Description

Technical Field

[0001] The present application relates to the technical field of batching, and in particular to a high-precision batching device using a loss-in-weight method. Background Art

[0002] Batching technology is a core process in the food, chemical, and pharmaceutical industries. It refers to a system that combines multiple raw materials in precise proportions and optimizes the processing flow based on the functional requirements of different products. Its core components include raw material screening, ratio calculation, mixing homogenization, and stability control, requiring dynamic adjustments based on physical property analysis and process parameters.

[0003] Currently, when batching multiple raw materials, they are stored separately in multiple storage tanks fixed to a bracket. Each tank is connected to a batching valve via a pipe, and multiple batching valves surround the outer periphery of the tank. During the batching process, a moving mechanism drives a batching valve to move above the batching port. Once the batching valve is opened, a single raw material can be batched. The moving mechanism then drives the previous batching valve to reset, and then drives the next batching valve to move above the batching port to batch the raw materials. This process can be repeated multiple times to complete the batching of multiple raw materials.

[0004] The bracket, mobile mechanism, multiple storage tanks, pipelines and batching valves take up a lot of space, making the batching device larger, inconvenient to transport and assemble the batching device, and also inconvenient to inspect and maintain the batching device.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0036] The embodiment of the present application discloses a high-precision batching device using a loss-in-weight method.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 A high-precision weight-loss batching device includes a batching tank 1, with a pneumatic flange ball valve 14 fixedly mounted on one side of the top of the batching tank 1. The top of the pneumatic flange ball valve 14 is formed with a batching port 2. A bottom plate 9 is mounted on one side of the diameter of the batching tank 1. The bottom plate 9 is placed on an external support frame or fixed to the outer wall of the batching tank 1.

[0038] Two second guide rails 10 are fixedly mounted on the top wall of the base plate 9. Two second sliders 11 are slidably mounted on each second guide rail 10. A bracket 3 is fixedly mounted on the four second sliders 11. A sector-shaped support plate 15 is fixedly mounted on the top of the bracket 3. The dispensing port 2 at the top of the pneumatic flange ball valve 14 is located at the center of the sector-shaped support plate 15.

[0039] A micro switch 19 is fixedly mounted on the base plate 9, and the bracket 3 is driven to move by an external driving structure. When the bracket 3 moves to a designated location, the bracket 3 moves to contact the micro switch 19, and the micro switch 19 then closes the external driving structure through the controller, thereby positioning the movement of the bracket 3.

[0040] Two sockets 12 are fixedly installed on the bottom plate 9, and two pins 13 are slidably installed in the bracket 3 along the vertical direction. When the bracket 3 stops moving, the pins 13 are slid into the sockets 12 to fix the bracket 3 and prevent the bracket 3 from sliding.

[0041] Reference Figure 3 and Figure 4 Eight dispensing mechanisms 4 are mounted on the top wall of the support plate 15. These are arranged in a sector shape along the circumference of the dispensing port 2, and each dispensing mechanism 4 is slidably mounted along the diameter of the dispensing port 2. Within the circumference above the dispensing port 2, a sector-shaped avoidance zone 5 is formed on the other side of the eight dispensing mechanisms 4. This avoidance zone 5 avoids the drive motor in the middle of the top wall of the dispensing tank 1.

[0042] During the batching operation, multiple raw materials are stored in multiple batching mechanisms 4. When batching, the batching mechanism 4 slides to the top of the batching port 2 to perform the batching operation. After the multiple batching mechanisms 4 complete the movement of the batching in sequence, the batching task of multiple raw materials can be completed.

[0043] The eight batching mechanisms 4 are arranged in a fan-shaped pattern. This arrangement allows the avoidance area 5 on the other side of the eight batching mechanisms 4 to avoid the drive motor on the batching tank 1. This design reduces the size of the batching device, making it more convenient to transport, assemble, and repair and maintain.

[0044] Reference Figure 3 、 Figure 4 and Figure 5 Specifically, the dispensing mechanism 4 includes a storage tank 41, a dispensing valve 42, a weighing device 43, and a moving assembly 44. The moving assembly 44 is mounted on the support plate 15. The support block 16 is fixedly mounted on the moving end of the moving assembly 44. The weighing device 43 is fixedly mounted on the support block 16. The storage tank 41 is fixedly mounted on the weighing device 43. The dispensing valve 42 is mounted on the side of the storage tank 41 near the dispensing port 2. In this application, the weighing device 43 can be a Mettler load cell.

[0045] Raw materials are stored in a storage tank 41. When batching is required, a moving assembly 44 drives the storage tank 41 toward the batching port 2. When the storage tank 41 moves the batching valve 42 directly above the batching port 2, the valve 42 opens and batching begins. During this process, a scale 43 measures the weight of the storage tank 41 in real time, enabling precise batching.

[0046] Eight pads 18 are fixedly installed on the support plate 15 at circumferential intervals along the dosing port 2. Each pad 18 is installed radially along the dosing port 2. A support arc plate 20 is fixedly installed at one end of the eight pads 18 away from the dosing port 2, and each moving component 44 is installed on a pad 18.

