Description

TECHNICAL FIELD

[0001] The utility model relates to baking equipment technical field, specifically, relate to a baking house. BACKGROUND

[0002] In the construction process, baking construction materials can affect the construction quality and material performance. Many construction materials such as cement, concrete, bricks, etc. will absorb some moisture during production or storage. Baking can effectively remove these moisture to prevent structural cracks or shrinkage problems caused by moisture evaporation during construction. Baking can also promote the chemical reaction inside the material, such as the hydration of cement, thereby improving the strength and hardness of the material.

[0003] However, baking construction materials can produce harmful gases. These gases mainly come from the decomposition and volatilization of additives, adhesives and other chemical components in construction materials at high temperatures, thereby producing harmful gases such as formaldehyde, VOCs, ammonia and hydrogen sulfide.

[0004] The existing baking device is difficult to ensure the successful baking of construction materials with surface coatings because uneven heating can cause shrinkage and cracking of construction materials, resulting in coating rupture. Moreover, harmful gases after baking cannot be purified, and there is no environmental protection.

[0005] The Chinese utility model patent with the patent name "Foundry sand mold baking house" and the announcement number CN203917822U has been disclosed. The patent includes a baking house composed of a wall and a sealing door, a heating furnace, a hot air pipe and an exhaust pipe. The heating furnace is located outside the baking house and is connected to one end of the hot air pipe. The other end of the hot air pipe is connected to the space inside the baking house. One end of the exhaust pipe is located at the bottom of the baking house, and the pipe body is provided with air holes connected to the space inside the baking house. The other end of the exhaust pipe is connected to the outside space. The device can uniformly heat the foundry sand mold, has good drying effect and high drying efficiency.

[0006] Although the device can uniformly bake, the hot air is still directly blown to the surface of the product, and it cannot purify the harmful gases produced by some products. It can only be used for the baking of some rough construction materials, which has certain limitations. UTILITY MODEL CONTENT

[0032] Embodiment

[0033] Please refer to Figures 1-5 The utility model provides a kind of baking house, including baking house 1, fan 2, heating machine 3, air pipe structure 4, baffle 5, guide plate 6, baking frame 7, waste gas filtering structure 8.

[0034] Further, the baking house 1 is responsible for providing a closed baking environment for the construction materials to be baked. The baking house 1 includes a baking area 101 and a hot air area 102.

[0035] The hot air area 102 is located above the baking area 101 and belongs to two independent chambers. The heating machine 3 and the fan 2 are fixedly arranged in the hot air area 102. The fan 2 and the heating machine 3 are connected to the air pipe structure 4. The air pipe structure 4 is blown and heated by the fan 2 and the heating machine 3, so as to blow out hot air. The baking frame 7 is arranged in the baking area 101. The hot air blown out from the hot air area 102 enters the baking frame 7 in the baking area 101 to perform the baking function.

[0036] Among them, fan assembly is included in fan 2, and electric heating wire is included in heating machine 3. Both of them belong to conventional equipment mastered by existing field technicians, so they are not described in detail in the specification.

[0037] Further, the air pipe structure 4 includes a blowing pipe 401 and an air duct 402.

[0038] The blowing pipe 401 is vertically arranged in the drying room 1, the top of the blowing pipe 401 is communicated with the fan assembly of the fan 2 and the electric heating wire of the heating machine 3, the hot air is blown from the top of the blowing pipe 401 to the bottom of the blowing pipe 401, the bottom of the blowing pipe 401 is close to the bottom surface in the drying room 1, the hot air is blown to the bottom of the drying room 1, the pipe of the blowing pipe 401 is vertically arranged in the center of the baking rack 7, the pipe of the blowing pipe 401 at the baking rack 7 is vertically penetrated by a plurality of air ducts 402, and the hot air is blown to the inner side of the baking rack 7.

[0039] Preferably, the hot air blown by the blowing pipe 401 promotes the air flow in the drying room 1, exchanges the hot air, and makes the temperature in the drying room 1 rapidly rise, the blowing outlets at different positions of the blowing pipe 401 make the hot air more uniformly dispersed to each part of the baking rack 7, uniformly heats the construction materials placed on the baking rack 7, prevents the construction materials at different positions from being heated to different degrees, causes the color of the surface coating of part of the construction materials to be inconsistent, causes the construction materials to be peeled and cracked, and affects the baking quality.

[0040] Further, the pipe of the blowing pipe 401 is provided with the baffle 5, the baffle 5 is located directly above the baking rack 7, the baking rack 7 is located in the shadow range projected by the upper baffle 5, the pipe of the blowing pipe 401 above the baffle 5 also has the air duct 402, the air outlet of the air duct 402 needs to be sent to the outside of the baking rack, so that the overall temperature in the drying room is uniformly raised. If the baffle 5 is not arranged, the hot air with a large flow rate blown by the air duct 402 will directly blow into the construction materials on the top surface of the baking rack 7, causing the construction materials to be overheated and cracked. Therefore, the baffle is arranged to block the flow, and the hot air is guided to the outside of the baking rack 7 and continues to flow downward. At this time, the hot air will be blown to the guide plate 6.

