Embodiment 1

[0035] As Figures 1 - 3 shown, this embodiment provides a granulating device 100 for manufacturing granular materials. The granulating device 100 includes a controller, a feed hopper 11, and a granulator 12 connected to the outlet of the feed hopper 11. A blanking valve 13 is provided at the connection between the feed hopper 11 and the granulator 12 to adjust the opening degree of the material entering the inlet of the granulator 12. And a flow detector 14 is provided on the granulator 12 to detect the material flow rate in the chamber of the granulator 12. Among them, the blanking valve 13 and the flow detector 14 are respectively electrically connected to the controller, so that the controller can make a judgment according to the material flow rate signal detected by the flow detector 14 in the granulator 12, and then send an instruction to the blanking valve 13 to adjust the opening degree of the inlet of the granulator 12.

[0036] Through the integration of the controller, the flow detector 14, and the blanking valve 13, the real-time monitoring and automatic adjustment of the material flow in the granulator 12 are realized, ensuring the stable working state of the granulator 12, avoiding problems such as material pouring, and also reducing the need for manual intervention. Moreover, the automated operation process can not only reduce the downtime caused by manual operation and improve production efficiency, but also reduce the possibility of human error operation through the precise control of the flow detector 14 and the controller, improving the reliability of the granulation device 100. In addition, since the operator does not need to frequently climb to operate the manual valve, the risk of falling and tripping is reduced, improving the operation safety.

[0037] In this embodiment, the outlet end of the feed hopper 11 is embedded in the inlet end of the granulator 12, and the blanking valve 13 is arranged at the inlet of the granulator 12 to adjust the inlet opening for the material to flow through at the inlet of the granulator 12. In other embodiments, the blanking valve 13 can also be arranged at the outlet of the feed hopper 11. The specific connection method between the feed hopper 11 and the granulator 12 and the specific setting position of the blanking valve 13 are not limited, as long as it can adjust the opening of the through-hole for the material to flow into the granulator 12.

[0038] As Figure 2 shown, an opening and closing detection member 15 is further provided on the blanking valve 13 to detect the situation of the blanking valve 13 adjusting the inlet of the granulator 12. Among them, the opening and closing detection member 15 is electrically connected to the controller, so that the opening and closing detection member 15 can send the situation signal of the inlet of the granulator 12 to the controller, and the controller can send an instruction to the blanking valve 13 to adjust the opening of the inlet of the granulator 12 after receiving it. Among them, the opening and closing detection member 15 can monitor the opening and closing state of the blanking valve 13 relative to the inlet of the granulator 12 in real time, ensuring that the controller can obtain accurate position information of the blanking valve 13 to achieve more precise material flow control; and it can also timely detect possible failures or abnormalities of the blanking valve 13, such as jamming, incomplete opening or closing, etc., and can timely send the state information of the blanking valve 13 to the controller, so as to take measures to avoid the failure of the granulation device 100.

[0039] Preferably, the granulation device 100 further includes a display screen (not shown in the figure) electrically connected to the controller for displaying the instruction information received from the controller.

[0040] Therefore, before the granulator 12 runs, when the opening and closing detector 15 detects that the feeding valve 13 does not close the inlet of the granulator 12, it can send a fault signal to the controller, and the granulator 12 will not start running and will emit an audible and visual alarm. After receiving the signal, the controller can send an instruction to the display screen to display the fault information. Only after the fault is processed and reset can the next step be executed. In this way, the operator can intuitively understand the current situation of the feeding valve 13 relative to the inlet of the granulator 12 through the display screen and adjust the feeding valve 13 in time, effectively avoiding the problem of material pouring caused by the feeding valve 13 not being tightly closed and ensuring the normal processing process of subsequent materials.

[0041] Furthermore, the opening and closing detector 15 specifically includes a detection end 151 and a mobile end 152 that are electrically connected to each other. The feeding valve 13 can adjust the opening degree of the inlet of the granulator 12 by moving relative to the granulator 12. Therefore, the detection end 151 is arranged at the connection between the feed hopper 11 and the granulator 12, preferably on the granulator 12, and the mobile end 152 is arranged at a position where the feeding valve 13 can move relative to the granulator 12. Preferably, the mobile end 152 is arranged on the surface of the feeding valve 13 facing the detection end 151, so that the distance between the two is the shortest, improving the signal transmission speed and accelerating the response rate of the detection end 151.

