Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a white mud dehydration device. Background Art

[0002] White mud, a non-metallic mineral resource, is primarily composed of kaolinite clay minerals and belongs to a class of clays and claystones. Due to its distinctive white appearance and fine texture, it is often referred to as dolomite. White mud is widely used in the production of ordinary Portland cement, alkali-slag bricks, plaster mortar, and in the papermaking industry. It also demonstrates significant potential and application value in flue gas desulfurization, the production of calcium-magnesium fertilizers and soil conditioners, rubber materials, and alkali-slag and padding materials. During the mining process, white mud often carries a significant amount of water, making its transportation and subsequent processing extremely challenging. To ensure its successful application in various fields, a series of processing steps are essential. First, the mined white mud must be properly transported from the mine to the processing site. However, due to its high moisture content, transportation can be prone to various problems, such as increased load on transport vehicles and increased transportation costs. Therefore, dehydration is essential to remove the water content before further processing.

[0003] A dehydrator is disclosed in the patent "Screw Extrusion Dehydrator" (publication number CN209479019U, hereinafter referred to as prior art 1). In prior art 1, a pressure regulating component is used to automatically control the extrusion force of the screw extrusion shaft, thereby effectively dehydrating the material. This pressure regulating component mainly includes a baffle, a cylinder, and a cylinder connecting rod. These components cooperate with each other and work together to enable the baffle to move axially back and forth on the screw extrusion shaft. Through this axial movement, the extrusion force can be precisely adjusted to achieve the best dehydration effect. Specifically, the position adjustment of the baffle is achieved through the coordinated work of the cylinder and the cylinder connecting rod. The piston inside the cylinder reciprocates under the action of air pressure, and this movement is transmitted to the baffle through the cylinder connecting rod, causing it to move axially on the screw extrusion shaft. The range and speed of this movement can be controlled by adjusting the air pressure in the cylinder, thereby achieving fine adjustment of the extrusion force.

[0004] Although the prior art 1 realizes the operation of spiral dehydration, its effect is not good; the spiral diameter of the spiral device in the prior art 1 is constant, resulting in uneven pressure during the extrusion process, and the material cannot obtain a continuously increasing extrusion force during dehydration. This may make it difficult to completely squeeze out some water, especially when dealing with highly viscous white mud, the dehydration effect is not ideal. When the prior art 1 processes highly viscous or slag-containing materials, the space between the spirals is easily blocked, affecting the normal operation of the equipment. The blockage problem may also cause the device to be frequently shut down for manual cleaning, reducing production efficiency. Utility Model Content

[0030] Example 1

[0031] See Figure 1 , the embodiment of the utility model provides a white mud dehydration device. Since some water is often mixed into the white mud during the mining process of the white mud, this will cause the water content of the white mud to be high, making the white mud very inconvenient during transportation. In order to ensure the smooth progress of the transportation process and avoid unnecessary troubles and potential environmental pollution problems, it is usually necessary to take certain measures to deal with the moisture in the white mud. Generally speaking, an effective method is to dehydrate the white mud first. By dehydration, the moisture content in the white mud can be significantly reduced, thereby reducing its weight, reducing transportation costs, and avoiding the phenomenon of wastewater spilling due to excessive water during transportation. This not only improves transportation efficiency, but also effectively prevents the occurrence of environmental pollution. Therefore, dehydrating the white mud before transporting it is an economical and environmentally friendly approach.

[0032] This embodiment describes a white mud dewatering device. Specifically, the device comprises a housing 100 and an extrusion dewatering mechanism 200 disposed within the housing 100. The housing 100 comprises a hollow structure, whose primary function is to accommodate other working components and ensure a smooth dewatering process. Furthermore, the housing 100 is supported by a frame 300, ensuring its stability and durability. The housing 100 is mounted on and supported by the frame 300, ensuring stability during operation and preventing displacement or damage due to vibration or external forces.

