Description

Technical Field

[0001] The utility model belongs to the field of galvanizing process equipment, and particularly relates to a special shovel for zinc slag treatment in a hot-dip galvanizing tank. Background Technique

[0002] Hot dip galvanizing is one of the important means for anti-corrosion treatment of metal surfaces. During the treatment process, the steel materials that have undergone preliminary treatment are placed in a galvanizing tank for immersion galvanizing. The zinc liquid in the galvanizing tank is reused. After being used for a period of time, zinc slag often remains. In order to avoid the zinc slag from affecting the galvanized layer of the steel, it is necessary to regularly clean the zinc slag in the galvanizing tank.

[0003] Because the zinc liquid in the galvanizing tank needs to be maintained in a liquid state, the temperature is relatively high. During the zinc slag treatment process, only a shovel can be used to clean the zinc slag. Usually, a crane is used to lift the shovel and sink it into the zinc pot to fish out the zinc slag. Since it cannot be shaken, a large amount of zinc liquid often adheres to the surface of the zinc slag and is shoveled up and poured out together, resulting in waste of zinc liquid and invisibly increasing the production cost. For this reason, some targeted solutions have also been proposed in the prior art. For example, in the patent with the patent number "CN220099151U" and the name "A hot-dip galvanizing zinc pot cleaning shovel device", holes are mainly opened on the shovel body to allow the zinc liquid to flow out. However, the applicant found in the research that because the viscosity and surface tension of the zinc liquid are relatively large at this time, when it is shoveled up together with the zinc slag, it is not easy to filter out from the zinc slag, and even quickly adheres to the surface of the zinc slag and is poured out together. Therefore, this type of structure cannot substantially solve the above technical problems.

[0004] In addition, when using a shovel to perform a hanging shovel operation through a crane, the zinc slag is also likely to accumulate at the bottom edge of the galvanizing pot or galvanizing tank and is difficult to be shoveled up. Eventually, manual cleaning is still required, increasing the labor intensity of personnel and the harmful risk of operation. Content of the Utility Model

[0005] In view of this, the utility model provides a special shovel for zinc slag treatment in a hot-dip galvanizing tank to solve the problems in the prior art that zinc liquid is easily wasted during the zinc slag cleaning process, or the zinc slag in the galvanizing tank cannot be cleaned thoroughly.

[0006] Its technical solution is as follows:

[0007] A special shovel for zinc slag treatment in a hot-dip galvanizing tank includes a long handle and a shovel bucket. The bottom of the shovel bucket has filter holes. The key lies in that one end of the long handle has a support seat, the shovel bucket is movably supported on the support seat, and a pushing mechanism for driving the shovel bucket to reciprocate and slide is arranged between the long handle and the shovel bucket.

[0008] With the above solution, during the process of cleaning zinc dross, the swing mechanism can be used to make the bucket swing, so that the zinc liquid adhering to the zinc dross can be better filtered out through the filter holes, thereby retrieving the waste of zinc liquid. On the other hand, when there is less residual zinc dross, with the help of the swing mechanism at the end of the zinc tank, the chopping action of the bucket is completed, which can make the zinc dross easier to enter the bucket, improve the cleaning efficiency, and reduce the residual zinc dross.

[0009] Preferably, the support seat includes a rear baffle and at least two support plates. The bottom of the bucket is slidably matched with the support plates, and the long handle is fixedly connected to the rear baffle. With the above solution, it is convenient for the disassembly, replacement, etc. of the bucket.

[0010] Preferably, the support plate is wedge-shaped, and the thickness of its front end is less than that of the rear end. With the above solution, when the support plate is close to the bottom of the zinc tank or zinc pot, the bucket is generally in a state of tilting at the front end. Cooperating with the pushing action, it is more beneficial to shovel up the zinc dross.

[0011] Preferably, the swing mechanism includes an electric push rod and a connecting rod. The two ends of the connecting rod are respectively hinged to the bucket and the push rod of the electric push rod. The rear baffle is provided with an avoidance groove for the connecting rod to pass through. The avoidance groove is a strip-shaped groove and is arranged along the height direction of the rear baffle. With the above solution, the avoidance groove can limit the movement range of the connecting rod.

[0012] Preferably, there is an extension rod between the electric push rod and the connecting rod. One end of the extension rod is fixedly connected to the push rod of the electric push rod, and the other end is hinged to the connecting rod. With the above solution, after adding the extension rod, it can be replaced according to needs, adapt to different zinc liquid depths, etc., ensure that the electric push rod is above the liquid surface during use, can relatively reduce the sealing requirements, can extend the overall service life, and save costs, etc.

[0013] Preferably, the support plate is provided with a dovetail groove with an upward opening, and the bottom of the bucket is provided with a dovetail that cooperates with the dovetail groove. The end of the dovetail groove is open and is provided with a sealing plate installed in a detachable manner. With the above solution, it can ensure the smooth sliding of the bucket and prevent the zinc dross from invading.

