Description

Technical Field

[0001] This utility model relates to the field of forced mixer technology, specifically to a device for preventing material blockage at the feed inlet of a forced mixer used in the preparation of refractory materials in tundishes. Background Technology

[0002] In the preparation of refractory materials for tundishes, the forced mixer is one of the core pieces of equipment. It is mainly used to thoroughly mix various refractory raw materials (such as magnesia, bauxite, graphite, etc.) with binders to form a homogeneous mixture. The feed inlet of the forced mixer is usually connected to a feed hopper, through which the material enters the mixer for mixing.

[0003] However, since the raw materials for refractory materials in tundishes are mostly granular or powdery, and some of them are hygroscopic, they are prone to clumping during storage and transportation. Simultaneously, during feeding, the material in the feed hopper can easily form bridging due to friction and adhesion between particles, leading to blockage at the feed inlet. Once blockage occurs, it not only interrupts feeding, affecting the normal operation of the mixer and reducing production efficiency, but also requires manual cleaning, increasing the labor intensity of operators and posing safety hazards during the cleaning process.

[0004] Therefore, we urgently need to provide a device to prevent material blockage at the feed inlet of a forced mixer for the preparation of refractory materials in intermediate ladles. Utility Model Content

[0005] The purpose of this invention is to provide a device to prevent material blockage at the feed inlet of a forced mixer for preparing refractory materials in tundishes, in order to solve the problem mentioned in the background art that the feed inlet is prone to blockage, affecting the normal operation of the mixer and reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing material blockage at the feed inlet of a forced mixer for preparing refractory materials in tundishes, comprising a forced mixer body and a feed inlet, wherein the feed inlet is installed on the top of the forced mixer body, and anti-blocking devices are provided inside and outside the feed inlet, the anti-blocking devices comprising a pushing mechanism and a knocking mechanism.

[0007] The pushing mechanism is located inside the feed inlet, and the striking mechanism is located outside the feed inlet.

[0008] The feeding mechanism includes a fixed rod, a housing, a connecting rod, a support platform, a motor, a rotating shaft, a gear, a cam, a push rod, a disc, and a spring. The fixed rod is fixedly installed on the left and right sides of the inner wall of the feed inlet. The housing is fixedly installed between the two fixed rods. The connecting rod is rotatably connected inside the housing and extends through the housing to the outside of the feed inlet. The support platform is fixedly installed on the top of the forced mixer body, located in front of the feed inlet. The motor is fixedly installed on the top of the support platform. The rotating shaft is fixedly installed at the output end of the motor. The gear is fixedly installed on the outside of the rotating shaft and the connecting rod. The cam is fixedly installed on the outside of the connecting rod and located inside the housing. The push rod is slidably installed inside the housing. The disc is fixedly installed on the top of the push rod. The spring is installed inside the housing and located on the outside of the push rod.

[0009] Preferably, the bottom of the spring is fixedly connected to the lower surface of the housing, and the top of the spring is fixedly connected to the lower surface of the disc. After the cam pushes the push rod, the push rod moves downward to push the material accumulated in the feed inlet into the forced mixer body to avoid material blockage. Then the spring resets and pushes the disc to move the push rod upward, so that the cam can continuously squeeze the push rod, so that the push rod moves up and down to push the material and prevent the material from being blocked in the feed inlet.

[0010] Preferably, the two gears mesh with each other, and the starting motor drives the rotating shaft to rotate. The meshing of the two gears causes the connecting rod to drive the cam to rotate.

[0011] Preferably, the top of the shell is conical, allowing the material to slide down the conical slope at the top of the shell, thus preventing the material from accumulating at the top of the shell.

[0012] Preferably, the striking mechanism includes a mounting block, a driven shaft, a pulley, a belt, a second cam, a second spring, and a striking block. The mounting block is fixedly installed on the right side of the feed inlet. The driven shaft is rotatably connected inside the mounting block. The pulley is fixedly installed on the outer side of the connecting rod and the front end of the driven shaft. The belt is sleeved on the outer side of the two pulleys. The second cam is fixedly installed on the outer side of the back of the driven shaft. One end of the second spring is fixedly installed on the inner wall of the second cam. The striking block is fixedly installed on the other end of the second spring.

