Embodiment Construction

[0023] Such as figure 1 , figure 2 As shown, the best implementation mode of the shut-off door for the dry-type slag discharger of the present invention, the door seat 1 of the shut-off door device is installed between the slag hopper 6 and the dry-type slag discharger 7 . The door seat 1 is provided with left and right door panels 2a, 2b running opposite to each other horizontally. The left and right door panels 2a, 2b are installed on the horizontal track 4. Between the horizontal track 4 and the door seat 1 is a fixed rigid body. The left and right door panels 2a, 2b are respectively connected to the first driving mechanism 3a, the second driving mechanism 3b, the third driving mechanism 3c, and the fourth driving mechanism 3d through the connecting rod 8. The first drive mechanism 3 a , the second drive mechanism 3 b , the third drive mechanism 3 c , and the fourth drive mechanism 3 d can be driven electrically or hydraulically, and are fixed on the door seat 1 . In o...

Abstract

The invention discloses a shutting door for a dry-type slag-discharging machine. The shutting door for the dry-type slag-discharging machine comprises a door seat (1) arranged between a slag funnel (6) and the dry-type slag-discharging machine (7), and door plates (2a and 2b) movably arranged on the door seat (1) and used for separating the slag funnel (6) from the dry-type slag-discharging machine (7). Compared with the prior art, the shutting door for the dry-type slag-discharging machine has the advantages of convenience of examination and repair, low examination and repair cost, smooth transportation and higher safety.

Description

technical field [0001] The invention relates to a shut-off door for a dry-type slagging machine, in particular to a shut-off door device for overhauling the dry-type slagging machine under the condition of not stopping the furnace. Background technique [0002] With the improvement of national energy-saving, water-saving and environmental protection requirements, dry slag removal in coal-fired thermal power plants has become the first solution for boiler slag removal. The dry slag removal system uses the convective movement between the ambient cold air and the hot slag to exchange heat, so that the hot slag is cooled and then discharged. After being heated, the ambient cold air enters the furnace under the negative pressure of the furnace to participate in combustion. The key equipment to complete the above process is the dry slag discharger. [0003] The dry slag discharger and its system equipment are composed of many sets of independent equipment. During the operation o...
