Description

TECHNICAL FIELD

[0001] The present application relates to the field of mining separation, in particular to a concentrate ore drawing device for a mineral separator. BACKGROUND

[0002] Mineral separation is a process of selecting useful minerals from collected mineral raw materials according to the differences in physical properties, physical and chemical properties and chemical properties of various minerals, and the machine for implementing this process is called a mineral separation machine.

[0003] According to different mineral separation methods, mineral separators can be divided into two categories: physical separation and chemical separation. The most commonly used mineral separator in physical separation is a heavy medium separator. According to the different densities of mineral substances, they are separated under the action of heavy medium. The heavy medium separator usually uses liquid as medium, such as water, heavy liquid, etc. The ore will sink to the bottom when its specific gravity is greater than that of the medium, and the ore with specific gravity less than that of the medium will float on the medium. In this way, the mineral substances and impurities in the ore can be separated. However, the existing concentrate ore drawing device has the following disadvantages:

[0004] In the separation process, since the liquid is used for floating the impurities in the coal mine, the liquid will be contaminated after the separation is completed. Therefore, the liquid needs to be replaced after being used for a certain number of times. However, the amount of liquid used in mineral separation is large, which will cause waste of liquid. In addition, in the use process, the ore needs to be crushed before being floated. However, the flotation is based on the characteristics of the mineral, and the ore needs to be crushed to a certain size. If the ore does not reach the specified size, the impurities inside the ore cannot be completely removed during the flotation, which greatly reduces the quality of the produced concentrate. Moreover, the existing screening, crushing and flotation processes all need separate equipment, which requires the ore to be transferred between each set of equipment, greatly increasing the labor cost of concentrate separation.

[0005] Therefore, it is necessary to invent a concentrate ore drawing device for a mineral separator to solve the above problems. SUMMARY

[0039] A conveying belt 905 is arranged below the sieve tray 901, the conveying belt 905 is fixedly connected to the inner side of the box body 1, a discharge plate one 906 is arranged below one side of the conveying belt 905, the discharge plate one 906 is throughly connected with the inner wall of the box body 1, a recycling trailer 907 is arranged below the discharge plate one 906, the recycling trailer 907 is arranged outside the box body 1, a tray 909 is arranged below the sieve tray 901, the connecting mode of the tray 909 and the box body 1 is same as the connecting mode of the sieve tray 901, and a discharge plate two 908 is arranged below the tray 909 and is throughly connected to the inner wall of the box body 1 away from the discharge plate one 906.

[0040] Through the above structure: when the sieve tray 901 drops the screened ore above the tray 909 below, and since the sliding mode of the tray 909 is same as that of the sieve tray 901 above, the ore can be conveyed to the discharge plate two 908 on one side, and the ore not meeting the size requirement will be conveyed to the conveying belt 905 above along with the shaking of the sieve tray 901, and finally conveyed to the recycling trailer 907 above through the discharge plate one 906, so as to recycle the ore, crush and screen it again until it meets the size requirement of flotation.

[0041] In addition, since the requirements of ore flotation are different, the sizes of the required ore are also different, so different sieve tray 901 with different screen hole sizes can be replaced according to the characteristics of the floated ore

[0042] For example, Figure 1 , Figure 3 and Figure 4As shown, the power transmission structure 10 comprises: a motor 1001 mounted outside the box body 1, a belt pulley one 1002 mounted at the output end of the motor 1001, a transmission belt 1003 connected to the belt pulley one 1002, a belt pulley two 1004 connected to the transmission belt 1003, the belt pulley two 1004 is fixedly connected with the bevel gear one 7, a belt pulley three 1005 connected to the transmission belt 1003, the belt pulley three 1005 is fixedly connected with the conveying belt 905 transmission element, a belt pulley four 1006 connected to the transmission belt 1003, the belt pulley four 1006 is fixedly connected with the connecting arm 902, a belt pulley five 1007 connected to the transmission belt 1003, the belt pulley five 1007 is fixedly connected with the connecting arm 902 of the tray 909, the belt pulley one 1002, the belt pulley two 1004, the belt pulley three 1005, the belt pulley four 1006 and the belt pulley five 1007 are all arranged outside the box body 1 and are axially connected with the corresponding connecting members, and the connecting shafts all penetrate through the box body 1.

