Detailed description of the invention

Embodiment one:

See Fig. 1, this utility model one is stained with pulp grinder, it includes slip bucket 3, rotating driving device 7, scraper plate 5 and insert 4, slip bucket 3 is rotatably mounted on support 6, rotating driving device 7 is installed in support 6, the clutch end of rotating driving device 7 is connected bottom slip bucket 3, and scraper plate 5 is installed in slip bucket 2 by pillar 2, and insert 4 is removably filled and is installed in slip bucket 3；Insert 4 includes body 41, fastening part, top 43 and side joint 42, it is provided with for accommodating the die cavity 44 waiting to be stained with the formwork of slurry operation on body 41, fastening part, top 43 is connected with body 41 one by side joint 42, and fastening part, top 43 is pressed on the bucket wall end face 31 of slip bucket 3 by alignment pin 1；The bucket wall top of slip bucket 3 is additionally provided with hold down gag 8, and the fastening part, top 43 of insert 4 is pressed on the bucket wall end face 31 of slip bucket 3 by hold down gag 8 further.

The die cavity 44 wherein arranged on insert body 41 is according to waiting that the geometry being stained with the formwork of slurry operation carries out adaptable configurations, and in the present embodiment, die cavity 44 is in-line, and is arranged in the top planes of insert body 41, as shown in Figure 2；

Seeing Fig. 3, the top end face 411 of insert body 41 is the inclined-plane having a down dip to insert body central, and top planes 411 is 1 °～3 ° with the angle α of horizontal plane；The outer wall side face 412 of insert body is that the tapering β of the conical surface is 1 °～3 ° to the insert body bottom portion center position tapered conical surface；When insert 4 is lifted out slurry level, the top planes 411 tilted, tapered outer wall side face 412 can be easy to slip and be back in slip bucket to realize the recycling of slurry, on the one hand can reduce the waste of slurry, on the other hand also can reduce the slip residual on insert surface.

Vertical groove 45 is offered on the sidewall of insert body 41, the bottom surface of insert body 41 is provided with and the bottom groove 46 of vertical groove 45 UNICOM, bottom groove 46, vertical groove 45 are respectively used to accommodate scraper plate 5, pillar 2, thus ensure that when formwork being stained with slurry operation insert 4 will not produce interference to the structure of scraper plate 5, pillar 2, and make after completing to be stained with slurry operation, insert 4 from slip bucket 3 in, remove taking-up after scraper plate 5, the normality of agitating function of pillar 2 function.

Insert 4 uses the stainless steel material of the mild alkaline conditions of resistance to PH7-9 under room temperature to make, and it is made up of any one in 1Cr13,1Cr17, austenitic stainless steel material, so that insert has good surface roughness, contribute to reducing further the slip residual on insert surface, and can effectively extend the service life of insert；And the surface roughness of insert is controlled in the range of RA0.8～1.6, it is possible to further ensure that the slip residual quantity on insert surface is little, thus increase the service life.

Embodiment two is with the difference of embodiment one, the die cavity 44 arranged on insert body 41 is for be formed by connecting by multiple typing chambeies are through, see Fig. 3, it includes the cross die cavity 44a being arranged at insert body 41 top planes, four the vertical die cavity 44b being set in parallel on insert body 41, and cross die cavity 44a and four vertical die cavity 44b is through.

When wait to be stained with the moulding surface structure of formwork of slurry operation complicated and in the case of causing the cavity structure also complexity of the corresponding structure on insert body 41, die cavity 44 is configured to multiple typing chamber and the plurality of typing chamber is configured to mutual UNICOM, to ensure that whole die cavity 44 can wait to be stained with the formwork of slurry operation and slip can sufficiently flow into whole die cavity 44, so that it is guaranteed that the full and uniform of formwork is stained with slurry by reliable containment.

nullUse this utility model be stained with slurry equipment formwork is stained with slurry operation time，In slip bucket 3, first configure slip，Then rotating driving device 7 is started，Slip bucket 3 is driven to rotate by rotating driving device 7，Slip in bucket is stirred by the scraper plate 5 being arranged in slip bucket 3 during slip bucket 3 rotates，Rotating driving device 7 is closed after slip stirs，And after slip bucket 3 stops the rotation, insert 4 is put into slip bucket 3，During insert 4 puts into slip bucket 3, slurry level constantly promotes，Final slip is stuffed entirely with in whole die cavity 44，The scraper plate 5 of slip bucket 3 and pillar 2 are then isolated and are contained in the bottom groove 46 of insert 4 and vertical groove 45 without being infiltrated by slip in the process，Recycling alignment pin 1、The sidewall end face of the end face fastening part of insert 4 with slip bucket 3 is locked thus is realized the insert 4 locking positioning with slip bucket 3 to prevent insert 4 from rotating in slip bucket by hold down gag 8，Then the formwork waiting to be stained with slurry operation being put into slip bucket 3 makes formwork complete to be stained with slurry at the die cavity 44 of insert 4，After being stained with slurry and completing, insert 4 is taken out from slip bucket 3 cleaning，Scraper plate 5 and pillar 2 in slip bucket 3 recover normal agitating function.

As a example by the formwork of the titanium alloy casting used by certain aero-engine below is stained with slurry operation, elaborate technical solutions of the utility model:

The titanium alloy casting that certain aero-engine uses, its formwork uses cross to water guidance tape, running channel board diameter 568mm, formwork height 453mm, the slip bucket diameter 720mm of selection, high 600mm, use yttrium colloidal sol preparation slurry solution, by calculating, in using traditional turning barrel scraper-type to be stained with pulp grinder slip to be made bucket, slip is totally submerged formwork, needs slip volume 138.5L, and liquid level reaches 479mm.

According to technical solutions of the utility model, according to the slip bucket size selected, the dimensional structure of formwork, Design and Machining manufactures insert 4, insert 4 uses stainless steel material to make, insert 4 uses the insert structure in embodiment two, by calculate homophase slip bucket dimensional conditions under, in slip bucket, configuration is such as the insert in embodiment two, and the slip that need to configure 45L can ensure that slip can be totally submerged formwork.

Use the slip bucket being equipped with insert 4 that formwork is stained with slurry, required slip volume falls sharply to 45L from the 138.5L using the barrel-shaped formula of traditional slurry, thus drastically increase the utilization rate of slip, for using the slip of the expensive binding agent configurations such as yttrium colloidal sol, Alumina gel or zirconium colloidal sol, manufacturing cost saves more than 70%.
