Abstract

The utility model discloses a 20 kg electric heating cokery for test used in coking research, comprising a cokery body 2, a combustion chamber 4, a carbonization chamber 5, a rise pipe 6, a cokery door 3, a coal holding box 11, a cokery door car 9, a lifting platform 14, an electric heating element 8, a control instrument, etc. The utility model is characterized in that the cokery door 3 and the cokery door base are fixed on the cokery door car 9, and the supporting board 12 of the coal holding box and the coal holding box 11 are arranged on the cokery door 3. The opening and closing of the codery door 3 can be realized through the lifting platform 14. The coal holding box 11 on the cokery door car 9 can move horizontally by utilizing a trackway 15, which is convenient for the coal charging and the coke extracting. The utility model can be used in the laboratory to carry out the coking stimulating test, and the result of the test is closed to the actual production. The 20 kg electric heating cokery for test has the advantages of little pollution and simple operation.

Description

20 kilograms of electrically heated testing coke ovens

A kind of 20 kilograms of electrically heated coke ovens belong to the testing apparatus that coking is studied.

Carry out coking test research at laboratory stage at present and adopt 20 kilograms of electrically heated testing coke ovens mostly.200 kilograms of testing coke ovens are half type approval test coke oven, though it can more accurately simulate the production reality of industrial coke oven, shortcoming is that sample size is big, the test period is long and labour intensity is big.Small-scale test coke oven (as 5 kilograms of electrically heated testing coke ovens etc.) is though can overcome above-mentioned shortcoming, and its experimental result is with to produce actual dependency poor.Chinese patent once disclosed a kind of 20 kilograms of electrically heated testing coke ovens (90209603.6), advantages such as this utility model has sample dosage little (23 kilograms of dry coals), the sample cycle is short, labour intensity is little, but design such as discharge of the coke that furnace roof is coaling because this utility model adopts, furnace bottom opens the door, in use still have defective: carry out the furnace roof coal when the coking chamber temperature is 800 ℃ of left and right sides, the flue gas of its generation easily pollutes Working environment; Coke easily sticks on the charing locular wall in the process of coking, after coking finishes, must be through manually disclosing Jiao, and coke could break away from coking chamber.

The purpose of this utility model is to provide a kind of experimental result and actual being close of production of coking, is convenient to coaling and discharge of the coke, and Working environment is polluted 20 kilograms of electrically heated test coke ovens little, simple to operate.

For achieving the above object, the technical solution of the utility model is as follows: a kind of 20 kilograms of electrically heated coke ovens that are used for coking research, by furnace shell 1, body of heater 2, fire door 3, coking chamber 4, combustion chamber 5, upcast 6, coke oven support 7, compositions such as an electric heating element 8 and electric control instrument, it is characterized in that: fire door 3 is fixed on the fire door base 10 on the fire door car 9 that can move horizontally, the coal bin of Sheng supporting plate 12 is arranged on fire door 3 tops and contain coal bin 11 so that coaling and discharge of the coke, be closed furnace door, on the platform between fire door 3 and the fire door base 10, be provided with fire door thermal-insulating sealing layer 13, on lifting gantry 14, be provided with the track 15 that fire door car 9 is moved, with lifting gantry stabilizer bar 16 corresponding holes 17, the shack 21 that is connected with ring chain 20 is by electric motor 18, step-down gear 19 is controlled lifting gantry 14 and is made fire door 3 switches.

Embodiment is described further the utility model in conjunction with the accompanying drawings:

Fig. 1 is side-view of the present utility model (body of heater office is cutd open);

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the floor map of the utility model lifting gantry 14.

Top of the present utility model comprises furnace shell 1, body of heater 2, coking chamber 4, combustion chamber 5, upcast 6, an electric heating element 8 etc., wherein, build by laying bricks or stones with extraordinary silicon carbide brick in the both sides of burner hearth combustion chamber 5, and in the combustion chamber of both sides, evenly place 4 U type an electric heating element 8---silication molybdenum bar respectively, the upcast 6 in coking chamber 4 upper ends can discharge the flue gas that produces in the coking.Bottom of the present utility model is by coke oven support 7, lifting gantry stabilizer bar 16, lifting gantry 14, fire door 3, fire door base 10, fire door car 9, electric motor 18, compositions such as step-down gear 19 and chain 20, on fire door 3, be Sheng coal bin supporting plate 12 and Sheng coal bin 11, contain coal bin 11 for being the high temperature resistant steel plate of rectangular parallelepiped cartridge type, on the platform between fire door 3 and the fire door base 10, be fixed with the thermal-insulating sealing layer 13 of pure aluminium silicate asbestos mat, on lifting gantry 14, be provided with track 15, and it is corresponding with external track, fire door car 9 can be moved in the horizontal direction, and four shacks 21 are separately fixed on four ring chains 20.

The test-results of utilizing utility model to carry out coking test research and 200 kilograms of testing coke ovens compares its shatter strength (M ₄₀) value correlation coefficient r=0.912, abrasive wear resistance (M ₁₀) value correlation coefficient r=0.920.

Comprehensive the foregoing description, the utlity model has that sample dosage is little, the test period is short, with the good advantage of dependency of the comparative test result of 200 kilograms of testing coke ovens, in addition, because the utility model adopt to be contained on the coal bin coal and is discharged of the coke, make process of coking simple, both alleviated labour intensity, reduced in the process of coking pollution again environment.
