Description

Technical Field

[0001] The invention belongs to the technical field of heavy calcium carbonate production and processing, and specifically relates to a raw material conveying device and a production process for heavy calcium carbonate production. Background Art

[0002] As an important inorganic chemical product, heavy calcium carbonate is widely used in many fields such as plastics, rubber, papermaking, coatings, inks, etc. With the growing demand for heavy calcium carbonate in various industries, its production scale is also expanding, which puts forward higher requirements for each link in the production process, especially the raw material transportation link.

[0003] The raw material transportation link directly affects the overall space size of the workshop.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] When a traditional vertical conveyor is in use, since the conveying pipe is set on one side, feeding can only be carried out on the other side, resulting in too great overall limitations and poor adaptability. However, the present application can enable the conveying pipe to effectively transport materials at all angles in the conveying trough through the rotation of the transfer pipe. This method changes the limitation of the traditional vertical conveyor that it can only transport on one side, and such a design can make material feeding more convenient and quick, can realize feeding at all angles, and has better adaptability.

[0019] The design of the first adjusting block, the second adjusting block, the first clamping rod, the second clamping rod, the clamping slot and the hydraulic rod is fixed by the clamping engagement of the second clamping rod and the clamping slot. At this time, the second adjusting block is connected and fixed to the corresponding conveying pipe and the base pipe, and the first adjusting block is connected and fixed to the transfer pipe. In addition, the transfer pipe is rotatably connected to the conveying pipe and the base pipe. Therefore, it is only necessary to extend the hydraulic rod to push the first adjusting block in one direction, thereby realizing the rotation of the transfer pipe to a set angle. After the transfer pipe rotates, the first clamping rod is controlled to engage with the clamping slot, and the second clamping rod is released from the clamping slot. At this time, the second adjusting block can be automatically approached to the first adjusting block by the contraction of the hydraulic rod, so that the first adjusting block and the second adjusting block restore the initial distance. Through such continuous reciprocating cycles, the conveying pipe can be rotated to a set angle each time, thereby realizing the rotation of the conveying pipe.

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be another element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A raw material conveying device for the production of heavy calcium carbonate includes a conveying base 1, on which an inverted conical conveying trough is provided, a vertical and rotatable transfer tube 22 is provided in the middle of the conveying trough, a conveying pipe 2 that is connected and rotatably connected is provided at the upper end of the transfer tube 22, a discharge pipe 21 is provided on one side of the upper end of the conveying pipe 2, an arc-shaped feed trough 230 is provided on one side of the transfer tube 22, a rotatable conveying shaft 24 is provided in the middle of the transfer tube 22 and the conveying pipe 2, and a spiral auger blade 25 for conveying raw material particles is provided on the conveying shaft 24.

[0035] When a traditional vertical conveyor is in use, since the conveying pipe 2 is set on one side, feeding can only be carried out on the other side, resulting in too great overall limitations and poor adaptability. By rotating the transfer tube 22, the conveying pipe 2 can effectively convey materials at all angles in the conveying trough. This method changes the limitation of the traditional vertical conveyor that it can only convey on one side, and such a design can make material feeding more convenient and quick, can realize feeding at all angles, and has better adaptability.

[0036] In this example, see Figure 3 , Figure 4 , Figure 5 A fixedly connected base tube 23 is provided at the bottom of the center of the conveying trough, and the base tube 23 is rotatably connected to the transfer tube 22. Adjustment ring grooves 226 are provided at both the upper and lower ends of the transfer tube 22. The adjustment ring grooves 226 are provided with a fixedly connected first adjustment block 28. A retractable first clamping rod 281 is provided on the first adjustment block 28. A slidingly connected second adjustment block 29 is also provided in the adjustment ring groove 226. A retractable second clamping rod 291 is provided on the second adjustment block 29. A plurality of evenly distributed clamping grooves 20 for engaging the first clamping rod 281 and the second clamping rod 291 are provided on one side of the conveying pipe 2 and the base tube 23. A connected and retractable hydraulic rod 282 is provided between the first adjustment block 28 and the second adjustment block 29.

