Description

Technical Field

[0001] This utility model relates to the field of flocculant technology, specifically to an online fully automatic liquid mixing and feeding device for powdered flocculants. Background Technology

[0002] The online fully automatic liquid preparation, mixing and feeding device for powdered flocculants is a device used to automatically prepare, mix and feed powdered flocculants with water.

[0003] 1. Currently, the liquid mixing and feeding device directly and centrally adds powdered flocculants during operation. Adding a large amount of powdered flocculants at once makes it difficult to fully mix with water or the liquid to be treated in a short time. This can lead to excessively high flocculant concentrations in some areas and low concentrations in other areas. Furthermore, when a large amount of powdered flocculants is added at once, they tend to agglomerate and form clumps, resulting in poor working quality of the liquid mixing and feeding device.

[0004] 2. Powdered flocculants are hygroscopic and easily absorb moisture from the air. After absorbing moisture, the surface of the particles dissolves and re-agglomerates, resulting in clumping. They also adhere to the inner wall of the feed shell, which not only affects the feeding efficiency but also causes material waste, resulting in poor performance of the liquid mixing and feeding device. Utility Model Content

[0005] To address the above problems, this utility model provides an online fully automatic liquid preparation, mixing and feeding device for powdered flocculants, which solves the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online fully automatic liquid mixing and feeding device for powdered flocculants, comprising a mixing device housing, a feeding shell connected to the top of the mixing device housing, a feeding plate connected to the top of the mixing device housing, an adjusting plate provided on the top of the feeding plate, and a discharge plate provided on the top of the adjusting plate;

[0007] The top of the mixing device housing is provided with an adjustment groove, and an adjustment block is connected to one side of the adjustment plate. The adjustment block is located inside the adjustment groove, and an adjustment handle is connected to the top of the adjustment block.

[0008] The feeding plate and the adjusting plate are internally fitted with a rotating shaft. The top of the rotating shaft is connected to the bottom of the discharge plate. The top of the discharge plate is connected to a connecting rod. Several crushing rollers are fixedly connected to the outside of the connecting rod. The top of the discharge plate is connected to two scrapers. Several breaking rods are connected to one side of the scrapers.

[0009] Preferably, a driven sprocket is externally connected to the rotating shaft.

[0010] Preferably, a rotating rod is rotatably connected inside the housing of the mixing device, and a driving sprocket is connected outside the rotating rod. The driving sprocket and the driven sprocket are connected by a chain drive.

[0011] Preferably, the rotating rod is externally connected to several fixed rods, one end of each fixed rod is connected to an outer helical blade, and the other end of each fixed rod is connected to an inner helical blade.

[0012] Preferably, a motor is connected to the top of the mixing device housing, and the output end of the motor is connected to the top of the rotating rod in a transmission connection.

[0013] Preferably, a protective shell is connected to the inner top surface of the mixing device housing, the outside of the rotating rod is rotatably connected to the protective shell, and both the driving sprocket and the driven sprocket are located inside the protective shell.

[0014] Preferably, a water injection pipe is connected to the top of the mixing device housing, and a discharge pipe is connected to one side of the mixing device housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This application allows for multiple additions of powdered flocculant by rotating the discharge plate in conjunction with the adjusting plate and the feeding plate. This avoids the problem of adding a large amount of powdered flocculant at once, which makes it difficult to mix it fully with water in a short time. It solves the problem that when a large amount of powdered flocculant is added at once, it is easy for them to agglomerate and form clumps, which affects the mixing effect of the solution. This is beneficial to improving the working quality of the solution mixing and feeding device.

[0017] 2. This application uses a discharge plate to drive the scraper, breaking rod, and crushing roller to rotate, which can crush the powder flocculant inside the feed shell and prevent it from agglomerating. The rotation of the scraper can also scrape the inner wall of the feed shell to prevent the powder flocculant from adhering to the inside of the feed shell. This solves the problem that the powder flocculant will affect the feeding efficiency due to agglomeration and the material waste caused by its adhesion to the inner wall of the feed shell. It is beneficial to improve the practical performance of the liquid mixing and feeding device.

