Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a low-dust, sealed conveying device for polyacrylamide. Background Technology

[0002] Polyacrylamide, as an important water-soluble polymer, is widely used in petroleum, wastewater treatment and other fields. The conveying of its powdered products is crucial. Traditional conveying methods use open manual feeding or screw and belt conveyors, which cause dust pollution. With the increasing requirements of industrial automation and environmental protection, the conveying needs to meet the requirements of high efficiency, airtightness, low dust loss and precise control. Therefore, it is of great significance to develop a conveying device that combines low dust, airtightness, high efficiency, stability and automation. We propose a low dust airtight conveying device for polyacrylamide.

[0003] The existing technology still has the following drawbacks in its use:

[0004] The existing polyacrylamide conveying device is an open design, which causes the powdered polyacrylamide to generate dust during the conveying process. This not only pollutes the surrounding environment, but also causes impurities in the air to be mixed into the polyacrylamide powder, resulting in contamination of the raw material. It also leads to a large amount of polyacrylamide powder loss during the transmission process.

[0005] In existing polyacrylamide conveying devices, when transporting powdered polyacrylamide, the powder is unstable during transport. A large amount of polyacrylamide powder tends to accumulate around the outlet of the conveying device, causing partial blockage. This can lead to difficulties and instability in discharging the material later on, which is not conducive to the accurate dosing of polyacrylamide.

[0006] In view of this, we propose a low-dust, closed conveying device for polyacrylamide to solve the existing problems. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a low-dust, closed conveying device for polyacrylamide, comprising a feed valve, a conveying assembly, a buffer pipe, and a mounting frame, wherein the feed valve is installed on the top of the conveying assembly through a connecting pipe;

[0009] A buffer pipe is fixedly installed at the bottom of the conveying assembly, and the buffer pipe is arranged vertically. A distribution pipe is fixedly installed at the bottom of the buffer pipe, and a discharge valve is fixedly installed at the bottom of the distribution pipe.

One side of the guide ring is connected to the air intake pipe.

[0013] Preferably, a bellows is fixedly installed on the top of the feed valve, and a feed pipe is fixedly installed on the top of the bellows.

[0014] Preferably, the diameter of the distribution pipe is larger than the diameter of the buffer pipe, and the side of the distribution pipe is provided with vent holes at equal intervals, and the bottom of the discharge valve is fixedly installed with a discharge pipe.

[0015] Preferably, a ball bearing is installed at the center of the mounting frame, a sealing cover is installed on the top of the ball bearing, a central shaft is installed at the center of the ball bearing, a plurality of second blades are installed on the portion of the central shaft above the mounting frame, and a plurality of first blades are fixedly installed on the top of the central shaft.

[0016] Preferably, the first scraper and the second scraper are respectively installed on the part of the central axis located below the mounting bracket, and the first scraper and the second scraper are symmetrically distributed with the central axis as the center.

[0019] Preferably, a screen is fixedly installed on the inner wall of the distribution pipe at several vent positions, and a distance of one to three centimeters is provided between the screen and the inner wall of the distribution pipe.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, by installing a distribution pipe at the bottom of the buffer pipe, can form a closed transmission pipeline by connecting the distribution pipe, the buffer pipe and the conveying components. Based on the siphon effect, it can drive the polyacrylamide powder entering the device to move, thereby achieving non-destructive transportation of polyacrylamide powder and reducing the probability of polyacrylamide powder being contaminated by the external environment during the transportation process.

[0022] This invention uses a first scraper and a second scraper mounted on the side of the central shaft, combined with a scraper and a distribution plate, to scrape the polyacrylamide powder inside the distribution tube. This causes the transported polyacrylamide powder to concentrate in the distribution tube and await discharge. The polyacrylamide powder inside the distribution tube is scraped in two directions by the distribution plate and the scraper, which makes the polyacrylamide powder inside the distribution tube evenly distributed. On the one hand, this facilitates the concentrated discharge of polyacrylamide powder and improves the smoothness of the discharge. On the other hand, it can prevent polyacrylamide powder from remaining inside the device and clogging the outlet when it is discharged. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-8 As shown, the present invention proposes a low-dust closed conveying device for polyacrylamide, including a feed valve 1, a conveying assembly 2, a buffer pipe 3, and a mounting frame 4. The feed valve 1 is installed on the top of the conveying assembly 2 through a connecting pipe 103. The conveying assembly 2 can use the siphon effect to drive the polyacrylamide powder to move inside the device, thereby realizing the transportation of polyacrylamide powder. This not only reduces the probability of polyacrylamide powder being contaminated during transportation, but also avoids the generation of a large amount of dust by the polyacrylamide powder through the closed environment. The feed valve 1 can control the opening and closing of the connecting pipe 103, so that when it is necessary to transfer polyacrylamide powder, the connecting pipe 103 is opened to suck the polyacrylamide powder into the device.

