Description

Technical Field

[0001] This utility model relates to the field of cocoa bean conveying and weighing technology, and in particular to a vacuum feeding flow scale for cocoa bean conveying. Background Technology

[0002] In the cocoa bean processing process, cocoa beans need to be transported from storage silos to processing equipment, and the flow rate needs to be precisely controlled. The conveyor system typically uses separate conveying and weighing equipment, which presents the following problems: Traditional cocoa bean conveyors usually consist of multiple independent devices, such as vacuum feeders, static weighing scales, and conveyors. These devices are scattered and occupy a lot of space. During the transport process, the open conveyor system may allow cocoa beans to be contaminated by external factors (such as dust, foreign objects, etc.), affecting product quality. Summary of the Invention

[0003] To address the problems of existing equipment being scattered, complex, space-consuming, and easily contaminated during transport, this invention provides a vacuum feeding flow scale for cocoa bean transport. By fixing a weighing device, a storage silo, and a vacuum feeder on a support frame, and connecting a continuous discharge device to the lower part of the storage silo, feeding, weighing, and transport are integrated into one device, reducing the equipment's footprint, simplifying installation and maintenance processes, and preventing cocoa beans from being contaminated during transport.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vacuum feeding flow meter for conveying cocoa beans includes a support frame, a vacuum feeder, and a storage hopper. A weighing device is fixed on the support frame, and the storage hopper is fixed on the weighing device. The feeding port of the storage hopper is connected to the vacuum feeder for feeding; the discharging port of the storage hopper is connected to a continuous discharging device. This device integrates the feeding, weighing, and conveying processes into a single unit, reducing the equipment footprint and simplifying installation and maintenance. Furthermore, the integrated enclosed design of the vacuum feeder, storage hopper, and continuous discharging device prevents contamination of the cocoa beans during transport.

[0005] Furthermore, the weighing device includes multiple pressure sensors, which are circumferentially spaced and fixed to the upper part of the support. The storage hopper is equipped with supports corresponding to the pressure sensors, and these supports are fixedly connected to the pressure sensors. The pressure sensors monitor changes in cocoa bean flow rate in real time, controlling the flow rate to meet the needs of refined production.

[0006] Furthermore, the continuous discharge device includes a temporary storage bin, a conveying device, and a monitoring device. The temporary storage bin is connected to the storage bin, and a monitoring device is fixed on the temporary storage bin to monitor changes in the height of the cocoa beans inside. The discharge port of the temporary storage bin is connected to the conveying device. Through the setup of the temporary storage bin, conveying device, and monitoring device, the cocoa beans stored in the temporary storage bin can maintain a continuous supply from the auger conveyor, ensuring production stability.

[0007] Furthermore, the monitoring device is a level gauge. By monitoring the level of cocoa beans in the temporary storage bin in real time, the storage bin can be replenished promptly, achieving continuous feeding and improving production efficiency.

[0008] Furthermore, the conveying device is an auger conveyor; the auger conveyor includes a drive unit, a conveying pipe and a transmission shaft, one end of the transmission shaft is connected to the drive unit and the other end passes through the conveying pipe and is disposed inside the conveying pipe, the transmission shaft is rotatably connected to the conveying pipe, a spiral blade is fixed on the transmission shaft, and the conveying pipe has an inlet and an outlet; the inlet is connected to a temporary storage bin; multiple filter devices for filtering residues are also connected to the conveying pipe.

[0009] Furthermore, the filtration device includes a top cover, a filter screen, and a residue storage bin. The top cover and the filter screen are detachably connected, and both the top cover and the filter screen are connected to a conveying pipeline. The residue storage bin is detachably connected to the outside of the top cover and the filter screen.

[0010] Furthermore, both the top cover and the filter screen are arc-shaped structures, arranged vertically, and together they form a cylindrical structure. The top cover and the filter screen are rotatably connected by pins, and flanges are fixed at both ends of the top cover and the filter screen. The conveying pipe is connected to the top cover and the filter screen through the flanges.

