Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, and in particular to a color mixing and proportioning device for pigment production. Background Technology

[0002] Iron oxide pigments mainly refer to four categories of coloring pigments based on iron oxides: iron oxide red, iron oxide yellow, iron oxide black, and iron oxide brown. Among them, iron oxide red is the main variety of iron oxide pigments, accounting for approximately 50% of all iron oxide pigments. In addition, mica iron oxide used as an anti-rust pigment and magnetic iron oxide used as a magnetic recording material also fall under the category of iron oxide pigments. Iron oxide pigments have a wide range of colors, a broad color spectrum, high hiding power, and strong tinting strength. The main colors are red, yellow, and black. Through blending, composite pigments with a series of color spectrums such as orange, brown, and green can also be obtained. Iron oxide pigments have excellent lightfastness, weather resistance, acid resistance, alkali resistance, and solvent resistance, and are also non-toxic. They are widely used in building materials, coatings, plastics, electronics, tobacco, pharmaceuticals, rubber, ceramics, inks, magnetic materials, papermaking, colored bricks, artificial marble, terrazzo coloring, and other fields. The color mixing and proportioning device for pigment production is a key piece of equipment specifically used for color mixing and proportioning in the iron oxide pigment production process. This device plays a vital role in the production of iron oxide pigments. It can not only ensure the color accuracy and consistency of the pigments, but also improve production efficiency.

[0003] To this end, Chinese patent application CN208727327U discloses a pigment production mixing device, including a support base, a mixing tank fixedly mounted on the top of the support base, a rotating hole on the inner wall of the top of the mixing chamber, a support rod rotatably mounted in the rotating hole, the bottom end of the support rod extending into the mixing chamber and fixedly mounted with a spiral plate, the top of the spiral plate having multiple through holes, a protective shell on the top of the support base, a first bevel gear located inside the protective shell, a motor fixedly mounted on the top of the motor base, a second bevel gear fixedly sleeved on the output shaft of the motor, the second bevel gear meshing with the first bevel gear, a feed hopper fixedly mounted on the top of the mixing tank, the bottom of the feed hopper extending into the mixing chamber, and four rectangularly distributed support frames fixedly mounted on the bottom of the support base. This utility model is easy to operate and has high mixing efficiency, thereby improving the efficiency of pigment production.

[0004] While current color mixing devices can generally meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of color mixing devices being unable to inject pigments quantitatively. In order to ensure the accuracy of pigment color matching, it is necessary to control the proportion and amount of various pigments. At the same time, it is also necessary to inject pigments quantitatively in subsequent production to ensure that the color mixed each time is consistent with the preset formula, thereby achieving the requirement of color accuracy. It is difficult to accurately control the injection amount by manually injecting pigments.

[0006] 2. The problem of difficulty in cleaning the color mixing device: During use, pigments may adhere to the inner wall of the device, the stirring blades or other parts. If cleaning is not timely or thorough, these residual pigments will affect the accuracy of the next color mixing. Utility Model Content

[0007] The purpose of this invention is to provide a color mixing and proportioning device for pigment production, which solves the shortcomings of existing color mixing and proportioning devices that are difficult to quantitatively inject pigments and are difficult to clean conveniently.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a color mixing and proportioning device for pigment production, including a support frame;

[0009] A mixing tank is welded to the top of the support, a cover is installed on the top of the mixing tank, and a feeding mechanism is fixed to the top of the cover. The feeding mechanism includes a feeding port, a control tube, a feeding pipe, a first motor, and a first rotating shaft. The feeding pipe passes through the inside of the cover. A control tube is integrally formed at the top of the feeding pipe, and a feeding port is integrally formed at the top of the control tube.

[0010] A first motor is installed at one end of the control tube, and a first rotating shaft is installed at the output end of the first motor. A second motor is fixed at the top of the cover, and a second rotating shaft is installed at the output end of the second motor. A stirring blade is installed on the outside of the second rotating shaft.

[0011] A support frame is welded to the bottom of the mixing tank, a filter screen is welded to the top of the support frame, a solenoid valve is installed at the bottom of the support frame, a cleaning mechanism is installed inside the mixing tank, a wear-resistant structure is provided on the inner wall of the cleaning mechanism, and a discharge port is welded to the bottom of the mixing tank.

