Abstract
Description
Technical Field
[0001] The present application relates to the technical field of foam glass production equipment, and in particular to a heat insulation device for foam glass entering a kiln. Background Art
[0002] Foam glass is a porous glass material made of a certain amount of broken glass, foaming agent, modifying additives and accelerators, which are finely crushed and evenly mixed to form a batch, put into a specific mold, and then made into a porous glass material through preheating, melting, foaming, annealing and other processes. Foam glass is a lightweight, high-strength building material and decorative material with excellent performance in heat insulation, sound absorption, moisture resistance and fire resistance. It has the advantages of high mechanical strength, low thermal conductivity, low thermal expansion coefficient, no water absorption, no moisture permeability, stable thermal performance, no combustion, no deformation, long service life, wide operating temperature range, pest prevention, good corrosion resistance, easy processing and cutting, and extremely convenient construction. Foam glass is widely used in petroleum, chemical industry, cold storage, underground engineering, advanced construction, national defense and military industry and other fields. Foam glass has a wide range of uses, obvious energy saving and economic effects, and is a high-performance green and environmentally friendly insulation material.
[0003] At present, in the production process of foam glass, the foamed foam glass blank needs to be sent to the annealing kiln for effective annealing treatment. If it cannot be annealed properly, quality problems such as breakage, dents, and dark cracks will occur. The foamed foam glass blank has a high heat value and a significant heat difference with the external environment, which can easily produce rapid heat exchange. Especially when a large number of foam glass blanks are sent to the kiln mouth of the annealing kiln, the kiln mouth is always connected to the external environment, causing the foam glass to exchange heat rapidly with the external environment, resulting in a faster annealing process of the foam glass blank, which can easily cause product quality problems and lead to waste of resources.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.
[0031] The embodiment of the present application discloses a heat insulation device for feeding foam glass into a kiln.
[0032] Reference Figure 1 , a heat insulation device for foam glass entering a kiln includes an annealing furnace 2 for annealing a foam glass blank 1, and the foam glass blank 1 can be slowly conveyed along the length direction of the annealing furnace 2, and hot air circulates in the annealing furnace 2, so that the foam glass blank 1 can be slowly annealed in the annealing furnace 2, and a rectangular kiln opening 21 is opened at one end of the annealing furnace 2, and an insulation door panel 3 and a sliding component 4 are installed at the kiln opening 21, and the number of the insulation door panels 3 is multiple, and the multiple insulation door panels 3 are evenly arranged in the width direction of the annealing furnace 2, and the multiple insulation door panels 3 can jointly block the kiln opening 21, and by adjusting the positions of the insulation door panels 3 in sequence, opening the corresponding kiln entry channels, the foam glass blanks 1 entering the annealing furnace 2 are arranged regularly, and the gaps between the foam glass blanks 1 are kept consistent, so that the hot air flow circulation in the annealing furnace 2 is more uniform and smooth, and the heat exchange of the foam glass blank 1 is more sufficient and reasonable, shortening the annealing time, effectively improving the quality of the product, reducing the heat loss of the foam glass blank 1, and reducing the energy consumption of the annealing furnace 2.
[0033] The heat-insulating door panels 3 are square panels of the same width, and the heat-insulating door panels 3 and the sliding assembly 4 are both made of high-temperature resistant alloy materials, which have good high-temperature resistance and ensure their service life.
[0034] A push plate 31 is vertically fixed to the middle end of each heat insulation door panel 3 , and the push plate 31 facilitates an operator to slide each heat insulation door panel 3 in sequence.
[0035] The sliding assembly 4 includes a sliding plate 41, and a sliding plate 41 is fixed to the upper end of each heat-insulating door panel 3. Two pulleys 42 are rotatably installed on the upper end of each sliding plate 41. Two mounting shafts 43 arranged parallel to each other are vertically fixed to the upper end of the sliding plate 41. The pulleys 42 and the mounting shafts 43 are arranged one by one opposite to each other, and the mounting shafts 43 pass through the axis of the pulley 42, so that the pulley 42 is rotatably installed on the outside of the mounting shafts 43.
[0036] The circumferential surface of each pulley 42 is provided with an annular groove 421. A horizontally arranged fixed guide rail 22 is fixed on the annealing furnace. The cross-sectional shape of the groove 421 is fitted with the cross-sectional shape of the fixed guide rail 22, so that the pulley 42 can slide stably along the length direction of the fixed guide rail 22. The fixed guide rail 22 is located above the kiln mouth 21, and the length direction of the fixed guide rail 22 is parallel to the width direction of the annealing furnace 2.
[0037] Each heat-insulating door panel 3 is slidably mounted on the fixed guide rail 22 via a pulley 42.
