[0064] In the description of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0065] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the reasons why it is difficult for the feeding device in the related technology to achieve stable quantitative and constant speed feeding of materials, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0066] In the related art, taking the use of a hopper feeder to feed materials as an example, the materials to be fed are directly placed in a storage bin. A discharge port that can be controlled to open and close is provided at the bottom of the storage bin. When materials need to be fed, the timing and size of the opening of the discharge port are controlled to adjust the timing, speed and amount of feeding.

[0067] In actual use, when this type of feeding equipment is used, the material in the storage bin is prone to arching, resulting in the inability to smoothly feed the material. In the existing structure, an arch-breaking mechanism is used to solve this problem. A disturbance mechanism is set in the storage bin near the storage port to stir the material to break the arch. Alternatively, a vibration mechanism is installed on the outer wall of the storage bin to break the arch through vibration, so that the material can be smoothly fed.

[0068] However, in some cases, the above methods are not applicable. For example, in the field of chemical production, most reaction processes require the use of catalysts. In chemical reactions, the timing of catalyst addition, the speed of addition, and the total amount need to be kept within the required range. Moreover, in most cases, the catalysts used are relatively active, and some are even flammable and explosive substances. Such materials should not be stirred or shaken during the addition process. Using existing types of feeding equipment, it is difficult to achieve stable quantitative and constant-speed feeding of materials.

[0069] To this end, the present application provides a feeding system to solve the technical problem in the prior art that it is difficult to achieve stable feeding of materials at a fixed quantity and speed.

[0070] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0071] To facilitate the description of the following embodiments, the present application takes the material being delivered as a quasi-cylindrical bar as an example for explanation, wherein quasi-cylindrical means that the overall shape of the material is approximately a cylindrical structure, but its cross-sectional shape may be an irregular circle, ellipse, or other approximate circular shape.

[0072] In the embodiment of the present application, a feeding system is provided, such as Figure 1 and Figure 2As shown, the feeding system includes a feeding box 1 and a feeding device 2. The feeding box 1 is used to store materials to be fed. A discharge port 11 is provided at the bottom of the feeding box 1. A feeding channel 12 and a plurality of separated storage rooms 13 are provided inside the feeding box 1.

[0073] Among them, the feeding channel 12 is inclined downward and connected to the discharge port 11, and the lower end opening of the feeding channel 12 is the feeding port 14. The material in the feeding channel 12 rolls downward along the feeding channel 12 and is then discharged through the feeding port 14; a plurality of storage rooms 13 are arranged along the extension direction of the feeding channel 12, and a connecting port is provided between each storage room 13 and the feeding channel 12, and each storage room 13 is inclined downward in a direction from away to close to the feeding channel 12, that is, when the material is placed in the storage room 13, it will roll downward under the action of its own weight and move into the feeding channel 12 through the connecting port.

[0074] In actual design, the sizes of the material storage room 13 and the feeding channel 12 are adjusted according to the specific sizes of the materials, so that the materials are arranged in a single row in the material storage room 13 and the feeding channel 12.

[0075] In addition, the feeding system further comprises a closing member 3 for closing and opening a plurality of communication ports.

[0076] The feeding device 2 is located between the feeding port 14 and the discharging port 11, receiving the material discharged from the feeding port 14 and transferring it to the discharging port 11, and the material is discharged from the discharging port 11 to realize the feeding of the material. During the material feeding process, the material feeding speed can be adjusted by adjusting the working speed of the feeding device 2.

[0077] When using the feeding system to feed materials, the materials are placed in the storage room 13. During the material feeding process, the closing piece 3 is adjusted so that multiple connecting ports are opened in sequence. The materials in each storage room 13 roll down into the feeding channel 12 in sequence. The materials in the feeding channel 12 are discharged through the feeding port 14 in sequence and transferred to the discharge port 11 by the feeding device 2.

[0078] This can avoid the phenomenon of arching that may occur during the feeding process due to a large amount of materials being piled up at the feeding port 14 and the discharging port 11, thereby ensuring the smooth feeding of materials. In addition, the separation of materials through the storage room 13 can reduce the risk of fire, explosion and other accidents when all materials are piled up in the same space, thereby improving safety.

[0079] Exemplary, reference Figure 3 and Figure 4 ,in, Figure 3 for Figure 2The back side schematic diagram is shown, and for ease of understanding, the invisible structure located inside the feeding box 1 in this view is represented by a lighter gray line to more conveniently represent the relative positional relationship of the various components.

