Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, specifically to a polyferric sulfate storage silo. Background Technology

[0002] Polyferric sulfate is a high-performance inorganic polymeric coagulant. It is a pale yellow amorphous powder that is highly soluble in water and hygroscopic. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, municipal sewage, and sludge dewatering. Storage silos are frequently used to store polyferric sulfate during its production and processing.

[0003] Utility model patent CN221564282U discloses a gypsum powder storage silo. The silo includes a storage structure and a cleaning structure. The storage structure includes a silo body, an inlet pipe, an outlet pipe, and an anti-clogging component. The inlet pipe and outlet pipe are connected to the silo body. The anti-clogging component is located inside the outlet pipe. The cleaning structure includes a fixing frame, a cleaning component, support legs, a collection box, a filter screen, a water pump, a water outlet pipe, and a water outlet component. The fixing frame is connected to the collection box. The cleaning component is located on one side of the fixing frame. The two ends of the support legs are connected to the silo body and the collection box, respectively. The filter screen is located inside the collection box. The water pump is installed on one side of the support legs and is connected to the collection box. The water outlet pipe is connected to the water pump, and the water outlet component is connected to the water outlet pipe. The anti-clogging component helps prevent blockages during material discharge. The cleaning component facilitates cleaning of the hopper surface. The water outlet component allows for easy spraying of water onto the hopper surface, improving the cleaning effect. The cleaned water flows into the collection tank and is filtered through a filter. By turning on the water pump, the water is re-entered into the water outlet component through the water outlet pipe, facilitating the reuse of water resources.

[0004] Although the gypsum powder storage silo facilitates the cleaning of the equipment surface, the device still has the following problems in actual use: the device discharges material through the discharge pipe, but the powdery material will generate a lot of dust due to the impact when discharged. The dust not only pollutes the environment, but also harms the health of the workers. In view of this, we propose a polyferric sulfate storage silo. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a polyferric sulfate storage silo, in which the dust generated during discharge is confined inside the container by a sealed cover, preventing the polyferric sulfate dust from spreading into the air and causing environmental pollution, thus protecting the health of workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polyferric sulfate storage silo includes a hollow silo body, inside which multiple stirring shafts are rotatably mounted. Multiple stirring blades are coaxially keyed to the stirring shafts. The top of the stirring shafts passes through the top of the silo body, and a transmission assembly is installed between the tops of two adjacent stirring shafts. A first motor for driving the stirring shafts to rotate is installed above the silo body. A discharge pipe is provided at the bottom of the silo body.

[0008] Below the discharge pipe is a discharge section, which includes a base plate. Two symmetrical side plates are fixed to the top of the base plate, and threaded rods are threaded onto the side plates. Clamping blocks are rotatably mounted at the two opposite ends of the two threaded rods. A liftable sealing cover is installed above the two clamping blocks, with a sealing gasket fixed to the top of the bottom opening of the sealing cover. A telescopic pipe connected to the discharge pipe is installed on the top of the sealing cover. Two connecting sleeves are fixed to the outer wall of the sealing cover, with connecting grooves at the connecting sleeves. Support plates are installed on both sides of the sealing cover, with connecting blocks fixed to one end of each support plate. The connecting blocks are inserted into the corresponding connecting grooves. Connecting bolts are threaded onto the outer wall of the connecting sleeves, with the ends of the connecting bolts passing through the connecting blocks. A lead screw is threaded onto the right support plate opposite to the connecting block, and a second motor for driving the lead screw is installed above the lead screw. A guide rod is slidably mounted on the left support plate opposite to the connecting block.

[0009] In addition, the polyferric sulfate storage silo proposed in the application may also have the following additional technical features:

[0010] Specifically, each of the four corners of the chamber is fixed with a support leg, and a crossbeam is fixed between two support legs; the top of the lead screw is rotatably connected to the crossbeam through a bearing, and the top of the guide rod is fixedly connected to the crossbeam through bolts.

[0011] Specifically, the top of the chamber is fixedly connected to a U-shaped bracket by bolts, and the top of the stirring shaft is rotatably connected to the bracket by a bearing.

[0012] Specifically, a feeding port is fixed on the right side of the top of the silo body, and a plug is threaded onto the feeding port.

[0013] Specifically, each of the two opposite ends of the two threaded rods is equipped with a handwheel, and the handwheel is coaxially keyed to the threaded rod.

[0014] Specifically, a valve, which is a ball valve, is installed at the discharge pipe.

[0015] Specifically, the telescopic tube is elastic and is a corrugated tube.

[0016] Specifically, the two opposing end faces of the two clamping blocks are both arc-shaped, and the clamping blocks are made of stainless steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The design of the silo and discharge section serves two purposes: First, the silo facilitates the storage of polyferric sulfate, while the multiple stirring shafts ensure proper agitation of the stored polyferric sulfate, preventing clumping. Second, during discharge, the container is clamped and secured between two clamping blocks, allowing the sealing cap to descend and cover the top opening of the container. The sealing gasket ensures a tight seal between the cap and the container, confining the dust generated during discharge within the container and preventing the polyferric sulfate dust from spreading into the air and polluting the environment. This also protects the health of the workers. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment provides a technical solution:

