Technical Field
[0001] This utility model relates to the field of quartz sand grading production technology, specifically a quartz sand grading device. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. During the production of quartz sand, it needs to be graded according to its particle size. Existing quartz sand grading devices cannot achieve grading and screening based on the required particle size. Therefore, to solve the above problem, this utility model provides a quartz sand grading device. Summary of the Invention
[0003] The purpose of this invention is to solve the problem that existing technologies cannot achieve grading and screening according to the required particle size, and to propose a quartz sand grading device.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a quartz sand grading device, characterized by: a housing containing a crushing mechanism and a screening mechanism, the crushing mechanism being positioned above the screening mechanism; a feed inlet at the top and a fourth discharge outlet at the bottom of the housing, with a feed hopper mounted on the feed inlet; the screening mechanism including a screening plate, with mounting strips corresponding to the screening plate on both inner walls of the housing, the mounting strips having embedded grooves for cooperation with the screening plate, and both the screening plate and the mounting strips being inclined; a discharge outlet for the screening plate to enter and exit is provided on one side wall of the housing at the lower end of the screening plate, with a baffle connected to the end of the screening plate on this side, the screening plate and the baffle being hinged by a rotating shaft, the baffle flipping up to cover the discharge outlet; threaded holes are provided at both ends of the rotating shaft, with fastening bolts for fixing the rotating shaft and the housing wall in the threaded holes. Through the structure of the screening mechanism, not only can the screening plate be disassembled and cleaned, but screening plates with different mesh sizes can also be replaced as needed.
[0005] As a further embodiment of this invention: a supporting triangular handle is provided on the back of the baffle, the size and angle of which correspond to the inclination angle of the screening plate. The size of the baffle matches the size of the discharge port on the wall of the housing. A movable buckle for fixing the baffle is provided on the housing above the discharge port. With the supporting triangular handle, when removing the screening plate, the handle on the side wall of the housing can be used as a handle for convenient operation. When discharging, the supporting triangular handle is on the back of the baffle, ensuring that the baffle and screening plate are on the same horizontal plane. The baffle acts as a guide for easy discharge, while the supporting triangular handle provides support. By setting the size of the baffle to match the size of the discharge port, when discharge is not required, the baffle flips over to cover the discharge port and is fixed by the movable buckle, thereby ensuring the airtightness of the housing.
[0006] As a further embodiment of this utility model: there are three screening plates, namely, a first screening plate, a second screening plate and a third screening plate from top to bottom. The mesh size of the first screening plate is larger than that of the second screening plate, and the mesh size of the second screening plate is larger than that of the third screening plate.
[0007] A first discharge port is provided on the box wall at the end where the first screening plate is connected to the baffle; a second discharge port is provided on the box wall at the end where the second screening plate is connected to the baffle; and a third discharge port is provided on the box wall at the end where the third screening plate is connected to the baffle. A guide plate is provided at the bottom of the box, forming a fourth discharge port. By setting up screening plate structures with three different mesh sizes and four discharge ports, four different particle sizes of quartz sand can be screened out.
[0008] As a further embodiment of this invention: a support plate is provided between the middle of the two mounting strips, which fits tightly against the screening plate, and a vibrator is provided on the support plate. The vibrator accelerates the screening process by oscillating the screen.
[0009] As a further embodiment of this invention: the crushing mechanism includes two crushing rollers that move in opposite directions, each roller having a plurality of meshing crushing teeth. A drive mechanism for rotating the two crushing rollers is located outside the housing. Crushing teeth that mesh with the two crushing rollers are also provided on the inner walls of both sides of the housing. This crushing mechanism effectively crushes quartz sand, preventing large particles from affecting the subsequent screening process.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The screening mechanism features a detachable screening plate, facilitating cleaning and allowing for replacement with different mesh sizes to meet varying particle size requirements. Multiple layers of screening plates with varying mesh sizes enable graded screening of quartz sand with different particle sizes. A triangular handle on the back of the baffle provides convenient operation when disassembling the screening plate. During discharge, the handle, located on the back of the baffle, ensures the baffle and screening plate are level, allowing the baffle to act as a guide for easy discharge while the handle provides support. The baffle's size matches the discharge port size; when discharge is not needed, the baffle flips over to cover the discharge port and is secured with a snap-fit mechanism, ensuring a tight seal. A crushing mechanism further pulverizes the quartz sand, preventing large particles from interfering with subsequent screening. Attached Figure Description

[0019] 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 scope of protection of the present utility model.
