material. Furthermore, when the titanium iron powder raw materials are put into the hopper through the conveying pipeline, the material is prone to accumulation vertically below the outlet of the conveying pipeline, causing errors in the quantitative weighing of the material level gauge at the edge. The feeding speed is slow and the metering is inaccurate, which can easily lead to large errors. In view of this, we propose a metering device for conveying and feeding titanium iron powder raw materials. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a metering device for conveying and feeding titanium iron powder raw materials, so as to solve the technical problem of poor functionality of the existing metering devices for conveying and feeding titanium iron powder raw materials.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metering device for conveying and feeding titanium iron powder raw materials, including a hopper, a weight-detecting level gauge is installed at the top of the hopper, an electromagnetic valve and a raw material silo discharge pipe are installed at the top feeding port of the hopper, a conveyor belt is provided below the discharge port of the hopper, a material distributor is slidably installed in the upper part of the hopper, a metering device is rotatably connected in the lower part of the hopper, the power input end of the metering device is connected to a Geneva wheel drive mechanism, and the power output end of the Geneva wheel drive mechanism is also connected to the material distributor through a cam transmission mechanism;

[0006] The metering device includes a metering housing, a rotating rod is fixedly connected to the axis of the metering housing and is rotatably connected to the lower part of the hopper through the rotating rod, and two metering slots are opened opposite each other on the outside of the metering housing;

[0007] The feeder includes an arched distribution filter plate located below the top feed port of the hopper. The top two arc edges of the arched distribution filter plate are fixedly equipped with side arc plates, and the arched distribution filter plate is arranged parallel above the metering trough.

[0008] Preferably, the hopper includes a box-shaped hopper, and the upper part of the box-shaped hopper is provided with a sliding groove.

[0009] Preferably, slide rods are fixedly installed on both sides of the bottom of the arched distribution filter, the slide rods are slidably connected in the slide groove, and end plates are fixedly installed at the ends of the slide rods.

[0010] Preferably, the Geneva drive mechanism includes a driven Geneva wheel fixedly mounted on the end of the rotating rod, and an active dial with a cylindrical pin is adapted to be connected to the driven Geneva wheel. The power input end of the active dial with the cylindrical pin is connected to a servo motor.

[0011] Preferably, the cam transmission mechanism includes a cam disk, which is fixedly mounted outside the drive dial equipped with a cylindrical pin. A driven wheel is adapted to be connected to the top of the cam disk, and the driven wheel is rotatably mounted on the end plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a grooved wheel drive mechanism to drive the metering device to rotate intermittently. Combined with a weighted level gauge and a solenoid valve at the feeding port, it enables continuous quantitative feeding. Metering, weighing, and material transfer are carried out simultaneously, improving production efficiency. At the same time, the grooved wheel drive mechanism continuously drives the distributor to move up and down repeatedly, continuously distributing the material added at the feeding port into the metering tank. This allows the weighted level gauge to measure and weigh more accurately, solving the problem of poor functionality in existing metering devices for conveying and feeding titanium iron powder raw materials.

[0014] 2. This utility model also designs an arched distribution filter structure, with the upper arc end of the arched distribution filter structure facing the feed inlet of the hopper. When the titanium iron powder raw material is added from the feed inlet and falls from a height, the titanium iron powder raw material falls to different positions on the top of the arched distribution filter. Part of it leaks through the filter holes of the arched distribution filter into the middle of the metering tank, while the gravitational potential energy of the other part is converted into kinetic energy, causing the titanium iron powder raw material at different positions to fall at different speeds and slide through the arc surface of the arched distribution filter to different positions on both sides of the metering tank. This prevents the titanium iron powder raw material from accumulating in the middle of the metering tank and further solves the problem of poor functionality of the existing titanium iron powder raw material conveying and feeding metering devices.

[0026] like Figures 1 to 5 As shown, this utility model relates to a metering device for conveying and feeding titanium iron powder raw materials, including a hopper 1, a weighted detection type level gauge 2 is installed at the top of the hopper 1, an electromagnetic valve 9 and a raw material silo discharge pipe 3 are installed at the top feeding port of the hopper 1, a conveyor belt 4 is installed below the discharge port of the hopper 1, a material distributor 8 is slidably installed in the upper part of the hopper 1, a metering device 7 is rotatably connected in the lower part of the hopper 1, the power input end of the metering device 7 is connected to a Geneva wheel drive mechanism 5, and the power output end of the Geneva wheel drive mechanism 5 is also connected to the material distributor 8 through a cam transmission mechanism 6;

[0027] Meter 7 includes a metering housing 702. A rotating rod 701 is fixedly connected to the axis of the metering housing 702 and is rotatably connected to the lower part of the hopper 1 through the rotating rod 701. Two metering slots 703 are opened opposite each other on the outside of the metering housing 702.

