Description
Technical field
The utility model relates to a kind of envelope, and a kind of specifically structural design by self realizes the knockdown axle envelope new structure that the slag stock pump of mechanical seal cooling liquid automatic cycle cooling is used.
Background technique
The slag stock pump is as a kind of fluid device of pumping the liquid that contains solid impurity, and its envelope is to stop pump housing active chamber to contain a kind of sealing configuration of the high pressure slurry of solid particle to external leakage.General shaft seal structure is the fabricated structure of sub-propeller and filler.
The built-up shaft seal structure of sub-propeller and filler generally need be connected the high-pressure shaft water shutoff, as shown in Figure 1, is made up of sub-propeller 2, Stuffing box 3, seal cage 4, filler 5, Gland 6, axle sleeve 7, high pressure shaft seal water pipe 8.Specifically be exactly: between the sub-propeller 2 and filler 5 of slag stock pump, feed the high-pressure shaft water shutoff, and pass through the turning effort of sub-propeller 2, the high pressure slurry in the active chamber is stoped the front end that seals the position at axle, to reduce the leakage at axle envelope place through high pressure shaft seal water pipe 8.Through the running of certain hour, the friction of axle sleeve 7 and filler 5 causes the wearing and tearing of filler, and leakage can increase the weight of, and therefore will often remove to compress filler 5 by Gland 6, and regularly filler 5 is changed.Fail in time to compress or change filler 5, the slurry that contains solid particle of leakage will enter the damage that causes bearing in the bearing.Therefore, the wearing and tearing replacing of the replacing of filler 5, axle sleeve 7 and device context are equipped with the cooling water source of high pressure, and it is very inconvenient to cause this axle to be enclosed in the equipment using process.The damage of bearings that leakage causes also influences the safe operation of complete machine.
The built-up shaft seal structure of sub-propeller that has and filler need not only to need grease up to the logical high-pressure shaft water shutoff in filler position, as shown in Figure 2, is made up of sub-propeller 2, Stuffing box 3, spacer ring 9, filler 5, Gland 6, axle sleeve 7, priming cup 10.Specifically be exactly: between filler, inject lubricating grease filler 5 is lubricated, to reduce the friction of filler 5 and axle sleeve 7.Though this structure need not be equipped with the high-pressure cooling water source, many defectives such as complete machine safe operation are revealed seriously, influenced to same frequent replacing filler 5 and axle sleeve 7, the axle envelope of existing.
The model utility content
In order to solve the problem that above-mentioned prior art exists, the utility model provides a kind of slag stock pump that has the self-circulation cold radiator cooler to seal with built-up shaft, the axle envelope realization nothing of slag stock pump is leaked, and equipment use scene need not to be equipped with the cooling source system.
Technical solutions of the utility model are: a kind of slag stock pump that has the self-circulation cold radiator cooler seals with built-up shaft, comprises sub-propeller, axle sleeve, it is characterized in that, adopts the Seal cage structure, is provided with self-loopa cooling case in the outside of Seal cage; The close encapsulation chamber is made up of decompression lid, sealed case and sealing axle sleeve, is filled with cooling liquid in the chamber, also is provided with mechanical seal in the chamber on the sealing axle sleeve; Self-loopa cooling case is provided with ascending tube and down tube, links to each other with the close encapsulation chamber respectively, and how much that observes cooling liquid for convenience can also be provided with transparent viewing window on cooler bin.
The beneficial effects of the utility model are: solved the shaft sealing leakage problem of slag stock pump, effectively improved the working life of mechanical seal, and device context need not to be equipped with the cooling source system, especially lack the area in water resources, product can not be subjected to using limitation.

Embodiment
In Fig. 3, a kind of slag stock pump that has the self-circulation cold radiator cooler seals with built-up shaft, comprises sub-propeller, axle sleeve, it is characterized in that, adopts the Seal cage structure, is provided with self-loopa cooling case in the outside of Seal cage.Mechanical seal 15 is installed in that decompression cover 11, in the close encapsulation chamber of O type circle 12, sealed case 13 and sealing axle sleeve 14 compositions, Seal cage is connected with self-loopa cooling case 16 and is full of cooling liquid (clean water or lubricant oil), to guarantee that mechanical seal 15 moves all the time in cooling liquid; The front end of mechanical seal 15 is provided with sub-propeller 2, decompression covers 11, the high pressure slurry that turning effort by sub-propeller 2 can effectively stop pump housing active chamber to contain solid particle enters into the mechanical seal position, improve the working environment of mechanical seal 15, improve the working life of mechanical seal 15; The self-loopa cooling case 16 that has transparent windows 19, cooling liquid down tube 17, cooling liquid ascending tube 18 is formed the self-circulation cold radiator cooler, cooling liquid down tube 17, the two ends of cooling liquid ascending tube 18 respectively with sealed case 13, self-loopa cooling case 16 is connected, in self-loopa cooling case 16, add the viewing position of inject cooling liquid (clean water or lubricant oil) to transparent window, when equipment operation, cooling liquid in the self-loopa cooling case 16 enters Seal cage through cooling liquid down tube 17, mechanical seal 15 is cooled off, turning effort by pump shaft 1, enter the also rotation thereupon of cooling liquid of Seal cage, after the effect that is subjected to sealed case 13 middle part baffle arrangements, be advanced into cooling liquid ascending tube 18 on the cooling liquid, like this, the cooling liquid of taking away the mechanical seal frictional heat is got back to the top of self-loopa cooling case 16 by cooling liquid ascending tube 18, flow through again cooling liquid down tube 17 of the relatively low cooling liquid of bottom temp replenishes to enter in the Seal cage mechanical seal 15 is cooled off, and going round and beginning again forms automatic cooling recirculation system.This structure has guaranteed that mechanical seal always works in the cooling liquid of low temperature, cleaning, and need not to be equipped with cooling system separately in device context.Therefore, this technology is applied to not only solve the shaft sealing leakage problem on the slag stock pump, has improved the working life of mechanical seal, and has saved cooling water resources, especially lacks the area in water resources, and product can not be subjected to using limitation.This built-up shaft envelope that has the self-circulation cold radiator cooler is applied on the slag stock pump product, is a kind of comparatively desirable axle envelope new technology.