[0029] Please see Figures 1-4 As shown, a polyferric sulfate storage silo includes a hollow silo body 1. Multiple stirring shafts 12 are rotatably mounted inside the silo body 1. Multiple stirring blades 13 are coaxially keyed to the stirring shafts 12. The top ends of the stirring shafts 12 pass through the top of the silo body 1. A transmission assembly is installed between the top ends of two adjacent stirring shafts 12. A first motor 16 for driving the stirring shafts 12 is installed above the silo body 1. A discharge pipe 18 is provided at the bottom of the silo body 1. A discharge section 2 is provided below the discharge pipe 18. The discharge section 2 includes a bottom plate. Two symmetrical side plates 28 are fixed to the top of the bottom plate. Threaded rods 29 are threadedly connected to the side plates 28. Clamping blocks 291 are rotatably mounted at the two opposite ends of the two threaded rods 29. A liftable sealing cover 20 is installed above the space between the two clamping blocks 291 to seal the area. A sealing gasket 200 is fixed at the top of the bottom opening of the cover 20; a telescopic pipe 21 connected to the discharge pipe 18 is installed at the top of the sealing cover 20; two connecting sleeves 22 are fixed on the outer wall of the sealing cover 20, and connecting grooves 220 are opened at the connecting sleeves 22; support plates 24 are installed on both the left and right sides of the sealing cover 20, and a connecting block 25 is fixed at one end of the support plate 24. The connecting block 25 is inserted into the corresponding connecting groove 220. A connecting bolt 23 is threaded on the outer wall of the connecting sleeve 22, and the end of the connecting bolt 23 passes through the connecting block 25; a lead screw 27 is threaded on the right end of the support plate 24 away from the connecting block 25, and a second motor 3 for driving the lead screw 27 to rotate is installed above the lead screw 27; a guide rod 26 is slidably installed on the left end of the support plate 24 away from the connecting block 25.

[0030] In this embodiment, each of the four corners of the hopper 1 is fixed with a support leg 17, and a crossbeam 170 is fixed between two support legs 17. The top end of the lead screw 27 is rotatably connected to the crossbeam 170 via a bearing, and the top end of the guide rod 26 is fixedly connected to the crossbeam 170 via bolts. The support legs 17 provide stable support for the hopper 1, ensuring the stability of the entire structure. At the same time, the crossbeam 170 provides stable support for the lead screw 27 and the guide rod 26.

[0031] In this embodiment, a U-shaped fixing frame 11 is bolted to the top of the chamber 1, and the top end of the stirring shaft 12 is rotatably connected to the fixing frame 11 via a bearing. The fixing frame 11 provides a stable support point for the stirring shaft 12.

[0032] In this embodiment, a filling port 10 is fixed on the top right side of the silo body 1, and a plug is threaded onto the filling port 10. The filling port 10 facilitates the operator in adding polyferric sulfate, while the threaded plug ensures the material is sealed during storage, effectively preventing dust and moisture.

[0033] In this embodiment, handwheels 290 are installed at both opposite ends of the two threaded rods 29, and the handwheels 290 are coaxially keyed to the threaded rods 29. The handwheels 290 facilitate the rotation of the threaded rods 29, improving the ease of operation.

[0034] In this embodiment, a valve 19 is installed at the discharge pipe 18. The valve 19 is a ball valve. The ball valve has the advantages of simple structure, good sealing performance, and convenient operation, which ensures the stability and reliability of the discharge process.

[0035] In this embodiment, the telescopic tube 21 is telescopic and is a corrugated tube. The telescopic tube 21 is telescopic, thereby meeting the need for raising and lowering the sealing cover 20.

[0036] In this embodiment, the two opposing end faces of the two clamping blocks 291 are both arc-shaped, and the clamping blocks 291 are made of stainless steel. The arc-shaped design improves the stability and reliability of the clamping blocks 291 in holding the container; while the stainless steel material has the advantages of corrosion resistance, wear resistance, and high strength, ensuring the service life and safety of the clamping blocks 291.

[0037] It should be added that the transmission component in this embodiment includes two symmetrical pulleys 14, which are coaxially connected to the corresponding stirring shafts 12. A belt 15 is sleeved between the two pulleys 14. The pulleys 14 and the belt 15 are arranged between the two stirring shafts 12 to play a transmission role, which is conducive to the synchronous rotation of multiple stirring shafts 12.

[0038] It is worth noting that the first motor 16 and the second motor 3 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0039] In actual use, the user first connects the power supply of the first motor 16. The first motor 16 starts to work. The output shaft of the first motor 16 rotates, driving the stirring shaft 12 and the pulley 14 to rotate. Under the drive of the belt 15, the multiple pulleys 14 on both sides and the stirring shaft 12 rotate synchronously. The stirring shaft 12 synchronously drives the multiple stirring blades 13 to rotate and stir the polyferric sulfate in the chamber 1.

[0040] During discharge, the operator first places the container between the two clamping blocks 291 and rotates the handwheels 290 on both sides. The handwheels 290 drive the threaded rod 29 to rotate. As the threaded rod 29 rotates, the two clamping blocks 291 move synchronously relative to each other. When the clamping blocks 291 on both sides clamp the outer wall of the container, the operator stops rotating the handwheels 290. Then, the operator turns on the power of the second motor 3. The second motor 3 starts to work. The output shaft of the second motor 3 rotates, driving the lead screw 27 to rotate. At this time, the support plate 24 drives the sealing cover 20 to move downward. The sealing cover 20 moves closer to the container. When the sealing gasket 200 presses against the top of the container, the operator stops the power of the second motor 3. Finally, the operator loosens the valve 19. The polyferric sulfate in the silo 1 can then enter the container through the discharge pipe 18 and the telescopic pipe 21. Under the action of the sealing cover 20, the dust generated by the impact cannot spread to the outside.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
