Description

Technical Field

[0001] The utility model relates to the technical field of kilns, in particular to an energy-saving kiln roof thermal insulation structure of a foamed ceramic drying kiln. Background Art

[0002] Foamed ceramic insulation board is a high-porosity closed-cell ceramic material made of clay tailings, ceramic fragments, river silt, adulterated materials, etc. as the main raw materials, using advanced production technology and foaming technology and high-temperature roasting. The product is suitable for building exterior wall insulation, fire isolation belts, building self-insulation hot and cold bridge treatment, etc. It has the advantages of fire retardancy, small deformation coefficient, aging resistance, stable performance, good ecological and environmental protection, good compatibility with wall base and plastering layer, good safety and stability, and can have the same lifespan as the building. More importantly, the material has a fire resistance grade of A1, which overcomes the fatal weaknesses of organic materials that are afraid of open flames and easy to aging, and fills the domestic gap in building inorganic insulation materials.

[0003] In the production process of foamed ceramics, firing often requires the use of special kilns. For this reason, many new kiln insulation structures have emerged. For example, the prior art CN209131401U is a roller kiln roof insulation structure, including a kiln body, a refractory brick is arranged on the top of the kiln body, a first insulation layer is laid above the refractory brick, a second insulation layer is laid above the first insulation layer, the upper end of the second insulation layer is flush with the ground, a foamed ceramic plate is arranged above the second insulation layer, and the foamed ceramic plate is crimped to the second insulation layer.

[0004] There are other existing technologies:

[0005] CN203964643U, a new type of daily-use porcelain tunnel kiln roof insulation structure;

[0006] CN204730638U, a top load-bearing and heat-insulating structure of a push-plate kiln.

[0007] The structure mentioned in the above-mentioned prior art improves the thermal insulation performance of the kiln by making improvements in materials. However, in actual use, although the thermal insulation effect has been improved to a certain extent, the hot air itself is mostly gathered at the top of the kiln due to its own properties, causing a temperature difference between the top and bottom of the kiln and uneven temperature inside the kiln. In addition, the kiln is generally not ventilated, and the water vapor generated by the firing of the product cannot be discharged, making it difficult to control the humidity of the kiln, which will have a certain impact on the firing success rate of the product.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1 The utility model provides a technical solution: an energy-saving kiln roof insulation structure of a foamed ceramic drying kiln.

[0025] Among them, a support frame 101 is fixedly connected to the inside of the kiln roof 1 near the left and right sides, an air inlet 102 is arranged on one side of the support frame 101, a guide plate 104 is fixedly connected to the center position of the kiln roof 1, an auxiliary heating structure 2 is arranged on the top of the support frame 101 near the side wall of the kiln roof 1, an electric heating wire 201 is arranged inside the auxiliary heating structure 2, a filtering structure 4 is arranged on the top of the support frame 101 near the guide plate 104, a filtering sponge 401 is arranged inside the filtering structure 4, a circulation structure 3 is arranged between the auxiliary heating structure 2 and the filtering structure 4, and a fan 301 is arranged inside the circulation structure 3.

[0026] In this embodiment, the support frame 101 is fixed on the kiln wall. The support frame 101 and the auxiliary heating structure 2, the circulation structure 3 and the filtering structure 4 are all provided at two locations. The guide plate 104 at the center of the kiln top 1 is symmetrical with the center line. The gap between the support frame 101 and the kiln wall is the air inlet 102. The auxiliary heating structure 2 is composed of a plurality of fans 301. The rotation of the fans 301 generates an air pressure difference, and the air at the bottom of the kiln is sucked through the auxiliary heating structure 2. The electric heating wire 201 on the auxiliary heating structure 2 heats the airflow to reduce the heat generated by the airflow movement. The air passes through the filter structure 4 through the circulation structure 3. The filter sponge 401 on the filter structure 4 can absorb water vapor in the air, so that the air in the kiln remains dry. After passing through the filter structure 4, the air is blown to the guide plate 104, and the airflow direction is changed by the guide plate 104, so that it returns downward to the bottom of the kiln to form a circulation. The two support frames 101 cooperate with the multiple structures on the support frames 101 to form two circulations in the kiln, so that the hot air in the kiln no longer gathers at the top, and the temperature in the kiln becomes uniform.

[0027] A control box 5 is arranged on the left side of the kiln roof 1 , a motor 501 is arranged on the top of the control box 5 , a cable 502 is arranged on the inner wall of the kiln roof 1 , and the auxiliary heating structure 2 and the circulation structure 3 are connected to the control box 5 through the cable 502 .

[0028] In this embodiment, the control box 5 starts the motor 501, and transmits the electricity generated by the motor 501 to the auxiliary heating structure 2 and the circulation structure 3 through the cable 502 to power them. The current passes through the electric heating wire 201 to make it heat up, and the current passes through the fan 301 to drive the fan to rotate and blow air.

[0029] Among them, a handrail 103 is fixedly connected between two support plates 101 on the inner wall of the kiln roof 1.

[0030] In this embodiment, the operator can climb to the height of the support frame 101 through the handrail 103 to repair the structure above the support frame 101. At the same time, after the filter structure 4 has been filtering for a long time, the filter sponge 401 will absorb more water, thereby reducing the absorption effect. It is convenient to replace it by climbing the handrail 103.

[0031] A plurality of through holes 402 are formed on the surface of the filter sponge 401 .

[0032] In this embodiment, the efficiency of air passing through the filter sponge 401 is increased through the through hole 402. When the moisture in the air passes through the through hole 402, it contacts the filter sponge 401 and is adsorbed, so that the filter sponge 401 still has a certain drying effect.

[0033] The left and right sides of the guide plate 104 are arc-shaped.

[0034] In this embodiment, the guide plate 104 can change the direction of the wind blowing from the support frame 101, and the wind originally blown toward the center of the kiln top 1 through the fan 301 is transformed into wind blowing toward the kiln bottom, so that a flow circulation is formed in the kiln, and the curved surface makes the turning smoother.

[0035] Wherein, a heat-insulating layer 105 is arranged in the inner wall interlayer of the kiln roof 1 .

[0036] In this embodiment, the insulation layer 105 is a foamed ceramic structure, which has a certain insulation effect, so that the kiln can maintain a certain temperature, and the overall cooling rate is slowed down, thereby reducing the heat energy generated in the kiln to increase the temperature and saving heating costs.

[0037] Working principle: the control box 5 starts the motor 501, drives the fan 301 to rotate through the cable 502, and drives the electric heating wire 201 on the auxiliary heating structure 2 to start generating heat. The fan 301 rotates to generate air pressure difference, and the air at the bottom of the kiln is sucked in through the air inlet 102, passes through the electric heating wire 201 for heating and heat preservation, so as to reduce the heat loss during air flow. The air passes through the filter structure 4, and the filter sponge 401 on the filter structure 4 absorbs the moisture in the air to keep the air dry. The wind blown out by the fan 301 is turned through the guide plate 104 and moves to the middle position of the kiln bottom, thereby forming a cycle in the kiln, so that the hot air will not be stored at the top of the kiln all the time. When the product in the kiln is dried, the moisture evaporates into water vapor through high temperature, and then is absorbed by the filter structure 4, producing the effect of drying the product.
