Description

Technical Field

[0001] This invention relates to the field of chemical technology, specifically to a device for discharging raw materials in drums for chemical applications. Background Technology

[0002] The chemical drum raw material unloading device is a highly integrated, safe, and automated piece of equipment widely used in the chemical, pharmaceutical, food, and daily chemical industries. With continuous technological advancements, the unloading device will become more intelligent and precise, meeting the increasingly stringent requirements for efficiency, safety, and environmental protection in industrial production processes.

[0003] Patent publication number CN221396166U relates to a barrelled raw material pouring device, including a movable frame for moving barrelled raw materials. The top of the movable frame has a lifting frame for raising and lowering the barrelled raw materials, a clamping and fixing frame for connecting the barrelled raw materials, and a limiting frame for clamping and fixing the barrelled raw materials. The limiting frame has a top control component on its outer side. The top control component includes an arc-shaped plate, a first inner bolt, and a second outer bolt. The arc-shaped plate is located above the raw material barrel and does not contact the raw material barrel. It allows the top clamping plates to be distributed on the inner and outer walls of the raw material barrel. The three top clamping plates are distributed at different positions on the raw material barrel, which can control the top position of the raw material barrel. The limiting cavity between the first inner bolt and the second outer bolt restricts the pouring, so that the inner wall of the raw material barrel is evenly stressed. This not only stably restricts the pouring of raw material barrels but also prevents damage to the inner wall of the barrel.

[0004] In the aforementioned patent, the limiting cavity between the first inner bolt and the second outer bolt can make the inner wall of the raw material barrel evenly stressed. This not only stably limits the pouring of raw material from the barrel but also prevents damage to the inner wall. However, when the chemical barrel is turned over, the valve needs to be manually turned to make the barrel turn over, which is time-consuming and laborious. At the same time, it is difficult to control the angle of the chemical barrel during the turning process. If the angle is too large, the chemical raw materials will fly out, causing environmental pollution. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a chemical drum-type raw material unloading device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chemical drum raw material unloading device, comprising a support, a hydraulic cylinder fixedly installed at the bottom of the inner wall of the support, a first U-shaped rod fixedly installed at the output end of the hydraulic cylinder, a round shaft fixedly installed on the inner wall of the support, and a sliding plate fixedly installed at the top of the support; further comprising a tilting device, a fixing device, and a reduction device; wherein, the tilting device comprises a fixing block, a first gear, a belt, a second gear, a third gear, a square block, a circular clamp, and a first rack; the fixing block is fixedly installed at the top of the first U-shaped rod; the first gear is rotatably installed on the side of the fixing block away from the round shaft; the square block... The first U-shaped rod is fixedly installed on the top. The second gear is rotatably installed on the outer wall of the square block. The first gear is connected to the second gear via a belt. The third gear rotates through the inner and outer walls of the square block and meshes with the second gear. The circular clamp is fixedly installed on the circumference of the third gear. The first rack is fixedly installed on the outer wall of the bracket and meshes with the first rack. The first U-shaped rod moves upward, causing the fixed block to move upward. The fixed block moves upward, causing the first gear to move upward. The first gear moves upward and meshes with the first rack, rotating. The rotation of the first gear drives the belt to rotate, and the rotation of the belt drives the second gear to rotate.

[0007] According to the above technical solution, the flipping device further includes a limiting rod, a long rod, and a pressing rod. The limiting rod is slidably installed on the inner wall of the sliding plate. The long rod is fixedly installed on the side of the limiting rod away from the circular clamp. One end of the pressing rod is rotatably installed on the top of the long rod, and the other end of the pressing rod is rotatably connected to the bottom of the first U-shaped rod. The first U-shaped rod moves upward, causing the pressing rod to move upward. The upward movement of the pressing rod causes the long rod to move closer to the circular clamp. The movement of the long rod closer to the circular clamp causes the limiting rod to move closer to the circular clamp.

[0008] According to the above technical solution, the first U-shaped rod is slidably connected to the circumferential surface of the circular shaft, and two long rods are provided. The two long rods are symmetrically distributed around the center of the limiting rod, which facilitates the up and down sliding of the first U-shaped rod.

[0009] According to the above technical solution, the fixing device includes a sliding rod, an L-shaped clamping rod, a first clamping plate, and a second clamping plate. The sliding rod is slidably installed on the outer wall of the circular clamp. The L-shaped clamping rod is fixedly installed on the side of the sliding rod near the circular clamp. The first clamping plate is fixedly installed on the side of the sliding rod near the sliding plate. The second clamping plate is fixedly installed on the outer wall of the circular clamp. The sliding rod moves downward, causing the L-shaped clamping rod to move downward, and the downward movement of the L-shaped clamping rod limits and clamps the chemical drum.

