Description

Technical Field

[0001] The present invention relates to the technical field of solid and liquid material addition and mixing, and particularly relates to an automatic quantitative addition device for solid-liquid materials. Background Art

[0002] Currently, in industries such as chemical engineering, environmental protection, and construction, most working conditions require adding solid materials or liquid materials to a base liquid. For example, in the process of chemical production, many chemical reactions require specific solid or liquid catalysts, reactants, or additives to initiate or promote the reaction. Therefore, it is often necessary to mix or process solid and liquid materials in a certain proportion or specific quantity.

[0003] In the prior art when adding solid materials or liquid materials, the solid materials are generally directly discharged into the mixing unit and mixed with the base liquid after the bags are broken. During mixing, problems such as dust splashing, inaccurate determination of the addition amount, discontinuous addition, and uneven mixing are likely to occur. Moreover, the manual bag-breaking efficiency is low. Especially, since solid materials are generally in powder form, it is easy to cause personal injury to operators. Liquid materials are generally directly poured from the material barrel into the mixing unit to adjust the performance of the base liquid, but the addition amount is not controlled, which is likely to cause material waste. Especially, since liquid materials generally have corrosiveness, it also causes personal injury to operators. Therefore, it is necessary to automatically and quantitatively add solid and liquid materials to improve operation efficiency, reduce production costs, ensure personnel safety, and meet the HSE environmental protection requirements.

[0004] Therefore, it is necessary to propose an automatic quantitative addition device for solid-liquid materials to overcome the defects of discontinuous and inaccurate addition of solid and liquid materials in the prior art. Summary of the Invention

The buffer tank is located at the bottom of the solid storage tank. A flexible connection unit is provided between the buffer tank and the solid storage tank. Weighing sensors are provided on both the solid storage tank and the buffer tank.

[0007] Further, the weighing sensor includes a compressive stress weighing sensor and a tensile stress weighing sensor. The compressive stress weighing sensor is located between the solid storage tank and the overall skid base, and the tensile stress weighing sensor is located between the buffer tank and the overall skid base.

[0008] Further, an air control unit is also installed on the overall skid base. The air control unit includes an air storage tank and an air pipeline fixedly connected to the air storage tank. Both the solid storage tank and the buffer tank are connected to the air pipeline.

[0009] Further, the mixing and delivery unit includes a delivery pump and a mixing funnel. The mixing funnel is installed at the bottom of the discharger.

DETAILED DESCRIPTION OF THE INVENTION

[0019] In order to make the technical means, technical features, invention purpose and technical effects achieved by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0020] Embodiment 1: As Figure 1 shown, this embodiment provides an automatic quantitative addition device for solid-liquid materials, including an integral skid base 3. A solid material addition unit 1, a liquid material addition unit 2, a pneumatic control unit 5 and an automatic control unit 4 are installed on the integral skid base 3. The integral skid base 3 is an important structural support component. Each unit is combined into an independent module, which is convenient for hoisting and transportation. The automatic control unit 4 is electrically connected to the solid material addition unit 1, the liquid material addition unit 2 and the mixing and conveying unit. The automatic control unit 4 can control the operation of the equipment and the actions of each valve, so as to realize the quantitative addition and mixing and conveying of solid-liquid materials.

[0021] As Figure 3 and Figure 5 shown, the solid material addition unit 1 includes a solid storage tank 10, a buffer tank 14 and a discharger 16. The solid storage tank 10 and the buffer tank 14 are installed on the integral skid base 3 by screws. The buffer tank 14 is located at the bottom of the solid storage tank 10. Weighing sensors are provided on both the solid storage tank 10 and the buffer tank 14. The weighing sensors can monitor the addition amount of solid materials. The weighing sensors include a compressive stress weighing sensor 12 and a tensile stress weighing sensor 13. The compressive stress weighing sensor 12 is located between the solid storage tank 10 and the integral skid base 3 and can weigh the materials in the solid storage tank 10. The tensile stress weighing sensor 13 is located between the buffer tank 14 and the integral skid base 3 and can weigh the materials in the buffer tank 14. When solid materials need to be added, the value on the compressive stress weighing sensor 12 is the initial value. At this time, the solid materials enter the buffer tank 14 from the solid storage tank 10 until the value on the compressive stress weighing sensor 12 reaches the set value; at the same time, the value on the tensile stress weighing sensor 13 also changes with the addition of solid materials in the buffer tank 14. Therefore, through the change of the readings of the compressive stress weighing sensor 12 and the tensile stress weighing sensor 13, the addition amount of solid materials can be measured more accurately.

