Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, specifically to a rotary quartz sand screening device. Background Technology

[0002] Rotary screening of quartz sand is a process that uses rotary screening equipment to classify raw quartz sand by particle size, separating sand particles of different sizes to obtain finished sand raw materials with particle size ranges.

[0003] Patent application CN202210131051.2 discloses a rotary quartz sand screening device, including a screening box, a screen cylinder, a feeding mechanism communicating with the screen cylinder, and a discharge hood installed below the screening box and communicating with the inner cavity of the screening box. The screen cylinder is provided with a slag discharge port on the right side. The feeding mechanism also includes a hot air blower installed on the screening box.

[0004] However, when existing screening equipment screens quartz sand, some quartz sand that meets the particle size requirement remains. This causes the residual quartz sand that meets the particle size requirement to mix with the larger quartz sand and be discharged together, resulting in a waste of raw materials. Utility Model Content

[0005] The purpose of this invention is to provide a rotary quartz sand screening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand rotary screening device, including a screening chamber, a motor fixedly connected to the top of the screening chamber, the motor being a YE3-100L2-4 three-phase asynchronous motor, which serves as a power source to drive the drive rod to rotate, the output end of the motor being fixedly connected to the drive rod via a coupling, and a flow guiding mechanism being provided inside the screening chamber;

[0007] The flow guiding mechanism includes;

[0008] A guide plate is fixedly connected to the top of the inner wall of the screening chamber via a connecting rod. The guide plate is concave and hollow, used to guide the flow of quartz sand. A diverter plate is fixedly connected to the bottom of the guide plate, used to guide and divert the quartz sand. A baffle plate is fixedly connected to the bottom of the diverter plate, and the inclined surface of the outer wall of the baffle plate is used to guide the flow of quartz sand. The baffle plate guides the flow during the quartz sand screening process. By repeatedly feeding the quartz sand, large particles of quartz sand are screened by inertia and guided to the edge of the screening plate for repeated screening. This ensures that the quartz sand with the standard particle size is fully screened, avoiding waste of standard-compliant quartz sand.

[0009] According to the above technical solution, a screening plate is fixedly connected to the bottom of the drive rod by bolts, a support block is fixedly connected to the inner wall of the screening chamber, and a support wheel is rotatably connected to the inner wall of the support block via a rotating shaft. The outer wall of the support wheel contacts the bottom of the screening plate and rolls along the bottom of the screening plate. The support wheel is used to support the screening plate, and the screening plate is used to screen the quartz sand. A feeding plate is fixedly connected to the inner wall of the screening plate, and the feeding plate is used to feed the quartz sand. By feeding the quartz sand through the feeding plate, the quartz sand is screened repeatedly to avoid the incomplete screening of quartz sand that meets the particle size requirements, thus avoiding waste of quartz sand.

[0010] According to the above technical solution, a distribution bin is provided on the inner wall of the screening bin. A baffle is fixedly connected to the inner wall of the screening bin. The position of the baffle is matched with the position of the distribution bin. The position of the baffle is lower than the inclined surface of the baffle. The outer wall of the baffle is an arc-shaped surface, which is used to intercept large particles of quartz sand. A cover plate is bolted to the top of the distribution bin. The distribution bin is used to collect large particles of quartz sand. By cooperating with the baffle, the large particles of quartz sand are intercepted by the baffle due to inertia and collected, reducing the interference of large particles of quartz sand on quartz sand of the correct particle size during the screening process.

[0011] According to the above technical solution, the top of the screening bin is fixedly connected to a feed inlet, which is located inside the outer diameter of the guide plate. This feed inlet is used to feed quartz sand into the guide plate and guide the quartz sand through the guide plate. The bottom of the screening bin is fixedly connected to a discharge outlet. The inner wall of the cover plate is fixedly connected to the outer wall of the screening bin by bolts. The cover plate is made of transparent material and is used to observe the collection situation inside the distribution bin. Through the transparent cover plate, the collection of large-particle quartz sand inside the distribution bin can be observed, which facilitates the timely collection of large-particle quartz sand by the staff and avoids excessive accumulation.

