Description

Technical Field

[0001] This invention relates to the field of cylindrical container disassembly and assembly technology, and in particular to a powder container disassembly device and its usage method. Background Technology

[0002] In the mining industry, the reagents used in flotation workshops need to be prepared by mixing different reagent ratios. Currently, most powdered reagents in flotation workshops are stored in powder tanks, which have a certain wall thickness. Each time reagents are prepared and used, the tank walls need to be broken open manually with tools such as axes and crowbars. This is inefficient and poses the risk of inhaling toxic powder. In addition, improper operation of tools during the process of breaking open powder tanks can easily lead to personal injury accidents, which is dangerous.

[0003] Reference CN202420374952.9 A zirconium powder mixing barrel, wherein an external thread section is formed on the top of the barrel body, and an internal thread section matching the external thread section is formed on the inner peripheral wall of the barrel cover. The barrel cover is detachably connected to the barrel body through the external thread section and the internal thread section. A rotating control unit drives the barrel cover to be screwed in or out of the top of the barrel body.

[0004] However, most existing powder containers are sealed and non-removable for airtight transport, and are only forcibly opened at the user's location. Therefore, equipment is needed to clamp and dismantle the powder containers.

[0005] Therefore, the present invention proposes a powder barrel breaking device and its usage method. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides a powder barrel dismantling device and a method of use, which solves the technical problem of inconvenient dismantling and assembly of the outer wall of the powder barrel in the prior art.

[0007] The purpose of this invention is to provide a device for breaking open powder reagent tanks in flotation workshops, so as to overcome or improve the problems of low work efficiency, high operational danger, and easy release of toxic powder, harm to personnel health and environmental pollution caused by relying on manual use of tools such as axes and crowbars to break open the tank walls in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A powder barrel breaking device, comprising:

[0010] Fixed platform;

[0011] A gear and rack hydraulic lifting assembly is installed on a fixed platform; a lifting plate is installed on the top for vertical lifting and moving.

[0012] The demolition mechanism is mounted on a lifting plate; it includes a gripper component and a demolition component. The gripper component includes a hydraulic cylinder, a gripper, and a constraint component. The hydraulic cylinder pushes the constraint component to open and close the gripper. The demolition component is mounted outside the gripper and connected to the gripper.

[0013] In a further technical solution, the gear and rack hydraulic lifting assembly includes a base, on which a lifting hydraulic cylinder is mounted. The lifting hydraulic cylinder is arranged vertically and its top is connected to the lifting plate.

[0014] Fixed cylinders are installed on both sides of the lifting hydraulic cylinder, and a movable rod is telescopically installed inside the fixed cylinder. The top of the movable rod is connected to the lifting plate.

[0015] The gear and rack hydraulic lifting assembly also includes a support base, the bottom of which is connected to a fixed platform; a transmission structure is installed between the two ends of the support base and the movable rod.

[0016] In a further technical solution, the transmission structure includes a transmission gear, a rack portion is provided on one side of the movable rod, and an installation port is provided on the fixed cylinder; the transmission gear and the rack portion are meshed and connected at the installation port.

[0017] The support base includes a horizontal shaft and a constraint plate. The constraint plate is connected to the fixed platform and is provided with two sets of horizontal shafts that support each other. The horizontal shaft and the constraint plate are connected by a rolling bearing.

[0018] Both ends of the horizontal shaft are connected to transmission gears via keyways.

[0019] In a further technical solution, the demolition mechanical component includes a fixed base, in which a position cavity one and a position cavity two are provided, and a hydraulic cylinder one is installed in the position cavity one, with the output end of the hydraulic cylinder one extending into the position cavity two.

[0020] A sliding rod is installed in position cavity two, and constraint members are installed at both ends of the sliding rod; the output end of hydraulic cylinder one drives the sliding rod to extend and retract.

[0021] Connection ports are provided on both sides of the fixed seat at the end opposite to the lifting plate. The gripper includes a gripper body plate, and the end of the gripper body plate is installed in the connection port. The two sets of gripper body plates face each other for clamping the powder bucket.

[0022] In a further technical solution, the constraint member includes an upper crank and a lower crank, and a sliding sleeve is slidably mounted on the sliding rod; one end of the upper crank and the lower crank are hinged to the fixed seat, and the other end is respectively hinged to the upper and lower sides of the sliding sleeve.

