Description

Technical Field

[0001] This utility model relates to the technical field of catalyst production feeding devices, specifically a feeding device for processing polyethylene membrane material catalysts. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) is a polyethylene material with an extremely high molecular weight, typically exceeding 3 million. Due to its unique physical properties, such as extremely high molecular weight, excellent abrasion resistance, impact resistance, and chemical stability, UHMWPE has become an indispensable material in the field of engineering plastics. UHMWPE film materials, due to their superior performance, have been widely used in aerospace, medical equipment, personal protective equipment, and many other fields.

[0003] In the processing of polyethylene catalysts, a feeding device is required. However, existing feeding devices not only cannot control the feeding rate, thus affecting the feeding effect of polyethylene catalysts, but also are prone to blockage in the feeding pipe, which in turn affects the feeding efficiency of polyethylene catalysts.

[0004] For example, the feeding device for processing polyethylene catalyst disclosed in Chinese Patent Publication No. CN220375821U includes a storage tank, a discharge hopper, a semi-cylinder, a feeding roller, a storage bin, a rectangular adjusting frame, a baffle, a servo motor, an elastic actuating plate, and a connecting rod. The servo motor drives the feeding roller to rotate at a constant speed. When the opening of the storage bin rotates upward, the polyethylene catalyst enters the storage bin. When the opening of the storage bin rotates downward, the polyethylene catalyst in the storage bin is discharged, thus enabling continuous feeding. At the same time, the feeding speed can be controlled by controlling the speed of the servo motor. Furthermore, when the feeding roller rotates, the elastic actuating plate can swing left and right past the baffle, which can push the material in the feeding hopper to shake, thereby preventing the material from clogging the feeding hopper and affecting the feeding efficiency.

[0005] The aforementioned feeding device employs a transmission-based feeding method, utilizing the catalyst's own weight to cause it to fall, thus feeding the catalyst into a vertical feeding pipe. A servo motor-controlled baffle is installed inside the feeding pipe to manually control the feeding speed and cause the catalyst to sway. However, the feeding speed of this method is still constrained by the inner diameter of the pipe. If a blockage occurs, a large number of parts need to be disassembled and reassembled to clear the blockage. Furthermore, the industrial production of catalysts requires a batch feeding mode. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a feeding device for processing polyethylene membrane material catalysts, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding device for processing polyethylene film material catalysts, comprising an inclined feeding chute, the top of which is connected to a production component, and the bottom of which is fixedly installed at the top of a feeding seat. The feeding seat has an annular feeding groove, a feeding unit is provided in the feeding groove, and a transmission unit is provided at the end of the feeding seat away from the feeding chute, and a top plate is provided above the transmission unit. The feeding unit includes a rotating shaft, on which a loading seat is fixedly mounted. The loading seat has multiple loading ports arranged in a circular array, and each loading port has a corresponding placement seat welded to it. Each placement seat has an isolation plate welded to both ends. The placement seat and the isolation plate together form a catalyst feeding area. Furthermore, in this application, the catalyst is loaded using an array of loading ports, avoiding blockage problems during the feeding process. The multiple loading ports follow the rotation of the rotating shaft to achieve batch loading of the catalyst, which facilitates subsequent random inspection of the catalyst batch qualification rate. The feeding mode is changed from a completely closed pipeline feeding mode to a semi-open feeding mode, which is suitable for the mass production mode of industrial catalysts.

[0008] A further improvement of this utility model is that: the top of each placement seat is provided with a retractable sponge layer, and the internal cavity of each placement seat is filled with a buffer airbag. Adjacent buffer airbags are respectively connected to a transmission pipe penetrating the placement seat, and one of the buffer airbags is connected to a gas supply pipe penetrating the placement seat. The sponge layer and buffer airbag can reduce the impact force after the catalyst falls, preventing the fixed catalyst from detaching from the loading port under the reaction force. Furthermore, the material feeding trough provided in the material feeding seat of this application has a certain gap distance between its inner wall and the loading seat and the placement seat. Even if the fixed catalyst is not completely fed into the placement seat, it can be collected uniformly in the material feeding trough. A pipe can be added to the bottom of the material feeding trough to collect the detached catalyst.

