Description

Technical Field

[0001] This application relates to the field of sodium silicate processing equipment technology, and in particular to an automated bag-opening alkali-dissolving equipment. Background Technology

[0002] In the production and processing of sodium silicate, it is usually necessary to open the bagged solid raw material and put it into the alkali-dissolving tank to react with the liquid. The current practice mainly relies on manual operation, that is, the operator manually moves the raw material bag, uses a knife or semi-automatic equipment to cut open the packaging, and then pours or vibrates the material into the alkali-dissolving tank.

[0003] This traditional operating mode has many drawbacks: First, its production efficiency is low. The processes of opening, cleaning, and disposing of waste bags are cumbersome and cannot form a continuous production flow, becoming a bottleneck restricting overall production capacity. Second, direct contact between manual and corrosive chemical raw materials poses significant safety and health hazards, and the shaking and cleaning process easily generates dust, seriously polluting the working environment and endangering the respiratory health of operators. Furthermore, manual operation makes it difficult to ensure that materials are completely separated from the packaging bags, often leading to material residue and waste. At the same time, high labor costs and heavy physical burdens also restrict further improvement in production efficiency. Utility Model Content

[0004] To address this problem, this application provides an automated bag-opening alkali-dissolving device.

[0005] This application provides an automated bag-opening alkali-dissolving device, employing the following technical solution: a feeding hopper; a first tank body, the first tank body having a first cavity inside, the first cavity being connected to the discharge port of the feeding hopper; a cutting assembly, the cutting assembly being disposed within the first cavity; a second tank body, the second tank body being connected to the first tank body, the connection between the second tank body and the first tank body having an opening, the second tank body having a second cavity inside, the bottom of the second cavity forming a liquid storage tank; a discharge roller, the discharge roller being rotatably disposed within the second cavity, the discharge roller being located directly above the liquid storage tank, the inlet at one axial end of the discharge roller being connected to the first cavity through the opening, the outlet at one axial end of the discharge roller being connected to the outside, and the discharge hole on the cylinder wall of the discharge roller being provided for material to fall.

[0006] Therefore, this utility model integrates a core structure consisting of a feeding hopper, a first trough, a cutting component, a second trough, and a discharge roller to construct a complete automated bag-opening and alkali-dissolving system. The feeding hopper is used for initial material reception, the first trough guides material transport, the cutting component breaks the bags, and the discharge roller, through its rotation and discharge port design, automatically separates the material from the packaging bag. The material then falls into the storage tank under its own weight for the alkali-dissolving reaction. Thus, through the synergistic effect of these structures, this equipment achieves fully automated and continuous operation from bag breaking to alkali dissolving and waste bag separation. This changes the traditional manual bag-opening and alkali-dissolving operation mode, significantly improving efficiency, ensuring safety, and reducing costs.

[0009] Optionally, at least two push plates are provided, and the at least two push plates are arranged along the axial direction and / or circumferential direction of the stripping drum.

[0010] Optionally, a spray pipe is also included, which is set on one side of the discharge port at one axial end of the dewatering drum; a funnel pipe is set between the feed inlet and the opening at one axial end of the dewatering drum, the funnel pipe is L-shaped in general, the feed inlet of the funnel pipe is connected to the opening, and the discharge port of the funnel pipe is connected to the discharge port at one axial end of the dewatering drum.

[0012] Optionally, a rotating support assembly is provided between the outer surface of the stripping roller and the second cavity. At least two sets of rotating support assemblies are provided along the axial direction of the stripping roller. Each set of rotating support assemblies includes two support rollers and an annular flange. The two support rollers are spaced apart, and the annular flange is provided on the circumferential surface of the stripping roller and rests on the two support rollers.

[0013] Optionally, the cutting assembly includes two cutter rollers and a drive motor. The two cutter rollers are arranged in parallel within the first cavity, and the drive motor is connected to the two cutter rollers in a transmission connection.

[0014] Optionally, a storage tank may also be included, with the storage tank connected to the storage tank via a pipe.

[0015] Optionally, a conveyor belt is also included, which is set between the feeding hopper and the first trough. The discharge port of the feeding hopper is set in correspondence with the conveyor belt, and the inlet of the first trough is set in correspondence with the conveyor belt.

[0016] In summary, this application has the following beneficial effects: By integrating the core structure of the feeding hopper, the first tank, the cutting component, the second tank, and the unloading roller, a complete automated bag-opening alkali-dissolving system is constructed. The feeding hopper is used for initial material reception, the first tank guides material transport, the cutting component breaks the bags, and the unloading roller, through its rotational motion and the structure of the discharge hole, automatically separates the material from the packaging bag.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This application discloses an automated bag-opening and alkali-dissolving device; see [link to relevant documentation]. Figure 1-3 This embodiment relates to an automated bag-opening alkali-dissolving equipment, including: a feeding hopper 3, a first tank 2, a cutting assembly, a second tank 4, and a discharge roller 6, etc.

