Abstract
The invention belongs to the technical field of particles screening and grinding, and in particular relates to a device for screening, grinding and adding particles of a calcium oxide chemical in flotation. The device is characterized by comprising two slewing supporting devices which are arranged at the top of a middle chemical storing case, a rotary screen drum which is arranged between the two slewing supporting devices and is located in a chemical feeding port of the middle chemical storing case, and a chemical feeding pipe and a reflux pipe which are respectively communicated and connected with the middle of the rotary screen drum. The device is simple in structure and light in weight, and is unnecessary to additionally arrange a driving device, thereby reducing the energy consumption. According to the device, the solid particles in a calcium oxide chemical solution are effectively ground and screened, so that the solid particles are finer and the effective utilization rate is improved, and therefore, the concentration and the granularity of preparing the calcium oxide chemical solution are guaranteed.
Description
Technical field
The invention belongs to particle screening grinding technique field, especially relate to the particle screen mill adding set of calcium oxide medicament in a kind of flotation operation.
Background technology
Calcium oxide is widely used in many iron ore dressings factory as the activator in the flotation process.The production scene generally all is the calcium oxide liquid medicine that will prepare, and from Scatula explosive box in the middle of pump pumps and sends into, delivers to dosing tank from middle explosive box again and enters the flotation operation.To the concentration of calcium oxide liquid medicine preparation, chemical feeding quantity has strict regulation and restriction in flotation process.Owing in the process for preparation of calcium oxide liquid medicine, inevitably producing solid particle, solid particle not only causes the loss of active ingredient in the calcium oxide liquid medicine, thereby affect flotation effect, and solid particle very easily stops up again parts of appliance such as adding pipe and valve, can not guarantee the normal interpolation of medicament, cause the flotation iron concentrate grade significantly, fast-descending.
Summary of the invention
The purpose of this invention is to provide a kind of can effectively the screening and lapping device the solid particle in the calcium oxide liquid medicine.
The objective of the invention is to realize by following technical proposals:
The particle screen mill adding set of calcium oxide medicament in the flotation operation of the present invention, it is characterized in that comprising two rotary supporting devices at explosive box top in the middle of being located at, be located between these two rotary supporting devices, and the rotation screen drum of explosive box drug delivery port in the middle of being positioned at, rotate therewith respectively the screen drum middle part and connect delivery tube and the return duct that connects
Described rotary supporting device comprises the bearing assembly that is fixed on described middle explosive box top, be located at the pivoting support sleeve in this bearing assembly, one end of this pivoting support sleeve is fixedly connected with the middle part of described rotation screen drum, described delivery tube and return duct are located at respectively in described two pivoting support sleeves
Described rotation screen drum is provided with screen cloth in the circumferential direction of the circle, and the middle part inwall of described rotation screen drum is connected with one group of blade, is provided with one group of abrasive media in the described rotation screen drum.
Described abrasive media is steel ball.
The mesh diameter of described screen cloth is 1-1.5mm.
Advantage of the present invention:
The present invention is simple in structure, and is lightweight, the blade when entering the rotation screen drum by the calcium oxide liquid medicine in the impulsive force driven rotary screen drum of itself, drive the rotation of rotation screen drum, thereby grind and sieving technology, do not need to add in addition drive unit, more environmental protection and attenuating energy consumption.The present invention can effectively grind screening to the solid particle in the calcium oxide liquid medicine, and solid particle is more careful, and effective rate of utilization improves, thereby guarantees concentration and the granularity of the preparation of calcium oxide liquid medicine.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A view of Fig. 1 of the present invention.
The specific embodiment
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the particle screen mill adding set of calcium oxide medicament in a kind of flotation operation, it is characterized in that comprising two rotary supporting devices at explosive box top in the middle of being located at, be located between these two rotary supporting devices, and the rotation screen drum 1 of explosive box drug delivery port 6 in the middle of being positioned at, rotate therewith respectively screen drum 1 middle part and connect delivery tube 5 and the return duct 9 that connects
Described rotary supporting device comprises the bearing assembly 3 that is fixed on described middle explosive box top, be located at the pivoting support sleeve 4 in this bearing assembly 3, one end of this pivoting support sleeve 4 is fixedly connected with the middle part of described rotation screen drum 1, described delivery tube 5 and return duct 9 are located at respectively in described two pivoting support sleeves 4
Described rotation screen drum 1 is provided with screen cloth 10 in the circumferential direction of the circle, and the middle part inwall of described rotation screen drum is connected with one group of blade 2, is provided with one group of abrasive media 7 in the described rotation screen drum 1.
Described abrasive media 7 is steel ball.
The mesh diameter of described screen cloth 10 is 1-1.5mm.
When the medicament that carries out flotation operation feeds operation, with the calcium oxide liquid medicine 8 for preparing, pump through pump from Scatula first, and explosive box in the middle of sending into by this particle screen mill adding set.Calcium oxide liquid medicine 8 is in feed pipe 5 enters into rotation screen drum 1, reflux solution is also in return duct 9 enters into rotation screen drum 1 simultaneously, owing to itself having certain pressure when the calcium oxide liquid medicine pumps from Scatula, when impacting on the blade 2 in the rotation screen drum 1, blade 2 can do 360 by driven rotary screen drum 1
0Revolution, abrasive media 7 steel balls in the rotation screen drum 1 also do 360 with rotation screen drum 1
0Revolution, and under Action of Gravity Field, glide along rotation screen drum 1 inwall, at this moment, the calcium oxide particle particle diameter is less than the particle of screen cloth 10 mesh diameters, explosive box in the middle of automatically flowing into, and the larger calcium oxide particle of particle diameter will be subject to the grinding of steel ball and percussion and fragmentation, when being crushed to particle diameter less than screen cloth 10 mesh diameter, explosive box in the middle of flowing into is finished the screen mill process, reaches flotation to the requirement of calcium oxide granularity.
The present invention is simple in structure, and is lightweight, the blade 2 when entering rotation screen drum 1 by calcium oxide liquid medicine 8 in the impulsive force driven rotary screen drum 1 of itself, drive 1 rotation of rotation screen drum, thereby grind and sieving technology, do not need to add in addition drive unit, more environmental protection and attenuating energy consumption.The present invention can effectively grind screening to the solid particle in the calcium oxide liquid medicine 8, and solid particle is more careful, and effective rate of utilization improves, thereby guarantees concentration and the granularity of 8 preparations of calcium oxide liquid medicine.
