Abstract
The utility model discloses a protective device of a vertical ball grinder, which comprises a water pressure gauge and a control device, wherein the water pressure gauge is mounted on a water delivery pipe and used for detecting water pressure of a circulating grinding fluid in the water delivery pipe; the water pressure gauge is connected with the control device and sends the detected water pressure to the control device; and a material disc motor driving a material disc to rotate and a grinding disc motor driving a lower grinding disc to rotate are connected with the control device, so that the control device can control the material disc motor and the grinding disc motor. The protective device of the vertical ball grinder is simple in structure; the water pressure gauge detects the water pressure of the water delivery pipe delivering the circulating grinding fluid to a feed port and sends water pressure information to the control device, and when the control device discovers that the water pressure is lower than a set threshold, the control device controls the material disc motor and the grinding disc motor to stop working, so that the vertical ball grinder is shut down; abrasion of the grinding discs and steel balls is avoided; the service lives of the grinding discsare ensured; economic loss caused by damage of the grinding discs is avoided as far as possible; the production quality of the steel balls is ensured; the overhaul times and the overhaul consumed time of the ball grinder are reduced; the production continuity is ensured; manpower and material resources are saved; and the production efficiency of the steel balls is ensured.
Description
Technical field
The utility model is related to a kind of protection device, specifically, is a kind of vertical ball crusher protection device.
Background technology
Steel ball is machined using abrading-ball, secondary a upper millstone and lower millstone is mainly used to be ground steel ball, need to be cooled down and lubricated again in the overall process of grinding, flowed into so having circulation grinding fluid in process of lapping between two mills, circulating grinding fluid has cooling, lubrication, cutting and the effect of antirust, also promising that steel ball is sent between mill to the effect for providing power.Current ball crusher is all without protection device, when occurring insufficient circulation grinding fluid or cutout, mill and steel ball will not completely be lubricated, cooling, steel ball number between feeding mill can also be reduced, pressure between the mill that each steel ball undertakes can also increase, easily cause the abrasion of mill and steel ball, mill after abrasion cannot be used, worn out steel ball also becomes substandard products, and because mill is mainly resin wheel, price is higher, the abrasion of mill will directly bring larger economic loss, change and maintenance mill is time-consuming also laborious, directly contribute steel ball stopping production, make the big drop of production efficiency.
Utility model content
The utility model does not have protection device for current ball crusher; when the conveying capacity for occurring circulation grinding fluid is reduced or stopped; easily cause the abrasion of mill and steel ball; increase defect rate; cause economic loss; maintenance is wasted time and energy, the problems such as substantially reducing steel ball production efficiency, devises a kind of vertical ball crusher protection device
Vertical ball crusher protection device of the present utility model, vertical ball crusher includes charging tray, upper millstone and lower millstone, upper millstone and lower millstone are oppositely arranged, charging tray is by rotating transporting steel balls, upper millstone is provided with opening, opening is divided into charging aperture and discharging opening by gap bridge guide plate, vertical ball crusher also includes conveying the flow pipe for circulating grinding fluid to charging aperture, described protection device includes water pressure gauge and control device, water pressure gauge is arranged on flow pipe, hydraulic pressure for detecting flow pipe interior circulation grinding fluid, water pressure gauge is connected with control device, the hydraulic pressure detected is sent to control device, the charging tray motor of driving charging tray rotation and the millstone motor of driving lower millstone rotation are also all connected with control device, control device is set to can control charging tray motor and millstone motor.
The beneficial effects of the utility model are：Vertical ball crusher protection device is simple in construction, the hydraulic pressure for the flow pipe that circulation grinding fluid is conveyed to charging aperture is detected by water pressure gauge, and hydraulic pressure information is sent to control device, when control device finds hydraulic pressure less than the threshold value set, charging tray motor and millstone motor will be controlled to be stopped, vertical ball crusher is set to stop, prevent the abrasion of mill and steel ball, it ensure that the service life of mill, also the economic loss caused by mill is damaged is avoided as far as possible, it also ensure that the quality of production of steel ball, reduce the number of times of abrading-ball machine overhauling and overhaul every time the time of consumption, it ensure that the continuity of production, also save manpower and materials, it ensure that the production efficiency of steel ball.
Brief description of the drawings
Accompanying drawing 1 is the structure chart of this vertical ball crusher protection device.
Embodiment
Vertical ball crusher protection device of the present utility model; as shown in Figure 1; vertical ball crusher includes charging tray 1, upper millstone 2 and lower millstone; upper millstone 2 and lower millstone are oppositely arranged; charging tray 1 is by rotating transporting steel balls; upper millstone 2 is provided with opening, and 3 points by gap bridge guide plate of opening is charging aperture 4 and discharging opening 5, and vertical ball crusher also includes conveying the flow pipe 6 for circulating grinding fluid to charging aperture 4.
Vertical ball crusher protection device includes water pressure gauge 7 and control device 8; water pressure gauge 7 is arranged on flow pipe 6; hydraulic pressure for detecting the interior circulation grinding fluid of flow pipe 6; water pressure gauge 7 is connected with control device 8; the hydraulic pressure detected is sent to control device 8; the charging tray motor and the millstone motor of driving lower millstone rotation that driving charging tray 1 rotates also all are connected with control device 8, control device 8 is can control charging tray motor and millstone motor.
The hydraulic pressure of the interior circulation grinding fluid of flow pipe 6 detected is sent to the threshold value that a setting is set in control device 8, control device 8 by water pressure gauge 7.When hydraulic pressure in flow pipe 6 reduces or is zero, flow-reduction or the cutout of the interior circulation grinding fluid of flow pipe 6 are meant that.The detection of water pressure gauge 7 is real-time, when the hydraulic pressure for the circulation grinding fluid that water pressure gauge 7 is detected is less than the threshold value set, control device 8 just controls charging tray motor and millstone motor to be stopped, and charging tray is stopped the feeding into mill, stop the rotation of mill simultaneously, it is to avoid shot scratches mill.