[0037] The design of the first adjusting block 28, the second adjusting block 29, the first clamping rod 281, the second clamping rod 291, the clamping slot 20 and the hydraulic rod 282 is that the second clamping rod 291 is engaged and fixed with the clamping slot 20. At this time, the second adjusting block 29 is connected and fixed with the corresponding conveying pipe 2 and the base pipe 23, and the first adjusting block 28 is connected and fixed with the transfer pipe 22. In addition, the transfer pipe 22 is rotatably connected with the conveying pipe 2 and the base pipe 23. Therefore, the first adjusting block 28 can be pushed toward one side only by extending the hydraulic rod 282. The transfer tube 22 is pushed in each direction, thereby realizing the rotation of the set angle. After the transfer tube 22 rotates, the first clamping rod 281 is controlled to engage with the clamping slot 20, and the second clamping rod 291 is released from the clamping slot 20. At this time, the second adjusting block 29 can be automatically moved toward the first adjusting block 28 by contracting the hydraulic rod 282, so that the first adjusting block 28 and the second adjusting block 29 restore the initial distance. Through such continuous reciprocating cycles, the conveying tube 2 can be rotated by a set angle each time, thereby realizing the rotation of the conveying tube 2.

[0038] In this example, see Figure 5 The first clamping rod 281 and the second clamping rod 291 are in the shape of a lock tongue, and the inclined arc surfaces at the ends of the first clamping rod 281 and the second clamping rod 291 are in the same direction. The first adjustment block 28 and the second adjustment block 29 are both provided with adjustment grooves, and the adjustment grooves are both provided with return springs 283 for driving the first clamping rod 281 and the second clamping rod 291 to automatically pop out.

[0039] The design of the reset spring 283 can realize the automatic engagement of the first clamping rod 281 and the second clamping rod 291 with the clamping slot 20, and the first clamping rod 281 and the second clamping rod 291 are in the shape of lock tongues, and the inclined arc surfaces at the ends of the first clamping rod 281 and the second clamping rod 291 are designed in the same direction, which realizes the automatic extension and retraction of the first clamping rod 281 and the second clamping rod 291, and ensures the rotational stability of the conveying tube 2.

[0040] In this example, see Figure 4 , Figure 5 , Figure 6The transfer tube 22 is provided with a hydraulic groove 222, and a hydraulic plate 224 is provided in the hydraulic groove 222 for sliding and sealing connection. A guide groove 221 is provided on one side of the hydraulic groove 222. The extending ends of the guide groove 221 are respectively connected to the hydraulic rods 282 on the two first adjustment blocks 28. A first spring 223 is provided in the hydraulic groove 222 for driving the hydraulic plate 224 to restore the initial position. A linkage rod 225 is provided in the adjusting ring groove 226. One end of the linkage rod 225 slides The conveying shaft 24 passes through the hydraulic groove 222 and is fixedly connected to the hydraulic plate 224 in a dynamic and sealing manner. The bottom of the conveying base 1 passes through a conveying base 1. The bottom of the conveying base 1 is provided with a plurality of driving grooves 231 which are evenly distributed in an annular shape and are connected to the corresponding adjusting ring grooves 226. The driving grooves 231 are each provided with a driving rod 232 which is slidably connected and used for pressing by the linkage rod 225. The end of the driving rod 232 is hemispherical. The conveying shaft 24 is provided with a pressing plate 26 which is fixedly connected and used for pressing by the driving rod 232.

