Description

A dust suppression device for quartz sand screening Technical Field

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

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Due to its unique physical and chemical properties, quartz sand is used in aviation, aerospace, electronics, and machinery. During the screening process of quartz sand using a vibrating screen, dust is emitted, which can easily pollute the on-site environment and affect the physical and mental health of the workers.

[0003] Existing dust collection devices for quartz sand screening typically involve installing a dust collection hood above the vibrating screen. A fan generates suction above the hood to collect the airborne dust. However, the vibration at the screen's discharge port also causes some dust to be airborne, making collection difficult. Furthermore, the collected dust is usually stored in filter bags, but after a period of time, a significant amount of dust accumulates inside the filter bags, reducing their permeability and decreasing the suction at the dust collection hood, thus reducing the dust collection efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dust suppression device for quartz sand screening to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dust suppression device for quartz sand screening includes:

[0007] A dust collection assembly is installed on the upper end of the vibrating screen. The dust collection assembly includes a dust collection cover fixedly covering the upper end of the vibrating screen. A dust collection pipe is fixedly installed on the upper end of the discharge port of the vibrating screen. A ring pipe is fixedly installed on the outer surface of the dust collection cover. Multiple dust collection ports are fixedly connected at equal intervals on the outer surface of the ring pipe. A collection bag is installed at the discharge port of the vibrating screen.

[0008] A filter assembly is disposed on one side of the vibrating screen. The filter assembly includes a filter chamber, in which a filter cylinder is fixedly installed. A first spiral blade is rotatably connected inside the filter cylinder.

[0009] The feeding assembly is fixedly installed on the lower surface of the filter chamber.

[0010] Furthermore, all of the aforementioned dust collection ports are fixedly connected to the dust collection hood, the upper end of the dust collection hood is fixedly connected to the feeding port, and the annular pipe and the dust collection pipe are fixedly connected to the air gathering pipe.

[0011] Furthermore, a fan is fixedly installed at the upper end of the filter chamber, the air inlet of the fan is fixedly connected to the filter chamber through a pipe, and the air gathering pipe is fixedly connected to the filter chamber inside the filter cartridge through a flexible hose.

[0012] Furthermore, the lower end of the first spiral blade is fixedly connected to the second spiral blade via a bracket, the upper end of the first spiral blade is fixedly connected to a rotating frame, and the upper end of the rotating frame movably penetrates the filter chamber. The upper surface of the filter chamber is fixedly mounted with a first motor via a bracket, and the output end of the first motor and the upper end of the rotating frame are fixedly mounted with two meshing gears.

[0013] Furthermore, the feeding assembly includes:

[0014] The feed pipe is fixedly installed on the lower surface of the filter chamber and is fixedly connected to the lower end of the filter cartridge;

[0015] The support frame is fixedly installed inside the upper part of the feed pipe;

[0016] The blocking plate is placed between the first and second helical blades and is fixedly connected to the support frame.

[0017] Preferably, a screw rod is rotatably connected inside the feeding pipe, and a second motor capable of driving the screw rod to rotate is fixedly installed at one end of the feeding pipe.

[0018] Preferably, a storage frame is fixedly embedded at the upper end of the outer surface of the feed pipe, a baffle is slidably connected inside the storage frame, and an electric push rod is fixedly installed at the lower end of the filter chamber, with the output end of the electric push rod fixedly connected to the baffle.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By operating the fan, the dust collected by the dust collection pipe and dust collection port is discharged into the filter cartridge. After air filtration, it is discharged by the fan. The dust is filtered and collected by the filter cartridge. Thus, by setting dust collection pipes above the vibrating screen and above the discharge port of the vibrating screen, the dust flying in two places is collected, reducing the dust flying due to vibration when the material is discharged from the discharge port.

[0021] 2. When motor number one operates, it drives the first and second spiral blades to rotate. The first spiral blade scrapes the dust off the inner wall of the filter cartridge downwards, while the second spiral blade scrapes the scraped dust towards the middle of the lower end of the filter cartridge, causing the dust to fall into the feed pipe. Thus, the dust is collected through the filter cartridge. The rotation of the first and second spiral blades scrapes the dust off the inner wall of the filter cartridge and then discharges it through the feed assembly, maintaining the permeability of the filter cartridge and preventing a decrease in suction at the dust collection pipe and dust collection port.

[0022] 3. The electric push rod extends, causing the baffle to block the feeding pipe and prevent air from escaping from the feeding pipe. After the dust accumulates for a period of time, the baffle moves into the storage frame, opening the feeding pipe and allowing the dust to fall down. The No. 2 motor runs, driving the screw to rotate and expelling the dust inside the feeding pipe, while preventing the dust from being carried away by the air from the feeding pipe.

[0029] 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.

