Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, specifically, it relates to a flocculant feeder. Background Technology

[0002] In the deep processing of glass, a large amount of clean water is needed for processes such as edging, chamfering, drilling, and cleaning. This water must be recycled and reused, requiring the continuous addition of flocculants to purify the water. Maintaining a stable concentration of flocculants in the wastewater is crucial for ensuring water quality stability; therefore, it is essential to control the stable feeding of flocculants.

[0003] The current operating method involves filling a container with flocculant and water, manually adding the flocculant, and then using a water pump to inject the flocculant-water mixture into a WP tank containing wastewater for purification. Because the flocculant-water mixture container is closed, stirring is impossible. This manual addition method results in insufficient mixing of the flocculant and water, leading to uneven flocculant concentration within the container. Consequently, the concentration of the mixture supplied to the WP tank varies, affecting the stability of the purified water quality. Furthermore, manual addition requires multiple operations by three shifts per day, resulting in a high workload and wasted human resources. The operation also requires working at heights exceeding 5 meters, posing certain safety hazards.

[0004] For example, utility model patent CN 204841041U, published on December 9, 2015, discloses a multi-level feeding device for thickener flocculant. It includes a thickener feed well, a slurry feed pipe, a degassing tank, and a flocculant feed pipe. The slurry feed pipe extends into the degassing tank of the thickener, and the slurry enters the thickener feed well after passing through the degassing tank. The flocculant feed pipe extends directly into the interior of the thickener feed well. The end of the flocculant feed pipe is sealed, and 1-8 rows of distribution holes 5 are evenly distributed on the flocculant feed pipe, with a hole diameter of 0.5-1 mm. The flocculant feeding pressure ranges from 0.2-1 MPa. However, this multi-level feeding device for thickener flocculant cannot completely solve the aforementioned technical problems.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0018] like Figure 1As shown, the flocculant feeder includes a hopper mounting frame 1, which includes a hopper 11. A screw feeder 12 is located at the bottom of the hopper 11, and a stirring mechanism is also installed inside the hopper 11. A geared motor 2 is located above the hopper 11, connected to a conveyor shaft 21. The bottom end of the conveyor shaft 21 is connected to the screw feeder 12. The geared motor 2 provides power to the screw feeder 12. The screw feeder 12 has an external stainless steel seamless pipe and an internal spiral plate. Its upper end has a male waist hole structure that can connect with the female waist hole 32 of the stirring rod 3. When the screw feeder 12 is installed on the conveyor shaft 21, there should be no axial movement. The operation of the screw feeder 12 can quantitatively and uniformly deliver flocculant to the flocculant-water mixing container, solving the problem that the flocculant-water mixing solution container cannot be stirred. This replaces the manual multi-shift feeding method and ensures the stability of the flocculant feeding process.

[0019] like Figure 2 As shown, the stirring mechanism includes a stirring rod 3, which is horizontally positioned. The stirring rod 3 includes a bushing 31 connected to the conveying shaft 21. The stirring rod 3 is located above the top of the screw feeder 12. The output shaft of the geared motor 2 is perpendicular to the horizontal plane. The reduction ratio of the geared motor 2 is set according to the daily purified water capacity. The output shaft of the geared motor 2 is connected to the conveying shaft 21 via a coupling 22. The outer diameter of the upper end of the conveying shaft 21 is larger than the outer diameter of the lower bearing seat, serving as the support point for the lower bearing to withstand radial forces. Multiple keyways 211 are milled on the conveying shaft 21. Both the stirring rod 3 and the screw feeder 12 are connected to the conveying shaft 21 via keys, thereby enabling synchronous rotation of the stirring rod 3 and the screw feeder 12. The rotating stirring rod 3 agitates the flocculant at the inlet of the screw feeder 12, breaking up some of the clumps and preventing blockage, thus ensuring the stability of the flocculant feeding process. The upper end of the bushing 31 has a keyway for keyed transmission of the conveyor shaft 21. The lower end of the through hole in the bushing 31 is designed as a waist hole 32, which mates with the male waist hole at the upper end of the screw feeder 12 to form a male-female waist hole connection, making it difficult for the screw feeder 12 to move axially and ensuring the stability of its operation. The screw feeder 12 is connected to the lower end of the conveyor shaft 21 by a key, and its lower end is locked with bolts and a locking washer. The screw feeder 12, through the rotation of the conveyor shaft 21, delivers the flocculant quantitatively and periodically into the flocculant-water mixture container.

