AI Technical Summary
In the production of refractory bricks, the primary fermentation of powder refractory plastics leads to incomplete crystal growth and requires secondary fermentation. However, this process requires high-temperature heating, resulting in waste of energy, and the secondary development is affected by the uneven development of large particles.
A refractory plastic secondary fermentation device is designed. By setting a heat exchanger in the secondary development tank, the waste heat of the heating furnace flue gas is used for insulation, reducing heating energy consumption; at the same time, a decontamination filter is set up in the primary development products to screen large particles and impurities to ensure the normal progress of secondary development.
By using the waste heat of flue gas for insulation, the heating energy consumption is greatly reduced; the impurity removal filter effectively removes large particles and improves the quality and efficiency of secondary development.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refractory brick production, in particular to a refractory plastic secondary fermentation device. Background Art
[0002] Refractory bricks are a type of ceramic material used in high-temperature industrial applications, primarily in the construction and maintenance of various types of high-temperature furnaces, kilns, and other heat treatment equipment. Their main function is to withstand high temperatures, chemical corrosion, and physical wear. The manufacture of refractory bricks typically involves the mixing, molding, drying, and sintering of raw materials. During the sintering process, the microstructure and physical properties of the material change, thereby improving its refractory properties.
[0003] In actual production, the powdered refractory plastic needs to be fermented to promote and stabilize the crystal formation. However, the first fermentation has the problem of incomplete crystal growth, so a second fermentation is needed. However, in workshop production, the second fermentation requires a certain temperature (40-45℃), and needs to be continuously heated, which wastes a certain amount of energy. In addition, during the first fermentation, due to uneven development, there are some larger particles, which seriously affect the normal development of the second fermentation. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a refractory plastic secondary fermentation device. Through the setting of a heat exchanger, the waste heat of the heating furnace flue gas is used to keep the secondary development tank warm, greatly reducing the heating energy consumption; through the setting of an impurity removal filter, the powder produced by the primary development is filtered to remove large particles of impurities, thereby avoiding the impact on the secondary development.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] The fire-resistant plastic secondary fermentation device comprises a primary development tank, which is connected to a secondary development tank through a decontamination filter, a secondary development tank insulation coil is arranged inside the secondary development tank, a heat exchanger is connected to the secondary development tank insulation coil, a filter plate is arranged inside the decontamination filter, and a hemispherical bulk material distributor is arranged inside the secondary development tank. A vibrator is arranged on the decontamination filter.

[0008] The heat exchanger is provided with a heat preservation water inlet pipe, and a secondary development tank heat preservation coil inlet pipe is provided between the heat exchanger and the secondary development tank heat preservation coil.
[0009] An obtuse-angled discharger is arranged below the primary development tank, and the obtuse-angled discharger is connected to the impurity removal filter through a pipeline, and the connection between the obtuse-angled discharger and the impurity removal filter is located above the filter plate.
[0010] The impurity removal filter is provided with a scraper driven by a driving motor inside, the lower edge of the scraper is tangent to the upper surface of the filter plate, and the impurity removal filter is provided with an impurity discharge port, which is located above the filter plate. The scraper reduces the arching of the powder by rotating, and at the same time guides the large particles to the impurity discharge port.
[0011] The secondary development tank is provided with a secondary development tank feed port, which is connected to the bottom of the impurity removal filter through a pipeline, and the hemispherical bulk feeder is located directly below the secondary development tank feed port. The powder entering through the secondary development tank feed port falls freely to the hemispherical bulk feeder by gravity, and then dispersed into the secondary development tank, thereby improving the dispersion degree of the front and rear added materials.
[0012] The interior of the secondary development tank is provided with a stirring paddle driven by an intermittent stirring motor, and the insulation coil of the secondary development tank is connected with a pipeline exiting the insulation coil of the secondary development tank.
[0013] The intermittent stirring motor drives the stirring paddle to rotate intermittently to avoid the influence of continuous rotation on the crystal growth.
[0014] The working principle of the utility model is:
[0015] The first-stage development tank processes the refractory plastic first, and the flue gas in the heating furnace enters the heat exchanger to heat the insulation water, and then the insulation water enters the insulation coil of the second-stage development tank to heat the second-stage development tank; the refractory plastic developed in the first-stage development tank enters the impurity removal filter through the blunt-angle discharger, and the drive motor drives the scraper to start working, and the refractory plastic with large particles is screened out enters the second-stage development tank, and the intermittent stirring motor drives the stirring paddle to start working. Among them, the scraper reduces the arching of the powder by rotating, and at the same time guides the large particles into the impurity discharge port. The intermittent stirring motor drives the stirring paddle to rotate intermittently to avoid the influence of continuous rotation on the growth of the crystal form.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
