Description

Technical Field

[0001] This invention belongs to the field of graphite processing technology, specifically an automatic graphite concentration proportioning device and proportioning method. Background Technology

[0002] In the forging industry, the forging process requires the use of diluted graphite to lubricate the mold in order to facilitate the successful demolding of the forging. Traditional graphite dilution methods involve manual mixing, requiring workers to manually add a certain amount of graphite to water. Due to manual mixing, the amount of graphite added each time will vary. If too much graphite is added, it will waste graphite and may also clog the nozzle. If too little graphite is added, the mold lubrication effect will be poor, affecting the product filling effect, and the product will easily stick to the mold and cannot be easily removed, reducing the product qualification rate and production efficiency. At the same time, the mold life will be reduced and the production cost will be high. In view of this, an automatic graphite concentration proportioning device and proportioning method are proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: the traditional graphite dilution method is manual dilution, which requires workers to manually add a certain amount of graphite to the water; due to manual dilution, the amount of graphite added each time will be different. If too much graphite is added, it will waste graphite and may also clog the nozzle; if too little graphite is added, the mold lubrication effect will be poor, affecting the product filling effect, and the product will easily stick to the mold and cannot be easily removed, reducing the product qualification rate and production efficiency. At the same time, the mold life will be reduced and the production cost will be high.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic graphite concentration proportioning device, comprising a graphite raw material barrel, a water storage tank and a suction device; The suction device is positioned above the water storage tank, which is located on the side of the graphite raw material barrel. The suction device and the water storage tank are connected via a graphite outlet pipe, and the graphite raw material barrel is connected to the suction device via a graphite inlet pipe. A stirring motor is fixedly installed above the water storage tank. The water storage tank is equipped with blades and a liquid level switch. The liquid level switch has low liquid level and high liquid level functions. The stirring motor is connected to the blades and drives them to rotate.

[0006] As a preferred technical solution for an automatic graphite concentration proportioning device, the water storage tank is provided with a water pipe on one side away from the graphite raw material barrel. The water pipe is equipped with a flow meter, an angle seat valve, a ball valve, a water filter, and a pipe clamp. The ball valve is a manual water replenishment valve, which is used to supplement water in special circumstances.

[0007] As a preferred technical solution for an automatic graphite concentration proportioning device, the water storage tank is equipped with an electrical box on the front, and the electrical box is equipped with an intelligent flow totalizer.

[0008] As a preferred technical solution for an automatic graphite concentration proportioning device, the suction device is provided with a base plate, and a cylinder is provided on one side of the base plate.

[0009] As a preferred technical solution for an automatic graphite concentration proportioning device, the cylinder has a suction piston for telescopic movement at its end, a piston cylinder is provided outside the suction piston, and a cylinder clamp is provided on the outer surface of the piston cylinder to fix the piston cylinder, and the cylinder clamp is placed on the base plate.

[0010] As a preferred technical solution for an automatic graphite concentration proportioning device, the end of the suction piston away from the cylinder is fixedly connected to a liquid vertical tee, and the other two ports of the liquid vertical tee are respectively connected to a check valve outlet and a check valve inlet, both of which are one-way valves.

[0011] As a preferred technical solution for an automatic graphite concentration proportioning device, the check valve outlet and check valve inlet are each connected to a hose connector, and the check valve outlet and check valve inlet are fixed to their respective hose connectors by clamps.

[0012] As a preferred technical solution for an automatic graphite concentration proportioning device, the flexible hose connectors on both sides are respectively connected to the graphite inlet pipe and the graphite outlet pipe.

[0013] As a preferred technical solution for an automatic graphite concentration proportioning device, the base plate is equipped with a pneumatic solenoid valve, wherein the solenoid valve controls the suction piston and the angle seat valve respectively.

[0014] A preferred technical solution for an automatic graphite concentration proportioning method includes the following steps: S1, setting the ratio of graphite to water on an intelligent flow totalizer according to the graphite concentration proportioning process requirements; S2. The liquid level switch detects the liquid level in the water tank. If the liquid level in the water tank is lower than the low liquid level of the liquid level switch, the pneumatic solenoid valve opens and drives the angle seat valve to start, and the water tank starts to fill with water. After the water is filtered by the water filter, the water flows from the water pipe through the flow meter into the water tank. The flow meter calculates and feeds back the water flow to the intelligent flow totalizer. After the required water is injected, the pneumatic solenoid valve drives the angle seat valve to close, and the water stops being injected into the water tank. S3. The pneumatic solenoid valve drives the suction piston to move towards the cylinder, sucking in graphite, so that the graphite enters the liquid vertical tee from the graphite raw material barrel through the graphite inlet pipe and the check valve outlet; then the suction piston moves away from the cylinder, pushing out the graphite, so that the graphite flows from the liquid vertical tee through the check valve inlet and the graphite outlet pipe into the water storage tank. The pneumatic solenoid valve drives the suction piston to stop moving, and the suction piston stops sucking graphite from the graphite raw material barrel. S4. The stirring motor starts, driving the blades to rotate, so that the graphite and water entering the water storage tank are mixed evenly. S5. Repeat steps S2-S4 until the liquid in the tank is higher than the high liquid level of the level switch, then stop the mixing process.

[0015] The beneficial effects of this invention are: (1) The present invention can realize automatic adjustment of graphite concentration, ensure the stability and consistency of graphite concentration, solve the problems of waste and nozzle clogging caused by excessive graphite addition, and reduce production costs; (2) It ensured the lubrication effect of the mold, enabled the product to be demolded smoothly, reduced the unexpected downtime, and solved the product filling effect affected by graphite problems, improved the product qualification rate and production efficiency, while also increasing the mold life and reducing production costs.
