Abstract

The utility model relates to a high-efficient microwave road surface heater including a shell, a bracket, many magnetrons, a transformer, a refrigerating device, a unit cavity, a microwave leakage protector, an electrical distribution box and a control electrical box. The refrigerating device is equipped corresponding to the magnetron and the transformer. The connection of all the unit waveguide cavities guarantees that the microwave produced by the magnetron does not leak outwards. The magnetron which is equipped on the unit cavity is respectively equipped on the upper end of each unit waveguide cavity. The magnetron entirety is stairs-shaped arranged. The microwave leakage protector is surrounding equipped at lower end of the entire unit waveguide cavity. The high-efficient microwave road surface heater can be equipped with more magnetrons than the prior art in the unit plane area, which causes the heating time short and causes the efficiency high. The magnetron is stairs-shaped arranged and is mutually staggered simultaneously. The mutual interference between the magnetrons is small and the service life of the magnetron is long.

Description

The efficient microwave road heater

1. technical field

The utility model belongs to a kind of road surface and repairs machinery, particularly a kind of microwave road heater that is used for the flexible pavement maintenance.

2. background technology

At present, road surfaces such as the speedway that constitutes for bituminous concrete, urban road because of ageing of asphalt or flexible pavement are subjected to improper rolling, cause road surface crackle, local distortion, pit, bulge etc. to cause the highway pavement out-of-flatness.Repair problem in order to solve the road surface, people have designed some heating using microwave prosthetic devices now, as Chinese patent " asphalt pavement conserving maintenance heater, 99253511 " is exactly to utilize microwave heating principle, reaches the purpose on maintenance road surface with a plurality of high power magnetron road pavement heating.The heating of this technical scheme road pavement have energy consumption low, pollute little, low cost and other advantages, but, because all magnetrons are arranged in the same horizontal plane, therefore, magnetron negligible amounts in the unit area, when road pavement heated like this, the road surface of unit area received microwave amount in the unit interval was less, heat time heating time is longer, and operating efficiency is not high; And the quantity of increase magnetron, must increase the area of whole heater, magnetron quantity in the unit area is not increased, it is more simultaneously magnetron quantity to be set in same plane, can make the phase mutual interference between the different magnetrons bigger, shorten the application life of magnetron, so the application of this technical scheme is subjected to bigger restriction.

3. summary of the invention

The purpose of this utility model is to provide a kind of can three-dimensionally heat bituminous concrete in flexible pavement is repaired, guarantee that the bituminous concrete temperature rise is even, and heat time heating time is short, the efficient microwave road heater that efficient is high.

The utility model is to realize like this, it includes shell, support, a plurality of magnetron, transformer, cooling unit, unit wave-guide cavity wave, and microwave leakage protector, switchbox, control electronic box, corresponding magnetron of cooling unit and transformer setting, all unit wave-guide cavity waves are to be tightly connected, the microwave that guarantees the magnetron generation is not to external leakage, the magnetron of installing on the unit cavity is separately positioned on the upper end of each unit wave-guide cavity wave, the stepped arrangement of the whole one-tenth of magnetron, the microwave leakage protector is around in whole unit wave-guide cavity wave lower end.

Each unit wave-guide cavity wave of the present utility model is tightly connected by the transition waceguide of the standard waveguide joint on top and bottom and forms, like this, can be as the case may be, realize the purpose of adjustment unit wave-guide cavity wave height by the height of adjusting standard waveguide joint or transition waceguide, very convenient.

Good effect of the present utility model is: because magnetron is separately positioned on the upper end of each unit wave-guide cavity wave, the stepped arrangement of its whole one-tenth, magnetron has staggered mutually, therefore can be provided with than the more magnetron of prior art according to concrete needs in the unit area of plane, can three-dimensionally heat bituminous concrete in flexible pavement is repaired, guarantee that the bituminous concrete temperature rise is even, the road surface of unit area can receive more microwave in the unit interval, cause heat time heating time short, the efficient height; Magnetron becomes stepped arrangement to stagger mutually simultaneously, can guarantee that the hidden danger that interferes with each other between magnetron and the magnetron reduces to minimum, guarantees the application life of magnetron.

4. description of drawings

Accompanying drawing 1 only keeps the structural representation of magnetron, unit cavity and microwave leakage protector for the utility model removes miscellaneous part;

Accompanying drawing 2 is the right view of accompanying drawing 1.

5. the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

As shown in drawings, the utility model includes shell, support, a plurality of magnetron 1, transformer, cooling unit, unit wave-guide cavity wave, and microwave leakage protector 4, temperature inductor, switchbox, control electronic box, the side of support is provided with the hanger that is connected with jacking equipments such as power fork trucks, and the bottom of support is provided with adjustable support leg; Corresponding magnetron 1 of cooling unit and transformer setting, each unit wave-guide cavity wave is tightly connected by the transition waceguide 3 of the standard waveguide joint 2 on top and bottom and forms, standard waveguide joint 2 is provided with the magnetron mounting bracket, the area of the height of standard waveguide joint 2 and transition waceguide 3 and transition waceguide 3 lower ending openings can freely be adjusted according to design, be tightly connected between all transition waceguide 3 lower ending openings, all unit wave-guide cavity waves are divided into some different height and the upper end becomes stepped arrangement, magnetron 1 is separately positioned on the magnetron mounting bracket of standard waveguide joint 2 of each unit wave-guide cavity wave, the same stepped arrangement of whole one-tenth, the quantity of magnetron 1 is according to the thermal efficiency of magnetron heating bituminous concrete, heat time heating time, actual conditions settings such as heating bituminous concrete volume, microwave leakage protector 4 is around in the lower end of whole transition waceguide 3, plays good anti-microwave leakage function.

When the utility model uses, utilizing jacking equipment such as fork truck that the utility model is moved to the position, road surface that needs to repair puts down, adjust the adjustable support leg of support bottom, follow power-on, magnetron 1 work, the microwave that is produced is delivered to the road surface through each unit wave-guide cavity wave transition waceguide 3 lower ending opening bituminous concrete is heated, when being heated to when temperature required, the utility model is removed, can be repaired this part road surface.The utility model can carry out solid to bituminous concrete heats, and guarantees that the bituminous concrete temperature rise is even, avoids producing that pitch burns and denaturalization phenomenon; Use the magnetron of the stepped arrangement of a plurality of one-tenth to heat, shortened heat time heating time, high efficiency, interfering with each other between magnetron and the magnetron is little, the long service life of magnetron.
