DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0011] The filling pump provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0012] like Figures 1 to 21 As shown, the embodiment of the present application discloses a filling pump, which includes a feed plate 100, a distribution plate 200, a booster 300 and a drive member 400. The booster 300 is used to pressurize the material. Optionally, the booster 300 can be a hydraulic cylinder, a pneumatic cylinder, etc., and the embodiment of the present application does not make specific restrictions on this.

[0013] The feed tray 100 is provided with a feed port 110, and the distribution tray 200 is rotatably disposed in the receiving space of the feed tray 100. Optionally, the shape of the receiving space of the feed tray 100 can be adapted to the distribution tray 200, that is, the receiving space is a disc-shaped structure.

[0014] The first side 210 of the distribution plate 200 is provided with a feed bin 220 and a discharge bin 230 arranged at intervals, and the feed bin 220 is connected to the feed port 110. Optionally, the side wall of the feed bin 220 is provided with a through hole 221, and the feed bin 220 is connected to the feed port 110 through the through hole 221, and the material entering the feed port 110 enters the feed bin 220 through the through hole 221. The discharge bin 230 is provided with a discharge port 231, and the first side 210 of the distribution plate 200 is sealed with the first side wall 120 of the feed plate 100. Since there is a pressure difference between the feed bin 220 and the discharge bin 230, that is, the pressure in the discharge bin 230 is greater than the pressure in the feed bin 220, when the first side 210 of the distribution plate 200 is sealed with the first side wall 120 of the feed plate 100, the sealing performance of the feed bin 220 and the discharge bin 230 can be improved, so that the two can work separately without affecting each other. One end of the booster 300 is sealed and connected to the feed tray 100. Optionally, when the booster 300 is a pneumatic cylinder or a hydraulic cylinder, the cylinder barrel of the booster 300 is sealed and connected to the feed tray 100. The booster 300 has a accommodating cavity, and the accommodating cavity of the booster 300 is connected to the avoidance hole 121 of the first side wall 120. The avoidance hole 121 is used for allowing materials to enter and exit the booster.

[0015] The output shaft of the driving member 400 passes through the feed disk 100 and is connected to the distribution disk 200. The driving member 400 can drive the distribution disk 200 to rotate. When the feed bin 220 is connected to the avoidance hole 121, the supercharger 300 sucks the material so that the material in the feed bin 220 is sucked into the accommodating chamber, and the supercharger 300 pressurizes the material in its accommodating chamber; when the discharge bin 230 is connected to the avoidance hole 121, that is, after the supercharger 300 pressurizes the material, the supercharger 300 discharges the material so that the material in the accommodating chamber is discharged into the discharge bin 230. Optionally, the driving member 400 and the supercharger 300 can be located on the same side of the distribution disk 200, and the driving member 400 and the supercharger 300 can be arranged side by side; optionally, the driving member 400 can be a motor, and of course it can also be other types of driving devices, and the embodiment of the present application does not make specific restrictions on this.

[0016] Compared with the prior art that the hydraulic chamber of the hydraulic cylinder is connected to the outside world by the left-right switching through the S-tube valve, which causes the pressure in the downstream delivery pipeline to fluctuate, the distribution plate 200 in the embodiment of the present application is arranged in the accommodation space of the feed plate 100, and the accommodation chamber of the booster 300 is always connected to the accommodation space of the feed plate 100, so that the pressure in the feed bin 220 and the discharge bin 230 is always kept stable, thereby avoiding large fluctuations in the pressure in the delivery pipeline downstream of the discharge port 231. Therefore, this solution can solve the problem of unstable pressure in the delivery pipeline of the current filling pump.

[0017] In addition, the length of the filling pump in the above scheme is much shorter than that of the prior art, which can reduce the space occupied by the filling pump; and the distribution plate 200 rotates in the accommodating space of the feed plate 100, which can reduce the amount of sand settled at the bottom of the accommodating space. Optionally, in the circumferential direction of the distribution plate 200, the side walls of the feed bin 220 and the discharge bin 230 are provided with inclined surfaces 222, so that during the operation of the distribution plate 200, the materials in the feed bin 220 and the discharge bin 230 can flow along the inclined surfaces 222 to avoid sedimentation. Optionally, the degree of inclination of the inclined surfaces 222 can be selected according to actual needs, and the embodiment of the present application does not impose specific restrictions on this.

