Abstract
The utility model relates to the heat insulation door curtain of a kind of electromagnetic shielding, comprise cover plate, installed on the cover board and the connecting rod baffle plate that can rotate around bearing pin, be arranged on the door curtain on connecting rod baffle plate by clamping fixture by bearing pin, door curtain is multi-layer intercrossed or parallel array formula and arranges on the cover board; The beneficial effects of the utility model are that hot environment and electromagnetic district are effectively isolated, and this apparatus structure is simple, easy to install.
Description
Technical field
The utility model belongs to the technical field of preventing electromagnetic leakage, relates in particular to a kind of electromagnetic heat-insulating door curtain in microwave applications field.
Background technology
At traditional tunnel type micro wave kiln entrance end, due to the motion of conveyer belt, there is electromagnetic sealing problem, electromagnetic shielding mode is one of bottleneck all the time.Tunnel type micro wave kiln material is is dynamically imported and exported shielding construction at present two kinds, and one is, at opening part, baffle plate gate is set, and material enters cavity and opens baffle plate, and the intermittent baffle plate that closes can not leak microwave; This mode is simple in structure, but needs automatically to control, and cost is higher.The second way is in open height hour, suppresses the method for harmonic wave with chokes, make microwave not to external leakage, but limitation is large, is not suitable for the occasion of air seal.
In Chinese patent literature, publication number is that CN203325480U, name are called screening machine luggage and disclose a kind of scheme (particular content referring to description in full) by reducing the document of device of radiation leakage amount in process, be included in the first shielding curtain in cabinet porch and exit, inner side or outside at the first shielding curtain are provided with the secondary shielding curtain being connected with cabinet, and secondary shielding curtain extends to conveyer belt surface, between two shielding curtains, form a confined space, two shielding curtains are alternately opened, shielding curtain is provided with hanging hole, is hung on cabinet top board.
Technique scheme, by the alpha ray shield in cabinet, has reduced leaking of cabinet inner rays.But in such scheme, confined space of the pattern of wants between two shielding curtains, by alternately opening and realize pre-ray-proof leakage, and in continuous microwave cracking, dynamically input continuously of material, cannot form above-mentioned confined space.The mounting means complexity of such scheme is loaded down with trivial details, has improved production cost, is difficult for realizing in microwave cracking device.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of electromagnetic heat-insulating door curtain, and object is to realize preventing that microwave from leaking and high temperature insulating, and this apparatus structure is simple, easy to install.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is the heat insulation door curtain of a kind of electromagnetic shielding, comprise cover plate, install on the cover board and the connecting rod baffle plate that can rotate around bearing pin, be arranged on the door curtain on connecting rod baffle plate by clamping fixture by bearing pin, door curtain is multilayer arranges on the cover board, and layer is to interlock or parallel arrangement mode with the door curtain of interlayer.
Compared to the prior art, the carrier of this programme using cover plate as door curtain, has on the cover board realized the modularization of door curtain by door curtain by connecting rod baffle plate and bearing pin etc. are fixing, only needs cover plate to be placed on corresponding position when installation; Meanwhile, this programme has adopted and has been the multi-layer intercrossed or parallel door curtain arrangement of arranging of array, and in material conveying process, door curtain drivening rod baffle plate rotates alternately folding, the high-intensity electromagnetic wave leaking that intercepted around bearing pin.
Based on such scheme, the utility model has also done following improvement:
Described cover plate, connecting rod baffle plate, door curtain surface all scribble high temperature resistant wave-permeable heat insulating coat; In this improvement project, door curtain assembly surface is equipped with high temperature resistant wave-permeable heat insulating coat, and hot environment and electromagnetic district are effectively isolated, and has further stoped leaking of microwave and high temperature.
Connecting rod baffle plate and cover plate are provided with the hollow cylinder cooperatively interacting, and bearing pin runs through hollow cylinder successively to be fixed connecting rod baffle plate on the cover board; In this improvement project, connecting rod baffle plate and cover plate are provided with hollow cylinder, by bearing pin, the two are connected, and this mode that is connected and fixed is simple and easy to install.
Clamping fixture comprises for door curtain being pressed on to pressing plate and the bolt and nut on connecting rod baffle plate; In this improvement project, because door curtain is thinner, be directly fixed on connecting rod baffle plate fragilely by bolt etc., service life is short, in order to improve fixed effect, increases service life, and this programme compresses door curtain by pressing plate and bolt.

In figure, 1. cover plate; 2. bearing pin; 3. pressing plate; 4. connecting rod baffle plate; 5. door curtain.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is elaborated.
Embodiment
As shown in Figure 1, 2, a kind of electromagnetic heat-insulating door curtain of the utility model comprises cover plate 1, is arranged on cover plate 1 and the connecting rod baffle plate 4 that can rotate around bearing pin 2, is arranged on the door curtain 5 on connecting rod baffle plate 4 by pressing plate 3 and bolt and nut by bearing pin 2; Connecting rod baffle plate 4 and cover plate 1 are provided with the hollow cylinder cooperatively interacting, and bearing pin 2 runs through successively hollow cylinder connecting rod baffle plate 4 is fixed on cover plate 1; Connecting rod baffle plate 4 rotates around bearing pin 2 under the drive of door curtain, and connecting rod baffle plate 4, at bearing pin 2 axial directions, significantly displacement can not occur, and has ensured air-tightness; Connecting rod baffle plate 4 is not limited to aforesaid way with the connected mode of cover plate 1, can, according to actual installation needs, realize its function.
As shown in Figure 3,4, door curtain 5 is multi-layer intercrossed or parallel array formula and is arranged on cover plate 1, and door curtain 5 multi-layer array types are arranged non-high temperature, the non-electromagnetism region of needing effectively protected.
Cover plate 1, connecting rod baffle plate 4, door curtain 5 are metal material, and surface scribbles high temperature resistant wave-permeable heat insulating coat; The durability of metal material is better, and cost is low.
