Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: an improved method of a discharging adjusting device of a star discharger comprises the following specific operations:
s1, preparing three flat steels with the width of 10mm, the length of 70mm and the thickness of 6mm, removing burrs and preparing 506-type welding rods;
s2, sequentially detaching the star-shaped discharger, loosening the original adjusting plate fixing bolt, adjusting the adjusting plate upwards by 3mm, fastening the fixing bolt, and welding three flat steels on the inner walls of the original adjusting plate and the star-shaped discharger by using a welding rod of type 506, wherein the straight lines of the three flat steels are parallel to each other, and the distance between the central points of the two flat steels on the outermost sides is 92 mm;
and S3, cleaning the welding spot skin, knocking to check the welding strength, and after confirming that no problem exists, reinstalling the star discharger and performing power connection operation.
When the material gravity settling device works, the material active coke flows to the impeller position of the star-shaped discharger from the upper part along the shell through gravity, and the material gravity settling speed is adjusted through the height of the adjusting plate; at the moment, the motor is started, and the chain gear drives the impeller to rotate to unload the materials;
after improvement, 3 pieces of flat steel are welded at the lower part of an original adjusting plate, one end of the flat steel is welded on the adjusting plate, the other end of the flat steel is fixed on the inner wall of a star-shaped discharger, and the section of a material flowing through the adjusting plate is equally divided into 4 areas through the flat steel; and a conical gap (as shown in figure 4) is formed when the material flows through the flat steel, so that the material can have enough moving space when the star-shaped discharger is fed by an impeller, and the material biting condition is avoided;
in order to ensure that the material quantity passing through the adjusting plate is not lower than 1m3/h in the same time, the cross section area is required to be ensured to be unchanged by ensuring that the flow passing through the adjusting plate is unchanged and the influence of the gravity and the rotating speed of the impeller is unchanged through a formula Q (flow) ═ v (flow speed) × S (cross section area). 3 flat steel strips are added on the cross section, the material flow area is reduced, and the adjusting plate needs to be adjusted upwards. By calculating: the original cross section area is 184 × 50 × 9200mm2, the adjusting plate is adjusted upwards by x, and x is 2.9mm when 184 × 50+ x-10 × 50+ x is 9200. After the adjusting plate was moved upward by 3mm as a whole, 3 flat steels each having a width of 10mm and a thickness of 6mm were welded at intervals as shown in FIG. 4. The other end of the flat steel is fixed on the inner wall of the star-shaped discharger.
The embodiment is as follows:
the invention discloses a discharging adjusting device of a star discharger, which is applied to a desulfurization and denitrification project of flue gas of a coke oven with the diameter of 7.63 meters in a steed coking total plant in 2020 and 5 months. Operation effect proves, can guarantee the stability of material circulation completely, has solved the inside material of stinging of star type tripper, star type tripper rotor serious wear scheduling problem basically.
The specific benefit is calculated as follows:
counting that the number of times of failure shutdown caused by material blockage per month of 24 star-shaped dischargers is up to 69 times before the star-shaped discharger is not modified with an adjusting device; when all the devices are adjusted to be modified adjusting devices, the monthly mean failure rate is reduced to 7 times. The maintenance frequency is reduced by 62 times per month averagely, the maintenance time of a maintenance work order is 1 hour each time, two fitters are required to maintain, one operator is required to cooperate, and the staff salary is 25 yuan per hour. Saving labor cost 3 x 62 x 1 x 25-4650 yuan per month.
Since star-shaped dischargers frequently bite materials, the abrasion of inner lining plates and impellers is very serious, 12 impeller parts are replaced in 3 months in 2020 since 8 months in 2019, and the cost of consumption is 5000 x 12 to 60000 yuan every half year. The man-hour of replacement is about 3 hours, 3 bench workers and 1 electrician are needed to carry out the replacement operation, and the labor cost is 3 × 5 × 25 × 12 × 2 (removal and installation) is 9000 yuan. After the star-shaped unloader adjusting plate is modified in 5 months in 2020, the condition that the impeller of the star-shaped unloader is worn and needs to be replaced does not appear in 12 months till now.
In conclusion, the improved method of the discharging adjusting device of the star-shaped discharger aims at the problem that the star-shaped discharger has the phenomenon of motor overcurrent stalling in high frequency in the material circulation of the active coke desulfurization and denitrification system, the discharging adjusting device can effectively reduce the number of times of fault stalling of the star-shaped discharger, prolong the service life of the star-shaped discharger, reduce the abrasion of the rotor of the star-shaped discharger and improve the economic operation capacity of the variable frequency motor of the star-shaped discharger.
