According to the adjustable combined type tuyere blowpipe disclosed by the utility model, the damaged section is the wearing section, and a new combined type tuyere blowpipe is formed by replacing a new wearing section and fixed section combination; therefore, the consumption and process cost of the raw material are reduced, the effect of reducing the production cost of the enterprise is achieved; when in use, the length can be adjusted according to actual demand and the adaptability is good.
Description
Technical field
The utility model relates to a kind of adjustable combination type air port belly pipe.
Background technology
In fused(calcium magnesium)phosphate and smelting industry air-supply apparatus of blast furnace, because blow bustle pipe and swan neck are all fixed, cannot move, and the last furnace shell shell deformation that causes uneven in temperature causes the long and short requirement of belly pipe with regard to disunity.Generally consider from theory, blast-furnace tuyere belly pipe is designed to T-shaped screw thread and adjusts, but in actual use, while use for the first time except new belly pipe, can adjust; After using once, due to the adhesion of various dirts be heated, T-shaped screw thread distortion causes adjusting, therefore design a kind of adjustable Combined air outlet belly pipe, both can solve shell deformation length and require skimble-scamble situation, avoid again burning out because of air port belly pipe the waste of integral replacing.
Summary of the invention
The purpose of this utility model is just to provide a kind of adjustable combination type air port belly pipe, to solve the problems referred to above that exist in current air-supply apparatus of blast furnace.
The technical scheme of taking: adjustable combination type air port belly pipe, air port belly pipe is assembled into by rapid wear section 1, canned paragraph 3 and adjusting pad 2 sockets, canned paragraph 3, rapid wear section 1 are all made tubular, the former is sleeved on the latter's back segment, adjusting pad 2 is made the annular cover on the back segment 4 that can be tightly placed in rapid wear section 1, is arranged between canned paragraph 3 and the connection section of rapid wear section 1.
Wherein, the leading portion outer wall of rapid wear section 1 and the outer wall of canned paragraph 3 are made identical taper shape, and back segment outer wall is made cylindrical, and the inner chamber of whole rapid wear section 1 is made circular cavity, and the adjoiner of front and back section is shaped with annular snap platform 5.
The length of canned paragraph 3 is at least 2.5 times of rapid wear section 1 length, and the inner chamber of canned paragraph 3 is tapered, and the front end sleeve of conical cavity is stuck on the back segment 4 of rapid wear section 1; The length of the back segment 4 of rapid wear section 1 is greater than 1.2 times of leading portion 6 length; The selection of the internal diameter size of adjusting pad 2 with can be tightly placed in rapid wear section 1 back segment 4 periphery determine.
The adjustable combination type air port belly pipe of making like this, the just rapid wear section of damaging in use, the rapid wear section more renewing and canned paragraph combination, just form new Combined air outlet belly pipe.Thereby can reduce raw-material consumption and processing charges, reach the effect that reduces enterprise's production cost.In use, length can be discussed according to actual requirement adjustment, and adaptability is good.
Accompanying drawing explanation
Fig. 1 is adjustable combination type air port belly pipe structural representation.
Sequence number explanation in figure: the 1st, rapid wear section, the 2nd, adjusting pad, the 3rd, canned paragraph, the 4th, back segment, the 5th, annular snap platform, the 6th, leading portion.
Embodiment
Below in conjunction with accompanying drawing, as embodiment, scheme is further illustrated.
With reference to Fig. 1, in fused(calcium magnesium)phosphate and smelting industry air-supply apparatus of blast furnace, air port belly pipe is made of one, thereby after current damaged on end is bad, whole air port belly pipe just becomes waste product.Cause the waste of material, device rate of utilization is low.The utility model adopts canned paragraph 3 and rapid wear section 1 to be socketed into an air port belly pipe, and the requirement changing in order to adapt to length, has made adjusting pad 2, like this, can according to actual needs, increase the total length of air port belly pipe.Concrete mode is that canned paragraph 3 is made into a truncated cone-shaped body that has tapering, and its front end oral area internal diameter is applicable to back segment 4 tight fit connections with rapid wear section.The outer wall of the leading portion 6 of rapid wear section 1 coincide and is connected with canned paragraph; The back segment 4 of rapid wear section 1 stretches in the inner chamber of canned paragraph 3; The inner chamber of rapid wear section 1 is processed into cylindrical cavity, is communicated with canned paragraph inner chamber.
Back segment 4 outer walls of rapid wear section 1 are processed into cylindrical, and the internal diameter of its Outside Dimensions and adjusting pad 2 matches.Be that adjusting pad 2 can tightly be sleeved on the cylinder of back segment 4.The back segment 4 of rapid wear section 1 engages position with its leading portion 6, is shaped with an annular snap platform 5 that exceeds cylinder, so that be enclosed within adjusting pad 2 on rapid wear section back segment 4 clamped condition in canned paragraph front end and this annular snap platform.
Make multiple adjusting pads 2 for subsequent use, so that using as required one, the adjusting pad 2 of two or more numbers is inserted on rapid wear section 1 back segment 4, pull open the distance between the front end of canned paragraph 3 and the card platform 5 of rapid wear section 1, thereby increase the length of whole air port belly pipe.
The air port belly pipe of making like this, canned paragraph 3 can be not damaged, only need to change rapid wear section, can re-assembly a new air port belly pipe.And use adjusting pad 2 to make the length of air port belly pipe reach the requirement of use.
1, rapid wear section: be hot-air channel, for canned paragraph and water tank are connect, and hot blast sent into blast-furnace tuyere water tank, easily change after damaging, weight is less, and tooling cost is low, and can be processed into the skimble-scamble spare part of length;
2, adjusting pad: be mainly used in adjusting air port length and require skimble-scamble occasion,, when last furnace shell is out of shape when serious, when rapid wear section and canned paragraph length are inadequate, adjust with this;
3, canned paragraph: be hot-air channel, be mainly used in rapid wear section and swan neck to connect.
Adjustable combination type air port belly pipe is a kind ofly to provide light and handy, easy and save a kind of blast-furnace tuyere air-supply belly pipe device of tooling cost for blast-furnace smelting enterprise.Rapid wear section 1 designs as far as possible and shortens, to save tooling cost, diameter is pressed blast furnace wind-engaging capacity calculation; Canned paragraph 3 deducts rapid wear section 1 length by the distance between blast furnace swan neck and air port water tank and carries out Design of length, because this section is in use except being not intended to damage, generally not fragile, thus Design of length is arrived to the limit as far as possible, and be designed to regular length; Adjusting pad 2 is processed into different thickness, utilizes it to adjust in order to shell deformation canned paragraph 3 and rapid wear section 1 length when inadequate.In design process, canned paragraph 3 is designed to fixed measure, and this section of weight is strengthened as far as possible; Consumable accessory is processed into different in size, in order to according to practical situation, selects satisfactory rapid wear section to coordinate with canned paragraph and adjusting pad, the requirement while making the length adaptation dimensional change of air port belly pipe large.
