Description

TECHNICAL FIELD

[0001] The utility model relates to smelting equipment technical field, concretely is a kind of slag salvaging device for crude lead refining. BACKGROUND

[0002] In the crude lead refining process, due to the high impurity content in crude lead, fire refining of crude lead is needed before electrolysis to remove copper, tin, zinc and other impurities in crude lead. In the process of crude lead fire refining, slagging of impurities in crude lead is carried out by adding copper removal agent and oxides, and then the impurities are removed. Therefore, different impurity slag will be produced in the lead pot. Generally, about 10% of slag needs to be salvaged during the crude lead refining process. Currently, slag is mainly salvaged by manual operation using a slag salvaging spoon. This method has high labor intensity, low positioning accuracy, and exposes the operator to a high-temperature lead liquid environment at close range. The overall efficiency of slag salvaging is low and the safety is poor. The efficiency and safety of slag salvaging operation directly affect the production efficiency.

[0003] Various mechanized solutions have been proposed in the prior art. For example, Chinese patent CN109807317A uses a spiral slag salvaging mechanism in combination with a water circulation dust suppression system to transport lead slag through a spiral shaft and suppress dust. However, this solution has a complex structure and requires continuous water supply, which can easily cause secondary pollution by water vapor in a high-temperature environment. In addition, the friction between the spiral blade and the slag body can cause equipment wear and tear. Chinese patent CN221522726U proposes an intelligent slag salvaging device driven by hydraulic pressure, which can achieve automatic operation through remote control. However, the hydraulic system has a response delay, and the oil line sealing reliability decreases in a high-temperature environment, resulting in an increased maintenance frequency. It can be seen that the current slag salvaging equipment has a complex structure and high maintenance cost. Therefore, there is an urgent need to develop a slag salvaging device with a simple structure, low maintenance cost, high safety, and high salvaging efficiency. SUMMARY

[0004] To solve the problems in the prior art, a slag salvaging device with a simple structure, low maintenance cost, high safety, and high salvaging efficiency is provided. The present invention proposes the following technical solutions:

[0005] The application relates to a slag salvaging device for crude lead refining, characterized in that the device comprises a lead pot, a lead pot stirring frame, a lead pot stirring power device, a travelling crane, a subsidence type slag salvaging device, a lead pot stirring paddle and a lead slag temporary storage hopper, the lead slag temporary storage hopper is placed on the ground independently of the lead pot, the lead pot stirring power device is connected with the lead pot stirring paddle, the lead pot stirring power device is arranged on the lead pot stirring frame, and the lead pot stirring paddle is arranged in the lead pot; the subsidence type slag salvaging device comprises a subsidence type slag salvaging disc slag collecting hopper provided with filtering holes, an L-shaped slag collecting hopper fixed handle, a lifting lug and a hollow telescopic T-shaped handle, the vertical side of the slag collecting hopper fixed handle is fixedly connected with the subsidence type slag salvaging disc slag collecting hopper, the horizontal side is arranged above the subsidence type slag salvaging disc slag collecting hopper and is inserted into the telescopic T-shaped handle, a fixing bolt is tightly pressed on the slag collecting hopper fixed handle through the surface of the telescopic T-shaped handle and is fixedly screwed through a fixing nut, and the lifting lug is fixed on the horizontal side of the slag collecting hopper fixed handle; and the hook of the travelling crane is hung in the lifting lug.

[0006] Further, the subsidence type slag salvaging disc slag collecting hopper comprises a bottom surface and three vertical edges higher than the bottom surface, and the vertical side of the slag collecting hopper fixed handle is fixedly connected with the middle edge of the subsidence type slag salvaging disc slag collecting hopper.

[0007] Further, a second filtering surface parallel to the bottom surface is fixedly arranged at the middle position of the three edges of the subsidence type slag salvaging disc slag collecting hopper, and the filtering holes on the second filtering surface are staggered with the filtering holes on the bottom surface.

[0008] Further, the filtering holes of the subsidence type slag salvaging disc slag collecting hopper are not larger than 1cm in diameter.

[0009] Further, the opening direction of the lifting lug faces the direction of the lead slag temporary storage hopper.

[0010] Further, the hook of the travelling crane is a one-way inward opening ring-shaped lock buckle.

[0011] The application has the following beneficial effects:

[0012] (1) The slag salvaging device is simple in structure, the length of the slag salvaging device can be flexibly adjusted according to the actual situation of the slag liquid surface, the length of the telescopic T-shaped handle can be adjusted according to the depth of the slag layer in the lead pot, the horizontal distance and other conditions when the operator is salvaging the slag, the sinking depth of the subsidence type slag salvaging disc slag collecting hopper can be conveniently adjusted, the precision and efficiency of salvaging the slag are improved, and the design of the double filtering surfaces of the device can further improve the efficiency of salvaging the slag.

[0013] (2)Meanwhile, the device replaces the most laborious process of lifting the slag in the traditional process of salvaging the slag by the travelling crane, and since the position of the travelling crane is higher, only a small amount of power is needed to lift the salvaging shovel and move the salvaging shovel in the horizontal direction, which greatly reduces the labor intensity, and the travelling crane hook is specially provided with an anti-unhooking device (ring-shaped lock), so as to ensure the safety of the operation;

[0014] (3)Moreover, since the structure of the sinking type salvaging disc slag collecting hopper is set, it can realize automatic overturning and slag unloading by loosening the handle, which reduces the safety risk.