[0012] In use, different pigments are first injected through different inlets. The first motor is started to drive the control blade to rotate, which in turn drives the pigments into the mixing tank through the inlet pipe. The injection amount of different pigments is controlled by controlling the rotation time of the control blade. After multiple pigments fall into the mixing tank, the second motor drives the stirring blade to rotate so that the multiple pigments are mixed evenly. After the evenly mixed pigments form a new color, the solenoid valve is opened to allow the pigments to be discharged from the outlet. The filter screen ensures that the pigments do not clump. After the pigments are discharged, the water pump is started to spray cleaning liquid into the mixing tank to clean the inside and finally discharge it from the outlet.

[0013] Furthermore, a control blade is installed on the outer side of the first rotating shaft. The control blade is arranged in a ring. The injected pigment can be blocked in the control tube by the control blade and fall as the control blade rotates.

[0014] Furthermore, a slider is provided at the bottom end of the second rotating shaft, and a groove is provided inside the support frame. The second rotating shaft and the support frame are slidably connected, making the rotation of the second rotating shaft and the stirring blade more stable.

[0015] Furthermore, the interior of the stirring blade is uniformly provided with through holes, which are evenly distributed inside the stirring blade. During stirring, the pigment can pass through the through holes, making the flow of the stirring process more complex and the stirring more uniform.

[0016] Furthermore, the cleaning mechanism includes a water guide pipe, a nozzle, a water suction pipe, a water pump, a water storage tank, a water inlet, and a scraper. The water guide pipe is installed inside the mixing tank, and a nozzle is provided on the inner side of the water guide pipe. A water suction pipe is integrally formed on one side of the water guide pipe, and a water pump is installed on the outer side of the water suction pipe. A water storage tank is fixed to the bottom of the water pump, and a water inlet is opened on one side of the top of the water storage tank to avoid residual pigment from affecting the next color mixing.

[0017] Furthermore, the scrapers are fixed on both sides of the second rotating shaft, and the scrapers are symmetrically distributed about the central axis of the second rotating shaft. The scrapers can better remove the pigments remaining on the inner wall of the mixing tank and the filter screen.

[0018] Furthermore, the wear-resistant structure includes a phenolic epoxy resin coating, a polyurethane coating, and a glass flake coating. The glass flake coating is disposed on the inner wall of the mixing tank, and a polyurethane coating is disposed on the inner side of the glass flake coating. A phenolic epoxy resin coating is disposed on the inner side of the polyurethane coating, thereby preventing the chemical substances in the pigment from corroding the inner wall.

[0019] This utility model provides a color mixing and proportioning device for pigment production. Its advantages are as follows: by opening multiple feed ports at the top of the cover, each feed port can inject different colored pigments. The injected pigments are blocked in the control tube by the control blade. By controlling the start-up time of the first motor, the first motor drives the control blade to rotate through the first rotating shaft, allowing a certain amount of pigment to enter the mixing tank through the feed pipe. Multiple first motors can be controlled independently, thereby adjusting various proportions to form new colors by changing the injection amount of different colors. The operation is simple and the control is precise. The same proportion can be repeated, ensuring the stability of production quality. This achieves the purpose of the color mixing and proportioning device to inject pigments quantitatively.

[0020] By installing a ring-shaped water guide pipe inside the mixing tank, after the pigment is discharged from the mixing tank, the water pump is started to inject the cleaning agent or clean water in the water storage tank into the water guide pipe through the water pump pipe. The cleaning agent is then evenly sprayed into the mixing tank through the nozzles. The second motor is started to rotate the mixing blades and scraper, which can drive the internal cleaning agent to clean the inside of the mixing tank. At the same time, the scraper can better scrape off the pigment residue on the inner side wall and filter screen of the mixing tank, so as to avoid the pigment residue affecting the next color mixing. Finally, the wastewater after cleaning can be discharged through the discharge port, thus achieving the purpose of convenient cleaning of the color mixing device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 One embodiment of this utility model is a color mixing and proportioning device for pigment production, which includes a support 1.

[0029] A mixing tank 2 is welded to the top of the support 1, and a cover 3 is installed on the top of the mixing tank 2.

[0030] The top of the cover 3 is fixed with a feeding mechanism 4. The feeding mechanism 4 includes a feeding port 401, a control tube 402, a feeding tube 403, a first motor 404, and a first rotating shaft 405. The feeding tube 403 passes through the interior of the cover 3. The top of the feeding tube 403 is integrally formed with a control tube 402. The top of the control tube 402 is integrally formed with a feeding port 401. The first motor 404 is installed at one end inside the control tube 402. The first rotating shaft 405 is installed at the output end of the first motor 404. Control blades 406 are installed on the outside of the first rotating shaft 405. The control blades 406 are arranged in a ring.