[0013] Preferably, the second cam has an internal mounting groove, and the second spring and the striking block are installed in the mounting groove. The striking block can slide along the mounting groove. When the driven shaft drives the second cam to rotate, the striking block will collide with the side wall of the feed inlet, thereby causing the feed inlet to vibrate and causing the material attached to the inner wall of the feed inlet to fall off. At the same time, the striking block squeezes the second spring to slide along the mounting groove, avoiding excessive impact from the striking block on the feed inlet and damage to the feed inlet.

[0014] Preferably, the mounting block has mounting holes inside, and the driven shaft is mounted in the mounting block through bearings, with the mounting block providing support for the driven shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The anti-blocking device for the feed inlet of the forced mixer for intermediate refractory material preparation is provided by setting a pushing mechanism. The motor is started to drive the rotating shaft to rotate, and two gears mesh with each other, so that the connecting rod drives the cam to rotate. When the cam rotates, the cam will squeeze the push rod, so that the push rod moves downward and pushes the material accumulated in the feed inlet into the body of the forced mixer, thus avoiding material blockage.

[0017] 2. The anti-blocking device for the feed inlet of the forced mixer for preparing intermediate refractory materials is provided by setting a knocking mechanism. When the connecting rod rotates, it works with the pulley and belt to drive the driven shaft to rotate. At this time, the knocking block will collide with the side wall of the feed inlet, thereby causing the feed inlet to vibrate and causing the material attached to the inner wall of the feed inlet to fall off, thus preventing the material from accumulating on the inner wall of the feed inlet.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Due to the existing technology's tendency for the feed inlet to become clogged, affecting the normal operation of the mixer and reducing production efficiency, please refer to [the relevant documentation / reference]. Figures 1-5 This embodiment provides an anti-clogging device for the feed inlet of a forced mixer used in the preparation of tundish refractory materials. The device pushes material accumulated in the feed inlet into the forced mixer body, preventing blockage. The anti-clogging device includes a forced mixer body 1 and a feed inlet 2. The feed inlet 2 is installed on the top of the forced mixer body 1. Anti-clogging devices are provided inside and outside the feed inlet 2, including a pushing mechanism and a striking mechanism.

[0027] The pushing mechanism is located inside the feed inlet 2, and the striking mechanism is located outside the feed inlet 2.

[0028] The feeding mechanism includes a fixed rod 301, a housing 302, a connecting rod 303, a support platform 304, a motor 305, a rotating shaft 306, a gear 307, a cam 308, a push rod 309, a disc 310, and a spring 311. The fixed rod 301 is fixedly installed on the left and right sides of the inner wall of the feed inlet 2. The housing 302 is fixedly installed between the two fixed rods 301. The top of the housing 302 is conical, allowing the material to slide down along the conical slope at the top of the housing 302, preventing the material from accumulating at the top of the housing 302. The connecting rod 303 is rotatably connected to the inside of the housing 302 and one end penetrates through the housing. Body 302 extends to the outside of inlet 2. Support platform 304 is fixedly installed on the top of forced mixer body 1, located in front of inlet 2. Motor 305 is fixedly installed on the top of support platform 304. Motor 305 is model YZH-30-2. Rotary shaft 306 is fixedly installed on the output end of motor 305. Gear 307 is fixedly installed on the outside of rotating shaft 306 and connecting rod 303. The two gears 307 mesh with each other. By starting motor 305, rotating shaft 306 is driven to rotate, and the two gears 307 mesh with each other, thereby causing connecting rod 303 to drive cam 308 to rotate. Wheel 308 is fixedly installed on the outside of connecting rod 303 and inside housing 302. Push rod 309 is slidably installed inside housing 302. The bottom of push rod 309 is a tapered push head with a cone angle of 60-90° for easy insertion into the material pile. Disc 310 is fixedly installed on the top of push rod 309. Spring 311 is installed inside housing 302 and on the outside of push rod 309. The bottom of spring 311 is fixedly connected to the lower surface of the inside of housing 302, and the top of spring 311 is fixedly connected to the lower surface of disc 310. After cam 308 presses against push rod 309, push rod 309... 9. Moving downwards pushes the material accumulated in the feed inlet 2 into the forced mixer body 1 to avoid material blockage. Then, the spring 311 returns to its original position and pushes the disc 310 to move the push rod 309 upwards, so that the cam 308 can continuously squeeze the push rod 309, causing the push rod 309 to move up and down to push and tamp the material, preventing the material from blocking the feed inlet 2. The spring 311 is a cylindrical helical compression spring with a wire diameter of 3-5mm, an effective number of 6-10 turns, and a spring force range of 200-300N, ensuring that the push rod 309 can return to its original position stably and does not obstruct the squeezing action of the cam 308.

