Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically to an automatic metering and mixing device for multiple raw materials. Background Technology

[0002] A raw material metering device is a system used to accurately measure the quantity of various production raw materials. It collects the physical parameters of the raw materials through sensors, processes them through a control system, and converts them into specific metering values, enabling real-time monitoring and recording of raw material input and inventory levels. This device is widely used in industries such as chemical, food, and building materials.

[0003] Current raw material metering devices exhibit several significant limitations in long-term use. After a period of operation, frequent manual feeding is often required, increasing the workload of operators and making it difficult to accurately control the feeding amount each time. This can easily lead to unstable raw material supply due to human error. More importantly, splashing of reagents frequently occurs during the metering and discharging process. This not only wastes raw materials but also directly affects the accuracy of the final metering results, causing a discrepancy between the actual quantity of reagent obtained and the theoretical value. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes an automatic metering and mixing device for multiple raw materials that can automatically feed materials, accurately control the feeding amount, reduce splashing of the discharged medicine, and minimize data errors.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: an automatic metering and mixing device for multiple raw materials, comprising:

[0006] The support includes an upper plate, a lower plate, and several support rods. The upper plate is located above the lower plate and parallel to the lower plate, and has a through hole in its center. The support rods are fixedly located between the upper plate and the lower plate. A weighing scale is fixedly mounted on the lower plate, and several support feet are provided on the bottom surface.

[0007] The mixing container is placed on the weighing scale;

[0008] The raw material tank is fixed on the upper plate by a bracket. A feeding pipe is provided on the upper wall, and a feeding valve is provided on the feeding pipe. A discharge pipe is provided at the lower end of the side wall, and a discharge valve and a flow meter are provided on the discharge pipe. Its lower end extends into the through hole. A liquid level sensor is provided on the side wall of the raw material tank.

[0009] The flow guide is fixedly installed below the through hole on the upper plate and directly above the mixing tank.

[0010] Furthermore, the support rod and the support leg are equidistantly arranged along the edge of the lower plate, and the bottom surface of the support leg is provided with an anti-slip pad.

[0011] Furthermore, the mixing tank is provided with several handles at equal intervals on its side wall.

[0012] Furthermore, a pressure balancing port is provided on the upper wall of the raw material tank.

[0013] Furthermore, the liquid level sensor includes an upper limit liquid level sensor near the top of the raw material tank and a lower limit liquid level sensor near the bottom of the raw material tank.

[0014] Furthermore, the flow guide is a frustum-shaped structure with an upper port diameter larger than the lower port diameter.

[0015] Compared with existing technologies, the advantages of this invention are as follows: The discharge pipe of the raw material tank is equipped with a flow meter and a valve, which can monitor the discharge volume in real time. Combined with the real-time feedback of the raw material quantity from the liquid level sensor, the valve opening and closing can be precisely adjusted to control the feeding volume. A frustum-shaped guide shield is located below the raw material tank, which guides the raw material precisely into the mixing tank, reducing spillage and splashing. Simultaneously, the mixing tank is placed on a weighing scale, allowing for a second weighing of the total raw material weight. This dual weighing reduces data errors and makes the mixing ratio more accurate. The pressure balancing port also helps to ensure a stable flow of raw material, further guaranteeing the accuracy of the measurement. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4An automatic metering and mixing device for multiple raw materials includes: a support frame, comprising an upper plate 1, a lower plate 2, and several support rods 3. The upper plate 1 is positioned above and parallel to the lower plate 2, and has a through hole in its center. The support rods 3 are fixedly positioned between the upper plate 1 and the lower plate 2. A weighing scale 4 is fixedly mounted on the lower plate 2, and several support feet 5 are provided on the bottom surface. The support rods 3 and support feet 5 are equidistantly arranged along the edge of the lower plate 2. The bottom surface of the support feet 5 is provided with anti-slip pads, which can make the support frame more evenly stressed and improve the overall stability. The anti-slip pads can increase friction and prevent the device from sliding during operation.

[0023] Combined with appendix Figure 1 The mixing tank 6 is placed on the weighing scale 4. Several handles 15 are provided at equal intervals on the side wall of the mixing tank 6, which makes it convenient for operators to carry and move the mixing tank, especially when transferring materials after mixing is completed.

[0024] Combined with appendix Figure 1 Appendix Figure 2 The raw material tank 7 is fixed on the upper plate 1 by the bracket 8. The upper wall is provided with a feeding pipe 9, and the feeding pipe 9 is provided with a feeding valve 10. The lower end of the side wall is provided with a discharge pipe 11, and the discharge pipe 11 is provided with a discharge valve 12 and a flow meter 13. Its lower end extends into the through hole. The upper wall of the raw material tank 7 is provided with a pressure balance port 16, which can balance the air pressure inside and outside the tank to ensure that the raw material is discharged smoothly and avoid the discharge obstruction caused by the air pressure imbalance.

[0025] Combined with appendix Figure 3 Appendix Figure 4 The raw material tank 7 is equipped with a liquid level sensor on its side wall. The liquid level sensor includes an upper limit liquid level sensor 17 near the upper end of the raw material tank 7 and a lower limit liquid level sensor 18 near the lower end of the raw material tank 7. It can monitor the liquid level in the raw material tank 7 in real time, and promptly remind the user to add or stop feeding to ensure a stable supply of raw materials.

[0026] Combined with appendix Figure 3 Appendix Figure 4 The flow guide shroud 14 is fixedly installed below the through hole on the upper plate 1 and directly above the mixing tank 6. The flow guide shroud 14 is a frustum-shaped structure with an upper port diameter larger than the lower port diameter, which can more accurately guide the raw materials into the mixing tank 6, reduce raw material spillage, and improve raw material utilization.

[0027] The specific implementation of this utility model is as follows: Connect the device to an external power source. Add raw materials to each raw material tank 7 through the feeding pipe 9. Open the feeding valve 10 until it is triggered by the upper limit liquid level sensor 17, then close it. Place the mixing tank 6 on the weighing scale 4, ensuring it is directly below the guide shroud 14. Open the discharge valve 12 of the raw material tank 7, and the raw materials flow out through the discharge pipe 11. The flow meter 13 monitors the flow rate in real time, and, combined with the information from the upper limit liquid level sensor 17 and the lower limit liquid level sensor 18, accurately controls the discharge amount. The raw materials are introduced into the mixing tank 6 through the guide shroud 14, and the pressure balancing port 16 balances the air pressure to ensure smooth discharge. When the amount of raw materials reaches the set value, the discharge valve 12 automatically closes. After multiple raw materials are fed in sequence, the weighing scale 4 verifies the total weight of the materials in the mixing tank 6 a second time. After mixing is complete, the operator holds the handle 15 and removes the mixing tank 6 from the weighing scale 4. If the raw material in the raw material tank 7 is lower than the lower limit liquid level sensor 18, the system will remind the operator to replenish the material through the feeding pipe 9 to ensure sufficient raw materials for the next use.
