DETAILED DESCRIPTION

[0031] The following description will be made in conjunction with the accompanying drawings Figures 1-3 The application is further described in detail.

[0032] The application discloses a ceramic wet body drying device. Referring to Figure 1 and Figure 2 The drying device comprises a drying chamber 1, a waste heat pipeline 2 and a dust removal assembly 3. One end of the waste heat pipeline 2 is communicated with a kiln, and the other end is communicated with the drying chamber 1 and provides heat for the drying chamber 1.

[0033] The outer side of the drying chamber 1 is sleeved with a heat preservation chamber 4, which is made of a heat preservation material. The inner bottom wall of the heat preservation chamber 4 is fixedly connected with the outer bottom wall of the drying chamber 1, and one side wall of the drying chamber 1 is hingedly connected with a door body 11. The outer side wall of the drying chamber 1, which is provided with the door body 11, is also fixedly connected with the corresponding inner side wall of the heat preservation chamber 4.

[0034] A heat preservation cavity is arranged between the drying chamber 1 and the heat preservation chamber 4, and a plurality of air inlet holes are formed in the opposite two side walls of the drying chamber 1. The waste heat pipeline 2 comprises a main pipeline 21 communicated with the kiln, and further comprises two branch pipelines 22 fixedly connected with the main pipeline 21. One end of each branch pipeline 22, which is away from the main pipeline 21, is fixedly connected with one side wall of the drying chamber 1, and each branch pipeline 22 is communicated with the heat preservation chamber 4.

[0035] The waste heat generated by the kiln enters the heat preservation chamber 4 along the main pipeline 21 and the branch pipelines 22, and then enters the drying chamber 1 through each air inlet hole, so as to dry the ceramic wet body in the drying chamber 1.

[0036] Referring to Figure 2 and Figure 3 The dust removal assembly 3 is installed on the main pipeline and used for filtering dust. The dust removal assembly 3 comprises a dust removal box 31 communicated with and fixedly connected to the main pipeline, and the dust removal box 31 is fixedly connected to one side wall of the heat preservation chamber 4. One side surface of the dust removal box 31 is provided with a connecting port 311, and a filter drawer 32 is slidably connected in the connecting port 311. The bottom surface of the filter drawer 32 is provided with a filter screen 321.

[0037] The dust passing through the main pipeline enters the dust removal box 31, and then is filtered through the filter screen 321 and collected in the filter drawer 32. When it is needed to clean the dust in the filter drawer 32, the filter drawer 32 can be conveniently pulled out of the dust removal box 31, and the filter screen 321 can effectively intercept the dust, so that the dust entering the drying chamber 1 is reduced. The effect of effectively filtering the dust and conveniently cleaning and maintaining is achieved.

[0038] Tracks 312 are formed in the two inner side walls of the dust removal box 31, and rollers 33 are rotatably connected to the two outer side walls of the filter drawer 32. Each roller 33 is in rolling cooperation with the corresponding track 312.

[0039] A side wall of the filtering drawer 32 is provided with a sealing plate 322 for sealing the connecting port 311, and the filtering drawer 32 is gradually inclined downward in a direction away from the sealing plate 322, and each rail 312 is also inclined, and the inclination direction of the rail 312 is consistent with that of the filtering drawer 32. This design helps the dust to automatically slide to the bottom area of the filtering drawer 32, and reduces the accumulation of dust on the filter screen 321 to affect the filtering effect.

[0040] The implementation principle of the ceramic wet body drying device is that the dust box 31 and the filtering drawer 32 are arranged on the waste heat pipeline 2 to effectively filter the dust in the kiln waste heat, and reduce the situation that the dust enters the drying chamber 1 to affect the wet body drying quality. The sliding plug-in design of the filtering drawer 32 makes the filtering drawer 32 easy to clean and replace, and improves the maintenance convenience of the equipment. The design of the heat preservation chamber 4 and the heat preservation cavity further improves the heat energy utilization rate, reduces the energy loss, and achieves the energy saving and emission reduction target.

[0041] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
