Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a paint mixing tank that facilitates quantitative dispensing. Background Technology

[0002] In the modern paint production field, paint mixing tanks, as core equipment, undertake the crucial task of mixing various paint raw materials. Traditional paint mixing tanks generally consist of a tank body, a stirring device, an inlet, and an outlet. During production, workers need to pour various raw materials such as base materials, pigments, solvents, and additives into the tank in a certain proportion, and then start the stirring device to mix them. However, with the development of the paint industry, the requirements for mixing accuracy, production efficiency, and product quality stability are increasing, and traditional paint mixing tanks have gradually exposed many problems.

[0003] Among these challenges, quantitative measurement is particularly prominent. Currently, most mixing tanks rely on manual estimation of the amount of each raw material added based on experience, or use simple graduated measurement methods, which are prone to significant errors. The proportions of each component in the paint formulation have a significant impact on product performance. For example, an improper pigment ratio can lead to color deviation and insufficient hiding power in the paint; inaccurate solvent content may cause abnormal drying speed and poor leveling properties in the paint. In addition, manual operation is inefficient and cannot meet the needs of rapid and accurate mixing in large-scale production. Moreover, due to the lack of effective quantitative methods, the product quality fluctuates greatly between batches, seriously affecting the market competitiveness of enterprises. In view of this, this paper proposes a paint mixing tank that facilitates quantitative measurement to solve the problems of inaccurate and inefficient quantitative measurement in existing technologies, which has important practical significance for improving the quality and efficiency of paint production. Utility Model Content

[0004] The main objective of this invention is to provide a paint mixing container that facilitates quantitative dispensing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A paint mixing tank for easy quantitative dispensing includes an electrically heated mixing tank body, wherein eight to sixteen independent dispensing devices are installed on the top cover of the electrically heated mixing tank body;

[0007] The independent batching device includes a plunger metering pump and a small paint can. The plunger metering pump is provided with a plunger chamber. The upper part of the plunger chamber is connected to a feed channel. The small paint can is fixedly connected to the upper end of the feed channel. A first inlet check valve is installed in the feed channel. The lower part of the plunger chamber is connected to a discharge channel. An outlet check valve is installed in the discharge channel.

[0008] A movable plunger is slidably installed inside the plunger cavity. A second inlet check valve is fixedly installed on the movable plunger. A first solenoid valve is fixedly connected to one end of the plunger cavity away from the feed channel. Second solenoid valves are fixedly connected to both sides of the feed channel. The air inlets of the first and second solenoid valves on several independent batching devices are fixedly connected to a high-pressure air pump. The air inlet of the high-pressure air pump is fixedly connected to the inner cavity at the top of the electrically heated mixing tank.

[0009] Preferably, an electrical control box is fixedly connected to one side of the electrically heated mixing tank. The electrical control box is electrically connected to the plunger metering pump, the first solenoid valve, the second solenoid valve, and the high-pressure air pump in several independent batching devices through wires.

[0010] Preferably, the air inlet of the high-pressure air pump is fixedly connected to a water gate air filter, and the air inlet of the water gate air filter is connected to the inner cavity at the top of the electric heating stirring tank.

[0011] Preferably, the lower end of the small paint can is tapered, and a sealing cap is fitted onto the upper part of the small paint can, with small air holes provided on the sealing cap.

[0012] Preferably, a flexible hose is fixedly connected to the small vent on the sealing cap. The flexible hose is fixedly connected to the top cover of the electric heating stirring tank, and the lower end of the flexible hose is connected to the inner cavity of the electric heating stirring tank.

[0013] Preferably, a diverter-type connecting pipe is fixedly connected between the air inlet of the first solenoid valve and the second solenoid valve on several independent batching devices and the air outlet of the high-pressure air pump.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The paint mixing tank of this utility model has many outstanding advantages; in terms of precise quantitative measurement, relying on the precise design of the plunger metering pump and the precise displacement of the movable plunger, it can accurately extract and transport the paint in the small paint tank, ensuring the accuracy of mixing from the source, greatly reducing the paint quality problems caused by mixing errors, improving product quality stability, and meeting the strict requirements of paint quality in different production scenarios.

[0016] 2. In terms of efficiency improvement, multiple independent batching devices can work simultaneously and complete the batching action in parallel according to a preset program, which greatly shortens the batching time, effectively improves production efficiency, meets the needs of large-scale industrial production, and helps enterprises increase production capacity.

[0017] 3. In terms of maintenance and continuous accurate batching, after each batching is completed, the high-pressure air pump, under the control of the electrical control box, works in conjunction with the first and second solenoid valves to use high-pressure gas to thoroughly clean the plunger cavity, the area below the feed channel, and the discharge channel. This promptly removes residual paint, prevents the paint from drying and affecting the accuracy of subsequent batching, extends the service life of the equipment, and ensures that the equipment is always in good operating condition.

[0018] 4. The air pressure balance design is also crucial. The small paint can is connected to the electrically heated mixing tank through a hose, which not only prevents air from entering the tank and causing the paint to solidify, but also ensures that the paint flows smoothly during the mixing process, further improving the mixing efficiency and accuracy.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-3 As shown, a paint mixing tank that facilitates quantitative dispensing includes an electrically heated mixing tank body 1, and eight to sixteen independent dispensing devices 2 are installed on the top cover of the electrically heated mixing tank body 1.

