Abstract

The utility model discloses a reverse double-channel push plate electrical kiln, which comprises a furnace body, a furnace chamber and heating elements, wherein the furnace chamber is arranged inside the furnace body in longitudinally penetrating manner; and the heating elements are distributed inside two lateral walls of the furnace chamber. Pushing mechanisms are respectively arranged at two ends of the furnace chamber; and the two pushing mechanisms mutually and reversely push synchronously, and are provided with respective individual pushing routes. The furnace chamber is formed by two sintering channels longitudinally penetrating into the furnace body; the two sintering channels are spaced and communicated; feed inlets and discharge outlets of the sintering channels are oppositely arranged; and the pushing mechanisms are arranged at the positions of the feed inlets of the two sintering channels. Products inside the channels run reversely and synchronously, thereby waste heat portions of the products are absorbed and used by preheated products in another inlet channel beside an outlet channel after the outlet channel is fired. Temperature lowering curve is smooth, and the temperature of the products at an outlet of a furnace opening is low, thereby the reverse double-channel push plate electrical kiln realizes energy consumption recycling, reduces firing cost of the products and improves firing efficiency of the products.

Description

Electrical kiln with double backward push plates

Technical field

The utility model 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 in the utility model 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 utility model 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 utility model: the utility model 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

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a main TV structure schematic diagram of the present utility model;

Fig. 2 is a longitudinal cross-section of the present utility model schematic diagram;

Fig. 3 is a transverse sectional view of the present utility model.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model 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.