[0034] A buffer pipe 3 is fixedly installed at the bottom of the conveying component 2, and the buffer pipe 3 is arranged vertically. A distribution pipe 301 is fixedly installed at the bottom of the buffer pipe 3, and a discharge valve 303 is fixedly installed at the bottom of the distribution pipe 301. The buffer pipe 3 can guide the conveyed polyacrylamide powder, so that the transported polyacrylamide powder enters the distribution pipe 301 for even distribution and waiting for discharge. The distribution pipe 301 can cooperate with the internal components to evenly distribute the polyacrylamide powder, so that the polyacrylamide powder can be discharged more smoothly in the later stage, and prevent the polyacrylamide powder from remaining on the inner wall of the distribution pipe 301. The discharge valve 303 can control the opening and closing of the discharge pipe 302, and thus control the discharge of polyacrylamide powder when the conveying of polyacrylamide powder is completed.

[0035] The buffer tube 3 is fixedly installed with a mounting bracket 4, which can provide a mounting position for the central shaft 405 and its surrounding components to ensure that the central shaft 405 and its surrounding components can maintain stability when rotating.

[0036] Furthermore, the conveying assembly 2 includes a central pipe 201, the top end of which is connected to the connecting pipe 103 by bolts, and the bottom end of which is connected to the buffer pipe 3 by bolts. An installation platform 203 is fixedly mounted on the outside of the central pipe 201, and an air pump 204 is fixedly mounted on one side of the top of the installation platform 203. A control box is fixedly mounted on the top of the installation platform 203. The central pipe 201 can be connected to the connecting pipe 103 and the buffer pipe 3, thereby allowing the polyacrylamide powder to undergo low-temperature processing in a closed environment. Dust transport: The mounting platform 203 provides a mounting position for the top components. The air pump 204 is of type B60-8-YK. The air pump 204 can be electrically connected to the control box via a cable. After the control box is connected to an external power source, the air pump 204 is powered, which causes the air pump 204 to blow high-speed airflow into the guide ring 206 and the intake manifold 202 through the air intake pipe 205, thereby creating a negative pressure environment in the central pipe 201, so that the polyacrylamide powder can be drawn into the device and transferred to the distribution pipe 301.

[0037] Furthermore, an air inlet pipe 205 is fixedly installed on one side of the air pump 204, and a guide ring 206 is fixedly installed on the outer side of the central pipe 201. Several air intake manifolds 202 are fixedly installed at the bottom of the guide ring 206. The air intake manifolds 202 are inclined, and the bottom end of the air intake manifolds 202 passes through the central pipe 201 and extends into the interior of the central pipe 201. One side of the guide ring 206 is connected to the air inlet pipe 205. The air inlet pipe 205 allows the high-speed airflow blown in by the air pump 204 to enter the guide ring 206. The airflow then passes through the guide ring 206 and enters the air intake manifolds 202 respectively. The high-speed airflow is blown into the central pipe 201 through the inclined air intake manifolds 202, causing the air in the central pipe 201 to flow at high speed towards the distribution pipe 301, thereby drawing the polyacrylamide powder into the device and transmitting it to the distribution pipe 301.

[0038] Furthermore, a bellows 101 is fixedly installed on the top of the feed valve 1, and a feed pipe 102 is fixedly installed on the top of the bellows 101. The bellows 101 can provide an elastic connection between the feed valve 1 and the feed pipe 102, thereby ensuring the connection stability between the feed pipe 102 and the feed valve 1. The feed pipe 102 can be connected to an external storage container to draw polyacrylamide powder into the device for transportation.

[0039] Furthermore, the diameter of the distribution pipe 301 is larger than that of the buffer pipe 3, and the side of the distribution pipe 301 is provided with vent holes 305 at equal intervals. The bottom of the discharge valve 303 is fixedly installed with a discharge pipe 302. The vent holes 305 can allow air to be discharged from the distribution pipe 301, so that the polyacrylamide powder moving with the high-speed airflow is concentrated in the distribution pipe 301. When the discharge valve 303 is opened, the discharge pipe 302 can guide the polyacrylamide powder inside the distribution pipe 301 to be discharged.