[0009] A further improvement of the present invention is that: the feeding seat and the top plate provided on one side form a feeding channel, and the feeding seat and the top plate are respectively provided with reinforcing magnets with repulsive magnetic poles.

[0010] A further improvement of this utility model's technical solution lies in the following: an air pump is connected to the end of the gas delivery pipe furthest from the buffer airbag. The air pump is started and controlled by an inductive switch. The air pump and the inductive switch form a closed loop with the reinforcing magnets via wires. It should be noted that in this application, the magnetic field lines between the two reinforcing magnets are cut by the falling catalyst, generating an induced current. Because the air pump and the inductive switch form a closed loop with the reinforcing magnets via wires, the air pump is activated by the generated induced current when catalyst is fed, achieving automatic inflation of the buffer airbag and ensuring stable reception of the catalyst during feeding. As shown in the attached figure, the rotating shaft is directly driven by the motor. Therefore, a further improvement to the above-mentioned closed loop is the addition of a motor starting circuit. After the air pump is started, the motor is turned off; after the air pump is turned off, the motor is driven. In this embodiment, the initial position of the catalyst feeding area formed by the placement seat and its upper insulating plate is located directly below the feeding channel. The start and stop of the motor can be directly controlled manually to ensure that the feeding area is directly below the feeding channel each time it is fed.

[0011] A further improvement of this utility model is that: the transmission unit includes a transmission seat, on which a transmission component is provided, and the top plate is fixedly installed on the transmission seat. The end of the transmission seat near the feeding trough is inclined upwards. A connecting seat is fixedly installed on the top plate, and a rotating shaft is rotatably installed on the connecting seat. A receiving plate in a semi-circular shape is fixedly installed on the rotating shaft. After the rotating shaft drives the loading seat to rotate counterclockwise, the feeding area on it tilts at a certain position, and the loaded catalyst tilts onto the transmission seat. In order to prevent the catalyst from falling off the transmission seat, a receiving plate is set up to transfer the feeding and ensure the stable feeding of the catalyst.

[0012] A further improvement of this utility model is that: multiple sets of damping rods are horizontally arrayed on the receiving plate, and a buffer baffle is fixedly connected to the end of each set of damping rods away from the receiving plate.

[0013] A further improvement of this utility model is that, in order to better concentrate the catalyst in the future, sliding plates are provided on both sides of the transmission seat, and electric push rods are fixedly connected to the two sliding plates respectively, and the sliding plates are slidably connected to the transmission seat. Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are: the loading of catalyst is completed by using the array of loading ports, which avoids the blockage problem during the loading process, and the batch loading of catalyst is achieved by multiple sets of loading ports following the rotation of the rotating shaft, which facilitates the subsequent sampling inspection of the batch qualification rate of catalyst. The loading mode is changed from a completely closed pipeline to a semi-open loading mode, which is suitable for the mass production mode of industrial catalysts.

[0015] The sponge layer and buffer airbags can reduce the impact force after the catalyst falls, preventing the fixed catalyst from falling out of the loading port under the reaction force. In addition, a receiving plate is set up to transfer the material and ensure the stable feeding of the catalyst. Attached Figure Description

[0018] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0019] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0020] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0021] This utility model provides a feeding device for processing polyethylene film material catalysts, including a feeding slide 1 placed at an incline, the top of the feeding slide 1 being connected to a production component, and the bottom of the feeding slide 1 being fixedly installed at the top of the feeding seat 2. The feeding seat 2 has an annular feeding groove 3, and a feeding unit is provided in the feeding groove 3. A transmission unit is provided at the end of the feeding seat 2 away from the feeding slide 1, and a top plate 9 is provided above the transmission unit. The feeding unit includes a rotating shaft 4, on which a loading seat 5 is fixedly installed. The loading seat 5 has multiple loading ports 6 arranged in a circular array, and a corresponding placement seat 7 is welded to each loading port 6. Each placement seat 7 has an isolation plate 8 welded to it at both ends. The placement seat 7 and the isolation plate 8 thereon form the catalyst feeding area.

