Description

Technical Field

[0001] The utility model relates to a flame retardant storage tank, in particular to a flame retardant storage tank capable of recovering residual materials. Background Art

[0002] Flame retardant, a functional additive that gives flammable polymers flame retardancy, is mainly designed for the flame retardancy of polymer materials; there are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the method of use. Additive flame retardants are added to polymers by mechanical mixing to make polymers flame retardant. Additive flame retardants are mainly organic flame retardants and inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides) and non-halogen. Organic ones are some flame retardants represented by bromine, phosphorus nitrogen, nitrogen, red phosphorus and compounds, and inorganic ones are mainly flame retardant systems such as antimony trioxide, magnesium hydroxide, aluminum hydroxide and silicon. Flame retardant is a material with extremely fine particle size. It is easy to stick together when stored in a storage tank, causing blockage of the discharge. The existing flame retardant storage tank also has the disadvantage of inconvenient discharge. When discharge is required, the discharge of the storage tank is generally controlled by vibration, but the sound of the vibrator is loud, and the discharge speed is difficult to control. It is easy to adsorb on the inner wall of the storage tank, making it difficult to effectively remove the flame retardant remaining in the storage tank. Utility Model Content

[0003] The main purpose of the present disclosure is to provide a flame retardant storage tank capable of recycling residual materials, so as to effectively solve the problems raised by the inventor in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A flame retardant storage tank capable of recovering residual materials comprises a storage tank with a hemispherical bottom and a screw feeder, wherein the screw feeder is located below the storage tank, and a discharge port at the bottom of the storage tank is aligned with a feed port of the screw feeder, an inner middle column is fixedly connected to an inner top wall of the storage tank, two annular scrapers distributed in upper and lower positions are slidably mounted on the inner middle column, a docking rod is fixedly connected between the two annular scrapers, and the outer sides of the annular scrapers are in contact with the inner wall of the storage tank.

[0006] Preferably, a rotating shaft is rotatably mounted on the lower end of the inner center column, a fan-shaped scraper is fixedly mounted on the rotating shaft, and the outer side of the fan-shaped scraper contacts the inner wall of the hemispherical part of the storage tank.

[0007] Preferably, a gear is fixedly mounted on the rotating shaft, and a vertical rack is fixedly connected to the bottom of the annular scraper below, and the vertical rack is meshed with the gear.

[0008] Preferably, a Y-axis slide rail is provided on the inner center column, a Y-axis screw rod is rotatably installed in the Y-axis slide rail, a servo motor is fixedly installed on the top of the storage tank, and the output end of the servo motor is fixedly connected to the top of the Y-axis screw rod, and a translation key is fixedly connected to the inner side of the annular scraper below, and the translation key is threadedly installed on the Y-axis screw rod and slides in the Y-axis slide rail.

[0009] Preferably, the center of the rotation axis coincides with the center of the hemispherical part of the storage tank.

[0010] Preferably, a feed hopper is provided at the upper end of the storage tank.

[0011] In view of this, compared with the prior art, the beneficial effects of the utility model are:

[0012] (i) In the present application, the flame retardant is fed into the storage tank from the feed hopper for storage. When discharging, the screw feeder is turned on to allow the material in the storage tank to fall into the feed port of the screw feeder through the discharge port, and the material is discharged and transported by the screw feeder. When the material in the storage tank is used up, the servo motor drives the Y-axis screw to rotate, so that the two annular scrapers move up and down in the storage tank, and then the residual material on the inner wall of the storage tank is scraped off to recycle the remaining material for standby use, thereby avoiding waste and reducing the accumulation of material on the inner wall of the storage tank.

[0013] (ii) In the present application, during the movement of the annular scraper, the vertical rack moves accordingly. Since the gear on the rotating shaft is meshed with the vertical rack, the rotating shaft drives the fan-shaped scraper to swing. The fan-shaped scraper cleans the inner wall of the lower end of the storage tank, making the cleaning more complete. The middle of the fan-shaped scraper and the annular scraper are hollowed out, so that the material can fall smoothly and avoid accumulation of material in the storage tank.