[0025] In this embodiment, the independent batching device 2 includes a plunger metering pump 201 and a small paint can 202. The plunger metering pump 201 is provided with a plunger cavity 203. The upper part of the plunger cavity 203 is connected to a feed channel 204. The small paint can 202 is fixedly connected to the upper end of the feed channel 204. A first inlet check valve 206 is installed in the feed channel 204. The lower part of the plunger cavity 203 is connected to a discharge channel 205. An outlet check valve 207 is installed in the discharge channel 205.

[0026] In this embodiment, the lower end of the small paint can 202 is conical, and a sealing cap 211 is fitted and installed on the upper part of the can body of the small paint can 202. The sealing cap 211 is provided with small air holes. The conical design facilitates the smooth flow of paint into the feed channel 204. The sealing cap 211 can prevent paint from evaporating and external impurities from entering. The small air holes play a role in balancing air pressure and ensuring that the paint can be discharged smoothly.

[0027] In this embodiment, a flexible hose 208 is fixedly connected to the small air hole on the sealing cap 211. The flexible hose 208 is fixedly connected to the top cover of the electric heating mixing tank 1, and the lower end of the flexible hose 208 is connected to the inner cavity of the electric heating mixing tank 1. The flexible hose 208 connects the small paint can 202 with the inside of the electric heating mixing tank 1, balances the air pressure between the two, and further ensures the smoothness of paint discharge.

[0028] In this embodiment, a movable plunger is slidably installed in the plunger cavity 203, and a second inlet check valve is fixedly installed on the movable plunger. A first solenoid valve 209 is fixedly connected to one end of the plunger cavity 203 away from the feed channel 204. A second solenoid valve 210 is fixedly connected to both sides of the feed channel 204. The air inlets of the first solenoid valve 209 and the second solenoid valve 210 on several independent batching devices 2 are fixedly connected to a high-pressure air pump 4. The air inlet of the high-pressure air pump 4 is fixedly connected to the inner cavity at the top of the electric heating mixing tank 1. The air inlet of the high-pressure air pump 4 is fixedly connected to a water gate air filter 6. The air inlet of the water gate air filter 6 is interconnected with the inner cavity at the top of the electric heating mixing tank 1. The water gate air filter 6 can effectively filter impurities in the air.

[0029] In this embodiment, a diversion pipe 3 is fixedly connected between the air inlets of the first solenoid valve 209 and the second solenoid valve 210 on several independent batching devices 2 and the air outlet of the high-pressure air pump 4. The diversion pipe 3 can evenly distribute the gas output by the high-pressure air pump 4 to several first solenoid valves 209 and several second solenoid valves 210, ensuring the consistency and stability of the operation of each independent batching device 2.

[0030] In this embodiment, an electrical control box 5 is fixedly connected to one side of the electrically heated mixing tank 1. The electrical control box 5 is electrically connected to the plunger metering pump 201, the first solenoid valve 209, the second solenoid valve 210 and the high-pressure air pump 4 in several independent batching devices 2 through wires. The electrical control box 5 can centrally control each component to realize automated batching operation and improve batching efficiency and accuracy.

[0031] In this embodiment, when mixing paint, the paint mixing tank that facilitates quantitative mixing first loads various paint raw materials into the corresponding small paint tanks 202, and ensures that the sealing cap 211 is installed in place. The small air hole on the sealing cap 211 is connected to the inner cavity of the electric heating stirring tank 1 through the hose 208, so as to balance the air pressure between the small paint tank 202 and the electric heating stirring tank 1, creating conditions for smooth mixing in the future.

[0032] When the batching operation starts, the worker inputs the preset batching program into the electrical control box 5. After receiving the instruction, the electrical control box 5 sends a working signal to the plunger metering pump 201. At this time, the movable plunger of the plunger metering pump 201 begins to move horizontally backward, and a negative pressure is formed in the plunger cavity 203. Since the first inlet check valve 206 is installed in the feed channel 204, the first inlet check valve 206 opens under the action of negative pressure. The paint in the small paint can 202 flows into the plunger cavity 203 along the feed channel 204 under the combined action of air pressure and gravity.

[0033] When the movable plunger moves backward to the set position, the amount of paint sucked into the plunger cavity 203 reaches the predetermined amount of material. Then, the electrical control box 5 controls the movable plunger of the plunger metering pump 201 to move forward horizontally. During the forward pushing of the movable plunger, the outlet check valve 207 in the discharge channel 205 opens, while the first inlet check valve 206 closes, thereby preventing the paint from flowing back. The movable plunger smoothly pushes the measured amount of paint in the plunger cavity 203 from the discharge channel 205 into the electrically heated mixing tank 1.

[0034] After each batching operation is completed, in order to ensure the cleanliness of the equipment and avoid residual paint affecting the accuracy of subsequent batching, the electrical control box 5 will control the high-pressure air pump 4 to start. The air inlet of the high-pressure air pump 4 is connected to the inner cavity at the top of the electric heating mixing tank 1 through the water gate air filter 6, which can filter impurities in the air. The high-pressure gas output by the high-pressure air pump 4 is delivered to the first solenoid valve 209 and the second solenoid valve 210 of each independent batching device 2 through the diversion connecting pipe 3.

[0035] After the first solenoid valve 209 is opened, high-pressure gas enters the plunger chamber 203, pushing the second inlet check valve inside the movable plunger to push out the residual paint in the plunger chamber 203. At the same time, the second solenoid valve 210 is opened, and high-pressure gas enters below the feed channel 204 to clean the residual paint in that area. All the residual paint and the paint pushed by the high-pressure gas are eventually discharged through the discharge channel 205, thereby achieving comprehensive cleaning of the plunger chamber 203, the area below the feed channel 204, and the discharge channel 205 in the plunger metering pump 201.
