Description

Technical Field

[0001] This utility model relates to the field of catalyst crushing and sorting equipment, specifically a multi-category catalyst crushing and sorting equipment. Background Technology

[0002] Catalyst crushing and sorting equipment is a device that crushes block catalysts and then screens them using a linear vibrating screen. The crushing process involves crushing the catalyst with a jaw crusher and then using a linear vibrating screen to separate the catalyst into coarse, medium, and fine particles through vibration.

[0003] However, while the linear vibrating screens used in current catalyst crushing and sorting equipment perform well in terms of quality and efficiency when processing a single type of catalyst, they exhibit significant limitations when the production process requires frequent switching of catalyst types. Due to the diverse physicochemical properties of catalysts, such as significant differences in particle size distribution, density, adhesion, and chemical activity, the screening machine is prone to leaving powdery residues of previously processed catalysts when changing catalyst types. This can lead to the destruction or alteration of the active components of the new catalyst, significantly reducing its catalytic performance and affecting the quality of the final product and production efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multi-category catalyst crushing and sorting equipment to solve the technical problem that existing linear vibrating screens are prone to leaving powdery residues when frequently switching between different types of catalysts, which leads to the contamination or destruction of the active ingredients of the new catalyst, thereby affecting product quality and production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-category catalyst crushing and sorting device, including a sorting device, the sorting device including a sorting table, a maintenance mechanism provided on the top of the sorting table, the maintenance mechanism including a mounting frame, a lead screw seat provided at the bottom of the mounting frame, the lead screw seat being located directly above the sorting trough, a lead screw being provided inside the lead screw seat, and a lead screw slider being engaged on the lead screw, a mounting plate being screwed to the bottom of the lead screw slider, a plurality of wiping wheels being mounted on the bottom of the mounting plate, and a plurality of second servo motors being provided on the top of the mounting plate, and the output ends of the plurality of second servo motors being fixedly connected to the wiping wheels;

[0006] The front end of the lead screw holder is provided with a first servo motor, and the output end of the first servo motor is fixedly connected to the lead screw inside the lead screw holder.

[0007] By adopting the above technical solution, the wiping wheel is precisely positioned in three dimensions above the sorting tank through a servo motor-driven screw-slider mechanism. Combined with independent control of multiple motors, the cleaning module's adaptive coverage capability for complex tank structures is ensured.

[0008] Furthermore, the wiping wheel is made of sponge and is used to clean the sorting tank.

[0009] By adopting the above technical solution, the sponge-material wiping wheel provides flexible contact during the cleaning process, avoiding damage to the surface of the sorting tank, while efficiently adsorbing residual micro powder.

[0010] Furthermore, the sorting table has a sorting trough inside, a filter screen is installed at the bottom inside the sorting trough, and a coarse screen outlet is provided at one end of the sorting trough.

[0011] By adopting the above technical solution, the sorting tank integrates the filter screen and the coarse screen outlet in a stepped layout, optimizing the material sorting path and simultaneously completing fine grading and residue collection.

[0012] Furthermore, the bottom of the sorting station is provided with four support legs, and the four support legs are arranged in a rectangular array.

[0013] By adopting the above technical solution, the four-leg rectangular array arrangement provides a statically indeterminate support structure, effectively suppressing the transmission of sorting vibration.

[0014] Furthermore, two vibration motors are mirror-mounted on both sides of the sorting table along the center line of the width of the sorting table.

[0015] By adopting the above technical solution, the symmetrically arranged vibration motor excites linear unidirectional vibration waves, thereby enhancing the efficiency of catalyst particle diffusion and sieving.

[0016] Furthermore, the mounting bracket is detachably fixed to the top edge of the sorting table by bolts.

[0017] By adopting the above technical solution, the bolt-fixed mounting bracket enables quick disassembly and assembly of the maintenance mechanism, facilitating system upgrades and component replacement.

[0018] Furthermore, a rotation adjustment mechanism is provided between the lead screw slider and the mounting plate to adjust the tilt angle of the wiping wheel.

