Description

Technical Field

[0001] This utility model relates to the field of kiln technology, and in particular to a production equipment for continuous production of sintered antique building materials and red bricks. Background Technology

[0002] Currently, antique-style building materials are mainly produced in small, scattered kilns across the country. These kilns have low production capacity, long production cycles, high energy waste, serious pollution, and cannot be produced continuously. The average cost for standard bricks is between 0.8 and 1.2 yuan. There are also shuttle kilns that use natural gas, with a cost between 0.6 and 1 yuan. These kilns also cannot be produced continuously due to their intermittent production, resulting in significant heat loss and high heat consumption from both heat storage and dissipation. Additionally, there are roller kilns, which are suitable for tile production due to the material of the rollers. The cost for producing blue bricks is also between 0.8 and 1 yuan.

[0003] Developing a production equipment for the continuous production of sintered antique-style building materials and red bricks, without the need for adding water, gas, or combustible powder for oxygen isolation, and without the need for gas exchange, thus simplifying the manufacturing process and reducing costs, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a production equipment for continuous production of sintered antique building materials and red bricks, thereby solving the problems listed in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a production equipment for continuous production of sintered antique building materials and red bricks, including a kiln car. A brick blank is placed on the upper surface of the kiln car, and a cover is covered on the outer periphery of the brick blank. The lower opening of the cover abuts against the upper surface of the kiln car.

[0007] The upper surface of the cover is fixedly equipped with lifting lugs;

[0008] A hoisting assembly is installed across the upper surface of the kiln car along the kiln exit path, and the hoisting assembly is connected to the lifting lug.

[0009] Preferably, a sealing filler is placed between the upper surface of the kiln car and the contact surface of the cover opening.

[0010] Preferably, the sealing filler is sand or soil.

[0011] Preferably, the lower opening of the cover is provided with a receiving groove, and fireproof cotton or asbestos is placed inside the receiving groove.

[0012] Preferably, the hoisting assembly includes a frame, and a hoisting trolley is movably mounted on top of the frame. The hoisting trolley is connected to the lifting lug via slings.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model relates to a production equipment for the continuous production of sintered antique-style building materials and red bricks. By sealing the brick blanks with a cover installed on the kiln car, there is no need to add water, gas, or combustible powder for oxygen isolation, nor is there a need for air exchange. Simply sealing the cover is sufficient, making the process simpler. The production cost is calculated based on standard bricks, with a cost of only 0.2-0.4 yuan, effectively reducing costs. It can also produce continuously to increase output and can be mixed and fired with red bricks according to market demand, allowing for free switching. Attached Figure Description

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] like Figure 1-5 As shown, a production equipment for continuous production of sintered antique building materials and red bricks includes a kiln car 1, on the upper surface of the kiln car 1, a cover 2 covering the outer periphery of the brick blank, and the lower opening of the cover 2 abutting against the upper surface of the kiln car 1.

[0024] The upper surface of the cover 2 is fixedly equipped with a lifting lug 3;

[0025] A hoisting assembly is installed across the upper surface of the kiln car 1 along the kiln exit path, and the hoisting assembly is connected to the lifting lug 3.

[0026] Specifically, a sealing filler is placed between the upper surface of the kiln car 1 and the contact surface of the opening of the cover 2. The powder can fill the gap between the contact surface of the cover and the kiln car to ensure the sealing effect.

[0027] Specifically, the sealing filler is made of non-combustible materials such as sand or soil.

[0028] Specifically, the lower opening of the cover 2 is provided with a receiving groove 4, and fireproof cotton or asbestos is placed inside the receiving groove 4. The cover can maintain a sealing device with the upper surface of the kiln car through the flexible materials such as fireproof cotton or asbestos inside the receiving groove.

[0029] Specifically, the hoisting assembly includes a frame 5, on which a hoisting trolley 7 is movably mounted. The hoisting trolley 7 is connected to the lifting lugs 3 via slings 6, enabling the covering and removal of covers on the brick blanks, ensuring the continuity of the brick blank firing process.

[0030] The process of making, drying and firing antique-style building materials is the same as that of red bricks. They are fired to about 950°C. Starting from the annealing section, an opening is made on the corresponding kiln surface, and a sliding top cover is made to facilitate the lifting trolley to close the cover. The cover is closed at 600°C to 800°C. After being taken out of the kiln, it is placed to cool naturally to obtain antique-style building materials.

[0031] This allows brick blanks from the same kiln car to be converted into antique-style building materials and red bricks by covering them after they leave the kiln.

[0032] Example 1

[0033] The bottom of the cover is sealed with fine powder. When the cover is placed above 600°C and the kiln is opened after 12 hours, the cover temperature is around 230°C. At this time, the powder under the cover is blown open, and bubbles rise from the powder. The air pressure inside the cover is kept positive, so there is no need to add other oxygen-barrier substances, such as water, water vapor, carbon dioxide, or gases after air combustion. In addition, when the brick blank is covered, there is still a small amount of unburned carbon. After the cover is placed, the air inside the cover will help consume the oxygen. By sealing the contact surface between the cover and the kiln car, the annealing section temperature is above 600°C when the cover is placed, resulting in a stable yield of over 99%.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
