Description

Technical Field

[0001] This utility model relates to the field of coating processing equipment, and in particular to a circulating cylinder for diluting environmentally friendly coatings. Background Technology

[0002] In the production and use of environmentally friendly coatings, high-concentration coatings often need to be diluted to meet different construction needs or achieve specific performance standards. The main function of the thinner used is to reduce the viscosity of the coating and improve its performance. Traditional dilution equipment generally uses a stirring shaft for agitation or a pump for circulation dilution. The first method has limitations: the stirring effect of the shaft is limited; secondly, during agitation, the original coating clumps together and accumulates at the bottom of the tank, which the shaft cannot completely agitate, resulting in uneven mixing, low efficiency, and waste generation. This not only affects the final quality of the coating but also increases production costs and environmental burden. The second method, however, involves high initial power consumption from the pump, which can easily overheat, and incomplete dilution. Utility Model Content

[0003] The main purpose of this invention is to solve the problems of uneven coating dilution and coating agglomeration at the bottom of the cylinder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmentally friendly coating dilution circulating cylinder mainly includes a cylinder body, a support frame, a feed inlet, a stirring mechanism, a circulating mechanism, a storage tank, and a feed pipe. The cylinder body is fixedly mounted on the support frame, and the storage tank is installed at the bottom of the support frame. The storage tank is connected to the feed inlet through the feed pipe. The feed inlet is located at the top of the cylinder body. A tripod is also installed in the middle of the support frame, positioned above the storage tank. The circulating mechanism is installed at the bottom of the cylinder body. The stirring mechanism includes a stirring motor, a rotating shaft, a fixed seat, stirring blades, a fixed sleeve, connecting rods, a spiral rod, and a scraper. The output end of the stirring motor is connected to the rotating shaft through a coupling. Several fixed seats are installed on the rotating shaft, and stirring blades are symmetrically installed on each fixed seat. A fixed sleeve is installed at the bottom of the rotating shaft, and connecting rods are symmetrically arranged on both sides of the fixed sleeve. Each connecting rod is parallel to the bottom of the cylinder body, and a spiral rod and a scraper are also provided on each connecting rod.

[0006] Preferably, a breather valve is also provided on the top of the cylinder.

[0007] Preferably, the helical rod is located at the top of each connecting rod, and there are no fewer than eight helical rods.

[0008] Preferably, the bottom of the connecting rod is connected to the scraper via a connecting arm, the two scrapers are staggered, and the bottom of the scraper is in contact with the bottom of the cylinder.

[0009] Preferably, a liquid level tube is also installed on one side of the cylinder for observing the height and concentration of the diluent.

[0010] Preferably, the circulation mechanism includes a discharge pipe, a three-way valve, a first pipe, a circulation pump, a second pipe, and a connecting pipe. The discharge pipe is installed at the bottom of the cylinder body, and a three-way valve is installed on the discharge pipe. One end of the three-way valve is connected to the first pipe, the other end of the first pipe is connected to the input end of the circulation pump, the output end of the circulation pump is connected to the second pipe, the circulation pump is mounted on a tripod, and the other end of the second pipe is connected to the connecting pipe, which is installed on one side of the cylinder body.

[0011] Preferably, the portion of the connecting pipe extending into the cylinder body is vertically positioned.

