Description

Technical Field

[0001] The present invention belongs to the field of powder material metering and feeding, and in particular relates to a multi-ring controlled powder material steady flow metering and feeding device. Background Art

[0002] Accurately metering and quantitative feeding of powder materials in storage silos has always been a difficult problem for manufacturers. The reason is that, on the one hand, the powder materials after grinding have a certain degree of adhesion under normal conditions, and the adhesion becomes stronger as the moisture content increases. In addition, the storage silo has a large capacity, which results in long storage times and a large actual pressure time constant, which makes the powder material flow performance worse. On the other hand, dry powder materials or those accompanied by airflow have extremely strong fluidity, which is manifested as the material tends to overflow. The greater the air content, the stronger the fluidity. Therefore, the flow state of the powder material will directly affect the smooth progress of the quantitative feeding process. At present, traditional metering and feeding equipment will have problems such as breakage, fluctuation, rushing, and inaccurate metering due to the flow state of the powder material, and the application effect is poor. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-ring controlled powder material steady flow metering and feeding device in order to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A multi-ring controlled powder material steady flow metering and feeding device comprises a feeder and a steady flow bin arranged at the upper end of the feeder, wherein an inclined hopper for feeding the powder material is provided on one side of the steady flow bin;

[0006] A weighing device, comprising a weighing scale mounted on the feeder legs and a rotor scale non-rigidly connected to the feeder outlet, for measuring and dosing powder materials; and

A plurality of cams are provided on the activation rod. When the driving component drives the activation rod to rotate to activate the powder material accumulated in the oblique bucket, the cam on the activation rod rotates together and pushes the toggle component and the dispersion cover to move up and down to achieve full dispersion of the powder material.

[0008] As a further optimization scheme of the present invention, the telescopic support member includes a movable frame, a fixed seat, an insertion rod and a spring member. The fixed seat is fixedly arranged at the upper end of the flow stabilization bin, the movable frame is connected to the insertion rod, the insertion rod is movably connected to the fixed seat, and one end of the insertion rod extends into the fixed seat and is connected to the spring member.

[0009] As a further optimization scheme of the present invention, the drive assembly includes a chassis, a bevel gear set and a drive motor. The chassis is arranged on the outer wall of the stabilizing chamber. One end of the activation rod extends into the chassis and is connected to the driven end of the bevel gear set. The driving end of the bevel gear set is connected to the drive shaft of the drive motor.

[0010] As a further optimization scheme of the present invention, the toggle assembly includes a frame connected to the telescopic support member, a guide wheel and a transmission roller are provided inside the frame, a transmission gear is provided on the transmission roller, a steel rope is connected to the transmission roller, the steel rope extends along the upper end of the guide wheel and passes through the frame and is connected to the inner wall of the dispersion cover, and the inner wall of the stabilizing chamber is provided with a rack that meshes with the transmission gear.

[0014] The beneficial effects of the present invention are:

[0015] The present invention adopts the first-ring adjustment of the steady flow bin + activation and dispersion component, the second-ring fine-tuning link of the feeder + rotor scale, and the expected control of the rotor scale itself as the third-ring adjustment.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-4 As shown, a multi-ring controlled powder material steady flow metering and feeding device comprises a feeder 1, and also comprises a steady flow bin 2 provided at the upper end of the feeder 1, and an inclined hopper 3 for feeding the powder material is provided on one side of the steady flow bin 2;

[0026] The weighing device includes a weighing scale 14 provided on the legs of the feeder 1 and a rotor scale 4 non-rigidly connected to the discharge port of the feeder 1, which is used for measuring and quantitative feeding of powder materials; and

[0027] An activation and dispersion component is provided in the stabilizing bin 2, and the activation and dispersion component includes an activation rod 7 with a driving component 8 connected to one end and a curved shape at the other end extending to the oblique bucket 3, a telescopic support 9 provided at the top of the stabilizing bin 2, a toggle component 10 connected to the lower end of the telescopic support 9, and a dispersion cover 6 hinged to the lower end of the toggle component 10. A plurality of cams 11 are provided on the activation rod 7. When the driving component 8 drives the activation rod 7 to rotate to activate the powder material accumulated in the oblique bucket 3, the cam 11 on the activation rod 7 rotates together and pushes the toggle component 10 and the dispersion cover 6 to move up and down to achieve full dispersion of the powder material.

[0028] The present invention adopts the first ring adjustment of the stabilizing bin 2 + activation and dispersion component, the second ring fine adjustment link of the feeder 1 + rotor scale 4, and the expected control of the rotor scale 4 itself as the third ring. The multi-ring control enables the powder material to be fully activated and dispersed and fed into the stabilizing bin 2 for buffering by the stabilizing bin 2. Different from the method of directly unloading from the storage bin, the bin pressure in the storage bin, the stability of unloading or short-term interruption of the material will not affect the feeding of the feeder 1. Then, through the measurement and adjustment of the rotor scale 4, accurate measurement and feeding of the powder material can be achieved.