[0041] A plurality of guide plates 6 are vertically arranged on the inner wall of the drying room 1, there is an included angle between the surface of the guide plate 6 and the inner wall of the drying room 1, the included angle ranges from 0 degrees to 90 degrees (different included angle guide plates 6 can be installed according to different blowing strength requirements), and the lower end of the guide plate 6 is close to the outside of the baking rack 7, so that the hot air blown to the guide plate 6 is guided to the outside of the baking rack 7, and the outside of the construction materials on the baking rack 7 is dried by the hot air.

[0042] Preferably, the transverse air duct 402 arranged on the blowing pipe 401 and the baffle 5 and the guide plate 6 arranged outside can make the blown hot air not directly blow to the surface of the construction materials on the baking rack 7, cause the construction materials to be unevenly heated and cause the construction materials to be cracked, make the flow rate of the hot air guided by different guide angles greatly reduced, and the hot air can be more gently blown to the surface of the construction materials on the baking rack 7, and the hot air is blown by synchronous guide at different positions, and the baking is more uniformly heated, so that the baking quality is ensured.

[0043] Further, the bottom of the curing room 1 is communicated with a waste gas filtering structure 8. Because of the surface coating of the construction material or the material itself, part of the harmful substances will evaporate with the moisture during the baking process, and harmful gas will be generated. If the gas is directly discharged, it will endanger the environment and personnel safety. Therefore, the waste gas needs to be filtered and purified.

[0044] The waste gas filtering structure 8 includes a gas outlet pipe 801, a gas pump assembly 802, a filtering box 803, a communication pipe 804, a washing box 805, and an activated carbon filter layer 806.

[0045] The gas pump assembly 802 is arranged on the gas outlet pipe 801. The gas outlet pipe 801 is communicated with the inside of the curing room 1 and the inside of the filtering box 803. The gas pump assembly 802 pumps the harmful gas in the curing room 1 into the filtering box 803. The filtering box 803 is provided with a filter screen. When the harmful gas passes through the filter screen, the dust and particulate harmful substances will be filtered out.

[0046] One end of the communication pipe 804 connected to the filtering box 803 is located at the filter screen. The other end of the communication pipe 804 is communicated with the bottom of the washing box 805. The washing box 805 is filled with a washing solution. The harmful gas after the filter screen is discharged into the washing solution, and part of the harmful substances are neutralized by the washing solution (for example, the washing solution is set as water or alkaline solution, and the acidic substances such as sulfur dioxide and hydrogen chloride in the harmful gas are neutralized).

[0047] The activated carbon filter layer 806 is arranged on the top of the washing box 805. The top surface of the washing box 805 is provided with air holes. The gas after washing is introduced into the activated carbon filter layer 806, and the harmful substances in the harmful gas are adsorbed again. Then, the purified gas is discharged from the air holes to the external environment, so as to ensure the environmental protection during the baking.

[0048] Please refer to Figure 3 In the embodiment, the air pipe structure 4 further includes an air inlet pipe 403 and a valve assembly 404. Specifically, the blowing pipe 401 is provided with two air inlets. One air inlet is communicated with the air outlet of the air blower. The other air inlet is communicated with one end of the air inlet pipe 403. The other end of the air inlet pipe 403 is communicated with the external environment. The air inlet of the air blower 2 is located in the baking area of the curing room 1. The air inlet pipe 403 is provided with the valve assembly 404.

[0049] When the hot air blowing pipe blows hot air by the fan 2 and the heating machine 3, the valve assembly 404 closes the air inlet pipe 403, at this time, the hot air in the curing room 1 is self-circulated, avoiding the loss of hot air, improving the baking efficiency, when the baking is completed, the heating machine 3 is closed, the fan 2 is still working, at this time, the valve assembly 404 is controlled to open, so that the external environment is connected with the hot air blowing pipe 401 through the air inlet pipe 403, the fan 2 blows the external cold air into the curing room 1 by the blowing negative pressure, the cold and hot air exchanges heat (at this time, the air pump assembly 802 in the waste gas filtering structure 8 also starts to work, avoiding the hot air containing harmful gas from the air inlet pipe 403 to the outside, causing harmful gas leakage), accelerating the temperature reduction in the curing room 1, so that the workers can quickly take out the baking completed construction building materials, improving the work efficiency.

[0050] Please refer to Figures 1-3 In the embodiment, the baking rack 7 comprises a rack body 701 and a rotating ring 702.

[0051] Specifically, the rack body 701 is a structure formed by vertically abutting a plurality of annular rack plates, facilitating the placement of multiple layers of construction building materials for baking, and the center of the annular rack plate is the vertical pipe of the hot air blowing pipe 401; the bottom of the rack body 701 is fixedly connected with the rotating ring 702, and the rotating ring 702 is rotatably arranged at the bottom of the curing room 1. The rotating ring 702 enables the workers to rotate the rack body 701 when placing the construction building materials on the rack body 701, and the construction building materials are placed at the entrance of the curing room 1.
