Description

Technical Field

[0001] This utility model relates to the field of powder silo technology, and in particular to a powder silo for the production of quick-setting agents. Background Technology

[0002] The main components of accelerators include bauxite, sodium carbonate, and quicklime, which are hygroscopic and prone to caking. The powder silo for accelerator production is a core piece of equipment for ensuring product quality and production safety. Its design must closely integrate the material characteristics of the accelerator (such as hygroscopicity, caking tendency, and dust explosion risk) and process requirements. Powder silos are core equipment used in industrial production for storing powdered materials and are widely used in building materials, chemical, food, and pharmaceutical industries.

[0003] An existing powder silo for the production of accelerators (publication number: CN221606690U) has at least the following drawbacks: the humidity inside the silo cannot be determined; if the silo is not preheated (especially when the ambient temperature is low), the added hot material or material heated by steam may condense when it comes into contact with the silo wall due to the low temperature of the silo wall, forming local lumps; and there is a certain distance between the discharge pipe and the storage box, and the opening of the storage box is open, which can easily cause dust to fly through the opening and spread in the air when the material is discharged, affecting air quality and increasing material loss.

Both the air inlet and outlet pipes are fixedly connected to the cavity. The top cover is bolted to the opening of the powder tank. A feed pipe is integrally connected to the top of the top cover. A humidity detector is located on one side of the feed pipe and is fixedly connected to the top of the top cover. The bottom end of the humidity detector is inserted into the top of the top cover and located at the top of the powder tank. A drive motor is located on one side of the humidity detector and is fixedly connected to the top of the top cover. A stirring paddle is located inside the powder tank.

[0007] As a further embodiment of this utility model, the shaft of the stirring paddle passes through the upper cover and is fixedly connected to the output end of the drive motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Before feeding, activate the humidity detector on the top of the cover via the control panel. The detection end of the humidity detector passes through the cover and is located inside the powder tank to detect the humidity inside the powder tank. If the humidity inside the powder tank is high, open the valve of the connecting pipe to allow steam to enter the cavity of the powder tank through the air inlet pipe, heat the inner liner of the powder tank, and reduce the humidity inside the powder tank. Preheating the inner cavity of the powder tank with steam before feeding can make the wall temperature close to the material temperature, reduce the risk of condensation, maintain the looseness of the material, and avoid clogging of pipes or valves during unloading.

[0014] 2. The worker places the collection box on top of the base, weighs the collection box using an electronic scale, and then activates the drive cylinder. The extension end of the drive cylinder pushes the cover plate down, moving it to the top of the collection box opening and closing it to prevent dust from affecting the surrounding air quality during material discharge. As the cover plate moves down, the cloth tube unfolds, allowing the material to pass through the cloth tube and directly into the collection box. The cloth tube is deformable and foldable, suitable for collection boxes of different heights. It can also be disassembled and cleaned, and reused multiple times, making it environmentally friendly. Furthermore, the cloth tube prevents material from flying during discharge, reducing material loss. Attached Figure Description

An air inlet pipe 101 is fixedly connected to the outer wall of the top of the powder tank 1. An air outlet pipe 102 is fixedly connected to one side of the outer wall of the bottom of the powder tank 1. Both the air inlet pipe 101 and the air outlet pipe 102 are fixedly connected to the cavity 103. The top cover 2 is fixedly connected to the opening of the powder tank 1 by bolts. A feed pipe 205 is integrally connected to the top of the top cover 2. A humidity detector 204 is provided on one side of the feed pipe 205. The humidity detector 204 is fixedly connected to the top of the top cover 2. The bottom end of the humidity detector 204 is inserted into the inside of the top cover 2 and located on the top of the powder tank 1. A drive motor 203 is provided on one side of the humidity detector 204. The drive motor 203 is fixedly connected to the top of the top cover 2. A stirring paddle 201 is provided inside the powder tank 1.

[0026] During use, before feeding, activate the humidity detector 204 on the top of the cover 2 via the control panel. The detection end of the humidity detector 204 penetrates the cover 2 and is located inside the powder tank 1 to detect the humidity inside the powder tank 1. If the humidity inside the powder tank 1 is high, open the valve of the connecting pipe to allow steam to enter the cavity 103 of the powder tank 1 through the air inlet pipe 101 to heat the inner liner of the powder tank 1 and reduce the humidity inside the powder tank 1. Preheating the inner cavity of the powder tank 1 with steam before feeding can make the wall temperature close to the material temperature, reduce the risk of condensation, maintain the looseness of the material, and avoid clogging of pipes or valves during unloading.

[0027] In this embodiment, the shaft of the stirring paddle 201 passes through the upper cover 2 and is fixedly connected to the output end of the drive motor 203. The bottom of the upper cover 2 is provided with a scraper 202, and both the top and bottom ends of the scraper 202 are fixedly connected to the shaft of the stirring paddle 201. A bin wall vibrator 104 is fixedly connected to one side of the outer wall of the powder tank 1. The bin wall vibrator 104 is located at the top of the air outlet pipe 102. The bottom end of the scraper 202 is provided with a discharge pipe 105.

[0028] During use, the accelerator enters the powder tank 1 through the feed pipe 301. The drive motor 203 on the top of the cover 2 is started. The output end of the drive motor 203 drives the stirring paddle 201 to rotate, stirring the accelerator. At the same time, the stirring paddle 201 drives the scraper 202 to rotate. The scraper 202 rotates and scrapes the accelerator on the inner wall of the powder tank 1, avoiding the accelerator from adhering to the inner wall of the powder tank 1 and increasing the loss. When discharging, the silo wall vibrator 104 runs to accelerate the material discharge.