[0010] According to the above technical solution, the fixing device further includes a second rack, an L-shaped rack, a rotating shaft, a fourth gear, and a reset block. The second rack is fixedly installed on the side of the limiting rod near the circular clamp. The L-shaped rack is slidably installed on the inner wall of the sliding plate. The rotating shaft is fixedly installed on the inner wall of the sliding plate. The fourth gear is rotatably installed on the circumferential surface of the rotating shaft. The reset block is fixedly installed on the side of the L-shaped rack near the sliding rod. The second rack meshes with the fourth gear, and the L-shaped rack meshes with the fourth gear. The second rack moves towards the circular clamp, causing the fourth gear to rotate. The rotation of the fourth gear causes the L-shaped rack to move away from the circular clamp. The movement of the L-shaped rack away from the circular clamp causes the reset block to move, and the reset block moves and disengages from the sliding rod.

[0011] According to the above technical solution, a first spring is provided between the first and second clamping plates, and the side of the sliding rod away from the circular clamp is a first inclined surface, which facilitates the reset of the sliding rod and the squeezing of the sliding rod.

[0012] According to the above technical solution, the deceleration device includes a second U-shaped rod, a cylinder, a disc, a vertical rod, a contact rod, a spring, and an arc-shaped block. The second U-shaped rod is fixedly installed on the top of the first U-shaped rod, the cylinder is fixedly installed on the bottom of the second U-shaped rod, the disc is slidably installed on the inner wall of the cylinder, the vertical rod is fixedly installed on the top of the disc, the contact rod is fixedly installed on the bottom of the vertical rod, the spring is fixedly installed on the top of the disc, and the arc-shaped block is fixedly installed on the inner wall of the cylinder. The sliding rod contacts and presses the contact rod, and the contact rod moves upward under the pressure. The upward movement of the contact rod drives the vertical rod to move upward, and the upward movement of the vertical rod drives the disc to move upward.

[0013] According to the above technical solution, the cylinder has an exhaust port at the top, and the side of the spring piece near the arc-shaped block is an arc surface, which facilitates the spring piece to move up and down to generate vibration.

[0014] This invention provides a device for discharging raw materials from drums used in the chemical industry. It has the following beneficial effects: (1) In this invention, the hydraulic rod is activated to drive the No. 1 U-shaped rod to move upward, which in turn drives the chemical drum to move upward, making it easier to pour the material. At the same time, the No. 1 U-shaped rod moves upward and drives the No. 1 gear to rotate. The rotation of the No. 1 gear drives the No. 3 gear to rotate, which flips the chemical drum to pour the material. This greatly reduces the reliance on manual labor, reduces the uncertainty and labor intensity in manual operation, improves work efficiency, and reduces labor costs. At the same time, the No. 1 U-shaped rod moves upward and drives the limit rod to move, which limits the flipping angle of the chemical drum to prevent the chemical raw materials from spilling, causing waste of raw materials and increasing production costs.

[0015] (2) In this invention, the L-shaped rack drives the reset block to move, so that the sliding rod moves downward and drives the L-shaped clamp to fix the chemical drum, preventing the chemical drum from slipping and loosening during the pouring process, causing chemical raw materials to splash and injure the workers, resulting in material waste and increased costs. At the same time, after the pouring is completed, the L-shaped rack moves in the opposite direction and drives the reset block to move, so that the sliding rod moves upward and releases the fixation of the chemical drum, making it convenient to take out the chemical drum, saving manpower and improving work efficiency.

[0016] (3) The invention uses a cylinder and a vertical rod to slow down the chemical drum turning, preventing the chemical drum from turning too fast and causing raw materials to splash out of the drum opening, which could injure workers, waste raw materials, and increase costs. The vibration generated by the contact between the spring and the arc block makes the raw materials in the chemical drum more clean, increases the unloading speed, reduces unloading time and residual amount, and improves production efficiency.