[0047] The moving assembly 44 is composed of a first guide rail 441, a first slider 442 and a second driving member 443. The first guide rail 441 is fixedly mounted on the pad 18, the first slider 442 is slidably mounted on the first guide rail 441, the support block 16 is fixedly mounted on the first slider 442, and the base of the second driving member 443 is fixed on the pad 18, and its driving end is fixedly connected to the support block 16. In the present application, the second driving member 443 can be optionally used as a cylinder. When the second driving member 443 is started, the output thrust drives the first slider 442 to perform linear displacement along the first guide rail 441, synchronously driving the weighing device 43 and the storage tank 41 to translate as a whole, and the storage tank 41 then drives the dosing valve 42 to move to just above the dosing port 2.

[0048] The storage tank 41 consists of an integrally formed first tank body 411 and a second tank body 412. The first tank body 411 is fixedly mounted on the weighing device 43 via a support 17 and has a fan-shaped top view. The second tank body 412 is located on the side of the first tank body 411 near the dispensing port 2 and has a rectangular top view. The first tank body 411 and the second tank body 412 are interconnected, and the axis of symmetry of the first and second tank bodies 411, 412, when viewed from above, is arranged along the diameter of the dispensing port 2. The dispensing valve 42 is mounted at the end of the second tank body 412, adjacent to the dispensing port 2.

[0049] The first tank body 411 and the second tank body 412 are designed in a shape structure which, under the premise of ensuring that the storage tank 41 has a large internal capacity, effectively avoids collision with other storage tanks 41 when the moving assembly 44 drives the first tank body 411 and the second tank body 412 and the dosing valve 42 to move.

[0050] The storage tank 41 adopts an inclined bottom wall design, and the bottom of the first tank body 411 and the second tank body 412 close to the first tank body 411 gradually inclines upward from the position adjacent to the dosing port 2 in the direction away from it. The top of the first tank body 411 is provided with a third driving member 6, and the output shaft of the third driving member 6 extends into the storage tank 41 and is connected with a stirring blade 7.

[0051] During the waiting for dosing process, the third driving member 6 continuously drives the stirring blade 7 to rotate, avoiding the particles in the raw materials from settling or caking due to static. At the same time, the inclined bottom wall of the storage tank 41 forms a one-way flow guide slope, which not only improves the flowability of the raw materials in cooperation with the stirring action, but also guides the residual raw materials to collect on the low side during the cleaning stage, significantly reducing the adhesion of residual materials on the tank wall and achieving rapid and thorough cleaning.

[0052] The dosing valve 42 includes a first driving member 421, a valve stem 422, a valve seat 423, and a plug 424. The first driving member 421 is fixedly installed on the top of the second tank body 412 away from the first tank body 411. The driving end of the first driving member 421 is fixedly connected with the top end of the valve stem 422, and the valve stem 422 linearly slides in the vertical direction. In this application, the first driving member 421 can be selected as a pneumatic cylinder. The valve seat 423 is fixedly embedded in the lowest point of the inclined bottom wall of the second tank body 412 (adjacent to the dosing port 2), and the plug 424 is threadedly locked at the bottom end of the valve stem 422 and accurately aligned with the center line of the valve seat 423.

[0053] When the valve needs to be opened, the first driving member 421 drives the valve stem 422 to move upward, so that the plug 424 is completely separated from the sealing surface of the valve seat 423, and the raw materials flow into the dosing port 2 through the valve seat 423; when the valve needs to be closed, the first driving member 421 pushes the valve stem 422 downward to press the valve seat 423 with the plug 424, so as to close the dosing valve 42 and achieve zero leakage cutoff.

[0054] A recovery ring 8 is coaxially installed outside the top dosing port 2 of the pneumatic flange ball valve 14, and the recovery ring 8 is fixedly connected with the top of the pneumatic flange ball valve 14 by bolts, and the recovery ring 8 is located below the eight dosing valves 42. When the dosing valve 42 leaks, the leaked raw materials are intercepted by the recovery ring 8, reducing the raw material dripping rate and eliminating the scaling phenomenon around the dosing port 2.

[0055] The implementation principle of the high-precision batching device according to an embodiment of the present application is as follows: during the batching operation, a plurality of raw materials are respectively stored in a plurality of batching mechanisms 4. During batching, the second driving member 443 is started and outputs a thrust force to drive the first sliding block 442 to perform linear displacement along the first guide rail 441, synchronously driving the whole weighing device 43 and the storage tank 41 to translate, and the storage tank 41 drives the batching valve 42 to move to the directly above the batching port 2. The first driving member 421 drives the valve rod 422 to displace upward, so that the plug 424 is completely separated from the sealing surface of the valve seat 423, and the raw material in the storage tank 41 flows into the batching port 2 through the valve seat 423. After the plurality of batching mechanisms 4 complete the movement and batching in sequence, the batching task of the plurality of raw materials can be realized. The eight batching mechanisms 4 are arranged in a fan shape, and this layout enables the avoidance area 5 on the other side of the eight batching mechanisms 4 to avoid the driving motor on the batching tank 1. Through this design, the volume of the batching device is reduced, and the convenience in transportation, assembly, maintenance and other aspects is further improved.

[0056] The above is only an optional embodiment of the present application, and is not used to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