[0042] Among them, the detection end 151 can detect the opening degree of the inlet of the granulator 12 adjusted by the feeding valve 13 according to the distance of the mobile end 152 relative to it, and send the signal of the inlet opening degree to the controller. After receiving the signal, the controller makes a judgment and then sends an instruction to the feeding valve 13 to adjust the opening degree of the inlet of the granulator 12.

[0043] By using the distance method to judge the position of the feeding valve 13 relative to the inlet of the granulator 12, that is, to detect the opening degree of the feeding valve 13, the material flow rate at the inlet of the granulator 12 can be accurately controlled. In this way, the principle is simple and effective, and it can accelerate the response rate of the opening and closing detector 15 and improve its detection efficiency.

[0044] Specifically, in this embodiment, the feeding valve 13 is a driving motor or a driving cylinder, which can provide accurate power output, make the opening degree control of the feeding valve 13 more accurate, and thus accurately control the material flow rate. Moreover, the driving motor or the driving cylinder has a fast response speed and can quickly adjust the opening degree of the feeding valve 13 to respond to the signal change of the flow detector 14 in time.

[0045] As a preferred embodiment, the granulator 12 is electrically connected to the controller, so that after the granulator 12 operates, it can send a signal of its operation to the controller, and after receiving the signal, the controller can send an instruction to the feeding valve 13 to open the inlet of the granulator 12. This automated startup process reduces manual intervention and also enables the opening of the feeding valve 13 to be precisely controlled by the controller each time it starts, ensuring the consistency and repeatability of the operation.

[0046] As a preferred embodiment, the granulator 12 is electrically connected to the controller, so that after the flow detector 14 detects that no material enters the granulator 12, it can send a signal to the controller. After receiving the signal, the controller can send an instruction to the feeding valve 13 to close the inlet of the granulator 12 and send an instruction to the granulator 12 to stop operating. In this way, when the flow detector 14 detects that the material flow stops, it will automatically trigger the shutdown procedure of the granulator 12 through the controller, preventing the granulator 12 from idling, reducing energy waste and equipment wear.

[0047] As Figure 3 shown, the flow detector 14 is arranged on the outer side surface of the granulator 12 and is located at the outlet end of the granulator 12. The detection end 151 of the flow detector 14 can extend into the chamber of the granulator 12 to detect the material flow in the chamber, improving the accuracy and reliability of the detection. Moreover, the flow detector 14 located at the outlet end can monitor the material flow situation in real time and respond to the flow change in a timely manner to ensure the stable flow of the material flow in the granulator 12. In addition, the external flow detector 14 reduces the possible interference in the chamber of the granulator 12 on the detection, such as material impact, etc., ensuring the accuracy and integrity of the detection, and the flow detector 14 arranged on the outer side of the granulator 12 is convenient for maintenance and replacement without disassembling the granulator 12.

[0048] Preferably, the number of the flow detectors 14 is multiple, and the multiple flow detectors 14 are evenly distributed on the outer wall surface of the granulator 12. The multiple flow detectors 14 can monitor the material flow inside the granulator 12 from different positions, ensuring the comprehensiveness and accuracy of the monitoring data, and can more accurately judge the actual situation of the material flow, reducing the error that may occur in single-point detection.

[0049] In other embodiments, the flow detector 14 can be annularly wound around the outer wall surface of the granulator 12 or symmetrically arranged on the outer wall surface of the granulator 12. The specific setting method of the flow detector 14 is not specifically limited, as long as it meets the requirement for detecting the material flow in the chamber of the granulator 12.

[0050] Meanwhile, in this embodiment, both the flow detector 14 and the opening / closing detector 15 are sensors, which utilize infrared ray technology or ultrasonic technology to perform high-precision detection on the required components. Moreover, the controller can be a programmable logic controller (PLC), which can be set as needed in other embodiments.

[0051]

Embodiment 2

[0052] As Figures 4 - 6 shown, this embodiment provides a particle sizing and screening device 200, which includes a screening device 300 and the sizing device 100 described in Embodiment 1 above. The inlet end of the screening device 300 is connected to the outlet end of the sizing device 100 for screening particulate materials.

[0053] Among them, the screening device 300 includes a vibratory screen 31, a receiving buffer bin 32, a turnover barrel 33, and a vacuum feeder 34 that are connected in sequence from start to end. The inlet end of the vibratory screen 31 is in communication with the outlet end of the granulator 12, enabling particulate materials to enter the vibratory screen 31 for the next process. The particle sizing and screening device 200 further includes a control box 21, a lifting column 22, a tipping head 23, a rotating shaft 24, and a granulator bin 25.

