Description

Technical Field

[0001] This utility model belongs to the field of kaolin processing technology, and in particular relates to a kaolin production equipment for in-situ crystallization catalyst preparation. Background Technology

[0002] Kaolin is a type of clay or clay rock mainly composed of kaolinite group clay minerals. Because it contains magnetic impurities, such as iron and titanium minerals, magnetic separators are needed to remove these impurities during processing. However, the different particle sizes of kaolin particles affect the accuracy of magnetic separation. Therefore, a structure that can classify kaolin particles is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a kaolin production equipment for in-situ crystallization catalyst preparation, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a kaolin production equipment for in-situ crystallization catalyst preparation, including a frame, and further including a sieve frame, a sealing plate and a guide plate. Multiple sieve frames are symmetrically rotatably connected to the frame. The aperture of the sieve holes of the multiple sieve frames decreases sequentially from the upper layer to the lower layer, and the bottom sieve frame has no sieve holes. The sealing plate is set at the opening of the sieve frame, and the guide plate is located below the opening of the sieve frame. The guide plate has protrusions on both sides for covering the two side plates of the sieve frame.

[0005] Beneficial effects

[0006] This invention provides a kaolin production equipment for in-situ crystallization catalyst preparation, which has the following advantages compared with the prior art:

[0007] 1. The user continuously feeds kaolin particles of different sizes mixed together into the screen frame through the feeding port. Then, the user starts the vibrating motors on both sides of the frame. When the eccentric blocks mounted on both ends of the motor's output shaft rotate at high speed, the centrifugal force generated by the eccentric blocks forms a periodic excitation force. This vibration effect is amplified by springs fixed between the frame and the base. At this time, the multiple screen frames inside the frame begin to vibrate reciprocally. Since the screen frames are tilted, the kaolin particles on them move uniformly towards their openings. During this process, particles smaller than the screen aperture will fall into the next screen frame. Because the screen aperture decreases sequentially from top to bottom, this allows for… Each sieve frame intercepts particles larger than its sieve aperture until the bottom sieve frame has no sieve aperture, thus pre-grading the kaolin particles. After sieving, the kaolin particles that meet the requirements are piled on the sealing plate. At this time, the user can turn off the vibration motor and start multiple motors A, so that the lead screw set at the top of the sieve frame starts to rotate at a constant speed, and drives the sliding cylinder connected to it to slide along the length of the connecting plate. This causes the sealing plate to slide synchronously along the length of the sieve frame and start pushing the kaolin particles on it to the other side of the sieve frame. Then the user starts motor A in the opposite direction to reset the sealing plate and starts the vibration motor, so as to sieve the kaolin particles again to reduce the error of the particles.

[0008] 2. After screening, when kaolin of the corresponding particle size is needed, the user can start the corresponding motor to make the screen frame of that layer start to rotate. During the rotation of the screen frame, it gradually separates from the sealing plate, so that the sealing plate stops blocking its opening. When the screen frame overlaps the guide plate, the kaolin particles on it can be poured into the square tube and flow out through the bend at the bottom of the tube. At this time, the particle size error of the particles flowing out is small. After being put into the magnetic separator, it can effectively increase the magnetic separation accuracy.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-3 This invention provides an embodiment of a kaolin production device for preparing an in-situ crystallization catalyst, comprising a frame 101, a sieve frame 201, a sealing plate 202, and a guide plate 203. Multiple sieve frames 201 are symmetrically and rotatably connected to the frame 101. The aperture of the sieve holes in the multiple sieve frames 201 decreases sequentially from the top to the bottom, and the bottommost sieve frame 201 has no sieve holes. The initial position of the sieve frame 201 is in an inclined state. The sealing plate 202 is disposed at the opening of the sieve frame 201. The guide plate 203 is located below the opening of the sieve frame 201, and the guide plate 203 has protrusions on both sides for covering the two sides of the sieve frame 201.

[0016] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sealing plate 202 described in the above embodiments. For example, the sealing plate 202 should be tightly attached to both sides and the bottom plate of the screen frame 201, and a sealing strip should be provided at its connection. The purpose of this setting is to facilitate the increase of the sealing effect of the sealing plate 202 on the screen frame 201 through this setting, thereby preventing particles from falling out from the gaps at its connection when the sealing plate 202 slides.

[0017] Specifically, multiple guide plates 203 are fixedly connected to the grooves of the square tube 204 to guide the particles on the corresponding sieve frame 201 into the square tube 204, and the square tube 204 is fixedly connected to the frame 101.

[0018] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific guide plate 203 described in the above embodiments. For example, the guide plate 203 should be inclinedly arranged on the square tube 204. The purpose of this arrangement is to facilitate the faster sliding of particles from the guide plate 203 into the square tube 204.

