Abstract
The invention discloses an electrical kiln with double backward push plates, comprising a furnace body, a hearth longitudinally penetrated in the furnace body and heating elements distributed in both side walls of the hearth, wherein both ends of the hearth are respectively provided with an advancing mechanism, and two advancing mechanisms mutually have backward synchronous advancements and respectively have an individual advancement line; the hearth consists of two sintering channels longitudinally penetrating the furnace body, and the two sintering channels are communicated at intervals; feed inlets and discharge outlets of the two sintering channels are oppositely arranged; and the advancing mechanisms are arranged at the feed inlets of the two sintering channels. Products in the channels are backwards synchronously moved so as to ensure that partial afterheat of products ignited of the outlet channel is absorbed and utilized by preheated products of the other inlet channel near the outlet channel. The temperature decreasing curve of the electrical kiln is smooth, and the temperature of the products at the outlet of the furnace is low so as to achieve the purposes of recycling energy consumption, reducing the firing cost of the products and improving the firing efficiency of the products.
Description
Technical field
The present invention relates to a kind of electrical kiln, especially a kind of push pedal electrical kiln that adopts the reverse synchronous operation of binary channels.
Background technology
Pushed bat kiln is industrial Thermal Equipment commonly used, particularly electrical kiln all is a key equipment in the product processing in industries such as ceramic industry, building material industry, fire-resistant industry, traditional electrical kiln adopts the single channel unidirectional operation, product pushes from the burner hearth charging aperture of electrical kiln, through preheating zone, heating region, high-temperature region, heat preservation zone and cooling area, the both sides of burning till the duct are distributed with heating tube the product in the kiln are heated, in heating, the heat of some can be absorbed by body of heater, cause thermal loss, improved energy consumption; The cooling of product is to adopt the nature cooling, therefore can emit heat, but the heat of this part well do not utilized, and the heat utilization efficiency of whole sintering procedure is reduced, and in addition, its production efficiency of electrical kiln of employing single channel structure also can't further improve.
Summary of the invention
Problem to be solved by this invention is exactly the shortcoming at prior art, a kind of electrical kiln with double backward push plates is provided, has reduced body of heater accumulation of heat, surface radiating, further improve the heat energy utilization rate, the realization energy consumption reclaims, and reduces the efficient of firing that product is fired cost, improved product.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: electrical kiln with double backward push plates, comprise body of heater, vertically run through and be arranged on the burner hearth in the body of heater and be distributed in heating element heater in the hearth biside wall, it is characterized in that: the two ends of burner hearth respectively are provided with propulsive mechanism, reverse each other synchronous implementation and have independent separately propelling route between two propulsive mechanisms.
Further, described burner hearth is made up of two passages that burn till that vertically are applied in the body of heater, article two, burn till interval UNICOM between the passage, two are provided with opposite of charging aperture of burning till passage with discharging opening, described propulsive mechanism is arranged on two charging aperture places of burning till passage.
Further, described propulsive mechanism comprises the push pedal that is used to place product, and push pedal is installed in burns till on the track set in the passage, and the charging aperture place of burning till passage is provided with propeller and acts on push pedal and slide in orbit.
Further, burn till the row's heating element heater that also alternated between the passage at two, middle heating element heater can heat simultaneously to two products that burn till in the passage, improve heat utilization efficiency, work together with the heating element heater in the hearth biside wall, only need three row's heating element heaters just can finish two heating of burning till passage, fire cost and reduce.
Further, be provided with PLC control system or host computer DCS system in the described body of heater, and undertaken artificial or control automatically by the control panel that is located at the body of heater outside.
Further, described propeller is hydraulic pusher or mechanically-propelled device.
Advantage of the present invention: the present invention is the novel energy-conserving electrical kiln that grows up on the basis of single channel push pedal electrical kiln, heating element heater three rows optimize distribution, with compare with two single holes of output, reduced body of heater accumulation of heat, surface radiating, further improved the utilization rate of heat energy; The reverse synchronous operation of product in the passage, product waste heat part is absorbed by the pre-hot product of its another access road of next door after making the exit passageway calcination, and temperature lowering curve is level and smooth, and fire door exported product temperature is low, thereby realize the energy consumption recycling, reduce the efficient of firing that product is fired cost, improved product.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is a main TV structure schematic diagram of the present invention;
Fig. 2 is a longitudinal cross-section of the present invention schematic diagram;
Fig. 3 is a transverse sectional view of the present invention.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the present invention is an electrical kiln with double backward push plates, comprise body of heater 1, vertically run through and be arranged on the burner hearth in the body of heater 1 and be distributed in heating element heater 4 in the hearth biside wall, the two ends of burner hearth respectively are provided with propulsive mechanism, reverse each other synchronous implementation and have independent separately propelling route between two propulsive mechanisms.Burner hearth can be arranged to two and vertically run through and burn till 2, two in passage and burn till 2 in passage and connect mutually, two are provided with opposite of charging aperture of burning till passage 2 with discharging opening, and described propulsive mechanism is arranged on two charging aperture places of burning till passage 2.Propulsive mechanism comprises the push pedal 31 that is used to place product, push pedal 31 is installed in burns till on the track 12 set in the passage 2, the charging aperture place of burning till passage 2 is provided with propeller and acts on push pedal 31 and slide in track 12, and propeller 3 can adopt hydraulic pusher or mechanically-propelled device.Burn till the row's heating element heater 4 that also alternated between the passage 2 at two, middle heating element heater 4 can heat simultaneously to two products that burn till in the passage 2, improve heat utilization efficiency, work together with the heating element heater 4 in the hearth biside wall, only need three row's heating element heaters 4 just can finish two heating of burning till passage 2, fire cost and reduce.Above-mentioned heating element heater 4 can adopt resistance wire, Elema or Si-Mo rod, is provided with PLC control system or host computer DCS system in the electrical kiln body of heater 1, and is undertaken artificial or control automatically by the control panel 11 that is located at body of heater 1 outside.The reverse synchronous operation of product in the passage, product waste heat part is absorbed by the pre-hot product of its another access road of next door after making the exit passageway calcination, and temperature lowering curve is level and smooth, and fire door exported product temperature is low, thereby realize the energy consumption recycling, reduce the efficient of firing that product is fired cost, improved product.
