Description

Technical Field

[0001] The present invention relates to the technical field of calcium carbonate processing, and particularly to a discharging device for heavy calcium carbonate processing. Background Art

[0002] The preparation of calcium carbonate powder refers to the process of converting natural calcium carbonate minerals or synthetic raw materials into calcium carbonate powder with certain particle size, purity, and performance requirements through a series of physical or chemical methods. This process usually includes steps such as raw material crushing, grinding, classification, purification, and necessary surface treatment to meet the requirements of particle size, whiteness, purity, and surface properties of calcium carbonate powder for different industrial applications.

[0003] Calcium carbonate powder needs to be safely and efficiently transferred from storage devices (such as silos, bins, or packaging bags) to transportation tools or subsequent processing equipment, ensuring the smoothness, accuracy of discharging, and effective control of dust, thereby improving production efficiency and reducing environmental pollution.

[0004] Currently, the discharging process usually uses a vibration structure, relying on the self-weight of the powder for discharging, and also generates negative pressure through the continuous flow of air to suck out the powder to complete discharging. However, after long-term use of vibration discharging, it will accelerate the aging and detachment of parts. Airflow discharging requires sealing at the discharge port. To avoid a large amount of powder spraying out and floating around, seriously polluting the environment, the operation of this collection process is rather troublesome.

[0005] Moreover, most of today's discharging mechanisms are installed inside the tank body. If there are multiple devices, it will greatly increase the cost. During the grinding process of calcium carbonate powder, there will inevitably be a large amount of powder near the tank body, and the amount of powder at the outer edge of the tank body will be greatly reduced. When the staff discharges the material, they need to wait near the tank body to close the discharge port. Therefore, when the staff is in an environment with a large amount of powder for a long time, it will affect their physical health. Summary of the Invention

[0014] Preferably, one end of the feeding pipeline extends to the upper end face of the discharging main body, the discharging pipeline extends to the side end face of the discharging main body, and the stacking pipeline is perpendicular to the feeding pipeline and the discharging pipeline respectively. One-way flow valves are provided at the connection parts of the feeding pipeline and the discharging pipeline with the stacking pipeline.

[0015] Preferably, the one-way flow valve includes a one-way plate and a one-way valve body.

[0017] Compared with the prior art, the present invention provides a discharging device for heavy calcium carbonate processing, which has the following beneficial effects: 1. For the discharging device for heavy calcium carbonate processing, the discharging equipment can be moved freely through the wheels, greatly increasing the discharging distance of calcium carbonate powder. It can effectively prevent workers from inhaling more powder due to being too close to the grinding equipment, which affects their physical health. Moreover, through the movable discharging main body, it can be conveniently docked with different equipment to complete the discharging of various equipment, greatly increasing its applicability and reducing its cost.

For the discharging device for heavy calcium carbonate processing, through the setting of the breathing airbag and the reciprocating component, when the top of the breathing airbag moves up and down, it can simulate the breathing process. When moving upward, through the change of air pressure, the discharging effect can be achieved. Through such a breathing effect, after the powder is pushed out, the air flow will also end spraying. At this time, the situation of powder flying caused by the air flow spraying can be greatly weakened.

[0019] 3. For the discharging device for heavy calcium carbonate processing, by adjusting the position of the adjusting nut ring, the power of the air flow can be increased. At this time, the powder can be pushed to a farther position, thereby improving the gas power generated by the breathing airbag and avoiding insufficient power, which may cause the powder to be blocked in the pipeline and unable to be discharged.

Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-6 shown, it includes a discharging main body 10. A channel, a discharging assembly 30 and an adjusting assembly 40 are arranged in the discharging main body 10. An adjusting component is also arranged on the discharging assembly 30. A suction port 101 is arranged on the upper end surface of the discharging main body 10. The suction port 101 is located on the feeding pipeline 11. The suction port 101 is provided as a hose. Wheels 102 are also installed at the bottom of the discharging main body 10. Among them, the interface of the suction port 101 can be rotated at will, so that it can be flexibly installed on the discharging port of the storage equipment or the grinding equipment. Then, discharging is carried out through the discharging main body 10. Then, the discharging equipment can be moved at will through the wheels 102, greatly increasing the discharging distance of the calcium carbonate powder. The calcium carbonate is ground into powder by the grinding equipment and then falls to the bottom of the equipment. Its outlet can be connected to the suction port 101. The discharging port is extended through the discharging main body 10. Since a large amount of powder floats nearby during the operation of the grinding equipment, it can effectively prevent the staff from being too close to the grinding equipment and inhaling more powder, which affects their physical health. Moreover, through the movable discharging main body 10, it can be conveniently docked with different equipment to complete the discharging of various equipment, greatly increasing its applicability.

[0024] The channel is provided with a feeding pipeline 11, a stacking pipeline 12 and a discharging pipeline 13. The feeding pipeline 11 and the discharging pipeline 13 are both communicated with the stacking pipeline 12. One end of the feeding pipeline 11 extends to the upper end surface of the discharging main body 10 and is communicated with the suction port 101. The feeding pipeline 11 is arranged in an L shape, and its horizontal part is communicated with the stacking pipeline 12. The discharging pipeline 13 extends to the side end surface of the discharging main body 10. The stacking pipeline 12 is perpendicular to the feeding pipeline 11 and the discharging pipeline 13 respectively. Wherein, one-way flow valves 20 are arranged at the joints of the feeding pipeline 11 and the discharging pipeline 13 with the stacking pipeline 12. The one-way flow valves 20 are made of light materials. An air chamber 14 is also opened in the discharging main body 10. The air chamber 14 is arranged above the stacking pipeline 12 and is communicated with the stacking pipeline 12. A breathing airbag 301 and a breathing stretching rod 302 are arranged in the air chamber 14. The bottom of the air chamber 14 is arranged in a frustum shape, and the small round opening of the frustum shape is communicated with the stacking pipeline 12, which can increase the air flow pressure. At the same time, when the powder floats into the breathing airbag 301, it will re-stack in the stacking pipeline 12 under the action of its own weight. The one-way flow valve 20 includes a one-way plate 201 and a one-way valve body 202. The one-way valve body 202 is fixed on the inner wall of the channel, and the one-way plate 201 is hinged on the one-way valve body 202. The one-way plate 201 at the feeding pipeline 11 is located on the side close to the stacking pipeline 12, and the one-way plate 201 at the discharging pipeline 13 is located on the side far from the stacking pipeline 12. A discharge port 50 is also movably connected in the discharging pipeline 13. A part of the discharge port 50 is located outside. By stretching the discharge port 50, the distance between the discharge port and the grinding equipment can be further increased, improving the safety of the staff.

[0025] The discharging assembly 30 includes a breathing airbag 301, a breathing stretching rod 302 and a reciprocating assembly. The breathing airbag 301 and the breathing stretching rod 302 are rotatably connected, and the breathing stretching rod 302 can drive the breathing stretching rod 302 to move synchronously. One end of the breathing airbag 301 is fixed on the inner wall of the air chamber 14, and the breathing airbag 301 is arranged in a corrugated shape, and the corrugated part is in a stepped shape. A threaded hole 3021 is formed inside the breathing stretching rod 302, and a nut ring 3022 is threadedly connected in the threaded hole 3021. A square hole is arranged in the middle of the nut ring 3022. The sliding rod 303 is arranged in a square shape, and the sliding rod 303 is in close fit with the square hole of the nut ring 3022. The breathing stretching rod 302 is movably connected with the reciprocating assembly. The reciprocating assembly includes a sliding rod 303, a hydraulic rod 304 and a hydraulic cylinder 305. A hydraulic oil pipeline is arranged on the hydraulic cylinder 3005 for connecting an external oil pump to provide power. The hydraulic rod 304 slides in the hydraulic cylinder 305. The hydraulic cylinder 305 is fixedly installed in the discharging main body 10. The hydraulic rod 304 and the sliding rod 303 are controlled by the hydraulic cylinder 305 to move up and down in a cyclic reciprocating manner. The sliding rod 303 is fixed on one side of the hydraulic rod 304. A bottom plate 3031 is further fixed at the bottom of the sliding rod 303. The bottom plate 3031 is installed between the nut ring 3022 and the bottom of the hole of the breathing stretching rod 302.

