Description
TECHNICAL FIELD
[0001] The utility model belongs to vertical stirring grinding ore dressing technology field especially, it relates to a CSM1120 vertical mill long -life type ore dressing device. BACKGROUND
[0002] CSM1120 vertical stirring grinding mill (hereinafter referred to as vertical mill) is generally used as the third grinding and dressing machine after the strong magnetic of refractory ore and the flotation.
[0003] Its original ore dressing device is composed of cylinder discharge port (1000X520mm), buffer tank (400X1000X520mm), φ325 ore dressing pipe, and is suspended and fixed on 8.5m base platform.
[0004] The original ore dressing device cannot be long-lived to meet the use requirement, and has the following problems, 1, the design ore dressing box space is narrow, and the clear maintenance work cannot be smoothly completed, 2, the buffer tank is 400mm long, and the ore pulp path changes 90 degrees after buffer tank, and flows out from the lower part of ore dressing management. If the buffer tank is less than 400mm long, the liquid flow impact force is large, causes the ore pulp to directly impact the buffer tank face and bottom tank wall, causes the tank wall to be seriously worn, and no wear-resistant layer is arranged, the service life is short, cannot meet the long-life production requirement of equipment, 3, the ore dressing pipe is connected to the bottom of buffer tank, and can only pass through from the upper part of pump pit and the lower part of maintenance crane due to the limitation of building space and self-flowing slope requirement, causes the pump maintenance operation under the following to generate a dangerous source, and the hoisting accident probability increases to 80%, 4, the ore dressing of buffer tank lower part cannot completely play the role of buffer and separation of sundries. SUMMARY
[0005] The utility model discloses a CSM1120 vertical mill long -life type ore dressing device, and solves the problems of existing ore dressing device.
[0006] The utility model discloses a CSM1120 vertical mill long -life type ore dressing device, and solves the problems of existing ore dressing device.
[0007] The utility model discloses a CSM1120 vertical mill long -life type ore dressing device, and solves the problems of existing ore dressing device.
[0008] The buffer tank bottom is equipped with support structure support.
[0009] The ore dressing pipe is located in the middle upper part of the side of the buffer tank.
[0010] The utility model discloses a CSM1120 vertical mill long -life type ore dressing device, and solves the problems of existing ore dressing device.
[0011] The CSM1120 vertical mill long-life ore discharging device has the advantages of simple structure, easy manufacturing, convenient maintenance, low labor intensity, prolonged service life of the ore discharging device, prolonged service life from 20 days to more than 2 years, reduced maintenance operation time and workload, saved maintenance cost of not less than 700,000 yuan in the life cycle, eliminated a dangerous source, created social benefits, and reduced safety responsibility loss of not less than 500,000 yuan. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 It is a structural schematic view of the utility model.
[0013] Figure 2 It is an A view of the utility model. Figure 1 DETAILED DESCRIPTION
[0014] The specific implementation of the utility model will be further described below in combination with the drawings.
[0015] As shown in the drawings, Figure 1 , 2 The CSM1120 vertical mill long-life ore discharging device of the utility model has the characteristics that it comprises a cylinder discharge port 1, a buffer tank 2 connected with the cylinder discharge port 1, a magnetic lining plate 3 arranged on the side wall and the bottom of the buffer tank 2, and an ore discharging pipe 4 arranged on the side of the buffer tank 2, wherein the ore discharging pipe 4 passes through between the crane cross beam and the ceiling.
[0016] The bottom of the buffer tank 2 is provided with a support structure support 5.
[0017] The ore discharging pipe 4 is located in the middle upper part of the side of the buffer tank 2.
[0018] The CSM1120 vertical mill long-life ore discharging device of the utility model is composed of a cylinder discharge port 1 (1000X520mm), a buffer tank 2 (1216X1000X2000mm), a magnetic lining plate 3, a support structure support 5, and a φ325 ore discharging pipe 4. The specific technical scheme is as follows: 1. The structure of the large-size buffer tank 2 is redesigned, and the length, width and height are changed to 1216X1000X2000mm, which facilitates post cleaning and maintenance. 2. The magnetic lining plate 3 is laid on the side wall and the bottom of the buffer tank 2 box, which can adsorb magnetic materials and form ore grinding ore, thereby doubling the service life of the components. 3. Because the weight of the buffer tank 2 is increased, a support structure support 5 is made and installed. 4. The connecting port of the ore discharging pipe 4 is changed from the bottom to the side of the buffer tank 2, so that the buffer tank 2 can pass through between the crane cross beam and the ceiling, which does not affect the walking and hoisting operation of the gourd hoist, eliminates the dangerous source, and ensures the need of ore pulp self-flow. 5. The buffer tank 2 is changed to the middle upper part of the side for ore discharging, which plays the role of buffering and separating sundries.
[0019] This utility model relates to a long-life discharge device for the CSM1120 vertical mill. It features a simple structure, easy manufacturing, convenient inspection and maintenance, low labor intensity, and extends the service life of the discharge device from 20 days to over 2 years. It reduces maintenance time and workload, saving at least 700,000 yuan in maintenance costs over its lifespan, eliminating a potential hazard, creating social benefits, and reducing safety liability losses by at least 500,000 yuan.
