[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A filtering feeding device for producing hydroxyethylethylenediaminetrimethylenephosphonic acid comprises a box body 1 and a liquid inlet pipe 2, wherein the liquid inlet pipe 2 is connected and arranged at the top of the box body 1, a dilution mechanism 3 for breaking up agglomerates of materials is arranged inside the box body 1, and a switch assembly 4 for replacing and repairing the dilution mechanism 3 is arranged outside the box body 1;

[0031] The dilution mechanism 3 includes a conical portion 301, a motor 302, a stirring rod 303, a filter cartridge 304, a connecting plate 305 and a feeding pipe 306. The conical portion 301 is welded to the inside of the casing 1, the motor 302 is bolted to the top of the casing 1, the stirring rod 303 is arranged inside the casing 1, the filter cartridge 304 is threadedly connected to the bottom of the conical portion 301, the connecting plate 305 is bolted to the bottom of the filter cartridge 304, the feeding pipe 306 is rotatably connected to the bottom of the connecting plate 305, and the top of the stirring rod 303 is fixedly connected to the output end of the motor 302.

[0032] Specifically, Figure 4 As shown, a storage cavity 5 is provided inside the conical portion 301 , and a resistance wire 6 is arranged inside the storage cavity 5 .

[0033] Specifically, Figure 1 As shown, the top of the box body 1 is connected to an exhaust pipe 7, the top of the exhaust pipe 7 is connected to a frame body 8, and an exhaust groove 9 is opened on the outer wall of the frame body 8.

[0034] Specifically, Figure 4 As shown, a handle 10 for facilitating the rotation of the filter cartridge 304 is bolted onto the outer wall of the filter cartridge 304 , and the handles 10 are three in number and distributed around the circumference.

[0035] Specifically, Figure 4 As shown, a slide groove 11 is opened on the outer wall of the feeding pipe 306 , and a limiting rod 12 is bolted on the inner wall of the box body 1 , and one end of the limiting rod 12 extends to the inside of the slide groove 11 and is slidably connected to the slide groove 11 .

[0036] Specifically, Figure 4 As shown, a scraper 13 is bolted to the outer wall of the stirring rod 303 , and the side wall of the scraper 13 is tightly fitted with the top of the tapered portion 301 .

[0037] When in use, the motor 302 and the resistance wire 6 are connected to an external power source in advance, and then the motor 302 is started. The motor 302 drives the stirring rod 303 to rotate, and then the resistance wire 6 heats the space between the tapered portion 301 and the housing 1. Then, the hydroxyethylethylenediaminetrimethylenephosphonic acid solution enters the interior of the housing 1 through the liquid inlet pipe 2. The hydroxyethylethylenediaminetrimethylenephosphonic acid particles will agglomerate in the suspension, that is, the particles will aggregate with each other to form larger agglomerates. This agglomeration will increase the viscosity of the suspension. At this time, the motor 302 drives the stirring rod 303 to rotate, thereby breaking the agglomeration structure of these particles and making them more evenly dispersed in the liquid, thereby reducing the overall viscosity. Then the resistance wire 6 will heat the hydroxyethylethylenediaminetrimethylenephosphonic acid solution on the tapered portion 301, and the agglomeration will increase. Heat allows the molecules inside hydroxyethylethylenediaminetrimethylenephosphonic acid to obtain more energy, and its thermal motion increases, which increases the kinetic energy between molecules, making it easier for the molecules to overcome the attractive and repulsive forces between each other, thereby reducing the interaction forces between molecules. This makes it easier for the molecules of hydroxyethylethylenediaminetrimethylenephosphonic acid to pass through the space between each other when flowing, thereby reducing its overall viscosity. The liquid then passes through the filter cartridge 304 and is then discharged through the feed pipe 306, thereby achieving the effects of filtering and feeding. When the filter cartridge 304 needs to be replaced, wait for the filter cartridge 304 to cool down, then rotate the filter cartridge 304 down using the handle 10, and then because the filter cartridge 304 is bolted to the connecting plate 305, the bolts on the filter cartridge 304 can be unscrewed for replacement or cleaning.

[0038] Specifically, Figure 5 As shown, the switch assembly 4 includes a switch slot 401, an arc slot 402 and a switch door 403. The switch slot 401 is opened on the outer wall of the box body 1, the arc slot 402 is opened on the side wall of the switch slot 401, and the switch door 403 is slidably connected to the inside of the switch slot 401.

[0039] Specifically, Figure 1 As shown, an extension plate 14 is bolted to the outer wall of the switch door 403 to facilitate the movement of the switch door 403.

[0040] When replacing the filter cartridge 304 , the switch door 403 is slid inside the switch slot 401 and the arc slot 402 through the extension plate 14 , so that the switch slot 401 is opened and the filter cartridge 304 is exposed to the field of vision, making it convenient to replace the filter cartridge 304 .

[0041] By adopting the above technical solution, the problem that the existing hydroxyethylethylenediaminetrimethylenephosphonic acid production filtering feeding device can only clean the inside of the filter element regularly during use, and when the filter element is damaged, it cannot be quickly disassembled, thereby affecting the filtering efficiency is solved.

[0042] Working principle: When in use, the motor 302 and the resistance wire 6 are connected to the external power supply in advance, and then the motor 302 is started, and the motor 302 drives the stirring rod 303 to rotate, and then the resistance wire 6 heats the space between the tapered portion 301 and the box body 1, and then the hydroxyethylethylenediaminetrimethylenephosphonic acid solution enters the interior of the box body 1 through the liquid inlet pipe 2. The hydroxyethylethylenediaminetrimethylenephosphonic acid particles will agglomerate in the suspension, that is, the particles will aggregate with each other to form larger agglomerates, and this agglomeration will increase the viscosity of the suspension. At this time, the motor 302 drives the stirring rod 303 to rotate, thereby breaking the agglomeration structure of these particles and making them more evenly dispersed in the liquid, thereby reducing the overall viscosity, and then the resistance wire 6 will heat the hydroxyethylethylenediaminetrimethylenephosphonic acid solution on the tapered portion 301, and the heating allows the molecules inside the hydroxyethylethylenediaminetrimethylenephosphonic acid to obtain more energy. Its thermal motion increases, which increases the kinetic energy between molecules, making it easier for molecules to overcome mutual attraction and repulsion, thereby reducing the interaction force between molecules. This makes it easier for the molecules of hydroxyethylethylenediaminetrimethylenephosphonic acid to pass through the space between each other when flowing, thereby reducing its overall viscosity. The liquid then passes through the filter cartridge 304 and is then discharged through the feed pipe 306, thereby achieving the effects of filtering and feeding. When the filter cartridge 304 needs to be replaced, wait for the filter cartridge 304 to cool down, then use the extension plate 14 to slide the switch door 403 inside the switch slot 401 and the arc slot 402, so that the switch slot 401 is opened, exposing the filter cartridge 304 to the field of vision, and then rotate the filter cartridge 304 down through the handle 10. Then, because the filter cartridge 304 is bolted to the connecting plate 305, the bolts on the filter cartridge 304 can be unscrewed for replacement or cleaning.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