[0041] The design of the driving rod 232, the pressing plate 26, the hydraulic plate 224, the first spring 223 and the guide groove 221 can drive the pressing plate 26 to rotate during the rotation of the conveying shaft 24. The rotation of the pressing plate 26, combined with the hemispherical design of the driving rod 232, can press the passing driving rods 232 in turn. When moving to the linkage rod 225, the pressing plate 26 presses the linkage rod 225 through the driving rod 232, so that the hydraulic plate 224 moves. Due to the hydraulic transmission, the hydraulic rod 282 is contracted. When the pressing plate 26 is separated from the linkage rod 225, the elasticity of the first spring 223 can drive the hydraulic plate 224 to restore its initial position. In this way, the automatic extension of the hydraulic rod 282 can be achieved through hydraulic transmission. Such a design can achieve the automatic extension and retraction of the hydraulic rod 282 without adding additional power equipment, thereby reducing the overall cost. The design of synchronous extension and retraction of the upper and lower hydraulic rods 282 can ensure the stability of the rotation of the transfer tube 22. At the same time, the extension and retraction amount of the hydraulic rod 282 can be controlled by controlling the diameter of the hydraulic rod 282 and the volume change of the hydraulic groove 222.

[0042] In this embodiment, a second spring for driving the driving rod 232 to automatically pop out downward is provided in the driving slot 231. The addition of the third spring can effectively prevent the driving rod 232 from being unable to move downward only by gravity due to friction, so that the driving rod 232 can automatically return to its initial position after the external force is lost.

[0043] In this example, see Figure 1 , Figure 2 A sealing cover 3 is provided on the conveying base 1 , and the sealing cover 3 is fixedly connected to the conveying pipe 2 . A plurality of feed ports 31 are provided on the outer side of the sealing cover 3 .

[0044] The addition of the sealing cover 3 can effectively prevent excessive dust from appearing after the raw material particles enter the conveying trough, and effectively prevent dust.

[0045] In this example, see Figure 2 , Figure 3 , Figure 6 The conveying pipe 2 is provided with a connected spray ring pipe 44, and a plurality of evenly distributed spray pipes 42 are provided outside the spray ring pipe 44. The spray pipe 42 is provided with a spray hole 43. The bottom of the conveying base 1 is provided with a liquid storage tank 4, and the liquid storage tank 4 is provided with a spray liquid. The liquid storage tank 4 is provided with a conveying mechanism for conveying the spray liquid to the spray pipe 42. The design of the spray pipe 42 can realize the cleaning of the raw material particles by spraying, and can also effectively reduce the overall dust amount.

[0046] In this example, see Figure 2 , Figure 3 , Figure 6 The liquid storage tank 4 is arranged directly below the conveying shaft 24, and a fixedly connected infusion box 41 is provided in the liquid storage tank 4, and a slidable and sealed conveying plate 46 is provided in the infusion box 41. The bottom of the conveying shaft 24 moves through the infusion box 41 and the middle of the conveying plate 46. A reciprocating thread 27 is provided on the conveying shaft 24 located in the infusion box 41, and the conveying shaft 24 and the conveying plate 46 are connected by the reciprocating thread 27. A one-way liquid inlet 47 is provided on one side of the infusion box 41, and a one-way liquid outlet 48 is provided on the other side of the infusion box 41. A connected guide pipe 45 is provided at the one-way liquid outlet 48, and the extending end of the guide pipe 45 is connected to the spray ring pipe 44.

[0047] The design of the conveying shaft 24, the reciprocating thread 27, the conveying plate 46, the one-way liquid outlet 48 and the one-way liquid inlet 47 can utilize the characteristics of the reciprocating thread 27 while the conveying shaft 24 is rotating to achieve the periodic reciprocating motion of the conveying plate 46, and then cooperate with the one-way liquid outlet 48 and the one-way liquid inlet 47, so that the infusion box 41 can deliver the spraying fluid in the liquid storage tank 4 to the spray pipe 42, thereby achieving automatic spraying of the spray liquid.

[0048] In this embodiment, a plurality of fixedly connected conveying brackets are provided at the bottom of the conveying base 1 , and a driving motor 11 is provided at the bottom of the conveying base 1 . A synchronous chain connected to the driving motor 11 and the conveying shaft 24 is provided.

[0049] In this embodiment, a through-type reflux hole is provided at the bottom of the conveying trough, the base tube 23 is fixedly connected to the reflux hole, and a filter net is provided at the bottom of the base tube 23 to prevent the raw material from falling, and the reflux hole is located directly above the liquid storage tank 4.

