Description

Technical Field

[0001] The utility model relates to the technical field of graphite carbon brick processing, and more specifically, it relates to a raw material selection device for processing corrosion-resistant graphite carbon bricks. Background Art

[0002] Carbon bricks are made of coke, anthracite or graphite and tar as raw materials. After mixing, forming, and burning to 1450℃ in a reducing flame, they are a kind of carbon refractory material. They are resistant to erosion by molten metal and various slags, but are easily oxidized. They are used to build the bottom and belly of blast furnaces.

[0003] In order to ensure the production quality of existing carbon bricks, it is necessary to screen and select the carbon bricks during production, so a selection device is needed. However, the inventors have found that most of the existing raw material selection devices have the following problems: In the existing process of screening and selecting carbon brick raw materials, the raw materials are generally transported or poured onto the screen by an elevator or an auger conveyor bucket. Since the raw materials fall straight down onto the screen, it is easy for too much raw material to accumulate on the screen. Therefore, it is difficult for the screen to shake off the piled raw materials when screening the raw materials. If these piles of raw materials are not broken up in time, the raw material piles will become larger and larger, thereby affecting the screening and selection efficiency of the vibrating screen for the raw materials. When the problem of accumulation occurs on the screen, the raw materials on the screen need to be manually moved to diffuse the distribution of the raw materials, thereby increasing the workload of the staff. In response to the above problems, the inventors have designed a raw material selection device for processing corrosion-resistant graphite carbon bricks. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a raw material selection device for corrosion-resistant graphite carbon brick processing, which uses a toggle rod to toggle the corrosion-resistant graphite carbon brick raw material in an S-shaped path. When the corrosion-resistant graphite carbon brick raw material is poured onto the screen, the toggle rod swinging back and forth can push the accumulated raw material apart. This method does not require manual to push apart the corrosion-resistant graphite carbon brick raw material, thereby improving the efficiency of selecting the corrosion-resistant graphite carbon brick raw material.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A raw material selection device for processing corrosion-resistant graphite carbon bricks includes a shell and a base frame, wherein a connecting shaft is rotatably connected between the inner walls on both sides of the shell, the connecting shaft is close to the top of the inclined surface of the screen, the outer surface of the connecting shaft is sleeved with a sleeve, and the lower surface of the sleeve is fixedly connected with a plurality of toggle rods, one end of the connecting shaft rotates through the outer surface of the shell, and the end of the connecting shaft located outside the shell is fixedly sleeved with a gear, the side of the gear is meshingly connected with a rack, the lower surface of the rack is fixedly installed with a fixing plate, and the lower side of the fixing plate is fixedly installed on the outer surface of the base frame.

[0007] The utility model is further configured as follows: the base frame is arranged at the lower side of the shell, four buffer dampers are fixedly connected between the base frame and the shell, a vibration motor is installed at the bottom of the shell, and an inclined screen is installed in the shell.

[0008] The utility model is further configured as follows: a sleeve hole is opened on the sleeve, and the sleeve is slidably sleeved on the outer surface of the connecting shaft through the sleeve hole.

[0009] The utility model is further configured as follows: the outer surfaces on both opposite sides of the connecting shaft are fixedly connected with limiting sliders, and a limiting sliding groove is opened on the inner wall of the sleeve hole close to the limiting sliding groove, which extends out of the outer surface of the sleeve, and the limiting sliding groove slides in the limiting sliding groove.

[0010] The utility model is further configured as follows: a connecting slide rod is fixedly connected to a surface of one side of the sleeve facing the shell, and the other end of the connecting slide rod contacts the inner wall of the shell and slides.

[0011] The utility model is further configured as follows: a plurality of arc-shaped protrusions are fixedly connected to the inner wall of the shell, and the other end of the connecting slide rod is also in contact with the arc-shaped surface of the arc-shaped protrusion.

[0012] The utility model is further configured as follows: a spring is fixedly connected between a surface of one side of the sleeve away from the connecting slide rod and an inner wall of the shell body, and the spring is movably sleeved on the outer surface of the connecting shaft.

[0013] The utility model has the advantages that the corrosion-resistant graphite carbon brick raw materials are moved in an S-shaped path by the toggle rod. When the corrosion-resistant graphite carbon brick raw materials are poured onto the screen, the toggle rod swinging back and forth can push away the accumulated raw materials. This method does not require manual pushing away of the corrosion-resistant graphite carbon brick raw materials, thereby improving the efficiency of selecting the corrosion-resistant graphite carbon brick raw materials.

DETAILED DESCRIPTION

[0019] See also Figure 1-4 , the utility model provides the following technical solutions:

[0020] Specifically, it refers to a raw material selection device for processing corrosion-resistant graphite carbon bricks, including a shell 1 and a base frame 2, the base frame 2 is arranged on the lower side of the shell 1, four buffer dampers 3 are fixedly connected between the base frame 2 and the shell 1, a vibration motor 4 is installed at the bottom of the shell 1, and the vibration motor 4 is an existing known technology and will not be described in detail here. An inclined screen 5 is installed in the shell 1, so when it is necessary to select the raw materials of corrosion-resistant graphite carbon bricks, it is only necessary to pour these raw materials onto the top of the screen 5, and at the same time, the vibration motor 4 is started, so that the raw materials on the screen 5 are screened under the action of the shaking force, so that the raw materials of corrosion-resistant graphite carbon bricks can be selected;