[0033] See Figure 2 and Figure 3 In this embodiment, the extrusion dehydration mechanism 200 mainly includes a barrel 210 and a rotating shaft 220 arranged inside the barrel 210. A spiral body 221 with an outer diameter gradually increasing from one end to the other end is provided on the rotating shaft 220. This design forms a material flow cavity 222 between the spiral body 221 and the interior of the barrel 210. A discharge port 211 is provided at one end of the housing 100 connected to the barrel 210, and a feed port 212 is provided at the top of the other end of the barrel 210 so that the material (white mud) can be discharged and entered smoothly. In order to ensure effective drainage during the extrusion dehydration process, a number of leakage holes 213 are also provided on the body of the barrel 210. In addition, a nylon filter cloth 214 is also installed inside the barrel 210 to further improve the dehydration efficiency.

[0034] See Figure 5 The nylon filter cloth 214 is made of nylon fiber, which has excellent wear resistance and tensile strength, and can maintain good filtering performance under high pressure. The nylon filter cloth 214 has a high filtering accuracy, effectively preventing the passage of white mud particles while allowing wastewater to be discharged through the nylon filter cloth 214. This embodiment is particularly suitable for applications with high friction and extrusion strength.

[0035] The extrusion dehydration mechanism 200 is driven by a driving device 400 provided on a frame 300, thereby achieving the extrusion dehydration operation. The spiral body 221 is actually a series of spirally arranged extrusion blades, which exert pressure on the material when the rotating shaft 220 rotates, thereby achieving the purpose of extrusion dehydration.

[0036] Specifically, the material (white mud) enters the interior of the barrel 210 through the feed port 212. When the rotating shaft 220 starts to rotate, the material is squeezed by the spiral 221 and gradually changes from a bulk state to a cake state. In this process, the liquid in the cake material is squeezed out due to the pressure of the spiral 221 and seeps out through the leakage hole 213 on the barrel 210, thereby reducing the moisture content in the cake material. The material is in a continuous squeezing state in the squeezing mechanism, and the operation of the squeezing mechanism is highly automated and the structure is relatively simple. Since the squeezing chamber is basically in a closed state, it pollutes the external environment less. Compared with other dehydration devices, this extrusion dehydration mechanism 200 is more energy-saving and environmentally friendly.

[0037] See Figure 2 During use, after the adjustment drive device 400 is operating normally, the material is evenly added from the feed port 212. The material entering the barrel 210 advances along the axial direction of the rotating shaft 220 under the push of the spiral body 221. During the advancement process, the material is affected by the changing pitch and the inner wall of the adjustment barrel 210, forming a huge extrusion force. This extrusion force causes the material to be mechanically dehydrated under the action of external force, and the moisture is discharged at the drain port 123 through the nylon filter cloth 214. The dehydrated material is finally discharged at the discharge port 211. In order to facilitate the collection of the dehydrated material, the discharge port 211 is also provided with a material receiving box. Furthermore, the nylon filter cloth 214 can be replaced.

[0038] See Figure 3 and Figure 4 , the diameter of the spiral 221 is designed to gradually decrease from the feed port 212 to the discharge port 211. The design of the decreasing spiral diameter gradually increases the pressure on the material during its movement along the barrel 210. As the spiral pitch becomes smaller, the material is continuously compressed, forcing the moisture to be effectively squeezed out, thereby improving the dehydration efficiency. This gradually increasing extrusion force can ensure that the moisture is separated more thoroughly, and is particularly suitable for white mud materials that require efficient dehydration. As the spiral 221 gradually shrinks, the material has a larger space at the front end, which is convenient for smooth feeding and preliminary dehydration. As the material gradually advances to the discharge port 211, the space shrinks, and the increased pressure forces the remaining moisture to be squeezed out. Such a design can reduce the risk of material backflow or blockage, and ensure the continuity and fluidity of the material.

