Description

Technical Field

[0001] The invention relates to the technical field of mechanical slag scooping, in particular to a bucket wheel type slag scooping machine. Background Art

[0002] At present, the common environmental problems in the lead smelting industry are the low-altitude pollution problems and high-temperature hazards of the electric lead refining pot and the crude lead copper removal pot. The main pollutant is lead vapor ("lead smoke"). Since the crude lead copper removal pot is generally cold-stage crude lead and residual poles are put into the pot, a thick layer of copper slag is formed on the surface of the lead pot. In addition, the slag removal equipment for copper slag has always used slag removal pans or manual slag removal without improvement. The pot cover must be completely opened to remove the slag. Some equipment operating on the pot surface, such as mixers, slag removal pans, and lead pumps, frequently complete their own different operating processes in the pot, and most of the lead smoke generated also escapes into the workshop.

[0003] The existing spiral slag scoop machines and chain bucket slag scoop machines on the market cannot effectively concentrate the waste slag during operation and need to be transported for the second time. During the operation, a large amount of dust will be dispersed in the workshop. Therefore, even if ventilation and dust removal systems such as side suction hoods and dust collection devices are installed in the lead melting pot, the control of lead smoke basically has no significant effect, resulting in poor air environment in the lead melting pot area and high temperature of the slag scoop working conditions, which greatly affects the health of the operators. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a bucket wheel slag scooping machine to solve the problems in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bucket wheel slag dredger comprises two lifting brackets placed on the edge of a pot and a cantilever beam slidably arranged between the two lifting brackets, and also comprises:

[0006] A sealing cover is fixedly arranged on the top of the cantilever beam and is used to carry out the slag scooping work in a sealed condition;

[0007] A slag scooping mechanism is arranged inside the sealing cover, the slag scooping mechanism comprises an annular shell fixedly connected inside the sealing cover, a fixed shaft rotating with the inner wall of the sealing cover is arranged through the middle of the annular shell, a slag scooping plate is fixedly connected to the surface of the fixed shaft, a driving assembly is arranged on the front of the slag scooping plate, a slag filter bucket is fixedly arranged on the four sides of the slag scooping plate, and a circular hole is opened on the surface of the slag filter bucket, a slag loading bucket is opened on the outer surface of the annular shell, and a plurality of flaps are rotatably arranged on one side of the slag filter bucket close to the annular shell;

[0008] The anti-blocking component is arranged outside the filter residue hopper and is used for automatically cleaning the residue that blocks the circular hole.

[0009] Preferably, the driving assembly includes a reduction motor fixed above the cantilever beam, the output end of the reduction motor and the surface of the fixed shaft are fixedly connected with a sprocket, and a chain is transmission-connected between the surfaces of the two sprockets.

[0011] Preferably, a movable groove adapted to the outer shell is formed at the bottom of the movable plate, and the output end of the electric telescopic rod is fixedly connected to the inner wall of the movable groove.

[0012] Preferably, a hydraulic cylinder is fixedly connected to the top of the lifting bracket, and an output end of the hydraulic cylinder is fixedly connected to the bottom of the cantilever beam.

[0013] Preferably, a tensioning assembly is provided on the surface of the sealing cover, and the tensioning assembly includes a rotating shaft rotatably connected to the surface of the sealing cover, one end of the rotating shaft passing through the interior of the sealing cover is fixedly connected to a cam, and the side of the cam away from the rotating shaft is fixedly connected to a connecting shaft, and the surface of the connecting shaft is fixedly connected to a tensioning wheel.

[0014] Preferably, the tensioning wheel is located on the inner side of the chain, one end of the rotating shaft located outside the sealing cover is provided with a thread, and a nut is threadedly connected to the surface of the rotating shaft.

[0015] The present invention provides a bucket wheel type slag scooping machine, which has the following beneficial effects:

[0016] (1) The wheel bucket type slag scooping machine separates the lead liquid and waste slag in a closed space during the slag scooping process. Most of the lead vapor is collected by the sealing cover and sucked away by the dust removal interface, effectively reducing the escape of smoke and dust. The slag scooping plate drives the filter slag bucket to rotate along the outer circle of the slag loading bucket in the sealing cover, so that the slag is scooped and filtered through the filter slag bucket. When the filter slag bucket is at a certain angle, the flap is turned over to further filter the lead liquid and release the waste slag into the slag loading bucket, realizing low-pollution slag scooping operations on the pot surface without the need for secondary transfer, thereby improving the slag scooping efficiency.

[0017] (2) In the process of scooping slag from the bucket, the two rotating shafts of the bucket rotate under the drive of the gear assembly. The rotating shaft drives the knocking ball to move back and forth through the support rod, continuously knocking the outer side of the bucket, so as to shake out the residue in the circular hole of the bucket, reduce the difficulty of cleaning, and prevent the bucket from being blocked and affecting the scooping efficiency.

[0018] (3) In the bucket wheel slag loader, when the reduction motor drives the chain for transmission, the nut is loosened and then the cam is driven to rotate. The cam and the tensioning wheel are eccentrically arranged so that the cam cooperates with the tensioning wheel to tighten the chain to prevent the chain from loosening during use, which may cause problems such as chain skipping and slipping.