[0023] In a further technical solution, a hydraulic station is installed on the fixed platform, and the hydraulic station is connected to the lifting hydraulic cylinder and the hydraulic cylinder one respectively;

[0024] The fixed platform includes a sliding section that extends to the bottom edge of the fixed platform; a movable baffle is installed on the sliding section to movably block the powder barrel.

[0025] Discharge boxes are installed on both sides of the fixed platform, and a screen layer is installed on top of the discharge boxes.

[0026] In a further technical solution, two sets of claw plates are equipped with fixing posts, and a sliding plate is installed on the top of the two sets of fixing posts. The bottom of the sliding plate is equipped with a groove to restrain the top of the two sets of fixing posts.

[0027] A drive motor is installed at the top center of the slide plate. The output end of the drive motor passes through the slide plate and is connected to a rotating shaft via a coupling. A working rod is hinged to the shaft of the rotating shaft, and a cone is provided at the bottom end of the working rod. The drive motor drives the working rod to rotate, thereby driving the cone to rotate.

[0028] In a further technical solution, an expansion ring is provided in the middle of the working rod, and a short rotating shaft is provided inside the expansion ring to pass through the rotating shaft; a position plate is fixedly installed at the bottom of the rotating shaft, and a lifting cylinder is installed on the position plate. The output end of the lifting cylinder is set upward, and the output end is hinged to the end of the working rod away from the cone.

[0029] The output end of the lifting cylinder lifts and pushes the bottom of the cone down to a height below the position plate.

[0030] In a further technical solution, a pointed cone is provided on the opposite side of the claw body plate, and the pointed cone is used to squeeze the outer wall of the powder barrel.

[0031] A method for breaking up a powder barrel using a breaking device includes the following steps:

[0032] Step 1: The gear and rack hydraulic lifting assembly controls the lifting hydraulic cylinder through the hydraulic station. The lifting hydraulic cylinder lifts and moves the movable rods on both sides upward, and the transmission gear meshes with the rack.

[0033] Step 2: Use transport equipment to place the powder bucket on top of the sliding section. At this time, the movable baffle limits the powder bucket and prevents it from falling off the sliding section.

[0034] Step 3: The hydraulic station controls the hydraulic cylinder one to retract first. The upper and lower cranks move on the slide rod under the drive of the hydraulic cylinder one, so that the distance between the two sets of claw plates is widened. Simultaneously, the lifting hydraulic cylinder retracts until the claw plates are located on both sides of the powder barrel.

[0035] Step 4: The hydraulic cylinder pushes outward, forcing the distance between the two sets of claw plates to narrow until they squeeze the outer wall of the powder barrel; the squeezing continues, causing the pointed cone to insert into the outer wall.

[0036] Step 5: First, drive the lifting cylinder upward so that the cone at the end of the working rod is driven into the powder bucket. Then, drive the motor to drive the rotating shaft to rotate, thereby rotating the working rod and splitting the top of the powder bucket.

[0037] Step 6: The output end of the lifting cylinder is reset, and the distance between the two sets of claw plates is widened until they are reset;

[0038] Step 7: Clean the discharge box under the fixed platform regularly.

[0039] The present invention has the following beneficial effects:

[0040] 1. When the hydraulic cylinder of the present invention moves back and forth, it moves on the slide rod via the upper and lower cranks, simultaneously driving two detachable claw plates to clamp or expand, thereby achieving the positioning and breaking of the powder container. In this embodiment, a sharp cone is provided inside the claw, which can break through the outer wall of the powder container when the claw clamps, allowing the powder to flow out.

[0041] 2. In this invention, when the powder bucket is placed on the sliding part of the fixed platform, a screen layer is installed on the surface of the fixed platform, and a box-type discharge box is located below the screen layer. The sprayed powder falls into the discharge box through the screen layer. Pull rings are provided on both sides of the fixed platform. When a certain amount is accumulated, the powder can be recycled. This also avoids the problems of low efficiency and high operational danger of manually dismantling the powder bucket.

