Abstract

A conveyor tail sealing structure comprises box side plates, a sliding plate, a slide and a tail shaft. A sealing box is arranged on the sliding plate, sealing materials contacting with the circumferential surface of the tail shaft are filled in the sealing box, a clamp ring for clamping the sealing materials is arranged on the inner side of the sealing box, and a jacking device is arranged on the inner side of the clamp ring. Bolts penetrate through the box side plates, the sliding plate and the slide, nuts are screwed on the bolts, and compression springs positioned among the box side plates and the nuts are sleeved on the bolts. The conveyor tail sealing structure is quite ideal in use effect for the sodium carbonate industry, the cement industry and the chemical industry, solves the technical problem of long-term leakage at the tail of a conveyor, and meets the requirement on environmental protection.

Description

The conveyer tail sealing structure

Technical field

The utility model relates to all kinds of load transfer devices, particularly a kind of conveyer tail sealing structure of carrying for the requirement sealing of vertical-lift, all kinds of powderies of horizontal feed, graininess and lump material.

Background technology

At present, require all kinds of load transfer devices of sealing convey materials, such as bucket elevator, embedded scraper transporter etc.Because afterbody is provided with tension structure, there is an adjustment travel in afterbody, leaks the material problem with regard to existing between the sliding panel on the tailing axle and the box side, when tailing axle rotates, also has the side seal problem simultaneously.Especially when material thinner, and when having small positive pressure operation, above position material from leakage is more serious, and is more outstanding at some high temperature such as chemical industry, alkaline, cement, industry harmful, that chiseling property of mill is stronger especially, causes environmental pollution serious, the difficult problem that difficulty of governance is large.

The utility model content

The utility model provides a kind of and can thoroughly effect a radical cure the conveyer tail sealing structure that the conveyer afterbody leaks the material problem in order to solve weak point of the prior art.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the conveyer tail sealing structure, comprise box side, sliding panel, slideway and tailing axle, described sliding panel is provided with sealed letter, be filled with the leakproofing material that contacts with the tailing axle circumferential surface in the sealed letter, the sealed letter inboard is provided with the hold-down ring for the press seal material, and the hold-down ring inboard is provided with jack unit.

Be equipped with bolt between described box side, sliding panel and the slideway, be screwed with nut on the bolt, be arranged with the Compress Spring between box side and nut on the bolt.

Described jack unit comprises the set collar that is located on the tailing axle circumferential surface, set collar is connected with rotary packing ring by a guide pillar that is parallel to tailing axle, the hold-down ring medial surface is provided with the groove of one annular arrangement, the lateral surface of rotary packing ring be provided with extend in the groove and with projection or bulge loop that groove is rotationally connected, be provided with the top pressure spring that is enclosed within on the tailing axle between set collar lateral surface and the rotary packing ring medial surface.

Removably connect by axial bolt between described sealed letter and the hold-down ring, removably connect by radial screw between set collar and the tailing axle.

Adopt technique scheme, have following beneficial effect:

First, dynamic seal when solving the tailing axle rotation, prevent that material from axially spilling, employing has the again filled sealing of dynamic and static ring side seal, rotating ring is pressed on the stationary ring by the set collar compression top pressure spring generation axial thrust that is fixed on the tailing axle, rotating ring rotates with tailing axle, stationary ring then with sliding panel on the sealed letter that welds maintain static moving.Just produce end face labyrinth seal between the dynamic and static ring, stop material to enter between tailing axle and the compression gland, in order to strengthen sealing effectiveness, leakproofing material is housed also in the sealed letter, and compresses all the time with stationary ring, make side seal more perfect.

Second, material is leaked in the gap that solves between box side and the sliding panel, adopt the structure tension slideway of sheathed Compress Spring on the bolt, slideway abuts against the box side inboard with sliding panel, when sliding panel when sliding up and down, all the time be close to the box side inner surface, solve the leakage material problem between box side and the sliding panel.

The utility model is ideal for soda industry, cement industry, chemical industry result of use, has solved conveyer and has leaked the technical barrier of material problem in the afterbody long-term existence, has reached environmental demands.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the enlarged drawing at I place in the middle of Fig. 1;

Fig. 3 is the left view of Fig. 1.

The specific embodiment

Such as Fig. 1, Fig. 2 and shown in Figure 3, conveyer tail sealing structure of the present utility model, comprise box side 1, sliding panel 2, slideway 4 and tailing axle 13, sliding panel 2 is provided with sealed letter 5, be filled with the leakproofing material 12 that contacts with tailing axle 13 circumferential surfaces in the sealed letter 5, sealed letter 5 inboards are provided with the hold-down ring 6 for press seal material 12, and hold-down ring 6 inboards are provided with jack unit.

Jack unit comprises the set collar 8 that is located on tailing axle 13 circumferential surfaces, set collar 8 is connected with rotary packing ring 7 by a guide pillar 10 that is parallel to tailing axle 13, hold-down ring 6 medial surfaces are provided with the groove 14 of one annular arrangement, the lateral surface of rotary packing ring 7 be provided with extend in the groove 3 and with projection or bulge loop 15 that groove 3 is rotationally connected, be provided with the top pressure spring 11 that is enclosed within on the tailing axle 13 between set collar 8 lateral surfaces and rotary packing ring 7 medial surfaces.

Be equipped with bolt 3 between box side 1, sliding panel 2 and the slideway 4, be screwed with nut 16 on the bolt 3, be arranged with the Compress Spring 17 between box side 1 and nut 16 on the bolt 3.

Removably connect by axial bolt 18 between sealed letter 5 and the hold-down ring 6, removably connect by radial screw 9 between set collar 8 and the tailing axle 13.

When tailing axle 13 rotates, turn round together with set collar 8, top pressure spring 11, rotary packing ring 7 by guide pillar 10, the projection on the rotary packing ring 7 or bulge loop 15 rotate along groove 3.And with sliding panel 2 and sealed letter 5 relatively-stationary hold-down rings 6, and be designed with labyrinth seal and side seal between the rotary packing ring 7, here be unique passage that material outwards passes through axial leakage, as seen, very little from the possibility of leaking here, add by hold-down ring 6 and compressed leakproofing material 12, more reduced the possibility of material from leakage.

When sliding panel 2 slided up and down along with tailing axle 13, because the effect of Compress Spring 17, bolt 3 tension slideways 4 were adjacent on box side 1 sliding panel 2 all the time, have prevented that effectively material is from leaking between sliding panel 2 and the box side 1.
