Description

Technical Field

[0001] The present application relates to the technical field of roasting furnaces, and in particular to a material distribution device for an overflow port of a roasting furnace. Background Art

[0002] Overflow ports are located at appropriate locations within the roaster (e.g., approximately 1 meter above the furnace floor) to control the flow of materials within the roaster. As materials are heated and undergo physical or chemical changes within the furnace, some may expand, soften, or liquefy, causing them to flow upward. The overflow ports ensure that this material escapes the furnace at a steady rate and flow rate, preventing excessive accumulation or blockage.

[0003] A dividing plate is usually set in the overflow port to form two discharge channels. By adjusting the angle of the dividing plate, the opening of the channel is changed, thereby ensuring uniform discharge of materials from the two channels.

[0004] However, the traditional dividing plate adjustment operation is completed manually, which relies on manual experience and results in poor adjustment accuracy. Utility Model Content

[0030] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.

[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0032] Example 1:

[0033] See also Figure 1 and Figure 2 , a roasting furnace overflow outlet material distribution device, the roasting furnace overflow outlet material distribution device comprising:

[0034] A first material distributor plate 1 and a second material distributor plate 2 are hingedly mounted in the overflow port 16. The first material distributor plate 1 and one side of the overflow port 16 form a first discharge channel 3. The second material distributor plate 2 and the other side of the overflow port 16 form a second discharge channel 4.

[0035] Among them, the first distribution plate 1 and the second distribution plate 2 are driven by the first cylinder 5 and the second cylinder 6 respectively, the outside of the first discharge channel 3 is provided with a first microwave solid flowmeter 7, and the outside of the second discharge channel 4 is provided with a second microwave solid flowmeter 8.

[0036] Specifically, the first and second distributor plates 1 and 2 are coaxially hingedly mounted, similar to door hinges. When the first distributor plate 1 rotates upward, its lower end gradually approaches the inner wall of the overflow port 16, reducing the opening of the first discharge channel 3 and thereby reducing the discharge volume. When the first distributor plate 1 rotates downward, its lower end gradually moves away from the inner wall of the overflow port 16, widening the opening of the first discharge channel 3 and thereby increasing the discharge volume. The opening of the second discharge channel 4 can be adjusted similarly.

[0037] In this embodiment, the mineral material flow in the first discharge channel 3 is measured in real time by the first microwave solid flowmeter 7, and the mineral material flow in the second discharge channel 4 is measured in real time by the second microwave solid flowmeter 8. When it is detected that the flow rates of the two are inconsistent, the first cylinder 5 or the second cylinder 6 is controlled to operate to change the rotation angle of the first dividing plate 1 or the second dividing plate 2, so as to adjust the opening of the first discharge channel 3 or the first discharge channel 3. During the adjustment process, the first cylinder 5 and the second cylinder 6 continuously receive signal feedback from the first microwave solid flowmeter 7 and the second microwave solid flowmeter 8, and continue to operate according to the feedback until the flow rates in the first discharge channel 3 and the second discharge channel 4 are consistent.

[0038] In addition, when blockage occurs, the first cylinder 5 or the second cylinder 6 can adjust the opening of the discharge channel in time through the signal feedback of the first microwave solid flowmeter 7 or the second microwave solid flowmeter 8 to avoid prolonged blockage.

[0039] In this embodiment, the detection feedback of two microwave solid flow meters is used to control the movement of two cylinders, and the angle adjustment of the two material distribution plates is achieved through the two cylinders, thereby avoiding the problem of poor adjustment accuracy caused by manual adjustment.

[0040] It should be noted that the first microwave solid flowmeter 7 and the second microwave solid flowmeter 8 are both connected to the controller. The controller receives detection signals from the two to control the first cylinder 5 and the second cylinder 6 to perform corresponding actions, thereby achieving automatic and precise adjustment through the controller.

[0041] It should be noted that the working principle of the microwave solid flow meter is based on the microwave Doppler effect and the reflection characteristics of solid particles to microwaves. By measuring the frequency change of the reflected wave, the amount and flow rate of solid materials in the pipeline are calculated. It can promptly detect and deal with problems such as blockage and bridging.

