Abstract
Description
Technical Field
[0001] This utility model relates to the field of pellet core liquid supply, and in particular to a pellet dropping device. Background Technology
[0002] The feeding system of the pelleting equipment is an essential system in the pelleting process. Common core liquid feeding systems use a single dropper head equipped with a single core liquid pump pipeline for continuous feeding, typically operating for extended periods. However, if solids are present in the core liquid, the narrow rotor gap can lead to solid accumulation over time, causing blockages, inaccurate metering, or intermittent feeding that affects final product quality. Therefore, it is necessary to stop the machine, disassemble the pump, soak and clean it to ensure unobstructed flow, potentially shortening the production cycle and resulting in lower production efficiency and higher costs. Utility Model Content
[0003] The purpose of this invention is to provide a pelletizing equipment that can effectively solve the problems of shortened production cycle, low production efficiency, and high production cost caused by the need to stop and clean existing core liquid pumps when they malfunction.
[0004] The purpose of this utility model is achieved as follows: a pellet-making device includes a core liquid storage tank, at least one dropper, at least one core liquid supply pipeline, and at least one adhesive supply pipeline. The dropper is responsively connected to the corresponding core liquid supply pipeline and the corresponding adhesive supply pipeline. The core liquid supply pipeline is provided with spaced inlet and outlet adapters. At least two sets of pumping components are connected in parallel between the inlet and outlet adapters. Each set of pumping components includes a core liquid pump, which is responsively connected to the inlet and outlet adapters through inlet branch pipes and outlet branch pipes, respectively.
[0005] In a preferred embodiment of this utility model, an inlet switch valve is provided on the inlet branch pipe, and an outlet switch valve is provided on the outlet branch pipe.
[0006] In a preferred embodiment of this utility model, both the inlet switch valve and the outlet switch valve are manual switch valves.
[0007] In a preferred embodiment of the present invention, the core liquid supply pipeline includes a first supply pipeline and a second supply pipeline. The two ends of the first supply pipeline are respectively connected to the core liquid storage tank and the inlet adapter, and the two ends of the second supply pipeline are respectively connected to the outlet adapter and the corresponding dripper.
[0008] In a preferred embodiment of the present invention, the feed adapter has a main inlet interface and at least two branch inlet interfaces. The main inlet interface is connected to the first feed pipeline, and the branch inlet interfaces are connected to the corresponding branch inlet pipes. The discharge adapter has a main outlet interface and at least two branch outlet interfaces. The main outlet interface is connected to the second feed pipeline, and the branch outlet interfaces are connected to the corresponding branch outlet pipes.
[0009] In a preferred embodiment of this utility model, two sets of pumping components are provided between the feed adapter and the discharge adapter.
[0010] In a preferred embodiment of this utility model, the core liquid pump is a gear pump.
[0011] In a preferred embodiment of the present invention, the bottom of the core liquid storage tank is concave to form an arc-shaped groove with a high center and low periphery, and one end of the core liquid supply pipeline extends into the core liquid storage tank and is arranged close to the bottom side wall of the core liquid storage tank.
[0012] In a preferred embodiment of this utility model, a cleaning pipeline is connected to the core liquid supply pipeline in a way that allows for both on- and off-off operation.
[0013] In a preferred embodiment of this utility model, the core liquid storage tank, dripper, core liquid supply pipeline, adhesive supply pipeline, feed adapter, discharge adapter, core liquid pump, inlet branch pipe and outlet branch pipe are all made of food-grade material.
[0014] As described above, the pelletizing equipment of this utility model, by setting at least two sets of pumping components on the core liquid supply pipeline, only requires the operation of a portion of the core liquid pumps during use. When an abnormality such as blockage occurs in the already activated core liquid pump, it can be switched to other core liquid pumps. Then, the abnormal core liquid pump can be cleaned accordingly. Compared with the existing method where each dropper corresponds to only one core liquid pump, and when an abnormality such as blockage occurs in the core liquid pump, the machine needs to be stopped, the pump disassembled and cleaned before it can be restarted, the structure of this application greatly extends the production time and cycle, greatly improves production efficiency, and reduces production costs.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0026] like Figures 1 to 3 As shown, this application provides a pellet-making device, including a core liquid storage tank 1, at least one dropper 2, at least one core liquid supply pipeline 3, and at least one adhesive supply pipeline 4. The dropper 2 is connected to the corresponding core liquid supply pipeline 3 and the corresponding adhesive supply pipeline 4 in a way that can be switched on and off. The core liquid supply pipeline 3 is provided with spaced inlet adapters 32 and outlet adapters 34. At least two sets of pumping components 33 are connected in parallel between the inlet adapters 32 and the outlet adapters 34. Each set of pumping components 33 includes a core liquid pump 332. The core liquid pump 332 is connected to the inlet adapter 32 and the outlet adapter 34 in a way that can be switched on and off through an inlet branch pipe 331 and an outlet branch pipe 333, respectively.