[0020] Please see the appendix Figure 1-5 A quartz sand grading device includes a housing 1, within which a crushing mechanism and a screening mechanism are installed. The crushing mechanism is positioned above the screening mechanism. The housing 1 has a feed inlet at the top and a fourth discharge outlet 3 at the bottom, with a feed hopper 2 mounted on the feed inlet. The screening mechanism includes a screening plate 8. Mounting strips 13, corresponding to the screening plate 8, are respectively installed on the inner walls of both sides of the housing 1. The mounting strips 13 have embedded grooves that cooperate with the screening plate 8. Both the screening plate 8 and the mounting strips 13 are inclined. A discharge outlet for the screening plate 8 is located on one side wall of the housing 1 at the lower end of the screening plate 8. A baffle 9 is connected to the end of the screening plate 8 on this side. The screening plate 8 and the baffle 9 are hinged by a rotating shaft 10, with the baffle 9 flipping up to cover the discharge outlet. Threaded holes are provided at both ends of the rotating shaft 10, with fastening bolts 12 for fixing the rotating shaft 10 to the housing wall. The screening mechanism allows for the disassembly and cleaning of the screening plate 8, as well as the replacement of screening plates 8 with different mesh sizes as needed.
[0021] A supporting triangular handle 11 is provided on the back of the baffle 9. The size and angle of the supporting triangular handle 11 correspond to the inclination angle of the screening plate 8. The size of the baffle 9 matches the size of the discharge port on the wall of the box 1. A movable buckle 7 for fixing the baffle 9 is provided on the box 1 above the discharge port. The supporting triangular handle 11 allows for easy operation as a handle on the side wall of the box 1 when disassembling the screening plate 8. During discharge, the supporting triangular handle 11 is on the back of the baffle 9, ensuring that the baffle 9 and the screening plate 8 are on the same horizontal plane. The baffle 9 acts as a guide for easy discharge, while the supporting triangular handle 11 provides support. By setting the size of the baffle 9 to match the size of the discharge port, when discharge is not required, the baffle 9 flips over to cover the discharge port and is fixed by the movable buckle 7, thus ensuring the airtightness of the box 1.
[0022] There are three screening plates 8, which are, from top to bottom, a first screening plate 81, a second screening plate 82 and a third screening plate 83. The mesh size of the first screening plate 81 is larger than that of the second screening plate 82, and the mesh size of the second screening plate 82 is larger than that of the third screening plate 83.
[0023] A first discharge port 4 is provided on the wall of the housing 1 at one end of the first screening plate 81 connected to the baffle 9; a second discharge port 5 is provided on the wall of the housing 1 at one end of the second screening plate 82 connected to the baffle 9; and a third discharge port 6 is provided on the wall of the housing 1 at one end of the third screening plate 83 connected to the baffle 9. A guide plate is provided at the bottom of the housing 1, and the guide plate forms a fourth discharge port 3. By setting up screening plates 8 with three different mesh sizes and four discharge ports, four different particle sizes of quartz sand can be screened out.
[0024] A support plate 14 is provided between the middle of the two mounting strips 13, which fits tightly against the screening plate 8. A vibrator 15 is provided on the support plate 14. The vibrator 15 can play a oscillating role during screening by the screening plate 8 to accelerate the screening process.
[0025] The crushing mechanism includes two counter-moving crushing rollers 16, each with a plurality of meshing crushing teeth. A drive mechanism for rotating the two crushing rollers 16 is located outside the housing 1. Crushing teeth that mesh with the two crushing rollers 16 are also located on the inner walls of both sides of the housing 1. This crushing mechanism effectively crushes quartz sand, preventing large particles from affecting the subsequent screening process.
[0026] During use, the discharge port of the housing 1 is sealed. First, the quartz sand raw material enters the housing 1 from the feed hopper 2 and reaches the crushing mechanism. After being crushed by the crushing roller 16, it reaches the first screening plate 81 for screening. The quartz sand after screening through the first screening plate 81 reaches the second screening plate 82 for screening, and then reaches the third screening plate 83 for screening. Finally, the quartz sand after screening through the third screening plate 83 reaches the fourth discharge port 3 for collection. Simultaneously with multi-stage screening, the vibrator 15 is turned on to vibrate the screening plates 8, thereby accelerating the screening efficiency of the screening plates 8. After screening is completed, the movable latch 7 is opened, and under the support of the supporting triangular handle 11, the baffle 9 is flipped to the same plane as the screening plates 8. At this time, the baffle 9 acts as a guide plate for convenient discharge. Because the mesh size of the first screening plate 81 is larger than that of the second screening plate 82, and the mesh size of the second screening plate 82 is larger than that of the third screening plate 83, quartz sand of varying particle sizes can be obtained from the first discharge port 4, the second discharge port 5, and the third discharge port 6, achieving multi-layer grading of the quartz sand. When it is necessary to disassemble and clean the screening plate 8, or when grading is required according to different particle size requirements, after discharging the material, remove the fastening bolts 12 on the two outer walls of the housing 1, and then pull the support triangular handle 11 to slide the screening plate 8 out of the discharge port on the side wall of the housing 1 through the sliding groove on the mounting strip 13. After disassembly, the screening plate 8 can be cleaned. When installing the screening plate 8, different mesh sizes can be used to replace the screening plate 8 according to the quartz sand grading requirements.