[0039] In this embodiment, the design of gradually increasing the outer diameter of the spiral body 221 is adopted, so that the white mud material is gradually subjected to a greater extrusion force during the dehydration process, thereby achieving a more sufficient dehydration effect and significantly improving the overall dehydration efficiency. Through the combination of the porous water-leaking structure and the built-in nylon filter cloth on the barrel 210, the water generated by the extrusion is quickly discharged to prevent the backflow of accumulated water or the problem of clogging. Compared with traditional equipment, this optimized design improves the drainage speed and filtering effect, prevents the accumulation of white mud residues, and ensures the continuous and efficient operation of the device. In addition, traditional spiral devices are often plagued by blockages, especially when processing highly viscous or particle-rich materials. However, this device effectively intercepts fine particles through nylon filter cloth and maintains good filtration performance under high pressure conditions, significantly reducing the risk of clogging and reducing the frequency of equipment shutdown and manual cleaning.

[0040] In this embodiment, the ends of the barrel 210 are mounted on corresponding positions of the frame 300, and are provided with a first bearing seat 311 and a second bearing seat 312 at these positions. These bearing seats are used to support and secure the ends of the barrel 210, ensuring its stability during operation. Specifically, the first bearing seat 311 is mounted on one end of the frame 300, while the second bearing seat 312 is mounted on the other end of the frame 300.

[0041] See Figure 1 The ends of the rotating shaft 220 are fixedly connected to the first bearing seat 311 and the second bearing seat 312, respectively, to ensure that the rotating shaft 220 can rotate smoothly during operation without shaking or deviating from the predetermined position. This fixed connection method can effectively transmit torque and ensure the stable operation of the entire system.

[0042] The drive unit 400 is located at one end of the barrel 210 on the frame 300. Its main function is to provide power to drive the rotating shaft 220 to rotate. The output shaft of the drive unit 400 is connected to the rotating shaft 220 through a coupling 410, thereby achieving power transmission. The coupling 410 is a common mechanical transmission element that can effectively connect two shafts to ensure that they maintain synchronous rotation during operation, while also absorbing certain vibrations and shocks, improving the stability and reliability of the system. Through this transmission connection method, the drive unit 400 can effectively transmit power to the rotating shaft 220, thereby driving the rotation of the entire barrel 210.

[0043] Among them, the coupling 410 uses a metal elastic coupling 410; the metal elastic coupling 410 is a mechanical device used to connect two shafts and transmit torque. They are designed to provide a certain degree of flexibility and compensation between the shafts to cope with axial, radial and angular deviations caused by factors such as shaft alignment errors, vibrations, and temperature changes. The following are the main features and applications of the metal elastic coupling 410: The metal elastic coupling 410 can compensate for angular deviations, axial displacements, and radial deviations between the shafts. The metal elastic coupling 410 is usually made of metal material and can withstand large torques. And because of the use of metal materials, it also has a long service life and high wear resistance, can absorb and reduce system vibrations and shocks, and protect the transmission system.

[0044] See Figure 1 , an external opening adapted to the feed port 212 is provided at the top of the casing 100. This opening is located at the upper part of the casing 100, ensuring the fit with the feed port 212. Through this opening, a guide hopper 110 is provided on the casing, and its main function is to guide the flow of materials. The guide hopper 110 is connected to the feed port 212, forming a direct passage, so that the material can smoothly enter the interior of the casing 100 from the outside. When the material enters the casing 100 through the feed port 212, the function of the guide hopper 110 is to ensure that the material can be smoothly introduced into the interior of the barrel 210, thereby preparing for the subsequent extrusion operation process. The setting of the guide hopper 110 not only improves the efficiency of material transmission, but also ensures the stability and accuracy of the material during the transmission process, thereby improving the working performance of the entire equipment.

[0045] See Figure 2 Several support plates 215 are also provided on the outside of the barrel 210, evenly spaced around it. Each support plate 215's ends are tightly connected to the top and bottom of the housing 100, ensuring the stability and robustness of the entire structure. This arrangement not only increases the barrel's 210's load-bearing capacity but also effectively prevents deformation or damage during use. This spacing of support plates 215 significantly increases the service life of the entire device and provides a safer and more reliable working environment for operators.

[0046] A deflector is also installed at the bottom of the housing 100. The deflector is designed to better guide and control the flow of fluid, thereby improving the performance and efficiency of the device. Specifically, the deflector is tilted at a pre-set angle to effectively guide the fluid along a specific path.

