[0036] In order to make the technical problems, technical schemes and advantages to be solved by the utility model more clear, the following will be described in detail in combination with the drawings and specific embodiments.

[0037] As Figs. 1-3 shown, the embodiment of the utility model provides an automatic pot filling device, including container 10, transport structure 20, fan structure 30 detection structure 40 and central control module 50. The container 10 top end is provided with a feeding port, and the container 10 is used to contain the material to be cooked, and in the pulp mill, the material is usually wood chip, and based on the volume of the container 10, the maximum loading line 11 and the minimum loading line 12 are arranged on the inner wall of the container 10, and it can be understood that the maximum loading line 11 is located above the minimum loading line 12. The transport structure 20 is further provided above the container 10, and the transport structure 20 has a beginning end and an end, and the end of the transport structure 20 is arranged above the feeding port, and the beginning end is located at the raw material, and under the transport of the transport structure 20, the material is transported from the raw material to the above of the feeding port and falls in the container 10 to complete filling. The fan structure 30 is communicated with the container 10 for extracting the gas in the container 10, so that the gas pressure environment in the container 10 is lower than the atmospheric pressure, and the material collapses under the action of the atmospheric pressure, avoiding that the material does not reach the preset weight in the process of filling. The foregoing detection structure 40 is arranged in the container 10, and the detection structure 40 judges the current loading capacity of the container 10 through the vibration signal of itself. The central control module 50 is signal connected with the transport structure 20, the fan structure 30 and the detection structure 40 respectively, and is used to control the working state of each component.

[0038] Specifically, in the present application, the transport structure 20 sends a weight signal to the central control module 50, the weight signal is the signal of the cumulative weight of the material weighed in the transport process of the transport structure 20, and by obtaining the weight signal of the cumulative weighed material, the total weight of the material put into the container 10 in the working process of the transport structure 20 can be judged. Based on the preset total weight, the central control module 50 can also send a first start-stop signal to the transport structure 20, and the first start-stop signal controls the working state of the transport structure 20. Specifically, when the total weight of the weighed material is less than the preset total weight, the transport structure 20 maintains the moving state and continuously feeds the material into the container 10. When the total weight of the weighed material reaches the preset total weight, the central control module 50 sends a first start-stop signal to the transport structure 20 to stop the feeding of the transport structure 20.

[0039] The aforementioned fan structure 30 receives a second start-stop signal sent by the central control module 50, and the second start-stop signal controls the working state of the fan structure 30. Specifically, when the central control module 50 sends a first start-stop signal to the transport structure 20 to drive the transport structure 20 to work, the central control module 50 synchronously sends a second start-stop signal to the fan structure 30, and the fan structure 30 starts to work based on the second start-stop signal to exhaust the gas in the container 10, so that the gas pressure in the container 10 is the first atmospheric pressure.

[0040] The aforementioned detection structure 40 sends a detection signal to the central control module 50, and the central control module 50 judges the current filling amount of the container 10 based on the detection signal. In the present application, the detection structure 40 is a vibration rod sensor (also known as a vibration rod material level switch), and the vibration rod sensor selects a normally open vibration rod sensor which can continuously generate an electric signal. When the material surrounds the vibration rod sensor, the vibration rod sensor stops vibrating and no longer generates an electric signal, and the central control module 50 judges the current loading amount by judging whether the vibration rod sensor generates an electric signal.

[0041] Further, the automatic pot filling device further comprises a warning structure 60, the warning structure 60 receives a first warning signal or a second warning signal sent by the central control module 50, and the warning structure 60 makes different warning signals according to the first warning signal or the second warning signal.

[0042] In the present embodiment, the warning structure 60 is a warning bell, and after receiving the first warning signal, the warning bell sends a warning bell sound lasting for 30 seconds. After receiving the second warning signal, the warning light sends a short warning bell sound.

[0043] The aforementioned detection structure 40 is arranged at the maximum loading line 11 of the container 10, at the minimum loading line 12, or at a position between the maximum loading line 11 and the minimum loading line 12.

[0044] Specifically, the vibrating rod sensor comprises a detection end and a non-detection end. When the vibrating rod sensor is arranged at the maximum loading line 11 of the container 10, the non-detection end of the vibrating rod sensor is fixed on the side wall of the container 10, and the detection end is arranged in an inclined manner downward below the maximum loading line 11 of the container 10.

[0045] When the vibrating rod sensor is arranged at the minimum loading line 12 of the container 10, the non-detection end of the vibrating rod sensor is fixed on the bottom wall of the container 10, and the detection end is arranged in an inclined manner upward above the minimum loading line 12.

[0046] When the vibrating rod sensor is arranged between the maximum loading line 11 and the minimum loading line 12 of the container 10, the non-detection end of the vibrating rod sensor is fixed on the bottom wall of the container 10, and the detection end is arranged in an inclined manner downward above the vibrating rod sensor. In addition, a protective cover 41 is arranged above the vibrating rod sensor, which shields the detection structure 40 from above the vibrating rod sensor to avoid the vibrating rod sensor from being damaged by the falling materials.