[0020] like Figure 3As shown, a protective sleeve 24 is provided on the outside of the conveying shaft 21. The output shaft of the geared motor 2 is connected to the conveying shaft 21 by a coupling 22. The geared motor 2 is connected to a connecting plate 41. A fixed seat 23 is connected to the bottom of the connecting plate 41. The coupling 22 is located inside the fixed seat 23. A bearing 231 is provided inside the fixed seat 23. A step 212 is provided at the top of the conveying shaft 21 to radially position the bearing 231. The conveying shaft 21 and the bearing 231 are rotatably connected. Flanges 241 are provided at both the top and bottom of the protective sleeve 24. The flange 241 at the top of the protective sleeve 24 is connected to the bottom of the fixed seat 23 by bolts. A support sleeve assembly 5 is connected to the flange 241 at the bottom of the protective sleeve 24. The protective sleeve 24 is composed of two connecting flanges 241 and welded stainless steel seamless steel pipes. The upper flange 241 is bolted to the lower end face of the fixed seat 23, and the lower flange 241 is bolted to the support seat cover plate 53 of the support sleeve assembly 5. The protective sleeve 24 prevents flocculant from entering the stirring rod 3 and the support sleeve assembly 5, avoiding corrosion and wear on both. The upper end of the conveying shaft 21 is connected to the output shaft of the geared motor 2 via a coupling 22 and a key. The upper flange of the fixed seat 23 is bolted to the connecting plate 41. The fixed seat 23 houses the bearing of the conveying shaft 21. The fixed seat 23 and the support sleeve assembly 5 provide radial force restraint to the top and bottom ends of the conveying shaft 21, ensuring the concentricity of the upper bearing position of the conveying shaft 21 and the support sleeve assembly 5.

[0021] like Figure 4 and Figure 5As shown, the support sleeve assembly 5 includes a support sleeve 51, a support base 52, a support base cover plate 53, a support plate 54, and a stainless steel round bar 55. The support sleeve 51 is located inside the support base 52, and the conveyor shaft passes through the support sleeve 51. The support sleeve 51 is made of nylon. The support base cover plate 53 is located on top of the support sleeve 51 and the support base 52. The support base cover plate 53 is connected to the support base 52 by bolts. The support plate 54 is connected to the inner wall of the hopper 11 by bolts. The stainless steel round bar 55 connects the support plate 54 and the support base 52. The support plate 54 and the stainless steel round bar 55 are both arranged at equal intervals along the circumference. The support sleeve assembly 5 consists of a support sleeve 51, a support base 52, a support base cover plate 53, a support plate 54, and a stainless steel round bar 55. During installation, the support sleeve 51 is installed inside the support base 52, and the support base cover plate 53 is installed on top of the support sleeve 51 and the support base 52. The support base cover plate 53 is bolted to the support base 52. The installed support sleeve 51, support base 52, and support base cover plate 53 are then fitted into the conveyor shaft 21. The support plate 54 is bolted to the hopper, and the support plate 54 and the support base 52 are connected by the stainless steel round bar 55. When welding the stainless steel round bar 55 to connect the support plate 54 and the support base 52, it is necessary to ensure that the bearing position at the upper end of the conveyor shaft is concentric with the support sleeve assembly 5. In the above structure, the support sleeve 51 is rotatably connected to the conveyor shaft 21, and the support plate 54 is installed on the lower inner wall of the 10 hopper 11 and fixed with bolts. Multiple support plates 54 ensure that the support sleeve 51 and the conveyor shaft 21 are coaxially arranged, and ensure the concentricity of the upper bearing position of the conveyor shaft 21 and the support sleeve assembly 5, thereby ensuring the stable operation of the conveyor shaft 21, the stirring rod 3, and the screw feeder 12. The top of the support sleeve 51 extends from the support base 52 and the support base cover plate 53, and the extended end has a tapered structure, which is adapted to the tapered connecting sleeve at the bottom of the protective sleeve 24, facilitating the bolt connection between the lower flange 241 of the protective sleeve 24 and the support base cover plate 53.

