Description

Technical Field

[0001] This utility model belongs to the field of pearlescent pigment processing technology, specifically relating to a sieving device for silver-white pearlescent pigment used in building exterior walls. Background Technology

[0002] Silver-white pearlescent pigments for building exteriors are a specific application of silver pearlescent pigments, possessing a unique pearlescent effect. It is a result of the combination of materials science and optical engineering, precisely controlling coating thickness and particle arrangement to coordinate interference colors and pearlescent reflection, thereby achieving a dynamic visual effect. It is widely used in the architectural field, where aesthetics and functionality are pursued. Silver-white pearlescent pigments can give building exteriors a unique silver-white pearlescent appearance, making them stand out among other buildings, increasing their visual appeal and artistic value, and can be used to create modern, fashionable, or luxurious architectural styles. Furthermore, it can play a protective role for building exteriors to a certain extent. It can reflect some ultraviolet rays and heat, reducing UV damage to the wall, lowering the wall temperature, delaying the aging and damage of wall materials, and extending the service life of the building exterior.

[0003] Pearl pigments, after surface treatment and drying, are prone to forming agglomerates. These agglomerates not only affect the product's appearance and application properties but also hinder the application of the pearl pigments themselves. During production, sieving is necessary based on the particle size of different pearl pigments to obtain a product with clear, unagglomerated particles. Pearl pigments themselves have a multi-layered coating structure and a pearly luster; however, common vibrating screens are prone to clogging due to these agglomerates, resulting in low sieving efficiency. Further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a sieving device for silver-white pearlescent pigments used in building exterior walls, in order to solve the problem that particle agglomerates easily clog the screen during sieving in existing sieving devices, resulting in low sieving efficiency.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A screening device for silver-white pearlescent pigment used in building exterior walls includes a housing, a pretreatment component, and an air classification component. The housing has an inlet at one top end and a notch at the other bottom end. The pretreatment component includes a mounting shell installed on the top of the housing, located below the inlet. A discharge plate and a vertical channel are provided inside the mounting shell. A dispersing component is installed inside the mounting shell, extending into the vertical channel to disperse the material falling from the discharge plate. The air classification component includes an air supply unit. The unit includes a material receiving channel; the air supply component is installed in the middle of the housing, and the air outlet of the air supply component is close to the side of the mounting shell; at least two material receiving channels are arranged at the bottom of the housing, and the top opening of each material receiving channel has a different horizontal projection distance from the vertical channel; the air outlet blows the material falling from the vertical channel into the corresponding material receiving channel according to different particle sizes; the bottom end of the material receiving channel is horizontally connected to a grading pipe assembly, which extends from the notch for outputting the air-separated material.

[0007] The material processed in this application is obtained through coating, filtration, and drying processes during the preparation of silver-white pearlescent pigment for building exterior walls. The material enters through the feed inlet from the feed plate to the vertical channel, where it is dispersed by the dispersing component and falls. The air outlet of the air supply component blows air horizontally, causing materials of different particle sizes to be blown by the same wind force and given a horizontal force. Combined with the material's own gravity, they move in a curved path, and materials of different particle sizes fall into different receiving channels, thus achieving material sieving. The material is then graded and output through a grading pipe assembly to obtain the sieved silver-white pearlescent pigment.

[0008] Furthermore, the feeding plate is inclinedly installed inside the mounting housing, with the top of the feeding plate located on one side of the mounting housing, and a passage opening provided on the other side of the mounting housing. A baffle plate is installed outside the passage opening to form the vertical channel; the bottom end of the feeding plate overlaps the passage opening; the dispersing component includes a pair of motors installed inside the mounting housing, and a dispersing blade is installed at the output end of each motor, with the dispersing blade extending inclined downward to the vertical channel.

[0009] Furthermore, the top end of the feeding plate is rotatably mounted on the side wall of the mounting shell via a hinge shaft; a heating element and a vibrator are mounted on the bottom wall of the feeding plate.

[0010] Furthermore, the graded pipeline assembly includes a discharge pipe and a connector, wherein the discharge pipe is connected to the bottom end of the receiving channel through the connector; wherein the number of discharge pipes, connectors, and receiving channels is the same.

[0011] Furthermore, the screening device also includes a screening component, which is installed on the other side of the top of the housing; the grading pipeline assembly also includes a circulation pipe and a return shell, which is installed on the outer wall of the other side of the housing, and connects a portion of the discharge pipe to the return shell through the circulation pipe, for conveying a portion of the material in the discharge pipe to the screening component through the circulation pipe and the return shell.

[0012] Among them, the screening component can perform more refined re-screening of the air-separated materials, thereby ensuring the consistency of particle size of materials of various grades and specifications and improving the quality of the final product.