[0042] 3. This invention features two sets of fixed columns that move with the claw body. The tops of the fixed columns are constrained by a sliding plate to ensure that clamping or expansion is horizontal and that transmission is consistent. Secondly, a drive motor is installed in the middle of the slide rod to drive the rotating shaft and the position plate to rotate, ensuring that the working rod on the rotating shaft rotates. First, the lifting cylinder moves one end of the working rod upward. Through the hinge of the working rod on the rotating shaft, the other end descends, thus allowing the cone to penetrate the powder bucket downward. As it rotates with the rotating shaft, it cuts the outer wall of the powder bucket in an arc or circle, thus opening the powder bucket. Attached Figure Description

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0062] Example 1

[0063] like Figure 1-5 As shown, this is one embodiment of the present invention, a powder barrel breaking device, comprising:

[0064] Fixed platform 3; used to support gear and rack hydraulic lifting assembly 1 and demolition mechanical assembly 2.

[0065] The gear and rack hydraulic lifting assembly 1 is installed on the fixed platform 3; a lifting plate 11 is installed on the top for vertical lifting and moving the lifting plate 11.

[0066] The demolition mechanism 2 is mounted on the lifting plate 11. It includes a gripper 22 and a demolition component. The gripper 22 includes a hydraulic cylinder 21, a gripper 22, and a constraint member. The hydraulic cylinder 21 pushes the constraint member to open and close the gripper 22. The demolition component is installed outside the gripper 22 and connected to it. A pointed cone 28 is provided on one side of the gripper body 221, which is used to squeeze the outer wall of the powder container 100. Different shapes and types of demolition tools can also be installed and removed on the inside of the gripper to facilitate the demolition of powder containers of different sizes and with different needs.

[0067] like Figure 2 As shown, the gear and rack hydraulic lifting assembly 1 includes a base 12, on which a lifting hydraulic cylinder 13 is mounted. The lifting hydraulic cylinder 13 is vertically arranged and its top is connected to the lifting plate 11. The inlet and outlet oil pipes of the lifting hydraulic cylinder are connected to a hydraulic station to control the lifting and lowering of the lifting hydraulic cylinder. The hydraulic station controls the oil circuit through an electro-hydraulic valve group, and the electro-hydraulic control can be achieved through an electro-hydraulic control station and an external controller.

[0068] like Figure 2 As shown, fixed cylinders 14 are installed on both sides of the lifting hydraulic cylinder 13, and a movable rod 15 is telescopically installed inside the fixed cylinder 14. The top of the movable rod 15 is connected to the lifting plate 11; in this embodiment, as shown... Figure 2 In this design, both the movable rod and the fixed cylinder are circular or annular, and are not limited to this shape.

[0069] The gear and rack hydraulic lifting assembly 1 also includes a support base, the bottom of which is connected to the fixed platform 3; a transmission structure is installed between the two ends of the support base and the movable rod 15.

[0070] like Figure 2 The transmission structure includes a transmission gear 16, a rack portion 17 is provided on one side of the movable rod 15, and an installation port 18 is provided on the fixed cylinder 14; the transmission gear 16 and the rack portion 17 are meshed and connected at the installation port 18.

[0071] The support base includes a horizontal shaft 19 and a constraint plate 110. The constraint plate 110 is connected to the fixed platform 3 and has two sets of bearings that jointly support the horizontal shaft 19. The horizontal shaft 19 and the constraint plate 110 are connected by a rolling bearing. The constraint plate is T-shaped and its bottom is fixed to the fixed platform by bolts. The upper part of the constraint plate has an opening and a rolling bearing is installed thereon. The outer ring of the rolling bearing is connected to the inner wall of the opening, and the inner ring is fixedly connected to the horizontal shaft. The rolling bearing ensures the horizontal shaft is installed horizontally and rotates effectively. Both ends of the horizontal shaft 19 are keyway connected to transmission gears 16, which mesh with the rack and pinion sections through the mounting openings.

[0072] like Figure 3 As shown, the demolition mechanical component 2 includes a fixed base 23, within which are a position cavity one and a position cavity two. A hydraulic cylinder one 21 is installed in position cavity one, and the output end of the hydraulic cylinder one 21 extends into position cavity two. Position cavity one is used to install the hydraulic cylinder one, which is connected to a hydraulic station and controls the hydraulic circuit through the solenoid valve group and hydraulic valve group of the hydraulic station, thereby performing the filling and draining actions of the hydraulic cylinder one.

[0073] A slide rod 24 is installed in the second position cavity, and constraint members are installed at both ends of the slide rod 24; the output end of the hydraulic cylinder 21 drives the slide rod 24 to extend and retract; closing plates can be set at both ends of the slide rod to prevent the slide sleeve from disengaging from the slide rod.

