Description

Technical Field

[0001] The utility model relates to the field of powder material storage, in particular to a material storage tank structure for preventing powder material from sinking to the bottom. Background Art

[0002] Powder usually refers to the raw materials of powdered products. Many products are produced and transported in powder form. Therefore, in each production stage of powder products, powder needs to be temporarily or permanently stored, and these storage equipment need to have good moisture-proof performance to ensure that the storage environment of the powder is dry and avoid the quality of the powder. Therefore, most of them are implemented in the form of storage tanks. A certain amount of powder is loaded into storage tanks of different shapes, and then the top of the storage tank is sealed; when discharging, the discharge port at the bottom of the storage tank is opened to complete the discharge process. This type of powder storage tank basically solves the problems of dry sealing, moisture-proof and mildew-proof, and avoiding cross contamination required for powder storage. However, this storage structure still has problems such as powder easy to sink to the bottom and easy to block the discharge port, resulting in low discharge efficiency and complicated discharge operation.

[0003] To this end, Chinese patent publication number CN213769892U discloses a powder storage tank, which utilizes a dredging mechanism connected to a tank body, the dredging mechanism comprising a stirring rod, a transmission assembly and a power source, the stirring rod is vertically arranged and its axis and the axis of the discharge pipe are located in the same straight line, the peripheral wall of the stirring rod is provided with a thread along the axial direction, the transmission assembly comprises a worm, a worm wheel and a mounting plate for mounting the worm wheel, the mounting plate is located in the tank body and fixedly connected to the inner wall of the tank body, one side of the circular side wall of the worm wheel is rotatably connected to the mounting plate, a threaded hole is provided in the axis of the worm wheel, the stirring rod is penetrated into the threaded hole of the worm wheel and is threadably connected to the worm wheel, one end of the worm along the axial direction is meshed with the outer wall of the worm wheel, the end of the worm away from the worm wheel penetrates the side wall of the tank body and can rotate, and the end of the worm away from the worm wheel is connected to the power source, which has the effect of reducing the blockage of the discharge port by the agglomerated powder, thereby achieving the possibility of increasing the discharge speed.

[0004] However, such a powder storage tank is a through-type storage structure, that is, there is a single storage space from the top to the bottom of the tank. In this storage method, when storing a large amount of powder, the powder that first enters the bottom of the tank will be subject to the pressure of the powder that enters the tank later, which will still cause agglomeration and lead to powder sedimentation, which is not conducive to rapid discharge of powder. In the long run, it will also cause the quality of the powder to deteriorate during storage. At the same time, the existing storage tank is not provided with a structure that is convenient for cleaning the inside of the tank, and the residual powder on the inner wall of the tank and the surface of the parts and in the gaps of the tank cannot be cleaned, so that the cleaning problem of the interior of the existing storage tank cannot be guaranteed. In addition, the long-term inability to clean the inside of the storage tank may reduce the service life of the storage tank. Utility Model Content

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-10 As shown, a storage tank structure for preventing powder from sinking to the bottom includes a tank body 1; an anti-sinking structure 2 and a limiting structure 3, the anti-sinking structure 2 is evenly installed on the inner wall of the tank body 1 along the axis of the tank body 1, and the size of the anti-sinking structure 2 is slightly smaller than the cross-sectional size of the inner wall of the tank body 1; the anti-sinking structure 2 includes a layering plate 21 and a flip shaft rod 22, every two symmetrical layering plates 21 form a group, and a flip shaft rod 22 is provided on one side of the layering plate 21, and the flip shaft rod 22 is rotatably connected to the inner wall of the tank body 1 through a bearing; and a limiting structure 3 is also included, the limiting structure 3 is installed on the inner wall of the tank body 1 below the layering plate 21, and the number of the limiting structures 3 is the same as the number of the layering plates 21 and corresponds one to one.

[0030] The inner wall of the tank body 1 is divided into a plurality of storage spaces by the layering plates 21. Specifically, two symmetrical layering plates 21 are combined into a set of anti-sinking structures 2, which can realize layered storage of the powder in the tank body 1. The layering plates 21 are turned around the axis of the turning axis 22 by the turning shaft 22 arranged at one end of the layering plates 21. When feeding and storage are required, the layering plates 21 of the bottom layer are turned to be perpendicular to the axis of the tank body 1, and the powder is added. After adding an appropriate amount of powder, the layering plates 21 of the upper layer are turned to be perpendicular to the axis of the tank body 1. line, continue to add materials, and fill up each layer of the anti-sinking structure 2 in turn. Since the layered plates 21 separate the powder into multiple layers for storage, it can avoid the problem of the powder concentratedly exerting pressure on the bottom of the tank body 1 when stored in the same space, thereby causing the powder at the bottom of the tank body 1 to clump and sink to the bottom. When discharging is required, the layered plates 21 can be turned over from bottom to top in turn to be parallel to the axis of the tank body 1. The stored powder can smoothly fall along the discharge channel opened by the layered plates 21, and can be smoothly discharged from the discharge port at the bottom of the tank body 1, without causing the situation of being unable to discharge or incomplete discharging.

[0031] like Figure 1 , 4 As shown in Figures 5 and 9, a scraping assembly 4 is installed inside the tank body 1. The scraping assembly 4 includes a main shaft rod 41 and a scraper 42. The main shaft rod 41 is coaxial with the tank body 1, and a rotation connection is formed between the main shaft rod 41 and the tank body 1. The scrapers 42 are evenly distributed on the surface of the main shaft rod 41, and the number of the scrapers 42 is the same as the number of the layered plates 21 and corresponds one to one.