[0018] In an optional embodiment, the number of the supercharger 300 can be one, or the number of the supercharger 300 is at least two, the avoidance holes 121 are arranged one by one with the supercharger 300, and the feed bin 220 can be connected with the accommodating chambers of at least two superchargers 300, that is, the feed bin 220 can be connected with the accommodating chambers of at least two superchargers 300 at the same time, or the accommodating chambers of at least two superchargers 300 can be connected with the feed bin 220 at different times. The discharge bin 230 can be connected with the accommodating chambers of at least two superchargers 300, that is, the discharge bin 230 can be connected with the accommodating chambers of at least two superchargers 300 at the same time, or the accommodating chambers of at least two superchargers 300 can be connected with the discharge bin 230 at different times. This solution improves the working efficiency of the filling pump in sucking and discharging materials by setting multiple superchargers 300, so as to meet the material filling work of large displacement.

[0019] Taking the case where the number of boost components 300 is two as an example, at the same time, the accommodating chambers of the two boost components 300 can be simultaneously connected to the feed bin 220, or to the discharge bin 230, or the accommodating chamber of one boost component 300 can be connected to the feed bin 220, and the accommodating chamber of the other boost component 300 can be connected to the discharge bin 230.

[0020] Taking the case where the number of superchargers 300 is equal to three as an example, at the same time, the accommodating chamber of the first supercharger and the accommodating chamber of the second supercharger can be connected to the feed bin 220 for suction, while the accommodating chamber of the third supercharger can be connected to the discharge bin 230 for discharge; during the suction and discharge process of the supercharger 300, the distribution plate 200 rotates all the time, and after the suction and discharge work is completed, the distribution plate 200 just rotates to the discharge bin 230 of the supercharger to be connected to the accommodating chamber of the first supercharger and the accommodating chamber of the second supercharger, so as to discharge, and the discharge bin 230 is connected to the accommodating chamber of the third supercharger for suction. Of course, the three superchargers 300 can also suck or discharge at the same time.

[0021] In an optional embodiment, the outer peripheral surface of the distribution plate 200 is provided with an annular groove 240, and the annular groove 240 and the inner surface of the feed plate 100 form an annular cavity, and the feed port 110 is connected with the feed bin 220 through the annular cavity, and the material enters the annular cavity through the feed port 110, and then enters the feed bin 220 through the through hole 221 of the feed bin 220, that is, the material in the annular cavity can continuously enter the feed bin 220 to ensure the continuity of the operation of the supercharger 300; and the material first enters the annular cavity from the feed port 110 and then enters the feed bin 220, at this time, the material can be cached in the annular cavity, that is, the annular cavity has the function of buffering the material. Of course, the material can also directly enter the feed bin 220 through the feed port 110.

[0022] Optionally, the feed port 110 is located above the distribution disk 200. At this time, the material enters the annular cavity under the action of its own gravity, avoiding the accumulation of the material at the feed port 110, thereby reducing the risk of the feed port 110 being blocked. Optionally, a stirring member 250 is provided in the annular groove 240. When the material in the annular cavity rotates with the distribution disk 200, the stirring member 250 can prevent the material from being deposited at the bottom of the feed disk 100. Of course, the stirring member 250 may not be provided.

[0023] Optionally, the stirring member 250 can be a plate-like structure, and both ends of the stirring member 250 are respectively connected to the side walls of the annular groove 240. The stirring member 250 can be tilted to play a guiding role to prevent the material from sticking to the stirring member 250, which is beneficial to improving its stirring efficiency.

[0024] Optionally, the feed tray 100 is provided with a drain port 170 which is in communication with the annular cavity. When the filling pump stops working, the material in the annular cavity can be discharged from the drain port 170, thereby preventing the material in the annular cavity from being deposited or solidified.

