Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to an anti-clogging material feeding device. Background Technology

[0002] In the aromatic ketone feeding section, the current operation is as follows: solid material is directly fed into the batching vessel through the manhole. Since the solid material is aluminum trichloride, which is a white crystalline powder soluble in water and alcohol, aluminum trichloride will encounter some problems during storage and use, such as oxidation by air and moisture leading to clumping; aluminum trichloride will be oxidized by water vapor in the air to produce hydrochloric acid and aluminic acid, thus causing clumping; if there are many aluminum trichloride lumps during feeding, the lumps will not dissolve in the vessel and will often block the discharge pipe, affecting production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an anti-blocking material feeding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A material feeding device for preventing blockage includes an outer hopper and an inner hopper located inside the outer hopper. The outer hopper has an outer extension at its outer edge and an inner extension at its inner edge, the outer extension and inner extension being perpendicular to the outer and inner walls of the outer hopper, respectively. The inner hopper has a trumpet-shaped second extension at its top, forming an obtuse angle with the outer wall of the inner hopper. The outer and inner hoppers are coaxially rotatably connected by a bearing, the outer side of which connects to the inner extension of the outer hopper, and the inner side of which connects to the outer wall of the inner hopper. The second extension is located at... Above the inner extension of the outer hopper, several external material holes are provided on the side wall and bottom of the outer hopper, and several internal material holes are provided on the side wall of the inner hopper. Several blades are provided at the bottom of the inner hopper. An annular baffle is connected to the bottom of the outer hopper. A drive motor is installed inside the annular baffle. A gear one is connected to the output shaft of the drive motor. An annular groove is provided at the bottom of the inner hopper. A gear two is connected at the center of the bottom of the inner hopper. The gear one and gear two mesh. The top of the annular baffle is slidably disposed in the annular groove.

[0006] Preferably, a heat dissipation hole is provided at the bottom of the outer hopper on the side of the drive motor inside the annular baffle, and a reserved hole is provided on the outer extension of the top of the outer hopper.

[0007] Preferably, the drive motor is a thin motor.

[0008] Preferably, the size of the inner material hole is greater than or equal to the size of the outer material hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention employs a two-layer filtration system, an outer hopper and an inner hopper, to effectively intercept lumpy aluminum trichloride. The inner hopper can rotate within the outer hopper, and the blades at the bottom can break up the lumpy aluminum trichloride. The aluminum trichloride powder is then fed into the batching vessel through the inner and outer feed holes, preventing lumpy aluminum trichloride from directly entering the batching vessel and clogging the discharge pipe, thus improving production efficiency.

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] like Figure 1-3 As shown, an anti-clogging material feeding device includes an outer hopper 1 and an inner hopper 2 located inside the outer hopper 1. The outer hopper 1 has an outer extension 11 at its outer edge and an inner extension 12 at its inner edge. The outer extension 11 and the inner extension 12 are perpendicular to the outer wall and inner wall of the outer hopper 1, respectively. The outer extension 11 is used to abut against the edge of the feeding port 5 of the batching vessel 4 to provide support.

[0018] The top of the inner hopper 2 is provided with a trumpet-shaped extension 21. The extension 21 forms an obtuse angle with the outer wall of the inner hopper 2. The trumpet-shaped extension 21 facilitates material feeding and prevents spillage.

[0019] The outer hopper 1 and the inner hopper 2 are coaxially rotatably connected by a bearing 3. The outer side of the bearing 3 is connected to the inner extension of the outer hopper 1, and the inner side of the bearing 3 is connected to the outer wall of the inner hopper 2. The outer extension 21 is located above the inner extension of the outer hopper 1 and is used for feeding materials. The side wall and bottom of the outer hopper 1 are provided with a number of outer material holes 13, and the side wall of the inner hopper 2 is provided with a number of inner material holes 22. The size of the inner material holes 22 is greater than or equal to the size of the outer material holes 13, so as to prevent small lumps flowing out of the inner material holes 22 from entering the batching vessel 4 through the outer material holes 13, thus playing a double-layer filtration role.

[0020] The bottom of the inner hopper 2 is equipped with several blades 23, which can crush aluminum trichloride clumps when rotating, thus preventing too many clumps from blocking the inner material hole 22.

[0021] An annular baffle 14 is connected to the bottom of the outer hopper 1. A drive motor 17 is installed inside the annular baffle 14. The output shaft of the drive motor 17 is connected to a gear 18. The annular baffle 14 is set to prevent aluminum trichloride powder from entering the motor, interfering with the motor's operation, damaging the motor, or even causing blockage so that the inner hopper 2 cannot rotate.

[0022] An annular groove 24 is provided at the bottom of the inner hopper 2. A gear 25 is connected at the center of the bottom of the inner hopper 2. Gear 18 meshes with gear 25. The top of the annular baffle 14 is slidably disposed in the annular groove 24, so that the inner hopper 2 can rotate on the annular baffle 14.

[0023] The bottom of the outer hopper 1 on one side of the drive motor 17 inside the annular baffle 14 is provided with a heat dissipation hole 15 for heat dissipation of the drive motor 17. A reserved hole 16 is provided on the outer extension 11 at the top of the outer hopper 1. The wires of the drive motor 17 can be connected from the heat dissipation hole 15 and then pass through the reserved hole 16 to be powered by an external power source. The drive motor 17 is a thin motor, which can save space and make it easier to reduce the size of the device.

[0024] The working principle of this utility model:

[0025] During feeding, the outer hopper 1 is inserted into the feeding port 5 of the batching vessel 4. The outer extension 11 rests against the edge of the feeding port 5 to provide support. The wire of the drive motor 17 is connected through the heat dissipation hole 15 and then passes through the reserved hole 16 to be powered by an external power source. The drive motor 17 is started, and the gear 18 on the motor output shaft rotates, driving the meshing gear 25 to rotate. The gear 25 drives the inner hopper 2 to rotate on the annular baffle 14 through the annular groove 24. The top rotates inside the outer hopper 1 through the bearing 3, feeding aluminum trichloride material into the inner hopper 2 through the outer extension 21. The aluminum trichloride powder flows out through the inner material hole 22 on the side wall under the action of centrifugal force, and then enters the batching vessel 4 through the outer material hole 13 under the action of gravity. The aluminum trichloride clumps are broken up by the rotating blade 23 inside the inner hopper 2 to avoid excessive blockage. The resulting powder flows back into the batching vessel 4.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