[0021] The equipment includes a feeding hopper 3 located at the starting end for receiving bagged raw materials, with an inlet and an outlet; a first cavity inside the first trough 2, which communicates with the outlet of the feeding hopper 3 to guide the bagged raw materials; a cutting assembly located within the first cavity for cutting the bagged raw materials within it, capable of quickly piercing the packaging bags; and a second cavity inside the second trough 4, connected to the first trough 2, with an opening at the connection point to allow the second cavity inside the second trough 4 to communicate with the interior of the first trough 2. The first cavity is connected, and a liquid storage tank 5 is formed at the bottom of the second cavity for alkali treatment. The discharge roller 6 is set in the second cavity and is located directly above the liquid storage tank 5. Under the drive of external force, the discharge roller 6 can rotate in the second cavity. The feed port at one axial end of the discharge roller 6 is connected to the first cavity through an opening, and the discharge port at one axial end of the discharge roller 6 is connected to the outside. A discharge hole 61 is opened on the cylinder wall of the discharge roller 6. The diameter of the discharge hole 61 is larger than the size of the material, so that the bagged raw material in the discharge roller 6 can fall to the outside through the discharge hole 61.

[0022] Based on the above structure, during equipment operation, bagged raw materials are transported to the feed inlet of the hopper 3 via forklift or manual handling. The raw materials then enter the first cavity of the first tank 2 via the hopper 3, where they are quickly cut open by the internal cutting components. The broken bagged raw materials then enter the unloading roller 6 located in the second cavity of the second tank 4 through the opening at the connection between the first tank 2 and the second tank 4. The unloading roller 6 rotates continuously above the storage tank 5. The discharge hole 61 on its cylinder wall, with a diameter larger than the material size, allows the material inside the bag to fall into the storage tank 5 through the discharge hole 61 under the tumbling and agitation of the roller, undergoing the alkali-refining process. Simultaneously, because the size of the empty packaging bag is larger than the size of the discharge hole 61, it cannot pass through the discharge hole 61. Therefore, the separated empty packaging bags are discharged from the outlet at the other end of the axial direction of the unloading roller 6 as it rotates. This process is continuous and efficient, significantly reducing manual intervention and the risk of material exposure.

[0023] Therefore, this utility model integrates the core structure of the feeding hopper 3, the first trough 2, the cutting component, the second trough 4, and the unloading roller 6 to construct a complete automated bag-opening and alkali-dissolving system. The feeding hopper 3 is used to initially receive the material, the first trough 2 is used to guide the material conveying, the cutting component is responsible for breaking the bag, and the unloading roller 6, through its rotation and the setting structure of the discharge hole 61, automatically separates the material from the packaging bag. The material falls into the storage tank 5 under its own gravity to carry out the alkali-dissolving reaction. Therefore, through the synergistic effect of the above structures, this equipment realizes the fully automated and continuous operation from breaking the bag to the alkali-dissolving of the material and the separation of waste bags. This changes the traditional manual bag-opening and alkali-dissolving operation mode and has significant improvements in terms of efficiency, safety, and cost reduction.

[0024] The discharge holes 61 are provided in an array of at least two, which are arranged along the axial direction or circumferential direction of the discharge roller 6, or along both the axial direction and circumferential direction of the discharge roller 6. In this embodiment, there are thirty discharge holes 61, which are arranged along both the axial direction and circumferential direction of the discharge roller 6. That is, the discharge holes 61 are arranged in an array on the discharge roller 6, which makes it easier for the material to fall from the discharge holes 61 when it is swung by the discharge roller 6. This dense and uniformly distributed layout of discharge holes 61 greatly increases the material drop channel, ensuring that the material can be quickly and thoroughly separated from the discharge roller 6 and fall into the liquid storage tank 5, effectively avoiding the residue and accumulation of material in the roller.

[0025] Furthermore, a pusher plate 62 is provided on the inner wall of the unloading roller 6. The length direction of the pusher plate 62 is inclined relative to the axis of the unloading roller 6, that is, the length direction of the pusher plate 62 is not perpendicular to the axis of the unloading roller 6. This inclined arrangement is used to push the material inside the unloading roller 6 towards the discharge port at one axial end. It should be noted that the inclination direction of the pusher plate 62 can be set as needed. At the same time, different pushing directions of the pusher plate 62 can be achieved by setting different rotation directions of the unloading roller 6. It should also be noted that the material pushed towards the discharge port at one axial end of the unloading roller 6 can be raw material or packaging bags. The introduction of the pusher plate 62 gives the unloading roller 6 an axial conveying function, enabling it not only to separate materials, but also to actively push empty packaging bags towards the discharge port, ensuring the smoothness and continuity of the process.

[0026] The device includes at least two pusher plates 62, arranged either along the axial direction or the circumferential direction of the unloading roller 6, or along both the axial and circumferential directions of the unloading roller 6. In this embodiment, sixteen pusher plates 62 are arranged in an array on the unloading roller 6, making it easier for the packaging bags to be conveyed to the discharge port at one end of the axial direction when the unloading roller 6 is swung. The array arrangement of multiple pusher plates 62 forms a continuous and efficient spiral propulsion surface on the inner wall of the roller, which can generate a continuous and uniform thrust on the material, significantly improving the efficiency and reliability of empty packaging bag discharge and preventing the empty packaging bags from clogging or stagnating inside the roller.