[0074] like Figure 5 The fixed base 23 has connection ports 231 on both sides of the end facing away from the lifting plate 11. The gripper 22 includes a gripper body plate 221, and the end of the gripper body plate 221 is installed in the connection port 231. The two sets of gripper body plates 221 face each other for clamping the powder barrel 100. The powder barrel can be a wine barrel, oil barrel or other cylindrical shape, and it is necessary to ensure that the two sides are symmetrically arranged and that the outer wall can be opened.

[0075] like Figure 4 and 5 As shown, the constraint includes an upper crank 25 and a lower crank 26, and a sliding sleeve 27 is slidably mounted on the sliding rod 24; one end of the upper crank 25 and the lower crank 26 are hinged to the fixed seat 23, and the other end is respectively hinged to the upper and lower sides of the sliding sleeve 27.

[0076] The fixed platform 3 is equipped with a hydraulic station 4, which is connected to the lifting hydraulic cylinder 13 and the hydraulic cylinder 21 respectively.

[0077] When the hydraulic cylinder of this invention moves back and forth, it moves on the slide rod via the upper and lower cranks, simultaneously driving two detachable claw plates to clamp or expand, thereby achieving the positioning and breaking of the powder barrel. In this embodiment, a sharp cone is provided inside the claw, which can break the outer wall of the powder barrel when the claw is clamped, allowing the powder to flow out. During mineral processing and flotation, the powder is placed into the flotation box, where it automatically flows out as powder reagent. After use, the powder barrel is retrieved for further processing.

[0078] Example 2

[0079] like Figure 6 As shown, in another embodiment of the present invention, based on embodiment 1, the fixed platform 3 includes a sliding part 31, which extends to the bottom edge of the fixed platform 3; a movable baffle 32 is installed on the sliding part 31, which is used to movably block the powder bucket 100; the movable baffle can be hingedly installed in the sliding part, and a torsion spring is installed at the hinge position, as is conventionally... Figure 6 The movable baffle shown can be pushed upwards along the sliding section to its top by pushing the powder bucket, while the movable sieve plate can rotate inwards but not outwards. Discharge boxes 33 are installed on both sides of the fixed platform 3, and a screen layer 34 is provided on top of the discharge box 33.

[0080] In this embodiment, when the powder canister is placed on the sliding section of the fixed platform, some powder may spill onto the platform after the canister is broken. A screen layer is installed on the surface of the fixed platform, and a box-type discharge box is located below the screen layer. The sprayed powder passes through the screen layer and falls into the discharge box. Pull rings are provided on both sides of the fixed platform, allowing the powder to be recovered after a certain amount has accumulated. This avoids the problems of low efficiency and high operational risks associated with manually breaking the powder canister.

[0081] Example 3

[0082] like Figure 7-11 As shown, another embodiment of the present invention is provided. Based on embodiment 1, two sets of claw plates 221 are equipped with fixing posts 51, and two sets of fixing posts 51 are equipped with a sliding plate 52 on their tops. The bottom of the sliding plate 52 is equipped with a groove for restraining the tops of the two sets of fixing posts 51.

[0083] like Figure 7 and 8As shown, a drive motor 53 is mounted on the top center of the slide plate 52. The output end of the drive motor 53 passes through the slide plate 52 and is connected to a rotating shaft 54 ​​via a coupling. A working rod 55 is hinged to the shaft of the rotating shaft 54, and a cone 56 is provided at the bottom end of the working rod 55. The drive motor 53 drives the working rod 55 to rotate, thereby driving the cone 56 to rotate. The cone is used to penetrate the powder container, so it needs to be made of a metal alloy with sufficient hardness, such as a nickel-based alloy or a chromium-based alloy.

[0084] like Figure 11 As shown, a diameter-expanding ring 551 is provided in the middle of the working rod 55, and a short rotating shaft 552 is provided inside the diameter-expanding ring 551, passing through the rotating shaft 54; a position plate 57 is fixedly installed at the bottom of the rotating shaft 54, and a lifting cylinder 58 is installed on the position plate 57. The output end of the lifting cylinder 58 is set upward, and the output end is hinged to the end of the working rod 55 away from the cone 56; the output end of the lifting cylinder 58 lifts and pushes the bottom of the cone 56 down to a height lower than the position plate 57.