[0012] According to the above technical solution, a scraper is fixedly connected to the bottom of the second baffle, a third baffle is fixedly connected to the inner wall of the scraper, and a fourth baffle is fixedly connected to the inner wall of the second baffle. The bottom of the scraper contacts the inner wall of the screening plate and is used to stir the quartz sand. The inner wall of the second baffle contacts the outer wall of the feeding plate and is used to isolate the quartz sand when the feeding plate feeds it.

[0013] According to the above technical solution, the bottom of the baffle plate is in contact with the inner wall of the screening plate to intercept the quartz sand and increase the residence time of the quartz sand on the inclined surface of the inner wall of the screening plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model guides the flow of quartz sand during the screening process by using baffle two. By repeatedly feeding quartz sand, large particles of quartz sand are screened by inertia, and the quartz sand is guided to the edge of the screening plate for repeated screening. This ensures that quartz sand with the standard particle size is fully screened, avoiding waste of standard quartz sand.

[0016] 2. This utility model feeds quartz sand through a feeding plate and performs repeated screening of the quartz sand to avoid the incomplete screening of quartz sand that meets the particle size requirements, thus avoiding waste of quartz sand.

[0017] 3. This utility model uses baffle one and baffle two to intercept large particles of quartz sand by inertia and collect them, thereby reducing the interference of large particles of quartz sand on quartz sand that meets the particle size requirements during the screening process.

[0018] 4. This utility model allows for the observation of the collection of large-particle quartz sand inside the distribution bin through a transparent cover, facilitating timely collection of large-particle quartz sand by staff and preventing excessive accumulation. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Example 1, please refer to Figures 1-4 This utility model provides a technical solution: a rotary quartz sand screening device, including a screening chamber 100. A motor 102 is fixedly connected to the top of the screening chamber 100. A drive rod 104 is fixedly connected to the output end of the motor 102 via a coupling. A screening plate 106 is fixedly connected to the bottom of the drive rod 104 via bolts. A support block 105 is fixedly connected to the inner wall of the screening chamber 100. A support wheel 111 is rotatably connected to the inner wall of the support block 105 via a rotating shaft. The outer wall of the support wheel 111 contacts the bottom of the screening plate 106 and rolls along the bottom of the screening plate 106. The support wheel 111 is used to support the screening plate 106, which is used to screen the quartz sand. A feeding plate 110 is fixedly connected to the inner wall of the screening plate 106 for feeding the quartz sand. A distribution chamber 107 is opened on the inner wall of the screening chamber 100. A baffle 109 is fixedly connected to the inner wall of the screening chamber 100. The position of the baffle 109 matches the position of the distribution chamber 107. The position of the baffle 109 is lower than the inclined surface of the baffle 203. The outer wall of the baffle 109 is an arc-shaped surface, which is used to intercept large particles of quartz sand. A cover plate 108 is bolted to the top of the distribution chamber 107. The distribution chamber 107 is used to collect large particles of quartz sand. The top of the screening chamber 100 is fixedly connected to the inlet 101. The inlet 101 is set inside the outer diameter of the guide plate 201, which is used to feed quartz sand into the inside of the guide plate 201 and guide the quartz sand through the guide plate 201. The bottom of the screening chamber 100 is fixedly connected to the outlet 103. The inner wall of the cover plate 108 is fixedly connected to the outer wall of the screening chamber 100 by bolts. The cover plate 108 is made of transparent plate, which is used to observe the collection situation inside the distribution chamber 107.

