[0002] In the normal production process of calcium carbide furnace, as the calcium carbide furnace continues to produce, the electrodes are also consumed. In order to ensure safe and stable production and to ensure sufficient electrode working end length, it is necessary to add electrode paste regularly.

[0003] Existing electrode paste adding method: the operator uses an electric hoist to lift the packaged electrode paste to the top of the electrode barrel, and the operator uses a knife to cut the bottom of the packaging bag to make the required electrode paste fall into the electrode barrel. This operation requires the operator to have a high sense of responsibility and safety awareness. If the electrode paste is accidentally spilled outside the electrode barrel and connected to adjacent equipment, it will cause equipment damage or other accidents due to sparks, or personnel may fall and get injured, or be hit by objects during operation.

[0004] Therefore, a device for unloading electrode paste for calcium carbide furnace is provided to solve the problems raised in the above background technology. Utility Model Content

[0005] The technical problem solved by the utility model is how to realize automatic unloading of electrode paste.

[0006] The utility model solves the above-mentioned technical problem through the following technical solution: an electrode paste unloading device for a calcium carbide furnace, comprising a paste unloading barrel and a paste unloading assembly, wherein one end of the paste unloading barrel has a feed port, and the other end of the paste unloading barrel has a discharge port, and the paste unloading assembly passes through the feed port and is closed or separated from the discharge port.

[0007] The beneficial effect of the utility model is that the electrode paste is filled into the paste unloading barrel through the feed port, and then the discharge port is placed on the top of the electrode barrel. The staff uses a hoist to drive the paste unloading assembly, and the paste unloading assembly moves downward in the vertical direction by gravity, so that the paste unloading assembly is separated from the discharge port, and then the electrode paste in the paste unloading barrel can fall into the electrode barrel from the gap between the paste unloading assembly and the discharge port, realizing automatic unloading of the electrode paste.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a fixed tie rod, the two ends of which are respectively fixedly connected to the inner walls of the opposite sides of the glue unloading barrel, and the fixed tie rod has a first through hole, and the glue unloading assembly slides through the first through hole.

[0010] The beneficial effect of adopting the above further scheme is that when the hoist drives the paste unloading assembly, when the paste unloading assembly passes through the first through hole and moves downward in the vertical direction, it can ensure that the paste unloading assembly moves linearly downward in the vertical direction, avoiding the paste unloading assembly from deflecting during the movement.

[0011] Furthermore, the paste unloading assembly includes a paste unloading bucket, a pull rod and a pull ring, one end of the pull rod is fixedly connected to the pull ring, and the other end of the pull rod is fixedly connected to the paste unloading bucket, the pull rod passes through the feed port and the first through hole in sequence, and the paste unloading bucket is closed or separated from the discharge port.

[0012] The beneficial effect of adopting the above further solution is that the hoist drives the pull rod through the pull ring, and the pull rod moves upward in the vertical direction by gravity until the paste unloading bucket and the second through hole are closed, at which time, the electrode paste in the paste unloading bucket has no gap to fall to the outside. When the hoist drives the pull rod to move downward in the vertical direction, a gap is generated between the paste unloading bucket and the second through hole, and the electrode paste in the paste unloading bucket can fall to the outside through the gap.

[0013] Furthermore, the size of the paste unloading end surface of the paste unloading bucket is the same as the size of the discharge port.

[0014] The beneficial effect of adopting the above further solution is that the size of the paste unloading end surface of the paste unloading bucket is the same as the size of the discharge port, which can ensure that when the paste unloading bucket and the discharge port are in a closed state, no electrode paste will spill from the paste unloading barrel.

[0015] Furthermore, the paste unloading bucket is a hollow cone.

[0016] The beneficial effect of adopting the above further solution is that the hollow cone can make the electrode paste fall evenly into the electrode barrel.

[0017] Furthermore, the length of the pull rod along the vertical direction is greater than the height of the paste unloading barrel along the vertical direction.

[0018] The beneficial effect of adopting the above further solution is that the height of the pull rod in the vertical direction is greater than the height of the paste unloading barrel in the vertical direction, which can facilitate the hoist to drive the pull rod to move downward in the vertical direction into the electrode barrel.

[0019] Furthermore, it also includes a bottom plate, the discharge port is fixedly connected to the bottom plate, the bottom plate has a second through hole matching the discharge port, and the size of the second through hole is the same as the size of the discharge port.

[0020] The beneficial effect of adopting the above further solution is that the second through hole and the discharge port are of the same size, which can prevent the electrode paste from spilling outside the electrode barrel during the falling process.

[0021] Furthermore, the length of the bottom plate in the horizontal direction is greater than the diameter of the paste unloading barrel.

[0022] Furthermore, it also includes a plurality of support rods, which are evenly distributed along the circumference of the glue unloading barrel, one end of the support rod is fixedly connected to the side wall of the glue unloading barrel, and the other end of the support rod is fixedly connected to one end of the bottom plate.

