Description

Technical Field

[0001] This utility model belongs to the field of material storage technology, and specifically relates to a storage and turnover device for adding powdered materials. Background Technology

[0002] Powdered material storage devices are equipment used to store powdered materials and are widely used in industries such as chemical, food, pharmaceutical, and building materials. During the storage period, there are usually situations where materials are used and additional storage is required, so the storage device needs to have the corresponding ability to store and retrieve materials.

[0003] The patent specification with publication number CN215286411U discloses a steel slag powder storage device, which includes a storage tank, a feeding module, a guiding module, a sealing module, and a discharging module. The feeding module is installed on the top of the storage tank, the guiding module is installed inside the storage tank, the sealing module is installed between the feeding module and the guiding module, and the discharging module is installed at the bottom of the storage tank. The sealing module includes a double-headed cylinder, a first sealing mechanism, and a second sealing mechanism. The double-headed cylinder is installed at the guiding module by a bracket, and the piston rod at one end of the double-headed cylinder is fixedly connected to the first sealing mechanism.

[0004] When in use, this storage device uses a cylinder installed below the feed inlet inside the storage tank. The cylinder's extension and retraction control the sealing state of the feed inlet, ensuring the device is sealed after feeding. However, this technical solution has a drawback: after material is added to the storage tank, the feed inlet, pushed upwards by the cylinder and sealed with a sealing ring, completely seals the tank. However, the powder thrown up after adding material increases the internal pressure. Furthermore, during storage, the internal pressure of the powdered material gradually increases due to temperature changes, chemical reactions, or gas release. Over time, this can lead to excessive pressure damaging the equipment and the risk of the powder exploding upon contact with static electricity or a source of ignition.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a storage and turnover device for adding powdered materials. The technical problem to be solved is as follows: During the storage of powdered materials after adding materials, the pressure inside the tank is too high in order to maintain the airtightness of the tank, which poses a safety hazard.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A storage and turnover device for adding powdered materials includes a storage tank, a movable component installed on the periphery of the storage tank, a material handling component installed at the bottom of the storage tank, a viewing window provided on one side of the bottom of the storage tank, and a viewing mirror installed on one side of the top of the storage tank, a manhole component installed in the middle of the top of the storage tank, a pressure relief component installed on one side of the top of the storage tank for balancing the air pressure inside and outside the storage tank, and a material storage component installed on one side of the top of the storage tank for adding material.

[0009] As a further embodiment of this utility model: the bottom of the storage tank is funnel-shaped, the strip window is installed along the middle of one side of the bottom of the storage tank, and the sight glass is separate from the strip window.

[0010] As a further embodiment of this utility model: the manhole assembly includes a manhole tube disposed at the middle of the top of the storage tank, a manhole cover rotatably connected to one side of the manhole tube at the top of the storage tank, and a cover plate rotatably connected to the other side, and a locking shaft is installed between the cover plate and the top of the manhole cover.

[0011] As a further embodiment of this utility model: the pressure relief assembly includes an exhaust pipe fixedly connected to the top of the storage tank, limit frames fixedly connected to both sides of the top of the exhaust pipe, a pressure adjusting pin threadedly connected to the top of the limit frame, a top limit block rotatably connected to the bottom of the pressure adjusting pin below the limit frame, a bottom limit block inserted into the middle of the top of the exhaust pipe, and a spring installed between the top limit block and the bottom limit block.

[0012] As a further embodiment of this utility model: a feed inlet is provided on one side of the top of the storage tank, the storage assembly includes a feed plate installed on one side of the feed inlet, a slide rail is installed on one side of the feed plate, a slider is slidably connected to the slide rail, a shift plate is fixedly connected to the top of the slider, a cylinder is installed on one side of the shift plate, a feeding hopper is fixedly connected to the middle of the top of the shift plate, a material transfer port is provided in the middle of the shift plate, and a feed pipe is provided on the feed plate adapted to the feed inlet.

