Description

Technical Field

[0001] This utility model relates to the field of fly ash conveying technology, and in particular to a fly ash conveying structure. Background Technology

[0002] Fly ash refers to fine solid particulate matter produced during combustion. It can be generated in activities such as fossil fuel combustion, industrial production processes, and waste incineration. Fly ash can remain suspended in the atmosphere for a long time, posing an environmental pollution problem. Therefore, it is usually collected using specialized fly ash collection devices and transported to designated locations for further treatment via pipelines through fly ash conveying structures, thereby reducing its impact on the environment.

[0003] However, since most fly ash conveying structures use pneumatic conveying to transport fly ash, and most of the existing fly ash conveying structures on the market are not convenient for workers to replace the filter screen, which increases the difficulty of operation for workers. In addition, most of the existing fly ash conveying structures on the market are not convenient for cleaning the inside of the tank where fly ash is placed, making the cleaning of fly ash structures quite troublesome.

[0004] Therefore, those skilled in the art have provided a fly ash conveying structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fly ash conveying structure. The connecting rod on the limiting cylinder in the connecting mechanism is inserted into the rotating groove on the fixed cylinder. A rotating ring threaded to the fixed cylinder drives a locking block to secure the connecting rod, facilitating filter replacement. Meanwhile, a servo motor in the rotating mechanism drives a rotating rod to rotate a scraper on a cross bracket inside the transfer tank. This, combined with the addition of cleaning fluid and water to the transfer tank, facilitates cleaning of the tank's interior.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fly ash conveying structure includes a transfer tank, a connecting mechanism, and a rotating mechanism. A support frame is fixedly connected to the lower end of the outer wall of the transfer tank. A fan is installed on the other side of the upper end of the support frame. The connecting mechanism is installed on the other side of the transfer tank. The connecting mechanism includes a rotating ring and a limiting cylinder. A fixed cylinder is bolted to the air inlet of the fan. A filter cylinder is fixedly connected to the inner wall of the fixed cylinder. Four rotating grooves are formed on the outer wall of the fixed cylinder. Four locking blocks are fixedly connected to the middle of the inner wall of the rotating ring. Four connecting rods are fixedly connected to the outer wall of the rear end of the limiting cylinder. All connecting rods are engaged with the locking blocks. The front end of the inner wall of the rotating ring is threadedly connected to the fixed cylinder. A rotating mechanism is installed inside the transfer tank. A straight outlet pipe is connected through the center of the lower end of the transfer tank.

[0008] The above technical solution involves fixing the fixed cylinder to the air inlet of the fan, inserting four connecting rods fixedly connected to the limiting cylinder into the rotating grooves on the fixed cylinder, and using a rotating ring threaded to the fixed cylinder to drive the locking block to rotate and lock the connecting rods, thus fixing the cylindrical filter screen inside the filter cylinder. Rotating the rotating ring counterclockwise will cause the locking block to release the locking connection of the connecting rods, allowing the limiting cylinder to be removed and the filter screen inside the filter cylinder to be taken out, making it convenient for staff to replace the filter screen.

[0009] Furthermore, the rotating mechanism includes a rotating rod, a protective shell is fixedly connected to the center of the upper end of the transfer tank, a servo motor is provided on the bottom surface inside the protective shell, the output shaft of the servo motor is fixedly connected to the rotating rod, the lower end of the outer wall of the rotating rod penetrates the transfer tank and is fixedly connected to a cross bracket, and scrapers are fixedly connected to the side of the cross bracket away from the center of the rotating rod.

[0010] The above technical solution uses a servo motor in the rotating mechanism to drive the rotating rod to rotate, which in turn causes the cross bracket fixedly connected to the rotating rod to drive the scraper to rotate inside the transfer tank, scraping the inner wall of the transfer tank. This, combined with the addition of cleaning fluid and water to the inside of the transfer tank, facilitates the cleaning of the tank's interior by the staff.

[0011] Furthermore, a PLC control panel is fixedly connected to the outer wall of the front end of the support frame, and all the locking blocks slide inside the rotating groove;

[0012] The above technical solution allows operators to conveniently control the operating status of each electrical component in the fly ash structure by using a PLC control panel fixedly connected to the support frame. Furthermore, by utilizing four locking blocks that move inside the rotating groove, the locking blocks can rotate clockwise and tighten the rotating ring onto the fixed cylinder, thereby locking and securing the connecting rod fixedly connected to the limiting cylinder.

[0013] Furthermore, the inner wall of the limiting cylinder is slidably connected to the filter cylinder, and the rear end of the connecting rod passes through the rotating groove and is slidably connected to the fixed cylinder;

[0014] With the above technical solution, by sliding the limiting cylinder and the filter cylinder together, and by sliding the connecting rod and the fixed cylinder together, the limiting cylinder can be removed from the filter cylinder after the locking block is released from the connecting rod, and the filter screen placed inside the filter cylinder can be replaced.

