Abstract
The utility model belongs to the technical field of cement production equipment, provides a valve plate for a tri-air-lock valve of a raw material vertical mill, and relates to an improvement based on the existing valve plate for a tri-air-lock valve of a raw material vertical mill. The valve plate is characterized by comprising a valve plate body, wherein the valve plate body is divided into three valve plate branch bodies, the first valve plate branch body is a heat-resistant plate, and the bottom of the first valve plate branch body is fixedly provided with four rib plates. According to the utility model, the abrasion cycle of the valve plate for a tri-air-lock valve can be effectively prolonged, and the equipment utilization rate is improved.
Description
Technical field
The utility model belongs to the cement manufacture plant technical field, relates to a kind of raw material roller mill three road air valve valve plates.
Background technology
The place often is equipped with one of 1200x800mm three road air valve at some cement production enterprise raw material roller mill feeding mouths, and three valve plates of existing three road air valves are opened successively and closed by three Hydraulic Cylinders independently.The valve plate material is 8+8mm high-chromium alloy hardfacing composite plate, and for increasing the service life, valve base plate, both sides side plate have all covered the high Chrome alloy abrasion-proof build-up composite plate of one deck 8+8mm, i.e. liner plate.In order to make lining plate replacing convenient, the screw rod of burn-oning on the motherboard layer of the liner plate back side again passes the motherboard circular hole of valve base plate and side plate, is tightened by bolts.It is high that 140mm is separately installed in valve base plate bottom, and width is with the unidimensional air chamber of valve base plate, and the relatively moistening or winter temperature of weather will pass into hot blast in the time of lower, base plate is heated, thereby material is dried, and guarantees that blanking is unobstructed.But for being in regional climate temperature relatively high enterprise, air chamber does not all have to use always.When reality was used, valve plate and inner wear liner were too fast, and on average do not surpass 3.5 months service life, arrived the wearing and tearing later stage, material directly pours in mill from discharging point, causes again the heavy wear of center tremie pipe, grinding machine leaks out seriously, and fluctuation of operating conditions is large, and the production that has restricted enterprise is carried out.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of raw material roller mill three road air valve valve plates, and this valve plate has wear-resisting and characteristic long service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that designed raw material roller mill three road air valve valve plates comprise valve plate, and described valve plate divides three road valve plates, and the first valve plate is refractory plate, sets firmly four road gussets in the bottom of first valve plate.
The utility model adopts the designed raw material roller mill three road air valve valve plates of technique scheme, owing to changing original first valve plate into refractory plate, and be provided with the reinforcement gusset in the bottom of first valve plate, can effectively extend the wear-out period of three road air valve valve plates, improve the utilization rate of equipment.

Fig. 5 represents the structural representation of the utility model base plate.
The specific embodiment
Illustrate below in conjunction with the structure of accompanying drawing to the utility model raw material roller mill three road air valve valve plates.
Referring to Fig. 1, Fig. 2, Fig. 1 represent the structural representation before valve plate improves, and valve plate 1 material is 8+8mm high-chromium alloy hardfacing composite plate, and the valve plate of this kind structure wears no resistance, and on average uses 3.5 months.
Referring to Fig. 3, Fig. 4, Fig. 5, the utility model raw material roller mill three road air valve valve plates comprise valve plate 1, and wherein, valve plate divides three road valve plates, the valve plate 1 of first is refractory plate, its material selection 1Cr8Ni9Ti, and thickness changes 16mm into to strengthen abrasion resistance by original 14mm, set firmly four road gussets 2 in its bottom, the same motherboard of the material of gusset 2, its thickness are 14mm, and wide is 60mm, length is with the width of valve plate, and the spacing of each gusset is 50mm.Second and third road valve plate and side plate material, structure are still by former design and installation method.During fabrication and installation, base plate 3 motherboards are sliced off not together with liner plate, be material the steel plate bar of Q235, specification 16x200x1200mm, to air chamber, air chamber be divided into some sulculuses along the vertical position welding of valve width, after filling completely by broken material, to realize material and the friction of expecting.
