[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Example 1

[0028] Please refer to Figure 1-5 As a specific implementation, this utility model provides a modified storage tank 2 discharge device, including a storage tank 2 and a homogenizing mixing tank 1 disposed above the storage tank 2. The homogenizing mixing tank 1 is provided with a discharge channel 10 communicating with the storage tank 2, and further includes:

[0029] The first air inlet 31 is provided on at least one side wall of the feeding channel 10 and is connected to the air source 3;

[0030] The exhaust duct 33 is installed on the storage tank 2 to connect the interior of the storage tank 2 with the atmosphere;

[0031] Control valve 34 is installed on the air duct 33.

[0032] Specifically, it should be noted that the storage tank 2 is vertically arranged, and a homogenizing mixing tank 1 is arranged above the storage tank 2. A connecting pipe 20 is arranged at the top of the storage tank 2, and a funnel is arranged at the bottom of the homogenizing mixing tank 1. The feeding channel 10 is the funnel, and the lower end 330 is the feeding port 101, which is connected to the connecting pipe 20. In some embodiments, a switch valve is arranged between the connecting pipe 20 and the feeding port 101 to open and close the feeding port 101. The above structure and connection method are all existing mature structures, and their specific structures will not be described in detail here. The improvement of this application is that a first air port 31 is arranged on the side wall of the funnel, and an air pipe is arranged at the first air port 31. The 310 connector connects to the air pipe 310, which is connected to the air source 3 via the first air supply line 320. An exhaust pipe 33 is installed at the top of the storage tank 2, and a control valve 34 is installed on the exhaust pipe 33. When it is necessary to discharge material downwards, gas is supplied to the first air port 31 through the air source 3. The gas can blow the discharge port 101 and open the control valve 34 at the same time, which facilitates the discharge of gas inside the storage tank 2, thereby increasing the material discharge speed. According to statistics, the time for discharging one ton of material downwards using the above method is about 8 minutes, which is nearly 4 times shorter than the previous 30 minutes, greatly improving the material discharge efficiency and improving the operation efficiency.

[0033] Specifically, the air source 3 can be a compressed air tank or a compressed air pump, and the control valve 34 can be any type of manually controlled ball valve, plate valve, etc.

[0034] Furthermore, the first air port 31 can be connected to the air tube 310 using a C-type quick-connect fitting, improving the ease of connection.

[0035] Furthermore, as a preferred embodiment, the first air inlet 31 is inclined downwards. Specifically, when configured, the first air inlet 31 is inclined downwards, which can guide the airflow downwards, making it easier for the material to fall from the feeding channel 10 and achieving a better feeding effect.

[0036] Furthermore, it is understood that an exhaust duct 33 is installed on the storage tank 2, and a control valve 34 is installed on the exhaust duct 33. When the control valve 34 is closed, the storage tank 2 is in a closed state. At this time, the direction of the control valve 34 away from the storage tank 2 may accumulate dust and other impurities, especially when the outlet of the exhaust duct 33 is facing upwards. In this case, when the control valve 34 is opened, the impurities may fall into the storage tank 2 below. In order to reduce the probability of the above phenomenon occurring, as a preferred embodiment, refer to... Figures 1-4 The side wall of the air duct 33 is also provided with a second air port 35, which is connected to the air source 3 and is located on the side of the control valve 34 near the storage tank 2.

[0037] Specifically, by setting a second air port 35 on the side wall of the exhaust duct 33, and connecting the second air port 35 to the air source 3, the air source 3 supplies air to the second air port 35 before opening the control valve 34, so that the exhaust duct 33 has a certain air pressure. Then the control valve 34 is opened. When the control valve 34 is opened, the gas inside the exhaust duct 33 flows outward, thereby discharging the impurities accumulated on the control valve 34 and effectively reducing the above phenomenon. After the control valve 34 is opened, the control air source 3 continues to supply air to the second air port 35 for 2-3 seconds, and then stops supplying air. The control air source 3 then supplies air to the first air port 31, and the material in the homogenizing mixing tank 1 is discharged downward.

[0038] Furthermore, as a preferred embodiment, refer to Figure 2 In some embodiments, an elbow 340 is provided at the upper end of the air duct 33, which bends downward, thereby effectively preventing impurities from falling into the air duct 33. Also, in some embodiments, a control valve 34 can be provided on the downward bend of the elbow 340 to achieve a better protective effect.

[0039] Furthermore, as a specific implementation method, refer to Figure 1 A first solenoid valve 321 is installed between the first air port 31 and the air source 3, and a second solenoid valve 351 is installed between the second air port 35 and the air source 3. Specifically, the first air port 31 is connected to the air source 3 through a first air supply pipe 310, and the first solenoid valve 321 is installed between the air source 3 and the first air port 31. The second air port 35 is connected to the air source 3 through a second air supply pipe 350, and the second solenoid valve 351 is installed on the second air supply pipe 350. Both the first solenoid valve 321 and the second solenoid valve 351 are connected to the control device 4. During operation, the control device 4 can control the opening and closing of the first solenoid valve 321 and the second solenoid valve 351 sequentially. First, the second solenoid valve 351 is opened, then the control valve 34 is opened. The control valve 34 is open, and the second solenoid valve 351 remains open for 2-3 seconds, then closes. Then, the first solenoid valve 321 is opened to start discharging material.

