Abstract
The utility model relates to the technical field of oven heating, in particular to a hot air heating device of an oven. The hot air heating device of the oven comprises a combustion chamber, wherein the combustion chamber is provided with a fresh air inlet, a return air inlet and an air outlet. The hot air heating device of the oven is characterized in that a flame protection drum is arranged in the combustion chamber, a flame burns in the flame protection drum to release heat, one end of the flame protection drum is connected with the fresh air inlet, the other end of the flame protection drum is provided with a flame baffle wall which prevents the tail end of the flame from being ejected out of the flame protection drum, namely an isolation heating structure is formed, and then hot air does not need to touch the naked flame. According to the hot air heating device of the oven, the isolation heating structure is adopted; due to the facts that the naked flame in the combustion chamber is surrounded by the flame protection drum and the flame baffle wall is arranged at the front end of the flame, the naked flame is prevented from heating the air directly, and full and uniform heating is realized; due to the fact that a filter is arranged, the requirement for air cleanliness is met; due to the fact that a high-temperature thermocouple is arranged in the hot air heating device, the temperature of the hot air can be controlled accurately, and the requirement of a product for air temperature is met; as a result, the hot air heating device has the technical advantages of being safe, stable, clean and capable of saving energy.
Description
[technical field]
The utility model relates to baking oven technical field of heating, specifically a kind of baking oven Hot-blast Heating equipment.
[background technology]
In baking oven Hot-blast Heating equipment utilization air and baking oven, waste heat gas fully mixes the principle that reaches temperature and dries product, general baking oven Hot-blast Heating equipment is made up of a hot-blast heater and two blower fans and two air doors, wherein two blower fans can carry out periodic air feed and air draft, and the gas after heating by hot-blast heater enters baking oven through air feed blower fan and dries product.
Because the hot gas of drying product can not directly contact naked light, temperature accuracy is had relatively high expectations, and needs certain cleanliness factor, so common stove heating hot blast does not reach the hot blast of high-precision temperature requirement all the time.
[summary of the invention]
The purpose of this utility model is exactly that will to solve above-mentioned Hot-blast Heating temperature precisely not enough and a kind of new structure Hot-blast Heating equipment is provided, and hot gas is without contact naked light, the Hot-blast Heating equipment that temperature is accurate and clean.
For achieving the above object, design a kind of baking oven Hot-blast Heating equipment, comprise combustion chamber, described combustion chamber is provided with fresh wind port, return air inlet and air outlet, it is characterized in that being provided with and protecting fire cylinder in described combustion chamber, flame is in protecting fiery cylinder roasting heat release, described one end of protecting fire cylinder is connected with fresh wind port, described in protect fire cylinder the other end be provided with firebreak, block the ejection of flame end and protect fire tin, form isolation heating arrangement, realize hot gas without contact naked light.
Atmosphere enters combustion chamber by fresh wind port, described in protect fire cylinder and be provided with square shaped teeth breach with one end end face being connected with fresh wind port, new wind increases oxygen by this square shaped teeth breach to burner, realizes fully burning; Described protecting between the fire cylinder other end and firebreak is provided with spacing, ensures to protect the certain circulation of fire cylinder inner air and outer air.
Protect fire cylinder cylindrical shell surrounding for new wind is hovered above, full and uniform heat absorption is provided with flow-stopping plate on the barrel that protects fire cylinder cylindrical shell surrounding.
In described Hot-blast Heating equipment, be also provided with pyrometer couple, precisely control hot blast temperature.
Consider and need the outwards clean hot blast of output, be therefore provided with filter, Purge gas at air outlet place, combustion chamber.
The utility model compared with the existing technology, has adopted isolation heating arrangement, and due to naked light surrounding in combustion chamber is surrounded with protecting fire cylinder, flame front is provided with firebreak, thereby has solved the direct heated air of naked light, and the full and uniform heating of energy; Owing to being provided with filter, thereby solve the requirement of cleaning gas degree; Due to the interior pyrometer couple that is provided with, precisely control hot blast temperature, solve product to gas temperature requirement, thereby reached safety, stable, clean, energy-conservation technique effect.
[brief description of the drawings]
Fig. 1 is structural principle schematic diagram of the present utility model;
In figure: 1. fresh wind port; 2. combustion chamber; 3. deflection plate; 4. protect fire cylinder; 5. firebreak; 6. return air inlet; 7. air outlet; 8. filter.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, the structure of this device is very clearly concerning this professional people.
This cover energy-saving type baking oven Hot-blast Heating equipment, as shown in Figure 1, comprise combustion chamber 2, protect fire cylinder 4, firebreak 5, deflection plate 3, fresh wind port 1, return air inlet 6, filter 8, wherein, combustion chamber 2 is positioned at the upper portion of Hot-blast Heating equipment, and the lower portion of Hot-blast Heating equipment is for installing purifier and getting rid of clean hot blast.
The first, the isolation heating arrangement of install combustion chamber 2, this nested structure forms by protecting fire cylinder 4, firebreak 5, deflection plate 3, and wherein one end of protecting fire cylinder 4 has square shaped teeth breach, and the other end adopts burnishing surface, and is protecting fire cylinder 4 cylindrical shell surroundings stack assembling flow-stopping plates 3.First, fresh wind port 1 is installed by import department in combustion chamber 2, then in combustion chamber 2 interior by fresh wind port 1 with protect fire tins 4 and have one end end face of square shaped teeth breach to be connected, then at the position mounting block wall with flues 5 keeping at a certain distance away with the other end that protects fire cylinder 4, and return air inlet 6 is arranged on combustion chamber 2 walls at firebreak 5 back sides.Atmosphere enters combustion chamber 2 by fresh wind port 1, and because wherein one end of protecting fire cylinder 4 is provided with square shaped teeth breach, new wind increases oxygen by square shaped teeth breach to burner, can fully burn; Be provided with flow-stopping plate 3 owing to protecting fire cylinder 4 cylindrical shell surroundings again, new wind can hover above and protect fire cylinder surrounding, full and uniform heat absorption.
The second, purifier is installed.This cover purifier is filter 8, is arranged on the lower portion of Hot-blast Heating equipment, the below of combustion chamber; Hot blast warp after filter 8 purifies is discharged by air outlet 7.
The 3rd, accurate temperature regulating device can also be installed.This accurate temperature regulating device can be selected pyrometer couple, is installed in Hot-blast Heating equipment, for precisely controlling hot blast temperature.