[0028] When the rotary quartz sand screening equipment is put into use, quartz sand is fed into the screening chamber 100 through the feed inlet 101. After falling into the screening chamber 100, the quartz sand falls onto the surface of the guide plate 201, and is guided by the motor 102 to fall onto the surface of the baffle 203. The baffle 203 guides the quartz sand, causing it to fall onto the inner edge of the screening plate 106. The quartz sand then flows from the inner edge of the screening plate 106 along the inner wall of the screening plate 106. The inclined plate 106 rolls towards the center of the inner wall to screen the quartz sand. The motor 102, acting as a power source, drives the drive rod 104 to rotate, causing the drive rod 104 to rotate the screening plate 106 within the screening chamber 100, thus screening the quartz sand. During rotation, the support wheel 111 rolls on the screening plate 106 through friction, supporting the plate. After screening, the quartz sand accumulates at the center of the screening plate 106. At the screen plate 106, the feeding plate 110 is rotated, causing the feeding plate 110 to rotate inside the baffle 4 206 to feed the quartz sand. The quartz sand that is not completely screened is fed to the surface of the baffle 2 203 and then guided by the baffle 2 203 and falls back to the inner edge of the screen plate 106 for screening. The large particles of quartz sand guided by the baffle 2 203 have greater inertia, and the parabolic trajectory of the falling particles is farther than that of the relatively smaller diameter quartz sand. This causes the larger quartz sand to be intercepted by the baffle 1 109 and enter the distribution bin 107 for collection. When a large amount of large-diameter quartz sand is collected in the distribution bin 107, the staff observes the large-sized quartz sand inside the distribution bin 107 through the cover plate 108, and then removes the cover plate 108 to clean the large-sized quartz sand collected inside the distribution bin 107. After screening, the quartz sand that meets the particle size requirements is discharged through the discharge port 103 for collection.

[0029] Example 2, based on Example 1, please refer to... Figures 5-6The present invention provides the following technical solution: A flow guiding mechanism 200 is provided inside the screening chamber 100. The flow guiding mechanism 200 includes a flow guiding plate 201. The top of the flow guiding plate 201 is fixedly connected to the top of the inner wall of the screening chamber 100 via a connecting rod. The flow guiding plate 201 is concave and hollow, used to guide the flow of quartz sand. A flow dividing plate 202 is fixedly connected to the bottom of the flow guiding plate 201, used to guide and divide the quartz sand. A baffle 203 is fixedly connected to the bottom of the flow dividing plate 202. The inclined surface of the outer wall of the baffle 203 is used to guide the flow of quartz sand. A scraper 204 is fixedly connected to the bottom of plate 203. A baffle 3 205 is fixedly connected to the inner wall of scraper 204. A baffle 4 206 is fixedly connected to the inner wall of baffle 203. The bottom of scraper 204 contacts the inner wall of screening plate 106 and is used to stir the quartz sand. The inner wall of baffle 203 contacts the outer wall of feeding plate 110 and is used to isolate the quartz sand when feeding it onto feeding plate 110. The bottom of baffle 3 205 contacts the inner wall of screening plate 106 and is used to intercept the quartz sand and increase the residence time of the quartz sand on the inclined surface of the inner wall of screening plate 106.

[0030] Quartz sand enters the screening chamber 100 through the feed inlet 101 and falls onto the surface of the guide plate 201. The hollow concave shape of the guide plate 201 guides the quartz sand, causing it to slide along the inclined inner wall of the guide plate 201 and fall onto the surface of the baffle 203. The baffle 203 guides the quartz sand, and the diversion plate 202 diverts the quartz sand, allowing it to fall evenly onto the inner edge of the screening plate 106 and down the inclined inner wall of the screening plate 106 for screening. While the quartz sand is being screened along the inclined surface of the screening plate 106, the screening plate 106 rotates, and the scraper 204 agitates the quartz sand, improving the screening efficiency. At the same time, the baffle 3 205 intercepts the quartz sand, increasing the residence time of the quartz sand on the inclined surface of the screening plate 106, ensuring that the quartz sand is fully screened.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