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 One embodiment of the present invention is: a chemical drum raw material unloading device, including a support 1, a hydraulic cylinder 2 fixedly installed at the bottom of the inner wall of the support 1, a first U-shaped rod 3 fixedly installed at the output end of the hydraulic cylinder 2, a round shaft 4 fixedly installed on the inner wall of the support 1, and a sliding plate 5 fixedly installed at the top of the support 1. The flipping device includes a fixed block 61, a first gear 62, a belt 63, a second gear 64, a third gear 65, a square block 66, a circular clamp 67, and a first rack 611. The fixed block 61 is fixedly installed on the top of the first U-shaped rod 3, and the first gear 62 is rotatably installed on the side of the fixed block 61 away from the round shaft 4. The square block 66... Gear 6 is fixedly installed on the top of U-shaped rod 3. Gear 64 is rotatably installed on the outer wall of square block 66. Gear 62 is connected to gear 64 via belt 63. Gear 65 rotates through the inner and outer walls of square block 66. Gear 64 meshes with gear 65. Ring clamp 67 is fixedly installed on the circumference of gear 65. Rack 611 is fixedly installed on the outer wall of bracket 1. Gear 62 meshes with rack 611. The chemical drum is flipped by gears 62, 64 and 65, which reduces the uncertainty and labor intensity of manual operation and improves work efficiency.

[0021] The overturning device also includes a limiting rod 68, a long rod 69, and a squeezing rod 610. The limiting rod 68 is slidably installed on the inner wall of the sliding plate 5. The long rod 69 is fixedly installed on the side of the limiting rod 68 away from the circular clamp 67. One end of the squeezing rod 610 is rotatably installed on the top of the long rod 69, and the other end of the squeezing rod 610 is rotatably connected to the bottom of the first U-shaped rod 3. The squeezing rod 610 drives the limiting rod 68 to move, thereby limiting the angle of the chemical drum overturning and preventing the chemical drum from overturning, causing raw material waste and increasing costs.

[0022] The first U-shaped rod 3 is slidably connected to the circumferential surface of the circular shaft 4. There are two long rods 69, which are symmetrically distributed around the center of the limiting rod 68 to facilitate the up and down sliding of the first U-shaped rod 3.

[0023] In this embodiment, when it is necessary to unload the raw materials from the chemical drum, the circular clamp 67 clamps the chemical drum. Simultaneously, the hydraulic cylinder 2 is activated, causing the first U-shaped rod 3 to move upwards. This upward movement of the first U-shaped rod 3 moves the circular clamp 67 upwards, which in turn moves the chemical drum upwards, allowing it to be tilted. Simultaneously, the upward movement of the first U-shaped rod 3 moves the fixing block 61 upwards, which in turn moves the first gear 62 upwards. The first gear 62 meshes with the first rack 611 and rotates, causing the belt 63 to rotate. The belt 63 then rotates the second gear 64, which in turn rotates the third gear. The gear rotates at 65 degrees, causing the circular clamp 67 to rotate. The rotation of the circular clamp 67 causes the chemical drum to flip, allowing the raw materials in the chemical drum to be poured out. This reduces the uncertainty and labor intensity of manual operation, improves work efficiency, and lowers labor costs. At the same time, the U-shaped rod 3 moves upward, causing the extrusion rod 610 to move upward. The extrusion rod 610 moves upward, causing the long rod 69 to move closer to the circular clamp 67. The long rod 69 moves closer to the circular clamp 67, causing the limiting rod 68 to move closer to the circular clamp 67. The limiting rod 68 moves closer to the circular clamp 67 to limit the angle of the chemical drum, preventing the chemical drum from over-tilting, preventing the chemical raw materials from spilling, causing raw material waste, and increasing production costs.

[0024] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a fixing device and a deceleration device; the fixing device includes a sliding rod 76, an L-shaped clamping rod 77, a first clamping plate 78 and a second clamping plate 79. The sliding rod 76 is slidably installed on the outer wall of the circular clamp 67, the L-shaped clamping rod 77 is fixedly installed on the side of the sliding rod 76 near the circular clamp 67, the first clamping plate 78 is fixedly installed on the side of the sliding rod 76 near the sliding plate 5, and the second clamping plate 79 is fixedly installed on the outer wall of the circular clamp 67. The sliding rod 76 and the L-shaped clamping rod 77 limit and clamp the chemical drum, preventing the chemical drum from slipping and loosening during the tilting process, causing chemical raw materials to splash and injure workers, and causing waste of raw materials.