[0022] like Figure 1 As shown, a fixed bracket 4 is provided on one side of the silo fixing frame 1, and the geared motor 2 is located at the top of the fixed bracket 4. The geared motor 2 is higher than the top of the silo 11, and the conveying shaft 21 is vertically arranged. The output shaft of the geared motor 2, the fixed seat 23, the protective sleeve 24, and the support sleeve 51 are connected in sequence from top to bottom. The power transmission direction of the geared motor 2 is vertical from top to bottom, which helps to reduce the overall structural volume and does not affect the flocculant addition operation.

[0023] like Figure 2As shown, a feeder sleeve 13 is connected to the bottom of the hopper 11, and the bottom of the feeder sleeve 13 is lower than the screw feeder 12. The design of the feeder sleeve 13 being lower than the screw feeder 12 helps to avoid splashing when the flocculant is swirled out. The upper flange of the feeder sleeve 13 is bolted to the lower flange of the hopper 11. There is a certain gap between the feeder sleeve 13 and the screw feeder 12. When the screw feeder 12 rotates, it will swirl out the flocculant in the hopper 11 through centrifugal force and gravity, so as to achieve uniform feeding of flocculant and help to ensure the stability of flocculant concentration.

[0024] like Figure 1 As shown, the bottom of the silo 11 is conical. The upper part of the silo 11 is cylindrical, which increases the feeding space and can meet the feeding requirements of three shifts a day. The lower part of the silo 11 is conical, and the feeding is smooth. The bottom flange of the silo 11 is bolted to the flange on the feeder sleeve 13. The conical shape of the silo 11 makes it easier for the flocculant to form a flow tendency towards the center when moving in the silo, which helps to reduce the retention of flocculant on the inner wall of the silo 11.

[0025] like Figure 1 As shown, the fixed bracket 4 is constructed by welding square tubes. The main body of the fixed bracket 4 is constructed by welding multiple square tubes, and it is also equipped with triangular supports to ensure the strength of the fixed bracket 4. The fixed bracket 4 ensures that the conveying shaft 21 connected to the geared motor 2 is perpendicular to the horizontal plane, and ensures that the spiral plate of the screw feeder 12 will not rub against the feeder sleeve 13 when the conveying shaft 21 is running. The geared motor 2 is fixed to the fixed bracket 4 by three connecting plates 41 to ensure its stable and reliable operation. When assembling the fixed bracket 4, the crossbeam of the fixed bracket 4 is welded to the two side plates of the geared motor 2, and the lower part of the fixed bracket 4 is welded to two of the connecting beams of the three legs of the hopper fixed frame 1. Two triangular supports are added between the crossbeam and the column of the fixed bracket 4 to connect the two columns laterally to ensure the strength of the fixed bracket 4. The fixed bracket 4 ensures that the conveying shaft 21 is perpendicular to the horizontal plane, and that there is no friction noise between the screw feeder 12 and the feeder sleeve 13 when the conveying shaft 21 is running. The hopper fixing frame 1 consists of legs, a transverse connecting beam, a ring beam, and a support base: the support base is fixed on the ring beam and welded to the hopper; the legs are welded to the transverse connecting beam, and the transverse connecting beam is welded to the two side plates of the geared motor 2.

[0026] When using the flocculant feeder, the space of the silo 11 is used to add the amount of flocculant needed for three shifts of the day at once. The upper and lower limits of the liquid level are monitored by the level gauge in the flocculant and water mixing container. The opening and closing of the water supply pipeline and the reduction motor 2 are controlled. When the level gauge reaches the upper limit, the flocculant feeder starts to add an appropriate amount of flocculant. When the level gauge reaches the lower limit, water is automatically added to ensure that the flocculant is fed evenly and its concentration is kept stable within a reasonable range. This ensures that the container can continuously supply the WP tank containing sewage with the mixed solution of flocculant and water, achieving self-circulation and effectively reducing the workload of the three shifts of personnel.

[0027] This flocculant feeder replaces the existing manual multi-shift feeding method, reducing the number of high-altitude operations, eliminating safety hazards, reducing the workload of personnel, and avoiding the waste of human resources. The use of the screw feeder 12 ensures that the flocculant can be supplied evenly. The stirring rod 3 is also set to prevent material blockage, ensuring the stability of the flocculant feeding process, ensuring the stability and uniformity of the flocculant concentration, and ensuring the stability of water purification quality.

[0028] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
