Description

Technical Field

[0001] This utility model belongs to the field of kaolin screening, specifically relating to a kaolin screening and granulation equipment. Background Technology

[0002] Kaolin is an important non-metallic mineral widely used in various industries, such as papermaking, ceramics, rubber, chemicals, coatings, and pharmaceuticals. In these fields, the particle size and morphology of kaolin significantly affect its properties. For example, in the ceramics industry, the particle size determines the product quality and sintering performance; generally, finer kaolin particles are preferred due to better plasticity and higher drying and sintering strength. Therefore, sieving and granulation of kaolin is a crucial pretreatment step aimed at optimizing its particle size distribution to meet the needs of different processes.

[0003] Because kaolin usually contains sandy minerals and other soil components, soil inevitably adheres to the filter screen during the kaolin screening and granulation process, which affects the filtration effect of the filter screen and thus the screening and granulation effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a kaolin screening and granulation equipment, which solves the problems in the existing technology.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A kaolin screening and granulation device includes a base, an open-top box on the top of the base, a filter plate that can be flipped and adjusted at the bottom of the box, and the filter plate can block the bottom of the box; a sliding plate that can be adjusted is provided at the top of the base, and a sliding frame that can slide back and forth is provided at the top of the sliding plate, and the sliding frame is fixed to the box.

[0007] The upper end of the base is provided with a sliding mounting frame, on which multiple spray pipes connected to the pump are installed. The lower end of the spray pipes is connected to a high-pressure nozzle. When the filter plate is flipped to a horizontal position, the high-pressure nozzle can spray water to wash the filter plate and remove the mud and other impurities adhering to its surface, so as to ensure the subsequent screening effect of kaolin.

[0008] Furthermore, a rotating shaft is provided on the filter plate, and the rotating shaft is rotatably connected to the housing.

[0009] Furthermore, a gear is fixed on the rotating shaft, and a rack is slidably connected to the outside of the housing. The rack and the gear mesh with each other. Two first fixing plates are arranged vertically on the outside of the housing. A first lead screw that can rotate is arranged between the two first fixing plates. A connecting plate is arranged on one side of the rack. The first lead screw passes through the connecting plate in the vertical direction and is threadedly connected to it.

[0010] Furthermore, the thread helix angle of the first lead screw is less than the equivalent friction angle.

[0011] Furthermore, when the connecting plate descends to contact the first fixed plate located below, the filter plate flips outward to a horizontal state.

[0012] Furthermore, the sliding frame is slidably connected to the slide plate, a drive motor is fixed at the upper end of the slide plate, a fixed rod is fixed at the end of the drive shaft of the drive motor, a connecting shaft is fixed on the fixed rod, a connecting rod is rotatably connected to the connecting shaft, a connecting seat is provided on the sliding frame, and the connecting rod is hinged to the connecting seat.

[0013] Furthermore, the slide plate is slidably connected to the base, and two second fixing plates are provided at the upper end of the base. A second screw that can rotate is provided between the two second fixing plates. The second screw passes through the slide plate and is threadedly connected to it.

[0014] Furthermore, the thread helix angle of the second lead screw is less than the equivalent friction angle.

[0015] Furthermore, the mounting bracket is slidably connected to the base, and two third fixing plates are provided at the upper end of the base. A rotatable third lead screw is provided between the two third fixing plates, and the third lead screw passes through the mounting bracket and is threadedly connected to it.

[0016] Furthermore, the thread helix angle of the third lead screw is less than the equivalent friction angle.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting a flip-adjustable filter plate at the bottom of the box, the filter plate can be washed while screening is being carried out; and by setting a washing component on the base, when the outer side of the filter plate is flipped to a horizontal position, the high-pressure nozzle in the washing component can wash the surface of the filter plate to remove the mud and other impurities adhering to its surface, so as to ensure the subsequent screening effect of kaolin.

[0019] 2. By incorporating an adjustable sliding plate into the vibration assembly, it is ensured that water stains generated during rinsing do not fall into the collection box and affect the screened material, while also preventing interference between the filter plate and the collection box when the filter plate is flipped.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 and Figure 2 As shown, a kaolin screening and granulation device includes a base 1, a box 2 is provided above the base 1, both the upper and lower ends of the box 2 are open, and a flip-up filter plate 3 is provided at the lower end of the box 2. The filter plate 3 can seal the lower end of the box 2. Kaolin is put into the box 2 and screened through the filter plate 3.

[0029] In this embodiment, as Figure 3 As shown, the filter plate 3 has multiple through holes for filtering and screening kaolin. A rotating shaft 31 is mounted on the filter plate 3, rotatably connected to the housing 2. The rotating shaft 31 is driven to rotate by a flipping drive assembly 4 mounted on the bottom plate, thereby controlling the filter plate 3 to flip and adjust around the shaft 31. During screening, the filter plate 3 blocks the lower end of the housing 2 for screening. After screening, the filter plate 3 can be flipped 180° to a horizontal position facing outwards for easy rinsing and cleaning.

[0030] like Figure 4As shown, the flipping drive assembly 4 includes a gear 41 fixed on the rotating shaft 31, a rack 42 slidably connected to the outside of the housing 2, the rack 42 meshing with the gear 41, two first fixing plates 43 arranged vertically on the outside of the housing 2, a first lead screw 44 rotatably connected between the two first fixing plates 43, a connecting plate 421 on one side of the rack 42, the first lead screw 44 passing through the connecting plate 421 in the vertical direction and threadedly connected to it, by setting a motor on one of the first fixing plates 43 to drive the first lead screw 44 to rotate, the filter plate 3 can be flipped and adjusted around the rotating shaft 31;

[0031] Furthermore, in order to ensure that the filter plate 3 remains stable after the flip position is adjusted, the first lead screw 44 needs to have self-locking properties, that is, the thread helix angle of the first lead screw 44 is less than the equivalent friction angle.