[0019] Specifically, one side of each of the multiple screen frames 201 is fixedly connected to the output shaft of the motor 205, and the motor 205 is fixedly connected to the frame 101.

[0020] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motor 205 described in the above embodiments. For example, the motor 205 should be a motor with a self-locking effect. The purpose of this setting is to ensure that when the motor enters the standby state, if an external force is applied to its output shaft, the output shaft can be prevented from reversing.

[0021] Specifically, a lead screw 207 is inclinedly arranged above the screen frame 201, and the inclination angle of the lead screw 207 is the same as the inclination angle of the initial position of the screen frame 201.

[0022] Specifically, the lead screw 207 is rotatably connected to the connecting plate 206, and the connecting plate 206 and the lead screw 207 have the same inclination angle. The connecting plate 206 is fixedly connected to the frame 101. A slide cylinder 208 is threadedly connected to the lead screw 207. The slide cylinder 208 is slidably connected to the connecting plate 206 and is fixedly connected to the sealing plate 202.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific slide cylinder 208 described in the above embodiments. For example, the connection between the slide cylinder 208 and the connecting plate 206 may be provided with a guide groove. The purpose of this setting is to facilitate the increase of the limiting effect on the sliding of the connecting plate 206.

[0024] Specifically, one end of the lead screw 207 is fixedly connected to the output shaft of the motor A209, and the motor A209 is fixedly connected to the connecting plate 206.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 207 described in the above embodiments. For example, the lead screw 207 should be a lead screw with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the slide cylinder 208 connected to it by this setting.

[0026] Specifically, a bent pipe 304 is fixedly connected to the bottom opening of the square tube 204. The bent pipe 304 extends through a groove on one side of the base 301. A feeding port 305 is provided on the frame 101, and the feeding port 305 is located above the side of the screen frame 201 away from its opening.

[0027] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor base 301 described in the above embodiments. For example, the length and width of the groove on one side of the base 301 are both greater than the length and width of the bent tube 304. The purpose of this setting is to leave enough room for the movement of the bent tube 304, thereby avoiding the bent tube 304 from frequently hitting the base 301.

[0028] Specifically, a plurality of springs 302 are fixedly connected between the base 301 and the frame 101, and a vibration motor 303 is fixedly connected to both sides of the frame 101.

[0029] In this embodiment of the invention, the user continuously feeds kaolin particles of different sizes mixed together into the sieve frame 201 through the feeding port 305. The user then starts the vibration motors 303 on both sides of the frame 101. When the eccentric blocks mounted on both ends of the output shaft of the vibration motor 303 rotate at high speed, the centrifugal force generated by the eccentric blocks forms a periodic excitation force. This vibration effect is amplified by the springs 302 fixed between the frame 101 and the base 301. At this time, the multiple sieve frames 201 inside the frame 101 begin to vibrate reciprocally. Since the sieve frames 201 are tilted, the kaolin particles on them move uniformly towards their openings. During this process, particles smaller than the sieve aperture of the sieve frame 201 fall into the next layer of sieve frames 201. Furthermore, since the sieve aperture of the sieve frames 201 decreases sequentially from top to bottom, ... The system enables each sieve frame 201 to intercept particles larger than its sieve aperture until the bottom sieve frame 201 has no sieve aperture, thus pre-grading the kaolin particles. After sieving, the kaolin particles that meet the requirements accumulate on the sealing plate 202. At this time, the user can turn off the vibration motor 303 and start multiple motors A209, which causes the lead screw 207, which is inclined above the sieve frame 201, to start rotating at a constant speed and drive the sliding cylinder 208 connected to it to start sliding along the length of the connecting plate 206. This causes the sealing plate 202 to start sliding synchronously along the length of the sieve frame 201 and to start pushing the kaolin particles on it to the other side of the sieve frame 201. Then, the user can start the motor A209 in the opposite direction to reset the sealing plate 202 and start the vibration motor 303 to sieve the kaolin particles again to reduce particle error.

[0030] After screening, when kaolin of the corresponding particle size is needed, the user can start the corresponding motor 205 to make the screen frame 201 of that layer start to rotate. During the rotation of the screen frame 201, it gradually separates from the sealing plate 202, so that the sealing plate 202 stops blocking its opening. When the screen frame 201 overlaps the guide plate 203, the kaolin particles on it can be poured into the square tube 204 and flow out through the bend 304 at the bottom of the tube. At this time, the particle size error of the particles flowing out is small. After being put into the magnetic separator, the magnetic separation accuracy can be effectively increased.

[0031] 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.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0037] 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.
