The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a weighing and metering tank with controllable feeding, such as... Figure 1-3 As shown, the controllable feeding weighing and metering tank includes: a mounting frame 1; a placement tank 2 mounted on the mounting frame 1, the placement tank 2 being used to store materials, the top of the placement tank 2 being provided with a feed pipe 201, the feed pipe 201 being provided with a solenoid valve, the feed pipe 201 being used to add materials into the placement tank 2; multiple connecting frames 3 fixedly mounted on the outer wall of the placement tank 2; multiple weighing sensors 4 fixedly mounted on the mounting frame 1, the multiple weighing sensors 4 being respectively connected to the multiple connecting frames 3, the weighing sensors 4 being used to weigh the materials in the placement tank 2; and a material distribution mechanism mounted on the placement tank 2, the material distribution mechanism being used to evenly distribute the materials in the placement tank 2.

[0022] It should be noted that some existing weighing and metering tanks still have certain shortcomings in actual use. When some solid materials are put into the metering tank, the materials tend to accumulate in the middle of the tank during the feeding process, while the edges of the tank are not filled with materials. The material density is inconsistent, which reduces the accuracy of weighing the materials.

[0023] In this embodiment, when adding materials to the placement tank 2, the feed pipe 201 is connected to the corresponding material pipeline. When discharging and storing some liquid materials, a controller is installed on one side of the placement tank 2. The controller opens the solenoid valve on the feed pipe 201. When adding liquid materials, the weighing sensor 4 can weigh the liquid materials entering the placement tank 2. When the required weight is reached, the controller closes the solenoid valve on the feed pipe 201, thereby stopping the addition of materials to the placement tank 2. Thus, the feeding of materials into the placement tank 2 can be controlled. When some solid materials are put into the placement tank 2, the same material pipeline is used. The material enters the placement tank 2 through the feed pipe 201. During feeding, the controller activates the material equalization mechanism, which evenly distributes the solid material in the placement tank 2, making the density of the solid material more uniform and thus improving the accuracy of weighing the solid material. Similarly, the solid material entering the placement tank 2 can be weighed through the weighing sensor 4. When the required weight is reached, the controller closes the solenoid valve on the feed pipe 201 to stop feeding the placement tank 2. Through the entire device, the material can be weighed, the feed rate can be controlled, and the density of the material can be made more uniform, thus improving the accuracy of weighing the material.

[0024] In a further preferred embodiment of the present invention, the material distribution mechanism includes: a drive motor 5 fixedly installed at the bottom of the placement tank 2; a rotating shaft 6 rotatably installed inside the placement tank 2, the rotating shaft 6 being fixedly connected to the output shaft of the drive motor 5; and a material distribution rack 7 fixedly installed on the rotating shaft 6, the material distribution rack 7 being used to distribute the material in the placement tank 2 evenly.

[0025] In this embodiment, when using the material equalization mechanism, the controller starts the drive motor 5. The running speed of the drive motor 5 can be set and controlled according to actual needs. The drive motor 5 drives the material equalization rack 7 on the rotating shaft 6 to rotate. The material equalization rack 7 stirs and spreads the material in the tank 2, making the density of the material accumulation more uniform and improving the accuracy of material weighing.

[0026] In a further preferred embodiment of the present invention, a dispersing frame 601 is fixedly installed on the top of the rotating shaft 6. The dispersing frame 601 is used to disperse the material entering the placement tank 2. A cleaning brush is fixedly installed on the material equalization frame 7. The cleaning brush is in contact with the inner wall of the placement tank 2.

[0027] In this embodiment, the material entering the placement tank 2 is dispersed by the dispersing frame 601, so that the material enters the placement tank 2 more evenly. The cleaning brush can facilitate the subsequent cleaning of the inner wall of the placement tank 2.

[0028] In a further preferred embodiment of the present invention, a connecting pipe 8 is fixedly installed at the bottom of the placement tank 2, the connecting pipe 8 is connected to the placement tank 2, a discharge pipe 9 is fixedly installed on the connecting pipe 8, the discharge pipe 9 is used to discharge the material in the placement tank 2, and an anti-blocking mechanism is provided on the connecting pipe 8.

[0029] In this embodiment, the cooperation between the connecting pipe 8 and the discharge pipe 9 facilitates the use of materials in the storage tank 2. At the same time, when solid materials are being used, the controller activates the anti-blocking mechanism to move the solid materials in the connecting pipe 8, thereby preventing blockages during the material feeding process.

[0030] In a further preferred embodiment of the present invention, the anti-blocking mechanism includes: a servo motor 10 fixedly installed on the connecting pipe 8; a mounting shaft 11 rotatably installed inside the connecting pipe 8, one end of the mounting shaft 11 being fixedly connected to the output shaft of the servo motor 10; and a plurality of material-pulling rods 12 fixedly installed on the mounting shaft 11, the material-pulling rods 12 being used to poke the material inside the connecting pipe 8.

[0031] In this embodiment, when using the anti-blocking mechanism, the controller starts the servo motor 10 to drive the material-pushing rod 12 on the mounting shaft 11 to rotate. The rotating material-pushing rod 12 pushes the material in the connecting pipe 8, thereby preventing blockage during the feeding process.

[0032] In a further preferred embodiment of the present invention, the placement tank 2 is provided with a discharge mechanism, which is used to discharge the material in the placement tank 2. The discharge mechanism includes: a booster pump 13 fixedly installed on the outer wall of the placement tank 2; and a bent pipe 14 fixedly installed on the placement tank 2, wherein the bent pipe 14 is connected to the booster pump 13.

[0033] In this embodiment, when discharging liquid material, the controller starts the booster pump 13, which, with the cooperation of the bend 14, can pressurize the place tank 2, thereby accelerating the discharge speed of the liquid material in the place tank 2.

[0034] In a further preferred embodiment of the present invention, both the bend 14 and the discharge pipe 9 are provided with control valves, and the two control valves are respectively used to control the bend 14 and the discharge pipe 9.

[0035] In this embodiment, a control valve is used to control the operation of the bend 14 and the discharge pipe 9.

The temperature and humidity sensor 15 is used to monitor the temperature and humidity inside the placement tank 2, and the pressure sensor 16 is used to monitor the pressure inside the placement tank 2.

[0037] In this embodiment, a temperature and humidity sensor 15 is used to monitor the temperature and humidity inside the placement tank 2, a pressure sensor 16 is used to monitor the pressure inside the placement tank 2, and a pressure relief valve is provided on the placement tank 2.
