Description

Technical Field

[0001] This utility model relates to a thickener, and more particularly to an inclined tube thickener. Background Technology

[0002] Thickeners (also known as bulking machines) are key pieces of equipment in the mining, metallurgical, chemical, and environmental protection industries. They are mainly used for solid-liquid separation, concentrating solid particles in slurry through gravity sedimentation and discharging them as a high-density underflow, while simultaneously recovering the clarified liquid. Their operational stability directly affects production efficiency, resource recovery rate, and operating costs.

[0003] In conventional inclined plate thickeners, small particles adhere to the surface of the inclined plates during the process of passing through the packing material. Over time, this accumulation of particles clogs the flow area of ​​the plates, making cleaning extremely difficult. Therefore, a common method is to empty the sedimentation tank during maintenance or temporary shutdowns and thoroughly flush and clean the accumulated sludge inside the inclined plates with high-pressure water to eliminate the blockage caused by sludge. However, frequent cleaning disrupts normal operation, resulting in long work cycles and a heavy workload. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an inclined tube thickener with a compact structure that can effectively clean small particles on the inclined plate to ensure the overall solid-liquid separation efficiency.

[0005] This utility model provides an inclined tube thickener, which includes a tank body 11, a central well 4, an inclined plate 7, and a rake mechanism. The tank body 11 has a working chamber formed within it. The central well 4 is disposed within the working chamber and coaxial with it. A gap exists between the lower end of the central well 4 and the bottom surface of the working chamber, forming a settling zone. The rake mechanism includes a rake 31 rotatably mounted within the working chamber for scraping sediment from the bottom of the working chamber, and a drive device 32 for driving the rake 31 to rotate. An inclined plate is formed between the outer wall of the central well 4 and the inner wall of the working chamber. The inclined plate 7 is a plurality of inclined plates and is set in the inclined plate installation area by elastic elements. Each inclined plate 7 is equipped with a vibration motor 8. By using multiple independent inclined plates 7 and an independent vibration motor 8 on each inclined plate 7, each inclined plate can vibrate independently. Through the vibration of the vibration motor, small particles can be effectively prevented from adsorbing and accumulating on the surface of the inclined plate, ensuring smooth water flow and avoiding small particles from being attached to the surface of the inclined plate for a long time, which would reduce the water flow area or even cause blockage. This ensures the water flow area and concentration efficiency, so there is no need to stop the machine for cleaning, which greatly improves the concentration efficiency and reduces cleaning and maintenance costs.

[0006] Furthermore, the vibration motor 8 is located on the top of the inclined plate 7; this facilitates the installation of the vibration motor 8 and ensures that the vibration motor 8 is above the water surface, preventing sewage from submerging the vibration motor and affecting its normal operation. This facilitates installation and maintenance and ensures overall operational stability and reliability.

[0007] Furthermore, the elastic element is a spring and / or rubber, which elastically connects the inclined plate 7 to the pool body 11, preventing the generated vibration from being transmitted to the adjacent inclined plate 7 or the pool body 11, avoiding resonance, ensuring that each inclined plate vibrates independently, effectively isolating the impact of vibration, ensuring the stability of the overall structure, extending the service life of the equipment, and improving operating efficiency.

[0008] Furthermore, the multiple inclined plates 7 are arranged in a ring array within the inclined plate installation area. Preferably, they are evenly distributed circumferentially, i.e., set at equal angles. This can increase the filtration area of ​​the inclined plates 7, thereby improving the concentration efficiency. On the other hand, it can make the whole structure balanced, ensuring uniform force distribution and overall reliability and stability.

[0009] Furthermore, each of the aforementioned vibration motors 8 can achieve independent vibration, sequential vibration, or group vibration. Through different vibration modes, vibration can be performed according to different working conditions, thereby improving cleaning efficiency and ensuring the overall concentration efficiency of the thickener.

