Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for raw materials used in the manufacture of white marble sand. Background Technology

[0002] With the development of the times, people are using various new materials more and more widely, and white marble sand is an important component of it. When mixed with other materials, it can effectively improve the mechanical stability and fire resistance of the finished product, and is therefore widely favored by people. In the process of its production, a sieving device is required for screening.

[0003] To address this, patent CN206276614U discloses a screening device, particularly an inclined raw material screening device for use in a spinning production line. It includes a screen frame containing a screen mesh, several vibrating motors, a material collection hopper at the bottom of the screen mesh, a raw material inlet at the top of the screen frame, and an impurity outlet at the bottom of the screen frame. The screen frame is inclined at a 37-degree angle. This inclined raw material screening device has a compact structure, reduces production costs, improves production stability, and enhances product quality.

[0004] However, it is designed with a separate motor to vibrate the screen during use, thereby increasing the screening effect, which will result in some energy waste. In addition, it is not convenient to maintain and clean the screen during use, thus making it somewhat limited in use. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material screening device for manufacturing white marble sand, so as to solve the defects of existing raw material screening devices for manufacturing white marble sand that are not convenient for saving energy and disassembly and maintenance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a raw material screening device for manufacturing white marble sand, comprising a main body and a support column;

[0007] The bottom end of the main body is uniformly fixed with support columns, and a feed port is opened on one side of the top end of the main body;

[0008] A metering structure is installed on one side of the feed inlet, and a waste discharge port is opened on one side of the bottom of the main body;

[0009] The main body has uniformly spaced limiting grooves inside, and each limiting groove is equipped with a sieve plate. A maintenance structure is provided on the outer wall of the main body on one side of the limiting groove.

[0010] Preferably, the metering structure includes a drive motor, a metering shaft, a metering plate, a transmission belt, an output shaft, and a cam. The drive motor is installed on one side of the feed inlet, and a metering shaft is provided on one side of the drive motor. Metering plates are evenly arranged on the outer wall of the metering shaft. A transmission belt is provided on the side of the metering shaft near the drive motor. Output shafts are evenly arranged on the inner wall of the transmission belt. A cam is fixed on one side of each output shaft.

[0011] Preferably, the metering shaft extends into the interior of the feed inlet, and the metering plates are evenly distributed on the outer wall of the metering shaft.

[0012] Preferably, the output shafts are symmetrically distributed on the inner wall of the transmission belt, and one side of the transmission belt extends into the interior of the main body.

[0013] Preferably, the limiting grooves are symmetrically distributed on the main body, and the top of the cam abuts against the bottom of the sieve plate.

[0014] Preferably, the maintenance structure includes a discharge port, an internal groove, a baffle, and a return spring. The discharge port is evenly distributed on the outer wall of the main body on one side of the limiting groove. An internal groove is provided on both sides of the discharge port. A baffle is provided inside the internal groove. A return spring is fixed on one side of each baffle.

[0015] Preferably, the built-in grooves are symmetrically distributed inside the main body on both sides of the discharge port, and the side of the reset spring away from the baffle is fixedly connected to one side inside the built-in groove.

[0016] The advantages of the raw material screening device for manufacturing white marble sand provided by this utility model are as follows:

[0017] By setting up a quantitative structure, starting the drive motor causes the quantitative shaft to drive the quantitative plate to rotate inside the feed inlet, thereby making the device fill the material evenly. A transmission belt is set on the outer wall of the quantitative shaft, which drives the output shaft to rotate synchronously. The top of the cam on one side of the output shaft abuts against the screen plate, which makes it easy for the screen plate to vibrate inside the limiting groove during rotation, thereby achieving the purpose of facilitating uniform material feeding and increasing the filtration and screening effect.

[0018] By incorporating a maintenance structure, the screen plate is positioned within the limiting groove to screen and remove impurities from the raw materials. This design prevents the screen plate from slipping out during use. When screening, the raw materials are discharged through the discharge port. To maintain the screen plate, pressing the baffle allows it to retract into the internal groove, thus releasing the positioning and facilitating its removal. This design makes it easy to disassemble and maintain the screen plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides a raw material screening device for manufacturing white marble sand, comprising a main body 1 and a support column 2.

[0027] Reference Figures 1-3As shown, support columns 2 are evenly fixed to the bottom of the main body 1. A feed inlet 3 is provided on one side of the top of the main body 1. A metering structure 4 is installed on one side of the feed inlet 3. A discharge port 5 is provided on one side of the bottom of the main body 1. The metering structure 4 includes a drive motor 401, a metering shaft 402, a metering plate 403, a transmission belt 404, an output shaft 405, and a cam 406. The drive motor 401 is installed on one side of the feed inlet 3. A metering shaft 402 is provided on one side of the drive motor 401. Metering plates 403 are evenly arranged on the outer wall of the metering shaft 402. A transmission belt 404 is provided on the side near the drive motor 401. Output shafts 405 are evenly arranged on the inner wall of the transmission belt 404. Cams 406 are fixed on one side of each output shaft 405. The metering shaft 402 extends into the interior of the feed inlet 3. The metering plates 403 are evenly distributed on the outer wall of the metering shaft 402. The output shafts 405 are symmetrically distributed on the inner wall of the transmission belt 404. One side of the transmission belt 404 extends into the interior of the main body 1. The limiting grooves 6 are symmetrically distributed on the main body 1. The top of the cam 406 abuts against the bottom of the sieve plate 7.

[0028] In the process of manufacturing white marble sand, the raw materials need to be screened and filtered to remove impurities and separate raw materials of different sizes. The two sets of screen plates 7 have different screen holes, which makes the raw materials screened by the two sets of screen plates 7 of different sizes and facilitates the impurities to fall into the body 1 and be discharged through the impurity discharge port 5. The quantitative structure 4 is set so that the start drive motor 401 drives the quantitative shaft 402 to rotate, which makes the quantitative plate 403 rotate inside the feed port 3. This makes the raw material entering the body 1 at an average rate and less likely to cause blockage. During the rotation of the quantitative shaft 402, the output shaft 405 is driven to rotate synchronously through the transmission belt 404. This causes the cam 406 on one side to push the screen plate 7 to vibrate inside the limiting groove 6 during rotation, thereby increasing the screening and filtering effect and greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, limit grooves 6 are evenly distributed inside the main body 1. Screen plates 7 are provided inside each limit groove 6. Maintenance structures 8 are provided on the outer wall of the main body 1 on one side of the limit groove 6. The maintenance structure 8 includes a discharge port 801, an internal groove 802, a baffle 803, and a return spring 804. The discharge port 801 is evenly distributed on the outer wall of the main body 1 on one side of the limit groove 6. Internal grooves 802 are provided on both sides of the discharge port 801. Baffles 803 are provided inside each internal groove 802. A return spring 804 is fixed on one side of each baffle 803. The internal grooves 802 are symmetrically distributed inside the main body 1 on both sides of the discharge port 801. The side of the return spring 804 away from the baffle 803 is fixedly connected to one side of the internal groove 802.

[0030] During long-term use, the screen plate 7 may be damaged. To facilitate disassembly and maintenance, a maintenance structure 8 is provided. When the screen plate 7 is inside the limiting groove 6, it is limited by the baffle 803, which prevents it from shifting position during operation. When maintenance is required, the baffle 803 is pressed into the internal groove 802, making it easy to remove the screen plate 7 for cleaning and maintenance, thus greatly increasing the functionality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
