Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to an integrated device for solid-liquid separation of kaolinite suspension. Background Technology

[0002] In modern industrial production, kaolin, as an important non-metallic mineral resource, is widely used in ceramics, papermaking, chemicals, coatings and other fields. Its quality directly affects the performance and quality of downstream products. Solid-liquid separation, as a key link in the processing and purification of kaolin, is of great significance for improving the purity of kaolin products and reducing production costs.

[0003] Currently, traditional solid-liquid separation of kaolin suspensions mostly employs vertical flow sedimentation tanks. These devices primarily rely on gravity for solid-liquid separation, and their structure typically consists of a central feed pipe and a sedimentation tank. However, this traditional method has many limitations, including low separation efficiency. For kaolin suspensions with fine particle size or high concentration, the particle settling speed is extremely slow, resulting in long processing cycles and limited production capacity. Furthermore, the lack of effective particle agglomeration methods leads to a low probability of particle collisions, making it difficult to form large-diameter flocs and affecting the sedimentation effect. Therefore, we need to upgrade and modify existing technologies to overcome these problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide an integrated solid-liquid separation device for kaolinite suspension to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an integrated solid-liquid separation device for kaolinite suspension, including a vertical flow sedimentation tank, a central feed pipe, a flow guiding component and a drive component. The vertical flow sedimentation tank is provided with a sewage outlet at the bottom and an overflow weir at the top. A water collection tank is provided outside the overflow weir, and water outlets are provided on both sides of the water collection tank. The central feed pipe is located at the upper center of the vertical flow sedimentation tank and is connected to a water inlet pipe on one side.

[0007] The flow guiding component includes a mounting base fixed inside the vertical flow sedimentation tank. A flow guiding plate is fixed to the outer wall of the mounting base. The mounting base and the flow guiding plate are located directly below the central feed pipe. The flow guiding plate is set at an inclined angle and has serrated protrusions on its surface. Multiple sets of ultrasonic oscillators are evenly spaced on the inner wall of the vertical flow sedimentation tank.

[0008] Preferably, the axis of the central feed pipe coincides with the mounting base, and the guide plates are distributed in a ring around the mounting base, with the center of all the guide plates coinciding with the center of the central feed pipe.

[0009] Preferably, the mounting base is provided with a conical top, the center of which corresponds to the lower end of the central feed pipe.

[0010] Preferably, a fixing sleeve is provided on the outside of the central feed pipe, and multiple sets of fixing rods are provided on the outside of the fixing sleeve, the fixing rods being fixed to the inner wall of the vertical flow sedimentation tank.

[0011] Preferably, a spiral sludge discharge machine is connected to the bottom of the sewage outlet, and an output pump is provided on one side of the spiral sludge discharge machine. The spiral sludge discharge machine is a shaftless spiral machine, and the output pump is a screw pump.

[0012] Preferably, the drive assembly includes a lower support fixed to the inner wall of the vertical flow sedimentation tank, a motor is provided at the center of the lower support, a motor frame is provided on the outside of the motor and the motor frame is fixed to the lower end of the lower support, and the drive end of the motor is connected to the bottom of the mounting base.

[0013] Preferably, the lower bracket is provided with a guide groove, and a guide slider is provided in the guide groove. The guide slider is provided in four sets and is fixed at the lower end of the mounting base in a circular array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model has a flow guiding component installed in the device. The flow guiding plate guides the liquid to flow downward in a spiral shape. The serrated protrusions disturb the liquid flow state. The ultrasonic oscillator generates high-frequency mechanical vibration, which destroys the hydration film on the surface of the particles. This can achieve flow guidance and control of the suspension, which can prolong the residence time of the material in the pool and increase the probability of particle settling. At the same time, it can promote the collision between particles, accelerate coagulation, and promote the combination of flocculant and kaolin particles, which can effectively improve the settling efficiency of kaolin particles.

[0016] 2. This utility model has a drive component installed inside the device. The motor drives the mounting base to rotate. The mounting base rotates slowly above the guide slide and the lower support via the guide slider, which in turn drives the guide plate to rotate. This can change the movement trajectory of the fluid and generate a more complex turbulent flow field, thereby accelerating the particle aggregation process, forming larger flocs, improving the settling speed and separation efficiency. At the same time, it prevents excessive particle deposition on the guide plate, avoids clogging of the guide channel, and improves the adaptability of the equipment.

[0026] In this embodiment, the flow guiding component 5 includes a mounting base 51 fixed inside the vertical flow sedimentation tank 1. A flow guiding plate 52 is fixed to the outer wall of the mounting base 51. The mounting base 51 and the flow guiding plate 52 are located directly below the central feed pipe 4. The flow guiding plate 52 is set at an inclined angle and has serrated protrusions 53 on its surface. Multiple sets of ultrasonic oscillators 55 are evenly spaced on the inner wall of the vertical flow sedimentation tank 1. The axis of the central feed pipe 4 coincides with the mounting base 51. The flow guiding plates 52 are distributed in a ring around the mounting base 51, and the center of all the flow guiding plates 52 coincides with the center of the central feed pipe 4. A conical top is provided on the top of the mounting base 51. 54. The center of the conical top 54 corresponds to the lower end of the central feed pipe 4. The conical top 54 guides the suspension to the guide plate 52. The guide plate 52 guides the liquid to flow downward in a spiral shape. The serrated protrusions 53 disturb the liquid flow. The ultrasonic oscillator 55 generates high-frequency mechanical vibration, which destroys the hydration film on the surface of the particles. This can achieve flow control of the suspension, which can extend the residence time of the material in the pool and increase the probability of particle settling. At the same time, it can promote the collision of particles, accelerate coagulation, and promote the combination of flocculant and kaolin particles, which can effectively improve the settling efficiency of kaolin particles.

[0027] In this embodiment, a fixing sleeve 41 is provided on the outside of the central feed pipe 4, and multiple sets of fixing rods 42 are provided on the outside of the fixing sleeve 41. The fixing rods 42 are fixed on the inner wall of the vertical flow sedimentation tank 1.

[0028] In this embodiment, a spiral sludge discharge machine 13 is connected to the bottom of the sewage outlet 11. An output pump 14 is provided on one side of the spiral sludge discharge machine 13. The spiral sludge discharge machine 13 is a shaftless spiral machine, and the output pump 14 is a screw pump.