[0013] Furthermore, the screening component includes a mounting rod and filter plates, with at least two filter plates obliquely mounted below the top wall of the housing via the mounting rod; the bottom end of each filter plate extends beyond the air outlet by a certain distance; and the filter holes of each filter plate have different diameters.

[0014] Furthermore, a waste trough is installed at the bottom end of the filter plate near the top wall of the housing; and / or, a bottom cavity is provided on the bottom side of the filter plate near the air supply component for receiving and outputting the material filtered by the filter plate.

[0015] The utility model adopting the above technical solution has the following advantages:

[0016] In this application, the material is dispersed by a pretreatment component, and then separated into various specifications by an air separation component. During screening, the material enters from the feed inlet from the feed plate to the vertical channel, where it is dispersed by the dispersing component and falls down. The air outlet of the air supply component blows air horizontally, and materials of different particle sizes are blown by the same air force to move in a curved motion. Materials of different particle sizes will fall into different receiving channels, thus achieving screening of the material. Then, the material is graded and output through a grading pipe component to obtain the screened silver-white pearlescent pigment. It can also cooperate with the screening component to improve the uniformity of screening and has high practicality. Attached Figure Description

Detailed Implementation

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, a sieving device for silver-white pearlescent pigment for building exterior walls according to an embodiment of the present invention includes a box body 100, a pretreatment component 300, and an air separation component 400. A feed inlet 103 is provided at one end of the top of the box body 100, and a notch 105 is provided at the other end of the bottom of the box body 100. The side plate 106 of the box body 100 is located above the notch 105. An inspection port is provided on the front side of the box body 100, and a front cover plate 101 is installed on the inspection port by screws. The top of the box body 100 is open, and a top cover 102 is installed on the opening to form the top wall of the box body 100. A feed inlet 103 and a mounting hole 104 are machined on the top cover 102. A plurality of through holes are machined on the back plate 107 of the box body 100. The pretreatment component 300 includes a mounting shell 304 installed on the top of the housing 100, located below the feed inlet 103. The mounting shell 304 contains a discharge plate 301 and a vertical channel 302. A dispersing element 303 is installed within the mounting shell 304, extending into the vertical channel 302 to disperse the material falling from the discharge plate 301, eliminating any potential particle agglomerates in the material. The air separation component 400 includes an air supply component and a receiving channel. The air supply component can be a bellows, which is cantilevered and installed in the middle of the housing 100. The bellows' air inlet penetrates a corresponding through hole on the back plate 107, forming an air inlet 108 for connection to an industrial compressed air pipeline or air pump. The bellows' air outlet 401 is located near the mounting shell 304. The pressure, rate, and flow rate during pumping can be adjusted using an air pump or industrial compressed air pipeline. The four receiving channels are the first receiving channel 405, the second receiving channel 404, the third receiving channel 403, and the fourth receiving channel 402, which are arranged at the bottom of the box 100. The top openings of each receiving channel (i.e., the first receiving channel 405, the second receiving channel 404, the third receiving channel 403, and the fourth receiving channel 402) are at different horizontal projection distances from the vertical channel 302. The air outlet 401 blows the material falling from the vertical channel 302 into the corresponding receiving channel according to different particle sizes. The bottom of the receiving channel is horizontally connected to a grading pipe assembly 200, which extends from the notch 105 and is used to output the air-separated material.

[0029] For example, the dispersing component 303 includes a motor consisting of a mover 3032 and a stator 3031, and a dispersing blade 3033 connected to a mounting strip mounted on the side of the mover 3032. The dispersing blade 3033 can be a blade used in conventional cutting shears, which disperses the material based on a shearing action.

[0030] In fact, the number of receiving channels can also be set to three according to the material grading requirements, namely the first receiving channel 405, the second receiving channel 404, and the third receiving channel 403.

[0031] For example, the feeding plate 301 is installed obliquely inside the mounting housing 304, the top of the feeding plate 301 is located on the left side of the mounting housing 304, and a passage is opened on the other side of the mounting housing 304. A baffle plate 306 is installed on the outside of the passage to form a vertical channel 302; the bottom end of the feeding plate 301 overlaps the passage; and the corresponding dispersing blade 3033 extends obliquely downward to the vertical channel 302.

[0032] In practice, the top of the feeding plate 301 is rotatably mounted on the side wall of the mounting housing 304 via a hinge shaft 3011; a heating element and a vibrator 307 are mounted on the bottom wall of the feeding plate 301; the heating element can be an electric heating plate 305, whose power supply line is connected to a battery or an external power source; some of the through holes corresponding to the mounting housing 304 can be used as second wiring ports 112 for wiring. Some of the through holes also serve as first wiring ports 111 for the motor wiring. The vibration frequency of the vibrator 307 can be adjusted as needed.

