Abstract

The utility model relates to kiln type heating equipment, in particular to tunnel type heating equipment. The tunnel type heating equipment comprises a furnace body. The furnace body comprises a furnace top, furnace walls on the two sides of the furnace top, and a furnace bottom. A long tubular heating chamber is formed by the furnace top, the furnace walls and the furnace bottom. A track is arranged at the furnace bottom and provided with a plurality of trolleys. The trolleys are loaded with processed products and operate in the heating chamber along the track. The middle of each trolley is provided with a heat baffle perpendicular to the length direction of the furnace body. The heat baffles are arranged vertically, and the top edge of each heat baffle is close to the furnace top. The movable heat baffles are arranged in the heating chamber at intervals, hot air at the upper portion of the furnace body is stopped from directly and rapidly flowing forwards and being exhausted, heat is made to be gathered in the heating chamber to pass through the space between the lower edge of a heating board and each trolley, and the utilization rate of heat is increased by at least one time. The distribution situation of heat of the cross section, perpendicular to the length direction of the furnace body, of the furnace body is improved, heat can be evenly distributed, the temperature difference is small, the processed products are evenly heated, and the quality is improved.

Description

A kind of tunnel type firing equipment

Technical field

The utility model relates to kiln type firing equipment, and tunnel type firing equipment espespecially for curing, sintering etc., is having good promotional value aspect the Industrial Stoves such as building materials, pottery.

Background technology

Tunnel type kiln is had many uses as a kind of industrial kiln.Body of heater is straight-tube shape, has the elementary cells such as charging aperture, the thermal treatment zone, vehicle outlet, conveying device and heating system, mainly take combustion gas or coal as fuel.Tunnel type kiln is the equipment that a kind of energy consumption is high, and temperature difference height big or small and energy utilization rate upper and lower in kiln is the leading indicator of weighing tunnel type furnace performance.Furnace construction is one of principal element affecting tunnel type kiln energy consumption level.The structure of the tunnel type kiln of prior art has following deficiency at least:

One, Fig. 1 is the tunnel cave schematic diagram of a kind of baking red bricks of prior art.Generally, thermal current floats toward upper of furnace body because the high volume of temperature increases light specific gravity, and the front end from the thermal treatment zone after thermal current floating flows toward flue, and most of heat is directly taken away from flue, causes heat-energy losses large, and efficiency is low.

Its two, on the body of heater cross section vertical with body of heater length direction, heat skewness weighing apparatus, the temperature difference is large.The situation of Fig. 1, upper height bends down, and upper and lower temperature difference is very large.And product to be processed is all positioned at middle part and the bottom of body of heater.On the one hand, energy consumption is improved, because whether in body of heater, the processing of product generally be take to each position of product all burned for indicating, if the part in low temperature position is burned with regard to kiln discharge, belong to defective work, certainly will be increased in firing time in body of heater like this, energy consumption improves.Another aspect, causes adverse effect to the quality of product to be processed, and each position of product is heated irregular, easily causes distortion, wrinkling, cracking etc., or loads the adobe heating of pile on dolly and differ, and the burning on top has been crossed, bottom go back underburnt.

Summary of the invention

The utility model technical issues that need to address are that the tunnel type kiln thermal current that overcomes prior art floats to upper of furnace body in a large number, only heated the product on top just from just directly draining from flue, thereby cause heat-energy losses large, the deficiency that body of heater efficiency is low, and heat skewness weighing apparatus on the body of heater cross section vertical with body of heater length direction, upper heat and lower cold, cause having a strong impact on product to be processed quality, now, a kind of tunnel type firing equipment is provided, the thermal current that this tunnel type firing equipment can stop upper of furnace body is rapid flow forward straight, changed thermal current flow direction, can greatly improve energy and utilize effect, reduce energy consumption, improve product to be processed quality.

For this reason, a kind of tunnel type firing equipment of the utility model adopts following technical proposals:

A tunnel type firing equipment, comprises body of heater, and described body of heater comprises furnace roof, is positioned at furnace wall and the furnace bottom of furnace roof both sides, and furnace roof, furnace wall and furnace bottom form the heating clamber of long tubular; At furnace bottom, track is set, track is laid along body of heater length direction, multi-section is installed in orbit and is loaded the dolly of product to be processed and move in heating clamber along track; In heating clamber, also interval arranges the mobile hot baffle vertical with body of heater length direction, and the vertical setting of described hot baffle and its top edge and furnace roof are close; Described hot baffle is arranged on described in each on dolly, and the bottom of described hot baffle arranges supporting leg, and supporting leg is placed on described dolly, between the lower limb of described hot baffle and the loading surface of dolly, leaves space, usings the passage flowing through as thermal current.

Hot baffle is made of exotic material.

Compared with the existing technology, the beneficial effects of the utility model are:

One, in heating clamber, interval arranges mobile hot baffle, the thermal current that stops upper of furnace body straight forward rapid flow discharge out of the furnace, changed the consistent flow direction forward of thermal current, when the thermal current on top is being met hot baffle, by hot baffle, blocked, thermal current down passes; Then thermal current floating forward, form and---thermal circulation along vertical plane that move ahead---floating---moves ahead, heat is assembled at heating clamber, substantially in heating clamber, heats product to be processed always, the heat running off greatly reduces, and the utilization rate of heat is enhanced about more than once.

Its two, solved the problem that arranges of hot baffle, because hot baffle can not be installed on furnace roof, if be arranged on furnace roof, the distance that hot baffle is stretched downwards certainly will be very short, to stopping that thermal current does not play much effects, if the distance of stretching is downwards large, will obstacle dolly current.

They are three years old, due to the thermal circulation effect along vertical plane, improved heat distribution situation on the body of heater cross section vertical with body of heater length direction, it is evenly distributed, has a narrow range of temperature, product to be processed is heated evenly, thereby promote the raising of product to be processed quality, reduce distortion, wrinkling, cracking etc., load the adobe of pile on dolly and there will not be the burning on top to cross, and bottom does not also have a burned phenomenon.

Its four, the technical program is simple, is convenient to promote.Its economic benefit (cost-saving) and social benefit (the saving energy) are very outstanding.