[0043] Through the above structure: when the motor 1001 starts, it will drive the belt pulley one 1002 to rotate and drive the belt pulley two 1004, the belt pulley three 1005, the belt pulley four 1006 and the belt pulley five 1007 to rotate through the transmission belt 1003 at the same time, so that the corresponding connected components work, ensuring that the upper screening structure 9 can work at the same time. By combining screening and crushing processes, the need for ore transportation between devices is avoided, and the power transmission structure 10 can drive simultaneously, eliminating the need for manual operation of separate processes, greatly improving screening efficiency and reducing labor costs. Moreover, the belt pulley one 1002 and the transmission belt 1003 inside the power transmission structure 10 are all anti-skid treated, and the rest are the same, preventing power loss during equipment operation.

[0044] As shown in Figure 1 , Figure 2 , Figure 6 and Figure 7 , the water circulation structure 11 comprises: a sorting box 1101 arranged below the discharge plate two 908, a connecting frame 1102 arranged in the sorting box 1101, a chute 1103 formed in the inner wall of the connecting frame 1102, a screw 1104 rotatably connected in the chute 1103, and a motor 1105 mounted in the chute 1103, the output end of the motor 1105 is fixedly connected with the screw 1104.

[0045] Through the above structure: when the screened ore on the discharge plate two 908 falls, it will fall into the sorting box 1101, and there is a large amount of flotation medium liquid in the sorting box 1101, and this medium can be replaced according to the specific characteristics of the ore to be floated.

[0046] As shown in Figure 2 ,Figure 6 And Figure 7 As shown in

[0047] Through the above structure: through the screw rod 1104 drive internal thread block 1106 movement, make one side fixed frame 1107 drive below connecting rod 1108 rotation, and make connecting rod 1108 below drive slide block 1109 along the slide rail 1110 slide, make connecting rod 1108 to the fixed frame 1107 flush position close.

[0048] As shown in Figure 2 、 Figure 6 And Figure 7 The connecting rod 1108 side fixedly connected with filter plate 1112, connecting rod 1108 both sides of the filter plate 1112 symmetrically installed two groups, and two groups of connecting rod 1108 are connected with fixed frame 1107 and fixed frame 1111 in the same way.

[0049] Through the above structure: when connecting rod 1108 in the moving process will drive filter plate 1112 movement, at this time due to the symmetrical setting of two groups, make two groups of filter plate 1112 hinge shape, will sorting box 1101 from the bottom start a two, will the larger suspended impurities in the liquid to the filter plate 1112 above.

[0050] As shown in Figure 2 、 Figure 6 And Figure 7 The fixed frame 1107 in away from the internal thread block 1106 side fixedly connected with limit block 1113, connecting frame 1102 in away from the chute 1103 side set up with limit slot 1114, limit slot 1114 and limit block 1113 slide connection, connecting frame 1102 and sorting box 1101 connection mode and fixed frame 1107 and connecting frame 1102 connection mode is same.

[0051] With the above structure, when the fixed frame 1107 moves, the limiting block 1113 will slide along the limiting groove 1114 to ensure the stable operation of the fixed frame 1107. In addition, by moving in the same way as the fixed frame 1107, the connecting frame 1102 can be moved upward from inside the sorting box 1101, so that the impurities above the filter plate 1112 can float to the surface of the liquid, making it easier for manual cleaning.