[0022] Furthermore, in this application, the catalyst is loaded using an array of loading ports 6, avoiding blockage problems during the loading process. Multiple loading ports 6 follow the rotation of the rotating shaft 4 to achieve batch loading of the catalyst, which facilitates subsequent random inspection of the catalyst batch qualification rate. The loading mode is changed from a completely closed pipeline to a semi-open loading mode, which is suitable for the mass production mode of industrial catalysts.

[0023] Example 1: Each placement seat 7 has a retractable sponge layer 10 on top, and each placement seat 7 has a buffer airbag 11 inside the cavity. Adjacent buffer airbags 11 are connected to a transmission pipe 12 that passes through the placement seat 7, and one of the buffer airbags 11 is connected to an air supply pipe 13 that passes through the placement seat 7.

[0024] The sponge layer 10 and buffer airbag 11 provided can reduce the impact force after the catalyst falls, and prevent the fixed catalyst from falling out of the loading port 6 under the reaction force. Furthermore, the feeding trough 3 provided in the feeding seat 2 of this application has a certain gap distance between its inner wall and the loading seat 5 and the placement seat 7. Even if the fixed catalyst is not completely fed into the placement seat 7, it can be collected in the feeding trough 3. A pipe can be added to the bottom of the feeding trough 3 to collect the detached catalyst.

[0025] The feeding seat 2 and the top plate 9 on one side form a feeding channel, and the feeding seat 2 and the top plate 9 are respectively provided with reinforcing magnets 14 with magnetic pole repulsion.

[0026] An air pump 23 is connected to the end of the air supply pipe 13 away from the buffer airbag 11. The air pump 23 is started and controlled by an inductive switch. The air pump 23 and the inductive switch form a closed circuit with the reinforcing magnet 14 through a wire.

[0027] It should be noted that in this application, the magnetic field lines between the two reinforcing magnets 14 are cut by the falling catalyst, generating an induced current. Since the air pump 23 and the induction switch form a closed circuit with the reinforcing magnets 14 through the wires, the air pump 23 is activated by the generated induced current when the catalyst is fed, so as to realize the rapid inflation of the buffer airbag 11 and ensure stable reception when the catalyst is fed.

[0028] As shown in the attached figure, the rotating shaft 4 is directly driven by the motor. Therefore, the further improvement of the above closed loop is the addition of a motor starting circuit. After the air pump 23 is started, the motor is turned off. After the air pump 23 is turned off, the motor is driven. In this embodiment, the initial position of the catalyst feeding area formed by the placement seat 7 and the upper insulating plate 8 is located directly below the feeding channel. The start and stop of the motor can be directly controlled by the user to ensure that the feeding area is located directly below the feeding channel each time the material is fed.

[0029] Example 2: The transmission unit includes a transmission base 15, a transmission component 16 is provided on the transmission base 15, and the top plate 9 is fixedly installed on the transmission base 15. The end of the transmission base 15 near the feeding trough 3 is inclined upward. A connecting seat 24 is fixedly installed on the top plate 9, a rotating shaft 17 is rotatably installed on the connecting seat 24, and a receiving plate 18 in a semi-circular shape is fixedly installed on the rotating shaft 17.

[0030] When the rotating shaft 4 drives the loading seat 5 to rotate counterclockwise, the unloading area on it tilts at a certain position, and the loaded catalyst is poured onto the transfer seat 15. In order to prevent the catalyst from falling off the transfer seat 15, a receiving plate 18 is set up to transfer the unloading and ensure the stable unloading of the catalyst.

[0031] Multiple sets of damping rods 19 are horizontally arranged on the receiving plate 18, and buffer baffles 20 are fixedly connected to the ends of the multiple sets of damping rods 19 away from the receiving plate 18.

[0032] In order to better concentrate the catalyst in the future, sliding plates 21 are provided on both sides of the transfer seat 15, and electric push rods 22 are fixedly connected to the two sliding plates 21 respectively, and the sliding plates 21 are slidably connected to the transfer seat 15.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