[0033] In this embodiment, the graded pipeline assembly 200 includes a discharge pipe and a connector, wherein the discharge pipe is connected to the bottom end of the receiving channel through the connector; wherein the number of discharge pipes, connectors, and receiving channels is the same.

[0034] In practice, when there are four receiving channels, namely, a first receiving channel 405, a second receiving channel 404, a third receiving channel 403, and a fourth receiving channel 402, the corresponding discharge pipes are: a first discharge pipe 201, a second discharge pipe 202, a third discharge pipe 203, and a fourth discharge pipe 204. The connector is a square tube with one end larger than the other, and the smaller end of the square tube has a circular port that connects to the discharge pipe. These connectors are: a first connector 406, a second connector 407, a third connector 408, and a fourth connector 409. In practice, during installation, the larger ends of the first connector 406, the second connector 407, the third connector 408, and the fourth connector 409 can be installed on the connector frame 410 first, and then the connector frame 410 can be installed at the bottom of the receiving channel.

[0035] The outlet ends of the first discharge pipe 201, the second discharge pipe 202, and the third discharge pipe 203 can receive collection buckets to collect the corresponding materials after grading and screening, thereby obtaining materials of different particle size grades.

[0036] In this embodiment, the screening device further includes a screening component 500, which is installed on the other side of the top of the housing 100; the grading pipeline assembly 200 also includes a circulation pipe and a return shell 211, which is installed on the outer wall of the other side of the housing 100. The circulation pipe connects part of the discharge pipe to the return shell 211, and is used to transport part of the material in the discharge pipe to the screening component 500 through the circulation pipe and the return shell 211.

[0037] For example, the screening component 500 includes a mounting rod 501 and filter plates; three filter plates are installed at an angle below the top wall of the housing 100 via the mounting rod 501; the bottom of the filter plates extends beyond the air outlet 401 by a certain distance; and the filter holes of each filter plate have different diameters.

[0038] During installation, the distance by which the bottom of the filter plate extends beyond the air outlet 401 can be flexibly adjusted as needed. The three filter plates are a primary filter plate 502, a secondary filter plate 503, and a high-grade filter plate 504, with progressively smaller pore diameters to achieve graded screening. The mounting rod 501 has four mounting holes 104 on the top cover 102.

[0039] In fact, the materials output from the outlets of the first discharge pipe 201 and the second discharge pipe 202 are usable. However, the materials output from the outlets of the third discharge pipe 203 and the fourth discharge pipe 204 exhibit significant differences in particle size consistency, requiring further filtration and air separation. Therefore, they can be circulated through a recirculation pipe and then screened using the screening component 500.

[0040] For example, the return material shell 211 is a hollow shell with a partition in the middle; the return material shell 211 has a connection port at the right end near the filter plate, which connects to the gap between adjacent filter plates, and is used to transport the material that is transported to the return material shell 211 through the circulation pipe and the return material pipe to each filter plate.

[0041] When there are four discharge pipes, there can be three circulation pipes, namely the first circulation pipe 205, the second circulation pipe 206, and the third circulation pipe 207; correspondingly, the return material shell 211 is connected through the first return material pipe 208, the second return material pipe 209, and the third return material pipe 210, respectively.

[0042] In fact, the number of discharge pipes, connectors, and circulation pipes in this embodiment can be flexibly adjusted as needed.

[0043] For example, a waste trough 506 is installed at the bottom of the filter plate near the top wall of the housing 100, and a waste outlet 110 is provided on the back of the waste trough 506. A bottom cavity 505 is provided on the bottom side of the filter plate near the air supply component for receiving and outputting the material filtered by the advanced filter plate 504.

[0044] Among them, such as Figure 2 , Figure 5 As shown, the discharge port of the first discharge pipe 201 is configured as the first discharge interface 212, which is used to connect to the collection bucket. Similarly, the discharge port of the second discharge pipe 202 is configured as the second discharge interface 214; and the discharge port of the third discharge pipe 203 is configured as the third discharge interface 213. A fourth discharge interface 109 is provided on the back wall of the bottom cavity 505 for outputting materials inside the bottom cavity 505.

[0045] This embodiment provides a sieving device for silver-white pearlescent pigment used in building exterior walls. The material enters through the feed inlet 103 from the discharge plate 301 to the vertical channel 302, where it is dispersed by the dispersing component 303 and falls down. The air outlet 401 of the air supply component blows air in a horizontal direction, and materials of different particle sizes are blown by the same wind force to move in a curved motion. Materials of different particle sizes will fall into different receiving channels, thus achieving sieving of the material. Then, it is graded and output through the grading pipe assembly 200 to obtain the sieved silver-white pearlescent pigment. It can also cooperate with the screening component 500 to improve the uniformity of sieving and has high practicality.

[0046] The foregoing has provided a detailed description of a sieving device for silver-white pearlescent pigment used in building exterior walls, as provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
