Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heavy calcium powder processing, and particularly relates to a quantitative feeding equipment for heavy calcium powder processing. BACKGROUND

[0002] Heavy calcium carbonate, referred to as heavy calcium, is white powder processed from high-quality limestone by a lime grinding machine. Heavy calcium has the characteristics of high whiteness, good purity, soft color, stable chemical composition, etc. Heavy calcium is usually used as a filler and is widely used in the daily chemical industry such as artificial floor tiles, rubber, plastics, papermaking, paint, paint, ink, cable, building materials, food, medicine, textile, feed, toothpaste, etc. as a filler to increase the volume of products and reduce production costs.

[0003] The existing heavy calcium powder processing feeding equipment usually uses simple mechanical conveying (such as belt conveying or high-difference gravity feeding), which lacks dynamic adjustment capability, resulting in large flow fluctuation when the raw material enters the grinding machine. For example, when the stock bin supplies the mill through a high difference, uneven feeding is easily caused by changes in raw material bulk density or equipment vibration, which further affects the grinding efficiency and product fineness consistency. In addition, the extensive control of manual intervention cannot meet the requirements of heavy calcium powder for raw material supply precision, resulting in increased load of subsequent classification screening, and even multiple rework, which needs to be improved. SUMMARY

[0004] The purpose of the present application is to provide a quantitative feeding equipment for heavy calcium powder processing, which can solve the above problems.

[0005] The purpose of the present application is to provide a quantitative feeding equipment for heavy calcium powder processing, which includes:

[0006] A support base;

[0007] A conveying mechanism arranged on the support base for conveying heavy calcium powder;

[0008] A weighing mechanism connected with the conveying mechanism for receiving and weighing the heavy calcium powder conveyed by the feeding mechanism;

[0009] Wherein, the conveying structure is installed obliquely, and the weighing mechanism is located below the conveying mechanism.

[0010] The conveying mechanism of the application adopts an inclined installation mode, can convey the heavy calcium powder from bottom to top, can effectively utilize the vertical space, reduce the equipment floor area, and ensure the continuous supply of heavy calcium powder. The weighing mechanism is directly located below the conveying mechanism, can seamlessly receive the material output by the conveying mechanism, and realizes real-time monitoring and control through weighing, avoiding the cumulative metering error caused by multiple material transfer links in traditional equipment. The conveying mechanism and the weighing mechanism are integrated through the support base, forming a compact integrated layout, reducing the equipment floor area, and facilitating on-site installation and maintenance.

[0011] The application realizes the continuous process from conveying, weighing to quantitative feeding through the physical position cooperation of the conveying mechanism and the weighing mechanism, and solves the material supply fluctuation problem caused by the dispersed structure of traditional equipment.

[0012] Further, the conveying mechanism comprises:

[0013] The feeding pipe is provided with a feeding port at one end and a discharging port at the other end;

[0014] The rotating rod is rotatably arranged in the feeding pipe, and the helical blade is fixedly connected to the rotating rod;

[0015] The driver is arranged on the feeding pipe and connected with the rotating rod, and is used for driving the rotating rod to rotate;

[0016] In the application, the heavy calcium powder is input from the feeding port, the driver drives the helical blade to rotate through rotation, and the heavy calcium powder is conveyed to the discharging port.

[0017] Through the feeding port and the discharging port of the feeding pipe and the rotary motion of the helical blade with the rotating rod, a one-way material pushing path is formed, the stable conveying of the heavy calcium powder from the feeding end to the discharging end is ensured, and the random fluctuation of the flow in the traditional free-fall feeding is avoided. At the same time, the integrated design of the feeding pipe, the rotating rod and the driver makes the overall volume of the conveying mechanism small, which can flexibly adapt to the space limitation of the production line, reduce the material transfer links, and reduce the risk of blockage. In addition, in the application, the helical blade and the inner wall of the feeding pipe are gap-fitted, which can adapt to the conveying requirements of heavy calcium powder with different particle sizes or slight caking, and prevent the agglomeration of powder caused by jamming or excessive extrusion.

[0018] Further, the weighing mechanism comprises:

[0019] The storage bin is provided with an inlet at the top, and the inlet is communicated with the storage port;

[0022] The outlet of the storage bin is provided with a valve, the valve is connected with a weighing sensor, and the weighing sensor is connected with the buffer bin. When the weight of the heavy calcium powder in the buffer bin is lower than a set threshold, the weighing sensor controls the valve to open, and drives the storage bin to supplement the buffer bin.

