Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a mixed feeding system. Background Art

[0002] In the process of plastic production, it is first necessary to add materials in a preset proportion according to the formula into a mixing container to form a mixture, then stir it so that all the materials can be fully mixed, and finally put the mixture into a reactor for chemical reaction.

[0003] At present, the mixing amount of the existing mixing container is generally below 500kg. If the customer places a large-volume order, for example, an order for 5 tons of products, it is necessary to carry out multiple feeding and mixing, which is very labor-intensive and material-intensive. In order to solve the above-mentioned technical problems, the prior art, such as the "Automatic Continuous Feeding Device for Chitosan" with the publication number CN205132577U, provides a technical inspiration for realizing large-scale mixing. The technology includes a conveyor belt, a silo and a reactor. The conveyor belt is tilted, and its bottom end is arranged above the silo. The bottom of the silo is connected to a spiral conveyor belt, and a number of discharge ports are arranged on the spiral conveyor belt, and a number of corresponding reactors are arranged below the discharge port. Workers can add materials of a preset proportion in the silo according to the formula in advance to form a mixture, and then set a stirring device in the silo to mix the raw materials, and finally transport the mixed raw materials to the reactor through a spiral conveyor belt.

[0004] However, the above-mentioned feeding system still has the following defects: Generally speaking, when customers place large-volume orders, the products they require are not of the same chemical composition, but the base materials are the same, so different additives need to be added after the initial mixing, and the above-mentioned feeding system cannot perform secondary mixing, which lacks practicality. Utility Model Content

[0005] The utility model aims to provide a mixing feeding system which can realize large batches and has secondary mixing.

[0006] According to the first embodiment of the present invention, the mixed feeding system comprises:

[0007] A silo, wherein a stirring mechanism is provided therein, wherein the silo is provided with a first feed inlet and a first discharge outlet in sequence from top to bottom, wherein the first discharge outlet is connected to a first discharge channel with a switch valve;

[0008] A feeder, which is provided with a feeding mechanism, a second feeding port and a second discharging port, wherein the feeding mechanism has a feeding direction from the second feeding port to the second discharging port, and the second discharging port is connected to a second discharging channel;

[0009] A feeding cart having a storage chamber, wherein the feeding cart is provided with an inlet and an outlet in sequence from top to bottom, the inlet of the feeding cart is connected with a three-way pipe, the first discharge channel and the second discharge channel are respectively detachably connected to the three-way pipe, the outlet of the feeding cart is provided with a gate, and the bottom of the feeding cart is connected with a roller;

[0010] The feed port of the reactor is fixedly arranged on the floor slab.

[0011] The mixed feeding system according to the embodiment of the utility model has at least the following beneficial effects: workers add a large amount of materials into the silo from the first feed port according to the formula ratio, and the mixture in the silo forms a base material under the stirring of the stirring mechanism. When a certain type of plastic product needs to be produced, the first discharge channel and the second discharge channel are first connected to the three-way pipe, and the outlet of the feeding vehicle is closed. The feeder is started while the switch valve is opened, and the base material in the silo continuously falls into the storage chamber of the feeding vehicle through the three-way pipe. On the other hand, the feeder also continuously transports additives to the three-way pipe. Since the flow rate of the base material and the flow rate of the additive are both controllable, the base material and the additive are controlled. The agent can be mixed in the three-way pipe according to the formula ratio. After the feeding cart is loaded with a preset weight of raw materials, the switch valve is closed, the feeder is stopped, and the first discharge channel and the second discharge channel are removed from the three-way pipe. Then the feeding cart is pushed to the designated feeding port of the reactor. Finally, the gate of the feeding cart is opened to feed the raw materials in the feeding cart into the reactor. Compared with the prior art, the utility model can meet the large-scale mixing of substrates and the secondary mixing of substrates and additives. Since the feeding cart is mobile, it can meet the feeding needs of different reactors, thereby producing plastics with different components. The efficiency can also be improved by setting up multiple feeding carts, and the practicality is extremely strong.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] like Figure 1 and Figure 2As shown, according to the mixed feeding system of the first embodiment of the utility model, it includes a silo 100, a feeder 200, a feeding vehicle 300 and a reactor (not shown in the drawings). In order to facilitate the operation of workers, the mixed feeding system can be arranged in a three-dimensional manner, wherein the reactor is arranged on the first floor of the factory building, and its reactor feeding port 400 upwardly penetrates the floor slab of the second floor and is fixedly arranged on the floor slab of the second floor, and the height of the reactor feeding port 400 from the floor should not exceed 50cm. The silo 100 is installed on the third floor, and a stirring mechanism 110 is arranged therein. The silo 100 is provided with a first feed port 120 and a first discharge port in sequence from top to bottom, and the first feed port 120 is connected to a feed channel 121, and the feed channel 121 upwardly penetrates the floor slab of the fourth floor and is fixedly arranged on the floor slab of the fourth floor, so as to facilitate workers to load materials, and the first discharge port is connected to a first discharge channel 131, and the first discharge channel 131 penetrates the floor slab of the third floor and extends downward to the second floor.

