Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick production, in particular to a device for uniformly adding anti-cracking high-temperature plastic explosion-proof fibers. Background Art

[0002] Refractory bricks are bricks made of refractory materials that have the characteristics of maintaining volume and strength at high temperatures, while having the ability to resist chemical erosion and physical wear. The production of refractory bricks usually includes the steps of raw material crushing, screening, mixing, molding (such as pressing or extrusion), drying and firing.

[0003] In workshop production, explosion-proof fibers need to be added to the screened plastics to improve their anti-burst and high-temperature resistance. However, in the actual adding process, the plastics are often added first and then the explosion-proof fibers, which will result in uneven mixing of the two, especially for the plastic powders added first and then later. The powders at the bottom are difficult to be spun up by the stirring paddle, so there is an uneven dispersion problem. Utility Model Content

[0004] In view of the deficiencies in the above prior art, the purpose of the utility model is to provide a device for uniformly adding anti-explosion high-temperature plastic explosion-proof fibers. Through the setting of the material guide box, the plastic and the explosion-proof fibers can be added at the same time and mixed in advance, and when the powder passes through the collision column, it will be splashed and dispersed to the surrounding powder, which greatly improves the mixing degree of the two powders; through the coordinated use of a hemispherical disperser, an oblique scraper and a stirring mesh plate, the raw materials entering successively are dispersed, the oblique scraper rotates the powder at the bottom, and the stirring mesh plate promotes the mixing of the powder, which greatly improves the mixing uniformity of the powder.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The anti-cracking high-temperature plastic explosion-proof fiber uniform adding device comprises a mixing box, a weighing box, a pre-storage tank, and a raw material storage tank. A material guide box is arranged above the mixing box, the weighing box is connected to the material guide box through the pre-storage tank, the raw material storage tank is connected to the material guide box through a pipeline, a primary material guide plate and a secondary material guide plate are arranged inside the material guide box, and a hemispherical disperser is arranged below the material guide box.

[0007] When the raw materials in the material guide box fall into the hemispherical disperser, they will disperse to the surroundings and fall into the mixing box.

[0008] The pre-storage tank is connected with a hot air blower, a connecting pipe between the hot air blower and the pre-storage tank goes deep into the bottom of the pre-storage tank, and an air outlet is arranged on the pre-storage tank.

[0009] The primary material guide plate is located above the secondary material guide plate, and a tertiary material guide plate is arranged below the primary material guide plate and the secondary material guide plate.

[0010] The primary guide plate and the tertiary guide plate are located on the side close to the raw material storage tank, and the secondary guide plate is located on the side close to the pre-storage tank. Both the secondary guide plate and the tertiary guide plate are provided with collision columns. When the powder slides down to the collision column on the guide plate by gravity, the powder will be splashed and dispersed to the surrounding powder.

[0011] A stirring paddle driven by a mixing motor is arranged inside the mixing box, and a stirring shaft is arranged between the stirring paddles driven by the mixing motor.

[0012] The stirring shaft is provided with an oblique scraper and a stirring mesh plate, and the oblique scraper is tangent to the bottom surface of the mixing box.

[0013] A supporting frame is arranged on the mixing box, and a material discharge port is arranged at the bottom of the mixing box.

[0014] The working principle of the utility model is:

[0015] Start the hot air blower to dry and purge the pre-storage tank. The explosion-proof fiber weighed by the weighing box enters the pre-storage tank, and then enters the guide box together with the plastic powder in the raw material storage tank; in the guide box, it is mixed by the first-level guide plate, the second-level guide plate and the third-level guide plate in turn, and then enters the mixing box through the hemispherical disperser. The mixing motor starts, and the stirring paddle, the oblique scraper and the stirring mesh plate start to rotate. After the mixing is completed, it enters the next device through the discharge port. Among them, when the powder slides down to the collision column on the guide plate by gravity, it will splash and disperse to the surrounding powder. The oblique scraper will spin up the powder at the bottom by rotation, and the stirring mesh plate will promote the mixing of the powder.