[0030] Please refer to Figures 1-5. In this embodiment of the present invention, a dust collection device for quartz sand screening includes a dust collection assembly 2 installed on the upper end of a vibrating screen 1. The dust collection assembly 2 includes a dust collection cover 201 fixedly covering the upper end of the vibrating screen 1. A dust collection pipe 203 is fixedly installed on the upper end of the discharge port of the vibrating screen 1. A ring pipe 204 is fixedly installed on the outer surface of the dust collection cover 201. Multiple dust collection ports 205 are fixedly connected at equal intervals on the outer surface of the ring pipe 204. A collection bag 207 is installed at the discharge port of the vibrating screen 1. A filter assembly 3 is disposed on one side of the vibrating screen 1. The filter assembly 3 includes a filter chamber 301. A filter cylinder 304 is fixedly installed inside the filter chamber 301. A spiral blade 305 is rotatably connected inside the filter cylinder 304. A feeding assembly 4 is fixedly installed on the lower surface of the filter chamber 301.

[0031] Specifically, the dust collection hood 201 covers the upper part of the vibrating screen 1 to prevent the dust from drifting into the outside air. The dust collection pipe 203 collects the dust drifting at the discharge port of the vibrating screen 1. The collection bag 207 reduces the diameter of the quartz sand discharge port to prevent excessive dust from drifting. The filter assembly 3 filters the dust and discharges it through the discharge assembly 4.

[0032] Example 1

[0033] As shown in Figures 1 and 2, in this embodiment, multiple dust collection ports 205 are fixedly connected to the dust collection hood 201. The upper end of the dust collection hood 201 is fixedly connected to the feeding port 202. The ring pipe 204 and the dust collection pipe 203 are fixedly connected to the air gathering pipe 206. The upper end of the filter chamber 301 is fixedly installed with a fan 302. The air inlet of the fan 302 is fixedly connected to the filter chamber 301 through a pipe. The air gathering pipe 206 is fixedly connected to the filter chamber 301 inside the filter cartridge 304 through a flexible hose.

[0034] In this embodiment, the blower 302 operates, generating suction at the filter chamber 301 and filter cartridge 304. Through the connection of the hose, the dust collected by the dust collection pipe 203 and the dust collection port 205 is discharged into the filter cartridge 304. After air filtration, it is discharged through the blower 302. The dust is filtered and collected by the filter cartridge 304. Thus, by setting the dust collection pipe 203 above the vibrating screen 1 and above the discharge port of the vibrating screen 1, the dust flying in the two places is collected, reducing the dust flying due to vibration when the material is discharged from the discharge port.

[0035] As shown in Figures 3 and 4, in this embodiment, a second spiral blade 306 is fixedly connected to the lower end of the first spiral blade 305 via a bracket, and a rotating frame 307 is fixedly connected to the upper end of the first spiral blade 305. The upper end of the rotating frame 307 movably passes through the filter chamber 301. A first motor 308 is fixedly installed on the upper surface of the filter chamber 301 via a bracket. Two meshing gears 309 are fixedly installed at the output end of the first motor 308 and the upper end of the rotating frame 307.

[0036] In practice, motor 308 operates, and through the meshing transmission of gear 309, it causes spiral blades 305 and 306 to rotate. Spiral blade 305 scrapes the dust from the inner wall of filter cartridge 304 downwards, while spiral blade 306 scrapes the scraped dust towards the lower middle of filter cartridge 304, causing the dust to fall into the feed pipe 401. Thus, the dust is collected through filter cartridge 304. The rotation of spiral blades 305 and 306 scrapes the dust from the inner wall of filter cartridge 304, and then discharges it through feed assembly 4, maintaining the permeability of filter cartridge 304 and preventing a decrease in suction at dust collection pipe 203 and dust collection port 205.

[0037] As shown in Figures 3-5, in this embodiment, the feeding assembly 4 includes: a feeding pipe 401 fixedly installed on the lower surface of the filter chamber 301 and fixedly connected to the lower end of the filter cartridge 304; a support frame 402 fixedly installed at the upper end of the inside of the feeding pipe 401; a blocking plate 405 disposed between the first spiral blade 305 and the second spiral blade 306 and fixedly connected to the support frame 402; a spiral rod 407 is rotatably connected inside the feeding pipe 401; and a second motor 408 capable of driving the spiral rod 407 to rotate is fixedly installed at one end of the feeding pipe 401.

[0038] In practice, the blocking plate 405 blocks the area above the second spiral blade 306 to prevent dust from gathering in the middle and floating upwards under the influence of air. This causes the dust to move along a specific trajectory. The second motor 408 operates, driving the spiral rod 407 to rotate, thus discharging the dust from inside the feed pipe 401.

[0039] Example 2

[0040] Based on Example 1, in order to compensate for the problem that air entering the feed pipe 401 can easily cause air to drift.

[0041] As shown in Figure 5, in this embodiment, a storage frame 404 is fixedly embedded at the upper end of the outer surface of the feed pipe 401, and a baffle 403 is slidably connected inside the storage frame 404. An electric push rod 406 is fixedly installed at the lower end of the filter chamber 301, and the output end of the electric push rod 406 is fixedly connected to the baffle 403.

[0042] In practice, the electric push rod 406 extends and pushes the baffle 403 to move, so that the baffle 403 blocks the discharge pipe 401 to prevent air from being discharged from the discharge pipe 401. After the dust accumulates for a period of time, the baffle 403 moves into the storage frame 404 and opens the discharge pipe 401, allowing the dust to fall down and be discharged uniformly. At the same time, it prevents the dust from being carried away by the air discharged from the discharge pipe 401 and causing dust to drift.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