[0029] In this embodiment, the feeding pipe 105 is integrally connected to the bottom of the powder tank 1. The bottom of the powder tank 1 is provided with a discharge box 3. The top and bottom sides of the discharge box 3 are integrally connected with the feeding pipe 301 and the discharge pipe 304 respectively. The feeding pipe 301 is fixedly connected to the feeding pipe 105 by bolts. The bottom of the feeding pipe 301 is provided with a discharge plate 302. The two ends of the discharge plate 302 are rotatably connected to the inside of the discharge box 3. The back side of the discharge box 3 is provided with a rotating motor 303.

[0030] In use, a control valve can be installed on the outer wall of the feeding pipe 105 to control the closure of the pipe, which facilitates the mixing of materials. After the powder is finished, the material enters the discharge box 3 through the feeding pipe 301. The rotating motor 303 is started, and the output end of the rotating motor 303 drives the discharge plate 302 to rotate, so that the material falls into the fan-shaped space of the discharge plate 302. The rotating discharge plate 302 discharges the material in a quantitative manner.

[0031] In this embodiment, the output end of the rotating motor 303 is fixedly connected to the shaft of the discharge plate 302, the bottom of the discharge box 3 is fixedly connected to the second support 5, the discharge pipe 304 is connected through the middle of the second support 5, the rotating motor 303 is fixedly connected to the top of the second support 5, the two outer sides of the discharge box 3 are fixedly connected to the drive cylinder 501, and the bottom of the second support 5 is provided with a cover plate 504.

[0032] When in use, when the collection box 6 is full, stop the operation of the rotating motor 303 to stop the rotation of the discharge plate 302, so as to prevent the material from overflowing and making it convenient for the staff to replace the collection box 6. Start the drive cylinder 501, and the telescopic end of the drive cylinder 501 pushes the cover plate 504 down. The cover plate 504 moves to the top of the box opening of the collection box 6 and closes the box opening of the collection box 6 to prevent dust from flying during material discharge and affecting the air quality in the vicinity.

[0033] In this embodiment, a cloth tube 503 is fixedly connected to the top of the cover plate 504, and a fixing frame 502 is fixedly connected to the top of the cloth tube 503. The fixing frame 502 is fixedly connected to the bottom of the second support frame 5 by bolts. The cloth tube 503 is sleeved on the outside of the discharge pipe 304. A first support frame 4 is provided at the top of the second support frame 5. The first support frame 4 is fixedly connected to the bottom outer wall of the powder tank 1. A base 7 is provided at the bottom of the cover plate 504.

[0034] During use, as the cover plate 504 moves down, it causes the cloth tube 503 to unfold, allowing the material to pass through the cloth tube 503 and directly enter the collection box 6. The cloth tube 503 is deformable and can be folded, making it suitable for collection boxes 6 of different heights. The cloth tube 503 can also be disassembled and cleaned, and can be reused multiple times, making it environmentally friendly. In addition, the cloth tube 503 can also prevent the material from flying during discharge, reducing material loss.

The telescopic ends of the cylinder support columns 702 are fixedly connected to the bottom of the first support frame 4. The second support frame 5 is fixedly connected to the outside of the cylinder support columns 702. An electronic scale 701 is provided between the cylinder support columns 702. The electronic scale 701 is fixedly connected to the top of the base 7. A collection box 6 is provided at the bottom of the second support frame 5. The collection box 6 is located on top of the electronic scale 701.

[0036] In use, the worker places the collection box 6 on top of the base 7 and weighs the collection box 6 using the electronic scale 701. The telescopic end of the cylinder support 702 supports the second support frame 5 and the powder tank 1. After the discharge box 3 is removed from the second support frame 5, the cylinder support 702 is activated. The telescopic end of the cylinder support 702 moves the second support frame 5 and the powder tank 1 downward, making it convenient for the worker to remove the top cover 2 and perform maintenance and inspection on the inside and outside of the powder tank 1.

[0037] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Before feeding, the humidity detector 204 on the top of the cover 2 is activated through the control panel. The detection end of the humidity detector 204 penetrates the cover 2 and is located inside the powder tank 1 to detect the humidity inside the powder tank 1. If the humidity inside the powder tank 1 is high, the valve of the connecting pipe is opened to allow steam to enter the cavity 103 of the powder tank 1 through the air inlet pipe 101 to heat the inner liner of the powder tank 1 and reduce the humidity inside the powder tank 1. The powder tank 1 is preheated with steam before feeding (i.e., the tank body is preheated), which can make the wall temperature close to the material temperature, reduce the risk of condensation, maintain the looseness of the material, and avoid clogging of pipes or valves during unloading. Workers will collect The material bin 6 is placed on top of the base 7. The electronic scale 701 weighs the material bin 6 after tareing. Then, the drive cylinder 501 is activated. The telescopic end of the drive cylinder 501 pushes the cover plate 504 down, so that the cover plate 504 moves to the top of the opening of the material bin 6, closing the opening of the material bin 6 to prevent dust from flying during material discharge and affecting the surrounding air quality. As the cover plate 504 moves down, it drives the cloth tube 503 to unfold, allowing the material to pass through the cloth tube 503 and directly into the material bin 6. The cloth tube 503 is deformable and can be folded, making it suitable for material bins 6 of different heights. At the same time, the cloth tube 503 can also be disassembled and cleaned, and can be reused multiple times, which is environmentally friendly. In addition, the cloth tube 503 can also prevent the material from flying during discharge.