[0013] As a further embodiment of this utility model: the material receiving component includes a material receiving cylinder installed at the bottom of the storage tank, and a drive motor is installed on one side of the material receiving cylinder.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a feeding port on one side of the top of the storage tank and installing a storage component on one side of the feeding port, and a pressure relief component on one side of the top of the storage tank, during use, the cylinder drives the feeding port at the bottom of the feeding hopper to align with the feeding pipe to add material. After the addition is completed, the cylinder retracts, and the feeding pipe is sealed by the end of the shift plate, completing the resealing of the storage tank. After the addition is completed, the air pressure inside the storage tank can be balanced with the external air pressure by lifting the bottom limit block through the pressure relief component. The purpose is to maintain the sealing and the balance of internal and external air pressure of the storage tank during the storage of materials. This ensures that the sealing of the storage tank will not be damaged during the frequent material addition process, and the balance of internal and external air pressure during the addition ensures the safety of the staff when adding materials. Thus, the storage tank has the characteristics of maintaining a seal during storage and maintaining safety when adding materials, achieving dual protection for materials and staff.

[0016] 2. By installing a manhole assembly at the top center of the storage tank, workers can thoroughly clean the residue inside the tank by opening the manhole assembly. Combined with the convenient material replenishment by the storage assembly, the storage tank can maintain the purity of the stored materials for a long time. In addition, by installing sight glasses and strip windows at the top and bottom of the storage tank, workers can easily observe the storage situation inside the tank when storing and retrieving materials, thereby improving the convenience of using the storage tank.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0025] like Figures 1 to 5 As shown, a storage and turnover device for adding powdered materials includes a storage tank 1, a moving component 2 installed on the periphery of the storage tank 1, a material handling component 3 installed at the bottom of the storage tank 1, a viewing window 4 provided on one side of the bottom of the storage tank 1, and a viewing mirror 5 installed on one side of the top of the storage tank 1, a manhole component 6 installed in the middle of the top of the storage tank 1, a pressure relief component 7 installed on one side of the top of the storage tank 1 for balancing the air pressure inside and outside the storage tank 1, and a material storage component 8 installed on one side of the top of the storage tank 1 for adding material.

[0026] It should be noted that the moving component 2 includes four support rods 21 fixedly connected to the top periphery of the storage tank 1. Each support rod 21 is equipped with a universal self-locking wheel 22 at its bottom end, and handles 23 are installed on both sides of the top of the storage tank 1. Thus, the storage tank 1 can be moved conveniently with the help of the universal self-locking wheels 22 and handles 23. The material picking component 3 includes a material picking cylinder 31 installed at the bottom of the storage tank 1. A drive motor 32 is installed on one side of the material picking cylinder 31. Specifically, a horizontally arranged multi-bladed rotating component is installed inside the material picking cylinder 31. The blades can rotate in a vertical plane. The output end of the drive motor 32 is connected to the rotating component. After the drive motor 32 is started, the powdery material is carried to the outside of the storage tank 1 by the rotation of the blades by its own weight and the vertically rotating rotating component. When no material is being picked up, the bottom of the material picking cylinder 31 is sealed by a steel plate.

[0027] like Figure 1 As shown, the bottom of the storage tank 1 is funnel-shaped, and the strip window 4 is installed along the middle of one side of the bottom of the storage tank 1. The sight glass 5 is separate from the strip window 4.

[0028] It should be noted that the bottom of storage tank 1 is funnel-shaped to facilitate material unloading. Both the viewing window 4 and the sight glass 5 are made of transparent tempered glass. The viewing window 4 is installed vertically along the bottom of storage tank 1, and the sight glass 5 is installed on one side of the top of storage tank 1. The purpose of installing two separate observation windows on storage tank 1 is that storage tank 1 has two states during the process of storing and retrieving materials. When storage tank 1 is storing materials, the staff needs to observe whether storage tank 1 is full. When storage tank 1 is retrieving materials, the staff needs to observe how much material is left in storage tank 1. Because the observation positions are different, the two observation points cannot directly cover the visibility range of the other. Therefore, it is necessary to set up two separate observation points to avoid the staff being unable to take into account the actual observation needs of storing and retrieving materials at the same time, thereby improving the convenience of using storage tank 1.

