[0002] In mineral processing, chemical industry, coal, smelting, new energy and other industries, materials are often concentrated or graded (collectively referred to as solid-liquid separation). Commonly used equipment includes circular tank thickeners, inclined plate thickeners, inclined tubes and other equipment. Among them, the circular tank thickener requires a large area, and the inclined tube itself has poor structural strength and a short service life.

[0003] Inclined plate thickeners have advantages such as smaller footprint and greater strength than inclined tubes, making them more adaptable. The key to inclined plate thickeners lies in the inclined plate core, which is designed for different application areas and materials.

[0005] Therefore, in view of this, the existing structure is studied and improved, and an inclined plate core member of an inclined plate thickener is provided, in order to achieve the purpose of having more practical value. Summary of the Invention

[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0060] Example 1:

[0061] See also Figure 1 - Figure 5 A ramp plate core member of a ramp plate thickener comprises a ramp plate 1 and a ramp plate unit support strip 2, wherein the ramp plate 1 and the ramp plate unit support strip 2 are connected by a mortise and tenon joint, and the ramp plate unit support strip 2 supports the ramp plate 1 and forms a ramp plate support unit;

[0062] The inclined plate 1 is a flat plate structure made of modified high-polymer polypropylene. The inclined plate unit support strips 2 are a frame structure made of modified polyvinyl chloride. These strips consist of side strips 201 and center strips 202. The side strips 201 are located on both sides and the sides of the inclined plate 1, while the center strips 202 are located in the center of the inclined plate. The spacing between the inclined plate support units is 35 to 50 mm, and the overall inclination angle of the inclined plate support units ranges from 40° to 70°.

[0063] Example 2:

[0064] Based on the above embodiment 1, further description is given.

[0065] Specifically, the inclined plate 1 includes a base material, an auxiliary material and a modified filler, wherein:

[0066] The base material is polypropylene, and the weight content of polypropylene in the inclined plate 1 ranges from 50 to 60%;

[0067] The auxiliary material is talcum powder, and the weight content of talcum powder in the inclined plate 1 is in the range of 35% to 40%;

[0068] The modified filler is one or more of aramid fiber filler, silicon carbide filler, graphene oxide powder filler, and graphite powder filler. The weight content of the modified filler in the swash plate 1 is in the range of 5-15%.

[0069] By adjusting the ratio of the base material, auxiliary material and modified filler in the inclined plate 1, the strength and toughness of the inclined plate 1 are ensured, and at the same time, the inclined plate 1 has multiple excellent properties such as corrosion resistance, wear resistance and high temperature resistance.

[0070] Specifically, the performance of the inclined plate 1 was tested and its performance met the following technical indicators:

[0071] project Testing standards or conditions index unit Talc content GB / T 9345 35％～40％ ％ Inclined plate density GB / T 1033 ≤1.25 kg / l Inclined plate melt index GB / T 3682 1～4 g / 10min Inclined plate tensile strength GB / T 1040 ≥30 MPa Bending strength of inclined plate GB / T 9341 ≥45 MPa Inclined plate thermal deformation temperature GB / T 1634 ≥98 ℃ Unnotched impact strength of inclined plate GB / T 1043 ≥5 <![CDATA[KJ / m 2 ]]>

[0072] It is ensured that the talc powder in the auxiliary materials meets the requirements under various standards, thereby ensuring that the finally formed inclined plate 1 meets the required characteristics.

[0073] See Figure 3 、 Figure 4 Specifically, the dimensions and limit deviations of the inclined plate 1 are as follows:

[0074]

[0075] Specifically, the thickness of the burr edge of the inclined plate 1 is determined by the thickness of the plate, and whether the inclined plate 1 is qualified is determined based on the thickness of the burr edge. The corresponding standards for the thickness of the burr edge of the plate are as follows:

[0076] Plate thickness (mm) 2 3 4 5.5 6 Burr thickness (mm) ≤1.8 ≤2.7 ≤3.7 ≤5.2 ≤5.7

[0077] The surface of the inclined plate 1 is smooth and flat, and should be able to slide easily in the slot when assembled with the matching side strip structure 201;

[0078] Specifically, the side strip structure 201 has a specification of one of 50mm spacing side strips and 35mm spacing side strips;

[0079] There are also special side strips with 35 or 50mm spacing;

[0080] The specification of the middle spacer structure 202 is one of the following: 50mm spacing Japanese strips and 35mm spacing Japanese strips;

[0081] 50mm spacing Japanese strips are used in conjunction with 50mm spacing side strips, and 35mm spacing Japanese strips are used in conjunction with 35mm spacing side strips.