[0015] Overall, the scheme provides a salvaging device with simple structure, low maintenance cost, high safety and high salvaging efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0022] In one embodiment, a slag skimming device for refining crude lead comprises: a lead pot 1, a lead pot stirring frame 2, a lead pot stirring power device 3, a travelling crane 4, a sinking slag skimming device 5, a lead pot stirring paddle 6, and a lead slag temporary storage hopper 8. The lead pot 1 is composed of a pot bottom and a pot body, which are welded together using an X-shaped welding bevel. The lead pot temporary storage hopper 8 is placed on the ground 7 separately from the lead pot 1. The lead pot stirring power device 3 is connected to the lead pot stirring paddle 6, and is placed on the lead pot stirring frame 2. The lead pot stirring paddle 6 is inserted into the lead pot 1.

[0023] The sinking slag skimming device 5 comprises a sinking slag skimming disc slag collecting hopper 501 with filter holes, an L-shaped slag collecting hopper fixed handle 502, a lifting lug 503, and a hollow telescopic T-shaped handle 504. The sinking slag skimming disc slag collecting hopper 501 has a size of 0.6m*0.6m, and comprises a bottom surface and three vertical edges higher than the bottom surface and fixed to three edges of the bottom surface. The height of the edges is 0.1m. A second filter surface parallel to the bottom surface is fixed to the three edges of the sinking slag skimming disc slag collecting hopper 501. The filter holes on the second filter surface and the filter holes on the bottom surface are staggered with each other. The diameter of all the filter holes is 1cm.

[0024] The vertical edge of the slag collecting hopper fixed handle 502 is fixedly connected to the middle edge of the sinking slag skimming disc slag collecting hopper 501 by welding. The horizontal edge is located above the sinking slag skimming disc slag collecting hopper 501 and is inserted into the telescopic T-shaped handle 504. A fixed bolt 506 is tightly pressed on the slag collecting hopper fixed handle 502 through the surface of the telescopic T-shaped handle 504, and is fixedly screwed by a fixed nut 505. The lifting lug 503 is fixedly welded to the horizontal edge of the slag collecting hopper fixed handle 502. The opening direction of the lifting lug 503 faces the direction of the lead slag temporary storage hopper 8. The thickness of the lifting lug is 3cm. A circular lifting hole is arranged on the lifting lug, and the diameter of the lifting hole is 15cm. The hook of the travelling crane 4 is hung in the lifting lug 503. The hook is a one-way inwardly opening ring-shaped lock.

[0025] The lead pot stirring frame 2, the sinking slag skimming disc slag collecting hopper 501, the slag collecting hopper fixed handle 502, the lifting lug 503, and the telescopic T-shaped handle 504 are all made of 304 stainless steel.

[0026] Working principle: in actual use, the crane 4 (suspended on the top of the room) is adjusted to be directly above the lifting lug 503 to prevent the submerged slag collecting bucket 501 from moving greatly when lifting. When collecting slag, the crane 4 is connected with the lifting lug 503 through a hook, one end of the telescopic T-shaped handle 504 away from the submerged slag collecting bucket 501 is lifted, the submerged slag collecting bucket 501 is at a certain angle with the horizontal line, the submerged slag collecting bucket 501 is adjusted to extend into the lead liquid surface 9, the operator holds the telescopic T-shaped handle 504 at the far end without moving, the submerged slag collecting bucket 501 is lifted to leave the lead liquid surface 9 after the slag is scooped, the operator holds the telescopic T-shaped handle 504 at the far end to maintain the submerged slag collecting bucket 501 horizontally, because the diameter of the filter hole of the submerged slag collecting bucket 501 is smaller than the particle size of the lead slag, therefore, when the submerged slag collecting bucket 501 leaves the lead liquid surface 9, the lead liquid leaks from the filter hole, the lead slag is collected, the submerged slag collecting device 5 can adjust the length of the telescopic T-shaped handle 504 and the fixed handle 502 of the collecting bucket as a whole according to the slag liquid surface. The direction of the lifting lug is consistent with the direction of the lead slag temporary storage tank 8, such a design is beneficial to maintaining the stability of the submerged slag collecting device 5 during the lifting and transportation of the crane and facilitating subsequent unloading, the submerged slag collecting bucket 501 is adjusted to be above the lead slag temporary storage tank 8, the operator releases the telescopic T-shaped handle 504 at the far end and adjusts the crane 4 to make the collecting bucket 501 tilt, the lead slag falls into the lead slag temporary storage tank 8, and a cycle of slag collecting process is completed. The operator only assists in maintaining the stability of the device during the whole cycle process and can be far away from the lead pot, the crane 4 mainly performs force exertion and movement operation, which greatly reduces the labor intensity and safety risk. In addition, the fixed handle 502 of the collecting bucket provides an additional operation point for the operator, when the submerged slag collecting bucket 501 needs to be assisted (such as slightly adjusted or cleaned after collecting slag), the operator can operate by holding the fixed handle 502 of the collecting bucket.
