Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical charge cooling, and particularly relates to a cooling device for metallurgical charge production. Background Art

[0002] After the metallurgical charge is calcined, it needs to be cooled. In the existing cooling methods, the charge is put into water for cooling. For example, the patent application number 202322610541.3 discloses a rapid cooling device for metallurgical charge production, including a cooling tank, a circulation pipe, a cooling structure, etc. Through the setting of the partition net, it can prevent the cooled materials from sinking to the bottom, resulting in inconvenient fishing. Through the setting of the filter screen, it can prevent debris from entering the cooling structure along the circulation pipe, thus affecting the use of the cooling structure. Through the setting of the material frame, after the material is put into the cooling tank, it will fall on the partition net and then roll down along the inclination of the partition net until it falls into the material frame. After waiting for the charge to cool down, the charge can be collected by taking the material frame, which is more convenient for taking out the charge.

[0003] The above-mentioned disclosed solution for charge cooling has the following defects in use: First, after the raw materials slide from the inclined partition net to the material frame, they will pile up together, resulting in the raw materials being in contact with each other. The contact surface is not easy to contact water for cooling, thus causing the phenomenon that the raw materials still cool slowly. Second, the method of manually taking the material frame by hand will result in a large amount of manual work and is inconvenient to save the physical strength of the staff, thus causing the phenomenon that it is still inconvenient to take out the raw materials. Summary of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a cooling device for metallurgical charge production. The raw materials can move back and forth on the pallet, and cooperate with the arc plate to easily generate gaps during the movement, so that the originally contacting surfaces can contact the water flow for cooling, improving the cooling speed of the raw materials. Through the conveyor belt and the magnet block, the raw materials are adsorbed and carried out of the box body, avoiding the phenomenon of manual taking, reducing the manual workload, and being convenient to save the physical strength of the staff.

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

[0006] A cooling device for metallurgical charge production, comprising a box body. An opening is provided at the top of the box body. A drain pipe is communicated with the bottom of the right side of the box body. A tray is arranged in the box body. The left end of the tray is rotatably connected with the front and rear inner walls of the box body. A plurality of arc-shaped plates are fixedly connected to the upper surface of the tray at equal intervals. A plurality of through holes are formed in the tray. A filter screen is fixedly connected in the through holes. A cylinder located below the tray is fixedly connected to the bottom of the inner cavity of the box body. An installation plate is fixedly connected to the top of the box body. A driving shaft is rotatably connected to one side of the installation plate. A motor is fixedly connected to the other side of the installation plate. The output shaft of the motor is fixedly connected to the driving shaft. A driven shaft is rotatably connected between the front and rear inner walls of the box body. The driven shaft is located directly below the driving shaft. The driving shaft and the driven shaft are connected by a conveyor belt. The front and rear sides of the conveyor belt and the tray are all in contact with the inner part of the box body. The outer side of the right part of the conveyor belt is in contact with the left end of the tray. A plurality of magnet blocks are fixedly connected to the inner side of the left part of the conveyor belt at equal intervals. A scraper is fixedly connected to the left side of the top of the box body. The scraper is inclined upward from left to right. The top of the scraper is in contact with the left part of the conveyor belt.

[0007] Further, the right end of the tray is in contact with the right side of the inner cavity of the box body. The right end of the tray and the right side of the inner cavity of the box body are both arc surfaces with adapted radian.

[0008] Further, a roller is rotatably connected to the top of the telescopic end of the cylinder.

[0009] Further, a limiting plate is fixedly connected to the inner wall of the box body. The left side of the limiting plate is in contact with the inner side of the left part of the conveyor belt. The right side of the limiting plate is in contact with the inner side of the right part of the conveyor belt.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. By the way of driving the tray to move by the cylinder, the originally static raw materials can move back and forth on the tray. Cooperating with the arc-shaped plates, gaps are easily generated in the movement of the raw materials, so that the originally adhered surfaces can contact the water flow and be cooled, improving the cooling speed of the raw materials. Secondly, by driving the conveyor belt to work by the motor, the raw materials are adsorbed by the magnet blocks and carried out of the box body, and the raw materials on the conveyor belt are scraped off by the scraper, thus avoiding the phenomenon of manual taking and reducing the manual workload, which is convenient for saving the physical strength of the staff. The filter screen prevents the smaller raw materials from passing through the through holes.

[0012] 2. Through the arc surface design of the pallet and the box body, when the right end of the pallet moves, it can keep in contact with the inner wall of the box body, avoiding the generation of gaps between the two, which may cause the raw materials to slide off the pallet. The rotating roller reduces the friction between the telescopic end of the cylinder and the bottom of the pallet during operation. The limiting plate prevents the conveyor belt from sagging inward. That is, when the scraper scrapes off the raw materials, it avoids the left part of the conveyor belt from sagging, resulting in uncleaned raw materials. Also, when the raw materials slide to the left end of the pallet, it avoids the right part of the conveyor belt from sagging and generating gaps with the pallet, which may cause the raw materials to slide off the pallet through the gaps.