[0040] Based on Example 1, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, the specific improvements are as follows: the anti-blocking component includes a frame 8 fixed to one side of the surface of the slag tray 43, the upper side and the lower side of the inner wall of the frame 8 are rotatably connected to the rotating shaft 9, the middle parts of the two rotating shafts 9 are fixedly connected to the gear 10, the inner wall of the frame 8 is fixedly connected to the shell 11, the shell 11 is made of high temperature resistant metal material, used to protect the electric push rod 12, and the inner wall of the shell 11 is fixedly connected to the electric push rod 12, the electric push rod 12 is used to drive the movable plate 13 to reciprocate, and the outer side of the shell 11 is provided with a movable plate through the sliding block 13, and the top and bottom of the movable plate 13 are fixedly connected with teeth 14 meshing with the gear 10, the surfaces of the two rotating shafts 9 are fixedly connected with a plurality of support rods 15, the support rods 15 are evenly distributed on the outside of the filter residue bucket 44, and the surfaces of the support rods 15 are fixedly connected with a plurality of knocking balls 16, the knocking balls 16 have different sizes, which are convenient for contacting with the surface of the filter residue bucket 44 when moving, thereby improving the cleaning effect, the bottom of the movable plate 13 is provided with a movable groove 17 adapted to the outer shell 11, and the output end of the electric push rod 12 is fixedly connected to the inner wall of the movable groove 17.

[0041] Through the arrangement of the above structure, the knocking ball 16 moves back and forth to continuously knock the outer side of the filter residue bucket 44, so as to shake out the residue in the circular hole 45, reduce the cleaning difficulty, and prevent the filter residue bucket 44 from being blocked and affecting the residue scooping efficiency.

[0042] Embodiment 3

[0043] In conjunction with Example 1 and Example 2, please refer to Figure 1 , Figure 6 and Fig.10 As shown, the specific improvements are as follows: a tensioning assembly is provided on the surface of the sealing cover 3, the tensioning assembly includes a rotating shaft 19 rotatably connected to the surface of the sealing cover 3, one end of the rotating shaft 19 passing through the interior of the sealing cover 3 is fixedly connected to a cam 20, and the side of the cam 20 away from the rotating shaft 19 is fixedly connected to a connecting shaft 21, a tensioning wheel 22 is fixedly connected to the surface of the connecting shaft 21, the cam 20 and the tensioning wheel 22 are eccentrically arranged, the tensioning wheel 22 is located on the inner side of the chain 7, a thread 23 is provided on the end of the rotating shaft 19 located outside the sealing cover 3, and a nut 24 is threadedly connected to the surface of the rotating shaft 19.

[0044] Through the arrangement of the above structure, the cam 20 rotates and cooperates with the tensioning wheel 22 to adjust the tension to prevent the chain 7 from loosening during use, which may cause the chain 7 to jump teeth and slip, thereby improving the stability of the structure during use.

[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0046] When in use, after the crude lead is melted in the copper removal pot, the stirring device is started, and the copper removal agent and the slag refinement agent are added. After the refined slag is formed on the lead liquid surface, the wheel bucket type slag removal machine is adjusted to a suitable slag removal height through the hydraulic cylinder 18, and the reduction motor 5 drives the sprocket 6 to rotate, and the sprocket 6 drives the chain 7 to transmit. In the sealing cover 3, the slag removal plate 43 drives the filter slag bucket 44 to rotate along the outer circle of the slag loading bucket 46, so that the filter slag bucket 44 can remove slag and filter. The rotation of the slag removal plate 43 makes the filter slag bucket 44 move in the range. The slag is removed by rotating and reciprocating in the enclosure, and the wheel bucket slag remover realizes continuous slag removal. The specific gravity of the lead liquid is much greater than that of the floating slag and has strong fluidity. The lead is initially filtered through the round hole 45 on the filter slag bucket 44. When the filter slag bucket 44 is at a certain angle, the flap 47 is turned over to further filter the lead liquid and release the waste slag into the slag loading bucket 46, so as to realize the low-pollution slag removal operation on the pot surface. While the above work is being carried out, the original dust removal fan on the other side is started to absorb the smoke generated by the lead pot, forming a working cycle;

[0047] During the slag scooping process, the filter slag bucket 44 starts the electric push rod 12 to drive the movable plate 13 to reciprocate, and the movable plate 13 drives the gears 10 on both sides to rotate back and forth through the teeth 14, and the gears 10 drive the rotating shaft 9 to rotate back and forth, and the rotating shaft 9 drives the knocking ball 16 to move back and forth through the support rod 15, and continuously knocks the outer side of the filter slag bucket 44, so as to shake out the residue in the round hole 45, and prevent the filter slag bucket 44 from being blocked and affecting the slag scooping efficiency;

[0048] When the reduction motor 5 drives the chain 7 for transmission, the nut 24 is loosened and then the cam 20 is driven to rotate. The cam 20 drives the tensioning wheel 22 to perform eccentric adjustment, so that the cam 20 cooperates with the tensioning wheel 22 to tighten to prevent the chain 7 from loosening during use, which may cause the chain 7 to jump teeth and slip.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