[0026] Through the arrangement of the breathing airbag 301 and the reciprocating assembly, when the top of the breathing airbag 301 moves up and down, it can simulate the breathing process. When moving upward, due to the change of air pressure, the ground calcium carbonate powder can be inhaled into the pipeline and then enter the stacking pipeline 12, and is stacked in the vertical stacking pipeline 12. When the breathing airbag 301 moves downward, the powder stacked in the stacking pipeline 12 can be pushed out through the airflow from the discharging pipeline 13, so as to achieve the discharging effect.

[0027] Through such a breathing effect, after the powder is pushed out, the airflow also ends spraying. At this time, the situation of powder flying caused by the airflow spraying can be greatly weakened, and there is a slight floating situation. After the breathing airbag 301 sprays air and enters the inhalation stage, a sedimentation time can be given to the floating powder, further reducing the powder floating phenomenon, thereby greatly reducing powder pollution.

[0028] A number of long teeth are provided on the outer peripheral side of the breathing stretching rod 302. The adjusting assembly 40 includes an adjusting rack 401 and an adjusting screw 402. The adjusting rack 401 slides within the discharging main body 10, and one end face thereof is provided with teeth that mesh with the outer peripheral side of the breathing stretching rod 302. The adjusting screw 402 is threadedly connected to the adjusting rack 401. One end of the adjusting screw 402 extends to the outside, and an adjusting knob 403 is fixed to the outside portion thereof. By rotating the adjusting knob 403, the adjusting rack 401 can be driven to slide by the adjusting screw 402. Under the meshing of the teeth, the breathing stretching rod 302 is driven to rotate. At this time, the breathing stretching rod 302 is in a rotating state, but the nut ring 3022 and the sliding rod 303 are in a square fit and cannot rotate. Moreover, the nut ring 3022 is threadedly connected to the inside of the breathing stretching rod 302. Therefore, when the breathing stretching rod 302 rotates, the nut ring 3022 can be driven to slide on the sliding rod 303.

[0029] As Figure 7 shown, on the left side, when the nut ring 3022 is at the top of the threaded hole and the distance from the bottom plate 3031 is the farthest, the movable distance of the breathing stretching rod 302 is h. On the right side, when the nut ring 3022 is at the bottom of the threaded hole and abuts against the bottom plate 3031, the movable distance of the breathing stretching rod 302 is H, where H is greater than h.

[0030] The distance that the hydraulic cylinder 305 drives the hydraulic rod 304 and the sliding rod 303 to move up and down reciprocally remains unchanged. When the nut ring 3022 moves to abut against the bottom plate 3031, at this time, the movement of the sliding rod 303 can directly drive the breathing stretching rod 302 to move through the nut ring 3022. Therefore, the distance that the breathing airbag 301 is pulled at this time is the maximum distance, that is, the breathing airbag 301 is fully stretched, and the powder it can suck is the most. When the breathing airbag 301 moves downward, since it is in the maximum expansion state, the air flow generated by exhalation is the most. As the air flow increases, its thrust will also increase, that is, the power of the air flow increases. At this time, the powder can be pushed to a farther position. By adjusting the position of the nut ring 3022, the power generated by the breathing airbag 301 can be increased to avoid insufficient power, resulting in the powder being blocked in the pipeline and unable to be discharged. Especially when the powder conveying distance is increased after pulling out the discharge port 50, greater power is required. Moreover, when the discharge port 50 is not pulled out, the pushing force of the breathing airbag 301 is increased. At this time, the gas force is relatively large. After the powder is pushed out, a relatively large amount of the air flow will also be ejected. At this time, the excess air flow will cause more powder to be blown up by the air flow and make the powder float around, resulting in waste and pollution. Therefore, at this time, it is necessary to reduce the exhalation force of the breathing airbag 301 to reduce pollution.