[0080] The feeding device 2 includes a feeding roller 21 and a power member 22. The feeding roller 21 is rotatably connected to the feeding box 1. A gap is provided between the surface of the feeding roller 21 and the side wall of the feeding port 14. The size of the gap is smaller than the size of the material to be fed to prevent the material from falling through the gap. The surface of the feeding roller 21 is provided with a groove 211 for accommodating at least a part of the material. Here, accommodating at least a part of the material means that one of the materials is located in the groove 211, which can be completely in the groove 211, or partially in the groove 211 and partially outside the groove 211. The power member 22 is fixedly connected to the feeding box 1, and the output end is connected to the feeding roller 21 and drives the feeding roller 21 to rotate.

[0081] Exemplarily, the power member 22 is a rotary cylinder, which can conveniently drive the feeding roller 21 to rotate, driving the groove 211 to swing back and forth between the feeding port 14 and the discharge port 11. In other embodiments, the power member 22 can also be set as a motor to drive the feeding roller 21 to rotate. In the embodiment of the present application, the power member 22 is set as a rotary cylinder as an example.

[0082] In the initial state, the groove 211 is located at the lower side of the feeding port 14, and the material falls into the groove 211 through the feeding channel 12. Then, the power member 22 drives the feeding roller 21 to rotate, and drives the groove 211 to rotate to a state facing the discharge port 11, and the material falls from the groove 211 to the discharge port 11 to realize the feeding of the material. In the process of the feeding roller 21 driving the material transfer, the feeding roller 21 can also play the role of blocking the feeding port 14. As the feeding roller 21 rotates and returns to the initial state again, the subsequent material is fed.

[0083] refer to Figure 1 In order to facilitate the taking and placing of materials, the feeding box 1 includes a box body with an opening and a door panel arranged on the box body for closing the opening, and the box body and the door panel are arranged to form a closed space; the feeding channel 12 and the storage room 13 are located in the closed space, and the discharge port 11 is connected to the closed space, so that the material placed in the closed space is discharged through the discharge port 11.

[0084] For example, the first surface of the box body is set as an opening, and a door panel is installed at the opening to realize the opening and closing of the feeding box 1. The door panel can be hinged or slidably connected to the box body. The first surface is connected to multiple storage rooms 13 and the feeding channel 12 at the same time. In this way, in actual use, the convenience of placing materials in the storage room 13 is greatly improved.

[0085] In addition, when placing some materials, such as catalysts, it is necessary to ensure that the materials are stored in an inert gas environment, such as nitrogen, to prevent the catalyst from reacting with elements in the air, causing its catalytic effect to decrease or even fail. Figure 1 and Figure 2 The feeding box 1 is provided with an air inlet 15 for introducing protective gas into the enclosed space, and an exhaust port 16 for exhausting the gas in the enclosed space. The protective gas referred to here is an inert gas or other gas that will not react with the material or cause the material to deteriorate, such as nitrogen. The protective gas is introduced into the enclosed space through the air inlet 15, so that the original air therein is exhausted from the exhaust port 16, thereby replacing the internal air, so that the material is in an environment of protective gas, avoiding problems such as deterioration and performance degradation that may occur due to being in an air environment for a long time.

[0086] Exemplarily, the air inlet 15 is located at the lower side of the air outlet 16 , which is conducive to more convenient exhaustion of the original gas in the storage box 1 .

[0087] It should be noted that the formation of a closed space inside the feed box 1 does not mean that the inside of the feed box 1 is completely isolated from the outside world, but means that the material is stored in an environment relatively isolated from the outside world through the formed closed space, and air can be introduced into the space through the air inlet 15, and exhaust can be carried out through the exhaust port 16, so that the space for placing the material is filled with protective gas.

[0088] A drain port 17 is provided at the bottom of the feeding box 1, and the drain port 17 is connected to the feeding port 14. Taking the addition of the catalyst as an example, in order to maintain the properties of the catalyst itself and to have a high catalytic efficiency after the catalyst is put into the reaction, the surface of the catalyst is generally set to a rough and uneven shape, and liquid white oil is set on the catalyst surface to isolate and seal it from the air. The surface of the catalyst placed in the storage room 13 retains liquid white oil, and this part of the liquid white oil will gradually accumulate to the bottom of the feeding box 1 after dripping from the catalyst surface. By setting the drain port 17 at the bottom of the feeding box 1, it is more convenient to collect the dripping liquid, and it is also more convenient to clean the inside of the collection box.