[0018] 3. This application does not require an additional motor; it only needs to be driven by the motor of the mixing mechanism. The feeding of powder flocculant can be controlled by rotating the adjusting plate through the adjusting handle. During normal operation, the adjusting plate is opened to allow the material to be fed normally. When the powder flocculant has been added and mixing and stirring need to continue, the adjusting plate is closed to allow the liquid mixing to proceed normally. No additional motor is needed to control the rotation of the discharge plate and the adjusting plate, which helps to reduce the operating cost of the liquid mixing and feeding device.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Please see Figures 1 to 6 An online fully automatic liquid mixing and feeding device for powder flocculants includes a mixing device housing 1, with a feed shell 4 connected to the top of the mixing device housing 1. When using the liquid mixing and feeding device, the powder flocculant is transported to the feed shell 4 by a screw conveyor, and the powder flocculant is fed into the interior of the mixing device housing 1 through the feed shell 4 for mixing. A feeding plate 5 is connected to the top of the mixing device housing 1, an adjusting plate 6 is provided on the top of the feeding plate 5, and a discharge plate 7 is provided on the top of the adjusting plate 6.

[0028] An adjustment groove is provided on the top of the mixing device housing 1. An adjustment block 8 is connected to one side of the adjustment plate 6. The adjustment block 8 slides inside the adjustment groove during adjustment. The adjustment block 8 is located inside the adjustment groove. An adjustment handle 9 is connected to the top of the adjustment block 8. When the liquid mixing and feeding device is used normally, the adjustment plate 6 is opened. At this time, the feeding space of the adjustment plate 6 is aligned with the feeding space on the feeding plate 5. Therefore, when the rotating rod 17 drives the outer spiral blade 19 and the inner spiral blade 20 to mix the liquid material, it will also drive the rotating shaft 10 and the discharge plate 7 to rotate simultaneously to feed the powder flocculant multiple times to prevent one-time concentrated feeding.

[0029] Therefore, only one motor is needed to achieve mixing and multiple feedings of powder flocculant. However, during operation, too much powder flocculant should not be added. To prevent the need to continue mixing the liquid material after the appropriate amount of powder flocculant has been added, the feeding of powder flocculant is affected by the rotating rod 17. Therefore, the operator can hold the adjusting handle 9 to rotate the adjusting block 8 and the adjusting plate 6, so that the feeding space on the adjusting plate 6 is misaligned with the feeding space on the feeding plate 5. At this time, no matter how the discharge plate 7 rotates, it will not feed powder flocculant. Therefore, the rotating rod 17 can still rotate to mix the liquid material.

[0030] This eliminates the need for an additional motor; the feeding mechanism can be driven solely by the motor of the mixing mechanism. No additional motor is required to control the rotation of the discharge plate and the adjusting plate, which reduces the operating cost of the liquid mixing and feeding device.

[0031] A rotating shaft 10 is sleeved inside the feeding plate 5 and the adjusting plate 6. The top of the rotating shaft 10 is connected to the bottom of the discharge plate 7. A connecting rod 11 is connected to the top of the discharge plate 7. Several crushing rollers 12 are fixedly connected to the outside of the connecting rod 11. Two scrapers 13 are connected to the top of the discharge plate 7. Several breaking rods 14 are connected to one side of the scrapers 13. The rotating shaft 10 drives the discharge plate 7 to rotate, thereby controlling the feeding of powder flocculant. It should be further noted that a fan-shaped feeding space is opened on one side of the feeding plate 5, the adjusting plate 6, and the discharge plate 7. Therefore, the powder flocculant is fed in when the feeding space on the discharge plate 7 corresponds to the feeding space on the feeding plate 5 and the adjusting plate 6 by rotating the discharge plate 7. When the feeding space on the discharge plate 7 is misaligned with the feeding space on the feeding plate 5 and the adjusting plate 6, the powder flocculant cannot be fed into the interior of the mixing device housing 1.

[0032] It should be noted that the feeding plate 5 remains stationary throughout the entire process;

[0033] This allows for multiple additions of powdered flocculant, avoiding the problem of insufficient mixing with water in a short time when a large amount of powdered flocculant is added at once. It also solves the problem that when a large amount of powdered flocculant is added at once, it tends to agglomerate and form clumps, affecting the mixing effect of the solution.

[0034] When the discharge plate 7 rotates, it will drive the scraper 13 to rotate as well. One side of the scraper 13 will scrape the inside of the feed shell 4, and the scraper 13 will also drive the breaking rod 14 to rotate to initially break up the clumps in the powder flocculant. The discharge plate 7 will also drive the connecting rod 11 and the crushing roller 12 to rotate to further break up the clumps in the powder flocculant. This solves the problem that the powder flocculant will affect the feeding efficiency due to the presence of clumps during feeding and cause material waste due to its adhesion to the inner wall of the feed shell.

[0035] The external connection of the rotating shaft 10 is a driven sprocket 15.

