Description

A kind of rotary vacuum dryer

Technical field

The utility model relates to a kind of drying equipment, relates to the rotary vacuum dryer that in a kind of pigment manufacturing process material is dehydrated specifically.

Background technology

In pigment manufacturing process, need to reach pigment filter cake more than 70% to water content and put into helicoid vacuum drier and carry out drying and dehydrating through press filtration.Existing rotary vacuum dryer, its primary structure are a biconial revolving drum that is rotatably connected on double bracket, are vacuum state in the revolving drum, and have interlayer on the barrel of revolving drum.Motor is in transmission connection through chain and the rotating shaft that is fixed on the revolving drum; Be rotated through the moving driving rotational tube of motor; Meanwhile, feed heating agent, make the pigment filter cake heat absorption evaporation in the revolving drum through interlayer to revolving drum; Take steam away by vavuum pump again, thereby accomplish dehydrating pigment filter cake.Usually reach 2.5 tons owing to put into the material of revolving drum, in the process of dry materials, its state is sticky by rare change; Sticky material is adsorbed on the revolving drum inwall easily, when revolving drum in rotary course, the material of absorption can fall under the gravity effect; Whole drying machine fuselage there is individual impulsive force; In the process of impacting, the chain that is connected in motor and the rotating shaft has born most impulsive force, makes the service life of chain extremely short; Have a strong impact on normally carrying out of producing, also caused the raising of production cost simultaneously.

The utility model content

For overcoming above-mentioned defective, the utility model aims to provide in use a kind of, and the impact that material falls to causing in the revolving drum can not cause chain fracture or excesssive gap, makes the chain rotary vacuum dryer of operate as normal for a long time.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of rotary vacuum dryer, comprise support, driving machine, gearbox and biconial revolving drum, and the cylindrical shell tympanic part of said revolving drum is connected with an air inlet pipe and an escape pipe; Said into and out of tracheae on the same axis and be positioned on the relative position of cylindrical shell tympanic part; Saidly be connected the top of support through bearing block, be arranged with a sprocket wheel on said air inlet pipe or the escape pipe, be arranged with driving chain between said sprocket wheel and the gearbox into and out of tracheae; Be fixed with a tensioning apparatus on the said support, the regulating wheel on the said tensioning apparatus is stretched on the driving chain.

Said tensioning apparatus comprises a fixed block and is fixed on the sleeve on the fixed block, slidably is connected with a telescopic shaft in the said sleeve, is arranged with a compression spring on the said telescopic shaft, the top of the said telescopic shaft regulating wheel that has been rotatably connected.

Be fixed with two sleeves on the said fixed block, slidably be connected with a telescopic shaft in each sleeve, be arranged with a compression spring on the said telescopic shaft, said regulating wheel is rotatably connected between the top of two telescopic shafts, and said regulating wheel is a duplex chain wheel.

Adopted the rotary vacuum dryer of the utility model; Owing to be provided with tensioning apparatus, in the rotary vacuum dryer course of work, through tensioning apparatus driving chain made and be in tensioning state eventually; And be able to decompose gentle washing out through the impulsive force of compression spring handle fuselage; Make driving chain can not rupture or lost efficacy, thereby production can be carried out continuously, and the cost of having avoided the frequent change driving chain to be caused rises because of frequently receiving impacting.

Description of drawings

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

Fig. 2 is a kind of tensioning apparatus example structure sketch map of the utility model.

Among the figure: the 1-support, the 2-driving machine, the 3-gearbox, the 4-revolving drum, the 6-bearing block, 7-cylindrical shell tympanic part, the 9-sprocket wheel, the 10-driving chain, the 11-tensioning apparatus, the 12-regulating wheel, the 13-fixed block, the 14-sleeve, the 15-telescopic shaft, 16-compresses spring, 17-duplex chain wheel.

The specific embodiment

As shown in Figure 1, the utility model discloses a kind of rotary vacuum dryer, comprise support 1, driving machine 2, gearbox 3 and biconial revolving drum 4; The cylindrical shell tympanic part 7 of said revolving drum 4 is connected with an air inlet pipe and an escape pipe, said into and out of tracheae on the same axis and be positioned on the relative position of cylindrical shell tympanic part 7 the said top that is connected support 1 into and out of tracheae through bearing block 6; Be arranged with a sprocket wheel 9 on said air inlet pipe or the escape pipe, be arranged with driving chain 10 between said sprocket wheel 9 and the gearbox 3, when specifically working; Put into revolving drum 4 to the material of required drying, open driving machine 2, through gearbox 3-driving chain 10-sprocket wheel 9-advance manage or a series of transmissions of escape pipe; Driving rotational tube 4 is rotated, and meanwhile, feeds the steam as heating agent through air inlet pipe; Steam heats the material in the revolving drum 4 when flowing through the interlayer of revolving drum 4 walls, makes moisture contained in the material receive thermal evaporation; And pass through escape pipe to the water vapour of evaporation and discharge; Through the regular hour, all evaporate moisture contained in the material, thus the process that dehydrates of completion material.

The innovative point of the utility model mainly is to be fixed with a tensioning apparatus 11 on the said support 1, and the regulating wheel 12 on the said tensioning apparatus 11 is stretched on the driving chain 10.Driving chain 10 tensionings, make driving chain 10 be in tensioning state in the course of the work all the time through regulating wheel 12, avoided driving chain 10 to receive the pulsed impact because of crossing pine.

Common said tensioning apparatus 11 comprises a fixed block 13 and is fixed on the sleeve 14 on the fixed block 13; Slidably be connected with a telescopic shaft 15 in the said sleeve 14; Be arranged with a compression spring 16 on the said telescopic shaft 15, the top of said telescopic shaft 15 regulating wheel 12 that has been rotatably connected.Said telescopic shaft 15 outwards ejects under the effect of compression spring 16; And regulating wheel 12 receives the roof pressure of driving chain 10; Telescopic shaft 15 is in poised state, and the impulsive force that when the material in the revolving drum 4 is falling, is producing is delivered to 10 last times of driving chain, and driving chain 10 passes to regulating wheel 12 to this impulsive force; Regulating wheel 12 drives telescopic shaft 15 in the process that sleeve 14 directions move, and compression spring 16 decomposes this impulsive force to be laid down.

Because driving chain 10 is double-stranded bar usually; For this reason, as shown in Figure 2, be fixed with two sleeves 14 on the said fixed block 13; Slidably be connected with a telescopic shaft 15 in each sleeve 14; Be arranged with a compression spring 16 on the said telescopic shaft 15, said regulating wheel 12 is rotatably connected between the top of two telescopic shafts 15, and said regulating wheel 12 is a duplex chain wheel 17.Said duplex chain wheel 17 is complementary with the driving chain 10 that adopts double-stranded bar structure.