[0025] In another optional embodiment, the feed tray 100 includes a connected annular body 130 and a protective cover plate 140, the protective cover plate 140 is sealedly arranged on one side of the annular body 130 to form a receiving space, the protective cover plate 140 forms a first side wall 120, that is, the protective cover plate 140 is provided with a avoidance hole 121, and the protective cover plate 140 is sealed with the first side surface 210 of the distribution plate 200. One end of the supercharger 300 is sealed with the protective cover plate 140, and optionally, when the supercharger 300 is a cylinder or a hydraulic cylinder, the cylinder barrel of the supercharger 300 is sealed with the protective cover plate 140. The distribution plate 200 can directly rotate with the inner ring surface of the annular body 130; or, in other embodiments, the filling pump further includes a first bearing 510, the first bearing 510 is arranged on the inner ring surface of the annular body 130, and the protective cover plate 140 abuts against the first bearing 510 to prevent the first bearing 510 from moving along the axial direction of the annular body 130. The distribution plate 200 is rotatably connected to the feed plate 100 via the first bearing 510 , which can not only improve the rotation flexibility of the distribution plate 200 , but also prevent the distribution plate 200 and the annular body 130 from being worn. Optionally, in the axial direction of the annular body 130 , first bearings are provided on both sides of the vertical plane where the feed port 110 is located. In this case, the space between the two oppositely arranged first bearings can be used to set other structures, which can improve the utilization rate of the accommodating space of the feed tray 100 .

[0026] Optionally, the feed tray 100 further includes a base 160 , and the annular body 130 is disposed on the base 160 .

[0027] In a further optional embodiment, the outer peripheral surface of the distribution plate 200 is provided with an annular groove 240, and the annular groove 240 and the inner surface of the feed plate 100 form an annular cavity, and the feed port 110 is connected to the feed bin 220 through the annular cavity. In the axial direction of the annular body 130, annular shielding parts 150 are provided on both sides of the annular cavity opposite to each other, and the outer annular surface of the annular shielding part 150 is connected to the inner annular surface of the annular body 130, and the inner annular surface of the annular shielding part 150 is sealed with the outer annular surface of the distribution plate 200, and the annular shielding part 150 is opposite to the first bearing 510. At this time, the annular shielding part 150 can block the material in the annular cavity from entering the first bearing 510, thereby protecting the first bearing 510. Of course, the annular shielding part 150 can also be replaced by a seal.

[0028] It should be noted that the size of the annular shielding portion 150 can be selected according to the particle size in the material, and the embodiment of the present application does not impose any specific limitation on this.

[0029] Optionally, the annular shielding portion 150 includes a shielding ring 151 and a sealing felt 152, the outer ring surface of the shielding ring 151 is connected to the inner ring surface of the annular body 130, the inner ring surface of the shielding ring 151 is gap-matched with the outer ring surface of the distribution plate 200, the inner ring surface of the shielding ring 151 is provided with a groove, and the sealing felt 152 is arranged in the groove. The sealing felt 152 is sealingly matched with the outer ring surface of the distribution plate 200. Since the sealing felt 152 is soft and flexible, its internal fiber structure gives it a certain elasticity and compressibility, and it can deform when subjected to force; at the same time, the fibers of the sealing felt 152 can absorb the lubricating oil or grease in the contact medium to form a lubricating film, reduce friction, thereby improving the sealing effect of the annular shielding portion 150, and preventing large-particle filling medium inside the annular cavity from leaking to the outside from the gap between the shielding ring 151 and the distribution plate 200.

[0030] Optionally, the shielding ring 151 and the annular body 130 can be an integrated structure, thereby reducing the difficulty of sealing the feed tray 100 during assembly; the shielding ring 151 and the annular body 130 can also be a split structure, which facilitates the mold opening and molding of the two during the manufacturing process.

[0031] In a further optional embodiment, the filling pump also includes a sealing ring 530, which is supported on the inner ring surface of the annular body 130. In the axial direction of the annular body 130, the sealing ring 530 is sealingly arranged between the first bearing 510 and the annular shielding portion 150. The distribution plate 200 is sealed and cooperated with the first bearing 510 through the sealing ring 530, thereby isolating the annular cavity from the first bearing 510 to prevent the material in the annular cavity from entering the first bearing 510, so as to further protect the first bearing 510; and, because the annular cavity is connected to the accommodating cavity of the supercharger 300 through the feed bin 220, when the supercharger 300 sucks material, a certain pressure will be generated in the annular cavity, which will expand the sealing ring 530, thereby improving the sealing performance of the sealing ring 530.

