Referring to fig. 1 to 8, an embodiment of the present invention provides a pushed slab kiln for self-cleaning impurities in the kiln, which includes a kiln body 10, a plurality of crucibles 20 and cleaning devices 30, the crucibles 20 are arranged inside the kiln body 10, the crucibles 20 are used for containing materials for processing (e.g. sintering or roasting), the crucibles 20 are arranged side by side in sequence, adjacent crucibles 20 are in close contact with each other, at least one cleaning device 30 is arranged between two adjacent crucibles 20, the cleaning devices 30 and the crucibles 20 have the same external shape, the cleaning devices 30 are regular bodies, a first vertical groove 31 extending towards a core is arranged on an upper surface of the regular body, a left vertical groove 32 and/or a right vertical groove 33 extending towards the core is arranged on a left side surface and/or a right side surface of the regular body, a first scraping block 311 is arranged inside the first vertical groove 31, and the height of the scraping block is higher than the upper surface, the left scraping and grinding block 321 and/or the right scraping and grinding block 331 are arranged in the left vertical groove 32 and/or the right vertical groove 33, and the surface height of the left scraping and grinding block 321 and the right scraping and grinding block 331 is higher than that of the upper surface. In this scheme, the widths of the left scraping and grinding block 321 and the right scraping and grinding block 331 are flush with the left side surface and the right side surface of the regular body, and do not have scraping and grinding effects on the left side wall and the right side wall of the kiln body 10.

The cleaning device 30 of the scheme is not required to be driven independently and operated independently, is driven synchronously by the driving mechanism of the crucible 20 and moves synchronously with the crucible 20, the cleaning process is continuous and uninterrupted, the sintering work of the kiln is normally carried out, the cleaning is carried out while sintering, and the working efficiency of the kiln body 10 is not influenced completely.

Further, the left side of the left scraping block 321 protrudes from the left side of the regular body and/or the right side of the right scraping block 331 protrudes from the right side of the regular body. In this scheme, can scrape simultaneously two lateral walls on the left and right of the kiln body 10, also can scrape a lateral wall.

The cleaning device 30 of the scheme is at least four embodiments, one is suitable for the kiln body 10 of the single-row crucible 20, namely the cleaning device 30 is provided with a first vertical groove 31, a left vertical groove 32 and a right vertical groove 33, and has cleaning effects on the upper surface, the left side surface and the right side surface; the other is that the vertical grooves are only arranged on the upper surface and the left side surface; the third is to set vertical slots on the upper surface and the right side surface, and the fourth is the deformation of the first, namely the left scraping and grinding block 321 and the right scraping and grinding block 331 do not protrude, but only scrape and grind the upper surface under the combined action of the left scraping and grinding block 321 and the right scraping and grinding block 311; the second and third combinations are suitable for the kiln body 10 of the double-row crucible 20; the fourth scheme is matched with the second scheme and the third scheme, and is suitable for the kiln body 10 with three rows of crucibles 20. By analogy, the kiln furnace structure can be suitable for multi-column kilns, all of which are variants of the embodiment of the application and fall into the protection scope of the application.

Further, the cleaning device 30 is a solid body. The vertical grooves in three modes are formed in the solid body, so that the mechanical processing is more convenient, the strength is high, the vertical grooves do not deform due to extrusion when moving synchronously with the crucible 20, and the service life is long.

Further, the widths of the left scraping block 321, the right scraping block 331, and the first scraping block 311 entirely cover the width direction of the upper surface of the solid body. So that the upper surface of the solid body forms the top of the full-coverage scraped kiln body 10 which is not less than the width direction of the solid body and has no omission in the middle inside the kiln body 10.

Further, a plurality of first adjusting blocks 312 are arranged in the first vertical groove 31 below the first scraping and grinding block 311, and the plurality of first adjusting blocks 312 have thicknesses and are used for adjusting the height of the first scraping and grinding block 311 exposed out of the upper surface; a plurality of left adjustment blocks 322 and/or right adjustment blocks 332 are also disposed within left vertical slot 32 and/or right vertical slot 33.

The scraping and grinding block is made of high-strength and high-wear-resistance materials, and the adjusting block is at least a common cushion block, so that the scraping and grinding block is not required to be replaced after being worn in order to save cost and be used for multiple times, and only the adjusting block is required to be heightened. When the height of the scraping and grinding block is equal to the upper surface, the scraping and grinding block cannot play a role in cleaning, at this time, a first adjusting block 312 is added into the first vertical groove 31, the first scraping and grinding block 311 is lifted, or when the height needs to be adjusted although the first scraping and grinding block is not worn, the first adjusting block 312 can also be added. The same applies to the adjustment of the left scraping block 321 and the right scraping block 331.