[0027] The system includes one core liquid storage tank 1, and the same number of drippers 2, core liquid supply pipelines 3, and adhesive supply pipelines 4, which can all be one or at least two. Each pumping assembly 33 includes one core liquid pump 332. The core liquid storage tank 1 is used to store the prepared core material; the dripper 2 has an existing structure and is used for pellet forming. The pellets 5 formed during operation are as follows: Figure 1 As shown; the core liquid supply pipeline 3 is used to connect the core liquid storage tank 1 and the dripper 2 for conveying the core liquid; the adhesive liquid supply pipeline 4 is used to connect the dripper 2 and the corresponding adhesive liquid storage tank for conveying the adhesive liquid required for pellet forming. Each dripper 2 is equipped with at least two core liquid pumps 332 to provide continuous power for core liquid supply.
[0028] During use, for the same dripper 2, only a portion of the core liquid pumps 332 are turned on (that is, only a portion of the pumping components 33 are connected to the feed adapter 32 and the discharge adapter 34), while the remaining core liquid pumps 332 are in a stopped state. When solid matter in the core liquid causes core material to accumulate and stick, leading to blockage of the rotor channel of the core liquid pump 332, resulting in inaccurate metering, intermittent discharge, and affecting product quality, that is, when the turned-on core liquid pump 332 experiences blockage or other abnormalities, the core liquid pump 332 is turned off, and the inlet branch pipe 331 and outlet branch pipe 333 on both sides of the core liquid pump 332 are not connected to the feed adapter 32 and the discharge adapter 34, respectively. The supply is switched to other core liquid pumps 332, and the abnormal core liquid pump 332 is cleaned accordingly.
[0029] Therefore, the pellet-dripping equipment of this application, by setting at least two sets of pumping components 33 on the core liquid supply pipeline 3, only needs to be turned on a portion of the core liquid pumps 332 during use. When the turned-on core liquid pumps 332 are blocked or other abnormalities occur, the equipment can be switched to other core liquid pumps 332. Then, the core liquid pumps 332 with abnormalities can be cleaned accordingly. Compared with the existing method where each dripper 2 corresponds to only one core liquid pump 332, and when the core liquid pump 332 is blocked or other abnormalities occur, the machine needs to be stopped, the pump disassembled and cleaned before it can be turned on again, the structure of this application greatly extends the production time and cycle, greatly improves production efficiency, and reduces production costs.
[0030] In the specific implementation method, refer to Figure 2 An inlet switch valve 3311 is provided on the inlet branch pipe 331, and an outlet switch valve 3331 is provided on the outlet branch pipe 333. This facilitates the control of the on / off state of the core liquid pump 332 with the feed adapter 32 and the discharge adapter 34, thereby facilitating the switching of different core liquid pumps 332 so that each core liquid pump 332 can be used interchangeably during production. Generally, both the inlet switch valve 3311 and the outlet switch valve 3331 are manual switch valves, resulting in a simpler structure.
[0031] Optionally, the manual on / off valve can be made of stainless steel, specifically a food-grade stainless steel sanitary valve, which should be disassembled, soaked, cleaned, and disinfected periodically. During installation, the inlet switch valve 3311 should be placed as close as possible to the inlet adapter 32, and the outlet switch valve 3331 should be placed as close as possible to the outlet adapter 34 to avoid dead zones and the risk of secondary contamination.
[0032] It is understood that the aforementioned core liquid supply pipeline 3 is disconnected in the middle, with the inlet adapter 32 and outlet adapter 34 connected at the disconnection point. For details, please refer to... Figure 1The core liquid supply pipeline 3 includes a first supply pipeline 31 and a second supply pipeline 35. The two ends of the first supply pipeline 31 are connected to the core liquid storage tank 1 and the feed adapter 32, respectively. The two ends of the second supply pipeline 35 are connected to the discharge adapter 34 and the corresponding dripper 2, respectively.
[0033] The adapter is a box-like structure with an internal cavity, featuring a main interface on one side and multiple branch interfaces on the other. (See reference...) Figure 1 and Figure 2 The feed adapter 32 has a main inlet and at least two branch inlet interfaces. The main inlet is connected to the first feed line 31, and the branch inlet interfaces are connected to corresponding branch inlet pipes 331. The discharge adapter 34 has a main outlet and at least two branch outlet interfaces. The main outlet is connected to the second feed line 35, and the branch outlet interfaces are connected to corresponding branch outlet pipes 333. The branch inlet pipes 331 and the branch outlet pipes can be, for example, PU tubing. Specifically, the number of branch inlet interfaces in the feed adapter 32 and the number of branch outlet interfaces in the discharge adapter 34 are the same as the number of pumping components 33 corresponding to each dripper 2.
[0034] The specific number of pumping components 33 corresponding to each dripper 2 can be determined according to actual needs. For example, in a specific embodiment, two sets of pumping components 33 are provided between the feed adapter 32 and the discharge adapter 34. Accordingly, each dripper 2 is equipped with two core liquid pumps 332. The feed adapter 32 forms a two-into-one adapter and is connected to the first supply pipeline 31 and two inlet branch pipes 331; the discharge adapter 34 forms a two-in-one adapter and is connected to the two outlet branch pipes 333 and the second supply pipeline 35. Each dripper 2 is equipped with four manual switching valves for switching the two core liquid pumps 332 equipped in each dripper 2.