[0042] Example 2:

[0043] See also Figure 1 and Figure 2Based on Example 1, optionally, a pin 9 is provided in the overflow port 16 , the upper end of the first dividing plate 1 is hinged to the pin 9 through a first sleeve 10 , and the upper end of the second dividing plate 2 is hinged to the pin 9 through a second sleeve 11 .

[0044] Specifically, the two ends of the pin 9 are respectively fixed to the two side walls of the overflow port 16, and a through hole matching the pin 9 is opened in the middle of the first sleeve 10. The first sleeve 10 is rotatably connected to the pin 9 through the through hole. The outer surface of the first sleeve 10 is fixedly connected to the upper end of the first dividing plate 1. In this way, the hinged connection between the first dividing plate 1 and the pin 9 is realized;

[0045] There are two second sleeves 11, which are located on both sides of the first sleeve 10 respectively. A through hole matching the pin 9 is opened in the middle of the second sleeve 11. The second sleeve 11 is rotatably connected to the pin 9 through the through hole. The outer surface of the second sleeve 11 is fixedly connected to the upper end of the second dividing plate 2. In this way, the second dividing plate 2 and the pin 9 are hinged.

[0046] Optionally, the first dividing plate 1 includes a first inclined plate 12 and a first baffle 13;

[0047] The lower end surface of the first inclined plate 12 is connected to the movable end of the first cylinder 5 , and the first microwave solid flowmeter 7 is installed on the outer wall of the overflow port 16 opposite to the first baffle 13 .

[0048] Specifically, the first inclined plate 12 is used to guide the mineral materials into the first discharge channel 3, and the first baffle 13 restricts the falling mineral materials to prevent them from being excessively dispersed.

[0049] In the area of ​​first discharge channel 3 corresponding to first baffle 13, the flow of mineral material is relatively stable and continuous, making it suitable for the installation of first microwave solids flowmeter 7. First baffle 13 has an upper limit and a lower limit. The upper and lower limit positions are pre-set to ensure that the opening of first discharge channel 3 can be adjusted within a certain range. To ensure that first microwave solids flowmeter 7 is always effective, first microwave solids flowmeter 7 should be located between the upper and lower limit positions.

[0050] Optionally, the second distributor plate 2 includes a second inclined plate 14 and a second baffle 15;

[0051] The lower end surface of the second inclined plate 14 is connected to the movable end of the second cylinder 6 , and the second microwave solid flowmeter 8 is installed on the outer wall of the overflow port 16 opposite to the second baffle 15 .

[0052] Specifically, the second inclined plate 14 is used to guide the mineral materials into the second discharge channel 4, and the second baffle 15 restricts the falling mineral materials to prevent them from being excessively dispersed.

[0053] In the area of ​​second discharge channel 4 corresponding to second baffle 15, the flow of mineral material is relatively stable and continuous, making it suitable for the installation of second microwave solids flowmeter 8. Second baffle 15 has an upper limit and a lower limit. The upper and lower limit positions are pre-set to ensure that the opening of second discharge channel 4 can be adjusted within a certain range. To ensure that second microwave solids flowmeter 8 is always effective, it should be located between the upper and lower limit positions.

[0054] Optionally, the first cylinder 5 and the second cylinder 6 are symmetrical about a vertical line of the pin 9 .

[0055] Specifically, this embodiment provides an arrangement of the first cylinder 5 and the second cylinder 6, such as Figure 1 As shown, the first cylinder 5 and the second cylinder 6 are symmetrical about the vertical line of the pin 9 .

[0056] Optionally, the first cylinder 5 and the second cylinder 6 are arranged along the length of the pin shaft 9 .

[0057] Specifically, this embodiment provides another arrangement of the first cylinder 5 and the second cylinder 6 , that is, the first cylinder 5 and the second cylinder 6 are arranged along the length of the pin 9 .

[0058] Optionally, both the first cylinder 5 and the second cylinder 6 are high-temperature resistant cylinders.

[0059] Specifically, considering that the temperature of the ore is relatively high during the roasting operation, in order to ensure the performance and service life of the cylinders, the first cylinder 5 and the second cylinder 6 are high-temperature resistant cylinders.