[0032] Furthermore, in this embodiment, when the connecting plate 421 descends to contact the first fixing plate 43 located below, the filter plate 3 just flips outward to a horizontal state, i.e. Figure 2 The state shown.

[0033] Of course, the way to drive the filter plate 3 to rotate around the rotating shaft 31 includes, but is not limited to, the rotation drive component 4 in this embodiment. In other embodiments, the rotating shaft 31 can also be directly driven to rotate by setting a motor on the housing 2, which can also drive the filter plate 3 to rotate around the rotating shaft 31.

[0034] A storage box 7 is provided at the upper end of the base 1, and a vibration component 5 is provided at the upper end of the base 1. The vibration component 5 can drive the box 2 to make reciprocating linear motion, thereby vibrating the kaolin inside the box 2, increasing the screening speed, so that the material screened out in the box 2 can fall into the storage box 7.

[0035] like Figure 5 As shown, the vibration assembly 5 includes a sliding plate 51 that can slide and adjust on the base 1. A sliding frame 52 that can reciprocate is provided on the upper end of the sliding plate 51. The sliding frame 52 is fixed to the box 2. By controlling the reciprocating sliding of the sliding frame 52, the screening can be accelerated. After screening, the sliding plate 51 is controlled to slide away from the storage box 7, and then the filter plate 3 is flipped outward by 180° to facilitate rinsing of the filter plate 3. The rinsing water will not fall into the storage box 7 and affect the screened material. At the same time, it can also prevent the filter plate 3 from interfering with the storage box 7 when it is flipped.

[0036] In this embodiment, as Figure 5As shown, the sliding frame 52 is slidably connected to the slide plate 51. A drive motor 53 is fixed at the upper end of the slide plate 51. A fixed rod 54 is fixed at the end of the drive shaft of the drive motor 53. A connecting shaft 55 is fixed on the fixed rod 54. A connecting rod 56 is rotatably connected to the connecting shaft 55. A connecting seat 521 is provided on the sliding frame 52. The connecting rod 56 is hinged to the connecting seat 521. Under the drive of the drive motor 53, the sliding frame 52 can be driven to slide back and forth.

[0037] In other embodiments, the sliding frame 52 can be directly driven to slide back and forth by fixing a telescopic rod on the slide plate 51.

[0038] Furthermore, in this embodiment, the slide plate 51 is slidably connected to the base 1. Two second fixing plates 11 are provided on the upper end of the base 1. A second lead screw 6 is rotatably connected between the two second fixing plates 11. The second lead screw 6 passes through the slide plate 51 and is threadedly connected to it. By setting a motor on one of the second fixing plates 11 to drive the second lead screw 6 to rotate, the sliding position of the slide plate 51 can be adjusted. In addition, in order to ensure that the sliding position of the slide plate 51 remains stable after adjustment, the second lead screw 6 also has self-locking property, that is, the thread helix angle of the second lead screw 6 is less than the equivalent friction angle.

[0039] In other embodiments, the sliding plate 51 can be directly driven to slide by providing linear drive components such as telescopic rods and cylinders on the upper end of the base 1.

[0040] A rinsing assembly 8 is provided on the upper part of the base 1, such as... Figure 6 As shown, the rinsing assembly 8 includes a sliding mounting frame 81, on which multiple spray pipes 82 are provided. The lower end of each spray pipe 82 is connected to a high-pressure nozzle 83. The spray pipes 82 are connected to a pump. Under the action of the pump, when the outer side of the filter plate 3 is flipped to a horizontal position, the high-pressure nozzle 83 can spray water to rinse the filter plate 3. Moreover, the rinsing process is far away from the collection box 7 to avoid affecting the screened material.

[0041] In this embodiment, the mounting frame 81 is slidably connected to the base 1. The upper end of the base 1 is provided with two third fixing plates 84. A third lead screw 85 is rotatably connected between the two third fixing plates 84. The third lead screw 85 passes through the mounting frame 81 and is threadedly connected to it. By setting a motor on one of the third fixing plates 84 to drive the third lead screw 85 to rotate, the mounting frame 81 can be slidably driven, thereby rinsing the entire surface of the filter plate 3.

[0042] Furthermore, the third lead screw 85 has self-locking properties, meaning that the thread helix angle of the third lead screw 85 is less than the equivalent friction angle, to ensure that the position of the mounting bracket 81 remains stable after adjustment.

[0043] In other embodiments, the mounting bracket 81 can be directly driven to slide by providing linear drive components such as telescopic rods and cylinders at the upper end of the base 1.

[0044] Working principle:

[0045] By installing a flip-adjustable filter plate 3 at the lower end of the housing 2, sieving can be achieved while rinsing the filter plate 3. A rinsing assembly 8 is installed on the base 1. When the filter plate 3 is flipped to a horizontal position, the high-pressure nozzle 83 in the rinsing assembly 8 can rinse the surface of the filter plate 3, removing adhering dirt and other impurities to ensure the subsequent sieving effect of the kaolin. A sliding adjustable slide plate 51 is installed in the vibration assembly 5 to ensure that water generated during rinsing does not fall into the collection box 7 and affect the sieved material, while also preventing interference between the filter plate 3 and the collection box 7 when flipped.
