Abstract:
A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

Claim (Index 17):
A precise controlled internal heating type electric furnace, characterized in that the precise controlled internal heating type electric furnace comprises a heat preserving cylinder body ( 14 ), and a top portion of the heat preserving cylinder body ( 14 ) is provided with a group of heat preserving furnace top doors ( 15 ) which can be opened and closed; the heat preserving furnace top doors ( 15 ) thereon are provided with a tank body sintering hanger self-rotating piece ( 16 ) which penetrates through the heat preserving furnace top doors; a bottom portion of the tank body sintering hanger self-rotating piece is further provided with a planar electric furnace ( 11 ), and a bottom surface of the planar electric furnace is provided with a group of electric heating elements; the precise controlled internal heating type electric furnace further comprises a main body heating electric furnace ( 7 ) in the heat preserving cylinder body ( 14 ); the main body heating electric furnace ( 7 ) sequentially comprises a ring body planar electric furnace ( 10 ), a multilayer regionally-combined cylindrical electric furnace ( 8 ) and a truncated-cone step-shaped electric furnace ( 9 ) from bottom to top; a ring body planar furnace lifting piece ( 17 ) is further provided below the ring body planar electric furnace ( 10 ); the ring body planar electric furnace ( 10 ) consists of a ring planar electric furnace ( 10 a ) and a straight ring body electric furnace ( 10 b ); a ring plane of the ring planar electric furnace ( 10 a ) thereon is provided with a plurality of turns of concentric circular grooves with different diameters; a group of electric heating elements ( 12 . 18 ) are wound in the concentric circular grooves; an inner circumferential wall of the straight ring body electric furnace ( 10 b ) is provided with a plurality of ring grooves from bottom to top; a group of electric heating elements ( 12 . 19 ) are wound in the ring grooves; the multilayer regionally-combined cylindrical electric furnace ( 8 ) is formed by stacking a plurality of layers of circular flat plates ( 8 a ) with the same diameter and central axes which are overlapped, outer circumferential walls of the circular flat plates are provided with ring grooves, and a group of electric heating elements ( 12 . 1 - 12 . 16 ) are wound in the ring grooves of every 2-8 layers; the truncated-cone step-shaped electric furnace ( 9 ) is formed by stacking a plurality of circular flat plates ( 9 a ) with different diameters and central axes which are overlapped, the diameters of the circular flat plates ( 9 a ) are successively decreased from bottom to top to form a step-shaped circular platform, a group of electric heating elements ( 12 . 17 ) are wound in every 2-8 layers of step-shaped platform surfaces, a seal-head-shaped heating structure component ( 9 b ) which is structurally fit and consistent with an inner wall of the seal head ( 3 a 2 ) of the inner cylinder body covers a periphery of the truncated-cone step-shaped electric furnace ( 9 ), and the seal-head-shaped heating structure component is made of heat-resistant steel; and all groups of electric heating elements in the precise controlled internal heating type electric furnace are respectively connected with a temperature control system.
