Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and more specifically to a vertical centrifuge dehydrator. Background Technology

[0002] In the field of solid-liquid separation, centrifugal dewatering machines are widely used in coal preparation plants and chemical raw material dewatering due to their advantages such as compact structure and large processing capacity. Traditional vertical centrifugal dewatering machines typically use a cylindrical or flat-bottomed dewatering chamber with a vertical or near-vertical cylindrical structure inside. They separate liquids from solid materials through centrifugal force generated by high-speed rotation. However, this design has some drawbacks in practical applications:

[0003] When the cylindrical dewatering chamber rotates at high speed, the material is thrown against the cylinder wall by centrifugal force. However, due to the verticality or insufficient curvature of the cylinder wall, the dewatered solids tend to adhere tightly to the inner wall surface and are difficult to slide off spontaneously. To solve this problem, traditional solutions require mechanical wall scraping structures (such as scrapers, spiral feeders, etc.) to forcibly scrape off the material with external power. However, the introduction of wall scraping structures makes the internal space of the equipment crowded and greatly increases the complexity of the transmission system. At the same time, the frequent friction between the scraper and the cylinder wall leads to rapid wear and tear of the parts, requiring regular replacement, which further increases manufacturing and maintenance costs.

[0004] Therefore, how to provide a vertical centrifugal dewatering machine that utilizes the natural guiding effect of the material's own weight and centrifugal force to achieve efficient discharge and separation under non-scraping conditions is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a vertical centrifugal dehydrator, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vertical centrifugal dewatering machine includes a machine body and a conical dewatering chamber rotatably connected inside the machine body. The top of the conical dewatering chamber has a feed inlet, and its outer side wall has multiple filtrate holes. The bottom wall of the conical dewatering chamber is recessed inward, so that an inclined discharge channel is formed inside the conical dewatering chamber, and a material collection groove corresponding to the feed inlet is formed at the center of the bottom wall of the conical dewatering chamber.

[0008] Through the above technical solution, the vertical centrifugal dewatering machine provided by this utility model, through the conical structure of the conical dewatering chamber, extends the path of the material as it diffuses towards the outer wall under the action of centrifugal force, allowing the liquid in the material to be quickly discharged through the filtration holes on the outer wall, resulting in more thorough separation and achieving solid-liquid separation. At the same time, the inward-curving bottom wall forming an inclined discharge channel allows the material to move smoothly to the bottom using gravity assistance, achieving continuous material discharge without the need for a scraping mechanism, avoiding the material accumulation problem of traditional flat-bottom structures. The setting of the collection groove allows the material to enter the collection groove from the inlet, and under the action of centrifugal force, the material is evenly distributed inside the conical dewatering chamber, improving dewatering efficiency.

[0009] Preferably, in the above-mentioned vertical centrifugal dewatering machine, a feed pipe is provided at the top of the machine body, and the discharge port of the feed pipe extends into the feed inlet. The feed pipe allows the material to enter the feed inlet of the conical dewatering chamber accurately and smoothly, ensuring the accuracy of material feeding, avoiding material residue or spillage on the outside, and improving the efficiency and reliability of material conveying.

[0010] Preferably, in the above-mentioned vertical centrifugal dewatering machine, a central through hole is provided on the top surface of the machine body. The conical dewatering chamber includes a cylindrical section and a conical section. The top of the cylindrical section has the feed inlet, and its top extends through the central through hole to the outside of the machine body. The bottom of the cylindrical section is located inside the machine body. The top of the conical section is fixedly connected to the bottom of the cylindrical section, and its top diameter is smaller than its bottom diameter. The cylindrical section prolongs the material residence time, achieving preliminary solid-liquid separation; the conical section further accelerates liquid discharge through a gradually expanding structure, while guiding solids to slide into the discharge channel; the separate design of the cylindrical and conical sections facilitates manufacturing and maintenance, and the structure with the top protruding from the machine body enhances rotational stability; at the same time, this structural design allows the conical dewatering chamber to rotate stably at high speed inside the machine body, and the central through hole enables communication with the outside, facilitating material input and the overall layout of the equipment.

[0011] Preferably, in the above-mentioned vertical centrifugal dewatering machine, a first bearing is installed inside the central through hole, and the outer wall of the cylindrical section is fixedly connected to the inner ring of the first bearing. The fixed connection between the first bearing installed inside the central through hole and the outer wall of the cylindrical section constrains the radial displacement of the cylindrical section and simultaneously provides stable support for the top of the conical dewatering chamber. This ensures the stability of the conical dewatering chamber during high-speed rotation, reduces vibration and eccentric wear, and improves the operational reliability and service life of the equipment.

[0012] Preferably, in the above-mentioned vertical centrifugal dewatering machine, a drive motor is installed on the top surface of the machine body, and the drive motor is connected to the cylindrical section through a transmission assembly. The transmission assembly (such as a belt or gear) directly drives the conical dewatering chamber to rotate, resulting in low energy loss and fast response speed. This provides power for the high-speed rotation of the conical dewatering chamber, ensuring the efficient operation of the dewatering process. At the same time, the design of the transmission assembly helps to achieve smooth power transmission, improving the operational stability and dewatering effect of the equipment.

[0013] Preferably, the above-mentioned vertical centrifugal dewatering machine further includes a base. The machine body is fixed to the upper surface of the base. A drain outlet is provided on the bottom wall of the machine body, and a drain channel corresponding to and communicating with the drain outlet is provided on the base. A drain pipe is connected to the outlet end of the drain channel. The base provides a stable support foundation for the machine body. The interconnected design of the drain outlet, drain channel, and drain pipe forms a complete drainage path, facilitating the timely and effective discharge of liquid separated during the dewatering process. This avoids the accumulation of liquid inside the equipment, which is beneficial for improving dewatering efficiency and facilitating the cleaning and maintenance of the equipment.