Further, a limiting block 34 is arranged between the first vertical groove 31 and the first scraping and grinding block 311, and limiting blocks 34 are arranged between the left side scraping and grinding block 321 of the left side vertical groove 32 and between the right side vertical groove 33 and the right side scraping and grinding block 331. The clamping scraping and grinding block is clamped with the vertical groove to avoid shaking.

Further, the crucible 20 is a cube or a rectangular parallelepiped, and the cleaning device 30 has the same outline shape as the crucible 20. The same shape can ensure that the cleaning device 30 and the crucible 20 are placed neatly, and the cleaning device 30 is stable, has no displacement or dislocation when moving along the guide rail, and meanwhile, the arrangement mode of the crucible 20 cannot be influenced by the cleaning device 30.

Further, there are two cleaning devices 30, the crucibles 20 are arranged in two rows in the kiln body 10, one cleaning device 30 is arranged for each row of crucibles 20, and each cleaning device 30 is arranged between two adjacent crucibles 20; the two cleaning devices 30 of the two rows of crucibles 20 are arranged in parallel in a row or staggered front and back.

These are two schemes, as shown in fig. 3 and 4, respectively. The scheme is suitable for the scheme that one row, two rows or multiple rows of crucibles 20 are arranged in the kiln body 10, one cleaning device 30 is correspondingly arranged in each row, the cleaning devices 30 in each row can just form one row or can be staggered front and back, and the cleaning devices fall into the protection range of the scheme. When the front and the back are arranged in a staggered manner, the friction force between the cleaning device 30 and the inner wall of the kiln body 10 can be reduced. The two rails are provided with the two main thrust oil cylinders, and the two cleaning devices are arranged in a staggered manner, so that the condition that the main thrust of the two rails is too large to cause the crucible damage and kiln blockage can be prevented; in the cleaning process, the cleaning of the kiln top and the side wall can be realized by adjusting the pressure of a single main push oil cylinder; the enriched impurity position and the enriched impurity condition of the kiln can be effectively judged by monitoring the pressure of the single main push oil cylinder. Although the position of the impurity enrichment area in the kiln body can be obtained through theoretical calculation reasoning, and according to process control, the time and the unit time advance distance of each furnace product from the furnace entering to the furnace discharging can be controlled, the production process cannot be monitored through an external detection means, and the scheme can objectively and accurately reflect and calculate the position of the impurity enrichment in the kiln body by monitoring the pressure change condition of the main thrust cylinder and combining with the process execution time. For example, a row of crucibles, a main thrust cylinder has a stable thrust of F1, when the change of F1 reaches 20%, it indicates that an impurity-enriched zone is encountered, and then the impurity-enriched position can be calculated according to the travel distance of the crucible controlled in the process.

Further, a rail 11 is arranged inside the kiln body 10, the crucible 20 is placed on the rail 11 and slides relative to the rail 11, a driving mechanism is arranged outside the kiln body 10, and the output end of the driving mechanism is in contact with the crucible 20 at the head part and is used for pushing the crucible 20 to move along the rail 11.

A method for self-cleaning impurities in a pushed slab kiln comprises the following steps:

the crucibles 20 to be treated are arranged in parallel in the kiln body 10, and at least one cleaning device 30 is arranged between two adjacent crucibles 20;

the cleaning device 30 is contacted with the top and the side wall of the kiln body 10, the crucible 20 moves to drive the cleaning device 30 to move synchronously, and the moving cleaning device 30 cleans impurities in the kiln body 10 in a scraping and grinding mode.

Further, a vacant crucible 20 is arranged in front of the cleaning device 30 for receiving the impurities scraped by the cleaning device 30. Along with crucible 20 and cleaning device 30 forward movement, cleaning device 30 scrapes off the inside impurity of kiln body 10, drops inside a crucible 20 that is close to in the front, because sintering treatment crucible 20 is uncovered, to some less or careful materials, the falling-in of impurity can cause the material to mix into impurity or be polluted, so add a control crucible 20, be used for accepting impurity specially, when guaranteeing that cleaning device 30 and other crucibles 20 normally work, still solved this problem.

The modules or units in the device of the embodiment of the invention can be combined, divided and deleted according to actual needs.