[0019] By adopting the above technical solution, the rotary adjustment mechanism enables the wiping wheel to have dynamic tilt angle compensation capability, which can meet the cleaning needs of complex curved surfaces in the sorting tank.

[0020] Furthermore, the inner wall of the sorting tank is provided with a wear-resistant liner, which is detachably connected to the inner wall of the sorting tank.

[0021] By adopting the above technical solution, the detachable wear-resistant liner provides a customized protective layer for the sorting tank, expanding the material compatibility of the equipment.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model achieves comprehensive, automated, and deep cleaning of the inner wall of the sorting tank, the surface of the filter screen, and the corner gaps by setting up a maintenance mechanism in which the first servo motor controls the lead screw slider and cooperates with the second servo motor to drive the multi-angle adjustable wiping wheel. The sponge material wiping wheel ensures gentle and efficient adsorption of residual powder, completely eliminating the risk of physical cross-contamination between different types of catalysts, ensuring the purity of the active ingredients of the new catalyst from the source. Moreover, the detachable mounting bracket transforms the originally time-consuming and laborious manual cleaning into one-button automated operation. During the production gap when switching catalyst types, the system can efficiently complete the cleaning task, minimize equipment downtime, avoid the safety and cleanliness risks of manual operation, and significantly improve the flexibility and overall efficiency of multi-variety, small-batch production mode.

[0024] 2. This utility model sets up a sorting trough and a wear-resistant liner. The wear-resistant liner can be quickly replaced with a matching material according to the characteristics of the catalyst being processed. This not only greatly extends the life of the core sorting chamber, but also provides a smooth and easy-to-maintain working surface for deep cleaning, significantly reducing the maintenance cost of the equipment throughout its entire life cycle.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1:

[0032] A multi-category catalyst crushing and sorting equipment, such as Figure 1-4 As shown, the system includes a sorting device 1, which includes a sorting table 101. A maintenance mechanism 2 is provided on the top of the sorting table 101. The maintenance mechanism 2 includes a mounting frame 201. A lead screw seat 202 is provided at the bottom of the mounting frame 201. The lead screw seat 202 is located directly above the sorting trough 103. A lead screw is provided inside the lead screw seat 202, and a lead screw slider 204 is engaged on the lead screw. A mounting plate 205 is screwed to the bottom of the lead screw slider 204. Multiple wiping wheels 207 are installed at the bottom of the mounting plate 205. Multiple second servo motors 206 are provided on the top of the mounting plate 205, and the output ends of the multiple second servo motors 206 are fixedly connected to the wiping wheels 207.

[0033] A first servo motor 203 is provided at the front end of the lead screw seat 202, and the output end of the first servo motor 203 is fixedly connected to the lead screw inside the lead screw seat 202. The first servo motor 203 drives the lead screw inside the lead screw seat 202 to rotate, which drives the lead screw slider 204 to move precisely and linearly above the sorting tank 103. At the same time, multiple sets of second servo motors 206 provided at the bottom of the mounting plate 205 independently control the rotation of the wiping wheel 207 to form a three-dimensional spatial motion trajectory, thereby achieving all-round dynamic cleaning coverage of the complex inner cavity of the sorting tank 103.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The wiping wheel 207 is made of sponge and is used to clean the sorting tank 103. The wiping wheel 207, which is made of sponge, produces elastic deformation when rotating and cleaning, and closely fits the inner wall of the sorting tank 103 and the surface of the filter screen 104. While removing residual particles of catalyst, it avoids scratches on the equipment surface caused by hard metal contact, and its porous structure significantly improves the adsorption capacity of micro powder.

[0035] See Figure 1 , Figure 2The sorting table 101 has a sorting tank 103 inside, and a filter screen 104 is installed at the bottom of the sorting tank 103. A coarse screen outlet 105 is opened at one end of the sorting tank 103. The filter screen 104 at the bottom of the sorting tank 103 forms a primary sorting zone. Together with the coarse screen outlet 105 at the end, it forms a stepped screening channel, so that the catalyst particles can be finely screened and large particle residues can be directionally discharged under the action of vibration, realizing the multi-stage separation efficiency in a single sorting process.