[0023] The beneficial effect of adopting the above further solution is: providing symmetrical supporting force to the paste unloading barrel, thereby preventing the bottom plate from being damaged due to excessive weight of the electrode paste in the paste unloading barrel.

[0024] Furthermore, the feed port and the discharge port are both circular holes, and the diameter of the feed port is greater than the diameter of the discharge port.

[0025] The beneficial effect of adopting the above further solution is that the diameter of the feed port is larger than the diameter of the discharge port, which makes it easier for the electrode paste manufacturer to fill the electrode paste. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] like Figure 1-Figure 5As shown, this embodiment provides an electrode paste unloading device for a calcium carbide furnace, including a paste unloading barrel 1 and a paste unloading assembly 4, wherein one end of the paste unloading barrel 1 has a feed port 101, and the other end of the paste unloading barrel 1 has a discharge port 102, and the paste unloading assembly 4 passes through the feed port 101 and is closed or separated from the discharge port 102.

[0035] The electrode paste is filled into the paste unloading barrel 1 through the feed port 101, and then the discharge port 102 is placed on the top of the electrode barrel 6. The staff uses the hoist to drive the paste unloading assembly 4, and the paste unloading assembly 4 moves downward in the vertical direction by gravity, so that the paste unloading assembly 4 is separated from the discharge port 102, and then the electrode paste in the paste unloading barrel 1 can fall into the electrode barrel 6 from the gap between the paste unloading assembly 4 and the discharge port 102, realizing automatic unloading of the electrode paste.

[0036] Specifically, the diameter of the feed port 101 is the same as the diameter of the paste unloading barrel 1. The paste unloading barrel 1 can be made of stainless steel.

[0037] Among them, in this embodiment, the glue unloading barrel 1 is a non-standard round barrel. According to actual needs, the glue unloading barrel 1 can be set to a barrel of other shapes, such as a frustum-shaped barrel with a long upper bottom and a short lower bottom.

[0038] On the basis of the above scheme, it also includes a fixed tie rod 3, the two ends of which are respectively fixedly connected to the inner walls of the opposite sides of the glue unloading barrel 1, and the fixed tie rod 3 has a first through hole. The glue unloading assembly 4 slides through the first through hole and is closed or separated from the bottom plate 2.

[0039] When the hoist drives the paste unloading assembly 4, the paste unloading assembly 4 passes through the first through hole and moves downward in the vertical direction, which can ensure that the paste unloading assembly 4 moves linearly downward in the vertical direction, thereby avoiding deviation of the paste unloading assembly 4 during movement.

[0040] Specifically, the first through hole is located in the middle of the fixed reinforcement 3 .

[0041] Specifically, it can also include two fixed tie bars 3, both ends of which are fixedly connected to the inner walls of the paste unloading barrel 1 on opposite sides, and the two fixed tie bars 3 are perpendicular to each other, and the pull rod 402 slides through the intersecting holes of the two fixed tie bars 3.

[0042] Among them, the two fixed tie bars 3 can be set as a group of fixed tie bars, and the inner wall of the paste unloading barrel 1 can be provided with multiple groups of fixed tie bars at intervals along the vertical direction. The pull rod 402 passes through the intersecting holes of the multiple groups of fixed tie bars in sequence, which can improve the stability of the pull rod 402 in linear movement along the vertical direction.

[0043] On the basis of the above scheme, the paste unloading assembly 4 includes a paste unloading bucket 401, a pull rod 402 and a pull ring 403, one end of the pull rod 402 is fixedly connected to the pull ring 403, and the other end of the pull rod 402 is fixedly connected to the paste unloading bucket 401, the pull rod 402 passes through the feed port 101 and the first through hole, and the paste unloading bucket 401 is closed or separated from the discharge port 102.

[0044] The hoist drives the pull rod 402 through the pull ring 403, and the pull rod 402 moves upward in the vertical direction by gravity until the paste discharge bucket 401 and the second through hole are closed. At this time, the electrode paste in the paste discharge barrel 1 has no gap to fall to the outside. When the hoist drives the pull rod 402 to move downward in the vertical direction, a gap is generated between the paste discharge bucket 401 and the second through hole, and the electrode paste in the paste discharge barrel 1 can fall to the outside through the gap.

[0045] Specifically, the paste unloading assembly 4 also includes two steel plates 404 and an insulating plate 405, wherein one end of one steel plate 404 is fixedly connected to the pull ring 403, and one end of the other steel plate 404 is fixedly connected to one end of the pull rod 402, and the two steel plates 404 are fixedly connected by bolts.

[0046] The insulating plate 405 is fixed between the two steel plates 404 .

[0047] In addition, if Figure 4 As shown, the paste unloading bucket 401 and the second through hole are in a closed state, and the electrode paste in the paste unloading barrel 1 cannot fall to the outside;

[0048] like Figure 5 As shown, when the hoist hoists the pull rod 402 and the paste unloading bucket 401 as a whole through the pull ring 403 and moves downward in the vertical direction, the paste unloading bucket 401 is separated from the second through hole.