[0032] In a further optional example, the filling pump further includes a wear-resistant ring 540, which is detachably sleeved on the distributor plate 200. In the radial direction of the annular body 130, the wear-resistant ring 540 and the sealing ring 530 are sleeved in sequence, and the distributor plate 200 is sealed with the sealing ring 530 through the wear-resistant ring 540. The distributor plate 200 can drive the wear-resistant ring 540 to rotate together during the rotation process. At this time, the wear-resistant ring 540 can rotate relative to the sealing ring 530, and there is a dynamic friction between the two. The setting of the wear-resistant ring 540 can prevent the distributor plate 200 from being worn, thereby protecting the distributor plate 200; when the wear-resistant ring 540 is worn, the wear-resistant ring 540 can be removed and replaced.

[0033] Optionally, the wear-resistant ring 540 may be provided with an inclined surface, and the inclined surface of the wear-resistant ring 540 cooperates with the outer peripheral surface of the distribution plate 200, and the inclined surface of the wear-resistant ring 540 may play a guiding role during the assembly of the wear-resistant ring 540. It should be noted that the inclination angle of the inclined surface of the wear-resistant ring 540 may be selected according to actual needs, and the embodiment of the present application does not impose specific restrictions on this.

[0034] In another optional embodiment, the distribution plate 200 includes a connected plate body 260 and a sealing cover 270. The sealing cover 270 is provided with a first sealing groove 271 on one side facing the plate body 260. A first sealing ring is provided in the first sealing groove 271. The sealing cover 270 is sealed with the plate body 260 through the first sealing ring. Optionally, the sealing cover 270 is provided with a deformation protrusion 273 on one side facing the protective cover plate 140. The protective cover plate 140 presses on the deformation protrusion 273 to deform the deformation protrusion 273. At this time, the protective cover plate 140 and the sealing cover 270 are sealed; optionally, the sealing cover 270 can be made of PEEK (Polyetheretherketone) alloy material, which uses the self-lubricating properties of the material itself to reduce the friction between the sealing cover 270 and the protective cover plate 140. The sealing cover 270 can store a certain amount of elastic potential energy after installation. When the deformation protrusion 273 is slightly worn, the first sealing ring on the back of the sealing cover 270 can open the sealing cover 270 so that the deformation protrusion 273 continues to maintain the sealing performance.

[0035] In other embodiments, a second sealing groove 272 is provided on one side of the sealing cover 270 facing the protective cover plate 140, a second sealing ring is provided in the second sealing groove 272, and the sealing cover 270 is sealed with the protective cover plate 140 through the second sealing ring. After the sealing cover 270 is installed, a certain amount of elastic potential energy can be stored. When the second sealing ring is slightly worn, the first sealing ring on the back of the sealing cover 270 can prop the sealing cover 270 open, so that the second sealing ring continues to maintain the sealing performance.

[0036] In the above scheme, the setting of the sealing cover 270 can protect the disk body 260 and prevent it from being worn. The sealing cover 270 can be replaced when it is worn; the first surface of the sealing cover 270 is sealed with the protective cover plate 140 through the deformation protrusion 273 or the second sealing ring, and the second surface of the sealing cover 270 (i.e., the back surface in the previous text) is sealed with the disk body 260 through the first sealing ring, which is beneficial to improving the sealing of the feed bin 220 and the discharge bin 230.

[0037] Optionally, the protective cover plate 140 is provided with a lubricating oil hole 141 connected to the second sealing groove 272, so as to input lubricating oil into the second sealing groove 272, avoid dry friction between the sealing cover 270 and the protective cover plate 140, and thus extend the service life of the sealing cover 270. Optionally, the number of the lubricating oil hole 141 may be one, or the number of the lubricating oil holes 141 may be at least two, and the lubricating oil holes 141 are sequentially arranged at intervals along the track of the second sealing groove 272, so as to improve the uniformity of the distribution of the lubricating oil in the second sealing groove 272.

[0038] In another optional embodiment, the filling pump further includes a shear ring 550 and a shear plate 560 , wherein the shear ring 550 is disposed on the inner wall of the avoidance hole 121 , and the shear plates 560 are disposed on the circumferential side walls of the annular body 130 of the feed bin 220 and the discharge bin 230 . During the rotation of the distribution disc 200, particles in the material will be sheared at the openings of the accommodating chamber of the supercharger 300, the feed bin 220 and the discharge bin 230 of the distribution disc 200. After the filling pump has been running for a period of time, the openings of the accommodating chamber, the feed bin 220 and the discharge bin 230 will be severely worn, which may easily lead to pressure leakage. Therefore, by providing a shear ring 550 and a shear plate 560, this can prevent the openings of the accommodating chamber, the feed bin 220 and the discharge bin 230 from being worn, so as to play a protective role; when the shear ring 550 and the shear plate 560 are worn due to the shear force, they can be replaced to avoid the overall replacement of the supercharger 300 and the distribution disc 200, thereby reducing costs.

