Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and in particular to a thickener fabric structure. Background Technology

[0002] The thickener feeding structure is a key component installed below the central feed inlet of the thickener. Its core function is to receive, distribute, and guide the incoming slurry. It is not a simple channel, but an "energy regulator" designed to dissipate and convert the kinetic energy of the high-speed, destructive slurry, ensuring that the slurry is distributed smoothly, slowly, and uniformly across the entire cross-section of the settling tank, creating crucial prerequisites for subsequent efficient gravity settling.

[0003] Currently, the most commonly used fabric structures in the industry are basic forms. Among them, the "central feed cylinder + conical reflector" structure is the most common. This structure involves adding a conical baffle at the bottom of the vertical feed cylinder, forcing the slurry flow to change direction and spread outwards after impact. In addition, double-layer sleeve structures are also sometimes used, achieving preliminary energy dissipation by causing the slurry to undergo a flow reversal between the inner and outer cylinders. These structures are essentially static and passive energy dissipation methods.

[0004] Because the existing structure relies on this simple, static mechanical obstruction and guidance, it has inherent defects. First, energy dissipation is incomplete; the outflowing slurry still generates turbulence, disrupting the settling environment and causing fine particles to fail to settle and instead become turbid with the overflow. Second, and most importantly, it is highly prone to clogging: solid particles in the slurry easily adhere and deposit in dead flow zones such as the back of the reflector and the junction of the cylinder wall, gradually hardening and eventually clogging the flow channel. This defect forces frequent equipment shutdowns for manual cleaning, which not only involves high maintenance intensity and poses safety risks but also seriously affects the continuity and stability of production. Utility Model Content

[0005] This invention provides a material feeding structure for a concentrator, which can solve the problems of easy clogging and uneven material feeding caused by the simple structure of the material feeding device in the prior art.

[0006] A condenser fabric structure, comprising: Main structure and fabric laying mechanism; The main structure includes a tank body, on which a material distribution mechanism is provided. The material distribution mechanism includes a material distribution cylinder, with a dispersion cone fixedly connected to the lower part of the material distribution cylinder. A first rotating shaft is provided inside the material distribution cylinder, and a spiral blade is fixedly connected to the first rotating shaft. A cylinder body is also provided on the tank body, with a piston plate movably connected inside the cylinder body. A guide pipe is fixedly connected to the cylinder body and is fixedly connected to the material distribution cylinder. A feed inlet is provided above the guide pipe.

[0007] Preferably, the tank body has a discharge port at the bottom and a filling port on the upper end cover.

[0008] Preferably, the fabric-laying mechanism includes a motor, which is fixedly connected to the center of the upper end cover of the tank, and the output shaft of the motor is fixedly connected to the first rotating shaft.

[0009] Preferably, a first bearing is interference-fitted to the upper end of the first rotating shaft, and the first bearing is fixedly connected to the upper end cover of the tank.

[0010] Preferably, a first gear is disposed above the first bearing, and the first gear is fixedly connected to the first rotating shaft.

[0011] Preferably, a second shaft is provided on one side of the first shaft, a second bearing is interference-connected to the second shaft, the second bearing is fixedly connected to the upper end cover of the tank, and a second gear that meshes with the first gear is fixedly connected to the upper end of the second shaft.

[0012] Preferably, a fixing pin is fixedly connected to the upper edge of the second gear, and a connecting rod is hinged to the fixing pin. The other end of the connecting rod is hinged to an ear plate fixed to the piston plate.

[0013] Preferably, the cylinder body is provided with an air inlet, and the output end of the cylinder body is fixedly connected to the feed pipe through a connecting pipe.

[0014] Preferably, the fabric cylinder and the dispersion cone are connected by a plurality of pipes arranged uniformly parallel to the outer surface of the dispersion cone.

[0015] Preferably, the upper end cover of the tank is fixedly connected to a support base, and the cylinder is fixedly connected to the support base.

[0016] Beneficial effects: By setting a spiral blade inside the feeding cylinder and a dispersing cone below it, this utility model can achieve uniform distribution during the material falling process, allowing the slurry to diffuse circumferentially along the bottom of the tank, avoiding local impact and concentrated deposition, thereby improving the settling environment of the thickener and ensuring the stability and uniformity of the feeding process.

[0017] Meanwhile, this utility model drives the connecting rod and piston plate to reciprocate through the meshing transmission of the first gear and the second gear. The air pressure pulsation effect formed by the piston plate in the cylinder periodically disturbs the material in the guide pipe and the cloth cylinder, keeping the material in a loose state and preventing particles from adhering and depositing on the cylinder wall and the surface of the spiral blade. This effectively prevents blockage and improves the self-cleaning ability of the cloth structure and the reliability of long-term operation. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a condenser fabric structure, including a main structure 100, on which a fabric feeding mechanism 200 is provided.