[0027] This invention also includes a spray pipe 7, which is installed on one side of the discharge port at one axial end of the unloading drum 6. In use, by connecting an external water source, the spray pipe 7 can spray the discharge port at one axial end of the unloading drum 6, thereby preventing dust materials from being discharged through the discharge port when the unloading drum 6 rotates, thus avoiding pollution of the workshop. Furthermore, a funnel pipe 8 is installed between the inlet and the opening at one axial end of the unloading drum 6. The funnel pipe 8 is L-shaped and is used to adjust the vertical conveying direction to a horizontal conveying direction. The inlet of the funnel pipe 8 is connected to the opening, and the outlet of the funnel pipe 8 is connected to the discharge port at one axial end of the unloading drum 6. Thus, by installing the funnel pipe 8, the inlet at one axial end of the unloading drum 6 is relatively sealed, thereby preventing dust materials from being discharged through the inlet when the unloading drum 6 rotates, thus avoiding pollution of the workshop. Therefore, by simultaneously installing spray pipes 7 and funnel pipes 8 at both ends of the axial direction of the discharge drum 6, the material dust raised inside the discharge drum 6 can be effectively prevented from polluting the workshop, thus meeting the environmental protection requirements during equipment operation. The spray pipes 7 suppress dust through a water curtain, while the funnel pipes 8 prevent dust from escaping through a physical structure. Together, they form a comprehensive dust control system that addresses both the source and the path of dust pollution, greatly improving the working environment.

[0028] This invention also includes an exhaust fan 9 and a dust collection box 10. The exhaust fan 9 is connected to the second trough 4, its exhaust port is connected to the second cavity, and its exhaust outlet is connected to the inlet of the dust collection box 10. Thus, when the unloading drum 6 rotates, the exhaust fan 9 and the dust collection box 10 work together to reduce the amount of dust flying in the second cavity, further preventing dust from polluting the workshop. This negative pressure dust removal system, in conjunction with the aforementioned spraying and sealing measures, actively extracts and collects dust-laden air from the sealed cavity, purifies it through the dust collection box 10, and then discharges it, forming a third line of environmental protection, ensuring that the equipment operates efficiently while meeting strict workshop air quality standards.

[0029] A rotating support assembly is provided between the outer surface of the unloading drum 6 and the second cavity. At least two sets of rotating support assemblies are arranged along the axial direction of the unloading drum 6. In this embodiment, the two sets of rotating support assemblies are connected to both ends of the unloading drum 6. Further, each set of rotating support assemblies includes two support rollers 11 and an annular flange 12. The two support rollers 11 are spaced apart, and the annular flange 12 is disposed on the circumferential surface of the unloading drum 6, resting on the two support rollers 11. This achieves the rotating structure of the unloading drum 6. Subsequently, during use, the unloading drum 6 can be rotated within the second trough 4 simply by driving it with external force. This rotating support assembly structure is stable and reliable. Through multi-point support and limiting, it ensures that the unloading drum 6, especially under full load or uneven stress, can operate smoothly and with low noise for a long time, reducing vibration and wear, and improving the service life and stability of the equipment.

[0030] The cutting assembly includes two cutting rollers 13 and a drive motor. The two cutting rollers 13 are arranged parallel to each other in the first cavity, and the drive motor is connected to the two cutting rollers 13. Thus, by simply driving the two cutting rollers 13 to rotate, the bagged raw materials in the first cavity can be cut open, achieving the effect of automatic bag opening. The counter-rotating design of the double cutting rollers 13 creates a highly efficient shearing action, which can quickly and thoroughly cut through packaging bags of various materials, and is less prone to entanglement or jamming, laying a solid foundation for subsequent material separation processes.

[0031] This invention also includes a storage tank 14, with the storage tank 5 connected to it via a pipe. The liquid from the alkali-refining process is then pumped into the storage tank 14 for further processing. The storage tank 14 enables centralized storage and recycling of the alkali-refining solution, facilitating access for subsequent processes, managing solution composition, and controlling concentration, thus improving the standardization and operability of the entire alkali-refining process.

[0032] This invention also includes a conveyor belt 15, which is positioned between the feeding hopper 3 and the first trough 2. The discharge port of the feeding hopper 3 corresponds to the conveyor belt 15, and the inlet of the first trough 2 corresponds to the conveyor belt 15. Thus, by setting the conveyor belt 15, the specific and positional relationship between the feeding hopper 3 and the first trough 2 can be flexibly adjusted. In this embodiment, the conveyor belt 15 is inclined to lift bagged raw materials into the first trough 2. The introduction of the inclined conveyor belt 15 realizes automated lifting and conveying of materials from the ground to the processing station, further reducing the labor intensity of manual handling and making the overall layout of the equipment more flexible, adaptable to different workshop site conditions.