[0025] The fixing device also includes a second rack 71, an L-shaped rack 72, a rotating shaft 73, a fourth gear 74, and a reset block 75. The second rack 71 is fixedly installed on the side of the limiting rod 68 near the circular clamp 67. The L-shaped rack 72 is slidably installed on the inner wall of the sliding plate 5. The rotating shaft 73 is fixedly installed on the inner wall of the sliding plate 5. The fourth gear 74 is rotatably installed on the circumferential surface of the rotating shaft 73. The reset block 75 is fixedly installed on the side of the L-shaped rack 72 near the sliding rod 76. The second rack 71 meshes with the fourth gear 74, and the L-shaped rack 72 meshes with the fourth gear 74. The second rack 71, the L-shaped rack 72, and the fourth gear 74 limit and release the sliding rod 76, saving manpower and improving work efficiency.

[0026] A first spring is provided between the first clamping plate 78 and the second clamping plate 79. The side of the sliding rod 76 away from the circular clamp 67 is a first inclined surface, which facilitates the reset of the sliding rod 76 and the squeezing of the sliding rod 76.

[0027] The deceleration device includes a second U-shaped rod 81, a cylinder 82, a disc 83, a vertical rod 84, a contact rod 85, a spring 86, and an arc-shaped block 87. The second U-shaped rod 81 is fixedly installed on the top of the first U-shaped rod 3, the cylinder 82 is fixedly installed on the bottom of the second U-shaped rod 81, the disc 83 is slidably installed on the inner wall of the cylinder 82, the vertical rod 84 is fixedly installed on the top of the disc 83, the contact rod 85 is fixedly installed on the bottom of the vertical rod 84, the spring 86 is fixedly installed on the top of the disc 83, and the arc-shaped block 87 is fixedly installed on the inner wall of the cylinder 82. It decelerates the overturning of the chemical drum to prevent the chemical drum from overturning too quickly, which could cause raw materials to splash out of the drum opening, injuring workers and wasting raw materials. At the same time, the vibration makes the raw materials in the chemical drum more cleanly poured out.

[0028] The cylinder 82 has an exhaust port on its top, and the side of the spring 86 near the arc block 87 is an arc surface, which facilitates the up and down movement of the spring 86 to generate vibration.

[0029] In this embodiment, during operation: the limiting rod 68 moves towards the circular clamp 67, causing the second rack 71 to move towards the circular clamp 67. The movement of the second rack 71 towards the circular clamp 67 causes the fourth gear 74 to rotate. The rotation of the fourth gear 74 causes the L-shaped rack 72 to move away from the circular clamp 67. The movement of the L-shaped rack 72 away from the circular clamp 67 causes the reset block 75 to move. The reset block 75 moves and disengages from the sliding rod 76. After disengaging from the reset block 75, the sliding rod 76 moves downwards due to the elasticity of the first spring. The downward movement of the sliding rod 76 causes the L-shaped locking rod 77 to move downwards, limiting and locking the chemical drum to prevent it from slipping and loosening during pouring, thus preventing chemical spillage that could injure workers, waste materials, and increase costs. Simultaneously, after the pouring is completed, the hydraulic... Cylinder 2 drives the first U-shaped rod 3 to move downwards. The downward movement of the first U-shaped rod 3 drives the extrusion rod 610 to move downwards. The downward movement of the extrusion rod 610 drives the limiting rod 68 to move away from the circular clamp 67. The movement of the limiting rod 68 away from the circular clamp 67 drives the second rack 71 to move. The movement of the second rack 71 drives the fourth gear 74 to rotate. The rotation of the fourth gear 74 drives the L-shaped rack 72 to move closer to the circular clamp 67. The movement of the L-shaped rack 72 closer to the circular clamp 67 drives the reset block 75 to move. The reset block 75 moves and contacts the sliding rod 76, squeezing the sliding rod 76. The sliding rod 76 moves upwards under the squeezing force. The upward movement of the sliding rod 76 drives the L-shaped locking rod 77 to move upwards. The upward movement of the L-shaped locking rod 77 releases the limit on the chemical drum, making it convenient to remove the chemical drum after the material is poured, saving manpower and improving work efficiency.

[0030] When the chemical drum is tilted to empty, the sliding rod 76 contacts and squeezes the contact rod 85. The contact rod 85 moves upward under the squeezing force, which drives the vertical rod 84 to move upward. The vertical rod 84 then drives the disc 83 to move upward, slowing down the tilting of the chemical drum and preventing the raw materials from splashing out of the drum opening too quickly, which could injure workers and waste materials. At the same time, the upward movement of the disc 83 drives the spring 86 to move upward. The spring 86 then contacts the arc block 87, causing the vertical rod 84 to vibrate. The vibration of the vertical rod 84 drives the circular clamp 67 to vibrate, making the raw materials in the chemical drum empty more cleanly, increasing the unloading speed, reducing unloading time and residue, and improving production efficiency.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