[0015] Furthermore, the air outlet of the blower is fixedly connected to a connecting pipe, and an air supply solenoid valve is installed inside the connecting pipe. The lower end of the straight outlet pipe is connected to an air supply pipe, and the other side of the upper middle part of the transfer tank is connected to the air supply pipe.

[0016] The above technical solution involves fixing the fan to the connecting pipe and installing an air supply solenoid valve inside the connecting pipe to control whether the airflow passes through the connecting pipe. The direct outlet pipe is connected to the gas transmission pipe, allowing the fly ash in the transfer tank to enter the gas transmission pipe.

[0017] Furthermore, a discharge solenoid valve is provided on one side of the gas transmission pipe, and one side of the connecting pipe is connected to the gas transmission pipe.

[0018] Through the above technical solution, the discharge solenoid valve installed inside the gas transmission pipe can control the opening and closing of the gas transmission pipe and the external pipeline, so that the connecting pipe and the gas transmission pipe are connected in a continuous manner, allowing the high-speed airflow drawn in by the blower to enter the transfer tank through the gas transmission pipe and discharge the fly ash.

[0019] Furthermore, a feed pipe is connected through to the rear end of the upper middle part of the transfer tank, and a feed solenoid valve is installed inside the feed pipe;

[0020] The above technical solution allows the feed solenoid valve installed inside the feed pipe to open and close the feed pipe, enabling the feed pipe connected to the fly ash collection device to send fly ash into the transfer tank for temporary storage.

[0021] Furthermore, an exhaust pipe is connected to the upper end of the outer wall of one side of the transfer tank, and an exhaust solenoid valve is installed inside the exhaust pipe.

[0022] By using the above technical solution, by opening the exhaust solenoid valve in the exhaust pipe that runs through the transfer tank, excess gas in the tank can be discharged when the feed solenoid valve is opened, allowing fly ash to smoothly enter the transfer tank.

[0023] This utility model has the following beneficial effects:

[0024] 1. The fly ash conveying structure proposed in this utility model is fixedly connected to the air inlet of the fan through a fixed cylinder in the connecting mechanism. Four connecting rods fixedly connected to the limiting cylinder are inserted into the rotating groove opened on the fixed cylinder. The rotating ring, which is threadedly connected to the fixed cylinder, drives the locking block to rotate and lock the connecting rods, thereby fixing the cylindrical filter screen placed inside the filter cylinder. Rotating the rotating ring counterclockwise can drive the locking block to release the locking connection of the connecting rods, allowing the limiting cylinder to be removed and the filter screen inside the filter cylinder to be taken out. This makes it easier for the staff to replace the filter screen and reduces the difficulty of operation for the staff.

[0025] 2. The fly ash conveying structure proposed in this utility model uses a servo motor in the rotating mechanism to drive the rotating rod to rotate, which causes the cross bracket fixedly connected to the rotating rod to drive the scraper to rotate inside the transfer tank, scraping the inner wall of the transfer tank. With the addition of cleaning fluid and water to the transfer tank, it is easier for workers to clean the inside of the tank, reducing the difficulty of cleaning the fly ash structure.

This is combined with the addition of cleaning fluid and water to the inside of the transfer tank 1 to facilitate the cleaning of the inside of the tank by the staff.

[0038] Working principle: When using this fly ash conveying structure, the operator first installs the device below the fly ash collection device and connects it to the feed pipe 9. Then, the operator uses the PLC control panel 2 to open the feed solenoid valve 10 and the exhaust solenoid valve 12 to allow the fly ash to enter the transfer tank 1. When the transfer tank 1 is almost full, the operator closes the feed solenoid valve 10 and the exhaust solenoid valve 12, opens the air supply solenoid valve 7, and uses the blower 4 to draw in air to briefly pressurize the transfer tank 1. Then, the operator opens the discharge solenoid valve 15 to allow the fly ash to be discharged from the straight outlet pipe 13 through the air supply pipe 14 and other conveying pipes connected to the air supply pipe 14, thus conveying the fly ash.

[0039] Secondly, the operator can rotate the rotating ring 504 counterclockwise to cause the locking block 505 to release the locking connection of the connecting rod 507, remove the limiting cylinder 506, and take out the filter screen inside the filter cylinder 502 for replacement. Then, the connecting rod 507 on the limiting cylinder 506 is inserted into the rotating groove 503 on the fixed cylinder 501, and the rotating ring 504 drives the locking block 505 to rotate and lock the connecting rod 507, thus fixing the filter cylinder 502.

[0040] Finally, the staff can use the PLC control panel 2 to start the servo motor 802 to drive the rotating rod 803 to rotate, so that the cross bracket 804 fixedly connected to the rotating rod 803 drives the scraper 805 to rotate inside the transfer tank 1 to scrape the inner wall of the transfer tank 1. In conjunction with opening the exhaust solenoid valve 12, the staff can add cleaning fluid and water into the transfer tank 1 through the exhaust pipe 11 to clean the residual clumps of fly ash inside the tank. After that, the staff can open the discharge solenoid valve 15 to discharge the wastewater.
