Description

Technical Field

[0001] The utility model relates to the technical field of grate plate adjustment, in particular to a grate plate gap adjustment mechanism for a grate cooler. Background Art

[0002] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. At the same time, it provides hot air for rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system. Grate cooler is a quenching cooler. After the material enters the cooler from the kiln, it is spread on the grate plate to form a material layer of a certain thickness. The cold air blown in passes through the material layer moving on the grate bed in perpendicular directions to cool the clinker quenchly.

[0003] For example, the patent document with the announcement number CN 209263683 U discloses a grate plate of a grate cooler with adjustable gap, including a grate plate, an air inlet hole is opened at the bottom of the grate plate, a threaded rod is threadedly sleeved on one side of the bottom of the inner cavity of the grate plate, a threaded sleeve is threadedly sleeved on the top of the outer surface of the threaded rod, and a bearing is fixedly sleeved on the outer surface of the threaded sleeve, a U-shaped plate is fixedly installed on the top of the threaded rod, and a fixed rod is fixedly sleeved in the middle of the front side of the U-shaped plate, one end of the fixed rod passes through the back of the threaded sleeve, and a sealing plate is movably sleeved in the middle of the outer surface of the fixed rod. The grate plate of the grate cooler with adjustable gap facilitates better adjustment of the gap of the U-shaped plate through the mutual cooperation between the fixed rod, the sealing plate, the connecting rod and the telescopic rod, thereby solving the problem that the gap on the U-shaped plate cannot be changed and the gap of the U-shaped plate at different positions needs to be customized, thereby improving the adjustability of the gap.

[0004] However, in actual use, this structure can only perform simple manual gap adjustment operations on the grate cooler grate plates. However, when cement clinker is actually produced, manual adjustment is dangerous and is prone to adjustment deviations. At the same time, the equipment cannot adjust the cement clinker at the gap between the two sets of grate plates to quickly guide and transport the cement clinker, which cannot meet daily use needs. Therefore, it is urgent to design a grate cooler grate gap adjustment mechanism to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a grate cooler grate plate gap adjustment mechanism to solve the problem that the existing structure proposed in the above background technology can only perform simple manual gap adjustment operation of the grate cooler grate plate during actual use. However, when cement clinker is actually produced, manual adjustment has certain risks and is prone to adjustment deviations. At the same time, the equipment cannot adjust the cement clinker quickly at the gap between the two groups of grate plates, and cannot meet the daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a grate plate gap adjustment mechanism for a grate cooler, comprising a U-shaped slide, a center frame is fixedly connected to the top center of the U-shaped slide, a diverter strip is arranged at the top of the center frame, a retractable groove is opened on both sides of the center frame, and a retractable folding cover is movably connected to the inside of the retractable groove;

[0007] A first grate plate and a second grate plate, one end of the U-shaped slide is movably connected with the first grate plate, the other end of the U-shaped slide is provided with the second grate plate, and the bottom ends of the first grate plate and the second grate plate are fixedly connected with a limited position slide.

[0008] Preferably, a first electric push rod is disposed at the bottom of the first grate plate via a limiting slide, and a second electric push rod is disposed at the bottom of the second grate plate via a limiting slide.

[0009] Preferably, positioning slide bars are fixedly connected to both sides of the position limiting slide.

[0010] Preferably, a limiting slide groove is provided on the inner bottom wall of the U-shaped slide, and positioning slide grooves are provided on both sides of the inner wall of the limiting slide groove.

[0011] Preferably, an adjustment groove is provided on the surface of the U-shaped slide, and the adjustment groove is matched with the first grate plate and the second grate plate.

[0012] Preferably, a damping rubber pad is provided on the inner wall of the center frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The grate plate gap adjustment mechanism of the grate cooler can enable the equipment to perform a highly stable adjustment operation of the gap between the grate plates on the grate cooler through the U-shaped slide, the first grate plate, the second grate plate, the limit slide, the first electric push rod, the second electric push rod, the positioning slide bar, the limit slide groove, the positioning slide groove and the adjustment groove. In the actual use process, the staff first installs the first grate plate and the second grate plate on both sides of the center frame inside the U-shaped slide through the limit slide at the bottom, and then starts the first electric push rod and the second electric push rod between the two sets of limit slides. The second electric push rod enables the two sets of limit slides to drive the first grate plate and the second grate plate on their top to perform gap adjustment operations around the center frame inside the adjustment groove of the U-shaped slide, thereby meeting the daily use needs of the grate cooler. At the same time, when the limit slide is moved and adjusted inside the limit slide groove of the U-shaped slide, the positioning slides on both sides thereof can perform limit sliding operations inside the positioning slide grooves on both sides of the inner wall of the limit slide groove, and quickly perform positioning and fixing operations, thereby ensuring the stability of the subsequent use of the first grate plate and the second grate plate, and reflecting the practicality of the equipment design.

[0015] The grate plate gap adjustment mechanism of the grate cooler further improves the overall use effect of the equipment by means of the U-shaped slide, center frame, diverter strip, retractable groove, retractable folding cover, first grate plate, second grate plate and damping rubber pad. In daily use, the staff can install the retractable folding covers on both sides of the center frame on the opposite end of the first grate plate and the second grate plate. Then, when the gap between the first grate plate and the second grate plate is adjusted, the retractable folding cover can be adaptively retracted and extended inside the retractable groove of the center frame, thereby providing cover protection between the first grate plate and the second grate plate and the center frame of the U-shaped slide. At the same time, in conjunction with the diverter strip on the top of the center frame, the cement clinker can be diverted to the first grate plate and the second grate plate on both sides when the grate cooler is working, which reflects the comprehensiveness of the equipment design.