[0021] Specifically, a connecting shaft 9 is rotatably connected between the inner walls of the two opposite sides of the shell 1, the connecting shaft 9 is close to the top of the inclined surface of the screen 5, the outer surface of the connecting shaft 9 is sleeved with a sleeve 10, and the lower surface of the sleeve 10 is fixedly connected with a plurality of toggle rods 11, one end of the connecting shaft 9 rotates through the outer surface of the shell 1, and the end of the connecting shaft 9 located outside the shell 1 is fixedly sleeved with a gear 8, the side of the gear 8 is meshed and connected with a rack 7, and the lower surface of the rack 7 is fixedly installed with a fixing plate 6, and the lower side of the fixing plate 6 is fixedly installed on the outer surface of the base frame 2;

[0022] When the vibration motor 4 is running, the spacing between the housing 1 and the base frame 2 will change. Since the rack 7 is restricted by the fixed plate 6, when the housing 1 floats up and down, the gear 8 slides on the surface of the rack 7, so that the teeth on the rack 7 can drive the gear 8 to rotate back and forth, so that the sleeve 10 rotates back and forth with the connecting shaft 9, so that the toggle rod 11 swings back and forth. Therefore, when the corrosion-resistant graphite carbon brick raw material is poured onto the screen 5, the toggle rod 11 swinging back and forth can push away the accumulated raw materials. In this way, there is no need to manually push away the corrosion-resistant graphite carbon brick raw material, which improves the efficiency of selecting the corrosion-resistant graphite carbon brick raw material;

[0023] Specifically, a sleeve hole 12 is provided on the sleeve 10, and the sleeve 10 is slidably sleeved on the outer surface of the connecting shaft 9 through the sleeve hole 12. The outer surfaces of the connecting shaft 9 on opposite sides are fixedly connected with limiting sliders 13. A limiting slide groove 14 is provided on the inner wall of the sleeve hole 12 close to the limiting slider 13. The limiting slide groove 14 extends out of the outer surface of the sleeve 10, and the limiting slider 13 slides in the limiting slide groove 14. Therefore, when the connecting shaft 9 rotates, the connecting shaft 9 can drive the sleeve 10 to rotate synchronously through the limiting slider 13;

[0024] Specifically, a connecting slide bar 16 is fixedly connected to a surface of the sleeve 10 facing the housing 1, and the other end of the connecting slide bar 16 contacts and slides with the inner wall of the housing 1. A plurality of arc-shaped protrusions 17 are fixedly connected to the inner wall of the housing 1, and the other end of the connecting slide bar 16 also contacts with the arc surface of the arc-shaped protrusion 17. A spring 15 is fixedly connected between a surface of the sleeve 10 away from the connecting slide bar 16 and the inner wall of the housing 1, and the spring 15 is movably sleeved on the outer surface of the connecting shaft 9.

[0025] When the sleeve 10 rotates back and forth, the connecting slide bar 16 slides synchronously on the inner wall of the shell 1. When the connecting slide bar 16 slides to the arc surface of the arc-shaped protrusion 17, the arc-shaped protrusion 17 will squeeze the connecting slide bar 16, so that the sleeve 10 moves to the side away from the arc-shaped protrusion 17. At the same time, the spring 15 is stressed and squeezed and contracted. When the connecting slide bar 16 moves out of the arc-shaped protrusion 17, the spring 15 will form a reverse thrust on the sleeve 10, so that the sleeve 10 moves to the initial position. In this way, the toggle rod 11 is in an S-shaped path to toggle the corrosion-resistant graphite carbon brick raw material, which further improves the toggle effect of the corrosion-resistant graphite carbon brick raw material and ensures the selection effect of the corrosion-resistant graphite carbon brick raw material.

[0026] In this embodiment, since the spring 15 itself has a certain elasticity, when the sleeve 10 rotates, the spring 15 will bend and deform to a certain extent, and the sleeve 10 will not be stuck.

[0027] The working principle of the raw material selection device for processing corrosion-resistant graphite carbon bricks provided by the utility model is as follows: when the corrosion-resistant graphite carbon brick raw materials need to be selected, these raw materials only need to be poured onto the top of the screen 5, and the vibration motor 4 is started at the same time, so that the raw materials on the screen 5 are screened under the action of the shaking force, and at the same time the gear 8 slides on the surface of the rack 7, so that the teeth on the rack 7 can drive the gear 8 to rotate back and forth, so that the sleeve 10 rotates back and forth with the connecting shaft 9, so that the toggle rod 11 swings back and forth, so when the corrosion-resistant graphite carbon brick raw materials are poured onto the screen 5, the toggle rod 11 swinging back and forth can push away the accumulated raw materials;

[0028] When the sleeve 10 rotates back and forth, the connecting slide rod 16 slides synchronously on the inner wall of the shell 1. When the connecting slide rod 16 slides to the arc surface of the arc-shaped protrusion 17, the arc-shaped protrusion 17 will squeeze the connecting slide rod 16, so that the sleeve 10 moves to the side away from the arc-shaped protrusion 17. At the same time, the spring 15 is stressed and squeezed and contracted. When the connecting slide rod 16 moves out of the arc-shaped protrusion 17, the spring 15 will form a reverse thrust on the sleeve 10, so that the sleeve 10 moves to the initial position. In this way, the toggle rod 11 is moved in an S-shaped path to toggle the corrosion-resistant graphite carbon brick raw material.