[0032] Specifically, the first discharge channel 131 is provided with a switch valve 140, the switch valve 140 includes a gate housing 141, a gate, and a telescopic device 142 fixedly connected to the gate, the gate housing 141 is communicated with the first discharge channel 131, the gate is located in the gate housing 141, and the telescopic device 142 includes any one of an electric push rod, a cylinder or a hydraulic cylinder. In this embodiment, the telescopic device 142 can be selected as a cylinder. When the telescopic device 142 is extended, the gate closes the first discharge channel 131, and when the telescopic device 142 is retracted, the gate no longer closes the first discharge channel 131, and the flow rate of the first discharge channel 131 can be set according to the telescopic length of the telescopic device 142.

[0033] Furthermore, in order to improve the fluidity of the substrate in the silo 100, a vibrating bucket 150 is elastically connected to the lower end of the silo 100, and the vibrating bucket 150 is connected to a vibration motor 151, and the lower end of the vibrating bucket 150 is flexibly connected to the first discharge channel 131. When the vibration motor 151 is started, the vibrating bucket 150 vibrates in all directions under the action of the vibration motor 151, thereby accelerating the flow of the substrate. Since the position of the vibrating bucket 150 is changeable, the vibrating bucket 150 is flexibly connected to the lower end of the silo 100 through a soft connection 152, and the vibrating bucket 150 is flexibly connected to the first discharge channel 131 through a soft connection 152.

[0034] It should be noted that, in order to cope with different production orders, the number of reactors is generally more than one. No matter how many reactors are set, the reactor feeding port 400 is fixedly set on the second floor slab. Since the construction cost of the silo 100 is relatively high, for most manufacturers, only one silo 100 is needed to meet daily production needs. Since the number of silos 100 is less than the number of reactors, the feeding vehicle 300 needs to be set to transport the raw materials.

[0035] In addition, the feeder 200 and the feeding vehicle 300 are both arranged on the second floor. The feeding vehicle 300 has a roller 330 and can be moved arbitrarily. The feeder 200 is arranged below the first discharge channel 131. Specifically, the feeder 200 includes a reduction motor 210, a transversely arranged feed pipe 220 and a long rotating shaft 230 with spiral blades 231. The long rotating shaft 230 is arranged in the feed pipe 220. The reduction motor 210 is arranged outside the feed pipe 220 and drives the long rotating shaft 230 to rotate. At this time, the reduction motor 210 and the long rotating shaft 230 together constitute a feeding mechanism. A second feed port is arranged at the top of the head end of the feed pipe 220. The second feed port is connected to a hopper 241. The hopper 241 is provided with a valve plate that can be opened or closed (not shown in the drawings). A second discharge port is arranged at the end of the feed pipe 220. The second discharge port is connected to a second discharge channel 251. The hopper 241 is used for temporarily storing additives. When the valve plate on the hopper 241 is opened, the additives in the hopper 241 can enter the interior of the conveying pipeline 220 from the second feed port. At this time, the reduction motor 210 is started, and the reduction motor 210 drives the long rotating shaft 230 to rotate. The spiral blades 231 on the long rotating shaft 230 can push the additives to the second discharge port for transportation.

[0036] Furthermore, in order to control the output flow of the first discharge channel 131 and the second discharge channel 251, the first discharge channel 131 is provided with a first flow sensor (not shown in the drawings), and the second discharge channel 251 is provided with a second flow sensor (not shown in the drawings), the first flow sensor is electrically connected to the telescopic device 142, and the second flow sensor is electrically connected to the reduction motor 210. In this embodiment, the first flow sensor and the second flow sensor can be selected as powder flow meters, which can be connected to the discharge channel. The powder flow meter adopts electrostatic measurement technology. When the powder in the discharge channel passes through a fixed sensor, the weak current generated by the powder particles in motion is collected by the sensor and transmitted to the transmitter, which is filtered, amplified, and processed into a standard output value that is linearly related to the powder flow. Since the telescopic device 142 and the reduction motor 210 are both electrically connected to a powder flow meter, the electrical signal detected by the powder flow meter can be fed back to the controller, and the controller drives the telescopic device 142 and the reduction motor 210 to adjust the operating parameters, so as to keep the powder flow rate of the first discharge channel 131 and the powder flow rate of the second discharge channel 251 near the preset value, so as to achieve the purpose of quantitative transportation.

[0037] It is understandable that the present invention does not limit the specific structures of the switch valve 140 and the feeding mechanism. In some other embodiments, the two may also adopt other different structures without being limited to the above embodiments.

