Technical Field

[0001] This utility model relates to the field of feeding device technology, and more specifically, to a feeding device. Background Technology

[0002] A catalyst is a substance that can increase or decrease the rate of a chemical reaction without participating in the reaction itself. Currently, some catalyst raw materials (such as anhydrous copper nitrate) are hygroscopic and readily absorb moisture from the air during storage and transportation, leading to agglomeration and the formation of large clumps. In the process of producing catalysts from these raw materials, they need to be added to the corresponding production equipment via a feeding device. If the agglomerated catalyst raw materials are not treated before being directly added to the production equipment, it is difficult to ensure that the agglomerated catalyst raw materials are broken up, thus affecting subsequent processing. Therefore, improvements are needed. Summary of the Invention

[0036] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0037] The following is in conjunction with the appendix Figures 1-9 This embodiment will be described in further detail.

[0038] Please see Figures 1-5In this embodiment, a feeding device is installed on a storage tank 100 to disperse the catalyst raw materials added to the storage tank 100. A connecting pipe 110 is provided at the upper end face of the storage tank 100. The connecting pipe 110 is fixedly connected to the storage tank 100 by bolts and communicates with the inside of the storage tank 100. A liftable screening hopper 120 is provided on the connecting pipe 110. A first driving component for driving the screening hopper 120 to lift is provided inside the connecting pipe 110. A screen 520 is fixedly connected to the screening hopper 120 by countersunk bolts. A movable crushing component is provided opposite to the screening hopper 120. A second driving component for driving the crushing component to move is provided outside the screening hopper 120.

[0039] In this embodiment, a connecting frame 700 is fixedly connected inside the screening hopper 120, and the screen 520 abuts against the lower side wall of the connecting frame 700; a slot 710 is provided at the bottom of the screening hopper 120, and a locking plate 530 is fixedly connected inside the slot 710 by bolts; a feed hopper 200 is fixedly connected to the upper opening of the screening hopper 120. In actual use, the feed hopper 200 cooperates with the existing feed assembly, wherein the feed assembly includes a conveyor belt 130 arranged opposite to it, one end of which extends to the upper opening of the feed hopper 200. When it is necessary to add catalyst raw materials to the storage tank... When the catalyst raw material is within 100, it is first conveyed to the feed hopper 200 by the conveyor belt 130, so that it is discharged into the screening hopper 120. After being screened by the screen 520, the agglomerated catalyst raw material is intercepted by the screen 520. The crushing component crushes the agglomerated catalyst raw material on the screen 520, reducing its particle size until it can pass through the screen 520. At the same time, the screening hopper 120 can also reciprocate up and down, so that the catalyst raw material gathered on the upper end face of the screen 520 can be turned over, preventing the agglomerated catalyst raw material from clogging the mesh of the screen 520 and ensuring the screening effect of the screen 520.

[0040] The shredder and screen 520 are designed to intercept agglomerated catalyst materials. Smaller catalyst materials will fall directly into the storage tank 100, while agglomerated catalyst materials will accumulate on the upper surface of the screen 520. After being shredded by the shredder, their particle size will be reduced. When the particle size is smaller than the aperture of the screen 520, it will fall into the storage tank 100, thereby reducing the possibility of catalyst agglomeration affecting subsequent processing.

[0041] Combination Figures 1-9 As shown, in this embodiment, a partition 500 is fixedly connected inside the screening hopper 120, and the crushing component includes a pressing plate 510 that is arranged opposite to and movable. The pressing plate 510 is moved to crush the catalyst raw material that is agglomerated at the bottom of the screening hopper 120.

[0042] In this embodiment, the bottom end of the partition 500 extends to the top of the screen 520. The partition 500 divides the interior of the screening hopper 120 into two cavities. The catalyst raw material on the conveyor belt 130 will fall into one of the cavities. When the extrusion plate 510 approaches the partition 500, it will extrude the catalyst raw material and break up the agglomerated catalyst. When the extrusion plate 510 approaches the side wall of the screening hopper 120, it will also extrude the catalyst raw material.

[0043] Specifically, in order to enhance the crushing effect on the agglomerated catalyst, multiple cutters 900 are fixedly connected to both sides of the extrusion plate 510, and the cutters 900 can cut the agglomerated catalyst.

[0044] It should be noted that even when the screening hopper 120 moves to the top, the feed hopper 200 is still located below the conveyor belt 130.

[0045] Combination Figures 1-5 As shown, in this embodiment, a first plate 412 with one end extending through the screening hopper 120 is fixedly connected to the extrusion plate 510. The second driving component includes a mounting plate 400 fixedly connected to the outer wall of the screening hopper 120. The mounting plate 400 is rotatably mounted with a rotating shaft via a bearing. One end of the rotating shaft is fixedly connected to the second plate 410. One end of the second plate 410 is rotatably connected to a third plate 411. One end of the third plate 411 is rotatably connected to the first plate 412. The rotation of the second plate 410 is used to drive the first plate 412 to move back and forth.