[0011] Furthermore, the slag storage bin is a horizontally arranged cylindrical shell with an axially penetrating hollow cavity inside. The top of the slag storage bin has an axial opening to facilitate fitting the slag storage bin onto the cylindrical structure formed by the top cover and the filter screen. The two ends of the opening of the slag storage bin have flanges extending outward, and the two flanges are connected by bolts.

[0012] Furthermore, a butterfly valve connects the storage silo and the temporary storage silo. This allows for rapid response and timely replenishment of cocoa beans, enabling continuous production while preventing the impact of large amounts of falling cocoa beans on the temporary storage silo and conveying equipment.

[0013] The beneficial effects of this utility model through the above technical solution are: This invention integrates feeding, weighing, and conveying into one device by setting a weighing device, a storage bin, and a vacuum feeder on the upper part of the support frame, and connecting a continuous discharge device at the lower part of the storage bin. This reduces the equipment footprint, simplifies the installation and maintenance process, and prevents cocoa beans from being contaminated during the conveying process.

[0014] This invention, by installing a butterfly valve and a continuous discharge device at the bottom of the storage silo, can quickly respond and replenish cocoa beans in a timely manner, achieving continuous material supply and improving production efficiency.

[0015] This invention uses a weighing device and a level gauge to monitor the changes in cocoa bean flow rate in the storage silo and temporary storage silo in real time, and adjusts the cocoa bean flow rate and conveying speed of the conveying equipment in a timely manner to ensure continuous feeding, improve the stability of equipment operation, and prevent large flow fluctuations that could cause cocoa beans to accumulate in the storage silo and affect the normal operation of the equipment.

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-7 As shown, a vacuum feeding flow meter for cocoa bean conveying includes a support 1, a vacuum feeder 2, and a storage bin 3. A weighing device is fixed on the support 1, and the storage bin 3 is fixed on the weighing device. Specifically, the weighing device includes multiple pressure sensors 4, which are circumferentially spaced and fixed on the upper part of the support 1. In this embodiment, there are four pressure sensors 4. A support 5 corresponding to the pressure sensors 4 is fixed to the outer wall of the storage bin 3, and the support 5 is fixedly connected to the pressure sensors 4. The vacuum feeder 2 is fixed on the upper part of the storage bin 3, and the discharge port of the vacuum feeder 2 is connected to the feeding port of the storage bin 3. A continuous discharge device is connected to the lower part of the storage bin 3, concentrating the feeding, weighing, and conveying processes into one device, reducing the equipment footprint, simplifying the installation process, and preventing cocoa bean contamination caused by exposed transportation. By setting up the pressure sensors 4, the cocoa bean flow rate changes are monitored in real time, and the feeding flow rate is controlled to meet the needs of refined production.

[0025] The discharge port of storage silo 3 is connected to a continuous discharge device, which includes a temporary storage silo 6, a conveying device, and a monitoring device. A butterfly valve 8, which is a pneumatic butterfly valve, is connected to the discharge port of storage silo 3. The temporary storage silo 6 is connected to the butterfly valve 8. The temporary storage silo 6 mitigates fluctuations in material replenishment to storage silo 3 and material transport by the downstream conveying device, ensuring the continuity of cocoa bean transport. A monitoring device, a level gauge 9, is connected inside the temporary storage silo 6 to monitor changes in the height of the cocoa beans. In this embodiment, a rotary paddle level switch is used. A conveying device, namely an auger conveyor 7, is connected to the discharge point of the temporary storage bin 6. The auger conveyor 7 includes a drive unit 12, a conveying pipe 16, and a transmission shaft 13. One end of the transmission shaft 13 is connected to the drive unit 12, and the other end passes through the conveying pipe 16 and is disposed inside the conveying pipe 16. The transmission shaft 13 is rotatably connected to the conveying pipe 16. A spiral blade 14 is fixed on the transmission shaft 13. The conveying pipe 16 has an inlet 11 and an outlet 15. The inlet 11 is connected to the temporary storage bin 6 to ensure the airtightness of the cocoa beans during transport and prevent contamination. The flow rate of cocoa beans is controlled by a butterfly valve 8 and a continuous discharge device to replenish cocoa beans in a timely manner and achieve continuous production.