[0036] A rotating rod 17 is rotatably connected inside the housing 1 of the mixing device, and a drive sprocket 16 is connected to the outside of the rotating rod 17. The drive sprocket 16 and the driven sprocket 15 are connected by a chain drive. When the rotating rod 17 rotates, it will drive the drive sprocket 16 to rotate, so that the drive sprocket 16 will drive the driven sprocket 15 to rotate synchronously through the chain, thereby causing the driven sprocket 15 to drive the rotating shaft 10 to rotate.

[0037] It is important to note that when the rotating shaft 10 rotates, it will rotate inside the feeding plate 5 and the adjusting plate 6, and the rotating shaft 10 will drive the discharge plate 7 to rotate.

[0038] The rotating rod 17 is externally connected to several fixed rods 18. One end of the fixed rod 18 is connected to an outer spiral blade 19, and the other end of the fixed rod 18 is connected to an inner spiral blade 20. The rotating rod 17 is driven to rotate by the output end of the motor 21, so that the rotating rod 17 drives the outer spiral blade 19 and the inner spiral blade 20 to rotate through the fixed rods 18. At this time, the liquid material will be mixed inside the mixing device housing 1, and through the cooperation of the outer spiral blade 19 and the inner spiral blade 20, the liquid material can also be mixed in the up and down direction.

[0039] A motor 21 is connected to the top of the mixing device housing 1, and the output end of the motor 21 is connected to the top of the rotating rod 17 for transmission.

[0040] A protective shell 22 is connected to the inner top surface of the mixing device housing 1. The outside of the rotating rod 17 is rotatably connected to the protective shell 22. The driving sprocket 16 and the driven sprocket 15 are both located inside the protective shell 22. It should be noted that although the liquid material does not come into contact with the inner top surface of the mixing device housing 1 when the liquid mixing and feeding device is working, the protective shell 22 is specially provided to prevent the liquid material from splashing onto the driving sprocket 16 and the driven sprocket 15 during mixing, thus affecting their service life.

[0041] A water injection pipe 2 is connected to the top of the mixing device housing 1, and a discharge pipe 3 is connected to one side of the mixing device housing 1. The water injection pipe 2 and the discharge pipe 3 are respectively connected to external equipment. The powder flocculant is added into the mixing device housing 1 through the water injection pipe 2, while the discharge pipe 3 discharges the material after the liquid mixing is completed. Both the water injection pipe 2 and the discharge pipe 3 are equipped with water pumps to transport water and materials.

[0042] When using this utility model:

[0043] First, the water injection pipe 2 and the discharge pipe 3 are connected to external equipment respectively. The water injection pipe 2 is used to add the powder flocculant into the mixing device housing 1 for mixing, while the discharge pipe 3 is used to discharge the material after the liquid mixing is completed. Both the water injection pipe 2 and the discharge pipe 3 are equipped with water pumps to transport water and materials. When using the liquid mixing and discharge device, the powder flocculant is transported to the feed shell 4 through the screw conveyor, and the powder flocculant is put into the mixing device housing 1 through the feed shell 4 for mixing.

[0044] Secondly, the output end of the motor 21 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the outer spiral blade 19 and the inner spiral blade 20 to rotate through the fixed rod 18. At this time, the liquid material will be mixed inside the mixing device housing 1, and through the cooperation of the outer spiral blade 19 and the inner spiral blade 20, the liquid material can also be mixed in the up and down direction. When the rotating rod 17 rotates, it will drive the drive sprocket 16 to rotate, so that the drive sprocket 16 will drive the driven sprocket 15 to rotate synchronously through the chain, and then the driven sprocket 15 will drive the rotating shaft 10 to rotate.

[0045] Then, the rotating shaft 10 drives the discharge plate 7 to rotate, thereby controlling the feeding of powder flocculant. It should be further noted that the discharge plate 5, the adjusting plate 6, and one side of the discharge plate 7 are all provided with fan-shaped discharge spaces. Therefore, when the discharge space on the discharge plate 7 is aligned with the discharge spaces on the discharge plate 5 and the adjusting plate 6 by rotating the discharge plate 7, the powder flocculant can be fed into the mixture device housing 1. When the discharge space on the discharge plate 7 is misaligned with the discharge spaces on the discharge plate 5 and the adjusting plate 6, the powder flocculant cannot be fed into the mixture device housing 1.

[0046] Finally, when the discharge plate 7 rotates, it will drive the scraper 13 to rotate. One side of the scraper 13 will scrape the inside of the feed shell 4, and the scraper 13 will also drive the breaking rod 14 to rotate to initially break up the clumps in the powder flocculant. The discharge plate 7 will also drive the connecting rod 11 and the crushing roller 12 to rotate to further break up the clumps in the powder flocculant.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