[0028] The material distributor 8 includes an arched distribution filter 801, which is located below the top feeding port of the hopper 1. Two arc-shaped edge plates 802 are fixedly installed on the top two arc edges of the arched distribution filter 801. The arched distribution filter 801 is arranged parallel above the metering trough 703. This invention uses a grooved wheel drive mechanism 5 to drive the metering device 7 to rotate intermittently. Combined with a weighted level gauge 2 and a solenoid valve 9 at the feeding port, continuous quantitative feeding is possible. Metering, weighing, and material transfer are performed simultaneously, improving production efficiency. Simultaneously, the grooved wheel drive mechanism 5 continuously drives the material distributor 8 to move up and down reciprocally, continuously distributing the material added at the feeding port into the metering trough 703. This design enables the weighted level gauge 2 to measure and weigh more accurately. Furthermore, by designing an arched distribution filter 801 structure, with the arc end of the arched distribution filter 801 facing the feed inlet of the hopper 1, when the ferrotitanium powder is added from the feed inlet and falls from a height, the ferrotitanium powder falls to different positions on the top of the arched distribution filter 801. Part of it leaks through the filter holes of the arched distribution filter 801 into the middle of the metering tank 703, while the gravitational potential energy of the other part is converted into kinetic energy, causing the ferrotitanium powder at different positions to fall at different speeds and slide through the arc surface of the arched distribution filter 801 to different positions on both sides of the metering tank 703, preventing the ferrotitanium powder from accumulating in the middle of the metering tank 703.

[0029] Furthermore, the hopper 1 includes a box-shaped hopper 101, and a groove 102 is provided on the upper part of the box-shaped hopper 101 to facilitate the sliding rod 803 to slide up and down in the groove 102.

[0030] Furthermore, slide rods 803 are fixedly installed on both sides of the bottom of the arched distribution filter 801. The slide rods 803 are slidably connected in the slide groove 102. End plates 804 are fixedly installed at the ends of the slide rods 803, which allows the arched distribution filter 801 to move up and down together with the slide rods 803.

[0031] Furthermore, the Geneva drive mechanism 5 includes a driven Geneva 503 fixedly mounted on the end of the rotating rod 701. An active dial 502 with a cylindrical pin is externally adapted to the driven Geneva 503. The power input end of the active dial 502 with the cylindrical pin is connected to a servo motor 501 for easy driving.

[0032] Furthermore, the cam transmission mechanism 6 includes a cam disk 601, which is fixedly mounted on the outside of the drive dial 502 equipped with a cylindrical pin. A driven wheel 602 is adapted to be connected to the top of the cam disk 601. The driven wheel 602 is rotatably mounted on the end piece 804 for convenient transmission.

[0033] Working Principle: This embodiment provides a metering device for conveying and feeding ferrotitanium powder raw materials. In use, the device drives the metering device 7 to rotate intermittently via a grooved wheel drive mechanism 5. Combined with a weighted level gauge 2 and a solenoid valve 9 at the feeding port, continuous quantitative feeding is possible. Metering, weighing, and material transfer are performed simultaneously, improving production efficiency. Simultaneously, the grooved wheel drive mechanism 5 continuously drives the distributor 8 to move up and down reciprocally, continuously distributing the material added at the feeding port into the metering trough 703, allowing the weighted level gauge 2 to measure more accurately. Powered by an external power supply, the servo motor 501 is turned on via an external switch. The servo motor 501 drives the active dial 50 equipped with a cylindrical pin. 2. Continuous rotation drives the externally adapted driven grooved wheel 503 to rotate intermittently, and the metering device 7 rotates intermittently in sync. When the metering groove 703 rotates to the top, the metering device 7 stops rotating due to the intermittent rotation driven by the grooved wheel drive mechanism 5. External power supply is used to open the solenoid valve 9 through an external switch, and the raw material hopper discharge pipe 3 connected to the raw material hopper continuously feeds material into the hopper 1. The titanium iron powder raw material continuously pours onto the arched distribution filter plate 801. The upper arc end of the arched distribution filter plate 801 faces the feed inlet of the hopper 1. When the titanium iron powder raw material is added from the feed inlet and falls from a height, the titanium iron powder raw material falls to different positions on the top of the arched distribution filter plate 801, part of which falls from the arched distribution filter plate 801. The ferrite powder leaks through the filter holes into the middle of the metering tank 703. The gravitational potential energy of the remaining portion is converted into kinetic energy, causing the ferrite powder at different locations to fall at different speeds. It slides along the arc surface of the arched distribution filter 801 to different positions on both sides of the metering tank 703, preventing the ferrite powder from accumulating in the middle of the metering tank 703. Simultaneously, the active dial 502, equipped with cylindrical pins, rotates continuously, driving the cam disk 601 to rotate continuously. Because the cam disk 601 has several sets of intermittently arranged protrusions and concave parts, it can drive the driven wheel 602 to reciprocate up and down. The slide rod 803 slides up and down within the slide groove 102, and the arched distribution filter 801 moves up and down along with the slide rod 803. When the arched distribution filter... When 801 moves up and down, the titanium iron powder raw material sliding down along the arched distribution filter 801 can slide to different positions at both ends of the metering tank 703, distributing the material more evenly. The weighted level gauge 2 continuously measures and weighs the material in the upper metering tank 703 until the material quantity reaches the standard and closes the solenoid valve 9. After the groove wheel drive mechanism 5 drives the metering device 7 to rotate intermittently until the empty metering tank 703 rotates to the top, the solenoid valve 9 is opened again, and the metering tank 703 containing titanium iron powder raw material rotates to the bottom and starts unloading simultaneously. This process is repeated (the weighted level gauge 2, conveyor belt 4, groove wheel drive mechanism 5 and solenoid valve 9 are all existing products on the market and are connected to external control switches and power supplies).