Embodiment

[0020] See attached Figures 1-4As shown in the figure, a cooling device for metallurgical furnace charge production includes a box body 1. There is an opening at the top of the box body 1. A drain pipe is connected to the bottom on the right side of the box body 1. A support plate 2 is arranged inside the box body 1. The left end of the support plate 2 is rotatably connected to the front and rear inner walls of the box body 1. A plurality of arc-shaped plates 3 are fixedly connected to the upper surface of the support plate 2 at equal intervals. A plurality of through holes are formed in the support plate 2, and a filter screen 4 is fixedly connected inside the through holes. The bottom of the inner cavity of the box body 1 is fixedly connected with a cylinder 5 located below the support plate 2. The top of the box body 1 is fixedly connected with a mounting plate 6. A driving shaft 7 is rotatably connected to one side of the mounting plate 6. A motor 8 is fixedly connected to the other side of the mounting plate 6. The output shaft of the motor 8 is fixedly connected to the driving shaft 7. A driven shaft 9 is rotatably connected between the front and rear inner walls of the box body 1. The driven shaft 9 is located directly below the driving shaft 7. The driving shaft 7 and the driven shaft 9 are connected by a conveyor belt 10 in transmission. The front and rear sides of the conveyor belt 10 and the support plate 2 are all in contact with the inside of the box body 1. The outer side of the right part of the conveyor belt 10 is in contact with the left end of the support plate 2. A plurality of magnet blocks 11 are fixedly connected to the inner side of the left part of the conveyor belt 10 at equal intervals. A scraper 12 is fixedly connected to the left side of the top of the box body 1. The scraper 12 is inclined upward from left to right, and the top of the scraper 12 is in contact with the left part of the conveyor belt 10.

[0021] The right end of the support plate 2 is in contact with the right side of the inner cavity of the box body 1. The right end of the support plate 2 and the right side of the inner cavity of the box body 1 are both arc surfaces with adapted radian. The right end of the support plate 2 will move upward or downward along an arc-shaped trajectory with the axis at the connection point of the left end, so the radian of the arc surface should be suitable for the movement trajectory.

[0022] The top of the telescopic end of the cylinder 5 is rotatably connected with a roller 13. When the telescopic end of the cylinder 5 moves, the right end of the support plate 2 will move along an arc-shaped trajectory, so the contact area between the roller 13 and the support plate 2 will change, causing the roller 13 to rotate by friction with the bottom of the support plate 2.

[0023] The inner wall of the box body 1 is fixedly connected with a limiting plate 14. The left side of the limiting plate 14 is in contact with the inner side of the left part of the conveyor belt 10, and the right side of the limiting plate 14 is in contact with the inner side of the right part of the conveyor belt 10. When the scraper 12 scrapes off the raw materials, the limiting plate 14 limits the position of the left part of the conveyor belt 10, so that the scraper 12 can keep in contact with the conveyor belt 10. When the raw materials slide to the left end of the support plate 2, the limiting plate 14 limits the position of the right part of the conveyor belt 10, so that the left end of the support plate 2 can keep in contact with the conveyor belt 10.

[0024] Working principle: In this utility model, water flow is continuously conveyed into the box body 1 from the top opening of the box body 1. After a certain amount of water is stored in the box body 1, the valve of the drain pipe is opened to keep the water flow for cooling continuously flowing in the box body 1, and the water inflow and outflow reach a dynamic balance. The calcined raw materials are placed on the pallet 2. It should be noted that at this time, the raw materials are overheated, and contacting the conveyor belt 10 will cause damage. The air cylinder 5 should be started, and the telescopic end of the air cylinder 5 descends, so that the right end of the pallet 2 tilts downward. In this way, after the raw materials are placed, they will be entirely in the right part area of the pallet 2 and first cool down in a static state. After the raw materials are initially cooled, at this time, in the area where the raw materials are in contact with each other, it is not easy to contact the water flow, so the cooling effect is poor. Then, the telescopic end of the air cylinder 5 reciprocates up and down, and the right end of the pallet 2 tilts up or down along with the air cylinder 5. When the right end of the pallet 2 is higher than the left end, the raw materials slide from the right to the left. Similarly, when the right end of the pallet 2 is lower than the left end, the raw materials slide from the left to the right. The raw materials are likely to separate and generate gaps during movement. Moreover, when the raw materials pass through the arc-shaped plate 3, the raw materials that pass through the arc-shaped plate 3 first will separate from the raw materials that have not passed through the arc-shaped plate, making it more difficult for the raw materials to fit together. Continuing like this, during the back-and-forth movement of the pallet 2, the original contact area of the raw materials is cooled. The filter screen 4 blocks the raw materials and prevents the raw material debris from passing through the through holes. After the raw materials are cooled, the motor 8 is started to drive the main shaft 7 to rotate, and the conveyor belt 10 is driven in cooperation with the driven shaft 9. When the conveyor belt 10 is moving, the part with the magnet block 11 on the left moves to the right, and the air cylinder 5 drives the right end of the pallet 2 to tilt upward, keeping the raw materials on the left part of the pallet 2 and able to contact the conveyor belt 10. When the magnet block 11 passes by the pallet 2, it adsorbs the raw materials. Then, the conveyor belt 10 carries the raw materials upward out of the box body 1, and when passing by the scraper 12, the raw materials are scraped off by the scraper 12. A material box for storing raw materials is pre-placed on the left part of the box body 1. Then, the scraped-off raw materials fall into the material box, completing the work of taking out the raw materials.