[0046] In this embodiment, when the rotating shaft rotates, it can drive the second plate 410 to make a circular motion around the rotating shaft. Since one end of the third plate 411 is rotatably connected to the first plate 412 and the other end of the third plate 411 is rotatably connected to the first plate 412, under the traction of the third plate 411, the first plate 412 can drive the extrusion plate 510 to move back and forth in the screening hopper 120.

[0047] Since one end of the first plate 412 penetrates the side wall of the screening hopper 120, the movement of the first plate 412 is guided, that is, it can only move along the width direction of the screening hopper 120.

[0048] Specifically, a first motor 401 is fixedly connected to one side of the mounting plate 400 by bolts. The output shaft of the first motor 401 is fixedly connected to the rotating shaft, and the power cord of the first motor 401 is electrically connected to the mains power.

[0049] Combination Figures 1-8As shown, in this embodiment, the bottom end of the screening hopper 120 is provided with a slot 710, and a card plate 530 is fixedly connected in the slot 710 by bolts. The first driving component includes a rotating shaft disposed in the connecting pipe 110 and rotatable. The rotating shaft is rotatably installed in the screening hopper 120 through a bearing. A cam 801 is fixedly connected on the rotating shaft. The rotation of the cam 801 is used to push the card plate 530 to drive the screening hopper 120 to move upward.

[0050] In this embodiment, when the rotating shaft rotates, it can drive the cam 801 to rotate accordingly. When the protruding part of the cam 801 contacts the clamping plate 530, it will drive the clamping plate 530 and the screening bucket 120 to move upward. When the cam 801 continues to rotate and its protruding part disengages from the clamping plate 530, the screening bucket 120 will move downward under the action of gravity. This process is repeated continuously, causing the catalyst raw material in the screening bucket 120 to rise and fall back and forth. In order to reduce the possibility of the catalyst raw material falling from the screen 520 contacting the cam 801, the clamping plate 530 is provided with guard plates 531 on both sides corresponding to the position of the cam 801.

[0051] Specifically, a second motor 800 is fixedly connected to the side wall of the connecting pipe 110, the output shaft of the second motor 800 is fixedly connected to the rotating shaft, and the power supply line of the second motor 800 is electrically connected to the mains power.

[0052] Combination Figures 1-3 As shown, in this embodiment, a first connecting plate 300 is fixedly connected to the outer side wall of the screening hopper 120, and a second connecting plate 310 is fixedly connected to the outer side wall of the connecting pipe 110. The second connecting plate 310 is C-shaped, and the bottom end of the second connecting plate 310 is bent to the upper end of the first connecting plate 300. A first bolt 311 is threaded onto the second connecting plate 310, and a spring 312 is sleeved on the first bolt 311. The spring 312 is used to push the first connecting plate 300 to move the screening hopper 120 downward.

[0053] In this embodiment, the second connecting plate 310 is provided with a threaded hole, the first bolt 311 is connected to the threaded hole through the thread, and the spring 312 is sleeved on the first bolt 311 between the first connecting plate 300 and the second connecting plate 310. Under the elastic force of the spring 312, the first connecting plate 300 can drive the screening bucket 120 to move downward continuously, so that the clamping plate 530 always presses against the cam 801.

[0054] Specifically, in order to increase the thrust of the spring 312 on the screening bucket 120, the spring 312, the first connecting plate 300 and the second connecting plate 310 are all provided with multiple sets.

[0055] Combination Figures 1-8 As shown, in this embodiment, a groove 810 is provided on the outer side wall of the connecting pipe 110, and a second bolt 600 with one end extending out of the groove 810 is provided on the outer side wall of the screening hopper 120.

[0056] In this embodiment, the outer wall of the screening bucket 120 is slidably connected to the inner wall of the connecting pipe 110. The outer wall of the screening bucket 120 is provided with a threaded hole 610. One end of the second bolt 600 is threaded into the threaded hole 610. When the lower end of the screening bucket 120 is inserted into the connecting pipe 110, the second bolt 600 can be inserted into the threaded hole 610. Through the cooperation of the sliding groove 810 and the second bolt 600, the screening bucket 120 will not come out of the connecting pipe 110 when it is raised or lowered.

[0057] Specifically, when it is necessary to remove the screen 520 from the screening hopper 120, the second bolt 600 can be turned to disengage it from the threaded hole 610, and then the screening hopper 120 can be moved upward to remove it from the connecting pipe 110. Then the clamping plate 530 can be removed from the clamping groove 710, the countersunk bolt can be removed, the screen 520 can be removed from the screening hopper 120, and the screen 520 can be cleaned.

[0058] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