[0014] Preferably, in the above-mentioned vertical centrifugal dewatering machine, a receiving hopper is fixed on the base, and the inlet end of the receiving hopper is correspondingly connected to the outlet of the inclined discharge channel. This corresponding connection ensures that the dewatered solid material can smoothly enter the receiving hopper along the inclined discharge channel, achieving continuous material discharge, facilitating subsequent packaging or transfer, and improving the automation level and work efficiency of material handling.

[0015] Preferably, in the above-mentioned vertical centrifugal dewatering machine, the inlet end of the receiving hopper is located inside the machine body, and the outlet end passes through the base and extends below the base. This design, where the inlet end of the receiving hopper is located inside the machine body and the outlet end extends below the base, not only facilitates the smooth collection and discharge of materials but also effectively prevents external impurities from entering the equipment, ensuring the purity and quality of the dewatered material.

[0016] Preferably, the above-mentioned vertical centrifugal dewatering machine further includes a support assembly, which includes connecting rods, a support rod, and a first bearing. There are two connecting rods, which are arranged obliquely and symmetrically inside the receiving hopper. The bottom ends of the two connecting rods are fixed to the inner wall of the receiving hopper, and their top ends are joined and fixed together. The bottom end of the support rod is fixed to the top ends of the two connecting rods. The second bearing is installed at the top end of the support rod, and its inner ring is fixedly connected to an annular boss extending downward from the bottom wall of the collecting groove. The top first bearing and the bottom second bearing work together to form bidirectional support, distributing the load on the conical dewatering chamber and preventing deformation during high-speed rotation. The oblique connecting rods form a triangular stabilizing structure, enhancing the vibration resistance of the support assembly, reducing eccentric wear, and extending the service life of the equipment.

[0017] Preferably, in the above-mentioned vertical centrifugal dewatering machine, two symmetrically arranged support columns are fixed on the bottom wall of the base. The symmetrically arranged support columns on the bottom wall of the base provide stable support for the base, enhance the structural stability of the entire equipment, enable it to remain stable during operation, reduce vibration and shaking, and improve the safety and reliability of the equipment; the support columns absorb vibration energy through elastic materials or structural design, reduce equipment operating noise, and extend the life of components.

[0018] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a vertical centrifugal dehydrator, which has the following beneficial effects:

[0019] 1. This utility model utilizes the conical structure of the conical dewatering chamber. Under centrifugal force, the material diffuses towards the outer wall, extending its path and allowing the liquid in the material to be quickly discharged through the filtration holes on the outer wall, resulting in more thorough separation and achieving solid-liquid separation. The inclined discharge channel formed by the inward indentation of the bottom wall utilizes gravity to assist the material in moving smoothly towards the bottom wall, achieving continuous material discharge without the need for a scraping mechanism. This avoids the material accumulation problem of traditional flat-bottom structures. The setting of the collection groove allows the material to enter the collection groove from the inlet, and under the action of centrifugal force, the material is evenly distributed inside the conical dewatering chamber, improving dewatering efficiency.

[0020] 2. The first bearing at the top and the second bearing at the bottom of this utility model jointly fix the conical dehydration chamber, forming a double support structure to ensure stable operation during high-speed rotation and reduce vibration and eccentric wear; at the same time, the bottom support rod further distributes the load of the conical dehydration chamber, prevents deformation, and improves the operational reliability and service life of the equipment.

[0039] To further optimize the above technical solution, a collection box is connected to the outlet end of the drain pipe 62, and the liquid collected in the collection box can be processed in the next process.

[0040] To further optimize the above technical solution, a receiving hopper 63 is fixed on the base 6, and the inlet end of the receiving hopper 63 is connected to the outlet 231 of the inclined discharge channel 23.

[0041] To further optimize the above technical solution, the width of the discharge port 231 is the same as the width of the inclined discharge channel 23, and multiple connecting reinforcing ribs 232 are fixed at intervals between the two side walls of the inclined discharge channel 23 (e.g., Figure 3 As shown in the figure, a discharge port 231 is formed between two adjacent connecting reinforcing ribs 232. In this embodiment, there are four connecting reinforcing ribs 232, which are arranged in a cross shape between the two side walls of the inclined discharge channel 23, that is, four discharge ports 231 are formed between the inclined discharge channel 23.

[0047] The embodiments of this utility model are as follows:

[0048] The material enters the inlet 21 of the conical dehydration chamber 2 through the feed pipe 3. Since the top of the cylindrical section 25 of the conical dehydration chamber 2 extends outward through the central through hole on the top surface of the machine body 1, the material can accurately enter the interior of the conical dehydration chamber 2. The drive motor 4 drives the conical dehydration chamber 2 to rotate at high speed through the transmission assembly 5. Under the action of centrifugal force, the material is thrown towards the outer wall of the conical dehydration chamber 2. Due to the special conical structure of the conical dehydration chamber 2, the path of material diffusion to the outer wall is extended, so that the liquid in the material can be quickly discharged through the filtrate hole 22 on the outer wall, realizing solid-liquid separation.

[0049] The liquid separated during the dehydration process is discharged through the filtration holes on the outer wall of the conical dehydration chamber 2, enters the machine body, and then exits the equipment through the drain outlet on the bottom wall of the machine body, the drain channel on the base, and the connected drain pipe, thus preventing the liquid from accumulating inside the equipment.