[0047] See Figure 2The deflectors include a first deflector 121 and a second deflector 122. These two deflectors are arranged in a symmetrical structure to ensure uniform and balanced flow of the fluid within the housing 100. This symmetrical design prevents unnecessary turbulence or eddies within the housing 100, thereby reducing energy loss and improving overall fluid control.

[0048] The first and second guide plates 121, 122 are tilted so that their distal ends are positioned lower. Drain ports 123 are specifically positioned at these distal ends to facilitate the drainage of fluid from the interior of the housing 100. The design of these drain ports 123 allows for smooth drainage of fluid, avoiding any obstruction or blockage during the drainage process.

[0049] In order to further ensure the effective discharge of the fluid, the bottom of the drain port 123 is also equipped with a liquid collecting tank 124. The function of the liquid collecting tank 124 is to collect the fluid discharged through the drain port 123 to prevent the fluid from overflowing outside the casing 100 or causing environmental pollution. The design of the liquid collecting tank 124 takes into account sufficient capacity and reasonable structure to ensure that the discharged fluid can be efficiently collected and stored until they are properly processed or discharged. In general, the guide plate effectively improves the flow control and discharge efficiency of the fluid inside the casing 100 through its angle setting, symmetrical structural design, and the configuration of the terminal drain port 123 and the liquid collecting tank 124, thereby providing a strong guarantee for the overall performance and reliability of the equipment.

[0050] Example 2

[0051] See Figure 2 、 Figure 3 and Figure 5 The present invention provides a white mud dewatering device. In Example 1, a dewatering device for white mud is provided by spiral extrusion. However, during the extrusion, the fluid material carrying water does not fill the entire screw groove, and the flow state in the rotating shaft 220 is relatively free, mainly flowing forward under the drag of the barrel 210. Under certain conditions (such as when the water content is too high and the viscosity of the material is very low), the material may flow back from the gap between the screw rib and the barrel to the feeding end due to the front pressure and gravity. If the backflow flow is too large, the material will not be able to be transported forward normally and the dehydration operation cannot be carried out. Since the material has not yet completely filled the screw groove, the material flow has not fully developed. The drag effect of the barrel 210 on the material is mainly used to promote the forward flow of the material and provide pressure for the material. Therefore, in the unfilled section, the material in the screw groove has no seepage caused by pressure except for the seepage to the outside of the barrel caused by its own gravity, which may result in the discharged material still containing a lot of water. Therefore, in this embodiment, a baffle 131 is provided to help the material be squeezed and compacted.

[0052] See Figure 2 The baffle plate 131 is mounted on the rotating shaft 220 near one end of the discharge port 211. The baffle plate 131 is sized to completely cover the discharge port 211, trapping the material within the barrel 210 and preventing it from exiting. A through-hole is provided in the middle of the baffle plate 131. The diameter of this through-hole is larger than that of the rotating shaft 220, allowing the baffle plate 131 to be smoothly mounted on the rotating shaft 220. To ensure that the baffle plate 131 can rotate flexibly on the rotating shaft 220, a certain distance is left between the two.

[0053] A pair of telescopic cylinders 132 are installed within the housing 100 near the discharge port 211. These cylinders 132 are located on either side of the material retaining plate 131, ensuring symmetry and uniform force distribution. The piston rod 133 of each telescopic cylinder 132 is securely connected to both ends of the material retaining plate 131, ensuring synchronized movement between the two.

[0054] By controlling the telescopic movement of the piston rod 133 on the telescopic cylinder 132, the gap between the material retaining plate 131 and the discharge port 211 can be precisely adjusted. During the production process, if the material's moisture content is too high, resulting in a very low viscosity, the material retaining plate 131 can completely close the discharge port 211. This allows the material to be extruded and piled up inside the barrel 210, effectively enhancing the dehydration effect of the extrusion. This arrangement not only improves production efficiency but also ensures the quality of material handling, making the entire production process smoother and more efficient.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
