Description

Mesh belt furnace mouth waste heat recovery device

Technical Field

The utility model relates to a mesh belt furnace mouth waste heat recovery device, and belongs to the technical field of mesh belt furnaces.

Background

The mesh belt furnace is a heating furnace for realizing the continuous conveying of parts in the furnace through mesh belts, and is mainly used for the reduction of powder metallurgy products and metal powder and the pre-sintering, sintering or heat treatment process of electronic products in protective atmosphere or air.

The mesh belt furnace mainly comprises a furnace body, a mesh belt transmission system and a temperature control system. The furnace body consists of a feeding section, a preheating section, a heating section and a discharging section. However, when the mesh belt furnace is heated, especially at the outlet of the furnace mouth, a large amount of heat energy is emitted to the air, which causes energy waste.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: the utility model provides a mesh belt furnace fire door waste heat recovery device, it has solved when the fire door export, has had a large amount of heat energy to give off in the air, causes the extravagant problem of energy.

The technical problem to be solved by the utility model is realized by adopting the following technical scheme:

the utility model provides a guipure stove fire door waste heat recovery device, includes the casing of the type of falling U, the lateral wall fixedly connected with insulation cover of casing, the equal fixedly connected with air pump in two lateral wall bottoms of casing, two the air pump all communicates there is the pipeline, the pipeline extends to the inside of casing, the top intercommunication of casing has inlet tube and outlet pipe.

As a preferred example, the inner side wall of the shell is fixedly connected with metal fins which are uniformly distributed.

As a preferred example, the metal fin is made of copper or aluminum.

As a preferred example, the side wall of the horizontal part of the shell is fixedly connected with a heat preservation felt.

As a preferable example, the side wall of the horizontal part of the shell far away from the heat preservation felt is fixedly connected with a heat preservation curtain.

As a preferred example, the bottom of the shell is fixedly connected with a heightened walking wheel.

As a preferable example, a water suction pump is arranged on the water outlet pipe.

The utility model has the beneficial effects that: according to the utility model, through the arrangement of the shell, the shell covers the furnace mouth of the mesh belt furnace, so that heat emitted from the furnace mouth is absorbed by the medium in the shell for utilization, thereby greatly reducing the energy waste caused by the heat emitted to the air.

Drawings

FIG. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic cross-sectional structure of the present invention.

In the figure: the air pump 1, the heat preservation cover 2, the casing 3, the metal fin 4, the inlet tube 5, the outlet pipe 6, the heat preservation felt 7, the heightening walking wheel 8 and the water pump 9.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1-2, a mesh belt furnace mouth waste heat recovery device, including the casing 3 of the type of falling U, heat-conducting medium is injected into the inside of casing 3, like pure water etc., the lateral wall fixedly connected with insulation cover 2 of casing 3, the equal fixedly connected with air pump 1 in two lateral wall bottoms of casing 3, two air pumps 1 all communicate there is the pipeline, the pipeline extends to the inside of casing 3, a water for blowing in casing 3 flows, produce the torrent, the vortex, promote the hydrologic cycle, accelerate heat transmission, the top intercommunication of casing 3 has inlet tube 5 and outlet pipe 6.

The inside wall fixedly connected with evenly distributed's of casing 3 metal fin 4, metal fin 4's material is copper or aluminium, and copper and aluminium have stronger heat conductivity, and the shape design of fin makes it have great surface area simultaneously to improve the heat collection ability of furnace mouth department widely, the heat transfer that metal fin 4 collected is for the water in the casing 3.

The lateral wall fixedly connected with heat preservation felt 7 of the horizontal part of casing 3, heat preservation felt 7 uses refractory material to make, installs the back with casing 3, and heat preservation felt 7 is taken on the mesh belt furnace for casing 3 and mesh belt furnace's fire door forms relatively inclosed space, reduces the heat and gives off in the air.

The side wall of the horizontal part of the shell 3 far away from the heat preservation felt 7 is fixedly connected with a heat preservation curtain, the heat preservation curtain and the heat preservation felt 7 are made of the same material and play the same role, and the difference lies in that the heat preservation curtain is arranged to be a strand of line and vertically hung on the shell 3, so that the heat preservation curtain is prevented from obstructing the normal conveying of a mesh belt and products.

The heightening walking wheels 8 are fixedly connected to the bottom of the shell 3, so that the shell 3 can be moved conveniently, the shell 3 can be rapidly installed on or removed from the mesh belt furnace, and the subsequent transformation or maintenance and overhaul of the mesh belt furnace are facilitated.

The water outlet pipe 6 is provided with a water suction pump 9 for pumping water in the shell 3, so that the absorbed heat is convenient to use.

The working principle is as follows: when using, remove casing 3 to the fire door department of guipure stove, make casing 3 put up on the guipure, the heat that fire door department gived off is absorbed the aquatic of conduction to casing 3 in by metal fin 4, air pump 1 blows to the water in the casing 3 simultaneously, promote water and circulate, accelerate thermal exchange, it is used to store thermal water and take out by suction pump 9 and outlet pipe 6, carry out energy recycle, the water after the cooling passes through inlet tube 5 and reinjects into in the casing 3 simultaneously, absorb heat.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that various changes and modifications may be made without departing from the spirit and scope of the utility model as defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