[0010] Furthermore, the central well 4 is equipped with a feed pipe 5, the feed direction of which is tangential to the inner wall of the central well 4; the wastewater entering tangentially passes through the inner wall of the central well 4 and then enters the tank 11 after achieving a stable flow, thus avoiding impact on the solution in the tank and affecting the concentration, and ensuring the efficiency and effect of concentration.

[0011] Furthermore, a support frame 9 is fixed in the installation area of ​​the inclined plate 7, and the inclined plate 7 is installed on the support frame 9 by means of elastic elements; the support frame 9 is also used to fix the central well 4 in the center of the pool and to serve as the installation carrier of the inclined plate 7, which facilitates the overall installation of the central well and the inclined plate, and has high support strength and good strength.

[0012] Furthermore, the length direction of the inclined plate 7 is parallel to the radial direction of the working chamber; this can effectively increase the number of inclined plates 7 installed per unit area, increase the filtration area, and thus improve the concentration efficiency.

[0013] Furthermore, the vibration motor 8 is located at one end near or away from the central well 4; this allows the vibration motor to be close to the end of the inclined plate 7, generating asymmetrical vibration and easily exciting lateral vibration, which helps the inclined plate 7 to shake off the attached particles on its surface, resulting in a good cleaning effect.

[0014] Furthermore, the vibration amplitude and vibration frequency of the vibration motor 8 are adjustable. By using different vibration amplitudes and frequencies, it can adapt to different usage scenarios, providing high flexibility, good cleaning effect, and effectively ensuring separation efficiency.

[0015] This utility model of an inclined tube thickener features independent inclined plates and independent vibration motors, allowing each inclined plate to vibrate independently. This effectively prevents small particles from adsorbing and accumulating on the inclined plate surface, ensuring smooth water flow and avoiding the reduction or even blockage caused by long-term adhesion of small particles to the inclined plate surface. This ensures the water flow area and separation efficiency, eliminating the need for machine shutdown for cleaning, significantly improving separation efficiency and reducing cleaning and maintenance costs. The vibration motors operate independently with different working modes, allowing for targeted cleaning or full coverage, resulting in good cleaning effect and high flexibility. The vibration amplitude and frequency of the vibration motors are adjustable, adapting to different material characteristics, achieving efficient cleaning and equipment protection, and improving overall operating efficiency. The optimized installation position of the vibration motors generates asymmetrical vibration and easily induces lateral vibration, facilitating the removal of adhering particles from the inclined plate surface, resulting in good cleaning effect. This utility model of an inclined tube thickener has a compact structure, self-cleaning function, and good cleaning effect, ensuring long-term stable operation of the equipment, reducing maintenance frequency, extending service life, and improving the overall efficiency of the water treatment system.

[0018] Figure 3 for Figure 1 Enlarged view of section A. Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] See Figures 1-3 This utility model provides an inclined tube thickener, which includes a pool body 11, a central well 4, an inclined plate 7, and a rake mechanism. The pool body 11 is a cylindrical shape with an open upper end and its axis is perpendicular to the ground. A working chamber is formed inside the pool body 11. The working chamber is cylindrical and its bottom surface is a conical structure, specifically a conical structure that is larger at the top and smaller at the bottom to facilitate material discharge. A discharge port is provided at the bottom of the working chamber.

[0021] The central well 4 is a cylindrical structure, coaxial with the working chamber. It is located within the working chamber, at a relatively high position, and is primarily used for feeding. A feed pipe 5 is installed within the central well 4, its feeding direction tangential to the inner wall of the central well 4. Wastewater entering tangentially flows steadily through the inner wall of the central well 4 before entering the tank 11. This eliminates the impact force at the outlet of the feed pipe 5, preventing disturbance to the liquid within the tank and ensuring the stability of the separation process, thus improving separation efficiency and effectiveness. A gap exists between the lower end of the central well 4 and the bottom surface of the working chamber, forming a settling zone.

