Description

Technical Field

[0001] The utility model relates to the technical field of double-layer electric heating roller kilns, in particular to a cascade-type fully automatic double-layer electric heating roller kiln. Background Art

[0002] Electric kilns are widely used in the sintering of structural ceramics, functional ceramics, phosphors, rare earth materials, lithium battery materials (lithium cobalt oxide), magnetic materials, nanomaterials and other products. With the advancement of technology, in addition to traditional single-channel electric kilns, double-layer kilns have also appeared.

[0003] The fully automatic double-layer electric heating roller kiln is a type of double-layer kiln. Although this type of kiln is more energy-efficient and efficient, in traditional double-layer kilns, the middle layer between the upper and lower kilns is the bottom layer of the upper kiln and the top layer of the lower kiln. The middle layer may have uneven temperature due to heat radiation from the upper and lower layers, resulting in thermal stress concentration in the higher temperature area. The thermal stress cannot be evenly distributed on the entire insulation layer, thereby reducing material damage caused by thermal stress concentration, such as cracks and peeling. In order to solve the above problems, we proposed this tandem fully automatic double-layer electric heating roller kiln. Utility Model Content

[0004] The main purpose of the utility model is to provide a tandem type fully automatic double-layer electric heating roller kiln, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A stacked, fully automatic, double-layer, electrically heated roller kiln comprises a lower kiln and an upper kiln. Both side walls of the upper kiln are provided with mounting frames.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, a stacked fully automatic double-layer electric heating roller kiln includes a lower kiln 1 and an upper kiln 2. The lower kiln 1 and the upper kiln 2 are kilns in the prior art, and the electric heating components therein are not marked in the figure. Mounting frames 6 are provided on both side walls of the upper kiln 2. A plurality of heat-insulating mechanisms for blocking heat are provided between the lower kiln 1 and the upper kiln 2. The heat-insulating mechanisms include a plurality of partition boxes 3 arranged at the upper end of the lower kiln 1, and an insulation layer 11 is provided in the partition box 3.

[0025] The side wall of the partition box 3 is provided with a cooling mechanism for lowering the temperature of the liquid in the partition box 3. The cooling mechanism includes a mounting plate 8 and a liquid storage tank 12 arranged on both side walls of the partition box 3. A circulating pump 4 is provided on the mounting plate 8. The water outlet end of the circulating pump 4 is connected to a water outlet pipe 5. A controller 14 is provided on the liquid storage tank 12.

[0026] In the present invention, the liquid storage tank 12 is provided with a mounting seat, on which a heat exchanger 15 is provided, which can cool the heating oil returning to the liquid storage tank 12 when the temperature in the liquid storage tank 12 is high, thereby reducing the temperature of the heating oil in the circulation loop.

[0027] In the present invention, a temperature sensor 9 is provided on the side wall of the partition box 3, and a control panel 13 is provided on the side wall of the liquid storage tank 12, which can monitor the temperature of the heating oil in the partition box 3. After the kiln has worked for a long time and multiple times, when the temperature rises, the circulation pump 4 is automatically started.

[0028] In the present invention, a plurality of partitions 10 are fixedly connected to the bottom of the partition box 3, and a plurality of support plates are fixedly connected to the bottom of the partition box 3, which can make the structural strength of the partition box 3 higher and will not easily collapse due to the hollowness in the middle.

[0029] In the utility model, the upper end of one of the mounting frames 6 is fixedly connected to a fixing frame 7, the top of the fixing frame 7 is fixedly connected to an electric slide rail 19, a movable plate 16 is provided under the electric slide rail 19, and a plurality of electric hoists 17 are fixedly connected to the lower end of the movable plate 16. The output line of the electric hoist 17 is provided with a hook 18, which can be used to hoist the shelves on the upper kiln 2 to the ground, making it more convenient to place porcelain to be fired on the shelves.

[0030] In the initial state, cargo racks are provided in the lower kiln 1 and the upper kiln 2.

[0031] It should be noted that the present invention is a tandem, fully automatic, double-layer electrically heated roller kiln. The user fills the partition box 3 with heating oil and the partition box 3 made of heat-insulating material to separate the lower kiln 1 from the upper kiln 2. This partition layer exists between the lower kiln 1 and the upper kiln 2. The thermal insulation layer 11 in the partition layer can effectively prevent the heat of the upper and lower kilns from being directly transferred to the middle layer of the traditional kiln. This not only helps to control the temperature of the middle layer, but also reduces heat loss and improves the energy efficiency of the kiln. From the perspective of service life, good thermal insulation performance can reduce thermal fatigue caused by frequent temperature changes in the kiln. Thermal fatigue is a phenomenon in which the internal structure is damaged due to repeated heating and cooling of materials. By reducing thermal fatigue, the service life of the equipment can also be correspondingly extended.

[0032] Secondly, when the kiln is working for a long time, the circulation pump 4 can be started, and the cold heating oil in the liquid storage tank 12 can be continuously circulated into the partition box 3. The circulation of the heating oil makes the temperature distribution of the partition layer more uniform. Compared with kilns without a partition layer or with a simple partition layer, it avoids the situation of local overheating of the middle layer. For example, in a traditional double-layer kiln, the middle layer may have uneven temperature due to heat radiation from the upper and lower layers, resulting in thermal stress concentrated in the higher temperature area. After adopting the partition layer with heating oil circulation, the thermal stress can be more evenly distributed on the entire partition layer, thereby reducing material damage caused by thermal stress concentration, such as cracks and peeling, which helps to extend the service life of the equipment.

[0033] In addition, multiple hooks 18 can be hung at the four corners of the cargo rack, the electric slide rail 19 is started, the movable plate 16 drives the rack to move to the front side of the upper kiln 2, the electric hoist 17 is started, and the rack is placed on the ground. The operator can load and unload the goods on the rack on the ground, and there is no need to move the goods onto the upper kiln 2 first, and then load or move the goods down from the upper kiln 2. Therefore, there is no need to load and unload the goods on the high floor, thereby saving a lot of manpower and material resources.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