[0039] In an optional embodiment, the feed bin 220 and the discharge bin 230 are arranged at intervals around the central axis of rotation of the distribution plate 200. At this time, the output shaft of the driving member 400 coincides with the central axis of the distribution plate 200, and the two are connected, which facilitates the arrangement of the driving member 400. The distribution plate 200 has a first side surface 210 and a second side surface 280 arranged opposite to each other, and the second side surface 280 is provided with a discharge port 231. At this time, the conveying pipeline and the booster 300 for conveying materials are respectively arranged on two opposite sides of the feed plate 100. The filling pump also includes a first discharge pipe 610 and a second discharge pipe 620 that are rotatably connected. The first end of the first discharge pipe 610 is connected to the discharge port 231, and the second end of the first discharge pipe 610 is inserted into the second discharge pipe 620, and the two are sealed and matched, that is, the first discharge pipe 610 and the second discharge pipe 620 form the material conveying pipeline described above. The distribution plate 200 can drive the first discharge pipe 610 to rotate relative to the second discharge pipe 620, and the central axis of the second discharge pipe 620 coincides with the rotational central axis of the distribution plate 200. The first discharge pipe 610 and the second discharge pipe 620 in this solution are connected by plugging, which is not only convenient for the connection between the two, but also convenient for the setting of the sealing structure. Of course, the end face of the first discharge pipe 610 and the end face of the second discharge pipe 620 can be directly rotated and matched, and at this time, a flange or other structure can be installed at the connection between the two for sealing connection.

[0040] Optionally, the first discharge pipe 610 may be a bent structure to facilitate connection with the second discharge pipe 620 .

[0041] Optionally, the outer circumferential surface of the first discharge pipe 610 is provided with a receiving groove, and a sealing ring is provided in the receiving groove. The sealing ring is sealed with the inner circumferential surface of the second discharge pipe 620, that is, the first discharge pipe 610 is sealed and connected to the second discharge pipe 620 through the sealing ring; further optionally, the second discharge pipe 620 is provided with a lubricating oil hole connected to the receiving groove, so that an oil seal is passed between the first discharge pipe 610 and the second discharge pipe 620, thereby improving the sealing between the two.

[0042] In a further optional embodiment, the filling pump further includes a second bearing 630 and a positioning ring 640. The second bearing 630 is disposed between the outer circumference of the first discharge pipe 610 and the inner circumference of the second discharge pipe 620. The first discharge pipe 610 is rotatably connected to the second discharge pipe 620 through the second bearing 630, which can improve the rotation flexibility of the first discharge pipe 610 relative to the second discharge pipe 620. The positioning ring 640 is sleeved on the outer circumference of the first discharge pipe 610, the positioning ring 640 is close to the pipe mouth of the second discharge pipe 620, and the positioning ring 640 is abutted against the second bearing 630 to prevent the second bearing 630 from moving along the axial direction of the second discharge pipe 620 and causing the first discharge pipe 610 to separate from the second discharge pipe 620. Of course, the positioning ring 640 may not be provided, and the outer circumference of the first discharge pipe 610 and the second bearing 630 may be welded and fixed.

[0043] Optionally, the positioning ring 640 may be a retaining spring, which may absorb vibration and impact generated during the rotation of the first discharge pipe 610 , thereby improving the stability of the second bearing 630 .

[0044] Optionally, the sealing ring is located on the side of the second bearing 630 away from the positioning ring 640. At this time, the positioning ring 640, the second bearing 630 and the sealing ring play a sealing role in turn, but the sealing ring, as the last sealing structure, has a better sealing effect than the first two sealing structures, thereby improving the sealing of the connection between the first discharge pipe 610 and the second discharge pipe 620; and the sealing ring is protected by the positioning ring 640 and the second bearing 630, so its service life can be extended.

[0045] Optionally, the filling pump can be supported on the bracket 700 to prevent it from being placed directly on the ground, thereby protecting the filling pump.

[0046] Optionally, the filling pump further includes a hopper 800 , which is disposed at the feed inlet 110 to facilitate the material to enter the feed tray 100 .

[0047] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
