The steel scraper in the traditional planetary high-speed mixer is easy to wear and age during use due to the high hardness of the refractory material, resulting in a longer static mixing time of the mud, reduced production efficiency, partial aggregation of powder, uneven mixing of raw materials, and uneven distribution of indicators.

[0003] Therefore, how to provide a composite scraper for a planetary mixer is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0004] To this end, the purpose of the utility model is to propose a composite scraper for a planetary mixer to solve the problem that the existing steel scraper is easy to wear and age due to the high hardness of the refractory material, resulting in a longer static mixing time of the mud, reduced production efficiency, partial powder aggregation, uneven mixing of raw materials, and uneven distribution of indicators.

[0008] Furthermore, the scraper body has a double convex structure and a single convex structure arranged staggered therewith, and the blade surfaces of the double convex structure and the single convex structure are both covered with the boride-based metal ceramic block.

[0009] Furthermore, the boride-based metal ceramic block is bonded to the blade surface of the scraper body by epoxy resin glue.

[0010] Furthermore, the boride-based metal ceramic block adopts a rhombus structure.

[0011] Furthermore, the boride-based metal ceramic blocks are sequentially bonded to the blade surface according to the shape of the scraper body.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The existing steel scraper is easy to wear and age due to the high hardness of the refractory material, which leads to longer static mixing time of the mud material, reduced production efficiency, aggregation of some powder materials, uneven mixing of raw materials, and uneven distribution of indicators.

[0020] In view of this, the following explanation is given by taking the scraper of the mixer as an example: there are three scrapers in the mixer, two of which are double-convex structures and the other is a single-convex structure.

[0021] See attached Figure 1-3The scraper comprises: a scraper body 1, which is made of steel; a boride-based metal ceramic block 2, and a boride-based metal ceramic block 2 is connected to the blade surface of the scraper body 1.

[0022] The above scheme connects a boride-based metal ceramic block to the blade surface of the steel. The boride-based metal ceramic block has high hardness, high heat conductivity, and wear resistance, which significantly reduces the static mixing time of the mud material and improves production efficiency.

[0023] Advantageously, the scraper body 1 has a double protrusion structure 11 and a single protrusion structure, and the blade surfaces of the double protrusion structure 11 and the single protrusion structure are covered with the boride-based metal ceramic block 2. The boride-based metal ceramic block 2 is bonded to the blade surface of the scraper body 1 by epoxy resin glue.

[0024] More advantageously, the boride-based metal ceramic block 2 adopts a rhombus structure 21 .

[0025] In the embodiment of the utility model, the boride-based metal ceramic blocks 2 are sequentially bonded to the blade surface according to the shape of the scraper body.

[0026] In the above scheme, after the boride-based metal ceramic block 2 is bonded to the scraper body 1, it is dried at 140 degrees for 8 hours.

[0027] The manufacturing steps of the composite scraper of the utility model include:

[0028] Bonding rhombic boride-based metal ceramic blocks to two raised structures and a single raised structure on the blade surface of the scraper body, and using epoxy resin glue to bond the boride-based metal ceramic blocks to the raised scraper surface; drying the bonded scraper at 140 degrees for 8 hours to fully cure the adhesive;

[0029] Special steel (such as manganese 13 chromium 12) is used to make the scraper body.

[0030] A curing agent can be added to the glue, with the ratio of glue to curing agent being 1:1, and the boronized metal ceramic block can be bonded to the main body with a drying temperature of 140°C and a drying time of 8 hours to ensure a firm bonding effect.

[0031] The utility model manufactures the scraper body, bonds the boride-based metal ceramic block, and has the advantages of convenient installation, operation, wear resistance, high efficiency, stable mud effect, and controllable process. The number of mixing materials for ordinary scrapers is about 600, and the number of mixing materials for this new scraper is about 2000, as shown in the following table:

[0032] Serial number date Device Number Material Mixing quantity / piece 1 May 6 Magnesium Carbon 2000 2 June 6 Magnesium Carbon 2003 3 July 7 Magnesium Carbon 1995 4 August 8 Magnesium Carbon 1996 5 September 9 Magnesium Carbon 1998 6 October 6 Magnesium Carbon 1995 7 November 7 Magnesium Carbon 1994 8 December 8 Magnesium Carbon 2005

[0033] The uniformity of the mud mixture, the bulk density of ordinary scraper mud is 1.7g / cm 3The bulk density of composite scraper mud is 1.9g / cm 3 .

[0034] Among them, the amount of mud shows that after the improvement of this application, the scraper utilization efficiency has increased by 3 times, and the stacking density shows that the mud is mixed more evenly and densely.