[0029] Example 2:

[0030] Based on Example 1, please refer to Figures 1-5To prevent material from adhering to the inner wall of the feed inlet 2 and to facilitate material discharge, this device is also equipped with a striking mechanism. The striking mechanism includes a mounting block 401, a driven shaft 402, a pulley 403, a belt 404, a second cam 405, a second spring 406, and a striking block 407. The mounting block 401 is fixedly installed on the right side of the feed inlet 2, and a mounting hole is provided inside the mounting block 401. The driven shaft 402 is installed in the mounting block 401 through a bearing, and the mounting block 401 supports the driven shaft 402. The driven shaft 402 is rotatably connected to the inside of the mounting block 401. The pulley 403 is fixedly installed on the outer side of the connecting rod 303 and the front end of the driven shaft 402. The belt 404 is sleeved on the outer side of the two pulleys 403. The second cam 405 is fixedly installed on the outer side of the back of the driven shaft 402, and a mounting groove is provided inside the second cam 405. Spring 406 and striking block 407 are installed in the mounting groove, and striking block 407 can slide along the mounting groove. When driven shaft 402 drives cam 405 to rotate, striking block 407 will collide with the side wall of feed port 2, thereby causing feed port 2 to vibrate and shake off the material attached to the inner wall of feed port 2. At the same time, striking block 407 squeezes spring 406 to slide along the mounting groove, avoiding excessive impact of striking block 407 on feed port 2 and damage to feed port 2. One end of spring 406 is fixedly installed on the inner wall of cam 405, and striking block 407 is fixedly installed on the other end of spring 406. The material of striking block 407 is polyurethane or nylon, with a hardness of Shore D60-80 and a weight of 50-100g, to ensure that the striking force is moderate, shaking off the material without damaging feed port 2.

[0031] In operation, the materials required for the preparation of tundish refractory are added to the forced mixer body 1 through the feed inlet 2. The forced mixer body 1 agitates the materials, thus preparing the tundish refractory. When the feed inlet 2 becomes blocked, the motor 305 is started, driving the rotating shaft 306 to rotate. This, in conjunction with the two gears 307, causes the connecting rod 303 to drive the cam 308 to rotate. As the cam 308 rotates, it presses against the push rod 309, causing the push rod 309 to move downwards and push the material accumulated in the feed inlet 2 into the forced mixer. Inside the main body 1, to prevent material blockage, the spring 311 then resets and pushes the disc 310 to move the push rod 309 upward, so that the cam 308 can continuously squeeze the push rod 309, causing the push rod 309 to move up and down to push and tamp the material, preventing the material from blocking the feed inlet 2. At the same time as the connecting rod 303 rotates, it works with the pulley 403 and belt 404 to drive the driven shaft 402 to rotate. At this time, the striking block 407 will collide with the side wall of the feed inlet 2, thereby causing the feed inlet 2 to vibrate, causing the material attached to the inner wall of the feed inlet 2 to fall off, preventing the material from accumulating on the inner wall of the feed inlet 2.