[0038] In addition, the feeding cart 300 has a storage chamber with an inverted cone structure, and a switch door 310 is provided on the top of the feeding cart 300. The switch door 310 includes a fixed portion 311 and a movable portion 312. The fixed portion 311 is provided with an inlet, and the movable portion 312 is hinged to the fixed portion 311. The inlet can be connected to the storage chamber, and the feeding cart 300 is provided with an outlet at the lower end of the storage chamber, and the outlet is provided with a gate 320. The inlet is connected to a three-way pipe 500, and the three-way pipe 500 is provided with two connecting ends, and the two connecting ends are respectively used for detachable connection with the first discharge pipe and the second discharge pipe, so as to realize the assembly between the silo 100, the feeder 200 and the feeding cart 300.

[0039] With the above structure, workers can add a large amount of materials from the feed channel 121 to the silo 100 according to the formula ratio on the fourth floor, and the mixture in the silo 100 forms a base material under the stirring of the stirring mechanism 110. When a certain type of plastic product needs to be produced, the first discharge channel 131 and the second discharge channel 251 are first connected to the three-way pipe 500, and the outlet of the feeding vehicle 300 is closed. At the same time, a proper amount of additives are added to the hopper 241. The feeder 200 is started while the switch valve 140 is opened. The substrate in the silo 100 continuously falls into the storage chamber of the feeding cart 300 through the three-way pipe 500. On the other hand, the feeder 200 also continuously delivers additives to the three-way pipe 500. Since the flow rate of the substrate and the flow rate of the additive are both controllable, the substrate and the additive can be mixed in the three-way pipe 500 according to the formula ratio. After the feeding cart 300 is loaded with a preset weight of raw materials, the switch valve 140 is closed, the feeder 200 is stopped, and the first discharge channel 131 and the second discharge channel 251 are removed from the three-way pipe 500. Then, the feeding cart 300 is pushed to the designated reactor feeding port 400, and finally, the gate 320 of the feeding cart 300 is opened to feed the raw materials in the feeding cart 300 into the reactor. Compared with the prior art, the utility model can meet the needs of large-scale mixing of substrates and secondary mixing of substrates and additives. Since the feeding cart 300 is mobile, it can meet the feeding needs of different reactors, thereby producing plastics with different components. The efficiency can also be improved by setting up multiple feeding carts 300, and the utility model is extremely practical.

[0040] It is understandable that, in addition to being able to load raw materials from the silo 100, the feeding cart 300 can also open the movable portion 312 to expose a larger opening 301 so that workers can manually feed materials. After that, the worker places a portable blender in the storage chamber to mix the materials in the storage chamber. This method is suitable for small batch production. In order to improve the safety factor of the feeding cart 300, the feeding cart 300 is provided with a support portion (not shown in the drawings), which can be a support rod. The side of the movable portion 312 is provided with a hole. When the movable portion 312 is opened, the worker can rotate the support rod to insert it into the hole of the movable portion 312, thereby limiting the position of the movable portion 312 to prevent it from falling and injuring people.

[0041] like Figure 3As shown, in order to facilitate the quick docking of the first discharge channel 131 and the second discharge channel 251 with the three-way pipe 500, the first discharge channel 131 has a first flexible segment 1311, and the second discharge channel 251 has a second flexible segment 2511. In this embodiment, the first flexible segment 1311 and the second flexible segment 2511 can both be selected as bellows, and a first quick-release structure is provided at the end of the first discharge channel 131, and a second quick-release structure 2512 is provided at the end of the second discharge channel 251. Correspondingly, the two connecting ends of the three-way pipe 500 are provided with a third quick-release structure 510. In this embodiment, the first quick-release structure, the second quick-release structure 2512 and the third quick-release structure 510 can all be equipped with chuck joints. When the first discharge channel 131 needs to be connected to the three-way pipe 500, the chuck joints of the two are first aligned, and then the two chuck joints are wrapped with a clamp 600, and finally the bolt 610 on the clamp 600 is tightened so that the clamp 600 can bite the two chuck joints. This operation method is also applicable to the connection between the second discharge channel 251 and the three-way pipe 500. When disassembling, it is only necessary to loosen the bolt 610 on the clamp 600 and remove the clamp 600 to complete the separation of the two chuck joints. However, the utility model does not specifically limit the above-mentioned quick-release structure. As long as it can meet the rapid assembly and disassembly between the two pipes, no matter what structure the quick-release structure is, it belongs to the protection scope of the utility model.

[0042] In some embodiments of the utility model, the fixed part 311 of the feeding cart 300 is provided with an air leakage hole (not shown in the drawings), and a filter is connected to the air leakage hole. The air leakage hole is used to discharge the air in the storage room, and the filter is used to isolate the raw materials from spilling out.

[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