[0032] The main shaft rod 41 is connected to the rotation drive device through the top end. The rotation drive device can be set as a motor connected through a rigid coupling or as a manual rotation mechanism. The main shaft rod 41 drives the scraper 42 to rotate through the rotation drive device. Since the bottom of the scraper 42 is in contact with the surface of the stratification plate 21, when the scraper 42 rotates, the powder adhering to the surface of the stratification plate 21 can be concentrated, thereby solving the problem of powder deposition on the surface of each stratification plate 21. After the scraper 42 concentrates the powder, the stratification plate 21 is flipped over, and the concentrated powder will slide down the stratification plate 21 to complete the discharge.

[0033] like Figure 1 , 2 As shown in , 4 and 10, a blowing assembly 5 is installed on one side of the outer wall of the tank body 1, and the blowing assembly 5 includes a blower 51. A main air duct 52 is fixedly connected to the surface of the blower 51, and a plurality of blowing pipes 53 are arranged on the surface of the main air duct 52, and one end of the blowing pipe 53 passes through the inner wall of the tank body 1. The blowing pipe 53 is arranged above the layer plate 21, and the number of the blowing pipes 53 is the same as the number of the layer plates 21 and corresponds one to one, and a check plate 54 is movably connected to the inner wall of one end of the blowing pipe 53.

[0034] When the powder on the layering plate 21 is discharged, a small amount of powder may be adhered to the layering plate 21, the turning shaft, the scraper 42, the main shaft rod 41 and the inner wall of the tank body 1. At this time, the blower 51 is turned on to blow air into the tank body 1 through the main air duct 52 and the air outlet above each layer of the layering plate 21, so as to blow the small amount of powder adhered to the surface of the parts to the discharge port at the bottom of the tank body 1, thereby achieving the cleaning effect on the surfaces of the layering plate 21, the turning shaft, the scraper 42, the main shaft rod 41 and the inner wall of the tank body 1.

[0035] like Figure 1 , 5 As shown in FIGS. 7 and 8 , the limiting structure 3 includes a limiting rod 31 ; the limiting rod 31 is arranged at the bottom of the layered plate 21 and penetrates the surface of the tank body 1 , and the number of the limiting rod 31 is the same as the number of the layered plates 21 and corresponds one to one.

[0036] The limiting rod 31 provides linear driving power through a cylinder or a telescopic rod. When loading begins in the tank body 1, the layering plates 21 need to be turned horizontally from bottom to top to carry the powder. When a layer of layering plates 21 is turned horizontally, the limiting rod 31 can be started to extend from the inner wall of the tank body 1, and a support limit is provided at the bottom of the layering plate 21, so that the layering plate 21 will not tilt due to the weight of the powder, thereby achieving the effect of layered storage of the powder. When the tank body 1 needs to discharge the material, the limiting rod 31 is first retracted into the inner wall of the tank body 1 through an external linear driving device such as a cylinder or a telescopic rod, so that the layering plate 21 loses its support limit, and then the layering plate 21 is rotated to a vertical state by flipping the shaft rod 22 to complete the unloading of the powder.

[0037] like Figure 2 , 6 As shown in , 7, 8, and 10, the storage tank structure also includes a servo motor 6, a sensor 7 and a controller 8; the servo motor 6 is installed on one side of the outer wall of the tank body; a driving gear 9 is installed at the output shaft of the servo motor 6, and a passive gear 10 installed on one end of the flip shaft 22 is meshed on one side of the surface of the driving gear 9; the sensor 7 is installed on the bottom side of the layered plate 21; and the controller 8 is communicatively connected with the servo motor 6 and the sensor 7 respectively.

[0038] The sensor 7 is a rotary resistance material level sensor 7, which is arranged on one side of the bottom of the stratification plate 21. When the storage tank is loaded with materials, the powder is loaded through the feed port on the upper side of the tank body 1, and the powder is first accumulated on the surface of the bottom stratification plate 21. After a certain period of time of loading into the tank body 1, the sensor 7 detects the accumulation height of the powder, and then sends a signal to the controller 8. The controller 8 controls the servo motor 6 to start, and drives the passive gear 10 at one end of the flip shaft 22 through the driving gear 9, so that the stratification plate 21 of the upper layer starts to rotate to a horizontal state, completing the loading of the next layer and starting to load the stratification plate 21 of the upper layer.

[0039] like Figure 1 , 4 As shown in , 5 , a layered sealing ring 11 is welded to the inner wall of the can body at the top of the layered plate 21; the number of the layered sealing rings 11 is the same as the number of the layered plates 21 and corresponds one to one, the top inner diameter of the layered sealing ring 11 is the same as the cross-section of the inner wall of the can body, and the bottom inner diameter of the layered sealing ring 11 is smaller than the surface size of the layered plate 21.

[0040] In order to enable the stratification plate 21 to flip freely on the inner wall of the tank body 1, after the two stratification plates 21 are flipped to a horizontal state and merged, the size of their upper surfaces is set to be slightly smaller than the cross-sectional size of the inner wall of the tank body 1. At the same time, a stratification sealing ring 11 is welded to the inner wall of the tank body 1 above the stratification plate 21. The bottom of the stratification sealing ring 11 fits against the upper surface of the stratification plate 21, and the stratification sealing ring 11 has a structure with a large top opening and a small bottom opening. The size of its top inner diameter is the same as the cross-sectional size of the inner wall of the tank body, which is convenient for the powder to fall onto the stratification plate 21, and the size of its bottom inner diameter is smaller than the size of the upper surface after the two stratification plates 21 are merged, which is convenient for sealing between the stratification plate 21 and the inner wall of the tank body 1.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