[0022] The scraper mechanism includes a scraper 31 and a drive device 32. The scraper 31 is equivalent to a scraper and is rotatably mounted in the working chamber via a scraper shaft 33. It is used to scrape off the sediment at the bottom of the working chamber. The scraper shaft 33 is vertically arranged and coaxial with the central well. A truss is provided at the top of the pool body 11. The drive device 32 is mounted on the truss and connected to the scraper shaft 33 to drive the scraper 31 to rotate, thereby scraping the material at the bottom of the settling zone. The drive device 32 is a drive motor.

[0023] An inclined plate installation area is formed between the outer wall of the central well 4 and the inner wall of the working chamber for installing inclined plates 7. Each inclined plate 7 consists of multiple inclined tubes, typically 15-25 in number. These inclined plates are set within the inclined plate installation area via elastic elements. Each inclined plate 7 is equipped with a vibration motor 8. The use of multiple independent inclined plates 7, each with its own vibration motor 8, allows each inclined plate to vibrate independently. The vibration of the motors effectively prevents small particles from adsorbing and accumulating on the inclined plate surface, ensuring smooth water flow and preventing the accumulation of small particles. Particles adhering to the surface of the inclined plate for a long time can reduce the water flow area or even cause blockage. To ensure the water flow area and separation efficiency, there is no need to stop the machine for cleaning, which greatly improves the separation efficiency and reduces cleaning and maintenance costs. In order to improve space utilization, in this application, multiple inclined plates 7 are arranged in a ring array in the inclined plate installation area. Preferably, they are evenly distributed in the circumferential direction, that is, set at equal angles. On the one hand, this can increase the filtration area of ​​the inclined plates 7, thereby improving the separation efficiency. On the other hand, it can make the whole body balanced, ensuring uniform force and ensuring the overall reliability and stability.

[0024] The inclined plate 7 is installed in the inclined plate installation area by an elastic element, which is a spring or rubber, or both. In this embodiment, the elastic element is a rubber spring, which includes rubber springs and composite rubber springs. The elastic element allows the inclined plate 7 to be elastically connected in the pool body 11, preventing the vibration generated from being transmitted to adjacent inclined plates 7 or the pool body 11, avoiding vibration interference or resonance, ensuring that each inclined plate 7 vibrates independently, effectively isolating the impact of vibration, ensuring the stability of the overall structure, extending the service life of the equipment, and improving operating efficiency.

[0025] The inclined plate 7 has a rectangular structure with a relatively large length, forming a strip structure. The length of the inclined plate 7 is parallel to the radius of the working chamber, which can effectively increase the number of inclined plates 7 installed per unit area, increase the filtration area and separation efficiency, and improve the overall working efficiency.

[0026] The vibratory motor 8 is installed on the top of the inclined plate 7. This facilitates the installation of the vibratory motor 8 and ensures that the vibratory motor 8 is above the water surface, preventing sewage from submerging the vibratory motor and affecting its normal operation. This facilitates installation and maintenance and ensures the overall operational stability and reliability.

[0027] In this application, each vibration motor 8 can achieve independent vibration, sequential vibration, or group vibration. Through different vibration modes, it can vibrate according to different working conditions, thereby improving cleaning efficiency and ensuring the overall separation efficiency of the thickener. Independent vibration means that each vibration motor works alone to perform precise cleaning on a specific area. Sequential vibration starts in a preset order to achieve full coverage. Group vibration divides multiple vibration motors into several groups, with each group working together to take into account both local key points and ensure overall balance, flexibly responding to diverse needs.