[0029] like Figure 2 As shown, the manhole assembly 6 includes a manhole tube 61 located at the top center of the storage tank 1. One side of the manhole tube 61 is rotatably connected to the manhole cover 62 at the top of the storage tank 1, and the other side is rotatably connected to the cover plate 63. A locking shaft 64 is installed between the cover plate 63 and the top of the manhole cover 62.

[0030] It should be noted that during the continuous process of adding and removing materials, some residual materials that are difficult to clean will gradually accumulate inside the storage tank 1. When the type of stored material is changed, in order to maintain the purity of the stored materials, the original residual materials need to be thoroughly cleaned. At this time, it is necessary to rotate and unlock the locking shaft 64 to open the manhole cover 62 from the top of the manhole tube 61, so that the staff can enter the storage tank 1 to carry out system cleaning, so as to maintain the purity of the materials stored in the storage tank 1 for a long time.

[0031] like Figure 2 and Figure 3 As shown, the pressure relief assembly 7 includes an exhaust pipe 71 fixedly connected to the top of the storage tank 1. Limiting frames 72 are fixedly connected to both sides of the top of the exhaust pipe 71. A pressure adjusting pin 73 is threadedly connected to the top of the limiting frame 72. The bottom end of the pressure adjusting pin 73 is rotatably connected to a top limiting block 74 below the limiting frame 72. A bottom limiting block 75 is inserted into the middle of the top of the exhaust pipe 71. A spring 76 is installed between the top limiting block 74 and the bottom limiting block 75.

[0032] It should be noted that when the internal air pressure of the storage tank 1 increases, the internal air is forced through the exhaust pipe 71 to the inserted bottom limit block 75. The bottom limit block 75 presses against the spring 76, the spring 76 contracts and moves upward, and the bottom limit block 75 moves upward simultaneously. The top of the exhaust pipe 71 opens, and the internal air pressure of the storage tank 1 is balanced. Subsequently, the spring 76 returns to its original position, and the storage tank 1 returns to a sealed state. The pressure relief component 7 can be adjusted by adjusting the downward movement distance of the top limit block 74 through the pressure adjusting pin 73. That is, while maintaining the long-term sealing of the storage tank 1 through the pressure relief component 7, it can also prevent the internal air pressure from being too high, thereby maintaining the safety of the internal air pressure of the storage tank 1 during use.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, a feed inlet 9 is provided on one side of the top of the storage tank 1. The storage assembly 8 includes a feed plate 81 installed on one side of the feed inlet 9. A slide rail 82 is installed on one side of the feed plate 81. The slide rail 82 is slidably connected to a slider 83. A shift plate 84 is fixedly connected to the top of the slider 83. A cylinder 85 is installed on one side of the shift plate 84. A feeding hopper 86 is fixedly connected to the middle of the top of the shift plate 84. A material transfer port 87 is provided on the shift plate 84. A feed pipe 88 is provided on the feed plate 81 to adapt to the feed inlet 9.

[0034] It should be noted that when adding material to the storage tank 1, the output end of the cylinder 85 pushes the shift plate 84. Under the limiting sliding of the slide rail 82 and the slider 83, the shift plate 84 pushes the material transfer port 87 on it toward the feed pipe 88. When the feed pipe 88 and the material transfer port 87 are connected, the material added in the feeding hopper 86 is sent into the storage tank 1 through the feed port 9. After the addition is completed, the telescopic rod of the cylinder 85 retracts, and the shift plate 84 drives the top feeding hopper 86 to move away from the feed port 9 until the side of the shift plate 84 close to the feed port 9 covers the feed pipe 88, so that the storage tank 1 becomes sealed again. That is, the material can be conveniently added to the storage tank 1 through the storage component 8, and the storage tank 1 can be sealed again after the addition is completed, thereby maintaining the airtightness of the storage tank 1 during storage.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