[0023] The storage bin and the buffer bin are vertically connected to form a stepped feeding path. The buffer bin serves as an intermediate temporary storage unit, which can buffer the impact of concentrated feeding of the storage bin on downstream equipment, avoid the direct impact of the spiral weighing feeder on the instantaneous large flow of the storage bin, and ensure the continuity of subsequent quantitative feeding. The outlet valve of the storage bin is linked with the weighing sensor. By monitoring the weight of the material in the buffer bin in real time, the storage bin only supplements the buffer bin when the storage amount of the buffer bin is insufficient, so as to maintain the dynamic balance of the material amount in the buffer bin and prevent weighing errors or feeding interruptions caused by excessive accumulation.

[0024] Meanwhile, the spiral weighing feeder is directly connected to the outlet of the buffer bin. Through the built-in metering function, which can be a weighing module or a flow sensor, the spiral weighing feeder can realize the accurate and continuous output of the heavy calcium powder from the buffer bin to the downstream equipment. The spiral weighing feeder is an existing device, and its specific structure is not described here.

[0025] In addition, the buffer bin is vertically located below the storage bin, which can realize natural feeding of the storage bin to the buffer bin by gravity, reducing additional power consumption. The spiral weighing feeder is located at the bottom of the buffer bin, which can effectively avoid the blockage of the discharge port caused by the deliquescence or electrostatic adsorption of the powder.

[0026] Further, the support base is provided with a support frame for supporting the buffer bin, the storage bin and the spiral weighing feeder.

[0027] In the present application, the support frame is composed of a plurality of support rods which are connected by bolts, nuts and other detachable fasteners, so as to facilitate on-site rapid assembly or adjustment of the frame size, and to adapt to the installation requirements of storage bins, buffer bins and spiral weighing feeders of different capacities. The support rods are rigidly connected to form an integral frame, which shares the load of the storage bin, the buffer bin and the spiral weighing feeder, and reduces the risk of frame deformation caused by vibration or change of material weight during equipment operation.

[0028] Further, the drive is installed at one end of the feeding pipe close to the discharge port, and is connected with the rotating rod through a belt and a belt pulley.

[0029] The driver is located at the discharge end of the material conveying pipe, and power is transmitted to the rotating rod through a belt wheel and a belt, the belt transmission has a flexible connection characteristic, can reduce the instantaneous impact force through belt slip when the spiral blade encounters large block material blockage, avoids the risk of driver burnout caused by rigid transmission, and the driver is a motor.

[0030] Further, the support base is provided with a support rod connected with the material conveying pipe and an electric telescopic rod, and the support rod and the electric telescopic rod are both hinged with the material conveying pipe.

[0031] The support rod and the electric telescopic rod are both hinged with the material conveying pipe, the inclination angle of the material conveying pipe relative to the support base is changed by adjusting the telescopic length of the electric telescopic rod, the conveying path height or inclination angle requirement of different production lines is adapted, and the electric telescopic rod is connected with an external power supply. Meanwhile, the support rod provides a rigid fixed point, the electric telescopic rod serves as an adjustable support point, and both of them cooperate to ensure that the material conveying pipe remains stable after angle adjustment, and avoid conveying vibration or deviation caused by pure flexible suspension.

[0032] The beneficial effects of the present application are:

[0033] 1. The present application realizes a continuous process from conveying, weighing to quantitative feeding by the physical position cooperation of the conveying mechanism and the weighing mechanism, and solves the material supply fluctuation problem caused by the dispersed structure of traditional equipment.

[0034] 2. The outlet valve of the storage bin is linked with the weighing sensor, the material weight in the buffer bin is monitored in real time, the storage bin only replenishes when the buffer bin inventory is insufficient, the material amount in the buffer bin is dynamically balanced, and weighing error or material supply interruption caused by excessive accumulation is prevented.

[0035] 3. The screw weighing feeder is located at the bottom of the buffer bin, and the material is forced to push by the rotation of the spiral blade, which can effectively avoid the blockage of the discharge port caused by the deliquescence or electrostatic adsorption of the powder.