[0089] In some embodiments, the feeding box 1 is further provided with an observation window, which is located at the discharge port 11, so as to observe whether there is a blockage or other problems at the discharge port 11.

[0090] refer to Figure 2 and Figure 4A retaining edge 18 is provided at the bottom of the feeding box 1, and the retaining edge 18 is located on the side of the discharge port 11 facing the liquid discharge port 17, and the lower end of the bottom surface of the feeding channel 12 is located in the direction of the retaining edge 18 toward the liquid discharge port 17, that is, when the liquid drips along the bottom surface of the feeding channel 12 to the bottom of the feeding box 1, the dripping position is located on the side of the retaining edge 18 facing the liquid discharge port 17, thereby preventing the dripping liquid from being discharged from the discharge port 11.

[0091] refer to Figure 2 and Figure 3 A plurality of baffles 4 are fixedly connected inside the feeding box 1, and the storage room 13 is a space area separated by the cooperation of the baffles 4, the side wall of the feeding box 1 and the closure 3. In addition, a feed plate 5 is fixed, and the feeding channel 12 is the channel area between the feed plate 5 and the storage room 13.

[0092] The closure 3 includes a plurality of gates 31, and the plurality of gates 31 correspond to the plurality of communication ports one by one. The gates 31 rotate relative to the baffle 4 to open and close the communication ports. The gates 31 are hinged to the side walls of the storage room 13. In actual settings, the gates 31 can be directly hinged to the baffle 4, or a bracket can be installed in the feeding box 1 and the gates 31 can be hinged to the bracket. The embodiment of the present application is described by taking the bracket installed in the feeding box 1 and the gates 31 hinged to the bracket as an example.

[0093] The closure member 3 also includes a driving member 32, which is fixedly connected to the feeding box 1, and the output end of the driving member 32 is connected to the gate 31 to drive the gate 31 to rotate relative to the baffle 4 to control the opening and closing of the connecting port. Exemplarily, the driving member 32 is a rotary cylinder, and the output end of the rotary cylinder is connected to the gate 31, driving the gate 31 to swing between the closed and open states, which can more conveniently achieve the adjustment of the gate 31. In addition, the driving member 32 and the power member 22 both adopt a pneumatic structure, which greatly reduces the risk of danger compared to the use of electrical equipment, especially when feeding flammable and explosive materials.

[0094] refer to Figure 5 The feeding system is also provided with a control system 6 to more accurately and conveniently adjust the specific actions of each component; the control system 6 is provided with an input module 61, and the staff inputs corresponding parameters through the input module 61, such as the number of materials in each storage room 13, the time speed of feeding materials, the total amount of feeding materials, etc. Exemplarily, the input module 61 is a touch-sensitive display screen, or a display screen equipped with input buttons.

[0095] The control system 6 is connected with the power member 22 and the driving member 32 by signals to smoothly realize the material feeding action; specifically, in the initial state, the groove 211 on the feeding roller 21 is opposite to the feeding port 14. After the feeding process starts, the control system 6 controls the driving member 32 to operate, opens one of the gates 31, and the material in the corresponding storage room 13 rolls into the feeding channel 12, and falls into the groove 211 through the feeding port 14 in turn. Then, the control system 6 controls the power member 22 to drive the feeding roller 21 to rotate, transfers the material in the groove 211 to the discharge port 11 and drops it, and then rotates to the corresponding position of the groove 211 and the feeding port 14 to complete a material feeding action.

[0096] After the materials in one material storage room 13 are put into place, the control system 6 controls the driving member 32 to open another gate 31, and the materials in the corresponding material storage room 13 roll into the feeding channel 12, and the material putting process continues.

[0097] Exemplarily, multiple gates 31 are opened in sequence from a direction away from the feeding port 14 to a direction close to the feeding port 14. On the one hand, it is convenient to determine the amount of material in each storage room 13 according to the data in the input value control system 6, so as to judge the time to open the next gate 31; on the other hand, each gate 31 is opened in sequence subsequently, and there is no need to close the previously opened gate 31, and the feeding channel 12 will not be blocked, which improves the convenience of using the feeding system.

[0098] refer to Figure 4 and Figure 5 The feeding system is also provided with a counter 7 connected to the control system 6 signal. The counter 7 is fixed on the inner wall of the feeding box 1 and is located at the discharge port 11. It is used to detect the amount of material fed, that is, the amount of material passing through the discharge port 11.