[0049] On the basis of the above solution, the size of the paste unloading end surface of the paste unloading bucket 401 is the same as the size of the discharge port 102 .

[0050] The size of the paste unloading end surface of the paste unloading bucket 401 is the same as that of the discharge port 102 , which can ensure that when the paste unloading bucket 401 and the discharge port 102 are in a closed state, no electrode paste will spill from the paste unloading barrel 1 .

[0051] Specifically, the end of the paste unloading bucket 401 away from the pull ring 403 is a paste unloading end surface.

[0052] The length of the paste unloading end surface of the paste unloading bucket 401 along the horizontal direction is equal to the length of the second through hole along the horizontal direction.

[0053] In addition, the end surface size of the paste unloading bucket 401 may also be larger than the size of the discharge port 102 to prevent the paste unloading bucket 401 from moving into the paste unloading barrel 1 when moving in the vertical direction.

[0054] On the basis of the above solution, the paste unloading bucket 401 is a hollow cone.

[0055] The hollow cone allows the electrode paste to evenly fall into the electrode barrel 6 .

[0056] Alternatively, the paste unloading bucket 401 may be a hollow polyhedron of other shapes, such as a hollow cylinder, a hollow cube, and a hollow cuboid.

[0057] On the basis of the above solution, the length of the pull rod 402 along the vertical direction is greater than the height of the paste unloading barrel 1 along the vertical direction.

[0058] The height of the pull rod 402 along the vertical direction is greater than the height of the paste unloading barrel 1 along the vertical direction, which can facilitate the hoist to drive the pull rod 402 to move downward in the vertical direction into the electrode barrel 6.

[0059] On the basis of the above scheme, it also includes a bottom plate 2, the discharge port 102 is fixedly connected to the bottom plate 2, the bottom plate 2 has a second through hole matching the discharge port 102, and the size of the second through hole is the same as the size of the discharge port 102.

[0060] The second through hole and the discharge port 102 have the same size, which can prevent the electrode paste from spilling outside the electrode barrel 6 during the falling process.

[0061] Optionally, the discharge port 102 and the bottom plate 2 can be detachably connected, or the discharge port 102 and the bottom plate 2 can be integrally formed. When the discharge port 102 and the bottom plate 2 are integrally formed, the bottom plate 2 is connected to the bottom plate 2 through the second through hole.

[0062] The length of the second through hole along the horizontal direction is equal to the length of the discharge port 102 along the horizontal direction.

[0063] On the basis of the above solution, the length of the bottom plate 2 in the horizontal direction is greater than the diameter of the paste unloading barrel 1 .

[0064] On the basis of the above scheme, it also includes multiple support rods 5, which are evenly distributed along the circumference of the glue unloading barrel 1, one end of the support rod 5 is fixedly connected to the side wall of the glue unloading barrel 1, and the other end of the support rod 5 is fixedly connected to one end of the bottom plate 2.

[0065] A symmetrical supporting force is provided to the paste unloading barrel 1 to prevent the bottom plate 2 from being damaged due to excessive weight of the electrode paste in the paste unloading barrel 1 .

[0066] Specifically, in this embodiment, Figure 1As shown, it includes two support rods 5, and the two support rods 5 are symmetrically arranged on both sides of the paste unloading barrel 1.

[0067] Alternatively, the bottom plate 2 can be replaced by a square or rectangular fixing frame, one end of a support rod 5 is fixed to each of the four corners of the fixing frame, and the other end of the support rod 5 is fixedly connected to the side wall of the paste unloading barrel 1.

[0068] On the basis of the above solution, the feed port 101 and the discharge port 102 are both circular holes, and the diameter of the feed port 101 is greater than the diameter of the discharge port 102 .

[0069] The diameter of the feed port 101 is larger than the diameter of the discharge port 102 , which makes it easier for the electrode paste manufacturer to fill the electrode paste.

[0070] In this embodiment, when in use, first, the electrode paste is filled into the paste unloading barrel 1 through the feed port 101, and then the bottom plate 2 is placed on the top of the electrode barrel 6.

[0071] Secondly, the staff drives the hoist to move the pull rod 402 downward in the vertical direction through the pull ring 403, and at the same time, the paste unloading bucket 401 moves downward in the vertical direction by gravity, so that the paste unloading bucket 401 and the bottom plate 2 are in a separated state, so that the electrode paste in the paste unloading bucket 1 can evenly fall from the separation gap between the paste unloading bucket 401 and the bottom plate 2 into the electrode barrel 6. When the electrode paste in the electrode barrel 6 has reached the set paste unloading amount, the hoist is driven to drive the pull rod 402 to move upward in the vertical direction by gravity until the paste unloading bucket 401 and the bottom plate 2 are in a closed state, waiting for the next paste unloading operation.