[0022] As Figure 3 and Figure 5As shown, a flexible connection unit 11 is provided between the buffer tank 14 and the solid storage tank 10. The flexible connection unit 11 is preferably a flexible pipe, which serves to guide the material and prevent material leakage, thus ensuring the enclosed addition of the material. The discharger 16 is installed at the bottom of the buffer tank 14 by screws. The discharger 16 cooperates with a weighing sensor to control the addition amount of the solid material. The discharger 16 is preferably a star discharger 16. Each time the star discharger 16 rotates one week, a certain amount of solid material drops. By recording the number of rotations of the star discharger 16, the addition amount of the solid material can be determined. Electrically operated gate valves 15 are fixedly installed by screws between the buffer tank 14 and the solid storage tank 10, and between the buffer tank 14 and the discharger 16. The electrically operated gate valves 15 can be quickly opened and closed to achieve automatic control of the drug addition. The solid material addition unit 1 has two sets of addition devices that can work independently. The devices can work independently or be used as backups for each other to ensure that the normal use of the system is not affected when a certain device has problems. Each solid storage tank 10 stores a kind of solid material and can be replaced according to needs.

[0023] As Figure 2 and Figure 4 shown, a mixing and conveying unit is installed at the bottom of the discharger 16. The mixing and conveying unit includes a transfer pump 18 and a mixing funnel 17. The mixing funnel 17 is installed at the bottom of the discharger 16 by screws. A mixing funnel discharge pipeline 194 is screwed to the mixing funnel 17. A mixing funnel discharge port 195 is welded on the mixing funnel discharge pipeline 194. The transfer pump 18 is connected to the overall skid base 3 by screws. A pump suction pipeline 191 and a pump discharge pipeline 192 are screwed to the transfer pump 18. The pump suction pipeline 191 communicates with an external mixing unit. The pump discharge pipeline 192 is connected to the mixing funnel 17 by screws. A pump suction port 193 is welded on the pump suction pipeline 191. The transfer pump 18 sucks the base liquid from the external mixing unit through the pump suction port 193 into the pump suction pipeline 191, and then discharges it into the mixing funnel 17 through the pump discharge pipeline 192. After the solid and liquid materials are added, they are discharged into the external mixing unit through the mixing funnel discharge pipeline 194, thus completing the mixing and conveying of the solid and liquid drugs.

[0024] As Figure 6 and Figure 7As shown in the figure, the liquid material adding unit 2 includes a liquid material bucket 20 and a pump 21. The liquid material bucket 20 is connected to the overall skid base 3 by screws. The suction end of the pump 21 is connected to the liquid material bucket 20 by screws. A delivery pipeline 24 is connected to the discharge end of the pump 21 by screws. The delivery pipeline 24 includes a shunt pipeline 241 and a liquid inlet pipeline 242. The liquid inlet pipeline 242 is connected to the mixing funnel 17 by screws. The shunt pipeline 241 is located between the pump 21 and the liquid inlet pipeline 242. Flow sensors 23 are fixedly connected to both the shunt pipeline 241 and the liquid inlet pipeline 242 by screws. The pump 21 is preferably a pneumatic diaphragm pump 21. The pneumatic diaphragm pump 21 adds the liquid material in the liquid material bucket 20 to the feeding funnel through the shunt pipeline 241 and the liquid inlet pipeline 242. During the adding process, the flow sensor 23 can accurately measure the amount of the added liquid medicine. A liquid level gauge and a flow sensor 23 are fixedly connected to the outlet of the liquid material bucket 20 by screws. By cooperating with the liquid level gauge and the flow sensor 23, the volume of the liquid material in the liquid material bucket 20 can be monitored. An electric valve 22 is fixedly connected to the liquid material bucket 20 by screws. By switching the electric valve 22, the addition of the liquid material can be realized. Since the pump 21 is likely to suck air when sucking the liquid, by setting the liquid level gauge and the electric valve 22, when the liquid in the liquid material bucket 20 reaches the lowest level, the electric valve 22 is instantaneously closed to prevent the pump 21 from sucking air. A plurality of liquid material buckets 20 are provided, and each liquid material bucket 20 stores a kind of liquid material, which can be replaced according to needs.

[0025] As Figure 1 shown in the figure, the pneumatic control unit 5 includes an air storage tank and an air pipeline connected to the air storage tank by screws. Both the solid storage tank 10 and the buffer tank 14 are connected to the air pipeline by screws. The pneumatic control unit 5 supplies air to the solid storage tank 10 and the buffer tank 14 through the air pipeline to fluidize the solid material, so that the solid material can smoothly fall into the discharger 16, facilitating the feeding and preventing the material from caking.

[0026] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made to the content within the scope of the patent application of the present invention shall fall within the technical scope of the present invention.