[0099] By setting the counter 7, in the specific material delivery process, the amount of delivered materials is detected in real time, and the detection result is fed back to the control system 6, and compared with the relevant data pre-input in the control system 6, the time point when the control system 6 controls the power member 22 and the driving member 32 to act can be more accurately determined. It is also possible to determine whether the actual amount of delivered materials is the same as the pre-set requirements by detecting the actual amount of delivered materials, so as to facilitate timely discovery and adjustment in the event of deviations.

[0100] In some embodiments, the feeding system also includes a posture sensor 8 connected to the control system 6 signal. The posture sensor 8 is fixed in the feeding box 1 and is located at a position corresponding to the feeding roller 21. It is used to detect the state of the feeding roller 21; illustratively, the position of the groove 211 on the feeding roller 21 is detected.

[0101] In the initial stage of feeding materials, it is necessary to ensure that the groove 211 is in the state of the feeding port 14 to ensure that the materials discharged from the feeding port 14 can be smoothly received; the posture sensor 8 detects the state of the feeding roller 21. If it is in the correct initial state, the control system 6 controls the subsequent feeding process; if it is detected that it is not in the correct initial state, the control system 6 controls the power part 22 to adjust the feeding roller 21 to the correct initial state. The staff does not need to observe or adjust during the process, which greatly improves the convenience of use.

[0102] Among them, the counter 7 and the posture sensor 8 can be set as infrared sensors, photoelectric sensors, etc. commonly used in the relevant fields. When detecting the state of the feeding roller 21, the position of the groove 211 can be detected, and the cross section of the feeding roller 21 can be set to be irregular (irregular means non-circular), so that the posture sensor 8 is triggered only when the feeding roller 21 is in the initial state, or the posture sensor 8 is not triggered only when the feeding roller 21 is in the initial state. In actual use, different types can be set according to actual needs, and it is only necessary to be able to determine the position of the groove 211 on the feeding roller 21.

[0103] In some embodiments, the control system 6 is also connected to the gas supply device signal to control the timing and amount of gas introduced into the feeding box 1; or a solenoid valve is set at the air inlet 15, and the solenoid valve is connected to the control system 6 signal, which can also realize the regulation of the ventilation process.

[0104] In addition, a pressure sensor connected to the inside of the feeding box 1 is provided, and the air pressure inside the feeding box 1 is detected by the pressure sensor. When the pressure is too high, an alarm signal is triggered, and the staff makes timely adjustments to avoid danger. In actual use, the control system 6 can add or delete corresponding functions according to actual needs, and the corresponding workflow and control standards are set according to needs, and this part will not be repeated in the embodiment of the present application.

[0105] refer to Figure 2 The bottom surface of the feeding channel 12, that is, the surface on which the material is carried on the material discharge plate 5, has an angle α with the horizontal plane, and α satisfies: 30°≤α≤70°. The bottom surface of the storage room 13, that is, the surface on which the material is carried on the baffle plate 4, has an angle β with the horizontal plane, and β satisfies: 30°≤β≤70°, and the inclination direction of the baffle plate 4 is opposite to the inclination direction of the material discharge plate 5, so that Figure 2 Taking the state shown as an example, the opposite tilting direction referred to here specifically means that the upper ends of the blanking plate 5 and the baffle plate 4 tilt to the left and right sides respectively.

[0106] By setting the inclination angles of the unloading plate 5 and the baffle plate 4 within the corresponding range, the smooth movement of materials in the feeding channel 12 and the storage room 13 is ensured; especially for materials whose cross-sectional shapes are greatly different from the circular shape, for example, the cross-sectional shape of the rod-shaped material is elliptical, etc., the problem of the unloading plate 5 and the baffle plate 4 not being able to roll down smoothly due to the inclination angle being too small can be avoided.

[0107] In addition, if the inclination angle is too large, there will be a more violent collision when the material falls, and the material may be damaged due to bumps and debris may fall, resulting in material waste and difficulty in ensuring the quantitative delivery of the material; moreover, in the case where the material is an active catalyst, the collision of the material may cause the catalyst to catch fire or explode. Limiting the inclination angle of the discharge plate 5 and the baffle 4 can avoid obvious and violent collisions and improve safety.

[0108] In actual design, the inclination angles of the unloading plate 5 and the baffle 4 can be adjusted according to actual conditions, as long as they can ensure smooth transfer of materials and avoid violent collisions of materials.

[0109] In addition, for the gate 31, its rotation angle should ensure that when the corresponding connecting port is closed, it does not hinder the passage of materials in the feeding channel 12, and when it is open, it does not hinder the passage of materials in the storage room 13 through the connecting port, and avoids interference between the gate 31 and the unloading plate 5.