[0031] See attached document Figure 1-4As shown, multiple feed ports 401 are opened at the top of the cover 3. Each feed port 401 can be injected with pigment of different colors. The injected pigment is blocked in the control tube 402 by the control blade 406. By controlling the start time of the first motor 404, the first motor 404 drives the control blade 406 to rotate through the first rotating shaft 405, and allows a certain amount of pigment to enter the mixing tank 2 through the feed tube 403. Multiple first motors 404 can be controlled independently, so by changing the injection amount of different colors, various ratios can be adjusted to form new colors. The operation is simple and the control is precise. The same ratio can be repeated, ensuring the stability of production quality.

[0032] A second motor 5 is fixed to the top of the cover 3. A second rotating shaft 6 is installed at the output end of the second motor 5. A stirring blade 7 is installed on the outside of the second rotating shaft 6. Through holes 8 are evenly distributed inside the stirring blade 7.

[0033] A support frame 9 is welded to the bottom of the mixing tank 2. A slider is provided at the bottom of the second rotating shaft 6. A sliding groove is provided inside the support frame 9. The second rotating shaft 6 and the support frame 9 are slidably connected. A filter screen 10 is welded to the top of the support frame 9. A solenoid valve 11 is installed at the bottom of the support frame 9.

[0034] The mixing tank 2 is equipped with a cleaning mechanism 12, which includes a water guide pipe 1201, a nozzle 1202, a water suction pipe 1203, a water pump 1204, a water storage tank 1205, a water inlet 1206, and a scraper 1207. The water guide pipe 1201 is installed inside the mixing tank 2. The nozzle 1202 is provided on the inner side of the water guide pipe 1201. The water suction pipe 1203 is integrally formed on one side of the water guide pipe 1201. The water pump 1204 is installed on the outer side of the water suction pipe 1203. The water storage tank 1205 is fixed at the bottom of the water pump 1204. The water inlet 1206 is opened on one side of the top of the water storage tank 1205. The scraper 1207 is fixed on both sides of the second rotating shaft 6. The scraper 1207 is symmetrically distributed about the central axis of the second rotating shaft 6.

[0035] See attached document Figure 1-5 As shown, an annular water guide pipe 1201 is installed inside the mixing tank 2. After the pigment is discharged from the mixing tank 2, the water pump 1204 is started to inject the cleaning agent or clean water in the water storage tank 1205 into the water guide pipe 1201 through the water pump pipe 1203. The cleaning agent is then evenly sprayed into the mixing tank 2 through the nozzle 1202. The second motor 5 is started to make the mixing blade 7 and the scraper 1207 rotate, which can drive the internal cleaning agent to clean the inside of the mixing tank 2. At the same time, the scraper 1207 can better scrape off the pigment residue on the inner wall of the mixing tank 2 and the filter screen 10, so as to avoid the pigment residue affecting the next color mixing. Finally, the wastewater after cleaning can be discharged through the discharge port 14.

[0036] The inner wall of the cleaning mechanism 12 is provided with a wear-resistant structure 13, which includes a phenolic epoxy resin coating 1301, a polyurethane coating 1302, and a glass flake coating 1303. The glass flake coating 1303 is provided on the inner wall of the mixing tank 2. The inner side of the glass flake coating 1303 is provided with a polyurethane coating 1302, and the inner side of the polyurethane coating 1302 is provided with a phenolic epoxy resin coating 1301. A discharge port 14 is welded to the bottom of the mixing tank 2.

[0037] See attached document Figure 3-5 As shown, the inner wall of the mixing tank 2 will rub against the pigment, and the chemical substances in the pigment will corrode the inner wall. The glass flake coating 1303, which is in close contact with the inner wall of the mixing tank 2, has a unique flake structure that can effectively prevent the penetration of corrosive media. The polyurethane coating 1302 in the middle has excellent chemical corrosion resistance and adhesion. The phenolic epoxy resin coating 1301, which is in direct contact with the pigment, has excellent corrosion resistance and wear resistance, and can resist the erosion of various chemical substances. At the same time, it has good mechanical properties, which can ensure the integrity of the mixing tank 2 and extend the overall service life.