[0028] The vibration amplitude and frequency of the vibrating motor 8 in this application are adjustable. Different vibration amplitudes and frequencies can adapt to different application scenarios, offering high flexibility, excellent cleaning effect, and effectively ensuring separation efficiency. The vibration frequency, i.e., the number of vibrations per minute, can be adjusted according to material characteristics and the degree of blockage. Appropriate vibration frequencies can be selected based on different particle sizes to ensure efficient cleaning. The vibration frequency is adjusted by the motor's rotational speed. The vibration amplitude, i.e., the maximum displacement of the motor's vibration, can be adjusted according to the thickness of material deposits and cleaning requirements to ensure optimal vibration effect. This effectively removes deposits while avoiding excessive vibration that could damage the equipment, improving equipment durability and work efficiency. The vibration amplitude is adjusted by replacing the eccentric block of the motor, and its value depends on the mass and eccentricity of the eccentric block. This adjustable vibration amplitude means the eccentric block of the vibrating motor is replaceable.

[0029] The vibration motor 8 in this application is located at one end near or away from the central well 4, which brings the vibration motor close to the end of the inclined plate 7. Through the above arrangement, asymmetrical vibration can be generated, and lateral vibration can be easily excited, which is beneficial for the inclined plate 7 to shake off the attached particles on its surface, resulting in a good cleaning effect.

[0030] A support frame 9 is fixed within the installation area of ​​the inclined plate 7. The support frame 9 is welded from steel (channel steel or steel pipe). The inclined plate 7 is installed on the support frame 9 via elastic elements. Specifically, at least four legs of the inclined plate 7 are installed on the support frame 9 via bolts 73 and nuts 74. The elastic elements are cylindrical and are sleeved on the bolts 73, allowing the inclined plate to contact the support frame through the elastic elements, i.e., elastic contact, not rigid connection. Therefore, the vibration generated by the vibratory motor can be eliminated or reduced on the elastic elements, achieving the purpose of shock absorption and preventing the vibration force from being transmitted to the support frame 9. The support frame 9 is used to fix the central well 4 in the center of the pool and serves as the installation carrier for the inclined plate 7, facilitating the overall installation of the central well and the inclined plate, as well as the installation and adjustment of the vibratory motor.

[0031] This application utilizes the centrifugal force generated by the high-speed rotation of eccentric blocks at both ends of the vibratory motor shaft to obtain the excitation force. The vibratory motor with the excitation force drives the inclined plate to rapidly reciprocate back and forth by relying on fixed elastic elements to prevent the inclined plate from clogging and reducing the water treatment effect.

[0032] During operation, wastewater enters the central well through the feed pipe and flows steadily. It then spreads from the bottom of the central well to the surrounding area. Small particles rise with the liquid and enter from the lower part of the inclined plate layer. They flow upward through the inclined plate packing, and suspended particles settle on the bottom surface of the inclined plate. After accumulating to a certain extent, they slide down to the bottom of the tank and are scraped into the discharge pit by a scraper and discharged outside the tank. The supernatant enters the water collection tank above the inclined plate and is discharged outside the tank.

[0033] This utility model of an inclined tube thickener features independent inclined plates and independent vibration motors, allowing each inclined plate to vibrate independently. This effectively prevents small particles from adsorbing and accumulating on the inclined plate surface, ensuring smooth water flow and avoiding the reduction or even blockage caused by long-term adhesion of small particles to the inclined plate surface. This ensures the water flow area and separation efficiency, eliminating the need for machine shutdown for cleaning, significantly improving separation efficiency and reducing cleaning and maintenance costs. The vibration motors operate independently with different working modes, allowing for targeted cleaning or full coverage, resulting in good cleaning effect and high flexibility. The vibration amplitude and frequency of the vibration motors are adjustable, adapting to different material characteristics, achieving efficient cleaning and equipment protection, and improving overall operating efficiency. The optimized installation position of the vibration motors generates asymmetrical vibration and easily induces lateral vibration, facilitating the removal of adhering particles from the inclined plate surface, resulting in good cleaning effect. This utility model of an inclined tube thickener has a compact structure, self-cleaning function, and good cleaning effect, ensuring long-term stable operation of the equipment, reducing maintenance frequency, extending service life, and improving the overall efficiency of the water treatment system.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