[0022] The main structure 100 includes a tank 101, which adopts a cylindrical conical bottom design. The middle part is a vertical cylinder, and the bottom is an inverted cone. This design facilitates the natural concentration of materials to the bottom under gravity, achieving smooth discharge and improving concentration efficiency. A discharge port 102 is provided at the bottom of the tank 101. A filling port 103 is provided on the upper end cover of the tank 101.

[0023] The material distribution mechanism 200 includes a motor 201, which is fixedly connected to the center of the upper end cover of the tank body 101. The motor 201 serves as the drive source, providing stable power output to the entire material distribution system. A first rotating shaft 202 is fixedly connected to the output shaft of the motor 201, and a spiral blade 203 is fixedly connected to the first rotating shaft 202. The spiral blade 203 pushes the material evenly downwards along the direction of the material distribution cylinder 204 during rotation, achieving dynamic distribution and avoiding local accumulation. A material distribution cylinder 204 is disposed outside the spiral blade 203, and the material distribution cylinder 204 is fixedly connected to the bottom surface of the upper end cover of the tank body 101. A dispersing cone 205 is fixedly connected to the lower end of the material distribution cylinder 204, and the dispersing cone 205 and the material distribution cylinder 204 are connected by several pipes 206. This design ensures that the material is evenly distributed and pressure-equalized through the pipes 206 before entering the dispersing cone 205, thus achieving a circular uniform distribution. The pipes 206 are evenly arranged parallel to the outer surface of the dispersing cone 205. This helps maintain a consistent velocity of the material during outflow, avoiding turbulence. A first bearing 207 is interference-fitted to the upper end of the first rotating shaft 202, and the first bearing 207 is fixedly connected to the upper end cover of the tank body 101. This ensures the rotational stability of the first rotating shaft 202 and reduces mechanical wear. A first gear 208 is disposed above the first bearing 207, and the first gear 208 is fixedly connected to the first rotating shaft 202. A second rotating shaft 209 is disposed on one side of the first rotating shaft 202. A second bearing 210 is interference-fitted to the second rotating shaft 209, and the second bearing 210 is fixedly connected to the upper end cover of the tank body 101. A second gear 211 is fixedly connected to the upper end of the second rotating shaft 209. The second gear 211 meshes with the first gear 208 for transmission. A support base 221 is also fixedly connected to the upper end cover of the tank body 101, and a cylinder 217 is fixedly connected to the support base 221. A piston plate 214 is movably connected inside the cylinder 217, and a pair of lugs 215 are fixedly connected to the piston plate 214. A pin is fixedly connected between the two lugs 215, and a connecting rod 213 is hinged to the pin. A fixing pin 212 is fixedly connected to the upper edge of the second gear 211, and the connecting rod 213 is hinged to the fixing pin 212. The second gear 211 drives the connecting rod 213 to reciprocate, which in turn drives the piston plate 214 to reciprocate, thereby realizing the conversion of mechanical energy into air pressure pulsating energy and forming an automatic anti-blocking airflow. An air inlet 216 is provided on the cylinder 217. A guide pipe 219 is fixedly connected to the upper end of the material distribution cylinder 204. The guide pipe 219 extends out of the tank 101 and is fixedly connected to an inlet 220 at its end. A connecting pipe 218 is fixedly connected to the output end of the cylinder 217, and the other end of the connecting pipe 218 is fixedly connected to the guide pipe 219. A closed airflow channel is formed, so that the air pressure change generated when the piston plate 214 moves can directly act on the inside of the feed pipe 219, thereby enhancing the anti-clogging effect.The feeding port 103 is fixedly connected to the cloth cylinder 204 and is used to add flocculants and other coagulation aids into the system.

[0024] Working principle: After the material enters the feed pipe 219 through the feed inlet 220, it flows into the inside of the distribution cylinder 204. After the motor 201 starts, it drives the first rotating shaft 202 to rotate. The spiral blades 203 on the first rotating shaft 202 push the material down along the inner wall of the distribution cylinder 204 and distribute it evenly into the tank 101 through the dispersing cone 205 at the lower end, realizing the ring-shaped material distribution.

[0025] During the driving process of motor 201, the first gear 208 on the first rotating shaft 202 and the second gear 211 on the second rotating shaft 209 mesh with each other for transmission. The fixed pin 212 on the second gear 211 drives the connecting rod 213 to swing back and forth, thereby pushing the piston plate 214 in the cylinder 217 to move up and down reciprocally. The periodic movement of the piston plate 214, through the airflow pulsation formed by the connection pipe 218 and the guide pipe 219, causes intermittent air pressure disturbance inside the cloth cylinder 204, which keeps the material in a loose state during the flow process, prevents particles from adhering and depositing between the spiral blade 203 and the cloth cylinder 204, and achieves an automatic anti-clogging effect.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