[0054] As Figure 4 shown, the controller is arranged in the control box 21, and the control box 21 is arranged on the lifting column 22. There is a track on the lifting column 22 for the tipping head 23 to move up and down. The granulator bin 25 is connected to the tipping head 23 through the rotating shaft 24, and the granulator bin 25 is fixedly connected to the feed hopper 11 through a buckle. In this way, the tipping head 23 can drive the granulator bin 25 and the feed hopper 11 to flip through the rotating shaft 24 to achieve the up and down position exchange of the feed hopper 11 and the granulator bin 25, and can also drive the feed hopper 11, the granulator bin 25, and the granulator 12 to move up and down along the extension direction of the column. Among them, the feed hopper 11 is used to connect to the granulator bin 25, so that the particulate materials in the granulator bin 25 are transferred into the feed hopper 11 and smoothly flow into the granulator 12 for sizing. And the opening degree of the feed valve 13 at the connection between the feed hopper 11 and the granulator 12 can be freely set to control the materials in the feed hopper 11 to flow into the granulator 12 at a certain flow rate, so that all the flowing materials can be processed into particles within the qualified particle size range, and the granulator 12 can be prevented from being stuck due to being filled with materials.

[0055] Secondly, the outlet end of the vibratory screen 31 is connected to the outlet end of the granulator 12 for screening the material. The outlet end of the vibratory screen 31 is connected to the inlet end of the receiving buffer bin 32. The receiving buffer bin 32 is further connected to the turnover barrel 33 through a pipeline. The turnover barrel 33 is then connected to the vacuum feeder 34 through a ventilation pipe. Except for the granulating device 100, the above are all prior arts, and the specific connection method and working principle will not be elaborated.

[0056] Therefore, as Figures 4 - 6 , the following introduces the working process of the particle granulating and screening equipment 200 in Embodiment 2 of the present application in combination with specific application scenarios, as follows:

[0057] (1) Material receiving: The granulator bin 25 is placed on the cart 400. When the granulator discharges materials, the operator takes the materials into the granulator bin 25. When reaching the appropriate position, stop receiving materials, and then transfer the materials to the particle granulating and screening equipment 200 through the cart 400.

[0058] (2) Material transfer: The operator transfers the granulator bin 25 to directly below the feed hopper 11 through the cart 400.

[0059] (3) Feeding: The operator operates the control box 21 to lower the tipping head 23, the feed hopper 11, and the granulator 12 as a whole above the granulator bin 25 on the cart 400. The feed inlet of the feed hopper 11 is attached to the granulator bin 25, and the locking buckle on the feed hopper 11 is tightened. The granulator bin 25 is fixed on the feed hopper 11, and the feed hopper 11 cooperates with the granulator bin 25. Operate the control box 21, and the rotary shaft 24 rotates 180°. When the feed hopper 11 and the granulator bin 25 are buckled and the feed valve 13 between the discharge outlet of the feed hopper 11 and the feed inlet of the granulator 12 is opened, the material enters the feed inlet of the granulator 12 through the discharge outlet of the feed hopper 11.

[0060] (4) Granulating: The discharge outlet of the feed hopper 11 is connected to the feed inlet of the granulator 12. The material enters the granulator 12 under the action of gravity. When the granulator 12 is started, after the material enters the granulator 12, it is pre-pressed by the scraper pre-pressing device. The scraper pre-pressing device consists of a set of scrapers and rollers. The scraper squeezes and shears the material by being fixed on the roller, thereby forming a uniform and dense material. After granulating treatment, the material is discharged from the discharge outlet of the granulator 12 and enters the vibratory screen 31.

[0061] (5) Screening: The material enters the vibratory screen 31 for screening, and after screening, it enters the receiving buffer bin 32.

[0062] (6) Stockpiling: When particles with a particle size of 30 - 60 mesh flow into the receiving buffer bin 32, turn on the vacuum feeder 34. A negative pressure is formed from the receiving buffer bin 32 to the front end of the vacuum feeder 34. The particles in the receiving buffer bin 32 flow through the pipeline into the turnover bucket, and the material falls into the turnover bucket without flowing backward into the vacuum feeder 34.

[0063] The above description has fully disclosed the specific implementation manners of the present application. It should be noted that any modifications made by those skilled in the art to the specific implementation manners of the present application do not depart from the scope of the claims of the present application.