[0029] Furthermore, the telescopic support member 9 includes a movable frame 901, a fixed seat 902, an insertion rod 903 and a spring member 904. The fixed seat 902 is fixedly arranged at the upper end of the stabilizing chamber 2, the movable frame 901 is connected to the insertion rod 903, the insertion rod 903 is movably plugged into the fixed seat 902, and one end of the insertion rod 903 extending into the fixed seat 902 is connected to the spring member 904. The cam 11 on the activation rod 7 pushes the toggle assembly 10 and the dispersion cover 6 to move up and down to provide support through the telescopic support member 9. When in use, the toggle assembly 10 and the dispersion cover 6 move downward, pulling the insertion rod 903 and the fixed seat 902 to produce relative displacement, so that the insertion rod 903 pulls the spring member 904 to stretch, and the toggle assembly 10 and the dispersion cover 6 are reset under the elastic force of the spring member 904.

[0030] Furthermore, the driving assembly 8 includes a chassis 801, a bevel gear set 802 and a driving motor 803. The chassis 801 is arranged on the outer wall of the stabilizing chamber 2. One end of the activation rod 7 extends into the chassis 801 and is connected to the driven end of the bevel gear set 802. The active end of the bevel gear set 802 is connected to the driving shaft of the driving motor 803. When in use, the driving motor 803 drives the bevel gear set 802 to drive the activation rod 7 to rotate at a uniform speed. The activation rod 7 extends into the curved end of the oblique bucket 3 to stir the powder material in the oblique bucket 3, thereby realizing the activation and dispersion of the material in the oblique bucket 3, avoiding the problem of blockage and breakage of the powder material in the oblique bucket 3.

[0031] Furthermore, the toggle assembly 10 includes a frame 1001 connected to the telescopic support 9, a guide wheel 1002 and a transmission roller 1004 are provided inside the frame 1001, a transmission gear 1005 is provided on the transmission roller 1004, and a steel rope 1003 is connected to the transmission roller 1004, and the steel rope 1003 extends along the upper end of the guide wheel 1002 and passes through the frame 1001 and is connected to the inner wall of the dispersion cover 6. The inner wall of the stabilizing bin 2 is provided with a rack 1006 that meshes with the transmission gear 1005. When in use, the driving assembly 8 drives the activation rod 7 to rotate to perform powder material accumulation in the inclined bucket 3. At the same time as activation, the cam 11 on the activation rod 7 rotates together and pushes the toggle assembly 10 and the dispersion cover 6 to move up and down. The transmission gear 1005 on the transmission roller 1004 at one end of the frame 1001 engages with the rack 1006 for transmission, and the transmission roller 1004 rotates and reels the steel rope 1003. The steel rope 1003 pulls the dispersion cover 6 to rotate relative to the frame 1001. Then, as the dispersion cover 6 moves up and resets, the transmission roller 1004 releases the steel rope 1003 in the opposite direction, and the dispersion cover 6 also resets accordingly. As the dispersion cover 6 moves up and down, it swings left and right, fully breaking up the powder material so that it is evenly dispersed and then falls into the feeder 1.

[0032] like Figure 5 As shown, baffles 12 are symmetrically provided at both ends of the dispersion cover 6. The symmetrically designed baffles 12 can catch the powder material to a greater extent and play a role in guiding the material to fall.

[0033] A dust collecting device 5 is provided at the top of the steady flow bin 2 to collect the gas in the steady flow bin 2 in time without interfering with the weighing of the metering scale 14. The discharge port of the rotor scale 4 is connected to the lower conveying equipment.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 、 6 As shown, a main control device 13 is also included, and the operation control end of the drive component 8, the motor control end of the feeder 1, the operation control end of the metering scale 14 and the motor control end of the rotor scale 4 are electrically connected to the control port of the main control device 13 respectively.

[0036] The main control device 13 uses a touch screen as the human-machine interface and an all-Chinese operating interface. Human-machine dialogue and fault finding are simple and easy, and maintenance, repair, calibration and other tasks are convenient and simple. In addition, the main control device 13 adopts three basic operating modes, namely on-site manual control, electric control cabinet manual / automatic control and central control room automatic control, which fully meet actual operating needs.

[0037] The material level control and quantitative feeding operation are specifically as follows: the main control device 13 sets the total weight of the feeder 1, the steady flow bin 2 and the material in the bin when the material is at the highest / lowest material level in the steady flow bin 2; the metering scale 14 weighs the weight of the feeder 1, the steady flow bin 2 and the material in the bin and forms a load feedback signal of the steady flow bin 2 to the main control device 14; the main control device 13 sends a motor control signal of the feeder 1 to control the speed of the feeder 1 to increase / decelerate, speed up / decelerate the feeding process, so that the material level in the steady flow bin 2 drops / rises; at the same time, the main control device 13 sends a control signal of the drive component 8 to control the speed of the drive motor 803 of the drive component 8 to increase / decelerate, speed up / decelerate The activation and dispersion speed of the activation rod 7 and the dispersion cover 6 causes the material level in the steady flow bin 2 to drop / rise. According to the above-mentioned operation process, the material level in the steady flow bin 2 can be controlled to be within the set range. In addition, the specific value of quantitative feeding is set by the main control device 13, and the feeder 1 feeds the powder material into the rotor scale 4, and the rotor scale 4 transports the powder material to the lower-level conveying equipment. At the same time, the rotor scale 4 weighs the powder material inside, and the rotor scale 4 forms a rotor scale 4 weighing signal to the main control device 13. However, when the specific value of quantitative feeding is reached, the main control device 14 sends a rotor scale 4 motor control signal to control the rotor scale 4 motor to stop, and the quantitative feeding ends.

[0038] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
