Problems solved by technology

[0006] Compared with the prior art, the beneficial effect of the present invention is that: the present invention solves the problem that the shaft furnace cannot discharge material horizontally, and the discharge device provided has a simple structure, works intermittently, is convenient for equipment maintenance, does not affect the operating rate, and especially does not require continuous Working at high temperature solves the problem of high-temperature material discharge in existing shaft furnaces. High-temperature discharge not only shortens production time, improves productivity, but also saves energy consumption for further melting of materials

Embodiment 1

[0034] The supporting part adopts a hollow sleeve structure, and the discharge part is composed of a push plate and a push rod. The front end of the hollow sleeve is provided with convex teeth, and the tail end of the hollow sleeve is connected with the driving device; the inner cavity of the hollow sleeve slides with the push plate Cooperating, the pushing plate is flexibly connected with one end of the push rod, and the other end of the push rod is connected with the driving device.

[0035] The length of the hollow sleeve is not less than the distance between the two outlets of the reaction chamber, and the dimension of the longitudinal section of the hollow sleeve along the length direction is smaller than the size of the outlets. The hollow sleeve can adopt any cylindrical structure such as cylinder, square cylinder, inverted U-shaped cylinder, triangular cylinder and diamond-shaped cylinder, which can enter through the material layer from the discharge port at one end to ...

Embodiment 2

[0041] see Figure 9 to Figure 13 , when the support member adopts the support plate 14 structure, the shaft furnace reinforced furnace wall is provided with a horizontal boss along the direction of the discharge channel, and the boss is lower than the upper edge of the discharge port. The discharge member is composed of a second pusher plate 16 and a second push rod 17 and the like. The front end of the support plate 15 is provided with an inclined surface 18, the rear end of the support plate 14 is fixedly connected with the front end of the push plate 19, the upper plane of the push plate 19 is equipped with a double-sided rack 20, and the double-sided rack 20 is used to cooperate with the hydraulic motor 21. The lower part of the support plate 14 and the push plate 19 is slidably connected with the second positioning slideway 22, and the second positioning slideway 22 is fixed on the second frame body 24 through the first supporting device 23; the push plate 19 passes thro...

Abstract

The invention discloses a discharging device of a shaft furnace, and relates to the technical field of discharging devices. The discharging device of the shaft furnace comprises a supporting piece, adischarging piece and a driving device; one end of the supporting piece and one end of the discharging piece are connected with the driving device correspondingly, and the interior or the bottom of the supporting piece is in sliding fit with the discharging piece; and the length of the supporting piece is not smaller than the distance between two discharging openings in the shaft furnace. The discharging device is simple in structure and works intermittently, so that equipment maintenance is facilitated, and the operation rate is not affected; and the discharging device particularly does not need to work continuously at high temperature, so that the problem of discharging of high-temperature materials is solved, through high-temperature discharging, the production time is shortened, the production rate is improved, and energy consumption is saved for further melting and separating of the materials.

Description

technical field [0001] The invention relates to the technical field of discharge devices, in particular to a discharge device for a shaft furnace. Background technique [0002] The discharge system of the existing shaft furnace all adopts the bottom discharge method, and the existing deficiencies are mainly reflected in: (1) a single reaction chamber needs multiple discharge systems, the equipment is complicated, there are many faults, the productivity is low, and the equipment investment is large; (2) ) uses a discharge valve structure, which is not suitable for thermal discharge. The discharge valve works continuously in a high temperature environment, resulting in large losses, short life, low operating rate, and cannot be maintained; [0003] The publication number is CN208104453U, a discharge system for a coal-based shaft furnace. This patent adopts a bottom discharge method and includes at least one discharge unit. Each discharge unit includes: three cooling box system...