[0035] During production, the two core liquid pumps 332 on the core liquid supply line 3 are operated in a staggered manner, ensuring that the inlet switch valve 3311 and outlet switch valve 3331 of one line are open, while the inlet switch valve 3311 and outlet switch valve 3331 of the other line are closed. One core liquid pump 332 is in operation to supply material to the dripper 2. Based on the material properties and the actual working stability of the supply, if continuous abnormalities occur, the other core liquid pump 332 is switched on in a timely manner. During the switching process, after stopping one core liquid pump 332, the pellet dropping stops, and then the other core liquid pump 332 is switched on to start production according to the dripper 2 start-up process. The entire switching process is very fast and can be considered as a non-stop switching.
[0036] In this embodiment, a two-way conveying system is adopted. When one of the conveying systems experiences inaccurate metering or intermittent discharge, the system is switched. The inlet and outlet must be closed immediately (i.e., the inlet switch valve 3311 and outlet switch valve 3331 on that system) and the core liquid pump 332 must be disassembled and stopped. Then, the pump and pipeline are soaked and cleaned. After disinfecting the pump and pipeline according to the production time and cycle, the system can be switched back to use. This greatly extends the production time and cycle, significantly improves production efficiency, and reduces production costs.
[0037] Alternatively, the core liquid pump 332 can be a gear pump. Using a gear pump for precise, small-dose feeding improves feeding accuracy; disassembly and soaking cleaning are required after each production cycle to ensure accurate metering. The core liquid must be filtered through a ≤40-mesh filter before being stored in the core liquid storage tank 1 to prevent large particles from damaging the gears of the core liquid pump 332.
[0038] Further optional, see Figure 3 The bottom of the core liquid storage tank 1 is concave, forming an arc-shaped groove 11 with a high center and low periphery. One end of the core liquid supply pipe 1 extends into the core liquid storage tank 1 and is arranged close to the bottom side wall of the core liquid storage tank 1. The core liquid storage tank 1 is vertically installed and is generally a cylindrical tank. The arc-shaped groove 11 is a conical groove with a gradually decreasing diameter, so that the bottom surface of the core liquid storage tank 1 is high at the center and low around the periphery. One end of the core liquid supply pipe 1 is located at the bottom of the core liquid storage tank 1 and close to the lower periphery, so that the core liquid storage tank 1 can deliver the core liquid to the maximum extent through the core liquid supply pipe 3.
[0039] Alternatively, a cleaning line can be connected to the core liquid supply line 3 in a way that allows for switching on and off.
[0040] Taking two core liquid pumps 332 corresponding to each dripper 2 as an example, when one core liquid pump 332 malfunctions and switches to the other, the malfunctioning pump 332 can be directly disassembled and cleaned; alternatively, after the production cycle is completed, all four switching valves corresponding to the dripper 2 can be opened, and the two core liquid pumps 332 can be cleaned online using the cleaning pipeline. Of course, for thorough cleaning, disassembly and cleaning of the pumps are generally required. The specific operation depends on the actual needs.
[0041] Furthermore, the core liquid storage tank 1, dripper 2, core liquid supply pipeline 3, adhesive supply pipeline 4, feed adapter 32, discharge adapter 34, core liquid pump 332, inlet branch pipe 331 and outlet branch pipe 333 are all made of food-grade materials.
[0042] Furthermore, the following compares the existing core liquid supply pipeline 3 between the dripper 2 and the core liquid storage tank 1, which has only one core liquid pump 332, with two parallel core liquid pumps 332 in a specific embodiment of this application. The relevant production cycle data are as follows:
[0043] Production process Single-core liquid pump Dual-core liquid pump Production cycle hr 30 60 Production cleaning and disinfection cost per kg of pellets 0.24 0.12 Production efficiency: kg pellets / hr 2.7 3.0
[0044] As can be seen from the table above, the pelletizing equipment described in this application can effectively improve production efficiency and reduce production costs.
[0045] In summary, the pelletizing equipment of this application is a high-efficiency pelletizing device. The prepared core liquid, stored in the core liquid storage tank 1, is transported to the pelletizing head 2 via a core liquid pump 332 operating in the core liquid supply pipeline 1 for pelletizing. Whenever pelletizing fails to meet standards, the operating core liquid pump 332 switches to another core liquid pump 332 to continue supplying core material. During production, the core liquid pump 332 can be switched almost without stopping, enabling long-term continuous supply of core liquid, thereby significantly improving production efficiency and reducing production costs. This solves the problems of current equipment where solid matter in the core liquid causes core material accumulation and adhesion, leading to blockage of the core liquid pump 332 rotor channel, resulting in inaccurate metering, intermittent discharge affecting product quality, requiring shutdown for cleaning, potentially shortening the production cycle, and causing low production efficiency and high production costs.
[0046] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
