Description

Technical Field

[0001] The invention belongs to the technical field of drying box equipment, and in particular relates to an air outlet structure of a drying box. Background Art

[0002] The electric blast drying oven uses the heat generated by the heated air blown by the blower to ensure the temperature balance in the oven, and can be used to bake, dry, solidify, heat treat and perform other heating treatments on various materials. In the case where there is a lot of dust in the material, the exhaust port will bring out a lot of dust when the drying oven is working. The accumulation of dust will affect the normal ventilation of the pipeline, and the exhausted gas will also cause air pollution. In the prior art, although there is a form of filtering by setting a filter at the air outlet, for materials with a lot of dust, a large amount of dust can easily clog the filter during the electric blast drying process. Therefore, it is necessary to improve the filtering structure at the air outlet of the existing drying oven. Summary of the invention

[0006] Furthermore, the fixed end, the box body, and the pipe connecting end are an integrally formed structure.

[0007] Furthermore, the end cap includes a bottom plate and a side plate outside the bottom plate, and the side plate is fixed to the outer wall of the cleaning port by a connecting piece.

[0008] Furthermore, the connecting piece is a screw.

[0009] Furthermore, the filter screen is made of a stainless steel filter screen.

[0010] Furthermore, three baffle plates are continuously provided on the side close to the fixed end.

[0011] Furthermore, the pipeline connecting end is in a cylindrical structure, and a plurality of convex rings are provided on its outer wall.

[0012] Furthermore, the mesh diameter of each filter screen decreases in sequence from the fixed end side to the pipeline connection end side.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The invention has a reasonable structural design.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] A drying box air outlet structure, such as Figures 1 to 6 As shown, it includes a dust box 2 installed on the side plate 1 of the drying box, and the dust box includes a box body 3. A fixed end 4 is provided on one side of the box body, and a pipe connection end 5 is provided on the other side. Usually, the fixed end, the box body, and the pipe connection end are an integrated structure. The opening of the fixed end corresponds to the air outlet 6 of the drying box on the side plate, and the pipe connection end is open. A plurality of filter screens 7 are provided in the box body, and at least one baffle plate 8 is provided on the side of each filter screen close to the fixed end. The mesh diameter of each filter screen decreases from the fixed end side to the pipe connection end side.

[0027] The baffle plate is provided with a plurality of through holes 9, and a retaining eave 10 is provided corresponding to each through hole on the side of the baffle plate facing the pipeline connection end, and the through holes on two adjacent baffle plates are staggered; the retaining eave is arranged obliquely downward, and its upper edge is above the corresponding through hole; a cleaning port 11 is provided at the lower end of the box body, and an end cap 12 is detachably mounted on the cleaning port, and a sealing member 13 for forming a seal with the upper surface of the end cap is provided at the lower end of the cleaning port. In an optional embodiment, the pipeline connection end is a cylindrical structure, and a plurality of outward convex rings are provided on its outer wall. When connected to the ventilation pipeline, the ventilation pipeline can be fitted on the pipeline connection end and fixed with a throat clamp, and the sealing performance is good.

[0028] The end cap includes a bottom plate 14 and a side plate 15 on the periphery of the bottom plate. The side plate is fixed to the outer wall of the cleaning port by a connector 16. The side plate is enclosed on the outside of the bottom plate, so that the end cap forms a concave cavity 16. As an example, the connector is a screw. The filter screen is a stainless steel filter screen. On the side close to the fixed end, three baffles are continuously arranged. The dust in the air is blocked by multiple baffles, so that the dust collides with the baffles, and part of the dust will fall to the bottom of the dust box along the baffles. When the airflow containing dust passes through the hole and is discharged to the pipeline connection end, it will also be blocked by the eaves, so that part of the dust falls to the bottom of the dust box. Therefore, after the blocking effect of the multiple baffles, the amount of dust contacting the filter screen is reduced, reducing the burden of the filter screen, and the mesh size of each filter screen is increased from the fixed end to the pipeline connection end, forming a (coarse filtration, fine filtration) multi-stage filtration effect.

[0029] The invention has a reasonable structural design. By installing a dust collecting box at the air outlet of the drying box, the gas with a large dust content discharged from the drying box can be filtered through the multi-stage filtering effect of the multi-layer baffle plates and the filter screen, so that the dust can be effectively filtered. The filter screen has good durability and is not easy to be blocked. It only needs to remove the lower end cap regularly to dump the dust accumulated at the bottom of the dust collecting box. The operation is convenient and the use effect is good.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