[0040] Furthermore, a ball bearing is installed at the center of the mounting frame 4, a sealing cover is installed on the top of the ball bearing, a central shaft 405 is installed at the center of the ball bearing, a number of second blades 402 are installed on the part of the central shaft 405 above the mounting frame 4, and a number of first blades 401 are fixedly installed on the top of the central shaft 405. The central shaft 405 can be driven to rotate by the first blades 401 and the second blades 402, thereby driving the first scraper 406 and the second scraper 407 and their bottom components to rotate. The first blades 401 and the second blades 402 can be driven to rotate by the high-speed airflow in the buffer tube 3, thereby driving the central shaft 405 to rotate.

[0041] Furthermore, a first scraper 406 and a second scraper 407 are respectively installed on the part of the central shaft 405 located below the mounting bracket 4, and the first scraper 406 and the second scraper 407 are symmetrically distributed with the central shaft 405 as the center. Several ceramic beads 408 are fixedly installed on the side walls of the first scraper 406 and the second scraper 407. The first scraper 406 and the second scraper 407 can rotate with the central shaft 405, and the ceramic beads 408 installed on the side contact the screen 306, so that the ceramic beads 408 rub against the screen 306, causing the polyacrylamide powder adhering to the inside of the screen 306 to fall off. At the same time, the mesh inside the screen 306 is cleared to ensure that air can penetrate the screen 306 and be discharged from the exhaust port 305 to the distribution pipe 301.

[0042] Furthermore, a scraper 403 is installed at the bottom of the first scraper 406, and the scraper 403 is installed at an angle. A distribution plate 404 is installed at the bottom of the second scraper 407. The distribution plate 404 has several round holes inside, and the distribution plate 404 and the scraper 403 have the same tilt direction and tilt angle. When the scraper 403 rotates with the first scraper 406, it can smooth the polyacrylamide powder inside the distribution tube 301, so that the polyacrylamide powder is evenly distributed in the distribution tube 301. The distribution tube 301 can rotate synchronously with the second scraper 407, thereby scooping up the polyacrylamide powder inside the distribution tube 301, allowing the polyacrylamide powder to pass through the round holes inside, and smoothing it during the subsequent movement of the scraper 403, which can prevent the polyacrylamide powder inside the distribution tube 301 from clumping.

[0043] Furthermore, a transparent window 304 is provided on the side of the distribution tube 301, and scale lines are provided on the transparent window 304. The transparent window 304 allows for easy viewing of the polyacrylamide powder inside the distribution tube 301 from the outside of the device. When a certain amount of polyacrylamide powder is collected, the discharge valve 303 is opened to discharge the polyacrylamide powder inside the distribution tube 301.

[0044] Furthermore, a screen 306 is fixedly installed on the inner wall of the distribution tube 301 at several exhaust holes 305, and a distance of one to three centimeters is provided between the screen 306 and the inner wall of the distribution tube 301. The screen 306 can screen the air inside the distribution tube 301, so that the polyacrylamide powder is retained in the distribution tube 301, while the air passes through the screen 306 and is discharged from the distribution tube 301 through the exhaust holes 305, thereby enabling the air to continuously flow at high speed inside the device to transport the polyacrylamide powder.

[0045] Working principle: After the device is assembled, the inlet end of the feed pipe 102 is connected to the container storing polyacrylamide powder. Power is supplied to the air pump 204 via an external power source connected to the control box, causing the air pump 204 to blow high-speed airflow into the guide ring 206 and the air intake manifold 202. The discharge valve 303 is closed. As the air flows at high speed inside the device, it draws the polyacrylamide powder into the device. The powder then passes through the feed pipe 102, connecting pipe 103, central pipe 201, and buffer pipe 3 to reach the distribution pipe 301. The air passes through the screen 306 and exits the distribution pipe 301 through the exhaust port 305. The polyacrylamide powder is intercepted inside the screen 306. Simultaneously, the high-speed airflow drives the first fan blade 401 and the second fan blade 402 to rotate. The fan blade 402 drives the central shaft 405 and its bottom components to rotate. When the first scraper 406 and the second scraper 407 rotate, they cause the ceramic beads 408 to contact the inner side of the screen 306, scraping off the polyacrylamide powder attached to the inner side of the screen 306. When the distribution plate 404 makes a circular motion, it scoops up the polyacrylamide powder inside the distribution tube 301. Then the scraper 403 smooths the scooped-up polyacrylamide powder, so that the polyacrylamide powder is evenly distributed in the distribution tube 301. After a certain amount of polyacrylamide powder is collected inside the distribution tube 301, the air pump 204 and the feed valve 1 are turned off, and the discharge valve 303 is opened to discharge the polyacrylamide powder inside the distribution tube 301 in a concentrated manner, thus completing the low-dust transportation of polyacrylamide powder.

[0046] The above specific embodiments are merely several preferred embodiments of this utility model.