[0052] like Figure 1 As shown, a water outlet pipe 1115 is connected to one side of the sorting box 1101. The water outlet pipe 1115 is connected to a bidirectional water pump 1116. A water inlet pipe 1118 is connected to one side of the bidirectional water pump 1116. The water inlet pipe 1118 is connected to the sorting box 1101. A filter tank 1117 is connected to one side of the bidirectional water pump 1116. The connection method between the bidirectional water pump 1116 and the filter tank 1117 is the same as the connection method between the sorting box 1101. A sealing door 1119 is provided on the side of the sorting box 1101 away from the water outlet pipe 1115.

[0053] Through the above structure, the bidirectional water pump 1116 can transport the medium inside the sorting box 1101 to the filter tank 1117. At this time, the liquid is filtered through the filter tank 1117. The filtration method inside the filter tank 1117 can be activated carbon filtration, but is not limited to activated carbon filtration. The liquid entering the filter tank 1117 at this time is the liquid that has been filtered by the filter plate 1112. Since the liquid inside the sorting box 1101 is pumped out, the sealing door 1119 can be opened at this time to take out the selected ore inside.

[0054] The present invention discloses a concentrate discharge device for a mineral processing machine, the specific usage of which is as follows:

[0055] 1. The motor 1001 drives pulley 1002 to rotate. Pulley 1002, via conveyor belt 1003, simultaneously drives pulleys 1004, 1005, 1006, and 1007 to rotate. At this time, ore is fed into the crushing chamber 2 through feed pipe 4. Pulley 1004 drives bevel gear 8 to rotate, which in turn drives bevel gear 7 to rotate. Bevel gear 7 then drives the crushing shaft 5 to crush the ore within the crushing chamber 2. The ore is then discharged through discharge pipe 3 onto the screen 901. Simultaneously, pulley 1006 drives connecting arm 902 to rotate, causing one side of the screen 901 to rotate... The ore undergoes a downward circular motion, while the guide block 903 slides along the guide rail 904, causing the crushed ore above the screen plate 901 to fall through the screen holes onto the tray 909. At this time, ore that does not meet the size requirements cannot pass through the screen holes and will fall onto the conveyor belt 905 due to the vibration of the screen plate 901. The conveyor belt 905 operates through the pulley 1005, transporting the unqualified ore through the discharge plate 906 to the recycling trailer 907 for repeated crushing. At the same time, the tray 909, driven by the pulley 1007, vibrates in the same way as the screen plate 901, transporting the ore through the discharge plate 908 into the sorting box 1101, thus completing the crushing and screening of the ore.

[0056] 2, through the ore is transported to the sorting box 1101 inside after, at this time the sorting box 1101 inside exists liquid medium, at this time the ore enters the liquid inside, will carry out the flotation work, when the flotation is completed, through the drive connection frame 1102 moves downwards in the sorting box 1101, the connection frame 1102 is moved to the top of the ore, at this time the motor 1105 is started, the motor 1105 drives the screw rod 1104 to rotate, the screw rod 1104 drives the inner threaded block 1106 to slide along the sliding groove 1103, simultaneously the inner threaded block 1106 drives the fixed frame one 1107 to move downwards, makes the fixed frame one 1107 drive the connecting rod 1108 to rotate, the connecting rod 1108 drives the sliding block 1109 to slide along the slide rail 1110, makes the fixed frame one 1107 approach the fixed frame two 1111, simultaneously two groups of connecting rods 1108 rotate and drive two groups of opposite filter plates 1112 to close, form the hinge shape closed, all impurities in the liquid are filtered to the top of two groups of filter plates 1112, at this time the connecting frame 1102 is lifted upwards again, and the filter plate 1112 is exposed to the liquid level, so that the larger impurities can be filtered out at this time, at this time the bidirectional water pump 1116 is started, the liquid in the sorting box 1101 is pumped out and transported to the filter tank 1117, since the larger impurities have been filtered, the smaller impurities in the liquid can be completely filtered through the filter tank 1117, at this time the internal selected ore is taken out by opening the sealing door 1119, finally the bidirectional water pump 1116 retransports the filtered liquid to the sorting box 1101 through the water inlet pipe 1118, so as to complete the flotation of the ore.

[0057] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of the claims of the present application.