[0036] See Figure 1 , Figure 2 The bottom of the sorting table 101 is provided with four support legs, which are arranged in a rectangular array. The four support legs arranged in a rectangular array constitute a statically indeterminate support system. By increasing the contact stability base point between the equipment and the ground, the intensity of the transmission of high-frequency mechanical vibration generated by the vibration motor 102 to the external environment during the operation of the sorting table 101 is significantly reduced.

[0037] See Figure 3 , Figure 4 Two vibration motors 102 are mirror-arranged on both sides of the sorting table 101 along the center line of the width of the sorting table 101. The two vibration motors 102 mirror-arranged along the center line of the width of the sorting table 101 synchronously generate in-phase excitation force, forming a uniformly distributed linear vibration wave field in the sorting tank 103, which promotes the efficient chromatographic dispersion and sieving of catalyst particles of different sizes.

[0038] Example 2:

[0039] See Figure 1 , Figure 2 The mounting bracket 201 is detachably fixed to the top edge of the sorting table 101 by bolts. The mounting bracket 201 is detachably connected to the top edge of the sorting table 101 by bolts, so that the entire maintenance mechanism 2 has modular installation characteristics. It can be quickly disassembled as a whole when the equipment is maintained or the function is upgraded, reducing the complexity of maintenance operations.

[0040] See Figure 3 , Figure 4 A rotary adjustment mechanism is provided between the lead screw slider 204 and the mounting plate 205 to adjust the tilt angle of the wiping wheel 207. The rotary adjustment mechanism provided between the lead screw slider 204 and the mounting plate 205 supports the real-time adjustment of the contact angle between the wiping wheel 207 and the inner wall of the sorting tank 103 during the three-dimensional movement, especially ensuring the close cleaning effect on the corners and non-planar areas of the tank.

[0041] See Figure 1 , Figure 2The inner wall of the sorting tank 103 is provided with a wear-resistant liner. The wear-resistant liner is detachably connected to the inner wall of the sorting tank 103. The inner wall of the sorting tank 103 is equipped with a detachable wear-resistant liner. Different protective layers of different materials can be selected according to the abrasion characteristics of the catalyst being processed. This reduces the wear of the tank body and provides chemical resistance for the sorting of highly corrosive catalysts.

[0042] The implementation principle of this embodiment is as follows: First, the operator turns on the vibration motor 102. The vibration motors 102, which are symmetrically arranged on both sides of the sorting table 101, synchronously generate linear vibrations of the same phase, which causes the catalyst particles in the sorting tank 103 to achieve chromatographic diffusion on the surface of the filter screen 104. Particles with qualified particle size pass through the filter screen 104 to complete the collection, while coarse particles are conveyed by vibration and directionally discharged from the coarse screen outlet 105.

[0043] After the sorting operation is completed, start maintenance mechanism 2:

[0044] Positioning drive: The first servo motor 203 drives the lead screw inside the lead screw seat 202 to rotate, which in turn drives the lead screw slider 204 to move precisely along the length of the sorting groove 103;

[0045] Three-dimensional cleaning: The mounting plate 205 at the bottom of the lead screw slider 204 is equipped with multiple sets of wiping wheels 207. Each wiping wheel 207 is driven to rotate by an independent second servo motor 206. At the same time, the rotation adjustment mechanism dynamically adjusts the tilt angle of the mounting plate 205 so that the sponge material wiping wheel 207 closely fits the inner wall of the sorting tank 103, the surface of the filter screen 104 and the corner areas.

[0046] Adsorption of residue: The wiping wheel 207 undergoes elastic deformation during rotation, and efficiently adsorbs residual catalyst powder through its porous structure;

[0047] Module maintenance: The detachable mounting bracket 201 supports the overall disassembly and maintenance mechanism 2, and the wear-resistant lining plate on the inner wall of the sorting tank 103 can be replaced as needed to adapt to different catalyst characteristics;

[0048] Vibration damping support: The rectangular array of four support legs at the bottom of the sorting table 101 forms a statically indeterminate support structure, which continuously suppresses vibration transmission.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
