Description

Technical Field

[0001] This invention relates to the field of concentration equipment technology, specifically to a wastewater filtration and concentration device. Background Technology

[0002] In solid-liquid separation fields such as river dredging, dewatering and drying, sludge dewatering in sewage treatment plants, and fiber pulp concentration in paper mills, the high water content of the initial slurry would significantly reduce the processing capacity of the dewatering equipment if it were directly fed into the equipment. Therefore, the initial slurry is pre-shrunk before dewatering to increase the dewatering rate.

[0003] Since its invention, the concentration device has been widely used in many fields such as chemical industry, pharmaceutical production and processing industry, mineral processing industry, and sewage treatment. In the process of industrial wastewater treatment, the filtration, concentration and purification of wastewater are particularly critical and directly affect the wastewater discharge problem.

[0004] Existing technology includes a Chinese patent with authorization announcement number CN211328379U, entitled "A Filtration and Concentration Device for Wastewater Purification." This patent discloses a filtration and concentration device for wastewater purification, comprising a first power unit, a purification tank, a first filter plate, a rotating drum, a connecting plate, a second filter plate, a second power unit, a waste treatment tank, an extrusion plate, and a collection tank. A feed funnel is located at the top of the rotating drum; a drain outlet is located at the bottom of the purification tank; the rotating drum is located inside the purification tank, and the first power unit is located at the top of the purification tank; a connecting plate and multiple openings are provided on the surface of the rotating drum, and a brush is provided on the end face of the rotating drum furthest from the drum; the second filter plate is located inside the purification tank. A drain pipe is provided on the front of the purification tank; the feed end of the waste treatment tank is located between the lower end of the extrusion plate and the upper end of the waste collection tank. This patent is a multi-functional device integrating filtration, concentration, and compression, enabling timely cleaning of the filtration device and extending its service life.

[0005] For example, Chinese patent CN220878014U, entitled "A Filtration and Concentration Device for Wastewater Purification," discloses a wastewater purification filtration and concentration device, relating to the field of wastewater purification technology. It includes a fixed tank and a wastewater discharge pipe. Three ring-shaped support frames are welded to the lower outer wall of the fixed tank, and a filtration and concentration cylinder is installed inside the fixed tank. The surface of the filtration and concentration cylinder has evenly distributed filter holes. A filter hole anti-clogging mechanism is provided inside the fixed tank, and a driving mechanism is located at the top of the fixed tank. The filter hole anti-clogging mechanism includes a crushing component, a ring-shaped brush, a reciprocating slider, a guide block, and a reciprocating lead screw. In the filter hole anti-clogging mechanism designed in this patent, during the high-speed rotation of the filtration and concentration cylinder, some larger impurities are thrown onto the spiral crushing blades and thoroughly crushed. Then, the reciprocating ring-shaped brush effectively cleans the filter holes on the surface of the filtration and concentration cylinder, resulting in a better anti-clogging effect.

[0006] Existing technologies, including the aforementioned patents, can meet the concentration requirements to a certain extent. However, when samples are subjected to centrifugal force, they tend to adhere to the inner wall of the centrifuge tube. To facilitate centrifugation, the centrifuge tube is typically designed in a conical shape, allowing the sample to move upwards along the inner wall as the tube rotates. The concentrated sample is then collected, hence the inclusion of a collection component on the inner side of the extended end. However, in practical use, fixing the collection component to the centrifuge tube with bolts makes installation and removal inconvenient; conversely, if a movable design is used, the stability of the collection component under centrifugal force cannot be guaranteed, presenting certain shortcomings.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-14 The present invention provides a technical solution: a wastewater filtration and concentration device, including a device body 1 and a centrifuge cylinder 2 rotatably connected inside the device body 1. The centrifuge cylinder 2 has multiple separation holes 21 on its periphery. A collection frame 3 is installed on the centrifuge cylinder 2. A snap-fit ​​positioning mechanism is provided between the collection frame 3 and the centrifuge cylinder 2. A power mechanism 4 is provided between the collection frame 3 and the centrifuge cylinder 2. When the power mechanism 4 drives the centrifuge cylinder 2 to rotate inside the device body 1 to perform concentration operations, the snap-fit ​​positioning mechanism fixes the collection frame 3 and the centrifuge cylinder 2.

[0024] Specifically, the wastewater filtration and concentration equipment includes a main body 1 and a centrifuge cylinder 2 rotatably connected inside the main body 1. Multiple separation holes 21 are formed on the periphery of the centrifuge cylinder 2, allowing centrifugation to occur through these holes as the cylinder rotates. More specifically, a filter membrane is installed on the inner wall of the centrifuge cylinder 2; this is a common technique in centrifugation and will not be elaborated upon here. A collection frame 3 is installed on the centrifuge cylinder 2 to collect the concentrated sample. A locking and positioning mechanism is provided between the collection frame 3 and the centrifuge cylinder 2, improving the stability of the collection frame 3 during high-speed rotation of the centrifuge cylinder 2 and enhancing its effectiveness. A power mechanism 4 is installed between the collection frame 3 and the centrifuge cylinder 2, providing power for the high-speed rotation of the centrifuge cylinder 2. When the power mechanism 4 drives the centrifuge cylinder 2 to rotate inside the main body 1 for concentration, the locking and positioning mechanism secures the collection frame 3 to the centrifuge cylinder 2. During operation, wastewater enters the centrifuge drum 2, and the power mechanism 4 drives the centrifuge drum 2 to rotate at high speed. Centrifugal force causes the liquid to be discharged through the separation hole 21, while the solids are thrown against the drum wall and move upwards. The collection frame 3 is automatically fixed to the centrifuge drum 2 during centrifugation through a snap-fit ​​positioning mechanism, thereby collecting the concentrated solid material. During the rotation of the centrifuge drum 2, the snap-fit ​​positioning mechanism secures the collection frame 3 to the centrifuge drum 2, effectively solving the problem of traditional collection components being prone to loosening or difficult to disassemble due to centrifugal force. This ensures the stability and safety of the collection components during high-speed centrifugation and facilitates quick disassembly, cleaning, or replacement of the collection frame 3 after shutdown, improving the ease of operation and maintenance efficiency of the equipment.

