Abstract
The utility model relates to a hydraulic double-roll crushing mill comprising a power accumulator, a rack, a base, an oil cylinder, a movable roll, a fixed roll, a hydraulic station, a motor, a cardan joint, a coupler and a speed reducer. The hydraulic double-roll crushing mill is characterized in that the movable roll and the fixed roll are installed in the rack which is installed on the base, the movable roll is connected with the oil cylinder and is propped by the pressure of the power accumulator, a main shaft of the movable roll is connected with the cardan joint and the coupler, the other ends of the cardan joint and the coupler are connected with the speed reducer and the motor, and the fixed roll is connected with the speed reducer and the motor by the coupler. The hydraulic double-roll crushing mill realizes constant speed, constant pressure and constant particle size, is strong in overload capacity, low in running cost and suitable for crushing middle-size or larger materials, and quick-wear parts are long in service life.
Description
Technical field
The utility model relates to a kind of hydraulic pressure double-roll crusher, comprising: accumulator, frame, base, oil cylinder, action roller, fixed roll, Hydraulic Station, motor, universal joint, shaft coupling, reductor.
Background technology
In the fragmentation processing of the processing in small, broken bits of the medium above material of metallurgy, building materials, chemical field and ball mill leading portion material in small, broken bits, need the material of 10-50mm granularity be crushed to below the 10mm, to reach raising output, the purpose that cuts down the consumption of energy.
The existing double-roll crusher that uses is to control moving back and forth of action roller with spring, is the control granularity, and it is last that the gap between two rollers will be limited in certain distance, and limit with limited block.Under the effect of spring, action roller props up limited block, is keeping certain clearance between two rollers simultaneously.In shattering process, more moment expects or has and can not fall by broken hard thing sometimes, forces the spring compression.Through behind the pair roller, spring yet resets at broken material.The compression that does not in use stop along with spring and resetting, spring can be gradually inefficacy, cause broken material to increase gradually, do not reach the purpose of fragmentation in small, broken bits, just need the dismounting frame to change spring, relatively waste time and energy.
Existing a kind of double-roll crusher like patent of invention 200910017951.9, comprises drive unit, driving shaft, driven shaft, transmission mechanism, roller, charging aperture, discharging opening, support; Transmission mechanism is made up of active tire and driven tire; Driving shaft one end links to each other with drive unit; The other end links to each other with the active tire, and driven shaft links to each other with driven tire, and active tire and driven tire are closely cooperated each other; Tightly be with roller on driving shaft, the driven shaft respectively, be fixed with tooth in upright arrangement on the roller; When two rollers do relative motion, the material that gets in the disintegrating machine is pushed, material particles is diminished, and make the smooth access arrangement body of material particles; Also has a kind of gear type double-roll crusher; Like practicality novel 97229112.1; Comprise mainframe, hopper, body, bearing block, bearing, running roller, baffle plate, belt pulley, motor, look nut, pressure regulation rod, pressure spring; Be fixedly connected gear on the axis of two running rollers respectively, two gears are meshing with each other.All adopt with spring and control moving back and forth of action roller, under the effect of spring, action roller props up limited block.In shattering process, more moment expects or has and can not fall by broken hard thing sometimes, forces the spring compression, after broken material passes through pair roller, and spring reset.The compression that does not in use stop along with spring and resetting, spring can be gradually inefficacy, cause broken material to increase gradually, do not reach the purpose of fragmentation in small, broken bits, just need the dismounting frame to change spring, relatively waste time and energy.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art; A kind of double-roll crusher with hydraulic means is provided; The oil cylinder that props up action roller is presetting certain pressure, and it is last to make two rollers be in the distance of setting all the time, and two roll gap pressures are constant; Clearance constant, make broken raw meal particle size also constant.
For realizing above-mentioned purpose; The utility model comprises: accumulator, frame, base, oil cylinder, action roller, fixed roll, Hydraulic Station, motor, universal joint, shaft coupling, reductor is characterized in that: action roller, fixed roll are installed in the frame, and frame is installed on the base; Action roller is connected with oil cylinder; The action roller main shaft is connected with gimbal coupling, and the other end of gimbal coupling is connected with motor with reductor, and fixed roll is connected with motor with reductor through shaft coupling.
The advantage of the utility model
The utility model has overcome prior art moving back and forth with spring control action roller; The compression that does not in use stop along with spring and resetting, the spring fade causes broken material to increase gradually; Do not reach crushing effect in small, broken bits, often need the dismounting frame to change the deficiency of spring.The utility model adopts hydraulic means, and its advantage is: pressure is powerful and balanced, and buffer capacity is good, and self-protection is good, has the characteristics of constant speed, constant voltage, constant particle size, and overload capacity is strong, consumable accessory long service life, the characteristics that operating cost is low.
Description of drawings
Accompanying drawing is the utility model structural representation:
Fig. 1 is a front view;
Fig. 2 is a vertical view, among the figure: 1, accumulator, 2, frame, 3, base, 4, oil cylinder, 5, action roller, 6, fixed roll, 7, Hydraulic Station, 8, motor, 9, universal joint, 10, shaft coupling, 11, reductor.
The specific embodiment
As shown in the figure: action roller 5, fixed roll 6 are installed in the frame 2; Frame 2 is installed on the base 3; Action roller 5 is connected with oil cylinder 4; Action roller 5 main shafts are connected with universal joint 9, shaft coupling 10, and the other end of universal joint 9, shaft coupling 10 is connected with motor 8 with reductor 11, and fixed roll 6 is connected with motor 8 with reductor 11 through shaft coupling 10.Two motors, two reductors drive fixed roll 6 respectively and action roller 5 rotates in opposite directions.Action roller 5 main shafts one end is connecting universal joint 9, shaft coupling 10, reductor 11 and motor 8, and fixed roll 6 main shafts one end is connecting shaft coupling 10, reductor 11 and motor 8.The rotation of pair roller is the motor and speed reducer of same model, guarantees its rotary speed constant speed.When get between the pair roller can not be broken hard thing or moment during many material, in time reset automatically after the certain angle of universal joint 9, shaft coupling 10 skews.The oil cylinder 4 that props up action roller 5 is presetting certain pressure, and it is last to make two rollers be in the distance of setting all the time, constant to keep-up pressure, and has also guaranteed clearance constant, thus guarantee broken raw meal particle size constant.