[0050] The design of the reflux hole and the filter screen enables the spray liquid in the conveying tank to clean the raw material particles, and then filter the impurities through the filter screen to recover the impurities to the liquid storage tank 4, while the raw material particles are transported and lifted by the spiral auger blades 25. In order to improve the drying efficiency of the raw material particles, the spiral auger blades 25 can be set to be porous. Such a design can make the surface moisture of the raw material particles fall automatically due to gravity during the rising process, and dry faster.

[0051] In this embodiment, the upper end of the conveying pipe 2 can be set to be porous, and fan blades can be set on the conveying shaft 24 at the upper end of the conveying pipe 2. At the same time, the upper half of the conveying pipe 2 is also set to be porous. In this way, the conveying shaft 24 can drive the fan blades to rotate while driving the original particles to rise, thereby generating airflow, and utilizing the flow of the airflow to make the original particles dry faster.

[0052] When using this application:

[0053] The raw material particles are fed into the conveying trough through the feed port 31, and the driving motor 11 is started to drive the conveying shaft 24 to rotate. The rotation of the conveying shaft 24 drives the spiral auger blades 25 to rotate, so that the raw material particles pass through the feed trough 230 and enter the transfer tube 22, and then are lifted vertically upward by the spiral auger blades 25, directly moving the raw material particles to the discharge pipe 21, and automatically falling through the discharge pipe 21, so that the raw material particles are transported to the next link;

[0054] When the conveying shaft 24 rotates, the characteristics of the reciprocating thread 27 can drive the conveying plate 46 to periodically reciprocate up and down, and then cooperate with the one-way liquid outlet 48 and the one-way liquid inlet 47, so that the infusion box 41 can send the spraying liquid in the liquid storage tank 4 to the spray pipe 42, thereby realizing the automatic spraying of the spraying liquid; in this way, after the raw material particles enter the conveying tank, they can be automatically cleaned by the spraying liquid sprayed from the spray pipe 42, and dust can also be effectively reduced. After the cleaned liquid enters the transfer tube 22, it automatically enters the liquid storage tank 4 through the filter screen at the bottom, thereby realizing the recycling of the spraying liquid;

[0055] As the conveying shaft 24 rotates, the pressing plate 26 can be driven to rotate synchronously. The rotation of the pressing plate 26 allows it to periodically pass through the corresponding driving rod 232 in sequence. With the hemispherical design of the driving rod 232, it can press the driving rod 232 that passes through in sequence. When the pressing plate 26 moves to the linkage rod 225, the pressing plate 26 presses the linkage rod 225 through the driving rod 232, so that the hydraulic plate 224 moves. Due to the hydraulic transmission, the hydraulic rod 282 is retracted. At this time, since the first clamping rod 281 and the second clamping rod 291 are both engaged with the clamping groove 20, and the first adjustment block 28 is fixedly connected to the adjustment ring groove 226, and then with the locking tongue-shaped inclined arc surface at the end of the second clamping rod 291, the contraction of the hydraulic rod 282 can pull the second adjustment block 29 toward the first adjustment block 28 to the set position;

[0056] When the pressing plate 26 is separated from the linkage rod 225, the elasticity of the first spring 223 can drive the hydraulic plate 224 to return to the initial position, so that the hydraulic rod 282 can be automatically extended through the hydraulic transmission. At this time, since the back of the second clamping rod 291 can be engaged with the clamping groove 20 for support, the second adjustment block 29 is connected and fixed with the corresponding base tube 23 and the conveying pipe 2, so that the second adjustment block 29 remains fixed. Therefore, the extension of the hydraulic rod 282 can push the first clamping rod 281 on the first adjustment block 28 to move a set distance along the direction of the inclined arc surface. At this time, the automatic rotation of the transfer tube 22 to the set angle has been completed.

[0057] Therefore, each time the pressing plate 26 moves to the linkage rod 225, the transfer tube 22 can be rotated in one direction to a set angle, so that the feed trough 230 can convey the raw material particles at any angle in the conveying trough. This can not only realize the vertical conveying of the raw material particles, but also realize the feeding of the raw material particles at any angle, which is more adaptable.