[0085] This invention employs two sets of fixed columns that move with the claw body. The tops of these fixed columns are constrained by sliding plates, ensuring horizontal movement during clamping or expansion and guaranteeing consistent transmission. Secondly, a drive motor installed in the middle of the sliding rod rotates the rotating shaft and position plate, allowing the working rod on the rotating shaft to rotate and engage with the powder container lid. First, the lifting cylinder moves one end of the working rod upwards. The working rod's hinge to the rotating shaft causes the other end to descend, allowing the cone to penetrate the powder container. As it rotates with the rotating shaft, it creates an arc or circumference that cuts through the outer wall of the powder container, opening it. A groove is provided on the working rod at the top connection point of the lifting cylinder, allowing for an expansion of the lifting angle of the working rod.

[0086] A method for breaking up a powder barrel using a breaking device includes the following steps:

[0087] Step 1: The gear and rack hydraulic lifting assembly 1 controls the lifting hydraulic cylinder 13 through the hydraulic station 4. The lifting hydraulic cylinder 13 lifts and moves the movable rods 15 on both sides upward, and the transmission gear 16 meshes with the rack part 17.

[0088] Step 2: Use a transport device to place the powder barrel 100 on top of the sliding part 31. At this time, the movable baffle 32 blocks the powder barrel 100 to form a limit, preventing the powder barrel 100 from falling off the sliding part 31.

[0089] Step 3: The hydraulic station 4 controls the hydraulic cylinder 21 to retract first. The upper crank 25 and the lower crank 26 move on the slide bar 24 under the drive of the hydraulic cylinder 21, so that the distance between the two sets of claw plates 221 is increased. Simultaneously, the lifting hydraulic cylinder 13 retracts until the claw plates 221 are located on both sides of the powder barrel 100.

[0090] Step 4: Hydraulic cylinder 21 pushes outward, forcing the distance between the two sets of claw plates 221 to decrease until it squeezes the outer wall of the powder barrel 100; continuous squeezing causes the pointed cone 28 to insert into the outer wall.

[0091] Step 5: First, drive the lifting cylinder 58 upward so that the cone 56 at the end of the working rod 55 is inserted into the powder bucket 100. Then, drive the motor 53 to drive the rotating shaft 54 ​​to rotate, thereby rotating the working rod 55 and splitting the top of the powder bucket 100.

[0092] Step 6: The output end of the lifting cylinder 58 is reset, and the distance between the two sets of claw plates 221 is increased until it is reset;

[0093] Step 7: Clean the discharge box 33 under the fixed platform 3 regularly.

[0094] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. A powder barrel breaking device according to claim 8, characterized in that, A pointed cone (28) is provided on the opposite side of the claw plate (221), and the pointed cone (28) is used to squeeze the outer wall of the powder barrel (100).

10. A method for dismantling a powder barrel dismantling device, characterized in that, Includes the following steps: Step 1: The gear and rack hydraulic lifting assembly (1) controls the lifting hydraulic cylinder (13) through the hydraulic station (4). The lifting hydraulic cylinder (13) lifts and lowers, driving the movable rods (15) on both sides to move upward, and the transmission gear (16) meshes with the rack part (17). Step 2: Use a transport device to place the powder barrel (100) on top of the sliding part (31). At this time, the movable baffle (32) limits the powder barrel (100) to prevent it from falling off the sliding part (31). Step 3: The hydraulic station (4) controls the hydraulic cylinder 1 (21) to retract first. The upper crank (25) and lower crank (26) move on the slide bar (24) under the drive of the hydraulic cylinder 1 (21), so that the distance between the two sets of claw plates (221) is increased. Simultaneously, the lifting hydraulic cylinder (13) retracts until the claw plates (221) are located on both sides of the powder barrel (100). Step 4: Hydraulic cylinder 1 (21) pushes outward, forcing the distance between the two sets of claw plates (221) to decrease until the outer wall of the powder barrel (100) is squeezed; continuous squeezing causes the cone (28) to insert into the outer wall; Step 5: First, drive the lifting cylinder (58) upward so that the cone (56) at the end of the working rod (55) is inserted into the powder bucket (100). Then, drive the motor (53) to drive the rotating shaft (54) to rotate, thereby rotating the working rod (55) and splitting the top of the powder bucket (100). Step 6: The output end of the lifting cylinder (58) is reset, and the distance between the two sets of claw plates (221) is increased until it is reset; Step 7: Clean the discharge box (33) under the fixed platform (3) regularly.