[0012] Preferably, a flange is provided at the bottom of the support frame for fixing the support frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] The stirring mechanism acts as a primary dilution unit, thoroughly mixing the diluent and coating to ensure complete contact and mixing within the cylinder, accelerating the dissolution and dilution of the diluent. The screw rod mainly stirs the agglomerated mixture accumulated at the bottom of the cylinder, while the staggered scrapers constantly clean the substances adhering to the inner wall, preventing agglomeration and reducing the likelihood of clogging the discharge pipe. Subsequently, a secondary dilution occurs under the action of the circulation mechanism, powered by a circulation pump. When the mixture reaches the predetermined uniformity and concentration, the three-way valve is controlled to discharge the mixture from the outlet. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-4 An environmentally friendly coating dilution circulating tank mainly includes a tank body 1, a support frame 2, a feed inlet 3, a stirring mechanism 4, a circulating mechanism 5, a storage tank 6, and a feed pipe 7. The tank body 1 is fixedly mounted on the support frame 2. The storage tank 6 is installed at the bottom of the support frame 2. The feed inlet 3 is provided at the top of the tank body 1. The storage tank 6 is connected to the feed inlet 3 through the feed pipe 7. A tripod 8 is also provided in the middle of the support frame 2, and the tripod 8 is located above the storage tank 6. The circulating mechanism 5 is installed at the bottom of the tank body 1. The stirring mechanism 4 includes a stirring motor. 40. A rotating shaft 41, a fixed seat 42, a stirring blade 43, a fixed sleeve 44, a connecting rod 45, a spiral rod 46, and a scraper 47. The output end of the stirring motor 40 is connected to the rotating shaft 41 via a coupling. Several fixed seats 42 are installed on the rotating shaft 41. A stirring blade 43 is symmetrically installed on each fixed seat 42. A fixed sleeve 44 is installed at the bottom of the rotating shaft 41. Connecting rods 45 are symmetrically arranged on both sides of the fixed sleeve 44. Each connecting rod 45 is parallel to the bottom of the cylinder 1. A spiral rod 46 and a scraper 47 are also provided on each connecting rod 45.

[0022] Stirring process:

[0023] First, the paint and thinner are supplied to the interior of the cylinder 1 via the feed pipe 7 through the supply pump in the storage tank 6. Then, the stirring mechanism 4 is activated for stirring. After stirring for a certain period of time, the three-way valve 51 is controlled to circulate and dilute the paint. The stirring mechanism 4 replaces the traditional stirring shaft, and the stirring blades 43 make the internal stirring range larger, the force stronger, and the mixing more uniform. To avoid agglomeration at the bottom, a connecting rod 45, a spiral rod 46, and a scraper 47 are designed at the bottom of the rotating shaft 41. During the stirring process, the spiral rod 46 breaks up the thicker paint at the bottom, and the gaps between the spiral rods 46 allow for flow, resulting in good dispersion and preventing the paint from becoming increasingly thick. Secondly, the scraper 47 scrapes off the sticky paint at the bottom during rotation, facilitating dilution.

[0024] The top of the cylinder 1 is also provided with a breather valve 9, which mainly serves to allow air to circulate and release pressure.

[0025] The helical rod 46 is located on the upper part of each connecting rod 45, and the number of the helical rods 46 is not less than eight.

[0026] The bottom of the connecting rod 45 is connected to the scraper 47 via a connecting arm. The two scrapers 47 are staggered, which improves the stability of the rotating shaft 41. The bottom of the scraper 47 is in contact with the bottom of the cylinder 1.

[0027] A liquid level tube 10 is also installed on one side of the cylinder 1 for observing the height and concentration of the diluent.

[0028] The circulation mechanism 5 includes a discharge pipe 50, a three-way valve 51, a first pipe 52, a circulation pump 53, a second pipe 54, and a connecting pipe 55. The discharge pipe 50 is installed at the bottom of the cylinder body 1, and the three-way valve 51 is installed on the discharge pipe 50. One end of the three-way valve 51 is connected to the first pipe 52, and the other end of the first pipe 52 is connected to the input end of the circulation pump 53. The output end of the circulation pump 53 is connected to the second pipe 54. The circulation pump 53 is installed on a tripod 8, and the other end of the second pipe 54 is connected to the connecting pipe 55. The connecting pipe 55 is installed on one side of the cylinder body 1.

[0029] Cyclic dilution:

[0030] After mixing for a period of time, start the circulation pump 53 and open the three-way valve 51, allowing the internal mixture to re-enter the cylinder 1 through the first pipe 52 and the second pipe 54, where it is diluted during the mixing process. Repeat this process several times until the diluted paint reaches the required consistency.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that the part of the connecting pipe 55 that extends into the cylinder 1 is set vertically. The vertical setting will not damage the stirring blade 43. If it is set horizontally, the paint will directly hit the stirring blade 43, which will damage the stirring blade 43 over time, causing deflection and poor stability. The bottom of the support frame 2 is provided with a flange 11 for fixing the support frame.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
