Description

Technical Field

[0001] The utility model relates to the technical field of filtering centrifuges, in particular to a filtering centrifuge with an auxiliary feeding function. Background Art

[0002] A filter centrifuge is a device that uses centrifugal force to separate solids from liquids. Its working principle is to use a filter screen and centrifugal force to intercept solid particles in a suspension, while the liquid is discharged through the filter screen. Filter centrifuges are widely used in chemical, pharmaceutical, metallurgical, mineral processing, salt making, light industry, papermaking, food, bioengineering, petrochemical, textile and environmental engineering sectors. For example, in the production process of chili sauce, filter centrifuges play a key role. Since chili sauce contains chili seeds and other solid components, they need to be separated from the liquid matrix. Filter centrifuges can efficiently complete this process.

[0003] After searching, a flip-type filtering centrifuge disclosed in the utility model patent with Chinese patent publication number CN219702272U includes a perforated shell, a self-cleaning impurity mechanism for cleaning the filter cartridge cover is arranged inside the perforated shell, a flip mechanism for flipping the perforated shell is arranged at the bottom of the perforated shell, the self-cleaning impurity mechanism includes a waterproof cover, a first motor is arranged inside the waterproof cover, a driving end of the first motor is fixedly connected to the bottom end of the first support plate, a pushing telescopic machine is fixedly connected to the top end of the first support plate, a pushing end of the pushing telescopic machine is fixedly connected to the bottom end of a circular push plate, a filter cartridge cover is fixedly connected to the top end of the circular push plate, and a brush plate is arranged on the inner wall of the filter cartridge cover. In this utility model, the effect of self-cleaning is achieved, and it is convenient for personnel to disassemble and clean the separated impurities.

[0004] However, there are still areas that need improvement in the above-mentioned flip filter centrifuge. After the material is put into the filter cartridge cover from the inverted hopper, the material will accumulate at the bottom center of the filter cartridge cover, resulting in the filter cartridge cover being heavier at the center and lighter at the area far from the center. This causes the center of mass of the filter cartridge to deviate from the axis of rotation when it rotates, generating an unbalanced torque. As the filter cartridge rotates at a high speed, this imbalance in mass distribution is amplified, causing the filter cartridge to easily vibrate during rotation, thereby causing the entire filter centrifuge to generate greater noise during operation, affecting the production environment. Therefore, a filter centrifuge with an auxiliary feeding function is proposed to solve the above-mentioned problem. Utility Model Content

As a result, when the filter cartridge rotates, its center of mass deviates from the rotation axis, generating an unbalanced torque. As the filter cartridge rotates at a high speed, the imbalance in mass distribution is amplified, making the filter cartridge prone to vibration during rotation, thereby causing the entire filtering centrifuge to generate a large noise during operation, affecting the production environment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 In this embodiment, a filtering centrifuge with an auxiliary feeding function comprises a filtering centrifuge tank 1, a top cover 2 is movably installed on the top of the filtering centrifuge tank 1, a filtering centrifuge mechanism 3 is arranged inside the filtering centrifuge tank 1, and an auxiliary feeding structure 4 is arranged on the top of the top cover 2;

[0025] The filtering centrifugal mechanism 3 includes a limiting ring 301, a filtering centrifugal net frame 302, a connecting block 303, a driving motor 304, a feeding pipe 305 and a discharging pipe 306. The limiting ring 301 is fixedly installed on the inner wall of the filtering centrifugal tank 1, the filtering centrifugal net frame 302 is slidably connected inside the limiting ring 301, the bottom of the filtering centrifugal net frame 302 is fixedly installed with a connecting block 303, the bottom of the filtering centrifugal tank 1 is fixedly installed with a driving motor 304, the top of the top cover 2 is fixedly installed with a feeding pipe 305, and the right side of the filtering centrifugal tank 1 is fixedly installed with a discharging pipe 306;

[0026] The auxiliary feeding structure 4 includes an auxiliary feeding pipe 401, a servo motor 402, a threaded shaft 403, an extrusion plate 404, a limiting shaft 405, an injection pipe 406 and a distribution pipe 407. The auxiliary feeding pipe 401 is movably installed on the top of the feed pipe 305, the servo motor 402 is fixedly installed on the top of the auxiliary feeding pipe 401, the threaded shaft 403 is rotatably connected inside the auxiliary feeding pipe 401, the extrusion plate 404 is threadedly connected outside the threaded shaft 403, the limiting shaft 405 is fixedly installed inside the auxiliary feeding pipe 401, the injection pipe 406 is fixedly installed outside the auxiliary feeding pipe 401, and the distribution pipe 407 is movably installed outside the auxiliary feeding pipe 401.

[0027] Specifically, in the present filtering centrifuge, there are many small holes on the wall of the filtering centrifugal net frame 302, and its inner surface is covered with a filtering cloth. When the driving motor 304 drives the filtering centrifugal net frame 302 to rotate, a huge centrifugal pressure is generated, so that the liquid in the material flows through the filtering cloth and the holes on the wall and is thrown out, while the solid is trapped on the surface of the filtering cloth and the inside of the filtering centrifugal net frame 302.

[0028] Specifically, the distribution pipe 407 is removed from the outside of the auxiliary feeding pipe 401 by rotating the distribution pipe 407, and then the two second screws connected inside the fixed ring outside the auxiliary feeding pipe 401 are removed, and then the entire auxiliary feeding structure 4 is lifted upward, thereby facilitating the removal of the entire auxiliary feeding structure 4 from the filtering centrifuge, and facilitating the cleaning and maintenance of the filtering centrifuge and the auxiliary feeding structure 4.

[0029] In summary, the filtering centrifuge with auxiliary feeding function, through the auxiliary feeding structure 4, after the material enters the interior of the auxiliary feeding pipe 401 through the injection pipe 406, the servo motor 402 drives the threaded shaft 403, so that the extrusion plate 404 slides downward under the guidance of the limit shaft 405, and the extrusion plate 404 is slidably connected with the inner surface of the auxiliary feeding pipe 401, pushing the material into the distribution pipe 407, and the material is evenly scattered and distributed on the inner bottom of the filtering centrifugal net frame 302 through the distribution pipe 407, so that the material will not only accumulate at the center position of the inner bottom of the filtering centrifugal net frame 302, but at the inner bottom of the entire filtering centrifugal net frame 302. The weight of the materials is evenly distributed inside the filter cover, thereby reducing the generation of unbalanced torque, improving the stability of the equipment, reducing noise, and improving the production environment. It solves the problem that after the materials are thrown into the filter cover from the hopper, the materials will accumulate at the bottom center of the filter cover, resulting in the filter cover being heavier at the center and lighter in the area far from the center. This causes the center of mass of the filter cover to deviate from the axis of rotation when it rotates, generating an unbalanced torque. As the filter cover rotates at a high speed, this imbalance in mass distribution is amplified, making the filter cover prone to vibration during rotation, which causes the entire filter centrifuge to generate greater noise during operation, affecting the production environment.
