[0026] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0027] In this embodiment, Figures 1 to 5 As shown, a quantitative feeding device for iminodiacetic acid includes a silo 2, a feeding hopper 7 is fixed at the feed inlet above the silo 2, a discharging hopper 13 is fixed at the discharging outlet below the silo 2, and the feeding hopper 7 and the discharging hopper 13 are arranged relative to each other; a driving mechanism is arranged on the silo 2, a main shaft 5 is fixed to the output end of the driving mechanism and extends into the silo 2, a distribution impeller 4 and a scraping impeller 3 are fixed on the main shaft 5, the distribution impeller 4 sweeps the material accumulated on the high side to the other side, and the scraping impeller 3 is used to sweep the material at the bottom of the silo 2 toward the outer periphery.

[0028] In one or more embodiments of the present invention, the bottom of the silo 2 protrudes upward to form a conical surface, and the scraping impeller 3 is used to scrape the material on the conical surface.

[0029] In this embodiment, due to the position of the feeding hopper 7 and the characteristics of the material, after the material enters the silo 2, the material tends to the side of the feeding hopper 7, and the material on the discharge side is less. Then, the material on the higher side is pushed to the lower side by the distribution impeller 4. After 3 to 5 turns, the material surface in the silo gradually becomes smooth.

[0030] In one or more embodiments of the present invention, the distribution impeller 4 includes a first sleeve fixed on the main shaft, and four distribution blades 41 in a circular array are fixed to the outer side of the first sleeve. The distribution blades 41 are generally arc-shaped structures.

[0031] In this embodiment, the driving direction of the distribution blade 41 is opposite to the direction of the arc-shaped protrusion. The arrangement of the distribution blade 41 with an arc-shaped structure enables the material to be better captured and pushed, thereby improving the uniformity of the pushing.

[0032] In one or more embodiments of the utility model, the scraper impeller 3 includes a second sleeve fixed on the main shaft, and two centrally symmetrical scraper blades 31 and two centrally symmetrical pusher blades 32 are fixed to the outer side of the second sleeve, and the scraper blades 31 and the pusher blades 32 are also arc-shaped structures; the length of the scraper blade 31 is greater than the length of the pusher blade 32, and the height of the pusher blade 32 is greater than the height of the scraper blade 31.

[0033] In this embodiment, due to the poor fluidity of the material, the short and high pusher blade 32 on the scraper impeller 3 is required to push the material from the center to the periphery, and then the long and narrow scraper blade 31 pushes the material to the discharge port. The distribution blade 41, scraper blade 31 and pusher blade 32 are all fixed by bolts for easy disassembly and replacement. The unit feed amount of the device can be adjusted by adjusting the height of the scraper blade and the gap between the discharge adjustment block and the scraper blade.

[0034] In one or more embodiments of the utility model, the driving mechanism includes a bracket 6 fixed at the upper center position of the silo 2, a mixing frame 8 is fixed on the bracket, a reduction motor 9 is fixed on the mixing frame 8, and the main shaft 5 is axially connected to the output end of the reduction motor 9.

[0035] In one or more embodiments of the utility model, a discharging adjustment block 11 is provided in the silo 2, and the discharging adjustment block 11 is located on the discharging port. A liftable discharging adjustment rod 10 is provided at the inner edge of the silo 2, and the lower side of the discharging adjustment rod 10 is fixed to the discharging adjustment block 11.

[0036] In this embodiment, the discharge adjustment rod 10 is fixed by bolts or pins, and can also be raised and lowered by threads. The discharge adjustment block 11 can adjust the opening up and down, firstly to adjust the instantaneous feed amount, and secondly to prevent the material around the discharge port from flowing to the discharge port and causing blockage when the material warehouse is full. The feed amount can also be adjusted by adjusting the output speed of the reduction motor 9.

[0037] In one or more embodiments of the present invention, a gas sealing baffle 12 is movably provided in the discharge hopper 13, and the outer end of the discharge hopper 13 is connected to the dissolving tank.

[0038] In this embodiment, the air sealing baffle 12 is inserted in the middle of the discharge hopper 13. The material can start to enter the dissolving tank from the discharge port only after the air sealing baffle 12 is pulled out.

[0039] In one or more embodiments of the present invention, the silo 2 is fixed and supported by a plurality of legs 1 , and a weighing module 14 is arranged at the lower side of the legs 1 .

[0040] In this embodiment, the weighing module 14 adopts the existing technology, and its specific structure is not repeated here. The weight of the added material is displayed and monitored by the weighing module 14. When the material is added to a certain amount (process requirement), the addition is stopped to avoid blockage caused by excessive filling.

[0041] Working principle of this utility model:

[0042] The receiving points of the entire feeding device are all transmitted to the weighing module 14 at the bottom by the four legs 1. Before adding materials, the weighing module 14 should be adjusted to a critical state, and the air sealing baffle 12 at the discharge port should be in a closed state; when adding materials from the feeding hopper 7, the reduction motor 9 is in a closed state, and the weighing module 14 displays the weight of the added materials. When the material is added to a certain amount (process requirement), the feeding is stopped; at this time, the material is biased towards one side of the feeding hopper 7, and the material on the discharge side is less, such as Figure 1 As shown; when the drive motor is started, the material distribution impeller 4 starts to rotate, pushing the material on the higher side to the lower side. After 3 to 5 turns, the material surface in the silo gradually becomes smooth, as shown in FIG. Figure 2 As shown, a guarantee is provided for the smooth and steady discharge of the material; at this time, the air sealing baffle 12 is pulled out, and the material begins to enter the dissolving tank from the discharge port.