[0040] Furthermore, as a preferred embodiment, the control valve 34 is an electrically controlled valve. The control valve 34 is also connected to the control device 4 and is uniformly controlled by the control device 4 to open the second solenoid valve 351, the control valve 34, and the first solenoid valve 321 in sequence, which is conducive to automated operation. It should be noted that the control method of controlling the electrically controlled valves to open sequentially according to the time interval is a conventional control method in the art. The control device 4 here adopts the existing technology and is not limited to it. Any existing technology that can achieve the above control requirements is acceptable. The specific structure and working method of the control device 4 will not be described in detail here, and those skilled in the art should understand.

[0041] Furthermore, the gas source 3 is connected to a main pipeline 320; when at least two first gas ports 31 are provided, each is connected to the other end of the main pipeline 320, and the first solenoid valve 321 is disposed on the main pipeline 320. As a preferred embodiment, refer to... Figure 1 To ensure better material discharge effect, two or more first air ports 31 can be set and spaced around the material discharge channel 10. When there are two or more first air ports 31, for easy control, the first air supply pipeline 320 connected to each first air port 31 is connected to the main pipeline 320. The first solenoid valve 321 is set on the main pipeline 320. In this way, two or more first air ports 31 can be controlled by one first solenoid valve 321.

[0042] Example 2

[0043] Specifically, it is understandable that although the interior of storage tank 2 is sealed, when the material inside storage tank 2 is too low, the interior becomes a cavity. When the second solenoid valve 351 supplies air to the second air port 35, the gas inside storage tank 2 is compressible. Therefore, when air is supplied through the second air port 35, the airflow will flow into the interior of storage tank 2, resulting in insufficient air pressure in the drainage pipe. At this time, when the control valve 34 is opened, the outflow velocity of the airflow is low, affecting the impurity cleaning effect. As a preferred embodiment, please refer to... Figures 5-7 As a specific implementation method, this utility model provides a modified storage tank 2 discharge device, which differs from the first embodiment in that the air duct 33 extends into the lower end 330 of the storage tank 2 and is connected to a valve body assembly 36. The valve body assembly 36 is configured to switch from a first state to a second state when the second air port 35 is connected to the air source 3. The flow area of ​​the valve body assembly 36 in the first state is greater than the flow area in the second state.

[0044] For details, please refer to Figure 6 This is a schematic diagram showing the state of valve body assembly 36 in its first state. Figure 7This is a schematic diagram of the valve body assembly 36 in the second state. With the above settings, when the second solenoid valve 351 is closed, the air pressure inside the exhaust pipe 33 is low and there is no airflow. At this time, the valve body assembly 36 remains in the initial first state. When the second solenoid valve 351 is opened, compressed gas is delivered into the exhaust pipe 33. When the control valve 34 is closed, the compressed gas flows into the storage tank 2. Under the action of the airflow, the valve body assembly 36 switches states, reducing the flow area. The reduced flow area can effectively reduce the flow rate of gas flowing into the storage tank 2 from the exhaust pipe 33, which is conducive to the increase of air pressure in the exhaust pipe 33. This ensures that the flow rate of gas flowing out of the control valve 34 is guaranteed when the control valve 34 is opened, thus ensuring the cleaning effect. After the control valve 34 is opened, the second solenoid valve 351 is closed. At this time, the compressed gas in the storage tank 2 flows out through the exhaust pipe 33, and the valve body assembly 36 returns to the first state, which is conducive to the discharge of airflow.

[0045] Furthermore, as a specific implementation method, refer to Figure 6 , Figure 7 The specific structure of the valve body assembly 36 is as follows: The valve body assembly 36 includes:

[0046] The upper end of the rectangular cylinder 360 is connected to the lower end 330 of the air duct 33;

[0047] At least one valve plate 362 is provided, with one end rotatably mounted inside a rectangular cylinder 360 via a shaft 361. The shaft 361 extends along the edge of the rectangular cylinder 360, and an elastic element is provided between the valve plate 362 and the rectangular cylinder 360.

[0048] Specifically, a rectangular cylinder 360 is welded to the lower end 330 of the air duct 33, and its upper end is sealed to the side wall of the air duct 33. After connection, a limiting part 364 is formed in the junction area. Two shafts 361 are rotatably inserted through the opposite side wall of the rectangular cylinder 360. Specifically, the shafts 361 are rotatably engaged with the rectangular cylinder 360, and a valve plate 362 is sleeved on the shafts 361. The valve plate 362 is non-rotatably engaged with the shafts 361. A torsion spring (not shown on the coaxial 361) is provided between the shafts 361 and the rectangular cylinder 360. The torsion spring provides elastic force to keep the valve plate 362 in the first state. In the first state, the valve plate 362 abuts against the limiting part 364. The valve plate 362 includes a flow-facing section above the limiting part 364. By forming the flow-facing section, when air is vented into the air duct 33 to generate airflow into the storage tank 2, it is more conducive to pushing the flow-facing section to push the valve plate 362 to switch states. With the above arrangement, when the valve plate 362 rotates, the area of ​​the flow surface of the rectangular cylinder 360 can be increased, thereby reducing the flow area.

[0049] Furthermore, two shafts 361 and two valve plates 362 are provided. On the two side walls of the rectangular cylinder 360 that are rotatably engaged with the shaft 361, a limiting plate 363 is provided. By setting the limiting plate 363, the valve plate 362 can be limited. When the limiting plate 363 is in contact with the valve plate 362, the plate surface of the valve plate 362 is perpendicular to the axis 361 line of the rectangular cylinder 360. At this time, the blocking effect is the best, which is the second state.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
