Abstract

The utility model provides a horizontal stirring sand muller, which is mainly composed of a machine body, a plurality of stirring cages uniformly distributed in the machine body, etc. Directions of action of the adjacent stirring cages are opposite in the utility model, the acting force among the stirring cages is mutually infiltrated, so molding sand can be rapidly and effectively made in a mixing way by the utility model.

Description

The horizontal cage puddle mixer that stirs

The utility model relates to a kind of puddle mixer, especially refers to can be used for mixing in the Foundry Production puddle mixer of system clay tide mould sand.

Existing sand blender can be divided into muller formula and rotator type two big classes, all adopts vertical structure, and ubiquity if mulling efficient is higher, and the mulling quality is good, but the device structure complexity, reliability is low, and maintainability is poor.And structure is simpler, the reliability height, and the puddle mixer that maintainability is good, it is low just to exist mulling efficient, the ropy shortcoming of mulling.

The purpose of this utility model is to overcome the deficiency of prior art for this reason, and a kind of not only mulling efficient height is provided, and the mulling quality is good, and productivity ratio is big, and simple in structure, and the reliability height is maintained puddle mixer easily.

The technical scheme that realizes the utility model purpose is a kind of horizontal cage puddle mixer that stirs, at least comprise that end seat and the many covers (being generally four or six covers) that are installed on the end seat stir cage, stirring the cage two ends is installed on two end seats by bearing, the end seat links to each other with lower house and access door by upper shell again, its feature part is to stir cage to form by stirring cage axle and blade, have on the cage axle with the equally distributed many group blades in identical gap stirring, every group of blade is evenly distributed with the polylith blade on circumference, being fixed on the blade that stirs on the cage axle all with axially has angle, and adjacent two working faces that stir the cage blade are towards on the contrary, and adjacent two stir cage and all have partial blade to stretch into the other side zone mutually.

And body adopts horizontal type structure, and mulling mechanism stirs cage by many covers and forms, and stirring cage is regular polygon and is symmetrically distributed in the cylindrical shape body, have charge door and scavenge port on upper shell, shedding mechanism is installed on lower house, access door is positioned at the body both sides.

And every cover stirs cage all the independent transmission mechanism of a cover, and the transmission mechanism that stirs cage is made of motor and decelerator, and connects with an end that stirs cage by the limited torque shaft coupling, and all stir the transmission mechanism mean allocation of cage on two end seats.

As shown from the above technical solution, the horizontal cage puddle mixer that stirs that the utility model provides, mulling mechanism adopts many covers (being generally four or six covers) to stir cage, when stirring cage and under the drive of transmission mechanism, rotating in the same way, blade will be positioned at the sand that stirs the cage below and take the top to, sand with the top takes the below to simultaneously, and big sand is rolled into a ball crowded broken.The blade that tilts also makes sand produce motion on the horizontal direction, and adjacent two to stir the sand flow horizontal movement direction that cage produces just opposite, makes two strands of sand flows produce strong stranding stone roller effects.The blade sphere of action of stirring cage is big, the dead angle is few, account for 90% of whole sand amount, all be full of molding sand in the body, one time feeding quantity is big, and it is little to take up room, compact conformation, thereby realized mulling efficient height, the mulling quality is good, the purpose that productivity ratio is big, puddle mixer adopts horizontal type structure, the transmission mechanism that stirs cage is installed on the end seat outside of body, and every cover stirs cage all independent transmission mechanism, and access door is positioned at the body both sides, outside puddle mixer, just can overhaul puddle mixer inside, thereby realized simple in structure, reliability height, purpose easy to maintenance.

Below with reference to accompanying drawing the utility model is further described.

Accompanying drawing 1 is a cutaway view of the present utility model.Accompanying drawing 2 is the left view of Fig. 1.

Accompanying drawing is the structural representation that stirs cage in the utility model.Accompanying drawing 3 is the left view of Fig. 4.

By shown in Figure 1, the utility model provides horizontal stir the cage puddle mixer mainly by upper shell 1, end seat 2, transmission mechanism 3, stir seven parts such as cage 4, access door 5, lower house 6, shedding mechanism 7 and constitute.As can be seen from Figure 2, stir cage 4 mainly by stirring cage axle 8 and blade 9 is formed.

In by upper shell 1, lower house 6 and end seat 2 cylindrical enclosure bodies that constitute, be regular polygon and be symmetrically distributed with how cover stirs cage 4, stirring cage 4 two ends is installed on two end seats 2 by bearing, wherein an end links to each other with transmission mechanism 3 by the limited torque shaft coupling, every cover stirs cage 4 all the independent transmission mechanism 3 of a cover, all stir transmission mechanism 3 mean allocation of cage 4 on two end seats 2, and the transmission mechanism 3 that stirs cage 4 mainly is made of motor and decelerator.Be evenly distributed with many group blades on the main shaft 8 that stirs cage 4, every group of blade comprises some individual blades 9 again, and is radial being uniformly distributed in diametrically and stirs on the cage axle 8.The two adjacent blades 9 that stir cage 4 are staggered in the axial direction in twos, make adjacent two rotating ranges that stir the blade 9 of cage 4 overlap the zone.The acting surface of blade 9 with stir cage axle 8 axis and be an angle, and two adjacent stir cage 4 blades 9 towards just opposite, when making adjacent two to stir cage 4 and rotate in the same way, produce two strands of sand flows that the direction of motion is just opposite.

Charge door and shedding mechanism 7 lay respectively at upper shell 1, and the middle part of lower house 6 helps rapid loading and discharging.Access door 5 is positioned at the body both sides, and enough big, convenient maintenance puddle mixer inside.

Close when shedding mechanism 7, stir cage 4 rotation after, can in body, add old sand by gallery ports, add other auxiliary material simultaneously, because all cages 4 that stir are all done along the rotation of (or contrary) hour hands, blade 9 will be positioned at the sand that stirs cage 4 belows and take top to, and the sand of top has taken the below to.And blade 9 also makes the motion on the sand generation horizontal direction.So in general, sand is round the body motion of spinning, the sand that contacts with inwall has played the cleaning effect, can prevent effectively that molding sand from sticking on the inwall.

In addition, some sand moves in a circle around stirring cage 4, since blade 9 with stir cage axle 8 center lines and have angle, thereby, blade 9 can also promote sand and do the horizontal cross motion, and adjacent two blade 9 acting surfaces that stir cage 4 are towards opposite (the first from left right side), make that the two sand transverse movement directions of stirring around the cage 4 are just opposite, and the speed official post sand that two strands of sand flows cause is subjected to rubbing with the hands the stone roller effect.In adjacent two overlapping regions of stirring cage 4, the linear velocity direction of blade 9 is opposite, makes that entering this regional sand is subjected to strong squeezing action, rubs stone roller effect and shear action with the hands, and rubs with the hands big sand group broken.

This horizontal cage puddle mixer that stirs adopts brand-new mulling mechanism, and the sphere of action of its blade 9 is big, and the dead angle is few, does not need ventilation and dust removal, have mulling efficient height, capacity is big, and the mulling quality is good, the characteristics of Cast sand aeration, and simple in structure, reliable operation, for ease of maintenaince, floor space is little.