[0025] In the embodiments provided by this invention, a mounting platform 5 is fixedly connected to the centrifuge cylinder 2, and the snap-fit ​​positioning mechanism includes multiple snap-fit ​​parts 6 disposed between the collection frame 3 and the mounting platform 5. Specifically, the mounting platform 5 is fixed to the centrifuge cylinder 2, and the snap-fit ​​positioning mechanism consists of multiple snap-fit ​​parts 6 distributed between the collection frame 3 and the mounting platform 5. The connection and fixation between the collection frame 3 and the centrifuge cylinder 2 are achieved through the mechanical cooperation of the snap-fit ​​parts 6. The distributed connection of multiple snap-fit ​​parts 6 enhances the connection strength and uniformity between the collection frame 3 and the centrifuge cylinder 2, prevents shaking or detachment caused by uneven centrifugal force, and improves the stability and safety of equipment operation.

[0026] In the embodiments provided by this invention, the locking component 6 includes a locking block 61, on which a connecting plate 62 is fixedly connected. The mounting platform 5 has a locking groove 63 and a through groove 64, which are in communication. The mounting platform 5 has the locking groove 63 and the through groove 64. The locking block 61 is inserted into the through groove 64 via the connecting plate 62 and engages with the locking groove 63, achieving mechanical locking. When the centrifuge cylinder 2 is not rotating, the locking block 61 will naturally fall into the through groove 64, allowing for free disassembly and installation of the collection frame 3.

[0027] In the embodiments provided by this invention, the collection frame 3 is provided with a number of pressure-applying parts 7 equal to the number of snap-fit ​​parts 6. Each pressure-applying part 7 includes a connecting rod 72 fixedly connected to the connecting plate 62, and the connecting rod 72 is slidably connected to the collection frame 3. A counterweight 71 is fixedly connected to the connecting rod 72. Under the action of centrifugal force, the counterweight 71 pulls the connecting rod 72, making the snap-fit ​​part 61 more tightly snap into the snap-fit ​​groove 63. By utilizing centrifugal force to automatically enhance the tightness of the snap-fit, it can automatically lock during high-speed rotation without external operation, which not only improves the reliability of the connection but also simplifies the structural design.

[0028] In the embodiment provided by the present invention, the bottom of the collection frame 3 is provided with an installation groove 65, the connecting plate 62 is slidably connected to the installation groove 65, and a return spring 73 is also provided between the connecting plate 62 and the installation groove 65. The bottom of the collection frame 3 is provided with an installation groove 65, the connecting plate 62 slides in the installation groove 65, and the return spring 73 pushes the connecting plate 62 to reset in the non-centrifugal state, so that the locking block 61 disengages from the locking groove 63. That is, when the centrifuge cylinder 2 is not rotating, the locking block 61 will naturally fall into the through groove 64, so that the collection frame 3 can be freely disassembled and installed.

[0029] In the embodiments provided by the present invention, the collection frame 3 is provided with a feeding channel 31 and a storage space 32, and the feeding channel 31 and the storage space 32 are connected. Wastewater enters the storage space 32 through the feeding channel 31, and the solid materials are separated and stored in the storage space 32 under centrifugal action, avoiding blockage and leakage, and improving the concentration efficiency and collection capacity.

[0030] In the embodiments provided by the present invention, the centrifuge cylinder 2 is conical in shape and is connected to the feed channel 31 and the feed channel 31 of the collection frame 3. When rotating, the solid moves upward along the conical surface and enters the collection frame 3. At the same time, the conical structure uses centrifugal force to naturally guide the solid material to move upward, which improves the separation efficiency and collection effect, while reducing material residue and cleaning difficulty.

[0031] In the embodiments provided by this invention, the power mechanism 4 includes a servo motor 41 installed inside the equipment body 1, and the centrifuge cylinder 2 is rotatably connected to the equipment body 1 via a rotating rod 42. The drive shaft of the servo motor 41 and the rotating rod 42 are connected by a synchronous component 43. The synchronous component 43 includes a first synchronous pulley mounted on the rotating rod 42 and a second synchronous pulley mounted on the drive shaft of the servo motor 41. The first and second synchronous pulleys are connected by a synchronous belt drive. Using the servo motor 41 and synchronous transmission ensures smooth power transmission, precise control, and adaptability to different speed requirements, improving the adaptability and energy efficiency of the equipment. Furthermore, the synchronous belt drive has a simple structure, low noise, convenient maintenance, high transmission efficiency, and good buffering and overload protection capabilities.

[0032] In the embodiments provided by the present invention, the device body 1 is provided with a liquid outlet channel 8, and a valve is installed on the liquid outlet channel 8. The concentrated liquid is discharged through the liquid outlet channel 8, and the valve controls the discharge process.

[0033] It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source, and this application is equipped with a control system for controlling the operation of the entire equipment.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