[0014] Preferably, a diversion plate is provided at the position corresponding to the dovetail in the bucket. The diversion plate is wedge-shaped and is arranged along the depth direction of the bucket. The height of its front end is less than that of the rear end. With the above solution, during the process of simulating the chopping action, the diversion plate can better enter the bucket and prevent the zinc dross from accumulating in the corresponding area, resulting in the situation where the zinc liquid cannot be filtered out.

[0015] Preferably, the filter holes are conical holes, with the diameter of the top smaller than that of the bottom. With the above solution, when the temperature drops, the zinc liquid is more likely to adhere and fix on the object. For the filter holes of this shape, the zinc liquid can pass through and drop more easily, without adhering to the orifice, and at the same time, it also avoids the situation that the zinc slag leaks out due to the too large diameter of the top of the filter hole.

[0016] Preferably, the bucket has an inclined opening. With the above solution, the zinc slag can enter the interior of the bucket more easily and the spillage during hoisting can be reduced.

[0017] Preferably, it further includes a counterweight, which includes a counterweight frame and counterweight blocks. There is a sliding fit structure between the counterweight frame and the long handle, and a position adjustment mechanism for driving the counterweight to slide along the length direction of the long handle. With the above solution, during the cleaning process, by adjusting the position of the counterweight to make the counterweight close to the bucket, the bucket can sink to the bottom better, and the zinc slag can be shoveled up with the bucket sticking to the bottom. During the hoisting process, according to the approximate weight in the bucket, the counterweight is moved away from the bucket, which can better balance the forces at both ends of the long handle, improve the hoisting stability, prevent the tipping of the bucket, and reduce the operation risk, etc.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] By using the special shovel for zinc slag treatment in the hot-dip galvanizing tank provided by the present utility model, mainly by setting the movable bucket structure, it is convenient for the zinc liquid to filter out. At the same time, by simulating the action of the blunt shovel, the zinc slag at the end can be shoveled up better, reducing residues, etc., and it has excellent on-site practicability.

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Refer to Figures 1 to 10 The special shovel for zinc slag treatment in the hot-dip galvanizing tank shown, mainly includes a long handle 1 and a shovel bucket 2. As shown in the figure, the bottom of the shovel bucket 2 has filter holes 20. The key point of this application is that one end of the long handle 1 has a support seat 3, and the shovel bucket 2 is movably supported on the support seat 3. A pushing mechanism 4 for driving the shovel bucket 2 to reciprocate and slide is provided between the long handle 1 and the shovel bucket 2.

[0032] During specific implementation, the support seat 3 includes a rear baffle 30 and at least two support plates 31. As shown in the figure, the support plates 31 are fixedly connected to the rear baffle 30, the bottom of the shovel bucket 2 is in sliding fit with the support plates 31, and the long handle 1 is fixedly connected to the rear baffle 30. Specifically, the support plates 31 have dovetail grooves 310 with openings facing upwards, and the bottom of the shovel bucket 2 has dovetails 21 that cooperate with the dovetail grooves 310. The cooperation between the dovetails 21 and the dovetail grooves 310 can also prevent the shovel bucket 2 from separating from the support plates 31 when lifted. The ends of the dovetail grooves 310 are open, and a sealing plate 311 is installed in a detachable manner. The front end of the dovetail groove 310 is open for the convenience of loading the shovel bucket 2. Additionally, setting the sealing plate 311 can reduce or avoid zinc slag invading from the front open end during use, thereby affecting the sliding of the shovel bucket 2.

[0033] In this application, the pushing mechanism 4 mainly includes an electric push rod 40 and a connecting rod 41. The two ends of the connecting rod 41 are respectively hinged to the shovel bucket 2 and the push rod of the electric push rod 40. The rear baffle 30 has an avoidance groove 300 for the connecting rod 41 to pass through. The avoidance groove 300 is a strip-shaped groove and is arranged along the height direction of the rear baffle 30.

[0034] In this embodiment, an extension rod 42 is further provided between the electric push rod 40 and the connecting rod 41. One end of the extension rod 42 is fixedly connected to the push rod of the electric push rod 40, and the other end is hinged to the connecting rod 41. As shown in the figure, the long handle 1 is a hollow square tube structure and has an installation groove 11 with an opening facing downwards. Both the electric push rod 40 and the extension rod 42 are located in the installation groove 11, and a limiting portion 12 is provided at a position corresponding to the sliding stroke of the extension rod 42. The limiting portion 12 can limit the extension rod 42 to only slide along the length direction of the installation groove 11, thereby reducing the torsional force on the electric push rod 40.

[0035] In addition, as Figure 9 and Figure 10As shown, the support plate 31 is wedge-shaped, with the thickness of its front end less than that of the rear end. In this way, when the bottom of the support plate 31 is in close contact with the bottom of the galvanizing tank or galvanizing pot, the bucket 2 is actually in an inclined downward posture, thus better shoveling up the zinc dross at the bottom.