[0047] It should be noted that the vibrating rod sensor is installed at one of the above three positions, and the vibrating rod sensor judges whether the materials are accumulated to the installation position of the vibrating rod sensor.

[0048] In the embodiment, in order to realize the functions of transportation and weighing, the transportation structure 20 is a transportation belt with a weighing function.

[0049] In the embodiment, the fan structure 30 is a negative pressure fan, which is connected to the middle and lower part of the container 10.

[0050] Preferably, the central control module 50 is further signal-connected with a display screen, which is used to display the working states of various components and interactive buttons for controlling the central control module 50 to perform different program operations.

[0051] The control logic of the central control module 50 is a prior art, and thus will not be described in detail.

[0052] In the working process of the application, the operator sends a command of preparing to load a pot to the central control module 50. After receiving the command of preparing to load a pot, the central control module 50 sends a second start-stop signal to the fan structure 30, and the fan structure 30 starts to work to form a low-pressure environment in the container 10. At the same time, the central control module 50 also sends a first warning signal to the warning structure 60, and the warning structure 60 rings for 30 seconds to remind the on-site personnel to keep away.

[0053] Subsequently, the operator issues a command of potting to the central control module 50, and the central control module 50 receives the command of potting and sends a first start-stop signal to the transport structure 20, and the transport structure 20 starts to work and pours the material into the container 10. During the pouring process, the transport structure 20 transmits the weight of the poured material to the central control module 50 through a weight signal, and the central control module 50 judges whether the weight of the poured material reaches the preset weight by inversely analyzing the weight signal.

[0054] During the pouring process, the central control module 50 also receives a detection signal of the detection structure 40. When the material does not reach the position detected by the detection structure 40, the detection structure 40 sends an electric signal to the central control module 50; when the material reaches the position detected by the detection structure 40, the detection structure 40 stops sending the electric signal to the central control module 50.

[0055] The central control module 50 judges whether the container 10 is filled with the material of the preset weight based on the weight of the poured material and whether there is an electric signal. Specifically:

[0056] When there is no electric signal from the detection structure 40 and the weight of the poured material reaches the preset weight, it is determined that there is no material blocking in the container 10, and the material in the container 10 meets the filling requirement at this time.

[0057] When there is no electric signal from the detection structure 40 and the weight of the poured material does not reach the preset weight, it is determined that there is material blocking in the container 10, and the material in the container 10 is less than the preset weight, and the filling does not meet the requirement.

[0058] When the material in the container 10 meets the filling requirement, the central control module 50 sends a second start-stop signal to the fan structure 30, and the fan stops working under the instruction of the second start-stop signal. The central control module 50 also sends a second warning signal to the warning structure 60, and the warning structure 60 sends a short warning bell sound. The central control module 50 also sends a first start-stop signal to the transport structure 20, and the transport structure 20 stops pouring the material into the container 10. The operator knows that the potting is completed under the prompt of the short warning bell sound and starts the next operation.

[0059] When the material in the container 10 does not meet the filling requirement, the central control module 50 sends a first warning signal to the warning structure 60, the warning structure 60 rings for 30 seconds, the operator knows that the container 10 is blocked at this time, the central control module 50 maintains the working state of the fan structure 30, and sends a first start-stop signal to the conveying structure 20, the conveying structure 20 stops feeding the container 10, the operator clears the blockage, and after the blockage is cleared, the material falls and exposes the detection device, the detection device sends an electrical signal to the central control module 50 again, the central control module 50 sends a first start-stop signal to the conveying structure 20 again, and the conveying structure 20 continues to feed the container 10, and when the detection structure 40 stops sending an electrical signal again, it is judged whether the filled material reaches the preset weight, if the preset weight is reached, the central control module 50 sends a second start-stop signal to the fan structure 30, and the fan stops working under the instruction of the second start-stop signal. The central control module 50 also sends a second warning signal to the warning structure 60, and the warning structure 60 sends a short warning bell sound. The central control module 50 also sends a first start-stop signal to the conveying structure 20, and the conveying structure 20 stops feeding the container 10.

[0060] If the preset weight is not reached, the central control module 50 maintains the working state of the fan structure 30, and sends a first start-stop signal to the conveying structure 20, the conveying structure 20 stops feeding the container 10, the operator clears the blockage, and repeats the pot filling step again until the detection structure 40 does not send an electrical signal and the filled material reaches the preset weight.

[0061] In the application, the vibration rod sensor is used to replace the gamma ray material level switch, the operation risk is reduced, and the risk of radiation is reduced. At the same time, whether the material in the container 10 meets the filling requirement is judged by judging the weight of the conveying structure 20 and whether the vibration rod sensor has an electrical signal transmission, so that the treatment effect after filling can be ensured.

[0062] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection range of the present application.
