Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to an automatic feeding device in water purifier equipment. Background Art

[0002] The traditional water treatment process usually includes four stages: primary, secondary, tertiary treatment and post-treatment.

[0003] Among them, primary water treatment (i.e. pretreatment stage) mainly removes large particle impurities in water through physical methods, such as using sedimentation method to remove settleable solid particles.

[0004] In the process of using the sedimentation method, flocculants such as polyaluminium chloride, polyacrylamide and alum are usually added. When in use, the materials are usually mixed in the feed box and then discharged into the sedimentation tank. This method is easy to cause the materials to pile up in one place when facing a large sedimentation tank, making it difficult to effectively precipitate the entire sedimentation tank, resulting in reduced water purification efficiency. Utility Model Content

[0005] The utility model aims to provide an automatic feeding device in a water purification device which can expand material spraying and accelerate sedimentation efficiency.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an automatic feeding device in a water purification equipment includes a feeding box arranged on the wall of a sedimentation tank, an expansion frame is connected to the bottom of the feeding box, the expansion frame includes a plurality of nozzles, each of the nozzles is provided with a sliding seat, and a fixed rod is provided between the sliding seats; a screw sleeve is provided on the outer side of the nozzle located in the middle, a driving motor is provided on the expansion frame, the driving motor drives the screw sleeve to rotate, and the sliding seat is rollingly connected to the screw sleeve.

[0007] It is further configured as follows: a one-way channel is provided below the feeding box, a booster pump is provided on one side of the feeding device, a booster pipe is connected to the booster pump, and the booster pipe is connected to the bottom of the one-way channel.

[0008] It is further configured as follows: the nozzles are arranged overlappingly, and the one-way channel passes through the overlapping area of ​​the nozzles below.

[0009] It is further configured as follows: the nozzles are evenly arranged at heights on both sides, and the fixing rods are adapted to the heights of the nozzles.

[0010] It is further configured as follows: the boost pipe is provided with a one-way air valve.

[0011] It is further configured as follows: a transverse cover is provided on the sedimentation tank, and the expansion frame is provided below the transverse cover.

[0012] To sum up, the utility model has the following beneficial effects: through the automatic feeding device of the present application, the nozzle can be expanded outward, so that the material in the feeding box can be sprayed out from the end of the nozzle. When facing a larger sedimentation tank, the uniformity of the material sprayed by the feeding device on the sedimentation tank can be effectively improved, so that large particles of impurities can sink faster, thereby accelerating the water purification efficiency.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] The automatic feeding device in the water purification equipment comprises a feeding box 2 arranged on one side of the wall of a sedimentation tank 1, and an expansion frame 3 is arranged below the feeding box 2.

[0018] The expansion rack 3 has five nozzles 4, one end of the five nozzles 4 overlaps, and a one-way channel 9 is provided below the feed box 2, and the one-way channel 9 is connected to the five overlapping nozzles 4. Among them, the five nozzles 4 are evenly arranged at the heights on both sides, and the fixing rod 6 is adapted to the height of the nozzles 4, that is, as shown in the figure, the middle nozzle 4A is arranged at the reference position, the nozzles 4B and 4C are arranged at the top, and the nozzles 4D and 4E are arranged at the bottom, and the nozzle 4C is higher than the nozzle 4B, and the nozzle 4D is higher than the nozzle 4E.

[0019] The nozzles 4 are all provided with sliding seats 5, which are fixed by fixing rods 6, and the nozzles 4 are staggered in the upper and lower positions. The outer side of the nozzle 4 in the middle is sleeved with a screw sleeve 7, and the expansion frame 3 is provided with a driving motor 8, which drives the screw sleeve 7 to rotate. The sliding seat 5 in the middle is rollingly connected with the screw sleeve 7, and preferably a rolling bearing is provided in the sliding seat 5. When the driving motor 8 drives the screw to rotate, the sliding seat 5 can reciprocate along the extension direction of the nozzle 4, so that the five nozzles 4 can be freely contracted and expanded.

[0020] A booster pump 10 is provided on one side of the feeding device, a booster pipe 11 is connected to the booster pump 10, a one-way air valve 12 is provided on the booster pipe 11, and the booster pipe 11 is connected to the bottom of the one-way channel 9. After the materials in the feeding device are mixed, the materials falling into the one-way channel 9 are squeezed out from the nozzle 4 through the booster pump 10, thereby realizing the function of automatically spraying the materials.

[0021] A transverse cover 13 is provided on the sedimentation tank 1, and the expansion frame 3 is provided below the transverse cover 13. The transverse cover 13 can provide protection when the expansion frame 3 is retracted, thereby reducing the problem of impurities falling onto the nozzle 4.

[0022] Preferably, in order to ensure that the angle change of the sliding seat 5 after movement is adapted to the nozzle 4, a penetration groove can be provided in the sliding seat 5, a sleeve is rotatably provided in the penetration groove, and the sleeve rod is sleeved on the nozzle 4, thereby solving the problem that the sliding seat 5 is easily stuck on the nozzle 4 when the stroke is large. This optimized structure is suitable for the nozzle 4 with a large stroke, and can be set according to the actual width of the sedimentation tank 1.