[0036] To prevent the zinc liquid or zinc dross inside the bucket 2 from entering the dovetail groove 310 below, no filter holes 20 are provided at the corresponding positions inside the bucket 2, and a diversion plate 22 is provided at the corresponding positions. As shown in the figure, the diversion plate 22 is a wedge-shaped thin sheet, which gradually becomes higher along the depth direction of the bucket 2, and the height of its front end is less than that of the rear end. In the actual implementation process, its length accounts for about half of the depth.

[0037] In this embodiment, the filter hole 20 is a conical hole, and the diameter of its top is less than that of the bottom, which can increase the adhesion of the zinc liquid in the filter hole 20 under the action of surface tension and improve the zinc liquid filtering effect.

[0038] The interior of the bucket 2 of this application is generally similar to the traditional structure, with its top and front end open, but the front end of the bucket 2 in this embodiment is a beveled opening. As shown in the figure, the bucket 2 has side plates 23, and the front end of the side plates 23 inclines inward and downward at the same time.

[0039] To better maintain its stability during the process of lifting and transporting the bucket, a counterweight 5 is usually provided on the long handle 1. As shown in the figure, the counterweight 5 generally includes a counterweight frame 50 and counterweight blocks 51. In this application, to further improve the use safety, the counterweight 5 is set as an adjustable structure. There is a sliding fit structure between the counterweight frame 50 and the long handle 1, and a position adjustment mechanism 7 for driving the counterweight 5 to slide along the length direction of the long handle 1.

[0040] Specifically, the position adjustment mechanism 7 mainly includes a driving motor 70, a rack 72 and a guide rail 73. As shown in the figure, the rack 72 and the guide rail 73 are fixedly arranged side by side on the upper side of the long handle 1, the driving motor 70 is fixedly arranged on the counterweight frame 50, and a gear 71 meshing with the rack 72 is provided on its motor shaft. Correspondingly, the counterweight frame 50 has a slider 74 slidingly fitted with the guide rail 73. In this way, when the driving motor 70 works, the whole counterweight 5 can be driven to slide and adjust the position along the guide rail 73. In this embodiment, a double-axis guide rail is preferably used as the guide rail 73, and a slider 74 is provided on each of the front and rear sides of the counterweight frame 50, which can further improve the stability of the counterweight 5 during sliding. During implementation, the cable of the driving motor 70 can be installed on the upper side of the long handle 1 by using a drag chain structure, and the cable of the electric push rod 40 can be directly passed through the long handle 1.

[0041] To cooperate with the cleaning of the hanging shovel, in this embodiment, lifting lugs A24 are provided on both the left and right sides of the bucket 23, and a rigid hanger 6 is provided as a counterweight, and a lifting lug B10 is provided at the tail end of the long handle 1.

[0042] Reference Figures 1 to 10The special shovel for treating zinc dross in the hot-dip galvanizing tank shown is usually lifted by a crane. During use, two independent cranes are used to hook the rigid fixture 6 and the lifting lug B10 respectively through the hanging steel cables, and the special shovel can be lifted and moved into the hot-dip galvanizing tank. During this process, the counterweight 5 is in the balanced position.

[0043] After the special shovel enters the hot-dip galvanizing tank, the counterweight 5 moves towards the end where the bucket 2 is located. At this time, the overall center of gravity is close to the bucket 2, enabling the bucket 2 to better adhere to the bottom of the galvanizing tank. The two cranes move synchronously, dragging the bucket 2 to move along the bottom of the galvanizing tank to shovel the zinc dross into the bucket 2.

[0044] After shoveling a large amount of zinc dross, the special shovel is lifted as a whole by the crane. The counterweight 5 is adjusted to move backward to make the whole basically balanced. At the same time, the height below the hanging steel cable is controlled to make one end of the bucket 2 tilt upwards relatively. Then, the bucket 2 is reciprocally slid several times through the pushing mechanism 4, that is, the shaking of the zinc dross is realized, making the zinc liquid attached inside easier to filter out through the filter holes 20, thereby reducing the waste of zinc liquid. Finally, it is moved to a designated location to pour out the zinc dross in the bucket 2.

[0045] After multiple cleanings, most of the zinc dross has been shoveled out. In the later stage of cleaning, the zinc dross is basically piled up at the end of the galvanizing tank. When the bucket 2 is close to the bottom wall of the galvanizing tank, the pushing mechanism 4 is used to drive the bucket 2 to reciprocally slide, simulating the action of a chopping shovel, which can better shovel up the residual zinc dross at the end, thereby improving the completion degree of mechanical cleaning and reducing the labor intensity of personnel, etc.

[0046] Finally, it should be noted that the above description is only the preferred embodiment of the present utility model. Those of ordinary skill in the art, under the inspiration of the present utility model and without violating the purpose and claims of the present utility model, can make various similar representations, and such transformations all fall within the protection scope of the present utility model.