[0031] Working principle: When in use, push the discharging main body 10 to the powder tank body for grinding calcium carbonate, then connect the suction port 101 to the discharging port of the tank body. After starting the hydraulic cylinder 305, powder discharging can be carried out. At this time, when the hydraulic cylinder 305 starts, it can drive the sliding rod 303 and the hydraulic rod 304 to move up and down reciprocally. Then, through the abutment of the nut ring 3022 and the bottom plate 3031, the breathing stretching rod 302 can be driven to pull the breathing airbag 301 to move reciprocally, and the breathing airbag 301 can perform a breathing-like operation. When the breathing stretching rod 302 pulls the breathing airbag 301 upward, the breathing airbag 301 performs an air suction operation, sucking the gas in the stacking pipeline 12. At this time, due to the restriction of the one-way flow valve 20 at the discharging pipeline 13, the discharging pipeline 13 is closed, and the one-way flow valve 20 at the feeding pipeline 11 is opened, so that the powder in the powder tank body can be sucked from the suction port 101 and inhaled into the stacking pipeline 12. Then, the breathing stretching rod 302 drives the breathing airbag 301 to move downward, which can drive the breathing airbag 301 to perform an air exhalation operation. At this time, gas is blown into the stacking pipeline 12, causing the gas in the stacking pipeline 12 to expand. At this time, the one-way flow valve 20 at the feeding pipeline 11 is restricted, closing the channel of the feeding pipeline 11, and the one-way flow valve 20 at the discharging pipeline 13 is opened. The gas can then push the powder into the discharging pipeline 13 and be pushed out through the discharging port 50 to complete the discharging process. The above process is repeated for subsequent discharging.

[0032] When it is necessary to increase the thrust of the breathing airbag 301, only the amount of air inhalation and exhalation of the breathing airbag 301 needs to be increased. At this time, rotate the adjustment knob 403, which can drive the adjustment rack 401 to move through the adjustment screw 402, thereby driving the breathing stretching rod 302 to rotate. The rotation of the breathing stretching rod 302 drives the nut ring 3022 to slide downward on the sliding rod 303 through the thread, increasing the moving distance of the breathing stretching rod 302, that is, the moving distance of the breathing airbag 301, namely the expansion size of the breathing airbag 301, so as to increase the amount of air inhalation and exhalation of the breathing airbag 301, thereby increasing the thrust and suction of the breathing airbag 301, enabling more powder to be inhaled and discharged farther.

[0033] In summary, for the discharging device used for processing heavy calcium carbonate, the wheel 102 enables the discharging equipment to move freely, greatly increasing the discharging distance of calcium carbonate powder. This can effectively prevent workers from inhaling excessive powder due to being too close to the grinding equipment, which affects their physical health. Moreover, the movable discharging main body 10 enables it to be conveniently docked with different equipment to complete the discharging of multiple equipment, greatly increasing its applicability. Additionally, by stretching the discharging port 50, the distance between the discharging port and the grinding equipment can be further increased, improving the safety of workers. Through the setting of the breathing airbag 301 and the reciprocating component, when the top of the breathing airbag 301 moves up and down, it can simulate the breathing process. When moving upward, through the change of air pressure, the discharging effect can be achieved. Through such a breathing effect, after the powder is pushed out, the air flow will also stop spraying. At this time, the situation of powder flying caused by the spraying of the air flow can be greatly reduced. And in the case of slight floating, after the breathing airbag 301 sprays air and enters the inhalation stage, a sedimentation time can be given to the floating powder, further reducing the powder floating phenomenon, thereby greatly reducing powder pollution. By adjusting the position of the adjusting nut ring 3022, the power of the air flow can be increased, and at this time, the powder can be pushed to a farther position, thereby improving the gas power generated by the breathing airbag 301 and avoiding powder blockage in the pipeline due to insufficient power and being unable to be discharged.