[0026] In this embodiment, the vacuum feeder 2, pressure sensor 4, level gauge 9, butterfly valve 8, and screw conveyor 7 are all controlled by PLC.

[0027] During operation of the auger conveyor, cocoa beans may be damaged due to compression. To promptly discharge the damaged cocoa beans and prevent them from flowing into the next process and affecting product quality, multiple filter devices 10 are installed on the conveying pipe 16. In this embodiment, there are two filter devices. Figures 4-6 As shown, the filtration device 10 includes an upper cover 104, a filter screen 105, and a residue storage bin 101. Both the upper cover 104 and the filter screen 105 are arc-shaped structures, arranged vertically. When connected and combined, the upper cover 104 and the filter screen 105 form a cylindrical structure. The upper cover 104 and the filter screen 105 are detachably connected. In this embodiment, the upper cover 104 and the filter screen 105 are connected by pins. Rings 102 are installed on both sides of the upper cover 104 and both sides of the filter screen 105. Pins are inserted between corresponding rings 102 on the same side of the upper cover 104 and the filter screen 105. Both the upper cover 104 and the filter screen 105 are connected to a conveying pipe 16. Specifically, flanges are fixed at both ends of the upper cover 104 and the filter screen 105, and the conveying pipe 16 is connected to the upper cover 104 and the filter screen 105 through the flanges.

[0028] The slag storage bin 101 is detachably connected to the outside of the upper cover 104 and the filter screen 105. The slag storage bin 101 is a horizontally arranged cylindrical shell with an axially penetrating hollow cavity inside. The top of the slag storage bin 101 has an axial opening to facilitate fitting the slag storage bin 101 onto the cylindrical structure formed by the upper cover 104 and the filter screen 105. The two ends of the opening of the slag storage bin 101 have flanges 103 extending outward, and the two flanges 103 are connected by bolts.

[0029] When cocoa bean residue passes through filter screen 105, it flows into the residue storage bin 101, preventing excessive residue accumulation from clogging the conveyor housing and affecting conveying efficiency. The top cover 104 and filter screen 105 are connected by a pin. When cleaning the inside of the conveyor is required, the residue storage bin 101 can be disassembled, and the pin connecting the top cover 104 and filter screen 105 can be removed to clean the inside of the auger conveyor 7 and prevent further clogging. During operation, pressure sensor 4 continuously monitors whether the weight of the storage bin 3 is lower than a preset value. When it is lower than the preset value, feedback is sent to the PLC, which sends a start signal to the vacuum tube feeder 2. The vacuum feeder 2 is connected to an external suction pipe to the material location, and the vacuum feeder 2 sucks cocoa beans into the storage bin 3 through the suction pipe. When the preset value is reached, pressure sensor 4 sends a signal to the PLC, which controls the vacuum feeder 2 to shut down and stop feeding.

[0030] The level gauge 9 in the temporary storage bin 6 monitors the changes in the stacking height of cocoa beans. When the stacking height of cocoa beans is lower than the preset value, a feedback signal is sent to the PLC. The PLC controls the butterfly valve 8 to open, allowing cocoa beans in the storage bin 3 to enter the temporary storage bin 6. After the preset value is reached, the level gauge 9 sends a feedback signal, and the PLC controls the butterfly valve 8 to close, thus replenishing the cocoa beans in the temporary storage bin 6. As a result, the temporary storage bin 6 can continuously supply material to the auger conveyor 7, enabling continuous transport of cocoa beans to the processing equipment, ensuring production continuity and improving work efficiency.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
