Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a urea feeding device for aluminum processing, belonging to the field of mechanical equipment technology. Background Technology

[0002] In the aluminum processing industry, denitrification equipment is one of the key facilities for achieving environmentally friendly production. Denitrification equipment typically uses urea as a reducing agent, converting nitrogen oxides into harmless nitrogen and water through a chemical reaction, thereby reducing the pollution of the environment by exhaust emissions. However, existing urea feeding methods have many problems, seriously affecting production efficiency and environmental protection. The existing feeding methods have the following drawbacks: ① High labor intensity: The traditional urea feeding process mainly relies on manual handling and feeding. Workers need to frequently carry urea bags weighing tens of kilograms from transport vehicles or warehouses to the feeding port of the denitrification equipment. This process not only consumes a lot of physical strength but also easily leads to worker fatigue and increases labor risks. ② Low work efficiency: Manual handling and feeding are relatively slow, especially when large amounts of urea need to be fed, often requiring multiple workers to work simultaneously to meet production demands; this not only increases labor costs but may also lead to production delays. ③ Serious raw material waste: During manual handling and feeding, urea is easily spilled due to improper operation, causing not only material waste but also potential environmental pollution and increased cleanup costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a urea feeding device for aluminum processing. By optimizing the feeding method, it solves the problems of high labor intensity, low work efficiency and serious waste of raw materials in the prior art, thereby improving work efficiency and reducing the burden on workers.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A urea feeding device for aluminum processing includes a first fixed plate, a second fixed plate, and two support columns. The first fixed plate is located at the left end of each support column, and the second fixed plate is located at the right end of each support column. A displacement frame is slidably connected to the support column via upper and lower guide wheels. A transfer hopper is connected to the lower part of the displacement frame via a lifting mechanism. A positioning nut is located at the top of the displacement frame. The positioning nut is threadedly connected to a lead screw. The left end of the lead screw is connected to a first motor, and the right end of the lead screw is rotatably connected to the second fixed plate. The first motor is fixedly connected to the first fixed plate via a bracket.

[0006] The first fixing plate and the second fixing plate are respectively fixedly connected to the wall above the pin removal equipment by bolts.

[0007] An upper guide wheel is provided above the support column, and a lower guide wheel is provided below the support column. The upper guide wheel and the lower guide wheel are respectively connected to the displacement frame.

[0008] The displacement frame is provided with a lower support at its bottom, and a lifting mechanism is provided on the lower support. The lifting mechanism consists of a winding frame and a second motor. The winding frame is provided on the lower support, and through holes are drilled in the winding frame and the lower support. The second motor is connected to one side of the winding frame through a bracket.

[0009] The transfer hopper is equipped with lifting lugs at the middle of both ends, and the lifting lugs are connected to the pull ropes on the winding frame.

[0010] A screen is provided in the middle of the transfer hopper. An insertion hole is provided on one side of the discharge port at the bottom of the transfer hopper, and a slot is provided on the inner wall of the discharge port.

[0011] The transfer hopper is provided with support legs around its bottom, and the bottom of each support leg is provided with rollers.

[0012] The positive and beneficial effects of this utility model are:

[0013] 1. This utility model ensures that the displacement frame can move smoothly by setting upper and lower guide wheels above and below the support column. With the use of the first motor, the displacement frame can be moved horizontally according to the position of the de-pinning equipment, thereby realizing the rapid transportation of urea.

[0014] 2. This utility model has a winding frame on the lower support and a transfer hopper connected by a pull rope on the winding frame. It can transport urea on the ground and quickly hoist urea to the material inlet of the denitrification equipment. This can effectively shorten the feeding time, improve work efficiency, and reduce the burden on the staff.

[0015] 3. This utility model uses a baffle plate at the bottom of the transfer hopper to open and close the hopper. After the urea is unloaded from the transport vehicle, the workers can quickly place the urea bag on the screen and then use the lifting mechanism to hoist the transfer hopper above the inlet of the denitrification equipment. At this time, the workers stand on the construction platform on one side of the inlet of the denitrification equipment, use tools to cut the urea bag to allow the urea to enter the transfer hopper, and then manually pull the baffle plate out of the slot to allow the urea to quickly enter the denitrification equipment, thus completing the feeding operation and avoiding material spillage. It is convenient to use and simple to operate. Attached Figure Description

A displacement frame 7 is slidably connected to the support column 5 via an upper guide wheel 8 and a lower guide wheel 9. A transfer hopper 15 is connected to the lower part of the displacement frame 7 via a lifting mechanism. A positioning nut 10 is located at the top of the displacement frame 7. The positioning nut 10 is threadedly connected to a lead screw 6. A first motor 4 is connected to the left end of the lead screw 6, and the right end of the lead screw 6 is rotatably connected to the second fixed plate 2.

The lifting mechanism consists of a winding frame 12 and a second motor 14. The winding frame 12 is provided on the lower support 11, and through holes 13 are drilled in the winding frame 12 and the lower support 11. The second motor 14 is connected to one side of the winding frame 12 through a bracket.

[0025] Lifting lugs 16 are respectively provided in the middle of both ends of the transfer hopper 15, and the lifting lugs 16 are connected to the pull rope on the winding frame 12.

[0026] A screen 19 is provided in the middle of the transfer hopper 15. An insertion hole 21 is provided on one side of the discharge port at the bottom of the transfer hopper 15. A slot 20 is provided on the inner wall of the discharge port. An insert plate 22 is inserted into the insertion hole 21 and is located in the slot 20 to close the discharge port. A handle 23 is provided on the outside of the insert plate 22.

[0027] Support legs are provided around the bottom of the transfer hopper 15, and rollers 17 are provided at the bottom of the support legs. The rollers 17 are located below the discharge port of the transfer hopper.

[0028] In the above description, when the transfer hopper is on the ground, the rollers can support the transfer hopper and facilitate the workers to transport urea on the ground.

[0029] In the above description, the first fixing plate and the second fixing plate are respectively fixed above the feed inlet of the de-pinning equipment by bolts.

[0030] In the above description, the displacement frame can move horizontally along the support column under the action of the upper guide wheel and the lower guide wheel; with the cooperation of the first motor, the lead screw and the nut, the displacement frame can move horizontally automatically.

[0033] In use, the entire bag of urea is first transferred to the ground using the transfer hopper. Once the urea is moved to the side of the denitrification equipment, the pull rope is connected to the lifting lug. The transfer hopper is then lifted by the lifting mechanism and moved above the inlet according to the position of the denitrification equipment. Then, the worker cuts open the outer packaging of the urea on the platform to allow the urea to enter the transfer hopper. The worker then manually pulls the insert plate out of the slot to ensure that the urea falls accurately into the inlet of the denitrification equipment. This achieves semi-automation of the feeding process. Workers only need to perform simple operations and do not need to frequently move heavy objects, which significantly reduces labor intensity. It is convenient to use and easy to operate.

[0034] This invention enables both ground transportation of urea and rapid hoisting of urea to the material inlet of the denitrification equipment, achieving semi-automation of the feeding process. Workers only need to perform simple operations, eliminating the need for frequent handling of heavy objects, significantly reducing labor intensity. It is convenient to use, easy to operate, improves work efficiency, and reduces the burden on staff.