[0082] When there is a special need, special side strips are used to connect the two inclined plates, and side strips are used at both ends to widen the layout of the settlement unit.

[0083] Ensure the supporting effect of the inclined plate unit support strip 2 on the inclined plate.

[0084] See Figure 1 Specifically, an I-shaped tenon 2011 is fixedly installed on the top of the side strip structure 201.

[0085] The I-shaped tenon 2011 facilitates the connection between the side strip structure 201 and the inclined plate 1 .

[0086] See Figure 1 Specifically, an I-shaped socket 2012 is opened at the bottom end of the side strip structure 201, and the I-shaped tenons 2011 at adjacent positions are mortised with the I-shaped socket 2012.

[0087] Two adjacent side strip structures 201 can be connected into a whole through the snap-fit ​​relationship between the I-shaped tenon 2011 and the I-shaped socket 2012. In this way, the spacing value between the inclined plate 1 and the inner wall of the inclined plate thickener can be easily adjusted to an integer multiple of the length value of the side strip structure 201.

[0088] Example 3

[0089] Based on the above embodiment 2, further description is given.

[0090] The specifications and linear density requirements of the formed board are as follows:

[0091]

[0092] Example 4

[0093] Based on the above embodiment 1, further description is given.

[0094] The inclined plate unit support strip 2 is a modified polyvinyl chloride frame structure. The modified polyvinyl chloride formula includes three stages:

[0095] First, CPVC / PVC two-component modified formula;

[0096] Second, the CPVC / PVC / SMA ternary modified formula stage;

[0097] Third, pure CPVC one-component modified formula;

[0098] Although ordinary PVC has good acid and alkali resistance and is easy to be processed into special-shaped materials, its operating temperature is below 60°C, so it cannot be directly used to process into profiles. CPVC (content 63-69%) is a heat-resistant modified product with an operating temperature 30-40°C higher than PVC, and its mechanical properties reach or exceed PVC.

[0099] However, using it alone has the following problems:

[0100] First, the melt viscosity is high during processing, making molding difficult;

[0101] Second, the cost is high, the price is twice that of PVC, and it lacks competitiveness.

[0102] Therefore, it must be mixed with other polymers or used as a filler to reduce production costs while maintaining performance. The study used AS as a solubilizer, which increased the rigidity and heat resistance of the product, but reduced its toughness. Adding a certain amount of CPE, an impact-resistant agent, and appropriate amounts of CaCO3 and glass fiber simultaneously reduced costs and increased the material's bending resistance and heat resistance.

[0103] The research went through three phases:

[0104] In the first two phases of research, when PVC was added, the heat deformation temperature (HDT) of the material decreased; glass fiber can improve the heat resistance of the product, but it causes greater wear and tear on the equipment;

[0105] When calcium carbonate or talc is used as filler, bubbles appear during the blending and extrusion process.

[0106] In this study, the addition of styrene (S), maleic anhydride (MA), and graphite successively reduced air bubbles and increased heat distortion temperature (HDT). Graphite also reduced wear on equipment and extended service life. It can be added as a filler to the formula. A pure CPVC mono-modified formula was used. The parameters of the pure CPVC mono-modified formula are shown in the following table:

[0107]

[0108] The performance test indicators of CPVC mono-modified formula specimens are as follows:

[0109]

[0110]

[0111] In the formulation No. 2008 in the table, with the combination of CPVC and graphite, the heat deformation temperature (HDT) reaches 121°C. Due to the addition of MBS (methacrylate-butadiene-styrene copolymer, an impact modifier), the impact strength is improved, meeting the use requirements.

[0112] Working principle:

[0113] The inclined plate core member is composed of an inclined plate 1 and an inclined plate unit support strip 2 connected by mortise and tenon joints. The inclined plate unit support strip 2 is composed of a side strip structure 201 and a middle partition strip structure 202. When in use, select the side strip structure 201 and the middle partition strip structure 202 of corresponding specifications, determine the spacing between two adjacent inclined plates 1 according to the process requirements, and select side strip structures 201 and middle partition strip structures 202 of different specifications.

[0114] When the inclined plate chip is assembled, two adjacent side strip structures 201 can be connected into a whole through the snap-fit ​​relationship between the I-shaped tenon 2011 and the I-shaped socket 2012, thereby achieving stable support for the inclined plate 1.

[0115] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
